Lg l70 not booting PLEASE HELP - Android Q&A, Help & Troubleshooting

Hi. I have a lg l70 that I purchased about six months ago. It is rooted and I have installed a custom recovery. Today I wanted to boot my phone up but it just vibrated non stop. I had to pull out the battery to make it stop. When I plug the charger in it also starts vibrating. If I plug in the charger without a battery inserted the phone responds with a battery with a question mark. So the screen works and my system is not deleted I guess? I installed a few apps from the internet just before so it may be a virus. How can i fix it? PLEASE HELP ME I really need it.

[Q] Weird charging problem

My friend is having some problems charging his Atrix. Basically, the phone will not charge or recognize a charger at all except for under certain circumstances.
Some background info: I helped him unlock his bootloader and install 4.5.91 way back when it came out. No problems there, it went well. All was fine until the 4.5.141 OTA update came around. He got the OTA notification and clicked update because he didn't know anything bad would happen. Luckily it didn't brick him like it did a lot of people, but he said it gave him an error message during the install and it would not boot after that, stuck at the Motorola dual core screen. I took a look at it and managed to get into recovery and flash back to 4.5.91. All was fine until it was time to charge the phone. It wouldn't recognize any charger. I tried flashing to tons of different roms, wiping everything, even restored a full nandroid recovery from my working Atrix on it. His phone will charge and will be recognized by a computer immediately after we flash a new rom, and will continue to charge for as long as we leave it plugged in, but if we unplug it then after a short time (like under 30 mins) it will not recognize a charger if we plug it in again. Wiping data alone will not make it start charging again, only actually installing a new rom will. Deleting battery stats does nothing. The closest we have gotten to fixing it was when I made a nandroid on my Atrix and then restored it on his (my backup was from Joker's CM9); after the restore, it would charge for a while, and we unplugged it and waited to see if it would do the same thing as it always did and stop recognizing a charger after a few minutes. About 30 minutes later it stopped recognizing the charger as usual. We played with the USB debugging setting (enable, plug in, see if it recognized the charger, disable, plug in, see if it recognized it, etc) and after messing with that setting a lot it recognized the charger once, but then when we unplugged it the phone wouldn't recognize the charger again. We could not reproduce this again.
To summarize what we have tried and found to work:
-flashing a rom will let the phone charge/let a computer recognize it for as long as we leave it plugged in after the first boot (we have tried every rom under the sun, they all do the same thing)
-restoring from a nandroid backup will have the same effect as flashing a rom
What we have tried that didn't work:
-different cords; have tried them all, both OEM cord and third party, this is not the problem
-wiping all data/factory reset doesn't do anything
-cache wipe doesn't do anything
-wiping battery stats doesn't do anything
I have also tried fastboot flashing back to 4.5.91, CWMing back to 4.5.91, using the unbrick scripts and stock restore scripts people have made, nothing will fix it.
If anyone has any suggestions or can refer me to anywhere with more info on this I would appreciate it, I have searched high and low and can't find anyone with a problem quite like this one. I don't even know if it's a hardware or software problem, if you guys know a way to determine this it would be helpful.
Have you tried a wall charger?
Yeah, both the stock one and a different one I have, neither work.
No one has any advice or ideas on this? Does anyone know if Moto does repairs in this type of situation with a voided warranty because of an unlocked bootloader, or does anyone know who may be able to fix this if I can't get any help from the forums or figure it out on my own?

Samsung Galaxy trend 7560m boot loop

Hi Everybody, excuse me for my english
I am new in this forum, I go to talking about my experience in my case ,I have changed the touch screen it was broken, it this was 2 months ago and it worked very well, however one week ago this frozen screen , touch screen don't response , turn off and remove battery. then turn on and just begin and stop in animacion Galaxy Trend s7560m ,i tried some times and again the same , then i did the next pass
1. - i tried to do hard reset/ factory mode -- I can not get into that mode
2 - Downloading mode -- yes then I installed proper drivers for samsung, installed Odin3 and Firmware for galaxy trend s7560m.
I made the flashing with successful, when end my cell was working well.
This just worked for 5 hours about then the same frozen screen and stuck in boot, I went back to the same old process, and nothing Odin finished with PASS! however cell stuck in boot.
When connect the cell to AC current with the charger this don't charge just turn on and stuck in boot loop one and other , remove the battery and carge a multicharger until fully charged then try remove the battery and multicharger carge a charge until then try again fully loaded firmware and run , after a few days the same again .
I found a way to make it work only when this happens is to put the phone in downloading mode and connect the USB to the computer until a sound is heard connected dipositive wait a minute disconnect the power cell and ready works again without loading firmware , this only works with a limited battery that is only works if you have approximately 70% battery.
I not find way to do to work properly
Does anyone have a similar case? or any ideas will be taken into account
Thank you for taking the time to read this.

LG LS660P soft bricked (Please Help)

H Hi all,
My friend has (I think) soft bricked his LG tribute from sprint. It doesn't charge correctly when plugged into a laptop or the original charger that came with the phone. It just shows the loading battery symbol. However, if you leave it on the charger for about 5-10mins, it will show something up in the top left hand corner of the screen like
[101160] fastboot_init ()
[101260] USB init ept @ 0xffe5000
[101280] udc_start ()
Oh, something that I also forgot to mention is that the phone thinks the battery is at 0% every time I plug it back into the charger, even though I have sufficiently charged it using an external charger. Even when I try to get into recovery mode, the phone won't let me sometimes, because of the supposedly "low" battery percentage. I want to get this phone back up and running, so if ANY of you guys have the same device as me, I need the stock Rom for this device. I have been googling for hours with no luck (the roms that I found weren't in the correct format I needed) A .kdz format is required in order to flash through LG flash tool. Also, take note that this device has NEVER had a custom recovery installed on it, or flashed in any way. If any of you guys have or have found a link to the stock rom file, PLEASE link it in the thread. Thanks!!
Edit: I have found the rom file and have flashed it, and i was able to restore it to factory settings. Consider this thread closed!!!!

Bootloader Problem

So starting off, I'm having problems in terms of the bootloader of this phone. I kinda got bored with the stock so I unlocked Max M2's bootloader to install Evolution X ROM (which where recommended by Max M2 users) and yes I did installed it no problem but after a while when finally charging the phone it started to disconnect and reconnect until it finally wont charge. I tried to charge i through Laptop and yes it worked! but after awhile it started to not charge even on a laptop. So I'm starting to convince myself if it is a software problem or the phone itself. Though that's not the case, it connects to the computer when on fastboot mode so I started to think that it is a software problem. So what I find is that when I unlocked the bootloader it started to charge again and so I waited for 2 hours if the charging problem start to come again and yes it did! so what I did is, I relocked the bootloader and yes! IT STARTED TO CHARGE AGAIN!! (though I'm waiting if the problem starts to come again) so anyone also have this problem? or I did something wrong? I decrypted the device when I was rooting but I don't really know if that's the root of the problem?
Please kindly help me if you know, Thanks in advance!!
It seems like this isnt the case at all, so what I did is I tried to change the USB CONFIGURATION to charging and it started to charge again but the problem is the default is not "Charging Only" rather its MTP so how do I change it back to charging only?
