Tutorial on How to Downgrade BM622m BM623m Package Date 2013
Question: Bakit Gusto ng iba na downgraded yung modem nila?
Answer: kasi yung package date 2013 yung mga firmware ( software version) nila ay naka fix at uncheckable yung LAN Telnet at SSH , pag 2012 na firmware madali mag change at gamitin pang HUNT - SNIPE dahil pwede i check yung box ng telnet.
Vulnerability : pag tanga yung user aksidente nya ma checheck yung WAN , at naka default yung user pass ng admin pwede generate yung Serial at WAN Mac
Kung ako tatanungin kung di nyo naman pang ssnipe yan mas ok pa ako sa 2013 mas ok firewall nyan
Ganito yung 622m 623m 2013 unchekable yung box ng LAN Telnet/SSH kaya need natin ng webdeveloper pang check ng box or old school inspect element to enable the checkbox lagi ganun yan pag 2013 lagi mo check muna click apply bago mag change mac ulit

Observing Signal Lights while Uploading Firmware :Very Important
You should observe the signal light blink sequence when uploading firmware
When the uploading start signal light blink like a charging battery on your phone
SLOWMO Sequence from 1 , 2 , 3 ,4 ,5 or 1 and 5 , 2 and 4,
If the signal light are steady , usually it stop at 1 and 2 or 3 signal lights are ON Uploading Firmware is Finish..
NOTE: Failed Upload Firmware Signal Sequence is too FAST!! 12345 - 12345
Meaning Firmware upload Failed
HARD RESET : Very Important
Take note this for every success upload firmware Please DO a Hard RESET
- Press and Hold reset button minimum of 1 to 2 minutes.
- all lights up first
- Observe the lights blink sequence similar on light repeated sequence when uploading
- 1 and 5 will lights , then 2 and 4 last 3( repeated)
- sometimes 1, 3, 5, 2,4 blink sequence.
- all signal light turn of while Power and LAN are still on
- Hard RESET Finish
This What Happen If you DO NOT Fallow the HARD RESET Un proper IP config for firmware
Instead 622m IP it is Mybro IP
Instead of Mybro IP it is a 623m IP
WHAT IF FIRMWARE UPLOAD FAILED?
This is a very common firmware upload failed because the present firmware is too big and there is no enough space to re upload new firmware and extract it to the mediatek chip.SOLUTION: upload a low space like Mybro or GP firmware then upload your desired 2012 Firmware B016.
