Hello  dear friends !
Nice to meet you.
I bought the RT809H and installed the software normally.
However, I can not to write a Toshiba chip THGBM5G5A1JBAIR with EMMC ISP.
Of course, neither reading nor writing is possible. MyRT809H programmer finds this chip in automatic as well as manual search. Andnothing more can! I tried with EMMC_AUTO_ISP and  with manual searh as THGBMBG5D1KBAIL_ISP, butin both cases I get the same writing problem . When writing, my programmer startswriting but it immediately stops with the message: "Write error, operationterminated". The program then blocks and whitens and I get a message tolook for a solution on the internet. After I click on it the programautomatically restarts and I have the same problem again, I can't write thischip!To note, I did everything correctly. I found and connected the points:CMD, CLK, D0 and GND. I did not extend the original ISP cable. I cut the CMD,CLK and D0 lines between the eMMC and the main processor. I briefly connectedthe quartz crystal of the main processor to ground. I gave the correct externalsupply voltage to the eMMC chip VCC / VCCQ = 3.3V. Despite all this, I have thesame problem. To note, with other eMMC chips as well as mainboards from anderesLCD TVs I don’t have this problems ! Here is information about the TV and themotherboard with which there is a problem: Panasonic LED TV modelTX-39ASW654  sch. LA51, mainboardTNPH1077 1A, eMMC IC 8903.
I want to know what causes it.
Please , I ask for your help, thanks in adwance!
Thank you.

Dear !  I have problems only with Panasonic mainboards TNPH1077, TNPH1100 , TNPH1120 and TNPH1111    ...

哈哈,翻译了才看得懂。这下被打脸了吧,在事实不明责任不清的情况下公然骂街,不是有修养的人所为!好在我们国人素养很高,没发现任何不当的言论。以前每天回帖,这下子几天都不冒泡,连一点承认错误的勇气也没有吗?是男人的话就认错道歉,古人云知错能改善莫大焉!

Greetings to your second uncle, don't bump into the south wall, don't look back, you can't write it. Just try another one, won't you? Besides, Toshiba EMMC version 4.5 has no life prompt, and it also says that there is no instrument to test EMMC to confirm that it is bad. The master is a quack, which is pure fart. China is full of miracle doctors, and experience is our means of inspection and maintenance! We need both quality and speed. This is China's speed! If you repair the machine this way, you can't repair one in 10 years. Uncle Deng once said, "seeking truth from facts and practice are the only standards for testing truth."

Dear comrades!
I need the correct eMMC dump software for the Panasonic TNPH1077 1A chassis to write ...

The technical forum is a platform for everyone to share and communicate. you insult us in the absence of clear responsibility, we will not care about it.Now it is clear that the problem is your own operation, you do not have the slightest apology in your words, but righteously asked us for the software.It is our responsibility to provide programmer technical support, but do not take it as our obligation to provide data and guide maintenance!We can give you the data for free, but your attitude is unaccep

Is it possible to read the boot,user area error?If so, the root cause is bad EMMC chips with bad channels.

Reading and writing these chip is not possible.

Can't identify emMC?Panasonic's machine protection circuit is relatively complete, can you upload the picture of your operation?Do you use local power or separate power supply?  Post time 2020-10-13 22:10

Dear Sir !
Thank you for your answer  !

My RT809H programmer recognizes this chip on automatic search as well as on manual selection as THGBMBG5D1KBAIL_ISP . However, when I try to write, the device currently says to wait and as soon as the writing of the chip starts, I get a program blockade that says WRITE ERROR OPERATION TERMINATED. Then the program table turns white and blocks and I get a message on the display to look for a solution to the problem on the internet. After searching the Internet, the program shuts down and restarts. When I start writing again I get the same result! I use separate power supply 3.3V from my service device? With other eMMC integrated circuit that are on the mainboards produced by Samsung and LG I have no problems. Only Panasonic mainboards TNPH1077, TNPH1100 , TNPH1120 and TNPH1111  make this problem ! Whu? I have good and proven Panasonic software that I need to write. Maybe this RT809H programmer can't do this programming? I am very disappointed in the RT809H and I think it is not a good device for ISP programming at all, as it is written in Chinese commercials? I made the mistake of buying it at all and I will pass on my bad experience with this device to all my colleagues. If you have the Email address of the constructor of this shit, I would like to kontaktieren with this sir  and convey my negative experience. Maybe he can help me?

Why not think backwards?Since the programmer can read and write to other types of machines, the proof is not a programmer problem.Considering the special design of the Panasonic machine, and THGBM5G5A1JBAIR does not support the life display, many chips have bad channels and cannot read the User area at all.

1.Only keep the USB data cable connected to the computer on the programmer for ‘SELFTEST’ of the programmer.
If there is a problem with the self-test, the MOS tube may be damaged due to the leakage of the soldering iron.

2.If SelfTest 0 test pass,Please strictly follow the points shown in the figure below to connect with the programmer.

3.The power supply of EMMC should not be drawn from the programmer. The power supply VCC and VCCQ of EMMC are supplied by an external power supply.

We have bought and tested the board according to the model you provided. Reading and writing are completely normal. Have you tested it? I asked you how to operate it from the beginning. I have never seen you provide any operation process. At the beginning, I also emphasized the particularity of Panasonic machine.
