Thank you for your hard work. I believe it was the first enabler for all those who were waiting for a usable ROM for this device. However I think you know that your work is a fork of other on going development tree that is better aligned with official CM rules that will eventually lead to the official release, you state that yourself in this thread 's first message.

Thanks again for your impressive work!
[Samsung Galaxy Alpha] yassine78:
you make a brillant work, continue supporting our device. you're the man
[Samsung Galaxy Alpha] dineshlives:
I hav g850y what to do
[Samsung Galaxy Alpha] MisterEcks:
Unbelievable

It seems that the only capable ROM developer for this device has chosen to cease development because some self appointed arbiter of the rules has decided his work is not original and simply moves this ROM in a fit of megalomania.

Now we are left with 5.1.1 ROMs that don't work or ports of older versions.

Well done mods.

Kyasu... Please come back... Or at least tell us where we can go to continue to support your excellent work on the slte!
[Samsung Galaxy Alpha] modpunk:
Feel free to contribute to my tree. We would get things faster done. I'm working together with i9500 and treltexx developers as our devices are partly similar. The more people collaborating the better CM will be in the end.
[Samsung Galaxy Alpha] surfin-bobby:
I will switch to you ROM in the next days, your progress on BT Carkit looks very promising!
[Samsung Galaxy Alpha] modpunk:
I got bluetooth headsets working, carkit mostly work but needs more cleanup. However the issue right now is that bluetooth mics are not working. Everything looks correct here ...
[Samsung Galaxy Alpha] maciocho:
Hi all,

This is a lovely ROM but unfortunately it does not connect as a phone over Bluetooth - streaming only. Is there any option for someone to have a look at this please?

Thanks,

[Samsung Galaxy Alpha] MisterEcks:
Hi All,

Sadly Kyasu looks like he has left and is not coming back. It seems unlikely that anyone is picking up this particular rom and so I think it would be better to close this thread officially so that people know it is no longer under development.

System-UI has stopped when playing music

My Alpha say's "System-UI has stopped." everytime I start playing music! I tried using different music players(Spotify, Play Musik, CM Music), but everytime the same effect.

After clicking ok it restarts the System-UI and the Error-Message comes again. Any suggestions? :confused: :eek:

i am using the CM 12.1-2016218-UNOFFICIAL-slte with Xposed, Root and apps like Greenify, Amplify and the Lollipop MobileRadioFix as Xposed Modules.

I attached my logcat while plaing music with screen on, and the Problem occurred, so it should be in there.

Looking forward to your ideas ;)
[Samsung Galaxy Alpha] MySelf_v1:
Hi there everybody. I have a big problem:

Samsung G850F ( Italy ) i have no signal.

Last ROM installed was the stock one. This is the first ROM i flash. Anyone knows why?

[EDIT] While ROOTing, i've formatted everything and i had to push the ROM with adb in the phone because it was not booting anymore. May i have formatted the modem? or something?

REPORTING BACK - Breaking News - ive installed epsilon rom than this one and now it FULLY WORKING :) ( on epsilon WiFi was not working :)) ) i will report back for daily use issue
[Samsung Galaxy Alpha] MySelf_v1:
+1 Audio streaming with TimMusic at max volume sounds horrible.

There are no major issues with phone calls between my family devices (g850f and stock xperia) in my country (japan).

Is echo terrible or minor issue?

Does anyone else have echo problem?
[Samsung Galaxy Alpha] philneo2:
yes i have little echo with your rom my carrier is orange "france" and i lost signal sometimes

[Samsung Galaxy Alpha] Gh3ttoKiLL4:
Didn't test older versions of yours (only [MENTION=242033]bonuzzz[/MENTION] 's one a few month ago @ http://www.android-hilfe.de.

Until now nothing new except new CM sources.

RIL/Audio quality is ok, didn't test HD-Voice until now. Edit if tested.

My voice on Whatsapp is still too quiet.

First boot was soooo freaking fast! Don't know if this depends on the zero slimgapps or nah.

EDIT: Forgot to mention that there was a error while flashing via TWRP 2.8.1.1 (didn't remember which). But rom works fine at all.

What about call quality ?

Envoyé de mon SM-G850F en utilisant Tapatalk
[Samsung Galaxy Alpha] Blubberor:
Just check my comment right before your question.

Audio means call quality.
[Samsung Galaxy Alpha] sphazer:
Call quality is almost perfect.waiting for video recording quality to be better,then for me its almost a complete daily driver. Kudos to the dev.;)
[Samsung Galaxy Alpha] vectro73:
Huge problem for me - mic does not work for outgoing calls, for incoming calls quality is perfect.

Upd: full wipe solved the problem

Upd2: not solved. Problem is on "ok google" detection. Help please.

Upd3: yep, it is full bug here:

1) Turn on Ok Google From Any Screen

2) Make outgoing call

Mic won't work during this call. No way to enable it. It will work on incoming call though.

Workaround for now: turn off Ok Google From Any Screen

Tested on all kind of GAPPS: TK, PA, CM-gapps, some other random GAPPS packages from micro to stock.

BUGS

-When you touch button to change camera, the app closes. This bug is on every app that uses the camera.

-(Apps) When you try to listen a voice note WhatsApp with front speaker (call speaker), the sound keep on silence, so, you can't listen with that speaker.

And rest is all okay, very good job!

New version is up.

I rewrote the audio HAL based on the manta (nexus 10)'s one.

Phone call over bluetooth starts working.

Outgoing call over BT works but incoming call over BT does not work well with my environment.

And I cannot reproduce call quality issue such as echo, so I cannot debug it.
[Samsung Galaxy Alpha] vectro73:
"OK Google" from any screen still blocks mic for outgoing call. Can U please debug this problem?
[Samsung Galaxy Alpha] kyasu:
I cannot reproduce your bugs.

incoming call screen appears as pull down; system recognizes the Google master account; no lag closing recent apps; no FC on alarm.

Thanks.
[Samsung Galaxy Alpha] kyasu:
Sorry, I don't understand your problem. Please describe in detail, step by step. Thanks.
[Samsung Galaxy Alpha] vectro73:
1. Enable OK Google from any screen feature.

2. Make a outgoing call.

Another person won't hear u during this call.

But for incoming calls all work well.

3. Disable OK Google from any screen - all calls wokr well.

As others said before, problem is on opposite phone, not gf-850.

I can confirm that problem is still here, when You are calling/receiving call NOT YOU, other side hears echo of its voice. so i guess gf-850 sends voice with this "echo"

regards,

m_p11
[Samsung Galaxy Alpha] kyasu:
I confirmed the bug. I will check it.
[Samsung Galaxy Alpha] kyasu:
Humm.

Please test the attached slte-call-singlemic.zip.

Voice call uses both builtin mic and back mic. By flashing this singlemic mod by TWRP, voice call uses builtin mic only. This mod may not effect on "echo".

You can back to two mics by flashing flashing slte-call-original.zip.

[Samsung Galaxy Alpha] vectro73:
"OK Google From Any Screen" does not block mic in outgoing calls now. Fixed.

People are complying they can hear themselves while I'm calling them. Even when earspeaker has very low volume. I guess something is wrong with top mic here, like, it is using for communication audio instead of noise reduction. I had not so much time to test it properly. Maybe somebody can confirm/reject this issue.

[Samsung Galaxy Alpha] Blubberor:
From my end no problem at all. Neither via bt nor via phone...and i did a lot of calls.
[Samsung Galaxy Alpha] vectro73:
OK, for those who wanna test echo problem, here is instruction how to do it:

What U need to do before testing:

1) U need second phone, not G850F

2) U have to set earspeaker in-call volume to max.

Test:

1) Take G850F and make outgoing call to second phone. Call must work via earspeaker, not speakerphone!

2) Leave G850F in other room.

3) Speak in second phone. If U hear your own voice - this is our bug.

4) Make incoming call to G850F. Call must work via earspeaker.

