Hi everyone. There are discussion spread on multiple posts about the problems we should have on downgrading from Marshmallow OTA updated. I created this thread in a attempt to centralize this.
Sounds like the previous Moto Gs (2013, 2014) users get a bricked phone when attempting to downgrade from OTA update to factory firmware and re-update it with OTA update again... This is related to the bootloader being modified by the OTA update. Because of this the recommendation for this devices is not to update their phones using OTA update if they want to downgrade someday.
Well, there are some successful reports from osprey (Moto G 2015) users doing this. Users like @drico_649 and @yea55 successful downgraded their phones.
I'm stuck on unlocked bootloader after a failed attempt to root Marshmallow. So, I need to downgrade my OTA updated to Marshmallow.
The obvious way is flash the factory firmware with fastboot and re-update to OTA Marshmallow but this is considered risky.
What are my alternatives?
Ok, I successfully flashed the factory firmware. Working normally!
But I got a unusual message:

That is this? I did not answer this.
So you can successfully downgrade the bootloader on your device? or did you skip gpt.bin and bootloader.img
The only thing people need to skip is gpt.bin

i swear the bootloader was thing you wernt meant to downgrade? and what happens if you do flash gpt.bin ?

If you flash gpt.bin, it will just fail, but it shouldn't cause anything. But for the bootloader, it will be downgraded with no problem at all.

Download it from here: http://sbf.droid-developers.org/download.php?device=14&file=911
Firmware version: Android 4.4.2
Blur_Version.175.44.1.falcon_cdma.Boost.en.US
Carrier: Boost US
MD5 Sum: 78DEF46FA777AECCC7F7046EF367FBFF
After you download this, please flash the fastboot file using RSD-Lite:
Please download RSD-Lite 6.1.6 from here: https://bitly.com/bundles/johnlgalt/2 and the latest Moto drivers.
Thanks, but it keeps failing at the first step (aboot) which is why I want a flashable version.
Unless you know how to get rid of the "Preflash Validation Failed" error.

Can you show me a screenshot of the error?
No for two reasons:
1. The error is in fastboot mode
2. I don't have a second device to take a picture. I'll try to find the error online.

In this example picture it's from CMD. It produces this error on motoboot, aboot, and fsg.

It looks like it's trying to verify a file and but verfication failed so it will refuse to flash to the device. There is issues with trustzone which prevents the flashing of the tz partition.
But then how can I return it to true stock? I have it on stock but unlocked BL (4.4.4) and I can't find a stock fastboot flash for 4.4.4. I want the BL locked but I can't do that without returning to true stock.

You can flash this file: http://forum.xda-developers.com/mot...o-remove-bootloader-unlocked-warning-t2794104 to get rid of BL unlock warning.
I've done that. But I just want it locked because I'm giving my phone to my nephew for his first phone. I'm getting the N6. He does not know how to root or anything and I don't want to keep it unlocked. He can't access the BL unlock code because it's in my email. He could reapply but he doesn't know how.

As long as he doesn't flash it, the unlocked BL won't be an issue. Try flashing the partitions manually besides the tz partition.
I can't lock it then. I guess it doesn't matter to you, but in the event he decides to try to root it or something all he has to do it flash a recovery. And he's careless. But I guess there's no way to relock it. ?
You can't flash 4.4.2 if you have an up-to-date bootloader.

I have an unlocked rooted 4.4 and need to update to the latest os and modem drivers.
What is the best way and how do I get tethering and root back after I do it?
Pay for sunshine get boot loader unlock flash moto x ROM that is modded
I already have it unlocked.
Where can I get the latest 4.4.4 rooted and can I flash it directly over the current rooted 4.4?
Also where can I get the latest modem drivers?
If you are boot loader unlocked you are already good to go, you can root with a quick flash of a custom recovery

I have TWRP and rooted I need the latest modem drivers and os update
http://motofirmware.center/files/
This site was down for a while, but it seems to be back in a limited fashion right now.
You will need to reinstall TWRP and flash Superuser/SuperSU to regain root after flashing the files most likely. As for tethering, if you plan to stay with a Droid Maxx ROM, you can take a look at this link.

