Hi guys,

I own the 60LA8600-TA (Australian Version).  Last week my TV did an automatic upgrade from the latest Netcast firmware 04.28.07 to the new WebOS firmware 04.29.01.

 

After this upgrade the TV could no longer play DLNA content via LG's player or Plex.  I came to this forum and found this downgrade procedure and it worked perfectly except for one thing, My TV was permanently upside down.

After resetting the unit and fiddling around a bit I could not flip it back so I tried another firmware downgrade.  This is where things got far worse.  I must of, in my haste, Selected a foreign firmware.  Upon flashing to this firmware my TV is now in what I assume is Hebrew language (indistinguishable characters) :-(

 

I promptly downloaded the latest AU firmware again and tried to flash back.  But now the TV will no longer find an update via the original method on this site :-( Just says what I assume is no update found.

After a lot of research I managed to use the Android LG Service Remote App with a Galaxy S5's IR blaster to get into the service menu and flip the TV back to the correct orientation by turning off mirror mode.  I also read that a Factory In_Stop may revert to factory firmware but the app does not have that function.

 

Basically I just need to flash back to AU firmware and all will be well.  This is the current In_Dump from my set:
 

<REQUEST>

I have created a clone of the original HE_DTV_NC4H_AFAAABAA I used to downgrade my set, to this new Model NM HE_DTV_NC4H_AFAAAIAA but the TV does not see the firmware or local host for some unknown reason.  The TV simply shows no update available and the acrylicconsole on my PC is showing the TV pinging the standard servers that I have forwarded to my internal static IP.

Can anyone help me out with this one?

Any help is greatly appreciated.

So I tried SMX's version of the downgrade and the TV actually picked up the update from my PC this time... Problem is, after the update got to 100% and said completed, rebooting.  The TV now turns on, Shows the LG Logo then goes to a grey/black screen and does nothing else indefinitely :-(

 

I'm assuming the motherboard has now been bricked?

I currently have it off at the wall draining to see if it will recover but i highly doubt it, I used the original OEM firmware epk that worked perfectly days earlier too which is what really throws me.

I followed this to the letter:

Hello Simon,

Thanks a lot for all your help and patience. Thanks to the method @hepmisafir found, I believe that I will finally be able to downgrade my dumb TV :)

 

Hi mtuna,

 

any chance you write detailed tutorial, I'm heaving trouble downgrading my 49UF8507 with both options but I fail at both of them...

It's not possible to flash all updates safely. The TV does *NO check*.

Essentially, what you need to do is flash a Full Firmware to avoid a brick.

Full firmwares (we could also call them milestones) are epks that ship all the partitions bundled in.

On the other hand, Partial Firmwares only ship SOME of the partitions.

The problem is that while new partial updates are designed to work on older partitions, new partitions don't expect an older version of other partitions to be flashed, and may act weirdly, crash, or just do nothing at all.

How to know if the firmware you're going to flash is good? The only true way would be to extract the EPK and check it out...but there's a trick

You can perform the following steps to get an EPK that should be good to go and safe:

-> Dump the TV NSU Request

-> Modify the reported firmware version to be something older than you currently have. You may set it to be older than the first released version (in some cases you can get the first version ever released by doing that, or the first milestone). Or you can incrementally reduce the version until you pick an update. My recommendation would be start from a low MINOR, but with the same MAJOR, so that you don't get another partial update.

-> Send this modified NSU Request to LG (i have a tool that i may polish up and release for this task)

-> Copy the CDN Url, download the epk on your PC, and spoof/serve it with NSU_EMU

ALSO check the size of the epk file. A small epk file is unlikely to be a full upgrade.

:)

Now unfortunately, about your brick, there's not much you can do. Your only hope to get it fixed is to try and get serial working, but at your current situation you would need to disassemble the TV, and i'm not completely sure about the recovery procedure in case you get a working connection. I DO have a theory, but i never worked with a bricked WebOS device and someone willing to take a closer look..yet ;)

Hope this post can be helpful to others.

@SIMON: You should add this as a warning

:)

P.S. About the NSU_EMU rewrite i had in progress...i'm lacking time lately, and my main PC has been out of service for a while. I need to get some time and reorganize my storage space before i can get going again.

Hi dear friend. My name is Juan, I'm from Argentina. Sorry for my poor english. I'm writing you because of your topic "How To Downgrade webOS TV Firmware Tutorial". I need help please, cause my TV model is "49UF6400-SA" and I follow all the steps but not having any solution.

