How to unbrick? Bootloader seems to be locked

[Guest Dssj]

Hi, I`ve got a bricked Ascend G300. When I turn it on, it shows Huawei logo for 10 seconds and then turns off. Same with entering recovery. The only working modes are fastboot and the pink update mode. But the bootloader seems ro be locked:

C:\Users\Honza\Android>fastboot oem get-bootinfo
                              ... INFO
*******************************************
INFO    Bootloader Lock State: LOCKED

INFO    System State: OK
INFO    Bootloader Version: 001.001.000
INFO
*******************************************
OKAY [  0.006s]
finished. total time: 0.006s

But it could not be unlocked:

C:\Users\Honza\Android>fastboot oem unlock #####################
                              ... FAILED (remote: Unlock failed)
finished. total time: 87.389s

The pink update mode doesn`t work too. I tried cca 10 ICS firmwares and everything fails after decompressing (in step2/2)

 

How can I unlock the bootloader? Or how to erase IMEI to update via pink mode? Or is here any other method to unbrick?

I read somewhere that when my PC recognizes the phone (by typing fastboot devices) it can be unbricked. Is it true?

Thanks

You could try downloading a ROM zip file (Any ROM) and then typing

fastboot update rom.zip

where rom.zip is the Zip File with the ROM in it, which is in the same directory as the fastboot directory

I tried it, but it says something like that some files (i don't rememner the name, but in .txt) are missing

Try b926. It is known to bring phones back from dead

Doesn`t help  :(

C:\Users\Honza\Android>fastboot update
archive does not contain 'android-info.txt'
archive does not contain 'android-product.txt'
error: update package has no android-info.txt or android-product.txt

The pink update error is always the same. Failed at the beggining of step 2

 

By the way, is there any other command than "fastboot oem get-bootinfo" which tells me something about the phone?

I searched for them, tried many commands like

fastboot oem list_partition_emmc
fastboot oem check_emmc
fastboot oem check_emmc_mid

but nothing works on g300

You have to specify a ROM zip! :wacko:

so for example if I wanted to flash:

G300_ROM.zip

I would type:

fastboot update G300_ROM.zip

I would then type

fastboot reboot

to reboot the phone.

 

 

 

Remember that

G300_ROM.zip

has to be in the same folder as

fastboot.exe

for my commands to work...

Yes, that i tried too with the same error. "fastboot update" flashes automaticaly an update.zip in the folder with fastboot

DSSJ - take it to warranty, there is no way to unlock some kinds of G300 without starting it.

 

Yeah, tested middle package, tested "pink mode" to update via update.app (B952), older GB one, but again without zeroing cant do any of FORCED UPDATE.

 

The thing with fastboot and ANY ROM is stupidity. When you have locked BL, you cannot run custom ROMs even repack of stock ROM.

I got my G300 bricked due the locked BL and installed repack. (repack installed on unlocked BL, but restored 5irom bck of IMEI - the first Ive made - after boot brick)

In service they cant fix it with software but with changing HW part (some module or so)... 

 

No one understand because they have different brand of G300. I understand cause with DSSJ have the same one... (no forced update)

Mhmm, I left the phone a couple of days in the desk (without battery, because it's broken and the health one I have in the second phone) and now it seems to be completly dead. Doesn't respond to anything. When i left it with battery pulled in overnight, it just discharged it. So i thing it's broken motherboard. Thanks for help...

Or dead Hynix eMMC?

[Guest Dssj]

Don't know. When i got it, it was already bricked.
