Who's back? We're back.​

CarbonROM is an aftermarket firmware based on the Android Open Source Project. We are dedicated to fast, stable, and feature-filled roms, honesty and communication with our users, and openness with our code. We like frequent builds, with the very latest and greatest hardware support and fixes. We strive to not only provide you with the best rom we can build, but also to give back to the Android community and our fellow developers. For us, this is about creating something we can be proud of and hope you will enjoy.

Please feel free to look, build, and use our code at CarbonROM's GitHub... and at CarbonROM Gerrit.

Disclaimer:
While we make every effort to test these builds as much as possible, we are not responsible for anything that may happen to your device, family, pets, or perception of reality. We ask that you do your part to know your device and know how to recover from problems before you flash! If you have questions, ask your fellow users or ask us in #teamcarbon on freenode IRC.

Support:
We spend an astonishing amount of time developing this software. We can't spend much time on XDA as a result, so if you need support, please try the following:

1) Search. Search, search, search. Yes, you. I don't care how unique or important your question is, it's very likely someone has adressed it already. Especially if you're even close to new at this.
2) Read our FAQ, which can be found on our website. Carbon FAQ
3) Ask a question in your device forum. Someone will no doubt try to help you. Warning: this help may come in the form of telling you it's a dumb question that has been asked before. See step 1 - such are the perils of asking questions when you haven't done the research yourself. Android is about helping yourself.
4) Ask a question on our IRC channel. Connect to #teamcarbon on irc.freenode.net or click here. You'll find several other Carbon fans and usually one or more devs as well. Please be polite.

Hi,

Super! I think lots of people will be glad testing this new ROM.

On the latest build (July) of Carbon ROM/Castor LTE I had a lot of problems connecting to some Wlan Access Points. Seems that the authentication (cipher???) do not work. Could it be that the Wifi implementation was/is not complete?

Is this fixed in the builds here?

Hey rcstar 6696,

thank you guys!

Is the castor-lte -testBuild Version stable enough with wifi / no reboots?
I know, the Official castor (LTE) are Not available yet, but what you think you will release it? Please no stress I need the Infos, to plan free time for a flashing-day my three Castor Tablets

thank you for your hard work

At first glance:

• auto power down fixed, no more!
• wifi disabled at config wizard, still present (quicktoggle workaround works though)
• sometimes touchscreen freezes and refuses input (put screen off and back on fixes it)
• snappy rom, pretty fast, no big issues found!

Thanks for the hard work on this rom! Finally a decent AOSP Rom for my Z2 Tablet.. :victory:

Yeah first was a tricky bug but it was due a Sony change in kernel which killed power code in kernel
Will try to fix wifi issue should be easy
The touch screen thing is Hardware releated i know from some guys that stock sometimes is not working too

Yes this is also in stock ROM, so probably kernel related.. Also saw some build.prop entry for the touchscreen, maybe that's causing it..

Battery drain issue is still present... Maybe it's a battery charging issue ..... But with stock ROM I had no battery problem, only with twrp recovery and Carbon ROM.

Show and explain your battery drain please ?
Btw wifi issue with setup wizard is fixed in new build

I read in OP:

Is this also needed when coming from, say, latest rcstar6696 LineageOS?
Thanks

I posted on lineageos thread the screenshot of carbon ROM battery drain.... From 100% to about 60% battery drain is standard....but when arrives to a lower value, it drops in few seconds and tablet shut down.
I really don't know and don't understand why.....with stock and Lineage I had no problem.

From 65% to 0% as fast as StarTrek teletrasportation ......

Good job @rcstar6696 just finished unlocking, twrp and doing my first boot!

[Micromind]

First boot wasn't successful, my setup wizard kept crashing after choosing language. i downloaded arm gapps 7.1 nano.
I flashed supersu so i will try once more without it. Then i will try beans gapps

Try to click on WiFi icon to get connected (click click click and click again when error disappears to open drop down menu) and wizard will end with no error....

No if you come from lineage you don't need stock before flashing carbon. Only wipe data and system.

Yeah its a known issue from opengapps. Fix is made and will be included in next build. Not sure if it goes in next weekly but my next test build will have it
