Note6pro locked: is it possible to save the data? - Xiaomi Redmi Note 6 Pro Questions & Answers

Hello, I have a problem with a friend's Redmi Note6pro.
The phone suddenly restarted, and since then it turns on, redmi logo for 3 / 4sec and then turns off.
Same thing if I try to go into recovery with vol +, while I can go into fastboot with vol-.
It is FUNDAMENTAL first of all, even more important to reset the phone, save the data inside it (photos, videos and whatsapp chat), the app settings do not interest me.
I did some tests with adb to see if I could access the data (I'm pretty sure, having done the configuration of the cell to my friend when she got it new, that I have activated the usb debugging), but since the phone goes only in fastboot I was unable to access the data saved inside (the command adb device gives no result).
I found a guide to flash a rom with Miflash without deleting the data, but the guide talks about unlocked bootloader, which has never been done on this phone.
Now, since I am not interested in loading a mod rom but I would reload the official rom, is it possible to do all the procedure described WITHOUT unlocked bootloader?
I'm only interested in accessing the cell to save the data, after doing that I can also reset the phone, so I don't necessarily need a 100% "working" rom.
And above all, do I have the ABSOLUTE certainty of saving the data inside the phone (rather than risk losing the data, I will return the cell to the owner and see her)?
Thanks for who will answer

Samsung Galaxy S7 problem - phone stays stuck at boot

Stock Galaxy S7, no root, no dubious apps, only AirWatch Agent: play.google.com/store/apps/details?id=com.airwatch.androidagent required for installing a corporate email client on the personal phone.
Everything worked fine for months, until yesterday, when the app AirWatch crashed, and would not start.
The user decided to reboot the phone. On the reboot, the phone got stuck on the second Samsung logo animation.
Wipe cache, force restart, reboot, reboot bootloader were tried, hoping to fix this boot issue, but without success. The phone still stays stuck at the Samsung logo animation.
What I'm looking for: to avoid phone ROM reflashing, because it has no backup and the data on the microSD card is encrypted.
I want to recover the personal data, by any means.
Any suggestions on how to achieve this?
Thank you.
If you can't flash stock, and have already wiped cache, and the guy doesn't have a backup (dumb), then there's not much else you can do really
I'm not sure which part of the phone the encryption key is stored, but you could try flashing just the Bootloader part of the ROM with ODIN
Also not sure if flashing the same stock ROM over the top, but using HOME_CSC instead of CSC to avoid the factory reset, would mess up the encryption, but as a last resort it would be what I would do
Backups are good, if the data is so important to encrypt I can't see why it would not also be backed up
I understand your point and I agree with it.
As a sidenote, that encryption was required by the app AirWatch, not by the phone's owner.
We'll try those steps as a last resort, but for the moment, we're gathering information, since most of the options are a "no way back" process.
For example, I'm thinking about a way to inspect the boot process, and alter it if there's something there that hangs.
Could this be possible? Is there any documentation about this?

You could trying running a logcat with the phone connected to USB during boot, not sure if it will connect to adb though, worth a shot

If it works it should show you what it's hanging on, no idea how you would fix it though without a custom recovery

Looking for community wisdom - mi note 3 stuck and need to recover data

Hi,
I have a mi note 3, with global ROM. Yesterday, it received an OTA upgrade to 10.4.2.0, and immediately after the install, when the phone booted, it started showing errors about Find My device crashing. I managed to enable developer mode (this phone was unrooted and stock recovery with locked bootloader) and using adb I could stop the find my device crash by removing the package (so it wouldn't reboot) and backup about half of its contents. It did reboot though, and then It just would not boot at all to the system and would just keep boot looping (i never got the home screen).
Having tried a few things with ADB, I decided to do something a bit more drastic and I used ADB sideload to install the same ROM again using the recovery mi assistant option. That worked but still the phone wouldn't boot, so I decided to erase user-data (which according to the xiaomiadb does remove all apps but not pictures and all other stuff). Then the phone did boot, but It got stuck again, this time on the android setup screen where it says something like 'wait a second while we setup your device...' and getting again the same error about Find My Device crashing.
Is there any hope on recovering the data in the phone? I had two ideas but I have no idea if they are stupid or if they have any chance of working:
1-. Unlock bootloader using the Xiaomi app, in fastboot, but instead of rebooting, after unlocking using fastboot to load twrp and then trying to save the data via twrp
2-. Wait for another global rom update, apply that via recovery and see if it does fix the issue with Find My Device
Is any of those ideas realistic? If not, is there any chance to save the data from the phone? even if it implies opening it and so?
Thanks!
The first option seems extremely risky, unlocking the bootloader will format all data - maybe before reboot. The second needs patience, most probably that was the last miui 10 stable. Don't you have a miui account? Most of your stuff is there, you could login from your browser and check it out.
Thanks dpikros. Yes, I have access to the mi account, but I never trusted mi cloud with my data, so I had all sync to mi cloud disabled unfortunately.
I tried installing the previous MIUI, but it's based on Android 8.1 and the sideload won't allow me to use it. I think same will happen with developer ROM.
Does anybody know if the data format happens before or after reboot when unlocking? I was thinking, unlock bootloader and then use fastboot to boot the twrp image (without even flashing it) but not sure if the Xiaomi unlock app will automatically reboot the phone or if it will somehow delete if from unlock directly.
Thanks

Bootloop on stock X3 NFC (Global/EU)

