TWRP and USB-OTG

Hi there,
So I did something really stupid and I wiped my phone while in recover mode trying to install a new ROM. And now I'm stuck with a useless phone that can only go into TWRP and Firmware Update Mode.
I've tried every method to unbrick my phone, and have a previous thread on this forum trying to get help (http://forum.xda-developers.com/showthread.php?p=48914581#post48914581), but nothing is working.
My question now is I'm running TWRP 6.3.2.2, If I buy a USB OTG cable and put my rom files on a USB thumbdrive, can I then install the rom from the usb? If so, where in the filesystem does this usb storage show up?

I believe only TWRP 2.6.3.4 can support OTG (I've been happy with it).
I think you may have to ADB push the files from PC over while in recovery (may need to look around).

Oneplus 2 no OS installed

Hey guys,
Earlier today I wiped my phone while trying to update the system, but when I tried to install the update it failed. That means that I'm now sitting without an OS on my phone, only able to access TWRP Recovery and Fastboot. I've successfully installed adb drivers and all of that, but when connecting the phone to a computer ADB doesn't find any devices and device manager only sees it as an unknown USB device (Device Descriptor Request Failed). I have been seaching for a couple of hours now and have not been able to find anything that works, so I'm hoping that you guys can help.

When I try to update the driver, as it says in step A-7, the only unknown device is the unknown usb device and when I try to update that one with the qc folder, it just says that Windows have determined that it is up to date?

Have you tried connecting to PC while in TWRP recovery ? You should be able to access internal storage using mtp. Then you can copy another rom & flash it.

I have tried connecting to Windows 8.1 on a Macbook Pro while in TWRP Recovery, and that's where it said it was an unknown USB device.

Any other ideas, because I do not own any other USB type C cables. The one I'm using is the one that came with the phone, but I have never had any issues with it.

Lets try installing the drivers again. If this doesn't work, then it should be a cable issue OR usb port issue. Try this on another pc.
1. Download Oneplus2 USB drivers -> https://www.androidfilehost.com/?fid=24052804347833370
2. Before installing the drivers, Disable Driver Signature Enforcement. -> https://www.youtube.com/watch?v=NM1MN8QZhnk
3. Install the drivers & Restart.
4. Now try either connecting to pc while in TWRP or fastboot.

you can flash factory image through fastboot

Maybe this is a bit annoying but the best solution is to buy another cable since a few weeks ago I had the same problem, bought a new cable and the problem was solved. Hope this helps
Then flash the OS through TWRP using the advanced tool that allows you to sideload files using adb.

How to enter mtp on recovery/fastboot?

I've done the same thing in the past (erase everything) , the solution that worked for me is this:
1.Always have a twrp back up on a usb stick.
2.Buy a cheap usb 2 type c to usb adaptor.
3.Enter twrp and restore the back up.
This way you do not need a pc/drivers etc.
I hope it helps.

Looks like you haven't installed oneplus usb drivers. Install the drivers & try again.

Nexus 4 - Broken screen, no touch, need to unlock

Dropped phone, cracked screen, screen works but is unresponsive to touch.
Problem: Need to unlock to access data. This seems to be a common problem but I've been reading the forums and still cannot find a solution
Status:
- USB debugging disabled (presumably)
- No OTG support
- Not rooted
- ADB, running adb devices command shows no device
- Booting to android screen shows Secure boot: enabled, Lock state: unlocked (not sure what this means)
I've tried Vysor and k.janku1's tool, both don't work as presumably the USB debugging is disabled.
Is there any way to enable USB debugging? Or is there any way to connect to ADB? Or any way to flash CWM without ADB?
Any help would be greatly appreciated!!

What data you want to access? May be you need to see if you can boot in to fastboot mode, flash a recovery and then take it from there.
If you are able to do that then you can connect your phone to PC and access it as an USB stick.

Thank you!!! I have flashed the CWM recovery and can access it on my phone. Where should i go from there? I have tried 'mount USB storage' but the phone is not being recognized on the computer still, I cannot see the storage. I am trying to access mainly contacts and photos. Thanks again!

Try flashing twrp it has mtp mode

Your contacts should be synced to your google account. Get them from there.
I do not use CWM as it is not supported these days (although it was my favorite recovery back then). So can't help you. As @[email protected] suggested, flash TWRP.

Thank you both, TWRP worked and I could connect it as USB storage to my computer!
Another question is, would it be possible to enable USB debugging through adb/CWM/TWRP? So I can use those tools to control my phone via computer.

No, that's not possible as far as I know. If I were you, I would have flashed a custom ROM which has USB debugging enabled (Like NitrogenOS)
Don't know how can you flash that without touch. Check if some connector like this allows you to use your mouse with the phone.

USB not recognized by PC or OTG

Has anyone faced this problem where the LePro is does not connect to the PC anymore? Charging works but otg and PC connection don't work anymore.

My brand new had this bug, first wipe resolved it.

