[Q] About to unlock, unencrypt, root, and rom! please check if correct

I bought a nexus 6 on google play and I am on verizon. It is currently running 5.0 LNX07M.
Could some nice fellow please tell if if this is correct?
1. download wugfresh
2. download drivers
3. tick usb debug, oem unlock
4. unlock bootloader
5. flash no force encrypt
6. root
7. Trwp
8. Get Chroma/ or any other 5.1.1 rom and flash with gapps?
I'm espeically concerned if it is ok to unlock and root a 5.0 nexus 6 and then use twrp to flash a 5.1.1 rom. Should I first update the phone to 5.1 or something?
1. download and install adb/fastboot
2. boot into the bootloader and plug in via USB to your computer. depending on what your computer is running, it could download and install the driver by itself or you would have to.
3. fastboot OEM unlock unlocks the bootloader.
4. reboot and back into your bootloader.
5. flash twrp recovery
6. flash your custom kernel and SuperSU for root via twrp recovery.
7. only if you want to decrypt, format your storage. if not, just reboot.

if updating the official way, go to 5.1 then 5.1.1. but if updating via custom ROM, it doesnt matter, you can flash 5.1.1 over 5.0
IMHO,
1) download Android SDK or minimal fastboot and ADB or 15 second ADB and fastboot installer
2) connect to PC and reboot to bootloader
3) from command prompt:
fastboot devices
(Serial number shows up)
4) From command:
fastboot oem unlock
fastboot reboot
5) Download the latest TWRP recovery for shamu
6) Boot back to bootloader and from command (having placed the TWRP image somewhere where fastboot can find it i.e. in platform tools in SDK) also rename it to twrp.img
Issue the command:
fastboot flash recovery twrp.img
(Be careful to not have it list the file ext. twice. Windows names the file ext. by default. Example: twrp.img.img
After recovery flashes, from bootloader, use the volume keys to select recovery mode and press power. Your device will boot to TWRP.
Make a backup!
Next, download SuperSU zip and flash with TWRP.
Congratulations, you are now stock rooted and you can choose any ROM you like and flash with TWRP. Follow the instructions carefully from the ROM OP and profit.
It may look complicated but trust me, it's not. The longest process will be after you unlock the bootloader. Your device will wipe completely so backup anything you'd rather not lose forever.
Remember, a 32gb Nexus will take 10 to 15 minutes to wipe and reboot. A 64gb will take 20 minutes or more.
The benefit of doing it this way is you know exactly what is happening to your device, unlike a toolkit. Also, you just learned something! Plus, if you get stuck somewhere and end up soft bricked, you'll understand what and how when someone here tells you how to fix it.
Thank you guys for your responses ! I think my laziness is going to win me out this round so im going to use the toolkit. But next time, I will do the correct way!

[NEED HELP] I need help. and will deletehis asap

i have a symphony roar a50 (Bangladesh). it was running everything stock and updated with twrp 2.8.7.0 without root. bootloader was unlocked.
i was trying to root the device with the AIO from this thread:
http://forum.xda-developers.com/cro.../android-one-toolkit-unlocks-relocks-t3294448
the phone suddenly rebooted in the middle of the process and was stuck in a bootloop. i tried to factory reset it but it still didn't work. was still on boot loop.
then i tried to flash the appropriate stock firmware but that didn't help it wont boot. stuck on the boot logo for 1.5 hrs. then tried CM13 nightlies and the cyanpop roms. still nothing.
i am currently in a state of shock as this is a fairly a new phone and i am to travel to Chittagong in ~11 hours.
please help
don't you take a backup ?
and don't you wipe every thing before flashing the cm13 ?

1) FLASH TWRP RECOVERY
2) Reboot into Recovery and FLASH Thunderzap 5.1 Kernel through Recovery
3) Then FLASH SUPERSU ZIP from Recovery
4) Reboot And Done ! Ur Device is Rooted ! ?

Internet full of guides how to do this and you need to read first 2-3 lines
THE STEPS TO FLASH
Step 1 – On your computer, do these tasks :
1. Extract the ADB Fastboot Files .zip file, and then
2. Extract Mi_Stock_Recovery.tgz file. You’ll have a file namely recovery.img.

Just use MI Flash to restore your phone to stock. Then you can start over and flash what you want.

Bricked in FASTBOOT mode after flashing TWRP. Need Help.

Hi,
after flashing twrp recovery, I made a wipe of everything even deleting os.
Now the phone starts only in fastboot mode, I can't go into recovery mode, I tried to flash flash roms fastboot with mi flash pro, but without success. I tried it also using command -fastboot oem edl, so in edl mode, it seems to start but does't complete flashing.
I'm reading a lot things about same problem, but I'm not able to fix...
What have I to do?
Thanks.
Use XiaomiFlash to flash a Stock Fastboot Rom from miui.com
There is a instructions how to flash it.
First you can try flash twrp:
fastboot flash recovery twrp.img
reboot (press volume up before hit enter and hold to boot twrp)
Don't use xiaomiflash/miflash, it's also bricked my phone yesterday.
Try this. If you want flash stock Download minimal_adb_fastboot_1.4.3_portable (search for link) and fastboot rom from http://en.miui.com/a-234.html
Unpack rom twice (tgz > tar > folder) and unpack fastboot files into folder with unpacked fastboot rom!
Open cmd in this folder and type:
1. flash_all (if you want wipe everything)
2. flash_all_except_storage (if you don't want wipe storage)
3. I do not recommend command flash_all_lock unless you know what you doing.
Wait for flash end and phone reboot.

Question RECOVERY BOOTLOOP

Hello guys!
I am having a problem updating my current TWRP (version 3.52 came from one youtuber) to TWRP 3.6/OrangeFox.
I carefully follow steps. Even extracting my own rom boot.img just to flash it in accordance to said step. I successfully flash the said recovery but when i reboot to system or power off. It just keeps booting to recovery. Hoping for some enlightenment. Thank you!

2) what do you need twrp for?

I already root my device . Just confused why the posted updated TWRP and Orangefox (both by Woomy) doesn't let me boot to system.
