[General Questions and Answers] alecxs:
I think you misunderstand the encryption part. still the whole userdata partition is encrypted. FBE is even more secure than FDE. assuming you have some kind of raw access (which you have not), assuming you can somehow mount f2fs partition (despites the inline encryption), most if not all file names are just 0Y7NnLW1JghbWJwbzL1WIpQw7nkzQoH9dEwvTiloTg5BI1u9TYRExzLGQEDUqN2hjq1G5cn looking garbage.

In any case, it requires booted android, no offline decrypt on PC is possible, no custom recovery can decrypt, no chip off, JTAG, nothing.

Furthermore it requires root access. on stock device it's maybe easier to re-enable packages from package manager (no root required).

adb shell pm install-existing <pkgname>

But of course, in case you can install combination ROM without data loss and boot into android in stage where at least adbd is started, you can try adb root and delete the entire file (even if system_server is still crashing).

edit: just one more thought. you may have future idea to dump raw userdata partition from JTAG, unlock bootloader, root the device, restore raw userdata partition afterwards - just forget it. bootloader state is involved in key derivation, if it changes, encryption keys become invalid (refer to last link "Cryptographic relation between Verified Boot State & FBE keys").

Does File-Based Encryption (FBE) in contrast to Full-Disk Encryption (FDE) allow deletion of individual encrypted files?

As far as I understand, Android 9.0 switched from Full-Disk Encryption (FDE) to File-Based Encryption (FBE), which means that encryption is done on a file-by-file basis by default. If Android no lo...

stackoverflow.com

Assuming that it's possible to identify the memory bits that make up this file, the next question, of course, is whether or not it's possible to flip them. But this seems to be the second step...before that, the question is whether or not it's possible to identify the file inside the memory. Write access comes next
[General Questions and Answers] alecxs:
ähm.. no! write access comes first. that's exactly your problem you don't understand.

even if device would not encrypted at all, there is no way to read userdata partition off the device. encryption is not the problem here!

Just accept your device is bricked and bootloader locked.

you previously had enabled and authorized usb-debugging, so keep your RSA key somewhere safe (adbkey.pub) as adb is your only hope!

you can try (HOME_CSC or heimdall)

- flash stock ROM A405FNXXU3ATA4

- flash combination ROM

if you can't get adb access that way

or fix boot-loop, consider your data is lost.

now last there is one more try...

- flash more recent version of stock ROM

(keep in mind this will upgrade encryption keys, so even if you could roll-back to lower bootloader version, your encryption keys are rollback protected)
[General Questions and Answers] kerstin92:
Hi alecxs,

could you explain why read access requires write access? Aren't there partitions (such as /system) which are read-only? Linux does distinguish between read, write, and execution permissions:

File permissions and attributes - ArchWiki

wiki.archlinux.org

My system crashed the moment some apps were uninstalled by pm uninstall, so unless the file system was corrupted, the data should be physically intact. And unless the entire /data partition is encrypted as a unit, modifications to a single file should not render the entire partition corrupt - at least this is my assumption concerning file-based encryption (FBE). Or maybe I misunderstood: Did you mean that FBE is a combination of full-disk encryption (FDE) on top of FBE? I.e. first every single file is encrypted and then the entire disk/partition is encrypted in addition?

By the way, what do you mean by "keeping" adbkey.pub safe? Are you suggesting to copy/dump this file? How?
[General Questions and Answers] alecxs:
how do you want to alter userdata? you only can flash partitions, that's it. so without reading the partition off device first, you have no partition image which you can later modify and therefore you have nothing you can write back on device, right? so this should be the first step, not second - find a way to modify userdata content - "write access" (not to mix up with linux file permissions which is unrelated to "writing" flash memory or "flip bits" as you said)

I have checked TWRP it seems your device does not use samsung flash friendly file system f2fs but regular ext4 journaling file system. so it should be possible to mount disk image and delete files (assuming you managed to dump userdata.img off the device - which I don't know how you wanna do that, as asked above). there exist also combination variant of FDE + FBE = "metadata encryption" but I don't think samsung uses that. I have seen samsung devices with android 10 still running with FDE, so please check your encryption type yourself.

[General Questions and Answers] kerstin92:
Sorry, but you're not making any sense to me. Read access is read access, write access is write access. You don't necessarily need write access in order to read out data - or do you, on a transistor level? Are you implying that ROMs actually provide write access for readout operations?

Example:

-rw-r--r-- => Read & Write access

-r--r--r-- => Read only

Why would you need write access in order to read a -r--r--r-- file?

