D6603 23.4.A.1.264 Lollipop 5.1.1 downgrade - Xperia Z3 Q&A, Help & Troubleshooting

Hi all i just bought this mobile and i was curious to know if it was possible to install a custom rom.
I saw that the downgrade is the only solution to root and install custom recovery.
In my case i wish to know which file i have to flash with flashtool.
Thanks all

Yes

Update:
Downgrade --> Done
Root and DualRecovery--> Done
Backup DRM TA --> done
Bootloader Unlock --> Done
I'm trying to flash custom room rebooting in Teamwin recovery the flash goes perfect but after when i reboot the Z3 it goes in boot loop and i can enter only in the recovery the Z3 won't start at all.
I've tryied with 2 custom ROm and the original rom lollipop rooted and patched.
What i do wrong? I just put the custom rom in the Micro-sd card and i flash it using the teamwin recovery (before i wipe cache and Dalvik). Do i have to flash before the boot.img?
Thanks

You are either flashing an incompatible custom ROM or your boot loader is not unlocked.
Flash a stock FTF again, then goto the dialer and dial *#*#7378423#*#* then goto service info, configuration and post here what it says in the rooting status.

Well, neither of those require an unlocked bootloader, but that should not make a difference.
What boot.img are you flashing, both of those ROMs require a stock kernel.

at moment i have a 4.4.4 stock rooted http://dl-1.va.us.xda-developers.com/3/6/5/9/5/7/4/Screenshot_2016-02-25-15-46-09.jpg?key=4YW3-mNtbisUcXLWsSrQ_g&ts=1456411770
Which procedure i have to follow to flash a custom ROM?
i normally copy the rom zip on the external micro SD card
i go to teamwin recovery i do a wipe and after i do install
The install finish and i click on reboot
DO i have to do other steps to flash the stock kernel?
i didn't flash any boot.img and kernel until now
UPDATE
problem solved i flashed the stock 5.1.1 kernel before to flash the rom and the bootloop disappeared.
Now i'm with the custom Mod there is any possibility to restore the DRM functions with the custom rom?

Well, if you only want to stay on these stock based custom rooms there was no need to unlock the bootloader. You only need that for truly custom rooms like cm or aosp.
If you want these rooms with drm keys then do this.
Restore your T A backup. This will relocate your bootloader
If this results in a boot loop, then flash a stock ftf, and do everything again EXCEPT do not unlock the bootloader this time

[Q] loading stock firmware without screwing custom recovery

Hi... im currently running
CROMi-X v5.2.2, which is based on rom 10.6.1.27.5 with twrp 2.5.0.0 and my bootloader says is the one that came with us10.6.1.15.3-20130416...
To install omni kitkat, im been asked to have the latest bootloader, to avoid screwing up im planning on insalling the latest stock from asus...
However, each time i install a stock through twrp or cwr, the new image not only updates the bootloader and deletes all my data, but rewrites my recovery, for which then i have too reupload using fastboot to upload the recovery...
Is there any way to make sure i dont loose the recovery after flashing a stock firmware... or a way to flash the recovery from the recovery before rebooting after flashing the stock?
Thanks everyone!

Flashing the stock ROM reverts the tablet back to stock, so the recovery must go. Luckily, the bootloader you are on is compatible with the KitKat recovery (10.6.1.15.3) so you shouldnt have to flash the stock ROM at all. If you were on 10.6.1.8, you would have had to upgrade.

[Q] Official (not manual) lollipop OTA on unlocked moto g xt1033

So, the situation is I have moto g xt1033 with :- unlocked bootloader, rooted, stock rom 4.4.4 kitkat (i mean no custom rom). and fastboot flash mode 41.13 2014-06-16 and philz touch 6 clockworkmod v6.0.4.7
I want to know how to update to lollipop with official OTA update (not manually or sideloaded)?
Why I am asking this?
I got the prompt of official OTA available on my phone and then i clicked yes and downloaded the update. But when i clicked on install, it went in bootloop. It boots on the philz recovery mode and then nothing happens just restart again whatever i select.
As of now, as I backed up, I recovered to the before state of the phone. Do I need to lock the bootloader again or what? The official OTA update is not for me? Then how to get lollipop? I read the soak test etc threads but why not official update ?
Locking the bootloader won't do anything,so don't lock it
Ota update requires:
1.Stock firmware(unmodified and unchanged or tampered)
2.unrooted
3.Stock recovery
That probably happend becuZ your KitKat firmware was modified and you have custom recovery,root..
So just reflash the stock firmware
Do that on your own risk as failing this might brick your phone
Thank me if I helped
Thanks mate for reply.
1. I have stock firmware KK 4.4.4 (though xposed framework & few modules are installed currently)
2. Rooted
3. What is stock recovery? (m noob here)
And i guess reflashing the stock firmware wipes out all user data & apps, right?
Any other alternative which does not wipes out my data?

