Unlock BL, root and Roms or Downgrade - Huawei P10 Plus ROMs, Kernels, Recoveries, & Other

Can anyone explain how to unlock the bootloader and rooting works under Emotion UI 9.1.
Since the Huawei has blocked the bootloader codes and no longer releases them to users, the P10 plus has not been developed.
If I have a boot loader code, how do I go about unlocking the boot loader, how do I root my device and is there any way to downgrade?
Because there is the possibility for me to get a boot loader code for my P10 plus, so I would like to ask in advance how the procedure is.
It could be that I probably have to downgrade my device to the older e-motion Ui version so that I can even root and import custom ROMs. Is that right.
Thank you i hope the Comunity can help me.
My Device is
VKYL09C432 Emui 9.1 Last Patch from July19

[HELP] Will I ever be able to unlock bootloader again?

Hi all. So I recently bricked my device while trying to update to oreo.
What I did was rebrand my device from PRA-LA1 to PRA-AL00X(P8 Lite 2017 to Honor 8 Lite) which was required for updating to Oreo. After that, I typed in the command from TWRP to install the update.zip, but nothing happened so I rebooted my device. It boots up as Honor and my eRecovery and fastboot still works, but my bootloader locked when I rebranded.
As I'm typing this, I managed to connect to WiFi and its downloading the firmware, but what I was wondering is will it be possible again to unlock bootloader again? Because my IMEI number obviously changed since rebranding and I didn't save the unlock code so I was wondering if I manage to unbrick this device if it'll be possible to unlock bootloader again with the new IMEI. Any help will be appreciated.

Bootloader Unlock -> Questions , Firmware : VTR-L09 8.0.0.382

Hello All.
I am relativly new to the XDA forum. Mostly i read stuff here, to get very good infos about problems you can run into, and i was able to solve them by reading some threads here. So really glad something like this exit ! Now i think i need to be a lil bit more active inside XDA to get more precise answers. I am a bit confused about the topic: "Bootloader Unlock". So i don´t know which solution might be the best to acomplish my task : get "bootloader unlock" / "root" & "TWRP" on my Huawei P10.
This is my Model :
HUAWEI P10 : VTR-L09
Firmware : VTR-L09 8.0.0.382
Since the official-Huawei sites which provided the "Bootloader Unlock" has been closed, i only found these non-Huawei sites, which promise to provide the "Bootloader Unlock":
1.) Ministry of Solutions ( hxxps_//ministryofsolutions.com/huawei-bootloader-unlock-paid-service-htm )
2.) Global Unlocking Solutions ( hxxps_//global-unlocking-solutions.miiduu.com/bootloader-unlock-codes-choose-model-below )
3.) Funky Huawei ( hxxps_//funkyhuawei.club/buycodes )
4.) Huawei Sim Unlock ( hxxps_//xxx.huaweisimunlock.com/huawei-unlock-prices.html#prices )
5.) DC - Unlocker ( hxxps_//xxx.dc-unlocker.com/ )
6.) HCU - Client ( hxxps_//hcu-client.com/features/ )
(can´t provide Links, because new user)
I guess these "pay"-method services are the only way to get your codes for the "Bootloader Unlock" !? Can anyone confirm, that these listed-services, or some of them works ? (Sadly DC-Unlocker didn´t worked for me. Maybe i´ve done something wrong)
a.) Is it correct, that you need to rollDown from Oreo to Nougat to unlock your bootloader ? (i got Oreo on my phone)
b.) You can´t even think of to "root" your phone and get "TWRP" on it, before you don´t unlocked the Bootloader ? (Or are there maybe other methods to get "root" & "TWRP" onto P10)
It would be great, if someone can give some hints, expirences, or Links to another threads which handles this topic. When on both questions a.) & b.) the answer is = true, so my biggest problem than is, to get my phone unlocked (Bootloader unlock) !
Thanks in advance

No! You still can unlock your bootloader with Oreo installed. You just need the unlock code.

