JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs and testing printed circuit boards after manufacture.
JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. It specifies the use of a dedicated debug port implementing a serial communications interface for low-overhead access without requiring direct external access to the system address and data buses. The interface connects to an on-chip Test Access Port (TAP) that implements a stateful protocol to access a set of test registers that present chip logic levels and device capabilities of various parts.
The Joint Test Action Group formed in 1985 to develop a method of verifying designs and testing printed circuit boards after manufacture. In 1990 the Institute of Electrical and Electronics Engineers codified the results of the effort in IEEE Standard 1149.1-1990, entitled Standard Test Access Port and Boundary-Scan Architecture.
The JTAG standards have been extended by many semiconductor chip manufacturers with specialized variants to provide vendor-specific features.

Saan po nakakabili ng board ng j2prime?
Na deadboot kasi ang j2prime ko
Or kung may tech. Dito pa mention naman po kung magaling sa jtag. Pampanga at tarlac area po ako
Hello goodeve. Sino dito marunong mag JTAG method?
Nasira kasi Phone ko j2prime na dead on the spot (deadboot)
Pa mention nalang po kung may kakilala kang Technicians.
Handa akong mag bayad :)
guys alam nyo ba kung pano yung jtag sa cellphone? yung sakin kasi vibrate nalang talagang walang logo. sabi jtag daw kailangan. ano po ba yung jtag? may papalitan po bang pyesa dun? or parang reprogram po sya? kung magpaparepair po ba ko sa service center magkano po kaya aabutin?. thanks po
Mga boss, sino po ba dito marunong mag JTAG ng LG G3 sabi kasi ng technician na kilala ko eh kelangan na daw JTAG kasi di na bumubukas. wala daw sya gamit pang JTAG .. ask ko na din kung magkano magpa JTAG
hello po mga ka phc newbie lng po ako pagdating sa firmwire and other software related issues ng phone.
baka po may makatulong sa secondhand samsung j7 ko nabili ko lang po siya sa online buy and sell 2 days after kong mabili bigla nalang siyang namatay. di naman po siya nabagsak or nabasa sabi...
balak ko sana gawin yung sa tutorial to debug bm622m 2012 baka marepair ko. log-in using putty.exe tapos parang nasa linux nako then reset config. i will use CA-42 cable ng old nokia phones to connect to jtag. may pics naman dun sa tutorial kung pano i-connect eh.
