LG G PRO 2 (D838) Help Needed. - Android Q&A, Help & Troubleshooting

I have a Lg G Pro 2. Few days back it got bricked by its own( a crazy fact). That time it was showing QHSUSB_BULK. I figured it out as 9006. Took the phone to a local service shop. Today I got it back and found that nothing had happened to the phone, except worse. Now it is not detected by PC, only green light blinks for some time if tried to power on. And then everything is black and cold as death.
I think it have been flashed with wrong ROM. Anybody here can guide me with the test points of Lg G Pro 2 (D838 F350) ? So that I can force it to QHSUSB_BULK ? Or any step by step advice to get it up ?
I am in real need of assistance, and thanks in advance for any sort of help. Best Regards.

I would like to mention that the phone indicator blinks for sometime if I try to power it on, as it does on boot, but nothing else is there. No recognition by PC, no presence in Device Manager. Blinks for sometime, stops, again starts blinking... and this goes on at regular short intervals. The area around the camera gets warm after sometime. Everything loops till I pull off battery.
Now, am I missing something ? Is the problem not as deadly as I am thinking ? Is it soft bricked ?

[Q] big trouble with rooting my phone

Hey everyone. This is a quote from androidforums.com it is not my own writing, but this is my exact problem.
"Hey everybody, i recently bought a Sony Ericsson Xperia x10i and thought i should root my phone, using the following tutorial:
Newbies Guide to Rooting X10 and giving you the newest firmware! - xda-developers
So, i was following the steps and after i completed step 5, my phone refused to turn on. At first, the phone would initially vibrate like normal and the LED light would turn green, but then immediately turn off. 5 seconds later, the phone would start constantly vibrating with a black screen and the phone would become unresponsive. To turn it off i had to remove the battery.
I then downloaded the Sony Ericsson PC companion and tried to repair my phone. However, it did no good. Now my phone does the initial vibration, except this time the black screen would lighten up slightly and just stay like that.
I then attempted to charge my phone overnight and when i woke up it just flashes 3 red lights where the LED light is.
could somebody please help me? i only bought my phone 3 days ago and would be a COMPLETE waste of $600 if i was unable to get a replacement phone due to the void of warranty due to rooting.
Is there any way of fixing the phone? If not, is there any way of removing any trace of me rooting or attempting to root the phone (without turning the phone on since i can't) in order to use my warranty?"
My phone has now gone so flat (and doesn't seem to charge) that i can't enter flash mode.. although it was working last night before i went to bed and i did manage to update it using SEUS. But it wont boot up properly. Any ideas? I have noticed that there are a few other people that are having the same problem.. but no one seems to have a solution.
I have also noticed that it runs in a loop. When i plug it in the red light flashes for a while, then attempts to turn on.. and does the black screen for a while. Then it runs out of battery and goes back to the red flashing light. then it repeats.
Hope you can help. Thanks.
Have you tried flashing new firmware with flashtool?
As i tried to explain above.. my phone wont enter flash mode as it is too flat. And it wont charge. when i take it off the charger and try and turn it on. it flashes red three times then a break then three times again and so on.
Any ideas on whats going on?
would it be possible to still claim in on warranty as it wont start properly and wont connect to the computer.

Did you ever get your phone working again?? I have one thats stuck doing the same thing
Same question
Sorry to dig up a dead corpse of a thread, but it never got answered and I have the same problem, only different
No, really it's the same, except not on rebot. My screen goes blue all of its own, when the phone - Lenovo K910 dual sim, running CM 12.1 - is sitting in the desk doing nothing. The first time it happened was when I got an SMS, now it's AFAICT completely random. The screen then goes black sometimes and the blue LED comes on; sometimes it just stays blue. When I force restart, the phone usually wakes up OK, though at the very beginning, yesterday, there were graphical glitches on the screen (coloured bars, different levels of brightness, graphical corruption like you get on your PC when the GPU or memory are dying/glitching.
Since yesterday it has happened about a dozen times. It's got to the point where I am unable to trust the phone (will it throw a fit just as my employer calls me with something important?) and buying a replacement is not something I planned to do for another year, so it'd put a dent in my savings. Can anyone shed any light on this, please? Preferably backed with experience, because in terms of wild guesses I'm Noah's least favourite neighbour (flooded to hell, I mean ).
Thanks in advance!
Same Issue on CM12.1 CricKet Wireless ALCATEL onetouch idol3(5.5) 6045O
I am also experiencing this issue when i power on my Alcatel onetouch idol3(5.5) running CM12.1 when I attempt to power on my device while it is charging. When I do a hard reset however it is able to boot fine. Have you tried to perform a hard reset pressing and holding all buttons at once (Power+Vol Up+Vol Down) until the phone resets...
I'm having the EXACT same problem... Down to the annoying blue LED. I just got the phone (Lenovo K920) 7 months ago. Has anyone found a fix yet?

