Alternative ways to open recovery - X 2014 Q&A, Help & Troubleshooting

Hey guys, My victara's volume buttons (both) stopped working after a drop. I was flashing a new rom in it today and forgot about this detail, then, I wiped the wrong partition via TWRP and got a boot loop (easily fixable, when possible) but now I can't enter on my recovery without the volume buttons. I've tried doing it via adb of fastboot but none of them recognized my device. There is a third way to open recovery or bootloader?

When I reset it with USB plugged in, it turns the green led on for 2 or 3 seconds and go back to bootlooping

I was able to fix my volume buttons with some silver tape on the connector and everything is back to normal now

If you are rooted, there are a variety of apps that will reboot into recovery or bootloader. I use ROM Toolbox Pro, but there are others

Adb wait-for-device reboot recovery
Issue this command without the device plugged in. Then plug the powered down device in and it should go right to recovery. It's a good trick to keep around for the future.

I haven't seen that command before. Nice one.

[Q] Installing custom rom, on galaxy s gt-i9000, with a busted power button

Hi there i am relatively new to android modding and rooting etc. I recently tried to install Cyanogenmod to my phone and I succeeded, but the next day my phone began to restart itself, turns out that the power button is broken. We tried to repair it but ended up burning down the processors internal i/o (latch or whatever structure it has) with a faulty multimeter :crying: . Now i have to turn on my phone with a dock cable :silly: (with 1kohm res) which wakes up the phone, i can access the Download mode by plugging in the dock, and pressing home+down, but the recovery needs the power button signal too.
I can access the recovery by using adb commands, but i need to boot in. If i install a new recovery like CWM, i am stuck in a bootloop and i don't know if i can use the adb commands. Is there any other way to get into recovery mode, besides home+power+up, or adb commands?
Can i install CM onto the phone under these circumstances?
Thanks for any help given!

[Q] Rooting HTC One Mini 2

Is the One Mini 2 possible to root? I've seen a lot saying 'not yet', but it's all fairly old. If so, is there a tutorial/walkthrough somewhere?

yes root its possible for htc one mini 2.
1- use htc dev website to unlock bootloader and choose all other supported phones. Follow directions.
2-Flash recovery TWRP and flash superuser.zip.
Google it or find in forum tutorials for 2nd step.
I've tried searching, but all I can find is either out of date and stating there's no solution yet, or applies to the original Mini, not the Mini 2.

http://forum.xda-developers.com/one-mini-2/help
I got that, it's the "flash TWRP and superuser.zip" that's the issue.

1- Download the TWRP Recovery file here and copy it to the C:/Unlock folder created in the Bootloader Unlock Tutorial or the folder you use for HTC unlock
2- Now use the Shortcut “Windowskey + R” and type cmd into the textfield. Press OK to start the Shell.cmd
3- Now we need to navigate to our Unlock Folder by using the command “cd c:/Unlock“ (without “”) and pressing enter
4- Power off your HTC One Mini and boot it back up while holding the Volume Down and Power-Key until you see the bootloader
5- Select “Fastboot” with the volume keys and press power to select
6- Connect your HTC One Mini through original usb to your pc
7- In the Command-Window enter the command „fastboot flash recovery "twrp-2.7.1.0-20140802-memul.img“ (without „“) and press enter
8- The Installation should only take a few seconds and will give a short reports at the end
9- Your HTC One Mini should now have the TWRP Custom Recovery installed
TWRP will try flash SuperUser, it didnt work for me so,
Send UPDATE-SuperSU-v2.02.zip to sdcard and use TWRP to flash it
You must have updated drivers (install htc sync) and original usb cable.

I got TWRP in. None of the buttons worked. Eventually the screen went blank, I powered back on and just got a 'swipe to unlock' screen. Couldn't swipe, either. So...somehow the touchscreen isn't working?

