I am trying to get back to unroot state on my galaxy s4 i9505. It is running fine and shows I have signal but will not make any connection when trying to connect to Vodafone UK. I am not tlk sure if I need to flash anything with the CSC?? The phone will just not register on Vodafone UK or any other network (it is an unlocked phone) I think j may have flashed the wrong firmware somewhere. I also bought in the UK but suggests otherwise?
Please help me to get back to getting signal and restoring the phone! Its driving me crazy! Please ask me anything else if have any questions. I have my imei number which I haven't shown which links to the label under the battery so that seems to be ok.
Thanks in advanced

1. Install Kies 3 and plug in ur phone.
2. Take a look the CSC in Kies 3 (pic 1 attached)
3. Go to Sammobile.com and download the correct firmware for ur device (knowing now ur correct CSC).
4. Unzip it and flash the firmware (.tar file) through ODIN.

I'm sure you thought of this but have you checked your APN Settings?
For Vodafone UK check this link: http://apn-settings.com/uk/vodafone-uk-apn-settings/

Yes I have checked APN settings, unfortunately still not working
I managed to find a csc by typing *#1234# see attached picture.
So, with the information I have found, would this be the correct firmware for my mobile? slovenia?

Seems to be correct, I may go ahead and flash it. Am i correct I just load into pip on odin and flash?

You don't need reflash it coz seems to be correct. Try first to:
1. Make a backup of your Internal Memory folders to ur pc.
2. Factory reset ur phone (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Tell me how it worked :fingers-crossed:

really appreciate you trying to help Joku, but I have tried factory resetting 3 times now, and still will not register on Vodafone UK What am I doing wrong!! Is it because I have flashed the Vodafone uk firmware instead of the Slovenia version which apparently is what my phone is? (I bought from amazon uk, I thought it would have been uk unlocked)

I hope these images help. Let me fill you in on what I have *tried* to do to help.
I have inserted a Vodafone UK contract sim. I have flashed Vodafone firmware and now changed the CSC code to VOD (Vodafone UK... I think) so I just thought my sim card would be working again.... Still shows signal bars but does not connect to network or wireless now... Can it be something to do with my modem???? Does anything stick out to anyone that is wrong???
Just to say my imei no and serial no are still intact I have not lost them or they have not gone to 0... They match to sticker behind battery. I just cannot work out what is wrong
Please help people! I appreciate it! [emoji4]

any help would be appreciated!! it's driving me crazy

please, i am still stuck with this phone!

D800 Can't Run Custom ROMS Please Help Me

I can't figure out why I can't get LTE or send text message on any custom ROM. Stock ROM (all versions) flashed trough LG Flash Tool and stock based ROMS through TWRP work fine. CM11, Cloudy, ect (I've flash a lot) all give me the came problem. No matter what AT&T APN I enter I only see GSM/WCDMA when I search networks (plus some T-Mobile), nothing with LTE. I CAN receive texts but not send (pictures or just straight text). I liked CLoudy G3 so much I flashed it more than a few times, deleted LTE APK file, re-lashed kk baseband, edited build.prop. Nothing I do fixes the issue. I just flashed back to stock with LGTool "C" firware and took the OTA "U" and will have to stay this way unless someone with a D800 can help me. I have flashed back and forth to stock /recovery many times and it's always the same.

Just to help troubleshoot and start at the beginning...do you have enable data checked and you're set to LTE (recommended)?

[Q] Help please! KLTE unlocked rooted on stock fw. Neither SIM can access network

Hi guys,
I think I was messing around where I shouldn't have been and now I have 2 SIMs from 2 different providers down on my unlocked rooted W8. I had moved it back to XtreStoLite successfully and then for some reason I started exploring service codes and I think thats where I killed it. I've completely formatted both drives and reinstalled factory but I'm still getting the same result. The Bell SIM just says Emergency Calls only and then you go into the networking area and it says Insert SIM for network services. The Koodo SIM gets a totally different result as its getting the PUK-locked.
Any wonderful ideas?
Thanks a million.
Tony

