Actually, you could find many sites which already explained how to unlock a Mobily 4G router. However I feel that there are missing information on those sites, so I will try to explain on my own way.

Long story short

I bought the router 2nd hand from expatriates. And of course before choosing this router I already searched in the Internet that we could unlock this router or not. At the beginning I am using the router locked/default, and after 2 months, with my Mobily data plan is about to finish, and due to its service is very bad, my plan is to switch to Zain. FYI, I have tried all these three service providers (STC, ZAIN and Mobily) and in my opinion Zain has the best service – internet plan. I wish I could switch also my prepaid voice, but my mobile number is already everywhere.

  • I wrote this article using the unlocked router 🙂


  • I found out that the firmware is very unstable, after 1-2 days, my router came to boot loop and I have to disassemble it. Even I had disassembled it, and removed the GSM module as some article said, it did not fix the problem. (more…)

My Final Thesis

Tomorrow I’ll return to my country. I’ve been here (korea) for 2 years and 3 months. I underwent good and also hard time here, and Alhamdulillah, gladly I could pass them all. Here is a small video what I did for almost 2 years work:

I’d like to thank for everyone who has helped me during my stay in Korea.

The details are on my thesis, please note that the data is in preliminary test.

Old memory :)

Old memory, I learned assembly first time when I were in Senior High School, 2nd grade. I learned how to write a .com program using debug. And now, after several struggle I managed to dig in my brain and wrote the tiny program 🙂

-A 100
0B32:0100 MOV AH,02
0B32:0102 MOV DL,41
0B32:0104 MOV CL,1A
0B32:0106 INT 21
0B32:0108 INC DL
0B32:010A LOOP 106
0B32:010C INT 20H
CX 0000
Writing 0000E bytes
Program terminated normally

Volume in drive C is WINDOWS
Volume Serial Number is C012-9F20

Directory of C:\

09/10/2007 06:12 PM 14 ABC.COM
1 File(s) 14 bytes
0 Dir(s) 11,225,669,632 bytes free


I cannot remember which service interrupt used to put a single character into screen, well, here’s the reference:

Category: DOS kernel


	AH = 02h
	DL = character to write
Return: AL = last character output (despite the official docs which state
		nothing is returned) (at least DOS 2.1-7.0)
Notes:	^C/^Break are checked, and INT 23 executed if pressed
	standard output is always the screen under DOS 1.x, but may be
	  redirected under DOS 2+
	the last character output will be the character in DL unless DL=09h
	  on entry, in which case AL=20h as tabs are expanded to blanks
	if standard output is redirected to a file, no error checks (write-
	  protected, full media, etc.) are performed
SeeAlso: AH=06h,AH=09h

~Still remembering the first time I cracked a commercial software =P, lol, it was fun. Thx for the tutorial writer, sorry I forgot your name =D
