It seems that the link2sd script to auto mount the ext4 part is not taking for some reason. Metal Spring, thanks for the instructions over in the SD10 thread. I tried to PM you but it says your box if full. Did not want this to clutter up the sd10 thread as I may not be ROM related Device: Droid 1 ROM: SD10rc1 Kernel: Deprimed 22.214.171.124 (latest from link at top of "break if you can" thread) SD Card: 32g Class 4 Partition ( all set as Primary): Data:28g Fat32, Apps:1g EXT4, Swap:128mb Linux Swap Here is a summary of the issue for anyone that can offer help: I did the "modprobe ext4" command as SU in terminal and it looks to have took ( no error). I then opened Link2sd and you get the pop up that asks for what format of partition you have. I choose EXT4 and it took this time, without the error that happened without the previous terminal command. It then instructed me to reboot with a notation if you got the message again that it meant that there was an issue with mounting the ext4 partition automatically at boot. So after reboot I opened link2sd and once again I get the initial pop up screen asking for what my app partition format is. I chose ext4 to see what would happen and it gave me the error like before I did the terminal command. So it looks like the script to automatically mount on boot is not taking for some reason. What am I doing wrong or what do I need to do to get this to work? Any help would be greatly appreciated.
