[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] Encryption Failure

Hello. So after spending a couple of hours searching for an answer, I couldn't seem to find one that could actually help me. I have a GT-N8013 Samsung Galaxy Note 10.1. I have CWM installed, and a 64GB microSD card mounted using the app2SDscript. I did not make a recovery image.
My problem right now happened all of a sudden. My tablet was low and I had forgotten to charge it, so it turned off, but for some reason it just froze at the logo. So, I plugged it into the charger and restarted the tablet. When loading everything was going well, but before I got to my home screen, my tablet just gets stuck after loading. Then an error appears and says that "Encryption failed. Unable to complete encryption due to interruption. Perform factory data reset." The funny thing is that I haven't even attempted to encrypt my tablet at all. So now I'm completely stuck and really just don't know what to do anymore. I can still get into CWM and download mode. Help please.
What I've attempted:
Wipe date/factory reset through CWM - failed
(while attempting to use CWM, I noticed that CWM couldn't load/open/mount anything)
Wipe cache - failed
Tried flashing stock ROM through odin - failed
6 month old tablet. Help please :crying:

i have the same problem, any ideas?

[Q] Mount Problems

Hey, I need some help.
CyanogenMod doesn't mount my sdcard anymore. I mean its mounted but cannot be used (sdcard is in /data/media/0 are the files but there's no /storage/emulated/0). My Recovery is also showing after every operation that its unable to mount 'persistent'. And then my sim is not working and the camera force-closes.
That all started by me dropping my phone - Crack in the glass. So I saw some tutorials on how to switch the screen. Shouldnt be really difficult and just to try I opened the back of the n5 and closed it with not even really touching any of the hardware I closed it. Then I tried to boot from my CyanogenMod so I got my bootanimation and then a **** ton of pop ups telling that probably everything is crashing. Pressed ok, ok, ok and it showed the boot animation again. Same again and again. It didn't even asked to decrypt the phone >.<
So I turned it off and started the recovery (TWRP), which was showing E: Unable to mount 'persistent'. Had no idea what to do and why soooo
- Factory Reset - flashed another version of cm back on
Same ****
- Complete wipe (Backuped my files) - flashed
I got to the GUI but no sdcard mounted
- Tried to flash Stock ROM from Google - Bootloop and of course no recovery
- Another Factory Reset plus cm flash
Same as after the wipe
- Tried another version of TWRP
Same
So what should I do? Did I broke my phone by opening the back?
I hope not so it would be awesome if you could help a kinda noob like me

[Q] Decryption Unsuccessful Error - Cannot boot

I have a Samsung Galaxy tab 2 GT-P5110 which I had successfully installed CM12 onto. I decided to set up work email which insisted that I encrypt the device. I believe that the process completed successfully.
At that point I decided that I would like to flash the device with CM12.1. Restarted the process (Factory reset, Wipe Cache, Wipe dalvik cache) and flash the new CM12.1 zip file from external SD card.
I cannot now get to the recovery mode and the device doesn't always boot into anything recogniseable. The screen goes black and blacker! I have manaed to get to the CM logo and then a screen asking me for the PIN for the encryption. The next screen tells me that the PIN is right but the data is corrupt. It gives me the option to "RESET TABLET" but that really doesn't do anything and won't let me in to the recovery menu.
I can get into the Download mode and connect Heimdall up to it.
Is there anything that anyone can point me at that will help me to unbrick it?
I hope I've passed on enough information to help. It seems to me I need to somehow re-format the internal SD but I can't get to any menu that will allow me to do that.
Any thoughts anyone?

Fixed It
I seem to have fixed it. I flashed the CWM Recovery rather than the recovery that I had been trying to use and I got control of the device back. Not sure why that made a difference but this time the Android Robot came on screen with the 3D polygon rotating inside it and it seems to be running correctly now and updated to Android 5.1 ... Magic!

Huawei Ascend 540-U01 must reinstall from scratch

Hi there!
I have this Huawei Ascend 540-U01, from Portugal, running (or not running) its original rom. It was working find until it start to run slow. At boot it was blinking a half screen wite square, from time to time it shows "process com.android.play stoped" and some other times "com.android.google stoped". At this point I decided to enter in recovery mode and wipe cache and reset to factory defaults. The problem ware not fixed with this action and I decided to "scan system" from the recovery mode too. It showed lots of files corrupted. Knowing it woldn't solve nothing I tryed again for a reset. Now, the system simply don't boot, but I'm able to reach the recovery mode.
May anyone guide me (or point me) to re-install the stock rom for this device? It was not rooted and I can't boot on normal mode.
Thanks
