[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] thekingof7:
Greetings Everyone,

I recently acquired a Samsung Galaxy S5 SM-G900R6. From what I gleaned from the original owner, the phone was purchased through a small provider in northern Wisconsin called cellcom. Cellcom has no interest in providing any support for the phone or confirming its lock/unlock state. I would like to get it working as stock with Tmobile, U.S. Cellular or Verizon.

Currently the phone will accept any sim card I install but shows no network. Interestingly, when using a U.S. cellular SIM, the phone finds the network and refers you to a collect call service when a number is dialed. Would this imply that the phone is unlocked? Or is this an issue of APN settings?

The current firmware does not support any of the dial codes and does not allow switching to GSM (only shows CDMA/LTE options) in the APN menu.

I have tried to follow this thread, but it is full of custom rom jargon that goes over my head. My hope is not to run a modded rom, but rather, a stock rom.

In short: From what I've described, does this phone sound SIM locked? Has anyone narrowed down a good procedure for flashing this to a stock rom from a different carrier with success? Last, if I flash this phone to a stock carrier rom, will it continue to function as such or will it need constant community-sourced updates? I was hoping to gift this to a non-tech savvy family member.

[MENTION=5438911]evilryry[/MENTION] what would be causing this error?

http://i1060.photobucket.com/albums/t441/XPGTool/2015-03-26 20.52.08_zpsytzm7nzl.png

Here is what I did:

1. flashed Android 5.0 with odin 3.09

2. flashed twrp with odin

3. flashed ktoonsez twrp in recovery

4. flashed ktoonsez kernal in recovery

5. flashed supersu in recovery

6. verified root with rootchecker
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Something with security on stock I think. Have you ever thought about using a non stock rom? [MENTION=4354794]fantasy2c[/MENTION] ever seen? Try to disable knox with supersu
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
[MENTION=5438911]evilryry[/MENTION] i dont see the option to disable knox in supersu pro. supersu doesn't ask me to disable knox anymore.

I would try a non stock rom if I could find a easy one with instructions.

Can you link me to a couple good ones & tell me what I need to do for each?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
I would run a non stock rom, like evilryry said, it's probably a security issue, I've never seen it but I've never ran a completely stock rom on lp either.

Either because of root or the ktoonsez kernel
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
[MENTION=5438911]evilryry[/MENTION] [MENTION=4354794]fantasy2c[/MENTION]i just used terminal emulator to disable knox and will see how it goes.

What roms are the best for someone that is new to roms on the s5.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
I'm running xtresolite lp from the international forums with some patches everything works. A cool verizon one is alliance, battery life is ok but the customizations are nuts. So many things you can do on it. It's a pretty cool rom if you like different theme options. Moar is alright as well. All personal preferable really
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
just looking for a good basic rom, not interested in all the bells & whistles.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
tested 5.0 alone today and no issues, going to try to add 1 thing at a time to see whats causing the issue.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Kernel. It's because of knox. It'd gonna be like that on stock unless you remove it or try another rom
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] gotmiller420:
I'm also using a Bluegrass Cellular Galaxy S5 and am trying to unlock it so that I can use it with Straight Talk. I have backed it up using TWRP. If I use the Qualcomm Recovery, will I be able to use Straight Talk or can you give me any insight on how to? BTW, my girlfriend really wants to use AT&T, but I was told it requires GSM around here and I wouldn't even know where to begin. Any advice?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
I'm not sure if you can. The r6 and some other lra model phones don't have gsm radios, because the lra carriers don't utilize it. So all you would get is LTE with straight talk no talk or text. You might be able to get a straight talk cdma activation kit and set APN's though. Not sure.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] gotmiller420:
I already have a cdma activation kit from straight talk. It's a byop kit, but Bluegrass cellular locks their phones and it will not recognize the sim or let me activate the phone. I seem to have screwed up my phone since my last post too. I made a backup using twrp manager. I tried flashing a custom rom. It didn't work. I rebooted into recovery mode and restored using the backup i made. Once I rebooted, I got a black screen with a bunch of pop ups telling me that unfortunately, services had stopped. What should i do?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Odin back to stock or factory reset then restore everything but data. What custom rom did you try anyway.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
[MENTION=5438911]evilryry[/MENTION] is there anything i need to backup before trying a rom (apn or imei)? If so how do I do it??
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Apn. Use apn backup and restore, follow directions from this link. http://xdaforums.com/showthread.php?t=2656046

Imei is in efs, twrp backs that up by default but don't worry, rom flashing doesn't touch that.

What rom were you gonna try?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
no idea what rom i'm going to try, i was just going to start at the top and work my way down in the forum.

any suggestions on what to try first?

Update: Can't backup apn in 5.0, pic below.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
Either change apn backup to a system app then move to system/priv-app or download the apk, use a file Explorer to move it to system/priv-app set correct permissions and reboot and it should work
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
you either didnt make it a priv-app or didnt uncheck disable ics check in settings of the app
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
got it working & backup made.

now to decide what to test..
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
I have tried a couple roms and can't get them working, could someone that has tested roms on this device please list a couple good roms that work.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
[MENTION=5438911]evilryry[/MENTION] & [MENTION=4354794]fantasy2c[/MENTION] if I flash the OptimalRom do I need to backup anything other than APN? Also after I install the Rom is there anything I need to install?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
You need the stock rooms apns, and after u flash optimalrom u need Galaxy tools to change sales code and something else to LRA, you need a root Explorer (I use es file explorer) set to use root then go to root directory, system, etc, csc and Change the sales code to lra, load your apns and reboot.

