Wanted to leave some feedback.

I actually have been using your latest CM12.1 and have been experiencing battery drain. It even loses battery when standing by. A few percent every 15 minutes or so, which is not normal.

CM12.1 V5 has very good battery life but has missing button settings, which is bothersome.

Hi

I've installed cm-12.1-20160902-UNOFFICIAL-y550, tried to install link2sd but sd is not found. Tried reformat, partinionning, change sd card and impossible to have it recognized.

Hi, still not much stable for me. Optimizing apps caused 6 reboots, initial setup 2, then it was stable in standby but alarm sound didn't work and when I've tried to launch an app the system crashed again.
[Android Q&A, Help & Troubleshooting] Sparkrite:
Don't know the difference for sure, but my experience so far with 246 is that it is slightly less stable than 239. Little things like losing the pics for contacts, which a reboot will revive and also it will not keep "swype&dragon" as my default keyboard after a reboot. Certainly no discernible speed increase.

I did not notice either of these faults with 239 and so for these reasons I am thinking of going back to the former build.
[Android Q&A, Help & Troubleshooting] Sparkrite:
I know that to flash the system.img within fastboot it is with the command:-

Fastboot flash system system.img

Is the command to flash say the boot.img ?:-

Fastboot flash boot boot.img

And to flash the recovery.img?:-

Fastboot flash recovery recovery.img

I'm in desperate need of the stock rom for my L02. I did a factory reset through Vol Up + Power and now my home button, notifications and power menu fail to function.

I need some help!!!!

Edit: I'll try flashing the L01 System.img to my L02. Will report back.
[Android Q&A, Help & Troubleshooting] lin_ux:
Good luck with that, I hope it goes well.

Please keep us informed on whatever you notice has changed, especially the 3G and 4G bands.

Fingers crossed you can still connect on all frequencies to whoever your carrier is. :fingers-crossed:

Who are you with? Are they using Telstra, Optus or Vodafone frequencies?

I've had one device in the past which suffered with losing access to my required 3G band (it lost Optus 900MHz but could still get Telstra 850MHz) after flashing a rom from a slightly different model, but I've had others devices that were fine.
[Android Q&A, Help & Troubleshooting] therealvdeadline:
I'm with Vodafone, my phone is unlocked though so I'll try another sim as well.

I've got the Update.app downloaded and I'm trying to extract the System.img but Huawei Update Extractor seems to hang during the extraction. I'd post a screenshot but I need to post some more first. In the meantime this will have to do. imgur.com /xhufiTx.png

It has been stuck on that extracting files screen for about a half hour now.

Any ideas?

EDIT: I ended up using a pearl script instead of the program above and it worked! Got the System.img flashing now!

EDIT2: FLASHING THE L01 FIRMWARE TO MY l02 Y550 WORKED!!!

I flashed the L01 firmware onto my L02 and it booted and I have FULL BARS!
[Android Q&A, Help & Troubleshooting] lin_ux:
That would be great, especially anything running on Optus, I mainly use Virgin so the 900MHz on 3G is important, as is connecting to 4G.

Well done! :good:

I bet you feel relieved now :D

Please keep posting anything you find interesting/odd about the L01 firmware compared to how it was out of the box on the L02 version.

PS. I had no doubt that the phone would boot and work after flashing the L01 version, it was just the fear that something might not function correctly afterwards...
[Android Q&A, Help & Troubleshooting] therealvdeadline:
Thanks!

The only differences I've noticed so far is that I now have a "Huawei Cloud+" app and that in the about section it says my phone is the L01 model.

I still have my Vodafone apps and the phone runs smooth as butter on this firmware.

I rooted it again just fine and have xposed working as it should.

Edit: It also came with an app called "Kingsoft Office"
[Android Q&A, Help & Troubleshooting] lin_ux:
That's great news for all us L02 people.

I bet you can't stop grinning :D

That's a pretty decent office suite, I usually install it on my devices.

You can get the latest version of that on the playstore, it's now called WPS Office...

I know it's a hassle, but would you consider writing a short and sweet mini "how to" on how you did it, including links to the files you used.

Hi. Back again :)

Quick question about the rooting process outlined here - its recommended to use Superuser over Supersu - is that a licensing issue or a technical issue? Just curious ...

Is there anything preventing one from uninstalling Superuser and flashing Supersu? I only ask because I noticed a Dev's note warning "latest version of Supersu required" (Interceptor-NG).

How to flash L01 firmware to L02 Y550

How to flash L01 firmware to L02 Y550:

I flashed this System.img through Fastboot which is Volume Down + Power on boot. This will also work for the L01 Y550.

The only differences I've found are that the L01 Rom comes with these two apps, which are absent from the L02 stock firmware:

Huawei Cloud+

Kingsoft Office

Download Update.app. I used this one found in the 2nd post of this thread. Beware, it's BIG! http://android-host.de/HUAWEI/Y550/B239SP01/B239SP01.zip

Extract the System.img from the newly downloaded firmware using the tutorial here: xdaforums.com/showthread.php?t=2315547

Download the Slim Android Sdk from the bottom of this post and extract it to a folder somewhere. http://xdaforums.com/showpost.php?p=57359697&postcount=13

Grab the newly acquired System.img and put it at the root of the Slim Android Sdk folder.

Boot your device into Fastboot mode. To get into Fastboot hold Volume Down + Power on boot. Once there plug your device into your pc.

Shift + Right Click in the Slim Android Sdk folder and click "Open Command Window Here".

Finally, paste or type out this command into the window. This process will take a few minutes. Once done your device will boot!

Fastboot flash system system.img

You're done!

The phone should slowly boot and then show the screen asking for your Country etc.

If you guys have any questions, feel free to ask.

And I'm still a problem.

I've tried all the methods listed here.

Installing the SD card does not go. Fastboot installation goes. However, no matter which system image using fastboot wgram always installed my version B239.

B246 installs and shows that the B239 Uploader.

I did even format the system partition. The phone does not boot the system because it was not. Install from SD card not to go. She walked to install fastboot. Wgrywałem version of the B246. After starting in the settings, I see that the version B239.

[Android Q&A, Help & Troubleshooting] therealvdeadline:
Thanks! I did enjoy writing that up. When I'm allowed to post images I'll edit the tutorial adding some in. There's also a few more things I'd like to add to the tutorial, I wrote it late last night after all.

My Y550-L02 is running without any issues on this firmware. I've got the phone back exactly how I had it previously! :D

On a slightly unrelated note, what urged me to give flashing the L01 firmware a shot was Link2SD.

I installed Link2SD because I was running out of space on the phone. I moved all of my user apps and a large amount of my system apps to a 2nd partition on my sd card. All was well and I had heaps of free space on my phone!

Until I rebooted it.

On reboot Link2SD failed to read my sd card meaning I had an empty home screen. All of my apps and a large amount of system apps were missing. I tried rebooting again to no avail. I tried accessing the sd card on my pc, but as it turns out windows can't read the 2nd partition of sd cards. Meaning I couldn't access the apps from my pc.

I decided to start over, I formatted the sd card and did a factory reset on my phone. I thought that doing so would give me a fresh install but seeing as I had lost a large amount of system apps I was left with the same almost empty homescreen.

My phone wouldn't function correctly, the home button wouldn't work, I had no power menu, no notifications among other things.

As a last resort I decided to flash the L01 firmware to my L02 phone. It worked!

My phone is fine now and everything works as it should.
[Android Q&A, Help & Troubleshooting] lin_ux:
Great, I think you can start adding images etc. after about 10 posts, so you are not far away from that now...

I've had a similar disaster with Link2SD way back in the past, because of this I'll never use it again...

I wrote about this to klaidone who also suffered pain from using Link2SD, you can see my post here:

http://xdaforums.com/showpost.php?p=59027150&postcount=286

That's all that matters. :cool:

Screen overlays problem in CM-13 ROMs

In the past two weeks I tested several CM-12.1/13.0 based ROMs (detailed report to follow), with most of the time spent with NATO66631's ROMs. As most testers confirm, they are superbly fast & stable. As for the AOKP based ROM, it can be installed with minimal GAPPs, flashed in the same run; I have not been able to confirm the boot loop problem reported by some testers.

The most disturbing problem I have encountered has to do (possibly, I am just guessing) not with NATO66631's coding or the AOKP code base, but with MM/CM-13's security model. For no good reason at all, apps like Keep, WhatsApp and Fb Messenger refuse to record audio, take photos, or pick up and send files, claiming a screen overlay problem exists which must be fixed. When you go to settings and disable all screen overlays for all apps (even those like OmniSwitch and SuperSU which cannot function without), nothing happens. The problem persists. Indeed, it disables FB Messenger as a video chat app. You enable all screen overlays, and again nothing happens. Viber is not affected. But other, non-IM apps, are affected: ROMSettingsBackupPro, for instance. So this is not a problem confined to accessing media files and media devices.

We are talking about a serious bug, due no doubt to a hysteric security model. The problem was not present in CM-12.1, let alone in CM-11.

BTW, I see I have also activated in L-Speed an option "assertive display". Don't know what it is, and since L-Speed doen not put its scripts in /etc/init.d for everyone to peruse at ease I cannot check it out easily. Might it be the culprit?

By the way Since MM android needs permisons for each app. So you may need to enable permisons for apps. try that.
[Android Q&A, Help & Troubleshooting] DMaglaras:
No good. To begin with, yes, when you go into settings "app change permissions" (in casu, for WhatsApp), you discover that the app has permissions to do nothing! To change that, system says you need to disable screen overlays first. Back to screen overlays config screen, the pertinent app is not even listed among those drawing screen overlays. And even if you disable ALL screen overlays (which would, BTW, cripple such apps as SuperSU and OmniSwitch), nothing happens. It is a Catch 22 situation. It is not that the idea of per-app-permissions is bad (in fact it is excellent). Rather, there is a screw-up somewhere.
