So I've recently picked up my PSP (Phat White one) after putting it down for some while and decided not too long ago to buy myself a Pandora battery along with a new 1GB memory stick, since I initially couldn't find my awesome MMS.
Whilst setting up Time Machine with DDC v8 + GEN Pandora prx is simple, the real problem is that I can't boot into the 1.50 FW neither can I activate the recovery menu of 3.40 OE; each time I try to access this, the orange light keeps flickering on and off. I have tried formatting with various methods and making the stick from scratch on 5.50 GEN-D3 and on 6.20 PRO-B5 as well as 5.00 M33 from MMS, but I still cannot get those firmwares booted from the created MMS.
Funnily enough, after refinding it, my awesome stick has no problems whatsoever, even though it is a fake (MagicGate status "Unknown"). The one I'm using also has the same problem, so maybe it has something to do with the stick?
