[Q] Need help rooting!

Hey everyone,
Just to let everyone know I am a noob, however I did watch a lot of tutorials on how to root the Xperia ZL. I am referring to this post: http://forum.xda-developers.com/showthread.php?p=31545627 However, considering I am a noob, i can't post in that thread. I am experiencing some problems when the Bat file won't push the Super User app and Busy Box to the phone. Are there other approved methods of rooting this phone. By the way I have a locked bootloader, and I do not plan on unlocking it. Very afraid of screwing something help.
Thanks.
Just to add, I am using v30 of Binary, and everything works fine until I get passed the "restore option." After I complete this and am told to go into "Service Tests- then Display" this is where nothing is happening, and I am waiting forever!

You can use the new flashtool (Flashtool version 0.9.10.2beta6) to root your new XZL. It's the easiest way to root XZL.

Yes, you still can root without unlocking ur bootloader.
Using flashtool u even can relock ur bootloader after u had unlocked it.
One tip after u rooted ur phone, please do a full backup including ur TA (this will ensure u still have ur drm key for bravia engine) incase you want to try to flash other rom especially AOSP base rom and getting back to factory default rom.

One question if i unlock bootloader and again lock it. Is my warranty lost or?

Basically, yes ur warranty is void if u unlock the bootloader because u need serial key to unlock the bootloader which u can get it by requesting from Sony website (u have to give ur phone imei number to get the serial key, Sony may blacklist ur imei number).
But if u can make it totally stock after u relock the bootloader (including ur drm key, this key is unique u can't flash others TA in ur phone, it will brick ur phone), and consider u r lucky (the Sony technician may not check the blacklisted list), u may claim the warranty.
This is only my logical thinking, u may need to validate my statement with others. I do not know whether Sony blacklist the phone imei if u request the unlock key. FYI, HTC blacklist the phone imei once u request the unlock key.

As far as I know you can't get back the drm key if you're not backup ur TA first before unlocking the bootloader. U may try to ask the owner of the phone, he/she may have the TA backup but even if he/she have it, I don't know whether you know that TA is belong to ur phone or not. I do not know how to check that, it may have imei number in the file to validate.
Please correct me if I'm wrong.

An you are talking to a complete noob, so I do apologize, but TA? I understand I need to do a full back up of everything, I have done that before on other phones I have rooted. Just use Titanium backup for this, or is there a better app to conduct full backups. I haven't rooted phones in awhile. I had a couple Galaxy's notes and stuff that I rooted but I never did back-ups because I was just using them temporarily. So i've been out of the loop

Please refer this link to backup your TA http://forum.xda-developers.com/showthread.php?t=2234627
For full backup, i think you need CWM or TWRP recovery with stock kernel, please refer here http://forum.xda-developers.com/forumdisplay.php?f=2095
If you are very new to this, I advise you to read and understand completely before you start anything. If you want to install hacked games or tweak a system a bit better you just root without unlocking bootloader, if you want to taste AOSP based rom or addicted with ROM flashing unlocking bootloader will ease your job.
Good luck with your reading and happy rooting

The best method to rooting your Xperia ZL is this method I did to unlock my ZL phones, the easiest without unlocking the bootloader believe me.

Help to lock BL & unroot & install stock?

Please can someone advise or point me in the right direction to lock my boot loader. Unroot and flash back to stock please.
Thanks in advance for any insight :thumbup:

Resource thread has everything you need.

I hope you have a backup of the TA partition. Otherwise it's impossible to relock the bootloader
if you have a backup though, then read here:

Oh dear I don't believe I have the TA backup.
What's my best option to get this device looking and feeling as stock as possible..... And what implications to usability does the lack of TA restore mean? Will it prevent OTA updates
Thank you so much for the insight I didn't even consider TA when rooting. Damn

You loose a few features like mirror link...
"Certain pre-loaded content on your device may also be inaccessible due to the removal of DRM security keys. The secure user data partition may also become inaccessible, and you will not be able to get any more official software upgrades if you unlock the boot loader."

Can I flash this stock ftf for my country (using flash tools I believe) straight from my current set up with twrp & PAC ROM?
Will the ftf also flash back the stock recovery?
Thanks again

Yes you can flash the ftf directly, and here's what you'll get:
A stock ROM
unrooted
Lose some features related to DRM keys
No OTA
Stock recovery, which is none as far as i know
This is as close as you'll get to making your device feel locked.

Thanks again for the information.
Will give this a shot really soon :thumbup:

Hmmm you're right, one can still relock the bootloader, but the TA partition along with the drm keys will still be missing, which will render the relocking kinda useless.
Better said, I don't understand the reason behind relocking if you're not getting the things you lost back.
@dillalade
If you still want to do it, then here's a link showing how to relock from doomlord, so it's pretty reliable

I am guessing that OP wants to return his phone. If he is lucky, they will simply check the rooting status in the service menu and not if DRM keys exist.

Thank you everyone for the input.
If I do Relock the BL will it grant the device OTA updates or is that again TA/DRM reliant?
I just sold the phone on eBay for £200 so want to get it back to stock before I send it out tomorrow.
(Awaiting receipt of a pre ordered Z3c... there had been a significant price drop from £450 down to £350... So £150 for an upgrade seemed fair. )

You should get OTA updates if you relock bootloader. I've never tried but at least Sony PC Companian does not complain anymore about a modified device. I hope you informed the buyer that the device was actually unlocked though.

Yes the buyer is aware of the phone being previously rooted.
Is it normal for Sony stock ftf rom to have empty APN settings.... if I remember correctly this was also the case when I originally purchased the phone.
Thanks for everything guys

Are they aware the bootloader has been unlocked so might not be able to do what they might be buying it for.

the APN settings get generated depending on the current service provider (currently inserted SIM card). Even then it might be the case that there are no pre-registered APN settings for that provider.
I wouldn't worry about it much

try flashing your official firmware through Odin. other users solve their imei problem by doing that. see also if you can access engineering mode with that official firmware.

lets wait for others specially those who are expert in android for some advice. I'm just an ordinary security guard so i can't help you much with your problem. what i have suggested you from my previous post was the last thing I did when my phone finally worked. for 4 days i been searching for solution because i also have an IMEI problem. i flash back to official rom, flash patched modem, flash other roms to no avail until such time when my phone doesn't boot because of broken partition :laugh:. if you still have warranty restore it back. if you're already out of warranty and you have money, you can it send it to service center.
P.S.
you can also try this if you have courage. i was able to make some secret codes work but i have'nt tried if it works with engineering mode by modifying hiddenmenu in /efs/carrier/hiddenmenu. use efs explorer to open hiddenmenu and change it to ON.save it and restart your phone and see if engineering mode work. remember that you have to be in official firmware and also rooted to do this. if its not working then you'll just have to wait for a much better solutions from devs.

Same question
I have the same problem, as owner of the thread. Any help?

[Q] Restore Z1 Compact to stock firmware before sending it for warranty repair.. help

Hello XDA!
I've ran into some hardware related issues with my Z1 compact (the earphone jack is glitchy) and i want to send my phone in for repairs.
The thing is i have a modded cyanogenmod firmware on it as i preferred it over the stock rom. I also have that clockword mod thing.
As you can tell i'm not very accostumed to doing these things and i was wondering if anyone would guide me on how to restore the phone to its original stock setting?
The phone is a swedish device so i would need the scandinavian versions i'm guessing, any ideas out there?
Thanks.

You just need to find the right firmware for your region / provider.
I would recommend IaguCool's thread on Xperia Firmware Downloader & Checker, if you have flashtool installed you can make your own ftf that is exactly right for your phone. All the instructions are in the thread.
Hopefully you made a copy of your TA partition before you unlocked it and put CM on your phone? it may not matter if you have not, as long as it looks stock.

Hey digesteve,
Thanks, i'll check that tool out. I don't know if i made any backups of my TA partition, but probably no because i don't know about it.
Is there a way to see if i made a backup of the TA partition, could it be stored somewhere on the phone after installing clockwork mod?
Thanks for the help!

If you didn't do it, then it won't be saved anywhere on the phone. You have to physically copy it to the hard drive of your pc for safekeeping.
It doesn't matter, it won't stop you from restoring the stock rom and I don't think not having it voids the warranty. Maybe somebody could correct me on that?

Definitely didn't do it then. Hopefully they won't give me any trouble for rooting it, it's worth a shot anyway.
I've downloaded the firmware but it doesn't come in the same sort of package as cyanogenmod, are there any guides you can recommend on how to apply this firmware to the phone?

and don´t forget to relock the bootloader with flashtool!

