[Optimus One, P500, V Q&A, Help & Troubleshooting] GameX2:
Hey XDA ! =D

I'm still interested in installing Cyanogenmod 10 on my LG Optimus One P500h, but I want to make sure I follow the steps properly first - this is my first time installing a custom ROM, and when I heard it was possible to install Android 4.0 on the P500h, I performed a backup from ROM Manager, and I "bricked" my device a few days ago. XD

I wouldn't want this to happen again, but at least, I must say I have more experience now, and learned a lesson.

Did many searches on how to install CWM with Cyanogenmod 10, I found many different ways to do it, and I'm still unsure of which procedure follow.

Read the FAQ and that was really helpful.

I will list the procedure that I would normally try - please correct me if I forget anything:

0. Root the device

Done that already. I'm on Android 2.3. When I flashed the KDZ on my LG (and so to my surprise, got me updated from 2.2 to 2.3.3) , I've used V20A_00.KDZ, so I *assume* this is the second baseband.

1. Compact/Trim Cyanogenmod ROM

Downloaded CM10 here. This look correct: http://xdaforums.com/showthread.php?t=1811325

January 8: Build 7/Final

I chose C10 over C11 because more things are compatible I believe - was it Bluetooth that did not worked under C11, but does on C10 ?

Anyways, that solve a known problem: many users said they loose network after the ROM installation. Shinobisoft confirmed it was because of the lack of space on the System partition, right ? Compacting the ROM would also fix problems for installing Link2SD ?

I've downloaded the tool "OOne ROM Editor" and opened it - it doesn't look complicated at all. What apps are safe to delete ? Will converting them to "user app" save space for system apps (I'm not sure - Where are the apps stored when defined as "User"? SD card rather than /System ?) ? Can I delete fonts without problems (I don't see why I can't keep ONLY 3-4 fonts, not 10) ? Then how much space will be left on the device ?

Read I cannot delete LatinIME.apk. Is this the default keyboard? 20MB is huge, there's no way to compact this file, right ?

Assuming there's like 10MB free, network will work, but I will have no choice but to use Link2SD to install apps fully on SD card, is this correct ?

2. Baseband stuff

Ehm, what are we referring to as "baseband" in first place?

Allright, this should make this a lot easier - as I said, I originally was on Android 2.2, when I bricked the phone, I flashed "V20A_00" throught KDZ Updated, then I rebooted as 2.3.3, so I shouldn't do anything, right ?

In "About Phone", it's listed "Software Version: LG-P500h-v20a".

3. Install ClockworkMod Recovery

This look like the tricky part.

A lot of people on other sites said to use ROM Manager...

I don't trust the use of ROM Manager anymore on my device, and I'm not comfortable with using it again. I actually wonder: When I press VolumeUp-Home-Power, the phone perform a factory reset (Many people asked already why. This apparently mean that CWM is not installed).

But is it really installed? ROM Manager actually says: "Actual Recovery: ClockworkMod Recover 5.0.2.0". What? Am I supposed to press VolumeUp-Home-Power to verify, only to do another factory reset?

So what would the non-ROM-Manager method be ? I found this one here:

http://xdaforums.com/showthread.php?t=1146566

I know about the Android Terminal Emulator already, and as a Linux user on PC, the commands "su", "cat", "chmod", "mount" are not unknow to me. I should be able to do this... That's not risky ?

So when CWM will be installed, I should be able to boot in it using "VolumeUp-Home-Power"; in theory, this is a bootloader, so if the ROM get screwed up, I *should* be able to access the bootloader to restore the ROM (I compare this to a PC BIOS - the OS is screwed, but BIOS remain accesible) ?

How could I explain that when I bricked my device with ROM Manager, I couldn't perform a factory reset, and only had access to Emergency Mode (I assume there is not such thing as a "Recovery Mode" on a P500h stock, new/untouched. The equivalent immediatly perform a factory reset) ?

By default, the LG P500h recovery partition perform an immediate factory reset - CWM will be installed here, so I should be able to access it if the ROM freak out. But why couldn't I access the factory reset, when I bricked the device? That's what I wonder.

4. Access CWM and do a Nandroid Backup to SD Card

I will now have the files boot, cache, data, recovery and system, as well as"nandroid.md5" on SD card.

5. Wipe everything, clean SD Card

6. Partition SD card (?)

Is this at that point that I should do it, in CWM ? Or wait until I access Cyanogenmod and use a software on PC to partition ?

Assuming I don't partition, I guess I definitely will lack space for applications (Due to the space of Android 4.0) ?

I will do "Partition SD Card>EXT4 1024MB>Swap:64MB. Is this correct?

7. Install Cyanogenmod

Install ZIP from SD Card, choose the CM ZIP;

8. Install Google Apps

Once the install is done, I won't reboot and immediately install Google Apps, with "Install ZIP from SD card". I chose this package (Working on JellyBean):

Then I should reboot in CyanogenMod and finally install Link2SD, I believe.

..Did I forgot anything ? :p

I *believe* that makes sense, but this is my first time installing a ROM - I doesn't look *that* hard, I did researches, but things can go wrong... :/

What should I do if I screw things up? Use KDZ Updater again ?

I'm still a little worried about that baseband thing, and the lost network connection.

Thanks for the input, cheers! :D
