xperia C6802 doesn't go beyond DoomKernel logo - Sony Xperia Z Ultra

Team,
I was on Android Lolipop 5.1.1 stock os. I was searching on how to root C6802 and everyone thread said, we must downgrade to Android 4.4.4 (build .108). Unfortunately, i didn't get it. The problem I now have is, I installed the Kernel ZU-DooMKernel-v22 through Sony Mobile Flasher (flash kernel) without even rooting the phone or installing a new custom ROM and now when i turn on the phone, it shows the DoomKernel logo and it won't go beyond that. Earlier it showed twrp but now it isn't going to it.
I had unlocked the bootloader per the instructions by Sony by getting the unlock code.
Can someone tell me how to fix this issue ? I am lost
Thanks
Arun

you're better than me. i was on 4.4.4, flashed the same kernel, now my screen won't even turn on.
using flashtool, sony emma & pc companion, can't find a solution. downloading stock using xperifirm keeps disconnecting & getting speed of 9-30kbps

You can try reflash the 5.1.1 firmware with flashtool but only flash the Kernel section by check all the box inside firmware detail except the Kernel.. Leave this box uncheck. And connect the XZU to your pc in flash mode( turn off the phone,on off condition press and hold volume down button while you connect the phone to the pc...and you in flash mode)...hope this can fix your problem.

If you want to root XZU run lollipop. Don't flash doom kernel into your system,it will end in bootloop. Just try to hot boot the doom kernel by flashtool in fastboot mode.this way will temporary instal doom kernel in your system,so you can enter to recovery mode and instal superSU.zip via recovery mode.after that you can reboot to original kernel to prevent bootloop. And you get rooted.you can found the doom kernel V22 and superSU in z ultra development thread...sorry for my languages..

i've flashed back stock 14.4.a.0.108 firmware using flashtool. my limitation is having a cracked touch screen (replacement cost an arm & a leg), now i've lost root & dare not do anything further.
it gave me sleepless nights trying to revive it. phones with locked bootloaders are a pain in the a**. previous similar phone was a htc sensation xl, had half of my hairs gone grey rooting it. i've sworn not to own any such phones in future. disposing off the xzu now although i love the large screen & processing power.
my other galaxy s3 is just so easy & almost unbrickable
thank you for your reply

[FAQ] General FAQ for Xperia Ray [FAQ]

General Xperia Ray FAQ
How do I root my phone with a locked bootloader?
It depends on which firmware version you run, but most of the Sony firmwares only requires you to run a software that will root the phone.
The only firmware for Xperia Ray that is unrootable now is the .64 firmware, the only to root a phone that runs that firmware is to downgrade to the .42 firmware using flashtool.
If you want to root the .42 firmware, just download "Flashtool" and enable usbdebugging. Then just press on the unlocked lock.
http://androxyde.github.com/Flashtool/
If you want to root the .562 just download the rooting toolkit by canerpense, and then just enable usbdebbuging and follow the onscreen instructions.
http://forum.xda-developers.com/showthread.php?t=1600728
If you want to root the .431 its kinda complicated and its not recommended for noobs that dont know anything about flashing firmware. You can find the tutorial here: http://forum.xda-developers.com/showthread.php?t=1682224
How do I root my phone with a unlocked bootloader the easiest way?
You can either use the same metods as above, but you can also flash one of these kernels:

