Screen doesn't turn on when power button pressed - AT&T LG Optimus G

After flashing http://forum.xda-developers.com/showthread.php?t=2102986 to my phone (Stable Version, anykernel), my phone no longer responds to the power button.
Actually, it doesn't respond to any buttons (Power/Volume.) I can get the notification LED to light up after I hold down the power button for around 10 seconds with the USB cable plugged in to my computer. However, the screen doesn't turn on, so I can't access download mode.
Any ideas?

Go to device manger and see if it detects your phone as qdlusb or something like that, if so it is hard bricked and needsto be jtag repaired.

Would QHSUSB_DLOAD be the same thing? (That's what shows up when I plug the phone in.)

Yep that's what it says when it is hard bricked. N4 kernels flash by partition number instead of name, or vice versa and it has to be sent in to mobiletechvideos.com to be fixed.

Well shoot. Okay.
My plan as of now is to take it into AT&T tomorrow, and seeing as I'm still under the one year warranty, they should just replace it, right? (I'll just play the stupid card if they ask about rooting/flashing/etc.) Should that be a safe bet?

[Q] Can't get into download, hardware locked?

First of all, I'm not sure if my Vibrant is "hardware-locked" or not - the battery has a date of 8/25/10 printed on it, the sticker behind the battery says "10.09." Either way, I cannot get into download mode. The phone was purchased 1 week ago today. I was simply attempting to disable the voodoo lag fix (using bionix 1.3 rom). I have tried every combination of getting the phone into download mode that I can find - is it possible? I sometimes think it's close to working because during the process a window on my computer pops up that says "hardware not installed correctly" which to me means that I was close. Someone please tell me if it's even possible to get my phone into download mode - it will start up, do the samsung galaxy animation, then go to black screen with the bottom buttons lit up. Thank you for any help you can provide - it makes me ill that I spent $500 on this 1 week ago and am now faced with a complete brick.

yes, when i rooted it, i used 1-click
Try this:
Take battery out
Put battery back in
DO NOT TURN ON PHONE!
Plug in USB
Wait for the green battery screen
Hold vol+ and vol- at the same time
Hold power
When the battery screen goes black, let go power ONLY.
I had a HW locked phone and this method allowed me to get into DL mode--still couldn't get into recovery, but at least I could use ODIN. Was a null point as the phone is bricked and a new one is on its way...
When you say a new one is on its way, did T-Mobile exchange it under warranty even though it was rooted?

If the above doesn't work.
Plug in USB to PC only
Insure Phone is off
Hold in Vol + and -
Plug in USB to Phone Holding Vol + and -
Release Vol + and -
Walla you are in Download Mode
Neither of these methods worked. what are the chances of t-mobile performing an exchange for me if all else fails?
you could try this too, it worked for me.
remove battery and put it back in.
plug in usb
hold vol up, vol down and power button.
when you see the vibrant home screen, keep holding the three buttons until the screen turns dark.
let go the power button and vol up but keep vol down pressed, you should be in download mode.
hope this help.

Since we all seem to have our own variations of this method, I can tell you the one that worked for me 99.99% of the time on the first try when I was stuck at the Phone ! Computer screen.
1) Remove battery
2) Hold Vol - and Power
3) Insert battery while holding these buttons
4) Plug in USB if it works.
Some have reported T-Mo swapping the device due to the inability to access download/recovery mode, but it doesn't seem to be something they will regularly do. Others have been successful by using the inaccurate GPS issue to get a replacement. Specifically by insisting it is not just inaccurate, but downright non-functional.

Yea...I tried relashing the stock rom using ODIN--for 4 hours over and over. It said "successful" in ODIN, but the phone was toast (would go past S boot screen then nothing. Just walked into TMO, said it "just would not do anything" with a feigned puzzled look and after a amateur cursory inspection the rep. just did his thing on the computer and a new phone is being sent to my house via UPS.

Stuck at phone to pc screen + hardware lock phone = RIP

I've tried every possible combination ... literally tried everything and this quote from this thread http://forum.xda-developers.com/showthread.php?t=771247 just comfirmed it to me
METHOD 4: STUCK AT PHONE ! COMPUTER:
(and are not able to use vol+ vol- methods to access downloader/recovery)
CALL TMOBILE AND BEG FOR THEM TO REPLACE UR PHONE..
i cant believe its that easy to mess up your vibrant, my g1 never gave me a problem
did you try:
1. Phone starts OFF
2. Hold volume up + volume down buttons
3. Plug in USB cable
That is how I get into download mode. You don't ever hit the power button and you plug in the USB cable WHILE holding down the volume buttons.

