Just in case... - Sprint Galaxy S 5 Q&A, Help & Troubleshooting

I have the GS5 with nd2, rooted (towel root) and 0x0 KNOXX. I am trying to keep the KNOXX virgin for now. I have dabbled enough and am learning more and more and have been able to make a lot of the mods to my GS5 manually. There are a few more that if I can get them to work, I won't need a custom ROM or flashable zips (my hope). My concern is that some of the ones I have not done yet are getting into code. I am fairly comfortable working on code and have done a little programing here and there. The worry is that I might mess up something and be stuck with a bricked phone.
The question has to do with odin, custom recoveries and stock OS .tar files. Assuming I mess something up to the point where I cannot load the OS to replace the changed file with my original (I am smart enough to save any originals before I start modding them), can I use odin, ADB or such to push the original back? Or worst case use odin to push a stock .tar and start over?
I am pretty sure that with a custom recovery and or nandroid backup, I can fix most problems, but trying to avoid custom recovery if possible.

Between the Xposed Installer and TDunham's "smali" works found at http://forum.xda-developers.com/showthread.php?t=2799050 , you should be able to mod a whole lot without a custom recovery. At least having TiBu for backing apps is good. You will just have to factory reset if you mess up.
My opinion? Take the leap, bro.

Rooting, Flashing, Backing up And Installing New Boot Loader

Hi guys,
I just got a SGS4G about a week ago and I would like to tweak it a little bit but I do have some concerns. This is my first android smartphone
Here are my concerns:
I would like to do a Backup of my ROM in case I ever want to go back to it. How could I do that? Do I need to install a bootloader other than the one that comes with the phone? if yes which one should I install?
I have rooted my phone and would like to get rid of a bunch of apps but was reading that if you remove some of the apps it could cause the phone to malfuncion. Is there a compiled a list of apps that should not be removed? or this is just not true?
When I'm ready to install a Stock ROM how do I do that? Via Odin? (I can look for some guide if it's via Odin)
Can anyone tell me what would be the benefit of installing Deodexed instead of using the Stock ROM?
Will i always me able to come back to my Stock ROM once i figure how to create a backup ROM?
Am I missing any important point that I should know about?
I would really appreciate if you can help clarify this doubts that I got before i try to do anything.
Thanks
i'm new to all of this too but ill try to answer some questions. Although, I think this thread should NOT be in development and should be in general. I personally have read through a lot of threads to get the answers that I was seeking for.
As far as backup goes, I think its possible through Odin via dump option? don't quote me on that, I have not had to do that before, nor have I read up on it. bootloader as far as i see, i did not need it.
there is a thread in here with virgin rom request, LOOK for it.
There is NO compiled list of apps that you can or cannot delete, but if you read, there is a dl for BLOATWARE, use that as a template to what you want deleted.
Right now, ODIN is the only way that you can flash your phone, and use the two roms listed in this development thread.
From what i read a deodexed rom just helps with file system and structure. I think?
you will always be able to go back to stock, if you have the virgin rom.
Imo, you should read up/skim through every thread in here to see what is available, problems people are having and the fixes for them. I know there is alot of information in here and it maybe overwhelming, but there were 172 views of this thread without any replies because us noobs need to READ/SEARCH. Thats the answers we'll get if we continue to make new threads. Just fyi if your new to forums.
Moved as not android development.
As newbie you should first read and use search
then if you dont see question you want, you just ask it
And about Roms , well i tried that deox v2.2 and didnt like it , switched to stock with removed bloat and love it more but thats for different thread
Well thanks for you answers and I do apologize for posting this here. I didn't know. I think i will go with what you have done. Stock ROM without bloatware. Did you flash the Stock ROM from this forum? or did you just deleted the apps one by one?
I will do the fota fix as well.

