Ok, I have not flashed my G2 (Sprint) in a long time since ZVA. I have ZVC rooted but no recovery. I want to install recovery so that I can flash ZVD Affliction rom.
What are the gotchas?
Do I have to downgrade the boot loader ?
thanks
Easiest way is via Autorec:
http://forum.xda-developers.com/showthread.php?t=2715496
downgrades bootloader, installs recovery, patches the kernel. Really painless and easy. of course, read up in that thread if you have questions.
Some sprint phones get a white line issue after flashing, but I did not.

I know there are a few threads regarding this issue but I can't seem to find a definitive answer.
I am currently running stock 4.3 jellybean (rooted). My phone hasn't received the 4.4 KitKat update yet, so I wanted to install CM11 in order to get KitKat on my s3. However, I heard CM11 can be buggy on the s3, so in case things go south, I want to be able to revert back to the stock 4.3 rom. Some people have said that you can easily flash the stock ROM via ODIN. However, others said that downgrading from 4.4.2 to 4.3 will hard brick the device since installing CM11 updates the boot loader. So downgrading to 4.3 stock with a 4.4.2 boot loader will cause a hard brick according to other threads I've seen. My question is, how can I downgrade from CM11 to stock 4.3 safely without bricking? Thanks in advance.
If you are sure you are using a Canadian version of the i747m, you can flash back to stock in Odin using a stock 4.3 ROM for the phone's original carrier (Bell, Rogers, Telus).

Yes I got the phone from Rogers, it's most definitely i747M. But do I have to worry about any issues with the bootloader? I'm assuming installing CM11 will install the 4.4.2 bootloader, so if I choose to downgrade to the stock 4.3 rom, will it cause any issues seeing as I'm running a 4.3 rom with a 4.4.2 bootloader? I just want to make sure because I heard it can cause some serious problems if the bootloader is newer than the rom.

I have never come across a custom ROM that touches the bootloader. A compatible bootloader has to be loaded on the phone before you attempt to install the custom ROM. Supported bootloaders can be found in the ROM's updater script.
I assume your phone has no warranty since you rooted it on stock 4.3. Did you root it by installing a pre-rooted ROM?
You could copy a ROM to your external SD card, install Philz Touch via Odin, reboot directly to recovery, create a nandroid backup, wipe cache, Dalvik, data, and install your KK ROM.

Okay, I was just making sure because I know OTA updates can change the bootloader, so I just wanted to make sure the custom roms don't do that. As for the custom recovery, are you recommending Philz Touch over CWM and TWRP? Do you know which custom recovery is installed from the CM installer?

Oh and one more question, my phone was originally carrier locked to Rogers and unrooted on 4.3 jelly bean. I brought it in to a cell store for them to carrier unlock it for me, but they used a rooting method to unlock it (because SuperSU was installed on it when I brought it back). They didn't unlock it with a code, so I'm guessing they used something like Samsung Tool or z3x shell. If I install CM11, will I lose the unlock, considering it's more of a "soft unlock", or is the unlock permanent regardless of how many roms I flash? Thanks for your help!

Philz is based on the latest release of CWM and I prefer CWM over TWRP because I had problems flashing ROMs. Once I switched to Philz/CWM, no more problems.

The unlock should be permanent. I unlocked it using the free method when on 4.1.1 and no ROM has ever caused it to re-lock. Reflashing a completely stock ROM, including the bootloader, did not relock the phone.
Please remember that flashing and changing ROMs will always carry a risk of soft bricking or hard bricking your phone. Make sure you read all of the guides and be prepared for disaster.

Hey guys ive gitten up to the point now where im rooted running cwms latest touch recovery. I need to upgrade my bootloader in order to flash any 4.3+ roms. Can someone help me with this process.

I posted a link to help you in your other post
The link you posted leads to a rom thread. Is there something specific in there I should be looking for. The one you lead me to talks of downgrading not upgrading
I rooted my dad's phone a while back ago so he can use tethering in case of emergencies etc. He recently got a smart watch and I wanted to updated it so that he can use it. But it has not been touched since that day. I essentially want rooted stock rom, I'm unaware of where to find that the closest I can find is StockMod kitkat. Which seems to not work on ATT phones? I just want to make sure that I don't brick his only phone on christmas. So is there something I should be aware of?
His model is SGH-i747
Baseband
i747UCDLK3
Build number
jro03
So how do I go about upgrading it? Can I just flash TWRP and flash any rom using TWRP?
I found this, so I should install new TWRP, then flash a specified kernel then flash rom? would this be safe route?
Some of the latest ROMs require a 4.4.2 bootloader and modem.
The simplest and safest way to get the latest bootloader may be to flash back to unrooted stock 4.1.1 and run OTA updates until the phone is running the latest KK ROM. You can then flash TWRP or CWM and a custom ROM.

