I really want to install cyanogenmod on my galaxy s3, which already runs kitkat, how would I be able to do this. Everything I have read says that i will brick my phone!!!
On XDA, there is no exploit that exists that will allow anyone using a Verizon S3 to use AOSP. The only existing route is to use a service such as MobileTechVideos and pay $50 for them to downgrade your bootloader at which point you can unlock the bootloader and eventually run AOSP.
Alternatively, but a different phone.

Was trying to root my Galaxy Slll SCH-1535 with the Samsung GS3 toolkit but noticed my phone isn't even close, well maybe close, but not close enough to any one on the list. I have a 16 GB Developer Edition that came as a 4.1.2. It has open source licenses and claims to be a truely universal phone that i can use on any network. My build version is JZ054K 1535VRBMB1, which is not an option in the toolkit. So how do i root it and trade out the Verizon for Metro Pcs? Any help would be greatly appreciated, and if I'm in the wrong place I apologize. Thank you in advance!!!
I didn't think it was that unlocked... I thought it was only unlocked bootloader. Anyways, have you searched here? There's several guided floating around on how to flash to another carrier.

Didn't quite understand you there. i did go ahead and root it, flashed(?) CWM recovery, installed superuser from zip,and ready to remove bloatware and anything verizon to flash CM10. just not sure what to remove exactly. do you, or know where would i find out?
Hi,
I spent last night getting my t-mobile galaxy s4 to work on ATT. I did a lot of research on the subject and it wasn't that difficult at all. I bought the phone off of EBAY.
I was able to accomplish this from all of the tools here and a little research. http://forum.xda-developers.com/showthread.php?t=2335109
The first thing i did was root the phone and install CWM. I then used the sim unlock found in the link above. The next step i took (because i like custom roms on my phone) was to install TASK650's AOKP rom. I flashed the rom and followed his instructions.
After the restart, I went through the welcome screen and shut the phone down. I put my sim in and started the phone. I noticed i was getting the H, but no LTE. This led me to more research. The fix was easy once I found it. The APN needs to be pointed to the ATT phone option. It defaults to wap.cingular. After about 5 minutes and a reboot the LTE appeared and after the speed tests confirmed.
This is not a guide. I am just sharing my experience. If you do this please do your own research as you can do damage to your phone. There are risks involved, flash and modify your phone at your own risk.
Just wondering, why did you get a tmobile s4 to use with att? Normally the att version can be found for cheaper price
Sent from my GT-I9505
I am confused here, what is it you were trying to accomplish? running a att rom on your tmo device? Because you say you have a tmo phone.
Why go thru all that, when this rom is already setup to work on tmo with the tmo apn settings already setup for you.
[ROM] Task650 AOKP (Jellybean 4.2.2)(6.26.2013)
Do you new people just go and see a rom you like, in any forum, and do not look in your devices forum and flash it? if so, your are asking to brick your phones.

If you want an unlocked bootloader, can't you just install the custom recovery?

Does this method work on the verizon Galaxy S3? Has anyone tried it to confirm it works? I want to downgrade so I can root and install cyanogenmod which I can't seem to do with the 4.3 update.

Yeah I'm a new member and I just learned I can't post links, yet. but the method is from Androidpit and the method requires using Odin and a .tar file of an older version
At this point I'm pretty sure all methods have been tried to downgrade back to 4.1.2

If you took the OTA 4.3 update, the bootloader is locked and it has blocked ALL earlier factory versions and all non factory ROMS.

I looked up your specific tutorial, it definitely will not work.
That only works on the international model. As a general rule, never trust a guide unless it says it's specifically for the Verizon galaxy s3. It's locked down much tighter than any other s3 models, and many alterations that can be performed on the other variants will often brick this model.

You can still root, install a ROM with Safe Root or Safestrap or whatever, and have a better-running phone. You simply can't install a different kernel... it sounds like you can even still have a custom Recovery (modified TWRP is my understanding).
OK

I can't post links but if you search for thread number 2565758, that's everything you need for the Saferoot method that works for the Galaxy S3 (usually). I say usually because it doesn't work on my phone but I know plenty of others that have had no issues.

I've already used saferoot but I can't get into custom recovery with it, and I can't use custom ROMs because of the update, that's why I've been looking fr a way to downgrade to 4.1 or something.

Want some advice? Sell the S3 for a pre-4.3 S3 or sell the S3 for another device. Theres no guarantee that AOSP will ever work with Safestrap.

Well I have been considering dropping a bit of money getting a used international S3 because the Cyanogenmod installer would work with it, but I don't think my Verizon SIM card would work in it.

It wouldn't, you need a CDMA device, the international s3 doesn't have CDMA bands. Verizon leaves you pretty limited in device selection.

That's what I thought, so that pretty much just leaves me with Verizon versions of the phone... I'll make sure not to stick with verizon when my current contract expires.
I need some help here, I have an unlocked bootloader S3 with CleamRom 8. It's been sitting around unused for many months. I gave my S5 to my uncle in exchange for his upgrade and ordered a Note 4. In the meantime, now I am using this S3 again. I almost don't care about root anymore, can I just flash the 4.4.2 tar and have Kit Kat? If anyone ever uses this again after me, it would be someone in my family that busted their phone. I am guessing stock kit kat is far more stable than these AOSP roms. I have been out of the S3 game for atleast a year. Any feedback would be appreciated.

If you want to keep your bootloader unlocked, you need to flash a modified version of the stock firmware so your bootloader does not re-lock. I am using the official cyanogenmod rom and I have been for months. So far so good. No glitches or jumps or jitters.

There is absolutely no way to unlock bootloader on kit kat or newer, period. Attempting to use anything custom of any kind will only lead to a brick and then it requires JTAG to recover the device but even that isn't guaranteed.

Question: If I never intend to use the phone on a cell tower again - meaning I'm just using it at home on wifi - does that somehow allow me to do more than just root on 4.4? Even after debloating, this thing is getting really clunky and slow.
I wish there was a way to revert to a less-resource-demanding OS so that this phone could be faster for browsing, watching Netflix, controlling smart home stuff, etc.

If you have 4.4 then you're stuck with it. Your only other options are using Xposed or using Safestrap Recovery with modified stock ROMs but I think Safestrap is no longer available unless you find someone that has a copy somewhere, I think the modified stock ROMs are still available, not sure, I have the Straight Talk S3 and use the Verizon custom ROMs, never used Verizon S3 or Safestrap but I'm familiar enough with the Verizon S3 to know what you can and can't flash it with.

Um no. It was locked down by Verizon. You can thank them for it. The real reason is because they like to make customers miserable. But no the real reason is they want to have control of everything and don't like it when customers can take control of their own devices
