Rom Access or advice for TAB S4 - Samsung Galaxy Tab S4 Questions & Answers

My device was fine before Rooting importantly the Bluetooth stack was was also fine. However, after rooting all BT Pairings are lost across reboots etc. Just turning BT off then on again causes the issue making it necessary to delete and re-pair every time the device starts. over the last week i've ran various tests, and concluded the issue lies with either the hardware or the stock image i got from Sammobile.com. Being a noob, during my experimentation i have had to flashback to the stock image on several occasions. Only discovering the Bluetooth issue when putting my work to good use and using the device.
Yesterday i tested the theory. Flashed it to stock, booted to OS and skipped all the config disabled WI-FI and DATA so it couldn't pull updates. Tested Bluetooth and the issue is present. The Bluetooth did work correctly before i started rooting it. This is unlikely a hardware issue so can only assume its an issue in the build i have from Sammobile. If any of you have access to a stock pre-installed rom that works that they could give me access to, so i can do some testing or indeed any advice it would be very much appreciated.

This is known issue once rooted, however it has already been fixed. There is a module that you need to load via Magisk. Search for: libsecure_storage companion for rooted Samsung devices. Load that up and you'll be good to go.

thanks for the info, i saw a few threads a few days ago about secure storage and did it manually which didn't help with the issue. similarly neither does the module for Majisk . a case of keep looking i guess. any other suggestions will be very much appreciated

Hmm, I would try uninstalling and reinstalling again via Magisk to confirm. I have rebooted multiple times and the bluetooth pairings stick for me. I do have T830 vs. the T835 that you have but I wouldn't think that it should matter. Worth another shot anyway.

Cheers will give it a go - at this point i have nothing to lose, just taken a fresh backup so nothing ventured nothing gained

its stuck no boot while removing secure_storrage module from majisk
Oddly having tried the suggestion above of removing the majisk module the device no longer boots it gets stuck on the Samsung logo. For some reason the vendor partition is no longer able to mount.. Completed a restore eventually to get it to boot. Disabling the module yields the same result. no vendor partition and no boot. Going back to an earlier backup prior to the module being installed

The plot thickens
Today i'm still trying to find a fix for disappearing Bluetooth devices. Using the Magisc module cases my Tab to stall during boot on the Samsung logo similarly trying to replace the /vendor/lib and /vendor/lib64 binaries manually also causes the system to freeze on the Samsung logo. looking at the binaries and some path file references there in. It would appear as though my tablet is missing some key files or folder so far the following are missing
/data/system/secure_storage/ls_data.db
/dev/.ashem.secure_storage_ashem
/dev/.secure_storage/sd_socket.ro
any of you have any thoughts

You actually only need to replace the libsecure_storage.so libs and set the correct permissions.
Add the following to the build.prop:
ro.securestorage.support=false

No matter how i do this, the device failes to boot and gets stuck on the samsung logo.
Install the majsik module through majisk reoot when prompted = device brick
making all the changes manually including the changes to the build.prop in the /vendor partition = device brick on reboot.
Tried Using instructions and librarys from the following post
https://forum.xda-developers.com/sa.../guide-fix-bluetooth-losing-pairings-t3798262
Although, the above post says to replaces the libs in the system folder which serves no purpose but replacing them in the vendor partition causes the device to brick at next boot.
Thanks far the suggestions, Still looking

Is this happening with only the storage libs or does it happen if you make any other changes to vendor?

Thanks for the assist
It occurs only when the Libs are changed.
Originally using the majsic module to install the libs it couldn't overwrite the files as they are in use. modifying the build.prop seemed to resolve that but as soon as those libs are change either manually through terminal or via the installer i end up with a soft brick LOL
its Bugging me!!!

