Data-safe Disaster Recovery via NVFlash

OK so on Sunday whilst pissing about, I flashed a broken recovery to my phone. This resulted in a near brick, the phone wouldn't boot at all, and wouldn't even enter Smartflash. I didn't have a recent backup, so needless to say I was pissed.
However, this presented me with a challenge, could I recover my phone without losing anything? Turns out the answer was yes
I was able to NVFlash (battery out, hold both vol keys and plug in USB) over a good recovery, and the phone booted straight to it, from there I restored the old boot.img that I had, rebooted and held my breath.
Success! OK, so wifi didn't work due to the old kernel, but whatever, quick CM reflash fixed that (in hindsight, I could probably have just done that straight away anyway).
I created a little batch menu system to handle the command and let you pick from an internal or external recovery (depending on what you normally use) and a couple scripts for Linux users. Hopefully anyone that has bust their phone to the point of NVFlashing will be able to do this instead and keep all their stuff

Downloading and keeping in my O2X stash of files. Just in case of emergency. Thank you!

Great job!

Nice work. Thanks Rusty!

Great job man
Congratulations...

You can flash entire partitions with the nvflash download command.. There's even a guide to flash clockwork recovery using it on the G2x forums.. I assume you'd just change the 5 to a 7 to compensate for the different partition layouts but don't quote me on it.

Yeah you don't wanna be quoted on that, you change 5 to 14
It's the same thing, only it's never been mentioned for O2X before, clearly useful though.

@Rusty , Great Job , thanks

Seriously? It's a batch file? Double-click it and press 1,2 or X

If I go in "Device Management", under "Controller USB" I see "LGE Mobile Composite USB Device" correctly installed. I tried to uninstall it and reinstall it with your drivers but the installation fails.
How I can install your drivers?
Many thanks..

Sounds like you're not in APX mode to me, there should be nothing showing on the phone when you plug it in, completely black screen?

No, the screen shows the same screen you see when you make a flash with smartflash. In fact smartflash working properly!

Smartflash will work, because you're on the Smartflash screen. You have to hold both vol- and vol+ while plugging in the cable.

OK..Now I hunderstand...
All works now!
Thank you very much!

No luck here. While upgrading via the LG updater, app crashed about 95% through the process. After that, nothing else appears besides the SW updating.
Now the LG updater does not work (says phone can't be upgraded) and smart flash will not start flashing.
was trying this as a last resort, but no luck either.
installed the driver provided in the zip. started the nvflash.bat, choosed 2, a few things appeared and went by until it says:
"cwm-int.img sent successfully
----------------------------------
Program will now exit
Prima qualquer tecla para continuar..."
But i can´t boot to recovery (vol- plus power on), the damned "SW updating" from smartflash appears again
Any advice?
Edit1:
In fact, the "S/W updating" appears almost as soon as i choose 2
Edit2:
Ok, after this, smartFlash worked again..

You need to hold power and vol- till you see A N D R O I D appear.

Yeah, but i never had the chance. Right after the first LG appeared, while still holding vol- and Power, the S/W updating appeared.
But managed to flash the original firmware via Smartflash, after i ran the batch file you provided.
Didn't quite understood what happened here

Don't want this use this at all. (For obvious reason), still thank so much for making this.

Phone Stuck: Weird Problem

Hello Friends,
Dont know what the hell is this, but it is totally weird.
Actually i m using NOVA Rom 3 and it was running pretty good on the device.
I m browsing the firefox and checking laptops on ebay.
all of sudden my phone hangs, i wait for few minutes but nothing happened.
I pulled off he battery and restart it, but it stuck on the booting (LG Logo) and all the buttons were flashing.
I decided to restore the backup and tried to boot it into the CWM by pressing the G key, (i always use the same method to boot in to recovery)
after many tries, i plugged it into the PC via USB and boot into the firmware upload mode (by pressing the volume up and insert the cable into USB)
i tried to flash it with the KDZ Tools, it says 100% done but i cant boot up the fone.
Please guys tell me what to do,.
And i think LG will not giving me any warranty as the phones is rooted and i was using a custom firmware
Thanks

I want to know a thing
My fon is not booting, i tried every method.
So how LG guys will know that my phone is rooted and i installed a custom firmware?
Or they just checked it after the repair and then charge me?
May be some one will solve this query..
Thanks

[Q] HELP! Phone stuck in unuseable state

Hi
I've been having problems with the HOME button on my phone. I've been running PA2.51 on it so thought it was probably the ROM. I went to flash the newer 2.99 ROM from here:
http://forum.xda-developers.com/showthread.php?t=2115167
After I followed the instructions I rebooted the phone and now I'm stuck with loads of FC! I can't even reboot into recovery or download mode because the stupid HOME button doesn't work.
I don't know what to do??
Can anyone help or advise please? I'd want to get my files off the thing if I can't save it sigh

Install Philz kernel using recovery and do a factory reset.

Stuck after data factory reset.

I'm running streak droid honeycomb. I did a factory data reset through the settings menu and the device reboooted, appeared to be resetting but no I'm stuck on a screen with the android character and a triangle with a red exclamation.
I rooted and installed this so long ago that I'm lost. I mostly mess around with my phone. Any help is appreciated. Thanks

Did you try to get into recovery after charging it? You could reflash that way or nvflash it again.
But WHY THE RUM?!!!

Follow the instructions here:
Streak 7 Flashing Guide
to get into Recovery Mode. Then select option 3; "Factory Reset (User data and Internal tablet storage".
That'll get you back to bone stock assuming all you really did was root it. Done this a bunch of times. It'll work.

