Yup, if you look at your wall charger that came with your S4 you will see that 2.1A is the preferred charging. I had an old charger that could not charge my GS4 in the car while I was using it. I have a couple of different high amp chargers that I use so no specific brand loyalty just don't buy the cheapest.

How big is the download from LG server; is this a full system image or just recovery?
[G Pad 8.3 General] DracoPiece:
It's about 1.4gb but you can use the flash tool instead just download the kdz then flash via flash tool

[G Pad 8.3 General] geoffreyp:
Hi, thank you for this tutorial.

I made a huge mistake flashing a 4.4.2 Kernel (http://xdaforums.com/showthread.php?t=2617476) on my stock rooted rom (I misunderstood the instruction and thought it was stock-compatible...).

Consequently, my G Pad is not able to boot anymore, even in recovery mode.

After several attempts, I succeed in putting the G Pad in download mode and I followed the procedure described in post #1. During the downloading process, I was surprised that the G Pad "reboots" periodically, by staying in download mode. This didn't bother me until the next recovery step.

Indeed, during the S/W upgrade, this reboot leads to "losts phone connection" error and recovery failure... It seems to append every 2min30s.

Do you have any idea of why it happens or what is it ? Any trick to make the G Pad stay in download mode longer ?
[G Pad 8.3 General] r3stor3:
Make sure your device is fully charged and turned off.

Simultaneously press and hold the power and volume down buttons.

When the LG logo shows up, release the power button only.

Now press and hold the power and volume up button while keeping your hold on the volume down button.

When the factory reset screen appears, release your hold on all buttons.

Press the power button to continue.

Press the power button again to confirm if you’re sure you wish to continue with the reset.

For the OP this is the true hard reset button combination!
[G Pad 8.3 General] geoffreyp:
Thank's for your advice r3stor3 ! :good:

You were right, my G Pad had indeed too low battery to recover, although it has been plugged all day to my laptop. So I charged it all night with the LG charger and tried the recovery process again in the morning (the one in OP #1, not the hard reset), and it worked !

Nonetheless, after recovery, the system display only 1% battery. But that's another story...

Have a nice day !

[Edit : Nevermind, after being fully discharged, it starts to charge again. Everything is fine now.]

[G Pad 8.3 General] rockbigdave:
Although I didn't try and flash what you did, I wasn't able to put mine into Download mode to recover it either and only received a black screen! Turned out it was just ridiculously low on charge. I knew it was 'working' because with a USB cable in to the PC and holding the power button on the tab it was making connect and disconnect noises. Your best bet is to plug it into the mains charger and hold the power and/or power + vol down (I'm not sure what worked, I did a combination) until you get an LG logo. when you get to that, let it charge fully. (You should see the battery logo on screen)

Shouldn't have a problem once it's fully charged. :)

[G Pad 8.3 General] ptargino:
Me too. No Items To Fix. :(
[G Pad 8.3 General] NYCguy2020:
Finally got this ***** back to stock :D Here's how I fixed it:

- First remove/uninstall everything (i.e. Drivers and the LG support tool). Delete the LG folder in C:\programdata

- Do a fresh install of drivers and the LG mobile support tool.

- Restart computer.

- Open the LG support tool without connecting your tablet.

- Go to Options (top right corner) and select Upgrade Recovery

- You will get a little pop up menu asking you to enter phone info.

- Put your tablet info in the menu there.. Model name: LG-V500 , and your Serial number ( found on the box)

- The tool will start searching for software and will stop at %15 asking you to connect your device (don't close that pop up) or touch anything.

- Now power off your Pad and put it in download mode (volume up and down) then connect your USB cable.

- The tool will recognize your tablet and will download/install the software...Sit back and let it do its thing.

- Once done you can do a factory reset as shown in the thread.

