Downdater Final for 2.50/2.60
Here is the last version of the downdater for 2.50/2.60.
- Added a checking for the AC adaptor. Now it's necessary in order to begin the downgrade.
- Removed the logs, they could cause problems with people with 32 MB memsticks.
Also i want to explain a couple of things:
- The "Disc cannot be read" problem. This is caused because the hardware restart that the downdater does, doesn't restart the umd device. There were a more proper way to reinit the psp, but it wasn't working in this exploit. Not a big problem really, since after you restart manually the psp, the problem is gone.
- DO NOT USE dumps of other firmwares. As important as the files, is the IPL (Initial Program Loader), which is written by a library of the Sony 1.50 updater, that is hardcoded to write the 1.50 IPL.
Or in the message attachment.
