i9100 CM11 - Galaxy S II Q&A, Help & Troubleshooting

Hi there guys.
Is there anyone working on CM11 for now ? I can't find any info on CM site about i9100 (I believe it should work flawlessly as google wants to support older phones).
Just let me now, please !
Cheers

the guys from the team of CM now versed in the system, because there are many things requiring adaptation. So wait for CM 11 I think is closer to the new year

Here you go.. But it's still in testing stages.. You could test and report to the developer for its development..

You can use OmniRom instead. I used CM 7, 9, and 10, with a Galaxy S1 and then S2. I recently switched to OmniRom because they had a working KitKat rom. Basically a group split off from CM after it became a company, and that group is called OmniRom. CM's i9100 development has all but stopped, but the OmniRom have KitKat rom nightiles that are quite stable. I'm using as my daily driver, and all features work. My phone is faster that it was on CM10.2.

Note: As per the XDA thread, you need SuperSU and GApps. Please use Paranoid Android's GApps modular mini. The full one didn't work for me, and others have said the same.
The only bugs I'm having with OmniRom are:
(1) Automatic time zone (set it manualy)
(2) The OpenDelta over the air updater doesn't work properly yet.

Problems to execute Cm11 on my s2
Hello, I wonder if any Modder or Dev could help me.
I have a Galaxy s2 I9100 stopped there two years, and recently tried to install Cm11 him, and when I start the phone it loads the bootloader Cyanogem Mod, and then a message "Shutting Down Power Off" appears.
I tried using other versions as Slim Know, Paranoid, Pac Rom, etc ... and all the same thing happen. I decided to go back to official samsung 4.1.2 rom, it worked okay, but the phone does not load, an error appears stating that the phone battery with this high temperature, but the phone does not heat up, it is normal temperature coma.
I took the phone in technical assistance, which found that the problem is in the motherboard. I wonder if any Modder or Dev could help me on how to disable it in CM11 rom, or which file responsible for turning off the phone in case of failures. Thanks in advance
(Sorry for my bad english)

Handwriting to text
Hey
I was just wondering if cm11 has a handwriting to text feature.? I can't seem to find it, if it has it.

Update: Been using it for a little under 3 hours, with a mix of Wi-Fi and can confirm that Data works in San Antonio Texas, it's been amazing. After everything settled in and downloaded all my apps, I installed TricksterMod to use the Interactive Governor, it runs very smooth. In addition, will confirm that both SMS & MMS Text messaging works, and Wi-Fi Tethering works. Thank you SO Much LLoir and everyone who is working on this. It really is amazing. I can't say that enough. Okay, just got done trying my Bluetooth headset, audio on games works as for music as well, but alas sadly not for calls, however, I am going to try a wired headset to see if that works.

yes please ALL bugs, please make sure you have the xda 2013 theme on (bottom left corner on the site) so you can see the bug report tab. Also you will be able to see the Q&A section CM10.2 ATT thread, where you can ask questions
all questions should go to that section please
thanks
Data/WiFi working great (no lte here so can't test), messaging too, and whole ROM seems to be running very smoothly. Almost faster than stock I'd say and the phone seems to run at about the same temperature - though not as hot as usual when using a lot of data. Didn't encounter any unmentioned bugs and not had any crashes in my day of use, seems pretty stable. Nice job Lloir, honestly the only thing keeping me from using this is the call/audio issue. You've got an awesome start here, thanks for all the hard work!
guys please use the Q&A section or even the review tab (you need the XDA 2013 theme on)
thanks
Any update on the status? I'm itchy to try this out but would really like phone audio before I do.

[Q] CM 10.2

Hello
I just installed CM 10.2 - alpha 11 on my gt-s7710
And it is the best OS I've had on a phone to date. (my first CM)
it's really nice.
but unfortunately I have the problem with (like manny other) "Mobile network not available"
so I'm forced to go back to the original ROM.
is there anyone who can help or can the impressive developers say anything about when they expect to have a solution to this?
or would it help to install alpha 10 or CM 11?
Hoping for a solution as soon as possible, I'm about to throw up of the samsung android.

Have to get a logcat to be able to give to the developer for troubleshooting as some do have those issues, but most do not, so it's not a universal issue. Are there other modems to install to try for your phone? Sometimes that can help.
adb logcat -b radio > radio.txt
That will give the developer info on what might be going on. Unfortunately you have to get a few more posts in before you can jump on the developer forums, but you gotta do what you gotta do...

Just registerd to say thank you for 5.0 android!
Only yours build is working awesome! NFC, camera, battery life is exelect! I'm very glad. One problem is that i can't put some widgets on desktop... it crashes and reappearing without my widget.
Why you didn't update your thread, and what is differences in your build(for exmpl. the 2th of December and the 9-th)?

I haven't gotten to the point with cm-12.0 where I'm comfortable "advertising" it yet. Once I get it building with linaro, and get init.d scripts and some other goodies working I'll do a new thread. As it stands, it's very much the same as brothaedhung's with some extra kernel kangs and some device tree tweaks.
As far as widgets go, I'm not sure as I haven't seen that issue. Could you describe the issue with some more detail, and get a logcat if possible?
Thanks for the kind words though

Oh, you won't believe I just disable "Don't keep activities" and it works now!!!:laugh:
The problem was when i tried to put Clock for expl. the launcher crashes and appearing again without my widget. Now, i've put my widgets and turn on "Don't keep activities". Perfect! I could not spot any problems, yet!!! Good luck with developing, and thanks again!

02/03/2015 - Sorry guys, I've been slacking off on updating this post. All current builds are using my KK kernel brought up for LP, with stock frequencies instead of low_cpuclocks. I'll be posting a new build later this morning. As far as I know, this is the only CM build still using mako sources

Noticed this over here after looking in the Canadian section (which has most certainly be dead for a while). Great to see you're still active on this. Just want to make sure before trying this that there's nothing else required to move from KK to LP (assuming not since its on a KK kernel still). Any particular recovery recommended and/or version? I'm on a Bell E973 using PAC 4.4.4-RC2, TWRP 2.6.3.1.
Edit: Decided to update recovery to 2.8.4 from brothaedhung after doing some lurking around. Flashed 02/03 and full stock PA gapps. Everything butter so far. Cheers!

I have the same issue in your latest CM12. Proximity and brightness don`t work at all. I use jb e970 modem. Don`t flash hybrid radio because I`m in Russia. Also there isn`t any frequence low than 300 Mhz...
And I try your build of CM11: 20141111. There are a lot of bugs:
1. In profiles doesn`t work ring mode "normal". It doesn`t swith to it after another modes (vibrate and mute).
2. Don`t work "Double tap to sleep"
3. In perfomance dont`t work setting minimal and maximum frequency - after rebooting they are turned to default.

