Are you running fastboot as root? Sometimes fastboot does weird things if it's not running as root
moved thread to QA where it belongs......surprised this was in Dev tbh......

[Q] Enabling USB Debugging when caught in boot loop?

Evening all
Hope someone can help. I am a complete novice at anything technical regarding phones/tablets etc and this situation is driving me crazy.
My Nexus 7 (2012 model I believe) recently ran out of battery and after re-charging has been caught in what I believe to be a bootloop. I've tried to google for a straightforward answer that will solve my problem but nothing seems to work. I've done a factory re-set and unlocked the bootloader but do not have usb debugging enabled so appear to be stuck!
Is there anything I can do to solve this before the thing goes out the window?
Please please please help me!!!!
:crying:
As long as you can get to your unlocked bootloader (Power up holding the power and volume down buttons), you can send Fastboot commands to your N7 and restore an operating ROM. Follow the instructions in the second thread in this forum.

Adb devices won't list anything in fastboot mode the command you need is fastboot devices this will confirm if you have a working fastboot connection.
Then you can proceed with flashing a factory image.

Bootloader Problems. please help

I wondered if anyone could help me please?
I am trying to unlock the bootloader on the shield tv 16GB but having a real big problem
in ADB i type adb reboot bootloader but i get no picture on my monitor
i then typed fastboot oem unlock but cannot go any further as i need to see the menu of the shield to authorise the unlock
also when i try to ADB into recovery all i get is the android guy lying on his back with a red triangle
reall stuck now and any help would be gratefully appreciated
Are you absolutely sure you are entering the bootloader? Follow the advice on the first post of : http://forum.xda-developers.com/shield-tv/general/guide-how-to-flash-recovery-image-t3321404
When this is properly done, you should be able to type: fastboot devices and it will show that your Shield TV is connected. Then you can reload the bootloader if necessary as directed in the above thread.
Hope this helps,

Phone can't read ADB in Fastboot/Bootloader Mode. Recognizes when its on though.

I need help figuring this out. My phone pops up and recognizes my computer when it's on, but not when in bootloader mode. I'm trying to flash the new bootloader/radios, but I can't. I've already uninstalled and reinstalled google drivers via SDK. Any suggestions? Yes it responds properly when on when i type "adb devices" just not when in bootloader mode.

Can you be a bit more clear on this? Adb doesn't work in bootloader mode, it isn't meant to, so if you're using adb commands while in the bootloader you're doing the wrong thing. What OS are you using? Exactly what command(s) are you issuing?
How about "fastboot devices"?

I figured it out. It took me a bit to realize adb doesn't work in bootloader. But I installed the correct drivers using max Lee's radio, bootloader, vendor flashing video if anyone needs in the future. Thanks for all you help with Heisenberg. https://www.youtube.com/watch?v=jwEJJIQEt3Y if anyone needs help like I did

Good Point, I know my thread shows up first on Bing whenever I search for my phone and rooting help.
I have another XT and followed all instructions fine but no SuperSU when checking the phone. I tried flashing it twice (the one from the OP in main thread) and nothing. Am I missing a step?
I had installed fine on the first phone. this new one is 100% stock, unlocked bootloader, installed TWRP successfully but no supersu and root checker confirms no root.
Is it B140 or what? If you are missing a step, only you can check that.

If you follow this guide there should be no issue. The rootmygalaxy link should be pretty straightforward at unlocking the bootloader. The guide should be stickied in the OP.

Yes use a different browser. Not working with chrome but working with edge. Go to the same link, it will bring you to EMUI 5.0 page, towards the top click on "download" then on the following page under the search bar click on "unlock bootloader" and it will bring you to the unlocking page. Just confirmed working. Updating the guide and will make a new post for root and twrp

Unlocked the boot loader, now adb/fastboot-15 Second won't work
Hello guys!
I used the 15 Second minimal adb/fastboot package from this site to unlock the boot loader. All seemed to go well, a screen message said success or something like that. It's been over 2 weeks since I had to put the phone down and take care of some other business. Now, after turning the phone off and then back on again when I am ready when I type in "fastboot devices" in the elevated cmd window in the adb directory the only message that comes back is "waiting on the device." Or the equivalent. I have tried what I could find from searching with Google to no avail. I am pretty sure that I am using the same cord, laptop, and everything that worked when I unlocked the boot loader. So, I am at a loss.
My goal originally was to use madvane20's slim downed version of b180 just to get it working again as my almost 2 years old P10 was stolen. I have no money in my budget for a new phone until Feb. 2020. I last talked with him in a series of PM's ending around May of last year, when a reply stated he had to get back to work on the last part of it. I have since seen a post referencing that it was ready in a package that after I had successfully unlocked the boot loader, it would root and install everything. This would have made me a happy guy... but I also noticed a custom ROM is now to be had based on Android 7. In order to get my Bank App's updated version of it's Mobile App to work, I have to install Android v 7 or higher. That's the main app that needs v 7 or better that I use daily. Several times...
But, now when I power up the phone, the first message is, "Your device has been unlocked and cannot be trusted... Press the Power Key now to reboot. Or the device will automatically reboot in 5 seconds." Which it does, the first time walking me through the Set-Up process, now it just boots into Huawei's EMUI 4.1. But, I cannot get adb to find the phone to follow the remainder of the instructions in the guide, "AT&T Huawei Ascend XT H1611 Feb27, 2017 update all things Root and TWRP (guide)"
Nor, can I get into the Recovery mode using the Vol Down/Power Keys.
So, where have I gone wrong or what is my next step? Since the phone can not be found and I can not get into Recovery using the proper keys what do I need to do and how do I do it?
I want to:
Root the phone.
Install the custom ROM I mentioned.
Or, Install an upgrade, if possible, to Android v 7... But,
can not get the phone recognized to get into a Recovery mode (is that right?) to push TWRP to it as well as the other files
it needs and to do whatever the Guides tell me to do.
Specs on the phone:
Model: H1611
Build: H1611C07B180
EMUI v: 4.1
Android v: 6.0.1
Security Patch level: September 1, 2017
Baseband v: 20234
Kernal v: 3.10.49-g03b627c
Sorry for the long post, but I thought it might answer some questions that came to mind before replying back.
Thanks in advance. I'm not here often, but when I am I am always relieved to get out of some jam I have gotten myself into!

