[GUIDE] How to install EMUI 9 / Android 9 Beta on EML

Hi,
you want to flash EMUI 9 Beta, are FRP and bootloader unlocked and rooted? Great, here we go.
Disclaimer: I am not responsible for your bricked devices. This has only been tested by a few people with Windows 10 and EML-L29 C432. Other models may or may not work. Please don't use that method if you don't know how to recover your phone from a bricked or semi-bricked state.
It might be a good idea to disable your antivirus if you run into warnings. There is no root.
Steps:
- Download THE TOOL™ v0.2
- Download the matching firmware bundle for your device. With EMUI 9 the firmware files for L09 and L29 differ.
- Extract THE TOOL™
- Extract the firmware bundle, you'll get two ZIPs and some XMLs.
- Start FLASH.bat inside of the extracted tool folder - it will guide you through the procedure.
- I did not have to factory reset. Maybe you will still need to.
- I have no idea if you will be able to receive OTAs or upgrade to future builds.
Disclaimer: Its not my fault or my responsibility if you brick your phone. I have almost no spare time at the moment, so I will probably not be able to help you. Also, there is no root.
Download:
EML-L09 C432 - Build 9.0.0.47
EML-L29 C432 - Build 9.0.0.45

- @Pretoriano80
- @shimp208 for the bundled minimal ADB + Fastboot
- and of course to all the brave testers!
There is no root. Also, please don't blame if your device dies. And I don't know if VoLTE works.

Which model version do you have, C432?

yes c432

Will this work by sideloading the firmware with ADB (without root and unlocked bootloader)?

my phone is locked. So I don think this will work for me.

VoLTE works perfect!

No su message
The script always end with this no su error. I don't get the permantly grant root message.
I tried the script several times. But everytime the same error....

Any new info on possible root with this? Or do we have to wait till the full EMUI 9 release for that?

one way only huawei service center and flash by test point or all time update from funkyhuawei.club I have sam case

I already unlocked my bootloader and currently rooted on EMUI 8.1, got everything I need to do it with Android Pie. I've been looking into other ROMs like Lineage and AOSP, but I haven't found any good info for the P20... Only for the P20 Pro and Lite, which really sucks, it feels like the normal P20 doesn't even exist, a lot of forums only have subs for the Pro and Lite, it's very annoying.
What is stopping me, or anyone that was lucky enough to root before Huawei stopped that, from rooting EMUI 9? I don't have a lot of experience with android and roms so I'm kinda fuzzy on details.

Morning,
All is alright but... it is not possible to root p20 (some people explained same like genius but i'm not genius)
Where is the best method to root huawei p20.
Thx in advance have a nice day

Got it right. Used these files with instructions on OP

You must be on stock emui. And rooted. So first flash back your stich system.img en stock recovery. Then follow the tutorial in the OP.

Open beta general help

Hi. So I'm a new op7t owner and came from the op5, I'm familiar with stable and open beta versions on the op5 but this is not the same on the op7t. I have attached my info screen which is the version the phone came with so it may help to answer my questions,
When I try to install the open beta 2 from the official op pages it's saying the open beta 2 is a downgrade so I can't do this... however there is no ob3 or ob4 for me to install on the official web !!
Ob2 is the only version download available and also the stable version on the official op is an older version too to what I have now.
How am I supposed to switch over to the beta when it's only showing ob2 and Where are the ob3/4 versions ?
Very confusing compared to how easy switching from beta to stable and vice versa was on the one plus 5 !
Any help is appreciated ?
Regards

Thanks for responding, is this an official updater from OnePlus ? Excuse my ignorance but why would this be any better than the official oneplus software update pages ?
Thanks

The issue is that you have an EU handset likely with EU firmware if you haven't messed around with it yet.
For whatever reason EU updates are pulled back and regularly get behind the global and Indian versions.
I have absolutely no idea of whether there are issues introduced by flashing global firmware but I have had to do so today in order to get to beta 4.
So you have to download Oxygen Updater, go to advanced settings and change your phone to Oneplus 7t (not EU - this will switch to global), switch download option to full beta, download it and flash it as a local update.
There is absolutely no documentation or answers from OnePlus regarding the differences between firmware versions from what I can see.. only speculation from those whom have delved into the update packages and users whom have noticed subtle differences.
Long story short, if you want to try the betas you're better off switching to global at the moment.

