Use nexus root toolkit to temporarily boot into recovery and wipe everything, then flash a ROM, or download a factory image from Google and run the flash-all.bat

Can you get to the bootloader? If so, fastboot flash the factory image.

If you need help we need more than "doesn't work".
What exactly happens? Error message? Does it flash normally but once you reboot goes into bootloop again? Be precise, I know english doesn't seem to be your first language but we need to know more

After flashing it, did you go into the stock recovery to factory wipe data before booting it up? You have to do this or else you will get stuck at the Nexus bootup screen. Happened to me once. Apparently you have to do this on the Nexus 5 and Nexus 7 because flashing it doesn't properly wipe the partition.

Hloo m.charesa,of course I wipe data,partition after flashing many times(I watched the clip in youtube does that),But unfortunately due to the nexus logo.

It seems that the problem is not to activate the USB debugging , because after opening bootloader or installing stock rom returns the device to its origin and must be activate (usb debugging) again .. Question: Is there a way to activate it without the operation the system (because its not operation originally)??​

USB Debugging is only necessary if you are trying to use ADB when the phone is on and booted into the OS already. It's not necessary when you are in Fastboot mode (at the bootloader). Not sure why it's not working flashing the factory image. This is why I prefer not to use toolkits and do everything manually. That way, you know where things went wrong.

TWRP Password

I just unlocked my Nexus 10 on 4.2.2 and when I boot into twrp it asks for a password. The problem is I never set a password for twrp so I have no idea what it could be.
Any thoughts?
Thanks!!
I just hit cancel and it seemed to work.
You using the toolkit?
It asked for the password for me,but when i backed out of it (not entering password) trying to factory reset failed on me
When you unlock the device you need to do a factory reset, let it boot and then enter the recovery. Otherwise it may have issues mounting the cache partition as well as the password issue.

You have to manually go into recovery and hit factory reset
Turn off phone
Go into bootloader,from there select recovery
Then choose factory reset you good
Fixed for me.

I was switching TWRP versions and got this problem. So all I did was reboot my tablet even though the prompt said I had no OS installed, I rebooted but did so straight back into twrp. and thats on my Asus Tf700. If you didnt originally use fastboot to get it on there, try it. If so, try downloading and using a different fastboot.exe cause one that I had tried once was broken. Hope this helps.

It didn't help me on my Nexus 5. TWRP asking me about a password and I can't remove it, or flash another recovery or do the factory recet.
I can only boot another recovery like cwm or stok, but I can't mount boot, cace, firmware or USB. Olly system.
It seems there are some problems with bootloader or flash-memory
If
fastboot erase recovery
fastboot flash recovery nameofrecovery.img
Does not work than its possible that its hardware but I would do a full format of device first

[Q] Need some help please

I have a Nexus 7 wifi, It is stuck at the Google screen boot looping. It is unlocked and has TWRP 2.5 which I can access. I have tried every tool kit to no avail. Need some help please!
dont use a toolkit
get to a command line and figure out whats wrong by trying to flash a factory image, or run factory reset in recovery and see if it fixes it.

I tried factory reset but it fails. I tried to flash a factory image through side load but it fails.
If I go to advanced wipe and do them one at a time they all work except data.
It appears to have nothing on intrenal or external storage.
One other thing is when I try to mount the system in twrp it asks for a password?
I have never setup a password so I don't understand this.
Thanks
Did you encrypt your device?

No, not at all that's what's so strange.
I purchased it new and it started locking up and after an attempted factory reset here we are.

Factory reset would wipe data partition leaving nothing in data. Makes sense that it wouldnt let you wipe that when there is nothing there.
Try flashing a factory image from fast boot. Not from recovery.
Sent from my Galaxy Nexus
Would it not have to be loaded on the device? I tried it with a tool kit and it gets to the end and fails on verification.
I don't remember what version it was so that doesn't help. I think it was 4.1.2
But not positive.

Okay seems to be a problem with twrp 2.5 as far as the password I'm downloading 2.6 now.
Use fastboot to flash new recovery and system partition. You run fastboot commands from your computer not from recovery and your device needs to be in bootloader not recovery. It does not require you to load it onto the device prior

[Q] Nexus 4: Can't wipe/Flash factory image. Semi-bricked phone.

Earlier today my phone was working fine running Stock 4.4.1/Kernel. I decided I wanted to get the franco kernel so I got the .img file from the xda thread. I flashed the .img file onto the boot partition using fastboot, and restarted my phone. After a few minutes of sitting at the "Google" screen I rebooted into the bootloader. I tried flashing the 4.4 factory image using the "flash-all.bat" without wiping anything. My phone continued to get stuck at the "Google" screen after multiple reboots. I then tried to wipe my device using fastboot. However, when using the command "fastboot erase system" I got an error that said "Failed: unknown chunk type." I kept on retrying the wipe to no avail. I found this thread: http://forum.xda-developers.com/showthread.php?t=2347060 and followed the steps. All the steps seemed to work up until I had to flash the given factory image using fastboot. I got the same "Unknown chunk type" when the cmd was trying to write files to the "system partition." Before you ask, yes my fastboot/adb is updated to the newest version. (I triple checked) And all my drivers work properly. I just flashed the 4.4.1 firmware 3 days ago using fastboot and everything went perfectly, including the wipe. Please offer any solutions you think could get me out of this situation. Thank you.

Never encountered something like this, but maybe from bootloader u can get into ur stock recovery & wipe cahce & wipe data.
once again I never had that issue...so its upto u...but might be worth a try...if u had made a backup or dont care about the data in ur phone then it did be easier for u u to try
Flash the factory images and erase all partitions on the device. If you want to get some data from the internal memory you could pull it through recovery. Next time read more do less. Franko's kernel uses different ram disk than the stock one. You could also try to flash a full stock kernel for your build first. Get it from the factory images and flash it through fastboot.

Can you get into bootloader mode. It's worth a try. Your not bricked if it can turn on. Your emmc may be bad and flashing the factory image won't work. But if that's the case then warranty or replacement are your only options.

I am also having this problem accept for i am running CWM Recovery instead of stock... First started for me when I went from stock to flashing CyanogenMod 11 from ROM Toolbox Pro (I would not recommend, I didn't do it on purpose) it flashed dirty CM over stock and now will not do anything even when restoring a stock backup. I am going to attempt to run the stock fastboot .tgz.

Normally it could happen when flashing...
For me it was a month after flashing
I had no signal, then rebooted the phone and ... did not boot up
After installing stock 4.2.1 it booted. But phone functions are dead now.
What a pity that we didn't do a EFS backup...

Can't flash ANY ROM on nexus 7 2012 wifi

Everytime no matter what ROM I flash on this tablet I just get a bootloop and then I can't do anything in recovery like mounting SD card for instance.
I'm not completely new to this game, I have a nexus 5 that I'm always playing with and never had problems like this with the s3 or HTC one x. Could I be over looking something? Any help or guidance is much appreciated.
Cheers
Anyone?
I have a similar problem. I flashed ParanoidAndroid yesterday and everything seemed okay but now everything I try to launch or install an app the tablet reboots, and I tried to flash cyanogen, flash stock, do all the wipes and factory resets but always reboots to the damaged Paranoid Android ROM.
Reformat /system /cache /data
Then use a otg cable with a USB drive with the ROM you want

Hey, I'm having the exact (more or less) same issue: http://forum.xda-developers.com/showthread.php?t=2783720
I've been using Cyanogenmod, but other than that, I have the same thing going on.
I was actually glad to see this, as it means I'm not alone in this issue!
But still rather strange, and VERY frustrating.
