I have a Samsung Fascinate and had Cyanogenmod 7.1.0 installed just fine. Last night I tried to install Cyanogenmod 7.2.0 and now my phone is stuck in a boot loop. The splash screens for Samsung and Cyanogenmod show up, then it goes to a CWM screen that prints a bunch of stuff but it disappears before I have a second to read it and it continually goes through this.
What I have tried:
Holding the different physical buttons. Most of these did nothing, however with the volume down button by itself a screen comes up saying downloading do not shut off target.... It does nothing and I have to remove the battery to get out of that.
Fix through Odin. This doesn't work because my phone just constantly tries to boot. I cannot get it to register on a PC because of this... I do however have a card reader if that helps; however this doesn't work with Odin.
Delete the original Cyanogenmod zip file for 7.2.0 and download a new copy, then transfer to my SD card. I though maybe if the original download was corrupt it would help to install a new copy, but this didn't help at all.
After searching the internet for hours now and trying everything I have seen I have decided to post this and see if anyone can help. I just need to get out of the bootloop I seem to be in :/
Well, your phone can't bootloop with the battery out, so I suggest you Odin back to stock using the instructions in Droidstyle's guide. From there, you can do any number of things.
Good luck.

i've read almost every single post related on this subject, tried almost everything but no go.
recently, i installed SS-6 to my girlfriend's Vibrant but she didn't like it, so i attempted to revert to my nandroid from the original stock rom.. nandroid gave an MD5 error and did not installed.
at that point, i had already wiped data/cache, prior to nandroid.
i rebooted the phone, and now im stuck on the Vibrant splash.
i have tried to go to recovery mode via hard buttons but no go. i actually tested with another Vibrant and on that one, im able to get into recovery so it is not that i'm missing pressing a button or what not. been trying anxiously to see if im able to go either to download mode or get into cwm and flash cyanogenmod!
tried to use ODIN/ADB in order to boot into cwm to flash another rom, but it doesn't see the phone. ive already installed samsung drivers.
if i connect the charger, the battery indicator doesnt come up. it stays on that lined-circle screen forever, even after taking the USB cable out.
please help!
EDIT: added [Q] and added some more grammar errors.
any help is highly appreciated.
I had this same problem... The only thing that would fix it was this thing I had to buy called a Jig. It was less than $8 (with free shipping) on eBay.
http://www.ebay.com/itm/Fix-Download-Mode-USB-Jig-Samsung-Captivate-Galaxy-S-/140520601309
It delivered in 2 days and my phone is working perfectly now
just ordered one!
thanks!
one more thing, are you able to just install a different ROM through ODIN or ADB without having to do the full wipe? im wanting to save the contents of the internal SD.
thanks again
I've tried to look for this problem and haven't found anything similar. If it's already been addressed please direct me to the previous thread, if this is in the wrong place please move it.
I rooted my Galaxy S II a while ago and it's been working great. I wanted to try Cyanogen mod 7 and so I followed the instructions on their website. Trying to use ROM manager gave me a weird error message telling me that there was an invalid signature or something, despite toggling everything and wiping the cache to turn it off. So I followed the "method via recovery" instructions. I did everything exactly as it is there, including the Google apps stuff, and it all seemed to work perfectly. Then I rebooted it hoping for it to boot into CM7, and instead, when it turns on it goes to the screen saying Samsung Galaxy S II with the yellow triangle underneath, and stays there. Every time it turn it on it goes to that screen and doesn't change. It's now been like that for half an hour. I can start it up into download mode, and I've tried flashing zImage to it again, but no change.
I have a NANDroid backup (it's backed up with CWM anyway), and I've copied the backup to my computer, but I have no idea how to apply it when the bloody thing won't turn on.
I'm using Linux with Heimdall (the cross-platform Odin clone).
Please help me. Unfortunately I have no internet in my flat so I won't be able to see any advice until tomorrow unless it;s given in the next ten minutes. God I really hope the thing's ok.
Hi
Do you have jigg? ( if you don't have it buy it from ebay or ask some friend of you )
With jigg you can enter download mode and then flash the stock rom.
Pull battery, wait 10s, then boot while holding power+vol-up+home. This should get you in recovery. Then restore nandroid.

I can't believe it was this simple, I knew power+vol-down+home got tme to downloading but I didn't know that got me into recovery. Everything's recovered now.
Thank you Dutch people!
Hi, got a galaxy s2 i19210 and using cm-10-20120926-UNOFFICIAL-i9210t
Was having a few random restarts and found that if I tweaked the voltages it would put an end to this. I found I had to use DreamKernel-GTI9210T-v1.7.1CM10-20121010073231-CWM to do this, so I downloaded it and tried to install via the rom manager.
Phone restarted to install, now when it turns on it says the usual 'galaxy s2 i9210' etc, then it usually goes to the blue cyanogen symbol spinning. Unfortunately, it no longer reaches this and the screen stays black. The lights turn on, but screen stays off.
Can't seem to get into download or reset mode with the key combination and sometimes instead of turning off the phone restarts which makes trying the key combinations a bit harder.
Have tried removing and replacing the battery but that didn't help either.
HOWEVER!
My computer recognises the phone although I can't access the hdd because the phone is locked
Odin recognises the phone
So, what options do I have to get my phone working again?
I've looked at a few threads and googled a bit but haven't found anything substantial
To clarify it's a Galaxy S2 i9210T 4G Australian Telstra phone
So I finally got into odin mode and cleared the dalvik cache and did a factory reset. Installed latest i9210 firmware via download mode and odin and everything is working again. Unfortunately I lost all my data but i'd prefer that than a brick. Still doesn't explain what happened in the first place though, did I use the wrong kernel or go about the install the wrong way? I'd like to go back to cm10 but fix the random resets.
You're more likely to get an answer here. Almost everyone here has an I9100/I9100T.

