[Q] AT&T Optimus G stuck in black screen - AT&T LG Optimus G

In short: Black screened, computer will detect as QHS_USBLOAD after failed attempt to restore stock rom using teenybin original AFTER failed attempt to flash CWM Recovery from app. Is there anything I can do?
In long: Hello i recently bought an lg optimus g from at and t. It was the first android phone I've ever owned, and after doing a bit of research I decided to root it. After rooting and doing more research I tried to install Clockworkmod Recovery so I could safely install CM. I got a softbrick (I think) and so then I got the phone to Download mode. I then installed LGPNST the right way, with the correct dls and everything, and tried to restore it with teenybin original. LGPNST got to 87%, error, and i waited 5 seconds, unplugged, and tried to boot to factory settings. Now I've got a permanent black screen and my PC will only detect the phone as QHS_USBLOAD, appearing as a device of 4 components on device manager. I've hit a dead end, found only chinese threads dealing with THEIR optimus g. Am I screwed? Sorry for the long read, and appreciate all the help I can get.

Take it back to AT&T. Preferably a device sevice center. I had the same thing happen to my phone when doing an app update through the Play Store. Screen went black. Thought I had SOD but when I hooked it to the computer it gave the same error you are getting. They gave me a replacement no questions asked. The whole process took about 10 minutes.

Do this. Your phone is hard bricked. Only JTAG can fix it, and that's pointless since the device is still under warranty.

[Q] Bricked Thunderbolt? :(

This time I have really f***ed up guys. I really think this time I have actually bricked my Thunderbolt. I was on Bamf Remix 1.63 I believe and everything was running great. I was obviously rooted also. I was bored and decided to flash Protekks Battery Sipper Kernel. Right after I flashed it, the phone would not boot. I pulled the battery and booted up again and it got stuck in a boot loop. So after a few tries I finally got it to boot into the bootloader. I got into recovery and tried to flash a backup and it rebooted in the middle of restoring it. I tried that a few more times. I then let the battery die. Then I charged it up a lot and tried to power it on and got nothing. The screen will not even turn on. When plugged into my computer it sometimes vibrates and my computer detects it and then my computer makes the sound like it was disconnected. I think it is still stuck in the boot loop with the screen off though. BTW the charging light does light up when plugged in. I tried the stock and extended battery to make sure it was not a battery problem. I finally called up Verizon and after I told them it would not turn on he said he is shipping me a free replacement. I told them that after a OTA update the phone would not boot. He warned me that if there is any evidence that the phone was rooted or hacked, I would be charged the retail price for the phone. That is really the only thing I am scared of. Any help would be greatly appreciated!!! Sorry for the long post, I wanted to get in all the details that I could.
Thanks
Adam

Wtf? This isn't Samsung. OP do you bootloop in bootloader? I recommend you go to the irc and give them any info you can.. you will probably end up flashing a stock ruu through the bootloader but first go to irc.

Yeah I did not think we have Odin for HTC phones, and I already have the stock zip file on my MicroSD card but my screen will not turn on at all. I can not get into anything. Any advice?

OK thanks for the replies. Do you think the Verizon warranty center people will actually go to the trouble of getting it to work and then charge me full retail for a new one if they see it is rooted. I already have the stock zip on the SD card so when it does boot up, it will return everything to stock. I have read online that some people have been charged retail because there phones have been rooted but most of them have gotten away with with it..

I think you're almost certainly fine. It's a lot of work and time for big red over one phone. Plus, your etf is less expensive than a replacement device
Sent from my Thunderbolt using XDA Premium App
thanks for the response man. etf= early termination fee? I might not have said in my original post but they are sending me a free replacement device. The rep on the phone specifically said that if they find my phone to be rooted or hacked, that I will be charged around 629$ for the refurb replacement. I really cannot afford that (
Call back and tell em you accidentally dropped it out of moving vehicle and that it was run over 5 times...and that it was raining outside. Then pay your deductible.

I got out of a bootloop on my friend's Insipre 4G (which is very similar to the TB) by mounting the microSD on my computer, and then putting a stock ROM on it. I had to rename the stock ROM PG98IMG (PG05IMG on Thunderbolt), and flash it through the bootloader, but it did work.
Thanks for the post man but the Thunderbolt does not show any signs of life at all besides the flashing orange LED at the top blinking and the computer detecting it on and off every 5 minutes. The stock zip is already on the SD card so when it finally boots up it will flash and hopefully Verizon won't charge me out the @ss for a replacement.
powered on! for a second...
UPDATE: I just had it hooked up to my laptop and it booted on the the white HTC screen and I almost had a heart attaack :O but then it powered off and wont come back on. FML

