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
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

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.

flash this file with twrp and install stock recovery and do reset factor / finally use hisuite to rollback
So like a dummy I flashed the wrong firmware on my P40 Pro. LGRP6 instead of LGRP4. Now when booting it says "Your device has loaded a different operating system" and then goes straight to erecovery. In eRecovery, downloading and restoring the system doesn't work because it fails to retrieve package info.
I already tried everything possible with HiSuite Proxy, too. I read bricking a P40 Pro this way requires to replace the motherboard, but not sure how true that is. My phone is still under warranty, but I'd prefer to fix it myself, if possible.
Any ideas? Thanks.
Tried eRecovery without any sim card in it?

Yes, I just get retrieving package info failed. Every time
Then it seems motherboard replacement is the only known option left.
Same issue with me
I spent a month to fix it and didn't find a way.
I tried Chimera Mobile and it didn't helped.
The only thing that probably can help is SigmaKey software. If anybody has it please check and say did it helped or not.
Huawei don't want to replace it by warranty for me, that is why I try everything.

I can't find anybody with SigmaKey. Probably I'll go to replace the motherboard in the nearest future.
Other methods definetely don't help.
Do you have any update? Please share if yes.
Hi all! My device is finally fixed! It was fixed by disassembly, hardware testpoint and flashing of Android 11 via SigmaKey!
You have to find a very expirienced person to do this work. I can recommend one person in Moscow, Russia in private messages.
Disassembly is probably necessary

Thanks for the update!
After 4 days trying everythingI found also a guy who told me exactly what you are saying. disassembly is required because of the test point. No other way currently.
SoI will go to a phone shop tomorrow to disassemble the back cover of my P40Pro+. Then the guy will do the whole flashing process via remote. But it's paid service for 30$. I decided to do or because I wanna use this phone.

The only other way is to try to replace the motherboard by warranty.
However, in my case Huawei refused me this.
I think 30$ is a good price because it was very difficult for me to find a person good enough to do it.
Hi guys. Just posting a small update here. I found a xda user who accepted to help me unbrick my P40 Pro for a donation via remote desktop. He will be using paid tools and hopefully it will unbrick the device. I'll post another update soon, to let you guys know the outcome. Fingers crossed!

It is not always possible without disassembly. (Like was in my case)
I wish you good luck but be ready for disassembly.
Another update. First of all big thanks to @oslo83 for accepting to help me with my bricked P40 Pro. Unfortunately things didn't go our way and the device is still bricked. The problem is that I flashed LGRP6 EMUI 11, with EMUI 10.1 preload & cust. A ****ty situation but it is what it is. @oslo83 advised me to take the device to Huawei repair center (it's still under warranty) and that's what I'm going to do.
However if anyone has a bricked P40 Pro, I still recommend oslo83 services, there's a chance your brick is different from mine and that he will be able to unbrick it. If not, he will issue a refund like he did for me.
Hi guys, I have a brilliant update for you guys:
The guy I was working on this issue was able to fix my phone remotely with SigmaKey. After hours of tries he made it!
There is no software solution yet - so the back cover has to be dissembled. I went to a phone shop at the corner and let them open it. After removing ca. 10 screws you can reach the "Test Point". There are some videos on YouTube which can support you. Its not easy but its makable.
The genius guy gives a step by step instruction what to do via WhatsApp.
So at the end my P40Pro+ works again and I am so happy! I will start the downgrade now (to install gms)and I will DEFINITELY use the correct FW this time
I can share the contact - send me a private message.
Another update hopefully the next one will be the FINAL one.
So like @oslo83 suggested, I contacted Huawei via chat on their official site. They accepted to repair my device for free with no problem. I sent my phone to the repair center and now I simply have to wait. The person in the Huawei chat told me it could take up to two weeks. And another thing, they let me know the phone will be updated to the latest firmware, so I probably won't be able to downgrade and install GMS, unless there is a way to install it on EMUI 11 (not sure). But at least I'll have a working P40 Pro again
I have the same problem. I'm tryingto fix it with hsuite proxy and the phone in fastboot&rescue mod
In HiSuiteConfig.xml I added to be able to enter the recovery mode
<rule type="ELS-N29" cnName="HUAWEI P40 Pro" enName="HUAWEI P40 Pro" option="" ></rule>
I'm testing to flash this:
Base version: ELS-LGRP4-OVS 10.1.0.176
Custom version: ELS-N29-CUST 10.1.0.8(C432)
Preload version: ELS-N29-PRELOAD 10.1.0.2(C432R5)
Checked "Recovery OS", CUST PKG and Preloaded PKG
So far it connects
I can download and unpack the firmware on the phone
but then I have an error-message on (Installing 0%) telling me, that on this phone the recovery mode is not available. I'm trying with different base firmware - but every attempt takes a lot of time.

