[Q] 3G Not Working After Flashed SBF

Hey guys,
I'm a noob here, sorry that this is in the wrong section.
I recently flashed my phone to the 3.4.3-11 "Froyo" 2.2.1 Android SBF, and lone behold, my 3g stopped working. I've tried factory wipes/resets, reflashing sbf files and nothing seems to work. Any help would be greatly appreciated. Thanks for a great forum guys.
GoldenStateTy

I'm having the same problem!
I flashed the 2.3.4 UK sbf to my device and now 3G will not work!
I'm thinking it's not working because I'm a US customer and the sbf is from the UK but, I'm not sure.
I've also tried calling customer care and had them reset the server my phone is on they said it would take up to 3 days, it's been 10 days, and nothing... still.

You wouldn't happen to have one, would you?

You need to get ' defy baseband switcher' from xda or the market, set it to your region and reboot.
There is still a chance you may need to find the apn's for your region and enter then manually I they will be the same for any android device in your region and on your network, search xda.
When you have set them, get apn backup and restore from the market and back them up so you can just restore when you flash another rom.
Alternately, cm7 includes apn's for every region.

[Help] Phone won't detect sim. Unknown Baseband and IMEI

So... I seem to be having the efs corruption issue with my co-worker's phone. I've been searching all over and have found how others have solved the problem, but it seems that our nv_data.bin is not located in our efs directory.
Does anyone have any idea where these files are? I need to check the last modified dates of their backup files to see if I can restore them >.<
Any help is greatly appreciated!!

Bump.. If anyone knows where these files are this could help us from running into the corrupt efs problem that many people have had. Usually backing up your efs prevents your phone from becoming unable to function as a phone.
I do remember reading something about our unlock code not being present in our nv_data.bin.. And when I check my efs folder in both my, as well as my co-worker's phone there is no nv_data.bin so maybe it has been relocated??
Anyone with knowledge on this subject.. your input would be greatly appreciated! I'm also gonna read over the unlock threads to see if there is any relevant info there.

I am having this problem now, I know you posted this over a month ago, but please tell me you know the location of the backup files or any other solution for this?'
Thank you,

[Q] T989 - Baseband and IMEI Unknown
I have searched and read many threads already. I understand the i9100 uses a file called nv_data.bin and requires its .bak file for a fix.
But, I dont think the t989 is the same because these files dont seem to exist, or at least not in the locations the threads for i9100 state. I am wondering if anyone has had this problem and/or how they fixed it. I know it was caused because of trying to unlock, but I'm looking for a solution.
Thanks!

just buy one of those $20 online unlock or go to your local phone kiosk to have it unlocked
any one with a machine to unlock Samsung phones can get this phone unlocked easily
there's no software unlock yet, as you have found on your searches

I have T-Mobile and don't really care for the unlock, it was a mistake. At this point, I just want to fix the unknown IMEI and unknown Baseband issue. Because of this problem my phone cannot get a signal... Will performing a machine unlock fix this problem?
Note: When I type in *#06# the response is not my IMEI number. It says "null"

You can try to find someone locally with a SPT Box2. This unit can flash, unlock & repair IMEI on SGH-T989(d). I was gonna pick one up, but they are like $250 yikes !!

What does the (d) stand for?
And, how can I make sure this never happens again in the future? I know there are backup options out there (CWM, Nandroid), but are there any that make a complete clone of the phone's image? In case I mess up the efs or IMEI files again I can restore and be ok.
Thanks!

is hard to say, we have no idea where is the real IMEI information is being stored in the new models, but is no longer in the old EFS folder

I wonder if the new Galaxy Nexus has its IMEI files stored similarly. If so, we can join forces with that forum group.

If Android is not mounting your firmware properly in the system this will cause no baseband and no imei detected. i would try and flash the stock rom to make sure.

Did it twice, the stock rom, modem, and kernel.

The radio (modem firmware) might have got corrupted if somebody tried to flash international GS2 ROM or modem.
Try to flash only the Radio (KL1 is the latest for T-Mobile) via ODIN (use PDA slot).

