My phone only goes till the At&t sign then just sits there like that. i can only enter download mode and NOT recovery mode. can anyone tell me within detail how to fix this problem? i don't really care if i have to delete everything because i have a backup i made with titanium backup but cant apply it because i cant go to download mode and Odin doesn't flash zip files only tar files. any help would be appreciated.

Lucky enough you can get in download mode. You'll need KK4 (Odin or Heimdall, whichever you're the most comfortable with), from there you'll be able to flash a custom kernel with Odin 1.85 and finaly flash whichever ROM you want.
I suggest you get some reading done before doing anything: http://forum.xda-developers.com/showthread.php?t=1350266
Looking for some help on creating a kernel for stock LT30a. Need to stop the bootloop issue when turning on extended battery mode.
Let me share where im at.
i used flashtool to extract the kernel.sin, this gives me the kernel.elf file.
I then used kernel tools to edit the ramdisk to change settings.
Now i complied the kernel elf. i guessed on this part. as in the dialog it ask's for:
also keep 'RPM.bin' and 'cmdline.txt' in input folder for Xperia 2012 Qualcomm Phones
Click to expand...
Click to collapse
for this i renamed kernel.elf.rpm.bin to rpm.bin and then renamed kernel.elf.bootcmd to cmdline.txt. again not sure if this was the right thing to do. but doing this gave me no errors.
So i have the kernel elf and need to put it back into the kernel sin? i think. Because i see in the kernel update from greg's ftf file, it's kernel.sin (6mb).
This is where i get confused, let me explain.
in the rorgers ftf file is a kernel.sin (20mb) and that's what i used to extract in flashtool to get me the kernel.elf (6mb).
so i guess i need to convert the kernel.elf to kernel.sin and put it back in the ftf file?
I tried to rename kernel.elf to kernel.sin and put that back in the kernel update ftf file but it would not flash.
also the new kernel.sin is only 6mb, it's the same size as the one from greg's kernel ftf file.
If anyone is familiar with the processes i would be very grateful for any assistance.
Thanks

No need for that. If ts correctly formatted as kernel.elf and your compile worked correctly you will able to flash to the kernel.elf via fastboot.
Give it a try.
My stock kernel.sin files are completely stock, so I left them as .sin
However kernel kitchen cannot yet compile .sin kernels for 2012 devices.
Just leave it as .elf and flash it...

Thanks Greg,
I didn't think i could flash in fastboot with a locked bootloader?

you cant.
But you wont be abe to flash any modified kernel anyway, even if its in .sin format.
locked bootloader=stock kernels only (And they have to be signed by sony)
EDIT
If you want a small ftf file for flashing the stock LT30a kernel just make a copy of the stock ftf for LT30a and delete all unnecassary files from it other than kernel.sin and anything needed to flash it...check inside my stock kernel ftf's to see what to leave in.

Hey Greg maybe im missing something else?
Let me explain.
I'm trying to fix the bootloop issue if you turn on extended battery mode with a locked bootloader.
So i have a stock kernel in an ftf file and flashed it to update the kernel. it worked but i lost root.
So i talked with championswimmer and he said i needed to edit the ramdisk and build prop to change ro.secure=1 to ro.secure=0.
so i did that and now i have kernel.elf file.
So what did you do too fix the bootloop issue if extended battery mode is selected?
P.S
i guess the main goal is to have the latest kernel, i also notcied that my manifest.mf file in the ftf file is different than yours.
there's a line that says cmd25: flase and in your ftf file to update the kernel for locked bootloaders says cmd25: true.
Is that something you changed?
Your help is much appreciated.

yes, he probably thought you had an unlocked bootloader. If you edit the kernel in anyway by decompiling it then you cannot recompile it with Sony's signature so you need an unlocked bootloader to flash it.
You need to downgrade to .303, root, install cmw for locked bootloader, flash a stock based .195 .zip then the cmw fix (from the cmw locked bootloader thread)
I think thats the process, but i cant be sure right now, I am pretty drunk as its my birthday today!
Anyway, one things for sure, with a locked bootloader you can only flash completely stock kernels...
PS, i think its this
After you have rooted and installed the cmw for locked bootloaders
•Enter recovery, factory reset and flash the ROM. Then flash the flashable version of CMW recovery for locked bootloaders before you reboot.
Then flash my stock .195 kernel http://d-h.st/ZvP in flashtool in fastboot mode to update to 195 kernel and stop the bootloop
Its all mentioned in my rom thread...

Thanks for the reply, happy birthday.
I have a locked bootloader so no fastboor mode for me.
You can flash completely stock kernels in fastboot with a locked boot loader!
That's the point, I linked a stock kernel that had Sony's signature do you can flash it. It's only modified kernels that need an unlocked bootloader.
If you are unsure about fastboot, use flashtool to flash it, but choose fastboot mode...it will work
Sent from my LT30p xda premium app.
How do I customise the signature on xda premium app?
Make your rom and flash it via CWM, flash the flashable CWM before you reboot (unless you packed it into your rom), flash the reboot fix as well (the one that fixes reboots when editing system files) again unless you packed it into your rom.
Turn the phone off then flash your stock kernel in flashtools. You can use your stock ftf just exlude everything except kernel and uncheck wipe data/cache and stuff. This will reflash the stock kernel but leave everything else alone. This has worked for me with my customized stock .195 and .223.
Hi Guys
My pc can't load ftf files to my z 6603. Could somebody please create a stock. zip kernel for me to flash via TWRP.
Thanks
So I flashed the cm11 ROM for my sony Xperia Z aaaaand, The phone won't turn on at all. Then I realised that I flashed whole .zip package, without extracting boot.img kernel. So I flashed whole thing without kernel and now my phonewon't turn on at all (I know I am idiot). It just showing a red ledlight whereverI am conneting it to charger or PC.
Can u please help me guys? What should I do?
Well, you know the .zip package that you can download from the cm site? There is a boot.img file inside. But insted of extracting it and flash it by the flashtool on the computer, I flashed the whole package (rom + kernel which were inside one .zip file) by cwm on my phone.
[EDIT]
I am trying to repair it by updating the software via Pc companion. I'll let you know if it's worked or not where it will finish downloading update.
@Saguri please download any ROM made for xperia z..pull out the kernel (boot.IMG) connect your phone in fast boot mod(by pressing the volume up key first and then connecting the USB) blue led will light up...now flash the boot.IMG with the help of flashtools ...downland any ftf file for xperia z
..flash it via flash tool but in flash mod and u will get your phone revived back
@Vishalkris thanks, the method with flashtool worked, i downloaded stock rom for my xperia, everything is working now, i am able to use my phone again, thanks.
PROBLEM SOLVED, this thread can be deleted now. Thanks again to everyone for help.
I just replace the systemui.apk in sony z1..can some1 help me to make stock system ui & flash it via cwm...i really need help..my fon was on but blank screen..
Flash any stock ftf file according to your model number through flashtool
I can upload SystemUI.apk
But you have to replace it through twrp because I don't have flashable zip is it ok?
@jebat_durhaka try this flashable zip:
