UPDATED NOV 2012: 100% WORKING ON MINE ON STOCK FIRMWARE.
Instructions follow on ways to get the Android market onto your Coby Kyros 1042 tablet. None of the tools are my own, and I am just posting tools here for convenience. All credits goes to original developers!
Grab the rooter from this thread and root it first:
ARCHIVE 1: http://www.androidtablets.net/forum/...coby_root3.zip
--credit: Requesting Firmware Dumps from Coby Generation 3 Devices
Backup your filesystems using the tools in same thread or through CWM at the end of this post:
ARCHIVE 2: http://www.androidtablets.net/forum/...s-fw_dump2.zip
Get the google package for ICS from here:
ARCHIVE 3: http://goo.im/gapps/gapps-ics-20120429-signed.zip
Download the files on to the desktop,
Get ADB up and running on your machine.
in ARCHIVE 3:
--adb push system/app /data/local/tmp
Type following inside shell:
--mount -o remount,rw /system
--busybox cp /data/local/tmp/*.apk /system/app
Once you have transferred all those files, just reboot the tablet
Also there is a neat way to backup and restore your phones here by vampirefo: Clockworkmod factory image , backup and restore for MID 1024 here: Linux Users, Coby 1042, Root, Recovery, Update, All Without Livesuite,
