[Q] Installing Custom Rom over 4.3

So I was getting sick of running CM 10.2 on my Galaxy SIII so I decided to go back to Verizon stock 4.1.2 rom and then before reading up on the 4.3 OTA update, I stupidly just went through the update. I didn't know how much of a hassle this was going to be, but basically I was wondering if anyone has any information on how to get off of this standard rom and back into the world of custom roms. Because I really really dislike touchwiz and really just about everything to do with this OTA update that I've had to deal with for the past pretty much month now. Any information will be helpful on steps I can take to get off of this ROM or if any work is being done to make this phone rock as much as it did when I first bought it.

Saferoot and Safestrap only available option right now.

I may add that saferoot is to root your phone and safestrap is used to install TouchWiz custom rom only.

how to get a clean 4.4
I've done the same thing as well with a similar issue, is the consensus that there is no way to move from a stock 4.3 updated phone to a clean non-touchwiz 4.4 such as CM11 or similar? My phone is quite slow and laggy after this update especially the keyboard, so I'm looking to pare things down to speed it up.

[Q] Verizon GS3 4.3 - Questions on unlocking bootloader and installing ROM

Ok, so, like the title says, I have a Verizon Galaxy S3 with 4.3 (Firmware VRUCML1). I already rooted it. And after trying to install a custom recovery without unlocking the bootloader, I had to use Odin to return to stock. And then, I bricked it after trying something else.
So my question is, what are the proper steps I should take (after rooting, since I already did that), to installing a ROM?

Get to stock than download safestrap and use safestrap to make a rom slot. Than you can install a TouchWiz 4.3 custom rom. Unfortunately if you are on stock 4.3 than that is your only option as you can not unlock the bootloader.

Like ImUnderTheBed said, safestrap and 4.3 TW ROMs are your only option. Everything you need is pretty much covered in the OPs of these two threads:

Ahhh ok, so basically, find the safestrap apk for my phone, then I can just install a tw rom. is there a certain version of safestrap that works? Or just safestrap in general?
Also, so, since you said only TW roms, I'm assuming that roms like AISP and MIUI are out of the question. Or just Kit Kat roms in general?

There is a safestrap thread in the development section, use that one. Can't flash any AOSP ROMs, only 4.3 TW ROMs

Help on a MF1 baseband upgrading it to "?"

Im a S4 and now a S5 user and this Verizion I535 S3 is looking scary. Two years ago I got the phone, unlocked the bootloader, installed a custom recovery, and installed CleanROM Seven. It has 4.1.2 Android Version with MF1 Baseband. With so many threads on updating to 4.3 and 4.4 is very bad with this version of phone, what options do I have? It's GPS is all mest up and hope to improve some battery by putting a new updated ROM on it. Can somebody point me in the right direction and show me some good options with links?

As far as roms you have many choices. Have you tried tightening the screws on the back of the phone? I've read people have had luck with that. I'd stay with the unlocked bootloader

Currently I flashed the latest TWRP and found a old Synergy Rom that's dated April 2013 that runs 4.1.2 and is MF1 based, other then that ROM can't find anything else that I believe would flash correctly. After installing the ROM, GPS was not fixed, and came across the "tightening of screws trick" As everybody has posted, it worked! Nevertheless, on day one got a random reboot and a forceclose on the camera. Still looking for ROM choices that I could use.

Glad to hear the screw option worked. You can always go with a rom that's not 4.1.2 based. There are plenty of custom roms out there for the S3

I know it can be done on my GS3 SCH-I535

Hello everyone. This is my first post and I am quite new to the world of smartphone modding. Literally, I have only been learning about this for a few hours. In those few hours I have been able to root my SCH-I535 4.4.2, soft brick it and reflash the stock ROM using odin. So I learn fairly quick and can follow basic instructions. Anyways, thats my intro.
So here is my goal:
1) Update my GS3 SCH-I535 FROM 4.4.2 TO Marshmallow 6.0.x.
So here is what I think I know:
1) The SCH-I535 has a locked bootloader which cannot be unlocked and therefore recovery programs such as TWRP or Clockwork will not work which means I cannot install any ROMS via that method. Correct? This is how I bricked my phone using TWRP.
2) There is a recovery program called Safestrap which CAN be used to install ROMS but these ROMS have to be specifically written to work with Safestrap? Correct?
So here are my questions:
1) Can anybody point me to a tutorial or help me achieve my goal?
2) Where can I find these Safestrap specific ROMS? I have read there is a version of Cyanogen13 for Safestarp. Is this correct?
Thanks in advance.

