I wanted to unroot and reinstall the factory rom. However, i wiped and formated everything in recovery first. I am now stuck with a paper weight. The tab is able to get into recovery and into the bootloader but that's it. I connect it to the computer and it does not detect it. I have tried with an otg cable, but nothing. The port works as it is charging, but it refuses to connect. As there is no way to get a rom into the tab or fastboot to recover it, i think i officially bricked my first android device. Normally, my devices have an external sd card slot and i can put the files on that but not this one.
Can you not use your otg the same as if it were an external SD? That's what I do all the time in twrp.

the device doesn't recognize anything. I think the data port on the micro usb might have gotten fried. there is voltage getting to the device because it is charging, currently at 100%, but if i connect to the pc in either bootloader or twrp it isn't recognized. I also tried to do the otg but twrp still gives me nothing - states 0mb otg. if the board would have been cheaper i would have just bought another just in case it was that but the cost of the board is as much as a used tablet.
Make sure you're mounting the USB storage in TWRP after plugging it in: Mount > Check USB-OTG box (I've had to uncheck and check the box several times to get this working before).
Also, I'm not 100% sure on supported file systems in TWRP via usb-otg, but you may also need to make sure the USB storage you're mounting is in FAT32 format and not NTFS.

Somehow I ended up flashing TWRP. Now my phone can only get into this and not original android. My phone also won't connect to the computer, windows tries to install the drivers but they never install successfully. Any help is very very appreciated.

Try going to mount and storage and click something that goes around USB mount/usb storage. I think its mount usb AFAIK, this should start USB MASS STORAGE mode and youll be able to transfer files from your computer.

But if like me when you try this, TWRP fails to mount.
Only other work around I have found is USB OTG + Memory stick with ROM on it.
Plug in switch to "Use External Storage"
Find ROM
Flash.
I'm unable to mount in the latest version. But if you flash version 2.4.3.0 you should be able to mount again.

Hi,
I recently bought a USB OTG cable and an "Integral USB 2.0 Single Slot SD Reader " so that I could use my Nexus 7 to view photos from my camera.
At first I tried using Nexus Media Importer to view files on the device, but this did not work. I have successfully been able to use this application to mount a USB thumb drive via the USB OTG cable.
I then rooted the device and installed stickmount. This did not seem to work either and there were no signs that the device was recognised by the tablet (the red light did not come on). I configured stickmount in SuperSU so that it has root access. I did not copy any data or apps back onto the device after unlocking it, and I am using the stock android 4.4.2 ROM.
I tried mounting the SD card using the card reader and USB OTG cable with my Galaxy S2 running Cyanogenmod. This mounted as soon as I plugged it in so I doubt there is a problem with any of the components.
I have tried mounting the drive both with USB debugging enabled and disabled. Is there anything else that I can try?
Thanks,
Ciaran
Reboot your device while keeping the OTG cable connected.

Thanks, this does allow the drive to mount successfully; however, if I remove the drive then re-insert it it does not remount, nor does it show up in Stickmount. Is there a way to remount the drive on-demand - just like my Galaxy S2?
You can press the 'thanks' button if it helped. Till now, I have not come across any such method to mount the OTG cable on demand. It's a cheap ploy by Google and Asus that they do not allow native OTG support on the Nexus 7 2013. Just to promote the cloud services. Mounting OTG cable is so easy on the Moto G and Samsung devices. It's a given these days.

It's gotta be the connections your using. Either the Integral SD Card Reader, or the OTG cable you are using. I never have any issues using stickmount with my Meenova MicroSD card reader. Have you tried other adapters?

^This, stickmount mounts my meenova as well as my OTG+USB thumbdrives on demand, no issues whatsoever, no need to reboot or anything, it just automounts and it's ready to go.
I never managed to, clicking on it does absolutely nothing.
It's quite annoying because i cannot copy stuff to my tab from recovery, i have to use ADB command line instead..
Is it just me?
Edit:
Latest TWRP ofc, 2.6.3.1
Anyone? How do you copy stuff in recovery without ADB?
For accessing files on my USB I use Stickmount and can copy files with my File Manager. I can also flash Roms that are on the USB with TWRP..