how long have you had your phone and what hardware revision was it? did you try to run the RUU yet?
i think some people just got a batch of faulty phones because this doesn't seem to affect many.
I highly doubt verizon is going to receive your broken phone and boot it up and it will magically work. The only way it will auto-update is if they boot it into HBOOT. If they somehow just power it on it won't automatically apply anything. Keep that in mind. But I really wouldn't worry too much about it. If they charge you call them and tell them wtf I wasn't rooted. I don't even know what that means lol.
I have had the phone since the very first days it was released. Another slight annoying thing I have had happening prior is the glue on the screen has not been holding it down very well and and I can easily get a nail under it. And it wont let me do anything. I have a Droid X as a backup for now but I miss my beast

that's what im starting to think as htc has since released a revision 2 thunderbolt. i know as i just bought mine a few weeks ago. im wondering if the faulty phones were version 1 phones and have since been fixed. i also do not experience the high battery drain most of you guys do either.

[Q] P769 Bricked without root or other alterations

Hey all, my brother bought an LG P769 for T-Mobile from Walmart, he's never been the type to modify any of his technology, so he used his phone like it was out of the box, no root, no bootloader unlocking, or anything. One night, he gets a security error, his hone turns off, and he can no longer turn it on. The soft buttons don't light up, its not the battery, no moisture damage, and the phone is literally useless. He tried calling LG support, they won't replace it for some reason, as far as I know it was running 4.2, though I'm not sure (he's not here to ask, and I doubt he remembers)
Tried the hard reset, no luck.
Tried to do the offline fastboot method, I installed drivers correctly, and selected option 5, and this time it lights up the soft keys, but it never loads the security error screen, so I can't enter s.w upgrade mode. I've tried pressing 5, waiting the 5 seconds with it plugged in and leaving it plugged in without the battery, leaving it plugged in with the battery, and putting the battery in at different times during the 5 seconds and removing it afterwards, none of them boot to the security error screen.
Tried the LG Mobile Support tool, doesn't recognize my device, even though I installed the drivers directly from the tool.
What do I do?

If you can't return it to Walmart and you are out of other options, you can send it in for repair by starting here: https://www.lg.com/us/support/repair-service/schedule-repair
I recently bricked my rooted P769 trying to update to V20H and ended up sending it for repair. They fixed it within a week and sent it back with a note saying they replaced the flash memory. Same phone, remaining warranty still good, now on V20H. Works fine so far.

Hello
I have a similar problem. What if the computer can recognize the phone? When I plug the phone into the computer, I see OMAP4430 under unknown devices. I heard that a dead phone can be revived through fastboot or kdz updater, is that true? I tried following directions on different forums, but some directions ask that usb debugging is turned on but my phone is dead and I can't do that. When I followed some of the fastboot directions, I was only able to install the driver once and couldn't install it a second time.
yeah, USB debugging was a roadblock for me too.

More than likely the hardware just went out, if all you can use is the unofficial fastboot. If that's not the case maybe, just maybe the x & u images (from lelus fastboot tool) are corrupt. Re-download the fastboot zip and compare (md5 sum) x & u bin files. If one of the images are corrupt it won't boot or respond to anything.

UPDATE: still not working
however, using omap4boot-for_optimus-v1.21 i was able to get the capacitive buttons to light up on the front of the device. haven't noticed anything else as far as success with flashing anything.
the steps i took:
1. installed the fastboot drivers as instructed.
2. I ran omap4boot-for_optimus-v1.21 selected option 5, plugged in my phone, the buttons lit up, and it said to unplug the device and wait for S/W recovery mode, which never popped up.
what do i do?

Dead HTC One qhsusb_dload

Made the mistake of bricking my Att HTC ONE M7. Ive tried everything to revive this damn thing, did loads of research to see if anyone came up with a solution with no luck.
I was restoring my backup phone (Galaxy S2) to convert my mom to an android and get her away from that pile of **** iPhone. I downloaded a philz recovery from the xda app on my ONE for the S2 (which is something I've always had a rule against for this reason).
To make a Long story longer I, for some reason, thought it was for my ONE. Flashed it in recovery (TWRP) "Failed" then I realized what i did. But it failed, I then flashed a bootanimation. "Success"..
Restarted my device but it never came back on. No lights, screen, or response from any combination of buttons.
I guess the recovery flash ,even though it failed, was the nail in the coffin. I just can't believe it died that easy even though it let me flash a bootanimation. Not paying attention just cost me a lot of money and loads of pride.
It shows up qhsusb_dload in device manager. I e-mailed HTC and I'm gonna try a warranty claim. Also talked to someone about Jtag.
If anyone wants to attempt a solution Im game.. I will keep this post up to date with what run around HTC gives if I go that route. If anyone cares...

