rooted mine my bros and bros girlfriends desires...
all went fine, no problems.
then my bros girlfriends started doing this thing and would'nt connect to wifi...it says turning on then error.
i thought ok, its an old rom version updated to the latest along with the latest radio 5.20 (or whatever it is ) and still the same....
ok...must be the rom...tried opendesire, which is working perfect on my phone and its still not working....
so to shortlist the problem is when i try connect to wifi it says turning on...then error...and wont even turn on...
definately not the rom.
definitely not the radio.
anyone got any ideas?
i tried to flash back to stock RUU but it would not let me "update" it with an HTC ruu a europe RUU and even a TMO UK ruu....
just kept saying cant update....
so anyone got any suggestions?
thanks!!
The same problem with me. I flash several ROMs, but no change. I think it's hardware fault.
Full wipe before flashing new roms? Have you tried a FroYo sense rom?

Now i use office 2.2 ROM, the same problem.
ye wiped and everything.
i cant even flash a RUU package which is gay!!
ill try a few other things and see if i can get it to work....and then maybe just send it back for repair or something.
I seem to have the same issue did anyone have any luck?
Just to give more background to me issue:
I've come up against a weird bug\issue\failure.
I've been running Leedriod ROM for a while with very very few issues. I upgraded to 2.0c over the weekend & everything was working fine.
This morning however neither my wifi or bluetooth is work.
Wifi tries to start but I simply get "Error" in Setting-->Wirless & Network-->Wi-Fi
My bluetooth has also stop working.
I'm not sure if this is related to the Leedroid ROM or potentially a hardware failure...
I have gone back to 1.9 (last know good backup) & I've done a complete fresh wipe & install of 2.0c. None of which I have had any luck with. I've also trawled the web and forums but nothing similar is popping up....
Any help or advice much appreciated...

Didn't my advice in another thread work?
It sounds like you guys have what's called a usb-bricked phone.

Sorry, mate...somewhere in my brain I thought I have replied to you. I tried the USB Brick Fix you suggested but no luck....
I'm beginning to think it's a hardware fail....
Normally means you didn't update with the gold card in the phone - you need this for ALL updates on previously branded phones...
What exactly is a USB brick? Does it brick the phone or just stop the USB from being able to update the phone?

Hey, I have much the same issue, I've tried a whole lot of ROMs and none of them seem to make the wifi work.
As soon as I revert back to the original installation it's working as expected, but whenever the phone is flashed (with the updated radio too), wifi stops.
As far as I can tell, Bluetooth, GPS and 3G are fine, but wifi tries to connect states that it's "Acquiring IP Address" and then disconnects and starts the cycle again.
Any help would be greatly appreciated.
Thanks.
Do you use the gold card when updating?

Hey, no worries!
Your symptoms definitely suggest your phone is "usb-bricked". What method did you try?
This is the best (and easiest): http://android.modaco.com/content/h...com/309939/usb-brick-rickrolled-b0rked-fixed/
I followed it myself with success some time ago.
If your phone is no longer rooted, you will need to root it. Else start with step 2.

I've never used my gold card when updating my branded Vodafone Desire.
I only used the gold card for initially rooting my Desire!

Sometimes when a update/flash goes wrong the Desire going in to a low level debugging mode, which we refer to as a "usb-bricked Desire".
You will observe the following symptoms:
* FM Radio Malfunction.
* Bluetooth Malfunction.
* Charging doesn't start immediately.
* Radio Malfunction.
* SD Card Malfunction.
* Unable to connect your phone using USB when booted into Android.
* Unable to connect your phone using USB in Custom/Pushed Recovery.
...other than this, the phone will work as expected.
So the WiFi problem is something different. I was directing my reply directly at IEArmand because we were chatting on a different thread.

Thanks for the info, was just curious as my Desire, although now fully updated, didn't seem to like the latest RRU update file and couldn't be connected via USB. It's weird as disk mode and sync still work completely fine and it updated fine via OTA.

