How to get a phone into recovery mode without unlocking it, with pc - General Questions and Answers

Hello Guys/Ladies
I own a oppo neo 7 (a33f) . I messed up my phone by replacing some files at root/system/bin . After replacing the files suddenly the screen of the phone started flashing (it turns on then goes black repeatedly) and also I am not able to press anything on screen.
And now where the real problem begins ,
this phone is so old that it doesn't have volume up volume down or power button (all physically broken)
and the battery got dead :crying: I tried using different things to press the buttons so I can make it into recovey mode (I can still press the volume buttons using pin but no chance with power key ) but still no chance.
Is there any way to make it boot into recovery mode without using the power button and yes I have a working pc with adb and platform tools but the phone is locked so adb prints "unauthorized device" I cant even turn on the device. I tried plugging it in charger and it works, the charging animation shows.
I have the stock rom that I can flash, I am not able get into recovery without power key.
Please help!
Thanks, in advance.

[Q] Nexus S power Button broken Stuck in bootloop [not rooted]

Hi,
I have an Samsung Nexus S [not rooted] with a broken power button (stopped working after I updated to ICS). So for a couple of months, I was using the "pull batter" trick to power on and off my phone.
Now I am stuck in a bootloop and I can't seem to get out of it, despite howmany time i try to pull out the battery.
I manage to enter into the fastoboot mode screen, but then my volume buttons won't work and I can't scroll up and down the menu.
Is there a way out? I am really a noob at this and haven't rooted an android phone before. Please help!
Thanks
i think the best think is to unlock the bootloader and doing that it will prompt to you asking for erasing all your phone (sdcard included), maybe this hard factory reset will help you bcz like that ur phone will be back to stock ics.
to unlock your bootloader (wich is the first step to root, if u want to) do this:
download this (the entire nexusrootics folder): https://docs.google.com/open?id=0B7O2O1p4iWXTWWxha0pUcXNud2s
put the folder on the root of your hard drive of your pc (for example mine is C:\)
then install the drivers (wich are in the downloaded folder), so plug your phone go to driver management and choose to select the fiolder and select the usb_driver and choose ADB... (first one)
then click windows button+ R and type "cmd" (no "")
now type "cd.." (no "") to go back to the root of your hard drive and type cd (name of the downloaded folder)
now type "adb devices"; if a number appears it means that your drivers are well installed
after that, type "fastboot oem unlock"
on your nexus a question will appear to ask your if your are sure to erase all your content, use the volume lockers to say yes. (if your volume buttons dont work here i think u are stuck)
NOW YOUR PHONE SHOULD BE BACK TO STOCK, WITH THE BOOTLAODER UNLOCK BUT NOT ROOTED so it's safe for warranty issues
please click the thanks button

to lock it back just type "fastboot oem lock"
I got the same problem, yesterday the power button was not functioning properly. And after a couple of battery pulls, I can't start the phone unless I put a usb cable in. The phone starts but it is stuck in bootscreen. If I hold volume up button and connect usb cable + put the battery back in I can get into bootloader (Rooted and unlocked) but I can't navigate in boot screen with volume up or down, and pressing power button does nothing, which btw is clicking when pressed as usual.
I think the powerbutton is continuously pressed, and thats why I can't navigate or execute any commands in bootloader.
Any help to this problem would be appriciated, since I'm working abroad and using this phone as gps here and have no backup phone at the moment.

I got the exact same problem.
Can't backup even through clockwork Rom Manager mod, because when in recovery the power button might be interfering with the scripted backup....
Well mine has weird issues
Every so often if I click the power button it doesn't do Anything or brings up shutdown menu

I'm in the exact same boat. What the hell did Samsung make the power button with??? Mine died on me barely 6 months after purchase of the phone. It's pretty pathetic.
I would like to know how am I able to browse bootloader screen if my power button is dead??
Mine did the exact same thing, I was online chat with Samsung for warranty and all of a sudden the volume buttons started working in fast boot...and amazingly I pressed power after select recovery and it works...right before the volume buttons "unlocked " , I was kinda tapping on the power button trying to get it to do anything, then I saw the USB init and whatnot

How do I fix my OnePlus One’s bootloop?

Greetings of the day,
Hello everyone, I'm having a oneplus one 64GB phone that is not getting start, everytime i connect it with the charger it goes into a bootloop. Yes the phone was rooted and I was using a custom ROM with the default kernel. The issue started when I tried to reset the phone to battery settings. I think I somehow messed the kernel and now it is stuck in bootloop. The problem is that I can't connect it to my computer or put it in debug mode as it just restarts again. Any idea how to actually boot it so I can install the kernel and ROM again?

