How to update Huawei Mate 20 With Locked Bootloader - Huawei Mate 20 Guides, News, & Discussion

Hello guys,
I saw on the forum of the M20P that there's a tool used to update the device using a locked BL.
I wanted to know if anyone of you tried this, and if yes, can you tell us the result
I really don't know if this method could actually works on our device...
There's the thread link : https://forum.xda-developers.com/mate-20-pro/how-to/manual-upgrading-mate-20-pro-bl-locked-t3905924
Thks guys for your help with the community :fingers-crossed:

I'll answer to myself,
I tested the method just above, and yes I managed to update my M20 to 9.0.0.237
I followed this tutorial video : https://www.youtube.com/watch?v=bp4k3uFDxf4 , and i used the tool listed on the thread I linked in OP.
There's a screenshot of my phone showing the version and the security patch I have now.
For the next updates, you have the choice guys, you can use Firmware Finder app on the playstore or use this thread https://forum.xda-developers.com/mate-20/how-to/guide-manual-updating-firmware-t3892686.
BTW, thx to @OldDroid and @mikeos for their amazing job

I have HMA-L09 (single SIM) C432E10R1P16
Vodafone brand on the box, but software is unbranded, no vodafone crap stuff nor bootlogo, infact is C432
Just after turning on after hard reset I saw something branded, but 100% uninstallable
So, should I upgrade with this method, I'll definitely get rid of brand? and will I lose my data?
Of course I have locked BL, I used to have rooted phone since my first Android 2.1, so sad

Root and Cyanogenmod

Hi all! I recently got a Huawei P9 vodafone branded (L09C02B123) and I am very happy with it. I wanted to ask if there is a safe unlock bootloader and root guide for this version or do I have to de-brand it? And if I wanted to unroot the device can I go back to the vodafone version as it first was? And since I don't like the MIUI software (the only downside) when will the CM 13 roll out to the device?
Thanks

Hi.
Please download the SRK Tool. It can do almost anything you need on your phone.
Wrt the custom ROM, you asked, unfortunately we only have one custom ROM and one slim ROM atm.
What i did was, root, debloat the ROM myself, flash a 3rd party launcher, and flash the L Speed app from Play store.

Thanks for the answer. Your method is smart but do you know when Cyanogenmod will be launched?

Cyanogen Mode is quite different from stock version of the p9 software or variants of it. Drivers would be a great issue in that way. Since the Kirin 955 processor is relatively new and not as common as Quallcom's Snapdragon, there would be a long long way to see a Cyanogenmod for our p9s.
However it is a job for ambition and determination. So, who knows maybe one of the great developers around will take a step forward
Hi guys again, I remember I am running the EVA-L09C02B123 which is a vodafone branded version. Can I root this version? I heard that you need to de-brand it first. Is it true?
You can root it without de-branding but you must unlock the bootloader first. That's going to trigger a factory reset, so back up your stuff.

Install EMUI 5 on EVA L09C521B140

As the title says, how can I install the android 7 OTA on my P9 EVA L09C521B140? In the post http://forum.xda-developers.com/p9/development/rom-stock-rom-eva-l19c636b168-t3419586
I saw that the OTA for NXT-L09C521B140, it serves me the same? In what changes?
Thank you very much
I'm interested in this as well. I'm assuming you're interested in unbranding your phone as I am? Got it from a carrier, right?
If you find out anything regarding this please do let me know.

That post is old and it hasnt been updated it ages, if you want to know the latest firmware for your C521, best to download an app called Firmware Finder and check in there, B361 is the official released Android 7 firmware.

Hi, thanks for replying.
This is only the second day I have this new phone. I got it from my carrier so it has their brand at boot, the crappy bloatware they tend to put etc.
What I would like to do (at least until the devs manage to release a stable CM version for the phone) I'd like to get the OFFICIAL stock rom (unbranded, like bought from a store)
Could you point me somewhere where I could find how to do it, where to start etc? I'm all for learning myself but a start-point would be nice.
If I'm not mistaken, the model is EVA-L09 so C521 would be the variant? and B140 the firmware version, correct? And what's with the "cust" version at the bottom? carriers firmware?
Also, I've been reading and apparently NOUGAT is still in beta for these phones? So I guess I'd like to update to latest MM, and then update whenever they decide to release OTA.
Thanks in advance.
EDIT* TL;DR, Basically, I want to unbrand the phone. Remove my carriers bloatware. Just like a store bought phone.

If you look through the guide section of this forum, you will find what you been looking for. If you are looking at debranding and getting on to Nougat, you can follow this guide. Also, Nougat (EMUI 5.0) is now being officially rolling out but at a very slow pace.

