[Q] flashing a new ROM - EVO 4G Q&A, Help & Troubleshooting

noob question...
I successfully rooted and flashed my first ROM (warm two point two) on my EVO. I want to try other ROM"s as well so should i do the Nandroid backup again for the new ROM i want to install? wouldn't that erase my original stock ROM and prevent me from going back to stock?
thanks in advance for the help.

If u do another Nandroid u will have 2 Nandroids to choose from when u restore
You don't lose any Nandroids unless u delete it

okay thanks. for some reason i thought they would get wiped.

Don't waste your time with ROMS. There is nothing better than fully rooted stock IMO. I just tried my first 2 roms and really wanted to like them but at the end of the day I went back to stock.

well you maybe right. but i'll check them out and see. this warm two point looks real good though.

I've tried reading but I need help. I flashed a ROM already. I want to flash another!

Okay I have flashed Calkulin's Rom

The one without the OTA update that killed Root (I haven't updated to that yet )
I rooted using Toast's method - I did part 1 of his root. For part 2, I did this one

I'm trying to flash a new ROM now. Maybe damage protection or even FROYO (Yeah froyo sounds better)
I also want to do the NOVATEK FPS bandaide as well.
I just don't know where to start. I read somewhere someone said you just re-flash a rom again with the recovery...but I don't want to screw up.
Can someone post a very brief what I should do or lead me please?
FYI, the Rom you flashed from the first link provided is stock rooted with the latest update.
Anywho, you heard right, you flash new roms the same way you flashed that Rom. Download the Rom to your sdcard, boot into recovery, wipe data cache and dalvik, flash from sdcard, choose the Rom you put on there and confirm. That's all there is to it!
The important thing to remember is to always wipe before you flash, this will ensure no errors occur.
Hey thanks for backing up data I heard nandroid and titanium which one is better

Two different things. You should have at least one nandroid that you know works, this is used encased you beef anything up from flashing or something and you want to return your phone to the exact state it was at when you did the backup. That's the purpose of nandroid, to backup a complete image of the state your phone is in, Rom and all (excluding radio and wimax)
Titanium is a utility you use to backup all of the apps you have installed, along with their data and market links. This is usefull when flashing a new Rom so you can easily restore all of your apps without having to download and install them again and again.
Check this, it answers quite a bit of your questions and then some.

When is best time to perform Backup Flash?

I have rooted, installed Amon Ra flash recovery, and currently using CM6.
I forgot to do the backup flash when I had my stock rom, so I went ahead and backed up the CM6. Is that okay?

uhhh well, if you didn't need you're old stock rom or ever wanted to flash back to it you needed to back that up aswell, im guessing you atleast backedup your data and apps using mybackuppro or titanum?
From my research so far...and I have yet to actually commit to first root...you could just load the rooted 1.47...set it up...and back up that.
But...if I have the terminology right (please experts chime in as it will help me too)...titanium or whatever only backs up stuff...not the rom.
Nandroid back up is everything....
Which did you do? If you back up all the apps and whatever settings with titanium or my backup...then you should be ok regardless of rom.
If you are talking nandroid backup....then CM6 is now your fall back for everything.
So...my plan is to do my first nandroid with rooted 1.47. (Well it is at this moment in time.)
ps...is it nand or nandroid...oh well.
I could always download the stock rom, flash it as my backup, and go from there... correct?

yes, that's an possible option.

But...remember difference between stock Rom and rooted stock Rom...at least that is what I am reading. If you want to keep root...use a rooted version of that stock Rom.
(I have seen one thread saying could be issues.)
ps...again more experienced please chime in.
if you want to be safe dl rooted stock rom, flash radio then wimax then rom, once thats done do a nandroid backup of that then a nandriod restore of cm6 presto all warm and fuzzy with backups.

This is correct you can always just re flash a rooted stock rom to get back to the ... rooted stock rom. since CM6 nightly is still a bit touch and go and probably not ready to be most peoples daily driver i would suggest doing this sooner rather then later so you have a fall back.

This isnt exactly true. It does not back up radios, hboot, recovery. This usually isnt a big deal unless you are switching between roms using 1.47 and the older radios.
What i personally do is keep a fall back nandroid (or nand both same) of the stock rom as well as one for each rom i tend to play with (right now i have a cm6, dc3.5, and dc 3.2.3) this way i can easily restore to the roms i am playing with (cm6 dc 3.5) or back to my daily driver (dc 3,2,3) with out having to much of an issue.

