New development blog launched. Check it out here for full updates.



MYGingerB is a project of our very own Gingerbread Custom ROM for MI300 (and other Commtiva z71 clones).
Based on current Cyanogenmod source, it aim to be more user friendly, stable and faster for everyday usage. The ROM is built under Linux (Ubuntu 11.10 32bit) environment, coded using Eclipse under Java Development Kit 6.
Maintain by myself. Other developers are welcomed to joined as well.

Release notes Gaia 2.0.x Beta 2 (note to change)

Notes on things to do after flashing :

If you still have touch screen problem during first boot, try rebooting, if not reflash the ROM via recovery WITHOUT wiping the data, cache, dalvik and battery stat.

Please go to Settings -> Application -> Development
and untick USB debugging and Allow mock location to ensure normal usage.

Attached thumbnail(s)

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

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Gingerbread allows more optimization for ARM platform, especially ARM6+ where Froyo are still better then Enclair but outdated in terms of CPU management.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.

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

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

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?
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

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.

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..

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

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.

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

Thanks bro
It is safe to say that it sells from rm480 to rm500 retail,without promo. Other members will have an accurate answer for that I believe

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.

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 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

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

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

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
