Hi.
I will try and detail everything about my xda so that I can cover most of the subjects that have been spoken about on this forum.
I am trying to get my xda up and running again, it has not been working for quite some time know so I have not used it in a long while because it stopped working last year and I just left it. Since then I have moved on to another Job and would benefit from the use of the xda.
I have the cradle and the power supply. If I put the battery in the cradle dock it won’t charge, no orange light on the cradle to say it is charging. If I place the xda in the dock or connect it to the power supply then the orange light on the top right hand corner stays on, regardless of whether the battery is in or not. Now I am confident that although you should have a battery in the unit, for the purpose of trying to get it running I am happy to use the power supply. I have followed all the guides to doing a hard reset, such as reset, camera and recorder buttons. For a while nothing was happening, and then suddenly the screen showed a faint image of o2, the network provider I am on. After a few attempts I managed to get it to come on again, and now I have figured a way of how to get it on and what looks like is the problem. If you connect the power supply, only with the battery in the back, the screen comes on with the o2 logo, and those familiar with the brand, you can see the blue oxygen bubble in the water, a blue background. Now, when you connect it straight away, the display lights up, not very bright, but it is noticeable, and then a second later, the orange light comes on to say it is charging, the screen then fades so you can just notice it, and then it goes off and nothing happens. Windows doesn’t see the device through USB, not even for the fraction of time that the unit becomes alive. I am aware the battery is a problem, but I don’t want to be buying a battery for something that it is already broken.
I have taken the unit apart following the guides available on the net, only as far as taking the fascia off and checking the board for damage or loose connections.
Any advice?
Neil.
how about the battery? have you tried a replacement?
I have not tried a replacement battery as I thought the unit could still power up without the battery.
how about checking the little trip-switch under the battery lock notch? if you dont want to have a battery. you should check it if it is on when you put the powersupply.
Just checkup the backlight settings again.

I dropped my HOX and I got another HOX with working mainboard. I replaced it and everything worked except for very faint backlight and flickering. So I disassembled the phone and put it back together again. Now I can't start the phone anymore and the solid red led burns when connected to the charger....after I connect it it flickers one time, very fast. Does anyone have an idea what it could be? So pissed of right now...
Hi, if you don't have any power at all eg no vibration or lights on three bottons at the bottom, it could be that the power connecter is not properly plugged in. follow cabble down from power button, plug is hard to get at unless you unstick power button from cassie.
If you have some power check lcd is working by using a bright light near the screen and closely checking to see if you can see anything, could be backlight not working.
just my 2cents
feel bad for ya!

The cable is connected and I'm afraid the display shows nothing Thanks for your reply.
This might work

Okay, I have experienced the same thing and I'll tell you what I did to fix it. I dropped my HOX after owning for only a few days and the screen was cracked. I ordered a replacement LCD/ screen digitizer part and took it apart. One of the things that I found was that there was adhesive everywhere, including adhesive on the connection to the battery.
After it was taken apart, I attempted to test the new screen. It was then the LED turned solid red and the phone would not power on (even after 10 minutes of charging). What I did was remove the adhesive from he battery connector and disconnected the battery completely. I plugged it back in 10 seconds later and it turned back to flashing green (which is normal because I had several missed texts).
So my solution was just to unplug the battery and it worked just fine. The hardest part about this whole process was putting the cover back on, especially on the side with volume buttons! Hope that helps.
I have exactly the same problem. The difference is that now that I took it off charge, the red light is flickering on and off. I cannot get the display to show! Please please help.
I bought an OEM battery for my Dinc2 from eBay. It didn't look like it was charging, but I left it in there for a few hours. The phone never turned on with the new battery. So I took it out and put the old battery back in (which had a 100% charge)...and now the phone goes to the htc white screen and then goes to black. When I try to turn it back on, nothing. I take the battery back out, and I can turn it on again, but again it only goes to the htc screen and then goes to black.
I can hold power + power down to get into the boot screen. Recovery goes to htc, then black. Factory reset goes to htc, then black.
Is it possible that a bum battery killed my phone?

Sounds like your charging port is broken in my professional opinion. Even if the indicator shows the red light on the top, it does not mean the device is charging. The reason why it turns on and goes black in my opinion is, that it gave you a false charge on the battery when you charged it and won't turn on properly. You're able to go to the Boot menu because it hardly takes any battery life. I'm a cell phone technician, but that's just a guess from what you've told me. It could be a totally different reason. It's a very easy fix if that's the case. The charging port is on a flex cable and you can purchase it for about $5. As long as you know how to open the device properly, you'll be fine. If not seek a professional.

