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 :-) -- Best regards, Siarhei Siamashka -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.

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 :-) -- Best regards, Siarhei Siamashka -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.

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. >> 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 >> long string of key presses that confuse Google Play Store. > > Well, discussing the usability of the stock Android firmware is not > the primary topic of interest in this mailing list ;-) But thanks for > sharing your experience. 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.

In my limited experience, this is the first Android device I've come across that has OTG support out of the box.

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.

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. > Regarding vendor firmware.

And if so, has any > work started on supporting them? 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 I don't know if http://www.ebay.co.uk/itm/4-Port-Micro-USB-Power-Charging-OTG-Hub-Adapter-Cable-for-HTC-LG-S4-Galaxy-Tab-3-/371135899746 is a proper compliant implementation of ACA or just has a switch to enable the mode where 5V is provided
