Soft bricked OPO - Stuck in Fastboot mode

Hi. I dropped by OPO recently and had to replace the screen + digitizer myself. After doing it, i decided to wipe my phone and re-install Android again. I did a factory reset, flashed a custom rom, gapps and a kernel and i am not able to boot into the OS. When I reboot the device or power it on, I always end up in the Fastboot mode. I am able to get into recovery, but no matter what I flash, whenever I hit reboot into system after flashing, the phone goes back to Fastboot mode.
When in Fastboot mode, I'm able to flash stock images of 44S , but any reboot doesn't take me to Android, it keeps pushing me back to Fashboot. Flashed multiple TWRP versions, tried restoring to 44S/38R through fastboot, but none of them work. Any restart takes the phone back to Fastboot. Any ideas on how this could be fixed?
Any help is much appreciated.

[Q] How to get out of boot loop ?

I have a device that has a non-removable battery. Suppose that when testing a ROM I messup and i enter bootloop (Or get stuck at boot logo) , would I have to wait for the battery to drain completely ?
Can I flash a ROM into my device using ADB ? And can ADB reboot my device , even if its in bootloop ??

Just keep the volume and power buttons pressed to go into recovery.. Recovery mode is accessible even in a boot loop . Then wipe and flash again!
Hope it helps!

if the keys dont work then your phone resets a diffrent way.
just google your phone model and how to hard reset. gook luck OP!

Try different button combinations...
If all else fails, just wait for the battery to drain, charge the device when powered off and try flashing again
Hopefully your device will work soon

Try flashing the stock ROM and re flashing the custom ROM.

Yes. Flash different ROM for your device. You can also boot into recovery while in a bootloop.
And yes adb may reboot your device!

YU Yureka with no OS stuck on a Bootloop and unable to enter recovery mode.

Hey guys!
So, i was trying to install CM13 unofficial version, and wiped the system and internal storage using TWRP recovery. I was supposed to install the rom from a zip file i had placed in the external memory card. What i did, was, i rebooted the phone by mistake, after wiping it from the recovery without installing the ROM and now the phone is caught in a bootloop. I know i am an idiot to do that. I tried removing the battery and reboot it in recovery mode using the key combination with no luck. It just starts the boot loop. I tried using fastboot and adb from pc to push files into the internal memory, but my device is not getting detected on the adb anymore (maybe the usb debugging is disabled now?).
What i guess is stopping TWRP recovery from showing up is the lack of twrp/themes folder in the internal memory since i wiped it. But there might be some other cause that i am unaware of. What do i do now? Any help will be greatly appreciated!

Hey! I'm having the same problem with my yu yureka.. Can anyone help me please!

Hi! I'm having the same problem with this post... Does anyone knows the solution of this problem. I'd be really glad if anyone could help me with this..please!

Hey are you able to boot into fastboot mode? If you can....
Prerequisites –
1. Make sure that you have 70-80% battery on your phone.
2. You need a PC and a USB cable to connect your phone to the PC.
3. Flashing the factory firmware will wipe all the data present in the internal memory. So, make a backup of that if you can.
4.Install all the necessary Device drivers.
DOWNLOADS -
1. Download the flash tools from here . http://www.mediafire.com/download/87gfz7mdch188an/Flashtools_For_Yu_Yureka.zip
2. Download the factory firmware from Here (cm 12.1) . http://builds.cyngn.com/factory/tomato/cm-12.1-YOG4PAS3JM-tomato-signed-fastboot.zip
Steps To Flash Factory Firmware –
1. Extract the flashtools zip in a new folder on the desktop.
2. Extract the factory firmware zip in the same folder and make sure that all of the flashtools files are also present.
3. Now, power off your phone. If you are stuck in a bootloop, then pull out the battery and reinsert it. (Do not switch on the phone.)
4. While pressing the Volume Up key, connect your phone to the PC with the help of a USB cable.
5. You should now see the fastboot logo on your device. If you did, leave the Volume Up key. (If you do not see the logo, retry the process.)
6. Now go to the folder where you extracted the flash tools and factory firmware and run the flash-all.bat by double clicking on it.
7. A command window will open and the flashing procedure will start. (Make sure that your device does not disconnect from your PC during the procedure.)
8. The command window will automatically close once the procedure is completed.
9. Disconnect your device and boot it up by pressing the Power button. (Since this is first boot after flashing the firmware, it may take upto 5 minutes.)
Done you should be back on cm 12.1

I flashed the factory image via YGDP tool as well as fastboot. But it boots upto a point and then goes in bootloop. Also if i wipe data/cache still it makes no difference. Also unlocked bootloader and twrp also don't load up. Again goes in bootloop.

