Help! Otg on Lenovo A916 - Android Q&A, Help & Troubleshooting

I buy a Lenovo a916 phone not long ago;most of the phones have support for otg,so I tried in it,but it didn't work. I tried using different tools and procedures: I rooted it using Kingroot (it makes the phone really slow), and used differents apps, like SMP,version 3,25; USB OTG Helper, and USB OTG checker. I checked my phone, and there were two errors. I manually fix them (using es explorer, changing permissions and modifying some files), so the app said that I can connect the otg devices, but... nothing happened. Maybe I did something wrong. Can anyone help me? thanks.

[Q] OTG/USB Host for MT65XX Phones, especially for Jiayu G3, possible?

Hi folks!
I need the OTG/USB Host function on my Jiayu G3. Normally it doesn't support it..
So I did i lot of research and tests at "how i can enable it" and found some information:
1. some things point to it, like the libusbhost.so in /system/lib
2. all 5 pins of the usb slot are connected to a chip (this says nothing, i know)
3. i have found a pdf, which says that otg is possible on mt6575-77 (found on github)
So my question, has anybody get otg/usb host get enabled on Jiayu G3 oder m65xx phones? OR is anybody there who want the same like me and helps me to make it possible?
OTG unlock
Hi
I have a similar problem with my Jiayu G3s (MTK6589T).
For most USB devices it does not react but i hope there is a chance to make it work.
I do not know if it si trustworthy but according to USB OTG Checker my device supports USB OTG.
When i insert one of my USB flash drives i can find sdcard1 folder (total commander) . It is empty but it reacts.
Can anybody please help or just explain what is the problem. Thank you

Hi there,
I think I have a possible solution for this case.
Many USB cables are not correct to link with computer. I have two cables, one of Jiayu and other (more thin) brought in a chinese store. The cable brought in chinese store don't work to link with computer.
I hope this information was useful.
Any updates?

This might help. Using an apk it is possible to make it work, IF kernel supports it. Don't know if phone has hardware support though...
I've read here that you should connect the ID pin to a pull-down 150k resistor, then to GND.

Copying files from W10 to the Le Max

Hi all,
I'm having trouble with copying files to the phone. When I connect it to my PC via USB The device pops up in explorer, but every time I try to copy something it fails. When I try to copy entire folders (I'm trying to copy Flac and MP3 music) W10 gives an error that it can't copy the files. When I try to copy files, it shows the copying dialog, but nothing ever happens, however long I wait. I've tried debugging mode, uninstalling Kies, Uninstalling the Samsung drivers, installing ADB drivers,... nothing seems to work. If anyone has any advice, it would be greatly appreciated.
I've also tried a new USB-C 3.1 cable, to no avail. I'm using the USB 3.0 port. When I try an USB 2.0 port with the USB 3 cable, the phone doesn't show up. Which is weird I guess but maybe due to the nature of USB-C.
CHeers
I forgot to mention that I tried copying a picture from the phone to my pc, which worked perfectly.
Hello, I know your message was time ago, but I have now exactly the same problem with a Leeco LE 2, also with C-type USB, and searching for some solution I have found your question. ¿Did yoy manage to find the way to fix this problem?
Regards

You probably connected your phone to the PC as Camera(PTP).
When you connect your phone to your PC, the USB symbol should appear at the top of the screen. Swipe your finger from top of the screen down you will see the USB symbol saying USB for charging. Click on it you will see the 3 connection options, pick Media device(MTP) and you should be able to copies files between your PC.
Thank you for your response, but I'm afraid that this was right, I tried it with the MTP mode enabled.
me too i have problem of copy , I can transfer files to the phone, but I can not copy from the smartphone to the pc
MTP and usb debug is actived
i cant recover my TWRP backup
With version of software do you have?
Running 21s build with Server2016 and when I tried to cut the /DCIM/Camera directory frome the LeEco it just deleted it. Ughhhh.
Did you manage to solve this?
I'm in the same situation. I can't copy mp3 files to the internal memory of the device.

USB On-The-Go functionality for CM-based ROMS

I'm not sure whether I'm having hardware issues, but USB OTG function doesn't seem to work when I'm trying to connect a flash drive to my phone (XT1521). I've tried this on both CM13 (August Nightlies onwards) and RR 5.7.4. Previously on stock rom (6.0), USB OTG works okay when it comes to flash drives. Nowadays, my phone doesn't seem to detect flash drives, though it could detect other input devices, such as mouse. Please note that the flash drives are using FAT format. Is there anyone who's having the same problem? I'm really wondering whether this is an issue with CM-based ROMS for Surnia, or it's just my phone. Any helpful info would truly be appreciated.
well, Ive used cm13 and have been able to connect the pendrive using otg and was able to view the files. Try this=>
download es file explorer and then slide for the side menu and u will find a tab named "local", click on it and u will find the usb device connected. Click on the name of the usb drive and u will be to access it..
Note: Ive tried numerous apps but none except es file explorer could detect the usb device.

I've just downloaded ES File Explorer and did what you've just said. Sadly, there's nothing. :'( I do see the point of using ES, as some USB Drives seem to be rather picky with file explorers, even with my Xperia M back in the days. Is there any prompt appearing in your notifications drawer when you plug in your drive? I get nothing. ?

I was always able to access my USB in CM-Based ROMs though ES File Explorer.

Kindle Fire 2 CM 11-XXX USB OTG

Hi guys I am new here and new to this whole rooting, custom ROM thing. This all started from a need of an android device to run an app for a motorcycle efi tuner. It connects through a USB cable and allows me to change some tuning parameters in the module. I have never owned an android device, but I did own a Kindle Fire 2. After doing some research I stumbled across tutorials on how to install CM and make it an android device....and that where I am at now.
I have successfully rooted and installed CM 11-20160815-NIGHTLY-otter2, android 4.4.4, Kernal version 3.0.72+
Now the problem I am facing is the use of the usb cable to link the tablet and module. I have a USB OTG cable and after some research it looked like I needed a powered cable, so I made one of those too. I have installed Stickmount, USB OTG helper and USB OTG Checker. Running the checker I see that my device has the USB OTG API.
The interesting part now is when I connect the powered cable to the module and Kindle it will open the app automatically but it says not connected. The weird part is that it detects it enough to open up the app. Also I have not been able to mount through stickmount.
I am not a developer and not familiar with a lot of the lingo so at this point I am stuck. I don't know what else to try its over my head at this point. A google search turns up very little on this, although I have seen youtube movies of it working so I guess its possible.
Any help would be greatly appreciated!
Anybody have any ideas? I don't have enough post to put this in the kindle forums is it possible for someone to move it there?
