Root LG Optimus M 2.2.1 Rooted!

edodonnell · Jan 25, 2011

If you have 2.2 rooted and custom recovery installed, then you can use this rom. It is not signed, so you will have to disable signature verification.
update.zip

If you already have 2.2.1 then you will have to use LGNPST. Read this thread if you are not familiar with the process:
LGNPST Lab 1.2 (Better than my fix)

Download this zip and extract it on your pc.
MS690ZV4-root.zip (coming soon)

Flash the update to your phone following andyo70's instructions, but use MS690ZV_26-root.BIN in place of the TOT file. After the update is finished you will need to copy su and busybox to /data/local/bin/ on your phone and install Superuser.apk. Then reboot and you should be rooted.

2.2.1-system.tar.gz
boot.img
recovery.img

Hmmmmm...nice, kinda. 2.2.1 was laggy though but if a proper nandroid ump can be made then an OC kernel, stagefright enabler and custom rom can be worked on and perhaps smooth it out a bit.

Now does this mean everyone's gonna dump the work they've already started on 2.2? Hope not.

I am not recommending that everyone upgrade their phones to 2.2.1. It is probably easier to just keep 2.2.

This is useful for development purposes. We will probably be able to root 2.3 the same way, if we ever get it from LG.

Seeing as Metro seems to have choosen the Samsung Forte over any LG model for their very first 4G android enabled phone I'd suspect no 2.3 from LG.

I know one thing though. I'm not shelling out the close to $400 they're going to be asking for the Forte when it's released. I'll just stick with my Optimus. That is unless Metro has some sort of rewards program for being a customer already. Like for instance. My girlfriend has been on Sprint forever. She recently upgraded from one of those shitty push-to-talk phones, the i710 or whatever it was, to a LG Rumor Touch. $279 phone, probably more when she actually got it, but she got it for nothing for being a customer for so long.

Any custom roms that anyone has been working on with 2.2 can now easily be updated to 2.2.1. I don't know whether there is any advantage to doing that, but at least now we have that option.

This is why I asked for it to be opened!

LG was pressured into promising 2.3 for Optimus. It's on record. Question is when will it arrive.

LG to Update Optimus Line to Android 2.3 Gingerbread

posted Dec 9, 2010, 4:15 PM by Eric M. Zeman

LG today issued a statement to clarify its position regarding Android 2.3 Gingerbread. In a message posted to its U.S. web site, LG said, "LG will upgrade all Optimus One smartphones currently using the Froyo OS to the next version of the Android OS, Gingerbread. Details of the upgrade schedule will be announced locally in due course." Each of the major network operators in the U.S. offers an LG Optimus variant. LG made the distinction after a post to its Facebook page confused readers about its intent to update the Optimus devices.

so how do I get this on my phone? I mean unless there's a modified BIN or TOT file I can flash with LGNPST or it's zipped up to be installed through custom recovery how would one do this?

I added an update.zip that you can install through recovery.

Thanks for the attempt Ed but that's no bueno.

Outputs the following error:

"assert failed: write_raw_image("/tmp/boot.img", "boot") E:Error in /sdcard/edsupdate.zip (Status 7) Installation Aborted."

I'm sorry it didn't work for you. I just downloaded the zip and flashed it to my phone again and everything is working. Maybe the file was corrupted somewhere on your end. You could check the md5sum. If that matches then I don't know what to tell you.

So this allows 2.2.1 to have root privileges?

andyo70 · Jan 31, 2011

Downloaded again and md5sum matches.

I'll try to flash it again.

Nope. Same error. My phone officially hates any attempts to have 2.2.1 rooted on it.

I have 2 questions:

1- which method did you use to root.
2- Do you have any screenshoots?

thanks.

nomorefear · Feb 4, 2011

UPDATE- I do have 2.2.1 ROOTED as well.... Unless this guy made a rom that spoofs that I would say this is the real deal. Turn off verification and pooof- NO error message. I am indeed rooted and it does say 2.2.1
I will take a webcam pic and upload it to prove 2.2.1 and then root. No games people, no games!

I have to nuke my phone because I keep getting a low memory error and also the phone lost root till I rebooted so I am gonna take a crack at this and see if it might work even though andyo70 has confirmed it wotn work. Its just to put the nail in the coffin I suppose so we can get over this nonsense

What do you mean "downloaded the zip and flashed it" - how do you do it (step-by-step)?

asadullah · Feb 7, 2011

For all you people trying to figure out how to root your phone. Please read the threads in the optimus v section there are detailed guides on this matter.

I have preinstalled 2.2.1 & phone is unrooted. How do you run recovery to install .zip?

Can't you have to downgrade to 2.2 but it seems that with changes to the phone that might not be possible for now. I would wait for further testing as this problem is just now arising.

t3084 · Feb 8, 2011

Hi there, my first post....

...so in order to flash a 2.2.1 with this... so that we can ROOT the phone.... we need to be able to root the phone first to install custom recovery???

or is this for people who previously had a rooted 2.2 and THEN upgraded?

I've tried the other methods of downgrading my 2.2.1 and no matter what I try i always end up with a black screen, metro boot sound, and sometimes the sound of my usb connection.... nothing else.

I have to use the phone with without root.... AND IT'S TEARING ME APART!

Update had Success But i Don`t know how to copy the files to the place where you specified. Also do you the code to reprogram??
Because lost programming after update

edodonnell · Feb 8, 2011

If you have adb then you can use this command:

Code:

adb push su /data/local/tmp/
adb push busybox /data/local/tmp/

If you don't have adb then you can put su and busybox in the root of your sdcard, go to the market and download terminal emulator from jackpal, open it and use these commands:

Code:

cat /sdcard/su > /data/local/tmp/su
cat /sdcard/busybox > /data/local/tmp/busybox

joneidy · Feb 8, 2011

Rom works very well, Only problem right now is that somehow the phone does a factory reset and the PRL goes away (doesn`t get service) I try to get it back but I don`t exactly how. By the way is using the rom with 2.2.1 already installed. If anyone knows how to fix this will be awesome all most of us could get a rooted phone with 2.2.1.

Thanks in advance

Same here, after LGNPST update is finished (BIN: MS690ZV4_26-root.BIN, SCR: MS690ZV3_36.scr, PRL: MPC_AWS_3014.prl) phone is no longer connecting to the network - "Mobile network not available".

I tried re-update (LGMobile update makes it work) few times but it doesn't help. What can be done to make phone connect to network?

p.s. after update I was able copy su and busybox to /data/local/bin/ and install superuser.apk.

Root LG Optimus M 2.2.1 Rooted!
