ROM Manager is not fully compatible with SGS II - still some bugs. If it is good, I'd have highly recommended it in Page 1. Not only me, ,many XDA'ers will propose to use it
When you use Rom Manger, first thing it will change your recovery on phone. Than depending on your rom type, kernel - when you try tyo backup - it will fail. And assumimg you can backup, most probably you will get a fail restore

When we want to use a backup/restore program , what is important you mjust have a 100 % good backup and a 100% good restore. There is no in between both must be 100%. Anyway you can try if you wish and please update us if you are successful

I suggest you :

1. Use Titanium Backup to backup all your apps/data
2. Use Odin to flash Chaimfire CF4 - this will root and install a Clockworkmod recovery
3. Boot to recovery and select backup
4. Than only proceed flash whatever rom

I am using it back then. Now, kinda miss it already. Miss the reboot button

Get the app called 'Quickboot'

Tx for the reply .... Ya .... Balista 2.0 > Cog 1.11 doesnt give prob ...... Balista 2.0 > Lite'ning 2.0+2.1update > Cog 1.11 gave it ....... All the while was running on Chainfire kernel ...... Anyway , flash back stock rom as it gives the best batt life for me

hi, i am new to this forum and my friend recently brought me in here to learn more about the phone i recently purchased. my previous phone is pretty much a dinosaur and after reading what is on the 1st page, i felt somewhat even more confused.

can one of you please explain to me what root is ? it is way too technical for me to understand. how do i get the galaxy s2 to play encoded divx files ? can i hook this up to a projector unit and display it ? what kind of resolution would i be looking at assuming i have a sxga projector. will it be able to handle and beam out at the maximum resolution the projector can take ? what special cables or devices would i be needing and at what price range would i be looking at ? will this be a pal or ntsc system setting ? am i able to view photos shot in raw format ? and more importantly can i beam those out onto my projector for presentation purposes ?

is there any free software that i can use to do a group chat ? or is it bound to the service provider ? something sort of like video conferencing for mobile phones but not a 1 to 1 session rather a 4-5 people session.

the reason i bought this unit was that i was initially very impressed with the tablet computing power and my friend told me this is by far more powerful and faster than an ordinary tablet minus the screen size. so i thought that maybe for mobility purposes for presentations i could use this as a replacement to a laptop or a tablet as it is lighter and easier to pocket around.

thank you.

Just flash the mod in recovery but before you do that read the thread and make sure your firmware is supported

What? How come mine were removed after flashed to stock kg1, both root and cwm gone. i downloaded the firmware from link at page 1. And, i just relized when i plugin to usb now, my phone did not connect to Kies. Kies keep on "connecting" no end.

Thank you

Yes sir uncle Benny! Anything I dunno I PM you /gg

Then just go to download mode, use Odin flash Chainfire4 ( KG1 version ) to get back root and CWM

Bcoz its not rooted any more.. u are at stock rom..
just flash CF kernel n u will rooted again..

the KG1 is not official release.. it's a leaked..
so kies will not recognize the new firmware..

But i feel there is something not quite right...sometime pc cant recognize my phone. sometime it dun appear in odin.. is it ok if i do repartition if i re-flash stock xxkg1? I want to turn the phone back to factory condition since kg1 is good enough for now. is there any specific method to completely remov everything and restore fresh official firmware?

YES you can do repartition - your internal SD card will be wipe completely clean; so backup any important stuffs you have - eg your games data, newsfeed/rss feed, etc . After successsful reinstall, just manually copy back. What I usually do ( lazy method ) I just copy everything over to my hard disk and than copy back everything ( except the folder Android, lost.dir, temp as these will be recreated back when you reinstall or restore apps)

Thanks benny for prompt reply.. will do repartition. my phone still empty anyway, not worried to loose anything.. btw, to do repartition, i need to use the pit file during flashing, am i correct?

Is it before using Titanium backup, need to use superoneclick to root first, then follow the steps listed by you?

Thanks uncle beney. Helps much. I hope to write this up, it will help me understand these things and perhaps might be useful to other newbies.

ive tried last night with villain rom..and trying to put custom status bar,CRT effect and power mode button..but still cant get it right..sometimes the status bar did not shown..then i flash cognition and done..

People do it to the iPhone. Why not the SGS2?

Sigh, if people wanted long battery life, they would have gone and gotten something archaic like a Blackberry. If people wanted a balance of everything and CAN live within a walled garden (and the fact that it's practically made out of glass), they would have gone and gotten the iPhone 4.

The list goes on. EVERY phone has it's issues. It's all about compromises.

I got the SGS2 simply because it has OTG and I was dying to try a dual-core robot, to see if it's as MARVELLOUS as everyone said it was (which it is not, really. It's good, but right now you don't really FEEL the sheer power of a dual core).

BUT, with all that being said, Samsung SHOULD have made the entire back level, they could have AT LEAST fit a 1800-1900mAh battery in there if the battery compartment was level with the hump on the bottom back - which would have meant 2-3 hours more of screen on time.

You are right. You will need to root the phone first before you can use Titanium Backup.

uncle benny, i have flashed to Litening ROM 1.5 and shortly after that i downloaded the tegrak overclock ultimate. Now i am trying to set the core voltage down to 750mV at all levels, but after i set at CPU level 4 (i started with this one first), my phone keeps vibrating and buzzing. it says.. watching stability.. am i doing it correctly?

Please i need help..

Does the 300sec timer doing a countdown ?

nope i dont see any countdown.. still buzzing as i am writing this.. oh no..
