Phone specs: Model: LG Optimus One P500h Carrier: Telus (Canada) Android version: 2.2 Kernel version: 2.6.32.9 Build number: FRF91 Software version: LG-P500h-V10g Background: I bought this phone (brand new) in late November 2010. Within a week or two the phone started randomly powering itself off (even when the battery has plenty of charge left and the phone is just sitting on my desk).
I hadn't performed any modifications at all (no rooting, no custom ROMs). Hadn't even downloaded any apps by that point. I have never seen it happen.
I'll use the phone like normal, the screen saver blacks out the screen like normal, and then I go to use the phone some time later (a few minutes, an hour, etc.) and I find that the phone has powered off on its own. It happens when I have the phone sitting on my desk, so the power button is not being pressed accidentally. The frequency is intermittent: sometimes it will go for a few days with no shutdowns and then sometimes it will happen twice in one day. At first I thought it was a battery problem (I thought maybe the battery was overheating and the phone was shutting off to cool down) so I went to Telus and they gave me a new battery. I tried that for a week but the problem persisted. So I took it back to the Telus outlet again and they sent it away to an LG-authorized service center for repair.
LG Optimus 2X is the first dual-core smartphone to hit in the market and the third phone in the LG Optimus-Android series. It is with 1GHz dual-core Nvidia Tegra 2 processor, 4-inch TFT capacitive touchscreen, 16M colours at 480×800 pixels. Lg optimus v software update process! Click optimus v product page from the faq page and then click software update (vm670zv9) under resources on the optimus v. If your company has deployed the LG Optimus V, the time will come to update from its standard Android 2.0 operating system to the latest version of Android. An update is available from Virgin.
Doing this cost me $30 for shipping + service charges because I didn't purchase an extended warranty and I was 1 week past the 30 day device exchange period. When I received my phone back (the service bill said that a 'software upgrade' had been performed) the problem still continues! The phone has been shutting down at random exactly the way it did before it was sent away for service. I didn't want to send the phone away for service again so I tried updating the phone's software myself - hoping this would stop the random shutdowns. I downloaded & installed the proper USB drivers using the LG Mobile Support Tool (I needed to put the phone in USB debugging mode in order for the mobile support tool to detect the phone). Everything was going fine, the LG Update Software downloaded the 100mb firmware update file (I think V10s) and proceeded with the install but somewhere near the beginning of the install the phone went into Emergency Mode and stayed stuck there.
I left it alone for 30-45 minutes just in case this was part of the install but after the program stopped responding I figured this wasn't normal. So I unhooked everything and took the battery out hoping it would reset itself but every time I would power the phone on it would bring up the LG screen then proceed to a bright yellow screen with the text 'Emergency Mode!!'
I tried a few methods to get the phone out of emergency mode (hard reset/factory reset, leaving the unit off for extended periods of time, trying the mobile support tool again, etc.) but nothing worked. The only way I was able to get the phone operational again was to download the original firmware (V10g), install the MS XML sp3 parser and run the KDZ software updater (with phonemode 'EMERGENCY' selected). So with the phone running like normal again I figured I would try the update again. Now when I connect the phone and run the LG Mobile Support Tool it says a new software update is available but then when I click on 'Start Updating' it goes through it's initial checks then says that this model cannot be updated, and it won't even attempt to download the new firmware update.
I have found the V10s available here: But I am hesitant to try and install it with the KDZ updater in case something goes wrong. My questions: 1. Is anyone aware of a fix for the random shutdown problem? I read through this thread but I didn't see any concrete solutions.
Do you think the V10s software version will fix the random shutdowns? Can you think of anything that I'm doing wrong?
Why won't the LG Updater let me install the update now?
First, a disclaimer: don't do this. No, seriously, it could brick your phone and cause small puppies in Siam to suffocate for no apparent reason. Also, this guide is designed for the LG Optimus V and, therefore, some of the links are specific to that model (i.e., the 'recovery stuff'); however, the principles are the same for most phones. This covers the rooting of the phone, not the installation of ROMs. Perhaps that will come later. Download the Android SDK (fastboot from the HTC Developer Center ((to find the file, just scroll down the page to it), and recovery stuff (mQtNjg0M2I3MGRkNmVh&sort=name&layout=list&num=50).
Unzip/unpack all the assorted things you just downloaded. Enter the 'tools' directory in your unpacked Android SDK and run 'android.' Once the 'Android SDK and AVD Manager' loads, you need to install the 'Android SDK Platform-tools' package under 'Available packages.'
Close-out the Manager, copy the fastboot file and the boot.img, recovery.img, and system.img files from the recovery stuff zip file into the 'platform-tools' directory in the Android SDK directory you previously unpacked. Connect your Android phone to your computer, head to Settings Applications Development, and turn-on 'USB Debugging.'
