Hi all,
I am using xt1643. I installed nougat sock test rom and it is not providing options to update to final nougat rom. Current build npj25.75-2
I read in a thread that downgrading can cause problems. So, what should i do: downgrade to marshmallow and then upgrade via ota or directly flash final nougat rom??
Thanks in advance.

The 75-2 soak test update is a dead end unless you were on the official soak test program. I've not seen any further updates captured to allow you to formally upgrade via OTA to the official Nougat (currently build 93-14).
You could explore either option though:
1) Downgrade to MM, do not flash gpt partitions or bootloader (omit those commands) - you may find a signed stock ROM here: http://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1643-updated-signed-t3460695 (and the associated guide for downgrading: https://forum.xda-developers.com/moto-g4-plus/how-to/how-to-downgrade-nougat-to-marshmallow-t3487201). Then update via OTA to Nougat. You may prefer this to ensure that your update comes directly from Motorola. EDIT: note this method will void your warranty.
2) Flash via fastboot/RSDLite either the 93-11 Nougat update (v7.0, Nov 2016 security update) https://forum.xda-developers.com/moto-g4-plus/how-to/android-7-0-install-nougat-official-t3531612 and update to the latest version via OTA, or flash 93-14 (v7.0, Dec 2016) https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369 This option is the more direct/less potential for things going wrong, it's up to you how much you'd trust the updates you flash. EDIT: This method does not appear to void your warranty.
With either option, back up your key data and be aware your settings and personal data may be erased in the process. Personally, I'd suggest a full wipe to limit the number of issues that may arise. Good luck though
You can now flash full stock roms with (the right) TWRP:

It appears to be the same method as one of the 93-11 methods I posted above: https://forum.xda-developers.com/moto-g4-plus/how-to/android-7-0-install-nougat-official-t3531612
Just bear in mind with using the 93-11 update to install it in India or somewhere we know that particular firmware has been released (and thus has an upgrade path to the latest 93-14 firmware) or download this 93-14 OTA update once you've updated to 93-11. https://forum.xda-developers.com/moto-g4-plus/how-to/ota-zip-update-npj25-93-14-t3539407
Thanks for the help....Followed the other link and successfully upgraded to Nougat full build 93-11 and then updated using OTA to 93-14.
Hello,
Can I downgrade completly with the bootloader on Marshmallow and then upgrade to Nougat?
I want to lock my bootloader.
My G2 bricked after doing this. But I don't know if this would happen to my G4 Plus again

If you wish to simply re-lock your bootloader, the easiest thing is to flash this fastboot stock ROM (which is Nougat) and use the locking script as directed in the first post. https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369 Of course, this may wipe your data - so back up, and the relocking may or may not work, in which case you may have to wait for a more up to date fastboot stock ROM to become available.
If you were to downgrade to Marshmallow, you cannot downgrade your bootloader and GPT partitions, at best, your existing bootloader would try to prevent you from downgrading those partitions. At worst, you'll brick your device again if you were to flash those - though we've got possible ways of fixing that, it's not a route I'd want to go down. Flashing the rest of Marshmallow is no problem, however, ensure you have the correct MM firmware for your device and territory.
Will this version work for my country(Germany) without OTA trouble?

Should be okay to flash - the 93-14 build appears to be the global build that was deployed by Motorola, and should be eligible for the 93-14.4 (March 2017 security update) whenever that arrives in the EU/UK I've flashed the stock ROM onto my XT1642 several times without issue.

THANK YOU IT WORKED AND THE WARNING DISAPPEARED. I am on Nougat, locked and its working like a charm
I WOULD KISS YOUR BUTT IF ITS HAVE TO BE
Hello,
I have a ZTE Axon 7. I have not received the OTA update to Android 7.1. Just now, I am on 6.0.1 (ZTE A2017GV1.0.0B08). My device has only the stock features (I have no unlocked anything).
So, my question is, which is the ordered and simplest steps to have a phone with a stock ROM (updated to 7.1) and with Bootloader, TWRP, and root?
I would like to maintain the stock ROM in order to use Google Daydream and Maintain an acceptable quality on Camera and Audio. I heard that LOS have some issues on these aspects.
Thanks,
youngz89
https://forum.xda-developers.com/axon-7/how-to/guide-install-twrp-unlock-bl-flash-t3517379
follow this guide until B
then, reflash stock recovery, upgrade your phone with ota.
after that, reenter edl mode, and flash twrp 3.1
look that the first twrp you flash is only to unlock, its signed and dont work. so dont keep it.
I use aosp extended, works really good, no manual camera unless you flash stock, sound works good

Or you can just use my toolkit which does it all for you https://forum.xda-developers.com/axon-7/development/tool-axon7toolkit-t3573108
Bkroes, using your tool, you suggest to update at nougat and, after the update, unlock the bootloader and root the device?
I have not received the OTA update, so I am thinking to update with FOTA.