How do I unlock the bootloader without loosing my warranty or drm data?
To unlock the bootloader without loosing the warranty or the drm data, you should unlock the bootloader using the testpoint method. You can find how you unlock the bootloader using the testpoint here:
http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working
How do I unlock the booloader the regular way?
If you just want to unlock the bootloader the regular way, you can visit Sony Mobiles site and they should have a tutorial that guides you through the whole process. Here is the link to Sonys bootloader unlocking site:
http://unlockbootloader.sonymobile.com/
How do I flash a custom kernel the easiest way?
The easiest way to install a custom kernel is to flash it through Flashtool, but it requires a unlocked bootloader:
1. Download and install flashtool from this website: http://androxyde.github.com/Flashtool/
!!!Dont forget to install the drivers for Xperia Ray!!!
2. Then plug in your usbcable and hold volume up at the same time to go into fastboot mode.
3. Launch flashtool and click on the flashbutton, then click on fastboot mode. Then locate the custom kernel you downloaded and open it with flashtool.
4. Now flashtool flashes the kernel, but dont unplug the cable before its finished, that will only lead to a brick.
How do I flash a custom rom on a Xperia Ray with unlocked bootloader?
1. Flash a compatible kernel using the method above, then copy the roms update.zip file to you sdcard.
2. Turn off you phone and press the power button, after pressing the power button you should mash the volume down button to access CWM.
3. Now you should go to "Install zip from sdcard", then you should on the option named "Choose zip from sdcard", then you should browse for the rom that you have pu on your sdcard and let CWM flash it.
4. After flashing the rom you should "Factory reset" your device from CWM and Wipe Dalvik cache. Now its time to reboot, the first boot will take a while but thats because its setting up files for using the device.
Unbricking FAQ
How do I unbrick my bricked phone with a locked bootloader?
If you want to unbrick your phone just open Pccompanion and go to Support Zone and press the update button.
Then a popup should appear that says that it cant find your phone, and under that there should be a button named repair. Press the repair button, and just follow the instructions.
You can also download a stock firmware ftf and flash it through flashtool.
How do I unbrick a phone with a unlocked bootloader?
Just flash another kernel through Flashtool and install a a new rom.
You can also flash a stockrom using one of the stock ftfs.
Is there anyway to unbrick a hardbricked phone?
No and yes, but you cant unbrick it at home.
I recommend you to send your phone to Sony so they can repair it for you, because you can mess up things really bad when you are trying to repair it at home.
Accesories
Does iPhone headphones work with Xperia Ray or does it need a adapter?
No, they wont work without a special kind of adapter.
Is it recommended to use a screenprotector?
Yes, its recommended, the Xperia Ray screen gets scratches very easy. If you want a good screenprotector you could choose either "Copter" or "Invisible Shield".
And more reserved stuff
Wonderful tut for newbies... I think it should be sticky.
A small doubt - Factory reset before flashing ROM or after flashing ROM? I usually do before flashing and it worked till now!
[Q] Xperia Ray Blank Screen
Recently, my friend's Xperia Ray doesn't shows any splash screen (SONY) after downgrading ICS 4.0.3 to GB .42 with locked bootloader... then we returned back to ICS 4.0.3 again... but the problem still exists... so we unlocked the bootloader via SE official tech and flash back to GB... still doesn't work... we tried installing custom kernel but can't enter recovery...
Now, it's on GB .42 rooted but no splash screen, no boot animation and deep sleep...
Any solutions, ideas???
Can't try PCC due to overloaded server... SEUS has only outdated ICS but still not working...

[Q] Have I bricked my C6806?

Hi everyone,
I just bought a brand new Z Ultra C6806. I plugged it into my computer, installed the My Companion software, and then proceeded to root the device via the Chinese root, which seemed to work just fine. I then tried to unlock the bootloader with Flash Tool, but couldn't get Flash Tool to recognize my device. It kept on saying that I needed to install drivers. I'm doing this on a windows computer, and I already navigated to the drivers folder and installed the z ultra drivers.
I then got fed up with that and saw the thread that let you flash a recovery with a locked bootloader. So I followed those instructions and had a working CWM and TWRP. Except then I wiped data and system and flashed the CarbonRom custom rom, and now my phone won't boot at all.
I'm hopeful that everything is not lost since when I hold volume up and plug my phone into my computer I see a blue LED, which I have gathered means that it is successfully still entering fastboot mode?
How do I get Flash Tool to recognize my device? And is it possible to unlock the C6806 bootloader or have I been deeply mistaken all along?
Thanks for any help

You just need to use 'flashtool' and flash a FTF file.
But like you said before you'll need to ensure drivers are installed properly. flashtool will need to say:
'device connected in fastboot mode' or
'device detected in flash mode'
Download the latest version of flashtool. Then when you select the type of device, you can select Xperia Z Ultra.
and make sure that ADB is installed (windows will detect new device has been plugged in, and if it wont install drivers, you will need to tell it where to find them)

