dfs downgrading firmware for mifi 2200 (warning advanced users only)or if your mifi has a death wish)
this is not a solution its just how i have done it.(dfs firmware kinda sucks)
(do not try if you have the demo version)dfs)
I have bricked(dead no lights) 4 mifis to figure this out the hard way. Dfs firmware breakdown
for the 2200 (please note this is for informational use only) I have confirmed
all this info to be correct with dfs team as well.If your device gets stuck in download mode or fails
any of the checked boxes do not restart or unplug it just wait a few seconds and run the amssmodem again
or which ever failed option you checked off to write.


once your connected to your device with dfs go to the download then server tab and download the firmware for your devce
you want to downgrade to in my case the 2200v135.dmf (i was on v167) from the duu upgrade. after the dmf is downloaded click local
then the amssmodem box to the left and click write, if it fails wait a sec then click write again and it will pass the second time.
next check the nw_router and write if it fails wait a sec then click write again and it will pass the second time.


this part is not tested due to me not having the v139 duu if someone can please give it to me i will test it


(Then if you want you can load the verizon v139duu and it will now except the upgrade to v139.)



QCSBLH \
QCSBL ) these are part of the bootloader and other stuff no need to check
OEMSBL /
AMSSMODEM- This is the firmware (mob sw rev)
CEFS2 - This is the memory (esn min imsi mdn and so on)
NW_ROUTER - this is the UI (admin page basicly)


do not cry to me in the comments if you brick your unit please , If you do rich has a fix for you im sure

Thanks for the write up alot of people have been finding that dfs last update wont load 2200 without failing, hopefully this will help peeps that spent money on that tool to get it working. that is a pretty big bug though, you would think they would have tested that before public,lol@ukrains
alot of guys reverted back to the version before the last update sounds like they can update again now
