Phone does not recognise encrypted storage, please help! - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hi,
There is this bug on LOS16 that if the pop up camera is up and then the device switches off, the camera stays up permanently until a stock rom is reflashed. I had this issue before, so I restored a backup I made on MIUI 10.3.16 using TWRP, but the device was stuck in a bootloop, and the camera was still stuck, so after restoring different backups I made, I decided to finally use MiFlash to fastboot flash MIUI 10.3.16, and I chose the 'keep user data' option, however this also bootlooped and went into MIUI recovery. I reflashed TWRP and now I face this issue:
TWRP does not recognise that my phone is encrypted, and does not ask for my password, so I can see that my files are here, but they have random folder and file names. (example shown below)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I managed to get MIUI running, however it does not ask me for my password, only my Mi account password.
I restored a LOS16 backup I made ages ago, and that also does not ask me for my password - the files I see in the file manager are all encrypted like TWRP.
I attempted the 'twrp decrypt' command, but that does not work either.
I attempted flashing backups and custom roms from a USB, using PitchBlack recovery, OrangeFox, and two TWRP versions.
All I want is for either a recovery or a rom to ask for my unlock password, so it can use that to decrypt my files.
I am not 100% sure if using MiFlash is what caused this, but is there anything else I could try? Are all my files gone? I cannot copy my encrypted files over to my PC and Windows returns an error when trying to do so. Are there any 3rd party tools I can use to decrypt my stuff?
I know I could just wipe my storage and start again, but I do not really want to do that until I know for sure that my files are gone.
I was thinking that MiFlash wiped the decryption keys from my device, but wouldn't a backup restore them?
If it is not possible to save my files, could someone explain why, so I do not make the same mistake again?
Any help would be appreciated.

Format Data, you cant go from miui to aosp or vice versa without doing that. backup your data to pc before or whatever cuz it wipes all internal.

Best thing to do is to fastboot flash again, but use the clean all option.
It's never a good idea to dirty flash when doing anything other than updating a ROM. You might sometimes be OK if flashing from one AOSP ROM to another AOSP ROM.
If your going from MIUI to a custom ROM, or from a custom ROM to MIUI, then it's not worth the aggro you'll most likely get by dirty flashing. Just spend the extra time backing up your data and save the headache.
As for the data, try installing a different TWRP and see if that will then ask for a password to decrypt the phone, before you do a clean install of MIUI.

Cyanogen 4.12.2

Ohh man, i was seriously disappointed in this release. All was good til let CM Updater automatically update the firmware, then all of a sudden my SD card was corrupt.
But wait, i go to "Update from any zip" And my previous installs are there.

First, this belongs in Q&A and as such has been reported.
But, to be helpful, you can manually flash the system.img and data.img from your backups to make sure that it restores the correct backup via fastboot
If you copy the files to your computer (system.img, data.img, and boot.img) to where-ever you have fastboot then you can run the commands in the bootloader:
Code:
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash userdata data.img
and this should be the same as a NANDROID/switchrom restore.
couple of thing - wrong section
the 4.2.x are stored in /sdcard/cmupdater/ or thereabouts and its unlikely they are all corrupt
its your own fault for not doing a nandroid of a CM (you may have an old one in there if you went to hero after cm and then back again)
if not, start again with 1.6 then CM
CM doesnt screw your sd, improper use does
I am seriously disappointed with your post.
why-o-why do we let people with less than 50 posts create threads anywhere but the QnA?
ZALGO - that was wrecking-crew-esque....let me shake your hand
i miss those guys....
ohh stfu -- all you, i have been flashing PC bios for years, but i "update" my phone with and automatic update, and you jump on my back. and where so you think i got my information to flash my phone. "YES" xda.. so swallow it up.. Question is there a thread for the new Cyanogen 4.12.2 release, if so point me to it. THANKS!!!
fukin look for it you lazy buggar
its staring you in the face...infact it was 2 under your thread when you first posted
and so what if you flash pc bios(s) all the time, this is even easier, you dont even need to push a button until its finished
I'm new with like no post an I can tell your a tool. Do a little search douch nozzle. I am a noob and I agree garok89, no new threads for noobs outside of Q+A before they can show there not tools like this douch who started the tread
cm updater could do with the option to do a Bart / Switchrom / Nandroid backup though.
I have clicked apply now many times and forgotten to manually reboot and do a backup first.
If it fails I just curse myself, but it would be a nice feature.
the cmupdater can easily have the feature to autonandroid - we have the code for it
only problem is, none of the recovery images support it
the second its supported in cyanogens recovery image (and therefore RAs recovery image as it is based on cyanogens) we will enable the feature
reading is the best way to avoid these types of problems.
but lets face it, this is total....

