Very weird root issue

When I first bought my ZL, I rooted the phone using binary4 V27 on superuser mode and that was very fast and simple. I could modify system files and do everything.
One day using my ultimate stupidness, I updated the firmware to 10.1.1.....253 then I did factory reset without doing a backup for my root.
Right now, when I go to settings -----> about ----> I get Kernal version 3.4.0 with android version 4.1.2 but unfortunately It seems like I don't have a rooted phone + I am unable to do any function of a rooted phone like modifying system files or ....etc .
I've tried million ways such as:
1- rooting the phone using the same method --------> the result is stucking at the wight screen and nothing happened.
2- Using motochopper method --------> doesn't work
3- Using the method of installing Android SDK and using the command prompt window to push (Su-busybox-superuser.apk) files to data/local/tmp/ --------> when reach sysrw step (sysrw not found)
tried to type SU (su not found)
tried to use one of the alternative commands like cd /system/usr/we-need-root or ./su-backup -----> file not found
or mount -o remount,rw '' /systemmount ---------> Operation not permitted
I will be following your instructions directly and give u the feed back
I am not gonna move anywhere until solving this issue BC I am getting crazy
I would highly appreciate your help guys , ... Thank you so much in advance

Ur bootloader is lock or unlock? If lock, you have to be patient for new root exploit method to appear.
Another way is to degrade ur Rom to. 434 and root. Then flash doomkernel v7 (this only apply to bootloader unlock) and flash .253 xcluding kernel. When finish once u want to reboot, there will be request to root appear.
Another another way, download rootkeeper, then temp un root and run OTA but some people in Z forum reported that it still fail to update, some successfully update.

Some aspects of modifying this phone can leave you a seriously broken phone, notably the TA partition. You would benefit greatly from doing a lot (like hours and hours) of reading in the "Z" section. All the activity is there, not in the ZL section. 99.9% of all the information there applies to the ZL (but practically NONE of the download files, so do not use software there unless clearly labeled for the ZL). The sections on backing up TA (look for DRM and TA), on using flashtool.
Note that all the information on root that does not specifically mention 253 is obsolete.

Thanks alot for your reply but I really don't understand why this device (ZL) is being ignored like that

[Q] The correct order of root

Hi,
I want to root my xperia z1 compact.
As i read, there are few steps that i need to take before rooting my device - backup TA partition, installing CWM, rooting the device.
Both of the CWM/TA backup require that the device will be rooted but if i will root my device without backing up the TA partition i cant go
back and reinstall the stock rom.
What is the correct order of the rooting process?
If the rooting process will get done correctly can i reinstall my stock rom back(for warranty issues)?
What are the downside for rooting - i want it mainly for Titanium backup and the Lba apps?
Thanks for any help!

If you follow the guide, you should be able to root without Unlocking Bootloader (Which will cause you loosing TA if you Unlock bootloader first)
So, the best way is to Root (Without unlock bootloader) which is in the guidance, then Backup TA, then you can unlock bootloader if you like (to install ROM or other tweaks).
For myself i just need root so i kept the Bootloader lock and have a backup TA just in case.

If i understood correctly, i will be flashing other rom(previous version in which the root witout unlooking bootloader exploit exsist), to my device.
what will be the effects on my device? will i lose my current device configurations - apps/settings/localization/...? where this change wil be noted?
The process is very complicated and with a lot of "Brick" possibilities, will a more noob friendly version should be expected soon?

Yes you will lose your data as stated in the guides. There isn't really any brick potential, if you screw something up you should always be able to start over again.
As long as there is no other exploit, there won't be an easier method.

Hi,
I've rooted my Z1C successfully 2 weeks ago with this guide: http://forum.xda-developers.com/showthread.php?t=2642081
At step 18 you had to do a factory reset... You should always create a backup. But you're are right, this guide could be more noob friendly
I wish there were some screenshots or more detailed explanations, because after I flashed the first file, I only could see a black screen, a white symbol photo of the Z1C with some japanese (?) characters and the phone doesn't do anything... Can't turn off, can't exit this screen... I was shocked until I see a home screen

Hi,
in my situation it would have been helpful to know following things:
- is it ok to rename the downloaded .ftf files from .zip to .ftf ? --> in my case it was ok, because the windows explorer automatically saves the .ftf file as .zip (also .apk files). --> in your guide, post #8, you wrote that this is not ok.
- as i already wrote in my last post, i thougt my phone got bricked after flashing the first file...
- i got stuck at step 13, installing dualrecovery and got the message "Waiting for device to connect" - in my case everything was configured right on my computer, already checked your tips, but it doesn't work until the fifth restart of my phone... maybe you should also suggest a few restarts when the phone would not be recognized
i've rooted several samsung and google nexus devices, but this phone...
but in general, your guide is really good and helped me!

Great :good:
I rooted and unlocked the bootloader right after I bought the phone so data loss was also not a problem for me.
Factory reset is located in Recovery Menu under 'Wipe data/factory reset'.
In the end you will have an unbranded UK firmware with root access. There isn't really any difference.

