Firmware Hack And Firmware updates LG LH/LF Series - Page 2

post #31 of 697
You can try to put 3.55 on a stick, insert into the USB and try to start the TV. Maybe you have luck. Why did you try 3.40 and not the 3.55?
post #32 of 697
that's what I tried... 3.55

I wrote 3.40 by mistake

already tried what you suggest but no luck

thank you very much!
post #33 of 697
Well you can always say that tv broke on it's own, while updating the firmware, which is true, and that's what i would try.
post #34 of 697
You are right but I think LG does not authorize updates over USB therefore maybe am not covered-even though I had no idea about warranty issues over a simple update!
post #35 of 697
They fully authorize updates over USB, that's why you can get them on the official LG website You can also say that your has stopped working one day and that's it.
post #36 of 697
oh thanks!

I thought they didn't ... then it's not completely my mistake if firmware file was broken or something...
post #37 of 697
for what reason they dont releases the firmwares publicly ? i'm interrested getting one but that sucks !
post #38 of 697
they are available publicly.. it's just that i cannot find it right now, but some more googling should do it

Hi,

I read about DTS problems, and I interested if somebody try to connect the digital output to a AV receiver. I curious if DTS sound Pass-Through to the digital output.
post #41 of 697
this sounds like a good idea but with all the problems of people bricking their tv, id rather call an lg expert and have them come to my house to update the firmware professionally and properly under the warranty. and besides, even if it does remove the ability to watch videos and play mp3z via the usb port on the back ,who flipping cares, My LG Blue Ray player does that via its built in usb port anyway, so im not at a loss, and it was an only an extra 98 bucks canadian for that feature, oh and it plays BLUE RAYS too. .

Amazing, works a treat!

Is there a maximum file size of .mkv file that the TV will play does anyone know? As if the USB stick has to be Fat-32 then it'll be 4gb right?

But it if can be NTSC then you can play any size file.

Cheers

Yes you can use NTFS for larger files, also tested some time ago a 13GB mkv and thats worked without a problem.

I enabled USB support for photos, music and movies using the service remote trick in a North American 47LH30-UA with 4.0.5. (you can do this with certain universal remotes, winlirc or a pda if you don't have a tecnician's remote, see other posts, and DON'T touch your firmware since you don't need to).

I noticed the Bluetooth settings and people saying that enabling it won't do anything if the hardware isn't present.

What's interesting is that looking through the firmware kernel, the Bluetooth hardware is for an LGE usb Bluetooth adapter. Looking in the code, it looks like it's a CSR/Bluecore USB but that's all I can tell. This was a European firmware version, but since the North American service menu has the Bluetooth option, presumable the NA firmware has support built in.

Since the driver is there, I'm guessing you can enable BT functionality in your set even if the hardware isn't built-in: just plug in a compatible BT usb stick.

The LG software supports bluetooth headsets and maybe more functions like photos.

1. Anyone know where to get a compatible LGE USB Bluetooth adapter? Does LG sell one (for one of their phones perhaps)? Belkin makes a CSR based BT USB adapter, but not sure if it will work.

2. Anyone tried enabling Bluetooth, with or without the hardware?
post #45 of 697
Thats a huge find. What is intriguing is that all the bluetooth enabled models have "Integrated technology" as opposed to supporting an external dongle. Now obviously LG is using USB bluetooth drivers for the onboard chip in these models if that is possible?! All the warnings about enabling Bluetooth in these forums I think are pre-emptive precaution not based on logic.

Now consider the USB HD DivX hack itself. The hardware chipset for decoding H.264 1080p/720p is available in ALL models. That is why we are able to enable HD playback in the first place. We all know the kind of humongous processing power decoding H.264s can take up especially at 1080p. It makes near mince meat of a Core 2 duo!!! Only a Quad rides well with some headroom. Point being if LG can include the necessary hardware for H.264 decoding in "non- HD media USB playback" models, by that logic the bluetooth chip is most likely integrated in "non-bluetooth models" as well. Does not make sense to strip out the integrated bluetooth chip, when it can be just disabled in the firmware menu ( Kinda sounds dumb too for a corporate marketing strategy on the sly. Well many companies do that. Canon for instance disables many features in low end cams to sell their high end stuff).

Am still getting my hack remote on order, so can't back up my theory myself at this point.

I tried enabling bluetooth on a North American 42LH40. It caused the set to reboot continuously every 10 seconds, so obviously the hardware is absent.