Still trying to reflash ... any ideas?
I've built now my own dload
using the files downloaded by hsuite over hisuite proxy inside Hisuite\ROM/
and copy them on a USB-C-drive /dload
trying the usb-flashing method. So far it went only to 37%
Hi,
I was able to finally get google on my phone about a year ago. I was able to update my phone once, manually, by downloading the firmware manually from the FF-app/website and connecting it to HiSuite.
For 8 months now, I havent been able to do this process anymore because FF-app/website shows me no working firmware. I think my phone is in risk because some of my passwords have been hacked and im almost sure its not my laptop. I am ready, if i have to, to do a factory reset. I was told when adding google services, that even after a reset, the google services will remain on my phone.. But then the issue is still not solved as my phone doesnt want to update by itself. It always says the firmware is the latest one which is impossible after 8 months or longer not updating it.
When using FF app, every single firmware i click, it tells me: Error, most likely the firmware was removed from the server.
When i try to download a firmware from the desktop it says: An error occured.
I feel like im stuck.. What should i do?
My huawei P40 PRO+
Model: ELS LGRP6 or ELS N39 (im not sure which one it is. the 2nd one is written on my phone but the first one is written on a paper from 1 year ago)
Build number: 10.1.0.175(C432E2R3P3)
Emui version: 10.1.0
Thank you a lot for anyone reading this and being able to help me!
You must use this site for firmware search. https://www.firmfinder.ml/
You receive updates, or not?
The issue is solved thanks to one of a senior member. Thank you so so much!
You are welcome!
The solution was that:
- downgrade using dload firmware
- install Google with googlefier
- OTA update to the last EMUI version ( he requested that)
Android 11 update is downloading and installing as I write this. US model. North American Retail channel.
Just sharing.

I'm not sure if it's 11 or 12 (I know 12 does for sure) that breaks AA on phone, but I'm not taking any chances - one of them or both do. This Ace is the only phone I have left with 10.
I'm having a problem with this ota update of my unrooted phone to android 11. It seems stuck at step 3 of 6.
I've seen the update process go as far as 66% of step 3 of 6 several times only for it to restart step 3 again and again. Something does not allow it to complete installing step 3. Internet has been available throughout.
Any suggestions? Is there another way to update?
Researching the web for why the android 11 is not installing on my phone I discovered all the bugs that the moto android 11 update apparently introduces. So I guess I'm lucky the update did not take. I turned off smart updates and will wait to see if and when Moto will get its act together.

It will probably show by now (3 days later). I had the same thing after an unintentional upgrade to 11, but that cleared after only a day when I connected to the Internet again. But apparently the typical wait time is 3 days. (EDIT/ADD) If it still isn't showing, try a reboot.
FYI (all), this phone CAN be downgraded back to Android 10 -- with an UNLOCKED bootloader only. I posted my experience in this Q&A section -- by accident (oops!) so it might get moved at any time to Guides, News and Discussion. Thus I won't post a link here because it might change. If you decide you want to downgrade just look for "Downgrading Motorola One 5G Ace".
I guess I was lucky the ota 'upgrade' to 11 got stuck on step 3.
Android 10 works fine for me except for random reboots. If I find a solution for that all would be well.
