[Sony Xperia Z Ultra] YrrchSebor:
lol, sorry for the confusion!

it's weird tho, i start on stock(after unlocking bootloader), flash the advanced stock kernel thru fastboot, boot into CWM and flash CM with no issue, it boots right up. the CM zip naturally contains the CM kernel, and it seems to flash fine thru recovery :confused:

even if it didn't work, one would just flash the CM boot image thru fastboot after flashing the CM zip in recovery? i didn't do that tho, unless i'm having selective amnesia :D
[Sony Xperia Z Ultra] shingers5:
hahahahaaha well I am not sure why it worked for you. just think if your right how many devs like FXP and Krab himself have got it wrong! why does he need to create a kernel for 4.4 and why does FXP spend so much emphasis on their kernels for their projects. yea if you flash the boot.img from aosp or cm based rom it boots fine but I always reflash anyway to avoid any issues. if krabs advanced kernel has aosp/cm support then it would work but reading his thread its for specific stock roms and not aosp/cm.
[Sony Xperia Z Ultra] YrrchSebor:
lol, i guess ignorance is bliss, and i did a bad job of reading the instructions! i do see now people saying to fastboot the boot image first, but doing that had not even occurred to me until now..... and i've been back and forth between stock and CM at least 2 or 3 times now.

for the record, i have the 6802 and am flashing CM from get.cm, not FXP, and currently my kernel version is as shown... with simply flashing the CM zip in CWM.

maybe later i'll go back to pure stock and repeat the flashing process, just to confirm..
[Sony Xperia Z Ultra] shingers5:
I'd be interested to hear your findings. My phone says 6833 as I've used the .257 stock rom which changes your version but I have a 6802. On every xperia device I posted previously the procedure has been similar so that's what I draw my experience from. I was on PA and tried going back and didn't boot but after flashing krabs then flashing stock rom worked

@imemma16 the way you install cm doesn't rely on recovery installed on phone or kernel. The get cm app preps your phone to flash cm thus not being fully reliant on what is already on your phone. You should have made that clear from the beginning as that explains why you flashed from stock to cm without need of boot.img. LOL confusion over
[Sony Xperia Z Ultra] YrrchSebor:
LOL, is that what it is? That is why i mentioned in my last post that i was using the official cm builds, in case they are somehow different. Sorry i didn't mention it sooner.

For clarification tho, are you talking about the CyanogenMod Installer on get.cm? I am not using that, as it doesn't support our device(last time i checked anyway). i am only downloading the ROM zips from get.cm(by scrolling down to the bottom to 'downloads', past all the installer stuff). Then i put the zips on my sdcard, and flash with CWM. Are the zips from their site somehow different than say, the ones from FXP?

Sorry for all this confusion everyone!
[Sony Xperia Z Ultra] shingers5:
No idea but running that cm installer on your phone does a prep to the device making it ready for cm install. Try the normal way from stock and see. Guess this has run its course now we know what you done differently. I'm out. :beer:
[Sony Xperia Z Ultra] YrrchSebor:
just as an update, i went back to unrooted stock .257, then reflashed the advanced stock kernel, booted into CWM, and restored a CM nandroid, it booted up fine without needing to fastboot flash the CM kernel. didn't try flashing a CM zip, but from what i remember that has always worked as well... will do a zip next time just to confirm.
[Sony Xperia Z Ultra] shingers5:
Serious now stop it as your just confusing things. Nandroid isn't same as flashing cm/aosp from stock. Read other thread where someone tried what you suggested and I had to advise him otherwise. The methods explained on this site came from major elite devs on xda. If coming from stock ROM you cannot use a stock custom kernel to flash cm/aosp based ROMs. Its a known fact. If it works for you then your a lucky exception. You need to flash boot.img from cm/aosp in other to flash ROM in recovery
[Sony Xperia Z Ultra] YrrchSebor:
I'm definitely not trying to confuse things, but you can understand wanting to figure this out, right? Isn't that the spirit of XDA, experimenting and learning new things, by trial and error? I am just curious what i could be doing differently, and if we knew that, perhaps it could add to the knowledge of this device?

