Well, thanks for your answer but I found out what it was. Strangely, the downloaded file matched it's MD5, but when i copied it to the SD card, it corrupted it (@##%%^^ reader!) so I copied using another reader and I'm flashing it right now,
[Xperia Arc Android Development] masteriori:
For me, Urushi build is corrupted. I have downloaded on two different browsers (Chrome and Opera) and still doesn't seem right.
[Xperia Arc Android Development] Langes:
FYI: http://xdaforums.com/showpost.php?p=60741830&postcount=627

Did you compare the md5sum of the zip file you downloaded with the md5sum found in the md5sum file? Is your zip file approximately 260MB in size? Correct me if I'm wrong, but I suspect you downloaded an unfinished upload.
[Xperia Arc Android Development] masteriori:
Thanks for the tip, Langes. Now I can finally confirm my suspicions because MD5s don't match so what should I do now, wait for re-upload? Before, the filesize was around 170MB and now gone up to 250MB so perhaps it's still uploading.

Thanks

Any chance you could bring back control over Governor? On Balanced mode, it is lagging for me so I wanted to increase maximum frequency to 1.2Ghz and not resort to Performance mode which would kill my battery in no time.

Integrated CPU control seems to have been removed from CM so it's not mike's fault. Just download 'No-fills CPU control' or any of the many apps that lets you change it.

Hello,

I have an Xperia Arc (LT15i) with the stock rom and the 8gb sd card class 2.

Today I can not update google apps by lack of available memory. Yet I maximized the number of displaced application on SD card. Except it only remains for me that google app ... Can't install anything more.

Also, my phone is very slow. The sms window put 15 seconds to open, the browser is slow and eventually crash, google map worse. Even the call window put 10 seconds to open.

If I understood correctly, cyanogen no longer uses the small main memory but moves the system data to the sd card?

I would like to give a second life to my phone but it is a small investment: A card class 10 to buy the price of unlocking the bootloader with Omnius.

Can you confirm that with cyanogen 12, I can reclaim space, update my applications, and especially less be slow?
[Xperia Arc Android Development] evil.demon_s:
If the issue is only of less space then you can partition your sd card and connect the secondary partition using link2sd while using stock rom

No need of cm for this

Only requirement will be rooting your device

how to make a complete copy of the system after installation CM12.1 ?

For example:

1 Install CM12.1

2 Set all the parameters the firmware

3 Install many applications

4 Make a backup system ???

PS

- in CM recovery no item to make a backup

- Titanium Backup not suitable for these purposes
[Xperia Arc Android Development] foxvengeor:
This is not just a question of space as disponible. Its also to have a speed gain ; Although I think it may be because my memory is full my phone is slow. How does cyanogen compared to stock rom?

And obviously I'm not against having a newer system ...
[Xperia Arc Android Development] ZMaissi:
Hi! I had almost the same issue with my backup phone, a Xperia Active. At first I had a 32GB SD card class 4 partitioned (2GB to data), installed CM12.1 and tried to use it but it was almost impossible. It had the same issues that you described earlier, everything took more than 10 seconds (answering calls, sending SMS, etc), but then I remembered my daughter had a 32GB SD Card class 10 in her S4, so we traded cards. What a difference!!!, I am amazed with the speed the phone has now, everything is like it should be, responsive.

Someone mentioned Link2SD earlier, the free version works good but it has only one drawback, it doesn't links libraries (only the paid version). So, I used another one called Mounts2SD, look for it here, it's totally free and does everything.

[Xperia Arc Android Development] foxvengeor:
I do not understand. The internal memory is slower than sdcard?

Link2SD it is still useful if I install cyanogen?

I thought all the sdcard is worth for reading and class was only for writing

I don't know if it's work on CM12.1 - [RECOVERY] TWRP 2.4.3 for all your {legacy}Xperias. (downloads + DIY howto) :confused:
[Xperia Arc Android Development] ZMaissi:
Sorry, my bad. I forgot to mention that in order to use CM12.1 you MUST partition your SD Card with an additional ext3 or ext4 primary partition at least 2GB for Data partition, since this space is reallocated to System partition. What I was mentioning is my experience using different SD cards, that a Class 10 is a must. But if you use CM12 or CM11, this additional partition is optional although very useful.

Hope this helps…

Is anybody having issues with the latest sources? I had a couple of apps not responding after upgrading (weird, but apparently solved after a few reboots) and big problems with charging; sometimes I would see the spinning animation and the led would light up, but definetely it would not charge (percentage would keep going down). I had to downgrade to my previous build; this is from 31/05/2015, so it is up to date till the "android: configs: Initial commit of Android config fragments" change, with "msm7x30-common: Set dalvik.vm.dex2oat-filter=balanced" also cherry picked. After that there were only a few changes... could it be because of the kernel configuration changes?

P.S. I also use "mark SD mmc device as nonremovable", but it never gave me problems
[Xperia Arc Android Development] SGY User:
is this rom recommended for daily use??
[Xperia Arc Android Development] PeppeBove:
Yes, but if you want to be sure, go to cm11
[Xperia Arc Android Development] ajebulon:

[Xperia Arc Android Development] Vanily:
Just built rom for ray with the latest sources, don't have any issues with apps or charging, but I've built rom without (dalvik.vm.dex2oat-filter=balanced dalvik.vm.dex2oat-flags=--no-watch-dog dalvik.vm.image-dex2oat-filter=speed) this cause optimizing apps on each boot; and I use 3.10 kernel.
[Xperia Arc Android Development] devtry:
Ok, thanks for the answer. The "dalvik.vm" stuff should not be the problem (actually I use it also on the "good" build), while the different kernel might make the difference. Maybe I will try out the new 3.10 kernel as soon as I have time; I thought it was not ready yet.

