[Q] Cannot get out of boot animation nor flash by odin or fastboot - Help please

Hi everyone, I'm new here and I have a GNex on my hands.
While I received it to fix; I could not get it past a bootloop from the nexus 4.0.4 Boot.
Problem is I cannot seem to get past the boot animation screen nor upgrade it.
Tried flashing another bootloader via fastboot, and the bootloader does not change, stays in same version.
HW Version : 9
Bootloader version : PRIMEKK15
Baseband version : I9250XXKK6
I proceed doing a fastboot erase bootloader and trying another bootloader, rebooting into another bootloader but no luck
Tried also ODIN flash but no luck; stays into the same
Booting into recovery mode goes into stock recovery and tries to flash a file from /cache
By trying to flash CWM via fastboot flash recovery <cwm image> flashes image but no luck on booting into CWM.
Anbody can lend a hand please?
Thanks!

You can flash a custom recovery like cwm or twrp. Then you can acces the custom recovery and adb push your ROM and gapps. Then you do the wipes and flash the ROM and gapps. If you dont understand anything you just have to tell me

Thanks mrgnex. I've tried flashing TWRP, but the only thing it does is boot into stock recovery and tries to flash a file from /cache/, which file is: 5a81769b6d01.signed-yakju-IMM76I-from-ICL53F.5a81769b.zip; pretty weird. Issue is the same as this thread: http://forum.xda-developers.com/showthread.php?t=1909331&page=4

use: fastboot boot recovery.img

and "recovery.img" which recovery do you suggest? twrp or a CWM in particular?

doesnt matter. whichever.

While now I'm trying to install latest TWRP (already did and no luck) I'm downloading the pack from the "Have you read this?".
The things that I'm seeing right now that seem to be wrong are:
1 - everytime I reboot the phone, the "fastboot oem unlock" seems to be gone and phone re-locks again (weird!)
2 - every change I make to the filesystem, seems to be non-persistent I/E: push something via adb push and on reboot it's gone! :/
Any help would be greatly appreciated.

Can you elaborate on why exactly you were not able to install TWRP?

Surely:
1 - Unlock via fastboot oem unlock
2 - fastboot erase recovery (exits with ok)
3 - fastboot flash recovery twrp_versiondoesnotmatter.img (exits with ok)
4 - reboot w/power+vlup+voldown and select reboot recovery
5 - stock recovery appears
an alternate method that i've tried:
1 - Unlock via fastboot oem unlock
2 - fastboot boot twrp_versiondoesnotmatter.img (exits with ok)
3 - TWRP boots and flashes a zipfile from /cache/ then reboots automatically
That's what happens. A mistery, huh?
Also I've tried OMAP Flash, and; the same issue happens over and over again

Have you tried doing a factory reset using the stock recovery?

AFAIK, Yes
What happens once I start the stock recovery; as I've already stated; starts flashing a zip file located into /cache/ (5a81769b6d01.signed-yakju-IMM76I-from-ICL53F.5a81769b.zip); then bleh, starts the bootloop again.
I've tried the power+volup then selected wipe cache and wipe system and it's the same.

Did you try flash google's stock images (all of them) ?
Also try flashing TWRP in the boot (kennel) partition by :-
Code:
fastboot flash boot <path to twrp>.img
This will force the phone into Recovery (But you will have recovery bootloop , can be solved by flashing a kernel) .
when you boot into recovery install a Kernel and ROM . also you will lose the recovery after that .
You can flash the TWRP from the TWRP itself (to put it in the right partition) by (in the build in terminal) :-
Code:
dd if=/<path to twrp in SD>.img of=/dev/block/mmcblk0p8
Good Luck .

fastboot flash boot <path to twrp>.img does not boot the recovery . I mean; still boots the normal Kernel.
Actually I'm trying what TheMysteriousOne told me by downloading the stock Gnex zip (250Mb) to flash via Odin.

Ohh, bad luck strikes again:
<ID:0/011> system.img
<ID:0/011> Complete(Write) operation failed.
cannot write system.img :/
Any ideas?

Unlock your bootloader with omapflash. Although even if it does unlock, Your emmc/board probably has died.

can you please me guide how to do the omapflash?
I've downloaded a file called OMAPFlash_tuna.zip.
- Set battery of the device aside
- Plug device into USB, let it detect the device and flash the SBF I think.
That'd be all?

Pardon me, if EMMC/Board is dead; why does it boot or get into bootloop? There is something that reflashes itself; it even overrides odin or heimdall...

Have you tried going back to completely stock using the method outlined here? http://forum.xda-developers.com/showthread.php?t=1626895

[Very serious]Non-booting/non-changing/not working problem

I woke up today to a bootloop. After pulling out the battery, I cant turn it on, it was stuck at the google logo. I thought it was some rom issue or something. When I had the time, in the afternoon, I just boot to recovery, and wiped data+sd card. Turns out sd card was not wiped.
Just now, I found a way to boot it. (AFTER WIPING DATA) I used the gnex toolkit and boot with insecure image, and guess wat? My old rom boots. Everything was the way it was, and then it crashed and stuck on the google logo again.(I made sure i wiped things two to three times, data and sd) I did a few experiments:
1) Flash using ODIN
2) Flash CWM using toolkit--it changed back to twrp after reboot
3) Changing the icon on my homescreen after boot--- everything was the same again after booting
4) Flash stock image using toolkit
5) Wipe data using manual adb
6) Try to lock my bootloader
Everything I tried changing, change back to the original state after reboot. What is the problem?
Device: Galaxy Nexus
ROM: Purity 7 sept release
Kernel: Fancy r42
Logs in twrp are showing updating partition, not FAIL. So I really don't think there is a need to show the recovery log.
HELP ME!

are you flashing your recovery or just booting the recovery?

