I installed the latest nightly build (cm_galaxys2_full-88.zip) on my phone yesterday night and restored the all the apps through Titanium Backup. Everything was working fine until this morning I tried to create a backup using CWM recovery in Rom Manager. The phone shut down and has since been stuck on the initial boot screen (one with the Samasung galaxy S2 logo). It does not boot into recovery mode using the button combinations. I can only get it into download mode but Odin does not recognize it as I thing i forgot to enable USB debugging.
I have tried removing the battery and rebooting and also tried to access it through odin a number of times. But nothing seems to work.
What am I missing here ?
This might help?

The bootloop began when I was attempting to flash the cyanogen7 with the google apps.
I read every post in this thread, and have seen a number of people who cant boot into recovery, but can boot to download. I haven't seen anyone else mention that their phone is no longer recognized by odin on their pc.
Please help.
edit:
Perhaps odin doesn't see my phone because I didn't have USB debugging enabled? if that's the case, what can I do?
------------------------------------------------------------------------------------------------------------------
solved:
heimdall overwrites a driver and stops odin from seeing your phone. i attempted to remove it, unsuccesfully. but loaded odin onto a different computer (that had never seen heimdall).
i booted into download, connected to 2nd pc w/ odin, and ran CF-Root-SGS2_XW_NEE_KI8-v4.3-CWM4.tar (search forum) in PDA. this made my phone bootable again.

Thanks. Although that did not do what I expected it to (due to some license issues), but it got me into recovery mode from where I could restore a Nandroid backup. Am back on RevolutionROM for now. Looks like CyanogenMod will have to wait for me.
I experienced the very same thing for the first time today. Had checkrom revolution and ran rom manager to backup and am now unable to boot into recovery/download. Will try to hook it to odin then
I know there has been other treads about this before but none of the suggestions seemed to work for me. I searched and searched and I'm just not finding a fix. I hate to do these posts when an easy answer is right there but I just can't figure it out and it's killing me. So here it is:
I just got this Verizon Galaxy Tab that would not come on - only showed the battery charging icon. I just charged it over night and it came on once. However, processes kept shutting down. For instance, when I went into settings and tried to connect to my wifi network, the whole process would just close down. So I let it get to about 40% and reboot it to download mode (there was no recovery). I found the correct .tar file for it and flashed it with ODIN3 v1.85. It completed successfully but now it won't boot past the Samsung splash screen. Once the splash screen comes up, it will just go back to the large battery charging icon in the middle of the screen.
Then I tried the other option where you get into recovery and nothing happens at all. The screen is backlit black (you can just see light around the edges of the screen) and nothing ever happens.
So now, it's just charging but it seems to charge very slowly. I was wondering if this is a battery issue or some strange sequence that needs to be done. It seems to be at about 40% again. Any other suggestions would be appreciated.
These are other things I've tried:
hold the power button down for 30 seconds
Hold the power button down while touching the screen
More suggestions would be appreciated.
Now the tablet is fully charged but it still gets stuck on the splash screen when trying to boot up. Still have no recovery. Also, I'm not able to find a PIT file to re-partition. Can someone tell me how to get the stock recovery back at least? I've been looking but I can't find a file to flash for the recovery.
Same problem
Hi, I have the same issue basically. I have the Galaxy Tab SGH i957D 8.9 (TELUS) and flashed it to root last night, now I have the same problem. Except I have CWM installed, I was able to install that AFTER I locked it up. Help from one of the GURUs here would be great. It's obviously a problem caused by flashing it.
So try flashing with CWM, at least you'll have a good recovery on it. If we work together, we may be able to come up with a solution for our dilemma. I don't believe it;s a major problem, I had the same issue with my captivate phone when trying to CWM and Cyanogenmod, and I got it working perfectly, so there is hope.
I have tried the stock rom, rooted rom, and a couple of others, but still can;t get past the splash screens. Left it overnight trying to boot, and all it did was kill the battery. I can;t even turn it off, it just reboots every time I try shutting down. I CAN get to download and recovery mode though, and flash it all I want with Odin 3.7 and 1.83, just never boots past the splash screens.

Thanx for the reply. As you can see, I've been around these forums for a long time and usually I'm able to work it out but this one has got me stumped. Just wanted to ask you if you have tried to flash a custom ROM in Clockwork? Also, did you go through unlocking the boot loader befor you flashed it? I did not because I received the tablet in this condition. I tried to flash clockwork mod but I get an "invalid file" error in Odin. Once I flashed the stock recovery and it worked fine. But after reflashing the stock rom, the stock recovery is gone now. Do you have a link to the files you used? I'm thinking that the stock recovery is messed up but I can only find that one file.
no I haven't tried flashing through CWM, as I wasn't trying to flash originally, I was just rooting and going easy on it, then it wouldn't boot, so I wasn't prepared and now can't add files to my SD drive.
I didn't unlock the boot, as none of the instructions I read mentioned it (rooting was all I was trying to do).
I don't even have a stock recovery either, all I have is CWM and TWRP.
I'm going to try mounting it in Linux and see if that makes any difference to put roms on my SD drive, as windows doesn't like it anymore, except through Odin, where luckily it seems to work fine... For now.. lol
Fixed!!!

I'm glad you got the right firmware and fixed your tab! But this site does not list a firmware for the SCH–i905 anywhere. Unless the Verizon Galaxy tab has an alternate model# there is no firmware on the site for my device. Oh well, at least one of us got tablets fixed. Congrats!
Download mode issue.
What recommendations do you guys have for a tablet that will not recognize in download mode?
I accidently flashed a bootloader and had auto reboot on - couldnt flash kernel and modem in time.
My tablet fully boots up, (rom manager says cwm is installed) as well as when i boot into recovery its completely black.
My main concern is that download mode is not recognized. it was previously working prior to installing the bootloader.
What can i do to fix this issue?

