I've got quite a problem.
A few weeks ago, I unlocked the bootloader on my phone and flashed SuperSu to root it.
Today I decided to lock it back for personal reasons, wiping everything.
After it wiped, the phone kinda softbricked. When it turns on the OnePlus logo flashes for a second and turns off.
Won't let me unlock bootloader again, got stock recovery. Tried to use sideload, but ADB can't read the file. My guess it's too large.
What can I do?
I had same problem. Follow the steps. Unlock it again and reboot to the system.
There enable developer option, enable debugging, enable unlock bootloader option.
Rebooted to fastboot mode
Install stock recovery
Adb sideload 3.2 full firmware.
After that reboot your phone to fastboot mode.
Unlock bootloader.
This should do it.

It's like you didn't even read what I wrote...
I said it doesn't boot to system, OnePlus logo appears for a split second and phone turns off.
Bootloader is locked and I cannot flash anything.
ADB Sideload won't read files. Gives the 'cannot read' error.
You know that you can load to bootloader by pressing volume up and power button right?

You should be fine so long as you didn't deactivate the"OEM UNLOCK " option from the developer setting....
do the following
1. press and hold the volume up an power buttons simultaneously to enter the boot loader menu.
2.select start option from the bootloader menu sorry that menu is the boot loader.
3. now connect to pc and use the "fastboot devices" command to see if your pc recognizes you op3 as an android device.
4.type "fastboot oem unlock"
5. flash the custom recovery thru fastboot
5. enter custom recovery and flash your desired rom.
hope this works for you!

And if by mistake I have deactivate the "OEM UNLOCK " what can I do?
I relocked the bootloader. Which wiped to factory reset.
That wipe deactivated the ability to unlock bootloader until reactivated from the system, which I cannot get to because the phone turns off/bootlops before loading it.
This happened quite a few times on this forum, there is really no reason to relock the bootloader on the op3, it is covered through warranty, but u will have to contact oneplus and they should walk u through and send u files to unbrick it if u r lucky

then you better get in touch with the op customer service. they will, from what i know, fix it thru a remote connection sitting.
I have no solution for you, but I wonder if you went back to stock recovery first before you relocked the bootloader? I think if you have TWRP and try to relock the bootloader, this happens. NOT that its helpful to you, but if this is the case and you can verify it, might help others avoid making the same mistake.
As far as your problem is concerned, I would look for unbricking guides. I know I saw at least one guide that lets you recreate the entire partition table manually and make it just like new for the OP2 (and has the company's blessings to do so). So it should apply here as well. Sorry, do not remember where I saw this, but must have been either on xda or the oneplus forums.

I have stock recovery. I did boot TWRP first and let it change system by mistake, but reflashed stock later. That's what might have caused the bootloop once I relocked.
So I guess if you decide to relock in the future, don't flash TWRP, cause it bootloops, even if stock is reflashed.
Bro don't worry now.
I am gonna guide you out of this.
First install an adb package like this.
http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
Now get a toolkit like this.
http://forum.xda-developers.com/oneplus-3/development/toolkit-oneplus-3-toolkit-unlock-t3398799
Try to connect to fastboot and check for your device in the toolkit.
If failed then kill process adb in your task manager.
Now once connected.
Check OEM status and bootloader status.
Unlock if required.
Now.
Push twrp to your phone .
Then boot into it through the toolkit.
Now load a full ROM.
http://forum.xda-developers.com/oneplus-3/development/rom-op3lite-debloated-tweaked-fast-t3404996
Just copy paste it using your file manager on PC.
Them flash first make it boot and then root.
Hope this helped.

Nah, I think this happens only if you let TWRP modify the system partition. But, I have not and am not willing to test it out

