[FIX] Enable FOTA update for UNLOCKED bootloaders WITHOUT brick - Xperia Arc General

Hello pals
Well I have a kind of good news
All of you know about the FOTA update problems when your bootloader is unlocked. Well forget about it.
Simple as that, FOTA brick is past.
Now is possible to unlock bootloader and even repair the already unlocked ones to be able to update via FOTA.
So if you have this problem and you want to fix it you know what to do. (Send me a PM)
This process have no cost but if you want to buy me some Dr. Pepper you can donate

You will need to download this: Download Me
And also a paperclip or wire will be needed.

No need to unlock for repair already unlocked phones
So it does NOT require credits

Ok, video is up and working

We did this yesterday and it worked brilliant.
took just a few minutes.
Another great job done by Alejandrissimo.
rooted update worked without complications.
thank you very much

Update!
Users with phones unlocked by omnius/others-tools can NOT use this fix without re-unlock the phone.
I think is caused by different signature certs

Hello
Just to see if I got it right.
I unlock my mk16i using the code provided by Sony. Now i can't update using PC companion or SEUS, because they both say, I've got modified software installed.
Will this fix this isue and allow me to install the upgrades directly from Sony?

Can't update
I can't update my Neo V MT11i......it says "Your phone contains modified software" while i update through Update Service .....what to do any suggetion?

hi guys is there a way to find out what the original network lock for the phone is...for example if it is originally on o2 before it was unlock. and how can i tell if it was unlocked via setool? when i bought the phone it was already unlocked.

So practically now if I flash for example .42 firmware with my bootloader unlocked and search for updates and get notified about .62 firmware, OTA Update it, when the new firmware is installed, my phone won't brick anymore? Or I have to patch it or fix it with this tool? I mean did Sony fixed their firmwares to work on unlocked bootloaders too?

great promises and dead links.
I hope the guy made trillons in donations.
would have been useful to tell others a lil bit how this worked and whether other models can do similar things.
but no, the secret went down togther with the op's website

[Q] A quick question.

I recently obtained an Xperia Play for myself from Verizon. I was wondering if any of you think I should root it or not. I have rooted my old Droid1 and have flashed a few roms on it. I am just finicky about doing this phone since it is brand new to me and the bootloader was just unlocked recently. I don't really want to brick my phone (I'm quite sure no one does.)

how can your brick your phone rooting if anything you have done the only risky thing unlocking your bootloader
No, I haven't done anything with it yet.

you said in your op that "the bootloader was just unlocked recently"
What I meant was that the verizon model was successfully unlocked, not that I had unlocked mine.
So to clarify, I will have to unlock my bootloader in order to obtain root for my Verizon R800x? Also, it will brick if I use an OTA update while it is unlocked? If this is so is it possible to relock the bootloader in order to avoid bricking it? I want to make sure I know as much as I can before attempting to root my play.

1. Yes
2. Yes, any official updates (Pc companion, OTA, SEUS) will brick your phone
3. Yes. http://forum.xda-developers.com/showthread.php?t=1134334&page=5, But i dont know if it works on the r800x. I think blagus is waiting for someone to test it. Ask on that thread if its working or not. In the case on the r800i you can relock the bootloader from the link above and then use offical updates again.
Tbh you might get more info if you check out the R800X Bootloader CRACKED! thread
Okay, thank you a ton. I have been reading a lot of these forums lately and haven't found a clear answer for my questions until now. I was reading that blagus is waiting for someone to test it but the last post is from the 8th. Now I just play the waiting game.

[Q] Super noob needs a help here!

Back in old days when i had a HTC Wildfire with a few clicks i rooted it and started installing new ROMS on to it
But since i got this New Xperia Play : R800i Build NO. 3.0.1.a.0.146 {UK}
I got no clue how to do anything on it. Let me be honest here... I updated my phone using the option under the settings menu in About my phone and seems to be on 2.3.3 and look all my friends have rooted their phones but i got no clue if its even possible . Mabey im not such a noob or something but i would be really greatfull if anyoen could point me atleast to the right direction. Mabey some helpfull links to help a fellow noob

Mine was from vodafone and wasnt sim locked either. Ok you have two choices for root. You can either unlock your bootloader (there are many downsides and advantages to this so you should research it) or downgrade to 2.3.2, root using gingerbreak then OTA update to latest version. That way you will not loose root while updating.