No, My phone is not getting on but whenever i am connecting it with my charger the phones goes in the Bootloop, and when i am connecting it to My PC while pressing Volume Up + Power Button Pc shows that the Unrecognized devices has been connected.
And i think phone is Hard Bricked. I have tried ADB software and one plus 1 drivers manually but it didn't worked too. I have tried minimal ADB too but it also didn't work.
Kindly let me know about it.

Volume UP + Power should boot in fastboot mode. Volume Down + Power should boot into recovery. First, try to boot recovery.

I have tried both, but nothing happens with it, Volume UP + Power shows the unrecognizable device is connected and Volume Down + Power does nothing it continues with bootloop .
Have you got Developer Options enabled?
Goto About Phone & Tap Build Number until Developer Options is activated. Goto Developer Options> Advanced Restart & enable the switch.
Press power button->Restart->Recovery.
It will now boot into Recovery.
Also have you tried keeping hold of power button whilst it bootloops. Keep holding the power button until it powers off. Then press Volume Down & Power Button to power back up (you might see a slight flicker onscreen that means it should go into Recovery mode). Keep hold of these buttons until you gain Access to Recovery Mode.
This will allow you to Recover or flash a different ROM.
If you're having issues connecting to a computer (Windows) try downloading Windows Media Center for your version of Windows. This will install media drivers to recognize your phone.. If all went well you will get the pop up with A0001 (Codename of OnePlus One). From there you should be able to enter fastboot mode through ADB.
If this doesn't help you, I'm sure that someone else will untangle the puzzle to get your device in good working order buddy. Good Luck.

Stuck at entering fastboot mode

How can I get my Galaxy Note 20 Ultra out of stuck at 'entering fastboot mode'?
Hold down power and volume down until it reboots back to recovery. I got stuck there last week and that's what worked for me.

Is this problem solved? I cannot boot into bootloader mode, thanks!
Switch off the device. Then hold volume up and down buttons and insert the USB cable plugged to PC. You will get to download/odin mode

Download mode is different from fatboot mode, I can enter, and works ok download mode. However, fastboot does not, it gets stuck in entering fastboot mode and no fastboot command works
I got same issue here, I've tried rooting via TWRP and after data wipe and "reboot to recovery" it got stuck in same thing and doesn't move at all, if I hold power and vol down it just boots the device which i dont want since i need to flash magisk as a last step. if anyone encountered this or knows how to fix it i'd be helpful
I'm not rooted but I've had past Samsung devices that I was able to root and if I'm not mistaken Samsung phones aren't able to boot into fastboot mode because Samsung removed the ability to. You can run commands via ADB mode but I think that's about it

Guys, turn off the phone, press volume up and volume down together, and plug the usb cable while pressing volume up and down, and wait until the phone enter in downloading mode. This work for me.

Since we can"t enter into fastboot mode is it possible to flash boot.img with adb commands?
I m having the same problem with a21s(a217f). I can t enter download mode using key combinations and the other way launching it from recovery doesn t work, it stays stuck at,, entering fastboot mode,,
The ROM is already bricked, it says in recovery when i try to factory reset the following error:,, can t mount. /system (structure needs cleaning)
Even with,, apply up. with adb,, doesn t work, it just doesn t get detected on my computer when i checked with adb tools.
! The only thing that works is that I can access my sd card and apply a update from sd card but I don t know where to get the update file. (I ll edit if it works to flash stock rom from,, apply update from sd card,, )
Anybody got some ideas or should i burn my motherboard and replace it?
sorry for bad english
Honestly plug device into PC.
Power off device
hold all 3 side buttons. Volume up and down and power/bixby.
Should usually work.
After in fast boot you must press a button Volume button to find via odin.

I already did that, unplugged the battery, reconnected it after 1min, connected my phone to the computer and pressed all 3 side buttons, still doesn t work. I guess the download mode is deleted or something..
Volume up & down, no side key, then connect to PC. Works for me. Connect to PC first does not work for me.