Try and reboot the phone by holding volume down and power for 10 seconds.
That doesn't do anything. Seems like the only button that does anything is power, and that just turns the screen on if it's off, or to full brightness if it's dimmed (which it does for a second or two before turning off).
I've kept the screen on and managed to run the battery down to 52%. My plan at this point is to run it completely flat, forcing the phone to shut down, then charge it up a bit and see if I can boot. Beyond that, I'm out of ideas and even if I manage to reboot I don't see how TWRP's going to magically start working.
It boots into Android by default, right? And you have to use the Fastboot menu to get to TWRP? No idea how I got to it the first time, actually, and it's been years since I've used it on my old phone.
EDIT: It's TWRP v2.7.1.0. According to the website, the newest version, 2.8.0.0 "[fixes] a bug that caused weird graphics and touch issues". Should I be using this version instead? It doesn't seem to support the Mini 2.
Check this http://forum.xda-developers.com/showthread.php?t=2394744
Try holding power under a bright light..
turn screen off. and under bright light turn it back on. see if it works
No dice. Down to 15% battery at this point anyway, shouldn't be too much longer before it's flat. Then, fingers crossed it works.
How do I get back to TWRP? Fastboot then select 'recovery' (I think I recall that being one of the options)?

just to be on the safe side, i would stay in fastboot and re-flash TWRP
The battery finally went flat, but then as soon as I plugged the phone in it booted into TWRP...which still doesn't work. Have unplugged it again. No idea where to go from here. Tried the "adb reboot bootloader" command from the thread you linked to, and all it did was boot right back into TWRP.

this happened to me, just hold power + vol down + vol up for 10 seconds, phone will reboot.
edit: whilst doing this dont have the usb plugged in. I have noticed having the usb plugged in, a restart sends it straight back to twrp - hence the same issue.
It reboots straight into TWRP when plugged into either the wall or my computer, and just shuts down when not plugged in at all. Can't get it to boot at all, with either volume down + power or just power, but the second I plug it in it boots TWRP.

ok try, plugging laptop usb port and hold power + vol down + vol up together for 10secs.
Left it plugged in for a while, let the battery build up, and managed to get it booted into Android. So that's a start, at least.
So: fastboot, "fastboot erase recovery" then "fastboot flash recovery twrp.img"?

fastboot flash recovery twrp.img should override. i would also download another version just in case that one is corrupted
this is where i got it originally
http://forum.xda-developers.com/one-mini-2/orig-development/recovery-twp-2-7-1-0-one-mini-2-t2801370
You mean another version from another source, or another copy via that link? Not sure where else to get a copy; I assume you get links from the TWRP website after selecting your phone model but the HTC One Mini 2 isn't listed.
I saw somewhere that simply overriding could cause problems, therefore it's best to erase first?

Check post above this.
TWRP for htc one mini 2 its not yet avaiable in the site, so this is custom.
I have send another file mega https://mega.co.nz/#!C9sRXCAC!OKDm7Df5o95elxtSnF19hiLgsjKn8nq0KplYL9KriIc and changed instructions
or you can get it from the forum http://forum.xda-developers.com/one-mini-2/orig-development/recovery-twp-2-7-1-0-one-mini-2-t2801370
Good luck

Power on not working

I have the following problem: Out of a sudden my volume and power button stopped working. I could still wake it up with the camera button for 2 tries but after trying a couple of things (long press, combinations etc.) the phone went off at some point. Now I'm not able to turn it back on again.
When I plug in the charger, the phone shows the charging screen. I can press Power+VolUp and get vibrations and a restart (to charging screen) but nothing else.
When I plug it into the computer it boots into fastboot. I'm able to submit commands via fastboot but no response via adb. (I found a tip issuing 'adb shell input keyevent 26' but adb does not find the device) using the various reboot options (continue, reboot, reboot-bootloader) only gets me into fastboot again or charging screen.
How can I get my phone back to work preferably without loosing any data? I still have some important stuff on the internal memory and would like to back it up. So reboot into recovery and backup via adb would also be ok, but I can't get into the recovery.
Infos:
- Phone is rooted via http://forum.xda-developers.com/z3-compact/general/how-to-root-backup-drm-keys-t3013343 running '23.4.A.1.232 - Unbranded - CE1 [Central Europe] (1288-7915)' after an update. (older version with root installed via instructions, update self-rooted (via PRFC) and installed 1 month later)
- VolUp+Power in charger only gets back to charging. No change
- VolUp and/or VolDown then plug to PC only gets to fastboot
- Reset switch does nothing at all
Edit: For some reason I could boot it now without doing anything. Saving data like hell... But Power button and VolUp still not doing anything. Camera button and VolDown works... What to do?
Edit2: I tried 'adb reboot recovery' to reflash the pre-rooted ROM but it only went into fastboot mode and I'm where I started... Can't turn it on...

