oopsbagel d9688b1796 wingtech: install without disabling wifi
Previously, the unlocking method for the wingtech hotspot would add a
invalid mac address to the blocklist. This would prevent the wifi from
coming online after rebooting until the invalid mac was removed.

This commit changes the unlocking method to attempt to *remove* an
invalid mac, creating a no-op condition that still works for unlocking
root access to the hotspot.

This commit also adds documentation for a problem where the hotspot
would occasionally not reboot while completely disconnected and
installing over wifi.

Wingtech CT2MHS01

Supported in Rayhunter since version 0.4.0.

The Wingtech CT2MHS01 hotspot is a Qualcomm mdm9650-based device with a screen available for US$15-35. This device is often used as a base platform for white labeled versions like the T-Mobile TMOHS1. AT&T branded versions of the hotspot seem to be the most abundant.

Supported bands

There are likely variants of the device for all three ITU regions.

According to FCC ID 2APXW-CT2MHS01 Test Report No. I20N02441-RF-LTE, the ITU Region 2 American version of the device supports the following LTE bands:

Band Frequency
2 1900 MHz (PCS)
5 850 MHz (CLR)
12 700 MHz (LSMH)
14 700 MHz (USMH)
30 2300 MHz (WCS)
66 1700 MHz (E-AWS)

Note that Band 5 (850 MHz, CLR) is suitable for roaming in ITU regions 2 and 3.

Hardware

Wingtechs are abundant on ebay and can also be found on Amazon:

Installing

Connect to the Wingtech's network over wifi or usb tethering, then run the installer:

./installer wingtech --admin-password 12345678  # replace with your own password

Obtaining a shell

Even when Rayhunter is running, for security reasons the Wingtech will not have telnet or adb enabled during normal operation.

Use either command below to enable telnet or adb access:

./installer util wingtech-start-telnet --admin-password 12345678
telnet 192.168.1.1
./installer util wingtech-start-adb --admin-password 12345678
adb shell

Developing

The device has a framebuffer-driven screen at /dev/fb0 that behaves similarly to the Orbic RC400L, although the userspace program displaygui refreshes the screen significantly more often than on the Orbic. This causes the green line on the screen to subtly flicker and only be displayed during some frames. Subsequent work to fully control the display without removing the OEM interface is desired.

Rayhunter has been tested on:

WT_INNER_VERSION=SW_Q89323AA1_V057_M10_CRICKET_USR_MP
WT_PRODUCTION_VERSION=CT2MHS01_0.04.55
WT_HARDWARE_VERSION=89323_1_20

Troubleshooting

My hotspot won't turn on after rebooting when installing over WiFi

Reinsert the battery and turn the device back on, Rayhunter should be installed and running. Sometimes the Wingtech hotspot gets stuck off and ignores the power button after a reboot until the battery is reseated.

You do not need to run the installer again.

You'll likely see the following messages, where the installer is stuck at Testing rayhunter ... .
