[Q] Xperia Play Beginners guide?

Hey guys! I'm picking up an Xperia Play in a couple of days and was looking for some general advice about the phone. This will be my first Android device, I've been on WebOS/Garnet for my last two phones. I'm just a little overwhelmed with the options presented by the Play and Android in general. For instance, I'm not sure if I should root my phone or not - what are the advantages?
Any other general guides to Android/the Play would be wonderful if any such guides exist. I'm looking to deck this thing out with every emulator on the market as well as get the PSXperia hack up and running (I've downloaded the program, but can't figure out how to use it).
You can sense my overall noobishness in general, I'm sure. Any advice or tips about this device would be great. I'm really excited about the Play and getting comfortable with Android. Thanks everybody!

congratz im waiting for mine is the mail right now lol
rooting allows you to have full access to the file system sorta like a administrator
on a windows machine since out the box you cant edit files or remove bloatware without root you cant install certain programs from the market without root
also having root and unlocked bootloader allows you to flash a custom recovery image which will allow you to flash customs roms(a custom version of android dev by a user here on xda or anywhere in general)
yes i highly recommend but if you ever plan on returning the phone to verzion for example you will have to revert it back to stock
and for the program psxperia you need to install the latest version of java from java.com
and if your on a windows machine you double click the psxperiatool.JAR file
and it should run not sure on OSX
in the end you made a good choice on choosing android as mainstream as it became its still a powerful system way better IMO than ios or even webos
since android has so many developers theres gonna be an endless amount of programs
will post new finds myself etc

You cannot flash the recovery image directly or you will mess up boot partition, you need to flash a kernel with embedded recovery built in

Thanks for the info. I'm confused about the locked/unlocked bootloaders. How do I know which one I'll have? And how "easy" of a process is rooting the phone if I don't plan to install any custom roms or anything?
Also, how does transferring .apk files from my PC to the device work?

If you havent unlocked your bootloader yourself it is locked there are many risks and advantages to unlocking your bootloader, but if you dont intend to flash custom roms there really is no need, just like with root, if you dont know what it is, you probably wont need it
transfering .apk's from your pc is easy, just copy the .apk to your sd card, then use a file manager to find the .apk, tap on it and the installer will pop up , you need to tick unknown sources in settings though

hes asking about android in general not aiming specifically at the xperia play

If I root my phone, do I have to switch everything back in order to get updates? All I really want to root my phone for would be to remove bloatware/speed it up a bit, is there a better way than rooting?

There is plenty of tutorials here, I suggest that you read, read, and then......read some more

Thanks so much for this link, it's seriously going to help me while rooting my phone. This might be a dumb question, but bear with me - better safe than a bricked phone. The guide to rooting in that link says that I need to flash my Play to the .184 Generic UK firmware...am I understanding it correctly that I need flash this firmware onto my American Verizon Play? I want to make sure nothing is going to get screwed up regionally, as I'm going to want to keep getting OTA updates and all that.

Just to share my own experiences since I'm new to the Xperia Play (previously had an Acer Liquid.. crappy hardware but great community of devs.. anyways..)
I'd recommend rooting your phone off the bat - the simple reason is rooting will involve wiping your phone's data, so if you already have a few months of use that means having to restore everything which is tiresome. First thing when my phone arrived was follow the rooting guide here - http://forum.xda-developers.com/showthread.php?t=1116090
After that however I wouldn't recommend messing around TOO much with custom firmwares and such etc.. get used to the phone as it is and figure out what you like, don't like. if your like me within a few weeks or months you'll want something new - this is when you might want to start looking at messing around with the phone - new home launchers or even a new ROM (if your phone can have it's boot loader unlocked, from what I understand mine can't). The games and Emulators should keep you busy as is
The only customizing I've done to my phone is rooting it with Gingerbreak and using the leaked Sony Launcher.

I realize this is a pretty nooby thing to do that annoys all the veterans, but I consider this to be a fairly crucial piece of information I need before I attempt to root my phone, so I'm just gonna go ahead and bump this thing before it gets lost in the shuffle.
In order to root with a locked bootloader on an American Verizon XPlay, I need to flash to the .184 generic UK firmware, then root, then OTA update, correct?

No. That method will not work on the r800x (verizon xplay) to root yours you will need to see [How-to] R800x Root
Dont worry about annoying people lol . Who cares what others think? Everyone has to start somewhere.
But it would be better with a stickied thread for new users to look @.

So now, instead of the 3 step process linked previously in this thread, I have to unlock the bootloader and do a whole bunch of other stuff? This method is like 100x more complicated. Is there no other way? I don't intend to install any custom roms, I strictly want to root solely for freezing bloatware.

No i dont think so. You would be better asking for help from other r800x owners in that thread.
The exploit gingerbreak uses on 2.3.2 was patched in 2.3.3 (worldwide) and was also patched by verizon before they released the handset on 2.3.2. Up untill the bootloader was unlocked on the r800x rooting was not possible.
Ask in that thread and you should recieve the help/info you are after.

Bunch of questions, terrible newbie

Okay. Here to learn as much as I can, if you can number your responses with the questions and add whatever you believe is best. Thanks. ^^
Bootloader:
1. Do you unlock a bootloader JUST so you can load custom roms?
2. Is the method of unlocking the bootloader on SE's website the best way?
3. Do I need to have the SIM unlocked before unlocking the bootloader?
4. What is the point of custom roms?
Rooting:
5. Can I remove the apps here; http://forum.xda-developers.com/showthread.php?t=1046699 just by having root access? No special tools needed?
6. Are there other good methods of optimizing things like battery life specific to the xperia play?
Sim Unlocking:
7. Is there any method of doing this without a cost?

I'm on an R800x, which doesn't have sim card anything, so I'll just answer the questions I know.
1. Unlocking the bootloader allows you to install 3rd party software that overwrites the stuff that is part of the boot process. This pretty much refers to the kernel, for the Play. Certain roms, such as MIUI and CM7 require you to use a kernel different from stock, and since you need a different kernel, you must have an unlocked bootloader. As far as I know, that's the only real benefit for an unlocked bootloader, from a user standpoint.
4. There are many things that custom roms offer, as opposed to the stock your phone came with. This can range from a new UI, new apps, tweaks to system files, etc. Generally speaking, developers strive to make their custom roms operate better than stock. For more information on this point, I would suggest you check out some of the custom rom threads, just to see what they've changed from the stock rom.
5. You will need root, but you will need something with which to remove the apps. The best app to use, in my opinion, is Titanium Backup. Not only will it allow you to remove system apps, but it will also back up those and user apps, all for free. Unless you buy the pro key, that is.
6. As far as specific tips for the Play, I would recommend rooting so that you can disable the auto brightness. While auto brightness is desirable in most phones, the Xperia Play (And other Xperia devices, I think) are almost constantly shifting the brightness, to where a slight tilt of the hand can make the screen dim or brighten. I'm sure that can't be good on the battery. Generally speaking, though, apps such as Juice Defender and Battery Defender have profiles or just general settings to adjust data flow and many other options that can significantly increase battery life.

To the best of my knowledge
2. Is the method of unlocking the bootloader on SE's website the best way?
Click to expand...
Click to collapse
Yes, IMO.
3. Do I need to have the SIM unlocked before unlocking the bootloader?
Click to expand...
Click to collapse
No, but you can check if you can unlock following the instruction on SE's site:
1. First, you should confirm that it is possible to unlock the boot loader of your phone by checking the service menu. In your phone, open the dialler and enter *#*#7378423#*#* to access the service menu.
2. In your phone, tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
Note that unlocking void your warranty.
7. Is there any method of doing this without a cost?
Click to expand...
Click to collapse
Not that I know of.

Awesome guys, Thanks a bunch.

Unless you're really tight on space (which shouldn't normally happen if you've done the adb setinstalllocation trick and moving apps to sdcard), i would suggest freezing the apps instead of removing them especially if you're sticking with stock. This would make it a lot easier to move to the next official OS upgrade instead of a mad scramble to find the stock apps and reinstall them. The pro version of Titanium backup and SystemCleanup has the freeze function. I've freezed a lot of crap on my phone and it makes a world of difference wrt. boot time and general performance.

Unlock boot loader is very good allows you to flash custom kernel and overclock

@JulianPaul/Vabene2002: Not sure if im sticking with stock, My model is R800AT. So not sure of my options yet. Im still trying to absorb as much as I can.
Wonder if I asked some more questions if they'd be answered.
8. Is there any recovery utility WITHOUT unlocking the bootloader? Say I mess something up with my root, Can I recover back to an original ROM?
9. Can I back up my current running ROM as soon as I get my phone so that I may return it to that state?
10. If you need to change your kernel to match a modified ROM; Your current ROM wont support it, so you need to change kernel AND ROM at the same time? Otherwise your phone wont boot?
11. Any decent links for rooting an r800at?
12. Is gingerbread the latest version of android an xperia play can run and have jailbroken?

Would having root access void the warranty? I want to remove some pre installed apps so is there a way to do this without voiding the warranty?
Thanks
Sent from my R800i using XDA App

Yes, it will.
But if you just recover to a stock ROM, then its like you never rooted.
Thus, warranty reinstated.

Nah, don't want to risk it yet. May never root this phone actually...
Sent from my R800i using XDA App

Im going to root mine as soon as it arrives. Lol.
Not to diminish your opinion, If you dont know exactly what you're doing, it could get ugly.

I rooted my old ZTE blade but this phone is just... different. I mean it's probably gonna Get ICS anyways and if I were to root I'd probably need a very simple guide.

If you keep it stock, yes, 2.3.4. There is FreeXperia rom that is 2.3.7 as well.
On the forum you will find links to ICS based roms, SE leaked and AOSP. Both are WIP, I believe.
I've read somewhere that Sony will release ICS for the xperia 2011 line around April.

pretty sure flashing kernels on locked bootloaders doesn't BRICK your phone. It won't allow the kernel to be flashed as you can't use Fastboot only flashmode (official signed Roms only )

Doesn't brick as in "turns your phone into a very expensive paper weight", but your phone will not boot anymore and you will have to flash a stock rom with flashtool to recover.

Which comes first?

Had been using my mobile since March.Originally gb 2.3.4 and now upgraded to ics 4.0.4.The upgrade was done at a SE service centre.
Had always been fascinated about doing hacking but do not have the knowledge.Read a lot of stuff on so many different sites still hard to absorb.
Read recently that one need not unlock the bootloader of an xperia arc lt15i running on ICS 4.0.4 build 4.1.B.0.431.I do not know if it's true.
But my question is when you have a mobile device with original specs and you want to clear some stuff to get extra memory what needs to be done first.
All the other tutorials seem outdated because of the new version and the build.
Does one need to unlock the bootloader now?Is there a proper step by step guide to do rooting?By proper,I mean starting with the device.What needs to be done preroot.Than what files needs to be downloaded and from where.I know what I've stated is already available.But some I believe have missed out tiny details relevant to the process and hence all the negative comments.Which actually scares you to pursue your goal of rooting your device.So anyone here that can guide me?

This may well be the best and yet the shortest guide to do the entire thing:
http ://wiki.cyanogenmod.com/wiki/Sony_Ericsson_Xperia_Arc:_Full_Update_Guide
Yes, you'll need to unlock the bootloader with the code provided by Sony.
Installing CM7, CM9 or any other similar complete system automatically makes you get rid of the manufacturer add-ons.

