[Q] HELP! Data but no signal!

So I started today feeling a little creative so I flashed the newest MIUI ROM, there was a data issue that I tried to work out and in the end screwed everything up.
I lost signal but I have data.
I have tried probably 10 ROMs and the same has happened, I am getting a roaming sign, but it shows I have bars (I am connected to a wireless repeater so full service all the time on 3g).
What in the world do I do? I've seriously tried everything. I flashed back to stock through ODIN and nothing still.
PLEASE tell me someone has seen heard this problem... WHAT DO I DO?
Thanks in advance...

Go to settings - about phone - status and tell us if your IMEI is a bunch of zeros or a string of numbers.

It's not I its still the right one, that was something I checked... I considered doing a IMEI restore anyway and maybe that would fix the problem but I still definitely have it there. Thanks

How I Fixed It
Hey there. Not sure if your still having this problem, but I ran into the same issue with my new phone after rooting, unlocking bootloader, and flashing MIUI. To fix it, I had to odin to stock (Pre-Jellybean for the Samsung Utility), which I got from here: http://hotfile.com/dl/169363562/8975152/SCH-I535_VZW_I535VRALG1_I535VZWALG1.zip.html%20
Then I ran the Samsung Repair Utility from here: http://forum.xda-developers.com/showthread.php?t=1867442&page=18
The Samsung Repair Utility said my ERI was present and my IMEI was accurate per the back of my phone. Desperate, I ran the "Repair ERI" anyway which made no difference until I followed the OP's directions to dial the code to run the factory reset if the tool didn't work. That seemed to do the trick :victory:
Good Luck.

4.3 and ERI

So tell me how screwed I am.
I had CM10.2 on my phone, then my IMEI changed to "0", and I couldn't receive calls. So I flashed my phone to 4.3.
Next right before I fixed the IMEI issue the ERI changed to "none", and put me in roaming mode.
Well I fixed the IMEI issue, but I am now stuck trying to fix the ERI, it still says roaming and does not pull an IP Address.
Is the ERI possible to be fixed now that I am stuck in 4.3?
I tried RevSkills it says, "subsys efs is locked", then I tried Samsung MEID Repair (but it locks up, I believe because I am using 4.3)
Any help appreciated! I will be heading to the Verizon store here in a few, but I'm sure they are going to say buy a new phone or something.

Well Verizon store was not helpful, they tried a bit and gave up. But reading more, I am starting to think I can revert back to older firmware because I did not OTA.
Does this sound right?
Because several times, with 4.3, I tried using ODIN to go to ICS, Well ODIN failed each time with a SW REV CHECK FAIL : Fused 1 > Binary 0...
[Quoting toeshot from another thread.]
The problem is that once you install the 4.3 update you cannot use Odin to flash a downgrade ROM even an official Samsung ROM. You will need to install a custom recovery then flash a rooted rom,

I'm going to keep trying things, because basically this phone is useless right now anyways..if I hardbrick it oh well, it was good while it lasted.

Still working on this...
So where I currently am, installed safestrap and flashed over TW Wicked Sensations. Still couldn't access the "subsys efs" because its using the ML1 modem...
Well I flashed over the modem G1, didn't work, tried G7 also doesn't work because they just take it to the "System software not authorized" screen where I am forced to reboot.
I really don't know now. unless there is a TW somewhere out there that lets me switch modems without it bringing up the "System software not authorized" I am stuck forever roaming.
Thanks Odin for letting me flash 4.3 onto my phone without warning me I could never go back. :good:

Even flashing the stock 4.3 odin file locks it... There is an odin file with the MF1 BOOT CHAIN so it won't lock it, but its too late. Plug it into the PC and run the install helper to reload the totally stock 4.3, then call verizon and tell them that since the OTA came, your phone is always in roam mode. They should replace it.

I am in a very similiar boat. I was running 10.1.3 and did the upgrade to 10.2 and my IMEI reset to all zeros. So my question is how did you fix your IMEI issue? I flashed a working backup I took before I upgraded and that did not help. Tried other roms, etc and nothing

Yea the problem is the IMEI and ERI both exist in the EFS, so that is what you would have had to backup..It can still be fixed though. Couple of links for you here:
Youtube1
Youtube2
Software Required/Procedure
So this is the part I screwed up with after finding those links, I immediately flashed to 4.3 to fix the issue, don't do that. Flash it to like ICS ( anything lower than 4.3 ) and then do the procedure part.
Also you can find your IMEI on the sticker under the battery.

After exhausting all possibilities this seems like what I will have to do, its kind of disappointing because my phone is in excellent condition, I may just sell it on ebay for parts or something.
But can you riddle me this batman, even though its says I am roaming, I'm not right? So can I just use my phone like normal?

I have watched these videos but the part that keeps hanging me up are the commands that they have you dial. I put them in and nothing happens. If I hit dial it goes nowhere.

