    Advice on newer EC chip programming eg. MEC5107-LJ BGA

    Hey all, was wanting to know what cheapest option is for programming EC chips such as the MEC5107-LJ

    i searched online and found such programmers as the SVOD4, Vertyanov Successor , and the RT809h type but didn’t see this particular BGA EC chips listed? So hoping for some advice here , cheers.

      ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
      by DynaxSC
      Hi

      I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
      The SPI chip is an Winbond 25Q256JWEQ model (1V8).
      The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
      The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

      I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

      A: If you can`t read from it how do you expect to write to it ?.

      Q: Why is my bios chip unreadable ?.

      A: The programmer is faulty or has a worn or broken zif socket.

      The USB cable is frayed,connector pins worn or some other physical damage.

      Not enough amperage or voltage to power the programmer properly.

      ITE IT8390 (IT8390E-256) programmer "ITE Download Board 4" user manual + firmware, flashing ITE ECs on the cheap
      by H34TO
      Recently I've gotten into EC flashing due to my broken laptop(s) and started frantically searching methods for flashing the IT5571E-128 chip on the cheap(due to me beaing a student and not having a job) and noticed that ITE newer chips can be flashed via ISP (In-System Programming) either via SMBus or the KBC (EPP - Enhanced Parallel Port) interface. While these can be achieved with programmers like SVOD4/3 or the RT809H/F those options are WAYYY out of my budget so I was horrified. But recently I stumbled uppon some programmers on aliexpress that claim they can program a variety of ITE chips...

      Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
      by acedogblast
      This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

      There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

      ASUS Zenbook Pro Duo UX8402ZA BIOS
      by pirati
      Hello everyone,

      I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

      When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

      I decided to try flashing a new BIOS, but since I didn’t want to desolder...
