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!

p9 lite bricked, i need the b125 full!

I have installed the b161 update nobrand on my vodafone p9 lite, now i can't complete the initial setup, i searched for the vns-l31c02b125 full update, but i found only the ota, someone can help me?

I had the same problem last weekend,

Downside is that you'll loss root and all. I hope you have a backup.

How big was the update it should be 1.99gb and if you didn't do it the official way (very few people got it and you'll have to wait if you want it) then you need an unlocked bootloader and twrp to update.

Ok, but what do you have to do?
Download B336 to B370 faild
Going through TWRP does not work ...
Is it necessary to return to B160?
I read all the forum and nothing to do I did not find ...
Thank you

If you are on 201 then you should go to an odd number version. So is 371 available?
I use Firmware Finder, from the Play Store, and that tells me whether the software is approved for installation, by checking my IMEI.
ETA: Sorry for resurrecting this, I got confused thought it was a current question.

Okay sounds cool I'll rebrand the question remained is what brand has the latest update?(Please provide a link to .zip update) and the last question is,if I rebrand before I install oreo what exactly happens I turn on my phone and it has a frimware from Africa but its brand is now China!Will that be able to turn on?Or I should use TWRP to install Chinese firmware from SD card.

Since I'm an android developer I need to have multiple os if possible.Has anyone tried this Or any better one?Can I use it in this case?

So I'll go to marshmelo of my region and then rebrand and then install oero the only question left is in the process of rebranding do I need any network connection or it's offline?I don't have stable network and I'm afraid terrible things happen.

I download B200 tried to install via dload failed said (incompatiblity with current version ) tried with twrp failed.And I wiped my OS and tried again and failed.And lost my OS.Sort of now it shows me android logo instead of huawie logo and it's stuck on the initial setup of nougat.
https://forum.xda-developers.com/mate-8/general/guide-how-to-downgrade-mate-8-emui-5-to-t3515202
I found this and it says the nougat version must be b500 but mine was b560 and tried to install the rollback and it failed again.I don't know what to do?I need my phone.
Couldn't find any download link of b500 did you do that on your b500 or b560?
If b500 please give me a link of NXT-L29C185B500

Tried again and it didn't give me error this time the point is that it doesn't run on B500 it makes your device B500!

After installing marshmellow the bootloader is locked again!
