Can anyone can answer my questions in mind?

1. Do apploader can be used 2 handheld at the same time?
2. What wrong with my phone if it is only white display appear, I just check all basic checkpoints and even replace good LCD from working one. Also have tried to re install OS but still no luck?
3. Is there any version of 8530 LCD?

What country are you in?
What phone service carrier are you with?

Note that you cannot have an 8530 on "nextel"?

Yeah i know...im a technician and im not familiar with this phone. Im still analyzing its components and how to fix if it is a software problem. Its a verizon carrier. Lot of board i have here is White screen problem and wondering how can i fix it i even dont have a schematic diagram.

I'm still having a hard time understanding what you are saying since English does not seem to be your native language.

In your original post, what does your first question mean?

And where did the device come from? What kind of damage has it been exposed to?

I mean if probably possible to flash 2 handheld at the same time using loader.

Yes. Start one then plug in the other and start that one.
