Here is the current (10-1-08) layout of known Firmware versions for DTVPAL and TR-40 (Not certain what version DTVPAL+ is using or if it's different. Anyone?)
F100: R1647343xxx-- (known)
F101: R164735510x -- R1647405121 (known)
F102: R164747xxxx-- (known? by user: 12none)
F103: R1647493691-R16475208xx (known) (Both DTVPAL and TR-40CRA)
F105: R16478013XX (known? by user: viewer29 from a TR-40)
F106 has been showing up on DISH "refurbed" F101s (maybe other "old" models too) that have been OAD (Over Air Downloaded) by DISH in exchange for "bad" F100/F101s being returned to DISH. Not sure if it is being released on "new" units yet...
If anyone can help expand the range of known serial #s and firmware version I'd appreciate it. Also please take the poll and let us know where you're finding them...
This is an update of an August 08 thread on serial number ranges on Firmware... I'll try and keep this post updated so check back here as more info. gets posted and I add to this posting.
