Root Question about ROM flashing

An UrgeTo Dance

The Hero of the Winds
Okay so When I ran unrevoked on my phone it messed up but it was able to get s-off and I was able to put RA recovery on it, but it did't root the stock ROM. I was told that all I needed to do was flash a rooted ROM. When I first rooted my phone I tried to flash superuser app from recovery but it wouldn't, it said it could not verify the signature. My question is is it safe to try and flash MikFroYo, I already did a Nandroid but I am wondering if it will do the same thing it did when I tried to flash the SU app.
 
The super user app doesn't get flashed, rather, it can be installed frrom the market, if it doesn't install from unrevoked. How exactly did you try to flash it? And you must have SU now if you were able to make a nandroid backup. So, since you have a current nandroid backup, you should have no worries in flashing a custom rom. If for some reason it doesn't work, you can restore to your bckup.
 
Thanks and I dont have SU in the stock ROM but I face custom recovery and s-off I just can't get the stock ROM rooted and I tried flashing SU from a zip file I was given

Are you sure you don't have SU? No SU icon in your app drawer? Did you try installing it from the market? I have a stock rom, rooted with unrevoked, and I had to dl the SU app from the market.
 
Yeah I'm sure I don't have it I downloaded it then went into TE and typed in su and the prompt did not change plus after I downloaded it, I downloaded wifi tether and it said I needed root access and so did ROM manager. When I rooted it gave an error code but it gave me s-off and a brocken recovery, so I flashed RA because I heard it was more reliable. I then tried to install SU through a zip file some one gave me from the unrevoked chat room. It didn't install because it said it could not verify signature, so then I came and asked here and akazabam told me I just needed to flash a rooted ROM but I don't want to start flashing it then it runs into an error and then something is wrong with my phone. I was able to make a nandroid so I have a backup but I still don't want something to go wrong .
 
Gotcha, and sorry to have interrupted akazabam's help. I read that he is out of town for a few days, so perhaps one of the other EVO root experts here can lend a hand....and I understand your concern.

Edit, but if akazabam told you to flash a rooted rom, then I have 100% confidance in his instructions.
 
So I read your previous thread on your issue, and from what i understand is going on is that sometimes unrevoked makes errors and that your error was that you did not get su flashed. from what akazabam was saying is that you can get su by flashing a custom rom. so to answer your question about flashing mikofroyo, is to go ahead and flash it. as long as you have a nand backup you should be good to go. also by flashing the rom, it should give you su. you should also download from the market a terminal emulator and check to see if your $ changes to #.
 
You might also want to toogle signature verification in Amon Ra. Pretty common problem when trying to flash unsigned zips.
 
Hey everyone I was talking to someone else who is/was having the same problem and we are pretty sure the fix is indeed just to flash a working recovery and then a rooted ROM. Does anyone know if my recovery may be broken since it wouldn't flash the other zip or was that just a problem with the zip?

You can flash whatever ROM you want, now. You have everything need (s-off and a custom recovery) to do so. If I told you to flash a stock rooted ROM, it was only so that you could start with a clean slate. Read as - aside from having wiped data, start where you would have if unrevoked had finished cleanly. Go ahead and flash whatever ROM you want.

The super user app doesn't get flashed, rather, it can be installed frrom the market, if it doesn't install from unrevoked. How exactly did you try to flash it? And you must have SU now if you were able to make a nandroid backup. So, since you have a current nandroid backup, you should have no worries in flashing a custom rom. If for some reason it doesn't work, you can restore to your bckup.

1) If I remember correctly, Superuser is provided in both an apk and flashable zip format.
2) You need a custom recovery to make a nandroid backup. You don't even need s-off to make on (you'll need it to make it useful), and you certainly don't need superuser (root access) in the ROM to make a nandroid backup.

So I read your previous thread on your issue, and from what i understand is going on is that sometimes unrevoked makes errors and that your error was that you did not get su flashed. from what akazabam was saying is that you can get su by flashing a custom rom. so to answer your question about flashing mikofroyo, is to go ahead and flash it. as long as you have a nand backup you should be good to go. also by flashing the rom, it should give you su. you should also download from the market a terminal emulator and check to see if your $ changes to #.

Yep. Unrevoked does three things:

1) Give you a custom recovery.
2) Give you S-OFF
3) Root your ROM.

When it fails at 1 and 3, you need to finish manually. Flashing a custom recovery is easy. Since unrevoked failed at rooting the ROM, just flash a root ROM of your choice. It doesn't have to be stock. It can be whatever you want.

You might also want to toogle signature verification in Amon Ra. Pretty common problem when trying to flash unsigned zips.

The thing was that the zip was signed but it was saying it could not verify the signature.

Does anyone know if my recovery may be broken since it wouldn't flash the other zip or was that just a problem with the zip?

It could be a problem with either recovery or the zip. Yes, you can toggle signature verification, but that's meant more for zips that weren't signed. Where did you get your recovery image from? Did I give it to you? I don't remember. Go ahead and download Mikfroyo, and try to flash it. See if it works or if it errors out as well. Flashing a different recovery (or reflashing what you've got) is easy enough. It's possible that something went wrong while flashing it. I'd blame the zip, first, though? Have you tried to flash anything else?
 
No I haven't tried to flash anything else yet, should I try something else before I try a ROM? Also if something does go wrong while flashing the ROM such as that error coming up will it mess up my current ROM because I will try flashing another recovery first if I need to.

My guess is that there's nothing wrong with your recovery image. I could be wrong, though. So...

1) You have a nandroid backup, so if the ROM flash doesn't work right, just nandroid restore. What all did you back up as a part of your android backup? If you're using 2.2.1, it should have given you an option. Make sure you have well over 30% battery before trying.

2) If you get the exact same error, it simply means that it failed to verify the package was signed correctly. This could be from a bad download. In any case, it's a pre-flash check to verify the integrity of a file. It means that it will not have messed up your current ROM if that's the error you get.

3) If you do run into a problem, the first thing you can try is a nandroid restore. If there is a problem with your recovery image, you'll have to reflash it or flash a different one. If you flash something other than a different version of RA, you won't be able to restore you nandroid backup. Keep that in mind. You got RA from a PC36IMG.zip, right? You can keep that file on the root of your card for now if you want. It will prompt you to flash it every time you go to hboot, but you should be able to just ignore it until you (potentially) need it.
 
I have RA 2.2.1 and I got it out of a PC36IMG.zip and yes I have a nandroid and I backed up everything except the last two on the list because I read that they were not needed and that they take up a lot of space.

Ok. I will say that I have noticed that RA can get confused if you restore a nandroid backup that doesn't *not* include .android_secure, and you've made changes to it (by adding different apps to sd via normal froyo apps2sd) with a different ROM. It happened to me once. I had to uninstall and reinstall most of the apps that were normally on the sdcard. It does take up an extra...maybe...80-100 MB, but that varies on how many apps you have. Anyway, if you didn't backup wimax, I suggest you have at least one backup including that before doing anything else. You're extremely unlikely to lose your wimax keys by doing something simples like flashing a ROM, but...just do it anyway :p. You don't want to lose those. Otherwise, you should be good to go.
