Hello,

Maybe this is a stupid question: why do you install a new recovery (twrp) if there is not any stable ROM yet?

Kind regards.
[Galaxy Tab 3 7.0 Android Development] Unjustified Dev:
Because it looks cool and a new recovery was needed for lollipop test builds to flash.
[Galaxy Tab 3 7.0 Android Development] bubba_66:
Also seems more stable than the previous version.
[Galaxy Tab 3 7.0 Android Development] Minto107:
And its always a good start... I have big hopes that you will get CM11 soon ;)

Hello, is there any update with this ROM?

The Tab 2 is supported officially by CM, is it possible to include the Tab 3?

where do i find the thread to install this new twrp for smt210r kind need to know how to install it so if someone on the cm 11 for smt210r form could send me a link on how to install the new twrp thanks
[Galaxy Tab 3 7.0 Android Development] Jaykingis20:
never mind i just found a zip file version but i do have a question about the rom cm 11 who ever is still working on it what is the main problem with this rom i know somebody said it was a marvel thing that it could't be found i might can help with this rom when but i will be busy this weekend and next week it probably be the week after i am running a clean install of windows 10 just tell me what all i need to do to help get this rom going so we can get android cm 12 witch would be lollipop tell me ahead time what software to get and i will get busy from there
[Galaxy Tab 3 7.0 Android Development] santabanta114:
There are many guides for ROM building and there is no software to build ROM.

YOU NEED

1) a Linux distribution (eg UBUNTU)

2) sync build sources (should be more than 22 GB)

3) then start build

Happy Building :)
[Galaxy Tab 3 7.0 Android Development] bubba_66:
You simply download the zip and flash through your existing TWRP recovery.
[Galaxy Tab 3 7.0 Android Development] Jaykingis20:
alright just flashed the zip through the older version of twrp and now like the new twrp looks cleaner and smoother
[Galaxy Tab 3 7.0 Android Development] tharmor:
IS there any hope ? Or no one is working on CM11 now ?

wasn't there some prominent problems like WIFI not connecting after it's disconnected till rebooted and screen doesn't turn off and volume 2 step?
[Galaxy Tab 3 7.0 Android Development] jimbomodder:
Yup and many more

Sent from my GT-I9505
[Galaxy Tab 3 7.0 Android Development] santabanta114:
Apparently the WiFi problem of not turning back on is not affecting me all the time. It works normally 90% time and the screen is also turning off normally after a while.

The WiFi signal is weak but even in no signal(when it turns grey) the connection is working.

The screen on rotation flickers sometimes.
[Galaxy Tab 3 7.0 Android Development] jimbomodder:
Yup. Put my tab next to router and barely any signal.
[Galaxy Tab 3 7.0 Android Development] santabanta114:
Yup.. Gonna try to use this ROM for a while since WiFi is turning back on fine for me.. The sound is a complete two step though.

BTW: was using your ROM before :thumbup:

Hi guys i tried to find the kernel for cm 11 from laufersteppenwolf in this thread but i couldnt find. Someone can post it pls thx

[Galaxy Tab 3 7.0 Android Development] popliuc:
He didn't developed a kernel for cm11 because cm11 isn't stable and the development stopped
[Galaxy Tab 3 7.0 Android Development] DarkFrenzy:
[MENTION=3034891]gr8nole[/MENTION]

hi sir! do you know which files are responsible for touch.

i have ported CM11 to T217S , only one big problem thats the touch, touch is not working if i try to touch an icon it will touch other icon or a place. (i hope u get it)
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Seriously where are the devs. Cyanogen is a os built by consumers for consumers. The predecessor of aour tab has reached CM12 but why can't the successor. The build is close to the stable mark. The kernel is near to completion. The libs just need a little adjustmen. Contact me if you are ready to start the project again. I mean a new kernel has been released. Why don't we try this again?
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
The tab 2 is supported because the devs are continuosly working with the device whenever new versions of cyanogen is available. Cyanogen INC does not buid the rom. They only release source codes for developers to work on. If the rom ever gets completed then it will be peblished to cyanogen's repository to make it officially supported. Also updates like new cm versions will be released via ota.

[Galaxy Tab 3 7.0 Android Development] jlazkano:
Thanks,

Are you using this thread ROM?

Is it working well?

