Firmware Upgrade Clearing Tuning Settings

[aglowgibbon]

I came across this video recommending that you save your tuning file before upgrading your firmware on an APX. The video then recommends that you re-write the tuning file after the upgrade.

I have never done this, and I've never really had any tuning issues. Is something I should have been doing all along? Does upgrading really delete the tuning settings or is it just a precaution?

I've done countless APX firmware upgrades over the past decade from R7 to the current R31, and have never had an issue. I'm sure there was probably a bug in a firmware version at some point that wiped out tuning data, which turned into "ALWAYS BACK UP YOUR TUNING DATA!!1!!!", but to recommend re-writing the tuning data after each firmware upgrade??? Yeah, no. The firmware upgrades take long enough as it is, especially the mobiles.

PS - Just searched the release notes from R1 to R31 and can't find any mention of a firmware bug that wiped out the tuning values. Not saying it never happened, just can't find any reference to it.

This is kinda what I was thinking. I'm not saying its a bad idea to make a backup, but I didn't know if there was any specific reason to do so beyond that.

I know this post is APX-specific, but in previous radio lines there were definitely issues surrounding this. There are also unconventional methods of upgrading/changing firmware that involves software not discussed here that will absolutely clear your tuning values. In my experience if you have to put the radio into Flashzap mode you can kiss the tuning values goodbye. It’s best to just have a copy (you only really need to back them up once) otherwise you will need to take it to a shop or tune it if you ever lose them. No, I have never lost them on my radios doing normal FW upgrades either, but you bet I have them backed up. Why not?
