This tutorial can be used to flash a carrier (not retail) phone? I have a XT1225 from Movistar Chile. I have unlocked the bootloader and sim unlocked, all thanks to Motorola Support.

My current firmware is

Base band: MDM9625_104335.118.02.54R

System: 21.11.9.quark_tefla.tefla.en.01 amxcl

Sorry if this has been asked before. I have been watching the forum for a couple of days and couldn't find anything related to carrier phones.

Thanks.

Thanks to you, now both my Moto Maxx phones now are "Moto Turbo" with India Lollipop 5.0.2. The daily one I use has Gravity Box (Lollipop) installed for now.

I also have your black boot logo on both. :)

Thanks! in weekend I will give it a try.

EDIT: One more question. If I want to install Mexican Lollipop. Do I have to install First "Mexico Retail Stock Kitkat" and then "Mexico Retail OTA Kitkat to Lollipop Official" ? Or the Lollipop is a full image (the name suggest to be an update, not full firmware).

Thanks.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Jaocagomez:
stock kitkat and then Lollipop OTA
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] arigatox:
I have flashed the indian firmware. All the process went well. Lollipop starts, but the SIM is not detected, and the wifi can not be activated? Did I miss something?? :crying:

EDIT: it seems to not recognize the band base. In "about" it says: "Base Band: Unknown"

EDIT2: Tried installing RETBR_XT1225_4.4.4_KXG21.50-9_cid12_subsidy-DEFAULT_CFC.xml but phone does not start. Mmmmmm

EDIT3: I search for a firmware with a similar base band of my previous firm. I found NIIBR_XT1225_4.4.4_KXG21.50-9_cid12_subsidy-DEFAULT_CFC. Flashed, phone booted, sim and wifi detected... That's a reliefffff. I am going to sleep now and tomorrow maybe give it an other chance.

Hey [MENTION=3250376]ChazzMatt[/MENTION]

I went from PR to BR and using LA now.

Any difference worth to change to India LLP versus BR or LA?
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
Someone said the India Lollipop 5.0.2 is smoother. They were going by the various Latin America soak tests. I have nothing else to compare it to myself. I didn't install any of the soak tests.

India Moto Turbo XT1225 (same hardware, same FCC ID as the Moto Maxx XT1225) came straight from the factory with 5.0.2.

The only other advantage for me is technical one -- most current specs for the XT1225 are on the official Motorola India site. Not only that is has Lollipop 5.0.2, but both the XT1225 Moto Maxx and XT1225 Moto India are IDENTICAL in hardware and other specs (same FCC ID and everything). Yet for some reason, for the Moto Maxx XT12225 Motorola does not list all the enabled bands which the FCC found and which I found. Yet, they list them on the Moto Turbo. :confused: Go figure.

This would probably be more important for people living in U.S. and Canada., for owners who would use those bands. Rather than believe me, they can believe Motorola! :good:

I no longer have to "prove" with QPST/QXDM, modem scans, LTE nav calculator, etc which HSPA and LTE bands are enabled on my Moto Maxx XT1225. :rolleyes: On the Motorola India Moto Turbo page, Motorola finally lists all the additional bands for the Moto Turbo (which were really also enabled with the Moto Maxx XT1225) -- but for some reason they didn't want to admit to earlier. ALL the AT&T LTE bands (2, 4, 5, 17), ALL the T-mobile HSPA bands. Since my phone now says "Moto Turbo" instead of Moto Maxx, when I finally sell my spare phone, the buyer can see for themselves on the specs page.

fastboot flash system system.img_sparsechunk.7

fastboot erase cache

fastboot erase userdata

fastboot oem fb_mode_clear

fastboot reboot

My question is if I will flash now the TWRP of course I will loose the next OTA... but when the OTA (5.1) will be sent, can I reflash the "original" revcovery.img from the Indian ROM (QUARK_RETEU_INDIA_5.0.2_LXG22.33-12.11_cid7_subsidy-DEFAULT_CFC.xml.zip) in order to be able to update it?