Estrongs and CSC folder attached in zip format
Does anyone have any ideas on this? I got the PUK-Unlocked taken care of on one SIM only to end up with the same problems on both SIMs. The SIMs still show as unlocked as per CSC but the status is LIMITED.
I think what I need to do is blow away the CSC so any remaining tainted records are gone.... somehow without breaking the unlock. I guess this doesn't get wiped even when I'm in PHILS and highlighting and formatting everything and then reinstalling factory firmware from SAMMOBILE. I've tried updating Bootloader, Modem and then firmwares several times. I've been to the shop that unlocked my phone and they say well if its not asking for a code its still unlocked. I've talked to the PUK detective at Koodo. I've been to the Bell store only to be sent out the door in a rude manner.
I think what I need to do is reset part of the service code that contains SIM stuff.
Any guru can help me PLEASE???
Below is more descriptive info with screenshots of the issue and my troubleshooting.
Thanks,
Tony

@AltaEgo
Not sure why did you attached the Estrongs folder?
Did you try to flash stock firmware? Are your IMEI and baseband still valid?
And please check the following:
open Dialer, enter *#0011#, Menu, Back item, Menu, Key Input, enter Q0 and OK, wait for some seconds until you get MAIN MENU. Then select DEBUG SCREEN > NAS INFORMATION > MM INFORMATION > capture this screenshot. And then Menu, Back item, MM REJECT CAUSE and also capture screenshot.
Can you show these 2 screenshots?

Hi vndnguyen,
My IMEI LOOKS ok and my baseband does too but I'm just look at the About Phone>Status .
I'm not sure why I put the estrongs folder in there. Sorry, I was up for many hours straight trying to fix this. I used your Samsung Info folder to try many different codes with no luck. In this situation, you get the no sim error when you try to put a service code in the dialer so its necessary to root the phone and launch them your app. It seeps for whatever reason that the SIM is deregistered and almost not seen at all. One SIM I can get a little bit further than the other. I have tried restoring two different firmwares from Sammobile and also one with Kies, but NO LUCK.
I really hope you can help. I'll be so grateful. Even the provider wasn't helpful.
Thanks very much for your assistance.
Tony

According to the screenshots, the problem was that the network consider your phone as a illegal device. The network refuses service either because an ID of your device is not acceptable, or because the device does not pass the authentication check.
So please check:
1- Put your SIM card into another phone to make sure it works fine?
2- Make sure your phone's IMEI is not blacklisted?

Thank you. This is very confusing as I got my S5 as new. I spent another 40 minutes with Bell on the phone tonight and they certainly didn't mention anything of the sort. I'll try these and then get back to you.
Thanks!
Tony

Well I've tried reinstalling stock and complying with Knox with no luck. I've tried completely blowing away everything to do with Knox after wiping EVERYTHING and reinstalling appropriate boatloads, kernel, modem.
I'm at Bell now. Gonna ask why the hell I've talked to 3 CRTs on the phone and in another store and Knox WASNT EVEN MENTIONED!

If your warrenty is void (knox tripped), you could risk it and try to add all bands to your phone. Maybe it could reset something?

I got the phone replaced through my smartphone insurance package. Luckily I don't have to pay the normal 150 deductible because my S5 was an insurance replacement and within its warranty. As far as the 0x1 causing warranty to be void, I highly doubt that crap will stand up in court. Because you install a custom recovery to BACKUP your phone for recovery, your warranty is void? That's a loud of sh*t! I think that all of us Samsung customers should put together a petition letter expressing our displeasure with Knox. I mean, it doesn't really do anything for us unless you're with a corporation or you pay for one of the upgraded copies. I can't even figure out how to login to Knox on my insurance replacement but it's there and running.... well it was. lol
I'd really like to find out what happened to this phone before I send it back. I think I might try adding the bands.
Anyone else have any ideas as how to reset the Qualcomms through the service menu. I suspect that this is totally separate from Android and that in here is where I messed something up that tripped up the modem settings so it won't read SIM cards. I want to reset the Qualcomm back to factory defaults.

