why wont ir recover?

hey guys i just rooted and flashed my first rom and mod theme and now that im trying to recover my info in cwm it runs thru a bunch of files and then says something about file does not exist or something i cant remember what and i dont want to do it again cuz everytime i do my phone locks on the samsung start up screen. was i supposed to partition the sd card or something? if so can someone give me a step by step please? PPCgeeks is down and i had a thread started over there that was helping but cant get to it.
if its not a partition problem then do u have ne ideas what it might be?

Please, help a n00b. I think I broke my Nexus S 4G

Let me first start off by saying that I am on a Mac.
I used these directions to get my phone unlocked and get ClockworkMod Recovery or whatever running on my Nexus S 4G.
I then loaded Cynogen onto my SD card, booted into Clockwork, wiped my phone, then tried to install Cynogen. It failed- it couldn't install boot.img or something.
Now, when I try to boot up my phone, it just shows the Google logo with the unlocked icon below it. It never successfully boots. I can still get into Clockwork Recovery, but below every menu section over the logo, it always shows some error like
Code:
E: failed to something something /cache
Can you guys please, PLEASE instruct me on how to get my phone working normally? I don't need it unlocked, just running the stock OS.
Anyone who can successfully help me do this on a Mac will receive a nice PayPal donation if they wish.
Thank you so much in advance.
And yeah, I know I shouldn't have been attempting this because I am such a n00b.

What version of CWM did you flash?
Pm me and we will use a chat service (aim, yahoo messenger) and I will walk u through it.
My suggestion of what I would do is this. Find a windows computer somehow. Go to the development section and look for the sticky about rooting the ns4g. Look for the link to flash the d720 back to stock. Download all those files to a flash drive. Take the drive to the windows computer and set things up then flash the phone back to out of the box stock.
Then you can go back to the Mac and do the root and 3024 cwm recovery and rename the sh file that puts stock recovery back in at boot time. After all this you can do what you want but I would suggest staying with the stock experience. This might be extreme to fix this but in my opinion, I wouldn't waste time trying to fix it, especially since you are new to this. It's like computers, yeah you could try to fix it but you could be opening a can of worms. It might take less wasted time putting it back to complete stock instead of f-ing around trying to figure out what happened and how to fix it. You could take hours trying to fix an install of windows that keeps falling on it's face, or you could format and install windows fresh and new in maybe thirty minutes. Which is easier?
CM7 will not work at the moment because it still uses 2.3.3, go find instructions for a 2.3.4 Nandroid. if you want though,i heard that supeaosp works on a ns4g.

Dude, you can't flash regular Nexus S ROMs on the Nexus S 4G.
Reflash the latest clockwork recovery.
Use fastboot flash recovery recovery.img
then...
Go to recovery, mount the USB storage, and put this zip on the usb storage:ROM
Go to recovery and flash that zip
here's the recovery that works. cwm and stock. How many times is this going to happen with new people and this phone in this forum section before a new subsection is made? We are going to be putting out a lot of these unnecessary fires with people making first time mistakes until something is done so as to not confuse them. Some don't realize that there are different versions of the same phone that aren't necessarily compatible with each other.
The way things are set up now, it isn't making this problem go away. I think that a different method should be tried if the current one isn't working too well. I'm flogging a dead horse now......
I'm looking to root my new NS4G as well -- and do it right the first time. On a Mac as well.
If the similarly-suited OP had issues I'm a bit more skeptical about my effort.
A separate forum might be necessary so people with the D720 hardware don't have near-brick experiences.

soooo....did the op ever get it running again? i wonder if anyone ever took up on his paypal offer

