[Root] Problem :\ - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hey this is my first thread here and I'm sorry I didn't make an introduction but, I just rooted my phone yesterday. It was successful and I made a backup using titanium but the thing is I started deleting apps and bloat ware from the uninstall in titanium and well I deleted this program called like touchwiz because it was installed with this software I downloaded from Google play called like Iphone 7 screen lock or something and anyways it came with it and changed some things in my settings and I agreed. Once I deleted that I couldn't press the home button since it was linked to the deleted touchwiz which apparently took control of the home button and well my home screen when completely black and so I restarted my phone. Next thing I know I can't get passed this loading screen. Please help :\ sorry for the bad light as my computers literally in my closet and the light bulb screw is too rusty to take out. Please help! h t t p: / / i . i m g u r . c o m / 8 M q C B n l . j p g / <- Remove the spaces it's been on like that for hours, I've even tried restarting it and it wouldn't change..

Well looks like you killed your launcher (and or part of the actual ROM). But...
What happens if you press menu? Do you have the option managing apps? If you do see if you can open Titanium and restore it. Or if you can open play store and search for a launcher - nova or something.
Have you tried to go into the stock recovery (assuming you haven't already added a custom one) and run factory reset?
Did you enable usb debug mode and unknow sources? If so you may be able to push over the needed apk (and .odex file if you are still on stock) via ADB.

Yes I'm still in stock I haven't installed anything custom, For factory reset isn't it like volume up, power, and home button?, umm so far when I press the menu nothing happens.. Do you think I can fix my phone over usb? to computer?

Well you could grab the stock MK2 Odex from here.
Then use ADB (via USB cable to you PC) to push the files over (if the phone shows up).
Problem is do you know the actual name of the file you deleted vs the 'displayed' name.
Or you could PC Odin a recovery (like Philz or TWRP) boot to that custom recovery and flash the above mentioned stock ROM (or actually any ROM in the dev section; so long as you follow the OP's flashing instructions)

If you install the odexed ROM then you shouldn't have to push anything. You should be good to go once installed. May have to do a battery pull to get first boot.
ADB = android debug bridge. It's a command line tool used to communicate with your device.

[Q] Please help, S4 Complete Backup (Nandroid) tool/ dicerctions needed

Hey everyone, I'm new to android game, I've been cracking iPhones since 1st gen, decided to challenge myself. I have an S4, rooted, but no CWM installed. I want to save the recovery so if any issues ever occur, I can just flash it and have it covered under warranty, and also to be ble to return to stock wen I sell the phone.
Is there a tool i can use to make a nandroid backup? On my Nexus 7, There is an all-in-one tool and I can make a nandroid straight from my PC. Is there anything similar for the s4? If not, how to I make a nandroid backup? thank you everyone for your help, I appreciate it
Odin back to stock if you ever need to.

I'm not entirely sure it's possible to do a nandroid backup without first having a custom recovery. However, it is "always" possible to use the Odin method to return to stock (including stock recovery). Personally, I installed TWRP and immediately did a full nandroid (including system, boot, cache, etc...) and I've frequently found myself restoring pieces of it as I manage to screw up different things. I did return my recovery back to stock once by using the "dd" method to flash the stock recovery.img onto the correct emmc block. There's instructions how to do this exactly on the TWRP homepage (make sure you get the correct phone - block numbers are different for different devices) - but instead of re-flashing TWRP, I pulled the recovery.img from the giant Odin image available here on XDA.
It may also be possible to use "dd" to pull a copy of your existing recovery image as well, but I've never tried it.

Thank you! I'll be installing TWRP today, what is Odin if I can ask? I've never heard of any of it from Nexus 7.
Also, If i do a titanium backup, can I easily restore apps with setting and save games while I'm running CM10.1?

You better find out what odin is because it's the only way you'll be installing twrp. And don't count on tibu restoring all your apps seamlessly. Never reinstall system apps.

I installed TWRP through GooManager. I looked up ODIN and got general info, hopefully I won't get stuck, but I'm sure I'll find my way around. Thank you so much for your help! I figured that sys apps will just be for stock, but i have a MC4 save that i don't want to lose ::cyclops: it looks like it's CM10.1 time for me!

