To anyone thinking of flashing the international firmware onto a TMO model -- don't. T-Mobile uses a unique RSA cert to sign their firmware. The hash for that certificate is stored in the CPU .. and if you flash firmware that was signed with a different certificate you end up in 9008 QDL mode, and no way to fix it.

[OnePlus 6T  Guides, News, & Discussion] djkinetic:
U mean not to flash otas and critical?? Full rom imgs have proven to work..my only concern is if critical is updated by OnePlus in the future and they make it mandatory to have a certain version of critical in order to boot new firmware. In which case then tmo users are stuck till tmo itself issues updates.
[OnePlus 6T  Guides, News, & Discussion] Addiso:
Just when I was going to dm you and see if you can look into it. Thanks for the support in the v30 threads! Hope you can find your way here and stick to oneplus.
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
If by critical you mean, the bootloader, modem firmware, trust zone, etc.... yes, those are the ones that are RSA signed.

If someone wants to dump xbl_a from both the TMO and international versions, I will be glad to double check .. maybe TMO had a change of heart with the OP6t.

FYI - I don't own the phone, just trying to help people keep from bricking their devices.

We have a dump of each the tmo and international one in the following thread

https://xdaforums.com/oneplus-6t/how-to/rom-stock-fastboot-roms-oneplus-6t-t3862516

Although I'm sure it's easier for me to dump you the xbl_a only but I'm away from a computer at this moment.
[OnePlus 6T  Guides, News, & Discussion] jerrywmilton:
You might wanna clarify what you mean by FLASH. there is a whole thread of folks that have flashed 9.0.5 just fine. I assume you mean using the MSMtool or screwing with critical.
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
Yea, I was really hoping I didn't have to download two full dumps -- although I will. :)

-- Brian
[OnePlus 6T  Guides, News, & Discussion] Addiso:
As far as I'm aware. In the v30 there was certain partitions that could be flashed without a brick and some partitions that were signed (TMO signs their own with a different RSA cert), so in result it could potentially be that the tmo oneplus 6t is the same way and tmobile signed some partitions that can't be flashed.
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
If all you are doing is flashing the system image -- you are fine. The firmware which is RSA signed is what will bite you.

Up till now, those familiar with OnePlus haven't had an issue since OP used the same RSA cert to sign all of their firmware. Now that their is a TMO version, it *probably* is signed with the TMO RSA cert -- that is the way TMO does with all their other phones. For example the H918 TMO LG V20 can not use the firmware from any other LG V20. Again, they *might* have made an exception this time, and it is real easy to tell with a dump of xbl from each.

[OnePlus 6T  Guides, News, & Discussion] hartleyshc:

[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
Is that from the international or TMO version?

EDIT: I have downloaded the full 9.0.5 dump that was linked to for the international, so what I need is xbl or abl from TMO now.

-- Brian
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
TMO

I did a dump of every partition, except data, the second I unlocked my bootloader.
[OnePlus 6T  Guides, News, & Discussion] runningnak3d:
Well, it isn't RSA signing that is bricking the TMO version -- the certs are identical. What is interesting is this:

1423:d=5 hl=2 l= 3 prim: OBJECT :organizationalUnitName
1428:d=5 hl=2 l= 42 prim: PRINTABLESTRING :General Use Test Key (for testing 13 only)

The question is, is that the Google test cert? If so, you guys lucked out and can sign your own firmware.

Sorry I can't explain the bricks, but it is most definitely not due to different RSA signatures.

[OnePlus 6T  Guides, News, & Discussion] onliner:
I think I have a BIG problem, I installed the latest Q DP, rebooted, and my phone was stuck at the bootloader unlocked warning, I can't boot twrp/fastboot because I can't pass that screen, I rebooted to EDL to flash OOS Pie with this tool but "waiting for device", I tried with the two drivers in the OP but no luck.

Edit: Fixed! The phone just rebooted by itself, I manually rebooted to EDL again and the tool is flashing the system now, this phone will drive me crazy someday.
[OnePlus 6T  Guides, News, & Discussion] majikfox:
I guess you have to run this twice

This phone has been a massive PITA when it comes to flashing custom ROMs.

