Hi maslovsky!
Thank you very much for take the time to answer and the good will to help!!!...
The simple suspend and put in the craddle put the ligth in order, now steady and normal!
If this may help some of the other users, as a report of working, my Z5500 now appears to work fine, but I use the 30-32 rom and my Lexar SD card is formatted in VFAT (for easy access under windows and by means a card RW adapter...), and the initrd.bin of the upgrade is ProtoTKC v1.0, and the standar backup file was restored withouth rename it.
Im thinking about made a test with this new Cacko Zimage 64-0+ProtoTKC2.0+HomeOnSD script but Im not clear if there is a trouble with this combination, and I must make an effort to get the time for doing try and error work because my real work is a little charged by this days,so,if someone tried it or know see something that could make that the things dont go fine/work, well, some advice/alert will be appreciated, specially if it could save some waste of time/efforts...
best regards to everybody!
