[Q] FlashTool: Downgrade not working

Hi all,
I'm trying to downgrade my stock Lollipop ROM (23.1.A.1.28) in order to root it afterwards. I'm using FlashTool 0.9.8.15 on Linux, and it seems to work correctly - but the downgrade fails
Here's the log output of FlashTool:
Code:

Opening that FileCommander coming with the ROM I get the info that there's 11.6 GB free on the phone and all 59,4 GB on the SD card. So - how's this??? And (more important): How to fix it?
Thanks for your kind help

Where have you stored the FTF?

Argh, the problem was so easy to solve - I just had to understand that error message - my hard drive simply got filled up when FlashTool tried to unpack the FTF :-/

Hi, I'm trying to do the same thing. I'm using flashtool 0.9.18.6 on windows 8 computer. I keep getting an error prompt stating "processing of loader.sin finished with errors."

Aplication has stopped after installing Project Desire One

Hello.
Today i tried to flash soundmod Project Desire One, The Evolution. Downloaded package from HERE, reboot into recovery, use TWRP to flash this and clear dalvik + cache. After this I get app "My Xperia" stopped and it was showing all the time. I did factory reset on my phone and then i come up with this : LINK DO PICTURE. What i can do ? PC Companion says that I can't repair this phone. I can't use adb, cause phone is after factory reset. I tried be faster than pop-out, but it's impossible.
What should I do ?

Try to ask in this thread maybe someone will help you cause it seems flashtool need an update for the script thing http://forum.xda-developers.com/showthread.php?t=920746

I recently updated my FT to 9.19.10 and now when I'm tryin to flash E6633 it stops all the time at "Start Dumping TA partition 1". I'll wait for answer in theyr thread.

Make sure to read the OP cause any mistake can brick your phone.

OK, uninstalled Flashtool with deleting files from C:/Users/xxx/.FlashTool then downloaded 0.9.19.8 and patched it to 0.9.19.10. Flashtool started normally and I sucessful flashed ROM and kernel.
Phone is working now well. Thank's for help

Good to hear.

Anyone....?
Last night when it had ~5-10% battery and was charging very slow, don't know why it didn't restart, i was playing on the phone every 4-5 minutes and no reboot.

You have to be kidding...at least some little advice, ask me something about the problem...say something XDA....
-should i try to flash it in fastboot mode?
-how can i erase the "prototype" thing?

Hi Bro. Let me guess did you buy it from AliExpress right? I've same issue like you bro. When i use the sony PC companion to upgrade xperia version to newest update. It doesn't work got a error like "Error code: UELoginAuthenticationFailed UE_1100" So i never give up my challenge i used Xperia Flashed tool and it works for me. Anyway after update it to Marshmallows i have huge battery drain issue. So i like to know did you find any solution for your issue?

Soft Brick After Trying to Flash Latest Stock Nougat Firmware via Flashtool

Hello XDA, longtime reader, first time poster.
I tried flashing a custom ROM the other day, but something went wrong, and I now have a device that bootloops (unlocked screen, SONY logo, followed by a "the software update failed" message). I think the cause of all of this came from a few missing drivers that Flashtool/Windows 7 didn't install properly. I'm not sure if this matters, but this happened after trying to update to the latest stock nougat firmware (downloaded via Xperifirm) from a custom 6.0.1 ROM.
I went through as many solution threads as possible, but I'm still having trouble. The last thing I did just before this post was create an ftf via Flashtool, added "41.fsc" script when asked, prepared flash with full wipe/no exclusions, connected phone to USB via Flash Mode, selected F83XX when prompted for device, and this was the log I received...

Extra information...
PC
- Windows 7 64-bit
- Flashtool 0.9.23.2 installed
- As far as I know, every driver I need has been downloaded and installed (Sony's website, Flashtool-drivers.exe)
(↑ "Sony sa0115 ADB Interface Driver" under Device Manager reads "This device cannot start. (Code 10)", if that makes any difference)
- Xperia Companion doesn't detect my phone, so I can't use their "software repair" option
Phone
- F8332
- Bootloader unlocked
- *Backup TA missing*
- Device rooted
- TWRP 3.1.1-0 installed
- Android 6.0.1 (firmware unknown)
Files
- Latest Nougat firmware (F8332_Customized FR_1305-9679_41.2.A.7.76_R1D) -- folder only (ftf can be created anytime, just need to know what to keep/exclude. I've been seeing different answers regarding when to add "41.fsc" to ftf (before/after flashing, or adding at all), and excluding .sin files before flashing, so if anyone has a definite answer to these, I'd really appreciate it.)
Otherwise, if none of that matters and the problem lies somewhere else, I'm all ears.
Thank you in advance.

