Hi!

I see the large number of requests concerning the roolback of a custom rom to a official and untouched EMUI 4, i decide to create this thread.

After follow that methode, you able to rest on official EMUI and get the new update automatically on OTA (directly on your phone) OR try to install custom rom with a clear and good base version.

1. You ave access on TWRP?

-If not, pleas unlock your bootloader (again) and flash TWRP recovery for you actual version (marshmallow or nougat).

-perform a full wipe and restore your partitions on "ext4" format, shutdown phone.

2. Get a "oem_info.zip" for your model phone (dont extract the .zip) and push it on your internal or external sd.

-This archive contain cust and oem info for patched your phone at the correct manufacture information.

-I have a link for VNS-L31 (c432, but is not very important) HERE LINK

-If you have other model (VNS-L31) pleas find a correct patch for you (VNS-L21, ...).

3. Find and download a EMUI marshmallow official full-ota update.

-for a VNS-L31 i advice choice a VNS-L31C432B160 full-ota update.

4. Unpack your update archive.

5. Create "dload" folder on your internal or external sd and put it UPDATE.APP

6. Reboot phone on TWRP recovery and flash "oem_info.zip"

7. Use dload methode for update (hold 3 buttons phone and dont release before "dload screen" appears)

8. Unlock your bootloader again (important!) And make a factory reset

9. Your phone reboot (please wait :)) and done!

Ok now you are on official version, please update on setting menu >> update and choice, rest on official or flash a custom rom..

P9 lite brick precision:

In my personal experience the "p9 lite" is very easy to flash, mod or other tips and the risk of HARD brick is very very tiny.

If you see this page and your phone bootloop, relax, keep calm at 99,999% you have a little and ridiculous brick :)

Good luck and flash happy!

hi! i'm on 381, on my phone i have root, twrp and elite kernel...this guide is good for me???why after dload method i have to re-unlock my bootloader??

thank you and sorry for my english XD
[Huawei P9 Lite Guides, News, & Discussion] Therand:
Yes, is good for you.

Not necessary to re-unlock bootloader.
[Huawei P9 Lite Guides, News, & Discussion] islandman75:
I can do everything up to point 6... won't enter to twrp... stays on Your device is now booting...

Update: I can now reach point 7 but now won't do dload (3 buttons) method... Huawei logo all the time. Can't even turn off the phone
[Huawei P9 Lite Guides, News, & Discussion] Therand:
In my other thread you post the same problem but is not entirely the same..

You succeeded to enter on fastboot mode? Flash recovery?

If you follow the steps 1-5 is impossible to fail the 6 point..

You have acces on fastboot mode or not?..
[Huawei P9 Lite Guides, News, & Discussion] islandman75:
I did update the post... 3 hours ago I wasn't able to enter TWRP, some way I did managed, now I can enter fastboot, I did flash custOEM (sorry I don't remember exactly the name but it's the one of your post) .zip file. Now I can't do dload method, stuck on huawei logo. If I try to go to recovery, I got red message "phone fail validation"...

I know, I post on both but I was trying to do everything...

just tried... validation red error message won't let me go to TWRP now...
[Huawei P9 Lite Guides, News, & Discussion] Therand:
You have a VNS-L31C432?

Your phone does not enter at dload mode?

Wipe all partitions an retry flash a oeminfo for your model phone (if not C432 you need right oeminfo).
[Huawei P9 Lite Guides, News, & Discussion] islandman75:
How can I wipe all partitions if stuck in Huawei logo? Is there a way to do everything from adb command line? (I'm using Mac and cannot use all the tools I've found here XDA neither hiSuite which is basically a backup photo/video only the Mac version).

Thank for helping, really appreciate

To answer your question in the other thread, yes bootloader is unlocked and I am on C432.
[Huawei P9 Lite Guides, News, & Discussion] Therand:
What's your rom have before the bootloop?

You have the right version of TWRP for your rom?

If you have a MM version Don't flash a TWRP for N.

Send me a link to TWRP version used (thread forum)
[Huawei P9 Lite Guides, News, & Discussion] islandman75:
Before the bootloop I was on L31C900 (on the phone) but I did actually flashed C432B160 because I did rollback. TWRP used I've found in the other post where there's a OEMfile to flash (but for this I need to double check because I did look so many pages which I am not 100% sure.
[Huawei P9 Lite Guides, News, & Discussion] Therand:
I not have experience on other model that C435.

But i suggest to find a oeminfo for your variant (C900?)

For TWRP you need flash a version for MarshMallow HERE

Flash it and pas return here (fastboot flash return and first enter to new recovery)
[Huawei P9 Lite Guides, News, & Discussion] islandman75:
Hi, found Windows emulator for MacOs so I extract from update.app boot.img and flash.

I did format all partitions as told using a proper twrp this time.

What's next step, system says NO OS INSTALLED?
[Huawei P9 Lite Guides, News, & Discussion] Therand:
Flash partitions on .img files is not needed.

Just find a corect oeminfo for your model phone.

Flash it on TWRP recovery.

Use dload methode to update on basical version (MarshMallow b160).

After that, unlock bootloader again and make a factory reset.

Switch on your phone (the first boot make long time).

Update on last emui on OTA.

Done!

After that you able to install a custom rom.
[Huawei P9 Lite Guides, News, & Discussion] islandman75:
Done!