But you are talking about app , when you are booted in Android correct?
I'm talking about moving stuff to sdcard in Recovery. e.g. connecting it with my PC in recovery using USB cable wont show me any storage in "my computer", and mounting "USB-OTG" does nothing.
I have no problems copying stuff when i'm booted in Android, storage is properly detected/mounted.
But in recovery i have to use ADB to copy anything to my tab, is there solution for this?

You can't mount to your computer in TWRP. USB-OTG is something different.
Yes I do it all the time. I only have the 8GB so I use USB Flash Drives, or microsd cards through an adapter all the time. I have 3 cheap USB OTG adapters I got from eBay. And one Meenova SDCard adapter. But I use micro SD's with a USB adapter with the USB OTG cables as well.
I pretty much always do this when I backup in TWRP, or am Flashing a rom.
There is two ways to do it really.
One. Go to the advanced and select Mount. On that page I just unselected everything and select USB OTG. Then you don't have to do anything else. Its just like when u select the radiobox it is marked as being mounted, you can then access any files on it using whatever means depending on the circumstances, it will be located at the root of your device, at the bottom there is a dir named 'USB-OTG' select that and your files should be in there.
The second way, go to mount, but below all the options there is a box that says 'Storage 1xxxxx mb'. Etc. Just tap that box and it let's you select either USB-OTG or the devices storage. I use this option to make a band backup so it just defaults to a TWRP/Backups/ dir on the drive. Instead of having to fiddle with all that backing up to get to a custom dir.
It should work. There is no indication that it is mounted if that's what you mean, unless there is an led on your drive of coarse.
Just head to the root dir and USB OTG should be there and you be all good.
But yeah your computer is not a hard drive so you can't just mount it like one. You could technically if you took your hard drive out and connected it with adapters, but a Flash Drive is like $5 these days for one that can hold even the biggest of files you would ever need in recovery.

All you have to do is, Re-Format the MicroSD card in your computer (I use windows 7) using SDFormatter v4.0. Click the "Options" button and for "Format Type", Select "Quick" and for "Format Size Adjustment" Select "On". Thats it! And it will Surely be recognized in TWRP (i use v2.7). Hope that helps.
I have exactly the same problem. I have flashed a number of ROMs from a USB stick via an OTG adapter.
But now the tablet has stopped recognizing the USB OTG. As the tablet (a Nexus 7 Grouper) has no SD slot, there is no way of transferring the ROM files. So I'm stuck.

I never got TWRP to see the OTG if I inserted it whilst the tablet was running. Only when I booted with OTG did it see it.
If you are using an adapter, say USB-A to USB-micro then some don't work well.

Thanks for the reply
I just use a small otg adapter, usb c male on one side and regular usb female on other side.

I'm having this same damn problem. TWRP really sucks ass on mounting USB-OTG... sometimes it works and most of the time it doesn't... I don't know what to do either when I can't load any ROMS on there!!
Anyone know a custom recovery that will allow me to do nandroid backup straight to a usb drive I have tried cwm, twpr,and philz and none seem to allow this.
yes i have mounted usb in the recovery but the only option to save is to sd card any help I know i am missing something stupid.

I could be wrong but if use CWM with an OTG cable it should work fine. In CWM you need to mount your "external sd".
After the backup is done; boot up, open a file explorer, have the OTG cable plugged in and go to /sdcard/usbStorage/sda1 and you should be able to see your backup there.
Remove the MicroSD card before proceeding to do anything to avoid any issues with the OTG cable or Flash Drive.
I believe TWRP has an OTG mount mode as well.

Yes i have tried in all of them to mount the usb drive but none have the option to save to the sda1 "usb" its weird i use twrp on my htc one and it does it on there i also used cwm, twrp on my droid x2 and they did it there i also have tried multiple usb sticks from 4 gig 16 gig 32 gig 64 gig and a 128 but no luck. I mean its not that big a deal i can copy it off to my computer but would be nice to be able to do it direct
OK, so for months now I have done everything from buying a new cable, battery, fully erasing both internal and external (I have a card reader I can put my micro SD card in), reformatted everything, tried using other computers to connect the phone, and the list goes on.
I never thought about this until lately, but is it possible to put a tar ROM file on my micro SD card and install it by adb sideload it in recovery? My phone has just been having too many glitches and I'm sick of it.
Thanks!

I have the same problem with my note 4 and I build cm13 for our device so imagine how bad it pisses me off but anyways the only fix is buying a new micro USB port for the note 4 cuz something malfunctioned with ours and there's no way to fix it.
