I got the same board....Works normal

Can you tell if it's the same board that you sent out? Wonder why they've also replaced that chip with a daughter board and oscillator? Can you post the part numbers of the new components on the daughter board?

This is not the same board as I sent out. I don't know if it takes the latest drivers, I was told not to update, my previous board got bricked with the latest drivers. The chip has all the numbers grinded off, I can only see the numbers on the oscillator if I open the box again. Like the previous board this has no identification on it.

Can you identify the board maker? Is it Lonrisun, Dragonworth or other?

Its a Dragonboard look at my pictures...

Im a bit confused now ... my board did get bricked with the easter time bomb, I did have an original image on it with the latest drivers, it did accept all images I tried. I thought that was not possible with the dragonworth solo2? But it looks exactly the same, with the little white round sticker and the "tearing up to void" sticker.

Were you able to update this board to V3?

 

[dirkjan73]

The strange thing is that Dragonboards lately also got bricked...I dont know know why and how....The Chinese say you have to do the V3 update,ive putted somewhere on the,then you should be safe...

You are so right !

The original vu products by the way are poorly designed as well they require proprietry broadcom BBS tools/JTAG to restore corrupt bootloader. So if you own a genuine box and your out of warranty you have to use unofficially obtained BBS tools software to fix a corrupt bootloader...

No its a Dragon

Looks like the Lonrisun (the motherboard and design of circuit), but I understand as you wrote that it's from Dragon manufacturer.

With this different looking chip, that has only a few connected legs, and all the missing components around it my box doesn't seem to have any CAMS, and cardreaders are not working. I think the CI is working though. I'm only using softacams, so it wont bother me, but the Chinese seem to be cutting corners where they can.

Hi all,

I have some quick questions regarding the change of the chip inside the solo2. I'm inspiring from the below youtube video to replace the chip:

how to replace a flash on VU SOLO 2 - YouTube

It's important to detail i have some background in soldering chips and i successfully changed one chip on a solo2 already. Maybe i was lucky, i don't know.

The question is: it is absolutely not working for me when i'm trying to reproduce what the guy is doing on the video (see as from 1min). For my part, the iron still stick all pins together and i can't get it clean as he does. I have the feelin that i'm using the same iron tip as him (45° 1mm).

I'm using the soldering station:



So i don't know what is the issue:
- Am i not using the same iron tip as him?
- Am i using the soldering station at wrong temperature? (too high or too low ?)
- Am i using wrong iron?

I'm using this iron tip: LF-1BC


Regarding temperature, i'm using around 300°. Don't want to go too high to avoid pins burning/jumping from the PCB.


Thanks for your advices!

Thanks for the info! If that the same of the below article?

Flux PEN Future 315 Warton Metals | eBay

Because i got one of these that i bought together with the right iron tip.

Thanks for the advice.

Slightly off topic from chip changing.

Been reading a lot the last couple of days and if vu have ever released the source to the drivers causing the problem I can't find it in their repo.

So, it's not the bootloader or the kernel at fault.

Can we not build a new image from pli using generic drivers if available.

Or seeing as all these images are based on clones of dm software why is there no images using Opentv free86 these boxes are not limited to the extents of the old hardware their software is based on.

The chips could possibly have been blanks?

 

[techtechnique]

I don't know if this has already been covered, but I've just found this:

http://www.alibaba.com/product-detail/linux-sunray-vu-solo-2-v3_1927802068.html

I'm assuming that the "service port" is a connection to an in-built Cypress board for JTAG, and also note that the flash chip is now on a pluggable daughter board.

So much for an imminent RS232 solution.

 

[casuk]

I just woke up this morning to find the spinner on screen rebooted and i now have all the signs of a bricked solo2 anyone got a chip for sale and who can fit it

 

[techtechnique]

Has anyone successfully restored a sabotaged flash chip (coz let's not beat around the bush, Vu+ have actively sabotaged non original equipment) using the JTAG / Cypress method, or is chip change the only way forward to revive our clones?