Yes, you need TWRP to root your phone, because you need to flash either SuperSU or Magisk. With stock recovery it's not possible, but you can flash stock recovery after you rooted, if you wish.
This are the direct anwers to your questions, now I'll go a bit further:
Unlock:
DC Phoenix is the only tool which I confirm it's working to unlock the phone.
You're right, Huawei stopped to provide the unlock code to "provide the best expierence for all users". I call this bull****, since DC Phoenix and FunkyHuawei are driven by Huawei.
But if you want to unlock, the only way is to pay - and DC Phoenix works (don't ask me how, I never used it, I just read many posts about it) - it's also cheap with $4.
NOTICE: AN UNLOCK WILL CAUSE A FACTORY RESET!
TWRP:
I can recommend the TWRP by @espaciosalter20 even it's just for testing purpose.
For me it works very well. This version also supports /data decryption (it's the only version for P10 atm, I believe).
Root:
The best way to root is with Magisk, because it's a safe method and the tweaks as systemless installed. This is good for passing SafetyNet, even if it doesn't work for every app (SafetyNet is a check if your phone is unlocked and rooted, some apps check it, mostly banking apps, but also games like Mario Run).
For this, you need to unlock and install TWRP. After this you can proceed installing Magisk.
- Just download the latest stable zip, the manager apk and also the uninstaller, if something went wrong.
- Make a backup of /system if it makes problems while or after installing.
- Install the Magisk zip via TWRP
- Boot the phone (takes a bit!)
- Install the Manager app.
- Done.
If you want to unroot you can either flash your /system backup or update your phone to the same or a newer version with my guide.
I hope this answered all questions!
Have fun with your P10 - and backup your unlock code if you got one!
Thx for the detailed answer !
I´ve done allready rooting with my current Honor 6 (yeah, its also a huawei brand). And it worked smoothly. Because i don´t needed huawei or any service to get a "Bootloader Unlock"-Code.
I got my unlock Code by an App !!! Don´t believe it ? Its called "HonorTuner" ( hxxps_//forum.xda-developers.com/mate-7/general/unlock-code-via-honortuner-t3217651 ). Really a great App. But it seems it only works for older Honor-Devices. I wish something like that app would exist for Huawei P10. Anyways, just wanted to say, that doing the rooting on "P10" is pain in the ass (without a bootloader unlock code).
As said before, i didn´t managed to get a unlock code or to unlock the bootloader with the tool DC-Unlocker. Do you know whats the difference between DC-Unlocker & DC-Phoenix ? I think i need a step-by-step Tutorial to get it working with DC-Phoenix / DE-Unlocker. The last time, i tried it with DC-Unlocker it went wrong, and i lost money . Therefore i just want to be prepared, with a tutorial on it.
@absynteZero created a guide, maybe this helps.
Thx very much @Jannomag. I think this is exactly what i was searching for. I will try it out, as soon as i get some more time. Afterwards i will give you here some feedback about my P10 Bootloader unlock / rooting / -story
I am back. (or better to say my phone)
Now with a little help of this forum, i succeeded to "unlock the Bootloader". Thx to the provided links of "Jannomag". My TWRP version was from this links and the guide-how-to. It was very well explained.
So i can confirm that DC-Unlocker (DC-unlocker client software V1.00.1403) works with an Huawei P10 Oreo OS. I just paid 4,-eur to get 4-credits and with it you can read out the Bootloader Code. It is important
that your ADB Drivers recognize your phone. You can check it by typing into the CMD "adb devices", it should display you your phone serial number. Best way to install all nescecary drivers is to install the actual HiSuite, because everything goes automaticly. Next step is to Start DC-Unlocker, connect your phone to PC, find your phone inside DC-Unlocker (there must be shown a COM-x port with a number). After this step you need to log-in within DC-Unlocker Server (after you paid 4,-eur , you got a user name + password). Finaly you can click on "unlocking" and "read Bootloader Code". In few seconds you got your Code. You should copy n pasta this Code somewhere onto your SD-Card / PC.
After my Bootloader was unlocked, i was able to install TWRP and with TWRP i was able to install Magisk v18.0 , the newest version. I was also able to update my OREO ver. VTR-L09 8.0.0.382(C02)-FULL to VTR-L09 8.0.0.389(C02)-FULL with TWRP oreoupdate , Tutorial-2 ( https://forum.xda-developers.com/p10/how-to/guide-manual-updgrade-to-update-oreo-t3758286 ). Mission accomplished

Can you please confirm it worked even it says in the warning:
WARNING:
Huawei P10 VTR-xxx upgraded to Android 8x not supported
Huawei P10 plus VKY-xxx upgraded to Android 8x not supported
I am asking as I tried to unlock bootloader thru https://ministryofsolutions.com but got refunded as "Huawei has updated security and its impossible to read bootloader unlock code on new firmwares. Only 30 euro service can unlock latest firmware bootloader. "
Thanks!
Trust me ... as long as you have an Oreo OS, you are able to read the Bootloader Code. Its seems its not a big deal for DC-Unlocker. And in comparison to 30,-eur ... 4,-eur seems much cheaper . I really don´t like these methods and i am angry Huawei closed their possibility to get a Code from them, i was forced to use such a service. However, the first time i tried DC-Unlocker it didn´t worked because i was unknown about the procedure. I lost 15,-eur. And gladly i found help on this forum here. With some detailed guides / tutorials it worked for me on a second try. Give it a try. You really need to follow the instructions in the guides. Thats it.

