Back to stock

Hello I have an xperia z c6602 I'm currently using pac man rom with meow kernel
My bootloader is unlocked and I want to go back to stock
I have a CWM backup of my stock rom. And a backup of my TA partition (i read it was useful)
How do I go back to stock? Can I just restore my CWM backup? Or I have to flash through Emma? How do I restore my ta backup?
Can someone be so kind to guide in a newbie way please? (I'm use to play around with Samsung devices. This is really different!)

Hello, I was on pac rom few days ago as well, then i decided to try miui which is based on stock.
So here's the steps:
BACK UP ALL YOUR INTERNAL SD FILES AND FOLDERS because flashing ftf will erase everything inside internal sd, I never did a backup, lost all the chats and messages. :crying: :crying: :crying: :crying: :crying:
copy all the flashable .zip u want to your sd card.
Flash a stock .ftf file .67 / .74 will do, then root it with any method u want
then flash original kernel using flashtool
then reboot str8 to recovery and proceed to do a clean wipe then flash any stock custom rom you want.
let me know if you have any doubts or question here.

My method is
1.Backup everything, photos, messages, app data using titanium backup, literally everything you need.
2.Store backups somewhere safe, especially titanium backup file(the whole thing).
3.Flash back stock rom and wiping everything.
4.Relock bootloader.
5.Now you have a clean phone, root it again and restore titanium backup app datas,
But be sure to only restore games, apps, but not system files, it may causes crash.
6.Restore the rest of them.

Thanks for the replies! Do you know how to restore my ta backup? Or by flashing the stock rom it would be the same? If not. At what part of the process should I do it?

restore ta backup is the last step basically, ( after flashing stock kernel and stock rom)
i think you used the backup ta for windows from one thread if i'm not wrong,
just restore dry run just to make sure the ta is correct and then just restore it
(the phone should be power on like normal, with usb debugging on)
for your concern, cwm backup also can be used, just restore it and it's done, but, the app data and all other things will return to the state during the time you made the backup, so the progress you did in this custom rom wil not be saved, unless you used titanium backup after you restore nandroid.

Excellent! Thanks man I will restore my backup and restore TA. And yes. I used a Windows tool to make the ta backup (don't even know what's that for. I just read it was important) haha

1. Your stock rom, and it's data
2. You can flash another rom. But, if you are going to restore your backups. It will be do nothing, because your phones going back to previous rom, data. Do a normal flash rom, and then you can do a backup, if you want.

That could be the problem. I also tried once 4.3 >> 4.1.2 without wiping data, resulted in bootloop as yours. (But going from .266 to .201 without wiping data worked). You might have to flash with the three check-boxes ticked (wipe data, cache and appslog).

But the only reason to downgrade is to backup data using cwm recovery and then root 4.3
By wiping ill lose all my data i.e. drm keys.

That's the dilemma I also faced Had to start all over again.. You can try "Backup&Restore" app that comes with stock rom. But that didn't work for properly for me
Btw, can backup sms, contacts, etc and app apk's with 'SuperBackup' app. But it won't backup the app data.
Because your BL is locked, have to downgrade to get root and a recovery. If you unlock the BL now, that itself will wipe the data! No way out I think..
Can u think of an alternative?
**Edit - wiping data won't erase drm keys. Unlocking BL will erase it. Before unlocking, you have to backup TA partition to save the drm keys. For that we need root! Again back to the same place.. oh.

I have to ask something.What will happen if :
I wipe my all data,cache and the third one,will it install 4.1.2,
If it does,i can root 4.1.2 using @DooMLoRD easy rooting toolkit,install cwm and take backup.
Then flash 4.3,root it and restore backup from cwm.
Will it work?

All you can do: Reflash 4.3 without wiping data etc..
Make a backup with the backup app from sony (backup to external SD)
Flash 4.1.2 and wipe everything.....
Boot up and restore backup..

am on unlocked bootloader. no problem ryt??

dosent matter mate.

I bought this phone, backed up ta partition, unlocked bootloader, installed cm11, then iHachers ROM 4.1 (with dual recovery - CWM and TWRP). How can I return to stock, lock the bootloader and restore ta partition? (make it like it was when I bought it)
When I backed up the the ta partition, I accidently deleted it, so i recovered the deleted file with Recuva. I only managed to recover a ZIP called TA-backup-20140717... .zip, which has 6 files in it. Is this the only file needed to restore ta partition and (it is 188 KB) is it corrupt ?
I know I should use Flashtool, but I do not know which FTF to select. If I restore the phone with Sony PC Companion, will the device get bricked? Because it is rooted with custom recovery and unlocked BL.
Thanks :good:

Pc companion will not even start to update your phone since it its rooted and bl uncloked.
Anyway, you need to flash FTF for your device (ex. C6903), best is Generic World latest one.
After that restore backup of TA

Thanks for the quick responce :laugh:
Is it possible to upgrade from iHackers 4.1 (Stock 4.4.2) with custom kernel, recovery and root, by only flashing the kernel and recovery FTF, restoring the TA (so that the BL locks again) and then upgrading over the air (OTA update) ? I know I will lose root, but are my data going to be deleted by upgrading from 4.4.2 to 4.4.4? I have the C6903 version.
Also, if I flash an ftf that includes everyhting (system, recovery, kernel,... ) and deletes all the data (so the phone will become like new), and choose a wrong generic ftf in this list ( http://storagecow.eu/index.php?dir=Xda/Sony/Xperia+Z1/C6903/Generic/14.4.A.0.108/ ), will I brick my phone?
I have never used flash tool (i have not even downloaded/installed it!) and i am afraid i will brick my z1...

