[Q] Stuck in boot loop after recovery attempt

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!

When you say it won't boot into recovery do you get the dead android with the red exclamation mark? That is recovery just hit vol up

You can't use adb at the bootloader

So I just tried booting it while unplugged from my computer and it worked flawlessly. This bit should be added to future unroot guides.

[Q] Help! problems after instaling twrp 2.7

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.

Flash the factory images from google for the nexus 5. There is a guide in General.
Once your phone boots, flash a recovery

FRP Locked - Stock ROM Corrupt - TWRP Backup Corrupt

[FRD_L09]
Ok, here's the deal.
I recently got myself an unofficial version of TWRP.
Installed it, fine. I then downloaded SuperSu .zip and flashed it.
Tried booting my phone; nothing. OEM was unlocked, and i already made
a twrp backup, before making any changes. I am now stuck with a phone
that wont boot up (nothing happens upon boot), and FRP being locked in bootloader.
I realised some ROMs require a custom version of TWRP, which i cannot flash as FRP is locked
in boot loader, and i dont have access to "USB Debugging" since it wont boot. I tried installing
several different ROMs, including LineAge, CM14 and some others. No luck.
I also went to the manufacturer website (Huawei) to see if they would help me with this issue; no luck. Please help me restore
my device to its original state. Thanks a lot.

It shows up in fastboot, but FRP is locked. I guess FRP is usb debugging, since i cant make any changes.

Nope as above this twrp decrypted successfully internal storage. So nothing wrong with the Pattern ! The data which failed is the partition under /system/data so u might wipe it out :good:

thanks for the help but im not sure if I had twrp after all . no matter what i can't get past the adb device "unauthorized" state. turns out the pixel2 is unique in not supporting usb-c to hdmi - thanks Google. i tried unified toolkit and vysor. next thing i might try is a hammer and send the pulverized phone back to Google.
