maybe that is not the rom issue, it might be because of system formating tool, can you upload the one you used??!
[Xperia Arc Android Development] mikeioannina:
I use the one linked in the first post. System format zip does only that: formats system partition
[Xperia Arc Android Development] Adam Hui:
Micro sd always produce compatibility issues with certain partition format.

mike of AOSP has not been active much.. are you taking over that project as well ? or is it suspended.

Edit : i did try to build it myself for Xperia Play.. but it doesn't build and give errors. :(
[Xperia Arc Android Development] MysteryIII:
I can also confirm that ext4 Partition created on PC (used MiniTool) became ext3 Partition after installing this ROM on Iyokan. Did exactly as told in in the instruction.
[Xperia Arc Android Development] mujib.sheikh11:
Sorry for picking up off topic here: But I think some really good developers are active in this thread who can definitely help me.

I am currently using kitkat 4.4.4 rom on my smultron but when I wanted to flash lollipop rom on device I got lots of problem. My device is not entering into fastboot mode after several tries and I can't flash the kernel that's why. When I try to enter fastboot mode the blue led just blinks and device start to boot into os. I have tried with three different pc with windows 7/8 even latest updated windows 10 as well,tried more than 5 original usb cables to find out the original problem. but got nothing. each time i connect the device i can't go to fastboot or flash mode even.

what can i do guys?? please please please help me guys. I am totally stucked.
[Xperia Arc Android Development] Adam Hui:
Install latest andreoxyde flashtool & select ur device, flashtool & fastboot drivers.

Flash kernel by doomlord method.

I dont know why, when i installed gapps, this rom become unresponsive and freeze.....

NB: I found how to fix unresponsive CM12 is change your batery mode to Performance ?. Bye bye unresponsive ? (+You need sd card class 6 or higher)
[Xperia Arc Android Development] saqibkhan:
ok i can also confirm that partition changes to Ext3.. I was always Ext4 .. but now when I connected my card to the pc.. it showed Ext3 !!

can anyone help me build AOSP for legacyXperia as Mike is away for sometime I believe.

Plus for Xperia play the ROM is not very stable.. Random reboots a lot !! Camera reboots the phone a lot too.. if you uninstall camera app and installe Google Camera from Playstore, that also reboots the phone a lot..

Install Jellybean camera manually from ES Explorer root .. that seems very stable..

Uninstalled CM 12.1 and back to Beta 2 of AOSP
[Xperia Arc Android Development] Superrman:
i must mount SD as Data? how i do it? just flashing the zip format file?

PS:

so far i used link 2sd (before CM12)

also its better then kitkat? ,sound? apps (3D games) and GUI? runing fast can you OC'd the CPU?
[Xperia Arc Android Development] mujib.sheikh11:
Hey,

Thanks for the suggestion. I have followed your instruction. But by using doomlord tool kit I am just stucked here for long since... no progress from here.

http://prntscr.com/8381pz

Please help :(
[Xperia Arc Android Development] Adam Hui:
I didnt suggest to use doomlord tool kit.

Just use Flashtool, u'll see fastboot mode tab for doomlord method. If u install your phone drivers properly, u'll be ok to flash kernel.

PS : there's a thank button to provide thanks for anyone helped you.

I have class 4 sd can I flash the rom?
[Xperia Arc Android Development] saqibkhan:
u can flash.. Yes possible

the Rom will work fast enough for u to use as a daily driver.. Flash and see ..
[Xperia Arc Android Development] yurasik_687:
Yes, you can flash Rom on 4 class card.

Daily use :rolleyes: - don't think so, for me, too laggy for daily use, even on 10 class SanDisk Ultra card...
[Xperia Arc Android Development] Hydrony:
I use this Rom with sandisk extreme plus. It works great,with great battery life. Before i had a transcend class 10 card, but it was not enough to give a good experience. So class 4 will never ever work as a daily driver

Same here and it is already written in the Wiki:

[Xperia Arc Android Development] mujib.sheikh11:
I did everything. But its not detecting device on flashtool. No idea whats actually wrong. I am stucked with this since around 3 months now :(

Please tell me if there is a way to flash kernel without flashtool/fastboot system. Is there a way to flash kernel from cwm recovery itself? That will be a great help. Thanks

(Sorry, I am new one kind of. Can't find the thanks button :( Where is it?)
[Xperia Arc Android Development] User_99:
You can only use flashtool for that.
[Xperia Arc Android Development] Ackroyd:
I had no problems at all but after installing windows10 my telephone is also not recognised in fastboot anymore :/
[Xperia Arc Android Development] vikusz:
I'm pretty sure you need to have driver signature enforcement disabled. Then try reinstalling the fastboot driver.
[Xperia Arc Android Development] MysteryIII:
Try to delete all your Phone/Adb/Fastboot drivers with USBDeview and reinstall them. Maybe it is a conflict with a buggy driver installation that doesn't change without deleting it first.

