Regain root from mobile - T-Mobile Samsung Galaxy S 4

In an attempt to unroot and return to stock for 4.4 OTA I flashed stock firmware and unrooted my device in the process, so far so good.
I reboot my phone after to initiate the OTA but of course I can't download the OTA because my device status is still custom and without root I can't triangle away or do anything.
I'm still trying to figure out how to get root back onto my phone from my phone since I don't have access to a computer where I'm at. I'm basically just screwed and also stuck on MDL baseband with a MK2 build running 4.3 stock so I'm getting no downloads at all. XDA the app itself too 10min to download
Any insight would be greatly appreciated...I knew I should have just waited until I I had access to a pc but I jumped the gun of course. I've been looking around a lot and the only methods of rooting I've found require or use a pc.

A stock firmware package makes the phone all stock. MDL baseband on an MK2 build means you didn't flash a stock firmware. Which 'stock' firmware did you flash?
As to root, did this 'stock' firmware also flash recovery? if it didn't you can download the recovery flashable supersu zip from chainfire's website into the phone and do it that way. Otherwise, I don't think there is a way to get root access from the OS itself, unless you find an exploit that grants su access so you can make system writable and push supersu.

I'm can't remember where I got this firmware from but, it was from a thread within the general section which stated it was stock so I'm just unsure on that part. I will try to root using your information given. This did return to stock recovery as well but when I try to flash anything through it I get a signature verification failure. I've never had this happen where baseband and build didn't match after returning to a stock firmware. My guess is that I just used something I shouldn't have. Thanks for the help.

After downloading the supersu and attempting to flash it through stock recovery, I'm still getting signature verification failure then the device reboots.

Unfortunately, rooting or installing custom recovery needs to be done through a computer. As of this moment, there are no root exploits that can be done via the phone itself. I'm sorry.

That's because you need a custom recovery, it's why I asked whether the firmware you flashed replaced recovery or not.
As vigz said, you need a computer to at least flash cf root with odin.

Okay I've pretty much come to that conclusion after continuously searching with no solid method. I'll just have to deal with the baseband problem for now until I get back home. Wifi toggle doesn't work at all either. Is that a baseband problem, correct?

[Q] SPH-L900 update, already rooted?

Hi, So about 5 days ago I rooted my Sprint Samsung Galaxy Note II using the video Max Lee made from galaxynote2root(dot)com, and about 36 hours later I get a notification for an OTA update. I kept off updating because I didn't really know what to do. I'm really new to this and there's still a lot I have to learn. Anyway, I ran the update and it restarted my phone and went to the TWRP screen. I restarted the system and it stopped notifying me about the update. And I checked and it says that my system is up to date. And I also checked to see if I still have root with a root checker app I downloaded, and it said I still had root also. So, was the app wrong and I don't have root anymore? And after I updated should I have restored the backup I made when I originally rooted? Also, thanks for any help, I've looked around and couldn't find anyone else with this question.
Your phone automatically downloaded the update and was waiting to be powercycled to install. However it failed to install because it requires stock recovery to install and you dont have it. So your phone boots back up and all is good with no changess.

I also have the same issues. I did a back up of my original roms and re installed using twrp . I down load the new update and when its going to restart it goes into to twrp menu. From there i am stuck on what to do.
It failed because you're not on stock recovery. If flashing the stock ota, you need stock recovery.
If you have twrp recovery, read and review this thread:

Before I rooted my note I made a back up using twrp. Is that not a stock recovery file ?.
Yes and no. That's basically just a backup of the stock rom that's only flashable via twrp since that is the recovery used to create the nand. So yes it is a recovery but only flashable thru twrp.

Ok well I did recovered using twrp and it installed and took me back that state before the root. I was thinking that took me back to original state and then update . I did download the update but as it was restarting the twrp home sceen would pop up and not update. So now I have no root or new update. Its funny it was easier to root then to unroot.
The link I posted above would have allowed you to flash new firmware and ma7 through twrp. No unroot reroot required. ..
And like stated, you can't update the stock ota update without stock recovery.

