Downgrade LP to KK doesn't work. Rooting not possible - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hello!
I have a problem with downgrading my Z3c from LP to KK. I followed this threat for rooting the device http:##tiny.cc#1qs2ay (- change # to /), but got stuck at #12. I am getting into a bootloop or some kind of rainbow-effect. I recorded it with my other phone -> https:##youtu.be#S7nHgrI2MJQ
I used all of this stock firmwares http:##tiny.c#dws2ay and wiped every time the apps and userdata. An upgrade to MM was possible.
My phone has no simlock and the bootloader is locked. I used the flashtool 0.9.20.0 and installed all drivers (OS Win10 - disabled driver signature enforcement):
Sony sa0111AdbDeviceClass - 04/15/2014
Sony Net - 05/05/2014 (Status not needed??)
Google inc WinUSB - 12/06/2010
ggsomc - 11/10/2014
What am I doing wrong?
Thanks for any help!:good:

I had the same issue it's simple : you may have forgotten to wipe everything in flashtool before launching the installation check the wipe boxes.

Hi!
You mean the checkboxes in the firmware selector? -> http:##tiny.cc#qix2ay.... These two boxes were always checked!

Z3 Compact have 2 models, D5833 and D5803 so you probarly flashed the wrong firmware. My model is D5803, dated 15W25 (Year: 15, Week: 25) and downgrade to Kitkat is working fine

The upgrade to MM with the firmware for D5803 worked and the model number in the menu "About phone" is D5803. See the attached file. Is it possible to somehow format everything and than install a new firmware?

the flashtool does wipe everything when you flash a firmware. it does not replace withouy wipe. try dowbgrade to LP, root with Kingroot and flash custom recovery in your phone to flash pre-rooted firmwares

Which firmware to flash?

Hi all,
I have a T710 running 5.0.2 which I have rooted and installed TWRP and realize now that I won't receive the OTA update (if there ever is one) for my device.
My question is about the downloadable firmware on the Sammobile site. There is no 5.1.1 available for my country (UK) but there is a new one (Nov 1st) its country is "Unknown".
Would it be risky to flash this? And if not would it be easy enough to re-root and install TWRP?
I have made a backup in TWRP which I have on my SD card but I'm worried that if I attempt to flash this new firmware and something goes wrong then i might not be able to install the backup if TWRP is wiped.
Thanks in advance.
I've been using the Canadian 5.1.1 for a while on my T710 nordic. Runs great... No problems whatsoever ☺

Of course you can flash your backup, just reinstall twrp.
Ok , cheers guys
A little late to the party, but I flashed 5.1.1_T710XXU1BOH7_T710XAR1BOH7_XAR from the stock collection thread last night on my UK tab S2 T710 (like yours originally 5.0.2 rooted) and thus far it's running fine.

Updating is easy and if Sony PC Companion is malfunctioning, you could use Flashtool ( get it here )
After that you can download the latest firmware ( ftf format ) here
There are some guides on how to flash the latest firmware, and don't worry flashing won't void your warranty or root your device.
This is the best and the most informative click me
Good luck
Hi
If I do that, will ota updates work in future?
Don't have time to fiddle around too much now and again every time there's an update,
Any ideas how to get it to pick up the ota update, which I'm sure has already been released for its region?
There's a thread around here with a tool to download the official full firmware files per region and flash them to your phone.
As long as you use a region that's compatible (with radios and all) the effect should be a perfectly fresh installed stock phone that will pick up OTA's just like any other official firmware.
sony flashtool or something? I can't remember.
Hi,
The firmware thats on the phone is global region,
23.0.A.2.93 - Unbranded - GLOBAL (1286-9917) #1
But i dont see lollipop updates for it.
Which region firmware should i use to flash?? Which would work 100%
Pls help with some advise asap which will work

New Xperia Z3+ won't auto update to 7.x

I just got a new Z3+ to replace my old one that got broken. The new one had Android 6.0.0 and immediately updated to 6.0.1 32.2.A.0.253. But now it says my system is up-to-date and doesn't show nougat available. I went to the Sony support website (https://support.sonymobile.com/us/software/#gref) and entered the IMEI and it also says "Your Xperia Z3+ is up-to-date release 32.2.A.0.253". Right under that, it has a block that says "My Android Information" and it says Android 7.1 Nougat is released for Xperia Z3+. (See attached image)
So, I'm confused. Do I need to give it more time and maybe it will show the OTA update available?
I don't seem to be able to restore my Google backup from the old phone while the Android versions are mismatched.

