1. Check you have root access using root check from the market
2. Use ROM Manager app to install working CWM, flash ROM as OP instructed
3. Profit

Can not restore my phone

I want to preface this by saying I have spent 4 hours trying to recover my phone and I have tried all the things suggested in the treads, including what worked for me last time.
I installed a kernal for using the buttons backlighting for notifications which apparently works on the Fascinate. My phone never rebooted from that. I tried to install Clockwork and install an update.zip or an old restore file and it would not read off my SD properly/was not effective. I then tried using Odin to flash over the system, kernal, and recovery. Still no dice. I formatted my sd and tried to install clockwork again and everytime I try to access it through installing update.zip it says that signature verification failed and the installation is aborted and does not even reach clockwork.
I hope someone can help me. I have tried everything I can think of and have had zero luck.
PS: Currently my phone will show SAMSUNG but keep looping
Did you have voodoo on your phone before you flashed the kernel?

No, I was running a deoxed .4 rom
Are you installing clockwork through Odin? I have had problems with getting clockwork to work if I installed it any other way. It should work through Odin tho - also was the kernel you flashed with the backlight notification the voodoo one or non-voodoo?
Sent from my SCH-I500 using XDA App
Also did you try wiping data? Even if you can't get into clockwork you can do it from the Samsung recovery. I would try that and then do all the Odin recovery stuff again and see if that helps - but if you flashed the voodoo kernel you will have to go thru the post on completely removing voodoo.

I am installing through Odin. I don't know any other way to do it. I installed the non-voodoo one.
I installed this one since I heard it worked on our phone as well...

I have wiped every data thing you can think of several times. And do you think it would hurt for me to try to remove voodoo even if I don't think I flashed that kernal
I'm hoping someone more experienced than me will take this one - I'm not sure if that backlight notification you flashed is compatible with the fascinate. That could be your problem. Can anybody else jump in here?

You flashed a i9000 kernel onto your Fascinate. Ay caramba.
DON'T FLASH NON-FASCINATE ROMS ONTO YOUR FASCINATE
Anyway, I can't think of anything except trying to flash the Fascinate CWM kernel back onto your phone again with Odin.
edit -- FYI, the only BLN kernels any Fascinate owner should be flashing are the ones from jt1134, available only via ROM Manager

Figured as much... I read it worked and that is why I installed. Hopefully I can get a fix. Maybe I should do adb?

[Q] Flashing Custom Roms

Sorry for the noob question here, but I have rooted my Samsung Epic 4G and I am positive I am going to install the Froyo rom. However, there's a few things I am not sure on.
1. I downloaded rom manager, but after that, what do i do? Do I install that rom onto the phone and flash the clockwork recovery? Also, do I have to download the clockwork app off of the market first?
2. I know flashing roms requires a wipe, so is there any easy way to back up all my applications and data? I have heard of titanium backup, but I am not sure how to use it.
3. Does owning a mac affect any of these steps when it comes to downloading stuff?
If anyone can explain/post a video about these questions, I would very much appreciate it.
Thanks
Edit: during the clockwork recovery app, what are the controls?
I am still quite a noob myself but I can give you a little guidance. Find a root that includes the clockworkmod (I personally used noobnls all in on root method, it was simple and self explainitory, you can even unroot first and then reroot with it), once you have the root with CWM you can then use ROM manager to flash a ROM. Download the .zip of the rom, make sure it is an epic 4g compatible ROM. Put the .zip on your sd card, then use ROM manager. I don't use it though, I just shut the phone off and boot into recovery, the text will be green if CWM is running. Do a backup, wipe to factory, wipe cache, then install .zip from sd. Locate .zip file and flash it. Reboot and you're done. If you are going to flash a froyo rom make sure you read the first post of the thread, it will usually have instructions of what else you need to flash, how to download it and where to find it. Hope this helps, please remeber that I am still a noob and might not be perfectly accurate. Good luck

Also, I forgot, the appbrain app allows you to sync all your apps so after you wipe and flash a new ROM you can dl appbrain (free from market), and then reinstall all your apps, bad thing is I have not figured out how to do it all at once, and had to install each app individually.

Okay I think I get it, but what's the difference between flashing from the rom manager and boring up the clockworkmod?
Also, can I install the rom directly to my sd card?

Yes, you can dl the rom directly onto your sd card, I boot into cwm so that I can do everything manually and make sure it gets done (its just my preference you don't have to do this). Rom manager makes it easier, you can just select flash rom frm sd card, find the .zip file, it give you the option to backup and wipe and then boots into cwm to finish. Most roms, kernels and themes that I have looked at say wipe 3 times before flashing, that is the other reason I don't use rom manager, because it only gives you the option to wipe once.