I was just barely able to get into the service menu in under 10 sec and turn it off, otherwise my TV would've been toast. So my advice is don't do it.

Even though the red stand by light is working, nothing else seems to work. Do you think I somehow bricked or damaged the TV? is a way to reverse-restore-reset the procedure back to factory settings? or somehow get it flash the original firmware? ...

These will probably not work, but you can give it a shot:

1) From http://forum.ixbt.com/topic.cgi?id=62:16479 (russian, translation follows)
To recover an apparently dead lg set you'll need

* a computer with a serial port
* a null modem cable
* a terminal emulation program with file transfer capability (zmodem protocol)
* a good firmware file (*.epk)
* a little care
* a lot of patience

If you don't understand the meaning of anything in this list it's better you call lg service

Warning, incorrect operations could irreparably damage your set

This is the sequence of actions:

1. turn off the tv (by removing the power cable or using the on/off switch, all leds must be off)
2. connect the service port on the tv to the computer serial port with a null modem cable
3. start the terminal emulation program an set the speed at 115200, 8 data bits, no parity, 1 stop bit, no hardware or software handshake
4. turn on the tv and at the same time press Esc on the keyboard. It may be necessary to press Esc more than once
5. if everything goes well, you'll be greeted by a "Mstar #" prompt (here you can write help to obtain a list of available commands in the u-boot bootloader)
6. issue the swuz command (software upload zmodem). the tv will await the file
7. in the terminal emulation program select the correct firmware file (.epk) to send to the tv
8. don't touch anything and hope there's no power cut (it's a long process!)
9. once the file has been successfully transferred, turn off the tv
10. disconnect the serial cable
11. turn on the tv and hopefully it will work
12. dance, sing and think how you can thank tester13a (the author of this procedure)

2) If you can get the set booting well enough to enter menus but other functions are still broken, try the restore procedure contained in this post: http://www.avforums.com/forums/lg-ow...l#post11030066

doing this in 10 sec !! you re so fast man.
post #49 of 697
Thats what happens when you are on the dangerous edge of killing your unit....
Ok thanx for the tested warning about NOT enabling bluetooth (very glad your TV survived the ordeal and is back to good health!). Btw LG is using proprietary Broadcom bluetooth SoC technology, so it makes sense if they are stripping out the chip from non-bluetooth models to save on license fees, which looks like the case now.

I tried enabling BT in the menu and also had an old CSR based BT dongle plugged into the USB.

The TV menu pops up with a nice big Bluetooth icon that has a submenu for turning on BT, headset options, pairing etc. but then the TV reboots (I've confirmed this enabling verbose boot on the serial port in mstar/u-boot)


Without the USB dongle, there is no BT menu, but I still get the resets (I didn't realize this before). Anyway, it doesn't seem like a big deal to disable BT again in the service menu.

I'm curious about what possible BT dongle might work. I've looked at the kernel binaries and it seems to mention CSR with Bluecore but nothing else. Another poster mentioned Broadcom but I don't see this in the kernel, but I suppose it's possible if the TV has different firmware.
post #51 of 697
That makes it confusing as to what BT is being used in older models. Am not able to post a link here from some reason...but here is the press release if it adds up to the BT puzzle......


Broadcom® Bluetooth® Technology Enables New LGE Digital Televisions to Interplay with Cell Phones and Wireless Headsets
--Wireless Transfer of Photos and Music from Cell Phones to the TV as well as Streaming Audio from the TV to Stereo Wireless Headphones Provides Enhanced User Experience
IRVINE, Calif., July 27, 2009 -- Broadcom Corporation (Nasdaq: BRCM), a global leader in semiconductors for wired and wireless communications, today announced that LG Electronics (LGE) has integrated its advanced Bluetooth® technology into a new line of digital televisions (DTVs) that are now shipping. Broadcom® Bluetooth capabilities featured in these new LGE televisions enable an innovative and personalized user experience by allowing consumers to connect other devices, such as wireless stereo headphones and cell phones, to the TV set.

By enabling the cell phone and headset to interplay with the TV via Broadcom Bluetooth technology, LGE takes advantage of the existing ecosystem of Bluetooth devices to bring advanced audio streaming and digital media sharing features to consumers. Broadcom's technology also positions the cell phone for future applications such as functioning as a TV remote control or a QWERTY keyboard input device for TV-based widgets and electronics commerce applications.