Same thing was happening to me...when I was in CM10.2. I would try the first command to enable Diagnostic Mode / Qualcomm USB Settings. and it would do nothing. I am fairly sure you have to be on a stock ROM for this to work. Also when you dial the commands, after you hit the last number it will perform the operation, you never have to actually press dial.
I saw people posting a bunch of different numbers to try that would bring up the Qualcomm Settings. But I can't really tell you which one you need because I'm on 4.3 and its a different number. But on 4.3 its called ( Enable DM Mode ). Good Luck! :good:

I was able to flash a stock room, use *#0808# gain access to the menu, etc and got my IMEI restored. I have data but am still unable to make/receive calls. Two things I noticed that might be the issue. The IMEI SV is 00 and when I go to Access Point Names that list is blank. I did reset to default but that did not repopulate them.

My IMEI SV is also "00".. but I can still make/receive calls. It sounds like you may have set your IMEI wrong. But I'm not sure, couldn't really help you past this, because I am no expert, like some of the people on here.

What do you show in your APN settings? I noticed at one point before I had my IMEI restored I had a bunch of different choices there... now it is blank.

Only have one APN, says "LTE - Verizon Internet"

I cannot seem to get my APN to save. I have entered it manually to match my wife's S3 but it will not save it. Going to Odin back to stock I guess.

well, i am kind of sad that there isn't a fix for the eri missing. Eff you verizon and samsung for making stuff we enjoy difficult!!

No Data/Calls on Viper 1.5

I have the weirdest issue, I searched around and have found no topics on so here it goes. Every time I try to install Viper 1.5 on the Verizon m8, Everything tells me it worked, then as I'm setting up the phone I don't have any Carrier calling/data. After setup is complete I still don't have any Carrier calling/data. Occasionally a message box appears saying sim is prepared and then I click on my carrier (Verizon) and the screen goes blank and repeats. Everything else on the rom works great! But I can't get my carrier data/calls! I've redownloaded, wiped, and re installed over and over! Hope I can get some help!
Thanks for the hard work and support!

Try reflashing TRWP newest version. I had the same issue too and this fixed it for me.

[Q] No signal anymore

Hey guys... I recently encountered a problem with my nexus 5. Suddenly my phone lost signal and it won't receive any more signal.I was on the latest version of PA on 4.4.2 ...... Now I factory reset my phone and it's stuck on phone setup... What do I do?? I'll try flashing back to stock later and I'll see if it's fixed... Also, before factory resetting my phone, I checked my IMEI and it isnt gone.... It was still there.. Strange... Any suggestions on what I should do? Also, I don't have a nandroid backup....

Still no luck
Guys... Returning to stock didn't do anything... Still the same problem... Now I'm stuck in setting up the phone since it shows that my sim is inserted and it's trying to activate the sim... But it stays there forever ... I'm pretty sure it's a problem with the sim holder... When I tried removing the SIM card for the phone, it failed to eject my SIM card... Now I have to find a way to get my sim out... When I use the pin, it only opens 1/8.. It's too small to fit anything in it... What do I do?? Running out of ideas...
I could give my phone for repair but I live in Dubai and I don't think there are any service centers here...

Oneplus one acting weird

My opo fell in water so its screen was not working. My father gave it to a mobile repair shop who repaired it for 4k. When he checked the phone everything seemed alright.He was able to call me etc etc. Then he couriered me the phone. When I got It... It had cos13 latest version. I checked everything except calling. Then I rooted my phone. Flashed oreo. I inserted my sim. It was able to detect that it was an idea sim and import contacts from it but it showed no service. I thought it was the rom. I flashed Tugapower N49. Same problem. So I thought restoring it to stock might solve the problem. Used oneplus one recovery tool to restore it to 4.4 . Still the same problem. It can detect the sim but can not catch any signal. I check my Imei number. Its still there. But I was not able to run the ping test. Then I thought of using this phone for checking roms only and use my Lumia(I hate Lumia) for calling. Rooted it again. Flashed oreo. Flashed its gapps. It show installation complete but its stuck there...... Waited for half an hour. Forced restart. oreo opened but It was nt factory reset although I had wiped it and it shut down after some time. after that my phone reached the android screen only and cant proceed further. I thought maybe force closing my phone during gapps installation did this. Tried to install tuga power.. error executing update binary. Had one more nougat rom. Installed it. Again it didn't show that starting google screen which u see when ever u open a new phone. Basically It was again not factory reset, Wiped everything except system. still this happened. Returned back to stock using recovery tool. Now I tried to install multirom so that I can install the oreo rom. after rooting multirom wasn't able to download anything. Downloaded it manualy. Flashed multirom twrp using fastboot. opened recovery . Not working. phone rebooting. Flashed the previous recovery which I was using before multirom one, That one is working properly!!! What is wrong with my phone???!!!!!