Hi, I flashed my Yu Yureka AO5512 Yesterday and entered into recovery mode and selected the wipe userdata option. When it was doing the process after 20min the process stopped all together and My phone does not start at all now. If i press any button there is no response at all. Looks like phones OS and everything is wiped out. How do i go about from here?

Sorry to hear that anyway,
By stock lolipop you mean you had the yureka plus with Volte From factory right!!...if so the twrp might have been for the yureka plus with the cm bootloader which got replaced in the new Devcice

I am facing the same problem and in my case I dont think its an battery issue...I was happily using the CM 13.0 Snapshot Rom since a long time...but today morning when I did a soft reset by going into the settings in my yureka...the phone has gone in bootloop...and nothing is working...using fastboot I even flashed the twrp again and also flashed the CM 12.0 Stock firmware..but nothing is working...after the YU logo it restarts....please help...

I am also facing problem maybe worst
I dont know what wrong I am doing but I am getting "FAILED (remote: unknown command)".
Few info:
1. I get my device ID when I do "fastboot devices" but nothing on fastboot -i 0x1ebf oem device-info".
2. Also for my YU5510A fastboot screen doesnt say' "fastboot" it says "Information do not unplug the cable - Secure Phone".
3. I have red light on, phones keeps rebooting 4-5 times than red light goes off and charging stops.

Ignore that and use other fastboot commands and go ahead, as your device is being detected in fastboot mode.

But when I am executing other fastboot commands it halts the process between with error "FAILED (remote: unknown command)".
I have read about this error and people suggested that I need to get into "Download mode" not "fastboot/bootload". To get into "download" mode I tried pressing "VoulumeDown+Power+Home", but nothing happened, it simply restarted the phone.
Please advise.

Stuck on bootloop.

I'm using Lenovo K6 Power... And wished to use custom ROM. So did all the procedures(ADB, TWRP, SuperSu, ETC). Now, at the time of installing custom ROM you have to wipe all data including your phone's UI (ROM) so I did that. Now I tried to Install that custom ROM several time but it didn't install, I don't know why. So I clicked on reboot button... And then boom... My phone is stuck at Lenovo logo. I know I made this mistake. I didn't understand that, How can a phone reboot if it's original OS is deleted.
It can't even enter in TWRP recovery mode. Fastboot can be seen sometimes.
So please me with this, I'm completely new in this. Read so many forums and watched so many videos on YouTube for this. But they didn't help me. Any help will be appreciated. Thank You.
Highlights-
1. Stuck at Booting Animation.
2. Can't enter into TWRP recovery mode any how.
3. Fastboot Appears on top sometimes.

If phone gets powered on, then its bootloader get run ( comparable to UEFI/BIOS in Windows computer ) what , when its tasks have finished, tries to start/run Android OS.

Is not bad: many do not understand
Eeach mobile device can get run, but without an OS it stops after bootloader finished, because it's just a box of bits.

simple
when bootloader shows up, or bring it up with key combinations, connect phone to PC, and in fastboot/bootloader (on phone) type
fastboot reboot recovery
or if not work then:
fastboot boot c:\twrp.img
and do the rest via twrp, like flashing custom ROM again, or just flash stock ROM

Thank you very much mate...
My phone was successfully recovered into TWRP recovery mode. But now the problem is...
While installing ROM it is showing 255 error.
Any suggestions...

Question [ Solved ] Stuck on MIUI Recovery 5.0

Hello this probably caused by bad rom installation, I've tried to get into fastboot mode by holding down volume button but it just boot looping there I've also tried wiping the data from the recovery menu but it doesnt do anything I've also tried using ADB and MI flash but both of them seems useless since I cant get into fastboot mode there's also Mi suite pc but my phone just doesnt connect with the pc. Is there anything I can do without going to service center? I'm abroad rn and my warranty will be void if I'm using outside service and I dont want to go outside without phone. Also my power up button seems to be busted
: I just select help from MIservice and boot it to bootloader using adb I manage to install twrp again but after I install rom it still wont boot into android

Do clean flash. Start from step 14.
Recommend to install MIUI 12, boot into MIUI to make sure your phone works well with SIM card readable.
After phone successfully booted into MIUI, then you can flash custom ROMs.
