Won't Connect to Pc?! - Nexus 7 (2013) Q&A

I recently reset my device and did a wipe with Twrp so I could install Los with it, now currently the device has nothing on it but cannot connect to my pc for whatever reason, I tried installing drivers through Restock, and it even charges with the device powered off I have also tried other cables is there something I'm missing here? I don't know how to move forward and it used to work perfectly before the reset.

This seems to be a frequent problem with our almost eight year old N7s. There is a ribbon cable connector on the motherboard, the top board inside the tablet, which is prone to lose connectivity over time. There are inserts on the inside of the rear cover which apply pressure against two ribbon connectors on the motherboard. The ribbon cable connecting the lower, USB board to the motherboard carries charging current for the battery, USB data to and from the external USB connector, touch input from the screen and for the LTE N7, SIM card data.
Remove the rear cover, connect your N7 to your PC and see if connectivity is restored when you press on the left ribbon cable connector on the motherboard as viewed from the rear. If so, you can try adding some cardboard between this connector and the back cover to increase the pressure applied to the connector once the rear cover is reinstalled.
Good luck.

Tiny USB Cable

So I had installed a 2012 Nexus 7 in my car dash. That went relatively easy since you could just move the ribbon cable for the charge port and plug almost any cable into it. I have it apart and decided to upgrade to the 2013 version. The problem is the screen is attached to the same board the Micro usb port is soldered to and I have almost no room on the side of the tablet. It being a Hair taller is killing me. Does anyone know where I can get a very low profile micro usb cable? Something similar to what is attached to this charger. Need it to have data as well. Or if anyone has any ideas on what could be done I'd like to hear.

I want to use 90 ° micro usb cable, that would not fit?
An Idea
The board with the micro USB can easily be removed with a small screwdriver so it would just hang behind the nexus inside the car. That's no good if you plan on using the nexus like a regular tablet.

[Q] Cables always come loose?

I have had my Nexus 7 2013 pretty much since launch date and I have always had a problem with the micro usb cables coming loose (I have tried various ones). This has never really been a major issue until recently I bought a OTG Y cable to connect it, and then to connect a Wireless adapater to it for using Kali Tools on my tablet.
The problem is, the slightest touch to the cable, and I mean you only have to look at the cable and it comes loose effectively disconnecting and interrupting the power from the OTG and wireless adapter.
Is this a known problem and is there a fix?
The cables just never seem to go far enough in and wobble side to side far too easily, so although it was never a major problem for me before I am finding it extremely annoying and frustrating right now!
Thanks
Take the back cover off, use a pair of needle-nose pliers to GENTLY squeeze the connector back together, replace back.

Problems with USB connection

I had been somewhat unlucky and while charging my beloved FLO something went puf (literally). After that I don't have any USB connectivity. Charging my N7 works (very slowly), but no USB OTG or USB ADB. OK Fine and dandy if I wouldn't be total idiot and wipe system while trying to install new ROM before transferring ROM image to internal storage.
Now I have FLO paper clip able to go to TWRP but can't install nothing. As far I understand there's no way to enable wifi in TWRP.
Any ideas what would needed to be replaced to make my FLO work again so I can put some ROM on it and make it work again.
I'm not sure if USB daughter board would suffice and solve my problem. Any suggestions?

Either the USB port developed "dry joints" or the wide silver cable (LCM) needs to be re-seated on both connectors.
Disconnect the battery before fixing LCM cable. Here is advice on USB port repair.
Replacing the daughterboard PCB should be the last resort because it is unlikely that the touch function will work 100%. It would work if we had access to the touch calibration software - the problems are described here https://forum.xda-developers.com/ne...rivers-to-calibrate-touch-screen-usb-t3334898

I doubt re-seating would help or cleaning USB port, since it was something electrical happening with that *puf*. If my memory serves me right there was a smell of burnt electronics. I doubt that some shortage disconnected any cables.

Sounds like you need a new charging port and board. Easy to fit but difficult to get hold of one. Maybe purchase a broken Flo on eBay and extract the charging port board

Even tho charging works? The only problem is data part of USB connection. USB OTG will not work neither will it connect to a PC for file transfer/adb. But if connected to PC or plug device charges. I believe it will not charge past 80 or 90%.

No USB Options Anymore

Hey all, I'm having a really weird issue (Google searches give nothing but the static/generic answer on how to access this area), where my USB Options are no longer there, when I tap the three dots, in the Storage area.
Stock Firmware, Android 6.0.1, Rooted using TWRP Recovery. I've never had an issue with this before, and it was working fine a week ago. No new apps installed, since then.
When I plug the device into my computer, it says charging, but no other USB connection.
Any one have any ideas, as to why or better still, how to get it back?
Thanks
EDIT/UPDATE: I did a factory reset, and it's still not there. I can't even completely wipe it, and start fresh since I can't access it at all, from my PC.
I had a similar issue. The tablet stopped charging and the data connection was being interrupted all the time.
It might happen that the female micro-USB connector (on the tablet) becomes unfirm/loose after some years of use. The micro-USB connectors are well-known to fail after some years, because there are two pins that fix the male connector inside the female one. They get loose over time. This is a general frailty of female micro USB connectors in all devices.
- Try an other usb cable. (Better: try out different cables, perhaps one will work.)
Also, the female connector might be dirty. There might be debris on the contacts.
- You can try to clean the female connector (at your own risk!), I did it carefully with a tissue soaked with ethanol.
In theory, it might be possible to replace/repair the connector if everything else fails.

Rooting and installing a custom rom without working USB.

Hello,
I have just found my old Nexus 7 2013 and I want to bring it back to life, but USB Port does not work (I charge it via wireless charger). Is there any safe way to root it and install a custom rom(I hope it will make my device run faster than on stock 6.0) without working USB?

I don't know of a way to root or install a custom rom without pc access.
I have an N7 Deb which lost USB data connectivity and I found that the problem was caused by a ribbon connector on the left side of the motherboard when viewed from the rear, which is the board at the top of the tablet. The ribbon cable involved carries USB data, battery charging current, screen touch data, and for the LTE Deb version of this device, SIM card data. I had opened my N7 and replaced the battery, which required me to temporarily disconnect the ribbon cable from the motherboard. When I got everything back together I had no working touch input from the screen. After some research I found my problem to be the ribbon connector on the motherboard. Applying pressure on this connector frequently remedies any problems it may have. In fact, the rear cover has inserts which apply pressure on two ribbon connectors on the motherboard. If you remove the rear cover from your N7 and press on this connector while your PC is connected to it, you may find that connectivity gets temporarily restored while you are pressing on this connector. If this is the case, you can experiment with adding some additional cardboard between the rear cover and the ribbon connector to permanently add some additional pressure to this connector. If this works, you can then install a custom ROM on your N7.
Good Luck