Ok this is weird.....
Woke up this morning and found my Wifi and Bluetooth functions have returned!! I did not try anything last night so I'm at a loss to know what has fixed it.Functions did not return right after USB Brick fix but who knows...
Not much help to folk with this issue I'm afraid..

Hey, I rooted my phone using the Unrevoked method, I didn't think I needed a Gold Card to complete this.
Maybe I read this incorrectly. Can I just repeat the process with the GC?
And...does the GC help with Rooting or Flashing?
Thanks.
That's rooting, you don't need a gold card for that. If you want to flash a generic ROM onto your branded Desire you'll need a gold card. If you want to flash a custom ROM, you just need to use a custom recovery (which you'll have thanks to unrEVOked)
As for JustinTrouble not needing one, I'm guessing it's just Orange users having issues then as most people need the gold card to stop the WiFi issue rearing its head
i just recently tried to root my htc evo running the new 3.70 ota update, and i get a message saying "error: failed to get root.Is your firmware to new?" i initially thoguht it was the fact i had easy tether on my laptop, but i uninstalld it and retried again, and nothing. i hope nothing got messed up, my phones working normal, but idk what happened can anyone help? thanks and sorry in advance
ok i fixed it it turns out some apps on ur phone interfere with the rooting of the device im now rooted using wifi tethering to post this
What apps effect the rooting process?
Unrelated question: I just rooted using Unrevoked on my phone and for some reason when I am at home it says my current location is Chennai, India. I am actually in Dallas, TX though... Any ideas to why it isn't updating correctly?
Hardware Rev: 003
HBoot: 2.1
i actually just uninstalled a couple aps like tikl and tango video calls, easytether and couple more apps just made some free space there and retried and it worked perfect
and for your location double check all your settings are correct like use current location, i just rooted and my location is fine.

I myself have expierenced this same issue , was putting me in England lol how the hell it got that is beyond me . There is also a thread over on www.androidforums.com as well that this issue is being discussed on . I have the new Hboot and most recent update of the stock software then rooted the phone . I flashed Myn's rom and the issue cleared itself . Im going to assume there is something that gets triggered off by the new software . People reporting this issue are either rooted or not rooted . So that by itself should remove unrevoked from the equation . Some in the thread have said to force whatever app you are using for location to refresh itself then unclick sync then restart sync and refresh one more time . Again this fix has worked for some and some it has not .
Hey guys,
im running a Desire with the newest Leedroid Rom. Everythings working perfect,
except the wifi network connection.
My Problem:
After i updated from branded 2.1 to 2.2 with OVA Update, i cant connect to any
encrypted wifi. I dont get an error or something, it just tries to get a ip adress
and then it says Connecting... and then it starts again from trying to get an
ip-adress and so on and so on...
The only thing thats working is to connect to an open wifi hotspot.
Things i tryed:
- Other Router, other settings, other decryption, other keys,and so on
It has to be a problem in updating process, cause with 2.1 it works and after i
update to 2.2 i cant connect to any wifi anymore.
I really need help cause i think this cant be a hardware problem, cause everything else is working.
Sry for my english, tried my best
nge89
Do a full wipe and flash leedroid again.
I have done full wipes like 100 times, also im always testing new roms,
so i was on modaco,leedroid,cyanogen and installed them many times.
So that cant be the problem
nge89
First how do you do a full wipe?
Second what is a OVA update? is it the same as OTA? And what does the update have to do with your wifi not working on leedorid? Did you OTA update form a rooted 2.1 rom?
Has wifi ever worked on 2.2? What radio are you using?
I do a full wipe with all 4 wipe options, dont know the exactly names.
Yeah sry,with OVA i mean the OTA.
No, i did a OTA Update from a branded unrooted 2.1 Desire to the branded 2.2 Froyo version. And wifi NEVER worked on any 2.2 version.
I just rooted my phone when i was on branded 2.2 version, cause i wanted to
try some of the nice roms.
In this time i never used wifi, only mobile network connection, cause i was long
time not at home and couldnt use any wifi, now im back here and trying to solve
my wifi problem.
Just checking my Radio version and i have 32.36.00.28U_4.06.00.02_2, but i dont
know why, thought i had installed a newer
Should i try the 32.49.00.32U_5.11.05.27?

