Please inform what
HW and
FW version there originally was
before you start to update it and what was then more new version you try to update.
So where from you have purhased it if it have so old FW that need update. So, what was reason to update?
This need really carefully note about latest FW (and latest is from year 2022!! )
FW update package have Revision history pdf and there read:
"
2022/09/01 1.01.01.03.10 1.
This firmware version only supports V6.1
hardware version of SPD3303X/X-E
Notes:
A. V6.1 hardware version of SPD3303X/X-E do
not support rolling back to the previous
firmware version
B. < V6.1 hardware version of SPD3303X/X-E
do not support upgrading to this version
2. Released P20 version of EasyPower to match
this firmware
Think carefully and logically what this really mean!
If your unit is new and not very old stock it may have HW version V6.1
If this is case, there is nothing to update because it must have just this latest FW
and can not roll back to previous versions!If HW version is < V6.1 then it can not update to this latest!
