Any System Update = Constant Fail - Fastboot Screen - Android Q&A, Help & Troubleshooting

Hi All,
I'll explain this as clearly and simply as possible and hopefully someone can help
My oem 3T ran out of power, plugged into dash charger and no led, power button held down for 10secs and entered fastboot, got to some options by holding power and volume down, but none of the recovery,wiping cache,delete everything options worked (would always go back to fastboot)
I ended up following the unbrick tutorial on here (link - https://forum.xda-developers.com/one...us-3t-t3515306)
and got it back to factory state, HOWEVER, I cannot update the OS without it going into fastboot, if I THEN turn off and turn back on holding volume down it doesn't take me back to all the options I had (wiping cache, reset system settings ect) but shows me the android logo/loading screen with something like this in yellow text:
>>>> changing to aging
then I'm back to the original state before I tried to update the OS.
Any help would be MASSIVELY appreciated!

I think I've discovered the problem! - my volume button is stuck on up also!!
didn't realise this with the power button held makes the phone enter fastboot mode is any case

Power button problem

Hi. I did http://forum.xda-developers.com/showthread.php?t=1586570 this to my phone and since then every time I turn it on the black screen with AP Fastboot flash failure appears and not the Motorola logo. Not that I turn off my phone that often, but it's frustrating. I have to pres Vol Up/Down + Power button and choose Normal boot everytime I want to turn on the phone. Please explain me how to unroot or I don't know, I have the phone for 5 days now. I want it to look like I've just opened the box
P.S. Already tried Factory reset, doesn't help, still the black screen when I press the power button to turn on.
P.S.2 My system version is 651.167.3370.XT910.AmericaMovil.en.01 if it matters.
Really? The link I posted is from this forum. Come on. I should be able to undo this flash I've made and really return to fabric settings.

Moto G - Phone will not boot, please help!

Simply, I flashed the xposed framework for my device (which I know works as I have done so before.) However, I may have pressed the wrong power off selection in the TWRP menu. Now, my phone boots however, at the point the lockscreen etc. should show, I jus get a black screen.
As far as I'm aware, all I need to do is power off the phone and power it back on again. However, the phone has a unremoveable battery. I do NOT want to reboot the phone (that is holding the power button / power button and volume as neither of these have an effect other than a reboot into the same problem.)
Thank you to any help!

how to boot into recovery mode through pc ?

Hi,
I own galaxy s3 i9000, currently on custom rom. My phone automatically rebooted and got stuck on bootloop. If I am able to enter in recovery mode, i can wipe cache(which may can help to get out of bootloop). But the problem is I am unable to enter into recovery mode because phone's volume up button is not working and my phone auto reboots every time after power off or reinserting battery. Is there any other way to clear cache or enter into recovery mode?
I dont want to flash my stock rom via odin (because i didnt backup my some important apps and msgs), this will be my last option.
sorry for my bad english
The normal way I get my phone into recovery mode from the PC is using ADB and the command: "adb reboot recovery". However, I bet this won't work in your case for one of several possible reasons: depending on when the bootloop occurs in the boot process, the phone may never reach a point where ADB is able to see your phone in the first place; if this is happening after a flashing a new custom ROM, then also it's unlikely that USB debugging is turned and the PC is not yet authorized to connect with it over ADB.
Another thought, could your power button be stuck down? I had a GS3 SCH-I535 several years ago and the power switch went bad on it, it would keep rebooting, shutting down randomly, or I'd be unable to turn on the screen. I had a switch replaced and it was fine after that. I don't think it's normal for the phone to automatically boot up when you reinsert the battery, that's why I bring that up. Maybe you can wiggle the power button a bit and try to unstick it if that's the case.
I tried to remove and stick back the power button again, but still it didnt worked. By the way fixing power button will not help me to get into recovery mode as my phone's volume up button is also not working, and recently I found out that I cant enter into download mode too because when I press respective buttons (volume down + home + power) for download mode, it gives warning msg to click 'volume up' buttton to enter into download mode or 'volume down' to reboot. Therefore again volume up button is required to enter into download mode too. So the only option remained for me is to visit service center and fix the volume up button.

