Today I got Lumia 520 "ERROR : Unable to seek out a bootable possibility. press any key to shutdown". 
This American state common bother once upgrading WP eight.0 to 8.1, and this is often 
very simple to repair, by EasyJTAG
While different box did not find "ivalid blablabla", simple Jtag show the ability

Here's step by step however to: 
  

1.) Solder only 4 wire : CMD, CLK, DAT0, and GND



2.) Open Easyjtag Emmc tool, n connet usb directly to pcb as power of Vcc&vccq



3. Click Emmc Tool, set eMMC Voltage to : 3,3v
Detect eMMC card, you will see in log "Emmc Permanent Write Protection : YES"
This is the problem, just click on Advanced Opt, select "SAMSUNG : remove write protection" and execute by Custom Operation -->



4. Detect Emmc Card again to see the result, the trouble maker is remove Now , ..



5. Assemble phone, and flash normally with any box u have. 
And, just it, you just revive your phone back to live...
