LG HX906SB Home Cinema Software Update Issue: Stuck on Please Wait Screen After Restart

Hello, I have a home cinema as in the subject, I wanted to update the software, everything did everything correctly but after restarting only the Please Wait message is displayed, but the wait does not end, I will pull the plug from the outlet and turn it on again, the boot will appear . On the producer's website, such files are available,

How to upload it to the device, is there any chance to save it?
Buddy who dumped my previous post if I would like to take it to the site, I would endure it to my workshop, but it will not change, I have never encountered such a problem because I ask, there is some information on the forum but nothing has been resolved to the end, or it is not described after repair. If it breaks down to the end it's hard, but it would be fun to fix it.

Hello !
You played the first or the second file, first of all, and the bigger you separated them if you threw both, because you probably need to get the first one LG_HB_6100B33 and then the other LG_HB_6101B33, before installing HL09N_FW_378_120808! Try to upload again just follow the instructions! And that's all the equipment on warranty, or already after, because LG does not make problems, I once blundered the update and after bringing it to the site they did (of course I did not say it happened during the upgrade)!

Hello, I tried to upload all files via usb, nothing happens except for the message please wait, unfortunately the equipment is no longer guaranteed, in total I do not have any papers any more, if I do not succeed in this way I thought to pull out the memory and upload directly only if these files are suitable, I was still thinking if you can make this hard reset by mass, I did it several times in the navigations, I would not like to ruin it completely but there are a few possibilities, but do I really think?

Hello, someone else has already solved a similar problem because I'm vacuuming the subject again, maybe someone has already invented something?

Hi everyone I solved the "please wait" block with the reflow of the main processor, the one under the heatsink.
