Free online tools for firmware work: extract partitions, find official ROMs, check an IMEI and get the right drivers.
Extract boot, init_boot, vbmeta and other partition images from a remote ROM ZIP without downloading the whole file.
Find official HyperOS and MIUI recovery and fastboot ROMs for Xiaomi, Redmi, POCO and Xiaomi Pad devices, with direct links to Xiaomi's servers.
Validate an IMEI, split it into TAC and serial, identify the model when the TAC is known and open Xiaomi's official verification pages.
Official USB drivers and platform tools you need before flashing, linked from their vendors.
The tools are free within fair-use limits. They never ask for account passwords and do not store the identifiers you enter.
If the phone still does not start, book a remote session and we will work on it with you.