Regards.
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
If you will use the rom alone these are thee bugs

1. Screen does not turn off all the way (it glows)

2. Slow ui (at firts but it sped up over time)

3. Wifi signal indicator

4. If you turn off wifi you can't turn it back on. You need to reboot the device.

6. Volume can't be lowered

7. No camera

8. Mic does not work.

I dont know if using the kernel will fix the problems....i'm gonna try tonight
[Galaxy Tab 3 7.0 Android Development] ballerd:
yes I use this rom and to my Knowledge it fixes none of the above apart from slow ui but it makes such a difference I mean huge you will be more than happy anyway and the other issues you mentioned are rom issues as its not stable yet if anyone helps and makes rom stable then all above issues will be resolved :)
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Can you help me out. I know how to fix these problems.......only problem is i Don't have the right software for compiling and such.
[Galaxy Tab 3 7.0 Android Development] ballerd:
Sure tell me what you need
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
I just need you to compile my patches in the audio,camera,wifi,display,ect libs. I'll tell you when I'me done editing
[Galaxy Tab 3 7.0 Android Development] ballerd:
Just saying wouldn't it be better to ask [MENTION=3034891]gr8nole[/MENTION] if he would include your patches he be the best man to ask because if your patches work am sure he would be more than happy to
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
I'm gonna try to contact him. Thanks. I almost forgot that they built this rom. Hopefully he's still up to it. I'm gonna download the device tree now. But the first patch is to include the werewolf kernel as default instead of the cm one. It works way better
[Galaxy Tab 3 7.0 Android Development] jlazkano:
Hello, if you need some help I can try to compile it.

Regards.
[Galaxy Tab 3 7.0 Android Development] ballerd:
No worries am sure he will have no issue aslong as you ask him right and I would also message [MENTION=4716493]laufersteppenwolf[/MENTION] just to ask if he don't mind I can't see him saying no it means a lot and am more than sure he will help you if you have any questions :)

---------- Post added at 07:25 AM ---------- Previous post was at 07:13 AM ----------

Ask [MENTION=6045511]jacobpayag[/MENTION] to message you when he's done editing and I suppose any contribution and help is good if you succeed post finished zip on this thread that way people can test
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Downloaded device tree. It should take me more or less 2 days to finish editing

BTW: I'm still at school. And its a 30-minute bus ride home

Wait until monday. Just give me some time

Update1: [MENTION=5990760]ballerd[/MENTION] the kernel does not work with cm11. The device gets stuck in the Samsung Galaxy Tab 3 logo

Update2: Starting edits on the libs

Update 3: No problem with the device tree though I found 1 file to be suspicious. I'm gonna check the kernel next. It looks like the problem is coming from the kernel. Not the rom
[Galaxy Tab 3 7.0 Android Development] laufersteppenwolf:
If you use the cm branch it should work just fine ;)
[Galaxy Tab 3 7.0 Android Development] jlazkano:
I have a PC with SSD disk.

If you tell me the steps I could compile for you.

I can't run Ubuntu on the tab 3. Does any body know how to. So that way I can work even if i'm in school
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Update: I'm gonna try to build cm10 first. In theory the kernel should work perfectly and moving to higher cm versions shouldn't be too much of a problem. Now just one thing: who's gonna help me?

Update2: I'm desperately trying to run ubuntu so I can work. Does anybody know how?

Update3: I've found a way to run ubuntu using virtual box. Yay. I'm gonna start my own build tomorrow. Hopefully things will work out fine

Update4: Development paused

Reasons

1. Ubuntu does not want to cooperate

2. I need to focus on studiying

3. My schedule is getting a tad bit too tight

4. I need to concentrate on other things

5. Development is only a side line hobby. I usually do these things on my free time.

Note: Don't worry. I'm not giving up on the tab 3. Just give me some time. Thanks to those who will wait

[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Update5: Development for the rom still paused. I'm working on getting Ubuntu to run via virtual box. I'm gonna try my chances with ubuntu 14.XX. pls pray that things will work out with ubuntu 14. And if not I'll try with ubuntu 13 and so on.

WE SHALL KEEP THE DEVELOPMENT ALIVE.

