[Q] "Android" Logo Bootloop

Yesterday I wanted to flash the new CWM (5.8.4.0) but I accidentally flash using fastboot boot boot.img
Then it kept rebooting into recovery
After panicking a few times, I used Hasoon2000's allinonekit to flash stock recovery, stock kernel, relocked and reunlocked bootloader, factory reset through hboot.
Now im in a bootloop but instead of the usual htc with beats that i usually get, a simple logo featuring the word "android" is all that showed up on my screen. Sometime when I restart it would show a harddisk or something like that with a green refresh logo. In cwm my phone can't detect my sd so I can't flash my nandroid backup.
Can someone help this noob

Boot into fastboot.
First turn on the phone.
Hold both Power and Volume Down until the screen turns black, after two seconds release the power button only, it should boot you into fastboot, you can also try just holding both buttons, not sure about that so if it won't boot into fastboot try both ways!
When it boots into fastboot, open up command prompt and execute the command fastboot erase cache, this should make you able to boot into recovery again.
Good luck!

I can access recovery now. The problem now is the android bootloops

Do you have any ROMS on your SDCard?
If you do, follow these steps please!
First of all, find the boot.img of the ROM you have on your SDCard, do this by downloading the ROM to your computer again and extracting the boot.img or using franco's or whatever other one there is.
Put the boot.img into the directory where your fastboot.exe is located, boot back into Fastboot and execute the following commands, fastboot flash boot boot.img and then fastboot erase cache.
Boot into recovery from fastboot, Wipe Data -> Wipe Cache, browse for the ROM and flash it, this should fix your phone!

I was running ARHD 6.1.1 before. but like I said in CWM it cant detect my sd,
it says there is no such file. any ideas?

Put phone into Fastboot and run following commands.
fastboot flash recovery r1--recovery-clockwork-touch-endeavoru.img
fastboot erase cache
Boot into recovery see if it recognizes the SD.

flashed that recovery, cleared the cache
when I went into recovery i chose zip from sdcard but then no files found
in Hboot it said SD checking...
failed to open usb master mode
failed to open usb master mode
only then would it show the options:
fastboot
recovery
factory reset
simlock
showbarcode
image crc

what is your recovery version? 5.8.4.0?
If you flash the latest recovery 5.8.4.0, then you should be able to view your SD Card and also infact,
if you go to ADVANCED Mode in the latest Recovery, connect the USB, it will detect your PC. Transfer the required files.
You have recovery now, try mounting the SD Card. Make sure you have enough charge ( >50%)
Please do not panic!

I will try that. Although i don't know how much battery I have left cause it suddenly turns on and bootloops after I charge for a particular amount of time

did you fix your phone now? if you fix pls mail [email protected] me cos we have same problem im using HOX stock " android logo "
even i put file on cwm 5.8.4.0 SD failed open master mode

[Q] Maybe in a bootloop?

Rooted my phone using Temporary CWM method, installed Titanium Backup and restored from my old phone. Selected All Apps and Data. Rebooted my phone and I assume that it is now stuck in a bootloop. It gets to the ASUS and Intel Inside screens, then I get a spinning circle forever (well, at least 3 minutes).
Where do I go from here? Reflash the ROM and start over and don't restore system data? Is there an easier/quicker way?
Thanks

Go to fastboot mode by holding the power and volume up button,connect USB cable be sure that you installedmusb and fastboot driver.go to folder of fastboot and hold shift key then right click open command window here and type:fastboot erase cache then enter fastboot reboot and voila..

Thanks for the reply, but that didn't do it.
I was able to execute the commands, but still no luck. I got into recovery to try and wipe from there, but got the dead android. I them held power up and tapped vol up to get into recovery. tried to wipe cache from there and the phone just sat there for 3-4 minutes with nothing. Now when I get into recovery, I get a flashing dead android, and the power/vol up trick doesn't work. I can still boot into fastboot.
Di I just need to reflash the stock image? Or is there something else I can do?

I had the same problem as yours and it took 3 hours before i figured it out and managed to run the phone normally.I downloaded all the files,drivers and latest prerooted system img. here in this forum.you can download it there and there is the instruction how to do it.
To Begin :
1. on Fastbootmode connect your device and on the flashtool folder hold shift key and right click and go to open command here,be sure that downloaded images are in the same folder.Recovery img.,Boot Img. and the big pre-rooted System img.
2. type fastboot devices then hit enter key - the device nos. should appear and you can start now to flash...
a. fastboot -w then hit enter this will erase the system
b.fastboot flash system system.img then hit enter key
c.fastboot erase userdata then hit enter key
d. fastboot erase cache then hit enter key
e. fastboot reboot then hit enter key..

THANK YOU!!!
Thank You, Thank You, 1000 times, Thank You.
I did everything you mentioned, with a few small exceptions
1. Make sure you have the lastest version of Fastboot
2. Instead of step b above, I did the following. Not sure if it was needed or not, but it worked for me
fastboot flash fastboot droidboot.img
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
3. At the end, after I did a Fastboot Reboot, I got the dreaded dead android again. I nearly cried. However, I rebooted again, and everything seemed to work. Note that on the first boot, it may take 2-3 minutes for the OS to come up.
4. All of the files and great insight can be found here: http://forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596

Urgent please!!! unable to enter fastboot after wipe partition cache and bot error..

