Hi, I'm trying to revert the firmware to original Lynx version, your support is great and your version of sw is infinitely better than Artatech one, but i decided to return the t68 to Amazon because of the touch screen issues.
In your package I replaced the update.zip file with the one found on onyx website, which is the exact version (2014-06-26_16-16_1.5.0_c3193d0) i had before flashing yours.
The flashing process completes successfully (including "partitioning", "writing system.img" steps, etc.), however after reboot the version is still yours (2014-07-15_20-23_1.6.0_252635f), just as it was simply factory resetted.
What I'm doing wrong? Maybe there is a version check (1.5.0 vs 1.6.0) somewhere?

EDIT:
Ok solved, in the zip package released on the OP, the files written to the device are NOT those inside update.zip.
Instead MfgTool2 looks for so called "profiles" inside the Profiles dir (configured via the cfg.ini file).
In our case the configured profile directory is named "MX6SL Linux Update", and inside it you can find a sort of xml script file (ucl2.xml).
This references the real files written during the flashing process, which can be found inside the files directory.

So, in case somebody else needs to revert to another firmware version, extract the T68_2014-07-15_20-23_1.6.0_252635f_user.zip package (for example in C:\T68), extract the update.zip you want to flash and then move the following files:

android-info.txt
boot.img
recovery.img
system.img
u-boot.bin

to C:\T68\Profiles\MX6SL Linux Update\OS Firmware\files\android

then move logo.bmp to C:\T68\Profiles\MX6SL Linux Update\OS Firmware\files\logo and rename it uboot_logo.bmp (delete the existing file).

then follow the OP flashing procedure.

Bye
Roberto
