Like most Droid 3 owners I'm sure, I'm tired of paying ~$105 a month for cellphone service through Verizon that I could be paying ~$70 a month for through T-Mobile.
I've read the other thread here associated with unlocking the GSM portion of the Droid 3, but a lot of it seems to be shrouded in maybes and varied successes with a limited pool of test devices to draw on.
From what I gather thus far, the following is true:
- You can unlock the GSM capability of the Droid 3
- You can operate it on T-Mobile
- If you do, you will only get "Edge" connection speeds - No T-Mobile HSPA+ or 3G speeds. "Edge" only, at 512 kb or something like that.
Can anyone confirm this? Is there a way to get a Droid 3 to operate on T-Mobile's network at full speed?
Is there a more reliable and easier to use method to convert a stock VZW Droid 3 to something operable on T-Mobile?
Thanks in advance to anyone who can accurately answer these questions.
The only thing I've seen that works is using the xt883 Chinese ROM and it only gets edge. Edge is fine for me, but I want a better ROM with access to Android market.
Im still learning how this device works; I just installed Safestrap and tried to flash the GSM CM7 ROM today, to no avail. I flashed a custom ROM on my Droid 2 last year, but it's been a while on the G2x which isn't as locked down.
I flashed the CM7 GSM ROM on the safe mode partition, thinking that was how to do it, but I got an error trying to back anything up because /system wouldn't back up. Then when I flashed the ROM it wouldn't boot. Im wondering if I was supposed to flash the ordinary CDMA CM7 first, then use the GSM one, since it's named 3gedit.zip. I haven't tried that yet though, and the fact that /system isn't backing up worries me. I didn't create a partition on internal with Safestrap, but I flashed the GSM CM7 ROM from coreless in safe mode and it wouldn't boot. Got back to non-safe mode and my stock ROM was fine, but I still want to see a good back up :-/
Any ideas from more experienced users would be great. I'm pretty much a blind guinea pig right now lol. I just really want to see CM7 on this D3, and have it work on T-Mobile so I can retire my G2x for a little while.
Thanks in advance

Tutorial
note: This is not tied to any specific rom, it is not using the chinese rom it is simply taking the radio off the chinese rom which is all we need. It hasn't changed anything to me in user space that I have noticed.
I would recommend unlocking, rooting, flashing the radio, and editing the build.prop.
1. Unlock or online sim card unlock code seller but less reliable.
a) Meet the following requirements:
* Must be a Verizon Wireless customer.
* The phone being unlocked must be active on a Verizon Wireless line of service.
* The line of service must be active at least 60 days.
* The line of service must be in good standing for the past 60 days.
* Only one SIM Unlock per line every 10 months.
b) If you don't meet one or more of the above requirements, call anyway. You may still get lucky.
Call 1-800-711-8300 (Verizon Global Support) and ask the representative for a SIM unlock. Occasionally a representative may not know exactly what you are referring to; make sure you are not transferred to a different department. You are in the right place. Explain that they should have a walkthrough on how to do this, and that it allows for the use of local, non-Verizon SIM cards while traveling abroad.
c) Insert a foreign SIM into the SIM card slot on the side of your phone and then enter unlock code.

All you have to do is flash the radio.img from SOLANA_SLNCT-57.1.60_Fastboot in fastboot mode
Code:
moto-fastboot flash radio radio.img
then add the following lines to the build.prop
Code:
persist.ril.rssi.enable.param6 = 1
persist.ril.baudrate=230400
I can confirm this works with an AT&T sim in an unlocked phone, tested with stock and liberty 2.0.

I have called out, received a call and a text, I have checked my account information with the tmobile app on edge. I have been led to believe that its hardware that tmobile can only do edge since they use some non standard bands.

Even if you go through all of that you I'll still have only EDGE because our radios don't use the 700 MHz. Just sell it and get a phone for T-Mobile.

Thanks for replying. That's where I wound up going on my own because I was trying to use his CM7 last night. Can't seem to get it to flash though. Backing up with Safestrap isn't working either...getting an error because /system won't backup for some reason.
I think I'm gonna flash everything back to stock, uninstall Safestrap, and try the above from the beginning. I'd like to see if I can at least get edge and below on T-Mobile using a US ROM.
Thanks again!

