No signal

Hey everyone i recently install a rom posted by a user at the following threat http://forum.xda-developers.com/showthread.php?t=2033132 both mine and my gf's s3's, my install went flawlessly but hers had an issue. the signal was very weak, at first we thought it was a reception problem cause some text and calls were going through (and when i say some i mean almost none). then i went poking around and saw the imei was showing 0, the phone had been rooted with cwm installed on it, so i used so of the tools and the tutorials i found on these forums to restore the imei but still very weak and losing signal, on reboot of the phone there is no signal at all, so i kept on reading in the forums and tried to flash a modem but nothing still, then installed cm10 stable and still nothing finaly i gave up and installed stock rom unrooted the device, used triangle away and all that and still nothing even installed the latest ota updates and still nothing, im at the end of my rope lol and my gf is about ready to kill me, any help would be greatly appreciated . im with bell model number is i747m, the base band that it currently has is i747mvldlk4

[Q] Dirty Unicorn flashed over Stock Rooted, what modem?

[[SPRINT]]
So my dad trashed his E4GT by dunking it in a river. Then dropped it at work cracking the screen. Gave him my old one. Had a hell of a time getting it programmed to his line, but I got it. eventually had to flash the One-Click Stock (JB) odin to fix an issue where he could not connect to WiFi. After that, flashed Dirty Unicorn, and all was good. Or so we thought (we were in range of an Airave). Seemed he no longer had any reception off of the Airave. After much searching it seemed possibly due to the fact that the phone refused to leave WCDMA mode. Long story short, I fixed the issue by starting back on Stock Rooted (JB), getting fresh PRL and Profile after wiping EVERYTHING i could find, and then flashed back to DU. He was totally fine for two weeks. Now all of a sudden he again has no signal off of the Airave. He is in a bad reception area, but when it is working properly he gets enough to call, text, browse a bit, etc. But when it is acting up like this, he cant do anything at all off of Wifi and/or Airave.
TL;DR
Going from stock rooted JB to JB Dirty Unicorn, would that cause modem issues (being that the stock rooted most likely has a JB modem, and you arent supposed to use JB modems on JB Dirty Unicorn)?

ICS modem for DU..pretty much all aosp ROMs ( ICS to jb )..the latest ICS modem is FL24. Flash that modem or another ICS modem on the phone. Then do the temp boot to upgrade prl and profile.. If you're on stock again you can flash the modem and update the prl and profile.. Then flash DU.. Making the move to DU shouldn't have messed up the modem..if you did the above..

Yes, i know that. But his phone worked fine for 2 weeks so I wasnt sure if that was the culprit. I have some time before I will have an opportunity to *try* to walk him thru flashing an ICS radio himself >.> so I figured Id ask

No I hadn't flashed an ICS modem. Everything you said the first time was correct. I went straight from JB Stock to DU. Spaced out on the modem because I was in a rush to get everything working. And when it actually did work fine for 2 weeks and now stopped, it threw me off.
I am going to see if tomorrow I can walk him thru the One-click to install FL24

No need for a one-click.. Just have him download an ICS modem from rwilcos repo..( zip format ) and then boot to recovery and wipe cache and dalvik cache. Then flash the modem.. Next time you have a moment you can do the temp boot to update prl/profile

The One-click is nice and simple though. The less steps the better, my dad isnt exactly a whiz with current tech. I already have both downloaded on my laptop in case he doesnt have the confidence to do it himself

You the boss.. But there is no way..hooking you're phone to a computer is easier than flashing one zip file from you're phones own recovery.. In my opinion.. Less steps my way , too. If you need any help with flashing a modem from a phone or you're dad does. Just hit me up. I'd be glad to help.. I finally have my dad texting and my mom on a rooted huawei ascend 2..although I did all the heavy lifting for her,she's starting to get it..lol.

