[Q] n900w8 Won't boot into recovery mode

A few months ago I rooted my N900w8, installed custom recovery (cwm), and flashed Android L. Today I tried to update the recovery, planning on updating the ROM as well. But now no custom recovery works at all, even the one I had running before. When trying to boot into recovery it says booting recovery... like it should, and then the screen just goes blank, then the phone restarts. Sometimes getting stuck in a bootloop trying to boot to recovery, but usually just regularly booting and boots normally to Android L. So now I am unable to update my ROM because not a single custom recovery has worked and therefore I cant flash the .img files. Please Help!

I had the same issue except when I try to load recovery it would "forward" itself to download mode.
This may work for you, try re-flashing the latest CWM update with Odin. Place your phone in download mode by powering it off and holding Volume Down + Home + Power. Press volume up to proceed.
1. Download and extract
2. Run Odin as Administrator (Download if you don't have already)
3. Select CMW file from your download folder and place it in the "AP" section.
4. Start
When finished, Reboot holding Volume UP + Menu + Power Button. Vola!
Let me know if this works for you.

Yeah depending on which recovery I flash it'll either forward to download mode, get stuck in a boot loop trying to start recovery, or restart and load the ROM.
Unfortunately it still isn't working :/ I used the tool from this page (http://forum.xda-developers.com/showthread.php?t=2446269) to convert the .img to a flashable odin file. Used the proper Canadian touch recovery (also tried recovery without touch) from this page (https://www.clockworkmod.com/rommanager) and no luck. Tried to enter recovery mode, it says entering recovery mode, goes black for a few seconds, vibrates then restarts the phone in regular boot mode :/ Any more idea's?
Do I need to be flashing a recovery that supports Android 5.0.2 for it to work? Im so puzzled.

YES!! Finally I was able to get a TWRP 2.8.5.0 working. Downloaded latest version from the main TWRP site and flashed using ODIN, did not use the converting tool above, downloaded the TWRP as a .tar flashable file from their site. Thanks for the help!
Do I need to close this thread or anything? This is my first time posting on xda

Congratulations on solving your own problem! ^_^
I just figured to share my part when i experienced the same issue. I feel like it has somehow corrupt itself after it finished flashing which results in an empty directory for the recovery mode.

dude write some more info will you, i dunno whether
your device is locked
you have developer drivers on your laptop
what TWRP version you are trying to install
but anyways if the whole process is completed without any results consider starting odin as an administrator then flash TWRP

Hello sir
Follow my steps for successful TWRP/ROOT
1.)Download and install Samsung USB Drivers
2.)Download TWRP 3.0.2.0
3.)Download Odin
4.)Download SuperSU.zip file
For download links message me or add me on facebook facebook. com/fRoD.cs
After you complete this 4 steps shutdown your phone and enter into Download Mode
Volume Down + Power + Home
Select continue by Volume Up key
Now connect phone with usb cable into pc and run Odin as administrator
Click on AP box and select the twrp.tar file you download before
Go to Options tab and uncheck Auto Reboot, make sure that only F, Reset Time is checked and click start
After successfully installed TWRP , remove the battery, put it back and make sure that you go into recovery mode immediately!!! Volume Up + Power + Home
If you boot up the phone it will restore the original recovery. Thats why you need to go to recovery mode first.
First time you boot in recovery it will be shown a TWRP screen asking to allow modifications to system partition. Swipe to accept that.
Now select Install option and select SuperSU.zip file. By default it should be in Download folder, and swipe to start install
After installing click reboot and your SM-G361F will be rooted. You should have SuperSU app in the menu

