I'm trying to recover to stock after having a custom ROM for a few days (Cyanogenmod, nothing too fancy).
I was using this guide over on the Nexus dev forum:
http://forum.xda-developers.com/showthread.php?t=2513701
Everything went smoothly until after I flashed the bootunlocker zip to revert the tampered flag back to normal. Then the reboot loop happened.
I've flashed multiple times using both methods to no avail. I also updated the driver on Windows 7.

Try to get into recovery and clear the caches and do a data factory reset. Just hold power down and power at the same time and select recovery.

This works, and it gets me working again. But I would like to reset that flag if possible. It all breaks when I flash the zip found here:

The NexusBootUnlocker script is what is being referenced in the restoration guide.

Did you boot into TWRP to flash the Bootlocker.zip? In cmd type `fastboot boot twrp.img` (or the name you have given it) and reboot?

You can use that script with twrp by booting it as mentiomed above or if u r rooted then u can also use nexus bootunlocker from play store.

Yep. I have done the guide to the letter and followed the video. Nothing.
And it might be worth noting that I am doing this on a red Nexus 5 (the new color). Maybe Google changed something?

No, that doesn`t make a difference. What do you see when you type in cmd: `fastboot oem device-info` with the phone in bootloader?

It shows that the bootloader is locked and the tampering flag is false, just like the tutorial said. However, normal boot results in a loop.

So it worked, now go into recovery and wipe the caches and do a data factory reset and then it should boot normaly.
Don't use the zip then. Unlock the bootloader, root the phone and download bootunlocker app.
Then, reset tamper and lock from the app. Unroot using supersu

Nope, won't boot to recovery. All I have is the adb at the bootloader.
EDIT: Tried unplugging the USB while it was booting. This fixed everything! Thanks for the help!

Ok so today i wanted to root my nexus 5 so i unlocked bootloader via androidSDK slim everything went fine but i did not power up my device yet thet i flash the recovery.img of twrp after that i booted into recovery and for a second it displayed some error i could not see it but it said could not read /e..... or i think so and it reboted itself and started booting android and now i think im stuck in boot loop because its booting up for 10 mins. can someone help me?
So now your Bootloader is unlocked, right?
First boot after unlocking the Bootloader takes time... Wait for 10 more mins and then reboot once again and see whether you can get the OS to bootup...
If you can't, you can either try factory reseting from Bootloader or you can flash a custom recovery and then install a custom rom of your choice.
Or you can also go full stock and start over again by flashing a factory image...

You're supposed to reboot the bootloader before flashing anything.

Again...
Three days ago, I wake up and the Nexus 5 doesn't work. I reboot it, and it is stuck on the Google logo screen. When I went in the TWRP recovery, I couldn't find nothing. Everything erased. Today I received my PC (Ram problems with it) and I tried to flash the factory image 4.4.4, but, when writing the bootloader, the cmd says "remote: flash write failure".
It is happened one month ago, and I had to send it to a LG Center because nothing worked (here the post)
There is something that I can do or I have to send it again to a LG Center? And why diid it happened again?
Again it's probably dead eMMC lol

Have you tried LG Flashtool?
No, I have not understood how to use it..
I have not understood things like the factory version change, and I don't want to brick the phone... there is anything else that I can do?
The phone is already pretty much bricked imo.. Flash write failure means write access to the eMMC has gone kaappuuuttt!
You need to send the device back to LG as already stated by others. It's very unfortunate that this happened to you twice in such a short period.
Sorry for all these posts, but I don't understand this:
I have locked the bootloader, than I unlock it again. When I navigate to start and "click" it, the device opens TWRP recovery and run a process called "Open Recovery" or something like this.
How is it possible? If I unlock the bootloader why the TWRP recovery is always here?

Yes Vin, but how can I send it to LG if I don't reset it?

Locking the bootloading doesn't wipe your recovery. You will need to flash the stock recovery via fastboot to replace twrp. However, I doubt whether you will be able to replace it since the eMMC has gone bad. Anyways, there;'s nothing to loose.. Give it a shot.
I only have to flash the stock recovery in the google factory image 4.4.4 or I have to do particular passages?

