i9505 no signal connection or 3g/ 4g """"""SOLUTION FOUND TO ALL USERS!!!!!""""""

SOLUTION:
THIS IS FOR ALL WITH NO CONNECTION OR CONNECTION ISSUES, DUE TO UNLOCK OR NOT


before you begin, if your phone is not factory unlocked, you will lose your aftermarket unlock

donwload the rar file

extract content, install all


on the phone:
Type *#9090# Select option 2 (DM/DUN over HSIC)
and
Type *#7284# it will open a new menu or If *#7284# does nothing type
*#0808#
. In this new menu:
- Set USB to AP
- Set USB settings to DM+Modem+ADB

login to server for free... user : test pass: 123unlock

click advanced, read nvm to do backup, now select write, search for i9505 repair file, and proceed

after 3 min phone will reboot, you will not have network connection!

INSTALL your firmware from sammobile, let it finish... let the phone power on, and when reboot is complete, power off, enter recovery mode and format your phone to factory specs (down volume+home button+power on)


your done, enjoy!

So in my country all service providers work with 3g at 2100 frequency, why does my s4 doesn't connect to 3g?


Well... sadly after digging around i found out that the phone doesn't support 2100 frequency.

It's the official firmware for this country, was bought in this country but only gets 2g and 4g

any way to solve this mess? most of the data signal comes from 3g signal, if i'm inside of a building i only have gsm data :crying:
Dial *#1234# and tell me what appears :)

so.... I9505XXUGNJ8/


csc I9505YXXGNK1

i flashed a new firware from sammobile
so... as i search for 3g, only show vodafone, not the network that i need, the phone is locked to NOS. Also should show MEO 3g, and doesn't.


Strephon Alkhalikoi impossible to make that mistake, inside any building with another s4 i get 3g fine :(

Inside the buildings there is no 4g cover, i really need the 3g

Based upon the information you've provided, you're on the Baltic Black Edition firmware (CSC SEB). The firmware here though doesn't appear to be the problem. The problem is that you need to clear up some confusion here. You're saying you can't get LTE, are using unbranded firmware, yet your phone is locked to a carrier.

In an attempt to clear up things, please provide us with the missing information below, and confirm any already provided information is correct.

1. Model Number
Answer: GT-I9505, based upon the title of the thread.
2. Android Version, found by going to Settings > More > About device.
Answer: 4.4.2, based upon the firmware information.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing and running Phone Info from the Play Store.
Answer: AP and CP I9505XXUGNJ8, CSC I9505YXXGNK1, which using the sammobile.com firmware checker links to the Baltic Black Edition firmware.
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)
Answer: No, if you're able to pull up the firmware version via *#1234#.

@Joku1981: If I didn't have to work today I would have told him the same thing.
@monteiro-ribas: If you intend on having the phone swapped out, you might want to flash the correct firmware that Joku1981 provided the link to before sending the phone in. I do hope you let us know if you get your issue resolved and whether it actually was the phone or, alternatively, the service.

@pzyfocker: Post your information in this thread, rather than the Modem thread. It will be easier to follow.

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

6. Is the phone rooted? (Yes/No)

My original post in modems:
Ok guys, my kingdom for a solution, please !!!

Here's the deal, I have a samsung galaxy S4 GT-I9505 bought in hong kong, worked flawlessly for over a year on Telcel Mexico network, took a trip overseas to France bought a sim put it in the phone, worked great !!!!, came home put in my original sim and since then my S4 has been unable to maintain a stable 3g connection, usually connects for a under a minute and reverts back to edge. I've tried many different things recommended on this and other forums:

1.- removing/replacing sim card
2.- removing/replacing battery for over 4 hrs
3.- tried different sim cards from different carriers with same result
4.- wipe and clean install with different firmwares
5.- installed cyanogenmod latest
6.- under network modes, tried selecting every combination of lte, 3g, 2g, automatic network registration and selecting my preferred network.
7.- tried flashing over 30 different modems
8.- flashed latest firmware from sammobile specific to my phone (I9505ZHUFNL1_I9505ZZHFNL1_TGY)
9.- took it to a "technician" and he managed to return my phone in the exact same condition with the exception that now the wifi didnt work (i managed to fix this on my own)
10.- installed advanced signal status from play store which gave acces to other goodies such as selecting radio band between automatic, europe and usa, tried everyone of them with no solution.

Tried to be as thorough as possible, hope someone out there has a solution. I thank you all for your time and experience. Happy Holidays !!!!! I hope I am posting in the correct area, i searched and found this is the place where my problem seems to be discussed

P.D. Since im flashing GPE right now the screenshots no longer reflect what im on but I do have a nandroid back up of this rom and I am about to restore it.

Hope I was thorough, thanks for any help

Downloaded SRS tool from another link which finally gave me access to Samsung Remote Unlock Client, followed the steps in the guide, used the file provided in this guide and everything seems to be working for now, gonna test for a couple of days and will update.

I have attached the files I successfully used. Great many thanks to the OP and to the 123unlock team, had this problem for over a month and fingers crossed this appears to have solved it. THANKS
