There were similar topics in the forum, but I wrote my questions again because I could not fully understand.

I just bought a new Solo 4K, I was a Solo 2 user before and was using CCCam. Now I want to use Oscam. I installed the device with BlackHole 3.1.0 flash, reconfigured the channel settings with Tuner.
I wanted to download and install something from the Addons section. Solo 4K gave a green screen, so I had to reinstall BH. So I surfed the Internet and tried to find the most current versions of Oscam and cccam. Which one of these should I choose?

Current Oscams I could find:
1.enigma2-plugin-softcams-oscam.emu11595-arm_1.1-r0_cortexa15hf-neon-vfpv4.ipk

2.enigma2-plugin-softcams-oscam_11.691-emu-r798_all.ipk

3.enigma2-softcams-cccam-all-images_2.3.9-r2-RAED_OE2.0_all.ipk

Current Cccam I could find:
1. CCcam2.3.2 2019-05-07-de.arm

2.ccam info-ccam prio-oscam dvbapi-oscam services-oscam srvid-oscam srvid2 10.02.2020

By your advice, After deciding which version, first of all
I will follow the following yo is it correct?

Cccam ipk with FTP program -> var / / Temp
Oscam ipk with FTP program -> var / Temp
After I put it in the folder, I will install Solo 4K and BH with Manuel install.
Solo 4K Restart:

After I put the Cccam into the file with the FTP program, I will authorize it as follows:
CCcam.channelinfo -> / var / etc (chmod 644)
CCcam.prio -> / var / etc (chmod 644)
CCcam.providers -> / var / etc (chmod 644)
CCcam.cfg -> / var / etc (chmod 777)

Emu files: / var / bin - cccam (chmod 777)
Where to get emu files and are they required?

After I put the Oscam into the file with the FTP program, I will authorize it as follows:
Oscam.conf -> / var / tuxbox / config (chmod?)
Oscam.server -> / var / tuxbox / config (chmod?)
Oscam.user -> / var / tuxbox / config (chmod?)
Oscam.services -> / var / tuxbox / config (chmod?)
Oscam.srvid -> / var / tuxbox / config (chmod?)
Oscam.srvid2 -> / var / tuxbox / config (chmod?)
Oscam.dvbapi -> / var / tuxbox / config (chmod?)

Emu files: usr / bin / cam (chmod 755)?
Where to get emu files and are they required?

To switch between these two
An Addons Maneger program I can find: enigma2-plugin-extensions-levi45multicammanager_8.1_all.ipk with FTP program -> var / / Temp and install it.

I will convert the Ccams with cccam2oscam-1.2 and throw them into Oscam files. There are two files here, User and Server.
So will nothing be written into the other files below?
- oscam.dvbapi
- oscam.services
- oscam.srvid

Emu files: usr / bin / cam (chmod 755)?

Finally, are files like MGcamd, Camd3, Newcamd, Xcamd etc. needed?

In addition, I put my 2.5 hard drive that I removed from Solo2 into Solo 4K, there are movies in it, the device saw as HDD in the menu, do I need to re-install it again?

Thank you.
