Thank you for cooking the LG Expo base rom for flashing. Included MS Office is not 2010 and no threaded email. Included Windows is 6.5. 5.2.2174. Looking forward to an update with Windows 6.5.3 and Office 2010. I am a fan and contributor from your LG Incite ROMs. Thanks! Rick

Can you please reupload it?
Thanks

As I saw in oneof your other posts you are using a GM750. This isn't even the same phone as the eXpo or IQ. You're not going to be able to flash one of these roms to your phone. There are hardware differences and software differences that prevent this.

It's not impossible to flash the GM750. You need a rom that was made for that phone.

When that happens it should still go into emergency download mode even though the screen might not say it. Try it again and run the update.

help with flashing
I cannot complete the flasing process im using windows 7 an cannot get pass step 7 as windows is unable to install the drivers properly. Is there a way to manual install the drivers ? The phone will go to the emergency download screen and the comp just says "driver instalation was unsuccessful ". Looking in the device manager i can see the LG USB MODEM with the ! of a failed instal. Any help would be much appreciated.

The drivers do have their own installer, you should be able to find it in one of the sub folders of c:\users\all users\lgmobileax

thx xdapants i did find the drivers but this did not fix the issue. It seems to be a connection problem with phone and comp (a common problem it would seem) do i`ve orderd and am still waiting for a new cable and hope this is the simple fix im looking for. However, if like i suspect this still does not work can i flash from memory card ? i think this was possible with the htc kaiser (best phone ever) or if not can i flash over a bluetooth connection ?

I don't believe it's possible to flash an lg phone from the memory card, at least not at this point. And as the phone needs to be in download mode, flashing over BT wouldn't be possible.
Consider trying a different USB port; ideally on the opposite side of the computer if you haven't already.
Hopefully the replacement cable will work for you. It seems to be the phone doesn't like being used as a storage device, but that shouldn't really have any bearing the download mode connection.

Im trying to flash my IQ to the latest Dragonstorm ROM and got a error with a load of Chinese characters and something about a server error. Did i miss anything? I got it to see my device and it was put into emergency download no probs. I just a bit reluctant to not wanting to brick my phone

did you extract to the correct location?

(2) using odin version 1.84
(3) kies program is turned off (if any)
(4) make sure you are logged on as "administrator"

Load the kies so your device will be detected... you dont need to install Galaxy Y drivers because you have the Kies after Kies load you can close it..and open the Odin and prepare the Files to the Destination Box
the odin will detect your device anyway if you are willing to come at the shop ill fix your SGY

Make sure you have installed KIES
then connect your phone via USB cable to pc (MAKE sure it showed your device is installed and ready to use)
Next thing to do is.
exit KIES
meaning press CTR+DEL then go to process tab look for KIES and hit end task
exit all Active application in system tray and also Anti virus.

I'm always stuck at the boot.img or connection or NAND write. My phone doesnt show the bar showing the process completion. Stuck in custom ROMs. x(

last Q. my com have a recycle .exe if ur familiar, can this be harm my SGY,
cause it broke my SDcard,

My experience on flashing
Since now its my second time flashing an SGY , first i unbricked my classmates SGY on Android 2.3.5 (B'coz she tried flashing another custom ROM with her custom ROM(Very common sense but she still do it so she end up bricking her phone, then she ask help for me ) )
Before i flashed i charged my SGY to 100 % (Fully charged)
Then i wiped my micro USB connector with a soft cloth
Then i turned off my phone
Then i pressed Ctrl+Alt+Del(Windows task manager) then i clicked "Processes"
then i ended up the Kies and ADB Session(i don't have it with my family PC)
Then i logged off my user then i logged on my dad's user account (Since he's only the one that has the administrator priveleges)
Then i downloaded Odin v 1.85 from SGY FAQ's here
Then i downloaded Doky's DXKK4 Wipe Pack for me (Since its the factory firmware of my phone)
Then i opened up Odin
And i pressed Power+Volume up+Home(i waited for 2 seconds before i release home button)
And i pressed Volume up on my phone (ODIN MODE)
Then i started selecting the valid DXKK4 files like PDA,PHONE/MODEM File,CSC
Then after that all i pressed "Start"
Then it stucked a bit on system.img file but after that all a green "PASS"surprised me then i started to jump jump jump (becase i successed flashing my phone)
Then the last message in the message box is "Successful 1/0 Failed"
Then my phone restarts,Then after i setup the phone i setup my CSC , for me i select XTC because ,my phone is an open line then it factory resetted again , then i set it up again , Now my phone is in the DXKK4 firmware again YAY ! Refer to Doky's thread on the Development section for full instructions before flashing
Try vaccuming your USB Ports or try an earlier version of Odin for our SGY

