ASUS MproM1 wont boot up and and not able to unlock bootloader - Asus ZenFone Max Pro M1 Questions & Answers

1 yo phone, warranty expired 1 week before the problem happened. i kept eveything official/genuine, as i didnt want to mess with this one, done every official update.
phone suddenly just turned off, while watchin yt and wont boot up. it doesnt even show the charging animation that usually shows when u put ur phone on charge when its turn off. if u try to boot it, it just goes to the "asus" logo and shuts down , not on bootloop, just goes till the logo and shuts down. if u put it on charge, it just vibrates and shows the first battery image and shuts down. and repeats that loop if the charger power is on. im charging the phone by just keeping it on the fastboot screen.
looked it up a bit, learned its cz of an update(asus forum, twitter is filled with same complaints), so figured if i just unlocked it and flashed twrp itll be ok. now i followed the (2) guides here regarding unlocking and flashing. now the thing is that my device , when on fastboot mode, shows up on my pc (device manager list) when connected, i even updated the drivers of it. also, when the device is on fastboot mode, its responsive ....it shutsdown when the "long press power button to shutdown" is done, so im guessing its not a motherboard issue like the service centre speculated.
BUT, i cannot seem to unlock the bootloader on fastboot, when i click the "unlock.bat/unlock.exe" the cmd just appears and stays there, i even waited(15-20mins), nothin happened. im guessing its not detecting the device or cant access it...and then i looked up a bit on the same issue with the m2 models, i read someones comment bout a "ufi box through isp method with emmc" or somethin which fixed that guys phone.
soo, my question is(are)..should i wait a lot (like 24hrs) on the "unlock.bat" ? is this a motherboard problem(even tho pc detects the device and the device is responsive)? is the somethin-somethin-partition blocked so all i got is the "ufi box" method to fix it? anyother guides anyone can recommend i can try?? what should i do??
edit: i think the reason that i cant even unlock bootloader with fastboot is prob cz i never enabled "oem unlock" and "adb debugging" in developer settings inside the phone when it was running. im tryin to find guides to enable unlcok oem and debugg thru fastboot....but apart from that, the only promising way to fix this feels like the isp pinoout method with ufi box..and thats a hardware related technician job(assuming this device has an emmc cz i cant any google image results showing the pins for that)

I had the same issue as yours, I'm not letting you down but I don't think this problem will have a solution any time soon. Mine shuts down on its own last April, I do gave up already and now rocking a Redmi Note 9.

Exact problem

Had the exact problem on 23rd of this month, almost 1.5 years after purchase. This is insane dude, like was watching some random YT video and boom it happened, i too followed the tutorials and executed the unlock.cmd file which resulted in the same old result of getting upto asus logo and switching off, i tried to brush it off and flash the twrp but since similar to you i've never unlocked my phone , i can't remotely flash it which is the error i get in the power shell. The asus website has an entire thread with similar problems and people cursing at the company and the service center guys are simply saying it's a motherboard problem and brushing there hands. I tweeted at asus india but i won't be taking it to the service center if this is the case.

