Bootloop. How can i enter Download Mode? - HTC U12+ Questions & Answers

Hello friends.
my U12+ was on 1.15.401.4 and was rooted with magisk. Today i wanted update magisk and the phone stuck into bootloop. But i was able with Power Button and then Volume Button to boot into Download Mode.. So i decided to update firmware. I downloaded the 1.14.401.4 RUU (cause i want to can OTA) and decryped it. installed boot and system image. Now Iam stucking into a bootloop!
Finally i had 0% Energy. So i Could Boot into downloadMode..
But after Flashing stock boot and system...bootloop...

Writing this also for other people looping:
1) In the unlocked bootlader warning screen: Press the power button once to PAUSE boot
2) Wait ca. 20sec and the phone will shut down
3) Press and hold the power button until you feel a vibration (not the initial one but after around 3-5sec)
4) Immediately let go and press and hold the volume UP button to reach bootloader

Okay so after doing a couple days research and listening to you guys, I found out when I rooted I didn't flash a recovery... So yeah I installed CWM recovery and then wiped cashe partision and it worked. When I wiped it, it came up saying to "fix root" as I may have lost in then I clicked yes then booted straight away. That's it fixed now.
Thank you for your help everyone!

When the phone is rebooting, press and hold power down, you'll then get into Fastboot. From there, go to Recovery using the volume down key and when selected, press the volume up to select. If it tries to install the update again, don't let it reboot into the ROM - when the recovery restarts itself, make sure you hold volume down again.

It doesn't work it just keeps rebooting and coming up with the "bootloader unlocked" screen after itself
1. With the phone powered off, press the VOL UP + VOL DOWN KEY together + POWER KEY .
2. The device will display different BOOT OPTIONS
3. Use the VOL DOWN Key to SCROLL to Recovery and VOL UP Key to SELECT
Tip: If the device reboots, you may have waited to long to make a selection, you will need to begin the process again.
4. The device will display the Motorola logo and then the Android in distress ( logo with Exclamation mark)
5. Press and hold the VOL DOWN key, then tap and release the VOL UP key.
Tip: You can try this step, holding the phone in landscape. If you are stuck on step 5, try a force reboot by pressing the power Key and Vol Down key, and start the process again.
6. The device will display additional menu options (Text will appear in BLUE)
7. Use the VOL DOWN Key to scroll to wipe cache partition and the POWER Key to SELECT this option.
8. The device will then perform the partition wipe
9. Once the Formatting is complete, press the POWER key to confirm a REBOOT
11. The device will reboot and start the normal power up sequence .
worked for me.....

Still none the wiser how to update to 4.4.4 though! I mean surely with a rooted phone there is an app to do it these days???
u can try this
if you have unlock bootloader and can go to fastboot mode,.try to flash your moto g using your 4.4.2 stock rom by manually (you can search how to do it),.flash partition gpt and motoboot (ignore the error),reboot bootloader and finished the rest command..flash phil touch recovery and reboot ro recovery,go to install zip,choose install zip from sideload then send your phone update using sideload command.
that"s solved my problems when i'm getting stuck on blank screen after unlock bootloader warning or only booting to recovery,i'm on 4.4.2 when get that error.
but now in my case,i should go to fastboot mode and choose normal powerup to make my phone booting normally,.because if i'm power on using power button,moto g booting to recovery,not a big deal for me as long as my phone back to the track hehehe
my moto g is o2 germany,but i'm flashing with 4.4.2 germany retail and 4.4.4 update for germany retail.

that's mean you can't access your stock recovery...try to flash your stock rom moto g 4.4.2 then install philz,use sideload to install the update file.

[Tutorial] Get rid of bootloader exception error

Hello everyone. This might be tutorial of how to get to download mode, when you flashed something the wrong way and have Bootloader exception error.
Don't forget to stay calm!​So, what you need to do?
1. Power on your phone (you will be stucked in bootloader exception screen)
2. Hold volume up + menu + power
a. If you have custom recovery (TWRP/CWM/idk...)
I. Find boot into download mode and done
b. If you don't have custom recovery (navigate via volume up, volume down, power buttons)
I. Find factory reset and wipe cache
II. Find reboot
3. Phone will be again stucked in bootloader exception
4. Normally, everyone will start to press volume down + home + power, but this will just loop the boortloader exception BUT, if you hold buttons long inought for the device to "reboot" 2 times, you should be brought into download mode.
5. If it does not work, just try again, again and again. You must be brought at least once into the download mode .
Hope this "guid/tutorial" will help you somehow.

Reboot to recovery not working

After shutting down when I press & hold power & volume up keys the phone keeps restarting at android one logo. If I release power key after screen on the phone just restarts in recovery. This method is posted on nokia official site. Is there any other method to reboot to recovery?
Note: My phone is stock with stock recovery.

Trying to flash TWRP to install lineageOS, but it boots in the stock recovery.

nvm

You need to restart the device in TWRP right after the flash with Odin or the default recovery will be reinstalled. To do this just uncheck Auto Reboot in Odin and right after the PASS message appears in Odin and following the instructions on the site: https://www.**********.com/root-samsung-galaxy-s6-s6-edge-on-android-7-0-nougat/ : "Press and hold Volume Down + Home + Power key on your device and as soon as the screen goes black, move your finger ad switch from the Volume Down to the Volume Up key immediately while keeping the Power + Home Key pressed. So the combination as soon as the screen goes back should be Power + Home + Volume Up. Your device should boot into TWRP recovery."
I did this by following this instructions to install TWRP on my S6 G920i and it worked.
Forgot to mention that you need to also install Magisk before restarting on the factory ROM or the device will go into bootloop. This is not necessary if you are installing LineageOS.
