For successful connection you need shorter wires, I look at your picture and the wires are too long... Make them 4 - 5 cm.. The shorter the better. Once you load D855 srf.. And your wires are shorter and you have connected the wires correctly... You can leave the setting to automatic... Medusa pro will automatically find the best settings and connect automatically. Also the D855... Has Medusa Pro USB solution... Did you try that? |

Also, as I see from your photo, eMMC wires are too long. For stable connection You need to solder each wire as short as possible (max. 3-5 CM length). Also here are a few main possible reasons why the device not connected: 1. You have connected battery or USB cable. Before connecting the device You must disconnect the battery and the USB cable, and then connect the device without power, this is important! 2. Some wires are soldered incorrectly. Carefully check soldering of all wires. 3. In the process of soldering, the resistors were burned (damaged) by using soldering iron or the pin pads on the board to which wires were soldered were damaged. Need replace damaged resistors and restore the pin pads on the board. 4. The ends of wires that were soldered, had not been cleared. Wire, that comes complete with Medusa Pro Box, is covered with an insulator, so before soldering need to clean the ends of each wire. 5. Soldered wires are too long. Make each wire as short as possible (3-5 CM length). 6. For GND connection use more thicker wire. Check all of them and try to connect the device again. | |||

Member: 1538383 Status: Offline Sonork: 100.1587278 Thanks Meter: 3,395 | Please check all possible reasons 1-6 again and try to connect the device again. Most likely, the problem is with connection. Also, You can try to connect this device via USB and then try to make Factory Repair using the latest original LG firmware for this phone model. To repair the device, do the following: 1. Install the latest Medusa Pro Software version (Medusa Box Downloads - Software, Drivers, Manual). 2. Download and install SRF (Smart Repair File) for D855 (for USB repairing) from the Support Area (via "Download *.srf" button in Software). 3. Select "USB" option in Software. 4. Select LG D855 in the Software list (model will appear in Software list after SRF installation). 5. Connect the phone in "Qualcomm...9008" Mode to PC. If necessary, use Test Point ("Test Point" or "Help" button) and install driver. 6. Press "Connect" button in Software. 7. When device will be connected successfully, make Factory Repair using the latest available original LG firmware for this device ("Factory repair" tab in Software). 8. Post here the result. The latest original LG firmware You can find or request in here: http://forum.gsmhosting.com/vbb/f664...y-mod-2192515/.