You'll need a copy of flashtool and the adb drivers.
Flashtool will turn the downloaded files into a tft file, but all the instructions are in the thread.
If you get lost then XperienceD's AIO thread will guide you in the right direction

I downloaded flashtool from sonys website and it actually listed stock firmwares in a list which i could apply to my phone so i did.
Now the phone boots into what seems to the be stock firmware, however i was going to go into recovery just to check that was restored too and not the clockworkmod i had previously installed but it seems i cannot boot to recovery anymore, what can i do? Where can i find the "stock recovery" that these phones comes with? I want the phone to seem as it was never rooted/changed on the software level

You have flashed the Sony rom, so now it is stock, with no root or recovery. There isn't a stock recovery. Your work is done.

Isn't there a menu you can boot to that gives you the option to wipe cache partition and do some various other stuff? Perhaps this is only for samsung devices, sorry for the confusion and thanks for the help!
Hopefully the service goes as planned!

Is still the way to do it or is there any new ways ?? I have bought a Z1 Compact for my son who is 8 and he wants it back to stock. It has CyanogenMod now.....cant recall what version though since i dont have the phone with me.

Did you checked weather your Bootloader is unlocked? If not then check it.
Also try to repair your phone through PC companion.
Its a strange problem. Hearing it first time.
Did you followed exact procedure of the Guide that I linked?
I don't think it occurs due to heavy flashing of ROMs, because I have used every ROM available for the phone for almost 100 times. I usually change my ROM after a month.

The problem occurred when the user try to flash back to stock ROM from Custom ROM.
The Bootloader is unlocked.
Now the BL appear to be like this: Bootloader Unlock Allowed = No (*#*#7378423#*#*)
Enter fastboot fail (No fastboot detected), Only Flash is allowed.
To install CWM or TWRP required fastboot, so I can't do anything besides keep trying to flash wiith different version of stock FTF.
Solution I tried but failed:
- Fix using Sony PC Companion (PCC)
- Flash any version of stock ROM, inclusive of just flashed the "Baseband" only.
- Flash Acro-HD S0-03D ROM then flash back to stock ROM.
- *#*#4636#*#* -> Phone information -> Set preferred network type (any of the option & reboot)
- Settings -> More -> Mobile Networks -> Network Mode(any option & reboot)
- Settings -> More -> Mobile Networks -> Select providers (automatic or manual), it manage to detects the service providers but registered on the network failed.
- Insert other active SIM Card
I try to locate the Antenna Board but it seems like it was attached with the mainboard. Unlike Xperia Z, the Antenna Board is seperated.
I assume this problem occurred when the partition accidentally bricked by Flashtool? I did try to flash different version of Baseband, nothing seems work.
I need someone favors. Create a Pre-rooted Stock ROM(.ftf) with Recovery Accessed (CWM or TWRP).
I found somewhere from this forum stated that tried to install back any of the Custom ROM to fix the No Signal Issue which it appeared to be my last hope. Without Recovery(Required Fastboot to install), I couldn't install any custom ROM.

First of all let me clear that 'Unlocking Bootloader Allowed = No'
That means you cannot unlock it unless your coming to stock from other ROM.
Also Bootloader can be unlocked only once. So if your coming back to stock from custom, why did you tried to unlock your BL again?
Even if you flash stock ftf, you no need to unlock your BL again.
Secondly, don't try to flash other ROMs into your phone, you could mess up everything, even hard brick.
Your Fastboot mode isn't working, right? If so, then try to install fastboot drivers from flashtool driver pack. Maybe it could work.

I did not lock my BL, it just lock back by themselves. I still remember I unlock my BL with Sony Official way in 2013. After that, I did not touch that BL again. It's just after the recent flash which I did the same way like before(Custom to stock ROM), everything mess up.

My very last but not recommended solution is to change the motherboard. However, looking at the posting not only me having the issue and it mostly happened when users are flashing back from Custom ROMS to Stock ROMS.
Changing motherboard is like changing another phone, your feeling towards the phone changed.

After flashing stock ftf, the BL status always shows 'Bootloader Unlock Allowed = No' but it is actually unlocked. So it does not get relock after flashing stock ftf.
It seems like a serious problem.
Maybe, flashing other ROM will help you a bit. For that Obviously your phone must enter into fastboot mode (which is not happening). In this case did you use 'dd' command for installing recovery? If not then you could try it. And I think you'll be succeeded to install recovery and further you can flash ROM.zip through recovery.
You just need to copy recovery.img into your internal memory and enter some command's using adb shell.