if you're running windows 7. You can type the combo button ctrl alt del and you will see "start task manager" and click on the processes and find all programs kies named like "Kieshelper" i think there's three different kies running in the processes. End process it and find your antivirus in the processes. Example is "egui" for eset, "avg" for avg, and many more. If you cant find your antivirus, just disable it, or if it can't be disabled, just uninstall it, and reboot. After reflashing, just install it again. Please note that KIES and ANTI VIRUS must be completely closed. Make sure that you have kies installed in your computer, if an antivirus is open, there might be chance that you'll receive a fail in odin.

before flashing its either format your SD Card using your phone..
How to ? Go to Settings>SD and Phone storage>Unmount SD Card(Wait for the status on notification bar if SD is safe to remove)>Then the "Format SD Card" option will be available, Tap on that >Format SD card>Erase All
Then Your SD will be formatted, so Backup first
Before flashing perform a factory reset
How to? Go To Settings>Privacy>Factory data reset>Then it will prompt you if you want to format the SD card , Just put a check on that but don't forget to backup first>Then follow the next procedure for factory resetting then after that, Power off your phone then Press Power+Home+Volume down then a warning will appear , Press volume up to proceed to ODIN MODE then connect your phone then select the appropiate files for your phone then click "Start" then see your message box on the left bottom to see what's happening on flashing your phone

