I have an old lenovo k8 note it stopped charging one day and was not booting, so i replaced the charger board with another one i found online. It started charging but displayed nothing even after i press the volume down + power button. But when I charge the phone it booted into meta mode and does not display anything except the boot logo. I tried changing the charging board ( read somewhere that it might be a hardware problem ) but the results were still the same. I tried flashing stock rom, it is still in meta mode. Can't open recovery mode even though i pressed volume down + power button. Can't use adb to fastboot. How do i exit from meta mode

I was provided this device to try and help resolve the issue. I am not sure how it got to this point. I believe that it was rooted with a custom ROM, then the individual tried to install a stock ROM (method unknown).
The current situation is:
Galaxy Tab S 10.5 SM-T800 stuck in a bootloop with the TWRP logo on the screen. I can not get the tablet to go into download mode. I have tried all of the different methods to enter download mode, i.e. Power & Vol - & Home, Drain the battery > Plug into PC while holding Vol - & Home, Power & Vol + & Vol -. None of these combinations do anything. The only thing I can do to get a response is to press Power & Vol +, which reboots the device right back into the TWRP loop after the Samsung Logo. Power button alone does nothing.
The device is seen by Windows with the Samsung Drivers but is not mounted to a drive letter, and I can not mount it.
ADB , fastboot and Odin do not see the device.
I would like to flash a new rom either custom or stock, but I need to be able to get the device into download mode so it can be seen by odin.
Any help would be great.

Probably just timing and pilot error this one. I've never known of any Samsung device boot but be incapable of booting to download mode as download mode is bootloader related.
No working bootloader means dead device.
No matter what state the device is in at the moment with the usb cable removed, hold POWER + VOL DOWN (not up) + HOME until the Samsung boot logo comes up, hold for another couple of seconds then release. Download mode should appear.
I know it should be easy....
I know it should work but it is not, I will make a vid of the process and post. I can not make heads or tails.

Is the home button actually working, are you pressing it firm enough?
If the home button doesn't register then the tablet will simply reboot.
Its a bit odd why twrp doesn't fully boot though unless it's the wrong one.
Does it hang at the twrp logo or continually reboot?
I've searched extensively about bricked P600's and found a few threads where it seems it's still possible to boot into 'download' mode (Home + Vol Dn + Pwr) and from there it's possible to flash TWRP or some kind of recovery.
Unfortunately after attempting a flash I don't even have the capability of booting into either recovery nor download. All I get when I power on the tablet is the Samsung bootsplash and then black, dead screen (backlight is on).
Going through the process to boot into download mode then plugging it into USB + ODIN doesn't show up as a COM device.
Am I hopelessly at a loss?

When you tried to get into download mode, do you see the samsung screen turn on and off??

Yes, it flashes on the screen for a second before going to black screen.
*Edit: I've found that the tablet now wants to stay 'on' all the time. Long-holding the power button turns it off but it will immediately turn on again. When it's on external power and just switched off, the battery charging animation starts (with the spinning circle) but doesn't go into the animated 'bubble' charging display - instead it goes into the typical black screen with backlight on.
Samsung J2 (J200G/DD) not booting (no logo, no vibrate), not into recovery (Vol+ + power + Home), not even into download mode (vol- + home + power), after it suddenly shutoff on it's own while in use (call). There was vibrate when it shut off (as normal shut down)
Battery checked, no problem. No response to charger input without battery. USB debugging probably not on
What can be done. Please guide.
Could not find any related problem/solution in forums.
Is there a possibility of hardware issue? Similar problem seen by any one, on this or on any other models? I have a similar problem on a Lenevo A6000, difference is that it goes into boot loop on connecting to charger without battery.

