Hello XDA. I am going to unroot and return to stock firmware and recovery as i would like to update the phone through samsung kies. As i understand i need to update the boot loader and modem. I then plan to reroot and install ktoonz recovery and get a newer rom. I have an SM-g900w8 (telus) currently running x-note NE2 software version 3 i belive and ktoonz 08.04.2014 kernel with twrp 2.8.0.0. I rooted the phone 3 days after i got it and never took a samsung update. I am just curious as to weather i need to revert to stock recovery before i flash the stock firmware. I made a brick out of my S2X trying to revert to stock so i am a little gun shy. Also wondering if this whole coarse of action is advisable and worth the trouble. If there are any known issues with rooting and flashing after samsungs latest updates. Also if anyone can provide or point my toward the stock firmware for a telus sm-g900w8 that would be great as i cant seem to find a reasonable place to download it. i apologize for not doing more reading and research but i just spent 6 months away from home working so i am trying to catch up. Thanks again XDA any help info or criticisms are appreciated .

Hi Guys,
I stupidly got excited and installed the official Lollipop (S5 on THREE UK network) update when i was notified.
BUT...
I want to go back to KitKat as i preferred it (i wont go into reasons why)
Is there a downgrade path for me, either officially or unofficially?> I dont think there is at the moment.
Thanks guys!
Yep, this forum is literally packed with instructions on how to do it, a simple search will bring up what you need
hi thanks, i thought with the new protected bootloader i didnt think it possible.
this is what i read:
Note: The G900FXXU1BNL9 Android 5.0 Lollipop update comes with a protected bootloader it is clearly emphasize that the “SE for Android Status – Enforcing” that might cause issues when you try to downgrade to the old software updates. This also applies if you are planning into rooting and installs any custom recovery and any unsigned firmware once you are on Android 5.0 Lollipop , so please be aware with that.

Yesterday I tried out AllianceROM 6.0 and a few hours ago I went back to 4.4.2 'cause I liked it better than Lollipop. Here's what I did :
1. Enter Download Mode and flash STOCK 4.4.2 KitKat firmware in Odin (I used 3.10.6) and let it start booting.
2. It won't boot, this is normal (I panicked when this happened though ).
3. Go to recovery and factory reset/wipe data your phone.
4. Now hit reboot in recovery and your phone will boot up again (YAY :sun.
5. OPTIONAL : If you've made a nandroid backup before going to 5.0 you can now flash TWRP and restore it over your STOCK 4.4.2 KitKat firmware.
Hope I helped Let me know if it works out for you!
SUCCESS!!!
All sorted.
The hardest part was finding a link to the rom. sammobile kept giving me a gateway 502 error.
im now back to kitkat, AND no THREE UK rubbish.

New to the I337. AT&T with NC1. Android 4.4.2. Stock ROM with the 3.4.0-1125940 kernel. Rooted, SE Linux permissive, Safestrap installed. Compared to other phones I have owned, rooted and installed custom ROMS for this one is way more complex.
Today I tried to Safestrap flash a couple of different ROM's- the Goole Play edition (jflte GPE) and the Lollipop 5.1 ROM 2015061jflte both times using Safestrap. Neither worked. In the case of the Google Play edition, it wanted to install a new kernel as well, I tried with the recommended kernel on the install GUI (wow an install GUI on Android). Both times stuck in a boot loop. I ended up using for the second time, the excellent information here
http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642
to get back to stock NC1 (thanks again guut13 for the excellent guide and links to resources) and restored via Safestrap the present stock configuration.
My questions are as follows (I am posting this after a LOT of reading here)
1)Can I use LokiDoki ? I understand it resolves problems with the locked boot loader where one can flash pretty much any S4 ROM on the I337.Is this true?
2) I wanted to give the two ROMS I mentioned today a try. Neither worked although I followed the instructions carefully (wipe, install and reboot). I also would like to try the Phoenix ROM. Is it compatible with Safestrap? Are the two I tried today compatible with Safestrap?
3) I am on 4.4.2. I understand that 4.4.4 is out there as well as 5 but when I check either via Kies or OTA I am told this is the latest firmware for my phone. Any way to update this?
As I said earlier this phone is a lot more complex from a modding standpoint than any other I have experience with. I am unclear on which ROM's will work with the NC1. Before I knew about Safestrap and the boot loader problem I tried installing TWERP and ended up having to rebuild things with guut13's excellent thread.
With NC1 am I stuck on the stock ROM ? Can kernels be updated on NC1 using LokiDoki?
Any light or advice to be shed on my confusion wold be very much appreciated.

Loki doki is not an option for you, and you can only install tw based roms.

Thanks for the link. Have seen this thread. So I am on 4.4.2. So can I flash a 5.x ROM on the phone provided its TW --or does the phone have to be updated via OTH or another method to 5.x first? Or am I stuck on the ROMS specifically available on 4.4.2?
Thanks again very much for your interest and the link. Wish I had shopped more carefully and bought a non AT&T phone, one of the 5xxx models but I couldn't find anything other than the AT&T ones here in Ecuador.

