No OS installed, boots to TWRP but PC does not recognise device - OnePlus 3T Questions & Answers

So I've got a 3T which currently has no OS installed, just the TWRP3.2.3-0. The problem is that every time I connect the phone to the PC, the PC will only recognise the phone as Unknown USB device (Device Descriptor Request Failed). Due to this I cannot use adb to transfer files to the phone or transfer files directly to the internal storage.
I have tried using Minimal adb but device isn't found, tried different USB ports and cables too. For some reason the recovery does not read devices attached to OTG as I have also tried to transfer files using this method.
Any suggestions as to what I can do to make my PC recognise this device? Thanks

first of all check your usb cable then use this op3/t tool
it will install all drivers, unlock, decrypt, install twrp and dm-verity issue solution

But I cannot enable USB debugging since there is no OS installed, however I have not yet tested this program.
The USB port was working normally before the OS was removed. This problem started once there was no OS and just recovery. Is there truly no other way I can transfer the ROM to the phone? Thanks for your help

while having TWRP installed pc should recognize your phone, if encrypted phone shows Oneplus 3 in my computer Location without showing internal storage,
Check your USB cable, then boot into fastboot(Boot loader By pressing Power & volume up button together while phone is in off state) connect your cable to pc and phone and run the tool, to install op3 driver select number from your pc
install driver (1)
unlock bootloader (3)
decrypt(10)
install twrp (5)
boot into TWRP from fastboot screen select recovery and reboot
Push superSU (7) (it'll copy superSU into internal memory) install supersu otherwise phone lose root and go back to encrypted state and you cant see internal storage in pc
reboot into recovery and copy your rom, gapps and Magisk 17.1, install them
You are done now

Thank you for this information, however I get as far as installing the drivers but the PC still shows phone as Unknown USB Device (Device Descriptor Request Failed) and therefore the program does not find the phone. Tried this on two different PC's.

Go to advance in TWRP then click on sideload and flash the os using sideload command i. e. adb sideload filename. zip

Since the phone is only recognised as Unknown USB Device (Device Descriptor Request Failed) in the the win10 Device Manager, fastboot devices does not find any attached devices and I cannot transfer files through ADB.
I have tested the cable I am using with another phone and I was able to transfer files to the other phone using the same USB cable.

I have tried using USB OTG but the recovery does not detect my connected usb drive. Regarding sideload, when I boot to recovery and select adb sideload, and connect the phone to my PC I get a USB device not recognised message. The commands adb devices and fastboot devices do not list my phone.

Try this guide if your phone detects as Qualcomm in device manager then proceed otherwise check your charging port (type c port) as you mention usb otg didn't detected and usb cable worked with other phones.
don't forget to clean your type c port if dirty or rusted. :good:

[Q] Mac won't detect my Nexus 6 (or other devices)

Since Google recently released the second preview of Android M, I've been trying to sideload the OTA through adb. The problem is that my Mac won't recognize my Nexus 6 whenever I plug it in. I have debugging on and change the USB mode to MTP, but still no luck. However, when I change the USB mode to MTP, Android File Transfer recognizes my Nexus 6 and I can go through my device's file system. I've also connected my dad's droid razor m to see if the problem only occurs on my device, but the same thing happens to his phone, too. Since I had no luck on my Mac, I tried to sideload the OTA on my Windows 7 desktop. adb only recognizes my nexus 6 when I have it booted up regularly, but when I put it in recovery mode, my desktop makes the sound that signals it can't connect to my device and it won't show up in adb, either. Any suggestions? I believe adb is set up correctly on both my mac and desktop since I can execute other commands such as "adb version" and "adb help". Thanks in advance!
And here is the device information of my nexus 6 and my dad's droid razor m:
Nexus 6
32GB
not rooted
stock recovery
stock rom - Android M Preview 1
Droid Razr M
8GB
rooted
custom recovery (TWRP)

Just tried this out with no luck. Any other suggestions?
I've never used a Mac, so I can't help you there (but from my understanding, it should recognize your device as soon as you plug it in).
As for Windows, you need to install the Google USB driver found here.
Now, this can be a bit of a pain, but it is doable: Depending on how you are connecting to your device, the driver may need to be installed multiple times.
For example:
If you are connected with your device booted into Android, you need to install the driver;
If you are connected with your device booted into the bootloader, you need to install the driver again,
If you are connected with your device booted into the stock recovery, you need to install the driver again,
If you are connected with your device booted into the stock recovery and you select ADB Sideload from the menu, you need to install the driver again;
If you are connected with your device booted into a custom recovery, you need to install the driver again.
Always make sure that you manually install the driver, i.e., right click on the android device in Device Manager in Windows and select Update driver". Then do NOT select "automatically search for the best driver.. blah, blah" or whatever the option is called. Select the second option (something like "let me choose from a list") and then click the "have disk" button, and install it that way.

