[Huawei P9 Lite Guides, News, & Discussion] :
Firstly, did you try using the dload method to downgrade?

Refer to post 5. (UNBRICKING/DOWNGRADING/SWITCHING ROMS)

In that post you have explained under EMUI 5 how to downgrade from NRD90M TEST-KEYS.

Please follow the procedure carefully:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

UNBRICKING AND DOWNGRADING FROM EMUI 5 ​

•Use if you are on EMUI 5 STOCK ROM ONLY

•Have a SDCard with at least 4Gb free space

•Best for unbricking or having issues with encryption

•If not getting OTA updates

•Downgrading to EMUI 4.1

•If stuck with NRDM90 test-keys

Note: From my experience if you have problems with EMUI 5 this is the best method to recover from various sorts of issues. It will lock your bootloader (if unlocked) and restore stock recovery because it uses the " Three buttons method aka. Dload method

VNS-L21 Rollback package

VNS-L22 Rollback package

VNS-L31 Rollback package

This file is a rollback package which enables downgrading from EMUI 5 to B160 firmware listed in the 1. post. It will restore stock recovery and also change your phone version number to C900B300 (don't worry about it).

Procedure:​

1.Create folder "dload" (without quotation marks) on the root of the SDCard

2.Extract UPDATE.APP from the rollback package corespondingly to your model number and place it in the dload on the SDCard.

3.Insert SDCard and power off the phone

4.Press Vol+ & Vol- & Power and let the rollback package to flash

5.Power off and take out the SDCard

6.Remove the UPDATE.APP from the dload folder on the SDCard

7.Download B160 update.zip (provided in 1. post) correspondingly to your model number and extract the UPDATE.APP in the dload folder on the SDCard

8.Insert SDCard and press Vol+ & Vol- & Power

9.Wait untill it finishes, you will end up with a locked bootloader (if it was unlocked beforehand)

10.I recommend rebooting to ERecovery (Vol+ and Power) and factory reseting

11.You will end up with stock EMUI 4.1

12. Update to EMUI 5 using the official updater inside Settings

And this will work even tho i have replaced my recovery with twrp?
[Huawei P9 Lite Guides, News, & Discussion] :
Yes, it doesn't use the recovery. It uses the secondary ERecovery. You enter it by powering off your phone and then by pressing all three buttons (hence the name).

I tried a roll back package but it says its not compatible (my phone says on the back L-31 so i got the L-31 software) then i tried a emui 5 update(i think) still the same and a emui 4 update still the same so i tried a L21 rollback package but that didn't work either the dload comes on says indtalling but tyen says its incompatible my phone os is nrd90M emui 5 but but oem info and cust are for emui 4 i cant use a pc as the phone says i dont have perms and the method you suggested did not work what else is there to try?
[Huawei P9 Lite Guides, News, & Discussion] :
So... try again with a another sd card, if not use the same. Use the L31 rollback package and even if it fails, after that dload B160 for L31
[Huawei P9 Lite Guides, News, & Discussion] bghyt:
i keep getting "software install failed

incompatibility with current version please download the correct update packedge" :confused:
[Huawei P9 Lite Guides, News, & Discussion] :
From what i remember you can enter TWRP?

Find the OEMINFO.zip that is working for your model and flash it. Then try dload method again.
[Huawei P9 Lite Guides, News, & Discussion] bghyt:
i probaly can't find the oem info but i will look, and i cannot enter twrp only erecovery and do dload fastboot will not let me update that way because it says its missing android.txt in ther update zip

---------- Post added at 05:21 PM ---------- Previous post was at 04:58 PM ----------

i have a backup of the phone from twrp which has "oeminfo.emmc.win" and its md5 can i do anything with that and the cust and dload that into the phone?
[Huawei P9 Lite Guides, News, & Discussion] bghyt:
I found the oeminfo i think it's here its single sim (ss) if you could give me links to the update.app packedges for them it should fix it or if its possible i could flash a update.app with nougat nrd90m oeminfo and cust

[Huawei P9 Lite Guides, News, & Discussion] :
Whoops, it seems that this OEMInfo is not TWRP flashable...
[Huawei P9 Lite Guides, News, & Discussion] :
So... Unlock your bootloader even if it shows that it's unlocked.

Also, to flash the OEMInfo you mush use the P9 Lite Toolkit

Thanks for your reply on PM.

As I mentioned earlier that I read thru your thread, but unable to find the exact answer I was looking for.

Currently my P9Lite is using VNS-L31C636B170 ROM EMUI4 and whenever I tried to upgrade to the latest nougat EMUI5 release (VNS-L31C636B389) I will receive an error at the dload menu (Vol+/- & Power).

Can someone point a pointer to me how should I be going about on this, it seemed like I am missing something.

Many Thanks!

Do it in smaller steps, is there a older EMUI 5 update to start with? Like B370?

Everything is alright but I don't know what to do

Hello people.

I'm trying to root my P9 lite (EMUI 5.0) by following the instructions but I'm stuck because I don't know how to proceed.

This was my process:

1. Unlock the bootloader (already done) and go in fastboot mode.

2. The toolkit recognizes my phone.

3. I go to Recovery > Individual > Select the TWRP Venus image and press "Flash Recovery".

4. The toolkit tells me that it was successful and asks me if I want to reboot into Android. I press "Yes."

5. I reboot and the I go back to the "untrusted device" screen and I press the volume button for 3 seconds and it goes into recovery, but it's the normal EMUI screen and if I reboot I go back to EMUI like always.

The instructions say "Reboot to recovery", but as I do, nothing happens. I am obviously missing something, but I can't figure it out, what could it be? TIA.
[Huawei P9 Lite Guides, News, & Discussion] tw1st3d83:
Disconnect your device from pc and then reboot in recovery with holding volume up and power button...

Or with connected to pc go in adb folder, hold shift on pc keyboard, right click on empty space in adb folder and click "open command prompt here" then type "adb reboot recovery" without quotes off course...
[Huawei P9 Lite Guides, News, & Discussion] M.B.V.:
The first method doesn't work.

For the second: does my phone have to be connected while on fastboot? Where does the adb folder have to be?

P.S. Reminder that I am on Nougat and the process may differ if you were on Marshmallow. Maybe it's better to downgrade because it's easier on EMUI 4.X?
[Huawei P9 Lite Guides, News, & Discussion] :
Stop.

Are you sure you flashed the TWRP meant for EMUI 5?

Second:

Boot up your phone.
1.Open dev-options and enable usb debbuging
2.Install adb to your pc using the "5 second adb installer" linked in the post 8/9 (not sure)
3.Open cmd and type:
adb devices [press enter]
4.Confirm authorization on your phone
5.Type in cmd:
adb reboot recovery [press enter]
[Huawei P9 Lite Guides, News, & Discussion] M.B.V.:
Already had done the ADB Installer thing. Did it like you told me to now instead of using the Tool, it took me a bit but it worked! Thanks.
[Huawei P9 Lite Guides, News, & Discussion] Derpfestor:
Ok people, I somehow fixed the oeminfo issue somehow, tho im stuck at global version instead of asia variant.

I've done 3 button methods , twrp ,dc phoenix, adb, SRK. All of them, I have no idea how it got back to VNS-L31 but it did.
[Huawei P9 Lite Guides, News, & Discussion] :
Flash asian OEMinfo and Aisian firmware through dload to restore it, even tho I would recommend the eu one, it gets the updates most frequently.
