HP 39gs bricked? (pressing Reset + and - won't do anything)

[Kevin Ouellet]

Heya, so last week I wanted to try NewRPL on my HP 39gs and liked it, but the key layout was weird so eventually I decided to revert back to the official calculator firmware from the firmware update menu. Unfortunately, at the start of the transfer the calculator froze and none of the key combos and reset button responded, so after about 20 minutes I had to remove a battery and the calculator has not been turning ON ever since (new batteries, with ON+F3, ON+F1+F6, Reset [+] [-] won't do anything)

So I was wondering if there was any alternative besides the aforementioned key combos especially if the Reset + - combo doesn't work or if the calc is toast?
