Lenovo Yoga 2 1050L firmware needed / Error when installing the latest update

Hi guys,
I hope anybody can help me. I'm looking for the latest firmware for my yoga tablet 2 1050L.
It should be YT2-1050L_USR_S100255_1601131716_WW52_ROW. At least that is what the OTA message shows me on my tablet.
After softbricking my tablet (was stuck in lenovo boot logo) when I installed this OTA update (162MB), I was able to recover it with firmware S100192. I checked also for country code and set it new. When I now try to install the OTA update I get an error and can only boot the tablet again and it wants me again to update to the S100255 firmware.
I also looked in the russion lenovo forum (you can translate with google into englsh or my case geman)
http://lenovo-forums.ru/forum/395-yoga-tablet-2-10-%D0%BF%D1%80%D0%BE%D1%88%D0%B8%D0%B2%D0%BA%D0%B8/
But there is the latest firmware I can download S100192.
So I would need either the S100255 firmware to flash it from stock or anybody can give me an hint in how to solve the udpate error

you cannot skip ota's, they are cummulative

Hi ionioni,
ok. what do you mean exactly? I don't want to skip it. I want to update it but it's showing error while the update process. and then when I am in Android again it wants me again to update to S100255. So I thought I could flash it with the latest stock rom S100255.
At the moment I try to flash an older stock rom like S100081 or S100225 (and then doing OTA hopefully) but whenever I try to flash it it boots into Android again when it should
C:\Program Files (x86)\Intel\Phone Flash Tool\fastboot.exe" "-S" "500M" "-s" "BaytrailABFF4CD2" "oem" "wipe" "ESP"` command

your initial message was a little ambiguos...
before flashing a stock rom go in Contacts and in the search contact box input ####0000# and tell me what he says under BIOS version

ok, you can flash a lollipop stock rom as you have the matching bios
first uninstall the Intel Phone Flash Tool you have now and install the one from here
then you can install using your stock lollipop rom if you have one or using this (if you download this flash it from DnX mode)

OK, I don't know why but it seems to be a problem within my office. I downloaded it at home and there I have no CRC issues.....
I will try to flash tomorrow than and hope it works. DnX mode is booting with both volume buttons into fastboot, right?

Ok, now I was finally (!) able to flash it and to boot it into android. Strange issue when I extracted your zip file on my HDDs on my company's notebook I got a zip CRC error. I unzipped it now directly on my USB drive (connected to my company laptop) to my external HDD and I had no issues. Only the devil knows why...???!
So after using your phone flash tool lite version 5.3.4.1 it worked now. I'm just downloading now the next OTA update over WLAN to version S100192. after that version S100255 should appear. let's see what happens Thank you so far.

no don't think it's EOL as it was on both my harddisks and I have no problems with other files. Don't bother anymore.
Good news: was able to flash and update it OTA to the current Firmware S100256 (14MB) which has been released as there may have been some bugs to the S100255. and it works! Thank you very much! :silly::silly::good::good::good:

Sorry for bothering you, but I have same problem as Iceball24. Could you tell me what should be the settings for Phone Flash Tool to flash yoga properly?

Maybe this can help you:
Make sure you use the latest Phone Flash tool (lite) which was 5.3.4.1 for me. Make sure you use a USB port at your laptop PC, don't use a hub (did not work for me). And If you are not able to flash it via the DnX mode (press both Volumen buttons and power on the tab) then try using the Fastboot mode in the bootloader (volume down and power on the tab).

Hi ionioni,
I'm back with a further problem. I just tried to start teamviewer on the yoga. I get an error that the firmware may be faulty and I should check for a proper IMEI. So I put in a SIM card (which I have used in anther phone) and I'm able to unlock it with the pin. But I get no data connection and also when I try to set a new PIN for the SIM card in the security settings I enter the PIN and it says wrong PIN I have 3 more trys. but I can try it as often as I want, it does not lock the SIM card.
So what may be the problem? any ideas?
UPDATE: Ok, just checked my IMEI online and it appears to be an IPHONE IMEI??
Update 2: Under settings, network, more, mobile connection (? just know the german word for the settings) I can not choose the menu as it is deactivated and grey. I just read that the tablet may think it is in flight mode?

New Firmware 5.0.0-RU1.1.99

You can find it here: ftp://fw.ydevices.com/YotaPhone2/Firmwares/RU/
Install either via OTA update if you're already on the 1.87 RU ROM like I am. On my device it first wanted to install the update only, about 67MB, but it failed to install; then the next time I checked for updates after reboot through the settings update menu, it downloaded the full file, about 0,99 GB. Then the update went all the way through. SuperSU is lost on the way, I will try if it still works through the recovery installation.
You can also install through Yotaflasher like it's explained here: http://forum.xda-developers.com/showthread.php?t=3247356
Didn't have time to test things out, but it's still Lollipop 5.0, so only bugfixes and some new yotapanel features I guess.
Enjoy!

