Flash AT&T ROM to Verizon Variant - Moto Z2 Force Questions & Answers

Hi! I'm using the Verizon Variant of the Moto Z2 Force on Red Pocket Mobile right now. I'm using AT&T towers and everything works great except LTE. I can force it into LTE, but my calls won't work. When it's in LTE/WCDMA mode it falls back on H+ everytime. While H+ isn't slow and has been good to me, i'd still like to get LTE. Can I flash the AT&T stock ROM to my variant with success? Or is there another method of getting my phone to lock onto LTE while still having WCDMA/GSM on standby so I may receive calls also?
I previously had a Verizon Samsung Galaxy S8 Plus which had the same issue on RPM, it wouldn't lock onto LTE. To fix this issue I flashed the international ROM with odin and it worked great locking onto LTE instead of H+ after flashing the ROM until it took a tumble down my basement stairs. So that's why I thought it may be possible with my Verizon Z2 Force.
Thank you!

We can not cross-flash between variants without unlocking bootloader. ATT and VRZ are both bootloader locked ones. It seems no one had done it before.

Wow, that bums me out to hear that.

Hey, I too am using the VZW version with ATT service, and I know exactly what you mean! Same problem here.

[Q] T-Mobile Variant on Verizon

I just took my Incredible 2 for a swim in the pool and it is currently drying in a bag of rice. Hopefully it survives, but if not - that would give me an excuse to ditch it early. My Verizon contract doesn't end until November, but at that point I'm looking at leaving and heading to T-Mobile. If I end up having to get a new phone, I'd like to just get an S4 instead of a pathetic temporary one - that way when I switch to T-Mobile, I've already got my phone. I've done some searching and it looks like the Verizon S III can run on T-Mobile, but I found nothing for the S4...
Would it be possible for the T-Mobile variant of the Galaxy S4 to work on Verizon's network? Network speed isn't an issue for me.
No, this is a gsm phone, it will not work on cdma networks

Verizon S4 has secondary radio that works with GSM. That's why it works on T-Mobile and AT&T. T-Mobile does not have secondary radio let alone ones that supports CDMA. This is why T-Mobile will never work on Verizon network.

Thanks for that extra info and a reason why. I think I'm going to let the phone sit for a few days while I contemplate whether or not to drop Verizon with an ETF and head to T-MO or not... It's tempting.
I just took my Verizon Note 2 over to T-Mobile a week ago. I'm in the Denver Metro and had nothing but problems with the Verizon phone on the network. I popped in a T-M SIM card and while voice was fine, at home I jumped back and forth between edge and H+ and at work, I was stuck with nothing but edge. I called and was told that not all the T-M towers are setup to take non-TM branded phones at this point. Long story short, I went and got a T-M S4 and it's working fine, although the T-M coverage leaves a bit to be desired for a large metro area. Hopefully LTE, when the switch gets thrown here, will help some.
The Verizon Note 2 doesn't support AWS band. Thats why it's jumping between E and H+ all the time. The H+ is actually 1900mhz that it's locking on to. You need a phone that has the 1700mhz AWS band to connect to H+ reliably.

Question people..need help. Just got Internation N7100 Note 2..want TMo LTE

So I just got a International Note 2 from a friend who was in Germany. I see its a N7100 and stated to not work on LTE. That really kills me. I wanted it bad. So now I am stuck with a issue...can I get Tmo 4g lte on this any way possible?
Can I flash the T889 factory image over this phone which would get me the tmobile factory. Would that enable it. I mean the phone has to have the radio inside to work on the LTE right but you just have to get to it some way. Or is it really a hardware adjustment that I cannot do anything about?

I believe that the n7100 only supports hspa on tmobile. Not lte.

If I helped you hit that Thanks button!
The baseband hardware in the N7100 is significantly different from the one in the T889/I317/N7105 variants. (Intel vs Qualcomm)
Don't bother with the T-Mobile USA images, they won't work on the N7100 without some modifications. Unless you use Wi-Fi calling, I'd say you're better off with international versions anyway.

[Q] I747 only getting edge on Cricket -- Plz help

OK so I have a Galaxy Grand Prime (locked to Cricket) that gets 3+ bars LTE at my home. I recently got an AT&T (locked to AT&T) Galaxy S3 (I747) off of eBay to use on Cricket. Since both AT&T and Cricket both use AT&T's LTE network I expected it to work without a problem. However when I put the Cricket SIM in the S3 I can only get 2G EDGE network. I have tried different APNs, network modes, even a couple custom roms. I have no idea what the problem might be.
Any help would be much appreciated
What bootloader and modem are on the phone? Not sure if either of those things will keep you on edge.

Flash Verizon Firmware on AT&T Phone

I'm looking to bring an unlocked AT&T Note 5 over to use on VZ.
Is it possible to flash VZ firmware and have the phone work just as if it was a VZ to begin with (and receive 3g data, text, and calls) or is that something that's hardware related and flashing the new firmware won't help?
I've found this information, so I know the consequences of using an AT&T phone on VZ normally...
"If you're hoping to use your unlocked AT&T phone on T-Mobile, you should have no problems. Both carriers run their networks on GSM technology, so once your phone is unlocked, just pop in your new T-Mobile SIM card and you'll be up and running. AT&T and T-Mobile both use Band 4 for their LTE service, so 4G LTE devices should be able to access the network without issue.
Although Verizon uses the CDMA standard and not GSM, you still may be able to use your AT&T 4G LTE device on Verizon's LTE network, as they both run on the same spectrum; so LTE data should, theoretically, work fine. However, it's unlikely that you will be able to make or receive calls and texts, or access data over Verizon's 3G service.
Sprint is also a CDMA carrier, but runs its LTE network on a different band of spectrum than T-Mobile, AT&T and Verizon; it may accept selected AT&T devices on its plans, but you'll need to check first."
I'm curious, because I rooted an flashed the unlocked software on a friends VZ's s7 for use on Republic wireless, so I know this sort of thing can be done. I'm just not knowledgeable about the differences in these 2 scenarios.
Thanks so much in advance!
You can't flash any firmware on the AT&T note 5 other than official AT&T note 5 firmware because the bootloader is locked. I'm not sure about the part of using this Note 5 on Verizon.

SIM unlocked T-Mobile Z2 Force - on Verizon?

There are a ton of entries on XDA about sim unlocking the T-Mobile and Sprint versions of the Z2 force, but none of them confirm once unlocked if they've used it on Verizon.
T-Mobile's page confirms their version utilizes bands 2,4 and 13 - all of which are Verizon's LTE bands.
Can anyone confirm?
I'm looking to buy this to replace a work phone on Verizon. My personal account is with T-Mobile, so would be very nice if I could just flip sims whenever I'd like. Appreciate in advance the responses!
(unlock T-Mobile bootloader, sim unlock, root and put a custom rom with safety net passes)
then type this on google and try.

If you can't activate the cdma bands, you will have no 3g connection.
Oh if this works I would be so happy to switch back to VZW. Anyone attempted it yet?
I'm interested in knowing if anyone tried this too
I’m too chicken to mess with anything not official from xda on my daily driver. I’m sucking it up and waiting out the period for the device unlock app to ‘officially’ sim unlock and try. When that day comes, I’ll post here.
I think it’s ignorant having to wait for a sim unlock for a phone you bought outright.

Eagerly awaiting news on this - why is there a waiting period on the sim unlock? How longs is that period? I'm about to head out to Tmobile store and buy me one too.
Verizon's LTE band 13 is exclusive to the Verizon model unfortunately. I wish it wasn't so you could use a bootloader unlocked Sprint or T-Mobile edition on Verizon. I did that with the Google Pixel - used the universal one on Verizon. I just got used to having an unrooted phone with the z2 Force. I switched to blokada after many years of always using ad away. I think most all ad blockers on unrooted phones are VPN based so it lags WiFi and mobile data a little but that's what you get to work with if you want the best moto phone running on Verizon.

Could you provide your source of information on that? T-Mobile's listing of the Z2 Force lists band 13 LTE capability, and multiple sources say that the Sprint variant has band 13 too. I am just about to pull the trigger on a Z2 Force variant that is bootloader unlockable, but whichever carrier version I get has to work with Straight Talk Verizon.
I'm seeing the sprint one listed as having band 13 now everywhere actually. My bad. I don't recall seeing that back when i got it and was shopping around. Let me know if the Sprint one works for you on vz because i miss having a a rooted phone.
The only different thing on the US phone's is the oem partition. Everything else hardware and software are very similar to the point I want to say identical. (Obviously, some slight changes in /system and stuff but that's with the territory of using OEM ROMs). I have flashed a T-Mobile flashall and it worked. I flashed back to Sprint shortly after. I did it for science.
So in short, will am unlocked T-mobile Moto Z2 work on the Verizon network with a sim swap? Or does it require a root or the bootloader thing that was mentioned, I haven't done either one as I am content with factory.
So, what's the verdict? Will unlocked T-Mobile Z2 force work with Verizon?
Most likely will not work. T-Mobile variant is GSM and most likely doesn't have the CDMA bands on it or programmed into it. Only thing you can try is flash Verizon firmware and see if it works. 99% chance T-mobile firmware will not work, Verizon firmware has about a 40% chance of working. If you don't have the device, I'd suggest not investing as no one has tried it.
I tried the Verizon flash all on my TMobile z2. Didn't work.lost baseband.
The flash all looked as if everything flashed properly...but when it finished and rebooted it still had tmo splash screen. So I don't know if it really did it.
If it's worth any thing my Verizon Sim in my tmo z2 gets great data...just no calls/messages
I have an unlocked Sprint variant that I flashed to Verizon and use with Straight talk Verizon. The only issue is that so far whenever an update comes in I have to back up all the things I want to save and flash the updated flashall, because the automatic updater just keeps on failing. I don't know if this matters, but I'm bootloader unlocked (had to for sim unlock) but without TWRP or root. It's possible that if I would try relocking the bootloader that the automatic update process would work. I briefly had a Mint sim in there (T-mobile) and everything seemed to work. I didn't really try things out with the Sprint rom, but as I remember everything worked, I just didn't like the icon style plus always having a notification saying something about a non Sprint sim card

Was it officially unlocked or was a modified file flashed to your phone? If you had a third party service unlock, then the hash check for that partition is incorrect and that's why updates fail.
I had a third party unlock it. Actually, it was the guy that people on this forum have talked about.
Will this work on Verizon? My tmo z2 was unlocked by TMobile not a third party
No it doesn't work... You can get data but that's it..

Hi- I am wondering about being able to buy a new-in-the-box z2 Force that was originally sold for Sprint, and being able to flash the T-mobile firmware to it for use with them. Is this possible? I have done this for Galaxy S8/S9 phones, but there is a deal right now where I can get this phone with 2 of the mods for dirt cheap, but it won't really matter if I can't do the conversion. Any advice?
