If you get your phone fixed,please tell me.chaosn wroteMy G4 just died, it got stuck in bootloop, I was able to backup my data using the Freezing technic.
The phone was bought from ksa i need to check if it still under warranty to get it fix or else in the bin.
I don't know how easy to get a new motherboard to replace and what would guarrantee the replaced ship won't get stuck in bootloop.
If you know how much will cost a new G4 motherboard, please post the price and how you got it.
It's not known what motherboards will bootloop and what won't,so your best bet is to sell it after your fix it(if still under warranty!!).
