Stuck on boot after 6.0.1 booatloder/MODEM installation using ODIN. TWRP inaccessable

Hello, good sirs.
I do believe I messed up my G920F phone.
Here are the details:
Using ODIN I installed bootloader/modem referred to in http://forum.xda-developers.com/gal...xtrestolite-deodexed-mod-edition-1-0-t3094423
ODIN tells me it's a success, and phone reboots.
Now it's stuck here, at SAMSUNG Galaxy S6 screen, with a nice little text on top saying "recovery is not seandroid enforcing". I am able to enter download-mode, but TWRP I can not.
Prior to this, I used the XtreStoLite 5.1.1 ROM. Now I wanted to flash 6.0.1.
I tried flashing unikernel to resolve this, no result.
I tried flashing back 5.1.1 bootloader/modem - and ODIN fails to do so.
Am I pretty ****ed or is there a way to fix this?

I had the same problem as yours. Tried everything and no luck. But after I flashed the stock marshmallow ROM for the SECOND time, my phone was back to normal magically...
BTW, mine is 920I.

Just flash this via Odin; (If you're using G920F)
http://arter97.com/browse/S6/kernel/13.1/g920fi/arter97-recovery-g920fi-13.1-twrp_3.0.2-0.tar.md5

#2 I never got around to installing the ROM, even once, though. Our situations are a bit different. ^^
#3 "md5 error! Binary is invalid." is the error I get when attempting to load the file.
I have also tried with a .tar file of a 2.8.7.1 version of TWRP, which worked, but didn't help me get into TWRP -- the boot screen stays ingrained on the screen like a childhood trauma.

I have the exact same problem right here right now !
Help please ? For both of us ?

I had same issue yesterday, G920F, 6.0.1., used Smart Switch emergency initialization, and reflashed twrp/kernel via odin

any fixes for a 920T (tmobile) user? I have the same problem, phone is stuck on "recovery is not seandroid enforcing" but doesn't go past that screen.

Hi mate
Did you follow the instructions given?:
WARNING #2: The Galaxy S7 stock boot image has dm-verity, which prevents you from booting if you swipe to enable system modifications!
SOLUTION: Follow the full rooting steps below, in order, to allow system modifications without the risk of a boot loop!
http://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770

Dont forget to wipe Data in twrp. Otherwise you wont be able to install xposed or other mods.

I did, but I fail to point 8. Shortly before the end pull this combination of buttons, but the recovery will not start, but straight start screen with the error message. Once I managed to recovery get, I installed "dm-verity and force encryption disabler", but he did not wipe, reported that problems mount 'data', etc.

So what is the situation at the moment, bootloop?
Your boot image is probably damaged try this:

In case TWRP is not available use this thread:

Also if you decide you can flash the full stock firmware (odin)..........

Now I have stock rom, because upload this via Odin is only way how to solve my problem. I tryed to upload TPRW and ROOT many times, but always ended with "enforcing" error.

Just curious what was going on?

Bricked Alcatel Idol 3 4.7 6039S

Hi, I came here because I've tried to fix my phone but no hope. My situation si that I'm on a Loop in the booting process where the phone starts the booting process but crashes maybe on the bootloader. My system can see the Port COM 4 and I tried the Mobile upgrade program but after it detects the phone and I click "Update" button the phone goes into the loop maybe trying to get into Fastboot. Lastly, the download fails.
I have never hacked or made any modifications on an Android phone before so I'm a complete noob to this ADB tools and don't have a clue on how to use any tool to recover this phone.
I'm able to boot into "Download mode" and nothing else, maybe there's a combination for getting into the bootloader but I don't see anything about that in the many searches.
Any help is much appreciated.

you device is bricked and you try root install a custom rom or a bad upgrade

First boot into recovery and wipe cache and data.
If that fails try again. It fails again use the below method to restore your phone.
Go into download mode and using the ABD install your stock rom., Meaning your phones original version.
Your phones not bricked.

I tried to install RR on my Alcatel Idol 3 4.7 with using Shara & Firehorse according to this thread https://forum.xda-developers.com/idol-3/general/guide-unlock-flash-root-updated-alcatel-t3751845
everything went accordingly but TWRP never installed. I to boot into recovery and it booted android recovery instead of TWRP. So i tried again using Firehorse but my phone did not boot to download mode, so i cleared cache using the Android system recovery but then i received an error can't mount cache/recovery , so i tried to reset to factory data and received yet again other errors. Force-Restarting my phone ended up in a bootloop that i am not sure how to remove. Please help

Hi, you may want to try a different TWRP recovery. Had the same problem. solved with TWRP 3.0.0 f2fs from Decker's MM TWRP backup. TWRP 3.1 also works with Sahara&Firehose.
Hope this helps.

Rooting mistake! Can't reinstall stock firmware, no root, no recovery.

