[Q][Help] Adb unauthorized, volum down, cant boot into recovery - HTC Sensation

Hi guys,
So after flashing sultans new 3.4 kernel rom, i got myself into a random boot loop. The only problem is that i cannot get into the recovery to fix it, since my VOLUME DOWN button isnt working, and i cant go to adb because it says unauthorized. Is there any way to solve this problem ? Please, i Really need this phone to work
Thanks

Hi, No I cant boot into the boot loader using VOLUME DOWN + POWER BUTTON, and I am S-OFF. I was trying to use adb since my volume down button doesnt work, so I can boot into recovery. And Im stuck in a bootloop.

it doesnt work, it says the devise is unauthorized. Andriod 4.4.2 has a safety feature where you have to first confirm whether you want to use adb to use adb, and i cannot do that because im stuck in a bootloop.
so when i type any adb command it says devise unauthorized

im also waiting this solution.
stuck in logo, and can't confirm popup cornfirmation

It will only work on UNLOCKED devices
It requires access to Fastboot to prepare device first time
It won’t work on fully bricked devices (See 2.)
You need to keep files safe!
If you upgraded to Offiical JB it *won’t* work!
i'm not have fastboot and i'm on Official JB
i have try to enter on APX mode but i can't
did you try to install the asus pc sync (it shoul install the driver for use adb & fastboot) and after boot into recovery
from prompt you should be able to use adb
write adb devices
and if you can see the code of the devices may you can still have a possibility to flash troght adb
ok man i understand the problem today
i have flashed the last TeamWin Recovery but not compatible with 4.2.1 but 4.1 stock rom and now all partition can't be mounted in recovery, i have found adb in broken recovery and push recovery img for flash with dd command and all done in shell but nothing flashed !! then "adb reboot bootloader" for try to reflash with fastboot, same story all done in shell but nothing flashed !! ok no problem i try to boot android in boot menu and damn partition is ok and android booting !!!!!!! :laugh:
ok remain 2 way. use dd in terminal emulator but can't without root permission and use nvflash but it's not work with JB confirm ?
waiting for a tool using an exploit for root from internal android and try dd or next update for nvflash.
any idea ? and sorry for my very bad english

Same issue here. I'm able to use Adb reboot bootloader command. And get to boot loader. From there I can cold boot Linux. So I have my i

and what do you think about ?
if you can boot the system may you can verify again the bootloader whit asus tool from the website maybe for any unsense reason it's locked....
ops wrong tread
Ok, I just tried some stuff and:
1. I can also access fastboot and OS.
2. Trying to flash modified TWRP with fastboot freezes bootloader.
3. In-system can't open .RAR files.
4. After manually transfering unpacked V8 unlocker from PC it says there's an "unknown problem" when trying to install unlocker. It supposedly upgraded from V7 to V8 app without problem.
In bootloader it says at the top of the screen that "Key driver not found... Booting OS". After that it lists bootloader info ( v. 1.00 e ).
Looks like recovery's bricked with some further issues in the OS itself.
EDIT:
Bricked the OS. Tried reflashing stock system and now bootloader freezes when trying to boot OS. My guess would be that fastboot can still erase stuff but most likely can't write ( at least not properly ). Google/Asus probably know of a way to restore our tablets but Asus clearly prefers to replace motherboards.
I have to think whether it's worth it for me to replace the MB but most likely will just sell the thing for parts.
whan you try to re-flash the system somthing goes in the wrong way? do you still have fastbooy access? was the usb debug on?
sorry but which rar you can't open?

[Q] Bootloop and Broken Power Button

My phone is bootlooping and the power button has been broken for a while. I've tried various things posted in other threads, just wondering if anyone has any solutions or ideas.
I can't seem to get it to connect with usb in the bootloader but it does connect while bootlooping. Can I fix it while connected in the bootloop?
edit: Actually, now that I've researched more, I'm pretty sure the problem is that my bootloader is frozen. That's why neither my functioning volume keys or adb works in the bootloader.

I can't seem to get anything in the Nexus Root Toolkit to work while it's bootlooping or while it's in the bootloader even though it comes up in my device manager as Google Nexus S ADB Interface while in the bootloop.
Is there a way to fix it in the command line, or is that just the same thing as using the root toolkit?

Can you get into recovery?
No I can't get into recovery because my volume buttons won't let me navigate the bootloader options. They aren't broken, they just don't work in the bootloader for some reason. My power button is physically broken though so I don't know how to get to recovery or if I can even use recovery without the power button...
I think fastboot will work without a power button?
This command...
adb reboot bootloader

1) Download latest CWM Touch.
2) Follow steps from here to install CWM.
3) Boot in recovery using the command in the above link.
4) Download a flashable touch recovery from here.
5) Mount USB in the recovery and copy this zip and flash it. This will make your custom recovery permanent. Reboot to recovery again just to verify.
Now, you have a touch recovery accessible through fastboot and can install custom ROMs

Thanks for the step by step! The problem is I still can't get the adb working in the bootloader to install CWM Touch. When I type adb reboot bootloader it says "no device connected." If I type the same command while the phone is bootlooping it says "device unauthorized."

