Ran into a problem I can't seem to find a solution for my LG K7 MS330 HELP PLEASE

So I followed the steps to use the LG Flash Tool and put my phone on "Download Mode" and install the "WEB_MS33010g_00.kdz" using the Flash Tool 2014. I'm coming across an error:

"Required info cannot be found."

"Contact the system administrator"

Anyone has any idea what to do here? I've bricked my phone completely where I continue to get the "authentication failed #9 modified" loop. I've been stuck here for days and can't find anything that works online. Any help would be greatly appreciated. :)

Do you know if it's possible to recover the data after flashing a KDZ using "CSE Flash" method?

After unsuccessfully flashing Nougat (going from MM ResurrectionRom) I had to go back to stock and realized afterwards that all my data was gone. I manged to make a full image of the new data partition and tried to run file recovery software on it (photorec and foremost) but it doesn't seem to find much apart from a handful of files (about 400MB out of 23GB) and there are none of the images / videos stored previously in the DCIM folder.

Does it mean that going back to stock not only wipes the data partition but also changes the partition table making the recovery impossible? Do you have any other ideas how to recover the files? Do you know if that's even possible in such case? Many thanks.

EDIT: I just realized this may not be the best place to ask the question so I re-posted it in the help and troubleshooting section.
[G2 Android Development] Redroik:
I had the same problem. Try this.

I installed LGMobileDriver_WHQL_Ver_4.0.4 and then LGMobileSupportTool, and I used some .dll (of LGMobileSupportTool) and replaced these .dll in the folder of LGFlashTool2014.

How to get LG Flash Tool to work on Windows 10

Hi everybody. So I recently had an LG G2 brick on me and panicked when I saw the LG Flash tool failing on me and seeing no remedy on this XDA thread.

But, after some trial and error, I realized:

IT DOES WORK ON WINDOWS 10

Here's how I got it to work:

1. On the first screen of the LG flash tool, you need to select something other than CDMA if you're not using a US Verizon/Sprint version of the phone. I have a European D802 so I tried the '3GQCT' option

Then press 'normal flash' (for me it was the only option)

2. DO NOT PRESS 'Read Phone Information'... the application will crash.

Press 'START'

3. I selected 'Different Country' and 'English, then 'OK'

4. The app will do some stuff.

But then it will show 'Cannot connect to server' or something like that (can't take screenshot as phone is good)

JUST IGNORE IT!!!!!! DO NOT CLICK 'OK' on that dialog, if you click OK, that application will exit. If you let it go, the phone will download the kdz file.

5. If the download stops before it goes to 100% and successfully installs the stock LG Android OS. Try a different option in step 1 and repeat!

For me when it was going to fast (zooming to 60%) I knew it would fail. When it went slower it worked!

Hope this helps anyone looking for the solution to this problem on Windows 10!

i'm searching stock rom for my LG L70 D325 the dual but the link does not work can anyone help me with a firmware for my phone?
[G2 Android Development] roirraW "edor" ehT:
No port changing for flashing KDZs. Leave the phone connected and ignore any error dialogs - don't click any buttons in the error dialogs, just drag them out of your way if necessary. Usually within 10 minutes you'll find your device is flashed.
[G2 Android Development] Jhojz22:
same problem

my LG F400K became like that too. have you found a solution?
[G2 Android Development] mCommander:
Guys, hope someone can give a clue what what can I do. I found in the previous posts someone with the same problem as me - when the phone is in download mode it says:

"USER B100

NOT SUPPORT"

and the Flash tool says: "Upgrade stopped due to error. Try to update again follow the steps below". I've waited more than 30mins there and nothing happened.

Tried with ALL drivers that i found, tried on Win 10 and Win XP - still the same result. The device manager shows the G2 as 2 devices:

1. Modems / LGE AndroidNet USB Modem

2. Ports (COM & LPT) / LGE AndroidNet USB Serial Port.

I've bricked it when by accident clicked "Clear /System partition" in the CM Recovery and made the mistake to reboot it. Since then I cannot enter the recovery (previously used the advanced reboot option) and it's stuck on the LG logo when booted or in the download mode where it says "NOT SUPPORTED".

Thanks :)
[G2 Android Development] brainvision:
reply just for the recovery. To enter it put the device OFF and wait a minute. Press and keep pressed Power and Volume Down together, keep pressed until you see the PG logo, then briefly release buttons and press and keep pressed again together. When prompted choose YES first time and confirm YES (it's no really a factory reset, in this case, if you had stock recovery it was).

Yo should now be in recovery..
[G2 Android Development] mCommander:
Thanks, but somehow I managed to f*ck it up and it didn't want to enter into the "ease" screen.

