I uploaded the documents. I want to now how to read and rewrite the NAND Flash ROM. Since people can do it, so it was possible.
Here it is the documets I collected. I need to turn on pin 7 to open the NAND Flash and turn the pin 8 before sending the data, the problem is, the Flash memory is NAND and I dont have the equpment.

A crystal ball might be helpful.

without equipment it's very hard.

Yeah its true. Anyway, what is NOR, NSB and eMMC? Its a flash memory type right? My watch using NAND Flash ROM. And not just that, based on the document even its clocked at 52 Mhz it was not had 4 MB for the OS, but 128 MB. It is a universe for us to play with it. I contacted the technician but they did not had the equipment too. THere is option on the watch to reprogram it using only USB cable but I had no driver for it, and had no clue. I only have the Processor pin information, and know nothing about the microcontroler for interpreting the USB data. USB data is 1 bit right? It sent a stream of data to the MC and the MC had an interpreter that control everything even the processor?
Flash tools can read MT6227 processor ROM, but not NAND flash ROM.
The spesification is impressive it had a built in chip for decoding JPEG. But the interface is only for minimal functions. I want to remove the picture from the OS Image put it on the Memory card (I had a 8 GB MMC) and a space about 5 kbytes is enough for inserting a code to load an applications.
Seems I need to contact Thomas http://arm.flatassembler.net/
But I cant offer anything to him, except the documentation I had. Ahem, from stealing it. But if allowed to spread as long as I did not take any charge, for commercial, non-reproducing it and for education only. Ah yeah, he already had it too since I had it too.
I lied, I did not stole it, I downloading it from ARM website. Just wanted to impress you. ARM webiste is down for maintenance, sorry guys. Im really curious on how to rewrite the OS.
