Hello,

I experimented with different bootloaders and had mixed results: I tried relocking the bootloader by flashing a stock boot.img and it didn't work. Decided to go ahead and finish rooting instead. I tried the 23000 magisk boot.img which allows the phone to boot but startup is much slower and the Wifi doesn't work. GPS looks like it's jammed 'on' based on the icon at the top of the screen. The 11.0.1.6 HD61CB has the same effect as the 23000 magisk file. Using either of these boot images causes the T-Mobile splash screen to randomly zoom in and out a few times during initial boot. I found 2 other stock boot images and they loop me back to the fastboot menu. I have the HD1925 McLaren. Suggestions on what I should do next? Do you need any more info that might help? I'm doing this via Linux because Windows adb/fastboot wasn't working for some reason.

Should I flash a stock McLaren ROM? If so, what's the best copy and what cmd should I use? Do I need to do some unpacking or compiling to the ROM file?

Also, when attempting to get a copy of the boot.img from TWRP (adb pull /boot.img), I received an "access denied" message. How do I circumvent that once my bootloader/ROM situation is stable?

This phone's a bit more stubborn compared to the Galaxy S4 I ROM'd many years ago lol.

Also, anyone have any luck getting ViPER Audio on their rooted McLaren?

Thanks in advance

The best way for your to get back to stock is to use the MSMdownload.
It will take you back to Android 10 then from there you can update it to the latest firmware.

Thanks for the input! I'll try doing this first. I figured that my only other option was push a ROM flash and hope for the best haha. Much appreciated!

I found a vanilla install of the OP drivers, installed them (doesn't seem like it appeared in the device manager but w/e) and used MSM Download tool 5.0.1.7 10.0.42 (note: when you download the 10.0.42 package from the XDA page, the file says MSM V4.0 when you extract the .zip file and open the extracted folder, but the program says 5.0.1.7 when you open it) follow these instructions on the YouTube video to boot into EDL mode and pay close attention: it seems like there's a short window of time to use MSM as indicated by the device connected/device disconnected sounds produced by my computer (10-15 second window)
. I did this and it worked exactly as it appeared in the YouTube video.

Also, Windows Update automatically found the Qualcomm L2 driver when I plugged in my phone. This may be due to the jankiness of my old laptop, but a few days (5 or 6) after the initial install of the Qualcomm drivers, Windows Update found another update for the drivers. Either A a new update was pushed or B it had trouble finding the latest driver for Qualcomm, something to keep in mind for those who had the same issues that I did.

Phone rebooted normally, can now find Wifi networks and connect to them, can turn off Wifi, Bluetooth, and NFC as desired, and is now updating to 11.0.1.5.HD61CB which includes the security patch upgraded to October 2021 and general improvements.

What a ride. Thanks all for your contributions to improving this phone!

Finally, I was able to find a working TWRP for HD1925 on android 11 even though it's only for booting. No more hassle on pulling boot image using payload dumper and python.

This make js042507 rooting guide 100% accurate and current. You can follow his instruction to the "T" and it will work perfectly.

I'm attaching the working TWRP file, original boot image and the patched boot image for Tmobile Oneplus 7T Pro 5G Mclaren HD1925 11.0.1.5HD61CB if anyone needs it.

You freakin' kick ass. Thanks! I hate that forums wind up being a "run on" over the course of a few years ... makes doing a simple smash and grab root & flash job an all-day marathon migraine (I actually never get headaches but I imagine this is a good analogy for those that do). Thanks for the succinct, meaningful, and poignant post which included attached files.

Yes/Maybe, to my knowlage you do need the stock boot.img or else update will fail, but you also need reserve.img
I can give you a stock boot.img from 11.0.1.4
However, best I can do for reserve.img is 11.0.1.5 which might not work I have no idea what if any information changed in it between .4 and .5

However the larger issue is if bootloader unlocking your device wiped out your reserve.img it also wiped out your persist and if that wasn't backed up in advance via MSM Readback you're kinda screwed there.
No one should give you their persist and you definitely shouldn't use one that isn't for your specific/unique device.

Hey, is there any chance you could upload the reserve.img from 11.0.1.5? Thanks in advance

Anyone else having trouble installing Magisk on the new update? 11.0.1.9, it might be due to the fact I had the manager hidden... All is working now though, HMU if you need a patched image

PS can anyone refresh my memory as to what I need to do to go from HD 11.0.1.3 rooted & bootloaded unlocked, to HD 11.0.1.9?

Do I just install the patched 11.0.1.9? My OTAs don't work.

    Hi. So I wanted to put together a little write-up on how to root the T-Mobile McLaren 5G variant, at least how I rooted mine, as there doesn't seem to be anything about this yet. I was actually able to root my device last night successfully, so I hope this guide helps others go through the process.

    **WARNING** Unlocking your bootloader will render your phone unable to take OTA updates! This is a newly discovered problem that hopefully will be fixed soon. But currently, unlocking the bootloader will wipe your data and also a reserve.img needed for the OTA updates. Proceed with caution!

    *I do not take ANY credit for this work. I am simply gathering data from various sources into one single reference guide*

    *Credit is due to HolyChickenGuy and dstryrwiz mostly, as I gathered most of the data from these members. Also, topjohnwu of course for Magisk.*

    So, anyhow, with this version of the OnePlus Pro 7T being carrier-locked, you must of course follow different procedures than a typical unlocked phone. And because OnePlus thinks they are special somehow, you also have to obtain an unlock code for the bootloader. :laugh:

    Steps that I followed:

    1. Obtain SIM unlock status via T-Mobile. In order to do this, I simply just asked a T-Mobile employee via Twitter if they could provide me a permanent unlock. And without any issues, they were very kind to do so....even after day 2 of owning the phone. And on the EIP, it's not paid off.

    2. After getting them to add your IMEI to the unlock list, go to the system settings --> WiFi & internet --> SIM & network section. There will be an option called "Network Unlock" at the very bottom under the 'Advanced' section. Click that and then go through the prompts. You want to choose "Permanent Unlock". Then, if T-Mobile made on their promise, it should ask to reboot...after which the 'OEM unlocking' option under the Developer Options will no longer be grayed out. Woohoo!

    3. After obtaining successful SIM unlock, now you have to submit a form to OnePlus to obtain the actual unlock.bin file to get the bootloader unlocked, generated from a unique 64 character code you will obtain in the next step.
    Ensure that USB Debugging is turned ON. In fact, make sure it's always on during this entire procedure, because it's required. Enter fastboot mode via holding the power and volume DOWN buttons during boot up. Or easiest way is to simply soft reboot with the "Advanced reboot" option enabled from the Developer Options. Once in fastboot mode, enter the following command to obtain this 64 character code...​
    fastboot oem get_unlock_code​
    This will spit out that 64 character code. Now go to this page, sign in, and fill out the form to submit for the .bin file.​
    NOTE: This takes at LEAST 7 days to get the .bin file. For whatever reason...it must be an automated system. I tried contacting them twice, but they wouldn't budge and told me I had to wait. LOL. And it seriously took EXACTLY 7 days and like 12 minutes for the email to arrive.​

    4. So after you have the "key" to finally unlock this darn phone, enter fastboot mode again and enter the following commands...
    fastboot flash cust-unlock "%path\to\unlock_code.bin%"​
    fastboot oem unlock​
    <<-- This step will ERASE everything on your phone. Most people know this, but I have to say it. Internal storage will be wiped too. :good:

    Finally, the phone is unlocked. Now we can root it.

    *I used various information from different forum postings...and some previous knowledge of course. Again, I don't take credit for any of this. I'm just following instructions. :cowboy:

    5. Download the unofficial TWRP .img file for the OnePlus 7T Pro from here. To be honest, I am not even sure if using TWRP for this part is really necessary, but somehow I came to that conclusion. LOL. This process worked for me, so yeah. Anyhow, enter fastboot mode again and boot to TWRP (do NOT flash it!) by entering the following...
    fastboot boot "%path\to\twrp-3.3.1-5-hotdog-unified-mauronofrio.img%"​
    Now in TWRP, enter the following commands to extract your stock boot.img file...
    adb shell dd if=/dev/block/bootdevice/by-name/boot of=boot.img​
    adb pull /boot.img​
    This will copy your boot.img file to wherever adb is running on your computer.

    6. Take that boot.img file and copy it over to your internal SD on your phone. Boot your phone up as normal, and go grab Magisk Manager from Git here. Open up Magisk Manager, expand the "Advanced Settings" option, and check the "Preserve force encryption" and "Preserve AVB 2.0/dm-verity". Select the "Install" button from the regular Magisk option and choose "Select and Patch a File ". Find your boot.img file and Magisk Manager will created a patched .img file. Copy this new .img file from your phone over to your PC.

    7. Enter fastboot mode again. Now just boot from this newly patched .img file by entering the following...
    fastboot boot "%path\to\magisk_patched.img%"​

    8. Final step. And hopefully your phone boots up.
    *If not, and you're stuck in a boot loop...you might need to make the A or B partition active. To do this, while back in fastboot mode, enter either command (most likely B)...
    fastboot --set-active=a​
    fastboot --set-active=b​
    Again, hopefully the phone just booted up normally without having to do that. Now in your phone, open up Magisk Manager again and simply choose the same Install option, but instead select "Direct Install". Magisk will now flash that .img file, ultimately granting permanent root privileges.
    Reboot and enjoy!! :D