I did not lock my BL, it just lock back by themselves. I still remember I unlock my BL with Sony Official way in 2013. After that, I did not touch that BL again. It's just after the recent flash which I did the same way like before(Custom to stock ROM), everything mess up.
I even format my pc which I thought it was my pc issue earlier. But ends up I realize it was something regarding to my BL. With BL Unlock Allowed: No, you cannot enter to your bootloader or fastboot.
This video is showing exactly my problem now:

You must have used a newer version of flashtool. This is causing similar issues for many people. The only solution for now seems going to Sony service center. There is another method too, flashing the TA backup, but I don''t know if it works or not.

YES, I am flashing with NEWEST VERSION of Flashtool. After that, the result turned nagative.
Do you mean TA Partition? Do you have a backup copy of it?

Latest UPDATE about the issue, PLEASE TAKE NOTE BECAUSE YOU'RE ABOUT TO BRICK YOUR PHONE JUST LIKE ME. THIS IS IMPORTANT!
@hitman-xda , Please pass this message around. Btw, How to quote the name?
If everyone here in this post flashed their phones with Flashtool 0.9.19.x version, then congrats my friends, we're all become owners of bricked phones with no network signal. Flashtool 0.9.19.x versions have sript error which replaces original Ta partition leading to unlocked bootloader to become locked and loss of network signal. If you're guys haven't backuped your Ta partition prior to bootloader unlocking then that's all.

Flashing with latest flashtool flashes a partition which renders modem of the phone useless. Yes, I mean the TA partition. Each phone's TA partition is unique, so if You flash mine or other person's TA partition, Your phone would not even boot.

This is toooooooooooooooooooooooooooo OVER! It means my phone is bricked forever.
It's their mistake but we have to bear it on our owns.

Yes, nothing worked because Flashtool just accidentally bricked our Sony in the whole world. A careless mistake destroy the phone.
In 0.9.18.X, simlock.ta is always excluded by default but a careless mistake on the version 0.9.19.(1234) (at that time), The Simlock.ta is included while flashing. Each phone TA has their own unique number. Besides changing the mianboard (the only solution right now), no ones manage to solve this issue.
I wonder how many Sony phone in the world has already been bricked by this Flashtool update.

On 0.9.18.X, even if simlock is included, it is excluded from flashing
On 0.9.19.5 I did this way :
- simlock is excluded by default with a warning when including it (unticking button)
- When simlock is included, when flashing, a YES/NO box appears asking if you are absolutely sure you want to flash this unit.
- When creating bundles, simlock can be included (no risk with 0.9.18 as it is always ignored)
So if you have a TA backup, with 0.9.19.5 you can restore the 07DA unit (then reactivating the phone). Thing you cannot do with any previous release as 07DA unit is hardcoded_excluded.
I will publish another patch that will backup any TA unit that is about to be flashed. That way there will always be a solution to come back to the previous state.
simlock, if present, is always ignored in 0.9.18 release
simlock, if present is excluded by default with the ability to include it with a warning and a user query before flashing the unit
people who had issues are ones using ftf bundles created prior to 0.9.18 with simlock included. Never had issues on 0.9.18 as it is excluded by default, I forget to keep this exclusion on 0.9.19.[1234] and added a defautl exclusion on .5 with the ability to include it anyway.
But maybe it is not the right way ... I was asking myself when I did it. I want to give the ability to restore 07DA unit if ever a backup exists
The only way to recover from locked phones is to reactivate them in a service center or to restore the 07DA unit.

Well, that is disappointing
Hard to believe, that Sony really did that serious change in its software.

At least you're out of trouble. I suggest you need to backup your TA Partition just in case.
Each TA is unique and cannot be transferred.
If your TA is used by 3rd party, they may face a Hard Brick & cannot be recovered anymore.
Well, this is an added Security by Sony. They are not stupid to "share" openly for free.
Now I'm realize.

That's bad but still not too late. Your next Sony in future will be secured
I'm already ordered the replacement mainboard.
What kind of mainboard-Lock BL or Unlock BL, I do not know because it's not a new one.
Waiting for shipment.