Warning - You cannot sim network unlock the XT1524 with an unlocked bootloader/CM13

Hi guys, just a word of warning....
I flashed my stock en-GB android 5.0.2 xt1524 phone with en-EU 6.0 rom then flashed with CM13. I was unable to unlock the network sim-card lock that would allow me to use sim cards from any network. In order to relock the bootloader you need an official rom installed, i tried flashing with the en-GB 5.0.2 rom but i got these errors:
{

"lightbox_next": "Next",
"lightbox_previous": "Previous",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The problem seemed to be that i had previously upgraded to the en-EU 6.0 rom which upgrades the bootloader so i had to re-flash the en-EU 6.0 rom.
I then re-locked the bootloader and booted the phone up and put in my network unlock code that i bought for £2.50 off ebay and it successfully unlocked
PLEASE NOTE: I'm not sure whether the bootloader has to be locked, root to be removed or whether you just need an official rom and not a CM13 rom for this to work. In hindsight i should have tried unlocking my phone straight after flashing with en-EU 6.0 without re-locking the bootloader then i would know whether it was having CM13/root that was at fault or having an unlocked bootloader.
P.S I tried entering the network unlock code at least 6 times and it didn't lock me out of the phone or stop me from unlocking it successfully later on so don't stress yourself out over retrying the code fearing that it will lock your sim card forever, that won't happen, not for the first 6 attempts at least.
p.s the reason i didn't unlock the network lock when i first got my phone with stock android 5.0.2 is that many ebay unlock code sellers too ages to respond and those that did were unable to get an unlock code for my phone. I eventually found someone who could get a working unlock code for me.
Here is the errors that i got when trying to re-lock the bootloader when my phone had CM13 on it:

Content of EFS folder I9505 - please check (there is folder content, but IMEI null)

My phone says IMEI unknown, baseband unknown. I don't know if anything is missing from my EFS, but it is present on the phone memory in root folder. Can someone with I9505 please check the files in EFS?
I returned stock firm, but still no imei, so no network.
Here is my EFS folder:

}
Here is my menu (Cyanogenmod):

Ive got bluetooth, carrier, cpk, drm, factoryapp and log folders in efs..no lost and found, never installed cm, you probably need to flash the modem/bootloader

Are you with I9505 exactly?
I tried flashing modem several times :/
Can baseband: unknown be a hardware issue?

yea the i9505, what firmware and modem version are you flashing??

First it was stock 5.0.1 XEO touchwiz. Working normal 1 year, then it started loosing network coverage.
After that, i flashed CyanogenMod 13. The coverage problem continued. Then I flashed AOSP 6.0 - same thing. But I had EMEI and baseband OK.
After that I decided to turn back to stock. And some time after that it lost IMEI and baseband. It could be the hardware problem got deeper, I don't know. Since then I tried almost everything. The EFS folder is on the device. I've changed permissions, made efs backup, restored it - no IMEI and baseband. Installed xposed and IMEI changer - set it to my original IMEI. There was IMEI, but again no baseband! I tried getting back to 6.0.1, because the IMEI/baseband was gone when back to 5.0.1. But no IMEI/baseband again.
So I'm stuck.

The IMEI no longer lives in the EFS partition, but in hidden partitions on the device that you cannot normally touch. Thus touching the EFS partition won't help you restore the IMEI, as there is no NV Data in the EFS partition and hasn't been for some time now. So if you're missing your IMEI and didn't make a backup of those partitions using the Wanam Partition Backup tool, you'll have to have the phone serviced. The items that we can flash using Odin do not include those hidden partitions.

Thank you, man! I was so desperately searching for nv_data.
I actually have a back-up, but it was made with clockworkmod, but maybe it doesn't include those partitions
Actually the modem partition maybe is my biggest problem, cause i wrote down an IMEI with xposed, but no baseband, so no need of imei

Nandroid backups don't touch the hidden partitions, so you won't have any of that data. Writing the IMEI I'm not sure is going to help you much, especially where you have already attempted to restore the stock radios on the device.

When i read the info with a tool, PDA, CSC, Phone S/N are present.
The following are empty:
HW version:
Modem board:
RF cal date:
IMEI:
Any ideas?

Modem Board and Hardware Revision having no information is normal. I can't answer about the RF cal date (RF Calibration date). However, not having an IMEI is not normal. Since your NV Data was somehow wiped out in the hidden partitions, your IMEI was also wiped out. It doesn't matter what stock ROM you install, you will not get your IMEI back because there's nothing in the hidden partitions to be read. Therefore your only alternative is to take the phone to a service center and have them restore the IMEI.
