WiFi "Error" after installing Android 2.2

If you get a reply, please let us know. 

Judging by all the solutions we've found so far (and which didn't work in your case), I guess they'll ask you to send the phone back for repairs. 
But then again it wouldn't be the first time that HTC had one more trick up their sleeve that we couldn't possibly think of. 

I finally solved Wi-Fi error problem by downgrading to previous firmware version ("2.09.405.8") and then updating again to "2.10.405.2". Everything was done running .exe update files on PC connected to Desire (not via Wi-Fi It's improtant!!!)

OK
1. Download this update: http://shipped-roms.com/shipped/Bravo/RUU_Bravo_Froyo_HTC_WWE_2.09.405.8_Radio_32.43.00.32U_5.09.00.20_release_140022_signed.exe   (login and password: shipped).
2. Connect Desire to PC via usb cable.
3. Run downloaded .exe file (HTC Sync is required) and wait for downgrade to finish. After downgrade Wi-Fi should be OK again.
4. Upgrade to latest 2.2 version: http://shipped-roms.com/shipped/Bravo/RUU_Bravo_Froyo_HTC_WWE_2.10.405.2_R_Radio_32.44.00.32U_5.09.05.30_2_release_142828_signed.exe   as was described before.
After this upgrade Wi-fi should work.
Avoid upgrading via Wi-Fi in the future, use .exe files instead.

By the way, I thought I'd try running the two updates a second time just in case, and now I get "Error 140 Bootloader Version Error" when I try to run the first update. Is that significant?

Hi, just had the exact same problem - upgraded to latest OTA 2.2 update (v. 2.10.405.2). Everything worked ok, except no more wifi. Did a little searching around and found this forum Did some more searching and problem now fixed - phone now running 2.10.405.2, upgraded OTA, wifi working.

So as far as I can tell, this mainly (only?) effects people who've unbranded their phone. Main cause of the problem seems to be upgrading without a working Goldcard installed in the device (I thought the card in my phone was a working Goldcard, turns out it wasn't).

First, ensure the current SD card is a Goldcard (probably worth doing this afresh). Download the previous version of the HTC Desire Rom, downgrade your phone. You can then upgrade over the air and it should all work fine (did for me anyway!).

Easiest way to make a new Goldcard - download and run 'GoldCard Tool'

HTC Desire Rom link from previous post didn't work for me, so I used this instead:
RUU_Bravo_Froyo_HTC_WWE_2.09.405.8_Radio_32.43.00.32U_5.09.00.20_release_140022_signed.exe

Hi there,

I had a an unbranded and unlocked HTC desire with an orange sim. After a small OTA update, the wifi started to show an error message. I tried all the solutions here but none worked. The solution that helped me was as follows:


After applying the latest OTA update onto the recently debranded froyo update (Software number 2.10.405.2), I found that wi-fi was bricked. The latest OTA update included a radio upgrade. My phone had my usual sd card which was NOT a goldcard. I found that the radio version did not update but that the rest of the software did.

The solution for this particular issue was posted in the comments of the original article http://www.androidcentral.com/htc-desire-receives-performance-update

i.e. Solution for bricked wifi (after applying 2.10.405.2 update to a debranded phone) if you did not use your goldcard:

i) Put the goldcard back in the phone, download the update from the htc website: http://fotadl.htc.com/OTA_Bravo_HTC_EU_2.10.405.2-2.09.405.8_releaseol2djq7rqarka2ka.zip

ii) rename that to update.zip and place on the root of your sd card (the goldcard!)

iii) Apply the update.zip just as you would have for the froyo update

and your wi-fi works again!

Here are the final details for comparison:

If you don’t use your goldcard, HBOOT and RADIO does not get updated. Hope that helps!

Hi HTC Freakster

Everything you've out here makes sense. The only reason I have paused before doing the update is the EU in the zip file. Is this a European update?

My phone is Ex Singapore. Can you confirm is this update appears correct or point me to a link for the OTA for the Singapore/South East Asia.

Thanks.

@14Data

Yes it's a European update and can't confirm if it will work for Asia. My model is HTC desire A8181.
The links i have provided have a wealth of info-may answer your specific query. Otherwise you could email HTC in Asia asking about the small update if it is provided by them for direct download.

Gud luck.
