[Q] USBOTG for Galaxy Y GT-S5360 - Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl

This is my first thread/post in the forum, so I am not quite sure if this is the right place for this question. I recently happened to see a schematic diagram of the GT-S5360. I noticed that the main chipset includes support for USBOTG HS(480 Mbps).
http://forum.xda-developers.com/showthread.php?t=1489767
If this is indeed true, is there any way we can enable this feature in the GT-S5360? I mean, is there a custom ROM/Kernel which enables this feature?
Apologies if I have posted this in the wrong section.

If you have usb otg cable then try kuro and merruk kernel....
And search before posting

Hi, please look in the dev section. We already have 2-3 kernels which enable us to use this feature, if i'm not wrong.

that is a block diagram not schematic

Thanks for the response Alkesh, I will try those. I had infact searched for something similar in the forum but could not come up with any names - maybe I did something wrong. I found this though: http://forum.xda-developers.com/showthread.php?t=1493325

my kernel didn't support it
my kernel is based on samsung's sourcode. on other hand, our "beloved" samsung have messed up the source code. thus, make the OTG stuff on the kernel didn't work.

Thanks for clarifying Kurotsugi. So is there any kernel which supports this feature currently? I searched the development forums - seems Merruk also doesnt support this feature currently, Maroc-OS is working on it as I understand from http://forum.xda-developers.com/showthread.php?t=1550065

if you have the cable you can try that.

ask samsung

works now
Hi guys.
Sorry for necroposting.
Also this post should probably go to development section, but I don't have access to post there (yet?).
First of all, BCM21553 seems to lack ID pin. ID pin from USB connector goes straight to PMU chip instead.
It is used to detect the type of the charger as far as I can tell.
It's not a big deal to extend PMU isr's to support OTG cable as a different type of charger (yes, external +5v source is required).
The real trick (for me) was to find a way to force DWC core into Host mode. Looks like Synopsis is no longer sharing datasheets with public.
Luckily Broadcom is not the only company which uses the same USB IP.
It looks like DWC driver was designed for an older kernel version.
It was partly ported by Samsung, but only as much as required to support the device mode.
It's still very flaky and fragile. For instance, it you try to cat /sys/devices/lm-2/mode, it will panic the stock kernel.
All HC code is non-functional and does not even build out of the box.
It took me almost a week to fix all the bugs and to be able to build standalone dwc_otg.ko with working HC code.
At the moment I managed to successfully mount a memory stick on my phone. Device mode is not there yet, but I don't really need it:
I'm building a telemetry project and I need the cheapest solution.
If anypony is still interested in HC on SGY, please reply and I will follow up with more details.

thats pretty awesome news.....this should be moved to development section......

Currently I'm working on PMU driver to allow the phone to charge while connected via Y-cable.
Once ready I'll post some binaries and patches against stock kernel sources so you will be able to try it out, or take over if you would like to.
After that I could probably try to restore gadget functionality as loadable module and probably add something to switch device/host mode automatically based on cable type.
But personally I don't need gadget functionality at all, so I'm not sure when I will be able to find enough spare time to do this.
PS.
Please don't move it to development section just yet - I won't be able to post there (need 10 posts or something like that).

Here we go, as promised.
I've decided to test whether SGY is powerful enough to play movies from external USB HDD drive with truecrypted ext4 fs.
It turns out to be good enough.

Attachment contains kernel update which you can flash using recovery mode.
Basically, it is an ordinary Samsung kernel without any USB code and with some minor hw-related tweaks.
modules.tar.bz2 contains all modules from snippet above plus HID and FTDI support.
It's huge because of ext4.ko. You probably won't need it.
dwc_otg.ko is USB driver itself. At the moment it has host-only functionality.
It means - it is a very bad idea to connect your phone to PC with this module loaded. Be warned.
Also, I'm using Y-cabe with 30k resistor between D+ and D-. This way MUIC thinks that phone is plugged into 1A charger.
At the same time, D+/D- is routed USB PHY. This hack is statically linked into the kernel.
So - don't try to charge your phone with this kernel with chargers with D+/D- shortened.
Oh, yeah. ID pin connection is irrelevant at the moment, so you can hack any micro-usb cable in the middle - no complex soldering required.
Disclaimer: You may brick your phone. Do it on your own risk. This post is developer-oriented.
If you do not fully understand what's written above - better don't do it at all.