Its been a month my phone sitting quite...
After updating to latest version i decided to wipe partition cache while on the process it showed erasing android bot then restarted and hung on asus logo for nearly an hour so i decided there is some problem and force switched off then after switching on it shows the blinking android error bot.........im unable to enter neither recovery mode nor fastboot mode(when entering it shows for a some seconds waiting fastboot cmd bt then comes again to the normal boot screen)....
Its been nearly a week i went thru various post and tried most of the methods like entering recovery mode thru adb(as im unable to enter fastboot mode it shows in cmd waiting for device) and pressing both buttons same for stock recovery(it shows some lines saying in last line can't mount recovery)
SO CAN SOMEBODY THROW LIGHT ON WHAT EXACTLY NEEDS TO BE DONE TO RECOVER MY PHONE FROM THIS ERROR.... would be grateful and thanks in advance.

LG G3 Bricked / No ADB / No download mode / No recovery

Hi,
Since the rom ( http://forum.xda-developers.com/lg-g3/development/rom-resurrection-remix-lp-v5-5-5-t3198675 ) of my phone crashed. After reboot, the phone is blocked on LG logo. Now, i can't enter in recovery mode (or in the download mode) and when I start my phone, it's fixed on the LG for 5 to 10 minutes, and after that it goes to a terminal (started fastboot mode).
I have read several tutorials to use fastboot to flash the recovery to reinstall a rom, but i have a error when i tried to erase or flash the recovery partition.
I look on my phone, and this error appear : "failed to send erase grp start address".
what can i do to fix this error ?
Thanks.

up please

Use the "boot" command instead of "flash" and it should boot up into recovery or downloadmode, depending on which file you use

I tried but i am stucked on teamwin logo.
Which file do i use for download mode ?

Hard to tell, there are some laf.img files floating around on xda and google or even better, extract the laf.img from the stock kdz depending on your android version (for instance you flashed 6.0 you pick the 30b kdz and extract it with the firmware extraction tool)
I would suggest you to and try to use the boot command with them..
Be carefull, do not use the flash command until you found one that boots into downloadmode properly or you can loose your fastboot mode aswell
From then on you should be able to boot into the downloadmode and flash a new firmware via the lg flashtool

I need help please. What can i do to re install a rom ?

Does your PC recognise the port.?
I found tutorial under bender_007 signature. People seemed happy with tool.

Doesn't hurt to read and ask some questions.

Can you elaborate, how exactly your phone crashed, it is very unlikely that it will mess all the partitions just by crashing the rom?

The rom crushed twice, and now i can not access to recovery to install a new rom. I only have access to the fastboot command. Adb not working.
I tried to boot on recovery.img, but it's not working.
Thank for your help.
Regards,

Help please ?

Today i can connected to my phone with ADB when i tape this fastboot command : fastboot boot ./recovery.img.
I can too go into my phone as root with adb command : adb shell.
i tried to push flash_image on my phone and use it, but it donesn't work.
how can i flash my phone with adb command ?

Boot-Looped device. I'm willing to try anything at this point.

So before I get linked to a bunch of solutions, here's what I've tried so far as I do have fastboot access:
I've tried flashing the latest factory image from Google. Both manually from fastboot and with NRT, all to no avail. It shows the Google logo then reboots repeatedly. I've tried entering recovery to factory reset there after flashing, but the device won't get into recovery.
I've also tried this method, but I can't get the device to enter download mode. It shows that it's entering it for a moment when I plug it into my computer while holding volume up, but then reboots into the bootloop again.
There's one weird thing that should be noted that makes me think this is some weird software issue, and not a hardware failure. I let the device bootloop all night last night until the battery died. When I powered it on this morning it went all the way to the Android setup page where you select wifi, etc and go from there. However, when I plugged it in and kept going through setup, it rebooted and has been looping since. I've contacted Google and they're supposed to conference call me with LG to see what we can do. Do I have any options other than that? Thanks for any help.

From bootloader
fastboot erase cache
fastboot format cache
fastboot erase user
fastboot format user
BTW what exactly is happening when you say it doesn't enter recovery?

I choose reboot recovery from the fastboot menu and it just boot loops. It won't enter recovery.

what if you try
fastboot boot twrp.img

I've bootlooped so many times I don't know where to start.
So you flashed the factory IMG from your bootloader correct.
Fastboot -w will wipe without wiping system.
Then reflash your whole system. I would redownload from the Google site through Skipsoft...the easiest way. When it asks to keep or flash new recovery you want to flash the stock recovery.
http://forum.xda-developers.com/nex...olkit-skipsoft-android-toolkit-nexus-t3230444
You'll have to reroot afterwards which you can also do through skipsoft.
Profit... Thank me if I helped.

It's a Hardware issue. Installing system again will not fix it. Send it to LG for a repair. My phone had the same issue.
