S4 I9505 only 2G (E) mode working. - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
I got a S4 and it had a Chinese modem number (ZHUFNB3), I don't recall whether 4G was working there or not on android 4 but what I did was flash crDroid 7.1.1 and kept the same modem, 4G and 3G was not working here, only 2G. Since I live in Albania, I supposed that it's no wonder that the 4/3G was not working with a Chinese modem, so I downloaded an stock firmware built for Albania well Hungary actually (XXUHOJ4) but it started downloading those Vodafone bloatware in my language so it's good. Problem is, the 4G is still not working and the APN is configured correctly. What could be the cause of this? Could it be that I need to take it where I bought it and have those guys change the entire board?
Thanks in advance!

What is the phone's model # in download mode? Does the model # in download mode and imei match the model # and imei on the label under the battery?

No mater what i receive 4g lte, all i am receiving is 3g.
I would like to know how can I make m phone receive 4g?
I been over 100s of post in this forum couldnt find a related posted.
Same issue
Hi Filter I've had the e330s in the UK on EE since October and 4G/LTE started off working fine but since Android 4.3 I no longer have 4g. The options are there and everything looks great but never switches to 4G.
Looking at your firmware you are a bit behind though as I am too by the looks of it. I'd suggest trying the latest firmware via Odin and possibly Kies if it let's you (might need to try v2 or whatever its called). Firmware links below
Roll on 4.4!

[Q] N910QC CSC Difference

Hi guys.
I'm planning to buy Note 4 in my country, Turkey and they sell sth called N910CQ. I heard that they disabled 4G in that model. I'm not sure if it's about that or not because we don't have 4G here yet. My question is, is it ok to flash N910C stuff to N910CQ? I read that the only difference is CSC and I read that it's about Signals. Thank you.
I am using Note 4 N910CQ - Turkcell device running Russian Firmware (N910C). No issues at all. Device does support LTE unfortunately we don't have a LTE connection.
My phone's about screen says it's N910C not N910CQ

Oh great then! So we can flash kernels and roms for 910C. Do you know what are differences between C and CQ?
There is no differences between C and CQ. Q stands for Turkey nothing else. You can flash C rom to your device.
One thing you should pay attention is when you flash a C firmware instead of original CQ FW, model number shows N910C which makes easier to detect odin flashed firmware if you care about warranity. But anytime you can return to stock CQ with no problem.

Do different official I9505 firmwares have different modems?

I am currently studying in China and a friend of mine from France came back after the last holiday with a GS4 I9505 from home. Apparently she was having trouble getting it to work on Chinese networks, so she took it into some place to have them fix it. Apparently they rooted it, changed the ROM and did who knows what else. After that, she said the phone not only wouldn't connect, but it was also very unstable, crashing constantly. I told her I have a GS4 (I have the I9505G) and could help her restore her phone. She wanted the regular stock Samsung software, no root or anything. So I used Sammobile.com to download a French (NRJ) version of the 5.0.1 firmware and flashed it to the phone. It appeared to work well, but when I put my China Unicom SIM in it, it would only connect to 2G. On my I9505G with stock 5.0, 3G connects without any problems. According to the Wikipedia GS4 page, the 3G frequencies used by the China Unicom variant are also used by the I9505 and I9505G. So when using the same SIM, I assume they should both have access to 3G. Would the French firmware be interfering with this? Do different firmwares have different modems that would be affecting this?
At the very least, I was able to restore the phone and get it to connect to 2G, but if I can completely fix the phone for her, I think that would be preferable. Any advice or shared knowledge about this issue is much appreciated.
i have S4 three UK version and i downloaded uk lollipop with different csc and pda and modem, but still it works like a charm

N9108V - Note 4 for China Mobile version. 3G and LTE not working in Europe (Greece)

Hello everyone,
A Note 4 N9108V end up to my hands, but after using it i realised it cannot properly operate in my network.
It is a snapdragon variant, single-sim version for China Mobile, has lot of Chinese stuff totally useless if you are outside China and does not have Google apps also.
I manage to root the device, install custom CWM recovery, install a MIUI7 ROM that is quite good, install Google but still have problem with 3G coverage (and LTE ofcourse since in China LTE is different than EU)
I have 3G coverage, but if i will move to another location i will not be able to make calls, and i will also appear as unreachable if someone is calling me. Also data connection will not work. Later, it may work correctly for a while.
In GSM mode is working perfectly
I took it to a local repair center to check for hardware problem, they say that it is probably the baseband (modem) software that is designed specific for the China Mobile network, or there is a bug.
I tried all the available official ROMs and modems for this device (4.4.4, 5.0.1, 5.1.1) but nothing improved.
The only thing i manage to do is to have this amazing phone working only in GSM mode....
It is like having a Ferrari with pedals.
I am thinking if it is somehow possible to load the modem file for the EU model (N910F), and this may "unlock" the needed frequencies to operate correctly. Or even, if it possible to load the entire N910F or similar non-branded Note 4 formware to the phone, since i suppose the hardware is the same.
I tried to load this modem file and the n910F firmware with Odin but is not accepted, the procedure failed.
Any ideas, proposals etc?? (except of hammering the device, this will be my last option) :laugh:
Thanks in advance

Note 3 N9005 LTE 4G Doesn't Work, Do I need CSC change?

