Downgrading from 5.0.2 to 4.x.x?

Hello guys, i want to know if its possible to downgrade from 5.0.2 to a 4.x.x version? I have lollipop but I've been lucky enough to simunlock my phone after trying out all the guides (i get the menu in the unlockhtchelper app and it says is unlock but after that my phone dont reboot and i try a sim and it doesnt unlock) so maybe downgrading i could simunlock the phone with those guides
Thanks in advance guys hope someone can help me

If you are s-off, it should be possible, although I've never tried it. You should be able to downgrade your firmware to whichever version and then flash the old ROM or run the old RUU.

Rebooting problem after trying to update to Marshmallow

I got a notification that my phone was able to update to Marshmallow today so downloaded the update and set the installation on its way. The problems start here, when rebooting after starting the installation it boots into TWRP, I'd previously rooted my phone but unrooted it after a while, though all I did was select the unroot option on SuperSU and didnt relock the bootloader or anything like that.
The TWRP is v2.8.7.0, and my Moto G is a XT1072 version and currently running 5.0.2.
Im tempted to factory reset but worried that might brick my phone. Any help is greatly appreciated.
Cheers

You can´t update via OTA with a custom recovery like twrp installed. You have to be on stock recovery and the latest full unrooted non-modified stock firmware. Unlocked BL is no problem and doesn´t matter.
In most cases just unrooting and flashing back stock recovery is not enough because there still could be small changes which will make the OTA installation fail.
Nevertheless you can try that or you flash the latest 5.0.2 stock firmware.

Anex to words of Wolfcity, if you want to update via OTA you will need to install stock recovery and stock rom of LP, there is a procedure with a toolkit that you can easily find in general forum. The tool kit will help you to back again at the beginning. Nevertheless, why use stock firmware with a lot of cool roms to flash? [emoji4] [emoji106]

South Korean P9 Plus Nougat Update

Hello!
The main reason I picked the Huawei P9 Plus was that I had read online that Nougat was coming to the P9 Plus. But now, people have had it since March and I still don't have it! lol
So I've got a couple of questions about trying to install it manually.
1) South Korean banking apps quit working if they detect that you have root access. Is there a manual install method that doesn't require root or a way to hide root access from them?
2) Can I install the European update (the only one I seem to be able to find online) on a South Korean phone? I've got the VIE-L09 and I'm currently running VIE-L09C627B140.

The latest for C627 is B140 in Firmware Finder.
You can debrand your phone to get an European firmware. You will find guides here on XDA.

Would that require root or somehow else block apps that check for root access?

You need to do it twrp, so you need to unlock bootloader and gain root excess.
Debrand
Lock bootloader and close root.

I don't think there is a working TWRP for C627. I tried with all versions of TWRP for P9, none of them work.

So is there no way to debrand? Sorry, I intended to test this about 2 weeks ago and then life happened. Stupid life.

I managed to install twrp after flashing the c432 rom following this guide https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523. with the hybrid rom of c900, you can install twrp with SRKTool. After that, you can flash anything you want.

Help with up to date guide to Root

Hi,
Can someone concisely give the most up to date instructions on how to root the P20 Pro
Confused because some people talk about debranding first? Is this necessary if you, like me, just have a generic non-network branded phone?
Also.. Does rooting require twrp?
A bit unclear on if I should use the offical or unofficial twrp methods.
And if so does twrp prevent OTA updates? I was lead to believe that any OTA updates would simply wipe any root and you just have to go through the steps again, but would twrp prevent an OTA update in the first place?
What are the best instructions to root the P20 Pro to keep the OTA updates going (even if you need to reroot after each update).
Thanks heaps in getting through the confusion!

