Not able to get into TWRP recovery, stuck on "Your device is booting now..."

Not able to get into TWRP recovery, stuck on "Your device is booting now..."
Hey everyone,
I just unlocked my bootloader and now want to flash TWRP and SuperSU. My Phone is already Nougat with Emui 5.
The Problem is that I'm just not able to enter the recovery. When pressing volume down + power or trying "adb reboot recovery" in the command line, the phone starts in the "unlocked bootloader warning screen". But not like in the normal warning screen it doesn't give me options but just shows a white line saying "Your device is booting now..." and thats where it gets stuck. Only gets hotter...
The fun thing is I already was in the recovery but wasn't able to flash the SuperSU (r275). Maybe it was not compatible with Nougat. TWRP just couldn't mount various things. After reflashing the recovery below instead of some other version (don't know anymore) I'm not able to enter the recovery again.
Feels like I searched the whole Internet and there is nearly nobody with the problem or a solution. Tried this as well: https://forum.xda-developers.com/honor-8/help/honor-8-boot-to-twrp-recovery-lost-root-t3567462. It seems like nobody who published a Honor 8 + Nougat + TWRP + SuperSU "How To" acutally tried it himself.
I used this TWRP https://forum.xda-developers.com/honor-8/development/twrp-t3566563
Please help me I can't use WhatsApp because I need to restore it with Titanium (Database way doesn't restore all chats... Other problem)
Thanks everybody I just can't stand this anymore

I had this issue after downgrading to EMUI 4.1 and upgrading to 5.0 again via twrp. I flashed some old 3.0.2.0 version from another developer. Booted into that, flashed the update.zip package for emui 5.0 and then i was able to successfully flash and boot into 3.1.1.0

Thank you I got it!
So I got my L09 with Nougat/Emui 5 on it. Then just used TWRP from https://forum.xda-developers.com/showpost.php?p=70228949&postcount=252 (bootable, think ist ist 3.0.2.0) then flashed 3.1.1.0 from https://forum.xda-developers.com/honor-8/development/twrp-t3566563 (bootable) and finally flashed SuperSu from first Link again. Other SuperSU versions (like the phh r275) WERE NOT flashable.

Magisk is the most compatible root solution for the Honor 8 on Nougat. The only thing that doesn't work (seamlessly) is MagiskHide, but the root itself works and flashes fine from TWRP.

I have tried to flash twrp multiple times to no success. I have tried multiple variations of the tool but for some reason when I go try to boot into recovery it takes me to erecovery which fails to do anything.

Are you sure about button combination

If you're trying to boot in to recovery with your phone plugged in to the computer it will także you to erecovery. If only i could find the person who całe up with this stupid idea that caused me hours of struggles, they'd pay for it. also when you use the pwr + vol.down combination let go off the power when you feel the vibration and further hold the vol.down until you see the boot screen appear.

I tried this like 20 times but this time it worked! I know have TWRP working. weird think tho is that no keyboard or default Huawei apps are preinstalled and BT isn't working.

Few problems with Binary SU and BusyBox
My phone seems to be rooted. Titanium Backup works but I have to accept every App instalation manually. With other settings restoring gets stuck. Also SuperSU reminds me every time that my BinarySU needs an actualisation but fails if it tries. And finally BusyBox just isn't able to get itself installed.
I'm thinking about restoring stock firmware, update to Nougat, and flash the two TWRP Versions and SuperSU again but hate to spend ours on my phone. OnePlus One rooting was sooo easy...

Is there a number of times you have to do it? How should I transition from this stupid "Your device is an enemy of the state" screen to something that will connect to adb?

J4 plus (J415GB) bricked

Is there anyone here facing same with my situation? today i bricked my J4 plus, Dunno if its hard bricked or soft brick, I can't enter to download mode and system restore anymore. Im just trying to get oreo back because i fell little laggy on my current os (pie). I went to samsung service center and they told to use JTAG to get it fix but its too expensive for me to pay hundreds buck for this.
Thank you

its not bricked. your battery is full drained. i had the same problem and how i fixed!!! i presed all 3 buttons and put usb cable to my pc and my phone. it goes like bootloop starts and shuts. you will wait with pressed buttons from 5 to 10 mins depend how low is your battery. and finaly will go to download mode and you can flash it then!!!

Bricked my J4+
Can someone help me with a bricked J4+?
I wanted to install TWRP, I followed the guide to the letter on how to install TWRP.
After successfully flashing TWRP 3.2.3-0 and flashing RMM bypass zip (without booting to the OS) I also performed a Wipe Cache in TWRP.
I booted to the Samsung OS and the system overall felt laggy.
I performed a Factory Reset, still the system felt laggy.
I decided to use Odin and install the Samsung factory system (thus go back to Samsung OS).
I booted successfully and decided to give TWRP 3.2.3-0 another chance.
Odin resulted in FAIL when trying to flash with the following error: Can't open the specified file (line: 1892)
I tried different versions of Odin (from last to previous ones), different USB ports, I even tried another PC but no success.
I performed another factory reset and now the phone is hard bricked I guess because it will power on...try to get in stock recovery and Erase...and then power off. I can't get to download mode or stock recovery.
Any help I would highly appreciate it.
Thanks.

The part where I had to format the data...I have missed that. Thanks for pointing it out.
I took the phone to a repair shop because it is hard bricked and it needs jtag to unbrick it.
As soon as I have it back I will try again to install TWRP.
Thanks for the help, I appreciate it.

This is a phone from work and I did toggle EOM unlock and USB debugging in order to flash TWRP.
I did not enter any password, face unlock, pattern or sign in to google....nothing of the sort. As soon as I opened the phone from the box tried to install TWRP knowing it will erase everything after TWRP installation. I really hate Samsung UI and wanted to try Lineage OS or another custom ROM which is not laggy like ONE UI.
After installing TWRP the phone became very laggy (obviously I did not perform a format data...my bad) I did use Odin and flashed the corresponding firmware of the phone and it did that successfully.
I tried to give TWRP another shot by flashing it again but I was getting a FAIL in Odin with the following error: Can't open the specified file (line: 1892)
After this I tried to flash again the same Samsung firmware but kept getting the same FAIL and the same error: Can't open the specified file (line: 1892)
I have tried all versions of Odin but the same FAIL and same error.
Now I can't even get into Download mode or Samsung recovery mode.
I press Volume Up + Volume Down and insert the micro USB cable....the phone takes at least 10 seconds to power up (Samsung logo) and then I see a blue screen with Android robot trying to perform an Erase and then fails and the phone powers off immediately.
As soon as I get the phone I will check your link on XDA and try a GSI ROM.
Which one do you recommend...this is a work phone, all I care about is speed and fluidity and it has to be a daily driver.

yeeeahhh. i am knowing that in hard way. you can check user data only if you have ORIGINAL firmware and not rooted phone(mean twrp),if you have rooted(twrp) then flash with or without user data. some firmwares on web can flash with user data, some cant.anyway as i say you can always ask for help.i will gladly help if i can. good luck.

What you're describing are symptoms of a flat battery and a direct boot to recovery.
To boot to download mode plug in the USB cable first then hold vol up, vol down and power until download mode appears.
There is absolutely no way TWRP caused the lag. TWRP runs in its own minimal OS environment and has no effect on a booted android OS whatsoever.
Lastly your device wasn't hard bricked, a device that powers on even if it doesn't boot is only soft bricked.
Usually recoverable using the right procedure.

I managed to boot into the Revovery and perform a factory reset, now the phone booted normally.
I will try and install TWRP.
When these strange things happened the device had over 80% battery...at least that's what it showed on screen.
Now I see that indeed it was flat 0% and you were right to point out that this is a flat battery problem.
Thanks for the help I really appreciate it.

Boot to Samsung OS.
Is this procedure correct?
Thanks.

It's correct, but if you want access to the data partition in twrp you need to also install the encryption patch.
You will also need to either install magisk or some other patch that disables dmverity.

Stuck at TWRP Loop!

My phone got stuck at TWRP Loop!!
So, there is what i did...
I flashed Samsung a7 firmware ANDROID 10 [download from firja] and it worked. I needed to root my phone and tried Magisk new app.
But, with new Firmware I did not had TWRP installed, so I flashed TWRP with oden as instructed in this POST [BTW, I followed first method , not the *****OREO ROOT INSTRUCTIONS:***** ].
** TWRP version is 3.2.3-1_ashyx **
After that my phone got stuck at TWRP Loop.
Phone will not boot to normal , only BOOTLOOP to TWRP. Most of the time TWRP doesn't load fully and TWRP screen seams Black Line [in horizontal axix, MY phone display fine, it seems come from The TWRP!! ].
So, I am kinda STUCK at this TWRP Loop and TWRP load at it LOGO nothing more.
I tried every possible KEY combination to get to the fastboot mode/download mode but failed.
One or TWO time I was able[or it did it self!] to boot into TWRP (TWRP loaded but , with BLACK line) , i tried to enter download mode but failed.
So, what can i do?
-Thanks

I got the same problem, i did this: Power + volume down next when it restarted fast pressed v+ and v- and plug in the cable before it showed samsung logo

Nothing to worry and don't panic,
I've been facing problem like this.
To enter bootloader / download mode. With USB Cable plugged You must press and hold Power + Vol Down button then count it for 7-8 seconds, after that immediately release Power button, and press Vol Up + Down. Repeat this step if fail. U will see Download mode.
Regards.

You hold volume down + power button for 7 seconds and phone will be power off.
Then you press both volume buttons (vol up + vol down) and plug in cable what is connected to computer, this pusch you to download mode of phone.

exactly this is the thing I missing the Fastboot mode to...

