Help VN007 5G MODEM FIRMWARE FLASHING VIA ONBOARD SERIAL CONSOLE UART USB TO TTL

[Joefil]

Hi po, sana po may makapag guide sakin paano mainstall ang firmware ni vn007 via onboard serial console. Di ko na po kasi ma access ang webui ng vn007 ko parang nagglitch ata during process of downgrading. Ang function nalang ng vn007 ko is as an Access Point nalng though nakikita ko parin ssid niya pero other than that wala na akong ibang maisip na para para mareinstall ulit ang firmware. Sana meron may alam at makagiide sakin. Meron na po akong usb to ttl at miniprogrammer pero di ko po alam pano gamitin

Seems i am able to fix this. i am having same problem. I could connect to Vn007 using UART and i can see details inluding tftp server and exact name of file router is looking for. However, i need to sort

1. Which image to use to flash (not sure if i can use firmware available online directly? 4 X21G_IDU_1.10.10_usr_UN2020C_20210918_1.8.5_update.pac just by simple rename)

2. I know exact steps to flash. However, i need to reconfirm Load address and memory start.

If i get any pointer on above for VN007, all sorted ..
