Hi, so I am running the latest Paranoid Android 4.6beta3 for our device, yet the camera takes very grainy pictures in low light. I was wondering to what degree I would have to revert back to stock rom for the camera to be its normal self. Do I have to restore TA, and so relocking my bootloader? or is it enough to simply flash a stock rom like RomAur?
thanks

You have to flash a stock kernel and restore TA (relocking bootloader). You can run a custom ROM, as long as it doesn't require a custom kernel.
Ok, could you point me to one of these customs, or is romaur one of them?

I was actually thinking about that last night (new Z1C owner, so sorry if I'm n00bish). I did the TA backup. Now, I could unlock the bootloader, flash a custom ROM and all the mods I want, then relock the bootloader and restore the DRM keys, and the camera would work as it should? (I wasn't sure to what extent the TA restoration would overwrite any changes made by a ROM.)
I'd love having 4K video and 120fps timeshift (tried the workaround for locked bootloaders and it didn't seem to take, unfortunately), but I resolved to sacrificing that because of the benefits of the DRM keys and my belief that you couldn't have both...

Again, as long as the ROM doesn't require a custom kernel you can do as you please.
So every ROM based on stok Sony for egz kitslim based on stock 108 and with based kernel in this case nut kernel

Hi all !
I've rooted my Play and looking forward to O/C it (mainly for N64 emulation ).
Reading several threads, I gathered that I need to unlock my bootloader and flash a custom kernel (DoomLord's for example).
My Play is not simlocked, so I can use the official unlocking for my bootloader.
If I understand well, I'll then lose some DRM-credentials... But I could not find exactly what that would mean. I guess there would be no problem with apps bought from the android market. But would I lose the games pre-installed on the play? Or the free games I got from EA (Dead Space, etc.) ??
Another n00b question: when flashing a custom kernel (keeping the stock rom), vill I lose everything on my phone and therefore, do I have to backup/restore everything? And if so, what would you recommand in order to have a full backup?
Thanks so much for your help !!

Drm is your your certificate for official updates and if you lose your drm official updates would brick your phone now, if you can't do a official update you can always flash using flash tool. You won't lose any of your games or the xperia store. There is a touch point method so you won't lose your drm. You won't lose any data from your rom when flashing a kernel. When do flash a kernel then you can do a full back up through cwm.

Unlocking the bootloader + flashing a custom kernel: must I backup everything before and restore afterwards, or do these operations keep everything intact (apps, datas, etc.) ??
Thanks for your kind help dan !
Yes that's the method and no you don't need to back your data up or anything when flashing a kernel. You only need to back your data up when installing custom roms.

Hi all,
Just got my Xperia S and really love the phone with fantastic design and awesome screen. I really intend to gain root access for my phone to troubleshoot the battery drain issue further (and using some app for better control over the setting). Here's a few queries I have (and some partially answered by some of my searches on the forum):
Will I get any OTA or official firmware update shall I just root my phone with locked bootloader? (I won't mess with custom recovery or ROM)
I suppose I could still claim my warranty. But is there anyway to remove any traces completely to prevent them from finding out? Just removing the superuser app?
If in the future I would like to have access to custom recovery so that I could flash ROM, I suppose I must unlock the bootloader right? (at least until someone gets a workaround for locked bootloader)
The tool I will use for rooting is by Bin4ry. I am on the latest ICS firmware.

Yes you'll definitely get official update
To remove trace completely just flash an official ROM via flashtool (official fw can be obtained at dev section)
No can install some stock based Custom Rom and CWM in locked bootloader
Eg : XTX,dualcore,Xcream,etc
What you can't do is flash a kernel. You'll need to flash a kernel to install Cyanogen Mod or Paranoid based rom

Hmm, I guess I could get official update, just worry that I would lose root during the update. I think I could still try to retain my root using some app right? (LOL, I am a bit outdated about all these stuff - was using a HTC Desire where 2.3 is the best we could go)
I am observing that my screen is a bit yellowish throughout, perhaps I will send in for a warranty before I do anything.
Thanks for the reply. Really appreciate it and clear off some doubts.
I've done some research in to unlocking the bootloader for my Xperia Arc. I have yet to understand the reason why you would need to unlock it at all.
The official definition given by Sony on their website is:
Unlocking the boot loader allows you to put custom ROMs on your device.
Click to expand...

However this is clearly not true. As I am able to put custom ROMs on my Xperia Arc without unlocking the bootloader (ie. I was on official ICS firmware. I flashed kernel to different version then root using doomlord's ICS root, flash back the original kernel then installing Ultimate HD 4.0 via recovery.)
I have noticed some other ROMs state they are for unlocked bootloader only. Is this becuase they require custom kernals in order to function? Is that why you need unlocked bootloader (because locked bootloaders can only accept official kernals during flash/boot)? Or is there a more in-depth reason?

To explain further, you can still install custom ROMs, but only ROMs based on stock firmware and using stock kernel. If you tried to install other ROMs like CyanogenMod you will realise that you can't install the ROM at all because you cannot flash the custom kernel that comes with it. What the unlocked bootloader does is allow you to install unsigned kernels onto your phone. Stock kernels are already signed by Sony so they can be flashed without unlocking your bootloader.
The kernels you have been flashing so far are all stock kernels so you can flash them with no issues. If you tried to flash a CM kernel you will get an error if your bootloader is locked.