Here's the thread that explains how to return to stock using Odin. Be prepared for a large download.
http://forum.xda-developers.com/showthread.php?t=2261573
In short, "Odin Mode" is the download mode that's built-in to just about every modern Samsung device, beginning as far back as the Captivate, afaik. Each device has a button combination to enter "download mode" or "odin mode". This special mode sometimes requires specific drivers to connect to your PC. Flashing stock firmware using this method is common, but with an unlocked bootloader, it could be used to flash about anything. It's like a secondary recovery in a sense. It's harder to destroy download mode, but still possible if you mess up the bootloader somehow.
For our device the easiest methods to get to download mode are:
- Hold down the power button until the device force-resets itself. The moment the device turns black, release the power button and begin holding down the Vol-Down button. The device with vibrate once as usual, but then you'll see a screen that you've never seen before (begins with "Warning!!").
- Using any shell, such as ADB Shell or a terminal emulator, give the command "reboot download". This may require root privileges, I'm not sure.
- There's apps for this - haven't tried them yet.
As for Titanium backup - I love this program and have purchased Pro (totally worth it). As others have said, it's a bad idea to backup/restore System apps. Only do so with extreme caution. It is possible to restore only the data from system apps, but again do so with caution.
While Google does its own job at re-installing apps after a factory reset (if you allow it to), it usually doesn't backup data for each app. I have a couple authenticator apps that I backup this way, and it works great for this. I've also managed to keep my copy of Angry Birds Samsung Edition from my Infuse. Other applications that have since disappeared from Google Play are still backed up and get migrated to each new device I purchase.
And for that matter, with almost every User application, you can easily back it up (with data) and restore it on a completely different ROM. When changing major android versions, you sometimes will find apps force-closing on you, requiring that you wipe their data... but I haven't had that problem in a long time.
You'll see some other things that you can backup, like SMS, Access Points, Bluetooth Pairings, etc. .... I recommend only restoring these with caution - especially cross-ROM or cross-device.
Okay, I'm done being long-winded. Good luck, have fun.
Good write up

Help Flashing Split View by Bigfau

I am wanting to install the LG G Flex Split View mod by Bigfau on my rooted LG G2 but I do not know how to "Flash in recovery and reboot."
Can anyone help me through this process? I was reading up on the flash guide here on the forum and saw that I needed a custom recovery installed before flashing. Is this really needed to just add the split view feature? If so, how can I go about doing this?
thx

yea, unfortunately, a custom recovery is needed to flash any mods or zips. It does not work with stock recovery. The only thing you can flash with stock recovery is a rom, but since you need gapps and so on for the rom to work properly, you need a custom recovery.
I find TWRP the easiest recovery to work with, here's the link: http://forum.xda-developers.com/showthread.php?t=2449679
There is no need for custom recovery... Use the Flash Gordon app from play store. All you need is root and busybox. You can flash zips but not ROMS..

Hmmm, two different answers. Thanks for the quick replies though.
I don't think I need any roms, I am just trying to take the zip file mod in the link and get it working on my stock LG G2. I know it will work on the stock Verizon phone, but I have no idea how to do the flashing.
If I use an app from the play store, I read that it may, "lack the ability to wipe the Dalvik cache (affecting the JIT compiler)." Will this be a problem for me?

I'll go ahead and try it out later today. I am not against installing a custom recovery if it is useful later. But I don't plan on installing any custom roms ever. Is there any use for a custom recovery outside of custom roms that cannot be accomplished by Flash Gordon App?

The ability to backup your device (make a NANDROID, as it is called). If you have a rooted device and intend to mess with it, I would say that a nandroid backup is a must . The good thing about a nandroid, something which Titanium Backup can't is to restore the whole system and boot. On the other hand, you might find some apps missing, so it's best to back up apps though Titanium Backup and your system/boot etc through Custom Recovery.
Oh and by the way, please tell me how the split-view thingy works once you have done it

To set split view whiich works wonders wen modding phones ? you have to set one of your nave bars to open it mine is set as the back button. Long press is why you just press the front nav bar in stead off tapping it. Correct me if im erong but i think you must also be running xposed installer with one of the g2 settings apps found in the playstore. I flashed split view using flashify and it works fine munis not being able to use the knock feature wen engaged.

