[MOD][KERNEL] Stock 4.2.1 + OTG - Nexus 10 Android Development

Hi all,
For the purists amongst you, like myself, I have attached a modified, repacked boot image that will mount (automatically) external storage devices to /storage/usbdisk and /storage.
You need to be rooted and unlocked.
Installation:
Backup your boot image with recovery of your choice
Reboot into bootloader
fastboot flash boot neostock421.img
reboot into android
rename vold.txt to vold.fstab (XDA wouldn't let me upload a vold.fstab)
copy and paste vold.fstab (attached) into /system/etc/
set permissions on vold.fstab to 755
reboot
plug in your drive and enjoy
Notes:
The storage device will not show up in settings/storage, that requires modification of the framework, I could do it (if there is a suitable apktool available) and package the lot as an update.zip but for the time being I won't.
Observations:
I have observed that in Root explorer, the device is mounted read-only initially (you can simply remount read-write), but if I open /storage/usbdisk in Estrongs and return to Root Explorer, it's now read-write. Either way, you should no trouble getting read-write.
Warnings:
Do the above at your own risk, I take no responsibility, bla bla, etc etc.

Thanks for your stuff
Added in the Index for N10

Hello! Thank you! I can flash this on stock ROM? OTG will work?

Yep,
That's the Idea Enjoy.

Does it support ext3/4 file systems, or only FAT?

This is not good!
ITS GREAT!
Thank you!!

It just auto mounts existing supported file systems, nothing more, nothing less.
I haven't tested it with anything other than a fat file system cause that's all I have on my pen drives.
Unfortunately the N10 doesn't appear to source enough power to power my 2.5" hdd, shame cause my XOOM used to power it just fine.

I am using an external WD My Book Essential with external power supply. Is it suppposed to have a notification after it's plugged in? Cause it doesn't happen and it doesn't appear in Settings -> Storage.

Nope, no notification, and nothing in Settings->Storage (like I said in OP).
Just open your file browser and it's mounted and visible in 3 places;
/mnt/usbdisk
/storage/usbdisk
/usbdisk

Had to wait for some time, I guess it needed it to index the files or whatever, finally it's working.
Thanks for your awesome work, I really missed only the USB OTG storage support from the stock jop40d

What is your HD formatted in, FAT32 or NFTS?

How does this work with TWRP? Meaning, if a flash drive is selected as the destination, on a reboot of TWRP, is the setting retained?

@alias_neo, hit me up on PM... I'd like to work with you to get this to a better state... aka, NTFS & settings storage support... I'm not running stock right now, so I need someone to send me some files and test it!!

How to Copy/Transfer files > 4GB to HOX

hi all
any1 know of a method or programs to copy/transfer files > 4GB to HOX?
Just mount as Removable Device, right click and Paste. I copied a 12gb HD movie to my HOX last night.

I have done that.. and then it stops to tell me cant copy/transfer files > 4GB because FAT32 does not allow it (Partition type limitation)
I even tried FTP'ing the file to the device and it stopped at 4GB exactly
Have you formatted your card differently?
are you using windows to transfer/copy the files? (I am)
do you use the standard windows copy/transfer method? (I am Using TerraCopy)
just plug the usb to pc and format the sd card as NTFS and you can remove the limitations of 4GB

Won't that affect how apps are installed as well? AFAIK most devs optimise their apps for FAT32, as it's the default format of the storage.

have you formatted you SD to NTFS?
as I have read on another Forum post that once they formatted the Card and rebooted.. the card reformatted to FAT32
@dr9722 could you please state all your system specs that has allowed you to transfer the files
including the model of your HOX and the ROM maybe this affects it as well (dont know why it should??)

personally, i split the files with this method:
www.logichaos.com/joomla/guides/35/60-how-to-split-mkv-to-multiple-mkv-files.html
website isn't loading at the moment, maybe server is down or something
(google cached text only version works though: http://webcache.googleusercontent.c...tiple-mkv-files.html&hl=en&prmd=imvns&strip=1 )
if it still isn't working later theres loads of other pages that show ways to do it just search google for how to split mkv files
bit of a pain, but i normally watch tv episodes rather than movies so they're normally small enough even when in hd

It'd have to be formatted as exFAT or something. I don't know if it's doable, but that's the only way I can think of. Or possibly as ext4 and do file transfer via MTP.

Thanks man I know about that method but thanks for the info great help for those that wanna copy movies to their phone
my problem lies in an actual file Copy ie. DVD image
yes I can zip it and split the files into varying sizes but then it defeats the purpose as I would like to move the file as is (time saving)

if i'm honest, i don't think it's possible without a rom mod - maybe ask a rom developer if it's possible.
you would need to modify a lot of stuff so it all works together properly, and that's if its ntfs.
exfat would no doubt be easier on the android side to implement, but then you'd need an app on windows side to be able to read that (win7 might actually include exfat support actually...)
still it's not something possible by means of just an app etc i don't think.

dont think this is specific mkv splitting so you wouldn't be able to watch the split mkv, you'd need to go onto a pc and merge the files before you could watch it, which would then leave you with a file that is once again too big to fit onto the phone :silly:

[CM9] Can we enable MTP?

