[Q] Restore after flashing JB - issues - AT&T Samsung Galaxy S II SGH-I777

This is my phone:
Model: Samsung Galaxy SII GT-I9100
Android Version: 4.0.3
Baseband Version: I9100XXLPS
Kernel Version: 3.0.15-I9100XWLP7-CL340913
[email protected] #3
Build number: IML74K.XWLP7
I've successfully flashed the "leaked" JB 4.1.2 ROM on my SGSII, just to see if I could do it - and then restored it back to ICS 4.0.3, with all my apps and data intact, using CWM recovery. While I had JB installed, I found that I couldn’t enable USB debugging, which made me nervous, as I know that a number of the utilities I’ve been using require it.
So my questions are these:
1. any ideas why USB debugging wouldn’t switch on, and what could be done about this?
2. if I were to do the JB thing again and keep it this time, could I use the same rooting mechanism that worked on ICS, and get all the apps and data restored - but this time running under JB? The package I used went by the name CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5 – it includes CWM Recovery.
3. or if not, what is the best way to restore apps and data in this scenario? I really, really don't want to have to restore all my apps and data one by one when I upgrade my phone.
Of course I could just sit on my hands and wait until the official release.... Where’s the fun in that?

You'd probably be slaughtered alive for posting this question. This is xda, mate. Search, read and try before posting questions. And even if you do have to post a question, find the correct thread for doing so.
Since you asked, look through this thread for all your rooting requirements. Me and probably a million others like you have read that and then managed to root their phones following the steps mentioned there.

Dont forget to thank the contributor.
Yours being 4.0.4 theres a problem with an EMMC bug bricking the phone. again, read the forums thoroughly before going ahead.
Just flash a pre-rooted kernel.
I guess there is a thread discussing about rooting.

Swyped from my Samsung Galaxy SII
I have the same setup as you so I think you can look into my thread which i started yesterday and Jokesy took the time and answered all my questions there including linking to a guide (thank you Jokesy, fantastic). I did not use Odin, but i used CWM Recovery Touch.
After following Jokesy link i rooted my phone, i installed the latest siyah S2 kernel (no beta), i also installed Titanium backup and purchased the PRO key. After that i followed an external link of services and programs that i could safely freeze/delete.
It shall be said that i have been using SGS2 since last spring/summer and this was my first time modifying anything with the phone.
Here is my thread: http://forum.xda-developers.com/showthread.php?t=1841641

For simplest root just use method 1 from 1st guide in my signature. No CF-Root, no CWM needed. Just copy one file to external SD card and update from stock recovery.
- Thanks for the contributions... - there's a lot to take in -
- This 'Bricking Bug' is something of a concern... - so I'll be doing some more reading before I choose whether to proceed with rooting my SGS2 -
- Hopefully things will be simpler with the Nexus 7... -
- Understanding the various versions, terminology & methods etc. is giving me something of a head-ache today -
- But thanks again... -

different basband?
Hello devs,
I ran into a problem few hours ago and I am trying to work my way around and through it. I honestly did, I have already lost patience and feel like quitting life itself. I wiped my phone, installed a different BOOTLOADER, different MODEM, different CODE and different CSC. I did all this to install a new ROM, I didn't like the changes so I went for my backup and restored it. Everything was successful, except that the Baseband version hasn't changed at all.
What is a baseband? Does it matter if I installed a different one (it is supposed to be XXLPS-I9100)?
Thanks
Baseband and modem are pretty much the same thing mate. You don't need to have a particular one. If you find your signal isn't as good as it should/used to be, you can change your baseband at a later stage. It doesn't matter if you stick to the one you have. It won't spring up at night and chop your phone into two bits

Hey i have a problem my samsung galaxy s2 is an indian version 4.0.4 and its baseband version is I9100 DDLPB so its ok to root it with another baseband verison?

[Q] How to get my SII back to stock so Kies i can get OTA updates again?

Hi,
had my S2 for a while now and installed ICS through ODIN as here in NZ the updates seem to come a little slower than the rest of the world!
but id like to be on Jellybean and heard so much about unsafe Kernels etc (most of it goes over my head haha)
but i figure my best option, as i dont want a bricked phone, is to go back to stock and get my updates the old fashioned way.
what is the best way to do this? i know other phones can do this through KIES itself...(entering a serial etc), does this work with all phones?
any help would be greatly appreciated!
ICS 4.0.4 stock kernel has brick bug. If you are on stock 4.0.4 then avoid any kind of wiping. If you want to flash official JB go here
Hi friends I own Galaxy s 2 i9100....I got it from UK 3 mobile.. After coming to India I have flashed it with a ROM which is unlocked version as its is locked to 3 network...after the flashing I connected it to kies for backup and found the same message as others in this thread mentioned...so I tried reflashing it with a ROM that is compatible with Indian version and got the issue solved ...I am providing the details of the rom now I am using
PDA: I9100XWLQ2
phnoe: I9100DDLPC
CSC: I9100ODDLPD
BUILD info: Fri oct 26 16:04:15 KST 2012
But recently KIES software in my laptop got updated and when I connected my S2 it stated that my phone is not compatible to update from KIES. But, the same day when I connected wifi in my phone I got a message that an update is available and its done successfully.
Now can any body help me to get that issue sorted out when connected to KIES as it accepted before and now why it is not accepting ??
Thanks in Advance

