Huawei BLA-L29 rollback to unlock bootloader - Android Q&A, Help & Troubleshooting

Hey there! First post.
Before Huawei stopped giving unlock codes in 2018 I got mine but I never unlocked because of warranty. Now I really want to unlock but from EMUI 9 onwards (I have 10.0.0.202(C432E9R1P3) installed) they removed the possibility of unlocking via the
Bash:
fastboot flashing unlock
command. I spoke today with Huawei technical support and they confirmed that, without rolling back to EMUI 8, I will not be able to unlock even with the code.
This leads us to the second issue: I cannot rollback via HiSuite, it does not show me the "other versions" button that could roll me back. Huawei support told me that button is the only official way and as it is now it is impossible for me to do a rollback due to security concerns of old EMUI versions. He also told me that the unofficial way is to install the system myself in someway he could not help me with.
I tried everything I could find online and everything I could think of but nothing worked: How do I rollback to EMUI 8 to get the unlock work?
Thanks in advance

Root/Updates/Rebranding/Unbricking - Official FunkyHuawei Support Thread for P10

This is the official FunkyHuawei support thread.
FunkyHuawei is a (mostly) paid service which allows you to do the following:
1. Install the latest system software, even before it's released by OTA.
2. Install beta/prerelease system software, without needing to be a beta tester.
3. Recover a bricked phone.
4. Rebranding / Change the region of your phone (China -> Europe, for example, to get Google and so on.)
5. Root your EMUI 8 phone, even with stock recovery (This feature is free)
Except for rooting, all of these features are supported even if you cannot unlock your phone's bootloader.
To find FunkyHuawei, please Google it. Or you can find a link to the service within the following XDA Portal article.
https://www.xda-developers.com/android-oreo-emui-6-huawei-mate-9/
We are pleased to announce FHUnbrickFlashTool -- You can now repair any recent Huawei phone via fastboot, even if you cannot access eRecovery or boot the phone! Even if it doesn't show the Huawei logo, as long as you can get a fastboot connection to your computer, you can recover the phone! Google FHUnbrickFlashTool or check FunkyHuawei's reddit for details.
In cooperation with XDA, FunkyHuawei is offering a free credit to Recognized Developers and Recognized Contributers on XDA.
Please PM me for more details.
We will continue posting in this thread with updates regarding new software versions and releases regarding this device.
We will also be monitoring it so we can help anyone who has issues.
For device-specific information, please see the next post.
P10 Device-Specific Information
The P10 now has a relatively mature community with many methods to do many things.
However, there are still some things only possible with FunkyHuawei, so it would be most useful for:
1. Installing updates on bootloader-locked devices, even if the update is not approved by Huawei for your device.
2. Rebranding bootloader-locked devices, or rebranding to obscure carrier brandings.
3. Restoring bricked devices.
Note that even though the Mate 10 Root tool is designed for the Mate 10, it works perfectly on the P10 running Android O betas.
This tool is FREE, and might be easier than installing TWRP and rooting that way.
Frequently Asked Questions
Q: How much does FunkyHuawei cost?
A: You need to buy credits on the FunkyHuawei website. The price per credit varies depending on the number of credits you buy. Different operations cost different amounts of credits. However, the Root feature of the Mate 10 tool is free, and as mentioned above, Recognized Developers/Contributors of XDA can ask for a free credit.
Q: My phone is bootloader locked, and FRP locked. My bootloader unlock code dosen't work. It won't boot. eRecovery doesn't work. Can you help?
A: Yes. With the Mate 10 this is now a common situation. Contact FunkyHuawei for help in this situation. We'll need to access your computer remotely and the procedure is a little bit complicated, but the phone can be unbricked.
Q: I can't get my bootloader unlock code/don't want to unlock my bootloader, but I want to change my phone to something other than Chinese. Can you help?
A: Yes. Our new FunkyHuawei Rebrand Tool works on ALL recent Huawei phones, to rebrand them to another region even when the bootloader is locked.
Q: I'm not seeing the latest version listed on FunkyHuawei or elsewhere as an OTA. Why not?
A: Huawei has a very odd and unpredictable way of rolling out OTA updates. You can use FunkyHuawei to install the new version immediately, or can wait for the update to be rolled out. It might be a month or more after release until the update reaches your device from Huawei directly. We have no idea why.
Q: Why isn't FunkyHuawei free?
A: Because many of FunkyHuawei's features cost FunkyHuawei money to provide. Features that don't cost FunkyHuawei money to provide, like rooting the Mate 10 or our TWRP build for Mate 9/Oreo, for example, are generally made available for free. There are also bills to pay, kids to put through school, and so on.
Q: I noticed FunkyHuawei in an XDA Portal article!
A: FunkyHuawei loves XDA, and is cooperating with them as much as possible. Recognized Developers and Contributors on the XDA forums are welcome to claim a free credit from FunkyHuawei as well.
Q: I have a different question.
A: This is what this thread is for! Post away!

Luckilly the P10 community here is mature enough that there is no longer a need for Funky's services. However effective Funky may be, we can save ourselves the 30bucks and do it ourselves

Even if it doesn't show the Huawei logo, as long as you can get a fastboot connection to your computer, you can recover the phone! Google FHUnbrickFlashTool or check FunkyHuawei's reddit for details.
We have added a brand new Android O build for the Chinese P10.
You will need to rebrand your phone to VTR-AL00 (all/cn) to install it.
Best to use HiSuite to install it -- check out Mate 10 rebranding information to find the correct version of HiSuite and instructions.
We now have Android O for International P10 and P10 Plus.
Check FunkyHuawei reddit for install instructions, or google for "Android O Builds for International P10 and P10 Plus now available! Instructions inside"
This is great news!!
If I only got some $:crying: but nice news
Does this include Treble?

Yes, of course.
Hey all, I'm having a problems to which i've been pulling my hair out and not sure what to do. Essentially, I had my phone rooted, although later decided I wanted to unroot. To unroot I used an app called "simply unroot" however it did not fully unroot my device, just made it worse, my phone does not pass the safety net, however "root checker apps" suggest my phone is not rooted, although some apps recognise my phone as being rooted. My phone bootloader is unlocked, but the OEM toggle in the developer options is not set as enabled, and is NOW greyed out so i cant click it, meaning i do not have access to any fastboot commands and thus cannot flash a recovery.img. Although, believe after having trying to unroot it had automatically disable OEM. I have tried to lock the bootloader in the hopes that OEM toggle would no longer be greyed out, but cannot do this as i dont have access to fastboot commands. Even with TWRP i cannot flash anything just promps me with Error 9. I have tried storing the UPDATE.app within the dload folder, but that doesnt work either. I have no idea how i can recover this device. Fell like i've tried everything. Please help.

Why you pose this question in the "official funkyhuawei support" thread is beyond me....
Only thing that comes to mind is: do you have USB debugging enabled in the developers options? It should be enabled if you want to use ADB or Fastboot.

I killed my Mate 10 Lite

Hello everyone. I have a very serious problem with my Mate 10 Lite (RNE-L21C432)
I tried to install oreo with Firmware Finder but I installed the wrong Firmware (for HONOR) The process was normal, but when I started the phone, HONOR appeared instead of HUAWEI and entered Recovery.
Bootloader and FRP are locked. Can anyone help? Is there a way to fix it? The huawei service told me that a motherboard should be replaced, and it costs a lot
You can try this method
BTW u need custom recovery(TWRP)
Edit:also you need to have bootloader unlocked, unfortunately if u haven't had it unlocked yet, bad news for you then because Huawei has ended their bootloader service

(Help)How to unlock bootloader in honor 10?

There is any way to unlock bootloader in honor 10 col-l29?
Nope
still not=?
still no unlock option? i've researched may there is a way via tespoints whatever it is, can somebody explain? Have a look at this:
google for Col-l29 honor 10 ( FRP testpoint Done ) Android 9.1 by MRT
sorry can't post links just yet
Not sure if someone's done it on Honor 10 but head over to the Honor Play forum, someone has put it into testpoint mode and detailed the process.
It involves taking the back off the device though.
I'm hoping the zero day exploit is possible on the Honor 10. No idea if it's even ****lt.. but.. Hold off the October update and hope!!

What are my options to Root Honor 9?

I have an STF-L09 currently on build STF-L09 8.0.0.385(C432) and security patch 1 February 2019.
It was before rooted on Android 7, the bootloader has also been unlocked using dc-unlockers.
Somehow the device got bricked. I was trying to recover it and one of my tries was to update it to Android 9, which made the phone to come back alive.
Then I tried DC unlockers to read the bootloader code again (cause silly me I didn't note it down) but, unfortunately it does not work on android 8 and above (from what I understand).
I managed to downgrade it to Android 8 using the Suite but I can't find any instructions on how to proceed from there?
My final aim is to have my device rooted on Android 9. Is that possible? I read somewhere about the testing pin etc. Im willing to do it, if the instructions are in detail.
I also wanted to add that I contacted a member of this community called "OldDroid" on the 21st October and he promised me that he can unlock the bootloader for me and it will cost me 10 Euro.
I sent him the money right away but, until today he is ignoring my messages on Telegram. He gave me a few files that did not work but that was it. After that the only responses was complains about his bad ISP so he can't upload the required files, and about his busy routine. I Asked for money back but still, message has been read but no reply.

Unlock Honor 10 possible again?

Hi guys, i received a dc-unlocker mail which says that honor 10 can be unlocked again with their tool.
Is that true?
I tried it and it still said it couldn't read the bootloader code.
Since January 21, 2021 ministryofsolutions is offering to unlock the Honor10 aswell, but It sound a bit sktechy I'm to paranoid to try it out.
Here is what he says:
Supported Models:
COL-AL00, COL-TL10, COL-L29
How it works:
We do it without opening the back cover
You must back up all important data from your phone
You need a Windows computer with a stable internet connection
30-60 minutes required
Teamviewer should be installed on your computer
We will connect remotely through Teamviewer and generate bootloader code
100% success rate (EMUI8/EMUI9/EMUI9.1)
Would be nice if anyone could say something about him or his method, since I'm a noob and won't be able to follow what he's doing to my device and tell if it's sketchy.
Why do ou want to unlock?
You know, temporary unlocking they offer will let you flash but you will never be able to boot into twrp!
You need a bootloader code and they DO NOT PROVIDE ONE!
Would be interesting if it's possible. Right now I'm considering whether to dump this thing to the trash bin or to repair it (mine has some hardware issues).
But since Honor 10 isn't listed here, I doubt it could work: https://www.dc-unlocker.com/supported_models_1/huawei_phones