What do you mean there is no difference?
What are the diffrences between firmwares? what does firmware means- kernal maybe?
I need to understand if having the uk firmware will cahnge my current "device expereince" - gui, localization. preinstalled apps, or it is
just a change to the os itself without any imapct on the current user interface.

Pretty sure there is no difference in the kernel. There might be a difference in the pre-installed apps or modem, I don't know your current rom so I can't answer that. In the end you won't notice any difference.

Firmware is basically the OS, Gingerbread, Icecream Sandwich, Jellybean, Kitkat, and the main difference between a UK ROM and a Global ROM for example might only be one or two apps at the most.

Sony's UI looks the same on an ROM (that is the same Firmware), and if you need to flash a new ROM to root then chances are you will loose whatever you haven't backed up.

Thanks for your help so far...
The preinstall apps does not concern me - most of them i will remove anyway...
The modem part sounds problematic....
My build is 14.2.A.1.114, where can i found the rom/modem version data?

You don't need to care about that... Just follow the guide you won't notice anything different.
If you are scared so much you could create a ftf of your stock rom (there are guides on the forum).

Let summerize the procedure so far :
1. I will create a ftf image of my stock rom using the guide that i found, here :
http://forum.xda-developers.com/showthread.php?p=35910775
in the "How to backup your Sony Ericsson Xperia firmware using Update Service and the FlashTool" video.
In that guide the end result is a ftf file and the root guide asks for zip file, how can i get the zip file from the ftf one?
2. I will root my xz1c as the guide suggests here :
http://forum.xda-developers.com/showthread.php?t=2642081
3.ABOUT THAT I AM NOT TOO SURE : on step 19 on sub step 1, i will instal my device ftf instead of the uk one and continue
with the rest of the other 2 sub steps.
Am i correct?
If i am flashing back my device rom or the uk rom at the end of the procedure and both roms are unrooted, how come the device is rooted?
After rooting the device how can i unroot or reroot if needed - i will have to go all the way again?

No.. I meant that you can create a ftf of your stock rom if something would be wrong with the UK one you could flash your old one.
But this won't even happen because the ROMs are almost the same! I don't understand what you are scared about.
There are people from many countries using this UK firmware and no one complained yet.

Ok, so no going back....
After having my device rooted with the uk rom, how cam i localize(keyboard, lang, cell operators, etc....),
the device to my country?
And again with the logical question - if at the end of the process i am flashing an unrooted rom that i flashed at
the beginning of the guide, how can the device be rooted?
I have just been notified that my device is going to get updated to Android ver 4.4.2(KitKat) today/tomrrow, does it changes anything regarding the root procedure?

You just select your language in android, like you normally do
UK firmware does not mean there is only english. There are still all languages available.
In the end you are flashing a zip file (step 19.1), that zip file has root installed.
I am working on updating the guide for KitKat.

[Q] Installing ROM's [Xperia S]

So after a year and half with this phone, I thought about installing a better ROM.
I experience with these kind of things from the time I had the galaxy 1 and I changed tons of ROMs on that.
But the xperia seems a bit different with ROM changing.
What are some basic things I need to know, and where can I find the stock ROM (just in case)?
If this isn't the correct to forum for this post, please notify me.

ROM changing ist not very different from Samsung...
If your bootloader is unlocked and your CWM is working, then you can install all Roms as ZIP like on the Galaxy
Always make an Backup with CWM to be save and get back in case of errors, thereforce i didn't need a the stock ROM
Just have a look here on the last pages

thanks! But what I meant is that with my sgs I didn't need to open the bootloader and install CWM since it was already there.
How do I unlock the bootloader and install CWM, should I root it first?

Just have a closer look to the link mentioned above.
I postet there a link to a Guide, how to flash a custom rom (including unlocking Bootloader)
and Mirhawk gave aditional tipps
Have you bought your sgs secondhand?
Because you have to install CWM one time on your sgs, too.
And it is a similar effort to flash sgs with odin then unlocking your bootloader on the xperia S

Install ROM's in Xperia S is not difficult.​
You must have Rooted your phone and Install CWM (like the comment above)
I was like you when I decided flash ROMs.
I recommend you see if your bootloader is open or not (when you verificate it, you will see in the screen of your phone BOOTLOADER UNLOCK, and then YES or NO. bootloader is easy to open when you have YES, but when it's in not is a bit complicated)
To put the BOOTLOADER UNLOCK in YES, first: you have to have your phone free (your phone have to be available to use with others companies) in my case, for example, i dont have my phone free, but to liberate it with my company, give mea code and after that I introduce it and set free the phone. (after that you will allow to open BOOTLOADER)
Here in XDA have 2 types of ROMS, to LOCK and UNLOCK bootloader, I am using TrinityVengance RaptorXL by f(x)THaxxorX, before that I used, LeopardX 5.0 by savergigio
To flash ROMs you use ClockWorldMOd, its very easy, if you need more help tell me

Z5 premium stock upgrade

Hello guys,
New to this however I've done some things that I need explaining if they are able to :
I've flashed a stock rom back on the device (ftf file) using flash tool and now I've nicely got rid of some carrier stuff.
I didn't need to root / unlock boot loader, I can't anyway since its locked forever apparently, thanks to EE UK - why is this as I thought you need to unlock a device before you could flash it?
For those who are new to this I can provide links / limited assistance as I'm trying to process what I've done so far, but the reason for this post is if anyone has the Z5 premium nougat FTF stock that would be great!

