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?

You can indeed unlock the BL on the unlocked model, and I do believe it is compatible with VZW, however, the Unlocked model won't work with the Verizon 5G Moto mod, even if its on Verizons network. I believe only the VZW model will work with the 5g mod...

Thank you its still a fairly new phone but you would think there should be more info on it. if you ever do unlock it can you post a video please.
I have ordered the phone from Motorola, looking very much forward to using this phone with a custom Rom like LineageOS so I am hoping the Rom support will soon pick up. Here is a good walkthrough I found for unlocking the bootloader.

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!

I notice that the Moto G LTE from Cricket wont permit the Bootloader to be unlocked.
I am wondering, if you have your Cricket Moto G LTE unlocked (by this i mean sim unlock, not bootloader) and you then flash another carrier stock image - i.e. XT1040, etc - would it be possible to then unlock the bootloader? (I am assuming that if you flash XT1040 on XT1045 it's the same hardware, the only issue would be the radios..but if it's sim unlocked, then it shouldn't matter)
Or, is Motorola going by the IMEI #, which would stay the same if you flash another factory image?

Please update if you're able to get this to work.
Pretty sure the generated code is determined from the hardware. So flashing another ROM wouldn't change it.
That being said, I'm pretty sure Cricket versions of the Moto G LTE are never getting Lollipop. I spoke with a Cricket rep yesterday and they said the company had no plans to upgrade. So unless someone here can figure out some magical way to unlock the bootloader, we're all screwed.

I also talked to a Cricket rep yesterday about a Lollipop update. He said it was going to be a manufacturer, not carrier update. I asked him again to confirm because of what Motorola's site said. He confirmed again that it is based on what the manufacturer (Motorola) wants to do.

You can't flash ANYTHING with a locked bootloader. Cricket can update it, should they choose to, but as far as Motorola is concerned, Cricket owns the phone - not you. You can't unlock the bootloader unless you bought a RETAIL version of the phone - like I did from Amazon. You paid a lot less by buying the phone from Cricket and, in return, you gave up all right/hope of having an unlocked bootloader.
And, yes, everything goes by the IMEI, which is unique to the phone and never changes. If it were to change, your phone would no longer work on your carrier. The phone using that IMEI is registered as belonging to Cricket - that's why you can't unlock it on it the Motorola site. For the phone I bought at Amazon, I just went to the Motorola site and had my phone bootloader unlocked in five minutes. If you want a bootloader unlockable phone, you don't want to buy it from a carrier.
Update
I just spoke with Cricket who forwarded me to Motorola who said that my Moto G (1st Gen, LTE), purchased through Cricket, would be updated to 5.X within a month.
I'll try to update this if it actually happens. I didn't ask about the bootloader.

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.

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)

The bootloader can't be unlocked on Motorola's website, someone on Telegram unlocked the bootloader of his Moto G7 Power he bought at AT&T, he sim unlocked it then put a MetroPCS sim card int here and unlocked the bootloader. What I'm wondering is if I get my phone sim unlocked, will it change the CID number? Will it make the bootloader unlockable? Will it change the bootloader? I've tried flashing MetroPCS firmware and Retail firmware, both times it changed the BL:MBM number on fastboot, so did that change the bootloader? I appreciate any help in advance. Thank you.
Nothing you can readily do will change the bootloader unlockability.
Someone unlocked the bootloader on AT&T Moto G7 Power yesterday, he said all he did was sim unlock the phone then he put in a Metro PCS sim card and then he unlocked the bootloader. Obviously it changed the bootloader because before that he wasn't able to unlock the bootloader. I know that Cricket, AT&T, and Verizon all keep their bootloaders to where they can't be unlocked which should be illegal especially since I bought the phone outright and I own the phone.
I haven't seen the details.
How was it SIM unlocked?
Changing the SIM should not change the code that is submitted on the website.
The details are on the Telegram group, he sim unlocked it by calling AT&T.

That may have updated the code or Motorola's database so it pases for bootloader unlock.
What are the unofficial lock routes? Because obviously it's possible to root this phone somehow.

One way is buy an unlocked phone instead of one SIM locked to a carrier. Those can be bootloader unlocked out of the box.
Or go through the carrier. Policies vary so you should ask them. It appears from above that AT&T unlocking allows bootloader unlocking. That may not be true for all carriers.
There are 3rd party ways to remove a SIM lock, but that provably wouldn't allow for bootloader unlocking.
So has anybody been able to unlock bootloader on Cricket Moto g7?
I know a guy who can help but it cost money

Not always true. Carriers can gray out the allow bootloader unlocking option. I know Cricket did so on an E5 Supra (Plus) I have and I just got an Xfinity G7 Power & it's the same way. Even though it remains grayed out, the E5 allowed the bootloader unlock after I got the carrier code from Cricket, but then it's not on Motorola's site so it remains bootloader locked. The G7 Power was just the opposite- I paid to have it unlocked (cheaper than a month of service). I input the numbers from ADB there and got a bootloader unlock code from Motorola right away. When I tried to use it, it failed since the bootloader unlock option on the phone remains grayed out.
From what I've read here, the Metro G7 Power is the only carrier phone I've seen that is not bootloader locked by the carrier.
Hi, did the comcast phone have an unlock app on it? Who did you use for the unlock pllease?
I bought the supra today and sadly motorola website does not support it for unlock all other versions can be however I am hoping someone finds work around at least for root etc but totally want a bootloader unlock more than anything root and twrp without it I dont even really want the dang phone

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.

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!

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.

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

I always figured it was this
English Community-Lenovo Community
as my IMEI SV on the Metro/TMO variant is 05 rather than 07. Never tested with a locked bootloader though.

Bootloader unlocked Pixels work fine on ATT 5G, don't know about OnePlus.