[Q] I am very stuck - Please Help Me

Hi All,
OK, I am both new and stuck, I have read every page in the unlocking Atrix thread and the one click root thread but I still do not know what is wrong.
I started off by running the one click root listed here, the root went fine and seemed to work, so I proceeded to install ROM Manager but when I tried to back up my phone the process failed.
I googled the error and it turned out that I did not unlock the Boot Loader, so I followed all the instructions that explained how to do it and nothing worked.
Thinking something must have gone wrong I went back to the one click root tool and unrooted my phone, I checked and everything was working and the phone seemed fine.
So then I started down the longer process of unlocking/rooting here , following the steps to the letter and here is where I come unstuck.
I have a UK carrier free phone so after downloading and installing the RSD Lite software I used the SBF_Flash file but when I selected this file the “Start” button remained greyed out.
I researched this issue and found the international flash called intl-fix-try1.sbf, this file looked like it was going to work, the start button became clickable and the process looked ok.
Once I clicked start the flashing started and percentage done went straight up to 98% in a matter of seconds, then as per the instructions the phone reboots but starts to reboot fully, the process % resets and starts from zero going up in increments of 3%, by the time the process is at 65% my phone has fully booted and is sitting at the lock screen, if I leave it there the process will go up to 100% but the status will still say "in progress" until I swipe the lock screen and then it says complete.
I was doubtful that the root had worked but just to make sure I proceeded to move the phone into Fastboot mode and go through the OEM Unlock process but once I have typed in fastbook oem unlock and hit enter the command prompt just comes up with a message waiting for device to respond and nothing more.
Please help as I am really stuck, I followed your guide to rooting my Galaxy tab 10.1 and had it sorted in minutes, my ICS rom installed and everything backed up via ROM Manager so I am not a total dummy.
Any suggestions?
Kind Regards
Chris
when you tried to flash the sbf on rsd lite did you have the phone pluged into the pc and have it put into rsd lite mode
prolly not if you still seen the lock screen
turn phone off then turn on by holding power button down and volume down
when u see fastboot word on the atrix use volume down to scroll to rsd mode then hit volume up and proceed with rsd lite and the sbf
Here might explain it little more..
http://briefmobile.com/how-to-unlock-the-atrix-4g-bootloader
That is exactly what I did, I have just done it again now . . . .
I clicked start
The console/flash starts,
The phones screen goes black,
Then the Red Motorola M appears
The flash progress jumps to 98%
Console Status says something about USB Pass through/phone rebooting
Then reboots and the Red Motorola M appears again
Then progress carries on and goes up and at 16% by now the phone is now fully in its boot process and by 26% it is at the swipe screen
I have the phone in USB debug mode and the usb connection set to mass storage. Could I be using the wrong SBF file?
Thanks
I have tried that method as well as it is uses a different sbf file called zomgunocklite.sbf when I use that file I an error saying sec_exception: febe, 35, 35 I googled that and it came up with a similar issue but it did not help.
So since my first post I have been speaking to ltdanno360 on here, I just wanted to take the time out to say a MASSIVE THANK YOU.
He has taken me through getting my phone back to a usable state and then all the way through fixing up with the latest bits and pieces.
I have taken up a good few hours of his time and I am now a very, very happy Atrix owner.
It is people like ltdanno360 that make this forum and the internet community such an amazing place. Just imagine driving home from work one day and you car breaks down on the freeway, a stranger stops and spends two hours of his day fixing your car before sending you on your way.
Things like that do not happen often in the real world but people like Danno are great examples of what humanity often misses.
Big Thanks Bro
Awesome guy, awesome forum.

Hardbricked stuck on "Your device has been unlocked" and blinking red light

Hey guys i really need your help, i decided to unlock the bootloader of my phone, and so i did without any issue, the phone opened and worked completly, so i wanted to relock it and so i did also without any issue, but i wanted root again so i tried to unlock it again with the same Code with the official unlocking way, but this time the phone have been stuck and red led notification blinking everytime i put in on computer.
If i plug off the power source and try to open the device the red light blink very fast and there is a charging symbol on the screen but then dissapers instantly and nothing the phone turning off.
I cannot enter on recovery or dload, anyone knows what to do? The PC cant recognize the phone if i plug it.
Here some video to check the issue, please turn on the subtitles because im speaking Greek https://www.youtube.com/watch?v=oTkx0ifNhg4
Also here https://www.youtube.com/watch?v=F9dS76eRe0c
Huawei is one of the worst companies i ever saw! Their phones are so easy to brick and they can't be fixed!
Wait until the battery drained and phone shutdown, connect charger again and wait for 5 minutes , it will turn on in erecovery , shutdown and redo fastboot etc carefully.

