My G2 won't boot normaly and is acting very straingly. I did a search of other similar problems people have had, but nothing matches what is happening to mine. It started when I noticed my power button and volume up button stoped working. I assumed it was a glitch and thought a reboot might help. Since the power button wasn't functioning, I pulled the battery to reboot it. That's when it stoped working. When I turn it on normaly with the power button, the screen stays off, it vibrates three times, and the led blinks orange untill I put the battery. If I attempt to boot into recovery with the button combination, it does the same. If I attempt to boot into HBoot, it vibrates five times and the led lights up solid green. Here's where things get realy strange. When I plug the phone into the charger while the phone is off, after about five seconds the phone comes on into the recovery bootloader even though when I boot while holding the buttons it dosn't work. I have the ClockworkMod touch recovery installed. From within the recovery I have full access to everything including ADB with root access. When I select the reboot option from recovery, it does the same thing with the vibrating and the blinking led. I tried the key test in the recovery and I discovered that my volume up button only works intermitently and my power button seems to be working fine. I haven't attempted to flash a new rom yet because I'm assuming it must be something else since I can't even access HBoot, and I'm scared if I touch anything I'll loose access to recovery and ADB as well.
Any advice? Could a damaged volume up button contact cause all this to happen? Should I try flashing it from recovery even though I can't access HBoot?
Thread moved to Q & A section, post in the relevant section next time.

Just tried it. Screen goes black, vibrates three times, and led blinks orange untill I pull the battey. It was a good Idea though, I didn't think to try that myself.
you know what, are these very quick vibrates? you mentioned there is a problem with your volume rocker (sticky keys?) your phone may be trying to get into the jtag/download mode.
not sure how to use this mode on the vision but tell me if this is the same response you get.
take out battery, hold both volume buttons, plug phone into computer.
it should vibrate three times rapidly and computer should look for driver :
Qualcomm CDMA Technolgies MSM driver
not sure where to get the proper driver for the vision but ive used this mode to root other android phones and i know there is a "unbricking project" for various phones that use this mode.
nothing for the vision that i know of though.
but being you have adb access maybe test a few things first like see if anything is accessible from your emmc
type:
Code:
adb shell
dmesg | grep mmc0
and see what happens
edit:
i can replicate you situation by holding volume up while powering on
you have a stuck volume up key, almost 100% just open up phone and clean it out and you should be just fine!
Hey I have an evo that was running madwoz jb rom. like a dummy I try to put it to stock using older ruu. it went through setup and said it was finished. now my evo only turns on to a lit black screen. vibrates once with power button with black lit screen. with power plus vol down it doesn't vibrate just lit black screen. thought it was total brick. but when I press vol down and power I can press up or down a couple time and press power and either restart phone or I think enter recovery but with black lit screen. I say that because when plugged to usb and messing with buttons pressing vol and power after it shows on device manager. also adb devices will recognizes the evo but it has recovery beside the serial number instead of device. in this state I cant even read and copy files through adb. but phone stays blank. I really need help. I have no clue what to do.

