B506 Results

I'd installed and tested the build B506 (Unicom) with Android KK 4.4.2 for Huawei Ascend P6-U06 Int. Ver. Everything went smooth and Smartphone worked perfectly. For Google Apps (Contact Sync, Maps, Play Store..) this can be downloaded from the Chinese market (Huawei App Center), just type Google and install the requested apps from the first package that appears. Only the latest CN version of the Vroot is working for Root. IN CASE THAT YOU'LL INSTALL THE "ROOT BROWSER", DO NOT INSTALL THE TOOLS AND REQUESTED FEATURES (BUSYBOX, SQL DRIVER...) THIS WILL MAKE YOU LOOSE THE ROOT ACCESS FOR THE APPS, and the only that I'd found to get it again was to reinstall the firmware, and apply the Root again. Be careful in case of installing apps that needs to install extra features to work through root. BusyBox Free worked with no problem.
The rollback to B132 and B125 failed through the hard reset (using the stock recovery)*.
Only users from South Africa reported problems with Internet Access, Costa Rica networks should no have this problem (I didn't had it with Claro). HSPA+ not available.
Battery life is more stable than B125 and B132.
Secure & tested root apps:
-Android Tweaker 2
-BusyBox
-Go task Manager
-GPS Essentials
-SetCPU
-Faster GPS
-Avast Anti-Theft
-ES File Explorer (Replace Root Browser): For root file exploring and editing New!
-BusyBox Installer By JRummy Apps Inc. (Replace Busybox by Stephen (Stericson) because of better perfomance and do not affect root access) New!
-CPU tuner (Rooted phones): Better performance than Set CPU New!
*Report if is possible to rollback to B125 or B132

As I remember reading, there is a way to revert to JB. It's in a thread about the b506 firmware. I'm on my phone now and can't search for it. Will post the link when I have some PC access.
Speed isn't what kills you.. the sudden stop does! Oh, and stupidity..

I don't have any issues with network access on Vodacom, South Africa. I think it might be network specific then? I've reinstalled the firmware so many times, and I've never had issues with my data.
Just so everyone knows that it's not the whole of South Africa with issues [emoji4]

I have a problem with my reception. If invoking the handset from Standby the first thing it does is releasing the network connection. After a few seconds it comes back. Had this behavior also with the B132, only B125 was working normally for me. By the way I am located in Germany and using T-Mobile/MobilcomDebitel.

I see. I haven't noticed that happening with my device, but I'll check if it happens when I'm out, because I have really bad signal at home.

Try adding "ro.config.hspap_hsdpa_open=1" (without quotes) on the build.prop file, it worked for me. Need root access. The file is located on "/system". This build use GSM only if there's no 3g or + networks. (only 2G/GSM configuration available on configuration menu).

Ok i did it and it work's!
Thx

If you try, you will brick your phone, C00 is CDMA phone and B506 is for WCDMA phones P6-U06. They have different hardware.

My data works perfectly, and I have my apn settings as well.
Maybe you should try editing your build.prop file, to allow hsdpa, as said in one of the posts above.

21-1-2015 [MT01-U06] Ascend Mate B321 Android 4.4 KitKat Official Firmware

Ascend Mate is officially 2 years old now. Even though it packs similar hardware as the Ascend P6, Ascend Mate always got less attention when it comes to firmware updates. Ascend P6 got the Android 4.4 KitKat update few months ago but Ascend Mate was stuck in Android 4.2 with EMUI 2.0 until now. The last recorded firmware update for the Mate was announced in September last year http://huaweinews.com/2014/09/ascend-mate-b930-firmware/ and now Huawei has a whole new firmware update ready for the Ascend Mate in Chinese region numbered as B321.
Even though the numbering scheme implies that B321 is possibly a downgrade compared to previous B930 firmware, its wrong. B321 packs Android 4.4 KitKat and Huawei’s latest Emotion UI 3.0 interface. Unfortunately as we mentioned earlier, B321 firmware is intended for the Chinese region but you can install it on your international Ascend Mate with minimum hassle. B321 is marked as a development firmware and its the very first Android 4.4 firmware for the Ascend Mate so you should expect to have few issues here and there.
Changelog doesn’t mention any new special additions to the features but all the new features of Emotion UI 3.0 are carried over to the B321 firmware. Mainly the UI is completely overhauled thanks to EMUI 3.0 and few EMUI 3.0 specific apps are added. Here are the details of this firmware in an easy to understand form,
Model – Ascend Mate MT01-U06
Firmware version – B321
Android version – 4.4
EMUI version – 3.0
Stage – Development
Region – China
Google Apps included – No
Languages – English,Chinese,..
Size – 842MB
On official changelog, Huawei has mentioned that you should only upgrade to B321 from B930 in order to make sure that your device doesn’t get bricked. Upgrading from other versions other than B930 might be possible but we strongly recommend you to follow Huawei’s instructions and upgrade from B930.
If you happen to install this firmware on your Ascend Mate, please share your thoughts and issues you faced in the comments below.

