[Q] Beginner mess up. not sure what to do next

hello, so, ive had the s4 (att) for a while and i have a small problem, i rooted it (and confirmed the root with rootchecker) and at some point decided to try to install a custom mod on it. issue is i am on MF3 and read of all the dangers and kinda stopped. but i stopped after attempting to get CWM on the phone using rom manager (from teh google play store) now when all this happened it was months ago and i had just started on android exploits and the dangers scared me off, i used a jailbroken and unlocked iphone before.
needless to say currently i want to get cyanogenmod on the phone. its rooted, but im not sure what to do next. ive been reading materials for about 2 days now. threads keep contradicting eachother some say use loki and odin others say you cant because its gonna brick mf3.
looking for a quick answer on what exactly i need to get a custom rom installed. the guides here are great but again most say mf3 will be bricked while others say otherwise.
also currently the phone randomly displays a "custom" boot screen right after bootup. sometime it does sometime it doesnt. im guessing from teh CWM. but not sure.
help.

I read this and i'm not sure in what stage you are? What firmware you are on ( asume stock rooted MF3). Did you phone bootup all the way or not? All i can help is just start fresh from here: http://forum.xda-developers.com/showthread.php?t=2502003 if you on MF3. If you not on MDL just go to sammobile find firmware and flash with odin.
After you back to stock firmware root you phone (look for correct metod on firmware you have) install SafeStrip for MF3 or CMW for MDL ( do not install CMW if you on MF3) SafeStrip post here http://forum.xda-developers.com/showthread.php?t=2448925 and more info here :http://forum.xda-developers.com/showthread.php?t=2428254.

well the short version is this
bought phone (it auto updated to mf3)
rooted phone while on mf3
installed rom manager off the play store, which installed CWM.
i uninstalled rom manager but im more than sure that CWM stayed.
currently i want to start over, hopefully flash the phone back to stock and re-root it and try again using a better method (like safestrap)
so all i have to do is get odin + mf3 pda/csc/phone/modem files and flash the phone right? then its gonna be back to stock rom. so i will have to reroot it and try again...
will this also reset the flash counter?

So from what I read, you're not in a great position. MF3 CANNOT have a custom recovery, sure you can install one like you did but it won't work. That being said what you mentioned should work, flashing MF3 via ODIN. After that, root it and install SafeStrap, it's the only option for MF3 (currently no options for the latest firmware AFAIK).
Link to Odin thread:
http://forum.xda-developers.com/showthread.php?t=2504311
read the entirety of it, it's only 5 pages long.
http://forum.xda-developers.com/showthread.php?t=2314494
Read post 2 thoroughly, it has lots of good information. IGNORE THE FIRST POST, it doesn't apply to your phone
Lastly if you don't want the phone to update itself, what I did was install Titanium backup and froze the following apps:
1. AT&T Software update Vxx_x_xxxx_x_x
2. FWUpgrade x.x.x
3. LocalFOTA vx_xxxx_x_x
as for the flash counter, I'm not sure. I hope this helps a little.

What i would suggest is to odin bak to UCUAMDL and then use casual to root back.
Then you will have TWRP recovery and can flash any rom (loki'd) , Also keep in mind never do a data format using twrp.

[Q] Help! Error Updating from MJA to MK2 on Sim Unlocked Phone

Hi,
I have looked all over this website and others for the solution to my problem. If there is a thread for this then I am sorry, but I couldnt find it.
I recently moved from the US to Mexico. I took my SPH-L720 to a phone technician to get my SIM unlocked and am now using it on the Iusacell network. Everything was working fine until I tried to install the MK2 update. The OTA update downloaded just fine, but when it is installing it gets about halfway and then displays a dead Android robot with a red triangle and an exclamation mark and the word "Error".
I do not believe that the phone technician rooted my phone. I think he flashed my modem to MDC. My build number is MJA. My software version is MDC.
Can anybody help me? My phone seems quirky after the MJA update, especially battery life. I am hoping MK2 will fix everything. Also, I have a Mac and not a PC.

Sounds like there is a whole lot going on with your phone setup with so many inconsistancies.
If the Modem(baseband) is MDC - which it woul probably have had to be to do the SIM unlock stuff, and your build is MJA but your software version is MDC you've got a lot of stuff to look at.
How did the tech flash your phone? PC Odin? or via a zip/recovery. If it was flashed via a custom recovery (meaning you have one on your phone) then the OTA will fail/error. Same thing with a custom kernel - failure of OTA. Stock boot/kernels are required for OTAs to work.
The latest update is actually MK2 and not MJA by the way.
You can flash a .tar using Heimdal. Sammobile has the full MK2 one here.
BUT you'll probably need to do some fancy stuff with you APNs to get it to work on your current network - time to see tech who helped you again.

