Hi

download stock ROM for your region and flash it with stock recovery

it should fix your problem

I've already tried. Unfortunately, breaking the update process with an error message.

Have anyone an Idea?

You need to restore a stock recovery first.

Have anyone an Idea?

first off what model is your phone ?
do you still have TWRP installed ?
how are you trying to apply the update ? from phone off or from update.app

Flash this with TWRP >> http://loadbalancing.modaco.com/download.php?file=customromtemplate-5x-plk21-b130-r3.zip

Thank you for the link. The installation is, however, again with the error "fail to mount / cust invalid commando"

what version of TWRP are you using ? Use this one
did you reboot recovery and try again ?
did you try to go to TWRP / Mount and choose /cust and try again ?

if all these fail your going to need to take it to a service center theirs nothing else to do

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.

a question:
cust.img is 205.403 KB (kiw-21L-B130)
the conversion in cust.ext4.img arrive at 524.288 KB
mmcblk0p23 (cust partition) in the device is just 507.904 KB
is normal?

 

[bly2]

It worked! Thank you thanks for your guidance and effortless !

Yeah, no problem. Sizes will look different on the device but the image fits.

http://www.hihonor.com/nl/support/details/?DOC_ID=84203 KIW L21 West EU try this i had same issue and it solved it. Click on downloaden (Sorry its Dutch) unzip it put the update.app file in the root of your SDcard in a folder named 'dload'. This should solve the System Failed Error that u normally get with this methode WEST EU ONLY
