Question Help returning T Mobile Oneplus 9 to out of box settings - OnePlus 9

Hello all.
I have a Oneplus 9 T Mobile variant that my son and his friend tried to install a Global Rom and I would like to return it back to stock. Problem is they lost track of what they did and now I do not know which way to go. I've read many threads and tried to educate my old ass before reaching out to you all. I used to be tech savvy but have been out of the game for far too long to remember most of the tricks. I would really appreciate it if someone can patiently guide me. I like to thank you in advance.
What I got out of them is they used THIS thread as a guide and magisk to root. They never backed up the stock rom and may have only flashed Slot_a. They uninstalled root to see if that helped. The phone works but can't update due to the unlocked bootloader that is greyed out. This is some info

Just would like to get it back to stock just where it was when I received it new. Thank you again.

Find the msm tool for your variant. It's here. Hold all 3 buttons,vol+& vol - plus power . This reboots edl and allows you to start msm tool. It restores to factory condition and locks the bootloader. Google msm tool for op9 to find out how to use properly.

This the one bud. And good luck

It worked! That was way too easy.
Thank you so very much my friend. I really do appreciate it.

And btw the device will update properly with just the bl unlocked. It's when you get into rooting and patching partitions that Google -ota runs a checksum on the partitions ,detects tampered and update fails. Enjoy your device

Unable to boot into Clockwork Recovery on Nexus S

Hi all,
You may need to bare with me a little with all of this, I'm extremely new to it all.
I picked up my Nexus S on Monday after previously owning an iPhone and then a Windows Phone 7 handset, firstly I have to say that I can't believe I didn't get an Android phone sooner - they're leaps and bounds ahead of the competition in my opinion and offer a much better!
With the help of a set of instructions I was able to unlock the bootloader and flash the recovery to use Clockwork 3.0.0.5, from there I was able to install Superuser from the ZIP to root the device.
Everything is working and rooted but whenever I try and get into the Clockwork recovery it keeps chucking me into the standard recovery, I've tried from the bootloader and from ROM manager.
The problem I have is that I can't backup my ROM because it just takes me to the standard recovery and sits there.
I had a look around but couldn't find anything relating to this on the forum.
There was mention of something called 'sgs kernel flasher' but it states it wont run on Gingerbread which I'm running.
Any ideas?
If you have any questions of something I may have missed out I can answer those!
Sosmething very similar to me recently. I just reflashed the clockwork recovery via adb/fastboot and works like a champ now.

Thanks for the help guys, as I said I'm quite new to all this so sadly the thread title:
"Q about cwm 3.0+ and 2.3.2"
Didn't quite stick out to me!
Problem sorted now though, all backed up and new ROM installed - happy days!

unlock bootloader steps given to me by motorola today

So..an error occured on my motorola razr hd xt926 183.192.15 (built in july) while downloading an app and I had to go to Motorola to get it fixed. Motorola rep gave me a link to enable the ability to unlock my bootloader allowing me to install a custom recovery and then flash a rom to fix my problem. He matter of factly told me this would work. I am waiting for this phone to get off work so I can make the attempt. I'm pretty new to rooting and unlocking so I thought it would only be right if I shared this info. I was trying to share that link, however...my newness status will only allow me to drive you crazy with repetitive questions, or gloat...
If you want the info you can pm me I think...I've been gutting and restoring my laptops lately so forgive my forum skills.. If you know another way...lead on....

Yeah, I having this same exact issue. It's driving me nut because all I want is my stock s7 back :crying:
So after three days of constant research, I have come to the conclusion that I'm slow. This entire time I was trying to flash unroot a phone with links to firmware from forum post made four months ago. Im pretty sure we can see the problem in that. So long story short I found this beautiful website with (great) download speeds called sammobile, from there I was able to find the latest firmware that led me to bring my beautiful phone back to stock goodness! So in my concluding statement I have to thank you xda for actually making me learn something.
I can't put a link but for you sfear2ugf just go to sammobile and look up G930T in the searchbar and use the latest kernel.

Where can i download the latest application? I have an older version I found on the internet that I am about to use to attempt unlocking a Samsung Emerge SM-J327P. Would love to have the newest out. I see a different (looks newer) version in this video - https://www.youtube.com/watch?v=kQXvCl0ZYFQ
This handset (J327P) is a hard one to unlock. I already tried the bit3 firmware / combo flash method but MY Z3X SamsungToolPRO wouldn't read the SPC / MSL for some reason. I don't know of anything else that will. My Octoplus box doesn't seem to be able to do it either unless i'm missing something. So trying this solution on the firmware indicated in the video I have already flashed. Hopefully all will work!
Hi there. Just want to say Hats off to CdmaDev Yemen Team, Mysterious Dev, and the rest of you guys lately. You have really pulled through with Sprint with their latest RSA in place and all. Not to mention Tracfone and StraightTalk!! I speak with some of your team now and hope to work on a few things in the future. I started the J337P unlock here to see if i could do this one and you guys already had it done. =] BillA and Austin? i think mentioned on GSM-F.

I have a SM-J337P phone that I need to unlock from the Sprint network. The cdma-yemen.com website is gone. Do you have a copy of the software mentioned in the first post or some other free software to do it?

One Plus8t stuck in boot menu please help me

Hello guys I hope you are well
I have a problem with my main device one plus8t
I unlocked the device and installed the first modified ROM for me and this was great, but an internal update came to it. I updated from the phone itself and then the phone stopped responding.. the touch stopped working. I was worried I didn’t know what to do so I flashed the ROM again in the same way I did it the first time in the hope that it would work again, so when the flashing was finished, what happened was that the phone stopped on the bot menu, and any thing I do turns off and returns to it, it does not enter the system .. Now I do not know what I should do. It happened 6 days ago and since then every day I sit for hours trying Methods and solutions and no solution works. I
Sorry if my English is bad because I am writing with a translation tool
