[Q] CM10.1 and Locked Bootloader

I stupidly accepted the latest 78 update and am now stuck with a locked bootloader. I'm working on rooting my phone now (thanks to the guys @ http://forum.xda-developers.com/showthread.php?t=2379833) but am left with a question... can I load a custom ROM, say CM10.1, with just root?
Is there any utility out there to unlock the bootloader, or a way for me to downgrade from the current baseband I'm at now?
Thanks.

No. You need to be unlocked so you can install a custom recovery. That being said, you may be able to unlock the bootloader if you can root it.

I did get the phone eventually rooted. I found an old thread that showed how you can use SafeStrap (basically a wrapper around the original stock ROM) to install other custom ROMs with... is this a safe bet? I still have a locked bootloader as I took the new update... tried motopocalypse and it came up with the error code -11.

The thing about Safestrap is it don't flash the kernel when you try to flash a 4.2.2 rom so when you try to flash it keeps your stock kernel with a custom rom and it don't work out well
Flashing stock based ROMs with ss is fine though it's how we used to do it haha

Flash T-Mo Firmware on AT&T i337

Hello, I've installed tons of custom roms on quite a few different devices before, but this is the first one I've owned with a bootloader that can't be unlocked and I'm still kind of confused as to how all of these workarounds function and what ROMs they're compatible with. I've unlocked the phone and am using it on T-Mobile. It's currently on the MLD KitKat leaked version.
This is possibly wrong, but my understanding is that you are currently unable to install custom ROMs like CM and Omni on this device. So would it be possible to at least flash the stock T-Mobile ROM instead of AT&T? Right now, I have no access to hotspot, which is included in my plan, and I'd also like to use WiFi calling if possible. Has this been done before and is it possible on my firmware?
Thanks in advance for any help; it's greatly appreciated.

You can not flash their stock firmware. You can, however, use Safestrap to flash a ROM from their section, which as long as it is based from the stock firmware will have those features.

I have flashed HYPERDRIVE ROM with T-Mobile compatibility pack and works fine ! Even WiFi calling works!

Thanks, guys. I just got back from a trip and I'll be attempting this now.
Are there any AOSP-type ROMs that will work with this?

Also, if you havent done so, you might want to enable AWS for further compatibility. You will need to use the stock AT&T TW ROM in order to do so.

Do I need any sort of Loki kernel or can I just pick one and go with it? I'm looking at this rom right now. http://forum.xda-developers.com/showthread.php?t=2682842

Since you're using Safestrap, you can't flash a kernel anyways due to the locked bootloader. You should be able to go ahead and flash that.

Out of scene for a bit... need rom switching advice.

So I've normally been good at figuring stuff out on my own when flashing custom roms, rooting, etc but it's been awhile since I've messed with it and it seems things keep getting tougher (or maybe it's just me). Anyway here is the story... I am currently running JasmineROM (Android 5.0 Lollipop) on my Verizon Note 3 (SM-N900V), but I was considering upgrading to a version 6 Marshmellow rom like Temasek. One problem is that for some reason, I never installed a custom recovery so I am not sure how to proceed. I guess my questions are:
1. Do I need to downgrade to Kit-Kat somehow to install TWRP, and if so, what is a good guide?
2. What is the best, fastest, bloatware-free Marshmellow custom rom out there for SM-N900V right now?
3. I looked at the installation instructions for TWRP and it says to only use a specific version depending on whether your bootloader is the upgraded kit-kat version or not. How do I know this? Would it be updated since I'm using a 5.0 rom?
Sorry for the noobish questions and thanks in advance for any help!

Easy answers:
1 you can not back rev to KitKat
2 you can not install any custom recovery until you unlock the bootloader
3 you can not install any version of Marshmallow until you have installed a custom recovery because there is no official Marshmallow for the Verizon Note 3
Look in this forum for how to unlock the bootloader.

a. Unlock bootloader: http://forum.xda-developers.com/ver...l/official-note-3-verizon-bootloader-t3359370
b. Install TWRP ( I used 3.0.2-0 ) the easy way: https://play.google.com/store/apps/details?id=com.jmz.soft.twrpmanager
c. Install CM13 ( This is the only MM ROM I could get to work on the Verizon network) - http://forum.xda-developers.com/ver...opment/rom-temaseks-unofficial-build-t3364382

Thanks for the help! I managed to figure it out myself after realizing I needed to unlock the bootloader. Thanks for taking the time to post!

