T-Mobile Shadow - No Wifi Problem

---

We refurbish and sell HTC phones. Currently we have received about 250 T-Mobile Shadow phones.

Upon initial testing we are finding that some of the phones the wifi does not function. After some reading I see that this is a common problem. Some people have resolved with hard reset, reloading rom, and one by changing some hardware.

We have tried all these steps and still have not gotten any defective ones to work.

Has anyone had this issue and able to resolve it?

I wrote on the wiki some information about it but so far there is no solution.
So far I could "isolate" the problem to the circuit board on the screen part that control the wheel/d-pad and probably the wifi part.
If you use that part from a working wifi phone with the mainboard from a non working wifi phone you can get the wifi to work.
You guys probably can get more info from HTC on that as for me, they simple answer "thanks for contacting us, you need to check with your mobile company or send to repair" but no info :P

FROM THE WIKI

WiFi Problem:

• <LI class="tightenable top bottom">Some versions of this phone are cursed with the "driver is not loaded" error while trying to use the WiFi. <LI class="tightenable top bottom">Some people reported that doing a hard-reset solved their problem.
• The cause and solution for this is still unknown.

Software "view" of this problem: On a broken WiFi phone the radio stack wasn't corrupted, all the files and registry seamed to be correct.
Hardware "view" of this problem: Swapping parts between a phone with working WiFi and one with broken WiFi, the problem was isolated to the circuit behind the d-pad wheel where the screen is attached to.

On the working WiFi phone:

• <LI class="tightenable top bottom">The writting on the antenna reads: the manufactured date and the word PHOEBUS
• The stamp on the microSD slot reads GUKE

On the broken WiFi phone:

• <LI class="tightenable top bottom">The writting on the antenna reads: a version code and the word PHOEBUS
• The stamp on the microSD slot reads GTIE

Print that out take it to t-mobile and tell them you have a manufacture defective phone and you want a new one.

I tried that and it worked, but my screen quality lost and it was kinna yellowish and at different angle the screen looks different. why?
