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 (?)

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This is a bit outdated, you can follow the guide on mm or n, doesn't matter.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.

Back to stock ROM. How?

Hello guys,
Im using an ZTE Axon 7 with unkocked bootloader, rooted, and using a custom ROM and twrp. I **** to try the original and latest version of the official ROM to see how well the performance are. Is there a package for this that can be installed using TWRP and after it has been installed, my phone is in the original state again?
I saw an update on the ZTE website from 25/07/2018. (Version B35) Is this Android 8?
https://www.zteusa.com/axon-7
Can I install this package by using TWRP aswell?

Flash a zip package in twrp. But flash an twrp image after the rom. The stock rom overwrites the twrp with stock recovery.

Thanks! So, no matter wich bootstock Im using, I can just install the zip from te ZTE website using TWRP and that's it?
EDIT: on the website, there is only A2017U model. No G or A. Does this matter?

That is also an option. But I still prefer the latest version from te website as I hope that this is Android 8 and want to really have it at factory stock again.

The B35 (U-version) is 7.1.1
Try this : https://forum.xda-developers.com/axon-7/development/rom-slm-dfnr-t3744388
It's totaly stock or at least derived from the B35 that you want.
Or make your day and try this 8.0.0 : https://forum.xda-developers.com/axon-7/how-to/official-beta-android-8-0-0-v2-10b12-t3797085
Beta, U version based but definitely worth a try
Or go back to factory with the @djkuz EDL Tool. The B35 is in the OP. https://forum.xda-developers.com/axon-7/development/axon-7-edl-tool-flash-backup-restore-t3750759

B35 (from that site) is Nougat, not Oreo.
Oreo was not released officially so you won't find it in the ZTE website.
The current release (B12) is a -buggy- beta and missing some features. It's really not worth it. Battery life is atrocious (probably less than 2hs SoT).
You're better off with B10 (latest for A2017G) or B35 (latest for A2017U).
Those are the latest official firmwares for the phone and both are Nougat 7.1.1. Pay no attention to the numbers, as B10 is identical (update wise) to B35. Flash whatever you like. There's really no other option.
If you prefer the original stock experience with nothing touched or removed/added, you will have to flash a firmware via EDL mode. But that way you lose TWRP unless you replace recovery.img with a compatible TWRP version before flashing with Xiaomi Flash and your device is completely erased.
Forget about Oreo for the moment.

The post says this version is QPST compatible.
Even on 4pda ZUI 4.0.186 QPST flashable version exists.
I thought QPST and QFIL were basically same, are they different?
If you have it downloaded, could you please share it on GDrive or any other way?

A QPST rom is for using with QFIL
I never used ZUI and do any OTA updates on it, but I downloaded the rom, open the zip file and inside is the normal structure for a regular rom (META-INF, boot.img, system.img files)
I didn't know that there's a QPST version of ZUI 4.0.186 for use with QFIL (downloading rn to check out)
As for the ZUI 4.0.199, sorry I deleted it after finding out it's not qpst version
Edit: the ZUI 4.0.186 qpst I found is an older version patched up with the newest boot.img and system.img files from the newer ota release
The newest official ZUI QPST version I can find is 3.5.386, and it's from an official lenovo cdn server

Hey thanks. So I guess OTA can be used to upgrade to the latest 4.0.199 after flashing the 3.5.386 QPST version.
I am currently on the ZUI 2.5 (Nougat) Indian version, and as far as I understand, to make Oreo and Pie Custom ROMs work properly on my phone I need to upgrade to the latest ZUI to enable the treble support due to the new bootloader and other partitions. Please correct me if I am wrong.

EEA 10.3.30 to 10.3.2.0 = anti rollback brick?

Hello.
Hope you can help because I'm kinda confused atm
My device is redmi note 7 lavender, came stock with EEA (european global) rom.
I recently unlocked the bootloader, installed twrp, tried a few roms (xiaomi.eu, crdroid, phh-treble gsi, etc). Currently using crdroid without issues.
Previous to all this I was using stock EEA 10.3.2.0 firmware and then sideloaded ota for 10.3.3.0.
According to this post this phone has ARB
What I'm wondering is if I were to go back to stock firmware, would I brick my device? Because the only available fastboot version for EEA is 10.3.2.0 which is older I guess, but I'm not sure exactly how ARB works and it that would trigger it.
Thanks in advance

I recommend that you do not return to the previous version, sometimes the ota bring changes in the bootloader, and you can leave it hardbrick as it happened with several Motorola, even with devices that have a Qualcom processor. Expect that someone else has done it or that the software is released to an equal version.
start to investigate the changes that were added
I leave this link you fence to interest move from the EEA to the global version

If you're asking specifically about turning back from 10.3.3 to 10.3.2, then there is no problem (I went from 10.3.3 to 10.3.2 to 10.3.3 again and everything is ok).

Rolling back firmware only through twrp, trying to get previous drivers for international version which bug less on proximity sensor.
As the phone is unlocked I might have found a way to restore from brick without physically opening the phone. Will keep you updated.
Edit/Update: yipeee!!
Need to completely flash the phone based on the procedure detailed here. And reflash whatever custom ROM afterwards as you get back to stock.

Just rolled back from Global 10.3.5.0 to 10.2.7.0 with MI Flash Tool (fastboot rom type). 0 problems, seems you can rollback from your MIUI 10 ROMS of the same version(EEA with EEA, Global with Global, etc, and of course that these roms have same ARB 4), at least worked for me, posting this future records.

Actually firmware tool (as opposed to twrp) is the way I reset ARB.