Hi,
Have you used DC-Unlocker tool or DC-Phoenix? (Not shure about differences)
Here is what Dc-unlocker support told to me: (My info: P10 Vtr-L09. 8.0.0.381 (C432).)
"We do not have bootloader unlock service at all. Chances to read bootloader unlock code from your mobile version on our tool is very low as well."
So I'm noy sure to try...

It is really sad that there is no central point for finding the information about unlocking the boatloader for P10 phones.
I used LOS, CM, AOSP, CAF and cousins for more than 5 years on at least 6-7 devices and now feel completely helpless to be able to use OpenKirin. On XDA P10/P10+ forums lots of posts are outdated as they are pre Oreo updates and on OpenKirin chat it is a no-no question.
Just not sure how the development is supposed to stay alive longer for these beautiful phones...

You should be able to use DCUnlocker, but you may need to downgrade first (my guess is to a firmware version before July 2018). Downgrading can be done with the dload method, but it works only with specific firmware versions, check: https://forum.xda-developers.com/showpost.php?p=78558134&postcount=41
A new unlock method is also available via the Big Huawei Exploits telegram group. This is free but a bit complicated.

Look for @huaweihax on Telegram.
Guys,
You don´t need a downgrade, at all !!!
You just need to download DC-Unlocker. Read the Links of the guides in the first posts. Thats it . Don´t waste time downgrading VTR-L09 to Nougat. Just start unlock with OREO. And whats the Problem here ? 4,- eurs ?? C´mon. Buying a "Kebap" for 4,-eurs or geting Bootloader-Codes for 4,-eurs. Think about. I also mentioned whats really important & all posts before explained everything. Nothing more to say. I also had an email conversation with the support team from DC-Unlocker. They told me the same....but i think the guy for the support don´t know everything (because he is not the dev, of course). So in the end its your descition. I can confirm that i read out Bootloader Code on 2x Huawei P10 : C02 & C432 Phones with both Oreo OS on it with DC-Unlocker !!! ... Nevertheless i wish you success & braveness.
(Please...nobody can destroy his phone. Why this panic ? It is a "read out" not "writing". Just reading out a Code for a Bootloader. You can get panic when you are "writing" f.e. new recovery.img / new OS, and so on. This can destroy your phone if you do something wrong. I allready get into Bootloop, no boot into OS etc. Than i got into panic. But this is a different story)
Hi there, i can confirm similar to sledgehammer, the DC Unlocker worked for my P10plus already with OREO, i was able to read the bootloader code. The latest DC Unlocker version shows detailed the procedure to correctly read this code. You simply have to follow these instructions. the 4 EUR was it worth.
@Sledgeham @dc_01 What was the security patch of the oreo versions you unlocked with DCUnlocker? Were they before July 2018?
No patches, just used software that was on the phone (i bought 2nd hand). These 2x Huawei p10 phones were "vanilla". No Bootloader unlock, no ROOT etc. Just as it is. First phone was: VTR-L09 8.0.0.382 (C02) and i MANUALLY UPDATED this to VTR-L09 8.0.0.389 (C02) (after Bootloader unlock, with TWRP). Second phone was: VTR-L09 8.0.0.376 (C432) and i MANUALLY UPDATED this to VTR-L09 8.0.0.379 (C432) (after Bootloader unlock, with TWRP).
I think security patch was written something with 01.01.2019 and the other was something dec. 2018. But i didn´t pay much attention onto this dates. I think the exact dates you can get from the ROM vers. which was provided on a specific date, if its important for you. In my opinion get "Bootloader Code" with Dc-unlocker from OREO shouldn´t be that hard. For me it was much more work to find out which version i can update manually (C02 and C432).

Thanks for your answer. I am trying to find out why some users report that DCUnlocker works and others that it doesn't. In July Huawei patched a vulnerability that allowed retrieving bootloader codes, so I thought this may be the key. But apparently it's not!

hi there, i did the bootloader task in November 2018, at this time, the phone had applied the latest firmware. So it should be beyond July 2018. I suggest, give it a try. The worst that can happen: you may lose 4€. For me it worked with a second try, because i did not follow the instructions correctly. So you need to set USB to manufacturer mode ( see DC homepage ) to allow DC app to recognize your phone. When following correctly, the thing is done within seconds.