Just rooted, nandroid question

So i've just rooted my mytouch slide (had a g1 running CM 6) however, i'm alittle hesitant to flash a custom rom mainly because I'm unsure of the degree of backup nandroid provides....maybe someone can clear it up - please answer only if you know for certain.
Running stock and rooted, if I do a nandroid backup - and decide to flash CM...then decide I want to go back to stock - Can I easily use the nandroid restore function? Will i get back everything? Will I get back stock apps such as swype? Honestly I would think the answers to my questions are "yes" but I really want to be certain.
Thanks in advance!

Wrong forum.
But yes, a nandroid backup will restore everything. Settings, applications, themes, emails, etc.
oops! thanks for the clarification! next time i'll try to post in the right area
Yup, think of nandroid taking a snapshot of what your phone currently has.
exxxcellent, sounds good enough for me! I always figured it would restore me back.....obviously thats the point, but i never had an issue with my G1 so i figured it didn't hurt to double check. Thanks for the help.

I was in the same situation, never had to use Nandroid until this phone.

What is the correct method of switching back and forth between roms?

I would like to better understand how to correctly switch back and forth between roms.
Whenever I have put a rom on my phone, I have done a full wipe and reinstalled from scratch (and then made a nandroid backup.)
I don't understand what I need to do once I get my MikFroyo set up the way I want, what steps need to be taken to back it up how I have it and then how to correctly load up a new rom?
And another question, when I go from one ROM to another, if I use a backup of some sort to load up, what areas need to be wiped prior to restoring the backup's?
So what do I need to do in order to switch up between Sense based and AOSP roms depending on the mood and what I am feeling on any given day that will allow the least amount of time but the most accurate and correct method of doing this?
Thank you for the help,

The best bet to keep your settings would be to do a nandroid backup after you set it up the way you want and then rename the backup to say something like Latest Mikfroyo.
Then wipe, flash, and reinstall apps the way you want it either manually or using Titanium Backup or Appbrain. Then repeat for every ROM.
I have a ton of backups made already for almost all the ROMs out there and I switch back and forth for testing purposes.
Try not to keep the nandroid on your SD Card since it takes up a ton of space.
But there are differences between certain ROMs. Some might use A2SD or only work with a certain kernel. So you would have to keep those as well. Rename them to match the correct ROM as well. So MikFroyoKernel.zip for example.
Nandroids won't back up the correct kernel. So you would want to wipe > flash kernel (if needed) > reboot > boot into recovery > wipe > restore nandroid.
That will do it for the most part. But mind you, sometimes the nandroid will fail. Not sure exactly what causes this but you can always restore another backup. Sometimes flashing the original ROM then restoring works as well.

If you do full wipe won't have any problem going between Sense and AOSP. Just don't import your settings cause could mess things up.
Also, I always wipe/format the sd-ext as well. Depending on how you are set-up could have apps from the old rom show up in new after boot.

nope, it dont matter if ur going between aosp or sense, nand will restore everything... but u might wanna read up some more on the latest amon-ra recoveries dat have been released, because whenever i do a nand restore, i get stuck in a boot loop, n its quite annoying...

Only if there is an existing backup to go to. OP really didn't specify whether switching between Sense & AOSP backups or new installs in that last paragraph.

What if I didn't nandroid?

So I rooted awhile back using the long step by step method and unrevoked forever since I have a newer phone that requires that root method. In the process I didn't do a nandroid backup, but did backup my 4g keys,etc. Is the purpose of a nandroid backup just to have something to revert to in case a new rom fails? Would I be fine just doing a nandroid backup of my rooted and flashed phone, or is there a reason I should flash back to a stock rom and do a nandroid that way? Thanks for the help, just want to make sure I don't leave myself stranded one day.

Its just a backup to restore in case of a bad flash. If your current ROM is working, just make one now and tuck it away somewhere safe. You're good to go, no worries.

Ditto. As Long as you have a backup of a working ROM, you should be good to go. Luckily I haven't ever run into a situation where I needed it. Usually if I find something slightly wrong, I just switch ROMs. I need less of an excuse than that, actually.
A backup is very, very, very important!!!
Just recently, for example, my text messages were acting funky and so I decided a reboot might alleviate the issue, perhaps. Upon rebooting, I got stuck in a boot loop. Thankfully, had myself a backup to just restore real quick and get on with my life.
It needn't be of a stock image, just one that has no issues so that you can always go back should something occur. Usually, that's why people perform one immediately, since there are clearly no flash-related issues when you're on stock!
But, it would be fine to go ahead and perform one now. In fact, perform one now. That's an order!
