CDMA US Versions Don't flash Roms - Galaxy S 4 Mini Q&A, Help & Troubleshooting

So for the past month or so i have been trying to find a working Rom for my SCH-R890 (US Cellular) i have flashed all Roms i can find including cyanogenmod,Pac-mam Rom, and Aviator Rom, non of them work because after flashing I end up with a null imei and a lost of network service. It was very frustrating for me since i broken two phone but thank good for the *228 feature on US Cellular that can restore my setting. After trying to find a solution to this mess i thought that it was my imei but after investigating some more i notice that these rom were for the international version. That when it hit me!! The international version all work on GSM System!!! So that explains why every time you flash a rom on the CDMA phone you loss your imei and phone number and connection. So for the US variants that run on CDMA don't flash any Roms that are for the i9195 because it will leave your phone with no network. I belive if we message the developers of the Roms then they could be able to create a CDMA version of there roms that would work for all CDMA version of this phone:fingers-crossed:

and what happens if un flash everything but the modem?

That's what I have tried to do
But it's more of I can't since I can't find my specific modem file because I can't find it anywhere. But if you were to test it your self if you could and provide feedback would be much appreciated

After you flash the ROM connect to WiFi and download advanced signal Status and switch it to CDMA. That's what I did the only issue I'm having is no sound and buttons don't work so I'll searching for a kernel that would fix that for sprint galaxy s4mini. Other than that everything works fine WiFi NFC camera. Everything but sound and back button and menu. So to fix them issues u use on screen buttons

[Q] network problem after rooting installing roms

The other day I took the plunge and decided to root my phone and install some ROMs. It was all going well until I started noticing that I wasn't able to make/receive calls or texts. I had gio pro 1.4 installed when I first noticed this problem and I had read that installing cyanogenmod 7.2 had helped someone with a similar issue so I installed it.
Now I have cnmod 7.2 installed with the same problem and with my carrier name changed from virgin to bell. If I restart my phone I am able to call and send messages for a few minutes but then craps out again.
Hopefully someone can help me
Thanks in advance!
no network problem
unfortunately u are having the same issue as me you have to select use 2g only which is only good if you are on a network that supports 2g the nv data file become corrupt somehow and you lose 3g capability i am trying to figure away to fix the gio but to no avail right now

Actually I found out why I was having this problem recently. Turns out I have a different model of the gio (gt-5660M) . When I installed gio pro 1.4 I completely overwrote my stock firmware including the baseband so it screwed up my network settings. I had to find my stock firmware, flash it using Odin and then I just installed clockwork recovery and flashed cyanogenmod 7.2 using that. It's been fine working since then.
Thanks anyway!
well atleast your lucky i restored my original software and it has the right modem when i do a network search it picks up the 3g networks just wont connect to them
Yes, I accidentally did the same to my GT-S5660M. What I did was reflashed the stock ROM and then rooted, installed CWM recovery, and flashed a custom ROM, being careful not to override the baseband. Thankfully the ROM I flashed used CWM recovery and not Odin, and I didn't have to worry about a thing.

[Q] Cellular network download issue

Here's the problem.
I installed many roms and kernels on my gnex since i bought it. Lately i came across a strange problem. If i install codename android, gummynex or foxhound with any kernel or radio i'm unable to download over cellular network. If i install android revolution hd or cyanogenmod 9 nightly its work even if i change the kernel or radio ??
Now when i say it doesnt download...my signals bar are max out on hspa+ but it aint blue, its gray. Usually when there is activity an arrows appears to show it. In my case case i only see the up arrow. I also when look under the *#*#4636#*#* menu and i data being uploaded but download is a 0. Ping test didnt work. Signal strength is around -85db. Preferred network is set to GSM/CDMA auto (PRL). I also tried to change it to GSM auto (PRL) and GSM only without success. I played with airplane mode. I tried turning on and off cellular data. Nothing works.
For now I'm on CyanogenMod 9 Nightly Build with Franco Kernel 16.2 and Gaaps 4.0.4 with XXKL1 radio. I have a Bell GSM Galaxy Nexus and my carrier is Rogers.
Does anyone have an idea of to fix it ?
P.S. I tried to wipe data/cache + dalvik + system.
I'd check your APN settings - sounds like some ROMs have the right ones, while the others may not.
Settings --. More --> Mobile networks --> Access Point Names
You can google around for the correct APN settings for Rogers. Here's the first hit I found: http://www.nexusoneforum.net/forum/...gers-wireless-apn-settings-data-mms-here.html
Thx a lot ! It worked ! Thx for your quick reply : )
Thnx since the OP didnt.
Bumping this.
This is my exact issue on T-mo USA. On nearly all radios, that is if I get a signal at all. Upload only no download. I've tried AOKP, Rooted deodexed icl53f, Slim, Liquid. Problem persists. What really chaps my ass is that it came with xxkk6 and now that one has no signal bars at all......
At least I can still make calls and send messages with no download radios.
your APN settings are wrong. read the how in this thread
I have apn set to these settings:
http://forum.xda-developers.com/showpost.php?p=21630221&postcount=1
Which are the same ones generated by using the "Reset to default" option. And what are listed in numerous other sources.
It sounds more like a firmware or hardware issue than an APN problem to me. You've said you tried a few different radio firmwares - have you tried UGLA4? I've had really nice results on T-Mobile US with that.
I'd try loading up the factory image with UGLA4 and see if that works for you. If that still doesn't play nice, you may need to look into getting a replacement.

Thanks for the info. Is there by chance an odin flashable for the GSM icl53f? I keep only returning hits for the CDMA version.

Not for ODIN, but you can get the official Google factory image here: https://dl.google.com/dl/android/aosp/yakju-icl53f-factory-89fccaac.tgz
You can extract it and flash the "image-yakju-icl53f.zip" file in fastboot:
Code:
> fastboot flash update -w image-yakju-icl53f.zip
I was able to restore but on xxkk6 I have no signal to speak of. Will have to go the Samsung route. The postal service has already lost one $350 dollar phone this month. So I'm very hesitant to be honest.

Impossible to get network operator

I flashed CM10.1 on my S3 and had the same problem as others where data was intermittent. It worked for some time and after one nightly, I lost my IMEI. So I got back to stock, used the procedure with QPST and got back my IMEI. I got back to cm10.1 and unsurprisingly, I had a hard time having data. But worst off, I had a hard time having cell connection anymore, not even voice or sms. Tried AOKP without any luck. Tried different modems, not luck either. Now I went back to stock and still doesn't work. There's something that is not resetted between flash of ROM that keeps messing up my connection. I also found out that only one network provider is ever found, one is Rogers Wireless (I'm with Bell), or one is EXT. But never any other provider is ever found. And also in *#*#4636#*#* under phone info I can'T change the radio band like I can on the phone of my girlfriend.
So there it is. I'm stuck. I don't really want to buy another phone. It is a software issue for sure. But how can we solve that? Is there any way to restore the EFS to factory default? Could it be buried there? What is the ERI? Could it be that? My stock ROm says that it can't get the ERI version.
Any help is welcome.
my stock telus ERI is unavailable but i think thats normal... i have no problems
from what i understand imei and apn settings are the things to check into

IMEI and APN are good. IMEI will get me data, but I can't even get a cell connection now. No radio at all.
whats your radio band set to?
if i set mine to anything but automatic it wont find networks like yours..
*#*#4636#*#* dont work on my telus s3.
i use a different method
*#197328460# then
UMTS > Debug Screen > Phone control > Network Control > Band selection >
Automatic...
beware what you change in here as there is no return to default

Neither of the two works. *#*#4636#*#* was working with CM10/10.1 and AOKP. But not with stock. And the one you suggest after is not working either.
But I remember going ot *#*#4636#*#* before flashing stock rom and I wasn't able to selet any band. On my girlfriend's android phone (HTC) I can.
if it were me.. i would try reflashing stock again... after flashing stock do a factory reset thru recovery... seems to help for clean stock setup.
if still no network i would check that band selection is set to automatic.
maybe someone else with more experience would have a better idea.
you mentioned you changed your band selection and now cant change it back.
i dont think flashing stock changes this.
i think that might be your problem.
ifso you first need to fix phone to use *# code... i have no idea why its not working
it works on my stock telus 4.0.4 and 4.1.1
maybe bell blocks from using *#code?

if i were u i would first try your girls sim in your phone and vise versa and if no luck do the qpst instructions to regain LTE not imei .and if u still cant manually find network operator after that i would format both sd cards and odin back to stock rooted and do the imei injection again for the hell of it and the LTE fix ..and stay on stock rooted or 4.1.2 until u get this figured out cause 4.2 builds are gonna have more probs then 4.1...I know u are having cell connect probs and these instructions are for imei and data but it sounds like your out of options....i lost imei once and had to manually inject with qpst and my reception was one bar til i did the LTE fix and it worked awesome..one more thing is my phone will not select a radio band ever unless i manually select my network operator first or i have no sim card in phone..i have also had sim cards crap out for no apparent reason..good luck

Thanks for your answer. Really appreciated. I've flashed so much time that I don't see the point of doing it again. I also had, at some point, to inject my IMEI and it worked with QPST.
What I find really strange is that a stock reflash doesn't put everything back to when I bought the phone. Funny thing, after the flash, it knew what my Wi-Fi router password was! So obviously there are some part of the config that is not overwritten. Which I find odd.
I also started playing with the service menu and found a lot of settings for the radio band. No luck yet.

Your WiFi password could have been restored by google just like it puts your contact info back.
If you are doing a Odin to stock that should wipe it clean.

This thing is so strange. There's only one network that my phone can see now, and it is 302720. Bell is 302610. No other network is visible. And since I'm with Bell, then I can't connect to 302720. I'm in for emergency calls only. That's why I thought it may have to do with radio. But it seems Rogers (302720) and Bell use the same bands. A channel maybe? But this should be all automatic! It's a pretty stupid bug let me tell you!
Maybe a SIM card issue? That would be quite a coincidence that it happen exactly when I'm playing with ROMs...

Ah that's a good possibility. I didn't know it was saving passwords as well.
So if it wipes clean, how come this bug stays? There is obviously something that is not wiped and overwritten or else it would work.

When you go to info about your phone, in status you usually have your IMEI number. It'll show 0 if it's corrupted. Or sometimes it's a generic IMEI dans is used when the real one is unknown. It's 049 something I think.
Without an IMEI number you can do phone call. But you'll never have a data connection.

[HELP] My phone constantly switches to CDMA and than has no signal

Hello I bought my phone off of ebay it was already flashed with tasks rom when I got it and the only problem I have which is very annoying is that it constantly switches from LTE/GSM/CDMA to CDMA only when I goto settings>more>mobile networks...Whenever there is no signal it is set to CDMA only I'm not sure what the problem is but its very frustrurating when I cant make calls when I need to...Is this a known problem? Will I have to revert back to stock?

Just checked although its named after the core one it has the LTE settings I've been using LTE fine
Even though the settings were the same I still made a new profile for LTE and its having the same problems Sometimes toggling airplane mode or restarting the phone seems to fix it
Again the problem is that the phone constantly loses signal and the mobile network setting says "CDMA only" if I change it back to LTE/GSM/CDMA sometimes the signal will come back

the fact that your gsm device has built in options for cdma and consistently tries switching to cdma (which is probably why you lose service) tells me something needs to change. on your i747m, what is your baseband version? also, what is your android/task650 release?

oh wow, so you literally just bought that on ebay. unfortunately, when buying a device thats already rooted and running a custom ROM, you dont know the procedures used when that ROM was installed. there's a wrong and right way to do it so as to have a smooth running phone with little or no complications. I would make a backup in recovery and then try a different modem or reflash the ROM and google apps (gapps) again. is the ROM and gapps files (.zips) still on the phone?

I'll try that but weird thing...I remember reading somewhere too many open apps may cause signal problems and I just killed all open apps when the signal dropped and about 15 secs later signal was back dont know if this was the problem for sure I'll try again if it happens see if maybe I can narrow it down to a particular app or process

