Fastboot Reboots Normally Abnormally. - ZenFone 2 Q&A, Help & Troubleshooting

Hi, I am having an issue with my Asus Zenfone 2. The title says it, it's pretty normal, but at the same time it's not normal. I have been trying to flash a recovery in fastboot mode, but I can't. Once I get to the fastboot screen, it starts counting down seconds from 5, and it won't let me flash/send the file successfully, and my phone simply turns off and turns on normally, a normal reboot.
The only problem is that, it doesn't stay in fastboot mode, it restarts in 5 seconds after you get to the fastboot menu.
Does anyone know what can I do to fix that? I have no clue why it does that.
Thanks

Anyone? :/

HTC 10 stuck in fastboot

I am stuck with bootloader. Couldn't not enter recovery. Flashing from bootloader again and again didn't work. Couldnt enter download mode either. It goes into download mode then starts restarting. Tried RUU, it says low battery. When tried power off it and put to charge, charging icon comes and then restarts again and again.

Phone boots slowly in fastboot and canno't do hard reset!

Hello,
my friend gave me his HTC Desire 816 to fix it. Phone originally boots up in fastboot mode, but very slow and unresponsive. To describe it, when I push the power button to turn it on, only after 30 seconds the androids on skateboard image shows up and it takes approx 20 secs to get in fastboot. Then again, it has laggy menu in fastboot and I tried to do factory reset but after hitting it, it only shows androids on skateboards again only for few seconds then just turns off.
Phone has bootloader locked and It canno't boot normally.
Please help me and my friend.
Thanks community, you are the best!
Bump!
Try the htcdev unlock process and see if it works.
If so you should be able to put twrp 3.1.0.0 on it.
You can also try to
fastboot boot recovery.img
Replace recovery.img with whatever the exact filename is for the a5 twrp

Boot loop issue: cannot get into fastboot from "no command" screen

Hey everyone,
A2 lite phone is in bootloop - allegedly (not my phone) "out of nowhere". The user does not do any fancy things like flashing, and this has not been done either.
Phone is on continuous boot loop, and sometimes (really seems randomly), the device starts up in the "no command" mode and stays there for a while. I read that we could go into fastboot mode by pressing "power button and tapping volume up key", but this doesn't do anything.
I've tried this thread: https://www.the***********.com/boot-xiaomi-mi-a2-fastboot-mode-recovery-mode/
But I'm not even getting into fastboot.
I'm almost thinking that the volume buttons are just broken, though from the feedback of the buttons this doesn't seem realistic.
EDIT: ok, now I'm somehow able to get it into fastboot.... sometimes. Now I'm here:
I switched the partition from a to b, but it still goes into bootloop. Then I switched it back to a, still bootloop. Then back to b. Still bootloop! But at least now sometimes I'm able to get into fastboot. No matter what kind of commands I'm typing in the cmd console, after about 10 seconds on the fastboot screen, the phone just reboots.
idk, it looks almost as if both partitions have the bad android 10...
Do you guys have any idea? Please let me know if more info is helpful.
You go into fastboot mode by holding Vol Down + Power button. So try holding Vol Down and Power button at the same time to go into fastboot mode. (Don't tap it)
Go here and grab the image you prefer (latest should do the trick) : https://forum.xda-developers.com/mi-a2-lite/how-to/fastboot-xiaomi-mi-a2-fastboot-images-t3824871
Then go ahead and follow this guide here to flash the stock ROM : https://c.mi.com/oc/miuidownload/detail?guide=2
This will wipe the data on the device, but it seems like you have no other option at this point. Cheers.
Thanks! I've tried that now. It starts flashing the device until... after about 10 seconds, the phone reboots from Fastboot mode .
As per this page: https://twrp.me/xiaomi/xiaomimia2lite.html
I've tried to do a recovery via TWRP. If I execute `fastboot boot path/to/twrp.img` then I go from fastboot to TWRP (the teamwin logo), but right after that the phone already reboots.
https://www.xda-developers.com/how-to-install-twrp/ - I don't know if it means anything, but when I execute `adb reboot bootloader`, the console returns `error: no devices/emulators found. If I execute `adb devices`, it does not list my device. However, if I execute `fastboot devices`, my device is listed.
I installed ADB usb drivers, so when I get my phone connected in fastboot, it shows up as Android Bootloader Interfacee in device manager. So not sure what's going on here, but it's all weird.
What I'm facing is very, very similar to https://www.reddit.com/r/Xiaomi/comments/4ltzt9/xiaomi_mi_note_boot_loop_even_in_fastboot/ <-- but that thread is a bit of a dead end (and 3 y/o)...

