    The screenshot above as many of you are familiar with the board of Huawei Echolife BM622 this is the so-called WAN_IC, most the version of Huawei BM622 4G WiMAX broadband modem wireless router it uses ST Micro M25P32 (25P32V6G) 32Mbit, Low Voltage, Serial Flash Memory. Another version of this device gateway is using different chips but there is an alternative substitute/reference for Serial Flash Memory to those who are techie.

    To make life more easier on DIY repairing the BM622 "blank WAN" likewise the "tulala" issue there is no need for "Baklas Kabit" meaning no need for you to removed the WAN_IC and put it back again after re/flashing. Without taking off the chip is best to re/flash the WAN_IC to avoid damaging by using a "hot air".

    Here's few things I need:

    Take note for the soldering lid used here I have chosen the tiniest 0.3mm diameter because the thick one will not do the work well, you can find on the cellphone technician shop ask only for 1meter is enough.

    Tiny copper wire this will be used for jumpering the ST Micro M25P32 Serial Flash Memory or the WAN_IC, its 0.10mm diameter just like the strand of your hair. This is also a cellphone technician best friend you can ask for 1meter is enough.

    An alternative where you can get a tiny copper is from your busted cheap fluorescent lamp. When using a soldering iron a pointed tip is best to not mess with lid since M25P32 surrounded by tiny capacitor and resistor it might be damaged or may short circuited with other parts.

    The simplest programming/flashing the M25P32 Serial Flash Memory is to used the IC socket with tiny copper wires atleast two IC socket will do and a candle glue you can get this from eGizmo if you are in Manila or Alexan.

    My USB MiniPro TL866CS Universal Programmer I bought it from eBay, it can programmed of thousand of chips, read, write and re-flashed different types of eeprom, flash memory, etc.

    The BlackcatUSB can also read, write and re-flashed but only limited chips unlike the TL866 can do thousands. The good thing about this programmer device is that you can use it as JTAGging also bought from eBay.

    This is not the least option or alternative for repairing the Huawei Echolife BM622 4G WiMAX broadband wireless modem router blank WAN likewise for "tulala". The cheapest for about less than 50pesos or FREE hardware for flashing the M25P32 is the LPT a homemade flasher. It is slower when programming if compared to the above two USB programmer/flasher

    AEOLUS rework station is just an option if you prepare the "baklas kabit", removing and putting it back from the board of the Echolife BM622 the ST Micro M25P32 Serial Flash Memory is really so tricky because you might burned it by using the "hot air" improperly.
