Are you sure? I went through all thread and did not find a single post about 2GB sdcard so I made FAT32 partition with 512MB, and ext4 with the remaining 1.4 GB and I got the same error. Just to check the ROM which I'm try to install should be on the FAT partition and not on the ext4 partition?
[Xperia Arc Android Development] azakosath:
Did you modified the zip file (don't do that)? If not, redownload the zip file, which is probably corrupted. Check the MD5sum to be for sure for sure.
[Xperia Arc Android Development] DTFuser:
I did not modified zip file. Should I? I re downloaded the zip file and nothing changes. I tried with both zips, System-Formating-Tool_signed.zip and DATA-F2FS-Format-signed.zip. What is the difference between them? Which one should I use?
[Xperia Arc Android Development] azakosath:
You need only the System-Formating-Tool in order to format the internal memory as system partition only (the data partition now is moved in the SD card in the new ext4 partition you have made). The other zip (DATA-F2FS-Format) is just changing the format of the data partition and you don't need it. In your photo there is a line "signature verification failed", that means that the zip file you're trying to install is not properly signed. So, if you didn't modify (as you say) it must be corrupted. That's why you have to download it again and check the MD5sum to be sure that the file is correct (or just check the size of the file). (If you don't know what MD5 is, google it)

So... MiniTool Partition Wizard shows my second partition, which I created as ext4 using this same program, as ext3 after installing the ROM. My Gparted USB boot drive however, shows the partition as ext4. I'm noticing the rom pretty slow, and I have a class 10 16 GB SD card. Should I reinstall the ROM but use Gparted to create the ext4 partition this time?
[Xperia Arc Android Development] jlazkano:
Thanks for this ROM.

I am trying to install in Xperia Neo V (haida). The problem is that I can not enter to recovery.

I installed the boot.img and erase the system partition.

Could you help with this?

Best regards.
[Xperia Arc Android Development] dragongreen:
Flash the boot.img again (the boot.img included in zip that you are trying to install), reboot the phone, when legacy xperia logo appear press volume down repeatedly until the phone vibrates. Your phone should now be in recovery.

Just format your second partition to f2fs. Your rom will be more responsive.
[Xperia Arc Android Development] Neuen1:
Really? Before trying with ext4 I tried f2fs but it was even more laggy... Maybe I'm doing something wrong? I followed all the steps in the main post though.
[Xperia Arc Android Development] Adam Hui:
Make sure your max procie frequency set to 1,4Ghz. Coz at default as i remember the rom set to 1Ghz ( Arc).

[Xperia Arc Android Development] Neuen1:
Yeah, I noticed that. But I've already changed it.
[Xperia Arc Android Development] amishxda:
For me too f2fs is much slower than ext4.. but then I keeping it as its supposed to be flash friendly!
[Xperia Arc Android Development] dragongreen:
It depends on type of memory card. For me, f2fs is much faster than Ext4
[Xperia Arc Android Development] Kianush:
still there is this problem of system partition being changed to ext3 after flashing the rom, is there anyway to solve it?

I made the secondary partition in ext4 format but it changes to ext3!!!!!
[Xperia Arc Android Development] mathewgx:
ext4 remains ext4 after system formatting tool.

But when cleaning data/cache it becomes ext3.

Can anyone confirm that ?

Must be a kernel problem.
[Xperia Arc Android Development] dragongreen:
Yep, it becomes ext3 after cleaning /data

[Xperia Arc Android Development] Kianush:
Guys please help me, I messed up my framework-res.apk and now my phone gets stuck on boot animation!

please if you know know to make a flashable zip that works on cyanogen recovery, make a flashable zip with latest cm12.1 framework-res.apk file so I can get it back again

every zip I tried on cyanogen recovery gave me the error: failed whole file signature verification or something like that

pleeeeeeeeeeeeeeaaaase help me with this BS recovery

if there is a way to install twrp or cwm tell

guys Im stuck
[Xperia Arc Android Development] azakosath:
If you have made the zip file, then sign it with this tool, it works. But, why don't you flash the rom again? I think is best solution.
[Xperia Arc Android Development] Vynikal:
Mike has enabled dex-preoptimization on latest builds. That simply means it is "odex".
[Xperia Arc Android Development] Kianush:
thank you I will try it ASAP! bu come on man reflashing the rom means every single modification and app lost!!!!

