Well hello guys. I tried to flash cwm5 using the stock recovery on my gio running 2.2.1 and it seems to have failed the flash and whenever i try to enter recovery its just stuck on the initial samsung logo. For a few times i could have booted normally but after trying to enter recovery via rom manager im stuck on the samsung logo permanently. The only thing i can do is enter download mode but im running win8.1 and it seems this particular phone drivers dont like win8.1 so it errors out with device enumeration failed. I tried everything removing battery for up to 20 minutes, leaving it on for a while, reconnecting download mode repeatedly. Can anyone share some insight on this.
Edit: i managed to flash via odin on xp, fixed it.
Funny, I had the same exact problem and I tried to find a solution for a week. I accidentally flashed CWM6 for ace to my Gio and it got stuck to the Samsung logo. I got the error too on Windows 8.1. The problem is, well, Windows 8.1. It has something to do with how Windows 8.1 handles device validation. I would sen a link, but I don't have enough posts to do that. What I did was, I installed Windows 7 to a VHD-image with VirtualBox, copied the image to C:\ root and added it to the boot menu with EasyBCD. (Boot menu editor) I tried to connect the USB and it worked! So, try to flash a new recovery with a computer running Windows Vista/7/8, not 8.1.
Wondering if any of you guys can advise me - having strange problems with fastboot (windows 8.1 and Zenfone 2 ze550ml). Wanted to flash the pre-rooted image to my device so downloaded it and extracted to the flashtools folder and renamed system.img then hooked up my phone. Checked adb drivers were installed and adb devices command returns a code string, so assumed all was good to go with flashing. However, on entering any fastboot command it just sits at "waiting for device". Tried manually starting the phone in fastboot and then connecting it, and this did enable me to execute fastboot commands (reboot or reboot-bootloader work). However, fastboot flash system system.img just results in a message about file size and then "failed to load system.img"

You need to rename the system image to system.img and put it where the fastboot file is. It's looking for it but can't find it.
No, don't think that is my problem - as I said I extracted it to the flashtools folder, so it is already where the fastboot file is. And anyway, though I'd like to solve the problem of flashing the system.img, I am kind of more interested in why I can't get past "waiting for device" without first manually entering the fastboot mode.
Cause Windows sucks. I'm on Linux and no issues. Maybe someone on Windows can chip in?
I can easily do a quick ubuntu install and try it that way if you think it might work better. At the weekend maybe. Could you give me some pointers on how to do it in linux if I do? Would be much appreciated!

I have encountered that problem with the "waiting for device" while I was flashing pre root rom.
Try the cmd adb devices
Then it will list the device connected to the computer...if it says not authorized, then you need to check the phone which is turned on and a pop up window with the RSA key and tap on trust this computer or something..
Then repeat adb devices and it should say allow or something..then it will allow you to flash.
(double check the commands online, I might missed something)
Nah, don't blame Windows... I flashed mine with Windows 10 and worked wonders.
Also... could it be that PC isn't USB 3.0? Perhaps system.img transfer is stopped somewhere during the copying phase?
Thanks, but actually the first time I tried it I did the adb devices command and authorised my pc on the phone. When I connect and do adb devices now it shows the string of numbers code for the device. However, still can't get past "waiting for device"
My pc has both usb 3 and usb 2 ports. Tried on all of them and with various different cables including the asus issued ones, all to no avail.
Can u post a pic of your flashtool folder?
Sent from my Nexus 7
Here is a snap of my platform-tools folder and cmd window
Did you manage to find a solution to this?
I updated the zenfone 2 via OTA to the latest system update.
Ive read and downloaded all relevant files to install the pre root img from the correct sources.
Now when I hold power + vol up. I can see the droid on its back. I choose the RECOVERY option and press power button to select.
When phone reboots it goes to droid icon and says installing system upgrade.................then error appears! No recovery mode!
All the correct drivers are installed into Windows 7, the phone asks me to allow RSA key connection to laptop.
Ive tried the flash tool installer 1.0.7 with phone connected and system img (renamed) and still nothing.
Anyone got any ideas?
Ive factory reset twice in a row and allowed debugging.
Ive placed the (renamed) system.img into the fastboot folder and tried the open command with line ' fastboot flash system system.img' and the reply is usually unable to read system.img or device waiting.
Ive installed the latest android sdk develppment kit and still unable to root using this pre root image.
Im familiar with android and how to follow instructions on rooting, but this zenfone 2 is mind boggling.
Thanks for reading. I know its someone else post. I didnt want to start a fresh post with the same dilemma.
Any advice on whats going wrong would be appreciated.