Additionally, Broadcom Bluetooth technology allows the new LGE TVs to act as a wireless docking station for MP3-enabled cell phones and portable media players (PMPs), allowing music and other audio to play over TV speaker systems. It also allows 'picture push' capabilities that enable users to wirelessly move digital photos and other graphic files from Bluetooth-enabled camera phones to the LGE TV for viewing and sharing.

"Consumers are continuing to discover that Bluetooth is much more than just a wireless headset, with the technology rapidly gaining adoption in digital televisions," said Fernanda Summa, TV Product Manager, LG Electronics. "Broadcom Bluetooth technology provides the right combination of features and performance for embedded and consumer electronics applications, delivering advanced multimedia capabilities and low power consumption driven by Broadcom's expertise in mobile handsets."

Wireless Technologies Changing Digital TV Experience

The Bluetooth ecosystem continues to expand, bringing relevance to the technology far beyond the traditional mobile phone/hands-free headset applications for which it is best known. Bluetooth connectivity enables viewers to leverage common DTV features, such as high-end speaker systems and large format display capabilities, to enjoy media content stored on their MP3 players and mobile phones (with digital photo capabilities) while also allowing viewers to privately enjoy high quality sound streamed to headphones without cords or wires. Broadcom estimates that the total available market (TAM) for embedded Bluetooth solutions will be more than 938 million units by 2012.

"The increasing adoption of Broadcom Bluetooth technology into digital televisions and other consumer electronics devices is driving an emerging connectivity ecosystem, allowing existing products with Bluetooth connectivity like cell phones and wireless headsets to play new roles," said Craig Ochikubo, Vice President & General Manager of Broadcom's Wireless Personal Area Networking line of business. "Broadcom is helping to drive this trend and we look forward to our continued collaboration with LGE to transform consumer interaction with these devices."

Broadcom Bluetooth Technology

Having shipped over one billion Bluetooth products, Broadcom offers the broadest family of Bluetooth silicon and software solutions for mobile phones, PCs, wireless headphones and headsets, peripherals, gaming and other applications. Broadcom's Bluetooth solutions are widely recognized in the industry as the most broadly deployed and feature-rich solutions. The world's largest manufacturers of consumer electronics, mobile phones and personal computer products rely on Broadcom Bluetooth technology to provide their customers with a unique, intuitive and rich user experience, increasingly free of wires and cables.

Additionally, Broadcom offers the most complete Bluetooth software in the industry, maintaining end-to-end integration of its protocol stack, application profiles, and audio enhancement and processing algorithms.

With the increasing availability of Internet-based video and other digital content, many CE vendors are also adding Wi-Fi® to provide easy access to multimedia content on digital TVs, set-top boxes and Blu-ray Disc® players throughout the home. Broadcom has integrated its wireless hardware and software into several of its industry-leading video platforms to accelerate the development of connected consumer electronics.

It could be this integrated bt adaptor from Broadcom the bcm4323 , maybe similar to the one in the pic.

post #54 of 697
AFAIK the hack has not yet been reported to work on Asian models. It has however worked on American and of course European sets.

A word of caution DONT apply the FWs in these forums to your set. These are ONLY for Euro units. The best approach IMO would be the IR/Universal remote method

Ok I know, so my unit also has the hardware to run 1080p HD as you said?
Can you show the link to the IR/Universal remote method, and does this method alone can unlock the HD ability or it needs a new FW. I can press Menu+Menu to see the current FW on my set, it's 3.18b

Thank ayko, but I see this method only helps to enter the service menu which I already did by pressing Menu-Menu keys on TV and RC. There is NO Tool Option3.
So, this may be for Euro sets only. I probably need a new FW.

There is another service menu. Press Enter-Enter on TV and remote. Same password (0000). The keys might be called Ok instead of Enter on your set (on the remote it's the round button in the middle of the arrow keys). Tool option 3 is in there on my set, 42LH40.

Be careful in there! Change only the DivX setting or you may kill your set. I've also changed the Tuner Option setting safely to improve my broadcast reception. Settings take effect (almost) immediately upon change, no need to press any kind of enter key, so even cycling through parameters to see what's available can be very risky.

On my set, pressing Menu-Menu shows: model, sw ver, mode, utt... tool option1-2, Option 1-4, sytem control, power history etc. (there is no Tool Option3)
Pressing OK-OK shows EZ adjust menu: ADC adjust, Sub B/C adjust, Green Eye-check, w/b adjust, white pattern, edid d/l

Is it possible that Tool option3 is a Sub menu of the above items ??? I didn't go into them.