Don't test it. I've already done it by mistake.
It replaced recovery with TWRP by allowing the modification of system and even after reflashing stock it'll bootloop on relocking recovery.
So I found something useful then.
Hey, i think i found a solution for you. I don't know if i can post here xda thread links, so search "EDL Mode xda" on Google and the first link it is. Hope i helped
TWRP for US998 (not US-Cellular)
I have simply used existing sources from @jcadduono so thanks to him for the h930 version that simply works on our US998 devices.
All i have done here is changed props to read us998 instead of h930, so asserts should work and labeling on a pc will be correct etc. I don't intend to maintain or build any other versions.
The purpose of this modified twrp and this thread is to provide less confusion for new users of the US998 and for what version of twrp to flash, as the h930 thread appears to be abandoned.
Flashing instructions
1. Unlock your bootloader
2. Fastboot flash the twrp img onto your device - (fastboot flash recovery twrp_us998.img)
Don't let the device boot into system or you will need to fastboot flash again, you need to do the button combo to get into recovery quickly before it automatically boots.
3. Flash a root method or a dm-verity disabler zip.
4. You will probably need to format your data partition before it will boot into system. Because of encryption.
DOWNLOAD - twrp_us998.img
This is built using @jcadduono sources from the H930 version of TWRP found here
Kernel - https://github.com/jcadduono/android_kernel_lge_msm8998/commits/twrp-7.1 and
Device treer - https://github.com/jcadduono/android_device_lge_h930
--->
PayPal donation made for US998 TWRP and the WETA ROM. Thank you.
Question: just like the H930 TWRP worked for bootloader unlocked US998 V30, would this TWRP also work for bootloader unlocked H930/H930G or ANY OTHER LG V30/V30+ variants if they ever got bootloader unlock and full flash commands?

This uses the same sources as h930 so will work for both, though is simply set up for us998. I didn't change anything except device fingerprints

OK, just asking for future. Especially if you update this TWRP and the other one is never updated... Or if another LG V30/V30+ variant gets bootloader unlock and full flash commands through exploit.
I remember when Sunshine team unlocked the bootloader to Droid Turbo XT1254 in November 2015, one of the Motorola Quark variants. One of the Sunshine devs asked "Who can quickly build me a TWRP to work with this?" NO NEED. Quark already had OFFICIAL TWRP! And yes, it worked just fine on the Droid Turbo. Problem was, the XDA mods had split the Quark forums just two months prior (due to locked down Droid Turbo owner complaints; they were tired of seeing custom ROMs, kernels, etc.) -- so all the dev work for the OTHER bootloader unlocked Quarks (XT1225, XT1250) had disappeared, moved to a different location. Very ironic. To this day, Droid Turbo owners mostly have to go over to the Moto Maxx/Moto Turbo forum to get custom ROMs which are fully compatible with their phones. It's just all the dev work is posted over there, because they didn't want to see any dev work -- until their bootloader got unlocked, of course.
So, I'm glad all the LG V30/V30+ are together.
Can't wait to actually use this on my v30+!

Hey Sorry about this but not to be a real dummy but can you tell me/us I know we are still in fastboot mood can you tell us what the button combo is to get back into recovery because I'm not real sure about it

Oh yeah, simply holding power and volume down simultaneously, as soon as you see the LG logo, let go of power button for a brief moment and re-press it until you see twrp boot up.

Thank you Sir I"m new to the LG phone didn't know how to do it.
Just did a system backup but failed. chose External Sdcard since it could not mount internal memory. It ran well when backuping system but when the process of creating system image lasted For some time, the mission was automatically aborted. could not figure out why.

I've been doing backups to internal since day one. Never tried an external card backup. I can't help much as i simply used the source code from the h930 twrp, and never intended to fix or update anything. It was a confusion eliminating build so us998 users knew what to flash
so is there any reason i should update this over the h930 version?

Nope. Not unless you want your PC to say us998 instead of h930 when plugged in in recovery mode.

You cant mount your internal memory because its encrypted with LGs own encryption, and TWRP cant decrypt that.
Solution would be: format internal data, flash the no-verity-opt-encrpyt zip (other twrp thread has a link), and start from new
And the system image backup isnt really needed, except you want to flash it via fastboot (i leave that out always)
can i ask you to upload to google drive or something ebcause androidfilehost seems to be slow compared to downloading from the likes of mega or google drive
Edit: Nevermind
Hi,
Looking for some help getting twrp running. Bootloader is confirmed unlocked.
After the fastboot flash command, it successfully writes twrp.
Then i hold power and volume down, when i see the LG logo, i briefly let up on power and hold it again.
Then instead of seeing twrp, I see the "factory data reset" screen (and the choices are no or yes)
Then it doesn't seem to matter what i choose, I cannot seem to make it into twrp.
can anyone see what I'm doing wrong here?
Thanks

Thanks for the help!! I seem to have another issue. I got past the issue above, then twrp asked for a password/pin (which i removed before I started this whole thing.)
In twrp, i flashed magisk 16, the dm-verity zip and rctd disabler. Now when I reboot, it looks like android is starting but it tells me "Encryption unsuccessful. The password you entered is corrupt but unfortunately your data is corrupt. To resume using your phone, you need to perform a factory reset. When you set up your phone after the reset, you'll have an opportunity to restore any data that was backed up to your Google account"
And there is a "Reset Phone" button....which I click but it just goes back to TWRP and now i'm stuck.
This may not be the correct place to post for help but can anyone help please?
Thanks

In TWRP you need to reformat your partition, not just "wipe". See point #7. Even though they say "wipe", they also admit it's reformat data. And then you have all the stuff you need on your microSD card and can pull from that. (Very important!)