Just ran thru installing the ICS modem. No change. Cant update the PRL or Profile on DU of course, though. Updating the PRL and/or Profile necessary for any change to take effect?
Also JFYI, yes I know what it will take to update them, just wondering if having not done that yet is what would be causing there to still be a lack of signal

This is where I'm not sure, everybody says to update..but I have went without,but I did notice my signal bouncing around..... But I'm in a very good signal area.. I would say an update can't hurt...FYI...I get the best signal on gb27.. On touchwiz...of course. There are some good tw Roms out lately..too. You could always go back to stock to see if its the rom/modem..Then work back to cm/aosp or tw... This signal stuff is funny to mess with..what works for one might not for the next.. I can't remember what carrier you have but a signal repeater might be a choice..

Sprint. He has gotten signal where he is before in DU (and that was with a JB modem, no less) for two weeks. It was low signal, but it was signal no less. Our only option is to get the phone working normal, a repeater will not do as he has no signal at his house, at his job, or anywhere within approx 60 miles of where he lives. Normally he has low signal, but atm he has zero. I am currently waiting for his download of a Stock Rooted rom to finish so we can flash that (which I know for sure will give him signal) then flash the ICS radio, update PRL and Profile, and then try DU again. If that does not work I will just have to have him stick to the Stock Rooted JB rom, since we know he gets signal on that.

[Q] Band Handover/voice network issues

So I have been waiting patiently for the 4.3 update to roll out to me OTA with hopes that it would fix my issues but my phone has been saying download interrupted and so I have gone back to completely stock and triangle away to get my device status back to normal but it still wont let me download. When looking around for other possible causes I saw that my build number is JRO03L.I747UCDLK3 which comes up as a build number for a nexus 7, the correct build number for my att should be JRO03C. I have no idea how it got that way but I am wondering if the person who bricked it might have put the wrong version of the bootloader or some other part of the firmware on and it somehow didn't brick but is detecting a conflict and not letting me OTA. Or that is what is causing my cell network issues as well. Wanting input from a a few devs as I am not 100% sure what the first part of the build number represents.
Ok guys and girl, I am having a really weird issue with my Att Gs3 that I wanted to see if anyone could help with. To start off a little bit of background. I Hard bricked my s3 in August, sent it for tag and got it back working and stock with no issues. All I did was root the phone for fear of messing it up again but it was running all stock without problems for over a month since the unbrick. About 3 weeks ago I went out of town within the state but a ways away, I was talking on the phone with a co-worker right before leaving town. At some point that evening I get a a text from my wife asking why I was ignoring her calls, I had never received them and according to my phone was in the middle of prime 4g lte zone in San Antonio but I was apparently only receiving that lte signal and the phone was not switching to the voice network on 4g to make or receive calls, I was even able to voice chat with my wife but I couldn't just call her normally. After returning home I was still unable to make or receive calls unless it was right after a restart and I had to try about 15 times, so I called att and tried all of their bs which didn't make a difference at all. Looking around on the internet I found the number that you can put in to get into service mode and switched it to gsm or wcdma only and voila I could make calls again. The only problem with that being that I travel within a city for work and move from 4g to 3g to edge all the time but if I have it set for wcdma only then I have no signal and have to take the time to pull up service mode to switch back and forth. So I tried going back to completely stock again by resetting/ formatting all and flashing the stock rom via odin, my issue persisted so I also decided to flash synergy rom (which I was running prior to the hard brick) and then intergalactic because I saw the fewest problems with it to no avail. I have flashed each stock modem new and old which made no difference at all. Today I was messing around in service mode and found an area that was called handover, in that subsection you have the option for checking the phones ability to switch from gsm to wcdma and back as well as to hspa, when I select any of those options I get the message "temporary block due to build e" or " temporary block code".
I was wondering if anyone has any ideas about what the possible problem could be, imei, modem hardware, or a stubborn stuck modem firmware setting.
I was also wondering if anyone had any experience with figuring out how to re-enable handover because that is where I feel my problem is, either through adb or any programs that let me force change the settings, I would also be happy if someone knew how to turn of only LTE and have both gsm and wcdma on at the same time.
Any help would be much appreciated, I have tried everything I know how to do, but am to the point where I am forced to look at new hardware because my wife is pregnant and I really needs to be able to get a hold of me any time.

if you have CM recovery or TWRP you can go back, wipe everything even twice could help, then flash a stock rom reboot and see what happens
if that doesnt work go back to odin and install stock firmware 4.1.2 from Samsung but again you have to wipe data/factory reset
3rd if that doesnt work, try to restore your EFS folder/files using this link http://forum.xda-developers.com/showthread.php?t=1725839
that link has everything, how to fix it, anything you need to know
BUY a new phone or use a different phone if all the options above fail

The backup restore/fix imei and data restore tools link doesn't go anywhere, does anyone have a link to the restore tool? The only version I can find is for the non us version of the s3.
I did at least use the tool for the 9300 to find out that I have some 000 for s/n and other numbers (see attachment)
is there a patch out for us gs3's to fix this like there is for the i9300?