mike0921,
What happens if the phone is in normal mode and you type "adb devices" from the PC adb directory command prompt?

I just now found a new(er) USB cable for the phone. I also uninstalled the H1611 under Portable Devices in the Device Manager and rebooted the laptop. Where before, under Events the message was ".... needs further installation..." it now showed a successful install.
At the "adb devices" command, nothing happened, no response. I went and found the directions and explanations for the use of the top 30 commands. It told me to reboot the bootloader. A screen on the phone had me confirm the RSA command. Afterwhich the Fastoot&Recovery Mode screen with the little green Android guy with the message Phone Unlocked, FRP Unlock messages.
I went back to the elevated cmd window and at the adb directory command prompt entered "fastboot devices" and Voila! There were some letters and numbers, five or six spaces and the word "fastboot."
So, am I good to go with the rest of the steps in the guide from here? A question, about him saying to flash the Superuser zip file using TWRP. Is that suppose to already be on my SD card to flash it or can I flash it from my laptop without having to touch the phone or current USB cable? It seems stable but I am a bit gunshy and don't have much faith left in the old equipment I am having to use. A very old, refurbished HP Elitebook 8460P which is running really wonky, a not too new USB cable, the last of five I dug up and have used and finally works but is a bit loose, and Windows 10 1903 etc., which has disappeared all kinds of things I am having to run down) Can I use the "push" command to move the zip file to the SD card? And is that a fastboot function or an adb function? I seem to have read somewhere along the way to this point here that "push" is what I want to do, but powerserge1's Step 7 states to flash it using TWRP. I just want to check. And should questions from here on out be placed in his 184-page thread? I still haven't managed to read the whole thing, it seems to go off in so many other directions that I don't think I need to travel down. But, I will follow your advice.
I want to say a hearty thanks for your help. I was stuck, confused and frustrated at getting no results from Googling and reading for hours and getting nowhere it seemed. And I think I am good to go now.
Thoughts? Suggestions?
Just to be clear, The SuperSU zip file is currently on my laptop in the adb directory. Not on the phone.

And after backing up in TRWP, I just checked the SD card's contents for the backup and saw the SuperSU zip file neatly placed on it as well. Just to be clear!??!
Okay, I somehow screwed this up I think. I was a little distracted by a friend dropping by. After telling her to give me a minute, I looked back at the phone after following Step 6:
Step 6: Confirm phone goes to FASTBOOT & RESCUE mode.
a) fastboot devices (to make sure your device is recognized)
b) fastboot boot TWRP.img (boots TWRP.img from Step 3)
c) The phone will boot into TWRP. Always select Keep Read Only from the first screen every time you go into TWRP.
Peek around a bit if you want to, then use TWRP to backup your stock recovery to external micro SD.
d) Reboot bootloader from inside TWRP to flash this custom recovery image (no adb command this time, you are rebooting to the bootloader from TWRP, you will see this option under "reboot" in TWRP).
e) fastboot flash recovery TWRP.img (now flashes TWRP recovery to the phone)
I then went to Step 7:
Step 7: After phone reboots, get into TWRP recovery repeating Step 6, a and b or hold the power button and volume up button from power-off state, then release when you see Huawei logo.
But now, the phone isn't being recognized again. And when I shut it off, hold Volume Up and Power buttons, I get a screen that asks if I want to: Reboot system now; Wipe data/factory reset; Wipe cache partition. Not the Recovery Screen with the options I got used to seeing in little green characters.
I tried the Reboot system now option and I'm back into the Huawei EMUI with everything appearing unchanged. Powered off, did the Vol Up + Power buttons and am back with the screen offering the three options I mentioned above. And the phone not being recognized after the "Devices" command.
Can you clarify my confusion? What am I doing wrong? Or not doing?
Thanks.
mike
