[Q] Downgrade to 2.3.3?

Not rooted yet, but my phone is 2.3.4. I read on the rooting guide that it only works if your on 2.3.3 How would I do this?

Look in the dev section attn1 posted how to downgrade from 234 to 233. It works I used that guide to root my gfs phone last week

And a follow-up question: What are the significant differences between 2.3.3 and 2.3.4? Is it simply that 2.3.4 closes the exploit that allows S-off and root? Or are there other feature, stability or performance differences?
I got my Dinc2 Tuesday and never had the opportunity to test 2.3.3 before the phone upgraded itself. I'm not new to rooting/flashing, but am coming from an Eris where 1-click rooting meant the discussions were more focused on ROMs rather than on being locked out of root.
Thx,

I did not notice anything different between 2.3.3 and 2.3.4. I think the major changes were in how the phone communication with VZW network.

[Q] Difference between .42 .48 and .62?

So, my R800i came with .42 installed, my question to you guys, what are the differences between .42 .48 and .62?
From my past experience, the latest isn't always the best so that's why i'm asking you: Which one is better?

I found some differences

[Q] GB vs GB root vs ICS

Hello,
Had a quick question for anyone willing to give me a bit of feedback. I've been thinking about rooting my Xperia Play. I'm hesitant only because I don't want to get it if the functionality of ICS will be much of an improvement, if at all.
Should I stay with Gingerbread and wait to upgrade to Ice Cream Sandwich or should I root now and wait till the root for ICS is available in the future? I've been reading the forums here and found plenty of people trying the Beta ICS and it seems like it depends on the person whether they are fond of it or not. I'm certainly not wanting to Beta test ICS.
I'm looking for a kick in the right direction. I mean, I know I can unroot the phone if necessary I've seen forums about such, but it seems like an ordeal to root and then just to undo the root and I can tend to be a bit lazy. So should I stick with plain Gingerbread, wait to upgrade to ICS, or go and root my phone for the boost now in terms of power?
I use my Xperia Play as a phone, emulator, music player, and for general apps. Basically, just general recreation and it can certainly feel slow when just pulling up my texts on my phone. Let me know what you think is best.

Why would you need to unroot to upgrade to ICS? Just root now and upgrade when ICS is stable

An ordeal to root? The rooting methods are 1-click, it couldn't be easier

Exactly bro! Root on gb will beunrooted if you upgrade to ics. I thnk you mess up infos about rooting and unlocking bootloader.

Asking too many questions. If you wanted it, you would know you want it and you would have done it by now.
Stick with what you have. Wait for the official update. It'll be along soon I am sure

If you use DoomKernel with either the Official Sony Beta ICS or KA12 ICS beta roms you have Root.... if you flash KA12 it auto roots on install.....just FYI

Don't think one click rooting methods are available if he is on the latest firmware..
correct me, if im wrong..

Gonna comment to the OP's question about the speed difference as someone who has now tried (1) the standard GB rom (on verizon, so 2.3.3), (2) a super-fast GB replacement (Cola), (3) the Sony stock ICS beta, as well as (4) a custom rom based on the ICS beta....
IMO aside from a couple of very specific cases (email on GB releases really slowing the phone down when connected to Exchange ActiveSync, for one), no version of ICS will ever be able to match the speed of GB on this phone. I'm sure that some custom ICS roms will be great, but a custom GB rom built for speed will still be able to win in the end.

I could not help but upgrade to ICS lol, My boot loader has been unlocked since the day I bought it but when the Beta was released and they made progress on it (WiFi, and stuff) I just could not help myself , Once you remove bloatware its really stable and smooth.

[Q] LT15a Running LT15i - ICS 4.0.4 Update

I have my Xperia Arc (LT15a Rogers) running the LT15i Generic World (4.0.2.A.0.62) ROM, and with the imminent update to ICS 4.0.4 soon, I'm wondering how the update will work for my device.
Will running a different ROM from what it originally came with (Rogers-branded LT15a) affect my updating process? Or is it all dependent on the SI number under the battery? Also, is the update supposed to be OTA, or available through SEUS or something?

Can someone please help me? =S

Your phone only checks for updates for the version currently running on your phone. That aside, why would you wait for Rogers to release it when it likely won't be directly root-able (and since I assume you have a carrier-branded device, you can't unlock your bootloader except through the paid method to root) and won't be out for weeks.
The LT15a generic America ROM was released a few days ago, bloat-free and root-able. Use that.
(On a separate note, OTA is only for incremental updates. i.e. 2.x.x to 2.x.y, 2.k.m to 2.k.n, 4.0.w to 4.0.v, etc. Major updates between versions must be done through PC Companion.)