Thanks for your assessment. I guess what I don't understand is how the charging port could break with a discharged/faulty battery? When I first plugged the battery in, it made the orange light blink a few times, which I know is a signal that the battery is really low.

The charging port is really fragile, not much holding it down, especially since its on a flex. I'm not sure if this is against the forum rules or not, you can send it to me if you would like, and I'll be more than happy to fix it for you. Just pay shipping, part and labor. Part and labor $20 and you can use whatever shipping method you would like. Just give me labels to get here and back. You can take it to any repair center near you and they will probably charge you about $50-70. That would decrease the amount of time from the shipping, but it's totally up to you.
Ok, I've owned my M8 for less than 2 weeks and my god what a phone it is!
or was...
Today at half 4pm I was using my phone and was curious as to what happens if you cover one of the cameras and take a photo. I turned my phone round, covered the top camera, turned it back around and accidentally pressed the volume button (i think) and took a photo as the little error it gives about having the top camera covered appeared.
The phone turned off...
I turned it back on, the white 'HTC Powered by Android' screen appeared, then went off again.
I tried again, and again. By the 4th time my 'uuuurgh I CANNOT be bothered for this' mood starts to kick in. However I discovered that it will boot, and work fine, when connected to the mains.
It appears that I have a power issue, however not a hardware power issue. The only times that the phone will now stay on without being plugged in is either in the recovery or HBOOT menu. I've confirmed this by keeping the phone in the HBOOT menu for over an hour on battery. If I boot the phone up whilst plugged in, it will cut out when the power cable is disconnected BUT ONLY when the battery icon goes from charging to discharging. There's a split second between them but it stays on until the icon changes every time.
I phoned HTC, the lady said that I can send it back for repairs but they'll have it 8-10 days. I haven't owned the phone myself for much longer than that!
Tomorrow I'll take it back to carphone warehouse and see what they can do. I don't want to have to look into rooting just yet (if that will sort anything) as I'm happy with it as it is stock. I'm just so gutted. PLUS none of my spare phones fit nano sims.
Anyone have any suggestions at all? I'm open to anything right now and I know that a lot of you reading this are a lot more knowledgeable than myself on the way android works so I'm hoping someone can shed some light. any light
Cheers guys

all will be good your in your 28 days so cpw should hand you a new one take your box and bits with you
Hello all. I recently made this thread where I described the phone, the LG G3 d851 t-mobile variant. randomly rebooting and not turning on without pulling the battery. (http://forum.xda-developers.com/lg-g3/help/d851-randomly-shuts-off-wont-power-t3424458). I deduced it to the replacement battery (supposedly genuine) that I purchased from a seller on ebay. I put my old battery in and everything is fine again, and the seller shipped me another replacement battery (big mistake, i know).
I put in the replacement battery, and a day later the phone shuts down again in the same manner as stated in the previous thread. I pull out the battery and put it back in and.. nothing happens on screen. The LEDS just flash green and blue. I tried plugging it into a charger, just a red LED, no display. If I plug in the phone to a charger without the battery inserted, the backlight activates but nothing whatsoever appears on the screen. I cannot get into the recovery either.
If I let the phone sit for a while, and try to power it on, I see the LG boot screen appear for about 5 seconds. Then the image flickers and fades away to black, and the LED just flashes blue/green.
Am I screwed or is there any way to salvage this phone? I'm desperate for any assistance and I'm totally open to any component level repair you guys recommend (I'm pretty broke :/)
Thanks all!
Current behavior:
Attempt to turn phone on: Blank display, no backlight, blue/green LEDs
Plug phone in with battery in: Blank display, no backlight, red LED
Plug phone without battery in: Blank display, backlight active, red LED
Do any of the above after leaving phone off for a while with battery unplugged: display begins to display the expected image for 5 seconds, then the screen flickers and the image fades until the screen turns black.
I tried the old (working) battery, and no luck either.
[edit] Hopefully solved. please read my latest post for my idiotic but somehow functional solution

It would help if you would say what variant you have (at&t, verizon, sprint). Can you boot into TWRP? If your able to get into bootloader kdz or tot back to stock.

