[Q] Flashing 2.3.5 on galaxy s2

Hey guys! I need some help from the community.
I want to flash 2.3.5 firmware on my s2, but I have a few questions... I live in Austria and I am on Tmobile. I flashed a 2.3.4 on it, so I partially de-branded the phone. However, I would like to flash 2.3.5 but it is not yet released for austria. I see there is a Polish version, but can I flash that to mine? If I do, will I lose network settings? Can someone give me a short guide on how to do this? I am confused on what does the CSC file do? Can I just flash the PDA, and the PHONE, without flashing CSC?
Your help will be greatly appreciated.
Thank you,
Mick

Get yourself the frankenstein version from this thread: http://forum.xda-developers.com/showthread.php?t=1075278
Choose one that will be "non-wipe" and follow normal odin flash instructions, flashing pda only.

thank you man I think I'm just gonna wait for android icecream sandwich to come out... this is not worth upgrading...

Hi thanks for the reply before i give this a go is ther any way of updating baseband via CWM.. and one more thing when i go to about phone will new baseband look the same as current or will it be named different ??? Sorry if this has been talked about already ..

There is no option to update baseband via cwm,this is only solution so far.
I'm on gb and my baseband name is same as yours,but you need to flash gb baseband obviously.
Cheers.

You can flash an O3d baseband to the thrill? If so, which baseband is recommended for a gingerbread flash?
Thanks!

i use baseband from official v21a gingerbread and it is workin fine for me,no ghost calls or something like that.
you should flash official gb for thrill and then search custom roms in development section for thrill 4g.

Please,please give me your help about v21b

[Q] Lg Optimus 3D downgrade

Hi. Congratulations on the work you are doing here. I have an Optimus 3d P920 phone. I recently upgraded to ICS european open version V30a using Lg flash tool and the guides from your site. My phone is Greek and only V21e exists at the moment. So my warranty is void. I need to take it to LG as it became very slow. How can I downgrade to official Greek V21e wihout LG understanding that I upgraded the phone? Please can you provide a step by step guide as I am a noob? Thank you in advance for your replies.

Thank you again. So I would like to have the ability to play with my phone's cpu speed etc. my phone is SU760. What rom should I use? Can I use stock rom V30a and use another kernel so as to perform some tweaks? Sorry for my noob questions. What is the best custom rom to use on SU760?

I've looked everywhere, it seems that 2.3.6 isn't available anywhere.

Thanks for reply.....
If we cant find old software then we have another way to get rid of that slow software..... I think by installing a rom we can get a solution.....
In this way i have a question that, for installing a rom bootloader must be unlocked?
If yes so kindly help me to unlock my bootloader.....
Another question is that, is there any software by which we can install rom on phone........
Thanks

You can try this for unlocking bootloader
www.unlock-bootloaders.racing/2016/12/lg-optimus-3d-cube-su870-4545.html
The software needed to install custom ROMs is called a custom recovery such as TWRP. When you get your bootloader unlocked you'll need to do a google search for:
"Custom recovery for (your model number)"
Or a search for:
"TWRP for (your model number)"