Hello

I bought my moto maxx xt1225 with the TWR, and the 5.02 lollipop

version LXG22.33-12.7, but im having several problems and i want to go to the stock kit kat mexican version

and then update to the Mexican lollipop

is this possible, or you guys have any other recomendation for me?

I would skip going back to kitkat and just flash the full retail mexican lollipop. It's usually cleaner to just flash the full retail rather then go back and then take an update.

hello...im in cm 12,1...i flashed through adb the brazil lollipop 5.0.2 which had the gpt.bin file. I want to downgrade to kitkat 4.4 now..from cm 12.1

whats the best way to achieved this ...i also have the back on twrp of the stock kitkat 4.4. do i restore that through twrp and then flash stock recovery

or do adb flash the 4.4. kitkat from this thread...also once i downgrade to kitkat 4.4 will it be able to take the ota for lollipop in the future since i already flash the gbt.bin file from lollipop mentioned above...thanks
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
If you downgrade to Kitkat 4.4.4 do NOT re-flash the gpt.bin file (which has been changed to Lolllipop). You flash everything except that -- via ADB.

If you want "Lollipop" in the future, do you mean like 5.1? Because you already flashed Lollipop 5.0.2 earlier, so you can re-flash that again very easily, then not have to worry about OTA files.

No need to take the OTA files. You can reflash any upgraded images via ADB that are posted here. Besides, you can't take OTA files safely anyway if any system file has been changed (like custom TWRP recovery). For me, having the custom recovery TWRP outweighs any ability to upgrade via OTA.

Basically if you want to downgrade to Kitkat 4.4.4, yes you can do that, and have all the functionality and attributes of Kitkat. Just don't re-flash the gpt.bin to a downgrade.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Jesushasadroid:
thanks so much for the info...yeah just want to downgrade to kitkat 4.4 for someone who wants the phone and wants kitkat for whatever reason...and if they get ota just want to make sure they can upgrade in future with ota...thanks

I want to convert a xt1254(locked bootloader) into xt1250 or xt1255.....can I do this with this tool??do I want to unlock the bootloader first??
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
NO, you cannot do that -- at least the XT1225 over XT1254 part.

You can't flash an XT1225 radio over an XT1250/XT1254, and vice versa. Different FCC ID, different bands.

Even [MENTION=7109882]iiWoodstocK[/MENTION] 6.0.1 Brazilian Marshmallow stock ROM -- which can be used on an XT1254 -- uses the radio already on the XT1254 and uses [MENTION=5747496]bhb27[/MENTION] custom kernel to make it all work. He included CDMA build.prop lines so the XT1254/XT1250 radios would work on that ROM (but would be Lolliopop radio at this point in time).

[ROM][6.0.1][Stock][Odexed]MPG24.107-70.2 Brazilian 6.0.1 for XT1254[TWRP Flashable]

http://xdaforums.com/droid-turbo/development/rom-mpg24-107-70-2-brazilian-6-0-1-t3426234

IF you unlock your bootloader you can flash TWRP and install that

slightly modified Brazilian Motorola Marshmallow XT1225 ROM

which has a custom kernel, but it will still use your current (XT1254) radio. Unlocking the bootloader is always a good thing, as it allows you to install custom ROMs, install TWRP and all other goodies. So, unlock your bootloader no matter if you can't do this particular thing you are asking about.

You CAN flash XT1250 radio over the XT1254 and back and forth, as they have the same FCC ID and are just the same device with two different names. But what would that accomplish for you?

Why would you want to convert your XT1254 (Droid Turbo) into an XT1250 (U.S. Moto Maxx)?

It's the same device, same FCC ID, same radio bands. Some people have done it to get rid of Verizon bloatware, but you can do that just as easily by rooting and manually removing the bloatware.

And why would you want to convert your XT1254 (Droid Turbo) into an XT1225 ("international" Moto Maxx/Moto Turbo)? What do you hope to accomplish? If you goal is to get the XT1225 radio bands, then you should have bought an XT1225... I'm not trying to be harsh, I'm trying to understand your goal.

______

P.S. Everyone else: this thread was written back when we were all in one forum, so ignore the "not for Droid Turbo" in the op. It was written before Sunshine unlocked the bootloader of the XT1254.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ixionk@gmail.com:
Great Job!!

