[Q] USB Mount or Mass Storage not working on MT4G

The probem:
USB Mass Storage not working in Recovery. I tried everything, reflashing different recovery but its not working, it doesn't give an error message. When card is not inside however it does complain. SdCard is fine because I can flash zips that are on it. Tested on both windows and ubuntu. tried another card as well
USB Mount doesn't work in CM7.2 or any rom or nand restore i've done recently. I had Insomnia at some point, then inferno, then cm 7.1, none of these restores work. Again here no errors, I do not even see the sign for usb detection. usb debugging is enabled/disabled no difference. phone however still charges though.
I'm on a trip right now, but I've not had the chance yet to get another usb cable but the two I have dont work.

Its either your USB cable or your phone USB jack mine does the same thing I have to wiggle it to get a good connection cuz my USB cable sucks cuz with others it recognizes it right away.

He has tried two cables, so I would tend to lean toward the port.

i am in the same boat. looks like my charging port is bad. anyway to replace the charging port? i am not good with soldering

it's not ur usb port
it's htc.. htc devices doesn't support usb host feature.
If you have a rom and kernal that do support usb host then try powering the usb as the htc devices do not provide power out.. use usb Y cable

What? He isn't trying to host the connection. He is trying to use his phone as a USB mass storage device.
Where did you get USB host from in his questions?

Hi all,
I am having the same problem, except perhaps with a different cause. My user account on Windows 7 became corrupt and I can no longer log in, so I had to create a new one.
On the new account, my myTouch 4G is not recognized for mass storage/disk drive mode via USB. The USB cable does work, the port is okay, and I've used both with other devices. The myTouch shows as charging when connected to the computer. I have uninstalled and reinstalled all of the myTouch drivers, restarted computer and phone, to no avail.
When it is connected in USB, it shows as generic "Drive F" and is inaccessible. When I check properties it says mytouch4g. When I check "Devices" it is recognized as portable storage. I have tried with USB debugging on and off, and have set "connected to computer" mode to disk drive.
Any thoughts? I thought possibly loading the generic ADB driver again might help, but I cannot get to the stage where I can force it to load that driver instead of the HTC one.

USB error 43, can't figure it out.

My AT&T sgh 1337 Galaxy s4 has been a great phone, it was Loki'd back before the bootloader lock OTA's hit and I've been running CM11's latest milestone releases.
Lately I have had issue with my USB jack. When I would plug it in, I would just get an Error code 43 Unknown Device in windows, no device detected in linux & mac. I tried 3 different USB cables. I cleaned out the USB jack, didn't help. I did notice the interior of the jack was a bit worn and torn. It charges fine.
I went ahead and ordered a new USB jack/microphone board, verified the new part is specific and exact to the sgh-1337 model and installed it.
Plugged into a charger and tested, charging works, ~1300 mah draw on a 1.4amp charger. Looks good.
Plugged into a PC and immediately got Error code 43 USB device unrecognized. Still doesn't work. I changed USB modes in Settings>Storage>menu and, nothing. I enabled and disabled USB debugging several times. I've tested my machine with all samsung & ADB drivers installed and fresh machines, nothing. (Windows made the USB connect/disconnect sound between switching modes every time)
I installed Drivedroid (very sweet app for hosting disk images over USB) and used its settings panel to change USB modes, every single USB mode reports error 43.
Booting up into Recovery and mounting USB mass storage mode, same thing Error 43.
Booting into Download mode: Error 43.
USB OTG cable with mouse plugged in: nothing.
Is it possible that the USB controller on my phone's main board died? I hope not, that's unfortunate. It'd be hard to find a bootloader-unlocked motherboard replacement.
I read that an HTC user had the exact same problem, he reflashed his bootloader image from SD card and BAM, usb came alive again. I don't think that'd be a possibility with a samsung device though... hmm. Bummer, anyone think they can help?
I appreciate you reading.

