Frequently Asked Questions
Find answers to common questions about firmware downloads, cloud tool rentals, remote unlocking procedures, and wallet payments.
What is a 4-file or 5-file Samsung repair binary?
A 4-file repair binary contains AP (System partition), BL (Bootloader), CP (Modem/Baseband), and CSC (Carrier Specific Customization). Flashing all 4 files completely re-partitions corrupt internal memory and unbricks devices stuck in bootloop.
Are all firmware files tested and safe from malware?
Yes. Every package uploaded to our library is verified by hardware engineers and checksum-authenticated before publishing. Download links are mirrored on high-speed global CDN nodes.
How does tool rental work without physical dongles?
Upon order completion, our automated credential dispatcher assigns active server login credentials to your dashboard. You simply open the official software (e.g. UnlockTool) and log in with the assigned session credentials.
What is required on my PC for a remote unlock appointment?
You only need a Windows PC with an active internet connection, official USB drivers installed, and our encrypted USB Redirector client. You can chat live with the technician on your order status page.
How does the 100% Escrow Wallet Refund Guarantee work?
When placing an order, funds are safely held in escrow. If an unlock operation cannot be completed due to hardware failure or unsupported firmware, the technician closes the order as refunded and your wallet is automatically credited instantly.
