Can't factory reset

My GPS has been crapping out so I'm trying to do a factory reset. Go through the steps and it just hangs on the little green android dude after I initiate the factory reset. Finally got the nerve to just power it down and restart and it boots to the home screen as though nothing happened . . .

Would you mind detailing what steps you went through?
I'm curious because it sounds like you did a factory reset through the rom you're running.
Ever attempt a factory reset and cache clear via CWM or TWRP (not sure of its proper acronym excuse the error)

[Q] Stuck at encryption unsuccessful - Impossible to factory reset

Hello,
This morning, I was reading comics on my tablet, an it froze completely. The touchscreen and buttons were not responding so I held the power button to turn it off. I turned it on again, and I had an "Encryption unsuccessful" message, saying that I needed to perform a factory reset. The problem is that I never set up my tablet with encryption...
That being said, this screen pops in when my tablet starts, and there is nothing else I can do but to turn it off. I tried the following :
Reboot
Reboot to safe mode
Launch the recovery mode and launch the Android icon (I don't know what it's here for)
Launch the recovery mode and launch a factory reset
The factory reset starts for less than one second before showing the Android sign with a red alert triangle, and resets the tablet. At this point, nothing worked, I am still stuck with this screen, I don't really see what I can do.
I bought my tablet in the US in 2012, it runs Jelly Beans if I recall correctly (the ASUS version, I never rooted it). I have a Mac running Mountain Lion if it can help. Does anyone know what I can try now ?
Thank you in advance for your help

Is the bootloader unlocked ?

No, it is the default bootloader. Everything is standard, I never felt the need to modify the OS of my tablet. Do you have a theory?

[Q] went to unlock/root and stuck on boot image.

First off, MODS please let me know if this is the wrong section but as it was about rooting/unlocking the nexus 9 I figured this was the correct forum.
I went with chain fires unlocking method, after unlocking and rebooting i forgot to go back and set the device up and enable USB debugging priot to rooting. Now where my problem lies is since that mistake my device attempts to reboot but sticks at rebooting with the spinning red, green, blue, and yellow dot spinning in somewhat of a circle like its attempting to boot but it never goes anywhere. This appears to be a boot loop minus a restart in between time. anyone have an idea of how to start this and start from scratch? Any help will be much appreciated.
Did you try to factory reset? Boot into boot loader and factory reset

Yes, i was able to resolve it. I downloaded the nexus tool kit, relocked and loaded stock firmware back on it, this fixed the issue, then using the nexus tool kit reunlocked and rooted with no problem. unsure why it got stuck on the boot image but all is resolved now running fire and ice kernal with dirty unicorns ROM.
thanks for the suggestion though.

Samsun galaxy alpha become sluggish, and freezes on at&t logo

A better solution is to flash official firmware using odin instead of factory reset.
Thanks. I did that and got my device back to life.

Stuck in bootloop, potential soft/hard brick

Hello XDA.
After whipping my Moto E out the other day, I noticed that turning it on results in it just... laying there and showing me the "WARNING - BOOTLOADER UNLOCKED" message.
Around 1 1/2 years ago, it just turned itself on after clicking the power button once. Now, not even Fastboot mode helps, as choosing any of the options listed there results in the warning mentioned above. For clarification, here is everything in short:
The phone does NOT turn on normally
Using any option in the Fastboot boot menu restarts the loop (i. e. instantly goes back to warning message)
NEITHER does Minimal ADB and Fastboot recognize the device, NOR does the phone recognize the connection to any PC (I've tried 4 different PCs)
Since Fastboot is unresponsive, suggestions to restore stock recovery are useless to me
Suggestions to perform a factory reset are also useless, since Fastboot is unresponsive.
So, am I right if I suppose that this is a hard brick? Or is this somehow salvageable? If so, please help me...
Thanks in advance!

If its stuck on boot, its definitely not hard brick.
What was the android version when you wiped data?
Was there any custom recovery you used to wipe data?
You possibly wiped /system too, wiping system can result in bootloop.

I'm not sure about it, but I think it was 4.x.

Sorry, but that doesn't make sense. The phone's been rooted for almost 2 years now, and 1 year ago, it turned on perfectly fine.
But let's assume that actually happened somehow, how do I recover from this?