There are 6 links on that thread, one for odex and deodex (which I have no idea what it does), and then the 2 links for ma7 one all in one, and one just regular. And then there are another set of 2 links for the kernals, one regular and one modified. I guess what I'm asking is, how do I install these and which ones should I install? I have no idea what any of them do anyway.
How
how do we go about it and what files exactly do we need? why is everyone so vague?

I have flashed over 30 SPH-L900 (Note 2) fron Sprint to Boost.
I do everything on CDMA (paid version) 3.9.
Since the L.900VPAMAZ update I can no longer change the esn to Boost because the 16 digit CDMA passcode is no longer the default passcode for the Note 2. The old pascode: 01F2030F5F678FF9 still works for the Galaxy S2 and S3 but is no longer recognized on CDMA Workshop or QXDM.
If anyone knows the new passcode please let me know.
If I find it I will post it so that noone else has this problem.
Thanks!

Update without OTA and Kies

Been searching and I can't figure this out.
I have a rooted S3 and I can't get 4.1.2 OTA.
I also have no access to a PC I can install Kies on.
What is another solution to getting the update on a rooted S3?
Do you have a custom recovery installed? If so, you can just flash a debloated stock 4.1.2 ROM from the development section.

Yeah I have CWM recovery.
This shouldn't mess with settings right? the reason I haven't messed with ROMs on this one is because it's all set up like I like it.
EDIT: NV can't flash with Odin. I have a Chromebook. I need a zip to send over Kies air and flash through CWM

I never recommend dirty flashing (flashing one ROM over another, especially when updating to a newer version of android) it eventually just leads to problems and you'll have to start over again sooner or later.
If you do it the right way, you will have to re-setup the ROM again, pictures, music and files like that will be fine but you'll lose all of your settings.
If you do decide to flash ROMs, before you do, search how to backup your imei, you'll be glad you did if you ever lose it.

It's stock rooted is all, don't want to delete everything just for 4.1.2.
I'll keep searching but it would be easiest to find the update zip file, especially since I won't have access to Odin or anything else to back stuff up and flash in an efficient way
EDIT:
Would sending this zip to the sdcard and apply update through CWM work?

That's the firmware for Odin it looks like. If you want you can just download the OTA from my firmware thread. Flash in CWM and it should work and allow you to preserve root. Probably the easiest way to get what you want. If you can use Odin from another computer, root66 is definitely preferred, but there's more than one way to do it.
I agree about the dirty flashing, for the most part. Since you are simply updating the stock firmware, you should be fine. Clean is better of course, but it's up to you. Without starting clean.you do run the risk of having issues down the road, and then you wouldn't even know why.
If you decide to try the OTA, please take a few min to read what I've got there.

[Q] Help switching from SuperSU to Superuser, please!!!

Hello,
So, I have the T-Mobile S4, obviously, and I updated to 4.3 using Kies. Well, long story short, after the updated I couldn't use WiFi at all. I ended up using Odin and putting the stock firmware back on, and that fixed everything.
Now, I rooted it using this thread http://forum.xda-developers.com/showthread.php?t=1980683 but, the SuperSU root isn't letting me use OBackup, now. Before, when I had Superuser, it let me use it just fine.
Is there any way to switch from SuperSU to Superuser? I've been reading a few threads but they are all for 4.2.2 and I'm not sure if it'll work on 4.3. I read on one of the threads to use "CWM recovery" and use Odin and that would work, but again, that's 4.2.2.
Any ideas would be great.
Have you tried downloading it from the playstore?

The easiest way to solve the problem is to re-odin flash stock 4.2.2 firmware.
After that download CF-AUTOROOT and odin flash it.
After that you will be fully rooted and all apps which require root will work again.
Here is the direct download link for cf-autoroot: http://download.chainfire.eu/328/CF...jfltetmo-jfltetmo-sghm919.zip?retrieve_file=1
p.s. you might need to re-flash cwm or twrp custom recovery.
Good luck!

Yeah; I tried downloading it from the playstore, but all it tells me once I open it is that the it is oudated and needs to update. I hit "Update" and then it crashes the app, and restarts the phone into recovery mode with no prompts except "reboot phone".
And the thing is I do NOT want to go back to 4.2.2. I want to find a way back to Superuser instead of SuperSU.

when booting i received a message at the upper left of the screen: SEANDROID not enforcing( or something like it)
fortunately, i was able to restore my phone to M919UVUEMK2 via samsung kies. so, my device is working again. Albeit, with a voided warranty, but i still want to root it and install cyanogenmod.
is this still possible? any help would be greatly appreciated.:fingers-crossed: i'm sure there are others thinking the same thing.

Would this trigger Knox? cause i did the OTA Update without reading about it first which i should of done -__- i want to re-root my phone
To be honest I didn't check I assume so as in boot it says se not enforcing but I didn't check download mode. Using the CyanogenMod install is easy an install root an custom recovery for you. If you are worried about Knox just wait or search for the method to root without tripping Knox.

Tried update, now says software is up to date

Hello,
I have always thought that OTA update would fail with a custom recovery. However after reading about another user's experience I decided to try it. This person stated that when they did the update CWM warned them that it would be replaced and asked if they wanted to fix it. It also warned that they would lose root and asked if they wanted to fix it. Sound familiar to anyone?
I did download the update but when I tried to install it failed. Now AT&T says my software is up to date, which is not true.
I am still on 4.1.2, rooted, CWM installed. Best way to upgrade now? I can't even find the OTA upgrade file that I downloaded.

From my experience with 3 i747m phones, rooted systems well not take an ota update.
Yup, you cannot get the ota if rooted, or with a custom recovery. You need to be full stock. Best way is a fresh firmware flash and factory reset.
I don't have to install OTA, I just wanted to update to the latest official AT&T version. Is there a flashable available that will work coming from 4.1.2?
By the way I used triangle away, downloaded update again, thought it was going to work but the update crashed

The latest firmware that's available is the 4.3 build. Havent been able to make a working one for 4.4.2 yet. But you can update using that firmware then use one of the threads in this section to update to kk.
Ok confused. Not sure how to install 4.3. Have read about bootloaders and modems needed before flashing. Guess I will have to keep reading. How to gy from 4.1.2 rooted, CWM, to the latest official which now I think is 4.3?

You can either follow the OP through step 4, or flash the firmware from this thread using Odin. http://forum.xda-developers.com/showthread.php?t=2722660
After that you can follow the remaining steps in this OP, or try to get the official ota to update to 4.4.2.
Since you do not have the 4.3 bootloader, you could start fresh by installing stock 4.1.1 from sammobile.com using Odin and then just keep running OTA until you get to 4.4.2. Remember, using Odin will wipe everything on the phone so make sure you backup your important data.

Everytime I try to download something from Sammobile.com my AVG pops up a warning. Is this normal? I haven't yet made it through all of their stalls, installs, etc. to get to downloading the actually firmware.
Used to love AVG. But I think theyve gone downhill and this is a perfect example. Its a false positive. (Unless your browsers been hijacked or youre clicking on a bad/fake link).
Ive been using sammobile for years and never had a single problem.
I have been using sammobile for quite some time.
The site is legit. Maybe avg is causing the problem. I can download with no problem.
Not trying to be annoying, as I said haven't done any of this for a while but.....could I not flash a stock recovery, use triangle away, unroot, and then get the ota to work?

You could try that but there is no guarantee that it'll take the OTA update after going through the procedure you described.
If you removed too many Samsung Apps, that may cause the OTA update to fail as well.
Don't think I removed any Samsung or ATT apps I just had them disabled. Since I tried to run the update though they have all resurrected themselves. I have never flashed a stock recovery or unrooted before though

All I can say is try it and see what happens. If it doesn't work, the simplest would be to restore to completely stock and start the OTA update process.

I guess I can't read, but so far I have been unable to download the 4.1.1 from sammobile. I have gotten some media player, etc. which I don't know whether is still on my computer or not, but have not gotten to the download of the actual software.
Do I have to agree to everything that they try to get me to install?
You are probably hitting one of the ads that put up fake download buttons. Just a guess though.
It seems that registering helps