"ap watchdog bark detected"
Help!
Since i flashed 12.1 rom, this message with green screen appears frequently!
5.1.1 CM12.1 Unofficial, Watchdog Kenel Panics (green screens)
long post, so if you want the meat of the story scroll down!
hi guys, i'm an avid user of the e970 and i found this marvelous forum to be one of the most useful resources ever. freegee, lgnpst for when i bricked my phone, cm11, cm12, solid geeb kernel, validus, and now cm12.1 unofficial; it's all there. i'm certainly enjoying the experience that this device paired with this community has to offer.
first i'd like to thank the developers, and i'm seriously appreciating the active development on 12.1. i just finished using validus and while it was a much more solid experience than the short-lived cm12, android 5.0 was still killing me in terms of battery life. 5.1 certainly fixed that up though.
i want to second a few observations that are being made, which are the green-screen happenings. i want to mention something in particular though:
when i first flashed 12.1 unofficial i didn't have the recommended gapps at the time, so i flashed the minimal gapps for 5.0 (just to get wheels rolling per se). sure enough, it was a crazy experience. com.google.<insert service name here> was crashing repeatedly, often causing loss of functionality or green-screens. in a day i'd get anywhere between 4 and 7 green-screens (this was for three days, i'm talking about the 4/21 release). i re-wiped and formatted /system and re-installed 4/21 cm12.1, along with the recommended gapps this time.
NOW i'm having far fewer crashes, far fewer slow-downs and stutters; overall a much more lean experience. i also want to especially thank the developer for one thing: THANK YOU, for giving me back HSPA+ speeds on my att jb radio. validus and cm12 for some reason wouldn't give me HSPA speeds, just slow HSPA speeds that would take forever to peak at 200, 250 K/s (averaging around 70 to 140 K/s). now i can enjoy speeds up to 900 K/s (i'll run a speed test when a more stable release comes out)
so, is it gapps or a kernel issue? newer gapps reduced a lot of problems (though that's a given). also i'd like to point out another error: wi-fi. the mac address keeps changing upon reboot, namely the last three hex values. the first three are always 00:11:22. this wouldn't bother a lot of everyday users, but my workplaces utilizes mac filtering (only way around it is to use the battery-intensive 3g option instead, and i have terrible 3g reception at work where i sit; OUTSIDE my office, i get great reception, but it's bloody hot here x.x)
in any event, if someone could help me out or give me some advice that'd be great.
to summarize:
5.0 gapps + cm12.1 = lots of watchdog events
5.1 gapps + cm12.1 = a lot LESS watchdog events, still happening though
wi-fi mac address gets randomly generated at reboot
phone doesn't get detected by the computer on usb unless you leave it plugged in and do a soft reboot (advanced reboot option; common in most cm12.x instances with default kernels; solid geeb was better, and cm11 was flawless pretty much)
using built-in kernel
att jb radio
clockworksmod touch recovery, the last one (6.0.1.8 i think? it's the last one on their website)
4 gig micro sd card is in the slot, if that makes a difference
one more note: i'm having far fewer crashes on this new install maybe because there are only google related apps (other than whatsapp which i installed right away). future planned apps to be installed:
adobe acrobat
battlenet authenticator
es file explorer
facebook messenger
titanium backup
mx player
aedict japanese dictionary
busybox
greenify
orpheus music player
qr code reader
skype
supersu
terminal emulator
any increase in instability henceforth i'll let you know. also for anyone NOT having greenscreens on the e970, do you have whatsapp? if NO, interesting. if YES, still interesting, but please what version? mine's not the latest (yet)
blitz9826
so this is new:
after reaching 100% battery level on charge, the phone used to cool down. ever since switching to this rom, the battery DOESN'T cool down, it stays warm/hot. i know for a fact it's not a charger issue since i'm charging it with the same usb port as i have been in hte past (and every other phone for that matter on the same port)
any ideas?

sensors
Sensors isnt working. 28.04 build.
Will you fix it?
Icons are blurry?
Hey. Loving this ROM so far. Only problem is that the icons are blurry (not HD as usual). I wiped the cache and delvik cache but it's the same problem. Anyone know how to fix this? Thanks.
ronasimi, i am waiting, that you will read this. Please try to fix sensors in your unofficial 12.1 builds. I really want use your rom, but sensors is not working.
I have e970 with mako z30f bootloader, and latest twrp.
Auto rotation
The auto rotation is not working. Only staying in portrait. Can anyone help?
Mobile Data to Wifi Switching
@ronasimi
first of all thanks for the Great rom im using from almost a month with no issues at all.
Just a little question about wifi. Wifi did not connect automatically when my phone is locked. I've to wake it then WiFi connects immediately.
same is when im using mobile data and saved WiFi is in range. but phone will connect it,until i wake the device.
please help me out on this.
[SOLVED] Problems rooting 12.1 E971
Edit: For anyone else facing this issue, flashing the beta version of SuperSU from a custom recovery works.
On a previous 12.0 build I was able to get root just fine, but after clean flashing the latest 12.1 build no method seems to work. I've tried flashing the latest SuperSU update zip from TWRP, using adb to push su and busybox, and using the built in root in developer options.
Flashing the zip and using adb result in SuperSU saying there is no binary installed, and with the root in developer options it never pops up something asking for permission.
Has anyone gotten root on the latest 12.1? Thanks in advance.
Cm 12.1 Bluetooth Issue on E971
Thanks for the great rom. Works great except one minor. Bluetooth connection on and off consistently.
I have cm-12.1-20150521-UNOFFICIAL-geeb.zip rom installed.
Thanks!
Thank you for your hard work on the ROM.
On an E971 with a clean flash, as others above have reported, the sensors/auto rotation are not working.
Another request would be to add repo specifics on your description of the ROM at the start of the thread. You link to your github account where the repos are stored but there are many of them, some with similar names. I am interested in reproducing your build process and possibly contributing some changes, but I am not sure which specific device, vendor and kernel repos you are using to generate the build. Would love to get rotation sorted out and keep development going on this solid 5.1 option for a still capable device.
Still kind of suprised that CM isn't doing 12.1 builds for E973/E971 but it seems they have dropped a large number of phones with the move to 5.0/5.1 and angered a lot of people.
Thanks!

