Need some advice....

I tried to root my phone and followed all steps until it asked to boot into the custom recovery and that only displayed a blackscreen and if I tap on the screen the phone vibrated. I cannot boot into bootloader as the phone just automatically tries to enter recovery with blackscreen.
Hold all buttons the phone boots normally and can use the phone as usual.
I've tried to use the adb and fastboot cmds to restore and factory reset but just reboots and tries to enter recovery with the blackscreen.
My device is htc_a51ul if that helps.
Thanks,
Phatzy

Tighten two volume buttons and the power button when you see a black screen and holding down the volume- and power button that would go to zagruzchik.Telefon must be connected to kompyuteru.Esli got to go to the boot loader, boot into download sistemu.Esli not work then you have forgiven stock rekaveri of loader. https://yadi.sk/d/nWnRAChBnEtxG

I think you have flashed a wrong recovery ,first thing to do now is flash stock recovery and whether if it is working fine if so then flash the proper version of twrp 2.8.7.0 is recommended and see if it works
I had the same issue when I first flashed twrp on lollipop but then I did the above and now everything is fine.

while its on the blackscreen only adb commands work. If i try fastboot commands its just waiting for device and phone dont respond. I cannot get into bootloader at all with volume keys or with adb command.
Many thanks for suggestions.

Ok I have now managed to get bootloader back and I can now enter the stock recovery but when I enter recovery it has a red triangle. Is there anyway to remove this?
Thanks.

Tried flashing CM13, now can't enter normal boot

So I already had a rooted (and I'm pretty sure unlocked bootlader) version of the stock Asus and wanted to put CM13 nightly on there. Everything was going smooth until I got to the stage where I have to load into TWRP and I got the error screen with the little dead alien and the red symbol.
Now I can't enter normal boot, but entering recovery mode seems to work. I tried the option to side load a package from ADB on that screen but nothing worked (.zip files extracted, but I got an error on the phone).
As you can tell, I'm really new to this so any help would be greatly appreciated. I tried looking around, but it seems the more common issue is people not being able to enter recovery mode or something similar.
Thanks

Looks like your doing it wrong. Being rooted does not necessarily mean that your bootloader is unlocked.
By the looks of it your in recovery mode with the dead robot with the "error" message. That is normal. To reboot back into system you either have to press (I don't remember) power button and volume up or down button. Then you should see some options with reboot to system. Or if that does not work you can hold the power button till it turns off.
Then you get back into Android, download the official bootloader unlock tool from ASUS and install it on your device. NOTE: If you updated to MM then this will not work and this will void your warranty.
Run the tool and press unlock and it should reboot into fastboot where it should begin the unlocking process. I believe it should automatically reboot and you should see that the Asus logo is now black instead of white. If not, repeat the process.
You can now proceed to flash twrp recovery. Boot into fastboot/bootloader mode either with "adb reboot bootloader" or hold a specific set of buttons while off to go directly into fastboot.
On the computer, connect your device and type in "fastboot flash recovery (path to twrp IMG without brackets)"
When done you should be able to reboot into twrp recovery where you can flash the cm13 zip.
Hope this helped.

Stuck in recovery after ADB with broken power button

Its very complicated. My T705's power button was damaged by water. And i flashed Stock MM rom with odin. It was fine after flashing, the tablet boot into the os properly, work very well in the os.
But then i want to wipe the cache and data after that, so i was using the code"adb reboot to recovery" to get into recovery mode because my power button was broken. (I thought it can be using home button to select in recovery mode)
But the nightmare is i can't select anything in recovery mode which requiring a power button. So i can't wipe the cache, also can't select the option to reboot my tablet...... I've tried to hold both the volume down and home key to go to the download mode menu, and select restart by holding volume down, but it go to recovery again even after removing the battery, i think it's because the adb command.
And the strangest thing is i can't use my volume up button in download mode menu, so sadly i can't flash the rom again,:crying: but the volume up is working well in recovery and in the os......
Is there anyway to prevent the tablet to boot into the recovery again? I'm quite sure it's not the problem when flashing MM rom, the problem should be the adb command makes my tablet boot into recovery until i change the boot setting in recovery mode.

Holding vol down + home key can boot to the download mode menu.
But the device will automatically turn on after inserting the battery, no need to press any button, but the device only boot into recovery after i use the adb boot into recovery command.

If that's the case that means the power button is stuck on or you wouldn't be able to power on or boot to Download mode.
All you need to do is flash the stock firmware or twrp and it will reboot back to the OS.

Hopefully I've got your fix:
When you insert the battery your device boots up, if so, insert the battery and press the correct key combo while the splash screen from logo.bin is showing to boot into the download mode.
After that flash TWRP latest version with Odin. Then when your phone again boots to recovery, chose Reboot -> System to boot Android.
---
If the above isn't applicable and you can start Android somehow, I will download either FlashFire or MobileOdin to flash another recovery/ROM.

