Can not flash anything, please help! - Android Q&A, Help & Troubleshooting

Well the power on/off button on my g300 doesnt work anymore because i broke it.
and i can not select anything from the recovery menu and i cant even boot to recovery but i can boot to recovery from ADB
i tried flash with fastboot the cwm touch zip and img but none work because it always says waiting for device
also when i write adb devices the device is recognized but when i write fastboot devices it doesnt say anything
and when i turn the phone on, i had b2g but i forgot the security code, i managed to delete the settings with adb and it was back on default and b2g booted normally, now it doesnt boot anymore and i only see the red huawei logo is it possible that i have softbricked my phone any way to fix this?

hi. I have prime and it is stuck into twrp screen with just teamwin screen keep on flashing. nothing happens and it doesn't boot into recovery(twrp) also. tried to boot into bootloader by holding power button and volume down but nothing happens. then tried adb. used abd reboot bootloader and also adb fastboot recovery. but nothing happens, only shown "waiting for any device". thought adb not working but when I type adb devices.....it shows device serial number and recovery written next to it.

How to change build. prop file in the devices without fastboot option??

Hii I have a chinese yxtel g905 android mobile. I have rooted it and changed the build. prop file. After rebooting it the phone is not booting. It is just powering on and immediately after the boot animation is completed it is turning off and it also don't have fastboot mood or recovery option.I have tried this by long pressing all the possible combinations of buttons. So someone tell me friends is there any solution for such a problem?? Like feeding new build. prop file into the device or anything like that.
Some devices show no signs of activity in fastboot mode.
It might look like that the phone is switched off but it would actually be in fastboot mode.
To check, try power + volume up/volume down/both then connect the phone to the PC (with all the necessary tools and drivers) and type
Code:
fastboot devices
Into the command prompt.
It will show a list of all devices that are in fastboot mode and connected to the PC.
If you are able to confirm that the phone is now in fastboot, you can proceed to flash the stock ROM (given that you already have it) to your device.

boot loop with broken volumes buttons

Hi all, I wonder if anybody can help with this.
my volume buttons are not working (hardware issue) and I was trying to install TWRP and a custom rom but, after installing TWRP the phone now always boots in recovery mode (at least this is what adb tells me) but TWRP does not really start, I keep seeing only "honor, powered by android" black screen.
adb is working but not fastboot. I tried to reboot to bootloader but it always go to recovery instead. I have no su, and I am stuck just with adb in recovery.
any idea?
If you have full adb access maybe you can restore your backup directly from it
Thanks Rayan
how? what do you mean by "full adb access"?
I tried to run adb sideload but it does not work (it says "closed" shortly after without doing anything)
I don't really understand what the issue is, do you have access to TWRP menu or not at all? And when you say that you can use adb, is the device recognized when you type adb devices ? And what happens when you try to boot in bootloader and use fastboot? Can you try to the command "adb reboot bootloader"?

Click to expand...
Click to collapse
Thanks Rayan, I finally solved replacing the volume buttons (found cheap ones). However adb was working but no matter which command I was sending (adb reboot bootloader) the phone was always rebooting in recovery mode but TWRP was not starting properly (could not see anything)
with volume buttons I managed to enter into bootloader, reflash TWRP and do everything I needed
Thanks

[Wileyfox Spark+] help decrypt and root device

hello
Yesterday my WileyFox Spark+ came in, which is still equipped with COS13.0.1, based on Android 6.0.1 and encrypted.
For disable encryption,i had followed the following process:
- factory reset whith sitting and recovery mode,
but without result because turned out the phone was encrypted with a startup pattern already from the box.
As I was unable to root my device, I have used adb and fastboot to install twrp with the commands :
adb reboot-recovery
fastboot flash recovery twrp.img
fastboot reboot
Then I press to volume down button to display the recovery menu but, instead of displaying the menu, the device boot again and again until I'm tired and I release the button. Then the phone boot normaly on Android...
Any idea how i should progress further?
Thanks for the help.
