Possible to Downgrade From Android 11 to 10 on XT2113-2? If so, how? - Moto G 5G Questions & Answers

I have a new XT2113-2 (TM) that is yet to be boot loader unlocked/rooted/etc. I don't want to do that until I am sure. I got this variant of the phone so I could unlock the bootloader, root, TWRP, etc and was afraid the "global" variant -3 might not work with USA 5G. The phone came with Android 11 installed (and has since auto-installed at least one security update). It shows the build as RZKS31.Q3-45-16-3-11 and the baseband ends with Kiev_TMO_CUST. I am using it on ATT (via Red Pocket) since TM service just sucks where I live. And I do get the 5G icon on it now.
But ideally, I want to get this to the original TM Android 10, which I think is shown here as the file XT2113-2_KIEV_TMO_10_QZKS30.Q4-40-95-6_subsidy-TMO_SPR_RSU_QCOM_regulatory-DEFAULT_CFC.xml.zip as I hope it will undo some of the "security" crap Google has added to Android with each successive release.
So I need to be sure of the following:
1. Can I downgrade from 11 to 10?
2. Is there some reason to NOT use the firmware mentioned above? Should I use retail US (RETUS) instead? I am not sure the differences (it would be great if that would permit me to use this phone on Red Pocket Verizon but the IMEI now shows as incompatible on Verizon).
3. Must I unlock the boot loader to downgrade? I know I must to do other stuff and I have the unlock code on hand and ready to put it if needed. If I must unlock the boot loader to downgrade, will I have to re-unlock it afterwards? And, if so, will I have to go through the same process of getting a code or will the code I have now work?
4. How do I flash to do the downgrade? I have the Lenovo Rescue/Smart Assistant installed on my PC and was able to download the stock firmware (I assume it matches what is on there now) and stashed it aside. But is there some other tool needed?
5. Once I achieve downgrade, what is the best way to avoid having the thing auto-update to Android 11?
Thanks for your help with these questions.

If you are going to take this phone to AT&T, you will not get 5G if you unlock the bootloader. The NR band will be restricted. Downgrading from 11 to 10 generally doesn't work either.
I can't answer the rest of your questions.

Thanks for this response. I do have it on ATT (via Red Pocket) now and it does appear to get 5G now. I have not yet unlocked the bootloader, was thinking to do it, but considering that it would cause loss of 5G I think I will not and will just return the phone. Wow!

BTW - have you any references on this behavior? I am wondering if this is something that would affect ALL phones with unlocked boot loaders (like Pixel, OnePlus, etc). Thanks for the heads-up.

WARNING: ONLY DO THAT IF YOU ARE REALLY SURE AND DO BE CAREFULLY. I recommend you: do it not.
By downgrading to an older software, the bootloader in many cases can be destroyed, so your phone is completly bricked!
I write this from EXPERIENCE. My amazon fire is completed bricked, when i have flash a older SYSTEM. It can't turn on, no fastboot, no recovery!

I suspect, but don't know, that all phones with unlocked bootloaders are blocked from 5g from AT&T. I know my kiev (RETUS) is.

Thanks. Yet another reason to dislike ATT, I guess. Sadly, in my area TM coverage stinks. And this phone will not work on Verizon (unclear why but they reject the IMEI). And getting the Verizon variant will preclude ever rooting the thing. So I really feel trapped!

Likewise

as my IMEI SV on the Metro/TMO variant is 05 rather than 07. Never tested with a locked bootloader though.

The discussion is about an unlocked bootloader, not an unlocked carrier situation.
If an unlocked boot loader version existed, it would be called a developer version and it wouldn't be likely to be picked up in large enough numbers to see much real public development.
Basically, it will most likely be MONTHS before you see a leak or hack to unlock the boot loader if EVER. It will be a long time before you even see root if the G4 and V10 (just got root very recently) are anything to go by.
Since mobile device payments have become all the rage, carriers and device manufactures are extra motivated to lock down their devices. The Galaxy S7 and S7 edge (same processor as the G5) are so locked down (even on T-mobile) using Qualcomms secure boot methods that it does a check to verify the main partition before it loads the contents to memory meaning a root can only be done temporarily (live rooted) if an exploit is ever found and will have to be rerooted every reboot. Android developers are going to have to struggle with qualcomm devices especially to develop into the the future.

