[Q] No 3g Internet access on Att Xperia x10 - XPERIA X10 Q&A, Help & Troubleshooting

So I recently flashed my att xperia from 16. to 2.1 and I've tried all the apn settings that you guys provided but none of them work. Still can't get on att 3g.
I did the automatic method and it comes up with 2 apn. The ones that my x10 pulled up from att are the following. One is MEdia Net and the other MEdia Net MMS that's it no more. My wife also has an x10 but is still on 1.6 and hasn't flashed hers to 2.1. When I go into her apn names her phone only displays one called ATT. I even copied her apn setting and deleted the other ones on my phone and I still can't get 3g not even an E or H like some people on the forum get post flashing to 2.1. Can anyone help. Please don't give me the common apn settings because they don't work. Someone who has fixed their 3g after the 2.1 flash help!

Was this the official update or the generic or world? did you do a battery pull? putting in the apn setting is all I needed to do, mind you I am on the nordic.. perhaps flashing it again will solve the problem.
Good luck!

download the firmware from this link and re-flash your phone. I am on AT&T and i used the same link to flash. everything works fine for me. In fact i am getting 'H' network on AT&T which is faster than 3G.

this is the same as mine
it should just be in the apn settings no. I don't want to reflash because everything works great except 3g. Here's the the firmware i used world.x10a_1.0_2_1_A_0_435.ftf.
Model number
x10a
Firmware version
2.1-update1
Baseband version
2.1.54
Kernel version
2.6.29
[email protected] #1
Build number
2.1.A.0.435

Everything sounds right. Try repair software on SEUS or PC Companion instead of flashing the same downloaded firmware. Don't worry, it won't put you back to 1.6, and it will give you a fresh install of official SE firmware. If that doesn't work it might be a hardware issue.
Also: on a side note. Did you use the flash tool and firmware from xda and unbrand, or did you get an official SE update from SEUS or PC Companion? I'm only asking because someone posted a comment somewhere else saying he thought AT&T was finally releasing the 2.1 multitouch update.

Y don't you call AT&T and ask them to resend the settings over the network?
You can just say that 3G stopped working for no reason.

I did use SEUS already and it did upgrade but still no 3g. I used the flash tool provided by Binary in the forums. Why would it be a hardware issue when it had 3g on it's original 1.6 att droid? It happened after downloading 2.1.
I have the x10a_1.0_2_1_A_0_435.ftf with mt already in it. What are your apn settings for att? Should i delete the MEdia Net and MEdia MMS and manually enter a new apn for ATT like on 1.6 att phone that i didn't fash yet? Heres what auto search put in.

Should I delete the other 2 and enter the Att one just by itself?
they won't know or care that i flashed my phone?

You don't have the app APNroid running or some other data restriction running like a battery saving app or task killer, right? Even if you mess the apn up it will correct itself to media net and media net mms. Since it even downloaded the settings means something is working. Try settings / wireless & networks / mobile network / network operators / search mode / network search/ automatically search. It will search for a while, then it will give you 3G AT&T, 2G AT&T DR, and 2G AT&T to choose from. Select 3G and let it register. If auto doesn't work try manual network search. Also, try turning wifi off.

I think repair software will work. If not, then do what I said in my last post with register network operators. That isn't the same thing as apn settings. Those seem to be correct. Let me know how it goes.

still no H after repairing with pc companion.
it pulled up 3G AT&T, 2G AT&T DR, and 2G AT&T. I picked the 3G ATT and it registered but still no internet access on 3g. It has to be in the settings then. How do I check if APNdroid is running?

Settings: under mobile network "data traffic" should be checked and network mode should be set to "GSM/WCDMA preferred". Media Net should be selected in APN. Turn WIFI off. Register network with operator. Reboot.
Uninstall Apps: APNdroid is an app you would have downloaded yourself. If you have restored your market apps, uninstall any task killers, app managers, data, wifi, or battery apps. Make sure wifi remains off. Reboot.
If it does not connect after all that, it's probably AT&T not you. Especially if you can send/receive yourself a mms. Call them and tell them to test your data connection. Don't say anything about unbranding or updating. They don't need to know. Especially if under warranty. If they can't fix it, they won't be able to tell anyways. If they do fix it, don't give them time to notice.
I hope this works. I know how frustrating it can be. Last piece of advice, it is almost always something simple that you're missing. Let us know. Good luck.

try this http://www.youtube.com/watch?v=wacg-dsx9ew&fmt=22
thats the .26 firmware tho. the apn settings are in the desciption.
it also uses flashtool so you should know how to do it.
then if u want .435 just plug into sues and update.

The APN settings really don't matter as long as you have an APN wap.cingular.com. I've tried all different APN settings, including yours, and the phone always corrects itself to Media Net and Media Net MMS.
I really think it's AT&T that needs to re-establish network connection. It's not recognizing the SIM card or something like that. It happened to me before.
Edit: So what happened when you called AT&T? I'm guessing that was it by your absence.
