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.

Did anyone managed to mount USB-OTG in TWRP?

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!!

Question about recovery and usb

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

i think it's bricked

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.

Phone Bricked ?

Hi everyone !
Yesterday, I tried to install a new ROM (RR Android 7.1, the latest version).
I flashed the ROM with Gapps and rebooted the phone: I know the first boot is usually a bit long (15-20min according to my previous experience) but after 1h and no evolution, I decided to let the phone boot overnight.
This morning, it was still booting and when I plugged it to my PC and tried to transfer another ROM (to try again), it was no longer recognized ("the device has either stopped responding or has been disconnected")...
I also tried to plug the micro-SD card directly to my PC, it's not even recognized (nothing appears in the Computer window after being plugged, just the connect sound).
Drivers have been checked already.
So, basically, I have a OS-less phone that cannot receive any file from USB (mounted or not, MTP activated or not)
I still have access to Bootloader menu and Recovery.
Does anyone have an idea I haven't tried yet ? :fingers-crossed:

It's not bricked by any stretch.
First of all, you should have made a TWRP backup before trying to flash a ROM. You should always do this before a new ROM, root, or other mods; just a simple and golden "phone modding" rule to live by; so I don't know why so many folks neglect this step. If you had a TWRP backup, you could simply restore, have a working phone OS, and go from there.
When trying to read the MicroSD card, does you computer have a card reader built-in, or are you using a USB card reader? If the latter, try another, if you have one. They can be finicky, especially the cheap ones. You can even use an old working phone as an impromptu "card reader" in a pinch (I've done it a few times).
When connecting the phone to your PC, are you booted to TWRP when trying to copy/paste a new ROM? Can you connect by adb when in TWRP (you typically should be able to). If so, you can try to adb push a ROM, or alternately adb sideload a ROM.
Also, just FYI, if the phone is stuck for more than 10 or 15 minutes with no response after a ROM flash, you can conclude something is wrong, and go back into recovery, re-flash, try another gapps package (frequent cause of stuck boots after flashing an AOSP ROM in my experience), etc.

Thanks for the reply ! That'll teach me a lesson...
The SD card reader is built-in to my PC.
I'm always booted to TWRP when connecting my phone, just tried the ADB Sideload command but nothing happens (except FAIL). Is there something I'm missing ?

Try to reinstall HTC drivers, and whatever adb/fastboot tools you are using. Try another USB port, and another cable.
Don't see anything that should prevent adb or just seeing internal storage from working. Usually just a case of drivers, etc.
Another thing you can try, assuming you are using Windows, go into Device Manager, find the device, and pick the option to manually select drivers. Then pick the generic Android MTP drivers. I sometimes have to do this to get my home PC to "see" the M8 on adb or to browse internal storage.

By the way, when not mounted. The phone DOES appear in "Computer" window but can't trasnfer anything in "Internal Storage" and my SD card shows up as a ~16Mb storage capacity while it's a 64Gb model...

Well I can still browse the folders of the phone (internal and external storage), there's just nothing in there anymore.
I tried everything, thank you very much for your help and time but I'm still stuck

Internal storage not showing anything, may indicate the storage is corrupted. Try going into TWRP, select Wipe, and tap the "Format data" button; and see if that helps. Obviously, any data will be lost during the format, but I think we're past that point anyway.
Although this wouldn't explain why you can't see anything on the SD card. Internal storage corruption happens fairly occasionally. But I've never seen it coincide with SD corruption/issues. So that part has me puzzled.

This morning I tried another ROM (Lineage) + Gapps and it worked just fine using ADB Sideload !
I can't thank you enough for your help, I was about to give up and buy a new phone :laugh:
Thank you very much !
