[Q] Nexus 7 is not responding to touch, at all! topic

Hello.

I have recently run into a major issue where my N7 will not respond to touch at all. Checking the bootlog, there is an interesting message:

Now, I know that is a bit dark to read, but here is the text:

Code:

---

QUP: I2C status flags: 0x111163c8, irq: 183
I2C slave addr:0x10 not connected
[elan] elan_ktf3k_ts_recv_data: i2c_master_recv error

---

The status flag hex code changes often, but I think it always starts with 0x1111.

Now, my touchscreen does not work in any location. Running CM12, it refuses to work. Opening TWRP or Multirom, no dice.

This complete lack of touch happened almost out of the blue. Sometimes, my device would develop an issue where it would refuse to acknowledge touches unless they were very firm. However, this is fixed with reboot. Thinking I had this same problem again, I rebooted and noticed my device not responding to touch at all. I then started logging the system, and noticed that ELAN error. I believe this is hardware, but I have no idea how to fix it. When tapping the back of the device, I hear it rattle a bit, like something is loose.

I've kept this device in great shape. It has not been exposed to drops, shock, moisture, or anything of the kind.

[Q] OnePlus One "Device has stopped responding or has been disconnected" topic

After a few weeks since I got my OnePlus, I'm having a strange problem. Whenever I try to copy any sort of data to/from the phone, a few seconds after task has been started I get this error

"Cannot copy file.xxx
The device has either stopped responding or has been disconnected"

Also, the OTG storage devices get unmounted randomly and notification pops up
"USB storage unexpectedly removed"

I reached the concusion (like most of you would) that maybe USB port is malfunctioning.
But here is the twist:

If I connect my phone in MTP mode while in TWRP, the copying/pasting just occurs successfully each time. Even if I mount OTG in TWRP, USB storage works as it should without any issues.

I've already tried:
-changing different ROMs (PA, CM)
-flashing stock kernel, recovery and rom
-using different USB cables
-using different PC
-changing in between MTP and PTP
-copying directly to root, folders and sub-folders

But each time, the copying and OTG storage fails while booted into OS but works normally while using TWRP
