Solved for VF2 here.
We got the same issue after change the depleted battery. We went through DEBUG -> Machine type -> Restore the system BUT We lost the SN, therefore the availability to unlock machine options such 4th axis and tap control.
We tried to restore the SN with haastec aforementioned method without luck, because the battery held SN information in the BBU-RAM ( see page 30 in
https://diy.haascnc.com/sites/defaul...df?0=%253F2123.)
Called the local HFO, which did this procedure:
1.- Power on + PRGRM CONVRS button [access to basic OS]
2.- Typed M 6000000 60FFFFF [Clear the BBU-RAM, see manual posted above]
3.- Restarted the machine [Start blinking and power off countdown same way after battery depletion]
4.- Typed DEBUG -> (machine model*). Machine restart on Its own. [*Important: Make sure to input the correct machine type, won't be the same to input VF2 or VF2D]
5.- PARAMS -> P7 (off) [unlock the parameter modification] -> P26 (type serial code) -> P7 (on)
6.- Loaded the original files of settings and parameters via USB. [The machine came with default configuration in usb stick]
To Unlock options (4th axis, 5th axis, fast machining...) you must have / ask to HFO the codes corresponding to machine SN.
It's a good idea to save the parameters and settings in several duplicates.
Hope It helps.
