Downgrade and Lock bootloader - Huawei P9 Questions & Answers

Hi,
I am running EVA-L09C432B378 on my P9. I also have twrp recovery.
I need to send the phone to service because i have (as many others) issues with my gps.
So i need the following:
Procedure for unrooting.
Official recovery.img for android 7.
Procedure to downgrade to android 6.
I think that with the transition package you can lock (not relock) the bootloader.
Can somebody help me?

You dload the Rollback pack .
Then you dload the B136 .
After this Bootloader locked root away. All is Original. Then you Update to B182 and Ready.
Not more. Have fun

Thank you,
I am reading different users have different experiences with different versions of each update. Can you please point me to the correct files for, rollback package and b136?
Also do i have to wipe , format , erase fingerprint data , flash c432 cust , etc ?

Here are the Roll Back pack with 100 mb.
You create an folder name is dload.
In this folder you copy and paste the Update.app .
Then you Power Off Device.
Vol +Vol- Power
Update runs .
After this you delete the dload folder and create a new dload folder and copy and paste all Files from Download Eva L09 C432B136 in the dload folder.
After this Power OFF and same procedur. Vol-Vol+Power and Update runs .
After this you are Happy and wate for Updates to B182 and ....and.....
Ok B136 files comming soon
Here Rollback Pack

[Q] How to Downgrade

Hello Guyz,
I'm running B609 which was 341 mb size. I installed it from b602.
Can u tell me how to downgrade from B609 to b133 ? cause i want to make FULL update from b133 to b609. which is 1.2 gb size update.help me guyz,thanks in advance.
you can do the full update also from the b609 OTA..
just put the update.app inside dload folder on your sdcard and perform a force update (everything will be erased, so backup your data)..
you need also to be on stock recovery!!!
i did it this way and i have no issues so far..

uhm,never.
ok..then you just have to put the update.app inside the dload folder on your sdcard (you might have to create it on the sdcard)..
then do a backup of all your personal data - through the onboard app from huawei)..
after that turn off your phone..wait few seconds..
then you press volume up & volume down & power at the same time and hold them pressed until the screen changes into the "new" emui recovery screen (when i remember right it is a circle with emui inside)..then you can release the buttons and wait for the update to be processed..after that your phone restarts itself and then you should be able to configure your phone
that is all..

Hello
Can anyone help me as to how I could return from B609-B133 was.
B609 installation was complete. 1.3GB, but did not like it.
I would stay in the old Emui2.3. Just would like to come back onto B133.
But in case dload folder copied and three-button start the downgrade does not work.

problems with updating from 612 to 623

Hello there,
I updated my P7-l10 from b620 to b621 with no problems. But when I try to update from b621 to b623 I get a error. I tried many ways (local update and force update), but it always fails "Software install failed!"
Any suggestions what should I do?
how did you update exactly?
you just have to put the update.zip into dload folder and then start updating through local update..
Gesendet von meinem HUAWEI P7-L10 B623
I extracted the zip, and put all the files in the dload
so I don't need to extract the zip?
ok, I put the zip into the dload and updated it. thank you!

Can't update B830 to B853

I have problems with upgrading from B830 to B853. Every time I try to update, it just ends up in TWRP and I will just have to reboot.
I downloaded the update.app from http://consumer.huawei.com/de/support/downloads/detail/index.htm?id=58465 hoping that would work. I have also tried downloading it using Updater (only 70MB there) but the result is same. I thought it would be a fast update for better performance, don't really want to do a clean install at this moment.
Any suggestions? Has anyone had the same problem?
I've got Team Win Recovery Project v2.8.7.0 for HWP7-L10.

Okay, thanks. I will search for it. Would that result in a clean install?
By the way, how's Mate S compared to P7 working out for you? Worth the upgrade?
depends on how you update..
via local update it is not a clean install..by force update it will be a clean install (what i recommend, and after update a factory reset)..
the upgrade to the mate s is worth it, better performance, more features, brighter and clearer display, btw bigger

I may have seriously messed up. I tried to clean install but that still led to the same error. After that I tried to go back to original boot.img and recovery.img using adb but now I can't go anywhere. TWRP won't start (as expected because I flashed recovery.img) and it just says "Unfortunately boot failed, get more information ...".
Need some help.
UPDATE: I managed to get TWRP back but how do I install B853 update.app from there? I can only manage to get to TWRP sometimes, it mostly just reboots. fak
I really need my phone; this is making me very nervous.
I got it installing (this screen http://oi59.tinypic.com/27xhvna.jpg) but after 10 minutes my phone is ridiculously hot and it is STILL verifying update package (loading bar gets stuck 10% from end)... PLEASE HELP ME, I don't have money for a new phone.
UPDATE: managed to FINALLY reinstall B830 thank god. I'm scared to retry updating to B853.