I just flashed the rom and it runs pretty smoothly! I flashed B930 as recommended before flashing this B321. I've played with it for about an hour and everything seems to be working fine! The only little 'annoyance' I can see is the DPI seems to be set differently to B903. I'll try and tweak that later. I'll also be trying to flash GAPPS shortly.
I took some screenshots which show the apps the phone comes with and a few apps running. Click Here!
EDIT: Ok, too get root on this rom you need to install TWRP recovery and flash this. eRoot and Root Genius both didn't work. Still trying to get GAPPS to play nice.
EDIT 2: Hmm.. Root Checker is saying I don't have root :/
EDIT 3: Still can't root to work. I've given up for now but I'll try again sometime later this week.

Where are u from...? Is the data connection working..?
Sent from my HUAWEI MT1-U06 using XDA Free mobile app

tried this rom but it has d same old issue....NO DATA CONNCTION in INDIA....ithot its the official update from huawei & they must have corrected the issue...
EDIT : - Data connection working after resetting APN settings

I am going back to B907. While the rom looks nice, it just gets slower and slower throughout the day. It also doesn't save any photos for me, which is quite annoying. Likewise it will not send MMS, even after I put the MMS APN in manually. I will be keeping an eye on future updates to this
EDIT: So, I can't downgrade for some reason...

Hello,
Installed from the B930 with the stock recovery.
No problem.
All my implementation remained.
No more flickering of the screen.
No NFC
wifi 802.1xEAP without SIM option (for french users FreeMobile)
Root realized via TWRP recovery (during the first use of recovery)

Thanks

Somethings to note about this rom:
It won't let you downgrade after it has been installed. I've tried flashing other recoveries such as the B906 recovery, but it won't downgrade. TWRP works, but you cannot flash Huawei "Update.app", meaning you can only flash roms like Cyanogran, Pacman, etc.
You need to apply your APN details manually in order to get MMS and Internet to work. Even after apply APN details however, I still couldn't get MMS to work.
Calls sometimes only appear for two-four seconds before disappearing. This lead to a lot of missed calls.
There appears to be a battery drain on this rom, as my battery life was lower than when I ran it on B907. I didn't take any screenshots unfortunately.
I found that I could only have one app running at a time. When I tried to switch back into another app the app would reload completely. This was quite annoying as it meant I couldn't upload any photos to Twitter as when it loaded up gallery it reloaded Chrome, canceling the upload. This could be because my model only has 1GB of RAM.
This reloading also affected the home screen, as it would reload most times you hit the home button, and therefore took a while to load home. You also cannot set your own launcher.
I couldn't figure out how to root it. I tried multiple programs and tried flashing root through TWRP but no dice.
GAPPs wouldn't flash either, so I had to download the Google Play apk from the web.
The resolution is huge, probably because of the DPI setting, which cannot be changed because no root.
If you want to run KitKat, I think this rom is much better. It can be flashed through TWRP and you can also flash GAPPs and Root through it. The DPI is also fixed. However, the battery drain and reloading of apps and homescreen is still present.
For now I would just stick with non-kitkat roms.

EMUI 11 [Global] Huawei P30 (ELE)

Huawei has finally begun the rollout of EMUI 11 for the Huawei P30 (ELE) and P30 Pro (VOG) today. The version is 11.0.0.138 and the package size is about 1.81 GB.
How to check for the update:
1. go to Settings then System & updates, then open Software update, select Check for updates
2. open the Support app, go to the Service tab on the bottom bar, tap on the update, then select Check for updates and then download and install
3. connect to a PC with a USB cable and check for updates in HiSuite
Feel free to share your experience with EMUI 11, please also share the exact type of your device (e.g. ELE-L29 C431E27R2P5) and how did you manage to update to EMUI 11, also mention from which build did you update.
In case the download method or updating with HiSuite proxy will be available, also share a how-to and I kindly ask you to perform a SafetyNet test.

I used VPN and chose China, then set the region of my phone to Nepal yesterday. The Support app found 10.1.0.201 with this trick. Then today, about an hour ago I checked the Support app again and it finally offered me to update to EMUI 11. Hooray!

They didn't, that was my point. It's only newer devices that are without Google services.

