L29C432 just update by itself to NRD90M test-keys - not part of the beta program

Hello all.
My phone was on L29C432B192
Rooted, TWRP, nothing else.
I had never updated to beta of emui 5.0 because I don't have much free time those days, and I didn't feel like going into updates that would have to be re-updated in the next few months, might no be rooted yet, and might take time to sort out is everything does no go smoothly.
Sadly, my phone decided otherwise. This morning, I saw that there was an update to EMUI 5.0. I stupidly pressed "quick update" before thinking ...
Reboot on TWRP, install something, and now I'm on model L29 (no specific) build number NRD90M test-keys. (EMUI 5.0)
Some search showed me that I might no be the first : ( https://forum.xda-developers.com/mate-8/general/c432-ota-changed-build-to-nrd90m-test-t3544123 )
But this thread is a bit short, and doesn't answer all my questions. Wich specificaly are :
- Why did this happen ? Because I'm rooted and / or on TWRP ? I though B560 was a beta, and would only be pushed through OTA if you're part of the beta program. Wich I am not.
- What exactly does not work with this build ? So that I know if it's urgent that I square things up.
- What is the rollback package I must use ? Is it this one ? https://forum.xda-developers.com/mate-8/general/huawei-mate8-rollback-package-nxt-l29-t3498256
Because it says C900B500 ... wich makes me doubt that it's the right one. If not, can you direct me to the right thread for L29C432 ?
- And lastly, now that my hand has been forced into tweaking / updating the phone, what's still unstable with b560 ? Should I go back to emui 4.0 or is b560 already better ?
Thanks in advance to whoever want to takes a few minutes to help me.
I know I could find some of those infos by myself. Hell, ANY info can be found, with enough time ... but as I said, I don't have much free time. I didn't plan to get into this, and if a kind soul want to help me get in the right track, that would be mighty hepfull.

updates? same probleme here

Huawei Mate 8 Update went wrong

hi, dear xda forumers!
this is my very first post, and i am not very good at tech things, so please bear with me (plus I may unwantingly commit grammatical mistakes because i am not a native speaker and it is 2AM here)
first my back story:
I had a Huawei Mate 8 (nxt-l29c....something) European version, I had it for about 6 or 7 months, then it was stolen. By that time it had automatically upgraded to Nougat and I really liked it, got used to it, could not live without it.... so i decided to buy the same phone again. It came with Marshmallow, and I tried to update it but the OTA had been for a limited time only I guess, I emailed around with official huawei customer service asked them maybe to update my device from their headquarters or something, but they could not help me, they said I should just wait and eventually it would update.
after 3 months still nothing I grew impatient and I really wanted to have my "old experience" back, so I tried a tutorial with updating via filmware finder, using one of the first updates that were about 2GB big. It was successful, so it seemed at first, because there were no errors or interruptions, but finally when I turned it on, I noticed that during the update process my phone has lost the built in keyboard (still has the google), no more bluetooth, alarm clock, date time settings, update option
I downloaded the official rollback to Android 6 from 7 but since I updated with an unofficial update, it failed to fix my phone. now I still have the issues listed above.
Now I ended up with
Model number: NXT-L29C900B500 (originally it was NXT-L29C432B180)
EMUI version: 5.0
Android version: 7.0
Edit:
Now trying to use a new filmware from the official huawei website with the dload method
Edit 2:
it did not do anything. I will try again when I wake up
I kindly ask anyone who has any idea how to fix this to reply.

Mate 8 nougat update as far as I know have 2 update zips, I've experienced that problem when trying to update to nougat, I used twrp to flash the update.zip, I had emui 5 after but Bluetooth didn't work and some settings were missing, after searching I found that there are 2 zips to an update, a update.zip and a hwupdate.zip, basically only one was installed for you, you need to install both

Honor 8 bricked. DLOAD not working

Hi everyone,
My father had a problem with his Honor 8. When the new update was released it bricked the phone. Using the DLOAD, we were able to fix this problem, however he was still experiencing regular unwanted reboots. He decided to try changing the firmware again using the rollback file (from android 7.0 to 6.0) on a phone that was already on Android 6.0... Now the phone reboots on his own to the blue honor log screen and doesn't get out of it. We are not able to shut it off, nor go to DLOAD or anything. The only thing I was able to achieve was going to the fastboot. Anything else won't work.
The phone is an Honor 8 bought on Aliexpress. It's a AL10 version but the buyer had the FRD-L19 firmware installed on it. With the DLOAD, the last firmware the phone was on, was an EMUI 4.1 Android 6.0 L19 firmware.
Anyone has any solution in order to install newly a firmware and unbrick the phone please ?