Please do check the following:1. USB Ports
Try a different port. [Applies to PREVIOUSLY DETECTED PHONE and/or NEW PHONE CONNECTED FOR THE FIRST TIME]
If you are using a desktop computer, try the USB ports at the back of your computer.
If you are using a notebook computer, make sure the power plan you're using is not in Balanced or Power Saver. Try using High Performance when trying to flash and make sure USB Selective Suspend is disabled.​2. USB Filter Driver [Applies to Windows Vista/7 Machines though later version of XP Supports USB Filter Driver]A Filter Driveris a Microsoft Windows driver that adds value to peripheral devices or supports a specialized device in the personal computer. It is a driver/program/module that is inserted into the existing driver stack to perform some specific function.
Written either by Microsoft or the vendor of the hardware, any number of filter drivers can be added to Windows. Upper level filter drivers sit above the primary driver for the device (the function driver), while lower level filter drivers sit below the function driver and above the bus driver.​Try deleting theUSB "Upper Filter" & "Lower Filter" Entry in registry editor and check if it fixes the problem.
Delete the USB Upper and Lower Filter in the Registry by following the steps by following the steps below:
Before we go any further, please first backup the Registry.
Important: This method contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry
incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can
restore the registry if a problem occurs.
For more information about how to back up and restore the registry in Windows:
http://windows.microsoft.com/en-US/windows7/Back-up-the-registry
1. Click “Start”, type “REGEDIT” (without quotation marks) in the “Search” bar and press Enter.
Note: If UAC (User Account Control) pops up, please accept it.
2. Right click “Computer” (the root node) in the left pane, click “Export” under the “File” menu, choose “All” under “Export range”, and select “Desktop”
in the “Save” in box and type backup in “File Name”. Click “Save”.
Note: The backup file is on the Desktop and named backup.reg. We can simply restore the registry by double-clicking the backup.reg file.
3. Click “Start”, type “REGEDIT” (without quotation marks) in the “Search” bar and press Enter again.
4. Locate the “UpperFilters” value under the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
5. On the “Edit” menu, click “Delete”, and then click “OK”.
6. Locate the “LowerFilters” value under the same key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
7. On the “Edit” menu, click “Delete”, and then click “OK”.
8. Quit Registry Editor and restart the computer.
Make sure you follow the steps correctly.​3. Samsung drivers[Applies to PREVIOUSLY DETECTED PHONE and/or NEW PHONE CONNECTED FOR THE FIRST TIME]
Reinstall Samsung drivers to make sure driver files are intact. Believe it or not, a simple update or program installation can mess up drivers on your computer.
Before you re-install the driver, please take note of the following:
Your phone should be disconnected and/or any USB device (USB Flash drives, cameras, ipod etc etc)
Close any program that communicates with you phone -KIES, Odin etc etc.
If you're using for more than an hour or have opened several programs, please turn of your computer and the turn it back on, a warm boot (restart) is not the best way to "refresh" your computer before you install drivers, It should be a cold boot (shutdown-power up)
If you've taken my notes in consideration, please by all means re-install the drivers ​4. Try a different version of Odin that supports Galaxy Young.
Make sure the Odin version you're using supports Galaxy Young. Some Odin versions support specific samsung phones ONLY​5. Restore your computer to a state where your phone can be detected.[Applies to PREVIOUSLY DETECTED PHONE ONLY]
This option applies if all else fail and do me a favor, don't call your computer's support team, they will make you do a bunch of troubleshooting steps and in the end, a simple restore would take care of it.​ANOTHER NOTE:
Pressing the POWER BUTTON without having both HOME BUTTON and VOLUME UP KEY pressed will not get you anywhere. Either your press HOME BUTTON first then the VOLUME UP KEY before you press the power button or you make yourself believe that your phone won't go into download mode/Odin mode. That being true, previous comment that says: "home button+power+volume down" I believe is a typo. ​Good luck to y'all who have this kind problem.

Micromax a87 [driver new solution/ device not detected and recognized solved]

MICROMAX A87 [DRIVER NEW SOLUTION/ DEVICE NOT DETECTED AND RECOGNIZED SOLVED]
HI axai here...
i bought this fone ninja 4.0 that came with a ULTRA VIBRANT 4 inch
WVGA 480x800 display that is MUCH MUCH MUCH better than the display of optimus black which claims to
"outshine the sun"
many people are facing the problem of "device not found" or "Device not recognized" while tring use their a87 with pc using techniques of sdk given on the web...
But this solution is a bit different and SURELY 100% working on windows 7
Be patient and follow... you will get it working..
many dont know but yeah...A87 has its driver "INSIDE THE PHONE" no need to install or download any crap A87.zip files!!!
steps are just a bit similar but not totally same.... so please follow carefully
steps are as follows:
[do not download any A87.zip]
1. Download jdk 32bit , Android sdk , Unlock root , adb_usb.ini ......(google it ul fine or just see old posts of rooting for links)
To create adb_usb.ini:
open notepad
paste the following lines-
# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x1c9e
and save it as type "all files" and file name "adb_usb.ini"
2. Install jdk
3. install Android sdk, after installing open sdk manager form star and select "android sdk platform-tools" and "google usb driver" unselect the rest, click install packages. After installing put the adb_usb.ini file in "C:\Users\(your PC name)\.android"
4.now uninstall the sdk only!! from add or remove programs.
5. go to "C:\Users\(your PC name)\.android" and delete all files EXCEPT 2 flders AVD and cache and the file adb_usb.ini and restart your computer.[NOTE :if you dont do this next steps wont work]
5.REMEMBER!! Switch off your internet first!!..and Now choose a rear usb port of your cpu.. for laptop any port will do. and connect the phone. you should see " installing drivers" as shown in "image1" in attachments below.
6. when youclick on the installing drivers message in task bar you can see this box pops up...if successful...the final results of the dialog will look as in the "image2" in attachments below.
7. Now in your fone u should be able to see a USB icon in status ..when you expand the status bar you will see onli "usb mass storage" option and NO debugging option.
go to ur phone settings-> applications->development and enable debugging.
8. on your computer screen you will get a dialog box saying "Common_Handset_USB_Driver" and itl look as shown in "image3" in attachments below.
9. Install that and when it says finish..see your fone screen you will get the debugging option..
CONGRATS ..this is a 101% working solution and works on XP too but windows 7 is recommended..
REMEMBER U WILL NEED TO USE THE SAME PORT EVERYTIME...if u change the poert you will have to repeat above process UNFORTUNATELY yeah.... but hey its working too.
Then proceed to root ..
you can follow this post too... to turn your a87 to a HD gaming device...

