[SOLVED] U20i - Going back to stock software/firmware in 2019 - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

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

What is the difference between this ROM and build 2.0.1.A.0.47? My Xperia X10 Mini Pro (U20a) officially gets 2.0.1.A.0.47 instead of 2.0.2.A.0.24. Can I safely install this version instead?
Thank you in advance.
Never mind, I already found out that this is a more recent version, it is basically the latest update that SE released for the X10 family.
I installed this ROM on my X10 Mini Pro U20a and can confirm that it works like a charm, thanks so much. Great job! I have root access and so far everything is working perfectly. I will proceed to delete some bloatware and finish restoring backups and configuring system settings.
xRecovery is simply awesome, especially taking into account that it is in such an early development state.
I'm incredibly happy with this update. Thanks to shivenjuneja, Bin4ry, zdzihu and aZuZu for the hard work and for making this possible.
Thanks man m happy u like it.
Hi cheers for info etc, just a quick question, I uploaded xrecovery for the x10 but it doesnt seem to work on the mini pro my phone is rooted etc and has busybox
I have tried the xrecovery for the mini pro but as it has to be installed via root explorer, not sure how to do it, even though its explained
Cheers Steve
Assuming you currently have root access.
Just download xRecovery here, then extract the three files and copy them to the /system/bin folder. Finally, reboot your phone and start pressing the back button repeatedly as soon as it starts booting up again (don't wait until you see Sony Ericsson on the screen, start doing it before). xRecovery should start right after the white Sony Ericsson logo.
was happy with it until i realized there may not be many themes or roms for this fw version, downgraded
u can use any theme on this framework just copy services.jar,framework-res.apk,android.policy.jar,framework.jar from the old framework to this...
Can anyone from brazil post here a build.prop for 2.0.2.a.0.24 (x10 mini pro U20a)??
now you can root your mobile using the application no need of flashing the firmware... u can find it here
shivenjuneja , work whit Black HTC Theme or only for themes of 2.0.2.A.0.24?
Nice work ...
Thanks a lot for this! I reflashed my mini pro with this firmware to change back to U20a to get 3G and it's working great
but this firmware change the language ? I've a italian x10minipro
Anyone else having issues with the gps?
Anyone else having issues with the gps? I seem to lock on to a signal, but Ndrive keeps telling me I am off any road. It was working great with 1.6. Other than that, this is rock solid
have 3G lost Wi-Fi
I have two of the Xperia Mini Pro handsets, one is flashed with the u20i firmware ( I should be using u20a) and it works well enough
But flashed the other with the firmware for this country and my carrier(u20a) and the 3G is flakey (probably the carrier) but I can't connect to any Wi-Fi networks.

It's a problem with a corrupted wpa_supplicant.conf file
delete it with root explorer (making a back-up just in case) and re-boot

Thanks to this thread I have had a fully functional u20a Mini Pro for quite a few weeks and we have been getting along quite well and I now want to take the relationship a bit further - to the next level.
That is to say, I want to update the Build Number from 2.0.2.A.0.24 to, oh I dunno, 2.1.1.A.0.6
I haven't been able to get it from SE so I'm hoping that someone here might point me in the right direction.
New U20a Firmware
I also would like a copy of Firmware 2.1.1.A.0.6 for Mini Pro U20a. Is any one able to share a up copy please

Accidently flashed mini pro firmware unto mini. Can't undo?

Hi, I recently got a x10 mini and in a rush to gain root etc.. I accidently flashed U20i-mini pro update_1.0_2.1.1.C.0.0tft and now can't flash any x10 mini firmwares of which I have tried 3 different tft files and even tried bundle creation under advanced settings in FlashTool_0.2.9.1_ and none of these are working.
I've done a bit of searching and the general consenus seems to be just use SEUS and it will all be o.k but it just says there is no software update for my phone
The other weird thing is that I can seem to be able to flash other mini pro firmwares with no problem which boot up fine but I am unable to use the touchsreen so can't access features such as enabling USB settings and unknown sources
Any help anyone could advise I would be very grateful!
Ok man, dont be afraid, try to do this:
1st - Open PC Companion
2nd - Select Support Zone
3rd - Start Phone Update
4th - Select "repair phone"
5th -follow instructions.
Here is a video I did showing what do to:
http://www.youtube.com/watch?v=NuvzapI0MEw
Thanks for the reply I have tried what you have suggested but it also doesn't work it gives the same result as SEUS and PC Companion that software is up to date and the only option is to exit program?

This is weird. My SEUS still allows me to install the firmware even if the phone is up to date...
I remember there is a restore button in the program...
You can try that way if you have the recovery installed and you can access to it :
plug in your phone
open pc companion,
access to ClockworkMod (the recevory program on your phone)
go to mount and storage and select mount usb storage
now come back to pc copanion, click on support zone, start phone update, select repair, and wait for 30 minutes.
Unfortunately I didn't get as far as gaining root as I can't use the touchscreen.
I even managed to flash a 1.6 version of the experia mini pro via flashtool but it stills says that my software is up to date and again only option it gives is too exit program??
Just can't really understand why it will flash mini pro firmwares but refuses mini firmwares with Flashing loader. Error.Flashing aborted.
I also notice that the main diffrences between mini pro and min firmwares is the inclusion of dsp1.sin in the mini tft files, could this have something to do with it?

[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-----

What should i Do now One thing more i was goignaround the threads looking for solution So in one thread it said that firmware can ber installed through flash tool 0.2.5
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)

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.

-Download frameware 2,3,3 (it's in ftf extension,if not so rename it!)
-Download flash tools pc app (Linux, windows) then install
-Put frimware.ftf to frimware folder of flashtools(it installs by default at drive c:/flashtools)
-turn off your phone
-run flashtools then press lightning button, & choose flash-mode
-select the frimware & press next
-you'll be asked to attaching your phone ,so hold back button then pull USB cable in the phone
-flashtools will do the rest of flashing automatically
Then you can turn it on
#drivers should be installed
#wrong frimware = hard brick
(If this is hard you can use pcc to repair & update your phone to the lates frimware)

Hi and welcome to xda!
If you wish to revert back to the stock GB firmware this is the easiest way if you to do so:
1. Turn your device off. If you for some reason can't turn your phone off properly then pull the battery out and wait 10 seconds.
2. If you took your battery out then put it back in. Do not turn your phone on and open SEUS (Sony PC Companion) on your PC (you can download it from the Sony website or simply google it).
3. Click on Support Zone > Phone / Tablet Software Update > repair my phone / tablet > follow instructions and connect the phone in flashmode when asked for (it will tell you how to do that).
4. Wait till SEUS does it thing and tells you that everything is successfully done. DO NOT DISCONNECT THE PHONE FROM YOUR PC WHILE MAKING A SOFTWARE REPAIR!
5. You should be able to use your phone with the stock GB ROM installed.

[HOW-TO] Unbrick your XZU

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

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?
