Figured I'd post this here since I didn't get any other replies in the Nexus forum.
I have been trying to wipe my Nexus 7 (2012) clear but the wipe functionality doesn't appear to work.
I've been rooted on stock (using TWRP) but recently sideload 4.4.2 and removed root in the process.
OTA installed and I root was removed but recovery is now showing "no commands".
I have been able to get past that sometimes but not consistently and using the recovery wipe/factory reset doesn't do anything.
I tried to fastboot and do a wipe from the command line but that doesn't seem to be working either.
The device won't boot properly, it crashes after a few seconds once loaded and automatically restarts so I wanted to clean everything up and start fresh.
I tried custom temp recovery (since it's the only option available to boot from fastload) and while I can get into temp TWRP the wipe option doesn't do anything.
I also tried to reinstall the bootloading from the 4.4.2 image but that didn't help.
Any ideas what else I may be able to try?

Been getting frustrated over the past day.
Currently am up and running on a backup of Hyperdrive RLS 8.1, but I am afraid to reboot because for all of last night, any backup or clean install of any ROM I flashed would either
1) boot up the first time, but any subsequent reboots would result in stuck at the Samsung Custom Lock screen
2) not boot up at all, stuck at the Samsung Custom Lock screen
When I get stuck at the Custom Lock screen, I do a battery pull and then attempt to reboot into recovery. However, trying to boot recovery would not work (phone reboots itself after briefly showing "booting recovery" every time) until I plugged in the charger and tried to boot recovery (not sure if just coincidence?). Currently running TWRP 2.5.0.2
At this point, the recovery asks for a password (I have never set a password, don't know why this happens?). This prevents me from factory resetting (gives me an operation failed) because I need to "decrypt data" or something along those lines, using a password which I am sure I have never set. The internal storage is apparently unable to mount without decrypting data using a password..?
I found that in the WIPE menu I can perform the FORMAT DATA action which is successful and fixes the decrypt data problem, and I am able to factory reset and then restore a working ROM or install a new one (I tried CleanROM 1.6 with patch to 1.6.5 since it was on my sdcard).
This brings me to this position at the current moment. After formatting and factory resetting, I have done the following with such results:
1) Restoring my STOCK, ROOTED TWRP backup from before my install of Hyperdrive 8.1. Booted up fine, but a reboot gave the same results of stuck at the custom lock screen
2) Installing CleanROM, booted up fine the first time, but got stuck on the first reboot at the first bootup screen (it changed it to the original
Samsung Galaxy S4" instead of the custom lock?). I went back to recovery and went through the same process (decrypt by formatting data, factory reset, restore/install new rom)
3) Restoring my Hyperdrive 8.1 TWRP backup (first backup of the ROM while it was apparently running fine, reboots were normal and no problems yet). I am currently running this right now but have not attempted a reboot because I do not have the time for the next few days to mess around with my phone.
Summary: Stuck at initial boot screen (Custom Lock or Samsung Galaxy S4), TWRP 2.5.0.2 asks for password for decrypt?? & cannot factory reset, able to format data which allows factory reset after, restored Hyperdrive 8.1 backup, currently afraid to reboot in fear of getting stuck again.
Any help or suggestions would be appreciated. I am considering ODIN a stock image and completely starting over, but that will have to wait until the weekend.
So, I was able to successfully unlock my bootloader, got TWRP 2.6 on it, and put a few different ROMs on my machine; however, I have yet been able to install a ROM and get it to move past the boot animation.
I have tried the latest nightly ROMs for CyanogenMod 10.1 and 10.2 for my TF201, both of which get stuck in CM's boot animation. I just tried the same with the newest Baked ROM, only to be stuck in its boot animation as well.
I'm trying to figure out if there was something I forgot to do. I have been able to revert to a backup of my stock Jellybean 4.1.1 that I stored using TWRP, but haven't been able to use anything else.
Are there any thoughts on this? Have I missed something? I was able to use the unlocker utility and each boot offers the confirmation in the top-left that my bootloader is unlocked. I am able to enter TWRP from the recovery mode. Shouldn't it be as simple as selecting a ROM's zip archive and installing it from TWRP?
Have you done a full wipe before installing, including cache and dalvik cache partitions?

