Phone Doesn't Charge or Boot - LG Optimus G Pro

Hi All,
Recently I have been having multiple problems related to My LG G Pro E98X Indian Version.
1) Battery sometimes drops suddenly. ex From 92% to 40 % in a second. Replaced battery with New one still issue persisted.
2) Charging was too slow, hence tried a New LG Charger and another Samsung 2.1A charger to charge, Seen some improvement.
3) Now 3 Days Before, After charging it for some time it heated and Few time later, it Shut down. And hence from that day neither it is booting nor it is charging.
4) When i connect the phone to Wall charger or USB Charger , it flashes front White LED continuously. When i Press Volume Up+Down+ power my PC detects it as a USB drive for 1 Second and disconnects.
5) Volume Down + Menu + Power Button or Hard Reset also not working.
Suggest any Solution.
Thank you Very Much in Advance, Hope it will be solved.
Regards
Pratik

[POSSIBLE FIX] Flashing red light - dead phone/inferior USB cables

Today I had my One X happily connected to my pc, just transferring some files over by USB. Then when I wanted to disconnect it, it showed a lot of 'not getting enough current to charge and operate at the same time' messages. Dismissed them all, though it was time to put it on the wall charger, seen it's critical battery status.
Once I disconnected the phone, it immediately powered off and would not come back to life again. It was, however, greeting me with a flashing red light while on the wall charger. No matter what I tried (bootloader, long hold power button, charge it for some time), it remained completely dead.
Now I did get some new micro usb cables from eBay. Very cheap ones. Now I think these are the culprit. Apparently, while in file transfer mode, these cables were unable to provide sufficient current, causing the phone to drain the battery completely. Once I wanted to charge it, it couldn't boot to charger mode due to the battery being completely empty.
Hooking up with the original HTC cable again, it still showed the red flashing light. Exact same behavior. Until I (for the heck of it) tried to bash the power button quickly. It suddenly came back to life again and started charging again through PC.
If you find yourself in the same situation with bad USB leads (something to do with resistance of the cable?) or a red blinking light, try tapping the power button quickly instead of trying to boot into recovery mode. It might save you a postal return and a week or 3. Or your ass, if you rooted it before it stopped charging.
When I had my sensation I had this every now and then. I had to remove the battery to get it to work.. Nice to know that there appears to be something I can do to sort this out if I get this now

It was mentioned that the flashing red (or orange?) meant that the temp was too high.
Just let it cool down, and it will come back.
It definitely wasn't hot. Also, it wasn't flashing orange. Just slowly red.

Your quite right. Overheating on charge flashes red then green. Never seen a flashing red so can't comment

flashing orange - low battery
flashing red - very low battery
It could well be the battery level is considered too low to operate. So to protect the circuit and the battery, the device is not allowed to turn on until it is sufficiently charged.
This is currently (no pun intended) happening to my one x, left it plugged into my pc via the htc usb and got flashing red light after a couple of minutes, after a couple of minutes more it stopped flashing and became a solid red light (a sign it is charging from v low battery from m experience) pressed the power button and voilĂ  its come back on. I can't believe htc would let the device get to such a critical state of battery before powering down, can anyone enlighten me as to why it would do this?
(thinking about it i was showcasing the handset to my apple touting buddy and had 3 pretty heavy apps running, it was a couple of hours after i noticed it had killed itself so i'm guessing they were still draining away the power from the background??)
I'm having the same problem. My phone was off when i got home and it wouldn't turn on (I assume the battery was dead). When I put it on the wall charger the red the red light didn't turn on and my phone wouldn't boot. I tried several chargers and cables and also tried to connect it to my pc. After leaving the phone for a few hours (unplugged) i tried to connect it to my pc again and i got the blinking red light. A few minutes later I decided to plug it into the wall and the red light turned on and now it is working normally.
anyone got an idea why it didn't charge at first?
agree chaging cable fixed my flashing red light problem
Poor quality charging/data cable
A poor quality charging/data cable will also impact the ability to charge the HOX in your car. I have two cars, in one I was using an old Blackberry cable and Griffin charge adapter (1amp output) to charge the phone whilst using Car Dock and navigation software. After trial and error I got the screen brightness correct and the phone charged satisfactorily. I say satisfactorily because I still think any electronic device which is connected to an external power supply of sufficient electrical current should operate and charge at full spec. In my other car (1996 Land Rover Discovery) I was using a cheap ebay charging/data cable. Using the same apps and screen brightness the HOX would lose all charge over about a two hour period. With the same Blackberry cable used in my other car, no problem. Hence the cheap ebay cables are now in the bin.

