Hello,
I have an Asus Zenfone Max Pro M1 device. Few hours back, it shutdown suddenly:crying: and i cannot reboot it. What all i tried are:
1) When i try to Restart, it shuts down after showing asus logo.
2) When i try to access Recovery Mode by pressing Volume Down and Power Button, it shuts down after showing asus logo.
3) I can Only Access CSC FASTBOOT MODE. But no Developer options enabled.
NB: Please note that Developer options is disabled and usb debugging is OFF.:crying:
All tutorials on web says i need to reinstall rom for wich i need to unlock bootloader which will eventually delete my data.
Can someone help me on how i can get my datas back in this situation?
You can't unlock bootloader until you enable OEM unlock in developer options, so there is no method to get your data. You need to wipe
Same problem.... not able to unlock bootloader
Also fastboot rom,qfill failed to repair this problem
Having the same problem. Did anyone figured out what the issue might be or how to proceed? If I would lose the phone, it'll hurt, but not critical. But at least the data ...
Thank you

Hi Team,
Couple of days back i manually restarted My lenovo zuk z1 device and since then it is in endless boot loop, and i am severly constrained on multiple counts which are:
1. USB debugging disabled, and now there is no way for me to enable it, therefore cannot use adb commands.
2. OEM unlock is disabled, therefore bootloader is locked, i have tried unlocking it using fastboot command , but it fails for obvious reasons.
3. Using stock ROM , never flashed/updated either ROM or Recovery .
Things i can do or have done are :
1 . i can access cyanogen recovery and therefore i can reboot to bootloader as well .
2. i can manually power down the phone using recovery menu.
3. i have factory reset phone multiple time and it still reboots and optimizies apps and then again repeats it continuoulsy.
4. i have tried qfil but it only recognizes my device for very short moment, it starts the download and fails at "converting to etl mode" , therefore flashing with qfil is also not working for me.
I am not sure if i have any more options left at my disposal, please help me get out of this mess.
I have a custom ROM(Evolution X) installed on my Mi A1. I wasn't able to unlock my phone using the saved pattern today but could unlock it using my fingerprint. Foolishly, I restarted my phone thinking that would solve the issue. The pattern was recognized during the "Enter pattern to start device" phase but I can't unlock the screen after that as it is necessary to input pattern after a restart. The system UI restarts when I try to unlock using a pattern.
I don't have TWRP on my device as I hotboot it during ROM flashing.
My problems are:
- I can't hotboot TWRP as my default USB mode is "Charging" and to change that I need to unlock the phone
- Because of the above problem device is not showing up on adb/fastboot.
I can however boot into Android recovery.
Can someone guide me on how to unlock my phone?
I'm pretty sure the "charging" USB mode have nothing to do with the problem, as I regularly connect to adb in charging mode. Maybe you forget to turn on USB debugging?
However, I think you can still get into fastboot and boot the TWRP, because I don't think fastboot gonna be affected by that.
If the above cannot help then the only way now is flash the stock rom to clear the password.
So, the thing is - in the morning I have locked my device's bootloader, I did not install anything or else, just in minimal adb fastboot typed "fastboot oem lock", because I needed my bl to be locked to run some apps properly. Little did I know, it was a global rom on a chinese phone, and it also locked my device from booting the system, because it landed in state "this miui version cannot be installed on this device". As many people may know, it made my xiaomi able to run only fastboot or recovery menu, it just cannot boot the system. For the last 6 hours straight I have been looking for any resonable solutions, doable on the spot, but all I can see is EDL. Before anyone asks - I have already tried MiFlash (it won't run because device is locked), also minimal adb fastboot gives error "token verify failed", so I know i have to use something to unlock my phones bootloader. Of course, there is another BUT - I did not turn on usb debugging and mi boot unlock in settings, so using Mi Unlock on pc with fastboot turned on gives result in "Please add your account in "MIUI's Settings > Developer optionss > Mi unlock status", which, as I said, I cannot do.
So we come to my question - is there any reasonable way to turn on this "Mi unlock status" and USB Debug without turning on whole system, or any other way to unlock bootloader/turn on it properly?
Greetings from Poland and thank you for your help
Which recovery do you have? Maybe you could try to restore system and data if it is twrp/fox.
If it's stock recovery give the mi assisant a try, never used it myself though, but worth a try.

I have a POCO M3 on stock version, I haven't tried to root it or install any custom stuff, I was sleeping and when I woked up, my phone was constantly getting into recovery mode, I believe they can enter on recovery mode by mistake or something, just reboot to system and problem solved, but this wasn't the case, there's a message on red below all menus saying "NV Data is corrupted" and I can't do anything, I don't want to wipe data, I need to recover it, but if it is the only way to recover the phone, I'll do it.
Until now, I have tried:
- Booting into safe mode (it says MIUI for 2-3 secs and reboots)
- I've read on internet that flashing a stock rom via MiFlash could help, I get a "couldn't write on locked state or something like that")
- Tried to unlock bootloader with MiUnlock to flash the stock rom (it says that I have to set an option on Developer Options, but the phone can't boot, I can't access Developer Options)
- Also tried to flash modem with NON-HLOS.bin with fastboot (FAILED (remote: Flashing is not allowed in Lock State), because my bootloader is locked I suppose...)
I don't know what to do, if someone can help, I'd really appreciate it, this is my last resource. (I could send it to a Xiaomi Service or something but here in my country there aren't any store or technical support available, only third-party "technicians", they almost always are a scam and charge ridiculous amounts of money and don't even diagnose the issue with the phone...)

USE Any Software Box Connect Phone To EDL Mode Write EFS File 100% Ok
Hi,
I want to install a custom ROM in my Note 4 and upgrade from Android 6.01 to Android 11, and I know that the first step is to unlock the bootloader to avoid issues later on in the process.
I've researched different ways of doing it, and this is what I found:
1. Enable the OEM unlocking option in the phone.
The phone does not have the option to enable OEM unlocking in the developer options of the phone.
2. Go to download mode (starting phone with Power+Home+Vol Down keys).
At this point 3 options should appear. One of them being Press Vol Up to enter Device unlock mode. Well, only 2 options appear and the one missing is Enter
Device unlock mode.
3. Start in Recovery Mode, then select Enter Fastboot.
I started the phone using Power+Volume up+Home to enter Recovery Mode, and a menu presented with several options which should have included the
Enter Fastboot option, but the option is missing in the menu.
4. Use your PC to issue adb+fastboot commands.
I successfully connected the phone to the PC and tried to issue the corresponding commands using adb and fastboot. Adb commands work well. Fastboot
commands do not "see" the phone. (just in case I've tried several different drivers)
At this point I've run out of options, and everything points to the "hard-to-believe" fact that this phone doesn't have the fastboot mode.
Is it possible that the phone does not have a way to unlock the bootloader? or at least checking that the bootloader is unlocked in a way that leaves no doubt about it? (I can't risk bricking the phone based on the assumption that the bootloader is factory unlocked)
I will really appreciate any help in working this sort of mystery out.
Thank you!!

If your phone is exynos, just factory data reset and go to download mode and flash TWRP.

Thank you for your answer!
It is Exynos indeed.
Have you tried this in a similar situation? or in case you haven't, could you please explain how you are certain that this will work well?
Because it is difficult to ignore the large number of warnings about going on with the flashing without being sure that the bootloader is unlocked.