I found the phone in my bag with a discharged battery and does not want to boot all the way. It shows the animated MIUI logo for about 1 minute and then restarts, sometimes showing the menu to switch to 'wipe data' and 'assistant'.
It's all stock, locked, up-to-date, I think still on Android 10 or which one it is. I did not install any new apps and don't even use the phone for anything other than gaming.
I've tried connecting with PC Suite but it doesn't see the phone. Fastboot anything does not work since the bootloader is locked. I know I can wipe data and be done with it, just wondering if there is anything else I can do.
EDIT: I've wiped the data and reinstalled the phone but would like to know if there is a way to avoid this in the future.
Unlock bootloader. This is very important. Then you have full control over the device.
For example the other day I had hard brick because fastboot flash was interrupted. And I still managed to unbrick the device thanks to unlocked bootloader and custom recovery.
It's really hard to hard brick this device. I love Xiaomi <3

My phone continuously reboots itself during booting; only fastboot and recovery mode are accessible -- are there any alternatives of factory reset?

I switched off my phone (Motorola Z2 force, XT1789-06) during ringing. I am not sure if this caused the problem, but since then I can't switch it on. During booting, when it starts to show the animated "Moto" logo, it restarts booting, so I can't get to the normal graphical user interface. If I don't touch it, it repeats rebooting until its battery gets empty. It is not rooted, has latest official Android (version 9, I think, nash_retail) on it.
Until now the only thing I could do is to boot into fastboot mode. There I can log in into recovery mode or do some diagnostics, check some logs etc. As far as I can tell they show no problems at all. Except maybe "failed to read fstab from dt" in /tmp/recovery.log -- is it normal in recovery mode?
I tried some manual reboots from fastboot/recovery menu (on the phone), with and without SIM card inserted, with and without being connected to the charger, but they changed nothing: the phone keeps rebooting at the same stage of booting.
I hoped to be able to adb connect to the phone and pull the files from it, hoping I could use these data after a reinstall. But adb devices show no connected devices. I guess adb is not available in this stage of Android loading. Or is it available somehow?
fastboot devices show the phone, but I am not sure what can I do without triggering a factory reset. E.g. what if I would 'fastboot flash boot boot.img' from the stock ROM? I guess something went wrong on the boot partition, so rewriting it could solve the issue. But I afraid rewriting the boot partition would result in a complete factory reset.
My questions:
* what to try to make the phone booting normally?
* can I change boot config to skip logo animation?
* if booting normally is not possible: can I somehow copy my files from the phone to my laptop (linux)? If I can copy them: is it realistic to be able to use those files to restore the apps' states after a reinstall (after a factory reset)? I would like to keep e.g. my phonebook, SMS, Whatsapp and Signal chat history, OsmAnd favorites, Colornote notes, AndOTP credentials, etc. (I have a backup of some of my files, like photos or gps tracks, synced to my laptop with SnycThing automatically, but many others are not backed up recently.)
* if backing up my data is not possible: can I try to fix the booting issue by e.g. flashing a new boot.img without risking a factory reset? What exactly should/could I flash?
* if none of the alternatives above work: are there any other thing I could try or shall I simply accept the data loss and do a factory reset from fastboot menu?
Thanks a lot for your help and ideas in advance,
Peter

Recover data of frozen Samsung Galaxy A51 SM-A515F

Hello,
my friends Samsung Galaxy A51 crashed while using it, opening a google docs link she received via WhatsApp.
Restarting the phone will only show Samsung logo, then Samsung Galaxy A51 logo and then dead again. No boot loop.
In the morning the wake up alarm set in the phone plays its chimes but display remains black.
Rebooting phone with holding volume down doesn't work.
The phone is not rooted or flashed.
I can enter Recovery mode. Tried to restart system. Tried to delete cache. Tried to repair apps. None of this changed anything.
I can connect via adb but only in Sideload mode. Hoped to unsintall Samsung Browser as this might be a damaged app. But I don't have permission because USB debugging is not toggled. I tried adb restart and adb restart recovery. Phone will no restart to Android. Restarting to recovery works but doesn't solve the problem.
I can bring the phone to Download mode. Btw. none of the tutorials helped to do this. At some point I double-tapped the power button and was surprised to get into Download mode. I wanted to flash TWRP recovery to the phone to get more options to backup and recovery. Unfortunatley the OEM protection did not allow me to flash TWRP recovery.
My friend is from Ukraine and has her Ukrainian banking app registered with this phone and currently no other possibility to access her bank account. Also she has a lot of data like contacts, messages, photos and videos only on this phone. So we can not do a factory reset.
Do you have any other ideas for troubleshooting?
Do you have any ideas how to remove OEM protection without access to OS so I can at least flash TWRP and do a backup?
Do you have any other idea how I could backup the phone?
Unfortunately I still have not been successful to get the phone working again or to backup or read any data.
Just to add another information: I drained the battery to 0% so the phone was totally dead. I was not optimistic that this full power off might help any more than the restarts I did so far. But running out of ideas. It didn't help or change anything.
I'm afraid only a factory reset could at least repair the phone :-(

Without OEM-Unlocking and USB-Debugging you will not be able to install TWRP and if so then all data would be gone automatically anyway, as this is equivalent to a factory reset.
The only way would be to download the STOCK-ROM with "Frija" (quick and free) and flash it with "Odin". Of course, the mobile phone is then virgin and has to be set up again from the beginning. A Google login restores a lot of data. Setting up the banking app again (username & password, etc.) shouldn't be a problem either.
Of course you can also try a factory reset first, but setting up a completely new one is not avoided here either.
Much luck!
