[Q] Credo (Sprint) GS4 (Rooted) - Won't Boot - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I've got a Credo GS4 (SPH-L720T). Probably stupidly, in Titanium Backup, I made a backup then uninstalled Samsung Hub along with other Samsung bloat. After this, screen rotation wouldn't work. I reinstalled it in TB using the backup. Rotation still didn't work. Sensor functions in games and *#0*#. I found a post indicating I should put a file with a .so extension in the system folder. After this, it hangs on the Samsung portion of the boot (just after (Samsung Galaxy S4 flashes initially). I've given it 15 minutes.
I can't get it into safe mode. It will go into recovery. I attempted to find a Sprint stock ROM and couldn't install it ("Header is wrong") about 30 seconds in, more lines of text I couldn't read because they scrolled fast, then a reboot.
So, can I get at a stock .zip for Credo or Sprint (APNs are supposedly the only difference), or can someone recommend a 4.4.2 ROM for the triband version that supports resizeable multi-window?
If someone's reasonably local (I live in Walnut Creek, CA, and work in Hercules), I'm happy to pay consulting time.

[Q] Screwed up my Galaxy tab, need stock Tmo odin files

So I have a Tmobile Galaxy Tab, and I ****ed it up somehow.
I tried to put clockworkmod on there, and somehow it gives me a black screen every other option, so clockworkmod only shows half the time. But it still works.
Tried to revert to factory via the settings menu, it didn't work. Tried to do it ia clockwork, it didn't work. Tried a few more times and somehow I got it to work, but almost everything that was stock is not here....I"m stuck with nothing but android and some tmobile addons, vending.apk ain't even there.
So, I"m throwing in the towel and would like to know if anyone knows where the stock files for the tab can be found. I looked on the wiki, and it tells you to make a backup before everything is ****ed.
:|
Yep,
As the wiki says there are no recorded firmwares of stock US/Canada tabs for the most part.
If I were you though I'd simply flash JM6 and then JMC ontop of it.
You'll lose all your stuff but your tab will be better off anyways. Performance of the dev firmwares outdoes any of the stock ones. And you'll get a few extra features while you're at it.

AT&T Now Bricks Modded Galaxy Tabs

What used to be a simple patch to permit AT&T Galaxy Tabs to download apps from sites other than the Google Market is no more. We recently got our Tab back from the Samsung repair facility and it was wiped clean and loaded with a new Android version that now puts your Tab in an endless boot loop if you attempt to patch the config setup to permit downloads from outside Google Market.
Simple solution: DON'T BUY AT&T-BRANDED GALAXY TABS.
If there were some sort of unlimited data plan, this kind of behavior might be warranted but since AT&T charges by the amount of data you consume, there's really no excuse for crippling these devices... other than just being assholes!
Not entirely sure what you're referring to here. I have an AT&T SGT and it works just fine with sideloaded apps.
Did you run SuperOneClick root and then enable non-market apps?
Either way, nuke that horrid stock ROM with one of the Euro roms and you'll never have to worry about AT&T's crippled version again.
Yeah, but...
There still are a number of ways to root the phone, but the new checksummed firmware will make it extremely difficult to load custom roms with any hope of restoring an earlier firmware version. And, once you update your current version of Android, using the standard method of allowing non-market apps by changing the non-market apps entry in /dbdata/databases/com.android.providers.settings/settings.db will put the device into an endless boot loop when you restart it.
So, while it used to be simple, those days are over. No need to shoot the messenger.
What version of firmware did your Tab come back with?
What method did you attempt to enable side loading?
I find this very hard to believe because every single ATT Android device to date has been able to side load after a simple 1 bit edit of the device settings db.
I believe that you had problems with the SuperOneClick app but there is a much cleaner / safer way to do it.