You have to flash that image with RSDLite if I recall correctly. If you leave the xml file the way it is, I believe it will wipe your TWRP and flash the stock recovery in the process, not positive as I haven't done it for a few months. You can reinstall TWRP and root afterwards.

All done, just manually flashed everything but the bootloader.
What are the exact steps?
I have an unlocked boot loader on my Droid Maxx. Currently phone is on 4.4.
Now I am interested in updating it to the latest OTA without losing root.
I understand that if I first install TWRP, I would not be able to take OTA updates. In that case I have to download the update files from the link above and flash via RSD Iite. Is that correct?
Is it not simpler for me to take all the OTA's first (and lose root in the process.) Then, I can still install TWRP and then install SuperSU?
So, yesterday I took four OTA updates and moved from 19.xx to the latest 4.4.4.
I am still rooted and with BL unlocked.
No TWRP ever installed.

My original ROM is NXT-L29C432B320
I installed Nougat AL10, but wanted to get back, so I changed it to NXT-AL10C00B321
It was working well, till I changed it the oem, to install NXT-L29C432B521
Now
I have NXT-C00B380 ROM that is working.
Unlocked bootloader, unlocked FRP
No root
Device has failed verification
Any fastboot command doesn't work. FAILED (Remote: Command not allowed)
How can I go back to my original ROM?
Or
How to root it again without TWRP?

Try to dload B180 or B200 from there you can decide want to upgrade to EMUI 4.1 or EMUI 5 or else maintain EMUI 4.
Good luck.
Unlock the bootloader again even if it say unlocked.

Hey guys, I have SM-G920F 32 GB, which I kinda messed up. Here's the story: I was using custom 7.0 rom and decided to revert back to full stock 6.0. I flashed it with ODIN, everything was fine, until I saw storage field in settings was displaying 16 GB ? Tried smartswitch emergency recovery twice, both times freezed at 93%. Then I started searching for alternatives and I found a couple of another 6.0 multi-file roms, tried a couple of PIT-s, but still 16 GB. Any idea how can I get my other 16 GB back ? Thanks.
Edit: Flashed stock 7.0 and all my storage showed. I think the topic is completed.
New, 22.03.2017: I decided to downgrade to MM, I'm not happy with stock Nougat, but if I got only 16 GB of storage when returning MM last week, now I get red FAIL in odin while attempting to downgrade, tried a bunch of stock firmwares, different ODIN versions, everything. The error is always in the beginning, on sboot.img. Can someone help me to downgrade to MM ? Here's the info about my original MM with which I bought this phone:

I decided to edit and bump this topic, instead of creating new unnecessary one. Any help is appreciated.
flash to latest 6.0.1 with latest bootloader
i think bro you must flash to latest 6.0.1 with latest bootloader 5DQA3 instead of 4DPJG after flash by odin you must make full wipe (format +wipe cash)and i think this will solve your problem because you install nought that have newer bootloader and you downgrade to stock 6.0.1 with bootloader 4DPJG for that reason odin fail at sboot that will prevent you to downgrade old bootloader

Hi,
I just tried to update my P20 from EML-L29 8.1.0.106(C432) to EML-L29 8.1.0.110(C432)-FULL.
My Bootloader is unlocked, the phone is rooted and TWPR is installed.
After the phone has downloaded the update and is rebooting into the recovery I get the following error:
https://ibb.co/hq5hPS

Is this error normal, beacuse I unlocked the Bootloader of the device and the updater will just be blocked by Huawei or am I doing something wrong?
Is the another methode to update the device?
Thanks for your help

It might have changed since I did this the last time (a couple of years ago), but
When running stock firmware, and rooted, I never ever ever applied official updates.
It was doomed to fail. Then.
Today it might be different...?
- I recommend a Return To Stock, by flashing stock firmware. And yes, that will wipe all things on your device.
This is why one always uses backups such as Google Sync etc.
Best of luck m8
