[Q] Phone Bricked - Might not be hard bricked

Hey all, today I unlocked my bootloader and s-off'd. I decided to install 5.0 GPE and convert to GPE. Afterwards, I was stuck in bootloader. I flashed TWRP to recovery and tried multiple roms to no avail. Then, TWRP started flickering and crashing. In a moment of stress and anger, I thought, hey, maybe it will work in the boot partition. I was wrong, and now I'm in a boot loop. I can't get to bootloader no matter what, and it just keeps showing the google screen, then the TWRP screen flickering, then reboot. Any ideas?

If it's in a bootloop press and hold vol down button which will take you into bootloader.
OR
hold power+vol up upto 10 seconds , as soon phone restarts press and hold vol down which will take you into bootloader.

Broken android when trying to enter recovery

Hi!
Today I unlocked bootloader and installed a custom rom and everything went fine.
Now, when I tried to flash the camera mod app, I couldn't enter TWRP. When trying to do it with the restart option it shows a broken android and I have to remove battery to get the phone running again. Manual (holidng down vol button + power button, as well as holding down buttons and releasing them for 1s) is also not working.
The phone works fine, but I would like to have TWRP working.
Can I just reinstall twrp like the first time?
Thank you

What device? H811? Needs to know more about what software you flashed.
If you can get into fastboot you can push twrp there.

Hmmm i flashed xperia phones locked bootloader twrp on my h818 and i got this error too so it means it changed the recovery but can't start it?
Sent from my LG-H818

H815 EUR. I installed the 2.8.7.0 and the 2.8.6.1 from https://dl.twrp.me/h815/. I tried it multiple times with these 2 versions and everytime I get the same error.
Connecting it to pc and entering recovery works without a problem, though.
Edit: I flashed Genisys 3.7

So you can get into twrp with "adb reboot recovery"?
Your problem is you can not access it from neither the rebooter app nor the hardware buttons?
When using the harware buttons, hold vol down then press and hold power until the logo shows up. Release power for a second then press and hold again.

Correct, I can get in twrp with "adb reboot recovery"
I was releasing both the volume and power buttons. Tried it again, but I came to a menu where I could only choose whether to delete all data (factory reset) or not. When choosing NO, the phone proceeded to boot normally.

That menu is perfectly normal. You have to select okay. Because you have a custom recovery it will not factory reset your phone but rather boot you into twrp.

OnePlus 3 Will not boot after Flashing RR

Hi! So I have been rolling with the marshmellow version of RR for quite some time and figured I was due for an upgrade. I went to update to the Nougat version, and did everything correctly, firmware, wipe, rom, then gapps. Much to my dismay I was greeted with a screen prompting me for my pattern to start android, I thought this a bit odd but went with it and my pattern did not work. I tried again thinking I may have done it wrong but nothing worked. I didnt think much of it and went to flash again to make sure I did it right, but my recovery never booted. Afterwards I got an error that was very quick and I was not able to read. It came just after the "your phones bootlader has been unlocked" etc. It was a very similar screen as well. After this, I was not able to boot up the phone at all. Once I was able to power up the phone but it simply gave me the same error and now its not starting at all. Any help would be much appriciated and thank you if you made it through this post.

First of all, you need to flash the very latest version of TWRP. If you are suffering from encryption issues and cannot decrypt TWRP, you will need to press back on the TWRP screen, and press wipe -> Format data
You will lose all your data and will be unencrypted. Make sure you have the latest TWRP, as this is vital for Nougat.

Thank you for the help, but I cannot even get into my device to update TWRP.

Try holding the power button for a minute, or try volume down + power to get into the bootloader.

Already did, it doesnt work. Black screen.

Im facing the same problem too. Cant even get adb to work ?

If you can still get into your bootloader, use fastboot commands to flash the latest TWRP.
Either hold Vol Up + Power when you phone is off, or turn it on normally and click any volume button during the "bootloader unlocked" warning screen to access the boot menu.
If you can't access the bootloader at all, then I believe the unbrick guide is your only option.

I can get to the bootloader, but when i flash recovery, it just restarts again and again.

Wipe the recovery partition first before you flash the new one.
Also, what version of TWRP are you using?

Yeah I will look into brick guides. Also going to try and let my phone charge to see if that may help. As far as I can tell it isnt charging but I might as well try.

Thank you for all the help guys, eventually what worked for me was indeed an unbrick guide. I will now be sure to read up entirely on what exactly I need to upgrade to fix this issue. For any wondering https://forums.oneplus.net/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-3.452634/ This was the guide I used to fix my phone.

Stuck :( TWRP flashing screen

So I was trying to install TWRP on my phone. I have a Mac and was looking at some online guide. I had a pin set-up, and this is what I did:
1. Installed ADB and fast boot
2. Unlocked the boot loader on the phone
3. Check the terminal commands that the device is connected correctly
4. Had the ABD and TWRP img files on the phone.
5. Tried to fast boot TWRP.
What is happening now is that I'm stuck on a boot loop of a TWRP screen, the screen if flashing and won't load. I'm guessing to let the battery die out over night
I was looking at a few threads and some say that I should flash the factory image. Everyone is saying flash the stock file... However, I can't even get the phone to turn off or go back into bootload mode for my computer to recognize the phone.
Any tips?

Hold volume down and the power button down. Keep it held down might take sometime but you should get to the loader. boot twrpRC1 flash rc2 after getting in twrp. You could also start fresh by fishing factory once you get back to bootloader

Long press power button to shut it off
or press power button and vol down together and will take you to fatsboot mode and from there you can use volume button to seltect bootloader or recovery

I don't do pin's so I'm not familiar with the hangups involved with those and TWRP.
But I guess the first thing I'd do is remove the pin lock.
Then power down phone.
Wait 30 seconds!!!!!
Press power + volume down until phone powers on, then let go.
Should boot right into bootloader.
Fastboot boot twrp.
Install TWRP from the fastbooted TWRP.

I'm not familiar with the Mac process but on a PC we need to fastboot into TWRP from an image file on our computer first, and then flash the file on the phone.

I recommend keeping a copy of the boot signer on your device, flashing this fixes most of these types of issues I have found, especially with new rom upgrades etc.

Did you let the phone fully boot into the system after unlocking the bootloader, or did you immediately try and boot twrp?
I've had this problem twice before, both after a fastboot unlock, and I had to let it fully boot into the system before proceeding

Thank you you too. That was the problem, my patience. I didn't hold it down long enough for it to boot back into boot loader mode.

Hey I think that was it. I immediately tried to boot twrp without letting the system fully boot.
Thanks you all for the support. Go XDA!

The first question everyone should be asking is if OP was on the O Beta previously.. If that is the case Op needs to flash the factory image in both slots.
Put phone into the bootloader
Flash all bat
Put phone into the bootloader
fastboot --set-active=other
fastboot reboot bootloader
flash all bat
fastboot boot twrp
Even if OP wasnt on the O beta, this should fix the issue.

After successfully flashing Oreo, I am seeing the same flashing/looping TWRP (twrp-3.0.2-0-RC1).
Long press of Pwr restarted the phone.
Rinsed & repeat a few times.
Any thoughts to flash TWRP (temporarily)?

Can't flash custom recovery

Hey everyone. I'm a novice at this, but I've gotten tired of Xiamoi's updates and decided to try Pixel Experience I downloaded the latest version of TWRP and flashed it per the instructions on the website. I know that unless I boot straight into it, it'll be overwritten by the stock recovery, but that doesn't seem to be possible. Both power + volume up, and adb fastboot reboot recovery just take me into a boot loop until I hard reset. And then of course, the stock recovery is back.
I tried Orange Fox, and various other versions of TWRP, and the same thing happened. This phone really does not want to boot into a custom recovery.
This has been a difficult question to google as everyone just gives obvious solutions like "reboot straight into recovery!!" I'm hoping someone else has experience with this.

If you install PE successfully it won't overwrite your current recovery. As far as I know only stock MIUI removes custom recovery when it boots into system.
To boot into TWRP with the phone off press and hold volume up + power button. When the Redmi logo appears release only the power button (keep volume up pressed). When the TWRP logo appears you can release the volume up button.
Ignore the root part if you don't want it.

The video mentions using the button combo if you're on MIUI 12. Press and hold volume up + power button. When the Redmi logo appears release only the power button (keep volume up pressed). When the TWRP logo appears you can release the volume up button.

I don't have PE yet, I'm still on stock MIUI. I'd like to switch to PE but I can't get into TWRP or any other custom recovery.
Also I have tried this several times-- as stated in the post, volume up + power just sends me into a bootloop, and the next time I restart, MIUI is able to remove the custom recovery.

Sorry, I mistook your post for the same couple suggestions I'd been given, and was way too quick to write it off. Using the downloads in the video description worked like a charm. Thank you so much!