1. Unlock the bootloader (if it's locked).
2. Flash stock recovery.img via fastboot.
3. Reboot and use command "fastboot boot twrp.img" //This will boot your device into twrp.
4. Sideload this file in twrp: http://forum.xda-developers.com/attachment.php?attachmentid=2467503&d=1387666907
The above file will reset the tamper flag and lock the bootloader!
When I extract the files from the zip, the boot, system and recovery are dated 12/12/2008... is this normal?
Yes..
Ok, last questions... if I'll flash the zip, I have to use in sideload this: "adb sideload cwm-Nexus.BootUnlocker.zip"?
And why, there is "cwm" in the name? Sorry for all these questions, but I don't want to burn my last hope...
Nexus 5 stuck on 'formatting /data' screen after factory image flashing
Sorry for the long post. I just want to ensure I am providing all relevant history.
I have a Nexus 5 (Hammerhead) 32gb device, stock with no rooting. I mean, I had never done anything special on it ever.
1. Recently I started getting Google Play Store related problems, first 194 error and then couple of days back 495 (I think). After trying switching on/off, clearing cache and some other similar ways to fix this, I decided to do a factory reset :crying:
2. I backed up all my data, and followed the documented steps for factory reset. The phone got stuck on 'erasing'. After waiting for over 24 hours, I finally figured out that this 'erasing' is not going to complete, ever.
3. So I again did some research and figured that I should do a fastboot recovery. Tried that with no difference. Recovery again took me to 'erasing' screen.
4. Some more research and then I decided to flash a factory image using ADB. I was (and still am) a complete newbie, so first I figured out what was ADB and how to get to it. After completing the installation, I found out Nexus 5 factory images. There was no mention of which ones to chose, so I just picked up the latest one.
This is what I really followed:
http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
https://www.youtube.com/watch?v=DRp5jJO34PE
5. Having learnt my lessons, I read the flashing instructions many times and also watched some videos 3-4 times. Once I was confident that no more information was going to be had, and the phone was unlocked (fastboot oem unlock) I went ahead with the flashing. I did it step by step - bootloader, radio and they recovery image. The last one failed.
6. I did some more research and found a method which told me to unzip the last image and flash the component images one by one. I did. Success! However, the phone did not reboot by itself as the guide said it would. So I tried to boot it manually.
7. I did not get the dead android with red exclamation mark. Instead, I got an alive android with gears whirring on its tummy and back. Pressing power + vol-up button told me that this was the 'formatting /data' screen. I am unable to get past this screen. I am supposed to get to a screen where I can wipe data and cache etc. But I cannot get to it.
8. I have tried to wait it out (16 hours) and tried flashing the images again. Ultimately, I end up here.
9. I am unable to find any answers on what to do if stuck on this screen. So this is the end? Is my phone bricked? Is there anything else I can try? Will trying TWRP way help or is that just another way to same failure?
I would appreciate if there is anybody out there who can help me get my phone working again, or point me to a thread which helps me do it. Thanks!
Just wait it took me 5 hours of waiting
Try flashing Android 4.4.4 and see if that will boot. If that does not work try installing a custom recovery like TWRP, and do the wipes from there.

Thanks. I was thinking of trying TWRP anyway. I will try this today.
How does one select which image to flash? Is it always the latest one? In this case, how do I know which one is Android 4.4.4, and why are you recommending this specific one? I had purchased this phone in 2013 Feb (I think). So is there any specific image to be selected or the latest one is always to be picked?

UPDATE: Flashing 4.4.4. did not work. I again got the 'formatting /data' screen again instead of the phone booting up. However, the formatting screen with the android with diamond circling in the tummy also has a blue line below, possibly a progress bar. It is not growing though, just there... sizzling. Pressing power+vol-up buttons shows me that this is 'formatting /data' screen.
Will try custom recovery from TWRP now.

Reboot your phone into bootloader and download latest hammerhead 5.1.1 from Google. Extract everything and then extract the images. First use these commands
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
Then fastboot flash everything including bootloader.
Use this as a guide http://androidforums.com/threads/guide-how-to-flash-a-nexus-factory-image-manually.706533/
Then after finished reboot phone and leave it alone it will boot right up in 5-10 mins no need to go to recovery. In future don't format partitions.

Thank you so much! Your post solved my issue. I wish I had this advice earlier!
First time it did not work, with reboot leading to a blank screen. Next time I following the guide completely, following the order in which different images were flashed. The phone went into boot animation for 5.1.1 and finally booted up, with all 32gb storage available.
Thanks again!

I'm really sorry that you are stuck in this mess. It is normal but more than 1 hour is way too much. I'm not sure about the causes, but you can try two more things and see how it goes. One is to use flash-all.bat script. If that didn't work then you can flash a custom ROM like Chroma and then try flashing the stock ROM.

SO... I did a dumb thing... my friend asked me to install android Q beta on her phone, so I did a sideload.... never checking if it was a verizon phone first... the sideload never errored looked like all was good until the reboot.... operating system corrupt warning... boot to recovery same message... only fastboot with a locked verizon boot loader... did some research looks like I need a firehose... yep.. cant find one... any suggestions or perhaps someone able to help me out?
Did you already try to flash the factory image?
Can be found here: developer.android.com/preview/download#flash (sorry, I cannot post links yet)
First try to flash it without the "-w" flag. If it still does not start, try it with the "-w" flag, but that will delete all data on the phone.
// EDIT if that does not work you might want to head over to the Pixel 3 XL guys here: https://forum.xda-developers.com/pixel-3-xl/how-to/guide-progress-available-t3876849/page10
I can not flash anything in fastboot due to locked bootloader it always says not permitted. booting recovery or OS always says corrupted with the triangle, recovery does NOT show the android guy, just a warning message. fastboot and qualcomm EDL is all I have available.

If you are sure that you can't get into recovery I'd suggest getting an RMA for your friend who has been without the device for 4 or 5 days.