The HTC-cable isn't that good too. I use a Nokia-charger to charge my HOX. Charging is much quicker. Maybe the HTC--charger (and cable) was crappy but i never touch them, i use the Nokia charger and dito USB cable.
Thank you!

thank you! Thank you! That cheap usb was totally the problem!
Small update.
This problem just happened to me. 1 cord gave me flashing red while plugged into the wall and pc. I switched to my other cable and its charging and functioning normally. Cord was the problem.
I had a similar issue with my one x.
It discharged completely, then when I went to charge it I just got the red blinking light for ages. I left it charging overnight thinking the battery was so low it needed a while to charge enough to be able to switch on.
But in the morning it was still flashing and the phone was very hot, so I thought the battery was blown.
So I came on here and saw a suggestion about holding the power button and the volume down button. It went to the boot menu and said there was not enough power for a factory reset or something, so I selected recovery. I then got a warning icon and the phone switched off again, but this time with a solid red light. A
After a while I was able to turn it back on again.
Hope this helps.
Wellllll
I have the HTC One VX. I know this isn't in the same topic, but since I found the thing that helped/worked here, I thought I should share my experience. So I bought my new phone on Sunday, so it is roughly 5 days old...not even a full week. I charged the phone before I went to bed to roughly 80%. I made sure all apps and what not were turned off and pressed the lock button. I woke up in the morning and checked my phone to see what time it was. Had 78% battery left. I left it on my dresser for roughly 2 hours and when I got back from class, I grabbed my phone to check if I had any messages.
The phone didn't turn on and I didn't even get the flashing orange/red light. So I tried charging it and nothing. I changed wires and nothing. I frantically searched the internet and stumbled upon this forum/thread. I tapped the power button at least 15 times consecutively and the phone barely flashed orange. I tried to plug it in again and rapidly pressed the power button 10 more times and the screen finally turned on. It started charging and I checked the battery life. Somehow, in 2 hours my phone drained itself of 78% battery life when it was on the lock screen (its also set to lock after 15 seconds of inactivity) to the point where it couldn't even turn on.
The phone/battery was not even warm/hot or w/e. It had not touched any water. No idea what caused the immense power drain, but glad it is working. Thank you so much for this help
woops, wrong thread
It happens to me allso in this morning, in my opinion is like this: The phone is turning off when basicly you have a little bit batt (lets say something around 5% max) and its turning off to protect data and is showing to you batt empty. Then it cames a user with a charger connected to a power supply (house charger,car charger or directly to pc's usb). You must use a good usb to micro-usb charger (the original ones are't good usb cables) try to use a Nokia usb to micro-usb cable, This was the first problem most usualy. The second one is to pay a HUGE attention to UC, don't uc'it so much because then the charger board will not charge your batt so well. Keep yours HOX safe and anjoy it. Have a nice day boys and girls.

