[Nexus 7 Q&A, Help & Troubleshooting] fwayfarer:
go into device manager and delete every single entry that suggests anything to do with a phone, tablet, google device, nexus device, ETC. if you dont do that first, this will probably not work.

once you delete every single entry in there, go to the top command bar and somewhere in those menus is an option to show disconnected devices. delete everything again as above.

now, does your tablet still charge on the AC plugged into the wall? does it still charge when plugged into the computer usb? drivers are NOT required for usb to supply power. if so, the usb connector is probably OK. if not, your usb connector may be toast.

next, connect to the computer. does windows show any device connected? if not, try a different usb cable. report your findings back.
[Nexus 7 Q&A, Help & Troubleshooting] Waslow:
Sorry for the late reply.

There is nothing in the device manager related to my Nexus, which is odd, it had entries for flash drives, a camera, and my phone. All of which were in the disconnected devices. I got rid of just for the sake of it. Nexus charges just fine, either from the wall or any of my usb ports. If there is no way to make ANY computer see my Nexus, is it safe to say it's bricked?

I do have a cousin who's fluent in Linux if that means anything. I know that Android is a flavor of it. Might work better if both devices speak the same language. Grasping for straws I know.

Again, thanks for the help fwayfarer, GtrCraft, and Fobos531!
[Nexus 7 Q&A, Help & Troubleshooting] fwayfarer:
If I am reading right, you did NOT try a new USB CABLE yet, did you?

Try a known good USB cable, what I mean by that is try a cable you KNOW works for data transfer on another device and report back.

Connecting it to a Linux machine isn't going to make any difference in my opinion.
[Nexus 7 Q&A, Help & Troubleshooting] Waslow:
I have 2 cables and they transfer things just fine with my phone and my Kindle. I just downloaded everything off of both things, and transferred them back. No issue with the cables. I just popped open my Nexus and it looks like the usb connector and ribbon are fine. I did wiggle them a little but to no avail.
[Nexus 7 Q&A, Help & Troubleshooting] fwayfarer:
Pull the battery cable, smash the power button for a few minutes, reconnect and try again. It won't recognize a USB thumb drive in bootloader or recovery to my knowledge, BTW. I noticed you mentioned it not seeing one.
[Nexus 7 Q&A, Help & Troubleshooting] Waslow:
I unplugged the battery, hit the power switch for a while, plugged the battery back in, plugged the usb back in, nothing. Still nothing. I had read before that you can put the version of android you wanted on a flash drive. With an otg cable you could use that to update/install what you wanted.
[Nexus 7 Q&A, Help & Troubleshooting] fwayfarer:
You're probably right, I haven't tried using one in recovery for a long time. You didn't change the battery or anything recently did you?
[Nexus 7 Q&A, Help & Troubleshooting] Waslow:
Nope, haven't replaced anything in the Nexus. The only thing that I could think of that could be wrong is the usb connector. But for it to "fail" at the same time I formatted everything, too much of a coincidence.
[Nexus 7 Q&A, Help & Troubleshooting] Waslow:
Over a week bump
[Nexus 7 Q&A, Help & Troubleshooting] jadesse:
I ran into a similar problem about a year ago. Unless your tablet is connected to the computer you will not see it show up it the windows device manager. You should be able to connect your N7 to a work computer & it should go out for the drivers. If not, then you are Sol. You might have a blown main board.
[Nexus 7 Q&A, Help & Troubleshooting] Waslow:
The only thing my N7 does when I plug it in, is that it charges. That's the only thing I can get it to do. Well, this sucks. If I really have a bricked, or worse, tablet, it's still good for its screen and other bits.
[Nexus 7 Q&A, Help & Troubleshooting] fwayfarer:
Your flash memory is gone. New main boards however, are cheap.
[Nexus 7 Q&A, Help & Troubleshooting] Waslow:
What makes you think that the flash memory is dead? It still gets into the boot loader and TWRP. In TWRP I can still mount the internal storage, which it claims to be 28064 MB. There's no issue with formatting the flash. I had no problem with the flash before. Nothing corrupt or acting strange. Granted, I only had it for a few months and I didn't do much with it, other than read and watch movies.
[Nexus 7 Q&A, Help & Troubleshooting] Waslow:
Well, as an update I guess.

I ordered a new motherboard, it took a whole 15 mins to remove old motherboard, and install the new one. Honestly really simple if you know how the connectors work. Anyway, right now it's doing something the old board wouldn't do, update. so I'll leave it alone and let it do that.

Everyone who gave me advice, thank you! To those who read this and learned something, share it if the time comes.

Thanks again!
[Nexus 7 Q&A, Help & Troubleshooting] fwayfarer:
Glad its working. They're getting old, failures like this are expected.
[Nexus 7 Q&A, Help & Troubleshooting] Skylined:
Same thing with my N7 2013 after the battery went dead, gonna buy a main board from eBay but what are the chances it happens with the new one
[Nexus 7 Q&A, Help & Troubleshooting] fwayfarer:
it will eventually happen to every single flash memory based device on the planet. unfortunately we cannot yet defeat the laws of physics, and every single write/wipe cycle physically degrades the flash memory until it breaks.

Overview:

I’m a newbie to rebuild and compile a custom kernel. I like to learn new things and share with you my modified version of 14.5.A.0.242-Kernel

It is basically a mixture between some developers kernel source like e.g.,cocafe,DooMLoRD,alnikki25k.

I'm not a developer so I cannot answer your question about any bugs for this kernel immediately. I will try to ask other developer how to

resolve bugs. Experts, please correct me if I am wrong, this stuff is still new to me also.

i want to let you know that i have problems installing V18 and V18.1,my device sticks in sony logo and i think the problem is that i have data and system partitions formatted in f2fs(it works if only one of them is formatted in f2fs,i don t remember which one).

so please if you can and have time take a look at it,so i can use your kernel again,thanks!
[Xperia Z1 Compact Android Development] Frunzdoedel:
Argh, now i understand your proplem with newer kernel.

f2fs filesystem was recently dropped and i see no advantage to ext4 filesystem.
[Xperia Z1 Compact Android Development] t.daun:
As I mentioned before, I have the same problem, since v 17 I cannot install this kernel anymore. I don't want to recopy the whole data partition as on switching from ext4 to f2fs again. Maybe subjective, but I noticed a perfomance gain with f2fs.

So it would be nice, if the kernel can support f2fs again.
[Xperia Z1 Compact Android Development] Frunzdoedel:
Oh sorry i have to correct myself. Only f2fs system partition has been dropped, data and cache can stay f2fs filesystem, make a backup of your whole system, change the wipe thing in twrp, format the system to ext4 and restore the system partition.
[Xperia Z1 Compact Android Development] t.daun:
To make the confusion perfect:

/system patition is not on f2fs, only /cache and /data.

This works on v.16, but not on v.17 and v.18
