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

Yes, IMO.
3. Do I need to have the SIM unlocked before unlocking the bootloader?

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.

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

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...

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.

Yes, you can install Clockworkmod recovery from the market, there is an auto installer for xperia. That can be done without unlocking the bootloader but you must be rooted.

I believe a nandroid backup on CWM would do the trick, but I am not sure. I simply made backups of everything I uninstalled so I could revert it.

Yes. kernel flashing on locked bootloaders brick your phone. and AFAIK, no custom rom except those based on stock have touchpad support.

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.
Hi all, im a newbie here, i bought my Xperia PRO a month ago, and rooted it on Android 4, using a great tutorial in this forum and thanks to other members i got it right and rooted it in my 4 first days of use. But, i now want to upgrade to a Custom ROM and use a custom kernel , to get my phone to a new generation.
And my question now is, how can i flash a Custom ROM (i was thinking of CM9 stable when it comes out), and flash a custom Kernel with it (i was thinking of Ultima V1.4) and then keep my old applications, or most of them.
I have CWM Recovery 5.5.0.4 installed using X-Parts , and also Titanium Backup Pro . My Bootloader is still locked and i have flashtool and all drivers for my phone installed on my PC.
I would be very thankful to anyone that is able to help me do all these, or if needed, recommend me a better Custom ROM and Kernel, and then explain how i can O/C my phone too, and keep if possible most of my apps.
Also, please tell me if i have to install anything else, or if im missing anything.
Thanks in advance.
Hi mate,
First of all, I take it that you know that you have to unlock your boot loader to install custom kernels and some custom rom's. Like CM9 and 10.
ROM Install Instructions
There are normally instructions that are in the first or second post that explain how to install. If there aren't any, I've copied the instructions from maxio1998, so all credits go to him:
1. Download .zip file and place it on SD card
2. Download and flash kernel you like (or not, if you have locked bootloader)
3. Download WiFi Modules of chosen kernel and place them on sdcard
4. Go to CWM Recovery.
5. Wipe everything! (This means everything but the SD card, or you'll use all you files)
6. Flash zip with ROM
7. Flash zip with WiFi modules
8. In CWM go to "Advance" and fix permissions.
9. Reboot and enjoy [~xDevilCharged~] and PentaPowerful~ Jelly Sandwich!

Kernel Install instructions
To keep it simple, heres a program that doomed151 made. It flashes the .img without having to use command prompt: http://forum.xda-developers.com/showthread.php?t=1551073
Right, onto keeping your apps. As you need to wipe everything to install a new ROM, you can't keep your apps without backing them up. Titanium backup is the best option, and you've bought it, even better :victory: The wipe will not delete the backups from the SD Card so just place them somewhere on there.
You can use any overclocking app from the market as long as you let it use superuser or supersu. Don't recommend passing 1.3, it gets very hot and the cpu will burn out quicker. (Yeah, I know i've overclocked mine to 1.5, but it gets very hot and runs out of battery quickly)
As you've already got CWM installed, you'd be better doing a full nandroid backup, just in case you decide to revert back to stock, you have all your apps installed
Unfortunately, I'm using the arc, so I can't recommend any kernels or ROM's to you. Sorry.
If I've missed anything you need to know, just let me know. I'll try to help
Awesome! Thank you very much my friend, very detailed and nice guide. I'll wait for CM9 stable to be released for my phone an then ill try it out.
Thanks again.
Also, I've searched enough, to believe that cyanogen mods, are the best and most recommended custom ROMs, about the kernel, I aint so sure but ill see what other user's might say.

If i remember right, CM9.1 (stable) has not yet been released for iyokan (MK16i). So that means i have to wait. Also, i can flash a ROM and use a kernel other than the ROM's default one, right? (i want CM9.1 with Ultima V1.4 Kernel)
And one more thing, i have moved all apps to the SD, what will happen to the files there? Will they remain?

I think that you have to use the cm kernel (fxp kernel). Could be wrong though, not really looked into it.
Any apps that you have installed on your phone will be deleted. You have to back them up and then restore them. It doesn't matter where they are installed

so, how can i be sure if it is possible to flash CM9 with Ultima Kernel?
Also, do i have to do anything with google apps? And flash another baseband or something like it?
And last but not least, i have installed CWM using X-Parts, will this affect anything?

