Install CM9 stable - Galaxy S II Q&A, Help & Troubleshooting

Hello guys.
At the moment, I'm using siyah kernel 4.0.1 with dual boot of CM9 RC2 and slim ics (2ndry). Now I want to update from CM9 RC2 to the latest stable release.
Can I flash without data wipe/ factory reset and having all apps and settings still there?
Thx for reply folks!
Btw: great platform!

Yeah. there's a guide to dual boot with siyah. I believe you would just go to the dual boot settings in cwm recovery and flash the updated zip to the first/second rom.

Thx. Made an backup via cwm, then flashed the newest CM9 version. Everything went fine. I only had to reflash siyah kernel cause it installed the cm kernel while flashing.
Can be closed!

[Q] CWM touch recovery?

Hi, I've got a GSII, it has LPQ ROM and it's rooted via CF-Root.
It has a CWM v5.0.2.7.
How to install CWM touch recovery?
Thanks!
I'd recommend Siyah Kernel found here. Alpha 7 is the most up to date and suppots LPQ.
I saw that but I don't want to change my kernel at the moment...
From ROM manager....scroll to the bottom of the main page. It gives you the option to flash the touch recovery.

[Q] Flash Pershoots CM9/10 build wit TWRP

On his blog post, it says to use the packaged recovery to flash his ROMs (CWM 6.X.X.X) but I prefer TWRP. Has anyone attempted to flash them with TWRP?

I am on official ics now, but I flashed the July 29th cm9 build with twrp successfully. Don't know about the latest build though.

[Q] Just flashed Siyah Kernel on Omega Rom.. Gives black screen

Hey all,
I'll try keep this short and sweet. I just flashed Siyah Kernel 1.5.4 on my GS3 (currently running Omega v26) and it flashed fine, rebooted the phone and logo showed up all good. However, past that stage the screen goes black and I'm not sure if it's actually booted into the phone.
I can press the menu/back buttons and they respond, but nothing shows up on screen. I can also enter recovery/download mode, so I've tried reflashing the original CF-root kernel and still no luck.
Currently going to try a nandroid restore but does anyone have ideas what the case might be and how to fix it?
Cheers,
poopehz
You need siyah 1.6x for roms based on jb leaks.

Thank you Theshawty, this was it. I automatically assumed the kernel I downloaded from Omega Kitchen app would be compatible.. apparently not.
Appreciate the help.

Can't flash kernel via Odin

Hey all.
I tried to flash Siyah v1.5.3 kernel over official JB firmware via Odin 3.0.4 and after flashing I turned on device and heard boot sound, notification sound, capacitive buttons where on, but the screen was black and CWM didn't install. Then I installed CWM manually and flashed kernel via CWM and everything went fine. Maybe someone know what's wrong?

Just flash siyah kernel 1.7rc1 thats the kernel for jb
Sent from my GT-I9300 using xda premium
Use (dot)tar file to flash with ODIN and (dot)zip file to flash with Clockworkmod (Custom recovery).
And Siyah 1.5 is Ice Cream Sandwich kernel. Siyah 1.6.3 and 1.7.1 are both Jelly bean kernel. Use the latest kernel.
Oh, so I used wrong version kernel. But I thought that version works both with ICS and JB. Thank you guys!

Boot into recovery, wipe cache, factory reset and install the 13022013 nightly update (last 4.2.1 rom and gapps). It should boot up.

thanx a lot it worked!
Had same issue.
Does this mean that if you want to revert to an older nightly you can't use the ROM built in update functionality ?

If you do that you will likely bootloop as there will be file residues from the previous newer nightly. So it is better to flash the older nightly with recovery but you have to wipe before flashing.