thankyou! very helpful...now that i have read that entire post i just have one question....isnt that still classed as a wipe? the first thing it says to do is put your phone into recovery mode then wipe?
Flash Siyah or Dorimanx kernel first (without wiping ANYTHING). Then use the CWM that is installed with either of those to...
A) complete the wipe processes. And
B) flash your chosen stock ROM.
When you flash your ROM, you WILL overwrite the Siyah or Dorimanx kernel you previously flashed as your ROM has its own kernel (and CWM). As things stand at the moment, this is probably for the best because there have been some changes to CM10.1 that have made a lot of standalone custom kernels incompatible with the ROM..... for example, I lost my baseband when I flashed Siyah on top of CM10.1 and I'm told that there can be issues with video recording too. Which brings me to make one more point....before starting any of this...
MAKE A NANDROID BACKUP....
it's your safety net if it all goes wrong (personal experience is a brilliant teacher lol).......

[Q] Installing a Jelly Bean ROM on an unrooted ICS Galaxy S2 device

Hi everyone : )
I have an unrooted ICS galaxy s2 device and I wanted to install a Jelly Bean ROM similar to the stock. After a little bit of search I think SuperNexus 2.0 is a suitable one, however I'm open to other recommendations.
I did a little googling but I am still confused, as I am new to this whole process and I fear bricking my device.
My inquiry is: If you could provide me with detailed steps, or point me out to useful links that are targeting my problem and would show me how to carry out this operation, that'd be great : )
Device Info:
Device type: Samsung Galaxy S2
My model number is GT-I9100
I've updated my OS to Android 4.0.3 using Kies.
With kernel version: 3.0.15-I9100JPLPF-CL644992
Build number: IML74LJPLPF
Update:
gatsonw suggestion was right on the spot (Y)
The steps I carried out, for others who had my issue:
1. I rooted my device using Odin to flash Siyah v5 Kernel
2. As a precaution I downloaded Titanium backup and made a full backup
3. Also, I made a nandroid backup of the device as well and copied it to my PC
4. I downloaded SuperNexus ROM from the thread I already pointed out above + google apps for Jelly Bean and stored both of them on my internal SD card
5. I made a wipe/factory reset of the device from recovery mode
6. I installed the SuperNexus ROM then the Google Apps from the internal SD card, also through recovery mode
7. Rebooted my device and enjoyed the new ROM

Don't worry, follow the steps on that thread and you'll be alright.
The only thing you have to do is to root your device and flash CWM, your best choice is flashing siyah kernel (it'll get you rooted & you'll have CWM).
Where can you find siyah v5? gokhanmoral.com

[Q] Returning phone to stock URGENT HELP

Hey guys,
I have to admit I am not too familiar with phones, roms, rooting, un-rooting etc.
Thing is my friend rooted my girlfriends phone and it has been playing up ever since (2 years)
Today I decided to return the phone to standard because with the current root/rom it will not let me update android from ICS to JB.
I backed up as much stuff as I could and then powered the phone in the basic mode and did a factory reset.
Phone starts up and it still has the old ROM on it only with out all the data apps etc.
I read I could load a stock rom with Jellybean on it to get the phone back to standard.
I have a list of samsung firmware's but my phone is not on the list I would post the link but it won't let me because I am a new user.
Here are my phones details.
Model number - GT-I9100
Android Version 4.0.3
Baseband - I9100XXLPW
Kernal Version - [email protected])
Build number - Lite'ning ROM v3.1
Region - XEN
If I use any of the others will this brick my device? Is there any way around this?
Please help. My girlfriend needs her phone asap!!!
Thanks,
kizbot

Samsung gave up on that device long ago. Luckily the developers here did not. You should look into upgrading via a custom rom like CyanogenMod.
Basic steps go as follows:
Backup everything and save to the PC
Decide if you want to focus more on stability (JB roms) or cutting edge (KK roms)
Move rom zip you chose to the SD card along with the appropriate Google apps package
Install a custom recovery that will work with the kind of rom you want to install
Boot to recovery, make a backup, wipe everything needed, and install the rom and Gapps
*Probably have to install an updated modem depending on the rom you choose*
Reboot and enjoy
You'll find everything you need in the Epic 4g forums here on XDA. Make sure to peruse the Stickies found in the General forum and Developer forums.