Hi Grilla99,
Thanks for your feedback. Was it still under warranty ? Did you pay anything ?
Thanks

The instant solution. Dc-pheonix , use it , buy 15 credits worth 15 euros ,flash with firmware. Then rebrand your Honor 8 using the guide here on XDA. Njoy.

True. My solution is only if out of warranty or warranty not provided!

Hi guys !
Thanks for all you answers. The phone is still under warranty so I contacted Alianz since I had a 1 year repair warranty possibilty and I sent the phone to them. I'm now waiting for them to tell me what's going to happen with the phone.
I'll keep you updated with what's going to happen and when we'll get the phone back
Thanks again !

Hi everyone,
I got the phone back from warranty and they solved the problem. I can't really tell what they did because the paper that came with it wasn't very detailed. But the phone is working perfectly anyway.
Thanks to everyone who tried to help solving this matter

Huawei Mate 9 MHA-L09 stuck on Beta Android 8 - cannot upgrade or downgrade

I really need Help i dont know what to do...
I'll thank you already for answers.

I need to rollback (Honor 8), HELP!

I have a seemingly stupid but still annoying problem. As many of you know Android 8 + EMUI 8 came out this summer and I have updated my Honor8. Everything works well, even better (especially with regard to the battery) apart from a problem, quite annoying. I have seen that everyone around complains about the same problem, so it is clear that both a build bug and not a local problem.
Basically ... the bluetooth link with the multimedia system of my car doesn't work as it should, while it worked well with the 7.0.
Tracknames, music infos disappears, sometimes it connects regularly, starting the music, sometimes nothing happens, sometimes the music passes from the car speakers to smartphone (!!)... in short, manage the music in the car It has become a big problem!
I tried all possible options; reset pairing, reset bluetooth, clear cache, activate the developer options to control some low-level aspects of bluetooth, and finally installed Bluetooth Auto Connect which also has several advanced options. Nothing works. In the meantime an update of 8.0 has been released (mine is the buiold 521). The update came out in September ... maybe (MAYBE) this update fixes all bluetooth issues (but i don't have any detailed info about). Until today I have not received any updates and normally I check new version regularly every day. At this point I decided to return to Nougat!
And here the adventure begins!
I CANNOT IN ANY WAY do the downgrade.
What I tried:
- through HiSuite. The "back to previous version" option appears random (rarely); normally the program tells me "the system is up to date". Once appeared I tried to run the procedure, but after the decompression it gives me an error "error updating".
- by standard Rollback procedure. Using a microSD and putting the full version of Nougate in the dload folder. The installation starts but stops almost immediately with the same "update cannot be applied" error.
At this point I am desperate. I cannot update Oreo, I can't go back to Nougat and meanwhile the bluetooth still doesn't work with my car. Remember that before Oreo, everything worked very well!
What can I do? Can you help me?
Thank you

Region: EU
Model: FRD-L09
Build: 8.0.0.521 (C432)
Previous Build: don't remember. It was Nougat, and I've upgraded around the first week of September. From that day I haven't received/applied any patch, because nothing appears until now.
This morning I've tried again with HiSuite. As usual it says I'm running the latest version and it doesn't offer any downgrade option .

The more you know...

Finally I've decide to try updating to 8.0.0.562. After a month of tries, fails (damn Huawei and his stupid update system), errors and a lot of other stupid things, I was finally able to update my Honor hoping the latest version will fix all the problems. It was a enormous waste of time (searching around internet)... but in the end I found a method described here: https://forum.xda-developers.com/huawei-p20-pro/help/p20-pro-bricked-t3868085#4And if you go ahead you should find the correct firmware link (on a Russian site). Although, IMHO, failing with the classic method was due to the impossibility or some bugs in the update system, to unpack the update files on sdcard. So the solution seems to be to leave both the zip and the unpacked folder.The problems with bluetooth remain, but I hope that now there is not to be crazy applying next updates. ATTENTION: the method above is NOT valid for rollback! If you try, you'll brick your Honor.
And finally I've taken an important decision... for me this is the last Huawei/honor device. Next time I'll go to another brand, with a serious update system.
