Yes, i`ve tried. Mine lg 32lh2000 was updated at service to 3.68, and then i downgraded to 3.15 for usb-hach, and other things. After that i upgraded from 3.15 to 3.67, 3.69, and finally 3.75 without any problems. (probably the upgrade works directly from 3.15 to 3.75, but take a look at release.cfg for the fw update files, probably you dont want miss them. I mean fw 3.63-3.67 doesnt include release.cfg, but 3.69, and 3.75 does.)

Hello everyone,
I tried new firmware 3.75 on 32LH5000 and 32LD320.
Both TV's work without any problems with this new firmware.
for 32LH5000 update was from 3.67 to 3.75
for 32LD320 update was from 3.69 to 3.75
some things that might help you
under Menu, select OPTION, like manual update from USB ( 7 times button FAV)
- restore firmware to previous version > press 7 times button 9 and TV will do the downgrade
password for Service Menu:
all versions up to 3.65 - 0000
3.66, 3.67, 3.68, 3.69, 3.75 - 0413

I tried to force downgrade 3.75 (7 times button FAV) and my tv died. no worry, RS232 restore worked like a charm. so, if you encounter any bugs in 3.75, revert to previous version (only use 7 times button 9)

Hello everyone
i have a 37lh2000 (european model) and want to upgrade the firmware from 3.12 to 3.15 to enable the USB . I have looked and can't find 3.15 firmware that i can download without page being expired. Does anyone have a working link or is there a different version i can use.
Or can this be done without upgrading the firmware on this model using a IR remote to get into that hidden menu?
Thanks in advance

Hi to everyone !
I have 42LH3000 and I have long time ago hacked USB.
I bought 32LD350 and make hack too. Menu interface on this is much better compared with my LH3000. I do not know what FW version have in both.
So, can I make FW upgrade on my LH3000 that I get same menu interface like in LD350 ?
And need I to hack USB again if I make FW upgrade ?
Thank you for all answers in advance !

Hi All,
I am owning LG 42LH50YR (Indian / Asian model ) and followed all the steps ( like copying latest European 3.67 & US 4.30 .epk files to USB/LG_DTV folder & pressing 7 (> 7 times) while highlighting options).
I got TV software update popup but none of the new firmwares are visible to upgrade.
I am having S/W version 4.04 anfd FRC Version 3.04.
Any help in this regard will be highly appreciated.

Hi Friends,
I am new to this thread. Please help me with the below queries:
1. I have LG - 26LH20R LCD TV running on Ver 4.04 (Asia). I have enabled USB with OK + Ok method. I donot have the option for DIVX and it plays only .avi files using USB. Can anybody tell me how can i play .MKV, .MP4 or other formats?
2. Is there any firmware update that can be installed? Can i try to downgrade it to ver 3.15 to enable HD. Because there is onlt TOOL OPTIONS 1 and TOOL OPTIONS 2 in the menu. ( NO TOOL OPTION 3).

Hi, I have 37LG5000 with USB marked as 'service only' and I want to unlock/activate/hack it to be able to play movies from USB devices (external HDD). I ve been searching forums for hours, I have red all I can and Im still not sure about few things.
1) Some forums described unlocking USB in the LG series the same way as in LH series (downgrade firmware to 3.15 etc), but the firmware readme files dont mention supporting LG series. Also some forums mentioned that LG series uses *.bin firmware files, not *.epk, so its required to rename the file to 'update.bin', which smells fishy.
2) Some forums says that unlocking USB on LG series is not possible at all.
3) Some forums says that unlocking USB on LG series is possible only via IR hack.
4) Some forums describes unlocking USB using COM connection from PC - (damn, cant paste url, so I try it anyway without 3x w..) lg-hack.info/cgi-bin/sn_prntopic.cgi?cid=2674&fid=2677&tid=2714
5) One last interesting metod which Im not sure about - openlgtv.org.ru/wiki/index.php/LH/LG_series_USB_video_player_activation - basicly it says just to upgrade firmware to 3.75 + use LGMOD to add some setings for USB unlock.
Can anyone help me what should I do? The IR metod seems the most safe, but my phone is too old for this, I think. So please help. Thank you.

Press menu on remote and go to options but don't press ok, now press 7 times on the fav button now a screen apears with Software update (Expert) download version v03.15.00(not needed if you already have v3.15) and put it on a usb stick now the TV will see the file press ok and it wil downgrade or upgrade to v03.15.00.
Now The Service menu works again.
To acces Servicemenu press ok + ok for 5sec and a pw screen apears pw=0000(this you need to enable usb and xvid-mkv playback), go to option number 3 and set jpeg,mp3 to 1 and divx/xvid to HD.
For in-start (servicemenu)use the menu + menu buttons also 5sec and a pw screen apears pw=0000, Real servicemenu dont use this.
So here is now mkv and xvid enabled on my 37LF2500

Just downloaded the latest firmware from the LG website in NL.
Created the LG_DTV folder on USB stick.
Put firmware file in directory.
Put USB stick in TV.
It will immediately ask you to update.
After updating the firmware the TV will restart.
Put my .JPG USB stick back in the TV and everything is still working as it did before on 3.55.
Thanks LG

If you want alos to update the firmware just create a folder named LG_DTV in a root of a usb stick and mount it on TV.
If the firmware is newer than yours then a window will apper for update.

3. Tool Option4:

- THX Media Director: 1
- Picture Wizard: 1
I dont modified anything else. These settings are safe.