Dissconnect the usb cable and hold the power button. When it is just about to reboot, plug in the USB and hold the volume down button. This should take you to fastboot OR to error mode...
-------
Huawei devices aren't easy to brick, but recovering the devices is a pain... I hard bricked my device as well a couple weeks ago..
I have tried to wait for the battery drained completly and if you plug the usb while the phone is off the phone is powering on automatically and stays to the "Your Device has been unlocked"
Also with the same method before i plug in the usb i was trying to hold the volume down button and plug it in but it didnt happend it is booting on the same thing.

pls clear actual screen position of ur fone, unlock screen titled as fastboot and rescue or yellow text with black background.
chances are there u get fastboot connection by turning off mobile by power button hold for 7 seconds and phone turned off wait for a while ensure no USB cable connected to phone. then press volume down button and conect USB cable, you will see fast boot and rescue screen. now issue command fastboot devices. if u see ur devices serial number there then follow further fasboot procedure mentioned in other threads,
Fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system.img
above files may be obtained by extracting update.app for ur phone stock image by huawei extractor. you have to work for 2 days constantly for unbricking phone. I have gone through all these processes last week.

Hi, I have a similar problem: "your device has been unlocked and can't be trusted". I cannot enter fastboot nor with the two buttons method (power + volume down) or the three buttons method. I messed up with the EMUI, I guess. Infact, I unlocked the bootloader, relocked it and tried to unlock it again to flash a custom ROM. The first time I unlocked the bootloader, I tried to install TWRP but something went bad, I do not remember what, but I decided to relock.
Now I am stuck with this message. But....sometimes, I can't understand WHEN, I can enter my phone Last time it was when I tried the above solution (only volume down and usb cable, without the Power button). When the phone turned on, HiSuite recognized "a phone" was connected because the software turned on, but it couldn't really see it. I went into the Developer Options on the phone to turn on OEM, but it was grey and I could do nothing :crying:
Full of hope because the phone turned on, I then tried to flash the content of the SD Card (where I put files extracted with the Huawei Update Extractor) by holding the three buttons (power + volume up + volume down), but again it appeared the "your device has been unlocked" message.
Now the phone is off. Once, in the meantime, it appeared a red flash on the screen for one second, I am not sure it is related to the battery, it doesn't display a battery but only a flash.
I cannot enter fastboot in any way, I cannot flash from SD card, sure I cannot rollback because it implies flashing.
My only hope is some command to be given when I can enter the phone. Anyway, I sent it to repair (not official, I have obviously no guarantee anymore) and they sent it back to me: they didn't know what to do.
Any idea? Thanks a lot!
PS: I will read your replies as soon as I can but I have very variable ad unstable working hours!

I think the red light blinks cause you are critically low on power. Leave it plugged in. Ignore whats on the screen just leave it plugged in for a few hours and leave it alone.

Same here with a BLN-L21 (Honor 6x)
The phone will not charge with this method. Try to let it plug one night, and no charge !
@Meticulus this was the question felix ask you: is uboot (booting with sdcard) is possible ?
Fixed for me with buy an honor 9 ... but investigate to revive my honor 6x.
For now i have maybe found how to shutdown phone, to charge battery (with shurtcut two point in motherboard) but don't know if phone charge for the moment because there is no light
Solution for the moment but difficult AND / OR expensive ....
1. Remove emmc and repair it with a JTAG box.
2. Try to boot with uboot (but probably won't work)

Hello, can ask you some question about how you have hardbricked this phone ?
My honor 6x is same bricked, and red light too. So the big question is THE FIRSTIME BRICK = phone was FREEZE can't reboot and can't do nothing. I have wait for empty battery, and now dload and all is not working ?
I will try to charge my battery out of phone. For me it's like the phone never charge ... but i will try with a charged battery and plug unplug battery connector. It's like red screen low battery change boot mode ...

Its not actually mine and it was long time ago, but the owner told me that he unlocked bootloader with the official way, relocked, and then he unlocked again the third time the phone died.
Hello.
me too, he does not want to do anything anymore.
he only knows this '' your device is booting now '' screen with the red LED flashing.
whatever I do, it always starts on this screen. I think you have to change the motherboard.
Do you know where to find it at a reasonable price?

