Like a lot of other users, my Sansa Clip+ player died on me recently, flash corrupted won't boot anymore.
I was browsing around Amazon and the AGPTEK player was advertised as "rockbox compatible".
There was even a piece of instruction on the product's page
Compatible with Rockbox system by update the latest Firmware.Note: you need to go to agptek com-blog, input"ROCKER Firmware Update" in search box to find the latest firmware to update your mp3. Followed the instructions which leads to this download

https://drive.google.com/file/d/1wKUaxM4Zxs2850x5jeVBLI4DvbtbQTCJ/viewThese are the files I used to update the AGPTEK player with rockbox
I eventually updated the .rockbox folder with this version, agptek Version: ed269affb5-190208.
Here are the results of the testing I've been doing the last couple of days.
Video: mpeg1 and mpeg2 files are playing but you have to enable FPS display, if you don't the image won't get updated but the sound still works
If you don't enable FPS, you can still get a jittery playback by pressing pause/play, image will freeze when the controls disappears.
Here are the ffmpeg commands I used to generate the mpeg1 and mpeg2 video files.
mpeg1: ffmpeg.exe -i "RC-s8e1.mp4" -s 160x120 -vcodec mpeg1video -ar 44100 -acodec mp2 c:\RC-s8e1.mpg
mpeg2: ffmpeg.exe -i "RC-s8e1.mp4" -b 3000 -s 160x120 -vcodec mpeg2video -ar 44100 -acodec mp2 c:\RC-s8e1-2.mpg
Doom: I've put the rockbox.wad doom.wad doom2.wad, tried both with the same result, screen will freeze on the rockbox menu and then you have to hold the power button to turn off/on the unit.
Mod files (tracker music): I've had mixed results, .mod extension seems to be working fine, I haven't had any "new" issues with this player. Back on my Sansa unit I noticed that the total time and elapsed time were wrong and the song wil just loop forever, you had to manually press next to go to the next song, seems to be a general issue with rockbox.
XM files don't seem to be working, I get this message "Failure loading sampleinfo"
IT and S3M opens in a different player, if you try to quit it will bring a segmentation fault. If you let it go on it will go to the next song automatically but will eventually crash, with a segmentation fault, after a couple of songs.
Midi: some files work, some don't, I haven't done a lot of testing but I noticed that if the midi file has a lot of tracks, it triggers a segmentation fault. I had more or less the same results with my Sansa player.
Game music: I've tried NES, SNES, MegaDrive (genesis), Sega Master without any problems.
I tried to connect to the unit with ADB, after installing the driver (manually) I was able to start a shell. I am no ADB expert, used it twice before, the display seemed weird, here is a sample output of the command 'ls'
←[1;34mbin←[0m ←[1;34metc←[0m ←[1;32minit←[0mOther "problems" reported on this thread:
Static/click sound: I haven't noticed it with while using my cheap KOSS earbuds or my "higher end" Beyer Dynamic BT 770 80ohm
lcd screen on/off: I can still see the screen with the backlit off, but you need a good light source to notice it. tried the echo 1, echo 0 command, I can still see it. I don't believe it's a real issue though.
Seems like a long post, I joined the forum 2 days ago to hopefully help the developers.
I was overwhelmed with joy when I found out that there was support for new players.
I would like to give my eternal gratitude to wodz for continuing his work on this player.
Cheers !
