Strange Problem

This morning I woke up and my phone was working fine. I had 2 updates in the market and I hit update all. After that my phone rebooted and it does the Verizon LTE animation and the LG splash screen but it goes into a black screen. While it's in the black screen the phone vibrates and the battery heats up. I tried going into recovery but it did nothing.

Pull the battery fo a few and wait before a reboot?

so you said you went in to recovery and it did nothing? So you couldn't even get recovery to load? and are you stock or rooted with clockworkmod recovery?

I can't even get it into recovery. I hold the volume keys and power buttons and it just does the boot up then black screens.

Just hold down the volume down button, then hold down the power button also. Continue to hold both through the lg splash, then it should be into recovery.

I had the same thing happen to mine 20 days after I got it. I had to have it replaced under the warranty, which means they had to ship it next day air.
I've heard of a few other people with the same problem.

Finally able to get into recovery and wipe data but now phone starts up and its black screen with the status bar across the top. It's acting like it has no home launcher.

Unfortunately you are going to have to get a replacement from VZW. If you are within the 14 day period you can just swap it at the store. otherwise you have to go through the Warranty folks and make sure you have them ship it to you overnight.

Do you have Clockwork installed?
If so, this is an easy fix.
If not, well, it's a little tougher.
The gist of what's happening is easy to find by connecting your phone while it's booting to USB and running "adb logcat" on your desktop.
That will give you the boot logs and the exact reason for what's happening.
If you're running my decrapified ROM, you may want to switch back to the stock ROM. Go to my stock NANDROID thread, download that, put it in the right folder on your SD card, then boot into clockwork and follow the instructions in the stock nandroid thread.
Make sure you clear data also!
No need to call verizon

I tried connecting the phone to the pc and got nothing. computer couldn't even detect it. I called verizon and got the phone swapped under the warranty. First thing I'm doing when I get the phone is putting the recovery on it. Would have made this process much easier.

Yep, having ADB access is a surefire way to get your phone up and running again.
But, just for future reference, LG has a failsafe firmware updater that will always work, no matter what state the phone is in.
It's not super easy to set up, but it will fix a phone no matter how broken the software may be.
There's a thread in the Dev subforum with the files and instructions, but the gist is that it's accessed by holding VOLUP+POWER with usb plugged in, then plugging in the battery.
It's successfully recovered 3 phones so far.
It may not be the easiest way to get the phone back, but it has a 100% success rate

I'm having no luck with my new replacement I got from vzw. I've tried rooting it with S1C using both exploits, I've tried rootwiki's manual method and none of them work for me. Anyone got any tips?

Well... you could always try my "toggle ADB" trick.
Turn usb debugging on, then back off, then on again.
Then follow the rest of the rooting instructions, but skip the whole exploit section.
(Basically, remount /system as rw, push su, chmod su, and push superuser, and install busybox)
Ironically, the phone doesn't actually NEED any exploits at all-- it's pretty unlocked to begin with!

HD7 in bootloop any ideas? PLEASE!

So a guy I know sold a perfect HD7 on ebay and when the guy got it he said it didnt work and sent it back. When my friend got it back he found that it now starts to boot up and fails and reboots only to just start looping. I was wondering if anyone has any idea of how to get it out of the reboot loop. I am android guy so Im not sure how this works or if reboot is the right term or if you can simply flash back to stock or something, but XDA is full of smart people so I figured I would ask.
Thanks!

You are right!
If the phone doesn't boot completely I think the only choice you have is flash the correct stock rom on it.
can you give as a little bit mor information about the phone? (branding, region,...)
can you get into the bootloader menue (hold vol-down when phone powers on)

I had this on my HD7 dont flash the rom before you have tried replacing the battery. I spent days trying this sor t of aproach and nothing worked it just ment i lost my saves on my games once i did get it working.
what would happen in my case was it would show the htc logo then just as it is about to flash the o2 screen it would reboot. I got a test battery for £3 once i found out it was this I replaced it with a nice one.

Can you access the tri-color screen???

Ok so I ordered a new battery and now it boots up and runs great and was about 75% full when I first turned it on so I plugged it into the computer so it could completely charge and I left it for a few hours now I go back and its now at about 25% so basically its not charging for some reason. Also it gets really hot... So from what i can tell the USB port is broken... Also it wont connect to the computer that I can tell. Also yet I can get to the tricolor screen. And now I turned it off and back on and all it does it show the htc screen and then the little black and gray battery icon.

