First of all check out this thread http://forum.xda-developers.com/zenfone2/general/guide-to-apply-ota-bootloop-rooted-zf2-t3127835. I had a problem with my phone because i rooted it, and i wanted to apply an ota so i unrooted and applied the ota, but that got me stuck in a bootloop. So i went to the thread above and did what the instructions said. Everything was fine until i started getting force closes on gapps and most apps on my phone, so i decided to reflash the system with the prerooted image from the link above. I did this and i decided to go into recovery from bootloader in order to format data as this stopped the force closes the first time. When i booted into recovery i got the same old android logo that says error, only this time it was blinking and i couldn't get into the recovery; I then force shut off the phone and tried to boot up normally but i got the same error android guy flashing again. So since i couldn't get into the stock recovery then i tried http://forum.xda-developers.com/zenfone2/general/root-newbie-root-instructions-zenfone-2-t3114063. This cwm recovery booted up fine after a minute or two. Once in there I went down to wipe data/factory reset; It completed the process and i rebooted and there was no error this time, the phone booted up normally.
If anything similar happens to someone try first the guide in the first link, then the second link if you can't get into recovery.
I hope this helped someone with the same circumstances.
@Ratedzelaya, hey, it was good of you to share your experience with all people. Btw, you required CWM to do a factory reset, right? And that factory reset fixed the phone for you, right? Well, if that's the case, you could simply boot to bootloader mode, and then issue these commands to do a factory reset:
fastboot format userdata
fastboot format cache
No need of recovery in this case, and the device should be fine as per your method. Just sharing my opinion! Having CWM recovery isn't bad anyway

That's helpful information in case I ever need it. I'm not the most familiar with fastboot or adb.

So for no apparent reason my tablet is stuck at the google logo and when i boot up twrp it is asking me for a password that I don't know. I never set up a password. Because i don't know the password i can't factory reset, flash a rom, or use adb!
Why not boot into fastboot and manually push from there?

Thanks i actually just thought to do that. I don't normally do it that way but i never had this issue so i'm gonna have to do some research but it shouldn't exactly be hard seeing as i have pushed files to my device that way anyways. Lol.

I had the same issue. I think you have to boot your device after you unlock it or something.
Anyways, for whatever reason installing TWRP thrashed your files, so you don't have a proper system to boot from.
The fix is fairly straightforward, ATGAdmin has a one click batch file that will do it for you: http://forum.xda-developers.com/showthread.php?t=2381582
That will restore your system and recovery to stock, and leave your bootloader unlocked. From there I recommend installing ClockworkMod, simply because that's what I did and it worked for me.

fastboot flash recovery recovery_flo.img

Phone was still unlocked and rooted but I had to restore everything I had added since first getting the tablet.

Just curious, and maybe a dumb question, but have you tried entering any password?
I remember with Samsung GS2 when doing ROM upgrades and changing recoveries, it would sometimes ask for a password unexpectedly. People found out they could just enter something random and it continued.

Okay i can't figure out how to flash a rom this way. I can get past the google logo if i wipe cache. I don't know how to wipe dalvik cache, and I can't find a factory rom to flash.

Yeah but it fails everytime I try a factory reset or if I try wiping dalvik cache. the mount system option is unchecked by default. I checked the box to mount it but that did nothing.
I had this issue also. I solved it by formatting the data. Seems like unless i do that, it wont mount the memory.
I had this problem trying to root two nexus 7s. At first I thought I had to unlock boot then reboot into fastboot and push twrp so I did that on my second nexus 7 but that didn't work and I ended up being stuck on the nexus boot logo. Easy fix though!! Just turn off your nexus then power it on while holding the vol up button which will boot into the android guy and factory reset your nexus. It should boot up now and then you can flash twrp via fastboot

Guys I have a big problem!
For about a month I have on the galaxy nexus rom slimkat + kernel dfk and until tonight I had not any problems, until this evening the phone has rebooted and the disaster happened, the boot animation was jerky and the phone has put more than 5 minutes to power, however going slow, and even after I have booted the phone is super slow, it's all jerky and unusable.
From recovery I tried to wipe system, but even if the message confirming correct operation, it really does not matter because if I reboot the phone loads the system, even if ever so slow and jerky.
I also tried to use the Nexus root toolkit but nothing, when I try to reflash stock hangs the command "writing system" and does not go forward ... I do not know what else to try.
I also tried using fastboot commands, but nothing changes ... not the operations are successful and the changes are not applied.
Please help me! Thank you very much!
Wipe system, cache, data, dalvik cache and internal.. Then flash stock factory image and then install roms
Wipe from recovery do not work.
I tried to flash from toolkit the stock factory image, but hangs on the command "writing system".
There is another way to flash it??
Yes..you can to flash another recovery with nexus root toolkit. Boot into android and enable usb debugging in dev. options, connect gnex with PC and flash recovery (cwm or twrp or philz, not STOCK) and then wipe..

