I have an ATT phone currently unlocked and using it on T-Mobile. I want to root and use it on T-Mobile, but Im a little nervous that once I root, and wipe everything, the phone will be re-locked to ATT. So my question is, once I root will I lose my carrier un-lock?
It might be helpful to clarify a couple of things. It sounds like you're currently SIM-unlocked (thus able to use your AT&T branded M9 on T-Mobile). Are you currently bootloader-locked and want to unlock it so you can root? Or are you already bootloader unlocked?
Rooting definitely does not wipe/re-lock anything. Unlocking your bootloader triggers a system wipe. My understanding is that once your phone is SIM-unlocked, system wipes don't affect your phone's SIM status.
Sorry for the confusion. I am currently sim unlocked, and I want to bootloader unlock. However, before I unlock my bootloader, I want to make sure that I wont re lock my sim. My ultimate goal is to unlock bootloader in order to root, but I dont want to relock my carrier to ATT. Yes, it is an ATT phone and I'm using it on T-Mobile.
I'm pretty sure that unlocking the boot loader will not affect your SIM-unlocked status.
But if it were me, I would want a more definitive answer than that.
Another forum member may be able to answer for sure. In the meantime, consider asking HTC directly via their chat system. I've found them friendly and straightforward.

No you won't lose your unlocked network status.
The unlock once done is permanent.
There was one a while ago on the s3, an app, which was unofficial and I lost that a few times between flashes, but I don't think you'll have that issue.
Thank You. Unlocked boot loader, rooted and still have sim-unlock.
Simple question but can't really find the answer online.
Bought an H815, no carrier label etc. My ATT sim works in it.
I want to unlock the bootloader (OEM process) root, add TWRP and flash custom ROMS. Will this affect the factory unlocked carrier status?
How is it carrier unlocked btw , at the hardware level or bios type process? I see the H815 comes factory carrier unlocked?

Assuming your phone was purchased sim free, then no, bootloader unlock shouldn't affect it. You can always make a backup with SALT first (bootloader can be locked when you take the backup) so if for whatever reason it does get removed then you can restore it.
Btw, LG's don't support fastboot oem unlock. You need to do it via Official LG bootloader unlock website or UsU (look here in the threads) if your device isn't supported officially - if it is an EU H815 it official should work though.
fr eBay sim free. I'll look into the SALT backup.
I did a bit of work already and signed up as an LG dev and do see the LG website process which I was going to do to start.
So then adding TWRP and a custom rom will not affected the carrier unlock as well?
thanks

i have h811 TMOBILE phone i got it unlocked. it was unlocked by tmobile.
i unlocked bootloader and carrier unlocked keeps it unlocked no matter what. ive flash this phone so many times.
thats just my experience
OK thanks, Had a bad experience w a Samsung Grand Prime which I do not want to relive.
So i have the tmo op 9 pro and I used to make cross flash zips for the lg v30 and op 7 pro sprint. I wanted to do the same for this device as well but since the bootloader unlock is a little different, I had some questions. Since I was able to bootloader unlock by bypassing the sim unlock the using MSM to convert to EU I was worried I would lose the bootloader unlock in the process of this. Basically I want to take a stock tmo payload.bin from A11 and then unpack it and use the imgs inside (minus the device specific ones of course) and make a twrp flashable zip so I can go back to TMO firmware. What I'm worried about is since I didn't sim unlock I would lose the bootloader unlock in the process. Any thoughts on this?
Bump
I'm wondering the same thing. I'm on tmo op9 pro as well. Unfortunately it updated to a12. I got oem unlock button when that update came tho, but it still asks for the unlock.bin... I put in for my unlock code to op, got it back but haven't tried anything yet. I also do not have SIM unlock as it hasn't been 40 days of activation yet, and the phone is not paid off. I was also an op7 user and it was way easier to get this done. I would like to have root again soon.....
Question:
I own a T-Mobile account. Just went through major drama w/ amazon seller, a T-Mobile phone that wouldn't unlock because it wasn't paid off, and more. Never mind that.... sending it back.
I want to know if I can buy a non-US and/or unlocked OP 9 Pro and still have it work with my T-Mobile sim?
I want in the end, ideally, to have a OP 9 Pro running the very latest Oxygen OS/updates and have it be rooted. But again, w/ a T-Mobile sim.
Advice? Has anyone else faced this?

