"Bricked" Note 8, can't boot into TWRP - Samsung Galaxy Note 8 Questions and Answers

So I tried to mod my phone (with this, if you're interested https://forum.xda-developers.com/gal...creen-t3759567) but I did something stupid. I thought TWRP was working properly but I'd installed Oreo and didn't wipe data. Well I installed the zip anyway. At the end, an error showed up (could not mount /data or something similar) and my phone will now not boot.
If I try to boot the phone, it just vibrates and stays black. Volume Down + Power + Bixby gets the phone out of this state and the charging screen shows again. I can't boot into TWRP at all. I can boot into download mode but Odin keeps failing when I try to reflash the XEF Oreo firmware (screenshot is in the attachment, it says passed but doesn't attempt to flash the files). I managed to flash TWRP which worked but since I can't boot into it it didn't help. Anthing else I can flash with Odin, or can anybody tell me what's going on / if it's unrecoverable? (I've tried a couple of different versions, they all exhibit the same behaviour)

There is a newer version of odin, are you using that? You will need that to flash Oreo. Can get it in the link below. Odin v3.13.1

Doh! Had it already, was the only one I didn't try. It's flashing now. Many thanks

N900A NC2 Wont boot, missing recovery

Hey guys I got a AT&T Note 3 that wont boot. When i try it turn it on it gets stuck, so i tried to do a hard reset on it, but every time it tries to boot into recovery it restarts itself, so i though it must be missing a recovery, so I loaded the full NC2 software on it via ODIN, everything passed without issues. But on the first boot it tries to boot into recovery again which i think is normal after a full odin flash, the recovery is still missing. I found the master thread for all the stock recoveries, but the NC2 recovery is a bad link. Does anyone have a stock NC2 recovery i can try? Or does anyone konw whats wrong with it?
thanks

Did you use these Odin files? http://forum.xda-developers.com/showpost.php?p=54803130&postcount=136 If you did the All-In-One, you know it will not wipe your phone. I always do the four files and have no problems and it's normal to see the recovery to boot.
Yes
I have tried both, all in 1 and 1 in each. After it says complete when it boots it says recovery booting, then it turns off and turns back on and recovery booting, then off and on again non stop.

Can't enter recovery- GT-I9295 strange behaviour

Hey guys,
i'm in trouble installing a custom ROM on a S4 Active (GT-I9295, Baseband IXXUDOB4, 5.0.1).
Flashed CF--Autoroot with Odin, no problem.
Then i flashed TWRP, Odin showed its green "PASS!"-message but i can't boot into recovery.
I'm well aware of the timing issue when doing the first reboot into a custom recovery, and i assure you this isn't the problem.
I tried countless times, after a while i installed ROM manager to try if i could flash the ROM file that way.
It installed another custom recovery -CWM- on top, and also showed up the TWRP recovery:
http://imgur.com/kSSiuld
Still, booting into any recovery does not work, neither from ROM managers menu or via any button-press combination.
When pressing vol up+home+power, the phone shows the blue "revovery loading"-line AND the red line *****ing about the root, but continues to boot as if it had been switched on normally.
I even looked for the ominous "install-sh" script in system/etc to understand why nothing gets me into recovery-
what the heck can this be?!
Did the same thing to S6 and S5 without any hassle, i'm stuck with this for several days now and i am running out of ideas.
Anyone...?
Not a very technical answer, but have you tried pulling the battery out for 30 seconds and trying again?
Yes we did, unfortunately, this also didn`t help.
Tried loads of things actually, still impossible to access that damn recovery

