Phone broken because of TWRP change file system - Samsung Galaxy S7 Questions and Answers

I used a video on youtube to install TWRP on my galaxy s7 (SM-G930F)
Almost everything worked fine, except I was not able to make a backup. I got the error "Unable to Mount /data". A lot of videos told me that I need to 1. wipe 2. advanced 3. change filesystem 4..exFat and then EXT4. I tried this method, but TWRP froze after some time during the exFAT change process. Now my phone tries to boot into recovery mode, but won't go further than the very first screen of TWRP (where you see the version number and the logo).
What should I do now? I tried to reflash TWRP, but it still doesn't go past the very first screen. I am also not able to turn off my phone, because it keeps rebooting into recovery mode. I think that I need to find a way to change my filesystem to EXT4, but I cant do that with TWRP.
Can somebody help me plz (and sorry for my bad English)

press vol down + home button + power button to boot into download mode and reflash stock rom.
download rom from here https://www.sammobile.com/firmwares/

I just tried this, but it does not work.
Odin says that thread has successfully flashed all the files. My phone is installing the software update and erasing, but after that the screen is black. I cant boot the device or even enter recovery mode (download mode still work). I tried both flashing CSC and HOME_CSC, but both didnt work.
What should I do now?

The same thing happened to me. Keep trying to access the TWRP even if it takes a bit longer than an hour it will enter. You do not have to do anything else, just keep trying, when you access, you'll be able to repair the partitions, change them to fat32 instead of exfat, and then return to EXT4. It will work.

Had a feeling that this would work, but really didn't had the time to wait. Have wasted €20 to fix it, but still thanks for the reply (even if you are a few months late )
Hope this will help out other people who have the same problem

Loading stuck on logo

hello everyone,
i've got a big problem. my samsung galaxy s1 gt-i9003 stucks at logo screen. i flashed many roms, wiped everything, still got the problem. don;t know what to do. can someone please help me? before i got this problem, i used firmware only by kies.
Well, try booting into download mode: hold power + volume down.
Then download odin and use that program to flash a stock rom to your phone. The problem is most likely that you did not wipe correctly.

Okay, then you need to give me more details, like whether you rooted your phone or have CWM Recovery installed. What ROMs did you flash and how you flashed them. Give me anything that might be relevant and I may be able to help.

i downloaded firmwares from samfirmware,com. i just downloaded firmwares for i9003. how i flashed? well i wiped data/factory, then i just opened odin, puted all files (pit, pda, phone, etc.) and checked the repartition box. btw, after the install is completed, the phone reboots and i get this error:
Code:
E: format_volume: rfs format failed on /dev/block/mmcblk0p3 Data wipe failed
when i try to wipe it, i get this error:
Code:
Can't mount /data
And there is more: those 2 buttons (back and menu) are switched off
PS: sorry for my bad english
Yikes, you *MAY* have soft-bricked your phone. It seems that internal memory might have been corrupted.
Take a look at this post, this guy had the same problem and several solutions are listed:

Honor 8 Can't Download Firmware, Can't Flash, Bricked? [Solved]

