I'm facing the same problem. Could you post the tutorial of how to do the downgrade?

edit: this post on raspi stack worked for me https://raspberrypi.stackexchange.com/questions/122429/raspberry-pi-4-wont-pair-to-bluetooth-devices/123914

Pi Model or other hardware: Pi model 4b
Power Supply used: Original from raspberry
RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.6
Built From: Pre made SD Image on RetroPie website
USB Devices connected: none
Controller used: wireless controller from 8bitdo
Error messages received: segmentation fault
Verbose log (if relevant): see next post
Emulator: both "ports" and "lr-pcsx-rearmed" (others not tester)
How to replicate the problem:

launch game from emustation enter retroarch menù settings -> recording enter Twitch streaming URL with Key set udp streaming port ti 1935 save settings (optional) select "start streaming" when you launch game

You could also select any preset ( from low to High , or custom and select the file from previous topic)

@mitu Amazing, thanks. I'll try this later and see if I can get everything updated

pre made third party, I'll poke around, thanks for the heads up

The pi4 drivers are still a wip and they aren't in charge of those. Then there's the slowdowns with emulationstation. I've no stability issues.
I have had stability issues with lakka, though.

@mitu es_configs I restored the backed up version and it’s booting again

I've got an 18 month old so completing games isn't something that happens too often. At the moment in my downtime from tinkering, I am playing:

MonsterWorld IV (Megadrive) - really good platform/RPG

Dragon's Lair (LaserDisc) - great for a quick play when I have five minutes.

Half-Life (PC Port) - never completed it back in the day so intent on doing that.

Killing Time (3DO) - FPS with some live action video and exploring mixed in.

If you have more than one RPi setup then you can simply copy files instead of re-scraping. (And you can create or "tweak" images/text.)

Just noticed I have checked the gz file hash while it was being downloaded (again) and checked the img file from a previous download.

I re-downloaded it using wget and got the right checksum. Thanks!

@ferhound Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

@mitu I have attempted that but you dont have to wait to when using the up down left right arrows, i have tested this and it works before the time runs out

Thanks again, @mitu!

@mitu said in update Retropie 4.6 or Raspbian (old) image:

I'm not sure why you'd want to downgrade to 4.6 is you already have a 4.7 system (even if on Stretch) ? If the upgrade that broke your install is from the Raspbian updates, then I don't see why the RetroPie version would make a difference.

The reasons are complex, as the upgrade to 4.7 both introduced and removed some bug symptoms I was trying to debug on something else I am working on, and others report on RPi3 B+ stretch and RetroPie 4.6. And now I’m back to v4.4 from backup on the same SD card. I’d like to get back to the v4.6 state everything was in... ;-)

I don’t know for certain if the OS upgrade that broke other things came from “apt-get -y dist-upgrade” in the RetroPie upgrade script, or if I ran an upgrade my self.

Anyways, I guess I have to accept my losses, and let this be yet another life lesson on taking an image backup before making bigger changes. Think I got a little carried away in debugging mode... ;-)

This is not guaranteed to work, since some of the emulators have been updated and - as a consequence - some of the scripts in RetroPie have been updated to support it.

Ok now I think I understand better. The complete v4.6 “state” was lost with the removal of the binaries, and is not maintained with information about commit history for external and other source files to compile from the 4.6 install script?

I guess I will use this opportunity to upgrade to buster and RetroPie 4.7 on this RPi3 B+.
This day would’ve come eventually, anyways, and it worked like a charm on my RPi4.

Thanks for a great product and the support!

@Buckey-Jaw said in openBOR can't install libpng12-dev on 4.6.1:

I accidentally ran wget http://raw.githubusercontent.com/crcerror/RetroPie-OpenBOR-scripts/master/openbor.sh -O /home/pi/RetroPie-Setup/scriptmodules/ports/openbor.sh

Accidentally, you say ?

was able to install this with no issue, but not showing ports in ES

You should post in this topic, where @cyperghost added this script, and add a link to the new installation log.

okay impatiently lol, I'll head over there, thanks!

@mitu Hey mitu! Thanks for the suggestions. I figured it out after - I simply tried plugging it into a TV instead of my monitor, and no issues - I can see everything just fine. I think I had the wrong resolution settings perhaps, or maybe it was something to do with the high refresh rate. Regardless, thanks!

You nailed it; once I deleted the shaders folder from retroarch, the update went through without issues.
Thanks!

@Buckey-Jaw said in 4tb external hdd on raspberry pi model 4 running 4.6:

@mitu ahhhhh, I was waiting on the auto copy, it's formatted as ntfs, is that an issue?

You'll have to decide what format you have on the disc - is it ntfs or ext4 ?
Please use the documentation and follow the instructions - you have to choose one of the methods described there and take into account what filesystem you have.

@sad_muso said in Pi 4 Retropie issues:

Hi,

I've just upgraded to a Pi 4 and performed a fresh install of the latest Pi 4 install file (md5: 9154d998cba5219ddf23de46d8845f6c). I know this is still a beta, but I've experienced a couple of quite big issues. Is it the build or something I'm doing?

WiFi search initially found about 8 of my SSID name (for some reason). I couldn't connect to any, but now it can't find any SSIDs at all Retropie has crashed on a few occasions (with 'Retropie has crashed' message) Can't change resolution from 4k to 1080p because I can't get into the resolution menu - it just stays at the same menu level

Have I somehow got the wrong image or copied it to the SD card incorrectly?

I had similar issues

WiFi - I created the file pre setup so didn't have this, however did notice a lot of repeats in Bluetooth when setting up my sixaxis for PS3.

Didn't get crashing

Raspi-config resolution... I couldn't get into this either although I did get a workaround which helped.

@saccublenda Thank you very much. I was just too dump to find it on my own in the first place.
But with your script I get the same Error as Gamer-D.
I am also on RPI4 with RetroPie v4.6
