How to Downgrade BM622m - BM623m Package Date 2013

How to Downgrade BM622m - BM623m package date 2013

Lecture muna tayo :

Question: Bakit Gusto ng iba na downgraded yung modem nila?

Sagot : 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


Tips ko bago  mag DOWNGRADE UPGRADE ENABLE mo muna yung TELNET
(Enable Telnet First Before Downgrading)

Software Version :

Hindi porket  2013  yan para pareho na yan iba iba yung software version nyan.
Paano malalaman anong software version at packate date yung  modem.

Kung 622m user ka type mo 192.168.254.1 sa browser mo
This  what  you can find ..

Software version of Package Date 2012 is B016  (16) last 
Software version of Package Date 2013 are  B019 , B021, and B022

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

1. Press and Hold  reset button minimum of  1 to 2 minutes.
2. all lights up first
3. Observe the lights  blink sequence   similar on light  repeated sequence when uploading
4. 1 and 5  will lights  , then   2 and 4 last 3( repeated)
5. sometimes    1, 3, 5, 2,4  blink sequence.
6. all signal light turn of   while Power and LAN  are still on 
7. Hard RESET Finish

This What Happen If you DO NOT Follow the HARD RESET  Un proper IP config for firmware

Instead  622m IP it is  Mybro IP , Do a Hard Reset to Fix

Instead  of Mybro IP  it is a 623m IP ,Do a HARD RESET  to Fix

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 firmware  like Mybro   or GP firmware .
Do the step above.. then after success upload  GP or Mybro.. You can upload 622m Firmware B016 same step above gui or winspreader.

NOTE: Hard reset or signal light on Mybro sometimes only 1 and 2 are on.. 

Very important do the Hard Reset for every downgrade to upgrade.. Kumbaga sa pag rereformat ng computer eto yung final stage.. dahil di mag tatake effect yung new firmware settings pag di ka nag restore default..

Question:
Bakit ayaw mag upgrade  sa gui ng Mybro nag oopen lang yung Browse?
Huwag gamitin yung mouse sa pag select ng menu ..pag naka select kana ng firmware  gamitin ang TAB sa keyboard sa pag select ng upgrade makikita mo may  line_ _ _ _   sapligid ng upgrade/upload  Press mo Enter sa keyboard.. mag pro proceed   kana sa upgrading.. Tips ko mas maganda gamitin ang FireFox browser.

Bakit walang WiFi  noong naging Mybro or Gp yung firmware?
walang WiFi talga yung sa Mybro kaya dapat 622m yung firmware nyo talga dyan or balik nyo sa 623m..

Bakit di ako maka log in?
Baka di nyo pa ginawa yung Hard Reset  tapos na iwan pa yung setting ng previews firmware at kada palit ng firmware mag iiba talga user nyan after ng hard reset at upload ng firmware , may sample sa itaas  yung iba yung IP sa Firmware..


--Kung gusto nyo pasukin admin ng Mybro or GP try nyo mag change mac gamit yung mga scripts dito pang change mac kasama sa scripts yun.. 
after mag change mac gamit yung tools
