Flash a Stock Rom - Xperia Z2 Q&A, Help & Troubleshooting

Hi all,
I have problem with my phone again!! I have exintenz rom installed at the moment but need to unroot and flash stock so I can send it back to Sony
unrooting is easy.
flashing a stock rom is not so easy for me... I cant connect to a pc (the fault is with the micro USB not working properly, it connects but doesn't recognize it). so tft and flash tool is a no go.
Is there a way to flash a stock rom from recovery that will get rid of the recovery as well? no root?
I have found prf creator but that is for a rooted stock rom, i just want stock.
I have an OTA notification but it wont install it just says try again after restarting.
Any advice is great, I think I have been clear but please ask me to clarify if i haven't.

From recovery, no atleast without root.

Where can I get the ICS bootloader?

I'm rooted with CF-Root and I flashed the old bootloader to use the USB jig and remove the triangle, but I want to flash the stock kernel (keeping root) so I can resolve the SD issue.
Can I also flash the ICS bootloader via Odin? I can't find it here, but I'd like to get as close to stock as possible, while still keeping root.
Does anyone have the ICS bootloader in an Odin flashable version?
Man here is you need:
Thanks.
Flashed the ICS bootloader and stock kernel, then reflashed the CF-Root kernel, per Chainfire's advice, now SD works (yay!) and I have root with no yellow triangle.

Just tried that and still not working.
I don't know if you can use the USB jig with ICS. I had to backup my rom, factory wipe and reinstall a stock gingerbread rom. This rom turned out to have the new bootloader which also doesn't support a USB jig, so I then had to flash the old gingerbread bootloader, insert the USB jig and it wiped the data. Then I reinstalled stock ICS, rooted using Rachmat's Simple ICS root method and then restored my rom backup. Bit of a long winded process but every time I flash a new rom now, I don't get any increase in the counter.

[Q] Help think phone is bricked

I recently rooted the phone and wanted to install a custom rom. When I tried to back up the current stock rooted rom with rom manager, someone went wrong. So I was then stuck on a flashing black screen. But I can still access Odin/download mode. But whenever I try to flash something, it flashes, but the screen just reboots back to the flashing black screen. Help please I dont know what to do
What firmware base did you start from, and what method did you use to root the phone?
Rom Manager is not recommended for use on the I777 phone. You need a custom kernel which contains ClockworkMod Recovery to back up the phone. Did you try to install ClockworkMod Recovery from Rom Manager?
Need more information before we can help. So, answer the above, and provide as much detail in addition as you can.
I almost messed my phone up by not rooting or flashing a ROM the proper (safe) way and ended up using a return to stock / unroot guide to start fresh and just follow the guides for rooting and installing ROMs from there.

I want to go back for ICS

Hi, I just flashed UK Retail firmware from here ( http://forum.xda-developers.com/showthread.php?t=2231289 ) and I wanna go back to nonEIFGS Retail. How can i do that ? When I'm trying to flash an old firmware RSD fails and the phone remains in Fastboot.
It's impossible due to locked bootloader.
If there is no way back, can someone leave a tutorial on how to flash CM10.1 ? And if I flash CM10.1 it would be the only ROM in my phone or I need to keep the Stock too ?
PS: Forgive me but on my old phone things were simplier.
First of all - is your phone rooted? I assume it's not. So the first thing to do if you want CM 10.1 is rooting your phone. Then you should install boot menu manager or safe strap recovery. And with one of these tools you'll be able to flash cm or any other rom. It depends on you whether you want to keep your stock rom or just back it up and delete it.
Yes, my phone is rooted and I tried with BMM but when I booted with the custom rom nothing happend and the red let turned on.

Don't let it auto reboot after the recovery flashes. Either uncheck auto reboot or just hit the combo for recovery when the phone reboots. Many newer Samsung phones have a script that reinstalls the original recovery if it realizes that you have changed it. You have to install another rom or root it and remove the script and reflash the recovery and it'll stick if you just want stock rooted.

didn't worked...... after i flash the recovery (i'm in download mode) i boot directly into recovery.... the same problem
try to instal the recovery via rom manager.....seems to work.....but when i want to boot from rom manager into recovery it show me an error ("an error occurred while attempting to run privileged commands !" )
what should i do now ?
http://galaxyyoungs6312.blogspot.com/2014/01/clockworkmod-recovery-for-galaxy-young.html
6310 + 6312 use the same recovery.
yeah....but i tried that rooting method and it didn't work....
maybe i can flash a new rom from ADB but i can't pass the signature verification
any ideas ?
Well I can tell from your pictures that you didn't follow the suggestion of trying SuperSU, but that might not help anyway. That Framaroot version is an older one. Get the updated version from here: http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276 and use SuperSU instead of Superuser. Sometimes you have to run it a couple times before it'll go through. Reboot in between tries. Here are better instructions for the rest of the process:
http://forum.xda-developers.com/showthread.php?t=2460029
man ...didn;t work... ... tried at least 5 times .....
or....i can flash a rom from ADB but i can't pass the signature verification....
a have an ideea ....maybe i can flash via odin a rom whit a custom recovery ...from there i can flash an old backup of mine .....it's good to proceed right that ?

I don't understand what is the problem but you can always use flashtool to flash stock firmware.

The problem is that whenever I try to update twrp to 3.02 the device dies and does not turn on or in recovery mode it enters, with that I can not install any Custom Rom.
I install Stock rom 5.1.1 which I found, then I do Root, then I install Twrp 2.8.7, but when I install 3.0.2 the device dies ..
Why you don't install stock 6.0.1 with flashtool .
