Thanks for the information.

There is no Kurio 10S information in the linux-sunxi wiki yet.
Can you tell us more about this tablet?

Does it have a real hardware FEL button? Is Android easy to root?
Does the manufacturer provide a recovery image?

Without having this information, it's hard to say whether this
tablet is linux hacking friendly or not :-)

I would say, the first thing to check would be to see whether
you can activate the FEL mode. Try different methods listed
on the wiki page:
http://linux-sunxi.org/FEL#Triggering_FEL_mode

Then it makes sense to figure out whether you have a real hardware
FEL button or not. In the FEL mode, you can use the 'fel' tool to
read the device memory. This way you can check the status of
   http://linux-sunxi.org/SRAM_Controller_Register_Guide#SRAM_VER_REG

You can do this by running:

$ fel hex 0x1C00024 4
01c00024: 00 07 00 00 __ __ __ __ __ __ __ __ __ __ __ __

Then try testing different buttons. While the button is pushed, run
the "fel hex" command again:

$ fel hex 0x1C00024 4
01c00024: 00 03 00 00 __ __ __ __ __ __ __ __ __ __ __ __

If you see that "00 07 00 00" has changed to "00 03 00 00", then you
got the right button.

Having a hardware FEL button makes the tablet really unbrickable.
Pushing it changes the boot priority on A31(s) to prefer SD card
over NAND. And if there is no SD card inserted, then the FEL mode
gets activated for USB boot.

If you don't have a real hardware FEL button, then the firmware
in NAND might be checking the buttons status while booting and
switching to the FEL mode in a "software" way. Destroying the
firmware in NAND may potentially turn the device into a nice brick.
Anyway, in the case of non-hardware FEL button, the following may
work for retrieving script.bin (which can be converted to FEX):

http://linux-sunxi.org/Retrieving_device_information#Retrieving_data_over_USB_in_FEL_mode

Once you figure out at least something about this tablet, please
create a wiki page for it.

> as I'm yet to find a method to root the tablet.

As for rooting Android, I used a rather suspicious method. It involved
some Root_Onda_4.4.2_V4.4_LZ.zip file, which is flagged as possibly
containing a spyware/trojan:

https://www.virustotal.com/en/file/9b33e640e7b904dc2d74b1501a9b1536b62bb5ecc3b597ef26b8eaa5d27db7fa/analysis/

Since I could always re-flash my MSI Primo81 tablet to the factory
state with the PhoenixSuite recovery image provided by MSI, I just
did not care about any possible short lived Android trojans :-)

I believe the poor battery life is due to it being an ex-demonstrator
(which is part of why I bought it, _very_ cheap for retail.)

Given that it's only connectivity option is WiFi and 90% of what I do
on my tablet requires internet, disabling WiFi isn't really an option.

I made these points more to describe the quirks of the stock Android
as it shares a lot of them with Android on my other tablet which is
definitely Allwinner's version. Another little quirk is that the WiFi
is inconsistently called WLAN or WiFi.

In my limited experience, this is the first Android device I've come
across that has OTG support out of the box. My A10 tablet has a
dedicated "host" port, my phone has hardware OTG support, but it's
disabled in all but the latest custom ROMs and my partner's tablet
lacks a micro-USB port.

If you'd be so kind as to share which method you used and where you
got it, I'd be most grateful. Every method I've tried has failed to
the point where I'm thinking about whether it's possible to make a
tool that roots devices using FEL / FES mode.

The battery life is not great in my A31s based MSI Primo81 tablet, but
not bad either. It can stay idle for many days on a single battery
charge, and lasts enough hours (have not measured it, but maybe more
than 6?) when it is actively used.

Watch for WLAN power consumption, maybe try to disable it altogether to
see if the battery life improves significantly. The excessive waste of
power may be a purely software issue.

My MSI Primo81 was also not pre-rooted. And it took a bit of effort to

BTW, if anyone cares, both of these MSI tablets have their own pages in
the linux-sunxi wiki:
http://linux-sunxi.org/MSI_Primo73 (Allwinner A20)
http://linux-sunxi.org/MSI_Primo81 (Allwinner A31s)

And patches exist to run the mainline u-boot with the mainline kernel on
them :-)

I bought a 7 Plus over the weekend, and apart from dismal battery life
it's a significant improvement on my crappy A10 tablet (iNet 3FBT in a
Kogan Agora) The Android install on it feels just like my partner's
Asus TF300.

It appears to be a disguised version of Allwinner's 4.2.2 (Jellybean)
Android version as there's a couple of little details that remind me
of my A10 tablet: The most obvious is the notifications for plugging,
mounting and removing USB devices or microSD cards are very basic.
More subtle is that if you hold either of them diagonally by one of
their top corners, angled 45 degrees away from you, they do something
weird: the Agora can't figure out it's orientation, the 7 Plus emits a

Shockingly, it can mount thumb drives connected through an OTG cable
to the micro-USB port.

