Lock bootloader again with oeminfo to try the warranty repair - Huawei P10 Questions & Answers

Hi, unfortunately my p10 drop on the floor from an high of 8 cm... Yes almost 4 in an the camera now has a strange yellow border. Of course this issue happens only on the color camera. The b/w camera works well.
The problem is that I have unlocked the bootloader. Can I do something to prepare the phone for rma?
I've the original oem info and of course the unlock code.
Thank you in advance

Maybe downgrade to nougat and then ota update to oreo will help. When I made debrand had unlocked bootloader and frp. Then did ota update to oreo and now have bootloader and frp properly locked.

What guide should I follow for this?

For debrand I used this guide:
https://forum.xda-developers.com/p10/how-to/huawei-p10-debrand-rebrand-update-guide-t3691013
but I was doing it on nougat and I am not sure how it works with downgrading from oreo to nougat.
If you are already on oreo (and C432 region) you could try to use this guide :
https://forum.xda-developers.com/p10/how-to/guide-manual-updgrade-to-update-oreo-t3758286
tutorial 2 to flash the first full-ota oreo 8.0.0.360 from: http://pro-teammt.ru/firmware-database
but here is question to @Jannomag if it's certain that the script will work from newer to older oreo version. If so then try to use HiSuite to downgrade to nougat (for .360 it should be possible when hit firmware update -> switch to other version) and finally do the ota update to oreo. Be aware that I am not absolutely sure it will work, just suppose it should.

Downgrading to a lower version as Dec2018 security patches can be indeed a problem but this shouldn't cause a brick. The updated should fail flashing /kernel and /ramdisk from update files.

I tried to flash B365 oreo over B384 with tutorial 2, update started as usual then reached 100% and phone switched off totaly. Now looks like bricked, can't switch on, charging doesn't work, when connected to pc system shows unrecognized USB SER device. Is there any hope to unbrick it?

I have the same. Send to warranty and they fix this by replace the Motherboard. Now i can't unlock bootloader because no offical codes and DC unlocker not support newest security patch from Huawei. Otherwise Phone works fine and i have extra warranty to 2022 .

Version downgrade

I have searched everywhere but I didn't find a reply to my question.
A couple of days ago I have updated my phone LLD-L31 to the version 8.0.0.132 through Firmware Finder (it worked for me with proxy method) then I decided to revert back to the previous version 8.0.0.131. So I started reading guides to install a firmware on Huawei/Honor devices, I have downloaded the FullOTA package version 8.0.0.131 with Firmware Finder, placed it in the folder dload on my SDcard and started the intstallation in the project menu (accessible digiting *#*#2846579#*#* in the dialer), it started but suddenly it ended with a message "installation failed".
So my question is: how can i revert to the previous version of the software (or to the out of the box firmware installed on my device)?

You should have an option to downgrade in the about section/ the update menu of your phone if you did it right.
Otherwise you may need to use the HuRupdater Method.

Thanks for your reply!
I don't have this option, but if I remember well I hadn't it also in the previous version of the firmware.
So i can't install a previous version of the firmware simply downloading it an putting into dload folder of the SDcard?

Can you please specify why do you want to roll back?
Because most people just wanna upgrade to a newer version.Newwr versions will have better stability so it's recommended to keep the latest version unless you have some bugs.
I honestly don't know why the dload method doesn't work, seems that it doesn't work for most people.
I think you'll be able to roll back using HuRupdater. But that'll mean you'll have to unlock bootloader and flash twrp first. Then you can go all stock from there.
Here's a guide to the HuRupdater from @zxz0O0

After installing the version 132 I asked the technical support through HiCare and they told me that installing firmware with Firmware Finder could void warranty so I decided to revert to the previous firmware and wait for regular OTA by Huawei.

I'm not sure but I think you are on the latest build for your varient now so you won't be getting any updates untill a next build comes in.
I don't think you'll be able to roll back without the firmwares from firmware finder as you don't have an option to roll back.
The best option now would be to just wait for the next official build(might come soon as a small ota which has security patches) and then check if you are facing any issues installing which you won't as you are not rooted and dosent have an unlocked bootloader. So don't worry ?