Can you start by giving as much info as possible about your tab, make model# etc.
can you actually get into download mode? Power button and Volume down button till it boots then release pwr.
you may have bad drivers on your pc. I had this problem with my phone when I installed CM.
get into DL mode and then start Odin and hopefully you will see the Com port attached.
then in PDA load the stock rom for your tab.
hopefully at this point youll be all set.
if your tab is fully functional, then try just flashing CWM or TWPR to your tab. I found with mine that CWM works best. I like TWP better for looks and the touchscreen functionality, but I found it gets a bit flaky after a few flashes, where CWM seems more stable.
SHAWNDH...
give me all your info for your tab, make, model.. carrier etc. as much as you can, and I will see if I can find any stock roms while doing my searches. 2 sets of eyes are better than one...
So i have a sch-i905, 4.0.4 - I CAN boot into normal android
I flashed a bootloader last night and had auto reboot ticked. was not able to install the modem or the kernel.
I can get into download mode without any issues,but now download mode says "waiting for cable" and is not recognized by pc as it once was prior to the flash.
I can also get into recovery but its completely black ( assuming due to no kernel flashed )
I can get into android normally, but cant fix firmware through download mode, and recovery.
Please help :X
side note: rom manager says twmp and cwm is installed, though i get no display in recovery only blackness
if i can get download mode to work again or get cwm to show up i can fix it, but dont know where to go from here.

I don't get it. First, you can't flash a kernel using Odin. Second, your tab won't even be able to boot without the kernel.

If you can get into DL mode, then its probably just an issue of drivers on your pc. Download the samsung drivers and reinstall.
Then put your tab in dl mode. Then connect to the pc with cable, try a different usb port than before.
Then start odin, if you get the Com port showing up in the status box, then flash CWM recovery to the tab. Then start over with what you are trying to do. But I can almost garantee its an issue with drivers on your pc. I had the exact same problem with my phone when I did it,
and fixing drivers was the issue. I wss stumped for a long time on that issue. If that doesnt work, look into Heimdall flash utility or Kies and go from there.
Hope this helps. Or at least gets you on the right track.

dont think its a driver issue.
it was working fine in download mode prior to me flashing a bootloader.bin, and yes you can flash a kernel.bin through odin, as well as a modem.bin.
I was in the process of installing cwm this way when it happened.
I can get into the os, i can get adb working fine, recovery is just a black screen though it goes into it. and i can get into download mode still, just stuck at "waiting for cable" no interaction with device manager

Ive tried another pc as well. I dont believe its a driver issue as there is 0 interaction in download mode with device manager. but prior it easily was detected in odin no issues.

Ok... Im getting confused here... You Can still flash with Odin? Then you can install a new recovery on it. If device manager on the pc is not working, then you probably have a corrupt install, or the wrong rom file for your particular tab, and the usb drivers arent correct for your tablet.
Personally, I would start by downloading a stock rom file and return the tab to factory before starting anything, so you have it working as it should before continuing further.
If you DO HAVE a stock rom, maybe you could pass it along, i believe shawndh who started this thread is in need of one for the same tablet.

I cannot currently get download mode to recognize anything. just keeps saying "waiting for cable" thats why i cant do anything in download mode. It was currently working prior to flashing the bootloader through odin with the "auto reboot" accidentally clicked.

Oh... Well then it is beyond the scope of any problem I have encountered, or seen a solution to. I thought you could still connect in download mode.
Can you change usb debugging mode in tablet settings, that may enable you to connect? If not I dont think I personally can help, as your posts read like you could still use Odin.
On my phone, (galaxy S) nothing would connect after I messed up, but could do things with Heimdalls utility. See if you can connect with that. Worth a try, it does the same as Odin, but connects differently somehow.

i even went as far as getting a brand new cable to see if it was my cable still same thing. No response in download mode for either pc's ive tried.
little stumped....
possible clues: when tablet boots up, it boots up to a bright black screen, only once it completely boots up am i able to see my display properly.

Thanx for the reply. I have the SCH-i905 32gb Galaxy 10.1 tab. The carrier is Verizon. I've spent days looking for another download source but I can only find one - there's a link from this site. Others have posted that it did restore their devices so I'm thinking that there are some bad clusters that need to be quarantined but I can't even find a tool for the Galaxy Tab that will do or check for that. I'd appreciate it if you could take a look though. Thanx.

Are you connecting to a USB port that is on the motherboard of your computer? Mine will only recognize my tablet with one port. The other ports are not recognized at all by ODIN.

I don't think its a cluster issue, just a bad flash previously. But you'll see from the link, yours is also known as the P4vzw. Well check the link and make sure that's your tab that I found. Then have a look at ALL the files for that tab.
Have you seen/tried this one... here's the thread STOCK ROM FOR YOUR TAB...
forum.xda-developers.com/showthread.php?t=1342995
Here's just the file.
http://goo.gl/XPMXv
Try flashing CWM recovery to your tab, and try a file from cyanogenmod
http://wiki.cyanogenmod.org/w/P4vzw_Info
Or just try the CM ROM first maybe and see what happens. I don't remember what you have for recovery. There are a bunch on there, but all nightly that I saw, but even that would be better than nothing for now if it works.
I'm still looking, but I know what you're saying about few and far between. I think they all are for the tabs. Let you know if I find anything else.