Thanks for that muchly dude, hadn't checked that for a while.
Update seems to be stability improvements, power efficiency improvements and some yotamirror and panel improvements and features.
Its not 5.1, but it's an update, I'll take it.
And yeah, super glad moved to the RU ROM. Backing up now, will OTA flash update once that's done. SuperSU has been flashable everytime after an update so far so fingers crossed.

All up and running .
I was rooted, running RU 1.87 with TWRP - phone handled it all just fine - downloaded OTA, pressed install - it went to TWRP > flashed stock recovery back over itself > rebooted and installed.
Phone booted up, all working fine. Lost root - simple reboot and flash the SU.zip had sitting there from the last update. Cache and Dalvik wiped for good measure.
Reboot and all is well and back to normal but with a few improvements, lovely.
About as easy as it's even been done really.
Hope everyone else gets to enjoy the update through similarly smooth procedures .

Yeah, I ended up doing a fresh installation plus rooting, everything smooth. I'm never too sure what an update leaves behind.
It's really a great device, hopefully they'll keep updating things for a while. Of course version 6.0 would be welcomed... Apparently, by the numbering they use, next step would be either 1.2.xx with Android 5.1 or 2.x.xx with 6.0. Let's see.

Fair play, I toyed with idea of it, but was fresh from last install and honestly don't have the time to set everything up again.
My hope is they take all their good ideas from this and can at least join someone else in making a great device.
Saw a working bendy phone the other day, lets you turn pages on reading app by bending corner as you would a book etc. I thought if that could be combined with yota tech, then you have damn near the perfect tablet.
Honestly I don't think we'll get 5.1, let alone 6.0. They're refining their ideas in prep for Yotaphone 3, that and the possible tablet are their main focus right now.
Interestingly, the update flashed it's stock recovery over twrp - someone prepared for the possibility of root owners this time around. So they are still paying attention .

So any idea what's the difference between the EU and the RU rom? I mean there has to be some reason they are two separate roms.

To answer my own question: there isn't too many differences between EU and RU roms. I did a diff between the RU1.1.59 and EU1.1.60, and out of 2092 files, roughly 1900 of the files inside system.img were identical. The APKs were slightly different, but only slightly. So probably the difference comes from some differently named resources.
The RU version also has some additional apps which the EU version does not have, such as Esquire, Questions, Strelka and Vector. These are probably the main reason why they have different ROMs. They might only work in Russia.

FYI the difference is essentially the product package configuration (app bundles that are pre-loaded) but there are also some differences between the resources used for the stock apps. One in particular (my personal fav ) is the dialler - the RU variant includes cyrillic characters regardless of language/locale setting (feature). The EU will give you a regular english-only dialler if you're using english locale settings

i'm using this post as a minimalistic guide for myself (so i keep it up with my "discoveries" )
and ofc for been helped by everyone who wants to help me because i am completely new to android world cause this is my first android phone ever!
so.. let's get started!
i downloaded [TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer v1.4.3
version 1.4.3 doesnt works for me so i downloaded the 1.3 as suggested and worked.
then i enabled the download mode following the procedure:
Turn off the phone, then press and hold the volume down key + the power key at the same time. This should boot you into download mode.

*is installing TWRP a mandatory step?
EDIT: the answer is NO. it seems that the mandatory part is to unlock the bootloader (the bad part for the warranty.. and that can erase ur data..) and this can be done following this guide How to Install TWRP Recovery on YotaPhone 2 untill point 6 included - which i am reporting here for easy of use.

How to Flash TWRP Recovery on YotaPhone 2
1 - Setup ADB and Fastboot on your Windows PC.
2 - Enable USB debugging from developer options on your YotaPhone 2.
3 - Connect it to PC with a USB cable, if it asks for debugging authorization, permit it.
4 - Go to the folder where you downloaded the TWRP recovery image from the download link above on your PC and open a command window inside that folder by doing “Shift + Right click” on any empty white space inside the folder, then select “Open command window here”.
5 - (Skip this if your bootloader is already unlocked) Now to unlock the bootloader, type in the following command:
└ Beware that unlocking the bootloader may wipe your phone’s data. Make sure to backup first before proceeding.
adb reboot bootloader

└ This will reboot your phone to bootloader mode

The info is described in various posts across the yotaphone forum. Are you rooted? If not then there also many many guides across the internet for that.
Not walking you through the whole process, sorry. We all had to learn, once you do it's all much easier.

