Enable DualSim

I have a problem, I'm from Mexico, I hope they can support me, since I've been looking for a solution in front of the PC for weeks, (I do not speak English, so I'll rely on the Google translator)

Buy the Moto Z Play, very good phone. My phone came with Android 6.0.1, update with normal OTA to Andorid 7.0 right here, perform the process to get the Dualsim, at first all perfect, worked, with any operator, I had no problem.

Just when the update came 7.1.1 the big problem started, install by OTA, somehow worked, but soon the Sim 2 stopped working, in addition to the reboot, whenever I turned it on Bootloader mode selected start and everything all right.

When trying to solve these problems with ADB Tools use these commands:

fastboot oem fb_mode_clear (To fix the automatic start)

Then, to solve the signal error in the Sim 2, use the following commands with ADB Tools:

fastboot flash modem NON-HLOS.bin

fastboot erase modemst1

fastboot erase modemst2

fastboot erase cache

And restart the phone with

fastboot reboot

NO SOLUTION !!!

The boot works, but the DualSim does not work on Andorid 7.1.1 with the Septiempre security patch, in addition to the command "fastboot erase modemst1" the IMEI has been deleted (I did a backup beforehand, I was lucky)

THIS IS A GREAT DATA FOR NOT TO TRY IF YOU DO NOT WANT TO LOSE THE DUALSIM !!!

At this point, the best feature of my phone had been lost, so I decided to start over.

1) Install ROM Stock, with ADB Tools (platform-tools)

The Rom is this:

"XT1635-02_ADDISON_IUSMX_MPNS24.104-44-7_cid50_subsidy-IUSMXLA_regulatory-DEFAULT_CFC.xml"

Commands:

fastboot flash partition gpt.bin

fastboot getvar max-sparse-size

fastboot oem fb_mode_set

fastboot flash dsp adspso.bin

fastboot flash bootloader bootloader.img

fastboot flash logo logobin

fastboot flash boot boot.img

fastboot flash logo logobin

fastboot flash boot boot.img

fastboot flash recovery recovery.img

fastboot flash dsp adspso.bin

fastboot flash oem oem.img

fastboot erase carrier

fastboot flash system system.img_sparsechunk.0

fastboot flash system system.img_sparsechunk.1

fastboot flash system system.img_sparsechunk.2

fastboot flash system system.img_sparsechunk.3

fastboot flash system system.img_sparsechunk.4

fastboot flash system system.img_sparsechunk.5

fastboot flash system system.img_sparsechunk.6

fastboot flash system system.img_sparsechunk.7

fastboot flash system system.img_sparsechunk.8

fastboot flash system system.img_sparsechunk.9

fastboot flash system system.img_sparsechunk.10

fastboot flash modem NON-HLOS.bin

fastboot erase modemst1

fastboot erase modemst2

fastboot flash fsg fsg.mbn

fastboot erase cache

fastboot erase userdata

fastboot erase DDR

fastboot oem fb_mode_clear

2) Install Chinese TWRP and reinstall EFS and FSG Backup (IMEI)

3) I did Wipe, and I already had IMEI with Signal on SIM1

4) Update by OTA to 7.0 HERE THE APOCALYPSE.

Just in this step, when updating officially, just before finishing the phone turned off and did not turn on again, it did FULL BRICK, so I had to investigate how to boot again.

So I got Blankflash, Android SDK Tools, Update Java, Update COM Drivers, ADB Tools (platform-tools) and the "bootloader.img" files "recovery.img" and "gpt.bin" from MotoG5Plus addison2Potter, somehow it worked.

The phone already turned on at least in "Bootloader" mode so I started again, but no longer install for OTA, because when upgrading from Android 6 to 7 I ALWAYS COME TO FULL BRICK.

To upgrade to Andoid 7.0 use an old Backup that I did before upgrading to 7.1.1.

I HAVE LOST EVERYTHING, I HAVE ALREADY THE PLAN BACK SO THAT BE SITTED IN FRONT OF THE PC.

At this point, I perform all steps of the DualSim, but so far I can not get them to work again as before.

Sim2 still has no signal.

I have tried using ADB Tools with the Commands:

fastboot flash modem NON-HLOS.bin

fastboot erase modemst1 (I no longer use it, ALWAYS erases the IMEI)

fastboot erase modemst2

fastboot erase cache

fastboot reboot

I hope that my case also serves as support for others, I have tried to be very clear, even boring XD

But I really need your help to have DualSim again, I hope they help me.
