T-Mobile Band 12 Access is working - Project Fi

Hi Everybody,
this is my first post, if it's been mentioned somewhere else on this forum, than I apologize about it.
I got my nice shiny Nexus 5X last week and I have immediately realized, it does not connect to B12 on T-Mobile. I saved some network logs on My old Motorola Nexus 6 and on my new 5X and it was clearly blocked. This phone should work on B12 right out of the box, therefore the immediate OTA update was suspicious for me. I was right, it was not only a monthly security patch, they have also "downgraded" the base band for us, just because a FCC approval is missing (911 access on T-Mobile's VoLTE), however on Project Fi we have E911... We still should have a Project Fi specific firmware until FCC approves T-Mobile's application...
I have downloaded the very first official ROM (MDA89E) and extracted the radio and flashed with ADB on my device. It is working flawlessly with the latest "I" firmware and MOST IMPORTANTLY I DO HAVE B12 on my phone.
If you'd like to try it, please do it. Remember, I'm not responsible for any damages, flash it if you exactly know what you are doing...
The radio(baseband) version what I flashed on the latest MDB08I is: M8994F-2.6.22.0.56
If it's worked for you, than do not hesitate to hit the "Thanks" button
Update on 12/07/2015:
The New MMB29K 6.0.1 update has a new radio, which is finally T-Mobile B12 compatible. (radio-bullhead-m8994f-2.6.30.0.68) Looks like Google and T-Mobile silently "solved" the issue. There is still no official announcement...

Just did this and got Band 12.
Thanks!

Did you use fastboot to flash the radio.img file?

yes I did (fastboot flash radio radionamexxxxxxx.img ) For example I renamed the radio file to "radio_old.img" than the right command will be:
fastboot flash radio radio_old.img
you have to run the command prompt with administration right and most importantly you must have an UNLOCKED bootloader

Thanks! Nice discovery!
Will B12 work even when I'm just a normal TMobile user or is this limited to Project Fi subscribers?

It's not limited. Since Marshmallow the firmware supposed to be universal for everyone in the same market.
It will work just fine for T-Mobile users, I'm 100% sure.

Wait, so you're saying it has Band 12 out of the box, but that first OTA update you get after starting it up eliminates it? I knew I should not have installed that.

Correct, and you do not even have chance to eliminate it. At the very first power on cycle the system will install it once you set up your WiFi network.... It will immediately download this "update"

It immediately downloads it, but it does not install it until you tell it to, at least in my case.

I just flashed the radio and the LTE discovery was telling me I'm on B4. I covered the phone to lower the reception and it switched over to B12. Thanks!

I don't suppose someone can upload a flashable zip for this radio? I'm at work in a concrete building and would really really like to see if I will benefit from this.

Thank you!

I can not upload it anywhere at this moment. The max size what I can upload to XDA is 20MB
Please extract both files, than open it again in 7Zip or similar and you will have the radio image file. (XDA does not allow to upload files with "strange" extensions)
I hope it helps

I must be doing something wrong, I still get a bad file error. I'm using esfile with 7zip extension. I cannot do this on my work comp. its locked down pretty good..
Thank you for all your efforts, but I'll wait till I get home and flash via fastboot .

Slightly off topic, but under Wireless & Networks → More... → Cellular networks, do you have the option of "Enhanced 4G LTE Mode" either before or after doing the downgrade to the radio firmware? Trying to figure out if the absence of this option is an issue with the ROM, radio firmware, or my carrier.

I have good B4 reception but I can kick it over to B12 every now and then.

I do not have this option , I have not seen it earlier. I checked my wife's 5X, which is stock and updated to the latest firmware and There is no "Enchanced 4G LTE Mode" as well.
Forgot to mention: We are on Project Fi