Interestingly
Once the device hangs.
Simply restoring the vendor partition doesn't fix the boot issue.
In order to get the device to boot I have to restore /data (you don't need to restore /vendor just /data)
oddly restoring the /data partition restores the 2 library files in /vendor to their respective originals

Majisk zip extraction issue
so I have resolved the Bluetooth issue, Rather having majisk install the module i just downloaded it and extracted the contents and discovered that upon zip extraction the contents of each file were appended to themselves. see screenshot "confused.jpg" of the readme.md - so in relation to the library files, the files being installed were double in size hence corrupt.
ie /vendor/lib/secure_storage.so should =308kb the file being insatalled in my /vendor/lib partition was 616kb the 64 bit library was also double the size it should have been.
infarct all the files within the Zip had the same issue.
so i extracted the Zip contents on my pc and transferred the library files via usb. made the relevant changes to build.prop and stopped the secure_storage deamon. Machine now boots and Bluetooth pairings are retained across reboots.
Small Wins
Any one have a clue why the files would double up on content??????

built in zip extractor
the issue i have is with the stock zip extraction tool.
extracting the zip file content on the tablet with winzip. the files are as they should be

NAND Testing - 05-25 Update: New LK, Recovery.img, Kernel Updates through Recovery

THIS IS FOR TESTING ONLY. DO NOT ATTEMPT TO INSTALL THIS IF YOU DON'T KNOW HOW TO GET INTO BOOTLOADER MODE AND FLASH A ROM FROM THE SD CARD.
Announcements​
We are currently replacing Tinboot with LK for boot. This will give us fastboot and many other enhancements and fixes to make our device more like a native Android device. This has already fixed some issues with GSM phones, sleep modes, and a few other things. The current issue being worked on is the power button not working (possible GPIO issue).
Introduction​
This thread tracks the most recent NAND development. A huge thanks to [ACL] and WoZZeR999 for dedicating time to NAND development for us, and again, thanks to Jonpry, PHH, stinebd, and the rest of #htc-linux for their contributions. It's truly amazing what these guys have done for us, so be sure to show them your appreciation :wink:
The original NAND boot testing thread can be found here:
http://forum.ppcgeeks.com/tp2-andro...und-test-7-single-nbh-serialno-tilt2-fix.html
File Repository​
Autobuild files can be found here: Index of /files/
The LK directory will contain the latest LK Bootloader and boot image code.
The rhodium_nand directory contains the latest kernels
The XDAndroid directory contains the latest OS files and updates (including the root update)
Note: We often disable autobuild when extremely experimental code is submitted, so this may not always be up to date but should be more stable than content we post in the threads.
Latest Files
LK Bootloader: http://htcdevs.wirelesstcp.net/files/LK/RHODIMG_NORECOVERY.NBH
Recovery Image: http://htcdevs.wirelesstcp.net/files/LK/recovery.img

Optional - FRX06 Root: http://htcdevs.wirelesstcp.net/files/xdandroid/opt_updates/Root-Update.zip
Installation Procedure​
Obtain Install Files
You need 4 files to get NAND up and running:
LK Bootloader NBH
Recovery.img
Kernel
OS Files
Install Directions
1) Set up your computer to use fastboot: http://forum.xda-developers.com/showthread.php?t=532719
2) Flash your phone with the LK Bootloader NBH
3) Copy recovery.img to your fastboot/adb folder
4) Open bash/command prompt and run fastboot flash recovery recovery.img
5) If successful, type fastboot reboot, and hold the Power Button as your phone boots
6) Your phone should boot into recovery, and there you can apply the various update.zip files in this order:
- FRX06 Update.zip
- Kernel-Update.zip
- Root-Update.zip
To navigate in recovery, use volume up/down (or up/down on keyboard) to change selection, then use End Call key (or Enter on keyboard) to make a selection.

Frequently Asked Questions
What is NAND booting?
NAND booting uses code on the NAND to boot directly into Android without having Windows Mobile on the device. Currently, zImage and initrd.gz are stored on the internal NAND while the modules, rootfs, ext2, and data are stored on the SD card.
How do I setup NAND boot?
First, you need to download the Update Utility (CustomRUU) and the latest package. Extract the NBH to the same folder as the Update Utility and flash like you would a custom ROM. Put the included modules on the SD card (modules must be from the same package as the NBH) along with the modified rootfs.img (see first post) and system.ext2 from http://xdandroid.com/wiki/Main_Page (you can use system.ext2 from BLAZN, but XDAndroid will be better for testing)
Why don't my changes to Startup.txt work/How do I change boot options?
Because we are booting without Haret, Startup.txt is not used. Any changes to Startup.txt will have no effect. If there is a boot option you need enabled, you can either compile a new tinboot with those changes or let me know and I can compile one for you.
Where are the Android files stored and how do I update them?
Modules, rootfs.img, and system.ext2 must be stored under /andboot on the SD card. Every update will require flashing a new NBH (contains zImage) and replace the old modules file with the new one. Sometimes deleting the data.img file is necessary between builds if you experience major problems.
Wifi or other devices aren't working after an update...
The modules and zImage are a pair and must always be updated together. If you only flash the NBH but don't replace the modules file on the SD card, you will get a mismatch on the modules preventing the drivers from loading.
My battery drained and now my phone is stuck in a boot cycle! AHHHHHH!
Don't worry about it. You have two quick and easy options. First, unplug the USB cable, then remove the battery, then put the battery back in, and plug the USB cable back in. Now let it charge for 5 minutes, then turn it on, and you should be good to go. If it still does not work, unplug the USB cable, then remove the battery, then put the battery back in, attempt to enter bootloader mode and plug the USB cable back in as soon as the bootloader screen comes up. Now you can charge it for 5 minutes and restart back into Android (where you should continue charging).

