I have done Lumia 900 unlock before, so my soldering seems ok.
But I keep getting error:

Resetting and Exploring JTAG chain...2 Device(s)
Device #1 ID 0x100590E1 IR7
Device #2 ID 0x203F10E1 IR4
Waiting for Device Connection 20 second(s)...OK

Disconnect all Flex cable connected on board.
Select unlock AFP file and click on Read Codes button
than connect USB cable to phone

@dannyogolo

Disconnect USB Cable
Disconnect Battery Flex Connector

Click "RESTORE BOOT" or "READ CODES"

Connect USB Cable

I have done what you both said, but problem remains:

The only flex on body is camera flex, as i had already disassembled the phone completely.

I observed that when everything is connected, the PC begins to slow down and get sluggish.
Could this have anything to do ?

Read Post #3 Carefully

As Instructed by me, click "REPAIR BOOT" first...

Count maybe upto 5 seconds, then connect USB Cable to Phone.

If you get error, then disconnect USB Cable, Click " REPAIR BOOT" then count 5 seconds, then connect USB Cable.

That is all you need to do.

If still fails, then it means your wires are TOO LONG.

For Lumia 520 problem, it means you did not connect the 2 ORANGE Wires correctly.
