[Q] Phone will not boot to anything--all black screen - AT&T LG Optimus G

I had just installed new kernel from TWRP, and rebooted. Nothing, just straight black screen. I cannot get to recovery or download mode. The battery was about 60% and plugged in when I did the kernel flash. If I hold the power button for a long time, the LED flashes orange about 10 times, then repeats the flashing pattern, only if plugged in to charger. I do not have a small torx to remove the screws and attempt a battery pull. Any ideas? As a note, the phone had been giving me various reboots for no apparent reason.

U prolly flashed a nexus 4 kernel on accident it will give u a hard brick time for JTAG then

Ugh, I was anticipating/dreading hearing that. I wonder if it is worth spending the money to fix. Any idea on the resale on these--working of course?. Thank you.

$99 upgrade to G Pro much better than insurance deductible. Hopefully JTAG can fix my E970 to use as a backup now.

Which JTAG service did you use? MobileTechVideos?

Yes, MobileTechVideos. Phone was received by them Thursday. Still toying with keeping it for backup and canceling my insurance on the E980, assuming Josh can fix the thing.

Update: Received my phone back from MobileTechVideos, and everything works well again. They installed the ROM I had requested, so I am happy with the service and recommend them. Now my only problem is I still prefer the screen on the LGOG over the Pro....

Try a reset or reflash the rom your using. Ice hasn't been released yet officially for the note so you must be on one of the leaks. Try reflashing

Problem is the phone automatically turns off in 10 secs every time even in download mode. I'll keep trying hopefully it will stick. Thanks for the tip though.

Wow that's a new one in me. I thought read someplace that certain roms react this way if the battery get to low and you have to go into cwm and do a cache wipe I think. Sorry that all I got .

If phone is turning off in download mode I doubt it is the ROM installed. Have you tried swapping batteries?
Also the issue seems to ONLY HAPPEN WHEN MOVING THE PHONE! SO I dont think Its a doftware issue. I tried changing battries same issue. It stayed on all NIGHT last night. Then when I go to touch it this morning it restarts.

How about if you leave the charger plugged in? Hopefully you can get the opportunity to get it restored to stock and have it exchanged under warranty.
Edit: stuck power button maybe?

It does it with charger too. But ONLY really does it while moving it
I CANT get it to even turn on now, It will viberate and show samsung and then shut off
I can get it into download mode for a sec and it will flash and turn off
The power button got mashed a little too hard.
If its store bought, its a warranty issue.
If its Craigslist or ebay you have to pull the whole thing apart and reseat the silver button in the case correctly and reassemble.
I've come across a few phones that have this defect.
Hey Ranger, notice you spend a lot of time in what I call the "trenches" in the Q&A and Gen sections providing assistance and guidance. Where I like to hang out and since I have the Note now...and still providing to the Infuse 4G community...
You seem to be a resourceful individual, sir.

Yellow screen of death.

In all of my years using Android I have never seen a full on kernel panic dump screen. I saw it this morning while installing swype beta on my phone running jbsnow's jellybean port.
Should I return my phone for a new one?

Yeah, I think a lot of us rooted users on custom ROM's have at least # it once. I've never heard of it being fatal or that anyone couldn't get the phone out of it. I know it's a scary SOB when it pops up though!

Jank4AU,
PM'd you, sir.
Happened to me when the phone was new all the time, including before I'd rooted it. Gradually happened less and less. Now I can't remember the last time it happened. A few weeks? Over a month? In any case, don't worry about it too much. Mine was the black kernel crash screen though. I think I've only had the yellow screen once.
Sent from my Nexus 7 using Tapatalk HD
I'm pretty sure it happens on that rom because of a glitch in the WiFi part of the kernel. When I was running it I just set the WiFi band to 2.4 only (instead of 5) which fixed it for me.

Happened to me once, scared the crap outta me. Rebooted and never saw it again.
I still can't figure out why the idiot that wrote that error message couldn't tell his up button from his down button.
I wouldn't worry about it. It should not affect anything. I will try to see what it is and fix it in the next version though.

That happens because we are using the n4 aboot. Our hardware differs from the n4 where our up is the opposite key of their up, so it gives that bug.

if it means anything, i got that screen whilst using TheBase.73
and thanks for the explanation.
The demi-god yellow screen? I've gotten that months before using a JB rom.
I've seen it twice, and they happened when I was playing Ingress on my phone while either using WiFi or GPS. I was either rooted+stock or running The Base.
I can honestly say I've never seen this. I got a black screen kernel panic from UVing too far on The Base but that's about it.

Did you find a ROM or fix that works with Ingress on this phone?
I've had it freak out while trying to drop an item or select a xmp to fire.
I usually play on another phone, but I have to send it in for repairs so my Optimus G is my only phone for a week or so and I'd love full functionality in the game.