I have a question, actually I have custom rom Cyanoged CM 13 with bootloader unlock, in my Moto Maxx XT1225 and wanted flash to Marshmallow official Motorola... I can use this tutorial to flash my smartphone and don't get any problems?

Btw I'm from Mexico too..

Saludos chingao!!! jajaja :cowboy:
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
Yes. Just make sure in step #5 you flash ALL the sparse chunks you have and not just what's shown in the example. Different images have different number of sparse chunks, sometimes MORE than shown in the example.

Which Marshmallow XT1225 image will you be using?

Alternatively you can flash [MENTION=7109882]iiWoodstocK[/MENTION]'s Motorola Marshmallow image. It's stock except for a modified kernel, and works on any Quark including your XT1225. (I own three of the XT1225; one bought from Mexico through the help of the op [MENTION=2920544]Jaocagomez[/MENTION]. My wife is using that one.) Flashing that might be easier for you. It's just like flashing a custom ROM in TWRP:

________

If you have TWRP installed, you can use this TWRP-flashable version.

http://xdaforums.com/droid-turbo/development/rom-mpg24-107-70-2-brazilian-6-0-1-t3426234

If you flash it you have to be rooted and have TWRP installed. Verizon's VoLTE will not work on the Droid Turbo, but everything else does. It's pure factory Marshmallow for ANY Quark -- XT1254, XT1250, XT1225. It will use whatever radio you already have installed.

Data 3G/4G not working!!

Tks so much!! I flash using TWRP and the ROM what you suggest me, and works but the "Data network" is not working, only phone line and wireless works but 3G and LTE (4G) is not working.

My phone is unlocked by brand factory never branded by a carrier company. I use TELCEL MX as a carrier.

Yo know what can I do to fix this problem??

Thanks again for you help!!

Grettings!!
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
First, try flashing [MENTION=5747496]bhb27[/MENTION]'s Clean Modem Status zip in TWRP recovery. It clears out stuff that can confuse your modem.

Clean_modem_status.zip

https://www.androidfilehost.com/?fid=24531035584725320

Second, if that doesn't work, then re-flash radio/modem for your XT1225. These are TWRP-flashable files, thanks to [MENTION=5747496]bhb27[/MENTION].

Marshmallow and Lollipop XT1225 radios

[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ixionk@gmail.com:
Tks for you help!! But maybe this not working on Moto Maxx XT1225 Mexican Device... I did flash the "clean modem status" and get worse.. erase IMEI CID caused not get signal by carrier. :(

So what I did was restore my backup (CM13) but not restored the modem configuration. :crying:

Finally flash using RSD Lite the rom stock XT1225_QUARK_RETLA_6.0.1_MPG24.107-70.2_cid12_subsidy-DEFAULT_CFC.xml.zip with hope that fix the problem... and woala WORKS!!! Finally have what I wanted in first place.. get marshmallow original firmware. :D

So I think used the Brazilian based ROM on other region might be no functional for the data network. (at least in Mexico).

Tks again for you help and sorry for my english (I still learning.. :p )

android system occupies 40BB of 64GB

Hi everybody.

I have an unlocked droid turbo 2. I updated the software through update software but update failed and the phone was on fastbood and didnt start. I tried to install official Roms using RSD Lite but it failed. So I tried to install official ROMs through guidelines in this tread. It worked and the phone worked but 40GB of 64Gb is occupied by android system. How can I free my space and partition it?
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Spott07:
You might get better answers if you ask this in the Turbo 2 sub-forum, instead of the Turbo sub-forum.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] melina_rosy:
I used this tutorial; so I posted my problem here but I ask it again in droid turbo 2 too
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
And here's why you used this tutorial, because the IDENTICAL tutorial by the same person [MENTION=2920544]Jaocagomez[/MENTION] specifically says it's NOT for the Droid Turbo 2.

https://xdaforums.com/droid-turbo-2/general/x-force-how-to-manually-flash-official-t3282077

Why? Because the Droid Turbo 2 bootloader cannot be unlocked.