[Q] Roms wont load/pd15img.zip doesnt work

Hello everyone, First off I would like to thank all of those that have posted on this site and contribute to it.
Now to my problem. Let me share a little history of how everything started.
I first rooted my MT4G about a year ago, Tried to use IcedGlacier but it was not loading properly so I used cyanogenmod 6 I believe? I wanted to try IcedGlacier but It still was not loading properly. Then when I tried to restore it would not restore properly. At this point it appeared to be bricked but bootloader still worked but the PD15img file was not found. So after some researched I downloaded it and it restored my phone back to factory condition. Now I want to try other roms again because I'm getting bored of stock and attempting to load different kernels but this is where my issues are beginning.
As you can see in the attached photo that is what the bootloader looks like. I thought it was weird that next to hboot it says "HBOOT-0.85.2007 (PD1510000)".
(I tried to post the image but since I'm a noob I and unable. If you want to see the screen shot of my bootloader just message me.
I was thinking maybe this is a reason as to why now No other rom but the stock one will load. Also what is weird is that when it goes into bootloader it still says PD15img is not found but the phone will start up fine with the stock rom.
The phone remains rooted but No Rom or Kernel will Load and fully install.
When It loads roms it goes to install it shuts off and reboots into stock rom.
I tried to Use the PD15IMG.zip on the SD card to see maybe if it didn't load properly but it will begin to load with the blue bar in the corner but then after it goes all the way up nothing else happens.
I have been trying to look for answers but haven't found any real answers that help me fix my problem.
So if someone can help me I would greatly appreciate it.
The "no PD15IMG.zip" message is supposed to appear. When the bootloader loads, it checks the root of your SD for that file, and if it's not there, you'll get that message. Nothing wrong with that.
Since you're perm-rooted and running the engineering boatloader, you just need to make sure your recovery image is good. If you haven't already, download ROM Manager from the Market and use that to install a fresh copy of ClockworkMod recovery. From there you should be good to flash any ROM you want.
Thanks, I did what you said plus I realized when I was downloading the roms using a Mac and my Mac would unzip the file automatically and trying to compress it back to a zip doesn't work at all. But thanks alot for the help!
If the PD15IMG.zip doesnt work you probably dont have the part7-xxxxxxxxxx.zip file on your sdcard

[Q] Bootloops on own rom

Hello dear XDA Community
So, im facing some problem developing my own rom. After several failures, i was able to create a flashable zip of my rom. The problem is, that i get Bootloops after flashing it. So, i was not even able to take a logcat at the boot. The logcat file stays always empty. Now my question is, how am i able to find the error causing bootloops?
Thanks in Advance

Then after when I got a rom to sort of work with twrp recovery I switched thinking that was the problem. After resetting instead that one some how broke adaway and adfree there stuck in a loop and I can't call out that is what happens when I use twrp and I can't flash roms I even checked if the files were broken and they weren't. what recovery works or what is my phone doing with this rom or recovery ?

You didn't give us nearly enough details to know why you are having problems. Lots of people use TWRP without problems and TWRP can certainly install custom ROMs. To have any idea why you are having difficulties, you'd have to give us a detailed, step by step description of what you did with your phone and the error messages that you received.
.
Ok I'm not sure what details to give you I got my phone on I used a rooting process off the unlocker.com for my phone and it worked but my recover doesn't work no mater witch one I use i have s5 g900f for t mobile I'm not sure if I should just try re-rooting my phone maybe? Also the error I'm getting for installing anything is just abort and it can't install because it can't open? and I know the files are not broken tried downloading from computer and phone and saving to my card and the phone. What else do you need me to provide? I'm using the alliance rom that isn't working right because of what is going on with my phone. I can't go back cuz my backups don't work because my recovery isn't working no matter what I use because it will always not complete the restore in either.
I went to get a error message now and now I just get a blank screen in recovery so it's frozen and I can't bring up anything just the name of any rom I try to flash.

Well we can't see your phone. And obviously there is no way to know what is going on if we can see it and you don't describe what you see in detail. For instance you say that you had an error message. But you don't paste the verbatim message here. Don't you think that message might be useful, if not critical.
For effective troubleshooting, you should post a detailed description of what you did, step by step and what was on screen. But I already said that in my last post and you disregarded the suggestion. I'm sure that others will guess at solutions for you. But efficient troubleshooting isn't possible without information.
.
1 If I told you I couldn't post the error message which I did because the recovery screen is blank what do you want me to post? I mean there is nothing on the screen to post there is nothing there because it froze it does not say open or anything there is nothing there unless you want to see a blank background. 2 If you mean what I used to root it would be CF root. Other then that I tried philz and twrp both have the same blank screen when you try to open a zip to install. would you like a black screen for twrp or a or blank purple and pink screen for philz with no text ? I posted that I went for an error message but the screen is blank and I can't make anything happen now. I can't give something when nothing is currently there. I'm just going to flash stock and unroot then root and see if that fixes my problem.
