[Q] Can i flash Jelly Bean on my XPeria Arc S no bootloader
Is it possible to somehow change my android from ICS to custom Jelly Bean on my phone
Sony Xperia Arc S LT18i, Production date code 12W22
It came up with Android Gingerbread on board.
What i did so far is using program called Flashtool to flash my phone with stock Android ICS 4.0.4 4.1.B.0.587 (the file was called Android_4.0.4_LT18i_4.1.B.0.587.tft). This replaced branded Gingerbread with non branded stock ICS
After that i used Flashtool to flash my phone with Kernel 4.1.A.0.562 and then i used DooMLoRD_v1_Xperia-2011-ICS-ROOT tool to root my phone.
And after that i flashed it with 4.1.B.0.587 kernel.
By doing this steps i supposedly achieved root on my phone (superuser and root checking apps show full access).
Now i read about flashing with Jelly Bean custom roms and all i seen mention "bootloader"
When i open secret service menu on my phone there are two things that worry me:
- Simlock - it says my phone is provider locked
- Bootloader unlockable - NO
So this is my question, is there any way in my current situation to somehow flash my phone with android Jelly Bean? In a similar way that i used to upgrade it from gingerbread to ICS?
