Upgrading Radio Bootloader Help~ - Nexus 4 Q&A, Help & Troubleshooting

Hi
I'm currently on 4.2.2 and decided to upgrade to a 4.4 rom namely SlimKat.
Just wondering whether I need to flash new version of radio and bootloader before the ROM?
I believe that I need to do a full wipe of my phone.
Does full wipe means the following?
Wipe Data/factory reset
Wipe Cache
Wipe Dalvik-Cache
Wipe Battery Stats
Do i need to format system and boot?
Thanks in advance

Yes, do a Data + System + Dalvik + Cache wipe and then flash the Slimkat.
No need to wipe anything else or flash new version of radio and bootloader.

[Q] wiping out before flashing

Hello,
I just want to ask whether I am wiping my phone correctly.
I'm using Amon Recovery image and then to Wipe and press option 1, 2, 3 which is Wipe data/factory reste, Wipe cache, Wipe Dalvik Cache ...
Is that enough to wipe or should I do something else before flashing?
I ask because on my 2.1 32b magic I have happened to have applications from previous flash and i did wipe correctly at least I think.
Thanks

[Q] HELP PLEASE.. With changing roms..

Was just wanting to know that waht are the steps to be taken when changing a rom,
1. Wipe data/factory reset
2. Wipe cache
and do we even have to wipe DALVIKI cache???
do we have to do all the above three processes???
please help...
It's better to wipe the dalvik cache too.
Yes, and as a Precaution, I wipe /system too under "Advanced". BTW, if you are using a new version of Clockworkmod (3.0.2.4 or newer), it includes a "Wipe All (Dangerous)", which does all required for a fresh install, with just one click.

Questions: Flashing custom ROMS

Do you need to Wipe Data/Factory reset from CWM when flashing from a custom rom to another?
or can I just wipe cache partition, Dalvik cache & battery stats.
If I do Wipe Data/Factory reset from CWM, does it erase your internal SD card?

[Q] Updating Custom Rom

Sorry if this is a noob question, but currently my phone is running on the alliance rom for t-mobile (here: http://forum.xda-developers.com/showthread.php?t=2748569). When updating to the current version, is it necessary or advisable to do the whole factory reset, wipe dalvik and cache shenanigans, or can I just install the rom by flashing it over the current install?

Blisspop: updating without wiping data

Hi,
I've recently done a succesful flash of Blisspop after a full wipe.
Now I want to update, but I don't want to do a full wipe. Simply installing the zip on-top gives a permanent booting screen. Can you update without starting from scratch?
Did you wipe cache & dalvik after flashing updated zip?
I did not. Is that the only required extra step? And will I lose data if I do so?

No, you only lose data when you wipe the data partition
In recovery, you'll see different named partitions, cache, dalvik cache, system, data, etc etc
If you wipe System, you wipe the ROM
If you wipe Data, you wipe your user data
Caches are just temp partitions, safe to wipe any time, only side effect is a longer first boot as Android needs to re-cache everything
But yes, you do need to wipe the caches when updating to a newer version of the same ROM/Droid version, and no you won't lose your data
Here's how I do it:
Wipe System
Wipe Caches
Flash new ROM
Flash new Gapps
Flash SuperSU if needed
Wipe Caches again
Reboot
Result = New ROM with no loss of data
That's a clean flash, a dirty flash is how you did it without wiping System
If you are moving to a newer version of android, or a different ROM, wiping data becomes more necessary, especially if the move is to an older version of droid
Thanks. I'll try it out.
