Hot to downgrade my mini pro sk17i from ICS 4.0.4 to GB 2.3.4

Hi experts,
Purely i'm new to this blog and also the android platform. I don't even know about unlocking bootloader and all that stuff (just heard my friends saying). I have an xperia mini pro sk17i and was having GB 2.3.4 at the time of purchasing.Now when official update for ICS 4.0.4 had came,i updated without knowing that it will affect my xperia's performance.Now i started getting lags in games which was very smothly running in previous OS (GB). I would like to switch back to GB and want to root ( also from my friends conversation) the GB.
I need a complete guide for this because i should not end in a brick state,whether to do an unlock bootloader, or flash it, which tools to use and all.... Kindly help me guys.......

Maybe this is Stock but it is 2.3.4 and is stable but you have to unlock bootloader

You need not unlock the bootloader to downgrade. Just use flashtool and get your GB ROM. Have a look at here http://mytechencounters.wordpress.com/2012/03/17/root-your-xperia-phone-without-voiding-warranty

Rooting? Stability? Unlocked Bootloader still possible?

I have a few questions...
I've been around xda for a bit rooting and flashing roms but this TF300 business sounds a bit more complicated so I have some questions.
Build# JOP40D.WW_epad-10.6.1.8-20130225
I have a TF300T running stock 4.2.1 rooted with a bunch of root mods to make things a bit smoother but it looks like custom rom would be still faster than this. Am I correct?
How stable are the custom roms in comparison to the stock rom? Will I be able to get OTA updates in the future if ASUS decides to release more?
Is my bootloader still unlockable if I'm running whatever came with the last stock update?
How hard it is to brick a TF300? I've had 3 phones that were pretty much unbrickable. (Assuming one does not flash the wrong files to the wrong phone)
Which tutorial should I be follow? Can I unlock the bootloader on 4.2.1's bootloader or do I have to downgrade?

Is this sub-forum not friendly enough to help out a new guy who has read through many topics to try and help himself first?

how did you unlock your bootloader may i ask?

I did it before the update then used one on here that didn't lock it

All that is available are AOSP ROMs or CM11. No one has been able to get the new kitkat kernel to boot with our old firmware. :crying:
At this point, I'm happy with DU weekly builds. Don't really miss Touchwiz, I do flash MOAR sometimes. However, I still things run much better on vanilla android.

While that is correct there are several decent versions of aosp and other variations. I would seriously look around for what's available but stay away from anything that says BL LOCKED or any variation of that
From my S3 on Wicked 4.3

I've been having recurring camera reboots on my stock, rooted, BL-unlocked ROM and really want to get away from that. Does either CM or any of the crop of AOSP ROMs of 4.4 for similarly unlocked devices manage to work well w/ phone hardware (e.g., cameras work properly, mic works properly, bluetooth works properly) without being too "1337 g4m3r XT3M3!!!"? I'd like a fairly simple layout, to be honest, without a bunch of crufty, automatic extra features. Just a plain, 4.4.4 ROM that actually lets me take more than one picture before rebooting

Nope. I believe you have to pay $50 to jtag your device back to an unlocked bootloader. I maybe wrong, but i believe that is the only hope. For the time being, the only unlockable devices seem to be HTC.

No, my phone's currently on the unlocked 4.3 build floating around the forums; i was wondering which of the unlocked 4.4 builds (e.g., AOSP, Cyanogenmod) was most stable, since there isn't a TW build compatible with my unlocked bootloader.

Questions and Help issues belong in Q&A, Help and Troubleshooting...not Original Development
All the development sections are only for developers to post work
As for looking for the "best" or "most stable" ROMs it is strongly advised that you read the development threads yourself
Find out what bugs and fixes are offered in the thread and if that appeals to you, or has a bug YOU can live with
No one can pick your ROM for you nor should they...in the end only YOU know what it is best for YOU.
As a general tip, stay away from Nightlies if you want stability as new fixes and bugs are presented often in those.

Custom ROM's for Z3?

