(Need Help) Flashing rom, modem, and recovery - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

HI many name is Sameer. I bought Samsung S4 from a dealer who sells unlocked and rooted phone.
HE said to me its from outside and its unlocked plus rooted. so i was glad its rooted and unlocked now the problem is i dont see the super su app on the phone but i can use apps that require root access.(weird)
Now when i used to use htc explorer (pico) I never had to install any modems or some baseband thingy so i'm a little confused here.
Goals; I want to install this Rom: JFLTE-GPE
This rom requires latest modem and twrp
Twrp is no biggy i can install it using twrp manager, but i don't know if i can install a modem and i don't even know if i even have to cuz the guy who gave me(mobile) must have installed some modem to make my domestic sim work i live outside US
I want someone to help me on how to install modem and to tell me weither i have to install one or not.
Also i want to know if i install the rom will my device lock and i won't be able to use my domestic sim
I know there are a lot of guides out there, i'm here cuz i couldn't figure them out.
Forgive me for my bad English.
SS of about device for all the info: Screen Shot

I am not absolutely sure about the domestic lock stuff, but when I got my L720, I flashed an entire stock firmware on it, updating the modem, system and everything in the process, yet the phone capability isn't affected in any way. I flashed CM12.1 on it, made a small patch to jump between GSM and CDMA (GPe probably won't need it), and all is well.
Assuming that you don't need to worry about the network problems, you need to learn how to use Odin, and find a latest modem file that's Odin-flashable. Or to save this trouble, you can flash a full latest firmware just like what I did, although this means you'll also have to re-flash your TWRP recovery.
One tip: TWRP is also flashable from Odin, and this is the suggested method.

To almost bricked and back on US Cellular version

Thought I'd share my experience in case it would help anyone.
Got a good deal on a new used US Cellular version tab. Hadn't come here yet to check things figuring all tabs would be the same.... wrong obviously.
First, because not everyone necessarily clearly mentions the difference between the GSM and CDMA versions, I almost went down the wrong path and tried to load a GSM rom. Caught that luckily in time. Rooting sucked as Kies would not, with 6 different computers and just as many different versions of Kies, recognize my device. Luckily I stumbled on the Z4root app which worked great.
All is good, but of course, no one mentions the us cellular version at all when it comes to roms. Studied up and noticed the model numbers and specs between us cellular version and verizon version matched. Great. Loaded beta clockwork mod for verizon, but only the stock recovery would come up when I tried to get into recovery.
Decided to load the voodoo kernal for cdma verizon. This is where it got ugly. Wouldn't convert partition to ext4 and just sat there. Took creators advice and booted into recovery. Suprisingly, it now went to the clockwork mod recovery, but nothing I did there helped, so I rebooted into recovery from clockwork mod recovery as per the instructions so I could do a data wipe and factory reset. Not all I had was a boot loop and it would no longer even go into recovery. Pretty sure I was screwed at this point. Only thing I had going for me was that I could still get into download mode. Got lucky and found the files necessary to go to bone stock verizon vie heimdall. Loaded them up and rebooted. A little hairy, but then I had a running system again. Since I knew I could always redo that, I decided to load the voodoo kernal again and this time it worked (maybe because my system was now basically verizon???).
Anyways, if anyone needs the files to go back to stock, I do have them and would be more than willing to share. I know one thing, if it wasn't for the wealth of information here I would have a bricked tab right now.
So I just bought a used US Cellular tab and wish I'd understood there would be issues.
I just rooted via z4Root as well and now don't know what to do. Were you able to flash any ROMs after getting into recovery? I'd imagine Verizon Roms might work?
I don't care about cellular data as I'm using it as wifi only.
Would you be kind enough to share the stock rom you mentioned? I've run into problems restoring my US Cellular GT. Thanks!
This is the exact same thing that happened to me as well except that I have a vzw tab.
I used sgs kernal to flash which went successful then tried to load a rom through cwm and got stuck in the boot screen.
I was able to go into download mode but had no idea how to use heimdall nor did I know what files I needed.
Luckly I bought through vzw 13 days ago so I just went in and exhanged it.
Wanna try again but would like to have the stock files needed to restore my tab in case I soft brick it again.
Can you please email me the files to [email protected]???
Yes please share the stock files
I would also like to request stock file as well. Thanks!!!!

Bricked? No custom or stock rom?

ive had my note 3 for awhile and have avoided rooting or modding it in any way for quite sometime, but i rooted the stock firmware i believe it was 4.4.2???? im not 100% with towelroot and i was able to install safestrap thats where my success ended I didnt make any backups for whatever dumb reason and also it has been quite sometime since modding any phones, now my phone wont boot into any rom ive tried i have tried two so far and i cant get the factory one back, half the time i cant install roms and the rest of the time they work but they wont boot ive tried creating rom slots but those dont work, read somewhere they arent supported in 4.4.2 ???? and when i tried overwriting the factory it still didnt work, now my phone wont boot into anything anymore and im not quite sure what i did wrong and if there is any way to fix it, i would have like to install knoxraid on this phone since it supposedely fixes the gps issues lots of people have when i try to install that particular rom i get a successful message but then when i wipe cache/dalvik it work and then i hit reboot nothing happens, all i get is a black screen oh and its says that safestrap is disabled

May I know which variant on Note3 you are using.
and what's the OS version? 4.3? or 4.4.2 or 4.4.4
what's your region (CSC).??
I would suggest you to go into download mode and download appropriate stock firmware from SamMobile or from Samsung Updates (Link for N9005) and flash Stock ROM using ODIN.
Thanks.

[Q] ANNOYING S4!! Help needed

Ok guys, here's the deal. i bought a secondhand s4 which was advertised as a google edition. it has a couple of annoying issues, first i noticed it switching itself off and on. the worst problem with it is that when my battery goes reeeally dead it just bootloops when i have recharged. the only way i can get it back on is to start it in recovery mode (which is clockworkmod v6.0.4.4) then do a factory wipe. so yeah thats a major pain. the s4 itself is a red model and behind the battery it says its a gt-19505, however in the settings on the phone it says its a gt-19505g.
my goal is to install an official firmware if possible that i may be able to update easily, the worry that i have is that i dont know if it would then accept my network as although it appears to run google edition custom firmware it may not once i install something official on it. this may be a nooby statement i know but a noob i am lol.
if its at all possible could i keep the cwm recovery?
and if its any help when i load the other boot loader thingy (with the green android on it) in the top left it says gt-19505, im just sayin cus im sure its vital which ever this phone actually is.
here are as many details as i can give but please ask if im missing anything
ANDROID VERSION 4.4.2
KERNEL VERSION 3.4.0-faux123-KK44-GE-Custom
[email protected]omain #20
Sun Dec 1 02:30:28 CST 2013
BASEBAND VERSION 19505XXUFNA1
BUILD NUMBER KOT49H.S001.131204
also upon booting in the top left it says "kernel is not seandroid enforcing
set warranty bit:kernel"
THANKS FOR YOUR TIME And please tell me where to start as i tried updating it via kies to fix it but it just wont connect, i assume due to custom firmware.
The Google Play Edition S4 devices didn't come in any color but white. Therefore, this is an I9505 with a custom ROM on it. The download mode screen reading GT-I9505 confirmed it.
Since this is an I9505 and not an I9505G, the main question is whether this device will work with your SIM card. For that, simply insert your SIM card and boot the device. If you get signal, you're good. Otherwise you'll have to unlock the device, either by purchasing an unlock code from one of the sites that sells them, or by trying the unlock methods available on the forums.
This will also help answer the question of which stock ROM you can install on the device. If the S4 doesn't prompt you to unlock the device, then you can install one of the unbranded S4 ROMs available on sammobile.com. After that, you can put the recovery of your choice on the S4, though I recommend TWRP over the other options.
Thanks for your help. I'm a little confused though, at the moment with this custom google edition ROM it does take my sim, in fact I bet it takes any sim, I heard that was a feature of google play devices. What I meant was after I install the stock ROM will it then not take my sim. So if it has already been unlocked How would I know which ROM to install? As I now know its not a google edition, is it possible to install an official google edition ROM? Do i use this download mode, Odin, or cwm to install a firmware. I'm just not sure what my starting point is. I don't wanna follow someone's guide yet to installing something just in case I'm jumping the gun and need to uninstall this custom ROM somehow.
Sorry for asking questions that I'm sure seem dumb I'm really just trying to learn at the moment I'm green as they come with android. BTW thanks for your suggestions so far, you def seem like you know what you're talking about, cheers
Google Play devices are carrier unlocked, but this is not a Google Play Edition S4. Therefore the device was carrier unlocked at some point in its past. The unknown here is how the original owner unlocked the device. If he or she used the unlocking methods found on XDA there is a chance the lock will be lost when installing a stock ROM.
If the S4 is unlocked, you aren't restricted to a particular region and can install any I9505 ROM using Odin, though I recommend the carrier unbranded ROMs. You cannot install a stock Google Play Edition ROM on the device as the model number of a GPE device is not the same as the device you have. However, you're already rooted and have a custom recovery installed. In I9505 Development here on XDA there is a Google Play Edition ROM that can be installed on your device. Download it to your S4, wipe everything in recovery, then flash the ROM's flashable zip in recovery. I've used said ROM and it works quite well.
OK I have found the 5.0.1 ge ROM , but in there it says I must use latest recovery or whatever plus it recommended one different to mine, is it safe to install using my version of cwm or do I need to learn how to change it??
Deleted by user
TWRP is recommended as there are people who are still maintaining it, unlike Clockworkmod and Philz. While you probably can get the ROM installed using the version of Clockworkmod you have, learning how to change recoveries is useful.
OK thank you for all your help my friend, I will now find out how to do this, I'm sure there is a section on this somewhere, BTW I think you are right about my device being rooted, but I wanted to check and I followed a guide and used super su but apparently its not rooted so I guess something must've gone wrong. Bit scary if I try to change my recovery or my firmware and this causes a brick hmmmmm
It's virtually impossible to brick the S4, especially as the recovery is flashed through Odin.
Phew that's a relief. Thanks man.... Well I'm gonna just risk using cwm for now as I'm new to this........ Thanks a whole lot for your time I really mean that.

I want to, I really do but I'm struggling here. Before I wrote that last comment I tried to find a guide on this forum for swapping to twrp, but couldn't and didn't wanna bug this guy as he had helped enough. Anyway I went to the place he told me and have hit another wall anyway because I don't know how to use the firmware the relevant kernel or the git. My life is so busy and I'm getting about an hour on this subject a day and its gonna take forever lol
If you can help me on my way even a little its much appreciated, I would like to use twrp and the 5.0.1 ge plus the right kernel of course

Follow the Odin guide. It's excactly the same when you flashed CWM.
@Lennyz1988: The S4 was bought secondhand and already had CWM on it from the original owner.
@killfrenzy: Follow the guide Lenny mentioned, but don't worry about the second paragraph. Our device isn't one of those that restores the original recovery on boot.
ok will do, i just tried the app install method but as i suspected, it said root is required for this app and promptly exited so i shall do the odin method, i heard that some people remove root or it could be that it was done wrong. also after reading a few posts here and there i found out that someone had similar issues with their phone random re-booting and they had custom ge with the wrong kernel so it seems once im done my issues should be history if i learn how to install fw + kernel, after this twrp thing i will be one step closer for sure. i also know ppl slate lollipop but once im all done with this im sure i will have picked up enough terminology to install cfw's to my hearts content. hooray for forums and people like you, sounds like im kissin ass but its just gratitude
so using the twrp install guide i gotta install using the odin method i have now got 3.07 odin but this is the next step.........
Odin Install Method (No Root Required):
You will need to download and install Odin on your PC. Once you have Odin installed, download the proper .tar file for your device from the download link above. Power off your device. Turn on your device using the proper key combo to get into download mode and attach the device to your computer via a USB cable. Use the PDA tab or button to browse to and select the tar file that you downloaded and flash the device.
lololol nothins ever simple i see the list of tar files in the link above but no mention at all as to which is the proper .tar for my device, i guess they assume the guide is for people who have done it before. more research tomorrow maybe i gotta be up early ugh

Think you misunderstood, I have flashed nothing yet I got it like this. I'm completely green
Don't suppose anybody knows which is the tar file for my device?? S4gt-19505
OK now I get it, the list of tars in that section are all the same just newer builds of the same version. Seems obvious if you have done this before, but I wasn't to know that and cannot assume things. I'm also gonna guess and say Lenny thinks my s4 needs this particular version for an international, am I right?? Anyway it would've made a lot of sense but how does he know. I have no idea what this phone was I have never owned it new.
Different devices have different codes. For example, jfltexx is the I9505. A T-Mobile S4 would be jfltetmo, and so on.The link Lenny provided is for the I9505. Download the 2.8.6.0 version as its the latest.
As to how you were supposed to know, having never owned one, you weren't. There are tutorials in the General forum though that can help.

[Q] Accidentally killed stock recovery

Hello everyone! I'm brand new to the forums so if I am breaking any rule or regulation, just give me a heads up. So, some basic information about my predicament.
- own a Samsung Galaxy Note 3 from Verizon.
- I use t-mobile network. Works great with no problems.
- phone was successfully rooted via towel root.
I was looking to get cynagenmod on the phone so I started looking up guides and such. Only thing I wasn't aware of was that carrier branded versions can't have their recovery flashed. That said, I used flashify and the clockwork apk. The app did its job, killed the stock recovery, but couldn't load the new one. Now the phone says error, no recovery when trying to access it during boot.
It should be said that the phone still boots and works normally but I really want to get the recovery working so I can at least try again the right way to get cynagenmod working.
My question is, is it possible to get my hands on the stock recovery for my phone and just flash it back to how it was? Basically, how do I fix this problem I put myself in. Of course, I didn't make backups. During the whole process, I figured "if I follow this tutorial word for word, why bother with backups?" look how wrong I was
Any help would be sincerely appreciated. I'm posting this from my replacement phone, not my note 3.

How to upload LineageOS to i337 with locked bootloader I337UCSGOK3 and other things..

Hello to all forum members. :highfive:
Recently I got into my hands the Samsung S4 SGH-I337 version of AT&T, at least I think so. The current version of Android on it is 5.0.1.
When I set the phone to recovery mode, I think I see the modem version: I337UCSGOK3. Correct me if this is not the modem version, but I am sharing it because I guess this information will be helpful to make alternative software installation.
I've already spent 7 days trying to change the software, reading one by one what I will find about such an update. I tried tons of instructions and they all didn't let me do upload/change somehow software nor even install TWRP.
Tried to upload TWRP (I think I found 6 different files) using different applications from the original Android system - Failed. ie. I used TWRP straight from the system, I also used Flashify. When I use this Flashify app I installed TWRP, but it didn't let my phone go into recovery mode, it just went straight to the download. For me it looks like there is something to not let flash/change this to TWRP.
I tried to upload TWRP via ODIN, it doesn't work, it crashes during installation with error messages.
I also tried to upload lineageos version lineageos.17.1.recovery.img via the normal recovery mode, but every time I try I get an error about the signature not matching.
I tried to upload the software by ADB, I have had connection, I was able to see the phone, but I can only use adb sideload recover.img command and although I tried different images and .zip files, unfortunately nothing works. I think I also get an error that the signature does not match.
Can I ask you for some hints, maybe some instructions that will really work. Many instructions were based on specific versions of the bootloader, is what I called the modem above maybe I named this wrong and this is the bootloader version? If so, does anyone know about the instructions for this version of the bootloader? It seems to me after my problems that it is strangely blocked. Maybe someone knows how to make it work. I would like to change the software to change the system language to Polish. Unfortunately, the apps: MoreLocale2 and Language Enabler and probably about 4 others from the play store are not working.
Of course, the phone is rooted with Kingoroot, the applications detect that there is root, after all, after selecting the Polish language, it does not work in the system.
I would like to change Androind 5.x to LineageOS, because there you can do much more and it works better, more efficiently and saves battery. And I will be able to change language defenetly.
this is not the first time when I do that things. I have changed the regular S4 jfltexx many times, this is not the slightest problem for me.
Summarizing:
1. I would like to change the language to Polish, if it doesn't work or it won't be possible, it's a waste of time or something else
2. I would like to unlock the bootloader and upload TWRP, it can be CWM if anyone knows it will work and has an instruction that I can test
3. Then I would like to upload lineageos.
I'd appreciate any hints to test these things above.

https://forum.xda-developers.com/showpost.php?p=81418691&postcount=29
I read that it will be possible to upload TWRP, but if it is a special version of TWRP prepared for this phone. Will someone be so nice and tell me if something like this exists and if so, where can I find such TWRP for uploading via ODIN.
Thank yo all for your time spending to read this.:good:
PS: Dear Moderators if this thread is not in proper place please correct this. Thank you.
Those instructions are for another bootloader. Your bootloader is locked, which is why TWRP won't install. There is no way to unlock it or downgrade. You also can't boot AOSP based ROM like Lineage OS. What you can do is root the phone and install touch wiz based ROM like Golden eye ROM by using the flash fire app if you're on lollipop or safe strap recovery if you're on kit kat.

Big Thank You for your suggestion and answer on my question.:good:
Right now I have Lolipop installed on the phone so related to this above I can only install something with touchwiz. Hope it will let me to change language to the Polish.
Would you be able to point me some links to instruction, please. I try to find this on forum but failed (getting ROM for nintendo). At least links to the software so I can try using flashfire app. The best it will be instruction, as I have situation in which when I use this app phone want boot after. Maybe it was related to the software, which I shouldn't use or maybe I do this in not proper way.
For everything what I get I'm saying thank you. :highfive:
No problem, I help when I can. The flash fire app you can get from the Google play store I believe, but your phone might need a specific version like the Verizon S4 does I don't know. The touch wiz ROMs are in this forum under Android development, go there and you should see ROMs like golden eye which is a touch wiz based ROM.
Here's a link that might help you, but the S4 is an old phone so it's hard to find links and guides that aren't buried deep in the forum posts.

Let me check this and back with the details what is working.
Alright man, good luck! I may not be able to help much further though, as I now have a Galaxy S10 and my S4 is just my storage phone, but I can try if it's something I know.
