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

Hi, thx for this, need a little help, im on stock rom, used the dial pad, set ap to your specs, I open the program in the zip file and cant find an advanced button, and hence cant continue, do i need to root the phone with this app and then an advanced button will appear ????

So far so good

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

Few problems with a Samsung Galaxy S4

Hello! It's the first time I write on this forum. My problem is: my phone came with Android 4.4.2 and I decided to pass on android 5.x. All well and good until it started making trouble in the sense that when I call someone, sometimes the caller does not hear me and vice versa, volume goes minimal alone. What do you advise me to do? The cause is related to software or hardware? I must go back to 4.4.2? Thank you!

How to Fix 3G WCDMA Only Signal Drop Problem in GT-I9505

I have a Samsung Galaxy S4 GT-I9505 Made in Vietnam. I live in Bangladesh. It was shipped to here (may be from Saudi Arab. Not Sure) in December of 2014.

When I inserted sim and turned the phone on it asked for SIM Unlock code. We did not have any code. So, it was sent to a repairing shop and following night I got my phone working perfectly.

In February 2015, I was digging with many custom roms and once installed CM Lolipop ROM. Suddenly at noon, I noticed that my phone has no network signal. I overlooked and when I checked my mobile back at night I saw the same problem. Then I switched several sim cards that I won.

Then I noticed only 2G or GSM mode was working. If I selected WCDMA Only, the phone lost signal and it was showing a circle shaped sign on the network bars indicating a big no.. If I selected 2G, I was able to get 2G network but no 3G.

Here in Bangladesh, no 4G or LTE network available. So 3G is the only hope for getting a faster data connection. So I searched all over the Internet for solution but couldn't able to find the right path. Moreover I made some softbrick to my phone several times. And I gave up trying. Then, I used WIFI and 2G on outside of home.

In late of November 2015, I sent the phone to a repair shop. After digging many times He fixed my phone for 4000 BDT or 51 USD. But unfortunately it was behaving like previous from that day. I could not use 3G. The same problem started again. As I have wasted my 51 USD, I did not try for once again to go to repair that (I also did not get enough time).

Now I am still using with WIFI and 2G only. I found your tutorial but your TUTORIAL didn't help me.

Currently I am using Official Android Lolipop ROM of XME country code (Downloaded from SAM Mobile and was installed via ODIN). My phone's info when I type *#1234# is :

AP: I9505XXUHOJ2

Phone: I9505OLBHOH1

CSC: I9505XXUHOJ2
​

I tried all of your steps but the problem is all the same. For the last two days, My phone is not charging properly. Sometimes, it takes charges sometimes it is not while it is on. If I charge the phone turning off It just like makes slower pulse of battery indicator..That means after connecting the cord, the charging indicator comes with spark like icon then turns off and then turn on again. And thus it is charging very slowly.

If I connect the phone with pc using USB cable no connection indicating sign appearing all the time. No charging icon. But sometimes suddenly it gets connected. Fortunately in download mode it works perfectly.

I will not buy any new phone in next one and a half year so it needs to be repaired. I hope you have understood my problem. Now if you can please help me to get back 3G network. I don't own any repairing box except the USB cable. So any kind of help will be greatly appreciated. Thanks in advancec.

I can confirm this method worked with I9515 (Value Edition). After trying (unsuccesfuly) to enable LTE band 4 and flashing multible roms i completely lost network connection.

Followed the procedure with the nvm file from this post (Network_FIX_v1_z3x.zip):

Thanks a lot [MENTION=1394987]monteiro-ribas[/MENTION]

EDIT: After updating the software (always on stock) the fix wouldn´t stick, so I had to make the procedure again. Tried to re flash the firmware, factory reset and every time de network connection was lost. With this method I could bring back signal every time, but I´m afraid that this isn´t a permanent solution. IMEI seems to be alright. Any suggestions?

[Galaxy Note 4 Q&A, Help & Troubleshooting] Nocturnal86:
Should I sell my N6 to get a note 4? I debated between getting the N6 and note 4 for a while but ultimately the price of the N6 and being nexus convinced me to get it, but I just came across a New sealed note 4 on slick deals for 600 flat. Now at this price I can sell my N6 and get some money back after getting the Note.

What draws me in about the note are ALL the features they just seem cool even if they won't be used daily it makes the N6 seem almost bland (not hating just being opinionated) Don't get me wrong I love the N6 and what it can offer but Ive had the n4 and n5 and at times I get envious of the cool things note users can do that I wish the Nexus line had or could do. Anyone switch and happy with the choice?
[Galaxy Note 4 Q&A, Help & Troubleshooting] tryfound:
The note 4 has a better screen, better battery life, better camera, expandable storage and a replaceable battery. I would get it just based on the battery life alone. You then always have the option of flashing CM for the stock experience if you like. Just be forewarned that Samsung still have the worst optimised software of any of the leading Android manufacturers, you may not appreciate the stutters and delays.
[Galaxy Note 4 Q&A, Help & Troubleshooting] improwise:
I seldom use the pen or the "cool features" but still decided to go for the N4 because of better screen, a somewhat more premium hardware feeling (subjective of course) but most important the finger print scanner. With that, I can replace the unsecured PIN with a more secure password, but still don't have to type it each time. With that said, custom ROM support is still poor compared to the N6 and even the N3. Not that the custom ROMs that exist are bad but quite few.
[Galaxy Note 4 Q&A, Help & Troubleshooting] niyazidk:
Same screen size

I had same problem. I bought note because of more hardware, it is premium hardware. I was close to choose n6 because of screen size. Because both phone has almost same body/case. But if you find a photo that compares both phones with screen on, then you will see that they have actually same size because n6' soft buttons takes much space. You know you have hardware buttons on n4 : )
[Galaxy Note 4 Q&A, Help & Troubleshooting] dragonsamus:
I was torn between both phones but ultimately chose the note because of removable battery, SD card, camera and screen.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Howie Dub:
I ultimately chose the Note 4, but really wanted the Nexus 6. I enjoy rooting, installing different ROMs, messing with the build.prop and system folder, and not having to worry about bricking my phone. It was just too wide and it didn't feel as comfortable to hold as the Note. The screen is also better on the Note. I had an LG G2 and really liked how the whites looked on the LCD screen. While whites on both the Note and Nexus looked tinged compared to the G2, the Note's screen looked less tinged. Also, the Note's lowest brightness level is significantly lower than the Nexus'. I was close to getting the Nexus simply because you could root it and enable the Knock On feature that was removed, but the Note 4 has a feature where you can wave your palm over the camera to turn the screen on. You can always press the home button as well if you don't want to use the power button. Nova Launcher coupled with Secure Settings gives me Knock Off. I haven't quite figured out how to use the S Pen functions for everyday use yet, but I figured if I was going to get a phablet, might as well get one that functions like one, rather than an oversized phone.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Vangelis13:
Bought the Note after using Nexus phones since the nexus one. Had used the Sony z2 for a month and gave it eventually away as "once Nexus, always Nexus".

Note's lack of development & couple of performance perks here & there bothered me a lot so I ordered the nexus 6.

After 5 days usage, I'm back on the note & am looking to sell the nexus. Nothing compares to this phone. Software (yes, touchwizz), build quality, hardware, you name it..

P. S. Size, yes. N6 is a horrendous phone to hold compared to this. Bulky, slippery, really odd.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Jonathan-H:
My Note 4 has serious performance issues at times, with odd slowdowns when it feels like it, and random reboots every now and again, but it's an absolutely solid phone, with a brilliant screen and camera and super loud speaker, and importantly, off screen buttons.

I originally wanted the Nexus 6 but happy I went with this.
