Use adb from bootlooping screen. The command is "adb reboot recovery". Adb is part of android SDK. There are plenty of guides on how to set up adb out there and its easy.

Make sure that you have usb debugging enabled and the driver is installed correctly (with the phone unplugged)

You can run adb from pretty much anywhere. Even if you were stuck in the splashscreen or in the rom.

You don´t to have be in hboot to use adb. You have to be with the phone on normally or from the splash screen itself. If you are in hboot then choose fastboot and try from there but using fastboot devices command instead.
As long as you have not factory reseted the phone the usb debugging drivers will stay in the phone.

USB debugging should always be enabled by default in any custom Rom. The thing that will disable it is doing factory reset from hboot screen. But you can't get there anyways so it should be enabled. Start the phone as normal and let it go to splash screen. Plug into pc and be sure to check that pc sees the phone. If not, unplug phone. Uninstall drivers. Re install drivers and then plug phone back in. From adb type "adb devices". You should see your device. After that run the "adb reboot recovery". If it still doesn't see it plug phone into different port. Preferably one that goes straight into mother board and remove any other USB devices that are plugged in.

any other way to enable it ?
I did a factory reset.
i just installed a new rom.
thank you for trying to help any way/

Go to settings>Applications>development and check USB debugging.
If you're still getting device not recognized, you should reinstall HTC drivers by reinstalling HTC sync. ( if you haven't installed those in the first place, then you won't be able to use adb unless you do)

When you say "factory reset," do you mean that you ran a RUU? Or that you chose "factory reset" in recovery, so you still have a custom ROM installed? If the answer is the latter, you probably have USB Debugging enabled. Just give ADB a try.

Do you have the HTC sync drivers installed? If not, you should be able to find guides for it, like glevitan said.

I have the same problem with HTC Desire HD!
And guess what? It belongs to my wife!!! And I have to give it back to her or I should stay several nights
in the street.... and instead of a pillow I should put a cat or something under my head!
Problem.... Stuck at htc boot screen... not able to enter recovery
I installed 4ext recovery ages ago....
the main problem is that the volume keys ( both up and down ) are broken and neither of them work!
adb restart recovery doesn't work
no device find!
yes I installed all the drivers, and I can boot other phones into recovery
What should I do?
Please help!

How?
I installed the R26.2 successfully, the JB Rom I mean..
Then installed all the tweaks in PIMP my ride successfully again ( I am not a noob.... )
That didn't triggered it...
At the end I was trying to install Int2ext+ and it happened....! I don't know why!
I had done this before on various phones.... I don't know what happened!
The only thing I was able to access so far was HTC BOOT SCREEN! :laugh: and I also
can access a choke hold from my wife soon I guess!
I don't know why these things always happen to her phone... other friends phones are fine when
I change their roms bla bla bla!

Pull the battery and then put it back. And try to boot, pressing power + volume down until you get hboot.

[Q] My G3 is Softbricked - $20 to the first person that can help me fix it!

I'm going crazy here and I need my phone to work!
I have an LG G3 on Verizon.
I rooted it and edited a part of build.prop to change the DPI which got the phone stuck in a boot loop and kept popping up "the process com.android.systemui has stopped.
I tried clearing cache
I tried booting in safe mode
I then did a factory reset
My phone boots up to the Setup Wizard screen but I am STILL getting that systemui error and a com.android.phone and I can't get any further than that screen.
I then tried to use the LG FlashTool to just wipe the entire ROM and replace it with the stock one from Verizon.
This gave me a "Model Information Check FAIL!" error but I DO have the right ROM for my phone. There's only one for the Verizon G3 as far as I can tell
This led me to realizing that there is something in the build.prop that's making LGFlashTool think the proper rom actually isn't right.
I then installed the Android SDK so I can ADB into my phone. but whenever I run "abd devices" nothing shows up in the list.
I was told USB Debugging needs to be turned on in order for this to work, I don't remember if it's turned on or not with my phone and I can't get past the Setup Wizard to edit anything. I wonder if ADB is even running properly on my phone or if these errors are stopping it?
I will gladly paypal someone $20 if they can get this working for me.