Nope, the phone's dead and I had to buy a replacement. Needless to say, NOT a Lenovo.

I have a blue screen on my lg android phone,I woke up this morning to find my phone not on, I always leave it on & charge it every night, Well last night it was on & plugged in to charge & when morning came, I find the phone off & try to turn it on & it starts up to a black screen saying lg android & verizon in the right bottom screen & then goes to a blue screen afterwards & then shuts off again. One of my workers I work with, Told me it could be a internal damage inside the phone,But my Mom told me it could be my battery. I read on the internet If your phone has a blue screeen, Try pulling the back & battery out & leave them out of your phone for 10 minutes & after 10 minutes, Put the battery & back on the phone again & try to turn your phone on to see if that helps & if that doesn't work, Then try buying a new battery for it to see if that helps & if that doesn't help, Then you might have to bring it to where you got your phone for them to fix it. I have tried the 10 minute with battery & back off & nothing worked for me. So I was gonna try to buy a new battery to see if that worked.

Huawei Ascend y550 led blinking

Hy everyone.
Cant turn on my Huawei Ascend Y550.When I try to turn on,nothing is happened,only the red,blue and green leds are blinking,one after other.I try to remove the battery but nothing is changed.Please help me.Thank you.
i have the same problem but a little bit different:
it wont start anymore, charging will have the red led burn for 1 min and it goes out again. It wont start in any way, not with the button combos, not with a long press to the power button. I changed the screen already multiple times (my son used it before) and with the present problem i also thought about the battery so i changed that too already. Also inside i cant see anything suspicious on the motherboard. Any idea how i can flash it in this state like a wiko can be flashed? charging without battery isnt working either....
This is an old thread but maybe someone will pick it up for ... us

red blinking led soft brick?

Hi everyone,
I used a month ago my redmi note 4 before the job without worries.
During the morning I wanted to watch something on my phone and no way to turn it on.
Having charged the phone all night, I tell myself that this is not a charging problem.
I tried to restart my phone by pressing the long power button, recovery or fast boot and despite these 3 manipulations there I see only the notification led that lights up red intermittently as the power button is pressed.
I tried to find solutions but no way to find something that would change things.
I used revengeos for a month so it should not come from improper handling.
Can the phone be cracked like that when it worked a month or is it just a fault of the battery? I see only the red notification led when the cable is connected and no sign when it is not.
Battery has been changed and it's the same as before. I've bought an edl to test but no change.
I don't know if I do something wrong but I tested a lot of things found on google search.
Phone isn't recognised correctly in device manager error 43
What do you think of this problem and do you have a solution to offer me?
thank you in advance
Up
Do you know where I can find solutions about this problem?
Thx

Hi guys I would have (not me directly but a friend) a problem that has been literally driving me crazy for 3 days.
A friend gave me the indicated tablet asking me to do a miracle but basically I'm not God. The tablet in question is literally dead. Installed all the drivers, I started RKtool and it is not recognized, even the pc does not give the slightest signal of recognition of a connected device. It doesn't go into download mode, it doesn't go into recovery, it doesn't turn on. I left him in charge all night and nothing at all, shows no signs of life. The red LED while it is charging is there, pressing the reset button vibrates timidly once and then stops ... dead! Anyone have any idea what could have happened? Could anyone help me short-circuit it? I need to know which pins are right. Thanks