It happens also to me...don't panic! press Volume up and the power button and when you enter in the bootloader select the downloading options, it will restart the phone with the "downloading" status
in the meanwhile with the yotaflasher select the option to downloads a firmware and try a different one. When the download is finished try to flash once again.

I placed like you the rom downloaded through website in the firmware folder and flash got wrong. I was blocked on "powered by android" logo like you.
After this almost-bricking experience, I flashed 4.4.3 downloaded all through Flasher and phone was working again.
Then I tried to substitute 5.0 system.img in the folder downloaded through Flasher but no way... after flashing phone didn't boot.
I reflashed 4.4.3 back again and now is working.
I think that we can't put files in folder for Yota Flasher...
I cannot download last 5.0 EU version, like described here: http://forum.xda-developers.com/yot...ially-dead-t3312382/post65839167#post65839167

*i checked for update on the phone in setting--> about phone --> sistem update
*it downloaded lollipop (android 5.0 Lollipop - 1Gb to download) :laugh:
*i took the 5.0.0-RU1.1.99.zip and flashed it
*u can choose english when the phone boot so dont worry about firmware to be RU
*i checked the firmware version doing the combo "Volume up and the power button" (press it while restarting)
*i changed the language of the phone in setting --> language (there is plenty of languages to choose. i choose mine, italian, but sometimes it happens to find something in english )
i downladed some app etc etc but i never used it for calls cause of the requested nano sim that i'm going to take tomorrow probably cause today i get stucked with trouble about my contacts.
hope to solve the problem for pass my contacts form my nokia N8 to yotaphone 2 quickly!

I haven't updated this morning because I was downloading a previous 5.0, the EU 1.44, but when flashing I had error "cannot load firmware/system.img". So I reflashed 4.4.3... I'll try again this evening

Hello! I have 5.0!
After flashing and old version of 4.4.3 (my phone went with a 4.4.something branded Vodafone Italy, and they evidently don't give a fork about updates). With the 4.4.3 rev 1.0.51a I immediately received he update to 1.0.56a: I downloaded the 114MB, rebooted, and then got the update to 1.0.61a, around 63MB. I rebooted and then got finally the update to 5.0, 1GB :laugh:
I have only one problem now: the device doesn't recognize when I'm looking at the ink screen, and power button powers on the amoled... Even unlocking through swiping from bottom to top doesn't work. Option is correctly set, I tried to uncheck, reboot, wipe cache and check the option again but it not working well yet.

seems that is the same for a lot of people if not everyone..
cause of this problem i am using this app gravity screen on/off.
it halves the problem cause now i have no problem for the amoled. and for problem i mean use the pwer button instead of simply swipe.
for the e-ink panel i still have to use the power button, only way it works.

Yoga Tab 2 1050F - Need help to downgrade to KitKat

Hi everybody,
[First of all I'm french, so sorry for my bad english...]
For the past 3 hours I've tried to downgrade my tablet from Android 5 to Android 4.
I've followed the instructions, but I'm "stuck" while I'm flashing with Flash Tool lite (v. 5.4.2.0), my tablet reboot on the desktop during the process.
What I've done so far ?
I've installed :
- PhoneFlashTool_4.4.4.1_external_win32.exe
- iSocUSB-Driver-Setup-1.2.0.exe
- IntelAndroidDrvSetup1.5.0.exe
Then, I understood that before to go back to KitKat, I needed to change the bios (return to kitkat bios). I used : restore-kitkat-bios-830-1050-v2
The procedure gone well (I think).
After that, I ran PhoneFlashTool_4.4.4.1, and I've ticked "force sparcing" to change size to 500mb, but when I've connected my tablet in USB Port (while it's on the droidboot screen), it didn't recognize my device...
So I've installed PlatformFlashToolLite_5.4.2.0_win32, instead.
With this version of the program my tablet is recognized, the flash started, but during the procedure my tablet reboot to the desktop, and after few minutes the connection is lost, and I've got an error message "flash failed".
I've tried to flash with debug usb tick, and not tick, same issue.
Few more info :
My tablet isn't rooted.
My computer is on Windows 7 64 bits Home Premium.
I don't really know what to do.
Is there something I did wrong ?

