For Win8 phones, JTAG is more easier to solder.

But eMMC TP is Free.

Just make sure you match correct RM-XXX with phone...

@allumts

1. Connect JTAG wires to your 720, make sure USB Flex Cable is connected properly.

2. Download this
LUMIA_WP8_BOOT_CHECK - Download - 4shared

3. Use file in Step 2 with ATF JTAG... It will read info of phone and tell you exactly what it is...

Download the correct BIG BOOT File for it.

Hello, i've connected all wires and cheched 10 times for JTAG, but always "No Devices found in Chain", only change i've done in Jtag is n°7 BROWN, (for solder more easy cables have removed the plate and welded BROWN on point of this), but i think it's the ground and is the same....

@allumts:

Software log says, you did not do anything, just selected WP8 BOOT CHECK file.
You need to click on Read Info button after selecting the file and than connect phone on USB cable.

We re-checked wires solder on PCB, always same error with Lumia 925 dead phone. We just cant do it JTAG.

@ahmedrc25

Well it simply means you did not solder it correctly... and don't forget to remove BATTERY Flex Clip. Disconnect battery for JTAG to work properly.

Which devices driver must appear in pc when we connect usb cable to phone to make a jtag connection??

ahmedrc25 · 07-31-2014, 22:11

No driver see it. My question is: must see any detected driver in pc when we connect jtag to atf box and insert usb cable to phone??

ahmedrc25 · 07-31-2014, 22:13