Power button issue, had something similar. I was able to work it out, but if you have warranty, get them to take care of it.
I had to call at&t and use my insurance. I complained so much that they only made me pay $100 and I get another 12 month warranty....so im good...Thx for the responses

Had that happen to my first note, it did it on and off for a few weeks, then one night it wouldn't turn on anymore, just vibrate. Took it to the local store and luckily had 4 days left in the year warranty, took it to the support center and they gave me a replacement.
Almost got a note 2, guy grabbed on instead of a note and only noticed when the back cover didn't fit. Would of been awesome but I wouldbt of been able to keep it without telling them. Haha

Help needed. DNA wont boot/charge

Hello,
If anyone can save me a couple hundred bucks that I dont have, I would appreciate it.
Im running an S-OFF Unlocked DNA with
This rom - http://forum.xda-dev...d.php?t=2141129
and this kernel - http://forum.xda-dev...d.php?t=2021714
I've been running it without issues for two weeks. Today it just wouldnt turn on. It doesnt accept a charge. Ive gotten the white HTC screen to come on for a second a couple times, and I've gotten it to boot up fully once. But after the screen timed out, it wouldn't come on again.
Any help would be appreciated. Dont have money to buy another phone.
I've tried searching. Most people that have boot issues can at least get to a bootloader or recovery screen. I cannot.
Have you tried letting it charge for a long while? I've heard it takes some times up to fifteen minutes for the charging led to even lit.

Open up the phone and try disconnecting the battery and reconnecting it if you feel comfortable doing that. I suggested that to a user having the same problem as you and that fixed it a couple of days ago.

I personally have never opened up this phone so I wouldn't know. But this is a suggestion that worked for someone else and has also worked when my nexus 7 did a similar act. It wouldn't indicate it was charging and wouldn't turn on but disconnecting the battery and reconnecting it worked for me. I doubt it's something to do with software as you said your set up was working fine for 2 weeks. I'm pretty sure this should fix it for you.

Well, I got the battery disconnected and reconnected. Even though the battery sits under the motherboard, the battery has a thin connector that its accessible without removing anything else. It doesnt appear that my problem has been fixed. I guess I wont ever know, my screwdriver slipped off the screw and connected with a pin on the board and sparked. Pretty sure I just shorted the whole thing.
Claim insurance or warranty. It sounds like a hardware problem if that didn't fix it.

I should mention it was jtagged. Not saying that was the root cause. But the inside of the phone is definitely different than a stock one. Mobiletechvideos.com put a different film on it than the one it came with. Any chance of warranty or insurance is out.
You can still try to claim it. Most of the time they aren't looking inside the phone. Though this really isn't your fault. It sounds like the hardware failed and that is why it wouldn't charge and boot. But we won't know now. I don't know how jtag works but it could have contributed to it.

I believe they would probably just charge you. Not really sure how it works. I have never paid for insurance and I have never broken my phones.

Just to add my 2 cents,
I have sent back phones to verizon and asurion for issues and every phone except one was rooted and never had an issue. I even traded in my thunderboolt towards the dna when it came out (they offered me $72.00) and all i did was uninstall superuser/busybox & titanium backup right in front of the rep and my fiance then handed it right to the guy on the spot. He turned it on, made sure the touch screen worked & then said ok, you get full trade in price.
As for the other phones that I sent in, droid eris, incredible and 2 samsung, all with one issue or another, never once did they charge me or call or anything. Got the new phone next day, sent the old one in and thats it. I have never had an issue.
Now I know this may not have happened for every one but I think if you just send it in via mail and not have an instore rep look at it, you will never have an issue. I think if an in store rep sees an issue and realize its rooted, they may flag it in case it goes in for verizon replacement or asurion replacement but just a normal send in should not cause an issue.

any way to fix dna (fix jtag only)

ok i just had a fatal error happen, as i was running the 1.15 RUU (because i was having issues) status bar got to 17% the my asus computer rebooted to complete some updates that i had no idea were installing. mMy phone now does nothing at all.. no bootloader, no led when pluged in, i mean nothing. is there anything that i can do besides sell for dirt cheap,,, thanks
i guess with 100 views and no comments, that im screwed.. any developers out there need parts or a dead phone to tinker with ?.. i will be very slow to respond since i have no phone.. smdh

Yeah JTAG is the best way to go. It sucks to lose all the data but at least you have a working phone. You 're only entitled of 2 claims within 12 months on Insurance. If you use them both you'll be dropped from the Insurance coverage for a year; no matter if you purchase a brand new device. So I'd suggest you save them
