Sorry to hear this !! But with no disrespect the term "developers" means - it's not for an average user nor for newbies!! U should hav done some research before using emma !! Always remember that you can get lots of help by going through articles or threads at xda -- by ur post i can see that device drivers r broken. so, i suggest u to install proper driver's for ur device and try using flashtool !!
-- Here u can find detailed guide --
As ur device drivers r broken - u should leave the device connected to pc wen flashtool asks u to connect by holding vol down until it recognizes. ( just be cautioned u should use ur device drivers only. The guide i mentioned above is for z4, u should download and install drivers for e5823!!)

Thank you for your critics =), ive tried this, the biggest problem is to connect the phone to pc, installing drivers dont do nothing, just simply flash tool dont see the phone becouse pc dont see the phone at all it dont pup up in device manager as unrecognised phone or other gadget, when you connect it to pc there nothing no any notification no nofing as you even didnt connect it, that the problem , if i could connect it from there i know what to do, still weard thing i don it many times but for this one absolutely dead phone never.

Drivers can be installed in 2 ways
1- through device (wen u connect ur device to pc, it wil automatically install drivers to pc)
2- by downloading device drivers from sonys dev site and installing them manually to ur pc
Since ur device is dead , it can't install drivers to ur pc which means u should install them manually by downloading from here
*** pls go through that guide! !Everything was clearly mentioned there. There r users who had recoverd their devices from hard bricks by flashtool!! Though it's long It can help u get ur device back to normal! stay away from test point stuff if u find any on google , it can short ur device permanently!! If u hav no time for al this and u hav already opened ur device - u can opt for a new motherboard @ <50 usd!!

It takes lot of time to recognize in this case. Btw u can try flashing ur device without battery!! Ur device can be recognized by flashtool even without battery (; just connect ur device without battery wen flashtool asks u to connect!

I was sure about what i hd mentioned in last reply ! I would like to know what happened in there other than motherboard damage!! As i can remember one of my fellow mates faced exactly this kinda experience and had successfully recovered by leaving the device whole nyt connected to pc in flashmode!! Wen he wokeup in morning he found that flashtool has flashed the ftf and informed to disconnect and start the device! ! Try this as a last resort Glad to help!! Tbh... U won't get any practical help by posting here!! They can just advice u to do some basic diagnosis which is not pretty much enuf!! gud day and gud luck
