[Request] EMMC backup of G6-U10 (tutorials included)

[bugggmenot]

Hi, my G6-U10 is hard bricked and has gone to QDLoader 9008 mode so i cant go to recovery, fastboot,adb mode .
i need EMMC image of a similare device (G6-U10) so i can fix it following instructions in this thread .
i dont need whole EMMC image, just first 100-200 MB .
to extract EMMC, you need to be on stock rom with root access.
to do so:
1. Enable "USB debugging" in "Developer Options". then connect your device to Windows PC.
2. download and extract ADB. then run the following command through CMD:

adb shell
su
dd if=/dev/block/mmcblk0 of=/sdcard/EMMC.img bs=100m count=1

note that you must enter each row separately and confirm the dialogs appeared on your device screen to grant root and adb access for pc. the option bs=100m mean that the dd command will only extract first 100MB of EMMC. and FYI, this file is only backup from system partition, not from any private files, no need to worry.
the extracted file will be in internal SD, named EMMC.img , compress it in ZIP or RAR so it will have much less size, then send it here to solve many people's problems. anybody does that, i'll appreciate.
Thanks for reading.

Thanks bro, but it's just 100bytes, not 100Mbytes. i think you used bs=100 instead of bs=100m
please consider reuploading , you are my saviour

info on the progress:
I got EMMC image thanks to @washichi :good: (download it from attachments).
then i could finally wake my device up, in the fastboot and recovery, following instructions in this thread(first post).

i can go into Fastboot mode but though i had unlocked bootloader (before), but i can only flash recovery, system(partly) and boot partitions. other partitions give me error ((Remote: Not Allowed)).
the only recovery that i could go into, was the latest TWRP 3 . in recovery i can even connect my device in MTP mode to pc and see files on the internal SD! but i was not successful with flashing roms, it always gives me error mounting cache, system, data. ADB mode is also accessible, used adb sideload to flash rom, but it didnt worked too!
i think part of internal SD is damaged and need to be fixed somehow. still havent found out how.

so, for guys who are having problems similar to me or "Internal Storage Damaged blah blah" i recommend trying to follow these steps to see if their internal SD is still flashable or not:
1. Download an official Rom for your device and unpack it using HuaweiUpdateExtractor.
2. download and extract latest (at least 1.0.32) fastboot in the same folder as extracted huawei IMG files are (Gush bless me! there's too much grammatical erros in my texts )
3. connect your device in fastboot mode (instructions above).
4. go to the directory where all extracted files place. Hold shift and right click on empty space, chose "Open command window here".
Note: you must have an unlocked bootloader to be able to continue, type this command to see if its unlocked:

fastboot oem get-bootinfo

if you're unlocked, then continue reading, if not, i dont think there is a way to find unlock key for your device.even DC unlocker cant recognize your device in fastboot and adb.
5. now that you know you have an unlocked BL, type these commands one bye one:

fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash aboot aboot.img
fastboot flash tz tz.img
fastboot flash userdata userdata.img
fastboot flash [COLOR="RoyalBlue"]XXX [/COLOR][COLOR="SeaGreen"]XXX[/COLOR].img

as i said before, i could only flash 3 partitions with success. but if you where able to flash all parts with success, your extremely have a chance to revive your device. at last, type fastboot reboot to see if you boot up successfully, if not, you will go again in fastboot mode or recovery mode.
for me, default recovery mode just freezes, so i flashed TWRP 3 instead of default recovery. you can try that too.
one more thing: you might not be successful to reboot into recovery, you must restart until you succeed. if you stuck in freezed recovery, open the device back, unscrew the little steel plate (it has 2 screws) and dettach the battery cord, wait 3 secs, re-attach it. i have done it more than 300 times now i dont even know where is the steel plate

FYI, EMMC image in the attachment is for G6-U10 only and probably will not work for other G6 models. if you want G6-L11 emmc, i can share it for you.

if anything was not clear for you, ask me.

@bugggmenot Everytime i insert the sd card and try to enter fastboot mode by holding the Volume+, the PC keeps beeping and refreshing the device manager, tho i can't see any hardware detected. The phone isn't recognizable as fastboot device and the LED is lighting in a blue color.
Any ideas?

Do as follows:
1. detach the battery and retach it again.
2. connect the device to pc WITHOUT holding any buttons.
3. if you go into fastboot mode, you will see a blue "Fastboot mode" in middle of texts (and Blue LED).
4. type in cmd: fastboot devices
if your device is listed, you are good to go for flashing procedure.

oh and one more important thing: install fastboot and adb drivers. it's a global driver not device specific, so install any you van find ( sorry I can't Google it for you right now).

Did everything still doesn't want to boot in fastboot mode.
Edit: I made it to the fastboot, thank you very much.

Happy to hear that. would be great if you share your way of success and your current progress on reviving the device. it might help many people.

I got it to the progress you did. Was able to flash only boot.img recovery.img and like 950MB of system.img. Yet smth makes me to think that everything i do flash is being flashed in the SDcard memory not in the internal one, is it supposed to be like that?
Edit1: Tried to flash an update.zip which i made by using huawei tools extractor from the stock recovery but the verification aborted the update. Tried with CWM by using adb sideload but there was some error while sending, also tried with TWRP which seems to erase its memory everytime when i restart the phone, the adb sideload doesnt work and couldn't found the flashable zip after i pushed it in by using adb

i dont think so.
i thought like you, but to test it i went to TWRP recovery and removed SD card, Formated SD (via MiniTool Partition) and reinserted SD into device. at this level , device cant recognize SD anymore, so i reformatted SD via TWRP (i dont remember the exact path, sorry), and this time SD appeared in PC ! so i simply put flashable SlimStock and flashed it via TWRP. but it exactly took the time that it had taken before when i tried to flash SlimStock via Sideload. and in both ways, it takes about 30 min to pass the system.img flashing ! so this can be a proof that in the both ways, images are being flashed on the internal SD, not ExSD.
any way, at this point it seems that we cannot go any further. but who knows? we made a dead device into TWRP, so why not...

Well i did try flashing img files via TWRP but it allows me to modify just recovery or boot partition. Tried also making flashable zip of the partition to run it from CWM but i get stuck.
I also tried

fastboot flashing unlock_critical

and

flashing unlock

but i recieve 3 dots, maybe i should be more patient next time to see what will happen.
===========================================================================
@bugggmenot i've found the file for G6-C00 for qualcomm bootloader platform. Will they work on G6-U10???

Why not try to repartition your device?
You can you the parted binary (google will find it) and put it on your /sdcard or / (the root folder). NOT your internald memory or any other partition thats your EMMC.
Now umount ALL partitions in recovery, except for the external sdcard. Go to the commandline in the recovery and cd to the parted binary. Now typ 'parted /dev/block/mmcblk0'.
Type 'print' to see your partition table.
You can now modify your partition table (only ext2 and fat32 partitions support, BUT you can format it whit your recovery soo it will be ext4. (Dont check RM format in settings!).

Hope this will fix the flashing problem.

Hard Brick

Hello guys, i don't know if this is the right place, but do you know how to unbrick Huawei Y550 - L03 from hard brick? My pc recognizes it in the device manager just as Android adapter PCUI (COM10) but the device itself doesn't show.

Thank you in advance if you can help me please. :crying:

Here i put EMMC for G6-L11 for people who need it:

 

[rakovm]

Hello, can you explain how you made it from dead phone QDLoader 9008 to recovery?

 

[henrucci]

Here i put EMMC for G6-L11 for people who need it:

We should use the Yureka tutorial with this file to bring the G6-L11 to life right?

only if your phone is G6-L11, then the answer is yes.
