Hi All,
I am new to the forum and new to rooting. I did loads of reading and thought that I would give rooting a go on my Sony Xperia Z Ultra. After rooting, and doing dual boot install I downloaded Dirty Unicorns 4.4.4 and Gapps. Booted into recovery and flashed the two zip files. After booting up the rom, it keeps crashing and giving a systemui fail / crash message. So I cannot do anything with the rom because the message comes up a second after I close it.
Not only that, there is now no custom recovery on my phone. Has anyone else been in this situation or can anyone please let me know what I can do to either flash a custom recovery?
I have also tried connecting my phone to the Flashtool to flash the stock rom, however as soon as I connect my phone to my pc it boots the system up and doesnt allow me to go into flash / fastboot mode.
Please help!
Thanks,
RJ

Thanks! Didnt know where to post.
Recovery should be included in the ROM (I've not flashed it though to test)
press the vol. up key just after booting when the LED turns purple should do the trick.
Do you want to load another custom ROM [1] or go back to Stock Sony [2]?
[1] Download custom ROM, flash boot.img in fastboot, flash ROM from recovery with wipes
[2] Download a FTF and flashtool (http://flashtool.net), flash FTF - fully clean Sony system again

Can you clarify what you mean by "doing dual boot install", are you referring to the multirom mod or something else.
Did you unlock your bootloader?
Because I see no mention of that and when I flashed scrubbers port of kitkat via twrp it bricked my ultra and I had to buy a new one.......

Hey how to unlock the bootloader in sony phones and after its unlocked how to go to fastboot mode..
After trying a few custom ROMS, I decided to revert to full stock. CM12 did mess up with my recovery : it installed Cyanogen Recovery, even if I didn't want to and even if the option to install it was disabled in the dev settings ! Since then, I can't flash another ROM or if I can, it will be buggy for no reason (apps not working, etc.).
So I decided to revert to stock with a proper FTF file using Flashtool in flashmode...however, it won't work !
It won't flash the rom properly : the flash last 3 seconds. It says it went fine but as you can imagine, in 3 seconds, it didn't flash anything really. As a mater of fact, if I'm booting the tablet, I'm still under CM12.
Is there a way to revert to stock in another way ? I tried using Fastboot, after extracting the .ftf file but same issue : it looks like it's flashing but it's way too short to flash the system.
Any idea ?
Screw CM12 anyway, forcing their crappy recovery is a **** move.
Hello,
I have a huge issue with my Z2. A month ago, I decided to try MIUI, after being bored by CM. And like a complete 'tard, I also downloaded DooMKernel because why not. New rom, new kernel, more ways to tweak my phone ! yay !
But no. I misread DooMLorD post, and didn't saw that it was ONLY for stock roms.
I discovered that after seeing my Z2 stuck in bootloop... wat.
So, I reflashed my previous CM11 rom (original ZIP, not a backup, via CWM). And it worked. But the bootloader decided to magically disappear. wat².
At the time, I didn't bother because I was in a rush (I am really stupid) and because, you know, if it works, don't fix it.
But as I write that lines, my phone won't send or receive messages, and have a HHUUUUUGE battery drain (Google Play Services making CPU run @100% all the time).
So I tried to install TWRP via their app, which is crashing at launch (my ROM is really, really f*cked up).
I don't know what to do.
Flashing a stock rom with Flashtool? Will it hardbrick my device as I unlocked my bootloader?
If needed, I have my TA backup.
If you could help me to get a recovery back, that would be highly appreciable.
Thanks !
if you are on unlocked bootloader, this should do it :
- flash stock ftf using flashtools
- flash @AndroPlus kernel using fastboot
- boot into recovery with vol down or up button (one is twrp other is cwm)
from here you can flash CM back and reboot the rom, once you fully boot go back to CM recovery and restore your backup.
good luck, good thing you have a backup before all the mess happened.
Thanks ! It worked.
I had to flash the kernel before the .ftf because Flashtool was giving me a error message.
But I now have a bootloader !
Many many thanks.
It seems a bit trendy to mess with the recovery, resulting in a brick or bootloop.
Just making a new thread cause my case is a bit different.
I was on Existenz 4.7.0 when I decided to flash 5.0.
Wasn't a clean install, resulted in some app fc'ing and restarting, so i went back to trwp and used my backup, keeping in mind to come back and make a clean install when I can take the time it needs.
Made a few backups today and wanted to start the trwp backup when I realised that I wasn't able to enter recovery.
Installed the trwp app, which wasn't able to reflash the recovery.
So I read another posting and I decided to delete the chargemon and rename the chargemon.stock, but that wasn't that smart, I decided later.
So back home I downloaded the dual recovery software from NUT's website to totally reinstall the recovery. After some ADB trouble I managed to get everything running, the batch file installed the recovery, everything looked pretty, at the end of the process the Z2 rebootet and e voila, I'm stuck in bootloop, clueless.
When I power the phone you can feel the first small vibration, then the Sony logo appears, stays, and it reboots.
Reset Button, powering on and holding Volume up isn't doing anything, so is Volume down.
What can I Do?
I know I made a few mistakes, but help is still needed!
Bro, Please read carefully before installing recoveries.
Nut's Recovery is NOT for Marshmallow. and it will cause bootloop and same problem you encounter here.
Only Solution is to flash via flashtool and re-root.(personally i would flash a kitkat .ftf then root it with any of the available methods. you can try kingroot it is the easiest) after that install Nut's recovery and flash your MM rom which will come with its own working recovery.
Oh, ok, so thats the cause. Didn't know that, shame on me.
So Existenz 5 messed up my recovery and maybe the silly try of reflashing killed it totally or just the bootloader.
So I will try to setup a Win7 PC and setup flash tool properly (didn't seem to work on win10)
Thanks for that finger point I the right direction
Flashtool works on windows 10 no problem for me.
Just install the right drivers and install 0.9.18.6 version of flashtool and try different drivers it shall work
Will do, thanks a lot. Seems to me that I had a 4.7 Existenz Rom with bootloader/recovery from MM, which I destroyed.
Is it possible to reflash the old bootloader? Or will flash tool spare my datas on internal SD card?
why to flash a boot loader?? is your device unlocked bootloader??
It's locked.
So it can't be a broken bootloader?
So it's just because the recovery is messed up?

