Fixed my bricked P9 on B166 how do i update to the latest Nougat build??

I previously attempted to get on to the latest Nougat FW which ended up in a soft brick which required DC-Phoenix to fix after flashing a b136 recovery rom back to the phone. I have unlocked bootload, but dont think i have root or TWRP installed anymore, im guessing after a complete recovery stock rom flash that gets removed, is there a way to check?.
What is the safest method for me to get to MM B166 FW to the latest Nougat FW please?
EDIT: am now on B182 updated via HiSuite

Can not upgrade to B390 (C432)

Hi,
I'm on C432, unlock bootloader. (It's a debranded phone).
I can't update. to B390.
I did a clean install of B386 using TWRP (flash the 2 zip file, clean cache). B386 works fine.
Update from phone did upload the B390 update, it rebooted into Huawei recovery and it failed at 12%. "Software installed failed".
So I've tried with TWRP (I have downloaded the B390 from Firmware finder) and it fails on update.zip with an error 7.
I've tried various versions of B390 (from Firmware finder) and they all fail when trying to install update.zip from TWRP.
Flashing back B386 with TWRP works (no errors when flashing update.zip).
It seems the update.zip from B390 tries to look for something missing in my phone....
Any ideas ?
Thanks !

Stay on B386 unless you're really keen for the latest security update.
Peace.
I can' t even go back to B182, B383. Only B386 I can install (hopefully). This tells me that something is corrupted in my phone.
I have the following error with TWRP:
assert_failed: block_image_verify("/dev/block/platform/hi_mci.0/by-name/system", "package_extract_file("system.transfer.list"), "system.new.dat", "system.patch.dat")
ERROR 7
With other update.zip, I also have
assert(update_huawei_pkg_from_ota_zip("UPDATE.APP"));
What's wrong in my phone ?

albelushi7 the problem is that update.zip fails with TWRP because of the assert.
I guess the problem is because my VENDOR, PRODUCT, VERSION are probably corrupted (or may be other partitions).
I can't flash them using fastboot.
I looking for a TWRP backup of these partitions for a L09C432 model. Can someone share a backup of these partitions ?
(Even a full backup with B390 installed for a L09C432 would be great !)
Thanks !
I'm going crazy with this. Tried to rollback to MM everything time I try to flash, it fails.
Either by
- TWRP : Update.zip fails with ERROR 7
- Huawei updater + HiSuite
- 3 Button methold and dload folder.
I can only flash B386. It works fairly OK but with some random crashes.
I don't understand what's wrong with my phone. It was an Orange phone, debranded to C432. I had several updates without any issues and problem came since B383.
Could not update with Phone updater to B386. Did with TWRP. But now, I can't install anything. Only B386 can be installed !!!

same thing happen with my phone. now, i use c185 with b390. you should try the same.
So you flashed the OemCust for C185 and it worked ? Good to know !
You were on C432 before ?
Did you try revert back to your original OemCust ?
Thanks !
Hi! I had the same problem. I solved it in this way:
Backup app+data with titanium
Revert to MM with the official procedure, upgrade via updater to nougat and install, always via updater the updtes until B390. Works everything.
The I reunlocked bootlader via adb, install twrp, rooted and restore apps with titanium.
Long procedure, but it worked

How lucky ! I did install MM Rollback and then MM (C432B136). I was on stock recovery and bootloader locked.
Update B136 -> B160 : Ok
Update B160 -> B182 : Failed
Now I can barely install anything (B386 anymore, it used, now it doesn't). Only TWRP...

When I downgraded to MM I was already on b182. I immediately had the nougat update available.

You'd have to flash back stock recovery, then install OTA.
When it has finished you'd have to flash TWRP and Magisk again.
OR you could see if that particular update is available on http://pro-teammt.ru/firmware-database/
If so you can install it using TWRP with HuRUpdater. But you'd have to use TWRP by pretoriano80 as official TWRP is pretty bareboned...

You would still have to flash Magisk after, but saves you the trip to fastboot