Want to downgrade my honor 9 lite
After some update the theme engine crashed. Themes can no longer change the notiifcation bar icons and shortcuts icons.
Downgrading version Problem
I used firmware finder and dns method to downgrade my honor 9 lite and while i register update on firware finder and opens hisuite for update it is saying u r on already the latest version
Plz help me with downgrading my version 9 to 8

Can't update my P9

My P9 is currently running Nougat and I want to update to Oreo but in "About phone" it says I'm running Android 5.1 and EMUI 3.1 (I'm 99% sure I'm running Nougat). My phone is second hand and I've never rooted it but the last owner might've (if so then it got unrooted before it was sold). I have 4 months left on my warranty if it matters. Whenever I put update.app into a dload folder on my SD card I get an error at 5% when trying to update saying "Software install failed, Incompatibility with current version. Please download the correct update package." I use Firmware Finder to find the latest update and in "About phone" it says my build number is "EMUI-A168-L09C432B040SP11-log" so that's what version of updates I download. I don't get any OTA updates and Firmware Finder's DNC and proxy method don't work for me either. When downloading Nougat I did it manually (through dload) and I think it was some sort of beta or leaked version or something. I don't know what else to try but I just want Oreo on my phone. My bootloader isn't unlocked and my phone is definitely not rooted. I live in the UK so my phone is most likely from there too. What should I do or try?
Edit: I just tried updating my phone through Firmware Finder using the proxy but I get a package checksum error when I try
"Android 5.1 ... 99% Nougat" - Can you post the screenshot of your Settings/About (mask your IMEI) to see what are really your EMUI and Android versions. Also, scrolling down in About should show date (month, year) of the Google security patch - usually it means that Huawei built the ROM the same or next month.
You can also install from Google Play apps like My Device or DevCheck to see if they recognize it as Nougat
Googling for emui-a168-l09c432b040sp11-log finds that it was some early beta version (June 2016) for Android N, see eg (Chrome can automatically translate from Hungarian to English)
https://huaweiblog.hu/tag/emui-a168-l09c432b040sp11-log/
Frankly, I don't believe the phone under warranty was released with beta Nougat, rather that previous owner installed the beta (also I don't know is the phone covered by warranty with that beta N).
Look also to XDA, thread
https://forum.xda-developers.com/showpost.php?p=67931734&postcount=62
subsequent posts, how people who installed beta N (c432 cust or other custs like c900) went back to their official Marshmallow (or upgraded to official Nougat).
"tried updating my phone through Firmware Finder" - I don't find anything at all on Firmware Finder for EMUI-A168.
IMO, you cannot 'update' from your EMUI-A168-L09C432 to the regular EVA-L09C432 (good that it didn't brick your phone). Generally, going from one model/cust to another requires rebranding which is a whole different process, not just taking whatever ZIPs from Finder Finder and flashing them by DLOAD or by DNS/proxy in FF.
IMO, you must go back from your Beta N to official MM (from that time). Then (if it was EVA-L09C432) you will receive OTA updates to official N, or if necessary you will need to rebrand to eg c432 (since some other custs, like English Vodafone, got stuck at MM, there are no N builds for them).
Of course, rebranding (it voids the warranty), if necessary, requires to unlock the Bootloader.
Finally, Oreo is available only for Chinese cust, not even for European c432, and it requires (unlocking Bootloader and) HWOTA7 method, but for that you must first get rid of your Beta N (even rebrand if necessary - see above) to be able to start the HWOTA7 process towards the Chinese Oreo from some of the latest official Nougat builds, see
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
I'm not sure if HWOTA7 (that can be also used for updating Nougat builds ans rebranding from one Nougat cust to another) is applicable to your Beta N.

