back to stock based rom - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hello! I have a z3 compact on carbon rom with an ub. Im trying to go back to stock but using my backup or by flashing a stock based rom it never boots. What are the steps i need to take to get back to a stock based rom like "xperience"

If the trouble is flashing through TWRP, you can always try using flashtool with a stock ftf or a modified one that has TWRP and root already.

[Q] Go back to stock ROM from Cyanogenmod/CWM

Hi all
I have CM 10.2 and CWM recovery installed on my Z. Now I'm going to sell it and would like to "revert" to the stock ROM.
I realized that the Flash Tool by Bin4ry and Androxyde only works with stock, locked bootloaders so I cannot install original ROMs the "normal" way.
I assume I need to find a stock ROM image zipped in a format that is compatible with CWM recovery, and flash from there?
Thanks for all help
nope it should work with any Rom just download the ftf you want and flash it it would work with any Sony Device either Locked or Unlocked

question about updating with flash tool

can i flash any stock based rom with root with flashtool? im stuck on stock 4.2.2 and id like to update to kit kat
Well, you can't flash any stock-based ROM with Flashtool. WIth FlashTool you can flash Stock Rom (Official Sony firmwares - .ftf files), but for other custom ROMs based on Stock, you need to have a recovery installed (XZDualRecovery, CWM or similar).
Is your 4.2.2 rom rooted? If yes, you can install a recovery on it (following this thread), and then you can upgrade to KitKat following this thread. After that, you can basically install any custom stock-based KitKat ROM of your choice, from by flashing from recovery.
Goes without saying, read the threads really carefully before doing any actions.
If you're unsure how everything works, you always have a reference in this thread.

Installing Custom Rom

Hi there, i am on stock rom 4.3 and i am considering to flash a custom rom. It is going to be my First flash of a custom rom and i am wondering if something is not working as it should, will i be able to return to stock with no problems? If i install a custom Kernel as well will kies install stock firm as usual (to return to stock)? Or the only method is a full backup and restore? Restoring method restores kernel too? Thank you for your help.
U must rooting your device, next install custom recovery and backup your rom, thats all, and next try the first install omni rom
I am already rooted. Omni is one of my thoughts. Should i flash a custom kernel after omni or it is not mandatory?

Xperia Z not booting anymore

Hi People,
I'm new here and I do have a problem over, as the title says, my Xperia Z (C6603) won't boot up anymore.
Yesterday I unlocked my bootloader, I also rooted my phone and installed Cyanogenmod 12 afterwards using TWRP, this was working perfect and stable.
Today I found out my phone wasn't rooted at all after I installed Cyanogenmod 12. So I wanted to start over again using this way (http://forum.xda-developers.com/xperia-z/general/guide-how-to-root-10-5-1-0-283-t2872873).
So what I've basically done, I installed Xperiaz_10.5.A.0.230_kernel_only.ftf over the CM12 mod, after this my phone doesn't want to boot anymore, getting stuck at the the 'Sony' logo.
Tried to do TWRP -> Factory reset, but it didn't work.
Should I install a full .zip stock rom again instead of the FTF file to restore my old rom?
Kind regards,
xChillz
My root guide and the files provided there are for rooting the 2 stock roms in the thread title only.
You cannot flash a stock kernel onto a custom rom. This is why your device isn't booting.
You can get your device booting in a couple of ways:
1. Extract the boot.img from the Cyanogenmod rom zip and flash it using fastboot. This should allow you to boot into your CM12 rom again.
2. Flash a stock FTF. This will bring your phone back to complete stock. How to package and flash stock roms in FTF format

Thanks for the quick reply!
Could you tell me where I can get a 10.5.A.0.230 stock FTF or can I just Google it?
xChillz.
Thanks bro,
Installed the 10.5.A.0.230 stock FTF, then I installed CM12 and it works!

1.Download the stock rom from letv forum
2.If you r on Codeworkx TWRP, install Chinese TWRP by ycjeson
3.Then install the stock zip file (19s). First time you may get error, flash again the same file.
4.It asks whether to install stock rom, give yes.
5.Now your phone will be with stock rom and recovery. with bootloader locked.

Stock Rom :
https://devs-lab.com/download-letv-official-stock-rom.html#Le_2_Qualcomm_Stock_ROM
rename the downloaded stock rom to update.zip and then place it in the root directory of internal storage
flash stock recovery and click the update option
you'll get an error but try again
That's it!
Better take a twrp back up soon after you flash the stock rom just in case.