I fixed mine today. I just had to wait for 5 hours for the battery to drain. then when it shuts off i waited 10 min. after that i started the phone and i let me choose to continue to the phone.
I dunno if you have the exact same problem but thats how i fixed mine.
And after that i tried factory resetting (cause bluetooth and NFC didn't work) but then it got stuck again. so i waited it out and it worked once again.
Too scared to do anything to my phone now :/

Stop buying huawei phones if you are into custom roms or root. They made the phone easily brickable and they removed the bootloader unlock site due to some stores installing malware into phones. But hey, they couldn't simply do what Xiaomi is doing eh?

LG V20 Device is Corrupt and BootLoop

Hey all! Hopefully you can help with this issue. I have had this phone through T Mobile for a few months now, and am stuck in a real bind. As the title suggests, I have a boot loop issue and Device is Corrupt issue as well. The red Triangle is an issue with the OS. I cannot get the phone to boot to Android, nor get into recovery. I can however bring up the IMEI menu, which displayed the IMEI. I really need help, as this is my main contact for job search and family.
Im on sprint so this method is unavalable to me.
Tried LGUP? you have the ability to shoehorn a KDZ file in whicj will bring your phone to stock
As this is a no go for the ls997 i have no idea how this is accomplished. Check the forums for said method.

I will definitely look into this. I just want my phone back TT.TT lol
I wanted to chime in, I've got the same issue as OP.
What's broken:
turning the phone on normally - displays an LG logo; gets stuck, won't proceed past this point
holding VolUp while connected to PC - displays IMEI; won't enter download mode
holding VolDown - displays IMEI; won't enter fastboot or recovery mode
So, there's no way to get to recovery. I'm stuck with a $400 brick that displays a logo or an IMEI number.
LGUP w/Uppercut doesn't work either, shows up as an unrecognized device, and it wouldn't matter if it were recognized, because I can't get the phone to download mode to restore a stock .kdz.
I just ordered the phone on the 4th from Amazon, so I'll see if I can return it/get a replacement, but I'm guessing I won't be that lucky. It does display the orange "WARNING: Bootloader Unlocked" screen, meaning it's very easy to see that the warranty has been voided, so I guess whatever support I get is a crapshoot.
Again, since I can't get to fastboot mode, there's no way to restore to stock and relock the bootloader before returning it. Kinda dug myself into a hole here with no other options.
I got it to install! Now to just play the waiting game and see what happens. I had to do some finagling to get it to work, but it works.
I found a H91810 KDZ, I started Uppercut which loaded LGUP, click on UPGRADE, then selext the KDZ file from where you saved it. Should work. Also make sure all of your drivers are up to date.

Ok, I seem to have my device back up and running. The step I was missing was to remove the battery, disconnect the USB cable, put the battery back in, hold volume down but don't press power, instead connect usb cable. This got me into fastboot and I was able to recover from there.
this might work for you!

okay so holding VolUp while powered down and plugging into pc will bring up download mode if its still there,
if you have twrp installed prior to this red triangle then pull battery/put back battery. hold VolDown and power at the same time, as soon as LG logo comes up release power button (fast) and then hold it back down again while never letting go of VolDown. this is the factory reset hit yes for both questions and it should reboot phone into Recovery mode. some times you have to do it twice to get recovery (twrp) to pop up! i hope you have bootloader unlocked and twrp.

I got it to install! Now to just play the waiting game and see what happens. I had to do some finagling to get it to work, but it works.
I found a H91810 KDZ, I started Uppercut which loaded LGUP, click on UPGRADE, then selext the KDZ file from where you saved it. Should work. Also make sure all of your drivers are up to date.

If using the LGUP you must get the G4 Dll file for it to read the phone and com its on. i believe its a common.dll file i cant really remember...

Ok, I seem to have my device back up and running. The step I was missing was to remove the battery, disconnect the USB cable, put the battery back in, hold volume down but don't press power, instead connect usb cable. This got me into fastboot and I was able to recover from there.

