Upgrading from B170 to B313/Downgrading back to earlier version

Hi guys,
New to the forum here. I've flashed B170 a while back to get the most stable Lollipop edition, but I'd really like to try Marshmallow. The thing is, I can't figure out how to downgrade it back to B100/B121/B130 or to Upgrade it to B313. Is it possible to do either of those two things without an unlocked bootloader? There doesn't seem to be a way of flashing any packages on the phone, so I've sort of resigned myself to having to flash it via adb, but is this possible when I don't have an unlock code for the bootloader? Thanks for any help; I've really read through all the threads, but I couldn't come up with an answer.

Hi !
In order to upgrade to MM, you will have to downgrade to an upgradable version like B140. All the things you need are in the MM Upgrade topic of this forum.
In order to rollback from MM fo Lollipop, everything is explained in the same topic but you'll have to download a temporary system (B300) and then you'll be able to downgrade. Anyway, everything is in the MM Update topic.
I don't think you have to unlock bootloader to do all that but it would be easier because you would be able to use Honor 7 Multitool which is a software that does everything for you in no time
Good luck (MM version of the Honor 7 is awesome !)

Thanks for the reply! However, you can't use the B300 rollback on B170 (which is a Lollipop rom), can you? I've read the Marshmallow topic, and I was none the wiser - I can't seem to figure out if there's any way to get back to an upgradable version without flashing with the Honor tool (which requires an unlocked bootloader, non?). Sorry for the n00b-factor!

so many treads around here described the solution to do! Please use the search engine too
read following from there: http://forum.xda-developers.com/showpost.php?p=64673136&postcount=74
and...
try to flash the B313 Rollback file first!
Maybe it will stop with "not successful!" nearly ~93% but THIS DOESN’T MATTER! a reboot should bring you to interim B300. Then you should be able to flash the B121 Full update out of your dload folder from your internal SD. If this work, you should be able to update to B313. You do not lost your personal data, but make a backup to be sure!

The guide from Controllerboy works perfect ( advice read it more than once ) , the axontoolkit works too.
If you decide to go with custom rom you will loose ZTE Dolby,
but viper works good, but there are debloated stock roms which you can use with Dolby and root.
Unlocking the bootloader is always helpful, if you decide to use custom recovery and root, because if you mess up anything you're mostly lost with a locked bootloader.
Unlocking the bootloader will completely wipe your phone, better you copy your important stuff to PC.
If you just want to update your phone copy the latest official
firmware to the external SD card and use the update function.

This is a bit outdated, you can follow the guide on mm or n, doesn't matter. No need to down or upgrade before.

After you did the unlock, the twrp update and flashed the Los thread bootloader + modem you can use this rom, guess this is what you want:

@am2006 it seem strange that you don't receive OTA update. It is seem that the seller had done something with the phone (properly install A2017G on A2017 chinese model). Before doing anything, you must know you model, cause A2017G brick is pretty hard to fix

I recommend using stock Nougat. Stock ROM has pretty good camera, Dolby, DAC which you will missing when using custom ROM. (Stock MM is bit crappy, ZTE has fix a lot after several update).
Beside, RR is very good custom ROM.
Official Xposed does not support Nougat yet, there is an unofficial one but not work with stock Nougat, I haven't try on RR

There are multiple iterations of Dolby made as a Magisk module. Magisk works perfectly on both LineageOS and Stock rom.

How to rollback to stock?

Hi there, im currently on the leaked oreo beta on my A2017G but since this month there should be the official oreo out i wish to rollback to stock. Do i just need to flash latest rom on it? Do i need to relock the bootloader and remove twrp to get new ota updates?

Checking bootloader version on the phone

Hi, how do I check my current bootloader version that is on my phone? And how do i know what version of bootloader will be in any stock rom i want to flash?
I don't want to overwrite with older bootloader. Need to know the current and the next one i will flash.
My device is from Europe and I have NPN25.137-92 installed.. I think this is not the latest stock nougat for my region.
Cheers.

No need to push your question everyday. If someone is able/wants to answer he will do.
First of all: NPN25.137-92 is not the European firmware, it's the one for India and Brazil.
The latest one in Europe seems to be NPN25.137-93-14, since yesterday there is another update with version number NPN25.137-93-18 out incl. August security patch but until now only US users (software channel RETUS) have confirmed it. For India/Brazil (your firmware) the latest Nougat firmware is NPN25.137-92-14.
Have you fastboot flashed some firmware on your device so that you are on NPN25.137-92 now? That could be the reason you don´t receive any further OTA updates.
Your bootlader version should be visible when you boot into stock recovery.