Did you tried this?

One of my friends saved his phone by this guide

Download mode - LG PC Suite - Restore update error.
1. Remove battery
2. Boot phone into download mode
3. Open LG PC Suite - restore update error
This method have saved me a few times.

Will adb work in one of the recovery modes even if it wasn't enabled in the full boot mode? If so, start there.

Regarding your USB debugging question, you would have had to turn it on in order to root the phone originally, right? If so I imagine it would still be on unless you unchecked it. You have the proper drivers set up? Anytime I've encountered issues with adb devices not returning any results the issue has been drivers.
Good luck.

I believe I have the proper drivers, I installed drivers and the phone is showing up in device manager as Alright.

Try hooking it up to the lg support tool and select uprade recovery.
Download and install support tool

Plug in phone with phone on.

When you looked for phone in device manager did you change the port to com41? I forgot to do that and got the error in LG Flash Tool

Bro your motherboard is done with take it to service center

Nexus 5x display is scrambled after rolling back from android n developer preview2

Hi All,
Request all to provide any suggestions related to the below issue:
I rolled back from android n preview 2 to android m after which my display is scrambled.I am not able to view any thing on it.
But I am getting calls and able to pick them when I roughly expect the place where I can swipe the dialer right to pick the call.
Few things that I want to highlight is :
1)I had unstable wifi connection while downloading the android m OTA.
2)I removed the unlock bootloader check before rolling back in the developer options.
3)I can also sense that i am able to take screen shots when I am holding the power button and the volume down button based on the sound it normally makes (while capturing screenshots)
I am not able to come to conclusion whether this a hardware issue?(may be i need the replacement of the screen) or can it be due to corrupt ota file update?
Any suggestions would be much appreciated.
thanks

I would first see if flashing the m factory image solves the issue. Then look at hardware.

use "adb reboot bootloader" from command prompt to enter bootloader or if you know the device is off, press power + vol up + vol down for roughly 5sec, thatll get into bootloader. than flash factory image.
or last case scenario use wug fresh toolkit to force flash the image, make sure you select the device fails to boot box (I think that's what its called, the only other one states "device on/normal" <-- so NOT that one)

yes, the adb command will only work if debugging is on. Once in bootlader, use fastboot commands, debugging doesn't matter at that point.

Hi All,
I got the cable ,I had everything to flash the official factory images.But the problem is as mentioned earlier I haven't checked the oem unlock in the developer option and this is not allowing to flash the factory images and fastboot flashing unlock is failing.
Is there any work around for this please?

Not that I'm aware of. Sorry, there is a thread on here that may prove useful that deals with bricked phones with OEM unlocked off. The info there might help you at least get back to stock.

I also want to highlight that,I am getting a black screen on the fastboot mode too,i cant see nothing there..Only way i am able to identify that my device is in fastboot mode is by giving fastboot devices command.
So can this be a software issue?

You might want to look into android screencast.
I don't know if it still works with the latest android releases, but back in kitkat days if I had a screen that wouldn't display I could use screencast and I'd get the framebuffer displaying on the PC. While viewing on PC I could then do touchscreen "guesses" more accurately and presumably you'd be able to enable OEM unlocked bootloader so you can flash factory images.

Help me root this thing PLEASE

So here's the thing: I've just gotten hands on my G4, and I've been sitting here for 6 HOURS straight trying to root it, so I could install TWRP and then install CM13. But it's being F***** IMPOSSIBLE, I've tried loads of guides and tools and all I've got so far was a soft brick (which I managed to fix after a hard reset) and a big headache. Also, is there anyway I could root it on Android 6.0? Because when I tried to root it earlier I had to download this 1.4GB file that would literally take 10 hours to download. NOPE. Either I root it on Android 6.0 or anyone links me someplace else to download it, or it's not gonna happen. So anyway, any good sould would PLEASE explain me step by step how to do this? I used to mod phones a lot back in 2014 but it's been a while since I did it. My G4 is the H815.
