### How to downgrade from 6.0.1 to 5.1.1? ### - Xperia Z2 Q&A, Help & Troubleshooting

Hello, i'm getting an error when trying to downgrade my xperia z2 from 6.0.1 to 5.1.1. It says: "Processing of system.sin finished with errors." and the phone gets bricked after i reboot, "Software update failed, make sure that your phone is connected to the computer and try again". I have to use xperia companion to repair the phone.
I've tried everything but couldn't solve this error. Tried flashing with both usb debugging on and off, tried with 2 different stock rom 23.4.a.232 to no avail. What am i doing wrong?
You can see the log at here: http://textuploader.com/5erjb
-In case i can't solve the problem, is there another way to downgrade the firmware?
Thanks in advance.

If you don't know how to downgrade, I don't think you belong here. It's the most basic stuff.

Please post in the right section. Have you tried Googling this error?

use flashtool version 0.9.18.5 and uncheck "unknown" if u see that on flashing partitions

Download 5.1.1 ftf by using xperifirm.
Download and install latest flashtool.
Run flashtool and click flash button. Choose flash mode and then select your ftf file.( note: exclude all .ta files specially simlock.ta)
Now connect phone in flash mode. Switch off then press and hold volume down button while connecting cable to pc.
Then flash ftf. It will take some time to flash so wait. And do not disconnect in between.

Please Help, tried to Flash phone, Error phone Cannot Reboot.

Hey Guys, I hope you are having a good day. Mine is not a good one.
I wanted my experia st15i phone to be back on stock again so I can root it. I am running a .62 firmware. I have read on doomlords thread that .62 firmware cannot be rooted, so I decided to flash it back to the stock phone .368.
I followed all the step on the flashing on the phone.
-downloaded the flashtool for experia latest version. Followed the steps
- installed the necessary drivers -adb, flashtool drivers.
- then I followed the steps to flash the phone
This error came up (see Attachment) after that I haven't been able to turn on my phone since then. Even If I tried again, still comes up the same error.
BIG PROBLEM! My phone now cannot be turned on, it keeps getting back to flash mode whenever I connect it to the computer.
Please help!
I am sorry but I only follow steps throughtout the flashing method, I don't know if I had to unlock my bootloader before I flash it, or root it.
Please help, I am currently researching now If I can turn back my phone again.
flash to stock rom.. .42 firmware is good if you want to keep root..i saw the image from that are you flashing any kernel..?beacause you are in fastboot mode..but to flash ftf file you have to be in flashmode
Error with the flashtool, phone stop working
No, I am not flashing any kernels. I was in flash mode. I was never in fastboot mode.
Ok thanks for the heads up, I'll use .42 instead.
But still currently having this problem. I can't do anything because I can't turn on the phone. If I turn it on, the logo doesn't come up and the blinking light is on GREEN, so that means I am still in flashmode (even without the connection to the computer). If I connect the phone when the flashtool is there, its says on the log that it's on flashmode.
The Big Problem is, How can I turn it on back to normal mode. releasing the flash mode. If that really is the problem, when the error came up.
Second Question. Do you have to unlock the bootloader to perform the root or flashtool. I already have installed the adb drivers.
first there is no need of unlock bootloader to flash ftf file..just download ftf file then put in firmware folder..then open flashtool... click on flash and then click on flashmod then just select your ftf file and press ok..switch off your mobile..then press volume down button and coonect your mobile to pc using usb cable..flashtool will flash that firmware...
Thanks...
But, I have already followed all those steps you said. then that error comes up (refer to the thumbnail above). After that I haven't been able to turn on the phone.
When I try to turn on the phone, the logo screen won't show and the light that blinks above the phone is green. Meaning its kinda stuck on flashmode.
I am so scared right now, if I can't fix it.

Can you explain with more detail about "connecting to flashmode in flashtool" ?
I read in some posts-connect your phone to flashtool and flash the stock firmware files to get back your phone
I connected my phone with the volume key down to flashtool,but it stated an error and didnt proceed..
You erased everything, obviousely. But Flashtool should still work.
I'll go searching for a user who I know already did the same as you... maybe he'll have useful information
EDIT
Which error?

Which sony logo, The first at boot or the boot animation one?
Are you able to boot your device in clockworkmmod?
Ok, let's do this:
-Start Flashtool
-Plug USB cable to PC
-Turn off the phone
-Press and hold volume down button
-Plug microUSB to the phone
-Post the complete Flashtool log
By the way, did you install flashmode drivers?

He formatted everything, CWM included.
I installed the flashmode drivers..
It gets stuck at the black sony logo at the start and does nothing,I had to switch it off after removing the battery..
When I connect the phone in flashmode,it says error and says device disconnected and then the phone remains at sony logo..
I'll post the log soon
GOOD NEWS!
I tried flashtool again and this time it WORKED!!
THANK YOU TO ALL
p.s-Now I'm on stock GB .58
Try to flash a different ftf file and see, preferentially an old GB Build.
If this doesn't work,
Try updating to latest Flashtool.
Install the exe at /flashtool/drivers folder.
Then flash again.
Thanks,
Rick
Edit: Okay, never mind. It's done.

