[Q] Lenovo Vibe Z K910 PC USB connection - Lenovo Vibe Z Questions & Answers

Hi all,
Bought a Vibe Z K910 from China 2 months ago and I'm happy with it. But last week something weird happened and I cannot connect phone to PC with cable. That is not a problem of driver; neither PC nor phone react when I connect the USB cable. But it charges the battery on the other hand. Another significiant weird stuff is that I cannot open USB PC connection (Media device/USB / ....) from settings menu. The page comes and goes in 1/2 seconds each time... BTW, I'm running VIBEUI_v2.0_1433_4_st_k910_baralajbi rom..
My question is that what you guys think if this is a software problem or hardware (broken solder or something) ??? Should I try factory reset or is there any other way to fix it because I dont wanna try to setup all apps.
I appreciate any reply
Thnks

I had this issue with my xperia arc before. You will have to send it back for repairs. Its a faulty board or connection within phone not cable like people say. When i connected my charger the screen would do stuff on its own like open messages and type stuff :S

[Q] USB not detected

Hi, my phone just charges when I connect to any PC, it doesn't detect it on the system and even on the phone. I tried to check and uncheck the usb debugging and the logo came back on the phone (but still nothing in the PC). And now whenever i plug it in the usb debug mode comes and when I try to use mass storage option it allows but PC dosnt respond in a matter of seconds it goes away. My friend had flashed my phone with the stock rom 4.2.1 from XDA itself last year sometime in november and after that it has been great. I believed it was a cable fault so I showed it to a repair shop where the guys checkd with their PC and a new cable and none of their PCs detected it, even the OTG cable they tried wasn't detected on the phone. They say its an error in the Jack which can be repaired in a couple of hours for Rs 250. I have no problem in doing that but I don't know if its a jack error or something inside my phone (some sort of setting) causing it. Please help

Micromax Canvas HD A116- Will Not Connect To PC VIA USB

Ok,so guys,I know this might not be the place to ask such questions,but I m gonna need all the help i can get. READ CAREFULLY:
I have a phone named Micromax Canvas HD A116 . I live in India.So one night,it was raining,and me and my friend were on a scooty,and I was wearing pajamas which had short pockets.I kept my phone in the pocket,and I didn t realize when we were driving the scooty,my phone had fallen down from my pocket onto the slightly wet road.It was drizzling,no heavy showers but still.I went and picked my phone up,and wiped the water off it and we went home.
Now,I plugged it in for charging as usual,but it didn t charge,nor did it show the lightning charging symbol. I tinkered around the settings of my phone and finally got it to charge.
But now I have a new problem: My phone won t connect to my pc via usb cable. When my phone s switched off and I connect it,my pc makes the connecting sound (in Windows 8.1 Pro)
But when I switch my phone on and connect,it doesn t connect and my pc doesn t make any sound or detect it. I have formatted my phone,but still no luck. Any help except getting a new phone? Please?

Is my Sony Xperia 1 Faulty??? Software or Hardware issue??

Issue number 1 - There is no supplied USB cable provided, only a type C to a type C cable for charging. Therefore you are unable to connect it to a computer.
I of course have a spare Type C to USB cable as my other phone (Huawei Mate 20X) came with one. Here is where the problem starts.
When connecting my phone to my computer, I keep getting the following notification:
'' USB device auto-detection stopped. USB device auto-detection has stopped because of a malfunction detected in the USB port. To connect the devices, ensure the port is completely dry or the USB device is not damaged, and tap here.
This is the first problem. Unable to connect to a computer.
Issue number 2:
I am unable to update to the latest software. I've tried wi-fi as per usual and even mobile data and for the past 3 days it says downloading.......
The update is just over 300mb and should not take 3+ days to finish. I've cancelled it and tried again several times, it never starts...
even after stopping the update, clearing cache/data from settings and restarting. Same issue. Xperia system update downloading for many days and not even started.
The phone is brand new, 2 days old, purchased from o2 and has never been in contact with any water yet I am having the above issues.
Any ideas or return it???
Issue 1 - Intended, it's a usb C to USB C cable for use with the stock PD charger. As for not being able to connect it to the PC, try using another cable. If you get the same problem, could be an issue with the phone.
Issue 2: Try updating using Xperia companion (you need to connect your phone to the PC for this)
I have usb 2.0 to usb-c cable from my previous xperia and can connect the phone try to buy such a cable.
Yeah as above, it's your cable thats the issue, and as for the update issue, go to the Sony Xperia 1 support/update page, enter your IMEI number, and if it says, the update isn't needed, then that's the way it is.
I've seen o2 pull an update before, due to their tinkering, it shows up, but you can't download it, as it's problematic.
It'll come round again, soon enough.
The latest so far on o2 is software version 55.0.A.2.205