Maybe it's because my model is not present in "local" or "online" folders. For that reason, I searched an updated version of LgDTVUpDater and I found this link:
link hidden, please login to view
 with the next download: 

 

 

There's an updated version of those folders and maybe the folder "UF640" is the one for my TV model. But I don't know how to update all the program to use it. Please please please, can you help me?

 

The actual firmware installed on my TV is 03.10.60

 

Thanks in advance!

I came across your name when i was browsing this site. I hope you can help me on the below.


I have got an lg tv and when i try to do a manual firmware upgrade by clicking the check for update using the remote,both wired and wirelessly, i get a message saying 'update failed due to decrypting data error'. I was wondering what that meant and how it can be fixed.


Would be grateful if you could help me with my problem

Olá Simon, 

 

Eu sou do Brasil, assim como o @newbie, e estou tendo problemas com minha TV e gostaria da sua ajuda.

 

Eu tenho uma 42LB6500, Firmware 05.05.01, Modelo 42LB6500-SF, versão WebOS 1.4.0-2518 (afro-ashley) e o aplicativo do NetFlix não está carregando mais os vídeos. Somente este aplicativo não funciona corretamente. Tentei fazer o downgrade para a versão 04.65.05, mas sempre dá erro, tanto quanto tento o downgrade com o arquivo no diretório "htdocs" quanto online, pelo link https://su.lge.com... "Falha na atualização erro na descriptografia... ": "Falha na atualização decorrente de erro desconhecido."

 

Já tentei várias formas, firmware's diferentes, LGDTVUpdater diferente e nada, sempre dá erro. 

 

Minha TV é só para NetFlix e agora virou um enfeite de parede.

 

Me ajuda, por favor?

É possível fazer o downgrade da LG 42LB6500??? Eu não consigo fazer o downgrade e já tentei olhar os logs do Apache, mas não encontro nada que possa me informar onde estou errando.

 

Estou começando a acreditar que o problema na verdade é que a minha TV não é possível fazer o downgrade.

Hello Simon !

Thanks in advance for your big work ! (sorry for my bad English)...

Two days ago I test your way but I've some doubts, I put a different range 192.168.1.2 local computer... and for localhost AcrylicHosts all changes less local address (127.0.0.1) obvious, the doubt is I can't see where step I've to put my *.pek file (firmware file) and if downgrade what's is the version of default if not put my firmware file?  

Data:

My LG TV model is 60LB870V and I've realease 05.00.35 but I want to change by 05.00.15 because the flash I think is better... 

In the C:\LgDTVUpDater\htdocs there are a file HE_DTV_WT1M_AFAAABAA and inside I think that there are some parameters which in other website tell to modify for example:

<RESPONSE><RESULT_CD>900</RESULT_CD><MSG>Success</MSG><REQ_ID>00000000001400299533</REQ_ID><IMAGE_URL>http://snu.lge.com/SWDownload.laf</IMAGE_URL><IMAGE_SIZE>619206024</IMAGE_SIZE><IMAGE_NAME>starfish-dvb-secured-m14tv-25.ashley.m14tv-2507-05.00.15-prodkey_usb_V3_SECURED.epk</IMAGE_NAME><IMAGE_CHECKSUM>0x11ef4680</IMAGE_CHECKSUM><UPDATE_MAJOR_VER>03</UPDATE_MAJOR_VER><UPDATE_MINOR_VER>23.24</UPDATE_MINOR_VER><FORCE_FLAG>Y</FORCE_FLAG><KE></KE><GMT>10 Aug 2014 04:47:19 GMT</GMT><ECO_INFO>01</ECO_INFO><CDN_URL>http://su.lge.com:80/GlobalSWDownloadCdn.laf?IMG=/201406/starfish-dvb-secured-m14tv-25.ashley.m14tv-2507-05.00.15-prodkey_usb_V3_SECURED.epk</CDN_URL><CONTENTS></CONTENTS></RESPONSE>

IMAGE_URL too change for 192.168.1.2  but only donwload at half... but stopping... and never restart the TV... 

My questions are: The image size is not necessary change? because the initial file was another image file like a "**angeles27**" sorry but right now I don't stay join the PC TV...  and if not put my "pek" file how update or what's realease update or perhaps is then when plug my USB Stick because only change the state for new firmwares... sorry but is my first time to downgrade the TV and I've a little fear for a possible brick.

Well I think that is not necessary how I said put any pek file... until restart TV whit USB Stick...  is for that way the correct process? and someone test with LG 60LB870V downgrade 05.00.35 to 05.00.15 without problems? 

