hi, everyone
I have toshiba Encore WT8-A (PDW09C-00101L) windows tablet. And it shutdown every 30 minutes. I find this forum that someone can help me especially @plutomaniac this guy.
I am stuck. I attached necessary files. I can perform pin-mod methot. But what I am going to do after that. audio chip part number ALC5642

unfortunately I have no a programmer and I cant have it. my txe is really corrupted? I cant even upgrade bios. I got an errror. what we gonna do now

ok then. I have winbond 25Q64FWSIG bios chip. Which programmer do I need to flash it. Do I need it unsolder

if I get the programmer, Can we unlock the FD or can we solve the shutting problem. @Lost_N_BIOS @plutomaniac

25Q64FWSIG will need a 1.8V adapter to work with CH341A programmer.
I have the CH341A, TL866CS and SVOD3 programmers. Only SVOD3 doesn't need adapters.

Yes, you need CH341A + SOIC8 Test clip w/ Cable + 1.8V adapter. No soldering is required. All very cheap if you order from China and wait 3-5 weeks, if you need it fast then price will double or triple from local sellers or other places that ship faster
Here is general examples so you know what you are needing to purchase, you can get kits or combos on ebay that have all this in one listing too.

https://www.ebay.com/itm/382486015977 << On this, with other non-kit/combo listings, be careful and make sure listing says comes with cable, some listings will be selling clip only but show cable too in their images.

Yes, FD can be unlocked and ME FW fixed in few minutes with programmer.
When it arrives, slow down, wait for help/advice, just be sure you do not erase or write to chip until you've made a backup and had someone check it to confirm it's good, otherwise you can loose your board specific info like serial, UUID, LAN MAC ID etc.
When it arrives I can help you as needed. Here is general software and main driver - http://s000.tinyupload.com/index.php?fil...257455007472602

And here is how to use guide, this does not have adapter shown in it, I'll have to see if he can update with adapter info too if he has (PM Sent).
Basically, you will put adapter into programmer the same way you would a cable or chip, then your cable will go into adapter on top
[GUIDE] Flash BIOS with CH341A programmer
https://www.bios-mods.com/forum/Thread-G...341A-programmer << Same as one directly above, but with all images expanded/visible at once

Main thing to do once you have it working and detecting you chip is to get a backup made, upload that for someone to check, then wait and do not try to move forward until someone says OK GO

hello again. I got programmer and clips but not 1.8V adapter. Do I really need the adapter. Do we need this adaptor because of not de-soldering the chip from MB. İf so, I can remove it completely or just VCC and Gnd pin

Yes, you need 1.8V adapter as mentioned above. Chip can survive 3.3V usually, unsure for how long, but I do know data is corrupted on read and write always when this is attempted, if/when it does detect the chip and allow it, so you really have to get the adapter.

If you do know how to safely do lead free desoldering, then you could remove that chip and replace it with another same sized one you have spare or from a dead board.
If you are not familiar with lead free desoldering and do not have a good soldering station setup (ie not a cheap solder pen without high wattage and temp control) then it's best you don't do this because you can easily damage the board by destroying a pad or lifting a pad trying to get it hot enough to release.
You'd also probably damage the chip legs, during all this, if you are not familiar with removing such items put on with lead free solder, it's hard to keep them all hot enough at once to lift without trashing the legs.
Same applies with hot air, less chance you'd damage a pad by lifting it off due to too much heat for too long, but you can still damage pads or traces trying to do this if not familiar too.

Either way (solder or hot air), if you try it, in order to put on a different chip, please add lots more leaded solder first and plenty of flux, it will help release the lead free solder.
Tough to explain, and I probably shouldn't give advice like that without a huge guide explaining how all that works, but I know some people jump right in anyway so I wanted to give you some info to help release it if you tried.
At least that way if you jump, maybe knowing that will help you lessen chances of ripping the pads off the board due to being too cold or you think it's hot enough it should release and you try to force.
Lots more leaded solder And flux will get things flowing, but you do need a good high wattage solder setup or the board will suck all the heat right out of your solder tip and point of contact will never heat up to proper temps to release anything.

Best to use another system until your adapter arrives!

Hello again,
I got 1.8v adaptor. But how we combine all these. 1.8V adaptor socket pins are the same with CH341A programmer? I connect them like this. Is that correct? then what we do next? @plutomaniac, @Lost_N_BIOS

I couldnt wait and I connect the device and clips after remove the tablet's battery. I performed this link steps to PART 3 ([GUIDE] Flash BIOS with CH341A programmer) Here is my chip program picture and bios.bin file.