Reinstalled flashtool drivers for z ultra and flashmode and fastboot, pointed my windows drivers interface to the driver file I downloaded from the sony unlock bootloader website and still didn't get anything on my laptop.
Did the exact same things on my desktop and everything is working fine now, flashtool recognized my device, flashed a Sony FTF, unlocked bootloader successfully, playing with CM now.
Still not sure why this is the case, but alls well that ends well I suppose, thanks.
install flashtools driver you can find it in Flashtools folder. PC need driver when xzu in fastboot mode.If you use USB 3.0 like me try different usb slot.

Hi Guys,
My first Sony Phone (previous Samsung User). I have the US Version C6806 LTE model. I have a similar question. I have unlocked my bootloader successfully via Sony's website. I want to be able to install TWRP and backup original ROM before applying custom ROMs. Doesn't look like there is a root available for this phone model yet? I am on firmware 14.1.B.2.257. My questions are:
1 - Is there a TWRP image I can flash on my model via fastboot without having root? Then boot into TWRP and backup the ROM?
2 - If not can I flash any of the images that I seen on XDA via fastboot that include the Root and TWRP in them? Or will those not work with .257 firmware?
3- If none of the options above work can I download an FTF image (older version) that I can root and use TWRP and if so which image do you recommend that would work with my phone model and LTE network on AT&T?
Thanks for all your help and sorry for all the questions I am a noob with Sony Phones. I did research here and seems most of the threads and images are NOT for C6806 which I have.
I think all tyour questions are answered in various threads in the X-ZU forum...
You have gone about it all ass about face, you should have downgraded to .532 then rooted with kingo (looks like is is safe?). Once rooted you should of then backed up your TA partition in case you ever need the phone serviced.
I dont know if TWRP is working well in any of the boot.img but CMR works fine (except for the date of the backups)
any of the firmware/ftf/ROMs will work with any of the Ultras as far as I know

I flashed a .532 firmware still no safe root method from what I can tell. Looks like I need to flash an earlier version or a FTF hopefully that contains root and custom recovery. I will keep reading and researching. Thanks for the help.
do you want to end up on a rooted stock firmware?
as you have already unlocked the boot loader you can just flash one of the kernel/boot img with recovery and then flash whatever rom you want from there...
I also run into Cyanogen Recovery and have trouble going back to FlashTool with my chromebook. I am a bit panicky, but your post is comforting and ensuring.
I got the C6806 xperia z ultra in year 2014. I have been using it as a home primary PC.

Sorry for posting in the wrong thread, so here once again:
I rooted my Z2 on 4.4.4 by installing DooMKernel v07 and flashing SuperSU via recovery.
Then I flashed original kernel from ftf and relocked bootloader by restoring TA.
Everything seemed to be OK, but I can't Mount System R/W and because of this I can't install dualrecovery.
Any Ideas what went wrong?

The 4.4.4 update contains lock on the system.. You need to disable it... Try searching for disable ric as a zip file..
It is a safety feature...

