I don't understand the question - when wouldn't it boot and why would IMEI have anything to do with that?

You should be able to go to official ICS (without using hack) from b892 - always wipe caches factory reset BEFORE installing ICS

then save the original IMEI and you will be able to use that to downgrade any bxxx rom

NO boot (we are talking about ICS here?) Boot into Android recovery by battery pull/ back in + hold volume up into Android Recovery (NOT CWM) and wipe the cache / factory reset and reboot and it should boot

The hack only allows the rom to bypass bootloader check to load it ..... the version of rom applied by update.app will always be official and untouched

No, it allows you to flash any update.app of any version. It serves no other useful purpose.

if we update to ICS Chinese when another version of ICS appears we need downgrade ?

was wondering that too. I think you might unless it's a higher version.

Seems you guys discover new things by the hour. Hope the guide and instructions in the first post will be updated to reflect those findings. It is hard to keep up otherwise.

I think I might start maintaining a FAQ on Google Docs. Easier to update it that way.

If the ICS is a higher version of boot loader i'm hoping it should update without this hack

with the Uk version of ICS you may need to run this hack again - I can see No reason why the UK version of ICS would not be able to be flashed to replace chinese version

Yeah, tried this, still the same chinese splash1 screen. I see the root shell appear and I know the bootloader is unlocked because I have flashed a recovery. I don't want to keep running the unlocker because surely that can't be wise. Guess I'll just wait until someone works out a manual way to do it - I know fastboot flash splash1 works on some phone as I used it on my HTC but don't think that works on the g300.

Edit: Bah, I dont get it. I just re-flashed ICS via the dload method so the bootloader got re-written, I then used the newer english bootloaderunlocker.exe to root & unlock but I still have the stupid white /orange splash1 logo. I wonder why I can't change this logo... :huh:

2 possible causes either you haven't restored your imei as this removes chinese splash or

I think what ever splash screen you have when you make imei backup is replaced when you restore > so if you make a imei backup on b926 chinese version your restore chinese splash screens
