[ROM][7.1.2_r24][Grouper|Tilapia][8July2017]CarbonROM CR-5.1 Unofficial

daniel_hk · Sep 28, 2016

CarbonRom is an aftermarket firmware based on the Android Open Source Project.
Click the logo to visit the official site and Features

After trying a number of custom ROMs, I decided to bring up the CarbonROM again. Almost everything is working now. The essential feaures and the CarbonFibers are also implemented. You might not like the navigation bar's arrangement but there is the "System UI tuner" to customize the look. The official features page is old and there are still more for us to explore.
It's for now the best N for my daily use. I had built Carbon before and it's good to be Carbonized again. Cheers

Screenshots: :cowboy:

Known Issues:

　1. Video recording not saved
　2. Some apps might not fully compatible or required update.
　3. Please report.

Dear daniel_hk, I just tried to install it and the first thing I discovered is, I cannot turn on USB modem. Do you know of any other ROM for Tilapia (maybe even preferably Marshmallow) which permits to do it? Or maybe you will fix it in this one at some moment?

gaetano76le · Sep 28, 2016

Hey,

I want to install this rom but i don't undersatnd how to have the root. Do you have a link ?

I assume you meant the USB modem which connect to a land line. If not, that means I don't think I may help.
First of all, you need a kernel that support your modem's chip. That is the (Linux) driver of the particular modem you have. All available kernels for our N7 are derived from the one Google released. It might be included as a standard Linux driver in the source but I don't recall anything like that. I can't see anything to "fix".
Since you have your USB modem in hand, only you know what you have. You may try to port it yourself and share.

Here is the development forum which is for those have some experience. I think you're new to these. You would know if you have some experience. It is irresponsible just giving you the link. You might soft brick your device if you don't do it right.
If you are really sure and confidence, you may get the latest SuperSU under the superSU threads here in xda-developers.com.
You better do your homework and read first. There is no free lunch, rush for results won't necessarily speed up the process. Asking for link is a kind of laziness. If you brick it, how many blames to the others won't help.
Good luck.

Dear daniel_hk, thanks very much for the fast reply! No, I actually mean the USB tethering, the thing in the same menu as Wi-Fi hotspot. The latter seems to be working, at least it does get turned on. And the USB tethering does not. So is there any way to get around it? Actually I would more willingly use the Slim6 ROM but I encountered the same problem there...

abhifx · Sep 28, 2016

As of now best nougat yet again. Doesn't seems to slow down and is more fluid.

OK, got it now. I'll take a look later.

Misunderstanding could easily lead to a heated argument. I'd been called names because I didn't know "Menu" refer to App drawer. Sometimes I'm just too stupid to know what the question mean.

A little bit more explanation or just a screenshot with captions might clear things up...

Edit: @DonSanches I just checked, USB tethering was never implemented in AOSP for Tilapia. I don't know if any existing ROM had implemented it. I just tried and managed to make it work. I'll include it and Bluetooth tethering (haven't tested yet) to the later builds (including Slim6 and others). Cheers!

Umm... Flashing gapps just brings it to a crawl. Will flash afresh. @daniel_hk have you incorporated the new omx fix? Have not tested any video playback yet

This is for sure. I usually update all the branches at the same time.

OMG, this is so cool to know! If you knew how much time I wasted in fruitless searches! Thank you for resolving the mystery for me (I actually started to suspect something like that). Looking forward to that update!

ok bug report.. tablet charging is extremely slow, in fact i have to charge it while its off. any stop gap solution for this?

It is not kernel related. If you check the log, you would find that the batterystats service is unavailable.
In M, I used a custom HAL service to turn on the polling of battery status. N added the charge current fields which are not yet handled and the service fail. The charge current might limit to standard USB now. I already fixed that.

When porting the kernel to N, I found the android_alarm interface. Which might turn on a switched off device (may be schedule ON/OFF too). This interface is also handled in the same HAL as batterystats. I was playing with it and I haven't removed it. Hoping I might keep both later.

Man that is fast! I am in love with smoothness of this ROM. I hope next update is carbon only. Well maybe every other rom be as smooth with your hard work

Edit: @daniel_hk would you be kind enough to provide a patch for charging issue? using as a car tablet is a tad difficult because of this.

daniel_hk · Oct 4, 2016

Since Carbon is comparatively complete, I keep it up to date first.

20161004 release is out now.
Change log:
　- Kernel: DT2W: a more reliable approach
　- Kernel: DT2W: Resume power state after a deep sleep
　- Healthd: Fix the BatteryStatsService, battery icon shown in QS now
　- Healthd: Fix the detection of Charging source

Can you consider it stable has a daily driver ? Might give it a go but i just finished customizing my 6.0.1 setup. Do it support CM compatible theme ? I might also need to wait for my theme to get update...

Amazing Rom

This rom is amazing I use my nexus 7 in my car as my infotainment system and this rom is super smooth, I got a quick charge in my car and everything is good. I still can't get a GPS fix though, tried everything, re-flashed the rom, tried a couple of GPS calibration apps; no luck. If you can point me in the right direction it will be greatly appreciated. Thank you for this rom

It's my daily driver now but it doesn't have theme yet. DU-11 have theme but its still early. If its your daily driver, I think you may play with your 6.0.1 for a while.

I have a Tilapia. I can't access the Google services locally so I can't use apks like Google Map. Here are some of the apks I tried.

A compass apk and a navigation apk. I was facing north in the balcony so only the northern sat. can be locked. Anyway, it's working fine for me.

I was using GPS Status since my first Android device. But, its compass seems not working in my Tilapia and the MTK devices. It's background process would retard the system for a while. Those Qualcomm devices are OK. I think its blob related. I just pick those working apks on my Tilapia now.
Should I had put a wrong blob to Grouper, the log would show some errors on GPS. If you found something, you may include the log here for us the study.
Good luck!

its actually pretty stable and fast (yes.. first ROM that feels smooth).
GPS does seem wonky but then i have not tried much.
@daniel_hk charging still seems slow as screen plus charging still drains the battery, but is better than before and does correctly register as charging from AC and screen off charging works (although slow). i am using a 2amp charger.

First of all, it's a great ROM.

Bug report :
#1 : Google Maps is really slow and unusable with the September build of the ROM.
#2 : MTP process is crashing every once in a while.

I have a Grouper device. without SuperSU.

I don't know why though.

Maybe the CPU of the tablet isn't beefy enough for the newest versions of G Maps...

Thanks.
