Blue screen , no recovery, no fast boot and update 2/2 failed

[Guest fayis003]

I have huawei ascend y300-0000, After creating some wrong partition by ram expander my phone got bricked and giviing only blue screen on startup. Now only way to do is update.app update but i dont have any idea what was the exact rom with which the phone packed... i tried some roms including b209 but no luck.. its about 2years since i am using this phone and have used lots of custom roms too. But now i cant do anything if i could go to recovery by any means, i could flash custom roms or restore from backup but no luck. If you guys have any clues to fix this issue or any one had and fixed this please share the fix or idea.

 

thanks for all

Did you create swap in mmcblk0p2 or p3? Have you tried booting to fastboot mode?

[Guest fayis003]

sorry i have no idea on which dir its created .... but am pretty sure its created swap on wrong place because these issue happened after i hv played with ramexpander ... :( and i can go to the pink screen and update from update.app but no official firmware seems gonna flash successfully as giving update failed on 2/2 step.. 

is there any way to know the exact official firmware which match to ma phone model ?

[Guest wbrambley]

No way to tell your original firmware that I know. The b209 update was for y300-100 not the -000.

[Guest fayis003]

any firmware which mach to all u8833 devices ?

[Guest fayis003]

i tried imei hack but disappointed as the terminal cant recognize the device.. one time dc-unlocker could recognize ma phone but dc-unlocker doesnt have any option to reset phone :(

[Guest wbrambley]

So you have fastboot, that's a good start. Now maybe try to fastboot flash the damaged partitions, probably p3 or p2.

[Guest fayis003]

dc unlocker only recognized device once. now its not, :( i think i messed with the drivers.. could u please guide me how to flash the damaged partitions... if the device wd be recognized by the twrp adb terminal once i cd install twrp and install custom roms but it just showing "waiting for device" :(

[Guest wbrambley]

Disconnect phone from pc, hold power and volume down for 10 seconds. Reconnect to pc. open cmd/shell and type "fastboot devices"

Edit: this assumes fastboot is in your system path, if it doesn't work navigate to folder with adb/fastboot.
