Need some assistance understanding how rooting, bootloader unlocking, ROM flashing. I came from the Samsung Fascinate (i500) where there was no bootloader to my knowledge, flashing ROMs with ODIN or CWM was straight forward.
Out from box I used the following method outlined from PhoneRebel (http://phonerebel.com/how-to-root-a...-4-1-1-verizonattsprintt-mobilei9300-version/) to root and then unknowingly assumed that this process also unlocked the bootloader for flashing various ROMs (I was wrong). Next I installed goomanager and flashed TWRP Recovery. Following booting into recovery and performing a backup, then while in Recovery mode attempted to install CleanROM7.
As what appeared to be a normal install using Aroma, the phone then rebooted and the infamous triangle appeared. Guess I "tripped" because the bootloader was still locked, or better yet I did not know that flashing (VRBMB1_Bootchain.tar.md5) was a relocked bootloader! The phone was now soft-bricked without the ability to get to a lock screen or enter Recovery Mode. Download Mode was still possible.
Since I had the ability to ODIN, I then followed Hero's method (http://forum.xda-developers.com/showthread.php?t=1840030) for unbricking. I'm back to where I think I was following my first root. The phone is running Verizon TW stock 4.1.2 rooted, Android Recovery, and not unlocked.
I am looking to flash Scott's (scrosler's) CleanROM 7 (http://forum.xda-developers.com/showthread.php?t=1832070) or any other ROM.
Specifically what are the steps that I need to follow which allows me to install other ROMs? Do I ODIN an unlocked bootloader (VRALEC.bootchain.tar.md5), ODIN TWRP, reset counter using Triangle Away, reboot into Recovery and install new ROM? Do I need to lock the bootloader following the ROM installation? Do I need to Triangle Away to reset the counter each time I want to install a different ROM, or is it once I install a new/custom ROM, I do not need to worry about the bootloader?

this should work
http://forum.xda-developers.com/showthread.php?t=2332825
after you root, unlock the bootloader and havea c ustom recovery installed you can flash zip files like youre probably used to.
good luck
Triangle Away is only for those looking to return the phone to their carrier. Also you MUST have an unlocked bootloader to flash custom ROMs. So to recap once you unlock the bootloader you can start flashing to your heart's content.

Recently rooted my gs3 and was freezing some apps with Rom Toolbox.
Do not have a list of them all.
Phone now boots the "Samsung Custom" page and then hangs on "Samsung Galaxy III" page.
I can boot to dl and factory recovery page.
I have wiped cache/data factory reset.
I have tried to reflash the stock rom via Odin from the download mode and the sd card from recovery mode.
With Odin I get a "Failed" message and with the sd card it says "signature failed".
Not sure where to go next and any help is greatly appreciated!!

Did you flash a custom recovery after you rooted? Did you unlock the bootloader? Have you tried to flash a custom rom?
I would suggest Following http://forum.xda-developers.com/showthread.php?t=1762709 this guide. Section 5 to use odin to flash a stock image. You said you could get into odin/download mode then with the proper factory image and setup, you should be able flash back to K3 or G1 image.

I stupidly did not flash a recovery. I do not think the bootloader is unlocked, not sure how to do that?
Have tried to flash the stock rom and a custom rooted stock rom.
I have spent the better part of 2 days using the search feature and trying things. I'm a newb tho.
Thanks for any more ideas.
Use section 5 of the guide I linked for you to restore via Odin the stock factory rom.
Then search through the stickys for guides on root/unlock boot-loader/custom recoveries. read them twice and if you still aren't sure ask questions. Plenty of friendly folks to help you. I would hate to see you brick your phone trying to flash a custom rom with a locked boot-loader. Most roms require an unlocked boot-loader. You will need a custom recovery to flash roms and make nandroids/backups. the recovery's will be CWM or TWRP. Make sure you use Odin right or you could have a paperweight. Make sure you download the proper factory image to use in Odin.
When all is done properly there is little risk. Good Luck!
I used this guide when I made the mistake of installing a custom recovery without unlocking the bootloader XD. http://forum.xda-developers.com/showthread.php?t=1974114

Hey guys.
I just got a very nice condition used TF700T. I am trying to get recovery to install so I can flash a rom. I used the Transformer Toolkit to unlock it, which worked, it says device unlocked when booting.
But I absolutely cannot get it to Root, or flash recovery. If I try using debugfs root generic 2.3 it fails to write everything. If I try to flash any recovery with the toolkit it downloads and says flashing but just sits at about 25%, it boots my device into the screen that says usb fastboot mode with the three icons that say RCK Android and factory wipe. If I click the RCK it says rebooting and then goes to android mascot installing icon, but then the one with an X and error appears. What on earth am I doing wrong?
Is it the latest 4.2 update locking me out? Can I downgrade? I just can't get anything to root or flash recovery no matter what I do. I feel a little defeated being a long time member and 3 phone habitual rom flasher :crying:\
Any ideas what i'm missing?