Phone not turning on anymore from TWRP install

I had a stable running device with Magisk and TWRP. Yesterday evening I successfully updated to the latest OxygenOS 5.0.3. The update as expected and as usual restored the stock recovery so this morning I downloaded the latest TWRP .img, went with the usual routine of enabling USB debugging, rebooted to fastboot and flashed the TWRP recovery.
The phone rebooted and I forgot to do the combo to immediately enter TWRP to patch the boot image and avoid the stock recovery being rewritten. So during the oneplus boot animation I forced a shutdown by holding the power button, re went to fastboot and re flashed TWRP, then I tried to reboot with the combo to enter recovery and here starts the issue.
The phone shutdown and never turned on. Also attaching it to the charger doesn't show the usual charging animation. I've read the Mega unbrick guide but holding the Volume Up doesn't show my device on the pc so I can't proceed with any of the suggested methods.

Try holding down the power button for >40 sec and if the phone powers on, reflash OS, TWRP and Magisk before booting again.
If not successful, hold down the power+vol up/down buttons for >40 sec and see if it powers on.
If all else fail, disable signature verification in your PC, install the OnePlus drivers and try to connect.

Hold volume down and connect to the pc download the unbrick tool and start it

Phone might be bricked. Need help to find a solution!

Hello everyone! Complete dumbass here!
I was following the guide to root my razer phone. I've had it for a couple months, and decided to root it. I followed the guide here https://forum.xda-developers.com/razer-phone/how-to/twrp-magisk-fullproof-guide-razers-wifi-t3756137
After a couple bumps in the road, such as fastboot commands not working, not being recognized, etc. I finally was able to unlock bootloader and install twrp. But it was #9 that got me stuck again.
"9.) Once in recovery, go to the install button, and select Install Zip, and select Magisk-v16.0.zip."
In recovery, adb devices and fastboot devices yielded no devices attached. Doing a search, I came across another forum post where it states the sdcard is encrypted and can't be accessed in twrp, and the fix is to do something like "Wipe>Wipe Data> Type Yes" and that should factory set the card. I did this and rebooted the device. I waited for a half hour for the animated PixelFloatingInACircle logo to be done with it's floating in a circle, but ended up going to bed and letting it die. Woke up this morning, plugged it in, got the razer logo splash screen with the orange text telling me of my impending doom, then went back to the animation. I let my dog out and came back and it was still on. I unplugged it and am letting it die again to see if there's another solution.
I'm wondering if anyone else came across this issue, and if so, how did they fix it? Any help would be appreciated.

Use the factory images in the developer portal. You have to manually install the fastboot driver or you won't see the phone in fastboot devices. After that you can flash_all.bat.
PS: if you just want root you can use magisk installer to patch the boot image (from the factory images) and then flash the patched_image.img. That's it, now you have root via magisk

The problem is when I try to enter download/recovery mode after charging the battery a little, it doesn't go to that menu. Instead, it skips right to the particle logo, and that's where it hangs.
The only guide I saw was the one I listed. Is there a guide for this magisk installer?(Ya know, in case I figure the first problem out, so I might try my hand at potentially creating another)

i think there is a way to hard reboot the phone, so you can do that and then hold the vol- key to start in bootloader mode when it reboots.
gonna check the correct buttons.
Edit: the button combination is power+vol+ for about 10-15 seconds, and the phone will reboot. You have to connect the phone via usb cable (before rebooting) to the computer (the only thing i'm not sure is if you have to have the fastboot drivers in the pc installed previously or if you can do it after entering fastboot) and just after the screen goes black while hard rebooting you have to release all the buttons and then press and hold the vol- button. The combination of vol- and the usb cable on boot seems to trigger fastboot mode.
I think the guide is in the guides forum, but the way it worked for me was without twrp:
- install magisk manager from this link -> https://github.com/topjohnwu/MagiskManager/releases/download/v5.7.0/MagiskManager-v5.7.0.apk
- push your boot.img (the easiest way is getting it from the factory image corresponding to the firmware you are using) to the sdcard
- open magisk manager -> install -> patch image only -> boot.img
- this will generate a patched_boot.img in /sdcard/MagiskManager
- copy that file to your pc
- go to fastboot and flash that patched image: fastboot flash boot patched_boot.img
- enjoy root, and you can use magisk hide for apps that don't like root

Read the edit, I found that the trigger is having the usb cable connected to the pc. Try that, or you can also try to adb while the device is booting (particles logo). Sometimes adb is responsive even when booting. There you can try to adb reboot bootloader

Progress! Got it into download mode. I have the boot.img I got from razer, should I push that and see if it boots normally?

As you already wiped the data partition, you should use the flash_all script. But yes, you can try flashing each partition

I moved the flash_all script into the tools folder and after a little while, the phone booted up into setup! After a couple taps, I've realized the wifi isn't working, which I know is a known issue. I'm gonna let it sit for the night and finish it in the morning!
EDIT : Soooo, I know I said I was going to bed, but I decided to fix the wifi issue, which in turn, also rooted my phone. I've downloaded the root checker, and it confirms it! Thanks so much Waiflih! You rock!

Hi guys, it seems I'm having the same problem and basically after unlocking my bootloader and flashing twrp to both of my slots I'm stuck on "Your device has been unlocked and can't be trusted" booting up infinitely.
The USB plug in and holding the volume - button doesn't bring up "download mode" and no matter what buttons I try and press on my phone my computer doesn't recognize ANYTHING connected to it anymore.
Bloodeagle, how did you manage to get "download mode" back onto your phone? it seems like mine refuses to do anything like download mode.

Have you tried holding few combinations of different butt9ns for a minute or two to see if that results in you getting in downl9ad mode?
