I, for one would love that. I'm trying to maintain 6 different phones, but my girlfriends gt540 is the most important one. ;-) lol

And about the battery pull in public ; that happens every day in Denmark as well. Lol
[GT540 Optimus Android Development] tejasjadhav:
1. It's like the Pagefile in Windows. It acts as virtual RAM and uses a SWAP file or SWAP partition. With SWAP you would be able to run more number of apps at a time. Swappiness is like the level of priority given to SWAP with respect to the actual RAM. Higher the Swappiness, more the system uses SWAP. If you don't have a good quality SD Card (class 6 or higher) then I recommend you to use lower Swappiness as it would slow down the whole system

2. The apps we have are in an APK format. When you open an app, the system extracts the classes.dex file into Dalvik-cache and then runs the app. If you ODEX a ROM, the classes.dex file is extracted in the form of ODEX file. It helps the system to skip the extraction step and directly use the ODEX file, and the RAM usage is reduced, giving more free RAM. But themeing is not possible in an ODEXed ROM.

3. In Gingerbread, the in-built Task Killer acts aggressive and kills background apps when it's low on RAM. Our phone already has less amount of RAM. Supercharger modifies the scripts so that it doesn't kill apps so aggressively.

4. If you're talking about CyanogenMod Apps2SD, both are almost same

5. Which other customizations??

Have you odexed framework-res.apk or systemui.apk?? Coz they may cause FCs.
[GT540 Optimus Android Development] Reptilez_DK:
I haven't experienced it in stock roms, but I usually flash my phone the day i get it. Lol :D

[GT540 Optimus Android Development] tejasjadhav:
You using Swapper 2??? If not, use it. If yes, try Swapper (just swapper not swapper2)
[GT540 Optimus Android Development] hackwerk:
Yep, same here...

And no, I haven't ODEXed anything. All customizations/optimizations I numbered in my last post are not (yet) on my phone. Just the new standard Muri4k ROM.

Guys,

how can i install the recovery.img file from zip file 2.3.4 v2.0 RC1?

and what helps;

Any link how to do that?

I dont use swapper, no need for it whit this rom.

I will make you an update.zip to make it easy for you ;)
[GT540 Optimus Android Development] m1st3r1:
look in ur system/etc/init.d with root explorer.

if there is 07swapon edit it (open in text editor, dont forget to mount rw)

change the echo 60 > /proc/sys/vm/swappiness to echo 30 (or any number of swappiness u want)

u can also change the /dev/block/mmcblkop3 to mmcblkop2 if u have fat32 n swap partition (with no ext partition).

LOL.. my friends used to ask my how to unlock my phone. let alone they dont how to turn it off.. and i found myself pulling out my battery in public transportation when my phone hang.

Hi all,

I just have a question for Joost Van Hoek.

Can you please add a changelog to your OP?

I hate to search for it everytime a new rom comes out.

@Mur4ik you should add the new music beta app instead of the old, standard one in your next release. The new one is great! And now (for me), the old only cost space
[GT540 Optimus Android Development] nibras_reeza:
Music? The Google Music? It's something like a Music Player for cloud. Google might start charging for it. The AOSP Music Player is something meant to play local files. Google Music has a different purpose.

@mur4ik and everyone else: Got any idea what is FOTAkill?
[GT540 Optimus Android Development] quasimidi:
FOTA = Firmware Over The Air

FOTAkill disables the system checking for ROM updates (as far as I know).
[GT540 Optimus Android Development] Eth4n:
Take a look at the additional battery drain :rolleyes:
[GT540 Optimus Android Development] EazyLuke:
You can simply delete the old one with Root Explorer or Titanium Backup, don't you?
[GT540 Optimus Android Development] nibras_reeza:
It can be but it seems to have been added on other CM7 builds as well. There's no reason to kill firmware updates over the air on other builds which support it.

Plus, if they wanted to kill a system component, you can simply remove the code for it rather than add more code.

[GT540 Optimus Android Development] :
Well, after smg72523889 posted later that day to say his re-flashing of the French Organge ROM fixed his call issue, I tried again.

I flashed the above ROM twice via KDZ as at first my phone was stuck in a boot loop - even after factory reset and fastboot -w. After the second flash the phone booted into 2.1.

I flashed the new CWM 4.x.x.x and then flashed Swiftdroid RC1 I now have no problems with receiving calls and the caller not being able to hear me.

I thought I would post this update a I know some other people are still having the same problem.

Many Thanks to EazyLuke, I really appreciate it. :)

Nik
[GT540 Optimus Android Development] EazyLuke:
You're welcome! And as I said, I can also upload the kdz with modified partitions if you want to have it.

Or instead of flashing kdz again, use Mur4ik's bootloader builder (Tut here: http://xdaforums.com/showthread.php?t=1171531)

Jepp, can acknowledge after testing this weekend. i received several calls and i had only one time this issue (relsolved by pressing pause & resume). Now i also have a better reception and my phone's running faster & smoother as before flashing. so i can state: i'm happy :D
[GT540 Optimus Android Development] EazyLuke:
@Mur4ik: I just saw that other phones can be undervolted with custom kernels. Would it be possible for our phones too? As far as I understand that would make the battery last longer!
[GT540 Optimus Android Development] nibras_reeza:
People having issues with GPS, install fasterfix and change the ntp server.

I was playing around with /system/etc and stumbled on to gps.conf and I opened it. Found that GPS ntp servers refer to gpsonextra.net. ping to that domain didn't complete in a reasonable time. I used fasterfix and changed to ntp.org north America server and received a reasonably quick fix although I live in south Asia.

Just curious but why does it refer to gpsonextra.net and not ntp.org?
[GT540 Optimus Android Development] nibras_reeza:
122MHz is already there.
[GT540 Optimus Android Development] effortless.:
That isn't undervolting. Undervolting is lowering the voltage of the CPU, not the clock speed.
[GT540 Optimus Android Development] nibras_reeza:
Undervolting technically reduces clock speed afaik.
[GT540 Optimus Android Development] effortless.:
Yes, but reducing clockspeed will not reduce voltage. Also, undervolting won't reduce clock speed, but the cpu may become unstable, so you would have to reduce the clock speed for stability.
[GT540 Optimus Android Development] EazyLuke:
No effortless is right, undervolting reduces the CPU voltage, I'm not talking about underclocking!

Regarding stability: You could lower the voltage just a little bit, like 0.05V or something like that, finding a good spot where the CPU is still at stock 600Mhz.

If that all is even possible :D
[GT540 Optimus Android Development] nibras_reeza:
Did a bit of Googling. I assumed mobile phones would already work on lowest possible voltage but looks like you can undervolt it as well.

Reducing clock speed does reduce voltage because each frequency band has a set voltage. Undervolting may need way too many experiments. Have you guys tried undervolting? Stable band/vsel values?

I use ondeman 122-710.
[GT540 Optimus Android Development] effortless.:
There are no voltage bands (in our case) as for us to achieve an overclock of around 900mhz that is actually stable, we would need to increase the voltage of the CPU, which we cannot do in this case. If we could set the voltage, then we would have 900MHz stable.
[GT540 Optimus Android Development] EoinSheehy:
No, not working for me. Maybe Mur4ik can shed some light on this issue?

The RC1 and (so I guess RC2 also) has swap built in. There's a file called 07swapon in system/etc/init.d. This file switches on swap. I believe the swappiness 60 is too high. Modify the swappiness in 07swapon to 10 or something and tell me the outcome.