Thanks. So I was right. The Kernel is (one of?) the reason you would want to unlock your bootloader.
Do you know if unlocked bootloader is required for SD partitioning on Xperia Arc? I had a read here http://forum.xda-developers.com/showthread.php?t=2126363 but something is confusing:
- Unlocked Bootloader (need EXT4 support, not allowed in stock kernel)
- EXT4 Kernel Support (most of kernels for Xperia 2011 have EXT4 support)

u dont really needed i payed 10 dollars to unlock it so i can use custom kernel to increase the performance of the phone,but still after 2 months after that i dont see any improvenments

Really? Went from Stock .587 rom to ultimate HD with stock .587 kernel and I find the phone can't handle more than 3 apps without slowing down at certain times.
I was actually considering unlocking so I can get an overclocked/custom kernel to improve performance.
What do you mean by after 2 months you don't see any improvements? Did the performance improve at first but now have gone back to similar performance of stock kernel?

If you don't know how to optimise the ROM then it will be as slow as any stock ROM. Don't say that the performance never improves after a certain time of usage. Please read up on the ways to optimize and improve ROM performance rather than assume that custom ROM is not good when you haven't tried optimizing it yet.

The base ROM is good, but it's the stock kernel giving the bad performance. Overclocking doesn't help much with performance so it's not recommended.
Like I said in my earlier reply, the ROM will work properly if you optimise it for performance, so don't say that the performance does not improve after a certain time of usage.

Correct me if I'm wrong but by saying "ROM will work properly if you optimise it for performance" do you mean flashing a custom kernel? (in which case you would need unlocked bootloader?)
Or do you mean an add-on like this: http://forum.xda-developers.com/showthread.php?t=1908269 ?
Or something else?
The only "optimizing" that u can do on a rom is removing the animations since overclocking is not recomenced.So i still find it useless.Even the phone app is starting slow.So in my opinion spenging money on unlocking ur bootloader is useless

So I tried "pimp my rom" and ticked all I thought I wanted but got a boot loop and had to reflash everything.
I'm keen to know what you mean by "optimising".

It can be as simple as installing and removing apps to running scripts that improve performance. I use Greenify to hibernate apps running in the background and I don't install Facebook on my phone. Only install apps that you use often because if you install many apps on your phone, it's going to take up more memory and slow it down.

Hi there, i managed to root my device a few days ago by downgrading, rooting and upgrading to .757 again.
Is it possible to delete apps, settings etc etc and fresh install .757 but keep Dual Recovery and root available without going through several downgrades and upgrades again? I have a locked bootloader and a backup of TA but would prefer to keep it locked if possible.
Ive been messing with root apps and installed something thats burning through my battery at double the usual rate and want to go back to a fresh copy of .757 rooted.
Also whats the easiest way to make whole backup of device once fresh installed again so can restore quickly to rooted .757?
Thanks for look.
Use this guide
http://forum.xda-developers.com/showthread.php?t=2688933
But dont uncheck wipe data on flashtool process for a fresh .757 install
p.s Personally i use titanium backup pal

If u have backup of TA then the easiest way will be unlock BL, flash 757 firmware, flash doomlord kernel with cwm recovery, root using cwm, flash dual recovery using cwm, flash stock kernel using flashtool and then restore TA.. It would be the easiest way and all the drm keys will be intact....

Sweet thanks guys, i used the tutorial posted and had it done in 5 minutes. I will be unlocking bootloader eventually but have not found a need to yet, is it really required for anything except custom kernels and cd drive emulation?
Ive also seen a few custom roms listed with stock kernel, modded with things like CM privacy guard and other tweaks and such. Can these roms be run on a locked bootloader if using stock kernel and will these roms still have the Sony DRM required features enabled if run on a locked bootloader?
Thanks again!
U will get the requirements about locked and unlocked bootloader in each rom thread

Hi All,
Now happy to share that my C6506 on LL 5.1.1 (10.7.A.0.222). One worry remaining is how to root it to get full Android power ?
I tried with kingo root beta and Kingroot (which i used to root 5.0.2) but no luck . I need this to install recovery/ xposed ....
Hope to hear good news from you, pals

If you have unlocked bootloader, simply download the superSU binaries to your phone and flash a KK custom kernel and flash the SuperSU bin via recovery. Or you can create a prerooted flashable zip with PRFCreator and flash it via recovery as well (which is what I did and root works correctly).

Stamina and Clear Sound work as usual. The only thing that doesn't work is the Bravia Engine. To restore that you'd need to restore the TA partition and relock the bootloader. (You can relock the bootloader without having to worry about breaking root or recovery).
Thank for confirm, will try soon.
Btw, it seems the 'cell standby' was fixed in this version.
Can i use the kernel in 5.0.2 in 5.1.1 in order to work the rooting process of kingroot?
@owlwood , Could you pls suggest some good custom kernel for ZL 5.1.1 ?
I don't think there will be a custom kernel for ZL. There has never been much development for this phone.
But we have a quite good stock firmware and we got Cyanogenmod, enough for me... :thumbup:
What special feature would you expect from a custom kernel?
There are no more development on ZL than Z that maid many custom rom in 5.1.
Hopefully they create now that z5 dumps are available ?
