After some sdcard edits, got my scope back.
I believe this older droid uses sdcardfs on android_meta and android_expand partitions. sdcardfs apparently is a layer that does not use block addressing.
From what I know of and read about sdcardfs, ext4 is the underlying filesystem. Yep, android is as goofy as they come.
Good to hear that. Make some backup of working sd card image (at least in two places) and when You will need to do some write test on image, then dont forget to make another copy for that.
Speaking of ext4 - that is great file system, probably best one in world. Long time ago I was using ext3 and after I decided to use brand new ext4 it was crazy fast, especially with fsck (seconds instead of hours). Some people can say ReiserFS is better, but its not longer developed, because currently Hans Reiser is in jail.
Yes, I would like to see a photo of the back of the board. Thank you...... By the way, it is not necessary to remove the radiator for this.... Your method is good, but when updating the firmware it needs to be repeated... I would like to permanently change the HW configuration.... configuration resistors are located on the reverse side boards.... Thanks again!!!
Damn... After upgrading by GEL file, its just two lines of code - how often You do updates?
Currently Im working on some software changes, and right now probably I have some "small" breakthrough.