one problem with htc one m8

hi all i just got htc one m8 second hand used... lollipop 5.0.1 was already pre installed . so i did a factory reset charged my phone but i noticed a problem with phone that when i restart my device the phone do not automatically pick network signals i have to turn on the Aeroplane mode and then turn it off then my phone captures signals... i have restarted my times but the same problem occurs every time... what to do??
And one more thing to ask please.... the original htc charger i got with phone which is 1.5A charger is too slow to charge it is saying me that 3.5 hours until full it is charging 1% in 3 minutes so i tried another Samsung 2 A charger and that is much fast its charging 1% in one minute so my question is that can i use 2A charger for my phone? will there be any problems or is it effect battery??
I also got a HTC M8 used and when I connected to the charger it was taking 3+ hrs to charge. However, after reading about charging time problems, I did some power cycles (turn off phone, connect to charger for 10-15min, then press Vol up + Vol down + power button. Keep them pressed for a good 2min. The phone will boot and reboot during that time. Then let it boot normally and let it charge). After I did this, my charging went from 3+ hrs to 1hr 30 min with the same charger (I charged it from 5% to full). Hopefully this will help charging time, if not, try different charger / USB cable.
As for wifi problems, make sure you are running Lollipop firmware for your ROM as this is usually a culprot with WIFI problems. If you are, I would suggest flashing another ROM to see if it fixes.
Update: i solved my first problem by soft re setting it three time that is press and hold power button plus volume up button for almost 30 seconds it restarted 3 times and now everything is fine.. it is capturing signal automatically.... now please tell me about my charging problem.. charging is very slow like 3.4 hours to complete charge... should i use 2A charger??

Sorry, I thought you were having problems with wifi. Glad you got the signal worked out.
As for the battery the power cycles I described (and you seemed to have made) should fixe the problem. Just charge it normally after you do them and by the next charge it should hopefully be faster. It worked for me

ok thanks in case if it is still slow can i use 2A charger?? will it effect battery?
I use a 2A charger. I think the phone takes whatever it needs. Ive always used it on my previous phones with no problem. I usually make sure its from a trusted brand tho

Phone suddenly switched off. Dead, not charging, orange led blinking.

Hello all,
I have a htc desire 820 single sim. I had absolutely no problems with baterry etc.. This phone has only 4 months - i didnt put it into water.
I have unlocked bootloader and rooted my phone 3 weeks ago but it was running with no problems. I didnt install any aggressive software that may brick the phone. I just wanted to get access to all files.
So two days ago in the evening i just installed Skype app and wanted to download a file sent by my friend then in the moment that i was downloading my phone suddenly went off - just like there was no batterry etc (i remember it was more than 30% of batterry). I couldn't turn it on - 0 react. I tried to charge him - the orange led is blinking with 1 sec frequency. I left this phone overnight and still nothing - now its 2nd day that its charging and still nothing. I doubt it was a virus becouse i recieved this file on other phone without any problems.
I tried:
-volume buttons - booting in loader = nothing
-plenty chargers, cables = nothin
-charging via pc usb = nothing
-phone is not detected in pc after i connect it (just orange led blinking)
My question is, what actually happened? What else could i do to try to unbrick my phone?
The day before it got bricked i accidently let it fall down on the ground but frim 40cm distance (i have a silicone cover around) = but i didnt notice anything after falldown.
Thank You for any advices.
I think it's battery problem. I had something similar with One X. You can try leave your phone plugged in to charger (try every micro-usb charger that you have in home) for a night. LED should turn green, if not I recommend send it to htc for battery change or to "professional service" in your city Good luck!
Tighten two volume buttons and the power button when you see a black screen and holding down the volume- and power button that would go to bootloader.Telefon must be connected to kompyuteru
Im trying plenty chargers and cables at the moment - for now= 0 results @vuk1963 i tried your method but 0 react from the phone - just like before.. totally dead- just this god damn blinking orange led..
Edit:
WOW... my phone is alive!! All i did now was:
I tried charger from my galaxy core (same amperage like htc 820 = 1A) but i used original cable from my htc charger. The led was still blinking so i decided to "knock" the back panel (around the place where connector from batterry is), then i pressed vol+ and vol- and power button for around 20-30s, then i pressed vol- and power button for around 30s then i released everything, then i pressed power button for 10sec and my phone turned on!!! im so happy! my phone is still on warranty but i live abroad now so i need to send it to my country to start warranty procedure but no im free of this!
Thank You guys for pushing me to try once more the magical tricks with cables, chargers and buttons
Btw.
My batterry is now 100% = that means it was charging all the time?
i don't know what was that but i am happy that it work now.
Thank You guys!
The phone was overheating and it stopped!
Leaving it for a while, then the combination of buttons did the trick.
Great to hear.
Send it back to htc, mine had the same problem. There is no way they will find out u are unlocked or rooted since it wont start. The problem is the motherboard failed. I got mine back with the motherboard replaced.

