How To Perform A Clean Re-Installation? And other questions

[jippalippa]

Hello 
I am deeply paranoid and, even though i don't seem to have any major issue with the camera/magic lantern, i'd like to uninstall the firmware from my Canon 5D Mark II (Currently running the very last nightly build 05th of May), to make a new clean installation of the same firmware.
Is it a dangerous operation?
And yes...i know, i read that, to uninstall the firmware it only takes to go into the firmware menu, but i was wondering if this operation would make a second installation problematic or impossible. and if it was any dangerous, in general.

The firmware itself works (Even 16:9 1600 x 1900 Raw recording works fairly good), but i sometimes have these problems:

1- Occasional interface flickering
2- Sometimes doesn't record when there are 3,4 Gb left on card (i use a 32Gb one)
3- I have some problems with the Raw Mlv playback module...sometimes when i try to view the videos i recorded, it "glitches" the last video file itself (after the camera "builds the index" i occasionally end up with a black video that creates a mess, and forces to empty the card to start working fluently again).
Note that, in this occasion, some .M01 (2,3,4,3 ecc...) files are created, alongside the .MLVs (could somebody explain me what are thi M01,2,3 ecc... files?)
4- Some rare times the firmware says that i don't have the Magic Lantern Help Files on the card...but i haven't deleted a single magic lantern file from the card...

This problems are not too serious, infact they only occasionally stop my workflow, but i wanted to know if this "behaviour is somehow normal (considering i'm using a nightly build) or if it could benefit from a fresh install.

The camera itself should be ok, tried with a standard CF and it works flawlessly.
Thank you SO MUCH for the answers.

"re-installing" will not do anything, in fact, ML is not really "installed". The "installer" (the .fir file) only does two things:
- Sets a flag in the camera that tells the camera to try boot up from the SD card.
- Sets a flag on the SD card that allows the card to be booted from.

ML is loaded from the card at boot time and it runs alongside the Canon firmware (that is, when it boots, it starts its own processes and then releases control back to the Canon firmware).

These are just flags, so they're either set or they're not. The only thing to really do to "re-install" ML would be to simply re-copy the files to your card. I doubt even that is necessary. ML nightly builds are untested so there are bound to be the occasional issues. While it is for the most part stable and very unlikely to cause any damage or interfere with the operation of standard built-in Canon features, there are going to be small bugs like this.


1-3: Help the developers by submitting a proper bug report (how to reproduce, what version, screenshot, video, brand of card, etc.).
4: The nightly builds do not contain the help files. In fact there isn't really any help documentation for the current bleeding edge features of ML, which is why none is included in the nightlies. (Though there has been some progress in this direction)

I have 4 CF cards with ML installed , 2 Lexar 1000x , 2 Sandisk 90MB/s, 60MB/s cards. Just made them bootable with "EOScard" programs and then
copy over all the files to the cards and test each one.
Right now I would now use the nighty builds for the 5D2 for any Serious Work as there are problems.
The older MLV builds are more stable , I use the NB feb16th

Does this build have Raw Recording 2.0 (.mlv) and raw audio? (mlv_snd) These are the 2 main features i'm interested in.

So you are telling me that these minor bugs are somehow normal? I'd just like to know so that i will finally stop worrying.
Thank you so much for your assistance
