I'm I ready to flash rom?

Ok guys I'm new to the evo and just want to make sure I didn't skip any important steps. I have latest ota and rooted with unrevoked3 and got s-off with unrevoked forever. Flashed amonRa recovery and created nandroid.
I'm looking to try out the EViO Rom or Latest fresh rom. Can I just put the rom on sdcard and flash the rom from recovery? Or am I missing something?

Put the rom on the root of your card, wipe data, cache and dalvik cache twice, then flash the rom.

Don't forget to backup any apps with TB or MyBackupPro as well as the nand backup.
Good luck

wiping twice is a good idea after a duece, but it's a bit redundant when dealing with dalvik cache

Its always a bit redundant i think thats the point though. Honestly if the recoveries are wiping them correctly there should be no reason to do them twice, But it makes people feel good to do so more power to them.

[Q] Odin vs. One Click Recovery

To return to stock I was wondering if it was better to use odin or the One Click Recovery.
Do they both do the same thing?
Is one better than the other?
Thanks

Odin is only true way to go back to stock

I know odin completely wipes everything... if i just wanted to flash a new rom and kernel would that still be the way to go?

You need Recovery to change your Roms. Odin won't do that. If you looking to flash Roms, One Click by noobnl. If you wanna go back to Factory. Odin.

so then in all the threads when they say wipe everything they mean the clockwork recovery stuff. not a system wipe

Simple explination: When they say wipe, they mean inside of clockwork recovery you choose the option to wipe the cache, it would be like formatting a hard drive before you install a new windows os, u want to make sure all the old files and disk errors are gone. Same thing here, the cache is where the data/settings are stored.

awesome guys.. thanks for all your help

Not to be mean but no cache does not wipe your data. It's the equivalent to clearing cache on your browser. When a rom thread calls for a wipe they mean wipe data/factory reset, wipe cache, and go to advanced wipe dalvik cache.

I don't know about the whole format thing... guess you look at it that way. It only clears a part, and there's a few of those. But when you wipe your clearing all your data and setting. Each rom is built different. So in some cases you'll need to wipe to make sure nothing from the previous messes you up. The OP (thread starter) of the rom will say when to wipe. Should always wipe between roms. Cool thing is, you can advance restore your stuff back. ; ) or Titanium Backup. But something will alway catch you off guard or you'll forget. So have multi ways of backup. In clockwork you will see back up (Nand Backup as they call it), this backs everything up, if you mess up you can always go back like it was with restore. Have fun and don't let it piss you off.

With respect a454nova it should be clearer than that. If a rom says to wipe, the clockwork recovery probably should not be used to restore data because the ROM poster is probably putting something in data along with changing the system files. Titanium can be used judiciously to restore data files but only with full knowledge of what the OP has put in the data directory. Best practice is to use listables and download everything new then restore only items that could not be downloaded from the market

[Q] Installing acustom kernel

I interested in flashing a custom kernel but not clear on the steps. Do I need to wipe data/factory reset or just wipe cache before installing? A noob's guide for this is needed and should be added to the sticky thread in the Dev section.thanks for any help.

I just did my first kernel change a couple weeks ago, so I am new at the process myself - all I did ( as advised by members of the xda community) was to
1) boot into cwm and use nandroid to take a full system backup.
2) use cwm to install the custom kernel, just tossed the zip file onto the micro SD, selected install from SD in cwm, took about 10 seconds to install.
3) reboot
4) install set CPU and dance around like a idiot after realizing how sweet my Iconia runs
5) ???
6) Profit
In my experience, make sure to take that full backup and move it off tablet - just in case.
Hope that helps.

you might want to add step 2.5: clear dalvik-cache and cache.

I did not bother with this step - but now I wish I had if it is recommended
What's the logic behind this step? Just random curiosity.

so, do I wipe the dalvik cache and cache before or after flashing kernel? Step 2.5 sounds like after flashing just wanna be sure I do it right. Thanks for help.
Is there an option in CWM to make a backup of the stock kernel before flashing a new one?

Did you unlocked the bootloader? If no, you should start unlocking it but you will loose all data.

So what i need to do is unlock the bootloader than install custom recovery and boot into it and than flash the kernel zip did i get it right?

yeah, but i do it everytime to avoid any possible issues

That is absolutely correct. But, as suggested before you may want to wipe the cache and dalvik cache partitions before flashing, and before you do anything in the recovery, please make a nandroid backup to restore in case you face any issues, it is very important.

you never ever need to wipe dalvik nor cache when flashing kernels. they have nothing to do with kernels. its the same as going to wipe your behind so you can fill your car up with gas.

Alright, Thanks for the clarification. I am used to the old fashioned method that always told individuals to wipe the cache and dalvik.

its from the past, when android was still young and we didnt know better. everyone was just told to do it always, regardless. and no one questioned it. but as we learned more and more, some upgraded their thinking, while others kept up with what was told to them in the past. when flashing roms as well, there is no need to wipe dalvik nor caches, as the act of flashing the rom automatically wipes both dalvik and cache

Thank you very much for updating me! I greatly appreciate it. We learn something new everyday

you do it in recovery. it makes a complete backup of everything. so if you mess something up, you can restore it(also in recovery) and be back to the same place when you made the backup.

[Q] Wiping the whole phone

Boot into recovery and do a full wipe and you are good to go

Does that remove all the internal files?

Yes, it does. But there it depends on the recovery you are using. In twrp there is an option to wipe everything except the internal, but this is not recommand since you want to have a clean flash. Just make a nandroid backup.