I've searched the forums and no one seems to have an exact FIX for my issue. So I have a Galaxy Note 3 N9005 32GB black version, the phone works well in 3G, never had an issue with it but now my network provider recently upgraded their plan and offers 4G internet but my phone doesn't want to connect. The provider offers 4G through BAND 1 2100MHz and Note 3 N9005 does have that band but it doesn't want to connect. It only works on 3G and when I enable Mobile Data it says H+! Not once has it connected to 4G!
I wanna mention that my friend has the exact same N9005 phone and his phone works on 4G all the time. Both of us have the same contract with the same network provider!
The only difference between our phones is the CSC region, we have different CSC. MY SIM card works in 4G on his Note 3 and his sim card doesn't work on 4G on my phone. (we exchanged the SIM cards for testing). So the problem is from my phone not from the SIM card. My phone is also original, its not a Chinese clone! Its confirmed with "Samsung Phone Info" app from Play Store.
Here's a few things I already did that some of you may be inclined to recommend to me:
1 - My APN is correctly set
2 - I am on official stock Android Lollipop 5.0 latest version and the phone is not rooted
3 - I already did a factory reset + wipe cache partition
4 - I saw others suggesting that people may not be in the range of a 4G tower! Not the case! Like I said, I switched the SIM cards with my friend on a public bench, out in the open, not even behind walls. Of course and his phone connects to 4G with his SIM card and also with MY SIM card while my phone doesn't connect to 4G with neither of these SIM cards.
5 - In Mobile Networks > Network Mode, my phone is of course already set on 4G/3G/2G (auto connect) and by the way, my friend's Note 3 says LTE/WCDMA/GSM (auto connect) instead of 4G/3G/2G with the same language set on both phones. Why?? I know its the same thing and I know 4G stands for LTE and 3G for WCDMA but why does it appear differently on these phones?
6 - I already went to Service Mode via *#0011# and manually selected BAND 1 LTE, it says "no service" or "emergency calls only" if I do that so I switched back to "Automatic"
So what the heck is going on? This phone is giving me headaches! I'm close to smashing my phone! After this I sweared to my self this is the last Samsung phone I ever buy. Probably I will be switching to Asus or Lenovo in the future. Or any other phone that does NOT have this CSC BS! This CSC thing is a complete rip-off!
Im thinking that the problem could be my CSC perhaps?? My friend's Note 3 N9005 has a COA CSC (Cosmote Romania) and I have a XEF CSC (Unbranded France). Both phones are factory unlocked and work in all networks. They are not branded by any phone maker! His COA CSC is unbranded. Yes it belongs to a phone retailer but that retailer doesn't brand their phones, no bloatware, no SIM lock. If you buy a phone from Cosmote (with COA CSC) it works in all networks, unlike Vodafone or Orange who lock their phones and brand them.
What should I do? Should I attempt to change my CSC? If so, how? My phone warranty has expired a long time ago, so I shouldn't care that much about triggering Knox though not triggering it would be preferred.
Which path should I pursue? Should I simply use ODIN and flash a STOCK COA CSC (Cosmote Romania) or STOCK ROM CSC (Unbranded Romania) from SamMobile.com with the latest version of Lollipop? Would this trigger Knox? Will it affect my all networks unlocked status? I mean, I won't have to unlock it after that, right???
OR should I ROOT my phone, change CSC, then UNROOT? If so do you know of any method to root Lollipop 5.0 without triggering Knox?
What do you guys think? Whats the problem with my phone? Why doesn't it work on 4G? Because of CSC? Or is it something else?
Thanks!
The best way to confirm the model # would be to boot into Odin mode and look there.

What do you mean? Can you be more specific? I already told you my model number, its N9005!! Do you want a screenshot?
Dear OP, have you tried the other Samsung secret code? *#2263# then program it to accept LTE only.
That's the only foolproof way to get the Note to connect to LTE. In my country I only get 2-3 of the 5 LTE bars, so the Note wouldn't automatically connect to LTE or immediately stoop down to 3G through the settings. That specific secret code and setting is LITERALLY THE ONLY WAY TO GET MY NOTE 3 TO CONNECT TO LTE IN MY EXPERIENCE.
If that still doesn't get your phone to run LTE, either your carrier is whack or your phone is, and no amount of Cyanogenmod can fix it because your hardware modem inside the phone might be whack and you can't really do anything if that's the case...

