Page 1 of philips dvdr80 - firmware upgrade and multi-region hack

Hi
I purchased a Philips DVDR80 recently and store kindly performed a `remote-control` hack to enable multi-region. I now want to apply the latest firmware upgrade from Philips and am concerned it may overwrite the hack or even worse damage the machine.
Has anyone thoughts or experience on this matter?
Thanks
K

Hi i have had no problem, I did my hack with the oneforall remote and downloaded
the software from www.p4c.philps.com, and burn onto disc, the only problem i have
(which is nothing to do with the software) is that i cannot play DVDs from regent 1 with
RCE,does not want to no :(