If you have hspal/rspal you may can flash a dft rom....if you want more support in how to flash roms please pm me

Follow every step but got stuck when it trying to flash and stop at 20% just like when I update using LG software. Order new battery hope fixing the problem. My first LG android phone can't return bought it on craigslist

Hopefully the battery will help...good news is if you can connect and start the flash each time it is not bricked...i have not seen this problem posted before so doubt it is hardware...does adb see it...if so i would try to wipe system and data and reflash...i would also pull sim and sd card before flash to see if that helps ?

Replace the battery with new and same problem, my phone doesn't even read my AT&T sim card.
Any button that I can do hard reset?

I had this same problem is your phone not turning on or just not downloading the update? I bricked my phone installing the update and it can be fixed but if you having problems with the connection during update you gotta keep trying it will go through. If it wont turn on at all there is a fix.

This is the problem:
1. I bought new phone on Craigslist running 2.2 and everything working.
2. Connect to PC and set up driver, software etc.. there is an update so I did.
3. Got stuck about 17-20% and message disconnect and re-reconnect etc.. and I did.
4. Ever since I can't t urn it on unless connect to a charger.
5. I will not read SIM card and kept saying reorganized when check on setting and mobile network.
I am stuck here cause tried so many time. Also, phone turn off with full battery charge but next morning when I turn on completely drained. I think software screw up some how during the initial upgrade. Just don't know how to fix it

OK try this take your battery out and plug it into your computer and hold the volume down key until you hear or see your computer recognize it. It should beep a couple times. Be sure to leave your phone off this whole time. Open up your LG support tool. Once it says your connected open the customer support tab. Click on "Recovery Phone." Enter your phones info and click the check button. It should take you through the steps from there. I had the same problem and had also bought it from craigslist. The good news is even if this doesn't fix it, your phone is less than a year old and can be sent to LG for a fix or they'll send you a refurbished phone. They will want a reciept but if you don't have it just tell them you tossed it. Same for the box if you don't have that. They will do it just start getting angry if they give you the run around. I was freaking out just like you LOL. I couldn't find anything on the web and the LG lady was just as stumped as me... I just happened to try this before I sent it in and it worked. Let me know if you have any luck.

As far as the update goes I eventually did get it to work. Just keep trying. I plugged it in to try again one time and it said my phone was already updated. I went and checked and sure enough it was. The visual change isn't dramatic your signal bars turn green and you get some more bloatware like a 3d game converter. The reason for this is the phone has a custom LG UI and will not adopt the gingerbread UI. Don't freak a lot of people insist its not GB but it is. There is a lot more to a OS than the user interface.

Warranty thru LG or at&t? You mind give a little more. I didn't even know LG has a warranty in US?
Sent from my LT26i using xda premium

The warranty is through LG at&t wont do anything for you cause they will know you got it off CL. You'll need your imei and your s/n from under your battery. I wouldn't tell them you got it off CL. The only way this wont work is if the previous owner registered the phone with lg which is unlikely since they didn't even have the GB update. Call 18002430000. Again do not tell them you got it from CL. The phone is under a year old and they will do it for you. If it has to be told that it isn't yours say you had a step brother or friend give it to you. They will want a reciept but you can tell them you tossed it all and your imei Ans s/n will be enough. Also tell them it happened using their support tool. Good luck.

I got panic and it's in local shop if they can repair it but will take it back and try. Thanks.. at least someone here tried to help me... the link flash back to stock ROM didn't work for down load so I can flash it. I even root and flash custom ROM still didn't work now I want to flash it back to stock... if you can just help me a little please

download mode: I got a little confused cause someone told me take battery out connect phone to PC and put battery back. Yours didn't mention anything about put battery back in

Yeah when I did mine it wouldn't turn on at all even when it was plugged in so I think i left my battery in and did it bc it wouldn't respond to anything. I would try to get it to recognize with the battery in but if it turns on after you do plug it in then it will need to be out. You can try to put the battery back in after the computer and the LG support tool recognizes your phone bc after it gets done it reboots. I'm not sure if the battery is needed for it to work but mine was in but you can try it multiple times with it in and out. I freaked out too I had just bought the phone off CL and plugged it in to update and it had the connection failure a couple of times and then poof nothing no vibration no boot screen nothing. The LG people tried getting me to do a hard reset and when that wouldn't work she told me I would have to send it in and that it was still under the manufacturers warranty. I was desperate to say the least so I tried all kinds of combinations. The key is to get your pc to recognize your phone while it is off. If you can do that with the battery in I would try it that way first. If you don't have the box you will need to copy down the phones info, (IMEI and S/N) which is under the battery, for the recovery phone part of the support tool. It worked for me so I hope you have some luck with it. Also I would consider waiting until the ghost call thing gets fixed before you go to gingerbread. If I had known I would have stayed with froyo until they fixed it.

