Cool! Our very own Malaysia rom! Will flash this to try! keep it bro1
Now wheres that thanks button? Nvm Thanks!

where's the link for this cool rom?

still under development bro
tweaking some little code and compiling it later will take 4 to 6 hours

nice one.. at last we've our own malaysian rom..
can't wait to flash this rom...
thanks for the effort...

bravo.. gud luck bro..
hope it can replace the old trusty Phantom ROM..

how is this compared to phantom, any performance difference that we can see???

Bro, please port to Ideos X5, can?

It's hard to say for now, as Phantom is a Froyo rom while CM7 based ROMs are Gingerbread. Performance depends on configuration the ROM applies, for example, Phantom (Froyo) doesn't have OpenGL ES 2 enabled by default, where any Gingerbread have support for it. Same as Gingerbread allows more optimization for ARM platform, especially ARM6+ where Froyo are still better then Enclair but outdated in terms of CPU management.

Although I have to admit Froyo ROMs such as Phantom, uses less memory and more stable then current Gingerbread custom ROMs.

Hehe, I'm sorry bro, CM7 doesn't have Ideos x5 source, even on backport ones.
Although I can compile the ROM according to it's hardware, it won't happen in near future.

nice, cant wait to try this.
btw, good luck with this project bro.

Looks like I've to save up and buy a Mi300 then.

Hehe.. trade the x5 for my mi300 la..
Joking anyway if all goes well, I see what I can do about the x5 port



Uploading the rom now after an all nighter coding and testing. Hope you guys will enjoy it later

ive been using CM7 2.3.7 for a while n i can say im quite happy with the performance.. n i have a feeling this coming rom will be great. hhehehehe

Download links are up
see the OP for more info and download links.
Thanks for all the support sifus, even though I'ma newbie here

my gosh.. just download n flash to eav5 yesterday.. xlarat nak donlod lagi.. berukbond reach the limit.. tomoror going to kk.. can copy via pendrive??

I know your pain
Sure thing but I won't confirm if I'm "turun" or not. If I am, can flash it on the spot also

TS, is it because of the openGL ES 2 that scrolling in gingerbread is really smooth compared to froyo, even in phantom rom?.. i cant really stand the stuttering when scrolling when using froyo, thats why i'd rather stick with gb even tho it really sucks the juice

TS?
Gingerbread does have almost all of it's ui hw accelerated. So it is much smoother then froyo. Even its launcher are hw accelerated. About battery life, it does consume a little more, but after a week usage after battery stat eipe, u will notice a little improvements, juice defender are also recommended

What is this kernel thing?
Never flashed my spice..so I don't know much
Does flashing to your custom ROM automatically update/change this kernel,or do I have to find and update it manually?Any guide or info about this would be great

Every ROM update have it's own kernel built in and will be installed automatically upon flashing.
Kernel is a basic low level code/software that allows the very basic of OS operations, basically kernel is a software that sit between the OS itself and the hardware. Meaning both will not work if there are no kernel. This applies to every OS whether in phones or PC.

There are some custom kernels for Android, that are available on the net. For example SuperAOSP and Ubuntu #3 EA kernel. Although the process is simple enough by flashing via recovery mode, it is advice able to only flash kernels that are compatible with your device.

downloading and installing it now..

eh why after install, got spice logo looping o.o

This post has been edited by miloy2k: Oct 3 2011, 03:06 PM

hmm..that's weird..they're supposed to be no csl logo on boot.. that could be caused from incomplete flash..try and reflash again with data and cache wipe..if that fails, try to flash 2.1 rom, stock or firetrap 2.1 and reflash mygingerb again..

will try again later,

now reset back to 2.1 and then back to phantom

TS = Thread Starter = You

I see
Hehe, I'm still new here so didn't know the terms here. Thanks bro
Will keep it in mind.

bro.. i stay at api2 centre until thusday nite b4 going back to tawau..if ur have a tym, let me know..

bro sorry for the question but can i use this rom for mi310 or mi320???

Apparently no, sorry bro
There are several cause for this, one is I don't know if the chipset are the same as the mi300 or not, as Mi300 uses MSM7x27 SURF. The optical trackpad driver are missing, as mi300 uses trackball, and other factors such as internal ROM installation space.

