Thank you very much. Now we can have pure and simple cm12.1 in our T805 devices. Thanks a lot. Does it work with LTE data?

[Galaxy Tab S General] Nexorrr:
Yes. I tested LTE and it works
[Galaxy Tab S General] calj17:
Ok thank you Nexorrr. Will test it out. Thanks for your support friend. I love CM12.1 that has no extra stuff. Only pure android. Thanks so much. Will be following your cm12.1 updtates

Hello!

Thank you very much for the new build!

Unfortunately, phone is still broken. I could make 2 phone calls, but not able to close the calls. At the 3rd try, couldn't make the call at all.

Beside of that, data works perfectly.

Hope one day we will have a non-touchwizz rom with phone working :)
[Galaxy Tab S General] Nexorrr:
Big thanks for testing. For now I'm thinking how to debug phone problem
[Galaxy Tab S General] calj17:
For me works great too. Data works and rom is very fast. Phone calls broken. Thanks Nexorrr

So I have two news: good and bad.

Good new that I know how to see phone errors now

"adb logcat -b radio" shows errors with our RIL customization

E/RILC ( 2384): Send Response to RIL_SOCKET_1
W/RILJ ( 5095): [6754]< GET_CURRENT_CALLS exception, possible invalid RIL response

So swiching RIL to lt033g not solving phone problems and we need other fixes.

Bad new that I need to write handler of modem commands for our device.

Hello,

Thank you for new build.

So, just tried, unfortunately, phone is still buggy for me.

- First try: no sound / voice (in both directions)

- Second try: phone rebooted

Anyway, thank you for all your efforts!
[Galaxy Tab S General] Nexorrr:
Thanx for testing.

It is strange, I will check it again. Voice defenetly worked.

What modem version installed?
[Galaxy Tab S General] anarianthe:
Uuuh... T805XXU1BOD2 ?
[Galaxy Tab S General] Nexorrr:
It seems equals to mine.

So may be something wrong with build... I'll recheck it
[Galaxy Tab S General] Nexorrr:
Intresting... I have same bugs on dirty install

But if I do wipe before install it's much better. Can you try this too?

Looks like some settings stored and interfere
[Galaxy Tab S General] Natex2:

Voice working, but sometimes I have reboots on outcoming calls.

Don't no exactly why for now
[Galaxy Tab S General] anarianthe:
Just tried and...

Wow! Now it works!

I will try a few days and report, but phone seems to work fine (did triy 3-4 calls, no bug, no reboot). Thank you very much and congrats, this is really nice to finally have a non-touchwiz rom with working data and phone!

:good:

RIL(for phone calls) is changed only, so we need to test this part for stability
[Galaxy Tab S General] calj17:
Will test it. Please tell me why bootanimation is so slow and laggy in the rom? I do also get some slow downs during screen transitions and game play

Enviado de meu SM-N910C usando Tapatalk
[Galaxy Tab S General] Nexorrr:
I haven't this problem and never had... May be you changed cpu governor? Check this problem on clean install (wipe all cache and system too)
[Galaxy Tab S General] Nexorrr:
If no more testers, I'm in fixing operator search for now.

But it's have strange operators response from modem:

0 = "Beeline"
1 = "Beeline"
2 = "25099"
3 = "available"
4 = "26466"
5 = "25011"

13 = "UNKNOWN"
14 = "6604"
15 = "TELE2"
16 = "25020"

22 = "forbidden"
23 = "UNKNOWN"
24 = "MOTIV"
25 = "MOTIV"
26 = "25035"
27 = "forbidden"

Have no idea how to parse it. It should be separated every 6 strings for each operator (each portion must have at least: operator name + code + status), but it is like a garbage

I can confirm the slow boot animation. The same problem was found in early builds of CM 12.1 for my S5. Not anymore, though. :confused:

Please confirm if slow boot animation after all wipes and clean install

P.S. Although I don't mark this problem as critical if starting time is normal
[Galaxy Tab S General] gordp:
Thank-you, Nexxor - it seems to be working for me (I have no SIM, and therefore cannot comment on phone/data).

For other Forum members and the later Googlers:

I am using TWRP 2.8.7.0 intended for 'chagallwifi'. This version of TWRP seems to work fine on our 'chagalllte' Tab S too, but it won't allow flashing of a conflicting .zip image :( There is no harm in trying to flash the 'lte' version while running the 'wifi' recovery - try it for yourself and notice the fail-message. Here is how I deal with this:

I use 7-Zip (on my Linux system, but Windows or other should be fine too). I extract Nexxor's .zip file to a new directory of the same name. Then, I navigate to \META-INF\com\google\android\ and edit the file updater-script to change just one word near the beginning of the updater-script file:

From:

assert(getprop("ro.product.device") == "chagalllte" || getprop("ro.build.product") == "chagalllte" || abort("This package is for device: chagalllte; this device is " + getprop("ro.product.device") + "."););​

To:

assert(getprop("ro.product.device") == "chagalllte" || getprop("ro.build.product") == "chagallwifi" || abort("This package is for device: chagalllte; this device is " + getprop("ro.product.device") + "."););​

That's enough to keep TWRP happy :)

Use 7-Zip to re-zip Nexxor's work with this slight change, copy over to your device, and flash away!

HTH,
[Galaxy Tab S General] Nexorrr:
Or you can just flash this twrp ;)

I have the SM-T805 I can test it, once I find out how to download the ROM. I am using it with giffgaff/O2 in the UK. Except I am not sure where the download links are. Are they on the OP? If yes this post has broken links and multiple references, not very clear what is what.

[Galaxy Tab S General] Zilliman:
OK got it.

I need some help re-installing TWRP. I had installed the wifi version twrp-2.8.7.0-chagallwifi.img.tar, but today I tried to install the TWRP mentioned in a post above for the LTE. However I cannot get the tablet to start into TWRP. The process of flashing TWRP has always been touch and go for me because I must be missing some important step.

What I currently do is:

1) press vol down + menu + power to go into download mode

2) run Odin

3) select AP and the TWRP file

4) press start

5) tablet reboots and gets stuck on the "Samsung Glaxy Tab S Power By Android" logo.

6) Press vol down + menu + power to switch it off

No matter what I do, I cannot get TWRP to start - any ideas please?
[Galaxy Tab S General] Nexorrr:
I have done it long time ago by this description with no problems.

[Galaxy Tab S General] Zilliman:
I did not see how to install TWRP. Basically my tablet stays on the "Samsung Glaxy Tab S Power By Android" logo. I cannot switch it off. The only key combinations it recognises is Vol down + menu + power, for 8 seconds it reboots back into the logo (hangs?) and for 10 seconds it boots into the downloader. I would like step for step instructions of how to install TWRP because it seems the first time I did it a few days ago it was random.

---------- Post added at 01:32 PM ---------- Previous post was at 01:23 PM ----------

I have now used Odin to flash the stock ROM and this resets fine and puts the tablet back to original spec. At least I have got the tablet back, in "just out of the box" mode, and my backups are in ... TWRP... Damn.

I am 100% certain that we need step-by-step instructions of how to install TWRP. It is not simple!

The official TWRP website does give a clue that there are issues, but the explanation is at best fuzzy! I wonder who writes their instructions! https://twrp.me/devices/samsunggalaxytabs105.html

If someone really knows how to install TWRP please let me know.
[Galaxy Tab S General] Zilliman:
OK I have installed the CM ROM now.

Bug #1: Settings/Users/ it says "You (Owner)" and when I click on it it says "user does not exist". Not sure how this happened. From setup it should know my name from Google.
[Galaxy Tab S General] Nexorrr:
It is issue for cm12.1 developers :)
[Galaxy Tab S General] Zilliman:
Bug #2: If you select very low DPI screen scaling (which I do not understand how this works however small DPI means small fonts, compressed screen like desktop), so if you choose the lowest DPI, the desktop is only half populated leaving large bands of unused areas left and right. Applications run full screen fine, but not the desktop.

