Dear IFIX Engineers I have a big problem withprogrammer RT809H, which you made,  please help me if you are able to do so and ifyou know that ! Yours programmer cannot correctly read andwrite eMMC software for my two  Sony TVs.: 1. Model KD-55X9005C with mainboard 1-894-595-12 and 2. Model KD55-X8505Cwith mainboard 1-894-596-22. The programmer RT809H you made is unusable forthis Sony TVs and similar models !! Two my Sony TVs originally had a problems with constant restarting Android. Ithought I had a problem with the software corruption or with dead Emmc. I triedhold Vol - and Power button for about 40 sec. it goes in Recovery mod but doesnot want to boot from USB. I read the Emmc H26M52103FMR 16Gb and shows thatUser date is damaged and corrupted. I first read the content of the EMMC chipin the first mainboard with my RT809H programmer with ISP cable. After that, Iwrote the read this dump again in the same Emmc chip. After this, I tried toinclude my TV, but he was completely dead now! Before reading and and writing,my first TV gave signs of life and had a problem with constant restarting.After using RT809H programmer My first Sony Android TV was completely dead!Desperate because of failure I didn't want the same procedure to repeat at theother of my Sony Android.I have bought the new same Emmc chip and I copieddump  which I read from that TV. Readingand writing went without any problems but when I soldered back  on PCB after which I tried to include My TV.Unfortunately, another TV after the use of the RT809H programmer, no longergave signs of life, was completely dead ! This  iFix programmer RT809Hdestroyed two my motherboard ! What shit from the programmer ! ???
In my opinion the software of RT809h Is not good enough because there is noway to change CID of the emmc not able to change CSD_EXT file and when isreading and saving the date change some bytes in CSD_EXT register. Maybe I dida mistake with this programmer because it's capabilities are very limited. Ihope there is someone who bump into the same problem with RT809H .I have sent afew question to Ifix.cn.com but let's see what is going one these days. Inother words this programmer is pointless .. The developer did the jobsuccessfully and his operating program confirmed the success of the write butunfortunately this is false information!
Frustrated by the failure with my RT809H I sought help from a my friend whoowns a "Datamann 48Pro2C" Programmer. My friend has eMMC softwarefrom Sony TV KD-49X8305C which has mainboard 1-894-595-12. With the"Datamann" programmer, we successfully wrote that software to both ofmy boards, and behold miracles, both of my Sony TVs  now work normally! Inoticed in the content ofthe software for Sony Tv owned by my friend that it has 4X EXT_CSD data, whilethe program of my RT809H recognizes and reads only one single EXT_CSD data. !??? I got this software from my friend and tried to apply it on my RT809Hprogrammer. Writing with this software, my programmer starts and then theprogram stops and stays like that for half an hour, at the end comes themessage that "time out".Write EXT_CSD data doesn't work at all andjust blocks while ROM1, ROM2 and ROM3bin files can be over written individuallybut after that I get nothing! The TV stands as if dead, in the eMMC content itlacks 4X EXT_CSD data, please see photo ! That is not in the driver program forRT809H and it is not possible to read and write Based on this bad experience, Iclaim that there is a problem either in the RT809H programmer it self or in itsoperating program, it is not able toproperly read the software from the eMMCchips of these Sony TVs!
Best Regards Saud

Dear Friends !
EMMC chips Sony Android TVs  can not be written with programmer RT809H, Mainboards 1-894-596-22. 1-894-595-12  
and others !  I tried writen these eMMC chip with RT809H through ISP, that connected, I could see the eMMC.
I could read and write to it  but after writing the my Sony TV didn't turn on, it didn't show any signs of life.
I had the same problem with programming eMMC chips with Panasonic TVs! So Ifix RT809H programmer has major flaws,
he can't do writen this eMMC chips!

I managed to fix  my Sony android TVs! I was able to program the eMMC Sony Android TV chips correctly but not with
RT809H programmer. I wrote the software on a new eMMC with a „Easy-Jtag plus box“ with an adapter. Now my  Sony TVs
are working perfectly normal! My opinion RT809H  have a problem with the operating program? Operating program RT809H
does not allow correct chip partitioning and RPMB settings! Engineers-programmers at the IFix company who make the
operating program for the RT809H need to compare this operating program with the program of "Easy-Jtag plus box".
I think that the programmer RT809H would get more possibilities!