ClockWorkMod is the preferred way to backup your ROM, but it does not seem to be working on the SGS4G currently. I was messing with it one night and actually think I got it to backup the Rom one time but I cannot guarantee that I did because I was working on a supposed fix and did not get a chance to copy the backup file to my computer before it got wiped off my SD card. The process is called nandroid backup. If you have a virgin phone and want a clean backup of your ROM you might want to wait until the fix comes out for CWM.
Once you root your phone you can install Titainum backup. That allows you to backup your apps/Data/System settings. At least that’s what it says it does. From what I’ve read, the best way to backup your apps is with ADB which is part of the Software Development Kit. You can also use Android Commander which uses ADB to Pull your apps to your computer and make a backup there. Check http://forum.xda-developers.com/showthread.php?t=1010006 for info on SDK and ADB commands. There is also a direction to making new apps install to your SD card natively. This link http://forum.xda-developers.com/showthread.php?t=1001202 also shows that command and how to Reverse/Check status of settings.
The Noobs guide to Oden covers the basics to flashing your ROM fairly well: http://forum.xda-developers.com/showthread.php?t=1001759
The [ROM-ODIN]T959VUVKB5 Stock + Root and [ROM-ODIN] Deodexed KB5 Enhanced v2.2 are the two ROMs that are working now for most people. The first is Odexed the second is Deodexed. Odexed is how it comes stock and takes up less room but making modifications or taking apks from other roms is hard, While Deodexed allows modders to work on the apks & easily change stuff like themes. (Description Taken from Damage's DamageControl Thread) My suggestion is to have some patience and wait for ClockWorkMod to be updated and working for the SGS4G before you dive in too deep. Take some time to look around the 4g posts and read as much as you can to get familiar with what is working and what is not. Check some of the threads with locks on them to see what not to do. There is a wealth of information in these pages.

Thanks man! Really helpful. I will read into these threads and probably will wait for the clockwork to work for SGS4G.
I really don't see the advantage of flashing to Deodexed. Maybe i'm missing something?

Development Help

Hey guys I have been working on building a ROM based on the current OTA, pre-rooted and deodexed and a few other perks thrown in. At any rate, this is my first ROM and while I would be comfortable flashing a ROM for experimenting with to my Kindle or my Dinc because they have bootloaders that are worth something, the problem with the D2G is that if I get caught in a bootloop I don't know what to do because as far as I know there is no way to access CWM from outside of rebooting to it from a rooted ROM. Does anyone know what to do because I would like to get this development rolling but I would rather not run the risk of bricking my phone if I can help it. Thanks!
In other words, in the case that i get a bootloop how would I go about recovering my device? flash a stock update.zip through stock recovery?
OTA updates can only be installed on top of stock firmware they are made for. If there are altered files in /system that are on the check list, it won't work.