[Q] In need of guidance :)

Hello, and sorry for bugging everyone, but I have somewhat of a problem. I'll just start from the beggining.
First of all I own a SGS II, so I'm used to flashing roms and kernels custom stuff and all...on that. My girlfriend is the one who owns a Xperia Arc S (LT18a, US version if it's relevant or not). And for the live of me, I can't summon the courage to flash it, the process being somewhat different than the flashing of a S2. That's just idiot proof in my opinion, can't go wrong. I'm seeing all over the place guides and stuff for flashing a Xperia Arc S, and don't really know wich one is good/bad etc. So...the actual questions :
1. Where can I find the stock firmwares for Xperia Arc S ? I was hopping on a website something like sammobile for samsung, where I can find every release etc.
2. She now has 2.3.4 (I think not 100% sure) build 4.0.2.A.0.62 and from what I heard that cannot be rooted, or it involved something like unlocking the bootloader or something like that, safe to say that kinda freaked me out a bit.
3. I'm guessing that this build 62 is like on my samsung, where different stock rom's are differentiated by letters (eg. XXLPG, XWLPQ etc) so, someone please confirm that.
4. Is there any noticeable difference between these gingebread builds, cause if build 62 can't be rooted, I'll downgrade to previous build that can be more easily rooted.
5. I really need a idiot proof guide to flashing this thing. She has no warranty on it and I really don't want to mess it up
6. And last (finally, I know ) some links for safe versions of flashtool (equivalent of odin from what I understand) and firmwares, stuff I need to root it etc.
I apologise for such a long post but this stuff is pretty overwhelming for me. Also I apologise for spelling errors (english is not my first language)

Wow, the things we do for love...
OK, here's a quick run-down of how it works.
Firstly the bootloader thing: -
The bootloader is where the "kernel" sits. If you unlock the bootloader then you can pretty much put anything on the phone.
You can flash a custom kernel, and from there on you can use ClockworkMod recovery the same way you do on your Samsung.
(
custom kernels have ClockworkMod recovery built into them since the XPERIA doesn't have a "/recovery" partition for the standard ClockworkMod recovery.
If that didn't make sense then here's a translation "There's no special space for CWM recovery on Sony phones! So custom kernels have CWM recovery built in for easy access."
When one of these kernels starts up the phone there's a point where the hardware buttons light up, and the LED flashes purple. If you press "volume down" at this point then the kernel starts up ClockworkMod recovery instead of booting the phone.
Most roms come with their own kernel that you can use like this. The XPERIA is different to the SGS phone because you can't flash a kernel from the phone itself. You need an unlocked bootloader and fastboot to flash a kernel.
)
So unlocking the bootloader is a good idea, but only after you've made a backup of all your stuff off the memory card.
Here's a really good thread that brings together all sorts of pieces of information that you might need to root the phone - http://forum.xda-developers.com/showthread.php?t=1653188
OK, so that's the unlock thing, and the kernel thing. Once the kernel has CWM recovery built in you can pretty much flash any rom you feel like flashing. There are already some JellyBean roms out that are fast and usable if you're prepared to read up on them and experiment a bit.
Next thing is the "BaseBand". This is the driver for the "cell phone radio". The part of the hardware that's actually responsible for behaving like a phone
Here's a thread where you can get all of the different base-band versions: - http://forum.xda-developers.com/showthread.php?t=1688049
Personally I know that base-bands 72 and 77 both work perfectly. Since they are the 2 newest versions you can choose which-ever one you want. The newer basebands give much better signal strength on the phone, and the call quality is really good.
Good luck with the experimenting - hope you enjoy.

Not really, from what I hear ICS dumbs down the phone sort of speak. Now I really can't say, but I would test it out a bit, as long as I learn how to go back to GB.
Another thing that I'm a bit concerned is that all the stuff I find are for LT18i and my gf's phone is a american model LT18a. Will this be a problem ? Or that's just to differentiate the hardware stuff in them ? I hope flashing a LT18i firmware doesn't screw anything up

Yep, the differentiating factor is the hardware. the lt18i and lt18a roms are the same as far as I know. ICS does tend to be more resource heavy especially on the arcs but downgrading back to GB is basically the same method as flashing the ICS, just with another rom.
And also, in response to your first post, you can downgrade to the rootable build of GB, root that, and then flash the build 62 kernel back onto your phone so it's rooted and of the desired build
There's a lot of flashing guides on youtube regarding the arc s. I did a quick search and this one seemed pretty accurate and straight to the point.