Hi
i have the same issue on my Samsung galaxy SM-J200H right now! it is happened after flashing Stock Android LP 5.1.1 with Odin.
Do you fixed Your phone?
Edit: no way The device dead! i am changed the motherboard.
this problem happening when we flash the wrong security code of the ROM.
you will tell me i am flashed my Device ROM
Yes i am agree with you but some ROMs will not matching with all phones.
at the end of the ROM name have ex. U1 , B1 or U2 , B2 we should make sure which one is for our devices type.
This thread only introduce hardware methods to enter specific modes, however, if possible, use software method like advanced reboot, adb reboot, magisk reboot, etc. instead for stable entries.
Force reboot: hold both volume- and power keys for 8 seconds (maybe reboot at the 9th second, so hold until the screen changes). This can quit any other mode. Somebody says if you can count time accurately, you can just shutdown the phone instead of rebooting, but I have never succeeded
Normal boot: when your phone is off, hold power key until your phone vibrates (if your phone can boot to system).
Safe mode: during normal booting, when you see the dynamic animation of LG (not static monochromatic logos), hold volume- key until the phone vibrates (you can start holding it even earlier, but make sure holding it until you really enter the safe mode). In this mode, only system apps, default settings and basic functions are enabled. Any reboot quits this mode.
Recovery (stock for master reset or custom twrp): hold volume- and power keys until the initial boot screen of "LG V30" with "powered by Android" displays. (If you have unlocked the bootloader, this screen would display twice, but only the first time is what we are talking about.) Immediately release the power key and hold it again (in other words, pause holding the power button for less than 1 second). Then after the screen changes, release all keys and do further steps according to the instructions displayed.
LG download mode: shutdown your phone first. Hold volume+ key and connect the phone to a working computer via USB. Then the phone should boot to download mode.
Fastboot/Bootloader (if any): similar like the download mode, but use volume- instead of +. However some firmwares may miss this mode. If it works, it should boot to the fastboot interface immediately and you can power off the phone there.
Information screen (I don't know what it's called exactly): shutdown your phone first. Hold all the three of volume+, volume- and power keys, and this will lead you to a screen listing MEID, IMEI and S/N of your phone with corresponding barcodes.
Qualcomm 9008/EDL/QDLoader mode (sometimes even called Qualcomm download mode, but not Android download mode) (mentioned in One way to force shutdown your phone, try this if other modes do not work): connect your phone to a working computer via USB. Hold volume- and power key, around the moment your phone force reboots press volume+ for multiple times (with holding other keys). In device manager on the computer, see if a device named something with "Q" like QUSB_BULK (no proper driver installed) or Qualcomm EDL HS-USB 9008 (proper driver installed) other than anything containing "Android" or "ADB", the phone enters the 9008 mode. If not, unplug the cable and try it again. This can turn off the screen. If you find difficulty to perform it, you can also try other more general methods like test points shortening (see test points lg v30 plus for 9008 mode) or engineering cable (not tested yet).
Yet there is no way to shutdown the phone directly with simple key combination, but you can refer One way to force shutdown your phone to make it if you cannot use regular methods to shut your phone down.
If anything missing, please reply to let me know
Hi everybody, yesterday I was playing with my old Galaxy A50 trying to install a custom rom unsuccessfully.
I repeated the procedure three times installing TWRP and then Havoc OS but every time I tried to reboot from TWRP to OS I was stuck at the warning screen saying that the phone bootloader was unlocked and booting into download mode to reflash TWRP was blocked as it showed "only official binaries can be installed" (yes I installed Samsung disabler but still).
Still I was able to get the phone into download mode and reinstall the stock firmware as it seemed to be the only way to install and boot TWRP.
But at 4th time repeating the process I got frustrated, shut down the computer and left the phone on the warning screen still connected to computer usb cable.
Then I got back and noticed the phone was off as the battery died.
Indeed the battery died, so I put the phone in charging and after it reached 100% I tried to boot into download mode again to reflash stock firmware.
But here's the strange thing, I cannot boot into download mode anymore as pressing vol up+vol down while connecting usb cable, shows the lightning charge logo for 5 secs and then reboots infinitely with the same pattern.
If I force reboot by pressing vol down+power it shows the Samsung logo with the warning below it, then skips to another screen with another warning suggesting to press power button to continue (which does nothing) and after a while reboots to samsung logo.
So it doesn't seem it is bricked, it looks more like a battery controller fault, so I tried to detach the battery flex from the board, hoping it would reset the controller but it's still the same.
Also I tried with the flex detached and still no download mode is possible.
Was the download mode somehow erased? (if it's even possible considering it's the motherboard firmware)
If you need photos, videos or even a call on zoom, Skype, webex I would be glad to show you
same i got the same problem i can't find nothing for this when i press volume up and down and put the otg cable its simply charges but it gets stuck on the logo image there's no way to fix this but the only way is to open the phone,change the emmc and put one from samsung,close the phone flash a custom rom and you are done.
If you can enter recovery, do it. As soon as your phone gets into it, select the power off variant and then try to enter the download mode.
It seems like you did not unlock the bootloader, did you?
The bootloader Is unlocked i can't enter in the recovery because the phone locks on charging logo and its fully charged but when i try without charger It doesn't start.
