Hello,
I recently "upgraded" to Android 6 and I hate it. Not only do I not like it but my phone is very unstable and reboots and random intervals. Battery drain is also insane, lasting only 1 day.
Please let me know how to rollback to previous Android version. I am willing to donate for an answer that works.
Thanks!

1: make sure you have stock recoveries in place (both "recovery" & "recovery2" partitions)
2: have the stock b029 full rom (links available @xda or needrom.com) in the following folder on your sdcard: dload/UPDATE.APP
Make sure this is the extracted file from the zip, not the zip itself
3: power off your phone, press volume down+up+power until you enter eRecovery mode
Happy flashing
In case your phone doesn't recognize the update package, you can download it directly from your phone:
when rebooting, ensure your phone is plugged in via USB to your PC
No luck, bro. Same as before. Phone checks the file, goes from 1 to 4% and then at 5% (when it says "Installing") it says Update Failed. Reboot now.
Tried with eRecovery also (volume+ and USB cable inserted). It connects to WiFi but can't find any package.
I think the only option is to sell the phone and buy a new one with the factory firmware.
Lol, that's not the only option. Download Huawei firmware extractor, extract boot.img, recovery.img, cust.img, cache.img and userdata.img from the B028 firmware (not b029)(you can skip system.img). Use adb and fastboot to flash those files. After you flashed then repeat the firmware flash procedure with firmware b028 in dload folder and vol- vol+ and Power buttons. Did a rollback several times, worked every time for me.

Also here is a more detailed description:

My phone is pure stock. No root, no bootloader unlock, no nothing. Will this still work?

You need your bootloader unlocked. You can use dc-unlocker to do that. It will cost you 3$ or 3€ and 10 minutes of your time:

Still more convenient that reselling the phone.
I was hoping that wouldn't be the case. But I guess there is no cure for stupidity, since every time I "upgraded" my phones ever since the Galaxy Note N7000 got Android 4, they always ****ed it up, every single manufacturer. They're not at fault here, I'm the idiot who never learns his lesson.
So yeah, selling my phone it is since if you unlock the bootloader, you lose the warranty and that will make my phone sell for dirt-cheap, since I cannot use it with Android 6.
Thank you all for your help but it looks like this is the only option.
The first chance I get (someone makes a similar-sized device) I will abandon Huawei. Hardware is great but the software is utterly horrid! No-name chinese phones have much better software support than they have.

Unlocking the bootloader doesn't invalidate the warranty, so you're good to go. I for myself love the P8 max, hardware and software. The B029 works extremely good for me after customizing it a bit to fit my needs. There is no reason for me to update to Android 6 since everything works so flawlessly.
If you want to keep the size and don't go any smaller, one of the acceptable alternatives is the Asus Zenfone 3 Ultra, even thou I prefer the design of the P8 max.
Unfortunately, in my retarded country (Romania) I have to call Huawei to get the bootlocker unlock code, which by their terms in this ****ty country, invalidates the warranty. I've been through this nightmare before, with the DAV-701L in which I had to call in UK to get an unlock code, which they even said that I will lose the warranty.
These guys ****ed something up because, here's the kicker : you have to get the unlock code FROM Huawei, which invalidates the warranty. But to invalidate the warranty, you need permission from Huawei. **** logic.
The Zenfone is looking mighty delicious, you know. Thanks for the tip!

I must admit that I'm not overhappy with 6.00.
In exchange of a few new feature I lost root and things aren't so smooth anymore. Gonna roll back as soon as I receive my Xiami Max as a backup phone. Asus Zenfone 3 Ultra will be my next buy, but waiting for a phone so long it's a pain in the ass.. they shouldn't announce models months before they can release them. Like HP Elite X3 (January and just coming to shops) or LeTv X910 (which never saw the light) ?
hi guys,
I apologize for resurrection of this thread but does anyone know the location of the stock b029 full rom file ?
I do remember I was running MM and I want to give my P8 max to my niece but unfortunately it's missing OS.
I could install twrp and I was searching for the file but the links are dead and I think this would be the best place to ask.
Anyway, thanks in advance and sorry for bumping up 2 years old thread.
Peace

I flashed it 8 days back and I am using it daily. I didn't face any issue. everything works perfectly fine. but make sure to lock the bootloader after flashing the ROM or else you will get warning when rebooting the watch.

