Steps to go from ICS to GB -custom ROM's - Galaxy S II Q&A, Help & Troubleshooting

Hi there!
As i have try to find info about downgrading ROM's with no success. (It's big forum indeed).
I have installed ICS XXLPH. Rooted and CWM-ed with Chainfire kernel.
If i want to install custom GB ROM's with CWM are there some precautions that has to be taken prior to go from ICS to GB?
Thanks a lot!
Brgds,
M.

You can just flash immediately from CWM with no problems, there are no actual precautions. However, you will need to wipe all of your data, cache and dalvik COMPLETELY before flashing because any ICS data will not be compatible with GB (otherwise, you'll just have non-stop crashing and force close issues)

Step 1 - use the search button

Reboot into cwm, wipe everything (data, cache, dalvik), flash zip - rom and reboot.

You may need to change the bootloader .

Use Odin and flash a rom(2.3.6) which have bootlader for example XWKK5.

[Q] CM9 to Stock ICS.

Can we simply flash 'stock ICS' over CM9? I mean will there be any probs?
I don't have an S2. This is for my friend. I tried to search for it but I couldn't find anything regarding CM9.
Thanks in advance!

Just try it and report back.
If you get bootloops, you may have to to a factory reset in recovery mode (press Volume UP + Home + Power until recovery menu appears).
Good luck !

Of course there is Stock ICS but not official one. The latest one that is released for i9100 is XXLPJ ICS 4.0.3 firmware.
Now my doubt is can we just flash it directly over CM9?
Heard from one of my friend that in 'samsung galaxy s' we cannot simply restore CM7 backup over CM9. Firsly we have to flash CM7 over CM9 and then we have to restore the CM7 backup.
For S2, downgrading to GB from CM7 is fine. But what about from CM9? Can we directly flash ICS or do we have to come to GB first and then upgrade to ICS?
Actually I would have flashed it yesterday itself but am just waiting for some replies. Till today night I am gonna wait and then I will flash it and reply here.
Just get the phone to download mode and flash with Odin. Yes it can be done
Sent from my GT-I9100 using XDA
I agree. I don't think there would be a problem flashing it. Just do a "full wipe" before.
Flashed the latest ICS (XXLPJ 4.0.3) and it is working fine. Thank you guys!
Was your data lost?

I did a wipe before flashing. So all data is lost obviously.
But generally whenever we flash any stock rom or custom rom all data will be lost, right?

It's complicated, but very generally speaking - yes.
I would still wait for a no-wipe cwm of the rom to see how compatible sammy ics and cm9 ics roms are

[Q] Help - TW launcher is not responding

Hello
After I rooted my phone, I freezed a couple of programs, and got carried away. Now twlauncher is not working. I've tried factory reset. But that didn't work. Now I am stuck at a screen telling me twlauncher stopped working.
I cannot do anything. I am using the danish version of ICS. There are to many threads on how to flash ICS. I have no idea which one to trust, that works. So I would really appriciate it, if somebody could help me. I am kinda scared/freaking out.
Thanks.
Hey. Do not worry. Have you got CWM Recovery installed in your ROM? Go into recovery mode and clear both Cache Partition and Then go into Advanced and clear Dalvik Cache. If that does not work i recommend you flash the most stable rom which is Litening ROM. I am using it for nearly a year and it is the most trustable rom.. Also installation guide os very well provided on Litening ROM thread.

Come on, do the work yourself. 290 posts and you can't be bothered searching?! Use the FAQs and stickies, that's why they're there.
You've given no info as to how you managed to bork TW launcher either. "Got carried away"... "freeze a couple of programs"... Very helpful.
For future reference - always handy to have another launcher installed for emergencies.

Don't know if there's a specific Danish version - not even sure if there is an official ICS in Scandinavia yet, never use Kies (I'm in Norway). Scandinavian firmwares have NEE as a CSC code.
Try Check Fus to find the most recent dansk firmware, then samfirmware.com for downloads.
Lykke til.

Here you go.
Edit - or did you mean the firmware file to be installed with Odin, not actually Odin itself?
If I were you, I'd worry about ICS later, and get stock GB flashed first - at least you'll have a working phone. Follow the guides jjegan linked you to.

[Q] Quick question regarding updating.

