[Q] ADB Way into recovery, bootloop - myTouch 4G Q&A, Help & Troubleshooting

Okay so I flashed a rom and im stuck in a bootloop, but I cant get into recovery to restore a nandroid. My power button receded so as soon as I put in a battery it immediately turns on. But if i go into bootloader, not the power button nor the volume keys will work. So I cant get into recovery that way. Is there any other way like with adb in bootloader? Or am i screwed lol.
Thanks in advance for help, I could really use it.

adb reboot bootloader
adb reboot recovery
It should be obvious what they do. Bootloader won't do you much good without a power button.

if you are in bootloader mode, make sure the phone says FASTBOOT USB somewhere on the screen when connected to the computer.
then type
Code:
fastboot reboot (whatever it is you want to reboot to)
adb only works in recovery or android itself.

Then only thing Im getting is Hboot Usb Plug, not Fastboot Usb
Edit: Okay now I have Fastboot USB showing, but cmd doesnt recognize fastboot, nor will it connect to my device

Just boot the phone in the regular way.
While it boots, in bootanimation or even a bit before that, execute "adb reboot recovery".

All Im getting when I do this is error device not found

Bump.
I can't get it back into fastboot usb either, I think the power button fixed for a second before and selected fastboot.

Do you have a warranty on this phone?
If not, you may want to open it where you can access the power button more easily.
Before you do that though, get it caught in a bootloop and try adb reboot recovery. Reboot and try again at a different point. It should work eventually. Persistence might pay off.

Since you're in the bootloop, your device is connecting and disconnecting. See when it connects (easily recognized Windows "USB device connected" sound), then execute "adb reboot recovery" until the command catches or the phone reboots. Attempt several times.
If it won't work - open the phone and fix the button.

if adb devices does not list device, can device be powered down immediately?

have tried to figure out how to turn off aria when connecting the usb and adb devices does not list device. reboot is the next step (volume up and power) and device always reboots and it seems impossible to hold down volume and power and get back into HBOOT / RECOVERY
question is, is it possible to reboot directly into HBOOT ?
Cancel the loop, reboot the phone, and send "adb reboot bootloader" from the prompt, when the HTC Quietly Brilliant screen appears.

how can I send *any* adb commands when I am unable to see device?
Can you see the phone in adb when it is powered on normally for use? If you can then when the HTC Quietly brilliant screen comes up your computer should be able to connect to the phone through adb. If it does not then you will want to uninstall HTC Sync and re-install it.. ( if you are running Window) make sure you have no anti-virus or malware scanners running/active as those create havoc causing HTC Sync to not install correctly and the drivers necessary for Windows to see the phone properly to not get installed.
Yes, I can see when normally connected but that was not my original question.
I do not have HTC Sync installed, only SDK USB drivers.
Repeat of my original question:
"..how to turn off aria when connecting the usb and adb devices does not list device. reboot is the next step.."
The reason I ask this, is that as I sit on the REBOOT screen and LOOP is running in background, if adb devices does not see phone, when I press power it will automatically reboot and power up all the way to main menu where I have to (again) do a total power shutdown in order to see HBOOT and RECOVERY.
I am trying to get faster to HBOOT and RECOVERY since adb devices is not listing device.
Is that clear now?
Your question was already answered in post 2. Use adb reboot bootloader at the quietly brilliant screen.

wonderful. if only it worked, which it does not since adb (anything) does not work since adb (any command) does not see device

Have you actually tried though?
If you can see your phone in adb devices when it is loaded into Android, then you should be able to send the adb reboot bootloader after you reboot from recovery. The fact that the phone doesn't list during the loop is irrelevant. Once you've rebooted the phone from recovery, and the phone displays the Quietly Brilliant logo, then it has loaded enough to be recognized by the computer, and the adb command will work, and instantly reboot the phone into the hboot screen.
If the command doesn't work, double check to make sure your command prompt is in the right directory with all the right files, try installing Sync, and / or try reinstalling your driver.

