Hey raVenMaD, Your HE_DTV_W15A_AFADABAA file content is wrong. First, check where you unzipped the script. Like CDN_URL in your HE_DTV_W15A_AFADABAA file sugest, it's in something like C:\LG_DTV: or you put your firmware file to C:\LgDTVUpDater in LG_DTV folder: http://192.168.1.65/LG_DTV/starfish-dvb-secured-lm15u-badlands-453201-03.03.06-prodkey_usb_V3_SECURED.epk It's very bad place anyway. You must to unpack LgDTVUpDater archive to C:\LgDTVUpDater directory and CDN_URL in HE_DTV_W15A_AFADABAA file must be looks like: http://192.168.1.65/starfish-dvb-secured-lm15u-badlands-453201-03.03.06-prodkey_usb_V3_SECURED.epk Okay, let's do it... 1. Download Software_File(Version_03.03.06).zip and unpack it to C:\LgDTVUpDater\htdocs 2. Edit HE_DTV_W15A_AFADABAA file which you created in C:\LgDTVUpDater\htdocs <RESPONSE><RESULT_CD>900</RESULT_CD> <MSG>Success</MSG> <REQ_ID>00000000002517882427</REQ_ID> <IMAGE_URL>http://192.168.0.11</IMAGE_URL> <IMAGE_SIZE>699098426</IMAGE_SIZE> <IMAGE_NAME>starfish-dvb-secured-lm15u-badlands-453201-03.03.06-prodkey_usb_V3_SECURED.epk</IMAGE_NAME> <UPDATE_MAJOR_VER>03</UPDATE_MAJOR_VER> <UPDATE_MINOR_VER>03.06</UPDATE_MINOR_VER> <FORCE_FLAG>Y</FORCE_FLAG> <KE></KE> <GMT>10 Jun 2015 19:19:18 GMT</GMT> <ECO_INFO>01</ECO_INFO> <CDN_URL>http://192.168.0.11/starfish-dvb-secured-lm15u-badlands-453201-03.03.06-prodkey_usb_V3_SECURED.epk</CDN_URL> <CONTENTS></CONTENTS></RESPONSE> a. Copy all and overwrite with HE_DTV_W15A_AFADABAA file content b. Change 192.168.0.11 with your local IP address 3. Run downgrade process follow my tutorial 4.

That's great. Have a nice evening Dave.

Please welcome...

mtuna10... 1. Where you've got 04.10.10 firmware for UF8507? 2. Last OFFICIAL firmware for your TV now is 03.20.05. 3. Why would you downgrade to 03.13.85? 4. Your CDN_URL is bad. Port 80 is not needed. It must be like: http://192.168.2.131/starfish-dvb-secured-lm15u-badlands-4552-03.13.85-prodkey_nsu_V3_SECURED.epk Please try again or I can give you downgrade instructions to 03.20.05 if you want.

04.41.30 is OFFICIAL for your US LB7200 TV model. What firmware you want to install? Sent from my iPhone using Tapatalk

Hello mtuna10. I'll try to help you all, but now I need some rest. I should already get up, but I haven't slept. So, see you later.

Hey desrosiers13 Dave, 1. Download Software_File(Version_V04.41.30).zip and unpack it to C:\LgDTVUpDater\htdocs 2.

Well guys, I think that the name of TVs you both is HE_DTV_W15U_AFADABAA and that's why name isn't overwritten in in_dump file. I updated LgDTVupdater, so please try again to downgrade your firmware and let me know. If it fails, we will try to do it locally.

ellveez I'm glad that you successfully downgraded. Thanks for your post and tip for others.

It is not possible and trust me, you do not want that.

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.

Panasonic also... Nice. Totally agree. I don't understand that way. New TV, newest firmware and shit welcome again. My older LB5800 is still working perfectly. I think that's my last journey with fkng LG.

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.

Good for you, Demonrider. This app will now restart to free up memory on my LG650V when I searched for something in Google. I do not have any problems with other applications, only this shitty browser pissed me off every moment. I hope that you remain happy when you wake up. BTW I think that they already do not fix it. We need more physical memory rather than seeking a miracle in the firmware.

Fkng idiots. In my LB5800 I had no problem with that. I bought a better LB650V with great cosmic webOS and it sucks. :/

mbabakj, I need more info to help you.

Hi caerleonite. Here we are talking about firmware downgrade. If you want to talk about firmware versions, problems with it etc., feel free to talk about in WebOS TV Firmware version topic.

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.

You can use AirServer on your Mac or PC connected to TV, or if you just want to watch videos, pictures and listen to music, try Allcast, ZappoTV etc. for iOS.

KDaver, check your firewall and port 80. mariosavu10 had a similar problem: http://www.lgwebos.com/topic/1997-how-to-downgrade-webos-tv-firmware-tutorial/?p=4587

Hey pargo. I'm too late... Nice to see that you did it.

Seriously? 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.

That's great. We did it. Thanks for good cooperation.

First download Software_File(Version_04.50.43).zip and unpack it to C:\LgDTVUpDater\htdocs Then edit HE_DTV_WT1H_AFAAABAA file in C:\LgDTVUpDater\htdocs like this: <RESPONSE><RESULT_CD>900</RESULT_CD> <MSG>Success</MSG><REQ_ID>00000000002475918986</REQ_ID> <IMAGE_URL>http://192.168.0.11</IMAGE_URL> <IMAGE_SIZE>657983572</IMAGE_SIZE> <IMAGE_NAME>starfish-atsc-secured-goldfinger-38.arches-383802-04.50.43-prodkey_usb_V3_SECURED.epk</IMAGE_NAME> <IMAGE_CHECKSUM>0x1812e492</IMAGE_CHECKSUM> <UPDATE_MAJOR_VER>04</UPDATE_MAJOR_VER> <UPDATE_MINOR_VER>50.43</UPDATE_MINOR_VER> <FORCE_FLAG>Y</FORCE_FLAG> <KE></KE> <GMT>1 Jun 2015 16:30:47 GMT</GMT> <ECO_INFO>01</ECO_INFO> <CDN_URL>http://192.168.0.11/starfish-atsc-secured-goldfinger-38.arches-383802-04.50.43-prodkey_usb_V3_SECURED.epk</CDN_URL> <CONTENTS></CONTENTS></RESPONSE> Just copy that all and overwrite with HE_DTV_WT1H_AFAAABAA file content. Change 192.168.0.11 with your local IP address. Now run downgrade process as in the tutorial.

I need your location, firmware version after downgrade and model name from in_dump file - <MODEL_NM>??_???_????_????????</MODEL_NM>
