C++ error when flashing

I tried to Flash F200L30f_00.kdz with the LG flash tool 2014 under Normal flash mode because my current ROM was same "F200L30f_00"

LG flash tool was run without asking install C++ Runtime & progress was 100%. But finally it given error massage that "C++ Runtime error"

But I have installed C++ Runtime successfully before run the LG flash tool. (downloaded from From given link & updated from 2005 to 2013)

Other problem is CSE flash option is available only for CDMA type.

In another thread I found that we should select 3GQCT instead of CDMA. But 3GQCT no option for select CSE format. (I don't idea about what type we should selected)

If C++ error was occurred no any damages happened to my phone.

I want to downgrade for F200L20f_00 firmware. But I have doubt to do CSE flash if C++ error would come again & will my current 4.4.2 OS get damaged.

Please advise me to Fresh format for vu2 F200L phone.

Thanks

Prasad

I encountered this error when my computer screen dimmed its display during flashing the kdz. No damage happened to my firmware and it was fully functional. Never had a problem since. Id say its a bug.

cant flash lgusercstool stopped working

Hello! I have tried flashing using [MENTION=2181463]quangnhut123[/MENTION]'s LG FlashTool2014 and it worked great on my lg g3 before when i rooted. Thanks quangnhut123!

So now i tried it again since i got locked out of my phone (even after the hard reset, it still shows the backup pin (which i have forgotten) and google account unlock screen -- which do not work). On the computer the lgusercstool appears after i click on cse flash. IT works fine at first but the computer stops at 99% then a popup window says lgusercstool has stopped working. Funny thing is the phone gets to 100% and reboots but it still shows the same thing -- backup pin and google account unlock screen. my phone is still unusable until now. Please help.

Stuck at 2%

When the LG Mobile Support Tool gets to "Upgrading your phone...", it gets stuck at 2% and eventually gives up and asks for Retry. The phone is still at 0%.

I have tried removing and re-installing the drivers with no luck. The CDC Serial Device fails to install, but the Android USB Modem and AndroidNet Serial port show up correctly. I have also tried both Normal and CSE method.

What can I try now? My phone is LG G2 D803.

Background:

I rooted with IOROOT. Edited build.prop but forgot to change permissions. Did a factory reset. Now no bootloader, recovery, fastboot, etc. I can get into download mode by holding the Vol+ and plugging in USB, but the tool isn't work for me.

EDIT: SOLVED using the TOT method. I think the tool stops at 2% when there is a mismatch in device/firmware. The TOT method may bypass this. Make sure to use the proper TOT and DLL when doing this.

Flashing LG G2 (D802), Stuck at Analyzing phone.

Hi!

I downloaded the LG FLASH TOOL 2014, using it right now to flash my G2 back to stock firmware. After I did everything as instructed, the process is stuck in the Analyzing phone phase, every time it stops at 60% .

It might help to mention that the problem I had in the beginning (which led me to this) is that I tried unlocking the bootloader using a tutorial on YouTube, but just after rebooting, my phone wouldn't start anymore... when I plug it into my PC, I get a bunch of local disks (empty with write-protection) Instead of internal storage.

Can anyone help, please ?!

Cloudy G3 2.2. -> Official LP kdz Italy v30a, Flashtool connection fixed

hi guys I came from Cloudy G3 2.2., but I managed to stuck in TWRP/Download mode, Flash tool could not detect my phone, after that I almost messed up my phone, I lost TWRP(dont know how :D) and I stuck in download mode(without detection-PC didnt make that beep sound when it finds new device), the trick is that you have to load KDZ from browse-folder, then you have to wait and your phone gets detected, if not, then change Port- USB LG to port41, so you choose kdz from your pc, then you gonna wait and after a while your phone screen download mode changes and you get connection on port41, then slowly hit start and start flash via flashtool, you have to be patient, I have also stuck few times at some 4% or something, I dont know how but Flashtool has some problems loading kdz bigger than 1GB, so Flash tool goes slowly...

the point is that G2 is unbrickable, I was so scared that I managed to break my G2 (cause i stuck on broken download mode- my pc didnt detect my phone), but trust me, you cant brick it!!! I will check this thread to help you, so just ask and I will answer :)

Hi bro, I have experienced this sh*t also in the past, just DO NOT format it!!, then you have to Push recovery using Linux, its somewhere on xda, you just connect your phone in linux( you need bootable USB), and then you push recovery bootloader etc., after that you can boot into recovery, and also check my last post, i experienced also some problems with flash tool, I stuck at 4%, but give it a time and it will work, just load your kdz slowly... :)

I was following the steps on my vs985 on 12B, got to the point where it goes to 100% and says the "connection error" thing. I left it going like many have said to do, but it stops at 10%. My phone in Download Mode eventually says COM3 and the bar on the screen starts to fill up. At that point the progress bar in the flash tool starts to go, too, but when it gets to 99% there is an error and my phone factory resets to 12B. Any suggestions?

