A better solution is to flash official firmware using odin instead of factory reset.

Thanks. I did that and got my device back to life.

Samsung Galaxy S2 not booting

I rooted my phone without any trouble for months, and its been working just fine, until now! Then, I had to do a factory reset. The normal procedure, SETTINGS> PRIVACY> factory reset. The phone then never got past the boot logo. It starts to load, and just gets stuck at the Samsung logo, and nothing else. there's two lights glowing from the capacitive buttons, and that's all. I'm on 4.1.2 JB stock rom. Later, I tried to enter recovery mode, and did a wipe, and cleaned cache partition also. AND, the phone just sprung to life, the whole first time set up thing. I started filling in stuff and the phone just shut down again, and if I tried to reboot again, it doesn't get past boot logo. But if I wipe n do it, it happens but shuts down immediately Please help!!

Boot into download mode, get a stock rom from Samfirmware, flash it with Odin (How ? Thread stickied near top of Q&A).

stuck on twrp logo after reset

My phone is a verzon note 2 on deodox 4.3 with twrp recovery. The phone only boots to teamwin logo and flickers on and off. my computer will not recognize my phone either at this point.This is what happened. Ive been having some 4g lte loss and unstable wifi issues to i decided to do a factoty reset. when i rebooted into recovery i was stuck at the twrp logo and it would constantly bootloop the twrp logo.. I restarted my phone and did a factory reset from under the general setting. At that point it rebooted int the twrp but continued to just stay at the logo and would not go into recovery. I pulled the battery and restarted the phone but from that point on it would only boot into the twrp logo and stay there. I can get into download mode but my pc (win7) no longer recognizes the phone so i cant attempt to fix this in odin. Im not sure what to do to get this phone to work properly at this point.

My guess is that when you rooted with CASUAL, it changed the Samsung device driver on your computer and you need to reinstall the Samsung driver to get the computer to recognize the phone again in download mode.
Underneath step 7 of section 1b on Droidstyle's restore guide, he discusses issue with CASUAL replacing the Samsung driver... and he gives a link to Jeremy Loper's fix... "If odin no longer recognizes your device, most likely Casual killed the driver for odin!! follow this tutorial for restoring the driver: http://www.youtube.com/watch?v=zzghcV8HVVk"
Once the computer recognizes the phone again, you should be able to use ODIN to restore back to 4.1.2 so you can root/unlock again with CASUAL. After you get the phone restored with Odin, I would recommend booting into Stock Recovery and wiping cache/doing factory reset before running Casual again... this would enure you are starting over with a totally clean slate.
If the above doesn't work, then here's a thread where I tried to help someone else who couldn't get their computer to recognize the phone.... maybe some of those ideas will help - http://forum.xda-developers.com/showthread.php?p=55833998
Good luck!!
1 step forward two steps back. I got my pc /odin to recognizes my note 2(changed usb cords). Then tried to odin back to stock 4.1.2. At first odin kept saying (odin not responding) and would ask to close the program,after several attemps i final got it to flash the 4.1.2 file. When i flashed the file and was at the point where it reboots, it would not get past the samsung note 2 logo and continued to flicker and not boot up even when i tried to put it into download mode like it said to in this thread. http://forum.xda-developers.com/showthread.php?t=2024207. When i tried to reflash the file it failed. when i attempted again it just hangs at setupconnection. Tried again and it failed. Btw thanks for the help mattnmag.
Got it working! i simply forgot to place the sch-i605 pit. into the pit section of odin when i flashed the 4.1.2 rom.
Similar problems
I was running AllianceROM 26. My phone had been spontaneously rebooting for a bit recently. Today, it started to spontaneously reboot again, but this time, it never got past the Galaxy Note 2 screen. After pulling the battery, I tried to boot into TWRP. It just hangs on the twrp boot screen for a few minutes but never goes into twrp.
I figured I would try taking it back to stock. So, I used ODIN to try and put 4.1.2 on it and a new PIT file. That appeared to work fine. I got no errors in ODIN. However, I still cannot get this thing to get past these boot screens, either the Galaxy Note 2 one or TWRP when I try that there. I have tried this twice now, once with re-partition checked and another time with re-partition unchecked (saw conflicting instructions on that so I figured I would try it both ways). I still am not getting past the boot screen.
Any help or ideas are appreciated as right now, my phone appears to be bricked and I am out of ideas.
so what was the solution to the teamwin flashing on and off after a factory reset? this is certainly not a solution, having to reflash the phone...

Bootlooped Samsung galaxy G925Twith no solution.

I have a Tmobile GS6 Edge,My problem is this I was restoring a TWRP backup, coming from [ROM][5.1.1][OF8] OZOP EDGE. I used this Backup numerous times. But the last restore sent me into bootloop. I'm on OF8 but I ran an OF6 tar file through odin (it's the only one I can get to pass and run successfully). Heres what happened I connected my phone to computer, odin recognized it. hit start. ran successfully. rebooted, android guy came up briefly and said installing system update, then it changed to "Erasing..." then it rebooted again. Now I'm stuck in bootloop. I can boot to recovery and it says installing system update each time I boot to recovery, but selecting reboot system there shows a no command error. I force the phone to power off... power on again to bootloops.
smart switch didn't recognize the phone for a reset so I decided to go with the ODIN method and now i'm lost. I read to reboot to recovery, factory reset in recovery, power down option in recovery but I'm still in bootloop Hell. Just flashed G925TUVU3DOI1 with ODIN, same issue, wont boot past Samsung logo and now I am stuck with OI1 firmware. It will not allow me to downgrade to OF8 or OF6 for example. I have created and flashed successfully my own bootloader.img.tar file with Modem.img.tar.file as suggested. And yes im still stuck at Samsung logo. Any ideas? Please help. Update: I used the emergecy recovery option with Samsung smart switch and..... Blinking logo as usuall

HELP!!! LG LTE2 Bricked....!

Hey Guys,
I had an LG LTE 2 (F160L). I had installed CWM touch in it. Yesterday, I booted to recovery. While trying to hard reset it, I cleared the internal memory, the cache and the Delkvin cache(I still don't know what that was). Anyway, when I selected the reboot option, it asked me if I wanted to root my phone again and I tapped on YES. Now when the phone restarted, it got stuck on the second LG logo (the one with the shine. Actually it stucks after the shine has crossed). When I put it to charge it just displays
"NOTE: battery_charging_05.png is missing."
Battery 51%​
I tried to boot to recovery again but it just reboots and same happens with download mode.
Please help me guys I am stuck.