Sorry! I am using the d851 T-mobile model. I can't boot into recovery or anything. the LED just flashes some color but nothing appears on the screen.
Behavior:
Attempt to turn phone on: Blank display, no backlight, blue/green LEDs
Plug phone in with battery in: Blank display, no backlight, red LED
Plug phone without battery in: Blank display, backlight active, red LED
Do any of the above after leaving phone off for a while with battery unplugged: display begins to display the expected image for 5 seconds, then the screen flickers and the image fades until the screen turns black.
Will update the OP
Thank you for the reply.

Possibly bricked plug it into your computer and see what it comes up as.
So strangely enough, I tried heating my phone using the most idiotic method possible by letting it heat in my blanket (I don't have immediate access to a heat gun). The screen began displaying some funky artifacts when attempting to boot with the LG logo but would otherwise revert to the behavior described in the OP (only LED working, no LCD display.).
I let the phone cool for a few hours and I'm actually able to get as far as the dialog box where it asks you whether or not you really want to format, in other words the factory data reset dialog box (when holding vol down + power to get into the recovery) with minimal to no hardware artififacts., and only when I confirm that I do does it crap out and revert to the previously described behavior. But it actually lets me use the vol keys to select an option, so I'm getting a lot further than before.
So this absolutely seems to be a hardware problem. Anywhere you guys suggest I examine before I take a heat gun to the motherboard? Any specific component I should look at?
Thank you guys so much
Take it to certified technician he will fix ur device these phones are dirt cheap nowadays so u will not be charged heavily no more than 50$ worthl
So,
after reading into this more and suspecting loose solder joints (see the various threads about screen flickering problem), I decided to pursue this route and continue trying to heat the logic board.
I'm completely broke and don't have access to a heat gun, and with no other working phone I decided to take some desperate measures. For those of you having a similar problem and reading this, PLEASE DON'T ATTEMPT WHAT I'M ABOUT TO DESCRIBE. THIS IS A HORRIBLE IDEA.
I turned on the phone to get the blue/green LEDs , plugged it into the wall, and wrapped the phone with blankets. I let the phone cook itself for 2 hours.
Yes, just like the infamous xbox 360 "towel trick".
When I went to remove the phone from my makeshift blanket oven, the phone was brutally hot and felt like a stovetop (was painful to touch for the first 30 seconds). The screen was filled with artifacts due to the intense heat.
I carefully removed the battery, let the heat dissipate slowly for a couple minutes, let the phone cool on an AC unit for a another few minutes and turned the phone on.
It worked. Phone boots and haven't had a single problem for over a day.
I guess the problem was cold solder joints after all, and the intense heat was enough to reflow the solder and form a stable enough connection to allow the display to function again.
Even ran a stress test program for an hour with no issues.
Hoping this fix lasts (knock on wood), will report back if I have any issues.
Again, anyone having a similar problem, please don't emulate me. I shouldn't even have to say why this is a bad idea. Get a heat gun, remove the motherboard and heat it that way.
I'm sure applying the proper repair procedure described in this thread http://forum.xda-developers.com/lg-g3/help/screen-flickering-fix-successful-t3397411 would have fixed my problem as well.
So, why did this problem happen in the first place? I'm guessing it has to do with the overheating issues this model of phone has (at least my particular unit). I've been playing a lot of pokemon go, so the phone is running a lot hotter than it used to. The constant high temps (reading upwards of 75c frequently from my cpu) were enough to weaken the solder joints. I also recall dropping the phone a couple times while playing the game, and I guess this was enough to knock the joints out of wack.
I'm currently capping the CPU at 1500mhz and the GPU at 300mhz and the phone is running a lot cooler now. I'm probably going to set the resolution to 1080p, cap the framerate and possibly undervolt, though this might not be necessary.
Thanks for reading and hope this helps someone in the future.
Hi,
Having some issue's with my M9, I replaced the battery as the phone was unusable in that you could charge it to 100% and if turned on, if you unlock the screen it will turn off and act like no juice left in battery, put back on charge and starts at 0% charge then after a short while, jumps up etc, but of no use.
Now with the new battery, it plugs in, red light at the top to indicate charging worked, the charging icon and percentage on screen works, however the phone will not turn on, any ideas what this could be as been googling to no avail, seen different reasons for lack of power, but nothing really in regard to a result of fixing this issue I have now.
Hope someone can help.
Regards,
V4mpire
just as an update, I found out that I had broken the cable going to the power buttons, luckily I have a M9 from when I was in the US and took the sd card tray/power buttons cable and put it in my phone and it works.
