Tricks for NOT erasing internal SD when Flashing Well if you guys like to flash very much, you must be aware of titanium backup, to backup everything you need. I used to use titanium backup also, but after my 2nd and 3rd flashing, I became tired of backup-restore cycle, so here is my way to avoid the flashing process to wipe out my partitions and data: comment all lines contain formatting or making filesystem in utscript.sh, just find them and comment them by adding # in front of each line. Here's my sample utscipt.sh from Genesis 2.7.3 after commented: What I did here is just copying/extracting utv210_root.tgz into NAND partition, which handles system root, and other partitions on my SDCARD remains untouch. If you want also don't want your /data not overwritten, just rename utv210_userdata.tgz into something else. I have my own 8GB internal SD partition scheme, ie 3GB for /data and 3.5 GB for /sdcard, because I found sometimes /data just out of space if we only focus on /sdcard to be big. UPDATE: Some ROMs' utscript.sh has two blocks of formatting and creating filesystem, beware, and find them all, comment them all. The clue is sd_fdisk /dev/mmcblk0 and mkfs/mkdosfs /dev/mmcblk0pX