Would the KL1 work any different than the older one? I tried ODINing the original one, and it didn't work and increased the count so I didn't try the KL1.

I just got my replacement phone yesterday for this same problem. Flashed the stock kernal, and also the modem just to be safe and nothing would fix it. From what I know its just a hardware issue, not software. I was chatting with samsung and t-mobile people about this trying all kinds of fixes to nothing left but hardware defect.

[Q] Problem with no iberian roms

good morning
I have a problem.
I am a customer of a virtual telephone operator called "Yoigo". It uses the coverage of other companies when their own fault. Because of that, if I do not install the version "Iberia" I need to turn on data roaming. The problem is closer to a frontier. You can then connect to a foreign network and ... they charge a lot.
I have tried to fix it by reinstalling the "baseband" of version iberia ftf using "flashtools" but does not solve it. Is there any way to change "Rom" custom and combine it with ftf Iberia?
Here I add the 4.0.3 ftf "Iberia" [note: I cannot put the link :-( ]
thank you very much

I can not put links because I'm new. If anyone is interested in the firmare version 4.0.3 ftf Iberia say it. I can not send private messages either.
It is very frustrating

If you already got the "Iberia" and still asking I guess you are using another one, may be a custom one and could not solve the roaming issue.
May be there is something in the build.prop that changes that configuration.
Compare the "Iberia" build.prop with the one in your rom to find differences that could relate to the issue.

I will install the ftf of "Iberia" and make a copy of "/system" and build.prop, then I will compare with the modified ROMs. It sure is something simple to change, but we need to know what is.

[Q] Can't Connect to Mobile Network after Custom ROM Flash

Hi all, so I'm in quite the predicament. I can't seem to reestablish a mobile connection via Verizon at all since I've overwritten the stock ROM with Cyanogen. I have Inc2, now loaded with CM7, awaiting some help.
First I unlocked the bootloader and flashed CWM Recovery.
Next I flashed Build 4 CM10 http://forum.xda-developers.com/showthread.php?t=1934288 <--check it out here.
I couldn't establish any network connection whatsoever. So i wiped and flashed CM9 with the hopes it would be more stable. http://forum.xda-developers.com/showthread.php?t=1932573 <--again check that one out.
Again, no network connection. Lastly, I reverted to CM7 (because it was the last stable release directly from Cyanogen). http://wiki.cyanogenmod.org/index.php?title=Vivow_Info <--looky here.
I've searched far and wide, trying everything possible. From simply switching on/off airplane mode to manually typing in the Verizon APN. I just can't establish network connection now...and the kicker - I forgot to backup the stock ROM so I'm currently stuck. Please help
This thread may be of some help. Didn't do me much justice however. http://forum.xda-developers.com/showthread.php?t=1691017

Bumping. Somebody please help...Also if anyone has a stock ROM they could share, that'd do fine as well. I'm curious if stock ROM would re-enable the radio (if that's the actual problem).

Have you tried changing your mobile network? Settings > more> network mode

Been there. You can try different radios from here, but BE CAREFUL. Take the following precautions:
Because you're on Verizon, only download 'x.x.01.xxxx' radios.
After putting the ZIP file on the SD card, verify the MD5 hash to ensure the file didn't get corrupted during download or during transfer to the SD card.
Plug the phone into your charger before installing. You don't want it shutting off during install.
Don't flash the same radio that your phone already has installed.
If all else fails, try the stock 2.3.3 RUU from HTC. If you can find a working download link to that, please share.

I've tried everything in the books. Manually setting my APN according to the Verizon settings. Also did trial and error booting and rebooting each network type to no avail.
A few things I noticed in the CM9 ROM (maybe bugs?):
The preferred network mode typically defaults to GSM/WCDMA upon reboot
The APN I create often disappear upon reboot.
Mobile Networks>Network Operators will either search endlessly or sometimes find both AT&T and T-Mobile as options, both of which won't actually connect as I have a Verizon SIM.
And in response to Slinkwyde:
To verify the MD5 hash, what needs to be done more specifically? (I'm learning as I go ) Did flashing a radio do the fix for you? I'll try this suggestion and post results.

