[Q] S4 Sim unlock UK o2 network

I have read about the *#0011# trick
it doesnt work for me. I have read that you have to downgrade the modem, do the unlock and then upgrade it again.
So i have looked at my firmware at it is
Current firmware version : PDA:MEA / PHONE:MEA / CSC:ME3 (O2U)
i am rooted and have custom recovery installed, i am using touchwiz rom with quite a few customised bits in it using nova launcher too.
Kies it saying there is an update, but im not doing that just yet
to
Latest firmware version : PDA:MF8 / PHONE:MF8 / CSC:MG1 (O2U)
So i ahve look at this thread
( http://forum.xda-developers.com/showthread.php?t=2192025 ) with all the differnt modems.
and it says i have to downgrade to an older version but i cant see an older version that what i have.
Samsung say this is the newer version
GT-I9505 Galaxy S 4 LTE
PDA: I9505XXUBMF8
CSC: I9505O2UBMG1
MODEM: I9505XXUBMF8
Added: 2013-08-22
Can anyone / will anyone be willing to guide me through how to downgrade to an older modem, unlock and then i guess update to the newer modem? or back to the one i have now? and keep the uinlock?
I thank anyone who can help me.

can you help me find the correct one? for o2 UK s4 LTE.
and then once that is done, should i update to the newest one, which is the one above the one i am on now?
as o2 UK are switching on 4G LTE in 2 days time, i assume the new modem will allow for that?
Can that be done and not update the rom or will that be an issue?

Hi,
Go to the thread you mentioned,and in the i9505 section,look for XXUAME2
The installation instructions are there as well.
Then, yes, install the latest.
All modems work with 4g

Hi,
All that for nothing.
At least your learned how to change a modem.
Glad it all worked out for you.

Still having issues with my O2UK S4 i9505.
It was on ROM XXUBMF8 / Modem XXUBMF8 and couldn't get to the UMTS menu.
Changed to modem XXUAME2 and also tried the older XXUAMDC, both allowed me into the service mode.
In [NETWORK LOCK] menu clicking on [[1] PERSO SHA256 Info] says returns
SHA256_ENABLE_FLAG[1]
going back and clicking on [[3]PERSO SHA256 OFF] also returns
SHA256_ENABLE_FLAG[1]
going back and selecting [[3]PERSO SHA256 OFF] a second time returns
SHA256_ENABLE_FLAG[0]
SHA256_Off => Not Change
Has anyone an idea why I have to do it twice to get SHA256_ENABLE_FLAG[0]?
Going to [NV RESTORE] at this point reboots as expected, but still have network lock afterwards.
I've also tried this with native O2UK sim inserted, and with another non-O2UK sim.
I'm close to spending money on a code at this point!

[Q] No LTE option in Mobile Network

Hi guys,
I am sorry if this has already been asked and already been solved.
I have a Samsung galaxy Note 3, it is the N9005 version I bought it from someone here in the UK he got it as an upgrade on his contract from Mobilephonesdirect.co.uk
I am on Three network and I am on 4.4.2, I live in london.
I am supposed to have 4G however I cannot see the LTE option in Mobile networks, all I have is: WCDMA/GSM (Auto connect) , WCDMA only and GSM only.
my CSC is : N9005OXXENB1 , AP N9005XXUENB4 and CP N9005XXUENB1
I have rooted my device as i heard that might help? but havent changed any settings?
I am kind of a noob in all of this ?
would really appreciate your help ..
thanks

It does not matter. First at all you have to see it in options and set it on. Second is if your provider enabled it to use. Make sure that you have USIM instead regular SIM card fitted to proper size.

I Had The Same.Do This:
using root explorer go to:
system/data/property
using its text editor open the file:
persist.radio.lteon
change from false to true
REBOOT
IT COMES UP AFTER 3 REBOOTS FOR ME
Sorry For The Quote

This is something I deal with about 18 times a day these days... The joys of a provider launching LTE...
What happens is that each csc version has its own file with in it a list of all providercodes followed by a 1 or 0. If set to 0, the LTE option doesn't appear in the interface.
The sneaky buggers disabled the dialer code for manually enabling network mode on the Note 3. So ODIN is the best option.
What you have there is XEF, France. Since Three doesn't appear to use branded firmware, you need to flash BTU over it. (this wont trigger knox if you use the official firmware)

First of all are you on 4g network? If you are rooted, try editing this file /data/property/persist.radio.lteon file, set the content to "true"
good luck

GT-I9505 4g LTE option missing

If you dial *#*#4636#*#* do you get the testing menu? If so, go into Phone Information and check you are set to LTE/GSM auto or similar.

If you input that code in the dialer (correctly) it should take you to a screen called "Testing". If it doesn't then there is something wrong with your phone. This works on pretty much all phones.

