Deactivate antivirus protection on your PC. Try to download again stock ROM. Maybe the file is corrupted

Need help for SHW-M110S

Guys I am in serious trouble here.
I am familiar with the flashing procedures and done it a lot of times with diff Roms.
I tried flashing my phone with Atrix Mod. The phone was hung up in startup display for a long time so i removed the battery and tried to restart.
But the phone would not start and neither am I able to access Recovery or Download mode. The phone is not detected in Odin.
As seen in several threads/advice i tried changing cable/ using diff PC & USB Ports but nothing helped.
The Recovery key combo shows something in Korean which I cannot read. The dowlnoad mode combo shows another korean lettering.
I will attach both for the members.
Please help as to how to restore it. If I can get it detected in Odin I can get it back up & running.

This is download mode, you shoot restart your computer, remove phone's battery and flash again. open Odin before and plug your device. Window 7 or 8 is recommended.

Solved....
Guys thanks a lot for the replies and suggestions.
Finally managed to solve it.
Here is how it happened...
1. Connected phone in download mode...(not detected in Odin)
2. Went to Device manager in Control Panel.
It showed as a unknown device as serial gadget something...
3. Right Clicked on it. No driver was present. Clicked on Update Driver.
4. Windows searched on the net and installed some driver.
5. After driver installation the connected phone was showing as Samsung Modem in USB Connections.
6. And it was detected in Odin....
Rest is all history

[Update][S/W stuck rescue]Ultimate rescue guide

First of all, sorry for my bad english .
After i've spend alot of hours with flash after flash, fail after fail i found an easy way to rescue our Optimus 4x from dead.
You know what i mean when you get stucked with S/W screen, and you can't flash the device in any way. < should work for : 3GQCT : wParam = 2010, lParam = 210 >
Edit 1/4/2015. New method:
< Make a cable like this or buy a USB-Y cable, and try to flash with it >

Why? Because Optimus 4x needs more power for flash. Also, try to play with battery if you are still stucked. How?
Start to flash without battery inside, wait 5-10 seconds after flash starts, put the battery.
If you don't have luck, combine with the old one:
So, what i've done?
1. I've disassemble the phone, till the motherboard.
2. I've disconnected all the connectors, and let only the USB connected.
3. I've hold battry manualy, while start KDZ flash, and BINGO!
See attachments.
4. Hold battery till the end of the flash, and you should get the LOVELY :
Before that, the flash stop at 17 seconds (10%) and i get Error 207 or 210.
okay. i'll try this now.. as a last resort..
confused
take a look at the picture..
Mine phone was start automatically on S/W.
You can let the board and try with it connected. Should work.
well flashed with ics :laugh:
thank you dude :good:
but after i tried to flash v20c latest, it wouldn't flash.. stops at 17 seconds.. error code(207)...
LOG attached..
After a lot of tries finally managed to flash latest v20c(germany). But sadly, that didn't fix anything..

I suspect the problem comes from the sim holder or antenna(the white cable) , if you still have you phone opens then try to disconnect only one of them and flash normally.
I did have same problem with the signal and magically it's gone... but my wifi lost it MAC.... in that case I just run a script to fake one and it works
anw, I also have the 10% stuck, I used the LGFlashTool2014 (somewhere in the forum, sorry) and did a clean flash V20A with CDMA setting (???) and it passed the 10% error
FYI: link for the tool
Code:

I have the same issue, I followed this guide and all others very carefully and still no luck.
Thanks for the effort.:crying:
I've updated the guide. Try it .
New solution will work 90% of time.
i tried to follow this guide with no luck, and without the cable (not quite sure what do you mean with the cable drawing. )the flash still stops at 210. my phone only starts automatically in S/W.

You should buy a USB Y cable ( http://www.nevacell.com/nevacell/images/UTStarcom/Cable/YC150B/USB_Y_Cable.JPG ) and put one USB in wall plug charger.

at s/W update mode and b2cappsetup recognizes my p880 as lge455 and says v20c youre on the newest firmware

[STOCK][GUIDE] A3300-GV/G & A3300-HV/H Return To Factory Stock Firmware

Hello everyone,
I am back on working with Lenovo tablets again. Lots of people asking me that how to return after successful or unsuccessful attemps of installing roms especially cyanogen mod series.
If you still insist on using Android 5.1.1 you can go to my thread http://forum.xda-developers.com/showthread.php?t=3267457.
Here is how to return to stock step by step :
First of all here are the links :
A3300-GV/G : http://www.mediafire.com/download/o28ke5y92kxvhui/Stock_GV_Benzersizadam.rar
A3300-HV/H :https://www.mediafire.com/?2rivx6bkg5e4ix6
1) Extract all files to seperate folders.
2) INSTALL DRIVERS (if you didnt install before. and/or if you are using Windows lower version (lower than 8/8.1/10)
If you still need to install drivers in Windows 8/8,1/10 you need to Disable Driver Enforcement please follow this guide :
a. Go To PC Settings
b. Switch over to the “Recovery” section.
c. Then go to Advanced startup
d. You will need to click on the “Restart now” button.
e. Once your Computer has rebooted you will need to choose the Troubleshoot option.
f. Then head into Advanced options.
g. Then Startup Settings.
h. Since we are modifying boot time configuration settings, you will need to restart your computer one last time.
I. Here you will be given a list of startup settings that you can change. The one we are looking for is “Disable driver signature enforcement”. To choose the setting, you will need to press the F7 key.
3) After driver installation run Flash Tool (flash_tool.exe with green icon)
4) Choose scatter loading folder and find your "MT6582_Android_scatter.txt" file from target_bin or rom folder.
5) If you do all settings correct Flash Tool will be look like this :

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
6) Power Off your tablet.
7) Put a pin to reset hole and push only for 1-2 seconds then release it. DONT TOUCH ANY BUTTON DONT CONNECT TO PC !
8) Hit download from Flash Tool wait for loading finish.
9) THE MOST IMPORTANT STEP ! Connect your tablet to computer while you are pressing volume up button. Dont release until it starts to flash.
10) Now you can release all buttons it will flash automaticly more less 5-10 minutes. After it finish you will get a green completed circle.
11) Disconnect your tablet from PC and now power up !
12) VOILA ! Your tablet returned to factory software.
I hope it fixes people's brick problem. Tried with my A3300-H and worked perfect !
Hello devs!! Need some help.. I have a a3300GV tablet which was stuck at bootloop few months back. With some research and diu tutorials I learnt that it was bricked and I followed the DIYs and flashed the appropriate ROM using SP Flash tool. It worked and then a few weeks from now, the apps started to crash one by one and it came back to previous stage Dead and bricked.
And now when I connect it to computer via USB it detects the device as MTxxx (something similar to it, which I ignored).
Tried the same DIY of flashing again, but found no luck this time. Can someone suggest a solution for it. Plz :crying:

Hello! I found this tablet while cleaning and wanted to fix it up.
My device is the GV variant but it turns out I installed an HV ROM onto it years ago. I was wondering how to turn it back into a GV rom so that I could use the SIM function.