BTW: I recommend switching to other stable roms until I can work out the bugs
[Galaxy Tab 3 7.0 Android Development] RubyUltima:
If you would like help with your Ubuntu environment, I can definitely help with that. Especially if it means getting something other than Touchwiz to this poor device.
[Galaxy Tab 3 7.0 Android Development] Minto107:
You can't run ubuntu on tab3 because this crap is ARM device. To boot ubuntu you need proper architecture/CPU like x86/Intel i5/i7/Atom
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Update6: Sorry guys. Our exams are up for the next week. My goal for this week is to get Ubuntu running properly. Hopefully I can fix the kernel without having to rebuild the entire ROM. I've given up trying ubuntu on the tablet. I haven't tried Ubuntu 14.04 in virtual box but it should and must work. I;'m trying my best. But to those wjo have any distro of linux please try to decompile the kernel and ramdisk, compress it to a zip and send it to me so i can edit the values on windows and try to compile it again.
[Galaxy Tab 3 7.0 Android Development] jlazkano:
Where could I download the kernel?

I use Linux and could help you.

Thanks a lot. I cannot run Ubuntu on virtual box. I forgot to copy the error that I keep getting. I'll send the screenshot tommorow. Anyway, I'll start working on the kernel

---------- Post added at 12:28 AM ---------- Previous post was at 12:20 AM ----------

Update7: Development resumed. Thanks a lot to [MENTION=4358872]jlazkano[/MENTION] for decompiling the boot.img. Anyway Ubuntu still does not want to cooperate or my hardware is just not right. I'll send the error screenshots in virtual box tomorrow
[Galaxy Tab 3 7.0 Android Development] jlazkano:
Hello,

If you want I could install Ubuntu in virtualbox and send you the virtual machine.

Wich version do you want?

[Galaxy Tab 3 7.0 Android Development] jacobpayag:
14.04 will do......keep in mind that I only have 1FGB of ram and an Intel Core i2 formerly known as Core 2 Duo. But thanks a lot man. I'll pm my email so you can send it
[Galaxy Tab 3 7.0 Android Development] Minto107:
I had same problem with Ubuntu like you. I figured out that hardware acceleration wasn't working but I haven't found a fix for that. I just used my older PC where everything worked correctly, but you've got a very nice CPU(popular, capable, powerful) when I have cheap AMD64 Athlon 4600 processor and Ubuntu doesn't like AMD so much but it liked my Intel Pentium T4200

Well OTG can be plausible, working on cyanogen. I don't have a proper distro of linux as of now.

[Galaxy Tab 3 7.0 Android Development] dom2319:
My ROM making skills aren't that good yet, but when it comes to Linux, I know my stuff. So I'll gladly help you :)

Question: why are using Ubuntu? Have you tried Debian or if you want to be more on the bleeding edge try SolydXK.

Both are "rolling releases" (as opposed to a fixed release like Ubuntu or Mint) which means you only have to install once and forever update. Whereas with fixed releases every time another release comes out, you have to re-install.

As for trying a Linux distro, forget USB sticks or Unebootin. Use DriveDroid instead. It's brilliant, you just have to copy on device SDCard, the distro ISO that you wanna test or run (and you can have multiple distros at the same time) and DriveDroid takes care of making it bootable, and then just connect your phone/tablet to your computer with USB cable to boot the Linux distro of your choice.

Don't hesitate to ask if need any help/guidance

[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Thanks a lot. But first i need to port multiple drivers for the GPU, Mic, and wifi. And the reason why I am using ubuntu cause i'm much more famillar with it.
[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Okay. So I found out what's causing errors.

Mic: Driver problems

Slow UI: GPU problems

ART: Apps are not configured to run in ART

Camera: Drivers

Screen Problem: Either Driver, GPU, or Value problems

2 Step volume: Values not set properly

WiFi: Driver or vendor problems.

Some of these may be true some may not. And I'm gonna need a lot of help. Calling out to [MENTION=3034891]gr8nole[/MENTION]. Pls let me help you or can you help me. As this is your project after all.
[Galaxy Tab 3 7.0 Android Development] gr8nole:
I have absolutely zero interest in this project now. I put in way too many hours working on this device and it is way too frustrating trying to get this Marvel junk to work.

Good luck!!
[Galaxy Tab 3 7.0 Android Development] vorpalblade77:
GPU has upstream driver now (etnaviv). Wifi/bluetooth has upstream drivers.

Mic and camera do not (as far as I know) have upstream drivers. I've been working on getting kernel updated to linux 3.4.67 (for ease of porting). Right now I'm stuck at 3.4.11 (there are some sdcard changes there).