So, I have a couple of lines on VZW, but they are all used by family members on my account, and I don't have a VZW SIM. The guy who sold me the phone said he already unlocked it, and I believe him, but is the SIM an issue and is there any way to know if the phone is still unlocked? Can an unlock be undone after wiping internal sd?
I'm asking because I think I can just not worry about that step, but I want to double check. I put it back to stock 2.3.4, now showing 5.6.890 xt862 instead of whatever the xt883 was. I did this to get rid of the previous owner's Google account. Edge, calling and text were working on T-Mo when I bought the D3 a few days ago. When I put my SIM in now, however, and change it to GSM/UMTS mode, there are no operators available when I tap on the list and of course it doesn't work yet. I understand this is due to putting it back on stock lol, but I'm gonna go ahead and try flashing the radio and seeing what happens.
It's already rooted using zergrush. Has safestrap and I can boot into it by rebooting/pressing menu, but my /system folder won't back up. That's the only sign that something is wrong other than the fact that no ROMs will flash in safe mode. I've already left comments on Hash's site, so I'm waiting over there too. Figured I'd pop in here again real quick
Thanks.
UPDATE (from the other forum):
My Droid 3 is working on T-Mobile for voice and text. This is exactly what I wanted. Got some great in-depth help on this one, especially from @tspx23. Thanks a ton! This will be my daily driver now until we switch to VZW, at which point this will turn into a back up, unless I fail to find something else worth a contract at that point lol.
I might write a guide later on if anyone wants it. The process is easier than it seems, as long as you have it in plain english lol.
Thanks to anyone who contributed to this!
Is it possible to mix this with a current rom instead of flashing a random Chinese one, like infuse with cm7 or liberty?
Tmo has horrible coverage and awful customer service. Cs is all nice to you but lies about everything constantly. They did nothing but screw me. That's the whole reason I'm on verizon now. At least now I have coverage and won't be lied to whether or not I have it, or be told to get wifi and then u can make calls since u don't have service.
Sent from my DROID3 using xda premium
I don't know of anyway besides a sim card to check if its unlocked and I am not sure a verizon one would ask for the sim unlock code even if it was locked but sim cards can be really cheap. If your phone was unlocked that will never be undone, if it was working on tmobile before you reverted to stock then it is unlocked, it would not have worked using tmobile otherwise.
are you using the latest version of safestrap, he released a bugfix version pretty recently? Could you be more descriptive of what you did while in safestrap?
It is not rom specific as far as I know, I am just using the stock one.
@Darksurf, I agree. I never had them but before I moved they didn't cover my old town. Verizon may be expensive but at least they tell you they will rape you at front and explain all charges.

you can also try with at&t in full3g. As they have the same bands the d3 has
Enviado desde mi DROID3 usando Tapatalk
I will see tomorrow if this works with ICS
Radio and build prop edit
I'm staying on T-Mo till they go under. They are cheap and I have unlimited Edge, which is all I can get on this phone anyway lol. Only ten bucks a month for data, since I have an older package from before they tried to hike their rates.
My D3 is having some issues after I reboot, and sometimes just randomly, it will lose all signal and tell me that my preferred operator cannot be found or error connecting. I have been just rebooting and sometimes wiggling my SIM around to see if it fixes, and it does.
Only other thing that is a little weird is my phone thinks it's an xt883, even though I'm on the stock VZW ROM. I'm wondering if this is causing some issues that I'm not qualified to really diagnose lol. Usually after I reboot, I have some of my google apps' names in Chinese, but I'm not sure if that is from radio.img, new build.prop, or from changing my bloatware to .bak.
Also, be advised that if you remove bloat, conversations.apk breaks incoming text if it isn't seen by the system. I added .bak to the end of it and could send texts to my wife, but couldn't get any messages. I changed it back and texting works fine. I use Chomp SMS, but that didn't seem to matter.
Have fun
P/S: also, when choosing operators in settings, you have the option for T-Mobile 2G, AT&T 2G or 3G. Just to confirm ;-) probably because AT&T's 3G bands are the international standard, right?
when you flashed the stock rom back onto it did you delete the /system partition and do a factory reset on your device before you did it?

I'd love to see someone put these mods into a ROM, but I'm not sure if any of it is compatible with existing ROMs. I also accomplished this on stock. When I get around to flashing CM7 again (or trying to at least lol), I'll post about how it goes.
I'm thinking that when I wiped my phone, the unlock remained but the radio.img that was on the Chinese ROM was undone or lost. Flashing it was easy though, using cmd mentioned earlier in this thread. I just needed help figuring out how to set it up, since I'm a noob at command line lol.
After that, I downloaded adb and tried to use other commands I've found (which claimed to work, but didn't for me somehow) to change out the build.prop. This failure was likely my fault lol but I found it easier to just use Root Browser lite to back up my original build.prop then replace it with the modified one.
I figure that if my SIM doesn't work after flashing some other ROM, I'll just try the two main steps again and see if it works then. If anyone really wants to do this, it isn't too hard or not worth it in my mind. I also figure this phone will be relevant enough for a while longer, considering I am cool with Edge speeds, I certainly won't mind being stuck with VZW's 3G whenever we change over. I am in no hurry to get LTE battery suck or bulkiness either. I'll wait for a little more refining to be done on that end before I upgrade from this phone
I am interested in making the phone compatible on T-Mobile / ATT by flashing XT883 radio. I have one question: Will the "unlocking" turn the phone completely GSM phone so it can no longer work on CDMA network?
Thanks.
Probably until you flash the Verizon ROM back I would assume.
Sent from my XT862 using XDA App
No. XT883 is also CDMA compatible, so the ability to use CDMA should stay. You might need to do *228 though.
You unlock the phone via carrier unlock code, e.g. they give you a code via email or over the phone allowing your gsm functions to work with foreign sim cards (other than the one they come with). After getting the unlock code and flashing the xt883 radio.img (and changing/replacing your build.prop) you can still choose to use cdma. Flashing this radio (which I'm currently using on T-Mobile) doesn't make your phone incompatible with cdma and is reversible. You would simply have to flash the original radio.img and change back your build.prop, or just flash a regular cdma ROM. I plan to do this some time next year if/when T-Mobile goes under and my wife and I switch to Verizon. In the mean time, I only get edge on T-Mobile (using it on AT&T will get 3g), but I have cheap and unlimited data (legacy data plan $10) and a great phone with keyboard. I'm using the stock ROM, rooted, but will eventually try CM7 with the gsm tweak. I will likely have to reflash the xt883 radio.img and change my build.prop (I think).

Hi Everyone,
I'm not sure how to try this out, since I'm not in the US, and that RadioComm doesn't work for my Droid 4 (it's been upgraded to ICS)
1) Install latest Motorola drivers and RadioComm
2) Launch RadioComm
3) When it RadioComm launches, Click Main -> MA -> Common -> MDM 6x00
4) Click Settings -> USB -> PST USB
5) Click on FTM Common 1
6) Connect the phone to the PC and wait for it to go green
7) Under NVAccess, find the following values:
4870, NV_GSM_850_CARRIER_SUPPRESSION_I
4871, NV_GSM_DCS_CARRIER_SUPPRESSION_I
4872, NV_GSM_1900_CARRIER_SUPPRESSION_I
8) For each value, press Read, then replace all of the numbers with 0. Once done, press write. Repeat for all 3 values/
Let me know if this works!
Again, I mentioned a problem with RadioComm. I'm using Windows 8 x64, RadioComm worked fine with my Bionic on GB, maybe it's an ICS thing, maybe I need newer drivers, etc... Please let me know if this works!
I was able to get this going on my Droid Bionic (which also had a corrupted IMEI number) so if you want to see that post, view it here :

This looks awesome -- I saw your post in the Bionic forum. I was curious if this worked for anyone in the states on T-Mobile? I was looking to get a Droid 4 and use it on Straight Talk. Currently have an Epic, but loved my OG Droid. 3G is fine enough for me -- just curious if anyone is also able to get MMS working as well, along with APN settings?
What version of RadioComm do you recommend? I've tried 11.9.0 and I get the error when I try to open it:
"Error in getting the pointer to CommP2K and/or CommQC. Error number: Exception of type 'System.Exception' was thrown."
If you can help me get past this error, I'd love to try this out...

