Some issues in Evilnat 4.92.2 [PEX]

I have Evilnat 4.92.2 [PEX] [BETA], IRISMAN 4.91.2 and FileZilla Client installed and I'm having the following issues:

1 - The PS3 beeps thrice and restarts when exiting IRISMAN after holding the "PS" button and clicking "Yes" after uploading files from the PC to the PS3 with FileZilla Client and an USB device connected to my PS3;

2 - The PS3 often freezes when returning to XMB from IRISMAN after pressing the "Circle" button and clicking "Yes" after uploading files from the PC to the PS3 with FileZilla Client and an USB device connected to my PS3, and when clicking the PS3's "Power" button, the PS3 beeps thrice and turns off;

3 - Sometimes, the PS3 also beeps thrice and restarts after exiting a game or app using the "PS" button and clicking "Yes" with an USB device connected to my PS3;

4 - There are times when the PS3 beeps thrice and restarts in other occasions as well;

5 - Occasionally, when using FileZilla Client to upload PKG files from the PC to the PS3 while IRISMAN is running, the uploads start very slowly (like under 1 MiB/s) and take some time to reach the right speed (18/19 something MiB/s). If I close FileZilla Client before it reaches it and run it again, it reaches it right away;

6 - If I leave FileZilla Client connected to the PS3 for some time, I can't reconnect to it until I close FileZilla Client and run it again. This also happens with the PS2, PSP, PS Vita and PS TV;

7 - After clicking "Check File system" in "Service Tools" under "* Custom Firmware Tools", the PS3 just restarts to the XMB;

8 - I can't decrypt encrypted PS3 ISOs in Evilnat. After uploading the encrypted PS3 ISOs and the matching key files (both have the same name) to "/dev_hdd0/PS3ISO" and clicking "Decrypt 3k3y/Redump ISOs (HDD)", a message appears saying "Could not find any encrypted ISO file". The same thing happens if clicking "Decrypt 3k3y/Redump ISOs (USB)" after copying the encrypted PS3 ISOs and the matching key files to the external HDD's NTFS partition's PS3ISO folder. I have the 80010017 error message when running encrypted PS3 ISOs;

9 - My PS3's "Power" button indicator blinks green when playing PS1 BIN/CUE games and PSOne Classics and it only stops until I restart the console. I've checked the temperatures and they're over 70.° degrees so does that have to do with this?

EDIT: If I close FileZilla Client after uploading files from the PC to the PS3 or if I don't connect an USB device to the PS3 before uploading them (or if I take it after uploading them), I can exit IRISMAN after holding the "PS" button and clicking "Yes" without the PS3 beeping thrice and restarting and I can return to XMB from IRISMAN after pressing the "Circle" button and clicking "Yes" without the PS3 beeping thrice and turning off.

EDIT 2: I ran PS3DEC Simple GUI, chose the encrypted PS3 ISOs with the matching dkey files (I had to download the latter since said key files had the "key" extension, not the "dkey" one), it created decrypted PS3 ISOs and after running them on the console, I was able to play the games without any error message.

I find it odd PS3DEC Simple GUI works with dkey files when the "Decrypt 3k3y/Redump ISOs (HDD)" and "Decrypt 3k3y/Redump ISOs (USB)" settings apparently work with key ones since they mention them. Anyway, if using both "Decrypt 3k3y/Redump ISOs (HDD)" and "Decrypt 3k3y/Redump ISOs (USB)" settings with dkey files instead of key ones, it still doesn't work since a message appears again saying "Could not find any encrypted ISO file".

EDIT 3: According to this, it's possible to decrypt encrypted PS3 ISOs on Evilnat and on the fly (so, the "Decrypt 3k3y/Redump ISOs (HDD)" and "Decrypt 3k3y/Redump ISOs (USB)" settings aren't required since the games work right after being ran) but webMAN MOD is needed and I don't want it. Also, key files are used instead of dkey ones.
