Galaxy S4 SIM Card Blocked

My Galaxy S4 randomly lost its signal a few days back, since then I have flashed it to Stock Rom, flashed to stock recovery and kernel, did a factory reset, wiped cache and dalvik cache, tried to unlock using the *#0011# method. Still sim card is regonised for a moment then it is blocked after a few seconds. Can anyone help please? Thanks.

Anyone knows how to fix problem??

Just be patient and give the guys here some time, remember that in some parts of the world is midnight right now. Now, I assume you have tried that same sim card in other phones to make sure the problem is not the sim card.
Cheers

Yes, tried that, do you think I should try flashing the modem again? Or maybe I messed something up in the phone service menu when I was unlocking, through the nv_backup menu?

Hello im new in here!
Im using samsung galaxy s5 g900f and it was working perfectly. But yesterday idiotic me entered an mmi code which is *35*0000# so all my incoming calls and sms' barred.
After that i tried its neutralizer to go back normal which is ##35*0000# but it didnt work. I tried dozens of mmi codes but it just stuck in there?!
Anyway after that i go back to default options menu on the phone. Call settings -> additional settings -> call barring -> bar all incoming calls. It asks for a password which is defaulty is 0000, it gives error and goes back. Tried to change password and it gave error too.

You could try flashing the stock rom with Odin and factory reset afterwards to see if that fixes the issue.

Thanks for the quick reply!
But i already flashed the rom and god knows how many factory resets. I almost deleted everything on the phone bu that barring option never left.
Im using xtrestolite v 1.2.1 at the moment.

Need help badly! s5 problem

Ok, newbie here so please be patient. I have a tmobile s5 with root and custom rom and simple unlock code. I've been using it for like 2 months with an occasional not registered on network. Well as of a week ago no network got worse, having to restart a lot until finally I get not registered on network all the time. When I go to network operators and search I get nothing. So I have wiped, factory reset, reinstall Phil recovery and new rom. Still nothing. Can anyone please help, thank you!

Do you have an IMEI number when you dial *#06# ?
If not, I hope you backed up your EFS partition

Need some help getting back into things, thanks!

Hey all! I have made the switch to a Nexus 6P about a year ago, so I am quite rusty with the S5 and how to do things with it. I recently sold an S5 on swappa, and I am attempting to help that user get it back to stock. I would have done this before selling, but we thought the process would have been more simple.
To quote the user I am assisting at the moment "... I crossed into canada a few days ago, phone worked good with international plan. cross back to US and keep getting weird "not registered on network" messages and have 0 connectivity to my Verizon phone network. Tried new sim card, verizon store says the issue is because it is rooted etc (doubt they know what they are talking about)....But figured i'd do a clean install etc and see what happens. Followed instructions for Odin. From what i read it sounds like I need the OA 8 Lollipop retail tar..phone model number is SM-G900V. Keep getting "NAND Write Start!! FAIL! (Auth)" in Odin. Tried multiple USB cables and other random tips I found online. Any advice? Am I using the wrong stock tar?"
What can I/we do to resolve this issue? I have searched xda, but I am totally lost with the S5 to be honest. Things have changed so much since I used the phone that I have no idea where to start. It was on Alliance ROM before I shipped it. It has the Toshiba eMMC (or whichever doesn't have bootloader unlock).
Again, thanks in advance guys!

Some more info about the phone, I'm the buyer.
Still running Alliance. I do have an IMEI # (some sites say that could be an issue).
Model/Phone name is Samsung Galaxy S5 SM-G900V
Baseband Version is G900VVRU2BOK3
Kernel Version: 3.4.0 [email protected] #1
Tue Nov 17 20:06:51 KST 2015
Build number: AllianceROM_VZW_V10_G900V_XXU1BOH4
Knox version 2.3
Exact message I get is "out of service area" when i make a call. then a "mobile network not available" message will pop up after.

Silly question, but have you tried pulling the battery, and Sim, let it sit for a sec, then power on to see if you have service? Might just need to reset the prl. Never been to Canada with the phone so idk what's going on ha.
Could also check the data settings to make sure it's set to CDMA+LTE instead of global or whatever other options it has. You haven't flashed a new radio file, have you? @miketon907

Pulled battery out and sim. No service fix. If I turn phone on with sim card out, it will say "no sim card". back sim card back in, no net work connection....It is set to CDMA+LTE. No, I have not flashed a radio file.

Ok, just trying to rule things out.
You activated the SIM in the US and used it before going to Canada, right?

Yep. so Sim card A which I got after buying the phone was working good. I went to Canada and used same sim card on international plan, went back to US and suddenly phone loses mobile connection and has no service as soon as I cross US border. went to Verizon for sim card B, sim card B does not work either.

You could try just doing a factory reset on recovery if you haven't already. Instead of starting from stock. Just wipe the data partition. If you wipe the system partition it won't have anything to boot into

oh. Well i'll try that later tonight. Report back around 11pm est. thanks!

Try flashing one of the modems on this page. It should reset the radio to have service again. I'd do it without the sim card in. Boot once, you obviously won't have service since there isn't a sim. Then turn off the device, insert the SIM and reboot.
I am looking into the write fail now just in case you can't even flash a modem file.
Also, you downloaded the samsung drivers, correct?
EDIT: I found an old thread that might help you troubleshoot odin - http://forums.androidcentral.com/sa...hacks/391849-galaxy-s5-odin-failing-root.html
EDIT 2: You might just have to switch to a different tar file. This user states that they used the same stock version as the one they were currently on. I'd give that a shot first. Then check to make sure "block reactivation" in security settings isn't checked. The exact directions that should get you going are from a user on that page, as follows;
"chainfire xda quote op-Follow these instructions to the letter. Do not touch any buttons or checkboxes that are not listed below to touch!
- Download and unzip the CF-Auto-Root-....zip file (see posts below this one)
- If you end up with a recovery.img and cache.img file, you've extracted twice. You need to end up with a .tar.md5 file - don't extract that one
- (USB) Disconnect your phone from your computer
- Start Odin3-vX.X.exe
- Click the PDA button, and select CF-Auto-Root-....tar.md5
- Put your phone in download mode (turn off phone, then hold VolDown+Home+Power to boot - if it asks you to press a button to continue, press the listed button, or run adb reboot download command)
- (USB) Connect the phone to your computer
- Make sure Repartition is NOT checked
- Click the Start button
- Wait for Android to boot
- Done (if it took you more than 30 seconds, you need practise!)
NOTE: Sometimes the device does *not* boot into recovery mode and root your device. Just do the entire procedure again if this happens. If it still will not install root and such, make sure that in Odin "Auto Reboot" is not checked. Then after flashing, pull the battery, and boot with VolUp+Home+Power button to boot into recovery manually. This will start the install process.
New to Samsung? Unfamiliar with Odin? Think all the above is a hassle? Get used to it. It's very simple, and us Samsung folk use Odin (or Mobile ODIN ) for everything! It's so very very convenient once you get used to it. Notice the 30 second comment above? For experienced users, the entire process indeed takes only 30 seconds!" - Dale Borrelli
Final note. Try the tar for the android version you are currently on first, then go up to the version you'd like to be on.
Edit: @miketon907 any luck yet?

yes, thanks a lot. flashing the modem worked. have service now again.