If the G5 is carrier unlocked, then wouldn't we simply be able to purchase a T-Mobile variant, get it unlocked, and then use it with a Verizon Sim?

As long as you don't mind paying full price or carrying a second contract and T-Mobile agrees to unlock it. Hopefully development would still be decent with just the t-mobile variant.

Unfortunately Verizon is very strict on what devices can be activated with one of their SIMs. Most likely they would block a Tmobile or international variant on their network. This is the case with the G4 already.
We got root on the V10, not an unlocked bootloader though (yet). Here's to hoping we can get at least root on the G5 in the same manner...need those magic TOT files!

We will need more than the TOT file to root the G5. Starting with Android 6.0, Google made changes so that root requires a modified kernel. Changes to system.img will not be enough. Since this involves tampering with the boot.img, the locked bootloader will prevent the phone from booting at all.
Here's hoping we don't have a repeat of the G4 or V10 when it comes to locked bootloaders.
Should I not update my device to keep it as developer friendly as possible (I am preordering it)

Installed wrong version

I'm in a Verizon pixel and installed "v" version instead of "u" everything is working. What's different about the international version?
Just a fix for European carriers. I'm using the same on Verizon as well with no issues. You're good.

Nothing it will work just fine. From what I understand just a slight difference for Europe. It will be fine.
What I'd like to know is if I were completely stock on V, bootloader relocked, what updates would I get, if any? Would I get the next version for Europe, or would it be the other? I'm in the US on Verizon (device from Google).

You probably wouldn't get any updates. The trigger for that version probably wouldn't get to you. But I am not certain on that. Might be able to pull it via wifi with no SIM in it.
Do NOT relock your bootloader unless it is just before you are going to put it in a box to send back for warranty.

Why would you think you'd get the European version if you are in the US? Did I miss something in your question? You'd get the U version if you're on Verizon and you can lock and relock the bootloader at your discretion since you have the Google Pixel. I mean if you want to keep wiping your data each time, that is.

He made it sound like his pixel is from Verizon. In that case he can't lock and unlock the bootloader whenever he wants.
To the OP. What are you trying to do? It doesn't matter if you are on V. If it makes you feel better just flash U then. As long as you don't have twrp or root you will still get OTAs. Why would you want to lock your bootloader? You can have an unlocked bootloader and still take normal OTAs just fine . it its a Verizon sold pixel you won't be able to unlock once you lock.

Unlocked Z4 Bootloader vs Verizon Z4

So on motorola.com they offer the Moto Z4 Unlocked and the Moto Z4 Verizon. Is it possible to unlock the bootloader on the unlocked version? I know Verizon locks down all phones. and is it possible to use the carrier unlocked version on Verizon? I know some of the old phones didn't have the correct band to work with Verizon's network but things change and Verizon is now offering bring your own device now.
I'm still rocking the Z force with the shatterproof screen is there any news if Motorola going to bring it back on any new phone?

No its the other way around its easier to root the phone after you unlock the bootloader. To root your Android phone (i.e. gain administrative access), you'll need to unlock your bootloader first.

That doesn't really do anything especially on the verizon model. On the unlocked carrier version you need to switch that on then unlock the bootloader with a code that motorola gives you.

That is true with a lot of phones but that's a temporary root or a hacked root. Verizon doesn't like their phones to be rooted or bootloader unlocked so they send "security" updates to patch root access to phones that developers found hacks to gain root access to. But if the bootloader is unlocked they can't patch that so you can remove root update your phone then root it again very easily.

actually called VZW about this a couple weeks back, tier 1 guy went "uhh, hold a sec, I'll get you to tier 2" tier 2 "good question, i need to ask network and provisioning" the eventual answer was yes they will work.
The only problem i can see, is from what i understand, moto mods are hit and miss with custom roms, so stock will be fine, custom depends.

