Nice work! I've flashed it yesterday when you posted it on goo.im and it's running nice so far. Got sod but I put wifi to always on, anyways it doesn't seem to drain too much battery. Also maybe you should update the recovery as this one cause 0 folder nesting when flashing(I got emulated/0/0/0...) and this is repaired with newer recovery, I don't remind wich number. Everything else seem to be working perfectly, some little strange thing but I think it's due to CM nighlties and could be working correctly later. I'll thank you so much for keeping our device alive. Keep it going.

Edit: The recovery issue is fixed since cwm 6.0.2.3 and we got 6.0.1.1 so that's why it's nesting but that isn't dangerous or anything, it can be deleted and the data are simply at the bottom of the 0 folders tree.

Hey, kaschemme, thanks so much for the update! I am looking forward to giving it a try, although I do use the USB Storage function a lot (it's the easiest way to copy movies onto my K1), so I might wait until after my vacation to do the update. I'd also like to see how the GPS functions are working, since I use my K1 a lot when I go geocaching. But it's wonderful to see that the K1 is still moving forward! :good:

USB connection to a computer do work for me on ubuntu 13.04 better than it ever worked. I think by USB storage he is meaning USB OTG, like plugging a usb key directly in the K1 with the almost inexistant lenovo adapter.

Right, USB host support (attaching a USB flash drive to the K1) is exactly what I mean, and what I use. I was fortunate enough to get one of those non-existent adapters.

There isn't nvflash folder in kaschemme. For me kaschemme/CM10/nvflash/nvflash_CM10.1_Wifi_Kaschemme_v1.zip download without any issue.

The problem is the NVFlash links.
The file is not at http://goo.im/devs/kaschemme/nvflash/nvflash_CM10.1_Wifi_Kaschemme_v1.zip
The file is at http://goo.im/devs/kaschemme/cm10/nvflash/nvflash_CM10.1_Wifi_Kaschemme_v1.zip

Means it is inside the CM10 directory :D (linkage truncates whole sentence)

Thanks, ti-pich! Thanks Kaschemme!

You are really lucky then, this is probably the only thing missing on this tablet, and that's why I'm waiting for google to release their nexus 7 full hd with a regular micro usb. Anyway, sorry I misunderstood what you said.

Kaschemme,

nvflash_CM10.1_Wifi_Kaschemme_v1.zip is corrupt. Downloaded 4 times. :(
I downloaded it, and it does appear to have the correct MD5 hash signature, but if I try to open or extract it using Windows Explorer, I also get a message that it is invalid or corrupted. However, if I use 7-Zip, it seems to open and extract with no problem. Perhaps it was built using some type of zip compression that isn't supported by the built-in Windows compression tools?

Thank you. I was using winrar which is what I always use. In any case, I flashed this rom's cwm version over krook1's nvflash starter v2 and it worked, but gives me the same errors as krook1's version 6.1, which are random apps closing with no explanation whatsoever... Not even a "sorry, xyz app has forced closed" message. Keep in mind this is a fresh install.

This flash also started complaining that email had closed right from the start, too. I hope this helps you guys...

Take a nandroid backup and try doing a clean flash (factory reset then flash), in case you did a dirty flash.

Would you please let me know which version of 7-zip you used to extract the files from nvflash archive?
I tried 9.20 and 9.30alpha and both give me 'unsupported compression method' :(

    CM10.2 (Android 4.3)

    I just want let you know, that I'll delete my CM10 build system (not CM10.1). Yesterday came the information about CM10.2 (Android 4.3).

    Our current source code isn't really the best for the new system. I know a couple of things what must be in and that could be a problem.
    If someone is out there to work with me on the new CM10.2, he /she is welcome.
    Cross your Fingers for the new CM10.2 on our K1.