Hi,

i got LG G2 D802 32GB Euro , no branding , i wan't to go stock (got Optimus G3, root, TWRP on it).

After going through 2 windows of LG FLash Tool (CSW flash) i got error " connection to server failed try again in a moment". After clicking Retry i got "S/W Update process" going to 2% and error "Upgrade stopped due to an error". On the phone still 0% and download mode.

I tried using other usb port, restarting pc, installing vcredist.exe, turning off phone and on, running in windows xp/7 mode, as an administrator, turning antivirus software off and NOTHING. Hosts files ok. Any ideas?

How to go stock if LG Flash tool fails like that? :( Win8.1
[G2 Q&A, Help & Troubleshooting] d00lz:
Have you tried using the TOT method? It's common for people to have success using the TOT method when the KDZ method fails. The TOT method can be found if you scroll down a little bit on the Return to Stock thread.

If the TOT method fails, you could try my possible fix for the LG Flash Tool getting stuck at 2% for the D802.

Flash takes how long? LG G2 Lollipop @0% for an hour

Trying to get Lollipop on my Lg G2 D802 32gb, (4.4.2 not rooted) , its been over an hour since I started the Flash Tool (CSE) with the 30a.00 kdz,.

The phone says "Firmware Update" 0%

Do I just keep waiting or try something else?

It says Do not unplug USB connection until process is complete

Also, no doubt there will be another powercut here soon, so everything will shut down. I should unplug USB before then or what?

I would definitely recommend you all choose your native language. Though of course you can leave Korean selected, I did; and then all of the status messages were a bunch of question marks. I cancelled the update accidentally because a message came up saying (later in English the second time around) 'cannot connect to server' or something. I thought it was just a 'continue' or 'failed' message. The best thing to do is leave it until the update completes, even if that message appears.

LG Flash Tool does not detect LG G2 D802

I got my LG G2 D802 stuck on lg logo screen after I tried to update it to Lollipop using the official LG update tool. I followed the steps in the original post, installed the attached drivers and everything but when I click the CSE Flash and then start, the LG Mobile Support Tool does not seem to recognize my phone and shows the error message that "The phone is disconnected from the PC".

In the Windows Device Manager, I see a node "CMCC Compatible USB Device" when I connect the phone in flash mode. And the phone is stopped at "Processing Commands" message.

If I connect the phone directly to the USB without holding the Vol-up button, the LG Mobile Support Tool detects it in that case, but then it fails at 4% while writing the image.

and btw, I am using windows 8 (64b) host.

[Xperia Z2 Tablet Q&A, Help & Troubleshooting] bleedink:
Recently rooted my device and restored OS before sending in for RMA. Somehow Sony knew that the tablet had been altered and didn't allow me to get fixed. Does anyone know the proper steps to restore to warrantable shape? Seems that dual recovery lingers after a restore. Afraid to root now and kill the warranty on my other tablet. Can anyone comment?
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] Moscow Desire:
When you say "restored os", do you mean to say you reflashed a stock ftf rom? If so, when you unlocked bootloader in the beginning, did you backup your "DMA" codes first so you could restore them later?

Flashing a stock ftf room should overwrite your custom recovery, at least my understanding anyhow.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] bleedink:
No I restored from the boot menu restore option.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] bleedink:
I backed up keys but didn't restore because of glass damage. I was under the impression doing a restore would overwrite all. Perhaps not.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] Moscow Desire:
No, you will need to re-flash stock firmware, then re-install the keys. That should take care of things.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] bleedink:
I see. So if I root and the tablet has broken glass or digitizer I'd be out of luck. At least that tells me how to do it after warranty is up. The screen has broke so many times I'm scared to void my extended warranty now. The old one is a brick now. I guess I'll have to live without. It mostly allowed me to unlock with nfc and ad block so not too much.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] Moscow Desire:
There used to be an app available, that would allow a windows GUI for devices that had broken/dead digitizers. Basically it ran via USB connection. Not sure if it would help you in this case though.

As far as returns, and a rooted tablet, this would probably depend on the service center you sent it to. Most of them will service a rooted tablet if you press the issue and argue your point. Especially seeings a cracked display has nothing to do with the root.

Hope you get it sorted.
[Xperia Z2 Tablet Q&A, Help & Troubleshooting] bleedink:
I had to buy another tab as they won't service anything that has altered software even if you want to pay. Scared me enough to not root the new one. I agree with one having nothing to do with the other but in Laredo that's how they see things. Disappointed as they seem developer friendly, until warranty that is.