I have tried on 4 different pcs following your suggestions. same as before. it sucked :(
[Xperia Arc Android Development] plb-dev:
[MENTION=5873346]mujib.sheikh11[/MENTION] you have to do what [MENTION=5588219]vikusz[/MENTION] said. You have to first disable driver signature enforcement and then goto the drivers folder in flashtool directory. Open the application there and install the first three drivers. Your device will be detected after doing all these steps correctly.
[Xperia Arc Android Development] Ackroyd:
Thank you! I forgot that possibility! Problem solved now :)
[Xperia Arc Android Development] Adam Hui:
Now try "flashify" , same type app.

*] front LED holographic keyboard >> another dream in android
[Xperia Arc Android Development] Langes:
No playstore app will ever be able to flash boot.img on a 2011 Xperia. This is becasue your boot partition is locked even in recovery. You need to be in fastboot mode to flash a boot.img to a 2011 Xperia device, end of story.
[Xperia Arc Android Development] mujib.sheikh11:
I disabled driver signature long ago. Without that drivers were not even installing in windows 8/8.1. Its a known issue. Basically May be i did try all known and possible way. I have tried on different pcs with different os like win 7/8/8.1- tried different usb cables too. same problem always. The Blue LED(edited) which supposed to be fastboot mode light is just blinking for once and device booting os when I tried to connect device in fastboot mode. I think my devices usb port is somehow damaged or corrupted. It sucks, I was trying to run lollipop badly but I think it will not be possible anymore :(

---------- Post added at 03:16 PM ---------- Previous post was at 03:15 PM ----------

Right. Flashify isn't also working. Its just freezing my phone.
[Xperia Arc Android Development] plb-dev:
Did you disable driver signature enforcement via advanced reboot of your PC ? Look it up and make sure you followed all steps correctly.
[Xperia Arc Android Development] mujib.sheikh11:
Yes. I did that. No doubt about that and followed the way instructed a few moments ago even.

hi friends help me.

On my Xperia mini I have flashed in past this CM 12.1 rom successfully. It runs smooth but my partitioned sd card damaged so I flash CM 11 on new sd card without partition but it stuck on boot and restarts again and again so I restored on my old backup but same result. I tried to flash Xperia Mini original firmware but phone does not starts anyway.

on flashing BeanStalk-4.4006-20131128-smultron phone starts but "unfortunately com.process.android.phone has stopped" error stuck on phone and all apps are stopped. there isn't any app installed but apps memory used 366 mb and free only 54 mb .

how can I make apps memory free?

how to format data partition in Xperia Mini ?

I have tried with fastboot by "fastboot erase data" get error of permission denied .on "fastboot erase userdata" get done with 1430 bad block encountered and nothing was erased.

with adb "adb shell" "su" "wipe data" get error as fastboot

I don't no any other format command.

I have tried in recovery wipe data,cache,dalwik cache,system but not luck.

please help me
[Xperia Arc Android Development] Adam Hui:
Ok sorry for those suggested apps, [MENTION=4862164]Langes[/MENTION] made it clear.

But i think it's a wrong If u said fastboot mode for a green LED light, the correct one is blue when u connect ur phone at off state to computers by cable while pressing menu button.

And if u've installed flashtool, u'll need to install fasboot, flashboot & lt18i drivers manually which u'll find the correct ones at C:\Flashtool\drivers.

*] front LED holographic keyboard >> another dream in android
[Xperia Arc Android Development] mujib.sheikh11:
Ok Ok. I am sorry a bit for that mistake. I wanted to write actually blue LED, by mistake wrote Green instead. When trying to connect on fastboot mode the Blue LED is just blinking for once. And TO MAKE CLEAR, every time I tried to flash I totally removed previously installed drivers and followed the instructed way without any doubt. drivers also installed. But the same problems happening again and again since 4-5 month almost. All the time I followed the instruction from this forum line by line. After having no positive result I posted here to you guys to seek help :(
[Xperia Arc Android Development] Hydrony:
Would it have any effect, if i create an additional swap partition on my SD card? Will the kernel of this Rom make use of it, or is there a way of telling the kernel to do so?
[Xperia Arc Android Development] intruder16:
Other than probably killing your SD card, No.
[Xperia Arc Android Development] MysteryIII:
Did you try to clean your USB Port? Cleaning brushes for razors are perfect for this.

