Hi guys , need some information, I was just wondering is it possible that I could downgrade back to ics after putting jellybean on my phone?
Your help is appreciated.
All the best
Chris.

Yes it is.
How did you upgrade?
If you upgraded via FlashTool you can just as easily downgrade using the same method, just by using an ICS .TFT instead of the JB one.
Any reason why you want to downgrade?
Make sure you do a complete wipe to make the ROM to be good and dandy, and the battery will get better after a few days.
Sure you can, you just need to flash ics ROM with flashtool (you dont need to have unlocked bootloader)
But I dont see the reason to downgrade

Thanks for the replies, I want to go back to ICS due to the major battery drain that I am getting, I have read a few threads now on here and also esato and jellybean battery seems to be very hit and miss.
I live how fast the phone has become but can't live with a poor battery. Got any ideas before I go back to ICS?

Yes wait a few days, the first few days I'd flashing a Rom are always battery heavy

ok well , i have just read that formatting to extenal and internal memory helps , so i have just done that .
as you say its a big upgrade firmware wise so going to give it a couple of days and then look at what the diffrence is again .
Ok so reporting back on my T's jellybean upgrade, seems that it's starting to level out a lot now, as I said in my last post did the memory thing and formatted both And the phone has responded very very well.
Seems to get a whole days usage now and maybe a bit more. I always charge anyways over night so nothing to worry about. How's yours?

i had the same dilema as you to downgrade to 4.0.4...
I noticed today that the phone drains 4 to 8 % battery in standby mode over the night.. i havent noticed something like this in 4.0.4 .
I think the battery management was better.
Anyway i will follow your suggestion to wait a few days to level the situation .
I updated with mac bridge . What is the best method if i decide to downgrade ?
I need a clean install method .Format everything and clean install the rom i decide to install.
Also does the repair option in pc companion or bridge does a clean install;
Thank you

Yes.
thank you so much for your quick reply!
so if i got it right the repair option performs a clean install to the existing rom ..In my case it will reinstall JB 4.1.2
If i choose the flash tool i will choose the rom i want .. So do i get it right?
And if so where can i download the original 4.0.4 rom ? thank you again for your help!

Look in the All in one thread. Its the first thread in the Q&A section and has all available ftf files in post 3.
Yep use the original generic UK tft there on the forum mate there is a whole list of them, use flashtool and you'll have no problems.
In addition to that I downgraded my via flashtool and used pc companion to upgrade to jellybean if that helps also at the same time formatted the memory external and internal and once the upgrade was done wiped all data and set up, I've gone a full 20 Hours now and have 40% left which seems like it's done the trick.
Good luck mate.

no luck with repair option.... It restores 4.1.2 and not the factory rom ..which in my case was 4.0.4 or 4.0.1..
So i will download the generic uk 4.0.4 rom and flash it with flash tool ..and thats it ? no other actions required ?

I also going to use flashtool 0.9.10.1 for mac.
Is it better if i use the official sony flash tool EMA ?
In my opinion the Jelly bean update is more of a downgrade then any thing it's very buggy and has a dated looking ui and the new features have been used before on other manufacturers phones like Motorola the lock screen is gay as **** and the camera is now a 12 megapixel instead of a 13 and the keyboard seems to be the same with no new JB features.
Sent from my LT30p using xda premium
Yeah mate that's exactly it, using that firmware and flashtool you should have no problems at all.
I'm going to carry on playing with jellybean for a couple more days and then reevaluate which firmware I would prefer to be on.
Hope that all goes well for you anyways.

If pccompanion restores 4.1.2 that is now the factory Rom. It's the latest official Rom for your phone provided by Sony.
If you really want the Rom you had before the official upgrade you have now, then use any file explorer and open the build.prop file that is found in the system folder.
Find the line that starts ro.version.customisation. And then had 8 numbers after it, tell me what those numbers are and I can point you in the right direction
Anyway, you can't use Emma to flash that, you must use flash tool

Also if possible, can u give feedback on how smooth it works. Thnx. I personally own a samsung phone so im more familiar with ODIN.

Was wondering if there were any easy to install tweaks for the xperia T jellybean os, that I can flash with cwm
That would allow me to customize many appearence features on statusbar, and threw out the phone? Would need something that will work on a locked bootloader! Maybe even recomendations on a feature packed custom ROM that uses a stock kernal? Thanks.
Sent from my LT30p using xda app-developers app
No
There are no tweak packs, there is a slight custom ROM, stock based so works on locked bootloaders, XperimenT, its in the android development section, its ICS based, a JB version is being worked on
Thanks! Im using Xperiment beta 2. I love how fast the phone runs, and how good my battery is! I just dont see anything different other than the boot screen . Maybe because its a beta?

