reflashing a box cos you've lost pay channels is pointless.There may be an issue with a cam, some versions of mgcamd would freeze & lock intermittently
and a restart would return them, using updated mg.cfg usually remedied. In my opinion oscam is the better cam to use, albeit when Sly introduced 'half keys' a couple of years back ,some versions of oscam struggled to clear. On the plus side Oscam has benefits, it is the more supported of the mainstream cams,& the most up to date. you can use cam interface via openwebif, to verify that you are actually connected to your providers service,with a little reading you can see why so, if you're not connecting, is server blocking you, is there a problem with your reader or configs. Many servers like to push 'all good here, must be your side' with oscam you can forward your live log to him, of course you can do this with cccam too, but the required configs would have to be found, as cccam primarily an easy to set up client cam, usually used only with a CC.cfg file. Most line issues stem from your local network, or a server issue, when you reflash a box you're rewriting all when you could solve you're network issues without. Simply reboot your entire network ,all off then, modem/router, then your box after about a minute later, hard wire rather than wifi being preferable, homeplugs are good but can lose their pairing too
With cable always use good cabling & secure connections & quality splitter if required, in my case due to poor signal I had to use an amplifier
