Hi There,
Wondering if someone could help. I had my Mk808b for a while , is rooted and worked very well , until yesterday.
Now doesn t seems to switch on , it was power up with a usb travel charger ( the one I received when I bought it see attachment)
I tried another television that I use as a monitor for my pc and when I connect the usb cable to the pc to power it , it does work , but if I connect it to other power supplies it doesn t .
I truly don t understand why

good day to everyone. firstly, i would like to thank you for having the time to read my post.
well basically heres my inquiry, my unit is the alcatel tab t10. i never had any problems with it until recently, my device's usb port suddenly stops working.
tried unchecking the usb debug mode, tried checking it but to no avail, the usb still does not work. it doesnt seem to connect to my laptop. tried changing the cable.
i also tried connecting my device to my brothers laptop.
correct me if im wrong, but when the usb fails to connect to any laptop, their should be a notification in the laptop that the device is not recognized. but in my condition, no notification shows up. its like my device does not really connect at all.
oh and if it helps, i bought an otg cable before it started malfunctioning. but the only thing i had conneceted to my device is a wired mouse and a wired generic gamepad, which both seems to be working perfectly fine.
also, if i connect my device to a wired mouse, it would work perfecly fine. i could also connect to a usb flash drive, that is via the otg cable.
so whats weird is that the usb cable does not work, but the otg cable works fine.
if you have any question or any suggestion , i would truly appreciate it.
Hmm.....well the good thing is the port itself isn't "dead" as you can still utilize it for OTG. My only suggestion is make a backup of all your apps and data and try a factory reset.

thank you for the suggestion guitarman2010. unfortunately my usb port isnt still working. i also reflashed my device's current firware. but still wasnt the solution i was looking for. i was just wondering if there is a directory under the root folder that holds the devices usb driver? would it be possible that the device's driver itself got deleted? i wam still at awe that the otg cable still works like a charm.
and another thing, is the male usb pin the same with the flash drive's pin? cause if i connect the usb cable to the otg cable it wont work, but the flash drive works normally.
sorry for the amount of question im posting
thank you very much for the suggestion. especially when u told me that the port itself wsnt dead. i can now breathe easier..
and future suggestion and advice would be appreciated.

Hello,
Today I have received new korean version of LG Optimus G and I immediately notice one problem. When I connect phone to PC via USB touchscreen stop to respond. The phone is not frozen, I can see that it's charging, the clock is working, hard buttons like VOL+ and VOL- and power button also works but touchscreen is unresponsive. This only happens when connected on PC or laptop via USB. Everything works when charging with wall charger. I've tried different cables, also on my PC and laptot, and always the same. Touchscreen doesn't work while connected to PC. When I unplug cable everything works well. I would like to emphasize that this is my third korean Optimus G. Never got this kind of problems with previous two.
Any solution or suggestion?
Hello everyone,
I am having a problem, my android (Overmax Vertis 4510 EXPI) can't connect to computer. I think the problem is fast charging (AC), but this phone doesnt have off button for fast charging, so I downloaded a program that disables fast charging. It requires root, and there is almost none root for this phone, only through computer, and how you know i can't connect my phone to computer...
Any help would be appreciated.
Sry for bad English.
Hello there!
Guys sorry if already has something treated about this around here ( I did not found), The problem: My Xoom 2 are starting normally but the touch screen not "answer" the commands..
Its did not down or was kick out or something like this... ( at least were what my wife said ).. The workaround:
I can't buy the new screen for now, so I put one usb hub (It is energized) , on this I put mouse and keyboard, and still are using micro hdmi adapter for the monitor, on really its on micro hdmi adapter + dvi on the other side ( because my monitor dont have hdmi port , just vga or dvi )..
Although of all this , are working, but its froze the screen after some minutes( 3 / 5 minute +/-).. I already left some option "on" in settings( not turn off , usb depuration..).
Please, what would can I do to make its works less stoped? Can I turn off the screen on the Xoom and let just working on the Monitor?
Its general here so i think i can ask this kind of things so ,I m an IT guy that has run out of ideas. I would like to ask you some questions about a (probably hardware realted) problem that i have. All started suddenly , from one day to another all usb ports, camera and bluetooth stoped working. I dont really care about the bluetooth and the camera, the only thing i care about are the usb ports. I 've checked them with a multimeter (only the pins that provide power) and the strange thing is that they do provide power. If i connect something like a usb flash drive , the led flashes (stays on , doesnt flickers) but nothing happens. I am sure that's not a drivers problem because the laptop doesnt even recognize them in UEFI nor CSM. My UEFI does not have an option to completely disable usb ports, only to change from usb 2 to 3 (no change at all). I m sure it's now a power problem, i ve reseted the bios even by the motherboard jumper.So the question is , what it may be? is it a motherboard malfuction ? Can it be fixed? Also , is there any possibility that for example the camera is faulty , or the camera cable , and shortcutting something? (i mean if i disconnect the camera and the bluetooth, is there any possibility that it will be fixed? ) thanks in advance.
p.s. also on the motherboard there isnt anything strange like a blown up resistor or something.