Hi everybody,
I try to root my Blackview BV9500 by installing first TWRP recovery. I use fastboot mode on a linux laptop to do that.
I successfully flash the twrp recovery image, but after that, the phone don't boot in recovery anymore.
It try to boot into recovery, but it reboot in normal mode a few second after.
I tried also with the cmd "fastboot boot recovery.img".
When i flash back the original recovery image, it work, i can boot the original recovery without any problem.
Does anyone have the problem?
Some one can help me to find a solution?
I, too, am trying to do this. I have not yet flashed it... I was going to use the fastboot boot command to boot the recovery kernel before permanently flashing it, to make sure it would work, and in my googling I stumbled across this post. Serendipity! [Edit 3: Although, reading your post again, I see you tried that as well and it didn't succeed for you. For me, it simply tells me remote: command not found, so how were you able to even get that to work?]
All that said... I have the BV9500 Pro, specifically for the two-way radio, so I'm going to try to keep that little tidbit of hardware working in the process. I mainly just want to tweak the menus a bit, tweak the quick settings, get root, delete the Google crapps I won't be using...
On to your problem, though, I can't help much but maybe if we post back and forth our successes and failures we might be able to stumble through it together?
First, I assume you already have unlocked your bootloader? [Edit: Honestly, I'm not sure flashing the recovery would be allowed without first unlocking the bootloader]
[Edit 2: Perhaps this thread might be of help. Different model, but often the hardwares used by manufacturers are similar enough that the same steps generally work. ]
Thank you for the link, maybe i need to flash the complete rom with the twrp recovery with spflash tools, and it will work.
I will try and let you know, but i will make a backup of my rom before flashing it!
For your problem with fastboot, maybee it's because you need to install it. You can use the command "sudo apt-get install fastboot" on a terminal window if you are on linux.
If you want to enter the recovery mode, you don't need to use fastboot, you can simply enter it by pressing Volume Up and Power buttons together for a couple of seconds when your phone is off.
When Boot Mode appears release all keys.
To flash recovery with fastboot, you need first to enable the developer mode on your phone (go to "Settings > About phone" and make 7th tap on the build number, the Developer options will be unlocked and available), and unlock the bootloader of course.
here what is the process i made to flash the recovery :
- i use the command "adb devices" to check if the phone is well connected. (response is like "BV9500S320001179 device")
- then i enter in fastboot mode with "adb reboot bootloader" (phone reboot and ask confirmation for fastboot mode)
- check with command "fastboot devices"
- unlock the bootloader with the command "fastboot oem unlock" or "fastboot flashing unlock".
- flash the phone with the twrp recovery with "fastboot flash recovery recovery.img"
- reboot the phone in recovery mode with "fastboot boot recovery.img"
Normally the phone boot in twrp recovery.
Hope that will help you too.
I am too facing this problem. In case you got any solutions please let me know too.

Yup. Already had fastboot installed for the LG G5 this phone replaced, the Galaxy Note 4 the LG replaced, the MyTouch 4G Slide the Galaxy replaced, my wife's old Galaxy S5 I used in the interims... LOL, I've got a working install. No, the "Remote: command not found" was returned from within.... Whether fastboot or adb, I forget now, but I was able to get the file to flash eventually, after reading your first post, but unfortunately the phone would not boot to it (nor Android). I thought I'd bricked it. Twice this happened. Each time, after about 5 minutes, it eventually booted to Android.
I flashed the recovery from the ROM in the link Blackview sent me and was able to boot their recovery just fine, so there's something in the TWRP that my particular phone doesn't like.

Thanks, I keep forgetting which keys to hold for recovery versus bootloader, so I use the adb command to be sure without having to keep a notepad nearby.
Clearly I don't do this as often as I used to.

