Hi mate

First, I can confirm your experiences. I also had several J6 phones that didn`t turn on. I flashed them with all flash files that I have but nothing helped. I am sure, there is a serious factory defect with these phones. The interesting fact is, they are all easily flashed without any rejection.

Second, if you want service manuals go to landy`s page. There you will find necessary service manuals (thanks him).

Good Luck

I never met this problem, but only my thight- You write 000000... occure after charging, may be there is foulty in power supply (if eepr is external it can be not powered, like sumsung work without eeprom). Did You try to bring one phone to sony service sentre and after their work find out what they change....? (but they can replace whole phone...)
Thanks

In my country there is no Sony Service Centre, therefore, I can`t

do what you suggest. But in any case, I think they would easily

change the PCB and solve the problem. I will look in service

manual for eeprom, if any, I will post here.


I think we should discuss these problems of Jx series with more

experienced people, therefore, mods, freaks and no life posters

are also invited.

The main problem is all the chips on the Jx board are without legs. Therefore, I am afraid of making experiments with such boards.