Downloads
TWRP For P10 lite: HERE
ADB & Fastboot: HERE
The first step is to make a backup.
2. Download your Treble ROM, i recommend a GSI ROM.
In my case I'll be using Havoc-OS
Download: https://forum.xda-developers.com/project-treble/trebleenabled-device-development/rom-havoc-os-8-1-t3819050
3. Go into TWRP and do a FACTORY RESET and then reboot into fastboot.
4. The only thing you need to do now is flash the ROM, so get your downloaded ROM & extract the .img file from it (if there is no .img file and you see other files, flash via twrp).
On your PC open the fastboot command prompt and type
fastboot -u flash system <YourImageFileHere>
Click to expand...
Click to collapse
After just type : "fastboot reboot" and wait until your phone boots into the system. You may need to flash google apps afterwards.
It is normal for the phone to reboot a couple times so be patient.
Congratz, your phone is not running a treble ROM with your stock ROM's vendor.

I just need backup Boot, System and data if i want go back to stock?
Bad idea to factory reset with TWRP, it doesn't do it clean enough.
You could get in serious problems by doing it, such as random apps crashing, sd unmounting and worse.
Safer option is to factory reset and wipe cache with stock recovery after every system flash.
I'm telling this from my own experience, I don't want people to mess up like I did :highfive:

Yes that should be enough, vendor stays the same anyway.. I recommend flashing roms designed for kirins cpus btw because there is a higher chance it will work

Question Can't install Xiaomi EU ROM - Stuck without a ROM

I've followed the process outlined here. After installing the ZIP, it rebooted, but went back to recovery. When I said reboot system, it said No OS installed.
So, I tried to start over by formatting data and then copying the zip again via ADB Push. Then the trouble starts. After adb push, which takes about 5 minutes, it says
Code:
failed to copy 'xiaomi.eu_multi_HMNote10Pro_V12.5.3.0.RKFMIXM_v12-11.zip' to '/sdcard/xiaomi.eu.zip': write failed: No space left on device
After that, the data partition seems corrupted. Whenever I go to Install, it shows 0 bytes. Upon Googling I found a solution by formatting to ext2 and back to ext4. Then, it shows again as 100000MB. However, adb push every time fails with same problem.
For some weird reason, I can push to /data. But still running into same problem after installing ROM and rebooting, it goes back into recovery.
I also tried to sideload, but then I run into this issue:
Code:
D:\Tools\ROMs>adb sideload xiaomi.eu_multi_HMNote10Pro_V12.5.3.0.RKFMIXM_v12-11.zip
loading: 'xiaomi.eu_multi_HMNote10Pro_V12.5.3.0.RKFMIXM_v12-11.zip'
* cannot read 'xiaomi.eu_multi_HMNote10Pro_V12.5.3.0.RKFMIXM_v12-11.zip' *
So, I'm stuck with a device without any ROM. Any suggestions please?
Did you ask in the MIUI EU forums as well? Since there would be more ppl familiar with these issues than here.
I'm also interested in this since I prefer EU roms. Also you need a specific TWRP version which I believe is still in alpha stage for the 10 Pro since its still a new device. There should be a TWRP thread somewhere here where you can also ask.
I just got my 10 pro and need to wait a few more days to unlock BL, then I will be flashing an EU rom, hence my interest. Hope you find a solution.
Use TWRP from here:
https://forum.xda-developers.com/t/4248449/
fastboot reboot bootloader
fastboot boot TWRP_file_name.img
Format Data, type yes.