Ah, opportunely, I have the exact same device.
Now, I have actually installed TWRP before so I can help.
Usually, if it stops the flashing process, it may be a case of the Custom binary being blocked by the FRP lock on the device. Have you OEM unlocked it?
On the device, when you boot it into download mode, does it say FRP LOCK: ON on the screen?
If not, skip this step.
If so, you need to do the following:
1) Reboot the device normally
2) Go into Settings, Developer Options (note: to enable it, go to About Device and spam the Build Number box until it says that you are a developer)
3) Find where it says 'OEM Unlock'
4) Confirm the change
Now, there is an extra step which I had to take if you have a Google account signed in on your device. You might not need to, but it's best just in case:
1) Go to Settings, Accounts and Google
2) Click the Google account on the device
3) Click 'Remove Account' and confirm
Note: You will need to sign in to use any of the GApps, but you cannot access the recovery whilst being signed in because of the FRP lock.
4) Reboot your device into download mode and try again.
This may not be the case, though.
Also, don't bother with adding that guy on Facebook. I have all the downloadable things you need here, but I advise you do follow his guide, except the Download folder section. He missed out that you need to download the SuperSU binary to your device. Downloads are here:
Here are the Samsung USB Drivers for Mobile Phones (NOTE: You may not need these at all since you can actually begin the flashing process without them, so don't bother):
http://developer.samsung.com/galaxy/others/android-usb-driver-for-windows
Here is the TWRP recovery (NOTE: Please download the 3.0.2.0 version, since it is more up-to-date and more likely to succeed:
https://forum.xda-developers.com/ga...sm-g361f-unofficial-twrp-2-8-7-3-0-2-t3425402
And here is ODIN (You already have it, but here it is anyway. Also, download the first one, not the second one, since the first one is newer):
https://odindownload.com/download/
Also, the SuperSU binary (Note: It's easier to open it in your Android browser and download the file from there. That avoids the need to transfer the file from the PC to the phone):
http://www.supersu.com/download
Now, it could, in fact, be a problem with the USB cable. It's highly unlikely, but mine is a bit tempermental, insisting that if I nudge it, it'll stop working.
Notify me how it goes, because this worked first time for me.

Go to developer settings and check OEM Unlocking (if its already checked recheck it) and then reboot. Then close the phone and install TWRP.

Hi I've managed to install the correct twrp on my device but when I go into recovery I get the same message not seandroid enforcing. I've followed all the steps but I can't get it into recovery on twrp. Does anyone have a solution please?

Flashing S7E Exynos - Used Odin + TWRP, can't get any further.

Hi everyone, I tried to use this guide to root my phone.
Can confirm it's International, so Exynos.
Used Odin 3.12 and TWRP image 3.1.1 for hero2lte, which is the correct version.
Everything flashed perfectly - Got the OK from Odin, so can't see any problems that side.
Now the problem I'm getting:
When booting into recovery, I get installing updates... then 'No command' screen, like in this thread
I have factory reset via the recovery I DO have (I don't think this is TWRP, there's no touch interface, and it's all controlled via volume + power keys). This allows me to boot into the OS.
I have the option to boot into bootloader, and this takes a little while to do, but seems to fail and boot into the OS anyway.
I have no way of trying to reflash TWRP that I'm aware of, and I'm kinda stuck... could anyone help me from this point on please? Thank you!
EDIT: I'm trying to install custom ROMs and tweaks (Not sure if things like busybox/gravitybox/xPosed framework etc. exist anymore - haven't touched custom stuff for 3 years now! If you know, please let me know too!) So are there OTHER steps I should be aware of/know if I wanna proceed?

(just posting reply so I can see this thread later on, gonna do the same thing after exams, if I get same issue, this will be helpful)
P.S: By the way, when flashing TWRP, deselect auto reboot and see if you can go to recovery without booting it first. Sorry can't think of more options :S

after disabled auto reboot, then holding vol up and home and boot it booted to twrp.

Flash each of the checkboxes individually or it will send you back to download mode
Only one checkbox at a time also make sure ur oem unlock is enabled

Samsung J7 Pro Soft Brick after Oreo 8.1 update (no root)

Hi everyone...
Two days ago, and a few hours after installing the 8.1 update, my mom's J7 touchscreen was unresponsive, including the power button. It ran out of battery, and after I restarted it this morning, it goes to recovery mode after it tries installing system update and the No command screen is displayed.
I've searched on the web for hours and hours for solutions but none of them have worked, most probably because it requires the phone to be connected to the PC, and my PC (Windows 10) isn't even seeing the phone via USB (can't use ODIN nor ADB). BTW, the debug option most probably wasn't turned on prior to soft brick.
Phone Info:
SM-J730G J730GDXS5BRK1
No root
Error on recovery screen (the SD card has been taken out):
======================================
#fail to open recovery_cause(No such file or directory)#
#Reboot Recovery Cause is [UNKNOWN]#
No Support SINGLE-SKU
File-Based OTA
Supported API: 3
E:unknown volume for path [/odm]
E:unknown volume for path [/vendor]
E:unknown volume for path [/odm]
E:unknown volume for path [/vendor]
# MANUAL MODE v1.0.0#
Successfully verified dmverity hash tree
=======================================
Additional info: As I've mentioned, the power button isn't responsive, so I press the volume down button to choose the recovery options. I've tried all recovery options except for:
Wipe data / factory reset, as the phone data isn't backed up (mom doesn't want to lose the personal data as much as possible)
Apply update from ADB
Apply update from SD card
All other options are looping back to the recovery screen after installing system update screen.
Lastly, in recovery, there's an option at the bottom that states "Lacking storage booting". I'm sure that would mean something to someone reading this that would help solve the issue.
An OS downgrade or same 8.1 fix is preferred, as long as the phone data is intact. Any and all help would be much appreciated.