Now that was something I haven't done since the T-Mobile G1 days. My understanding was that you CAN boot a recovery without flashing it first if you"fastboot boot {image filename}" but that didn't work for me either. I'm also assuming that the filename to flash can be anything because the device stores it to a partition, so it shouldn't have to be specifically "recovery-verified.img".
The recovery you have... Were you ever able to boot to it? If so, would you be willing to share a link to its download source, please?
I've got to run for a prior engagement, I'll check back later.
Thanks!

I guess i find the reason why the modified recovery image won't boot.
I find an interesting information in a post of osm0sis (https://forum.xda-developers.com/showthread.php?t=2073775) were he say : "some newer MediaTek (MTK) devices use special image signing that adds a "BFBF" pre-header signature, so images will unpack/repack but most likely won't boot unless run through their internal signing tool."
After more search, i find an interesting publication (http://www.lieberbiber.de/2015/07/04/mediatek-details-partitions-and-preloader/) witch confirm that.
They say in conclusion of the publication :
"Yes, I can confirm that SignTool is able to add digital signature information to firmware images. Signed images have an additional header “BFBF” and some fluff which SP Flash Tool checks on a secure device. Apparently some manufacturers merely used the default MTK key for signing the images, making them no better off than a typical insecure MTK device."
So we have to find another way to install magisk to root it.
Root 9500/pro
Mine rooted already....you guys can check on 4pda russian forum
Note : do not use the 17.1 version of magisk there because after reboot the device will freeze if you resboot after twrp 1st install...instead flash 17.3+ or 18+ right after first install of twrp...
EDIT : dont mind the russian language in TWRP as you can change it to english once there

- backup your data from internal SD-Card
- do a factory reset and turn off phone without entering the setup guide after reboot, or wipe via recovery and power off
- Flash recovery.img using scatter.txt with SP Flash Tool
- boot into recovery with hold down vol + and power
- switch TWRP to your language and install Magisk-v18.0.zip and disable_encryption.zip
- reboot and update or install MagiskManager-v6.1.0.apk

you can just download latest firmware and simply backup NVRAM etc with sp flash tool also flash with sp tool, you will have then working twrp with disabled encryption. there are tons of post regarding using sp flash tool on this forum
im using same phone and did these actions on first day and did not have any problem with twrp or magisk
Hi,
I've bought this phone in Pro version. I rooted my phone using needrom.com/download/bv9500pro-bv9500-root/ and adb after unlocking bootloader. Then I failed with errors. Then I used SPFlashTool in root mode with official 2018092919_s32v63c2k_jk_pro.rar rom (I don't find it anymore on the net but 1) I got it on Blackview official forum and 2) I have the file on my own PC) with format+Download and replace recovery with TWRP from Jemmini from 4pda.ru before flashing. OK.
Then I rooted again: format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally.
Beware: TWRP is in Russian language at first boot, so to get it in English, first slide the first slide (allowing writing), then select 'Настройки', then the globe on top, then English, then 'Установитъ Язык'.
Hope this helps.
Then, this is my first rooted phone, so I plan to make a custom rom without Gapps (then maybe without Mediatek Ones and agold too) and remake all functionning with apps from Fdroid. Help needed on a manner of removing a system/vendor app properly. Help needed too to add V4A, as I could see max version supported is Nougat. I announce this here as my first post, but my project will be a full post. If someone want help please ask here or MP me
Note: an update of magisk is out (official 18.1), I installed it and my phone tells me a message that facial recognition was not working anymore then it only boots on TWRP... I reflashed it and my phone boots normally again. Wait and see...
Thanks to Jemmini from 4pda.ru again.

Then I used SPFlashTool in root mode with official 2018092919_s32v63c2k_jk_pro.rar rom (I don't find it anymore on the net but 1) I got it on Blackview official forum and 2) I have the file on my own PC) with format+Download and replace recovery with TWRP from Jemmini from 4pda.ru before flashing. OK.
Then I rooted again: format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally.
Beware: TWRP is in Russian language at first boot, so to get it in English, first slide the first slide (allowing writing), then select 'Настройки', then the globe on top, then English, then 'Установитъ Язык'.
Hope this helps.
Then, this is my first rooted phone, so I plan to make a custom rom without Gapps (then maybe without Mediatek Ones and agold too) and remake all functionning with apps from Fdroid. Help needed on a manner of removing a system/vendor app properly. Help needed too to add V4A, as I could see max version supported is Nougat. I announce this here as my first post, but my project will be a full post. If someone want help please ask here or MP me
Note: an update of magisk is out (official 18.1), I installed it and my phone tells me a message that facial recognition was not working anymore then it only boots on TWRP... I reflashed it and my phone boots normally again. Wait and see...
Thanks to Jemmini from 4pda.ru again.
Bests Regards

It'd be great to have another rom but I'm facing a problem with battery life. Basically mobile network standby drains 5000mah battery every day i turned off from developer option but still problem is there. I have checked every single post on Google but nobody has solution for this. U guys face this problem too?