You need the kitkat rom to flash after you flash the bios
In the rom zip will be a flash.xml you select in phoneflashtool to flash the tab

Thanks for your response pug1 !
I forgot to mention in my thread that yes, I click "browse" and select flash.xml from the "target_bin" folder.
Here's what I got in Flash tool Lite's box :

Go to http://forum.xda-developers.com/thi...-lenovo-yoga-tab-2-1050f-softbricked-t3319124 post 7 and there is all the files you need

Thanks, but I already have these archives :
- restore-kitkat-bios-830-1050-v2 (restore-kitkat-bios-830-1050-v2.exe)
- yogatablet2-flash-tools-20150812 (IntelAndroidDrvSetup1.9.0, iSocUSB-Driver-Setup-1.2.0, PhoneFlashTool_4.4.4.1_external_win32)
- kitkat-YT2-1050F_S0198_150422_ROW (target_bin (file), tools file (with the programs to flash...)
Isn't it enough ?
Do you think I need one of the file you posted on the other thread ? (I ask, because I have a very bad internet connection...)

I think I found what I did wrong.
I pressed volume up & power to go to the droidboot screen, instead of volume up and down + power (fastboot).
I succeed to flash KK with the tab in fastboot :victory:
Thanks for your time !
Now I need to look into how to root the tab.

To unlock the bootloader go here http://forum.xda-developers.com/thi...yoga-2-how-to-unlock-bootloader-t3320327,post 4

Does it means that I need to unlock the boatloader to root the tab ?

Yes, unlock the bootloader then use this. http://tinyurl.com/zoapeyh for permanent TWRP
Do not forget to update to lollipop BEFORE doing the boot unlock and TWRP

OK, thanks. I hope it's "easier" than downgrade :s
Can you do me a favor ? ^^"
I read your post on the other thread, and I'm confused... I don't really know what I should type in cmd.
Can you highlight (quotation marks, or put them in bold) the commands that I need to type, please ?
Open a CMD window on your computer and type cd c:\ to get to just a c prompt.
Then type fastboot flash ESP This bit then should read the full location of the unzipped file that is patched.
An example like mine is fastboot flash ESP c:/adb/1050f-esp-patched.img , this is how I did mine and I have an unlocked bootloader and permanent TWRP

Do the upgrade to lollipop first then come back here for the rest of the instructions.
After you do the upgrade and unlock the bootloader ,have a read here. http://forum.xda-developers.com/android/development/recovery-t3322990, it might be easier,the post is by surdu_petru.

I don't want to go back to Lollipop, there are too much bugs :/ (wifi, the screen flicker on internet browsers, sometimes the tablet reboot for no reason, etc.).
I had enough of Lollipop...
Anyway, I want to stay on KK.

O.K, like you I had many problems with lollipop but after doing all this plus one or two other mods,my 1050 is very fast and stable,BUT it might not be the same for others.

Maybe one day, when I'll be motivate lol I'm "exhausted" by my 4 hours of struggle with the downgrade XD
(I suppose there are lots of manip to do for lollipop to be stable =_=), and/or when Lenovo will release a stable version of Lollipop.
How do I root from KK ?
In tried with Kingo Root, but it stucks à 10 % for maybe ~ 10 minutes.
EDIT : Can I use this method ? (though I'm not sure I understand everything... x_x)

I am not sure but I don't think you can on Kitkat

No root at all on KK ?
Edit : My tab flickers in games -_-"
I might reconsider my decision to not upgrade to Lollipop... o/
Where can I find the rom without the two last updates ? (december and march... problems appeared with these 2 patchs...)
Edit 2 : Is that one of the 2 files you uploaded ?
If so, which one do I have to DL ?
YT2-1050F_USR_S000198_1504220313_WW21_ROW (1).zip
YT2-1050F_USR_S100031_1506111400_WW52_ROW-(L).zip

S100031. You will then have 3 update to get to S100256. I have zero problems on latest update
Sent from my SM-G930F using Tapatalk

Just remember if you upgrade and then root,you will not be able to take any more updates.
But saying all that, it's easy to get back to KitKat and start all over again.

OK, thanx both of you. :good:
I'll download YT2-1050F_USR_S100031_1506111400_WW52_ROW-(L).zip.
It's the same procedure with PhoneFlashTool/FlashToolLite ? :
- Vol up & down + Power (Fastboot mode)
- connect the tablet to the computer
- In PhoneFlashTool click browse and select flash.xml from the "target_bin" folder
- start to flash ?
For the Lollipop updates (not sure I want to (re)install them), if I wait a little bit before root my device, I guess it will show via OTA, no ?

