Help!! - Unable to access my P20- Invalid PIN - Huawei P20 Pro Questions & Answers

Hi Guys,
I have an issue accessing my P20 pro, that I PRAY someone can help me with!
So, the story goes as such. I recently updated my P20 using Hurupdate, and as part of the process i disabled Screen lock in Developer options (i didnt delete the actual PINs, fingerprints etc from the phone) in order that i can get access to the data partition in decrypted format in TWRP and update the phone.
Upgrade appeared to go fine and phone worked no problems...until I tried to re-enable and re-implement fingerprint unlock. It asked me to set up a 6 digit PIN first, which i tried, but it seemed to go around in circles. Eventually it took a PIN, and then BOOM! I was unable to use that PIN to access the phone.
I've tried the old school method of deleting the locksettings.db file from /data/system (didnt seem to be any .key files for some odd reason), and now i dont get prompted for a pin, but i get a blank desktop. This is clearly because the data partition is still encrypted and the phone cannot access the data to start up my desktop etc.
My question, is there a way to remove the PINs/Fingerprints and security setting via TWRP on the P20, in order that the data partition mounts in decrypted format?
This is really important guys, so any help would be amazing. I have photos on the phone of a family member that recently passed away very suddenly, and I would be devastated if i couldnt get them back.
Cheers all.

Have you deleted ALL locksettings files and all files with .key ending? (Oh there were no key files)
password.key
pattern.key
locksettings.db
locksettings.db-shm
locksettings.db-wal
Something like that.

Yeah they are all gone. When i reboot the phone into the OS, i just get a blank desktop and no launcher.

Hey man,
I have got a similar situation. Did you manage to solve the issue?

You may have to go into the boot-loader and do a factory reset

Need help, device freeze after entering pin code.

I was about to install a theme and the phone rang, and then locked up.
Restarted the phone, entered security code, then pin, and after pressing enter the phone freezes. Need help.
Do a hard reset! I has worked for me.
Thanks. have done that now.
Lost allot of numbers etc. Is it just to delete every program in the hdd memory that was installed?
They dont work anymore so...
Yes it will delete all programmes that has been installed on the internal memory, not the programmes that has been installed on the 4gig.
Make a backup of all your numbers it will save a lot of work for you next time!

Out of curiosity which ROM were you using?
yea, know, have most numbers backed up, but not for the last months.
But the progs on the 4gig isnt listed in progs folder.
Is it just to delete all progs on progs folder on 4 gig? just delete the folders?
The register is cleaned so you will need to put the programmes back in the menu by copy and paste (the short link) or you can reinstall the programme

Cracked Screen, How to blind copy data to replacement??

I just got my captivate 1 month ago (first android). I rooted the phone and installed Cognition 2.3b6 right when i got it. I have never backed up the phone.
2 days ago the phone dropped from about 18 inches onto the bathroom floor. Cracking the interior of the screen. Origintally i could see the top half, the touchscreen hardly works. Now i can only see a faint blue color when i boot hte phone. It still works, i get alarms and feel it vibrate.
I understand that I might be able to do a nandroid backup (is it possible to do it blind?), but is that the correct thing to do? Will that change the deviceID of my replacement phone from AT&T (insurance replacement).
I would like to get the data backed up and transferred over asap so i can pack the old phone up and ship it off before the holidays.
Thank you guys!
adb pull /sdcard
Some one else might be able to help you with the specifics, but pull the /sdcard data from your phone.
From a phone
what?
I figured i need to probably copy it to the sd card. But from what i understand, some applications rely on DeviceID's and not the actual phone. Ergo, if you do a complete nandroid backup it will also copy over the DeviceID (from what i understand, correct me if i'm wrong).
Or is that something different than what you are suggesting?
Your data is stored in /sdcard. The external sdcard is /sdcard/external_sd for froyo, cant remember file path for 2.1. What else could you be wanting to transfer to the new phone?

