[HOW-TO] Unbrick your XZU - Sony Xperia Z Ultra

If your XZU freezes / restarts while booting, it's probably soft-bricked (in fact it's almost impossible to hard-brick it). Use this guide for a clean restore:
- internal data will be wiped
- no root required
- no unlocked bootloader required
- Windows is required
Download Flashtool: link to krabappel2548's post
Install Flashtool
Install drivers using the Flashtool-drivers.exe which is located inside the "driver"-folder of the installation path of Flashtool. Include the flashmode, the fastboot and the XZU drivers.
Download or build a full stocked FTF firmware file fitting your model. Choose Method A (fast) or B (recommended):
Method A (fast): Download a complete FTF-file from the XDA forum (for example link for C6833 or link for C6802 or search the forum for a up to date firmware fitting your model). Move the FTF-file to the "firmwares"-folder of the installation path of Flashtool.
- or -
Method B (recommended): Build your own .FTF file with the newest official stocked firmware:
Install Sony PC Companion: link
Do not connect your smartphone to your pc. Start Sony PC Companion, choose "Support Zone", start the software update. Click on repair and accept everything on the following dialogues. Sony PC Companion will start downloadng the newest firmware.
When the download is finished, exit Sony PC Companion. Use the search function of windows to locate a folder named "blob_fs". This is the place where Sony PC Companion dumped the downloaded firmware. You need 4 files named "FILE_XXXXXXXXX", which have different numbers and no filename extension. There are two small files < 1 mb, one medium sized (circa 20 mb) and one big file ( > 700 mb). Ignore the ICON_ files.
Start flashtool.
Choose Tools > SEUS Decrypt. Choose the "blob_fs" folder as source. Convert the 4 files. Wait until the Bundler dialogue pops up. Content everything you just decrypted and fill in the three fields (Device, Branding and Version). Click on "Create". Wait until it's finished. You will find your fresh FTF file in the "firmwares"-folder of the installation path of Flashtool. Leave the file where it is.
Now it's time to flash the FTF on your XZU. Start flashtool if you haven't yet.
Turn off your XZU and wait at least 5 seconds. If you cannot turn off your XZU, hold the power- and volume-up-button at the same time for 3 seconds. Your XZU will vibrate briefly and poweroff. Or push the button inside the Micro SIM card slot: link to Kiwi Tech video. If you choose the last method, don't forget to leave a youtube comment on Kiwi Tech's video declaring war on his overlong intro
Plug in a fitting USB cabel to a USB 2.0 port of your PC. Do not use a USB 3.0 port. Enter Flashmode: Hold down the volume-down-button and connect your XZU to the prepared USB cabel. You can release the button when the LED lights up.
Flashtool will notice your XZU in flashmode (check log). If not, reinstall the drivers using Flashtool-drivers.exe. Inside flashtool, click on the lighting symbol. Choose Flashmode.
Choose a full FTF firmware & click on "Flash". Wait until it's finished.
Your XZU is now unbricked. Have fun

I got my Z1 Ultra today, unlocked bootloader and tried to get root following "[HOW-TO] ROOT 14.1.B.2.257 and poosibly newer Sony Roms"
I screwed it up and the phone boot looped. I now realize flashtool was at fault refusing flashing stuff. I reinstalled it lots and then installed it one more time with version .12
I tried flashing and now it finally flashes the newest firmware!
I guess my phone will be okey now .
--
Yep, phone works.
Thanks for this thread.

If I go with method B how I know that it will download the latest firmware for XZU not for any other sony phone.

After decrypting you will get a elabel .sin-file, which includes information about the firmware version (for example "elabel-C6833-row_201310161732.1_14.1.B.2.257_XXX"). During the repairing process of the Sony Pc Companion a screen will pop up and asks you to choose your smartphone modell. But at that point your download is already finished, which is quiet confusing too me. For me it worked perfectly and the built FTF file got the estimated file size (circa 780 mb). Maybe someone can test method B to the point where you decrypt the files and tell me if he got the fitting elabel.sin?

