Yes. The Z1-lockeddualrecovery2.8.9 flashable for some reason does not worked, but the installer was successfull.

1st flash the ROM and try the flashable zip and after that reboot.

I see now there is Z1-lockeddualrecovery2.8.10 available.

Good luck ;)
[Xperia Z1 Android Development] cashflow67:
Hey man. I can't install your recovery using 2.8.10 installer on Stock KK .157 rooted ROM. What happened? 2.8.3 was very good :(

It looks normally installed with installer, but first boot is not on recovery, it boots phone normally. I tried to press vol up and vol down but nothing changes. On menu there is ndr utilis app, I open it I switch between recoveries but it doesn't boot in recovery :(
[Xperia Z1 Android Development] yuzrawk:
downgrade to 108- root with newroot then go to recovery flash lollipop official rom, flash nuts latest version(flashable) with recovery then flash ftf with flashtools. now u got lollipop+nuts recovery :)
[Xperia Z1 Android Development] cashflow67:
No, For two days I have tried everything, and today I wrote on Nut's recovery page and he came back his 2.8.3. So there is a problem on 2.8.10 with KK .157 rooted ROMS. but with 2.8.3, it works like a charm :) Thanks nutsss
[Xperia Z1 Android Development] goku16:
confirmed, 2.8.3 works if anyone is having issue install the dualrecovery
[Xperia Z1 Android Development] :
2.8.10 works with the Lollipop update
[Xperia Z1 Android Development] Aaron_035:
Did you just flash it over 2.8.9 or installed in from a PC?
[Xperia Z1 Android Development] xshunin:
I just used the PC installer on a pre-rooted stock 5.0.2 ROM. Worked! Just tested.

Edit: If you have attempted it with an earlier version it might not work because there are older files in the temporary directory. Delete the /data/local/tmp/recovery folder for it to work.
[Xperia Z1 Android Development] lapuckire:
Installed 2.8.10, wasnt working, so I installed 2.8.3 - it is working but twrp doesnt work - it loads the page with the buttons, stay so for 10 seconds (twrp is not responding in this time) and reboots. CWM works fine

using Stock KitKat .157 rooted, LU.

Any ideas how to solve?

EDIT: ok, I tried 2.8.11 Attempt 3, seems it works fine ;)
[Xperia Z1 Android Development] potencias33:
What differences advanced nut kernel vs cocore kernel?
[Xperia Z1 Android Development] [NUT]:
Xzdr kernel is a repacked stock or custom kernel, which includes triple recovery and NDRutils.
[Xperia Z1 Android Development] potencias33:
But your kernel is only in flasheable zip version?

I have looking for boot.img in your download page and not found.

I like use flashtool for latest firmware and after fastboot kernel and have your recovery....

Thanks

Excuse my bad English
[Xperia Z1 Android Development] [NUT]:
It's a flashable updater, the boot.img is stored in the tmp folder inside the zip. You can fastboot flash that to get recovery and then flash the zip to install NDRUtils.
[Xperia Z1 Android Development] potencias33:
Ok thanks.

I'm gonna try it now that unbranded Spain us rolling out.

Cheers
[Xperia Z1 Android Development] cashflow67:
I'm at Lollipop, rooted, your 2.8.10 recovery installed. How can I update to 2.8.12? with installer or flashable zip? I will get sony logo error?
[Xperia Z1 Android Development] [NUT]:
No Idea if you get an error... I still don't know what causes that!!

But you can use the flashable, the users who reported their findings on the DevDB are plentiful and all say it's working fine.
[Xperia Z1 Android Development] juanpirulo:
Sorry . I just try attempt two. I set on false before flashing the updated zip and nothing changed still remains false.

mmmm should now add DRSETPROP dr.keep.byeselinux true in line 133 of dualrecovery.sh?

yessssss now i think its ok. I will check a Little more tomorrow i need a rest. thankkk you very much [MENTION=4904057][NUT][/MENTION]
[Xperia Z1 Android Development] mgh1982:
Thanks for the flashable zip. Does it have double tap capability???
[Xperia Z1 Android Development] [NUT]:
No, it's still a sony kernel, no new features except xzdr functionality.
[Xperia Z1 Android Development] cashflow67:
I think flashable zip changes something about chargemon. Because Rockz1K's latest recoveries zip can update recovery very easily.
[Xperia Z1 Android Development] juanpirulo:
Probably the same I had got with mine I gess. [MENTION=4904057][NUT][/MENTION] Definatly I think now is working correctly adding " DRSETPROP dr.keep.byeselinux true in line 133 of dualrecovery.sh " but now i gess i will have to do this modification anytime you update the xzdualrecovery isnt it?. cheers
[Xperia Z1 Android Development] [NUT]:
Actually, yes and no both:

It's wise to make sure that your ROM's flashable zip is modified to do so. Once the setting is set in XZDR.prop it should not change unless the file is removed.
[Xperia Z1 Android Development] [NUT]:
well... maybe it does, but then the next Attempt version should fix that.

lost recovery suddenly

I lost my dual recovery suddenly when I wanted to flash a new Rom. The same thing happened when I was on 4.4 and I do not have a PC right now since my laptop guzzled a can of beer cos of a stupid friend. Is there any way I can flash a recovery without a PC? I'm getting my laptop on Monday anyway but would like to know if there is a way to do it. I'm on stock lp (Venkat kamesh's) Rom, rooted and LB. I tried to hold power and vol up and every other thing while researching through xda and Google but I can't seem to get an answer. The phone has no recovery and I've tried flashing it with Flashify and #Rashr but to no effect. Any help is appreciated.
[Xperia Z1 Android Development] D_Vovan_238:
?

Can't set Unsecure Recovery Ramdisk, cpio compressed .

It's now unsupported?

And all is correctly set in XZDR file.

With old version, and with CrisKelo Rom all work perfectly this way.

Sorry for my bad english, I'm Ukranian ;)
[Xperia Z1 Android Development] [NUT]:
No, you should flash xzdr again (using the flashable package) after flashing any rom unless it includes xzdr by default.

Sorry mate.

No, it has never changed to be honest... It should (still) work if it did in the past...

What version of xzdualrecovery did you install?
[Xperia Z1 Android Development] D_Vovan_238:
:)

2.8.12, it was working perfectly on 2.8.8 with KK, but its rebooting on 2.8.12 with LP stock.

It's the TWRP 2.8.4 recovery ramdisk, extracted from your 2.8.8 version and uncompressed from .lzma.

I wanted to make Backup with this version of TWRP and then add Stock Based LP from backup like secondary rom.

On my primary rom I'm using 2.8.4 Multirom TWRP.

So can't restore Backup made with 2.8.6 TWRP :(

---------- Post added at 11:43 AM ---------- Previous post was at 11:38 AM ----------

And can't even restore backup made with Philz recovery in TWRP mode.

Thanks for your work, and for answering :)

Sorry It's 2.8.4 Multirom TWRP extracted from Trinity Ultimate Multiboot Kernel.

---------- Post added at 11:58 AM ---------- Previous post was at 11:43 AM ----------

Will try too extract 2.8.4 .lzma from your dual recovery solution maybe then I will add stock based LP for my stock based KK ;)

Install MultiRom Manager from the Play Store and it will flash TWRP, as long as you are running a kernel with the kexec-hardboot patch.
[Xperia Z1 Android Development] ravishmahur:
sorry , i m a noob..

how can i check if i m running a kernel with the kexec-hardboot patch.
[Xperia Z1 Android Development] zgomot:
Run MultiRom Manager and check under Status if your kernel has that patch. If it's green you're OK, if it's red you need to do some searching and find a kernel that does. If this is still too complicated you need to do some further reading.
[Xperia Z1 Android Development] ravishmahur:
It is red :/

[Xperia Z1 Android Development] Fladder72:
I had exact the same problem by using the batch file under windows. After copying the install.bat in to file folder and executing it there, problem was solved. Maybe the pathes in installer script/batch to "files" are wrong....
[Xperia Z1 Android Development] ptoner:
I tried that on OSX 10.10 and Windows XP Pro. Did not solve it for me sadly.

I am on Z1 - 14.5.A.0.270 - Rooted using Kingroot - Think I Updated Busybox after also, if that causes issues?

Seems liek the directories arent working and the file naming etc have been changed.

PS I have rooted and installed ROMS etc many times on this phone, so not a relative newbie.

Attached Windows XP screenshot showing the normal uncompressed folder install location.

Also moved it into the "files" folder, no luck.

NEEDHELP

I soft bricket my device by flashing something wrong (not ROM, by mistake)from PHILZ TOUCH RECOVERY.

Now the phone is stuck in SONY logo . I can get to fastboot .What are my options? Should I flash ftf or is there im option to boot something with fastboot, get to recovery and flash rom normally?
[Xperia Z1 Android Development] [NUT]:
Use the kernel builder. Flash kernel from the zip you download. Done.
[Xperia Z1 Android Development] [NUT]:
Sony's have no regular recovery, so you need recovery integrated in the kernel or on system. As you have unlocked your bootloader, it's best to use the kernel version.
[Xperia Z1 Android Development] [NUT]:

[YOUTUBE]S0BamrsglUE[/YOUTUBE]

EDIT:

Really, if you still don't understand how to flash a kernel, you should relock your bootloader and forget about modding.