Dear reader,
I've currently been using Cyanomod for 2.3.7 Gingerbread.
My phone is rooted and everything (which took a little while )
Everything is running perfectly fine, but i would like to update my phone to android 4.0+ (whatever the lastest compatible version might be)
How should i go about this?
Do i basically uninstall everything and start from scratch or is there an easy method to quickly update my phone to android 4.
Kind Regards and Thank you for your time!
I believe the answer us first to backup your apps with titanium backup if you need them. Then go to recovery and backup your current Rom. (always be sure to do this). from recovery wipe factory reset and dalvik cache. Then install your new Rom from zip.
You cannot install an android 4.0 + over another version. Always backup and wipe.

Do i need to re-root my phone when i install a new Rom? Or should i just install it through recovery?
Rom's are pre rooted (expect stock, stock BASED roms ARE pre-rooted), once you've installed the rom through cwm, it will be rooted and ready.

If your bootloader is unlocked, you can easily flash a custom kernel (Based on ics, so it'll be compatible with ics rom) And boot into recovery, and flash a custom rom based on ics.
One last question, since i'm having trouble finding compatible roms.
Which one would any of you, recommend for me to use ?
I have a ST18i and i'd like the lastest compatible rom.
Thanks so much for the fast reponses and ofcourse the help.
Kind Regards,
Since you're using CyanogenMod 7 I would recommend you to use CyanogenMod 9.1 i.e. FXP 138 is the best in my experience.

If your finding trouble with compatible roms are you saying your getting bootloops when trying them?, because a different Android Version requires a different kernel, So if you haven't or forget to flash the kernel recommended or provided then that would possibly be where your compatibility issues lye as you will get bootloops if you don't and you are changing version. As Mikii suggested earlier.

Ahhh that must be it then.. I've been using the same kernel for quite some time now because it was quite a hassle to flash it. Different roms come with different kernels (at times). I'll have to figure out how to flash kernels again. Gonna check around the forums to see if i can find a suitable thread.

The fastest way to flash a kernel is to use the program called flashtool, click on the lightening bolt, select Fastboot mode, then select kernel to flash find the kernel you want to flash and it should be done within literally 2 seconds. once Flashtool gives you the all clear, disconnect your phone from usb, restart phone, and there you go, the old kernel will be overwritten, and so will that kernel's cwm version, with the one from the new kernel.
Try FXP138

Hey,

Whenever i reboot my phone i get, right after imputting my sim code, a Unlock Network SIM message.
What is this and how can i solve it?

Question about superbrick and upgrading to Cyanogen!

Hey everyone,
Sorry if the Answer was staring me in my face but I'm not sure about upgrading to the CyanogenMod because of the superbricking I might get..
If any help can be given as to whether I am safe to do it, it will be much appreciated, My android version is 4.0.4, Build number imm76D.XWLPT.
I have just rooted it with XWLPW-ROOT-CWM6, and It seems to have rooted fine.
Will be much appreciated if I can get any help as to whether I can Flash it with CyanogenMod and everything will be fine..
Thanks again
EDIT: Yeah I just realized about having the Superbrick bug, I must have a kernel that is not liable to bricking, I rooted it with PhilZ touch 3 and when I go into recovery mode it says CWM Base version: 6.0.1.8 at the bottom, Am I safe from the bug?
You're safe as long as you don't perform a wipe from stock recovery in 4.0.4 (and not all phones have an insane chip). So yes, you can flash CM.

EDIT: Sorry, do you know which CyanogenMod I should flash? I just want to upgrade to one that is fully working, but there are many in the index and I dont know which one to flash :s THANKS!!
and If I dont do a wipe? wont it be stuck at boot as the Guide says it will?
I highly recommend you read the discussion thread for the version of CM you're wanting to try in General section. So you can get a handle on other people's experiences with it, bugs/flaws/annoyances/features/etc. I never flash a rom without reading the first 10 pages of those threads & the last two weeks or so worth of posts so I know what I'm in for.
I agree. And you always have to perform a full wipe if you change firmware.

I assume you've read guides about how to flash a rom? Copy the zip-file to your phone, back up, wipe and flash.
You don't have to be scared of this superbrick bug because you're already running a custom kernel.

That's what I am so confuzzled about, I need to downgrade to a custom rom that must come with a custom kernel right to be able to upgrade to cyanogen right...? otherwise ill brick it?
No. Make sure you flash a custom kernel (for example Siyah) with Odin. Then there's no need to flash other firmware first before upgrading. Just wipe your device in CWM (after the back up), and flash the rom you want.

Make sure you have kies installed or at least the drivers.
Reboot into download mode
Run ODIN 1.85
Flash Siyah kernel (.tar) via PDA section
Boot into recovery run backup
Wipe data/factory reset
Flash CM zip file.

Btw, if you have any apps/appdata you need to restore after wipe you can restore them from your nandroid backup using appextractor.