Hit power and vol up again, just really quickly. Don't hold it, just press and let go. Sometimes it takes several attempts.
hkdmjack, yes your right managed to do it at last.

Hi guys, I am facing quite a difficult problem at the moment.
My friend has "accidentally" attempted to use an Asus Zenfone 5 rooting method to root his zenfone 2 550ML.
When I received it to take a look at it, I instantly noticed that I could not get into fast boot (or droidboot). I expected to see usual droid with text on the left side and also expected to be able to select from a number of options using the volume keys (i have some past experience), but instead am met with this solid usb logo. One like this: h ttp://zenfo ne-blog-forum.2 8820.n7.nabble.c om/file/n4 5/P_20140728_051139 .jpg (remove spaces)
I did some research, and found that there were many "bricked" zenfone 5's which were stuck on this usb logo, however this zenfone 2 can start up normally and be used throughout the day normally. Only when I try to enter fast boot, by either ADB commands or by power + volume up, I cannot get past the usb logo.
I have linked up the ZenFone to my computer, and confirmed that ADB devices correctly lists the device (I have usb debugging enabled), however, when I try to go to fast boot and am met with the usb logo, my computer does register and detect the phone, however, under device manager it has a yellow triangle with the device named "" MOOREFIELD". When the ZenFone 2 is in this usb logo state, I cannot access any fast boot commands. I am quite stumped at the moment.
Any help please? By the way, I use a windows 8.1 computer with usb 3 ports. However, I have tested using different cables, and on a windows 7 laptop with usb 2 ports, still to no avail. Should I try and update the firmware using Asus' software? Or is there a better solution?
Thanks
Edit: My friend claims that he did not see at any point in time, the flashing on the zenfone 2 start. He was faced with a "<waiting for devices>" or something similar message, telling me that the phone was not fully in fast boot yet. If I can get it into fast boot, I am sure I can reflash the custom stock onto the phone, and most issues will be resolved.
same error
i have the same error by my zenfone2 after update
please help