[Q] New member new phone (Now a big problem as well)

Hi, everyone I just joined this forum. I have X10i with firmware 2.1. While searching the thread i came acrosss terms like root, xrecovery, flashing, MT, generic etc. Can someone help me out what these terms mean. I wanted to upgrade my phone to gingerbread. Previously I am an iphone user So i am total noob to this OS and the phone
Thanks in advance
good get away from iphone
root--same thing as jailbreak
xrecovery-- a badass tool that lets you flash roms onto your phone.
flashing-- umm... it is like installing a modified version of even the legit version on the device
generic-- A product having no brand name or registered trademark
example= for device there is branded or non branded
branded means that a company like ATT or Rogers approves that firmware or OS version. So when you turn your phone on, you will usually see something related to them. like an animation of the att world
generic--- clean install. no company restrictions. just regular
ok links for all that crap above
2.3.3 firmware (does not matter if you download x10a or x10i)
Generic-----

I tried that too and amazingly the flashing goes all the way to the end on 0.2.5 in the end i get the msg that flashing complete and remove the phone but when i remove the phone and turn it on it just vibrates and small blip of green flash led than nothing
What could be the problem
1. Download Flashtool from
http://doomlord.sylvester20007.com/x10/x10_gb/FlashTool_0.2.9.1-GBready_root_xRec.exe
2. Download the generic 2.3 ROM of your choice
http://forum.xda-developers.com/showpost.php?p=11038646&postcount=1
Personally I would get the Global version unless you can find your country specific one.
Global version download - http://www.multiupload.com/JEXUAHAZTL
3.
a) connect your phone to your PC, make sure it installs the drivers (if your Sony software is working it is fine)
b) Extract Flashtool into a directory you know
c) Extract the firmware file you downloaded. And move the ftf file into the "firmware" directory of Flashtool
d) Make sure your phone is not connected to the PC and is off.
e) Run Flashtool, click on Flash and select the firmware you have just downloaded.
f) It will give you the same instruction - holding the "back" key, (phone still off) connect it to the PC. If you did this correctly, the light will be green and it will start flashing your phone.
g) After it is completed, reboot your phone once or twice and check that it is working.
4. Installing xrecovery and rooting refer to instructions (you already have all the files from when you download in step 1)
http://forum.xda-developers.com/showthread.php?t=1196808
Let me know when you have completed the steps above.
Thanks for advice downloading it now and going to try and will let now about the results

I have flash tool 0.2.5,0.2.8,0.2.9,0.3.0
Have tried them all only 0.2.5 goes all the way to the end but when i turn on the phone it only virbrates and green led flashes for sec than nothing
When you reboot is there anything showing on the screen? Sony logo...anything? If yes, wait it can take a long time for a new rom to install. If no, I think you need to revert back to the 2.1 rom, root and install busybox, superuser, and xrecovery. once thats done you can backup your rom and data so you don't get stuck updating or if you have trouble with a custom rom etc. Also I think your battery stats should be wiped using xrecovery, it sounds like SEUS checked this and the file said your battery was too low to continue the update. Here is a good place to start.

Try taking the battery out and then try flashing again. Which ftf file are you flashing or selecting in the flash program. You need to use at least a 0.2.9 version of the flashtool.... if you use 0.2.5 start with the 2.1.54 ROM first.

[Q] X10 mini doen't start anymore and SEUS unable to restore stock kernel

Hello,
i tried to put minicm9 on my x10 mini. It has work but sim card is not detected.
After that, i made a big fault
I used s1tools to relock my phone (by restore button) in order to see if my sim card becomes detected
Now, my phone doesn't start (led blinks one time and vibrator and no more)
I tried to use SEUS to restore stock kernel but it says i have the latest release and no button to force
With flashtool, i can't flash another kernel because my bootloader is now relocked and i have nothing in pluging menu
Any ideas of what i can do to have my phone starting ?
Thanks and regards

Hello,
i have already try this but SEUS indicates that i have the latest version of software and no other possibilities offer by SEUS except "exit" button
i got a.ftf file of generic 2.1-update1 that you can flash with flashtool if you want

Disconnect your phone from your computer
in PC Companion, go into "support zone" choose update
It will say: phone not found and give you the repair option

If you disconnect your phone from your computer, it can't say you have the latest verstion because it cannot find it and it will give you the repair option.
Once you click that, it won't check for phonetype or software anymore, it will let you select a model, download the firmware and flash it.

