What you get for free. No time limit.
Flash iPhones — including MultiFlash
Restore or update one device, or up to 16 in parallel. The IPSW is downloaded directly from Apple. No credit is spent on flashing, ever.
On-screen diagnostic
Model, both IMEIs, serial, battery health and cycle count, component serial numbers (screen, camera, battery…) and a genuine-parts check.
Deep Check and IC Tester
NAND, Face ID calibration, battery cycles and parts history, plus a scan of 15 internal chips — without opening the phone.
Android flash, diagnostics and sanitization
Flash Samsung, Xiaomi, OPPO/Realme and generic fastboot devices. Read the hardware, wipe and verify, remove retail demo mode, reset FRP, issue a GDPR erasure certificate, and work on several devices at once.
The only thing that costs a credit. Everything in it is included.
Saving a report — 1 credit
The certificate with its verification code, the printable label or sticker, and the report kept in your online dashboard to export or share. One credit covers all of it.
You pay once per saved report — not per thing you print from it. Flashing, diagnostics, Deep Check and the IC Tester never cost a credit.
Three steps. That's all.