Thanks for replying so quickly! I am very new to all of this stuff. If I flash the .tar file will that fix everything? Do I need to root my phone to flash the .tar file? Also, will my SIM remain unlocked or will it relock?
As for the APN, I think I already know all of the necessary info to input because when the tech unlocked the SIM he didn't input the APN info.
BY the way I know MK2 is the latest build and that is why I am trying to update from MJA to MK2. I'm sorry if I didn't make that clear in the OP.

Sorry, I also forgot to mention that I don't know if the technician flashed it with Odin or a zip/recovery because I left my phone there for a few hours. Is there a way to check?

See if you have a custom recovery.
Boot to recovery - Power off. Then Power on+Volume Up+Home button and see if something like CWM, TWRP or Philz recovery loads.
If it is just Spring/Samsung recovery then he flashed the modem via Odin and not a custom recovery. Either way just power off to boot again.

It is the stock Samsung recovery. I guess he used Odin.

[Q] "Downloading.... Do not turn off target!" after TWRP

Can I get a little help here? I have a rooted, otherwise stock i337 that I just used the TWRP root app. I wanted to make a backup of my phone before I flashed a new rom. It downloaded jflteatt and I verified and installed it to /dev/block/mmcblk0p21. then i tried to make a backup, and i'm stuck at "Downloading.... do not turn off target!!!" In the upper left corner there's a "Could not do normal boot. ODIN Mode.
I found the post "[GUIDE] How to Unbrick your AT&T S4 I337 OTA UCUAMF3" but am hesitant to use it, as I am not sure that is what I need to do. I also found some other similar posts, but for different devices so I am again hesitant to rely on those.
I tried pressing home, power and volume down, but it just resets back to this screen. Also, I originally posted this request on the TWRP page, but I think it should be here. If so, I will delete it there.
Please help?

@kamikazees
If you could give more detail that would also help other to help u....such as what firmware that u are running before bricked...... well seem to me that u are either MF3 or MK2 firmware and u installed TWRP ...... u can only install safestrap recovery if u are on MF3 or MK2 firmware. ....Follow my thread http://forum.xda-developers.com/showthread.php?t=2621279 it should get u back to MK2 firmware. .....goodluck
Swyped From MK2 Dark Venom SS Edition

Thank you for the quick response. I have a small update since my first post. I found a poster in another section who got his phone rebooted by trying to send it to download mode, then cancelling out. I did that (pressing power, home and vol down), then when the phone "buzzed" I let off those keys and pressed them again. The phone rebooted, apparently normally.
So now I can check my firmware. Checking firmware is on the "baseband version" right? If so, then that info on my phone is I337UCUEMK2," which I guess is the MK2 firmware.
I deleted the TWRP app, but I'm not sure now if I've even got a recovery (if TWRP failed to install, maybe I'm still on stock?). Do I need to go ahead do the full ODIN tar file unbrick from where I am now? The phone appears to be operating normally.
If not, should I just go ahead and install safestrap recovery? I am trying to eventually get rid of all the bloated samsung junk and get to CM or another ROM. The S4 seems a bit more touchy than some of my previous phones.

Your stock recovery is probably broken, and so it would be best to at least reflash the stock recovery. However, you should be just fine if you want to only install Safestrap and leave recovery broken. I just wouldn't recommend that.

Ok, I want to fix the recovery. Can I use ODIN for that? One post I found said I cannot: http://forum.xda-developers.com/showthread.php?t=2576291. It was several months ago, however, so I am not sure if it still holds true.
If I can use ODIN, I see that the stock recovery file is in ted77usa's post #3: http://forum.xda-developers.com/showthread.php?t=2621279. After putting my phone in download mode and connecting it to ODIN, in which slot would I put that file? Some older posts say to put it in the PDA slot, which appears to be the AP slot.
Thanks for your patience. I really don't want to mess this up again.

The first one is in img format and won't work through ODIN, but you can use those commands from terminal emulator to flash it if you download it. Otherwise, the TAR files do work just fine.

