I have a problem with my LeMax 2. I was using google camera for some picture taking, and all of a sudden phone shuts down. I connected it to the charger, thinking that the battery is dead, but all I can see is backlight, without anything on the screen.
then I connected it to a computer, and there was a popup that said: "the last device you connected to this computer malfunctioned". it seems that USB cable is burnt out. I changed the USB cable, but the same error occurs.
The strange part is that i get notifications, I can locate the phone via Find my device, but i can't see anything on the screen, only i can see a backlight. PC does not recognize it, i tried Linux, win10, win7, USB OTG. i ordered a new Dock Connector Charging Port Flex Cable https://www.aliexpress.com/item/Original-New-Dock-Connector-Charging-Port-Flex-Cable-For-Letv-leEco-Le-Max2-Max-2-X820/32828762033.html?spm=a2g0s.9042311.0.0.116b4c4ds9GGuN, and changed it, but the problem persists.
i can only see backlight, the phone can be located, the notifications can be heard, but USB is only good for charging, even after replacing it.
Does anybody have some idea how to revive it?
Heyyo, hmm does tapping the power button allow the backlight to at least work? Please rest that in a dark room to see if you can notice the backlight.
If not? It could be a hardware issue... You could try heating the device with a heat gun and then using a suction cup or screen seperation tool and then check the connection of the screen to the device and ensure it is properly connected.
There could be other recommendations if someone else also has an idea
Yes, the backlight works. I opened phone, changed USB port and checked the screen connection. Firstly I thought that USB is fried due to some weird power surge when connecting the charger, but after changing the USB, it is the same.
The next thing that came to my mind is that USB connection on motherboard is fried. As I said, the phone charges up, but when connected to pc, it shows that device has malfunctioned. The screen has backlight, as far I can say it registers a touch, device finder can locate it, sound works...

I noticed this issue, where the Photon powers on by itself when i plug it into the computer via usb.
When the phone is off and plugged to the wall charger I get the battery charging image. But When the phone is off and plugged into the computer via usb, it powers on. Also With the usb plugged in and in charge only mode, when i perform a shutdown on the phone, it restarts right after completing shutdown.
I know this might now be a serious issue, and no one have probably come across it but same thing happened when it was connected to the PS3, i powered it off while it was on and connected to ps3 via usb and it powered back on. This could be some weird usb sending out signals trying to mount the sd card and in return it forces the phone to turn on, can someone please verify this on their phone, my brother has a photon i am gonna try this on his later tonight, just need to know it is on mine,
Well i confirmed with another Photon, it is the same issue, whenever it is plugged into a USB it turns on by itself, dont know if this happens with other phones, but it is weird

Same thing here and it is so annoying when I am just trying to charge it and it keeps booting back up.
does anyone know of a solution, i ll try playing around with it, may be something with usb debugging, highly doubt it though
Same here. I think it must be designed this way for some reason.
Does it turn on if the USB is set to 'Charge Only' mode? I think it turns on automatically by design in Phone Portal or Sync modes but it probably shouldn't in Charge Only mode.
Hi,
i have a NT , when i plug in the cable to my pc it shows he usual USB mode.
is there anyway to have it in usb mode but be able to use the tablet at the same time ? in other words get rid of the damn pop up and let me use it while its in usb and charging mode ?
thanks
you could try disabling automount... maybe the USB window is triggered when the SD is mounted for computer use.
That is absolutely correct. If you don't know where to find automount, it is accessible through the nt hidden settings app.
ive also been seeing a weird issue , ive done that in the past , but when my tablet is connected to power / computer usb cable to any power source my touch screen is funky , when im on the lock screen i can do stuff , i can pull the bar over to almost get it to unlock but when and if it does its funky , i just kicked it out off of auto mount and i have what i want except touch screen is not actually working , if i unplug it from the cable the screen works ,
any ideas ?
You could also try "ejecting" the device. That might put it in charge state and allow you to continue using the device.

I haven't noticed the "funky" screen on my NT, but have experienced it on smartphones in the past and it was associated with a noisy charger. Try using different chargers and see if the problem gets better or worse.
ah yes you have a valid point i have two NT's one for me and one for my gf hers blew a charger and we had to have B&N replace the usb port receptacle already , had it less than three weeks. I will try it with her usb cable and see what i get as they changed the whole assembly and if it does not occur with her new cable i will get them to exchange it before the 1st ..
Hi!
So basically I can charge the tablet with no issue but when I connect it to my pc (or the one at work) it suddenly is no longer being detected (no USB plug in sound).
At home I was able to make it work but it would seem that moving the cable a bit will make it go off so somehow the cable must be bad I think even though physically outside it looks great.
Could that be it?

its very plausible that you could have a bad usb wire. if you wiggle it and get a connection very likely turns to 100% sure. There are different wires for charging and data within the cable. no connection when you plug it via dock either? (just want to rule out on board connector)
I will have to test on the dock but when it connected yesterday, I tried moving the plug around the table area to see if it was there and it never disconnected yet moving from the USB side connected to the PC made it disconnect so it makes it sound like a bad cable for sure...and hopefully
I have an i777 (AT&T). I would like to root it. When you connect the micro USB cable, the phone starts to act strangely. First, you cannot charge the phone through the cable (I have to use an external charger and keep switching batteries). When you connect the cable, the phone does the following: every six seconds the black and white battery charging icon appears in the middle of the screen (the one that you see when the phone is off), and stays there for a split second. Then the screen is black until the battery icon appears again. The phone cannot be used while the cable is connected.
There are ways to send files to the phone (Kies Air) that let you work around the cable issue. But does anyone know how to fix this USB cable problem?
Thanks.
DO not charge your phone with it
Seems like your USB port is damaged and you can damage the internal parts by giving a fluctuating power supply
Hi. I have the same problem. Could you fix it? Charging and data transfer can be solved (external battery charger - airdroid) but I do not know how to root it. Is there any wireless way to root the device? Thanks
Hi,
I have a problem with the battery charging.
The USB port doesn't seem to work at all in all situations except when i switch off and connect the charger or to the pc.
In that case the green light will come on for a few minutes or seconds and the phone will start automatically but after that the the port seems to loose functionality again.
It doesn't seem to be recognized as a mass storage device and neither can i get it to be recognized by flashtool.
Anybody has any idea what might be the problem?
Same prob
I have the same problem and its only getting worse,
for me it wont be recognized either but since a day only the wall socket will get the green light to burn.
Im guessing sending it in is the only option for us.. :crying:
