[MODEM][PORT]Stock Android 6.0.1 Baseband Radio for xt1526 Moto E LTE - E 2015 Original Android Development

XT1526 MOTO E LTE
STOCK 6.0.1 BASEBAND RADIO
VERSION: M8916_2020632.44.03.21.54.01R
PORTED FROM XT1548 MOTO G (3rd Gen)​
SPECIFICATIONS:
This is a Stock Android 6.0.1 Baseband Radio (/modem & /fsg) for the Moto E LTE, xt1526 model only. It has been ported from the xt1548 Moto G (3rd Gen), modded for full compatibility with the xt1526, and optimized for roaming on the Verizon network. This Baseband was pulled from Stock Android 6.0.1, Build No. MCIS24.107-82-18, System Version 24.221.18.en.US.
This Baseband installer is for the Sprint, Boost Mobile & Virgin Mobile variants of the xt1526. It HAS NOT been tested on the US Cellular xt1526 variant. If using the Boost Mobile xt1526 variant, XDA Member @anthonykb has reported that the device must first be updated to a 6.0 Stock bootloader.img and partition index (gpt.bin) before this Baseband will function. Anybody with the Boost Mobile xt1526 can head over to @Buzbee2's thread on ported stock 6.0 for the xt1526. You will simply need to flash the 6.0_Stock_Partition_Updater zip available in Buzbee's thread. https://forum.xda-developers.com/mo...stock-xt1521-gsm-xt1526-cdma-t3342789/page19. For members who use @Buzbee2's thread and/or files, be sure and hit the thanks button on his thread.
This Baseband should work on all CM/LOS, AOSP, Stock, & Stock Based ROMS, on any Android Version from 5.0.2 Lollipop to 7.1.2 Nougat. You should notice a marked improvement in connectivity, signal strength, download/upload speeds, and domestic roaming. This Baseband has been optimized to force handover of data connectivity to the Verizon network in situations where (1) your signal on the Sprint towers has fallen below a 110dB signal; and (2) when your xt1526 cellular radio is unable to locate a viable Sprint signal. NOTE: The optimized roaming mod has only been tested on stock and stock based ROMs. This feature may or may not work on custom ROMs such as CyanogenMod or LineageOS.
NOTE: This Baseband performs best on Stock Android 5.0.2 or 5.1 factory firmware.
DISCLAIMER:
Flashing the partitions of your device or altering its stock factory configuration poses an inherent risk of bricking or rendering your device inoperable. By proceeding any further, you absolve me of any liability in the event your device is damaged in any way from installing this radio firmware.
Follow the instructions closely and things should go smoothly.
REQUIREMENTS:
For purposes of this guide, you must have an unlocked bootloader and TWRP custom recovery installed on your xt1526. If you do not have both of these requirements, search the XDA threads for tutorials on how to do so. While it is certainly possible -- and feasible -- to flash this installer using an on-device flashing application, like Flashfire, this thread is geared towards installation via TWRP custom recovery. (Preferably @squid2's 3.1.1-r1 rebased build) Be sure and hit the thanks button on @squid2's TWRP thread if you use his recoveries.
INSTRUCTIONS:
1. Download the Baseband Updater zip from the below link and save it either to internal storage or your external micro SD card;
2. Boot your xt1526 into TWRP recovery;
3. Select INSTALL, navigate to the storage location of the zip you downloaded in Step 1, select the file, and swipe to commence with installation.
4. When installation is complete, reboot system. Done. Your xt1526 Baseband Radio is now updated to M8916_2020632.44.03.21.54.01R.

I just tested this on Boost xt1526 with ViperOS and it didn't work. I'll try flashing and doing a clean rom install and see if it makes a difference.

Yes do a clean install always. I need to incorporate that into the instructions. Also, if you do a "dirty" install, you can always clear nv data by by entering fastboot and using: fastboot erase modemst1 and fastboot erase modemst2. This baseband seems to perform best on stock based ROMs.

I did do erase modemst1/2, but it didn't make a difference. I was going to mention you can add erase modemst1 erase modemst2 to the update script without the fastboot part and it will work. I'll try a clean flash and report back.

I did have the format command in updater-script but removed it, because many people do not want nv data erased upon installation of the baseband. I may have to revise the thread to clarify Virgin Mobile only. It doesn't seem to be working on Boost. Thank you for your testing. I really appreciate it.
By the way did you try:
fastboot oem confg fsg-id boost
fastboot oem config carrier boost

---

I just revised the thread to specify Virgin & Sprint only for now, until further testing can be done on Boost. In theory it should work on Boost, since the Virgin & Boost xt1526 variants both used the same stock firmware builds.

Interesting, so the Boost variant must first have the bootloader and partition index updated to stock6.0? Good find. Glad you got it working on your Boost Mobile variant. @anthonykb, what I'll probably do, or you can do it either one, is go ahead and incorporate gpt.bin and bootloader.img from stock 6.0 into my updater-script for Boost users. For Virgin & Sprint users, I'll leave everything like it is.

I was already updated to the 6.0 bootloader and even with a clean install it still didn't work for me. Won't read sim card at all.

Hmmmm. Did you fastboot configure your carrier and fsg partitions?
fastboot oem config fsg-id boost
fastboot oem config carrier boost

Try this, and I think we can get things working. Install a pure stock 5.1 firmware build. I'll get you an Aroma installer that will configure your configs for Boost Mobile. I want to try pure stock because we need to do a PRL & Data Profile update. Use any 5.1 build except s.12. And, of course, disregard flashing gpt.bin or bootloader.img from the firmware package of 5.1.Let me know if you install 5.1 stock. I'll get some of the files together we will need. Also, should you need any firmware builds for your xt1526 let me known. I have all firmware packages that were ever made for the device. I've got fastboot flashable packages and TWRP flashable zip versions.

Here is the Aroma installer. Simply flash this using TWRP recovery. Select "Boost" when the installer prompts you to choose a carrier.

You could try the Aroma installer now, before going through the 5.1 firmware package flashing. There's a pretty good chance that the Aroma installer alone will configure the baseband to work with Boost on your device.

On the Boost Mobile xt1526 variant, here is what I just done and it worked perfect on mine. I "dirty flashed" the baseband installer, basically installing the radio firmware and leaving nv data intact, then rebooted system. On the stock dialer, I opened the SCRTN Menu (Network & Carrier Config Reset) by dialing ##72786# and choosing "YES" when prompted. Upon reboot, I again booted into TWRP and installed the MVNO_Slayer Aroma zip and selected "Boost" from the carrier menu. Then I rebooted system. RIL is fully functional, as is 4G/LTE data connectivity. Updating my partition index and bootloader to stock 6.0 was not necessary. (My bootloader.img and gpt.bin are the original stock 5.0.2 versions that shipped on the Moto E LTE xt1526 during initial release of the device).

---

@anthonykb, I'm going to compile a separate zip installer for the Boost variant. It can be done one of two ways, both of which we have confirmed to work: (1) I can either include stock 6.0 bootloader.img & gpt.bin in the zip/updater-script, or (2) I can reincorporate a format command for modemst1 & modemst2, and include the apns-config.xml/eri.xml for Boost from the mvno_slayer Aroma installer. What are your thoughts?

---

Just wondering, are the IMG files essentially the same as fsg.mbn and NON-HLOS.bin? Regards

img, mbn, bin, etc, are all image type formats which can be flashed from fastboot. For the purposes for which I am using them, yes they are exactly the same. To clarify, NON-HLOS.bin and modem.img are the same, and fsg.mbn is the same as fsg.img.

---

@tzheng0311 have you given this a try on your DDR devices yet? Works great on forced roaming on DDR, on stock ROMs anyway. I've not had a chance to test the data handover on custom ROM roaming yet.

---

I'm going to try it later on today, thanks for the heads up. I'll let you know, I have like 3 on stock ROM and the rest on CM13
Edit: Woop, turns out i'm on S.12 and this baseband really doesn't like it lol, gonna update first

Did you get this to work running stock or a custom rom? I tried again running HalogenOS and still didn't work. I'll restore stock and try it, then if it works I'll try flashing some custom rom. When I can have my phone down for a bit.