I do not have xposed and holding down the back button launches the program for me.
The program works after installing it from recovery in TWRP, but after installation, I pressed wipe cache and it was in the process when my phone screen turned off. I couldn't get it to turn back on, and eventually just held down the power button for 10 seconds to get it to boot normally. It works now, but what can I do to avoid that happening again?
That im not too sure about wen i wipe my chace and dalvik it completes the action and just romdomly cuts the phone off. When ever your wiping i say the best thing to do is just too make sure you have a back in cases something goes wrong

[Q] [SOLVED] HELP / Device Stop Booting/Displaying

Hello All,
I'm on i9505 Stock Android L BTU with Stock Recovery and Rooted with CF Auto Root.
Today I installed Jrummy Toll Box in my device and acquired it Root Privileges but didnt made any changes thru it in system partition.
After that I rebooted my device in Recovery using Titanium Backup's Reboot option in settings.
It did rebooted to Samsung's Stock Recovery but after selecting Reboot Device screen remain Black only.
Samsung logo came up and after that all application force close errors comes up continuously only and nothing then after selecting OK for it.
Screen just remain BLACK only..
I also tried booting in safe mode in that also it remain Black and Force Close application errors only, Also SAFE MODE Logo Remain Active and light blinking there but I can not seen my device screen...
I actually need my device's data like Contacts, SMS and other Backups, that is the main concerned otherwise I can reflash flash and set it up back again like new..
Please Guide me what can be do in this situation...
Thanx in Advance...

Phone boots and screen remain Black and gives multiple force close errors for all applications.
only error messages are popping up not ROM Interface...
I can reboot device as well also select OK or Report Buttons for Errors...
It seems Device is unable to show ROM interface....
Did JRummy messed up Screen Density or anything else ?
You're confusing Samsung with another device. The stock recovery isn't replaced on boot or else our root guides would mention it.
It's safe to delete apps in this fashion as it's nearly identical to uninstalling the app.

Hello Strephon,
I didnt intended to confuse.
Was just being sure as I read the same here.
As well I also face it while flashing recovery in N7100...
but presently I have done all those steps but still issue is same,
Now I'm on TWRP and Removed that Folder as mentioned in earlier post but still device got stuck with Force Close Errors...
As I can access partition using TWRP File manger,
is it possible to read those Force Close errors, debug them and narrow down this issue ?
It seems Device is unable to show ROM interface....
Did JRummy messed up Screen Density or anything else ?
Please guide me further course of actions to resolve this ....
Thanx in advance ...
Hello Team,
I also tried TWRP /Advanced /Fix Permissions
As well moved data/app /com.kermadise.titanium.backup
But both failed to give solution...
I'm still facing same issue...
Kindly guide me further...
You tried reflashing the firmware you are on? That won't wipe anything.
No i didn't tried yet caused it will wipe recovery as well root privileges as well also give force close errors for GAPPS as it will be downgraded...
There is no way to recover device without flashing FW?

PLEASE HELP Fire Launcher Deleted Need Desperate Help

(Please note that my device is rooted using KingRoot)
So I was reorganising my Fire Launcher and I was deleting a few of the built in Kindle apps since I didnt use them, and without realising, Im pretty sure I deleted the Fire Launcher...
Now whenever I tap home I see my wallpaper for a second, then a black screen and then it takes me into my most recently used app. Is their any way to reinstall the launcher? And if not, can I recover my system from an earlier date / factory reset it? Im really worried ill have to factory reset it, but Im open to try anything.
Please help me, I really need this fixing.
UPDATE - Tried factory resetting and restoring from 7 days ago, and the backup file won't install. I'll try with a backup from 30/12/2015
Please, someone help. I desperately need this fixing.
PLEASE
IS ANYBODY GOING TO HELP?
I might seem impatient, but my parents check my device to see what i've been up to everyday, and if I can't get this fixed, then my parents will never forgive me.
SO CAN SOMEBODY PLEASE HELP ME?
Do you remember if you have adb on(usb debugging) if so push any random launcher apk to sd card and adb install it. If you dont then idk.

Installed nova using adb, worked perfectly. Thank you so so much.
the other thing you can do (i know this cause i borked apex while trying to move it to a system app the first time) is long press the home softkey. This "should" give you the option of opening a browser from which you can download a new launcher

SHEW!!! I used RootJunkySDL's supertool to downgrade the system (5.1.2), and got everything back to stock. ~sigh~ Also, happy to say, I re-used another RootJunkySDL Supertool to do everything proper! Root, OTA update blocked, lock screen ads removed, etc... ALL working like a proper Android now!! HOORAY!
HOW did you install using ADB?? I am having the same issue.... long story, but I factory reset tablet (wanted to start over)... I put the firelauncher back where it belongs (system, priv-apps), but apparently, not correctly, so I have blank screen, and no longer have root. Seriously want to shoot myself right now, along with the ad-bloated fire! ADB is on, and I can get to the screen by factory resetting, but how do I launch any app, or install anything???
OH please help... anyone.... please help.

Android is starting... Optimising app xx of xx on every boot

Hi all,
Have had my Nexus 10 with a few years now and rooted it not long after I got it, stuck with stock rom though.
All was fine until I updated to the latest LMY49H Build using NRT (Nexus Root Toolkit) which I always do and it has never let me down.
But with this update I get the swirling balls, Android boot screen then about 10 minutes of "Android is starting... Optimising app xx of xx". I have wiped via settings, via recovery (TWRP and stock), Flash Stock and Unroot (NRT), Root (NRT which wipes data), cleared cache, dalvik, data using TWRP but every time I end up with this optimising apps screen.
I have tried restoring previous versions at setup (apps, wallpapers etc.) and I have skipped all setup options for a clean fresh copy but always with the same result.
I have been looking around but didn't find someone running stock rom with the same problem, If I missed it then I'm sorry.
Please someone help me as I'm going on a trip soon and will need my tablet!
Could be your flash memory is wearing out. When you are using TWRP try copying a file then reboot into TWRP and see if the file is still there. If it is gone it is bad flash memory and you need a new motherboard...

Sorry I don't get what you mean. do you mean to flash a file? (or at least see if TWRP finds the file?)
e.g. copy a file, supersu.zip or something in downloads folder, then boot into TWRP to see if its in the folder ready to flash?
Oh I hope its not the motherboard, the tablet has hardly been used compared to others I know of.
Do you know if its safe to revert to a previous version of android using NRT? LMY49H or even G? I was happy enough with those versions and only updated thinking it would clear the security update (7.2mb) which I ended up doing manually anyway (Unroot & Update, install security update, Root).
I had a problem like this years ago when I flashed a ROM to my old Galaxy S4, flashing a different ROM fixed the problem then, I'm hoping it will now too!
Thanks for your help

Not flash your memory but check your: https://simple.wikipedia.org/wiki/Flash_memory
And yes it is safe to restock (another) ROM.

Right, I mean just copy a file to it that is not already there and rebooting it and seeing if the file is still there.
If it works then you probably don't have a hardware issue.
It is always worth trying to flash a known working rom, though you may need to hard reset to get it working.

Sorry, I know what flash memory is, I mean I didn't know what he meant by copy using TWRP.
I may try flash the previous LMY49H ROM then

OK cool, thanks for clearing that up..
This literally just started when I updated to the new ROM (LMY49J). I have done a full wipe already so hard reset shouldn't be a problem, nothing left on it now anyway. Think I may have done it already tho
Before the update I had a full TV series and a few movies saved into it and it had no problems playing/saving anything. Think I may try stock flash & unroot with LMY49H and see how that goes.. I'm away from it at the moment so hopefully will try tomorrow.
I have a feeling it is saving files though, displayed my old wallpaper when I restored from previous tablet option on setup. Must be saving this picture somewhere after initial download at setup. It is booting up eventually like, just after it optimizes the apps, maybe 5-10min.
What other issues could I be having?
You really have to create or copy something new and reboot the tablet to test. Files and setting will stay in the cache and so give the illusion working unless you reboot.
Also are you doing a clean shutdown via the menu after hitting the power button for no more than 2 seconds? Doing power off without going through menu can cause your behavior.

You have to copy something in recovery mode with twrp. From a different directory (or usb stick to your device) and then reboot to see if it is still there.