But anyway, you and i are the only ones going back and forth here, so i guess I'll just wait and see if anyone else can reproduce my results. I have used official CM zips and Pacman at one point, but haven't tried the others. I unlock the bootloader by manually flashing the unlock thru fastboot.
[Sony Xperia Z Ultra] shingers5:
dont get me wrong i am glad that you are looking into this but its no good if everyone else gets stuck after doing it that way, if on yours or another this doesnt happen it doesnt necessarily benefit everyone which is my point here. these instructions handed down from the elite devs on here are guaranteed to work not just for you but everyone else and have done across many devices. thats my point...............i unlocked my bootloader the official sony way which same as what you did! someone else tried what you said and got stuck so its not for everyone hence it cause confusion and that in itself doesnt help bud.............quite opposite
[Sony Xperia Z Ultra] LordManhattan:
Guys, i'm confused.
[Sony Xperia Z Ultra] shingers5:
Lol don't start. No confusion. If your on stock and wanna go cm/aosp you need to first flash the boot.img from that ROM zip then flash ROM in recovery. Simples.
[Sony Xperia Z Ultra] [NUT]:
If you have time to burn, can be meticulous in testing and have quite some experience in flashing/restoring your phone and want to help me by testing my future XZDualRecovery releases, send me a PM with your Google hangouts handle/Gmail address.

[MENTION=3843529]gregbradley[/MENTION] has been doing an amazing job at testing sofar but this has been limited to the Z1 build. I would like to expand my test team a bit for both the Z1 and have one for the ZU.
[Sony Xperia Z Ultra] [NUT]:
[XZDualRecovery] 2.7.41 BETA released!

:victory: Yay! :victory:

The time has finally come, I've found the perfect solution to the issues haunting the Z1 and Z Ultra recoveries...

So I'm proud to announce the release of the FIRST TRUE BETA of XZDualRecovery with official support for the Z Ultra and Z1, 2.7.41!

Please do test and report any problems you might find in THAT thread!

A HUGE thank you to [MENTION=3843529]gregbradley[/MENTION] for letting me destroy his ROM on more then one occasion to make it work in the end, your help was invaluable!
[Sony Xperia Z Ultra] cocchiararo:
Hi

If i want to revert my Z1 to like it was before installing the recovery, should i use the "restore" or the "remove" from that thread?
[Sony Xperia Z Ultra] [NUT]:
You really wish to remove it or are you planning on updating to the XZDualRecovery release there?
[Sony Xperia Z Ultra] shingers5:
good news that for lock bootloader guys

just a shame we cant get recovery that flashes any rom be it stock or aosp/cm based, can't wait when we can have kernels with support for both stock and cm/aosp based roms.
[Sony Xperia Z Ultra] cocchiararo:
I am hoping for the 4.3 update soon, so I need to know how to remove it for the OTA and then install the new version after the ota

Enviado desde mi C6903 mediante Tapatalk
[Sony Xperia Z Ultra] [NUT]:
Any version of XZDualRecovery, be it the development versions here or my baseline packages, do not interfere with OTA. Only unlocking your bootloader will do that.
[Sony Xperia Z Ultra] cocchiararo:
i could have sworn that someone said in this or some other thread that it did... even better then, i just need to update it :P
[Sony Xperia Z Ultra] shingers5:
yea having custom recovery on phone will interfere with updates as device boots into a recovery state to flash. if custom recovery is on the update will fail. you need to revert to stock before doing any updates
[Sony Xperia Z Ultra] cocchiararo:
uh, i was right

This brings me to my previous answer.

Revert or remove? (from those 2 options in the dev thread)
[Sony Xperia Z Ultra] [NUT]:
I'm assuming you have your first Xperia device?

These locked bootloader packages work a LOT different, no such things custom recovery issues compared to Samsung or HTC...
[Sony Xperia Z Ultra] shingers5:
wouldnt know for sure but i'd say revert as that sounds like it reverses whats been done.

---------- Post added at 07:52 PM ---------- Previous post was at 07:42 PM ----------

assume away........nope ive had them all but all bootloader unlockable. i did read somewhere that i did cause issues but maybe i was wrong! he can try and see cant he and let us know. either way i was trying to help............
[Sony Xperia Z Ultra] techpal:
Custom recovery doesnt affect OTA, its unlock bootloader which does. Check here post no.74 http://xdaforums.com/showthread.php?t=2556992&page=8
[Sony Xperia Z Ultra] LordManhattan:
I proved you wrong :p I was on Omni 2 minutes ago, and i had to go back to stock 257. I booted up recovery, chose my 257 backup, aaaand it restored it. It also booted just fine :p Confused? Me too.
[Sony Xperia Z Ultra] shingers5:
well if the backup was done with the same recovery you flashed omni with then yea thats fine..............if you had flashed the new stock boot.img then tried to restore that backup then issues may have arose. i thought you wanted a clean .257 like me without any mods
[Sony Xperia Z Ultra] iBuzman:
^^ to offer my two cents worth... Every single time I have restored a nandroid, whether from cm, pa, stock, modified stock etc, it has booted fine AND returned me to the kernel and recovery that was present in my nandroid :D - doesn't matter if on adv-stock-v5 based recovery or the any of the cm boot.imgs I've fastboot'd. Not disagreeing with what you guys have experienced, maybe I've always flashed "compatible" stuff :)
[Sony Xperia Z Ultra] shingers5:
I am beginning to realise that this might be the slight differences in the c6833 and the c6802. Like I said something that works for a few doesn't benefit all hence why the old methods are better as work for all
[Sony Xperia Z Ultra] martin132014:
I want to know, im on stock rom with dual recovery ver 257.....when im on recovery, why there is no option to backup in external sd card....i can only choose and see it only in internal sd card....even if a zip file on external l, the recovery cant see it....
[Sony Xperia Z Ultra] StarRider:
You don't say.. ?!

You can assume it's my first Xperia, or rather the first Xperia I'm flashing sh*it to, and I've noticed that this bootloader-**** is a lot different, and I'm somewhat confused here, so forgive me for what I know must be a very n00b question, but what difference does locked or unlocked make with regards to flashing sh*t ?

I have a locked bootloader, and this seems a lot mor unstable or unpredictable than the Samsung's I've been flashing "houndreds" of times, in that I never actually know if I will have the same recovery as last time, if any at all, when I reboot. I also seem to loose root almost every time, at least the recovery tells me that almost every time, and asks if I want to fix it.

:eek:
[Sony Xperia Z Ultra] shingers5:
What file format of ext sdcard?,I used same rom .257 and used cwm to backup to external sdcard and even restore back. I don't use twrp on this device at all. I know it works as I have done it more than once. If using twrp try cwm or see if sdcard is fat32 as not sure if ext 4 is supported etc
[Sony Xperia Z Ultra] [NUT]:
The biggest difference in Samsun/HTC compared to Sony is their recovery partition, which is something our Sony phones simply do not have. Because of this, your recovery has been installed in the ROM instead, so every time you flash a ROM, you end up having to flash/install the recovery again as well, unless one has been integrated in to the ROM you where flashing.

The only 3 things different between locked and unlocked bootloaders (aside from the camera bug on the Z1) are these:

1: When locked, the kernel needs to be signed by Sony to have it accept it and boot the device, unlocked it will boot any custom/stock kernel you throw at it, if created for your device.

2: When locked a service called RIC is trying to prevent you from modifying your ROM by rebooting your device as soon as you try to remount the system partition or start writing to it. Unlocked this service just runs but does nothing.