"lightbox_next": "Next",

}
Reboot to recovery.
The internal storage should be visible.
Connect phone to PC and put ROM into phone.
Flash ROM, format data, yes
Reboot to system.
If above not work, make your phone under fastboot mode, Mi-Flash, and flash your stock fastboot MIUI. Don't lock your bootloader.

When I try to flash a custom ROM I always end up with this, and the device only boots to TWRP Recovery

What could be the cause?

Xiaomi protect their device from custom rom or custom recovery and some time device go to hardbrick and stock on fastboot mode
So every time you want to install a custom rom after successful to install(dirty flash better) the rom first go beck to twrp menu and format system and dalvik cache then go to install>install image>select twrp img file>install
Then go to reboot>reboot to recovery
Then reboot to system
I don't have your device. But that list of files/folders with random letters means your internal storage/data partition is encrypted. You need to go to "repair filesystem" menu in twrp and reformat it to another type and back to ext4. Or use "format Data" menu. All your data will be wiped.
Don't take my word for it. Google "how to decrypt device in TWRP" and learn about it.
Ps: @moh4556 your answer is correct but it's not format system and dalvik, it's wipe system/dalvik/data menu. It will delete those partitions but for data it leaves /data/media (your internal sdcard) alone. It's sometimes not enough when moving from stock to custom rom.
Hope this helps
weird, i was pretty sure i replied to this thread
strange characters in roms mean you havent formatted data most of the time. once you answer yes you lose your entire data (and locking mechanisms which scrambles names) altogether
for the most part, installing roms follow the same steps
format (not wipe) data
wipe system, vendor, dalv and cache
flash stuff
wipe dalv and cache again

not entirely true. it is highly recd to install the vbmeta patch for redmi8. im lucky and havent required it.
newer miui does make it a pain to install custom recovs directly, hence the 3.6 update included an advanced install option
older miuis arent that protected and only require a reboot to recov after installing the custom recov
also a bit offtop but whatev

What file format is pictures exported as a backup from the phone?

Hi,
My Huawei P20 Pro broke, but earlier I did an backup of Pictures on it using Huawei HiSuite if I remember correctly. Now I tried to open those pictures on my computer but got this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then I tried to open using ImageGlass but got this:
Then I checked if Linux file command can identify if it's an jpg file and it can't.
file IMG_20190428_115443.jpg
IMG_20190428_115443.jpg: data
This is because Magic bytes of the file starts with 6425 b4a7 which doesn't match JPG magic bytes https://en.wikipedia.org/wiki/List_of_file_signatures
It does not match file on that page.
So what kind of images are these?
Have you been asked to set a password before you did the backup?

Nope not from what I remember.
When was that backup done and what was the HiSuite version? It used to create the backup by just copying the files from the phone, but since some time (I believe few years now), every time when you start creating a backup, it is asking to set the password and then all the files are being encrypted.

The backup was done 2022-07-26 and I used HiSuite version that was used at that point since I downloaded it when I backed it up. So I don't exactly which version it was.
If you've downloaded the newest version at that time, it was surely the version, which is always asking to set a password, when the backup is done. Your files are encrypted and you need to decrypt them (if it's even possible) or rather restore a backup on your phone (but you need to know that password anyway).

I see. But yeah since the phone broke, I can't connect a phone to HiSuite on my computer and restore them. I would need to have the phone for it which sucks..
I tried downloading HiSuite on my computer but can't import the folders I have from the backup into it because it wants to connect to a phone first..
