Hi I am new here.
With you guides and all I have successfully rooted and unlocked the bootloader of my phone.
I saw some people had problems unlocking bootloader on 1.17 firmware, so I unlock bootloader while I was on 1.16 firmware.
After that I flashed twrp recovery and I recovery I got option to root so I even rooted my phone.
Now I want to do firmware update to 1.17.1234 and then 1.17.1531 and then android M.
Can someone tell me how to do this ?
I read that this canot be done through twrp recovery.Also I am not receiving ota due to unlocking phone.
so please provide me links to ota package to, I'm asking for ota package which is small than firmware package available on asus site.
If other ways to update tell me please

1. Download ZE550KL's Stock_boot_recovery.zip
This zip contains stock signed recovery.img and boot.img. Extract it and copy both .img files to the folder where you have adb and fastboot files.
Download correct firmware for your ZE550KL of the correct SKU. You can find your SKU on your phone's box.
WW SKU : Download ZE550KL's firmware v1.17.40.1531 for WW SKU only
Let me know if your phone's SKU is not WW
Copy the firmware zip (UL-Z00L-WW-1.17.40.1531-user.zip) to your external sd card.
2. Connect your phone to computer and Reboot phone to fastboot mode.
3. Now run the following commands
Code:
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot oem reboot-recovery
3. Third command should reboot your phone to recovery mode.
Now, in recovery mode-
A) select "wipe cache partition" then select yes
B) select "apply update from sdcard" then select "UL-Z00L-WW-1.17.40.1531-user.zip" and finally select "yes"

This is the safest way to upgrade to MM. This is exactly how I upgraded to MM yesterday. You will lose root once you flash 1.17.40.1531. But you can reroot by flashing twrp and supersu again

one we unlock the boot loader is it possible to re lock it

Help me
i followed the steps but from last 15 min it is stuck on verifying update. plz help

Reboot to fastboot mode then execute
Code:
fastboot erase system
Then flash 1.17.40.1531 zip from recovery. "Verifying update package" message will last for 2-5 mins.
Once you have flashed .1531 update you should reboot to system finish setup then flash MM ota. MM ota will be stuck at "patching system" for 15-25 mins. That is normal

Im almost on the same boat, so OP any update if you were able to fix your phone using the instructions on this thread?

how to recover?

Since I lost everything from the boot to the recovery to the system part to anything, i haven't been able to boot the phone;
I can access erecovery but when I try to recover the phone it stops at downloading and then says couldn't connect to servers so that's dead;
I can access TWRP but when I try to flash MM, it returns errors saying that it couldn't mount partitions (Vendor, cust and other...)
I can access fastboot mode. Some people suggested that I should try recovering using dload but the transfert rate to the sd card is taking forever;
Now I extracted everything from update.app using huawei firmware extractor (see http://imgur.com/MWeCCXi ) what should I flash (via fastboot) and in what order?
I would really appreciate the help.

By Nougat I assume you mean the file that has been digged out somewhere in the web and that is floating around here in the forums?
Well we all don't really know what this build exactly is, which makes it very hard to reconstruct your errors and give you advice... I would never flash that but okay, that's why we are here
Do you have a TWRP backup that you can restore (and if no, maybe somebody can upload you a clean TWRP restore file)?
Have you tried flashing CM / AICP?

Thanks for your support anyway.

Hi there. Earlier I spent a few painful hours in the same boat you were in. I've managed to get back to a fresh install of the Nougat build from this thread, but can't seem the downgrade to MM using the (translated from Spanish) instructions found here (linked from that first thread). How did you manage to get back to MM?
(I should add that I tried to flash boot, system and recovery via fastboot without any success).
Cheers

May god have mercy on your soul.
For the downgrade, I didn't use the b161 directly. I flashed some oeminfo provided in the same folder as the TWRP. Then used b150 ans the three boutons method. Worked like a charm.
Hope it will help you downgrade your phone.