I found remountrebootfix.zip. When I install that I loose Root.
Flashing SuperSU brings back root but /System is still R/O
Help please...
EDIT:
Finally got it working.
Don't know how but I can Mount /System R/W now...
EDIT2:
Relocked bootloader and it's gone again...
EDIT3:
Found out there is a file "enable" in /sys/kernel/security/sony_ric. As Long as this file is there Mount R/W works, but it gets deleted after lock BL.
I could copy it to SD, but there is no way to push it back to /sys/kernel/security/sony_ric after lock BL. Always get permission denied.
How can I manually get that file there (adb)?
Sorry I am a noob
Can u elaborate the method?
[ how to flash this kernel ] (via fastboot)
download the kernel image
save the boot.img to the folder containing fastboot binary
flash the boot.img using fastboot:
Code:
fastboot flash boot boot.img
reboot from fastboot
Code:
fastboot reboot
the device should now start booting
enjoy!
the only reason i want to use this method is that there is no custom recovery installed on my phone. And if there is any stock recovery, i cannot boot into it.
i own a Z2 (d6503)
-bootloader unlocked (everything is stock) i had rooted it previously but i think i lost the root access while updating the firmware to 4.4.4 using EMma
my problems
1. Google services are not working over wifi, but there is no problem with mobile data.
i have tried clear cache method already, factory reset, date/time thing. Sometimes few retries make playstore work.
2. Phone isn't turning on in recovery mode. neither manually (with buttons) nor with quickboot or PC
everywhere i found the same method: turn off, power on and wait for led to light up then press either of the volume buttons repeatedly. But the led doesnt light up
3. I have lost my DRM keys while unlocking the bootloader. (no TA backup). my bad.
what did i looose other than xreality engine? can it be recovered? how?
4. How can i root the new version of firmware android 4.4.4 (23.0.1.A0.167)
It Worked
this worked fine on my Z2 4.4.4

Z5C won't boot after kernel & recovery flash

Hi guys,
Just unlocked my bootloader and began the root process.
I followed part of this guide but without backing up my DRM keys. http://forum.xda-developers.com/z5-compact/general/summary-tutorial-root-sony-xperia-z5-t3360515
I flashed my kernel and the recovery O.K.
fastboot flash recovery recovery.img
flashboot flash boot boot.img
I've tried two versions of TWRP and two different versions of the kernel AndroPlus.
When performing fastboot reboot after flashing both files my phones LED blinks RED once and then does nothing.
Dramatic and scary. What can I do to fix this? When trying to boot without the cable in my phone just vibrates once and does nothing. Screen doesn't light up at all. I'm so worried.

It's tus stock kernel but with the habilita to support root
Similar issue for me
I've had almost exactly the same issue today:
- I unlocked boatloader using Sony standard process
- I followed the steps under 'How to Install CM13' within CTXz's guide here
- After flashing the Kernel and THEN the TWRP, I reboot and the phone flashes red LED, then green, then off, then red and then stays on green for a while (screen is blank). My computer registers that there is a new connection by making a sound but doesn't show up any devices that I can see.
- Periodically, I get the device disconnection sound and the green LED goes off, then red comes on, then solid green again until next cycle.
- If I disconnect the cable, the LED goes off. When I try to turn the phone on without cable attached, it buzzes but does nothing - no LEDs. I can't tell whether it is on or not, except that doing hard reset with PWR+Vol.Up gives no reaction.
- When I re-attach cable normally, the red/green LED sequence starts immediately with no need to turn PWR on, which would suggest that the phone is perhaps on.
- I am able to get into bootloader as normal and fastboot registers the device just fine.
- There is no yellow LED
I started with Kernel AndroPlus v24 and TWRP 3.0.0.0.
Failing that, I tried Kernel v20. Then I tried AndroPlus' twrp-2.8.7.0-E5823-32.0.A.6.152.
Have also tried Kernels v20 and v21 with TWRP 3.0.0.0.
I haven't had any fast boot errors - all flashes come back 'OKAY'.
I'd be very grateful for any help? Have I missed something?!
update to my post above:
I used: 'fastboot boot recovery.img' and this fired up the Sony logo with white screen and blue LED. However, after 10 mins of waiting, there was no change in status and I still couldn't get into TWRP with pressing Vol buttons, even after several restarts and unplugging, replugging etc.
Then, I realised the stock ROM on my phone before this whole process was Lollipop 5.1.1 Build 32.0.A.6.200. So, I flashed older versions of the Kernel and TWRP. Now, I can boot into the ROM and use the phone (almost) as normal except, being plugged in, it keeps re-detecting the USB cable. I now also get the Sony boot screen followed by yellow LED.
If I don't touch anything, it boots into the ROM. However, if I press a Vol button while the yellow LED is on during boot, then it just resets.
Thus, I still cannot get into the TWRP interface. Perhaps I need a TWRP version that is specific to my build - the one I have is from AndroPlus website and refers to the previous build (twrp-2.8.7.0-E5823-32.0.A.6.152.img)?
okay, further update (to save someone replying!)
I managed to boot into the system using AndroPlus Kernel v05a (I had Lollipop build ###.200), but still couldn't get into any TWRP.
I then followed the general process explained in this thread, albeit had to do a heck of a lot of research to understand the detail that is omitted from that (otherwise very useful and concise) original post. For example:
- how to actually use Flashtool (installing drivers and then getting hold of the right firmware from within the program);
- the difference between Fastboot and Flashmode;
- having to plug in the phone while it is loaded into the system before then flashing the selected firmware with Flashtool and ONLY THEN unplugging, switching off and booting into Flashmode.
- loading up the system after flashing the Kernel and TWRP so that I connect to computer and re-copy the erased SuperSU .zip file back onto storage, and then re-booting into TWRP and how to flash a zip file with TWRP.
Having now got a stock Marshmallow firmware rooted, my next step is to go back to the original guide I was following and try to install Cyanogen!
Thank you to all the people who have posted help guides throughout this site so that I could piece together what I needed to do - even though it has still taken me about 30 hours of my life to learn all this!
Hopefully my experience might help someone else in due course...