Okay so the froyo rom doesn't require a wipe which is nice. Last question, do I need to have the usb plugged into my device as well as a computer? Thanks so much!
Sent from my SPH-D700 using XDA App
For a froyo rom I am not sure, everything that I read said youj need to use odin to flash the dk17 modem and pit, I haven't done that, but you will need a computer and usb to do that. I'm not sure about the rest, a look at the first post of the various froyo roms should tell you how to do that, I think the viper rom had some good details if I remember. Take a look there in the developers forum and see what you find, let me know how it all turns out

Bricked Nexus S

I am in a bit of a pickle. I rooted my brand new Nexus S, but in the excitement, I accidentally flashed a kernel for Cyanogenmod first instead og the ROM first, THEN the CM7. Now it won't go pass the unlocked bootscreen. I have searched for solutions, but can't find any. If only the Nexus S had a SD card, I would know what to do, but how do I get a stock kernel transferred to the phone when I can only get it into Clockwork mod? I tried factiory reset and all, but it is not the problem, it is the kernel. I can get into CWM but nothing happens when I try to mout USB storage to transfer files and/or new kernel..... Help, anyone? Please?

You can mount your sdcard from recovery, there is an option for mounts in the first menu. Then transfer whatever file you want to flash.

It doesn't work. Ther phone shows up for a split second in Windows file explorer and then closes again.
Please post the exact model of your phone and the exact file you flashed, and the exact CWM recovery file you flashed.
Also, if you can get to recovery you haven't bricked your phone
If you haven't done it already I'd also flash superuser. If you are after a stable ROM based on CM7, I'm using NSCollab 1.0.39 and works very well.

Which drivers do you have installed, just the ones from the Android SDK? what Windows do you have?

when you flashed cyanogenmod after flashing the kernel, cyanogenmod automagically overwrote the kernel that you flashed first, so thats not the issue. try wiping data, then reflash cyanogenmod and the gapps.
simms22, the issue occurred because after flashing the kernel, I could not flash anything because it just halted on the Google screen with the open padlock. I have now uninstalled and reinstalled the Samsung drivers, and it helped, I then could see the phone in Windows Explorer and was able to transfer a new kernel and a new ROM, which actually was the NSCollab which I like because of the speed. Thanks all for helping me out. Have a nice one.

ahh, i misread what you wrote. im glad that it got straightened out anyways
Good to hear
NSCollab 1.0.39 is pretty stable with the Matr1x 5.5 kernel it comes with and you'll notice a better battery life too.

[Q] Stuck on Motorola logo after cm7 flash

Now before anyone post the comment about there are other threads about this, i already looked and tried those methods for the past 4 hours. Nothing has worked. This is what happened....
I tried to install CM7 From CWM and when it was installing it didn't list anything that was inside the zip, it just said installing.........installation complete. i wiped the necessary wipes and reboot. Now i am stuck on the moto screen. my phone is Rooted, unlocked bootloader and i have cmw on my phone. i downloaded GingerMod and am going to try to put that to my SD card and see if it installs.
But i feel like i did that wrong to install the rom. If i am or if someone knows how i can fix my phone i would really appreciate this, i have a 1 year old son that is with his mother and i need to check on him and my job relies on my phone also. So over look my noobness and just someone help me, i would really appreciate it.
I'm using CM7 Mod ICS!
Everything runs good.
Try to install it.
Perform the appropriate wipes
Install the ROM zip from CMW
Install the zip of the GoogleApps
reboot
okay so i flashed the gingermod and i got past the dual core logo and got to the animated moto icon but it just looped it. so i am trying to flash it again and do the appropriate wipes. I will download that ics though and try it out if this doesn't work.

Which version? If it's not the newest one packaged with ROM Manager (or romracer's) then you're doing it wrong. 99.9% of the time this is what leads to stuck at boot logo.

ROM Manager is available in the market. You install CWM from within the app.
romracer's is here along with install instructions.
what are the "appropriate wipes" that you're doing?

[Q] Nexus 7 Failed ROM Flash Help!

I have CWM 6.0.1.0 on my nexus 7. I was rooted but running the stock ROM. I wanted to flash CM10. I booted into recovery, wiped cache, dalvik, and factory reset. I then flashed the .zip file. When I rebooted the device it never got out of the CM boot screen. That circle just kept spinning. I tried the toolkit but the drivers aren't really working on my computer (crappy old XP laptop). I have formatted the system and SD card out of desperation which was honestly a stupid thing to do. So, where I am at now. I have no way to boot into android. Everything is wiped and formatted. Toolkit, adb, nor fastboot will work. I thought fastboot would save me but I can't get it work. Not even on my wife's mac. So what are my options? Please let me know if there is something important I am leaving out.
It can take a while to get a new rom up and running. How much time did you give CM to install before you interrupted it?

I let it go for at least 30 minutes. I finally got adb to push a ROM to the device. Problem solved. Thanks though.

maybe it was a bad download?
It can stand a spell to get a new rom up and jetting. How some instant did you utilize CM to install before you broken it?

Thats possible. I tried re-flashing it numerous times but they all got stuck in boot. I am now up and running with SmoothROM. I might have to re-download CM10 sometime and try again.
Hey guys I now has a similar problem. I flashed a bad copy of my Rom and when it failed to boot I too wiped everything in desperation. I know I'm an idiot! Now I need to push both a Rom an kernal to my root directory but I'm not clear on how to install my kernal. Once I push my Rom I can use my recovery to install the Rom. But how do I install the kernel? I'm using cleanrom which comes zipped with the kernal. I can't fastboot flash it because I cannot turn on USB debugging. Gary

To use fastboot you don't need to have switched on USB debugging, it's sufficient to go to bootloader mode and connect your PC to it.
(If you have already installed the correct drivers on your PC.)