Dude what you are doing is great but the problem is its too much difficult for average member to understand what all this means....you should give a better discription about what you have done with the kernel and what is the advantage of that and how it will work.....uploading kernels like this could lead to someone bricking their phone....
According to me you should team up with someone and make a thread in dev section.....

Yes, I know, but there is nothing user-friendly to show yet.
There is not much profit for an avg phone user until automatic switching between host and device mode is added.
After this feature is implemented in usb driver, it could be incorporated into someones custom kernel distribution and OTG will just work out of the box.
At the moment it is just an ongoing development, which I would like to share with other developers, because I do not think I have enough motivation to finish everything by myself.

There is a thread about OTG on SGY already in development section, but I can't even bump it - no rights to post there.
Someone could probably post a link to this thread there, I suppose.

btw, I think you need 10 posts in order to start a thread or post on development section.
anyways, keep up the good work!!!

what need to doing ?
flash your kernel
for what is modules and dmsetup ?
I can't understand ?

Attachment contains kernel update which you can flash using recovery mode.
Basically, it is an ordinary Samsung kernel without any USB code and with some minor hw-related tweaks.
modules.tar.bz2 contains all modules from snippet above plus HID and FTDI support.
It's huge because of ext4.ko. You probably won't need it.
dwc_otg.ko is USB driver itself. At the moment it has host-only functionality.
It means - it is a very bad idea to connect your phone to PC with this module loaded. Be warned.
Also, I'm using Y-cabe with 30k resistor between D+ and D-. This way MUIC thinks that phone is plugged into 1A charger.
At the same time, D+/D- is routed USB PHY. This hack is statically linked into the kernel.
So - don't try to charge your phone with this kernel with chargers with D+/D- shortened.
Oh, yeah. ID pin connection is irrelevant at the moment, so you can hack any micro-usb cable in the middle - no complex soldering required.
Disclaimer: You may brick your phone. Do it on your own risk. This post is developer-oriented.
If you do not fully understand what's written above - better don't do it at all.

A Biggg Thanks to you Master....
I am the one who tried for the same target before... But not yet successed..
I am very much curious to see the source or the patch for this.
I hope you will move your code to github or somethig...
Again .. You have Done a Great Job..

Sorry for reviving old post first of all guys, I'm a Galaxy Ace-I user (cooperve, not cooper) and I've found out that our phone in particular, just like the SGY has a BCM21552 (physically that's what the chip reads not 21553 lol), which also supports OTG as I've stated in this thread, I really think it'd be interesting if S5830i and SGY developers could join forces to make this go through

Whats the status of last development of OTG support?

/system writable with unionfs

Hi,
I've followed the instructions on how to build froyo on Ubuntu 10.04 32Bit,
I had to disable gdb in /buildroot/local/g8_arm/g8_arm.config
or shot make -i world
make menuconfig breaks everything
....so edit configs by hand.....
then it builds fine.....
thanks to his patch:
www android-hilfe de /android-os-entwicklung-customize/4801-kernel-module-kompilieren-erster-versuch.html
it runs (else unionfs complains about missing symbols..)
Code:
adb push unionfs.ko /data/local/tmp
adb push ntfs.ko /data/local/tmp
I've created a second 2GB ext3 partition on my sdhc class6
Code:
insmod /data/local/tmp/unionfs.ko
mount /dev/block/vold/179:18 /data/newroot
mount -t unionfs -o dirs="/data/newroot/rootfs=rw:/system=ro" unionfs /system
and now i've things like a writeble host file .....
it runs since yesterday here - and is fine.

For morons like me what does that mean....root access??
Sorry if that is a dumb question
@mothy
so far, temporary root with writable /system directory
So just to be clear. Do you replace the kernel at all?
And do you have to mount the sd partition every time you boot up?
It's for the original Archos Kernel 2.6.29-omap1
Code:
# lsmod
ntfs 213028 0 - Live 0xbf276000
unionfs 74364 1 - Live 0xbf211000
this means you have to
temproot+"re"mount
the writable places, maybe soft-reboot (i use LCDDensity, it's soft-rebooting) and all your're changes are magicly there
instead of using sd, you can just create /data/newroot and let the things go there
Code:
# df -h
/dev/block/mmcblk0p4 299.4M 205.1M 78.9M 72% /data
i don't see any new rom's soon, unless we get a new bootloader, Archos uses mmcblk0 (an SD-Card device) and not mtd, so i think we can forget all that fastboot, flash_unlock mtd stuff.
this is very annoying, maybe i'm wrong,
but it looks like they don't want us to reflash the device :-(
unionfs usually need a own kernel, but the "ugly patches" make it run with the archos gen8 kernel
So i use temproot, gscript, LCDDensity after each reboot - and have all my settings back, apps like adsfree runs...
jens
forgive my lack of knowledge but you keep mentioning ntfs in the code fragments but you havent actually said that this is giving you ntfs support. does your kernal changes allow for reading ntfs volumes?
yes, i hope so, but i havn't tested it until now, minimum is that you can mount ntfs volumes by hand - but maybe it's automounting....
i want test a HD movie from sd, but mine doesnt fit in 4Gig (fat)

