Frp bug(?) --Cannot Wipe the device from Recovery, even with all Google accounts remo - General Questions and Answers

[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.

[Q] Wipe data/ factory reset soft bricked my phone

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 ?

Will I lose software update after a hard reset?

I am 100% certain that this question has been asked already, but a search mostly shows people asking about what happens when they do a factory reset, or even when they say "hard reset", they appear to have in mind the "soft" factory reset instead.
My question is as the subject says. If I do a hard reset, the one performed from the android boot menu or whatever you call it, will I lose my software update? I am NOT talking about the factory reset that is performed from within the settings menu of the device.
Just as a background, I have a Nexus 7 (2012, first generation) that simply does not recognize usb cable while it's turned on. While the tablet is turned on, it does not charge and it won't be recognized when plugged into the computer. It charges only if it's turned off. I searched and did everything suggested, using the original cable, original charger, different cable, different charger, cleaning the usb connector with 99% isopropyl alcohol, try bending the connector slightly, software update, factory reset, installing some apps suggested from google play store and running diagnostics, everything. I have to think that this is probably a software issue, not a hardware issue. I mean, obviously it does charge when it's off, so I just can't think something is catastrophically wrong with the hardware (and I have experience fixing wonky touchscreen on this device by updating software). Unfortunately, rooting the device and installing custom rom is not an option until the usb works, which is the whole issue that I am trying to solve (I saw some discussions on the web about rooting without usb, but I think that's beyond my ability).
Anyway, back to the point, as one of the last resorts, I am wondering if a hard reset might give me some light, but before I attempt that, would like to know if that means I need to update software again. Yes, I already know I will lose all my files, data, apps, contacts, app save files or progress, account info, everything.
Thank you for your help.
There is no difference between hard reset and factory reset. Factory reset or hard reset just removes your all system apps data, user apps and data. It only reset settings to default as a fresh os.
By factory resetting it not change your updated os to older one. It just reset your android update to factory settings.
If it helped . Please thank me.

So are the discussions at the following link incorrect? Please Google "how to hard reset nexus 7 2012" and click the top hit that shows, by the title "Hard Reset your Google Nexus 7 (2012) – Android Forum - AndroidPIT" (I am a new user to these forums and am prevented from posting an external link).
I was thinking of trying the second method explained in that article,
- Turn your tablet off.
- With the tablet off, press and hold the Power key, then press and hold the Volume Down key. Scroll down twice to select Recovery.
- Select with the power key.
- You'll see the Android pop up, then while holding down Power, press Volume Up.
- Use the volume keys to scroll to "Wipe Data/Factory Reset" and press Power to select it.
- Scroll down to "Yes - Erase All User Data" and press Power to select it.
- Your Hard Reset is now complete.

Ashwinrg, could you please reconcile your post with the above article that I am referencing, which suggests that a "factory reset" is different from a "hard reset"? Am I reading something wrong, or is that article plain wrong? (And yes, even the steps for a "hard reset" references "Wipe Data/Factory Reset", so there is definitely some confusing terminology, even at the manufacturer level, going on here, but my point is, is there just one kind of "reset" for Android, or are there more than one kind of "resets" out there for Androids?)
You can see the steps given on the site is saying that go to recovery mode and select wipe data/factory reset.
Factory reset and hard reset is same. It just reset os to factory settings.

Thanks. So to see if I understand it right, if I've already tried factory reset from android settings menu, trying the method with power button and volume button and recovery mode and so on is going to be redundant, and in any case definitely won't have any impact on my usb/battery issue, if the factory reset didn't help?
Yes there might be the case you can loose your data or some software if you will hard reset.
You can factory reset your android in android settings menu or from recovery mode.

Cant seem to factory reset my e6653 nougat

Hello everyone,im having a huge issue with my device of late. It randomly just freezes up now and then and i have to do a hard reset to switch it off then. Since this has been happening i decided to do a factory reset on my device and start fresh.
Problem with that is that my phone wont let me do a factory reset by going into the settings menu and then selecting backup & reset and then going into the factory reset menu. Once there and i try to tap the reset tab, it does nothing at all. Is there another way that i can reset my device?
If anyone has any suggestions for me,id really appreciate hearing from you. My device is the E6653 and it is not rooted or bootloader unlocked if thats essential.
since factory reset is next to re flashing your device
consider reflashing using FLASHTOOL. ( even when you device has locked bootloader you can still flash untouched rom)
some time back a user having z5p ( device name Satsuki) was asking how to flash so i gave him good short tutorial at
https://forum.xda-developers.com/showpost.php?p=71394777&postcount=3
the same applies for you too! but select SUMIRE in the list and see your country , select correct build version / download and flash

Nokia 3.4 unable to wipe data.

Hi all,
I'm having issues wiping the data via recovery mode. I don't have the option to do it. The only options I have is the boot to bootloader, or exit.
The phone is fully charged. The only reason why I need to wipe the data is because my daughter changed her password but can't remember what it is fully. I.e. where she may of put spaces or capital letters.
Any ideas what I can try? The bootloader is showing as locked and I can't seem to find a way to unlock it without turning on developers options.

Unable to factory reset

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.