I don't believe my ATT SGT came with a protected bootloader, and if I'm not mistaken, AT&T hasn't released any firmware updates via KIES or OTA. So while there's always the possibility of Samsung "screwing" us all with that mess, it's only been seen on the leaked firmwares. Not that I don't put it past the big blue DeathStar to opt to use something like that to prevent people from avoiding their preloaded garbage....
I'm happy I liberated my device from the clutches of the Evil Empire, and will gladly look to XDA for my future upgrade paths.
Could just be a bad software flash from factory. A number of t-mobile vibrants couldn't get to restore via volume up/down power because of a buggy flash file they put on a certain build date

Virgin Mobile Galaxy s5 "Post here" of your ideas/learned

Please post here ALL of what you learned/thoughts/ideas. My goal is to get the Sprint based phone "G900P.04" Virgin Mobile users up and going.
I am not responsible for ANYTHING!!! Try doodling with your phone at your own risk!
THIS IS WHAT I GOT SO FAR:
APN SETTINGS:
Virgin Mobile Samsung Galaxy s5 as all the capabilities of flashing any Sprint based G900P.04 ROM/Tweak. However, once flashed, you will have Sprint based network APN settings/not virgin mobile network APN settings. APN settings is what allows you to call/text/LTE/send receive text/pictures. Currently the Virgin Mobile stock ROM doesn't have the option to manually set APN settings though settings/network connections/more networks. However, once flashed to a Sprint ROM, this option "should" now be available to edit. If ballzy enough to try flashing a Sprint ROM and obtain data capability PLEASE POST YOUR FINDINGS. Virgin Moible APN settings can be found at this address:
Virgin Mobile USA APN Settings
I called Virgin Mobile and told them that my send recieve text doesn't work and ask if i can access APN settings manually to check if there correct. He gave no option to view them manually. He advised to dial ##72786# which he said redoes the hands free activation process and "?may?" fix the APN issue.
Apps like the APN backup & restore is another option "if exhausting all other available options" a thread I found HERE It appears that if you know what your doing, the app will work but nevertheless, people has reported it not restoring APN settings.
ROOTING Virgin Mobile Galaxy s5 Obtain warranty without tripping knox counter:
The CF autoroot though odin I seen threads that it trips the knox counter but the "towelroot" method doesnt trip the knox counter and was easy for me.
How to:
1. Go to settings/system/security/allow 3rd party apps. As long as you know what you download I disabled "verify apps" while I'm their.
2. With your phone, Download towelroot HERE and click the red logo to start download
3. Download a file explore application from Google Play "my favorite is FX File Explorer/has secondary Playstore download for accessing root files" and install the tr-1 .apk you downloaded.
4. Read and click the option to root phone.
5. When it says remove knox I clicked "yes."
6. As mine did also, a lot of users report that the phone didn't complete/auto reset device but hung on the "removing knox process." Personally I waited 5min---pressed the home button---manually reset phone.
7. Go to Play store and download/install SuperSU---update binary's---reset phone
8.Your phone is rooted/complete.
Return to Factory Stock
Reflash the phone with the factory stock ROM with Odin can see instructions HERE
Note: Virgin Mobile users only has the option of the Sprint ROM so im curious if this will bork up APN settings...putting them on Sprint/not Virgin Mobile settings. The hand free activation by dialing ##72786# may/may not work.
Custom Recovery:
All Sprint based recoveries I'm positive will work. Custom Recovery opens up any theme/tweak/ROM capability. However, im reluctant to do so because you will not have the ability to update the OS when it arrives because it requires the stock recovery....where you have to do the Return to Factory Stock option just posted.
I've always used Philz Touch Recovery and was always happy with it. Insturctions HERE
There is a TWRP recovery but even people on the TWRP thread say that they hear good things about Philz Recovery.
Installing a ROM:
As mentioned, only Sprint Based ROMs work because it's a Sprint phone. However, if flashing a Sprint ROM through your custom recovery it should error. This is because the developer Puts a script in the ROM that only allows Sprint not Virgin mobile phones to flash the ROM. To fix this, it requires editing the ROM with NotePad++ and deleting the first few lines of code. Good thread to read how to do this is HERE
Apps/Tweaks:
Im still using stock ROM up until somebody with experience can guarantee I can start flashing ROMs without any mishapps.
..Adaway is working great.
Link HERE Couldn't beileve the amount of ad's is on the Internet...even on XDA. Just open/install with a file explorer like FX File Explorer...make sure under settings/security you check "Unknown sources" so you can install apps outside of play store
Wanam Xposed is amazing
Verified working on my Virgin Mobile Stock ROM. Install Wanam from Playstore and install frame work from HERE Now got my phone all theme'd blacked-out like how I like it. 4-way boot menu working too. NOTE: Wanam website states S-Health conflicts with it...so recommend uninstalling it.
Native Hotspot Enabled:
Install this App HERE GalaxyTools.apk. Click Enable Native Hotspot and reboot phone. "Mine rebooted automatically once enabled." Now I access my Hotspot using a playstore hotspot widget "my perfered is called Elixir 2 from the playstore. " on my home screen.
Debloat Stock ROM:
App Master is small and can go to system files and debloat all dumb apps Samsung/Virgin Mobile put on there. A thread HERE shows what Apps are safe to remove.
PLEASE POST ALL YOUR FINDINGS/THOUGHTS/IDEAS
Rather than restoring a Virgin Mobile phone to a Sprint stock firmware we can use these firmwares instead
G900PVPU1ANE5 STOCK VIRGIN MOBILE
G900PVPU1ANK4 STOCK VIRGIN MOBILE
G900PVPU1BOA6 STOCK VIRGIN MOBILE
G900PVPU2BOD3 STOCK VIRGIN MOBILE
G900PVPU3BOF6 STOCK VIRGIN MOBILE
G900PVPU3BOG1 STOCK VIRGIN MOBILE
Notice the Product Code is VMU, which is for VIRGIN MOBILE!
I'll try to keep this post updated with Virgin Mobile Firmwares in case more are added, for convenience and reference
Here is where I got them from
FIRMWARES | SAMMOBILE | VMU
VM's stock ROMs are on sammobile.
Working are CF auto-root, and Philz recovery (via ODIN).
The latest Sprint NK4 ROM (4.4.4) can be ODIN flashed on top of the VM stuff, and everything keeps working as VM. (Towelroot does not work on 4.4.4.)
I don't believe the VM APN settings posted above are accurate for this phone. But if you do the above (CF auto-root, Philz, Sprint ROM), you should be able to get to them on your own phone.
Presumably there will be a stock VM 4.4.4 ROM released soon regardless.
I don't know that there's a need to do much VM-specific stuff separate from what's done for Sprint.
I've been having two flashable zips that I use when switching to a new AOSP based rom (like CM, PAC, whatever), so rather than doing it manually, for you lazy folk like me, you can boot into Recovery, after having checked that you properly flashed your ROM, and flash these VMU APNs. This is for KK ROMs only! If you flash the file named AOSP_MMS_FIX.zip on lollipop you will get a Bootloop.
I got them a while ago so I forgot where or who made them, if you are reading this however, let me know so that I can give cred
By the way, does anybody know how to get MMS working on lollipop? With lollipop roms I can flash the file Universal_vmu_ApnFix-v.R2.zip to get texting and calls working but it doesnt fix picture messages.
EDIT: The Universal_vmuApnFix-v.R2.zip DOES work on AOSP lollipop roms. Just do not flash the other file.
The Sprint Lollipop 5.0 OA6 stock tar posted at the following does also appear to work for VM. Somehow it does know it's on a VM phone -- VM boot logo and everything:
http://forum.xda-developers.com/showpost.php?p=58662929&postcount=1
No problems with the latest CF Auto-root in that thread. Philz 6.57.8 appears to still work after renewed flashing, too.

d99x, no APN fix was needed when you flashed that Sprint OA6 onto the VM S5?

