Hi guys!
I hope you all are well.
I git my P20 Pro and I would like to install a stock android version on it.
I am completely new in this area - I am an iOS switcher
I found already some tutorials but all of them say I would like to need a SD card etc..
Details:
Model: CLT-L29
Build Number: CLT-L29 8.1.0.107(C432)
EMUI Version: 8.1.0
Android Version: 8.1.0
Can you help me?
Not possible at this point, nor would you want to install stock android on this phone. I imagine most people bought this device because of the camera and installing stock android would completely destroy camera performance. Switch back to your old iPhone 6 because that would have better cameta performance than a P20 on stock android.

There are Project Treble (Stock 8.1, see here) ROMs that do work on our device, and with Project Treble comes also support for the hardware of the P20 Pro camera just that uses different software which in some cases (personal preference) works better as it uses less aggressive post processing.
Further to the above, I have tried the Project Treble ROMs (which do boot and successfully function) on our device however at the moment it comes with random rebooting every 10 minutes or so - so steer clear of it for now until this is fixed.
If you want to prepare for when these ROMs fully function - then I suggest that you unlock your bootloader (to do this, email Huawei Support with your IMEI number, Serial Number, Product ID and also the reason for unlock request - I suggest saying 'Development'. Bare in mind that this process may void your official Huawei warranty dependent on the trading regulation authority for your region ) and once you receive the unlock code then you can unlock via fastboot commands which will allow you to make device modifications such as installing ROMs or rooting your device.
Hope this helps
Hi guys
A year and the half or even better just after I purchased my P9 I unlocked bootloader, rooted and went for custom ROM (fRomFuture - NewWorld V4) the only one available and 100% working for P9 at that time as I remember. I got this system since then and I must admit it works pretty well surprisingly without any updates. However I just received work smartphone (Moto G5) which supports dual-sim and realize this is good moment for upgrade my P9. I just took read P9 7.x/8.x ROM's flashing installation descriptions and I feel dizzy....upgrading EMUI, changing partition type from FAT to encrypted ext4..... uff... I already flashed my P9 with custom ROM but back then it seems much much easy with Android 6.
First of all how could I check my firmware version ? With NewWorld ROM I don't see this kind of info.
Second - from what I read I need to update EMUI first from 4.1 to newest ,correct ? Do I need to know my firmware version for that or upgrade could be done (on already flashed system) via Huawei official software ?
I'd like to go for [ROM][8.1][OpenKirin's RROS Oreo v6.0.0 for instance. On Moto G5 I have to install 64bit TWRP and ARM64 Gapps as well - is this the same story with Huawei ?
Make this story short - what step should I take to upgrade my unlocked,rooted P9-EVA with Android 6,TWRP and NewWorld ROM to something newer like even Android 7.x but prefer 8.x because it seems to be working much faster than 7 on my Motorola.
Thanks for help and sorry for lame questions
Flash stock firmware using dload, update to the latest firmware then flash the custom rom you want.
can someone make a rom(Android 9.0) for the locked bootloader version of Honor 9 lite?

Sorry bud but you cannot install any ROM with a locked bootloader, you'll have to unlock it.
Currently there are 2 pie ROMs for our phone cypher os and static os. There are also several other treble ROMs out there. Also you can also get ROMs for Hi6250.
You can only get official updates with a locked bootloader. Considering the fact that emui 9( Android pie) is still in beta for most of Huawei's flagships, we'll have to wait a long time before we even get the beta ROM.
So for now you can use treble ROMs or there are Android pie ROMs in the development section.
But you'll need to unlock bootloader
Hello I have been a lifelong xperia z compact fan, but due to the the awesome camera on the p9 and its similar screen size I am thinking of switching Have some questions that are not clear atm.
- I am used to rooting but it seems that on p9 rooting is only possible with android 6? if i buy a second hand phone with android 8 it is possible to downgrade and root? from what i have read about the p10 it is not possible.
- I noticed that the latest custom EMUI roms are android 7, Is there a big emui interface upgrade with android 8? I am primarly intersted in the camera, with the android 8 is there an improvement in camera quality/camera interface? Do people prefer older versions (6) for battery life or camera quality?
- Someone made the point that these days rooting is less usefull apart from tinkering, the only reason is a proper adblocker, do many users here decide that the latest 8.0 version is worth it over rooting?
- Do any lineage/aosp etc roms have huawei camera ported?
thank you

- Rooting by SuperSU is possible also with Nougat - but SuperSU is no more updated and bacame obsolete nowadays.
Rooting by Magisk is possible with Nougat and Oreo.
Not sure about Marshmallow but Nougat and Oreo definitely cannot be rooted by King(o)Root or so
- If not stuck with the wrong cust, your P9 should be already updated to Nougat (EMUI 5) - even if stuck with, you can rebrand and then upgrade by OTA to the latest stock Nougat.
Only for Chinese cust, P9 will be updated to Oreo (EMUI 8) - but you can also rebrand to and enjoy AL10 c00 Oreo (latest b540 OTA Patch02), with easy modifications it becomes fully 'internetional' (with all languages, Playstore, ready for Google Assistant, international 3G/4G bands, etc) and you can additionally patch Face Unlock (not supported by stock Chinese Oreo, neither by OpenKirin custom ROMs - see further below):
https://forum.xda-developers.com/p9/development/rebrand-update-tool-hwota7-p9-eva-t3820849
- For rebranding and/or rooting you must unlock Bootloader. Code cannot be obtained (and for free) from Huawei anymore, but can be purchased for 4-5 Euros from Ministry of Solutions or DC Unlocker:
https://ministryofsolutions.com/paid-services/amp
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
- There are OpenKirin Treble ROMs based on LineageOS, ResurrectionRemix and Omni Oreo or even Pie - installation requires first to (rebrand and) update to stock Oreo:
https://forum.xda-developers.com/p9/development/roms-openkirin-aosp-collection-t3828806
- Besides the AdAway root app and e.g. Magisk module YouTube Vanced, Magisk might be needed or useful if you rebrand and update to Chinese Oreo.
Namely, you must keep the Bootloader unlocked which blocks SafetyNet (and consequently e.g. GPay - not sure if GPay and NFC are supported and by which OpenKirin ROM, it also changes with their updates).
Hence, Magisk hides the unlocked Bootloader, device shows as certified and passes SafetyNet, and you can use GPay on the rebranded and patched EMUI Oreo.
- With (rebranded) stock Oreo, battery is actually better than with stock Nougat.
Cannot tell you about Marshmallow (used ir only short and long ago).
AFAIK, stock Camera with all its features is not (fully) supported by OpenKirin ROMs (used and tested only one of them for a day or two, and few months ago)
PS: If buying a new P9, you can think of dual SIM L19/L29 - but be aware, unlike single SIM L09, dual SIM lacks NFC reader.
Or even about bigger display P9 Plus - all about rebranding, patched Chinese Oreo, OpenKirin ROMs, etc, also applies to:
https://forum.xda-developers.com/p9-plus/development/rebrand-update-tool-hwota7-p9-plus-vie-t3843930
I recommend getting a P10 instead. But if you can get it for really cheap, the P9 is a very high value phone. Buy phone. Buy DC Unlocker credits. Unlock. Rebrand. Update. Patch. Enjoy Treble and Android O/P.
Thank you so much for the replies guys, yes after doing some more research will buy a p10 second hand, it has a headphone jack, compact screen and great camera very hard to find! unf i read that after a recent firmware update it is now impossible to unlock bootloader from unlockbootloader site .

Be careful (if you plan to do rooting/modding), for some newer Huawei phones, already coming with Android 8 or 9, it is no more possible to unlock Bootloader for free or for 4-5 Euros but only for 30 Euros
And this is not about 'missing that phone from the bootloader codes site, but due to the fact that Huawei switched for them (during the last 6-9 months) to the new and different Bootloader
It might be also questionable what kind of modding is possible at the moment on some of the newest phones with newest firmwares
Not sure does this new Bootloader apply to P10, and does that new Bootloader come by OTA to old P10 phones (better check here on XDA but on the P10 forum)
However, P9 phones do not come and do not get OTA updated with that new Bootloader (even if you rebrand to Chinese Oreo and get its OTA updates), Bootloader code can be bought for 4-5 Euros and modding (incl. rebranding, rooting, etc is possible)
Hello forum.
I am on the latest BTU UK version
Of android 10, but I wish to
return to pie. Do I basically just flash
A pie stock ROM? I Want to
Use the light ROM or galaxy project ROM .... So is it straightforward?
Thank you
GARY
Check current bootloader version if it is higher than on old pie firmware than it is a no go otherwise just use Odin
You can flash Pie, version N960FXXS4CSK2

So...SK1 wouldn't work???
Bootloader version is 5th character when you count back from end of build number. It will be S4 or U4..the number is the bootloader you are on.

Did you manage to return back to Pie?
And do you mind me asking why you didnt get on with Android 10 UI2?
I'm on Pie UI1, and I'm concerned about updating and 'breaking' some of the current features that work on my Note9
Thanks

Android 10 takes a bit of getting used to (so does Android 11 DP1 on my Pixel 3XL) -
I downloaded Odin versions of pie SK1 and latest android 10 build, as well as the twrp for the different OS, have gone back and forwards between 10 and different roms on pie, and no problems, as long as you got backup, odin and a stock rom
I tried downgrading to pie Odin reads everything but doesn't flash. It says write failed after a long time. I am using Alienware laptop I'm not sure if there is something I'm supposed to do. Any ideas. Thanks

This is best your note 9 is on a newer bootloader. it is not possible to flash the old bootloader required for android pie
I was able to downgrade my Note 9 from android 10 to Pie pretty easily, but that was with the 1st release of android 10 for the Note 9. I think the newest version of android 10 has a different bootloader. So you would need to unlock the bootloader before you can downgrade to Pie.

that would be because youre on bootloader 4 and thus can downgrade to the latest pie version on bootloader 4