Ok I pretty much understood the whole shabang, my last question is about the bootloader, if I unlock it once that's it ? I can flash whatever I want and not need to reunclock it...sort of speak. I read that for warranty reasons it can be relocked but that's not the case for me. Also for flashing a stock rom is it necessary to unlock the bootloader or that's just for rooting ?
Oh and almost forgot...if I understood right...I can downgrade...root...then upgrade to 62 and it will still be rooted ? On my samsung if it'a rooted and I flash abother stock rom...bye bye root, so pretty weird for me. Thank you again, I can't stress enough how helpfull you guys were.

unlocking the bootloader allows a whole lot more things to be done with the arc, but does make some apps defunct such as track id and music facebook like (which many can do without). flashing and/or rooting a stock rom doesn't need an unlocked bootloader because it's stock and yep, you can downgrade/upgrade, root, and then go back to what build you want by flashing a kernel only

Follow the instructions up to the point just before patching and tell me what it says please?

if you unlock the bootloader NEVER UPDATE OVER THE AIR this will brick the phone.
The're 2 ways to unlock bootloader
1 via Sony web site but this only works for non branded phones,
2 is to pay if you use a service with setools this will unlock bootloader and make phone SIM free.

[Q]Want to ROOT & REMOVE ICS upgrade & go BACK to Gingerbread..???.

Hi Everyone!
I have an Xperia Arc that I got through Rogers. It had been running Gingerbread 2.3.4 and the ICS update didn't arrive until a year after I got my phone. I read that it wasn't really recommended to do the ICS upgrade even though it had become available (according to Sony). I had been waiting for SO long to check it out that I took my chances on the 50/50 good bad reviews on it and went ahead with the ICS update when Sony/Rogers released it.
BIG MISTAKE.
At first I didn't think it was that bad - but now after having it for a few months- I HATE IT. My phone runs like S***. It's slow laggy.
I had been wanting to root my phone for a long time (I want to get rid of all the bloatware software and be able to use firewalls and tweak CPU speed).
I was all ready to root and use a custom ICS ROM - but I thought about it and I would rather have GIngerbread back on my phone. My phone was awesome when it had Gingerbread and all I ever want to do now is smash my phone - it just can't run ICS properly.
So here is what I want to do:
1. Root phone - I have already downloaded FLASHTOOL, and the DOOMLORD V4 Rooting tool.
2. Flash phone and get RID OF ICS
3. Install a custom ROM
I just need a bit of help.
I need clarification regarding the ADB Drivers.... I have read in numerous places that by just having the up to date Sony PC Companion that you will have the ADB Drivers needed - and I already have the most up to date Sony PC Companion.
I also need some tips regarding ROMS and KERNELS. I understand they are different and they have to be compatible but when I was originally getting all my files for ICS all I found was a kind of 'all in one' - maybe I was confused - and this is why I need some clarification. Do I need to have a separate ROM and KERNEL otherwise then what do I do?
THANKS!!!! rEBECCA

Click the first link in my sig, read it, then come back and ask about anything you're still unsure about.

Thank you for your quick reply. I had actually already read it. I DID read it again though... I picked up a bit more knowledge from the 2nd read but it still didn't clear up a few things.
I'm still not clear on the ADB drivers, I saw all the tutorials about ADB for noobs etc but I'm reading on a LOT of places that just having Sony PC Companion installed and up to date will have the ADB drivers...
I should also let everyone one know that my phone is a ROGERS phone, so my bootloader is LOCKED. I have figured out that there are some ROMS that will work on a LOCKED (carrier (rogers) bootloader.
I currently have Android 4.0.4 (I did the update when it came avail to me and I regret it - i really need gingerbread back) I would also like a rom that doesn't have all the Rogers 'bloatware".
All I want to do is undo the stupid ICS update I did and get rid of that HORRID Rogers bloatware!
Through all my reading over the last while I've learned of 'omnius' - I guess it will unlock my bootloader, root, flash and do lots for my phone. Anyone else recommend this for my situation?

Flash a stock GB ftf and go from there, which will debrand your Phone in the process.