First of all i want to thank all devs who are involved in the NAND Booting Section. I think i will test this in the next days but i must ask some questions first to do it .
1. So, do i need to do the Task 29 or is it just in case of problems.
2. Am i able to flash WinMob back if i'm failing?
yes u can go back to windows. infortunately i have been following all the steps correctly and it loads up the with letters showing its working and then i get a black screen so i think im stuck at boot any help. can someone tell me what im doing wrong. the files are in sd card/ andboot

Task29 is just recommended to make sure everything is nice and clean. It makes troubleshooting much easier because it ensures nothing weird is being read from the internal nand.
You can easily flash back to WinMo by starting the phone in bootloader mode and flashing. Unfortunately, you will not be able to do the ActiveSync connection through USB and flash that way.

You should have three files in /sdcard/andboot: rootfs.img, system.ext2, and modules (don't rename the modules). Now flash the NBH and it should generate the data.img, and you should be good to go. It should be loaded in under 10 minutes, so if it isn't, I would check the contents of the memory card. Also note the card must be FAT32 formatted and have not be partitioned.
The panel power on/down is apparently fixed for some panels but not others. ACL and bzo have been working together on this and found that there are several different panels being used in our phones, and ACL is working on a patch to fix up the panels that aren't functioning perfectly.

RootFS
A custom rootfs.img is required to automatically configure the keyboard. You can override the automatic keyboard by creating a .kb file in your andboot folder. Accepted inputs are: rhod500.kb, rhod400.kb, rhod210.kb, and tilt2.kb

What about the rhod100? I have a modified rootfs.img for correct german keylayout in haret version of xdandroid. Can i use that too or do i need to delete all other .kb's? And is it even possible to get a working rhod100 keyboard? I know many questions but i think this should be BEFORE i get lost .

Ahh yess the custom keyboard and how to create it. This threw me for a bit too and when i realized that all I had to do was open up notepad and then do a saveas rhod400.kb, I laughed at myself.
yep that easy a blank text file with the correct name and you are good to go
Well now that the thread is over on xda I tried again but still to no avail even tried two different SD cards both end with it booting but freezing at SMD: ch 0 OPENING -> OPENED. Pretty sure I have everything setup correctly three files in andboot folder on sdcard renamed rootfs to just rootfs.img but left the other two files. By the way this is on a tilt2.

Actually, I didn't account for the non-US variants when creating the rootfs. I have some other modifications that I'm testing for the rootfs at the moment, so I will be sure to add the other variants back in for at least the KB overrides. I will need help with a variable for the automatic detection to work properly.
If anyone has any of the non-US variants, it would be extremely helpful for you to flash to NAND, hook up to ADB, and run "cat /sys/class/htc_hw/machine_variant" and let me know what yours is.
wifi
i want to start off by saying this is an amazing project.
But my problem is that wifi is not working for me. When i try to start wifi, it immediately says "error." I have done many flashes and used task29. i was just wondering if anyone else had this issue.

I'm using Neopeek's rom instead..how can i set it up? since this rom doesnt use the system.ext2 file
getting calibration without visible points to touch aka the boxes. also, boot ani glitches out on screen with a "solid" animation, and video glitchs on the bottom half of the screen. sits here indefinately.... still waiting..... haha
update: loads to lockscreen, so far can't get screen to stay on??? strange
update2: got it working, but keeps turning screen off immediately... any ideas>?
hmm, i have been trying this and i feel like i have everything right
tilt2.kb, rootfs.img, modules, and system.ext in an andboot folder in my storage card and then, a nbh with the same name as the module in a folder with customRUU.exe. I flash and then it gets to the linux boot screen, after a couple lines go by, the screen fades out and dies and restarts. My battery says 88 percent when i flash back to windows, anybody know what could be going wrong?