@GDReaper: The Galaxy S4 does not recognize that particular version of the USSD code. It can be run however through the Phone Info app.
@khsh97: Please post the following information:
1. Model Number
2. Android Version, found by going to Settings > More > About device.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing Phone Info from the Play Store and running it.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)
Before using GDReaper's suggested method, post the information requested, so that we can eliminate other possibilities for why you don't have a LTE option.

I ran the code before posting and it worked on my S4. However, am running the gpe rom. Maybe that's why it actually worked

That is probable, as I'm running a rooted and debloated Touchwiz and it didn't work. But as mentioned, the Phone Info app is another way to get there.

Sorry for late reply!
Model No: GT-I9505
Android version: 4.4.2
Firmware: I9505XXUGNE8(official stock)
AP: I9505XXUGNE8
CP: I9505VFGGNE8
CSC: I9505VFGGNE2
My phone is rooted with towelroot however the option was missing before root as well.
BTW, I don't have LTE sim, does that matter?
If that matter then how can I check without LTE sim?
And yeah, the code *#*#4636#*#* is not working in my galaxy s4.
I am going to check out phone info app.

If you don't have a LTE SIM, you won't have LTE as an option. Upgrade your SIM to a LTE version and you should then be able to select LTE.

Ok, thank you...!!!
By the way, why the code is not working on official touchwiz roms?

Ask Samsung that question, but don't expect an answer. There could be a multitude of reasons why Samsung disabled it, but unless they pony up a response we'll never know.

Lol, Nice answer!!! Anyway phone info app can do it so why we should argue with samsung for disabling that code.

I think you must have firmware based on your country to have LTE. Now I'm downloading 4.4.2 for my country and I'll keep you posted

@velizarcho123: And you'd be wrong. LTE depends on two things: having a LTE-compatible SIM and having the proper frequencies in the radio chip to pick up LTE service. Assuming the device is neither region nor SIM locked, the moment you put in a LTE SIM Android will load the APN for the carrier into Settings. LTE should then work immediately. If it doesn't, the APN can be modified in most devices so it does work.
That said, if possible, using the firmware from your home region is the smartest idea, as Samsung does modify the firmware a bit, usually by removing languages other than those spoken in the region.

All firmwares have LTE, I does a trick - rooted my phone and modified a system file that enables LTE in the network menu. This is stupid Samsung restriction.

Reread my post. You were able to modify the firmware, but that modification would not have worked if the SIM wasn't capable of LTE and the radio chip didn't support the frequencies used.
EDIT: Just to clarify, Samsung modifying firmware to remove the option to use LTE does not mean the firmware doesn't support LTE. Clearly it has to support LTE if your modification worked. This means that firmware is eliminated as a variable, leaving the two remaining variables as the SIM and the radio chip.

1. Install Kies 3 and conect your phone to the pc.
2. Take a look your CSC (pic attached)
3. Go to Sammobile.com and download the correct firmware (with correct CSC) for your device.
4. Flash this firmware through ODIN.
5. Enjoy :highfive:

Hello Joku1981 !!
Thanks for the reply ... My device belongs to the UAE region and I am in a different one and the device don't have a firmware for the region i am in ... but I got it working through "Service Mode" *#0011# ... I changed the preferred network mode to GWL ... Though doing this doesn't make the option to be visible in More Networks --> Network Mode .. but I am getting the 4G/LTE reception on my device ...
Hey you or anyone else have any idea on how to make the LTE/WCDMA/GSM option visible in the Network Mode ... That will be awesome ... Thanks.
You guys rock ..

The final and correct firmware for you is this: ONE. This will give u LTE/WCDMA/GSM option visible in the Network Mode. Flash this firmware 2 times if you have problems with wifi or sound. Tell me how it works. Good luck

This is probably going to fix it, but just to mention that I was on the correct CSC and I still had to do a factory reset for LTE to become available (go figure).

Signal unstable one bar or no coverage

Hi guys,
It's been a while since I've been having weak or no signal (one bar or maximum two everywhere all the time), the funny thing is showing the coverage bars even when there's no sim !
Below are attachments of informations for device. Thanks in advance.

The firmware that you are using is a leak and the baseband is of android 4.4.2. It's normal that your phone is a lil bit crazy. Install this APP and add some screenshots for avoid problems and I will tell ya what firmware you have to flash via ODIN.

A device always shows coverage bars without a SIM. It's the Emergency Network. 112, 999, 911 or whatever your local equivalent is, you don't need a SIM to call the Emergency number.

Switch to GSM only mode. Sometimes in areas where coverage is weak LTE/Automatic mode doesn't work well.

Your IMEI is your phone's equivalent of a social security number, NEVER share it with the public.

You will have to flash one android Lollipop Firmware coz your bootloader is updated. Your CSC (country code) is BTU (UK) but doesn't have android 5.0 still. I recommend you flash this firmware for example via ODIN. Good luck and tell me how it worked for ya. Remember dial *#1234# when the flashing process finish and have to appear:
AP: N9005XXUGBOB6

Reflash the firmware if not.