Lenovo Zuk Z2 won't Charge. Battery is dead

Hello everyone. My Lenovo Zuk Z2 battery have died and it won't recharge.
When I plug in the charger the bottom of the phone get really hot. at the top of the phone there is a white light that just blinks. the phone does not turn on.
I tried connecting it to my laptop but i only get the message that the usb does not recognize the device.
I would really like to get my data off the phone if it cannot be fixed.
Please help!
Hi there this happened to me to. On its first day so I am sending back the phone.
Any possibility you used quickcharge 2.0 charger? I read this is a problem for the phone and the dedicated chip is broken in the phone what needs to be replaced.
Something similar happened to me too. My phone had switched off after the battery got low and when I tried to charge it, the white LED would blink, the charge symbol would show up at 0%, then the phone would vibrate and the cycle would repeat. I realized the problem was I was using not using the original USB-C charging cable. I had bought an additional usb-c "fast-charging' cable and I was charging using that. Once I switched back to my original cable, all was good.
Might be some hardware failure. Hardware Repairs will probably be necessary
Same problem guys tried using the original cable please helpppp

How you solved this issue? same happening with me as well
Joined just to post this.
I followed the advice from this:
SOLVED: Phone won't accept charge/turn on - Lenovo Phone
FIX YOUR PHONE Remove the cover and then disconnect the battery and hold on power key then charge the phone without battery for 7 sec and then clean the battery plugs not with water dry cloth and then connect your phone this is because of a minor power failure in motherboard and keep the...

different phone, but it worked.
Basically:
disconnect battery
hold power button down for 7 seconds
reconnect battery
charge like normal
I don't know how long this fix works, but hopefully long enough for you to rescue your important stuff.
Good luck.

Phone died over night, won't turn on. Any help?

My LG G7 seems to have died over night. I left it on a Qi pad to charge and after I woke up this morning, it was completely dead. I could not turn it on with the power button ow Vol- and power button. The phone shows no reaction.
I thought that I might have misplaced it on the charger (The phone is quite picky with the right spot) and plugged in my USB charger for about 10 Minutes until i tried to start it up again. No reaction. Tried Vol+ and Power and also Vol- and Power with no luck.
Then I started to investigate and plugged a USB power meter in between phone and charger.
My first try was a cabled USB connection, the power meter shows 5,1V with about 100mA (varying between 90mA and 110mA) and I left it charging for about an hour. Still no luck with any method of turning it on.
Then just to try it out, i placed it on my Qi pad with the power meter attached, which got me 9V with about 200mA, so the Qi hardware apparently is transmitting power. Also left it there for about an hour, still no luck.
I noticed some kind of buzzing sound coming from the phone while charging, if I place my ear directly on the phone. A similar but different noise is emitted by the phone when it is not charging and I hold the power button.
Does anyone here have an idea which might return the phone to life?
As I still have warranty, I consider sending it in. I have backups of the important stuff, but I would really like to avoid sending it in with all the private stuff sill on the internal memory...
What happens when ypu plug it into your pc?
+1 same problem.
Nothing show up when connecting to pc. (no mtp,adb,9008 and etc)
Long press vol- abd power button together