wow, sorry to here that--could be hardware, you did about everything you could do--
Here are Google links which I am sure you already looked into
https://www.google.com/?gws_rd=ssl#q=usb+code+error+43+fix
Wild ideas--wipe your internal, reformat external or boot without it
Odin the MDL tar back to stock, keeping same bootloader
Odin and upgrade to NC1 with new bootloader
Use wifi apps for transfers
Not much help I know--just throwing stuff out there--:good:
Good Luck
Worst case lots of new phones out this fall--

[Q] Help unroot Galaxy S3 Neo GT-I9301I

Hey everybody,
two days ago I purchased a Samsung Galaxy S3 Neo GT-I9301I. (DBT Germany, no t-mobile branding)
I read that it supports USB OTG so I can use my phone to backup photos from my camera's memory card to a usb hard drive.
I did that before with an android acer tablet and that worked fine - but in the field a phone is even better when it comes to size.
Anyway, for testing I tried to get a FAT32 USB Stick 8GB to work on the SG S3 Neo and all I got was angry. It didn't work although I read on specification list that it has USB OTG support. OTG cable worked fine with the Acer tablet.
Ok, so I rooted the phone following this Tutorial primehowto.com/root-samsung-galaxy-s3-neo-gt-i9301i-easy-tutorial/. (Sorry but since I'm a new member I'm not allowed to post outside links.)
No problems with it.
With app "USB Host Check" I took care about android.hardware.usb.host.xml and handheld_core_hardware.xml. Now they both are enabled and shown in green.
"USB OTG Helper" for rooted devices should do the rest togehter with ES File Manager.
I even connected the stick via a powered USB hub because without external power the SG S3 Neo again didn't recognize the stick.
Then for a second it seemed to work but the USB stick connected and disconnected every two seconds over and over again.
After all these hours I think I'm just done with this phone.
I want to return it to the store where I purchased it.
BUT there is this system change counter and I wanted to know if anybody tried Triangle Away with the GT-I9301I to reset the counter?
In the rooting tutorial above it was said that "You can always regain it by following proper unroot process (for example, flash official firmware and then use triangle away)."
I found this tutorial theunlockr.com/2014/10/10/how-to-unroot-the-samsung-galaxy-s3-neo-plus/ about unrooting GT-I9301I but it doesn't reset the counter! :crying:
Or maybe I just forgot something? Please help me! Thanks!!
Alex

Where you read it supports otg. It can be fixed on kernel size. Problem.with USB otg is that it isnt outputing power to USB so it isnt powering on. You can buy other otg Cable that can give power to your USB untill we do hack on kernel.

Hi Rox,
thanks for your reply!
I read it here: inside-handy.de/handys/samsung-galaxy-s3-neo/daten
It's a German page put if you go down to USB port section you'll see a green check mark at USB-OTG.
The power problem was same with Acer Android tablet. But there I could manage it by connecting a powered USB hub with OTG cable to the tablet and then connecting an external hard drive PLUS a card reader to the USB hub. That worked. I could move files in all directions.
The thing is with the GT-I9301I that the external storage gets connected and disconnected every two seconds even with external power. That makes it unusable!
So what would you advise me to do? It can be fixed on kernel size?

Can you send me dmesg when that happens ?

Yes, sure. But unfortunately I don't know how to do that properly... Is "Dmesg Log Viewer" app the right choice?

It would be better to downlao dterminal emulator and do :
After you produce bug write in terminal:
Code:
su
dmesg > /sdcard/otg.txt
Then send me otg.txt from your storage

Thanks again Rox for your support!
Meanwhile I installed Triangle Away and its system analysis told me the counter is still on zero!
So I guess I'm going to flash back the stock firmware with Odin and get rid of all customized/modified settings.
At least that's what I read how to proceed unrooting in the article I already posted above.
I just don't want to spend so much time on enabling a feature that other devices have right out of the box.
Hopefully they take it back at the store without any further issues and I can look for a different, more suitable device for me.
Thank you Rox and the whole xda-developers forum! You guys are doing a great job!! :good:
Best, Alex

Other users reportrd that it is working with that extra supply Cable. Can you please send me dmesg for futher fixes ...

