Hey everyone,
I'm managing some Android phones in company using VMWare Workspace One and today, when I unenrolled phone using console of MDM, it says unenrolled but nothing happened with the phone. Thanks to that I got now device, which seems like unenrolled from MDM side, but device thinks that it's enrolled and still got installed our policies.
In our policies we have restricted to do factory reset on the phone and also developers settings, so I'm actually unable to flash new firmware over ADB. Factory reset over recovery also doesn't work, I'm missing "wipe data/factory reset" section in the recovery on the phone. Devices are not rooted and with OEM system.
Is there any way, how to rescue that device? I just need to wipe it into factory reset and reenroll that device using KNOX Enrollment again.
Thanks.

I am on A9192: HTC Inspire 4G.
My mobile got locked by too many patterns attempted. It asked for email and password, though I provided right information, it didn't let me go through.
I tried few options from Cannot unlock tablet as have no internet connection? but none of the option worked for me.
Anyway, I tried to factory reset through its stock recovery which is in chinese and labelled as `HTC ACE v4.0.0.2`.
I selected `wipe data/factory reset` which could have uninstalled the ROM on it. So, now my mobile is showing company logo only.
Every time I go to mount and storage menu, I find system, cache and data are unmounted. Though I mount and reboot the boot, it again gets unmounted.
What to do now ? I know this phone is rooted but I don't know if its bootloader is unlocked or not. It shows S-OFF on bootloader menu. Is it possible to install the system again ?
It's my goal to wipe a second hand android device I received.
You used to be able to do this via the encryption option.
Though now that I am on Lollipop when I enable encryption the phone (2014 Moto x) restarts and doesn't do the full wipe like android used to. Though does come up with encryption enabled.
I assume this has to do with Lolipop having encryption enabled by default.
Before I get all answers telling me to do a factory reset. No a factory reset doesn't wipe a system it just repartitions it and gives new encryption keys.
Tried in safemode too. Nothing
Just getting a new encreyption key via a factory reset doesn't do what I want. That key could be recovered and the data still exists. That's why tools like truecrypt ot luks if you have experience take so long to encrypt.
[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.
Device is running all stock HTC and Verizon software. Never rooted, never encrypted phone.
Phone now boots to a screen that says:
'Decrypt storage'
No matter what I enter for a password, it states:
"The password you entered is correct, but unfortunately your data is corrupt."
The only option provided is to 'Reset phone'.
Before I wipe all data with a factory reset, is there any chance of trying to recover data from the phone? Phone is not in USB mode so ADB doesn't recognize the device. Various hard resets don't do anything. Are there any tools that can allow me to look at the device memory before simply wiping everything and starting over?
me too
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.
