Redmi 4X bootloop after installing TWRP?

Hi,
I'm having a bit of trouble. I had a brand new Redmi 4X, and I was advised to install TWRP, root it, and install the Xiaomi.eu rom until LineageOS is released. I unlocked the bootloader, flashed TWRP, managed to get into it once and now I can't do it again. When TWRP loaded it asked me for a password for decryption but it let me just skip it it seems (not sure if that is the problem) but now I can't boot normally, I can't boot into recovery, but fastboot seems to work okay. How do I go about fixing this?
I've tried reflashing TWRP but I still can't get to it, and I don't really know enough about this stuff to know where I've gone wrong.
UPDATE - I think this is to do with dm-verity and having the stock kernel installed. Now it's too late to undo what I've already done, so I hope to god that someone knows how to fix this.
UPDATE - Right, the problem is solved I think. I had to do an awful lot of googling, and I'm not entirely sure what it was specifically that fixed it. But I found a guide that taught me the fastboot command "fastboot boot twrp.img" which saved the day. Even when my phone wouldn't let me into recovery, it allowed me to flash a no-verity.zip which i think is what allowed me to boot, and it allowed me to flash superSU.zip and then the ROM I was aiming for. And now I've booted into the ROM successfully and hopefully I am rooted and all is well. Plus I can access TWRP as normal now.
Any help would be greatly appreciated

Can you boot into TWRP by pressing the buttons so that you boot directly to TWRP??
Have you tried Command Prompt to boot with commands in to recovery??
And if you get into TWRP you should have everything on the SDCard and then just
format all things except SDCard and then flash from SDCard everything
That is what I would try..and yes it ask for a password but just skip it to get to it
If you can get into TWRP to flash from SDCard then you good to go..if not
Google all the commands for CMD..and plug your phone to the PC and flash everything with the
commands.....
Let us know what is working and what not and what steps exectly you are doing
EDIT
Turn off your device > Press and hold “Power” and “Volume +” buttons at the same time.
After short vibration signal release the power button and wait for TWRP to start.
To boot in stock recovery open “Update” app.
In the setting select “Boot in recovery”.

Thanks for the reply. I can't get into TWRP. Even if I could get into TWRP how would I get files on the phone to flash them?
Is it possible to flash any rom from the pc directly and if it is will this possibly help? I think it's not booting because the kernel is still stock.
I'm not sure what you mean in the edit, how do I boot into stock recovery without being able to boot the phone (and when I have already flashed TWRP)?

Hii
I just have been reading about this bootloop
Go over here and read all of the 6 pages..will not take much time but could help you out much

Hey, I have exactly the same problem. Latest stock rom, flashed twrp in fastboot and got into the boot loop. Nothing works. I can only enter fastboot. What exactly did you do then? What is this no-verity.zip? I can't find anything about it.

I had a problem
I unlocked bootloader then installed redwolf recovery and took a nandroid backup. After that i rebooted to system but stuck into bootloop, could not boot to recovery, could not boot into system, So the only thing worked was that i flashed fastboot rom with mi flasher. And syccessfully rebooted to system with bootloader locked and stock recovery. So, if anyone have same problem you can do the same. How do i install recovery safely again? Should i use TWRP only? Should i flash v3.1.0 with lazy flasher or v3.2 directly without lazy flasher? I don't want to stuck into bootloader again, have to get all data deleted.

Help! I really screwed up...

It all started when I tried to temporarily boot into the TWRP img file. It didn't work so I tried flashing the file to boot_a. Then I installed TWRP through the installer (stupidly didn't wipe the caches) and... Well. When I try to boot into System through TWRP, it gets COMPLETELY stuck at the powered by Android logo screen. No amount or combination of button holding will shut it off and I actually had to let the battery (thank you SO MUCH for non-removable batteries by the way, smartphone manufacturers >_>) drain before it would actually boot again. Rebooting it into Download mode will get it stuck in there too where every time I hold the power button and shut it off, it will just reboot right back into Download mode again. And now, here's probably the worst part. I CAN'T UNLOCK the critical partition to flash when in Download mode, so I can't use the OST tool! When I try to unlock it, it just complains that flashing unlock is not allowed even though the rest of the bootloader is completely unlocked.
TL;DR - When I power the phone up it goes straight into TWRP. Booting to System totally freezes it and the Bootloader puts it in a loop when I try to power it off. Critical partition is locked for some reason. I CAN get around the bootloader loop though and get back to TWRP by switching active slots and rebooting.

Did you flash the TWRP installer to your active boot partition or your inactive one? If you flashed it to the active one, you can't get into system anymore because TWRP is your boot partition.
If you are on Oreo, and you flashed to the inactive slot, and then patched the active slot, you have to reboot into the active slot recovery and flash the Magisk installer to disable verification of the partitions.
If you can get into the bootloader, and you still have the unlock key from nokia, do fastboot flash unlock <unlock.key>, and then fastboot oem unlock_critical. Then you should be able to flash using OST.