---------- Post added at 06:02 PM ---------- Previous post was at 06:02 PM ----------

so could it be deodexed or will it harm in any way??!
[Xperia Arc Android Development] azakosath:
Do a dirty flash, you will loose any modifications, but not your apps or settings. It's not necessary to make clean installations after every new release!
[Xperia Arc Android Development] Kianush:
the signing was successful and I was able to flash it but then the phone went to bootloop so now Im trying to dirty flash hoping it would get out of bootloop lol

thanks again

btw I bought a silicon power u1 superior microsd for it's speed but it seems the superior speed just shows up on usb3 ports and my phone cant get even 1/4 of it so if anyone is going to buy should know that

--------------------

and any idea about deodexing the rom? because there is Sony 5.1 stock dialer ported and some other stuff:cool::cool:
[Xperia Arc Android Development] Kianush:
I deodexed the rom using lollipop deodex batch tool and replaced system folder with the deodexed one and then signed with signme tool but after flashing it reaches boot animation of cm12.1(the blue bot) but gets stuck there, any idea? how should i deodex this rom?

if anyone could upload a deodexed flashable zip for cyanogen recovery of this one:

"cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango" I would be really thankful

Hello everybody,

I am using 4.4.4 kitkat cm11.

I will try this rom but before i flash , i want to know how the battery life is.

Which rom do you recommended for the best battery life.

Sorry for my bad english.
[Xperia Arc Android Development] tillward:
My battery life is about the same as it was on cm11 (satsuma). If anything, it's better on this cm12 build, but marginally.
[Xperia Arc Android Development] brendy13:
or just flash port sony music (with audio settings from sony music), it work well on my phone..
[Xperia Arc Android Development] arpcpro:
I have the latest from 31 August but same like the one I had from April, it hangs a lot. I have to remove the battery twice a day.

Anyway, I would like to know if when I have the "Battery mode" set to balanced, the CPU speed will increase to 1400Mhz under load?
[Xperia Arc Android Development] Superrman:
arc s is always 1400mhz, most of legacy xperia is 1000mhz (even its the same cpu) unless you OC'd VIA Dev options "balanced" is like a profile, is less saving power profile (will peak to 1400 faster , less lagging) example it will peak too 1400MHZ @50% usage cpu load and save power, performance mode peak to 1400 only if @30% usage cpu) +- and save power mode if 90%usage , and if is 10% it will stay on 200mhz (its all Approximate+-)

i downgrade to cm11 because cm12.1 still laggy and no bright torch flash mode, no good xposed support, and no real HD video(480p fake720i) and answer call its the other side, and the sound is less loud)

sorry for bad grammars
[Xperia Arc Android Development] Superrman:
Xposed

anyone manged to successfully install Xposed? on this rom? i tried every SDK22 via recovrey and still

bootloop\stuck@boot

i giving this ROM another chance

not working xposed is want of the reasons i rollback to kk

i want many things only Xposed can do

like active secret call recorded options in CM roms (worked at cm11)

gravitybox etc for notification and stuff
[Xperia Arc Android Development] BigBenlolz:
I don't think you can make it work.
[Xperia Arc Android Development] Neuen1:
I managed to get past the boot animation once when Xposed for Lollipop was still in beta, but the phone was really slow and was showing a low space warning in the notification bar even though I had plenty of space before installing Xposed. The Xposed app (Alpha for Lollipop) refused to find any repository despite having Wi-Fi activated and access to the internet so I couldn't even test anything. I tried wiping cache and dalvik-cache but neither of them worked, I was still geting the low space warning and the phone was still slow.

I tried the official Xposed for Lollipop when it came out but couldn't make it pass the boot animation this time.

I have a Mango by the way.

I have problem with formating sdcard. I have used 2GB sdcard on which I had 512 MB FAT32 partition and 1.5 GB EXT4 partition and ROM was working. I bougth 32 GB sdcard and I want to have 30GB FAT32 partition and 2048MB EXT4 partition. But when I from recovery try to install update I get message

could not detect filesystem for /dev/block/mmcblk0p2, assuming f2s2

mount: failed to mount /dev/block/mmcblk0p2 at /data: Invalid argument

But if I on the same 32 GB card made 512 MB FAT32 partition and 1.5 GB EXT4 I can install ROM without any problem. So does anybody know how to work that problem out?
[Xperia Arc Android Development] DTFuser:
Come on guys I am struggling for more than a week. Without any problem I was able to install ROM on 2 GB class 4 (512 MB FAT 32, 1430 MB EXT4) but it was slow. I bought 32 GB class 10 SD card and I have tried any possible combination of partitions and I still keep getting errors:

could not detect filesystem for /dev/block/mmcblk0p2, assuming f2s2

mount: failed to mount /dev/block/mmcblk0p2 at /data: Invalid argument

Can anybody suggest what to do next?

