EMMC type
I also checked the EMMC type for the two devices. I had recalled they had different hardware.

The device where 10.2.1 installs has a SEM08G emmc and the one where the install fails has a M8G2FA emmc. Is this possibly the issue?

Kernel security patch (and boot failure fix?)
A security bug in the core kernel (CVE-2014-0196) allows users to overflow a buffer via exploiting a race condition in the tty code, allowing privilege escalation (root) by a local attacker.

The attached kernel (source: https://github.com/steven676/ti-omap...ee/cm-10.2.1p2) contains a patch for this bug. Proof-of-concept code exploiting this vulnerability has been public since last week, so it's recommended that you upgrade as soon as possible.

I've also taken the opportunity to land what might be a fix for the reported boot failures on 10.2.1. Please try this kernel and report back if you have a device that freezes while booting 10.2.1.

CM10.1.3 users: you can use this kernel, but it'll break wifi unless you also rebuild the wireless driver modules -- use the kernel posted on the CM10.1 thread instead. CM11 nightly users: upgrade to a nightly from May 14 or later to get this fix. See my post on the dev thread for more information.

That prompted me to check a Nook Color with M8G2FA eMMC (kindly provided by pastordl), and well, what do you know, it doesn't boot. (It's also OMAP3630 ES1.2 and ft5x06 touchscreen, manufacture date September 20, 2011.) The kernel update I just posted above does, though -- hopefully that solves your problem too?

Yes, it does! CM-10.2.1 on the M8G2FA boots with the new kernel!

More kernel security bug patches!
Two security bugs in the core kernel (CVE-2014-2851 and CVE-2014-3153) allow local attackers to gain elevated privileges (root) through exploiting ping sockets and futexes, respectively. (See my post on the dev thread for more details.)

The attached kernel (source: https://github.com/steven676/ti-omap...ee/cm-10.2.1p3) contains patches for these bugs. I do not know of public exploit code for these bugs, but with their wide publicity, exploits are certain to exist soon (if they don't already), so it's recommended that you upgrade as soon as possible.

CM10.1.3 users: you can use this kernel, but it'll break wifi unless you also rebuild the wireless driver modules -- use the kernel posted on the CM10.1 thread instead. CM11 nightly users: upgrade to a nightly from June 6 or later to get this fix.

Today I was throwing on CM10.2 for a friend's Nook Color.
I kept getting a blank screen on boot, your patch instantly fixed it!
Thanks so much.

Is there a fix for the "No SDCard" message when trying to download anything from a browser (or Firefox/Chrome) ?

I followed the directions to the letter and my daughters nook color is now running CM 10.2. it's running pretty good but a bit slow. Is this normal functionality for Cm 10.2 on the NC? If so, should I now flash it with CM 11 to perhaps speed it up a bit?

Hello everyone,

I've been using Mirage CM 7.2 (from 2012) for ages. In 2012. I also tried CM 10 (20121211-nightly) and it was incredibly slow. Everything was dragging. Since then there was CM 10.2.1 in 2013-11-02 which I didn't try. Regarding CM 11 I heard it's even slowlier.

What would you suggest me? To reinstall latest CM 7.2 from 2014. or try CM 10.2.1 (or one of the close working alternatives)? I hope CM 10 from 2013. is faster than CM 10 from 2012.

I'm using email, YT, TapaTalk, just the usual stuff, few simple apps. But CM 10 from 2012. was even extremely slow on screen rotation.

Thanks a lot, folks!
