[Q] Need help, bricked/nonworking WIFI after succesful sim-unlock

[crnkoj]

Hi guys,
i used a sim unlock code to unlock the ATT locked Atrix 4g, for use with a european sim card (mobitel, slovenia). it unlocked fine and i could call, but the wifi stopped working it just didnt scan/find or even connect to remembered wifis (home router), which worked perfectly before the unlock. so than i thought it might help to factory reset it, and now the problem persists and i cant even finish the wizard, cuz it wouldnt connect to the cellular (which we have 2g and 3g here) and the wifi has the same problems (so initially it finds all wlans, than after like a few secs it looses them all, i can turn off the wifi and turn it on again and the same thing happens). so i am wodering if anyone has any idea how i could rescue the phone ...
thanks in advance

ok guys i did a hard reset and put in a nonworking sim (doesnt connect to network) and i got the wifi back to working and managed to activate motoblur again. so after that ive put my working sim card in again (3g+ hsdpa+ able), and the wifi stops to work again/behaves the same as i described before. terrible ... anyone has an idea how to fix that ?

ok, more problems, now after ive put the working sim inside and the wifi stopped working, i tried with the nonworking sim (that wifi worked great before with), and the wifi isnt working with the sim it was working before either and even if i try without any sim it doesnt work... ill try with a third sim now and if it wont work ill hard reset it again

Same problem

I have the same exact issue. Anyone know what to do? I can't imagine that this is "bricked" because everything else works fine... thoughts?

where did you guys get the unlock code from?

Actually, I have a similar problem. After entering unlock code the phone accepts my SIM card, but I cannot activate 3G connection. GSM is working, try to call my other phone. APN settings are correct.
In the "hidden" settings menu (*#*#4636#*#*) I cannot chose between radio bands, but only the USA radio band.
Any ideas? Will I need to root it or even put a custom ROM (if it exists)?

So you guys used an unlock code from someone other than the carrier and are now having issues?

Wish I could help on this one. If you used an unlock code from someone other than the carrier, I would contact motorola support.

If you used a piece of software, I would wager that the software broke something and you might as well warranty return it for another.

Don't be offended, but I don't think this is the case. AT&T locked their phone to their network with standard network code (as seen in many other phones for years) so that "alien" SIM card would not work. But, additionally, since the AT&T has some value added services on their data plan (like wifi tethering) they made some accommodations (read: locked parts of the android configuration).

I am not a developer, this is just my guess, but it seams sane and probable.

No offense taken. This is why I asked about a program. Using an unauthorized code to unlock it may over write a.setting or file. Its also possible that someone broke something using adb.

Best solution, warranty it and try again

can you guys tell us what website you use to get your unlock codes from so we can avoid them? thanks

man.. this forum is dead.

even the OP stopped coming here to check his post :/

Based on your replies, I'm guessing you've never unlocked a phone before...

Unlocking a phone to be used for a different carrier affects nothing else but the ability to only use the SIM Card of the carrier you bought the phone from.

To unlock a carrier-locked Motorola phone, you simply need a "Network Unlock PIN" which is an 8 or 16 digit code that you enter to unlock the phone to any network. There is no software installation ivolved in the process.

A 3G issue will occur when your carrier doesn't support the 3G bands that the Atrix supports. Which would be: 850/1900/2100. If your carrier doesn't use any of these bands for their 3G network, then of course you are going to have 3G issues.

The Wi-Fi problem that the OP is having may be as simple as him having an antenna QA issue. But it could never be the Unlock Code.

Unlocking your phone and using another carrier other than AT&T has nothing to do with Wi-Fi issues...

I got my unlock code from cellunlock.net. It unlocked my phone just fine. Don't use that as a reason to avoid cellunlock.net. Unlocking is unlocking.

I have swapped back and forth between my prepaid sim and My AT&T SIM about 5 times so far.

WiFi disconnects almost immediately when I try to connect with my prepaid sim inserted, but I can make calls. (Atrix also displays H+, which can't be right)

With my AT&T sim everything works fine, solid as a rock.

I may do a factory reset to test things, but I have a feeling it has something to do with drivers or the network stack on the atrix, or perhaps because my prepaid sim has no data plan. It certainly isn't a hardware problem with the antenna. I am afraid to do a factory reset on the atrix while I am out of the country, considering that it requires network access to unlock itself.

To the original poster:

When you put a non-connected SIM into the phone, if you do a power reset again, the wifi comes back up solid again.

Also, is there some way we can request a merge of these two threads?

It really is quite weird...

I was merely suggesting that it could be a multitude of things, but never the unlocking code or the process of unlocking itself.

Also, it can't be your SIM because your SIM has nothing to do with Wi-Fi. If we were talking about GSM and 3G then SIM cards come into play. Other than that, no way.

Have you tried using the phone without a SIM? Do you get the same problems?

I agree that it has nothing to do with the SIM or unlocking.

I just tested. I get the same problem with no SIM inserted. Screw it.. doing a factory reset and seeing what happens.

Edit:

Still does the same thing. But now I have to re-activate app sideloading.

Also, you can reactivate over wifi, which is nice.
