I flashed TWRP to the device successfully, and proceeded to try to install Magisk 19.3 zip. It would begin to do a recovery bootloop. I fixed it using TWRP, and tried using the patched boot img from magisk manager instead. This is where things go wrong. After flashing boot.img, the phone refuses to boot, and asks me to do a factory reset. I did this twice, and the phone continued not to boot. I then tried installing the latest android Q factory image. The flash failed, and the phone stopped showing up when I do fastboot devices or adb devices. It is stuck in the bootloader telling me slot b is not bootable. I have tried different ports, but adb and fastboot are no longer responding.
Take out the battery for 10 sec or more replace, see if you can get back into recovery. Recovery should be TWRP.
You may need to uninstall and reinstall the driver on your computer. IF it is a Win computer should show up in device manager at the top under Android.
https://www.xda-developers.com/how-to-install-custom-rom-android/
or you can do a factory reset which is also a button.
I fixed it by holding down the power and vol up buttons, which allowed me to use fastboot again and fixed everything. Thanks for the help tho>

I have searched a lot on google and xda and havn't found an answer to my issue. Either I'm searching for the wrong thing or I have a very unique problem.
My basic problem is on two Nabi 2's I can't access the bootloader in order to be able to fastboot TWRP (or any other recovery). It just perpetually hangs.
Both tablets boot just fine. Both tablets are on 1.9.37. Both tablets can be factory wiped via the stock recovery.
Both tablets were rooted via TWRP 2.3.3.0 a few years ago in order to install gapps. I wanted to be able to upgrade the tablets to JB when it came out so I used Nabilablite to "return to stock". I followed all of the prompts and it appeared as though everything worked as desired. I downloaded the OTA update told it to install and never looked at the version again...I just assumed it installed. Handed the tablets back to the kids and everyone was happy. Apparently all I did was flash the stock recovery because they are still rooted and have gapps after several factory resets.
Now (a year later) I have realized I was a dufas and didn't actually effect the change I wanted.
If I hold Vol+ & Pwr buttons it loads to the recovery/boot menu with "boot normally" "fastboot protocol" "recovery kernal" and "forced recovery". If I boot normal, the tablet works fine but I can't update via OTA.
If I choose fastboot protocol it just hangs...for ever...HOW DO I FIX THIS!?!?!
If I choose recovery kernal it loads the stock recovery but still wont install any update OTA or otherwise, even from the sd card.
If I choose forced recovery nothing happens, it also appears to just hang.
If I hold Vol- & Pwr button the nabi logo flashes then the device turns off.
If I hold Vol+ & Vol- & Pwr buttons it appears to be the same as just Vol+ & Pwr.
With the tablet on and fully booted I can see it via ADB. I tried using the adb restart bootloader. The tablet reboots but then just hangs never actually loading the boot loader...
I found http://forum.xda-developers.com/showthread.php?t=2587543. But aicjofs mentions seeing a bootloader issue once before.
Usually when it hangs at the Nabi logo it means you don't have the USB cable plugged in or that the fastboot driver is not installed.(Check device manager and see if fastboot driver is installed/no exclimation point). If that's not the issue then it's the bootloader which I have only seen one person have that issue. Depending on which OTA's you have ran there was an update to a Jellybean bootloader so it's possible. That can be fixed with nvflash or placing the bootloader blob in the staging partition.
Also you can always get recovery back without fastboot in Android by dd'ing the recovery over.
For example if the recovery image is on the internal SD
dd if=/data/media/recovery.img of=/dev/block/platform/sdhci-tegra.3/by-name/SOS
Click to expand...
Click to collapse
I have NO idea what dd'ing the recover over is...
Thank you for any help fixing this.
P.S. I have a 3rd tablet that I also used TWRP 2.3.3.0 on to root and install gapps with. I did NOT use nabilablite on that tablet to return to stock. Yesturday I used fastboot to flash TWRP 2.6(something) to flash a JB OTA update which worked fine. It was also able to download and install every other OTA update all the way to the most recent KK with no problems...

EDIT: OOOPPS. I didn't see this was in the XDA Assist section. I'm not suppose to answer questions(I was just searching for Nabi questions and didn't notice this was XDA assist), dedicated XDAers just point you in the right direction in this section. Please ask the question again in the Nabi2 section and I'l come help you. http://forum.xda-developers.com/nabi-2
This might help answer some questions http://forum.xda-developers.com/nabi-2/general/nabi-information-t3229119
If it just hangs at fastboot protocol then the USB connection isn't good or fastboot driver isn't installed most of the time. Can you verify fastboot shows up in device manager?(I know the 3rd tabet worked OK) .
Nabilabite doesn't do anything that should change the bootloader, and fastboot should still work as it did before.
dd'ing recovery over means that you use the root access you have in Android to flash the recovery partition instead of using fastboot. IT's just another way of getting the TWRP recovery on the tablet.
The stock recovery won't install the OTA because when you added Gapps it changed some fies and the OTA sees those files as invalid and will fail.
Forced recovery always looks blank screen. It's waiting for you to give it a bootloader to run(beyond the scope here).
You should be able to get back on track once you have TWRP loaded. It's one of 3 things. Bad USB connection, fastboot driver not installed right, bootloader damage. Check the first 2 issues despite the fact the 3rd tablet had no such problems.
One of the XDA smart guys fixed my error of posting this in the wrong section.
I'm running Windows 7 Ultimate and have installed and re-installed the drivers several times. When the tablet's are fully booted ADB has a good connection and sucessfully sends the command to reboot. So I don't believe there is a driver or USB cable error...
When the tablets hang on the fastboot protocol my computer makes the usb connecting noise but fails to install the drivers...
When I hit forced recovery I hear the unrecognized USB device sound...
These two things make me think I don't have the proper drivers installed...but I don't understand how the driver's work when the tablet is booted but not when trying to access the boot loader.
It appears as though I'm going to have to try the dd method if you are able to point me in that direction please.
EDIT: Now I'm thinking I really DON'T have the fastboot drivers installed. I just plugged the 2nd tablet that hands on the fastboot menu and fastboot failed. I also booted the tablet completly, the adb driver's installed correctly but the fastboot driver's did not...I have installed the 64 bit driver's included with nabilablite. I can't find any actual other downloads. The 15 second ADB installer didn't change anything...

Hello, XDA-Members,
long story short, I tried to flash CM-13 on my Honor 5X(KIW-L21 B340). Well, that didn't work and the phone always booted into TWRP. So I flashed FlymeOS because I couldn't flash the stock rom anymore(No matter why.).
It worked perfectly, and I were able to use my phone. After restarting my phone it booted back into TWRP, tried to wipe and all that stuff and even re-flashed Flyme OS, but still booted into TWRP. I was so UPSET that I deciced to flash the original RECOVERY.img for my Honor 5X. Well and from there I made it worse.
Windows and Linux don't recognize my phone. Windows just shows an empty E:\ drive. Reinstalled Google USB drivers, reinstalled driver etc. Didn't work. Now, when I start my phone it boots into the honor 5x recovery. I got these options available:
- Reboot system now
- Wipe data/factory reset
- Wipe cache partition
So, well. I can't install a rom anymore. As well when trying to connect my phone to ADB it won't work either. ADB doesn't recognize my phone. I made a big bull****, tbh. Installed HI-Care as well, but it doesn't get recognized either. I can also boot into Huawei eRecovery, connect to my wifi because it says it can download the stock rom. Guess what, it always said failed so I'm not able to do this either.
I'm really stuck. Anybody got an idea? Thanks in advance!

Shut down the phone
plug the phone into your windows PC
hold volume down + power to enter the bootloader
from windows open the command prompt - type fastboot devices hit enter (your phone serial number will display)
type fastboot flash recovery TWRP.img (be sure to use this TWRP and it's named TWRP.img and in the same folder as fastboot)
after the file is flashed successfully hold power + volume up + volume down
after 5 seconds let go of power and continue to hold the volume buttons until TWRP boots
From TWRP you can now copy the CM13.zip and Gapps.zip to your phone and wipe/factory reset - then install them one by one
be sure their are no errors .. if you see errors choose reboot recovery and try the flash again until it succeeds.
first boot of cm13 will take some time, be patient
Thanks,
I recovered my phone. Awesome!
Somehow I ****ed up my Oneplus One pretty badly.
I can't load in fastboot at all (either with pushing the vol+ key & power key nor with adb reboot-fastboot)
I already flashed the oneplus one recovery tool image and even tried the colouros image.
Nothing worked and I even can't adb push any file on my sdcard nor can I sideload any file to it (error can't find media)
every restart bring me directly to the recovery. (earlier i still had twrp running and tried wiping and flashing zips. even the stockroms didn't work. there was nothing else on the internal space but the gapps/rom zip files)
Isn't there a way I can force a complete image on my phone like I could on my Samsung with odin?
Did i accidently delete my boot partition?
How can I install the fastboot mode?
I will pay via paypal.
Hi folks,
I've got a new A52 5G and wanted it to root. TWRP couldn't be used, because each and every possible solution failed. I even got stuck at boot with a message that the recovery couldn't get startet, even if I just restarted the phone without pressing the keys and without plugged USB cable.
Even flashing the original firmware was not possible. Then I tried to lock the bootloader again and flashing of the firmware was going on with odin. Puh... Then I used the Magisk method without TWRP to change die boot.img with magisk and load it in Odin. Success! I had now root on the phone. Yesterday I read about uninstall Magisk and install it afterwards on the B partition for updating the firmware over OTA. But accidentally I pressed the button below "uninstall" and it performed imediately. Now my phone is dead again... With unlocked Bootloader it is stuck in a bootload and I can start the Samsung recovery mode to wipe the cache for example. I wiped the phone completely, but it is still stucked in a bootloop.
Then I tried my first method: Just lock the Bootloader again (in the download mode) and then flash the new firmware with odin. But Odin either crashes or is giving me instantly the message "failed".
When I'm trying to start the phone (it happened also after locking the bootloader) i'm getting the download screen and the message with a big red !
"partition boot
Reason boot: Hash of data does not match digest in descriptor. [2nd] (3)
Calculated Hash of (boot) : 23B8CFD554, (VEMETA) : D23E59ACD6
CUSTOM boot
VBMETA A526BXXU1AUCA, 38851814R"
Now I unlocked the bootloader again, to access the recovery mode so I can turn it off. Otherwise its stuck in the damn bootloop. Can't flash and wipe doesn't help either.
Please help me somehow -.-
why did you u

why did you OTA update the rooted phone
it is clearly written that your phone might brick.
what happened to you is your boot.img file is replaced with the newer version try replacing with the boot.img file of previous version.
I didn't, because I get (as always, this is not my first rooted phone) the message, that the system has been changed. OTA is not working and I read that uninstall magisk, update the phone and BEFORE reboot install magisk again on partition B. But I accidentaly pressed the second option in magisk, complete uninstall or how its name is. Didn't expected, that its start instantly without a "Caution" message.
Uninstalling Magisk should not bring my phone into a bootloop anyway, even if I wipe the cache. Or am I wrong?

That is the problem how do I do that, when everything with odin stops imediately or odin crashes.
Does Odin give you any error messages? Are you patching all of the files for the firmware AP BL CP & CSC? Are you making sure to use the non home CSC? Have you tried using Samsung Smart Switch to recover your phone?
Smart Switch didn't recognize the phone. The only error on Odin was "succeed 0 / failed 1).
It worked with Windows 10 notebook and the USB C Port. However it didn't worked on Win 7 and regular USB Ports. Very strange. Well, but now I have the original firmware and again lots of bloatware. TWRP doesn't work, impossible to boot with it. How can I root the A52 with Magisk that way, to deactivate it - if needed - for firmware updates? The phone doesn't has A/B partition.
Same happened to me.
So, I have an A52 Indian version and want to flash the Canadian firmware. I downloaded different versions of the Canadian firmware and used Odin to flash. I followed the instructions on downloading the files, loading them into Odin,hit Start and it kept failing. It was giving an error message regarding a repartitioning error. Could this be due to having to tick "OEM Unlocking" in developer options which I hadn't done?
Hey, is your phone still stuck ?
SHAREit​
I tried to root my phone using this guide, followed it down to the word and yet my phone's stuck in a bootloop. It keeps restarting to the Poco start screen.
Ive got the stock recovery, and for some odd reason fastboot commands work only in the "FASTBOOTD" screen and not the the "FASTBOOT" screen which you get from "adb reboot bootloader" command.
I try to shut it down and it boots up back again in the same screen and is stuck there.
Im clueless and I really dont know what to do. Some help would be greatly appreciated.
edit: I tried to use the stock recovery and wipe data. No progress.
I tried to connect the phone with the MIAssistant but the app doesnt recognise the device.
I tried using the MiFlash tool to flash the stock rom, it goes on infinitely. Im currently trying to use the SP Flash tool and MediaTek Bypass tool but I havnt got any progress yet.
I promise I'm never buying MediaTek devices ever again.
Careful with the Flash and Bypass tools, they can cause problems.
What can you achieve with the hardware buttons on the phone? Can you get it into recovery?
Fastbootd working but fastboot not sounds like a USB drivers problem - there are some driver options here.

It was a driver issue, thanks for the link.
What I did to get out of the bootloop:
1. Download the latest Miui rom for your version, make sure it's the recovery version and not the fastboot one.
2. Press ALL the buttons, Vol+ Vol- and Power button to shut it down for a few seconds (assuming you can't switch it off as it keeps powering back up again).
3. After it's switched off, quickly press the power and vol- button until you see the FASTBOOT screen.
4. Connect with PC, make sure you have the proper drivers and have connected with the right USB port.
5. Download OrangeFox custom recovery. It is a unofficial custom recovery, so its stability is questionable. But it does the job here.
6. Copy the OrangeFox zip and the Miui rom file to your phone's SD card or any external storage which your phone can access.
7. In your PC, extract the OrangeFox zip folder in your platform-tools folder. (The folder where you run your cmd fastboot/adb commands)
8. Open up cmd, and enter the command:
fastboot flash boot recovery.img
9. Your phone should boot up to the OrangeFox recovery. If not switch the phone off (Step 2) and press power + vol+ button for booting up to the recovery.
10. Locate your OrangeFox zip installer file in the recovery and flash it.
11. Reboot to the recovery again.
12. Locate the Miui rom and flash that. Before swiping to flash the rom, there is a check box which says something like "flash OrangeFox once the rom has been flashed". If you want to keep OrangeFox as your recovery then check it, or else leave it unchecked. Flashing roms remove custom recoveries.
13. Your phone must reboot to miui.
NOTE: You can use fastboot commands to flash the rom but I'm not very familiar with fastboot commands (I actually forgot most of them). Hence I use the recovery method.