Would this require flashing with ODIN? I just want it so that it works with root is not required anymore.
Yes, you would flash the 4.1.1 stock ATT ROM via Odin. I prefer Odin 3.07.
You cannot install OTA updates with root.
You can try flashing just the bootloader and modem but I prefer the long slow route of OTA updates.
I rather do it this way, manually so my dad can enjoy it today. I was wondering how can I update it's TWRP? it's at 2.3 but the TWRP manager keeps crashing when I update it.
I highly recommend the latest d2lte version of Philz Touch for recovery.

Ok I ****ed up, flash that kernel and did whatever and bam ****ed up. Not working... ****, I still ahve download mode and Recovery but it will not boot into the OS. I get a flash of samsung and then nothing else happends...****
I decided to flash stock DLK3 in odin. Then let the updates take it course (my dad doesn't need root) Where Can I find the file?
The stock ATT firmware is on sammobile.com.
If you want root, OTA to the latest 4.4.2, install Philz, flash supersu via recovery.

Here is the easiest thing. Update TWRP, backup. Download zv8 radio, ROM for ls980, gapps(some prefer pa gapps minimal).
Wipe, flash ROM, flash radio, flash gapps.
Reboot and wait.
Reason for new TWRP. Backs up radio. You can go back to your previous without concern for radio.
Is this confirmed working? I've been having the same issue, but I flash the radio, then rom and gapps, and TWRP loses my backups, have to flash the .tot again.
Ok, I tried this out and it works perfectly Follow the exact method in the second post. If you installed TWRP with AutoRec you will be on JB bootloader, make sure you use the ZV8 radio, which is the JB radio. For GSM unlock just dial *#*#4636#*#* and select GSM Only. Good day all.

Just download the latest TWRP zip and flash it while in your current version of TWRP, then reboot.

Hi I need help. I recently got this phone.
Rooted it with stump root, and flashed TWRP 2.8.4 using flashify.
I tried to flash a custom rom, but the wiping data part had an error. Stupidly enough, I proceeded to flash the rom zip and it got stuck flashing so I had to power it off. Now my phone is stuck on the boot logo. The only thing I can do with it is turn it off, or enter download mode. But I can't enter recovery mode. I read somewhere that it is possible to go back to stock recovery using the flashtool. Problem is I don't know which firmware I have. The only information I had about the firmware was that it was ls980vze because that's what I saw when I was flashing something. How do I deal with this? :crying:
p/s if there's a way that I can access twrp, maybe that' would work because I made a nandroid backup before. Don't know if that's useful though.

Okay, quick and easy.
There is a zve tot, though before we do much. Custom ROM as in which one?
Anything CM based is radio zv8, if it is a cloudyfa ROM; you can be zva to zve radio.
So depending on which can save trouble.
Root, depends on which version you are. Zv8 - go with ioroot25. Zve - use stump root.
Next thing, forget flashify. Sometimes it works sometimes it doesn't. Tried and true method, Auto-rec. Only after root.
Upgrade TWRP through TWRP by gator's zip of bumped and such. Or use TWRP app.
Again if your zv8, flash your CM based ROM of choice.
Zva-zve, flash your stock based like cloudyfa's Roms and such.

I tried to flash Validus ROM so i'm guessing that's zv8? I am rooted btw. Wait so you can upgrade twrp by flashing another twrp file? When I used flashify, after flashing the 2.8.4 bumped twrp it rebooted to my current twrp 2.7.0 and flashed it so I thought it was just the same. I'm pretty sure I am zve. Can I flash a zv8 rom if I have a zve rom? How do I get out from the bootloop?

Basically you're stuck using the ZVE tot to bring it back to factory. Be sure to boot it at least once as the phone will have to re-activate itself.
Try the zv8 modem

And if not, then try you and always check the op carefully before flashing.