I had the same problem and solution is as is written here.
I had to flash Stock Firmware Marshmallow via Flashtool. After this I flashed kernel(boot) and recovery without problems and yellow icon will displayed.
Don't want to warm up this kind of old thread, but I have exactly the same issue (E8523). Would any of you mind to post their (stock) ROM versions which finally worked? I tried almost every combination that came to my mind (Customized CE1 32.2.A.0.224 => v31, several LP versions => more or less 20 to 32...).
Currently after installing the MM I mentioned the stock kernel worked, but when I flash the AndroPlus kernel (fastboot flash boot /path/to/boot.img) it won't boot up, black screen, looks like no dtb found (doesn't even try to load). This is also the message I get when I try to boot this img via fastboot directly.
I am sure I am missing something really stupid (quite new to android devices), but what?

Pro tip: hold shift and right click inside folder with recover.IMG or voot.IMG to open command prompt from that folder. Then all you have to do is type fastboot flash boot boot.IMG. I suggest trying to put a custom recovery like twrp on and flashing the xpower ROM from that, it will give you everything in one package.
Edit: fwiw I'm pretty sure custom recoveries have been able to flash .IMG fils for a few years now but I've never actually tried it. Might be worth a shot.
Thanks, but I haven't found cmd.exe on my linux machine yet^^ (I suppose wineconsole is cheating )
I know how to flash *stuff* to my phone, but that *stuff* seems only to work if some specific version of stock rom was installed previously. My best guess is the bootloader changes and supports different dtb formats on every version.
Stock Marshmallow 6.0.1 Customized CE1 32.2.A.0.224 does _not_ work for installing any version of AndroPlus kernel (tried a few...). It fails at boot (does not even load system, probably dtb).
Just in case someone might run into similar issues: What finally worked was Stock MM 6.0.1 Customized DE 32.2.A.0.224 with AndroPlus v31. It seems to be some older release (?), it says R2C instead of R9C for Customized CE1.
I could not find this information anywhere on the net (maybe its me), so for those with a slow internet connection the above version should work. You don't have to actually boot it, flashing is enough.
Thanks for sharing the information in this tread, it really helped me to unbrick my phone!
I started with Lollipop on my brand new Z3C and tried to root using AndroPlusKernel v31 / TWRP 3.0. This resulted in a softbick state, only being able to boot in fastboot mode.
After many hours struggling, an upgrade to stock Marshmallow (E5823_32.2.A.0.224) did the trick. This somehow seems ta make the device ready for the new kernel and recovery (I guess it has to do with the partitions in the filesystem).
Anyway, from stock Marshmallow I could start all over and succeeded to flash a custom bootloader, recovery and now have the ability to flash any desired rom! Thanks again.
To updrade to stock MM I used the instructions in this thread:
[GUIDE][18th Dec][4Noobs] Flashing A FTF File Using Flashtool
To set up TWRP recovery I used the instructions in this thread:
[ROM][UNOFFICIAL][6.0.1][E5823/E5803] CyanogenMod 13 for the Sony Xperia Z5C [ALPHA]
The stock rom I used for my E5823 is "E5823_32.2.A.0.224_R1C_CIS Generic_1298-5167.ftf" from xperiablog.net
Since I'm a new registered member I can't post external links
Google it and you're set!