5) Leave G850F in other room again.

6) Speak in second phone. If U hear your own voice - this is our bug.

Repeat it with those ZIPS on other page of this thread. When u test it with ZIPs, make sure "OK google from any screen" is disabled.

This is my bug list for CM:

echo voice during calls

incoming calls: The device needs too much time to turn on the screen.

audio recording: too quiet (voice)

video recording: wrong colours (stock camera app)

Vibration strength is very low at certain times.

cm-12.1-20150724-UNOFFICIAL-slte.zip

Disable a call noise suppression by default. This may be effective on a call echo issue.

For me, there is no call echo issue on both sides.
[Samsung Galaxy Alpha] sphazer:
I just cant see how you dont have any problems with calls

Help recovering from an incomplete installation

I've just tried to flash the image. apparently it was done successfully but afterwards it doesn't boot (it stays in the initial screen "samsung galaxy alpha --- powered by android" forever).

I can still go to the bootloader download mode and enter the TWRP recovery.

Considering that I was running stock (rooted) Samsung 4.4 ROM, I may have missed the "Make sure that your G850F uses the lollipop bootloader and modem." requirement :(

Do you know how I can get into a compliant mode from the stage I'm in now? Hopefully without having to (re)install the Samsung ROM...

TIA,

Nuno
[Samsung Galaxy Alpha] Ashareth:
You get the Samsung Lollipop 5.02 Rom, you flash it with Odin, root (with CF autoroot) it, install TWRP and flash CM again.

It'll be far quicker than fighting with it for hours or waiting for it, and it was stated quite often that flashing LP-based custom Rom requires the Lollipop bootloader (wich is obtained by flashing the official LP rom for most people, other ways being tricky as Hell).
[Samsung Galaxy Alpha] sunsettrack4:
You have to flash the official Lollipop firmware provided by Samsung. Otherwise, your device won't be able to boot into CM12.1.
[Samsung Galaxy Alpha] gabrielking9:
Do I need to root to install TWRP?

Isn't more easy to include bootloader in the ROM or Recovery? I remember when I was using another galaxy I could easily go from android 2.3.4 to 4.0
[Samsung Galaxy Alpha] nuno.f.ferreira:
Thanks. I don't use Windows. Do you have an informative link for Linux users?
[Samsung Galaxy Alpha] vgran:
If I root my Alpha, do you recommend Kingroot or CF-Auto-Root?

And what is the different CyanogenMod and ResurrectionRemix?
[Samsung Galaxy Alpha] nuno.f.ferreira:
By the lack of answers it seems I have to get my hands on a Windows machine, ok I guess I can do that.

I have one last (I hope) obstacle though.

I'm planning to follow instructions (sorry, can't post links because I'm new to the forum) that demand USB debugging enabled but I don't have it, is there a way to enable it from the bootloader or the TWRP recovery?

---------- Post added at 08:35 AM ---------- Previous post was at 07:52 AM ----------

Another question: I have OTG cable and can access/copy file from TWRP. Can I install stock or other firmware in that way to get out of this situation?

Basically the 2 links you need on linux to do the same (Heimdall is a crossplateform community driven alternative to Odin).

The rest is basically the same than with Odin to flash a Rom, juste replace Odin with Heimdall. ;)

This guide might be useful (the links are for a 4.4.x version of Android, but it's the same for Lollipop, except you need the latest 5.0.x CF autoroot version from CF's website, and you get the TWRP version, flashable with Flashify or RASHFR from this thread : http://xdaforums.com/showpost.php?p=60668850&postcount=27).

Should be able to get everything you need from those.
[Samsung Galaxy Alpha] Blubberor:
Which pit file did you use? In general I am running mac OS, only for flashing i use windows...

Good that heimdall works in your hands as suggested ;)

as far as as I read now you donÄt need a PIT for flashing - then not recognizing the phone on the new Macbook over USB-C to USB adapter might be the problem.

thank you anyway for the good thread. this one I did not find via google and search function.
