All GIEC 5300 from this deal are already fully TNT activated. They can`t If you update your player with newer TNT firmware the activation still stays on.
Since G5300-Pioneer Firmware does not work on these newer G5300 players, you don`t need to worry for Pioneer activation files.
Because newer G5300 can`t be updated to the Pioneer Firmware, the seller could not sell it to you. Tocinillo did not know that at time, he just asked for "Jailbreak" version and mentioned Pioneer. As TNT is the only currently available jailbreak, the seller thought that's what you want. This updated version of the G5300 just arrived shortly before the group buying happend. So nobody was aware the differences and the consequences at that time.
I was not involved in that order process. But offered support with the Pioneer FW and activation to Tocinillo and paid the postage my self so he can test my Player for his Forum.
I don`t know for sure. But he has the Pioneer SDK + key, as he can change the firmware and also jailbreaks himself.
Still only TNT firmware will currently work on these newer G5300.
You can never be sure that something is impossible, I quote literally your phrases '' Since G5300-Pioneer Firmware does not work on these newer G5300 players '' '' Because newer G5300 can`t be updated to the Pioneer Firmware ''
the manufacturer has been able block the firmware boot so that they would not introduce other non-original or non-TNT firmware,
but that does not mean that it cannot be done, there are other ways to program the emprom from another route through the MTK8581 microprocessor, with the ch340g TTL usb interface ( which if it has the motherboard of the M9702)
I have not been able to do it because before I have to make sure in several aspects, first that the hardware has not been changed in this update of the giec g5300 in a cut of the empron (from 4gb to 2gb as it happens comparing it with the M9702) (and that they have not also changed the ram to less capacity),
second have the pioneer firmware adapted for giec full version (not the demo, which is in this thread) and then the appropriate programs for To this end, previous backup copies of what is currently installed (TNT firmware + jailbreak, to be able to recover in case the pioneer firmware is not stable or does not work) in giec g5300,
as well as I am not the person anymore adequate since I do not have all the necessary knowledge for these purposes, there are people much more prepared than me who will surely know how to solve any problems and surely they can install the pioneer firmware to our giec g5300