After select my model, at step 3 (update) when i plug my phone, a window opens with "no software available for your phone, try later" (in french with my se pc companion but i translate, well i hope)
very well translated indeed no problems there
just strange that it can't find a firmware for your selected device, does PC Companion connect to the internet? top right corner of main screen (PC Companion settings), proxy settings, test...
If that's ok, then i'm lost too, sorry

perhaps, if i could unlock again my phone with flashtool in order to flash a kernel...
but, plugin menu is empty.
No idea to force something to have plugin menu available to unlock ?
Nevertheless, thanks for your help
I have no idea, the unlock bootloader option is only available if you're on 2.1 (eclair) 2.2 (froyo) or 2.3 (gingerbread), and your phone has ICS at the moment, so that won't work i guess... i am really lost about your problem, I would think maybe try the repair a few more times, maybe SE had a server problem or something, but other than that, i don't know...
I wish you luck
one last thing...
maybe repair your phone with your sim-card removed may do the trick...

I've read somewhere that other people with french firmwares have trouble updating via PC Companion and things, maybe you could flash the nordic or uk firmware that is lying around on the forums here in de dev section and then try a repair after that,
You can flash firmwares with a locked bootloader, just not kernels. (sorry, i hate to see such a lovely little phone go to waste)
You can still select french as your language if it works...
http://www.multiupload.com/GM4VW1LNVV and choose the rapidshare link, the other ones are down...

but could you help me again ? in your zip file, which file should i flash ?
Is it nordic or uk firmware that you speak or another thing ?

It is Nordic, but i don't think that will be a big problem
You unpack the .rar file and put the .ftf file into the firmwares folder found in the flashtool-installation folder
Start Flashtool - Press the flashbutton, choose the .ftf you just put in there and connect your phone in flashmode.
If the flash is succesful, turn off your phone and try a repair with PC Companion.
Fingers crossed...

Should i rename a file with .ftf extension and in this case which ?
Thanks
Sorry, i found the possility to create firmware in flashtool with these files
After flashing, i success to update with pc companion (not with seus)
But i am again face to my original problem, the phone doesn't see the sim card (i tried with others sim card from different operators)
I don't know if you have an idea about this issue, but nevertheless, thanks a lot for your help
Try the steps in here, It may work..
Basically,
(I guess your bootloader is still locked, otherwise, lock it again)
do a repair without your simcard in your phone
do a full boot without the simcard
once it's booted, don't set up anything, but turn your phone off again
put your sim in, and reboot

Xperia Z Ultra (C6833) - SIM not recognized

I'm new to this forum and I hope to get some help from the community...
Device:
Sony Xperia Z Ultra (C6833), Android 5.1.1 (Lollipop) rooted, Built: 14.6.A.1.236 , Developer's mode & USB-Debugging enabled
Problem:
After updating SuperSU to 2.82 I had a bootloop. Did shutdown using small red button, restarted using recobery mode of TRWP (2.8.7.0) and did factory reset. Everything works again (WLAN, Apps, SD card access) but except the SIM card which is not recognized. IMEI not shown "About the phone", but correctly shown in diagnosis tool
Already tried:
- SuperSU 2.82 installed manually via TWRP. Works.
- Restored a full backup Sony PC-Companion, no success. Same with a Snappea backup.
- SIM proofed with different cell phone, works
- Other working SIM card tried with this phone, no success
- I blew a couple of times into the SIM card slot, no success
- Flashed the full ROM (14.6.A.1.236, rooted), no success
- Tried another factory reset, no success
I guess, there is a problem with the modem driver for the SIM card reader. Any ideas how to fix this?
I'm a newby to root & stuff but I'm hoping, that somebody could help me. I'm very thankful for any hints!
Greetings from Germany!
Not sure how the imei got tweaked by updating the supersu..?
But I had the same bootloop with the new supersu on latest stock rom rooted.
Manually removing all root and manually flash the new via twrp didn't work for me either.
Flashed the old supersu and it boots fine.. so I just keep the update in playstore and don't press it.
Perhaps I will repack the supersu app to generate a unique file signature so it won't show up in play store on installed apps.
Perhaps the simcard got tweaked in the tray when you pushed the red button somehow? ...I dunno. Just a thought.
I have had issues with mine too. The tray is very flippy floppy and have gotten stuck several times inside the phone.
But have you tried flashing stock rom with flashtool?
http://www.flashtool.net/downloads.php
Make sure that none of the options is ticked in "exceptions" so all partitions being flashed.
Do you know how to use flashtool?