What model do you have?
You can put the phone to download mode (even if screen displays glitchy gibberish screen) by taking out Battery first, put battery back in after 10 seconds. Then just press Vol up and while keeping it pressed, connect to USB. If you have drivers installed, your phone will get recognized by LGUP. Now from here you can flash the stock rom.

OP6T bricked hard

My 6T is currently a paperweight (bricked, screen won't turn on, no fastboot, no nothing) and here's the succession of events that led to it:
I live in the US and bought the unlocked 6T.
1) A few weeks ago I rooted it with same steps described in this post --> https://www.xda-developers.com/oneplus-6t-unlock-bootloader-root/. Everything seemed to go well, I had Magisk and my phone worked just fine.
2) About a week later I got a notification that my phone had a software update ready. I idiotically obliged and installed it. After the install, I still got the bootloader unlocked screen at start up so I thought my phone might still be rooted. However, I couldn't download any mods on Magisk and my root checker said I was no longer rooted. So basically, my phone appeared rooted (apps like Google Pay wouldn't work, I got the warning about the Bootloader at start-up, etc.) but I no longer had the benefit of being able to install mods through Magisk.
3) A few weeks later (yesterday) I decided I would explore options for un-rooting, mainly so I could use Google Pay again. Remember, my phone wasn't actually rooted anymore, since the update. So I thought locking the bootloader should fix my problems. I did that with fastboot oem lock and then my phone was stuck in a fastboot loop. I tried every option in fastboot and would just end up right back there. I started looking for fixes and came across the MSMDownload Tool --> http://https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892. I downloaded the driver, it recognized my device, I downloaded the tool, then ran it. At 16 seconds, the download stopped and I got an error saying "Sahara communication failed." After looking up a fix that involved holding down the volume+ button, I decided I'd try again. This is where I f*cked up. I unplugged my phone without stopping the download, and that leads us to this very moment. My phone does not turn on at all. I have no access to fastboot or anything. My computer does recognize it when I plug it back in (I'm on Windows).
If you read this it's probably obvious that I only know enough to be dangerous and bricking my phone was inevitable. Feel free to call me an idiot, I only ask that you provide some useful information, preferably on the subject of getting my phone working again. Thank you all in advance. I hope this post isn't redundant. I didn't find anything on here that was a fix for my situation. I'm also open to contacting OnePlus if anyone thinks I should do that first. I genuinely thank anyone that takes the time to read/help! xd
Use the msm tool...doesn't use fastboot
Edit...nevermind
You need to get your phone to show up as "US8_BULK" like in the MSM thread you linked. You can do this even if your phone wont boot properly. I have done it multiple times before. When in the Qualcom flashing mode the screen will not light up at all.
Hold all the buttons until it resets. This could take up to 30 seconds of holding the buttons. The just follow the steps in the MSM thread starting with this one:
Power off the phone, then hold for 5 seconds vol up and plug the usb to computer. Now you have to see US8_BULK as new device connected and you can also see in device manager; if you can't notice it, repeat the process until you see it (power on, power off, hold...) there is a full youtube guide for op5 and it's the same process - (https://www.youtube.com/watch?v=PpLvmID1wdI)
Edit: It can take some practice to get the timing down, especially if your screen is not coming on at all. Just keep trying as you will be able to get into that Qualcom flashing mode unless there is physical hardware damage to your phone.

Awesome, that worked! I kept seeing I needed to hold volume+ and power but holding both and power is what actually worked for me. Thanks a lot my friend
@lapitman, glad to see that you finally got it to work!

HELP! Stuck in Boot Logo w/ no Recovery Mode

Ok so before I started writing this I had only one problem now I'm worried my problem has gone from bad to worse.
I updated my 6T to 10.3.2 from the latest Beta after the process it prompted for a restart, upon restarting it got stuck in the boot animation. I tried going into Recovery and Download mode unsuccessfully so I went through the forums a bit and saw that someone who had the same problem successfully entered Recovery mode by pressing VOLUME UP+DOWN+POWER buttons simultaneously, I tried to do the same and my phone turned off and now it doesn't turn on! :crying:
Has anyone experienced this or know how to fix this? Any help will be much appreciated. Tia!

