LG Flashing/Upgrading/Debranding Tutorial
 

LG has both GSM and CDMA phones. Here I'll discuss on how to Flash/Software Update/Debrand LG GSM phones. Flashing depends on Platform rather than Model, so you may notice one model uses one flasher but the next model uses another. Different models which are from same platform use same flasher. LG has several platforms like Infineon, Qualcomm, ADI, TI, MTK, SEMC etc. I'll try describe on each platform how to flash a phone. Remember that, till now Windows XP is the best performing Operating Syetem for LG flashing.

~INFINEON~

Phones based on Infineon platform are flashed with GSMulti software. GSMulti has different versions like 20, 21, 30. The last one is GSMulti V30 and it supports all infineon phones till now. Infineon phones can be flashed both in USB and UART mode. Normally USB should be used, it will flash the phone in minutes where UART will take hour(s). Sometimes when phone is dead or rebooting and can't install USB driver you need to use UART then. Some old phones support only UART.

Infineon flashing on UART
1. You need a USB to Serial Converter BOX/Cable with correct pinout of the phone.
2. Install and run GSMulti v30
3. Go to Setting(s) > Configuration, select DLL and firmware on S/W box, select UART as communication, select correct port of Box/cable, then click OK.
4. Now click START on main window, when the software says Wait Phone Connecting... connect POWERED OFF phone with battery to cable and press POWER button.

Infineon flashing on USB
1. Install GSMULti V30
2. Connect phone to usb cable without battery, Windows will ask for driver, show driver from C:\GSMULTI\UsbDrivers\INFINEON.
3. Open USBMap from C:\GSMULTI, select INFINEON and click MAPPING START, reconnect the phone to usb cable without battery. Some info will show on PORT/KEYNAME, now SAVE & EXIT.
4. Open GSMulti main software, go to Setting(s) > Configuration, select DLL and firmware on S/W box, select USB as communication then click OK. Now click START on main window, when the software says Wait Phone Connecting.. reconnect the cable. If flashing not start without battery just put the battery and slightly press power button.

Some new phones are from Infineon AGold plafrom, you need to install USB PortMapping Setup_1.7. Run USBMap_V07 from C:\GSMULTI, select INFINEON AGold Series and do mapping, rest of the procedure is same.

~Qualcomm~

Phones based on Qualcomm platform are flashed with LGMDP, LGDP1, LGDP2 etc. Several updates came for these flashers.You need the USB cable, UART flashing not supported for this platform.

Flashing with LGMDP
1. Install LGUnitedMobileDriver_S4981MAN38AP22_ML_WHQL_Ver_3. 8.1.rar, connect the phone to PC through USB cable and let the drivers to be installed.
2. Opne LGMDP soft, click on the Select Port, new window will pop up.Your phone model and firmware version will be showed up there, if the phone is supported with that LGMDP version it will be automatically ticked on the checkbox. Now click Connect.
3. A new window will pop up for firmware selection. Browse and select your firmware folder in the Select Image box, all files will be automatically selected. You can change any certain file from the browse button. If you are using a DZ firmware click DZ button on the right lower corner of the window and and select that.
4. Select data handling option:
NV Backup/Restore: NV Backup/Restore always have to be done, and it is default selected option. Backup the NV data and restore the backed up NV data automatically.
Reset database & Contents: User related data including the setting data on the EFS is reset in the handset. The contents in the handset will be erased.
Erase_EFS: The calibration data, user contents, media, and module will be erased. Only calibration data is kept when NV backup/restore is checked.
Keep All Contents: No user data will be erased.
5. Now click Start and relax.

Emergency Download Mode: Qualcomm phones support a special mode named emergency download mode. In this mode, minimum units for downloading is occured so that users can download the images again in case of emergency situation. AMSS Modem, Media and Module Images won't be flashed in this mode. You may need it when the phones not power on normally/incrorrectly flashed earlier etc.

where we can find flashfile for GSMULti...

Original source where?

Everywhere in this LG section, for example

http://forum.gsmhosting.com/vbb/f177...t-here-569844/

http://forum.gsmhosting.com/vbb/f177...-here-1035408/

http://forum.gsmhosting.com/vbb/f177...-here-1107675/

etc.

Quick question?
 

I'm doing my LG GD510, which you said is the Infineon one. What do you mean by "select DLL and firmware on S/W box"?

Where do I get these?

Thanks.

GD510 Firmware you can get here
http://forum.gsmhosting.com/vbb/f177...-here-1035408/

and DLL
GD510_090916.rar

Ok, and one more question, sorry.
The GD510 Firmware says "Eur" in it, so I'm assuming it's European. My phone is North American (Rogers) and I live in Canada, so will my SIM card still work here with the European firmware?

Sure .

this Firmwares can use z3x box

This one should be in sticky.

Nasir ahamed A great man for great help, I think he always dreaming for help other . THANK's.

Yes i am agree with Rasel Opu Boss.

and Thanks to Nasir Ahmed Boss for your Great Share.


Thanks
HOssne Mamun

NO. u can't thous file on z3x

Z3x encrypcts only QUALCOMM firmwares, others are same as original, so can be used.

u are always rocking for LG section

thanks for ur great contribution

verry good...............Thank.

