Huawei Ascend G300: no bootloader, no system.

18 posts in this topic

Posted

I visited page the page: http://huaweig300.com/
I tried to follow the instructions to make my phone capable for custom roms. Everything well until I used "BootloaderG300.exe". After I used that, my phone reboots, and reboots, and reboots...
I removed the battery and put it back and my phone continue to reboots, happens every 5 seconds.
I try to open bootloader with power+volume up and don't work. Don't work power+volume down as well. The only one who work is power+volume up+volume down and appears pink screen.
Next I try to use fastboot from my computer and put bootloader.img and clockworkmod.img when my device is in pink screen. The computer computer has recognized the driver but when I use fastboot and put .img file, say device not found, and don't work.

How I can solve my problem?

I think you need a bog standard stock GB update.app - not this downgrade package.

You then copy it to /dload/update.app on your external sdcard and do the force update.

I can't find the stock GB ROM update.app offhand but it must be here or on the Huawei site somewhere...

There are also a number of "my phone is bricked" threads in the non development forum (parent of this forum) where people successfully revived their devices - might be worth checking these out.

So you unpacked zip file and put dload folder with update.app on root of your sd card? Yes it is a GB rom. And removed battery, pressed vol + - and pwr buttons and you only get pink screen?

Found advice on xda. Guy had Ideos but its same:

 

Rittik:
Be like me. Go and tell them "Bhaisahb There was an OTA update and i was updating but the phone after turning off turned on to this pink coloured screen." They wont say a word and replace your Board. But beware u will have to wait for atleast a month for them.

Thanks. Do you think, the repair will cost? or guarantee?

Try to make it under warranty... If not, take it to specialised service and tell them exactly what you did. If you will pay for it, it will cost you less to tell them straight away than to let them do diagnostic first

Is it under warranty? Huawei repaired my rooted bricked phone under warranty without asking anything.