Thank you very much in advance !

Hi, any chance of the necessary code to do this without having to create a Windows VB please? My machine is a mid-2012 spec Macbook Pro A1278 running Mint 18.1 & Cinnamon desktop UI and Auld Fecker 17.6 (Debian sc based) for the PT work. I do have access to a Dell desktop but that is also a factory Linux box and I'm not prepared to downgrade either to Windows just so that my TV can be hacked on the offchance that there's a tangible advantage for doing this downgrade, which there may well be but given that the TV works properly I'm only needing to find out for myself which seems fair.

Also, does this affect the warranty?

 

TIA,

 

Seam.

Can someone help me, I dont know what I'm doing wrong.

 

I have a [LG] webOS TV OLED55B6V I'm trying to downgrade because they ruined HDR game mode and i want it to be bright again.

 

I've tried everything but my tv wont connect to the local host, I've turned of my firewall etc nothing works.

Anyone can help me or give me the correct firmware that's before 05.30.03?

 

im a noob in this.

 

thnx

Can you tell me if you can make an official downgrade? After every upgrade, my TV image quality decreased, I waited few official upgrade but after every upgrade the image quality decreased (very little differences in shades, like the screen were aging).  Apple has the same policy after every iOS upgrade the iPhone becomes "older" :-) .  I learned the lesson, if I don't have a real reason for an upgrade I will keep the original firmware. 

After the firmware downgrade, my tv have a very good image like a new one. This was my downgrade reason.

good luck

      On our LG G1 OLED, when watching a program on Binge, the Binge app restarts itself every 20 minutes or so with a message about needing to restart to free up memory. Power-cycling the TV doesn't fix the problem, nor does running the "Memory Optimiser" function from system settings. None of the other streaming service apps we have on the TV have this problem - Prime Video, Stan, Netflix, Disney+, Britbox, ABC iView, SBS On Demand, Youtube. Those are the only other apps installed on the TV. I've checked the LG WebOS version and checked for app updates, and everything is latest version.
      If I run the Binge Android app on my Chromecast with Google TV, it works without any problems when streaming the same programs.

      Samsung has made fridges with touchscreens before. LG has made fridges with doors that turn transparent to show you the inside. This year at CES 2018, those two ideas are finally merging into one with LG’s new InstaView ThinQ smart refrigerator, which features a 29-inch touchscreen that becomes transparent if users knock on it twice.
      LG actually tried this two years ago, with a version called the Smart InstaView Door-in-Door that ran a full version of Windows 10, but it’s not clear that the company ever shipped the Windows version.
      This version uses the touchscreen to manage your food using LG’s webOS software and Amazon’s Alexa, which will let you tag food with virtual stickers and expiration dates and get automatic reminders when things are running low or about to go bad. There’s also a wide-angle panoramic camera on the inside of the fridge that will let you remotely view your fridge while you’re out and about to check and see if you’re actually out of milk or not.

      Unfortunately, the only image that LG has shared showing the fridge is a low-resolution shot on its YouTube page banner, but it seems that you’ll be able to still use the screen while it’s translucent, allowing you to tag food directly in a vaguely augmented reality-esque move.
      LG is also touting how all of its ThinQ kitchen gadgets can talk to each other to make kitchen tasks easier. So your ThinQ fridge can talk to your EasyClean oven, which will help you cook food through step-by-step instructions from the recipe app from your fridge. Then, your EasyClean oven can notify your QuadWash dishwasher about the kind of meal you cooked, so it can more efficiently select a wash cycle for that dish. Of course, all this requires spending thousands of dollars replacing every appliance in your kitchen (and if this all works as well as LG claims it does), but it’s still an intriguing vision of a Jetsons-like future utopia.
      No price or release date for the InstaView ThinQ refrigerator or any of LG’s other new appliances have yet been announced.

    • Solution For That Pollution
    • By Ramesh Chand Vishwakarma
      It is unprofessional on part of LG TV that they do not resolve the basic issue of adding app gCmob in their app store.
      My 50UT80506LA LG WebOs TV does not support my office security camera system via wifi to TV.  We need (gCmob app) in list of app.
      I can't connect my office camera via Wi-Fi to LG-TV. No body in LG TV technical team is proactive in resolving the issue of customer. They are more happy to befool the customers, rather than looking for technical solution through wider thinking.
      Please talk to you top management and make a visit to our office to understand the customers plight..
      Please respond to customers needs.
