Unbricking and retrieving files from Redmi 6A but with USB Debugging disabled - General Questions and Answers

My Redmi 6A just decided to reboot itself and get stuck in a bootloop. After 10 minutes of waiting for it to boot, it always redirects me to the Mi Recovery screen.
I do have an option to wipe my data which may fix the problem but I need to recover my files. There is also a MiAssisstant option but it doesn't get read by Mi PC Suite because it requires me to enable USB Debugging.
I can also use fastboot but there is no option to recover my files, only flashing, I am not sure if it can flash TWRP because I need adb to enable bootloader. I can't use adb because USB Debugging is disabled, and I have no ways of enabling it other than booting up the phone which is impossible in its current state.
The question: How can I fix my phone and recover my data using only fastboot?
I knew that I should've backed up my files but this was really unexpected. I usually back up my files every 3 days but it happens that I haven't backed up my recent files from the past 2 days, and those are really important.

Manually turn on USB debugging on Nexus 5?

Android users need help with my phone! I am trying to manually turn on USB debugging (to access files on phone through update thru ADB mode in recovery options, I can install the driver for the phone but won't work until USB debugging is turned on) while my phone cannot boot into the OS. Is there a secret way to turn on USB debugging through recovery mode? (I do not want to wipe the data, and phone unfortunately is not rooted)
USB debugging has nothing to do with adb via recovery. It is an Android only setting. Recovery cannot use it and does not need it.
Adb doesn't work in stock recovery. I wrote a useful thread for people who are new to adb, as you are. You can get to it via the link in my signature. The thread is called "adb and fastboot. What isn't?".
It teaches you how to set it up and use it correctly.

My main issue is that I am trying to retrieve my non backuped data on the phone and the phone itself will not boot into the Android OS.
I have looked into unlocking the fastboot/bootloader but it will wipe the data which would be pointless.
The data on the phone is more critical to me than the phone itself (and yes I was dumb enough to not back it up, didn't expect a flagship phone less than a year to crash on me, but I have learned for next time).
I am looking for any possible way to retrieve the data. I have tried to access the phone from the computer but I cannot access it since USB debugging is turned off and the phone is not rooted or doesn't have any other modifications.
Is there any way at this point I can retrieve the data off the phone with a non bootable OS and locked and stock Android OS?
Y is it non bootable?

You are stuck. Stock recovery, locked bootloader, and OS will not boot. As RootSU mentioned, USB debugging has nothing to do with this. Stock recovery will not connect to adb.
Unless you can get the phone to boot looks like data is lost. Sorry.

Expect it from every electronic device. Especially expensive and complicated ones.
So I actually had warranty left from Google (bought directly from Google) and was going to RMA it but I decided not to because the data on there is important to me and worth more than the phone itself (yes I should of backuped everything but oh well what can I do now). And I bought a new phone so this Nexus 5 will be my little side project to try and revive it; somehow.
I will try to keep going at it, I have small programming/coding skills but it would be nice to find a way to open up the USB debugging option on the locked stock phone somehow that doesn't bootup.
Any suggestions on where I should start to start testing different "procedures"?

[Completed] Enable USB debugging on phone stuck in bootloop

Hello,
I am currently in a situation where USB debugging was not enabled, CROM service status is set to "Locked". This is causing an issue on my International Galaxy S6 Edge (g9250) -- It is stuck in a boot loop and the android OS that was previously installed was wiped on accident through the stock android recovery mode.
I am unable to flash TWRP recovery to the phone, I am unable to use Odin to flash a stock ROM image to the phone, or perform any data transfer between my Windows machine to the phone. Now I am sure this is because I never enabled developer mode and turned on USB debugging, and also because this CROM service is set to lock. When I attempt to sideload using ADB I get error:closed. When using the Skipsoft Unified Android Toolkit any task performed stops at: "Waiting for USB debugging".
Is there any solution for this? I've looked all over the internet and haven't been able to solve my issue -- I'm stuck at a perpetual boot loop because there is no Android OS on the device's partition, and also am unable to flash the stock ROM using ODIN or sideload using ADB.
Is there is a way to turn on USB debugging when stuck in a bootloop? Or a way to disable CROM service on the phone to be able to flash or transfer files?
As of right now the device is completely useless and I have been researching for the past 5 days
Any help is very appreciated, please let know if there is more information needed.

