[UNBRICK] white screen & waiting for device

HI all,
I've asked this question on the firmware thread, but I do not have an answer. So I'm trying here.
I installed the new firmware without any problems. But after the reboot I'm stuck on the white screen with the green logo, and I do not have connection with the computer via fastboot (waiting for device). As against the phone is communicating with the computer by HTC Sync or Windows Explorer.
What can I do?
Thanks

How did you install the firmware?
Have you tried fastboot from the bootloader?

thanks clsA
For mike's method (re-lock the bootloader and fastboot) :
1.If you are S-ON ---> Re-lock your bootloader (this will most probably wipe content of your device)
2.If you are S-OFF ---> no need to re-lock the bootloader.
3.Copy downloaded .zip to fastboot.exe location (e.g. c:/SDK/platform-tools/fastboot.exe)
4.Re-name .zip file to firmware.zip
5.Open command prompt
6.Boot your device in fastboot mode (vol down + power ===> fastboot)
7.Connect device to the PC
8.In command prompt cd to fastboot.exe location
9.Make sure you have correct modeid and cidnum (type: fastboot getvar all)
10.Type: fastboot oem lock (if your device is not relocked yet or in case it's S-ON)
11.Type: fastboot oem rebootRUU and wait for device to reboot
12.Type: fastboot flash zip firmware.zip and wait for process to complete
13.Sometimes flashing for the first time doesn't work, so flash firmware.zip again just to make sure.
14.Type: fastboot flash zip firmware.zip and wait for process to complete
15.Type: fastboot reboot
Currently I have no access to the bootloader

Although the phone is stuck on the white screen it rings when they call me

Turn off the phone holding power button for almost 15seconds till completely shut down. Then hold volume down and power button. You'll be able to enter boot loader. Also provide more details...version firmware, rom, etc

Are you flash a fw twice ?
Try to unlock bootloader and recovery again brother

I can not. The only possible action is Power and he returns on the white screen.

Yes, twice. And it was ok. I do not have access to the bootloader

You don't provide enough details. But for me it seems like you flash firmware with stock recovery and if you have custom Rom the phone won't boot. Are you sure you are shutting down the phone properly? Then hold volume down for a second. Then WITHOUT release the volume button hold down power WITHOUT release anything till I boot to boot loader?

The phone vibrates once and nothing happens. Still the white screen.

hold power + vol up....if the phone reboots...hold vol down...

[ZE550KL] ZenFone 2 Laser only has Fastboot

Hey guys, I need some expert help and guidance. All of a sudden this phone decided to brick itself and I'm suspecting a hardware fault.
I've tried all the tutorials under the sun to reflash the device from fastboot, however I am now at a loss.
Recovery [power+down key] won't start - regardless which one I try. Essentially it would write the files with [OK] messages but it never really acts on them.
The phone was completely stock MM. Is there some good soul that can guide me with reviving this phone please?
Many thanks!

Can you access recovery by pressing power + volume up to get into fastboot and then select the Recovery using the volume and power key?

yes no problem getting to [fastboot mode!!!]. From there I tried to re-flash stock boot and recovery img files and it doesn't complain - however from fastboot, booting to recovery fails (ie. power+volume down] with a black screen.
Am thinking that this might be the most viable option right now -- http://forum.xda-developers.com/zenfone-2-laser/help/links-asus-zenfone-2-laser-raw-service-t3526083

Sad day.. after running the flashall_AFT.cmd in one of the firmware files in the above thread, the processed ended with an error writing the userdata... slowly and surely, the screen faded away and the unit won't turn on at all.
I guess, this is the end of the road for my Zenfone 2 Laser

Bootloop even when in recovery mode

Hi guys,
I have a nexus 7 2013 which boot loop (or any watchdog restart ?).
If I try to normal start this one, I will get the Google logo for few seconds, then it will restart on its own.
If i press the volume down during this process, I can boot to bootloader, but same way, after few second, device will restart.
Any clue on what can be wrong ?
Thanks

Hello, connect external power and try again. If it works now, you will have to replace the battery.
If it does not work with external power and it can not stop in bootloader/fastboot mode, then the hardware is faulty or the bootloader is corrupt.

External power does not change anything. Still boot loop, so really should be a hardware issue.
If I keep volume up key pressed, it boots, but almost unusable if I have to continuously press the volume up key.
Same when in bootloader: if I continuously press the volume up key, it does not reboot.
I've tried to erase everything with fastboot, but cannot do most of the operation. When trying to format data, it says that partition does not exists (it exists, as it can boot !)
Bootloader is locked, so cannot go with TWRP for example, as I cannot validate the on screen confirmation needed to oem unlock.
Do you know any way to unlock bootloader without use of onscreen confirmation ?

I don't know if that would help, but when I was installing Lineage OS and updated TWRP, I also boot looped once on recovery (recovery itself was boot-looping), and re-downloading (from another browser) and re-installing recovery at fastboot mode fixed my issue.

I cannot unlock the bootloader because of this issue, so cannot flash anything

Could be broken power button, if it is stuck and pressing it continuously.

Are you able to reach your recovery to factory reset?
I mean can you reach it from the bootloader menu?
If not you could try to put twrp.img or recovery.img into your PC adb&fastboot folder and try
fastboot boot twrp.img
or
fastboot boot recovery.img
Don't know if this works with locked bl
Edit: may type
fastboot getvar all
and post your result, hide your imei if you got one

can't get into recovery mode

hi
i just unlocked my mi5s now, but when im trying to get into recovery mode (volume up + power) it still shows me the phone picture.
there is something that i am missing?