I've tried, the procedure seems to be successful but the recovery does not really change.
I also tried to flash the stock rom with odin, well after the half-hour procedure is successful, the phone has rebooted but nothing, everything remained as before, with the old rom.
I do not know what to think anymore, I try recovery, toolkit, fastboot and odin but nothing.
I came to doubt that it may be a hardware problem with the internal memory of the phone, do not you?
Thank you!
Try to boot into recovery temporary with nexus root toolkit if you can't to flash..this can help to wipe all and brick gnex

I boot into temporary recovery and i do successfuly all wipe, but when I restarted the system, nothing has changed, loaded the old rom
I do not know what to do!
If you wiped, system can't be rebooted. I really don't have more ideas
Maybe you have problem with hardware.

My device decided to randomly encrypt itself after using the CM12 port that is available. How this happened is beyond me. Anyhow, I tried to do a factory reset... Nothing would mount because the device was encrypted. So, I thought it would be a great idea to flash a different recovery. By now, I have flashed over 6 recovery images (all different) even the stock. Fastboot says that the transfer went through successfully only to find when I try to boot into recovery, it boots into fastboot instead.
Yes the device is unlocked.
I don't know if there is a ROM on it, but when i try to start it normally, it wont boot past the splash screen (before the boot animation)
Please help, as this is the only phone I am stuck with for a long time
Here's a thread with people that have a similar problem. There are some suggestions of what to do in there, but personally none of them worked for me. I ended up having to send it back to Amazon.

Never factory restore when you have a Custom ROM as it isn't made to reset with the devices stock hardware and causes things to go crazy.
Always use a nandroid of the original system with root, then unroot, then factory restore from that.
Also. YouTube search - HTC Desire 816 root unlock bootloader.
Use the .exe recovery from that video in fastboot at least twice without exiting fastboot or rebooting.
Now try the recovery.

When you were on the stock recovery, could you wipe partitions?
Also what model do you have?
Hi, my S4 mini entered a boot loop and pressing volume up+home+power doesn't enter recovery mode.
I haven't been playing anything strange with it, it has stock rom.
I just boarded a plane, put it to plane mode and when I landed it was like this.
Please help, I don't know what to do.:crying:
Thanks
Flash stock firmware using odin.
Or you can try flashing a custom recovery and making factory reset. You will lose data but phone will recover.
Stock rom odın flash, recovery wipe data ve cache and reboot
Sorry bad for English

Thank you, but Odin is only for windows and I don't have it.
Any other program for Mac that could do that?
If possible I would not want to have the phone factory reset, I haven't done anything to justify this.
With my previous galaxy I had been playing and I could understand something similar,
but with this one I did absolutely nothing, do you understand why it happened?
I think you can not solve without turning to factory settings
Data are data without opening the phone what I will do if you can work something yok.he half of
Sorry Bad For English
Ok, I managed to get a windows PC and flashed the rom again with Odin.
It turned out that is not the problem. The problem is that after that (as much as before), when I start in recovery mode it shows the dead android and says "no command", after which it enters the boot loop again.
Now the phone has a freshly flashed stock rom, so what could it be???
I also flashed CWM-recovery and stil I can't get into recovery.
Kinda desperate now!

Just grab a latest build of any custom recovery for your device and flash it via odin.
Use TWRP or CWM latest builds. Once they flash successfully and the screen turns off
as device reboots, press and hold home and vol up keys which takes u to recovery.
Now go to advanced wipe and choose cache, data, dalvik AND INTERNAL STORAGE.
It is recommended to wipe internal storage this time. Just in case. Then reboot.
Thanks, but in which way is your suggestion different from what I just did?

Oh sorry. So it does not work even with custom recovery....
Did you try to flash it with a pit file earlier ? I mean did you do any re-partition ?
This is indeed really strange.
I tried CWM, not TWRP.
I don't know what a pit file is, I didn't repartition it, I did absolutely nothing to it.
I boarded a plane, put it in plane mode (I think) and when I landed 9h later it was off.
When I started it, it boot looped and no recovery.
Ok, now I tried also TWRP, nothing new
Does anybody have any further suggestion? I'm totally stuck and without phone almost a week now.

Better to take the phone to service center.
They will solve it.
even better I'll buy an iphone next time
I can get my one plus 3 into fastboot mode but that is it, I have tried wiping the cache and user data from there, I have tried flashing both the stock recovery and TWRP, everytime I try to boot into recovery I get a few seconds of the boot screen and then nothing?

I had a similar problem as you, managed to get into fastboot, but no recovery at all, neither stock nor TWRP. Flashing TWRP again didn't help, although process ended successfully.
Same thing for flashing the whole ROM.
What saved me from getting remote support from OnePlus was this wonderful HOW TO:

After flashing, try to boot directly to recovery by pressing the button combination.
I got it to work in the end by flashing CM recovery and then working my way from there
