How to resolve boot loop problem on android PumpKinx 10.1" tablet

I've android PumpKinx 10.1 tablet with 5.1 Lollipop android os.
I did take backup of its stock recovery image.
Since there is no custom recovery image for this device I tried to flash it with twrp recovery image. But after running below command, device goes into bootloop. I've tried many methods but no success.
fastboot flash:raw boot twrp.img
Any help would be highly appreciated. Thanks in advance.

maybe u have locked bootloader. First turn on oem unlock in developer options, then reboot in bootloader and type
Code:
fastboot oem unlock
Then confirm acion in the tablet whit volume up, then the bootloader now is unlocked.
Note: The tablet get soft reset. Make backup first.
Then try flash the recovery

Do you understand boot loop or not? First of all fastboot is already unlocked otherwise how I will be able to run above command and since my device is in boot loop then how can I go to developer option?

Just send them an email asking for stock firmware with flash tool, along with the purchase bill..
Or if it still has warranty, just go to the service center and say something like you over-charged the phone a complete night & since then it's not working and claim warranty..

Have you tried to wipe the cache partition or even factory reset???

What happens if I disable OEM-Unlock in developer settings?

I already unlocked the bootloader, happens anything if I turn off oem unlock in developer settings or will the bootloader relock?

Turned it off once by accident but turned on again.. Nothing changed

I don't think anything changes unless u relock it via fastboot, which at that point as long as u can boot back into the OS, u can always unlock it again, relocking bootloader will format ur data and u will no long be rooted or have twrp installed

locking your bootloader with root etc installed can cause major problems so before doing that you should flash a stock firmware otherwise you will be locked out

Why would you want to do this? There is no benefit to it if you plan to stay rooted.

Need to find something to do. You bored

I want to disable developer options, but if I do that OEM-Unlock automatically turns off and I don't want to reboot because I dont want that I lock myself out.

Your cat will get knock up..........again!

Just turning off Developer Options won't relock your bootloader. You can only do that manually in fastboot. But you'll also lose USB debugging, which means adb won't work anymore in case something goes wrong. (But leaving USB debugging on all the time isn't the best idea anyway.)

Hello everyone
I think I did that mistake
I have twrp installed on my phone Samsung SM-G532F . my phone was working just fine but I have locked the oem for no reason .
now when I turn off the device and tried to turn it on it shows { Custom binary blocked by FRP. (boot. img) }
and when I open recovery mode it shows { Custom binary blocked by FRP. (recovery. img) }
the download mode is working and shows that the FRP lock is on .
I tried to flash the stock recovery with odin but since the FRP is locked it failed .
the adb is not working because the device cannot boot , even the battery symbol when I plug my phone with a charger is not displayed and shows the error { Custom binary blocked by FRP. (boot. img) }
any ideas will help a lot .

You cannot boot with a custom recovery and a locked bootloader. As to how to fix this, you need to ask in the Samsung forums. This is for OnePlus 6.

If you have a oneplus look in the forum for msmdownloadtool and follow the steps, you can revive your phone.
If your phone its a samsung, search in samsung forums for a tool to unbrick your phone.

I downloaded and flashed the official firmware with odin and it worked . thanks for the reply

I did this once on my OnePlus X, disabled oem unlocking in developer options. phone and recovery worked fine. I did a backup. Flashed a new rom to test it. The rom had AOSP recovery in the zip, overwriting twrp (opx has separate recovery partition). I flashed gapps affter the rom and the setup wizard was crashing so I could not boot in the home screen. Tried TWRP, its gone. Tried to boot to twrp via fastboot, oem locked. Had to do hard brick reset. Backup and data, gone.
TLDR, you should leave it on, unless you are on stock firmware.

After flash a rom you must flash twrp recovery again, restart in recovery and flash gapps and magisk

First of all you have to flash combination file associated with your device model through ap slot of odin.
Then your phone will turn on and you can access settings through which you can turn on oem unlock.
Then you can install your desired rom into your device

I also accidentally turned off oem in rooted phone , Does my bootloader locked or I can safely reboot

I restored the stock firmware using Odin, but now I see that the bootloader is still unlocked.
When try to lock it again the system says: "If OEM unlock is turned off, your phone will be reset to factory default settings after restart. This will erase all of your data... " etc.
My question is: will the firmware be still in place? I don't mind everything being wiped, because most of it will be restored anyway when I login to Google and Samsung again.

I believe that relock is impossible and but to make the device recovery to installed status of stock rom keeping with unlock bootloader.
Please see my post. May make it help or not.
When I try to burn rom with TWRP, img burns but it doesn't start and zip gives an error and cannot burn.
When I first burned custom ROM (unofficial AEX), it did not start, so when I deleted the data from TWRP, it seems that I deleted things that should not be erased, so even if I burn it from the zip file, with the error message in the image below I...

Unable to unlock the bootloader

I've recently bricked my device trying to install LineageOS, long story short I had to use MSM Tool in order to flash a new, stock ROM. Since I did that I am unable to unlock the bootloader: everytime I do the phone bricks with this following Yellow message on the screen: "upgrade download failed please check your download flow is right". After that I have to use the MSM Tool again to unbrick the Yellow text.
Any ideata how I might unlock the bootloader? Aside from that, the phone works fine.
EDIT: I managed to fix this by OEM updating my device to Android 11 and *then* unlocking the bootloader. Another issue has arisen now, though: whenever I try to boot TWRP from fastboot, the phone reboots and gets stuck in the "Fastboot Mode" OnePlus logo screen. Would anyone know how to fix this, or maybe is there a way to root your phone without using a custom recovery?

Yes you can ,,install thru boot loader with ADB and fastboot CMD. First you need to extract the boot.img from your oos rom, patch it in magisk app, then put it in your adb folder and run the cmd " fastboot flash boot boot.img .

Why you want to lock bootloader ? Install custom ROM is need unlock bootloader. Why you first unblock it and then block it. Officially rmx1971 can run until android 11, with custom ROM it can install new version. What you need do is. Go to bootloader download my TWRP if you are on Android 11 and flash it
Fastboot flash recovery recovery_3.6.2_11.img from there you have to install custom ROM.
