[Q] return to stock recovery?

I would like to update to mf3 but after doing the ota update it reboots to recovery but I now have twrp instead of the required stock recovery...
After doing a lot of searching the only solution I found was to flash the official firmware with odin, but I'm assuming I will have to do a factory reset after this?
Is it possible to replace twrp with the stock recovery without having to do a factory reset or is there another way to get the mf3 update with twrp? (I'd rather not have to re-install all my apps and settings)
I hope my questions make sense its late and I'm tired.

There is always a risk of screwing something up...so read the thread, follow the directions, and decide if you want to take the risk..it's your decision.

Why not just flash a sweet custom rom like omega v9.0? That's the best thing about a custom recovery. It makes it easy to back up your current content and then try out a wide variety of mods and roms.
It's kinda counter productive to flash a stock recovery when you are trying to mod or customize your phone.
Odin is the cats butthole when trying to return to stock. Also, read the poop out of these threads... somebody has done what you want to do already so most things can be resolved with the solutions others have presented.

The OP said he wants to update to MF3. I can't figure out why anyone would willingly do so either, but it is his decision. Personally I would also just flash one of the MF3 ROMs or International updated ROMs and still have the ability to use custom recovery with the benefits (I don't really think there are any) of MF3.

This should work. When you type the command make sure that the block number ( mmcblk0p21) is correct. Any mistake there and you will get a $600 paperweight

This is correct, but it has nothing to do with the OP's request.

I read this hole page and u quoted the op wanted to update to mf3 so I just reassured the op that there is a root method for it .I do apologize to the op

Thanks for all the replies.
I wanted to update to mf3 because isn't it a newer modem? I was waiting until root was possible which now there is a method for mf3.

thanks god did not turn my cell into a $600 paperweight :laugh: ... the process worked, but, when I try to do a factory recovery a sign from ATT says, in the top:
Secure Fail: Kernel
and a yellow exclamation with the following message: "System software not authorized by AT&T has been found on your phone. Please turn off your phone and go to the nearest AT&T store for help."
has anyone seen this?

You can flash your recovery with fastboot command:
Code:
fastboot flash recovery /path/to/revocery.img

I ended up just flashing the modem it seemed to be the safest option

Flashed wrong twrp...

Ok... I have been reading way to much today, to the point i did something rather noobish.
Was in the dev section TWRP thread specifically looking to downgrade fron 2.6 to 2.5, saw the last post where someone posted a dropbox link of 2.5. Thought "how convenient" and flashed. But the zip was for another model number, now i cant get into my recovery.
Odin flash of the stock image is always an option. But one that I would prefer to avoid it if at all possible. I was hoping that someone else out there was well... as stupid as I am, and maybe had some advice?
Is there any possibility that goo manager will simply over right the wrong recovery image with the proper?
Or is it by any chance possible to simply flash the TWRP ZIP with Odin?
Any thoughts would be greatly appreciated, and I already know that I'm a burnout lol.

Just flash the 2.5 twrp zip in twrp. It'll down grade

Goo should over write it, and just to make sure ..you have the i337m -Non att variant. Youll have to see if anybody has a non loki version if twrp 2.5

Yeah, just finished a backup/restore after goo re installed 2.6.
Everything seems fine. Just with so many "brick" threads on here wanted to be careful.

The bricks revolve mostly around the newest update that locks the boot loader on the at&t s4. On the m non at&ti believe you just need a non Loki kernel but I am not positive.

If it's I337m or M919, Loki or not, it doesn't matter...

My phone is bootloader unlocked from the start from what i understand its the Canadian Rogers varient.
Im just now after reading countless threads wraping my head round this device. Its way more complex of a situation then the note 2 (previous phone).
My understanding is that we stay away from anything loki'd.
2 days in and im still not comfortable flashing any rom 4.2 or 4.3 lol. Another day or two of reading :-\

Ponder that, a canuck is less subject to tyranny? Your bootloader isn't locked? NICE! AT&T has degenerated from American Telephone and Telegraph into a globalized melting pot of greed and required upgrade costs and technical support that uses broken English spoken by people in India. You Canadians luck out this time!
I jumped in with motochopper to get root back in May and had the AT&T Software update service frozen with Titanium Backup back in June, I was so lucky to be "on top of it" by reading this forum. I used "Casual" to obtain TWRP 2.5.0.2 a custom recovery. I've never seen it so easy. After burning an image 3.56 GB of my stock firmware, I have since deleted it from my handset and replaced it with a nandroid of my daily driver here because GoldenEye is flawless. I saved a copy of the stock firmware on my desktop computer just in case, but I doubt I'll ever flash it and all of it's horrendous bloatware.
So I'm a happy camper, that only suffers the jone'sen for a fix as a "flash junkie". I will try CyanogenMod on this S4 after they iron the kinks out.

Looks like you're ok now?
FYI for anyone else in similar situation, ROM Toolbox Pro can download and install recoveries as well. It can access TWRP as well as CWM recoveries. A bonus for TWRP, it detects 2.5.0.2 as latest (avoid the occasional Teamwin splash screen hang with 2.6)!
I used this method to downgrade from 2.6 to 2.5.0.2. :good:

Word of warning, why upgrade from a working twrp 2.5.0.2, when it works flawless? Sometimes upgrading to a newer, is not always the best...look at the XDA app....yikes...

You're very welcome! I initially had TWRP 2.6 installed via rooting procedure (one-click method) and recently had ROM Toolbox flash TWRP 2.5.0.2 over it. No probs. Did full nandroid after it.

Wrong twrp flashed
Dear friend wrong twrp for my device I'm not able to go to the boot menu, how can i get rid of this, help me please. I've my stack memory and kernel already backup in my device memory.

