B4 Pico Ultra Auto DFU Tool for iPhone XR, XS, 11, SE2 and iPad
Pickup available at Digilog Electronics
Usually ready in 2 hours
The B4 Pico Ultra is a one-click auto DFU tool for iPhone and iPad repair benches. Plug it into the phone's Lightning port, connect USB-C to your computer, and press START: it puts supported A12/A13 devices into DFU, DWN or Purple mode without the button-combination guesswork.
It is the upgraded version of the older B4 DFU box. The old box needed you to enter the mode with the B4 and then swap to a normal USB cable for the computer software. The Ultra does the whole job through one connection, so there is no cable swapping between steps. It is built on the RP2350A chip.
Key Features
- ⚡ One-click DFU mode - press START instead of timing button combinations by hand.
- 🔧 One-click DWN and Purple mode - enter the service modes needed for PWN/pwned DFU work on supported devices.
- 🔌 Single connection, no cable swap - Lightning to the phone, USB-C to the PC, and the whole procedure runs through that one link.
- 📟 Built-in DCSD - serial output for diagnostics on supported workflows, no separate DCSD cable.
- ✅ Status LEDs - DFU, OK and NG lights show the result at a glance; RESET button to retry.

Who It's For
Mobile repair technicians and iPhone service shops that put A12/A13 devices into DFU or service modes every day and want it done in one press. The B4 only handles mode entry; restore, diagnostics and other steps still need the matching computer software. Use it only on devices you own or are authorised to repair.