HELP!! Le2 x526 Not booting Up, nor Charging

Hello Friends,
Yesterday I was chatting on whatsapp and suddenly my le2 restarts, and then a blue splash screen appears and device keeps on booting,
hence I went to recovery and clear the data, but that also didnt help me,
Then i flash the 13s rom via Flashone 1.9 then also same problem happens, sometimes it went to optimizing apps 3 of 4 and again restarts with blue LED, i were unable to switch it off,
after draining the whole battery I keep mobile to charge but now it is not charging, it only showing Red Solid LED Continuously.
Now I am also Unable to boot into recovery or fastboot mode.
I again flash the stock 13s rom via flashone 1.9 , i got success msg but then also mobile is not booting nor it is charging.
Note: I am on complete stock rom on locked bootloader, never unlocked or rooted, used as come in box.
Please give me a solution on this, I have searched everywhere but not getting any solutions.
Thanks in advance
Try to check your USB cable, most of the time charging issue is due to cable

Cable is ok. I have another Le2 and it is charging with that cable very well
I am facing same problem. How you solve this issue? Blue led blinks after flashing any rom and bootloop.

I also have the exact same problem. Phone started rebooting as soon as it booted up. Somehow i managed to unlock the bootloader, but to no avail. Can't seems to find any rom which can boot up. So practically i have a bricked device with trwp. Formatted the system and other partitions with twrp, flashed many roms. Still the result is same. Bootloops.
Hi,
try to to reimage your phone with QFIL from this site:
https://www.techpoison.in/2017/12/how-to-flash-letv-le-2-x526-stock.html
I downloaded everything from there, QFIL, Sparse image and drivers. My phone was bricked, but its working normally now. After you flash the image your phone should charge normally, just try to boot it up. In my case i had issues with baseband, not detected, no sim function and no wifi and phone was restarting each 3-4 minutes, but it was operable. Basedband issues can be solved by hard reseting the phone and updating it to 21s using the local update, just put the 21s stock renamed to update.zip to internal storage and run system update. When you get the error - APK missing, just boot it up again and retry the local update, should work fine the second time, i just deleted the update.zip and put back again and ran the update.

Flash the 21s bootloader + modem, one ZIP file, should work fine. Not sure what ROM did you install last time. You can give it a shot with with MIUI 10 - its nougat.
I had similar issues, see my topic, maybe it helps a bit.

Brother same thing happened to me, a week ago. I cant say about your problem but my problem was due to faulty power button. Actually due to that reason my phone actually kept restarting itself. It showed red light blinking while charging and wasn't able to bypass the optimizing app screen. I also thought it was a software issue but actually it wasn't. I spent about 2 hours figuring out what the actual problem was. The problem was: As we know when power button is hard pressed for about 10-15 seconds it reboots itself.
Although the repair shop guy didn't put new power button but he added a tiny piece of paper in between the power button and body housing to prevent the issue and voila the problem was solved.

Hi, Thanks. I actually did that first, flashing through qfil the same rom. it helped me to go to settings after umpteen attempts to go past language selection screen, and i was just able to oem unlock and enable usb debugging (actually after a 2nd partial failed flashing). the phone kept freezing within seconds of booting up. Now After i unlocked the bootloader and installing twrp and flashing many roms thru twrp, i am still having the same problem of booting up and freezing at start-up. cant flash again through qfil, as i will again loose the unlocked bootloader and twrp.
At least , now i can try different roms to see which can unbrick it. last one used was the twrp flashable rom based on eui (small eui by aurel) but it also freezes on language selection screen or beyond.
I am running out of ideas, lets see.
2nd partial failed flashing? any issues during the flash process? i had some issues when i used usb 3.0, 2.0 worked fine for me. If you have also charging issues stay in twrp and let the phone charge properly, its slower but should work fine. You can try to flash the 21s bootloader with modem, maybe it will boot properly. But try it only when you are able to enter the fastboot mode, longpress volume down and power for 10-15 seconds, if that is working you should be able to flash twrp via fastboot and you can experiment a bit. Try to find the chinesse twrp 3.0.2.0 and try to flash the stock 21s version. Should be also an image file, in standard twrp go to install - image, after selecting the image file click on recovery and install, after installation go back, reboot, recovery. Copy 21s to storage, wipe data, cache, dalvik and flash it, chinesse twrp will skip version check and will let you install the stock image, after install reboot but click on do not replace recovery button - this will keep the chinesse twrp installed.
If nothing helps it can be only a HW failure, maybe the power button, try usb 2.0 port during the flash process, i had issues with 3.0 on my pc, if that doesnt help.try a different cable, no more suggestions, sorry.