Hi, after trying unlock my bootloader, I couldn't get into recovery mode without "Your phone cannot be trusted" getting stuck on my screen.
I re-locked the boot loader but now when I go into recovery it says "Data Partition is corrupted please format" then it asks me to connect to a wifi network which then just shows errors everytime the password comes up.
I tried to turn on USB Debugging to ADB sideload a firmware, but I can't because the phone has been resetted; if I try to enter a wifi password the keyboard doesnt show it's just the google voice (which doesn't work) with no options. If i skip the wifi option it just goes on the google login and gets stuck on "Checking Info".
Any solutions to the problem please?
EDIT: I just re-unlocked the bootloader and now its permanently stuck on "Your device cannot be trusted, booting now" regardless of what buttons I press during startup
EDIT 2: I fixed it, it was long and complicated but I got it to work, here's how.
1. When flashing TWRP, I realized I was flashing the TWRP for EMUI 4, so I flashed TWRP for EMUI 5. (Make sure Bootloader is unlocked)
First have all the adb/fastboot drivers, for windows shift + right click the folder and click "Open Command here"
Make sure the twrp img file is in the same folder as the adb folder.
On the honor 8 phone, if it is stuck like mine, turn the phone off and then hold Volume Down + Power Button until the download mode is on the screen
Type "fastboot flash recovery (twrpfilename).img"
Once it's done, turn it off and then hold power button + volume up AND volume down at once till TWRP comes on
(Continuously hold it, if the "Your Device cannot be trusted" screen comes on release)
2. (Make sure internal storage and data are backed up externally for this)
Reset system, data, cache/dalvik, and internal storage
3. Download Update.zip and the second .zip from a website on google, search Honor 8 Manual Nougat and click the link from smartstocknews (I can't post links) but do not follow the steps from that website, and also download GAPPS from open GAPPS. Make sure ARM64 is selected and not ARM as well as 7.0
4. After wiping, mount the Honor 8 by connecting it via USB to a computer, and press "Mount" on TWRP
Upload the both update.zip and update_data_full_hw_eu.zip and GAPPS ARM64 7.0 to internal or external storage
5. Exit mount and go to install, install the zips in this specific order and do not reboot in between
A) Update.zip
B) Update_data_full_hw_eu.zip
C) GAPPS.zip
6. Reboot after GAPPS is done (it might show already installed, if that's the case then it's alright, reboot anyways)
Download the 70mb package for firmware downgrade and the latest marshmallow firmware from your regional huawei's website.
Extract the small package and put the .app file in a folder called dload on the SD card and insert it in your phone.
Boot by holding volume + volume - and pressing power, holding all 3 buttons until the phone vibrates.
The package will flash and afterwards you repeat the process, this time using an .app file from the full marshmallow firmware.
The 70mb package installs not matter how messed up your file system is, and makes your phone ready for the MM firmware. This process brings any brick back to life. Good luck.
I too was trying to root my FRD-L04 and apparently used the wrong TWRP because now I get...
Code:
Unable to open ' ' to wipe crypto key
Unable to wipe Data
Unable to format to remove encryption
Failed to mount /data (invalid argument)
and I cant get the keyboard loaded so I can log into my wifi when I do a factory reset. I really have no idea how best to attack this...my phone is bricked I can get into TWRP 3.0.2.0 recovery, sideload, and fastboot (i think). I am currently downloading the stock ROM for my device and will try to sideload it.
I feel I need to fix the data issues thought before trying to load the ROM as I dont think my data partition is working at all now. Does anyone have any suggestions or a step-by-step guide on how to fix my bricked phone?
I've tried all sort of things today but no matter what, I cant get a keyboard working so I guess that means I'm screwed....
EDIT - my phone doesnt have a insertable SD card so I cant fix things the way the above poster suggests.

This is truly one of the worse phones I have ever had when it comes to root and such. My frustration over what, for a unbranded unlocked phone that *should* probably SHIP with root, this phone has and is putting me through is super high.
That being said...so I flashed the new 3.1.0.0 recovery. Before doing that, I had just tried to Unbrick the phone with flashing B162 image with 3.0.3.0...so now the phone is totally frozen in the "Your device has been unlocked and can't be trusted..." screen. Nothing I seem to do can get it out of this mode.
I want to install the rooted b378 boot.img file I just downloaded, but am unable to find the button commands to get the bootloader loaded. Does anyone have any suggestions in somehow trying to save the day with this damned phone?
much thanks in advance.
EDIT: So I got the phone in bootloader mode by pressing vol up/vol down/power and inserting the usb cable...i flashed the rooted boot.img and twrp 3.1.0.1 to both recovery and recovery2 and now i can get into recovery. I feel like I may actually have a chance now to fix this damn thing...
So can anyone point me in a direction where, from this point with the new recovery loaded and the modded boot image installed, where i can get this phone working?? ill use ANY ROM it dont really matter at this point...
Don't worry. It's really easy, once you know what to do, just realy easy to screw up if you don't. If your phone is a mess just roll back to android 6 using the procedure i described above. Once your phone works, update to nougat and install twrp and root following this guide: https://forum.xda-developers.com/honor-8/development/twrp-t3566563

