Root Optimus M recovery

[lexbot]

Hello everyone.

I followed the instructions here to temporarily root and remove the MetroPCS apps from my phone, but I got too greedy and removed some LG apps too.

Now my phone gets stuck booting on the Android screen.

The "LG Support Tool" scans my phone in the recovery process and then reports "UPDATE NOT REQUIRED"

Since their support tool thinks the phone is up to date, is there any way for me to recover the phone?

Thanks in advance for any help offered.

the answer is in ur lg booklet explains how to factory restore your phone

 

[lexbot]

My booklet has 2 solutions:

The first involves going into settings menu so this won't work for me.

The second solution is to press and hold home+lock+volume and release when the LG logo is shown.

When I do this, a droid pops up for a second near a box with an arrow coming out of it and a progress bar. Then the LG logo comes back and the phone boots.

Sort of. I have the menu bar at the top, but that is literally all. The screen is black, and none of the buttons on the phone do anything. No icons on the screen anywhere.

Any help from here??

Thanks again!!

sorry i figured that would work

 

[therooferking]

that is supposed to put your phone back to a full factory reset

 

[therooferking]

try taking the battery out after you factory reset then boot again

 

[lexbot]

It sticks on the Android logo still on a normal boot, even after taking the battery out.

The really odd thing is that while booted in recovery mode, I received an MMS message. So I tried calling the phone and I was able to answer the call. After that though, I couldn't return to the (empty) home screen.

Looks like there is no way for me to get to the settings menu.

I also get this error message when I boot in recovery:

"The application setup wizard (process com.android.setupwizard) has stopped unexpectedly. Please try again"

I recall deleting some app with a name like setup wizard. So anybody trying to clean out MetroPCS crap watch out for that one haha.

sorry im new to android dont really know much

I tried following the directions here to see if there was any chance I could trigger a factory reset in hyperterminal:
Help! My LG Optimus GT540 is stuck at the Android screen. [RESOLVED] - Android @ MoDaCo


I connect to the device ok and get "OK" back from the AT command.

However, "AT&FRST" just returns with "ERROR"

 

[lexbot]

More output from the Diagnostic tab from the modem device in device manager. I feel like there is probably an AT command to reset this thing, I just need to know what it is:


ATQ0V1E0 - OK
AT+GMM - LG-MS690
AT+FCLASS=? - 0,2.0
AT#CLS=? - COMMAND NOT SUPPORTED
AT+GCI? - COMMAND NOT SUPPORTED
AT+GCI=? - COMMAND NOT SUPPORTED
ATI1 - Manufacturer: LG Electronics
Model: LG-MS690
Revision: MS690ZV3 1 [Oct 23 2010 22:27:57]
ESN: 0x80DBDA3F
+GCAP: +CIS707-A, CIS-856, CIS-856-A, +MS, +ES, +DS, +FCLASS

Made a slight typo above, I used a "%" not an "&" with the AT command as indicated by those instructions. Still no dice.

Anyway, hopefully my local dealer will swap me out a new one today!

Ok first, the app I removed was LG Home, don't do that =)

Next, the factory reset *was* working, it just wasn't fixing my problem. All the reset does it seems is wipe the data folder, nothing more.

Restoring the home app fixed the phone. Case closed.

DAMN!! i wish i had seen this a few days ago, i know how to fix your phone.

But for anyone else...

1. Take out the battery!! And leave it out!!
2. Open the LG Update Tool software.
3. Click "Customer Support" >> "Recovery Phone"
4. Select the model number LGMS690, look under the battery and type in the serial number.
5. It Will open a new window, and search for the phone.
6. Replace battery and turn it on.
7. Connect the USB (with it on) and click "Retry" to search for the phone.

This should reinstall a FRESH flash for the phone and return it to OEM.

This will not work if you can not get USB connection to the phone at all.

 

[lexbot]

oh man that really works? Good to know.

I tried the LG tool without step #6-#7. It found the phone just fine, but reported that it was "up to date" and wouldn't do anything else.

Just for curiosity I did all the steps and the software still saying: Cell Up to Date and do nothing.

do you have a source link for this information?
(as in... Where does one get the "LG Update Tool Software"?)

I ask because I'm trying to collect information in an effort to compile all the good stuff for the Optimus M line, so that it can be revamped on this site...

many thanks!

My SDCARD got borked this afternoon, and by an hour ago my phone was a complete brick! I just used the tool found here: LG Software Updater Application Download to get things back to where they were in late December when I bought the phone! Guess I should be grateful it's working again...

THANK YOU FOR THIS THREAD!!!

[Edit] Rats. The recovery tool installed 2.2.1 ...

If your phone shipped with 2.2, you can use the downgrade method with LGNPST. Any time you use the LG Updater, you're going to get 2.2.1 because that's what the server delivers now.

 

[new optimus]

I am very new here but if your phone is not working and the software says your phone is up to date you could use the downgrade method, then use the software updater.
when I was rooting my phone I tried downgrading it to 2.2 first, I however just got the blank screen, so I used the update tool to get back to 2.2.1.

 

[chepo2309]

OMFG!!! Thanks so Much XBOXHACKER i followed your instruction and ma phone works thanks so much saved me some money dere

 

[alexxseven]

lol my guess is you removed the LGHome.apk
iv'e seen a lot of that on the forums, i just posted a way to get your phone working again without having to restore it lol, but it involves having to have a custom recovery :O!

http://androidforums.com/lg-optimus-m/301358-anyone-who-has-rooted-deleted-lghome-apk.html

hopefully that helps anyone else needing to get the home screen back

 

[WQuine]

This does not work. Just says phone cannot be updated. I also RTFM and could not find out how to do this under settings. My phone drops every call after trying to perform the z4 update on v2.2.1 (i didn't check before so my fault that I did not realise it only works for 2.2).

Please advise: TIA