Takes 10 to 20 min to boot the first time, phone will get quite warm, I put mine in the freezer just because I'm weird like that
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
I could give him the patch to flash after the rom to fix the csc things so all he would need would be the apn change. Flash this after the rom. Only use it on optimal rom

[MENTION=5438911]evilryry[/MENTION] & [MENTION=4354794]fantasy2c[/MENTION] Could one of you list the proper steps to flash if already on 0B3 5.0? All I see is VZW flashing instructions about flashing a kernel and booting to safestrap.

Thank you both for the help & files!!
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
I always recommend a clean flash less chance of things getting screwy
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
[MENTION=4354794]fantasy2c[/MENTION] all I see is vzw flashing instructions, since I'm on 5.0 already do I just clean flash the full package, flash the Lra zip, restore apn? Since I'm not using safesterap? Do I need to flash the kernel it mentions?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
Download or, reboot to recovery, use twrp, if u don't have a backup I highly suggest u make one, hit wipe, hit advanced wipe, select dalvic, cache, system, data nothing else. Swipe right. Once cleared go to install, go to where u put or zip file, select it and flash.

After that's finished flash the zip evilryry posted, now u can boot up or you can flash ktoonsez kernel then boot up. Once it loads, it'll be 10 to 20 minutes setup apn backup restore, delete apns then restore those you saved from your stock rom and enjoy the rom.

Verizon s5 is slightly different most have locked bootloader we don't so they are way more limited in what they can do opposed to us
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
[MENTION=4354794]fantasy2c[/MENTION] is it supposed to stick on the Samsung Galaxy S5 boot screen and say Set Warranty Bit: kernel, is that where it sits for 10-20min?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
No it should only be there for like 5 seconds then go to a Samsung logo

How did u flash it?

If using ktoonsez kernel you used the tw one for 5.0 right?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
[MENTION=4354794]fantasy2c[/MENTION] I was watching the install and it said something about no kernel installed that if it was a dev edition to install the appropriate kernel. Do I need to install the ktoonz kernel before the rom??
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
Flash rom, evilryry's zip, then ktoonsez tw 5.0 kernel...
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
[MENTION=4354794]fantasy2c[/MENTION] I did that exact steps after the wipe and it got stuck on Sam Galaxy S5 screen. I'll retry it.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
How long did u wait
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:

[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Did you backup and wipe before flashing

Maybe you got a bad download, re-download and make sure the rom is on internal storage..
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Morinzo I don't think anything was wrong with the patch I gave you but just in case here's another to try, remember, wipe, flash rom+my patch+ktoonsez kernel tw 5.0 and that should be all that's necessary. https://www.dropbox.com/s/7c7ht6swrn0tfv8/LRA_Lollipop_5.0_vzw_patch_v2.zip?dl=0

Do you mean the stock rom that was posted earlier in the thread?

---------- Post added at 03:36 PM ---------- Previous post was at 03:11 PM ----------

Let me rephrase my question.. I am considering rooting my phone. And I would like the ability to still get updates and maybe even flash custom roms eventually.. But with my old HTC phone I never could get the MMS to work after words. Are you telling me that if I use the stock rom that was linked, MMS and Data will work just fine without any modifications?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] alexander7567:
Also is it possible to unroot? I know most people can just use a flash program and reset everything.. But how do you get a Bluegrass Cellular flash file?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
After I redownloaded everything I got it working!!! So far it's alot faster and smoother, I have verified calls, 3g, 4g lte, txt working on it so far.

I was going to use the same sd card to do my other 900r6, would the APN backup be the same for it? Same model & carrier?

Will give post thanks when I get home..
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Flash file is the same for each carrier that uses this model. Can get the firmware on sammobile. Build OB3 is lollipop

Sent from my Supercharged KT Powered S5
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Apn backup is tied to the carrier so as long as your other r6 is on the same carrier which I assume it would be then yes it'll work.

[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] alexander7567:
So let me ask this then... If I was to root my phone, install custom software, etc, then in theory I could:

1. Backup APNs

2. Follow these steps to unroot: http://www.w0lfdroid.com/2013/04/how-to-unroot-samsung-galaxy-devices.html

3. Restore APNs

4. And I am completely unrooted, back to stock.. Done. Warranty is back and everything? Able to install OTA updates etc?

The main thing I have a question about is that when I tried to use APN backup and restore it said it was unable because of my version of android. So someone suggested online to make it a sys app.. But how can you do that after you flash it and lose root?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
MMS is working on optimal rom, I have just tested calling, receiving calls, 3g, 4G lte,txt & mms

Just be sure to go 2-3 pages back to where evilryry explained how to backup your APN & be sure you do it before you flash optimal rom.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Flashing firmware back to stock removes root too. Can only get ota if you don't trip knox (custom kernel/recovery) even if you flash back knox is still tripped. But the latest firmware is always available to you on that site. U use apn backup and restore as a system priv app. Why do you not want root??

