BD Firmware Downgrade (SamyGO Proof of Concept)

[Pepe]

Can anyone Tell me how to downgrade my BD-D5300 to version 1022 ? i did an upgrade and i didn't know anything about DRT cinavia until i happened to me.

Lookinfg for information, firmware version 1022 the latest without cinavia stuff

I downloaded the firmware version 1022 but when if try to make my BD to looks for the firmware it does not detect it

I saw a post saying someones did the downgrade successfully i wonder if you can help to do it with mine.

Correct me if i`m wrong: this BD-D5100 player runs on CSP-D5100ZAB firmware (latest available on Samsung`s site ).

AND as you see on the first page, RUF firmwares aren`t supported by SamyGO and no plans for future. Apologies.

Thanks juuso, sorry I'm not a real tech when it comes to this stuff but my details are as below which is slightly different to what you have listed above... does that make any difference?

BD-D5100
BSP-d5100XYB-10.21.1

[juusso]

yes, no difference.

Hi Jas,

I am not familiar with the E series, but was there ever a firmware that did not contain cinavia in that series? If so there may be a possibility of a downgrade.
However, I don't believe there any imminent plans to include your system in the downgrade process.

I verified the BD D8090 with B-FIRHRDEUC_001107 firmware, but I cant get the samba shares to work, can anybody help me with this issue, I think because of the inter HDD the mountpoint is not right.... but I couldnt figure out the right code...
Hope anybody can help me

Hi,
does anybody know if is possible to dowgrade a BD-D7500B? I've installed the 1010.0 but that has Cinavia in it and it's driving me crazy!
I've downloaded the B-FIRBP7WWC 1008.2 ZIP file but i'm not able to downgrade.
I've tried with the DNS trick but looks like is not working with my model

Please help me.
Thanks,
Alessio

@juuso
No luck with downgrade B-FIRBPEWWC. Do you intend to load patched Samygo firmware on B-FIRBPEWWC for BD-E6100? I found that already rooted E-series TVs, but did not find anything for BD-E.

Many thanks! Downgrade worked flawlessly, no more cinavia.