Like the title, I'm asking if there is a way to use MTP in CM9 for our device, like this.
Arco says that the MTP is a problem in every Samsung device with a CM9 but for GS2 for example is fixed.
No one knows how to make it working?
Thanks in advantage, and i'm sorry if I'm in wrong section or if isn't a considerable problem
i got a bug on that.. i think it is also affected by USB tethering..
My question is: Do you really *need* MTP?
If what you're after is a simple way to transfer files from/to the SDcard, I recommend using AirDroid instead.

seems when i press on Mount sd card nothing happens..

you need to use adb.
mounting the sdcard does nothing on the nexus as there is no mass storage

You really need to READ. Use a translator if you can't.
from the thread Zepius linked you:
What is the Android SDK and do I need it?
SDK stands for "software development kit. Do you need it? If you are developing, then yes (but then you probably would be reading this thread now would you... ). If you are not developing, then no, you do NOT need to install it. It is just a waste of space. The only files you need (to interface with your PC) that comes from the SDK are the fastboot and adb files, and they can be found here for Windows, Linux, and MacOS.

you won't scew anything up doing that. and the only way to get it working is by figuring out what the heck the mount points are and applying them. It only works for external sd card btw. And i would run the commands myself but i don't have the note 3. I kinda want it but it seems too big.

I moddified my S4 UMS Widget. if it doesn't work, i am going to need more information. Let me know if it works or not.
It requires root of course. And if it doesnt work keep tapping it till you get back to MTP mode and go under USB setting in settings app and set that to MTP mode and you should be back to normal again. Really wish i had this to help you guys with mods and what not. but i'll do my best.
I tried the UMS Widget you posted. When I connect my phone to my computer with UMS mode from the widget the phone shows up as a CD-ROM drive, not a removable storage. If I try to click on the CD-ROM drive it asks me to insert a disc. Seems very strange to me.

/sys/devices/virtual/android_usb/\
Give me the output of all the contents of android_usb directory.
you can type ls /sys/devices/virtual/android_usb > /sdcard/Stuff_in_android_usb.txt
to output it to a text file on your SD card.
The only thing in /sys/devices/virtual/android_usb is another directory called android0. I've attached the contents of /sys/devices/virtual/android_usb/android0.

Accelerometer is a sensor that defines a devices's position, so it gives you ability to use such functions as screen auto-rotation. And the bug is that sometimes this sensor stops working until the next reboot.
1-After format the SD with cm13, then how to back to normal SD?
2-Is right that if we use sd like part of system we can't use real system memory?
3-After formatting SD (with cm13) for using it like part of system, if we try to put it in PC and then back in the phone, it's real that the SD automatically delete all file inside it because was encrypted?
4-Can we store file like music, photo, video... on SD or it's only for app?
5-If for example i break my phone and put SD in an other phone what happen?
I know that are a lot of question but i hope someone can answer

1. Settings > Storage & USB > sdcard > menu > Format as portable
2. No, sdcard space magically adds to real internal
3. Of course no.
4. From phone: yes, photos goes there
From PC: unknown, because MTP broken now. But probably yes.
5. Data will be unaccessable because partition encrypted.
And formatted in unusual way - Windows anyway can't deal with it.
Card supposed to work only with ROM where was adopted (key stored)
UPD: it somehow works in other phone
You can format back it into FAT32 via Explorer or some partition manager.
Also seems this feature still semi-broken: large games won't install.
Maybe PecanCM can fix it.

There are often problems with Android on Windows that are absent on Linux. I had irritating issues with UMS mode in TWRP when I was using Windows (more strange is that it worked earlier and then suddenly my PC went insane when connecting USB in TWRP with storage mode enabled), but on Linux it works like a charm. And it is not the only example of problems in Android-Windows "relationship".
Guys I flashed the rom and it booted as usual and i went to next page of the setup guide i.e. add wifi in that i tried connecting to my wifi but while entering the password it shows unfortunately, aosp keyboard has stopped after i removed my wifi password and connected then it goes again to the first page of selecting country and i repeatedly pressed the yellow icon to proceed to the next page but its stucked on that page plz help me guys and do i need to do anything else?

Oh, there are a bunch! Wondering how it'll fare with the Android File Transfer on Mac. �� At least, ADB works, right? I need to update a few of my apps to support Marshmallow since they removed the Apache HTTP client (Google, must you really make things difficult? I spent an hour yesterday writing 75 lines of code just to add dividers between RecyclerView items... SMH). I'll most probably be shifting back to Lollipop AOSP by tonight. Anyway, if MTP works, I'll update you guys...
EDIT: So, no. Unfortunately, doesn't work on OS X as well. I didn't really expect it to, but then I was hoping that since it was UNIX, it would.
EDIT 2: So, it works with OS X as well! I hadn't selected the USB to transfer files previously.