If you are rooted and can actually boot the phone then I would install Safestrap for MK2 and install TWRP 3.71 to use as the recovery. I've been using Safestrap and TWRP since I was on MF3. I have also successfully flashed the tar files through Odin to get to MK2 with no problems. If you are rooted then its a really good idea to use Safestrap with TWRP for a recovery. Afterward you can find a list of compatible roms that are specific for Touchwiz on MK2 that for the most part are pretty stable. The stock recovery on this phone is pretty much useless.

This is exactly what I did. I flashed the stock recovery in Odin (yes, it goes in the AP slot), which fixed my first problem. Then I installed Safestrap, then made a ROM slot and installed Goldeneye v. 21 (the 4.3 version for MK2). That removed all of the AT&T bloat (yay), and I did not have to flash the MK2 kernel (which I think would also have gone in the AP slot) because it has it already.
Then I flashed the GE add-on that removed a bunch of Samsung bloat (yay #2). Rebooted and turned off the rest of the Samsung stuff I didn't want. Got the phone up and running beautifully.
What a picky phone! The locked bootloader really causes a lot of trouble to inexperienced flashers like me. I unfortunately have about 5gb of "wasted" space because I understand I cannot flash over the "stock" rom, but I am at least running another ROM that I chose. My phone, my choice. Shame on Samsung!
Thank you very much!

There is actually a way to flash a rom to the stock slot, but I haven't done it. Somewhere in the Safestrap threads explains how to do it. I think you can even get it back to normal if you change your mind.

Well, I feel stupid, I never had the phone in download mode so that is the reason it failed. This is what hapopens when yourn addicted to phones and go thru different ones every coupkle of months. I managed to fllash and downgrade but lost both data and Wifi. I searched but could not figure out why I could not get data and wifi to work on MK2.I rooted and all but could not get data or Wifi to work. So, I Odined back to NB1 and have both data and wifi working. I'm not sure why I lost it. I really want to be able to get MK2 back up and running but I'm at a loss. Could use some help with this.

Do a data factory reset from recovery after you flah thru Odin, it should get you out of the bootloop. I had the same thing and after I did the reset it booted ok. Only issues is that I loast data and wifi on MK2.

I337 AT&T S4 - Return to Stock (No WiFi)

I recently bit off more than I could chew with my S4 (I337). I had 4.4.2 KitKat on it and wanted to root it to add teathering. I decided thought there was no root for 4.4.2 so I thought I would try downgrading to 4.3 then root. This seemed best because I didn't like the way the SD card is handled in 4.4.2 and some of my apps (like ftp server) have stopped working.
When I got the phone back up from flashing with Odin it says it has version 4.3. My WiFi will not turn on. If I slide the switch to on it slides right back to off and the phone tells me that an operation was block (can't remember the full verbage. I have installed and attempted to install many things on my phone. I have used recovery mode / Odin3 and Kies (Kies doesn't allow much).
At this point I just would like to get my phone back to 4.4.2 with the WiFi working. Then I can restore my backup and be back to square one with a lesson learned.
I have an I337 that currently thinks it has version 4.3 on it. The baseband version is I337UCUFNC1 currently. The build number is JSS15J.I337UCUEMK2.
If anyone can help I would greatly appreciate it. I have read and tried many things over a two day period and finally decided to ask for help.

Had this issue before on my Bell Canada S4, but don't recall exact way to fix it.
Think the solution was to find an older (might be newer) stock. I think I used a different version like the Telus Canada version as well and it ended up working. Then you update through kies after.

Wifi does not work because of the modem/kernel mismatch, i.e. MDB modem and MK2 kernel. Not sure what your goal was when you began flashing your phone but since you fortunately did not flash teh MK2 bootloader you are still able to locate the MDB full odin tar and flash back to stock which will resolve your issue.

It depends on what you are trying to accomplish. Are you trying to upgrade to MK2 or higher while maintaining your unlocked MDB bootloader?

If you don't care about losing your MDB unlocked bootloader you can get to the latest kitkat firmware by flashing the NB1 full odin tar from here:
http://forum.xda-developers.com/showthread.php?t=2674223, then once flashing is complete go to settings/more/about phone/software update then take the ota update to NC1 which is the latest kitkat version for our phone.
But what I would do is keep your unlocked MDB bootloader and since you already flashed the MK2 AP file you can get your phone running well again by flashing the MK2 modem: https://mega.co.nz/#!pwESna5I!YK7EKG37xXIG1ReB-Z-mfSMoXNkXQ9t2EdMK9ofgJKg
From there, there are still a number of options available to get to kitkat which I won't get into.