- Congratulations your tablet is now completely stock. :laugh::good::good:

* NOTE: this will take a long long time, so make sure your tablet is fully charged before doing this. It took me like an hour and half from start to finish and I have a very fast internet connection so be patient.

Don't forget to hit that thanks button hard :D
[G Pad 8.3 General] worldbreaker:

[G Pad 8.3 General] vimesUK:
Many thanks to the OP for the first post. My stock, but rooted with TWRP installed, went into a mode where it would only boot to recovery and nothing else. No amount of restoring a previous nandroid or installing another ROM would resolve this. It happened after I got a notice of a 117mb update and agreed for its install.

Using the LG tool I recovered the tablet and have since installed the update, as it now has the std recovery to install it.

All seems well and I'll probably remain on stock without root etc for a while.
[G Pad 8.3 General] detection:
Unfortunately this is not working for me. :(

My G Pad was stock+rooted, didn't do anything crazy with it. Yesterday I went to use it and all apps started crashing. I figured it just needed to be rebooted, so I did a normal reboot... and got stuck in a boot loop. I've been trying everything to get out of it and nothing is working.

In this case, I get the tool going and everything seems to be working, but when it hits 100%, it says the server failed. If I just keep it plugged in anyway, it seems to possibly keep going (but I dunno really) and eventually my tab shows the LG logo again... but remains in boot loop. Factory resetting still does not help.

ETA: Tried this on my boyfriend's Windows 7 laptop instead of my Windows 8 computers, and it actually went through and completed the tool properly... but still stuck in boot loop after, and again after factory reset... :(

LG Gpad stuck in download mode

Hi There,

the LG support tool said that there was an upgrade needed. So when I did this it said: "connection failed' and it aborted. After that my pad is stuck in download mode. When I try to turn it on, it goes straight to download mode. I've tried every combination with power and volume buttons. Even when I charge it, it goes straight to download mode. I guess my tablet is dead :(

I've got the same Problem.

LG V500 rooted no custom recovery installed - never flashed any custom rom.

It all started with strange app behaviour (timey - an alarm app crashed) and the system was slow. I did a reboot and am now stuck in a bootloop right after the LG logo starts to animate. it just stops the animation and restarts it.

So I put the damn thing into download mode and started the LG Mobile Support Tool and updated the software (it showed installed version is 10A and in programdata it downloaded 20D) - at about 95% it restarts and is doing the same bootloop.

After reaching 100% and getting a message "successfully updated" I disconnect it (still bootloop) and turn it off and do the factory reset. Still stuck in bootloop.

So I tried the option via flashtool 1.0.54 (up-to-date??) and KDZ_FW_UPD.exe

I copied the kdz from progdata/phone to my desktop and tried to update.

Type: 3GQCT Phone Mode: DIAG (Tablet is in download mode)

It is showing "Unpacking KDZ - KDZ file extracted - Extract file error - ===FINISHED==="

the V50020D_00.kdz is 1.22 GB

Tried also via UpTestEX.exe and the instructions posted here http://xdaforums.com/showthread.php?t=2622777 but on this point:

"- You wait a few seconds and another window will ask country and language.

- Country = Republic of Korea.

- Language = Inglés."

nothing happens. No new window just the normal LG Mobile Support Tool which is trying to update as usual. although I have chosen the kdz file it tries to download again.

I'm kind of frustrated and don't know what to do next. Does anyone know how to help me?

BTW: last chance - I'm downloading another V50020D_00.kdz file and trying it with that.

Hope anyone can help!
[G Pad 8.3 General] FrakMe:
I had the same issue this past weekend; v500 stock + root ,then random crashes and messages about sd card being removed. I rebooted the tab, which started a weekend of frustration.

The gpad got stuck in a boot loop and after numerous "successful" flashes from the LG Mobile tool and hard reset via key combo (which didn't help at all). I also tried to flash the kdz downloaded from the LG tool with "LG Flash Tool 2014". This didn't do much and gave an error (I don't remember the exact message), but it was nice enough to delete the kdz for me. I re-launched the LG Mobile Tool in order to re-download the kdz and decided to let the tool complete the flash.

