Hi, thanks for the development for the lenovo A1. I had been using it for months. However, there is 1 small problem. When i plug the A1 to the windows 7 pc, it did not show the USB mounting and the windows 7 also did not show the mounting of the A1. Not sure is it the hardware problem or is it the software problem.

I noticed this issue when I wasn't using an SD card...

Try going to:

Settings>Cyanogenmod settings>Application settings

-and tick the "use internal storage" box. Then reboot.

Then try again. Should fix the problem **IF you don't have an external SD**. :)

So I went ahead and compiled JUST the uimage into a little 1.2ghz kernel (apparently there's a new version that fixes reboot. Looking now)... (STILL won't reboot unless I do it via CWM)... Then everything is fine. Not a big deal, just a little pain in the ass. Especially if you get a random restart... Then it can get dicey.

Here's the download... 1.2Ghz Overclock Kernel (flash with CWM) - (REMOVED DUE TO BOOT ISSUES see this post for download link of fixed kernel http://forum.xda-developers.com/show...&postcount=150)

-and here's a CWM flashable .Zip of the stock kernel so you can go back if need be... http://www.mediafire.com/?o6c67k927i23y2v

^I can confirm flashing the stock DOES fix the (re)boot issue caused by the overclock kernel. Hopefully this .Zip saves some people from un needed wipes if you have to go back.

I was hoping someone with a little more know how than myself could take a look and see if it's something dumb keeping it from cold starting and rebooting. Would greatly appreciate any insight... Thanks!


Can someone please upload the uImage with the boot fixed please? I'll compile it into a CWM flashable .Zip... Thanks!

It doesn't happen at all with mine

Did you see anything in the status bar of the A1 after you connect the A1 with Win7?

Exclamation custom kernel now included
from now on, our custom kernel will be included in the nightlies.
that means a new kernel will be fused upon flashing cm7.

please consider updating your u-boot to the new fastboot included version by gmarkall (instructions in first post).
in case anything goes wrong you can easily recover everything via fastboot without having to build an sdboot package.

any change making it into the kernel repo does NOT necessarily mean that we already included it in the nightlies. we are pushing prebuilt kernels to the device repos. i.e. keep an eye out for commits to the device repo like "update prebuilt kernel".

have fun and pls report back.

cheers

Question
Couple of questions.
Are the new nightlies with your kernel safe to use with CWM 5.0.2.7. I like having both cards so I have not upgraded.
What does the new kernel give us over the stock kernel?
Last but not least if I install this kernel and want to go back will installing an older version of CM7 do it or do I need a special zip?