Hi SUPERUSER, thanks for your quick reply!
It can't be the SIM card itself, since it works with my other phone. Also tried my GFs SIM in the C6833, also failed. Should be a ROM problem.
Tried to go back to SuperSU 2.79, 'cause that's how this mess all started (updating SuperSU), have the bootloop again, went back to 2.82. Works fine except the undetected SIM card.
Also tried 2 (probably dirty) modem fixes, this caused also loose of IMEI. Went back to my full backup using TWRP, where everything works (IMEI ok) except SIM card problem.
Just installed the flashtool, but it says, that the bootloader is locked. Unlocking it officially thru Sony website (developer.. sonymobile..com/unlockbootloader) requires installing full Android Suite (1.9GB) and further driver installtion using SDK manager. Is this the only way to use the flashtool? Other question regarding the Flashtool: Tutorials say: Copy ftf-File into the "firmware" folder, but there is no folder with this name. I checked the entire flashtool folder tree.
Isn't it possible to flash ROM in zip-format only using TWRP? Should I give DualRecovery a try too?
Thanks a lot! Appreciate your help!

Whats causing your problem is probably that your bootloader is locked.
But I'm not getting how you use twrp and flashing files if the bootloader is locked?
You can flash stock roms with locked bootloader. It dont require to unlock it.
You don't need to download the whole SDK for just using fastboot.
If you need fastboot you can download fastboot from here: https://forum.xda-developers.com/showthread.php?t=2588979
After install choose the right driver for your togari in device manager to "Android bootloader interface"

Fastboot sucessfully installed using your link, but I have a driver problem. The device works fine connected to the pc using Sony PC Companion oder Snappea. Do I need a different driver for running fastboot? Found "S1Boot Fastboot" in "Devices and printers" on my pc and I'm aware that the correct driver has to be installed manually, just don't know where to get it. Google didn't help much, I'm only found a zip on Sony web, which probably does not contain the one file I need for running fastboot.... Any hints?

PC companion is screwing you over because it has its own signed drivers. Perhaps these are proprietary and don't work with universal fastboot.
If you installed the 15 seconds ADB Installer v1.4.3 from the thread I linked AND installed the google driver when you were asked if you wanted.
Connect your phone in fastboot. Then choose the driver manually from a list. Scroll down to "Android Device" and select "Android Bootloader Interface"
You will get a warning that the driver might not work. Click yes and soon the device will be found and your phone will respond to fastboot commands.
If you need all drivers for example the flashmode driver you can download and install flashtool.
Then you get a folder with a driver pack in C:\Flashtool\drivers. The executable contains all the drivers to every xperia device.
Edit:
If you ever need the driver pack from flashtool I uploaded it to mega:

Cheers! Couple of steps further! Drivers installed, fastboot detects the device now, I unlocked the bootloader successfully using fastboot. Device now recognized by the Flashtool too.
How to flash the custom ROM now? Better using fastboot or the Flashtool? I'd prefer the flashtool due to my limited cmd experiences. But I don't know how to select the FTF-file, which I already downloaded.
Don't know how to add screenshots here directly, so I added 2 attechments: Flashtool Main Screen and Folder sctructure of Emma. There is no "firmware" folder where I can drop the FTF-file to.
If using fastboot, ftf-file won't work, right? Zip-Files only?
How to proceed? Cheers, again!

