I just flashed JB 4.1.2 and im having a hard time rooting it.Is there different steps for JB? I've searched and can only find steps for TWRP but i have CWM installed. any help? sorry for being noobie

What do you mean flashed 4.1.2 ? Did you flash a rom? If you did, it should already be rooted

If you Odin flashed it just Odin flash twrp 2.5.0.0 and apply root when asked

Airplane Mode

Hello everyone, this is my first post here
I have a frustrating problem. Yesterday i update my Galaxy Ace 2 from 2.3.6 to Unofficial Cyanogenmod 10, everything was good.
But on first up i get A LOT of "radio has been granted superuser permissions" and i saw that i dont have any GSM signal.
Anyone knows what i do wrong?
PS. I also have a problem with Airplane mode, i just cant turn it off.. everytime i try its getting ON by itself.. ofcourse because of that i cant do any SMS and Calls (and maybe this is why i dont have any signal).
Please, help me.
Sorry for my english

Have you installed stock samsung JB before installing CM10? You have to do it before installing CM10/10.1.

No, i install CM10 on stock 2.3.6. So i have to flash samsung JB first?

Yeah, you basically flashed a whole new android version that was completely different to 2.3.6, get Odin, flash the latest 4.1.2 stock firmware, root it, then get CyanogenMod again

Okey, i will do this.
Can i use Heimdall (linux) instead of Odin?

The different Android version isn't the problem. On my old Xperia X8 we had officially only Eclair and all the custom ROMs (CM6, CM7, CM9, CM10) worked without problems. The problem here is that Samsung most probably changed some stuff in modem in the JB update (and hence the RIL doesn't work when you install CM10/10.1 on top of GB).
@derester: Yes, if you know how to use it.

Thank you guys!
It worked .
It was loong road to get it work, but im happy now

[Q] Downgrade from KK to B125

Hello everybody,
I have a problem while tring to downgrade from KK to B125. Whenever I try to flash B125 via stock recovery it stops at 'checklist module VERLIST ... FAILED'
Did I forget anything? What am I doing wrong?

Try flashing through force update (press power+volup+voldown to boot). If that doesn't work, redownload the file and try again.

I already did it that way - force update. And I don't think redownloading helps, because I know the files are okay, because I already used them before. But I will try that. Nobody knows, but sometimes it's strange.

First of All u should have stock recovery..
Then as u have stated if u cant downgrade to b125 then first do factory reset and then reflash the KITKAT firmware.
Now try to install b125......OK.:thumbup:

Hi!
From where should i download stock recovery ... ?
I am on KK firmware ... but cannot install B125
Any tutorial how to achieve that?
Thanks!

I made it working. The only thing I changed: copy the update.app via stock file manager to /dload on sdcard. The times before I used ES File Explorer.
No redownloading was necessary.

[Q] stuck on bootloop when upgrading to ktkt

hello guys need some help here tried almost every solution on my ascend p6 U06 when i was upgrading it to ktkt. the device wont start and i dont have a rom back up or stock recovery tried reverse it back but nothing changes. it can only boot by/frm bootloader and recovery mode. and the adb commands does not work only fastboot. current using PC OS w8.1 can it cos the adb command not to work..? and how will i brick the phone to life.

If you can go into the recovery then you should be able to install a system. Try downloading one of the stock firmwares on the forum and follow the instructions on how to install it