Bricked but recognized in fastboot and recovery

Hello, it's my first question on XDA but I really like this community. So for my problem : after bug in lineage os I wanted returned on the official ROM but after flashing (with my flash tool) the phone doesn't want turn on, the screen stay black no vibrate no LED. On my computer the phone was sometime detected as a MTP devices. So i turn the phone on the fastboot to flash but went he is on fastboot the screen doesn't wake up but on the computer the phone is on fastboot and I can flash. After I tested the recovery so I flash TWRP and boot on this but the screen doesn't wake up but with ADB tool I see my phone and I can move in the phone with "adb shell". I tested all the thing I know to unbrick my phone so I answer you. I really thank you if you can help me.
PS: I don't speak very well English so I really sorry for all the mistake
Absolutely identical situation here, but for me the phone just died by itself at night. Reflashing stuff with EDL / Fastboot does not help at all.
With some combination of boot AND recovery it is visible as adb + mtp device, with some does not.
Should be noted that fastboot boot recovery.img does not boot recovery and loops, but holding up button while inserting usb cable does.
@Celeste.cote
@skydev
Usually you should try removing and reinserting the battery, but the Mi5's battery is not removable, as you know.
So what you wanna do is to force this behaviour by pressing the power + vol up + vol down buttons all together for about 1 minute (be serious about this - also try like 2 minutes if it doesn't work quicker!).
You'll notice that it has been working by seeing the Mi logo.
Solved the black screen of death error for me once.
How about you?
@Phil_Smith, thanks for the advice, well, it seems that the problem we have is a little different.
I have that behaviour (black screen + adb + mtp) sometimes only when trying to boot recovery, but when trying normal boot i get bootloader bootloop with "Mi logo unlocked".
I think i should make a thread for my own problem.
P.S. I think the power supervisor should shutdown (restart) phone if power button is being held for 10 seconds, except if in EDL mode!
I can also recommend doing poweroff from adb shell and removing USB cable immediately afterwards - it should power off the phone.
@Phil_Smith y really thanks you for your answer but that don't running on my phone... I think it's the motherboard who is broken because I have no vibrate no led and no screen. I give up for this phone... Thank you and @skydev I hope you find a solution

Unable to enter Recovery mode after reboot from twrp or stock recovery.

Moin,
My phone was one day suddenly unable to boot into system nor Recovery, but could still enter fastboot.
Took me a while to figure out that USB Hubs let flash attempts fail too. (you can watch the drama in my older posts)
Now i was able to flash System back into a workable state and it looks like that recovery is also successful flashed.
BUT...i can enter recovery only ONCE per Vol - and Power on Button.
i have NO OTHER WAY to enter Recovery at all. i have no reboot option in system (LOS 18.1).
In fastboot/adb command and after one succsesfull reboot per keys, it always stuck after the Sony logo into a black screen. i then have to restart it into system with Vol+ and Power (one vibration) or shut down with vol+ and power for 6 seconds (three vibration) to get it either into fastboot (Vol+ and USB connect) or system again. then i have to flash it again to get into TWRP once. i tryed the latest twrp version (3.7.0) and one older version (3.3.1) that had once worked until the phone broke.
Any idea what is going wrong here. i have already try to completly wipe everything from the phone and try to fix SEL Linux in twrp. nothing seems to work. Did i miss something?
/€: Now it is again in the full broken state. recovery nor System won't boot anymore and end in a black screen.
/€²: Found the Problem: my lilca zip was polluted with altered files i forgot about.