Ok I tried everything and it doesn't work. I now need to flash back to stock rOM using recovery. I need the file Thrill Stock ROM zip file and the link on forum about flash back to stock no longer working

I had the same thing happen to me. U hold down "volume down" and power button, when the phone is off and that will put it into android dfu mode. Now select factory reset and Press menu button.

Volume down for recovery and so on. Volume up for download from tool.
If your doing the recovery method that TheDarkLestat setup then your gonna need to do the software setup and drivers step by step. Assuming you have done that. Remove the battery then plug the USB in and quickly hold down the pwr, and vol UP till it vibrates then let go. Start the loader and place the battery back in while its doing its thing . Then don't touch it till its done.
Only simply way I can think of to repair a soft bricked thrill. As long as it loads to recovery or download then our phone Is fixable. You might be able to politely ask TDL to remote in and provide a fix. He was doing that for a lot of us for a while. Though if your not gonna donate for his time then don't bother lol.

QHSUSB_DLOAD mode??

Hi everybody,
a friend of mine got his HTC One (black) yesterday and rooted it. He flashed a proper custom ROM on it which I and another one of my work buddy use as well without any issues (InsertCoin). No further flashes done, no other custom kernels, no S-Off, no SuperCID. Just unlocked Bootloader and custom ROM.
He let the device run dry yesterday evening so it shut off itself automatically. He put it on his charger, the phone turned on, he did some surfing and installing apps from the market and set up his alarm. The phone charged over night and he was also able to switch off the alarm this morning.
He got ready for work, got into his car and wanted to switch on the screen on the one for some good tunes. But the screen stayed black.
When I arrived at work, he was a little upset and panicked a little. I thought I was able to recover the device.
After plugging it in to my work computer, the device manager just shows a unknown device called "QHSUSB_DLOAD" so I went to google and looked it up..
Weird thing is: QHSUSB_DLOAD wasnt seen yet on the HTC One (M7) as far as I can see it and it was pretty bad on the HTC One S. It means "Qualcom High Speed USB Download Mode" and on the One S as well as on the Nexus 4 this devices showed up after the bootloader got damaged or the device got stuck in that mode for good.
When plugging the device in (USB / Wall charger) the charging LED doesnt turn on at all, the capacitive buttons dont start to blink while holding down the power button as well.
This thing seems to be gone for good.
But aint it the way that we dont even have any access to the bootloader if its not an official update from HTC? Signature check and stuff? Since the device was rooted, no OTA updates were able to arrive at all. He told me that he didnt try to flash anything after we flashed the custom ROM.
Any advice on that?

Did you even try booting the device first thru hboot/bootloader or holding the power button to force a restart? If you did try connecting the device while on QHSUSB_DLOAD and execute a compatible RUU on your PC. RUU uses android's download mode to flash the ROM so it should be repaired by an RUU.

Already tried, no luck. Tells me the device has not been found.

I am sorry to hear that, man, but from the looks of it your friend now has a paperweight. I'd take it to an HTC service center and hear what they have to say regarding this; of course it will no longer be covered under warranty, but maybe they can fix it for you for a price or something.

Are you sure RUU can't find the phone? If it can't then I guess only a JTAG box can fix it so either send it to HTC for repair or have someone who knows JTAG fix it.

I saw this issue on my friend's GS3 once. It was hard bricked and there was no way to recover from what I read (at least on the GS3). I know I saw a thread somewhere here in this forum about the same issue and someone linked to a Sensation thread where there was a way to fix it but I'm not sure if it would apply to the One

