[OnePlus 10 Pro] beatbreakee:
No worries bro... as i stated in my reply, OP made a rather confusing conundrum out of the model numbers... they just have too many devices being crammed into the "2000" series... i just found a CPH 2421, and 2423 and those arent even OnePlus phones! Those jump right back to Oppo... But for the OP its understandable because the 10T Global is 2415... and i have found SEVERAL completely wrong fw identifications by a few "less english" speaking websites! But ive found em as well labeled wrong in the Oneplus Community pages, where the poster 1st called the

CHP2417

10T the "Chinese - Global Variant" 😲 then a few posts down he called the 2413 the "European - Global Variant" 🤨 ... That's a whole lot of Oneplus 10T "Global Variants" considering its 100% verified ==>

2415

Eu Global Variant

... but that guy was just posting as confident as if he had a 'PHD in Global Variantology' 🙃. So without someone who has literally torn apart the whole FW package, looking at everything inside as if i just broke a pinata, and all those files fell out, instead of candy... 👀 then it would be kinda ruckshot with identification of each. Every region wants the claim of "Global" because that fw will get the most 3rd party DL, and thus will have the most active development when it comes to feedback and making the mfg get to fixing whats broken. But seriously, i would not steer ANYONE in the wrong direction when it comes to stuff removed from stock fw.... 2213 and 2215 are almost identical, & you wont notice the difference unless you live in China. The ONLY extremely troubling thing i have found about ALL the 10 series, is that the T-Mobile variants ALL have hidden, undocumented, and never before heard of "Trip wires" in their builds! What i mean by never before heard of "Trip Wires", is: Processes, Actions, Flags, and Bin commands that a Google, Yahoo, Duck Duck Go, AND Bing search, yielded not 1 match for them! And when you type them into either an ADB shell, or directly in the terminal, they yield completely different error responses than a normal command that is wrong. ( "Function Undefined - Segment Variable Must Have "2" [Arg] ) <-- That one hurt my head!

I dont wanna dwell on it, cuz a few commands literally will disable a single antenna, or turn off your mic, and there isnt any commands that i fuzzed which would reverse the process, so accidently running them would require an MSM Flash to fix. But the "Trip Wires" are like traps set, just to brick your device. For instance, when flashing your BL to root your phone, on the T-Mo roms, ONLY A FEW are set up with an instruction that tells the phone to flip to the other slot on reboot. (Make sure to always have updated FB and ADB, along with tested magisk builds, cuz magisk should always install itself to the correct partition/flags when allowing the app to do the install! Manual flashing CAN accidentally break something! And google constantly changes variables or add new flags, which if your script calls for it, and it aint there, could cause a command to fail, but the script continues and your device reboots with a mangled flash... no good!) So when you're flashing to the inactive slot you let magisk do the work, after BOOTING a rooted boot.img. This is the CORRECT and safest way to go. But the 1st drop of TMO fw (11_A.03 on IN) literally has a control command set, for if the Aboot partition is accessed by any unsigned app, even if just to read or pull the file, then any reboot will auto flip BACK to the same slot, but it will allow the rest of the script to complete after booting. I really cant grasp that one, but it is kinda like the OS will grant system permissions to the script, but the commands will be sent at the stock files, so if they are system files, then it would brick your phone! Cant mess with system partition, really or secure boot & trust zone will stop the system from completing boot.... if I am correct then you would have PARTIALLY modified UN-PATCHED system files, and then a hard stop or panic when the secure boot fails... that is straight up malicious because they refuse to provide us an Unbrick option... yet they are making it happen to begin with. Bottom line is, that IF you get a T-Mobile model. and its working properly after modifying for Root.... Region... whatever.... 1st, go buy a lottery ticket... and then STOP making any changes to your file system, because TMO has an "Override_Developer_Mode_User_Opt" command embedded in the EFS file system, and for the life of me i could not find a reference as to what procedure can call it! But i do know that there are a few ppl incl myself who have met it in person! lol. The ones who have all know what im talking about... Every App on your phone gets locked, except settings... adb is removed from the "property:sys.usb.config=XX" function, and wireless adb is revoked.... all you can do is open settings, and stare at your phone when it rings... THAT is the command being called, when that happens, but it literally does not exist in ANY binary in the whole fw.

But TMO also uses "trick naming" schemes to place entire groups of command strings, and their arguments, pre-formatted inside system processes that you cant disable, or if stopped they auto re-enable themselves, or crash your device instantly. They even went as far as to alter the normal ussd dialer codes, and make a couple of them look as if they didnt work... but instead they actually signaled the phone to wipe the cache or initrd is instructed to force re-load a system file from a snapshot from hours earlier... i dunno, i just lost a lot of respect for tmobile, cuz if they are gonna go that far, either they have some nefarious plans coming in the near future for their devices, like some sort of Apple style encryption restricting all their devices... or some seriously ticked off programmers went rogue and set up all this crazy crap, then resigned & took the signing keys with them.. Whatever..... sorry for the long post.... i just really feel that when malicious intent is identified by a trusted carrier, someone needs to have it documented SOMEWHERE, so the next ME...YOU... WHOEVER steps up to the challenge, has a good set of notes on what has already been attempted, & what to avoid.

But if you arent using a TMO phone, then all youre missing is 6 bands that have 4 which are not even active in the US, and the other 2 are 3g here. Minus that, if you want Google services stay away from the 2211 fw, cuz you get "Heytapp" instead 😳 ... and if you ARE on a TMO phone, just be careful and follow every instruction with no deviation, only after several ppl confirm it to work! Rumors brick phones....Old methods brick phones... Brand new, single target successful methods brick phones that are barely different! Your 100% safest way to do ANYTHING with a TMO phone (only the 10 series so far) is to get your sim UNLOCKED , and bootloader UNLOCKED properly, before doing a cannonball off that cliff into the TMO ocean!