Guides are for dummies, an unlocked bootloader isn't.

Hi

Does it work on android 5.0.2 UB .270 build?!
[Xperia Z1 Android Development] TheNewbieRooter:
Hello I have a question.

If I have XZDualRecovery and a custom ROM ( Lollipop / .270/ Xperia Z1 C6903) with locked boot loader can I simply use Flashtool to Unlock my bootloader without any other steps (e.g reverting back to stock recovery)
[Xperia Z1 Android Development] [NUT]:
Yes, you can. Remember that unlocking the bootloader wipes data and internal storage...
[Xperia Z1 Android Development] TheNewbieRooter:
So I can literally just connect in fast boot mode open up flashtool and use the 'Unlock' feature to unlock my bootloader? Without loosing XZDual recovery?

Sorry but I've heard bootloader unlocking is dangerous so just want to make sure with you experts :)
[Xperia Z1 Android Development] [NUT]:
Xzdualrecovery is stored inside system, so you will most certainly not lose it.

If you have an external sdcard then the next warning is not even needed, but for completeness:

If you use xposed and need to keep dr.keep.byeselinux set to true, then you MAY get a bootloop after unlocking.

In that case, create a backup of the xzdr.prop on your cache partition before unlocking (if it exists, which it will not when the sdcard is available) and put it back using recovery if you do end up in a bootloop.

Just thought I would give a heads up that this does not work on windows 10 64 Bit (Fails flat out to create directories) but worked fine on Windows 7 after an hour of banging my head against a wall
[Xperia Z1 Android Development] [NUT]:
Uh, folders, where? On the phone or on disk in Windows? Because if that's the case, it might be because of a anti virus thing stopping you from extracting the installer.

It contains a root exploit, so it trips some of the A/V tools... Sometimes on downloading, sometimes on extraction. Can you check this some more and report your findings? Thanks!
[Xperia Z1 Android Development] matcho13579:
No problems for me on Win10 64bit
[Xperia Z1 Android Development] KouenHasuki:
Him, odd... My win 10 was setup the same as the win 7 with the same driver and nether was using any anti virus. But only my win 7 machine could flash it.

My win 10 machine was opening a connection OK, but refused to create the directories or push data to the phone. They was both authorised by the phone too
[Xperia Z1 Android Development] [NUT]:
Which adb driver did you use? The one from Sony or the one included in FlashTool?

[MENTION=3845051]matcho13579[/MENTION] as well.

Not working on my XPERIA Z1 (C6903)

Hello, today I tried to install this dual recovery on my XPERIA Z1 with no success :( at the end it says: "Installation finished. Enjoy the recoveries!" but nothing happens device remains unchanged in any way. After restart i could not get into recovery by mashing both volume buttons, green light didn't light up and it booted to the system. Is it yet not supported on 5.1.1 or am I doing something wrong??

[Xperia Z1 Android Development] papperlapapp:
I now successfully repacked the kernel from cm-12.1-20151011-NIGHTLY-honami boot.img for C6903 and I can get into the dual recovery.

But, when trying to get into the OS, I see "Android starting" "starting apps" and this takes ages now, it has not finished yet. It seems the boot process hangs. Before installing XZDR booting into cm-12.1-20151011 worked properly.

After waiting countless minutes, the device gets stuck. As I said, installing XZDR with repacked kernel worked, dual recovery works. But, XZDR now gives me a stucked device... BL surely is unlocked.

Thanks for any advise!
[Xperia Z1 Android Development] [NUT]:
Did you also flash the zip or only the boot.img?

If you flashed the zip, enter recovery and remove /system/app/NDRutils and try to boot again.
[Xperia Z1 Android Development] papperlapapp:
I tried both, boot.img and zip, both make the device hang. This is now what I did, I installed CM12.1 boot.img, booted, manually wiped the Dalvik/ART cache folder and shut down.

Then I installed XZDR from boot.img I created from CM12.1 nightly. Installed finde, XZDR is available.

But, the device still hangs at "Android is starting".

Thus, wiping the cache and removing NDSUtils did not help.

Well, at least I now know how to install XZDR for rescue purposes, for every day use I need the CM12.1 recovery to get the OS booting.

Thanx
[Xperia Z1 Android Development] papperlapapp:

Yes. But I think to new Android security the exploit doesn't work anymore on newer android versions. For 5.0.2 I had to first root the device to get the Recovery installed.

If you are rooted than download the windows installer and install the Recovery again. If you aren't rooted than you are out of luck.
