Hi A factory reset will not brick the unit.
Either: 1) Your TBolt is blown 2) The cable has an issue 3) The antenna has an issue. For troubleshooting this sort of thing, multiples of each are a handy thing to have. Baring that: 0) Put a DVM on the coax and see if you have bias to the antenna 1) Hook up a TDR to the cable and ring it out both with a load and a short on the end. 2) Put the antenna on a *very good* spectrum analyzer and look at what is coming out. 3) Grab a signal generator that will simulate a GPS constellation and drive the TBolt with that. Since nobody (other than Magnus) ever has the sort of gear for 1-3, and it’s all pricey stuff the simple answer is: 1) The antenna is probably the cheapest part of the setup. I’d swap it out first. 2) The cable is cheap but a pain to run, is it #2 or #3. 3) Hook up another timing receiver to the cable. There are lots of them out there in the $100 to $150 range. TBolts do die. My experience is that roughly 1 or 2 in 50 show up with a fatal issue. Another 1 or 2 show up with a (correctable) minor problem. I have had one drop dead after running for a while.