Is there a place to report these bugs?
[Galaxy Tab S General] Melington:
Confused

Hello,

i tryed to install your CM12.1 unofficial, but i can not do it :(

i have cm12.1 from post 223 and the twrp from post 221

i can find the .zip file in twrp but when i install it it says: "Zip signature verification failed: 1"

i dont know what to do, pls help

best regards

Edit: Nevermind me :D i fixed it. Just had to reload the Rom and tada it works

Edit2: everything is fine and working on my Tab S but i have a question. do i need to root it again? and if so, how?
[Galaxy Tab S General] NewT64:
Hey there,

I just generate an account here only to thank you Nexorrr and all the others for the latest nice rom.

[Galaxy Tab S General] Jithu_Vijayakumar:
I flashed the new build (cm-12.1-20151010-UNOFFICIAL-chagalllte) 2 days ago (Full wipe and fresh install)

Boot animation is slow

Android.keyboard stopped working (Same problem happened with AICP's latest build)

Uninstalled android keyboard n using google keyboard as of now

Call functionality is inconsistent,Initially it was crashing on outgoing calls now it seems to be working fine

In coming calls are fine

Prior to installing this rom i had AICP's rom which had so many issues with calling

This rom is better...

One main problem is the top portion of the screen is getting overheated while playing games,i mean excessive heat...

Another thing is capacitive buttons always blink when the tab goes to sleep mode,irrespective of whether there is notifications or no notifications (Same thing happened with AICP's rom)

Don't know why the buttons blink,Is there a way to turn it off.
[Galaxy Tab S General] Zilliman:
When I tried moving icons on the desktop I got the notification "Unfortunately Trebuchet has stopped" and this kept happening all the time.
[Galaxy Tab S General] Melington:
Feedback

Hello,

after testing for a while, i have to report some bugs.

#1 : Phonecalls: recieving a call works but quality is very bad

#2 : Bootscreen is very laggy and seems to be very long (at least 30-35 secs)

#3 : Trebuchet is crashing very often

#4 : Overall performance seems very good and stable

will test a little bit mor and write a detailed Testprofile in a few days

best regards
[Galaxy Tab S General] Nexorrr:
Ok... too many feedback about slow animation - I'll try to fix it
[Galaxy Tab S General] Nexorrr:

[Galaxy Tab S General] NeWONEx:
For now everything work very well ! Thanks man you did great work [emoji108]
[Galaxy Tab S General] Nexorrr:
md5 sum not needed but recomended. It is very small and used by recovery to check ROM-file for download errors
[Galaxy Tab S General] Zilliman:
As a hint, I use TWRP to switch between stock ROM and CM12. It takes some time to do wipe clean-restore-reboot but at least I do not lose my stable stock ROM and I can get back to it quickly. I store a number of backups on the external SD card.

This is a question for Nexorrr: do you have any knowledge on how RAM and maybe SWAP is organised and used? I am 99.99% convinced that the 3GB RAM is a joke and forces the OS to keep unloading applications resulting in the browsers unloading their tabs and making browsing the internet painfully slow. Is there a way to use RAMfrom the SD-card to boost the internal RAM? I have already setup a SWAP partition on the SD card but am not sure if it even cares.
[Galaxy Tab S General] Nexorrr:
Swap not used and not recomended, because 3Gb of RAM is enouth for all.

We have only a little slow CPU for our big screen resolution.

SD card is the slowest memory in device, so do use it only for store files.

You can use ads blocks for browser, because it's interactive and use a lot of memory
[Galaxy Tab S General] Zilliman:
I use two browsers. Chrome because it is the most reliable, works correctly with everything I have tried. I also use the Adblock browser for Android, to avoid ads on sites that usually have a lot of ads.

I am not sure where you base your statement that 3GB is plenty. I have two browsers open with 4-5 tabs. The slowness is evident in repainting tabs, reloading tabs, everything.

If I load another application it will instatly cause my browsers to unload their tabs. We are not even talking about opening Office files, like Excel and Word documents or anything like that.