This unlocked it! Thank you! <3
I also did have an issue with the OST tool complaining that the updater was out of date, but changing the .mlf file and leaving it unpacked when I opened it in OST seemed to make it work perfectly. My phone is now booting just fine and back to stock!
Now I just need to solve the original problem I had. How can I install TWRP to recovery since the img file wouldn't temporarily boot last time?
EDIT: Apparently unlocking the critical partition seemed to solve the problem of the TWRP image file not temporarily booting as well!

No, thats because you flashed back the May firmware, where fastboot boot was still working properly. It only broke after the august update. If you want TWRP on newer security patch versions, you can get it here: https://bit.ly/nokia-nb1 in the folder "Boot Images". Those images are prepatched, you can safely flash them to your active boot partition. It also contains stock images for restoring before updating.

Yeah looks like you're right. Letting it update back to Android 9 deleted TWRP and made fastboot boot for TWRP nonfunctional again.
Wait, so can I use that TWRP boot image you specified to boot temporarily to TWRP and then run the installer zip? Or will that not work and I'll have to flash the img directly from the bootloader?

You have to flash it directly to your boot partition. fastboot boot will work for nothing (and even if it worked those images would just send you directly into the system)

Alright! fastboot flash boot_a (TWRP image) worked! Thank you so much for all the help. <333

Moto G7+ Flashing Lineage fails -> Touch doesn't work anymore - Brick?

Hello guys!
Yesterday I tried to flash the newest Lineage-built to my new G7+ (XT1965-3, bought in Germany via Amazon), but something went wrong and now I'm afraid, I bricked my phone.
It's not my first flash of Lineage, as I did this in the past already on some older Phones (SII, SIII, S5), but it's the first time, that I have a major issue.
So I followed all the steps on the Lineage-Wiki (on Win10).
After flashing the recovery (the lineage-recovery, not TWRP) I wasn't able to enter the recovery-mode, so the phone booted to StockRom. And probably this was the problem: As it didn't react to VolumeDown+Power, I reflashed the recovery a second time. After that the touch-screen is not working any more.
I am able to enter the recovery-mode and I can boot to Stock-Rom, but in both modes the phone does not react to touch, so I can only use the Volume- and Power-Buttons.
Probably I made more mistakes after that: I thought, that a factory-reset would help, but It didn't. I also relocked the bootloader, but as I saw, that it also did not bring any solution, I unlocked it a second time.
Conclusion: I have a brand new phone, with lineage-recovery, an unlocked bootloader but without touch working.
I also tried to flash Lineage, but the sideload got stuck at 47%. So Lineage is not installed and it boots into Stock, where I can not get any further without touch.
Has anyone any idea, what could be the issue and how I can fix it? I would like to start from scratch, but I don't know, what is the exact problem and if i can for example return to stock recovery.
Thank you!
---- EDIT ----
If it helps: I am able to boot TWRP via "fastboot boot twrp-xxx.img". And in TWRP the touch works!
I could flash lineage directly via TWRP from external sd-card, but i am afraid that after that I won't be able to return if something goes wron.

probably your best bet is to go right back to stock using the LMSA tool and starting fresh. I've seen others encounter similar issues on different devices and always the cleaneast solution was just to role back everything and start over.

Thank you so much. With LMSA I managed to restore everything to stock and touch is working!
So I'm going to start from scratch and finally install Lineage.
Is is indicated to use the Lineage-Recovery, as the Lineage-Wiki says, or would it better to use TWRP?
TWRP gives me the option to flash from sd-card, which seems to me better than via sideload.

Glad your back up and running. Take a look in the lineage thread, but it does appear most people lean towards using twrp, shouldnt have an issue with either however.

I'm having a similar problem. At first touch was fubar but I was able to return to stock using LMSA and now touch works. I can load TWRP with fastboot and even install a custom ROM and TWRP, but installing any custom ROM results in a boot loop during the finding and installing updates part of the phone setup during first boot. I'm tried Evolution X which I was running previously(for about a month, and then a boot loop started yesterday), PixelOS 10, and AncientOS, but all result in the boot loop on first boot after connecting to wifi.

Fixed
I fixed this somehow by manually flashing the latest stock firmware to slot a, and then extracting the evolution x Rom and manually extracting the IMG files inside and manually fastboot flashing those to slot b. I then set b as the active slot and booted up, patched the boot image with magisk, flashed that, and everything works. Not sure why twrp wouldn't do the trick.

Finally had the time to install Lineage. Now everything works.
I followed the instructions someone posted in the [ROM][OFFICIAL] LineageOS 17.1 [nightlies]-thread and the instructions of the lineage-wiki:
1. fastboot boot TWRP
2. sideload the copy-partitions.zip from lineage-wiki
3. factory reset via TWRP (wipe cache, dalvik and data)
4. sideload lineage
5. reboot bootloader
6. fastboot boot TWRP
7. sideload magisk
8. reboot system
Had a little bootloop the first time rebooting the system, but that was because I forgot to wipe data-partition in step 3. Wiping data and rebooting did it for me.
So I have a working Lineage17.1 with root via Magisk.
Thank you for the help!

I had exactly the same problem like you had. Bought a brand new moto g7 plus and after recovery flash, Touchscreen was not working anymore. I could manage to go back to the bootloader, sideloaded TWRP, but side loading lineage worked for me then. It seemed to be stuck on 47 percent, but this seems to be a normal issue, the file was there and after installing, touchscreen worked normally.

Cant flash TWRP

Trying to flash TWRp after unlocking bootloader. First time i tried it, said successful but booted to MIUI recovery
2nd time i tried said again successful, booted to TWRP, formatted data.
Phone then wouldnt reboot to TWRP. Instead it going straight to fastboot. I keep trying to flash again, every time saying successful, then it just boots to fastbooot, not recovery. Any ideas, phones dead at the minute

The best way to recover the phone in your situation is to fastboot flash MIUI.
Get the latest MIUI fastboot ROM for your phone from here
https://xiaomifirmwareupdater.com/miui/raphael/
Install it using this guide from the official MIUI forums
https://c.mi.com/oc/miuidownload/detail?guide=2
If you see a blank page on a mobile browser, set it to view in desktop mode, for this page.
Make sure in step 5 you change the option at the bottom of the Mi Flash Tool to 'clean all' before hitting the Flash button.
MIUI will restore stock recovery when it reboots, so you need to do something to fix this. Flashing Magisk or a custom ROM will automatically preserve TWRP.
If you plan to keep MIUI and do not want Magisk, then you need to flash the vbmeta patcher from here
https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
You need to flash TWRP, then immediately boot into TWRP.
Code:
fastboot flash recovery <path to twrp>
fastboot oem reboot-recovery
At this point you need to flash something in order to preserve TWRP (either a new custom ROM, Magisk, or the vbmeta patcher)

Cheers. You know this is all familiar. Pretty sure i had the same trouble 3 years ago with my mi mix 2
Anyway, lots of hiccups on the way along with this solution. Got to the point now where it says its flashing but it never stops.
EDIT: Bit more research, shortened the path names. Got an error. Commented out device name, got a different error. Switched to USB 2.0 port an FINALLy im back up and running.
Thank you so much for the help.

Phone goes into fastboot mode after I reboot, can't get into system or recovery

My phone keeps getting stuck on fastboot mode.
I'll flash the standard MIUI ROM using the MiFlash Tool, then I flash a custom recovery and a custom ROM(EvolutionX in this case), everything works and I can set up my phone, but as soon as I reboot I can no longer boot into android or recovery. i've tried flashing multiple recoveries using fastboot and straight up booting a recovery using "fastboot boot recovery.img" but it still always go to fastboot. The only solution is to start the process all over again, and obviously that's just not an option since I can never turn my phone off after that.
Any tips?

I think I got it solved, at least I got it to reboot into Android and TWRP.
I used this guide, but I'll write the steps I took here in case you're having the same issue. I wound up using xiaomi.eu MIUI rom, but it shouldn't matter what you use, I'll assume you're stuck in fastboot.
Do "fastboot flash vendor vendor.img", you get this vendor.img from the fastboot version of the official MIUI ROM, after you decompress the .tar.gz it should be in the "images" folder
Do "fastboot flash recovery twrp.img" then "fastboot boot twrp.img", this should flash twrp as your recovery and then boot into it, for some reason it only worked with the official twrp, not orange fox.
Assuming you got into TWRP you should now flash the latest firmware(I got mine from xiaomifirmwareupdater.com) make sure you download just the firmware not the entire rom, mine was named something like fw_raphael_miui... .zip
Format data (not wipe, format, it's a separate option in TWRP), it should ask you to type yes, so do that.
Flash whatever ROM you want
Hopefully this helps you, I hate finding forum posts marked "solved" but with no instructions. I also tried the "vbmeta_dv_shivsom.img" method some threads mentioned but it didn't work
Here's a pastebin of the guide I used in case the original link goes down
You can get all the files I mentioned from xiaomifirmwareupdater.com and the official TWRP site

Out of all that, the one instruction that solves it is the format data step. This is the magic step required. You always need to do this when flashing over MIUI.
Flashing vendor was totally irrelevant.
This will tell you what you need to do.

Thanks a lot man! I'm having this issue and it is beyond annoying. I've lost so much time with this BS.
Edit: Does not help actually

I just had the same problem with my Lamentablet.
I was trying stuff up and restarted it in fastboot mode and got stuck there.
So, ways to deal with it:
adb reboot recovery
rebooted the tablet in recovery mode. All I had then was to press the power button to activate Reboot. Solved! From now on it boots normally.
Meanwhile I had discovered that by typing
fasboot continue
the tablet would resume, but at the next reboot cycle, power down + up cycle or reboot after a crash, the tablet would reboot into fastboot mode...
And I found this out when it crashed (it's not called a Lamentablet for nothing!).
Luckily I had a PC with Linux around. It didn't have the software installed but drivers were already in the Kernel and installing adb and fastboot was a matter of mere seconds. If I didn't have an easily ready PC at hand, this tablet would have become a brick until plugged in and rebooted...

OMG Thanks dude.... I'm literally working to installing custom rom on redmi 7a from stock rom but I don't know what reason that make my phone always stuck on fastboot when format data, before this was fine.
