I do "download upgrade" by SP Flash tool and its still not working.
I do also Firmware upgrade by SP Flash tool and still black screen.

[Q] How to boot in recovery console on Lenovo A5000

Hi guys,
title speaks for itself
I have tried every single method that came up from google:
Recovery Mode Lenovo A5000
Turn off the device
Press and hold Volume UP key + Power Key for a few seconds
Release all key when Android Recovery Mode appears
Use Volume keys to select
Use Power key to confirm
Click to expand...
Click to collapse
The combination should be-->
-->Simultaneously press&hold Power button & Volume+ and Volume- (Yes,both volume buttons).
If by using this combination the phone just shutdowns or restarts.....Simultaneously press&hold Power button & Volume+ and Volume- >Release all buttons when the Lenovo logo (the first static logo) disappears.
Click to expand...
Click to collapse
...or use a sequence--> Simultaneously press&hold Power button & Volume+ and Volume- -->Release only the Power button when the Lenovo logo appears-->Keep on pressing both Volume(+&-) buttons until you enter the recovery mode.
Click to expand...
Click to collapse
don't remove your fingers until it boots up.. much better if you press first the volume keys before you power on.. keep pressing all together until it opens. or you might end up booting the chinese recovery.
Click to expand...
Click to collapse
With Vol Up+Power button managed to get this:
Select boot mode:
[VOLUME_UP to select. VOLUME_DOWN is OK>]
[Recovery Mode] <<==
[Fastboot Mode]
[Normal boot]
Click to expand...
Click to collapse
i can change selection with Vol Up (move arrow), but neither Vol Down or Power button acts like OK button
Tried to reboot to recovery from app it returns "no command" error.
After that i found what is key combination (i think) hold down volume up and down and power button. after 5+ seconds release power button, but keep pressing volume buttons. But no command error again.
I really need recovery console, cuz i want to install xposed but if i get stuck in bootloop will...well, will get stuck
Well, also tried to plug-in USB cable while holding Volume UP ad Volume DOWN buttons, to see will it shows in adb. Result is "no command" again. But i can see device attached when using build-in cd-rom + usb debug enabled
For me , Button Combination never Works Exactly , but when i Reboot into Recovery (using Rashr app etc) , then same No Command Window Appears and then i Press Power Button Again and Recovery Window Appears... No Command Error Shows , Simply Press Power Button again Like for 0.5 Seconds , Recovery Screen Shows Up, Works for me.. ...
And also me Using Same 4.4.2 , i installed Xposed (Not From Recovery) and Never Got a Bootloop...
For Now i am using TWRP , Working Well , But Still Button Combination is Really Annoying For me...
Yeah I have very large fingers and those damn buttons are very small lol so its aggravating, but a real life saver when everything is frozen rock solid ..try that button combo on an LG g4 , its taken me an hour of reboots to finally get to recovery, why put such tiny hardware buttons on the back of the phone ffs
Through my ancient eyes comes the certainty of decay... LG G4 & L 70
Thanks guys, but i've managed to flash TWRP recovery and don't have No command error, anymore

Power Off Your Mobile , Now Press Vol+ , Vol- and Power Button all At the Same Time Until your Phone starts again and you See Lenovo Logo (Below Written Powered By Android) , then after 5 Seconds Release All .... Now wait , and you'r in Recovery Now .... Works For me...
Or you can Try "adb reboot recovery" , this one works for me too...
If None of these Working , then Re-flash Recovery and Check again (Try flashing Recovery Using different Method Like using Rashr App)...

Hey guys do you hapen to have a solution to my problem:
My A5000 won't shut down properly, it doesn't vibrate at the end of power off process and from that moment on it gives no any further life signs... I somehow managed to turn it back on but it totally drained my battery over night... (btw i turned it back on by simply holding power button for approx. 20 seconds)

Well, Stock Recovery never opened until I flashed a custom recovery (TWRP). ?

[SOLVED] Lenovo A536 - how to reboot to recovery mode

Hello, I have a big problem with rebooting to recovery mode. I can reboot to recovery only with application. If I turn my phone off and then hold volume up + power, then I get black screen with only one yellow Chinese text on the very top left side and then after 1 minute it's get into Chinese recovery.. My question is: how to get into custom recovery without using applications like for example "Quick boot".
I need it, because I have to install ROM again, because I did a big mistake, when I deleted one file from the "system" folder. Now my phone boot without problem, but after that everything is lagging and all applications stop working, then it automatically reboot phone..
I can't flash firmware with SP Flash Tool, because of Windows drivers. My laptop does not recognize the phone. It says: "Unknown USB device".. That's why I need to get into custom recovery for installing ROM.
Thank you in advance for help.
This helped:
With the phone powered off
Hold Volume Up + Volume Down + Power button
When phone vibrates release power button only.
As the No Comman Screen release all buttons.
Press and hold the power button and tap the Volume Up button.
Release the buttons. You must get into recovery mode.

SM-A750F: How to exit download mode into recovery mode?

Hi,
A7 2018 (SM-A750F) vanilla
I am trying to flash TWRP on my phone using Odin: entered recovery (VolUp+Power), choose Bootloader to enter download mode, blue download screen is visible, flashed TWRP via Odin, Odin reports success.
But then, the only option to leave download mode is VolDown+Power which results in a normal boot which in turn restores the default recovery.
So what am i doing wrong? How can I exit download mode straight into recovery?
There is many tutorials on the web for A7 2018 but most seem to use different key-combi's that don't work on my phone.
When you're in download mode keep pressing all 3 buttons ( volume up + volume down + power), around 7 seconds. When the screen will go black, immediately remove your hold from " volume down" button and you will be left with two buttons. volume up and power which are used to go in recovery, when you'll hear a vibration. Remove your hold from all buttons and you'll find yourself in recovery mode
In simple steps (They're Same) :-
1. Press all Available Buttons (VOLUME +, - AND POWER BUTTON) For Around 7 Seconds
2. When Screen Goes Black immediately Remove Finger From Volume Down Button
3. Don't remove fingers from Volume up and power button ( keep hold onto them)
4. You'll hear a vibration
5. Remove your hold from those buttons too
6. Congratulations, you're into recovery mode
Yes, that worked.
However on my phone the combi to exit Download is Down + Power and for Recovery is Up + Power.

Same Problem With My Realme 2 RMX1805
I was formatting the phone as it was lagging a lot. It's been in bootloop since that restart. Formatting screen popped up once, but it again got restarted. Realme service centre guys told me that they don't have software to resolve this. So now I just have a dead phone and no one to resolve this

Mi Samsung doesn't turn on!

I rooted my phone yesterday, so today i wanted to install twrp, but when i turn off my phone and tried to go unto recovery menu the logo just turn green and and the screen went black. I tried to start the download mode but is no answer, so i thought that the phone was bricked, but when is bricked you can access to the recovery mode, all i can do is press volume-down + power-btn and there i got the samsung turn on logo but then i have the same green logo and the black screen again.
Somebody can help me pls!!!
Try this: Connect usb with pc. Hit volume down + power button till screen goes on and at the same time screen goes on release power button and hit and hold volume up and down button, this should get you into download mode and flash stock firmware with odin
