HELP - stuck in boot (rooted cyanogen mod)

hi i have a samsung captivate i897. i bought it sim free from the states (u'm in uk) rooted running cyanogen mod & miui. i've had it 8months and its been perfect.
i'm no tech guru so i've never done anything else to the phone since i got it.
recently i hada problem with it forcing close on nearly application (see thread here:http://forum.xda-developers.com/showthread.php?t=1936862) but i did a little clean up and uninstalled some apps to free up space and that seemed to help for 13 days.
today i powered it on and browser forced close so i switched if off but when i switched it on again it's now stuck in (i think its called) boot loop - i get the "samsung galaxy s" animation and cyanogen mod then i usually have one that says "xiaomi" and a little music sound play. its this one that keeps looping. so instead of getting the xiaomi animation & music once then it going to the lock/enter pin screen, it just continues to repeat.
i have no idea what to do.
i tried to long press power key but nothing happens.
really hope someone can help. i appreciate any help given but please bear in mind i'm a TOTAL NOOB at this kind of stuff so try to explain things as much as possible for me.
thanks.

Yes, you are stuck in a bootloop. Just boot into recovery and do a clean install.

Download TWRP recovery for your handset. then install using still recovery mode.
TWRP installing using current recovery mode
Installation methord:-
-use Your current recovery.
-update zip file(TWRP Recovery) from sdcard.
-ok
-Reboot your mobile.
-Then install your custom rom using latest recover mode (TWRP Recovery).

A custom recovery is quite likely already installed. Just do the key combination at boot (for your device) to boot into recovery mode. You'd only need that if you want to change the current recovery.

+1. I have a HTC One X that was stuck in bootloop a couple of days ago. I think I flashed some wrong files which caused this issue. I then followed the steps in the Android Revolution HD ROM thread and voila! - had a clean install running smoother than ever! I didn't mind losing all of my data (since everything was already backed up on my PC).
Just do a clean install and your phone will work perfectly fine.

I'd suggest you to start your phone in recovery mode and re-install the software (if you cannot backup your files).

[Q] Bricked GT-P5113

I was trying to root my Galaxy Tab 2 for the first time. The process started, but failed. Now I'm stuck on the "firmware upgrade encountered an issue" screen. The device will turn off and back on, but remains on error screen. Seems to be trapped in download mode (as I can still see the download progress bar). Go Mobile and Odin say the device has connected to PC.
Anyone know of anything to fix this? Should I just revert to stock ROM and try again later?

can you actually boot in to download mode? power and vol down after power off? I know you say it seems to trapped in download mode but they're different! If you can, flash a stock rom from sammobile.com

I cannot boot into download mode. When I turn it off, it simply flashes off for a few secs then goes back to the error screen on its own. Does the same thing when I turn it back on myself. No logo screen. No droid. Nothing.
EDIT: Unplugged device entirely and retried the stock ROM in Odin. Finally worked! Looks like it might be fixed now.

I think my cord might have an issue (or they're just testy in general). I was noticing the battery wasn't fully charging for a while before all this. After the whole brick issue, I plugged it in to charge and it started flashing the "loading charge (empty battery + loading circle)" screen on and off until I unplugged and re-plugged it. I suspect that this is why the rooting failed in the first place.

Hi you may use cf auto root for gt p5113 with odin.this happend to me couple days ago.

I also bricked my tablet. Searched wide and low for ideas on how to fix. But I can't find a thing. I cannot get into Odin mode or recovery. Just hangs on the battery charging screen. My windows 7 computer can't even recognize it in Kies or odin. Yes the tablet is rooted.

[Q] not enough words can describe my problem

i think im ****ed.. i would like opininos suggestions..im desperate right now lol sounds bad i know however
first :my power button does not seem to want to work anymore
secondly: i noticed there was a basband and firmware update and i downloaded mf1 and the modem
third: i went into my quick setings since my power buton is broken and clicked on recovery mode and clicked ok
fourth: i waited .. the little blue words appeared in the top left corner as usual, and then it says samsung galaxy s3 and hangs for a minute then shuts off and turns back on.. continuing the loop.
possiblly important infomation;
my battery level was only 24 percent and i think if i charge it up or try to get it to charge that it may work out
your probably wondering what i do when my phone dies ..
well i put it on the charger and it turns on and the charging screen pops up with the battery
then i unplug the phone and it boots up without me touching the power button .
any information will be apprciated thanks ahead of time
BTW the phone was purchased the first day it was released i think the warrenty is expired
THANKS

The same power button issue happened to me a few weeks ago. I found a YouTube video of a guy who demonstrated slamming his phone on a table to fix it. Now I know what your thinking sounds stupid but it worked for me. Hold your phone so the side with the power button is flat on the table (this is how it needs to land). Then lift it and slam it down. I used a mouse pad to cushion the impact. Took like 20 tries but its been good ever since.

i forgot to mention.. i was planning on letting the phone completely die and then giving it some juice to see if that breaks the loop or sends it into normal boot mode i dont have the screw driver small enough to unscrew the back, if i did do you think holding the power button on the board will break the loop?

