[Q] kernel downgrade for xperia arc s - General Questions and Answers

Plz.... Anybody tell me how to downgrade kernel to gingerbreed for my xperia arc s ... To make a official update of ics.. Bcoz I flashed my mobile before to ics. My mobile is still in warranty.. That's why I want to downgrade ... I think then its possible to make an official update of ics..

Be clear and dont talk like that, this isnt texting, its a forum. Anyway use a stock recovery tool/rom and flash that if there is one.

I recently bought an Xperia U tim branded phone
and i inserted an airtel sim in it and it just worked fine

Dont know wht's it for
Do u have any idea about it .....
And dude i really apprecieate your reply
Unlock bootloader is needed when u want to flash custom kernel. For example, to flash cm10 u need to use custom kernel. So that is the point.

The ROM Has Got Some Bugs And Hence I Want To Get Back To My Stock JB Rom.

You can use a recovery tool from sony to return your phone to stock. You can find the tool from sony official website, just download and install the necessary usb drivers and with original cable and internet connection you can return the phone to the latest stock rom available for the phone.
This always work. I have tried this with my lg nitro hd(P930) and Optimus 3D.

[Q] Changing baseband version of stock ROM

HI GUYs, it's me again.
Now we know we have Germany android 4.2.2 official
but the baseband version isn't our own country's
but i still wanna flash it to my phone without losing warranty
so..
is it possible if any developers change the baseband version of this stock ROM, without rooting or cwm and without further modification? like, only change the baseband version of the ROM and then make it look like my own country's ROM (the samsung guy only checks your root state and baseband version if i'm right) so if any awesome developer would make it possible, then it's beneficial to everyone who wanna flash the ROM, but don't wanna lose warranty)
so...
is it able to:
1) Change the baseband version without bricking or further modifying?
thanks
I think its possible but its hard stuff cause u have to change the radio.
And if u not 100% sure what u doing u will brick ur phone.

I don't know if it is a problem to flash a baseband from a 4.1.2 rom to 4.2.2??
But I think you lost your warrenty because it is a modification. Normaly there is no 4.2.2 rom for your country Samsung know your provider knows, so when you have a problem with the device an send it to repair, people know that there isnt't a 4.2.2 rom available but you have - maybe they don't accept the warrenty. So wait for 4.2.2 or have fun!
I w8 CyanoGenmod... now is in beta (If u have time try it)... U can flash 4.2.2 Deoxed is very cool FAST! (Flash is easy with odion no risk )

Flashing anything gives goes up and you have that bad fear that slows your heartbeat that it will fail or screw up. My phone memory is getting full and needs air to breath. Im baldly waiting for 4.2.2 to come for the None NFC version.
I'll load it with games then

[Q] is there any way to upgrade the android version on a device with locked bl?

Hi guys
Lately I have rooted my xperia mini and installed CWM using xparts. Anyways my bootloader is still locked and i'd like to upgrade it to 4.1.2 at least. So is there any way of doing that?
I'm using stock Ics rom and stock kernel.
If there are custom roms available for your device,you could flash them with cwm

Isn't it impossible to flash costum roms on a locked bl
device? I was kinda wondering if I could flash a stock sony jb kernel. Could that work?
If your cwm is for locked bl.. Then there shouldn't be a problem to flash a custom Rom. The Sony kernel your talking about should be supported by your device. I advice you to check your device forum
Pressing the thanks button is better than typing it.. Be Lazy Think Crazy ?
