Can anyone help?
I'm trying to use TWRP to install FRD-L14C567B385 onto a rom which just read as "test keys".
I get the following error.

Its little bit funny how many people have problem with rollback packages. Where you think is problem, in rollback packages or in low information about procedures, maybe low experience of each user...?

Its easy bro . Everyone gets this issue just beacuse of the lack of proper investigation.
It is even easy to revert to previous version when u do a good research in xda .

I had to use DC-Phoenix, which unlocked BL and flashed update.app. I couldn't do it manually, because my phone wasn't detected by adb devices and I didn't know that code you need for unlocking bl manually, dload method didn't want to turn on.

Flash stock recovery and then do the rollback, you should be fine. Then you can install TWRP and mess up your phone again

Hi all
first of all, i am a noob as I have not been using android for years.
This is the stupid thing I have done so far. let me start the story on how I get this phone.
1. I bought it for 2nd hand, and noticed it has installed with the 'fake' nougat rom http://forum.xda-developers.com/p8max/general/android-nougat-p8max-t3492952
2. I check the phone it's shows not rooted.
3. It come with TWRP.
4. the Model is DAV-701LV100R001C209D305 ( do I need to download the exact same rom? I can't find it anywhere)
5. I wiped out everything including internal memory. and the phone now looping at the 'Huawei logo'
5. So I wanted to restore back to the original rom and downloaded some rom from Huawei website for 701L, when I press the +,- and power button it shows fail, some incapability things....
what shall I do now? I really lost now. please help!!!.. I just need a working phone:crying::crying::crying:
The problem is that there a no full ROM for this device so you cant forceupdate it.

I think the only thing maybe could work is that you put a universal CUST on it and flash a "normal" ROM on it than.

I think I need original factory image

Factory Image won't work unfortunately...I purchased a stock image of my Phone. But made the mistake of using one of the DGTKS files that was closest to my L09 model as instructed in the unbrick method (METHOD 2) I succeeded in unbricking my phone and then flashing my Factory Image but lost my imei & serial...so I used HCU to reinstate my imei etc and managed to get a very week signal that would cut out as soon as you went inside or jumped in the car.
Nothing I tried worked ( flashed modem img etc) I had the phone back to out of the box state ( Bootloader locked ...stated in Fastboot ) but weak signal. I took it back to the manufacturer who didn't seem to detect that I had mucked around with the firmware and replaced the motherboard under warranty.
I was given a second chance and dodged an expensive bullet.....I havn't even unlocked the bootloader on the replacement phone.
XDA site needs to warn people to stay away from this method (method 2) If I ever was stupid enough to brick my phone again, I would use the Phoenix tool only to flash my own firmware and never their modified DGTKS files which I can concur that the NXT files for the mate 8 have all been removed from their supported firmware list.
As i tel to other people , you need to erase modemnvm_factory / modemnvm_system / modemnvm_backup partions and to flash them with a partions comming from a full working mate 8
Tested and worked my mate 8 work correctly now
But sorry for all who wait for solution i can't share this files it's the choice of the person who helped me to do this and they have right
I will do my possible to try to help you all as soon as possible

For the moment i used dc-pheonix and xml scrypt that i have edited from an original factory rom unpacked not like the one in dc unocker
Edited it to erase and write the new partions only
But the right partions have to be dumped from a fully working mate 8 and than flashed to your bricked one
I will try to create a free solution soon to do not have to pay again dc unlocker

If something is different in the C567 boot image you'd need someone with a C567 to extract their boot. I'll see if I can find any but I guess you have tried already.

Agreed... I will not mess up with the device if it already rooted... Given that we do not have the unbrick tool.. I am wondering why we would need to go back to stock with locked bootloader? When returning the device to nubia for support? Ignore it as they will be able to identify if the device was unlocked or rooted... So waste of efforts..