As I said it took me a few tries I also remember putting a crappy thumdrive under the mouse pad to get more impact on the button. Not sure how hard I did it. Oh and take your battery out.

Trust me I know the feeling. I had soft bricked my phone after I tried to downgrade from 4.3 (before the fix was found) right after I thought I found the solution my phone was doing the power loop. Scared the crap out of me.

can i update my firmware and baseband with odin ? or do you reccommend me downloading clockwork mod and using that instead of teamwin ? i want slim kat .. seems alot better then this 4.1.3 bull**** lol .. althought the bone stock rom was very very very trusty.
my next question is should i instal the firmware first hen the modem then the rom i want ?

I personally like twrp more. yes you can update that stuff with odin i think there are links in the development section. As long as you do a factory reset and dalvik format you should beable to flash whatever you want now. It is recommended to be on at least 4.1.2 modem for ROMs. If you flash the 4.3 modem make sure it is only the modem and not the full firmware. You will be on a locked bootloader if you do.

I have exactly the same problem now. I tried to update a kernel via TWRP and now boot loop. I can't even get into download mode, let alone recovery mode, just reboots automatically when hold the power button down.

I don't get into download mode at the first try i keep trying many times, maybe it's the same thing for you too. apparently i need to flash stock rom with odin on download mode, that's what you should do too if you get to download mode.

I have same problem...

Noobie here, and not sure if I know enough to make much sense.
I had a similar situation occur today.
New to me but a 2nd hand p600 which rooted today and then I used Odin 3.10.6 to flash TWRP and found myself in a boot loop similar to the description.
I panicked bigtime and feverishly googled my way to to this message thread and my hopes were raised when I read the OPs message and then got dashed to find no solution posted .
After perhaps 20 attempts of getting combined button pushes and releases correct. (it never happened ) I was desperately trying almost anythiing and then got to TWRP File manager, then Reboot, then System, then Normal Reboot and finally Success! I got the regular reboot. Phew!
Hope it helps

Well, I let it sit over the weekend and the battery complete depleted. I was then able to get into TWRP and Download mode when I applied power, I have since flashed a new rom and whewwww, up and running again. Before the battery went dead, it wouldn't do anything but reboot.....

Galaxy Tab 7.7 (P-6800) not booting into Download Mode

STORY
I installed a stock ROM for my Galaxy Tab 7.7 (P-6800) and it was stuck at the flashing SAMSUNG logo (the one with the tune) and so I just left it there and went to sleep. The next day I tried turning on the tablet but it didn't work so I booted into Download Mode and did a NAND erase. I was planning to install a stock ROM from SAMMOBILE but now I can't boot into Download Mode. When I try to, it goes into the warning screen and after a second or so, it becomes black. I figured it could have been out of battery or a button is broken. I have tried charging the tablet with wall charger (2.1A) but it doesn't seem to work. I could occasionally get it successfully into Download Mode but it will turn off itself for no reason.
PROBLEM
THE PROBLEM IS THAT I CANNOT BOOT INTO ANYTHING NOT EVEN DOWNLOAD MODE SO PLEASE DON'T GIVE ME GUIDES ON HOW TO FLASH.
I'M ACTUALLY LOOKING FOR A GUIDE ON HOW TO ENTER DOWNLOAD MODE WITHOUT USING PHYSICAL BUTTONS.
THERE IS NO ROM INSTALLED SO DON'T TELL ME TO GO THE TERMINAL OR ANYTHING. IT IS ABSOLUTELY EMPTY ONLY HARDWARE AND DOWNLOAD MODE IS INSIDE THE TABLET.
Anyways, please help. I am trying to get daniel_hk's cyanogen mod on this for my friend and I don't think he would expect me giving a bricked tablet to him.

Dead battery maybe?
Do you guys think I joined the dead battery club?