Anyway, after I flashed the phone with this tool and then switch slots form A to B it still had the old ROM in slot B.

So I guess you have to do something like this:

. Run this tool on slot A.

. Boot into the OS and enable OEM unlocking.

. OEM unlock.

. Install TWRP.

. Use TWRP to switch active slot to B.

. Run this tool again.

. Boot into OS again

. Enable OEM unlocking again

. OEM unlock again.

every time that use this tool my op6t from tmobile boot with McLaren logo is this normal? read every thread here or i try to change bootanimation.zip but nothing works

i used the 6T MsmDownloadTool v4.0.58 (OOS v9.0.11)
[OnePlus 6T  Guides, News, & Discussion] :
Dunno If this will help but there is a thread in the Guides Section, (Convert OP6T International into McLaren Edition). Using that changed the Bootlogo into McLaren Edition. However when returning to Stock OOS people still had the McLaren Bootlogo. The solution was something like "fastboot erase logo" or something. I'd definitely read through that thread. Maybe it's the same.
[OnePlus 6T  Guides, News, & Discussion] Mervingio:

using t-mobile version of 6t, just got today.

tried to run, got errno 31. i've tried many different things, going as far as factory resetting the phone, still got errno 31.

i'm using the t-mobile patched exe files, and i do get different results when trying the 2:

running the normal MsmDownloadTool V4.0_factory_patched gives errno 31 when installing reserves2.bin

running MsmDownloadTool V4.0_factory_mcl_op1_patched gives errno 31 when installing system.img

running either one of the non-patched executables gives me errno 31 when installing system.img

the phone boots completely fine after these errors, implying it does no sort of patching at all.

i've installed the driver, enabled USB debugging and connected the phone prior, held down the volume buttons when connecting for flashing, etc. etc. and no matter what i do it does not work. using latest version of the program (OOS 9.0.13) and my device has OOS 9.0.13.

If your OnePlus 6T from T-Mobile is brand new, are you following this guide (since your phone is still sim locked):

https://xdaforums.com/showthread.php?p=79344745

Otherwise, your device needs to be paid off, you need to keep it on TMobile for 40 days before you can have it sim unlocked, and then you can use an easier method to unlock the bootloader and install the international version.

[OnePlus 6T  Guides, News, & Discussion] Gimdaphone:
I've been trying for the whole day yesterday with my one plus 6T

just so you know the details it started in edl mode after I installed blu spark, then after a reset it went off and stuck in a "QUALCOMM crashdump mode" with a message error "Attempted to kill init! exitcode=0x0000000b do_exit"

I've tried the usual technique, updating the right drivers, the phone shows up as "qualcomm HS-USB diagnostic 900E", and the whole screen in MSM shows empty, i've tried manually changing the driver to QLoader but it doesn't do anything so far.

I've tried several MSM versions just in case, and reloaded different drivers

Is there something I'm missing ? Please do advice me
[OnePlus 6T  Guides, News, & Discussion] :
Is the phone screen Completely Off? As in Black or it has the Crash Dump Logo? Also you can exit Crash Dump by Pressing and Holding Power and Volume Up for a few seconds

[OnePlus 6T  Guides, News, & Discussion] Gimdaphone:
The phone screen still opens, with the one plus logo, followed by the warning because the phone boot loader is unlocked and then the crash dump mode follows and it's pretty much all. (at this exact moment, I can still see the usb in my device manager, as QUALCOMM diagnostic 900E. Pressing up and power completly shut off the phone and at this point it's a blank screen and it's not recognized by the computer.
[OnePlus 6T  Guides, News, & Discussion] :
So you need to Power of your phone. Power and Volume Up should do the Trick. Once screen is black, press and hold BOTH VOLUME BUTTONS and plug phone into PC. Then Run MSM Download Tool
[OnePlus 6T  Guides, News, & Discussion] Gimdaphone:
Alright, I went back to the basics probably like 20 times more, tried to spot any mistake and at some point it did work. I went into that blank screen yet still connected to the computer and from there I knew how to finish.

If I had to guess, I think it was a combinaison of a faulty cable and me not pressing correctly the buttons.

Thank you :) The questions you asked led me to go back to the basics to avoid any mistake from there. cheers

Bricked 6T

I've tried all versions of the MSM tool and this is what I get.

I got here by flashing cr Droid rom but I had the wrong Gapps. It was late so I powered down with TWRP thinking I could just boot back into recovery in the morning with the right Gapps. I can get into fastboot but when I try enter recovery it just goes to a black screen.

Hi to everyone! I need your help this is my situation:

I wanted to switch from stable path to beta path, my phone is unlocked, with twrp and root with magisk.

[UPDATE]

I read, again, the funk wizard's post and only now i realized instead of remove also my magisk modules I remove only Magisk... like a real idiot. and this explains why I could not flash the temporary reovery

I followed the steps posted by Funk Wizard but I made a F**ing mistake! after a full wipe I've chosen "reboot recovery" instead of copy the Rom's file and now I'm stuck Fastboot mode.

When I try to boot twrp this message pop up:

Sending 'boot.img' (31136 KB) OKAY [ 0.953s]
Booting FAILED (remote: 'Failed to load/authenticate boot image: Load Error')

My questions are: how can I do? I've accidentally bricked my OP? there is a way to use this tool with adb and fastboot? I'm a mac user and I don't have a windows pc.

[update - solved]

Thank You but I've already tried and didn't work, in the end I found a very helpfull post by mauronofrio and I flashed manually the entire rom. So far, so good.

The problem being with the first boot, when I tried to download an apk the phone said something about the sd card like if there isn't, so i back to recovery wipe internal storage and solved also this problem. But, again, when I reboot the phone is like if it does a soft wipe itself: I've to choose my Google Account to do backup data, nova launcher, whatsapp, telegram...etc restart with their configuration.

Any idea?

[UPDATE - SOLVED]

I format data instead of wipe! I don't know why but in my brain wipe and format it was the same... but indeed I don't know how many times I've done!
[OnePlus 6T  Guides, News, & Discussion] Nosferatu.:
I must say how grateful I am that this exists. Long story short I had some random freezes and glitches on the phone. I tried everything to get it to stop doing such (reflash TWRP, reflash ROMs, format internal data, etc.). None of these would fully fix the problem. You'd think wiping the system and data partition (internal storage) and installing the factory ROM would fix an issue. Nope! MSMTool a resounding YES it's fixed. I'm debating staying unrooted for a bit. Other than adblocking (Blokada, DNS editing, Adguard, etc seem to do the trick) and Titanium Backup I'm good without. Android 10 brings themes back and Viper4Android is nice but not essential means I'll enjoy stock again for a bit. :)
[OnePlus 6T  Guides, News, & Discussion] badpanda:
Apparently this TMobile to international conversion is not a 100% full fledge one... As demonstrated yesterday with Android 10 Beta 1 release, it bricks the device completely with yellow letter at boot up saying there is a mismatch and turn off.. when trying just to do a simple local update to the new Android 10 Beta.

So please save yourself time and aggravation and don't try to install the newest Android 10 Beta on this conversion as it will not work, brick your device and you will lose everything.

Hello all!

I've been playing with custom roms and I have eventually bricked the phone. This is the first time I flashed the 6t with this PC and forgot to install the drivers and I spent hours trying to find a solution why fastboot commands are not working. My phone was shortly bricked and messed up.

Current situation: Phone dead, bootloop, locked bootloader, no twrp.

I remember flashing persist.img which miraculously worked which hard bricked device.

MSM doesn't seem to flash persist partition and so it doesn't fix the phone.

So shortly my question is: Is there a way to unlock bootloader on dead phone so I can flash stock persist.img file

I've been looking for solution on thousands of forums and still no luck.

Thank you dear developers!

[OnePlus 6T  Guides, News, & Discussion] sscsps:
Just hold vol up button and power button together to get into edm mode, and then you can use MSM tool,

There is no indication on phone that you are in edm mode, except a vibration when you get into it. Thebscreen remains black and it seems like the device is still off. But connect the phone to pc once you feel that vibration and pc should detect a device, try this tool then.

Coming from Android 10 doesn't matter, edm doesn't change.

You might need to check device manager on your system to verify the drivers are working fine