[GUIDE] How to unlock bootloader of P7 L10 in 2018 (Without Huawei unlock or paying)

I have attached my unlocking software, if you are still on android kitkat you can immediately unlock and if youre on android 5.0 or 5.1.1 the software will help you downgrade, once you have unlocked the bootloader you can upgrade back to the new software.
Thanks, working trough it on *nix atm, i tried the method described to unlock the bootloader officially, or so i thought, the method has been removed from the Huawei web site. Registering an account was required to obtain the unlock code but this resulted in me having to editing the page to add my country number as the country was not listed to get the sms unlock code.... At the moment i am preparing to hack the device but have not currently found the file for the B856 firmware it's running. I do not want to for example downgrade the baseband, the baseband will need to be hacked a little bit in order to get Android 7.x, i believe is the case.
Rooted my system and backed up all the partitions. Everything but userdata that is,

This software is for the p7-l10 so im not sure if it will work for l12 but it may work, just download it, connect your phone via a usb cable, run the bat file and then choose the option you want from the listed options (unlocking bootloader)
As I can root the huawei p7-l12 the apps to perform this procedure are automatically blocked, I mention it because in the executable root appears necessary.
Hi, I can confirm that this method works for the huawei p7-l12.

Hey, I've tried to get my code but it doesn't work. I have already downgraded and when I open the Get_bootloader_code file and choose the choice 4, it says press enter to continue, I press enter and nothing happens. BUT if I disconnect the device it says step 2 where you have to type your code and press enter. Thing is, I got no code! Please tell me if I'm doing something wrong and thanks in advance!

For this to work you have to be rooted! Make sure you are rooted, and if you are, open up cmd and write adb devices while the device is connected with a usb cable to your pc and give me the output

So I am stuck with this at the moment. To unlock the bootloader, I need to have the phone rooted. And to be able to unroot, I need to have an unlocked bootloader.
I already tried to downgrade back from 5.1.1 to a lower version, but I was not succesfull.
How can I get an unlocked, rooted P7?
That is nice, thanks.
Howeever I need to get back to 5.1.1, while keeping it unlocked/TWRPed, will OTA work, or i need to do incremental flash through TWRP? As i understand doing it by UPDATE.APP would lock the bootloader again?
EDIT: never fk mind.
You know what... DC Unlock really gives you the code for 4€, and it takes 60 seconds.
So after 5 hours of downloading and flashing roms, now I suddenly have TWRP and Magisk after 5 minutes and easy instructions. Couldn't recommend more.

Huawei P8 Lite 2017 Bootloader unlocking

I read somewhere that you can not unlock the Bootloader on any Huawei devices if you have the January 2019 Security Patch Update. Also you can not rollback or flash previous updates. Is this true? I did get my unlocking code before they closed the website. But I did unlock my Bootloader at that moment. So is it still possible to unlock my device?
Thanks.

I tried downgrading my Huawei p8 lite 2017 to Android 7 so I would be able to partition my SD Card as mixed Storage, but the System Updater stops at 5% and the Update fails.
Thats why I assume, that you can not downgrade, but I haven’t had the chance to use HiSuite (maybe this would have done the trick).
Unfortunally I can’t really help you in the bootloader unlocking part, because I don’t have a bootloader unlock code and my old code fails(had to relock my bootloader after bootloop in August 2018).
But I think you should try unlocking if you haven’t already and you have no problem with data loss.
If your phone is boot looping try:
-shutting phone off
-[Dangerous]put phone in freezer for 2-3 minutes (I don’t know why, but this seems to help my phone)
-turning phone back on
still in bootloop: You have to relock the bootloader
---Why My Phone Got Stuck In Boot Loop---
I always had that theorie, that my phone got stuck in bootloop, because I didn’t reboot after unlocking and instantly flashed twrp.
I think there was an error while installing twrp, wich I didn’t notice.
Can someone share the unlock code for Huawei PRA-LA1?
every phone has another code,why you need it?

Unlock code backup??

I unlocked bootloader now I want to flash Pie stock rom afraid that it will lock my phone again how to backup or recover my unlock code which I didn't write down?
Thx!!
How you get the boatloader code??w
You could try flashing twrp then using hurupdater to go to pie
it won't lock my bootloader again right? huawei stopp giving unlock codes now i'm afraid if it locks my phone
btw, which twrp i should use? the one out there seems to be 8.0 i should just use it?
what if I want to flash 9.0 treble roms? i need another twrp after later? thx!
btw, my friend honor 7x (bnd-al10) i want to find stock 9.0 rom for him (https://pro-teammt.ru/online-firmware-database-ru/?firmware_model=Bnd-al10&firmware_page=0) but I don't know which one to download.
the only difference is R1 and R2.
BND-AL10C00E110R1P6B110 (9.1.0.110)
BND-AL10C00E110R2P6B110 (9.1.0.110)