my orginal firmware is CN and i wanted to change to WW mode i tried by pc .... now when i conect phone t pc it want moorefeild driver for conection and i dont have those ,,
Whenever I try to flash system.img it gets stuck on "writing 'system'..." and just hangs there. I have left it for over half an hour and it still didn't work. Does anyone know a solution to this problem?
Hey guys,
So after a while without any responses, I headed over to Asus customer service to receive a very unhelpful reply.
I gave up hope of finding an answer online and so I decided to take a leap of faith by updating the firmware via the Asus Update app on the phone.
I upgraded from 2.14 to 2.15 and miraculously fastboot seemed to have restored itself. I am not sure whether or not every single update restores fastboot, or whether the update to 2.15 does, but I'm glad that it has been fixed.
My previous problems of being unable to detect fast boot devices has been resolved. Hopefully others who have experienced the same issue can find this post helpful.
Hi All,
Just got the G3 and trying to root.
I've tried scripts and gui/1click roots and none will put the phone into download mode!
I've the LG drivers installed and adb running.
All the methods fail at the same point. They push the files to the phone, ok. They try to reboot into download mode and the phone just restarts!
I've tried the manual way (usb plugged in while holding vol+) the phone boots normally!
I've done nothing else to the phone that would wipe anything. All I've run are a number of ways to root.
Its a a D855 (v20i-EUR-xx) on 5.0 running stock everything. I've tried 7 (yes, 7) different usb leads and 3 pc's (windows 7 and 8).
Can anyone suggest something? Or a test to see if there's a problem with download mode s/w ??
Many, many thanks....
Did you try from through adb "adb reboot download" command?
Hi all, so this is my first post and a last resort attempt at recovering my phone, after hours of googling and downloading everything suggested by various forums, and still being stuck... Sorry for the long post, just trying to list all my attempts to fix it.
So, I've been on stock 5.0 Lollipop (v20n) for a long time, with the only issue being that android OS suddenly will decide for no good reason to make my phone super hot and drain my whole battery in 2 hours flat... Nothing that worked for other people worked for me, so yesterday I decided f*ck it, i'm gonna root and flash Fulmics 5.0, using this: http://forum.xda-developers.com/lg-g3/general/guide-root-method-lg-devices-t3129197 (tried the classic method).
Everything went as per instructions, until I went "Send_Command.exe \\.\COM12 < reboot" and the phone got stuck in a bootloop...
So in other words, my phone is not rooted yet (thus nandroid/titanium backup was not made), TWRP was not installed (so i cant reflash stock kitkat). Latest LG drivers are installed (v4.1.1.0 from http://lgusbdriver.com/windows/lg-usb-driver-v4-1-1-0). Adb and fastboot are installed (http://forum.xda-developers.com/showthread.php?p=48915118#post48915118).
I can boot into download mode (Volume up + plugging in my usb cable), but i cant get adb or fastboot to see my device, when i try to flash twrp.img though command prompt! Downloaded the LG Flash tool 2014 to try and reflash stock kitkat 4.4.2 v10E, but it also can't see my device!! LG PC Suite can't see my phone when trying to connect...
I have removed the LG drivers from device manager and reinstalled the 4.1.1.0 drivers several times, but everytime i plug in my cable Windows (7 ultimate) tries (and fails) to install some drivers for it, even though i installed them already.
I tried to do a factory reset (holding volume - and power button, releasing and pressing them again when i see the LG logo), it gives me the option of doing a reset, but it goes back to the bootloop.
I have installed the Android SDK files (https://developer.android.com/studio/index.html), not the whole 1187mb SDK bundle, just the 144mb installer_r24.4.1-windows.exe. But i cant get my pc to see my device!
Went to a friends house and installed the LG drivers on his pc, installed adb and fastboot (as above), opened a command prompt in the folder where the adb and fastboot dll's are, and neither "adb devices" nor "fastboot devices" lists my phone.
What am i doing wrong???
TL;DR LG G3 d855 stuck in bootloop, but can boot into download mode, no root, twrp recovery not installed, LG drivers and adb fastboot installed on pc, adb refuses to see my device but windows tries (and fails) to install some drivers when i plug the cable in. Factory reset didn't work. Need help please!
Hi all,
This is my first thread on this website and I am not that expert of rooting and installing custom ROM's. I am trying to find a solution on your website for 2 days but I couldn't solved although I tried everything.
I have an issue with my LG G Pad 8.3 (LG V500) tablet. It was installed 5.0.2 stock ROM (Korean version) and I decided to root the device and install custom ROM. I used King Root to unlock the device. Then I installed TWRP thing to my tablet and started flashing ROM process. While working the tablet restarted automatically and it was stuck at the startup with a LG icon on the screen.
I decided to make factory hard reset it in order to get rid of this but when I try to make factory reset with button combinations I get the following error;
* Confirmed *
Secure booting Error!
Cause : boot certification verify
Then I searched for the forums and first installed Android Studio, then by using SDK manager tools, I also installed USB drivers.
As the device can connect download mode, I installed adb thing and tried to fix it. But apparently laptop does not recognize the device. I run the command "adb devices" and there is no devices in the list.
I also tried to use twrp recovery tools but again it didn't recognize the device.
When I check the Device Manager when the tablet is connected to laptop on download mode, I can see LGE AndroidNet USB Serial Port (COM4) thing installed. I also tried to install Android Device drivers (Android ADB Interface, Android Bootloader Interface, Android Composite ADB Interface) but they are not working properly and they have question mark on their left side.
So as you can understand I am drawning with the issues and don't know what to do next. Apparently laptop does not recognize the device but although I checked the xda forums and other forums for 2 days, I couldn't solve. I would really appreciate if you can help me.