S5 SafeStrap ROM Help...Can I use CM13?

Hi. Using a CID11 device w/ KINGROOT/SAFESTRAP
I know the bootloader is locked and all, but will I still be able to use CyanogenMod 13 ?
http://download.cyanogenmod.org/?device=kltevzw
I know this is a noob question as the S5 is pretty locked down now 'geocold' is helping the enemy, but is it still at all possible to use CM13 with this safe strap option on a CID11 device.
also is there any other ROMs I could use that are similar with any kind of custom kernel that helps preserve battery life like in the past or is that a no now since the bootloader is locked.
lastly will I loose root if I can do any of the above.
....
very new to the S5 please bare with me lol

You shouldn't lose any data but a backup is always wise
According to the thread you have to be on rooted PB1 firmware and use safestrap
The guide is specific so follow his guide exactly
I would do a back up in Samsung Smart Switch or Samsung kies 3 before you use or use safestrap backup whatever you prefer

Oh ok, yeah since I'm on OK3 will I need to do the whole KingRoot method again? or if I flash to PB1 from ODIN will I still keep root/safestrap/bb not sure how this all works just started using the S5 today.
Also once that is all done, and I'm on a rooted PB1 ... I'll be able to flash threw safestrap to a MM 6.0.1 ROM ? but when I do this wont I loose root? and I thought root not able to be obtained on MM 6.0.1 with CID11 devices? this is where it gets to be confusing for me, sorry for all the questions

You will lose root if you go up to cm13 using this method
If you need root then the linked method above may not be for you

Yes I can not use android with out root lol, but thanks for showing me all this anyways its progress I guess, not sure if this handset was worth the money now knowing all this, but I'll stick with it.
I see no point in even bothering to run CM13 or any custom rom really with out the use of root. ehhhh anyway. Backing up my apk/data using a snazzy lil app called MyBackup Pro. for the migration.
Thanks for the help. Looks like I'll be staying on the 5.0 OK3 rom then since at least I have it rooted, and some kind of recovery even tho the whole safestrap touchwiz thing is not pleasing its better than nothing.

Recoveries? Android 5.0.1 SGH-I337

How exactly do I go at getting a recovery now? I've tried installing twrp ,cwm, philz, and safestrap. The I337 I've heard has a locked bootloader though I find this hard to believe for all the custom ROMs. I heard others often experience "System software not authorized by ATT has been found on your phone". Help would not be taken for granted.

If the phone is running a 4.3 or newer bootloader, the bootloader is locked and can only use safestrap to flash custom ROMs.
There are many custom ROMs (there are different versions of the s4 and some of these custom ROMs may be unified builds for the 9505, 9515, i337m, etc.) but only those custom ROMs that can be flashed with safestrap can be flashed to an AT&T s4 with a locked bootloader.

If you're on Android 4.3 or higher then you can only use safe strap and boot touch wiz roms as your bootloader is locked and patched. If you're on Android 4.2.2 or below, you can install TWRP and boot other custom roms like AOSP and Cyanogen mod as the bootloader is locked, but not patched and can take advantage of the loki doki exploit to bypass the lock.

I have 2 phones. One 4.2.2 another 5.0.1. Is there a way I can update with twrp or another custom bootloader and then update to 5.0.1 (not through OTA). Which one should I use? Thank you.

There is no such thing as a custom bootloader for the att s4.

I'm still somewhat interested, even with safestrap. The bootloader cannot be unlocked. OTA update wouldn't be possible as it checks the recovery. I'm interested in ROMs and nandroids.

Is your 5.0.1 one on the OC2 bootloader? It then can only boot touch wiz roms. Golden eye rom and thor rom are good and both can be booted in safe strap which is the only recovery it can use. Your 4.2.2 phone is on the MDL bootloader right? If so use towel root to root it if not already root then install loki doki then install TWRP. After that pick a kernel and boot whatever rom you want...touch wiz, CM, AOSP, etc.

The bootloader lock can only be bypassed with the loki doki tool on the MDL and MDB firmwares. If you're on any other firmware then you're stuck with using safe srap as the bypass exploit was patched in the MK3 bootloader OTA update I believe.
