[G2 and Desire Z Q&A, Help & Troubleshooting] _RaZziel_:
Hi everyone,

sorry for the lengthy post, but I wanted to be precise. Please read the whole of it, if you think you might be able to help. I love this phone but it's useless without WiFi for me. I am also sorry, if I unwittingly violated any forum rules. I tried the best I could.

Currently, I am having a severe issue with the WiFi of my HTC Desire Z. It won't turn on or do anything. First of all: I worked myself through all threads that I could find which were just remotely connected with this issue, also in forums concerning other devices. I still hope I overlooked something... Btw.: My phone is almost 3 years old and a German version. I don't remember what method I used to root it since it was one of the first things I did.

The aforementioned problem appeared right after the following incident: My phone went out of battery while I was listening to an audiobook via Audible. I put the phone in airplane mode some 10 minutes earlier to prevent this, very <irony>successfully<\irony>...

After rebooting, I tried to turn WiFi on, but it just kept telling me "turning wifi on". The switch turned grey and nothing happened. I tried rebooting, turning WiFi on and of several times as well as airplane mode. I flashed the following ROMs, some of which I have been using sometime earlier where WiFi has definitively been working: Andromadus JellyBean by Flinny (version 123, 133 if that matters), all CM stable releases, Andromadus Mimicri 1.50 together with the sugested WiFixIt. With these ROMs I did the same. I could not find any stock ROM that has been able to boot. I did not try to reverse root and s-off (seems pointless to me).

I update the Radio to (afaik most recent version) and I downgraded it a few other versions without any change. I also did a superwipe with the tools given on the following page and reinstalled the ROMs, to no avail: http://xdaforums.com/showthread.php?t=1044992

I also tried different sim-cards (from UK and Germany), both with and without sim-card and sd-card. Also no success.

Bluetooth is working flawlessly. I have just copied a file from my Laptop over to my phone via BT, which is strange, because, as far as I know, both WiFi and BT use the same chips and the same antenna.

I pulled all the logs I found (logcat: main, event, radio; dmesg) and boiled it down to the driver not being able to be loaded. Please correct me, but the WiFi drivers come with the ROM, therefore it CANNOT be due to a faulty driver, since I installed some that worked months ago (tried this before and after flashing different radios).

I reckon that the following parts are the important ones, but I attached the complete logs (cover the boot process and me trying to turn WiFi on) to be on the safe side. As far as I understand, it just says that it tries to load the driver bot fails to attach some kind of module.

Dmesg:

Logcat main:

Methinks it is a hardware issue and I am very close to taking the thing apart, which will possibly break something else... Second last comment: As I try to turn WiFi on via the status bar, it reboots after like one minute. Last comment: Is there any way to check whether it really is a hardware fault?

I apprecieate any comment intended to be helpful. Even when it is you telling me that it IS a hardware issue. If you need any further information, I am more than happy to provide it. I would also be happy to make the life of my phone-saviour more enjoyable with one or two pints of something, if we can arrange a meeting.
