(Q) "Huawei cust fail" error and the solution?

My device's rom is MT7-L09V100R001C00B133SP11, I tried to install B127 MT7-L09 West Europe rom but have error while installing the rom. The error is "huawei cust fail". I tried many roms (B120, B121, B126, B127) but no success and everytime the same error. But I can flash only its original rom MT7-L09V100R001C00B133SP11 without any problem. How to solve this problem? Help please.

No problem flashing cust. When I put the rom dload and to install full rom it gives error. I could not flash any rom from dload except b133.

Then extract the desired Rome and boot.img, recovery.img, system.img and cust.img manual flash.
command:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash cust cust.img
Then it should start and you can do that Rome again completely FLASHE.

I did everything you write. Everytime no success. I think there was a regional lock on our phones. I think I must flash more img files to unlock regional lock.

Of course, the boot loader mechanism to be open. More imgs can not flash itself. All other get error messages.
Open bootloader, flash Custom Rom would be an alternative.

My bootloader is unlocked. Which custom rom can I flash.

Try it so that is close to stock and deodexd.

But it says "In addition, you should the B127 MT7-L09 Western Europe or the B122SP06 installed, otherwise it will get to the bootloop." and my rom is not b127 or b126. My rom is b133. Will it bootloop.

b127 is the minimum requirement, you lie already higher. If so beware.

I'm in cust fail error drama like you, i have TL 10 international stuck in b119 original firmware but i got root with alternative method whitout unlock boot loader.
Cust fail appears even if i simply Hard reset my phone the root remains
No ROM upgrade via ota non ROM can be flashed via SD card method.
My questions:
Can i try to flash original firmware via fast boot without unlock boot loader first?
I unpacked update.app with extractor and got many file : cust boot recovery modem etc
Which One should i flash and in which order?
Thnks in advance forma help

Without unlocked bootloader you can not flash imgs. If you have unpack the zip you a dload folder that is on the SD and you can flash.

Hey guys, so if I want to flash stock recovery, do I need to unlock bootloader? Which I did...
Then when I tried flashing the extracted recovery.img, the error message was
"target reported maximum downloaded size of 471859200 bytes
error: CAN'T LOAD RECOVERY.IMAGE: no error"
So would you guys tell me what happened?
Thanks!

BTW, do I need to root the phone before I can flash the stock recovery? Could someone point me to the right direction? Thanks!

Hey. Just boot your phone into fastboot mode. flash the blu_spark recovery.IMG.
Now the phone reboots into twrp blu_spark recovery. Now you can transfer the zip to your phone storage (mount option in twrp) or use usb otg .
And now you can flash the zip and you are good to go

Not sure what you have done to get to this point. I would start over with the MSN tool or you could try fastboot rom.

I have pretty much the same issue:
- "standard" TWRP wouln't boot (stuck at crashdump)
- blu spark TWRP boots and installs but afterwards phone doesn't boot anymore ("boots" into crashdump)
I have solved the phone-not-booting part by reflashing everything (meaning that I am now on a phone that is just stock with unlocked bootloader).
The MSM Download Tool could be the solution to our issue but I'm now off to work.

erecovery honor 6x android o no flash

hi
i'm want to flash stock recovery and erecovery
but erecovery whit commond fastboot flash recovery_ramdisk_b no flash
Flash correctly
But again, twrp will boot
twrp in the erecovery
sorry for my english

That's because your command is wrong. The command is same as the one you used for flashing TWRP. i.e fastboot flash recovery_ramdisk nameofrecovery.img

Why so you need those recoveries again?

Correct Command
If you want to flash the "E"Recovery, your command has to be "fastboot flash erecovery_ramdisk nameofyourimg.img"

I used this command but did not work

I'v flashed TWRP on my 6x. But IMHO Nougat and Oreo have different boot methods:
Nougat:
Power on > Unlocked screen warning > now press and keep pressed Vol.+ = TWRP (if flashed as eRecovery)
Oreo:
Power on > Unlocked screen warning > now press and keep pressed Vol.+ = stock eRecovery
Power and Vol. + keep pressed at the same time= TWRP
Please try and let me know if is your same condition!

I have tried everything ( both stable & Beta). I flash several twrp. But after flash 1st time stuck on twrp logo(nothing else). When i tried to enter recovery again that time stuck on mi logo.

you can try : copy the recovery.img (or name of your twrp.img) in your sdcard, flash twrp with fastboot command, boot in twrp with fastboot command, choose install image and flash again recovery.img, in twrp choose reboot recovery, format data-system-cache-dalvik, and flash a custom rom...

I've tried with mi flash. Its shows successfully flash. But i cant boot in miui recovery.

have you tried to boot in twrp by fastboot command from a computer ?( not with power and vol+)
for flash you use : fastboot flash recovery xxxx.img
for boot : fastboot boot xxxx.img
