[Q] Any precautions before downgrading from .290?

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.

On a C6906, I had no issues whatsoever downgrading from 290 to 257.

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.

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...

[Q] C6906 - Flashing .290 branded to .290 generic

Hello,
I recently bricked my Z1 and just got it back from warranty repaired. It is a C6906 that they upgraded to 4.3 (.290) however it is branded to BELL and I wish to flash the unbranded generic so I don't have as much bloatware/fast updates.
Since I do not wish to brick the device again and go through this again and so I am looking for advice to do this in a way that is guaranteed. With flashtool if I flash "C6906 14.2.A.0.290 Generic CA 1276-7484_R2B" would I have any issues at all? Just load up Flashtool - select the ftf and just use the default settings and plug in the Z1 while holding down the volume button.

I used the latest Flashtool v0.9.13, connected to PC, let install windows the drivers, selected the Unbranded Stock ftf, wiped all data, appslog, cache, all the rest unchecked and I performed the flash. All fine and the phone working well. I don't know why you had problems or why you bricked the phone but there is no advice to give you because it's simply. So even if all it's clear no guarantee and it's up to you. I don't think is the FTF faulty.

This is separate from how I bricked it (using custom rom), I did this previously with a older version and just not on .290 and I am wondering if there is any issues (IMEI etc) doing it .290 to .290, thats all. I just don't want to make a mistake.

Ok, so you bricked the phone with custon rom, now I understand. In this case there is no any issues flashing .290 unbranded on .290 branded. IMEI is lost only when jumping .257 and downgrade directly to .534. It's more "safe" flash .290 on .290. Go flash now.

Thanks. I don't suppose there is any working root for 4.3 yet, is there for the C9606?

No direct root, like Vroot or 360, for .290 at the moment, just a method to get full root for Locked Bootladers. To do that you have to downgrade, root, install recovery then update to .290 again, a bit longer to get root on your phone, sure this method working for C6902/3 but should work for C6906 too, just check.

Would I be able to go from 290 branded to the new 136 intended without issue? I already bricked one device trying to root and I'm just trying to make sure lol

Probably because when you bricked your phone was the time when some issues was not discovered yet in do that, and this confirm the fact on the thread now is wrote "How not brick your phone" . BTW, the risk to brick the phone is in downgrading so if you want just to upgrade without Root this way should be more "safe" and you will be able to do it without any issue.

[Q] Unable to downgrade to .534 after mainboard change!

I have rooted my Z1 many times without problem, first downgraded to .534, root with Bin4ry's root tool, then flash the .zip file from recovery and flash stripped .ftf with FlashTool.
By rooting this way I can keep my bootloader locked.
A couple of weeks ago I had to send my phone for repairs when the call speaker gave up and they changed the mainboard (new IMEI).
After this I can not downgrade to .534 anymore! It will stuck at a bootloop, with only the Sony logo showing. Downgrading to .257 (the version after .534) is no problem though.
I have tried many different .534 tft-files, including NUT's.
Any ideas? Could this new mainboard be incompatible with the oldest firmwares? Sounds unlikely to me.
Thanks!

If it's incompatible with 534 then i'd be surprised, my guess is that it's a dodgy download and you should re-download the FTF file or an alternative and make sure it's the only thing that your computer is doing at the time, even check the MD5 checksum if it's available.
Are you flashing the full FTF file when downgrading and allowing for a wipe?
Only problem i've had when downgrading is losing the IMEI but after you've rooted , installed a custom recovery and installed a custom rom that'll come back anyway.

Thanks, yes I have tried with 5 different .534 ftf-files, all of them resulting in this bootloop. I am doing a full flash with wipe. Downgrading to .257 is working fine though, but then I cant root.

It's not branded. No SIM-lock, Generic_NCB customization. C6903.
Now I have tried with older versions of FlashTool and I tried other USB-ports too, but no success. Newer firmwares then .534 flashes just fine.

