How To Enter Recovery if phone wont access Hboot or Recovery - HTC Sensation

Ok So my phone wouldnt access hboot and wouldnt turn on and i was basically F'ed and phone repair shops said my phone is useless and that i should throw it away since adb commands wont work but i found a way on how to do, it might take a couple tries but basically i figured out that your pc discovers your phone for like a second and then waits for it to turn on so remove all your sd cards sim cards etc and remove the back cover then remove battery and put it back in then plug in your usb cable to both the computer and the phone then open adb and get the command ready for " adb reboot recovery" and wait there and as soon as you hit the power button on your phone hit enter on the command and it should access the recovery and you can do this to enter the hboot and etc, share plz ;D

Help backing up to SDCard please

I've been trying to get this to work. I got the intructions from this site... http://www.geekzone.co.nz/inane/1119
I put the phone into bootloader mode, and connect to my XP laptop via USB. I run MTTY and click on the USB button. I hit enter to get the USB> prompt.
I type "d2s 74100000 00a00000" without the quotes and hit enter
My mtty screen looks just like the one in the instructions. I took the sdcard out of the phone and set it aside. To test whether it will restore from the SDCard or not, I burned a new ROM with 1 OEM removed to my phone and performed a hard reset. I then put the SDCard with the rom dump on it back in the phone, and put the phone into bootloader mode. I get the screen that says "PRESS POWER TO FLASH". I press power, it says its flashing. It finishes and says it completed succussfully. However, after a hard reset, the ROM that I backed up to the SDCard is not the ROM that is running on the phone, it has the one that I burned to the phone with the 1 OEM Removed.
Has anybody ever tried this and got it to work successfully?

[fix] htc one s stuck in bootloop, volume down button not working [root][fix]

So here was my situation:
I was flashed the wrong piece of software (stupid me) and I was stuck in a boot loop. Unfortunately the volume down button on my HTC one S was not working so a simple boot into bootloader mode did not work!
Furthermore, I couldn't even get the phone OFF! Pressing the power button for minutes on end still ended up in the HTC constantly rebooting itself. (Worst thing ever!).
FIX:
Step 1: Power Off device
Although this may sound very easy to do, I could not get the device powered off via the power button(10-20 secs) so I had too do it the hard way.
Luckily, the One S being a sealed phone isn't actually hard to take apart. Its actually rather simple!
I used a video on youtube to disassemble then took out the battery for about 30 minutes. (Search "HTC ONE S fix" on Youtube and you'll find it. Sorry i can't post any links im a junior member!)
Step 2: Plug the USB cable into your PC
Put the battery in ( if you used the physical battery pull out of course)
With the device completely off plug the cable into the PC and run the command
Code:
adb devices
By doing this my device actually went straight to the recovery screen and the device was recognized on the computer.
Now the recovery screen i got wasnt very helpful as it continuously rebooted and eventually booted back to the white HTC screen.
HOWEVER, the fact that I could use ADB commands gave me hope.
Step 3: Reboot into bootloader using adb command
Code:
adb reboot bootloader
This is where I really saved myself i ran this command and got to the bootloader screen and I was able to actually work with that!
Step 4: Flash/ Restore Backup to your device and get it up and running!
Now there are a couple of ways you can choose to do this depending on your specific situation and resources available:
A) When in bootloader mode you can access the fastboot commands which will allow you to run any flashing commands that you need to rewrite whatever is corrupted (e.g boot.img)
B) If you have a working recovery simply select recovery and boot into recovery and flash either your nandroid backup or a new ROM as a whole
C) This is what i did, I ran a stock RUU which deteccted my phone and in 10 minutes my phone was up and running!!
Now I know this is a rather rare case, but I actually thought my phone was gone and the fact that I got it working really motivated me to put this out there so someone like me may be able to get their phone up and running again!
Forgive me this is probably my first real thread, Hopefully I continue to post how I fix some of the rarest occurrences I always seem to get myself into.
NO MORE BOOTLOOPS! Who says we need volume down buttons? LOL

Semi bricked device following a CM12 flash

I flashed CM12 a few days ago on my rooted HTC sensation, with unlocked bootloader, S-OFF etc.
The install has not gone too well, and most of the programs started force closing, to the point where all the android can do is shut down, restart, or go into aircraft mode by holding the power button.
I can not send the phone an adb reboot-bootloader option, because the phone wont prompt me to authorize my PC for remote commands, and I cant get into the bootloader of the phone by powering on with volume down + power, because the volume down button is faulty.
Is there anything else I can do to recover the device and re flash, such as placing a file or script on the SD card for when it boots??
Thanks for any suggestions/help.