My phone has been flashed multiple times by qfil method. And always it hangs at initial setup (so it boots up, but hangs at language selection or further up screens, before setup can complete and launcher could be loaded).
While trying to flash again with qfil once it stopped at 25 percent (because the battery went dead). Charged the battery and booted up the phone, and i was surprised it booted up. After 2-3 attempts i was able to reach the launcher screen and immediately enabled developer options and oem unlock / usb debugging. Only had few split seconds to do this and the phone froze again. After that i installed twrp and hence treying different roms. Most fail at setup.
Just tried MIUI 9PRO ROM. It also froze at setup multiple times, but once i was able to complete the setup and miui launcher is up , but it reboots or turn off the phone just after that. So cant do anything with the phone. Unsure of whether a newer bootloader will help in these freezing issues as i have been able to boot up at least in some roms only if for few seconds. Will try to tinker the settings of miui rom (if the phone let me do it before freezing/hanging). Lets see. Thanks for suggestions. More suggestions welcome, because i am still unsure weather this is a software or hardware related problem. I am guessing that it may have something to do with Google security as earlier i was getting msg that phone has been wrongly resetted and needs to verify with Google (but i couldn't get a chance to use the same account, as phone kept freezing at setup).
Did you fully charge the battery, if not let it fully charge in twrp. Flashing the roms in twrp works everytime or do you see any errors? Before you flash anything disconnect the usb cable.
---------- Post added at 09:54 PM ---------- Previous post was at 09:47 PM ----------
Try to flash the 21s bootloarder with modem, one zip using twrp. Go to fastboot mode and wipe modems. fastboot erase modem1st fastboot erase modem2st. Put the phone to flash mode and reimage with qfil. Before you do it write down both imeis, you can find them also on the original package on the backside. Also try to remove all sim cards from the phone and try a different cable. If nothing helps, hw issue, maybe the power button mention earlier in this thread.
After reflash skip everything at setup and reset phone to factory defaults. OEM is already unlocked, you dont have to do it again.
I have charged the phone fully before any flashing after that error. I can flash the phone through twrp without any error msg. The phone boots up most of times in various roms but hangs at or after the initial setup screens show (like language selection etc). Flashed the modem+bootloader, success, but it showed bootloader version as 20s (not 21s). Tried the commands u mentioned to erase modems, it say error failed, no such partition found. I had checked the partitions with parted and 56 partitions are there including the modemst1 & 2.
Now re flashed via qfil , did as advised but again the same problem of hanging / freezing at or after initialization screens of various roms.

Yeah sorry i screwed the command its fastboot erase modest1 modemst2, my bad.
Just now i was able to complete the initialization (setup screen) of sparse image india rom. I can reach the launcher and settings for few seconds before the device freezes or reboots.
So the same problem , with which i started, the only good thing is that i have been able to set oem unlock to on, so that i can flash trwp and various roms (but all fail with the same freezing issues)

So you erased modems and reflashed with qfil right? If so i assume its a HW problem. Try the fix with the power button, i ran out of ideas
Last thing which can help maybe: https://www.youtube.com/watch?v=LH3VOIlLfvo&t=135s
Download 21s stock image + the chinesse twrp, links should be under the video, i think so, or look somewhere in the forum for new links. Try to reflash the 21s, some people reported that freezing issues were gone after installing the latest EUI. Basically you can do the same after QFIL reflash but you need enough time to copy the ZIP file as UPDATE.ZIP to the internal storage and run the local update via setting, system update and local update, i hope that TWRP will work for you, just follow the video tutorial.