USB Host mode on Defy

Has anyone tried Defy's USB Host mode?
Would like to attach USB devices onto Defy:
- USB keyboard / mouse
- USB disk drives
- Other types of USB 3G modems (like CDMA1x/EVDO)
- Arduino IO board
...
I haven't bought Defy yet, but want to do some pre-research before the purchase.
Could someone do me a favor to post the outputs of "dmesg" on Defy?
(Run dmesg command under the Linux console).
I expect to see something like:
Code:
...
OMAP3630 ES1.1
...
twl4030_usb twl4030_usb: Initialized TWL4030 USB module
usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub

musb_hdrc: version 6.0, musb-dma, otg (peripheral+host), debug=0
musb_hdrc: USB OTG mode controller at fa0ab000 using DMA, IRQ 92
...
I got above dmesg by Web searching for an OMAP3630 test board, not a Defy.
Just want to make sure Defy is equipped with USB OTG controller.

Understood the bootloader is locked by Moto, and a kernel must be signed.
Instead of replacing kernel itself, can we just load new driver modules (*.ko via insmod command)?
Does Moto also prevent from loading customized driver modules?
Can someone help to get the outputs of "cat /proc/driver/musb_hdrc" ?
Something like:
Code:
#cat /proc/driver/musb_hdrc

One correction to my previous command line for current USB mode:

How about to use:
"echo b_host > /sys/devices/platform/musb_hdrc/mode"
to enable the Host mode again?
May run command "modinfo musb_hdrc" to get actual parameters we can use to enable the Host mode.
Something like "modprobe musb_hdrc mode_default=1".
$ cat /sys/devices/platform/musb_hdrc/mode

I have usb y cables so i can power the hosts with an external usb charger.
Any news on this?
It will be nice to see an USB host patch/mod on Defy
hi
I've seen that some phones will enable host mode if you boot them with the data pins shorted, done with a "dongle". anyone tried this on the defy? I'll make one and try it if no one has.

hmm.. is that safe? I dont want to burn my usb port..
I doubt it will damage anything. they won't be able to source enough current.
I've checked and the omap3610 supports usb otg. I will try to test this weekend.

Scratch that, it is not the data pins, you connect the "extra" pin (pin 4) to ground.

maybe we need another kernel,i think

Flashed a kernel? Now your xoom is on fire...

I think the most common problem we are seeing is people not clearing the old files. Before you download a new kernel and extract it, delete the old files from your SDK directory on your computer. Everyone that has had a problem so far, either screwed up a step or flashed a combo of new files and old files (ie the wifi not working after). So again BEFORE you extract the new kernel, REMOVE all old kernel files from the SDK directory on your computer.
List of files:
boot.img
/system/lib/modules/bcm4329.ko
/system/lib/modules/tun.ko
/system/lib/modules/scsi_wait_scan.ko
/system/lib/modules/cifs.ko
/system/etc/vold.fstab
You may ask why i didn't post this in the development forum, cause i'm not developing anything.
upgrading from Tiaman 1.1.6 to 1.3.1 just overwrites them ... you mean changing kernels completely right?

No i mean the files on your computer, not the xoom. People are extracting the files into the SDK directory. Then leaving them there to mix with the new files. The xoom will overwrite what it needs to.

This is why I always copy my files into a temp directory as shown in this post
Or just use a different folder for each version, and cd to the directory before you flash.
Also, you can do adb push system /system, and it'll put them in the right folders if you have it mirrored in your PC's folders.
Mine doesn't power up after following the procedure, it stays in the Motorola Dual Core logo..
I guess no XOOM for me until tomorrow

Connecting Android to a serial device using USB-Serial Converter

I am attempting to connect to a serial device from a Android tablet, via
USB-Serial Converter. In order to interface with this particular serial
device, a linux library must be used as an interface.
This library takes an integer as an argument, and tries to connect to the
device at the following location : /dev/ttySx, where x is the arguement. If
2 is provided to the library, it will look for the device at /dev/ttyS2.
Very simple.
When I connect the device to Ubuntu, there's is one simple extra step for
this device to work with the USB-Serial convert. The converter is exposed
at the location /dev/ttyUSB1. I just need to create a simple soft-link with
the serial port pattern (etc "ln -s /dev/ttyUSV1 /dev/ttyS99"). It works
perfectly.
Now the problem arises for Android. The converter is seen at
/dev/bus/usb/01/01. I never seen this convention in other project. The
question is how can I direct the I/O from /dev/ttySX to /dev/bus/usb/01/01

Which android device are you using and with which kernel and android build? In my case I am using kernel 3.0.+ with CM9 on a Kindle Fire and I do see the /dev/ttyUSBx getting created along with the /dev/bus/01/01. It has been a month since I tried it but I was able to see the problem you see and here is what I remember. When you plug the serial convertor both /dev get created but since the Android USB support only uses /dev/bus/usb/01/01, the kernel in order to save power "unmounts" the unused /dev/ttyUSBx after a certain time period. You can try using dmesg to see if that is happening in your case also. There is a kernel build flag that tells the kernel not to "unmount" it but I dont remember it off-hand. Best would be to use the Android USB support to talk to your device instead of the linux library if you can.
--------Update after testing it out again and checking dmesg etc---------------------------
When I plug the FTDI cable this is what shows up in dmesg:
<6>usb 1-1: new full speed USB device number 8 using musb-hdrc
<3>usb 1-1: device v0403 p6001 is not supported
<6>ftdi_sio 1-1:1.0: FTDI USB Serial Device converter detected

<6>usb 1-1: Setting MaxPacketSize 64
<6>usb 1-1: FTDI USB Serial Device converter now attached to ttyUSB0
At this point if I check the filesystem I see both /dev/ttyUSB0 and /dev/bus/usb/001/0xx [ xx being the current device number ]
I can work with /dev/ttyUSB0 and all is well. Now as soon as I invoke any app that uses Android USB Host Mode API to connect
to USB (for enumeration, connection or whatever) the /dev/ttyUSB0 gets disconnected with following message from dmesg:
<6>ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
<6>ftdi_sio 1-1:1.0: device disconnected
At this point /dev/bus/usb/001/0xx is still alive and if I enumerate the USB devices using android API I see the same as the adaptor
name. So looks like till the Android USB API takes over the FTDI is available as /dev/ttyUSB0 but not afterwards.
------------------------Update ends--------------------------------
(a) If you see a /dev/ttyUSB1 device node created, then you can try the following in an Android terminal:
Code:
stty -F /dev/ttyUSB1 raw
cat /dev/ttyUSB1
If this shows data from your device, then you can use directly the device node to read()/write(), POSIX-style, without needing any library.
(b) If you cannot see a /dev/ttyUSB1 in your Android device, this means that you need to load the ftdi_sio kernel module (check android.serverbox.ch/?p=285 for instructions).
Let me link that for you:
"How to enable FTDI Support for your USB Host featuring Honeycomb Tablet (including sample native application)"
Also have a look at FTDI's Android Paper:
"White Paper: Connecting Peripherals to an Android Platform"
and this relevant blog, from this XDA thread.

Which android device are you using and with which kernel and android build? In my case I am using kernel 3.0.+ with CM9 on a Kindle Fire and I do see the /dev/ttyUSBx getting created along with the /dev/bus/01/01. It has been a month since I tried it but I was able to see the problem you see and here is what I remember. When you plug the serial convertor both /dev get created but since the Android USB support only uses /dev/bus/usb/01/01, the kernel in order to save power "unmounts" the unused /dev/ttyUSBx after a certain time period. You can try using dmesg to see if that is happening in your case also. There is a kernel build flag that tells the kernel not to "unmount" it but I dont remember it off-hand. Best would be to use the Android USB support to talk to your device instead of the linux library if you can.
--------Update after testing it out again and checking dmesg etc---------------------------
When I plug the FTDI cable this is what shows up in dmesg:
<6>usb 1-1: new full speed USB device number 8 using musb-hdrc
<3>usb 1-1: device v0403 p6001 is not supported
<6>ftdi_sio 1-1:1.0: FTDI USB Serial Device converter detected
<6>usb 1-1: Detected FT232RL
<6>usb 1-1: Number of endpoints 2
<6>usb 1-1: Endpoint 1 MaxPacketSize 64
<6>usb 1-1: Endpoint 2 MaxPacketSize 64
<6>usb 1-1: Setting MaxPacketSize 64
<6>usb 1-1: FTDI USB Serial Device converter now attached to ttyUSB0
At this point if I check the filesystem I see both /dev/ttyUSB0 and /dev/bus/usb/001/0xx [ xx being the current device number ]
I can work with /dev/ttyUSB0 and all is well. Now as soon as I invoke any app that uses Android USB Host Mode API to connect
to USB (for enumeration, connection or whatever) the /dev/ttyUSB0 gets disconnected with following message from dmesg:
<6>ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0

