I think you just need to root stock. Otg works on stock. Idk about charging...

Any way to make it work?
I have that cable and it doesn't recognize the power input, even if no device connected to the otg port of the cable.

I assume you would need a custom kernel that supports this similar to the old Nexus 7.

It might be similar to the old nexus 7 and you can't charge while in otg mode. It was determined that it doesnt work from the sdcard hack in where once its in otg mode it disables the charging function so I'm assuming its going to be the same way sadly. Totally could be wrong but I wouldn't hold your breath

Will this application work on our device? I've searched and everything seems to say that there is no OTG in stock kernel. Some posts lead me to believe that certain roms have OTG enabled. If so, which ones?

[Q] Phone will only charge in recovery

Okay, I really searched for a solution before posting, so if I missed something, I apologize.
So I have a sprint gnex that just decided to stop charging today. So I obviously need to put it all back to stock! That'd be all well and good but as I just mentioned it won't recognize it's plugged into anything!
I've tried different cables, different batteries, none of it worked! Except for putting it into recovery. Twrp to be precise.
So how can I re lock a phone that isn't recognized!
I'm on a Mac and was using a stock rom
***update***
the plot thickens! So I have rolled it back to my most original backup thinking that would have fixed it.
I was right AND wrong!
It now charges off of my Mac, but it doesn't realize it is plugged into a computer at all (yes I have appropriate drivers). But I am talking about on the phone end too.
Really scrambling here
You can't. It's been gone over a couple times but the only way to re lock the device is to plug it into a pc.

No, the issue isn't me not having a program.
I can just use ADB over terminal.
The issue is my phone doesn't think it's plugged into a computer.

~sigh~
I guess my concern isn't well written.
The Phone doesn't know it's connected to a computer and vice-versa on ANY machine PERIOD.
All it does is charge now. So unless I can access ADB over WIFI (on CM9 I can I suppose), I feel screwed.

Nope.
But I managed to lock the bootloader, put a stock image on it, and kinda made twrp disappear. All without a computer or USB
So I solved the turn it in for warranty issue.
Thanks guys.

USB OTG

Hi Guys, I recently Purchased a USB OTG cable for my galaxt s4 Running Goosh v1.0 and Deviant Kernel.
My phone recognizes the cable when plugged in, but doesn't recognize my flash drive or anything else plugged to it, So my question is that do I need a Rom that supports it, a kernel or what. I have also downloaded usb otg helper from the play store and it says device not found..And also what format does the Flash Drive have to be in .??
I remember back with my sensation it was kernel related. It works with wicked v4 for sure. As far as the flash idk... All my flash drives have been recognized without me having to format.

Mines is a 32gb Flash Drive, I have a feeling the storage capacity is why it's not working.
Format it to FAT32, NTFS doesn't work with Stock Samsung.
Try StickMount

Are you rooted?
On my S4 with the VirginROM v2 it works. Tried it with a 16gb stick.
Most of these cables are sold have a quality that leaves a lot to be desired. When I ordered I got them for $3 each so i ordered 5 so I knew one atleast would work :laugh:

I currently Have USB OTG and that doesn't recognize it either.
Mind giving me a link to that NTFS Mount app, I have a feeling I have probably tried it as well, tried every OTG app available in the app store.

What storage Capacity though
I was able to mount my 8 GB USB stick with the stock rom and stock kernel. I used an old 5 in 1 MHL connection kit that I bought for my Galaxy Nexus. It has full size USB for OTG and it worked fine. Stick is formatted in FAT32.
Thanks you guys.. I was able to get it to work, it was just a bad flash drive

[Q] Using USB OTG with LS970

Is it possible to get the USB OTG cable to work on a ls970? I bought one and can't seem to get any devices to work. From what I understand, the phone is missing a 5v output and only a kernel can get OTG to work?
If this is the case, could someone please help me get in the right direction on getting this to work, or if its even worth it.
Rom: SuperNexus 2.0
Kernel: 3.4.0-gee_mako-dev
Regards,

You are absolutely correct. The Nexus4 doesn't have otg support built in, but they solved it by adding support to a custom kernel and using a y-cable to get over the 5v output issue. Sadly, it looks like no one has accomplished this yet for us. I'm not sure on the specifics but every thread where someone was trying it for our lgog looks abandoned without any reason. I'm curious about this as well and that's the info I have been able to find.

Could be bad - but it's at least a starting place. Modify it to somehow work for us since our chipsets are so similar......

[Q] < waiting for device > when rooting - no matter what

Well here I am. I'm brand new, so hello! I'm Tom.
I'm on Windows 8.2 trying to root my Samsung Galaxy Nexus.
I've seen a LOT of posts exactly like this, and I've tried absolutely everything I've seen suggested, yet I always end up getting stuck on < waiting for device > in the command prompt while trying to root, with nothing changing on my phone screen.
Every single time! I've used every method I've seen(including superboot), and resorted to manually navigating through Android SDK, only to reach
"< waiting for device >"
I've been at it for three hours after deciding that one of you (or more) skilled folks could definitely help me on my way to rooting.
Now, I'm not afraid to say that I'm new to executing this process. I've read up on it plenty, but putting it into practice has been troublesome for me, and if you could offer explicit instruction, it would be best.
Thank you kindly!
(Yes, it is in fastboot mode at the time of attempted rooting/fastbooting)
(Yes, USB Debugging through developer options is on)
Sounds like a driver issue but your phone is detected.. Weird but I think you should check your drivers.
Sent from my Galaxy Nexus using xda app-developers app
This may sound silly, but is it a driver issue on my phone, or on my computer?
And is there a guide on how I might go about fixing it?
(I took the time to re-install the USB Driver directly from Samsung website, if that's what you mean.
On your pc Just use device manager to see if there is any yellow exclamation mark by your device when its plugged in. If there is you need to update the driver manually. For that: all hail google lol

I updated the driver - directly from Google, as well. Alas, no luck. Do you have any other suggestions?

Use a different USB cable and try different ports.
I tried a different port, no luck there. It still attempts to start fastboot and stops at "< waiting for device >" - like before.
What does using a different USB cable change? I've yet to do it (but I will within two hours), and I don't see what difference it could make.
Thank you though. The help is very much appreciated.

A diffrent usb cable works because magic minions in your computer recognize the new usb cable and then go and install the right driver. No seriously I have no idea but it might work.

I have had a cord go bad before. Funny thing is that it would charge just fine. Trust me sometimes it can be the cord.
Also I have heard of the phones USB port having a couple of bent pins. This can result in the behavior you're experiencing. The phone will charge just fine but can't be recognised by the PC. If they are bent back into shape everything will be fine.
Wouldn't it prove that the USB Drivers were functioning properly from being able to sync files, use adb commands, etc?
I'm definitely going to try it - in about an hour - but I still question what makes it work.

So both of my USB Cables are fully functioning - and still waiting for device. Anything else you can recommend?

Have you looked at those pins inside the phone port yet?
You can notice if they are bent.

If all else fails try another PC.
I will try another PC.
In the meantime, I spoke to a friend, and we came to the conclusion that the version of Android SDK i'm using could be too new - the Galaxy Nexus was a product of 2011, after all.
Perhaps if I install an older version of SDK (however that's possible) I'll be able to root successfully? Just an idea.

I talked to a sales associate at my local mall, and he suggested I try http://www.cyanogenmod.org/ and it worked flawlessly. My phone is now unlocked, running CyanogenMod, and running Kitkat 4.4.
Thanks to everyone for the help! I hope all of your days are great.
