Hello Xda ,
I just bought a p10 few weeks ago , and yes i've just root it by doing OEM unlock , install twrp , flash the root images and i have rooted my p10 .
few days later system update notify me which is **********B133 , i had figure out how to update manually because OTA update wont works on rooted device .
so , i install the update using twrp flash the update images and yes i 've done the update also .
But the problem is after i updated my phone , the root is gone , so i have to re root the device , but in order to root the device i have to wipe to factory reset .
The question is ,
1, is there anyway to update system without losing root ?
2,is this update really useful for the p10 ? for p10 rooted user did u guys update ur phone to latest firmware ? If yes , how u guys do it ?
3, is there anyway to relock Oem without losing root ?
4, is there any software/apps that can update firmware beside flash the img ?
Thanks for your kind assist.

no updates recived, is this normal?

Hello
EMUI 6 will be out soon, but my P9 + is still under EMUI 4.1.1
I have a VIE-L29C185B181 and I have not received any updates, (from HiCare or update)
I have tried manual updates (B360, B380, B381) but it does not work, and the B320 is no longer available on HiCloud.
Is it normal or my p9 + has problems?
thank you

if ur bootloader and oem update are both locked (i.e u are on stock unmodified android 6 and emui 4.1.1) use firmeware finder to upgrade to l29c185b360, then use it again after upgrade to upgrade to 380.

- my bootloader is unlocked, is this the problem ?
- If I do a backup of oeminfo, can I do a rollback to M from N with this backup ? I have tried this method with other device (Huawei G8) and it work.

I have reinstalled C185B181 for locking the bootloader,
then I tried to install C185B360 (method 3 buttons and method *#*#2846579#*#*) with locked bootloader and unlocked FPR but it's fail @ 37%
then I tried with locked bootloader and locked FPR, also fail @ 37%
finaly , I tried with unlocked Bootloader/FPR and also fail @ 37%

try using the firmware finder method with firmware finder proxy module. no need to download the firmware to ur phone before upgrade...just select the firmware u need to update to in firmeware finder and select update via proxy, then go to about phone and check for updates and then choose install full package. make sure u dont have an altered system to begin with and no root, no problem if both bootloader and fps are locked.
also dont forget to choose OTA/FULL package to update to.

thank you for replying
Just a question, is C185B360 an official update for C185B181?

yes it is.

dont forget to remove dload folder if u have it in internal or SD card.

I tried with Firmware Finder 2 times but it's fail @ 2% (download 100%, installation 2%)

I have also tried to reinstall the C185B181 (current version of my P9+) with Firmware Finder but it's fail @ 2%

sorry I have no more suggestions, that method worked for me at least.

Is it necessary to upgrade to B320 before B360?
If yes, is there anyone who has a copy of C185B320 ? (this version has been deleted from HiCloud)

I do did it (sorry for my bad english)
C185B181 -> C185B360 -> C185B380
the bootloader most be unlocked

[HELP] How to Downgrade & Root my Nokia 8 properly

Hi everyone.
I just bought a new Nokia 8, but it's on Oreo. I want to rollback to Nougat and root it.
However I saw many things here on xda and I fear to mess with my phone.
So first off all, here are some details of my Nokia 8 :
- Model TA-1012 (64GB/4GB RAM)
- Oreo 8.1.0
- Security update December 1, 2018
- Kernel version 4.4.78-perf+
- Build 00WW_4_88B_SP07
_______________________________________________
Downgrade :
I've downloaded 2 firmwares :
NB1-484A-0-00WW-B03.nb0
NB1-4390-0-00WW-B01.nb0
Problem 1 : I don't know if there are Nougat 7.1.1 firmwares, so if anyone can confirm it ? ALso is it good for TA-1012 model ?
Problem 2 : I also saw the same firmwares but with "QFIL" at the end of filename. What is that ? Is it necessary ?
Problem 3 : How to downgrade with firmware like these ?
Unlock Bootloader :
I know that I have to unlock my bootlader, but I heard that there is a critical mode, how to do it for my TA-1012 ?
I saw this topic but I don't think its about critical mode https://forum.xda-developers.com/nokia-8/development/official-nokia-8-bootloader-unlock-t3848051

How to ROOT my phone ?

Thank you in advance guys, I love that phone too much to brick it :laugh:

Why to you want to downgraded the phone? Is nougat better is performance or battery?

On all my phones, the most old firmware is always faster and less battery consumming than the last (I measured it).
But right now, I've succeeded to unlock my bootloader offficialy. However, when I tried to boot TWRP with Fastboot boot twrp.img, it's stuck on Android Logo Of course I can reboot my phone but I can't flash TWRP...
Is it becasue of 1st December update ? is it because bootloader isn't critical unlocked ? Or becasue of boot a & boot b partitions

Apparently it's because of December Security Patch...
Can I downgrade my phone to nougat to be able to root it ???

Lock bootloader again with oeminfo to try the warranty repair

Hi, unfortunately my p10 drop on the floor from an high of 8 cm... Yes almost 4 in an the camera now has a strange yellow border. Of course this issue happens only on the color camera. The b/w camera works well.
The problem is that I have unlocked the bootloader. Can I do something to prepare the phone for rma?
I've the original oem info and of course the unlock code.
Thank you in advance

Maybe downgrade to nougat and then ota update to oreo will help. When I made debrand had unlocked bootloader and frp. Then did ota update to oreo and now have bootloader and frp properly locked.

What guide should I follow for this?

For debrand I used this guide:
https://forum.xda-developers.com/p10/how-to/huawei-p10-debrand-rebrand-update-guide-t3691013
but I was doing it on nougat and I am not sure how it works with downgrading from oreo to nougat.
If you are already on oreo (and C432 region) you could try to use this guide :
https://forum.xda-developers.com/p10/how-to/guide-manual-updgrade-to-update-oreo-t3758286
tutorial 2 to flash the first full-ota oreo 8.0.0.360 from: http://pro-teammt.ru/firmware-database
but here is question to @Jannomag if it's certain that the script will work from newer to older oreo version. If so then try to use HiSuite to downgrade to nougat (for .360 it should be possible when hit firmware update -> switch to other version) and finally do the ota update to oreo. Be aware that I am not absolutely sure it will work, just suppose it should.

Downgrading to a lower version as Dec2018 security patches can be indeed a problem but this shouldn't cause a brick. The updated should fail flashing /kernel and /ramdisk from update files.

I tried to flash B365 oreo over B384 with tutorial 2, update started as usual then reached 100% and phone switched off totaly. Now looks like bricked, can't switch on, charging doesn't work, when connected to pc system shows unrecognized USB SER device. Is there any hope to unbrick it?

I have the same. Send to warranty and they fix this by replace the Motherboard. Now i can't unlock bootloader because no offical codes and DC unlocker not support newest security patch from Huawei. Otherwise Phone works fine and i have extra warranty to 2022 .
