[GUIDE] Huawei usb 3g modem on android x86 4.4.2

[lemonsqueeze]

Finally found a way to get this usb 3g modem to work with android x86. Looks like there are significant differences in android kitkat, the other tutorials didn't work for me. Here's what i did in case somebody else finds it useful:

Model: Huawei E1752 HSPA USB Stick
Android x86 4.4.2 on Acer Netbook

Get modem to work under Ubuntu first so you have chat scripts that are known to work with your modem/provider. (If having trouble finding the right AT commands to initialize your modem you can record them under windows. Try free serial port monitor)

• Install PPP Widget. It doesn't work, but that gives us usb_modeswitch and pppd to play with.
  
• Install busybox if you don't have it already. Your device should be rooted.
  
• I disabled modem's cdrom mode so that i wouldn't have to modeswitch it with PPP Widget every time (did it from linux)

• Tweak and install pppd/chat scripts for your provider:
  
  /sdcard/pppwidget/ppp/free-chat
  Chat script to initiate connection. Change AT commands and dial number (*99#) if yours differ.

  ndc resolver setifdns ppp0 208.67.222.222 208.67.222.220
  ndc resolver setdefaultif ppp0

• To connect, open a terminal and type:
  
  

    $ su
    # cd /sdcard/3gmodem
    # ./connect

• Now you're connected. browser should work now.
  
• Connection is there but android doesn't know about it, so apps like play store which check connectivity will think you're offline. Install Fake Wifi Connection to deal with those.
  
• Done !

how to get chat script for other modem

 

[suect]

Hello, Can I use your chat script with Huawei E3531, and replace only the AT commands?
Do I need busybox?
I have no knowledge of commands, just very basic commands on android terminal.
I am having a really hard time to connect to internet, mainly because Broadcom BCM43142 wifi is not compatible with android 9.0-r2, and older versions.
Thank you
