[Q] Galaxy S4 Root

I rooted my AT&T Galaxy S4 i337 a while back using Motochopper and it worked absolutely fine. After installing Cyanogenmod, I decided to go back to stock. I used triangle away and Odin to return myself back to stock, however, I always had issues. When I would recovery boot, I got an error and I couldn't wipe my cache partition. I tried to re-root my phone today using Motochopper and then Odin, but neither of them worked. I got a fail on both of them. Motochopper installed Supersu on my device, but didn't actually give me root access, and Odin just gave me a fail. Now, my phone is working with stock, but I still get errors in recovery mode and I can't root. Can someone please help!?

That's what i was afraid of. With mf3 you can't root with motorchopper or flash roms like you could on mdl. You also can't put on a custom recovery. Give me a second and I'll give you some links.

MF3 has a completely different root and recovery method now. Search the threads and you'll find them. Unfortunately it's pretty risky as you won't be able to flash back to stock using ODIN on MF3.

Because you were on mdl firmware. After you Odin'd it had to have taken the ota update to mf3.

Ok, so I read the links. Now, I'm not so much interested in rooting as I am getting my phone straight. Is there any way to get back to mdl? Will the rumored 4.3 update this month fix that? When I tried to update or recover with Samsung Kies, it said my phone wasn't compatible to recover. Does that mean I won't be able to get the update?

First, there is no way to go back to mdl. Idk if you'll be able to get the 4.3 update but I would assume so since you are on the stick firmware now. But, each new update is going to make it harder to root your phone or run custom roms. So you probably need to choose whether you want to keep your phone stock and take updates if and when they come out. Or have some snooty to run custom roms and root your device and put safestrap on.

[Q] How to get back to complete stock? Wifi Won't Enable

Received an ota update on 11/30/13. Installed and can no longer enable wifi. There are a few threads with similar problems but, the fixes in them don't seem to be working for me. I tried to Odin back to a pre update version. Unfortunately Odin wouldn't work. However, was able to use Odin to install TWRP. I've been reading on xda for the past 4 days. I've tried several methods mentioned in some of the posts to revert. None seem to work. Would someone please help with some step by step instructions on how to get my phone back to stock. I want to remove TWRP and re-install the stock recovery and have the latest sprint s4 stock rom.

How did you take the OTA. It looks like you flashed the MK2 ROM that's is in Dev section. Of you had taken the real OTA it would have updated your baseband (modem) as well.
I've heard you can use MJA tar while on MK2.

Not sure about the original poster but I updated from the Sprint notification I got. Maybe I should have flashed the update from the dev section. Should I try flashing the MJA firmware again?

I was able to fix mine by downloading the stock MJA rom and flashing it through Odin. Then take the OTA update and re-root (if you want root again).

I did the same. I initially installed the update manually via stock recovery and lost wifi. ODIN back to stock MJA fixed wifi, and then repeated the manual update. Wifi works fine now. I did not do any data wipes going back and forth, and have no adverse effects so far.

[Q] New User. I Need Help.

I need help. I got a Samsung Galaxy S4 (SGH - I337) Rooted from AT&T. I got two problems.
First I cannot update my version from JellyBean 4.2 to 4.3. Every time I had downloaded the update when the device restarts and it reaches 21% on the update it said's "Update Fail". What can I do?!
NOTE - (Someone told me that because I rooted the phone I cannot update my phone through AT&T servers)
Secondly my device from time to time restarts it self.
And sometimes the wifi stars connecting and disconnecting every few seconds.
Can anyone help me?
Thanks

Having root can stop the install.

The ATT updates can fail due to the device being rooted as stated by others here. Just as it has been recommended do a back up and a factory reset to see if it helps with your rebooting issues and wifi. Check your baseband under settings/about and if it ends with MDL i would recommend that you DO NOT update. The reason for this is that since you are rooted you can install ANY custom ROM on your phone, you can even install the latest google edition ROM 4.4.2. If you do the ATT updates and your baseband changes to MF3 or MK2 then you will be stuck with just limited ROMS and you will also be stuck with all the ATT/TW bloatware. Trust me 4.4.2 is soooo much better your phone will run alot faster and you will have the latest google version on your phone. I was on MDL and all the ATT updates failed on me and i just decided to install the google edition ROM and man oh man I LOVE IT!

You may not be able to flash 4.3 roms and above with no issues. Your bootloader is locked down and no custom kernel flashing either. Also, only TW roms. That said there is newer beta Safestrap 3.7.1? that is letting 4.3 TW roms flash. I think!
I am on an original phone and not up on Safestrap. Read all you can here about it. Threads will be in General and Q&A.

On MF3, your only option for a recovery is Safestrap 3.65 and you can only flash other 4.2.2 ROMS. Trying to use the updater in the GPE 4.2.2 ROM will possibly brick your phone. If you update to MK2 then you can have 4.3 ROMS but the 4.3 GPE ROM uses a different kernel and so you won't be able to use it.

Yes, but if anyone is asking for the record it's still in beta, only on Hashcode's goo.im, and if they're still on MF3 they should stay if they want GPE and check which ROMs are compatible in the Safestrap thread before going to MK2.

Yes it contains all the bloatware, another reason not to upgrade and flash custom roms.
Edit, it has not been mentioned yet but one you upgrade you can not go back to a previous firmware.

When I upgrade to MK2, does this mean I will need to perform factory reset and all my existing app will be gone or will the app remain on the phone even after the upgrade.
I will do the backup before the upgrade but at the moment when I connect the Phone to the PC, it would mot pick up so maybe I will need the latest software driver, is that correct? I have the same problem with Kies which does not recognise when phone is connected.
Any suggestion would be great.

Not always, most times a factory reset is needed to clear the phone of old apps and data. Root, is lost, but apps that require root can still be present which can become a problem when root is no longer available.

He's on mdl which allows a custom recovery and easy flashing of roms. If he upgrades to mk2, the latest, he'll lose that ability. Try this http://forum.xda-developers.com/showthread.php?p=47713264

Right, we have a custom recovery and an unlocked boot loader and I flashed an older build of that Google edition ROM, but he just really wants the ability to move his apps2sd. I didn't see a mention of the apps2sd feature in the change logs. Thanks for replying so quickly.

The NC1 .tar for the ATT I337 is not available. It was such a small update that a full odin .tar is unlikely.

Alright thank you , So if i root it and another update such as 4.4.3 i wouldn't be able to get a OTA update would i ?

It depends on the update....some OTA updates check every single system file to make certain you are completely stock( including unrooted). Others, like the NC1 update, only check some of the files.
The 4.4.3 update is supposed to be a minor bug fix(no UI changes) and may still flash successfully even if you are rooted but it is almost certain that you will lose root.
I suggest everyone hold off on taking the next ota update until some of us can evaluate it and determine our options (we say this all the time yet very few listen ).

Okay so the next update won't be like the Galaxy s5 Kit kat ? No difference in the Touch Wiz ? Just bug issues solved ? & Also so would you root your phone as of right now ? on NC1 If you were on it ?

I don't know for certain that we will not get the updated TouchWiz however I highly doubt it.
And I did root my phone with my NC1 100% stock rom and then unrooted once I had it set up the way I like it.
When the next ota comes out I plan on creating a safestrap flashable update zip to test and see if its rootable with towelroot and create a pre-rooted safestrap flashable 100% stock rom as a workaround if its not rootable.