Same problem - but the phone magically fixed itself!
I had the exact same problem with my HTC One as described in OP...
My alarm went off in the morning and I set off for work, my battery was low but I thought that I would just charge it when I got to work. I was playing a game (Dungelot) whilst waiting for my bus and was receiving pop up messages about low battery. When it got to 4% left I decided that I would finish the level then close the game down, but as I was just about to finish, the phone went blank...I assumed that I had naturally used up all the battery life and although peeved that I had probably lost my progress in the game, wasn't too bothered.
I got to work and plugged my phone in to charge on my computer. The computer wanted to search for QHSUSB_DLOAD drivers but I thought this must be what it does when my phone isn't switched on and it finds the device. I cancelled the search prompt and tried to switch my phone on...nothing happened.
I tried for the rest of the day, trying to force shut down the bricked phone by holding power in for 30 secs, trying to power into boot mode etc...everything! But the phone would not switch on and the only response I got from it was a little orange LED every now and again and the QHSUSB_DLOAD prompt.
After googling the prompt - I found myself here and REALLY began to sh*t my pants! I've only had the phone less than a month and felt I was tech-savvy enough to flash my phone with a new ROM (Android Revolution HD) to try and get rid of some of the bloatware. I had flashed a new ROM successfully a coupld of weeks before and everything had been fine up that point.
I went home depressed but throught i'd try to plug my phone into a proper mains charger rather than my work's old USB cable (that came with my previous HTC Desire Z) I was going to try a long night of searching the net to try and find a way where I could at least recover the photo's, Zoe's and vids of my new born son but had such a headache that I gave up and went for an early night.
I was woken unexpectedly the next morning by my phone alarm going off! I stopped the alarm and the home just went to Home screen as normal! I don't know how or why these events happened...whether it was the flashed ROM, the game I was playing, the battery running out before the phone could shut down properly, the old USB cable in my work not charging but detecting the device or a combination of all of those, but so far, the phone jumped back into life with the alarm after being charged in the mains all night!
Thought i'd share as it may just help someone else out there who encounters this!

Some phones have miraculously come back from QHSUSB_DLOAD with no explanation of why. Other than that it usually means a hard brick. You can send it to HTC, they will charge you and replace the main board, from what I've heard.

My Solution
Had the same Problem.
My Solution was to Download "HTC One (M7) Toolkit" and force Fastboot.
Pushed Power and Volume Down until Screen was Flashing.
Took about 2 minutes and the Phone was rebooting.
I have no idea what was happening. I have no idea if this helps or works for others. But its worth trying.
Sorry for my bad english.

This is some kind of mode that is enabled when you hold power on button when the device battery is completely drained. i.e. when you try to turn device on it will not boot up (Special I was connected to usb cable via PC to charge my phone NEXUS 4 when I get into this mode). I saw a similar mode where nvflash commands are executed something like APX(can't recall correctly) with Tegra 4 device (that time also I was connected with a usb cable and charging the tablet when it was completely drained!). A simple solution to quit this issue is DO not Panic and let the device get a little charge. After that boot normally with the power button. In case if it didn't try other modes to enter such as recovery or fastboot reboot commands if your device is getting recognised..

QHSUSB DLOAD means its a hard bricked phone, No amount of messing about with it will fix it, Send it to a service centre, it will probable have to have the motherboard replaced..Sorry

My device entered in QHSUSB_DLOAD mode after the 4.4 ota was installed and 30 minutes later, I was able to turn up the phone. It restarted itself like 5 times and then it was normal. Miracle..

What do you mean by "force"? What did you do exactly?

My device wouldn't do anything, and it was in QHSUSB_DLOAD . But when I later pushed the power button for a minute, it worked.

mine spent the night carrying on waking took the charger and the green light for continued access, tried to turn it on but could not. After reading your response, I tried to hold the power button for longer. After 15 seconds the phone rang and the light came on, everything works perfect so far

Today while I was updating firmware phone gone to QHSUSB_DLOAD mode.
I am guessing it's end of road. :crying:

phone vibrates even when switched off! - please help

ok so i got my htc one a couple of days ago and it sees to have a serious problem!
Basically the phone goes through stages of random vibrating every few mins to full on constant vibrating like there is a fan or motor buzzing in there. It even does it if the phone is switched off! Ive just had an episode of it vibrating no stop for 10 mins, didnt make a difference when i switched it off or when i factory reset it!
It seems to overheat or something and only stopped doing it after i had just left it for a while. I have tried to speak with htc about it but they were useless and had no suggestions what soever.
I really need some help here, i bought the phone privately and to all intense purposes it seemed like brand new

No cant exchange it, only option i might have if i cant get the problem ressolved on here would be to send it to htc for repair but can take up to 2 weeks.
when i got the phone it was still on 4.1 and told me update available to 4.2 so i did that. Thats all i have done , apart from unlocking it from 02 using a code.
its almost like on a computer when its being worked hard etc that you here the fan cut in, thats what it seems like except it sounds like the buzz you get when you first start the phone. sometimes it does this just once every few mins or so, other times it will start doing it and not stop...even when switched off.....everything else on the phone seems to work fine

Did the device get wet at some point? Sounds like a hardware problem if a factory reset didn't solve the problem.
There's a slight chance it could be a real bad app or an issue with the rom. Maybe running a stock RUU for your device if you can find it might help.

