Experiences with rooted and encrypted S7 - Samsung Galaxy S7 Questions and Answers

Since almost one week i am trying to a S7 rooted, debloated and encrypted.
Starting encryption with a decrypted phone from CFW:
After installing a CFW on an decrypted, i were not able with two different CFWs to get it encrypted. If you select the encryption by AndroidMeni the process starts and after a few minutes, it does a usual reboot without any changes. I tried this method, and this as well. Some xda users told me, that i have to use stock. I had no chance to get it encrypted afterwards with selection through Android/Security menu.
Start with encrypted stock rom:
So i gave up and descided to start with stock (oct release) and encrypted.
Flashing Stock with Odin, let it reboot and let it encrypt on first start, go through the assistent, reboot to download mode and root with odin and cf-auto-root.
Dont have to install TWRP, hence doesnt make any sense. You dont get acces to /data nor to /sdcard (internal storage).
After that i tried several debloating scripts, some worked, some not. So i decided to debloat manually with SSHdroid & putty.
Then i recognized, that the apps were not removed, although the files were been deleted?!
I did a factory reset, now the phone was clean. But the encryption was gone
btw: my experiences with FlashFire were also negative. Somehow it doenst let FlashFire mount any partitions on restart. It just doenst work.
Do anyone have an idea, how can I use this damn S7 rooted, debloated and encrypted? I can live with stock too.
I lost my interest - just tired, wasted so many days. Just want to make my data on my phone safe against a thieve.
Thanks

OTA update Fail, Save my data

Hi ~
- Be kind with me, it's my first post! -
I'm facing a very bad problem with my Galaxy S6. A week ago I received an OTA from Samsung and I installed it. My phone rebooted and showed the bugdroid, meaning that the update was progressing. After that, the device keep rebooting over and over just after I entered my encryption password. I said to myself that I can try to wipe the cache because maybe an application was causing this problem. But now, the device is only showing the Samsung logo then just shut himself off.
Now I need your help to get my data. The hard part is that my device is encrypted. After many hour of search I see two solutions:
Flash the rom via ODIN
Install TWRP which can read encrypted volumes
The first solution seems easy and I keep the warranty. The problem is that I'm not 100% sure that flashing the rom again will not touch the /data and /sdext partitions (and the header/footer where master key are to decrypt the volume).
The second solution seems safer and should not touch any other partitions. But knox counter will be incremented and I will loose my warranty.
So, does anyone could test if flashing the rom via ODIN do not absolutely touch encrypted volumes and certificate that I will be able to get my data again?
Thank you a lot
Have a leap of faith. Go ahead and flash. Otherwise bring it to Samsung for warranty repair. They may be able to recover your data for you.

I want to be sure and I don't want to loose any photos if possible, so no
I already tried to go in a Samsung repair store (Allo PSM), but they just don't care about my data, their job is just to make the phone working again.
So Anyone is able to confirm to me that flashing stock Galaxy S6 ROM (AP Via Odin) doesn't touch the /data and /sdext partition that are encrypted?
After many hours of search, I was able to make my phone working again!
For anyone concerned by the problem in the future, here's some informations:
You can flash a stock rom, your encrypted /data will not be erased and you will be prompt to enter your password on the next boot
In my case flashing a newer rom didn't solve my problem (bootloop after entering the password of the encrypted partition). I had to flash the rom that was in the phone before the OTA.
Now everything seems to working again. No data were lost, all my configuration was saved. Android showed a message that a problem occurred during the upgrade process and I sent logs to Samsung, hoping that it will help them!

Need help on how to flash TWRP properly (Exynos) (SM-G930F)

Hi there. Recently (just yesterday) I tried flashing TWRP 3.1.0-0-herolte via Odin V3.12.3.0. However I ran into a little issue. Bootloop. TWRP seemed to work fine, but the phone wouldn't boot into android (stock touchwiz), exhibiting the 'samsung galaxy S7' logo periodically, but not going past that. Firstly I'll give some details on the phone and how I 'tried' to to flash TWRP. The phone I have is an Exynos variant SM-G930F running Android 7.0 and the recent update from late March. It is an Australian model (otherwise known as the 'international' version I think). Anyway as for what I was using as a guide, it was this. Before attempting this I enabled 'OEM unlocking' within the developer options but not 'USB debugging' (not sure if this contributed to the issue, but thought I'd mention it anyway). Later on I downloaded the Samsung Mobile Drivers and the tar file for TWRP. Installed the drivers, opened up Odin, entered download mode on the S7. I placed the tar file in AP and connected via micro usb. Almost everything, including auto-reboot, was turned off except F. Reset Time. Though chances are I probably left it on because I'm a doofus. After all that I pressed 'start' without doing any button combinations. Then after the screen went blank I pressed volume up + home hey + power button, roughly all at the same time. And then I entered TWRP. I then swiped to 'allow system modifications'. However as I didn't want to root the phone at the time, I decided to power it off through the menu. The next time I pushed the power button however, it was stuck in a bootloop. I then went back into TWRP and noticed that when I went into the install menu and was looking at the internal storage it appeared as 0mb (I thought that twrp had deleted all my files at the time), and I couldn't access the files I normally do like the downloads folder or app folders. However it seemed like most of the system folders were there like 'root' and 'data' etc. I then formatted the data and then did a factory reset as I thought it might fix the problem but it didn't. I swiped to install the twrp app but unchecked the two boxes. I then did some research and found out that if I ever were to run into an issue like this that I should flash the stock firmware, which is what I did. And viola! It worked again! I was slightly stressed at the time, lol. Luckily the apps and data I had previously were stored in the cloud.
After all this I have a question, what do you guys think I did wrong? Have you ran into this issue before? And what do you think may have caused the bootloop. I eventually want to start rooting my S7 and perhaps flash a rom, but I don't want to run into the issue again. Cheers!
P.S. I'm probably the biggest tech noob I know so go into a little bit of detail if you know what I did wrong so I don't make the same mistake again
Sounds like you hit the problem listed in step 9 & 10.
At this point, you will reach the screen asking you if you want to allow system modifications.
By swiping right, you will trigger dm-verity, and if you don't follow the next step you will be unable to boot

You swiped to allow system modifications, but you chose not to root and turned it off.
I don't see any mention of you flashing the dm-verity and force encryption disabler zip in TWRP which is required even if you're not rooting.

Hm, that might actually be it. As a question how would be able to do that? Do I need to download that separately or something ( the dm-verity and encryption disabler zip I mean)?
EDIT
Actually never mind, it seems to say it right within the guide lol. So the problem should go away if I do that first yeah?
Yep just download it and put it on an SD card or transfer to the phones internal storage (I think TWRP lets you USB transfer) and go install zip in TWRP and select it.
That should stop your boot issues after installing TWRP, should even work even if you do it after a failed boot.

Hey bro, just wanted to say thanks. Got it rooted soon after as well. I found out I had to format data first before because it wouldn't let me install any zips. But after doing that it worked without any hiccups.
Cheers.
You should reset/wipe ur device after you have installed twrp through odin. That's a simple that some people wouldn't see in the tutorial. Then if you want root access you can flash SuperSu. Hope your problem will be solved. Good luck.

Glad it's all working.
First time I installed TWRP I installed a ROM straight after which said to to format data, so never knew TWRP install alone needed the format data too.

From what I understand that's because the ldm-verity triggers. And so formating the data removes any encryption allowing for things to be flashed. But because I didn't do all of that first my S7 wouldn't boot up past flashing twrp.

oneplus6 seems damaged following a failed twrp restore

So here is situation.
Phone been running 8.x version of havocos for months, however I was never fully happy due to broken usb tethering and random lockups (blue light freeze).
I decided to work on the phone 2-3 days ago, this involved doing a manual backup of all of data/media, and a nandroid backup. As well as some exports of configs in tasker etc.
I then flashed OOS stock, and nolimits, discovered tethering was still broken (yet it works with same sim in samsung galaxy s7 and hauwei).
This was the only issue tho, everything else was functioning as expected, phone was still fast.
Then I needed quick access to something that was on my phone from havocos, so decided to do a nandroid restore, this nandroid backup had all partitions ticked. The restore I also had all ticked.
The restore failed with an error 255 during data restore, I googled and found out is a nasty known bug for 2 years on TWRP, this backup was done on 3.2.3, I know now is a newer 3.3.x where this particular bug with corrupt backups might possibly be fixed.
I decided to try and boot havoc anyway but it boot looped, so I then went back into TWRP, and restored the vendor partition which was skipped. As it stopped on data, still boot looped, but also now this created a device is corrupt error on every rom boot even on stock OOS.
I spent ages trying to fix this error and during the process, discovered my phone no longer can be detected in flash boot as a com device in windows so currently the phone cannot be used with the MSM tool.
Eventually I reflashed stock using a flash-all script from here, and also put back on twrp using that script, and noticed even more issues that were not there before.
1 - phone is now much slower, stock before booted in one second after first boot, now its way way slower. Over 10 seconds so 10x as slow.
2 - I think before was a cache partition but is now gone. Supposedly these arent a thing anymore tho.
3 - nolimits zip will no longer flash with an error 1, I did exact same process as before but simply doesnt work now, the twrp detailed log right before the error 1 says "Please install the latest Magisk!" which suggests its failing to detect magisk.
4 - camera app is way slower, and OOS feels slower, laggier in general than before the problem.
5 - MTP no longer works when phone is booted up, again this is stock OOS and even if phone isnt rooted no magisk etc. But still works in TWRP. Basically the device pops up, I can see internal storage, but the size information is missing, and is no visible files/folders.
From what I can see I think my EFS is fine, I see an imei number.
I did fix the corrupted device error using a reboot command someone posted in that thread, so that error is gone now at least.
Try to flash oxygen os beta version from the official download links, let it install the stock recovery, then boot into rom, finish the installation progress by just skipping it and then factory reset it twice from recovery mode.
after doing that and finishing the setup , try to take picture and see if its saves it to gallery ( if the picture delete it self try to factory reset it through recovery for 1 more time)
I think you have figured out whats wrong, it just clicked, and I went to post and found your post so sorry no reply yet.
Indeed the problem seems to be a lack of /data/media/0
I have multiple times wiped data, and twrp has been putting files directly in /data/media, I just discovered I Cannot even take screenshots, magisk cannot download modules as well.
So I guess the stock recovery creates this structure?
Pretty shocking that twrp doesnt fix this or even have an option to. I will report back and let you know how things go, thanks.
Issue still there after stock recovery reset, wow these phones are damn hard to work with.
Also it seemed to do nothing, no settings were lost etc.
So basically stock recovery even if I choose full wipe does nothing, there seems to be some kind of lock on the internal storage that anything made by one plus is refusing to write.
I wonder if this is due to the device is corrupt message I had before where it said the device can no longer be trusted.
I can confirm that files that are on there are now visible in file manager and root explorer. But file manager can do no writes. root explorer can create new stuff but cannot delete or overwrite anything there, gets access denied.
I propose to start over again following this guide, option flash-all-partitions.bat. Helped for me.
I already stated thats already been done.
I eventually got msm working. and that luckily worked.
@chrcol ..., but you've issues