In the terminal, cd into your previously unpacked Android SDK directory and into the 'platform-tools' directory. Become a superuser (sudo su) and enter './adb root'. That will start the ADB tool in root (really important and, I know, pretty obvious). If all went well, nothing should really happen; enter './adb devices', which should list a device connected, your phone.
Now it's time to reboot your phone into the bootloader with './adb reboot bootloader'. At this point, you may notice your phone's screen go blue; don't worry, that's actually what it should do.
Once in bootloader, you can flash your device with the recovery files: fastboot erase system fastboot erase boot fastboot erase recovery fastboot erase userdata fastboot flash recovery recovery.img fastboot flash boot boot.img fastboot flash system system.img fastboot reboot If all went well, you've rooted your Android without any icky Windows touching. I rooted my Android phones multiple times using Mac OS X and Ubuntu. Never Windows.
I don't think you need Windows to root. To root you actually don't need Windows, OS X or even a Linux based distro.you only need the xScope Browser installed on your phone I have rooted two Nexus Ones, one last year using Super One-Click and one earlier this week using GingerBreak It honestly is not as difficult as everyone appears to make it out to be but with that said you should only proceed if you know what your doing and make backups before proceeding. The best forums for anything Android is XDA, this is well known in Android Dev circles. If you are on Android 2.3.3 follow the instructions using GingerBreak found on the XDA forums here (Here is what I did: - Make sure USB debugging is enabled -Check - Make sure you have an SD card (formatted and) inserted -SD Card inserted when I received new Nexus One from BrightStar (Android Dev.
Supplier) - Get the APK on the phone somehow, and install it - installed xScope browser, navigated to this thread (downloaded v1.10, opened it - Open the APK, press the root button -pressed 'root' - Wait a few minutes. If there are no problems, the device will reboot -device rebooted and rooted - Make sure the Superuser app is install and working -installed Superuser, ROM Manager (Premium) and Titanium Backup - Optional: Uninstall GingerBreak, you don't need it on your phone anymore -uninstalled GingerBreak - installed CyanogenMod 7 Nightly N1I have since installed CyanogenMod 7.0.1.2 N1, on both the brand new Nexus one and the one I rooted last year.

I can assure you can't permaroot a MyTouch 4G with just xScope. In the linked XDA forum thread there is discussion of what works and what does not work with this exploit.before anybody makes the jump to root do your research thoroughly. I will highlight and re-quote what I said above: Do your research and I suggest referring to the XDA forums for more in depth support.and more in-depth research There are many different Android models that just any 'one' solution will not work for all devices, this I trust is understood clearly without having to be restated. Also please note there is a new version of GingerBreak: GingerBreak-v1.20.apk (295.2 KB) (http://goo.gl/hQscM).
Thanks for this step-by-step. In my Googling, I added a couple other steps like adding new rules file for udev and adding adb and fastboot to my PATH file. My first question is related to steps 10 and 11. Once I boot into the bootloader, adb and fastboot seem to lose track of my Optimus V. Typing commands 'adb devices' and 'fastboot devices' return no devices. Fastboot doesn't return anything, actually. Which leads to my second question: What exactly is happening to the phone through the fastboot commands?
Are the fastboot commands simply rooting the Optimus V, or is fastboot flashing a rooted OS onto the Optimus V? Is there a difference? Thanks again. Thanks for this step-by-step.
In my Googling, I added a couple other steps like adding new rules file for udev and adding adb and fastboot to my PATH file. Good optional steps. I just didn't include them because, well, I consider them optional; however, they can be helpful down the road. My first question is related to steps 10 and 11.

That is strange and did not happen to me. Is there anything printing to the screen? Which leads to my second question: What exactly is happening to the phone through the fastboot commands? Are the fastboot commands simply rooting the Optimus V, or is fastboot flashing a rooted OS onto the Optimus V? Is there a difference? Thanks again.
AFAIK, the fastboot commands are replacing the necessary root files with those needed to root it. If anyone lurking has a better explanation, please give it because I am not an expert!:-). Does this interfere at all with the phone's service? Not at all; in fact, my reception is better running the IHO rom.
Do note, however, I think this voids the phone's warranty. Sorry to ask the noob question here. I just want to make sure this wont lead to a hell of a headache on the phone with Virgin Mobile's tech support trying to re-activate my phone. This is where you should ask those questions! If you root your phone, I'm pretty sure VM will tell you to go pound sand, but there are dozens of threads about putting-back the stock rom with which the Optimus V comes instaled. I just want to delete the perma-installed crap (twitdroid comes to mind) that they've put on my phone. One of the deciding factors for me to root and flash a different rom.
That and the ability to overclock the processor and get quite snappier program response. Thanks for the great directions otherwise though! You're welcome. Thanks for the kudos!
Ok,so when I try to start ADB it informs me that I don't have enough permissions on the device. Try running.adb usb and then.adb root.