Hi there,
I know this May be a silly question but my iPhone 5s is getting on my last nerves and this is the only thing holding me back from ordering a Z3 today. Does anyone have any idea when the first custom roms will be out for the z3? I can't stand skinned androids (although I've never owned a Sony handset before).. I just wouldn't want to buy one and having to wait a few months for CM/PA.
Thanks for anyone who replies!

Mate what's wrong wid or iPhone by the way. One of the best phones on the market. Anyways about custom ROMs or PA/CM ROMs might come by end of Oct or Nov. No one knows but they are surely in the pipeline although I love the xperia UI which is close to stock android and the best among other OEM skins. I have come on an xperia from an iPhone. Trust me xperia is the only one phone where u would enjoy the touch sensitivity like the iPhone.

I love the iphones when they are jailbreakable but for the next forseeable months I can't see an ios 8 JB being released... I love the freedom on Android and constantly find myself going back to iPhone due to the lack of a decent camera found on any Android handsets (I've owned HTC One, S5, Note 3, S4, Nexus 5)..

You can't find a decent camera on any Android phone?
And you go to an iPhone for their cameras? Rly? Hahahaha hahaha you're funny.

Why are there almost no custom roms for this phone. The Android development section has 11 posts?
Other phones have thousands. Why is that.
I was thinking to buy one of these, but this sets me off.
Is there a root , that doen´t void warranty ?
thx

No there is no Lock Bootloader with root atm. I would guess once that is solved there will be more custom roms.

Most custom roms (CM MIUM AOKP AOSP PAC) etc require an unlocked bootloader as well as root. Unlocking the boot voids warrenty, hence the disclaimer in the OP of all their ROMS.
Root with a locked bootloader will only lead to custom roms based on stock firmware. they have more customisation than stock, but not as much as true custom roms based on another kernel.

Ok, thanks. Still , although the warranty is lost. There is still so little activity. Why is that. I just read the news, that Sony release AOSP Versions for all phones and allows the bootloaders to be unlocked. I thought that this would be a developers dream, for CM for example.
So, whats wrong with the phone. I still dont get it.

Was considering z3 went with g3 as there seems like way more dev support for LG phone and tons of LP roms in alpha beta stage.
Whats up with sony?

No one want to root because of loss of DRM keys..

And what does that mean?
thx

I'm not sure if it's a good idea to resurrect a old thread (zombies!)
but i see there are almost no custom roms for Z3 (either stock based or AOSP or something else)
the stock based are still on Kitkat.. (1 Rom)
AOSP i see only Cyanogen but with very little development (of course a pair of roms based on CM).
The freexperia project is almost non functional.
I'm not demoting the devs / modders... just not finding the root cause of this.
The Very old Samsung S3 is still getting too much love than our new phone, that has qualcomm SOC and thus, unlimited (sort of) open source development
Something is wrong with this phone or i'm missing something?

Im waiting too..

Stock is good enough.

I know stock is great. Just wonder if a modified custom ROM could squeeze the battery further. I doubt it but u never know.

It could happen, that is true, I'm sure soon Z3 will have some custom ROM's for users to play with, on it.

[Q] Question about going from 4.4 ROM to 4.1.2 Stock (Not a BL question).

I recently swapped out my S3 using asurion (put it completely back to 4.0.4 stock and everything checked out) and the replacement came with 4.1.2 (so thankful :good.
I've already rooted my phone to get my wireless tether back and am looking through a few ROMs.
My question is:
I remember when looking at kitkat roms before I cracked the screen on my old one, it talked alot about repartitioning being necessary during the flash. If I upgrade to a 4.4.x ROM would it still be possible to ODIN back to 4.0.4/4.1.2 if I decide I don't like the new ROM or if I have to send the phone in?
I'm talking about a custom 4.4.x ROM not the stock/Locked BL 4.4.
I did a search and most of the results were for people who had locked BL. I do not :highfive:
Also if anybody wants to weigh in on ROMs I'm all ears.
I haven't found any TW Kitkat roms that I liked, so I was looking at CM11 /AOSP roms.
Thanks!

As long as you don't take any of the locked bootloader roms aka the the new TW 4.4.2 rom or any BL roms you should be ok to go backwards.
