I got a notification for system update. When I rebooted, my tablet started up in TWRP. The update finished (I don't Know if it was successful or not). After I rebooted into system, my usual PIN is not working, do I can't get access. I'm away from home and away from my PC for a couple of weeks, so I'm limited in what I can do.
Does anybody know how to get a PIN to work? Looks like TWRP has been replaced with regular recovery on partition 1, but I have TWRP on partition 2 also. Is there a way to get into TWRP on partition 2 without a desktop PC?
I have the same problem, after the system update yesterday my old pin does not work anymore. What could I do?
So, before you updated, was your tablet rooted? Did the update use TWRP or the stock recovery? Did you have a pin set before the update?
before the update I use PIN and fingerprint reader, device was not rooted.
The update was offered by the device and ran normally.
Now my PIN does not work anymore. I do not have an "ok" button
when entering the PIN and I do not remember if there was one before?
My pin was reset after I updated, but I thought it was because I had replaced the stock recovery with TWRP. I've heard that there's a bug in TWRP that can mess up your pin. Now it looks like the pin problem is happening with stock updates, too. I'm surprised that other people haven't reported it.
If you had TWRP installed and you were able to boot into it, there's a way that you can use the TWRP file manager to delete the pin lock files. In your case, you will probably have to do what I ended up doing. I copied into Huawei eRecover and reset the tablet. That means it was wiped and I had to restore my apps and settings. You could try to get in touch with Huawei support first and see if they have a solution, since it appears that a stock update caused the problem. Please post back again if you find a solution.

Background details:
- I had a good working Galaxy S4 running Stock 4.4.4, with Root/Safestrap/TWRP (Phone was not encrypted)
- I rebooted into Safestrap and did a full TWRP backup to my ext SD card [fat32]
- I tried to install CM-12 zip via Recovery Mode, but I think I missed a step and something didn't work out. So I,
- Rebooted back into Safestrap and selected "Restore" from the options. Restore ran for a while, rebooted and restarted successfully.
Now here's the strange part. Restore appears to have completed successfully because I can now see my original wall paper and the unlock screen. BUT my 4-digit numeric PIN doesn't work to unlock the screen. And it looks like wifi and cell phone service aren't connecting. So I"m stuck. I've tried the known-good PIN multiple times, but same results.
I guess I could Odin back to stock and go through the process of installing all my app's and setting them up, but I really don't want to do that.
Any idea why my PIN would not work or would have changed?
Which Version of TWRp do you use?
I remember that it's a known problem with some Version and the only way to prevent it, is to reset the PIN before backuping.
But you could try to delete the /data/sytem/locksettings.db to reset your PIN
If that not works try to delete the .key files in /system/data and create a new PIN after rebooting
Encrypted 6P with Nougat here. A week after flashing the OTA, unlocking the phone with the initial pin code worked fine, but I started having problems unlocking the phone again by swiping. It just wouldn't be swiped out of the way. It became more and more difficult . Had to reboot all the time in order to get access to the phone, through the pin code unlock.
Initially reflashing the OTA and removing 'trusted locations' for smart unlock seemed to do the trick. 10 hours later the phone went into the same problematic lock screen mode again. This time without any trusted locations.
Installed an alternative lock screen to see if that would work. This required disabling the default lock screen...
After the next boot up, the phone says that the password was correct, but 'decryption was unsuccessful" and the data is corrupt. Will need to perform a factory reset.
Does anyone know a way to avoid resetting the phone? Flashing back to the latest Marshmallow did not help.
Thanks so much.
OK, for anyone else finding themselves in this situation: make sure you get your backups off the phone before it's too late.
After a factory reset to Nougat everything is fine, but all my stuff is gone.
Hi all. had an issue while trying to load up LinageOS last night. Was having trouble with keeping root. Seem to have solved that by using Magisk 11.6 and the SUaddon rather than any superuser version.
Anyhow as part of this i went back to a TWRP backup of which i had 3 different versions (stock and lineage) available being a bit ocd with backups. They all flashed ok, but for ALL of them, when the phone booted it kept telling me had wrong pattern when i tried to unlock. Not good. Thought only way back was to factory reset and do all the app loading and setup again.
After a bit of searching found this thread and this post.
https://forum.xda-developers.com/showpost.php?p=69189392&postcount=65
Worked a treat.
The other methods didn't and i suspect are obsolete.
Anyow, posted for info if anyone else runs into this problem. Success dependent on having working TWRP and being able to boot to that as you need to use the File Manager capability in TWRP.
Seeyahs!
Same thing happened to me last week, when I tried lineage, found the answer on HTC forum,.
So avoid that from happening , before you make a backup, unlock all securities( pin, password, fingerprint) then make a backup, next time you restore your backup, it will boot without any issues.
ta for that. will try.
I i had to reflash the firmware the correct one TB-X104F_S000024_180930_ROW_DCC. Anyway it wasn't booting at all before i flashed. Now it boots, shows the logo etc and constantly says Encryption unsuccessful!, so i reset it and factory reset it but nothing changes.
I have no idea where else to go, bootloader is locked and all i can do is flash the firmware. Would there be a way to remove this from the files within the firmware?. It seems like android is there in the background but i can't get away from that encryption unsuccessful screen!
Sorry if none of this makes sense.
Yo. I got the same tablet bro. Been trying to figure out a custom recovery for her. A stock ROM would be great to have and I haven't been able to find one anywhere. Might I inquire as to where you found yours? It would be a huge relief to know I can fix it if I break it lol.
encryption
If you download the Lenovo MOTO smart assistant from Lenovo support it has a resque option. I also used that to root my tb-x104f. It downloads the original everything and if you take the boot image from the file it downloads and replace it in one that has been modified from magisk it will rescue it and you will have root also thatd what I did with mine
same problem here, reflashed with stock rom. and not resloved

Did you fix this issue?
I am having the same problem.
Thanks
Same problem here (my error reads "Decryption unsuccesful", but I think it's the same as yours).
After a few tries, I believe that it is a problem with the internet connection. After the factory reset, if I skip the wifi connection step, it starts normally. And it is completely usable. I can load pdf documents or apks by the usb from a computer and it runs correctly. But whenever I try to set the wifi connection, it updates something and it causes the tablet that the next time I turn it off, I find the error on the picture when turning on. It asks for a password and no matter which password you enter, then it delivers this message.
In resume, right now it is a completely functional tablet if you NEVER connect it to the internet and load anything you need via usb or bluetooth.
I tried to reset it with Lenovo Smart Assistant, but the result is the same.
I am looking for custom roms to try if it's something about the stock rom, but I haven't found any. Can anyone reccomend me a rom for Lenovo E10 X104F 2GB?
Solution: (Worked for me)
Format Data as F2FS in TWRP. (Advanced Wipe)
Then reboot and wait.
I had attempted to install Evolution X, and after installing Magisk I had an issue with WiFi not working.
After reading another thread where a user had success installing PQ1A.190105.090 from fastboot, I decided to do the same myself.
After installing PQ1A.190105.090 it does not go through the setup process, and instead asks for PIN. Entering the PIN causes the phone to crash right back to the lockscreen.
I even tried wiping Data from TWRP (Which also asks for PIN and says it is incorrect)
I think I managed to mess up my phone, can someone be of assistance? Thanks!

No expert here but I am pretty sure I read on here of others having had issues and thus advise to disable PIN lock on the phone before attempting. Might want to try a search on here for that and it should point you to how to fix it.
Hopefully others that have rooted already will chime in for you. I am still stock 10 due to the whole A-B slot thing that has me scared.
