Use win 7, when the phone is connected to computer reboot your phone without unplugging ..

[HELP] Can anyone suggest a kernel with OTG and charging at the same time features

So, guys can anyone suggest a kernel or a rom which enables using the OTG device while charging? I use a modified version of a powered USB hub (found on Internet).
When i try, it either charge the phone or enables the OTG host mode, whichever is tried first. Not both at once. I searched the Internet and found there is a kernel patch for nexus and xperia devices. So can some one get me the the link of a kernal or rom which can use the OTG while charging....??

Please Help!!

I'm not 100% sure but i think since i updated my Z3 Compact to MM via my phone updator i haven't been able to connect any flash drives via OTG. now the thing is in setting > USB Connectivity , the only option is Install Software while i have seen couple of other options in other phones in 6.0.1
is it possible that if i re-install the stock rom (6.0.1) via my PC the problem would go away??

You should be able to connect flash drives via OTG.(File Commander recognizes it well on my 6.0.1 firmware)
As for the USB Connectivity setting, it changed on 6.0.1 and 4 connectivity options will appear on your screen whenever you connect it to your PC when you connect it through your USB cable.

the problem is that the only option for me in USB Connectivity is Install Software. i think i should re-install the stock 6.0.1 ROM via PC. by the way OTG does't work. doesn't show any noticifications even.

Are you on 6.0.1? If yes, then Install Software is the only option you should find in USB Conmectivity settings! That's how it's built....sony removed the options and you have to choose usb Conmectivity whenever you connect your phone to your pc!
As for the USB,did you try File Commander?!

It could be a faulty usb otg cable...you can try using it on an other device and see if it works there. If it does,then your device has the problem, but unfortunately, I can't suggest you a solution other than flashing stock firmware.

Looks like your device has a problem then, or your usb otg isn't compatible with your device. Try reaching Sony Mobile Support once whenever you find time here.

USB OTG detection issue

Hi there,
I have this odd problem with USB OTG detection issue on my z3c
Android does not detect my USB OTG but TWRP recovery does. ( in recovery mode everything is fine)
TWRP recovery detects my USB OTG and I can do various operation such as exploring through using TWRP file manager or creating back up on this USB OTG and etc.
My phone has latest LOS 18.1 and I did change "USB CONFIG" in developer options to " transfer files" but still no USB OTG detection.
p.s.
when I bought the device it was working fine and detects the same USB OTG.
last year I gave my phone to some repair shop to re-flash stock rom as I had some software issues. After that I could not use my USB OTG on my phone....but back then I was thinking this is some hardware problem from charging module. recently I flashed LOS 18.1 hoping mentioned issue to be solved but still no USB OTG detection on android.
Seeking for any good advice as I`m frustrated and also disappointed little bit.
tanx in advance.

Good evening, I have a z3 compact purchased from a Chinese website. GPS does not work, and in some cases when I change the rom, I have this problem with OTG detection, in some cases in ROMs 5.0 and 5.1 it does not detect OTG in twrp. On ROMs above 6.0 TWRP detects OTG, I don't know if it has a connection with the TWRP version. But to view OTG content I use MIXplorer, I can view files, move edit...etc

Unfortunately using MIXplorer did not change the situation. It seems my phone feel nothing when I insert USB OTG. Not even a blink reaction.

Damn, this is not good. Today I flashed the MIUI 7 version. I think this version is beautiful, it doesn't support all current apps, but it's battery friendly. This cell phone purchased on AliExpress does not work the GPS unfortunately.
