[Moto G 2015 Q&A, Help & Troubleshooting] Yousvel:
You can go back and forth to lollipop from Marshmallow as long as you don't downgrade the bootloader. Modem is not a problem. You can downgrade it.

I personally downgraded to lollipop yesterday using fastboot. And the only thing I didn't downgrade is the bootloader. Today I received the MM ota again and installed it. So far, zero issue.
[Moto G 2015 Q&A, Help & Troubleshooting] JulesSDK:
My phone got bricked after trying to downgrade from MM to LP

Hello, yesterday I was trying to downgrade from MM to LP using Fastboot and by mystake I flashed "fastboot flash partition gpt.bin" and it failed, the others commands failed as well, after that I was unable to turn on my device, it only let me access to Bootloader Mode and also shows the battery charging, cannot access to recovery, and it shows black screen when I try to turn it on.

My phone is completely stock, It has neve been rooted, stock recovery. Its a Moto G XT1540.

Is there a way to bring my phone back to life? What can I do?
[Moto G 2015 Q&A, Help & Troubleshooting] Yousvel:
While in bootloader mode, reboot to factory mode, then reboot again to bootloader mode, flash stock lollipop again without flashing partition and bootloader. You should be good.
[Moto G 2015 Q&A, Help & Troubleshooting] JulesSDK:
When I try to reboot to factory mode the screen gets freezed, so, it does not let me to flash stock lollipop, it fails.
[Moto G 2015 Q&A, Help & Troubleshooting] Yousvel:
Press and hold power button and volume down at the same time for 10 seconds and the phone should boot to bootloader. Then flash lollipop without flashing partition and bootloader. You will be good! I had the same problem with you and that's how I solved it.
[Moto G 2015 Q&A, Help & Troubleshooting] JulesSDK:
I upgraded my phone to marshmallow, that's the version installed on the phone. I didn't root it nor unlocked the bootloader, and therefore I don't have a custom recovery. The phone does boot bootloader, and when I try to flash stock lollipop without flashing partition and bootloader, like you said, it only lets me flash logo and recovery, but 'boot' and 'system' fails.

These are the errors:

[Moto G 2015 Q&A, Help & Troubleshooting] maniraptora:
Is there any way to know how did you downgrade? A mini tuto for people without extensive knowledge on flashing?

The process would be unlock bootloader, then reboot in recovery, do a factory reset, return to bootloader and flash? Which commands should be included/avoided from typical flashing?

Thank you in advance! I'm suffering reboots and other problems with Marshmallow...
[Moto G 2015 Q&A, Help & Troubleshooting] acejavelin:
You cannot downgrade with the bootloader locked, it must be unlocked.

FWIW... Pre-flash validation error is bad especially if any other part actually took, most people who get stuck at this point with a locked bootloader, and no way to unlock it (meaning you didn't previously turn on OEM Unlocking in developer options), have no recourse but to send their device into Motorola for repair/replacement. Note that it will return factory fresh with current software release (Marshmallow) installed. Motorola does not officially support downgrading of the system.
[Moto G 2015 Q&A, Help & Troubleshooting] amangurung07:
Let me tell you one thing if you have upgraded yr Moto G 2015 to MM and for some reason you wanted to revert back to Lollipop 5.1.1 you can do that... But remember you need to flash stock ROM with unlocked bootloader..

The time when you upgraded yr Moto G 2015 to MM the bootloader gets upgraded and bootloader downgrade can result in hard brick.

So when you flash stock Lollipop 5.1.1 stock ROM skip flashing gpt.bin and bootloader.img files and flash the rest files and you will be in Lollipop with the better battery life.

---------- Post added at 08:30 AM ---------- Previous post was at 08:26 AM ----------

Yr procedure is correct but the problem that is not allowing you to flash the system files is bcoz you haven't unlocked the bootloader of yr phone..

Unlock yr phone's bootloader and flash again... Sure it will flash all files...

Already did these steps xD

Hello everyone. I first want to apologize for the intrusion and if you all mind have a mod move this thread. :)

ROOT:

There are many ways to rooted MediaTek device. Don't bother with towelroot unless you know some strings and Kingo root mobile app doesn't work. I used the newest version of King Root it works fine. I also bought the app supersu me and it flawlessly got rid of all king root and put on supersu. Took less than 10 minutes total. I'm not going to post to have to because they're all one click solutions the phone is very very rootable.

The latest version of Xposed for KitKat works great installs fine and all the modules I've tried which is about 10 all work fine.

I have a Studio G phone and have rooted it and made a Philz Reovery 6 for it.

I want to share and ultimately port a lollipop rom.

I will be updating this thread throught the coming days.

Thanks.
[Blu Studio 5] nobreak1970:

Wipe system, data, dalvik, cache

Flash Rom

Wipe dalvik once again.

Boot

Enjoy and Explore.

I just noticed that King User is installed. Must have been in the package. Uninstall it and install SuperSU, OR just use KingUser.

This is a KK 4.4.2 Marshmallow Themed Rom, not by me. I just ported it to our device.

EXPLORE THE HELL out of this ROM please. :) It seems awesome. I've done no adding to it except in the build.prop to add our phone model info.

It's not done by a long shot.

Enjoy!

K. I know how it was for others. I would be happy to do thee step by if you wish, or others can message me for it. Happy to see some movement here was going to build TWRP, but not so urgent now. Is the Lollipop rom stock from another device or is it a custom rom? Either way thanks for the hard work with a recovery built custom roms are now much more viable for newbs and casual users.
[Blu Studio 5] commandervadeo:
anychance you could post the rom? its been a few days seience you said you would ask the devs of the original rom.

OTA Update Fail :0

Whats up xda, today or tonight from where i'm at :P. im making this thread because my Blu Studio G D790U Bricked when i did an OTA Update. I've been over the interwebs trying to figure out how and why this had happened, luckily im able to get into the recovery menu just by turning it on. (don't know the button combo to get in recovery) and i was able to find the ROM for this phone which is called BLU_D790_V17_GENERIC_O. and right now all i need is some help on this, hopefully i'm not the only person who had an OTA update problem before with this phone.

[Blu Studio 5] Valued Customer:
Hi. I managed to root my studio g d790 using kingo root, installed su, busybox, rashr, and then this cyanogen mod from op. There are some problems, and I hope I can keep the mod, because lp 5.1.1 instead of kk 4.4.2. The phone, after less than 5 minutes of operating nominally, returns to the boot ani cyanogen scr, and the only way to proceed then is to remove the battery and boot.

I want to clear the data, which I failed to do when I cleared the Dalvik and cache during the installation of the cyanogen mod, in the hope that it will stop this problem. Any body willing to help me figure out how to get this rom working? I'd sure appreciate it =P

[General Topics] Daring:
Hoping one of the brilliant minds here has some idea how to handle this.

I have a VM that contains all of my work data and an Apache phone. Outlook on the VM syncs with an exchange server. Since Remote Desktop does not allow USB connections, I have no way to connect the PDA to the VM. I have no VPN access directly to the exchange server. I do have admin rights on the VM.

Looking for a way to sync data from VM to internet then wifi sync from internet to Apache. Preferably without using VZW Wireless Sync. Any other methods that will work would be fine.

Any ideas?

Thanks,

Daring
