Or upgrading to an older Firmware but with a higher revision number?
I don't have a Flir so I'm just taking a shot in the dark.

Update on my earlier connection issues:
Previously I experienced difficulty talking to my V1.18 after installing the latest Flir Tools software. A fellow forum member kindly uploaded Version 4.0.13284.1003 and now all is well again.
It seems to me that the ability to talk to the camera easily (even through filezilla) may depend on the Flir drivers. I could be wrong about this but in any case I'd advise against updating Flir tools in the meantime.

Arg. OK, the first go around went well. I did the res mod and went well, then the menu mod went well. I went to do the menu3 mod and screwed the pooch. Black screen. I copied the FlashFS and FlashBFS incorrectly, so I deleted them on the camera (through filezilla) and resent the menu3 mod back to the camera. I have nothing but a black screen now. Any ideas how to get those files back (FlashFS and FlashBFS) onto the camera? Many thanks.

You should have done the recommended back up! A little info about your particular firmware and hardware version would help in restoring the missing files. There are plenty of people here that can help you out.

Yeah, I did the backup of the original cfc file, but the video I watched didn't walk me through backing up anything else
. I am on 1.22
Filezilla is showing all kinds of crap on the camera now.
Which of these can I remove to make room for the FlashFS? The FlashBFS copied over, but ran out of room for the FlashFS.

You should be able to drag the new flashfs folder over and select overwrite to replace the one on the camera. Don't remove anything, just overwrite a known bad directory with a known good one.

There is a thread for this sort of thing, i would try to run the firmware update for your version, 1.22 and start fresh. There is no telling if that will work or not but that's what i would do. I am not saying try yo upgrade to a newer version, run the one you already have. There are links in this thread but a few pages earlier.

I've been googleing for hours in this forum. Can't seem to find a fix. When I try and send the FlashFS I get the exceeded storage error..

Hey Heavybarrel, Could you point me to that thread? Where would I find the firmware update?

My backup folder is empty. The only thing I have a backup of is the original cfc file. Am I screwed?
Is there a way for me to get a complete FlashFS and FlashBFS directory somewhere?
Thank you to a member in this forum. He logged into my computer and repaired it for me. Awesome

Took care of it for him through TeamViewer, he was using an e60 cfg file lol

Gentlemen, I am impressed. An amazing hack, followed by Marphy’s brilliant one-click package.
E4 1.1L, SN 63924xxx, f/w 1.22, cal date 24 April.
Sent from Tequipment on 5 June to Australia. Delivered cost A$1135, all inclusive (vs A$1500 local price). A winner.

joe-c's conf.cfc has a new size (112 byte bigger) and ftool outputs an error.
That's expected. The 16-byte MD5 hash has been replaced by a 128-byte Public-Key signature (RSA 1024-Bits). So unless you have the private key or are able to factorize the public key, you can't create a new, valid signature for a modified configuration file.
Patching this signature check in the software is most certainly only possible if you manage to circumvent the CRC check of certain files in "applaunch.dat" which is probably also protected by a Public-Key signature (file "applaunch.sgn").
I expect that it is still possible to hack the camera, but researching this would probably require quite some time and effort.
Is this the same config file that's written to by the camera itself when changing preferences? If so, the code and keys for re-signing the file will be in the camera firmware somewhere. If the firmware's encrypted, the camera needs to know how to decrypt that at boot time.
Time and effort indeed, but the answer is right there in the camera. Unlike say the Xbox 360 where the encryption is buried in the hardware (and even that got reset glitch hacked) this is encryption added where it wasn't before, and all the instructions for doing it will be in that firmware package.
Wish I'd kept up with coding now, must be 20 years since I've used a disassembler.

No, it's the (supposedly) fixed factory configuration.

If I purchase an E4 with 2.1 is it possible to downgrade it to 1.22 or another firmware version that can be unlocked?

Just a short comment regarding hacking a public/private crypto system:
-> find public key stored in device
-> replace public key with own one
-> re-sign all signed stuff
-> have fun
In case the key is hardwired somewhere, then just patch the comparison routine(s).
-> In short: Flir is just setting up a challenge instead of ensuring that their customers get maximum satisfaction.

Who's saying that such challanges are not satisfying to some customers

I just received my E4, and I'm getting ready to do the software performance update. I have a software 1.22 system. Before I go forward with this:
Would it help to film it? Document the process for others? Is there anything I can do to help you folks continue this process?

Back it up, main thing is the conf.cfc file. If you need help I can TeamViewer you
Edit: Let us know what your calibration date is and serial number(you can hold off on last digit) and Aurora will add it to the Useful information thread
