I am sure my answer has been posted before, but i couldn't find what i was looking for after scouring google and XDA for a few days now so my apologies in advance.
I have the ATT I337 s4 with 4.4.2 firmware and am trying to install liquidsmooth V3.2 but obviously its not working. I keep getting an error that states:
"E: signature could not be verified"
"E: whole package signature could not be verified"
And then the phone factory resets itself and reboots.
What I have done: Rooted the phone with towelroot, then installed supersu, disabled knox, and then installed busybox.
Some posts I read said that i need to use safestrap to install liquidsmooth, so i tried that as well, and it says the installation is successful, but the program state never changes to show "installed" and the button to reboot into recovery never gets activated.
I am not sure what I am doing wrong, but I think from what I have read that I need a custom boot loader in order to get the install to work, such as CWM, but then i run into other posts that say:
"NOTE – For AT&T/Verizon users with Android 4.3/4.4.2 or higher, you cannot use the LOKI method, you need to use SafeStrap Recovery to install custom ROMs, see How to Install Custom ROMs on AT&T/Verizon Galaxy S4 using SafeStrap instead!"
Im hoping someone can fill in the gaps that I am missing because it is getting annoying having my phone factory reset after every attempt and having to start over again, but its better than a brick lol.
Let me know what you think, and please help get me in the right direction
What firmware version are you on? Go to settings, more, about device and look at the last three characters of your build number.
Nvm, I read your firmware as 4.2.2. You're either on nb1 or nc1. Either case you'll need to use safestrap. See in the general forum index, all things at&t.... It'll have everything you need.
PS, you won't be able to install liquidsmooth on your device. Only touch wiz based roms

I've tried using several different guides published on XDA and other forums, and I still cannot get CM 10.1 to install correctly on my AT&T Galaxy S4. I have been able to successfully root the phone and install the latest version of TWRP (using the instructions here: http://forum.xda-developers.com/showthread.php?t=2262996). However, when I try to flash CM 10.1 using the file found here: http://wiki.cyanogenmod.org/w/Jflteatt_Info , it fails. After reboot, it loads the Samsung Custom screen for about 10 seconds, and then everything goes black. I have to pop the battery out to power off. Luckily, I was able to use Odin 3.07 to flash the phone back to its original firmware. I've tried to do this at least half a dozen times, but to no avail. Does anyone have an idea of what I could be doing wrong? I would greatly appreciate any help, or if someone could just point me in the right direction. Thanks.

I am in exactly same boat but right now I am using same custom recovery as you and afraid to do anything else. But I think here is what's going on. CM10.1 you're trying to install is not LOKID (LOKI is something to trick bootloader because our device bootloader is locked) So that LOKI thing should be on rom itself AND kernel. Our recovery does not auto-LOKI roms that's why you installing them and they're fail. So you need to install new recovery with AUTO-LOKI feature installed if you look in developer section you'll see. Now here is my question. How do I go from TWRP that been installed via GooManager to CWM - Auto-Loki edition ? Anyone 1.2.3.4 guide for us ?
Here are new Recovery that have AUTO-LOKI feature. IF your ROM/KERNEL already preLOKI (pre patched) it will still work it'll know rom pre-patched.
http://forum.xda-developers.com/showthread.php?t=2291956
So anyone can get quick guide how to move from TWRP to CWM from above ?
Finally got my ATT SG4 rooted and recovery installed. Downloaded Goldeneyerom, backed up, wipe/reset, and when i try to flash it fails immediately
downloading another ROM in the meantime but what has happened here? i swear i never get it right :/
and for the record i'm clueless here. I dont know what MK2 and NC1 and all that is, I just want to flash something that lets me bypass the load screen and has all the bloatware removed. Any link would be appreciated
Please be specific
What bootloader is your device using? What Firmware are you currently running? What Rom are you trying to flash? Did you verify the MD5 of the ROM you downloaded? Are you sure you are rooted? What custom recovery are you using?
Thread cleaned and moved.

bootloader is locked
stock mk2
any rom that will actually work
not sure how to verify the MD5
towelroot says im rooted
super user is installed
root checker says i have root access
using safetrap as recovery since its the only one i can use
hopefully that was enough info for you to be able to help me with the next step. I should this was going to be alittle easier, been at it two weeks now and i have basically just been doing everything the wrong way.
Are you using SafeStrap specific ROM?
My device needs Loki Doki. I've never had a SafeStrap device. I wonder if the ROM you're attempting to use doesn't work for your device type. Try using ROMs like http://forum.xda-developers.com/showthread.php?t=2468860 wich are made for devices uing SafeStrap. Most ROMs on here are de-bloated so whichever one you choose, it'll be better than the original one your phone came with.
Firmware/Radio shouldn't affect your phone's ability to install a ROM, just affects your performance (i.e. signal quality, etc.)
Like I've mentioned, I've yet to ever deal with SafeStrap so its a bit out of my league. Can anyone else offer up some advice?