I recently bit off more than I could chew with my S4 (I337). I had 4.4.2 KitKat on it and wanted to root it to add teathering. I decided thought there was no root for 4.4.2 so I thought I would try downgrading to 4.3 then root. This seemed best because I didn't like the way the SD card is handled in 4.4.2 and some of my apps (like ftp server) have stopped working.
When I got the phone back up from flashing with Odin it says it has version 4.3. My WiFi will not turn on. If I slide the switch to on it slides right back to off and the phone tells me that an operation was block (can't remember the full verbage. I have installed and attempted to install many things on my phone. I have used recovery mode / Odin3 and Kies (Kies doesn't allow much).
At this point I just would like to get my phone back to 4.4.2 with the WiFi working. Then I can restore my backup and be back to square one with a lesson learned.
I have an I337 that currently thinks it has version 4.3 on it. The baseband version is I337UCUFNC1 currently. The build number is JSS15J.I337UCUEMK2.
If anyone can help I would greatly appreciate it. I have read and tried many things over a two day period and finally decided to ask for help.

I told you not to drink and root.

Quite a few steps in those threads but I got it working again. I really appreciate all the help/advice given. Now to decide if I want to remove the safestrap screen on boot. Again Thanks.

excited to give this a try. rooted with the downgrade method a couple months ago but left with a non-wifi device. my only issue is that the thread says it's for I337UCUFNC1 and our devices are on jss15j.i337ucuemk2. will this fix still work? I've heard on other threads on the subject that the modem kernel doesn't match up with the flashed rom or build number or something.

Do you already fix it??? cause i have the same problem

Same question, different thread!
Not even an hour ago did I answer the same question in a different thread: How do I get WiFi working on my S4?
Well here you go.
My original answer: http://forum.xda-developers.com/gal...-4-4-2-nb1-t2850878/post54978150#post54978150
The problem is, in order to get WiFi working, you need to install the NB1 modules, but to do that, you need to install Safestrap. However, you can not install Safestrap because the app keeps closing on you. There is a simple fix to this, which I will explain later. For now, just read this WHOLE post BEFORE you do anything, and keep in mind that I am NOT held liable if you mess up your phone. Use this at your own risk.
1.) Root your phone
If you're already rooted with something like SuperSU or Superuser, skip this. If not, read ahead. Download and install the Towelroot APK file attached to this post, open it, and click 'make it ra1n'. If your phone didn't reboot, now you have root (they need to trademark that). Now, down below, I also included the APK for SuperSU. Download and install it. Now open it. When you open it, let it install the 'Normal' way, not via the 'TWRP/CWM' way. Also, when it asks you to disable KNOX, say yes, wait a couple of minutes (it will still be loading) and reboot your phone. Open up SuperSU again, click 'Yes' to disable KNOX again, and now you have a good base to start from.
2.) Install Safestrap AFTER fixing the error
The error your are getting is easily fixed. Go to the Play Store and install 'SELinux Mode Changer'. Open it, grant it root access, and change the mode to 'Permissive'. Now, open up Safestrap again (you mentioned you already installed it), and it shouldn't force close. Click 'Install', and if the 'Reboot to Recovery' option below is not grayed out after that then it worked.
3.) Download and install the NB1 modules
On your phone, download the included NB1 modules ZIP file I attached for you, and once that is done you need to reboot. After the Galaxy S4 logo, you'll see a screen that says 'SAFESTRAP: DISABLED' and there will be a little robot. TIP: To enter Safestrap, press the menu button (physical, hardware key) under 'Recovery' at that screen. To continue to Android, press the back key (again, physical) under the 'System' tab. For now, press the menu button under 'Recovery'. Now, click 'Install' which should be in red, click 'Add zips', and navigate to your Downloads folder. Now click on the NB1 modules ZIP you just downloaded. Swipe to install, and reboot. This time, hit the back key under 'System'.
All done!
Now, Android should (and will) boot up, and you'll have working WiFi! If, for some odd reason, you don't have WiFi- do NOT panic! Just search around for the MF3 modules and flash those! All is good, all is good. A lot of this guide was taken from my post about my personal method of SIM unlocking the AT&T Galaxy S4 without the dialer codes or an AT&T SIM. It was just modified a little to work for you.
Remember, hit thanks!

Those are my exact words. Also, the attached files (NB1 modules, SuperSU, Towelroot, etc.) can be found attached to my post in the link above. Have a good night, and best of luck! :good::good::good:
