How do I flash them? Do I have to flash via command prompt or can I flash via recovery?
Sent from my Nexus 5 using XDA Premium 4 mobile app

most are available through a flashable zip, those you can flash via your recovery. very few arent meant for all to use and are kept in a .img format, so those you flash via command line(but can flash via the flashify app as well).

Cant Flash Anything in Twrp

i cant flash anything in twrp everything i try to flash says failed. other than that twrp works fine. any ideas why?

Usually might have to reboot recovery in TWRP before flashing. Normally with Catalyst that is what it requires me to do and all works fine.

you will lose root, but not your data.
just reflash the custom recovery in fastboot, then supersu from the custom recovery.

Errr....... I have cwm so why do I need fastboot and is there anyway to get root back?

Because the OTA may include a recovery and replace cwm

Yep, anyway we look at this, fastboot is involved so embrace it and learn it because it's a must-know

Yep, sort of. You install cwm via fastboot but then you root via cwm by flashing a zip that has the root files in it.
The best bet is to get fastboot set up now before doing anything. I know it may seem daunting but once it'a set up, it's done and once you've used it, you'll realise you were worrying about nothing

OK thanks. Just one tiny question that I need explaining. How do I install CWM through fastboot. Do I download the zip of cwm and boot into fastboot once I'm on 4.4.3 using the button sequence power - then install?
Do I need to install cwm if I don't want root? And in cwm do I just flash on top without clearing data and cache

So a couple of things to clarify.
Ultimately, cwm is an .img file (a bit like a cd image). If you have a flashable zip of a recovery, it will contain a recovery.img.
Other flashable zips that contain .img files are kernels (boot.img) and radio (radio.img) but most other flashable zips such as ROMs and mods do not use image files.
Fastboot is a command line tool that is used to flash image files outside of flashable zips. So if you have a flashable zip of cement you want to use, you must extract the recovery.img
Fastboot works in 2 halves. Half of it is built into the bootloader of your nexus so to use fastboot you must boot into the bootloader and connect via USB.
The other half is the command line tool which is a fastboot.exe that you put on you computer and access via cmd (command prompt).
To use fastboot once it's configured, it's quite easy, you just type "fastboot flash" followed by the partition you want to flash too and the name of the file you want to flash. Usually you will only flash system.img, boot.img, radio.img or recovery.img and each flash to the same named partition.
Example
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot flash boot boot.img
One thing to remember though, is you either put these images in the same folder as fastboot.exe OR you type the full location when flashing for example
fastboot flash recovery c:\users\dec115e\desktop\recovery.img
Have a look in the 2 threads mentioned in my signature as they both should cover setting up fastboot.
Let us know if you have more questions

It depends how you do it but if you're using an OTA file or flashing the system.img and boot.img you won't lose data.
Only flashing a userdata.img which overwrites the data partition will loose your data

The easiest way to fastboot img. for Htc One S S-ON (noob friendly)

Give thanks to this guy!!! "mumilover"
http://forum.xda-developers.com/showthread.php?t=1193915
Download:
https://rapidshare.com/files/1908085...nderV.1.51.zip
Extract FastbootCommanderV1.51.zip on youre PC.
Boot your phone into bootloader.
Connect it to your PC via USB cable. It will show Fasboot USB.
Copy the image file "boot" from the rom you flashed and paste it in the folder "FastbootCommander"
On windows XP you have to extract the rom file to see boot.img. On windows 7 or 8 is more simple.
Double click on "WinRun.bat".
Reboot in recovery.
Wipe cache & dalvik cache.
Enjoy.

If you delete /system/etc/recovery-from-boot.bak (or similar) the recovery should stick also when flashing via fastboot and using TWRP 2.8.1.0

Fastboot.
Fastboot with a PC, flashify directly on device, zip file in recovery, terminal emulator+IMG file...pick one.
#stayparanoid
You can also use the TWRP app from the Play Store, which is probably the easiest way.
So how can i flash my updated version? I downloaded the version on my phone its in my downloads. I boot into recovery go to flash and it does not recognize the img.

You need a zip file to flash in recovery. Use the flahify app if you want to flash the.img file or flash it in fastboot