3: When locked, you can only flash ROM's which are based on stock Sony ROM's. When unlocked you can run anything you like, as long as it has official support for your device.

Custom kernels tend to have a built-in recovery, which is embedded with the kernel in the boot partition, which prevents you from losing your recovery when flashing different ROM's.

On my XZDualRecovery thread I have a flashable zip installer, which you can flash straight after flashing a new ROM to restore recovery. Note that it's meant for STOCK based ROM's only and make sure you grab the BETA package for the Z1 or ZU to use it.

Hope I've helped you wrap your head around the 'Sony way of flashing sh*t' ;)
[Sony Xperia Z Ultra] shingers5:
Take it easy bud. Locked bootloaders mean you can only flash stock based ROMs as your bootloader restricts kernel flashes other than stock. When flashing a stock ROM on locked bootloader try flash one with a recovery kernel included or flash recovery zip after ROM flash. Most stock kernels don't have recovery attached to them. Unlocked bootloaders means kernel flashes, custom roms aosp/cm etc
[Sony Xperia Z Ultra] martin132014:
Not sure if it fat32 or ext 4...but will check....and also i have check cwm and twrp doenst read my external sd....so if my sd card is ext 4, i need to change it to fat32 right...?
[Sony Xperia Z Ultra] shingers5:
yea you will bud as many have posted this error with ext 4..............so just check and change to fat32 and you be fine
[Sony Xperia Z Ultra] martin132014:
I test it on my 2gb sd card and change it to fat32 but cwm still cant read my sd card and unable to backup to external....try to change backup folder on cwm but only read sd card, thats internal sd card. No other else...any idea's...tq
[Sony Xperia Z Ultra] shingers5:
is your bootloader locked or unlocked? if unlocked try a different recovery kernel and boot into recovery to check................i have never had that issue so its hard to offer advice on mate
[Sony Xperia Z Ultra] martin132014:
Im locked bootloader...me too have never have any issue like this on other models....ive used the same sd card and never have a problem....if still cant solve, maybe i just stick to internal for my backups... Tq
[Sony Xperia Z Ultra] shingers5:
think your recovery might be the issue..............have you tried the one posted by krab for locked bootloaders? also check out the new one i linked before. cant see why it wont work unless your card slot has issues? what rom are you using now?
[Sony Xperia Z Ultra] martin132014:
I think im using the one you suggest in the other forum about locked bootloader recovery....the second link....im using stock rom 257....unmodified...
[Sony Xperia Z Ultra] martin132014:
I've check and isnt that krab cwm is for z...will it support zu....tq

Just try and on first boot it go to recovery but when try to boot again, i can't go to recovery...try to push up and down several times but no luck....i have first remove dual recovery and just flash this one....is there something i miss....
[Sony Xperia Z Ultra] shingers5:
sorry for late reply...............you need to wait for green led then hold vol up till recovery pops up. don't need to push multiple times. sony logo then led will light up green so hold vol up for cwm or down for twrp

Yeah, i know this but no green led on boot...thats why i test to push multiple times to check but still no luck...but never mind....i just got one recovery work for me xzu recovery v4....non touch cwm and twrp.....6.0.xx...a little long to backup but it work for me....thanks for your help...

Hello to all of you,

I have some very sad news especially for Xperia Z1 and ZU users..

But first I wanna give a lot of thanks to all of you for the great support and confidence in me throughout my development times here on XDA, I've met some wonderful people and learned a lot. I know people respect me and it's given me a great feeling of satisfaction.

I have some really difficult issues/situation to deal with in real life now, I can't keep running away from it. I'm sorry to announce to the entire community I'll stop development right now.

I don't know if and when I'll come back. I hope I can come back, but it all depends on my personal situation. Please don't sent me a lot of pm's about the issues. Thank you.

Regards to all of you,

Krabappel2548