I desperately need help! let me start off by saying that I'm usually decent at figuring problems out myself I've lurked on XDA for awhile and have had many a phone that I was able to root or fix myself.
However this issue is impossible. I've made a mistake and tried to root my phone without upgrading to the version the root was originally intended for. I was using the CF auto root that I've found here at XDA. Now I am stuck on the "Recovery is not seandroid enforcing" error whenever my phone reboots. Everywhere I've searched says to boot into recovery but this is the message I get when I try to go into recovery?
Also how can I flash the stock firmware when my phone was not successfully rooted? CWRM or TWRP won't work without root access. So that leaves me as follows, I can't flash firmware without root access, I can't get root access or stock firmware without booting into recovery, and I can't boot into recovery without un-corrupted firmware? Do you see this giant loop of impossible I've roped myself into? I've tried using Odin to flash the firmware and I always get the "FAIL! (Auth) message right away. And as far as rooting goes I know of no other way other than with my original firmware.
Sometimes I am able to boot into my phone if I am lucky but I can never get into recovery or factory reset. This is all so frustrating as I had an old phone exactly like this one that I was able to root correctly not before finding out it wasn't unlocked and had to send it back! Is my phone screwed?
My phone is a Galaxy s5 SM-900w8 4.4.2

TWRP doesn't actually require root, it can do what it wants without it. It needs root to use adb while booted into TWRP but that isn't because TWRP requires root to do it, it is because adb requires root.
Root is sometimes used to flash TWRP via an app.
Have you tried flashing TWRP via Odin then seeing if you can boot to recovery?
Also, if you get lucky and the device boots into system, try going to system settings>backup and reset then find the factory reset setting, try factory reseting it that way and then see if you can flash TWRP or your stock firmware via Odin.
Are you booted into download mode when you are flashing stock firmware in Odin?

I've tried doing a factory reset if I get lucky and it takes me into the main screen but immediately it gives me the "seandroid" error message the same as if I press volume up, menu, and power. I am able to boot onto download mode ive tried this to flash firmware but Odin gives me a Fail (Auth) message each time. I'm not even sure if TWRP has a version for my phone yet I'm not sure much about TWRP. If there's a way I can break this chain I'll try anything.

TWRP working so far
I found a custom version of TWRP and thankfully was able to flash it on my phone using odin. I was also able to get the Root working with TWRP as well. I'm going to play around with the phone awhile longer to see if everything is fine. I no longer get the "seandroid" error message while booting up the phone however it does briefly appear upon loading into the recovery but so far TWRP takes its place after a few seconds. It worried me at first but as long as TWRP kicks in each time it's a good sign. I'll leave the thread as unresolved for a while longer in case anyone has any further suggestions or in case something goes wrong but all my thanks goes out to Droidriven!

Good to good, glad you made progress, hopefully that's all you'll need to do.
I don't see how I was much help though. All I did was explain TWRP not needing root.

Understandable, however I never would of thought to try TWRP without your suggestion. It seems when you are stumped the answer is right there all it needs is someone else to chime in and point it out. Like trying to beat a hard level over and over sometimes just give the controller to someone else and they will get it their first try lol.

By the way, when flashing stock firmware via Odin, root is not required. The only time root is required to flash stock ROM is when flashing a stock firmware that has been converted into a custom recovery stock flashable.zip. It is not uncommon for someone in this community to convert stock firmware into a recovery flashable .zip. This is used so that the device doesn't lose root or custom recovery. When flashing stock the normal way via PC, it removes root and reverts the device back to stock recovery. Then the device has to be rooted and flash recovery again. The stock flashable .zip avoids all of that because it gets flashed in custom recovery, this way, recovery is not lost and root is not lost.
This only applies "IF" someone converts the firmware to flashable .zip. Not all devices have a stock flashable .zip available though.

Stuck on Boot screen after flashing TWRP

Hello,
I just flashed the latest ROM for the S8+ (AQL5) and that went well.
Afterwards I tried to flash TWRP, but now the phone is stuck on the Samsung screen.
I then followed the guide I found here to use the BL file of AQF7 in Odin and spam the Start button so I managed to get into TWRP.
Question is, what do I do next? I restart the system it's the same problem all over again.
No one explains anywhere what to do in TWRP to save the phone.
Can I remove TWRP or somehow save the phone (without wiping my data)
Please help

Can you get to download mode? Then go to ODIN and redo your flashing of the OS and then TWRP. After the flash of TWRP, immediately boot into TWRP, and do Verity if you want that, and your root, if not already done. Clear Dalvik/cache and reboot to system.
It is not uncommon for folks, following TWRP flash, to get stuck in boot loop, unfortunately. Can take a little time, but you will get through it and finally to System.

But I thought all new firmware versions are incompatible with TWRP and cause this error.
I might try to install TWRP again if I flash the latest compatible version (I think it's the F7 one).
Does "Verify" in TWRP make that annoying "Your phone is not verified" message go away? The only option is to Reset phone when that thing comes up and I don't want to do that.
I managed to get out of that by reflashing the AQL5 version and just not installing TWPR.
Kind of scared to retry because everything goes wrong when I try to follow the guides on here or youtube
