How To Downgrade webOS TV Firmware Tutorial

Recommended Posts

Hi,

 

Thank you for this tutoriel!

 

For them we have some trouble with windows 10 it's simple.

 

You need to type in an admin cmd : net stop http /y

 

If that didn't work, maybe like me you have skype.

Skype use the 80 port, you just need to close it.

SIMON, you have written this manual by yourself or stole someone else's instruction and assign it without leaving any references to the author? ;)

 

Seriously?  :huh: I wrote this tutorial step by step for LGwebOS forum users few days after successful downgrade based on description found on Polish blog. References to the author I left in archive by signing in a text file with my tutorial.

So, if you have any problem with that, feel free to PM me with your questions - here we are talking about firmware downgrade. Thank you.  ;)

Hi SIMON. I have an LB6300 and I'm getting "Update Failed due to Unknown Error". I cant figure it out. I've downgraded this TV before using the exact same method. Any idea where this error comes from? 

 

EDIT: I fixed it! I had to let it downgrade to 03.xx.x and then it let me downgrade to whatever i wanted. Thanks for the write up!

-This Downgrade Tutorial is for LG UB850V-

 

Tutorial for Downgrade to 5.00.04 FW!

 

1.here are the LGUpdater Folder with my manual settings.

MEGA

2.Edit the AcylicHosts File with your PC IP Adress.

#############################################################################
# #
# IF YOU MAKE ANY CHANGES TO THIS FILE YOU HAVE TO RESTART THE ACRYLIC DNS #
# PROXY SERVICE IN ORDER TO SEE THEIR EFFECTS. #
# #
# This is the AcrylicHosts.txt file. #
# #
# It contains predefined mappings between names and addresses exactly the #
# same way the native HOSTS file does. #
# #
# The format is: IPADDRESS HOSTNAME1 [HOSTNAME2] [HOSTNAME3] ... #
# #
# Where IPADDRESS is in quad-dotted notation and HOSTNAMES are strings. #
# #
# The separator between IPADDRESS and HOSTNAMES can be any number of spaces #
# or tabs or both. If the HOSTNAMES contain the special characters '*' and #
# '?' a (slow) "dir" like pattern matching algorithm is used instead of a #
# (fast) binary search within the list of host names: #
# #
# 127.0.0.1 ad.* ads.* #
# #
# If a HOSTNAME starts with the '/' character instead it is treated like a #
# regular expression (also very slow compared to a binary search): #
# #
# 127.0.0.1 /^ads?\..*$ #
# #
# Note: More info about the regular expression engine and its syntax can be #
# found at: RegExp Studio Regular expressions,RegExp,Delphi,Pascal,FreePascal,Kylix,Libraries,VCL,CLX,Tools,files utils,math,string utils,parsers #
# #
# It is also possible to specify exceptions when regular expressions or #
# pattern based matching is used. If for example we would like to filter #
# out all ads.* like domains except for the ads.test1 and the ads.test2 we #
# should write: #
# #
# 127.0.0.1 ads.* -ads.test1 -ads.test2 #
# #
# Note: A line starting with the '#' character (and everything after it if #
# it's found within a line) is considered a comment and therefore ignored. #
# #

Hi all - for what it 's worth, I just spoke to LG helpdesk about this WebOS debacle causing my tv to crash every 15 minutes. I have been on the phone to them four times or so over the past two weeks. Last week I was told an update would be within days; today they backtracked - said previous helpdesk colleague was wrong to say that; said that LG doesn't tell them when fw releases or patches will be issued.. Nice..

Ciao Zen.   ;) Don't be angry, life is too short. We all know that webOS 1.x in our TVs is very nice piece of shit, but there are more important things in our life and things like that it's only shitty decoration. Anyway, in answer to your question - I think yes, it will be good also for your TV. Just try to downgrade with my instruction and when you done, go to TV menu and do update by OTA to next firmware which you want. If you get any problems, let me know to help you more.

Good evening all,

 

i am having some difficulty downgrading from the Beta 05.10.02 version to try the latest 05.00.15 version, so any help most appreciated !

 

I'm not really an IT network guy, so not so sure on whats going on.

 

step 4)    After obtaining MY IP ADDDRESS, do i need to remain connected to the internet for this process to work ?

 

step 7) and 8) the .bat files open and remain open.  ( After clicking allow by firewall )

 

however step 9) i am not so sure about.  So from a hardware perspective, i now have my PC connected via an ethernet cable to the TV.

 

I goto NETWORK settings, and disable WIFI connection. I then proceed to WIRED CONNECTION (Ethernet ) untick set automatically and change DNS SERVER to my own IP address

BUT i leave IP ADDRESS,SUBNET MASK, and GATEWAY as they are - is this correct ?