This is the way, no power just volume up an volume down, or just volume down with the same method. Be sure you remove your sd and sim cards also.

I have a hardware locked phone and have been stuck at the phone to computer link screen (a rather nervous place to be, I might say). First you need to take the battery out (to turn the phone off). Then you plug in the USB with the battery out. Then you put the battery in. You need to get the battery charging indicator, and I can't remember if you need to unplug/replug USB for that or not. Then you hold down both volume buttons and the power button. The *second* time you see Vibrant (phone reboots twice) let go the power button. You should end up in download mode.

it resets back to the battery icon.
Basically, im in the exact same situation as El Cipitio. i tried EVERYTHING!!! no luck at all...
Can adb still see your phone? I'm guessing no, but if it can just use "adb reboot downlaod".
Then again.... you guys are aware that the "hardware locked" issue was fixed almost two months ago right? One of the members posted a thread with a zip and the JI6 update also fixed this. There fore if you didn't flash either you should call Tmo, but if you have, then you're just doing it wrong... GL either way.

One other thing to try is to remove the sim and external sd card and try the instructions I posted again. Really, if you get the pc to phone connection icon, you can get it into download mode and use odin to flash.
Dont waste your time fellas with trying to get,into recovery/download mode. If its anything like my hardware locked vibrant there isn't a key combo that will work. Probably thinking that your doing something wrong,YOUR NOT.
Im using my vibrant on att so I didn't consider calling tmobile. I actually called samsung, and after 5min on the phone they agreed to repair/replace for free. They recieved my phone on saturday amd I got it back that following thursday.

This is how I got it to work....
1. Take out the battery
2. Plug the USB into the phone
3. Plug USB into the PC
4. Hold down the Volume up/down + Power button with one hand
5. Put the battery back in with the other hand
6. Wait for the phone2pc icon to flash 2 times and on the second time when the screen goes black release only the POWER BUTTON
7. When you see the digging Android you can let go of the Volume buttons
That is the only way I could get it to work
No, I can't get it into adb mode. The phone bootup screen comes (vibrant, the pink tmobile thing, then galaxy s), but then it goes black. The computer doesn't find anything during this time.
I don't really have time to do the soldering, so i'll try calling samsung. Problem is i live in toronto and bought this thing for cash, so i have no clue what to tell samsung lol. If that doesnt work, i guess soldering it is...
Try this:
unplug, remove battery, remove sim/sd cards
hold down volume control buttons
plug into wall adapter (usb charger - not to computer but to outlet)
pop battery in
Took me a couple tries, but I got my Vibrant into dl mode from nothing but a black screen (I could not register charging, or "phone ! pc" error)

I'm am referencing more to the fact that these phones are not "hardware" locked. Hardware would refer to the volume & power keys not working... When your phone is on they work right?
Like stated before, IF, your phone is "hardware locked" look to either use the script or flash JI6. This way you re-gain functionality of the recovery & dl mode before flashing anything!
Ditto.. i got mine back after flashing without removing the lag fix.. never again... i will wait for froyo.. if that ever happens...
May I ask what bricked you?

The brick, in atleast my case, was from untimely removal of the phone from USB during Download mode of flashing stock kernal via Odin. This method described in the link above worked for me in getting the phone to boot into download mode without the use of the hardware keys (aka hardware locked phones). I also contacted Samsung directly through their Galaxy tech line, and they said I could send it in for free with their shipping label and if they couldn't flash back I could get a replacement, but there was a about a 2 week window I would be looking at without a phone, so I tried the homemade download-boot circuit and it worked perfectly.
THIS IS YOUR FIX!!!
I just did this the other day. If you are still stuck with the phone/!/computer screen do the following:
1.Hold the volume up/down + power button simultaneously
2.The screen will go black / reappear/ then go black again...when this happens, release the power button and continue holding the volume up/down button
3.Welcome back to download mode!
Please Mods, please lock this thread
Please stop waisting everyones time with stupid instructions.
When a phone is "hardware locked" (that is, bad flash/missing the sbin file.....)
YOU CANNOT GET INTO DOWNLOAD MODE OR RECOVERY WITH ANY KEY COMBINATION.
Stop waisting your time trying anything cause its not going to work. And thats a Fact.
Final fix and summary to this thread,
Either call T-mobile or Samsung.
Finish.

