I believe magisk won't do this anymore, and Chainfire sold SuperSU to a Chinese company years ago! (Good on him!)... Magisk is now the defacto root solution, and it's open source to boot!...

Do yourself a favour, cleanup SuperSU, ditch 4.4.4 and install this 7.1 c/o @fwiep w/ adopted storage working out of the box (just be sure to update baseband as I mentioned):

[Android Q&A, Help & Troubleshooting] pndwal:
Did you confirm you have 3.1.1?... How are you installing the twrp?... Are you first extracting the .img file, then flashing that to recovery partition as .img? PW
[Android Q&A, Help & Troubleshooting] Blank tape:
I thought fwiep fixed that but as I never tested that or subsequent versions I can't confirm the fix works. Finally, taking a looking at the most recent zip and the fix itself it does something different to what I suggested so I'm guessing not. Sorry to provide such late feedback Frans!

Anyway, I worked around the problem with a setprop command in adb shell:

setprop ro.product.device Y550-L02

This must be done before an install is attempted. It seems values are cached.

FWIW, I used twrp-3.3.0-1-y550 back then.
[Android Q&A, Help & Troubleshooting] Blank tape:
To pose a question myself: Is there a way I can use to return the phone back to B240 stock. B247 changed the boot process in such a way that while flashing TWRP in fastboot appears to work it does not replace the stock recovery.

Unofficial TWRP 3.1.1.0, Dec. 16 2017 by desalesouche ===> Post

That is the correct TWRP file above; it is a zip file, not img.

Did you confirm you have 3.1.1?... How are you installing the twrp?

I installed the above TWRP 3.1.1.0 using the zip file install method in my current installed TWRP on my phone so via TWRP.

Are you first extracting the .img file, then flashing that to recovery partition as .img?

Where do I extract the img file from?

My assumption is to extract the recovery image file from your latest custom ROM, and then flash it to either my boot or recovery partion on my phone using my current installed TWRP on my phone. Is this correct.

Then flash your latest custom ROM.
[Android Q&A, Help & Troubleshooting] pndwal:
No, it's only uploaded as a zip... Extract the img file and use that. 🙃

Does the splash screen confirm you now have 3.1.1_0?

Via current twrp yes, as zip no ... Change flash type to.img and flash extracted.img file...

From the zip archive...

Does it include recovery?

Correct method via TWRP is flash recovery.img to recovery partition generally for our device, never to boot partition...

Can flash ROM or recovery first... Order doesn't matter afaik.

Guys, many many thanks for all your input these last few weeks and days.

Without your help, I would never ever been able to transform this old phone into what it is today.

This may depend on xloader version of both (can't roll back to earlier) as seems Huawei started implementing anti-rollback with this device... I read reports of several issues for B249...

But are you sure recovery isn't just being replaced on system boot (also common practice)? ... Usually booting immediately to twrp after initial installation allows twrp to install it's fix for this, or simply installing magisk... Still, it could be a bootloader thing as similar issues are reported for B249... PW

For me personally, I like / need to have a number of Google apps incl. Chrome browser, Webview, Maps etc, Play Store access to apps / updates, Safety net API (in Google play services) working for bank app, etc etc...

Moreover, Android w/ proprietary Google apps may be fine for a TV box or an automobile interface, but as Google's mobile OS a Smartphone is pretty much crippled (or dumbed down at least) w/o their proprietary offerings in my view...

Xprivacy issue for Y550

Hi all,

First of all thanks for all who work to root this phone, all is under control :highfive:

(Huawei doesn't send me any code, so I used this way to have it : http://en.club.vmall.com/forum.php?mod=viewthread&tid=30795 with model : Y550-L01).

I just want to share my experiment with xprivacy.

Xprivacy isn't compatible with xposed 2.5.1 (last framework working with EMUI).

And I can't found any older version working with it.

So, I finaly install the last xposed framework (2.6.1) and desactive into option "hook ressource".

Good new is that newest xprivacy work !!! :good:

Bad new is that some "modification" modules shouldn't work but I don't know which. :confused:

Android Recent App Switcher

Hello xda community!