Does it keep it up to date? I had an update come through for my watch 2 pro the other day and now I have a rather cutesy Chinese new year background I can rotate as well as additional tips and much better functionality.
my main reason for wanting to flash it is I want the Google support
Could somebody direct me which ROM to flash and a bit guidance if possible.
I have:
Huawei Watch 2 PRO Chinese version and want to flash it to English
LEO-DLXXU
Huawei-Watch 2 0380
I have the same issue with my newly bought HW1. I can't get it to work with my computer. I set it to ADB enabled, but still the pc isn't able to see the watch. I can't find it in 'devices'.
I could use a little bit of help as well. I tried to get it into fastboot mode, that worked, but my pc just won't see it...
It is still locked
Huawei Watch 2 Pro has the same codename as Huawei Watch 2 4G (sawshark) and can work with such ROMs.
I was able to unlock bootloader, flash TWRP, the ROM and the Kernel via fastboot. As I got the watch recently and it was already on Oreo, there was no need to flash the bootloader. I recommend using the odexed version of the ROM as the deodexed version was too slow to boot or run.
After flashing I'm able to properly pair the watch with Wear OS from Play Store, although you will still need to register a Huawei ID if you need to take advantage of eSIM connectivity.
Again, you should only flash if you have already backed things up and have ways to recovery from failures (inability to boot aka brick) in case things went wrong. Also, you need to boot to system a second time to let the data partition reinitialized, when you unlock the bootloader.
Hi, what happened to your "Huawei watch 2 PRO" matter ?
I were able to flash the rom to my pro 2 without any issues.
NXG46W works fine on my Huawei watch Pro (e-Sim)

I can confirm that the 4g NXG46W from from https://forum.xda-developers.com/watch-2/development/rom-huawei-watch-2-4g-l-09s-global-t3602205 works perfectly on Hauwei Watch 2 Pro Leo-DLXXU model. After flashed (without flashing the bootloader) the watch works fine and 4G connectivity is right there on the watch's menu and on the Huawei Health app on phone. However I cannot test the eSim connectivity as my operator is net yet support the eSim on watch. After rom is flashed, the watch did OTA update 3-4 times, now the latest rom on my watch is Oreo with build number OWDE.180215.017
Hope this helps.

Hi mohamed cheikhna, I am in the same situation. Did you get any feedback about how to do this?
I have gt neo 2 global rui2, and can't get to fastboot. Deep Test APK doesn't work, maybe I have wrong APK, but tryed a lot of them. If there any practical advices, it would be great.
Certain variant doesn't allow it. Me personally bought Malaysia variant and deeptest always fail. From searching it turns out realme have locked carrier region for certain country phone. Really sucks, bought this phone expecting to be able to flash custom rom later but realme decided to do a surprise butt **** on me. It's just so weird, any other phone brand doesn't have this, just realme.

My Redmi Note 7 Pro has a network problem, always shows no service. I have already tried fixing it in the Official Mi Care but failed. I want to use this mobile for the experiment so I need root. But without Mi Unlock Status I can't find any solution. Do you guys know about any unofficial or another way to root or unlock the bootloader without a network?
same problem happened to my redmi 4x (santoni) in 2019,
no cellular service or connection after flashing some roms,
still the problem continues,
i know what the problem is, in 2022 but at that time i already have the new phone.
i think your IMEI is blocked mate.
I tried to flash Global ROM to Chinese Redmi Note 11E Pro 5G, but when flashing unintentionally ticked "flash and lock" option. Now my phone is stuck in Fastboot mode, and it doesn't allow me to neither flash other ROMs nor unlock using MiFlashUnlock.
I searched how to fix this in Internet, but unfortunately didn't find any solution - every option requires me to unlock bootloader with a functioning phone, but unfortunately that seems not possible in my case.
Is my phone bricked?
Any way to bring it back to life?
Basriy, if you are going to use this route, could you please report whether it was a success?

I would love to. In fact, I have contacted that guy from Telegram and I genuinely believe he is capable of solving my issue. The problem is I couldn't make a payment to his account to finish his job because of financial restrictions at place.
So I think I have a fancy looking brick now.
i have the same problem , on my Note 11E pro , stuck on fastboot , any luck ?

The guys who repair phones in my town found to be able to fix this kind of a problem as well, but that required physically opening the phone and doing some programming.
And I am still waiting to get help from them. 3 months have passed. Pinged them ~20 times. Each time there's either no answer or a single Yes, but when I give them the connection details, they go completely silent.
