hi i know there are a lot of threats already of this but now i bring a posible solution to this problem
in my case is no hardware problem cuz i change it, i have falshed a lot of modem and still says no sim... insert sim
btw the phone is unlock. so i decide to leave my skyrocket as nonfuntional phone but i start tu play with the service mode
and suddendly recognize the sim card and get data and works great. but it only works until you reset or power of the phone.
if that happend you have to do my steps again and that way you get sim recognition again.
i post this cuz im not a developer i dont know to much about debuging mode so plp that know that can see my steps a find a permanent solution
to the no sim error on skyrocket.
before start you have to inserte the FUNCTIONAL SIM CARD and power up the phone, it will power with no sim error
un dialer put *#197328640#
enter to debug screen 1
enter to phone control 8
enter to simulation 5
enter to modem Assert (reset)
at this point it appear to dont do anything but wait like 30 seg you will see the signals would restart and then do this
press menu and choose end
there it is now it recognize the sim...... so it possible is something with MODEM ASSERT (reset) but this is a solution not PERMANENT cuz when you reset o turn off the phone you have to do this again to get sim recognition again
so pliz devoleper make a PERMANENT solution with what i found
i try this with an att skyrocket with UCL2 baseband and UCL2 oem root ics
if you guys try this or think it its not possible just post me and on the weekend i ll upload a youtube video with all the steps and you ll see that it works

well the defective skyrocket showns the imei and mac and its correct with the back label, i already backed up tha efs folder. i also try tu run the GSII_repair ant it says on step 3 nv_data.bak and his nv_data.bak.m5d is miss so i think that the problem is something with that. As i have the back up of my partial efs folder i think i can start playing around and see what i got cuz in my partial efs folder i have my imei backed up
what do you think?

leave the efs folder alone, just try the stock firmware as is to test
I too am having a problem with an AT&T Skyrocket that is rooted. I have been using it without a problem with Straighttalk's AT&T SIM. I decided to switch it to T-Mobile's $30 plan and unlocked the phone. It worked except service was extremely poor so I flashed the SKY ICE 4.2E R5goo.zip and SKY ICE 4.2-17.zip ROM (T-mobile radio). This didn't work any better so I read that I should try a couple different radios. I attempted to flash the Blaze radio since that seems to be the most popular and after rebooting I get the no SIM error. I have reflashed the stock ROM using ODIN (several times) and now neither the T-mobile or ST SIM is recognized.
I found this thread and attempted to go through the procedure but there is no modem assert reset on my menus.
Any help would be a appreciated.

Did you notice in odin if it flashed files named mdm.bin and amss.bin? That's the radio.
In case you didn't (and didn't read the 1 stop thread), here are som links for radios:
A thread with only t-mobile radios (work on our phone too) and here are all the i727 radios.
Hopefully this will help, but really i'm just guessing, maybe someone else can spread some light on your problem.
I'm guessing (hoping) that for some reason the blaze radio failed to flash and so you got a corrupt radio. Then you flashed stock tar that didn't have modem in it.

Yes it did flash the mdm and amss bins. I'm suspecting something happened to the SIM holder since it will not read any of the SIMs (Tmobile, ATT or ST) I tried in it and have another on it's way. I'll see if that changes the outcome.

hello everybody i hope u can help me
i have s4 i9505 it gives me no service
the imei is in it its not null
and its has android 4.4.2
i tried *#0011# it didnt give me the menu
and i tried *#*#4636#*#* didnt work
please help me
Is the sim card detected? Is the sim card good? Does the phone detect any carrier networks? When did this happen? Did the phone ever work properly?
yes it c sim card cuz it shown the sim application for the network
the sim card is good and also i tried 3 sim cards for 3 networks
it happen from many days after i change the sim card in it
everything else in the phone works good
All I can suggest is reflashing a stock firmware from sammobile.com and then try again.
i did that
and i will do that again now
but i think is the radio is off
and i hope to find away to make the radio on
same problem
Are you flashing the latest rom for your phone? I though 5.0 was the most recent release the 9505.
same problem nothing happen
still no service and mobile network not available
This happened before to my friend's i9505 all of sudden . Long story short .. in his case it turned to be a hardware defect .
Check baseband version in settings >more>about . If it is there then you r good to go on software thing . If it shows "UNKNOWN" then unfortunately your modem IC chip is broken (hardware failure) and there is no solution here @xda to repair it . you'll need to bring it to service centre.
Good luck

So you flashed a stock 5.0 rom? Are you able to try a custom rom to see if that makes a difference?
This is not a big issue.
all you have to do is to flash another modem.
Hello , i'm new here
unfortunately i have a problem with my S3 verizon SCH-i535 , when it was stock , i couldn't add an APN , i just could make calls and send sms, but no 3g connection.
i thought if i flash a new rom i could fix it , so i tried to flash CM12.1 ROM for Galaxy S3 Verizon SCH-i535 as shown on this video :
youtube.com/watch?v=4xu1Vgink8Y
but it made it worse , now the phone doesn't even detect the sim card , and there isn't even an option on the setting menu to access APN.
Please help me guys ! if you need more info just tell me.
I fixed this by putting my sim back to the phone and reflashing , everything works fine now.
however , when i call sombody and and cancel the call its keeps on calling , how do i fix this ? or do you have any stable good rom to flash it ?

Check under status, does it show your IMEI or does it say unknown
