Am having this LG Optimus G Pro F240L for about a year. I have rooted it 2 months ago via CWM, but am on stock ROM. Two months ago, it started behaving badly, as it Front Soft Keys stopped working, and it pull me out of every app, seems like back key is being pressed without actually touching it (though the keys were not working actually). I have installed Ultimate Dynamic Navbar Pro app to get the Search, Back, Home, Menu,and 3 Dot keys on display, which helped me to keep this phone working easily. Until last night, everything was working smoothly, it had no other problem than those soft keys not working.
Last night, I didn't put it on charging, as I used to do regularly. It was around 40% battery when I put phone on my desk before sleeping. Today when I tried to unlock it, pressing unlock key, it showed nothing. I pressed it long thinking it might be off, but nothing happened, so I put it on charging, thinking the battery is drained completely. but even after an hour, it doesn't seems to be charging as bo red light was there on home button. I pulled out battery, wait for around 5 mins and put battery there, but no luck. I then grabbed my multimeter to check battery voltages, it shows 3.97V. Now when I put the multi-meter probes on VCC(Red probe) and GND(Black probe) pins on phone, it shows 0.434V without battery and 0.560V with battery inserted.
I charged my battery a little bit potential difference with an universal battery charger, upto 4.12V, but still the phone is not booting. I also checked for the power button failure, as there might be a chance of loose contact of pins underside the board(read somewhere), but it was fine.
Am not able to figure out where is the fault. If uUSB charging jack is crappy, then after charging the battery from other source must have worked, also if charging jack is fine, then the potential difference across VCC and GND must be around 4+Volts which is merely around a half volt.
I tried to get into CWM but no luck, I tried to get into download mode(pressing both volume keys and inserting uUSB just after it), but still no luck. I don't know how it got bricked, as I haven't made any changes recently, I was using it at a daily go. God knows what happened to it. It is out of warranty, again am out of luck.
please help me....
I have only LGFlastool_1.5.10.1120, LGUnitedMobileDriver_S4981MAN37AP22_ML_WHQL_Ver_3.8.1, WindowsLGFirmwareExtract-1.2.1.0-Release, a Windows 7 and a Windows 8 pc and a linux Ubuntu distro, a fast broadband internet, Android SDK installed with adb drivers, and a knowledge of how to root and flash ROMs(had several android phones over past years, rooted and installed several ROMs like cyanogenmod on Samsung Galaxy Wave II, Samsung Galaxy S I9000, Sony Ericsson Xperia Arc, Sony Xperia J, Samsung Galaxy Ace S5830, and a several ROMSs like PACMAN, SlimROM, SpeedDroid, MarvellousSense on HTC Wildfire S A150E) and flashing CWM recoveries aka recovery.img and boot.img from cmd and Flashtools.
I need your help, as all this knowledge is useless without your help, please help me, am stuck here so badly. I'm ready to take chances, please I beg you...

Maybe hardware issue.
I see that you have already posted on your device specific help forum (http://forum.xda-developers.com/optimus-g-pro/help/lg-optimus-g-pro-f240l-bricked-boot-t2862582).
That's the better place to get help IMO.
Hope that you get some advices there.

Hi guys
I've had the Sensation for about 3months now, and suddently yesterday it stopped working. It wont charge, no LED's and wont start at all. There have not been any waterdamage, drops or rough use.
I've read a lot concerning similar problems on this forum, but none of the solutions has worked for me.
What I can tell is that I have tried after searching the forums:
- SDK, ADB and try to reboot the device via USB-connection (device not found)
- Win7 (32bit) can't recognise the phone (asking for drivers which are not found in HTC Sync, QHSUSB_DLOAD)
- Trying to enter recovery mode (Volume Down + Power up)
- Charge the battery overnight
- Charge the battery with a plastic-piece covering the two middle pins on the battery (As suggested in a thread)
- Battery out for 1min and then put it back in and start up
Neither of these worked, so are there any other good ideas? Or is it bricked?
Hi guys,
i have exactly the same problem, already have tried all of these solutions, nothing have worked for me... Please help.
PS:sometimes my screen lights up <black totally, but lights up>... when plugged into usb cable or charger... but not now anymore...
I have bought this phone in china, there is S/N but i guess that here in UK i cannot do anything about it since HTC's warranty is not global...

