Dear IFIX Engineers I have a big problem with programmerRT809H, which you made,  please help me if you are able to do so and ifyou know that ! Yours programmercannot correctly read and write eMMC software for my two  Sony TVs. : 1. Model KD-55X9005C withmainboard 1-894-595-12 and 2. Model KD55-X8505C with mainboard 1-894-596-22.The programmer RT809H you made is unusable for this Sony TVs and similar models!! Two my Sony TVs originally had a problems with constant restarting Android. I thought I hada problem with the software corruption or with dead Emmc. I tried hold Vol -and Power button for about 40 sec. it goes in Recovery mod but does not want toboot from USB. I read the Emmc H26M52103FMR 16Gb and shows that User date isdamaged and corrupted. I first read the content of the EMMC chip in the firstmainboard with my RT809H programmer with ISP cable. After that, I wrote theread this dump again in the same Emmc chip. After this, I tried to include myTV, but he was completely dead now! Before reading and and writing, my first TVgave signs of life and had a problem with constant restarting. After usingRT809H programmer My first Sony Android TV was completely dead! Desperatebecause of failure I didn't want the same procedure to repeat at the other ofmy Sony Android.I have bought the new same Emmc chip and I copied dump  which I read from that TV. Reading andwriting 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 longer gavesigns 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!