Try installing twrp 2.5. AS I just read in another thread there are problems with 2.6..

Factory reset
After flashing CM 10.1 nightly last night i had the same issue. I booted into my recovery console (flatline cwm) and performed a factory reset. This seemed to clear whatever issue was bothering the tablet. Still sat there for about five minutes on the animation after the reset but then progressed into setup.
Doubt if it makes a difference but mine was connected to the dock too.
If you're still stuck the method that worked for me yesterday was:
Used Flatline CWM as the recovery, installed using fastboot
Used an external memory card to copy the relevant zip files to my sdcard, recovery couldnt find them otherwise using adb push
Installed from zip using Flatline CWM
Installed gapps using Flatline CWM
Booted, got the issue you had
Booted into recovery, performed a factory reset
Told recovery to restart the machine
Booted into setup screen after loading for a few minutes
I was using CWM 6.0.4.3 to flash Android Revolution 52.0. When I rebooted the device after the install, the CWM would not load and it just bootlooped with the HTC dev screen.
I tried to load TWRP, bootloop.
I tried Philz, bootloop.
I cannot access and recovery to completely wipe the phone and start over. I tried using fastboot command to erase the phone and am getting a remote not allowed. Am I screwed?
Any help is totally welcome.
Solution
I was able to fix the issue.
In CWM, I was able to use the command
fastboot erase cache
When I restarted the recovery, I was able to restore a backup I made just before trying to install AR 52.0.
Also interesting note, I seem to be having an issue with Sense-based ROM's now. AR used to run solid on my device, I had issues with 51.0 having Sense crash and even Viper 5.5 was having problems with the Hub crashing and not responding.
Not sure why but just saying.
I was using the Nightly ROM and when i tried to flash an update, my NEXUS 9 went into a boot loop(I had lost root earlier). I was able to go into recovery but even after flashing the lastest zip, had the same bootloop problem. SO i decided to flash an updated SU hoping to get back root privelages. and reflash Nightly, G apps and SU. Still bootloop (Overnight)
After all this i did the mistake of doing an Advanced Wipe which wiped all the data on the device. When I go into recovery i get the "Keep system read only message"
Unable to load any ROM or Flash it. Please help.
Trying to use fastboot to load the factory image
At the moment , trying to flash in the factory image for the NEXUS 9 to restore the system , boot.
https://forum.xda-developers.com/nexus-9/general/guide-how-to-unlock-bootloader-flash-t3035153
is very useful.
But i am wondering is there another way around this mistake.

You have to select not to keep system read only. If you're having trouble flashing the factory image, try using wugfresh nexus root toolkit. It's here in the forum. It installs on PC and it downloads and flashes everything for you. It has some great features.

I am currently having the same issue. I am using wugfresh toolkit. to get it back to stock and start over. Don't know why it is not wanting to read data. Never had this issue until today. It looks like wugfresh saved the day.
I did something stupid when trying to root a SM-T380 that I just got as a backup tablet. I am new to the samsung world and ODIN.
I got as far as flashing TWRP and booting into TWRP using the instructions from androidinfotech and I actually had to do this multiple times as the system kept rebooting (I did not uncheck the auto reboot at first) and resetting the boot loader.
So I got TWRP installed, but...
I was trying to clear the cache as the instructions were saying, but I could not get anything mounted and cleared. So I followed some stupid video that had me go into the advanced and change the file system to F2FS, wipe and then go back to I guess EXT4. Well, Now I am in a boot loop. I still can get into twrp and at this point would love to go back to stock and call it a day. I am "Slow" downloading a stock image for the device, but that is still hours from completion.
Is there anything I can try in twrp while i'm waiting?