It's probably not even neccessary, it is already c432, it should be enough to flash c432 b182 by DLOADvto come back to c432 MM, and then OTA updates will bring him to the latest c432 b50x Nougat - no unlocking bootliader needed
To the other side HWOTA7 might be risky as it requires EMUI 5 and it's not sure is it there in that early Nougat beta build

HWOTA7 directly from that b040sp11 might be risky as HWOTA7 requires pure EMUI 5 and it's not sure is it there in that early Nougat beta build - therefore going back to MM c432 b182 is betrer (google, you will find people from that time doing so from that Nougat beta)
Once at b182, OTA will bring him to the latest c432 Nougat (his warranty will be back) and then if he wants he can unlock bootliader and use HWOTA7 to go to Oreo (without warranty anymore)
Here you find EVA-L09c432b182 and how to flash it
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
Only the following steps apply for you:
2, 11, 12, 13, 14, 15
With the small modification for step (11):
- ignore the first sentence "Go back to main menu and reboot your phone - but not to system. " since you are not coming here from TWRP
- instead, switch the phone off and then boot as in the second sentence "You must press Vol+ and Vol- (in the middle) down until EMUI Software Installing begin and b182 will flashed" and continue with the rest
Upon the OTAs as in step (15), you will have official c432 Nougat (and your warranty)
Later, it's up to you if you want to unlock Bootloader (4 Euros needed for the Bootloader code) and to upgrade to Oreo by use of HWOTA7 method

What is not understood, there is no Oreo and there won't be for European, Mid East, etc custs
There is (official, no beta) but only for Chinese cust.

Update EVA-L09C900B182

I have a Huawei P9 that doesn't seem to receive updates.
EMUI 4.1.1
Build: EVA-L09C900B182
Andriod: 6.0
I have tried using firmware finder but I always get checksum failed before it passes 1%.
I had a look through the Forums and it seems that people recommend rebranding though that was in 2017.
I was wondering if there is any easy way to update?
I am a noob so i want to try avoid rooting and rebranding if possible.
Has anyone managed to update this?
2 years later and I'm still trying...

For c900 there is no newer firmware.
Flashing anything else than c900 means rebranding - but rebranding requires unlocking Bootloader (not 'rooting')
So wandering, what are you really trying to do for two years?!
- Unlock Bootloader (4 Euros):
https://www.dc-unlocker.com/
- Rebrand properly to be able to update to Nougat eg EVA-L09c432b504:
https://forum.xda-developers.com/showpost.php?p=72153575&postcount=2
I followed that guide but now my phone is stuck on "Type the password to decrypt storage" when I enter my Google password it says it's correct but data on my phone is corrupted. Any ideas?

Are you talking about TWRP asking for pass or Android?
If Android, on which firmware are you, what was the last step you performed?
Also, make sure you used TWRP for MM, not for Nougat - since you were on c900 MM when you started with rebranding to c432 (?)
Btw, you unlocked the Bootloader?
Thanks for the quick response and all your assistance. I managed to finally boot into EVA-L09C432B182 and will write what I did in the rebranding post for others who run into this issue. I still have no updates on L09C432B182 though.

For OTA you must have a valid SIM card and WiFi - check manually to the System Update to trigger checking for an update
You can also try with HiSuite (PC) - latest versions of HiSuite have an option at the bottom to update the firmware
See:
https://huaweiflash.com/how-to-flash-huawei-stock-firmware-all-methods/
You can also update by DLOAD (read the guide above), you must download FullOTA-MF-PV (must be PV), like b360, from Firmware Finder
There is also HWOTA method, see:
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3

You can't. Since bootloader was updated on Oreo you can only go back to the oldest build with new bootloader.
You can install board firmware, but you would have to update to the build that introduced new bootloader, else it bricks again.
I also doubt Huawei would allow some way to downgrade that far, as it would be a "security" risk. (for them, as you could acquire bootloader unlock code that way. You still can on board firmware but that requires testpoint which voids warranty)
@ante0 I have bricked vtr-l29 probably because of the 02 switch in xloader you've mentioned. Do you think it would be possible to unbrick with testpoint and board firmware with modified xloader taken from after gpu patch firmware?
