[Q] Cannot Boot into Recovery, Android O.S is Messed Up - Nexus 7 Q&A, Help & Troubleshooting

Hi,
The other day, I flashed a new ROM (after clearing everything) and it has messed up my entire device. My device gets stuck at the android logo and stays there forever when booting into Android. I cannot boot into recovery mode, it just gets stuck at "Google".
I also cannot boot into recovery mode using Nexus 7 toolkit because it requires my device to be booted, which is impossible.
Anyone know how to fix this?
Thanks

[Q] Stuck in Bootloop with non working recovery...

I have a big problem at the moment... I wanted to boot into recovery mode, then an android icon with a red exclamation mark appeared. After I tried to boot into the recovery again using Power + Volume Up, it appears again. Since then I can't reboot my Nexus 10 normally. Bootloader says:
Reboot Mode Flag: Recovery
I think my Nexus 10 is always trying to boot into recovery, but this is no longer working... what can I do to get it work again?
Hope someone can help me with this
Edit: I could finally solve my problem I used fastboot to flash a new recovery that is working, after this I rebooted into recovery and restarted the system. Because this wasn't working, I had to get back to factory settings, but it is working

GT-I9505 Stuck at Boot

I decided to unroot my S4 seeing as though a rom I had flashed was screwing around with my system. I eventually was able to flash a stock rom via kies, but now the phone is stuck at the boot screen (Samsung logo with blue light).
I have tried booting into recovery mode, but for some reason after 5 seconds, it just ignores it and goes into standard boot, something that it has done since I flashed the bad rom.
Would anyone know a fix for this?
Thanks in advance.
An update. I managed to get into recovery mode but instead of the normal android with the blue square, the android is on the ground with a red triangle. I've wiped cache and data, but still getting stuck at the boot screen.
Some help would be appreciated.

There is a 50/50 chance that if you go back into twrp/cwm custom recovery
and do a "factory reset" it would boot up normally unless you also wiped
"system".
Good luck!

Flash a stock firmware using odin in download mode then see if it reboots
If not go to stock recovery after that factory reset and wipe cache reboot

[Q] Slimbean stuck at boot animation - recovery broken

I have an MB525 running Slimbean. I took the battery out mid boot the other day and now it won't progress beyond the boot animation.
The system is responsive, and when connected via ADB I can make changes. Tailing logcat just shows frequent garbage collection.
What is the best way to recover this? I've booted into recovery (vol down when blue LED), and if I select Team Win Recovery - nothing happens, selecting CWM recovery just causes it to boot as 'normal' (ie stuck at boot animation).
I'm not familiar enough with the boot process on this to know where to start adb pushing files to fix this. I'm aware that I could bring it back to stock with RSDLite and start again, but considering I have root access via ADB, I was hoping that there'd be a better way to do this.
Ultimate goal is to install CM11 or Slimkat.

Brick and Restart Loop no Download

Hi,
I was on a rooted android 4.4.2 official, when i tried to install custom recovery using Flashify.
https://play.google.com/store/apps/details?id=com.cgollner.flashify
There was the Secure booting error and booted normaly.I found out that this was not possible so i quit.
Today a got an update from LG so i installed it. The phone rebooted giving the Secure booting error, and it stayed black screen.
Googling i found this tread
http://forum.xda-developers.com/showthread.php?t=2582142
I folowed it but i thought since my phone had problem with it's recovery, just flashing the recovery.img would be ok.
I restarted the phone bat it would not start. It desplays the lg logo restarts, lg logo restarts.
I can boot the recovery but it does not work. When i press recover it just restarts.
I cant boot download mode or anything else, i have been googling the hole day.
I would apricciate your help. It is a one month old phone.....
Thanks

are u stuck in cmw recovery??
Stock recovery.... :/
Sent from my GT-I9100 using XDA Free mobile app
Same Problem here! Exact Same
Also having this issue, stuck in the secure boot loop, can't get to download mode.
Im exactly the same - im stuck in TWRP and cant boot into Download mode at all - just get the LG Bootscreen then straight into TWRP Recovery no matter what i do
Did we all except some kind of update from LG........ i wonder if this the link here and is now a common problem?
Mine was this and i thought it was just an app update for the stock apps and now im stuck big time
Any luck guys or solutions then please post here so we can keep it together and help each other!
Yeah I got an OTA update for my D803-Bell model, upon restart entered the secure boot error loop.
Sounds like, via this thread that it's commonly happening to people who had TWRP or CWM (or even aborted / possibly never completed installs like me) got nailed.
As per that thread, and everything else, I've tried every option possible -- no download mode. Recovery mode doesn't restore anything, just resterts to lg logo -> secure boot error -> black screen. Shows as QSHSUSB_BULK in windows/linux, and I can see those 25 partitions in linux (but reflashing openrecoverytwrp__.img over the recovery partition didn't help. I'm waiting to find out how I can make my own copies of those various partitions listed, from another D803-Bell model I have access to. All the D803 .img files on those links in that thread, appear to not contain D803 Bell stuff, just Telus, Rogers, etc... so I'll likely have to source my own.
I just took a shot in the dark recommended by a friend -- and fixed my phone.
I zeroed out the 'fota' partition on the phone. As seen in this thread ; http://forum.xda-developers.com/showthread.php?t=2451696
Just did a dd if=/dev/zero overtop of the fota partition, which was 25 for me from my linux box. One quick power cycle later, and I'm fully functional again, and the OTA update that killed me is still showing as available again.

My SM-T515 is stuck on the TWRP logo and i can't do anything.

So, I wanted to root my device using magisk but i failed and tried to install TWRP. After installing it, I restarted my device and tried to get into TWRP only to get stuck in the logo screen. All I can do is restart the device, I can't get into download mode and stuff like that, nothing works at all.
I left the tablet overnight and it is still stuck on the logo screen, any help?
EDIT: I have managed to break out of the boot loop by following petapen's instructions inhttps://forum.xda-developers.com/galaxy-tab-a/how-to/galaxy-tab-sm-t510-stuck-twrp-3-3-1-0-t4075359! Problem solved!