Android 7.0 & /etc/hosts

/etc/hosts blacklist entries seem to be ignored with Android 7.0 (e.g. adding 127.0.0.1 amazon.com still allows me to reach amazon.com). Is anyone else experiencing something similar or familiar with any gotchas around Android 7.0 and modifying /system/etc/hosts?
I'm running official Nexus 5X Android 7.0 build number NRD90R. I have an engineering build of android that I boot from as follows to modify my /system/etc/hosts file:
adb reboot-bootloader
fastboot boot my-recovery.img
<mount from phone menu>
adb remount
adb push my-hosts system/etc/hosts
adb shell
chmod 644 system/etc/hosts
exit
<reboot from phone menu>
I've been using this process after every OTA update since Android 6.0, and it's been working. I also noticed that I'm not getting the red warning on boot any more (the one you get after you modify anything on the system partition), just the yellow warning (the one you get from having phone unlocked). Maybe I did something wrong ¯\_(ツ)_/¯ but I could sure use a sanity check.
Could be related to java cache, after a modification to hosts file you should reboot to let the cache reload. Try it.
The OS is not booted when editing hosts since it's being edited from a recovery image with the system mounted into it. The last step is to reboot. I did reboot the phone again for good measure and it's still not working. If it is a cache related thing, it lives through reboot. I suspect it's not though as I was seeing ads in news websites that I do not frequent.
Any other thoughts?
Are you using chrome? Did you disable data saver option in chrome?

Seems to be related to: http://forum.xda-developers.com/nex...oid-nougat-t3445647/post68737720#post68737720 . Basically the files that one would modify by mounting /system are no longer used, afaict.
When I boot a live image, mount the system partition, and make a modification (i.e. /system/etc/hosts), that change is persisted through a reboot back to the live image and remount. However, it's not loaded by the OS when it boots. Instead both /etc/hosts and /system/etc/hosts are unmodified. Odd, and why is there even anything mounted at /system? I'm not sure if there are multiple system partitions or what's going on. I would love to find some information about Android 7.0 that explains.

I responded to your post in the other thread. This is repost.
Android 7.0 introduced redundant bits for reed solomon forward error correction into the system and vendor partitions and code in the kernel to perform the error correction.
Your changes are being written to emmc but when you boot with 7.0 kernel with dm-verity enabled your changes are being treated as data corruption and on-the-fly error corrected back to original.
You can see your changes if you boot into twrp because it has dm-verity disabled. However if you boot into android with dm-verity enabled it will look like original image again even though your changes are technically still there.
It took me a day to figure out what was really going on because i initially had no idea they added this feature to Android N.
The simple way to disable dm-verity is to install SuperSU, but you can also accomplish the same patching your own kernel, installing pre-patched kernel, installing custom kernel, etc.

That's good info and makes total sense. Thanks! Pretty neat actually, just a bummer for me.
Yeah so SuperSU path is not really one I want to pursue. I could learn how to update the dm-verity shas used for verification. That'd probably be the most secure, but it's gonna be a PITA I bet. I imagine I'd need to compile my own image similar to how I made my live image and update a few things. Might have to deal with encryption which is probably an even bigger headache. Also, I bet it would break OTA and have to reflash to update, though that's true now.
I'm really curious what AdAway is doing. Maybe I should pursue reverse engineering that.
I really appreciate you pointing us in the right direction.

I don't use adaway but I believe there are 2 ways to install it with Android N. First is to install SuperSU (or otherwise disable dm-verity) and have it update as it always has. 2nd way is systemless where it piggybacks on some init scripts SuperSU has created to mount "over" the existing hosts file. Basically like symlinking but using a mount point on top of the existing file.

I'll probably try to go the route of updating init scripts to mount over the existing host file but without using SuperSU or AdAway.

