Hi,
I flashed TWRP and CM 10.1 but then I got problems with the phone not charging (still having that issue but will post it in another thread). Anyhow I decided to reflash the the stock rom and during the flash the phone randomly restarted. Luckily for me I was able to boot up and everything is working fine. the only problem is i can now longer access my system recovery (power and vol down) or fastboot mode (power and vol up). When trying power and vol down the phone starts up as normal. when trying power and vol up the phone vibrates, the bottom 3 keys light up and then nothing. I have to then hold down the power button to turn the phone off and back on. I hope someone can help me troubleshoot this as I have no idea what to do.
Many Thanks!

Recovery is accessed by volume up, volume down, and power held down simultaneously for approximately 10 seconds or until you see recovery. Not sure about fastboot. Have you tried to see if your in fastboot by using adb and checking for fastboot devices. You may be getting fastboot mode. I forget if it actually said anything on the screen. Good luck!

Try search for a app called Quick Boot on play market.
Hi
Nexus 4 wont boot to bootloader/recovery after bootloop even with h/w button combos. Heres what happened:
It was a rooted and unlocked phone running 4.4.4. It couldnt update via OTA. So i thought of unrooting + flashing the stock but with the latest lmy48m using WUG's Nexus Root toolkit. After installation it went on to boot (4 dots flying) . It went on for 10 minutes and thought that it went to bootloop again( ive tried similar things on it before and waited for a night etc. ) . So i tried the hardware button combination (power off then Vol - & Power button combo for bootloader mode and Vol + & - & Power) to go to bootloader/recovery mode but all it does is get to the Google boot screen and go to the bootloop mode. . Then i left it to boot again overnight and its still the same.. I tried a lot of times to get to the bootloader mode and recovery mode with no hope. My pc doesnt recognise in fastboot or adb since then.. Just as MTP device in boot or android device when charging. Searched through a lot of forums but nothing worked.. Tried to remove the back cover and then pressing the button combos - still the same.. What to do next?
Please Help!
Thanks

there is an option of soft-brick/boot loop in toolkit. have you tried it ?
hi.. Yeah.. But the device wasnt being detected at all.. also it required the phone to boot into the bootlader/recovery which i am not able to
Did you happen to save the NRT Log from your attempted flash? Might be helpful to see.
Hi,
I'm having issue with a GT-I9505 S4 phone after droped it in the water, key combinaison to turn the phone up are altered, if i only push "power" button, the phone boot in recovery mode, if i push "volume down + home + power" the phone boot android in normal mode.
I've tryed to re-install samsung stock rom, the problem persist, i've tryed to install cyanogenmod 12 and problem still here too.
It's seem the water have corrupted a firmware (maybe qualcomm's firmware?) so i don't find which one !
When powering the phone with "volume down + home + power", all work just fine !
I've checked if some buttons are stuck, so it's seem they work fine too.
Partition mapping seems good, using adb to restart the phone in recovery, download or normal mode work fine, so if i try to reboot from android's menu, it boot in recovery mode.
Does anyone have some help or infos to help me to solve this problem?
Is it possible to "re-map" the key combinaison for turning up the phone?
Thank in advance

Hello,
I installed LienageOS but could not get root working, so I tried flashing SuperSU from recovery. After this, the phone is stuck in the LienageOS boot logo.
I cannot go into recovery as the volume-up key is not working. I already changed the buttons flex cable, but seems like a board problem as it still doesn't not work. I also tried disconnecting the battery and waiting a few minutes, then reconnecting the battery, it works for other phones, but not ZF5.
Is there a way to force the phone to boot into recovery, without using the volume-up key?
Could you go to fastboot ?

No, as the volume keys don't work. if there's another method to get into fastboot I'll try it.
I was tried it
Hello i am trying to root my 1year old heavy used phone . I am Stuck at the very first step.
Also it should be mentioned that it got a little bit wet by rain someday and then the volume down button was stuck (not mechanicly) it forced the volume setting to zero and had no sound.
I soft reset it . Than no change. had a hard time getting into recovery but i finally got there somehow i dont remember how.
Then hard reset it.No change....
After one day the volume key fixed itself and everything is working fine.
now after one month i was curious if i could root it. But i am not able to get into bootloader state.
I tried everything.
Debug options and oem bootloader unlock switch enabled, usb debugging enabled.
Usb adb says no permission (serial n visible)
Entering Recovery mode at power off state by
Pressing vol up and power button gets normal boot everytime but much faster logo visible at about 3sec.
pressing power + vol down = it takes 25sec
Booting normal .. and the same happens when pressing both vol keys.
I am releasing the keys at zte logo visible everytime
Something was strange : one time when i was trying something it bootlooped 3 times and then it was safe mode.
could there something in the volume button be broken? but the button work fine. I dont know.
Thanks for reading
update:
ok the permissions was a linux issue(start the adb-daemon with su), i can use adb now on this phone,
i can boot it in recovery now, but cant boot into bootloader
adb reboot bootloader leads to normal boot
in recovery, the reboot into bootloader option also normal boot