[Q] CM11.0, 20140608, M7 Snapshot - Unable to get signal from radio

I started to experiment with different custom ROMs available for the d2att (now, apparently called the d2lte). My phone is using TeamWin 2.6.3.1 for recovery, I have been using it for everything. So far I have only been familiar with two certain ROMs: Cyanogenmod and CarbonROM. I have not flashed anything except for the recovery.
I complete the installation of my new ROM by first wiping cache, dalvik, data and system. My ROMs are stored on an external SD.
CarbonROM was the first one to be installed, but I found it quite buggy and unstable. I have since been using different snapshots of CM to test functionality and stability...since I plan to hang up my LG G2 and start using my SGS3 w/7200mAh battery as my daily phone. So it needs to be very reliable. I also enjoy picking with settings so the more settings the better.
So, question number #1:
When I install CM the normal way, add my APN, and select the proper mobile network mode, how come I cannot get a signal, no matter what I try? I have searched around many forums for the answer to this...many have nothing to do with my problem or are using different phones. I can confirm my SIM card works, as it was used in my LG G2. Carrier is Virgin Mobile Canada. Network mode is GSM/WCDMA Auto. It does not work with any other modes including Global.
Q #2:
If I plan on using custom KK (4.4.2) ROMs, is there anything extra I need to flash to the phone in order for the cell radio to work successfully? When I researched this, I found lots of people talking about flashing a custom bootloader, but I could not find an exact answer to my question. I would rather not brick my phone by attempting this blindly.
Q #3:
Since I am looking for a reliable custom ROM, is CM the best developer to choose? Is there a more reliable ROM out there?
Mike
EDIT: I did more reaseach on bootloaders and modem firmware and found that my bootloader is already at the most recent version. I did find however that my modem firmware was out of date, so I updated from UEMK5 to UEND3. This however did not solve my problem as I still have no service...
I am contemplating now about starting from scratch and wiping my internal storage... will this help or is it unnecessary?
For question # 1, do you have a proper imei after installing CM11? You can check it in the dialer by typing in *#06#.
For question #2, the modem must be compatible with the bootloader. Custom ROMs will only install if the phone has a compatible bootloader.
For question #2, I prefer Validus which is an AOSP-based ROM.

I have an IMEI number. That is what has me kind of confused...everything is there to show signal, it's just that it will not pick up a tower. When I throw a SIM card in it recognizes it. One thing to also mention is it pins the signal at 0, -1, or 258692378... or another outrageous number.

But... I had a funny feeling, so I went into stock android recovery and wiped cache...and voila, service!
Only problem is, I'm losing it almost constantly. The only way to fix it is by wiping the cache, but I can't keep doing that whenever I lose service.
Will I be okay to flash the custom recovery and custom ROM at this point?
Do you have the latest modem installed?

If you are still on the Stock TW ROM here is a method to try. It will clear most of your mobile data problems.
1. Enter the Samsung service mode by typing this code into the dial pad *#197328640#
2. Then go to Mainmenu>UMTS>Common>NV REBUILD>NV REBUILD> (Important: don't exit the menu yet!)
3. Wait 30+ sec
4. Long press power button and select "Restart / Reboot"
5. Now check your GPS from any software that may use GPS like "Maps" or "GPS Status"

EDIT: Afterwards you should be good to go on your custom ROM. This issue seems to have arisen when a d2lte build broke most people's LTE/Mobile data.

Yea at this point I am stumped. I guess its a hardware issue. But before calling quits what is your baseband and boot loader?

You're running the most recent release so I'm not sure what's causing the issue.

I have found the problem with the service. I live in an area where signal is not too great. My LG G2 has a tendency to pick up the correct tower for my area, but my Galaxy S3 does not choose the same tower... It looks for one in a completely different direction.
Forgive me, this thread is going to take a bit of a turn.
Is there any way to choose which cell tower the phone connects to? In my area there is one directly east and the other is directly west. I need the western tower in order to make/receive calls/text and in order to get any data reception. Right now where my phone sits, it does not connect to the western tower so I cannot use it. I used OpenSignal to observe which tower both phones connect to.
The other issue I found is my extended battery (Anker 7200) also interferes with reception quite a bit. In town, it's not noticeable. But out on my acreage it stops my phone from getting any signal. I compared it to my LG G2 and my Galaxy S3 with the old 2100mAh battery. The G2 hovers around -95, S3 w/OEM battery at -101 and the S3 w/Anker battery at -113 (no service).

Try changing the mode to LTE only under your settings. This may force the stronger connection.

Unfortunately that won't work either. In my area I can only pick up HSPA....

Hmm. Out of curiosity, have you tried a different ROM on 4.4.2? I've had weird issues with ROMs and signal, ie MIUI caused me to have my signal cut in and out at random intervals. Worth a shot at least. I've been using SlimKat if you want one for reference (probably the quickest download due to size).
Unfortunately all I can suggest is trying to play with tasker and seeing if you can get it to skip over the crap tower, but to my knowledge there's no way to prevent connection to said tower.
I guess if you wanna get into a gray area you could modify said tower....but I claim no responsibility for your actions with that

I've been using Liquidsmooth the past few nights and am losing signal more than ever.
Would the OS control how the modem is used? I would think that it's hardware only that changes how and when you get service.
I'm going to try the UEND3 modem firmware and see if that makes a difference. Also going to try SlimKat like you suggested.