For me Gingerbread is smoother, and uses less battery wor...... Dunno la..... But we all enjoy the fact Gingerbread makes our phone less laggy..........

Agreed, some report on my battery usage for MyGingerB 1.0 (seriously, i need to renamed that on the next release, suggestion? )

It lasted 17hours before reaching the limit of 5% shut down. So yeah, it lasted the whole working day at least, typical, if not better then other smartphones with GB out there

Well done Keep it up
Mi300 now @ market how much?
wah 2.3.7

tried your rom, looks promising.. but me touchscreen doesn't work

rolled back

Can you upload the kernel only?

Owh about that, have you imported any keyboard with titanium backup?
I believe that with the new kernel (2.6.35.x) doesn't compatible with any keyboard calibration data, same have happened to other 2.3.7 based rom on other phones .
The best way would be wipe data,cache and dalvik without reflashing, and walla the touch is working again(it happened to me also ).

Be sure to not import any data from any keyboard app, or any app that included hardware control permission.

nice one!!!good job!

i can't even touch the droid on startup... so never import nothing or whatsoever

nice one, won't have to use 'foreign' rom after this

what i've done:

currently using cm7-eav5.1 + #3 kernel
wipe data/factory reset
wipe cache
wipe dalvik
install .zip (gingerb)
install .zip (gapps)
reboot

touchscreen doesnt work
so back to recovery mode

wipe data/factory reset
wipe cache
wipe dalvik
reboot

touchscreen still does not work

so i restore to my previous rom

It seems that there are some leftover data after flash. Try and boot into recovery and wipe /data, cache and dalvik (in the advance menu), if again failed, try and reflash with wiping all the above before flashing.

The 2.6.35.x kernel is giving problems post installation for some device, randomly,
Since most of other Gingerbread rom using the 2.6.32.x, which is still a froyo kernel, most hardware data (calibration and such) will have problem.

Thanks for the feedback bro will include fix on next release (stable)



Thanks to your thread I finally convinced to bought this phone

gingerbread's UI is fully hw accelerated right? but why is the 3d game performance still not that good compared to froyo? is it possible to tweak it to match froyo 3d game performance.. ive tried chainfire3d but still cant get it to be smooth especially 3d racing game like raging thunder

p/s: if u change ur rom name to something that include 1malaysia najib will give u a job for sure, hahahahaha...

This post has been edited by gocke55014: Oct 4 2011, 01:16 PM

touchscreen doesn't work on my phone too..
so, do i've to go back to stock rom b4 flashing to this rom?

hi TS, can you make an .nbo version for the firmware?

Gingerbread reacts to hardware differently then Froyo, again, some games, most of it currently are optimized for Froyo. While this is not noticeable in high end hardware, low to mid range phone hardware do notice it, like our mi300 for example. Nothing can be done except to wait for Google to fix this. Even the kernel's wakelock issue in Gingerbread haven't been solve officially. Most of the fix are from open source developers in xda-dev.
We also have to wait for Qualcomm to release a better driver for MSM7x27's Adreno 200.

In a nut shell, Gingerbread UI is silky smooth because it is optimized for Gingerbread, same as Gingerbread launcher port to froyo will not work smooth because the lack of HW accelerated and are not optimized for Froyo.



For ppl who have touchscreen issue, try and flash this hotfix, the hotfix will be included in stable release later on, but since there'e much to do with it, I'll uploaded the kernel with touch driver fix (seems I messed it up from compiling process sorry guys) download it here

Flash it with recovery mode, be sure to wipe data, cache, dalvik and battery stat. A must for new Gingerbread kernel.

Currently not possible bro
There's a lot of work to do if i want to convert the rom to nb0.
Flashing via recovery are more safer then SUT (nb0 flash)

Although I will try to make on as a backup later on

tried your kernel, still wont fix touchscreen problem..
maybe just me using Edgar86's EAv5.1

oh well, just wait for your stable release then

This is great news, keep it up sahabat

Updated the OP with stable download links
keep on giving feedback guys, thanks

the touchscreen also doesnt on my phone with the stable release..

Hm, sorry to hear that bro
Did you install the Google app after first boot or before first boot?
Can you try below real quick..tell me the result.

Try flashing the google apps before first boot, meaning, in recovery mode, after flashing the ROM, then immediately flash the google apps zip file, before reboot that is. If that fixes it, I'll make a quick fix for it later on.

IF you have flash the google apps zip file before first boot, then I will also make a quick fix for it.

thanks bro

can i straight update to this rom from cm eav5 + #3kernel?

hm.. i've tried both way, b4 first boot n also after first boot. no change.
n i also flash the fix kernel that u upload it just now but still no change..
thnx 4 the hard work bro..

Whoa, so hard being a cooker eh? soldier on my fren, waiting for d stable release...

How about not flashing google apps at all.
Well, I've uploaded a fix, seems like the SetupWizard.apk are conflicting when there's no google app framework installed. I've replaced it with default provision.apk as default first boot, hopefully that will fix the issue.. Check the OP for download links.
Sorry for the inconvenience bro

Yeah, it's hard to cooked something as simple as Gingerbread
Every developer have it's up and down, that's why in the law of computers, there's no perfect code exist
I'm just confuse why it work fine on my phone, while some don't.
Thank you for the encouragement bro, will be strong to the end

feedback:tested v1.0 stable, v1.0.1

touchscreen still not working

This post has been edited by ralph_d: Oct 5 2011, 09:23 AM

MyGingerB 1.0.2 uploaded, more info on OP.

my feedback..
this rom works well on my phone.. no more touchscreen problem.. gud job bro.
btw, is it using kernel 2.6.32.9 EA#3..? not 2.6.35.13?..

Owh ya, forgot to mentioned it in the release notes.
The 2.6.35.13 stock CM kernel does have problem, including the touch screen module problem on first boot. So I used stable 2.6.32.x one as a temporary replacement. Users now can also use any other kernel out there for the z71 variant without any problem now.
I haven't checked out the 2.6.35.11 by edgar (thank ralph_d for pointing that out) but you can try it

You can also flash the tweaked stock CM7 2.6.35.11 from the mygingerb 1.0.1 now since the touchscreen issue are affecting first boot process only.

I'm currently developing my own kernel for this ROM, but that will take a while.

ok.. gud luck in developing..
glad to use the rom from local developer...

Thanks bro...adding to the proud user list?

got proud user list eh..
pls add me.. i use this local rom now..

im having an issue with 1.0.2 with su, it says su outdated but i cant get it to update it..

ok,, downloaded and installed latest su. 3xx through recovery

This post has been edited by gocke55014: Oct 6 2011, 04:26 PM

Please tell me. Wifi signal in these rom are strong as froyo 2.2 rom.
Most of 2.3.x rom wifi is weak (don't catch wifi quickly and signal is very weak.
Is this rom different with another 2.3.x rom ?

PS: i am using phantom sky froyo rom.

This post has been edited by minhduc5005: Oct 6 2011, 04:31 PM

Hi All,

I've been using FROYO Phantom Sky Fish quite some times. It's a stable ROM but I believe it is time to move on to GINGER BREAD since all LG, Samsung, HTC, etc already on 2.3 and I heard alot user commented 2.3 improve alot on smoothness UI.

May i know this new MY GingerB ROM have inherit some of the features from Phantom Such as

1) Can support 32MB java heap size
2) A2SD = which allow auto mount to ext3 mount point created on SD CARD. This is a cool features can allow us install APP on the fly without use move to SD.

Hope to hear from you guys soon.

Yes, i agree. 2.3 gingerbread have smoothness UI. I Tried some 2.3 custom rom from cyanogenmod kernel. But all of them have problem with wifi as i say above.
So i hope angelictears can mod a custom rom to fix that .