Download the 7.1.1 zip and put it in the sd, then go to updates
Yes, but can I unlock the bootloader and root the device after the update? Or I have to unlock the bootloader before the update?
Where you able to do it?
I was in B.05 version (the one of the 14-4 update) and i flashed the (soak test?) -11 build, with bootloader,partitions and everything, i was hopping the bootloader didn't flash (like always showing error) , but it did,it flashed the bootloader, and now i'm in B0.3 version, and the phone didn't brick, i thought it wasn't possible....!!
I'm happy because i was looking for a way to downgrade the bootloader, but i never thought to do it like that.......
What do you think??
UPDATE: NOW, i flashed Marshmallow firmware and the bootloader downgraded correctly. i have had flashed marshmallow before, and it gave me an error, but now it flashed and now i'm in B0.0E version....
HOW?!?!?
If it's the 93-11 build, that's not a soak test - that was the first of the official Nougat updates (though only formally released in India if I recall - so in other territories you may not get any OTA updates).
Regardless, as I understand it, downgrading your bootloader may not brick your device - what may brick your device is downloading and updating via OTA updates subsequently.
By the way, what was the reason for wanting to downgrade your bootloader? If you wanted to downgrade your system, you could have just flashed Nougat or Marshmallow, just not flashing the GPT or bootloader partitions.
The reason is that i want to update by ota from marshmallow to nougat to get a smooth nougat, because if i flash it with fastboot it has got a lot of lag (i don't know why, but is very noticeable)
I just updated from 6.0 to 7.0 (-14) so it really downgraded the bootloader.
So if someone else want to downgrade the bootloader, you can flash -11 bootloader!!
Update. Again; flashed marshmallow firmware and bootloader downgraded too. What is going on??

Fastbooting Marshamallow will include Bootloader partition by default--you have to skip bootloader flashing to NOT downgrade bootloader. N bootloader will work fine with Marshmallow.
Now i updated to 14-8 version (B.06 bootloader version) (June patch) and i CAN'T downgrade my bootloader anymore, even flashing -11, marshmallow, or any other firmware.. Strange

Possibly to prevent users from downgrading and opening up the security vulnerability that was patched in the May 2017 security update. https://alephsecurity.com/2017/05/23/nexus6-initroot/ https://www.xda-developers.com/moto...a-root-shell-patched-in-mays-security-update/
At any rate, seems that other users trying to downgrade their bootloader from B1:06 hard bricked (and the blankflash we have doesn't appear to function). Be careful.

I tried it, and now it just seems to have become a paperweight from the june patch.
As you mentioned the blank files are also not working, what should I do now:crying::crying:

Oh!! Thank you, now i understand everything.... Thank you man!
Since 7.0 came to the s7, I have been keeping up with the monthly updates the carriers push out but for the past couple of months I've been getting some terrible kernel wake locks and I've tried everything possible to prevent them but I can't find a solution. So my thought was downgrading to an earlier 7.0 where I didn't have that problem.
Now my question is: Has the bootloader been updated prior to the first 7.0 monthly update (march)? Because I've heard once the bootloader has been updated you can't go downgrade to an earlier bootloader and I've experienced a soft brick on my s7 edge while tried to downgrade to an earlier version of marshmallow and someone told me it was because of an update to the bootloader. The firmware i'm on now is G935W8VLU2BQH1 and I want to go down to G935W8VLU2BQB6 which is the first nougat update (march)

Well, I downgraded from 7.0 to 6.0 but with twrp, so maybe it's not possible via odin, but I flashed many times nougat via odin, from april to february security patch, it always worked..

So then it's possible. As long as Samsung didn't update the bootloader between March and August then I should be good. Did you include BL in Odin when you downgraded to an earlier security patch?
