That's very kind of you Lawrence, thanks.

By the way does anyone have the service manual of NX500? Just in case...

Greetings from Ireland,

I don't have it unfortunately but it is pretty straight forward to dissassemble. In general ifixit would  cover this part in full. What would be nice to have is some file repository just like the xda forum, to have them all in one place. And also thread to cover if things go south.

I'm digging through the net to find file to boot my camera in download mode but I can't find it..

I am also interested in the service manuals. I found quite some on https://www.nodevice.com/service-manuals/vendor/samsung (NX10, NX200, NX300, NX1000, mini) but I want to make a mirror of all NX material for next generations of NX fans.

You can get it from https://nxfiles.nx.tc/files/NX1/Service-Manual/

Before disassembling, I suggest plugging it into a USB power supply with the power switch turned off or charging the battery in an external charger, and to try it again afterwards. Maybe it is just dead battery.

Thank you so much NXFILES

Very comprehensive manual. Thanks for the advice also. It seems not to be the Battery. I will poke around and do some measurements then report back if I find the problem. I am a current Avionics engineer at a major airline and have 50 years of hands on experience in electronics. I have the confidence in digging deeper and needed the manual. Pity  the schematics are not included. That would be so much easier then.  Real pity SAMSUNG pulled the plug on this one. The NX1 was so much more than the Panasonic GH at the time and I bought all the lenses also made awesome 4K video of my daughters wedding etc. Really a big investment wort saving if possible.

Re: Anybody has nx1 service manual? Problem with dials

I've scrolled through the NX1 manual after disassembling a few NX500s (IR modification, sensor replacement), and it is astonishing how many internal parts and PCBs the NX1 has compared to the NX500. I'm still not sure if this is required by the design or was just a series of shortcuts to bring it to market ASAP.

Re: Anybody has nx1 service manual? Problem with dials

Disassembling NX1 is easy, at least if you want just to pull out the mainboard for testing. Only concerning thing for me was how fragile the flex cables are. They sit in fairly tight but to reduce the strain when pulling, most of them have hole for extra grip where you can help yourself with tweezers. I wouldn’t touch the sensor screws as they are holding the sensor parallel to the lens mount. 
My other NX1 has dead motherboard. Out of curiosity I’ve shorted ground with one of the testpoints. The autofocus light started to blink but I’ve freaked out and stopped. Maybe this  could give a clue.. I have flashed bricked android boxes by shorting some nand pins ( enabling download mode ) so this where I got the idea from

Re: Anybody has nx1 service manual? Problem with dials

My other NX1 has dead motherboard. Out of curiosity I’ve shorted ground with one of the testpoints. The autofocus light started to blink but I’ve freaked out and stopped.

This is also documented in the service manual under section "7-6 Main PCB Recovery". If the round pair of pins on the board is shorted, the bootloader of the camera will expect two files, "downloader.bin" and "nx1.bin" on the SD card.

I've done a small bit of reverse-engineering of the bootloader in https://github.com/ottokiksmaler/nx500_nx1_modding/issues/121 but my ARM skills aren't that great. The missing part is the "downloader.bin", I assume this is code that will initialize the hardware, read the "vImage" partition from "nx1.bin" (that contains a linux kernel and firmware flasher) and start it. Samsung never provided these files, and writing them from scratch will be unbelievably hard without any documentation of the SoC.

The second-best option is probably to reverse engineer the first stage bootloader enough to understand the required downloader.bin format, then to reverse engineer the second state bootloader enough to be able to copy hardware initialization code, then to write a bootstrap loader for that. Sounds like a few weeks worth of work for somebody who is versed in ARM disassembly (which I'm not).

Edit: or to get somebody from Samsung or a Samsung affiliated repair shop to leak those files.

Re: Anybody has nx1 service manual? Problem with dials

Hi Georg,

Absolutely. This would  be difficult as hell but on the other instance, I believe that there should be window of possibility to connect the camera under linux terminal just like adb protocol in android phones and sideload the firmware. I also was trying to contact samsung but they flushed my request as well as I was trying to get in touch with chinese repair centres and vendors from aliexpress to see if they can help but they asked me if I can bring my camera to the repair shop lol. On the bottom of the nx1 service manual there are samsung server addresses and I think this could be our source for files but on the other hand I can't imagine that for all those years no one who had access, wouldn't leak it.

BTW Georg, thanks again for the nx500

Re: Anybody has nx1 service manual? Problem with dials

I believe that there should be window of possibility to connect the camera under linux terminal just like adb protocol in android phones and sideload the firmware.

The NX3000 / NX mini SoC has a special boot modewhere it will register as a "special" USB device, but there is no protocol documentation for that. I very much doubt that NX1/NX500 have something similar. There is probably a serial port somewhere, but I don't think that it goes through USB either, and you can't flash 350MB through serial anyway

On the bottom of the nx1 service manual there are samsung server addresses and I think this could be our source for files but on the other hand I can't imagine that for all those years no one who had access, wouldn't leak it.

Those go to the GSPN (Global Service Partner Network), so I assume any licensed Samsung repair shop will have access. Maybe Tigerventercan bring the broken NX1 into a repair shop, have a nice chat about electronics and avionics repair and convince them to accidentally drop an SD card with "downloader.bin"?
