 All OnePlus phones on the global market, and any Chinese models that were initially released with ColorOS 15 or older, can be easily unlocked using the [standard procedure](../../misc/generic-unlock.md). This includes devices that have since updated to ColorOS 16.0 or newer.

-According to the [OnePlus forum](https://bbs.oneplus.com/thread/1926504022886318086), for phones and tablets sold in mainland China, unlocking the bootloader is **only possible via an official application to join the “Deep Testing” program**.

+According to the [OnePlus forum](https://bbs.oneplus.com/thread/1926504022886318086), for phones and tablets sold in mainland China, unlocking the bootloader is **only possible via an official application to join the “Deep Testing” program** (also known as **“In-depth Test”**). After submitting a unlock request they normally take 2 days to be approved.
 **Main requirements:**  
 - Account must be in good standing (no violations or restrictions)  
 - No application submitted in the past 30 days  
 - Device is not a corporate or carrier-customized model  
 
-> **Note:** These restrictions currently apply only to devices sold in mainland China. However, due to the unified OPPO–OnePlus codebase, similar restrictions may be introduced for global models in the future.

+## Indian versions of OnePlus initially released with ColorOS 17 or newer (OnePlus 16 or newer)
+
+OxygenOS 17 is officially cancelled. Starting from OnePlus 16, there will be only two versions of OnePlus: Chinese and Indian. Every version of OnePlus 16 will be initially released with ColorOS 17. According to the same [post on bbs.oneplus.com](https://bbs.oneplus.com/thread/2175833961601695750), "Deep Testing" program will be needed on ANY device running ColorOS 16 or newer, regardless of model and version. However, Chinese KYC will be needed only on Chinese versions of OnePlus and it seems like, on Indian versions of OnePlus, you will be able to pass "Deep Testing" program with just global HeyTap account, which does not even require phone number for registration. However, other restrictions such as 7-day and 14-day waiting periods will still be needed.
 
-Even though OxygenOS 17 is officially cancelled (every version of OnePlus 16 will be initially released with ColorOS 17), "Deep Testing" program will be needed only on Chinese versions.
+## Devices upgraded to ColorOS 17 from OxygenOS (every version of OnePlus 11-15 except Chinese)
 
-Note that if you updated your OnePlus 11-15 to ColorOS 17 (when it will be released), you will be able to downgrade it to OxygenOS 16 through official Rollback package (note that it is not released yet). Note that it works even if the bootloader is not unlocked. Note that it works only on global versions of OnePlus. Note that after downgrading, you will not be able to flash any custom ROM based on android 16 other than that Rollback package, because this package has patched ARB index.
+These phones were initially released with OxygenOS. If any of these phones got upgraded to ColorOS 17, you can bypass "Deep Testing" program and unlock the bootloader completely offline by downgrading it to OxygenOS 16 through official Rollback package (note that it is not released yet). Note that after downgrading, you will not be able to flash any custom ROM based on android 16 (only android 17+), because this package has patched ARB index.