See https://gitlab.com/sm-t210r/android_kernel_samsung_lt02 and https://gitlab.com/sm-t210r/android_device_samsung_lt02wifi.

The first is the kernel source I'm working on and the second is my (personal) device tree, with a file giving driver information (first entry into the kernel, not where it is working for the specific silicon in the SM-T210R).
[Galaxy Tab 3 7.0 Android Development] nysascape:
Can someone help me? I installed this and stupidly enabled ART, but it worked fine. After rebooting after rebooting to ART, the screen has been f**ked. It flickers between the colours normally and it like shakes. I'm on 4.1.2, the orginal firmware, kernel, recovery and stuff is all there. I don't know what happened, but if I take a screenshot and look at it on my PC it looks OK, and when I boot it up & go into download mode, the colours and screen are fine. I don't know if this is related; like the screen stopped working after I rebooted on ART. Thanks in advance. I'm gonna go post this on Q&A as well.

Is there just a driver missing from this rom that wont let the camera work? i love it except that there is no camera but im trying to learn this so i can add things to this project
[Galaxy Tab 3 7.0 Android Development] Gamer_DooD:
Can you please fix the volume its really unusable? This is a cool project for tab 3! Please guys! And YouTube has no 720p option...
[Galaxy Tab 3 7.0 Android Development] ndg_2000:
Look at developers comment above !!!!!!!!
[Galaxy Tab 3 7.0 Android Development] Minto107:
And this is why TAB 3 will never get a working CM. There are no required files and drivers
[Galaxy Tab 3 7.0 Android Development] jlazkano:
Is there any similar device with same hardware?

Could we use code from other devices?

Which drivers are missing?

Kind regards.
[Galaxy Tab 3 7.0 Android Development] Minto107:
I remember that someone was talking about some HP Stream 7 tablet which has exactly same hardware but better software (smoother and lighter). Drivers meh mostly all are missing. Probably hw acceleration is not working, gpu, screen, screen, camera, speakers. Lots of things[emoji14]
[Galaxy Tab 3 7.0 Android Development] vorpalblade77:
Yes and no -- as stated above by Minto107, there are other devices which use the same soc like the Samsung Galaxy S III mini Value Edition or HP Slate 7. See also specout SOC and specout Slate 7.

As far as drivers in the linux mainline kernel and firmware in linux-firmware:

What is missing:

Touchscreen (BT532 for mine)

cameras

microphone

possibly speakers

Some battery stuff

Probably GPS -- haven't checked

Backlight control (BACKLIGHT_TPS61165 in board file, BACKLIGHT_PWM might work)

IR (remote)

That said, I haven't looked at the camera, microphone, or speakers yet. I'm mostly trying to get a booting kernel first (I just got some stuff for UART in yesterday, still need to find a store with resistors though).

Drivers that exist (bold are pretty much required):

ETNAVIV (needs modification for compilation, may not work currently) for GC1000

Either stock driver or re-implementation (etnaviv-mesa, mesa when mainlined)

PJ4B (CPU subtype)

MWIFIEX (wifi)

Firmware: sd8787_uapsta.bin

BT_MRVL_SDIO (bluetooth)

Firmware: Same as MWIFIEX (sd8787_uapsta.bin)

BMC150_ACCEL (for accelerometer, I need to check this though)

GP2AP020A00F (light sensor, pretty certain this is the right one)

USB_SWITCH_FSA9480 (multifunction USB port, can do UART) <--- Really important to have this working if there isn't an easy way to use JTAG

RTC_DRV_SA1100

Either CONFIG_CHARGER_BQ2415X or nonexistent (CHARCHER_ISL9226)

MMC_SDHCI_PXAV3 -- may have some issues (brittle when merging in newer code from android-3.4 common)

For the android-4.4 kernel, I think that only ETNAVIV needs to be added to the missing list. I've also had issues when I've modified the storage device subsystem -- I don't know what is going on there yet.

And I haven't figured out where the JTAG ports are yet -- I think I know where it is, but I'm not certain. Most of the JTAG ports I've seen have metal spikes coming out for attaching a debugger (and I might need to kill a transistor somewhere as well).

[Galaxy Tab 3 7.0 Android Development] jacobpayag:
Apparently, I am confused. Now the screen completely turns off as long as there are no open apps in the background. So the problem might be in the handler. As for the mic, libs for the dual mic set-up are missing. Most likely adding them should fix the mics. Can somebody try that out