You downloaded the SONY EMMA flashtool. Not the one we need.
The name is a bit confusing because they are called the same.
The flashtool we need is this one. Download it via torrent its the fastest way.
http://www.flashtool.net/downloads.php
Uninstall Emma and install this flashtool.
...time for some ugly doodling
When you are done installing flashtool and are met with the UI you will see a main window as in image one. Press this button on the far right with the XF logo.
A new window will open with the name XperiFirm as in image two. Scroll down the list on the far left until you see the Togari.
Select your device. In my case I have the C6833. Now go to the list in in the middle. Click the "check all" button to fetch all updates.
When this is finished you will see a the latest "version number" on every "operator" in the collumn to the right.
Click the stock rom you would like to download in the list that correspond to where you live.
I always download customized DE because it includes the region I live in. Now look at the list to the right.
A list will appear under the "Available Firmware:". Click on the one you want to download. In this case there is only one entry.
Almost all older stock rom has been removed lately so it is very rare that you will find any old based on jelly bean or kitkat.
Anyway. When you click the one you want to download a new window will open as shown in image three
You will see some info. Double check the name is the one you want to download. If its right. Click download and make a coup of coffee.
When the download is finished you can close the window and let flashtool do its job. When its done.
You can see it in the log when it says its finished.
Now you want to press the button all the way to the left. That thunderbolt icon as shown in image four
A new window will open. Select flashmode and press ok as shown in image five
A new window will open and here you can see a list of which stock roms you have downloaded as shown in image six
Select the one you want to flash and look to the right in the "Exclude:" box. Make sure nothing is ticked.
And press flash when you are ready. And follow the instructions following by flashtool when it is ready.
Optional
If your phone is not detected in flashmode you need to install S1 - flashmode driver. You can do so by follow these steps.
Go to this folder as shown here in image seven
Execute the file as shown here in image eight
Select Flashmode Drivers as shown in image nine You don't need to select fastboot drivers. Because you already have this working.
If you want you can scroll down and select Xperia Z Ultra drivers as shown in image ten however this seems to fail in Windows due to driver signature verification.
Its not necessary to select it. Click install and hopefully the device will be seen when connected in flashmode.
For zip files. What you find here on the forum. You flash these in recovery. Not very difficult. You can find loads of guide on how to get started learning how to use recovery mode.
.img files. You flash via fastboot with cmd. Not very difficult either. Key tip here is to don't make typos or you need to rewrite the whole command again..which get boring fast.

Followed all your instructions. Custom ROM flash with (the correct) Flashtool was succesful. Now comes the hopefully magic moment, where I'm gonna reboot and see if SIM card will be detected....

SIM card NOT detected. I'm freakin' out!
Again tried the SIM card in 2 other phones, no problems. Tray and contacts shouldn't be the problem either, because I didn't to anything with SIM card and tray when the problem came up first after the stupid update of SuperSU and the following bootloop. Just pressed the tiny red panic button to shut down and went into recovery mode.
Just tried to use some thin folie between the tray and the SIM card in order to have some more pressure between SIM card and the contacts, failed.
Is it technically possible that a full custom ROM flash (with no ticked exceptions) still not formated the probably damaged SIM card modem portion/driver?
User pintspin has the same problem as above and he is much more into the topic than I am.
Still any hints? Wanted to avoid buying a new smartphone, still love the Ultra C6833 and its large screen...

I will ask him if I can obtain the ones that worked for him/her.
The modem should be flashed when you flashed the ftf file if the baseband portion is included.
This is the one I found in the thread ResurrectionRemix 5.8.3 25/05/17 [7.1.2] Nougat for Togari,
https://forum.xda-developers.com/showpost.php?p=56234199&postcount=16
And this:
https://forum.xda-developers.com/xperia-z-ultra/help/aosp-rom-sim-detection-t3185526/post62481536
I know I have used one other way back. It was two zips. You flashed them in a specific order or the phone would not boot.
But I can't find this one.
I uploaded my own modem files. Its the same files that is in the zip above but with the stock rom Im running.
Im guessing it might do something because its working on my phone. And its the same files that is being flash in the above zip file.
File is not flashable. Unzip and replace the in system/etc/firmware. Permissions 644. And reboot.
Or you could do it from twrp. Take a bit longer. Manually delete the three files one by one and then copying the files one by one.
Setting the permissions to 644 one by one.