[SOLVED] SK17i Downgrade 4.1.B.587 to 4.1.B.431

Hello, I want to downgrade my soft in sk17i from 4.1.B.587 to 4.1.B.431. How can i do this? I already downloaded the soft.. I know that there is a program called flashtool but im afraid that something bad can happen to my phone :| Can you help me?
Download flashtool and the 4.1.B.431.ftf firmware for the sk17i
Now you go in the flashtool installation folder -> drivers and you install all drivers for all devices/modes. Place the 4.1.B.431 firmware in flashtool -> firmwares and launch flashtool. Now click on the flash, select flashmode, select the ftf, but don't tick wipe data, otherwise all your data is lost. Now click okay, turn off your phone, wait a few seconds, hold volume down and while holding volume down connect your phone via usb to your pc. Flashtool will flash the firmware automatically and when flashtool has finished, unplug your phone and start it :good:

Totally Bricked: S1 Bootloader wrong. No flashmode/no fastboot/no boot only SOMC

Hello guys, today it's a really bad day for me. My M4 is now totally bricked.
Here's why:
I installed CM 12.1 and I will get back to stock, but my phone not enter in flashmode. So I flashed a zip file of stock rom but it not booted. I want to get Flashmode back, and I find a flashable zip that restore flashmode in Sony Xperia M. I flashed it and... bye bye M4. Now the phone only enter in SOMC FLASH DEVICE, Flashtool not flash, but say:
Device connected with USB debugging OFF. For 2011 devices line be sure that you aren't in MTP mode.
Sometimes enter in Unkown device. I have all drivers and I'm using original cable with USB 2.0 port. Now I'm trying to restore with PCC.
I removed the battery connectors for a while, put them back, but nothing changed.
My battery is at 100%.
What should I do?
So flash mode does not work anymore? This may seem inappropriate to say now that your phone is dead but if you have technical experience you could make a guide to opening and repairing the M4 or at least take pictures. But if flash mode or fastboot works try to restore it first
Well... Sorry to hear that :/ but uh..
http://forum.xda-developers.com/yureka/help/question-qualcomm-download-mode-k-t3068040
It uses a MSM8939 board same as ours. It's up to you if you want to attempt it but I'm suggesting not to.. Good luck anyway!
Thank you very much! Firstly I will try to send it to the shop where I buyd (sorry my english) and if they don't change the phone I will try this. Really thank you again!
EDIT: Ok, I am following the tutorial, but my M4 show only qhsusb_bulk with no driver. What I have to do?

probably you flashed custom kernel/rom with bootloader unlock=NO , you can try the S1 tool to restore your bootloader but you must have the original one.

Thanx for reply,
My bootloader status is yes.
I think wrong kernel makes this problem,
By the way, how s1 bootloader restore.
Any tools?
And how get original bootloader.
Is loader.sin is helpful from ftf?
Thank u.
I'm waiting for your reply

you must have qhsusb_dload detected if yes then download this zip extract it and run s1tool, you must copy boot.sin and s1boot from your stock rom, the two files inside the zip are not for your C3, but you can try at your own risk.

Xperia Z4 SGP771 wont turn on, wont boot, dead but with fastboot mode access

Hi guys, a friend asked me to repair her tablet Xperia Z4 SGP771, it does not boot at all.. It does have access to fastboot mode (blue light) and flash mode (green light).
This device had the bootloader unlocked and was rooted and, for some reason, she tried to factory reset it. It is dead since then...
I have no clue of which ROM version it had, or CDA, firmware.. location etc...
When I connected the device on PC (Win10) and try to verify connectivity via adb cmd the device list is empty, but when I tried to reboot into bootloader it was successful. (see pic1.jpg attached)
I tried to flash TWRP via fastboot but no success, see pic2.jpg, it says FAILED (remote: Command not allowed)
I verified connections via flashtool, it says: Device Status: FASTBOOT mode, see pic3.jpg, which seems to be working fine..
Now, I was thinking to download a generic FTF firmware using XperiFirm and then flash it via Flashtool, is there anything I should know before proceeding on this step? I will wait for any guide/light from you guys... thx in adv
Hi,
Flash any MM 6.01 firmware (32.2.A.5.11). No Nougat firmware.
Here is an old guide to flash a firmware but you can use it : http://www.xperiablog.net/2015/03/1...peria-lollipop-using-xperifirm-and-flashtool/
And upgrade FlashTool to 0.9.23.2

I tried that but it is failing in the middle of the process. See pic, any other idea?
get the LATEST version of flashtool
you also might try another FTF in case something is wrong with your download
check that the drivers for your operating system are properly installed an up to date (more on that in my [GUIDE])

after upgrading FlashTool to 0.9.23.2, I was able to flash the rom SGP771_Customized NOBA_1295-7869_32.2.A.5.11, the device is working fine now.