Did that also, the same problem. The phone freezes after the os is booted. I was wondering what is that isnt touched by flashing ( in download mode or fastboot mode or through twrp). I may need to tinker that. The roms are all fine in the sense they all stop at the same points. Something in the phones partition, which isnt touched by flashing? (There must be, as i flashed with qfil, the oem unlock remains, the bootloader didn't lock, and it remains unaffected by re-imaging)
Try this, maybe it helps:

How to recover from Verification Failed, Bootloops, and Android/Carrier logo freeze.

In this tutorial I will inform you on three different soft bricks, and how to fix them.
You must be able to boot into TWRP and/or Odin/Download mode!​
1.) Verification Failed.
Method #1
This method will work with people whom can't reset their device, due to an unmountable /data partition, and those whom experience this error, who can reset but have valuable items, applications, videos, or photos that they don't want to lose. Must be able to boot into Odin/Download mode. (Volume Down+Home+Power)
The solution is actually pretty simple. Boot into Odin/Download mode. This has to be done correctly, not from TWRP recovery. When the prompt for "Volume Up = Continue" and "Volume Down = Cancel (Restart)" press volume down. You should no longer see verification failed, but instead be sitting on the T-Mobile logo. This is normal, and could take 30 seconds to 10 minutes, depending on the amount of data.
This method works all because of Knox. Knox is what Samsung uses to void your warranty. Companies are not allowed to void a warranty when rooting, installing roms, or recovery, unless they have direct evidence. Knox will trigger this when it isn't sure. It will try forcing you to bring it to Samsung, and they can directly find out why it was caused. This happens when it thinks that you cancelled.
Method #2
This one will require you to lose all your data, but is mainly intended for those whom cannot reset their device. Download the stock firmware from the links below. Open Odin (Jodin3 will not work! It is not fully functioning, do not try it.) and boot device into Download/Odin mode. On your computer, you should see 'Added' in the logs. If this does not show up download the Samsung USB Drivers. Select AP and then select the stock firmware. Now flash it. This can also be done through TWRP
For bootloop and frozen Android/Carrier logo just do Method 2. You usually will keep all your data.
FOR 'VERIFICATION FAILED' YOU CANNOT RESTORE FROM A BACKUP!
FOR BOOTLOOPS AND FROZEN STARTUP SCREEN, YOU CAN!​
Downloads:
Samsung USB Drivers
7.1.1 Stock Firmware
Odin3 v3.12.10
Post any bricks below that you have encountered!
I'm interested in how many variations there are, and how common they are.

Please describe this issue in further detail. Has this been happening out of nowhere, or did you just try flashing something via Odin/Download mode or TWRP.
Also, before flashing did you enable OEM unlock
This also happens when something flashed via Odin/Download mode is incompatible.
Are you still able to boot into the default system partition? If not safe mode?

I should have updated my post, I'm not sure what happened but I flashed stock through Odin and the problem went away, after that I was able to flash twrp and root/install other roms.
It's still weird that the problem happened out of nowhere, not sure what triggered it.
It goes away when u log in to google with the last account that is associated with the phone

Probs OTA. It happened to me my first 3 tries. Ended up factory reseting, and installing fresh via Odin, didn't fix it.
I just turned off auto reboot on Odin, and then pulled my battery on my J7. Booted up straight to Recovery from there.

Sorry I didnt respond.
Looks like you didnt flash encryption breaker. Keep this on your SD Card as its a great way to recover from these errors, and you will need it when you flash ROMS.
Just boot in recovery, flash ashix no verity no encrypt, then reboot into system. You shouldnt have this error.

