Hello,
My friend gave me a Samsung SM-A515F that he bought because he wanted to do a factory reset and could'nt do it because the option was disabled in the settings. The first thing I did is going into recovery mode but there is'nt any option to wipe data. Clicking "reboot to bootloader" option just make a system reboot so I can't go with fastboot. Viewing several howtos I tried to go into Download mode but I did'nt manage to so I assume that it's also broken. And finally, adb show device status as "unauthorized" when using it in recovery so I can't hard reset from there.
Any ideas or suggests would be really helpful,
Thanks a lot
Maybe its a Samsung Knox feature that is activated.

Hie,
I recently purchased a Chinese Tablet (Fondi PAD T708B). I had set a password for it and then forgot it. I read a couple of forums on how to get help, it showed generic password recovery methods for android which seemed not to have been options for this tablet. Then I read another forum which gave me another solution to be to factory reset it. I'm a noob it that sort of thing so i tried to follow the steps correctly. I was able to boot into recovery mode and found the factory reset option which showed it would erase all user data. I had no problem with that considering there wasn't anything I hadn't backed up. However, during the 'wiping data' the tablet went off. And when I tried to boot it again it gets stuck on the screen as shown in the attachment.. And however long I wait it doesn't seem to pass that point. Can any one help me out on this?
May you please help.
Hey guys,
Is data recovery possible after a flash? Also, what is wrong? I have searched but no answer directly hits on this. I am not a tech guy- Biology- sorry for that ahead. To the issue, I dlowded a software update to my Galaxy s3.....and boom froze on Samsung screen. I can turn phone off and on. It would not boot past Samsung. So I went into cache partrition, and tried a system reboot- cannot. So then I seen a program that supposively recovers data after factory reset if you do nothing else to the phone. However, problem I hit te dreaded factory reset- nothing. Over a software update? My computer is not recognizing the device. So I went to Samsung, they tried installing software, however, the computers were recognizing, but not connecting. One tech said they did not have flash- I went back again, the othertech said they did. Anywho, after 4 days, I forked my phone over to a repair guy. He I believe tried Odin- as it currently sits in odin mode. Now it was getting into download mode- but ow I have this message- " Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." A samsung guy mentioned it might be able to be flashed, as my concern data- not backed up. This info is pretty important, as I have several contacts and mssgs. The two modes my phone can go into: Odin and recovery. I could really use the help, on both saving data, and getting the phone to fire- as it might be able to- but data?
Thanks in advance.
Use helium for recovery data

Before or after the a Flash? Thanks for the reply.
[the final word in the title should be the word "removed"].
My phone is a Rook G from EE (UK), which I understand to be just a carrier-branded ZTE Blade 3 A410. I need to wipe the phone and do a Factory Reset . But the phone has Factory Reset Protection, so I must remove this in order to proceed. I do this by removing all google accounts from the device. As a result, I can perform the factory reset from within the "Backup & Reset" section of "Settings".
However, if I boot into recovery (By holding Vol+ and Power simultaneously), then when I choose "Wipe data/Factory reset", the following line appears at the bottom of the screen:
"Frp have not wipe, factory reset failed".
And it doesn't seem that the device is factory reset. So my first question is: WHAT do I do to enable the Wipe data/factory reset feature from recovery?
[If you are wondering why I need to Factory Reset from Recovery, the answer is that I'm trying to unlock the bootloader. Now we know that the last step in unloking the boottloader is that the device is wiped back to Factory Reset state. I presume that this is accomplished by code which runs in the regular recovery partition.
What worries me substantially, therefore, is that if there is some problem which prevents Recovery from wiping the device clean, then it will not be possible to unlock the bootloader. I'm sorry to say that indeed I am not able right now to unlock the bootloader -- at the crucial moment when I would use the Volume key to confirm that I want to unlock, there seems to bea problem with what is happening: the phone screen stops responding, and in the end the procedure for unlocking the bootloader fails.
If anyone can confirm to me that it must be possible to do a factory reset of your device from within Recovery for there to ever be a procdure to unlock the bottloader.
And last but not at all least -- if someone can help me to end the appearance of that crazily ungrammatical error ("Frp not have wipe, factory reset failed"), I'd be very grateful. Because I'm hopeful that this is the key to unlocking my bootloader.

Developer options>Allow OEM unlocking
thanks, but of course I have both Allow OEM unlocking checked and also USB debugging checked. Perhaps it's a clue that the "OM unlocking" toggle seems to be not perfectly sticky. It sometimes/often happens that I check the value and it's gone abck to "off". At this point, i check that value before I do anything that might unlock the bootloader.
But thanks for the suggestion.
BTW -- please note that THIS question here is about how to get Factory Reset to work from Recovery on a phone which has no google account set up. To do THAT surely doesn't require the OEM Unlocking toggle to be set.
I have the blank screen problem, phone works because the notifications are still coming through. Ive seen a few ways to slove this problem, and thought the factory reset was the best option. I attempted to do it but I can't get anything on the screen. Is there another option for me to factory reset the phone? Help is very much appreciated. thanks
Boot the phone onto fastboot, connect to computer, use fastboot commands to erase data and cache.
Hello,
my friends Samsung Galaxy A51 crashed while using it, opening a google docs link she received via WhatsApp.
Restarting the phone will only show Samsung logo, then Samsung Galaxy A51 logo and then dead again. No boot loop.
In the morning the wake up alarm set in the phone plays its chimes but display remains black.
Rebooting phone with holding volume down doesn't work.
The phone is not rooted or flashed.
I can enter Recovery mode. Tried to restart system. Tried to delete cache. Tried to repair apps. None of this changed anything.
I can connect via adb but only in Sideload mode. Hoped to unsintall Samsung Browser as this might be a damaged app. But I don't have permission because USB debugging is not toggled. I tried adb restart and adb restart recovery. Phone will no restart to Android. Restarting to recovery works but doesn't solve the problem.
I can bring the phone to Download mode. Btw. none of the tutorials helped to do this. At some point I double-tapped the power button and was surprised to get into Download mode. I wanted to flash TWRP recovery to the phone to get more options to backup and recovery. Unfortunatley the OEM protection did not allow me to flash TWRP recovery.
My friend is from Ukraine and has her Ukrainian banking app registered with this phone and currently no other possibility to access her bank account. Also she has a lot of data like contacts, messages, photos and videos only on this phone. So we can not do a factory reset.
Do you have any other ideas for troubleshooting?
Do you have any ideas how to remove OEM protection without access to OS so I can at least flash TWRP and do a backup?
Do you have any other idea how I could backup the phone?
Unfortunately I still have not been successful to get the phone working again or to backup or read any data.
Just to add another information: I drained the battery to 0% so the phone was totally dead. I was not optimistic that this full power off might help any more than the restarts I did so far. But running out of ideas. It didn't help or change anything.
I'm afraid only a factory reset could at least repair the phone :-(

Without OEM-Unlocking and USB-Debugging you will not be able to install TWRP and if so then all data would be gone automatically anyway, as this is equivalent to a factory reset.
The only way would be to download the STOCK-ROM with "Frija" (quick and free) and flash it with "Odin". Of course, the mobile phone is then virgin and has to be set up again from the beginning. A Google login restores a lot of data. Setting up the banking app again (username & password, etc.) shouldn't be a problem either.
Of course you can also try a factory reset first, but setting up a completely new one is not avoided here either.
Much luck!
