P40 failed downgrade - Huawei P40 Questions & Answers

Ok so i downgraded my huawei p40 from emui 12 to emui 10, but the problem is that i downgraded to emui 10.1.0.182, and, well i lost usb connection and fast charging, i tried updating via ota, but it says im up to date, i used erecovery, but it gives me the error retrieving package info, i tried dload with otg, but when i go to update in recovery it stays there for a while and then gives me the error ´´this update does not exist´´, so i dont know what else to do.
Edit: I used a transcend card instead of the one i was using and it now worked, i believe SanDisk cards also work; then i eventually got the OTAs, also when u get an OTA, you need to restart the phone in order to get the next one.

Stuck with bootloader/eRecovery

Some context:
My MHA-L29C432B138 with TWRP got an OTA update on the phone itself, and I wanted to update (it wanted me to update to B182).
Since I had TWRP replacing the stock recovery I could not flash it through the normal way, so I went ahead to replace TWRP with the stock recovery so I could update.
I was unable to flash the stock recovery since I had no access to flashing in fastboot (FRP Lock, PHONE Unlocked, OEM unlocking option greyed out in developer settings), so I attempted to relock so I could unlock again, hoping that would solve my issue (fastboot oem relock KEY).
By doing this my phone went into a reset, now I'm stuck at FRP Lock, PHONE Relocked, and I can only access the bootloader and eRecovery.
eRecovery is attempting to download updates but fails every time, and I can't use HiSuite to do a system recovery neither (says my device is not supported).
So this is where I'm stuck, any help would be nice!

Try to unlock after this.
This does low-level format.
My device: Mate 9 supersu B190 Mediapad X2 GEM 701->703 B212 KangVIP (AJ mod)
Everything in fastboot (flashing, locking, unlocking) was unavailable, eRecovery was not working, HiSuite said my device was not supported, and dload didn't work neither (tried 3 different firmware versions).
After spending 1-2 hours on Telegram with others I ended up using funkyhuawei with eRecovery, only thing that worked for me.
Last time I buy a Huawei device for sure, their own services don't even work (eRecovery, HiSuite).

As I said here, for your case the patched HiSuite method would have worked. But it's too late now, you paid, I was in holidays.. I know it's a shame that HiSuite says unsupported or erecovery not working but you could have made your phone compatible by writing some text in a file and using Lucx's script instead of paying funkyhuawei, their service never worked for me.

Softbrick after using official updater (C636), had to downgrade. Better rebrand?

Hey guys,
I had my Honor 8 in L19C636B380 update for a long time now.
Yesterday I tried to update with official app, I selected an option "full update", or something like that, since the app said there was no update available.
However, with that option in the menu, It found the B390 update and began the update, but the phone bricked in eRecovery mode.
I've tried the 390 update through dload method without luck. Tried full-MV of 380 without luck (recovery will stop at 5% and won't install the firmwares).
Now I'm trying the 360 full-MV-PV update (a downgrade), which seems to go past the 5% in recovery... It worked.
Considering that the european version is way ahead of the asian pacific, I'd like to know if you guys can point me to a way to rebrand to the european version, since this C636 version is stuck in 2017 (or at least my phone won't pick any OTA updated here in Brazil). I've seem some directions in the forum, but some have broken links and stuff, so I fear I may get stuck in the middle of a process...

Huawei Mate 8 - Cannot force update "software install failed"

Hi All,
I am struggling to force update my Huawai mate 8.
Current running on version NXT-DL00 8.0.0.839(C17)
I am unable to use WIFI update as my WIFI has not worked for a long time to perform hard reset/recovery.
I do not have USB Debugging enabled and at present I am unable to enable this as my digitizer also does not want to work.
The EMUI gets to around 5% and then I receive the error
Software Install Failed
and refers me to the below link which is of no use.
https://consumer.huawei.com/cn/emui/?mod=restore
I have tried a number of firmware downloads and nothing gets any further.
The reason I am trying to update is to hopefully get my digitizer working again, I have already fitted a new one and this did not fix it so I do not believe it is a hardware issue.
Any suggestions at all would be appreciated.
This is a really good phone and I do not want to just chuck it in the bin, I have purchased a Mate 20 Lite as the replacement but would prefer to get my old one working again and use it as I miss it
Many thanks in advance for your support.

Having trouble upgrading your phone?

I almost resorted to unlocking the bootloader of my Huawei Mate 9
So my friend and I swapped phone. I gave him my Huawei P9 and he gave me his Mate 9. The unit's stuck on EMUI 5 / Android 7. I know that later updates have been around for quite some time now. First, I tried searching for updates through the system updater-- didn't work. I flashed firmware through "dload method" which also failed miserably. Then I read that you can "force" an update thru TWRP. As a preparation, I downloaded HiSuite to backup some data on my PC. I sh*t you not, the app immediately detected an update. The app allowed me to update the phone (a series of updates though) to the latest version. So if you're facing the same predicament, try this out.
Download HiSuite for PC, install, connect your Huawei phone, and the application will then guide you on how to set things up. On successful connection, an option (HiSuite on PC) may detect an update for your phone. The app will download the update and install it on your phone. You may choose not to update too.
Tried same. Nadda. Still stuck on Android 7 and Emu 5

Honor 8 frd-l02 test keys

Hello,
Please, i need help. I have problem with my honor 8.
Ill start from begining.
My original fw was frd-l02c432. (Im from eu, czech rep.) But since i wanted oreo update, ive done something wrong. Ive downloaded new update, and ended up with nrd90 test keys. After little play, ive manage to downgrade to frd-l02 c675. Just was unable to upgrade. ive download new sw via FF, install, and now im stuck again on test keys. I cant install twrp. Because, when i unlock bootloader, the oem option will grey out, and cant switch on. Cant install FF, because i have no keyboard. (Also update option is missing in settings) Erecovery is not working - cant find package. And when i download recovery package for c675b130 (or c432) and update via dload, it stuck in 5%- failed.
Is there some way to resurect him back to land of living ? or his only way to live is service center. I know, its almost sure, but i want to try fix it myself. And leave the service as a last resort.
Emui 5.0
Android 7.0
Thanks and have a nice rest of the weekend.
Andy.
EDIT: ok ive solved it (i think ) ive flashed twrp to boot instead of recovery. So phone did not start, but i was able to enter twrp. Then rebranded phone to frd L09 (my region with 432) via TWRP. Instal B380 via FF (with unlocked bootloader and twrp). then reflash TWRP back to normal recovery (because when the phone showed me new update, I was unable to install. ive downloaded the update, then hit install. Phone restarted to twrp and it showed me "error 7" when installing. So Ive uninstaled twrp. then download again. Phone restarted and update installed just fine). i just need to download the "latest package" via update from system everytime, so it will take time Maybe it will help someone. see ya