New update has been released today. It solves some battery issues, but be very careful.
I installed it, having TWRP and now I'm stuck in TWRP. I've tried to wipe everything but I'm still in TWRP.
I'll try SPFlashTool ... hope it works.
Everything restored & updated.
Using SPFlashTool I flashed all files included in 2018092919_s32v63c2k_jk_pro.rar (including original recovery instead of TWRP).
After that, Android booted and then, using OTA, I updated to latest version.

The latest version is not on the forum. I installed via OTA.
But if you mean the previous firmware, there is one link on the blackview forum: http://bbs.blackview.hk/viewtopic.php?t=480235#p795494
SP Flash tools are well documented here: https://forum.xda-developers.com/showthread.php?t=1982587
And a complete list of blackview bv9500 / bv9500 pro files and instructions (in russian): https://4pda.ru/forum/index.php?showtopic=931296
Hope you find what you are looking for.
@kanadali,
for the moment I'm not facing battery drain because there is not simcard in it at this state of my modifications, sorry.
@Reflected_God,
I think this is the link I used, I use the 2018092919_s32v63c2k_jk_pro.rar rom for base.
For all others who faces big problems like me (facial recognition not working then reboot on twrp only, I could reflash my phone with SPFlashTool, the rom and twrp from Jemmini/4PDA in russian only (others don't work for me). I used Format + Download in root mode on Linux. Then format /data with TWRP, then install disable_encryption.zip, wipe dalvik, reboot on TWRP, then install Magisk, wipe dalvik, reboot normally. Do other things. To remove gapps I disabled/force stop it before remove with TWRP. Others apps I can't disable simply remove with TWRP. I test if I encounter bugs but none for the moment. If someone wants to know what I do I've made a LibreOffice Calc sheet log, which evolve when I have time
Hope this helps
Bests Regards
Need Files or a GOOD guide. bv9500 NOT PRO.
If someone could upload the exact files that they used, and the exact same steps, that would be great. Please mention what stock version you have and a link to the image if possible as well. I've followed numerous different guides, with multiple different rom versions, multiple different recovery imgs, used sp flash tool and adb/fastboot multiple times, tried making sure everything was unlocked before each try, have all the necessary drivers, and the closest I get to a functional twrp recovery is a green line that appears at the top of the boot screen before it reboots. Ive tried going to the source, the russian site, but all of the links are 404ed. if not for me, then it would be great to just have this all in one place. Thank you please future hero.
Please include exact program versions (ex SP Flash) as well if not zips of them. I am sorry to be asking so much in one post however I truly didn't know what else to do. And I am typically very good with my google fu xD
I currently have build number BV_BV9500_V1.0_20181026. That seems to matter I believe.
I second the notion.
I have the pro model. I have considered rooting it, but honestly, the phone works well enough as-is without root (for me). However, I'd LOVE to be able to play with different ROMs on this device **AS LONG AS I CAN MAINTAIN THE TWO-WAY UHF TRANSCEIVER FUNCTIONALITY** (i.e. not some "needs-a-network-of-some-kind" "walkie talkie app" like Zello but the real UHF two-way), and I'd LOVE the ability to play with the files associated with the radio to really explore the hardware's capabilities.
Unfortunately, this phone seems more popular in [North]eastern Asia than anywhere else so I don't think we're likely to get much on this forum regarding it unless and until BV become a popular name in the western hemisphere.
Right, so I haven't done these types of things for years and it's safe to say I've forgotten most of it. So my question is do I root first or do I just install TWRP ?
I've chosen to go ahead with this TWRP https://forum.xda-developers.com/showthread.php?t=2678420. But it says Oreo compatible, so I am guessing I can only install an Oreo ROM ? Are there any better(newer) options available ? It is all very confusing, I've tried searching but so many versions of everything, I am not even sure which Odin I need or if it even matters ? I have the GT-I9195. Thanks in advance.