What custom recovery are you installing? You may want to try with fastboot or adb method to flash your custom recovery which doesn't require rooted device, good luck....

Well I tried TWRP 2.7.1.1 I believe and also CWM , and Phil's custom touch CWM that all three are options to flash with the all in one ADB Toolkit app via USB from windows (http://forum.xda-developers.com/showthread.php?t=2094746)
How do I do the Fastboot method? I read about that, but have no idea how the process goes. I'm ok with skipping root and going straight to recovery and a rom because I can just flash superuser after if the rom isn't rooted already.

I wanted to try an app I used to get twrp onto my LG G2 for the first time called "flashify" that worked like a charm. I just installed the app, downloaded the twrp file and flashed it then it reboots to recovery, but it requires root as far as I know. Does unlocking the boot loader allow things like this?

Unlocked bootloader is allowed you to install the custom recovery so you can install the custom ROM, I believed..... You can check this guide out to see if you can setup your fastboot/adb. It is very easy to follow for the beginners, good luck....:fingers-crossed:

Once you unlocked the bootloader you can flash a custom recovery and after that - the sky's the limit.
Flashify works great, and it is a wonderful tool as long as you're able to boot into Android.
My problem with Flashify and Goomanager and TwrpManger is that it saves users from setting up a proper ADB/fastboot connection from PC to tablet.
As long as you can boot Android, these apps are great. But what if you can't? Once the tablet doesn't boot it's so much harder (and often too late) to get the correct drivers installed for ADB and fastboot.
So if you flash your recovery with any of those apps still make sure you have access with ADB and fastboot from your PC.
You will regret it if you don't - I (almost) guarantee it.
That's an excellent point. Thanks. I did actually get the Fastboot method to work. The problem was that I kept clicking into RCK recovery when I ws supposed to just leave it on that screen to push twrp instead. I got recover and just got done doing a backup. I'm about the flash my first rom (http://forum.xda-developers.com/showthread.php?t=2672751). Do we need to do factory reset / wipe data/system etc? The instructions on the ROM post say to just flash it from twrp so I'm guessing it has a built in wipe feature during install?

The instructions in the OP actually say that you have to do a full wipe (Factory Wipe) in TWRP coming from a different rom base. Which would be you unless you had a version of CROMBi-KK installed prior to this.
It's the default selection under the Wipe menu in TWRP. Just do that and then flash the rom and your ok.
Do not use the Factory Reset option from Settings or the Wipe Data option from the BL menu! Do this in TWRP only!
Cool thanks. I figured so because that's the norm with roms on all my phones. Thanks a lot for the help guys. So happy to be get KK running on my new toy!
Just wanted to update. KK 4.4.3 rom flashed and booted in. It's much nicer. The stock was a little laggy, and KK breathed a lot of new life into my ancient single core 1.0 ghz Galaxy S that I use as a music player so I figured it would help make the tab real nice and snappy too. Gotta go now, much fun to be had!!
So I did the lollipop upgrade got root and unlocked my bootloader but I think I used the wifi build to update with but it works fine. However my tablet says there is a new update out and I know it will kill root and recovery but will it matter since I unlocked the bootloader? Update has been sitting there for awhile because I keep putting it off.
If your bootloader is unlocked you can flash any recovery (Cwm, philz or TWRP) via fastboot and then use it to flash supersu zip file from it.
An unlocked bootloader lets you flash unsupported firmware; e.g., another bootloader, custom kernel, recovery or ROM. Don't worry about updating, but expect to have to reflash recovery and re-root the device after pulling down an OTA.
Hi and merry Christmas
I do rooting for years, but never separated process of unlocking bootloader and flashing custom recovery. All guides speak about that phone will be wiped.
My bootloader is unlocked, but I am back on stock recovery. Will my phone be wiped when I flash custom recovery?
TIA!

Flashing of custom recovery needs unlocked bootloader. Unlocking of bootloader wipes your data. As you said your bootloader is already unlocked. Then you can flash custom recovery without worry of data loss.
Just flashed recovery via adb fastbook and installed supersu. All good, all data there
Hello there,
Recently I wanted root on my J3, but then after unlocking bootloader and installing TWRP via Odin, I keep having these messages pop up telling me these apps stopped working.
Now I know if I just lock the bootloader, it will brick the device (from my research).
I now want to get rid of TWRP, and install stock recovery, then lock the bootloader.
Thanks,
Cody
you can flash stock rom. it will be fine probably