Perfect thx that explains a lot..
As you mentioned already the bootloader stack thing but also another one you flashed 21y modem .. I will need some time to investigate both things and come back to you asap
Update:
ok so the worst thing you had done was flashing the 21y modem. The problem with that one is that it is ARB 3 (see known ARB) and so blown fuses (in areas not related to the bootloader ARB but for firmware).
Anyways that will refuse using several parts of your firmware now.
There is no guarantee if the following would make things even more worse but that's what I would try:
extract the system and the modem partition of the 21y kdz
grab the "etc/firmware/venus.*" files from the extracted system partition and copy them to system/etc/firmware/ (mount "system" in TWRP before)
grab the "image/a2dsp.*" files from the extracted modem partition and copy them to /firmware/image (mount "Firmware" in TWRP before)
boot again and grab the dmesg as soon as possible
again that can make things even more worse so you do this on ur own risk.

Before I do this, because hell why not , is the 21y here https://storagecow.eu/index.php?dir=Xda/LG+G4/H810/AT&T/ what I am looking for? Want to be sure before I make matters worse for myself.

Yes the rar file. It will contain a TOT file (so you cannot use SALT to extract) .
TOTs require the windows software :

How do I grab the files out of system.img . I had to use WindowsLGFirmwareExtract-1.2.1.0-Release as the newest one would dump 20G+ junk files.
Code:
$ file system_691200.bin
system_691200.bin: Linux rev 1.0 ext4 filesystem data, UUID=57f8f4bc-abf4-655f-bf67-946fc0f9f25b (extents) (large files)
I can't mount the file, after making it the size it wants with "truncate -s $((1159168*4096)) system_691200.bin" it will mount but then is completely empty. Repairing with fsck annihilates everything. What is the trick to dumping/mounting this?
modem.img mounted fine.

The latest should work fine but you have to merge (!) the files once extracted which is a separate option in that tool. For mounting you could then use SALT (advanced menu) if you like
Sent from my OnePlus 6T using XDA Labs
It only extracts one system file, system_691200.bin, there is nothing to merge. That's with 1.2.6.1, I tried several different versions and all of them only list/extract one file. The tot I used is not corrupt (i believe), downloaded 3 more and they all had the same md5.
Do you know offhand if I would be able to push the system_691200.bin onto the phone and mount it just to grab those files?

ok when it lists only 1 file there it is only 1. Lemme check if I can do that today.
EDIT:
ah yea another reason why I hate that windows tool.. it extracts bull****.. trying to fix that but that can take some secs
EDIT2:
wow thats is really a stubborn crap.. Cannot mount, resize, fsck, fix, testdisk/photorec , ... (and yea I used DD to get the correct size, offset ...)
EDIT3: @baconbacon
no one is as stubborn as me lol..
ok I have not figured out why that crappy windows software does not extract it correctly but I searched and found another extractor here. (whoa.. that way I could make TOT files support available in SALT...)
compiled. ran. mounted. simply works..
so here you go: http://leech.binbash.it:8008/stock/LG/h810/21y_arb3
you just need: h810_21y_ARB3_system-etc-firmware.tgz
download that one.
extract it and follow the prev post here
jfi:
I am currently uploading the full system image and other stuff of that firmware as well (should be fully uploaded in 40 min or so)

That fixed it completely! Sound works, rotation works, camera works. Installed the newest rom and the phone is quite snappy now. As a bonus it also fixed the video lag.
Thank you very much, you went above and beyond to help me fix this. Is that bitcoin address on your profile accurate?

GREAT ! Glad we solved it.
I really hoped it will fix it and yea that's again a proof of fusing in modem and firmware files (due to flashing the 21y modem).. I will remove that one from the list so no one will go for the same journey.
yea my BTC is fine but given some thx click on any of my posts is fine too

[GUIDE] Recovering from a magisk bootloop without twrp

Just to add my experience here, I flashed MARS_SOM magisk rom module which entered a seemingly unrecoverable endless bootloop. This was likely as it conflicted with another magisk module or xposed that I have installed, so not the fault of the rom!
However given we've no twrp yet, the best way (after a LOT of research!) to fix this wasn't easy or obvious. I thought I could just flash stock kernel, uninstall magisk, flash magisk again and uninstall the module. Which unfortunately you can't as they remain in the system files and without root, you can't touch them, though with root, it loads and you get the bootloop - so a vicious endless cycle!
The solution I managed to work out, rather than a full clean wipe was to extract the stock boot from downloaded firmware (using Xperifirm), convert it to an img file using UnSIN, use to unpack, place a certain folder in there (found via the link below), repack and then fastboot flash. This makes magisk operate in core root mode only allowing you to uninstall the module. Once the module is uninstalled, you can simply disable core only mode from the magisk settings.
This saved me from a full wipe!
See here for more details about that unpacking the img, copying a folder etc see here:
https://forum.xda-developers.com/pi...modules-disabler-booting-magisk-t3976621/amp/
This worked for me and so hope it helps someone out too!