[Q] Root with GB update after 11/2011

Hello Community,
I've got my Xperia Play from a friend, so I can't tell for sure but I guess it was updated to GB 2.3.x after November 2011. (Assuming Xperia Play runs on Ginger Bread by default, sorry if I'm wrong)
Well, my aim is to root my Xperia Play. I tried it with the Easy Root Kit from DoomLord, unfortunately without success.
Then i noticed the major warning, that the method won't work for ICS or any phone upgraded to GB 2.3.x after 11/2011.
So i guess that's my problem.
After further investigating, i think the solution might be to flash an older GB version onto my phone, then using DoomLord kit and after that updating OTA, to keep root.
Well I'm really new to this, so I'm not sure if this is the best way (or if this way is even a solution) so I wanted to ask that and what version I should flash to, in order to use DoomLords kit.
Thank you
Xperia Play R800i
Android version: 2.3.4 (Gingerbread i guess, but don't know where to look it up)
Build-Number: 4.0.2.A.0.69
Kernel-Version: 2.6.32.9-perf [email protected] #1
If you need any further information please tell me. I can also post the report from DoomLords batch file, if its needed.

What model of xperia play? R800x, R800i, R800at, R800t?

You need a .58 or .42 firmware you can't root .69 with that method. You can flash another firmware with Flashtool.

Hmm, you need a german .42 ftf to root and OTA update to .69. But i have never found a german .42 ftf. The .42 which can be downloaded from the Android Development section is a World Version, which can´t be updated to .69 because .69 is a german market version.
There are two methods to get to .69 with root
1) Flash german .42 with Wotanserver
-You´ll have to pay 2 Euro
-Important:choose .42 AND in drop down menu 2.3.4 german generic trade
-Will erase your user data installed before
-root with Superoneclick and OTA update to .69
2) Through Bootloader
-Unlock bootloader, (official method from Sony or the alejandro guy)
- Flash a pre rooted Kernel and CWM
- Flash superuser, busybox via CWM
I´ve used method one. Didn´t want to unlock bootloader for now.

Its a Xperia Play R800i, i put that info in my first post already.
Seems you overlooked it, it's near the bottom of my post, under the thank you
@UNCUT88RAW:
Firstly thank you for the helpful post. Unfortunately the solutions you told me, do not make me smile
But i still have some questions, before I'll decide what to do:
- i'm not limited to german versions, am I? (honest question, may sound ironic)
- what would be the disadvantages if staying on a .42 world version?
- is there no other world version higher than .42? I can't imagine the german version being the highest
- aand you told me to root via superoneclick in your first solution, can't I use DoomLords kit at that step, too? I'm not too into paying, and then messing up at rooting my phone anyways xD
looking forward for your help
thank you

Just flash the f/w man (besides the 1 u r on) n root it with any method u want. Its really not a big deal to flash any f/w. Just be sure to do it RIGHT the 1st time. That is make sure u hav all the driver(s) needed install on ur pc n a working flashtool which i think u can find it here http://forum.xda-developers.com/showthread.php?t=1384535.
Happy flashing n gud luck.

I will try to downgrade to version .58 or .42, it rooted easily with doomlord kit, and i prefer .58 enhanced, it will give large internal storage also if u gonna try custom rom, most of it compatible with .58 rom version.. Its run smoothly for gaming too

@Jimmy Fake
1) .58 is the highest firmware version which can be rooted directly with Superoneclick. On .62 or .69 you need to use the methods i´ve explained earlier to gain root. You can flash different market versions (german, french or englisch market) of these firmwares, the only difference is the bloatware on it.
If you want the highest version .69 with root, you´ll need german version of .42 and an OTA update to .69.
2) .69 includes a memory fix which prevents the phone from restarting. Also has newest baseband 66, which has the best battery life and signal reception. It also contains new bloat but it can be removed through Titanium Backup. GMail is renamed to Google Mail because of a legal issue.
i know that this memory fix is included in .58 and upwards but i don´t know if this new baseband is included in any other firmware.
3).42, .58, .62, .69
4) You can root with any tools which you like.

Forgot to mention that there is a japanese firmware for Xperia Play which has 67 baseband (highest baseband). Some people say that it has the best performance in regards to gaming, battery life and signal reception. Unfortunately, it has another modelnumber (S0-015D i believe) and might give problems with some games because of it. When you change build.prop to R800i than it should solve this issue. Didn´t test that firmware. It can be found in the Android Development section of the Xperia Play.

@UNCUT88RAW
I'm interested in trying out that japanese firmware you mentioned. But got a couple of questions again.
1) If I won't like the outcome. How do I get back to my current state? Do I need to back up my current .69? Or can I find german .69 easy on the web?
2) "When you change build.prop to R800i than it should solve this issue. Didn´t test that firmware." - What exactly do I have to change in the build.prop? Shall I simple replace the build.id from the japanese version with the one for R800i?
Thank you for your help

1) You can flash .69 ftf directly via Flashtool since there´s a ftf available. Search for it on the web. However, userdata might get lost.
2) There´s a line in build.prop where the modelnumber is saved. I think it has the name ro.modelnumber. But i don´t know it exactly. Please google after build.prop for further details or look in the xda forums. To edit build.prop you need an Fileeditor and root.
Link for japanese firmware: (Please read the thread.)

Firmware must be rooted through unlocking bootloader. Use ftf for Flashtool.
