[Q] Nexus S (wind mobile) can't factory reset! (jellybean)

Hi, first post here.
So I bought a Nexus S that was rooted and updated to Jellybean. It's an unlocked phone originally locked to Wind Mobile.
So it's been having issues with getting stuck on the google logo after reboot, so I decided to sell it. Problem is when I go to factory reset the phone it shows the reset bar but then that turns into a big triangle with an exclamation mark on it with a little android guy next to it. The phone gets stuck there. All I can do from there is remove the battery.
From there I tried going on bootloader using power and volume up (says unlocked btw), and from there I load recovery. On recovery there is an option to factory reset and I click on there, however it doesn't do it. This is what I says:
"--wiping data...
formatting /data...
E:format_volume: make_extf4fs failed on /dev/blo/ck/platform/s3c-sdhci.0/by-name/userdata
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure...
Error mounting /sdcard/ .android_secure!
Skipping format...
Data wipe complete."
So I think the error might be accociated to the sd card because the Nexus S doesn't come with an sd card, it has built in memory? Also on recory when choose "mount sd card" it says"Error mounting /sdcard!".
So how do I go about fixing my problematic phone? I have a dude that wants to buy it but I can't even reset the damn thing, let alone fix the freezing at start up issue. I am also totally new to this.
Extra info: When the phone freezes at the google logo at start up I get passed that by using a blow dryer on the phone. That's the only way I start up the phone after the battery comes out. This is the gt-i9020t model.

Are you using a custom recovery? If not, that might be the reason your phone is behaving like that as I had the same issue like yours when I first started flashing things!

I don't know if it's a custom recovery because the previous owner installed everything/rooted.
When I press power and vol. up, It looks identical to the uploaded picture's bootloader/recovery.

Its a custom recovery (Clockworkmod) ok. I'm not familiar with it but there should be a setting somewhere - maybe in "advanced" - where you have the option of restoring default settings for the recovery. Do that and then try doing factory reset again.

In advanced there is no option that worked.

*Solution*
Ok so for those having this problem this is what I dug up:
Internal SD card error causes the boot freeze/factory reset error. When you try mounting SD card it fails, this is also what makes me think it's a fault with the phone's internal SD card.
I do not know how to "fix" this fault, however I'll tell you what I did to get passed this issue.
1) Heating up the phone helps bypass the frozen screen. On Boot it goes to the google logo and freezes, but you can get passed this by heating up the phone (using a blow dryer) before hand and it's relatively successful.
2) I believe that before factory resetting the phone (whether using recovery or the actual reset option on settings), if you heat up the phone, it might work the same way it works when booting up.
I did not try 2) because I managed to "reset" my phone manually by uninstalling all apps, deleting all files/cache/photo's/accounts, and by clearing all app data. This works just as fine if you ask me.
Overall this solution has not been "fixed", I encourage people to find a real fix, but for now using the blow dryer and manually resetting is one way around the problem.

[Q] Factory Reset Did Not Wipe Anyhing

I'm trying to remove apps that's on this phone (GT-S7500) because some of the apps always force close and not working. Firstly, I tried uninstall the apps one by one, all went good until I rebooted the device, all of the apps are back again. Second, went to privacy>erase everything including SD card content, device rebooted and went straight to recovery. It was weird because normally it will reboot itself straight to home screen. So I select the option factory reset/wipe data, after that wipe cache partition and reboot. Device does not reboot but turned off completely (weird again) Turned it back on, and only saw that none of the apps were removed. Even the wallpaper are still the same. Next thing I do is manually boot into recovery menu and factory reset again, still the same thing, (device turned off without rebooting itself, turned it back on and everything was still the same) after few tries again, I finally decided to flash a stock rom with ODIN. Flashing was successful ODIN shows PASS, waiting device reboot but it shut off completely again. turned it back on, but nothing changes. wallpaper are still the same and every single downloaded apps were still there. Went to settings> about device only to found that it wasn't the same rom that I've flashed earlier using ODIN.(flashed 2-3 times again, results still the same) Very confused right now, suspected that the internal SD card was corrupted/damaged. Does anyone experiencing such thing on your galaxy ace plus? searched on xda forums and found that this issue was also happening on few other devices. This is not my phone, just helping a customer. Thank You.

[q] motorola xoom 4g lte verizon model mz602 wont reset at all. It says bp failed

HELLO EVERYONE,
this is my first time ever posting, I have a very weird issue with my Motorola xoom tablet, this is a Verizon Motorola xoom 4g model mz602.
the issue I am having is that every time I try to factory reset my tablet it goes back to the WAY it was left, what I mean is that it wont reset at all,
I tried everything from factory reset on RECOVERY mode to RSD lite program using factory SFB file and FAST BOOT COMMANDS, and nothing is working,
the weird thing is that THEY all say that they were SUCCESSFUL to reset and stuff, but when tablet reboots its back at the exact same way it was, same apps, say google account, same wifi network , everything is the same as if it was not resetted at all, when I tried the FACTORY RESET from recovery it says this
wiping data
performing BP clear
BP CLEAR FAILED.
formatting data
formatting cache
data wipe complete
but then when the tablet reboots same thing, tablet is back to the way it is with all the user data and all the information there,
when I say I tried everything I mean everything, I unlocked the OEM to to try to install a custom rom but when I try to install the custom recovery the tablet will reset back to its original RECOVERY. I even followed the GUIDE to make sure to go STRAIGHT into recovery to avoid the INITIAL boot to restore the original recovery, but it will not work, so like I said, when I try to restore the image using RSD lite, computer shows as if everything succeeded on RSD lite, but it doest work, FAST BOOT commands from ADB show successful or completed, but same thing, please some body help .
thank you in advance

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

[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.

Phone thinks it is encrypted

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?
