Operating system does not start OP 7T. - OnePlus 7T Questions & Answers

Hello, I have the following problem when you installed an OS and the cell phone is restarted for the first time and the circles appear (red and white) only last 4 seconds and then the cell goes off and it does not start the OS.
This same error happened to me by installing Pixel Experience 12, DerpFest and installing the Rom Stock (using MSM). I hope and can help me.
PD I can access the bootloader but I can not unlock it because of Android 11 to 10.
Model: OnePlus 7T (HD1900).

Hi, I tried that method but when you are sending the files an error appears (Device Not Match Image).
Regards.

What did you exactly did that system won't start?
Did you flashed wrong boot.img or something else?
Did you tried easiest method which is Hold Power+Vol Down for few second untill you feel 3x vibration and then release. Check this out.

Hello,
1.- I had pixel experience 12 installed and I used it without problems for 3 days until I installed YouTube vanced and it asked me to restart, when I was loading the "Google" logo the cell phone turned off (the same problem I have now). I reinstalled pixel experience but still got the same error.
Then I installed DerpFest and finally stock ROM via MSM and the same problem persists.
2.- I never installed any boot.img
3.- Doing power+vol down only loads the recovery stock Ver.2.0

did you get the T-Mobile version or just regular version from OnePlus?
the T-Mobile variant needs an unlock code. the OnePlus direct version you unlock directly using ADB

** fastboot flash boot magisk-patched_boot.img **
The instructions are already on XDA. Just Search for them
I seem to be having a horrible time rooting my 7T (purchased directly from OnePlus). I've been able to unlock bootloader, and patch an img file via Magisk.
However, the results are either getting the Qualcomm crashdump--or successfully rooting, but breaks the wifi. (Haven't tried inserting the SIM Card yet.)
Already had to use MSM tool a couple of times.
Is there a definitive guide with build versions?

Same.
Did you ever figure it out?
I just install twrp 3.5.10 or Chinese twrp, and flash Magisk.zip (rename magisk.apk to magisk.zip) on top of OOS11
Which root method did you use?
One of these...
Or this
longer, slightly more involved one?
Make sure the new version matches the version already one the phone

How to relock bootloader for T-Mobile OnePlus 7T?

Hi,
I recently unlocked the bootloader for my T-Mobile OnePlus 7T and it is working fine but now I want to revert back to relocking the phone so I can get the new update 10.0.7 from T-Mobile installed on the phone. I haven't rooted my phone.
Everytime I try to install it keeps giving me the installation failed message. I tried to relock the bootloader with the commands I found online but then the phone gets stuck on the Magenta T-Mobile sign and don't boot up.
Can someone please help me resolve this issue?
Thanks

If I download the msm tool, where do I find the software update file for the current version of TMobile 7T which is 10.0.6.HD63CB?
Thanks
Restore it to TMobile factory and then you can update through the phone. No need to do anything manual.
Or, you can Sim Unlock and switch to International Firmware. This puts you on 10.0.8 although its only January Security patch.

As said below, you have to go back to 100pct stock with the msm tool.
Something about a bug in our hd1907 model that deletes an important file upon bootloader unlock that won't allow updates to complete anymore and there's no fix. In fact, Tmo is doing warranty exchanges cause it's a known issue, but we have the msm tool now ?

Just a little help please unlocking bootloader/Root TMOBILE Oneplus7T(Sim unlocked) without Oneplus code

Does anyone know a way to unlock the bootloader of Oneplus 7t without asking for an unlock code from T-mobile? I was able to get it network unlocked however never rooted it. Even on my oneplus 5t which I'm trying to root(got bootloader unlocked) I can't root because it says "waiting for device" when trying to flash the twrp.img file and that phone is a global variant. It seems like I'm having issues with both for "waiting for any device" through adb.

Fastboot flashall files to OOS10 and then use oxygen updater app to install OOS10 (or adb sideload OOS11.zip once installed TWRP3.5.10.img on GitHub). Root can be done by installing magisk canary APK (renamed to zip) in TWRP

I got it rooted and will try to flash to global android 11. I didn't have to do a unlock code token OR follow the tmobile to global flash root. I don't know why but when I clicked unlock bootloader on "TOOL ALL IN ONE" it unlocked the bootloader lol.(Sticky to save time?) I got root by using this method. https://forum.xda-developers.com/t/...7t-sim-unlocked-without-oneplus-code.4288179/
Do I have to unlock bootloader/root everytime I flash a ROM?
How do you usually do a backup easily so I don't lose stuff next time

I bricked my 7t. It only loads into fastboot mode and MSM downloads are giving me error"disk file missing" or something...each version/site that I try on google. So now I'm using 5t(has root...not caring about updating it...backup phone anyway) while trying to get 7t working again....I would like it to flash to global latest oxygen...but now I have to unbrick somehow. I know for sure the phone isn't booting into an operating system.

Was msm working before? If never worked prior then you need Qualcomm 9008 drivers
Your phone must be completely off to enter msm or edl mode: holding vol+ and vol- together while plugging in usbC--msm program must be running with admin privileges before plugging in your usbC. Once sound is made in win10, then click start

OnePlus 7T Bricked

Hi, I have a oneplus 7T that belongs to T-MOBILE, I decided to make it global, after doing the process I made the mistake of blocking the bootloader after that the terminal does not pass the error "Your device is corrupt. It can't be trusted and will not boot ", I can only enter the fastboot mode, I have tried to enter the EDL mode to do the process again through the MSM through the adb commands and through a deep flash cable and np I have been lucky.
I have also tried to unlock the bootloader but it does not allow me, because it gives me an error related to that I have to enable unlocking through the android developer.
The pc only recognizes the terminal as "Android Bootloader Interface".
So if you can acces the fastboot mode have you tried flashing a oos10/11 fastboot rom ?

Yes, I tried, but it gives me an error in the transfer of the files.
Never relock bootloader as easy to hard brick. Try to set up msmtool on another pc and good usb-C cable. Also u should move this post to Q-A
Hi
I had is same problem, and is very easy to solve.
You only have use the method for which to use for covert the device in global versión, but only
you must do the steps until the equipment is unlocked, and then instead of continuing with the procedure, what you must do is flash a stock firmware that corresponds to the region of your mobile.
It's all a matter of taking the procedure to the point where it allows it to be flashed through fastboot

It is not necessary to use the TMobile rom, you just have to get to the point where the phone is unlocked with the command "fastboot flashing unlock_critical" and then jump to steps 7 and 8 of the guide referenced in the link I shared.

Thank you very much, the problem was solved, I changed the phone cable and tried it with windows 7 and finally I was able to unlock the bootloader.

My Phone just bricked suddenly, I haven't unlocked my bootloader or have enabled usb debugging

I tried all the methods I could find on the internet and this forum,
I tied the EDL MSM download tool method where I do see the completed green status and I see the phone restart and onePlus logo but its just shutdowns, I tried so all the versions of android and all the variants Indian (which is mine) and then Global and EU
becs my phone is locked I don't know what else to do , Please Help
When the phone got bricked first I tried to restart it several times and it did start but after 30 40min it happened again but after doing the EDL method most I could get to is seeing the one plus loading screen (rarely) whenIi restart several serveral times hoping to enable usb debugging and enable oem unlocking