Flash the recovery, when in fastboot reboot into recovery by "fastboot boot recovery.img" if that's the name of the file on your computer. It will boot into recovery. After that, turn of the phone and boot into recovery with the button combination. Do not boot into the OS as it will disrupt the process! After this you should be fine. If not, try again, as you probably failed to directly boot into recovery with the button action.
Also, do check that you push both the volume keys plus the on/off button. So three in total.

as far as i know, when im unlock the phone, it unlock the recovery mode so i can access it by volume up + power instead of the phone picture.
i want for now stay with the stock recovery and not flash a custom one

Mm, you could use the phrase "fastboot reboot recovery". If that doesn't work, flash the latest Global beta and try again both ways.
If that also doesn't work, recheck if the phone is really unlocked (sometimes Xiaomi phones relock after an update without any good reason).
You could also try to find the stock recovery and use it in the method in my first reply. But keep that for last, as I don't know for sure how that recovery reacts to such a thing. Although I can't think of a reason why it would go wrong, it's better to be save than sorry.

Phone might be bricked. Need help to find a solution!

Hello everyone! Complete dumbass here!
I was following the guide to root my razer phone. I've had it for a couple months, and decided to root it. I followed the guide here https://forum.xda-developers.com/razer-phone/how-to/twrp-magisk-fullproof-guide-razers-wifi-t3756137
After a couple bumps in the road, such as fastboot commands not working, not being recognized, etc. I finally was able to unlock bootloader and install twrp. But it was #9 that got me stuck again.
"9.) Once in recovery, go to the install button, and select Install Zip, and select Magisk-v16.0.zip."
In recovery, adb devices and fastboot devices yielded no devices attached. Doing a search, I came across another forum post where it states the sdcard is encrypted and can't be accessed in twrp, and the fix is to do something like "Wipe>Wipe Data> Type Yes" and that should factory set the card. I did this and rebooted the device. I waited for a half hour for the animated PixelFloatingInACircle logo to be done with it's floating in a circle, but ended up going to bed and letting it die. Woke up this morning, plugged it in, got the razer logo splash screen with the orange text telling me of my impending doom, then went back to the animation. I let my dog out and came back and it was still on. I unplugged it and am letting it die again to see if there's another solution.
I'm wondering if anyone else came across this issue, and if so, how did they fix it? Any help would be appreciated.

Use the factory images in the developer portal. You have to manually install the fastboot driver or you won't see the phone in fastboot devices. After that you can flash_all.bat.
PS: if you just want root you can use magisk installer to patch the boot image (from the factory images) and then flash the patched_image.img. That's it, now you have root via magisk

The problem is when I try to enter download/recovery mode after charging the battery a little, it doesn't go to that menu. Instead, it skips right to the particle logo, and that's where it hangs.
The only guide I saw was the one I listed. Is there a guide for this magisk installer?(Ya know, in case I figure the first problem out, so I might try my hand at potentially creating another)

i think there is a way to hard reboot the phone, so you can do that and then hold the vol- key to start in bootloader mode when it reboots.
gonna check the correct buttons.
Edit: the button combination is power+vol+ for about 10-15 seconds, and the phone will reboot. You have to connect the phone via usb cable (before rebooting) to the computer (the only thing i'm not sure is if you have to have the fastboot drivers in the pc installed previously or if you can do it after entering fastboot) and just after the screen goes black while hard rebooting you have to release all the buttons and then press and hold the vol- button. The combination of vol- and the usb cable on boot seems to trigger fastboot mode.
I think the guide is in the guides forum, but the way it worked for me was without twrp:
- install magisk manager from this link -> https://github.com/topjohnwu/MagiskManager/releases/download/v5.7.0/MagiskManager-v5.7.0.apk
- push your boot.img (the easiest way is getting it from the factory image corresponding to the firmware you are using) to the sdcard
- open magisk manager -> install -> patch image only -> boot.img
- this will generate a patched_boot.img in /sdcard/MagiskManager
- copy that file to your pc
- go to fastboot and flash that patched image: fastboot flash boot patched_boot.img
- enjoy root, and you can use magisk hide for apps that don't like root

Tried this originally after I let it die the first time. It still boot to the animation logo.

Read the edit, I found that the trigger is having the usb cable connected to the pc. Try that, or you can also try to adb while the device is booting (particles logo). Sometimes adb is responsive even when booting. There you can try to adb reboot bootloader

Progress! Got it into download mode. I have the boot.img I got from razer, should I push that and see if it boots normally?

As you already wiped the data partition, you should use the flash_all script. But yes, you can try flashing each partition

I moved the flash_all script into the tools folder and after a little while, the phone booted up into setup! After a couple taps, I've realized the wifi isn't working, which I know is a known issue. I'm gonna let it sit for the night and finish it in the morning!
EDIT : Soooo, I know I said I was going to bed, but I decided to fix the wifi issue, which in turn, also rooted my phone. I've downloaded the root checker, and it confirms it! Thanks so much Waiflih! You rock!

Hi guys, it seems I'm having the same problem and basically after unlocking my bootloader and flashing twrp to both of my slots I'm stuck on "Your device has been unlocked and can't be trusted" booting up infinitely.
The USB plug in and holding the volume - button doesn't bring up "download mode" and no matter what buttons I try and press on my phone my computer doesn't recognize ANYTHING connected to it anymore.
Bloodeagle, how did you manage to get "download mode" back onto your phone? it seems like mine refuses to do anything like download mode.

Have you tried holding few combinations of different butt9ns for a minute or two to see if that results in you getting in downl9ad mode?