In recovery, format data. Problem fixed. Wipe will never fix your problem but format will.

Verity activated / "Verification failed" - Can /data be recovered?

Well, I just did something bad. I have a new Exynos-based S7 (SM-G930W8), which I unlocked, rooted, and installed LOS on. So far, so good.
I then proceeded to root my old S7 (same model), ironically to make it easier to transfer over the application data... Things went so smoothly on the first device I did not take the time to make a backup (so I did not realize that TWRP is not able to mount the /data partition).
I rebooted to Download mode, flashed TWRP twrp-3.5.0_9-0-herolte using Odin 3.13, and rebooted to Recovery. I then followed the same steps I took with the other device (Install of no-verity-opt-encrypt-6.1, and Magisk-v21.4). After rebooting I am greeted by the "Verification failed" / please delete all your personal data screen.
Now, I have made a backup of the /data partition using adb-pull, which of course will be useless if the encryption scheme cannot be restored, or something. I assume the contents are irretrievable, but I'm having difficulty finding solid answers on this since most posts are from people who switching ROMs (and so expected to wipe) or were smart enough to back up before proceeding.
It would be amazing if the original ROM could just be flashed through Odin (including the HOME_CSC archive) and the phone would just pick up where it left off... Or if I could use the fastboot oem disable_dm_verity commands, or just wipe the phone completely, restore to stock, and then restore the previous /data once it's up and running. Again I'm expecting none of this is possible, but I would be really grateful if someone who has some experience with this could chime in. Just going to sit on my hands for now in case further messing around with the phone makes recovery even less likely to succeed.

[Poco F2 Pro][V12.5.5.0.RJKEUXM] Stuck on Boot Loop

Hello there, I need help :/
My Poco F2 Pro is stuck on a Boot loop, without any obvious reason.
The device became really laggy and painfully slow. Because of that, I wanted to restart it. But now it is stuck in a boot loop
I rooted the device using Magisk Canary 1 week ago. Yesterday, I installed the custom recovery "TWRP".
And with Titanium backup I froze a few system apps... which didn't seem to be so important (I googled them beforehand)
Today, I tinkered a little bit with AF+wall (which still doesn't really work), but except of this, nothing else.
I tried (using TWRP) to wipe the Data and Cache, but it fails "unable to mount /data/media/TWRP/.twrps
Also tried to change file system to ext2 and then back to ext4, but it again says "unable to mount"
What can I do now, resp. how can I get my device? I made a backup using Titanium, but it still is in the internal storage xD
OK.. I will give up the backup, I have all the important files backed up earlier anyways...
My plan is now to use MiFlash to flash the newest MIUI version [V13.0.2.0.SJKEUXM] onto my device.
Only fear is.. I have TWRP installed, and as far as I know, it does not support android 12... what will happen if I do this nervertheless?
And I want to get rid off TWRP nevertheless, so it would be perfect if it just gets replaced with the stock recovery...
sounds like a plan. still any question?
Nope, thank you, everything worked out as planned