For what I can read in your picture, it seems that they you didn't create the secondary partition in your SD Card or you created it in a different format than ext3 or ext4

unmount of / data failed: no such volume!!!!!!!!!!!!!

what to do?
[Xperia Arc Android Development] Black_Eyes:
have you created partitions?
[Xperia Arc Android Development] eldoctor94:
This happens probably because you have not yet made the second partition on ext4 2GB. (ASSUMING YOU HAVE A 16GB CLASS 10 SDCARD)

First, backup any important data of your SD.

Second, go to minitool partition wizard, select the SD card and delete the partition.

Now, create a new FIRST partition, in FAT32 format PRIMARY (this is for your multimedia and other), making sure to leave a blank space of 2GB for the second partition.

Then, create a second partition in the space you leave. Create in EXT4 primary (this is for the CM12.1 data apps).

Now, click on apply, wait and enjoy the installation :fingers-crossed:

PD: F2FS cause troubles

[Xperia Arc Android Development] bleached:
May I ask about calling lags?

To be precise, I have smultron and on all lollipop ROMS incoming calls (or even outgoing) lag, meaning that calling ui takes a lot of a time to load. This makes me unable to answer calls, or sometimes cancel outgoing calls before ringing.

Have you noticed such a problem?
[Xperia Arc Android Development] eldoctor94:
Me also have the same trouble in Urushi... I'll update at the last build to see if "call lag" is solved.! Althought a partial solution exists... Only active call answering with the home button...

Thank you for your superb work Mike!

If I may make a request, when posting the changelog for a new build, would it be possible to provide some additional information about how these changes will affect the phones' operation or performance etc.?

Fvor example what is the benefit of setting dalvik.vm.dex2oat-filter=balanced, or the recommended configs in the kernel, etc.?

Thank you again for your continued efforts.

[MENTION=3839575]mikeioannina[/MENTION] , the maximum volume seems to be less in all the lollipop builds compared to stock gb or ics for smultron. The mic quality is also poor. What might be the reason for this? Any way to fix this?

[Xperia Arc Android Development] eldoctor94:
Me too have the same issue in Urushi from CM9

... Whatsapp voice notes have a poor quality sound and it's LOW compared with a official GB or ICS, it's LOUDER than CM9 in forward, also the sound recorder have a low volume when recording but have a passable quality. I have seen other devices (other phone brands) with Cyanogen, have no such problems of low or poor audio quality! There will be something with the kernel or be a library that is not optimized in this regard? :(

---------- Post added at 07:30 PM ---------- Previous post was at 06:52 PM ----------

I upgraded to the latest build for my Urushi (20150607) as shown, but when the phone started, the following messages are displayed:

Google play services has stopped.

Whisper Push has stopped.

And then I noticed that Google play Store disappeared, and also I can not save new contacts and sync with my google account, only stored in the phone memory (I suspect the Gapps were deleted while updating). Tried to reboot several times and no solve. I had to reinstall the ROM with gapps again from 0 to return to normal. in reality, this is very tedious to do if I update every time ...

Here I explain my upgrade process (if doubts arise):

- Download the lastest build. (20150607)

- Flashed the boot.img from flashtool.

- Reboot into recovery.

- Flashed the update.

- Wiped cache.

- Wiped dalvik cache from ADB shell ("mount /dev/block/mmcblk0p2 /data" "rm -rf /data/dalvik-cache")

- reboot from ADB (adb reboot)

I did something wrong?
[Xperia Arc Android Development] Adam Hui:
Dont use ADB, just use cyanogen recovery

Flash rom after wiping done, reboot & flash just minimal gapps.

*] front LED holographic keyboard >> another dream in android
[Xperia Arc Android Development] eldoctor94:
Thanks [MENTION=4666525]Adam Hui[/MENTION], the conclusion would be that each update must re-flash the gapps (minimal)? :eek:
[Xperia Arc Android Development] Langes:
Next time try upgrading without wiping caches... If you get those play store errors, just flash your gapps, if you get errors not related to gapps, reflashing the rom with cache wipes may help

[Xperia Arc Android Development] emaijala:
I can't speak for Mike, but I believe the dalvik.vm.dex2oat-filter setting used to be interpret-only, which according to https://source.android.com/devices/tech/dalvik/configure.html means "skips all compilation and relies on the interpreter to run code. "

"balanced", on the contrary, "attempts to get the best performance return on compilation investment. " I believe this means that the optimization phase when booting up after installing the rom is longer and app installation slower, but the actual runtime performance should be better. My phone seems to be spending a good while optimizing apps during the first boot, but that quite alright if it improves performance afterwards. I don't know about the recommended configs, though.

[Xperia Arc Android Development] JimmyRay:
Thank you for the explanation. I haven't flashed the latest build on my Ray yet, but hope to give it a try this evening.

I intended to do it yesterday, but got sucked into looking at the gorgeous Xperia SX (a 'Ray 2'?), and seeing what kind of custom rom support is available. I doubt the KitKat/Lollipop builds can compare with Mike's work, but it may be worth grabbing a phone to test things. ;)

Planning to test this CM12.1 coming from CM11.

i just need something stable over time till i get my next phone, have a class 10 SD.

I usually use a terminal mod to odex the entire rom in CM11 for speed, works good there.

I was wondering though, considering the data partition moved to SD on EXT4 is it reccomended to odex system apps and framework?

about formatting to F2FS, is it possible to create such a partition on my SD without having a linux pc?
