Vns l21-c432b170 ??? - Huawei P9 Lite Questions & Answers

In I should say desperate hope and waiting for official Nougat, and by carefully following this forum , I have found that we have new update, of course it is still MM, but I have decide to give it a try. So I downloaded it, unzipped it in dload folder on my SD card, and installed it. It all went like charm. But, When I have done factory reset. I have found that my poor P9lite become stuck in initial setup. For six damn hours I have struggled to revive my device. And, I have finally done it. Reflashed old B161, done factory reset, and my phone is now working.
So there goes my question: As far I know, the reason for stuck is that in B170 there is no android web-view.? Or I am wrong.
Now I will not flash any other official upgrade, unless it is proven correct and full.

It's working very well. I have not any problem (I flashed full version without wipe)

I have flashed B170, factory reset phone and it's working without hickups.
And android web view:

I did not say that it is not working, but I could not pass wifi setup. It has repeatedly bringing back to the wifi plus page. When I tap disable, it opens account screen just for second and then brings me back to wifi+ , same when tap on enable.
Similar hickups were mentioned in this forum, but for L31 and B161 firmware. But I did not had those hickups on my L21. Just to say, I have done factory reset on B161 today, just after I give up all hope, and B161 worked as it should. On the other case, B171 did not.

lag, freeze, restart after 6.0.1

hey guys, today i bought a used NOTE 4 for my mother, and when i checked the version it was 6.0.1...so i wiped everything and restarted the phone to get the best performance....but the phone lags and freezes a lot, especially in the camera, and it keep restarting all the time....what should i do? should i try to flash another FW through ODIN?
You mean you used the Factory reset option? That's not a full wipe, just resetting stuffs. And yes, you know the answer, wipe everything from a custom recovery, then flash stock MM ROM (always latest) via Odin. Earlier versions did have a reboot problem though, and lags here and there, but that's expected, but the last release, PE1, has got rid of all those problems, its a very good release already, and I am sure upcoming releases will only make it better. There are no major bugs at all, I don't even find any minor bugs except the need for a separate app to clear default apps selection.
Best of luck.

the phone is stock, it has the stock recovery, and i have the PE1 version, the exact name is "MMB29M.N910FXXU1DPE1"...and still got a lot of lag, freeze and rebooting.....is there another version?
EDIT: ok, so i flashed another MM through odin ( first time it gave me a fail) and then done a factory reset, now it's so much better, maybe not as smooth as my S6 but really fast and smooth enough...thanks for the help
EDIT: today the phone started to shutdown completly....not reboot....and you need to press the power button 10 seconds to reboot it or turn it on...is there any advice?
Guys . Ib tead the whole thread over last few day had wake lovk runnimg last couple weeks. Lastnight used kies for reset and it crashed half way.
I then used odin 307 and went back to stock 501
It booted strarted to restore from google apps ect .
I allowed the 1st 601 update
All apps running aok no crashing freezing no wakelock .. its asking for another 601 update. Im gonna hold back
Hope this helps .. will post agian in gew days with any updates
Good luck !!
Just download and install Wake Lock from Google Play Store. I had the same problem and more. Once I installed Wake Lock (on a fresh install from Android 5 up to all the 6.0..1 builds) phone doesn't shut off or freeze. Most importantly no more Boot Loops..

[SOLVED] NRD90M test-keys

I just got an OTA update and from VNS-L21C432B160 to B370 which was around 1.94GB but I wanted to make a clean install so I removed superSu from the app did a factory reset first then went back to update where it now showed something around 1.24GB. So I went through with the update everything seemed fine until I couldn't find the Dual-Sim manager. I went to About Phone section and noticed that my build number was NRD90M test-keys. How can I get a clean C432B370 from this point on?
Same thing hapened to me.
After update, strange build, but no BT functionality and no file explorer. Contacted Support, told to do Factory reset. Now gets interesting.
Factory reset failed after 6%, now im stuck with device with no keyboard?!? Basicaly, i can just recieve call's.
And to top it up, PC dont see device, cant upload anything on SD card to try 3 button update etc.
Before I have downgraded from N to MM because of camera problem, to do so, I had flashed Dual Sim OEM per instructions, I can think that that is causing some problems.