Sent from my Supercharged KT Powered S5
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] alexander7567:
I do want root, but If I ever need to revert back then I would like to have the ability to. I guess I just had so many problems with my last phone after I messed with it I am scared to with this phone! So is it possible to not trip knox?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] Morinzo:
I have tested alot of stuff and had TW not load & had the phone not but but It's easy to Odin back to stock.

[MENTION=5438911]evilryry[/MENTION] Is there any other rom I should test that is better than Optimal??

I tried to give thanks to [MENTION=5438911]evilryry[/MENTION] & [MENTION=4354794]fantasy2c[/MENTION] for all the help & I'm limited to 8 thanks per day, lol..
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Only if you don't use a custom kernel or recovery. It's easy to flash back to stock but knox is forever tripped... Only matters if it's under warranty for any sort of hardware problem. I tripped knox the first night I had this phone. I personally don't give 2 craps about knox. Firmware to flash stock rom is always available only thing is you can't accept ota's but you can just manually flash the newest update once it's available....

Hey so I know I'm doing something wrong.. I just can't figure out what. I go to his page and download the twrp for s5. Use flashify to flash it. After it flashes (takes half a second) it says flash more or reboot. I hit reboot to see the twrp and I get just the basic recovery. So I hit reboot and after the Samsung picture loads I get a black screen and one by one all the apps crash. And the only way I have found to fix it is do a factory reset. Any ideas?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Use twrp manager app to install the normal twrp then when in it flash the ktoonsez twrp recovery to replace the stock twrp. Stock twrp isn't that good but it'll get you to where you need to be

Cool.. that worked. I was afraid to try cause I couldn't find proof that anyone has already tried it and it did not mess up their phone! So before I start flashing OSes, I am having a problem with APN backup and restore. I have made it a system app. I can back it up as expected, but when I go to restore it, I get the following message:
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Well that's how I did it the first time and it didn't screw up my phone so, lol. As far as apn backup and restore goes, Use a root Explorer to locate the apk in /system/app (you'll see the icon and it'll be named named something odd starting with com) and hit move on it, paste it to /system/priv-app reboot and it'll work.

[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] GF Geek:
I just got a TMob S5 (SM-G900T) on Android 4.4.2 with Build NH5. It's rooted with the CF Auto Root and I want to flash the KT TWRP Recovery.

So here's what I understand from your post:

1-Install TWRP Manager App

2-Use the TWRP Manager App to install stock TWRP

3-Boot into Recovery (Hopefully TWRP at this point) - Use the stock TWRP Recovery to flash the Ktoonsez TWRP recovery

IS THIS CORRECT? :confused:

BTW-Flashify wants an img file for flashing recovery. The KT-TWRP file I have is a zip file. How do I use Flashify with a zip Recovery (the KT TWRP)???
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] alexander7567:
The only reason I had to do stock first was cause I was having problems doing it that way. If you can flash without doing stock first, do it how it was described a few posts up. you must first unzip the zip file to flash.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] GF Geek:
The KT TWRP zip contains a recovery.img file PLUS an update-script and an update-binary file. So if I unzip the zip file and use Flashify, do I just flash the recovery.img?

What happens to the other files?

BTW-THANKS for the prompt response!
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] alexander7567:
Well I haven't did much flashing but I think all u need is the img file. The other are to flash via recovery if you already have it installed.

Has anyone tried cyanogenmod and got it working succesfully? I have always liked it, but I can find a 12.1 version that's made for vzw. Anyone had any luck?
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] evilryry:
Me and fantasy2c did. It works ok. Will need apn backed up. Also keep in mind that mms won't work without using 8sms. We don't have s5's anymore so this is the newest build that will be flashable on the r6. Normal vzw ones won't flash on it because of a difference in the system partition size so it had to be decompressed. Build date 5/27, keep in mind it's not perfect. Don't expect support from the official cm thread, or here really, sorry. Remember to also flash latest g apps. When it boots up go in dialer and do #*#*4636*#*# and toggle network mode to LTE/cdma. It will be on LTE gsm at boot and may flip back a few times before it sticks. After you get it to stick, you won't have to do it again.

[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
Cm.. Just for the fact anything else floods with *alarm* wakelocks n messes with the battery life quite badly. U can try anything that doesn't use odd format like fusion was old style format before but can't say how good it'll run bc in my experience everything besides cm evilryry and I tried had that issue. Every aosp style rom will need fixes like evilryry said above.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] alexander7567:
Where did you guys get the cm rom from if it's 12.1 vzw? Cause the official site it's only up to 11 and there isn't even an rc for that. And how did you fix the partition? I would be more than happy to carry on the updates if I'm taught how.
[Verizon Galaxy S 5 Q&A, Help & Troubleshooting] fantasy2c:
Know someone that makes them and get them from him. To make all the aosp style roms work you need to be familiar with Ubuntu to decompress the files. I don't know how to do it but there are guides online