[Q] Lineage OS / screen unlock not working / can't get to TWRP

Old LG G5 I had previously installed Lineage on. Was in a drawer until I decided to charge it up and let one of my kids play games on it. When I input the correct screen lock pattern, it goes black, then comes back to lock screen.
I am able to hold power button to then select power off, restart, etc. From power off, I power on and get the orange triangle recommending to lock the bootloader. But no combination of power and vol-down or power and vol-up will get me to TWRP. It just rolls right back in to Lineage.
Also, from power off, if I plug in to my Linux laptop, it will power on and go to fastboot.
Feels like USB debug got turned off and/or trust somehow got revoked, but I never had this laptop connected to it so probably doesn't matter. But like I said, my unlock pattern is working. I get different response with correct pattern versus incorrect.
I'm also able to see the phone from my https://google.com/android/devicemanager page. I tried to send a secure and erase thinking it might let me start from scratch, but I only see a notification that "Device Located" and it never does anything.
And finally, lsusb -v does see the phone, but adb devices never does.
My question is any idea how to get back to TWRP to wipe and push an updated image or even put an updated TWRP?
Try this ...
It's like getting into Stock Recovery. To get into TWRP Recovery using button combination (hard reset) you'll need to hold volume down button and power button simultaneously, releasing power button (temporarily) once LG logo appears then quickly pressing and holding power button again, all the while maintaining hold on volume down button. The stock recovery message (white background) will appear requiring you to select volume up/down button to continue to reset software (see attached image). If you select yes it will appear to factory reset but will actually boot into TWRP.
Hope that helps!

Question How to save a black brick

I tried to root my phone by magisk.
After flashing a patched boot.img, it's failed to boot into system and I got a message that "the device need factory reset". I clicked yes and everything seems ok,I can boot into system. Then I tried to flash img again. So I boot into bootloader. Unfortunately, this time I got a black screen. The phone doesn't response me anymore.
I tried the software repair in xperia companion but It cannot dected my phone when I hold on volume down and plugged in it. I also tried hold on volume up + power but nothing happened. Hold on power key also no response. The led light always black, only become red when I connect it to my pc.
What should I so now and what's my phone's status? I searched something about 9008 mode and edl but I don't know how to check whether my phone is really turn into that status, my pc cannot dect my phone.
Have the same problem, only with the 5 iii instead. Still looking for a fix.
Try to switch the phone off; then just plug it into your PC without holding the Vol- key. It has happenned a couple of times with me that the phone does not want to boot up, with attempts to get it into FLASH mode by holding the key down throwing more confusion into the mix.
I think there is a low battery protection. Make sure the phone is charged up. Keeps the device from death during a flash.
Red led mean a very low battery. Keep it plugged (not to PC but to power adapter) for 2-3 hours and then try again a force reset.
Never, never try flash or other stuff under 50% battery
Also force restart is keep pressed vol+ and power button (or vol- and power button) till you fell a vibration.
Try this after a good charge

It might require experimenting with service modes and different chargers. I had an early Xperia 1 III that bootlooped while charging after setting up the fingerprint reader. It seems that charging is disabled during booting. It has to finish or enter a service/fault mode.
my phone is having this after doing fastboot --slot=b reboot recovery (which actually I had to do fastboot --set-slot=b and then fastboot reboot recovery). the notification light blinks red. have tried vol up + power, vol down + power, and vol up + down + power for like 30 seconds and nothing

I feel sorry for you brother...such a nice device...OK let's talk what happened, the state now your device is in is called hardbrick and it had a corrupted bootloader or no boot loader, but your device is still alive, in your PC in device manager it lists as Qs USB mode with some number after it like qsusb9008...now this device can only be brought to life with the help of a blankflash file which can flash your boot loader in snapdragon service mode...actually no snapdragon can be hardbricked permanently now you need appropriate blankflash file for your device.. Please don't open the device if some repairmen suggests to do JTAG nothing is necessary all you need is blankflash file which is shared to only Sony testers groups.... Who tests ROMs before release and they hardbrick so they share those files to them.... Please don't loose hope....it takes time but certainly it can be bought back to life... And dont try any flashing utility as there is no functional boot loader on it now and nothing will work...Sony won't provide that for sure and they will say then can only solve by mother board replacement ,don't believe therm your device is perfect it only needs blankflash file as it entered into final safe mode... I ain't regular on XDA if you need any info contact me via my mail [email protected] g ma I'll .com
Have any of you tried this - https://developer.sony.com/develop/open-devices/get-started/flash-tool/download-flash-tool/
ok in my case it was the charging IC