@simpleflips
wow - your post should stand out as a prototype for HOW TO ASK FOR HELP!
I had the same problem recently when trying to flash my F8331 under Windows 10. Did not try Linux on the same machine since there are some issues with Mono here.
My drivers where not giving me any clues (PC-Manager, logging under Windows?).
So I dug out my spare laptop (Win 7 bitness?): installed the XZ-driver and it worked there after a full wipe in TWRP (I had encrypted the device and TWRP did not take the key properly).
You can try the drivers I link in my Guide.
Under both Windows installations I had no problems with adb and fastboot.
So I can only guess that my "solution" was the full wipe or some unkwon differences in driver magic between the notebooks used.

@DHGE
Apologies for the delay, thank you for the words and response. I should've noted that before my OP and bootloop, I tried to flash the custom Nougat ROM via TWRP, but got an error. (Zip file is corrupt! Error installing zip file '/sdcard1/[rom].zip') (Tested after transferring the file via AirDroid, don't remember if I even downloaded directly from my phone.) Now if I run a full wipe through TWRP and re-flash the original 6.0.1 ROM that's in my microSD, it *does* install, but bootloop still exists. I tried wiping/flashing the custom ROM via fastboot out of curiosity, and received the following:
wipe (entered bootloader mode from my Downloads folder, where the ROM is found)
C:\Users\[name]\Downloads>fastboot -w
Erase successful, but not automatically formatting.
Can't determine partition type.
FAILED (status read failed (Too many open files in system))
Erase successful, but not automatically formatting.
Can't determine partition type.
FAILED (command failed (Invalid argument))
erasing 'userdata'...
FAILED (command write failed (No such device or address))
finished. total time: 0.020s
(Afterward, I get a message saying fastboot.exe has stopped working. Not on Minimal ADB, though.)
flash
C:\Users\[name]\Downloads>fastboot update [rom].zip
'archive does not contain 'android-info.txt' ,
error: update package '[rom].zip' has no android-info.txt
Do these errors relate with each other? Was my file just not downloaded properly?
Regarding the drivers, I downloaded the official Xperia XZ ADB interface driver (Sony sa0115) from SONY's website, and installed via Device Manager, but get the Code 10 Error mentioned in OP. According to some user posts, the solution was changing their phone's USB configuration to MIDI, afterward Windows would properly detect and install the Sony sa0115 driver. (I reckon that's not possible on a soft bricked device, is it...?) No devices are found after entering adb devices in command prompt, so I'm going to presume installing/flashing anything via ADB is out of the question. Right now, Device Manager shows 2 devices-- One of them being the actual XZ when connected in fastboot mode (labeled "Android Phone"), the other being the Sony sa0115 driver I downloaded/installed. The trick now is mounting the two together.
At this point, fastboot/TWRP seem to be the only way out of this. The custom ROM notes that no kernel flashing is necessary, but your guide includes a link to the AndroPlus kernels (for stock, and other roms, I take it). Unfortunately, until I figure out how to properly flash the firmware via Flashtool, AndroPlus will have to wait. (Unless there's a way to find out what firmware my phone is using right now.) The next option is to directly send the custom 7.1.1 ROM from my PC to the microSD card, but I can't find my SD card adapter right now, so I'll update later this week.

Unfortunately this is not a way out. And what you wrote above sounds rather weird for me...
The only way out is to flash a SONY ROM properly. THE tool for this is flashtool.
There are some mentions of SONY's recovery tool(s?) but last time I tried one I could not get it to work. Flashtool to my rescue.
Maybe you can take your phone to a qualified repair shop and they flash you a SONY ROM.