@SUPERUSER done , uploaded here the working modem patch strangely from a different variant but worked fine... thanks for above help as well.
I can confirm that the attached modem patch is working perfectly fine ... on AOSP build ( 6.0.1 )
(*) @ac845 steps i suppose you already have your system.img and boot.img
Flash the aosp Rom images ( system.img ) and (boot.img) via fast boot OR if you dont have images of stock then just flash any stock rom zip from recovery i used twrp recovery after FULL WIPE OR if you even dont have both then just use Scrubber port GPE for togari 6833 z ultra
don't reboot
Flash the attached modem patch i.e. C6802_modem_patch.zip
reboot to system
on first boot it will take a bit ( 1 minute may be ) to detect and register the sim.
I have finished worked on my rom as well , will going to upload it hopefully today ... its purest aosp stock , can be rooted and gapps are also tested working fine , there is no Imei base band issue as well.

I (partially) understand, what you guys mean, but I don't know how to proceed and thus have to ask more beginner questions:
As recommened by SUPERUSER like 2 days ago I flashed a the .276 stock ROM. The device is of course unrooted now, bootloader open. I don't have a recovery mode (f.i. TWRP) where I can flash ZIPs. What would be the easeast way to flash a ZIP-file in this situation? I could try flashing with fastboot, but I don't know where to get the right .imgs. Wished I still had TWRP though. Sorry for bothering you, but for beginners like me it's too complex sometimes...

Download this file https://www.androidfilehost.com/?fid=24415232478676273
To make it more simple. Rename the file to "recovery" without the quotes when the download is finished.
In your download folder on your computer hold down shift on your keyboard and right click on an empty space.
In the right click menu select "open command window here".
In the cmd. Type "fastboot flash recovery recovery.img".
Turn your phone off. And boot it to fastboot. Hold volume up or down and simultaneously connect the usb cable to the computer.
If you did it right the phone should have a blue led on.
Now press enter on your keyboard inside the command window.
Hopefully you will see something like flashing and then finished.
How to boot to recovery?
Pull out the usb cable.
Now hold volume down and press power button.
When it vibrates let go. A few seconds you will se the twrp ui.
In addition to super user post above : For fast boot you need to press volume up and then connect PC USB cable when your PC is on and USB cable is connected to it ( you also need yo ensure that USB debugging is turned on ) goto phone setting and you need to press 8 times on build number in your about phone n phone will open a hiden option called developers option under phone settings and goto developer options n under that option you need yo select USB debugging on .

TWRP succesfully installed. Great to have it back!
But now it comes: SIM CARD DETECTED AGAIN after 2 weeks and endless hours of fiddling, reading forums and bothering you guys. You both are awesome :angel: and made my day!
What I did:
1. TWRP installed
2. full wipe
3. installed prerooted custom rom 14.6.A.1.236: Customized Germany (DE), source: https://www.android-hilfe.de/thema/stock-roms-mirror-root-tools-anleitung.559556/ Link: https://mega.nz/#!PoEElBZa!DlejjkTzCZGMXbJR0ZvgTk5i0gNqo4QSM0LIyyRKl1M
4. installed SUPERUSER's modem patch from above
5. rebooted: 1. time no SIM card detected. Wanted start crying :crying:, but rebooted 2nd time: SUCCESS! Broadband of my provider is back!
Now restoring messages, contacts and apps right now using Snappea. After reorganzing apps I'll do full TWRP backup and I hope that this problem never will occur.
During restore app process I'll go to a German beer garden and will raise my glass to you guys! :laugh: Want to donate both of you some money, please let me know how. Paypal?
Greetings from Germany!
George

Unfortunately it's not over yet!
SIM still not detected very often, but sometimes it does. SIM works for some hours but then it's accidently not detected anymore in locked-screen mode or in the middle of operation, app usage etc. Rebooting with detected SIM works in 1 of 5 times maybe. Restoring full backups doesn't make any difference.
Had the idea that it is a temperature problem and cooled the device down in the frosting fridge for a couple of minutes, but rebooting incl SIM detection works more often, but not always. Beside SIM problem operation is normal, no problems with WLAN, apps etc.
IMO it can't be a software bug since problem occures not generally. Before I'd send it in to Sony I wanted to ask the community if you have any ideas or recommendations?
Cheers!