Correct. And though APN settings are no longer accessible via "More networks," an S-Finder search for "Access Point Names" still turns up the settings. Confirmed to be VM. Everything's hunky dory automatically. :good:
For what it's worth, I backed everything up via Kies in advance. After all apps re-downloaded from the Play store, a Kies restore did get back most if not all of my settings. It just can't restore apps themselves to the new build.

Whats Knox like on this phone coming from the s3, if i trip knox once while rooting, how does that affect me when I want to flash a custom rom?
i just got my virgin mobile galaxy s5. i have yet to root and want to understand this fully before i do what i would like to do as ive had experience with bricked devices and dont want a repeat of the feeling. i want a to make a list of what i think i should do and i would love it if i could get corrections on anything thats wron with my process. i and on the sm-g900p model for VM. baseband: g900pvpuboa6 and android version 5.0 lollipop.
1. (while in download mode) connect s5 to computer
2. open odin 3.9 or 3.7
3. select pda/ap and place CF Auto Root into the slot and let it run until the bar turn bluor green or whatever color means that its good to go.
4. apply a custom recovery (i personaly like PhilZ touch recovery)(i am not sure exactly how to do this. on my s3 i was able to apply the recovery via the stock recovery but i dont know if that is possible with knox and all)
5. go into custom recovery on phone and apply the latest version of supersu
6. in custom recovery apply and deknoxify and debloat zips
7. boot up phone and update supersu and run a root checker
8. do whatever with your new rooted s5
i would love it if someone could tell me if this is a tested method or if i am missing something or doing something wrong. any help would be much appreciated as i really dont want anything to go wrong. i also would love it if someone had a link to philz touch recovery that is properly compatible with my version of s5 (sm-g900p VM)
It's not critical, but the latest ODIN is 3.10.6:
http://forum.xda-developers.com/showthread.php?t=2711451
PhilZ is at the following. You can flash the latest 6.57.8 tar.md5 the same way in ODIN. Remember he's no longer developing or supporting this, but it works for now.
https://goo.im/devs/philz_touch/CWM_Advanced_Edition/klte/
You do not need to flash SuperSU via a custom recovery if you don't want to. You can add/update it just fine via the Play store.
You do not need to apply the de-knoxify and debloat zips if you don't want to. If you want, there are other file manager programs out there that you can also use to "freeze" Knox (if it makes you feel better for some reason), and to debloat manually yourself.
If you mess up badly, you can use ODIN to flash the full restore TAR from the following (extract it first). Though it's in a "Sprint" folder there, it recognizes it's on the VM variant of the Sprint phone just fine.

thank you. the philz recovery i was using was too outdated and caused me some problems. and cf auto didnt seem to want to work. however the recovery you gave the link to worked flawlessly and allowed me to flash the supersu update and gain root.
my next question is weather or not it is safe to flash a sprint stock android L rom and keep my calling, text and mms, and 4g data seeing as i am on VM and not sprint (i do know they are the same phone internally but coming from a VM s3 i needed to flash a APN fix everytime i flashed a new rom to keep things working)

I read somwhere that this may be the case this time around aswell, dont know 100% though
The Sprint stock ROM recognizes it's on a VM phone just fine. What's been issued is identical. On a VM phone, it sets up everything for VM -- boot animation, APN settings, everything. There is no need to flash an APN fix or alter any settings to adapt it to VM. That's why when people have tried to start Virgin Mobile threads here, there's been little to no response. There's virtually no need to do anything unique to VM when it comes to the S5. What works for the contract Sprint, works for the pay-as-you-go Sprint, aka VM.
I have not tested non-Stock ROMS, and don't know what you may run into if you start experimenting with custom Sprint ROMs on the VM phone.
If you want to alter your APN settings (though there should be no need on the stock ROM), you can search "Access Point Names" in S-Finder in the drop down menu once the ROM is installed.

