problem wifi R90 RK3229 Please help

[delbiro]

Hello

I installed a ROM for R90, but it did not work because of the difference in the boot, so I opened the cover to enter the Mask rom mode and toch between Pin 7 & 8 and I actually succeeded in reinstalling another ROM, but when I opened the cover, the Wi-Fi wire was automatically cut off due to poor welding quality, After installing the ROM, the WiFi did not work, I tried to install it with my finger in the same place where it was soldered, but it did not work, I want to help guide me on how to install the wires with the correct place

NOTE : i check this rom update-0112-8.1atv-leelbox-done before open cover its work wifi but after cut off not work

Wifi : sv6051p chip

Board : rk3229 _mxq_5g_bt v1.0

please help

Observations From images posted

Image with red arrow pointed at Red Circle

Solder the outer Braided Shield there

Solder the inner core/single conductor to Solder Blob left of Red Circle

Probs best to remove both solder blobs and expose /clean pins/contacts

Good Luck

Happy Testing
