MTX838 vhf error tone after config

[andreic21]

Basically the setup is like this, MTX 838 vhf programed in amateur band. Universal RIB 4008 and P2 PC. After a lot of config to get sistem working properly and without com errors all was fine, programed changes, save in radio all oki but I wanted to change something in alignment section at squelch atenuation, i put some values at working band, F8 at each until one give an error comunicating with radio, after this the radio did not initialize normally giving low tone error and it became unusable. When I load codeplug from radio it did not validate says there is a crc mismatch. F2 for continue and view codeplug freqs ar ok. I figure it that it make an eror whyen saving in alignment zone. I tried to revert changes my restoring a codeplug witch was saved before and witch worked fine but now the software did not recognized features in radio (or codeplug no ideea) saying that codeplug contains features not in radio.
Is there any chances/options to have the codeplug writted forcely into the radio to make it running again ?