Help

Hello there
I had the same problem with my Xperia Z2, so I found your thread while searching for a solution. First "Bundle does not match device" and then "root: This bundle is not valid" .
I could just solve this (strange) issue, so here are some tips how I managed it:
I assume that you installed the newest version of flashtool (0.9.24.4)
- uninstall/remove flashtool (0.9.24.4)
- Download the previous release of flashtool (0.9.18.6) and install it click
- Install the drivers of your phone (directory of flashtool -> drivers)
- Launch flashtool -> Xperifirm -> Download the correct Firmware (again). Make sure that your home-directory of flashtool (default: C:\Users\xyz\.flashTool) is empty (at least no .ftf file may exist)
- Let flashtool create the .ftf File
- Flash the .ftf
At least this worked for me. If it doesn't work for you, you could try to use Sonys official developer Xperia Flashtool ("Emma"). This application saved me once or twice already from severe situations.
BUT WARNING: I'm not entirely sure anymore, but I think it erases your entire internal storage (incl. pictures, music, documents, some appdata, etc)
So if you can still get into TWRP, make a full backup of your personal data (with adb or simply drag'n'drop or whatever you like).
Usage is very simple and self-explanatory: Download -> install -> connect Phone -> install Firmware (downloads it automatically)
PS: I don't know why you're experiencing a bootloop and what ROM you're using, but this little idea came to my mind what you could try:
Wipe dalvik/cache and flash your boot.img again with fastboot
I used this little trick several times with success, but only with Custom ROMs (Ressurrection Remix, Lineage, Carbon). So I can't tell anything about Stock-ROMs.
I hope I could help you

I could just solve this (strange) issue, so here are some tips how I managed it:
I assume that you installed the newest version of flashtool (0.9.24.4)
- uninstall/remove flashtool (0.9.24.4)
- Download the previous release of flashtool (0.9.18.6) and install it click
- Install the drivers of your phone (directory of flashtool -> drivers)
- Launch flashtool -> Xperifirm -> Download the correct Firmware (again). Make sure that your home-directory of flashtool (default: C:\Users\xyz\.flashTool) is empty (at least no .ftf file may exist)
- Let flashtool create the .ftf File
- Flash the .ftf
. . .
I hope I could help you

Thank you so much for that answer. I spent hours trying to find a solution, but using an older version of the software would never have occurred to me. Thank you so much for that answer.

emad

我的Z5P Dual E6883 閃光成 E6853之後無法復原 終於在0.9.18.6得到解決的方法 無法表達如此感謝

I can confirm that it works by using the older version of FlashTool, with an Xperia ZR :good: I also disabled the "verification" part as this posed some problems with reading from the device. I was able to install two different types of .ftf files (one at a time), and then reinstall recovery and LineageOS. My original problem was a bootloop, only showing the TWRP or Sony splash screen beforing screen going black again and rebooting.

At least this worked for me. If it doesn't work for you, you could try to use Sonys official developer Xperia Flashtool ("Emma"). This application saved me once or twice already from severe situations.
BUT WARNING: I'm not entirely sure anymore, but I think it erases your entire internal storage (incl. pictures, music, documents, some appdata, etc)
So if you can still get into TWRP, make a full backup of your personal data (with adb or simply drag'n'drop or whatever you like).
Usage is very simple and self-explanatory: Download -> install -> connect Phone -> install Firmware (downloads it automatically)
PS: I don't know why you're experiencing a bootloop and what ROM you're using, but this little idea came to my mind what you could try:
Wipe dalvik/cache and flash your boot.img again with fastboot
I used this little trick several times with success, but only with Custom ROMs (Ressurrection Remix, Lineage, Carbon). So I can't tell anything about Stock-ROMs.
I hope I could help you

Thank Youuu !!!! You made my day . I was stuck here for around an year . It never occurred to me to try an older release of flashtool. :good::good:

LOL! Newer is not always better haha. I just ran into this issue while trying to flash my Xperia Z2 back to stock. It was showing "Unknown" and complaining with "The bundle does not match the connected device" then refusing to flash. I thought it had to do with the LineageOS kernel it was running at the time, but no, flashing a stock-based kernel didn't fix that either.
Thanks for saving me from a headache!