Boot Loop Error Redmi

My redmi7 have stopped working after installing an system update.
It is continuously blinking. I have some critical data which i cannot afford to loose.
i tried to recover with following options but failed.
1.Tried recovery via ADB files installation . Adb devices command was not listing my phone
2.fastboot devices command was not listing my phone
3. completely drained charge thinking it would work
4.I dont want to take risk of flashing the file and losing the existing data.
Any help is much appreciated.
Do you have custom recovery?
Do you have unlocked bootloader?
Can you access EDL mode?
If none of the above then your ONLY option is to send it to a Xiaomi service center. And actually this is much better than following any guide you might find, just tell the technician there to extract the data.

Xiaomi device bricked after reboot

My Xiaomi Redmi Note 8 Pro isn't booting anymore.
I'm stuck in the fastboot screen, I don't even reach the redmi logo in the boot, I need to recover the data on the phone but I have no idea about how to do that.
Any suggestions?
(Already tried going to recovery with power down + volume up, isn't working)
I'm stuck in the fastboot screen

I'm assuming you have Fastboot.
Was USB Debugging ON before the device got bricked? If yes then:
> Download TWRP Recovery for Redmi Note 8 Pro from twrp website. Rename the file to: twrp.img
> Download latest Xiaomi USB Drivers for PC from Internet.
> Download 15-Seconds-ADB-Installer for PC from Internet.
> After Installation is over, Restart PC > Windows Explorer > This PC/ My Computer > ADB Folder > Press SHIFT+Right Click Mouse+Open Powershell Window Here > New window opens
> Transfer the twrp.img file to ADB folder.
> Now you can try connecting the XRN8Pro to the PC (while the Fastboot screen is on)
> On the Powershell window you can type one by one:
1) fastboot devices
2) fastboot boot twrp.img
> Your XRN8Pro phone should boot to TWRP Custom Recovery.
> On PC open another Windows Explorer tab and check if your phones Internal Storage is displayed. If yes you can try to copy your phone data to PC.
> After that in TWRP recovery Press Reboot to Bootloader option, It will show Fastboot screen.
> Download XRN8Pro Stock Firmware/Fastboot ROM from Internet to Desktop only.
> Download Mi Flash Tool for XRN8Pro. Double Click on XiaoMiFlash.exe file.
> Connect XRN8Pro to PC (while fastboot screen is on)
> Then on MiFlash window click on folder to link to firmware file on desktop & click on refresh button, then click on Flash. It takes about 17 minutes (for RN8 devices) to flash MIUI ROM.

Thanks for the reply, this game me some hope, but I don't think USB Debugging was enabled.
I've never rooted or changed rom, I just rebooted the phone and apparently I triggered the rm -rf / command.

No problem, even then TWRP should allow MTP file transfer to PC, so follow all the steps and tell me what happens ok

Just a question, shouldn't I unlock the phone with mi unlocker before that?

You hadn't already? OMG! Sorry. Yup probably would need bootloader unlocking but you can try to lookup steps for Fastboot commands to unlock bootloader on the internet. But it shouldn't trigger a wipe of any sort or you might lose the data inside. Also, no harm in trying to load TWRP using Fastboot i think, just in case TWRP loads.

As said, I never modified this phone, is basically as if it was brand new, OS side.
Maybe I can use https://forum.xda-developers.com/t/unlock-bootloader-without-losing-data.3864667/ to unlock the bootloader without loosing data?

Wow thats great link, I hope it works so you don't lose data.
The link is fresh so you can also ask there. All the Best
Update: I've tried to contact Xiaomi about the issue.
They said they should be able to help me out with this stuff, and that I shouldn't flash my phone because it's really easy to brick.
I understand that it's the usual support recommendation, but it is possible that they know how to fix this issue?
What should I do, go for their way or go for myself?