Oem unlock will unlock your bootloader and wipe the internal storage in the process. I saw you didn't use fastboot. You could try that. Flash the Factory image via fastboot. If that fails try omap flash.

Yup,I tried it already thru toolkit. Not working either.

Dude the toolkit blows, flash back to stock manually via adb command prompt. There are tutorials around here on how to do it. It's guaranteed to work if you don't screw it up.
Honestly flashing back to stock via adb should be something everyone should learn if you plan on flashing roms.

[Q] Can't enter recovery Verizon m8

Hello guys, I've had a problem with my phone since flashing 5.0 firmware months ago but I'm just now getting to fixing it.
I have twrp recovery and some 5.0.1 rom that was in beta awhile ago. Everytime I boot into twrp in boots right into fastboot, whatever it's called, after about 5 seconds, so I can't flash any roms, which I think is the problem since it's pretty buggy.
Another thing is that Whenever I charge the phone while it's off, it boots into bootloader and therefore stops charging. Anyway I can fix my recovery without recovery?
This is Verizon htc one m8.
Thanks guys.
Edit: tried using twrp app to reinstall recovery but it boots into bootloader instead.

Of course there's a way. Just like the way you first installed a custom recovery. I will give you instructions in case you've forgotten, or if the phone was pre-rooted when you got it.
Download the latest TWRP from here onto your PC.
When the download is finished, rename it to recovery.img and place it into your fastboot folder.
Hook up your phone to your PC, get into ADB/fastboot, and issue the command fastboot flash recovery recovery.img
Then when it's done fastboot reboot
You should now have a working TWRP recovery.

Had to use my brother computer and set it up since I got a mac. Thanks for your reply, and sorry for the double post, I installed via fastboot, and I can confirm the most updated version was pushed to the device, but it still goes right into fastboot after booting into recovery.img
Edit: Did that fastboot erase cache thing in the command prompt and now it works. Thanks for telling me the commands for cmd again!

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.

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.

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.:

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.

[Brick phone] help needed

I have flashed many phones before my G4 and this is the first time I'm having to ask for help.
The firmware installed was AICP CM13, then the screen went green with a DemiGod message. I held the vol down button to reboot and it came back up. After a few restarts and green screens i figured I needed to reflash the firmware. I booted into Recovery and while wiping the device to flash a new firmware, TWRP crashed. After leaving it for half hour or so, I took the battery out to enter into TWRP so I can flash the new firmware. TWRP is no there to be seen. I hold down the vol down and power button, releasing power for second or two and choose to go into recovery. Every time the phone just gets stuck on the LG screen displaying "Bootloader state :Bootlader unlocked!".
In short, I have no firmware, the device has been wiped and TWRP doesn't seem to be working.
I have tried to flash a KDZ file (H81520A_00.kdz) using the flash guide here. This comes back as unsuccessful saying "connection to server failed". As shown below.
View attachment 3605673
The method to flash an .img file using cmd on the pc includes moving the 4gb .img file to the parent folder of the phone storage. I can't get to move any files whatsoever to my device so figured this method would not work.
Seems if I can somehow flash TWRP, then I should be able to install a new firmware.
Any help much appreciated.

Hi, Can you get an ADB connection to your phone, or get your phone into bootloader somehow. From there you could try 'fastboot boot recovery.img'?
If so, then from within TWRP you can flash twrp recovery so the recovery is then sorted. Then you could flash click here (the full version). This will then allow LG UP to find a connection. From there if you really wanted to can flash any KDZ as a proper reset. Hope it works buddy!!

Just to make sure you know. TWRP is your recovery. Your last message said you did not have TWRP?
When I first rooted my phone (and subsequently when I install a .kdz), I have to go into the bootloader and install TWRP. I personally do this by using the above command "fastboot boot recovery.img" with the recovery.img being placed on my computer in the same location as my adb installation. This command only boots up TWRP but does not flash it. I then flash twrp by having a copy of it on my external sd card. Within twrp you can select to flash zip, or there is an option to flash an image. I use this to flash twrp (from twrp... its a little inception like but it works). Once you have twrp up and running, you can install a rom. If you want to do flash a .kdz, I have found you need to be on a stock based rom in the first place hence why i referenced the v20a full system zip.
Hope that made sense.
Regards,
Ravi

It is late here and with me being tired I said recovery instead of download. I can boot into download mode but when I try to boot into recovery then it just goes straight to the LG splash screen and it will either remain in that screen or the green Demigod screen would come up.
I'm off to sleep and away from my laptop as I have to be up in 5 hours. Luckily I still have my Note 4 so at least I'm not without a phone in the morning. I will try the steps what you have suggested just as soon as I get back from work.
Many thanks

I have finally got chance to sit down and have a go at performing the procedure listed above. I downloaded the adb and fastboot installation as outline here. It is the minimum to what this thread says I will need for my device. I moved the recovery.img to the installation location which were in Windows/programs files (x86)/Minimal adb and fastboot. I launched the program and typed in 'fastboot boot recovery.img'. I tried this in download mode, charging mode (phone off) and while on the LG flash screen where TWRP didnt load but in all cases I have had no response at all.
If someone can help the much appreciated.
