You do not need Test Points to change boot loader. It can be now done via USB cable:

Hi, that is 100% right what I written in my post. The only problem is, that was my old post: 10th Dec 2012, 03:30 PM, that time we were NOT supporting this phone via USB and now we do.

but the phone it dead now after playing withe test point repair and not conected by usb and volume up and i have bay the atf nitro please it need to do this modification or no For ATF Nitro, you need some small modification to give Power to eMMC socket via RJ-45 PIN 2 (the pin beside VBATT PIN 1). Needless to say, if you modify your Nitro Box, you will loose warranty. So just decide for yourself if you need to modify or you want to buy external power supply instead. Anyway, here is modification needed, just look at light blue encircled area... you will see a very thin wire connected to PIN 2 of RJ-45.

thanks for help

Hi, Your box does not need any modification. Repair Boot to alive phone again, since it was stopped during Boot Change because of BAD SOLDERING.

Hi, JTAG requires to repair ALL Lumia Phones Boot via JTAG and ATF Software
repairs Boot via eMMC - both are different, lumia 710/ 800 does not requires
ATF JTAG. But for all the rest of lumia, JTAG is needed for JTAG Boot Repair.
