Hi guys,
I am trying to flash the OEM info as its currently on according to DC unlocker:
Found Phone : VNS-L11
Model : Huawei HiSilicon Kirin Android phone
IMEI : 860921031654789
Firmware : VNS-C900B161
SIM Lock status : unlocked
my phone about device screen displays:
Model: HUAWEI VNS-L31
BUILD : VNS-L31C432B161
EMUI 4.1.1
ANDROID 6.0
I have downgraded to MM B161 thinking this will help and has factory reset my phone during the process but no luck.
I get a boot-loader unlocked warning since i was on nougat, and unable to lock or unlock the boot-loader when i try.
when trying to flash TWRP recovery i get: FAILED (remote: image verification error)
OEM UNLOCK is enabled and so is DEBUGGING
any ideas, really be great to get this fixed finally
Try to download again TWRP the use the command:
fastboot flash recovery twrp.img

Bypass bootloader unlock data wipe

Is there any script to bypass factory reset after unlock bootloader in emui 8?
Or I don't know if there is some apl like odin inorder to flash files with locked boooadee for huawei devices?
And as second question can u use my previous bootloader code (emui 5) to unlock emui 8 bootloader?
Use dload method to flash service ROM. I think there is service ROM for EMUI 8 now as well, at least for the European version of the phone I think, not really sure. The bootloader resets to state "locked". If you relock using "relock" in fastboot, it will show "relocked". And yes, you can use the same code to unlock again, it changes only if the motherboard in the phone gets changed.
I know about dload method and used for upgrade to emui 8
Im going to unlock my bootloader and flash twrp
Im looking for a trick like some OPO script that can bypass data wipe after unlocking.

Re-lock Bootloader

How to relock the bootloader after the oreo update ??
i tried skipping the gpt and the bootloader but the boot img is giving the downgrade error.:crying:
Without the Oreo firmware, it won't be possible to relock. You need your GPT, bootloader, boot (kernel), system, OEM and other partitions to be on the same firmware level, else the partition checksums won't match and at best your device won't lock, and at worst you'll boot loop/brick your device.
You'd also need firmware as new or newer than your bootloader to relock, which means the Oreo firmware. I would not advise trying to downgrade your device to lock your bootloader.

How do I unlock the bootloader on EMUI 9

Hi, I wish to run Open Kirin for EMUI 9 but I'm not sure how to unlock my bootloader on EMUI 9, if it's possible how would I do it?
Thanks
You need the bootloader code.
You use the command by ADB fastboot oem unlock as you normally do.
If you don't have the bootloader code, it downgrade to an older version of EMUI 8, get the bootloader code with Dc-unlocker and let the device update to EMUI 9, open the bootloader and install the rom.

Impossible to unlock bootloader and root Zenfone 3 Max Zc520tl X008D Oreo

Hi please help me I'm desperate.
This is my horrible phone
Zenfone 3 Zc520tl X008D with Oreo 8.1
I would like to root it with magisk but I have a lot of problems.
FIRST. I have to unlock the bootloader but Asus didn't release the tool for Oreo.
I tried to unlock through fastboot using these following commands
fastboot flashing unlock
fastboot oem unlock
But nothing happens. How can I unlock the bootloader?
SECOND. I didn't find, in the case I will be able to unlock the bootloader, TWRP recovery or better I found TWRP in a guide about rooting this model but with Nougat OS. The question is. Can I use this TWRP for Nougat or I need a TWRP designed for the model with Oreo?
An alternative, I found here a guide to root this device without TWRP patching boot.img with Magisk Manager and flashing it through fastboot. Could it be a valid solution?
But please help me to unlock this bootloader. I will never buy again asus ZenFone. They disappeared a d if I ask for the unlock tool Oreo they answer: we will refer this to our technicians

Click to expand...
Click to collapse
The Oreo update came in 2018 and i doubt they release anything 2 years later. And i think that tool is required to even be able to use those commands in fastboot. So if you want to unlock bootloader you should downgrade to an older version and use the tool , which i am currently looking for.
