If you can enter fastboot, flash latest twrp recovery, nuke everything and sideload a rom/put a rom in external sd and flash from there... Should work...

Hold down the power button and the vol. up button for 20 seconds or so.
As soon as it goes dead, switch from vol. up to vol. down.
Fastboot is where you are now.

hi! well, to flash recovery it's plenty of tutorial around, and you can look on twrp official site too... to delete everything, just select full wipe in recovery and to sideload follow this guide http://teamw.in/ADBSideload

Bricked Nexus 7 while installing Lollipop - fastboot kinda works

Hello.
So I tried to install Lollipop on my Nexus 7 2013 WiFi. I used their official instructions developers.google.com/android/nexus/images . Before that I made a backup in recovery (if something went wrong) and wiped data. So I did all that and tried to install Lollipop using their instructions, but now after turning the device on I see Google logo and that's all. Also recovery doesn't work. It just shows dead android. Fastboot works, but adb doesn't see my device now.
Before this I had Clean Rom installed.
EDIT: I can see it using fastboot, but it f'd recovery.
EDIT2: I used flash-all second time and now it works, God, for a moment I thought I lost my baby.

Just restart device to bootloader, unpack official Lollipop image and run flash-all.bat within directory with fastboot.
It's very difficult to hard brick..

FWIW adb only works when booted into Android. Fastboot only works in the bootloader.

Just download wuzwigs Rom toolkit and revert back to kitkat and start over. Ive had moments where i could barely get fastboot to work because my freaking power went. Just run through that and follow the appropriate steps and try again... Or just wait for the official update next time. It cant be more than a few days away now

Nexus still in mortal peril

My problem is I tried to unroot in order to flash the update to lollipop and now unfortunately I seem to have actually hard bricked the device. I can boot into the bootloader. My device is still ulocked. However when I try to access recovery I get the dead android icon. I tried reinstalling adb. It didn't take. I can't get device to show up in the command line. I tried reinstalling drivers and that's where I'm stuck. I can't seem to make this work. Even if I can just go back to 4.4.4 I'll be happy. What are my other options that don't involve sending it in for repair?

I accidentally wiped my internal storage and my operating system this weekend! Mskips toolkit is the only one i could find that would install the drivers properly and then flash a factory 5.0.1 image... Everything works great now!!

The problem is that I can't boot up. Which means I can't put the device in ADB mode. Which means I can't use the skipsoft tool kit.

Use wugs but make sure you tick tablet is in bootloop, worked for me.

U can't boot in to android, but u did state earlier that u can boot to the bootloader, and that it was unlocked, so its definitely not hard bricked!

Soft bricked

Hello everyone, today I installed TWRP recovery, it went fine and I am not new to install custom roms, custom recoveries, etc. but this got my phone messed up. It was working perfectly fine and then I turned it off in the night and in the morning, it just got stuck in a bootloop, and knowing me of course, I forgot to create a backup as I installed TWRp. So, is there any kind fellow out there that has a TWRP backup at hand for the ZE551ML?

Just to get the order correct...
Flashed TWRP - No problem
Rebooted to system - No problem
System worked?
Turned off phone
Bootloop on power on?
Is this a bootloop, or does it just sit on the Asus screen? Does it get to the actual boot animation, or are you on the splash screen?

I am getting to the boot animation with the gears turning and then error comes up and boots me into TWRP. The problem is, the Bootloader will not come up so I can do the fastboot flashing, TWRP comes up instead. It comes up and I didn't overwrite the bootloader with TWRP. Problem is I can't access fastboot commands.

Give me a few minutes. I'll get you a TWRP flashable boot.img zip.

Try flashing this in TWRP. You might need to sideload it onto your phone if you can't boot into system.

Thank you. But, it won't flash, I've tried about every option now. I think I'm just going to see if I can get a replacement. 2.19 was always causing me problems to install and then now that I finally got it on my phone, I couldn't install another 2.19 on top of it or downgrade. Guess this phone is done for until CM12 gets released. Thanks for the help but it seems it can't be recovered at this point.

If you lurk on these forums, there are some Intel flashing tools I've seen that can help you recover from a soft brick.