P9 Lite wont turn on

Hello everyone, have been a long time
I have a VNS-L21 (P9 Lite 2016) from Colombia, it worked fine but I started to get more and more ads over the time so I decided to unlock the bootloader and root it, and I did it, after almost a year of working just fine, the phone start to restart by itself with no reason around 1 or 2 days per month, they were not scheduled or something.
Last night the phone started to restart by itself again, but this time after it turned on completely it went off some minutes later and started to restart several times without reason, I got frustrated so I decided to uninstall root (thought it was the problem) but the problem was still there, turn on and after some minutes it went off and restart.
Then I decided to check for updates and it had a pending update so I chose to install it but after restart, it won’t come on and kept in an endless boot loop.
Can anyone help me and tell me what to do? Thanks in advance...

Hello,
I bet that along with the root you also had a custom recovery.
So if before you install the update you have re-flashed the stock recovery, simply hold vol + and power button until it restarts in e-recovery mode. At this point make a factory reset and wipe cache.
Reboot system, done.
If instead you have not reinstalled the stock recovery, download one for the system you use (android 6 or 7) and install it via fastboot. ( you can download a rom the same version you use and extract recovery with extractor.
There are two recovery.img in the rom, just take recovery, NOT recovery2 ).
Try to reboot with vol + and power until you turn it on,
then factory reset in custom recovery.
Reboot in fastboot mode, install stock recovery, reboot system and launch again the update.
Happy holidays and good luck

Hello, thanks for answer
Yes, I still have the custom recovery and I was using nougat, where can I find an stock recovery for nougat? I wasn't able to use firmware finder (didn't understand how to use it).. does the recovery in rollback package works for this? just asking...
or can someone provide an stock rom compatible with my phone?
sorry for my bad engish and my little knowledge of all this, thanks in advance.

No worries dude my english is very bad too......
So, you're in nougat L21, but what is your complete firmware ? (example L21C432B504)
Then download from official THREAD Firmware Finder for PC and unzip in a folder on your desktop.
Launch FF and go to COMMON BASE tab.
Type your complete firmware into search space and click on the search button...
Find FULL OTA MF firmware, tap on FILELIST tab, a pop up will appear...
Select the whole link of ONLY update.zip and copy/past into your browser for download...
Once downloaded, unzip to a folder on your desktop.
Download Huawei Update Extractor you find here on XDA...
Launch HUE and select UPDATE.APP you find into folder you just unzipped from upadate.zip...
Now you'll see two recovery, just select recovery.img and with mouse's* right key extract somewere on your desktop...
Done dude you have stock recovery....
Copy that .img recovery into your adb/fastboot folder (very important) and reboot in fastboot mode.
If you don't have adb/fastboot just download here from XDA..
From PC with terminal launch "fastboot flash recovery
(name.of.recovery).img" and recovery will be flashed.
Now you have stock recovery and can make stock ota update correctly.
Hope all will take right way, feel free to ask.
Good luck :fingers-crossed:

Hello again
thanks for your help, your guide is really useful
One more thing (excuse me for my little knowledge about this) I don't know what's the exact firmware for my phone, I mean I know it is VNS-L21 and should end B3xx but don't know which C... (I didn't check before the cellphone started to bootloop).
I search around the web and found some recommend the C432 one so I download the update.zip from it, would it have any problem if I flash the recovery from there?
And last thing, Can I flash recovery with P9 lite Toolkit? or just through adb? thanks in advance.

Dude at this step how can you tell you were on nougat ?
Is your device branded / unbranded one ?
I searched for Colombia firmware and L21 device don't exist, please check behind the cover,
it's wrote at the bottom. ( maybe L23 one ? )
Try to someway backup your stuff then
reboot with vol+ and power button to recovery, tap WIPE then SWIPE to factory reset.
If boot correctly see inside wich is your complete firmware.
C432 are for european area devices, teoratically should work, but will not risk...
Recovery.img can be easily be flashed with toolkit, i used it a lot of times...

Hey dude
You really know about this, I'm sure because I updated the phone to Nougat before unlock and root it, time after an update came but I ignore it (I know it was a security updated not sure which one).
Yes, I just checked my phone in the backpart and it is L23, my bad, when you say branded it means if it is related to a phone/internet company? No, it is not tied to any company, I bought it free from internet.
I really don't care about backing up, if it starts from zero or is back to previous stage is fine for me since it can turn on and use it .
Cheers!

OK, since from first time i saw this post i thinked was a hardware problem, hope no....
You have to reboot to recovery holding vol+ and power button until a recovery will appear.
Then make a factory reset as already wrote in previous post.

Hi there
Sorry for the late reply...
I managed to turn on the phone updating it through dload method (installing stock kernel and trying to update it with erecovery didn't work) without your help I wouldn't know how to to download the right firmware for my phone. Now, my phone is working "properly".
BUT my phone show a new update, when I tried to install it, it says "your device fail verification and may not work properly" and won't install the update, after that if I reboot the phone it will show your device... sign in red letters and won't turn on without choosing continue (when I was using custom kernel, it will show some letters in orange I think, but will turn on by itself without pressing continue) when I installed the firmware through dload I didn't see that message till I try to update the phone.
Thanks in advance and a very happy new year!.

Dear forgive me, even for me English it's not my main language and maybe
i did not grab everything you posted. Did you use the dload method?
So you were on EMUI 4 / android 6, but now? If I understand correctly when you turn
on the device, see the red lines and press the power button to boot into the system?
If so, unlock again the bootloader.
If you want to post some screenshots so as to simplify ...
Best regards

Hey dude,
Don't worry about replying soon or late,
we all have our personal stuff to do in our lifes...
You' ve been lucky you don't bricked your device using dload method
on your nougat/android 7 rom version.
This is allowed only to downgrade to a precedent android version (in your case android 6/Marshmallow...)
Even it says your bootloader is unlocked, it isn't, so backup your stuff and unlock it again.
Once unlocked, factory reset will start. When finished do wipe cache too...
Booting into the system will now show yellow (not red) lines and after a bit will automatically boot.
Will take some minutes... ( prepare a coffee )
Set up your phone and look forward for updates...
If all will take right direction, new update will completely lock the bootloader
and at the reboot no yellow or red lines will appears. :fingers-crossed:
Voilà, complete stock with latest firmware.
Take your coffee and enjoy :laugh:
Best regards
P.S.: Remove or obscure the screenshot with imei codes ( it's sensitive datas )

Huawei P9 lite not starting

Hi, this is my first post here so Hello everyone!
I tried to root P9 lite using below steps:
1. Get unlock code from DC-unlocker.
2. "fastboot oem unlock XXXXXXX..."
3. Phone was reset to factory default sow raw Android 7 was installed.
4. "fastboot boot twrp-3.1.1-0-eva.img" was not working (unknown or forbidden command, don't remember exact message)
5. fastboot flash recovery twrp-3.1.1-0-eva.img
6. After restart with recovery mode still Marshmallow recovery was running so I assumed flash failed.
7. I tried several time put other versions (twrp-3.0.2-0-eva and twrp-3.1.0-0-eva) but if I remember well last one was again installing twrp-3.1.1-0-eva again.
8. As that didn't helped I decided to give up and restore phone to previous state so locked bootloader using SRKToolHuawei-STABLE-V1.3-20160619
9. System restarted and restored to factory default and after running I saw message informing that password is needed to unlock mass storage (or mass memory). There was no onscreen keyboard so no possibility to type anything.
10. Restarted in recovery mode (volume up + power) and tried to recover system from Marshmallow recovery option (using WiFi) but it didn't helped.
11. During next restart I accidentally hold both volume up, down with power so phone tried probably to install system from SSD, but as there was no UPDATE.APP it just stopped at 5%. I left it as it is and after some time (around 5min) phone restarted.
12. Now after restart I see only info that "Your device is booting now...". All key combinations are causing phone restart and same message.
Please advise if there is anything what I can do now.
Will appreciate any help.

After discharging the battery phone started responding properly.
With connected USB cable, volume down and power buttons fastboot&rescue mode is working.
Phone unlocked
FRP unlocked
There is still EMUI recovery in place.
So looks like recovery partition was not replaced and bootloader was not locked again.
I can't tell what is in bootloader now.
System is cleared and can't reinstall it using Marshmallow recovery as it is probably end of maintenance.
My goal is to recover system now and I don't want to root it anymore.
How should I proceed?

Hello,
it seemed that android 7 was your latest working OS.
Can you confirm it ?
If yes what was you complete firmware ?
(example: VNS-L31C432B418/VNS-L21C185B392, etc...)
note: 'EVA' stuff is for P9 variant, not P9 lite..
that's why you f***ed your phone...

Thank you Dadditz for your reply.

It was 7 installed there for sure. And this is VNZ-L21.
Probably latest possible firmware version but can't be sure about this.
Can it be somehow checked now (guess not but not losing hope )?

I took TWRP from here: twrp.me/huawei/huaweip9.html
When I look at devices list there is not P9 lite here: twrp.me/Devices/Huawei/
Which one should I use then?
P.S. sorry for no links or pictures but as new here I can't add them for now.
EDIT: I found TWRP in SRKToolHuawei-STABLE-V1.3-20160619\recovery\p9\p9.zip\twrpp9mm.img.
Guess I should load this one.
What do you think?

