          Hello thnx for reply , i should update the case.....

          ive seen there is a difference between that 2 Mmc, one is 8 the other 64GB

          I have now another problem, when i desolder the JY995 (8GB MMC) and try to backup it with the RT809H programmer the software and partitions on the JY995 are destroyed and i cant make a backup(see pic 1).....

          Normally the software is linux based and there should be some partitions like on (pic 2)


          Can somebody tell me another option without killing the mmc ?

              From datasheet i read that these mmc-s are the same size, only difference is different flash type and controller - but this is only internal difference.
              Some background info, what device, what was the initial problem you are trying to solve.

                      Backlight strip quality, Amazon vs Ebay vs ShopJimmy. Is there really a difference?
                      by DXseekerMO
                      Hello everyone!

                      Recently I've noticed that some ShopJimmy backlight strips don't have double-sided tape installed upon them when an application calls for it, and I must purchase the tape separately. In a recent chat conversation with a customer service agent I told them if this tape wasn't applied when it was called for I would begin to consider ordering my backlight strips elsewhere. It looks like this time may have come.

                      I recently got a TCL 65S4 with bad backlights. After looking at the SJ listing here: https://www.shopjimmy.com/tcl-jl-d65...365as-m-led-ba...

                      Is there a difference between PS4 Pro hdmi ports and PS5?
                      by survivalbloke
                      They look the same to me. I was just wondering if there is a difference between these.

                      For BGA reflow experts...
                      by Davi.p
                      I have attempted all sumed very few reflow processes, and i need to make it better, how do you make yours to have sureness that the balls are really fully reflowed? My temptation was always to do "the slight move" touching very gently an angle, but due to some cases, but maybe 100%, where the previously half working device became totally shut off, i finally understood that the damn "move" makes the balls shorted, so what do you suggest?
                      Thanks!.. Muchas gracias.....

                      Yahama mixer PSU difference
                      by Thermaltake
                      I am planning to buy myself a new mixer. Yamaha MG12U or XU(not sure) and I always like to take a look inside of mixer to check how it looks, if caps are low quality and other stuff.
                      I manage to find some teardown video on youtube but video name is saying MG12XU, but when you look at video on mixer it's MG12U.
                      And when I google those two models they have different PSUs one have cheap low quality caps, and other is way better with quality ones Nichicon. So I am confused now from what model exactly is that better PSU??
                      I google a little and found that there is this part number...

                      HP Envy 13-BA1565na BIOS for potential fix!
                      by themosttogain
                      Bit of a weird one here...I have this HP Envy which has an odd fault. Basically the power button doesn't turn the device on. However, immediately after a BIOS reset, it will turn on from battery once, and it'll continue to tun on from mains quite happily, first time every time for a few hours (but will not power on from battery at all). After a few hours, the button will become increasingly unresponsive again even with mains connected. I've replaced the battery, even though there were no signs of a battery problem, and the issue remains. From reading another post on here, the experts were...