Yes, verizon sim card. I'm in the USA. And I believe I am supposed to be using GSM but I don't fully comprehend the differences between each type. However I have tried setting each type in system settings>mobile networks with no data showing at any point.

Yes, flashing a radio worked for me. The simplest way would be to use an MD5 checker app. Use the app to make sure the file on your SD card matches the MD5 value given in the radio thread I linked to.
One more precaution: Don't ever flash the same radio version that your phone is already using. That caused problems with the original Incredible and might also cause problems with the Incredible 2. To see what radio version you have, go to Settings and look around in About phone, Phone info, or something to that effect. "Baseband" is another word for radio.

Short version: For Verizon, you want CDMA with EvDO.
Longer overview: CDMA vs GSM, and what it means for the Incredible 2
Verizon Wireless and Sprint use CDMA. AT&T and T-Mobile use GSM. CDMA is popular in the United States, but around the world GSM is far more common. All GSM phones use SIM cards, but most CDMA phones don't. The two kinds of CDMA phones that do have SIM cards are world phones (phones with both CDMA and GSM) and LTE phones (faster data speeds).
The Incredible 2 is a world phone (without LTE) and comes with a Vodafone SIM for overseas travel. This Vodafone SIM also has Verizon Wireless branding on it. The Verizon Wireless company is jointly owned by Verizon and Vodafone, a European carrier based in the UK. Verizon world phones have to be unlocked to use AT&T or T-Mobile, because Verizon doesn't want their customers switching to a competitor.
SIM cards make it easy for GSM users (not you) to use their carrier account in another phone. They can just swap the SIM. For CDMA carriers (such as Verizon), swapping service to a different phone requires contacting the carrier.

You don't need the sim card at all then, you're CDMA. If you're not on it already i would recommend flashing the latest ics firmware, it can be found in the ICS leak ROM thread posted by nitsuj17 , it includes the newest radio

Okay so what you both are suggesting are to just install the firmware, assuming I am already running the CM9 ROM? Because the firmware includes the radio. And this is done by renaming the firmware to PG32IMG and flashing it through hboot? Would this be an easier course of action than installing a radio alone? My phone is S-ON and if I'm correct, S-OFF needs to be active to install a radio.

Yes, you can install the firmware to get the radio, and the file name needs to be PG32IMG.zip for hboot. S-OFF is generally required for this sort of thing, yes.

I'm currently trying to downgrade Inc2 so I can S-Off in order to flash either new firmware or radio. I am following this http://forum.xda-developers.com/showthread.php?t=1726134 and cant seem to download the necessary RUU 2.3.3 for Inc2. It seems as if the downloads link is dead. Can anybody link to such a file? I cant seem to find one anywhere.
EDIT: Found a stock (or as close to stock I could find) ROM for INC2 >> http://d-h.st/I2g

Also, I may have a potential reason as to why I'm having this ***** of a problem. I originally unlocked bootloader using the HTCdev tool. At the time it was my understanding that the process did not matter as long as the results were the same. However it seems now that using their tool makes it so you can't flash radios and need to extract and separately flash ROM kernels. So does this mean flashing any of the CM ROM's I tried never included the radio portion?
Just stabbing at ideas. Feel free to verify/call me out.

Roms NEVER include a radio, its always separate. something weird has happened to you, I'm sure flashing new radio would fix it for you but you're dev unlocked which is gay Lol. When you flashed the cyanogen ROMs did you pull kernel and flash like you were supposed to, if not i can't believe you got it to boot but that may be a problem also.