I just got my P30 (ELE-L29 UK Unlocked) updated to EMUI11, updated to the January security update, then enabled my VPN with china selected then checked for updated in the support app.
Also a sidenote, this is EMUI11 but it's still android 10, and good gesture navigation is still not working with Nova launcher
Edit: Now fails safetynet, so no google pay for now....

How come that your phone failed the safetynet test if you updated via OTA? I'm on 11.0.0.138(C431E8R2P3) and it passes the test and Google Pay works fine.
I believe that gesture navigation will not work perfectly if you use a third-party launcher. I use Evie launcher and I also had to install MyGesture app from Play Store. I like it better than the stock gestures, more customizable.

I have no idea, I did a backup with hisuite, factory reset with recovery mode and now it passess, so it might have been a bug or one-off or something ¯\_(ツ)_/¯

got update today, UK Vodafone, ele-l09 /c431e8r3p3/

Yesterday my phone received the EMUI 11 update (build 11.0.0.138), no need to do any trick. Model ELE-L29, unlocked, Spain.
Since the upgrade, VoLTE was enabled (it was off before the update) and the option to disable VoLTE is no longer available on the settings menu.
Anyone with the same issue? Any way to disable VoLTE using call codes or something else?

Stll nothing here. Getting frustrated because the website for my phone company shows the update as being released.

Hello, I have the conversion from T-Mobil to Global version. I can't tell you about GPay, but in my case about the device, the build number is unknown, and in its photo it shows a One Plus 6T ... This happened in all A11 betas. I don't know if the same will happen to you.

Play store says my device is certified. I already had cards on Google Pay and they are still there and the app isn't telling me anything is wrong so I assume that is good as well. I assume if all was good on the previous version, it should all still be fine.

Everything works fine for me. I don't have any lag. The only time I ever see lag is every now and then when swipe typing on Google keyboard. Other than that, the only issue I see is the unknown build number. I was never on the betas. I went from stable 10 to stable 11.

Yes same. Make sure you've Disabled Magisk modules before attempting and backing up data

Is there not a fastboot GLOBAL rom version available for 11.0.0.2-OnePlus7TOxygen_14.O.26_OTA?

I am currently on India 10.0.37 version and rooted with Magisk. Rooting works even though Magisk manager crashes immediately on opening. So I can't update Magisk.
I got OTA update to v11. If I update and can't update Magisk will I just loose root or will the phone go into bootloop?
How do I root Android 11? Is TWRP now working?

Question Help needed to return to Android 12 stable

I opted in for the beta of A13 with my Vivo X80 Pro (Europe version).
The battery drain gets worse every week.
Now I found out that to downgrade to the stable version, I need to send the phone to VSP Data.
That is on the other side of Europe for me.
So, I want to downgrade it myself.
How to do this? Because all the tutorials I found online are outdated, incorrect or incomplete.
At the moment PD2185BF_EA_A_13.1.11.7.W30 is installed.
I did a lot of custom ROM with the HTC HD2, Samsung S3 and Xioami's before. But cant get this simple downgrade to go
Who can guide me with a complete tutorial and working drivers (for Windows 11 Enterprise)?

If you have the Mediatek version, you may have some luck experimenting with mtkclient. We do such downgrades on 1+ Nord2 without bootloader unlock, so it might be possible to do something similar here as well.
If you don't think you have the chops to figure it all out, wait till somebody with your device does though.

The EU version (W30) is the Snapdragon variant.

Welp, if the official instructions don't work for you (people have mixed success with it), you're indeed hosed and you'll have to send it in.

I suggest going to the service center if there is one in your country. They can downgrade it there.
Or just wait until stable or more capable beta versus on of A13 is up.

Sorry if someone already mentioned this but have you tried the Vivo downgrader computer application? It's the only thing that let me downgrade. I do have the Chinese version though so I am not sure if it only works on that.

This looks to be a Chinese program.
I'm afraid it will brick my phone since my ROM is EU and not Chinese.

I opted in for the beta of A13 with my Vivo X80 Pro (Europe version).
The battery drain gets worse every week.
Now I found out that to downgrade to the stable version, I need to send the phone to VSP Data.
That is on the other side of Europe for me.
So, I want to downgrade it myself.
How to do this? Because all the tutorials I found online are outdated, incorrect or incomplete.

Does Vivo not have service in your country? I also tried donwgrade, but unfortunately I didn't find any working tools, ROMs, or procedure....
I have the same FW version as you and I have no battery problem. Check your apps. Often some update with gplay fails and then there is excessive consumption.

How about this?

They did, that is why I bought the phone.
But after 2 months they stopped.
Never a Vivo phone for me ever again.

And the 'local upgrade' function on the phone worked. (for the first time of all the tries).
But after the restart, it said the upgrade failed because the installed version is newer.