Another thing could be a small/unsuspicious slack joint. Try to fix your phone/cable during connecting, so it can't move even for a little bit.

Now I bought a Sandisk Microshdc UHS-1 Extreme Plus 16gb card.

Just did a clean install on my sk17i with cm-12.1-20150723-UNOFFICIAL-LegacyXperia-mango.zip - following the steps from the initial post of this thead.

i partitioned the 16gb as described in https://github.com/LegacyXperia/Wiki/wiki/Installing-Lollipop - i kept ext4 .

i installed the gapps from https://basketbuild.com/devs/TKruzze/5.1.x GApps Packages/MODULAR - Pico GApps.

everything runs nicely for me.

Problem while flashing the ROM

I tried to install the most recent release cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango.zip for my Sony Xperia mini pro, used PAC-ROM 4.4.4. before.

I partitioned a 8GB Micro-SD-Card with "MiniTool partition wizard", 1st partition 4 GB FAT32, 2nd partition ext4, both primary, not active. (just did temporarily set the FAT32 partition to "active" in order to copy the zip-files for flashing on to the sd-card in windows explorer, but switched it back to "not active" afterwards)

- I extracted the boot.img from cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango.zip and flashed it using fastboot.

- booted into recoverey and flashed "System-Formating-Tool_signed.zip"

- wiped data and cache

- but then while flashing cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango.zip, the following messages are displayed:

could not detect filesystem for /dev/block/mmcblk0p2, assuming f2fs

mount: failed to mount /dev/block/mmcblk0p2 at /data: Block device required

unmount of /data failed: no such volume

If I reboot the system now, it gets stucked just showing the boot-animation (waited for 1 hour, then removed the battery).

Since I thought there's a problem with the ext4 partition, I used a GParted linux live-system and formatted the sd-card again, 4 GB FAT32 and the rest ext4. But the result is the same, showing the same error-messages while flashing the ROM.

Hope somebody can give me an advice how to resolve this.
[Xperia Arc Android Development] Adam Hui:
Feel free to try full wipe include dalvik > format /system, /data & /data/media, continue to run the system_format.zip > flash rom.

[Xperia Arc Android Development] L3RAT:
Guys, I have some crazy idea, so correct me if I'm wrong.

Android UI is set to produce 60fps, so every time processor can not prepare frame in 16ms, we experience a lag in interface.

1) Can we change it to 30fps and 32ms per frame? (this should be fluid enough and decrease load of processor)

2) Which CPU or GPU is responsible for drawing UI and can we manage it on deaper level than ticking one of the options in Developers settings?
[Xperia Arc Android Development] tobi24:
The Cyanogen Recovery that comes with cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango.zip only shows me "Wipe data/factory reset" and "Wipe cache partition", tried both before and after flashing the System-Formating-Tool and the ROM, same result (error). There is no special entry for

dalvik

cache anymore. I also miss backup and restore options that I had before with ClockworkMod, the Cyanogen Recovery seems to be much more minimalistic...
[Xperia Arc Android Development] tobi24:
Really need help here, no idea what else to do. This is what I tried in the meanwhile:

- I went back to 4.1.B.0.587 stock ROM, because this is the 1st requirement listed on the 1st page > worked flawless

- I installed CM 11.0 (cm-11-20150830-UNOFFICIAL-LegacyXperia-mango.zip) following the instructions in this thread: http://xdaforums.com/showthread.php?t=2545367 > worked flawless

- Now tried cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango.zip again - since this still didn't work also tried cm-12.1-20150723-UNOFFICIAL-LegacyXperia-mango.zip because fred0r successfully installed it on the same device, but both just did show the error-messages again that I wrote in red color in the quote.
[Xperia Arc Android Development] fred0r:
Try installing just the Kernel from cm-11-20150811-UNOFFICIAL-LegacyXperia-mango.zip - its using another Recovery.

Then:

Then flash the cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango.zip and install as you already did (kernel, formatting tool,etc..)

You should also doublecheck that you really have a ext4-formated sda2.
[Xperia Arc Android Development] tobi24:
Thanks for your suggestion fred0r, I tried it exactly this way now, but still the same error.

2nd partition is ext4, 100% sure. However I only could use "MiniTool partition wizard" the 1st time, once there is this ext4 partition, this tool only shows the FAT32 partition on my WIN7. I have to boot into a GParted linux live-system if I want to partition or format the whole sd-card again.

