Creating full clone of MR1100 flash, BUT crashing router grabbing 2 pieces, any geniuses out there?
Posted: Tue Jan 17, 2023 2:41 pm
I've managed to successfully clone 18 out of 20 pieces of the MR1100 flash (MTD bits), but when I try to do anything at all to mtd1 and mtd2 the router immediately reboots.. I imagine it's because I'm pulling from a live device and have been banging my head against the wall playing around with UBIFS and MTD bits in general, but have had no success. If anyone out there is a bare flash guru, would appreciate any pointers on how I might grab these last two pieces.
Thanks!
It's mtd1, "mibib" and mtd2 "efs2 that are the problems. Here's what my df looks likecat /proc/mtd

mtd19: 00740000 00040000 "persist"
Even running "fdisk -l" just to take a peek at those two results in an immediate reboot. So, again, any thoughts much appreciated.df