Frustratingly, it can't decide if the volume down button is a back
button or not.

It's also not pre-rooted.

Sadly the instructions in that document aren't sufficient (or I'm not
skilled / intelligent enough) to actually open the device. I followed
the instructions but couldn't complete step 2 (prying up the display
assembly) as it simply wouldn't lift and I am unwilling to bend the
glass any more than I already have. I'll try to obtain a proper
plastic opening tool and try again.

The versions of that manual (one of which you can download from HP's
own website) imply that this tablet is known by the following names:
 - HP 7 Plus 1301
 - Compaq 7 Plus 1301
 - HP 7.1 1201
 - Compaq 7.1 1201

The 7.1 has a different back case and a TN LCD panel instead of an IPS one.

I also have started considering to get an Allwinner based tablet
since a couple of weeks ago. So far all my devices are just various
development boards and one Mele TV box, which is not very different
from a development board in terms of features.

The first attempt was a failure. I tried to buy a relatively cheap 10"
no-name tablet (but with HDMI and 1GB of RAM), which was advertised
as Allwinner A20 by the seller. But it turned out to be in fact using
an Actions ATM7029B SoC with a quad-core Cortex-A5 CPU (disguised
as "Leopard Gen.I CPU core"). Big disappointment! And a total loss
of trust in this method of obtaining hardware. Though even if the
SoC was the right one, the build quality leaves a lot to be desired
and the screen is just horrible (colors and viewing angles). Maybe
other people had better experience, but I'm not going this route
again.

So now I'm also trying the "big name" brand buying strategy for a
change :-) The HP tablets look nice, but they don't have a HDMI
connector, which is a deal breaker for me. Another alternative are
some nice tablets from MSI. More specifically, these ones:
http://www.msi.com/product/windpad/Primo_73.html#hero-specification
http://www.msi.com/product/windpad/Primo_81.html#hero-specification
On a negative side, just like HP tablets, they have no bluetooth and
no dedicated charger connector. Primo 73 has a TN display (potentially
worse quality) and the Allwiner A20 SoC (worse performance than A31s,
but better support in linux-sunxi and no PowerVR).

HP provides nice service manuals for their tablets, for example
one can google for "HP 7 Plus Tablet and HP 7.1 Tablet Maintenance
and Service Guide". Which provides detailed instructions about how
to take them apart and replace components. It is interesting that
this  HP 7 Plus tablet is supposed to be equipped with 1.0-GB
LP-DDR2 (!) memory. If anyone has this hardware and can extract
the FEX file, it would be extremely interesting.

Regarding vendor firmware. MSI offers PhoenixSuite images for download
and also kernel sources from their website. This is very nice and
reassures the availability of FEL support for unbricking.
HP only provides updates as "update.zip" files to be copied on
the device and taken into use from the "android recovery" menu.
Not sure if this a bad sign and whether the FEL mode could be
locked out or not. Again, if anyone has an HP tablet, a
clarification about accessing FEL would be very much welcome.

Now one more thing about MSI tablets. Google searches for
"Primo 73 discontinued" and "Primo 81 discontinued" find a lot
of web shops, which are out of stock with the "discontinued
by manufacturer" explanation :-( On a somewhat positive side,
the remaining web shops still having these tablets in stock, seem
to be offering significant discounts at the moment (probably they
want to get rid of the inventory ASAP). For example
http://www.newegg.com/Product/Product.aspx?Item=N82E16834152486
seems to offer MSI Primo 73 for $54.99. For the people from
Europe, some relatively interesting offers seem show up and
disappear on ebay.com rather quickly.

I myself have already ordered both Primo 73 and Primo 81 tablets (yeah,
this was a little bit hard on my budget and probably will prevent me
from buying new fun gadgets for a while). The tablets are expected to
arrive later this week. And then I'm going to post more information
about them to the mailing list.

Compared to plain development boards, tablets need properly working USB
OTG, touchscreens, WLAN and also power management features. This looks
like a lot of new fun :-)

Also the "big name" brand's tablets typically don't have a separate
power connector. They are using MicroUSB for both charging and
plugging USB peripherals. But there are things called "accessory
charging adapters (ACA)", and "By using an accessory charging
adapter, a device providing a single USB port can be attached to
both a charger, and another USB device at the same time":
http://en.wikipedia.org/wiki/USB#ACA

Then mainline is going to be fairly easy to port.

The only thing that will need some attention are the clocks driver,
and the pin muxing drivers. I expect the rest to just work (but
Chen-Yu likes to prove me wrong on that part... :))

Also HP 10 claims to be a31 with 2G ram and Mali 400 MP2.

or just search the P/N J6U30PA on hp.com

This does not add up.

From what I've seen, the A31s is a stripped down version of the A31,
so most of the things you'll have to do are similar to what is needed
to bring up the A31.

Unfortunately, I don't think anyone started working on the 3.4 kernel.
