Hello.

Repairing of LG H440n is currently not supported, but supported repairing of LG H443 via eMMC. You can check, whether PCB and eMMC pinout of H443 are the same (or similar) as PCB and eMMC pinout of LG H440n and if they are the same (or similar), try to connect your H440n as H443 and then do "Factory Repair" using the latest original LG firmware for H440n.

To repair phone via eMMC, try to 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 H443 (for repairing via eMMC) via "Download *.srf" button in Software.
3. Select "eMMC" interface option in Software.
4. Select LG H443 in Software list (model will appear in Software list after SFR installation).
5. Press "Pinout" button to look at H443 eMMC pinout picture and check, whether PCB of H443 is the same as in H440n. If they are the same - solder all necessary eMMC wires accordingly to the pinout picture.
6. Connect the device to Medusa Pro Box and press "Connect" button.
7. When device will be connected successfully, do "Factory Repair" ("Factory repair" tab in Software) using the latest original LG firmware for H440n (in "*.tot" or "*.kdz" format).
8. Disconnect the phone and try to put it into Download Mode.
9. Post here the result.
