[Samsung Galaxy Nexus] DrKaputnik:
Hello!

First things first: i already googled and search-functioned about 8 hours for solutions, tried them all and still got no luck so basically you girls and guys are my last hope. i hope my english isnt as rusty as i think it is. if i make any mistakes of any kind, please bear with them.

Used Hardware: Galaxy Nexus, the original Samsung OTG cable and the original Samsung charger

Software: Rooted, Bootloader-unlocked, stock-Android 4.0.4, 4.1.1 and 4.1.2

What is my problem?

as soon as i plug in the original charger it charges (duh!)

however, the moment i unplug it, the phone keeps thinking it is being charged. forever!

plugging in a original samsung USB cable without connecting it to something doesnt help, it still thinks of being charged.

but plugging in the original OTG cable stops the phone from thinking of being charged! (i dislike the thought of running around with a OTG dangling around the phone so that isnt a solution to me :p )

what happened before that incident?

bought on 15th December 2011

last software update 4.1.1 to 4.1.2 on 16.10.2012

worked perfectly until Yesterday

Recently i played around with the OTG cable and tried the following hardware to see wich works with my setup:

external HDD - NTFS formattet

PS3 Sixaxis controller

Corsair Flash Voyager USB3.0 Stick

AKAI MPK mini USB MIDI controller

Newest apps installed:

Sixaxis Compatibility Checker (18.10.2012 installed, used for half an hour and deinstalled)

Wolfram Alpha (17.10.2012 installed)

MyBoy (an GBA emulator - 12.9.2012 installed)

-latest ROM for that emulator downloaded on 13.9.2012

what did i try to fix the problem (in exact order)?

rebooting

changing the battery from 2000mAh (its an original, bought about half a year ago) to stock 1750mAh

removing the battery for 10 minutes

draining the battery to absolute zero and fully recharge it

carefully cleaning the microUSB port (with battery remover of course)

super carefully bending up the thounge-like part inside the microUSB port so that it doesnt get in contact with any surrounding metal parts (battery removed of course. when i say super carefully, i mean super duper carefully! i know how fragile those parts are!)

trying to hard reset the phone (that was a failure i just got from fastboot mode to a droid with a red triangle and an exclamation mark on its open stomach)

factory resetting the 4.1.2 via factory reset option (backup with Titanium Backup was made correctly but i forgot to copy it from droid to PC :silly: )

wiping the cache via fastboot

quick reflashing the 4.1.2 via fastboot

quick downgrading back from 4.1.2 to 4.1.1

quick downgrading back from 4.1.1 to 4.0.4

quick upgrading to 4.1.1 (it still is in that state)

complete reflashing the 4.1.1

- with reflashing bootloader

- with reflashing radio

- with reflashing recovery partition

now i am out of ideas :eek:

i think the USB port is seriously damaged. but since i am not so good with soldering and electronics i fear that i am not able to exchange that.

any more suggestions or ideas what might have been the cause?

next few days i will take it to the service center wich i really dislike to do because here where i live that means they keep it for about 6-9 weeks to fix it and i will not get a replacement in the meantime. anyhow my hopes are low that they might fix it i rather believe they replace it for a new one wich i also would dislike. Good thing i made a insurance for that device so in worst case i dont have to pay a single buck...

greetings everyone
