It happend this morning i was using my phone normally it had 30 % battery (approx) and i was texting on watsapp and suddenly the screen dims and it was dead it tried every thing but was not able to turn i ton again please help . …………………………………………………………………………………………………………….. it wasn’t dropped got new batteries 1 month before it was 3 yrs old ……………………………………………….
Have you changed batteries,cables,etc. And checked charger port and cable? Sudden death syndrome. Have you had any UID errors or programs deleting? Probably means the Emmc is dead . Happened to my phone. You have to replace the motherboard which is pretty easy. Ebay has note 2 motherboard for $20+. Of course you could try to desolder and replace the chip but its easier to just change the motherboard.
mine did the same thing.answered a call.told them i will call back in a few.go to return the call,and the phone is dead.no lights,no charging,dead.i tried everything.i guess i will buy a motherboard on ebay since i am broke.cant even afford the motherboard but cant make money without a phone in my business.customers call me to do estimates and buy things.its now 3days of still trying to get this piece of crap to work.
I would try disassembling the whole device including flex cables and reassembling, this can fix calibration issues.
