Alcatel 9961 T-Mobile 4G CellSpot V1¶

Alcatel 9961 femtocell branded by T-Mobile. It supports UMTS and LTE.
Supported Bands: WCDMA B2, LTE B4.
Main SOC is Qualcomm FSM9950.
Power management: PMF9900
eMMC: THGBMBG5D1KBAIT 4GB
RAM: 4x H5TC4G63AFR-PBA
Ethernet switch: QCA8334
This device has tamper sensor. Looks like the tamper sensor is photodiode.
It is located on back side of PCB under power management IC.

To bypass this sensor covering it with black tape should be enough.

Under eMMC chip there are testpoints that may allow us to read and modify eMMC without desoldering it.

Network activity¶

All ports on WAN and LAN ethernet ports are closed.
After connecting device to network it tries to connect to ipsec tunnel initial-ipsecrouter.smallcell.t-mobile.com
IPsec CA certificate is:
