[Q] root for a day then gone? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

bought my new sprint galaxy s4 tuesday after having a rooted s2 for years. im pulling my hair out trying to root it. i used CF autoroot and had root access till my first reboot. then it and SU went away. been trying to re-root ever since. i manage to get CWM recovery to install but root will not re-install no matter what i try. im so frustrated!!!!! everything looks like it installs every way i try it but its not there no errors. im on stock MF9 sprint variant. i wish rwilco had that one on his site!!!! thats :crying:how i kept my S2 up to date

Try flashing agat's kernel. It has auto-root. Version 0.4.0 works very well.
It checks for root at start up. If its not there it will auto install.

Possible root option?

Is it possible to ODIN the phone back to the previous update so that you can root the device?
I just got my s4 less then a week ago and it was already at MF3

Unfortunately, you are stuck there until a fix is developed. There is no way back.
All the above are correct. Further: do not attempt to use Odin to return to MDB or MDL firmware. If it successfully flashes to the phone, it will cause a soft-brick (Emergency Mode) that's rather difficult to overcome right now.

how to unroot and go stock mf9

so cant really find anything that helps the answer I am looking for
Sprint updated my phone to mf9 than I rooted it
now I am thinking I want to go back to stock mf9 and clean the counter
I know I need to use triangle away and read that once you use it stop the reboot and load stock mf9 and it will make it look like everything is stock and wouldnt have tripped the counter
is this true?
I used odin to root it but other than the hotspot mod I dont really need it rooted
1) This goes in the Q&A forum.
2) There are tons of guides available on how to do this. Search is your friend.

i figure it was a developer issue since it was with a roted device, and it said to post in geneneral if it wasnt a specific rom issue

got it done 2 hours later and no brick

att s4 mf3 with safestrap/twrp running 4.2.2 but want to use CWM and run 4.4

So i rooted and used safestrap to install my 4.2.2 rom a little while back when that was all that was available. Now i cant find out how people are moving away from this old 4.2.2 junk and moving to 4.3 or 4.4
I know safestrap i have only works with certain TouchWiz roms (found that out when i triend to use CM a while back) and that is a headache only having really the plain google rom available to use.
any help would be appreciated, its been annoying
Read the "pinned" threads in General and Q&A and make sure to read the threads about 4.3 and 4.2 in the same places (General and Q&A sections). The questions you asked have been asked and answered several times already Good luck
Unfortunately on MF3 you only have safestrap and that's it. No CWM recovery exists.

THANKS!! wish that other person would of just said that! ive been looking and looking, and there is no possible way to get off MF3? odin and install a flash image from prior to MF3? anything? haha
i tried to install CWM like an idiot cause i couldnt find anything saying NO and it soft bricked my phone, got that all sorted out and now just back to the 4.2.2 google rom
just so plain and basic, its the same I had on my skyrocket for a year.. i bought the skyrocket the day it came out and got the s4 the day it came out too.... wanting 4.4 so bad lol
There is a q-fuse that is raised when updated to mf3 preventing a downgrade to happening.

Read the second post of this sticky thread, it states if you try to install a custom recovery on MF3 you will hose your device.
Lucky we have the MF3 odin files now so we can recover from soft bricks (that post was created before the MF3 files were leaked).
Glad to hear you got it sorted out though.

Does this mean we can now load an old version of the firmware from before mf3?

[Q] AT&T galaxy s4 mk2 recovery

I just rooted my AT&T galaxy S4 mk2 build and now i cant find a recovery for it anywhere. Do i just need to wait or is there something already out??Please help i haven't rooted a phone in 3 years and i'm just now getting back into it.
Go into the development section and get Safestrap. That's the only thing you can use, no true custom recovery. Make sure you read through the first pages of the thread and maybe some of the Q/A thread before doing anything.

[Q] Verizon galaxy note 3 roms!!!

Hi guys, I have a question regarding some roming stuff with the verizon version of the galaxy note 3. I am not new to roms by any means and I have been searching frantically to find one place with the complete answer im looking for. I made the early mistake of taking the OTA upgrade for KK, therefore I am currently running 4.4.2 with the NC4 build and NC4 baseband. Now while i have easily rooted my phone at this point with the towelroot. I also have had no problem getting the new 3.72 safestrap installed and running on my phone. My question now at this point is trying to figure out my next step with a new ROM I am trying install....I have been looking at all of my info to get the Hyperdrive ROM installed and I cant seem to find all the info I need in one location. Can I or can I not flash a new ROM to the NC4 baseband? I have seen some information where some people say I might be able to flash the NC2 kernal using ODIN and others say just trying to flash any ROM in general creates a black screen in which a battery pull needs to be done...yada yada.....? So in short, am I able to flash a ROM to the note 3 at this point or am I S.O.L? :crying:

Thanks...
Gee thanks?

I am in the same exact predicament. Every rom I install just gives me a black screen. I'd love a solution to this.

Check out the OP by hsbadr he has done some great work and he lists very specific instructions on how to complete the flash of firmware/modem and rom without any problems
flashing note 3 custom roms etc to avoid "mandatory updates.
I'm in the same boat. I read that there's a possibility I should flash NC2 but I can't find a write up or sticky that says how. However I just received a notice that pointed me to some threads and answered my questions on terminology. ThankYou DavidFlory!! I will formally thank you in the thread. Until I can clear up the NC4/NC2 question I plan on keeping the rooted KitKat I've got. I'm scared Verizon/Google will attack again with a mandatory "update." Who's phone is this? What if I firewalled Verizon updater? Or froze it? The other day I did something that had columns of 3 pt text cascading on my screens until I used Samsung Kies to back me up flash the stock rom again. Root was retained. This was a worthwhile exercise as I had gotten carried away downloading android utilities.

Do you have the link?
OK so I found the link, followed every step I could which took a couple hours of research to get everything together. ...I flashed the jasmine rom, everything seemed to work fine until the last file in which Odin was successful, then I get a black screen that doesn't go away with any other means than a battery pull. Luckily I used the new 3.75 so I was able to do my rom under a different slot than stock...but maybe that's also the problem? So I'm back with a wiped phone and no custom rom which is irritating

Do you know where I can get the link for the JasmineROM 1.7.2 because 8 flashed 2.0 and it is devouring my battery.