ADB won't see my BLU R1 HD

Hi. I've been trying for hours to get Helium backup to work with my R1 and it won't work. My G4 works fine with the same USB port and cable. When my G4 is plugged in, if I type adb devices, it shows up. The BLU phone does not show up. I've tried uninstalling and installing Helium in my computer and in the phone. I did a hard reset on the phone. I downloaded and installed the drivers Helium recommends and nothing. I simply can't make the R1 work. I've noticed a few people having the same problem in other forums but I haven't found a fix for it.
Anyone can give me some ideas? Thanks.
Did you enable usb debugging. Not calling you an android dummy but we have all forgot to enable usb debugging one time or uhnutha.
Yeah, I enabled it.
Another day trying to get adb to see my phone and nothing. I installed mtk drivers, etc and I'm still getting a blank when typing "adb devices"...
Are you using the cable from Blu? I noticed that my other devices work fine with any cable, but the R1 only seems to respond with the Blu provided USB cable.
Yeah, I started using the BLU cable just in case and it didn't make a difference.

Don't be so sure it's not driver, because while in recovery and while in system the phone reports different mode to PC, so could be using different driver
Try going into device manager in Windows and updating the driver. Select choose from available drivers, and if there's one that's different than what is currently loaded, try that one.

Vendor ID issue, you need to update the adb_usb.ini to include it.
I got adb to see my R1 under Windows. When you plug it in, change from MTP mode to PTP mode and unplug it, then plug back in. It works in PTP mode but not MTP mode for some odd reason.

What is the proper vendor entry. What is your entries. Currently I have:

ADB just "works" for so many users, It leaves the dumb question . Did you enable developer options and turn adb debugging?
Also what abd are you using?
Easiest thing to do would be reinstall adb + fastboot with 15 second install.
link to that is in the unlock tool thread. Which will also answer your question what is needed to install new / other rom.
(tool unlocks bootloader, flash twrp, can install superSU,)

Leeco usb transfer without os

Hey Guys,
I have been using my phone for the past 1 year. My Brother just Wiped Out My Mobile Phone completely though the twrp recovery. Now I am not able to transfer file from or through it. If I am able to do it. I can easily Transfer Rom File onto it and install it.
So Please Say A Way To Transfer File Into My Mobile Please which has no OS And is not being detected in my windows 10 PC.
You can use usb OTG from TWRP and change storage. Also if you connect your phone to PC with usb cable from recovery mode. Your phone shall be detected by your PC as MTP device. Also check if MTP is enable from TWRP.

Just open twrp and connect your phone to your computer. It should automatically detect your device as MTP. Alternatively, use an OTG USB Drive and install rom from it.

[Q] cant connect to pc in linux or windows

I recently bought a sm-t713 and i can't get my pc to recognize it in linux or windows.. i want to root and unlock the bootloader but odin cant even see it.. and its not an issue with not having debugging on. thats all turned on. Please advise. thanks!
Nobody knows why? I have oem unlock "on"
debugging "on"
But I cant get my comp to see the device..Have Samsung drivers installed. Still no luck.
How can I fix this? all it does is charge when I hook it to pc but can't transfer files.
sorry double post
Same issue here. I've had no luck sorting it out.

USB Debugging and MTP use different drivers and are different protocols.
Open a command prompt in windows then type:
adb devices
You should get a response with a serial number if USB debugging is working.
If so then it's likely an MTP driver problem or MTP isn't enabled.
In developer options under USB configuration, ensure MTP is enabled.
If so check the device is detected as an MTP device in windows device manager.

What the USB configuration is set to is actually moot. When the device is plugged in to a PC the tablet will bring up a notification stating what mode the USB port is in and also provide the option to change that to MTP mode (Transfer files), provided the drivers are correctly installed and all is in working order. By changing USB configuration to MTP the tablet shows up immediately on the PC but you still have to switch to "Transfer file" mode before you can move files between devices. Either way the results are the same and it takes the same number of steps. I always leave my USB configuration in "System Default" and I have never had any issues.