Hmm, it should never do that, maybe it's a hardware issue that we can not fix via Fastboot ?

When the device is in Fastboot mode, it will only be recognized as Fastboot. Only when it's properly booted, the device can be recognized in ADB, so no issues there.
I assume your bootloader is already unlocked as you have successfully booted into TWRP. You might try EDL (Emergency Download Mode) flash as a last resort :
Download MiFlash (20160401) from here : https://www.xiaomiflash.com/download/
You're downloading that particular version because it is able to EDL flash on your phone. Install the MiFlash you've downloaded and open it, then put the phone into fastboot mode. Connect it to your PC and use this code to take the phone into EDL mode:
Code:
fastboot oem edl
After you hit enter, you will see the screen turn off and notification LED blinking, this is normal. This means the phone is in EDL mode. Open the MiFlash you've installed (likely in C:\Program Files\Xiaomi\MiPhone) and browse to the ROM location and connect the phone. Choose "Flash All" and start flashing.
After the EDL flash is complete the phone will not reboot. It will stay in EDL mode. You need to disconnect the phone from PC and hold power button (about 10-15 seconds) to boot the phone. If the phone boots properly, you can go into fastboot and connect it to PC, then use:
Code:
fastboot oem lock
to relock your bootloader. Try it and let me know. :fingers-crossed:
Thanks for the continued help!
I've followed your steps - When I run fastboot oem edl, the console returns "... okay [ 0.0202s] finished. total time: 0.022s" and the phone turns to a black screen (no notification led blinking). Then... after a couple of seconds, goes back into the boot loop .
Something maybe to note: every time that my phone starts up, it (1) shows a screen saying "Your device software can'tbe checked for corruption.Please lock the bootloader.", and then slides down to the typical "androidone" white screen before it reboots again.

The screen with the ugly text is normal, since you have an unlocked bootloader, it's there to warn you that the device's software might've been tampered with. On the main subject though, I'm out of ideas. You might try booting the phone by holding Power + Vol Up, which should normally boot into stock recovery or wipe the data on the device. But I'm slowly beginning to think that this might be a hardware issue rather than a software issue that I can help you to fix.
Under normal circumstances, EDL flash is the way to fix any problems you might encounter with the software, that's why it's called the Emergency Download mode. But since we're past that stage, I believe I will not be able to assist you further. Hope you can fix your device my dude/dudette!
If the phone gets out of fastboot mode your phone does not get recognized from your computer. Try to delete fastboot and minimal adb and download the latest version. [https://forum.xda-developers.com/android/general/tool-adb-fastboot-installer-tool-windows-t3999445]
Open MiFlash, click Driver left on the top and install them.
Set path to the downloaded firmware. Now boot into fastboot, once that is done connect your USB cable to both, computer and phone. If this doesn't work try different USB-Ports and USB-cables. Some work, some don't. This might be the reason for leaving the fastboot mode.
Click refresh and see if your device appears
@marstonpear thanks for your help so far <3 @Cappucinto, thanks for chiming in! What do you mean with this: "Open MiFlash, click Driver left on the top and install them." <-- in MiFlash, I do not see an option to select driver...

 @Cappucinto, thanks for chiming in! What do you mean with this: "Open MiFlash, click Driver left on the top and install them." <-- in MiFlash, I do not see an option to select driver...
What did change now after installing these drivers: https://forum.xda-developers.com/android/general/tool-adb-fastboot-installer-tool-windows-t3999445]
I did try some other USB cables. The one I've been trying triggers the windows sound for "new device successfully connected" when I boot the phone up in fastboot, and then of course gives the "device disconnected" sound when the phone then reboots. With another USB cable in this case, windows just states: "USB device not recognized". So it seems like the cable I haven't been using is defect .
I'm unable to use MiFlash at the moment so I can't explain the whole procedure with installing the drivers in MiFlash. But there has to be something like "Install > Drivers" or something. Maybe someone else can help out.
Try to use the working cable again, open a command prompt and type: fastboot devices
Then wait for an answer, post it here and see if the phone reboots again or if it stays in fastboot