I have the same problem, someone could explain it to me step by step, please

P9 Lite bricked (L31)

Hi, my problem is with the L31,
I've trying to downgrade from Nougat to MM. I saw on the thread this steps and i followed:
"Fastboot flash boot boot.img
Fastboot flash system system.img
Fastboot flash cust cust.img (This one is in the second zip from badwolf nougat download)
Then I flashed badwolfs recovery b2 as that one lets me transfer files from pc to phone and followed instructions from htcmania from here".
The problem is that i didn't reach to downgrade and when i try to reinstall Nougat by TWRP i get this error messages:
" E: Unknow comand (errno) update_huawei-pkg_from_ota_zip: update package from zip failed"
"Updater process ended with error: 7
Error installing zip file '/external_sd/DLoad/Update.zip'
Updating partition details...
...done"
Now my phone stays freeze on the huawei logo and the flashtool doesn't even recognize my device.
Can someone help me with this matter, please?

To flash img. i used the file that i attached.
Good luck

so now i restored twrp , i put the update app in sd card and it doesn't want to flash , i'm still trapped in bootloop but i have access to twrp now what to do now ?

I found the old twrp is okey for downgrade,
Just put b161 update.app into sdcard/dload and press volume down + power key.
but flash badwolf's twrp will get stuck in fastboot, though It's not really bricked.

hi, maybe you also have a solution for my problem.
i installed a wrong update via sd card (dload etc.), now my phone is just black no signal nothing. and it seems like a fastboot loop always when i plug into the pc im in fastboot without doing anything
when i try to unlock the bootloader i get "failed command not allowed")
and also when i try to flash the extracted files from update.zip i get the same error ("failed command not allowed")
by the way i didnt active usb debuggin or oem unlocking
please help thank you

I was trying to update my PRA-LA1 to Oreo. I rebranded my phone to China ROM successfully then I tried flashing the Oreo ROM and I got the above mentioned error. I can boot into fastboot but I can't boot into TWRP. If I try flashing recovery or boot it says partition length get error. Please help restore my device.

The recovery partition in Oreo is recovery_ramdisk, try flashing your TWRP (make sure it is Oreo supported) to recovery_ramdisk partition. Also your thread is in wrong forum. And before doing anything to your device, make sure you read instructions properly.

Stock ROM to UPDATE IN 2021

Hello, good day. I just wanted to ask, (Im using custom rom now and my old backup is nowhere to be found) If I am going to flash my device to official stock rom, like if I flashed the older version (lets say the MM) can I still update my device today (up to nougat) through OTA update?
i think huawei cloud is the site where we download OTA updates from but I think is already dead.
(sorry if my poiint is confusing, I just really don't know how to explain it clearly)

So if I not mistaken, your build number is VNS-L31C185 EMUI 5 (correct me if I'm wrong).
Firmware finder and Huawei old server are down, so download service ROM.
IMO now you have two possibilities:
A) flash Service ROM using dload method, guide can be found in ReleaseDoc folder. The process will erase all your data and lock the BL again!
B)
- from downloaded ROM extract BOOT.img
RECOVERY.img
SYSTEM.img
CUST.img via 'Huawei update extractor' , follow Guide
(Note: CUST.img on Nougat can be found in the second archive)
- In fastboot mode flash extracted partitions using commands
fastboot flash boot BOOT.img
fastboot flash recovery RECOVERY.img
fastboot flash system SYSTEM.img
fastboot flash cust CUST.img
- fastboot reboot
- Factory reset in stock recovery

Bro try this way out...
Download and install TWRP (if possible) and let me know
Upd.: nevermind, I forgot you don't have an sd card,.
Upd.2.: without SD you can try to flash Service ROM (or B361 firmware) using TWRP and sideload method. Unfortunately, sideload is Greek to me , so google it.

Flash TWRP over eRecovery, run command
fastboot flash recovery2 twrp.img
fastboot reboot
when a yellow warning appears on the screen, pres and hold Vol Up for 3 sec.
Edit: maybe your data partition is formatted with f2fs (after installing Elite ROM) , it should be ext4. I'm out of ideas bro, sorry.

No problem. I think I hard bricked my phone, I just got boot logo and fastboot but I can't find any fix or solution or anything to do with this.
Flashing recovery or recovery2 finished w/o any errors but I can't boot to recovery.

IMO you only need an SD card and flash the Service ROM.
