Z-Cam E2 Hacks Development Started

storyboardcreativity

Sure, but it will be a bit more difficult because of some things:

I want to save compatibility with Z-CAM official firmwares (if somebody wants to remove modified firmware)
We need to be very careful with filesystem. Any problems with main camera process will convert GREATEST Z-CAM PRODUCT I LOVE to a little brick :D

And one very important thing. I don't know how to publish all these instruments because if they find out how I change firmware, in new versions they will patch these things - it will make research process much more difficult.

@storyboardcreativity Interesting, after checking the concerned sony sensors, some nice options could be added. Maybe some anamorphic 4:3 modes and more color depth. I tried a mavo LF some times ago and i'm pretty sure it uses the same sony sensor as the F6, Kinefinity imho made the best use of it. Good luck ! @Vitaliy_Kiselev About the kick; Sometimes you are too naive...

@Vitaliy_Kiselev

I've found a way to force flash our own firmware without checking it with public key.

Here will be posted all technical info during E2 research process:

Guys, what features do you want to see in E2? It's a Linux machine, I can do anything you want.

zcream

Higher frame rates on e2c

flash

CDNG raw

storyboardcreativity

(REMOVED) - my mistake, it's all ok with ZRAW

flash

So BRAW :-))))))

Recovery mode in E2:

Place firmware file on your SSD (with current firmware version on your camera now)
Connect SSD to camera
Hold power button and record button

Result - camera will reflash it's own firmware

This was very useful for me when I've bricked my camera after wrong firmware modifications

@storyboardcreativity

What will be if issue happen during flashing, like power loss?

storyboardcreativity

@Vitaliy_Kiselev

Did not try yet (and don't want :D).

But I'm sure, recovery will still work (except some special firmware versions with new recovery in firmware file, like 0.96).

Vitaliy_Kiselev

@storyboardcreativity

It is special things to read BGA NAND chips, they are used by people who restore dead SSDs, flash drives and such.

I mean, in case of total big issues and for dumping encrypted stuff.

First Z-CAM E2 mod for 0.93 firmware is coming soon!

It's Panasonic-like recording indicator (red rectangle on HDMI output).

I agree with @zcream. Hack e2c into an e2. Then you'll get their attention.

Vitaliy_Kiselev

@storyboardcreativity

Nice news.

Vitaliy_Kiselev

@kurth

They are now busy with other things.

And E2c differs from E2 in much more than firmware, sensor is different and more.

storyboardcreativity

@kurth and @Vitaliy_Kiselev

I hope, when I make some patches, I'll be able to make a GoPro Cineform RAW codec port for all Z-CAM E2 modifications. It will bring nice compressed RAW to users.

But it won't be soon.

kurth

@Vitaliy...usually people want to hack cheap cameras, obviously since there's a risk.

IronFilm

I've found a stable way to make changes in firmware files for E2

Great news!

If they all use HiSilicon it can be biggest tragedy of amazing small camera company.

Hope not :-/

In 2018, when the e2 was presented, z-cam still lacked the license for a codec. However, it was hidden in an update in mid-2018 and could be activated by pressing 2 buttons at the same time until it was switched off. jason cheng did the same at least 2 times.

because at the beginning a freeze often happened if someone remembers it, which keys are the real ones? it could be helpful because humans ... also jason is a habit animal

every programmer builds back doors you can't help but think you are more intelligent than the rest ... or lazy

storyboardcreativity

Panasonic-like indicator is ready and works stable. Soon packed firmware will be available.

storyboardcreativity

I've found hidden menu in E2 that allows sensor recalibration: Menu -> System -> Camera Status -> press Fn key

storyboardcreativity

New FW version 0.97 is out. But still no info about it on http://www.z-cam.com/

Howdy, Stranger!
