New board new radio chip- better reception?? - MTCB Android Head Units General

Hi
A while back I thought I toasted my motherboard using the 7floor mod. I managed to get the board up and running. I ordered a replacement from HK and it has now arrived.
Now looking at the new motherboard there is a different radio chip TDA7388 which is mounted in the rear (no chip on the original board). Do you know if this chip would have improved reception as the older boards radio reception is poor with a chip TEF6686, lock does not work too
Here are the photos.

This is the amplifier IC, not the radio!

I have great reception with the TEF6686

The best is the Placebo brand chip.

Are one of these boards the GSM board? i know one is GPS and one is UMTS (does that handle the GSM too?) Or what else might have caused me to loose signal capability?
Why did you replace the digitizer? What was the problem in your case?
.....I think UMTS handles GSM also.
Thank you! Yes i fixed it, and the UTMS does handle GSM too.

[Q] Seidio Case Question

Just bought one for the IncS & now looking at some other cases I notice they have extra holes for the ones on the phone while the Seidio cases doesn't. Does anyone know if these holes serve some purpose that they should not be covered?

I never even notice those wholes. I have a case that covers them and I never really had a problem. Although I find that if I have a week wifi signal and I take of the case it improuves a little bit.... but that might be in my head heheheh
remove the back cover, you can just see these holes correspond to the gps, radio module,
I guess these holes should be improved for the signal role of some..

[WIP] Wireless Charging on IncS

I am planning to install wireless charging in IncS.
I would need some advice from experts in order to move forward.
On going through various forums on internet, i came across a small difference between the HTC Droid Incredible 2(Which supports wireless charging) and IncS.

There are 4 small contact points on both the motherboards(Marked and circled in the pic). But on INcredible 2 there is a small plate soldered on those. Whereas, on INcS there is no such thing. I mean there is no way a Qi compatible charger receiver can touch the motherboard.
My question now is that should I get this thing soldered on IncS motherboard or do I need to do something else also?

I bought a new back cover on ebay... It comes with all the antennas, but, in my case, it didn't help
My gps didn't work and after exhausting all software attempts I came across the antenna issue. On mine I put 3 very thin pieces of vinyl electrical tape under the antenna connector pads. You might want to start out with 1 or 2 pieces to start. When putting the cover back on that section required the most force to snap back into place. But it works like it should I'm glad to say.

Xperia z1 digitizer

Hi. I have xperia z1 with broken digitizer, but it was working half way. I bought new digitizer with lcd and frame, replaced it and touch is not working. I sent this lcd/digitizer to service to be sure it's ok and they said me that it is ok. So what i think i have done is i ripped off from the mainboard a small capacitor or resistor when i was uncarefully unpluging screen. So it doesnt work anymore. And i have a great request if someone have their phone apart to give me closeup photo of area that i pointed in picture so i can solder something here. Big thanks in advance.