[Xperia Arc Android Development] paulholland:
Did you already try to use different means to partition / format? Something must be wrong with either the hardware or the software you are using. E.g. if you are using a smartcard reader, then try to partition / format the card with your phone - either directly via the terminal or via adb.
[Xperia Arc Android Development] DTFuser:
Something is wrong either with hardware or with software, that is for sure. I don't think that hardware is the problem because 32 GB card I can use with other devices. It might be partitioning or software problem and I dont have knowledge to determine which one is the problem. If I use

510MB FAT32/1430MB EXT4 partitioning I install ROM and GAPPS without error but after that I stuck in a boot loop. I read somewhere in the forum that for class 10 SD card EXT4 partition should be larger than 2 GB, but if I use

***** MB FAT32/4096 MB EXT 4 I get error

could not detect filesystem for /dev/block/mmcblk0p2, assuming f2s2

mount: failed to mount /dev/block/mmcblk0p2 at /data: Invalid argument
[Xperia Arc Android Development] paulholland:
The 2 GB for the size of the second partition is just a recommendation. It may be larger - mine is 8GB.

As everything worked fine with the 2 GB class 4 (512 MB FAT 32, 1430 MB EXT4) and you are sure it´s not a problem of the 32GB sdcard itself, the problem seems to be caused by the combination of the 32GB sdcard and your phone, maybe a sdcard access issue like dirt in the connector.

Another indication for this is the fact that your device gets the boot loop if you try smaller partitions on the device.

You could try to partition and format the 32GB card with your phone using abd and see whether this can be done without problems.

There is a guide for this in the wiki.

I had the same error-message earlier, and still don't know 100% how I solved it ;) What software do you use for partitioning? I think "MiniTool partition wizard" doens't work well in this case...

Trying to update my Xperia mini pro (mango) from 20150831 to the recent 20151206 release, I get the following error while flashing:

Installation error in /sideload/package.zip (Status 0)

I downloaded the .md5sum file as well and compared the checksum with the zip, they are identical, so the file is complete. Flashing the boot.img from the zip with fastboot didn't show any error. What's wrong here?
[Xperia Arc Android Development] Superrman:
i also get error from winrar that the file is damage when im trying extract the boot.img file from there

******Never mind re-download the file , now seems okay trying flash again

i hope xposed will work in this version device still booting
[Xperia Arc Android Development] tobi24:
In your case the download simply was incomplete, but mine is complete, that's why the checksum is provided - you can check the integrity. I have no error while extracting or flashing the boot.img, I get an error during installation, although the file is complete...
[Xperia Arc Android Development] Wheeljack2k:
The installation creats some logfiles in /cache/recovery/ which you can access from within the recovery menu itself (last option "View recovery logs").

In my case I found a lot of "out of memory" messages in there.

If your case is the same, I suggest you boot your phone normally (for me the new boot.img worked fine with the old 20150830 install) and make some backups just in case.

Then grab the format_system.zip from the first post of this thread and install this before installing the new rom followed by gapps. No need to format data.

That sorted it for me. I didn't loose any settings btw.
[Xperia Arc Android Development] tobi24:
Thanks for you answer, but I don't see any "out of memory" messages there. Also could not imagine a problem like that, cause I use a 32GB card, partitioned into 5,4GB EXT4 partition (4,06GB free) and 24GB FAT32 partition (22GB free).

Here is my "last_log": http://pastebin.com/jVDT9xnV

But I also wonder, you didn't lose any data applying format_system.zip again? Neither on the EXT4 nor on the FAT32 partition?
[Xperia Arc Android Development] Wheeljack2k:
Okay, where your log says "grep: /tmp/gapps.prop: No such file or directory" mine said "cp: write error: No space left on device" several times. Your case might be a bit different than mine.

Also: yes. I didn't loose any data from my sd-card by running the system_format_tool. It just formats the internal system partition (which apparently was cluttered with stuff, since I didn't run it when I first upgraded from cm11.0 to 12.1).

I'm using a 64GB SD card with 50GB FAT32 and 9.3GB ext4 for /data - but that's irrelevant when the phone's small internal memory runs out.
[Xperia Arc Android Development] tobi24:
Many thanks Wheeljack2k, because of your information that running the formating tool does not delete any data, I simply tried the same, I flashed System-Formating-Tool_signed.zip again. Now I was also able to flash the December release without the error!

Maybe this should be corrected in the step by step installation guide on the 1st page? I did follow the steps exactly when installing CM 12.1 (20150831) the 1st time, including step 4 "Format /system using System-Formating-Tool_signed.zip". The manual says "step 4 not needed when updating" - but running System-Formating-Tool_signed.zip again IS NEEDED! At least for my device, the Xperia mini pro (mango).
