Hi there.
I updated my phone the other day and it ended up doing reboots with an error message regarding the update process. Before I hand it in for service, I wanted to make a copy of all the contents of the device..
So far, it looks like using some recovery kernel image and ramdisk is the right way to go, using "fastboot boot". What's a good image to use?
It's important that nothing is changed on the phone so I for example void the warranty.
Thanks,
Morten

My device is C6903 (14.4.a.0.108) bought from the Philippines. It's already rooted and has an unlocked bootloader.
The problem is when I installed this kernel http://forum.xda-developers.com/showthread.php?t=2699803 it now wouldn't boot it just shows the Sony logo and after 2 minutes or so it just blacked out. but when i tap the screen on a dark room the screen shows the black background without the sony logo and after a moment it darkened again like its in lock screen (Its really hard to describe).
I flashed it using fastboot. with this command
/ fastboot flash boot boot.img / and after I input this command
/ fastboot reboot /.
Its still charging and it shows the battery icon when charging on an off state. It can still be recognized by fastboot when i connected it to the computer.
Ive already hard reset it using the button on the sim card slot and the other method the power button and the volume up. It didn't really helped. help me guys Im new in this flashing methods. What should I do?
Hi,
Did you read the requirements at the beginning of post number 1? Did you meet those requirements? The best place to ask about this is in the kernel thread you linked in your post. If that doesn't help you, you can ask for help here....

thanks for replying. I have managed to get out of the situation but now I'm facing another one. My phone is now on boot loop. I tried using flashtool but it wouldn't work. While on flashboot doing its job, my phone would just boot up and go again on a boot loop. flashtool log would just say device disconnected.
I think I found a way to do another trick using fastboot but I don't have a custom recovery installed. Is there any way that I can install CWM or any tools like it using only fastboot? I've been looking for it the whole time but I can't find one. I'm new to this thing by the way. Thanks again!
I've found one. http://wiki.cyanogenmod.org/w/Template:Recovery_install_fastboot
Can i flash this Z1-lockeddualrecovery2.7.154-BETA.flashable.zip (if its possible ) instead of the .img that was mentioned on the site. I can't find a recovery.img for my device.
Again, please ask in your device section linked above.
Thanks!
Thank you. Thread closed.

I decided to root my phone today. Found an article on wiki.cyanogen
got the boot loader unlocked, loaded the bot.img file onto the phone and had it rebooted, ever since it hasnt started. Just a black screen for a very long time.
Hi, thank you for using XDA Assist. I would try returning your device to stock. If you don't know how to do that see your device's forum here, http://forum.xda-developers.com/xperia-z2. They are the experts on your device and will be able to help you.
Hey, guys good afternoon. I have a Cubot Note S which I manage quite stupidly, to brick. The phone was rooted with KingRoot and I accidentally press to update to the latest software version from the Update Center of the phone and before it managed to complete, it showed an "ERROR" message. After that, I stuck into a boot loop. I've been searching the internet for a stock firmware of the phone in a .zip file because the Cubot has something like a stock Recovery mode, which I can boot to, to factory reset my phone, to boot into bootloader or apply an update through an sdcard etc. So far I only found a rom on needrom and it is in .rar and has many other irrelevant files in it. It has instructions below how to perform a clean flash of the ROM, but something goes wrong at the process. Either the SP-DMT (Flash Tool) doesn't work properly or my computer doesn't recognize my phone and I can't find the proper drivers for it. Has anyone ever been in this situation before with a chinese phone? Please help out with this because the cell phone belongs to a dear friend of mine and I can't afford to buy a new one these days. Thank you in advance.

Hello guys,
Im new at this forum.I visited here lots of times to get some information about Kernels,ROMs.unlocking process..vs Sorry if this thread is already opened but I have nothing to do.I visited every forum,every material that I found but I have nothing now.
First of all, I just bought my z00vd 2 weeks ago with speaker problem. I sent it warranty because of it but they sent me without fixing.I just wanted to root the phone to fix the problem.After I root my phone nothing happened.Then I just wanted to unroot it to sent it warranty again. I did something wrong.
I just type the cmd "fastboot oem lock" then I reboot the phone. It is in bootloop now. I cannot reach to the recovery mode also. When I click recovery mode its freeze with Asus logo.. I tried some other things like "fastboot erase cache" also not working in fastboot mode.It gives me an error LIKE " FAILED <remote:unkonwn command>
Do you guys have any idea about this problem? I just want to recover my phone stock mode and send to warranty again.
Thank you so much...
Im still looking for an answer my friends. Does anyone have any idea?