Maybe I should take a video and link it here what happens when I click on a tab - how it spends many seconds repainting the tab, or worse, how it downloads the tab over the internet once again. Or maybe my tablet is broken even though it scores really well on Antutu.
[Galaxy Tab S General] Nexorrr:
In any case it is not device specific problem so I can't help. Sorry.

But you can check memory usage by application to be ensure about free memory. I have at least 1.5 Gb (or even more) for applications and it should be enouth for 4-5 tabs
[Galaxy Tab S General] Zilliman:
Thank you for the explanation.

If I understand it right, we boot the device, run nothing except the browser, open 5 tabs we are OK. Now open another browser, open another 5 tabs, and now we not OK anymore.

Are you saying that is is known and acceptable performance?
[Galaxy Tab S General] Nexorrr:
After boot I have 1.7Gb free memory

I opened 10 tabs with dirfferent sites and after that have 1.4 Gb free memory. Swithing between tabs without reload.

Check your installed applications
[Galaxy Tab S General] suviralu:
What twrp version are you using as it won't work for me

I have TWRP v2.8.7.0 on my chagallte. I just wiped all (data, system and cache) and now I cannot install because the TWRP says my device is chagallwifi and the image is for chagalllte. But there's no TWRP for chagalllte AFAIK. So coming here to get some hints as of some working TWRP version, please.

Install feedback - BT headset NOK, volume adjustement not working

Well, finally! I now got rid of the Samsung ROM on my SM-T805!

I'm glad it works very well, however I have to main concerns with it:

- it won't pair with my BT wireless headset (Powerbeats2); seems that it cannot pair because of a PIN problem, but the headset cannot display prompts ;) The LG Watcth paired correctly

- the volume control do not affect the headset output, where the sound is all way up to the maximum

- the sound quality during the GSM calls is not very good, digital signal artefacts could be heard

These call connectivity problems should be fixed. Please let me know how to help to fix them as they should definitely fixed, as both BT and classical signal paths have problems.

Minor problems:

- Soft buttons periodically flash when in standby

Continuing to customize it and enjoying this very responsive and beautiful ROM.

:)

---------- Post added at 08:00 PM ---------- Previous post was at 07:12 PM ----------

LTE is not working neither!

EDIT: LTE & 3G is working after entering the right operator APN parameters. My operator has several APNs and they depend on the area.
[Galaxy Tab S General] Nexorrr:
1. About bad voice quality. It seems need to enable noise suppression (it not so easy because of vendor components)

2. BT.. I don't know - have no BT devices

3. Volume control... may be audio paths need to be reconfigured. But not sure

4. Buttons periodically flashes: looks like buttons not disabled in suspend mode

Who is ready to fix all this bugs? :)

Fails to install

Hey, hey!

Using TWRP to install fails with a message regarding the fialure of an executable in the zip file. Any ideas?

Couldn't do an md5-check because the page loads a blank for me.

The ROM I downloaded is cm-12.1-20151015-UNOFFICIAL-chagalllte.zip, md5= 953612315bad4dc88f7efe6dede8d46b, on the slowest possible connection you can imagine, remeniscent of the 56k dial-up days; a painful 7-hour download.

This 805 is now my only computer, so I need to gain the freedom of access to it that I've become accustomed to in the Linux world for the past 20 years. I just need a very light, functional OS, with as little GUI and Google as possible, into which I can install and run a chrooted linux distro and all the apps I'm used to.

Thanks to you guys for putting the time in and sharing your work with the world; where would we all be without the doers and givers?
[Galaxy Tab S General] Nexorrr:

[Galaxy Tab S General] ubun2boy:
Thanks for the link. That version of TWRP (2.8.5.0) gave me the same error as the 2.8.7.0. regarding the updater binary in the zip. I see that this has been an issue for a number of people when installing a CM11 OS for the same model, though I wasn't able to find the solution. In addition, it was unable to mount the extSdCard, no matter what I tried. It was okay once I re-installed the later version of TWRP, though.

No problem! I'll keep sniffing around till I find something that works.

Thanks for the input!