Yeah it's because it's a beta and the dev wants to get it stable before he adds customizations, also they don't work from ICS so new ways are needed to get it working. Patience

Fair enough! I might flash the xperimenT ics stable then, quick question tho.. Can I not keep the jb xperimenT backup on my phone, and then swap roms as needed via cwm restore? Would be fairly cool. On the same note, minus the odd crash here and there, the experimenT jb beta is just incredible performance wise.

You may have issues as to swap versions, JB and ICS, a lot of the time you need format sd card, you'll also need to make sure the correct kernel is in place and that you flash the correct cwm+reboot fix, so it is a pain bit doable

I'm an advocate for the best rom, so:
Don't use ICS... simple as that... It uses way too much memory, and although the rom is FASTER than any GB rom, it scores close to 2800-2900 in Antutu, compared to 2500-2600 for stock GB, the speed advantage dissapears very fast when the RAM is full (usually you work with 100 -90 MB) and the constant swapping makes the device unusable... you could get away for some time by using a cleaned (custom) rom, but... it's more of the same actually!
I tried custom kernels, some custom roms, but are all the same, recovery is a pain in the ass to get it installed so... yeah... don't use it or wait for 30D, maybe it's better!
As you are new to the device, my advice is better grounded by the fact that ICS is more strict security wise and you could get a brick in more ways than GB, if you update to stock ICS, and install a recovery, you get a brick and so on... try to know the device or read very very well before flashing a ICS rom, or better use only nandroid backups that you flash from your custom recovery...

You can try this. Do a factory reset , flash cocore kernel , root you phone and install Lagfix app from playstore. I do it all with my phone and it work!
Or youcan try other firmware , India firmware is a good firmware to try

Try the Indian firmware. Warranty stays if you use official Samsung signed firmwares.
Also, go to developer options, scroll to the very bottom and limit background processes to 2.

Unroot is done simply by flashing stock FW again, and voila - no root. So he do not need to affraid of that.
I'm having the same issue with the Polish firmware. Jelly Bean was advertised as being faster and smoother but after updating from 2.3.6 to 4.1.2 via Kies my phone became really laggy (menu animations are choppy as hell, some apps like the phone one take up to 3 seconds to start up) and occasionally there are some really annoying lock-ups where the phone becomes completely unresponsive for 1-2 min. I tried doing a factory reset but that didn't do much. Overall I'm really disappointed with the official 4.1.2 update. Will rooting my phone and installing a custom core like CoCore help in a noticeable way?

Yes,imo after installing CoCore,there will be a definite lag reduction. Much smoother.Dialer may still take time to open though.. for that you can use third party apps like exdialer which is much faster..

Hi all I upgraded my phone to Jellybean. I cleared all the data and cache after updating via Recovery. But the phone is laggy as hell. It just freezes if you open more than application. Screen becomes unresponsive. The apps that I have moved to SD card disappear from homescreen if you reatart the phone. Really very annoyed with the update. Gingerbread was butter smooth. Now I want your opinion. Should I go back to GB or should root it and install a custom kernel? Please help.

fyi do not use ''Swap Memory Mod'' and factory reset. agreed with you 4.1.2 is laggy but it can be fixed.:silly:
I recently updated my Samsung Galaxy S Advance with JB 4.1.2 through Samsung KIES software. Earlier my phone wasn't lagging with the Android GB version, and I was able to play games without any lag. After updating it to JB 4.1.2, I'm experiencing lagging when I play games or browse internet.
I haven't updated any ROM, I purchased a new phone, connected the phone to KIES using USB cable. As soon as this connection was successful, it should me a notification that a new Android version(JB) is available, hence I updated it.
Please provide me some solutions so that I can remove this lag.
Enter recovery mode. Factory reset, wipe cache.
Root, custom kernel and remove bloatware. Thats all you can do on stock to feel better.

Any method is the same cause in the end you'll still need to do factory reset as updating from gb to jb is a major update. Xxlqe and ddulp8 seems good.

Does anybody have any other method? Downloading custom kernel will void my warranty, so I don't wanna do it.
Does reverting back to GingerBread is the only option?

You don't have to worry about warranty because rooting and flashing custom roms/kernel for jb is hassle free and does not trigger your binary count. So, that means when you want to claim your warranty, just flash back your country official firmware and you get back your warranty. As long as you do everything right and you don't lose your download mode (means you don't brick your device) you have nothing to worry about regarding the warranty.
You can also revert back to gb if you want but I prefer to stay with jb for the apps I use. It's not a massive lag for me. Just slight delay when opening dialer, contacts and camera but the rest is awesome.

Here, you can follow this guide here. Make sure you read everything and do exactly as it says.
It is recommended that you back up your imei. Follow this guide here.
For stock based, many users said that LightJB is great. You can try that but I prefer to use Pure Vanilla because of the looks. You can also try cm-based roms although it's still in beta phase. Look in the original android development section.
Edit: Btw, which version you have? I9070 or I9070P? Make sure to check that first before flashing anything. You can see that at start up and also at about phone in settings.