Sorry for late reply, just look up the thread again.
Best thing you could do is ask a question the Ultima Kernel thread and hope you get a response. But I think that it will be for stock only, (I think they need different things in them....) but im not a dev, I don't have the patience..... :laugh:
You might have to flash google apps. Just use CWM in the custom kernel you choose. They will be a link in the bottom of the first post to the google apps download.
No need to flash another baseband or owt like that. When you flash the full zip of CM9 in CWM it will add and edit everything you need.
CWM from X-Parts will not have any effect on anything after you flash a different kernel. It will disappear like it was never there.
Hope I'm able to help again Need anything else, just post again, I will pick it up
Good work Jon565G
Not just good, excellent work!
I did it, and flahsed the kernel and all that stuff, now i reinstalled all my apps , and O/Ced at 1.2Ghz , and everything is nice.
But, working on android stuff, makes you want more and more, and as you learn better, that makes you want even more, and now i want to mod another phone.!
I've learned a lot from your help and the help of other members of this forum, and i think i am now ready to "mod" more phone, just for fun.
I already managed to flash an x10 mini with miniCM7 and flash a nAa Kernel, and also flash another x10 mini pro with miniCM7, and probably today ill mod another friend's x10 mini. And later two x8.
Learning, is great, thank you all.
EDIT: I also found out that everything you need is Flashtool, its the best tool out there, it flashes, it installs Busybox, recoveries, it unlocks bootloaders, it roots, it flashes kernels, everything. .Ok you might also need s1tool to check about the semc lock and if you unlocked the bootloader.

I know, I'm the same. I'll want to go and buy about 10 different android devices just to have a play around and mod them. It's always nice to play around with 2 android devices (Please come back in stock Nexus 7 )
Anyway... I'm just glad that I was able to help to introduce you to the world of android modding.
Have fun, that's what it's all about :victory:
(I had to use multiple programs, my bootloader could only be unlocked my test point. Was locked to T-Mobile. Best use of flashtool is when you've bricked it and need to get it back to stock )
I hope you get back your Nexus 7 then
Yeah, i unlocked my Bootloader using testpoint method too, so i wouldnt get any bricks with FOTA updates. And, i also used to be into such electronic stuff.
And, you didnt just introduced me into Android Modding World, you made me a fanatic Android Modder
Anyway, thank you once more, and yeah, thats the point, the fun about all these stuff

I am not sure, but i believe, that either you have locked or unlocked bootlader, it will always say "Bootloader Unlock Allowed: Yes , or No if its not allowed).
I aint sure, because in CM9.1 i dial it, and i cant get to the Service Settings, so i cannot be sure.
And, as i've found out, you can be sure if you have locked or unlocked bootloader, by running S1tool, and pressing "IDENTIFY" , which will tell you to connect your phone in flashmode (phone off, connect USB while pressing back) , and it will give something like "loader version xXXXXXX" , where the capital X , are numbers, and the small x, is either "R" or "r". If it is a small "r" , that means its unlocked, if its a capital "R" its locked.
If you want to unlock your bootloader in the Xperia Pro, just tell me , and im sure i'll help you out, with a detailed tutorial, without having any problems.
Hope i helped.

Understanding the Rooting Process
Hi,
I have never rooted a phone before, so I am a bit curious before I get into it. I have a Galaxy Nexus – brought directly from Google without going through any carrier. I have Android 4.2.1 on it, and it has never been rooted.
I want to root the phone in order to copy data on and off a USB Stick using Chainfire’s Stickmount App (among other things.) This means I am not interested in any custom ROM. The stock works OK for me.
I am using the following tutorial: How to Root Galaxy Nexus! [Universal Guide][GSM/Verizon/Sprint][Windows/Linux/Mac][GB/ICS/Jelly Bean] which has the following steps to root:
1. Unlock the Bootloader
2. Install ClockworkMod Recovery
3. Install the SuperUser binaries using Recovery to get Root
In this regard I have a few questions that I am not getting easy answers using Google. (All I get is tutorials with steps – no logic.)
1. The first step is “Unlocking the Bootloader”. The following link says that unlocking the Bootloader is to install custom ROMs What does it mean to unlock the boot loader?
As mentioned above, I am not interested in putting custom ROMs on to the device. I am satisfied with the stock. Do I need to do this step?
2. “Unlocking the Bootloader” seems to delete all data on the phone. Is this true? Why does it do this.
3. Is it possible to backup the current ROM before I root? That way I can always restore it in case of any problems. I do not have much data/apps on the phone, so backing up that is not an issue.
Thank you all for your help.