Hi there; I was in the same situation, flashing a corrupted magisk boot image from standard firmware for XQ-AT51, provided by same author for simple rooting Xperia 1 II; my phone was without xposed, it was in clean factory state. the magisk boot image was taken from another thread "[ROOT] Magisk patched Boot Images & Instructions" designated for rooting of Xperia 1 II;
unfortunately is the same author who build your ROM, he delivered also corrupted magisk image.
It was not enter in bootloop if you flash only one image on phone, not both; his instructions are wrong. the correct flashing instruction is below, at end of my comment.
I solved in smilar way like you: using flashtool to obtain XQ-AT51 ftf file: XQ-AT51_58.0.A.3.39_1321-7706_R13A.ftf;
Attention: the name of file depends of region firmware you want to flash and type of phone (single or dual sim); the given names are with title of example.
Then from download folder of flashtool form your disk C:\Users\username\.flashTool\firmwares\Downloads (username is your username on pc); check for file: boot_X-FLASH-ALL-2389.sin ( applicable for XQ-AT51) and convert the file to .img using unsin; check on xda for unsin, extract unsin archive in exe file and then drag & drop over unsin.exe the file boot_X-FLASH-ALL-2389.sin; will be generated boot_X-FLASH-ALL-2389.img file.
This name file can be other, is just an example, if you have another phone with firmware for other region, pay attention to this!
This can be flashed then back to phone using adb comands; fastboot flash boot boot_X-FLASH-ALL-2389.img;
The same image can be transfered to phone and used later to generate correct magisk image and root the phone.
Best to you all!

Wait until your device is fully rebooted before opening apps [REWARDED]

Hello friends!
I need a lot help.
If I fail to repair the operating system and work as before, I am impetuously interested in recovering at least the data on the /sdcard (internal phone storage) because I HAVE NO BACKUP and I need that data lke the air.
I have a Xiaomi Redmi Note 8 (Ginkgo) with stock ROM MIUI India/Global (11.0.6.0.PCOINXM), TWRP (3.3.1.0) and Magisk (v20.1 or 20.3 - I don't remember exactly).
About two days ago Revolut no longer allowed me to use the application because the phone is rooted. I needed to make an immediate transfer, so I started playing with Magisk because it didn't pass the SafetyNet test. Until then I had installed only Magisk, I updated to the latest version v21.2, I also installed two modules: MagiskHide Props Config (latest version) and Universal SafetyNet Fix v1.1.0. Plus the latest version of TWRP (3.5.0_9-0).
After running "props" in the terminal, I followed the steps (1, f, Xiaomi, 71 ...) and selected my phone from the list I managed to pass the SafetyNet test, but Revolut still did not work.
After that I tried to disguise the Magisk application with another name to hide it (that's how I saw it through some tutorials), but without success because I didn't activate install applications via USB (something like that).
I left the phone for about half an hour, and then the PROBLEMS BEGUN.
For each application I want to launch I receive the following message "wait until your device is fully rebooted before opening apps". I restarted the phone countless times and nothing. I noticed that TWRP does not decrypt user 0 or 999, so I changed TWRP to the previous version, uninstalled Magisk, deleted the modules from /data/adb/modules, upgraded to MIUI v11.0.6.0 and then MIUI v12.0.1.0 - and the problem persists.
I mention that using TWRP File Manager all the content from /data/data and /sdcard is encrypted (files and folders have unintelligible names). The rest of the files are ok.
Although developer mode is enabled, I don't have USB debugging enabled, and the default USB connection is set to charging and as I constantly get the error "wait until your device is fully rebooted before opening apps" I can't change them.
When I open the phone, at the lockscreen, I have a pattern that I successfully insert and the phone opens. The same pattern in TRWP does not decrypt the data.
Given the fact that it accepts the pattern password, I think that if I had a USB connection I would have managed to recover decrypted content from the internal storage space of the phone. Or is the error I receive exactly due to the fact that the applications no longer have access to the content because it is encrypted?
If so how can I recover all the encryption keys to backup them and then how can I try to fix this problem? Or if the keys have been altered, can they still be generated again (if the phone is the same, as well as the IMEI or serial number, etc)?
I understand that if I solve this problem I will either recover my phone as before or at least I can decrypt and access the data and make a backup.
It is very frustrating to see that the necessary information is still there, but I cannot access it.
Because I have access to the system with TWRP, I think I can attach logs.
I hope no one feels offended, but I am so desperate that I am willing to pay a reward.
Please help me!
Here is my video for a better understanding.
https://www.dropbox.com/s/ob235116jpnbj/ginkgo.mp4?dl=0
When I used MagiskHide, it changed my default.prop
Is it possible that the above problem is due to this fact?
How can I copy default.prop (original from wife's phone - same model) from SD card to phone?
Nothing changes with TWRP File Manager copy/paste. Can a script be used to be flashed with TWRP?
Any prop changes that were made with MagiskHide or MagiskHide Props Config did not touch any of your actual prop files. Your default.prop (and any other prop files) are going to be exactly as they were before enabling MagiskHide or changing prop values with MagiskHide Props Config.
Magisk does these things systemlessly, which means it doesn't actually alter the files. This (default.prop) is not your issue... How did you come to the conclusion that Magisk had changed your prop file anyway?
Since you've uninstalled Magisk and the modules, and even updated your OS and the problem still persists it is unlikely that it's directly related to Magisk. I know very little of MIUI though, so I'll leave the rest of the troubleshooting to those that do.
Thanks for the help and for the reply!

