8GB Flash Drive Repaired

A very close friend, brought to me a Flash 8 Giga Bytes, crying, which had lost all data in it. I tested the flash drive by connecting it to the Laptop and it gave no sign of life, that is, not detected and nothing lit.

I opened it to check at the internal level and encountered that the end of the USB (Universal Serial Bus) pins were broken.

I had to think of a solution in order to help my friend. Then, an idea came that was to check the pin out from Flash with a broken Mouse cable, doing comparison:

To finalize and give a good finish, I used glue stick to seal and the Flash has been operational since June 2015. Take a look at the photo below:

    Hi Jaime, Nice repair but I'm afraid that it will break again in future on the spot were you glued the parts together.

    By-the-way: The Phison chip on your repaired Memory stick spec can be found on this Link:

    The PS2251-33 is a microcontroller that supports 3.3 and 1.8 Volt Flash I/O SLC (Single level cell) 2k to 8k-page large block NAND Flash.
    And can even be Firmware upgraded and works on 12MHz.

    I have a lot of USB Memory Sticks with different Controllers that do not work anymore so I made a sport to examine these if I can repair them by replacing components that are interchangable. But in fact the Controllers are mostly never the same. So I keep saving them until components do.

      Hi Humberto. There is no secret. Just use Google to find any info you seek on any hardware you have. I never have updated any USB memory Flash Nand stick before but read this fact in several datasheets of the USB Controllers on those Memory sticks. I don't know why you specifically are asking this question? But if I can help you with finding some info I will!

    Good job done and very innovative.
    Its not for long term use, maybe Albert alright but the data are saved to a new storage I hope so... 🙂
    That is the most important in a case like this.
    My best regards.
