[Galaxy Tab S Q&A, Help & Troubleshooting] pezley:
So I have been testing a whole bunch of custom roms / Kernals on the Tab S 10.5 ( Wifi ) About now I have tried all the ones from here ( AOSP, AICP etc ) and no matter which I try the performance isn't as good as the stock Samsung ones. This confuses me ? They are bloated with Samsung junk, older builds and generally should be rubbish but here we are and performance simply isn't as good. Whilst the Antutu scores are higher the CM builds for instance simply aren't as fluid, pauses, stutters etc. As minor as they sometimes are annoyingly aren't there ( as much ) on the Samsung roms

In the end I stuck with the stock rom, debloated as much as I could and installed the Google Launcher from the market. It's a shame as I would love a stock experience but it's simply not as usable.

So, are we missing drivers etc ? There must be something in the stock roms which utilizes the CPU/GPU better. Any ideas ?
[Galaxy Tab S Q&A, Help & Troubleshooting] LoVeRice:
Those aosp/cm roms aint official at all, everything is just a port.

Hello

I just got Huawei P8 and it is quite bricked..

Seller said that has been flashed wrong kernel..

Now fastboot bootloader says phone is unlocked but it is not so I cannot flash anything..

There is no any ROM nor recovery installed..

Phone boots to logo then restarts and boots to rescue mode ..

There is still posible to bot in fastboot but cant do anything as cmd says "not allowed"

Huawei provides kernel file which has over 150MB and file is in "tar" so same as samsungs files..

Do you think guys I could fix this huawei p8 phone with odin ?

Thnx

No, odin is only for Samsung devices. Try running cmd ad admin and then running fastboot oem unlock or fastboot oem-unlock.

Now we just have to wait to see how long it takes for T-mobile to put it through testing. I can't wait to have SD card integration with the onboard memory!
[T-Mobile LG G3] hodgestl:
Yep. I noticed this yesterday when I was seeing what is new about 20g. FWIW, 20g is just a Stagefright fix. It will sure be curious to see how long it takes LG / TMO to get Marshmallow out for our G3s. I bet its well into 2016!!!

[T-Mobile LG G3] centipedes:
No you won't. You can get it the same way you always get it if you want to go back to stock. Wait until there are firmware posts and flash them, or wait until the ROM devs have dissected the MM stock and made a customized stock or ripped what they needed out (Data, Bluetooth, GPS, etc).

I believe I read somewhere that you can walk into a T-Mobile store and they can push the update to your phone manually. It's just the OTA isn't ready for release.

This thread says that what was posted on the LG's open source page is only the Kernel and not a complete package. Whether or not that's true is TBD, but that would make sense because if it was the whole thing and it's been up for a week now without a ROM floating around that would be surprising...

[G2 Q&A, Help & Troubleshooting] tharealmb:
Hi all....

I have been trying everything in my power to fix this issue...

The issue is that no matter which rom i try, my device just soft reboots serveral times a day. Sometimes even more then 10 reboots/hour. There does not seem to be any logic behind the reboots.... Sometimes when i'm typing, but also when opening an app... or when it is just in my pocket (you can feel the phone heating up after the reboot is started).

It's annoying the hell out of me.

i tried (all clean, wipe all and/or factory reset):

Cloudy G2 3.3

Blisspop

CM12.1 (unofficial, for F320L)

Am i missing something here? i tried freezing some apps.... but now my phone is stuck on the boot screen (in the background it still works as a phone, but i can't do anything). So before installing (yet againg) a new rom, i'd like to know if there is anything else i can do. I loves Blisspop and CM12.1 but if it keeps rebooting i can't use the phone.

[Verizon LG G4] billybob275:
I finally got it to work with my rooted G4, but I had to rely on Xposed and Rootcloak.

1. Set DPI to the default (640). Unfortunately, Android Pay won't work on anything other than stock DPI. (I went back to stock DPI, but use the App Settings (xposed) app to set my individual apps back to 540) Reboot.

2. Open RootCloak (xposed), and add both Google Pay Services and Android Pay to the block list.

3. Open SuperSu and go to settings. Uncheck "Enable SuperSu". This will take a minute or so to run, but it is reversible (you won't lose root).

4. Clear data for Google Play Services and Android Pay. You will have to set up some of your account info again, and let it re-sync.

5. Open Android Pay and add all your cards. This must be done before re-enabling root.

6. When complete, go back to SuperSu, and re-enable root. Reboot.

These are the steps that worked for me, but YMMV.

I was able to get it working with the exact same steps except I skipped #4 and things turned out fine.