Stock GB Rogers to JB questions

I've been sitting on my stock Rogers Infuse 4G since I got it, hoping that they would at the very least release an update to ICS. I've pretty much given up all hope, especially now since the Infuse was listed as one of the "violators" in the recent lawsuit. So, in giving up there, I've started to try and get up to speed with what's available in terms of custom ROMs for the Infuse, etc...
I previously had a Captivate (seems like I pick the wrong phones) and have kept that one stock as well (now my wife's phone) aside from the official 2.3.3 update Samsung came out with for it. I checked in here once in a while to try and keep track of some of the updates as I thought about going for a custom rom, but I never had the balls to try anything (I've only ever flashed one phone in my life, and it was bought 2nd hand for $20 ) since I actually *must have* a working phone due to having a kid (daycare calls are kind of important!). However checking today, it seems like I am totally out of the loop and I just don't have the time to try and wade through thousands of pages on various threads to find out what the current "ways" are and such... but I know what I want to achieve so I'm hoping you folks are nice enough to at the very least give me a "search you noob" and point me to some threads :silly:
Since I'm totally stock, from what I'm gathering I think I need (and really I more of need a complete checklist of things to do rather than a "do it for me" kind of thing) to do is:
1) jot down my modem and apn settings and such (already done)
2) back up everything i need, pop out sd card (know how to do this)
3) wipe/clear to factory default (... and this)
4) back up the current rom - everything in case I want to return back to exactly the way the phone is stock
5) figure out what i need to do to flash CWM or something so I have the necessary recovery mode options?
6) flash to ICS (since from what I gather, I need to do that if I want to go to JB)?
7) follow instructions I found on the unnoficial CM10 JB thread to flash to JB
?) flash a new kernel? (is this done already during a rom flash; are there any new kernels?)
As commented, I can figure out 1-3 since I'm not stupid, but I have no idea what is even needed to do 4, nor do I know exactly all the tiny, necessary, steps to do the rest after that... especially since reading some things it seems like most of this is for AT&T users and since I'm on Rogers with a I997R (I assume the R means Rogers), I don't want to mess up my modem or other things to prevent the phone working for me... and these are the steps I'm hoping people can help me with.
So far, in prep, I've noted my phone info (basically everything in Phone settings) and I can back up all my apps and such that I care about, and I've downloaded the unofficial CM10 JB download and the Google apps apk as well, and on the same thread was a link to a 1-click ICS flash or something... so I got that too. Since I want to end up with JB, I'm not too concerned (or should I be?) with it being AT&T stuff to get to ICS, since it's the JB flash that I'd really want to ensure works for me.
Is anyone willing to help me out? I really wish I didn't have to be the "next loser" to make a thread like this but I just haven't had the time to be able to keep up with all the info going around (voodoo mods and whatever else?!) to be able to make sense of all this myself!
Thank you!
This looks like a good place for you to start
http://forum.xda-developers.com/showthread.php?t=1197248&highlight=how+to+root+rogers
First thing to do of course is read, read, read. Understanding what you are doing and why you are doing it is the most valuable resource you can have.
The gist of it is though: to install the custom updated roms, you need root. For Rogers infuse users that is very easy to do; all you have to do is install a rooted kernel in odin. After you do that you make a nandroid (and/or EFS) backup, and install whatever rom you want. CM9 and CM10 have their own kernel, so don't worry about that.
adfurgerson posted the step-by-step guide above me, although the links in the OP may be down. I have the mirrors here: http://minus.com/moAvVibed/
the 3 files in there are:
Odin_Infused_Gingerbread_Kernel_v1.zip - This is the rooted kernel you are flashing
Odin_Stock_Rogers_UXKG3_Kernel.zip - This is the stock rogers unrooted kernel if you want to unroot and go COMPLETELY stock for whatever reason (I doubt you will ever need to use this tbh)
Odin_UXKG3_rooted_no_bootloaders_v2.zip - The stock Rogers FIRMWARE. If you ever mess up you use this to "start from scratch". You will still be rooted though if you don't use the stock kernel above.
So yeah, just flash the kernel in odin as described in the above thread and you will have root + cwm.
From there you reboot into cwm (turn off, turn on holding vol+ and vol- buttons) and make a nandroid backup of your stock rogers rom (or an EFS backup with the infuse toolkit: click here), flash CM9 as per the instructions in the OP, and finally CM10 as per the instructions in the OP.
Also remember:
1. The infuse is almost impossible to hard brick. The only real way to do so is to improperly flash bootloaders, which a rogers infuse user will never have to do. Only AT&T users coming from Froyo have to do it. So keep that in mind.
2. On the chance that you get soft-bricked (screen won't go past samsung logo for example) you can always go back to flashing the stock rom/rooted kernel again in odin and start all over again.
The only thing that I can add to Threi's excellent reply is to mention the one click to ICS. It is in the first post of Scott's CM10 thread,it should give you the ICS recovery that is needed to flash JB without flashing a full ICS ROM.
I suppose I should have mentioned that I also have rooted my phone already (used SuperOneClick, worked fine). Is there any reason why I would use that "rooted kernel" versus just having root on my phone (ie, having su installed... dunno what else it did, I don't think it did anything to my kernel)?
I guess my biggest unknown is all the backup processes that can be done and how to do them? Is "nandroid" a one stop shop for doing backups of everything? Although there's the complete stock Rogers rom linked above (which I'll nab anyways!), I was thinking I would try to make a complete copy of my own phone (just in case)... I guess next step is to search for "nanroid"
Are there any other backup tools I could use/check out (not apk backup tools... those are easily located in the app store, or performed with adb myself).

Flashing a kernel is how you obtain cwm which allows you to flash custom ROMs(cwm is clockwork mod recovery). A nandroid is a backup you create in cwm that is copy of your phone that will return your phone to the exact state it was at the time backup was made.

