[Q] Latest stock & CM ?

Hello everybody. I have a i9100 with pda: xwlpy, phone: xxlq6, csc: neelp6 on stock 4.0.4 and Dorimanx 5.92 kernel.
Untill now i didn't want CM because of the dialer (really like the Samsung dialer) and other small things, but now i want a clean, fresh install and start.
So i was wondering, can I install this stock LSJ 4.1.2, then root it (or should i install it with mobile odin and try to keep root? i preffer via pc but root is a must), then install Dorimanx 7.26 kernel with mali and then as a second rom this CM 10 4.1.2 ? Then i'll switch dorimanx to battery mode because i'm not that much into gaming.
Are this the latest releases? Any advice before i start working ? (now i'm downloading for ages the stock 4.1.2)
You can root LSJ but not with Dorimax kernel.
You cant use dual boot option (yet).
Yes XXLSJ is latest release.
ok, is that 4.1.2 stock recommanded or another download

Click to collapse
that stock 4.1.2 is a leaked test version and not a official samsung release for u
hence try some other stable Stock ICS 4.0.3 versions for now, till a official JB released from samsung
hm... any eta for that ? that would be great but i'm afraid i'll have to wait some months and move to another country, so i'll have little access to a pc to get in download mode and everything to make a really clean install

i have 4.0.4 unofficial rom on my gs2, and i want to update my rom to x-tream rom (android 4.2.2) but all those firmwares are 4.0.4.
should i update firmware before i change to the new rom or it doesnt matter? could you please give me the link to a guide of how to update to latest firmware?
thanks in advance
You can update directly but emmc brickbug is present in 4.0.4 and you should update to 4.1.2 or downgrade to 4.0.3 then flash what do you want
Send from my SGS2 I9100 with HassanROM and latest DorimanX 8.xx kernel
sorry i didnt really understand, update rom or firmware, and what firmware should i use?
ROM = Firmware
Which firmware? Anyone you want, it doesn't matter.
You don't even have an I9100 do ya?

[Q] I9100P UK with kernel 3.0.31 -1246097

Hello,
I'm new to the android rooting scene, but I have a Galaxy S2 I9100P phone that I'd like to install a non-stock kernel in order to safely install CyanogenMod, as on the CyanogenMod wiki page for the S2, it states that it should not be installed on the stock kernel.
However, I cannot find a kernel that I think will be compatible with my phone. It is running 4.1.2 and the Kernel Version shows as 3.0.31-1246097.
Thanks in advance.
Which build version mate?
Look it up and then see Philz thread. You can find kernels for I9100P too. They can be flashed in stock recovery or via Odin.

I was wondering If it is safe to flash a 4.3 stock Firmware via odin on my I9300 4.0.4 device.It's baseband version is I9300XXLH1 which hasn't recieved any OTA updates so I'm going to flash one via odin.And I also wanted to know if any fullwipes will be needed after flashing new firmware cause for my I9500 which I flashed a 4.3 firmware on a 4.2 one I needed a fullwipe in order to fully boot the device...

Not sure why you want this as it's very old, official 4.1.2 is out, and we have all android versions available for our device from 4.1.2 to 7.1.1 in custom roms....any way:
