Did you install the global version first? I don't think that room will work for TMobile ROM

Yes I tried the global room first and it gets stuck on the boot screen. The RomAur room will boot and get all the way to the wifi selection screen then reboot back to twrp

Normally what I do if something like that happens is erase the entire operating system install TWRP then flash OxygenOS via USB flash drive in both slots.

I downloaded the 9.5.4 fastboot zip extracted it then put the phone on fastboot mode. Install the twrp.img Format all data then go back into fastboot mode. Then in the extracted zip find the flash all-partitions and click it, let it do it's thing. Once that's done it may reboot and get hung up on the boot screen. Just go back to fastboot mode and flash "flash-system-boot-vender". Once it's done It may reboot again and get stuck on the boot screen. Go back into fastboot mode then flash the twrp.img and get into twrp, there you should be able to flash the twrp.zip if not you may have to adb sideload it. After that it should boot up into the international ROM. If you can't get WiFi to show up youll have to flash the sky dragon kernal.
you can find the fastboot zips here https://androidfilehost.com/?w=files&flid=294300
*You do this at your own risk*
Don't blame me if you screw something up. If I screwed it up I would've simply took it back to tmo for a new one

[SOLVED] TWRP not flashing - "Too many links"

When I try to flash TWRP, I'm getting the error "Too many links." I am flashing in download mode, trying to flash TWRP 3.1.1-1. I am currently in the latest firmware for Sprint.

Is Sprint U11 unlocked?
Are you using command: fastboot boot twrp.img ?

Yes, bootloader unlocked. I flashed the latest firmware (which, of course, overwrites the recovery), and I am using fastboot flash recovery twrp3111u11.img.

Try renaming to just twrp.img.
To boot TWRP, fastboot boot twrp.img - done in Bootloader mode
To install TWRP, fastboot flash recovery twrp.img - done in Download mode.
For both U11 and Pixel 2XL, I only boot it and don't install it.
You could try that if above install command no worky.

Umm....you do realize that I renamed the file? I use my own file-naming scheme to keep track of the TWRP images on my PC, named by TWRP version and product name.
I pass on some of my phones to family members, and I keep all of the latest TWRP files, with the exception of the Evo 4G LTE....that one had 2 different system partition setups, depending on the firmware version. I need two versions of TWRP for that one.

oh ok.
So I got my problem solved. Turns out that my driver's needed to be updated when I updated the firmware. Don't ask me why, but that seems to be the case. When I went to download HTC Sync Manager, I see that the file has a new version than the one I have saved on my PC.
Just something to keep in mind for you S-On users.

Can't fastboot boot TWRP

So I've got a weird issue here, and after a sleepless night of Googling and using the MSM download tool, I still haven't figured this out. Basically, something got royally FUBARed while I was trying to flash LineageOS 16 to my OP6, and my phone got stuck in a point where not even TWRP would boot, and fastboot only brought up a black screen with a blue LED. After a bit of searching, I ended up using the MSM download tool to re-flash the stock ROM and recovery. I attempted to install TWRP after unlocking the bootloader, but every time I try to fastboot boot TWRP, it brings up that same black screen with blue LED, whether I use the official TWRP image or the blue_spark TWRP image.
TLDR; I got bricked, fastboot flashed back to stock, and now I can't boot TWRP to flash TWRP to my OP6. Anybody out there know what I should do?
Cheers,

With MSM tool your oneplus 6 is locked again...Maybe you should look if bootloader is locked!
Unlock BL
After its done you'll have to enable debug in developer options
Then fastboot boot twrp

Did you enable debug?
Sounds like you may have the active slot set to an unbootable OS. Check the active slot with fastboot getvar all, then use this to change to the other slot.
fastboot --set_active=[a or b depending on which is inactive]
Was this the end of this? I'm in the same boat. I was recovering from a google account remove device wipe and so I went to restore my TWRP back-up and it succeeds so I reboot. Device is bricked into fastboot mode only. So I msm restore and boot system, enable debugging, unlock bootloader, still can't get into TWRP or versions that worked before, just that taunting blue light.. I found this and changed my active slot but the issue is the same and I'm kind of at a dead end, any help would be appreciated. I can boot into 5.1.5 OOS and stock recovery fine.

I flashed DP3
OEM UNLOCKED (No Service--- Expected)
Ok now I need to flash a custom rom to get service back which means... flashing TWRP....

Did you try msm back to stock and start over?
Its a bit of extra work, but it usually works for a non-expert like me when I'm beyond my knowledge.
Also, iirc there's no reason to flash magisk if you're going to flash twrp cuz twrp unroots the device?
I would try msm back to international > unlock bootloader > fastboot flash boot twrp.img > flash twrp installer in twrp > flash magisk in twrp > flash your new rom in twrp.

Right, that's why I was suggesting you msm back to international which would put you on 9.5.3(?)
From there you can unlock your boot loader, flash twrp and magisk, and then flash your rom

so even though I can be on international, Without DP3 you can't bootloader unlock.
You can't unlock the bootloader on T-Mobile phones.

I'm not sure where you got that info, but it's definitely wrong.
Tmobile has a standard unlocking procedure, or you can utilize something like this or this if your device is not paid off yet.
However... if you are attempting the dp3 unlock method found here, and as of right now you are still locked, its because you skipped the actual unlock procedure. Which is literally steps 1 & 2 in this guide, attached in the previous dp3 unlock guide.
https://forum.xda-developers.com/on...obile-one-plus-7-pro-msm-tool-revert-t3936528
Step 1- Download the file in the original post, create a folder somewhere you know where it is and extract the downloaded files to that folder
Step 2-Turn off your OP7 Pro
Step 3-Open the folder you created and right click on MsMDownloadTool V4.0.88.exe and select run as administrator, Once open uncheck sha256 check.
Step 4-Plug the Original USB cable that came with your phone into the phone.
Step-5-Hold the Power/Volume up/Volume down button until you see Connected in MsMDownloadTool, the instant you see Connected press start. You only have 5 seconds before it's too late so be quick.
Step-6 Once you see "Download Complete" in green in the Status of Communication box in MsMDownloadTool the phone will automatically reboot and you should have the TMobile splash screen and be able to set the phone up through the set up Wizard.
If you want to use Android 10 with service working on your T-Mobile 7 Pro you NEED to be SIM unlocked.

That process doesn't work for Android 10 (OB1 and OB2). With OB1/2 the fastboot boot command doesn't work yet (similar to all the 7 Pro devices when it was first released). As the top poster already mentioned the correct method to get TWRP on the device is to flash a patch boot image. Form there, he can flash TWRP within Magisk.

"From that point" would have been 9.5.3 international not 10, and I was assuming he was already carrier unlocked.

Right. What you need to do now is download the full latest ota, put it on root of storage. Do local upgrade. After it will boot into stock recovery do a full wipe. Reboot. Then you can install twrp, magisk..ect
This way worked for me ^
(I'm not sim unlocked btw)
If you use msm it will relock your bootloader!

Is there some benefit to keeping the sim locked? Getting the sim unlocked is so easy. Then you don't have to worry about the bootloader relocking, cuz you can just fastboot unlock it.

Exactly, like why go through the trouble of using certain methods of upgrading, etc. to avoid relocking If you can just go to one of the unlocking threads on xda, or just talk to TMobile support on Twitter and get sim unlocked. Like the whole process took me 30 minutes and now I don't have to worry about it because it's officially unlocked. Like, I've had my **** in a boot loop a few times, and being able to msm all the way back to stock and reunlock etc is extremely useful.

Download something called "minimal adb and fastboot" (don't have the link handy) and use that fastboot to do the following:
fastboot getvar current-slot
Whichever slot it shows, a or b, you want to switch to the other. So if it says the current slot is A, you would type
fastboot --set-active=b
And if it says slot B, then you want to set A as active slot. Then after it successfully changes slots
fastboot reboot-bootloader
Now when you're back to the fastboot screen after your phone reboots, the fastboot boot command on your twrp img should work fine.

Root + TWRP on Android 10 Post OTA?

I installed the Stable Android 10 on my GM1910 via TWRP, totally forgetting about maintaining root and TWRP.
So how do I bring back TWRP and root?
fastboot boot doesn't seem to work, I managed to pull the boot.img and patch it with Magisk from another device but flashing it through fastboot ends up in an endless bootanimation.
Could anyone help me? here's a link of the boot.img i pulled, it works if you flash it without magisk patching it.
Link: https://drive.google.com/file/d/1O8lF1UDwwu0zT8ro5Q1gKKfdxF-HGPEW/view?usp=sharing
(Almost) exactly the same here. I tired flashing a patched boot.img, it actually boots - but magisk manager gets stuck on the splash screen and some apps, including chrome, won't start. Trying to boot TWRP results in the phone getting stuck on the "fastboot mode" screen.
My only solution would be to downgrade, root, keep the upgrade this time. But because my ISP is doing some maintenance work I don't have wifi - and restoring my phone through mobile data does not seem to work correctly.
EDIT: In fastboot, neither bootloader version nor baseband version are show, product name is "msmnile". Has this always been that way?
EDIT 2, solution:
I extracted the boot.img from the device, and patched it using magisk on the same phone:
https://drive.google.com/file/d/1-Gf-6iXSFuYT5xDR-mnLKANvkXUHal9e/view?usp=sharing
Run this command in fastboot so you know which is the CURRENT active slot :
Code:
fastboot getvar current-slot
Run this command so you can flash the correct slot :
Code:
fastboot flash boot_X magisk_patched.img
replace X with the a or b from the command before.

Hi sorry to hear that you got this problem and hopefully it gets fixed. I have another question: does that mean using TWRP to completely clean the device then installing Android 10 via zip will remove TWRP and fastboot everything? Does that mean after installing, everything will be refreshed like a box opened phone?

Either one should work if the rom and the rooted boot image is on it (If you are rooting). That's why you should install using TWRP, if you look in the reboot menu it will show you the active slot.

You are supposed to flash it in the one that IS the active one. Because you do want to root the slot that you'll be booting.

Same.
I've read that Q/10 is different and you can't install TWRP like that anymore. Supposedly you need to use the MSM tool or the all-in-one tool but I've tried both of those and still can't boot to TWRP.

Hopefully there will be a solution. I had tried to update from Pie to Q10 while staying rooted and it didn't work. So I had to wipe the whole device and decided to wait for a smoother root method for my device. If you have any other ideas about rooting Q10 let me know. Thank you

I updated my phone to 10 last night, followed the same guide as I have for every other update but this time I lost root for some reason.
I still have TWRP recovery on there but it can't read internal storage so I can't flash Magisk.
I tried changing file system to ext 2 then back to 4 and then repairing it as I read elsewhere and this wiped the phone obviously but internal storage seemed to be working until I set the phone up again, downloaded Magisk, rebooted to recovery and I'm back where I started, internal storage showing as 0mb in TWRP.
Any ideas how to fix?

flashed TWRP over boot slot B

I ended up flashing TWRP over my boot slot (B) and now I just boot into TWRP. I have already installed TWRP on boot slot (a). I can't remember which version of oxygenOS I have installed and couldn't find a way to confirm. How can I fix this? Also want to update to latest version of oxygenOS and android. No data on phone yet. phone still connects to computer, adb sideloader and fastboot commands still work work. Thanks
Are you saying you did fastboot flash boot of the TWRP img? You should be doing fastboot boot TWRP img, then flash the TWRP installer zip.
You can get the OS back up and running by flashing the correct boot.img via fastboot. Or use one of the fastboot stock ROMs.

ya, I fastboot flash boot the TWRP img following this video youtu.be/3oSycujvmP8?t=296
I guess I'll start flashing boot images until I land on the correct OS version, thanks

But to recover his phone, the OP will need the original boot.img from his OS version.
OP has already messed up the boot partition.
That has to be fixed first.

in this case the best thing to do is just unbrick using MSM

Yes, I had to unbrick using msm. It worked. Was able to get phone rooted and stock recovery replaced with TWRP but it was a much bigger pain than I expected.

Glad you got it recovered.
There is an application called "Partitions Backup".
It allows you to back up all the phone partitions. The one you really want to backup from now on is the boot_a and boot_b.
Since you are rooted when you do an upgrade, grab the boot_a and boot_b before installing Magisk after the install.
This allows you to go back to stock. After you back them up, copy them to a computer.
hey guys. Not able to flash oos through twrp.

Doesn't TWRP back up everything including boot partitions?
Is there nothing that will take the entire internal storage and just make a 'bare metal' image of it for restoring.. the whole entire thing, byte for byte? If not, why doesn't this exist? It just seems so logical to me and would be so incredibly useful. Phone borked? No problem. Just re-image it form the archive you made. To me, that is what TWRP is all about, at least conceptually if not technically.