Is your phone In-Warranty? If yes or no i would suggest go your own way, once purchased an used any device, don't connect with OEM servers ever again for any OTA update coz lots of recent cases about OEM(Original Equipment Manufatureres) killing devices with OTA updates and after that the phone doesnt boot, no recovery no fastboot too, so careful with contacting/updating through OEMs if out -of-warranty specially. Once out-of-warranty always use ROM channels to upgrade to new handroid versions instead of direct OTA upgrade/update, that way you may still be able to roll back the OS to previous version in case you don't like the new handroid version, lots of people don't like handroid 12 but they cant roll back to handroid 11 .
> recent cases about OEM(Original Equipment Manufatureres) killing devices with OTA updates
This is considered highly illegal in Europe, I could sue Xiaomi for that, in case, and would be an easy win.
Btw, I'm the one who bought this phone first, it's just out of warranty since I've bought it in nov-19.
After this data recovery I'll be out of the Android world forever, I just care about my data, currently.

Yes they might not try doing that with uropean customers but they might try in other countries where there no proper legal system for things like these, also they wont do it with everyone in a particular country to avoid suspicion, theyre smart enough to know what theyre doing, but unofficially speaking many retailers have told me about such a thing (OTA Kill Device) happening in Weaker-Law-N-Order countries, so just saying precaution is always good.
BTW i've put my Retmi Noat 10 up for sale, its still in warranty & I havent used it in the last 10 months, no sim card, unused totally, just once I loaded Gcam to check how the camera is, shamshung is always better than chyneez phones mainly coz better build and component-life, chyneez devices only look shiny from outside but it doesnt last beyond 3-5 yrs, not built to last, just use-n-throw devices u knw. Such devices are only made for mass-surveillance in mind not with customers-focus. This A/B partition thing and super partition thing is adding more bad than good.
I don't think that trick will work. even if it would be possible to cheat that easy, encryption key is bonded* to bootloader lock state. so if you somehow magically managed to unlock bootloader without triggering factory reset, your data could no longer decrypted from android OS and is therefore lost.
Xiaomi support answered they can fix your phone, but they didn't say they can safe your data on it, right!? So try to get a full backup off your device in preloader mode (SLA/DAA bypass and VCOM drivers needed)
After that important step you can unlock bootloader with mtkclient, install TWRP and *proof me wrong (xiaomi devices are hackable/have weak security implementations). In any case do not perform factory reset, your backup is always only backup of android OS and therefore incomplete (there are several OS on every device)
btw fastboot doesn't require usb-debugging (that's adb, not fastboot)
Do you have a tutorial about it?

redmi go in bootloader. any ideas what to boot into it?

yes:
my desktop (cause im in bootloader mode i'll need to use it) is artix linux with kde. sadly i cant install on it adb/fastboot and other drivers due to lack of systemd and empty repos so will do it probably from a random linux-based bootable usb...
my mobile is (as was in title) - xiaomi redmi go - european version.
what means ? my mobile have encryption after removing system what makes me unable to boot things... for the now i can still boot stock ROM. although i wanted to remove all associations with google in system (all google apps, bugs caused by removal etc...)
any ideas what i should do with it? wanna have it to tomorrow cause we use our mobiles at work and my current mobile got "marked as over outdated" by boss so i cant use
why noone ?
This same things happen with me also but You need a USB cable to connect your phone to PC. You need to download ADB and Fastboot Tools to your PC and Extract it First of all, you need to enable the developer option and activate the USB debugging on Xiaomi Redmi Go. Now activate the OEM unlock status on your Xiaomi Redmi Go DinarGuru.com

this i actually know. i have one heavily modded lg so im not a newbie. its more about "encryption unsuccesful" broked roms leading to non-booting state (bootloop) etc... nothing from xda surely doesnt work, yep
surely nothing from : https://forum.xda-developers.com/m/techyminati.8245761/ works. was trying loads of times always bootloop. recovery posible to load but then tends to not make factory reset and lock in "encryption unusccesful", and thats worst... im in europe but have global version btw...
dead chat ?