Here you have manual to root in simple 4 steps. You need adb and fastboot on your computer, bootloader unlock code and Magisk from link in post
https://forum.xda-developers.com/hu...de-how-to-root-debrand-remove-retail-t3788326

Does any of the steps,
1/ unlocking the bootloader
2/ debranding
3/ installing TWRP
3/ rooting
Wipe the device?.. I'm assuming yes?
Also. What's the point of debranding?..
I think I'm on a generic P20 Pro that wasn't bought from a carrier - so is that step necessary for me.
Thanks heaps again for the advice - coming over from the Samsung world and maybe I'm so used to the rooting methods there

Also do any of those steps prevent OTA updates?
Or is there somehow to still use OTA updates but simply need to reapply root on every occasion there is ah update?

Unlocking the bootloader will wipe your device. The other steps won't.
You need to have TWRP installed in order to be able to flash Magisk (for Root), and no you don't have to rebrand if you don't want to. You'll still be able to receive and download OTAs but if TWRP remains installed on your phone it won't be able to install unless you change back to the stock recovery. However there is methods to update with TWRP and you'll be able to get and install updates quicker than waiting for them to be pushed to you phone. That's the main reason people rebrand because generic European models are getting updates the fastest.
What's your device model and current firmware version from 'About Phone' in settings?

Thanks heaps for the advice - makes sense now!
I'm using the model CLT-L29 on C636 which I think is the Asia Pacific model.. And incidentally just received a OTA upgrade to the 128 firmware
.. So in order to receive OTA updates you simply have to change back to the stock recovery after using TWRP to install magisk and root?
But I imagine every time the OTA update occurs it wipes root?.. Which would mean reinstalling TWRP to regain root and doing the whole process again every time?

Yep you got it in one lol
The other option so that you don't have to flash TWRP then back to stock recovery each time is when you receive an OTA is download the same firmware (Full-OTA version) from Firmware Finder - you would just need the update.zip - then using Huawei update extractor you can extract the ramdisk.img Then copy the ramdisk.img to your phone, use Magisk manager to patch it then copy it back to your PC and flash it via fastboot. But I think this is more work than flashing between TWRP & stock recoveries haha

Why we need root for 8.0? The download file says no service? Does everthing work? Thanks

For the EMUI 8 to 9 tool you will need root. You can do it from TWRP if you wanted to.
But you will need an unlocked bootloader at least, else you won't be able to install it.
No service = its not a service firmware, as most are on androidhost.ru.
Everything works fine. I just flashed it.

It says "no service" because it's not a DLOAD firmware.

Sorry, i'm just asking... From where did you got the rom? I see nothing on FF

It won't with the EMUI8 tool as it is now.
I will edit the EMUI9 tool and upload it, it will only require unlocked bootloader.
Edit: You can just use the EMUI9 tool as is, it's using Oreo TWRP and Oreo NoCheck.

As I am sure that EMUI 9 comes with new bootloader, is it possible to flash it without flashing xloader? As the Custom treble rom I want to use do not work on 9.0 vendor, so I could downgrade back.
Or uses the EMUI9 the 02xloader? If 02 then I can upgrade it to try it out!

Hopefully the update doesnt come x years laters for the ones on the official beta lol, anyway have fun guys

Unlock phone, flash twrp by pretoriano80, flash Magisk zip in twrp.
Alternatively: unlock phone, patch ramdisk in Magisk Manager, flash patched ramdisk in fastboot.

Would this method work for upgrading BLA-L29c636 b145 to BLA-L29C636E2R1P13B159 (9.0.0.159)

Is there any chance of getting a working TWRP/root on this version?

Great news. I've just installed it without problems. Is there any safe way to unroot and relock bootloader?

Apparently the root developers, amongst others John Wu (Magisk), are working to get a simple way to root EMUI 9.0.
The root has already been confirmed to be working on the Huawei Mate 10 Pro and more devices should join the party sooner or later.

I'm on emui 9 beta and my bootloader and FRP were both unlocked. I removed all the scheme (fingerprint ecc.) ... but when i tred to flash the upgrade with your tool I saw that the FRP got locked. In the Setting options, Developper, (OEM unlock option is not anymore active). How can I restore this options to go on with the upgrade? Thank in advance.