I have already explained that there is nothing wrong with my carrier because I switched my SIM card with my friend's phone who has exactly the same N9005 model and it perfectly works on 4G on his phone. The only difference I could find in our phones is the CSC.
As for the other suggestion you sent me, I already said that I've been to SERVICE MODE. The code you've given me does nothing on my phone but as I can see from your screenshots, it gets you to SERVICE MODE. I've already been there through *#0011# switched to LTE/GSM only or LTE/WCMA only and I've explained that it still doesn't do anything.
Can someone please answer me this? Would it help if I change the CSC? Could this be the problem I'm having???
It may help if your CSC is changed it can do no harm .

Booting into download mode will confirm the model #. Looking under the ROM's settings is not guaranteed to display the proper model #.
Both phones are running the same ROM, bootloader, and modem?

Yes confirmed, same model, same baseband, same everything. The only thing different is the CSC. So whats next?
Did you try changing the csc by dialling *#272*enter IMEI#? Not sure if this method will work for your model of note 3.

No I haven't I'm trying now. Wow if this works Im gonna buy you a beer!
It doesn't work! just my luck! I entered this code: *#272*IMEI-number# and pressed call button, it says "Connection problem or invalid MMI code."
I just tried it on my Note 2 and S4 and it works. Maybe the phone is not running a multi-csc stock ROM?
I don't have a note 3 to try.

Perhaps the code you gave me only works on older version of Android such as KitKat or whatever you have on Note 2... anyway Im using Samsung Phone Info app from Play Store and my CSC is XEF and under Available CSC Codes there is a bunch of CSC codes. Here I've made a sccreenshot:
From as far as I know there are only 2 ways to change the CSC: root or flash a different stock ROM
Yes, the note 2 has kit kat but the s4 is running stock lollipop.

Well unfortunately the code doesn't work on my phone. Anyway if you know for a fact, could you tell me this? Is it safe to reflash another STOCK rom from sammobile? Will it affect my phone in any way?
Thanks
Yes, it is safe to flash stock ROMs from sammobile.com.
I just flashed a local stock ROM and guess what, when I go to Phone Info app it still shows the same CSC! I still have XEF CSC, how can this be? Why hasn't the CSC change?
After flashing the stock rom, did you try the csc code I mentioned? Same thing happens when I flash a Rogers carrier rom over a Telus carrier rom. Once I select telus as the carrier from the csc menu, the Rogers app will disappear and the Telus app appears.
Ok after further researching I found a lot of interesting stuff so I'm gonna write it all down for other people who may need it in the future.
1 - If you have a multi-CSC phone and you flash a different CSC but which is in your "Available CSC" list but which you cannot choose or change without root, your CSC will NOT change. For example: I have flashed ROM CSC (Open Romania) on my XEF CSC (Open France) and guess what after the flash was successful and all, the CSC didn't change! It was still on XEF because ROM was in my "available list".
2 - If you try to flash a different CSC which is NOT in your list, then Odin will FAIL and softly brick your phone. For example: I got my phone bricked, trying to flash 2 CSCs which are not in my "available list": COA (Cosmote Romania) and DBT (Open Germany). In order to fix this issue all you have to do is to reflash YOUR OWN CSC, in my case it was XEF. Or you can even flash one of those CSC which are "available" or compatible so to say, such as "ROM" for example.
This is the firmware I currently have on my phone:
http://www.sammobile.com/firmwares/download/61565/N9005XXUGBOK6_N9005OXXGBOJ2_XEF/
These are the two firmwares I tried to flash on my phone, hoping to replace XEF with:
http://www.sammobile.com/firmwares/download/63441/N9005XXUGBOK6_N9005COAGBOK1_COA/
http://www.sammobile.com/firmwares/download/61464/N9005XXUGBOK6_N9005DBTGBOI1_DBT/
BOTH FAILED in Odin!
There are ONLY 2 ways to change the CSC on newer Samsung phones. Most guides online are based on KitKat 4.4 or older guides but for 5.0 Lollipop or even NEWER there are ONLY 2 ways to change your CSC:
1 - Root your phone and change the CSC. There are plenty of guides on how to do that online.
2 - You can avoid rooting your phone and use Odin instead, BUT accompanied by your stock firmware, you will also have to find and use a PIT file because Samsung as of 5.0 Lollipop uses different partitions for all the different regions. HOWEVER messing with PIT files is super risky and it can permanently brick your phone so its just better to root your phone instead! Dont waste your time trying to flash different regions/csc which is not in your available csc list, it won't work!
What can I say? Samsung is trying hard to block their users from changing their CSC... Why? They prefer their users buy new phones. Its pure greed yes but its what it is... For me, this was the last Samsung phone I ever buy. Im truly disappointed.