I don't think firmware can be checked now...
Firmware may depend on where you live...
If you live in Europe it can be a branded one
(ex. vodafone: VNS-L21C02B345/6) or unbranded one(VNS-L21C432B505/6).
You cannot flash one of them if you have the other one.
You have to flash an OEMinfo file...
Anyhow you may try a factory reset first and let's hope it will restore the device.
Boot your phone with vol+and power till the e-recovery appear,
do the reset and report back how it went.
P.S.: P9 lite doesn't have an OFFICIAL TWRP.
Available unofficial versions can be founded searching into P9 lite XDA threads.
P.S.2 : A LITTLE SARCASM...
When you tinker with the phone you're not cooking
a plate of spaghetti with tomato sauce.
As you can see bricks are beyond the corner... and not always they can be solved...
Generally it is always better to ask before do, specially
if you don't know what you're doing ... but ... yes,
phone is yours and you can do anything you want...

I don't have such option in Huawei eRecovery, only 3 below:
Download latest version and recovery
Reboot
Shutdown
When I used first option and connected trough WiFi I got error "Getting package info failed".
I tried that several times previous days but today this phone again surprised me.
After over 24 hours with discharged battery it became even more responsive (or maybe I just treated it different today).
Today I tried Huawei eRecovery again, it tried to download latest version trough WiFi and "Getting package info failed".
After restart I saw recovery wizard.
Went trough it and I got 7.0 working.
There was no screen keyboard but after recovering backup from HiSuite keyboard is was installed.
I'm also missing some other default android applications like file explorer, mirror, voice recorder, calc.
I'm wondering if it wasn't corrupted during my activities (eg "fastboot flash recovery twrp-3.1.1-0-eva.img").

I fully agree with you.
I was searching for many instruction how to do it properly and my mistake was that I stopped fallowing them at point where I tried to installed manually TWRP.
My general conclusion is that even if system was recovered I'm not sure if everything will be ok.
I was totally surprised how my phone reacted during last days so still everything may happen.
I see also some corruption in restored system as some apps are missing.
Any advise how this could be cleaned?
Maybe I should install this system again from some trusted package like from below topic?
forum.xda-developers.com/huawei-p9lite/development/huawei-p9-lite-firmware-compilations-t3517124
What about unlocked bootloader? Should I leave it with annoying screen during phone startup or lock again?

No, this recovery isn't for nougat (android 7) version.
If you want, you can flash the one you find into HassanMirza01 TWRP thread.
Do not use 3.2.1, instead choose the 3.1.1-1 version, it's the most stable one.

Dude,
system can be fully recovered, especially now you're sure about
your latest firmware...
There was a thread with a list of stock apps, but it's been closed
because links are dead...
First thing, eliminate all safeties (fingerprints/pattern/pin)(you can add at the end of process)
You should try to reinstall your current firmware using Firmware Finder app,
download it from the big G store. Use dns/vpn method
and choose VNS-L21C22B383 FULLOTA-MF.
Also all info are inside the app. Using this method
the bootloader will be relocked.
If you wont succeed then i can tell you how to use twrp recovery
providing your stock full firmware.
Cheers

I fallowed instructions and choose first VNS-L21C22B383 FULLOTA-MF from the top (each version appear 2 times on this list).
Tried downloading trough DNS but got below message.
"Due to changes in the data exchange protocol between the Huawei server and the device, this function stopped its correct operation, but still works on older software that allows you to upgrade to one of the latest software if it has not already been done."
I tried with all FullOTA-MF versions on the list and same situation for all.
Because no other option I choose Download from last section (Other) and now I have 3 files on my phone:
update.zip
public/update_data_full_public.zip
VNS-L21_polkomtel_pl/update_full_VNS-L21_polkomtel_pl.zip
Should I install them manually?
If yes then how?
Vol+Vol-Power with those files on SD card or by TWRP?

Dude, sorry if i wrote this.
I'm pretty sure you done everything correct,
but before attempt using the TWRP it's better if you
try again using Firmware Finder this way...
1 - connect to the internet, open the app, accept the disclaimer;
2 - add your complete firmware (add model) - VNS-L21C22B383;
3 - tap on your firmware;
4 - select the one with fullota-mf;
5 - tap check firmware access;
6 - tap check availability, accept disclaimer;
7 - you should have an 'availability of firmware' popup, tap ok;
8 - go back and tap 'get update through dns';
9 - a popup 'alert' you already faced will apper, tap ok;
10 - a new popup 'select dns method' will appear, tap 'auto',
then tap run vpn service and 'accept' the new connection request popup;
11 - you should now have the running vpn service in the notification panel...;
12 - minimize Firmware Finder;
13 - open settings > tap system updater,
you should find the VNS-L21C22B383 update (check multiple times);
14 - tap on it do download and apply the update;
15 - when the download reach 5%, stop the vpn service and continue doing the process...
It's something like THIS VIDEO.
Let me know...