Same thing happens to me with factory reset, fails at 6% boots back like it performed a factory reset. I'm greeted with the first time welcome screen. No keyboard no file explorer no updater. I managed to dictate apkmirror on chrome and downloaded gboard and esfile manager. And I lost my SD card to perform a 3 button method. Can I do the 3 button without an sdcard? Maybe using the internal storage?
EDIT: Well I did the 3 button method and failed at verification. Anyone can help me how do I get out of this?
EDIT 2: Back to MM with this tut https://forum.xda-developers.com/huawei-p9lite/how-to/tutorial-rollback-n-to-mm-c432-devices-t3563955 and downloading B370 thorugh the official updater again
EDIT 3: Everything went smoothly and after, I even got B380 OTA.
EDIT 3.5: Did a factory reset after B380 and everything is working.

To start android, enter your PIN

i successfully downgraded my A2017G to Oreo b02 from b03 about a week ago. I had to do a factory reset, then set it up with my Google account and after that it allowed to install b02.
After that I've only installed a few basic apps for my bank and so on while waiting for b04 to show up through OTA.
Anyway, fast forward to today. I haven't had any issues with it. But all of a sudden when coming back from working in another town its rebooted and ask me to enter PIN to start Android. After that when it's done rebooting I got some weird double spacing between rows of icons.
So, I reboot again and once more i have to enter pin to start Android.. But it looks better when finished. However, this Enter PIN to start Android feels a bit annoying. Apparently it's because Android thinks my phone is behaving strange. Is there a way to find out what it thinks is strange and stop it?
It may be a security requirement for your banking app. It's secure boot.
This is part of the options with lock screen method. Maybe try setting the phone back to a swipe unlock and restart, see if it stops the problem. If so, set up you preferred lock arrangement again.
Thanks. Sounds reasonable although I've been running these apps on this phone since I bought it back in 2016(maybe it's time for a new phone) with various Android versions and never had this before. The phone has also been running for about a week with the same ROM and app version before this happened.
I'd backup data and reset it. See if it runs better, but you could try going to stock recovery and clear the cache first, just in case that helps.
There may be some junk from flashing it.
Seems like a factory reset did the trick. It's been running smoothly for some time nu despite installing the same apps again. I even got the b04 upgrade through OTA. Thanks!
Cool, so you're happy with the A7 again?
I regressed mine from B03 to B02 and did forced update to B04 from stock recovery. Had a few hiccups but sorted them and it works ok now. Do want to reset it when practical though. I use it for work so not in a huge hurry, setup is a big deal........

Sort of happy I guess. There are still a few things like it not automatically mounting my sdcard after reboot and I'm a little thoughtful about how many more updates it will receive. But it works rather well now and I haven't found a suitable replacement yet so I'm happy with it for the moment.

[FIG-LX1] Bootloop problem, downgraded/updated stock

Hey there, a friend of mine works at a place where he is in charge of the correct disposal of broken electronics. So he usually gives me phones. This one had the screen cracked. So I replaced it and I am now trying to get it to work, as I found it stuck in a bootloop.... It reboots itself several times until it takes me to a emui menu where I can turn it off, wipe it, etc. It's the first time I repair a huawei so I don't have much of an idea what to do.
edit: At first I was trying to flash wrong stuff through the microsd card so It got stuck at 5% or give me errors, now I succesfully flashed emui 8 / 9 but anyways it's bootlooped. I noticed a safe mode option on emui 9 recovery, but that does nothing... Factory reset / cache wipe do nothing. When putting the phone to fastboot mode it shows "Phone locked" and "FRP Locked". I would just like to get it to boot but it keeps rebooting and going into erecovery.
If anyone knows anything that could help me fix it I would highly appreciate it.
Thanks
One of the tutorials about downgrading emphasizes that the micro SD must be formatted in ExFat. And you can also try to use HiSuite to restore/fix the system.

