Upgrading JoinTech JE100 with JE200 firmware...!?!
We have known for some time that JoinThech JE100 and JE200 are so similar, except that JE100 has a limitation that it cannot read MicroSD beyond 2Gb. It is also well known that SDHC support can be implemented via software drivers. Thus, when I saw '_this post_' I decided to have a try on using this JE200 firmware on my JE100. It turn out that IT WORKS.
![]() However, since flashing of a new firmware is a risky business, you should be very careful and follow the instruction very strictly. You cannot blame me if you brick you beloved JE100, you have been warned! ![]() Have fun! |

What else are the differences?
(aka, is it worth doing, considering I never use a SDHC card with it...) |

You also get a new user interface package, which JoinTech named it as "jtos", and nothing more. If you use the JE100 as a winCE device (boot straight to windows & do everything from windows' menu/shortcut) and don't interest in the new UI, SDHC is the only gain from the upgrade.

Thanks a lot! It worked! Now I have a je200! The interface is much better and the device faster than before!

Yes, but does sleep mode still work? That was the problem with adding SDHC support before.

I wonder if the JE200 can be upgraded to the yet-to-be-released JWin700 and JAnd700 devices, as the specifications are exactly the same (other than a faster CPU)

That CPU could well be the reason it probably won't work... Most of these OS's are created for the CPU.
