Hey Guys,
so i got a wierd bootloop problem and for now i didn't find any solution here on xda or somewhere else,
not even a thread where someone has the same problem.
I'll try to give you as much information as possible in a chronological order.
First of all I got the international model (G920F).
So like 2-3 months ago everything was fine, my phone was rooted, got TWRP working and was flashing Roms with no problem what so ever. TW-Roms like Noble Rom and also AOSP/Lineage OS.
One day I wanted to flash UltImAtE NoUgAt A8 Port and that is where the trouble began, dont think it has something to do with the rom but maybe it helps.
So i flashed the Rom(wiped everything except int. storage), flashing was no problem but it didnt boot.
I know first boot always takes some time but after about 20-30 min I forced a reboot (Power+Vol. Down for 7sec).
After that the phone got into a Bootloop(always rebooted into the "first bootingscreen")
I let this process happen for about 15 min. and then tried to enter TWRP via hitting the buttons between the boots which didn't work. I then did "force" a reboot(Power + Vol. Down) which strangely resulted in one final reboot and turning the phone off after the first bootscreen.
So with the phone finally turned off I was able to boot into TWRP and reflashed the rom but the result was the same.
I did the same procedure again to get into TWRP and flashed the Stock Deodexed TW Rom, flashing worked but then the Phone directly rebooted into TWRP. Rebooting out of TWRP or booting the phone from beeing shut down both resulting into booting to TWRP.
So to get my Phone working again I had to flash stock ROM which in my case is G920FXXU5EQDF_G920FDBT5EQD1_G920FXXU5EQCD via Odin.
That worked but of course root and TWRP were gone so I then flashed TWRP via Odin(both newest Versions at that point)
aaaaaand phone straightly booted into TWRP again all the time. I tried different combinations of older versions of both twrp and odin but the result always was the same.
So at the moment I am on Stock, the phone works which is nice but i really wanna get TWRP working again and i have no idea what to do.
I hope someone can help me with that.
Cheers Guys

You do know that if you flash TWRP, you need to use a kernel that has dm-verity disabled or you need to be rooted. Flash TWRP then Flash Magisk through TWRP

As it seems I did not, good thing that its written right at the TWRP download page...
Can't remember doing this when I installed TWRP first but as it seems I did.
Everything is working fine, just flashed Nexus OS and it booted.
Thank you so much dude

I unlocked my bootloader and then tried to flash CWM, but after rebooting it goes back to stock recovery.
Creating a backup via CWM worked fine though, but somehow it won' flash over stock recovery
Anyone else having this problem ?

Yes it happened to me too. There was an option that I could select just before rebooting to prevent this, but it didn't work. I was on stock kk4.4.2 at that time, after installing cm11 nightly, the recovery partition was ok after the reboot. When I later restored the kk4.4.2 to see if it is possible, I had to flash the recovery partition again in order to restore cm11.

Yes eventually Idid. Just like you, I made a backup while at cwm. After the reboot, the recovery partition was gone, and the fallen robot was shown when I selected it. I powered the motog off, did the volume down-power combination, reconnected the usb cable and entered the 'fastboot flash recovery xxxxxx.img' . After a sec or so I pressed vol down , then vol up, and I was back in revovery. Did a test to verify that the backed up kk4.4.2 worked, it did, did it all over again, and flashed cm11. This time, the question about persisting on reboot was not asked, and the revovery persisted.
Ps
I am trying to reach 10 posts in order to report a bug in the developers forum, so if it sounds like I am pulling your leg, I am not.

I did pretty much the same thing right now and just flashed CM11 and it's working. I did delete personal and system files before via CWM but somehow some pictures i took were still there after CM11 installed I'm also still running stock recovery
Everythings seems to work fine but still...strange

Yes I did a factory reset or something like that while on cwm just before restoring. Allways do that for a cleaner install. Since you see your photos, I guess you didn't do that part corectly.
If I where you, I whould do it once more, making sure you are flashing 'CWM 6.0.4.7 Swipe Recovery for 4.4 bootloader: CWM-swipe-6.0.4.7-falcon.img' from the thead of dhacker29.
Also make sure you flash the latest nightly directly from cyanogen. This compination will give you a persistant cwm and a 'official' dhacker29 cyanogen rom.
Only problem I have is with audio on csipclient, and the embeded one, but I will eventually reach 10 posts

I used CWM directly from their site, maybe that's why it isn't working probably.
You're right i should do a clean reflash, but I'm getting sick of constantly reinstalling and configuring everything
Today I tried to finally update to the latest version of crDroid, but ended up having a bunch of issues doing so, and after a lot of troubleshooting and trying to fix it, I ended up putting it into a bootloop of some sort instead.
I'm pretty sure the last thing I tried was installing a different version of TWRP to see if that version would let me properly install the rom, and stop my phone from always rebooting into recovery mode.
Trying to turn it on normally or boot into TWRP leaves it hanging on the "Redmi" boot screen, it can boot into fastboot mode though.
I'm guessing that the only way to recover my phone at this point is to flash the Official MIUI rom back onto the phone, but that also involves wiping Data and losing pretty much everything I've put on the phone.
I was smart enough to make a TWRP of the Data folder, but while making the backup, the console said it doesn't include all personal files or something.
How much of my personal data and files can I rescue from the phone in this state, and how can I do that before it gets wiped when fixing it?
Also, I think I really need some help in actually restoring my phone and flashing the custom rom properly.
No matter how much effort I put into figuring out how to do this stuff, unexpected issues always seem to happen, and turns something that initially seemed so simple into multiple hours of troubleshooting.
The only way I think i've gotten rom flashing to work at all was by wiping everything and installing the official MIUI rom, but I don't want to be losing my data every month when an update comes out.
So, could someone please help me get my phone working again?
Edit: I ended up fixing my own issue by ADB flashing on a different release of TWRP, and then installing fcrypt disabler after the rom but before everything else.

Unfortunately, I can't.
Trying to boot into TWRP just gets stuck on the 'Redmi' boot logo.
I just remembered that you can install TWRP over ADB, and that Peter's one says it works even when the system partition is empty, so maybe the issue is the TWRP I installed and could possibly undo this part of the issue over ADB.
It won't fix the issue preventing my from updating my rom, but recovery only is still better than a soft brick.
Edit: That worked, i've put Peter's TWRP back on, and it's launching into recovery mode/TWRP again now
twrp not boot after successfully flash in this rom

if your problem is not solve then tell me you need to flash a fastboot rom first with save user data.bat file and when it installed then you can install twrp builder 3.2.1. and then boot to twrp this methods working fine,if you recently flashed any android 10 rom then first you need to flash a miui fastboot rom,or flash it via command mode direct only 3 files
first click on extract a fastboot rom and copy boot system and vender file with flash.all bat file and make a new folder then click on flash.bat save user data file to flash these images
or you can do this manually
fastboot flash system system.img
fastboot flash vender vender.img
fastboot flash boot boot.img
then reboot device to fastboot again
now flash latest official twrp builder 3.2.3.1 img twrp and take all your data backup,
in fastboot flash latest miui do not downgrade direct otherwise you lost your data,

In the end, I did try orangefox, and it might have been part of why it worked.
However, the crDroid installation instructions specifically mentions using Peter's TWRP, so I initially used that one.

Thank you for the effort you put into typing up a guide to help me, but I ended up fixing my own problem.
I was able to use fastboot to flash on a better TWRP release, and then get the rom to install properly by installing fcrypt-disabler just after it.

If you can access fastboot, then flash TWRP.... Enter recovery, wipe your system partitions and then flash the Stock MIUI ROM or use the MiFlash tool. Make sure you aren't flashing an older version of the ROM than the onle already installed.

I have the same problem that stated after installing the update for derpfest and I can boot into twrp. Any solution for me?
I got my OnePlus 7 Pro today and tried to install Magisk by patching the boot.img. After trying to flash the patched image, I now have an issue where rebooting the devices leads me straight back to the bootloader. Trying to enter recovery also leads me straight back to the bootloader. I tried flashing the original boot.img I extracted from the OTA update file provided by OnePlus, but it still isn't working. I do not have TWRP or any custom recovery installed. Any help would be much appreciated. I noticed similar threads, however they all installed twrp, though I haven't yet as trying to run "fastboot boot twrp.img" always resulted in it booting to a screen saying "fastboot mode" which wasn't terribly helpful.
Edit: Its not the tmobile/5g/carrier version. I purchased it through OnePlus' website though I forget the exact model number.
Well, "fastboot boot twrp.img" does not work on all devices, sometimes you have to use: fastboot flash boot insert_twrp_img_name_here.imgLearned that the hard way, also use the unofficial twrp from mauronofrio.
Had the same problem as you have, and fixed it with that unofficial twrp.

Did you need to completely revert to stock after the issue, or did flashing twrp fix the fastboot loop?
Edit: Trying to flash the stock fastboot rom currently as flashing twrp did nothing probably because me trying to fix it broke everything. Hopefully the stock rom will get everything back to a working state where I can try again, just this time flashing twrp.
Also using windows this time instead of linux....

Ok, so, trying to restore stock seems to have failed miserably.... any advice is most welcomed qq
OK.... so trying to unbrick the device using the msm stuff, I couldn't even make it to the downloader screen. After holding volume +/- and powering off, my screen is now black HOWEVER the phone gets detected by windows when I plug & unplug it. I have no idea what to do anymore. Someone please help
Figured I'd give the solution here in case someone else is in the same exact problem as me:
Follow the instructions over at https://forum.xda-developers.com/oneplus-7-pro/how-to/op7pro-collection-unbrick-tools-t3956595
I tried to de-brick it using the fastboot roms and all that, no dice. The only thing that seems to have worked was following the above and using the msm tool. Everything wiped, but hey, at least the phone is bootable again and now I have a way to fix it should this happen again. Yay for happy endings.
Edit: Also, following Faith1105's advice, flashing twrp to boot instead of trying to just boot it first worked successfully and from there I was able to install magisk.
Edit 2: Now wifi isn't working.... why life, why...
Edit 3: OK: EVERYTHING IS GOOD NOW. Twrp ran into a boot loop issue, used twrp to flash the most recent android 10 zip, rebooted and was greeted by stock recovery, then used that to wipe absolutely everything and reboot. After skipping through initial setup and making use wifi was working I rebooted again and this time tried booting twrp the way the usual instructions say to, this time it worked for whatever reason so once that started I used twrp to flash twrp's installer and magisk. It looks like everything is working correctly now. If you have the same issue maybe this stuff will work for you or maybe not: I don't know, and honestly I'm now brain dead lol.
My Phone was running Android 11 perfectly fine. Has been for about a week and a half, and I've decided that I don't like the OS. I was going to flash a custom ROM and went to create a nandroid before flashing. Literally all I did was boot into recovery and TWRP got stuck in a bootloop, the TWRP splash screen appears, crashes and then reappears about 2 seconds later, now when I try to boot back into system, TWRP appears instead and continues to bootloop. I can enter fastboot mode but that's all.
So far I've tried
Booting TWRP through fastboot. Failed another bootloop.
Rebooting through ADB. Boots into TWRP.
Rebooting Bootloader. Seems to do nothing.
Does anyone have any ideas on how to fix this ? It seems strange to me that something as simple as booting recovery could do this much harm. I also have a nandroid backup stored on the device from about a month ago, so the data loss wouldn't be THAT major, but I'm also not sure how I could access it without system or recovery access.
Hi , Which version of TWRP use? I think there is an update a new version TWRP 3.5.2 , Try to flash it. if its still not booting try to boot the original Boot of OOS11.
May be this threads will help you.

How can in get out of this boot loop, any advice, answers, help appreciated?
As background my Lenovo Tab 4 10 plus (stock 7.1 rom) had a failed SD card so I replaced the card and factory reset and thought I would try TWRP, Linageos 17.1 with magisk and relevent gapps - this all worked fine other than a Skype issue. I then found an 18.1 rom and tried that and this is where it seems to have gone wrong I set it up in the same ways as the 17.1 rom but with Andriod 11 gapps to suit, did a factory reset and 30 seocnds in I got the boot loop.
To fix it I tried going back to the 17.1 rom set-up that had worked but this then boot looped even with a full recovery reset. I have gone back to the stock rom backup in TWRP again with a recovery reset same boot loop. I have even used the Lenovo recovery tool to EDL mode flash a newly downloaded stock rom and it's still boot looping. I can only think that the 18.1 andriod 11 rom changed something fundimental but I can't find what?
Further I have another problem, the EDL flash worked but it locked the bootloader, however as I can't get in to Andriod with the boot loops, I can't switch ADB mode on so I can't unlock the bootloader to get TWRP up again.
So is there a way to start ADB without access to develeoper settings maybe through fastboot or recovery which I can get in to? Unlock the bootloader without ADB? Does anyone know why after the 18.1 Andriod 11 based rom, I have this continous boot loop?
I have a tb-x704f wich was totally caught in a boot loop, but I manisched to get back to working stock.
I was running firmware s000056 when I flashed twrp without backing up anything. I thought I never would have to go back to nougat, but standby time on lineage os was just not good for me, as I only use my tablet maybe half an hour a day, and I had to charge several times a week nevertheless.
So I tried to get back to stock and awesome standby time.
It was not easy bootloop after bootloop.
Tried Lenovo rescue and smart assistant multiple times, factory reset before and after flash, without SD card inserted etc, but bootloop.
Tried flashing the rom downloaded from the rescue tool with qfil but same result.
I then tried flashing the files with miflash 2016.08.30.0 still the same rom as I thought it had to be s000056. Miflash stopped halfway with some kind of error.
I then downloaded a stock rom from lenovo-forums.ru http://lenovo-forums.ru/topic/24135-lenovo-tab4-a10-plus-proshivka-tb-x704f_s000037_170703_row_qfil/
from the link in the discussion in the bottom of the site.
I had twrp still so from there I got into terminal and wrote "reboot edl" to get into emergency download mode and then flashed away. I presume that I could just as well had gotten in to edl mode by pressing vol+ and vol- simultaneously and then connected to PC holding those to buttons pressed. When the tablet was finished it was off, so I started going to recovery and wipeed cache and did a factory reset. Then booted and instead of bootloop it showed the Lenovo screen with a progress bar underneath. I successfully booted and took a update and then i am back to stock s000056.
The rom I got from lenovo-forums.ru stated it was only for EU and wi-fi model only. I am in Denmark and my tablet is WiFi only.
I think chances for success is greater using miflash than other tools when recovering from bootloop, but then again I don't know. Maybe I could just have flashed the s000037 rom with qfil or maybe I was just lucky, who knows.
But this what worked for me.
I hope this can help someone as I could not with the help of god find any useful help regarding this problem.

Thanks kind man You helped finish my struggle!
The only thing I want to add is that the ROM from the original link is no longer available, so I found the correct ROM using Google from the original filename here https://firmware247.com/lenovo-tab4-a10-plus-tb-x704f-firmware/