But thanks to the amazing information in the forum I managed to get it working again. I had to disassemble it, remove the battery and shorten the capacitors (almost 20 times for all partitions) near the Toshiba processor to put it in the "Qualcomm HS-USB QDLoader 9008" mode, then using a .TOT file i had to generate the partitions and the partition.txt files and using a tool called BoardDiag 3.99c to erase it completely and write all partitions one by one again. Then I used the LG Flash Tool 2004 1.8.1.1023 (the setup version) to upload the "system" partiton (because the BoardDiag writes with about 0.4-0.5 mb/s) on the device and ONLY then it was possible to boot it into the freshly installed android. I've almost gave up :D About the BoardDiag tool - there are many versions around, but only one was working for me, it's from this post (#498 from [MENTION=6882235]alajan[/MENTION]): http://xdaforums.com/lg-g2/general/...omm-hs-usb-t2933830/post62363914#post62363914.

solution?

Hi everyone, I am experiencing the same problem!

Yesterday my phone just got stuck at LG logo. It won't enter recovery or any other mode except for the Emergency (yellow mode). Only when in Emergency mode, the PC is able to recognize the phone.

I tried flashing it with KDZ_FW_UPD tool but kept getting "wparam 100 lparam 1010" error code.

So, I decided to try the LG flash tool 2014. And everything seems fine except when I get to the "upgrading your phone" part, when I get stuck at 4%. I tried different PC's, and several difderent KDZ files.

Any ideas?

WARNING -- Device Hard Bricking Using CDMA Option!!

Although this tool has been recommended to restore an LG G Pad 7.0 (v400) back to stock, make sure that you DO NOT USE THE CDMA option [and the 'CSE Flash' upgrade]! It will interrupt the flashing process [to install a Qualcomm driver :confused:] which will HARD BRICK YOUR DEVICE!!! :mad::mad: In that state, your device won't even charge -- much less turn on!! :crying:

Initially, I followed the instructions found on the following thread:

https://xdaforums.com/android/development/stock-t3297045

However, the flashing process kept stopping [at the 49% mark]. I was able to repeat the process [with no damage], but all attempts to restore my device to stock failed. So, I found this thread, and chose to use the options here instead (foolish mistake)!! Now, my G Pad 7.0 just shows up in Windows as an Alcatel device!! :mad: It's [completely] dead -- no buttons (or button combinations) work at all!! :crying:

I hope this helps to stop others from damaging their devices like I did. :(

pls help
[G2 Android Development] Djeloan:
For me it's still working.

Just when you get some error messages or something(like connection to server failed), don't close them.

You will see it makes progress on the phone. (for me it took about 10 minutes(still don't close flash tool))

Then it should restart itself, and you still have to wait about 1-2minutes.

After that, close Flash Tool(maybe it will crash, it's ok) and phone should restart itself again, and it should boot normaly!

Also i think someone should edit OP post so everyone knows that they have to wait, instead of closing error messages!

[G2 Android Development] sdembiske:
While I don't consider LG Flash Tool 2014 to be necessarily the best or safest alternative to upgrading or downgrading stock kdz's (my reference go-to is LGUP-NEW, a generally safer method IMO), I recently ran into a situation where having LG Flash Tool 2014 in the arsenal proved invaluable. I softbricked my rooted H812 with some build.prop modifications and was unable to get the phone recognized with LGUP-NEW (yes, LG mobile drivers were installed, etc., etc), or any thing else for that matter to reinstall a stock kdz. I was almost ready to send it back to the carrier for repair but decided in a last ditch effort to give the LG Flash Tool 2014 a try and flash a known, proven stock kdz I had used a few times before with LGUP-NEW. While the phone wasn't recognized per se, it worked flawlessly to get me rolling again.

I wanted to say thanks to quangnhut123 for this valuable addition in the LG arsenal and let other members know to give it a shot when all else seems to not work, provided they have a known proven kdz on hand.

Problem with server

Greetings!

I had the same problem: in the process for flashing a LG Optimus L5 II (E450G) I received the error that the Flash Tools can't find the server, but the solution is don't disconnect or touch the mobile and the PC: be patient for 5 minutos and wait that the phone restart.

Another detail: remember to put your KDZ file in the same folder where are your LG Flash Tool 2014 executable file, this is important too...

In my case this worked and can flash the phone... I hope that you have the same luck!

I'm also trying to use LGFlashTool 2.0.1.6 but it asks for a DLL for my device and I don't have that. It's funny because every single tutorial gives a link to the same online file store and says "download the KDZ and DLL," but then there's no DLL.

I'm at the end of my rope with both of these tools and just want to roll back to 11A. Anybody have any ideas? Thanks in advance!

Used this wonderful app on my G Pro F350L/S/K a lot and unfortunately got one bootloop so far.

Now, my F350L is stuck on a bootloop and I can't seem to find a way to get out of it so I can use my phone again. My flashing stopped at about 90% as Flash Tool freezes.

I can't go to Download mode to reflash and my phone is no longer detected by my PC.

Wish there is a way out of the bootloop issue for users like me to make the Flash Tool experience a very satisfying and challenging one for LG users around the world.
