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!

L31C432 , what roms can i flash?

anything that works on the l31, c432 means it's the european variant

So all L31 variants work? Or is there differences in lte bands lets say like 432 and 185 variants ?

You can flash whatever rom version you want.
As most of us, we've installed vns-l31c185/c636b360(latest version of Nougat) and we don't have bugs or problems.
No matter what oem info it has (oem info is the Variant/region of the phone, like c432 is for Europe, c185 is for mena , c636 asia i guess, correct me if I'm wrong) The version will be compatible with your phone.
I don't know if there is differences between oem info of each region , personally i installed c185b360+ the additional package of c432b328 over c432b161,( i was in mm and went to nougat) and i dont have problems with mobile data.

@simo255
Thanks for the answers. Like i said i currently have rooted L31c432b336 and revolution recovery.
If i want to update b360 should upgrade through dload method or twrp?

Via twrp you can flash nougat without changing oem info. If you want to update via dload you must have the oeminfo of the rom you want to install.( So if you are on C432 you can t flash C185 Ffirmware via dload because you havr c432 oeminfo) but be carefull..there arr lots of bricked devicea.

Sorry to rub it, but I want to be sure because I already had troubles when upgrading to nougat.
But....so in twrp I can just flash the bigger (abt 1.2gb) file and its should work? No need to flash second smaller zip?
I have had Sony devices past 3 year and I have used to flash those

Ive ashed the second file and it gaves me errors
Like i did , flash the bigger size and the additional package, take a look at my thread : https://forum.xda-developers.com/huawei-p9lite/how-to/nougat-official-firmware-t3512932

I will follow simo225's instructions.
Now I'm beginning to wonder what is the differences between smaller zip and additional zip, because I thought they were the same :laugh:

From Emui 5.0 to Lineage OS 13?

Hi guys. I've a Huawei Nova L01 with CAN-L01C02B331 and CUSTC02D002 firmware. I want to try the lineageos build published by grarak on his twitter account but some weeks ago i risked to brick the phone (i was already on nougat). Anyone know a safe and effective guide for that? Thanks to those who will help me

You can talk with Grarak on Twitter and ask him how to solve this issue and if it's possible to go back on marshmallow from emui5

already done so, zero response

Asked huawei for rollback link
Same problem here, so I emailed huawei for a rollback link. I'm on NRD90M so normally should be able to revert to original MM... No response so far...

And how can we go back to mm, is there a tool to do it? I have tried to flash mm but I'm not able because system and cust partition are bigger on stock mm firmwares, so once installed nougat we are not able to go back on mm. Basically they have to release a tool witch will automatically repartition system and cut partitions or release a mm firmware with smaller partitions....Oh sorry they didn't respond, I'm curious about they're response, if they will ever replay to you e-mail.

Well, thats whats the NRD90M build is made for, so you would be able to return to MM Its a build that should give the opportunity to have a rollback... However, what I have learned is that you need a specific updatefile to do this... This updatefile, does not exist (?)

I see same thing like in your screenshot on my CAN-L11 downgraded with the TWRP backup.
Is that a problem? What's the purpose of this oeminfo? Can't we get it after reinstalling stock rom?

We need vendor and country for updates, i belive (not 100% sure) we won't get updates because of missing them.

Hmm.
I read that it is related to debranding. E.g.: changing the region to get updates for that region. I'm not sure, but this is what I understood after I read some comments.
But you may be right.
I can't find a proper definition / explanation about what's oeminfo...
Tomorrow I may install stock ROM to check for updates and see if it's working or not.
EDIT:
@mArIuS% , I've created a file named custom.bin in /data and wrote hw/eu in it then I ticked all the checkboxes at permissions (I remember that there was saying vendor:hw and country:eu at begin, before I even unlocked my bootloader).
Now when I call *#*#2846579#*#* again, I can see the vendor and country.

so every CAN-L01Cxxxx FullOTA-MF-PV should be good for re-installation?

You can install via stock recovery only the update that match your phone brand.
C02 is vodafone brand.
C109 should be tim brand.
C432 is the no brand.

[Firmware] Which firmware should i use to update to emui 5.xx with VNS-L31 C432 B226?

My phone had to be repaired last week, and the Huawei repair service changed everything in the phone except for the backplate.
However, I am now stuck with emui 4.1.2 in firmware VNS-L31 C432 B226, and i can't find a replacement firmware for the system.
The phone shows no update available in stock.
I have TWRP and magisk installed atm, just so i could try and get a different firmware with emui 5.1 or 5.0 at least, which I did to no avail.
Is there any way to find the correct firmware compatible with this phone?
Googling this firmware gives me no clues as to the correct path to updating this phone.
Should i use an adb/fastboot command prompt to update it, or use the dload method, or even the extract the SYSTEM.img from UPDATE.app method?
I just don't want to revert to an "earlier" version of the firmware with the dload method just to have my phone bricked.
These are the firmware i tried already:
[TO BE UPDATED]
TL/DR:
I have a Huawei P9 Lite repaired to a stock:
Firmware: VNS-L31 C432 B226
EMUI: 4.1.2
in Portugal.
I want to know a compatible firmware or series of firmware patches so i can get
Firmware: VNS-L31 C432 Bxxx
EMUI: 5.xx
Thank you for your time.

Hello,
it's strange that with an unbranded european firmware your phone didn't upgraded to android 7....
Anyhow i never done a forced upgrade but if i were you i wil try with HWOTA update, like explained in this thread.
So first make all your necessary backups, then unroot and finally follow the guide to upgrade.
P.S.: If your phone is dual sim try install B370, if single sim try with B371.
All the best

I tried a bunch of firmwares for emui 5.1 that didn't work, or which had NFC and bluetooth not working. I ended up downgrading to B160, and am now reupgrading to B370 after checking that both of the previously mentioned are working properly. I will update on this issue asap.
Also, it seems like the firmware I originally had was updated in march 2018, so it was really an updated official firmware with emui 4.1. What a weird setup. Could it be to make sure the NFC and bluetooth would be working? I just don't know...

I did it and it worked, however i flashed the recovery partition of version VNS-L31C432B380 with TWRP and now can't do a OTA update to B388.
Should I extract the recovery img from a b380 FULLOTA update and flash it to my recovery partition with fastboot?

Hey,
surely without stock recovery OTA updates won't work,
so yes try flash it with fastboot, then update to the latest/wanted firmware and finally unlock bootloader,
flash custom recovery and root (even if wanted).