Bootloop

So i rooted my p7 and tried To install custom recovery using flashify and then i got it on bootloop
don't use flashify for installing a custom recovery on p7..use adb tools instead..be sure to take the right custom recovery for your p7 (corresponding to the version of android)..

I know but its stays on 0%. Is there way out
did you put a update.app or update.zip into dload folder on your external storage or internal storage?
maybe this causes the bootloop..
look inside the other threads for a solution..
i don't have the phone anymore so i don' t have a solution..

I got it on fastboot&rescue mode what To do now
connect with pc..let drivers install when needed..then start your command line on windows from adb folder (right click - open command line from here as admin)..
then type:
fastboot devices - this should give you the serial number of your phone
next: fastboot flash recovery recovery.img - replace the recovery.img with the exact name of the recovery you want to have (example: twrp.img - this file should be copied into the adb folder before you start flashing)
after that:
fastboot reboot - reboots your device

Oreo Update Thread - L29C432

Hi there,
here some instructions and files for updating your Phone from Nougat to Oreo.
And how you can try a treble build and how do you come back to Stock Rom.
We start with updating Nougat to Oreo (B321_L29_C636) :
Delete fingerprint and lockscreen pin before you update!
Backup Apps etc with Huawei Backup
Extract the folder of this zip on your external sd card:
https://www.androidfilehost.com/?fid=817906626617955728
and flash oreo_update.zip with twrp.
Then its boot into nocheck recovery and install oreo.
After reboot your bootloader is still open and all apps are still there.
But you need to login to all your running accounts again. Game datas are lost too.
Some things like Themes are not working right now and you have the wrong build number.
We fix that now :
Reboot into fastboot and flash oreo twrp. (fastboot flash recovery_ramdisk twrp_oreo.img)
https://androidfilehost.com/?fid=673791459329072916
boot into twrp, flash supersu for oreo and reboot.
https://www.androidfilehost.com/?fid=745849072291698567
Thanks to "LastStandingDroid" for modified supersu.
Install a root explorer and browse to the following path:
/cust/hw/ rename "spcseas" folder to "eu"
/version/special_cust/VKY-L29/hw/ rename "spcseas" folder to "eu"
/data/hw_init/version/special_cust/hw/ rename "spcseas" folder to "eu"
then reboot.
For VKY-L29C185:
/cust/hw/ rename "spcseas" folder to "meafnaf"
/version/special_cust/VKY-L29/hw/ rename "spcseas" folder to "meafnaf"
/data/hw_init/version/special_cust/hw/ rename "spcseas" folder to "meafnaf"
If something not working well please make a factory reset with original recovery.
https://www.androidfilehost.com/?fid=673791459329071154
flash with fastboot:
fastboot flash recovery_ramdisk Original_Recovery_B321.img
Later i will add the treble part!
Here you can take a look:
https://forum.xda-developers.com/pr...-development/experimental-phh-treble-t3709659
I'm not responsible for any bricks.
Thats how I did it and its working fine.
We solve it with rename instead of flashing data file because it will come request for other firmwares.
I add a Rollback later.
Gesendet von meinem VKY-L29 mit Tapatalk
Everything work for me. If you want make a factory reset after install flash original recovery before. I upload it later.
Gesendet von meinem VKY-L29 mit Tapatalk
Is it suitable for VKY-L29C185 model?
Added rename instructions for VKY-L29C185
Rommco05 said:
Ok if I have acces to internal storage I will tommorow morning install Oreo. Is some chance you upload stock recovery to tommorow morning? Ou, anyway I can extract it from main zip (update.zip)? One more Q, if I flash stock recovery I don't need supersu and basically I can relock bootloader with stock recovery right?

Here is the original recovery but i would not relock the bootloader. Its possible that you brick your phone.

Ok, change my mind I stay with custom recovery but before I make factory reset with stock recovery. Thanks for sharing. I like clean start. Before reset I will rename folders

Hi Blackball. First of all, thank you for beeing here helping us.
I have a little trouble. Of course my p10 plus is making weird stuff. I've downloaded the oreo zip file into my phone, and sent to my SD root (with es explorer pro). Booted on twrp, and launched the zip, but I get an error, zip signature failed, followed by invalid zip file format.
I am on fromfuture b201 . Shouldn't it work with this ROM?

Slightly off-topic question:
I'm considering getting this phone,but,I was curious if the EMUI PC-Desktop mode (found on the Mate 10/Mate 10 Pro) is included in the Oreo update for the P10/P10 Plus ?
At the moment it's not included

Thank you for the prompt response, it's greatly appreciated.
Still interested, considering this vs the Mate 10 Pro.
TBH, I'd seldom find a real world use scenario for the Desktop Mode.
For myself, the expandable storage & front FPR/nav button trump the Desktop Mode, if forced to choose between the two,not to mention the price difference
Will likely order a P10 Plus by the end of the week/upon sale of my Sony XZP.
Once again @Blackball , thank you for the prompt response. :good:
