Firmware extractor

Extract boot, init_boot, vbmeta and other partition images from a remote ROM ZIP without downloading the whole file.

Direct link to the ROM ZIP

A recovery/OTA package (.zip) on a server that supports range requests — for example Xiaomi’s official servers, GitHub Releases or most direct file hosts.

Partition to extract

Pick a preset or type the partition name (without .img).

Only the link is sent to this server; the partition is assembled in your browser.

Data comes straight from the firmware server to your browser. Data is relayed through this site (the firmware server does not allow direct browser access).

Partition extracted and verified Partition extracted — not verified

The image matches the hash recorded in the firmware package. The image matches the CRC32 checksum stored in the ZIP archive. CRC32 catches download errors; it is not a cryptographic hash. This package records no hash for this partition, so the image could not be checked. Compare the SHA-256 below with a source you trust before flashing.

How it works

Paste a direct link to a recovery ROM ZIP. The server reads only the archive index and the payload manifest with HTTP range requests; your browser then downloads just the bytes of the partition you chose, decompresses them (XZ, BZ2) and checks every block against the SHA-256 hashes inside the payload before saving the image.

Works with links that support range requests, such as Xiaomi's official servers, GitHub releases and most direct file hosts. Fastboot packages (.tgz) and incremental OTA files cannot be read this way.

Limits

Partitions up to 512 MB.
Fastboot packages (.tgz) cannot be read partially — use the recovery ZIP.
Incremental OTA packages are not supported (they need the previous firmware).
The image is built in your browser’s memory; use a desktop browser for large partitions.