[Kernel] FPBug: First really stable 4.x kernel for the Galaxy S2 i9100

FPBug: Meet the very first stable kernel for the Galaxy S2 i9100, S2 AT&T i777, S2 Epic 4G Touch d710 and Note n7000 since Gingerbread days
Every single Android 4.x kernel for these devices has had a serious bug (FPBug) that randomly corrupts the state of processes, starting with Samsungs's stock ICS and JB and spanning every custom kernel out there newer than Gingerbread.
STATS: 500+ kernel downloads in 2 days, wow!
RELATED: Make sure you check out my TRIM-enabled kernels updated with the FPBug fix.
UPDATE: A fix for FPBug has been merged into CyanogenMod's cm-11.0 branch! The fix has not made it to the stable/cm-11.0 and cm-12.0 branches yet. Changes: this one and the previous 12. Commits: this one and the previous 12. The 20150111 nightlies are the first official CM 11 nightlies to incorporate the fix.​
A little bit of history
As Android got more complex, the effects of this bug grew more visible, to the point of making the platform completely unstable for some users. Complex apps would fail for no reason, GSM, 3G and WiFi connectivity would randomly be lost, music playback would stop and require a reboot, camera would fail, internal storage and SD cards would become inaccessible, installed apps would disappear, users would experience battery drain issues ranging from inability to enter deep sleep all the way to phones becoming very hot, and the list goes on and on.
These failures all seemed unrelated and their cause was very hard to track down. Partly because events happened randomly and were not reproducible, but mostly because the bug undermines the very assumptions programmers deal with when creating any kind of code. And so years passed and the common cause of all this pain was never identified. Many ROM developers abandoned the platform out of frustration.
Then finally this past March, when analyzing the random loss of access to storage, user cgx observed a corruption event for the first time, and a connection between all these unrelated issues, sometimes hypothesized, was suddenly found. The corruption seemed to have happened in the stack, but it was later suspected then confirmed that the corruption actually happened directly in the registers of the floating point unit of the CPU. Yet processes that did not use floating point at all were also affected, because the GCC compiler typically spills registers into the FPU and uses FP and NEON instructions for optimization.
These findings allowed the creation of a stopgap fix for the "music bug" that shielded the FUSE process (which manages access to storage) from corruption in the FPU. The fix was widely applied and effectively eliminated all bugs resulting from sudden loss of storage access and returned the platform to pre-Android 4.3 stability levels: ie, sort of stable enough to be used as a daily driver. Later a working detector for the elusive bug was made and it was confirmed that all kernels since Gingerbread were affected (a thing that was already suspected given that the FirefoxOS people had described similar symptoms in 2012 under stock Samsung ICS). Finally enough of a root cause was hypothesized and a fix was worked out. And if this were not good enough news, user Entropy512, the exynos platform hero who saved us all from brickbug, has hinted that official Lollipop from Omni is now a possibility.
A short description of what the fix does can be found here.
Update
User zeitferne worked non-stop throughout this weekend and made amazing progress. He found a couple of missing commits that are apparently needed for the FPU state tracking to work through power state changes, he discovered that the FPU in CPU0 is the one that actually gets the corruption, he found an explanation why this bug never affected the 4412 platform (Galaxy S3, Note 2, etc), he narrowed down the conditions for the corruption, and finally output an alternative patchset that apparently fixes the FPU state restore optimization rather than just disabling it as mine does.
Kernel developers are encouraged to merge his changes in lieu of mine once enough testing is done and @zeitferne green-lights the patches. This is important as it might fix as-of-yet undetected bugs or prevent bugs arising from future changes. In the meantime, eager maintainers can merge my fix which is by now well tested. Users will only see a small (<< 1% ?) performance increase with zeitferne's patchset and don't really need to bother with this; my advice for them would be to wait for the changes to trickle into their kernel of choice. AMAZING JOB ZEI!!!
2nd UPDATE: @zeitferne has green-lit his patchset! Kernel maintainers merging it please take note: 1) Make sure my fix is removed before applying his, otherwise there will be a small performance hit in the resulting kernel. 2) Both our fixes also affect the 4412 platform (i9300, n7100, etc) in slightly different ways, and the effects of this have not been properly tested. I must recommend that some testing be done before distributing FPBug-fixed 4412 kernels. Please report your test results back to this thread.
WARNING: A problem was reported with zeitferne's patchset.
FOLLOW UP: @zeitferne made some changes to his patchset and initial testing looks good.
AND FINALLY: The patchset was merged into cm-11.0! (See this change and the 12 previous ones.)​
Downloads
You will find kernels for various CyanogenMod releases, M-snapshots and nightlies here. These kernels are guaranteed to work only with the exact matching version of CM specified in the last part of their filenames. But in reality they should work with most versions of CM that are close enough. (Don't ask me about this, I don't know, I don't even have any of these phones! Just try them and see for yourself if you are feeling a little adventurous.) For other ROMs i expect this fix to be merged in a matter of days after some more testing is done. Please be patient, and KitKat users can flash my music bug fix in the meantime.
FAQ
Q. I have flashed your music bug fix in the past. Can I flash your kernel?
A. Yes! The music bug fix has no downsides. In fact, as a side effect, that fix makes your phone slightly faster and saves some battery so it should be merged in all ROMs IMHO. If you already have it installed leave it in place, but do not flash it again the next time you upgrade the OS. Please do not flash it just for the sake of optimization: since it is based on CM11 M10, it would actually be a downgrade.