alright i tried flashing that rom with safestrap and it also failed immediately
help!
I am not SafeStrap savvy either. But, with MK2, I "think" you can only flash 4.3 roms and may need the older SafeStrap. I would, if you haven't, get up on the SafeStrap thread and check out "All Things MK2 etc" thread. This isn't an easy phone to flash and some more research may save some headaches. I didn't catch your post count. You need 10 to post in Dev Section. Always wipe System along with Data and Caches before flashing rom. Assume those are available in SafeStrap recovery. You might want to upgrade to NB1/NC1.
You do need to check rom md5 after downloading with file manager like ES File Explorer. I use a Command Window and just drag downloaded rom to window. The md5 is basically a way to check that you got to your phone what the download site was suppose to send. It is a checksum. Roms don't always download correctly. However with all your failures, I doubt that is your problem. The md5, if available will be listed on thread OP page and/or download page. Also, try downloading to Internal, if you are not, and see if that helps.
A lot of this you can Google, as I did in the beginning. If all else fails go to the thread "No Stupid Questions" It is Stickied at top of Q&A and SafeStrap is currently toward bottom of first Q&A page. :good:
It's probably because you have safestrap version 3.71? If that's the case all the latest Roms require Safestrap 3.72 so try updating and see what happens

says 3.72 isnt for MK2. And when i tried it it won't even load into recovery. So i guess I can't use any KitKat roms.
SO now that the umpteenth problem is out of the way, while I'm downgrading back to 3.71 can anyone recommend a good 4.3 rom?

Oops, told you. Sorta. Would keep reading those related threads and go to the 4.3 ROM threads listed in All Things MK2 and read the OP and last 20 pages of thread to get a feel. The different SafeStraps are particular in how you flash Roms to them. So check that out too. As far as how the roms work, it will vary for each user. So, have a backup. Good Luck.

Well you're right on that part 3.72 isnt for MK2 BUT! after you get Safestrap 3.71 installed on MK2 you can use this method and flash this NC1 Rooted Rom in Safestrap Method 2 Post 3 to be exact http://forum.xda-developers.com/showthread.php?t=2730144 follow the instructions to a T and you will be on NC1 4.4.2 and once there you will have to download terminal emulator and type "su" then enter then "setenforce 0" (that changes you're SElinux status to Permissive instead of enforcing) because the safestrap 3.72 apk wont install properly once done with that download a busybox apk installer and reinstall busybox after that you should be good to go install safestrap 3.72 and then reboot into VIOLA

Daman you got two pieces of bad advice here.
1. Double check suggestions before doing them
2. That's done by reading thoroughly the threads I suggested till you understand enough not to get into trouble
Looks like trouble on Hyper also, that's why I am re-stressing study first. I want you to get it right the first time. SafeStrap is complicated untill you understand all of it--:good:

Go to the No Stupid Question thread in Q&A. And tell exactly where you are and ask for next step. Maybe odin back to stock and start over after some re-reading. jd is pretty good there with helping out on all kinds of issues. You generally won't get much help in the actual Dev thread. :good:

Well, I purchased an SGH-i337 with the hopes of running custom firmware. I got this device in November of 2013. It is now August, almost September of 2014, and I just was able to root my phone for the first time. Still unable, however, to remove all of those stupid AT&T apps that I NEVER USE.
Secondly, I tried to finally install a custom Rom on this phone, only to find out that no matter what I do, I cannot boot into CWM or TWRP recovery. I have searched and searched the forums, the internet, watched numerous (but apparently irrelevant) videos on how to do this, and can find nothing that actually works. I follow these steps to the letter, and keep finding something that I just can't get past.
Step 5: Boot into CWM... Nope, I get 3e
Step 6: Load TWRP with GooManager. Now I have no recovery mode.
Etc. Etc. Etc.
I am really at my wits end here with this process. I don't want to have a phone with all this junk on it, and I can't figure out how to get a custom rom loaded. I currently have UCUFNC1 loaded, and can root using http://towelroot.com/
Other than that I cannot find any "walkthrough" or "installation method" that actually works. If someone could help me with this, or point me toward one, it would be much appreciated.
The only way to get a custom recovery on an AT&T S4 is to have the MDL bootloader. Your phone is too new and or updated.
If you want a custom ROM, you have to use SafeStrap. With SS, you can only load ROMs that use the stock kernel.
Wish I could help more but I don't use SS.

Hello there!
I've successfully rooted my (Rogers) S5 Active / G870WVLU1ANH3 / kltevlactive using CF Auto Root, blowing my knox and all that, works great.
However, I'm now trying to flash either TWRP or CWM Philz for klte (which may have not been to smart come to think about that, but I recall reading it should work just fine) using Odin, and I can't get into recovery. Whenever I attempt to boot into recovery, I end up with "cannot do normal boot".
I recall reading a SafeStrap for G900 works for the G870, but I can't find the thread again, and don't want to just try and see what happens.
I've also tried flashing a recovery using either TWRP app and RomManager, I have yet to try Rashr, but since all the recoveries I've found are for klte, instead of kltevlactive, I'm slightly worried.
I'm not all that new to rooting, but I'm quite new (and upset ) at the Samsung realm, any chance you guys would know what could get me going with a custom recovery?
I also have a Xposed Framework installed, I read it could cause issues with SafeStrap, but I don't suppose it would affect flashing a rom from Odin/whatever else?
My SELinux on the phone claims to be "Enforcing", if that matters, perhaps.
Thanks!

Any luck on this? I've scoured the forums with no luck, although I see people mentioning they have it.
I am experiencing something similar. I have a rooted SM-G870W (Bell). I tried both TWRP and CWM recovery.
Every time I tried to go to recovery mode either via pressing button combo or from adb (adb reboot recovery),
my phone goes into download mode instead, I get "Downloading... Do not turn off target" screen.
Have you also experienced some weirdness with your rooted phone? On mine if I go into boot into recovery
(this is without custom recovery), do nothing but select reboot, I will get "System UI stopped working".
Or "unfortunately mtp application stopped" . I re-flashed the phone with the stock OEM ROM and I don't
get the issues I sated above.
BTW, how did you get xposed framework installed. Mine said "not yet compatible with Android SDK 21 "
Thanks

Hi There
I'm having the same issue but all they talk about here are 900 and we have G870W
If someone find any information and how to flash the 870 I would be greatfull
to them because all I could find on the internet pertains to the 900 this is infurating
and by the way any of you have that OEM button in developer?
I bet not again all I've been reading on S5 Active also mention about the OEM button
and this is total BS because we don't have a OEM button. If we can find
a site that could help use with our particular phone and not just the 900

Android Version: 4.4.2
Rom: XXUGNG2-SHOstock-i-v8.1
Bootloader: I337UCUAMDL
Recovery: TWRP 2.5.0.2
I've been installing Custom ROMs for a while on this phone and the previous phones I've had (Nexus One, Galaxy Skyrocket.) My S4 hasn't had issues installing them until more developers adopted Aurora Installers and now any ROMs that use them won't work. My phone goes into a boot loop and I need to restore my previous Nandroid backup. I thought that my TWRP might be the cause, but it looks like nowadays the only way to update TWRP is through the GOO Manager. Unfortunately for whatever reason that doesn't work properly and I can't figure out how to get it in any other way. So for a while I had this older ROM installed but now that we're well into Lollipop I decided to try another ROM (GOLDENEYE|XXUHOD7 LOLLiPOP TW|5.1.15), but again it had Aurora and failed, and this time it looks like it messed up my bootloader because now I have the unlock icon whenever I turn on my phone (I don't care much about that because my phone is well outside of warranty at this point, but I'd prefer it be removed)
So I was considering just using ODIN to revert all the way back and starting from scratch, but it looks like my phone will be bricked. So basically I'm at a standstill because I obviously don't want to brick my phone, but at the same time I'm not satisfied with my current ROM since it's quite long in the tooth and isn't even Lollipop based. Any help/suggestions would be greatly appreciated.
TIA
One thing you might try here, and another here.

There are flashable zips of TWRP floating around to update and the TWRP thread in our section says to use the TWRP Manager app on the Play Store. As far as using ODIN, you won't be bricked. The unlock icon shows up when it detects the system files aren't stock/root is in place. Your bootloader should still be in tact, and if you can still boot into recovery that confirms it. Either way, you just need to use a different method to update TWRP and you should be fine.
Well I feel like a f-ing nimrod..
I failed to mention in my description that when I first tried to install, not only did I get the Unlock icon, but I got the "Software not authorized by AT&T..." error message that prevented me from doing anything. However, I thought this was related to my phone being carrier locked. I found out later that my phone was unlocked a while ago so that wasn't it. Had I looked more closely at the error I would have seen that it was a Kernel error. Turns out I had to install a LOKI'd Kernel. Not exactly sure why, but that was the only one that worked. Now the new ROM is installed and I'm restoring my apps now.
If nothing else, I got my TWRP updated finally, so I like to think this wasn't all for naught. Thanks for the insight anyways. This was easier than doing an ODIN back and forth.
This is because you're on the MDL bootloader. You need to search the forums for your phone in regard to the MDL bootloader and loki'd ROMs. When you see the "software not authorized. .." message, it just means you need to flash a loki'd kernel for your device. Search for Jeeboo's Recovery and Kernel and you should be right a rain. Good luck.
Edit: I was half awake when I tried to answer your question, and somehow missed that you had discovered the loki'd kernel already. The reason for this is because the MDL bootloader is susceptible to the loki exploit, which for all intents and purposes is the equivalent of unlocking the bootloader. I've been using Jeeboo's recovery for a year or so and never had an issue with any ROM I tried. The kernel cones in handy for those that need a loki'd kernel. There's a ton of easy to find info in the forums to help you get a better understanding of the MDL and how loki applies to it.
