You mean the change of partition type? That does not require formatting or anything, it is just a flag change.
Well it looks to me your mmcblk0p2 id is set to "empty" when it should be 83 "Linux" Also you mention that you have changed thr FS on your mmcblk0p1 to ext2 but it still says "W95 FAT32" in the partition type.
You can fix those either with sfdisk or fdisk in ubiboot repair mode. (of course being careful)
Everybody is a newbie in the beginning. It is an important lesson I think, to remember that and try to treat all people with respect.
