I asked this in the newbie thread, but no one has responded, so I'm trying here as well.
I'm not good at this, so apologies if I use the wrong terminology.
The "Encrypt phone" option in the Settings menu on my phone is missing -- according to several posts here, it's disabled by default on Huawei's ROM. Someone suggested to install a third-party Android launcher app. I did so, and gained access to the hidden encrypt phone menu, however, the option (the button) is greyed out.
Would rooting the phone and installing a custom ROM enable an "encrypt phone" option? If so, which method should I use to root it? And which custom ROM should I install? Would replacing the custom Huawei EMUI ROM with the Android 5.0 Lollipop stock ROM be helpful for enabling the option, for example?
How can I tell whether the phone is possibly already encrypted?
Some forum posts mention connection the phone via USB to my computer (Windows 7) and somehow, via a terminal command, force an encryption process. Does anyone know how to do that?
Data about the phone:
Model: HUAWEI CUN-L21
Version: CUN-L21C577B115, Android 5.1, EMUI 3.1
Let me know if you need more information. I'd be so grateful for any advice!

I believe you can try this:
https://www.jethrocarr.com/2013/12/29/encrypting-disk-on-android-4/
But probably they disabled encryption on your device because it will become very slow after encryption, but on the other hand you should be able to revert it quite easily, as long as you don't mind to restore your phone to factory settings.
Please let me know if this works for you

Hello everyone!
I have a big issue with this tablet: after the new update to 7.0 I notice the system is consuming a lot of internal space and the system is not stable like it should be.
What I would like to do is to revert to the previous firmware/version or try to install any other bootloader wich now is beeing very difficult because I dont know how to do and the steps that I read to do it are very complicated.
Does anyone can help me to install the firmware on this tablet?
I have everything, the tools, the firmwares, cables, the pc... everything.
Then other thing is when I try to go to bootloader, I mean, is in chinese!!! Is not even simple and looks I cant solv my problem at all.
Please, anyone can give me a hand?
Thanks in advance for all your help and sorry about my bad english.
I will give a party with those who can help me and I will offer beers to everyone!
Thanks!
Where did you get the firmware ?
I have exactly the same problems. I managed to get the Z300M software from the ASUS website but not the P00C. Would like to roll back to software from May or before.
same EXACT problem... looks like audio_dump .wav files are the culprit but cannot delete them. used fastboot to factory reset after 7.0 update and problem came back 3 days later! can't find any older updates for the p00c online either
Somebody posted a possible solution in another thread. Can you see if it works for you?

Hey guys, see if this works:
Install Engineer Mode MTK shortcut
Turn on developer options
Start Engineer Mode. Go to Hardware Testing -> Audio -> Audio Logger
Uncheck any boxes that are checked
Profit (and maybe reboot)
All in all, I don't understand why some tablets have the logging enabled and other don't, if this is indeed the issue. I've never seen it enabled, even after a factory reset.
If you have the audio logging issue on either the Z380M or the Z300M, please post:
Your firmware SKU
Your region code given by the property ro.config.versatility (may need a terminal app to read that via getprop)
The firmware version you were on when you reset your tablet