You can't use adb in fastboot. There are fastboot commands for that.
Step 2 has fastboot commands to install custom recovery.

You can wait till the battery drain and then connect your phone to PC holding the volume button to enter bootloader and then using Nexus Root Toolkit flash your stock rom.

[Q] Where has recovery gone?

no access to recovery
I've got big problem. My One Mini is fine until I try to go into recovery. It refuses to go there.
I get fastboot and bootloader menus fine. It enters bootloader, but if I try to go into recovery, it just goes back to the main bootloader menu.
The problem started when I flashed CWMRecovery. Fastboot and adb recognise my phone, and accept commands, but when I try to fastboot flash recovery in it sends an error message. File not found.
I tried " fastboot boot recovery.img" but that just froze the machine .
When I try to get into recovery from rom manager or ROM toolbox pro, it takes me to the fastboot menu, not into recovery, and we're back to square one, as above.
Running android 4.3 Sense 5.5 software 2.12.401.1 Supercid 11111111
rooted and unlocked
To get the phone to work again, I have to hold power down for about 10 secs direct from fastboot/bootloader...may have to do this several times before it boots into Android.
If I turn power off from bootloader, it returns to bootloader when I power up again.
If I don't turn the phone off, once in main application, it's all OK.
Ho hum.
As I say , it works like a dream until I want to go into recovery.
Any ideas, please?
Thanks

The correct command to flash the recovery is
Code:
fastboot flash recovery your_recovery_image.img
see also: wiki.cyanogenmod.org/w/Doc:_fastboot_intro
Booting into recovery should be possible with
Code:
adb reboot recovery
I didnt tried CWM on the Mini, but used it on my old Marvel. I'm satisfied with TWRP for the Mini.
greetings
Yes, thanks. I know the commands should work...but that's the trouble..they don't!
I can get into the recovery menu...HBOOT /FASTBOOT / RECOVERY and so on, but selecting "RECOVERY" simply sends me back to HBOOT menu.
I can't flash anything under FASTBOOT, either. I've been doing this sort of thing for several years without trouble....until now!
So come on chaps..thinking caps on , please.

The RUU wouldn't run: it reported an unknown error, but having done so, it must have done something, as when I rebooted, I had access to recovery once again...briefly! Then it went again.
Anyway, I re locked / unlocked , locked a few times, and hey presto, it's sprung back into life!

Reflash bootloader?!?

Hello, I'm using HUAWEI Y300-0100, and I installed CM11 on it. The thing is I cant enter bootloader at all and I get often random reboots. Tried to enter bootloader via adb command, via apps that give that option, and button combination, still nothing. Is there a way to flash bootloader only, via recovery or adb perhaps? Thank you anyway!

Hi, when you enter command does it get stuck at the Huawei splash. If so this is the boot loader. I know it is strange but the boot loaders on these devices are very minimalistic and rely on ADB/Fastboot commands from the PC
No, it just does normal reboot. I think it is somehow connected with random phone rebooting.

Need Help. Nexus 5 says google when trying to turn on

I was trying to get the latest twrp '2.8.7.2'. I downloaded it and flashed the img to recovery and nothing seemed to happen so I tried flashing it to boot then I tried to reboot the system. Now when I try to turn it on I get stuck on the Google like it is turning but it just gets stuck. I tried Charging it now when I charge it I get stuck on the battery logo. When I try booting it Booting it into recovery(twrp) I get a black screen. I can tell the Screen is on because of the dim glow it gives off but it is not doing anything. Note: I am some what of a noob when it comes to this stuff, My nexus 5 was running Marshmallow, and I was running the Xtra smooth rom (it is very close to stock). Plz help. I have also just found out that the reason im getting the bootloop is I flashed the wrong version of TWRP need a fix PLZ HELP.

All you have to do is boot into your bootloader (Power + Volume Up + Volume Down at the same time) and flash the stock recovery.
fastboot flash recovery recovery.img
Chances are you flashed an incorrect version of TWRP meant for another phone hence the boot loop.

Can you please explain to me exactly what to do. thank you. also my bootloader is unlocked. I also can get to fastboot so what is the diffrence between bootloader and fastboot.
Hold down the volume +, volume -, and power button. You'll be taken to a screen with the word START at the top. Now, connect the phone to your Windows computer using the USB cable, open a command prompt and type "fastboot flash recovery nameof twrpfile.img", press the enter key, use the volume button to select recovery, use the power button to enter recovery, press the power button, press volume + button, and you should enter TWRP.
Thank you but I do not own a windows computer
Then look up the respective commands. You flashed twrp over your kernel, you need to flash a proper boot.img (kernel) if you want the phone to boot. Fastboot is ran through bootloader. Flash the proper kernel in bootloader using fastboot.

It might not have been working because I did not enable USB Debuging. :crying:
USB debugging is required for adb commands. With fastboot mode, debugging isn't necessary.
