Phone JIAYU G4S hard bricked -- SOLVED

[Aeonia]

I got EXACT the same problem - I was flashing at Friday and did the same combination:
- at first I flashed a rom
- then i flashed recovery

Symptoms are the same...
Have any one progressed with this ?

At last, problem solved. All the guys above where correct about the ROM version. Additionally there is a small bug in the flash tools caused all the mess. When trying to load a scatter file and finds it correct it loads all the *.img files. If you then try to load a different scatter file and it's not correct shows no warning and you have the impression that the flash tools load the ROM binaries. But it doesn't. The working ROM (find it in needrom.com) is the one as G4SL-20140422-120615-FL. But when you unzip the tarball the directory created contains chinese characters on the subdirectories names. So when trying to load it's relative scatter files flash tools refuses to load the scatter file as unrecognised. So copy the *.img and scatter file contained in pure english characters name (e.g tmp) and try to load the scatter file from there. For me it worked fine. So, thank you all guys contributed with all your advices and suggestions and good luck with your phone. Feel free to ask for an help.

glad to hear you managed to get your phone working again..