That's a negative here on my end. Verizon z4 and everything was good until I entered the code from fastboot into the field on the moto website; says "your device cannot be unlocked". love verizon.
I have a brand new Z4 XT1980-3 that I just unlocked (bootloader unlock). The only problem with this model is that WiFi calling and Video calling are not possible on Verizon. Apparently they don't support those features on the XT1980-3. Those features are only available on the Verizon version (XT1980-4). So now that I'm bootloader unlocked, can I just flash the XT1980-4 firmware on the phone? Is that even possible? And will it enable the advanced calling features? I already downloaded the May 2019 firmware from here: https://www.getdroidtips.com/motoro...e-and-firmware-collections-back-to-stock-rom/
Just want to make sure it's safe to flash, and if it will in fact enable WiFi and video calling on the Verizon network. Thanks!

Which T-Mobile 5g phones are best for rooting.

Hi guys, I am hoping I can get some help since I am needing to get a 5g phone on T-Mobile and root it to tether with. And since I am adding a line, I could take advantage of their half-off deals, but I need to know if there are any 5g phones on T-Mobile that will let me root it while it is technically still locked to their service. I know when I rooted a phone earlier this year it was just assumed that it needed to be carrier unlocked first, so it's hard to go look at individual phone forums and see if their unlock methods would work for me or not. Is it possible for any of their offerings to be rooted while still be locked to the carrier?
Thanks in advanced.

All that really matters is if the device has an unlocked bootloader or, at least, a bootloader that can, in fact, be unlocked using a known/proven method for that exact device.
Devices that have an unlocked/unlockable bootloader can easily root using the Magisk method and/or TWRP, but, not all devices have TWRP available to them. But, the Magisk method works for most devices, provided that they have an unlocked bootloader.
Yes, it can be locked to a carrier and still be rooted. When you see guides discussing unlocking a device in order to root the device, they are not referring to carrier unlocking the device in order to root, they are referring to unlocking the bootloader, which must be done in order to make modifications(such as rooting) to the system software.

Your current version does not matter. This will flash phone to point that it was when it came out of the box. then you can start over.

How do you back up the T-Mo modems without going thru the T-Mo bootloader token unlock? I want to try going back to the T-Mo modems to see if they resolve the issues, and then back them up when to reflash when I go back to the EU load.
Thanks!

Well, I guess it ended up not mattering much in the end. At least for what I was trying to do.
I'm finding T-Mo's service to just be complete crap, and I've determined it's not the phone. I moved 8 lines over from AT&T. Half were BYOD (all unlocked AT&T Samsung devices, and my son's unlocked OP9), and the other half were Samsung and OP phones bought from T-Mo. Everyone's experiencing bad call quality and coverage issues. Both my family and in-laws live within a mile from known T-Mo towers where we live. I live in a major metro area, my in-laws in a rural area. My parents live in a medium sized city. It's gotten unbearable, and at times, my wife and I have had to resort to texting due to the call quality just being so bad. Cutting out, garbled, etc.
In-laws also have T-Mo's home internet and are having issues with that.
I don't get it despite everything good I've read about T-Mo. None of us had these issues with AT&T.
I'm going to try to work it out with T-Mo, but at least for the time being, I'll just go back to the European ROM. There's no difference in the call quality anyway, and at least there I have root again.
If i flash the T-mo firmware to a global model, will I be unable to unlock the bootloader simply with the adb command, or will I have to go through all the hoops as if I bought the phone directly from t-mobile?

Yes, but the phone has to be SIM unlocked first.
There is someone who can SIM unlock on here for free, with donations encouraged.

I'm gonna use the T-Mobile sim card on a global version of the phone. So theoretically the phone would already have been sim unlocked out of the box. What I'm asking is, if i choose to use the T-Mobile msm on the unlocked global model, will it carrier lock me in? If not that means all i have to do is go to developer options and use the unlock command, right?

No that won't happen to you. You should still be SIM unlocked as flashing software doesn't deal with SIM Locking but it May Lock the Bootloader that I am not Sure of

Who's currently doing sim unlocking? I'll gladly donate. I've unlocked my bootloader, flashed Magisk and have root access but I'm still sim locked to TMobile.
