[Q] How to install CM10 rom if currently on leaked stock JB? - Galaxy S II Q&A, Help & Troubleshooting

Hi.
I'm currently on stock rooted xxlsj JB (with philz kernel) and I want to go back to cm10. Is there any special procedure to do that, or do I just make a full wipe and flash rom normally?

[Q] Will it be safe to flash stock rom with unlocked bootloader and custom kernel?

Hi guys,
I just wanna ask, when on a custom rom will it be safe to flash any stock rom (2.3.x or 4.0.x) with a custom kernel?
Will I have to flash the stock kernel too with the rom?
I have never tried but I think it's absolutely fine to do it. Go ahead and give it a try.

Upgrading from Custom 3.1 rom to Official ICS

So last year I got my tablet and used TASK650's Paris custom rom. So far no issues but I want to finally upgrade from that to ICS or even jelly bean if its available. What is the safest way to upgrade? Should I first go back to stock and go through the offical OTA updates, or download a custom jelly bean rom developed by another person.
It sort of depends on whether you want stock ICS, CM9, or Jelly Bean. If you want to flash a Jelly Bean ROM from Honeycomb, you may only need to upgrade your recovery. Go to the following site http://droidbasement.com/galaxy/roms/cm10/p4wifi/ and download the "recovery.tar.md5" (that is CWM Recovery version 6.X.X), which is what you'll want before flashing a 4.1.1 ROM. Just flash the recovery via Odin then you should be OK to flash the ROM. Report back if you run into a problem.

You are joking right?
Have you tried this CM9/
Neo
Neo V
Its the OFFICIAL STABLE cyanogenmod for the NEO. It is VERY STABLE and has everything working.
Apart from that, to revert back to stock, just flash a stock kernel (Or any modded kernel for stock) and restore the backup you made before flashing the cm9 rom.

The roms that you have suggested are for "neo". i am using "neo v" and the reson i wanna go back to stock is because i con not onnect to my gmail account with cm9 over data connection. Its giving me some sort of an error: can not establish reliable connection....."...
now for going back to stock ics can i just flash it via cwm and i will be back in stock ics? dont i need to flash karnel or anything like that?

I just added the link for the neo v
Yes, you need stock kernel.(or modded kernel for stock roms)
The kernel for CM will not work with stock rom.
My suggestion is to try the stable cm9 for neo v from my link. If you are still unhappy then download a stock kernel, flash it it fastboot then restore your stock backup in recovery.
Do remember, if you flash stock kernel you will have to install a recovery. Or you can flash the alliance kernel from this thread

Rule number 1
Always backup, just in case you **** up!
Anyway, no problem, there are several options.
Find a stock .ftf in the dev section and flash that in flashtool after you have flashed the stock kernel.
Or, repair phone software using PCCompanion.
This will revert your phone to factory settings (Out of the box).
Or just follow the instructions in any "stock" based custom rom. I recommend Ice cream Pureness. Its a very good stock ICS based rom, fully functional and stable

[Q] Reroot S2!

Hey!
I rooted my friends S2 alooong time ago, it's on Android 2.3 with Cyanogenmod.
Now he's starting to have problems, it says that the harddrive is full, but it isn't. And now it won't boot up anymore.
I'm going to reroot it, how am I going to do? It already got fully working recovery, but it's old.
I got some questions:
*He's stuck on booting logo, can I just flash an 4.1.2 ROM over the 2.3 Cyanogenmod ROM? Will something happen?
*Do I need to update the recovery? How? As I can recall, rooting the S2 was a huge problem for me. I didn't have the same problem when rooting my S3.
Thanks in advance,
Sebastian

What do you want to do?
Update to JB 4.1.2 (XXLSJ)?
Then flash stock XXLSJ ROM, or (like me) XXLSJ NeatROM Lite v4.0, which is modified stock ROM (removed bloatware and some nice mods added).
NeatROM is already rooted, so no need to root manually.
Here is the NeatROM thread => http://forum.xda-developers.com/showthread.php?t=1569686
I recommend to do the full-wipe install as described in the thread.
You only need CWM recovery for flashing the ROM zip file.
If you want the stock ROM (flashable as tar file with Odin) and manual rooting, then use PhilZ-cwm6 kernel v3.65 for XXLSJ from here => http://forum.xda-developers.com/showthread.php?t=1877270
Just download kernel zip file and flash it in stock recovery (after flashing the stock XXLSJ ROM).
Good luck !

Well, I'm wondering if I just could flash latest Paranoid ontop of the 2.3 Cyanogenmod, would that be possible? And do I need to flash over Odin, or can I just put everything on my SD card and flash via recovery?