It's not about i9100 ? Right ?
Can't wait till testing is complete and you merge the fix into your trim kernel for the i9100 lanchon. Thanks to all the programmers, testers and commenters in the bug thread for their hard work.

@Lanchon thank you very much for ur hard work [emoji122] [emoji122] [emoji108]
Dammit... Never wanted to use CM again... I think I will have to at least for now until it gets integrated in other kernels
Great Job @Lanchon
i never had any GPS problems on my i9100 before ICS. Since JB it has gotten sooooo much worse. I tried atleast 20 different ROMs (JB, KK) and 5 different Navigation Apps. Nothing helps. Currently i am on CM11 M12 Snapshot. Still not better...
Could this kernel also help me with the GPS Problem??
so no bad battery life any more?

No it won't solve gps problems. I've had good luck using GPS status https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2 and Faster GPS https://play.google.com/store/apps/details?id=org.fastergps from the Google play store. GPS status will download assistance data (A-GPS) and faster GPS setups the proper ntp server for your area. I get fixes in about 10 seconds now.

Everything is somehow faster with this kernel. I flashed the music bug fix with this kernel. Waiting for trim kernel, it will further accelerate the phone.
I noticed that the phone is not heated as before.
You're a genius because you've done a lot for us, s2 community ... And we know that you do not own this legendary phone
Thank you @Lanchon

What recovery does this kernel has built in? I use 11.15 cm11 custom build my markox and I want to mare sure that I can reflash the rom in a recovery if it screws up. I never used Odin since I got this phone.

Lanchon bases his kernel on stock cm kernel, so cwm recovery is built in.

[ROM][CM14.1][UNOFFICIAL] Samsung Galaxy Tab A 7.0 LTE SM-T285

*** This project is now abandoned in favor of the LineageOS variant ***
This is a port of Cyanogenmod 14.1 for the Samsung Galaxy Tab A 7.0 (2016) LTE SM-T285. Cyanogenmod needs no introduction, it is one of the most popular aftermarket ROM distributions around.
5.1.1 is the best that you can get from samsung right now and it is not known if they plan to do any upgrades. I have absolutely no idea why samsung chose to stay with the outdated 5.1.1 mid 2016 when we already got 7.1 coming out. This custom rom is probably the best you can get if you want an upgrade from Lollipop. Performance on the latest build is also better, you be the judge.
As this is the first CM-14.1 release, I don't recommend you use this as a daily driver, but it should be good enough for some. Make sure you read the pending issues below and decide if this is acceptable to you before you flash this rom. This rom probably won't get much use out of some people until bluetooth is fixed.
Based off on Cyanogenmod 14.1 sources which is based on Nougat 7.1.

