F-lash-ast forward to about a week ago I bought the same watch, and to my surprise, I was able to extract the ROM successfully AND download it to my near brick v8 smart watch!
You’re probably wondering how? In about a week, I’m going be making an “update” video on how-to use these Flash Tool and extraction methods because when I initially started I had no clue what I was getting myself into. Before I finish this post and potential video, I will list some things I did that might help you out:
Backing up ROMS
-when entering a scatter file using Flash Tools, it doesn’t matter what you “upload to backup”. This is important because even an (red) ERROR message (near the four files you uploaded.) May look bad, but it’s NOT! All in all, you’re trying to back up NOT download yet. So if you see an error, you’re kinda heading in the right direction. (Leave it red)
After uploading a spoof scatter file, you have to use the read back service on Flash Tools. Remove whatever you see there and add and save to wherever you want to save the ROM file. It’ll then prompt two addresses you can alter. Don’t mess with anything except your LENGTH address. I was able to retrieve some info on the FAT address by highlighting over near the bottom on the Flash Tool app; that’s the info you want to use. I believe for my version, which was made in August 26 2018 it’s chipset/MTK6261 FAT LENGTH address is 0x00400000.
Once you’ve done that, use that ReadBack Extractor App to extract and rebuild the ROM file and it’ll give you 4-5 files to use for Flash Tools to DOWNLOAD firmware to your v8 smart watch.
And that pretty much wraps up what I did to successfully backup my “NEW”v8 smart watch rom and DOWNLOAD it to my other “BROKEN”v8 watch. Quite honestly, I didn’t want to buy another smartwatch so I refunded the BROKEN one and was still able to keep it, to just fund the new one...WHICH has the same firmware! The only thing now is to find a IMEI recovery tool to fix your IMEI. Because you duplicated the ROM it also saves the IMEI from that device to the other.
Additionally, most likely after the holidays, I’ll be uploading my firmware to this forum so you can use my backup, so keep an eye out for updates to this page. If you have any questions or concerns don’t hesitate to message me