Yes, I must have flashed pretty wrong firmware, and now I want to get back on the track. Though I dont remember and I dont have knowledge what was flashed before that. Now I wonder what should be my next step in order to have latest European nougat, or oreo.

Flash latest european firmware NPN25.137-93-14 via fastboot. It can be found somwhere here in the Moto G 5+ threads or you can download it with Lenovo Smart Assistant: https://support.lenovo.com/de/de/downloads/ds101291
That should keep you back on track.
If you can't wait you can update to Oreo with the available OTA found here:
https://forum.xda-developers.com/g5...fficial-moto-g5-g5-plus-t3848246/post77856408 ( Read OP of that thread to find out how). But as I posted above there's a newer nougat firmware out in the US so you may not receive future Oreo updates if you use this OTA.

Need an advice: I'm currently on POTTER_NPNS25.137-93-10, OTA says i can update it to POTTER_NPNS25.137-93-14.. Then I could get Oreo OTA from the thread above. In case of any further trouble: will it be safe to return to nougat POTTER_NPNS25.137-93-10 via fastboot? If yes, if then I update again to POTTER_NPNS25.137-93-14, it is safe to take nougat OTA again? And then oreo OTA again? Hope you get my point.

No, that's not safe. Downgrading is always a risky thing because of the bootloader and taking OTA after that could completely hardbrick your phone.
So if you're once on 93-14 you shouldn't flash an older firmware than this. Same applies to downgrading from Oreo to Nougat.

Well, in case of firmware, I cannot find direct 93-14 fastboot rom for download. I have found 93-10 only, that's why I'm concerned about not having the most up to date rom version on my hard drive to flash in case of<>.

Thank you. What in case I'm unlocked and in order to use google pay I need custom recovery and flashing magisk. How do i get back to stock oreo recovery then? I know it's a bit of offtopic, but maybe you can help me.

bootloader unlock Can You Receive Updates via Ota or No?

I am curious about these issues, my question is the following when I unlock my Bootloader I can do an update via OTA when it arrives on my device? Or is my phone going to have Hard Brick?
I want to give a Downgrande on my smartphone but it is still in stock without any modification. And through the tutorials I read ask for the unlock Bootloader. My intention is to only downgrade. A friend of mine gave the following idea: "unlock the bootloader to then downgrade and after it has been successfully done." I search how to lock the bootloader again using CMD to put a system with the bootloader locked and so in the future I will be able to receive updates via Ota. " Does This Worker Ideas In Practice?
This my Frist Post here If I make a mistake, tell me, we will not repeat.:fingers-crossed:

When it comes to being able to receive updates when bl is unlocked, that's a yes, it will work fine and won't affect your phone's functionality.
On the other hand downgrading is generally a bad idea. The problem is, when you update your phone your bootloader also gets an update. All parts of the OS except for the bootloader can be downgraded to a previous version, and if you do that, the downgraded OS can function normally on the newer bootloader.
Now comes the tricky part. If you try to do an OTA on a downgraded OS with a new bootloader, the OTA will treat the bootloader as if it were the old one, and will overwrite parts of it that it shouldn't, which will corrupt it. And there you have a pricey paperweight.
The only way of updating a downgraded device is to flash it clean with a newer version (or the version same as the bootloader).
Now what is the reason you'd want to downgrade?

My bootloader is unlocked.
I wanted to upgrade to the latest firmware and because I was rooted I flashed the firmware I was on at that moment (no down - or upgrade) again and after that I was able to apply and install every single OTA up to the latest. I could have flashed the latest Oreo firmware directly too but I wanted to test this way and to update by flashing latest firmware would have been possible after that too.
So updating via OTA with an unlocked bootloader was no problem for me.
In the end you get the unlock code from Motorola itself and it would be kind of strange if they won't deliver updates anymore for a feature they provide for their devices.

I am planning on to unlock bootloader only will I continue recieving official updates from Samsung and able to install them (not flashing that, OTA ones). I am not going to install custom recovery or kernel or even custom rom. Will it work that way?