Thanks again you're saving my life!

IT won't turn off so been always on it won't keep the charge... Writing so because apparently it won't go to download mode (dload) if plugged in. On the other way if I unplugged from power it won't even start. Shall I force to download mode using console ADB or FASTBOOT? I had looked but can't find anything...
[Huawei P9 Lite Guides, News, & Discussion] Therand:
I not understand.

You not able to switch on your phone without connected charger?
[Huawei P9 Lite Guides, News, & Discussion] islandman75:
Correct. Because I'm not able to switch it off it won't keep the charge. When discharged, the minute I do plug on charge it wakes up... That's the loop...

My main question is: does a command exist to enter download mode using terminal?
[Huawei P9 Lite Guides, News, & Discussion] Therand:
You have a hardware bug?

No abd command to enter dload mode..

Try flash a update.zip with twrp (not guaranted)

After that unlock bootloader again and make factory reset.
[Huawei P9 Lite Guides, News, & Discussion] islandman75:
I'll try. Thank you
[Huawei P9 Lite Guides, News, & Discussion] SebaJudas:

[Huawei P9 Lite Guides, News, & Discussion] anthonybxda:
Sorry for replying to an old thread, but I didn't want to make a new thread since this seems to be a common problem.

I was on LineageOS, want to revert back to stock. Did a full wipe on TWRP (everything but the SD Card). From what I understand I now need to 1) Flash oeminfo, 2) Update via dload method. The issue is, either the oeminfo downloads provided are not flashable, or I am doing something wrong. Can anyone help me?

VNS-L31C432 SS

Thanks in advance!
[Huawei P9 Lite Guides, News, & Discussion] Dadditz:
Hi, :)

if you're referring to my post you're right, it's not flashable via TWRP but via k1ll3r8e's Toolkit.

Switch to stock depends on which android version you're on.

If i'm right you should be on android 7, so use 'HuRUpdater' to do this,

if i'm not, just follow your steps...

Search for that thread...

HERE you can find your flashable L31C432_oem_info single sim.

If you want some help just ask.

Cheers ;)
[Huawei P9 Lite Guides, News, & Discussion] anthonybxda:
Thanks for the quick response. The thing is, my phone isn't being recognized by k1ll3r8e's Toolkit. At least I don't think it is.

Secondly, what do you mean which version of android I am on? I'm not on any version, the phone is fully wiped with TWRP. I *was* on android 7 though, yes.

The current situation is: Device not recognised by adb, and whatever key combination I use, I always end up on eRecovery (stock). I also think that bootloader is locked again, and I cant use SRKToolHuawei to unlock it because it's not recognized/found.
[Huawei P9 Lite Guides, News, & Discussion] Dadditz:
I wiped lot times when i had the p9 lite, never occurred this kind of problems...

so how you lost your TWRP ? why your bootloader should be locked again ?

Dude without booting to fastboot/bootloader mode it may become difficult

to have the opportunity to unbrick, try again...

Turn the device off and keep vol- and power buttons till it boots..

Make sure you have all drivers for your p9 lite on your PC or

reinstall them and try again...

Hi Everyone

my Galaxy s5 got wet in a pool

it was 8 feet deep

after this the screen was totaly black , the phone was dead

i've put it in uncooked rice for one day (20hours)

now when i turn it one , the Samsung logo appear

but after 1 or 2 sec it reboot then the logo appear and it reboot , it repeat the same thing all the time

even when i put it in charge , the battery chargin logo appear and after 1 or 2 sec it reboot

again and again and again ...

The Water Damage indicator still red

i could'nt get into the recovery mode but i could get into Download mode

I need help Please :confused: :crying:
[Galaxy S 5 Q&A, Help & Troubleshooting] Hawaiihemd:
I would first dry it considerably longer, maybe another 48h or so. 20h seems a little short IMHO.

If it stays in download mode reliably, i would flash TWRP via ODIN and try to backup /data/media (manually copy) as well as data to an externalSD and then go from there.
[Galaxy S 5 Q&A, Help & Troubleshooting] thexshoter:
Yeah but when i turn it on into download mode and plug it with the computer

Odin did'nt Find the device

and i don't have some data :(:(:(
[Galaxy S 5 Q&A, Help & Troubleshooting] thereallinkieishere:
I would suggest putting it in isopropyl alcohol. You should have done that from a start after first wetting it. I completely submerged my S5 Active in water without the cover, the display was damaged, and the cameras where screwed. But when I put it in the alcohol for about 2 hours and then in the rice and then left it out in the hot sun, it powered on just fine, only the front camera gives me an error but the back is just fine.

you can always get it on Aliexpress with DHL (4-8 days, costs about 25usd), its probably the cheapest.

I hold power + volume down and it goes in ram dump instead of bootloader...

Since there is no OS and I can't get to Bootloader ADB also doesn't recognize there is a device at all.
[Google Pixel XL Questions & Answers] sb1893:
Similar behavior happened to me when I was running earlier versions of suhide while Chainfire was still correcting for issues in boot process for suhide. I was able to eventually get to bootloader by pressing a key to bypass/skip the ramdump. Obviously you are dealing with a different set of circumstances...but - if you haven't you should try to interrupt the ramdump. (I believe the ramdump screen tells you how to interrupt, but I can't remember it now)

Good luck!
