[OFFICIAL] CyanogenMod 12 - Tilapia [ext4][f2fs]

[linuxxxx]

cm-12-20150206 also bricked my device.
Steps to reproduce:

1. Installed current TWRP (2.8.4.1)
2. Factory reset + converted cache and data to f2fs
3. Installed cm-12-20150206 + gapps

CM12 booted fine and i enabled root + installed some apps. Then i tried to reboot to recovery.
- recovery hangs at the "teamwin" logo (waited for 10+ minutes)
- normal boot hangs at the google logo
- bootloader works, reflashing recovery from bootloader doesn't change anything

OK, i can confirm this issue. How to unbrick: get factory images and from bloader run
fastboot erase userdata
fastboot flash userdata userdata.img
fastboot erase cache
fastboot flash cache cache.img
This will reset ur data and sdcard partition. I suggest u to try to use an older twrp (I tried 2.8.3). The nightly is not the problem, it looks like twrp f*c*s something when it boots. I'll give a look at this asap

Thanks!
The factory image wasn't even necessary, i just flashed TWRP 2.8.3.0, rebooted to recovery (which worked now) and formated /data and /cache with ext4 (TWRP 2.8.3.0 doesn't seem to support f2fs) - everything fine now

So if I flash/update using flastboot boot twrp.img leaving the CM recovery flashed as main recovery, will I get in troubles?

EDIT: I'm on 02.05 with CM recovery already flashed

With ext4 + twrp 2.8.3.x you'll have no problems. I'm investigating on this issue with grouper maintainer, we hope to fix this asap and before m1 release

a small update, i tried the following:
- flashed TWRP 2.8.4.1
- formated /data and /cache with f2fs
- reboot to bootloader and flashed TWRP 2.8.3.0
everything seems to work, rebooted several times (system and recovery) and no brick yet.

for me it looks like TWRP 2.8.4.1 messes something up when it starts while f2fs partitions are present (i didn't test TWRP 2.8.4.0)

Yep thanks..

So it should also be safe to flash CM recovery and then wipe/format f2fs/eventually flash ROM files using fastboot boot twrp.img

Just installed. Now i'm downloading alla my apps from play store, no backup of previous settings or app. Let me use it and update the ROM.
P.S.: i' m using the last nightly.
Coming from stock rooted with twrp 2.8.4.1, factory reset, changed file system trhough twrp for data and cache, installed from USB with otg, it is working

Kernel

Ciao to all
I am using a custom rom of SYNMAN with Carcosa a33 kernel both based on 5.0.2 AOSP
My friend BRAINVISION is using CM12 and he is very happy about battery drainage and performance

May i extract boot.img from this CM12 and flash it on my system ??
Or i will have explosion ?

 

[x-system]

Hello. Yesterday I flashed cm12 (2015.02.07) and was problems whith very long charging.
If tablet is off charging is normal.
How fix it byg?

What kernel is slow battery drain?

The charge time has been slowed down from Google on aosp 4.3 because of he issues (AFAIK)

Flash the whole ROM. Its safer

hey guys can you please show me a screenshot of the notification drawer with a few notifications on with the default CM12 theme and style?

I applied a bunch of different themes and now it seems that the default one is messed up.. don't know, but I remember white background - sorry I mean light grey - with dark text for notifications.. While now I always eve dark background, even with the default style.. rebooted tons of times!

thanks guys..

 

[x-system]

What you think about 5.0.2? What better for good performance and battery drain? 4.4.4 or 5.0.2?

 

[brainvision]

OK..

don't know why and don't know how, but it really seems that afetr applying a bunch of CM themes the original framework messed up a little bit.. Original colors on notifications and original notification bar buttons were gone, lost.. I rebooted a lot of times to be sure that the default theme was fully applied but nothing changed..

now I want to start from scratch again, for different reasons..

so I have a question related to TWRP issues with f2fs causing bootloop..

as other users reported ATM safe steps are:
1. flash or boot twrp 2.8.4.1
2. format /data and /cache with f2fs file system
3. flash permanently twrp 2.8.3 (but maybe also 2.8.4.0, that does NOT have f2fs support, but it's not sure it will work)

and that's OK.. but what about next nighties updates?
how should I update so that I wouldn't lost f2fs support but without boot-looping again and again?
TWRP 2.8.3 does not have f2fs support: what would happen if I dirty flash a ROM and GAPPS with such a recovery? It should not be an issue 'cause /data and /cache partitions should remain untouched.. am I right? Even if I need to wipe cache and davilk?

Does someone know something about all that?

thanks guys!


EDIT: so I can now reply my own questions..

If you use f2fs partitions there's no way to update, nor via twrp 2.8.3 nor via adb sideload: the process fails when it tries to mount /data partition.
This old version of twrp doesn't support f2fs, so it isn't able to mount data and cache partitions!

So I choose to go back to etx4 partitions.. [emoji27] [emoji27]
At this stage nighties are too much important so I prefer to be able to update..

yep, for f2fs users TWRP is not working and pretty much useless. If you want to update use EXT4 or wait for a TWRP fix.

Dear,
can you do a test with ANTUTU with your N7 TILAPIA and CM12 in ext4 and (if i remember weel) with Carcosa Kernel ??
My N7 TILAPIA with Synman + Carcosa has a score around 24000

No, dear..

Still on CM with standard kernel.. I had to flash everything from scratch 'cause I formatted /data and /cache partitions to ext4 again..

Antutu score on 02.05 build with f2fs was 19.920 or something like that..
I'm going to do the same test with 02.08 build with ext4, but I bet it would be pretty the same..

Later, this afternoon or maybe this evening I'll finally flash the carcosa.a33..

 

[paolocorpo]

Great
I am sorry for your issues related to f2fs sytem
I am waiting for you news about ANTUTU's test and for your 3D dedicated to this rom on Androidiani forum
Ciao

 

[brainvision]

?

Don't think I would have time to follow a dedicated thread, that's the reason why I still haven't created one for the official CM12 into the forum you are talking about..

BTW, tests done..

First Antutu test was pretty the same as with f2fs: 19.535
Second one was much lower: 18.971..
And a third one: 19.729...

So it really seems that f2fs file system works and it gives this device a little help when talking about performances, even if only related to read/write access to the nand memory.

I think o have to absolutely try the carcosa kernel..

 

[paolocorpo]

I am sure that you will found necessary time to create a 3D ...
I am waiting for your upgrade to Carcosa a33 and its new test

Benchmarks scores may not be perfect because of cm profiles that haven't been fully enabled on tilapia (I'm Woking on this), and keep in mind I won't support anyone with custom kernels
