i guess you can not do that with winswup (can not degrade phones version)
i am not sure if you can use this way if you have martech.
degrade with martech tool (its a box for siemens mobile phones), but you have to backup everything befor trying anything.

Winswup v7 should downgrade, I don't see any problem I've done this many times with many CF62s(it just says that there's newer soft version on the phone).
Use original cable.

I have tested this and it is not working. V7 is not accepted by new versions like 83/84/85.

first you must have a v7 bootcore then make a backup of everything on your phone, put v7 bootcore in your phone and run winswup

evan_silbert · 12-16-2004, 22:19

To change the bootcore you should need TP though, right?

If you need TP, why bother downgrading and running Java?

goldfox · 12-18-2004, 12:34

if you have patched before you dont need tp just put the bootcore and flash phone,

ps: you must have a cable for this operation not the same x55

Yes, but you can't patch version 83!!

Hey I got another problem
I tried to upgrade my CF62 to v.12 with Winswup, and it says that can't ping the fone....?
What to do?
Tried with fone switched on/off, with pre-check and not.
