Huawei Ascend XT2 (H1711)?

[crashburn833]

For XT2 with unlocked BL, unrooted, stock recovery:

Do NOT try
fastboot format userdata

It will brick the device


Solution: boot to Stock Recovery -> do a Factory reset

fails at 5%

 

[yuweng]

i don't know why it fail as f2fs is enabled, the default XT2 kernel source does have f2fs enabled too but the stock kernel doesn't boot so there is no way to confirmed whether it is the kernel or TWRP problem.

CONFIG_F2FS_FS_ENCRYPTION=y
CONFIG_F2FS_FS=y
CONFIG_F2FS_STAT_FS=y
CONFIG_F2FS_FS_XATTR=y
CONFIG_F2FS_FS_POSIX_ACL=y
CONFIG_F2FS_FS_SECURITY=y

And i have completely forgotten that TWRP does have logs so i need you to repeat your whole process then attach the logs here. There are two ways, At TWRP => Advanced => Copy Log to SDCard or adb pull /tmp/recovery.log

Hopefully that will give some clues to unbrick your XT2 :fingers-crossed:

Sorry, the partition size is too big for a single image.
SparseConverter XDA page

Use this userdata.img.bz2 as it's much smaller.

For simplicity, let's flash this from twrp / Advanced / Terminal:

dd if=/external_sd/userdata.img.bz2 | bzip2 -dc | dd of=/dev/block/bootdevice/by-name/userdata

Let me know if that works. If not, I'll try to split up the image into pieces.

now /data cannot be mounted

Note: I just performed the below on my device, and it successfully returns the device (/data) to factory. It will take a while (5-10min) to boot, then start up with the Google setup screen.

now i just need /system and it will boot i think (i have multiple issues due to my own stupidity)

 

[aslezak]

Here is my system.img

Need to do the same you did with userdata (dd | bzip2 | dd) to restore from TWRP / Advanced / Terminal

now i just need /system and it will boot i think (i have multiple issues due to my own stupidity)

 

[crashburn833]

Also got new TWRP and setting up a new thread. Cause this one is a train wreck. And I can update it more efficiently. As things get improved and added

You can only mount the ext4 partitions and neglect f2fs, my twrp was fully functional this way.

Anyone know how to be able to write to the system so things like BusyBox and Xposed can install and work?

[SuperBrolySSJ]

Is there something I did wrong? Here's what I did:

1. Flash TWRP (the first one that was posted)
2. Backed up system and boot to my SD card just in case
3. Flashed the Super SU zip, then rebooted and then downloaded Phh's superuser


I know I'm rooted, but I cannot install BusyBox or Xposed no matter how many times I try.

Odd... Get termux and see if you can su

I can


When I try to install BusyBox, it says that it's installed, but if I reboot and go back to BusyBox it says not installed, and Xposed still won't install

 

[faxanidu]

Try this one.