Yes looks like 2.1 radio, try the newer but do not pull the battery during the update it will reboot twice and don't touch anything during the process. I take no responsibility for what happens and I suggest you do some searching on the radio flashing process. Also don't forget to check the md5 of the download.
Might sound a bit scary but if you follow the procedures and don't do anything stupid it should go well.
i encountered the same problem only i'm on 2.1 after downgrading from 2.2 and rom jumping. did a wipe and even tried to nand restore my original stock rom. is this a radio error?
the phone was working fine. this issue happened to me while i was trying to fix a battery drain problem, i did a dalvik + cache wipe and the battery was fixed but the wifi started doing this. my phone could still be on the 2.2 radio

Would be nice if you would post the radio version
was about to edit my post with the info, you beat me to it
Radio: 5.11.05.27
HBoot: 0.93.0001
Im now also on 32.49.00.32U_5.11.05.27. Still the same Problem.
That u can imagine how it looks like:
1. Wlan -> power on
2. Select my Wlan Acess Point
3. Type in my Wlan Key
4. Its says Wlan -> " The Connection is now being established"
5. Wlan -> "Authentication with "Wlan Accespoint name" "
6. Wlan -> " Not Connected"
7. Wlan -> "Scan..."
After this steps it repeats from step 4-7 again and again and nothing is happening.
nge89
Also tried with another keyboard, in another thread someone said it worked for him
with another keyboard. But not for me, still the same problem.
nge89
ok i fixed the problem and now Wifi works perfectly!
I downloaded the same version radio and flashed it again from AmonRA recovery and now the Wifi and mobile network work just fine.
I got the radio from this thread and it has the instructions on how to flash the radio.
http://forum.xda-developers.com/showthread.php?t=687464
I just flashed the radio with clockworkmod and with install zip from sdcard. Is that wrong?
You had the same problem like me?
Nge89
Sent from my HTC Desire using XDA App
no its not wrong, thats what i did only with AmonRA. yeah from your description i had the same problem. The wifi would detect my wireless network but would refuse to connect and kept giving me "unsuccessful" errors.
The problem is, that i dont get any error.
Sent from my HTC Desire using XDA App
Some one any idea?
flashing the radio again didn't fix it?
Did you try to disable any protection (wep, wpa, wpa2) on your router and then connect? Also try to disable dhcp on your router and assign static IP adress to your HTC device. I had problems connecting to wifi but after I assign static IP everything is ok.
Yeah, i can connect with disabled security. With static ip and crypted wifi it
doesnt work, i cant connect.
nge89
Then your problem most probably lies in "shaking" between HTC and router. Did you try with basic 64 bit or 128 bit wep? In many cases shaking troubles occur when one device doesn't support encryption of another. For example I had troubles connecting my windows 7 because of ****ty drivers off my wireless card. I could only use wep. Also can you check that portable wi-fi hotspot in wi-fi hotspots is disabled? And try to add your wireless manually so when you enable wi fi it should connect you automaticly without having you to enter your password.
Hi all, I've done a search but can not find a similar problem.
I have Eclair 2.1 running on my Desire. It's rooted
The problem is I can not connect to my router (or any other router for that matter).
The phone does however recognise available wireless networks. Allows me to select my home network and enter the WEP but just doesn't connect. It also has a MAC address allocated on the phone.
One thing I am unsure of is when I try to enter the WEP key, just above the input box there is the drop-down option to select Key Index of which the options are 1, 2, 3 or 4. What does this mean?
I've also got the option to update the OS to Froyo 2.2. It's an OTA update and unfortunately my only option is to do t via 3G as I can't do WIFI (as stated above). Almost 90mb!!!
Will there be any issues with installing this update... considering this phone has been unlocked, Rooted and has ClockworkRecoveryMod?
Don't want to waste 90MB to find it doesn't work.
Just a suggestion. try disabling your router security and see if it connects then. If it does try using Mac address filtering instead so the desire will think it's just going onto an unsecure network.
Why would you want to take the official OTA upgrade to froyo at this time when there are a bajillion custom froyo, desire hd and gingerbread roms out there?
If you like htc sense and froyo, then i suggest you try leedroid. Its pimped up stock froyo. And you can download it onto your computer first. Plus its guaranteed to work.
If I'm not wrong, doing the OTA update will overwrite your hboot and recovery as well, thus unrooting your phone. And the newest hboots may be shackled down with more security that existing methods cannot unlock- your phone may become unrootable.