I pretty much have the same issue. No keyboard showing, just the stupid voice thing, and the Bootloader is Relocked. How did you get it fully unlocked. I can't get it. I guess let me get that resolved first (the bootloader) and I can try to go from there. Please help me.
UPDATE: Never mind I fixed it. I'm not really for sure how either but I think it mainly was just persistence.
Didn't work
Hello, so earlier today I tried to install RROS newest version in hope to get magisk/unrooting my phone because I'm addicted to snapchat and I rooted my phone with SuperSU earlier but didn't know u can't login to snapchat after that. It failed idk why, (I followed instructions very clearly and searched info from internet before doing that) causing me to brick my phone so when I booted it, it only showed black screen. After couple hours not finding way to get into twrp with my circumstances I managed to flash boot, recovery and system images, I tried to reboot and see what happens, (just in case, I kinda knew I didn't had ROM installed at the time, I also was hoping RROS to boot) nothing happened expect my phone got stuck in boot screen for booting EMUI, which was not installed obviously. Again after couple hours I stumbled to your post and managed to finally get myself into TWRP, I followed again ur instructions and everything was going fine, no erros, not anything. When Gapps was finished installing, I rebooted and again it just got stuck into booting screen. I did press and hold Power button, vol+, vol- and got myself into some kind of ROM installing screen, (hard to explain I don't exactly know what is name of it) and no it wasn't Huawei erecovery screen (Power button & Vol+ and no it didn't work me either saying that "getting package info failed") so in that ROM installing screen it just was stuck at 5% installing, and now I don't know what to do. My phone got locked again and I'm stuck at booting screen.
Note:
I don't have SD Card, should I get one and install stock rom?
Sorry for being kinda unclear but I'm tired it was 7 hours ago I got my phone bricked and have surfed on the web finding for answers ever since.
Also as you might notice, yes, I'm new to modding devices etc but still I'm not totally noob. Please help ASAP.
[SOLVED] So after hour of watching netflix as depressed teen I tried to reboot my phone again just in case, got stuck in booting screen. Then I held Power Button + Vol+ and got myself into EMUI stock recovery mode, I chose wipe cache partition and wipe data/factory reset, after that I rebooted my phone, it was stuck in booting screen for like 2 minutes but then it actually finished booting and now my phone is again functioning and god bless locked & unrooted.

Bootloop in my S8 Plus, where to download Stock Firmware?

Hi,
I have S8 Plus SM-G955F in Germany.
Dont knwo what exactly happend, but my phone was just still running fine (bootloader is unlocked) and I rebooted but then was stuck at "Installing system updates" screen which appear before getting into recovery. However, it does not enter into recovery and reboots after few seconds into "installing updates" mode which then fails.
It does not boot up into Android.
All I can access to is Download Mode.
I flashed "BL_G955FXXU1AQF7_CL11544126_QB13847503_REV00_user_low_ship.tar" Bootloader and rebooted and now it is stuck in Samsung boot logo. If I press Vol up + Bixpy Button + Power nothing happends, it does not even start to load Recovery mode.
I now downloaded following stock firmware through SamFirm: "SM-G955F_1_20171214140840_hlcm4r582t_fac.zip.enc4" (3332 MB)
but when trying to flash it in odin I get FAILED !!! Also if I try to flash TWRP recovery "twrp-3.1.0-1-dream2lte.img" I get FAILED in Odin I now also tried to flash "AP_G955FXXU1AQH3_CL12050265_QB14545623_REV00" firmware using this tutorial: https://www.youtube.com/watch?v=2y0ZZxcNVnE which also FAILED. I think I am completely bricked !!
Please help, phone is completeley useless now
Thanks!

I had the same problem with downloading stock firmware. My problem was that I couldn't download from SamMobile because of server maintenance. So I downloaded from here. An with this tool there's the option to decrypt the file automatically. I forgot to tick this option and had a .enc4-file like you have there. The problem could decrypt this file and then I could unzip it and use it with odin.
So that's your problem: you are trying to use an encrypted file. But you have to use an decrypted file.

Hi,
thank you! But its actually not my problem. Samfirm decrypted and I got the zip with the BL, AP, CSC, CP files in it. But ODIN fails everytime anyway and I have no idea what I could still do now.

Usual behaviour was this: Vol up, bixpy and Power -> Recovery mode which fist starts with "Installing update..." then failed and then it goes into some black recovery mode where you can choose Apply update.zip etc. right? However, in my case this black screen with more commands did not show up, before it was rebooting again by itself.
Now I cannot even get into this "installing updates" mode before recovery, because "Vol up, bixpy and Power" does not bring any action.
Vol down, Bixpy and Power still works and brings me to Download Mode. But it doesnt help me, because once I tr to flash any firmware in Download Mode, it FAILS in Odin, so I am completely stuck, hope you understand

Download mode is the only mode you need for restoring stock firmware.
Try this guide. (Spoiler "Flashing Standard Firmware:")
Yesterday I did it with this one too and it worked flawlessly. But I used Odin v3.12.3 not as said in the guide V3.12.7.

it automatically loaded into recovery before, I was not able to boot into Android, it loaded recovery (but without black screen with more commands) automatically by default and rebooted, loaded recovery again and rebooted, loaded recovery againd and rebooted etc...all I could to to interrupt this was loading download mode.
However, thanks for the link, but it does describe what I did already. And yes, I also used Odin 3.12.3 already because in the video tutorial I linked some posts before they said also, I need to use that version.
However, it simply does not work. Odin FAILS everytime
I am not doing anything wrong, I am sure. The only thing could be that the Firmware I downloaded is still wrong, even I cannot imagine this.