•Charge the device for at least 10 minutes
•With the device truly OFF while still being plugged into the wall outlet, push in and hold volume up and volume down AND power button, for 2 minutes.
•Let go. Device will boot up, and battery/charging logic are re-calibrated.

Their is a fix now .. I did mine today
QHSUSB_DLOAD Fix
This will fix devices which were bricked due to firmware incompatibility. This can be caused with the way HTC handles the firmware updates in it's m7's OTAs. If you've been flashing from a 3.x firmware to a 5.x firmware via OTA, or manually, you most likely have a device stuck in QHSUSB_DLOAD. This tool is for you
http://forum.xda-developers.com/showthread.php?t=2770684
Prerequisites
the appropriate package for the device
a supported bricked device
a usb cable
fastboot
distro utils: md5sum, strings, tail, grep, unzip ( all included in most linux distros)
some basic linux experience
root access on a linux machine
patience
DISCLAIMER: We do NOT guarantee that this method will work for you, or that it is flawless. We are also not responsible if your phone is completely dead after the procedure, or your house burns down because your phone exploded. You are doing this in YOUR OWN RISK.
Instructions
Boot the linux box and download the appropriate package for the device.
Remove the sim card from the phone. Do not connect yet
Extract the package in your working directory
Open up a terminal and cd to that directory
Run revive.sh as root and connect the device
Code:
sudo ./revive.sh
The procedure is automated. At the end of the unbrick process, you will need to charge the device fully and then flash one of the full firmwares bundled, as pointed from the script. This is crucial to ensure device stability.

The problem with mine is that after I bricked it I sent it to be jtaged. When I got it back it wouldn't unlock to any network. No matter what it asks me for an unlock code.
Maybe I can run this on my phone and restore the emmc that cross checks the modem.???

I sent it to mobile tech videos... I heard good stuff about them but don't send it to them if you want your phone to work again. I don't remember what it cost me but I wish I would have waited for this unbrick method. The jtag process fried my modem or part of my motherboard. Try the unbrick method.

[Q] Samsung Mega sgh -i527 Intermittent touch issues

Hey Guys/Gals!
I (stupidly) jumped into rooting too quickly. It's a great option for really getting the true potential out of your android IMO, but I (having no knowledge of the possible issues of rooting) really messed me up here.
I have a Samsung Mega SGH - I527 and I have no clue what version of android it was originally running.
Basically, one day I was on base with my cell phone in my pocket, and this was about a week after i rooted with a program I believe was called "kingo". I went to pull it out of my pocket, and the screen was not responding to touch. I wasn't doing anything unusual and there aren't any signs of damage of any physical kind. I freaked out on the spot, and realized it must have been the root.
I rebooted the phone, and touch came back. I rejoiced, then freaked out as about 15 - 30 seconds later, the touch went bad again.
It then stayed not working until I rebooted again, and again, and again, until I managed to get to the Factory Reset settings in that little tiny window of time.(a small note while on this subject: not every reboot got me that little bit of time to use the touch, and the amount of time i had to use the touch screen was never consistent from what i could tell.)
From here on out, just troubleshooting steps already tried:
- factory reset on phone in phones UI (did not fix)
- factory reset on phone with bootloader menu (did not fix)
- using Odin 3.07 to put supposed stock firmwareback on the device (did not fix)
- took apart phone to make sure digitizer/lcd cable was seated properly on the motherboard (did not fix)
Any Ideas? just trying to do something that makes this thing NOT a $500 shiny paperweight :'(
feel free to email me @ [email protected] if you have any further questions or info that could help out here!
PS: sorry if this is a repost, I didn't find anything related to this specific topic in forum
I would say your problem is with the hardware and not software. Now what the problem is and how to fix it, I haven't a clue. I would suggest that you contact Samsung.

The only thing is, the phone is /really/ new.. i never abused it, and I'm thinking that its a software issue. I know its possible i broke/failed the hardware, but i really think its the case that the root i did messed it up. Do you know if there are any other more power ful ways to restore the chipset back to originality than using odin to load it back?

[Q] LG G Mini Hard Bricked - Can I Still Fix This?

Tried following this tutorial for CM12 but I didn't read clear enough, bad part on me.

Mine is a LG G2 Mini D618
Did all the steps then when I tapped recovery in quick boot the phone shut down and never turned on again.
It just shows battery logo with red exclamation point in the middle when I press the power button. It doesn't charge on any charger and doesn't allow download mode. When I plug it the red exclamation disappears but it still won't charge.
If anyone can please help me, it would be a very appreciated one.

Hard brick and it's no way back. You have to take it to service to change your phone's motherboard. If you have varandy, and if you are lucky you will not have to pay.

Thank you. I have contacted my local LG Customer Service and they asked me to bring the official receipt and the unit to their service center. I'll just play dumb and hope that they either replace it with a new unit (it would be sweet) or fix the phone.