are you using ftdi's code to modify it?
change /system/etc/permissions
this is from a question on stackoverflow titled "Android USB host and hidden devices" (sorry, i can't add external URLs yet). it worked like a charm on a micromax A120 canvas 2 phone (kitkat 4.4.2). now i can control my Arduino! i used busybox tools to do all the command line work (otherwise chmod wouldn't work). my steps (perhaps some were not required):
(0) install PDAnet drivers on my Windows 8 computer.
(1) root the phone using Vroot (now called iRoot). Very simple, only catch is that the su grant/deny page is partly in chinese, no big deal.
(2) install busybox and jackpal's Android-Terminal-Emulator available on github and the google play store (free).
(3) open a terminal window and become the superuser:
# su
(4) the file system may be read-only, so you might have to remount it:
# mount -o rw,remount -t yaffs2 /
or
# mount -o rw,remount -t rootfs /
or
# mount -o rw,remount -t rootfs rootfs /system
(5) make default.prop read/write:
chmod 666 /default.prop
(6) edit /default.prop, make the following changes:
ro.secure=0
ro.debuggable=1
persist.service.adb.enable=1
... And this is the real meat of it:
(7) To enable USB host API support you should add a file named
android.hardware.usb.host.xml and containing the following lines:
<permissions>
<feature name="android.hardware.usb.host"/>
</permissions>
into folder
/system/etc/permissions
in that folder find file named
handheld_core_hardware.xml or tablet_core_hardware.xml
and add
<feature name="android.hardware.usb.host" />
into <permissions> section.
(8) Reboot your device. Usb host api should work.

Is my Nexus 7 dead?

Okay, I have fastboot and ADB, the only way to get into recovery is through wugs toolkit. I have pushed a ROM to my phone but is says FAILED when I try to flash.

Any help is much appreciated.
Now this is my 4 year olds tablet and we woke up the other morning and it just wouldnt boot anymore. I did unlock it just for fun when we got it a couple months ago but I dont know why it would just not boot into the OS after two months.
In the situation you are in, you should NEVER use fastboot to attempt overflashing of the bootloader. All else, OK.
Try soft-booting (not flashing) a more recent recovery, e.g. TWRP 2.3.x.x or 2.4.x.x
pull it down to your computer & verify it's MD5 sig, then
fastboot boot recovery-image-name.img
If that works, via "adb shell" (once the recovery starts, ADB should work), see if you can do a
# mount /system
# mount /data
if these succeed, that means that each filesystem is OK. (Already mounted counts as a success) If it doesn't you will have to use the mke*fs tools located in the /system/bin or /sbin folder of the TWRP boot to re-initialize the /system, /data partitions as necessary.
My guess though is that if the device failed before all this happened, things might not be fixable.
If you can't even soft-boot a recovery - let us know what error message occurs.

well, if you are using the touch version of TWRP the "format data" command rebuilds the filesystem (after nuking it first) with mke2fs.
The command line for mke*fs can have lots of arguments, and off the top of my head I don't know which device plumbed into the kernel is the correct device.
Gimme a minute, I just did a factory reset on my tablet.
But yeah, if you are doing stuff manually from the command line with adb, you will be using the executables in the recovery's /sbin or /system/bin or /system/sbin (e.g. the mke2fs command).
Hang on, gotta check something.

did you try re-creating those filesystems?
probably you should add /cache in there for good measure
mke2fs -T ext4 -m 0 /dev/block/mmcblk0p9
mke2fs -T ext4 -m 0 /dev/block/mmcblk0p3
mke2fs -T ext4 -m 0 /dev/block/mmcblk0p4
It is possible that when you are in fastboot mode (bootloader), the bootloader does not rely on having intact filesystems and performs a wipe and re-creation of each filesystem before it unpacks those (sparse) ext4 image files onto the targets.
But what I am suggesting above will give you more visibility into what is going on than using fastboot.
Given that you don't know where the trouble is, as I said before you should not be doing ANYTHING at this time which overflashes the bootloader - including installing full factory images.

