Legacy Huawei Echolife BM622 4G WiMAX Modem Router Endless Life

The Huawei Echolife BM622 4G WiMAX broadband modem router is a legacy wireless residential gateway CPE manufactured by Huawei Technologies for Globe Telecom ISP in the Philippines.  The BM622 device is still popular until to date although this device has been already ended its life by the makers likewise the supplier has no longer issuing for their new user on internet wireless broadband subscriber.

It is astonishing for this legacy CPE the BM622 without any technical support by the Huawei Technologies and likewise the Globe Telecom ISP it can still be up and running. As a repairman like me I have reviewed this bulky 4G WiMAX broadband wireless modem router that even for a less techie person this equipment is handful to be fix, servicing this unit is not as difficult if compared to other SOHO gateways.

In addition to that, there are so many pdf and html file format tutorial that can be download with help of Google search engine to locate this manual. Forumers also did their part making step-by-step guide on how-to fix/repair this device, not only that but they have also provide a chat for interaction such Facebook on how-to Do-It-Yourself (DIY) for the homemade hardware flasher kit.

Even myself I have contributed the cross-reference Chips/IC for easy substitution of none local availability of ST Micro M25P32 4Mbit Serial Flash Memory likewise for the Spansion S29GL064 64Mbit NOR Flash Memory of this legacy residential wireless broadband modem router.

Huawei Echolife BM622 repair blank WAN easily

This article is supposed and not only intended to jEnNrhANz comment on my previous post Huawei BM622 Blank WAN Solved! but also to other netizen who is facing similar problem on having hard time solving the blank WAN issue likewise for the "tulala" this will help their life more easier.

Snapshot taken by Canon Rebel T3 using macro lens

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.

EZoFlash+ installation guide.

1.) Power supply output voltage +15…+18V, max current 300mA or more. Be sure , power supply connector internal positiv ! Recommended power supply with stabilised output voltage.

Check filtered non-stabilised power supply output voltage drop, load shortly power supply connector with resistor about 150 Ohm (load 100-120mA). Output voltage schould remain in recommended voltage range. Expect EPROM adapters use, check power supply voltage with resistor about 47 Ohm (load 300-350mA).

DC Power Jack and Plug are available with internal pin diameter 2.1mm or 2.5mm. Adapt both connectors for the same size.

Be sure on power supply isolated output voltage, no static voltage between power supply connector and computer grounds.

2.) Programmer EZoFlash+ default jumpers are Jp1, Jp3, Jp5.

Programmer logic IC and target chip have +5V voltage, A18 used on connector BU3.

Change jumper Jp5 (A18) to Jp4 (RST/Vpp) for BU3 based adapters only where Vpp or RST required , read settings in adapters page.

Change jumpers Jp1, Jp3 (+5V) to Jp2 (programmer +4.3V, target chip +3.6V) for low voltage (2.7-3.6V) target memory chip.

Change jumpers Jp1, Jp3 (+5V) to Jp2, Jp3 (+4.3V) for FWH/LPC adapters.

Other voltage options are available, for example all jumpers Jp1..Jp3 removed – programmer +3.6V, target chip +2.95V.

3.) Required adapter for target chip find in EZoFlash adapters page. Details and settings find on selected adapter page.

Corresponding flash memory and FWH/LPC chip adapter can be found in chip database.

Common jumpers on adapters – Jp7 (Vpp=Vcc), Jp8 (Vpp=+12V)

Extra adapter – voltage converter dc2dc_a4 is used with EPROM adapters to have higher programming voltages (Vcc=+5.7V , +6.2V ; Vpp= +12.5V…+13.2V, +21V, +25V)

Crossadapter prot_a1 is used for 8-bit flash memory adapters to provide sector lock/unlock in high voltage autoselect mode.

Verified chips, used adapters and test results are summarized in chip_test file.

4.) EZoFlash+ programmer works with Willem group programmer software in main PC OS , Windows XP and Windows 98SE preferably. Recommended latest software version 0.97ja. Sometimes useful are old versions 0.97g and 0.94a .

Software versions 0.98b, 0.98c, 0.98dx (0.98d2,.. 0.98d5) are not EZoFlash+ compatible.

Have a file setup97ja.exe, run it and follow to guide. Directory EPROM3 with files EpromM51.exe and io.dll will be created in Program Files. Uninstall option , Shortcuts in Desktop and Programs Menu are available.

Have a package with files EpromM51.exe (10.06.2004, 0.97ja ) and io.dll, unzip it and place both files in the same directory.

Have a package with files EpromM51.exe (26.01.2003, 0.97g or 21.02.2004, 0.94a) , dlportio.sys, dlportio.dll , unzip it and place all files in the same directory.