Unfortunately... very unfortunately indeed... I went through with the OTA update via ClockworkRecovery. I used the 'Apply SD Card/Update.zip' option before I read your reply.
I've bricked my phone!! It won't go bast the initial HTC screen.... just keeps rebooting. Yes... I'm kicking myself for it now.
I've lost recovery mode now. I can get into the initial bootloader screen but when you select the option for 'Recovery', I ust get a pic of a phone with a hazard sign [!]. Very bad. It doesn't repspond to anything and the only way to turn it off is to pull the battery.
Any suuggestions on how to fix or have I got a dud phone now?
managed to sort it out eventually. Phew!!
Still got the wifi issue though
I've changed the Router (o2 wirless box) settings from WEP to WPA/PSK.. also selected different channels and even tried it without any security on at all (open network)... but my phone still won't connect. It scans perfectly fine and finds the network. Just won't connect.
I thought the Froyo update might hep fix it but to no avail.
i'm never going to get to the bottom of this am I?
Running Oxygen 2.3.2 on a rooted and S-OFF HTC Desire (stock HBOOT), which I flashed tonight.
The WIFI appears to connect to my home network but the phone does not actually receive any internet access.
Prior to rooting I was using the WIFI without issues, and nothing has changed in the network since I rooted - my laptop is currently successsfully connected to the internet.
Security is WPA/WPA2, which I changed from WEP ages ago when a buggy tablet wouldn't connect and I was checking it wasn't the encryption that was causing the problem. the phone was connecting to the WPA/WPA2 succesfully. No proxy.
I've searched and haven't found anyone with this exact issue, so I'm not sure how to go about troublshooting.
- I didn't think flashing the Oxygen HBOOT listed on the alphadev site would solve this problem, so I haven't done that yet.
What's your radio version?

5.09.05.30_2 (stock radio).
Although I haven't checked since I flashed either cyanogen or Oxygen (WIFI wasn't working on cyanogen and I didn't like the ROM a whole lot anyways), but I don't think custom ROMs touch the radio - unless I'm mistaken?
You should definitively upgrade your radio version to the latest one - 5.17.05.23. You can find download link here: http://forum.xda-developers.com/showthread.php?t=687464 The latest radio is highly recommended when using custom ROM, because they are usually tested with latest radio.

Okay, cheers, will do.
EDIT: Nevermind, after scrolling from 2010 to 2012 posts and across two forums, I found the answer (simplest response is on here for anyone interested -- essentially, the method listed is apparently a very old one, pre-recovery days. Just use recovery to flash the radio like you would with a ROM. No wipe needed, apparently.)
I'm assuming you've done this already?
If so, could you explain step 6 - where do I get the .bat script / modaco r5 root pack... Do I even need it since my phone is rooted and has recovery etc?
(I've read several people saying you "just flash it like you would flash a ROM", so I'm guessing that means loading the radio's .zip file onto my SD card and flashing from recovery like I would with a ROM?)
1. Turn your desire off
2. Hold the back button and turn your desire on
3. When you are at the white screen, make sure BOOTLOADER is selected and press the power button
4. Wait a few seconds then press volume down to select RECOVERY and press the power button again
5. When you are at the screen with the red triangle and the phone, plug in the usb cable
6. Run the recovery-windows.bat script from modaco r5 root pack
7. When the recovery menu appears select 'Flash zip from sdcard'
8. Select the radio zip file and press the trackerball to confirm
9. Press the trackerball over 'Reboot system now'
10. When the radio image has finished being written unplug the usb cable
11. The phone will reboot a couple of times and then return to a normal state with your new radio

