No pc connection (only charge)

[forcedv]

Hi guys

Have a Galaxy S7 (uk O2 unlocked) that was working great until the latest ota update about a month ago (Android 7).
Since then it will not connect to PC or OTG adaptor.
The only thing it will do via USB is charge.

I've enabled developer options and chose MTP connection. No luck.
I've done the *#0808# and set MPT and reboot. No luck
I've look closely at the USB charging pins and they look clean and not damaged.
I've changed to USB cable. No luck
I've tried a different USB port on PC and different OTG adaptor. No luck
I've done a full factory reset. No luck

The thing is, I am willing to try installing previous versions of Android software but without a PC connection I don't know how I'm going to proceed.

The phone is not rooted (and I do not want to root it).

How can I fix this problem?

Generally a problem with the USB port/cable as the charging and data pins are separate so one can fail while the other works

Quite a few people have had to replace the phone charging port, if it wont' connect in Download Mode, then the firmware update is not the cause, download mode has nothing to do with firmware

Ah, so you suggest putting the phone into download mode ( vol down + home + power) and then connect to a pc?
This should eliminate the firmware been at fault?
Correct?

Yep, and is also the way to flash a new stock ROM with ODIN

Just tried this .... nothing

Just to make sure, I put a friend's S7 in download mode and it connects to the pc just fine.

What's the cheapest way to repair the micro usb port in the UK?

Cheapest would probably be eBay and doing it yourself, but the unit is sealed and needs a heatgun to remove the back

Plenty of tutorials on YT though if you want to give it a shot, next cheapest would be one of those dodge phone repair shops but I wouldn't be trusting them my with S7, or if it's still under warranty, Samsung

I've had a look at my paperwork and it was part of the O2 refresh deal that came with 12 months warranty.
I've cancelled my contact with them but paid for the S7 in full and it 11 months in.
Even though I'm no longer with O2, they should be legally required to fix it, right?

I'm also with o2 for mine, when I had problems with the camera I contacted Samsung UK via twitter who offered me a courier to collect free of charge and have it repaired under warranty

Try both, don't suppose it matters really but might have more luck with Samsung as you've paid off o2 already
