[Q] TouchPad doesnt boot - very very tricky - how to solve?

---

Hi,

my TouchPad seems to be in a boot loop, or bootloader is corrupt, dunno.

I am using linux, btw.

This happend:

I did install CM7 since after the first alpha release and upgraded each release without a hassle. I had both OS parallel for a long time dual booting regulary, but using Android more and more often.
Since Christmas then I havent even been in WebOs.

Two weeks ago, I started WebOS again, and got a message to update my software.
I clicked yes.

Then it took an hour or so and the Pad rebooted ..... and got stuck - never came up again since then.

It just stays a bit where the round HP sign comes up, and reboot after a minute or so.
here is the dmesg:

[37240.196350] usb 2-1.3: new high-speed USB device number 8 using ehci_hcd

[37552.534889] usb 2-1.3: Manufacturer: bootie
[37579.309737] usb 2-1.3: USB disconnect, device number 9

I tried a hard reset, and same same happens again:
It resets, the hp logo shows up, then after a minute it reboots again.

So after this I tried to use memboot. but I can't get even into usb mode!
Holding Volume up + Power does exactly nothing! Novacom doesn't recognize my TouchPad.

Holding Volume down + Home + Power does nothing as well - despite throwing this into dmesg:

[37197.120415] usb 2-1.3: new high-speed USB device number 7 using ehci_hcd

btw, webdoctor certainly doesnt recognize my device, neither in linux nor in windows 7 - nonetheless it shows up in explorer as palm device without device drivers installed (yes I did install novacom drivers in Windows as well as in linux).

What to do now? Any hints?

Do the reset again then when it starts to reset hold volume up only.
hopefully that should be you in webos recovery.
Then you can try to flash moboot again because the update does break moboot.

thanks....


had to do it three times, then it worked out!! maybe my vol key is lose?

Anyway, you made my week!! :D