The phone is an att i337? If it is, I assume the bootloader is unlocked since you were able like to flash a custom recovery.

i have no twrp AND I am stuck in boot loop...............................what will I do

Boot into download mode and confirm the phone's model number. Then flash a stock ROM from sammobile.com with Odin to get the phone back to stock.

Galaxy S4 Recovery mode not working

So, first, I'm running the stock 4.2.2 rooted on the ATT SGH-I337.
I installed ROM manager shortly after the root, and recently downloaded CM 10.1.3 for the att model of my phone. However, I couldn't find it in the recovery system to flash it. So, I install goomanager and flash over to TWRP, thinking maybe TWRP's easier interface will help me to find it. I reboot into recovery, and if I attempt to enter recovery mode, it gets stuck on the "Downlaoding, do not turn off target" screen. So, I re-flash CWM back on it, and reboot to recovery, and get stuck on that same screen again. If I just boot it, it's fine, jumps right back into 4.2.2 TouchWiz rooted. However, as you probably know, I can't install a ROM without recovery mode, and stock TouchWiz is poo.
I'd like to get CM running asap, although I'm just glad my phone still RUNS for now (my experience installing CM on my S3 was a NIGHTMARE).
So yea, any reason I would be getting stuck on that screen and unable to enter recovery? Like I said, I'd like to have CM as soon as I can.
Also, if someone can link me to a guide to install through CWM w\o needing a computer, that'd be wonderful. Thanks!

I'm assuming you're running on the MF3 build version. Read up before you brick your device. Your only option for a custom recovery is safestrap. Come on people.
Cheers.

You never saw twrp. You saw the stock recovery. Mf3 won't allow a custom recovery.
Edit, you did see an i337 in the you tube vids, but it had mdl or mdb firmware. You can put a custom recovery on with them. Unfortunately it's not possible to downgrade the firmware.

And also, I did, in fact, read past rooting, and found several people running CWM and TWRP fine, so I figured it would work. Now maybe they didn't have MF3,and I wasn't paying extremely close attention, but I'm pretty sure there were some on the same model and firmware as I am.

So, at this point, it's a waiting game for someone to find out how to put a recovery mode on an MF3 firmware, is what you're telling me?
Also, I may have been in stock. I don't remember EXACTLY what clockwork looked like. I just know it wouldn't let me select the gapps and CM files,which is why I tried TWRP. Though I did have CWM recovery flashed when I booted it into recovery those several times.

Dude you never booted CWM. That was MF3s stock recovery. MF3 does not allow any custom recovery but Safestrap.

You need to read before doing more with recovery and ROMs. You can't use CWM on MK2, only safestrap. Loki doesn't work on MK2 either and safestrap doesn't flash kernels. You probably had a bad download that didn't flash right and your system probably got wiped if it's not going past the splash screen. Go flash the MK2 TAR files, they're in the General section.

[Q] Bricked i337 -- URGENT

Hi everyone,
I am new to android mods and such and I may very well sound like an idiot. However, even though I know little to nothing of what I am talking about I am in dire need of help. I never did any heavy modifications like custom ROMS but I merely rooted it and installed some tweaks via the xda installer. After toying around with one of the tweaks I seemed to cause an annoying random reboot which would happen when I would sometimes go to unlock my phone. Fine, I could deal with a few reboots here and there. However, my phone recently got stuck on the AT&T loading emblem and stood in my pocket for 2 hours draining a lot of battery and has not been resolved since. I am unable to enter safe mode and I tried a few guides to flash it to stock but I honestly have NO IDEA what I am doing. I am aimlessly following guides here but there is so much variability therefore I feel as if I would have the most success with personalized help.
What do I do? Please use simplified terms along with (relatively) full steps. For example, if I were to flash something I would go into recovery mode with home + vol up button factory reset, and the AT&T logo would still be there, frozen.
Things I have tried but have probably done wrong:
Factory reset
Install custom ROM
All and ANY help is appreciated at this point, I am desperate.
Thank you,
Suprr
Also, my ultimate goal is to install http://forum.xda-developers.com/showthread.php?t=2520418 this mod, or at the very least get the stock ROM working so my phone is usable.

I am assuming that you havent yet taken the OTA update to NB1 and your base is MK2. Or, do you have a MDB/MDL bootloader?
If MK2: You have to flash the full stock Mk2 firmware using odin. Download the "Full odin tar files" from the All things ATT thread
if MDB/MDL: Download the stock firmware from sammobile and flash using Odin.

He must have determined you are not on mdl/mdl firmware. Those firmwares would allow you to easily flash custom roms, nb1 is not as easy and limited to touch wiz based roms. Do you know if you had a custom recovery, twrp or cwm?

He must have determined you are not on mdl/mdl firmware. Those firmwares would allow you to easily flash custom roms, nb1 is not as easy and limited to touch wiz based roms. Do you know if you had a custom recovery, twrp or cwm?

To be frank, I have not a clue of what any of those are.

Alright, then the link you posted to the nb1 firmware should be ok for you to flash in Odin

I am flashing it right now. Let's hope it works.
EDIT:
Flashed the full tar version for mk2 to no avail via Odin

Flashing the MK2 full tar file from here in Odin 1.85 says it was successful (green box) and when I went to restart the phone it was still stuck on the AT&T logo.
I flashed from this thread and this line:

To return to factory stock MK2 flash the I337_MK2_Full_Odin tar

Boot into recovery and do a factory reset. That should get you past the bootloop
Ps, the first boot is going to take longer than normal. Give it a good 10 minutes

You're on mk2 firmware now. You'll need to root it using safe root and then put safestrap on in order to flash that rom. Look in the general forum for index, all thing mk2 and nb1. There's a lot of info there so read it carefully