Verizon Galaxy Tab 10.1 4G LTE (sch-i905)
So I got this tablet from a friend who said it was bricked, said I could have it if I got it working. So I plug it in and it turns on no problem, strange. wiped tablet and added a couple apps. Got busy at work and the tablet drain power. That's when I got to see it bricked, but still not sure why it booted for a bit for me.
Symptoms:
Boots to Samsung Galaxy Tab 10.1 splash screen (not the animated one after), sits there for ever.
Boots to Odin update mode
When booting to recovery I get a blank, back lit screen and nothing ever.
I've tried:
-Pushing clockwork mode to fix recovery
-I've had a hell of a time finding stock firmware for some reason (it isn't on sammobile), but I did find one eventually. I pushed it to the tablet via Odin, and it was successful, but rebooted to blank black back-lit screen. Have to hard boot and hold power buttun until I see the splash screen to get that far. I followed the guide on rootzwiki reposted on icsforums - www icsforums com/forum/showthread / 13525 (sorry new member can't post links)
-Followed another guide that involved draining battery completely, no go.
I don't care what firmware I end up on, or if I can use LTE (I won't anyway)
I'm a network engineer so I'm tech savy, but not heavy on Android OS. I'm looking for anything else I can try. I saw another method involving heimdall suite, but can't find the files for my model.
Any help or guidance is greatly appreciated.

I had this problem on my gt-p7510...
What I ended up doing was wiping my sdcard..I must have had something corrupt in my file system or a kernel issue( still not sure which )..
Since you have no recovery..I think you can use odin to repartition ( I CAN NOT STRESS ENOUGH THAT THIS IS JUST A GUESS )..I have not tried it..but i will search after this post to confirm..I also believe there is a way using ADB..again not sure..
I just wanted to post this so you would know somebody was looking and to maybe give you a couple ideas to follow up on...I'll search around and see what I find
Edit...I believe ADB will only work with usb debugging checked...But you can flash a stock rom in odin with re-partition checked..you need a .pit file....I think...
Edit...Here is a link to a stock rom thread for you're device..It seems to have helped a couple people with their soft-bricked devices..just follow directions in OP..no repartition checked. I cant even find a .pit file to do a re-partition with for you're device..
http://forum.xda-developers.com/showthread.php?t=1342995 Let me know if this works for you..
Thanks for the post!! Really appreciate it.
That firmware is the one I found in the end and tried. Odin pushes it ok, but then still doesn't boot. In fact after pushing that firmware it boots to backlit blank screen, but when hard reset boots to splash screen.
I tried a pit file I found that I thought was the right one, but it failed when I used that so it must have been wrong.

I have the exact same problem as you, except sometimes I can't my tablet to boot. I know it is a software problem because before I was messing with recovery yesterday, everything was working just fine. All I wanted to do was restore to factory settings and instead ended up bricking the device... If you find / know the answer, please do share.

Did you ever get this fixed? I've had the same problem for months. I just gave up and put it away. I recently fixed a Galaxy Tab 2 and now I want to see if anyone else was able to fix this i905 not booting issue.
did anyone know the solution of this question
Hi everyone,
First of all, thanks for all the help/development done here, it is really awesome. I am new to rooting/rom so, I've spent a lot of time reading forum threads and looking at people's issues and it's been really helpful.
Yesterday, I spent all day trying to update my Bell Mobility Samsung Galaxy S Vibrant GT-I9000M from Froyo 2.2 to 4.2+
I sucessfully rooted the device, installed SpeedMod kernel(with Odin 3.04) and got CWM Recovery working when I restart the cellphone.
Afterward, I tried to update with different ROM(CyanFox, CM11, Mackay OmniROM...) but always got Status 7 error at CWM. So I figured I'd try to upate to a recent Kernel and installed GearKernel_JBPlus_Vibrant_1.0.3v.tar trought Odin. The phone got in an installation loop. Here is a poor webcam photo of the error(sry couldn't get better) : http://i.imgur.com/L3b0RmF.png. It says something like Estimating(?) volume for path [grep], Can't mount grep, Installation Aborted. Restart, splash screen, installation aborted, loop.
I had this loop at other occasions trying to update Kernel. The solution had been to put the cellphone in Download mode and reinstall Speedmod Kernel with Odin. This is what I did again.
It allowed me to get in Recovery mode but I couldn't go passed it. Attempt at restoring backup didn't worked. So I decided I'd go back to everything stock and followed this thread http://forum.xda-developers.com/showthread.php?t=1047087 and used Odin with the PIT and TAR files.
This got me in my worst position so far. If the cellphone is plugged, it loops between dark screen and the little "loading thingy" before the battery, but nothing more, no battery charge. If I try to open it without the plug, it display the GALAXY S GT-I9000 splash screen(which is weird cause I'm using I9000m) for a couple second then goes dark.. Then splash screen.. then dark... pretty quickly.
I can go in Download mode but I haven't succeeded to get in Recovery mode. I have adb on my computer but I haven't been able to call anything from it at the point I am.
I have found different threads showing different solution for various problems but I feel like I tried enough and I'd like to avoid bricking my cellphone so I decided I'd make my own post detailing the steps I took.
What should be my next step to get out of this loop? It seems like I only have Odin/Download mode to help me.
Thanks again.
If you have the gt-i9000m that is not the vibrant. The vibrant is the sgh-t959. Thats probably your problem