~INFINEON~

Phones based on Infineon platform are flashed with GSMulti software. GSMulti has different versions like 20, 21, 30. The last one is GSMulti V30 and it supports all infineon phones till now. Infineon phones can be flashed both in USB and UART mode. Normally USB should be used, it will flash the phone in minutes where UART will take hour(s). Sometimes when phone is dead or rebooting and can't install USB driver you need to use UART then. Some old phones support only UART.

Infineon flashing on UART
1. You need a USB to Serial Converter BOX/Cable with correct pinout of the phone.
2. Install and run GSMulti v30
3. Go to Setting(s) > Configuration, select DLL and firmware on S/W box, select UART as communication, select correct port of Box/cable, then click OK.
4. Now click START on main window, when the software says Wait Phone Connecting... connect POWERED OFF phone with battery to cable and press POWER button.

Infineon flashing on USB
1. Install GSMULti V30
2. Connect phone to usb cable without battery, Windows will ask for driver, show driver from C:\GSMULTI\UsbDrivers\INFINEON.
3. Open USBMap from C:\GSMULTI, select INFINEON and click MAPPING START, reconnect the phone to usb cable without battery. Some info will show on PORT/KEYNAME, now SAVE & EXIT.
4. Open GSMulti main software, go to Setting(s) > Configuration, select DLL and firmware on S/W box, select USB as communication then click OK. Now click START on main window, when the software says Wait Phone Connecting.. reconnect the cable. If flashing not start without battery just put the battery and slightly press power button.


Hi,
Where can i find DLL & SW files ?
Thanks in advance for your help

100% work tested me km900

@habib76

Lot of firmwares and dll's are shared by our members, just look around this LG section, there is a search option for you. Moreover, if you need other what you can't find, ask here, I'll try to upload.

nasir bhai, u r the best

need vedio tutorial,if possible,please upload.
i'm new in gsm line

any type/format

need gd350 dll
Thank u

Following the the tutorial on how to flash the LG Phone with the GSMulti v3.0

1. Install GSMulti, Install The Infinion USB driver, also install the TI_Neptune driver too.
2. Copy the firmware folder to the GSMulti folder on c:, read also the pdf file from the GSMulti, read it start from 128..
3. Restart your computer
4. Take the battery out of your phone plug your usb cable into your phone but not the computer
5. Run USBMap_V01, select Infinion at the top of program window, press mapping start, plug the usb cable into your computer, when usbmap finds your phone press save & exit.
6. Unplug the usb cable from computer.
7. Run GSMulti, go into configuration and select the Dll file and FLS files that are in the folder and select USB in port information and select ok
8. Press Start and then connect the USB cable to the computer, flashing should now start. If flashing works, you should then use the LGUtils as normal to upgrade to a better firmware as this is an old firmware but its the only one to be found that works with GSMulti but at least it gets your phone working again.

I haven't it and also don't know other what model's .dll can work or not
U have to wait for thread starter :D

Gs500v
 

should i use GSMULTI 3.0 for it?

Yes .

Hi,

I had never done earlier LG Flashing, want to learn ...... which is the best box or software to do it and how......?

About flashing, almost all LG phones can be flashed with original free software, you can get a some how to's on the first page. For original firmware and DLL search this LG sub-forum. Moreover, you need some help can ask here, I'll try my best to share.

About unlocking, you need one/two current professional tool (professionals mus have more than one) which are offering latest models, cause normally you'll get latest phones for unlock in your shop. You can flash/repair also with these tools.

...so I have downloaded BIN_GT400AT-00-V10i-EUR-XX-OCT-05-2010+0.zip and I have LGDP2, so all I need now is GT400 DLL

Anybody here have it?

Gs500v startup hang
 

my gs500v went hang on startup. how to i fix it sir? i tried flashing it but canot open port. and cant detect it. need your help pls.! :confused::confused:

Use Windows XP, and step by step follow Infineon flashing procedure.

NO. u can't thous file on z3x

Now I have everything to falsh my GT400, BUT I must be doing something wrong!

I get to the part with COM1 UsbAddr, it gives some numbers
I add all ssw and gdf files

...and than nothing!
I tried starting than inserting cable + vol.up and i tried inserting cable + vol.up than starting... nothing.
Phone just goes charging battery after 4-5 seconds, even though it is full, any suggestions, what am I doing wrong here?

EDIT: NVM, it just started working when I used LGDP2_V36_UMTS instead of LGDP2_V34_UMTS_KF750

Hi,
Download this LGDP2 V35, extract and paste the exe file to C:\DOWNLOAD and try with it.
LGDP2_V35_UMTS.rar
Let us know what happens.

Ok.
Since flashing worked with LGDP2_36 (using it right now to post this), I will try little experiment...

When I come home, I will download LGDP2_35 that you provided, LG GT405 firmware that you posted and try to flash LG GT400 with it! Just for fun!

Do you have DLL for GT405 or I can use GT400 DLL?

ps: firmware that you provided for GT400 works great, thanks again! ...question, why don't you pack dll with firmware?

Well done!!!
GT405 DLL
GT405_100427_MP

will try to pack together on next uploads.

Thank You!

Flashed it with files you provided, works great, gt405 firmware works on gt400, no problems, fast flash, 5 minutes...

I used LGDP2 V35 for it, worked just fine, without any problems.

...now to look for some other firmware to test it with...

What about KM570 or to go wild and try with GT540???

KU990 looks good too... will test that one too.

Can you provide DLL files, sorry to bother you, I feel experimental with this phone.