I think I can help, I just need to pull up some files and I might get you the software or program I used to back -up and restore my EFS folder/files
Even fix it, so plz hang in there........will report back later on

Thanks a bunch, I am still trying all kinds of stuff but I feel pretty certain that the problem lies with a messed up efs and I don't think I have a backup unless doing a nandroid covers that as well, which I am not seeing that it does. Any further help is appreciated, is this something that a local cell repair shop can typically fix or is this a possible new phone situation?

this is the software/programme i used to back-up, recover or even fix my EFS files (if they are corrupt and can be used) NV items reader writer
type it on google and pretty sure you will find something , try different links and again am sure you will find a download
have you tried flashing the new 4.3 stock firmware and modem follow this link for everything http://forum.xda-developers.com/showthread.php?t=2498233 or you can wait for AT&T to release the official 4.3 firmware and that will be 100% satified to be stable and will fix all your EFS/IMEI problems FOR GOOD :laugh:
i have the NV items reader writer software that can fix your problems but i dont know how i can share it with you without breaking any rules
ULTIMATE/final solution send it to MOBILETECHVIDEOS and will fix it like its nothing, take it to samsung and have to play some ball, or BUY A NEW PHONE
tried kernels (idont think it will make any difference) but its good to check

I have tried all the other versions but will try the 4.3 what's the name of that software so I can try and find it or of you have drop box you could pm me the info and get it to me that way . In the meantime I found an fusion 2 for 38 bucks from att so I can get calls for the time being.

[Q] Help with modem

Hello, I used to own a GS3 and had it rooted and everything just fine, but I sold it when I broke the screen. I recently purchased a used one off Ebay and want to get back root and custom ROM. The seller had the firmware updated to 4.4.2 stock and of course it is bloated to hell. I managed to get the root installed, however I flashed a new rom and modem and now have no network connection. I have tried modems LK3, MJ2, and MJB and none have worked. Also, somewhere down the line I managed to break the wifi, as when I try to turn on wifi it instantly switches off.
I remember it being very easy to root back when the device first came out, I was on a Galaxy Nexus previously and everything. Another thing to note, once I got the root installed I made a backup in cwm and even restoring this backup I have broken modem and wifi. How ****ed is my phone?
EDIT: I managed to find the elusive NE4 modem that was not in the "all modems" thread. This fixed my issue. Feel free to close thread mods

Closed at OP request.

Screwed phone up after trying to flash custom ROM

I've got a lot of problems actually. I have a Virgin Mobile Galaxy S3 (SPH-L710) with 4.4.2 that I rooted yesterday, but I didn't back up the stock ROM before trying to flash Cyanogenmod. I lost data, eventually I lost wifi, and then I think I bricked it trying to flash various things to fix it. I then tried to flash stock firmware but ended up with a phone that thinks it's on the Sprint network (still no mobile data). I haven't had any luck trying to find stock ROMs and kernels for Virgin Mobile (assuming that's what I need to fix it?). I'd like to be able to go back to the out-of-the-box unrooted ROM until I can do more research.
I'm completely new to the entire process and clearly got in over my head. I hope you guys can point me in the right direction.

Sir,
Please wait until mods will move this thread to the device specific forum.

Stand by
Good luck

Thank you

So I think my problem is resolved. I used Kies to update the firmware, which seemed to successfully return the phone to unrooted stock. I reactivated my network via the VM website. I can send and receive calls and texts. The only thing is that I don't see the VM logo screen at startup. Should I be worried?

If everything is working as it should then no worries about a missing splash screen... Sounds like you're good to go
