Samsung tab galaxy 2 10.1 GT-p5100 3g
stuck in boot loop, it turns on and goes to the Samsung really noisy splash screen then reboots - AFTER trying to install a stock Samsung ROM that i suspect might not have been good. (apologies this is a project i am revisiting from a few months ago and i cannot find the ROM). It appears to not have an OS on at all now.
I have tried using ODIN to put this on: EUR-P5100XXDNA1-20140602152511 which fails at about 50%
I have also tried using sd card from boot recovery to use these zips:
ASerg.2.P5100XWALE2.NoWipe.zip and samsunggt-p5100.zip from the forums
nothing has worked and i have been stupid and not fully documented everything i have done plus left a 2 month gap between working on it.
Any way all i want to do is take this expensive paper weight and put an image that will work so my daughter can play angry birds!
please point me forward although i have been through the forums at least twice.
I have had bootloop many times, once I couldn't escape it and instructions on this website helped me:

If instructions below won't help, try to find stock ROM from another source, like
h t t p://samsung-updates.com/device/?id=GT-P5100
and flash it with ODIN.
If ODIN fails, maybe this link can help:

Fix Android Boot loop issues on Stock Android
Step 1. Remove the battery from the device and wait for 30 seconds and then put the battery again on your device. If your phone doesn’t has the remove bale battery like Nexus 4, then power down the phone and keep it powered off for 5 minutes. This will turn off your device permanently.
Step 2. After that Boot your device in to Recovey Mode. Samsung Users use Volume Up+ Home + Power keys. If you have the other Android device then do a Google search how to enter in recovery mode.
Step 3. Once your android device is in Recovery Mode, Go to the “wipe cache partition” option and select it.
Step 4. After that go back to the recovery main menu and reboot the device by “reboot system now” option.
Step 5. If the device again stuck on Android Boot Loop pull out the battery again and repeat the above steps. This time also “wipe data/factory reset” and then reboot device.
Now your device will come out of the Android Boot Loop and at the first time the device will take some time to reboot.