Hello, short Story before. I got a full Hand of non working mobile phones because being full of a hell of viruses.
5pcs. younger ones.
2 Huaweis and 3 Samsungs.
Well so far 4 PCs. are saved.
Getting into the phone wasn´t possible anymore. Data not important so I resettet over the Buttons to original Status. -> Worked fine.
But one Piece which is a Huawei P9 Lite guess it is a single sim? was the button method not possible cause it wanted a Software update and Installation of WLAN failed (EMUI)
Getting into the phone for any informations was also not possible because of all the viruses and not working right ahead anymore.
Well ok -> will use High Suite for stock Firmware -> this mobile phone is not supported and also couldn´t activate MTP as I am not in the phone. So far.
Next Idea -> ok. will take the C900B300 and go back to Marshmallow. From original HUAWEI site.
Took the European Version in German. Did it over EMUI (hold 3 Buttons) and worked so far but when I turned on I was stucking on the WIFI+. Even pressing the button -> further nothing anymore. So I thought -> maybe another stockfirmware useful.
Again C900B300 and then I think I did the big mistake. Took out the sdcard during it was rebooting (HUAWEI was already visible) and now it is big crap. Stucks at HUAWEI. Turning off not possible. This EMUI is not possible anymore. Just with a trick I am able to get into fastboot. Yeah. But what then? Reading TRWP which I know from Samsungs but putting it on with ODIN. ODIN doesn´t work with Huawei. Do I Need TRWP to get it back to normal Firmware? Mobile phone was never customized or anyhting else. just normal stock was on it and is the wish to get a clean back. Resetting to factory was not possible anymore.
So my questions, even I know it is my fault. Any rescue possible?
What could be the best stock Firmware. I Guess it is a single sim from Austria unlocked and unbranded. Would also take Nougat again. Just wanted to get it back to normal working and now I guess I have a big letter holder. Model from the backside is VNS-L31. More I don´t have.
Thanks a lot for any help for my being an idiot. Samsungs are much more easier than HUAWEIs.
Blimey mate,
This really just boil down to what partitions were damaged in your case- Most likely your system and data,
however since you are still Technically running unmodified emui you could manage to sort of salvage it.
The logic is this:
Most custom roms for the p9 lite build on top of emui (patching the system image) rather than replacing it (like the way samsung smartphones do)- so you could flash the rom, it would wipe your phone clean of viruses in the process and then proceed to do a hard restore back to emui.
1.) get your phone into fastboot and flash this twrp http://www.meticulus.co.vu/p/forum.html#nabble-td27
2.) Then flash this rom : http://www.meticulus.co.vu/p/ressurection-remix-for-hi6250-devices.html MAKE SURE YOU FOLLOW THE INSTRUCTIONS ON THIS SITE VERY CAREFULLY
3.)Follow this guide to do a hard restore https://forum.xda-developers.com/huawei-p9lite/how-to/tips-revert-custom-rom-to-official-t3668413
good luck!!! if you have any questions hit me up!
Hi
Hi Exiatron00,
thanks a lot for your maybe solution way. Will do it this evening after work and come back.
Hopefully it works cause as mentioned in other threads -> don´t think that the original owner opened the Debugging so that I can work over a tool. FRP locked is in fastboot. This was already mentioned in other posts which I have read here in the forums.
Thanks for your step by step explanation. Will do it. Hopefully it works. I am really pissed of my own that i was unpatient with the sdcard. That´s a mistake which shouldn´t happen. Anyway it did. So i will try to do everything to get back working again. I am from IT so I am not such a DAU but newbie with HUAWEIs. Most are Samsungs.
Will give Feedback.

If u need to transfer files , just boot into twrp (it has built in mtp support) , then transfer the file from ur PC to phone via a micro us b cable.
If you are unable to fix the phone I do actually have a FULL twrp backup of my phone (EMUI 5- single sim Europe VNS- L31 C432B370) hit me up if u want it.
Hi,
well adb for flashing not working as device not found. Hi Suite installed. Guess that the USB Debugging is not enabled. hrmpf.
There is a similar thread of somebody with no enabled USB Debugging.
https://forum.xda-developers.com/nexus-4/help/fastboot-recovery-remotely-enable-usb-t2177440
He writes an solution how to enable in fast boot mode with using N4 toolkit.
Search for a p9 lite toolkit and found this
https://forum.xda-developers.com/hu...nt/europe-vns-l31-toolkit-bootloader-t3432873
may could work?
Big **** -> as Long as USB Debugging is not enabled as Long I am not able to Flash TWRP over adb.
If I connect to PC Hi Suite opens automatically. So driver should be fine as pc recognize the phone.
hm?
Got it working somehow