Thanks for helping! under device manager the tablet is showing as a mass storage controller not an mtp device. Even though in the tablet itself I have it set to mtp under developer options.
When I do the command "adb devices" I get this message
C:\Users\Brian\Downloads\platform-tools_r28.0.0-windows\platform-tools>adb devices
List of devices attached
nothings there
Also I was reading this is happening because of the newest stock update from Samsung.. is that true?

No response from the adb command suggests you don't have the correct adb drivers installed or the device isn't being detected at all.
Have you installed the ADB drivers?
I would try a different cable first. Is Windows device manager detecting the device if it's plugged in/unplugged?

Still having trouble here, too.
After flashing a ROM and attempting to install what was probably the wrong Gapps version, I'm now getting a boot loop into TWRP, and the device is still not recognized. I can boot into 'Download Mode', but the device is still not being seen by my PC. I have tried multiple times to install the USB drivers, but Odin 3.12.3 is still not seeing the tablet.
Much as I hate installing hokey, bloated software, would KIES be helpful here?
So, all is not lost (yet) - I can still access TWRP, but I'm not sure where to go from here.
Thanks in advance for any ideas you have.

Considering download mode is totally OS independent and neither uses adb nor mtp drivers it seems the issue is either incorrectly installed usb drivers or faulty cable, device or port issues.
Boot to Download mode, open device manager then plug in the usb cable.
Windows should detect the device as a USB composite device.
If there is no detection then there is a communication issue between device and PC which could be any one of the afore mentioned reasons.
No matter what windows should show some sort of detection as soon as the device is plugged in.
No detection means no matter what drivers are installed its not going to work.
It's probably worth uninstalling the usb ports then rebooting.
Then trying again.

Detected in ADB when phone is on; not detected in fastboot

I'm about to convert my phone to the WW rom; but I am at an impasse. Any help would be greatly appreciated.
My phone is unlocked as verified by the security message and I can get into fastboot. I have developer mode and usb debugging enabled. When the phone is on, and also when in recovery; the phone will return the serial number with the adb command. When I reboot into fastboot, the phone is no longer detected. I have tried a USB A to C cable, USB C cable, and a combination of USB C, USB 2.0 and USB 3.0 ports on my computer. I have used both the side (blue) and bottom USB ports on the phone, but to no avail. Other odd confirmation is in the device manager my phone shows up as ROG Phone II, but under USB. I'm not sure if it is detected right; the screenshots I saw showed it detected as a device under another section in the device manager.

I'm about to convert my phone to the WW rom; but I am at an impasse. Any help would be greatly appreciated.
My phone is unlocked as verified by the security message and I can get into fastboot. I have developer mode and usb debugging enabled. When the phone is on, and also when in recovery; the phone will return the serial number with the adb command. When I reboot into fastboot, the phone is no longer detected. I have tried a USB A to C cable, USB C cable, and a combination of USB C, USB 2.0 and USB 3.0 ports on my computer. I have used both the side (blue) and bottom USB ports on the phone, but to no avail. Other odd confirmation is in the device manager my phone shows up as ROG Phone II, but under USB.

I had the same issue last update. Something in a windows 10 update broke fastboot detection. Use another computer with an older version of win 10 or boot a linux distro.

I installed and used ADB into Linux Mint 20; but it ended with the same result.

Try installing this version of adb/drivers
https://androidfilehost.com/?fid=746010030569952951
Once installed, the adb folder in root of C contains a 'cmd here' file, makes launching a cmd even easier!

Plug your phone on side port and reboot to fastboot then use this app to fix fastboot mode
If you already plugged the USB cable to the side port and still not able to use fastboot, it is probably a Windows problem. The Android fastboot exe is not properly signed so you need to disable Windows' driver signature check before installing the ADB/Fastboot drivers.
I cannot post link but search for "android fastboot driver disable driver signature enforcement". Disable the signature check then install the fastboot drivers.
Here is the quick run-down of the steps.
1. In command console and in Admin mode, run this command and then restart => bcdedit /set testsigning on
2. Install adb and fastboot stuff
3. After successful install, in command console and in Admin mode, run this command and then restart => bcdedit /set testsigning off
For ADB/Fastboot driver, i use the one by "fawazahmed0" here in XDA. The title of the thread is [Tool] Latest ADB Fastboot and USB Driver installer tool for Windows.
Okay, I tried all of the above; fastboot is still not detected in ADB, but it is detected in Recovery and when the phone is at the home screen. I noticed the phone came up under "Samsung Smart Phone" or some such in the device manager. I uninstalled and reinstalled and now it shows up as ROGPhoneII. However, same result as before. I tried the install methods on a secondary Windows 7 machine, but with the same result.