It looks right for the stock kernel, but stuff gets plumbed into the device tree differently depending on kernel.
Which recovery are you using?
you could try the "by name" devices:
mke2fs -T ext4 -m 0 /dev/block/platform/sdhci-tegra.3/by-name/UDA
mke2fs -T ext4 -m 0 /dev/block/platform/sdhci-tegra.3/by-name/APP
mke2fs -T ext4 -m 0 /dev/block/platform/sdhci-tegra.3/by-name/CAC
(UDA -> /data, APP -> /system, CAC -> /cache)
BTW - if you haven't figured it out by now - you get "out of" the remote shell by typing the command "exit". You'll see the prompt change back to the Windows command prompt "C:\blahblahblah>"
Hmmm - those "by-name" entries are symlinks back to the same device names I gave you originally. Well, on the stock kernel anyway.
what does the command "ls -ld /dev/block/*" get you (on the adb shell) ?
---------- Post added at 08:12 PM ---------- Previous post was at 08:07 PM ----------
Send me a link to the place you downloaded your recovery image from, I can soft boot it and take a look.
either that or do a "cat /proc/partitions" and let me know what the output is.

Skyler - we may well have stumbled onto the problem. I booted a couple of different recoveries, and they mostly plumb devices into the same device nodes in /dev/block.
What that suggests is that your partition table got mangled.
If it turns out that this is the case, your question "Is my Nexus 7 dead"? can probably be answered in the affirmative - until someone clever reverse-engineers the Nexus 7's APX mode.
There is a way that you can check this - with the "dmesg" output from your soft-booted recovery.
From the windows prompt, do this:
- soft boot the recovery (so it has been fairly recently booted), and once the ADB link comes up, do this:
C:\ugh> adb shell dmesg > dmesg_out.txt
this (the file "dmesg_out.txt") will have the kernel boot log in it. In an orderly boot, you would see something like this:
Code:
<6>[ 3.629591] [mmc]:mmc_read_ext_csd:285 ext_csd.sectors 0x3b78000 prod_name

If you are missing a bunch of partitions, you have a problem with the eMMC Flash memory chip that is not currently correctable with tools in the wild.
Is that what you see - errors in the dmesg log, or a lack of partitions in /proc/partitions?

Skyler - we may well have stumbled onto the problem. I booted a couple of different recoveries, and they mostly plumb devices into the same device nodes in /dev/block.
What that suggests is that your partition table got mangled.
If it turns out that this is the case, your question "Is my Nexus 7 dead"? can probably be answered in the affirmative - until someone clever reverse-engineers the Nexus 7's APX mode.
There is a way that you can check this - with the "dmesg" output from your soft-booted recovery.
From the windows prompt, do this:
- soft boot the recovery (so it has been fairly recently booted), and once the ADB link comes up, do this:
C:\ugh> adb shell dmesg > dmesg_out.txt
this (the file "dmesg_out.txt") will have the kernel boot log in it. In an orderly boot, you would see something like this:
Code:

note that it detects 9 partitions
and further, the command
C:\ugh> adb shell cat /proc/partitions
should display something like this:
Code:

Well, that explains that. Some bootloaders (usually S-OFF engineering bootloaders, not public release bootloaders) allow re-partitioning if the device gets completely stuffed up, but generally the public release bootloaders do not - which explains why flashing the factory roms from fastboot mode was failing - it too needs to read the partition table(s).
The Tegra 3 has this mode called "APX" which is similar to the "download mode" on Samsung phones where the PC application "Kies" can be used for manipulating Samsung phones at a very low level, including things like repartitioning the basic flash filesystems. It's what makes those Galaxy phones nearly impossible to brick, short of hardware failure.
Until we have tools for working in APX mode though, situations like yours are a dead end even for rooters.
RMA time? I don't think it was anything you or the 4-year old did by the way - I would engage with Asus/Google with a completely clear conscience.

I called and I am doing an RMA, Ill be shipping it off tomorrow or the next day. I will post back if they actually send me another one. Google was amazing by the way, a real pleasure to deal with. I appreciate all the time you and bradman put in tonight to help me figure this out. I REALLY REALLY REALLY appreciate your time and efforts! This has by far been the best experience I have had on any forum! You guys are awesome!
Well they received my device. Waiting to see if I get charged or get a new one.

You deserve a lot more 'thanks' in your posts for doing so much to help the OP.
