[Q] I can't install custom recovery. It just reboots.

Hi guys! I am stuck with a dilemma if I should format my phone. I am quite aware of the dev tools as an IT student but this is the first time I've experienced this problem:
First I stupidly installed Nexus 5's Ambient Display mod without making a backup of the apk's affected resulting for I guess maybe a coincidence but I cannot install the 5.01 OTA as when I went back to the original recovery, I get the green Android logo and "Error" under.
So I flashed via the flash-all.bat the 5.01 stock firmware from Google but removed the userdata.img as I don't want to lose any of my files. It worked seamlessly. No lags, no crashes, bootloops, nothing.
Now, my problem is I want to get the Ambient Display 5.01 to run again, but this time when I tried installing CWM/TWRP via fastboot, it says okay then when I select recovery, it goes back to the Google logo then it boots normally.
What do you guys think is the problem? Should I re-flash the whole firmware? BTW I was able to root my phone the other day. So I don't know what's up. Any suggestions would be great. Thanks!
Remove the scripts in the ROM that flash stock recovery on boot. Then, fastboot flash the recovery of your choice.

Help me pleasssee

So i installed twrp recovery and did a complete wipe because i wanted to install a new rom. When trying to flash a new rom the twrp would keep restarting and wouldn't flash the rom, this happened several times. So i thought there must be some problem with the recovery so i thought of flashing it again and there it got completely ****ed up because bymistakely i dont know what i flashed because my recovery wont open anymore and it's just stuck on samsung logo and i also tried odin but my laptop won't recognise my tablet anymore even though i have all the drivers installed. So it's just stuck on Samsung logo and won't boot into recovery and i dont have an os and also my odin won't work. Wtf should i do?
Flash stock rom via Odin .
Borrow a PC to do this .

[Completed] Stuck in Boot Loop - Different Scenario

I rooted my device. Everything's all good.
I flashed a rom (xposed framework) using Flashify.
My phone started going crazy after the reboot.
Now I'm stuck in the samsung logo screen.
I need help.
I dont have TWRP Recovery or anything else. My recovery is still the Android Recovery.
I have tried wipe cache and wipe/factory reset. Nothing works after rebooting.
My option right now is downloading a stock ROM and installing it via Odin.
Problem is, I don't know if my phone is region locked and I cannot find my region/country stock ROM.
So I'm going to assume any of them will work as long as it has the same android and build version as my phone.
I cannot access my phone.
Only able to go into recovery and download mode. A normal boot will just stay stuck on the samsung logo screen for hours.
Any help is appreciated. I am very new to this, please help me.
Which device?

XZ Premium Dual Bricked Forever? PLEASE HELP!!

Got my new XZP yesterday, unlocked it fine. But Im a dumbass and WIPED THE WHOLE THING so there's No OS. No matter how many times I try to Wipe it and Flash TWRP it Won't boot into TWRP. It won't even give me a Sony Logo. It only gives me the "Your device is unlocked - Boot in 5 seconds " message and then Endlessly will do that. I can't boot into recovery. I need to know if there's a way to remedy this I'm desperate as hell cause I rooted my Xperia X just fine. I even used Newflasher to flash a new updated Stock ROM to it. Seemed to work fine, still wouldn't give me a Sony Logo or Boot into recovery.
PLEASE HELP!!! Edit: I re flashed just a system .sin and that allowed me to get back into TWRP. I still have no clue why flashing a ROM didn't work. But I have TWRP and an SD Card.

that is very very interesting... did you try flashtool and flash older android version?
Can you boot into Fastboot and flash a valid rom via newflasher?
It could be possible, that in fastboot the screen is still dark

stuck at sony logo

hi
my problem is that i wanted to flash the newest firmware which i did, but then wanted to go for more and flash existenz but forgot to fully boot the device up once so i wiped the cache and now it wont boot up, just the sony logo stays there. in flashtool im stuck at "sending sync" and my xperia companion always shows an error.
im thankful for everyone who can help me
I managed to get out of bootloop by flashing some firmware files via newflasher and actualy boot into existenz.
The guide i followed:
https://forum.xda-developers.com/showpost.php?p=72958788&postcount=16
The last time I tried my problem wasn't solved. But after I finally read all about existenz I figured out how to do it. With the help of post from yoann654 who write down everything I couldn't understand my phone runs now like it should with existenz and magisk installed.
It's really strange that even if you didn't wipe anything it works. The phone I had before this a Xperia XA it required this procedure to work