These should be clarified:
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Turn the phone off, let it sit. Then try turn it back on. Any response?
try to shutdown phone ...hold vol+ and power button for like 15 sec and restart your phone if this didnt work then u can try MSM tool
Thanks guys, got it working using MSM Tool!

You are likely going to lose your data. Know that going in if its not already backed up.
If you have the fastboot menu you can use the fastboot roms.
Or my least favorite option or what I would try last, MSM Tool (Tmobile 6Ts use a different tool).
IMPORTANT if you want to try and recover and data off your phone first, go to fastboot, and try and "boot" the TWRP img (not the installed one, one from your PC using the fastboot command). If that works you might be able to recover data. If that does worm, try dirty flashing the last ROM you were running and see if it boots.
No worries!

Hello, I am sorry to hear of you having this issue, I just went through 3 1/2 days (off and on) of recovering my T-Mobile OnePlus 6t which I found a way to get my unlock code within 2 weeks of having it, so I rooted it and put a custom kernel on it, stuck on 9.0 never let me update as I was not familiar with A/B partitioning, yet! The answers I saw to your questions were spot on, I just had a little to add to it and I'm sure I am not alone. Real quick let me list what has gone wrong on the rare occasion it hit the fan with the 6t...
- When I would accidentally and rarely let my battery die it seemed like it took forever to get it to reboot, I mean it sat on my desk of DOA devices for 2 weeks!
- It often seems like the buttons do not always respond properly and never have when I needed them to. Been through this before, I've bricked and unbricked and flashed and re-flashed and wiped all weekend and I like Android 10 and all but seems everything is different for every build, and everything seems to have to go in the right order with the exact right file or you wind up in a jam, period..
- That said, the previous person that answered your question has likely encountered similar, I've heard of right down to the buttons not physically working, but I have been a Smart Device Master III Technician for over 5 years, i know my buttons were not broken.
- Most likely culprit that I just handled and worked, i did have to use the MSM tool, several times - and re-unlock the BL, several times I would not even get the chance to get to fastboot, just a screen saying Build and Hardware not a match"" in yellow letters and it just bootlooped. No fastboot is no good, but when you said the tool would show some signs of working but then not, I have 2 solutions that I needed on diffrent occcasions.
1 - As mentioned fully try other USB cables, and ports, if you pull the usb-c out of the port and hold <power + vol up + vol down> eventually it will do something, very picky, sometimes gotta move your fingers to different spots on the buttons and also after 15-20sec let go of power and hit and hold it again... after a few seconds before it vibrates stick the cable in connected to your PC and the screen will be black (obv) but the msm tool will pick up on it. I know about the cables because I take good care of my phones and cables and charging ports, however on my final fix today it showed in msm tool it was connected but waiting for device.... Fed up i put the phone down and moved the usb cable a little bit and it picked up on it and did its thing! That part was just the cable, getting into qualcomm mode or w.e. is a bit tricky sometimes.
- Also someone said set it down for a while and come back to it.. THAT WORKS!! Let it fully charge and often just plugging in charger turns it on, bootloop soft brick or however have you, very simiilar to an Apple device and their DFU (don't f up mode cause screen is black..)
I hope that helps you get in touch with your family and friends.. Whatever you do, don't give up bc if you have not got it yet, you will! One other note, there are a few different msm tools available and they look the same some same size, but the one that supposed to work on my phone didn't and one that they say only a fool would attempt to try actually saved me, so if all else fails, use a different msm tool/usb cable and you will get it! I don't think I can post links yet I am on here very rarely, but plan on more! I have received so much help from XDA throughout the years on thousands of phones with just software issues alone, aas well as guides to my own phones. I would be honored to give back as I also have some extensive knowledge on many devices but I am a noob in comparison to many! Stay safe, good luck and please update and let us/ me know how it worked out for you. If i can help further I will, I have every firmware file for the OP6t, recovery, tools, software, this is not new to me but I feel your frustration!