Progress: Boost Mobile Moto E4

Hello, I'm new
I'm not sure if this is the right place, I felt a discussion area was an okay place to share and discuss my findings
I'm working with the Boost Mobile Motorola E4, the contents to this thread will relate solely to the Boost E4
Bootloader Unlocking
Unlocking the E4's bootloader was very simple through Motorola's website, it is for certain unlocked
After unlocking the bootloader I got the bad key screen but in my experience that's normal
You can verify that your bootloader is unlocked by using fastboot or checking the Developer Options
Rooting
Other people claim to have success with it, I have not yet had that success Just flash Magisk 13.1 after flashing the verity zip, don't bother with anything else, root will work first try. If you tried another root method, you will have to restore with the method in post #2 before it will work without giving the error.
After flashing the superuser zip and the verity zip, I wasn't led to a successful root I instead downloaded SuperSU-v2.82-201705271822 and flashed that after the verity zip and i was able to reach home menu
I tried flashing Chainfire's SuperSU zip but the device stuck at the boost mobile logo, I will try again after I can get back to stock and do the processes over again and find a way to have 100% success each time Downloaded a new version SuperSU-v2.82-201705271822 as noted above and i was able to fully boot
The issue now is that SuperSU app isnt detecting root but Terminal is gaining root, I'm going to try reinstalling app from the market. I got the SU Binary Occupied error, going to try to downgrade it to 2.79 and see how that goes. It didn't work for me, now it says improperly installed.. Going to try something else. It's 1:55AM August second, taking a small break from the root, at least I got other things figured out for now.

Sprint 7.1.1 stock RSD file: https://androidfilehost.com/?fid=673368273298975628
-update- I added the stock RSD file to the list, going to be doing some pulls of stock files for us to work with when I can.
I'm going to try to collect as much information as I can about this device and provide as much detail as possible

NOTE: The below IS NOT Boost Mobile stock, it's sprint will update when I figure out Boost Stock
The sprint stock does fully work with the Boost Mobile device, LTE/data services seems to not work until you do a Factory Reset (in settings). ##72786# didn't work. It is now working for me fully after the factory reset from settings. The boost apps automatically install after the factory reset and after the celluar setup on first boot.. My Boost, etc.
After a few times of flashing and re-setup I've ended up with HFA error 701 which asks me to contact service provider to configure the device for service. Fixed by turning phone off for 20 minutes to an hour and the activation processed correctly.
If your experience differs, let us know!

Download the Sprint firmware file: https://androidfilehost.com/?fid=673368273298975628
Rename the zip to sperry.zip, the reason for this is to avoid the long file name error in RSD in some locations
Let the flashing process complete
Some people reported RSD not working in Windows 10, this is not fully true, install all moto and android drivers and it will show up fine as seen in below image

I have the Boost Mobile variant.

Is there anyone with the Boost Mobile variant that made a working system and boot backup? If so, could you please upload it for me? Mine got corrupted somehow and won't restore.

@amarc78 You should be able to use the Sprint firmware posted by zoofie666 - Boost is Sprint's prepaid brand.
The weirdness with the activation on Sprint/Boost seems to be normal, because I had trouble with two phones recently. The first was a retail unlocked e4 (to be used on Sprint), done before rooting, and activated at a Sprint corporate store last week by a rep who had trouble. The second phone was a retail unlocked Moto g4 Play (also to be used on Sprint), that I rooted first, got the SIM and back-end computer part taken care of by a rep at the same store yesterday, and did the rest myself.

I can provide a backup of system but already rooted / disabled dm verity before I took the backup so /boot you'd have to snag the stock kernel, let me know if you want the nandroid tho.

Dang bro, you pop up everywhere I go around here, lol. Remember me from the moto g helping getting data on cm? Your the one who posted the nasa gif when we got it right? Anyway, I would gladly take what you have rooted or not, and any other imgs you would be so kind to provide me with. I was about to buy another now that they're $20 cheaper than when I got my first. I knew that would happen. I wanted to get my wife one anyway. I was a dumb ass and ran a flash all script for sprint stock firmware and forgot to remove everything but the system sparse chunks. So now I really need full stock firmware. Thanks a lot for responding man!

Hey, don't you have a LG volt?

Hello guys, i have two questions:
a) after you unlock bootloader on this device, is it possible to flash the non boost (international e4) rom on it? if so, have you done it?
b) i used to have a moto e2 from boost mobile (xt1526) and did this with the unlocked international e2 rom (xt1527) and i was able to use my gsm networks with it as i dont live in the U.S and CDMA bands dont work in my country, would it be possible with this device too? Because GSM bands are embeded in snapdragon chipsets, so flashing a stock unlocked firmware should make it work, but i want to know if you have tried it

[INFO][PERRY] Pulled the OTA from BOOST/Sprint phone. Don't know if it could be used.

I picked up the Moto E4 recently and rooted it. The OTA has been sitting in limbo because I didn't wanna get screwed and get stuck in an non-root attainable update. As soon as I got root, pulled it, and here ya are. I have included a list to procure as well.

I hope it helps.

Could you possibly make a back up and upload it for me before you make any system modifications. I have boost but my original backup got corrupted somehow and I want to make sure what I'm running is the right firmware. I also want a backup of that original firmware. If you could also do me another favor and pull the oem.img and modem.img and upload them along with the recovery.img? I'm making stock ROMs and for some reason a rom made with what I thought was Sprint firmware works fine, but one made with what I thought was Boost firmware gives me a boot loop for some reason and I'm trying to figure out why? I'd really appreciate it. If you don't know how to pull the imgs I can instruct you, it's really simple. Thanks!

I just bought the Verizon varient. It updated today. I plugged into my PC and ran Kingroot. It asked to "try new root strategy", something it did not ask before. Root still fails though.

"This is the older update, right? Not a new one..."
Probably, it will bring NCQ26.69-33 to NCQ##.##-35 for Boost. (According to meta file in zip)
"I also want a backup of that original firmware"
Since I've already rooted, unrooted, lost cell service, lost system, and, just today, bringing it back to a usable state, I can vouch for the NCQ26.69-33 located here
Use the RSD XML-to-flash tool. Found it on Google somewhere.
My best advice is to use the "dm-verity-opt-encrypt.zip" located in root guide before any flash, especially if it entails a system related modification (ie magisk, scripts, etc). If ya get a non-flashable state, flash the boot.img again in twrp, reboot and redo the flash "dm-verity-opt-flash.zip"
Many thanks for kartik verma for posting the OEM device files link.

Using Motorola's company website to get the unlock key and using fastboot to flash, as stated in the rooting guide, is most thorough. Less 3rd party spam too
I have Boost but digging in the device files has shown a lot of 'verizon' being in various system files. Sprint, is Sprint, especially in prepaid flavors, imho.

I flashed the Sprint firmware and had data working on my XT1766 after it got it's carrier update, the Sprint firmware does not soft brick the phone as I flashed it and can confirm it doesn't soft brick it, so you are incorrect in saying that.

I'm not sure if I did something wrong but after trying this, my phone kept saying, "phone stopped working". I had backed up my phone so I restored it. Any ideas on what might have happened?

The steps are there. Just don't use the root part if you don't want root. Once you switch the files, flash the service file.xml with rsdlite.

While Turing on the phone " BAD KEY" msg pops up on
Black display for 4-5 seconds and then mobile shows Motorola logo...

That's normal if you unlock the bootloader. Flash the no verity opt encrypt, or magisk, and it will change from bad key to n/a. But there will always be a message if you unlock the bootloader.
I know you said you don't need root, so that bad key message is there to stay.

N/A will be there. But you can flash a new boot logo to kinda hide it. Instead of a black screen, any logo you want, maybe with a white strip at the top to hide it. I'll get you a link.

@madbat99
Everything you shared was perfect I made my own logo to hide bad key apn working ..
Now I want to have thebroot access in my phone XT1766..
TWRP IS ALREADY ISTALLED ON THE PHONE AS I AM FLASHING LOGOS..
WHAT SHOULD I INSTALLED TO GET ROOT ACCESS ..
SUPER USER ETC.. PLZ SHARE WITH ME..
and the main reason to have the root access is, I want to block or disable OTA update ..
Plz confirm, how will it be possible ..as I downgraded to get working APN But phone updated again now.
I want the phone to be stopped from being updated..
Plz help me out fixing this..
Thanks

Just don't accept the update. You can root by flashing magisk. You will still receive update notification. You'll need to disable the moto update app. I forget which one exactly. But your phone shouldn't be able to do ota updates once you are rooted with twrp installed. The update will fail.
here is the root thread.

Thank you. I wish I had known this. I had to flash the stock recovery, etc for the updates to work. A little bit of an unnecessary hastle.

Ota updates will likely always fail if you have twrp, or have modified the system in any way. The ota performs many checks (assert props) to see if the system is clean. If any asserts fail, the ota will fail. Even restoring the stock recovery doesn't guarantee the ota will work.

