Phone stuck at a bootloop

Hello, firstly allow me to apologize for my English and long post.
I had a problem with TWRP not being able to perform any action due to not being able to mount data, after searching on the internet it was suggested to flash the recovery with OrangeFox, which I did but wish I hadn't.
Now my phone constantly reboots without showing anything on the screen, was it not for the vibration I would think that it was completely dead. It should be noted that it currently has no working ROM inside (hence why I was trying to flash another one with TWRP which was not working), before flashing OrangeFox when I opened it it went straight to the recovery, although it did show the Xiaomi brand while booting. Now I'm unable to perform any action, including the most important one, accessing the bootloader in order to flash another recovery. Is there anything that can be done by me? Is it dead for good? Do I have to send it to a technician?(I would rather try everything before that)

You may have to re-flash TWRP via ADB fastboot. Once you are done go straight to TWRP

I cannot access the bootloader to flash TWRP. I cannot also use ADB to reboot to bootloader because it doesn't recognize the device, it says "no devices connected" or something similar. When I was able to access the phone I had to change the usb mode to DIMI or something similar, I don't quite remember how it was called.

Same problem here
My redmi 6 is broken with a black screen and vibrates about every 10 seconds or so
sp flash tool might solve your problem; you can download the stockroom of your phone from the official website and try to flash it through SP Flash tool;
it's supposed to work but it didn't work for me; I get an error message ( BROM_CMD_FAIL) and MI flash tool asks for authorized account
I hope that you can fix your phone

Thanks for the information but that that was one of the first things I did; didn't work for me either. I gave it to Xiaomi to fix it, I expected to have to pay even though my phone is still in warranty but strangely they fixed it for free. I didn't tell them how it happened though, I just told them that it had stop working. I suppose that they didn't care to check whether I had done something on the device.

You still can just boot into your fastboot. You can't see it but if you manage to blindly boot into it, you'll see it in "fastboot devices"

Unfortunately, it didnt. I had to contact someone online to flash my phone with team viewer as he had an authorized mi account. It worked like charm
If it asks for an authorized account, then you have no other solution. That's what I learnt as I tried every possible solution I came across in the internet.

I contacted an Egyptian guy in facebook to fix the phone.
Not sure if it is allowed to post his profile link here as it will be counted as advertisement?
It cost me only $4.* (Around 5 dollars in PayPal). That was a year ago, I don't know if he still charges the same amount.

He is an Arab, I dunno if he speaks English. So I can try to contact him for you, but I will take no responsibility. I will link you together if you want. But, beyond this, I won't be involved.
I dealt with him, I paid him before I got my phone fixed, He gave me files to download and then he controller my laptop and used his account to flashy phone. So I only dealt with him once, and he was trustworthy at that time. But I can assure you nothing. It is up to you.

I'm in touch with a guy with and authorized EDL account for Xiaomi, who speaks Spanish and English, but he's not sure I'm plugging the phone in EDL mode, he insists that I must use the test points, I tried everything but I can't find them. So, was your phone before flashing just rebooting in a loop with a totally black screen and just small vibration after some seconds? That Arab guy was able to come alive your phone just with sp flashtools and an authorized account?
I guess my phone is in the same kind of brick that yours were, the only way to detect it in my laptop is keeping press the volume up button after plug and it appears in the devices manager just for a second unless I tried some operation with sp flashtools (error status_brom_cmd_fail (0xc0060005) by the way). Is this the same state your phone was?
Thank you so much for your help.

Which files he asked you to download ? Can tell us plz it will be helpful

Hi @Pradeep1998, as far as I know, the only way to unbrick a phone in that state is using sp flashtools, you won't be able to flash an image using miflash because the phone is unable to boot in recovery or fastboot modes.
I assumed the only thing I need to unbrick the phone is an authorized account to login when trying to flash.
I can tell you what steps I did to get to this point:
Install all necessary drivers on the computer to detect the phone. I presume you already have them.
Open device manager on Windows and plug the phone, in the USB computer port, with button volume + pressed. Wait a while and you should see a new interface show in just for 1-2 seconds. It appears every time the phone boot.
If you can see the device, it's time to try to flash:
Download and install MiFlash Pro. It includes a flashtool version integrated in some way with Xiaomi account, which is necessary to login and unlock the bootloader during flashing.
Download an image to flash for redmi 6 (cereus)
Download auth & DA files for spflash. I'm not sure if it's important use one or another, I use these that I got from some forum.
Open MiFlash Pro app and, in the top bar, you can see spflash, click there and spflashtool app will launch.
Load scatter file from cereus image and DA & auth files. If it throws a validation error loading the files, go to the options and uncheck one item to avoid validation (it has exactly the same name that the error)
Click Download, plug the phone with volume + pressed and when the app starts to flash a login Xiaomi miaccount windows will be shown; if you fill with your username data it will say, unauthorized account or something similar.
I hope this information is useful to you. Greets.

