Try changing the modem to the one you originally had (assuming your phone's mobile network did work before).

I used odin to upgrade to gingerbread 2.3.3 , i then downloaded rom manager [which i learned was a stupid idea] , i cleared the cache i think it was with the rom manager and now i have no web connection , no 4g symbol at the top any more. Did a factory reset and everything and nothing fixed it.

I had the same thing happen with my wife's phone, posted a thread in Q&A
http://forum.xda-developers.com/showthread.php?t=1338170
Turned out that flashing the CWM KJ6 modem was causing the phone to not see the SIM card. Not sure if you are having the same issue. Reflashing Valhalla 1.3.2 resulted in everything reappearing and the phones been fine since. Check your mobile networks tab under Wireless and Settings. If it tells you to insert a SIM card to log on to available networks (you already have your SIM card inserted) then reflash the GB ROM and don't mess with the modem - that should fix it.
EDIT: Once I lost the SIM it didn't matter which modem I flashed it wouldn't come back. Reflashing the whole ROM did the job though.

ALright thank you for the info i am going to try this right now

now while trying to install the GB again in ODIN im gettin a fail.
now i have the firmware upgrade fail screen.
I read this is still fine for installing GB on ODIN , so i tried again. Still getting fail. i read that you can remove your sd and sim card and it should work. still getting fail!
can anyone help !
im folling the instructions to a T.
Hit PDA add the zImage-root.tar file
getting fail

Im using a mac and transfering the files to a old window laptop without internet connection =p

[Q] CM7 issues

I installed CM7 on my infuse yesterday and having an issue. I have read alot of forums but haven't found an answer. I am having connection issues while using the phone. I have flashed different modems still doesn't change anything. When I am using the market I get connection timed out. It switches between H, 3g, and E all the time. Is there anything else I can do to fix this?
Thanks in advance.
Read thru the cm7 thread in dev section is a good place to start ready to find your answer. Me personally have no data issues while on cm7

Look for the APN fix it is in many places.
My data dies when I first access the market. After I leave the market and it will come back and I have no trouble after that.
As for it switching between 4,H,3,E CM7 is giving you real connection info when other ROMS do not.

1) Do you require bluetooth? If yes, don't use CM7. 2) Can you read instructions? If so, there's an easy fix for the APN thing and you'll be all set. CM7 is fantastic, I've used it for a long time.
In the instructions he asks to boot into recovery and flash the rom. now when i reboot into 3e recovery theres no option to install from zip... all there is are these options: reinstall packages, delete user data, delete cache data, format internal sd card...
---------- Post added at 06:16 AM ---------- Previous post was at 06:12 AM ----------
ok... figured it out... had to select reinstall packages
I like cm7 on every phone I have had, my phone runs 100% better, remember step where u flash again and to download Google apps zip to get market to get all ur apps and I'd recommend getting titanium back pro. I like backing up all my apps. Faster to load ur stuff back on phone.
Sent from my SGH-I997 using xda premium
thanks for the tip... i was a bit confused where the market place had gone
apps are downloading now... i backed up me apps and data with titanium... now when i restore, my apps and data will get overwritten i assume....
guys, sorry for the wrong section..
When flashing my ACE,i I need to root it first??

Yes. You can root using SuperOneClick.
Yes it some apps don't always restore well via backup though. Like adobe I usually restore flash without data. Free version of titanium back will piss you off it stops on every app it restores.

start over as in reinstall gapps or reflash rom? and the steps for reflashing are the same as before or something different has to be done? and this time i should avoid restoring titanium backup??
I would wipe, reflash, I only restore user apps via titanium backup. Might download Google apps again. You only have to flash once if ur on cm7, just wipe flash cm7 and then flash Google apps. Then reboot.

ok...by wipe you mean format /system from recovery and reflash? also i have this weird thing where wifi icon no longer shows up if the phone is screenlocked for some time. when you unlock the wifi comes on. is the a CM thing or some setting i need to tweak for always ON wifi... thanks for all the help!
Also should I go to th 12/13dec build or the 20 nov build thats the latest on the links???
Wipe in where recovery and flash is. I would use newest build 12/13. I just haven't had time to update yet. Wifi, not sure where setting is since I don't use wifi with screen off but in past many phones would shut off wifi when screen goes off.

Definately go with the latest 12/13 and when you are in wifi setting hit menu button and advanced settings choose wifi never sleeps

[Q] Need help : Com.Android.Phone failed

I have a Verizon S III (Stock, Rooted). I was travelling internationally with it and was using it on GSM (using HiAPN app). It was working fine and then Com.Android.Phone failed msg popped up. I lost outgoing calls due to that. I tried various things and ended up doing factory reset. Now when the phone powers up it tries to activate and fails as I still get the com,android,,phone failed error. I also flash JB rom but I still get the same msg.
Any suggestions in this situation?