I would think that if you were to flash Cm 12 you would have to follow it up with some sort of apn fix

thats more so what i meant. ive realized through a little research that using a sprint rom on my vm in fine. i believe this is so because unlike most other VM phones (such as my previous Galaxy S3 VM) the Galaxy S5 uses a VM sim card. something that i found unusual but suspect is the reason for never haveing to change anything ( please coeect me if you know im wrong on this information because right now im working with this as a hypothesis). however i dont know what will happen when i install CM12, which is something i want to try out. my VM S5 doesnt have a Data Toggle in the notification tray which annoys me to no extent. i cant seem to find a way to fix this nor can i find in the stock lollipop rom that the phone comes with. ive always loved stock lollipop and ran CM12 on my S3 but the community for it on Android Forums was huge as still is, so finding how to change the APNs on the VM locked S3 was easy. this isnt the case with the S5 neither there nor here at XDA. i either want to fix my data toggle on my stock rom so i can keep my fingerprint scanner (which for me works more times than not) or switch to CM12. i dont know which is the better option as far as keeping everything working.

Have you tried MOAR v6.0

PLEASE HELP!! Samsung Galaxy S4 i337m Fido cannot make phone calls!

Hello, I hope you can help me with my problem.
I am using a Galaxy S4 i337m Canadian Version locked down to Fido. I was trying to install Google Play Edition 4.4.4 from here: http://forum.xda-developers.com/showthread.php?t=2537495. I installed TWRP, did a full wipe, and then flashed the GPE zip. It rebooted, most things seemed to be working, except it showed 'No service', and could not make any calls. It would start to call, then the screen would go black and it would lock up. I went back to a stock rom, but was still getting the same problem.
Now Data is working, and wifi, but cannot make calls. I have checked the APN and all checks out. I flashed the modem.bin file proper for my device via TWRP, I tried via Odin, but it fails in Odin.
I did 2 previous ones for family members, exact same phone, same carrier, with no problems. I don't know why this one is doing this. I have backed up and restored efs with EFS Professional, did not help. Please, please any suggestions.
Thank You.
Edit: I have also left the battery and sim out of the phone for 2 hours to no avail.
Edit: I have tried 5 different 4.4.2 stock roms, all have the same outcome. Cannot make calls, trying to fails and makes the phone lag out. Wifi and data are working, IM sort of works. It says it cannot send, but then 10 mins later the recipient gets it. Still cannot flash modem.bin files in Odin, install goes to the end, then says Fail all in red. I can install successfully the .zip via TWRP though, but it changes nothing. Have tried a few different Canadian modems.
Fixed: Installed stock firmware: I337MVLUFNE1_I337MOYAFNE2_I337MVLUFNE1_HOME.tar, and everything came up as normal. Wiped, flashed Google Play Edition 4.4.4, working flawlessly. Note: Firmware I337MVLUFNC1_I337MOYAFNC1_I337MVLUFNC1_HOME.tar didn't work, even though it was older and only a month apart from the FNE1....your phone likes what it likes I guess. The reason it took so long is it took between 6 to 36 hours to download from some of the 2012-2013 links given at 5-15kbps, I had to just wait and try other things while waiting for the 1.5GB Firmwares to download so I could try them.

Galaxy S4 (SGH-I337, AT&T) running Android 5.0.1 with baseband

Hello,
I have a Galaxy S4 (SGH-I337, AT&T) running Android 5.0.1 that I successfully rooted yesterday. I ran Root Checker to confirm. The phone worked fine. I then started deleting bloatware to free space. I rebooted 2-3 times during the day as I was deleting programs. Finally I deleting the wrong program/file.
Now the phone starts and goes to the page where I would normally need to enter my data encryption password, but, no keyboard exists. The phone seems fine, I could make an emergency phone call as it stands, but the lack of a keyboard to enter the password is a game stopper.
I am computer literate but not so on my phone. Am I stuck? Is there a solution?
Thank you in advance.
Mark
P.S. I have a backup using Titanium Backup. If I could get past the password screen, I could theoretically restore the deleted program/file.
