ABOUT MOBILE TECHNOLOGY
Martin Couper is called as the father of mobile phone.
Intro about h/w parts in Mobile phones:
Mobile is a h/w & electronic thing.
In mobile 2 types of tech.
1.GSM(Global System for Mobile Communicatn(old name-Groupe speciale mobile-1982))
2.CDMA(Code Division Multiple Access)
3.TDMA(Time Division Multiple Access)
In mobile 2 types of frequencies(range):
1.1800mhz
2.900mhz
In mobile 2 types of handsets:
1.Single band(900mhz)
2.Dual band(1800mhz)
GSM Codes:(for restoring & use this codes without inserting memory card)
1.china-1122,12345,0000
2.sony Ericcson-1234
3.Spice-1122,5678
4.Motorola-1234
5.Reliance classic-0000
6.Samsung-1234

8.Multimedia mobile-*#7780#,*#7370#
9.LG-0000
To convert other lang. in english:*#0044#,*#1234#
To cancel all divert calls:##002#
2) sizes of sim cards:
1.Credit card size
2.Stamp size
In h/w problem incomig & outgoing calls are always starts & on/off switch when we want to switch on then on
else off.
In s/w problem Mobile phone can not switch on.
Mobile parts:-
All handset within made in 20volts.battary 3.60.If mobile charge within 3.30-3.40 then mobile phone
can not switch on.
1)Motherboard(kit/PCB(Printed circuit board))
2)Mice-Our voice sound is not going at the end.
3)Speaker-We can not heard the voice.
4)Ringer-We can not heard the ringtone.
5)Vibrate-Can not vibrate.
6)Insert sim card-n/w switch.
7)Display-Soldering display,without strep display.
8)On off double switch.
9)On off rouber switch.
10)Charging sockets.
11)External & Inneral kpad.
12)Headphone sockets.2types-power supply & n/w junctn.
13)Battary connector.BGIC-Ball gray area.If IC damage then jump.
Use of Multimeter:-In it 20volt & buzzer(voice) is must used & used digit also.
20volts is used to check battary & charging.& Buzzer is used for motherboard connectn
check.Ex-Mice,Ringer,Speaker.
Types of batteries:-NIMH,NICD,LION(Lithum ION).
Use of batteries:-
To supply powet to mobile is used batteries.Battary vol s 3.6-3.7 & it havaing 3
terminals in that + & -
are available & other for to display identity on the screen like Battary is low & so on.
How to check battary:-
In multimeter 20 is the smallest digit.In battary chaecking process multimeter is kept in
20volts &
then multimeter + point attach to the battaries + point & - point to battaries - point & then on multimeter check
battary vol.
Battary vol minimum 3.60volt or 3.70volt.
Battary problem:-
1)Battary dead.
2)No charging.
Water damage problem:-Hardware is repaired by the PCB.smtaker used for hitting.
1)Battary connector check.
2)Battary kept outside the mobile.
3)If battary volt is low then give zap(zataka).
4)Open mobile.
5)All motherboard is clean by PCB cleaner.
6)Hot Air Gun is used for hit the motherboard.Maximum gold paste & then after reball if mobile fall in water.
7)Pack the mobile & check.
8)After packing the mobile is not switched on.then servicing more times.
9)check motherboard having any damage & dust in it.
10)BGIA-Ball gray area Max paste gold on BGIA & check by hot air gun.
12)At last mobile can not switched on then check by s/w.
MOBILE S/W:-
2 Types of mobile repairy
1)h/w
2)s/w
1)H/w :-
When we check mobile first checked by battary & then on motherboard various parts checked by
multimeter & if damaged
then rplace it is called "H/W repairy".
2)S/W :-
In it mobile phone is connected to the PC & then in mobile s/w thrown in the mobile or kept in mobile
is called
"S/W or computerized repairy".
Types of memory cards:-
1)MMC(Multimedia card)-7 clips
2)Mini micro SD(Secured data)-9 clips
3)M2(Only soni ericssion)or pro MSAC/MMC-10 clips
Mobile downloading:-
Songs,rigtone,wallpaper,games,images & applicatn are thrown to the another mobile is
called "Downloading".
Types of downloading:-
1)SMS/MMS
2)Infared
3)Bluetooth
4)Via computer
5)Internet
Types of mobile s/w repairy:-
1)Flashing
2)Unlocking
1)Flashing:-
Mobile connect to the PC & in that mobile flash files kept in that or loading is called is "Flashing".
When it do:-
1)Mobile hangs.
2)n/w problem.
3)Battary problem if not solved by h/w.
4 setup flashing(instruments):-
1)PC-p4
2)Flasher box
3)Flasher cable
4)Flasher s/w.
UFS-Universal flasher s/w.
JAF
Empty box.
Catty box.
2)Unlocking:-(UI setting)set full factory default
Locking:-
Unuse of mobile handset use lock code(password).If this passwd is forget or change then we
have to unlocking also for that purpose flasher box is used.
Nokia is from Finland,Europe.
Samsung-South Korea.
G-five-China.