I didnt understand first one, so i will not answer to this, i dont want make any confusion.
Yes, if you flash everything your phone will become like new, and if you flash wrong "ftf" worst case scenario is that you will need to download new FTF and flash it again with correct one.

[Q] Few questions about unlocking bootloaders

I'm really sorry if these questions have been posted before but I couldn't find them anywhere. I am rooted on an Xperia Z1 C6902 with a locked bootloader. I have read that unlocking bootloader wipes your phone as well as sd card. So, here are my questions:-
1)I made a TA backup as suggested but I want to know what it will do when I restore it, will it be like a factory reset or will I retain my apps, or something else?
2)I backed up my apps using free version of titanium backup and I've read that it stores the backup on sd card. So after unlocking bootloader, won't these backups be deleted as well?
3)Is there a way to transfer said titanium backup backups to my computer for easy restoration later?
4)I've also read that restoring titanium backup while on a different rom will cause problems. Does this mean I have to start over if I get an AOSP ROM or Cyanogenmod(I really want one of these)?
5)Can I just take the sd card out of the phone while unlocking bootloader so that it's not wiped? Then restore apps from titanium backup?
6)Will unlocking bootloader using flashtool install a custom recovery as well?
I understand these are noob questions but please help me out I'm really confused
Please answer with the corresponding question number please
Sorry for too many demands/questions

Yep,BL unlocking does erase all your data!
1)when you restore the TA backup,your bootloader status goes back to locked,it will be like you never even touched the bootloader.But,the device wont boot up if you still have a custom kernel installed,so you have to flash back the stock kernel
2)I dont know about titanium backup
A better alternative is: Install XZDualRecovery(on locked bootloader) and make make a backup using your recovery of choice of /data(which contains all the apps/configurations/saved passwords blah...blah)onto the /sdcard.
Then unlock the bootloader and then restore the /data backup after.so everything including your apps and settings will be restored
5) as far as i know ,the sd card WON'T be wiped but you might as well take it out just to be safe
6)No,unlocking using flashtool will not install a recovery,the recovery is stored on the kernel(or not , if you flash a recovery image to the FOTAKernel Partition).

1) the TA backup returns the DRM keys to your default ( what you backed up) which means makes your phone untouched like its first day ( only about bootloader status,kernel,some DRMs like xreality and ... )
_____________________
2)the titanium backup , saves the backups in the folder TitaniumBackup placed in sdcard(internal storage). you can copy the entire folder in your pc or external storage to save it from deleting and put it back whenever you need it
sdcard/TitaniumBackup
_____________________
3) as i said in 2 yes. you can save the folder everywhere you want and replace it whenever you need your backups( u can also save just one or some of your backups if you want by saving the files in the folder)
_____________________
4)it depends on the app you are about to restore.. most of third party apps will not have any problem.even from device to device.. but the story is totally different for system apps
_____________________
5)yes you can do that..
_____________________
6)as i know,no.. it depends on your custom kernel...just flash a custom kernel and you will have the recovery:laugh:
and my friend! unlocking the bootloader it self, will not erase any of your data !! none of those! its a procedure that makes your phone able to accept and operate from a custem kernel instead of pre-installed kernel.. but if you change your ROM or flash a new ftf file(official roms from sony) , your internal and your personal data such as appdata,contact & ... will be erased . and you can select whether wipe the internal or not!(thats depends on your choice) and your ex-sdcard will be safe unless you select to format it!
and be very careful and good luck

Haha well I decided to go ahead and do it anyway
I got the apps and data back so nothing bad happened. I want to know how I can get clockworkmod on my device.
Android ROM manager says no official version of clockworkmod is supported for xperia z1. But then in a menu it also lists TWRP and clockworkmod as already installed on the system and asks if ROM manager can use those for its purposes. So that's why I asked if flashtool installs custom recovery as well.
Whenever I try to boot into recovery to make a backup, it boots normally instead. I hold down the volume up/down buttons and press them quickly on boot, the phone vibrates multiple times but no recovery mode, which leads me to believe there is no custom recovery installed, but ROM manager refuses to download clockworkmod and says there are two installed already! Neither of which can be accessed(if they even are on the system).
Sorry for this convoluted message
Any more help is greatly appreciated

To get a recovery on your phone,You have to A) Flash A Kernel using fastboot commands or B) Install XZDualRecovery
Since you have already unlocked your BL,flashing a new kernel would be the best option as it give you tons of new features like DoubleTap2Wake and Overclocking(or underclocking!!).Check out the android developement section for kernels and roms!

All the kernels for the Stock Sony Roms for the z1 come with a recovery bundled in it(just basic cwm,not fun at all).I think some CM/AOSP based kernels lack recoveries(but i dont know for sure)!!
See,other phones have separate stock recoveries on dedicated partitions(only for software updates,no custom ****) and you can flash a custom recovery into that recovery partition and load it up.But sony....oh no...sony doesnt load a usable true-ish-recovery into its phones nor do xperias have a real partition for the recovery...so we have to get by with these tricks.....
Well the best you can do is you can install a custom kernel and then flash a recovery to the FOTAKernel partition.then the kernel will the load the recovery from the fotakernel instead.
