[knzo]

do games run better with this rom?

Well, it should.

hello!I can't partition sd because in the revocery mode a message says:Error: run sdparted from adb! Do you know why??

There seems to be a problem when flipping the screen in the main apps screen. It trashes the icons but it gets fixed then touching the screen. Anyone have this problem?

Edit: reboot fixed the problem.

Edit2: it started happening again. Maybe Launcher Pro bug ? Anyone?

Feedback: working nicely untill now. So far so good - the best ROM yet

Thanks.

Regarding the icons, my LP behaves properly but I think I have seen that happening with someone else. Dunno, usually everyone has the flipping disabled

I tried to play some avi files with the built in video player but all failed. With default ROM every avi i tried worked. Any issues with the built in video player?

Nice job, but I can't delete any of preinstalled app's due to..err.. something.
Seams like the app folder is locked, so nor the manual delition nor the T.B. uninstall option can help.
The one which works through an exploit do not help either.

Try doubletwist.

TB has to uninstall any app you want.
Make sure it's rooted and try to click "problems?" to download another bb version.

Well... I tried Rock Player lets say and it worked in software mode, but failed with hw acceleration. That means that hw acceleration is disabled in this ROM?

Edit: I meant hw acceleration on videos.

 

[dosiara]

It worked. Thank you.

Well, here's one more ROM for you guys: Megatron.
Why the name? Seemed only logical considering the name of our device, Optimus One (Prime, cough).

It's basically a ROM tweaked for performance while retaining a decent battery usage. Also, with this ROM, you won't need to flash any other tweaks.
I daresay it's so far the speediest ROM for LG P500.

Features:

• root + superuser + busybox
• APKs deodexed + zipaligned + png-optimized
• apps2sd + dalvik2sd [1]

• performance tweaks: (JIT, hardware acceleration, etc) [2]

• includes drellisdee's custom kernel [3]
• kernel repacked to set onboot the scheduler to interactive (tweak)

• applications removed: App Advisor, Layar, Twitter, Facebook, LG Home, Think Office, Update notifications and Twitter [4]
• applications changed: Genie widget (now transparent), Music (imported from CM)
• applications added: Titanium backup, File Manager (imported from CM) and the awesome LauncherPro [5]

• ringtones, notification and alarm sounds added (including iPhone ones)
• changed boot animation to a more cute one

• auto-overclock to 728Mhz and possibility to easily revert (minitron tweak) [6]

Requirements:

In order to flash this ROM, you'll need on your device:

1. Having read the feature list and notes above
2. Root (check thread)
3. Drellisdee's custom recovery (check thread)
4. Class 4 SDcard or higher (bench it with h2testw)
5. Megatron (download it here)

How to flash:

First, reboot into recovery via 3-button-combo, ADB, terminal, w/e.

1. Partition SDcard (swap: 0, ext: 512), ext2-ext3, then ext3-ext4 it.
2. Wipe data (data,cache,dalvik-cache,ext).
3. Connect the device to PC, copy Megatron over to the SDcard, disconnect.
4. Flash it via "flash zip from sdcard"
5. Reboot
6. Read important notes below

That's it.

Important notes:

* There were some reports on other ROMs that battery usage was very high, especially on standby. While this ROM should perform better, it won't still have as good battery usage as stock ROM mainly due to the scaling governor being set to interactive. Also because of this reason, benchmarks could be slightly lower. I however promise that the overall experience and snappiness will be quite satisfying.

* I've made an easy and friendly way to decrease the clock back to stock 600Mhz. Instead of needing to use SetCPU, you just need to create a folder in your SDcard called "minitron" (without the ""), then reboot your phone. Your clock will be now back to 600Mhz. If you wish to revert it to the default 728Mhz, just delete the folder and reboot your phone again. Since the voltage is the same for both clocks, battery consumption should be around the same too. If for some odd reason, you get a boot loop, it means your phone doesn't support (*gasp*) a 728Mhz clock. To avoid a boot loop, go back to the custom recovery, toggle sdcard-pc connection and create the "minitron" (without the "") folder. Reboot, should be fine.

* Remember, you won't need to flash anything else. Everything's here.

As you already know, I cannot be held responsible for any damage you may cause to your phone by following these instructions. Every step taken is of your entire responsability.

Testimonials:

* "I noticed that the phone was another! much better performance! I did all the tests and there are no problems!"

* "This Rom is just... Amazing!!!"

* "Feedback: working nicely untill now. So far so good - the best ROM yet"

Time to see for yourself.
Just remember, it's still an experimental ROM.

Great work , phone is workin faster and booting 2times better now great work.

One Question how did u change the bootlogo ?

a2sd not workin

Hi. For some weird reason I still don't know, apps2sd refuses to work on my setup. I have tried AmberHome and this time, Megatron. Speed is amazing, but again, apps2sd is not working. I was using 1GB before for the sd partition. For the sake of following directions, I used 512MB, converted to ext4, then wiped everything. I flashed the rom and it happily booted. But it seems that the apps installed are still going to the internal memory. I mounted the sdcard on a Linux system and found out that the sd partition only has a lost+found folder. I am not sure which part I got it wrong. I am using an 8GB card. Any suggestions?

same problem here, but i didn't bothered asking this question.

 

[bioan]

Can you add an option on this ROM ? I would really like the softkeys hardkeys to be always on.

Congratulations for your work !

Weird; try changing the SDcard to test if he's the one giving you trouble.
(Did you skip the step ext2-ext3 before ext3-ext4?)

"adb shell ls /system/sd/" should return: dalvik-cache, app, app-private, lost+found (sometimes)
but more importantly, "adb shell ls -l /data/" should return the 3 symlinks.

Thanks. Regarding the boot animation, just download one (make sure the resolution is right, google here in xda) and put it in /system/media/.

How to create an ext4 partition?Can i directly create an ext4 partition ??

 

[johnqevil]

Yes, I know, but that wasn't my question. I understand that the processor in the O1 is MSM7627 and the Optimus T has a MSM7227. Since the kernel was made for the O1 would I need to find a different compatible kernel for this rom on the Optimus T or would this OC'd kernel work? I'm willing to test it, but I just wanted an opinion before I started.

Well, the AmberHome ROM runs on the T with no issues. Was going to try this one on mine later today or tomorrow. If someone else doesn't beat me to the punch, I'll post the results afterwards.

You have to use recovery to do it.
Remember you will loose all data in the SD.
Make a backup first!


Cheers

 

[juven]

Zecanilis when i try to partition from recovery i have an error that says to partition from adb!Do you know why??

 

[Tantin]

Checking out your Rom right now. So far I can say it is arguably fast. Phone is super snappy and responsive. We'll see about the battery life and how stable that thing runs.
OC: Are the 728MHz based on your own testing?

Many thanks for the good work!

PS: I like that boot logo.
