[Solved] Roll back to 4.0.4?

Well... I have searched and searched and I just can´t find the correct answers to my questions...
Here it is:
My sons Xperia J is network-locked to 3 Sweden. It has a locked bootloader and it can´t be unlocked. The phone is upgraded to 4.1.2...
The only guide I have found for rooting is this: http://forum.xda-developers.com/showthread.php?t=2181640
It says that I have to be on rooted 7.5 FW to get 4.1.2 rooted. As I understand I have to downgrade first to get rooted... but how? Can anyone please give me a hint how to do this and to get hold of the FW needed?
My status:
Model ST26i
Android 4.1.2
Kernel 3.4.0
Version 11.2.A.0.21

You need to download flashtool from here: http://androxyde.github.com/index.html?1363522362000
then 7.5 ics firmware here: http://forum.xda-developers.com/showthread.php?t=2150578 then root it with unlockroot
then install clockworkmod recovery here: http://forum.xda-developers.com/showthread.php?t=2003069 install 6.1 for j NOTE there is no CWM for jb with locked bootloader yet. Then follow the tutorial for root jb for locked bootloader.

Allright!
If I´m supposed to use Flashtool, can I use this instead? I still want to use 4.1.2 but with root so I can modify and delete bloatware...
http://forum.xda-developers.com/showthread.php?t=2181640
Is it the *.ftf i´m supposed to flash? It´s the prerooted 4.1.2 I really don´t need CWM for my purposes

the ftf is the kernel and things the cwm zip is the rom you need it all! so follow the entire tutorial

Ahhh... NOW I got it!
I´ll give it a try tomorrow... I´m working until 10pm
Thanx for the directions!

I really need to be 100% clear of what I´m doing...
I´m in the process to download everything right now.
1: I make sure flashtool works with drivers and so on
2: I install (flash) the 7.5 firmware with flashtool? Just like that?
3: I root the 7.5 firmware with unlocktool
4: I install CWM with the *.batfiles included
5: I follow the link to flash and root instructed here: http://forum.xda-developers.com/showthread.php?t=2181640
Is this the correct way to do it?

Yeah.Put it in firmwares folder of flashtool for easier locating of the .ftf, then start Flashtool, select the lightning icon on the left, Flashmode should be selected, press OK, find the fw from the left side(assuming you've already put it in the firmwares folder where flashtool is located), and press OK on the bottom there.Wait up, wait for flashtool to say to connect phone in flashmode(Make SURE you have drivers installed first), and wait for it to finish up.It might get stuck on some %, like 84,94, etc don't worry. it will continue.

Will it be enough to install the driverpack in the folder "Drivers" even though the phone does not appear in devices?

Sv: [Q] Roll back to 4.0.4?
Hang on a minute... can I really install CWM on firmware .75 on a locked bootloader?

yep, just make sure you use this version:
http://forum.xda-developers.com/showthread.php?t=2003069
the 6.1 for J.root your phone with unlockroot first, reboot it, and then apply this .bat.make sure usb debugging and unknown sources in security are ticked, too.
there are graphics issues, but it works.

Well... something is not right... see screenshot.
It starts but the it states that there´s an error. Any ideas?

Translation?
also if you have skype, post your ID and we can solve this faster.
make sure you're connecting the phone WHEN IT SAYS TO, not before that.

Hmmm translation?
"Error in processHeader 22. The unit doesnt recognize the command. Error flashing, aborted"
Sorry... not using Skype
Any clues in screenshot? I´m downgrading to .75 FW

try doing what i said, make sure you turn off the phone, remove battery, put battery back after 5 seconds, prepare the files for flashing, and plug the phone in flashmode WHEN THE PROGRAM instructs you to.I've found this to be a problem with the tipo too.Although it was fixable by replacing a loader.sin, but im not sure if there's a loader.sin for the J, i wouldnt experiment also with putting one from the tipo.Try what i suggested, plug the phone when flashtool instructs you too.volume down, remember

Works nice... rooted and CWM installed and working.
I do have one question... On the Xperia J, if I want to modify and so on... witch is best? 4.0.4 or 4.1.2?
Flashed rooted 4.1.2 with CWM and it worked... took out battery and started Flashtool. Started phone with vol- and it started to flash. But it´s stuck at 3%...
Ideas?

I'm out of ideas as I don't own the J, and that root procedure is quite difficult to understand.

[Q] Need help with C2104 and C2105 - How to upgrade? [SONY XPERIA L]

Hello there,
This is my first post on this forum, and I'm kinda new.
I've rooted many of my previous devices including XPERIA U, X10 Mini Pro, Samsung Galaxy S Duos, Galaxy Grand Duos etc. and I've never had any problem. But XPERIA L has been creating troubles for me, so I had to signup in the forum and ask few questions.
What is the difference b/w C2104 and C2105?
I understand C2105 is newer, and better... but how do I update to this firmware?? Can I upgrade via PC Companion or do I have to use FlashTool? Can someone give me a link to a tutorial that could help me or written text step by step?
I'm unable to root my XPERIA L on C2104. I've tried each and every method, none of them works. I even tried Framaroot, NO LUCK. How do I root it? Do I have to upgrade to C2105 firmware version in order to upgrade?
Any help would be kind
I'm new so I'd love to clear my doubts - sorry for troubling ya'll.

