Hi,
i'm sorry it his has been discussed a lot of times, but i cannot find really clear infos.
After having tried an r7800 with its really easy flash/restore procedures , and after having decided to give back to amazon my r7800 ( defective unit i guess) , i'm considering an acm3200.
Before buying, i'm evaluating all its restore/unbrick procedures. (you never know..)
From what i've learned, acm3200 has 2 partitions.
I can decide from which to boot in 2 ways
- within shell of openwrt with ubootenv set boot_boot part 1/2
- power/cycle(3 times) repeated in a specific way
Ok, i think all this is correct.
Now.
Let's assume i have
partition 1 STOCK firmware
partition 2 OWRT
If my active partition is 1, and i flash an upgraded stock firmware, will it overwrite partition 2? ( i guess yes..)
If my active partition is 2, and i flash an OWRT , will it overwrite partition 1 or 2 ?
Can i decide which partition to overwrite from shell? and from Luci?
So, i guess i cannot keep an updated linksys firmware , as it defaults to overwrite partition 2, but i should be able to keep an updated OWRT, overwriting always partition 2, and keep partition 1 for safety.
If i have 2 partitions with OWRT, is it possible to flash original stock firmware, or do i have to use the USB2TTL interface?
Thank you, and sorry for RTFM questions..
Bye