If it helps, here is the process that I have used every time I flash anew ROM, working every time (excluding the radio of course.http://www.youtube.com/watch?v=ujFWZbgj6bY
Because I HAD (I actually just reverted back and am currently getting S-OFF to flash a radio) the HTCdev unlock, I manually booted the boot.img after entering recovery and wiping/formatting all the necessary things. Skimming the video might give you a better idea.
However I'm now hoping S-OFF will allow me to reroot, flash CWM, CM9, and of course a radio. Currently in the process of trying to run Revolutionary.

SIM no longer recognized as being inserted; IMEI not visible in software

Firstly, my apologies if this issue has been solved before here, but neither a search of the forum nor the automatically found "similar threads" based on the title have revealed such a problem as this.
Last night, I attempted (and eventually succeeded) at reverting my SGH-I747 to the stock 4.1.1 ROM, with the intention of subsequently installing the 4.3 and 4.4 OTAs. However, I was unable to do this because the phone behaved as though no SIM had been inserted, despite the fact that one had. At various points throughout today, I've performed factory resets, re-flashed the 4.1.1 ROM, and gone back to CM11 (under which my cellular connection had been fully functional up until last night), all with no results. My next thought was that the SIM card itself had somehow broken*, so I looked through AT&T's process for ordering a new SIM. However, I am unable to view the phones IMEI (which is required for such ordering) through software. Obviously, I could just pull out the battery and look at the IMEI there, but I worry that the lack of ability to view it in software is indicitave of some sort of problem with the phone.
My main concern is, is this a problem that I can easily solve? Or have I irrevocably screwed up my phone's SIM slot (or some other piece of related hardware) which I need to replace in order to recieve mobile communication?
Any help much appreciated.
*Before anyone asks, I am unable to test the SIM in a different device, as neither I nor anyone I know has a device on AT&T with a micro-SIM slot whose phone I can borrow for that purpose.

Before you try the NV re-write, I would suggest you first check to see your modem hasn't been corrupted. Go to settings and see what is showing under Baseband version. If it reads <Unknown>, then you may be able to fix it by flashing the 4.3 MJB modem. I don't know what procedure you used to downgrade from 4.3 to 4.1.1 without hard-bricking your phone. It is indeed possible to downgrade the ROM only without downgrading the bootloader. However, the 4.3 bootloader and modem are in a tight and unbreakable marriage so if you downgrade the ROM and modem, you would end up losing your modem and consequently all cellular functioning even if you didn't up in a hard brick.
If your baseband version is indeed showing as unknown, then you can go to the link below to download the modem and flash via custom recovery ....

I should clarify. I downloaded the file using my laptop, then connected the phone to the laptop, and moved the file to the root of the external SD. Using a file explorer app on the phone, I can see the file in that location, as well as several flashable ZIPs which I've put there in the past. However, when using TWRP to select a file to flash, I can navigate to the root of the external SD and see (and flash, if I wanted to) the other files, but not the .bin, presumably (though it's possible - or likely - that I'm wrong here) because TWRP expects all flashable files to be .ZIPs, and so doesn't display files that don't end in .zip. So, the question is, in order to flash this file, do I need to change the extension to .zip? or flash a different custom recovery? or use some other method for flashing altogether?

I'm not so sure what file you downloaded but it should be a zip. In order to flash, you need a zip with META-INF folder in it (to put it simply).
Here's what you need: http://forum.xda-developers.com/showthread.php?t=1831898 (The MJB one).

The baseband version is shown as "unknown"
I downloaded the file and moved it to the sd card in my phone, but the file doesn't appear in TWRP's "Select Zip to install" dialog. Does the file extension need to be changed? or do I need to flash some other recovery?
Thanks for your help!

The file should be a zip. Just checked the link I sent you and I'm just seeing it's a*.bin file. You could try the one from the link forwarded by BWolf although this appears to be for CWM.
After this, you may also want to see if you won't be better off going to full stock 4.3. I'm not sure the hybrid firmware (4.1.1 ROM with 4.3 Bootloader/Modem) offers any real benefits.

Here's a TWRP flashable zip for the modem if the CWM doesn't work.