Dead vibrant, nothing on screen, no DMode! Help!!

Hi,
I'm going to keep it as short as I can, just bought a vibrant and rooted in a nice way, then I tried to use odin to update from 2.1 to 2.2, it did it but then the screen goes black and it doesn't shows anything and when i say anything I really mean it, no battery when I plug it, and no brick message. Then I discovered that I used the wrong image to try and update it the one for the i9000
note:
i tried to put it on download mode, but as i said before it doesn't do anything is literally dead it, i think I'm going out of options i got no idea what to do anymore, PLZ SOMEONE GIVE ME SOME HOPE!!!
Two options
1) Go to radio shack, spend a few bucks and build a custom USB jig that will get you into download mode. The thread is here somewhere in the forums, search for it.

I did one myself, and tested on a friend captivate, but my vibrant still the same NOTHING!, i mean wtf! the only thing it could have is a software/firmware problem but it seems he completely died on me!! :/
I had a bad cable once and had a odin flash go wrong..
Started out with download mode, but with no luck connecting to pc via 2 diff computers (not realizing it was the cable at the time) I kept messing around with it, sometimes connecting, then Odin screwing up again and eventually got to your point...nothing whatsoever, DEAD
After a while...called TMO and ordered a replacement...but didn't give up, I kept on with cable to phone, then pc...vice versa...battery in/out..and eventually out of nowhere it came back on..no idea how..one thing I do remember is reading to use vol up+down, but for me there was some weird combo where I think i started with up+down, then let go of up(kept holding down, or just used vol down)..can't quite remember...but don't give up..again mine was dead dead dead...somehow she came back...keep trying different things no JIG...
EDIT: Take your micro sd out of the phone and sim card too...that much i do remember...

UnBrickable mod is way better than JTAG. You should check it out. JTAG works once. UnBrickable mod allows software based recovery always and works on a dead brick with no special tools once its applied.
There two videos on the portal now which mention it. I'd like to think people are using it.. after all, this mod doesn't just happen. It takes someone to put in the work to research it... ahem...
option 1
--------
1. remove the sim-card and the memory card
2. remove the battery
3. connect the USB cable to the computer and to the cellphone (still no battery).
4. press on both volume buttons (volume up+volume down)
5.while you press on the buttons enter the battery into the cellphone.
option 2
--------
1. connect the USB cable to the computer and to the cellphone
2. press on both volume buttons (volume up+volume down)
3. press and hold the power button
4. the screen will dim - keep pressing on the buttons (3 of them)
5. the screen will show up the cellphone-computer picture - keep pressing...
6. the screen will dimm again - keep pressing
7. the screen will show up with the vibrant logo
8. leave the buttons - now the cellphone should enter to download mode

It might be the phone is fully bricked and no jig is going to put it into DownLoad mode... If the battery is not charged I don't know if it will go into DL mode with the jig.... I do know you can pull the battery out have your USB cable plugged into your comp and on the phone hold vol+ vol- and then plug the cable into the phone to get into DL mode....

While plugged in, if it heats up closer to the camera than the battery portion of the phone, it's possibly a hard brick.
What I tried from Samsung and ATT tech support before I sent it in for warranty repair:
1. Hold power button down for over 30 s to see if it reboots, or
2. Hold power button + vol up + vol down for 30 s till it reboots, or
3. Hold power button + vol down for 30 s till it reboots, or
4. Remove the battery for 2 min, hold down power button + vol up + vol down buttons, and then put in the battery, or
5. Remove the battery for 2 min, and try step 2, or
6. Remove the battery and try step 2.
Good luck :good:
PS: No questions were asked about rooting/flashing ROMs to me from Samsung before they repaired my phone in warranty. YMMV.

1. Hold power button down for over 30 s to see if it reboots, or
2. Hold power button + vol up + vol down for 30 s till it reboots, or
3. Hold power button + vol down for 30 s till it reboots, or
4. Remove the battery for 2 min, hold down power button + vol up + vol down buttons, and then put in the battery, or
5. Remove the battery for 2 min, and try step 2, or
6. Remove the battery and try step 2.