I don't know why they don't update their website. I guess the easiest way is the updater app.

Thanks for the replies, very helpful. I just can't understand how I'm on a higher version that is actually listed in the UK official support upgrades pages !

Because the website for whatever reason hasn't been updated.
The latest stable EU release on the website seems to be 10.0.7, where in fact your device should have done an ota update to 10.0.9 out of the box. You also can't install Beta 2 that's listed on the site as it's older than 10.0.9
As suggested, Oxygen Updater is the best way to see what updates are actually available and the global firmware is the only one that seems to be updated regularly atm.
It's not an official OnePlus tool but the firmware is referenced and downloaded from OnePlus servers.

Not corrrect..... I have an EU version and OB 4 is available through official updates so no need to convertt to Global at all.

Not on my official webpage !! Open beta 2 is the only option.

The Beta was available for a short time for EU and Global, and then it was pulled for both and put back up but not for EU (according to my Oxygen Updater)
https://www.xda-developers.com/onep...14-4-ambient-display-clocks-may-2020-patches/ (See update #1)
I just double checked and even through Oxygen Updater (with Advanced Mode turned on), device set to OnePlus 7T (EU), Open Beta (Full), Only Oxygen OS Open Beta 2 is available (I'm currently back on 10.0.9 EU as I didn't want to be on Global not knowing what the differences are)
Moral of the story is though that there's either inconsistencies across devices, or you received the update before it was pulled, or OnePlus are just utterly useless at update cycles... I believe the latter lol.

Haha I love that end analysis ? yeah checked the updater app and experienced the same. I'm okay with the version im on so can wait until they release a beta officially on the UK support pages to try. Again thanks for the responses along with all others that took time to reply. Appreciate it.

Question Is MIUI 12.5 enhanced worth it?

I am currently using Mi 11X (aliothin) running on Pixel Experience. The rom is pretty smooth, but is still a bit buggy at places and lacks stock features like the camera, dolby, memc etc. Recently, Xiaomi has been rolling out the 12.5 enhanced edition globally for alioth devices, which supposedly should be very smooth, with great battery life. Can you comment on this based on your experience?

Can you give me a link to that enhanced edition? I have been using Xiaomi.eu Custom ROM with Root, its ok. I would prefer Vanilla Android, but I need some Stock features, like MIUI Dolby Atmos and the camera-app

I have been trying to install it on my Poco F3. I have watched the YouTube videos by Munchy, but I can't get it to work by update or flashing in twrp. Guess I will have to wait until it rolls out to me.

I read in the changelog of the stable beta 12.5.3 india and global that it is the Enhanced version. I don't flash it because I still have locked bootloader and my region is EEA. However being a beta I don't know if it works well ... I would wait otherwise you can try it in preview on xiaomi.eu.

You can only flash with TWRP or recovery stock. "Mi flash" flashes only fastboot roms and 12.5.3. global is not yet available in fastboot.
But I don't know if the flash of a beta works well.
If you do, let us know how it went.
Good flash ...

If anyone download, does this finally have performance mode toggle inside battery?

The Recovery ZIP you have to flash with TWRP. You can only Mi Flash with Fastboot ROMs, not Recovery ones.

I don't like the answers you've got... It should be possible to flash via miui directly . That's the best way if possible as you will avoid all the potential bugs and slowdowns from the buggy twrps we have....
Open settings , about phone , open updates and tap on the center of the screen on the picture above where it says 12.5 lots of times just like how you open developer options - you have to click like 5-10 times idk....
Afterwards it will say additional options unlocked , click on top right menu , click on choose update package and point it towards the miui download.
It should work...