To my surprise, my g pad actually booted and has been fine since. No data loss (except root), v50020d , all good.

Very weird experience, but if I had to guess, the second flash tool reset a flag somewhere.

Anyways, I hope that info helps someone so that they don't have to waste a decent amount of time attempting to fix the same thing.

tl;dr: tried a different flash tool that didn't work, then used official flash tool and it worked.
[G Pad 8.3 General] BlazinStylz:
I had a bootloop with my LG g Tab too, I used the insructions at the beginning on this thread...and it works.

It is important, to follow this step:

6. Click on "Options -> Upgrade Recovery" on the upright corner

On the right side of the window, there are two menues, click on the left of them and there you find "upgrade recovery".

My program is on german...but it sounds like the same.

I tried to use the flash tool too, but there I´ve made the same experience like "kiwiwiwi", it doesn`t work.

For Verizon owners???

The "hold both volume buttons and insert USB cable" does not appear to work on the Verizon VK810 models. Any suggestions?

LG Mobile Support Tool managed to download the 1.5GB kdz file, but then gave an error when trying to apply it. So, I have the .kdz file if there's an alternate way to get it onto the device. I tried "adb reboot recovery" and then "adb sideload", but that failed the signature check.

This is all for the purpose of doing the recovery step so I can root w/ Stump, like I did my other VK810 ...

[G Pad 8.3 General] FrakMe:
I thought I explained the process I went through pretty well. I still don't know what caused the boot loop, but the failed attempt at flashing the kdz with the tool linked in my initial post seemed to do something to help the LG Mobile Tool to do what it was supposed to.

so to sum up:

- use the LG Mobile Tool to dl the kdz

- use the linked tool to attempt to flash the kdz, following the instructions for the CSE flash in the post.

- use the LG Mobile Tool to flash the device

Beyond that, I can't help much other than "it worked for me".

Good luck.

Oh, and if this makes your gpad burst in to flames, it's on you. :)
[G Pad 8.3 General] blaze2k:
For me doesn't matter what I use to flash it goes up to 95% the tablet reboots in goes in to a loop and the LG flash tool or Lg support tool goes 96% and it crashes. and the tablet goes LG logo => sound => reboot. I wasted half a day and no luck

Thanks for this guide. I tried using this since my G Pad 8.3 V500 has been bricked... However, when the LG Mobile Support Tool starts downloading the recovery, it goes well up until 70% or so. The download then simply fails.

A little backstory, I bought my G Pad 8.3 today and wanted to root it as soon as I could. I made the mistake of doing an OTA first. Anyway, I proceeded to use Towelroot and rooted my phone. I then wanted to install twrp recovery, so I tried using flashify. When booting into recovery wasn't working, I tried doing a factory reset, and now my G Pad no longer boots. I can only seem to have it in Download Mode.
[G Pad 8.3 General] BackCheck:
I just got mine and made the same and made the same mistake. Mine did not get stuck in download mode. Make sure the USB cable is unplugged and try holding the power for 30 seconds and power it back up. Mine just boot looped. I got it out and back to 4.2.2 the following way.

I started with the 4.2.2 KDZ file here http://xdaforums.com/showpost.php?p=51468259&postcount=8

I downloaded the LG R&D Tool and the offline fix hack to get it to not run from the LG servers from links here: http://storagecow.eu/index.php?dir=Xda%2FLG+Optimus+G+Pro%2FPrograms%2F

In the offline fix there is an automated script and instructions. I initially got errors about upgrading the R&D tool, replacing the installed files with the ones from the LGMOBILEAX.zip file from the same place as the offline fix. I would direct link but I don't have enough xda posts to link to offsite. After flashing back to 4.2.2 I think I had to factory reset but it was late and I may have imagined that part.