Last Resort Regarding Carrier Switching

I'd like to start off by apologizing if there's a thread that has answered this. I've spent nearly a week trying to find my answer because, I'm one of those that doesn't like duplicate post to begin with or those who don't google however, I can't find my definite answer and I just want to reassure before going and spending money.
Scenario: I recently have been given an AT&T Galaxy S9 and I'm mad in love with it (using an iPhone X at the moment lol) and I need it to work on Verizon. Of course my first step will be unlocking the device to be able to be used on different networks and I do by putting in the code that I received and it does unlock it. I proceed to put my sim card in it and I notice I can't seem to get service to work. I noticed giving my Note 8 Verizon to my friend who has AT&T, he could put his sim card in and it'll restart with all AT&T functions including the boot logo and all. My S9 AT&T rejects it still. I did try and tinker with the dial codes (*#*#4636#*#*) and setting my bands to LTE/CDMA. Doing this allowed me to receive 4G LTE on the device but, no cellular service. With that being said, I've read on threads that firmwares from certain manufacturers disable bands so I assume AT&T has those disabled that work for Verizon. My next step was trying to get a verizon firmware to work on it. I downloaded the ARG8 U firmware from verizon for it and it still boots AT&T firmware regardless. My last thought would be waiting for the updated V3 U1 Firmware for the S9 and maybe that'll fix it? I just need some opinions on this matter because, if I can't get this to work then I'm going to proceed on buying a new one unlocked.
Thank you guys in advanced and again, if there's already answers for this then I apologize. I've worked with android since the HTC Hero days and I still get stumped on some things haha.

Yes.. wait till XAA-U1 is available or an ATT firmware with userdata file inside which has all ATT related files.

When you say ATT firmware do you mean Verizon? I'm trying to convert from ATT to Verizon which I've tried a firmware with Verizon's userdata inside and all it did was double my bloatware lol. Had ATT and Verizon BS. As far as the XAA-U1, I understand then.

Yeah, I misread..
try VZW version
https://updato.com/firmware-archive-select-model?record=12EDD7F878D311E89F15FA163EE8F90B
Or VZW U1
https://updato.com/firmware-archive-select-model?record=E2DA06D078D411E89F15FA163EE8F90B
For proper functionality, make sure there's a "userdata" file when you unzip.
Also, use CSC file which wipes the phone, not home csc file which keeps data intact.
If things don't work.. keep sim inside and do a factory reset with sim. it'll ensure proper CSC selection.

See the issue is those links you posted are meant for the V2 bootloader. G960UOYN(2)ARF4 . I've actually tried the U1 and all from V2 but, it gives back that binary fail due to me being on the V3 bootloader. I'll try with the V3 bootloader files for verizon again and do the whole factor reset afterwards. Unfortunately there hasn't been a V3 U1 yet for the S9. Thank you for helping me figure this out, i'll post my results shortly.

Updating from earlier, I tried with the Verizon U3ARG8 file and all it did was add on the bloatware from verizon. I've tried factory resetting and all and it still doesn't want to swap over. Every time it boots, it begins with the AT&T boot logo and proceeds to not give me proper service. I can mess with the LTE bands and get data working, just not service itself.

In S8, there's a method using Combination rom (factory binary) to do a proper carrier switch. Take a look and try. Not sure if that would work, but that's an option.

Just tried it, once you get in the factory binary, you're supposed to type *#243203855# in the dialer and be able to switch it there however, it's not allowing me to do so. All it does is clear what I've typed.

S8 needs flashing canadian CSC before flashing factory binary. Did you try that too?

The Canadian csc is XAC right? Just trying to hunt for one. I don’t see any for the G960U. I see XAS (unknown) but, I don’t believe it’s the same thing.

You must look for G960W files for Canadian csc

Got it, however, since it's the Canada one, it only allows me to change the CSC to companies from Canada. It doesn't allow me to type the code in factory binary but, it does in stock rom with the XAC CSC flashed. I tried the adb shell where you use the echo function but, I get the common problem others do "/system/bin/sh: can't create /efs/imei/mps_code.dat: Permission denied".
Seems though we are getting closer and closer, never seen something so stubborn haha. Sucks there isn't a U3 XAA yet.

Flashing process
Factory binary,
Do reboot to bootloader via ADB,
Flash Canada "Home CSC" (not plain CSC)
Dial *#243203855# via IME button
Choose XAC, let it restart,
On adb shell, Type in
echo "VZW" > /efs/imei/mps_code.dat
(Make sure to include quotes on VZW)
If that's what you did, i think we are done here (Can't think of any other options)

Meant to reply back but, after flashing the hell out of the phone, it somehow went into XAA CSC and I factory reset it and afterwards it allowed me to connect to Verizon. Thank you so much!

Hi,
Im also trying to convert a VZM S9 to a Canadian CSC. Do the above steps work? because after i flash the factory bin, boot into it, when i try to flash the home_csc from the canadian fw, it always fails, no matter which odin i try. also that IME code, is it only supposed to work once the canadian home_csc as been flashed? because if i try that code in the IME section of the factory bin, i get nothing!
