Hi,
Wondered if someone could be so kind to please upload a Vodafone UK ftf file for either .350 or preferably .434? Been trying to downgrade rooted .253 back to .434 and ended up in boot loop when updating NFC.
Previously took a ftf backup of .434 but boot loops each time when using Flashtool.
Got phone working again by using SUS, and now on on .253 without root. Wish to root again.
I know I could use an unbranded ftf file but prefer to keep Vodafone branding.
Cheers
I want that 2

To stop that bootloop you HAVE to wipe data when downgrading with flashtool.

I have a c6902 in the USA on Tmobile. I used Pc companion to update to stock .290 firmware (Jellybean 4.3), lost root (and thought I was fine without it).
I read a thread about downgrading using FTF on flashtool and that your sim card won't work correctly? (I think that's what i read).
I just wanted to know is this correct or did I misread something?
I'm wanting to revert to the firmware before .290, looking at the FTF thread it looks like .257 is what i need, but Which of the three?
my software id is: C6902 R4B
C6902 14.1.G.2.257 Commercial/Journalist 1277-1348_R1A
C6902 14.1.G.2.257 Generic IN 1277-2364_R5A
C6902 14.1.G.2.257 Generic TH 1276-7160_R4A
Is there anything else I should know or do before downgrading? (aside from making a TA backup?)
I want to downgrade to gain full root again, and the minor annoyances I'm encountering will go away too (mainly sound output issues since upgrading; i.e lost the stock tones i was using for alarms and phone has been rebooted a few times to make notification/ringtones output {stock and custom})
Sorry for my noobishness, (cut my teeth on android using htc phones for the past 3-4 years, this Z1 is slightly foreign to me)
That is correct, you'll lose sim card detection like I did. I used the sony PC Companion to reset my phone (so I got sim detection back), then followed this guide:

Took less than 20 minutes and was so easy.

So you downgraded, used pc companion to repair your problem while on .257, rooted, upgraded then rooted again?
Following that guide, I have a locked bootloader currently. If I unlock it on .290, do I lose any functionality or does the phone just factory reset?

I unlocked it on .290 and I didn't lose any functionality or it didn't factory reset (back up in case) http://techbeasts.com/2013/12/18/how-to-unlock-bootloader-of-sony-xperia-devices-guide/
I used Sony to reset all my phone back to the latest firmware which was .290 (as I lost sim defextion), then just followed the guide I originally posted.I never downgraded.

I tried flashing back to .534 from .290 after I upgraded to 4.3. It kept boot looping then bricked.
Simply, you have 2 solutions to downgrade without losing SIM signal.
1- Downgrade from 290 to 257, then from 257 to 534 (then root then OTA to 257 if you downgraded to root it).
2- When downgrading from 290 to 534, exclude "Baseband" in Flashtool and you'll be good to go.

The only problem I have is I can't find ftf in the ftf thread for my c6902 that matches my id
sent from my rooted Xperia Z1
Dial *#*#7378423#*#* then go to service info then software info and see what is your customization number and look for that number in the ftf thread.
If you want to go back to 257 for root, then you have 2 options:
1- flash 257, then 534, root and OTA to 257.
2- flash 534 and exclude baseband then, root and OTA to 257.

There are numbers before the "R4A", look for the numbers, not the R4A.

Yes, and I'm not sure if the initials in the files stand for the region it is from.
there are three possible files for me to download for the c6902:
IN
TH
journal/commercial
No idea what the differences are.
By the way...unlocking the bootloader did wipe my phone/factory reset it. Oh well I was prepared none the less...
I just realized I didn't reset the usb debugging/dev options, which is why the fastboot isn't working damnit lol...
EDIT----got fastboot working, just can't get the recovery to work. I press up then down, blue light flashes then phone boots to home screen, not recovery.
EDIT---- apparently the key sequence is hold up then press down but keep holding up? can anyone confirm this for me?
Final EDIT-----GOT IT ALL WORKING.... thanks for the help everyone...
Welcome.
I have a C6902 which i updated to .290 firmware from .534. Battery drainage was higher so i downgraded back to .534 using flashtool. My IMEI showed 0's. i flashed .290 again n my IMEI was back, however they were gone again when i flashed .534 again (even excluding baseband as someone suggested in another thread) but to no avain. Kindly help solve this

You have to downgrade first to .257 and than to .534 and your IMEI will be preserved.
For those who have C6903 there is a .534 rom from [NUT] which does not present with the issue: http://nut.xperia-files.com/download.php?dlid=QzY5MDNfMTQuMS5HLjEuNTM0X1tOVVRdLmZ0Zg==
This has been mentioned a few times before, please research more next time
flashed 257 and then 534 and everything's fine now. Thanks a ton mate.
Hello,
I've got new Xperia Z with 10.4.B.0.569 firmware on it. I can't find solution to root device with locked bootloader. I can unlock bootloader then root phone, but first I would like to backup TA partition, but I can't backup this partition because phone must be rooted first! I can't flash custom recovery too because of locked bootloader.
Is any solution for this problem? Thanks for any advice!
If you want to backup your TA partition, you will have to downgrade to 4.2.2 and root.
There is currently no way to root 569 after you have flashed it without unlocking your bootloader.

Thank You for advice. Is there any difference between downgrade firmware and flashing other firmware using flashtool? I mean can I download stock, previous firmware, flash it using flashtool on device with locked bootloader?
Yes, use Flashtool to flash an earlier firmware.
