[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
yes, I agree. Just one quick additional info:

If a T-Mobile user uses B12 on a compatible VoLTE phone, than the system will stay on LTE network (Voice over LTE) and this part is officially not supported. My quick question is:

Why Verizon and AT&T were able to go through on this process and why T-Mobile was not ? ...

I'm flashing the newest "M" system image on my decrypted 5X and I'll keep the old radio and modified bootloader.
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
All right,

I have flashed the new M build. It is basically the security patch for November. It is working with the F radio build and you will have B12 access, however if your device was rooted earlier, than YOU WILL lose your root access on the device. The root is still available on the I firmware with Chainfire's modified bootloader.
[Nexus 5X Q&A, Help & Troubleshooting] formula91:
You shouldn't lose root with the systemless root method

All you have to do is flash the stock boot.img, system upgrade, then flash the systemless root boot.img

Most reports are saying that the new system update works with the root boot.img meant for the old build, of course, your mileage may vary, thermonuclear war, etc etc. Worst thing that happens is that you have to downgrade to keep root or flash stock boot.img and be rootless. Either way....
[Nexus 5X Q&A, Help & Troubleshooting] just4747:
I flashed the radio per the instructions and I haven't once seen band 12 while checking LTE Discovery app in all sorts of buildings and areas (with Wifi off).

All I ever see is it showing LTE band 4 in the main Signals tab screen and same in the LTE Log. Also, not getting any better signal in my own brick apt. building, which has trouble getting much of anything when you are deeper inside the place away from windows.

Is there a way to check definitively:

1. What bands an area even has to begin with?

2. What bands my phone can currently get (ie. confirm that the radio flash did anything, even though everything seems right compared to what the thread shows).
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
It was a Project Fi specific post which uses T-Mobile's network. (and Sprint)

T Mobile bands are: 2 & 4 and the new low frequency Band 12.

Band 12 is not available everywhere, they do not have national wide license.

What is your location?
[Nexus 5X Q&A, Help & Troubleshooting] just4747:
Thanks. I am in CT in the Fairfield County/New Haven area.
[Nexus 5X Q&A, Help & Troubleshooting] formula91:
http://www.spectrumgateway.com/t-mobile-700a-spectrum

A quick look here says that your entire state should have 700 MHz coverage.

It's possible that the phone connects to Band 4 over 12. Seems to be the case.

Maybe go into a basement or elevator and see if that changes when you get the chance?
[Nexus 5X Q&A, Help & Troubleshooting] solara1973:
My area, central California, is practically covered according to their map. But I either get Band 4, or HSPA. I have yet to see Band 12 - Baseband version is M8994F-2.6.22.0.56, and currently on Google Fi.
[Nexus 5X Q&A, Help & Troubleshooting] jgummeson:
Question - How does one tell which band they're currently connected to? I have seen "LTE" in my signal indicator. I also have the option for disabling enhanced LTE in the mobile networks menu. I installed the system update that showed up when I first connected to WiFi. My baseband version is M8994F-2.6.28.0.65 and bootloader is still locked so I've done nothing to try and flash radio firmware that supports band 12 like everyone is talking about. Does the signal show something other than "LTE" when you're on band 12?
[Nexus 5X Q&A, Help & Troubleshooting] solara1973:
I use Signal Check Pro: https://play.google.com/store/apps/details?id=com.blueline.signalcheck&hl=en
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
It will show the same "LTE" on your device.

If you can see Enhanced LTE option, than you are probably not on T-Mobile's network and you will not get advantage of this modification.
[Nexus 5X Q&A, Help & Troubleshooting] jgummeson:
I'm on T-Mobile. Or at least I'm using a T-Mobile SIM card (not project fi).
[Nexus 5X Q&A, Help & Troubleshooting] baiju2012:
I changed the Sim in my 5X from Fi to T-Mobile, the Enhanced LTE option automatically appeared. I am sure that this option is available in T-Mobile.
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
yes it will appear, if your provider offers VoLTE on any of its frequency bands . You can disable the VoLTE, if you are not happy with your battery life for example..

Hi,

Is it possible to use this trick to get band 12 on international 5X (H791)?

It would be dream come true for me if the 5X can have band 12 and 8, 13, 28.

Thanks,
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
The international version has probably different hardware or at least a different antenna design. I do not think you will find an "universal" radio image. I might be wrong. Simply download several different radios and flash and test them.

Hi there, I found this thread http://xdaforums.com/nexus-5x/development/tool-5x-multi-tool-v0-1-t3216388 so I use this tool to unlock my phone, right? Next, flash the radio through ADB... I googled, is this Android Debug? Sorry I am pretty new with this, but can you point me in the right direction a thread to read or something about replacing the radio with the img from this thread?

And one other question - if I do this, and then t-mobile sends out an update later that enables band 12, will the updates work fine with no problems?

Thank you!
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
yes, you can use that tool, however you can unlock it with an easy fastboot command as well.

Simply enable the OEM Unlock option in the Setting menu. (Important)

Than turn your device off and boot it into download / fastboot mode. Connect your USB cable.

Open the Command prompt on your computer in Administrator mode

use the "fastboot oem unlock" command.

REMINDER: OEM unlocking always wipe all of your current data (pictures/music) etc , make a backup!

Once you have finished the phone will reboot and you can install the new radio img.
[Nexus 5X Q&A, Help & Troubleshooting] banana_time:
Ok, I did that and flashed the new radio image. I then, I think stupidly, re-locked the bootloader and reset my phone. Anyway, it is connected to band 4 now. If I have band 4 and 12 coverage somewhere, will it always use band 4? Is there a way to set the priority of bands to use if multiple are available?

Thank you for your help!
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
if you relocked it back, than you will get the next official update and that will overwrite the radio what you recently flashed.

If you go to Settings -> About phone than what kind of Baseband version can you see? I'm just curious..

thanks
[Nexus 5X Q&A, Help & Troubleshooting] banana_time:
Oh dang! I did notice after it booted that little robot displayed for a few seconds, the updating one, but it didn't say anything about applying an update. Could it have already been downloaded on my phone so it just applied it immediately when I rebooted?

The baseband is M8994F-2.6.22.0.56

Mean anything? I am going to re-flash the radio right now and keep it unlocked.

---------- Post added at 01:40 AM ---------- Previous post was at 01:24 AM ----------

Ok, I reflashed the radio. Still no band 12 but maybe it is just my area. I will keep an eye on it tomorrow when I am outside and see if I get band 12.

Thanks for helping!
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
you are most welcome!

You did everything correctly and you have the B12 compatible radio installed. You will get B12 once the higher frequency bands are weaker for sure. (mostly on highways and rural areas)

Once you will get an update notification do not immediately install it. Research a bit, that will most likely a security update for December. I hope early next year this band will be officially supported.
[Nexus 5X Q&A, Help & Troubleshooting] banana_time:
Well it looks like I am a supreme idiot. I am in San Diego - no T-Mobile band 12 according to a map I should have checked before I tried this. I am not happy about that, but at least I learned a little about fastboot and flashing.
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
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...

Hopefully Project Fi also will update their next OTA with this radio. (we should get VoLTE access as well on T-Mobile, hey Google are you listening????? ;) )
[Nexus 5X Q&A, Help & Troubleshooting] baiju2012:
Thanks for verifying it. I have been waiting for it for a long time. One of the main reasons for buying 5X.:D

Update: Side loaded the update. Band 12 is working now. :D
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
I completely flashed the new update (boot, bootloader, vendor, cache and system images).

You can download the latest SuperSu 2.61 ZIP and install it via TWRP. You do not need the modified Boot image file. SuperSu will patch it.

Very important! Once you've installed the SuperSu ZIP, than DO NOT allow for TWRP to root the system one more time at restart . Say "No" , because it will break the kernel and the system will not boot up. Simply wipe the cache and Dalvik and restart the phone and you will have the latest rooted B12 compatible firmware installed.
[Nexus 5X Q&A, Help & Troubleshooting] baiju2012:
Thanks. Good to know. I am unrooted and on stock. Will like to remain like that. Don't want to deal with different setups. I am happy that I have latest Android OS with band 12 from T-Mobile in $30 plan. Thanks again for all the help. :)
[Nexus 5X Q&A, Help & Troubleshooting] banana_time:
Buddies I have a question. If I leave my bootloader unlocked will my phone still get updates? If I re-lock the bootloader will it get updates? Is there anything special I need to do if I just want my phone back to stock so it can get updates like normal again, since the band 12 issue is solved (and I don't get band 12 here anyway)

Thanks everyone!!
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
you will get notifications of an available update and you can install the OTA update if the bootloader is unlocked. (At least it was the case with my old Motorola Nexus 6)

If you are rooted and the system is still the factory image , than you will see the update, however the update will fail.

I can not see any reasons to relock the bootloader other than a warranty repair or sale.

You only side loaded the radio file, the next OTA most likely will install without any issues. One more important thing: you will lose all personal files and settings during the re-lock process. Backup your system ;)
[Nexus 5X Q&A, Help & Troubleshooting] banana_time:
Hello again and thanks for responding. well the scenario has been tested - I tried to install an update today and it said it was installing, then a error happened. The android robot was laying down with a red triangle in its belly and it said error. I held the power button for like 10 seconds and it rebooted and seemed fine. This happened twice, so I don't think it's gonna work. Should I try locking the bootloader?

Thanks again
[Nexus 5X Q&A, Help & Troubleshooting] acsontos:
If you flashed or side loaded the radio file only, than you should flash back the original one and give it a try again.. The update might check the baseband version. If it will not work, than you need to relock the bootloader to be able to install the OTA update. (backup!!)

I also use the latest rooted stock ROM. I mainly need the root for Ad blocking and for Titanium backup. I always download the latest full firmware and install the files manually.
[Nexus 5X Q&A, Help & Troubleshooting] banana_time:
Do you know where I can find the original radio file? All I can seem to find is the whole factory image, but I am not sure where to look or what search terms to use. I tried factory radio file, but no luck.

The initsh_replacer.zip already has a modified boot LED but note that I made it at around 3 AM and isn't so great. But if you'd like to test it out, flash that.

In case you don't like it, extract the init_sh_original.zip , you'll find an init.sh in there.

Have a look at it :)

Most probably, he must've used a code/script to automatically generate symmetric gradual increase and decrease of the brightness of those colors. (Even I've done the same for the init.sh file in the replacer zip. Wrote 20 lines or so in C to get around 70 lines =D ) No way he would have sat down and written 6645 Lines :p

Hello everyone. If someone could help me that would be great. I have a Galaxy S4 GTI9505. If anyone can supply me with a 4.2.2 debrick image, it would really be appreciated. I do have a 4.4.2 128 MB image but it is not working. I also have a lot of debrick images if someone can help me. It is a Quad-core 1.9 GHz Krait 300 CPU, Adreno 320 GPU; Qualcomm Snapdragon 600 chipset so it shouldn’t need a test point to force into download mode. I’m assuming the aboot is different on the lollipop rom and that is why I can’t get it to download mode. Can someone please take time out to help me?

To get the image you have to have a rooted Galaxy S4 on 4.2.2, and have to install busybox, and a simple syntax program like terminal emulator which you would have to install. You also would have to install root explorer. These are all android apps with the extension .apk. Once those 3 programs are installed you would have to press terminal emulator and enter this code:

Su (press enter) to get super use access, then on the next command type just like this

busybox dd if=/dev/block/mmcblk0 of=/sdcard/debrick.img bs=1M count=128

The image which will be put on the “sdcard” of the phone. Not the external sdcard but the internal sd card.

Then use root explorer to navigate to the root of the sdcard and copy it to let’s say your download folder.

Then plug in the phone and copy it onto your computer to copy on your desktop. Once you have the image then if you can send it to gavin.lin8@gmail.com it would be appreciated.

Please someone do not ignore this and help me. You would be actually helping a lot of people that need this image. Thank you.