Only thing I can think of is putting the stock pc36img.zip file on the sd root folder and trying to get into hboot. If you still cant see the screen check you tube on evo hboot and then at least you can see if you need to hit up or down to confirm installation.
Hello Everyone
TL;DR Screen doesn't come on at all, battery led only flashes while it is rebooting (More details below), and When plugged in to my windows pc, a bunch of "Local Disk Found" pop up, some of the volumes I can access, most I cannot.
I have searched and searched the internet the past 24 for solutions, and have yet to find one. So imma walk you through what led up to the issue, as well what solutions I have tried.
Yesterday while I was trying to update my rom, I ended up getting stuck in what I thought was a boot loop. I then decided to hard reset my phone and go into recovery in hope to try to reinstall the rom. To my surprise, I could not access the internal sd card in the phone. Data was unmounted in the "Mount" settings and I could not what so ever remount it. After this I tried to side load it, but to no avail.
In response to all my attempts to fix the phone at that point, in frustration, I just said "**** it" and went into factory reset in the bootloader. This is where the hard brick happened. At this point, the screen would not come one, and the battery led was not lit when plugged in. I tried letting my phone charge over night and then, tried the "Battery Recalibrate method". I then tried the "Hold Pwr + Volume up for 10 seconds, then Power + volume Down until you access the bootloader"
After that, I then thought that the firmware was corrupted, so I tried to see if I could push an img to the phone, however fastboot does not see the device. I tried RUU, it does not see the device. I tried the HTC Unbrick method by Dexter that required me to install ubuntu and do some things in terminal, that also did not find the device. And here I am stuck. One thing unique to my situation that I have yet seen reported in the countless threads I have searched, is that when I plug my phone to my pc, a large amount of disk drives are found. Most of them are not accessible, but there are a couple that I can go in and see files for. Windows asks me if I want to format the ones I can't access. When hooked to my pc, I tried the the Power + volume button combinations, the only thing that seems to happen off of this is that my phone seems to reboots, and the battery indicator briefly shows.
Anyways, this is all I can remember. Any help would be GREATLY appreciated. I don't really think it is a hardware related issue since my phone does somewhat boot. However it seems it can't get to a bootloader what so ever.
Try holding power and vol up for a long time, like a minute or more. Try with and without charger attached, and after sitting on charger overnight.
If the bootloader is intact, the phone is likely not truly bricked (recoverable). And I don't see how you could have damaged hboot by the actions you mentioned.
What is the phone's original CID (carrier version) and are you s-on or s-off?

Verizon is the carrier version, and I am s-off.
Held vol + up for 5 minutes both with and without the charger. One time with the charger into my computer, and another into the wall. When it was in my pc, I can tell its doing nothing but rebooting over and over by the notification sound, and the constant "Found new disk" notifications I got. However still no luck, no screen turns on, no sign of hboot. I'm hoping to have some luck after leaving it on charge overnight and trying again.

So still nothing after leaving it on charge overnight and I held vol + up for about 5 minutes. Things seem grim.
I think the proper thing to do when you discovered internal storage was not mountable, would have been to use the TWRP option to format internal storage (in Advanced Wipe options).
But now I'm baffled as to what happened that would have rendered the phone unable to boot into fastboot mode. Fastboot won't recognize the device if you can't boot into fastboot mode, which leaves use kinda stuck.
So you didn't try to flash anything during the course of all this troubleshooting?
What you did - "Hold Pwr + Volume up for 10 seconds, then Power + volume Down until you access the bootloader" is totally wrong
I used to get this bunch of local disk pop-up and this is how I get out the problem
Connect the device to pc, you can hear notification sound on pc that device is connected. Ignore all those bunch of local disk pop-up
Press & hold both power button & volume up button until you hear another notification sound that device is disconnected from PC (that's the indication that device is restarted)
Release both power & volume up button and quickly press & hold volume down button (only this one button)
This should get you on bootloader

No, nothing was flashed except the original Rom update that got this snowball rolling (Not saying its the roms fault, most likely mine).

This is the one combination I forgot to mention in the op, sorry for that.
But I have tried this, before and after your post, still no luck.
If it worth mentioning, I can just hold power + down and it still reboots over and over. As well as just power. As a matter of fact, all button combinations reboot the phone over and over.

I thought the screen was dead? If so, how do you know its rebooting?

By it constantly connecting and disconnecting from my pc. If that doesn't mean its rebooting, then I guess I'm mistaken.

Well, it might mean that.
If it in fact is rebooting over and over on its won, simply holding the vol down button for a long time, should put you into bootloader (on the next reboot "cycle"). Again, assuming it is in fact rebooting, and that bootloader is intact.
Hi, it's my first time posting here as I was unable to find a solution looking at similar threads.
Anyways, I was trying to install another ROM on the G4 but I think I messed up deleted everything entirely and got bootlop and reboot. I'm not exactly sure what I was doing as I'm new to these things.
What leads me to believe that this is not a hardware issue (as widely covered) is that during the bootloop, there's a tiny little green android in the middle of the screen with a small 3D box on belly.
When trying to solve this issue, I've tried:
Volume Up + Power to enter Download Mode
Nothing happens - back to the green droid
Volume Up + Power + USB to computer to enter Download Mode
Nothing happens - back to the green droid
Volume Up ONLY + USB to computer to enter Download Mode
Goes in Download Mode for a few seconds, but then goes back to the green droid
Volume Down + Power to enter Recovery Mode
Nothing happens - back to the green droid
Volume Down + Power to enter Hard Reset Mode
Allows me to factory reset, but then back to the green droid and bootloop
Connecting the G4 to the computer to see if phone would be available in device manager -
Not found
Nothing I've tried seems to shake off the little green android.
The phone doesn't connect to the computer at all.
Here's a video: youtu(dot)be/MfnkhZTPOz0
The top left of the G4 says "Bootloader State : Bootloader Unlocked!"
Here's a clearer image of the green android: android-hilfe(dot)de/attachments/2012-09-22-03-41-16-jpg.124036
Any suggestions?

