Title: Need Firmware (KDZ) for LG E430 - Optimus L3 II
Body: Hi everyone, I’m looking for the original stock firmware (KDZ file) for my LG E430 (Optimus L3 II). The phone is stuck in a bootloop after a failed root attempt. I’ve tried the LG Mobile Support Tool, but it no longer recognizes the device properly.
Does anyone have a working download link for the V20a or V20b firmware for Europe/Open? I specifically need the E430 version (single SIM), not the E430g or dual-sim variants.
Also, what is the current best method to flash it? I recall using LG Flash Tool 2014 and putting the phone in Download Mode (Vol Up + Plug USB). Is that still valid for this legacy model?
Thanks in advance.

"Regarding the LG E430 firmware: This model (Optimus L3 II) originally shipped with Android 4.1.2. The firmware files come in .KDZ format. Be careful not to flash firmware meant for the E430g (a different variant). Most working stock ROMs are labeled V10a, V10b, V20a, or V20b depending on the region. Since LG removed old firmware from their servers, you'll need to find community backups. Avoid 'custom ROMs' for this device as they are often unstable or missing hardware drivers."
