A few days ago I noticed I lost 4G. I still have 3G. Looked at APNs, mobile settings...look ok. I'm on clean rom 8. Any ideas on how to fix it?
1) ur username pretty badass lol
2)ur fone set to global and ruim/sim
3) if those are good. Try changing from global to lte/cdma/evdo. Reboot to see wat u get. Then change back to global reboot.

Tried all that. Nothing works. Could it be a sim card issue?
Are u on the 4.3OTA? If not i suggest back to stock (ics) then if still no work then get new sim.. If u go to corporate store they give u one for fee.

Help im from the philippines and i was unable to load my simcard on galaxy tab 7.0 plus came from taiwan is there any way to fix this..i was always in airplaine mode

Your baseband is unknown.. hmmm you should try restocking your tab that should reinstall ur modem. It might fix it. But before that check and see if ur tab still has an IMEI number.

A few months back my s2 fell in water and apparently I didn't let it dry enough before powering it own. When I did it came in and everything worked except reading the sim. And of course it had no imei number and no baseband. I had a friend check the hardware out after I tried to flash it back to stock and tried flashing the imei back with one of those boxes like the z3x I think that's its name. But it turned out there is a chip on the board that holds this information that got fried. But everything else worked fine. But I could forget using a sum on it again. So my guess was maybe that same chip on ur board might be the issue if u tried flashing back to stock and it didn't work. Or u could have that random efs corruption problem. But seeing as flashing a stock rom won't kill no one I would suggest u go back to stock and see what happens. And btw did u check and ssee if u sill have an imei number? And yeah u check by dialing *#06#

And about the imei number there are a lot of things associated with imei. For one its like ur devices ID there are some apps that are linked to imei like viber and things like that if I'm not mistaken. Without imei its like ur device has no identity. Its sorta how ur carrier recognizes ur device. So if u have no imei u have no phone. Or any telephony u have a tab with working wifi, Bluetooth and u can do almost anything but no mobile data and no calls. But lets hope that's not ur issue. Good luck man.

I have 4g Infuse, I recently flashed the current BeanStalk 20130318, with current gapps. ever sense my signal will work for a bit then when if I idle my phone for a hr or two the signal drops completely as if no sim was in it. I have tried updated apn's, updating modems, fresh wipes. Flashing older versions, anytime my phone idles it wont reconnect the signal. any ideas or help appreciated.
What's your imei say ,if it's symbols flash cm 10 then your rom of choice usually fixes imei problems
Sent from my SGH-I997 using xda app-developers app
Seems the Imei is indeed gone, tried to flash c10.1 with no fix but going to follow the imei tutorial here. http://forum.xda-developers.com/showthread.php?t=1873954 hopefull to fix it.
Hope it works out for you

Do all wipes flash cm10 most recent version boot up and then check imei then boot in recovery do all wipes and flash the rom you want I just had that problem going to slim yesterday and any time in the past this has always fixed for me
Sent from my SGH-I997 using xda app-developers app
I think I may have finally done it. I flashed the latest slim rom (vers 6) today, booted into the ROM and set it up. No problems. Then I flashed faux mainline kernel. I followed the instructions for the kernel install, and hit reboot as last step. The phone shut off and did not reboot. I am now unable to turn on, boot into recovery, or download mode. When I attempt to connect to the PC to try and ODIN back to stock, the phone will not connect to the PC. I have the latest Samsung drivers installed and have connected to my PC previously with no problems. I know I downloaded and installed the right version for my phone, I have flashed kernels many times before.
Am I screwed now? I have insurance on the phone, but really would like to get the phone back from the grave if at all possible. Any help offered would be greatly appreciated.
Never heard of the kernel ... Got a link to it???

Going through the history of my browser, it looks like I did a bone head and flashed a Nexus 4 kernel to my VZ GS3. Am I screwed?
Possibly ... Your kernel tells your phone what to do and how to do it ... If you can't get Odin to connect there's a big issues but I've never flashed a wrong kernel so research around a bit for more info ... You can't get into download mode or recovery mode??

Might need to either send it in for JTAG or spend the money to get the insurance replacement

This is the first time I have had this issue and have looked everywhere for help but am unable to find my particular situation. I have been flashing for a while and flashed the new PA 3+ and I lost my IMIE. I then odin back to I535VRLG1 4.0.4, build number IMM76D.1535VRALG1, hardware I535.10. I have tried the dialer code but it just factory resets my phone. i did however get my MEID back my phone info below

I have a EFS back up that i made from my previous GS3 that i had to warranty out due to power button issues. Can i use that EFS backup file on my replacement phone. They appear to be the same in all aspects, but i don't want to make my situation worse. Any advice? please help!:crying:
Each phone has a different imei so no you can't

Disregard last comment. You are going to need to inject your imei. If you have the box your phone came in, that would be great.

Imei is also behind the battery should be able to restore it using qpst I just had to do this. If you search for how to restore imei with qpst you should find a tut. Don't have a link atm.

I have odin back to ics 4.0.4 and then tried the dialer code to no luck, then tried a stock 4.1.2 and no luck. I did get my meid back doing this and my phone number is still correct. I do have qpst as i have flashed a few phones to cricket. Would just hate to screw up my replacement s3. I dont have original box as it was an insurance replacement so i believe its a refurb.ill look for a qpst instruction page but if anyone knows the link i would greatly appreciate it. I was able to get my text and talk back but still stuck in data roaming..... so i guess qpst is next step. Btw i did flash back to PA 3 4.2.2. Should i odin back to stock b4 using qpst??
fixed
Got it working after two days of messing with it. Used the samsung xda restore app, it was hard to find the .rar but i was able to simply type in g imei. Strange part is someone had mistakenly typed my imeid into verizon stating that it was lost or stolen so once i called verizon with the proper imei provisioned i was good to go. Thank u all for ur help!XDA is the best site for accurate feedback from people who care.
Woooo xda!

Well since I flashed Chaos kernel 8.1v I am able to connect to data only the first time since I wipe cache and dalvik. When I turn off the data and trying to connect it again I am unable to connect with my data. I tried 8.1v. 9.0 1 2 and 3 beta...and my problem persists

he doesnt have enough posts to ask there yet.
op, when you cant connect, have you ever tried to put it into airplane mode, then back?
I have chaos 8.1 kernel installed and no issues actually.
It would help if you give more information on your setup (ROM, method of flash, which ROM you're coming from, etc).
Wipe and fresh install would be where I'd start though.

Try dialing *#*#4636#*#*and go to phone information and set preferred network type or try modifying your apns, this kind of things happen to me very often and this is how i fix it, also try going to settings-more-mobile networks-preferred network type and change things there,
Good luck boy

Coming in late but I think T-Mobile network uses IPv6 data network.
So enable IPv6 option from NXTweaks and restart once.
