Well, I have tried to flash my phone with cm7 for the last 3 days and when I go to reboot recovery it freezes at the LG screen and I am forced to pull my battery possibly bricking my phone. Does anyone, I mean anyone have a safe sure way to flash my phone? And I have no pc access.....srry

You need a computer. Either you didn't install recovery right. Or you're too impatient. Sometimes it hangs for a minute or so.

use terminal emulator and reflash your recovery with flash_image. you got a bad flash or a bad download of the recovery it sounds like.
there is a slim chance you aren't rooted correctly too, in which case it won't let you flash the recovery until you get permanent root. hopefully this isn't the case.
Pretty dumb question what's flash image n just incase how do I check. For a permanent root?

My advice is not to do ANYTHING until you are at a computer and have at least a half an hour available. This sounds like your first time flashing a ROM, take some time to look up key terms and such, your patience will reward you greatly. It is difficult to flash without a computer. Go to a friends house, a library, something and do it from there. To check if you have root, download the app root checker from the market. Then, after confirming root status, work from there and flash a new recovery by pushing it through ADB. Then, place the ROM on the sd card and flash it through your recovery, then Google Apps. If you follow everything I say, and it still doesn't work, come back to this thread or send me a PM and we will go from there. Look into guides before posting, not trying to be mean, but they are there for a reason.
(sorry to the other thread owner as I didn't realize I was in the i9300 forum when I posted my reply asking for similar help)
*** this is a repost from the post I made on androidcentral, with a suggestion made by dmmarck over there ***
Ok, yes it seems I made a mistake and I'm new to this, so apologies. But I tried going in and changing build.prop (specifically ro.camera.sound.forced=0 to get the camera to go quiet when the phone was set to silent) and when I rewrote the file into the system, I ended up with a phone that won't go past the 'Samsung Galaxy SIII' screen into the Sprint boot. I searched around and found that my SBF might be trashed, but at this point I'm unsure as to how to get it reloaded properly.
I am able to get into the recovery (up volume, home button, power button), and may have made a further mistake by formatting the /system. Unfortunately, I didn't make a backup using that utility until AFTER the build.prop problem, so even though I tried to recover using the recovery I made (after the problem), it is understandably not working.
Am I totally screwed or is there a way to get me back? Any help is greatly appreciated.
// dmmarck and paul627g over on androidcentral think if I can get a good samaritan to help me by posting a nandroid backup of their stock L710 setup, I should be able to recover without issues, would anyone here be able to help me?

Yes! Thank you for pointing me there, I found that a little bit ago and tried it a couple of times, unfortunately, the bootloader doesn't seem to be broken, so this didn't help me.
I really wish Samsung had the OEM ROM out!
Just found this!! Someone please tell me this will fix things?? And how do I use the file? (am downloading it now, slow download)

hey now, I appreciate what it takes to get to a fix, but I am in a bit of a pickle with this being my only phone and I am new to Android, so what may be a fix is still an exciting bit of news.
I appreciate that this is not the same as an OEM ROM now (with help from here and from android central), so I'm learning. I also understand that this is a problem that I caused by not doing my basic backups as I would any other software work, so please don't misunderstand and think that I am not understanding of what the timeline realistically will be to get to a fix.
Can't you edit the prop build on your recovery and flash it back?

quite possibly, but the recovery was made from the messed up/non-working version, so I'm not sure if that works or not... any thoughts?
I have a solution for you. Ask someone who has a GS3 to make a nandroid, copy it to your sd card and flash it. Viola you should have everything back to normal.
*warning*
Some might deny your request because certain personal information being stored in a nandroid such as gmail accounts, contacts,passwords, ect.

