[Q] Mobile network not working after upgrading to ICS leak

I relocked my rezound and flashed the new ICS leak through fastboot.
The phone boots into the OS just fine, but doesn't pick up a network and says there isn't a simcard inserted
Okay, Im an idiot.
I didn't realize the back cover was an antenna. I put it back on and everything worked.
Happens to the best of us lol

Flashed to Energy Rom, now 3 days later, 4g is gone?

I hope someone can help me. I rooted my phone, flashed to the latest energy blue rom, it worked awesome. 3 days later out of no where, I lost my 4g. Its like my mobile network doesnt fully turn on. Wifi works fine though.
Has anyone run into this before? Anyone know a solution? I also tried to flash it to a different rom. Same problem!
HELP!

I think our radios (for the amaze) went down on T-Mobile cuz my gf on the mt4g still has 4g but mine went out an hour or so ago. And some people on Eclipze's ROM last data, too. Freaking T-Mobile...

It's a T-Mobile issue, nexus, gs2 and gs3 users are complaining of the same issue.
FYI guys. Data is down nationwide. This ROM is perfectly fine. Customer Care is flooded with calls. Connect to WiFi, you'll be OK for the time being. Do not stress that your phone is broken. Tmobile is broken.
A word from your friendly Tmobile Rep.

ah that explains it. Just bad timing for me I guess. Phone is all good now

very weak signal

I purchased a galaxy s3 international version about a month ago. The phone was working fine for about a month until yesterday, my phone is getting very little or no signal at all. also, when i connect my phone to my car, the phone will start calling itself. i performed a factory reset and the bluetooth problem was gone, but the phone is still getting very little to no signal. wifi is working fine. i called Rogers, my service provider. all they ask me to do was to buy a new sim card or remove the battery from the phone and wait. none of those helped... :crying: i'm kind of desperate here as i can't figure out what went wrong with it... my phone is not rooted or anything... if someone can help me out, i would really really appreciate it. :crying::crying:
Unless you are willing to start flashing modems to your phone there isn't much we can do for you.
Best bet is to keep pestering your carrier if you don't wanna root and modify your phone.

thx for the quick reply. So rooting my phone and flash a new rom is the only solution? :crying: is it possible it's hardware problem?
Not a Rom, not before trying modems anyway.
It may be hardware related, you should keep pestering your carrier for a replacement.
If it world fine before then chances are its a hardware issue or the cell tower near you is down.

i just found out in my mobile network setting under access point names, there's LTE ththering and Rogers LTE, could this be the problem? cus my phone doesn't have LTE maybe that's why? sorry, i'm not very good at phone stuff, it's just my random guess...
Is your phone International I9300 ????
Or are you possibly and no offense meant in the wrong forum ??##

Did you try with a SIM of other network? This may at least point out that either it is network problem or hardware problem.

I don't have another micro SIM... I tried flashing different modem and firmware. But none of them works... the phone is connected to the network, just the signal is extremely low all of a sudden... I had an software update 3 days ago, maybe that's why?

Atrix 4G ATT unlocked does not recognise and network in india

I got a ATT unlocked Atrix 4G for my parents in India. In US I used it with both ATT and t-mobile and everything was fine.
In India, my Parents have BSNL SIM and Atrix does not connect to the GSM network. Also tried using Vodafone SIM and the same issue.
Can connect to Wifi and add BLUR account.
Can some one throw some ideas on fixing this.
All your time is most appreciated.
Thanks
Ravi
Check what baseband you are using ? I have AT&T Atrix and it worked fine when I went to India. Even 3G worked fine.
If it is in the USA baseband flash radio again (only if u r unlocked).
If u r not unlocked flash the correct sbf (be very very careful) and ask people before flashing.

Check baseband version from aboutphone. Which firmware are you using?

Radio is most probably stuck to US only
Well something very similar happened to me when i first brought it here to india, it got stuck to us only frequency or something check by dialing *#*#INFO*#*#.
Now if you do not intent to unlock your bootloader and use a custom rom simply plug it in to Motorola software updater and re-install the latest update from there. It fixed the issue for me and effect is similar to installing a SBF but within more secure environment.
I have a ATT Atrix bought in US working for the last 1.5 years in India. Dial the chars between quotes "*#*#4636#*#*". Then under "phone information" check if it is in USA band. If in USA band, only way out is to flash the radio if your phone is having unlocked boot loader and is rooted else you need to flash using SBF. Be very careful while doing this. Do a thorough reading in this forum about flashing radios to avoid bricking your device.
Edit: Noticed that kapilchawla has already replied.
