My s8 is stuck on the "powered by android screen" after following this https://forum.xda-developers.com/galaxy-s8/development/recovery-twrp-galaxy-s8-exynos-t3594902
Is there any way I can reset my s8?
Edit: I have managed to get onto TWRP but get the error "unable to mount"

Do you know how I would fix this?
Nope there where a lot of solutions on YouTube but non of them work. And since you can't access twrp to mount data etc you can't flash the file

Can't flash TWRP on my S5 SM G900F.
-Auto Reboot is unchecked on Odin.
-I've used Odin 3.07/3.09/3.10.
-Reactivation Lock is OFF
-USB debugging is checked.
-I've tried with TWRP (TAR obviously) 3.1 and 3.0.
Am I missing something?

Drivers are installed. I flashed a recovery on a Galaxy S3 not so long ago and everything went fine. That's the reason I posted this thread. I do not know what else to do.
On download mode there are some things like "Download mode secure" "CBS Enabled". It has something to do?
I also have the same problem.. followed every possible guide and no matter if I successfully flash with odin, heimdall or from twrp flash app as root.. when booting my S5 immediately into recovery with volup+home+pwr it will always show the old recovery and not twrp!! Is it readonly and just acting to be flashed or what?? Some carrier might have locked the recovery preventing flashing? It's a SM-G901F klte from swissmobile...
thnks for any answer/suggestion.
Your bootloader is unlocked right?
what do you mean with unlocked?
is there a way to verify it?
and most importantly to unlock it?
Just Uncheck Auto Reboot on Odin
No autoreboot of course i unchecked and do manuale Direct boot to recovery
Anyone knows how to check if the recovery partition is protected
i have the same problem please anyone can help?
I solved it by using a short usb cable, no usb3 ports, only usb2, maybe you try different ones on your laptop/pc, also avoid any hub in between. It's incredibly picky!
Hi, I think I f***** up badly...
I wanted to root my S7 Edge SM-G935F running android 7.0 so I enabled USB debugging and OEM unlock.
I used Odin to flash a CF auto-root I found for the 935F for android 7 and the site just said I had to install SuperSU after that but it was just boot looping.
After that I installed TWRP for my phone and installed the zip with Superuser. I kept receiving the error "failed to mount /data (invalid argument)".
I googled it and found a video that said I had to change my system "file system" from EXT4 to FAT. It was stuck so I rebooted the phone...
Now I can't load TWRP (it's stuck at the loading screen) to do a factory reset and when I do a normal boot it doens't go further than the S7 Edge screen, it doesn't go to the flashing SAMSUNG screen.
Now when I choose to reboot in Odin mode it says "An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software."
I tried to do that but it says "unsupported device" and it doesn't see my phone in the Emergency Software Recovery tab.
I could have done a factory reset before but it's not the first time I root a phone and I never had a problem so I didn't back anything up but I have some very important pictures on my phone for school.
I enabled adoptable storage so I couldn't just take out the 128gb Samsung Pro + micro sd and copy the pictures on my pc.
Can somebody please tell me how to factory reset my S7 Edge even if I lose all my data. Sorry for my English it's my third language.
Thanks in advance
If I can remember correctly the "An error has occurred while updating th......." screen is actually the same as download/odin mode, so you can odin flash back stock rom.
Your data has probably already been lost during file system changing which automatically format /data.
Also I have never seen any phone run on FAT file system. S7 only support EXT4 and F2FS(required custom rom and kernel). So be careful next time.
AFAIK, there's currently no root available on stock nougat touchwiz rom unless you use modified kernel&rom.
For TWRP to be able to read /data.
/Data need to be FORMAT in TWRP once to remove encryption, so that TWRP can read it.

You format data on twrp after install twrp?
You could try to restart to recovery via TWRP and be sure to unplug usb-c cable prior of doing that then try flashing something.
If that's not working you can try the Format data button in the Wipe/Advanced wipe section, afterwards wipe everything, connect the phone to the PC (while in TWRP) and transfer ROM, GApps... via adb push. Try flashing the ROM again, if it's not working again remove the cable and restart recovery - flash again.
I encountered this kind of problem and these techniques seemed to solve it.
it's work thanks!