Soft Bricked Nexus, fastboot/bootloader non-responsive

So I managed to bricked Nexus last night trying to flash the factory images. It wouldn't flash correctly through the Nexus Root Toolkit, due to the outdated bootloader. I tried to install the 4.2 boot loader through recovery, (as it was flashable). It it didn't work, and I can't boot into recovery as it gets stuck on the splash screen. And of course I can do anything in fastboot because the tablet freezes when I plug in USB. Anything else I can try?
Here's some quick info.
Recovery- TWRP 2.3.3.x
Bootloader- 3.3.4
ROM- CM10.1
Sent from my Rooted Nexus 4
JiG Brick USB
JiG Brick USB might help, but i don't know for sure.
AW: Soft Bricked Nexus, fastboot/bootloader non-responsive
Are you able to boot into boot loader? If yes, you are not bricked. You can flash the factory image and you can flash a new recovery.

So I got back from school today and tried to turn it back on again, and it decided to boot up normally.
This is happening to me. I can boot the Nexus into Fastboot, but as soon as you plug in a USB it freezes and any commands sent from the PC receive only "awaiting device" in response. I can't boot into recovery, it just stays on the Google splash screen and unfortunately the ROM I was trying to install didn't work. Any advice?

Could you please describe a bit in more details what you are doing nd what is freezing?
If you are in bootloader mode, you can send only fastboot commands to your device, nothing else, so I am wondering what is freezing ...

What I mean is that as soon as the USB is plugged in, the bootloader on the Nexus becomes completely unresponsive, I can no longer use the volume buttons to navigate the options or the power button to progress. It appears for all intents and purposes frozen and remains so after the USB is unplugged. Commands sent from ADB while the Nexus is in the bootloader just say "awaiting device" and nothing happens and I can't see the Nexus with ADB Devices.
I may not be using the best terms, I'm assuming the bootloader is the screen where you are given the options of recovery, restart the bootloader, start and so on. That screen becomes completely frozen when the usb cable is plugged in. If I select for it to go to recovery and do not plug in the USB cable, it goes to the google splash screen and the recovery never loads. I've had this Nexus fully rommed before, it has Clockwork Mod Recovery Manager on it and I've had no trouble getting it to load previously.
I'm doing all this because I tried to install a new rom (Paranoid Android Nightlies, latest version) and it did not install properly, upon start it says gapps has stopped and the setup wizard has stopped working - the OS will not load but will just keep repeating these error messages. Thus, I'm trying to either get into recovery or send ADB commands to the tablet to fix it.

1.) When you are in boot loader, adb will not be able to connect to your device, you need to use fastboot instead. This command is part of the SDK and can be called from the command line. Eventually you need to add the directory containing the fastboot executable to your path.
2.) That the buttons do not respond any longer after plugging to USB is very strange.
- What bootloader version is installed on your device?
- What does fastboot devices print on the screen?
- Did you try already with a different USB-port / cable?

All fixed now. It was actually the computer, an issue with the USB, did it on my laptop and was able to fix it pretty quickly. It was you differentiating Fastboot from ADB that got me there though, I tried that on my PC and when it didn't work I then did it on the laptop. Most likely wouldn't have gotten there without you, at least not so quickly. Thank you very much!

ADB Disconnects when phone is in bootloader

So I'm trying to install TWRP through ADB, but every time i reboot my phone into bootloader, adb disconnects and my computer does not recognize it. This problem only recently started. I am on the official version of Nougat. Does anyone else have this problem and know a solution? Thanks!

ADB is only supposed to work while the phone is loaded into the OS or in sideload mode. In bootloader mode, only fastboot will work.
So the correct command to flash the recovery would be:
Code:
fastboot flash recovery recovery-name.img
Example:
Code:
fastboot flash recovery twrp-3.0.2-1-angler.img

sorry my mistake, I meant fastboot. The problem I'm having is that i cannot even enter these commands. It disconnects as soon as it goes into bootloader mode.

Uninstall and then reinstall the drivers by connecting the device. Also, try switching ports.
as weird as it may be, try changing the cable also
I was getting fastboot errors when flashing recovery few days ago, and just by curiosity,I tried with another cable.. it worked with no errors
one more thing.. if you send an adb command to reboot in bootloader, then you have to physically unplug your phone from the computer and plug it back again
only after that, fastboot devices command will show your phone in fastboot mode

Does charging work fine? And did you try using a different computer? Try charging the phone with that cord that you're using. (even though it's really short, see if it charges steadily)

Try updating adb drivers. and make sure you're using data transfer cable, there are many charging cables out there.. those will not read your phone in transfer mode, I've faced this, solved by purchasing new data cable.

nexus 6p not showing on device manager

Hi, my 6p will not show up on my PC. Have tried installing drivers, different PC, different cable but nothing works.
I recently upgraded to android O. I extracted the files from system image and flashed boot image, vendor image, and system. But now when I try to go into recovery it says no command and I lost root access but my bootloader is unlocked. I never flashed the recovery thinking TWRP would stay intact but I guess I was wrong. Normally I would just use ADB and fix it but hence my problem. Is there any way to root without PC or any way I can fix my situation?
Having the same exact issue here, hope someone has a way to fix it.