Aha, perfect description. I didn't realize I had to get a new kernel to have CWM... and I'm guessing because of signing and such, that a custom kernel (with CWM) is required in order to flash a non-signed rom, which is why you couldn't just do it on stock, right?
Ok, so now armed with that info that clears up a lot, I guess I have just one question left (which I can probably find the answer to with some searching). I have read what that voodoo lagfix is and is this something that is standard now on all kernels (because if it can cause issues, I'd rather just have a kernel without it)? Are there any "rooted" kernels without the lagfix built in so I don't have to remember about disabling the lagfix? ...or is there a way to install CWM on to my current kernel?
*edit* Ok, I realize I might be a bit too picky about the voodoo lagfix thing. I found two good threads on dealing with Rogers specifically, so I'll read over those (and suck it up about voodoo) and see how it goes. Since my vacation got unfortunately cancelled due to a sick kid, I have some time to experiment this weekend... hopefully ending up with JB on my phone!
Glad to see your on you're on the way to JB. After you install a custom kernel be sure to make a nandroid in the backup and restore option of CWM before you flash a ROM. That is like your safety net, if you wiped everything and had a bad download that wouldn't install, you will have a nandroid to restore.

Yep, just flashed the rooted cwm kernel and performed a backup. I read somewhere that you can/should back up your efs in case you lose your imei... so I'm just going to quickly look in to that, then i wipe and do some flashes to jb... shouldn't take long hopefully!
Ok, I seem to be stuck at trying to get the one-click ICS install to work. I've got the EZUpdater package to ensure I have the right drivers, yet everything I try with the one-click seems to tell me that the drivers aren't installed and then launches an installer which also doesn't seem to detect the phone... yet EZUpdater will run fine, etc...
I'm just about to reboot and launch device driver in a mode to list all hidden/previously installed devices and nuke them from history to hopefully purge my system of all traces of any drivers and install EZUpdater one more time to get the drivers installed.
Any reason why my phone wouldn't show up in this one-click (it uses heimdall or whatever) program, but seems to work in most everything else (adb even runs fine)?
*edit*
Got it all working! I couldn't get the one-click ICS to work for the life of me... it just didn't see the drivers even though they were there and working. I guessed maybe it had to do with me running Windows 7 x64 and having x64 drivers, but the one-click maybe being 32bit. I even tried installing the x64 Java JRE but didn't seem to make any difference.
I ended up having to flash CM9 which worked fine, then going to CM10. Had no issues doing that... wish I had just tried that before since that one-click wasted hours of my day and got me somewhat frustrated!

[Q] Titanium BU WITHOUT root?

I have a Samsung gs3 that bricked on me last week while trying to do some updates. It was rooted and running automated backups twice a week. I've now got a GS5 running 5.0, and I'm leery of rooting just yet. Is there any hope of recovering any portion of my missing app data without rooting?
Thanks!
Rooting on gs5 is safe. I rooted the day after I bought it.
Rooting is the best way to get app data and honestly it's safe.
Just follow instructions on the forum and you should be good to go.
Which procedure did you use? It sounds like there could be issued coming from 5.0, as opposed to starting at 4.4.4 and flashing forward...

look in the forums. I used CF Auto Root through ODIN.
I started with OA6 (full tar) and did it from there.
OA6 tar.
CF Auto Root
KTOONSEZ TWRP Recovery
and then MOAR 6.1 (with extra stuff)
then KTOONSEZ kernal (some folks stick with stock, FYI)
Ok, I feel like I should understand what you wrote, but I can't quite sort out how to get there... Given how I screwed up last week and bricked my s3, I'm a little gun shy.
I just want to get to rooted stock, but it appears I need to go back to 4.4.x/NE5 to root to start with, right? Then flash a custom recovery, (trip Knox, which is fine).
From there, how do I get back to 5.0/OA6 ?
I know enough to be dangerous (as evidenced by the brick on my desk)...

Let me see if I can help
You can root the S5 from Android 5.0 (Lollipop), you don't have to downgrade.
Download this file to your PC: http://download.chainfire.eu/408/CF-Root/CF-Auto-Root/CF-Auto-Root-kltespr-kltespr-smg900p.zip
It's CF-Auto Root for the Sprint S5 on Lollipop. Unzip it on your PC using something like 7-Zip.
After you unzip it, use Odin to root your S5. Put your phone in download mode by shutting it down (pull the battery, don't use any kind of menu to boot into download mode. Put battery back in and go into download mode by holding Volume DOWN, Home button and Power button. You'll see a screen to press Volume UP to continue. Hook up your phone via USB.
Start Odin. You should see a blue COM setting in the upper left side of Odin. If you don't, then you need to install the USB drivers on your PC. (If that's the case, stop there as you'll need to find and install them.
If everything is ok, then click the PDA or AP button (depends on which version of Odin you have) and browse to the file you un-zipped and select the .tar.md5 file and click Start. When it finishes, it will reboot your phone. At this point I don't remember if CF-Autoroot includes SuperSU, but if not, download from the Playstore and you're rooted.
As far as your original issue of wanting to restore app data, it isn't advisable as your wanting to restore from the S3 on Kitkat to the S5 on Lollipop. You're just asking for headaches if you do it. But if you're going to try, install a custom recovery and do a nanoid backup first.
Hope this helps
Thanks for that! That does help.
I almost think I need to just buy a replacement s3, root it, pull all the backup data back down, transfer it to the new phone, then turn back around and sell it...? I thought I had most of the data I needed died on the SD card, but there were apparently a couple apps I never set up properly to do so, and those are the ones I'm trying to get back.

How to dump/backup my own stock firmware without root (nandroid like?)

Hi Team,
Prior any play with my new G930FD I want to fully backup all firmware elements like radio, EFS, etc. to bring it back to state as it is now.
Once this is done I can play with adding root, etc.
Thought process was that it should be possible with ODIN, but I can't find a guide treating this subject.
In the past I've used to use Philz Touch on S4 LTE and all worked fine besides I've had troubles to restore NAND backups. Needed to move back from LineageOS to older CyanogenMOD (due to some issues) only to find out that old backup was not working anymore. I've tested backup earlier but it was years ago and didn't re-test procedure anymore.
Since don't want to run into any similar situation that can't revert to state as I'm in now, thought will asks you experts here.
In the past I'd think about process of booting recovery from computer via fastboot, performing required backup to SD card and them doing whatever I'd need to do.
Checking all guides (and believe me I've spent plenty of time trying to find it) all I was finding was that it required root to perform dump, i.e. using su with dd.
I've no issue to type in terminal as used to patch kernel back in times of kernel v2.4.
I just want to make sure that throughout the process of getting root, I'll have always a roll-back procedure and don't want to trip Knox and other flags, whilst if possible keeping OTA access (based on guides here, this should be possible).
Please advise on steps I should take to backup all current data with any tool or point me to place I've missed as I'm sure someone has described it already and I'm just being blind.
Thanks in advance!

Please advise on steps I should take to backup all current data with any tool or point me to place I've missed as I'm sure someone has described it already and I'm just being blind.
Thanks in advance!

There's a method to do that but I'm afraid it's not for our phone, because you see for the devices that can install twrp with fastboot command you can make a command that only boots twrp "fastboot boot recovery" or something like that, I don't remember clearly,instead of "fastboot flash xxxx" but we can't flash twrp with fastboot so that's impossible for us I think, I strongly advise you not to try these methods because you might end up bricking your device, if you are afraid you might mess up your phone stay away from the root and flashing, AFAIK there's no other method than the one with Odin and formatting data.
Thanks for answer, hoped I was just missing something.
Might be interesting for some people, and in fact for myself too.
I've found out that baseband version I've is not listed at Sammobile:
https://www.sammobile.com/firmwares/galaxy-s7/SM-G930FD/
It is:
G930FXXU1DQEJ
Not sure how to proceed should I run into issues?
I do also consider downgrading back to Marshmallow to take advantage of Xposed.
btw. it was all so easy, nice and sweet back in times of my S4 LTE play and now it is all so complicated, that even encryption with root seems to be so, so dangerous. :-S

Long time ago... though forgot to make sure I say thank you! I've had laptop OS level issues and missed to say that. Sorry.