Thanks so much, man. you guys in this forum rock!
hey to everyone who faced problem like that wont solve with this solutions like wipe data or boot recovery and some type of this things, sometimes the problem isnt that serious and only requires like force restart with volume down+power button and then turn your device power on again and maybe it should work like it did for me (sorry for bad english )
thanks
Hi,
So I rooted this device successfully but with my dumb head I apparently disabled OEM unlock.
Now my device is not booting. It only shows the samsung logo. I can go to download mode and android recovery.
I already tried:
- Wipe data
- Install stock firmware using Odin
- Install TWRP using Odin
None of this worked. It gives errows like "Custom binary blocked by FRP"
How can I possibly turn on the OEM while Im unable to go into Android?

Flash stock rom via fastboot.
And try to reboot to bootloader from twrp it'll put you in fastboot mode.

That's what I told the person to do in short he/she didn't respond.
He/she should update the thread whether he/she got it working by doing something or fixed it via service center. Others just try to help without knowing if it is needed or not.
First of all, i want to say i'm sorry to all of you.. especially for those who tried to help me by replying my thread. I'm sorry for being silent and not updating on you guys. I managed to figure it out the next day after i posted this thread before any of you replied and just kinda forget this thread- which is a bad thing to do. I'm sorry guys. I won't do that ever again.
With that out of the way, i'm going to answer all of your replies

I tried that, it didn't work. Either reboot to system or bootloader, it just went back to TWRP.. with the "Keep System Read Only?" thing.. acting like i just installed TWRP for the first time. Even when i chose to turn off the device, it came back to TWRP.

Didn't try that one, because as i said i've figured it out the next morning.

Again, sorry for that
Here's what i did to fix the issue :
1. After some more searching in the next morning (literally the next morning, few minutes before i gone to school), i stumbled to this thread post : https://forum.xda-developers.com/showthread.php?t=2522426
it says that if you "Put the phone under a strong light and longpress power and volume down, your phone will reboot in bootloader.".
So i tried that. I hold my phone right in front of my monitor, then hold the power and volume up to get into fastboot mode. And Voila, it worked. I get into fastboot without any problem whatsoever.
Somebody else also replied "Just hold the power and volume down for a long time and hold it in front of a bright light, something about the proximity sensor."
So.. yeah. Didn't really know how it worked out, but it worked. :silly:
2. After that, i just installed a different version of TWRP (This one specifically https://dl.wafuu.id/twrp/X00T/twrp-3.2.3-0-X00T-20181214.img which i got from someone in the telegram group) and just redo the HavocOS installing process. It went smooth, and i manage to boot the system without any problem.
Problem solved. Just like that. However, i think i know what was causing the issue.
When i was trying to install the GApps (before stuck in bootloop), i only managed to get to the part when i had to choose to either save my choices or not. After that it just went back to TWRP. I didn't know that it wasn't actually installed yet, because i thought it was installed already. Yep, that was my first time installing GApps and i actually never seen the entire installing process. The way i know that is when i installed it after the fix (after i installed a different TWRP) and then saw the "installing things" part. Silly me.
So i think that was the issue. It was because i used an older version of TWRP which i got from this thread https://forum.xda-developers.com/asus-zenfone-max-pro-m1/development/recovery-twrp-3-2-1-x-t3787134 . Maybe GApps didn't support that version. I knew it was an old version of TWRP. Why i was using that version and not the latest one? Because when i tried to install the latest one from this thread https://forum.xda-developers.com/as...ent/recovery-unofficial-twrp-3-2-3-0-t3888110 , it didn't work on my phone. It fails to detect my internal memory (0mb).
I think that's all i can say. Again, i'm sorry to all you guys for the late respond. Thank you for replying my thread and trying to help me. I hope this thread will eventually help someone who faced a similar problem to mine.
*Last but not least, Shout out to Dyruz from the telegram group who provided me the working TWRP and tried to help me as best as he can. I would've not fix the issue this because of him. Cheers!