Correct, your device will never be able to use custom recovery or custom CM/AOSP based ROMs, you're stuck with Safestrap Recovery, modified stock ROMs and Xposed framework if you want to use it in addition to a ROM for more customization.
The safestrap compatible ROMs are stock based and there are no 6.0+ or 5.0+ versions for Verizon S3 that I know of unless I'm missing something.
If you want Lollipop or Marshmallow you'll have to port a stock firmware from one of the other S3 variants or other Samsung devices with similar hardware that has 5.0+ or 6.0+ stock firmware available for it.
Porting is done to convert the firmware from the device it is made for to the device you want to use it on, you'll need a copy of Verizon stock firmware and a copy of the firmware you want to port, then you extract them both and switch the vital stuff from the Verizon firmware over to the firmware you want to port. It's probably too complicated for someone with just a few hours of experience though.

Not to mention there's also no 6.0 stock roms available on any S3 variant.
Additionally OP, it's more than being compatible with safestrap, the roms have to be compatible with the stock kernel because you are unable to change that.
Only way you can get a 6.0 rom is to compile your own AOSP rom, delete the AOSP kernel, and configure that rom to run off of the Samsung kernel. It would be a difficult task, but it has been done before. Nobody has done it yet for this device. And I wouldn't have the slightest idea where to find the information to do that.

Well thanks for the replies. I guess those videos I watched are fake or maybe I just didnt understand them properly. I guess my wife will have to be happy with kitkat..
Now I just need to figure out how to root my SG5 sm-900v. Can someone point me in the right direction? I tried using a guide I found here on XDA but just ended up softbricking my phone. I reflashed the stock though.
Thanks

It depends on which stock firmware version the S5 has, typically it involves flashing a kernel then using Towelroot to root then install SuperSU then disable Knox then flash a second kernel as mentioned a few posts down in the thread linked below, it has two links you'll need to follow, a few posts below the post with the links mentions the order that you do it in.
androidforums.com/threads/verizon-rooting-samsung-galaxy-s5-sm-g900v.908621
But I think in your case your firmware might be too new and is probably locked down. It's another device that can only use Safestrap and stock based ROMs. That's pretty much what you'll get with any Verizon Samsung device these days, they're all locked from 4.3 and up, its possible to root but no true custom recovery or custom ROMs.

There is a thread linked below that is a discussion of a service provided by a company called MobileTechVideos .com to unlock bootloader for you or unbrick a locked device that has been bricked by flashing TWRP. I don't know if they still offer the service though. They may even do it for the S5, who knows.

Thanks for that post. I checked the links and it requires me to downgrage to 4.4 which I don't want to do. I am on 5.0 and I just want to root it. At this point I dont want to install custom roms or modified stock roms. I'll keep checking for a tutorial for an S5 5.0 root. I tried one here on XDA but I softbricked so I had to reflash the stock.

There isn't a working root for Verizon S5 on 5.0+ that I know of, Samsungs usually require flashing TWRP or CF Auto root but those can't be flashed on locked bootloader devices, only results in softbrick/bootloop or bricked.

rom for galaxy s5 sm-g900a at&t

Good day
Previously I had a Galaxy S3 and I was using CyanogenMod – Loved it!
I just always preferred a phone that was clean and lean without all the bloatware.
Now I’m with the S5 and there is possibly an option available for a custom ROM for my phone?
Currently –
SAMSUNG GALAXY S5 SM-G900A AT&T
Lollipop 5.0 G900AUCU3BOC4
So far as I can tell this phone could not be rooted.
Until a few days ago I got a notice in an email that it was now available.
I was on their mailing list if something should become available.
oneclickroot
I know you can’t go backward LP 5.0 – KK 4.4.
One can only go forward, LP 5.0 - LP 5.1 or LP 5.0 – Marshmallow.
However most of what I have seen out there for my phone has been LP 5.0.
At present I’m looking at these unless someone can suggest something else.
TMS5 3.0 ROM LP5.0
Twi5ted lollipop V7 LP 5.0
Alliance V8 ROM LP5.0
My question is, can I go from LP 5.0 (Stock) to LP 5.0 (Custom)?

If you've got the locked bootloader then you're out of luck rooting and flashing TWRP/Cyanogenmod.

Actually the phone is rooted now. Right after I posted this I used Kingroot king481.apk and Titanium Backup is installed and Root Check confirmed its now rooted. Although I have not tried the Bootloader...... With my luck that is another issue..... I wonder if I should try the first step with the Bootloader and see if SAFESTRAP or TWRP can install?

Safestrap is no longer supported and with locked bootloader you're not gonna get TWRP to work.

HI all, I'm new here and this Is my first post (question), Is There any solution to this issue (sm-g900a not taking custom recovery)?, I need (really want) to install android pie and magisk on my att g9005a,and most of the posts (including this one) are several years old.
Really appreciate an an answer, even if its still, "sorry, still out of luck",
Also, is this a good place for this, or should i start a new thread?
Thanks.

Your device is an AT&T variant, your device has a locked bootloader, you can't install custom recovery with a locked bootloader. The bootloader on your device can not be unlocked, you will never be able to install custom recovery on your device. If you want custom recovery you will have to get another device because you will never be able to use custom recovery on the device that you already have.