1. Yes. Unlocking the bootloader is not the same as installing a different ROM, you will still be on stock after unlocking. Unlocking will ALLOW you to flash different firmware/mods/etc, but you dont have to flash anything you dont want to.
2. Yes, it will wipe your phone clean. Every time you do it. No getting around this.
3. Not to my knowledge. I would recommend doing the back up first thing after unlocking bootloader and installing recovery.

its really irrelevant to backup the rom if you're staying stock since you can just download the images freely from google and use fastboot to flash them all and you'll be running a clean stock rom since you just unlocked the bootloader.
Thank you WiredPirate & Zepius. I am trying to understand how the Rooting process works – not just the steps, without having a clue as to what I am doing.
1. My question here was not “Whether I needed to Unlock the Bootloader” – but why do I need to Unlock the Bootloader in order to Root? My question here is Why? When I do not need to install custom ROMs why should I be unlocking?
2. Why does Unlocking the Bootloader wipe the phone?
3. Thank you Zepius. I think I agree with you here.

This is true. The exception might be if you don't have access to a comp at the time your phone needs to go back. But downloading and flashing images like you said is probably a cleaner/ better way of getting back to stock.:good:

1) an unlocked bootloader allows you to flash unsigned images. This allows you to flash a custom recovery, which is required for root access. basically, if you want root, you have to unlock the bootloader the first time with the command "fastboot oem unlock"
2) thats the way its designed. there are ways around it, but you have to have root to unlock the bootloader without wiping your data.

The other option if you want to root without losing your data is to use a computer with the adb tool to make a backup and then restore that backup after you've rooted your phone. A guide on how to do this can be found here: http://www.thesuperusersguide.com/adb-backup--restore.html

Another option for USB OTG is an app called Nexus Media Importer it almost does what stickmount does and does not require root.
You can read data, but you cannot write to the attached device (USB flash drive etc.), only copy to the Android device.
Hope this helps a little in case you are uncomfortable rooting.

As has been mentioned, unlocking the bootloader is necessary to allow flashing images. AFAIK, the data wipe (factory reset and memory card wipe) is to protect your data, contacts, etc., in case your phone is lost or stolen and somebody tried to restore your phone to stock so they can use it or sell it. That's assuming you have a security screen that can't be bypassed so that the criminal can't just hit "factory reset" and delete your memory contents.
The bootloader unlock is necessary to root because you are flashing the custom recovery (TWRP or CWM) and root (Superuser or SuperSU) binaries, or flashing an "image" if that helps. This is the same process as flashing a ROM, so the bootloader needs to be unlocked to allow this. The data wipe is there to "protect" you.
Once rooted, you can lock and unlock the bootloader at will with the "Bootunlocker" app by Segv, though if you ever loose root via OTA update, you have to unlock the bootloader via fastboot again, which causes you to loose your data. I learned this the hard way so trust me, just leave the bootloader unlocked. Even if a criminal tries to flash a new ROM or factory image, they have to completely erase everything to get around your security screen.
If you have data that want to save, use the Android MTP to move you memory contents to your computer. This is mostly for music, pictures, documents, and downloads. To do a full backup (apps, settings, data) there is a guide in the stickies I believe that explains how to do a full backup to your computer without root.
That is my attempt at the logic, hope that helps.

I am new to the nexus 7.
Can I root without unlocking the broader?
What is the side effect of unlocking the boot loader?
Is there existing method to root without installing customer recovery?
Thanks

There is currently no known way to root without unlocking the bootloader and using a custom recovery.
Unlocking the bootloader allows you more control over the tablet. Specifically to install custom recovery, ROMs, etc. Most of the benefits from an unlocked bootloader are things you do from a custom recovery, not through the bootloader itself. The only real negative 'side effects' are that you lose some of the safety benefits, since you can do dangerous things if you don't know what you are doing, and that it may void your warranty.
So, if want to root, I must unlock bootloader?
Well I still get ota with bootloader unlocked?

1. Yes
2. Technically you can, but not recommend; just wait for the rooted stock and flash that.

Regarding your #2, there is no reason not to unlock the bootloader to get OTA updates. The only thing that breaks OTA is custom recovery.

Completely correct. I just said not to do it, cause he seems less experienced, and from my experience, they get freaked out afterwards trying to put it back on. So trying to save him a headache, lol.
I recommend staying stock unless you absolutely need a specific root required app.
Right now there isn't a reason for root access except titanium backup.
I do recommend, however, to go ahead and unlock. It will wipe your device including personal data, so might as well get that out of the way now before you risk losing something important.
You can easily flash a custom recovery and root anytime after that, but I would wait until knowledgeable devs figure out the device a little more first.

I'm not sure why you would suggest people not to root now. You mentioned a very good reason to do so - Titanium Backup. Not only is it useful for backups in general, but it's also a lifesaver for copying apps and their data from one device, like someone's old N7, to their new N7.
While I would certainly agree that people should wait before flashing custom ROMs, kernels, hacks, etc., nothing is going to change with rooting your N7 today versus a week or month from now. All the pros and cons will still be the same.

They guy doesn't need root. He also doesn't understand root. So his chances of softbricking are good, and then, instead of us trying to talk him out of rooting, we now have to talk him through how to fix it.... .. Can we count on you to provide this support since your are so OK with him rooting now?

Neither you nor I have any idea what he needs or doesn't. He hasn't said anything other than asking some basic questions about the process. There are numerous guides on here that walk people through rooting step by step. There are also a handful of people who have soft bricked their device and asked for and received help. And yes, I have assisted people with similar issues in the past. Everyone on this board has at one point in their lives screwed something up - that's how we learn.
In any case, my point was that there is no clear reason for him not to do it if he wants to. The device is pretty forgiving unless he kills the bootloader.
Hello everyone!
I just don't get it. Can anyone explain to me what's the difference between flashing a bumped rom and flashing the same rom un-bumped? I just don't get the whole point of it! Sorry, but coming from a Nexus device (why have I ever changed!!!) I'm new to these things.
So, other questions would be: what's the point of bumping? What if I don't do it and just go about the usual way: Unlocking the bootloader, rooting and installing a custom recovery and then proceed to flash the appropriate and preferred rom, kernel, etc?
Hope somebody will bear with me and try to explain these things to a newcomer
Thanks

Because
1) Bumping is used to trick the bootloader into thinking that the boot.img is authentic and from Official LG Sources
2) Without bumping you could have to constantly run fastboot boot boot.img (an example of this was CM11 when it first started development)
3) Bootloader cant be unlocked at this time so we rely on a bootloader exploit in order to run custom recovery
4) Its all about the authenticity. If the LG bootloader does its security checks and anything fails then the system doesnt boot
Thanks for the very easy tuo understand explanation. I should have thought that the problem was unlocking the bootloader! Guess I'll have to with the Flow and bump my new phone. I wish I asked my Carrier for an HTC M8

simple answer: bump is the only way to unlock g3 bootloader.
all roms are bumped whether displaying [BUMPED] or not.

Ok, so by simple logic, once I have installed, either via bump, flashify or ADB a recovery, I can pretty much flash any rom that is appropriate for my model no, isn't it?
So there is one more question I have: what is the purpose of unlocking the bootloader and then what could be the problems if I don't? If everything I flash for this device (TWRP, roms, kernels, etc) is, by default, bumped, what's the purpose of installing bump at all?

You're making it so much harder for yourself dude.. There really is only one way to install custom ROMs and that is by Bumping your phone. That's it.
You go here and read the entire topic. Don't miss a single thing.
Then go here and flash the zip for the latest TWRP.
After that you can install any ROM in the OG and Android Development section.
That's all there is to it. You can read in those topics for more information about what they do.
if you dont bump, then you wont have twrp lol.
you cant flash any roms anyway, you'll potentially brick/soft brick your phone.
roms etc are bumped because they have a patch script implanted to run on the phones correctly.

OK. Got it! It took a while, but I give up!
Thanks for the help. Coming from the most easy to play with phones (only Nexus so far, but I hate the N6), it isn't easy to have to deal with more stuff than usually needed and hence more complications than usually had.
I thought that, after rooting I could flash TWRP via flashify or rom toolbox and then I would have TWRP without BUMP, but it must be that I'm missing something, if you say I MUST bump my phone to install TWRP.
Thanks and see you around

What exactly do you mean "How to bump"??? Bump and loki are bootloader exploits that allowed us to boot TWRP and all the benefits TWRP offers... On the user side of things you don't "Bump" anything- the Roms, Kernels, and recoveries are "pre-bumped" by the developers and 99.9% of the time they will say whether or not it is "bumped" or "lokied" although loki is really outdated and I doubt you'll encounter it. So in a nutshell we(the user) doesn't "Bump" anything and just make sure to really read before flashing