...which is totally fine, because I don't necessarily need the clear text file name, just the memory range that the file occupies. Then e.g. write zeroes to it or whatever is necessary in order to make Android consider it as deleted (or sufficiently corrupted) and restore the stock version.

Neither is it necessary to decrypt the file content as I'm not interested in its content - the goal is to delete the file as a whole.
[General Questions and Answers] kerstin92:
Edit: Wait, are you trying to tell me that delete operation = write operation?
[General Questions and Answers] alecxs:
what ever you meant with "Write access comes next" you are confusing yourself when mixing up with linux file permissions - I never said that. I am asking about "write zeroes" - how are linux file permissions relevant here?
[General Questions and Answers] kerstin92:
I was assuming that Android uses a similar file system (ext4?) as Linux and therefore file permissions work in the same way...
[General Questions and Answers] alecxs:
yes file permissions work same way on ext4 file system - lets call it upper layer (file system layer)

identifying and flipping bit on given offset on eMMC Flash Memory is raw access - lets name it physical layer (low layer)

there is also yet another middle layer (FTL Flash transition layer) in between to translate NAND flash file system into linux file system, which is completely managed from eMMC firmware/controller, but lets ignore that for now...

so what you want is write access on physical layer, which then (hopefully) affects upper layer. you can safely ignore file system permissions on upper layer as they are not used for this method.

I said write access is the critical step you should care first (no matter what layer)

In current (bricked) state you don't even have read access

By the way: "Wiping the cache partition" refers to wiping the dalvik cache, right? I.e. deleting the ODEX files
[General Questions and Answers] Droidriven:
Depends on whether you have stock recovery or custom recovery. Stock recovery has a "wipe cache partition" option(it might actually include dalvik/ART cache though) and custom recovery has the option to "wipe cache" and "wipe dalvik cache". Typically, when we tell someone to wipe cache, we mean, if you have stock recovery, choose the "wipe cache partition" option in stock recovery, if you have custom recovery(especially after making any kind of changes to any part of the system partition), wipe the cache and dalvik/ART cache.

[Galaxy S6 Edge Q&A, Help & Troubleshooting] dagoston93:
Hi,

It was my first time to install a custom OS to my phone.

I used Odin and TWRP to install Lineage OS 17.1 to my Galaxy S6 edge (SM-G925F).

After installing it successfully, the device reports in the settings that it is an SM-G920F, not an SM G-925F.

Is that normal?

Shall I do something or just live with it?

Can that cause any problems?

I used the TWRP from this link: https://twrp.me/samsung/samsunggalaxys6edge.html

And I downloaded the last release of Lineage OS 17.1 from this link: https://github.com/enesuzun2002/LineageOS-Releases/releases

[General Questions and Answers] PsychoMcSatan:
I've been troubleshooting issues on my Nubia RedMagic 6S Pro by installing various stock rom versions, using the built in system updater. What's weird is that every other install and wipe and subsequent setup asks me for PIN, while the other half of the time it's not needed and allows for offline setup, like it hadn't been setup with a Google account, which it always was. I hadn't at that point ever enabled OEM unlocking either.

I did purchase the phone used so who knows what the previous owner was up to, but how is this possible? Should I be worried?

The issues I'm troubleshooting are restarts that occur in clusters. That is, I could be fine all day, then all of a sudden it'll reboot, then laggy on the unlock screen and reboot again. It'll repeat this maybe 5 to 10 times, sometimes starting up and running okay a minute or two between reboots, but then all of a sudden it'll clear up and be fine again for hours.

I've sent a bunch of logs to Nubia Support and ultimately their response was "Kindly let you know that there is a high probability that it is not a hardware problem, but that you cannot complete some software maintenance by yourself, and require professional tools."

Since downgrading the ROM was Nubia's first suggestion, I've gone up and down ROM versions more than a couple times, usually with full wipes, and reboots occur whether I was asked for a PIN or not. Is there anything I could try before sending it in (out of warranty)?

I did check if this is a sim card problem and I installed this sim card that cannot get active the LTE/VolTE in another cell phone and in that cell phone I was able to actived the LTE/VolTE. So this tell me if not a sim card problem and it is pointing to a device problem.

If this option LTE/VolTE can be active only in one the sim card, then I would like to know how can I make this change to the sim card I want to hace this option. I tried to swap the sim card and did not solve this problem. Please if anyone have any suggestion please let me know. Thanks.
