- Erase: Wipe specific partitions (like Modem or Persist) without a full factory flash.

Real Life Example: Saving the Day with v1.7.2
Imagine a customer walks into your shop with a brand-new ZTE Axon 60 (hypothetical model running the new SM8750-AB chipset). They bought it second-hand, and it is locked with a Google FRP screen. They have proof of purchase, but they can't remember the previous owner's account.
The Old Way:
You try your old box tool. It connects, but it says "CPU Unknown." You try a generic EDL method, but the firehose loader fails because the protocol for the SM8750-AB 8E is slightly different from older chips. You have to tell the customer, "Come back in two weeks when other tools update."
The FRT v1.7.2 Way:
You launch the updated FRT Tool. You select the "ZTE" brand and choose the newly added SM8750-AB support. You put the phone into EDL mode.
- The tool recognizes the CPU immediately.
- You navigate to the Reset Options and select FRP Reset.
- FRT communicates with the firehose loader, bypasses the security check, and wipes the FRP data.
- The phone reboots straight to the setup screen.
You just completed a repair in 5 minutes that other tools couldn't touch.