Awesome, I'll give it a shot when I get home. Out of curiosity -- I'm assuming this is similar to QPST. If I bork the modem, I should be able to go back to a prior group of settings, right?
SIM Card should be coming in on Saturday or Monday -- so should be able to get some news to everyone by then.

Still trying to figure it out... I don't think we have a solution just yet.
I'm a developer outside of all of this (C# primarily these days, but have an extensive background in C/C++) -- and I've flashed phones to cricket with QPST -- so maybe I can help you guys out with this. If you're up for discussing any background that might catch me up to speed on this (already have my phone), would be up for trying to help break into it and enable this. Just send me a PM if you're up for this. Thank you!
Hey all,
I've only used this program for a little bit but I was able to change the values to what the OP suggested however, I used the Motorola Factory USB cable. I couldn't get the program to recognize my phone w/o it.

So, you updated it with that -- were you successful and does GSM now work in the US?
Did anything change?
Phone doesn't make calls now
I followed the steps above
Radio Comm v11.12.2
Motorola drivers 2.2.28
Whatever data card drivers came with radiocomm
This did not allow me to see t-mobile or at&t here in the states.
So, random question/thought... If we find another modem with similar chip in another phone -- say on AT&T -- would we be able to read some of these fields and stuff out -- and then push it into our modem?
it would be great if we can set the phone to just swap SIM cards very easily, especially in the US

Hmm, might be an idea. I don't think that there were many AT&T phones with this capability though. My idea is to compare an XT910 vs an XT912, since that was a worldwide release.
Best idea, get an XT910, put your SIM into it, grab a full radio dump, then put your SIM into the XT912 that doesn't work and grab another full radio dump and compare the two.
You'd need an internation XT910, since AT&T didn't ship them down there, but that would be a great starting place...

Only thing is that I'd have to go out of my way to do that and spend even more money. I just dropped some on the Droid 4 for an off-contract phone. I wonder if there's any way we could ping some of the other forums, i.e. the Razr and see if anyone can potentially get us full-reads, so that way we could compare/diff them?
In addition -- I wonder if it's possible (probably a long-shot) to potentially order a SIM card or something from another carrier in Europe or somewhere outside the US and get it into the phone, but then have it "added" or "roaming" on a US network or something -- if that might provide a workaround?
Just trying to take stabs at it. I figure I'll hold onto the D4 for another month and see if we have any exciting developments -- and if not -- just push it to Swappa.
So i could use this to unlock the radio for overseas teleco use?

Not sure what you a proposing in your second paragraph. I have a UK SIM card, and when I plug it in two other phones (Samsung Renown, a CMDA/GSM basic phone) and a Motorola quad-band GSM phone, it works fine in the US. When I move the SIM into my Droid 4, no signal, although it sometimes gives the Unrecognized SIM message. So it's not a matter of non-US sims.

I get the unrecognized SIM message also. That doesn't affect the phone one bit though, since I just press okay to the message and the phone connects to my carrier. Is your carrier one with a Verizon roaming agreement?

I recently moved from the midwest to the east coast. Before my move I had fantastic coverage in places VZW didn't even advertise as covered. I visited my new home in PA several times, and had great service the whole time. Skip forward to a month ago, I moved permanently to PA, and since about a week after getting here I have had nothing but trouble. I will often lose service altogether, but most of the time I have 3-4 bars of 4G.... but no calling. I get "Mobile Network Not Available" and incoming calls simply ring until voicemail on their end, with no indication I'm getting a call at all on my end.
I have reflashed radios, done a factory restore of the ROM, swapped SIM cards with my wife's phone (Droid Ultra, stock NO issues at ALL) and nothing seems to fix the problem. I'm not sure what to do next. Does anyone have any ideas?
Edit: imei.info shows my phone's IMEI as a Droid Bionic.... I have never owned a Bionic?

Use RSD Lite to flash the entire VZW 4.4.2 SBF, which includes modem, and all partitions. See if your issue persists. If solved, then try flashing Kryptonite and see if the problem is still present.
Ignore the data from imei.info - their database is less than perfect.

I tried a new SIM card (at Verizon's request) and no dice. I haven't tried an SBF yet, although I did flash the new version of Kryptonite's ROM. If I sbf will I lose disabled write protection?

Yes you will absolutely lose wp-off. Only other option is to flash entire 4.4 sbf, repeat the root/wp-off exploit, then install safestrap and flash the kryptonite rom again.
Alternatively, you might try flashing just the radio. I suggest asking in ikryptonite's thread. I believe he has the proper radio available to flash via fastboot.
Good luck
I bit the bullet and just SBFd anyway, and still not fixed.
Is it a hardware issue then?

Most likely. Hope you are still under warranty.
Please remember to hit the "THANKS" button under any posts that have helped you or answered your questions.
I cannot use the Mobile Hotspot function to the internet after my droid turbo upgraded to 5.1 Lolipop.
My PC always show no internet access. I have tried the factory reset but still cannot fix the problem.
Does anyone have same issue???
Thanks
Do you have tethering as part of your plan? Android 5.1 has a built-in check for that.

No, i am working oversea, so used the local sim card to share wifi before.
How can i cancel the built-in check?
Mine is working fine, on 5.1

Assuming your response was that: you are on a plan without mobile hotspot/tethering allowed.
AFAIK there isnt a way to activate it on stock 5.1 and there is no way to turn that built-in check off.
Unless you find a way to root the 5.1 Droid Turbo. Which, by all means, find that way and you'll make a lot of people happy.
Sooo there also isn't a known way to go back to 4.4.4 (which has various root options).... and here's the big band-aid rip...
You cannot achieve what you want with the phone you have running the operating system version it's on with the non-mobile hotspot plan.
Find a way to get a 4.4.4 Turbo so you can root it (sounds like a challenge being overseas) or just hope that someone finds a new hole in the Verizon/Moto/5.1 security.
EDIT:
If you never modified your Turbo while on 4.4.4 and were able to tether, even though its not apart of your plan... then I have no clue how you did what you did/what to tell you now.
Also my knowledge extends to the "Verizon Droid Turbo"... the "local sim" means I may have written all of this for nothing.

Thanks. Because the wifi hotspot is worked for the same sim card during android 4.4.4. Just doesn't work after i upgraded.
I use my Droid Turbo in Mexico with Telcel. My Hotspot worked before and after the 5.1 Update. One thing I do remember is that it didn't work right after the update. For maybe the first 6 hours the option for Hotspot was greyed out and I could not move the slider. The next day for whatever reason, it worked and continues to work just fine.
Hope that helps,
Chad