I am stuck too!
I was in stock recovery and did a cache wipe. It took forever and wouldn't come out of it so i powered it off and tried booting. It got stuck on bootloop. phone is asus zenfone 2 Z00A. It is intel chipset. please help me out.
the worst part is that i cant get into fastboot or recovery modes so i am completely stuck! please help me out.
when i try to get into fastboot mode with vol up+ power key it vibrates but nothing is displayed.
if i just power it on its stuck on bootloop.
i can't get into recovery and fastboot bcoz its at the same place.
can i use adb commands or fastboot commands somehow?
i can maybe use adb reboot recovery to get into recovery and then i can do a wipe and flash new stuff.
please help me out.
UPDATE: I found out u can use adb reboot recovery while on the asus bootanimation.
i tried adb reboot recovery and now getting a flashing android sleeping bot with error!
can't use adb or fastboot commands now though
now in even bigger mess. after using adb reboot recovery, i can't get to bootanimation either.
just stuck at flashing android sleeping bot with error.
can't get to bootloader or fastboot or anything!
Please any suggestions. I'm dying here to fix it.
I have a adb backup.
i couldn't take a nandroid backup. i just entred recovery and wiped cache first. after doing that i was going to flash twrp and then using twrp take a nandroid backup and flash a custom rom. but it got stuck at cache wipe and i powered it off and the whole mess.:
Finally entered bootloader with fastboot now working!

how did you get fastboot working? I can get into bootloader, but cant get my pc to connect with my zenfone2. can't use any adb cmd it would just say "error: can't find devices"

Just a reminder to everyone, never force shutdown the Phone during a cache wipe procedure, it takes a long time but it finishes.
When I did it on my ZF2, I thought it was taking too long, but I did a search here and found out about it taking long before it was too late.
I'm glad you could recover yours. :good:

I shut mine down because it took too long. Wouldn't start up again. Had to send it in for RMA. Asus Canada reset the OS. I'll never do that again.

Dude you can never use adb when in bootloader.
That's why you have fastboot.
just type
fastboot devices
you will get your device.
if you don't then download intel drivers. You will get them in asus website.
if you are stuck without custom recovery i would suggest you to download system image (~1.5Gb) from asus website.
just search for asus zenfone 2 and go to official asus site. in downloads tab you should find both drivers and system image.
download the latest one.
See if you can get into stock recovery.
when in bootloader press vol down and go to recovery mode.
you will see a sleeping android bot with error.
press power key + vol down you will get a list.
choose factory reset and then after wipe is complete choose sideload from adb.
connect your phone and then in adb type
adb sideload filename.zip
obviously place file in your platform-tools folder and replace filename with whatever its name is.
it will take a while and you will get back your system.

It took a lot of time though.
For anyone stuck,
I first got fastboot working. and then i flashed stock recovery and boot.
got into stock recovery and sideloaded system img into it.
After it booted back into asus stock rom i unlocked bootloader, placed twrp in sdcard and got straight into fastboot again installed twrp and then did a wipe and went ahead and flashed ROM and Gapps. Working fine.
Update:
To get to bootloader:
i was stuck in a bootloop.
When at asus boot animation i connected USB cable and quickly typed
adb reboot bootloader
which seemed to work for me. Though i couldn't get into recovery.
So i had to flash stock recovery again.

Phone bricked?

Sorry posted in general by mistake:
Some info,
I unlocked the bootloader and installed twrp.
I restarted the device and everything was working. I then entered twrp but I forgot to place supersu binary on hte device so I thought to use adb sideloading to get it on...
Thats when my phone got bricked. It failed (saying something about adb server wrong version then adb client);
I disconnected my phone but now it wont turn on/off, charge or do anything.
Any ideas? I tried charging it, tried going back into fastboot but no response.

When you charge it using a DC adapter, does it blinks red light?
Or, does the computer show anything when you connect your phone to it via USB cable?

Ok after waiting a long time (i presume draining the battery) and recharging the phone I can acces the twrp recovery. However I cannot start the phone itself, it always boots into recovery.
Thinking of ways to fix my phone i flashed a rom (from here) to see if that fixes it but it still only boots into recovery.
Any ideas?

Yes. Recovery is the only thing that works. I hold the three buttons at the sane time and it boots iqnto twrp. Reboot system, reboot bootloader doesn't work. It just boots into recovery again and again.
It all happened when I was taking the backup of the stock ROM. The recovery had some bug which prevents it from turning on the screen after screen timeout. Then it was bricked.
I didn't try flashing any rom zips, since there's no ROMs for this device and I can't find a stock ROM anywhere.

Recovery boot loop occurs whenever you reboot directly to the recovery. Always boot to recovery from fastboot (menu) and you can avoid recovery boot-loop in future.
Anyway, what is your device model...OS build..Lollipop?

Hello guys, I was attempting to flash TWRP and now my phone is bricked. I've been searching through the treads but I cannot find anything that can help.
My computer recognizes my phone as "fastboot nash S" Any help with this would be greatly appreciated. Here are some pics of the screen.
One screen says, "Start up failed: Your device didn't start up succesfully. Use the software repair assistant on computer to repair your device.
Connenct your device to your computer to get the software repair assistant."
Ap fastboot flash mode (secure)
no bootable a/b slot
fastboot reason: fall-through from normal boot mode

Flash all back to stock and try again. @joemossjr and I haven't been able to replicate that issue as of yet to TS further. We both flash all back to stock and tried both boot a and boot b flashing and have no issues.