yes bro don't worry.
It seems that you are new to sony or you re coming from samsung or any other device with recovery partition.
By default, Sony doesn't have a recovery partition like in samsung. that is why developers made the recovery a part of the system (your ROM) the chargemon files are the one responsible for the recovery. so when you install a recovery it is like you are installing a system application which can be messed up if it is not compatible with your rom version.
PS:Be carefull never wipe the system partition from recovery and restart your phone before installing a new rom because if you restart without having installed your rom your phone won't have a recovery(part of the rom) neither a system----> Bootloop and need to reflash.
you can unlock your bootloader and make a recovery partition and install aosp roms. but on sony once you unlock your bootloader you will loose a lots of features and camera enhancements. so better keep it Locked and use stock based roms like existenz and MIUI roms which are stock based.
I hope i have been able to clarify all
OK, makes sense.
Seems like I'm still pretty new to Sony. Came from Samsung last December, just got enough knowledge to flash and improvise, quick and dirty.
So if I could get hands on my old chargemon file, (from when I didn't tried to install Existenz 5) I may get the Z2 running again?
Of course a pretty clean install afterwards.
Just asking, cause of backup reasons
Edit: I knew that unlocking the BL has a few disadvantages. I'm happy with Existenz but now I know a few things more, thanks michel090428
it is very difficult now even if you have the chargemon file. i don't know what could be messed up with the system. go for a clean flash it is the most safe way to do it.
Read this guide if you want a help with flashing it is very easy and detailed. and remember it is better to flash kitkat .ftf as it is easily rootable.

Hey folks, I'm back again!
Managed to setup a Win7 PC, installed the correct drivers, setup Flashtool, found correct ftf file and so on.
Problem is that I'm only able to get into fastboot mode with my Z2, for me it seems like Flashtool won't work when the device is only in fastboot mode.
What can I do?
why you can't start your device with flashmode?
You need to shutdown the device then when flashtool ask you to start in flash mode you press volume down(keep pressed then you plug in USB cable and it should start in flash mode directly.
have you tried to follow the guide i posted in the first page? where are you stuck? which step?

Was a bit tricky, did the 'vol down + plug in' thing several times and it worked suddenly, flashtool flashed the ftf. Now it's FCing several tasks while it would do the android setup. Trying to flash a 4.4.2 ROM now, thanks for patience and help, appreciated this!
WIPE DATA

You re Welcome Bro,
Concerning the FC You need to check the WIPE DATA option in flashtool i think it will solve the FC's
I'm with 23.1.A.1.28 now and it's fine. Just need to get root, there should be an exploit but it's not working for me, reasons unknown. Going to have a look at it later. Want to flash Existenz, that's the goal.
Bro , Use KINGROOT it is able to root .28 firmware.
there is a thread here for kingroot.
well i flashed the unoffical version of cyanogenmod 13 and all it did was drain my battery.So now i want to reflash stock rom and have no idea how.I tried using flashtool with various ftf files for the m4 aqua but am still unable to do it. Im rooted and bootloader unlocked please help
Use flashtool and any stock ftf. If flashtool fails flash some partitions- flash system only, then data partition.
