Hello, I'm new here and to the ps3 jailbreak scene. As I've only recently did it to my ps3 just this summer. Well I will disclose that my ps3 has a problem with booting, as it sometimes shuts down when I try to boot, giving me 3 beeps and a blinking red light, even before the blue light from the blue ray reader comes up. I just force myself through it until it gives in and boots normaly. I've tried most things to try and fix this problem but to no avail, probably would have to replace the power source. Anyways, my current problem is the following, I want to play PS2 games through ISO files, but my ps3 hard crashes (completely shuts down and stays with a blinking red light) at random, can be while booting up the game, or half an hour in game. It even gives an internal sound like a back switch of some kind being flipped, trying to describe the symptoms as best I can here. It also has trouble to start reading/detecting discs, but that's probably due to a faulty/old laser. Okay so, I first installed the cfw REBUG REX/D-REX 4.82.0 with Cobra 8.0.2 (iirc), and this problem was nowhere to be seen at the start. I even managed to fully play through games multiple times. Only after a couple months this started happening for no reason, as I didn't update anything. So naturally I went online to try and search for solutions for this, and although I didn't find anyone talking about these games hard crashing their ps3, I tried all the possible fixes I could find, and here is a list of them: - Played around with rebug settings, testing with Cobra on/off, and rebug/normal in the rebug toolbox; - Used multiMAN, Managunz (with every different setting) and webMAN MOD; - Upgraded to REBUG REX/D-DEX 4.28.2 as well as Cobra to 8.1 and the latest toolbox; - Retried testing with Rebug/Normal and cobra on/off; - Tested with ps2 games that weren't really verified in the compatibility list, as well as fully playable ones; - Tried to lower the temperature to around 60ºC (was around 70ºC before); - Tried using the PS2 classics way, but couldn't make it work, because whenever I tried to mount the encrypted image with the PS2 manager app, it always presented me with "an unexpect error occurred" and wouldn't do anything, tested with 2 games (1 unlisted and 1 playable) same error. Also tried mounting with webMAN, while it worked, the crashing issue still persisted however; - Verified the MD5 of the ISO files, tried with both valid and not valid ones; - Tried doing restore file system, rebuilding database and restore default settings; These are all the things I've tried doing, maybe I'm forgetting some stuff but I'm sure I'll remember if it gets brought up. It is worth mentioning that whenever it hard crashes, and I boot up, it never asks for the file corruption check. Also the fact that this only happens with ps2 games, it never happens with ps3 games, and haven't tested other games like ps1, psp and stuff. I'd like to avoid the thermal paste option as I have no experience whatsoever in soldering, best I did was opening up the machine and cleaning the laser. I tried everything I could think of and find, nothing seems to be working nor telling me where the problem lies. Hopefuly someone here is able to help me with this issue, I'm still a newbie so bare with me. Thank you in advance!