I hope it's alright I jump in...as I have the same problem. Stock HoneyComb 3.2 not rooted. Would boot up fine, but was unable to get into recovery or fastboot so performed a factory reset through privacy setting and now stuck on the logo. I was (don't know now able to see connect using nvflash but unable to locate any clear instructions on how to flash a ROM (either a new one or stock). Hence the factory reset.
Any help would be greatly appreciated. Thanks...

Thanks wptski.
Using nvflash I got back to 2.2 but the problem remains that I can't boot into either stock recovery or fastboot in order to install an update.pkg.
I can connect in AXP mode but haven't found any instructions of how I can use it to perform an update or install a custom recovery. It's a problem on the tablet - all the drivers are installed on pc and I've never had any problem in the past, as long as I could get the phone into recovery or fastboot. The symptoms are soft keys light up, battery light flashes 4-5 times and then it shuts down. I can boot up normally into 2.2
I should probably find another forum for my 'new'/old problem...as I'm not stuck at Dell logo anymore :silly:

Okay, to get into the stock recovery and /or Fastboot mode you are holding the up/down volume button and the power ON button at the same time, correct? It does take a 2-3 seconds for either to come up on the screen.
You can't installing anything from APX mode or get into recovery mode from it either.

Correct re: stock recovery/fastboot - lights flash shuts down. I can get into APX mode, that's how I got 2.2 on it. I can't find instructions though on how to do anything else with APX - like get into recovery mode The link giveen provided me in another post has a prewritten batch file I used - so my thanks goes to the author.

Have you tried to NVFlash 2.2 again? From your other post, you were on 3.2 before so I'd retry the NVFlash again, at least. It seems that you got into stock recovery mode before so the buttons did work before although I have heard of them getting stuck with both ON.

Thanks so much for your help wptski!
I re -nvflash'd 2.2 with the same result....successful flash and can boot into OS. Still unable to get into stock recovery or fastboot. The buttons don't feel stuck - but? Can I use nvflash to get anything other than 2.2 on to it? This all started with wanting nothing more than a 'simple' root Since I"m broken, any chance I can use nvflash to to get TWRP and ICSB4 on it - nothing to lose at this point
Another thought: would moving to a linux machine open up more possibilities?

Here's a test to see if your buttons are stuck since you have the NVFlash drivers installed, with the S7 OFF just plug into your PC, if you hear the normal audio sound when you plug in something into your USB port, they are stuck. Not sure if it would boot normally with stuck buttons.

[Q] O2X not detectable on PC and Cannot access to Recovery mode

Hi!
My phone is no longer detectable on my PC via USB (Win7 and Linux), with adb or nvflash with vol+ + vol- or vol- + power or anything.
This problem come from the last official stock update, like what, it's crazy. And no access to hidden menu, etc.
Then, after, trying to solve this problem by applying http://forum.xda-developers.com/showthread.php?t=1981359, by using Rom Manager to replace TWRP by CWM recovery (I know, it's very bad idea...), now my phone don't want to boot in recovery mode, I probably corrupt my system.
Now I have a brick, which can boot and display "S/W Upgrade Please wait while upgrading..." with vol down, but no usb IPX mode or adb or anything (to be sure, I try with another android phone, and work perfectly).
In normal boot, I have LG logo, then rom logo (an X in color), and no change, this animation continue but no end.
I had try many usb cable, reinstall lg drivers and nvidia drivers, different pc and os...
Can we restore recovery mode with special scheme, file, on a sdcard only by boot the phone?
I'm very interested in any ideas that can unlock me.
A big thank you to the community!

Yes, this script only call nvflash with predefined parameters.
My phone is not detectable by nvflash or adb, that is why it doesn't work.

I had a weird brick with my 2x too, after flashing a wrong rom and it was not working at all
So I decided to remove the battery and use a spare one I had in my stuff, and the phone turned on, and when i turned it off again I could reuse nvflash to get back to stock
Did you try something like that, or only charrging the phone for a few hours to see if comes back ?

Remove battery.
Press and hold volume- key.
Connect USB cable.
Still press volume- key.
Release when you see screen says "S/W" download.
Insert battery back.
If it worked use smartflash to flash a rom. If the screen still black, then you should try it on another pc. There is no way to screw up the nvflash mode with a bad flash or anything. Keep in mind that keys can be unresponsive during the years. It is realy hard to set my phone to nvflash mode since my volumkeys are unresponsive. I have to press them so hard that my phone nearly break in to half.
If it still not works change usb cable. Check the device manager for devices with a ! in a yellow triangle. If you see that you have some kind of driver issues. If all of these fails to revive your phone, then your phone is dead.

unfortunately it doesn't work, try with a new pc and a new cable... no change. My usb slot in my p990 is probably dead. what is infuriating is the rest works well.

Did you use fast charge with any ROM ?
USB fast charge can damage the USB connector
Did you try using the method to check if the device connects to computer with nvflash, since it does not require battery ?
Try checking this and if the USB connection broke you can send your device to a repair shop to replace it, or even search ebay, aliexpress and etc to find spare parts, and if you do so, I recommed get an extra battery (non original batteries are cheap)
good luck

That is probably a myth.
Try to use a very short usb cable and use the ports on the backside of the pc ( not a laptop!), I always had problems with the front usb ports.

SO I really dunno what could possible made this device die
I nevr had big issues with mine like this, but the closest thing that hapenned when the device stopped working, and did not charge, was to put another battery and this helped

is someone selling this the whole USB flex hardware? I wanna buy it. I am from Philippines.
