Hello,
I have a Renault Clio 4 (2013) with Media Nav MN1 (LG LAN5210WR1).
Current details:
HW: 1.6.2
SW: 4.1.0
Windows CE 6.0
Unit is modified (iPhone Skin MOD 2.0.3 – previously unlocked for maps)
USB works
I have access to WinCE file system (Core Player / file browser)
Problem:
Bluetooth music (A2DP) works fine.
During phone calls:
The other person hears me
I cannot hear them (no audio output through speakers)
This happens with modern iPhone (latest iOS).
Toolbox does not work.
USB does not auto-generate update files.
System has custom firmware installed.
Goal:
I want to restore to clean stock firmware and then update safely to a stable version (6.0.3 → 9.1.3), without bricking the unit.
Questions:
What is the safest clean path from 4.1.0 (modified) to stock?
Do I need to downgrade to 4.0.6 first?
Is bootloader flashing required in my case?
Is there a confirmed clean 6.0.3 (MN1 LG Europe) package available?
Any known fix specifically for HFP audio output on MN1?
I am aware of brick risks and will follow proper procedure (engine running, correct FAT32 MBR USB, etc.).
Any guidance from people experienced with MN1 LG recovery is appreciated.
Thank you.
