I have to lock bootloader after installing kernel? - Sony Xperia P, U, Sola, Go

Okay, im new at this android stuff and im gonna say "sorry for my bad english" before i start to write it.
I just unlocked the bootloader and i did setup the "Advanced Stock ICS Kernel"
The Superuser app works great. (I think i might open root access(And thats what my purpose to do all that things.))
But, i just wanted to ask some questions. So;
1-) I have to lock the bootloader again? Because i saw something in internet named "Installing app's with unlocked bootloader is dangerous."
Is that true?
2-) If i lock the bootloader, will i still be able to use root access?
3-) The cellphone says "A new system upgrade is available" if i upgrade it, i will lose my root access? (And the upgrade is same with my version.)
Can i delete that reminding from the top of the screen?

You don't need to relock.

It also shouldn't tell you of system updates if you're unlocked?

recovery without bootloader unlocking.. possible?

so i'm about to install 4.5.91 in a few hours.. gonna backup lots of data first..
im trying to avoid bootloader unlocking for the meanwhile cause of the warranty issue and the fact u cannot re-lock.
anyway i just grabbed ATT-2.3.4_Pudding_preroot.rar and ill flash it over the gladiatrix 1.8.3 i have currently on the device (will it work?)
later i intend to use the preroot method and root and of course.. install a recovery BUT.. since the new recovery needs an unlocked bootloader.. ill use the previous one with the battery charging hack
so.. what do you think guys? will it work?

I would assume the att-2.3.4_pudding_preroot already is preunlocked (hence the pudding) which defeats your purpose?
Also, what would the purposed of the old plugged in Recovery? It won't install any of the new ROMs and I don't think the nandroid back up really works that well.
not quite.. its just have the "pudding" in it.. you'll have to perform an unlock with fastboot to void warranty.

Ok, so the other question - point of the old recovery? Just to help you wipe data/cache/batterystats?
The old recovery will still save him... You shouldn't need to be unlocked to do that.

save him from what and how? other than wiping data... he can't flash anything that can save him...
Indeed I think he can backup with old tenfar's recovery. The problem is that the sfb he wants to flash is the incorrect one, you can't use the prerooted without unlock the BL at least for the version I know. In other hand The update process is kinda complicated without unlocking the BL, if you do it OTA you will also update the BL and that one can't be unlocked now also could leave you bricked if flash back to 1.8.3.

gives stock 2.3.4 without touching bootloader.
you should be able to use preinstall method to root then i think.
He needs to unlock the BL to flash kennp image files.

Root does not equal unlocked bootloader. Read the important information in every thread before you attempt to use what they post. Else, you wind up looking like an idiot, like you do now. Now if you want to do nandroid, follow the link in the post above and unlock your bootloader.

Can I unlock my bootloader, after my phone was rooted ? Or should I unroot it, unlock the bootloader and than root it again ?
Rooting your phone, and unlocking bootloader are 2 different things.
Rooting is for your ROM, while unlocking bootloader is for your phone...

[Q] Bootloader

¿How to know if my bootloader is locked? I searched on the hidden menu and found nothing but the bootloader version. I'm looking forward to unlock it so i can root and do stuff.
I own a P768G v10a

I'm not sure it's the easiest way but you can go to fastboot with method wrote here http://forum.xda-developers.com/showthread.php?t=2221102. But first you will have to flash jb V20* ROM. If you have first screen where you are asked if you want to unlock bootloader = locked. If second screen with quick guidance = unlocked.
WARNING! Be careful if you don't want to unlock bootloader watch which button you press.
You still didn't answer his question. I would like to know as well. Is there a way to tell if my bootloader is unlocked or locked?

Of course it's locked, every phone you get will have bootloader locked. Unless you have an S4 or S3 as far as I know.

As far as I know, not every phone comes with a bootloader closed unless some phones are able to change roms and stuff without needing to open this.
If your on JB, just go to the dialer and type 3845#*760# then scroll to the bottom to bootloader unlock check. (if you have differernt L9 - 3845#*7xx# - your numbers)
Another way to check is to go to software update mode by switching off the phone then holding volume up while inserting the USB cable. If your bootloader is unlocked, it will say so in the top corner of the S/W update screen.
If you havnt unlocked it, it will be locked by default.

First of all get your self on .532 and root and then back up the TA partition, may save some grief at a latter date.
Then all I can say is try and try again, and make sure that you submitted the correct IMEI to Sony
am now on 5.10 and still doesnt work using any method

Type in *#*#7378423#*#*
Go to Service Info > Configuration
And check the Rooting Status
Does it say Bootloader Unlock Allowed: No?

yeah i done that and i get told "no"
i dunno what else to do now that am being told i cant unlock
I should read your first post better
If it is unlockable then I don't think there is any thing you can do
am confused? why wouldn't i be able to unlock?
Because your device is probably a carrier-linked one... almost every phone bought within the US, if it's not from the manufacturer itself, is locked.
You either will have to live with it, or just sell it and buy an unlockable one directly from Sony.

Sure is nice when there is a flaw in stock code that allows you to inject root (privilege escalation).
Sorry its a pet peve of mine, I'd rather an unlocked bootloader and secure system so I know that if I'm on stock nothing gets root until I'm ready for root by unlocking the bootloader.
/soapbox lol

But BL was already been unlocked?

BL was bypassed, not unlocked. Nexus devices, some Sony devices, and some HTC devices can have the BL unlocked (commands in fastboot, no root required to do) but BUMP just tricks the bootloader then requires boot imgs to be signed with the DEVs keys (from my understanding).
This means it is not a true unlock but will act as a unlock if the imgs are signed by the devs (I'm not privy to the actual method so I could be off a bit)
With a true unlock you take a step, outside of the normal system, usually wiping data in the process, to enable an unsigned recovery that allows you to flash a new system. This means if I steal your device I can't root it and install a few apps then give it back with you not knowing, or steal your CC info stored in a db file using root privileges.
Sammy and LG root/unlocks are backwards. I can take your device, install stump, delete stump, install a root/hidden tracker, and follow where you go without your knowledge, all in about 15 mins.
