Pening nak root handphone? jangan risau, sini aku nak share cara cara untuk root handphone jenis samsung galaxy s2 GT-i9100G yang running kat OS Jelly Bean, ya GT-i9100G saja. Mudah saja cara nya, sebelum tu pastikan handphone anda fully charged.

Arahan:
1. Download SU-BB-Installer kat sini
2. lepas download simpan zip file tu kat external SD Card
3. OFF handphone anda
4. boot masuk kedalam recovery mode butang volume up + home + power
5. arahkan ke "apply update from external storage" menggunakan volume up / down
6. pilih dengan menekan butang power
7. pilih file "BB-SU-Installer.zip" tadi dan tekan butang power
8. tunggu sehingga habis dan navigate ke atas.
9. pilih "reboot system now"
10. tahniah anda telah berjaya root dan busybox hp anda.

tambahan(JB sahaja):
Untuk mendapatkan CWM recovery, jikalau lain kali anda nak install custom rom,
1. download mana mana satu stock recovery flashable zips daripada Blazing Safe Kernel di sini
2. simpan kat SD card.
2. OFF handphone
3.boot masuk kedalam recovery mode butang volume up + home + power
4. arahkan ke "apply update from external storage" menggunakan volume up / down
5. pilih dengan menekan butang power
6. tunggu sehingga selesai dan navigate ke atas
7. pilih "reboot system now"
8. tahniah anda telah berjaya menukar ke CWM recovery, boot dengan vol up + home + power untuk mengujinya.

Telekom Malaysia fiber optic loss data calculation formula

ACCESS/TRANSMISSION LOSS DATA CALCULATION

=aL+bN+C 

@ 

= (cable loss x cable lenght) + (average loss x no. of splice) + connector loss

a=cable loss, 0.4 for 1310nm & 0.24 for 1550nm.

b=average loss, 0.15db for 1310nm & 0.1db for 1550nm.

C=Connector loss (0.5db per connector).

L=cable length.

N=Number of splice.(Joint)

HSBB LOSS DATA CALCULATION

Total Loss = (cable loss x cable distance) + (splice loss x no.of.joint) + connector

Cable Loss

-         1310nm = < 0.35dB/km

-         1550nm = < 0.21dB/km

Splice Loss = < 0.05dB

Connector Loss = < 0.2dB

Kilo Bytes Per Second vs. Kilo Bits Per Second (KBps vs. kbps)

Measure of file size: KBps
File size i.e. how big the file or how much space a file occupies in the hard disk measured in terms of KiloBytes (KB upper case “K” and upper case “B”). In computing terms the upper case “K” stands for 1024. 1024 is computed from 210. (2 power 10). 2 denote the number of characters in the binary system which is used to store data in the disc (ones and zeroes).
Other abbreviations like mega, giga and terra also use the base as 1024,

1KB (KiloByte) = 1024 Bytes (approximately 1000 Bytes)
1MB (MegaByte) = 1024 KB (approximately 1000 KiloBytes or 1 million Bytes)
1GB (GigaByte) = 1024 MB (approximately 1000 MegaBytes or 1 billion Bytes)
1TB (TerraByte) = 1024 GB (approximately 1000 GigaBytes or 1 trillion Bytes)

Measure of data transfer speeds: kbps
Data transfer speed over the networks (including the internet) is calculated in terms of bits per second: kilobits (kb small case “k” and small case “b”). The higher the kbps i.e. more the bits transferred per second, more the speed, faster the network/connection. Here k stands for 1000 (103 )

1 kbps (kilo bits per second) = 1000 bits per second
1 Mbps (mega bits per second) = 1000 kilo bits per second.
1 Gbps (giga bits per second) = 1,000 mega bits per second.

ISP bandwidth and download speeds
The most common confusion caused by the similarity of KBps and kbps is when it comes to internet bandwidth and download speeds. People often complain that their ISP promised 512kbps connectivity but they are seldom able to download any file at 512 KBps. They fail to notice the difference in cases of the units and hence think their ISP is cheating them or offering them poor quality service. As mentioned earlier data transfer speeds are always calculated in terms of kilo bits per second (kbps) so an ISP connectivity of 512 kbps promises of transfer of at the max 512 kilo bits per second.

On the other hand, file size measure is always in Kilo Bytes and thus download speeds are always calculated based on how many Bytes per second are downloaded and hence Kilo Bytes per second (KBps). KBps and kbps are not interchangeable.

So an internet connectivity of say 512kbps can never achieve a download speed of 512 KBps. To calculate the maximum download speed of a “X kbps” connection, we need to use a simple formula as below.

Download KBPS speed = (Kbps value*1000) /8)) / 1024.

I.e. For a connectivity of 512 kbps

kbps value * 1000 = 512 * 1000 = 512000

512000 / 8 = 64000

64000 / 1024 = 62.5 KBps

Therefore theoretically an internet connection of 512kbps bandwidth can download at a speed of 62.5 KBps

If you don’t want to go through all the hassles of the above formula, just multiply the kbps value with 0.1220703125 to get the KBps value.

512 kbps * 0.1220703125 = 62.5 KBps. Simple!

Internet Connectivity	Download speed (approx)
256 kbps	31.3 KBps
384 kbps	46.9 KBps
512 kbps	62.5 KBps
768 kbps	93.8 KBps
1024 kbps	122.1 KBps

I have mentioned download speed as approximate because they will vary (always reduce) by 15 – 20% due to network signal loss, computer hardware overheads etc. So for realistic, real world figures always reduce 15 – 20% from the computed KBPS download speeds

Now I guess the confusion of kbps and KBps has cleared away. Just remember when you talk in terms of network it’s always bits per second (bps) and when you talk in terms of storage and files its always Bytes per second (Bps). And next time you won’t complain when your 512 kbps connection does not give you download speeds of 512KBps because now you know why.
