Thanks i’ll take a look into it. I’m a complete novice with this so it’s a bit slow trying to reflash the chip with each change. My main concern is that the compressed rom is actually around 1-2MB/s smaller than the original, so something seems very wrong! Not just the 2k bytes.

I cannot seem to create a modified ROM that will boot. I believe it's down to the partition scheme but I'm out of ideas a this point. I can create an image where the offsets match, but after it's been compressed it's ~2.5MB so when it's flashed the rest is filled with 0's. When it's decompressed...

Hi Joe, yes I tried all of those. I have managed to get a better SOP8 clip and I flashed my modified firmware back and it didn't boot. Luckily I flashed the original dump back and it came back to life. I'm going to have another play with it, but hopefully someone who is cleverer than i can...

Finally worked out how to keep the correct offsets after modifying the firmware. Open the firmware dump with NtkTool Make a note of the offset of partition 1 Use the bfc4ntk.exe tool to extract and specify the offset of partition 1 .\bfc4ntk.exe -x '..\M127 ROM\m127orig.bin' '..\M127...

Using the cli to pack and specify the offset works, so must be a bug in the UI. .\bfc4ntk.exe -p "C:\Users\xxxx\Documents\xxxx\CH341\M127 ROM\CAM-M127-A1-V1.0-ROM\[email protected]" "C:\Users\xxxx\Documents\xxxx\CH341\M127 ROM\CAM-M127-A1-V1.0-ROM\[email protected]" 000af000 However, merging...

I've tried to compress a modified bin with NTK tool and flash it back using an SD card. Curiously if you place any file on the SDCARD with the name FWDV180.BIN the machine doesn't start (screen stays black, no lights). Remove the file and power it on and the machine starts. I assume the BIN file...

Filed some plastic off the clip and managed to read it. I've attached the raw dumped firmware from the M127 machine, plus the unpacked partitions from ntktool. When I open it in ntkMPE I get the following options. I've not been brave enough to modify them and flash it back yet. Looks like the...

Thanks for the reply. I can't seem to get things to improve. If I flip the connector around it seems to short out the CH341a and not even that is detected. Flip it back and it's ok but doesn't detect the chip. I'm at a bit of a loss. There's only really 2 ways you can connect the thing up that I...

So, I dismantled the M127 machine and found it has an MX25L3206E ROM chip. I've connected up a CH341a chip programmer with an 8 pin chip clip. When I attempt to dump the ROM from it though it's never detected. I powered the machine back up and it seems to still function so it doesn't appear that...

Curious. It looks incredibly similar. Even the menu UI appears to be the same. Is it worth me getting a chip programmer and dumping the firmware? I assumed they were all based off the same hardware with (at most) slightly tweaked firmware. I'm assuming these are all variations on the Winait...

Hi, i attempted to use the firmware for the m127 clone which appears to be the same as a Reflecta or Somikon machine. However when I put the firmware on the SDcard and reboot nothing happens. Has anybody had any success with this machine? I suspect it may just need a different file name but...