 

I then click CONNECT, and i get a LG TV MESSAGE 'Wired network is connected'

 

However in the little graphics under the large text EDIT IP, i get a cross by DNS and the internet symbol and it reports 'No internet via Ethernet'   - Is this as expected ?

 

Now going into GENERAL / About this TV / Checking for updates - i get the message 'It may take a few minutes' then no update found.

 

So i'm not sure if the tv is going through my pc or if i just dont have a valid update file, am i meant to put an .EPK file in HTDOCS like an email earlier ?

 

Thanks in advance for any pointers . :)

 

My TV model is a 55JL9000-ZA,   UK.

So think i have got a little further.   My initial IP address i was substuting was the routers IP and not the pc itself.

So doind a CMD line, IPCONFIG - i got the IP address of my ethernet port. Using this address i can now see in the .bat file cmd window:

 

2015-10-11 16:00 Tresolver.Execute: Request ID xxxxxx received from client xxTV IPxx regarding "lgtvonline.lge.com" of type A.

 

So i am guessing that i am now receing comms from the tv and it is requesting the lgtvonline.lge.com site.

 

However i can not get any further, nothing else happens. Another site suggest the in_dump.txt file gets modified, but mine does not get re-writen. ( Have tried deleting it, but it does not get re-created )

 

Any ideas on what i can do to fault find this stage ?

 

Should i be able to ping xxTV IPxx and get a response ?  I have tried this but get timeout.

 

thanks.

Hi dtosun. I need your TV model name from in_dump file - <MODEL_NM>HE_DTV_????_????????</MODEL_NM>

 

Please do steps from 1 to 10 with my tutorial then don't accept upgrade/downgrade. After that go to C:\LgDTVUpDater\htdocs folder and open in_dump.txt file. Copy TV model name and post it here for more instructions.

Exactly what info is needed.

 

I know that your TV model is UF770V. To help you I need your location, current firmware version and info on which step you stuck with problem. Also TV model name from C:\LgDTVUpDater\htdocs\in_dump.txt file - <MODEL_NM>HE_DTV_????_????????</MODEL_NM> may be needed.

      Hi All,
      Has anyone had a recent update of the OS on their TV to 4.7.050204 (goldilocks2-gulaga) ?
      The reason I ask is that the IPTV channels on my TV seem to have borked these channels as I now get "Invalid Service"
      floating across the screen. I'm pretty sure these channels worked before the update.
      I'm referring to channels such as Now 90's, Planect Knowledge, The Sports Channel Network etc. So these are NOT APPS but
      TV Channels showing up on the guide and still show the programme details.
       
      This TV is only a week old, and I think I'm going to be bounced between the retailer and LG as it seems to be a software issue.
      Does anyone have similar experiences and have you resolved the issue ?
      TIA

      Question: Why does LG's website say I should check this forum to see if 3rd Party Bluetooth Headsets with work completely and correctly with LG sound sync and WebOS, when LG has not or will not publish a list of which 3rd Party Bluetooth Headsets are tested as compatible with specific LG TV models? 
      We recently purchased an LG 55UM7300PUA (2019) TV and have a question about which 3rd Party Bluetooth Headsets that are compatible with LG sound sync and WebOS...  My wife wants to listen to our 55UM7300PUA TV through a set of Bluetooth Headphones while the TV Internal Speakers are turned off...
      It seems that LG's USA website needs to be updated because LG's search results about our 55UM7300PUA model seem incomplete. The LG Tech Support website does not list the 55UM7300PUA as a TV nor Smart TV product and no 55UM7300PUA or 55UM73 manual is listed in search results.   I finally found the Owners Manual for our 55UM7300PUA through a Google search, but this PDF Owners Manual I downloaded does not say if our 55UM7300PUA supports LG sound sync or which manufacturer/models of Bluetooth Headsets . 
      I am disappointed by a lack of technical support from LG in past forum discussions regarding which 3rd Party Bluetooth Headsets with work completely and correctly with LG sound sync and WebOS.  LG Technical Support is forcing customers like me to buy Bluetooth Headsets at our expense, they ask us to do their testing with a lack of specific 55UM7300PUA documentation, and they direct us to "refer to headset model names in user guide" that are not simply listed.
      Does our 55UM7300PUA support the use of Bluetooth Headphones and is "LG sound sync" required for use with Bluetooth Headphones?  Why should we have to test 3rd party Headsets at our expense when LG Tech Support should specifiy which OEM and 3rd party Headsets work with which LG TV models?
