Hello everyone,
I bought a phone on eBay (Samsung Galaxy A5 (2016), SM-A510F), but it is locked and the sellor is not responding. I wanna do a hard reset (Factory Reset), so that I can use it again, root the device and install a custom ROM on it (which was my plan all along).
When I boot the phone into Android Recovery mode, I see the option to wipe data/Factory Reset. When I click on that, it says:
-- Start Factory Reset...
-- Wiping Data...
Formatting /data...
Formatting /cache...
-- Set Factory Reset done...
Data wipe complete.
E: failed to find /misc partition
Click to expand...
Click to collapse
I exit the recovery mode and boot to system. I am asked to connect the device to WiFi. Then, a message appears, stating that "an unauthorized attempt to do a factory reset has been detected. Please log in to a Google Account that has been used with this phone before."
How can I get rid of this message? Is there a way to enable USB-Debugging from command line when the phone is connected to a PC? I just cannot find a guide in which the rooting and installing of a ROM on a locked Galaxy A5 is explained.
I am thankful for every help. If you have any idea, please post below!

Hello, I need to root a Note 3, SM-N9005 ATL Android 5.0 N9005XXUGBOL3. It is encrypted and would like to be able to recover the data that I have. Using the Smart Manager app was restarted and has not returned to start, when it start asking for the decryption key, restarts, lock screen appears and restarts again, staying at the Samsung logo, varying the tone of blue LED and vibrating as if it were to start and again restart.
When I start it in recovery mode I get the error "e:failed to mount /data (Invalid argument)".
I tried to root to see if I can make a backup of the partition /data but it is not possible, I tried flashing by Odin CF-Auto - Root, CWM Recovery, Philz_Touch and TWRP, but I always get error, can only Flash the official recovery and the phone still does not boot.
I have not activated developer mode and I don’t know if I could do it from the recovery or flashing an alternative firmware.
If I couldn’t root it, I have to find a data recovery company, I need to get messages from a Samsung SAT about another terminal that they are repairing, so I would have restored the factory settings to see if it works again.
Can anybody help me?
Thanks.
PD: Sorry for my English.
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.

[HELP] Trying to transfer my rig, now I get a "Verification Failed" message on boot!
This is urgent! Please help1
I tried to transfer my phone's rig to another of the same phone. A guide here said to use TWRP's backup feature. I failed at doing the Odin flash the first couple times and accidentally booted into the system. I got a "Verification Failed" screen, with the only options being factory reset, and power off/restart. I figured this would go away once I flashed TWRP right, so I did, did that backup, but I noticed the backup was only ~4GB. I tried to mount the Data partition, but it reports 0B and won't mount. Every time I boot I get the same screen. I don't know what to do and I have no phone... and I need my data.. Please help!!! EDIT I also can't access TWRP anymore, and the normal recovery says "successfully verify for dmverity hash tree"
SM-G935W8
EDIT EDIT: I managed to boot using the standard recovery's reboot option... But I don't want this to happen again. Is there an easy way?
my Samsung galaxy s7 edge(SM-G935FD) is having this problem . in previous Android versions like Marshmallow it worked very well. But at the end of the Nougat updates, this problem started, suddenly the phone freeze and reboots itself, when it freezes there are multicoloured lines in the display(photo). and heats like hell.
and after the last oreo update killed my phone. its rebooting in a loop, sometimes phone works but for a short time.
I tried to factory data reset. there is this error message E: failed to find /misc partition cant reset or wipe cache.
tried to flash but flashing with ODIN, but it did not fix the issue. cant flash with Re-partition checked
tried TWRP recovery and couldn't wipe files or repair file system, Error message "Unable to Mount /data"
tried to change the file system couldn't do it gives this Error E: recv error on uevent
now after flashing with odin and it stuck on the boot logo
so this is my sad story pls help me guys :crying::crying::crying:
Hey all, First pot here. Hopefully someone can help.
My S8 was stuck at the samsung logo so I restarted it. Tried to do an update and got to about 20% then error. Now when it restarts it says corrupt data and need to wipe. Tried that but fails.
Formatting /data...
E:/sbin/mke2fs_static Failed with status 37
E:format_volume: Failed to make Ext4 on /dev/block/bootdevice/by-name/userdata:
no such file or directory
Data wipe failed
It's not rooted or customized. I cant authorize adb since it wont go past the logo. Also no OEM unlock.
PLEASE help. Thanks!