Hi, Bennie from Holland here, with the same problem: tried to flash Twrp to the Samsung A750FN and now stuck in not working Twrp logo, flashing for 2 seconds and further a black screen< The fastboot using Odin can be used via the method described by szimin22, bur the adb fastboot gives no response. Does someone know the correct trwp version for this mobile or a firmware file that can be flashed by Odin?

A Week Later ...
i have installed on the a7 the firmware dated okt 2020 and i can install without any prob trwrp or PBRP! but the machine goes into bootloop again. The only thing which seems to be resolved is a normal functional recovery. Now the return to the phone itself and we are home! any suggestions, pls give us a chance to not smash the a7 through the kitchenwindow

From lineage recovery to TWRP recovery.

Hi everyone!
First I am not so versed in the flashing game, so bear with my incompetence please.
I recently tried to update my note 3 on lineageos 15 to 18.1, however, doing so, unbeknownst to me, TWRP was replaced by lineageos recovery. Now I have 18.1 and I want to install the gapps, but to do so, I was told I needed to wipe 3 things, dalvik an two other things, ... anyway, I can't do anything now that I have lineage recovery. To get TWRP, I tried to follow this precedure : https://www.droidwin.com/replace-lineageos-recovery-with-twrp/ but in vain. I get stuck at Step 2. point 3, where my phone goes into ODIN MODE with a droid saying downloading, do not turn off. and nothing gives then. Do you have any idea of something I can do to get TWRP back?

Samsung devices don't use fastboot to interact with the bootloader, instead they use something called Download Mode and a tool called ODIN. You need that tool installed to flash anything on the bootloader level. Proper instruction for your device can be found HERE.
Also as a side note, Your device has a unique boot sequence. Your device's Boot partition (also called ramdisk) houses part of the recovery and the Bootloader will try to overwrite it with the ROM's pre-bundeled Recovery as soon as it boots up. There are ways around that such as:
Your ROM should pre-bundle TWRP as a recovery (LOS has opted to include their own).
You patch the boot partiton as soon as you change it, meaning you have to boot straight to TWRP using key combination after flashing using ODIN so it does that for you.
So don't get frustrated if it doesn't stick and try again.

Awesome!! I had to get other instructions for using odin, the missing part in the link you gave me was "push AP and get the .tar from here and click start" other than that, I did what you said, (missed the first time, got lineage recovery instead of twrp, did it again by removing the battery after it booted from odin, and did the volume up + home + power) and I got TWRP back ! Wohoo!!
Thanks a lot.
And to whomever working on lineageOS reading this, please consider leaving the recovery part to Team Win, there is no point for us users to have a recovery with no wipe so no updating a ROM, as far as I understand the process... but what do I know...

Ok I now installed mindthegapps, and my phone goes to download mode when it reboots. so... do I have to re-instal the lineageOS rom after or before the gapps?

Ok I got it somehow! thanks.

Question No Download Mode - bricked S21+

Hi,
I've managed to brick my S21+, after a mistake during flashing of a newer twrp version with Odin.
I basically placed the (patched) stock AP file in the AP slot instead of the TWRP tar, and the vbmeta_disabled_R.tar in the userdata slot.
After reboot, I got a boot loop, and I am not able to boot to recovery or to download mode as before when using the key-combo.
Previous to this flashing, I had the TWRP 3.6 and Lineageos 19 GSI for about 6 months, with no issues.
My question - how can I get to Download mode now? and is it possible that I ran over my recovery?
Is it possible that the download mode is no longer available due to the AP flashing (no BL, CSC files)?
Appreciate any suggestion and help!

connect it to the PC and do the combination that you did before, that is volume up and volume down pressed at the same time, that same thing happened to me, when I wanted to update twrp better install the stock first and then the new recovery, so you take advantage of updating the firmware of the phone and the new recovery

Strangely, the recovery entry or download does not work without being connected, so I recommend you better install the magisk to enter the recovery from there, otherwise you will have to do that process when you want to update or install custom roms

Thanks for your reply!
the key-combo in S21x are with USB plugged to PC, otherwise recovery cannot be reached, unless using ADB command. I have tried this many times since the wrong Odin flash occurred, but nothing happens except from reboot, warning screen (about unofficial software) and reboot again.
Even previous to the bricking, typically in order to get to download mode in this device, you need to go through recovery first and then select download mode. Alternatively, adb reboot download command, but neither are now an option.
So my last resort was a USB-JIG device to get to download mode - but I don't know of any such device for a USB-C connection.
Anyone here has experience with that? or can direct me to such a device for the newer Samsung models?
Thanks!

Thanks for your help! - indeed the PLUS and MINUS volume keys with the usb cable plugged in gets you directly to d/l mode. I just tried it with the power key all the time, as in previous models, and that got me nothing.
Issue solved!