Don't send back.... Using the T-Mobile app and chat you can be over complementary and ask for full unlock and should be able to get it that way. Option 2 is to use a modded MSM tool to convert to Global, unlock bootloader, us a modded Glo to TMO MSM TOOL to get back to TMO firmware and update. But recommend to stay away from A13 for now

Was your recommendation to avoid updating based on the trouble that DaveImagery was having with achieving root? If so, I can assure you rooting the T-Mobile android 13 update is no different than rooting the global or eu firmware, aside from having to always temp boot TWRP rather than actually install it. TWRP acts up sometimes but it works. I think he was either having a problem with the driver's, USB port, or cable, or something went wrong when he pulled the boot image via MSM tool.

If you got the factory unlocked one then sure, it'll work with a t-mobile sim. The question is whether it will be 100% compatible with t-mobile's network or not. I don't know the answer to that question. It's worth noting however that the T-Mobile variant is slower to get updates, and just got Android 13 this month. If I'm not mistaken, the global and EU variants got Android 13 last year. This fall/winter the other variants will probably be getting android 14, while the t-mobile variant waits until next spring.
T-Mobile updates are slower because they are more refined and sometimes include multiple updates in one update. That is why they are slower..

im on an unlocked (purchased new) OP9 pro and I have no issues. I've always wanted to see if TMO modem works better, but it works great enough that it't more of just a curiosity.

I decided to stay with what I got, esp. as the seller also (belatedly) included the original 65w fast charger. I did a bit of whining. So now I'm trying to get my employer to leverage t-mobile into unlocking the phone, since we've been w/ them a long time and it technically is my employers' phone. (They appreciate my geek interests and are willing.)
If I can get it unlocked, the next questions will be about just how flexible T-Mobile's sim will be with various rooted Oxygen OS's.
I used to root all the time.... my Samsung Note 4 (dang I loved that phone), my OnePlus 2 (rebuilt from 2 broken ones... by me!), and so on. But Samsung's Note 9 wasn't rootable (I didn't have the Exynos version). So I got stuck. This time I bought the OnePlus 9 Pro intentionally in order to play w/ rooting again.
But the whole thing has gotten more interesting. TWRP... does it still work and do the awesome backups / restores of multiple different systems on the same phone? And Magisk.... sheesh... so much I don't know.

TWRP is a little wonky, Magisk is a yess!
If you have no luck through TMO with unlocking the bootloader, let me know. There is another way to do that.

How exactly would that work? I've read that using the T-Mobile->EU MSM allows you to unlock the bootloader without an unlock token, but wouldn't using another MSM to go back to T-Mobile firmware re-lock the bootloader? Would the fact that it's already been unlocked previously allow it to be unlocked again without a token, even after flashing back to the T-Mobile firmware? Mine came sim unlocked and didn't have any trouble getting an unlock token so I never tried the workaround and I've just flashed the unlock token every time.

I have a modded TMO to Glo and a modded Glo to TMO.....I have used it before....
So it is in fact possible to skip waiting for a token. You have to use MSM to convert to EU then you're free to do whatever since the bootloader is now unlocked? Am I understanding? I'd like to personally flash Lineage as soon as I'm unlocked, will the above process work for me?

I believe you. What I'm saying is that according to what I have read, every time you use a MSM tool it locks the bootloader. So you convert to eu, and unlock the bootloader without an unlock token, because this specific firmware is unique in its ability to be unlocked without a token. Then you flash the T-Mobile firmware with another MSM which locks the bootloader all over again, and now you are once again on T-Mobile firmware with a locked bootloader and no unlock token. My questions are:
1) Does the fact that you previously unlocked the bootloader permanently do away with the need for an unlock token, even after you MSM back to T-Mobile firmware and re-lock the bootloader?
2) If so then how do you unlock the bootloader the second time after you MSM back to T-Mobile firmware? Do you repeat the same procedure you did on the EU firmware, or do you just run the "fastboot oem unlock" command from now on?

The way it is done with the modded MSM Tool to go from Global back to TMO it does not lock the bootloader. Can't explain why, but it doesn't. A pure TMO MSM Tool will relock the bootloader. Been there and done both ways.
In a few days I will do it again just to triple check the procedures and create the necessary modded MSM Tool zip files to share.
Another way to get unlock token is by booting to bootloader and run the command to get unlock code. Copy the long list of numbers along with IMEI and serial number and email OnePlus support with the information stating the TMO unlock token website is not working for you and they will generate a token for you. I had to do that when my first token quit working....