From the thread you gave me it says 'YOU GET QHSUSB BULK MODE IN DEVICE MANAGER THEN INSTALL QUALCOMM DRIVER'.
But unfortunately, when I connect my G4 to the computer, it does not register 'QHSUSB_BULK'. In fact, it does nothing at all. The phone keeps rebooting and the computer does not detect.
So I cannot get either 'QUALCOMM HS-USB 9008' or 'QUALCOMM HS-USB 9006'.

Maybe its the partition table bricked. How did u get in this bootloop ? Few days ago i search half a Day to repair a soft bricked xiaomi. And nothing seems to worknbecoz the partition table was gone. So i have to do it în fastboot mode to write the partition table and flash all the files and after that use usual programe to flash and a new kdz

This thread only introduce hardware methods to enter specific modes, however, if possible, use software method like advanced reboot, adb reboot, magisk reboot, etc. instead for stable entries.
Force reboot: hold both volume- and power keys for 8 seconds (maybe reboot at the 9th second, so hold until the screen changes). This can quit any other mode. Somebody says if you can count time accurately, you can just shutdown the phone instead of rebooting, but I have never succeeded
Normal boot: when your phone is off, hold power key until your phone vibrates (if your phone can boot to system).
Safe mode: during normal booting, when you see the dynamic animation of LG (not static monochromatic logos), hold volume- key until the phone vibrates (you can start holding it even earlier, but make sure holding it until you really enter the safe mode). In this mode, only system apps, default settings and basic functions are enabled. Any reboot quits this mode.
Recovery (stock for master reset or custom twrp): hold volume- and power keys until the initial boot screen of "LG V30" with "powered by Android" displays. (If you have unlocked the bootloader, this screen would display twice, but only the first time is what we are talking about.) Immediately release the power key and hold it again (in other words, pause holding the power button for less than 1 second). Then after the screen changes, release all keys and do further steps according to the instructions displayed.
LG download mode: shutdown your phone first. Hold volume+ key and connect the phone to a working computer via USB. Then the phone should boot to download mode.
Fastboot/Bootloader (if any): similar like the download mode, but use volume- instead of +. However some firmwares may miss this mode. If it works, it should boot to the fastboot interface immediately and you can power off the phone there.
Information screen (I don't know what it's called exactly): shutdown your phone first. Hold all the three of volume+, volume- and power keys, and this will lead you to a screen listing MEID, IMEI and S/N of your phone with corresponding barcodes.
Qualcomm 9008/EDL/QDLoader mode (sometimes even called Qualcomm download mode, but not Android download mode) (mentioned in One way to force shutdown your phone, try this if other modes do not work): connect your phone to a working computer via USB. Hold volume- and power key, around the moment your phone force reboots press volume+ for multiple times (with holding other keys). In device manager on the computer, see if a device named something with "Q" like QUSB_BULK (no proper driver installed) or Qualcomm EDL HS-USB 9008 (proper driver installed) other than anything containing "Android" or "ADB", the phone enters the 9008 mode. If not, unplug the cable and try it again. This can turn off the screen. If you find difficulty to perform it, you can also try other more general methods like test points shortening (see test points lg v30 plus for 9008 mode) or engineering cable (not tested yet).
Yet there is no way to shutdown the phone directly with simple key combination, but you can refer One way to force shutdown your phone to make it if you cannot use regular methods to shut your phone down.
If anything missing, please reply to let me know
