Hi all! Super sorry to bother if this has already answered, but I'm very new 510 box mods. I actually would like to get a Thelema Quest 200W (dual battery) for the purposes of using a 510 based wax atomizer, but I understand that such devices really need TCR. To clarify, as I understand it, although the Thelema Quest doesn't support TCR with stock firmware, flashing it with Arctic Fox enables TCR mode on the device? Also I'm reading that apparently the chipset has changed, so I take it this is only possible with the older models of the device before the chipset was changed? Does anyone know when the chipset was changed? I believe I might be able to purchase one of the older models. I noticed it appears many sites are now selling the Quest with all black buttons, but it appears there is an older model of the Thelema Quest 200W with color matching buttons (blue/red/silver buttons), I assume this is the version from before they changed the chipset? Thanks to anyone for help with any of this, I super appreciate it and thanks to the NFE guys for making custom firmware for devices like this.