Which version of flashtool are you using currently? I've found that some firmwares just don't like the older flashtools.
What about different USB cables? Shouldn't make any difference but I thought I'd ask. I find it odd the way it'll work for newer but not older firmwares, perhaps someone else should chime in with an idea.
I'm all out, as this isn't something i've come across and everything i'd try myself i've told you.

Now I have tried with another computer and another USB-cable, and also tried to flash the older .526 and .518 firmwares. Tried FlashTool 0.9.1.6 and .5 and .4.
Same result.
Seems very strange that this new mainboard should not be compatible with these firmwares?

It send your IMEI number to an IP address in china..

Well, I tried vroot because it is in the first posts in the "Ultimate Xperia Z1 Guide" sticky thread.
Since I have always used Bin4ry's tool, I guess I have not noticed any thread about vroot being dangerous.

Right now I have .257 firmware flashed which is a 4.2.2.
I have tried to root with Bin4ry, vroot, Kingo, and [NUT]s recovery, but it is not possible.
Everywhere I look people say that it is a must to downgrade to .534 when rooting with a locked bootloader.
What have I missed?
Thanks,

257 was the first one that closed that exploit, you have to go back further.
I know you say 534 does not flash for you, but what error does flashtool give?

No error in Flashtool, flashes fine but is stuck on bootloop with Sony logo.
Tried .518, .526 and .534

make sure you do not exclude any part of the FTF and wipe everything,
Can you get a log from the phone?
Make sure you backup and clean your sdcard (So there is no trace of recovery files on there)

I have cleaned the internal sdcard and tried without external sdcard and simcard.
Don't think it is possible to get a log file from the phone while in bootloop?
If my new mainboard is incompatible with .534 and older, I guess other users would have the same problem?

[Q] How do i get from vanilla to Xposed?

Hi everyone,
So i have an xperia z1 on 14.3.A.0.757. Vanilla, not rooted, havnt unlocked bootloader.
I would love to get Xposed Framework but i have been searching all over the interwebs but its so unclear.
Could someone explain to me EXACTLY what needs to be done to get from vanilla to xposed? And how i would go about doing this, the easiest way! Any links to good explanations and step by step guides which are safe would be much appreciated!
Thanks,
Marcel

Is there any way to root the phone without it being wiped?

Not from a 757 firmware.
You can try excluding data when using flashtool, but I wouldn't do that.
However, if you can update to 4.4.4 via pccompanion you will not lose data and you can root that very easily without losing data using newroot

Yes there is, what build number are you on, you said 757, but that's not 4.4.4
Please post what it says in the build number and android version from settings/about phone

4.4.2 (woops thought i was on 4.4.4....)
14.3.A.0.757

OK, you will probably lose data when rooting then.
Flash a FTF from the FTF mega collection that ends in .108 or .118
then use the newroot tool to root it

Either downgrade to android 4.2 (i.e a firmware ending in .534) or upgrade to the latest android version 4.4.4 (ending in .108 or .118) and root it.

Need c6606 .283 firmware

hi guys,
im in need of the .ftf for my c6606. i have searched everywhere and cant find a damn thing for the 10.5.a.1.283 firmware. before my phone officially got the update for KK i decided to flash the customized firmware and it changed my phone to c6616. when trying to restore my phone it says that there is no firmware to download in pc companion. the reason i want to start fresh is my phone has issues with mobile data sometimes and even on wifi, data just wont load.
thanks guys

Follow part 2 of my guide to package your own FTF using Flashtool. Just make sure your installed version of Flashtool is up to date.
Once you've done it, you can share it in the general section to help others looking for it.

Thanks for the reply. I want to flash the baseband that is for the c6606. By doing it that way would there be any issues? Or should I just root the phone and change things in the build prop so that it says it's a c6606 and hopefully it will update that way

Just try what he said,i did that yesterday and all went well,just see if you do it right!

So after trying a few firmwares I had issues with phone kept restarting. So I wiped everything and flashed back to the available c6606 firmware and got ota for 4.3 after that. Now that I'm on 4.3 it says I'm on the most up to date fw in PC companion and on phone. Sony website says most up to date is the .283 KitKat fw. Any reason why I can't update?
