(solved) How restore /cust partition?

[asliceoflice]

Thanks

Thanks dude, helped me out a lot.

In my case, could not load twrp and should restore CUST partition
Flashing image recovery in boot partition, get booting in TWRP
With twrp or in android copy the image CUST and boot from the computer

Finally:
I flashed CUST.img in CUST partition
BOOT.img in boot partition,
and lastly, flash the zip of the rom that previously worked without problems of cust or misc partition on system

regards

I had an issue with /cust partition and managed to fix it last night.

This was a complicated process but I'll try and explain as best as I can.

You need to obtain the original stock CUST.img file. You can download the full system images from https://mega.nz/#!Kg9UiKiD!cCh9UK0Oi-P1UNk-e1RBk_jlUEHGm0MGYa_HSlQ-3c4

You also need simg2img from https://github.com/KinglyWayne/simg2img_win

copy CUST.img into the simg2img directory, edit convert.bat to change the command to: simg2img.exe CUST.img cust.ext4.img

Or open a command prompt and navigate to the folder, running simg2img.exe CUST.img cust.ext4.img

Once run you'll have an ext4 image. The original image is a sparse image - useless for direct writing.

Boot your device into TWRP. Mount internal storage then copy the new cust.ext4.img file to your device.

You need ADB on your computer for the next step. Open adb shell:

now do the following:

dd if=/sdcard/cust.ext4.img of=/dev/block/mmcblk0p23

assuming you copied the cust image to your internal storage

Once the dd process has completed, test this worked by mounting the cust partition inside TWRP. If it mounts then the dd worked correctly and your cust is restored.

Dude, if you had never posted this I would have never figured out how to fix the /cust partition. I wiped the stock MIUI rom in twrp without updating to the latest 4.0. Been stuck ever since then, including not being able to mount the /cust partition. Please keep voicing your solutions like you do!

Have a look HERE. Just type your model in the searchbox and download your firmware. Flash it through dload.

How to flash trough dload ?

How to flash trough dload ?

Place your firmware inside a folder named dload. Then power off your phone, and press the three hardware buttons simultaneously. The flashing should commence shortly.

So I create this folder in the internal memory and after I placed the file and did all things the phone flash it?
Or I can get others error and get other problems?

Yes. The flashing will most probably succeed just make sure that you download the right file for your model.