Also keep note of which recovery you are working off of. There have been charging issues with certain recoveries.
Yeah, I read several threads and posts about recovery-issues... Unfortuantly I cant check what version I got myself, as it wont start up at all :/

I would suggest to go to a store that sell's the Sensation and ask if you can test one of their batteries out to see if your phone has either a battery issue or something else. If you are stateside, of course try a tmobile store, but without knowing where you are located, this is a hypothetical at this point.
I know I had an issue with my Nexus1 not booting up from a kernel I had flashed. But I noticed my charging led was flashing three times and then stop. I researched this here on xda and found that it just needed to be put into recovery again somehow. I ended up just plugging the phone into the wall and remove the battery. Try to power it on there and then reinsert the battery and try the power + volume down button. That time it booted for me. But again, this was for my Nexus1 not with this phone.
same happened to me, sent to HTC and had main board replaced, lcd, flex cable etc. the driver the phone looks for is the equip HTC use to jtag... I am not sure if this is a hardware failure or boot corruption...but even though it was s-off via alpha rev it was that damaged they didnt complain... i say hardware failure. the thing is even when i have s-off i didnt change the rom. I have a riff box on order so if this happens again we can surely see if this failure is software or hardware..
Yeah, do what kpjimmy said; go to a store where Sensation's are sold and ask if you could use a battery to test it out to see if it's bricked. It it's not, you'll need a new battery (try getting one for free from HTC, citing warranty. I did it with my battery cover). If it doesn't work, you're mostly likely bricked, unfortunately. Refer to anarchy's post for more info on that side of things

Havn't had the time to really do any custom ROM or the like, so the phone was all original from the factory...
Hello everybody. You're my last hope!
Here's my situation: I bought a second hand Note a year back, and it's suddenly done a hard brick on me. So hard my computer can't even see it when I use the USB data cable.
I'd rooted it with CWM, flashed a custom JB ROM, and had been using Link2SD to shift some non-essential apps to a secondary partition and free up some system space. Although all the above came with their hiccups, I'd been using the phone without a hitch for about a week when "it" happened.
Today I pick it up and it has the "Galaxy Note N7000" welcome screen, which disappears when I hold down the power button. After that, nothing. Nothing from the power button, nothing from the power button+menu button+volume up. Nothing when I replace the battery with my fully charged spare. Nothing when I plug it in to charge, nothing when I connect it to the PC. No warning, nothing. Out of the blue, just like that.
After a bit of online rummaging I think I need a JTAG fix, something like "Samsung Galaxy Note - JTAG Brick Repair Service (Debricking/Unbrick/Brick FIX)" by MobileTechVideos on Youtube (I'd paste a link, but this site). Problem is, I'm all the way out here in Turkey. What would you suggest?
Thank you in advance.
PS: I'm struck by how all this makes you appreciate the simpler things in life. Like your father-in-law's little old beat-up Nokia that never skipped a beat all these years and is now saving your life. Is it really so hard to make a phone that is guaranteed to boot no matter what?
Hello, I bought a Z2 back in November, but it completely stopped working after 6 weeks. No customs ROMs, no root access, nothing. It started lagging, so I was going to restart and it just wouldn't turn on (I turned it off at 32% battery). I plugged it in, and no charging light o anything. I was away from my house for the weekend, so when I got back home I tried seeing if I could fix the issue. Luckily, I still had my old LG Optimus G Pro (that i'm still using). I bought the phone new (sealed in factory packaging) from eBay (never buy from seller "never-msrp") and their return policy is 28 days. They woudn't take it back, and after calling whoever I could to get my money back ($439.99) the bank finally gave it back (they might not let me keep it, I had to send a letter explaining what happened. Still waiting to hear back). So, 2 months after it stopped working, I'm stuck with a broken Z2. To explain what it does: at first, nothing. No lights, vibrations, nothing. Now, if I plug it in, the red light comes on, but if i unplug, it still does nothing. When plugged in, the phone will have a red light, but if I push the power button, it starts to blink very slowly. Like on for a few seconds, off for a few seconds. Different combinations of power and volume keys yield the same result. Pushing the red reset button when plugged in makes the phone vibrate 3 times, and nothing else. not a thing. Pushing it while unplugged does nothing. The computer does not recognize the phone, and the PC Companion won't install correctly (I get an error saying the program did not install properly). So at this point, I don't care what I do with it, I just want to make it run something. Android, Windows, I don't care what. Is there any way I can get this phone to boot up into any OS or is my poor phone done for good?
PS: I called Sony and asked if I could get a replacement, but when I provided my IMEI, they said my phone was from Hong Kong, was never meant to be sold (whatever that means), and has no warranty. So that's no use.