Nebrassy twrp gives error 7 but vasi twrp gives no error and installs without issues - flash reboot to bootloader , boot twrp by cmd and wipe data. Only after all this boot system.
I'll try to install official way asap but for now it looks like it's doing alright.
Performance mode is there - so to answer original question YES. It's more than worth to install enhanced edition. For me it's a must
edit: Might also work regardless of recovery being twrp as it installs while phone is booted up , upon reboot it should replace twrp w stock recovery but idk if there will be any ilent bugs from doing it like that... I prefer flashing clean rom first then flashing anything else afterwards

I imagined that with the traditional method it would not work due to verification, because after this post I read that the beta is intended for those who are part of the beta test program with their account.
I also figured that the stock flash would overwrite the twrp.
I am glad that the rollout of the enhanced version has begun, thanks for your valuable information regarding twrp.
My f3 has less than 48 hours to unlock the bootloader and I can't wait to try new roms. If the fastboot version is released in these two days I try to flash with miflash.

IDK, but after installing the latest OTA update ( 12.5.3.0) Enhanced Version,
1: My device reboots randomly, sometimes boots into fastboot mode.
2: No noticeable change in battery performance.
3: Themes & Icons Packs won't work properly.
4: Cant choose to re-install the same OTA from the update section.
5: Fixed bugs related to Haptics & Launcher.
Overall, No noticeable improvement in end-user experience.

Please note that it is still in beta so there may be some bugs.
Your phone was born with the global?
Did you have any problems installing it?

Watch this video by Munchy:
Enhanced Edition has barely any changes. No performance improvements. You can lowkey call it a scam.

Question Can I upgrade LE2121(IND) to US OxygenOS 12 Beta

Hi,
I have read many people moving regions or installing different regions ROM. I have a 9 pro with latest IND update. I would like to try the Android 12 based OxygenOS 12 US version.
I bought the phone when I visited
India but I live in US.
Is there a step by step guide to do this? If this is too Risky I am happy to switch to OxygenOS 11 US version.
I am a newbie in this space. I will much appreciate if you could pls be elaborate with your response.

Just download Open Beta zip to root of storage, then select it in local update (press three dots on update page)
You don't need unlock or third party tool.
Actually, I think you don't need to use US since bands are not affected by firmware.
Also IN is the best variant, only IN has theme store and update is rolled out sooner than US.

Thank you. What about battery. My battery drains like crazy. All standard apps drain battery on this phone Outlook, Google photos, Whatsapp etc. I go from 100% to 70% in 3 hours and I have battery saver on and all optimizations on.
I was hoping the regional update my clear anything that might be wrong with this phone. Any suggestions 9?

Question How to convert LE2111 OP9 phone to EU ROM?

[Posting here since this forum seem a bit more active than OP9 forum.]
Hi guy. What are the steps I can follow to convert my Indian(LE2111) OP9 with Indian Oxygen OS to EU variant?
Wanted to get away from the bloatware in Indian ROM & EU variant seems to support dual SIM. Also want the US version of Gpay, etc.
I downloaded Oxygen Updater , changed device to OP9(EU) & downloaded the full OTA ROM. When I try to "Local Install " on Settings page it says "verification failed".
I also downloaded the LocalUpdater apk, which also fails.
I haven't unlocked the bootloader or rooted the device
What steps am I missing?

I have the same needs but for my OnePlus 9 Pro.

Thanks for responding. It's seeming like the process has changed a lot since the last time I flashed ROMs back in OnePlus One days. lol
I'm currently on LE2111(Indian ROM) C60 on Indian variant OP9(dual sim, no wireless charging). I want to move over to EU ROM.
So are the steps:
1. Downgrade to android 11 using MSM Indian tool.
2. Flash android 11 using MSM EU tool
3. Update from OTA/Oxygen Updater.

Or you could do it in simpler way: after downgrading to A11 with MSM Indian tool use Oxygen Updater and select EU device, in the app’s settings: “Stable (full)” update method and enable advanced mode.
This will let you download the latest EU full ZIP, which you can install via the system’s built-in “local install” feature or the separate local upgrade APK https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk
