APX Mode after Nexus 9 was run-over by a car - Nexus 9 Q&A, Help & Troubleshooting

Hi,
Yesterday my Nexus 9 was run-over by a car while it was in my backpack.
It still looks perfectly fine and was just slightly bent on the top where the mainboard sits.
The only problem is that it does not turn on
When I connect it to my laptop I get the following message:
Code:
[ 1951.490340] usb 1-4: new high-speed USB device number 19 using xhci_hcd
[ 1951.674845] usb 1-4: New USB device found, idVendor=0955, idProduct=7f13
[ 1951.674848] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 1951.674850] usb 1-4: Product: APX
[ 1951.674852] usb 1-4: Manufacturer: NVIDIA Corp.
I searched a bit and it seems that it is currently not known how to enter the APX mode.
Does anybody have experience with nvflash and would like to help me to diagnose the tablet?
(I suspect a broken solder joint on the EMMC chip)

@donothingloop,
If you are feeling adventuresome, follow this guide to disassemble it and look for the issue > https://www.ifixit.com/Teardown/Nexus+9+Teardown/31425

Hi,
Have already disassembled it.
Found no defect which is visible to the eye.

[Q] CDC ACM device

Hello everybody,
please my question is very simple.
Can I use CDC device (USB-SPI converter by Microchip) with GT7500?
The device uses CDC ACM drviers. When I plug in to my computer I see ttyACM0 is created in /dev/ folder.
If I connect device to GT7500 throw USB Adapter dmesg inform me about Device not supported (dmesg short report in bellow). But if I look to .config i see is CDC ACM driver is inculded.
If plug device to my second tabled WM8650 everything is OK. /dev/ttyACM0 is created and accessed from app.
Thanks for any answer.
Tulak
Sorry my english.

Hi,
I also have similar problem of a cdc-acm device working on one tablet and not on the other.
On the tablet on which it doesnt work, the ROM doesnt come with the cdc-acm.ko so it was "insmod" ed
Any help on this? Anyone?
I have the same problem with Samsung devices, any one?

Anyone using fastboot with linux?

[Q] Broken Screen and ADB says offline device

Hi,
the display of my galaxy s2 is dead and now I'm trying to recover all my data. If I connect the phone via usb to my pc Windows recognizes it as an usb media but I gain no access. Under Linux it gives me the following error
Code:
Unable to mount Android
Unable to open MTP device '[usb:002,003]'
Dmesg shows the following output
Code:

lsusb also shows the galaxy s2:

but the problem is that adb devices -l says it's still offline, so I can't connect..
Code:
List of devices attached
0019adcd587f8e offline usb:2-1.2
Maybe the problem is that my device boots until the PIN screen and I can't unlock it .. but I think it could be even a hardware issue.. Also I have a custom rom + custom kernel installed (it's called ressurection remix)
So is there a chance to connect my device?
EDIT: now, after a few times of trying sometimes the devices connects correctly (Windows says it's an GT9100 and also Kies tries to connect) but I can't access it 'cause I cannot type in my PIN. Also adb now says I have an unauthorized device connected. So if I can change the last point with adb I think I'll gain access to my data.
EDIT2: I've figured out that I can boot into CWM and now adb says the device is connected as recovery. So I can use pull/push commands but the problem is that i cannot see all files.. trying to find a solution now for this one..
EDIT 3 : I'm recovering my data via the help I got here: techglen.

SO I think the thread can be closed

[Q] Recover dead ColorFly G708

SP Flash tool crashed after the first step (red bar, 100%).
Now when I connect it, it appears in Device manager as DA USB VCOM Port (COM5), but SP Flash never detects it (I am on 64-bit Win7), and I can't upgrade or upload firmware.
So how can I get this device alive again ? Screen keeps staying black. Before it showed battery status.
I tried to connect in while running VMWare, connecting all USB to Linux, and all I see is like below. It goes directly to the DA USB Port (Product 2001). So no preloader. So how can I salvage it ?

I recovered my bricked G708
I had the same issue after trying to flash the 1.04 firmware. After a few seconds my SP-flashtool became unresponsive and left me with a bricked (black screen all the way) G708. Tried al kinds of tricks, drivers and tools but neither the flash-tool not the MTK droid tools recognized the thing upon connecting. Ultimately:
1. I pried the thing open (remove the 3 tiny screws near the SIM and TF card slot).
2. Disconnected the battery (on my device it is not soldered on the logic board).
3. Reconnected the battery.
4. Coonected the USB cable with SP-flash running in download mode......success!
I am a happy camper again, hope it will solve your problem.
Beste regards,
EP
I have one that shows colorfly logo and 100% battery when connected to the pc (win7 x86).
What to do now?

I can connect to the phone no problem in fastboot mode, but in fastbootd mode I can see it constantly connecting and disconnecting in dmesg.
I've added spaces in the output below so it's easier to read. What the heck is going on? I can't move to flashing DE2117 if I can't get it to stay connected.

Try a different USB cable or port.

Fair suggestion. Just tried, 3 different cables in 3 different ports; one front port, 2 back ports (one from each 'stack').
Going to try my mint laptop, see if cycles the connection there too...
The bahvior is the same on the mint laptop. It's an HP 11th gen intel, my main is a 7th gen. Totally different chipsets, that's why I mention it. Probably a similar driver, but I cant think why that would matter. Mint isnt doing anything special with USB, so I assume the OS really isnt to blame. :/

Oh well, I guess you'll have to just search for a solution. Sorry I couldn't find a solution.