[IMG="This is how I partitioned my microSD card"]http://i.imgur.com/xKKm1IR.jpg[/IMG]

After using GParted, I have to go back to Windows in order to copy the ZIP-files onto the FAT32 partition. Can this step corrupt something on ext4 partition maybe? I have no idea how else to copy the ZIP-files onto the card, I'm not familiar with linux...
[Xperia Arc Android Development] fred0r:
No - that should make no difference.

I did all the partition with the "MiniTool partition wizard" on windows and it took ages to format the ext4.

Strange - for me it works.
[Xperia Arc Android Development] tobi24:
Problem while flashing the ROM - "solved"

Final update from me regarding my "could not detect filesystem for /dev/block/mmcblk0p2, assuming f2fs" / "failed to mount" error:

There definitely was a problem with the ext4 partition, problem is "solved" now - but I can't reconstruct to 100% how... Having those error-messages while flashing, I again removed the sd-card and booted into the GParted linux live-system ( "MiniTool partition wizard" never showed me the 2nd partition or allowed me to re-partition the whole card, once I closed the programm), the only difference this time: I did insert the sd-card into the card-reader of my notebook AFTER the linux system booted, before I always had the card inserted already while booting. This way GParted showed me the first partition (FAT32) with an error, the 2nd (that has been ext4) as "not allocated". So I re-created the ext4 partition again (like I did several times before), but did not touch the FAT32 partition, that still holds the ZIP-files. NOW finally the flashing of cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango.zip succeeded!

I still don't really understand what caused the problem, if it was Windows that damaged the ext4 partition while copying the ZIP-files on the FAT32 partition or if it is my card-reader and if you insert the card after booting or before... But finally it works!

[Xperia Arc Android Development] Crim Soukyuu:
Is there still no way to backup/restore using recovery on this version?
[Xperia Arc Android Development] mikeioannina:
There is, adb backup
[Xperia Arc Android Development] Crim Soukyuu:
Is this equivalent to nandroid backup? Because only a complete image of each partition allows me to restore e.g. LINE without it complaining I'm logging in from a new device.

I've tried the newest build and it seems to run somewhat snappier than the June build I tried before. One thing I'm missing is the ability to overclock the CPU without using a separate app. Also, using a separate app it seems I'm limited to 1.4GHz - would it be possible to increase that to 1.6GHz? I've been running that on 4.4.4 and it's been very stable on that frequency.

[Xperia Arc Android Development] iamthex:
(I don't want to go off topic here, so if my short explanation is not enough, I think we should move to Q&A.) As far as I know, in case you want to OC your kernel you must build your own with the specific changes. That's what I'm doing after every release.

Basic steps:

1. Follow this to download repos: http://xdaforums.com/xperia-mini/general/guide-2011-how-to-build-cyanogenmod-12-0-t3041214

2. Edit the necessary file as seen here: http://review.msm7x30.org/#/c/270/2/arch/arm/mach-msm/acpuclock-7x30.c

3. Finally, build the kernel and flash it.

The new CPU frequencies should be available on kernel adiutor.

Please, do some research before posting, it's not so complicated. Sorry for my English and press thanks if I helped you somehow.

Simply just using latest mardon's cm12.1 kernel.

*] front LED holographic keyboard >> another dream in android
[Xperia Arc Android Development] tobi24:
Is anybody else getting random reboots with the latest release? (for me it's cm-12.1-20150831-UNOFFICIAL-LegacyXperia-mango.zip)

The ROM runs great in general, very smooth and with low battery consumption - but from time to time the screen freezes and after approx. 10 seconds my device automatically reboots. I have my phone in flight-mode most of the time, and it happens mostly after de-activating flight-mode and doing something with the phone, regardless if it's starting dolphin browser or just going into the android settings menu. One time it also rebooted while in flight-mode, but not using the phone at all (screen was off).

This is my last_kmsg.log: http://pastebin.com/yHLtScpt

Please let my know if you need something else (I'm not experienced in bug-reporting yet and not even sure if it really is one, or just my device).

Edit 1: I'll test it on another sd-card, used a SanDisk Ultra class 10 card, performance was good, but maybe it has some kind of error, that would be the only explanation I have right now...

Edit 2: I'm using a Transcend microSD card now and have no reboots at all anymore. Very strange, I tested the SanDisk card with several programs like H2testw, HD_Speed and Check Flash - no errors found! Nevertheless this SanDisk card seems to have caused problems...

[Xperia Arc Android Development] L3RAT:
You need 2 partitions on sd card: 1st with FAT32 and 2nd with ext4/f2fs or it won't work. I'm not sure, but someone had ask about formatting 2gb sdcard before and he was advised to allocate 512mb with FAT32 and 1,5gb with ext4 or something near that.