First off I want to thank you all for making this Y550 thread and including all the information one needs for his phone!:good:

Even though [MENTION=4618037]dimspace[/MENTION] explicitly says in his instructions that the SuperSU root manager won't work on stock rom's my thick head doesn;t want to accept this. (Since I run SuperSu on other stock rom's just fine...)

So I experimented around installing the SuperSU 2.46. The root binary of SuperSU works just fine. (Root Check also confirms root access and correct root binary version).

But when an app (like for instance TitaniumBackup) requests for root rights, the SuperSU doesn't prompt you to allow for root rights and the app never gets the root rights (even if you configure SuperSU to allow all requests without prompt) I then proceeded to uninstall SuperSU, but leaving the root binary (which basically grants root access to everything, which is quite dangerous) and then all app had root rights. That means that the SuperSU root binary actually works, but the app managing the root right requests has a problem, which I cannot figure out...

And now to my actual question: When I long press the HOME Button a Google OK search page pops up, which is for me very annoying since I am used to the default recent app switcher of Android. (I come from Android ICS)

I googled quite a while trying to figure out how to change this setting without success.

The only thing I could find is that the AOSP has a special setting under "settings->Buttons" where you can configure what long pressing the HOME Button calls. But we don't have this setting on our Y550...:(

Does anyone of you now how to configure this setting?

Cheers..

[Android Q&A, Help & Troubleshooting] JDKKF:
To answer my own question....

After quite some research (quite amazing how I didn't notice it before) I know that the long-press actions of the HOME and MENU buttons have been swapped. (in comparison to Android ICS)

It just shows how I really hate new changes to stuff I am used too. (I live by the standard of "never touch a running system")

Now I am looking for a way to revert this functions back to the way that I am used too. (I am quite stubborn, right:p)

Well, if I find a way, I will post my solution...
[Android Q&A, Help & Troubleshooting] hecaex:
I think Huawei hided the possibility somewhere in their files of EMUI, but without root I think there won't be away to swap the button functionality back to what you were used to.

[Android Q&A, Help & Troubleshooting] JDKKF:
Re-mapping key button actions

Hello again, so here are the two ways I found to remap the KEY Buttons actions.

The first is for everyday Users(Xposed FrameWork) and the second is for hardcore modders (hacking the system .jar files)

EASY SOLUTION

Install the XPOSED FrameWork that is compatible with our Device (2.5.1 according to [MENTION=6457573]therealvdeadline[/MENTION]) and install the XPOSED ADDITIONS Module.

When you enable the Module in the XPOSED FrameWork and reboot the phone, you can remapp single press and long press actions of all buttons. You can do so much more, like configure the delay of the long press:good:

With the PRO version of the Module you can do the actions application specific!!!

HARD SOLUTIONS

This method is basically only for experienced modders. Note that I did not try this method and thous cannot guarranty that this method works. I just include it for the sake of completion.

To remap single press actions you could simply modify the "/system/usr/keylayout/Generic.kl" file. There are lot of useful tutorials here in XDA that do basic key-layout remappings in this file (even though the file structure is self-explanatory)

Remapping the long-press actions is ALOT more difficult. The long-press actions are hard-coded in the system-framework. (Presumably in the "android.policy.jar" system-framework file)

Basically you have to edit the "PhoneWindowManager.smali" file found in "android.policy.jar". Normal procedure would be to Deodex the "android.policy.jar" then extract and edit. But since this is a basic system-framework file you would have to Deodex the whole ROM (really error prone), because all the other .odex files are based on basic system-framework files like "android.policy.jar". And after the edit you probably want to Odex the whole ROM again (which is even more difficult than Deodex) to profit from the Performance Boost of Odex ROM's.

Even though this sounds like a real good intro-to-modding-Project, I did not do it. Reason is the do-not-brick-new-phone-before-6-months-have-passed Period is not yet over.;)

Finally I want to recommend the awesome XPOSED FrameWork Modules suggested by [MENTION=6457573]therealvdeadline[/MENTION] in post #393 (I cannot post links...)