The steps you found are probably outdated. It's really simple. Download latest radio and put it to the root of your SD card. Then you have to reboot to recovery (directly from running ROM or with volume down button pressed when powering up the device). Once you're in recovery, select update from zip (I don't know if you're using Clockworkmod or 4Ext) and choose zip file you downloaded before. Device should reboot and reflash the radio. That's all...
Does upgrading the radio influence the WIFI though?
I've been reading the radio-related post that lists the newest radios and there's a lot of talk about GPS and signal strength improving / worsening with radio changes, but haven't yet found anything relating to WIFI.

Ah crap
Just flashed the latest radio (5.17 etc) as I would with a ROM - yes I did a nand backup using Amon Ra.
Anyways, flashed it - told me it was doing its thing, asked me to restart system to allow it to finish etc, so I did.
It flashed to the HTC boot screen, then returned to Amon Ra recovery
Its now been about 5-10minutes and there's a msg saying:
Build: RA-desire-v2.0.1
Formatting CACHE:...
And that's it. Hasn't moved a bit since that screen and msg came back.
What can I do now? I can navigate the Amon Ra recovery menu, but I'm scared to reboot the system in case I brick my phone.... help please!

So I accidentally solved the problem when I accidentally hit hte trackball and confirmed the "reboot system now" option from the main menu.
Radio is upgraded successfully by the looks of it.
Unfortunately though, WIFI still doesn't work
You've gone through all the trouble of changing your radio. Did you ever bother to try other roms first?
You say that nothing has changed with your wifi connection but you are using a secured connection. Did you even tried a connection with your wifi unsecured and try to establish a connection with the phone?

If you're going to just get narky, then I'm not sure why you're posting, tbh.
Yes, I had used cyanogen 7 prior to oxygen and had the same problem.
And I only flashed oxygen on Monday night, so I don't have the luxury of running around finding unsecured wifi during my work days.
Having said that, a neighbour leaves unsecure wifi on late at night, and I can pick it up and managed to briefly connect to the net before the signal strength died., so yes I'm assuming I can connect to at least one unsecured network.
Which I guess means something's been changed in the scripts running in custom roms vs stock, which isn't helpful.
Well, could you confirm you have the latest radio now? I mean was the upgrade successful? Did you try to do nandroid backup, wipe device and test from scratch with fresh install?

I'm just suggesting things that ya'll may have overlooked. I've used CM and Oxygen and never had any issues with wifi may it be what type of security being implemented.
Well after playing around with my router's settings for ages, I finally made it work by changing the mode from "b/g/n mixed" to "b/g mixed". I was able to keep my WPA2 security on.
- Yep, radio was succesfully upgraded, even though it didn't appear to be.
I guess these custom ROMs do something to the WIFI component of the Desire because I was able to connect to the network with the b/g/n mixed mode in use before I flashed the custom ROMs.
This is annoying because it means I'll likely not be able to use any public WIFI hotspots that are set as b/g/n mixed...
Just to illustrate how tricky this can be. I had the same symptoms on my HTC Desire: Wifi connected OK to a b/g/n router but would not transfer any data through browsers, email, PlayStore, anything really.
Initially running Miui 2.4.9 and Wifi was OK.
Upgraded to Miui 2.4.13 but the ugrade did not complete successfully. The phone worked except that Wifi connected but didn't work.
Restored the phone with an earlier backup of MildWild CM-8.0 ROM which used to have working Wifi. Wifi still no good.
Flashed latest Radio 5.17.05.23. Wifi still no good.
Flashed earlier Radio 5.09.05.30. Wifi still no good.
Flashed full GB Miui 2.4.13 ROM. Wifi still no good.
Re-flashed latest Radio 5.17.05.23. Wifi works!!!! WTF?