I've never done it before, I want to be able to transfer all data (ie, installed apps, cached notebooks for evernote, preferences, etc) to the other phone.
I have never done this before on an android phone and don't know the best way to tackle this using a cracked screen (can't even unlock the phone)
I think I can manage to do a nandroid backup ( http://www.youtube.com/watch?v=sEqbjUb4WxM ) but i'm concerned about the device id

There are 2 way i can think of.
1- Like mentionned in prior post do a adb pull /sdcard
2- Boot into recovery and try to a backup from there blindly (following online pictures/video of the different menus and pressing the buttons accordingly).
I don't see the big deal about your deviceid. Many users have had a auto generated id with roms. It will be ported with the nandroid. Not sure just how wide spread the use of deviceid is used in apps.
Thanks I was really confused about the whole DeviceID thing. Figured it was best to play it safe.
I'll give it a try, i'm sure i can manage to do a nandroid backup on my phone
I'll keep you posted
There are ways of getting your device id back. First of all theres a market app that can backup the device id on your new phone and restore it back after you restore the backup http://www.appbrain.com/app/android-id-changer/adaptive.cogid Or you could search around the forums and/or google for ways of changind and backing up your device id, there are multiple ways of doing it. And don't forget about backing up your sdcard, like boborone said, do an adb pull /sdcard from the clockworkmod screen (adb works from recovery in case you didn't know).
Hell man, you can adb pull the whole phone if you want.

Can you send the link to where i can find out how to do and adp full pull from the pc? The only instructions i'm seeing are for the android sdk (bit confused)
the sdk is downloaded to your pc, and then you run that command from a terminal/command prompt with the phone connected.

Do i need to have left the phone in USB debugging mode? I believe 3 days before the accident, i turned off USB debugging on purpose (for file transfers)
Check out my Screencast video...It may help you here.

I believe you can use adb from recovery screen.

Thanks, the screencast helped, but i honestly think that 2 days before i did this, I turned off usb debugging (so i could use my phone as a hard drive)
I think that is why whenever i plug in my phone, it vibrates really hard and droid explorer doesn't find any devices. Suggestions?

[FIXED] Password glitched, need help

Hi there guys.
First I just want to explain that I am not new to Android in general, but have almost no knowledge of Samsung models specifically. It seems they work much differently than my xperia, and so I am lost.
Anyway,
My niece has a Rogers captivate, stock 2.3.3 that was password protected. She changed the password to something new, and the phone glitched and won't accept the pass now.
Her password was very simple, only one word, so we know it was the phone and not her mistake. We tried different spellings, even typos just in case. Didn't work.
Basically, now she's locked out. I read on multiple sites the phone would ask for her email (we know those details ofc), but instead it just does a 30 second timer, then allows the pass to be put in again..
I'm trying to find out how to disable the password without wiping the phone. She has a lot of games, and some apps that are no longer in the market. Is it possible to install recovery and use an update zip to replace the file where that setting is stored? Or alternately, would we be able to access adb from recovery and do it that way?
The bottom line is that we need this:
A way that allows her to keep the apps and personal data while removing the password.
Thanks in advance.
UPDATE: I couldn't find info on adb password removal (I saw for pattern unlock but not password), or loading adb through recovery, so instead I did this:
-Flashed a cwm kernel with Odin
-mounted storage through cwm
-backed up everything from sd to my computer
-installed cm7
She is now enjoying cyanogen although her contacts hadn't been set to sync for some reason, so they're all gone. But hey, at least the phone is usable again.

Dual App (whatsapp) no Write permissions

So i made a dual app with whatsapp and everything seem to be working fine until i noticed i couldnt download or send any media files.
Ive been reading and searching for hours but i cant seem to find the solution.
In the Dual Apps partition, i only have 1 very weirdly/random named folder.
I cant delete or add anything to the partition... if i try to delete i get ask for permitions, when i grant them it ask for them again... (i checked it already has them)
So im almost sure its a permissions issue, but for the life of me cant find out HOW to grant them... help!
Found the solution.... Im guessing it had to do with encrypting the files?
Anyways, after I Format Data, then did the whole process again, from factory reset... everything worked fine.

G7+ only boots into TWRP, Files/folders renamed.

I have a Moto G7+ that has been rooted for years with no problems and I have been chasing a solution to a problem of when trying to rename/copy a file on my SD card, it would tell me that I needed permission to access it. After researching this problem, I found a solution to edit the platform.xml (in system\etc\permissions) and add an entry for external storage. I also deleted two downloaded instances of majisk.zip, which I don’t think did anything.
A couple of days later, I restarted my phone and it booted up until it displayed the “unlock for all features and data” screen and then it reboots to TWRP. In TWRP, if I go to MOUNT, the system partition is never checked. If I check it and restart the phone, system is always unchecked. I noticed on my backup G5 phone that the system partition isn’t checked, so this probably isn’t a factor. When I go into RESTORE, I have several restore points, but instead of dates, they all have long random alpha-numeric names.
If I select enable MTP under MOUNT, I can access my phone on my computer through file explorer. All of the files and folders in internal storage have been renamed to random 20+ character alpha-numeric names. I’ve been looking through the forums and I haven’t found any mention of this type of shenanigans.