Hi, your directions as well as movie you provided is giving much more details than application itself.

Thank you for all your feedbacks dude.
Yep, it's clear the firmware is completely f***ed...
Tomorrow i will tell you how to use TWRP
and completely restore the device.

@JimiLincoln
You can restore the exact same rom you had on your smartphone ...
(I'm not sure, it seems it's a sort of firmware branded by vodafone)
but if I can afford, if it were you
i would install the European non-brand version (C432),
without bloatware and should also have the most updated security patch.
Is the phone single or dual sim?
Also, let me know if you want to have all stocks or
have the bootloader unlocked for future manipulations ...

You must use a twrp to rebrand your phone.
Download and flash the one i suggested you (3.1.1-1 by HassanMirza01)
When you done, come back for the files and the guide...

TWRP 3.1.1-1 For P9 Lite by HassanMirza01 installed.
I can enter it only by holding Power + Vol Up without USB connected.
When I hold Power + Vol Up with USB connected Huawei eRecovery is launched.
Is it normal?

Yes, normal, you have both
stock and custom recovery now...
Ok, i will post a list of file you have to download:
1 - HuRUpdater04.zip file (will do the job);
2 - L21C432OEMinfo.zip file (dual sim);
THE FIRMWARE:
3 - update.zip ;
4 - update_data_full_public.zip ;
5 - update_full_VNS-L21_hw_eu.zip ;
Let file 3 the same name, rename file 4 from
update_data_full_public TO update_data_public,
rename file 5 from update_full_VNS-L21_hw_eu TO update_all_hw.
Names must mandatory match the ones I wrote to you, otherwise it won't work.
This is the procedure:
Use your PC, make a folder and rename it L21C432B506.
Copy files 3-4-5 (renamed) and HuRUpdater04.zip file into that folder.
(if you want you can keep the TWRP copying the .img file into that folder too).
Copy the folder into the SD.
Copy the OEMinfo file wherever you want into the SD.
Put the SD into the device...
Reboot into recovery and format DATA
(wipe>advanced wipe>tick data and tap format in the bottom right> type 'yes').
Reboot again recovery and wipe everything except SD
(wipe>advanced wipe>tick everything except sd).
Go in main menu, tap install, find and select OEMinfo file, let it flash...
When finished go in main menu and select REBOOT then Bootloader.
Once booted, connect the phone to your PC and
unlock again the bootloader. (quickly disconnect it from PC)
Device should automatically reboot into the recovery otherwise you can do
holding vol + and power button.
Now tap install, find your L21C432B506 folder,
select (only) HuRUpdater04.zip file and let it flash...
Your device should reboot into the system correctly,
if not (if passes over 15 mins) reboot into the e-recovery and
do a factory reset + wipe cache.
Done !!

Hello Dadditz,
Everything installed and working fine
Only bothering thing is message that device was unlocked and can't be trusted.
I will keep this for now as it may be useful at some point.
Many thanks Dadditz for your great help!!!
I will probably come back to this topic when my wife will have new phone, so I will play more with this P9 lite, customize system and learn more.

Amazing polite guy,
i was very pleased to be able to help you, obviously, for what I know ...
It's not a big deal to have that 'annoying' message at boot.
Re-lock the bootloader is the only way to remove it.
You have more than one method:
Flash a previous version of your current firmware
and use Firmware Finder to update to the latest;
or wait untill a new version of your current firmware comes out
and use Firmware Finder to update to;
or use fastboot commands but it's seriously risky;
Keep it as is..
Cheers dude. :highfive:

i have a similar problem BUT i can't restart my p9 lite in recovery mode. I tried vol+ & power; vol - & power; vol +, vol - & pwer; only power. The result is always the same: "your device as been unlocked and can't be trusted....... Your device is booting now....". I try also to wait to descharge battery. After descharging, when i connect usb cable to recharge, the smartphone wake on with the same message..... Someone can help me?

Hello Dadditz,
thank you for your warm words.
I can only comment that still being polite is much easier than spending your private time on helping stranger
Also thanks for warning about locking bootloader by fastboot.