Yes that's the only thing that comes on my mind too if you think everything else is right. Download another firmware file maybe from a different provider than SamMobile.
Or try using different USB-Port, USB-Cable and/or different PC.

Did already, did not help. I think maybe there is something realldy bricked, so flashing stock firmware wont be possible at all anymore?! Is this possible somehow?
btw: Just managed to load into TWRP, randomly it does load twrp, dont know how, because if I press the keys for loading into recovery, it actually does not do anything, but currently I see twrp.
Is see anything I can try from there? btw: formated data (incl. internal storage) earlier already, but it did not change anything.
But any idea what I can try to flash from TWRP maybe? Is there a way to flash stock firmware from TWRP somehow?
I found a backup in twrp, I am currently trying to restore it...

Google found this. But I don't know if this works. I only flashed custom ROMs via TWRP. Stock ROMs always via Odin.

I just ran into this thread: https://forum.xda-developers.com/galaxy-s8/help/stuck-bootloop-flashing-aqg5-fix-t3636857
It looks like you're not the only one...
You know, you might want to try and remove the more current apps you installed and see if that is causing the loop, and if that does not work, just dirty flash over what you have. For me, a lot of time a dirty flash will solve the issue, as it overwrites the OEM software, and in that manner, takes my phone OS back to normal/new state, while leaving my data.

J4 plus (J415GB) bricked

Is there anyone here facing same with my situation? today i bricked my J4 plus, Dunno if its hard bricked or soft brick, I can't enter to download mode and system restore anymore. Im just trying to get oreo back because i fell little laggy on my current os (pie). I went to samsung service center and they told to use JTAG to get it fix but its too expensive for me to pay hundreds buck for this.
Thank you
its not bricked. your battery is full drained. i had the same problem and how i fixed!!! i presed all 3 buttons and put usb cable to my pc and my phone. it goes like bootloop starts and shuts. you will wait with pressed buttons from 5 to 10 mins depend how low is your battery. and finaly will go to download mode and you can flash it then!!!
Bricked my J4+
Can someone help me with a bricked J4+?
I wanted to install TWRP, I followed the guide to the letter on how to install TWRP.
After successfully flashing TWRP 3.2.3-0 and flashing RMM bypass zip (without booting to the OS) I also performed a Wipe Cache in TWRP.
I booted to the Samsung OS and the system overall felt laggy.
I performed a Factory Reset, still the system felt laggy.
I decided to use Odin and install the Samsung factory system (thus go back to Samsung OS).
I booted successfully and decided to give TWRP 3.2.3-0 another chance.
Odin resulted in FAIL when trying to flash with the following error: Can't open the specified file (line: 1892)
I tried different versions of Odin (from last to previous ones), different USB ports, I even tried another PC but no success.
I performed another factory reset and now the phone is hard bricked I guess because it will power on...try to get in stock recovery and Erase...and then power off. I can't get to download mode or stock recovery.
Any help I would highly appreciate it.
Thanks.

you didnt follow guide from letter to letter. is obviuosly you didnt do all you need to do. if you in pie update you need to flash twrp (you did) then NEED to format data(go to wipe choose format data(not wipe data,cache) write yes and swipe to format data.this step is important.then go to recovery again and flash pie patched boot.img and oreo enforcing.zip,then RMM bypass,and then you can do boot up your device.thanks.

The part where I had to format the data...I have missed that. Thanks for pointing it out.
I took the phone to a repair shop because it is hard bricked and it needs jtag to unbrick it.
As soon as I have it back I will try again to install TWRP.
Thanks for the help, I appreciate it.

This is a phone from work and I did toggle EOM unlock and USB debugging in order to flash TWRP.
I did not enter any password, face unlock, pattern or sign in to google....nothing of the sort. As soon as I opened the phone from the box tried to install TWRP knowing it will erase everything after TWRP installation. I really hate Samsung UI and wanted to try Lineage OS or another custom ROM which is not laggy like ONE UI.
After installing TWRP the phone became very laggy (obviously I did not perform a format data...my bad) I did use Odin and flashed the corresponding firmware of the phone and it did that successfully.
I tried to give TWRP another shot by flashing it again but I was getting a FAIL in Odin with the following error: Can't open the specified file (line: 1892)
After this I tried to flash again the same Samsung firmware but kept getting the same FAIL and the same error: Can't open the specified file (line: 1892)
I have tried all versions of Odin but the same FAIL and same error.
Now I can't even get into Download mode or Samsung recovery mode.
I press Volume Up + Volume Down and insert the micro USB cable....the phone takes at least 10 seconds to power up (Samsung logo) and then I see a blue screen with Android robot trying to perform an Erase and then fails and the phone powers off immediately.
As soon as I get the phone I will check your link on XDA and try a GSI ROM.
Which one do you recommend...this is a work phone, all I care about is speed and fluidity and it has to be a daily driver.

yeeeahhh. i am knowing that in hard way. you can check user data only if you have ORIGINAL firmware and not rooted phone(mean twrp),if you have rooted(twrp) then flash with or without user data. some firmwares on web can flash with user data, some cant.anyway as i say you can always ask for help.i will gladly help if i can. good luck.

