lighting tricks x1-01
Greetings,,,, boss,,,, good night all,,,, just got home from work, in fact my body is not strong anymore,,, because I'm really tired and sleepy,,, going to bed but I think less complete when straight to bed,,, hmmmm I finally push the phone,,, happened before the time at work I can be the case of mobile x1-01 that died in total, first I check the software first,,,, the main usual stance,,,, hehehe,,,, smile a little boss, let me not sleepy,,, after the check and re-check, it turns SW safe,,, there are only some of the tests fail, the usual line lcd problem, after I check one by one, there was a path-breaking one, after I jumper broken phone can flame, but the lights went out, then I check again led his path was still good, it turns out the problem is the diode damaged her, would be replaced but would be where the diode???Finally, turn the brain looked for on google about lighting trick jumper X1-01 the result was minimal, there is one trick but it is not clear.

contact service solution
Hmmm,,,,, wahyu appeared again,,, greetings ukhwah everything, hopefully the boss of all the current health and fortune amen,,,,, on the 3rd post I will discuss issues that no3 phone on my first post, the contact service
Why can contact mobile phone service?
Contact service occurs because there is a problem on the phone ui, so that the performance of mobile syistem not optimal, because the contact service could be because of software and hardware, how do I tell? Let's look at the reviews below:
to avoid things we do not want to contact service should we check the software used for software typically damage simlock, ime and pm, for our DCT4 easy fix, but for us to buy hp BB5 RPL file first.
If at the time of checking SW (software) information phone on normal flasher box, then it can be sure of his damage on the HW (hardware)
on HW damage usually occurs in the contact service associated with UI ic, how to fix it, replace the troubled ic!
Good luck,,,,,,

tricks to overcome before mobile short on / off
Good evening the boss, as a continuation of his prior postings about mobile short after on / off. in this post I will discuss about mobile short before the on / off. Short before the on / off switch is very easy to detect, just enough to AVO we are able to detect the mobile phone short or not. Although it is very easy to detect, how to resolve it is still quite complicated. Before we execute ic-ic that tend to short. To avoid things we do not want, we have to search first VBAT capacitors it. There are 2 ways to overcome the short before the on / off:1. measure the capacitor voltage VBATto measure the voltage on the capacitor VBAT we need the PS (power supply) and digital AVO. Well now how to work it?First VBAT voltage of ps we distribute to mobile phones, then we are setting first digital avo to 20V, we continue to snap the ground wire to ground avo phone, after that we measure the voltage across the capacitor, as shown below:
we start from the biggest capacitor first, if the display shows the voltage avo 3.7, already can be sure the capacitor voltage in aliri vbat.kita mark the first capacitor and then we go to his other capacitors, if completed we lift we mark the capacitor was , then we check again if still short, we lift it again the following capacitors. we check again until the phone is completely normal or missing shortn yes.
2. looking VBAT capacitor via mobile schemehow?Here's how to find VBAT capacitor through the scheme:we open the first scheme of mobile pdf format that we want, then we search in the search menu in adobe reader type "VBAT" after we find out the results of the search track vbatx know, the results are as shown below:
The red component is its VBAT!VBAT capacitor how to execute it exactly the same as No. 1. good luck and see you again in the next post

tricks to overcome short phone after on / off
Hi friends of technicians, introduce my name is wahyu,,, would have known for sure,,, already on the blog profile hehehehehe,,, friends technicians must already know the hardest part of the repair hp for SW (software), especially at HW (hardware) ,,,, I personally think the hardest thing for the following HW in repairing mobile phones:
1.a short phone after on / off
2.pure short mobile phone,,,, although not as hard as it no 1,,, but we as engineers are not uncommon in for dizziness,,,
3.(contact service)
4.signal search not found
5.total dead phone
6.handphone break point
to solve problems on the course we as engineers should not be hasty in their stride, instead of profit or loss even what mobile phone in the living conditions, can(total death) if we are wrong to execute, well before we go any further on how to properly execute a mobile phone and the right, let us see review below:
a mobile electronic communication device that includes a series of components that consist of, pcb, capacitor, resistor and diode ic, which etc.yang interconnected with each other,
where the components in dire need of voltage 3.7 (VBAT) which we call battery to maximize the performance of each komponen.vbat itself flows through the capacitor where the line should not be leaking (short) bit, if VBAT is leaking then it can be sure the phone will be(wasteful batteries), as I mentioned above the in 2 types:
1.short after on / off
2.short before on / off
I tell:
1.short after on / off
we turn on the phone with the PS (power supply) if the indications on the screen above the normal rate exceeds the 20A then it can be sure the phone is short after the on / off. as shown below:
But if the indications on the screen PS normal then we have to wait until the phone is standbye. mobile stanbye normal circumstances 0A voltage, if the voltage exceeds or up and down the mobile phone is erratic short after on / off. as shown below:
Why is Short after the on / off???
Short after the on / off occurs because there is a leak VBAT at working voltage, working voltage (vana, vio, v core, vaux.etc)
How to overcome the short after the on / off:
1.If indication amperes voltage exceeds 20A PS, then we
quite touching each component of the mobile phone, if any one of the hot components (except the cpu and flash ic) before we replace the ic is we're trying to pull the first capacitor closest ic, if still then we must change the ic.
2.If his short time standbye the steps we need to do:
1.setting avo us at 25A DC mode
2.When avo plus end of the cable (red) and min (black), black cable that we give VBAT voltage (3.7V) from ps. then the ground wires on the PS we snap to ground mobile, cable plus avo is what we use to inject the working voltage mobile phone, the way we used to pick out voltage capacitor works, only then we shot the voltage to the capacitor, as shown below:
remember! Distinguish between his ground,,, need to keep in mind the cpu and flash ic not be short, good luck and hopefully useful. See you on the post following his
