Root [GUIDE] Rooting, Install Custom Recovery, Install Custom ROM CyanogenMod 7

EdAndInn · Oct 24, 2011

I take no credit for this. I just compiled the steps from various posts on this forum. Thanks to PlayfulGod for wonderful CM7 Custom ROM, getitnowmarketing for Custom Recovery and joeykrim for FlashImageGUI App.

This is what I did to install Custom Recovery and CyanogenMod Custom ROM on my LG Optimus M Android 2.2.1

Downgrade to 2.2.1 from 2.2.2:

If your phone is already running Android 2.2.1 then you do not need to this step.

If your phone is running Android 2.2.2 then you first need to downgrade to Android 2.2.1

Below is the link for the Guide - See my post (by EdAndInn) in the below link:

Nice post I would include a link to the downgrading thread as newer phones come with 2.2.2 and need to be downgraded first

EdAndInn · Oct 25, 2011

@pmb116 - Thank you very much for your suggestion. Added link for downgrading to 2.2.1 in OP.

Great post you put together! Just a suggestion but the CM7 ROMs also have the A2SD script embedded in them, so you should place those steps after the Nandroid backup and before wiping the data.

Here are the steps:

Plug phone into computer.

Go to USB-MS toggle enable it.

Back up all your sd card data to computer.

Go to USB-MS toggle disable it.

Go to partition sdcard select it.

Select partition SD.

Input desired storage space: 0 for swap, 512 (or more) for EXT2, and the rest for FAT32.

Select SD EXT2 to EXT3.

Select SD EXT3 to EXT4.

Go to USB-MS toggle enable it.

Copy your SD backup from computer back to SD card.

Go to USB-MS toggle disable it.

Unplug phone from computer.

Agreeing, great step-by-step post. Also have to add, could def have used this few months ago, so surely will help many. Thanx

jpr8 · Nov 3, 2011

Want to thank you for the tutorial. This step by step was much easier to follow for me to get recovery...I just didn't feel comfortable with the other more involved procedures I found in other posts.

With the help of this forum I have been able to root my phone and remove bloatware, manually update my prl in order to try and get better 3G coverage and now get into recovery.

I would like to attempt a custom rom and the original post of this thread seems pretty simple. I have also watched mike's video as seen HERE.

I am now hesitant after reading:

The OP and the video do not include these steps, so are they necessary or just a bit more customization?

Also could you give idiot proof description of the following:
"Input desired storage space: 0 for swap, 512 (or more) for EXT2, and the rest for FAT32.

Select SD EXT2 to EXT3.

Select SD EXT3 to EXT4."

I don't understand what values to assign or what to do after I "Select EXT2 to EXT3" AND "Select EXT3 to EXT4"

I'm sure explanations to the above questions would help myself as well as others...I am not very versed in Android so I do require very clear instructions before proceeding (I live in fear of bricking my phone).

Thanks.

Most Rom kernels don't support EXT4 partitions, most of them are up to EXT3. I think PG's CM7 is the only kernel that supports EXT4. But the last step is the same for both, just pick your EXT then hit menu button, when it installs, click the back button to get to the main menu and then click reboot.

You only need yo backup the ext if you have something like A2SD. I never back it up cause it always says mount sd ext or skipping sd ext or unable to format. so i never do it

First off great guide, I mean it awesome tutorial, I have been meaning to do this for so long but every time I wanted to tackle a guide they all just confused me greatly. People need to def. use the KISS (keep it stupid simple) format when writing these and you pulled that off greatly

Couple things though.

1.) After I flash CM7 and booted into it for the first time you said to go to the market and redownload super user and the reboot app. Well the problem for me was Market wasn't there until after I flashed the Google apps back. But then everything was fine.

2.) The reboot app isn't needed is it? Since CM7 has reboot into recovery built in when clicking power > reboot > reboot into recovery.

3.) I want to partition my SD card. Is it too late for this? Or can I do it now even though I have apps and stuff flashed. Like I don't want to lose my apps I just installed, because it took about an hour getting them all back, which leads into number 4.

4.) Does anyone know of an app that will back up all my apps (at the same time, not me clicking them one by one) for free? I would get titanium and pay for the full but Google doesn't take my Credit Union card for some reason? Which is weird since Amazon takes it, and it has a Visa... >.>

But again, thank you SO SO SOOOOO much for this guide. This has brought new life to my phone, the battery lasts through the whole day now, everything is faster, even stuff like emulators runs faster and Angry Birds. Plus the flash is pretty amazing! Awesome guide! Now if only I could get 3G coverage all the way up here in Portland, OR (moved back here from Miami) hehe.

I really cannot thank you enough!

I went through this step by step to this point. When selected the recovery option my phone went to black with the LG symbol in the center. It was like this for about 10 mins. I took the battery out and popped it back in, same thing.

The only way I can think I may have varied from the instructions above are that I put the recovery RA optm 2.2.1 GNM.img in a folder I called a in my phone and I installed FlashImageGUI from the market on my phone, rather than downloading it to my computer, copying it to my phone, and running it.

Any ideas?
