Huawei BM622m Best NAND Flasher Programmer

As we all know the new BM622m is the replacement of the legacy Huawei Echolife BM622 and BM622i 4G WiMAX wireless broadband modem router. This new device have more advantages than those two old model wireless residential gateway. Taking a look on the hardware of the BM622m it is equip with a NAND flash memory HYNIX HY27US08561A  using TSOP48 package unlike BM622 built with NOR flash memory such as Spansion S29GL064 or STMicro M29W640 likewise same 48pins. 

The hardest part of BM622m is the reverse engineering, if you wanted to dump the flash memory into a raw file of this CPE its not as easy as that of BM622 and BM622i unit were MiniPro TL866CS programmer won't support for dumping it.

One of the best NAND programmer I have found on the net is the Flash Doctor, in contrast to MiniPro TL866CS  programmer that support more than 11 thousand of Chips except for NAND flash memory.

Flash Doctor supports all NAND-based flash storage devices (SD, SM, MMC, XD, USB Pendrive, MemoryStick, CompactFlash etc.), with damaged controller or any other front ends (PCB, etc.) since Flash Data Recovery Doctor needs to work on the flash memory only when users carry out Flash Data Recovery.

Hopefully this article will help my avid reader and commenter who has been longing for their BM622m to dump the firmware to be able for them to downgrade their WiMAX CPE.
