Tinybook support only

Hmmm, my bad, link doesn't pull it up. Simple enough to resolve however.

For the Grantee code enter XAJ
For the Product code enter T706

On the search results (takes a few minutes sometimes), click DETAIL under exhibits and you will see all the available documents.

I know these are syncable in windoze, but i was curious to see what linux would do, or see the device as. I was kind of hoping it'd see it a a mass storage device, but no go. However i got a little bit of info from dmesg and lsusb.

Snippet from dmesg when i plugged in the miniusb cable:

[254075.804087] usb 1-6: new high speed USB device using ehci_hcd and address 14
[254077.760288] hub 1-0:1.0: unable to enumerate USB device on port 6

[254078.582021] usbcore: registered new interface driver cdc_subset
[254090.336041] usb0: no IPv6 routers present

Output of lsusb:

Bus 004 Device 002: ID 0547:2720 Anchor Chips, Inc. AN2720 USB-USB Bridge

Probably of no use to anybody, but hey, i found it interesting.

Okay, so I got a new idea on how to fix this Tinybook of mine... I'm sure the the registry is stored somewhere on the NAND drive outside of the normal area accessible by CE, am I right? So I get this idea that maybe I can access that area by manipulating the registry so that when I plug in the device, it acts like a mass storage device rather than a CE netbook. If I could get to that area, then maybe I could copy the files (nk.nb0 perhaps?) and others off of the NAND drive and use that to somehow to flash my bad T706. Perhaps I could even examine the bootloader to see which files it was searching for when it powered on.

Okay, so I start looking at the registry on my good Tinybook and see that the default functional driver is set for SERIAL_CLASS. I decide that perhaps if I change that registry value to MASS_STOREAGE_CLASS that the device will be recognized not through Activesync, but as an external hard drive. So I make the change, and VIOLA...yep, my computer finds a new external storage drive and gives it a letter.

When I go to open it however, I am prompted that the device is not formatted, and do I want to do it now? Eeeks, I'd better stop before I turn another into a brick. So I say no, and change my registry back to the way it was...and then reboot and all is back to normal. Still I'm thinking that the reason I couldn't see the NAND drive was perhaps due to the way it is formatted, or something to do with the partition table of the NAND drive. Perhaps I need to specify a default drive somewhere in the registry other than DSK1:

So, my question becomes this: Anyone ever done anything this stupid before or dangerous? Or am I the only nut out there? Is it possible? Anyone know of any way to explore a NAND drive via Activesync? Is it possible to make the hidden partitions visible in CE?

That's a bit stupid Rich, but it could be a nice try.

>the registry is stored somewhere on the NAND drive outside of the normal area accessible by CE, am I right?
No. It's stored in .hv files in some partition of NAND, accesible to CE.

>(nk.nb0 perhaps?)
nk.nb0 is the file, containig image, but you will never find such file on the device.

True.

>When I go to open it however, I am prompted that the device is not formatted, and do I want to do it now? Eeeks, I'd better stop before I turn another into a brick
You should instal ExFAT driver's if you are not using Vista/7. NAND is partitioned with ExFAT.

>Anyone know of any way to explore a NAND drive via Activesync?
You should find a way to learn, what DSK: it is. There is a key for chosing the number of disk in Mass_Strorage_Class key.

If you finally get to mounting the NAND partition having .hv files it will be dismounted and you will be able to delete your registry. After reset Tinybook will restore the default registry.

What kind of access to TinyBook do you have? Ask your questions, I will answer them.

Rich: If it helps any the .hv files are stored in the hidden \pocketmory\ partition. Maybe i'll try that mass storage reg edit on mine and plug it back into my linux machine. From there i should be able to tell you what partition (or disk) its located on.

Cheers

Thanks Alt Bass. The Exfat drivers was what I was missing on my desktop. Now when plug in the Tinybook, it shows up like it should...but only shows the \pocketmorey\ folder.

Now I just need to figure out how to specify the other folders on the NAND drive.

Okay, I changed the hkey_local_machine\drivers\usb\functiondrivers\mass_storage_class devicename value from dsk1: to other numbers.

dsk1: is the \pocketmorey\ folder
dsk2: is the \system disk2 folder
dsk3: is the \flash driver folder

Changing to other numbers such as dsk4: dsk5:, etc... doesn't do a thing. No viewable windows from the desktop.

Still this is interesting enough as a learning experience.

After many long weeks and months, I received a letter today from the service center in California for Matsunichi. It says in summary: The T706 is a discontinued item and no longer manufactured or supported. That licensed distributors were notified of this in the fall of 2009 as the last production of the device was during the summer of 2009.

I also received a side note from a service technician that explained that the ROM daughter board was made in two flavors, Linux and Windows CE...both entirely distinct and different and that the flash technique I was describing by holding down the right mouse button while powering on with an SD card in place only installed a few CE6 upgrades onto the device and was never meant to flash the entire device.

Just info for anyone who was interested...

Anybody figure out how to unlock a password on these Tinybook T706 yet? Im afraid I just bought a $50 paper weight..

You cannot unlock the password...that is part of the anti-theft system on them. It is stored in part of the secured NAND memory area on the daughterboard, along with the rest of the operating system bootloaders and main programs.

For the factory to remove it requires the thing be dismantled, the daughterboard removed, and then placed in a special receiver that connects the sub-board to another computer strictly set up for diagnostics and such. They esentially reformat the chip and then reinstall everything all over.

Wow, Im screwed.,. thanks
Is there any value in it? Can Linux or any other OS be put on it??

Wait-wait... Do you mean you have an access to the registry on spoiled TinyBook?

Nope, not on a spoiled one....back when I wrote that post in December...it was just a day or so before my Tinybook was stolen. That was from a good unit. If I could access the registry on a spoiled one, my problems would have been solved!

rrstieb, it is basically a very nice paperweight...just like my other one. Good for nothing. It has value as parts however...and if the only problem is that you are locked out of your because of the password...well that is just a matter of inputting the correct password. Eventually you may find it. If you decide to get rid of it, let me know...I sure could use the parts....though I'm not going to spend $50 for it....

Rich

Okay, finally got it today....sweet, looks like new. But I'm confused....Opera Mini works perfectly with it....I didn't remember Opera Mini working with my other T706...am I wrong?

Funny thing is that no matter where you post a picture from in your underground layer there seems to always be a MP900 somewhere in the background...

This device I am referring to is on ebay now and I bid on it before I knew about the password lock out...Item number: 250794855758
Seller info
Member id ski.330
100% Positive feedback

This seller will not release me from my bid. His add leads one to believe its resolvable. I asked him to change the details to accurately reflect the status and condition of the devise.
We will see...

Hey Rich it may be your old one...