My phone had the same issue with yours ( black screen, vibrates every 4 or 5 seconds, and the laptop detects it only for a second when I plug it pressing power button as I remember, and sp flashtools gives me an error ( BROM_START FAIL SOMETHING) so it was exactly the same error. By the way, according to my knowledge there is no EDL mode for MTK devices ( redmi 6 comes with an MTK cpu).
The guy repaired it with mi flash tool ( mi flash comes with an sp flashtool that kept asking me for an authorized account).
So I think that your device can be fixed with an authorized mi account.

Completely new to this phone. Nice grab! I was able to use your download and 7z zip to extract boot.img from boot.img.p.
I tried to put this file into magisk but no luck.
Have you been able to unlock the bootloader yet?
I tried the fastboot OEM unlock and fastboot flashing unlock when in bootloader mode but it doesn't work.
With someone else's help I was able to locate where the boot.img is located on the phone but unable to extract it.
/dev/block/bootdevice/by-name/boot
Backup boot.img via terminal one-line command
I am trying to make an image backup of boot. The script must work on any android. I think on any Android the boot location is /dev/block/platform/???/by-name/boot My command line find /dev/block/

I did the same thing you probably did to attempt to patch it with Magisk, no luck. I haven't had the time to try further recently. Enabling OEM Unlock and attempting to unlock the bootloader just leads to needing an unlock code, much like bootloader unlocking a Moto device.
I contacted TCL support a long time back when I first got the phone and they were 100% not willing to help with any USA based TCL 10 Pro unlocking. The customer service worker literally said they weren't allowed to help with US based devices. There's no downloads anywhere for the firmware either, which I think goes against Google's agreement to android on a device, but I'm not 100% sure on that.

Android 11 for the TCL 10L has been being pushed in italy. This a large file about 2 to 3 GB. I really hope when we see it on our phones you are able to pull the link from logcat as well. This should be the entire rom. All we have now is OTA patch files. I've tried so many things. I have all drivers fully working even the Qualcomm 9008 Diagnostic driver. I can put the phone into EDL mode.
To put phone into EDL mode you need usb debugging enabled and type in secret code into the dialer *#*#3424#*#* which enables the diagnostic port via toast notification. Then turn phone off, hold both volume up and volume down and plug phone into PC. You will be prompted with the Download mode screen. Hold volume up to enter EDL.
There are ways to backup in EDL mode, I'm just not well versed in commands.

I'll check it out. If its possible to view the code in a tool like dnSpy or extract files from the exe with 7zip, its possible to use with our device, i'm sure as long as the commands are similar

Well you're in luck as it is just a .bat file program simple notepad++ will do.

I will be following this thread with intrest, root could be the deciding factor in me purchasing this device.

Have had the phone for less than 6 months and I'm already having LCD issues. When the display is off, just sitting on a table or something, it'll flash white randomly like its getting an electric signal at random. Its nothing I did. I've never hard dropped the thing. Everywhere I go pretty much is carpeted except work. If manufacturer warranty doesn't cover me, I'll stop recommending the phone to people
I actually switched to an Essential Phone recently. Way better experience, way cheaper too. I have around a dozen of them anyway and have been selling em on swappa (dunno if I'm allowed to say that here, but oh well) lol

Question Hard Bricked OnePlus 9 (LE2113) HELP!!

I hard bricked my OnePlus 9 (LE2113) while I was trying to unlock the bootloader. I tried flashing with Global, EU and Indian variants of MSM Tools but none of them worked.
I'm holding Power and Vol Up to reboot, then I hold Up and Down Volume buttons, plug in with USB cable and start MSM Tool. Every time I try to flash with "Use LIte Firehose" unchecked I always get the "Sahara communication" error at exactly 18 seconds. With "Use LIte Firehose" checked however download completes normally but phone is still hard bricked. This happened on every MSM Tool I tried.
I tried this on two laptops (Win 10 with USB 2.0 ports & WIn 11 with USB 3.0 ports) but ended up with the same results. I'm also using official cable. I have Qualcomm drivers installed.
Can anyone help me? Phone is hard bricked. I can't access anything besides EDL.

Just noticed this thread after your comment in the MSM thread.
Please review my reply. In a nutshell, I bricked my OP9 to a point nothing would work, tried everything for days. Thankfully, EtherealRemnant told me about a specific MSMToolkit for Indian OP9Pros that would get my phone up and running and then be able to flash a proper OP9.
I just compressed it and uploaded it for you, in case you haven't grabbed it yet. Its hosted on mega, so the download should be acceptable wherever you reside on this dirty space ball we call home.
IndianOP9-ProMSM aka The Last Hope
And again, good luck, you got this!

I managed to flash with Lite Firehose but phone is still dead. I had some issues with phone being recognized but it somehow connected. I have also noticed that device under Ports (COM & LPT) is being recognized even after unpluging the phone, weirdly.

deleted because double post sorry

your device is an eu model i would not answer it with the india msm tool or the modded msm tool, you should get it to work with the eu msm tool
I don't know to what extent the modded msm tool has been processed (my concern is that if certain data on the mobile phone is changed from eu to india, I am concerned that the eu msm tool will no longer work with the eu mobile phone afterwards because certain data now identify cell phone as india model)

Hello,first thing i noticed is that msm tool finished with around 200 sec.i think that's not normal.I often use msm tool and every time finishes around over 300 sec.I see you have correct Qualcomm drivers.i'm not an expert but you must investigate a little bit more.good luck

Drivers are correct and I was flashing it with USB 3.0 port .

I would try older stock ROMs first. O+7pro have plenty of them regarding EDL/MSM mode.
Another thing are checksums. Try to check if your download was successfull by counting them from your side and by comparing what you have with provided download. It should match 1:1.

I have the old stock ROM which I flashed it in EDL but phone didn't boot when it is completed phone reboot too but not in normal mode in EDL again

Most often people have bad experience with qualcomm drivers. So make sure that you have some released after 2020 year, as oneplus 7 pro was released in 2020 year. Another issue is related to usb 3.x, better avoid that and try USB 2.0 instead, most of people have best results with older interface of that kind. EDL is kind of old solution, so better to stay away with USB 3.x and use USB 2.0.
Have you got any idea your flash is successful in edl tool? Have you got clean results or warnings/errors?
To be honest with you, I have to use EDL too, because I did wrong upgrade. I used custom ROM instead of stock ROM. Now I have not access to fastboot nor adb via USB either.
try different EDL ROMs, I found 2 threads. one is here, second there. As almost nobody anserws our questions, I will let you know what I did if I do it successfully.

Well, I discovered that I'm in pretty bad situation. In my case not only adb and fastboot does not works. It appears that EDL does not work either. Why? because I connected another oneplus phone over USB to PC and EDL mode was detected spot on. In case my o+7pro, well still same error as previously with adb/fastboot over USB. Something messed with USB on my phone at software side.
So I have to get motherboard get cheap. I do not thik that I can desolder flash or eMMC and revert that so easy.
Sorry Man, can not help you any
further. Turns out my issue is signifigantly other than yours.

Anyways, I have been trying to flash to working condition but MSM won't help. It keeps saying "No valid trg ID" and "Param preload" for a while now. This happened because we tried to root the phone but failed. The bootloader is unlocked, and fastboot works too.
TIA.

Whenever you post asking for help, always make sure to add as many details as possible. Your phone model, variant, current firmware, the tool you are using, the tools you used before, the steps you took before you started facing issues, every detail you can possibly tell. Only then someone might be able to help.

Download the MSM Tool (Global) from this link. Global works on Chinese variant (LE2110) too. Have proper drivers OnePlus drivers installed. Turn off your phone and set it aside, do not connect to PC yet. Run the MSM Tool exe file. Once its loaded, click Start and it should wait for device. Now on your phone, hold vol+ and vol- buttons (no power button), and connect the cable to phone. This will make the phone enter EDL mode. The PC would recognize the device (USB plugged in sound) but phone screen would still be black. On MSM, the flashing would start and would be done in about 4-5 mins. Good luck.
