These firmware can use for Update / Downgrade firmware your OnePlus 2 , Unbrick OnePlus 2, restore OnePlus 2 to 100% stock official, repair OnePlus 2 using fastboot, e.g : OnePlus 2 bootloops “Stuck on logo” or softbrick, OnePlus 2 black screen and can not open recovery mode or Hard brick.
As OnePlus don’t currently provide download links for their older Oxygen OS ROMs & OTA update zips, I’ve mirrored them all on AndroidFileHost and put the links in one post so that they’re easy to find.
There are two types of file for each ROM: signed flashable zips and OTA incremental update zips.
Signed flashable zips: These are recovery-flashable zips of the full ROM that won’t overwrite your data partition. They can be flashed via stock or TWRP recovery.
OTA incremental update zips: These are recovery-flashable zips that update your rom to a newer version. They can be flashed via stock or TWRP recovery but will only work on non-rooted devices with no modifications to system files.
I’ve also included links to the latest TWRP custom recovery and SuperSU.
Note: Since OTA incremental update zips will fail on rooted devices or devices with modifications to system files, it’s not possible to use these to update without reverting back to completely stock, unrooted first.
To update you must either wait for the new, full, signed flashable zip to appear (usually a few weeks after the OTA update) or use the following workaround:
Boot into TWRP recovery
Flash the latest full signed flashable zip
Flash the new OTA incremental update zip
Flash the SuperSU zip
The result is exactly the same as if you’d flashed the new, full rom zip.