He's referring to the encryption breaker file ("no-verity-no-encrypt_ashyx.zip") in his first sentence. That is assuming you already had it and should be keeping it on your SD card all the time for flashing ROMs

FOR BOOTLOOPS AND FROZEN STARTUP SCREEN, YOU CAN!​

I have a samsung j700t ud that had the 7.1.1 update installed from tmobile or samsung and it caused the to remain in a continual reboot loop until the battery of the phone dies. Will the methods above repair the issue?
Stuff I've tried:
1. Wipe cache
2. Called samsung and tmobile
3. Used samfirm to download firmware to use with odin that was successfully done but the reboot loop still remains.

Was the update sent out to you, or did you download it from SamMobile?
If the update was sent out to you I'm afraid I cannot help, but if you flashed it from SamMobile use an older version like Marshmallow or Lolipop.
EDIT: Make sure you factory reset device and wipe cache after installing from SamMobile.

How to recover from Verification Failed without losing data ?​Does installing TWRP via Oddin Works and does it able me to transfer my data after installing TWRP ? I dare not try doing it as i have never did it b4

TWRP soft brick?

After months of deliberation I finally decided to root my Note 9. It was the first time I've ever tried rooting and it seems to have gone horribly wrong. To root the phone, I followed the guide in the video titled 'How to Root Galaxy Note 9! [EASIEST METHOD]' on youtube which has an instruction link in the description. As a new user here, the forum doesn't allow me to post links yet, so please just type the title on youtube and it'll come up as the first result.
What I did was:
- unlocking bootloader
- Flash AP file with TWRP version 3.4.0
- Wipe data
- Since I was worried about using a software from an unknown source, I then flashed the official magisk v20.4 instead of the 'N9-S9_root_for_oem_issue_devices_v3' file recommended in the video.
After doing so, the note 9 restarted and showed the error message "Verification Failed, Unable to restart your device. The Integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data.". I allowed the phone to reset.
Following this, the phone restarted and showed exactly the same message of 'verification failed' and no amount of going through the rebooting process resolved the issue. I googled the issue and was advised to flash the phone with Odin by going into download mode. I then tried to go into download mode, but the phone will simply not go into it and tries to restart the normal way. I also tried to connect to my laptop to see if I can flash with odin but the phone was not recognised at all by the computer.
I then tried to reboot using the twrp key combo and this worked. I then decided to try flashing with the 'N9-S9_root_for_oem_issue_devices_v3' file in the tutorial. Yet, this led to the same issue as with the official magisk file.
Looking at some rooting tutorials, I see that some of them recommend flashing CSC, AP, BL and CP instead of just the AP in the tutorial I followed. I then thought that perhaps the issue is I need to install a ROM on the device. I therefore tried to load the lineage 17.1 ROM in the micro SD card and installed it (top left option on twrp 'install') as well as the magisk and disable_dm_verify_forceencrypt zip files.
In hindsight, this was a stupid move from me - I did so I was in full panic mode at that point and desperate for a solution.
After doing so, the phone rebooted and showed a booting animation of a single blue curved line stuck with a circle rolling from right to left on it.
I left it for a while, hoping that it meant the new ROM was booting. 30 min later it was still stuck on the animation!
I then tried to reboot the phone. Pressing power button did nothing. I then tried different combinations and eventually power + volume up + bixby allowed it to restart in TWRP mode.
As of now, the phone is still in TWRP mode. The phone is still not recognised by my laptop and will not enter download mode if I press volume down + bixby when restarting.
I am fully aware that I've screwed up the rooting process and feel awful about it. It was the first time I've ever tried rooting and I really hope it is only a 'soft brick' and that my phone can be saved. I would really appreciate if anyone here could advise what I can do to complete the root process correctly from here?
Many thanks,
Sam
Is there a "download" or "bootloader" option when you press the reboot button in TWRP? My Note9 is on stock, so I'm not 100% certain myself. However if there is, that should take you to Samsung's download screen. This way you can send yourself back to stock if you give up on rooting your device.
BTW, I do recommend following a note9 rooting guide on XDA (it's not too hard to find) over a youtube video, since YouTube videos can often be out of date or a little sketchy.
