4.12 / Black screen at start

[MXPHunter]

Tested on PSP 3000. 4.11 works well.

[joel16]

When you install 4.12 is there a config.json or debug.log file created? If

[MXPHunter]

both were created

[joel16]

Can you please let me know if either of those files say anything?
config.json should look normal:
{
"config_ver": 4,
"sort": 0,
"dark_theme": 0,
"dev_options": 0
}

I would edit the config.json and set dev_options to 1 and let me know if debug.log says anything useful

Hmm this is very strange, it seems to work fine on my PSP e1000. I don't have a PSP 3000 to test with. Let me check with someone else.

Strange how this is happening on a PSP 3000, I unforutnately don't have one. I only own a PSP Street at the moment, I'll try to see if I can find out what is causing this strange behaviour.

This issue is caused by plugins, the plugin in question is Custom Home. I can confirm this because I am using a PSP 3000 and the black screen to system crash happened to me when I tried enabling it just now. I hope developer sees this reply

Good day

I have the same problem on a PSP 2000, it goes to a black screen and then shuts down. In my case I have my PSP 2000 with ARK-4.

I had to use the previous version (4.11) to be able to use the application.

Cheers.

The problem sorta like disappeared on it's own on my PSP 3000 I am not sure what causes it. I was also thinking of downgrading but when I opened up the app a few times there were no more crashes.

[joel16]

Unfortunately I have not been able to replicate this issue. The PSP I use don't use any plugins apart from prxshot. However, I don't think there's been any changes between 4.11 and 4.12 that would impact this. I'll try to investigate further whenever I get some more time.

Hey @joel16 ,

I tried CMFilemanager-PSP for the first time and it worked. But, the next subsequent attempts to open the file manager crashed my psp.

PSP Info:

• Model : 3001
• Battery : Do not a functional battery for now, powering it directly using dc jack
• debug.log

  kuKernelLoadModule(flash0:/kd/usbstoreflash.prx) failed: 0x80010002
  sceKernelStartModule(flash0:/kd/usbstorboot.prx) failed: 0x8002013c
  sceUsbstorBootSetCapacity(0x800000) failed: 0x8002013a
  

• config.json
  { "config_ver": 4, "sort": 0, "dark_theme": 0, "dev_options": 0 }

and also there are audio_driver.prx, display_driver.prx and fs_driver.prx, what is the function of these plugins.

Hi @build-error, thanks for sending over the debug logs. I'll have a look at this issue and see if I can reproduce. At the moment nothing from the logs seem off from what I remember. The config also appears to be fine.

The audio_driver, display_driver and fs_driver prxes are kernel plugins required by CMFileManager for elevated kernel level priviledges like accessing flash (fs_driver), changing brightness or turning the screen off (display_driver) and setting the audio frequency (audio_driver).
