Hi all can someone tell what problem did my phone have yesterday my phone restart alone and stuck on lg boot logo i have mango 7.5 on but i dont now what i need to do i love this phone.help
Pls tell me if is hardware problem or software or my firmware is dead
I dont whant to spend money with service
Could be either, what i would do is pull the battery out first and leave it out for 10 min. Turn it on and see what it does. If it still does not work try a hard reset. Turn the phone off, hold volume up and down and the power button at the same time for like 5 seconds and then release and follow the prompts. If that does not work i would say its hardware.
Pull the battery, put it back on and plug it to the pc while turned off. Try this, it may help. Otherwise you can try and see if Zune detects the phone while looping, if it does you can try to roll back to the previous firmware.

If you've tried all the other suggestions and have no results, you may be forced into the "nuclear option". Download the firmware from here: http://forum.xda-developers.com/showthread.php?t=935605 and put into emergency download (slide keyboard open, hold the space bar while pressing the power button). You'll also need to download the LG flashing tool. Use this tutorial as a guide http://forum.xda-developers.com/showthread.php?t=935605
Hope everything works out for you.

Hi guys,
I was wondering is a phone repairable if it will not power on after flashing KDZ? I mean like it has no power, won't turn on, won't be recognize by computer? Is there any trick of the trades? Thanks.
Yes, JTAG, changing mainboard or go to service centre.
Many users asked that, why do you don't search a bit? If you don't find it, you can ask.
Hi everyone,
I'm currently trying to fix an HTC Sensation for a friend. The original problem was a faulty charge port. I tried replacing the port via heat swap but ended up burning the board. So, I changed the whole motherboard. After assembling everything back, I connect a USB charger and eventually the a green LED light shows. I then hold down the power button and let go, I only a get brief vibration and that's it - no display. I connect to my desktop PC and under Device Manager it detects it as a general HTC device.
I asked my friend if the LCD had any issues before, she said it was fine. I also checked the connections between the board and LCD, reseated many times.
Could anyone give me any other possible issues before I consider swapping the LCD assembly?
Thanks.

did you try to enter into bootloader?
remove battery reinsert it
press + hold power button and volume down until it gets you to the bootloader screen
after that choose fastboot->reboot
Hey guys, So i was using my Samsung Galkaxy S6 one day when the screen went dead. Now it will not turn on or charge, I have tried using 3 different chargers and tried to use all of the button combinations to reset it and boot it into all the different modes. I have even tried to just let it charge for half a day but nothing. Does anyone know whats wrong with it, whether i can save it or if i'll have to get a replacement? I have emailed Samsung but they still haven't replied yet. It is running stock android not rooted and when i plug the charger in the device gets warm but will not turn on or show any signs of life
Cheers everyone x

Like i said in my post I have tried every button combination including Volume down + Power button. Thanks for the thought though
When you plug it into the computer does the computer see it ?
If yes, then your screen may need replacing. If No there maybe a problem on your motherboard.

The computer does not recognise it either. What you said about the motherboard must be the problem then. Do you have any idea how the motherboard could have been damaged and whether it was a hardware failure or my fault?
Easy on the MB replacement! They're the most expensive thing on the phone. Try the USB port/daughter board 1st. About $6 on eBay. After that if no joy- have to swap in a power amplifier. Here's a link how to

Not fun but might be necessary. I'll bet it's not your MB.
Hi All,
I have LG G Flex 2 H959 which is not rooted.
One day the phone just switched off after I was on Chrome for less than a minute, the battery was at 70%+ when that happened.I was unable to turn it on immediately so I went to charge it however I noted that the red charging indicator light was not on and stopped charging it.
I tried switching it on again the next day and the screened turned on for the first time with the low battery screen. I proceeded to charging the phone which managed to charge with the indicator lights for less than 5 mins before it stopped charging. I tried switching it on several times with the volume up/down held and some of the tries allowed me to enter the phone until the optimising of apps started (with a lot of difficulty) before crashing again.
More recently, even the low battery screen failed to switch on too. The screen did manage to come back on after I disassembled the back and moved the cables and battery about a little to only die again after charging. I had tried to connect the phone to the PC with the volume up button pressed, but the phone was unable to switch or be detected.
Anyone with experience in this issue able to identify the cause of this? I understand it could be an issue with the battery or motherboard. If it is a battery issue I would buy a replacement to do it myself. However if anyone pins it to a motherboard issue, I would just give up on the phone as they are costly and not worth the purchase. All you inputs will be helpful, thank you.
dissemble the back again and check battery voltage and also external charge (Carefully) if possible..
Also there maybe fault with the charging / usb port..
Rust ? and hence short-circuiting??
Get yourself a new battery!

Thanks for the replies, ok I will check the voltage and search how to check the external charge before purchasing a battery. I will also check the usb charging board and see if I can purchase it online, haven't been able to find a place which sells one piece.
I did not observe any rust on the circuitry, that should not be the issue.