What is the point of doing this? what would it prove?
1. normal procedure for a BSOD reboot. phone stuck on black screen while on.
2. if off and doing that, will bring recovery mode.
3. nothing
4. minus the power button it should bring you to download mode.
5.pointless
6. pointless.
At&t tech support are retards. They have a list of stuff to do that most of the time does absolutely nothing. Like if your USB port is toast they might have you do a factory reset, which will not do a damn thing.

Well, trying to get OP into download/recovery mode was the point of this thread...
To many techie users at XDA, techs may appear retarded. However, techs have to assume the users who call in don't know much about their phones...hence their boilerplate suggestions.

Good luck :good:
PS: No questions were asked about rooting/flashing ROMs to me from Samsung before they repaired my phone in warranty. YMMV.

The point is that the phone is NOT powering on so the suggestions are to try and get it to turn on and go into download mode at best, at worst get it to turn on and go into ADB. I know the difference between a black screen with phone on on (ADB will work in that case, PC will recognize the device connected) and the phone completely dead.

It might be the phone is fully bricked and no jig is going to put it into DownLoad mode... If the battery is not charged I don't know if it will go into DL mode with the jig.... I do know you can pull the battery out have your USB cable plugged into your comp and on the phone hold vol+ vol- and then plug the cable into the phone to get into DL mode.... Your next step will be a JTAG via MobileTechVideos.com <~~~~ This dude is a BadAss confirmed..... GL

Looks like JTAG service for me.
Nothing else is working.
Thanks for the link and the help.
Just got the phone back from the JTAG service, same behavior.
Contacting them to see if I'm doing something wrong.
Will keep you posted.
Thanks.

Hi, any update on this? I am having the same issue, phone wont go to download mode at all, tried USB jig as well.
Is it worth going to JTAG service, if they dont bring the phone into download mode, do they refund the money?
resolution
My phone is in the same state. Was there ever a resolution to this post?

I have the same problem start out as soft brick went into hard brick over night. Looks like my last hope is JTAG, but if he still couldn't get it to work I don't want to waste my money on it.

My Moto Z died.

i had my phone in my pocket, pulled it out and did some browsing. i changed my zooper widget, clicked the power button to put it to sleep and put it in my pocket. i pulled it out about 5 seconds after i put it in my pocket and the phone is completely dead. doesn´t respond to power button or any of the button combos i have tried (power + vol down / power + vol up) and doesn´t get detected on my pc or in fastboot. i was very gentle with the phone when putting it in my pocket and while pulling it out. i have no idea why this might have happened and it looks brand new on the outside. i was running AOKP and i have had no issues what so ever before. and charging shows no sign of life either, is it a software or hardware problem? and is it fixable in any way? since i live in northern sweden there is no shops or people that do repairs for this phone.

That means your battery died and you're gonna have a hard time connecting it. But it will connect eventually. Connect it to your PC and press the vol down+power button for 2 minutes. If it doesn't pop up then keep trying until it detects it. And when it does.. run the blank flash file and leave the phone in bootloader for atleast 10 minutes it more for the battery to charge, before flashing any rom.

i have tried it on multiple different pc's on multiple different usb ports but still nothing. could i put some books to hold the vol down and power and leave it there or do i need to let go of the buttons every 2 minutes? any tips?

It finally worked for me when I desassembled the entire phone, removed the battery and connected it again. But I won't suggest doing that unless you know what you're doing. And I'm not even sure what worked for me.. it just popped up on my pc after 100,000 attempts :/

I do have warranty from the shop i baught it from (cyberphoto.se). Do you think they could find out that the bootloader is unlocked since the phone is completely dead? Or if they even care?

I work with a phone shop, yes when we send the phones to the service center they will find out if you unlocked the bootloader in official way, even if its bricked. Only on a few dev devices or unsecured/cracked bootloader they won't find out.
thanks for the answers! but i still don't understand why it got bricked... it was functioning perfectly and just straight out of no where just dies? i have read that this has happened on other motorola phones. is it my fault that the phone broke? or is it due to some kind of failure of the phone / motorola?

I today got the phone back from the repair shop. It Said on the website that i would have to pay IF the warranty was void and that they would send me an email so that we could agree on a Price before they repair the phone. But they Never sent me an email and i did not get a Bill with the phone, so i think i got it for free. It says on the note that they changed out the motherboard.