Hi Exiatron00,
got it working somehow!!!!
Bought a 3 day licence for DC Phoenix where you are able to put Firmware even in fastboot with FRB lock and no USB Debugging on.
So I got the IMEI and Fitting Version which is a L11.
Downloaded it original from Huawei as I still want a original stock Rom not customized which was
HUAWEI P9 Lite Firmware (VNS-L11, Android 6.0, EMUI 4.1, C432B161, WEU) only wokring one.
BUT the big Problem is that the apk Android System Web View is missing in the ROM. A known Problem by HUAWEI. Yeah now I am stucking in the Setup wizard like this guy who mentioned also the solution whell the reason of this Problem.
https://forum.xda-developers.com/hu...stuck-initial-setup-upgrade-to-t3498097/page2
So my question now. How do I get the apk on the phone still no USB Debugging? Does anyone have this Version original incl. this apk? Maybe an img. from a running working System?
Only way I am able to put the Firmware on is DC-Phoenix. It is valid still two days. Maybe someone can help me? Please?
So an Image of VNS-L11, Android 6.0, EMUI 4.1, C432B161, WEU incl. Android System Web View, so that I can go ahead and use the phone again please?
Thanks a lot.
Kind Regards.
Currently my device doesn't support USB debugging, file transfer etc. for some weird reason. Hence, decided to reset it to factory settings and then root it. It is updated to the latest version (Nougat). Kindly help me by laying out detailed steps to root my phone and install custom roms (preferable OREO) so IMEI and other functionalities won't be lost. Also, kindly guide me how to take proper precaution like backing up stock rom and other settings, in case something goes wrong and I need to unbrick the device. TIA
Sadly, still can not access any menu from notification area, and hence no USB debugging
I apologize if some questions have been answered, please post the link.
Thanks!
1. Which is the best way to backup Non-rooted devices? LG Backup doesn't restore all data apps.
2. And best way to disable apps (aka Debloater- didn't worked).
https://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294
3. I have problems with Wi-Fi and Tethering. Wi-Fi appears "Connection not allowed" and can not connect, or if it connects does not make traffic. And using Tethering I can't connect from other devices. May be software or hardware related nature?
4. Anti rollback should be 0 (Zero) for downgrading? If so, what is the latest version where anti rollback is zero for both Android 7 and 8 for LG V20 990DS SEA?
5. As far as updating from Android 7 to 8 Non-root OTA can I root later by downgrading to 7 and use this method?
https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296/
6. I have used LGUP and selected all partitions from DUMP. Is it enough if something goes wrong, do I have everything I need? It must have specific extension?
7. If I install TWRP is it possible to go back to stock recovery (how)?
Seriously, no recommendation?
Hi.
First of all, I want to let you know I'm just new to this page, so I'm so sorry if I make any mistakes within creating the post.
As you've read in the title, I can't fix the OS of this phone. I bought it used, and apparently it didn't have any OS (I thought it was because there was a flashing attempt, which went wrong). One day, I just looked for Android 9 and I installed it. The phone started working, and so I started using it. There were some problems with the phone though. First of all, at random moments, it started lagging and just re-starting. The other problem I had was the bootloader message, saying that I didn't have an official OS.
Today, I tried to uninstall all of /system. I read a lot of information, I watched a lot of videos and I started doing so. Basically, what I wanted to do is delete all in /system so I could install a clean ROM from my computer. Problem is, I have "flashing_locked" flag. I also downgraded it to Android 8, and I think it made it worse. Now, I don't even have internet connection (or what is called /persist), which also means I'm stuck in the setup screen. There's no way I have now to enter developer mode, nor activating usb debugging. Just wondering, is there any tips I could get from you guys to fix all this problem?
Thanks a lot.
Edit: I also think there's some "residual" data from those flashing attempts, Android 8 and also Android 9. I'm not sure if that has something to do.
Edit 2: I also requested a Unique Key from the Motorola official page, which didn't lead me to anywhere. Although I used "fastboot oem unlock <key>", it didn't work to me.

I'm wondering how you managed to downgrade the device from Android 9 to 8 with a locked bootloader?? that's very strange... To fix the known issue of broken wifi/mobile connection (as a result of the downgrade) it's recommended to revert back to Android 9.
So, you did the downgrade from 9 to 8. But now you can't finish the setup wizard to activate OEM unlocking? Please tell me, at which point it has been deactivated?? It doesn't make any sense...
Try the Lenovo Motorola Smart Assistant tool. It'll fix the issue.

I think not. Flashing a firmware means copying image files to a specific partition. Each image file got its own partition table. There will be no data left.