I'm having the same problem, where did you get that MM stock version from?
And what do you mean by "you don't have to actually boot it"?
Search for XperiaFirm and Flashtool. There is plenty.
You don't have to start your freshly installed Stock Rom version "...". You just have to flash it (write it to your phone) Now you boot your phone in fastboot mode and flash your custom kernel and mod rom of your choice. Seems to be some incompatible whatever between not matching kernel versions and the "stuff" flashing installs (suspect sth like bootloader, but no idea).

I've just discovered I can boot into twrp
anything I can do to fix this from there ?

Bootloop at startup logo due to XZrecovery getting trashed

Long story - Tried to apply the latest Marshmallow rooted package for D6503 on my 6502 that was already rooted with XZ dual recovery. It installed successfully, was rooted too...but I forgot to add the patch that would fix the radio not working. So I try to reboot to recovery...and that doesn't work anymore. I tried installing TWRP recovery from the manager app, but it wouldn't reboot. Then I ran the XZ recovery installer externally, and now my phone is ****ed. Stuck at an infinite boot loop.
At this stage the only thing I can access is flashtool and fastboot, and since my bootloader is locked I can't flash a recovery that way (nor do I want to permanently lose DRM keys/camera quality as I've heard happens with unlocking the bootloader). I have a memory card and I used the option to disable loading the recovery specified on the XZ thread by adding a 'donotload' file on the sd card.
Still no use - I get a Sony logo for about 5 seconds, the screen goes dark and back to the same. At this point probably my recovery is screwed up or non existent and a bad situation has gone worse with the bootloop.
What can I try now?
@KaiserSnorezay
XZDR is still not compatible with MM, that's why you got a bootloop...
Also you can't install the "regular" TWRP with twrp manager on a LB as there is no recovery partition... it won't work and probably will mess your phone in the process.
The solution is to flash any KK / LP .ftf with flashtool (i would wipe everything when flashing as i have backups of my data/apps) , root it with kingroot or any other method you like, install xzdr for KK/LP and finally reboot to recovery and install the latest MM prerooted rom from niaboc which already has root&recovery (not xzdr btw) included. Since you have D6502 don't forget to install the baseband patch after the rom again
http://forum.xda-developers.com/xperia-z2/development/rom-official-6-0-1-23-5-0-486-beta-t3336770
Just did it exactly this way yesterday on my friends d6503 (minus the d6502 patch obviously) had 0 troubles MM, root and recovery working perfectly.
Thanks, will try this today. Is wiping data required or can i get by by just flashing the older one?

I managed to flash and root 17.1.2.A.0.314, but once again I'm unable to get any damn recovery to work. Installed XZDR, after that TWRP, in both cases it refuses to boot into recovery mode. What am I missing?

Weird, after you have your phone rooted it should be simple to install xzdr... just enable usb debugging in the phone and make sure you have the adb drivers correctly installed in your pc.
Download the latest xzdr from nut's thread ( http://forum.xda-developers.com/showthread.php?t=2261606 ) unzip it and run install.bat . After a successful install the phone should reboot to twrp automatically and it's done.
Okay, I fixed it..using Flashfire! No idea why the recovery didn't work earlier, but now finally I'm on Marshmallow. Thanks for the help!

Try what ptmaniac suggested - flash an older FTF that can be rooted (more recent ones can't), root it, install recovery and then flash the newest build.
You'll have to improve your Google-fu to find a suitable firmware and a root technique for it.

okay. you mean flashing any old firmware ( which i did and still in bootloop ) & root it. Then installing recovery for the same firmware ?
with "recovery" will i be able to get back my whole data ?