Actually there is no other way you could do it
i tried everything i could to stop the wipe procedure but it obviously wiped everything
you just backup everything you have got on your internal and external sd card ..
1.Stock Recovery:: Android devices come with Google’s recovery environment, which is often referred to as the “stock recovery.” You can boot to the recovery system by pressing device-specific buttons as your phone or tablet boots or by issuing an adb command that boots your device to recovery mode. The recovery menu provides options to help recover your device — for example, you can reset your device to its factory default state from here. The recovery mode can also be used to flash OTA update files.
2.Custom Recovery::A custom recovery is a third-party recovery environment. Flashing this recovery environment onto your device replaces the default, stock recovery environment with a third-party, customized recovery environment. This is a bit like flashing a custom ROM like CyanogenMod — but, instead of replacing your device’s Android operating system, it replaces the recovery environment.
what you have to do is:
Find the Kitkat official update on the internet accrouding to your [Build number],[model number] [system version] you can get this information in about phone....
If you have asia retail then follow this method http://forum.xda-developers.com/showthread.php?t=2700502
ok Here what i am planning:
1. Uninstall all modules & xposed framework
2. Unroot using supersu
3. Restore/reflash stock recovery (just recovery not whole firmware as I already have stock rom)
4. Install the update either manually via recovery or using auto install.
Am i on right path? Pls help me on step 3, any link or step-t-step guide? I couldn't find one, every post is abt restoring whole firmware.
TIA. Cheers !!

[Q] Flash stock recovery

Hey guys, yesterday I rooted my phone using KingRoot and XZRecovery to flash Super SU and now I want to flash back the stock recovery again because I want install future system updates without problems.
How can I flash it again? (I have my bootloader locked)

There is no accessible stock recovery on Xperia phones, the actual recovery partition will still be there. Dual recovery is installed on the system partition.
If your bootloader is locked you will be able to OTA, but you will lose root. The best thing to do is flash a pre-rooted flashable zip in the dual recovery you have. As soon as there is an update you can make a new pre-rooted flashable zip using PRFCreator.

Restore backup via recovery from sd card?

Hi!
I would like to know if it is possible to restore the 4.4.4 kit kat backup on a 5.1. lollipop system. So basically i would like to update to 5.1 but then I may want to revert back to 4.4.4 with the back up of recovery's 4.4.4 (which is stored on a memory card) Is it possible? Is there a root out for 5.1 yet? please help me if you can.
EDIT:
Here is the solution how to root and install recovery on .368 firmware:
http://techbeasts.com/2015/09/18/ro...ria-z1-compact-android-511-146a0368-firmware/
This is how you create your own FTF firmware with XperiFirm and FlashTool:

This is how you make a pre rooted, flashable zip:

I hope everything is clear now. I followed the steps above and it is working fine.

you can update to 5.1 but use a prerooted firmware with recovery included,don t flash official cause you will not be able to root it and install recovery.
i reverted between kit kat and lollipop many times myself,no prob.
as long as you have a recovery installed i don t thing you will have a problem.
of course make a back up,in case you want back.
now i noticed you post in the wrong section,should be moved in questions and answers

that´s wrong - you can root LP FW with that TOOL from our genius dev @munjeni.
You only had to unlock the bootloader.
Do I need a custom recovery for flashing the new 5.1.1 firmware? I mean do I need the specific XZ Dual Recovery or can I use the recovery which was installed automatically after rooting?

you say that you made a backup of 4.4.4,right?
you entered recovery so you did it either with TWRP or CWM.TWRP and CWM are both recoveries.
you can flash pre rooted firmware and restore backups with both of them,i just prefer better and suggest TWRP.
remember that if you want to restore your back up you need to do it with the same recovery you made it,i think that TWRP cant restore backups made with CWM and vice-versa.
anyway,you can easily find what backup you have if you find the folders named TWRP and CLOCKWORK or CWM in your external or internal storage,back up files is about 4gb size.
how to install now:
1.reboot your phone and when your led light blink press volume down key to enter TWRP recovery.if it gets you in CWM reboot again and when led blink press volume up,so you enter TWRP recovery.
2.now you are in TWRP you press WIPE on the top right box.then drug the slider at the bottom SWIPE TO FACTORY RESET
3.press back button annd shoose install
4.find your prerooted zip,on the top centre under SELECT ZIP TO INSTALL,is STORAGE internal or external sd card
5.install zip:good:
PS:make a fresh backup before you start
Thank you so much. Finally someone explained it normally.
Can someone give me a link where I can find pre rooted 5.1 Rom as a zip file for my Z1 compact? It would also be important to be central europe, unbranded or telekom. Thank you in advance!
You can do one yourself.
I don't have URLs till hands but those are easy to find on forum.