[Q] HELP with recovery, no usb access to nexus 7, not detecting with official cable.

Ok so long story short, i have a nexus 7 2012 which a rooted and installed cyanogen mod.
I was using it as a car install and works perfect, i'm using an otg cable to mount usb sticks, triggering soft shutdown and powering the nexus etc. So usb seems to be working fine.
Basically i removed the tablet it to modify the bootloader to turn on automatically with ac power applied, if the battery runs out i have to manually power on with button, but now i'm running into a problem.
Ever since taking the tablet out and trying to connect over usb, none of my computers detect the tablet.
I've tried different operating systems, drivers, cables etc etc.
Also changed from mtp to ptp in storage and also turned on usb debugging mode. If i connect an otg cable the nexus see's the otg and i can mount usb's etc.
So i thought i might try recover the nexus back to factory, maybe there was an issue with the rom corrupted etc, I've downloaded the original 4.2.2 firmware which is currently installed.
Booted into recovery and tried re-installing the 4.2.2 zip, it keeps aborting. A guy in work tried to use sideloader and connect via adb. no luck.
I'm not very familiar with the android platform so i've no other ideas what to do and other idea's how to recover now.
The guy i work with mentioned using a usb jig, would that be the way to go or can anyone else suggest some else that might help.
Thanks

Before you updated when was the last time you connected your N7 to your computer?
When you connect your N7 to your computer does it act like it is charging? Have you tried more than one computer? I had a similar problem with mine last year & sent it in 3 times. Asus replaced both the USB port board & the main board on different occassions. I suspect your mainboard might be faulty.

Does adb see the device

I last connected the nexus to the laptop a few monts back to load some music onto it, didn't have a problem. It's only been connected to a computer maybe 3 times. once to root/rom it then another few times to load music etc.
I can't see why the usb board maybe faulty as i can read data from a usb key when the otg cable is connected.
It's a strange one. You could be right, i might try pick up a broken nexus and swap some parts. Usb board etc.

Yes adb is shown in device manager, but it's not recognizing the nexus, comes up with an error 10 , cannot start. etc etc

I am having this same problem on my (unrooted) HTC One after attempting to "convert" it from an AT&T to a Google Play Edition device with the procedure described here.
As part of the procedure, I attempted to flash the stock Google Play Edition ROM using fastboot commands, but I got an error message. The instructions say to just try the flash again, but the phone no longer connects properly via USB (error 10) while in bootloader mode. While in bootloader mode, the phone indicates there is some sort of problem (a line showing the OS version is highlighted in red), and attempting to enter recovery mode does nothing but display a phone with a big red X in it. The phone seems to operate fine and responds to ADB commands when the phone is fully booted, albeit with the old OS (not Google Play Edition) still in place.
Any Android device could theoretically get in this state. We're sort of "paralyzed", because everything we want to do to regain control of the bootloader and fix the situation seems to require issuing fastboot commands from a computer connected to the phone while it's in bootloader mode. Yet entering recovery mode or getting a computer to connect to it via USB no longer seems possible.
I wonder if there's another way to issue fastboot commands without relying on the USB connection to a computer?

USB device will not power on in AOKP ROM

I just loaded up my LG V20 with the AOKP android 7.1, I plugged in my USB OTG ( SD micro card installed in this) and it will not even power on at all. I rebooted into TWRP, and it works just fine there, I can read, mount and unmount, no troubles. booted to system, but no power at all to the adapter plugged into the usb-c / charging port. My reader is a couple of years old, do you think it might just not be compatible with my new phone? Is there a setting I might be overlooking to enable this to work? Any ideas as to if it might be a hardware of software issue? Thanks.
