hi
i know a lot of people do not like the new 4.2.2. i myself hate it. so i want to downgrade my sgp312 xperia tablet z wifi 32gb bought from saturn germany.
i have a few questions:
1.obviously i need to downgrade using flash tool. should i use the latest version v0.9.11.0 or should i use flashtool-0.9.10.2beta4-windows.exe ?
2.will my bootloader be unlocked in the process?
3.if i take my device for warranty in the future, will sony technicians see something and i lose my warranty of the device?
4.will downgrading break bravia or other sony technology that breaks when rooting/unlocking
5.what stock fw should i use for my german xtz ? is this one here good? http://forum.xda-developers.com/showthread.php?t=2344577
6.unfortunately i cannot remember what fw i was on before the official upgrade. i know for sure i was on the latest. maybe someone here knows what the latest was for my tab. is there anybody that can give me the exact fw code that was before i put the 4.2.2?
7.should i follow the tutorial here: http://forum.xda-developers.com/showthread.php?t=2240614 to the letter? does it work for my tab also?
thanks and sorry if any of the questions are noob!

i'm just posting to say that i'm hoping somebody answers you, because i hate the upgrade as well. it's not an upgrade. sony took their nice, well thought out UI enhancements (pretty much a first for an OEM in the post-gingerbread world), got rid of half of them, then ruined the others.
i am seriously disappointed in the hack job they did. sony did such a nice job with their skin on 4.1.2, why on earth did they need to ruin it? Their notification center was better than googles new one, especially for a tablet!
ugh.

1 - They should both work, I flashed mine with an older version without issues.
2 - Flashing your device with an FTF will NOT affect your bootloader status, in other words...No your bootloader will remain locked.
3 - Flashing an FTF is a Sony original firmware so no your warranty will not be voided, although I wouldn't declare that you flashed it with Flashtool. Unlocking your bootloader will void your warranty. There are ways to relock it but I don't know if they will be able to tell.
4 - No, downgrading doesn't break anything. Unlocking your bootloader will break Bravia engine so in order to restore Bravia you need to backup your TA before unlocking it.
5 - I was using build 370 so as long as you use the one for your device, you will be fine. (SGP312, WiFi Only)
6 - From what I know, the WiFi model only had build 370 on 4.1.2 and now build 136 for 4.2.2
7 - Yes, that is a good tutorial for using Flashtool, they are using it to flash an Xperia phone but the same applies for the tablet, just select the appropriate file when flashing obviously.
Good Luck! :highfive:
Hi,
I've seen a few threads here about flashing unbranded firmware, I have a Telstra branded (Australian) Z5C . I want to know if I can use the flashtool to flash an unbranded firmware WITHOUT unlocking my bootloader or voiding my warranty in any way. Can someone confirm that I can do this?
Long story short I don't want to wait for Telstra to "optimise" Marshmallow for 6 months before I get the update. I would like to be able to get it as soon as sony releases it.
Any help appreciated, Cheers.
You don't need an unlocked bootloader to flash an official firmware. Plus, if you want warranty, you can flash back the telstra firmware when needed
My wife and I both have Samsung SGH-i337 S4 unlocked (not rooted) AT&T phones running 5.0.1 with KNOX ver 2.3, baseband ver i337ucugok2. We would both like to abandon 5.0.1 and go back to 4.4.4. A cell phone repair shop I frequent advised me that these phones cannot be downgraded to 4.4.4 because of the KNOX security. I've examined many threads on this site and others and cannot find precise discussion about the presence of KNOX and if or how it may thwart our desires to downgrade. Nor can I find precise discussion as to whether rooting the phones first is necessary.
Can I, in fact, downgrade the OS on these particular phones?
If so, do I need to root the phones first?
Is rooting required in order to prevent an OTA upgrade back to 5?
Or does KNOX knock me out of the box entirely?
Responses or pointers to the appropriate threads would be most appreciated.
same question ,
cant downgrade?
i dont know if its help:

Hi everyone,
I want to buy an Xperia X. The version I would buy (F5121) is branded by an Italian carrier (TIM). Could I install an unbranded stock rom on it ? Do I need do unlock the bootloader or something, voiding the warranty? I'm asking because I would like to receive software updates as soon as possible.
Thanks everyone.
You can use flashtool to flash any stock rom you want. No need to unlock bootloader so you wont void warranty

In case of problems in the future, could I bring the device directly to sony with the unbranded firmware (FULL STOCK, NO ROOT AND LOCKED BOOTLOADER) or do I have to revert it to the original stock branded firmware? I'm afraid that thay could maybe refuse my warranty.
Thanks

the last time I returned a sony phone I relocked the bootloader and flashed a stock ftf. It was no problem. Dont think it matters if its branded or not
I have a S9+ G965F and I get the following error when trying to flash with Odin "sw rev check fail (bootloader) device: 9, binary: 2"
What is the problem? Would immensely appreciate help...
You are flashing binary 2 firmware on device which has binary 9.
You need to flash binary 9 firmware like G965FXXS9DTD7
Flash this Firmware

Downgrade to android 8; not android 10
It sure worked, but... I am still on android 10... I was going to downgrade to android 8.
I got my firmware from SamMobile, but apparently it is binary 2? Where can I find the firmware for android 8? (Did not understand how to find android versions in androidfilehost)
Edit: I followed this tutorial on YouTube: "Downgrade Android 10 Roll Back To Android 9 On All Samsung Galaxy Phones S9+/S9/S10+/S10e/Note10" by Android Doctor
In order to find your bootloader version you need to look at the 5th digit from the right, in the baseband in software version and you can easily find your android versions on sammobile, when you do get the current firmware you can also see listed the older firmwares

Why can't one downgrade when you have the firmware? (I am a total noob when it comes to this side of android)

I'm pretty sure Samsung prevents downgrading by blowing an e-fuse which prevents downgrading. I think they did this so that people cannot use special firmwares (without tripping knox) to remove FRP locks.

Has anyone figured out how to downgrade from 10 to 9 yet? I've tried a couple of tutorials, but they either not using and S10e but an older model WITHOUT Samsung bootloader locking, or they've been rooted - which I'd prefer to avoid.
I run into the error: "CHECK FAIL(BOOTLOADER) DEVICE: 7 BINARY: 3"
Then beneath this: "Pit_flash_binary - UNSUPPORTED VERSION".
Surely there MUST be a way to do this...?

That means you are trying to flash older binary into your phone which is already in newer binary (bootloader). Meaning that no, you can't flash older firmware into a newer one.

... Which means the e-fuse is something new since Android 8 or 9, as I've downgraded previously without this problem.
Would my only option now be to root, then or is there some way to downgrade the bootloader...?

I mean you can technically downgrade as long as the bootloader versions are the same.
Just as an example, if you are on Pie U3 bootloader, you can downgrade to Oreo U3 bootloader as well. You wouldn't be able to downgrade if you were already on Pie U4 bootloader and wanted to downgrande to Oreo U3 bootloader.

Well, it's the bootloader for this accursed Android 10, so I assume this will make downgrading impossible, dammit. ?
Ok. Next Q; can I assume the only way I can downgrade the bootloader is by rooting the phone...?
(It's just rebooted by the way. I don't *think* Knox has been tripped, as the version info is all there and nothing indicating otherwise.)

I'm not sure if there's a way to do it with or without root to be honest, I've never had the need to research anything regarding downgrading the bootloader. Hope you find what you're looking for.

Only just seen this reply, my friend.
I've decided I'm gonna try the Magisk root method created by @topjohnwu and see how this works out.
I've now switched to using a Huawei P30 Pro (New Edition) as my main phone, so I can afford to risk rooting the S10e and seeing if I can downgrade it like this, as it seems a fairly safe way to go for a Root Noob.
I dunno if rooting will let me downgrade the bootloader; I'm just assuming it will, as I'll have root level access to the device.
... And If it all goes south, then not too much'll be lost, I hope - plus I'll have learned something new, I suppose...