Pretty sure it hasent got wet .
Would be happy to put stock Rom back on it but not sure how I go about reflashing it .
Don't know if this normal or not but when I did a factory reset I thought the device would be wiped completely, all my pictures and videos etc however when I set it back up again I found some videos on there still that I had downloaded to the phone off the net.
Maybe it's not wiping itself correctly either?

Resetting the device should wipe everything and bring it to the same condition as new.
Go to settings>>Backup & Reset>>Reset phone>>now check "Erase all data", then tap "OK".
If that doesn't work, try to do a factory reset from the bootloader.

Factory reset will wipe the device but leave the contents of the sdcard untouched which explains why your vids are still there

Appreciate the help guys, thankyou
So, is there any benifit to wiping the device completely over and above what I've done allready?
Today the phone has just done the odd sudden vibration as if you were just booting up, around 5 times in total, nowhere near as bad as last night, don't know why that would be.
Would it be possible to reflash standard firmware?
Is so how would I do it. Phone is completley standard and was in 4.1 prior to the ota update to 4.2, could 4.2 be the problem?

IC, but you do have the option to erase the sdcard (storage) from the reset phone menu in settings.

Yes, I see there is a box to tick to wipe everything.
Think it's worth doing?

I'd try it. You can back up your pics and music on your PC via HTC Sync first.

Ok so I have tried it but no joy
Still getting the random buzzing/vibration for no apparent reason.
Could it be a bug with the update to 4.2.2?
Can I go back to 4.1?
I'm at my witts end with this now

Don't think it's a bug with 4.2.2 but a hardware issue.
Couple of other things to try ; download "CID Getter" from the play store, run it and find out your device's CID number. Now search on Google or xda for the RUU for your device's CID number. Download the RUU.exe to your pc, connect your phone to the pc and run the RUU.exe. This will bring the phone back to stock 4.1..
Or you can unlock the bootloader and flash another rom. Step by step instructions can be found on xda
Sorry, don't know of any easy solutions.

thanks for sticking with me on this :good:
I have just followed a a video on here on how to unlock the bootloader and s-off and root - so now good to go
not sure how i put a new firmware on here now though..going to have to do a bit more reading....
i think to start with ill try downloading standard htc 4.1 rom when i can figure out which one it is and how i put it on and then go from there.

ok so just to update this....
last night i have tried the standard google edition rom on my phone and for the first few hours all seemed fine untill 4am this morning when i was woked by the phone doing its random vibrating thing...it was just sat by the side of my bed on charge
Can only think it must be a hardware issue now...but still dont know what or what is triggering it

You tried everything so it's has to be a hardware issue. Maybe the vibration starts when the device gets warm. Sorry we couldn't fix it.

My HTC one has been doing the same thing. Vibrating randomly even when powered down. Brought it back to Sprint and had them order me a new phone. The only way to stop it from vibrating when powered down was to bang it on a hard surface, then it would stop. Crazy!

Vibrating non stop
My HTC One had been vibrating cotinuously too. I kept slapping the upper part of the phone to stop it from vibrating. However, this worked for the initial few days only. Later, it continued to vibrate continuously without stopping at all ! In the night I left the phone in the other room while it was still vibrating and the next morning the phone wouldn't charge at all! Now the phone is not booting/ charging. It is dead! Any leads?
EDIT: I slapped the upper part again, it suddenly woke up from the dead! It is charging now, the LED is red too!! But it is still continuously vibrating. I have left it to charge as of now, but please help with this vibrating problem. Any ideas?

I've had the same issue with my M7 today.
There were no software updates or any new apps lately.
It all emerged when i was pressing the home button (to exit from some app) and at the same time an incomming call started.
I have tried:
switching it off - did not help
Changing volume setting silent\vibe\sound a couple of times - no effect
Soft reset - no help
Hard reset - no help
Slapping with upper side of the phone against my had - helped for some time, the it started again
Seems like hardware issue.
Currently working solution for me:
Switch off the option "Vibrate on keypress" in Settings ==> Sound & notification
UPD: had to turn off all the vibrations
So far so good. Apparently there is some issue with vibe motor, and it just does not stop. I assume that by disabling that option it is not getting started and thus no constant vibe follows.
UPD 2 Fixed:
Issue reoccurred on hitting the device against my palm.
Had to disassemble it, there are a couple of instructions on youtube, i used plastic cards.
Motor was spinning even with a switched off device. Had to unplug and plug the motor a couple of times and it helped.
Turned on all vibrations in settings, no issues so far.
Hope that helps.