Have you tried turning the phone off, plugging it into the computer, turning the phone on, and keep on sending the adb reboot-bootloader command as the phone is booting up? I've heard that this works as the phone will eventually get it at one point while its booting up.

[Resolved] [HELP] Phone not reacting, power button broken

Hi,
I have a problem with my Motorola Moto G4. I bought it 2 months ago and unfortunately the power button broke and I am therefore not able to turn my phone on/off. That is in general not a problem since the device is still under warranty and I will get the phone repaired. The problem is that I want to backup my data, which I am not able to, before getting the device repaired since the workshop will reset the phone.
I am still able to unlock the phone but no apps or windows can be opened (taping on an app icon does not do anything). Dragging down the notification bar is possible and if connected via USB I can still see the status, unfortunately I am not able to change the setting from charging only to data connection. Since the power button is broken I am not able to reboot the device. I tried to use the adb tools to reboot but the device is not authorized and I would need to change that on the phone which I am not able to. Is there any way to reboot the phone or to access the data.
Any help would be really appreciated.
you might be able to try the commands for adb reboot recovery as the phone is booting up - iv never tried it but adb should be working after the moto splash screen (during the boot animation)
Im not sure if it needs authorisation during that stage but if you cant get into recovery and you cant change the usb connection/authorise adb then I cant see any other way to get the data off

In that case I don't see how you can access anything if you have no adb & you can't select anything on the phone

If I would drain the battery to "shut down" the phone, would there be a way to turn the phone on without the power button?

with older samsung devices you could use a usb jig to get into download mode without the power button (its a usb cable with some pins crossed you can buy them for only £1 off amazon/ebay)
even if it did work you would still need the power button to select the option to restart phone so the answer is nothing that I can think of

I found some mechanisms to get the phone turned on and I will try them out. I guess I have nothing to lose.
The interesting thing is that my phone is still receiving messages and news (I see them in the notification bar), so things like that are still working but unfortunately new "widows" can't be opened.
Thank you for your help.
I was able to get the phone rebooted and after the restart everything works as it should.
This is what I did:
Drain the battery (using the flash light), once the battery is flat connect the phone to the PC
Press and hold the volume down button until the Fastboot menu appears
Download ADB tools (the minimal version with adb and fastboot is sufficient)
Install the Motorola driver on the PC (I was not aware that I need this, since connecting the phone without the driver being installed and running adb device results in the device being shown)
run fastboot reboot

Question Samsung A12 (SM-A125U) can't flash stock ROM or enter "Downloading mode"

Hi,
I am trying to flash the stock ROM to my phone (worth noting that this is an AT&T phone). For whatever reason I cannot access this "Downloading mode" by pressing the volume up and down buttons at the same time and then plugging in the power cable (the cable is plugged into my computer, not the power block, if that makes a difference); it just shows me the charging symbol and does nothing. I have read many places that in order to use Odin I have to get into this mode; so this isn't working, and I got as far as downloading Odin and putting the proper files in the designated fields.
When I try to access the phone in recovery via adb and fastboot, adb will show the device in the device list, but fastboot won't. Why?
I don't know why these phones don't allow for flashing the OS through the SD card, but that isn't an option either.
I can't do anything from here that I know of. What's my recourse?

I mentioned in the OP that I tried that. I still cannot get into the downloading mode. The guy at the cell phone repair shop claims to be able to reset the phone though. Does he have special info from Samsung?

Nope, it's just that your cable or something is probably broken, or something else is going on, try another cable, maybe?
Hey if u were able to boot into recovery did u try Reboot into bootloader option ?