This post has been edited by minhduc5005: Oct 6 2011, 05:16 PM

I've stated it as a bug, like in the OP, I've said that you can delete the /system/bin/su file either from adb, or the ROM zip, before flashing the rom that is. Installing Su via recovery is also ok


I've tested and the Wifi signal is great, I've tweaked the fastauth code so it will reconnect to remembered network as fast as Froyo rom, if not better. The mygingerb is also optimized for Malaysian mobile network such as DiGi, Maxis and Celcom. Meaning that the signal will not fall below 3 bar in city area

MyGingerB are set to use 32mb as Java heap size as default, and can go as much as 48mb if users want to.
As far as App2EXT, the Rom does not, while this rom, same as any other Cyanogenmod based rom, will support App2SD, but not on partition. It also support automatic app moving based on your remaining memory that are free. Notification are also enabled to notify users on which app to move and which you won't. Although advance users can install script enabling App2EXT.

Hi,

Do you have the way/steps how to enable App2EXT for your GingerB ROM can share with us?

You can always use S2E (Simple2Ext), you can find it in the market, or click here
Or you can use darktremor's script found here, although some report mixed result. here
I recommend a full backup in case anything happen
I do recommend class 4 SD card or above.
As for the support, I will eventually implemented the App2EXT script on the next release.

Hi,

Thanks for the information. Then I'll wait for your next release which included this features. Carry on your good work...

i prefer and would recommend s2e. simple to install and use and btw, salute and many thanks to angelictears for responding to all inquiries with very detailed explanation. hoping to learn more from TS.

I already flash my CSL MI300 using "MyGingerb-1.0.2stable", but after reboot it stuck, just appear white screen..why this happen? can anyone tell me?

sorry my bad english :-)

Hmm, can you access the recovery mode again? If yes, try reflash the ROM, be sure to wipe data, cache and dalvik cache if you haven't

If you cannot access recovery(which is seldom as mygingerb flashes recovery as precaution), you can always use adb / fastboot to flash a recovery boot img, and boot back to recovery.
The simplest way is to flash any 2.1 (stock or firetrap[recommended as it is pre-root] ) and boot to recovery to attempt reflashing. Again with data, cache and dalvik wipe.

Good luck bro

bookmarked this .. and will flash later, but the problem is i nvr flash to cynomogen before.. isit still using SUTLR?

COOL ~ Looking forward to test this rom

It is uses clockworkrecovery to flash, much more simpler than SUTLR in my opinion
You can find some basic steps on the first post. Good luck bor

Thanks for the support bro
feedback are always welcome.

its working after i wipe data..thanks! but no signal in my phone..do i need to use Stock 2.6.35.11 CM7 kernel update and Latest Google apps?

flash to spice 2.1 first to retrieve ur imei back.. than flash with this one..

finally..

feedback:
1. needs ad blocker
2. the default gps server is europe.pool.ntp.org, as this is a malaysian rom, why don't set it to my.pool.ntp.org.
3. if can integrate google apps into rom on next release that would be gr8

Thanks for the suggestion bro
Will include all in the upcoming 1.0.3, for now, still finishing the custom kernel for this rom, at the same time finishing my college's assignment
Anyway, there will be moderate progress from now on, bear with me.

Hey, help spread the word to other mi300 users, or even consider donating
It will mean a lot bro, thanks in advance and for the suggestion bro, forgot about the adblocker

camera driver is great.. pics r looking a lot better compared to other roms.. btw, how to set gps server manually??

will be download today.. tired with wifi prob at cm rom..

need open etc\gps.conf
edit with text editor

Use RootExplorer® easier

https://market.android.com/details?id=com.Double.FasterFix
to set gps server
for those who lazy to korek their dir...

what is the best ad blocker?
gonna get rid of the ads

Thanks for the feedbacks guys.

1.0.3 stable is on the way promising more stable experience for those who planned to stay on one (latest) android experience for everyday usage. (And yes google apps are included)

1.0.3 (coming soon) will feature :

- Ad block, (some might debate on this as disabling ad are wrong partially)
- Featuring SuperAOSP 8.6 AW kernel (better battery life)
- GPS server asia.pool.ntp.org set by default (as there are users from thailand and other SEA countries)
- Better RAM management script included
- Faster GPS lock in, balanced between speed and accuracy
- minor stability fixes.
- more to come.

thanx bro

waiting for this release and im promise to be download..

same here

Boston-mania should post your rom there