Hey everyone 2 weeks ago I was using my lg g2 verizon model running android 5.0.1 lollipop and it felt from my bedside. Note this is not her first time the phone had fallen. I have a tpu case on it and it usually fears very well against occasional drops. That fateful night however the phone fell and when i picked it up it went blank and was switched off. I tried to power it on by pressing the power button but the phone just vibrated continuously on a second by second basis ( literally counting mississippis). I then tried to plug the phone into my wall outlet to force a boot but it just vibrated too.
Later that week i opened it up removed and reattached the battery cable and IT CAME ON!! Two short days after i rebooted the device for a new app but then it didnt power on. The same problem occured. I tried my fix again and after a couple of tries it finally worked. A week later and forgetting my phone problems i restarted ny phone again only to find out that the problem had returned. After trying my quick fix over and over again, nothing seemed to work so i decided to try troubleshooting the device myself. My results have left me baffled.
Ok so before you guys start shouting out solutions, heres what did and found ;
1) Tried a new battery and the phone still vibrated.
2) Unplugged the battery from the motherboard and plugged in my charger and the phone still vibrated. Lead me to believe that its not a battery problem.
3) Removed all un-neccessary components from the phone ( camera, screen, mic, antennas, etc...) the phone still vibrated.
4) Removed the power button module from the phone and it still vibrated when the charger was plugged in.
Note: I disconnected the vibrator behind then motherboard and held the phone to my ear while I plugged it in to my wall outlet. I could hear a faint clicking sound in a cycle.
Im completely lost sorry for the long thread but if anyone can offer some advice please help me i have no money to buy a new phone atm #life
Thank you in advance xD

Hi and thank you for using XDA Assist
Unfortunally for your phone this is indeed an hardware problem and i doubt it may be a software one...
If you didn't "worked" on the device from the software side i think the better way is to take it to an assistance shop or something like that in order to fix your vibration problem.
But for futher assistance i suggest you to ask overe here: Android Q&A, Help & Troubleshooting
Or here:
G2 Q&A, Help & Troubleshooting
Good luck!
Hello xda community ( first post )
So i own a sony Xperia neo V and i have a very weird problem. So I left it charge overnight and the morning i tried to turn it on but it wouldnt turn on. I tried a lot of things until 1 day later after removing sim and sd and pressing vol up+power it turned on. I backed up everything and tried to turn it off and again on but again it wouldnt!
O dissasemplied it and cleaned everything in case there is a short circuit. i unplugged and repluged everything i could inside it.
I left the battery out for 1 month.
I tried the battery on my xperia tipo and it was working fine.
I made a hard reset.
I made a topic on sony site they didnt help at all, they just said the obvious things.
Now I am trying this forum, my last hopes to make it work again. Right now i turned it on and it works fine! The power button works always in both press and long press. The screen and touch screen works fine. Everything works properly. No sim or SD inserted.
Help
Ask me whatever you want i will try to answer everything. Please dont tell things like remove battery and stuff i already tried these.
The weird part is that everything works fine! but still it wont turn on 99% of times. i tried to keep track of the things i did to find a pattern of things but it turns on totaly randomly. There is no procedure that has more success than just pressing the power button and hoping to turn on.
Additional info: It has suffered water damage some times in the past and many falls from about 1 meter. It always worked after leaving it on the sun for a day or two without the battery and turning it on. I found no rust or corrosion signs when i dissasemplied.
Thanks!
EDIT: I found out that if i change the pressure i apply on the battery connectors the device has a higher chance to turn on!