So your phone will boot into the OS, or not? If so, make sure USB debugging is set to "on" in Developer Settings. Can you put your device in fastboot mode by holding down the volume down button before hitting the power button? The "no command" means you are in (stock) recovery. You then have to hold the power button down while using the volume buttons to navigate. Power button is confirm. Get your phone into bootloader mode and use ADB to flash TWRP again. @meoshe

Yes phone is working fine. Debugging is on. Can't use ADB phone does not get recognized by PC, only charges. Dint even get the pull down notification once I connect usb. Tried changing connection to mtp in developer options also. Nada. Nothing works to fix it. I'm thinking my charging port might have something wrong with it I don't know. I'm stuck not having root atm.

Gotcha. What about the other points? Entering bootloader mode from a powered off state, and that you are in Recovery mode (no command), and navigating thru it with the power+volume buttons?

Yes that works. Thank you. But still can't root phone and can't flash TWRP. Was looking at a root APK but not sure if they will work with O. If I could root then I could install TWRP thru it's app but I need root for that.
You can't root the phone until you have a working custom recovery. Focus on either fastboot flashing or fastboot booting TWRP.img

How do I go about fastboot booting TWRP image?
I can get into bootloader from phone but I can't use a PC.
I did read your OP, but this sounds like a driver issue. There are two drivers that need to be installed first the USB and then fastboot. Since you can boot the device and use it, maybe you should try NRT by Wugfresh to install, test and confirm the drivers are properly installed. Booting or flashing TWRP is just a different command. Instead of fastboot flash recovery twrp.img, you use fastboot boot recovery recovery.img. The NRT toolkit can also either boot or flash a recovery image.
EDIT: Also try "Revoking ADB debugging" and re-enabling @sonysingh1983

Hi, just tried the mtp setting in developer options. Didn't get it the first time but now am able to access internal storage. I have plug sound app from play installed and I get a notification sound when plugging and unplugging. First try there was no sound when changing from charging to mtp. Ok after repeating it. Hope that helps.
Just as a follow up I got my win10 pc to recognize my O flashed nexus. I booted into bootloader after I had updated my sdk and drivers through android studio. It recognized the phone but nothing was happening. I rebooted into the os and the access allow prompt popped up on the phone and adb was able to see it under listed devices.

Bootloader no longer seen in 'adb devices'

After moving to Lineage 14 from stock 21s, I came to realize Android Pay will not work if the bootloader is unlocked.
So I went to go and lock the bootloader (with TWRP and Lineage still installed) and for some reason when I do a "adb devices" the phone is not seen.
I uninstalled the driver, reinstalled.
Tried unplugging, launching ADB, then plugging in..
Plugging in then launching ADB...
Then i put ADB on my wife's laptop (A PC I have never plugged the leeco pro 3 on to), then plugged in for the first time already in fast boot. Still no dice.
Anyone have any ideas?

That is what I am doing, but I am still concerned about the ADB not seeing the phone in fastboot mode. If I have some type of catastrophic issue where i need to restore from fastboot i will be screwed.

If you boot into fastboot mode (Volume Up + Power), does the phone show up in 'fastboot devices'?
If so, then IMHO you should be fine in catastrophic situation.

No, that is the issue, lol
Do you have adb drivers, and did you try completely deleting your device drivers from Device Manager, then reinstalling them by plugging your phone in via USB Debugging? Are you using the platform-tools package? Did you connect via USB Debugging, and did you authorize the computer (the message should pop up on your phone)? I can't fathom why your phone wouldn't be recognized...

Yes to everything, lol
And when I am connected to the phone while in the OS, ADB works fine, shows in when I "ADB devices"
Where'd you get your phone from? Banggood, Geekbuying, Gearbest? Did it come with a vendor ROM? Did it not pass SafetyNet on the original ROM it came with?
Are you following these instructions? Of course, replace the required stock ROM with the one for your version (x720 or x727). So does the issue come up when you reboot the phone via ADB while in the OS?
In any case, try asking on the http://www.leeco.re/ forums as well.