[Q] Soft bricked i9250 international

Hi and thanks for taking the time to read this
My brother tried to do the update of his nexus through the phone download (not through the sd card or connecting to a computer). Since this it will not start up and if i go to download mode it says that it is downloading constantly (have left for hours).
I can make it to the clockworkmod recovery v6.0.1.0 but unfortunately my brother didnt make a backup before trying to update to 4.2 jellybean.
The unfortunate part of this equation is that i cant access the phone via usb as the drivers wont install and the phone doesnt have an sd card slot except the sim card slot. So placing the correct files on the phone is proving too hard for me to complete.
Sorry if this situation has been covered before but i have searched for about 1.5 hours now to no avail. I would very much appreciate if someone can take me through how to get this phone working in any way possible (i dont care if he loses all data and goes back to stock).
Regards

CWM recovery offers the ADB interface. I would:
1. get the naked driver package (see Efrant's guide)
2. boot device into recovery and connect usb cable
3. open windows device manager, find your device and manually update the driver
4. use adb to backup the /sdcard to your computer
5. flash 4.2 stock images using fastboot
6. done

op, if you just want to get the device to working state again, and dont care about any data:
1. get the naked driver package (see Efrant's guide)
2. boot device into bootloader and connect usb cable
3. open windows device manager, find your device and manually update the driver
5. flash 4.2 stock images using fastboot
step 3 is the same, the same procedure, the same driver; windows is dumb so you have to tell it again when device is in bootloader (which, btw, is NOT the same as download mode).

Hi and thank you for the replies.
I have downloaded the naked driver but cant get it to work. I have followed the steps to make it work but i get to the device manager and there is no option for uninstalling current driver (as it has none currently). It only has update driver software (which if i use windows to search for it cant find any) and properties. The Galaxy Nexus icon in the device manager has the yellow exclamation mark sign on it. I can
When i try to manually find the naked driver it comes up with the following error
Windows found driver software for your device but encountered an error while attempting to install it.
Google Galaxy Nexus ADB Interface
Access Denied.
Where to from here lads, i appreciate the input

if you're using windows 7, i read something about you need to disable windows digital driver signature check, or something in those lines.
can't help any further on that subject, since i'm a Linux user (Windows knowledge is very limited) and also that is an operating system's issue and would be better discussed in a Windows forum, IMO.

Thank you for another helpful reply! Yes i am using windows 7 - i will try to perform the task now - results soon. In the meantime if anyone else knows instructions on how to do this i would love to hear

I am at work and dont have administrator settings on windows 7 so i went to an older computer and started fastboot.exe. I went to recover and there was the IP address of the computer went to that and recovered. From there i went to reboot and now i am just getting a Google in the middle of the phone (as before). I will wait some time to see if it will start up now. If not what is my plan?

So i havent got any closer to having a usable phone.
Im up to this step:
"flash 4.2 stock images using fastboot" how do i do this? i have fastboot and i have the stock image

Thanks for that i had since found that and have printed it and will work through each step methodically. I have the stock image on download.
I have spent the best part of my working day on it now. Fingers crossed it all works out.
Thanks to all who have helped me through this far