For your region it may not released. You can flash Naugat update of any region through Flashtool, but you have read and understand the process and need to do the experiment (no need to unlock bootloader). I have flashed different versions (upgrade or downgrade) using flashtool number of times.
Check this link for more information and step by step guide. Do all your experiments at your own risk

Do you mean a region associated with the phone, or the carrier (T-mobile)? My old phone is a Z3+ and it updated to Nougat automatically. If there's a region associated with the phone, is there a way to see that?
If it is Carrier locked, then carrier specific else region specific update to be released. If your phone is locked with T-Mobile, don't try to use flashtool. I not aware of carrier locked phones flashing.

Then it should be updated to Naugat. Check in Xperia Firmware once : Link

I went ahead and flashed it manually via FlashTool and all is good now. Once it was updated, it saw my Google backup and I was able to restore it. Thanks for the help.

downgrade?

Hi guys
Someone has succeeded with downgrade from oreo to nougat ? I need go to huawei service, to exchange the display, but problem is "relocked bootloader"
So many tutorials here, which to follow for downgrade and have "locked bootloader" ?
You can use HiSuite or install the downgrade firmware through Firmware Finder. It has the normal Nougat version, but in the description it tells that it downgrades.
HiSuite tells me that I have the latest version so.. I cant downgrade from HiSuite, or if i can tell me how to do it please
@yungshadow
As M1chiel said, try with Firmware Finder.
Remember!! Everything is on your own risk!!
Don't know which version you have, but for me this is the roll back firmware...
Let's try. But.. still 0%
If you use proxy option, you have to set proxy in WiFi settings.
localhost and 8080
Then start download and wait until 4-5%, then disable proxy and continue download.
i'm using DNS. Now 11% XD
ok i'm finally have emui 5. Now i must rebrand ?
That I don't know, I already didn't understand why you wanted to downgrade ??

I need to have bootloader status "locked" not "relocked" so i must rebrand to l09 and back to l29 yeah?
Ok guys
I Found a solution.
1. Downgrade from Oreo via FF using B185 (downgrade firmware) thanks
djg269 said:
2. Download some L09 firmware and install via FF
3. After installing I had bootloop (huawei logo, booting system for 10-15 sec and still restarting)
4. Enter eRecovery VOL-UP + POWER > Wipe data and cache
5. After Wipe phone said it's still L29 but now bootloader is locked not relocked
So i'm done now

Glad you got it fixed!!
Sent from my VTR-L09 using XDA Labs
I have a small question - in FF it says to make sure my current version is not "unlocked" - does that mean the bootloader or...? I just want to downgrade to B180 so I can install HuShed. I'm on L29C432B360 currently.
I don't remember this information. Could u send here Screenshoot with that dialog from FF ?
Same screenshot as post #4 -> https://forum.xda-developers.com/showpost.php?p=76556011&postcount=4
I used b185 from b360 with unlocked bootloader and I had no problems.
You should use b185(rollback firmware) and after this will be able toinstall whatever you want
Alright, last question - I have TWRP installed for 8.0. Will this affect the downgrade somehow? Because for example I can't install OTAs with TWRP. I'm sorry I'm kinda new to these kinds of stuff.
I didn't have installed twrp for 8.0 when i Decided to do downgrade so I think it doesn't matter but you can flash stock recovery for 8.0 if u want ofc.
Now i'm on 8.0.0.365(c432) but with official OTA update

Firmware updates

Hi guys, i was wondering if Sony releases updates in different regions at different times ?
I read in another thread that the Oktober release was already available ?
If so can i use a VPN client to get my update quicker ?
Still on the august update here.
Yes, depending on your region (and if dual sim or single sim), updates are released at different times.
You can, however manually update by downloading the firmware using Xperifirm, and manually update using newflasher. The flashtool software hasn't been updated yet for the XZ3.

I have downloaded the correct firmware (unbranded UK) for my phone model.
Does newflasher work with the XZ3 ? I also tried Flashtool64 but this software is not updated for the XZ3 yet, it does download the firmware but when selecting flash no packages are shown.
So i am a bit stuck.

You can download another firmware for your device model using Xperifirm and flash it using NewFlasher. While flashing you need to exclude the files ending with .ta extension.
There is a tutorial available for Newflasher.

DO NOT exclude ta files. This is bad advice for newer Sony devices.
Only exclude userdata sin file if want to keep own files