Hi, thanks, but I forgot to mention that I also tried with exfat/ntfs format and it doesn't work either. Also, HiSuite says this phone is not compatible with system restore :\ any other ideas? Maybe I'm trying to flash the wrong file , but I tried about 7 files already and none of them work ....
edit: I searched for the downgrading post you mentioned just in case I could find something usefull and I tried the same file mentioned there and IT WORKED! damn, finally... thank you very much!
edit: Well, it does complete the updating process but then it's in a bootloop again. The post there says it's supposed to happen so a factory reset is required. I do that but anyways it doesn't help... but well, I guess I'm getting somewhere now... I installed the latest firmware version 9.0.0.3 and I know it installed correctly because the recovery is now white, so It must mean it updated. But anyways, still bootlooped... Safe mode does nothing, factory reset does nothing either...
Do you know what type of p smart it is like FIG-LX1 etc and which varient ?

Screen Lock security issue G975F Q Beta 2

Hi, Today I was using my phone and in mid day I realised my phone is not accepting my pin code but finger print is working fine.
I tried many time but pin didnt work and I used my pin code unlock few hours ago. Long story short I have reset my phone from recovery and setup my phone again.
BUT when I try to put a pin lock or password or any other security, my phone gives me error that is "Screen lock was already changed. Try again with the new screen lock." Screenshot attached
Any solution to this?
My phone is G975F on Android Q beta 2 DBT (VAU).
I have done factory reset , installed new firmware but it is not working.

Was this right after installing the beta 2? When you installed Beta 1 did you leave the system as it was or did you factory reset it? if so can you quantify how many times you unlocked your phone before went south? Was you stuck after rebooting from realizing your pin is not working? Meaning, after the issue and you restarted the phone was you able to enter your pin and proceed, then afterward it stopped?
[edit] The reason why I ask about the factory reset is in one of the other Beta threads people was having a lot of issues and after a factory reset it became near flawless. As of right now I''m monitoring my phone to see if this will happen to me, however after Beta 1 I did a factory reset, so I'm not sure it's a symptom of lingering files. I usally after applying an update to a beta ROM, I factory reset and out of all the times I did it, Android Q was the most buggy and was the only Beta i reverted, but the phone was a Pxiel..

I intalled beta 2. Everything was working fine. But when I restarted my phone, it stopped accepting my 4 digit pin. Then i hard reset the phone and factory reset. But after that it not accepting any new Pin or Pattern to register.

I did a clean install fresh firmware for beta 1, clear cache for beta 2.
I am not sure how many unlocks but i took few days after beta 2. My phone was waorking fine in morning as I unlock my phone in car using pin. But in after noon when I used the pin it showed me wrong pin. Every thing related to security wont work. Cant register finger print or face. But if you do same in secure folder everything will work fine.
Okay if it happens to me I will try to track down how it happened.
You did something and screwed up. A lot of people are using beta 2 already and have not encountered this issue, myself in it. I have done a lot of restarts and I have changed my pin successfully.

What about other people who are affected by it? Read comments in Android 10 beta thread on page after 135. You will find people reporting this issue.
I didnt do anything with my phone just updating with beta.
I'm another that's been affected, had to do a factory reset via bootloader.
Currently stuck on Beta 2, Smart switch won't downgrade.
No security options available and an extremely buggy phone.
A new update has been pushed out. I just received it on my phone. Will be performing a factory reset once the update is installed and will setup the phone from scratch.

Update me if it has fixed the security issue.
i installed *emergency update* , no wipe,no reset ,things go back to normal
Everything is cool as the phone has not been blocked. Otherwise there is no way to upload the update.
I wonder why they can't release the patch to upload it via ODIN, that would solve the problem.
Wait what !?!?, the same thing happened to me
Even worse - i rolled back to P, where i was able to add a pin but it would always forget it. I ended up going to a samsung center where they changed the board (in warranty), they said my unique device key was corrupted - likely due to internal storage error
So it is a beta problem then
Please provide feedback in the samsung members app. Those that cant, send feedback in the official thread at samsung forums.
Beta 2 is Terrible, having all kinds of Problems with it. Beta 1 was Much Better. Hope another Update comes out soon or will just go back to PIE. G975U S10+
I do have the same problem on my Zenfone 6z. After I relocked my bootloader I couldn't set up a pin. Asus still haven't rolled out an update.
