Hey guys
I have a problem with bricked one x. I get it from my family. It has unlock bootloader and installed cwm. I tried to do something with that but it's first htc in my hand and i'm green. When i turn on phone it shows htc logo and than boot into recovery it doesn't shows me white screen with fastboot option etc , automatically run cwm. I wanted to flash kernel but I can't turn on fastboot mode or I don't know how. Please help my what should I do wake the phone up.
To Enter Fastboot mode
1. Switch off phone completely
2. Press and hold volume down and power
Phone should open in fastboot mode
Use vol up/vol down to make menu selection
Use power button to execute selection
Thanks

I can't turn off phone , only possible when my battery goes down. I solved that problem. I flash kernel with recovery (twrp) then by adb push moved rom on phone memory flashed rom and kernel and it works. Please close thread.
My ADB is On in settings and I can use ADB normal. But when my Phone is off I can't turn it on anymore the only way would be with ADB command: ADB reboot devices!
Power button + Volume UP/DOWN isn't working anymore...
The thing is, when connecting my Phone to my PC after it gets off it will show the charging animation. And when my phone reached 100% it stays in the animation and doesn't boot up. ADB isnt working in that state.
How can I boot my phone?? Pls I hope someone can help me PLS PLS
You must try conclude pins on motherboard for button volume up when you connecting USB cable, after that fastboot was started and you can type fastboot reboot command on pc.

If you have power and volume-down buttons functioning, boot the phone with the power button and when the bootloader unlocked warning comes up, press the volume-down button and you will get the options for restart, fastboot, recovery etc. Simply choose what you want with the volume-down button and confirm with the power button.

yes got that problem is i need volume up button to work so i can put in adb mode so i can flash stock rom,i decrypted my devices then installed the oneos rom and thats when i lost access to recovery and goot into bootloop?
So I wanted to root my device, and i did the steps till i flashed twrp(unofficial one for a50), i was at this point: To get out of Download mode and Enter TWRP Recovery mode: Press and hold Volume Down + Power key, when screen blanks release Volume down only and quickly press Volume Up key. As the screen blanked out i also accidentaly let go of the power button... bootloop since... I can't do anything, can't use recovery, can't use download mode, cant connect to it with my pc using a cable. so either i wait till the battery dies or i find another solution...
1. Unplug USB cable from phone.
2. Hold down power button till it shuts off
3. When it's off, hold vol up + vol down & Press power
4. It should boot to download mode.
5. Load stock rom for your model (Check the variant to make sure)
6. All is back to normal again.

I waited till phone died, then realised i could get it into download mode. busy downloading stock rom now. thanks anyway though, confirms my solution!
I have TWRP installed, and have managed to run it a few times. Now I cannot start TWRP at all.
From off, if I switch on, the following happens:
1) Screen with Samsung Galaxy A70 - Secured by Knox
2) 0.5 seconds later another screen, "this phone's bootloader is unlocked and it software integrity. .." and "press power key to continue..."
3) 5 seconds later, same screen as (1)
4) 3 seconds later, red letters "this phone is not running Samsung's official software"
5) 3 seconds later blank screen with "samsung" and then booting to android.
In my experience I have to flash twrp every time I want to use it( I don't know the reason but I couldn't fix it ) , for booting twrp on the other hand I turn off the phone first, then I press power button+volume down until the "this phones bootloader..." screen appears, here is the tricky part, you have to quickly let go of these two buttons, press power button, let go of the power button (after the warning disappeared) and then press volume down button (and hold it) until twrp logo appears, this happens really fast so you may need to do it a few times to get used to it.

Yes, same here, the only time I have managed to run TWRP on this phone, is right after a flash.

Do you mean volume down?

Power off the device, plug into a pc, wait for it to start charge, hold vol up and power till it turns on. Wala boots to twrp. If you have magisk installed,you can use the reboot option within magisk.

Samsung changed how to enter recovery on Android 11. Power off device, plug into pc, wait for it to charge, then hold vol up and power till it turns on. Alternatively, if you have magisk installed, use the reboot options within magisk.
I did that. Thanks!
But it has gone to:
Android Recovery
Samsung /a70qxx/a70q
11/RP1A.200720.012./A705FNXXUB5DVB3
user/release-keys
Use volume up/down and power.
Reboot system now
Reboot to bootloader
Apply update from ADB
Apply update from SD card
Wipe date/factory reset
...
...
...
Where is TWRP? It seems it's gone.

That's because you're not installing it properly go back to my guide and follow it exactly and stop listening to these other people. I've been modding this device since it first came out with Android 9, I know every inch of this device. You're getting confused by what other people are telling you

5- Press and hold vol down and power till the screen turns blank then immediately press and hold vol up. The device will reboot then land you in the twrp splash screen

It fails here, on this step. After successful flash of recovery.tar, power + vol down to reboot, cable still connected, nothing you can do now can bring TWRP up. The phone boots into Android.
EDIT: I think I have now got it. I will update in a few mins.

After successful flash of recovery.tar, power and vol down to reboot, as soon as the phone screen goes blank, immediately release all keys and press and hold vol up. Must be as soon as screen goes blank. The device will then reboot twice and land you in twrp splash screen. You must hit vol down and power after successful flash then when screen blanks, vol up. If you miss this step, twrp will not hold and revert back to stock recovery.
Here is the notes I made today:
****************************************************************
INSTALL + START TWRP
phone is off
press up + dn
insert cable
go into download (press up)
ODIN 3.14 + AP:tar(vbmeta.img+twrp.img), auto reboot off, press upload
when it succeeds, press dn + pwr until it reboots
then quickly up + pwr until it starts (no need to hold down)
this starts in TWRP
from powered off
press pwr button
goes into twrp or android(system) -- depending on what was used last time
if we used reboot->system last time it will now **Always** go into system!
to go back into twrp:
switch off
power cable until charge
pwr + up until it starts
****************************************************************
The above means that you CANNOT go back to TWRP unless you have a cable and a PC near by.