Im on my phone so i can't really link. Look in the android development section, there is a thread all about rooting 2.3.3 with a locked bootloader. OTA means over the air. Basically thats when you download and install an update using just your phone.

No you need an unlocked bootloader to flash custom roms. But please read the pros and cons of unlocking your bootloader first. And understand what you can and can't do
Sent from my R800i using Tapatalk
Ok mate just wanna say thanks a lot for your help and i really appreciate it. You really helped me out here. also just one more thing i need to know. By the looks of it the only cons in unlocking your bootloader seems to be that you will lose warranty and that your phone or your radio may get bricked which apparently can be fixed with restoring a backed up data using a program named omnius for se which i'm actually working on... however my only other concern is if there are any other disadvantages regarding the unblocking the bootloader that you happned to know of and be kind to share it with me Also just wanna say that i can see many tutorials as you said in the development section and i quite frankly i don't know which one applies to me since i realized one of the tutorials are for models with build number .184 where as mine is 3.0.1.a.0.145 AND I HAVE NO CLUE WHICH TUTORIAL TO FOLLOW. So i would be greatfull if you could lend me link to a right tutorial whenever you get free time on the PC
If all you want is root you can do that with a locked bootloader. You will have to downgrade to 2.3.2 (.184) then root then ota to get the latest firmware rooted. Follow the guide here. Or see this post i made here for easier instuctions on downgrading and rooting.
If you want to flash custom roms then you do need an unlocked bootloader like AndroHero has said. You dont need a specific guide to unlock your bootloader. Just go too the SE bootloader unlocking site (it gives you all the instructions you need) http://unlockbootloader.sonyericsson.com/. Then just flash doomlords kernel (which autoroots) or anything really from the development section (since i think anything can be rooted with one click with an unlocked bootloader) you will then have root and the ability to flash cutom roms.
Oh btw build number .184 = 2.3.2, build number 3.0.1.a.0.145 = 2.3.3 and build number 4.0.a = 2.3.3 (xloud version, the latest update)
+
If you unlock your bootloader OTA, Pc Companion + SEUS are off limits use any of them after unlocking your bootloader and you will brick your phone. Go to the dev section for the latest updates.

Question in wrong place

If i testpoint unlock my bootooader, apply root, change build.prop values to LT18, relock bootloader, restart phone, update via pc companion
Will this work for my arc ?

Since Track ID is freely available on the Market now for *any* phone does it make any difference if one unlocks the bootloader...?
Yeh, of course. Just wondering if this method will work..

If you unlock your bootloader for free on the Sony website you lose all your DRM licences and thus cannot use the stock TrackID version. You also will not be able to update via SEUS. Therefore, dont follow this path.
On the other hand, if you unlock your bootloader using the testpoint procedure, you keep your DRM keys, you can still update via SEUS. As an added bonus, it also removes the SIMlock from your phone so you can then use any SIM from any service provider from any country in the world.
The catch here is that you have to pay for it but at 15GBP it is not a lot of money. I have done it and also many other users on this forums. JINX13 does it remotely for you. Drop him a PM. Also, have a look at his webpage.
http://phoneunlockserver.com/forum/index.php?/topic/7-guide-all-xperia-bootloader-unlock-unlock-sim-enable-fastboot/
If you search on google you can get all the tools you need and do it yourself and not have to pay... just saying... I did it. Not that hard.

Interesting idea. I'd already flashed ICS the other day but am back on GB for the time being so thought I'd give it a shot.
Short answer is no, it doesn't work. Changed all my model numbers in build.prop to LT18i and customisation numbers to one on the list. Problem being, PC Companion still sees the phone as an LT15.
Good challenge though - any ideas anyone?
PS - I don't want suggestions on other ways of getting ICS, I can already do that! More interested in knowing where PC Companion takes the model number from.

I am trying to repair via PCC (hoping it will solve my persistent wifi issue)but always getting an error in the preparing step..can someone help me?Is it due to some authentication with the Sale ID or country or region and incompatibility with the official Nordic ICS?

You can update your Z3 even after you unlocked bootloader and rooted!

