Downgrade the bootloader to install a CyanogenMod ROM
The DOWNGRADE process that we previously provided here is no longer recommended. Please visit our “NVFlash for Dummies” page for the proper guide.
CyanogenMod ROMs are normally based on the 1.1 bootloader branch. If you have the newer firmware, then you must downgrade it before you flash the standard CM7 ROMS.
If you do not KNOW your bootloader version visit: Check Bootloader Version on GTab Before Root!
Notice: If you have the 1.2-4349 firmware, you should still use the “UPGRADE” procedure. This firmware includes the 1.2 boot loader and it appears that all newer ROMs are going to be built for that version. If you want to flash the newer 1.2bl – based ROMS, then visit our ClockworkMod 1.2bl & Honeycomb on GTab page.