That will get you to 5.0.1. You can flash the lollipop roms after that.
I wish I had known more before I bought my phone too. Live and learn, I'm about do for an upgrade though. Good luck.

Again many kind thanks for the help. This is the most complicated chain of BS to go through just to update a ROM thanks to the locked boot loader I have ever seen..... however you and others here deserve a lot of credit for finding workarounds...... the phone has been made needlessly complex with the BL and efforts by Google and AT&T to "protect" their turf and monetise the user. I would upgrade today were I not in Ecuador where everything costs double what it does in the US. The phone thief crop here is thick- this is the fourth phone in 2 years although the Galaxy Grand Prime I bought after the last robbery I still have. Broke the screen on that one and it was repaired improperly, I get a blank white screen on startup so can't get into recovery so its worthless to me for what I want it for..... so I have the S4 AT&T. Ah well.
Many thanks and enough of my *****ing.

I just got the Verizon variant of the Galaxy S5 (SM-G900V). I rooted it very easily using odin without tripping knox; that was easy.
I then began looking for ROMs; which for this phone, isn't easy with the locked bootloaders.
I came across a custom ROM, forgot off the top of my head but may go back to retry loading it.
Because these devices have locked bootloaders, any ROM flashed to it will need to have a separate bootloader flashed as well. The aforementioned ROM had one and I understood why, but after I odin flashed the new bootloader, i kept getting a black screen. OK no biggie, factory flash, re-root look for another ROM, except this time, I'm looking for a pre -rooted factory ROM. I came across a lollipop one, 0A8, was hoping for 0G5, but will deal with that later. Of course the ROM had to have, I guess for lack of a better word, a custom bootloader, or index, to tell the phone it's okay to use this software right? So now have lollipop, but have lost TWRP on boot. I'm not sure as to why this has happened, but it's a real pain I want to install and use ROMs on this phone. If I need to downgrade to have TWRP, that's no big deal. So here I am a lollipop stock ROM, rooted wihout TWRP, ugh.
Is there anyone who can help me find a solution to this, it's driving me mad. I just want to have a recovery installed and the klte version won't install. It must be a lollipop thing, but I would love to have cm12.1 when it comes out. And why does this stupid script keep popping up while I'm trying to type this. Just thought I'd share my frustrations or see if there is a way to get TWRP on lollipop?
Thanks in advance.
Hello,
Welcome to XDA.
To better assist you, your thread will be moved to your device Q&A forum linked below.
http://forum.xda-developers.com/verizon-galaxy-s5/help
The experts there may be able to help. Good luck.
U cannot load into twrp or safestrap above the n12 kernal.
If you want to access your recovery, you could try loading the n12 kernal via odin. Then use your recovery. Then reflash the right kernal for your rom via Odin to return to loading status.
That's what I hear is possible- you sound like you can rebuild if u get in trouble.
As for CM - we don't have an unlocked bootloader so that's unfortunately killing it at this time. We are stuck on stock rooted TW roms, or slight variations of TW roms.

Hey guys,
So I've had this DM-Verity issue for ages after I did an OTA update and I'm just fed up of it, is there a way to just flash a custom stock firmware on this or something that will fix it without going back to Samsung since they are being weird about it because it's an India version of the phone and they want me to take it back to india to repair, I just don't have the time and energy to do that plus it's a little illogical and crazy.
Any ideas appreciated.
All I wanna do is have it back to the normal Samsung firmware (updateable) but without this stupid DM Verity issue.
P.s I've never done a custom rom or anything before although I've used Odin to try fix this with official stock firmware with no luck.
Thanks you
Hi guys, (sorry for the poor usage and terminology as I'm still getting acquainted with the rooting and custom rom culture)
BACKGROUND; I downgraded to Android 4.4.2 KitKat Baseband NB1, and from there rooted using towel root. This is an AT&T
SGH I337.
As stated above I'm running a rooted at&t s4 and I am trying to flash a custom rom on it. However after reading many tutorials and struggling, I've came to the conclusion that my MDL is preventing this from happening. I cannot seem to flash a rom no matter what application I use (I've tried Flashfire and TWRP with no luck) and on my most recent attempt to flash with TWRP the phone booted back to the same 4.4.2 kitkat interface and when I tried to access bootloader with home+volume up combo, a warning popped up and said secure fail kernel in the top right and in the center of the screen said "System software not authorized by AT&T found on phone." This made me come up with the conclusion that the MDL is preventing me from flashing custom roms. I've looked around and tried to find something to block the MDL, and the most common thing that pops up in the s4 forums is called Loki Doki, but I have yet to find a link that is not dead. So here I am with an s4 running KitKat which really sucks as I'm sure you guys can imagine.
That being stated, I would like some help on this and eventually be able to run a custom ROM. Any help is appreciated, Thanks !