Try "Emergency Software Recovery" feature in Samsung Smart Switch for PC.
It could be a hardware issue as well. Clean your USB charging port with a brush and a drop of alcohol. Then dry with a hair drier.

Good evening, have you tried installing the latest version of the firmware by odin?
If not, try this.
probably its touch stopped working after the update because it was not original (already it has been changed) or it can be other cases ..
if you still can not install the newest firmware downloaded from the sammobile site you can do the second procedure.
Such you will find in this same forum.
In it you use the pc miracle box application and downgrade to 7.1.
this is the title of the post.
follow all procedures.
and it will be all right.

PS: Putting it into download mode: Turn the device on by holding the volume down buttons + Home + Power

Thank you. I've tried 3 times now as I am getting stuck at II. Flash TWRP and fix rom. After I flash the nougat rom via TWRP, phone reboots and the logos keep on looping. Either I am doing something wrong or I'm missing a step, or the zip is not working for my mom's phone.

Then when you get to step II open the twrp and go into settings and uncheck the prompt option to install supersu if it is checked. whenever you do something in twrp uncheck this option. I do not know if this will be your problem but this always happens to me, if not clear at the time of restart the cell phone is in the loop screen exactly because of this option.

Checked TWRP Settings and there's no option / tickbox for supersu. I think one thing that I'm doing wrong is that I'm formatting data in TWRP during the wipe process instead of just sliding it to restore factory settings. I will try again later today after work.
Also, one thing I've noticed after flashing TWRP is that I have to enter recovery mode twice - the first time, it goes to the No command error screen then goes to stock recovery. Only after a reboot in the stock recovery would the phone enter TWRP recovery.

Just one more thing. In tutorials on how to install twrp. when you enter twrp the first thing you should do is format the data. then install the rmm state prenormal and bypass files and only then install magisk or a custom rom.

Before trying to flash TWRP, first flash a full stock firmware and make sure your can at least boot all the way up to the main screen.
Once that works, only then try to flash any custom recovery or custom rom.

Same prob
I've just faced the same problem a few days after my update as well. Did you figure out how to get it back to normal? Thank you!

[solved!] Used ODIN to install twrp but phone won't boot into recovery at all

Problem solved! i was installing the wrong version of twrp this is the correct version: https://eu.dl.twrp.me/j5xnlte/
I'm using SM-J510H
So I installed samsung drivers.
I even installed ADB and it's drivers (now i have samsung android in the device manager)
I downloaded TWRP for j53gxx:
https://eu.dl.twrp.me/j53gxx/
The .tar for odin (twrp-3.4.0-0-j53gxx.img.tar)
I did the OEM unlock and debugging thing I even got the notification that the computer was trying to access blah blah I did allow always.
Put the phone in download mode (Down + Home + Power)
Press up to enter download mode.
Connect the phone.
Untick reboot in odin.
Use the ap to select the correct file
Start success!
I try to reload into recovery tried so many different ways even the adb command to reboot into recovery. All I get is a little thing on the top left saying warranty bit recovery and then the screen is black.
It doesn't load into the default recovery it just stays black. I need to take the battery to rest...
I tried with adb but when i force it to load up into download mode (adb reboot bootloader)
adb doesn't recognize the phone anymore
I've now downloaded the android ask maybe that will solve things lol but does anyone have any advice please?

Should I consider installing a different recovery? like maybe CWM?
It has a costume rom on i guess it says "Hebrew by daniel mouyal for bt" in the about tab in the settings...
I tried using ADB to install but when it's in download mod it can't find the phone so when i enter the install command:"fastboot flash recovery twrp-2.8.x.x-xxx.img" it says: "waiting for device"
Well I've been installing the wrong version of twrp lol sry!
So just in case someone else hits the same problem it's not the twrp i posted before but this one:
https://eu.dl.twrp.me/j5xnlte/

When recovery is finished flashing in Odin, remove your battery to turn the device off.
Then put the battery back in and press vol+ and power button and home button at the same time.
Your device should then boot into twrp.
If you reboot before doing this the android operating system will ovewrite twrp with stock recovery and you will have to start the process again
Also you used the wrong twrp. J53gxx is 2015 model j500h and j5xnlte is j510fn not j510h. You must be careful or else you may seriously damage your device.
Use this twrp here for your device j510h

Thank you for the response!
I managed to figure out the issue it was the wrong twrp version.. I can't update the title though

That's no problem.
What I would suggest though is to post how you fixed your issue in case anyone has problems in the future they can be referred to your thread here
