Removing heavy system apps directly from the ZIP to save time and space post-flash.
Normally, when you sign a ZIP file (like a system update), the signature covers the entire archive. If you manually unzip it, swap out a single file (like a boot image or a script), and zip it back up, the signature becomes invalid. Your recovery environment (TWRP, OrangeFox, or Stock Recovery) will then reject the file with a "Signature Verification Failed" error.
If the original ZIP used a specific compression method (like "Store" or "Deflate"), using the wrong one during an update can lead to corruption. updatesignedzip usually handles this, but manual overrides can be tricky.
Check the file size; a successful injection should reflect the size difference of the swapped files. Common Pitfalls to Avoid
