Root LG Optimus M Hard Reset Didn't Work

[ThrowBack 330]

Hey AndroidForums users I'm new to this posting threads stuff but I have an LG Optimus M Android Phone and it was on 2.2.1 when I rooted it using gingerbreak , I installed an application called SystemApp Remover which can remove bloatware , while I was happily removing system apps I came across something called "setup" or something of that nature my phone rebooted itself automatically and when I unlocked my phone I get a black screen but a working notification bar . I tried taking out battery several times with no luck , so I had to hard reset it when I got this error "the application setup wizard (process com.android.setupwizard) has stopped unexpectedly" and I'm forced to foreclose and the same thing but with a hard reset phone , a working notification bar with a black screen . That's when I realized I had stupidly removed the system setup application using SystemApp Remover -___- I don't know what to do so I created an account just to post this thread , anyone with any information to help me with my problem will be MUCH APPRECIATED and Thank You in advance !

It would be greatly appreciated if someone could help me with what to do or some good advice because I am a foster child I'm only 16 , and this phone is my only contact with my family and friends and now I'm upset with myself with making my phone a useless brick . It's not even activated I had a text app in which I could text and receive calls if I had wifi but now I'm stuck with nothing I'm pretty sure I'll get no help from any company if I call because it wasn't activated and I rooted it which would void any warranty . Again any help would be much appreciated and thanks a lot in advance !

Did you happen to install a recovery? I'm gonna take a guess at no.

Are you posting from a PC? if so you will need a usb cable,ADB, your phones usb drivers(here), and the SetupWizard.apk. (I'll PM you ADB and the setupwizard.apk)

1)Install the drivers

2)Plug in the phone

3)unzip ADB_AAPT onto the Desktop(or anywhere you want really, but for the sake of instrustions...)

4)Put SetupWizard.apk into the ADB_AAPT folder to make this easier

5)if you are using windows7or8 you can hold shift and right click on the ADB_AAPT folder and click "Open terminal here"
IF NOT, CLICK SHOW BELOW

Spoiler

press windowskey+R and type "cmd", press enter.
change the directory to the Desktop by typing

cd Desktop\ADB_AAPT

press enter.
If that doesn't work...

Spoiler

cd %HOMEPATH%\Desktop\ADB_AAPT

press enter

6)Check to see if ADB will run and find your phone

 adb devices

if it shows your device you can move on to the next step

7)mount /system as rw(Read/Write)

adb remount

8)push the setup.apk into /system/app/

adb push SetupWizard.apk /system/app/

9)reboot the phone

adb reboot

10)report back

Hey Thanks for the reply ! I did everything you mentioned in the instructions and when I reached the step where I had to input "adb devices" it would tell me "List of devices attached" but no devices listed . so I tried the next step anyways and then it showed "error: device not found" I'm currently running Windows xp 32-bit at my school but I'll try on my foster dads laptop when I get home thanks again for the reply and if it doesn't work again any further advice would be greatly appreciated !

Hey no luck again on my foster father's laptop he's running windows 7 64-bit and I tried running cmd as administrator , I think it might have to do with my phone being hard reset so it might be unrooted and usb debugging isn't enabled by default . I can't change any settings as when I unlock my phone it's just a black screen with a notification bar at the top , any suggestions ?

Send sammyz a private message. You can search for posts from him on the Optimus M All Things Root forum. He might be able to help you get back to stock.

Thanks for the reply I'll send him a pm .

you installed the drivers from the LG site? for the ms690?

here are the drivers I use. LG MS690

Hey ThrowBack 330,

I PM'd you with a link to my easy unbrick guide to returning to stock.

Once you unbrick you will not be able to root the same way you did before, but you phone will be usable until you can root with a PC.

Edit: I moved your thread since you're rooted

Sorry for being a newbie but I went to the guide and the firmware cab file link was broken so I went to the other guide and it required me to select MS690.dll after opening LGNPST . I was getting a different .dll file (LGNPST_Utility2.dll) from the program . I thought it would work anyway , I went ahead and selected the corresponding .bin file and hit start when I received an error saying "Error: Unable Loading Port Component" Any further advice ?

It worked fine for me to download the cab
I did download it just in case LG was just about to pull it though.

LGNPST is a pain to use, it would be better for me to just upload the cab so you can download it.

 

[ThrowBack 330]

I agree that would help which version of LGNPST do you use ?

2.2.3 but 1.2 and 1.3 never gave me problems.

Hey I tried everything again even with the alternative firmware and I keep getting the same error message:

Upgrade Error
WParam: 100
LParam: 84

I'm going to try the other tutorial link and if that doesn't work then idk :/

When you get that error, try this:
Unplug USB
Pull battery
Put in battery
Plug in USB
Try again.

I would try that but now whenever I try to turn the phone on it gets stuck in "S/W Upgrade Do Not Unplug Mode"

Can you PM me the ADB too. I have the usb drivers and Setup wizard.apk. All I need is the ADB.

Turn it off and back on, try again.