Hi guys
I don't know if this is common sense, but when I asked here, I was told my device would be bricked (can't update to newer software when they arrives like Android L). So this might not be helpful to a lot, but it is to me and might be to new people who seek info on their new device and still want to make sure they can update.
I just wrote to customer support and asked if their was any way to update my device with an unlocked bootloader. They told me that I can't update from phone, neither from PC companion. But was told I was still able to download Flashtool and update my device from there.
So hope I helped someone to make sure it works!
When ur phone is bricked u cant update, only thing u can do is to give it to your dog to play with.
But its right with unlocked bootloader u can update via flash, cwm ect which u should do anyway or what would be the reason to unlock it.
IThe only thing u loose is the sony stock stuff like camera app and some more havent had time to read about.
Google the word brick btw

As I understand it you lose your DRM keys. Those keys are unrecoverable and reduces your camera in darkness and audio.

Xperia Z4/Z3+ Root Discussion

There appears to be no discussion thread about root for the Z4/Z3+, so I thought one was in order.
I'm currently about as useful as a snooze button on a smoke alarm in terms of obtaining root. I'm curious - is there any development going on to root our devices? I'd love to donate and what not to possibly speed it up.
Let's talk!
BL unlock is not listing this device on Sony open devices
Flashtool from androxyde doesn't have the device listed as well, so I doubt BL could be unlocked.
Regarding development
I managed to unpack the blog_fs FILE'S from Emma so there we have the kernel.sin maybe we could unpack it with Android image kitchen, but I didn't succeed, Android magic was missing or something like that!?
If that could be possible, then we could repack twrp radish with zimage of the kernel.sin and perhaps have a working recovery maybe as FOTAkernel.
But that's just wishful thinking
First we need unlocked BL
And then we also have all the loss of DRM keys. TA partition and all that also needs to be in place, unless we're willing sacrifice a bit hehe...

You can unlock your device by chosing Z3... No need for Z4/Z3+ on Sony Unlock page.

Even with a bootloader unlock, is there any custom recovery for the Z3+?
Sent from my Xperia Z3+ E6553
Did any one try to unlock their Sony Xperia Z+ yet? Or any one try to see if it is unlockable by following steps.
You can check if it is possible to unlock the boot loader of your device in the service menu by following the steps below:In your device, open the dialler and enter*#*#7378423#*#**to access the service menu.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.
I am going to build a custom recovery incase the bootloader unlock allow says Yes..
Update: Yes it is allow to unlock the bootloader. I am waiting for my device then start working

By right if the bootloader unlock is stated as not allowed, you can only root your phone through an exploit. Other xperia phones exploits have been found (like my previous z2, i rooted it without unlocking the bootloader), I most certainly do hope one can be found for z3+ as it would allow all the DRM stuff to be backed up and its "neater" imo.
Otherwise, if no exploit is found, then no, you would not be able to root without unlocked the bootloader to install a custom rom.
However please check if you signed in to myXperia service. If you did, you just need to sign out and reboot, then your status would be back to allowed. That is only if originally the bootloader is allowed to be unlocked.

At this point, I see no mention of anyone working on any sort of exploit for the Z3+, this is a bit disheartening! I'm considering the new OnePlus device at this point since I'm sure root will not be an issue for that phone. It'd be a shame if it came to that since I love the feel of the Z3+

Did you activate your MyXperia app? If so, this could result in your phone indicating that the bootloader is not unlockable, even though it actually is. If you didn't activate this app and it still says no, then yes, it's not unlockable and you will not be able to install custom kernels / ROMs. Note that custom recovery can still work on rooted phones with locked bootloaders.

i looked into my applications and did not see a myxperia app. Just xperia lounge. I did install the current firmware using sony pc companion.
I am new to xperia. I had htc one and google nexus phones prior to this that I have rooted and such. I am experience but not in xperia. Any suggestions for rooting that you know works>
uhm where is this myXperia app you guys are talking about? I searched the app store and the phone and cannot find it. Under settings, there is a "Xperia Connectivity" section, but no option to sing out.
Googling the app did give some results and I did land on this page, which I was logged into. I logged out and rebooted the phone, still says "No" to unlock bootloader.
