Are you looking for 5DS/5DS R or 5D (classic)? I don't think pelican ever hosted 5DS firmware. 5D: https://web.archive.org/web/20150304055813/https://pel.hu/eoscard or other snapshots.

I do think it should be okay for the card as it's not being read/written on, so technically shouldn't be different from it being removed as usual. As far as the camera being powered on goes, the lack of power should therefore be minimal and non damaging (same scenario as if you are removing the card say from a card reader plugged into your tablet/computer etc.)

And yea, the battery door trick is definitely a neat idea, let's you take things nice and easy :-)

Identified a tiny risk - with the original procedure, you will be removing the card while it's powered on (edited the original post). Canon bootloader unmounts the card *after* the decryption, right before executing the firmware updating code; that is, after those ~ 10 seconds when you can remove the card. While it's probably OK, I can imagine some cards may not like a sudden loss of power, so there is some slight possibility of hardware damage (correct me if I'm wrong).

He did have 5Ds firmware: https://web.archive.org/web/20180716140322/http://pel.hu/eoscard/

I downloaded it a few weeks ago!

Gonna try this tomorrow.

Right, just checked. My card reader does not power off the card after safely removing it (I thought it does, but tested with a WiFi-enabled SD card), and found no evidence stating that removing a card while powered on is electrically unsafe. No writing takes place while loading the FIR file (some drivers might have written a "dirty" bit to the filesystem, or changed the last access time when reading a file, but it's not the case here - tested). So it's probably safe, as long as the card is removed after the LED turns off. With the CF card, the LED does not turn on in the first place, which makes the procedure tricky.

When inserting the second card, it will stay powered on for a few seconds, before it will be taken care of. It will be power-cycled before mounting, i.e. after the decryption, so it's probably OK, too.

There is some room for mistakes, though. Just being pedantic, as we are playing with expensive equipment of other users.

Updated the installation instructions on the download page; still open to suggestions.

Got a report from a user who tried to downgrade from 1.3.6 to either 1.1.3 or 1.2.3 (he tried both versions, a few times each). The upgrade apparently succeeded and showed a confirmation screen (update is complete 1.3.6 ->1.1.3 / 1.2.3), but the camera was rebooting back into 1.3.6. He used the initial method (card swapping), with a SD and CF card (that's what he had). The failed update was jumping from ~ 49% right 100% (video).

Solved by trying the "battery door" method. A successful upgrade/downgrade should take about 4 minutes. The failed one took about 1 minute.

So, the 1.3.6 updater code (aka the "card swapping" method) is probably not the best choice for downgrading, although it did work for some users.

It looks like using different cards can be an issue for the card swapping method, I have further updated the tutorial on your and other users findings
so it now suggests people use the battery door method for anything outside the "SD+SD" scenario

Also updated the list of compatible cameras, if anybody does any testing with different models please let me know the results and I will update the list

Sorry for crashing the discussion, but I was wondering if anyone had any insight on how to downgrade firmware on a different camera? ie. My camera is giving me an older firmware version error (blah, blah, blah 😑)

You may want to "update" as described by Canon. Just use the version compatible with ML.

Can you please explain a few points?
"Tried everything": Including EOS Utility and the procedure described by Apollo7 in this thread and re-defined by a1ex?
Why are you looking for a downgrade? The only ML build available for M50 is called "fishy" and has very limited features.

EDIT: I don't own an M50 but another Digic 8 cam. And downgrading with EOS Utility is working well.

In regards to tried everything, yes I mean:

* attempt downgrade via EOS utility. once I reach the end of the file transfer, I arrive to a screen that does not initiate the update/downgrade. After a while, my camera shutdown. Upon awakening, I go to menu and attempt downgrade and arrive to older firmware error. Also in my EOS utility, USB functions are disabled as the camera transfer via WiFi. (V1.0.3)  locks the ability to downgrade. I am not able to see the WFT option in my EOS utility. EOS utility v2 does not detect my camera and it opens v3.

*I format card, reset custom buttons and manually load v1.0.2 to sd card, I still get the same older firmware detected error

In regards to why I want to downgrade: yes I would like to test drive the limited version ML. Just to reference the code and see if I can help out “or” by the good graces of the camera gods: an official test version is released 😬

Format card in cam, retry EOS Utility (in-cam downgrade won't work) and follow on-screen instructions in EOS Utility.
If it doesn't work: Link a small video of your cam's screen during installation.

Sorry for the late response, been editing video since April 19 :-X as soon as I get room in between edits, I will post the video. Currently doing post  :'(



*edit: one more thing, should I use a smaller sd card? It seems 16gb formats as fat32 and 32gb formats as exfat. Do you think this would be a reason to why I am unable to downgrade and or install ML? Reason being, when I flash ML Bootable disk, my ML bin file initiates a dump. Even when camera is in off position, lights flash, camera starts and it begins to dump to card. After process complete. I take out put back in the battery, close the door; camera starts to dump again. It’s weird but I will record it as well