Did you do a full wipe and flash the latest JB rom or just re-flash the JB rom and leave your settings/apps intact?
Did you switch your sim when you went global? Did you switch some phone settings? Did you use a program to alter your APN (?) settings? What did you do to go global?
If yes to any of the above -- that's probably why. You need to be more informative in your post. Your post as is basically says nothing.

Yes, I used a local SIM card. I used a program called HiAPN to switch APN settings and changed the network from CDMA/LTE to GSM/WCDMA preferred. ,

[Q] WiFi not working

HTC One XL on Telstra
I just updated my firmware to 4.1.1 and I can connect to WiFi without a problem, but I can't load any webpages. It's basically been rendered useless since the update. My computer(s) can still connect to the same network without a problem and load pages.
I can also access the modem settings from my phone, but I can't seem to get any connectivity. I used WiFi to update the software also.
Any ideas?
Thanks!
Did you flash the new radio too?

When you say you upgraded your firmware to 4.1.1, do you mean that you installed one of the Asian JB ROMs? Did you try forgetting the network and re-adding it?

Sorry, should have clarified, I just updated the firmware via the network. So a notification came up that there was an update available and I just did it that way.

Interesting, I did not now a Telstra update had been released.
If you tap the wifi connection, do you get an option to forget it? Have you rebooted your phone?

Telstra released 3.17, their JB update on Christmas Eve as planned.
Was your phone standard before you updated?
Eg were you running stock Telstra software prior to the update it offered you? You should not take over the air updates unless you are running standard software to begin with.
I dont believe anyone else is having this issue and many many people have updated.
Try resetting your router? Personally this sounds like a modem issue.
Forget the network and readd, while adding click advanced options and make sure your IP settings are correct for your network, eg DHCP.
Try resetting settings on either your phone or router?
Contact Telstra regarding the issue and if they have any solutions?
PS. on a second thought it sounds like DNS is not working. You should try to prove if it is your router or phone that is stopping DNS from working.
I agree that it does sound like DNS, can you check the DNS resolution or toggle the DNS servers.
Try dialing:
*#*#526#*#*
It is supposed to reinstall the wifi driver
I am having an identical problem with my telstra one XL.
I have tried 3 different modems so it is definitely not a modem issue.
I booted in safe mode to see if that would help and it didnt.
Dialing *#*#526#*#* didnt do anything, once i input the last star it just clears everything i dialed.

You are making this out to be more complex than it is.
Look you have 3 clear options:
1)Complain to Telstra (who will likely suggest #2 "data reset")
2)Do what others suggest to fix the problem, eg data reset
3)Do not use wifi.
Complaining to Telstra is the correct thing to do as perhaps they can get HTC to release a fix for it?
But a fix from Telstra is unlikely to be timely. If you want this resolved soon do #2 or #3.
Hey, I think I'm having the same issue. I'm sending this from my tablet over wifi, however my phone will not connect to the internet on the same network.
The network configuration is Modem > Router > Device, and I can access (log in, change settings, etc) the router from my one xl, but not the modem, nor the internet. Quite strange...especially as it is the same network over which I downloaded the JB update, so it clearly was working, but now isn't :/
Anyway, hope the extra info helps

[Q] stuck roaming after flashing

i flashed the new cyanogen mod stable 10.1.0.1-d2vzw and now my phone is stuck roaming. I have tried flashing back to stock and even got a new sim card and activated it still nothing any ideas?
welcome to the party
after doing research, i have seen most people are able to get service by odining back to stock then dialing the factory reset number...however, you will be stuck in roaming service
to fix that i'm yet to confirm...
one solution i have read about is using adb and doing an nvreboot as the nv ram is corrupt (probalby showing 0 for imei, none for eri, and zero's for meid)
another possible solution is using this tool

Did you try to flash a full factory stock rom? If you did then possible hardware issue. Full factory stock rom should bring back your wifi. I would do a full wipe, then flash full stock rom.

Go into safestrap do a factory reset, then boot to download mode and use Odin to flash full stock rom. This will wipe out your safestrap too. It will bring you back the orignal phone like you just purchased from the store. Just make sure you don't flash OE1 or OG5. This will locked your bootloader for ever.
Whenever I start to have wifi gremlins, I delete the folder data/misc/wifi and reboot. You lose your saved wifi and hotspot settings, but it seems to resolve a lot of different wifi issues.