What you're describing are symptoms of a flat battery and a direct boot to recovery.
To boot to download mode plug in the USB cable first then hold vol up, vol down and power until download mode appears.
There is absolutely no way TWRP caused the lag. TWRP runs in its own minimal OS environment and has no effect on a booted android OS whatsoever.
Lastly your device wasn't hard bricked, a device that powers on even if it doesn't boot is only soft bricked.
Usually recoverable using the right procedure.

I managed to boot into the Revovery and perform a factory reset, now the phone booted normally.
I will try and install TWRP.
When these strange things happened the device had over 80% battery...at least that's what it showed on screen.
Now I see that indeed it was flat 0% and you were right to point out that this is a flat battery problem.
Thanks for the help I really appreciate it.

Yes Thanks. I am at 100% battery. Can I ask a few questions on how to install TWRP?
I am on Android 9.x.x PIE.
Install TWRP and immediately force reboot to recovery.
Flash the RMM bypass.
Format data
Boot to Samsung OS.
Is this procedure correct?
Thanks.

It's correct, but if you want access to the data partition in twrp you need to also install the encryption patch.
You will also need to either install magisk or some other patch that disables dmverity.

Question samsung a536E stuck on bootloop

hello everyone, today i tried to flash twrp on my phone (rooted with magisk and running stock samsung rom), the flash was successful and i was able to boot into twrp but i coudnt access my storage or anything else, so i saw a guide saying to change the filesystem to ext2 then ext4, after i did that i could access most of the other folders but not the storage foldier as it still showed 0mb. i thought i just need to reboot my device to fix the issue but now im stuck on a bootloop. i cant poweroff the device since no button combination is currently working. is there anything i can do to power it off or do i have to wait a few days till the battery drains to 0?
[RECOVERY][UNOFFICIAL] TWRP for Galaxy A53 5G (Exynos)
Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and...
forum.xda-developers.com
this is the link i used to flash twrp except i didnt follow the wipe instructions because i dont want to use a custom os.
and if nothing else works and i have to wait a few days till it drains to 0, will i be able to boot back into samsung's recovery mode or is this device hard bricked?
help will be greatly appreciated.
This phone doesn't have the nice feature of holding the power button for force off so that is a negative here.
I don't think you should have edit:changed the partition types. If that was necessary it would be a ridiculous thing for other Android roms to have to do. Its all Android so should have worked without that.
Its unlikely that anything new will result from a cold boot verses a warm boot. Worth a shot I suppose but don't hold your breath. Expect nothing new.
If its stuck without Odin, fastboot, ADB, all buttons not doing anything, can't ingest and do something from sd card, can't show up via USB on computer, etc with nothing at all then its totally finished since nothing can be done. Consider it a loss and learn from it.
I'd like to also state that there are for some reason people who supposedly bring roms over to devices and they don't have the device so therefore don't really know if it works or not. You have to be careful about the guides you follow. I've seen someone try with a device that could not be unlocked ever for anyone and that person thought it would work. Live and learn.

hello, i was able to boot the phone into twrp and do a factory reset, i had to time the vol up + power button at exactly the time when the screen went black and it worked!. but now i have a question, if i want to get twrp again and i dont plan to flash a custom rom like it says in the guide, how do i get twrp to recognize my storage? and do you flash twrp before installing an os or after because ive done it after installing the os.

yeah so it seems like the issue isnt with changing the file system or anything because i installed twrp again and tried rebooting and i got the same bootloop issue, but if i flash a rom then ill lose twrp like it happened last time so i dont understand what im supposed to do
you have to format data in twrp otherwise it won't see your storage folder.
once formatted reboot to twrp then reboot to system, it should reboot to stock rom and the set up pages.

wipe>format data>type yes>reboot to recovery. i did that and still cant reboot to system bootloop issue persists
yes you did it correctly this time, is there anyway to undo your 'filesystem to ext2 then ext4'?
or maybe you have to flash the custom kernel to get it all up and running again
