[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!

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

Note: after download, replace your latest TWRP .img to overwrite the recovery.img

Flashed TWRP 2.8.7.0 and then flashed super su 2.46. Successfully rooted. Works like a charm.

Try another way here, for entering twrp.
After you flashed the recovery successfully. Do not type the command of "fastboot reboot".
On your phone, press and hold the POWER and UP VOLUME buttons together until you enter the TWRP recovery. (It will power off and boot up recovery)
Note: Do not let it boot to normal system startup. This this case, you need to reflash the recovery via fastboot and follow the steps above again.
After you have root the phone successfully, you can enter the TWRP recovery without flashing via fastboot already.
Hope above help you.

If the touches screen doesn't work, It might be the TWRP recovery issue. You can try flash other version to solve the problem.
Anyway, great to know everything works for you now.

I've this issue.
TWRP is installed but:
- if I boot via [power]+[vol+] I enter in old stock recovery
- if I boot via fastboot using command "fastboot boot recovery.img", TWRP is loaded correctly

Yes very first time after I flashed and entered the TWRP recovery successfully, I need to wait for few minutes and the touchscreen only start working.
Then I have flashed a few other versions of TWRP, I have forgotten which one I have flashed already, my TWRP recovery works immediately without any touchscreen issue.

Need Help. Nexus 5 says google when trying to turn on

I was trying to get the latest twrp '2.8.7.2'. I downloaded it and flashed the img to recovery and nothing seemed to happen so I tried flashing it to boot then I tried to reboot the system. Now when I try to turn it on I get stuck on the Google like it is turning but it just gets stuck. I tried Charging it now when I charge it I get stuck on the battery logo. When I try booting it Booting it into recovery(twrp) I get a black screen. I can tell the Screen is on because of the dim glow it gives off but it is not doing anything. Note: I am some what of a noob when it comes to this stuff, My nexus 5 was running Marshmallow, and I was running the Xtra smooth rom (it is very close to stock). Plz help. I have also just found out that the reason im getting the bootloop is I flashed the wrong version of TWRP need a fix PLZ HELP.

All you have to do is boot into your bootloader (Power + Volume Up + Volume Down at the same time) and flash the stock recovery.
fastboot flash recovery recovery.img
Chances are you flashed an incorrect version of TWRP meant for another phone hence the boot loop.

You dont need recovery, you need bootloader.

Can you please explain to me exactly what to do. thank you. also my bootloader is unlocked. I also can get to fastboot so what is the diffrence between bootloader and fastboot.

Hold down the volume +, volume -, and power button. You'll be taken to a screen with the word START at the top. Now, connect the phone to your Windows computer using the USB cable, open a command prompt and type "fastboot flash recovery nameof twrpfile.img", press the enter key, use the volume button to select recovery, use the power button to enter recovery, press the power button, press volume + button, and you should enter TWRP.

Thank you but I do not own a windows computer

Then look up the respective commands. You flashed twrp over your kernel, you need to flash a proper boot.img (kernel) if you want the phone to boot. Fastboot is ran through bootloader. Flash the proper kernel in bootloader using fastboot.

It might not have been working because I did not enable USB Debuging. :crying:

USB debugging is required for adb commands. With fastboot mode, debugging isn't necessary.

Can't flash TWRP [Oxygen OS & OnePlus recovery]

I am on Oxygen OS (2.1.4) with OnePlus recovery and am trying to install TWRP recovery without any success.
I followed the fastboot method rather than the stupid toolkit
All the steps go through easily with success messages but every time after completion I boot into recovery, it still is OnePlus Recovery and not TWRP
Note - There's not option called "Update Cyanogen recovery" to uncheck under developer options because as I said, I'm on OnePlus Recovery
P.S - I have a Mac and followed the tutorial via terminal under the path ~/Library/Android/sdk/platform-tools

You claimed all the steps went through successfully which can only mean you fastboot flashed TWRP (fastboot flash recovery recovery.img) and it showed success but if you reboot to recovery its still Oxygen recovery.
Your wording was misleading. My advise only applies if the flash was successful.

Do not reboot after flashing twrp, you have to shutdown, off the phone after flashing twrp...If you reboot, stock recovery will overwrite twrp..All you have to do is very simple, fastboot twrp, off the phone, enter twrp ( power + volume down) and done!...twrp will forever be your recovery..

I own a Oneplus one with OxygenOs and I'm trying to change it to lineage but the new flashed TWRP is not showing up when entering at recovery mode.
Where did you enter the code? In your abd path by terminal or at the phone's path by x?

Fastboot, ADB and MiFlash don't recognize device

hello guys,
I wanted to do a clean flash of my poco f2 pro. Installed MiFlash, put the device in fastboot mode (it got recognized) and then klicked flash. the device immediately disappered from miflash and nothing was flashed. I can still boot into rom (Evolution X 4.7) but I have following symptoms:
1. Wifi does not work anymore
2. ADB, Fastboot and MiFlash do not recognize the device
3. TWRP (Chinese One) does not ask for unlock code and shows no sdcard contents (but Its there bc I can boot normally with data) --> DATA Partiton is not found.
4. TWRP Nandroid Backup is gone
I tried multiple Computers, Cables and ADB`s... What is the problem?
Could it be a faulty partition? Which one?
Please help me