Was it the exact same problem? It would charge but no connection with the PC and no USB otg?

I dont have any OTG devices, so I dont know. It was on stock ofc.

Had it, wouldnt even charge. A combo of plugging/unplugging multiple times, w/rebooting enabled me to charge it, then i flashed the official 21s or 19s, dont remember now, and it started working. Also, sometimes just reversing the cable (phone side) did the trick.
Try rebooting w/ different cable and see if that helps the pc connectivity issue.

I'll try that, but it seems that there was glitch in the current some sort of fluctuations and it maybe fried post of the USB connector. The thing is I simply can't root and install any custom ROM other than that it is perfect. Thanks for sharing!

Nope... Sold it to someone who claimed to be able to fix it. It's a shame, I loved that phone.

I've just received a "new" Pro3 from Aliexpress which has this exact problem. Although it looks new, the dust and fluff in the USB connector gave away that it's been reconditioned.
I have another 2 of these phones which connect to my PC fine.
The PC doesn't even detect a connection with this one though.
Now I can't unlock and replace EUI with LineageOS. I'm not going to use EUI.

I have the same problem. It is charging but cannot connect to pc. It must be a windows 10 problem, because with windows 7 it connects ok.

Your issue is just the driver, update the drivers on the PC and you will be fine. Also make sure in developer options that usb debugging is turned on and default usb settings are on file transfer mtp.

I have written these instruction many, many times. the answers are here if you search.
Remove all external hard drives from PC
Update PC
Install All in One Tool, use AIT to update android/leeco drivers/adb fastboot/enable system wide privileges.
Enable developer options> oem unlock, adb debugging and file transfer (MTP)
If in TWRP Recovery, the system must be mounted to be seen by the PC
If the drive is encrypted > it has to be formatted ( Not wiped) Reboot to Recovery > Issue resolved
Read the signature, its highly applicable

Okay, try using an older version of Twrp Recovery. ( A Non Treble Version)
Use OTG if you have it. Otherwise place te TWRP image on the SD storage > When installing your will need to select install IMG ( instead of zip) Install to Recovery, Reboot to Recovery. Click Mount, select data, and erase all of the encrypted data on your phone by choosing Wipe, Format > type yes, Reboot to Recovery. ( check boxes) you want the the phone to be read/writable.
At this point go to File manager > SD Card> You should only see a TWRP folder > Fo to Wipe Advanced wipe, select everything except your OTG drive > Wipe > Reinstall your Rom, Gapps, and Magisk. Did this work?
If no,
Reboot to TWRP recovery
* Select Advanced Wipe
* Select "Repair or Change File System".
* Select Change File System > Even if its already ext 4 select it again
* Format Data> Yes. Reboot to recovery > Full Wipe > Finished
* Now /data is mounted back. > You should be able to install whatever you want. > hopefully > if not you may have a hardware issue, such as the usb card, flex cables or worse.

@tsongming Good morning friends I have my Leeco Le Pro 3 with no system installed, just twrp working. When plugging the otg or the PC he does not recognize anything, I already bought 3 otg and tested with 4 cables and more than 5 flash drive, all this and without success. I installed all the necessary drivers from which, downloaded the tool all in one, tried the qfil mode, but the phone is not recognized on the PC. Has anyone managed to solve this problem?

I have 3 X720 and one of this has got the same problem.
TWRP 3.2.1.0 could not recognize OTG USB and Internal storage. Now Lineageos doesn' start . The start is in loop.
PC doesn't see X720 also in fastboot when the other two in fastboot works.
I think it's a hardware problem!
I have also chankged Micro USB Charging Dock Port Charger Connector, but nothing is changed.
How could I make?
Thanks

Is your charging problem resolved ?
In my case the phone won't charge anymore.
Do You think that changing the dock port will be the solution ?
Is the change difficult ?

Mtp not working in recovery mode

Hello
I am having issue with mtp in recovery mode for twrp
When I enable this. My computer does not see my phone in windows. I get the mtp device with the exclamation point in windows and am not able to see my phone to install anything.
I can only do adb sideload to install my apps. Mtp is fine when I am using it normally on my computer when I am not in recovery for twrp.
For additional information this is also happening when im on windows 10:
USB debugging disabled - MTP working
USB debugging enabled - MTP not recognized

Try this, this work for me. Saved my X727 after encrypted and format Everything.
https://docs.google.com/uc?id=0B9ZMWt4u_wSDVkp3UlMxS1liMUE&export=download
Flash it via Fastboot and re-flash from recovery (install/Image and choose "recovery".) Now you will see your Smartphone like a drive on your PC from recovery.
Hope works for you

Would this wipe my rom and data?

I don't know if this is a hardware or software issue. I was having issues syncing my phone with my computer. The computer kept freezing while I was going through my phone's files on it. But I found that switching my USB-C cable for a better one (a Benson-approved one) fixed the issue instantly.