[Q] Nougat method for EVA-L19C605B135

Greetings, I bought today a new Huawei P9 (EVA-L19C605B135).
Looking around xda and other forums, and I couldn't find any guide or hint to make this particular build update to Nougat.
I read that is able to debrand this phone (I don't what that mean and how to do that btw) and install a custom ROM with the latest firmware... my question is, can anyone could guide me through this process? do I need to unlock bootloader? roo? twrp?
I have it just out of the box.
Please, I would really appreciate any help guys, I'm new at huawei. (had a moto for 4 years, stolen last week)
Thanks in advance. Just need a little push.
EDIT: NEVERMIND! Just got the official nougat update, thanks.

Android 8 and P8 lite 2017

Hello, I have some questions about this phone, it will be long ...
My old Xperia XZ died after a foamy party ... so I bought this phone, and it's pretty cool.
So I would now go to android 8, surely LineageOS or EMUI8 I do not know yet.
So, do I really need to rebrand my phone for project treble?
Some links say no, some Rom allow activating treble, and other links say that you have to go through the official Rom EMUI8
I have to use EMUI recovery or TWRP?
Where can I find EMUI8 for Huawei?
How do I unlock my boot loader?
because the links I found his death ...
It was a lot easier on Xperai: D
Thank you for your help, as much on Xperia I know everything but there I am lost with this different recovery, with EMUI ... with the trick honor / Huawei
And I'm french, so not sure that I'm very readable, do not hesitate to tell me
Hi,
Just wait a little bit it should be Rolling soon in all countries officially (UK, Spain among others countries already got it so it might be soon for France )
If you're really in hurry there are multiple guides here that explains different ways to update manually. Not sure though if you can still unlock the bootloader...
Salut!

Tks,
I have bought this phone in spain so i hope i will have the update soon.
But, i want to change my rom because i'm barely out of storage, so i want a debloated rom like lineage not sure EMUI8 will fix my prob...
anyway I do not think I have enough storage to download it... they only have the 16go at movistar.

Yeah its too late for bootloader codes, huawei closed it a few days ago. Unfortunately you cannot flash any custom roms/recoveries/kernels, and i doubt anyone will ever crack the bootloader. sorry mate.:crying:

You can try DC unlocker but its expensive, google it.

I'm baffled. My sim-free UK device still hasn't got the update whereas seemingly everyone else has.

you can get your bootloader unlock code via dc-unlocker it's a paid software but it works​

Question Need advice for the G998U/DS and living in France

Hi guys,
I need advice for the s21 Ultra that i bought on Rakuten. In the description the seller said it was an international/US version and at this time I didn't know that it could cause problems knowing that I live in France. I have the G998U/DS version
For now the phone is working perfectly. I don't have all the problem i can see in other thread like the broken GPS, a poor network, wallet broken etc. Everithing is ok.
But i need advice for the last update with Android 13. Actually i get the Android 12. And of course the phone does not offer me any updates. I know this is because i have a US version and i live in France.
So question 1 : Do you think I will eventually get the update in the future ?
Question 2 : If I install the update by flashing the phone, won't I have all the problems that others have with this us version and living in France ?
Thanks for your support fox.

Hi,
If everything is working out of the box, then you shouldn't worry much. It's always better to install the update via OTA. It doesn't matter where you live/use the device, as long as there's an update for your device (Snapdragron chipset and CSC), it should automatically show up. If you want to install the update manually, then it's better to download the official update via Frija and install the update via Odin.
Hi,
Thanks a lot for your answer. It help me a lot.
About the update, i read everywhere that where we live/use the device is impact the update. For now i don't have any update that show up. I am in Android 12 and i should have the android 13 update.
Lot of people said that i probably never had the update because it's an import us version and live in France.
What about that ? Do you thinks i will get the update in the future ?
Thanks again
It seems you are on a March update. I have a feeling your device's was a locked device which was then unlocked...I could be wrong through...https://samfrew.com/model/SM-G998U/ Here's what I could pull up regarding your device's update. You need to careful on which file you download as I don't see any OXM ROMs for US devices...they are provided by carriers.
Ok,
I think in my case, update will not be possible. I'll stay in Andoird 12 until next phone. Never buy again in Rakuten ahah.
Thanks for all your help.
Remove SIM, use VPN to connect US and try update over wifi.

Just try and not working but that was a good idea
When i chek on Frija, he give me this :
What do you think about this update ?
Edit : this firmware contains these files
If you are sure of the CSC, go ahead. The reason is yours is not OXM rom so you have to be extremely careful when choosing the files.

Ok, thanks, i think i'll do the update.
To be sure, you mention a OXM ROM but i can see that i have o OYN rom like you see in this screen :
I really can't place the device's region. There's no region called GCF in Samfrew. I feel it's a subset of another region. Dunno
Finally I did not dare to flash my phone, I am too afraid that I can not use it anymore
Anyway, thank you very much for your help