Yes! Thanks! This is the route that we're moving forward on in the androidcentral forums. We're thinking a FACTORY RESET/CACHE/DALVIK WIPE usin CWM will help to remove personal info as best as possible for any kind soul who does this.
I'm pretty sure someone will help you. I would have if i had a gs3(waiting for local stores to get them). I hope everything go well for you.
Come to think of it, couldn't you just factory reset your phone and it will be stock again?

thanks! actually, I have no way to factory reset unfortunately...
By going into stock recovery mode you can factory reset it. It's the same steps to get into CWM.
And if all else fail, root your phone using the odin method by getting into download mode, you'll have CWM recovery and you can factory reset using that.

hmm, I think I'm missing something because I don't have the factory recovery now that CWM is installed (or am I incorrect here?). And I'm not sure if I can get back to the factory reset options now in the state that I'm in.
As far as the odin method, I am already rooted, I'm not sure how I can use CWM recovery to factory reset at that point..
Apologies again as I am new to android and trying to learn! I appreciate you're help!
Yes, you don't have stock recovery because you're rooted. And if you're able to get into CWM you should be able to get your phone back to normal.
In CWM there's a option to wipe data(factory reset), but wiping data to cure your problem is experimental meaning idk what might happen when/if you do.

How about unrooting ?
Using this method

then going to stock recovery.
Before doing any of this first try using the nandroid somebody might provide for you.

I would think so.
Hello, I was wondering if anyone knew a method to unroot the phone. You see, I rooted it thinking I would probably use it for a while. However.....turns out it has a hardware defect. While discharging, the phone will randomly shut off during long periods of inactivity.
So I need to turn it in to LG for warranty repair. But I've already factory reset the phone and SuperSU is still there. I've tried using the built-in removal for SuperSU and it's still there. I've tried using Root & Restore, it cannot find the device, so it's still there.
Anyone know a method to remove it before I turn it in? Or would it be ok to turn it in with SuperSU installed/disabled?

I would send as is. It will be reflashed anyway. Rooting doesn't affect hardware.
Did you use this method to root? Because you you should be able to unroot it as well.

Tried, no luck. Though it probably doesn't help that I had some odd problems while rooting.....yet it still worked. I forget what exactly happened though.
1) Backup all apps and data in LG PC Suite.
2) Format internal memory from CWM. Hard Reset the Phone and Flash any latest official KDZ.
And you are back to fresh factory stock.
3) Restore apps and data with LG PC Suite if you wish.

When you flash unrooted KDZ, it wipes out recovery (cwm) with no trace. At least this happens on our P765 , P760.

So i finally unlocked my bootloader on my p769. After i unlocked it i went to recovery and restored my backup to a 20F T-mobile P769 rom (yes i know this was stupid, I should have installed recovery via fastboot while I had it open). My touch screen is borked and I have no recovery set up.
Things I've tried:
To turn on USB debugging, the backup i restored does not have a homescreen so I cannot access the settings to turn it on.
The KDZ offline flash method, but it always stops at 15% even though i've uninstalled and reinstalled the drivers countless times.
"Upgrade recovery" via the LG software tool. It gets to the part where it downloads the file and even after 2 hours it doesn't download. My hosts file did not have LGs IP when i tried this.
Is there something I'm doing wrong? Is there a button combination to force my phone to go to fastboot mode? Or can i got from s/w upgrade mode to fastboot mode? This is really frustrating.
Alright so i managed to turn USB debugging on, but i have no root or recovery. Is there anything I can do from here?
EDIT: managed to get root and installed busybox the correct busybox. i can't seem to get the recovery to install though (im using the l9 recovery installer APK. It says the recovery is installed but it won't reboot into recovery and the LEDs dont flash when i power on the phone). My phones touchscreen is still borked.
That LG software tool never worked for me and I never used it. Find a kdz uploaded and keep the phone on. No sw mode. I've been reading a lot of stuff on here about u boot and adb. . .never did any of that with other phones but I haven't bricked this one either to test any methods. I'm rambling. . .let need know what happens.

Even if your bootloader is unlocked you still have to install a ROM that is made for your phone. Just go to backup/restore then restore from sd and pick your backup. Good luck!
