    MacBook Pro Shut down after Bios Unlocked

    Macbook Pro Mid 2012 i5
    Model: A1287
    Mobo: 820-2565-A
    EMC: 2554
    Bios: MX25L6406E

    Using CH314A tried auto detect chip and it detected as MX25L6405D instead of MX25L6406E. Still i insist selecting MX25L6406E as i know the markings 100% indicated on chip.

    Programmed successfully, Verified Successfully, after installing back to the Motherboard. First it POWER ON for about a minute. while im trying to install fresh OS it suddenly shut down. I did SMC and NVRAM reset too, but still having this issue.

    Any help?

    You need to copy the old ME region into the new dump. (or at least use a clean ME dump)

    Also I guess you meant model A1278 for a 13" and board number 820-3115

      Thanks for reply, ohh a typo error, correction its A1278, but for board number its correct 820-2565-A.

      1.Downloaded here a 2554 - 13 MBP 2012 i5 2.5.bin (AFAIK posted by Polytek & it is clean,unlocked.)
      2.Copied my serial from my backup .bin also copied the hash C072
      3.Replaced the serial and hash of the .bin file i downloaded.

      Is this what you mean to say ME region? If not can you share here how to do it? And anybody can share clean ME dump?

      Thanks in advance

          ASUS TP500LA BIOS request/repair/merge?
          by jbonavita
          Hi, my laptop wont boot at all
          With original bios no POST, only LED lights
          With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
          Some issues
          A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
          B- If updated from 500LN version 203 to 300, the battery stops being recognized

          Things I tried

          1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
          by zenius
          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

          Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
          by Wahaz
          Hello,

          I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
          So I thought it was a Bios problem.
          I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

          HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
          by Bloodhoundje
          Hi everyone,

          I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

          I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

          After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

          I have desoldered the bios chip (GigaDevice...
