Huawei Echolife BM622 JTAG Serial Pinout

Today I have found the easy, best and simple way on How-To repair the Huawei Echolife 4G WiMAX CPE broadband wireless modem router being so-called firmware destroyer or FWD most of the times it is also referred as "bricked". On the other hand, Blank WAN is totally different you can navigate to the graphical user interface (gui) except your WAN intferface MAC address is BLANK and therefore techie labeled it as "blank WAN" this also can happen to the CPE. With this recent release of JTAG and Serial pinout there would be no more "Baklas Kabit" DIY hopefully.


The JTAG pinout must be tested first not with analog or digital multimeter because it will not do the work, eGizmo PIC18F2550 Pinguino is Andruino clone board can do the task on Boundary Scanning for absolute reading with open source apps.

# karating lng ng Arduino ATmega ko galing sa eBay, hopefully mascan na din ang JTAG & Serial pinout ng BM622 & BM622 at iba pang mga units.