[MENTION=2920544]Jaocagomez[/MENTION] had the Moto Maxx phone first and this forum used to be for ALL Quarks before it was split in September 2015. Even though posted in this Droid Turbo forum, he says:

And the reason he said that was because at the time the Droid Turbo bootloader was NOT unlocked. So, in both guides, he's saying do not use it on a phone with a locked bootloader. So, you ignored the Droid Turbo 2 guide and found this one, even though it's not for your phone and you have a locked bootloader?
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] melina_rosy:
I dont know whether my bootloader is locked or not. How can I be sure?
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Spott07:
Because you have a Turbo 2, and your bootloader cannot be unlocked, as of this time.

You cannot use guides for the Turbo because they do not work on the Turbo 2. The two phones are completely different devices. This is why there is a separate sub-forum for the Turbo 2, as I informed you initially.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] melina_rosy:
so I cant take back 40gb of ram? it definitely belongs to android system until I can unlock bootloader? there is no solution for this problem?

How about wipe cache partition? does it help? I'm afraid if I try wipe cache partition, I will lose everything.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] Spott07:
I don't know if you can get back your 40GB of RAM. This is the wrong place to ask that question, because we discuss a different phone here and don't know about your phone.

GO ASK IN THE DROID TURBO 2 SUB-FORUM, WHERE THEY KNOW ABOUT YOUR PHONE.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] melina_rosy:
Thanks. I posted my problem in droid turbo 2 sub-forum as soon as I get the information that I am on the wrong thread.

Hopefully, someone will know something about it.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] ChazzMatt:
Droid Turbo 2 bootloaders are locked, thanks to Verizon. They never got Sunshine to unlock them like the Droid Turbo XT1254 got. Over in the Droid Turbo 2/Moto X Force forum, only the "international" Kinzie variant Moto X Force has free unlock code via Motorola.

You CAN flash original firmware meant for the Droid Turbo 2 via RSD Lite, even with a locked bootloader. I did not mean to imply you could not do that. However, you have to do everything right, as it's much harder to recover from a mistake with a locked bootloader. This guide you found in this Droid Turbo forum was actually written for the Moto Maxx/Moto Turbo. I used it to flash the India Moto Turbo XT1225 Lollipop 5.0.2 firmware over my Moto Maxx XT1225 as Moto Maxx at the time still had 4.4.4 Kitkat.

If you flashed the official Verizon firmware using RSD Lite, I do not know why 40GB is missing. The official Droid Turbo 2 firmware is here:

Official Stock Firmware For all Kinzie Devices (Droid Turbo 2, Moto X Force)

https://xdaforums.com/droid-turbo-2/general/kinzie-stock-firmware-moto-x-force-t3279354

and you specifically want firmware for :

Verizon Droid Turbo 2 XT1585

also in that thread it says:

I don't know if that is still true, but consider that.

Also, in that thread, all the most current that is listed is Marshmallow, but you probably want Nougat, right?

Verizon Stock Marshmallow 6.0.0 /// KINZIE_VERIZON_6.0_MCK24.78-13.11_cid2_subsidy-1FF.xml

https://mega.nz/#!ddcDSDDK!_miN5ps3o...bb4p6-YE13JQco

I don't see Nougat. I think [MENTION=2920544]Jaocagomez[/MENTION] moved onto another phone and is no longer updating that thread?

To use RSD LITE you need the full firmware, not the OTA update.

Do you know exactly what you installed, and where did you obtain it? You said you used "official ROM", but in that forum I don't see Nougat for Droid Turbo 2...

See, these are all questions they can probably help you answer over there.
[Verizon Motorola Droid Turbo Q&A, Help & Troublesh] melina_rosy:
Hi

I used RSD Lite to flash firmware but it failed at the second step, so I used this guide to flash firmware.

the firmware I used was :Verizon Stock Marshmallow 6.0.0 /// KINZIE_VERIZON_6.0_MCK24.78-13.11_cid2_subsidy-1FF.xml

the exact firmware you quoted on the above.

I also used the RSD Lite 6.2.4 as uploaded on the thread you mentioned in the above. I dont know why it failed at the second step.

I really want to free the space occupied by android system because I specifically purchased 64GB version for its vast space but now I cant use it
