The semi finished product of cell phone jammer

I removed the two filters to get the capacitor connected across the no signal and then reinstall the CPU does not work, and again asked the guests is normally used in case of no signal, if that is normally used in case of no signal then the hardware should be no any questions that write software test it to the network under disassemble software rewrite installed on a test OK signal. Telsda T608 + signal, the machine have not been revised to keep up with a current almost terminated a copper wire or no signal after the filter in the 900M, the machine is no signal of the machine under normal repair, write software test about , and later when I press * # 06 # to find the serial number is 0000000000000000, and more want to write software to try. System of completely personal responsibility is performed to    cell phone jammer .
The demolition of the font to the East China Sea 72 backup detection font has short-circuit or model, does not back together who knows a signal * # 06 # IMEI or ignore it anyway, a signal on the line. Later remembered a friend said he said he repaired one of these machines font dilute welding can also cause no signal MT column machine. It seems there is always the case. These two cases we have. MT chip series machine handset silent change headphones First, check the headset voltage with or without 1.2V short Headset 2.4 feet. 3-foot fly line from the headset to a handset. MTK series microarrays boot screen [2] now the MTK Ruipian the machine, some machines you do not have the software. Only the signal in the specific area can be shielded by   cell phone jammers .
To the machine or boot to set the screen, or sometimes given version, and a mess of software failure, if you do not have the software you can use MTK48 programmer unlock method of repair of machinery, very simple, MTK unlock the address of friends should know, 4M, 8M, 16M, and so on. This repair method is to update the chip data, in general, the software under normal use conditions, are caused by the chip failure, so we adopt this solution to a fault caused by the chip data, this address to clear into the FF, then put it back pressing power chip data will re-establish, so that does not resolve? Placing position of     cellphone jammer should be correctly chosen to avoid the shielding dead zone.
But when you write the software to back up in case of bad with the fixed version when to have it fixed, can not make it not open, so back up, this CPU feature is very powerful, fault, one of the most common a boot low battery, then shut down. This failure causes the CPU battery detection feet do not get the battery data, that is the power of the CPU pick the measured foot to the battery + problem, and they are mostly connected by an exclusion (1004) , exclusion deterioration or false welding causes up to bad, the CPU board break. 6205 the power to pick up the measuring pin D6, A6 (charge capacity pick test) 6217,6218,6219 the power to pick the measured foot the D6, C6 (charge capacity pick test)]. The place of origin of   phone jammer is Guangdong.
MP3 phones sound classic kill failure all the head ringing amplifier Weld, a long time listening to music, the amplifier fever caused by Weld. The amplifier is very small glass film welding time to pay attention, remember the direction of the IC and the high temperature should be removed and then remove the plastic and then welding. MT series emission shutdown solutions to launch the shutdown, the first power source tone 4. 5V or so, try to see the launch will not shut shutdown if the shutdown, bad amplifier. If you do not shut down, the amplifier is not bad, personally think that should still be IF and CPU (personal meaning). The output of antenna of  cell phone jammer can be adjusted from 0 Watt to 3Watt for each antenna.