It wouldn't be deleted as it's a safety protocol if the device has a bad update and freaks out.
Maybe try to person above method.
Normally I can enter download mode with any of these methods if you cannot I'd suggest trying to get the device replaced due to software malfunction

Samsung phones use a tool called Odin to flash firmware. If you're flashing custom firmware firmware you'll need to have your bootloader unlocked.
I got mine into download mode just now. It's a Galaxy A13 .. Like stated above, try to hold all three buttons down and connect to USB. I had to let go before it showed the battery charge icon. From off. If not from off try from charging. I think that's what I did just now. Plug the usb -> let it show the charging icon (from powered off!) -> hold all three buttons, let it power on, let go. DONE.
just follow this video it helped me a lot to unlock my boot loader

Question my Galaxy A12 won't boot to android or download mode help me pls

so I just tried to install unofficial TWRP 3.5.0 on my Samsung galaxy a125m and everything went fine, Odin said done. Then I just tried to start TWRP by pressing power and vol up and it didn't start, so I thought I might have done something wrong and rebooted to download mode and flashed it again, Odin said done, then I unplugged the USB cable and now it won't boot, neither to the system or recovery, even to download mode, it did enter download mode a few times before but I pressed the wrong button and had to cancel and enter again, now it won't even enter download mode so I can't flash stock rom to fix bootloop... pls how can I solve this I'm desperate
when I try to enter download mode by pressing volume up + volume down it just shows up charging mode without any numbers, then it turn on and shows Samsung logo, unlocked bootloader warning screen, and the Samsung logo again, but then just restarts and repeats all again...
when I try to press volume up + volume down + power, nothing really happens...
someone help me please
You need to keep both volume up and down pressed, then plug in the charging cable. It should enter download mode, no need to press the power button like in older samsungs.

yeah I did that a lot of times, it used to work now It doesn't anymore
in this video you can see what's going on, I'm pressing both volume keys and nothing happens
Your browser is not able to display this video.
Is the cable plugged into a charger and on?
Have you considered that your volume buttons may not be working?
Same hear
Try attaching your phone to the PC, and then pressing volume down + power to reset the phone, (for about 7~8 seconds) then immediately press the volume down and up buttons, that's how I recovered from it. Tell me if it worked

Please help it dosent worked
No pc detection
No download mode
No recovery
No charging
Hello, unfortunately in these cases the only solution is to enter download mode, check if any button is damaged or if the cable works and if it is well connected, press the buttons harder, hold down the volume up and volume down buttons at the same time , by pressing the strong buttons, for about 6 seconds and then connect the cable. If you don't try another cable to see if that's the problem there is no other solution as the phone is not recognized by an app that can put it into download mode when turned off the solution is the one I already told you about. I hope you have fixed that problem. Sorry for my bad English.

I am having a similar problem with the Samsung A12 SM-a125u
I never could enter into this "Downloading mode".
I tried flashing the stock ROM through ADB with fastboot, and I have another problem that I've never seen before: ADB can see the device while in recovery mode, but fastboot can't. And so it won't allow me to flash the ROM and I don't even know how Odin is supposed to help yet; I think I needed to enter Downloading mode for that, but I can't get into it.
I'm working on this phone for a friend who was given it because his friend's mom doesn't remember the password to it. Does that matter? It's worth noting that because of that I cannot get in to turn on OEM unlocking or dev mode, but idk why that would come into play in recovery mode. Also, the model indicates this is an AT&T phone, and tutorials online have acknowledged this model in their "applicable models" list at the beginning of their tutorials, but I know that carrier phones can cause problems all over the place (stop buying carrier locked phones people!); is this a problem?
How the heck do I flash the stock ROM to this this?

Nokia G10 TA-1334 Black Screen

Hey Guys,
I need help with Nokia G10 TA-1334. After the loading screen the display becomes black. Only thing I can do is holding the power key and the menu appears with lock, switch off and restart. Tried to reach the recovery mode but no key combination would bring it. The only menu I can reach is the fastboot menu, but the debugging mode is not switched on so the adb commands are not available. Can you please tell me a working key combination for the recovery mode. I also tried flashing it with sp flash but again it is not working. I tried again different key combinations. The phone is connecting to the pc normally but without the screen I can't do anything.
So Far I Tried these:
With plugged in cable:
Holding Power + Volume up is only restarting the phone
Holding Power + Volume down - fastboot ( but there is not any additional menu)
Holding Power + Volume down and when android logo comes holding only power and fast press volume up
Holding Power + Volume up and down = nothing
Hi Ivan, my G10 has had exactly the same problem as yours since Friday. Have tried the same things as you and also had no success. I tried draining the battery to flat but that didn't work either. Have you had any luck finding a solution? Thanks, Tony
For now nothing, the draining wont work probably because I disassembled the phone and disconnected the battery. After that no change has occured. I hope that somebody will provide a working key combination for the recovery mode.
hello, nokia g10 and the same problem, did you find a solution?
Hi guys.
Did you find a solution to this problem?
Same Problem, we can reboot to Android Bot with NO COMMAND prompt, but hard to enter recovery menu with the combined power key & Vol+ key.
Is there someone know the new version how to enter recovery menu? Tks.