Hey, I am going to try and help you out with this the best I can
You need to use Odin to install TWRP on your device (I'm assuming you have the stock rom currently installed).
The latest Odin should work just fine (a google search should help you find and download it)
You can download the latest version of TWRP from the official TWRP site for your device ([url]http://twrp.me[/URL])
After you download it follow these steps (taken from here because I was too lazy to write it again [url]http://forum.xda-developers.com/showthread.php?t=2449107[/URL]:
1)Turn off the phone.
2)Press and hold home, volume down and power. Download screen should appear.
3)Connect USB cable, and press volume up
4)Start Odin, uncheck "F. Reset Time" and "Auto Reboot", and then click AP button.
5)Select extracted "recovery.tar.md5" file and press Start button.
6)A blue transfer bar will appear on the device showing the recovery being transferred. Check the Message Window in Odin for: "All threads completed. (succeeded 1 / failed 0). The transfer has successfully completed.
7)Long press the power button to turn it off.
8)Hold volume up, home button and power buttons simultaneously to boot into recovery mode.
Once you get to the recovery mode you can install any Rom you want to after making full wipes (wiping data, dalvik, cache, system, internal storage (this wipe is only needed for the first time. I have Lineage Os 17.1 (Android 10) installed on my GT-I9192. On the same thread, you can find the rom for GT-I9195 too.
With respect to rooting, after you install the Rom + gapps, you can flash the latest version of Magisk to get root access. (A simple search will get you the latest version of Magisk too).
(In case you have no idea on what flashing, Rom, Gapps are, there are plenty of videos on youtube that can help you out with that.)
Ookay, I actually managed. Got the Lineage 17.1 installed. To be honest the hardest part was actually installing TWRP. The phone would always replace it with stock recovery and I couldn't get it working. Tried ADB but got stuck 'waiting for device', then I found a 'All in one tool' which i used to Root my device so that I could use the TWRP Playstore app so that I could get the latest version of TWRP....Took me a bit longer than expected, even bricked the device once but managed to get it back and it's now running alright. Anyways thanks for your reply, I guess the thread can be closed now..

The trick is to immediately boot into recovery after flashing it. If you reboot the phone itself, the stock recovery overwrites itself back (useful to remember when you plan to install twrp on your next device).
Anyway, glad you managed to get it working
Just this day, November 23, 2021, I have been trying to flash a custom rom named Syberia OS for daisy(Mi A2 Lite variant). As I have done booting up the device to fastboot(thru cmd command since my power button is jammed), I installed the twrp after booting the image to the device, making it as my recovery.
Now I am set and excited to install the rom, so I went to fastboot again and tried to flash the rom, but it always errors and not installing the rom. It is said "to flash multiple zips, reboot recovery before..." (correct me if I'm wrong), so I rebooted to recovery thru the twrp (since its in fastboot). Now, I did the same, I installed the rom again and experienced the same error so I dont know what to do, I did wiped system, data, dalvik and internal storage (a lot of times and tried to install the rom again), but I get the same error.
Then since I cant install the rom, I went to reboot to system thru twrp, and then I forgot, that I have no OS installed.
So now I'm stuck with the "Your device software can't be checked for corruption. Please lock the bootloader. Please visit this link..." plus arriving to the AndroidOne logo, and it turns off and turns on again with the message and logo, repeats until the battery is completely empty.
Is there anything I could do to go to fastboot again for a clean install of the stock rom? (I promise to not unlock the bootloader and experiment on custom roms again)
(I am sorry if you find it hard to understand, I am willing to edit this thread for better understanding if there are things you dont understand.)
This is what I see after all that happened...:

Hey brother, I had the same situation a few months ago. My device - Redmi 6 (Cereus).
So, I was trying to install TWRP in Redmi 6 and then after trying many times TWRP successfully got installed. But when I tried to boot the device, It stuck in bootloop (Going to fastboot and again booting...). So, the answer is that you first boot into fastboot mode of your device and then download the fastboot Rom of your device, (link of fastboot rom of your device - https://xiaomifirmware.com/download/18010/ ) . Then go to your PC and then extrac
the fastboot file, then connect your phone to pc and go to fastboot mode then open the extracted folder and then click on flash-all (The batch file) and then a new command window will open automatically and flashing process will start. After it's done your phone will reboot automatically. For reference, go ahead. Best of luck!
