[Q] PC does not recognize XOOM after root

Hi all
there are a few threads like this but not quite matching my situation so I will ask here:
Moto Xoom MZ 601 recently upgraded OTA to 4.0.4
a few weeks ago rooted device, kept same OS
ever since then when connecting XOOM to PC I hear the little dink sound indicating a connection
but there is no indication that the drivers are being installed/updated
and the XOOM does not show up under my computer (which it used to)
however there is an MZ600 icon under devices and printers (which there was not before)
but of course cannot browse the Xoom contents from that Icon.
this occurs with USB debug on and also off.
it occurs after uninstall of the moto drivers from PC reboot reinstall moto v2.8.8 driver and reboot Xoom and reconnect.
interestingly when I boot the Xoom into recovery and connect to PC get the connection thunk, the PC now makes like it is
installing drivers but this fails midway thru.
so short of unroot, any ideas how to get the XOOM recognized by PC when connected with USB?
(I did install wi fi explorer pro so can see files on XOOM on PC via wifi, but would still like to be able to work connected with USB)
thanks in advance for advice!!

Click to expand...
Click to collapse
I had already tried the moto 2.2.28
Is the end user driver 5.9 for handset or also for tablet?
seems to indicate handset where I saw it on internet

Any way of de-bricking the xoom through NvFlash?

HI guys,
My Xoom MZ604 is stuck on NvFlash mode. It used to be able to access the bootloader and connect to the computer with the RSD protocol, however I left it alone for a few weeks and now it won't even bootup to the Motorolla Logo.
I have since made a "factory" cable and upon connecting it detects as an APX device and can only connect to NVflash
Is there any way around that? Any suggestion would be greatly appreciated!

[Q] Can't connect to pc; is there a method to get superuser without USB connection?

First of all, hello everyone
I'm trying to install custom ROM's on my TF300T but I can't get my tablet connected to my pc. When I insert the cable the screen lights up but there isn't any option to connect to asus sync, I've tried several things such as changing the usb connection from multimedia to camera but still no dice. I'm on android 4.2.1 10.6.1.15.3 . Already unlocked bootloader with the asus app now I needed to grant permissions. Can anyone help me?
Thanks in advance

No USB access but need to root

I have a tf700 with a strange problem. When I plug it into the computer, it reports there is an error in the USB descriptor and doesn't install the drivers. I know the drivers are installed OK because I have a 2nd tf700 that installs fine. I also tried linux with no luck - lsusb reports nothing when I plug it in, but it does find the other tablet fine.
The error occurs in MTP, PTP, debugging option on or off, and fastboot. It charges normally through the port.
I disassembled the nonworking unit and swapped the port/cable assembly but the problem stayed with the tablet. I also reflashed stock from SD using the stock recovery with no effect.
My goal is to get root access and install TWRP. Does anyone have any suggestions? Is there a way to connect to adb wirelessly without root access or is there an older version of stock I can flash and self-root without a PC?

So it looks like I'm out of luck then?

Computer won't detect my mz601 xoom

I have manually installed my drivers, used different cables in different ports, I have checked usb debugging, I have chosen mtp for transfer on my xoom and nothing has worked. I cannot get my computer to detect there is a device plugged in at all. I just want to be able to install a few different apps on my tablet from the internet and I can't do it. Please help.
Another problem also exists on a different xoom. I cannot start the tablet up because I can either get it to the page with the logo and "Starting RSD mode 3" or if I hold down vol. down it just sits at the logo page.