Update Dec 3, 2016
===============
Fixed GPS, Wifi Hotspot, Graphics issues, Calls, Camera,sdcard is now marked as adoptable.
Works:
- Wifi/SMS
- Audio
- Graphics with glitches (minor screen tearing, blank screen showing up on overlays)
- GPS
- Wifi Hotspot
- Incoming/Outgoing Calls
- MTP
Does not work:
- Bluetooth
- Camera
- LTE (Due to APN issues)
- Battery Meter not updating
Bugs/Known Issues
* Problems recording video
Other Notes:
- selinux permissive
Most of the issues are fixable, I just need more time and encouragement
SM-T280 Users: Unfortunately this rom would probably not work on it since the SM-T285 and SM-T280 have different kernels and slightly different hardware. I don't have access to this device so it would be hard for me to port it over. However I believe there are a lot of similiarities in the device tree that can be shared. If a dev with the SM-T280 is interested I can probably help.
Download
========
Remember flashing an unofficial ROM on your samsung device will probably void your warranty, Samsung representatives will probably not be able to help you as they are still stuck at 5.1.1 land as of now and have no idea how to handle a SM-T285 that is running 7.1.
As always flash this at your own risk. Make sure you have a copy of the stock ROM so that you have something to fall back to, which is highly the case when using an experimental rom.
See DevDB download section.
BUILD12032016
Note that this rom is pure stock and does not come with the Play Store or any Gapps, I suggest you download a micro gapps package separately and install it via recovery.
There have been reports that recent versions of open gapps don't work properly, it is advised to use older versions instead (e.g. open_gapps-arm-6.0-nano-20161109.zip)
Installation Instructions
==================
Perform a backup of all of your important files. This ROM is experimental and I will not be responsible for your loss of data.
Download the zip file and extract the tar.
Use Odin/Heimdall to flash the tar file to your device. If you are coming from stock oranother rom make sure you wipe first using TWRP. Coming from a previous version of OMNIRom for SM-T285 may not require a wipe, however please perform a wipe if you encounter problems.
Root and customization
===================
This ROM is a purely based on source and is not rooted out of the box. However you can easily root it by using TWRP to install the latest version of SuperSU.
If you want to customize this ROM and repackage it you may use this guide as a reference.

Nice job!!!
Great job! The ROM is impressively fluid, and I particularly love the way it renders fine text, which I appreciate because I prefer DPIs of 140 to 160. Unfortunately, just like in the early iterations of OmniROM 6.0, the tablet will not connect to the internet over cellular networks no matter how much I tinker with APNs. It's a great build, nevertheless, and I look forward to future releases.
Thank you !! Will give it a try.
posting here too (as did on omni - realized this is the cm 14.1 board)...
"briefly tried the cm14.1....much better very fast response-on the omni the pull down was an issue (would also ask me to format the sd card)
noticed here too the signal tends to drop in and out (wonder if it is some power saving going on-it goes to full strength during a call)...speakerphone also does not work here but must say this is better than the omni even though data does not work"
keyboard much better here too
on both cm14.1 and the omni, the dialer tends to be have some lag when pressing the numbers (do it too fast and can get many errors)-minor thing understand this is an alpha and the omni is a beta
thanks
I can't get Soft Keys to work, worked fine on the Omni ROM, only problem I have come across so far.

needs some xml changes that needs to be compiled into the framework for that I believe. Though there are more critical bugs I need to fix with this 7.1 rom.
I wish I could help in some way, appreciate your work.
thank for your awesome work, but i cant download any app from Playstore, it's downloading for a long time, i tried many way to force it works but nothing change. Have any one meet this trouble?

Try using an older gapps package like from october, recent versions seem to have issues.

Thank Jedld, i has tried 27th,october version and it WORKS, thank.
I used the version as recommended in the Omni ROM, which was from the 9th of November, no problems with the app store or downloading apps either.
Any closer to another release ?
Nougat will take a while unfortunately

not knowledgeable here on CM and how things are done but those links for the CM...looks like they got merged just 6 days back. Or maybe these are not relevant? just asking/wondering thanks

Those patches didn't help unfortunately Though I've fixed network type selection in CM-14.1 already, unfortunately data connection still won't come online due to errors related to APNs. Seeing as this was working perfectly in CM-13 this could be a CM-14 or Nougat related change, it will take a while to figure out what that is. As for bluetooth I was able to get it to turn on, however it is still unable to detect/pair to any device, this is also something that was working in CM-13.
any hope on porting this to t280?

I don't have the T280 so I wouldn't know. There are devs that are trying or have tried to work on it, not sure about their progress.
