Base Band: M76XX-TSNCJOLYM-53404015
Compilation number: 2.1.1.A.0.6
I share it because I searched a lot in the web, with no luck. Furthermore, pc-companion or SEUS seems not to repair eclair anymore, unless you downgrade to baseband XXX006. Fortunately I found this post by shivenjuneja that helped me to restore my U20a eclair.
Why do you need this? Because if your phone is U20a and if you put some U20i ftf on it, you will lose 3g (edge will work). And of course, this is the fastest way to get a fresh stock eclair, in case you need.
Flash it with flashtool
