      Hello,

      ZXW soft has a boardview for this model.
      Very low impedance on the center of coaxial connector is normal, it's not a short.

          Yes you are right sometimes the antena its like an wire loop to gnd. I already bought an ZWX competitor software and found where the wifi/bt ic is. thank you.

          is on back of the board ,near cameras hole and under a big shield.

              Help with trying to fix phone that is not charging (Pics inside)
              by SluggerB
              I have two TCL A30 phones.

              Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

              New Phone: Works fine, bought as a donor board to try and repair Old Phone

              My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

              Lift Master garage door opener with WiFi capability application through your phone
              by sam_sam_sam
              I had a lot of trouble with the WiFi connection from my router inside of the house into a ( new ) metal garage I had to run a 150 ft cat6 patch cord so the WIFI connection would be strong enough for the WiFi connection on the garage door opener would work correctly ( my son has a work out area in the garage as well and he was having to put his phone near the door to be able to stream music ) ( so I was going to eventually put WiFi out there anyway )

              This garage door opener WiFi is very touchy if you lose the power it does not remember the password for the router which is weird or...

              HP EliteBook 650 G10 No Wifi or Bluetooth after flashing bios
              by Dallen Bryce
              Hello all,

              I just finished flashing a new bios on an HP EliteBook 650 G10, and everything works except wifi and bluetooth. After installing the necessary drivers, the wireless card reports code 43 in windows. When restarting the computer, i get a code 10 (could not start) on the wireless card in device manager. I suspect that this could be a mac address issue, but I don't know what address to set it to in the bios, or if this is even related to the problem at all. Any insight on this would be appreciated.

              new OS on a Sonim XP5s phone
              by keeney123
              To you programmers out there I want to know if it is possible to put a new OS on the Sonim XP5s phone? I only need this phone to make calls, receive calls, have a list of contacts and be able to call voice mail.
              I bought this phone new Sep.2021 as an unlock phone from a third-party seller. The phone worked fine until Jan 2022. I then had intermittent problems with the sound setting resetting itself. One of the settings, outdoor, would go to silent all by itself. When in silent mode it does not indicate a call has come in. I missed very important phone calls. All the other setting in sound...