Help to upgrade to Oreo

Could someone please tell me a step by step how I could upgrade my xperia x to oreo using xperifirm?
because I've already downloaded the firmware in xperiafirm, I activated debugging and I gave the flash just to update, but it just does not update, nothing happens.
the version of my firmware and Brazilian and until today the sony did not release here.
If someone can help me, I would be grateful.
Obs: I already placed the fsc file in the F51XX folder and it did not work.
Xperifirm is just a downloader!
its FLASHTOOL who creates BUNDLE of those downloaded firmware ( C:\Users\<username>\.flashTool\firmwares\Downloads)
however if you have ran xperifirm independently, you will have to create ftf bundle manually from FLASHTOOL. which is itself is a long process!
i would suggest, you run xperifirm again from FLASHTOOL (open flashtool and at the buttons click XP button) , download your firmware AGAIN. and once download complated,
1. close the download window
2. close xperifirm
3. immediately FLASHTOOL will be triggered automatically to create BUNDLE of new downloaded firmware.
4. it will ask FSC cript dialog box, click OK/YES and flashtool will create ftf bundle in next 10 mins at C:\Users\<username>\.flashTool\firmwares\
once done

[SOLVED] U20i - Going back to stock software/firmware in 2019

I've had a little nightmare and spent a whole day trying to get this ancient Xperia X10 Mini Pro (U20i) to the stock software, so I thought I would share with you how to do it in case anyone needs to do the same. (In my case I did this to get £100 cashback trading in the U20i for a new phone -- with according to T&C could not have modified software)
So what you need is:
- A copy of the U20i firmware, this comes on an FTF bundle to flash with Flashtool - Get these from here (Live June 2019): https://www.mediafire.com/folder/m07tam9mit6jj/X10_Mini_Pro_(U20)
- An old version of FlashTool (as the latest does not work with the U20i and other older phones), this link has the flashtool-0.9.0.0 for windows: https://drive.google.com/uc?id=0B8HYFIy2LVm5OUVxczI0WEdIbjg&export=download
The process is pretty simple:
1 - Install FlashTool 0.9.0.0 in Windows
2 - Once installed go to the drivers folder and install the drivers for U20i/your phone + flashmode & fastboot
3 - Place the FTF file downloaded from above in the 'firmwares' folder.
4 - Press the first icon (lighting icon) and connect using 'Flashmode', the program will tell you how and what to press.
5 - Select the U20i stock software (that you downloaded and put in the folder as per step 3) from the list
6 - Press flash and cross ya fingers!
NOTE: THIS SOFTWARE IS ONLY VALID FOR U20i BASEBAND M76XX-TSNCJOLYM-53404015
If you flash it to any other phone/baseband you will brick it. However, use these instructions to fetch your own software for other models. GL with that as most links seem broken! ​

Found an old Xperia mini in the trash and the phone seems to be soft bricked, stuck in sony ericsson bootloop, tried everything i could think of. Found a .FTF file for it and tried flashing it with flashtool, flashtool says its flashing but nothing happens. Also tried all versions of xperia/sony ericsson PC companion for a normal software repair, but nothing seems to support this phone anymore. I could of course buy a working version of this phone for about 2-3 bucks on ebay but where's the fun in that? I've been playing around with android phones a lot in the past but I cant figure out how to proceed with this one.
I followed your guide, but flashtool (v0.9 something) doensnt find the .ftf file in flashmode, I can only install via .img, .sin and something else in fastboot mode. Flashtool recognizes the phone correctly both in flashmode and fastboot mode but doesnt seem to do anything.
Any pro tips on how to proceed? Thanks