I am contemplating purchase of one of these phones, and tried entering some of their IMEI numbers in the imei checker at https://www.t-mobile.com/resources/bring-your-own-phone , and was shocked to find they are ALL described as "Incompatible".
This is a bit confusing after the articles saying the AT&T and Verizon versions would not work after Jan 2021 but that the T-Mobile version would continue working. I tried looking for a later article saying that support for the T-Mobile version this model was being cancelled but could not find any such announcement.
Is that IMEI checker correct? Or is it because the samples I checked may not have gotten the last modem update installed from T-Mobile?
Is anyone still using this phone (specifically the T variant) on T-Mobile in USA? I'm assuming that last update will be important, but does this still work once it is installed?
If yes to the above, do phone calls work as VoLTE, or is it doing the fallback to 2G?
I've also seen threads about enabling more LTE bands, has anyone done that on this phone? In particular is it possible to add support for B71 (600MHz), or is this radio hardware just too old to allow that?
Thanks much, I would really like to know whether I can use this phone or if I would need to find a different model.
https://swappa.com/blog/3g-network-shutdown/ Your phone is fine.
SM-N910T with 2ETI1 OTA modem update works fine. 4g/LTE Data, WiFi Calling works. Does not drop out of 4G/LTE for voice. SM-N910V w/ MODestROM v11 (6.01 TW-based N910VVRU2CQI2 ) w/ a vzw 2CTI baseband update, has working 4gLTE data, but no WiFi Calling, or VoLTE (falls back to 2g, but I still have 2g coverage here, so it's usable, if not optimum. Here's the thing: on the VZW phone, if I set the the salescode to TMB, suddenly VoLTE works, but the Setup pages/menus/statusbar are screwed up, so it's not really useable. Here's where it gets REAL interesteing. On a VZW phone w/ VZW 2CTI1 baseband, & VZW BL, flashed with a custom TMB ROM (trltetmo_N910TUVU2EQI2_Stock_Deodexed, debloated, but still TW), EVERYTHING works. But it's not stable, it periodically loses 4g/lte. What it tells me is that the VZW h/w is NOT THE PROBLEM. I've been at this all day, everyday since VZW turned off CDMA on 01/01/23 and killed my service here. Be warned: If you go down this path, you're gonna be mostly on your own. A LOT of dead links, 'retired' devs, etc. Everyone except you, me, and three other people here have long since moved on from this awesome phone. I'll help you if I can. I bought an SM-N910T , but the damn usb port is dead. Already changed the charging board, not the problem. It's the mobo. If I could identify the usb chip (if it's not the 805 itself, I'd change it. So I have a phone with no adb that I can't unlock/root. I'd much rather get my VZW phone fully working on TMB, since I'm heavily invested in the MODestROM. Haven't given up yet. But search my posts, you'll hear the deafening silence, lol.
Seeing this forum has so little activity, on 1/21 I ended up getting a used Moto E6 (XT-2005-3 is a tmobile aka carrier unlocked MetroPCS version). While overall this is not as nice a device and has fewer features than Note 4, it does cover what for me are the essentials - removable battery, SD card slot, support for 5.8GHz wifi. Best of all, it supports B71 which will be helpful for, well, making phone calls!
I still ponder someday getting one of these as a hobby device, but that would be second place to the E6 for use as a phone, and won't be for a couple more months yet (too many expensive household issues are taking their toll on my "toy" budget right now).

Thank you, this was the part I needed to find out. With that in place, the only thing missing would be the B71 coverage but the E6 is already in place for that.
Re your Verizon adventures, I have no experience with any of that. What I read about T-Mobile dropping support for the verizon version in the last network update is all I know, and I don't have the skills to dispute what they say there. The best I could do is offer some links to threads on this forum but on double checking them it seems you've already been there and got no answers.
The only thing I see that might help you with that is if you could update just the t-mobile modem without disturbing the verizon bootloader. I see you tried that but it didn't stick when using Odin. I don't know if it would be any different using SmartSwitch that seemed to work for MarineWonder as he posted at https://forum.xda-developers.com/t/...pgrade-on-jan-29th-2021.4224237/post-87464609 ?
Then again he may have been putting it on a t-mobile phone rather than mixing with the verizon bootloader so who knows?
My guess since it has been so problematic for you on the verizon phone is that you may need to only use a tmobile phone since that may be the only way to get the last t-mobile modem update. Bummer that the one you bought has a dead usb port. How are you charging it? Is there any chance you could return it to the seller since it came pre-broken? Then put the refund money toward another, hopefully working, tmobile phone? And would that MODestROM work on a non-verizon phone?
The only other thought I had is there are apps to connect to ADB over wifi. Sadly most of these need root. The ones that don't, seem to need at least once using a usb connection to do the "adb tcpip 5555" command to set it all up. . . . how annoying that it is all so circular!
There is also https://telnetd.en.aptoide.com/app?store_name=apps&app_id=59202144 , maybe a telnet connection could do the "adb tcpip 5555" command instead of using the USB connection? Sadly the documentation (at https://waxrain.com/docs/010.html ) appears to be written in Chinese, and I never had much luck with google translate.
The N910T still supports VoLte.. It is still compatible with cellular networks.