You don't need root nor an unlocked bootloader to use flashtool and flash stock firmwares...to root though you need to unlock as you need to install a custom rootable kernel, but indeed not possible in your case as your carrier asked to lock your bootloader....
And Nougat is not officially out yet on the Z5p...so that is that!

Thank you so much!!!
since i bought this phone everyone told me i must unlock bootloader to flash new stock rom !!
even though i never unlocked it in my z1 compact (r.i.p)!!

Not a necessity, but those roms make changes to system which can't be done without a custom kernel, so you'll have to unlock your bootloader...(which is not possible in your case)

Yes just flash latest 7.1 bullhead image and then relock bootloader and you will have your device like stock but why would you downgrade?!

Sorry to answer hours after but I didn't got any notifications...
So, download,
platform tools : https://developer.android.com/studio/releases/platform-tools
Latest 7.1.2 build : https://dl.google.com/dl/android/aosp/bullhead-n2g48c-factory-45d442a2.zip
Then exctract the content of the 7.1.2 build in the platform tools folder then connect you smartphone to your PC in bootloader mode (vol down + power button).
Finally in the platform tools folder you will find a file named flashall.bat, simply execute it and you are done, your device will be on stock 7.1.2
PS: This guide was done assuming you know how to lock and unlock your bootloader if not...tell me ? (kidding happy to help ? ).

Thanks a lot for the guidance!
Unfortunately, I don't know how to unlock and lock the bootloader. I 've never done this before and always had my device stock. Any advice would be helpful!
Thanks

NOTE : unlocking bootloader will erase all your data!!!
NOTE 2 : If you lock your bootloader without the factory image flashed you will brick your device so no more usable!!!!! So personnaly I don't recommand you to do that because you don't need that to return on Android 7 it's just a "security" for your data.
NOTE 3 : read this guide too because it's more complete and what you are going to do is a bit risky(I speak for locking bootloader) , really! Don't want a message saying "you forgot this line, my device is lost ? ...".
So let's start fun things ?
Go in developer options and enable oem unlock and USB debugging.
Then reboot in bootloader mode and connect your device to your computer.
After that open the prompt command from the extracted platform tools folder by right clicking in this folder with the maj key down.
In this command windows write the following line:
fastboot oem unlock
Or .\fastboot oem unlock if your are on windows 10 (windows is blue instead of black).
When the bootloader is unlocked you can flash a custom recovery then instal a ROM/kernel or flash the factory image.
When you have flashed the factory image (stock ROM...) you can lock the bootloader with this line(same method)
fastboot oem lock (add .\ for windows 10).
Tell me if you need further help ? .

Thanks again!
I have to lock the bootloader if I downgrade because bank apps don't work if the device is not stock as far as I know..
other than that I don't mind to be unlocked and playing with custom roms..

That's actually not true, at least I think as I don't use bank apps that don't accept that my bank app is accepting root too ?
But seriously, from where did you catch the info?

I have read comments from developers to advice users whose apps are not functional that the devices should not be rooted and generally should be stock.
Anyways..I will think it again if I continue to the procedure..
PS: I hate the layout of oreo..these white (like LG) squared app icons are simply terrible!

Android layout can be changed easily and having latest Android security offer security and latest features and performances patchs, anyway it's your decision.

Just keep in mind that unlocking the bootloader and flashing the original rom will NOT result in a rooted phone. If you do the this and relock the bootloader, then your phone will be in a totally stock NON ROOTED state. So any concerns that you have regarding root don't apply here.

I am still on 7.1.2 too because of the performance/lag issues in 8.1
... I never upgraded... Is it still really that bad in 8.1 ? Or better with latest patches?

Hi,
my device got bootlooped. Warranty expired 20 days ago and the cost was too high to repair.
So, I followed an online tutorial, flashed my phone and came back to life.
The issue is that the bootloader is unlocked and I cannot use android pay (it says that the device is somehow altered)
Although banking apps work normally.
Is it ok to relock the bootloader?
(what if the device get bootloop again? / is it possible to brick my device? / could I use another way to bypass and activate android pay?)
Thanks

Firstly let me tell you that I am assuming that you have flashed an official stock rom, if you didn't then just ignore what I am saying!
I never heard of anyone bricking the device just by locking the bootlader. The worst thing that can happen is to get a bootloop indeed, but if you just unlock the bootloader again then it should be fixed. Bricking the device just by locking the bootloader sounds totally impossible to me at least. I don't know if there is another way to bypass this and activate android pay but even if there is personally I will not have trusted it.