Although u shd consider this link, i tried to arrange it step by step:
https://forum.xda-developers.com/sho...php?p=79365091
Follow the instructions, as dat was how i revived mine. Hopefully it may help u.
Note; wen using twrp, preferably use " twrp - offain "
Miflash tool:
Link 1: https://www.xiaomiflash.com/download/
Preferably use Link 1 & choose either 2016, 2017 or 2018 versions. They come preloaded with the drivers u need
Link2: https://xiaomibuzz.com/downloads/download-xiaomi-mi-firmware-flash-tool-latest-version-2018.html
Lets know how it goes

Hey there When I get into fastboot and run `fastboot devices`, a code returns <tab> fastboot.
... and then the phone restarts I'm trying but I guess I'm beyond the stage of being upset, haha.

remember to use "twrp offain for daisy". It works better than the regular twrp for daisy
It my take and procedure that worked for me at the time. Good luck tho
Thanks! Sadly, when I get to the `fastboot oem edl` step, it fails. I get into fastboot, I quickly enter `fastboot oem edl`. CMD says finished, the screen turns off. I immediately refresh in MiFlash (COM3 is the device), I start flashing. After 4 seconds, the device turns off (windows sound "device disconnected"). The flashing runs for a total of 7-9s says "the operation completed successfully.(0x000000000: cmd <?xml version="1.0" ?><data .. etc etc
So I don't really know what to do if I can't get into EDL mode .

Try getting another chord and try again.
Tried some other cables. Every time I run fastboot oem edl, it keeps saying "finished", and then reboots the phone in about 5 seconds. One time, it said "Catastrophic failure" as "status" for the flashing.
Otherwise, it most often says "The operation completed successfully.(0x00000000: cmd <?xml version="1.0"?><data><patch SECTOR_SIZE_IN_BYTES="512" byte_offset="16" filename="DISK" physical_partition_number="0" size_in_bytes="4" start_sector="NUM_DISC_SECTORS-1." value="CRC32(NM_DISK_SECTORS-1.,92)" what="Update"/></data>)
But then still continues in the bootloop...

Bootloop and cycles out of fastboot

I'm running a Redmi note 8 pro (MIUI 12) global no custom ROM or TWRP.
My phone recently shut down and went into a boot loop, I let it die out and It didn't solve the problem, and disconnecting the battery didn't either. I tried fast boot and recovery but recovery (VOl+ and Power) did nothing and just cycles, fast boot loads in waits 10-15 seconds then cycles the loop again. I have access to a computer I'm currently running Linux (Manjaro) and have ADB working if for whatever reason id need windows I have a dual boot available. any help or even spitballing is appreciated (First post) thanks.

Flash full same version fastboot rom (don't downgrade) by fastboot. You'll need to unlock your device.
You'll probably need to use Windows.

Kicks me out of fastboot after 5 seconds. The phone is unlocked. restarting fastboot as soon as it closes got me 30 seconds at most but I'm sure that isn't recommended.

If I remember correctly fastboot reboots some time after no commands. Did you try command "fastboot devices" to verify it's properly connected? If not, it's a driver issue. It's been a pain in the ass for me to have correct fastboot drivers installed even on windows 10 with ADB drivers working.

Question Stuck on "Wiping, please wait" screen whenever I turn on the phone

My Oneplus 9 Pro boots into the wiping screen every time I turn it on/reboot. The progress bar goes to ~99% and then sits there seemingly indefinitely. I am able to boot to fastboot screen, but if I select "START" or "Recovery mode" the phone reboots and goes to the "Wiping, please wait" screen and again gets stuck there.
I can connect to the phone with fastboot.exe from Windows.
How do I get out of this loop?

Use MSM Tool to flash your ROM again. It's here on XDA, look for it.

Thank you. I finally figured out that to get into EDL mode, you need to press the VOLUME UP+VOLUME DOWN for approximately 40 seconds, but NOT the power button. The phone screen will stay black and provide no indication that anything has changed. Then connect the phone to the PC and MSM Tool will detect it and I was able to successfully restore the phone to working state.

Actually, when you turn off the phone, you just hold BOTH volume buttons and connect the cable (PC), and takes like 2-3 seconds to enter EDL mode.
