[OnePlus 10 Pro] beatbreakee:
!!! This is a HIGH RISK method of performing any form of modification, if you are on a T-Mobile ne2217 !!!

There are unidentified files that your device might have conflict with, and cause a bootloop!

Proceed at your own risk! You have been warned!​

OK, first lemme explain. The NE2217 (10 pro) itself does not have any special restrictions on it, unlike the CPH 2419 (10T) which is an exclusive T-Mobile variant. My guide on region swapping the CPH2419 (10T, link below) is still valid for the NE2217 (US- NA) . But there are conditions required or you will enter an infinite bootloop which becomes un-recoverable, without an edl flash. I do not have the specifics as to exactly which partitions cause this, but basically the bottom line is, IF YOU HAVE NOT UNLOCKED YOUR BOOTLOADER, EVEN IF YOU ARE SIM UNLOCKED, do not attempt to region swap.

There are a couple of partitions that are specially locked, that ONLY become write capable using the fastboot command, "Unlock Critical". Without a Bootloader unlock, the Oxygen Updater/Local Update programs, CANNOT make the needed changes to the Kernel, as well as these other important partitions, which have instructions that implicitly block changing to other regions. I cannot confirm if this exists in other countries with carrier locks, but i do know for a fact that T-Mobile has this enforced on all of the 10 Pro (ne2217) purchased through them.

As mentioned in previous threads that ive replied in, I suspected that the apps Oxygen Updater and Local Update, do not have the permissions capable to make direct changes to the boot.img, or recovery.img directly, primarily because those partitons cannot be altered while the system is currently running. These images can only be altered through Fastboot, or EDL thus the need for an MSM Tool if you cannot unlock your bootloader via conventional methods. So what happens is upon "Pre-boot" those special instructions i spoke of, take authority and put the carrier specific files, into an untouchable state that are locked behind the USERDATA partition, so these applications just copy the updated files to the inactive partition and performs the changes during the next boot, and even a hard wipe factory reset does not have the authority to erase the carrier instructions. The only way they are removed is by Unlocking your Bootloader! When you do that, the Qualcomm Processor has an embedded command, which is required to ERASE the entire Userdata partition, to protect the encrypted files protected by the bootloader lock! You can read about that by googling "Qualcomm Bootloader Unlocking".

Hope that makes sense to the majority of you. So again, the ONLY requirement for you to be able to go from 'ne2217', to any other fw is YOUR BOOTLOADER MUST BE UNLOCKED!

Failure to follow that one requirement will indeed force your device into an unusable, infinite bootloop, which can be resolved only by an EDL flash, which as of right now we do not have the tools that can perform this on CONSUMER level. You will have to RMA, your device, or go thru third party channels, which in itself is very risky, and puts you at risk of viruses/malware/wormholes/zombie-apocalypse because you must give someone full access to your computer remotely, and pray that the person only does what you requested. (NOT IDEAL).

Now if you're on a T-Mobile locked device, you are NOT hopeless... as I am on a T-Mobile locked device, and i am now bootloader unlocked as well! These two conditions are independent of each other, but trust me when i tell you that YOU DO NOT WANT TO GO THRU WHAT I HAVE EXPERIENCED, IN ORDER TO REACH THIS GOAL!

In so I will not publicly disclose how i was able to enter the real Fastboot Mode, so that i could pull the unlock code needed to request the unlock token from T-mobile.

(If you are so inclined to do this that you are willing to forgo ALL precautions and risk the possibility of bricking your device, or you have already landed yourself in an unrecoverable bootloop state, and are willing to try ANYTHING, you can join Bootloopers Anonymous, by clickiing it, and drop a message. This is a brand new telegram channel, and i will try to watch it for your requests. And again i strongly advise that you DO NOT embark on MY adventure, but if Unlocked Bootloader by Any Means Necessary is your ultimate goal, and nothing less is acceptable, i will try to help you achieve it... *** YOUR DEVICE WILL ENTER A COMPLETELY UNUSABLE STATE FOR A MINIMUM OF 7 DAYS!! *** but bear in mind that EVEN IF you have to use my method, you will be still subject to the 7-day waiting period outlined by OnePlus company policy. No one can overcome that, as the unlock token comes thru a separate division of Oppo/Oneplus that only generates the token through an automated request which is pushed after the expiration of 7 full days (1-week) has passed. YOU HAVE BEEN WARNED!)

The 10-Pro doesn't require the "In-Depth Testing" app to get your BL unlocked. That said, it also does not mean that OPPO has not designed one for this device because indeed they have. That application is individually encoded with device specifications so that only devices and regions EXPRESSLY AUTHORIZED by Oppo, can submit a request to unlock. DO NOT TRY sideloading any "In Depth Testing" apk floating around on the internet, as these can be altered to contain malware or worse, and then if your device becomes corrupted by it, Oppo can deny you an RMA on your device, thus charging you for the repair as there are warnings that you must acknowledge to even run the app, and attempting to circumvent the safeguards that this app already has in place is considered a violation of ToS.

If OPPO adds your device/region to the list of allowed devices, you will be able to download this application through OFFICIAL channels, and it will be made known to the public.

Once you are completely knowledgeable that your BL has indeed been fully unlocked, you can proceed to follow the instructions in the link to my guide below. The guide is for the CPH2419 (10T), but the instructions are completely compatible with the 10 Pro entire series, assuming your BL is unlocked. On the 10T this is not a requirement, and i honestly do not understand why this enforcement was put into our 10 Pro model, released almost a year earlier. Probably just an oversight by T-Mobile which might be corrected in future builds.
