Xperia Z3 Dual (D6633): How do you backup the stock boot.img? - Xperia Z3 Q&A, Help & Troubleshooting

Hey everyone,
I'm planning on getting Magisk for my Xperia Z3 Dual. Now before I start doing literally anything, I want to ensure that if I screw up, I can flash the original boot.img back onto my device.
But right now that's my problem.
I can't seem to find a way to get the stock boot.img.
I've been looking around the web for a while now and everything I found required either a custom recovery, like TWRP or an already rooted device. As for the custom recovery, I'd be all for it, but I read that TWRP is only available unofficially for the Z3 Dual and requires a custom rom.
Is it possible to backup and get a boot.img from my device without literally changing the entire system already?

Urgent help - Is possible to do this?

Since my AT&T ICS 4.04(final update) Atrix 2 won't pass beyond the M logo (have been flashed like ten times), I need someones help.
I can't downgrade to GB because would brick the phone forever or upgrade to a newer version. Or flash a custom ROM because the phone is not rooted and doesn't have any custom recovery tool installed.
So, I was thinking, maybe if I could flash an already rooted system and a custom recovery using RSDLite, could boot into the custom recovery, install a custom ROM and see if I can fix my phone.
Or maybe flash(RSDLite) a backup(or only the files need for this purpose) made by any user of the forum.
Is that possible? Please help.

It would be better to ask all the questions in one thread itself, rather than making new ones each time for a newer question.
RSDLite can't flash files which aren't signed by Motorola, hence no pre-rooted or custom recovery installed ROM can be flashed this way, since they won't have Motorola signatures.

[Q] How to backup stock recovery?

Hi,
I want to root my Mate7 but I am not comfortable with messing with recovery. What is the way to backup stock recovery so I can put it back with fastboot flash recovery after rooting is done?
Thanks.
Hi xtonda - the package going around for unlocking/rooting the Mate7 currently that contains the recovery_b60.img also contains a copy of the stock recovery.
If you follow any of the guides available (off hand I can remember http://mate7.net/ascend-mate7-bootloader-unlock/ from the other day, but plenty guides available on XDA and elsewhere) the tools/driver package includes the stock recovery.
Flashing the stock is done in exactly the same way as flashing the CWM, just with the different file.
So you'd unlock, flash CWM, root the device, then flash the stock recovery again
Cheers - hope that helps!
Hi, I found two guides to root Mate7 here and each has own package with CWM recovery and some original recovery. However these original recoveries are not the same so I am not convinced that they are exactly the same as the one in my device (obviously at least one of them is not) since there are several Mate7 variants and ROM version and is unknown where these "original" recovery images come from. That is why I want to download original recovery from my device and flash it back after rooting.
Or to boot CWM recovery only temporarily without flashing it, I found that it should be possible using "fastboot boot" command. Is that possible?

Easiest way to reinstall stock rom

Hi all as title states my moto g is downloading the new 5.0 update but during install it says error and switches phone back on with no changes made. It was rooted and custom firmware was installed. Since then uts back to fully unrooted, stock recovery is reinstalled and bootloader is still unlocked. However still it errors a quarter into installing.
So i have come to the assumption that it is best for me to revert/ reinstall the stock 4.4.4 rom back on and try updating after that. However seen loads of complicated methods on how to reinstall the stock firmware onto my phone so want the easiest way if possible.
In attatchments is the info from the current stock rom that is on the phone (will state a custom rom has never been installed to the phone always been stock) and i have downloaded the following to put onto it:
XT1032_RETAIL-GB_4.4.4_KXB21.14-L1.40_36_cid7_CFC_1FF.xml.zip
Ive tried using the mototools v3.1 and does abserlitly nothing non of the commants work or do anything with my phone.
So which is the easiest method?
Many Thanks
major problems!!!!!
Stock recovery installed to phone. Started update it was installing and got to 3/4 of the way through, errored, restarted and not goes in a loop saying no command!
Phone will not switch on!!!
Why has this happened?
If fastboot is too convoluted - using a custom recovery, flash one of these zips:

What update were you installing when it errored?

Trouble installing CWM/TWRP on ROOTED & UNLOCKED Xperia L with Stock FTF

So, I have a ROOTED & UNLOCKED Xperia L which creates problems while installing a Custom Recovery. At first I tried the TWRP 2.8.7.0 which just wouldn't boot the phone and after using the Flashtool to reflash the Stock FTF; I tried the Rashr app and Minimal ADB and FastBoot to flash Recovery as well.
In every case the phone either wouldn't boot or just stay with TeamWin Logo Flashing intermittently.
I wonder what nooby mistakes are letting this kind of thing happen.
Long Story short - I need a decent custom recovery image (download link) that works on a Stock Xperia L that helps me take a full backup and the steps to install so I don't end up using the Flashtool everytime.

Xperia E3 (D2243) won't root?

I followed Vinay's steps for root and recovery on a Sony Xperia E3, however after the root fix reboot SuperSU isn't installed and obviously I can't access any root only functionality. The phone is on KitKat (4.4.4/18.5.0.25), stock rom. I believe the stock rom may be blocking it (although I could be wrong since recovery should have priority over it) and the only thing stopping me from installing a custom rom is the lack of DTV support, because the phone belongs to a relative. The reason for rooting is because his phone is too bloated, updating all apps and installing a few more just use all storage.