I see a difference between my file and my wife's, although the phones are identical and had the same version of the operating system.
Originel - ro.bootimage.build.fingerprint=xiaomi/ginkgo/ginkgo:9/PKQ1.190616.001/V11.0.2.0.PCOINXM:user/release-keys
Actual - ro.bootimage.build.fingerprint=Xiaomi/omni_ginkgo/ginkgo:16.1.0/PQ3B.190801.002/5:eng/test-keys
Maybe I'm wrong, I'm trying different options...
In the end, I'm only interested in being able to access the decrypted content from /data and /sdcard (the internal phone storage) to backup them. Later I will reinstall everything.
Please help me with some tips, ideas, what else can I do?
If I reinstall the same version of MIUI, TWRP and use the same pattern can I decrypt the data (If I finally manage to backup them).
I'm already trying without success for about 2 days, do you think there is any chance to recover the DATA and/or internal storage (most important)?
Or to transfer it encrypted and then set the same pattern and eventually restore the data after I format and reinstall everything?
If I reinstall the same version of MIUI, TWRP and use the same pattern can I decrypt the data?

That fingerprint wasn't set by Magisk... Looks to me like you've been running a third-party/custom ROM and then didn't do a clean install of MIUI when going from the custom ROM. If so, that's a very likely source of the issues. I'm just guessing wildly though...

Until 14.01.2021 when Revolut no longer worked on rooted phones, I had the MIUI India 11.0.2.0 version installed. Nothing else. Later in trying to make it work I kept switching between various official versions 11.0.2.0 / 11.0.6.0 and 12.0.1.0, flashed thru TWRP or Mi Flash (with save user data method).
It worked perfectly until I made those settings described in the original post. The problem is elsewhere, I think.
Based on the information in the attached file are the system encryption keys generated based on software or hardware?
Because if is hardware, I still have a chance to recover something, but if it's software, the fact that I tried to switch between versions decreases my chances to recover something.
What do you think?

After I upgraded to MIUI 12.0.1.0 with MiFlash now I can't downgrade to 11.0.2.0. In logs everything seems to be ok, but the phone don't boot entering in recovery.
Trying to flash any other custom ROM, do you thing may be a solution? Or I will make things worse?
How can I resolve this situation?
If the fingerprint is the problem of FBE decrypting, how to restore the correct prop.default file?
Is any recovery that allow me to edit this file like text?
I have a copy of original prop.default.
Hey, did u mange to find a workaround? Im having the same issue, so frustrating!
