Some quote from refference
Means they didn`t use vga connector but succeed in flashing weltrend?5. Working with the program (postal2.rar) is shown on the video
only we do not use VGA-connector
For example UE40F6650ABXKZ:
For example on BN41-02148A BN94-08039S (UE22H5600..., same goes for F5500 and maybe some other...) it is IC1304.
No wp pin is needed. As you see programmer has some communication via IC2 line and turns micom in to isp programming mode by sending some consequence of bytes. possible to get weltrend properly flashed, you have to chose different version of chip in programmer OR strip empty code from dump before to flash (coz size differences).
If you flash 65Kbytes to 48Kbytes chip (e.g. 805...) then you always get procedure failuer and get crc mismatch.juusso wrote: Important, that WT61P805, which we have on most B to F series TV`s ( while WT61P8 is used on LG, Philips some Toshibas and maybe other) has reduced internal SPI flash size (48Kb) and before to flash, dump must be reduced (removing empty code) to adjust size. Else flashing error occurs w/o chance to reflash firmware.