With motochopper

About MotoChopper, I'll try in a few minutes and tell you.
Sorry to bother you with all those silly questions.

Waiting for device..
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
I have enabled USB debugging mode also, wonder why this is happening! I really wanna root my device. What do I do guys?

C2104 and C2105 ftf are both same, just basebands are different. If you flash a C2105 ftf without excluding basebands then you will permanently brick your radios and hence lose network. For rooting install proper drivers like adb, Sony Companion does that and if you fail use Flash tool for drivers, also if you are using Windows 8 then use Google to find out how to install drivers.

Hey shivam,
Thank you for replying and I extremely apologize for bumping in the thread after a long time, I actually was very busy b/w these days. What I simply want is to root my XPERIA device. It seems that Flashtool will help me out.. and yeah, about drivers, they're installed in my computer already; I'm using a Windows 7 PC.
Can anyone kindly provide me the link to download the latest version of Flashtool? The official website is down, I guess - it's not opening for me.
I'll try root my C2104 with Flashtool and respond you guys.
Thank you for your quick responses, you all surely rock.
Expect my reply again soon

I have updated my phone to the latest version, and I haven't unlocked my bootloader.
Can I still root my XPERIA L using DooMLoRD's rooting kit v17?

Motochopper for version 2.17 Far as I know it only work motochopper.

@OP
just yesterday I was in the same boat as you are .
I'm successfully running vengeance + Clean n Tweaked now.
Anyway, I'll try to tell you a few things that I did not know and helped me a lot.
* Install Fastboot and ADB from http://forum.xda-developers.com/showthread.php?p=42407269
[I did not use that cuz I have the whole Android SDK]
* Remember these keys:
-- While plugging in phone to the PC =
Vol up = FastBoot Mode
Vol down = Flash Mode
-- After you have CWM installed
When you start the phone and Sony logo starts showing keep pressing volume down and you will get into CWM Recovery
* Use http://forum.xda-developers.com/showthread.php?t=2307983 to root.
It definitely works. Keep doing the partial root part until SuperSU loads the binary successfully. Remove SuperSU and restart between each try.
* Get Flash Tool from http://www.flashtool.net/ and not the Official Sony Flash Tool
* If you have C2104 use C2104 stuff ONLY and NOTHING ELSE.
* The firmware update is very huge so I downloaded it from https://docs.google.com/file/d/0B16rNZZxP33EdXhfNml1ZjBFNXc/edit and used the Flashtool to flash it
What else do you want to know? I'll help as much as I can.

Well what I want to know is whether I can root it with DoomLord's rooting kit v17 or not.
Here's a summary of my device:-
I have C2104 with the latest software / system updated via PC Companion.
I tried rooting using Motochopper, which failed.
I tried framaroot, which failed again.
I really need to root my device.
Thanks ya'll for replying..

I'm sorry but I don't remember if I tried DoomLord's. Even if I did I don't think It worked for me.
I didn't try framaroot cuz according to the thread it's for the older firmware. Might work for the newer one too but I didn't risk it.
Since you have the firmware now just keep trying MotoChopper via the thread I have given you the link to. It will work.
Also, post a log/screenshot of what you get when you run it in your PC.

Sure buddy,
Will give you in few 1-4 hours.
Thank you for your assistance.

No luck yet again..
I Installed after following the rooting steps using XPERIA_L_ROOT, and then installed SuperSU, which says "There is no SU binary installed, and SuperSU cannot install it. This is a problem!".
I guess that says to "UNLOCK BOOTLOADER".
Any possible way to root WITHOUT actually unlocking bootloader?

Soft bricked Tipo

Hi there,
1. I am fed up of my Tipo's lagging touch (responding after half an hour, miscaliberation). I update the firmware using Sony companion and tried to install one of the Jelly Bean roms on the stock ICS using CMW. It some how soft bricked my phone. Can any one tell the reason?
2. With lot of effort I installed the stock ST21a 11.0.A.4.22 Sony Generic kernel (using Flashtool). It is same laggy and miscaliberating. Did I not reformat, similar to PC? shouldn't it be fresh and new ?
3. I am not trying to install JB rom. What is the correct way to install? Should I worry about any seperate parts like Kernel?
4. To install JB rom (Paranoid Android) I tried to root the device, but the flash tool says "no root exploit for this version". If i cant root. I cant install CMW. I cant install frest rom. Is there any other way to install ROM?
I am stuck in the above points after my research, and will appreciate your help.
Thanks in advance

Yeah, but those two have the same effect. Repairing with PC Companion is exactly the same as flashing a .ftf. And if that didn't work, PC Companion won't.

ADB / Fastboot / Driver problem

Hey guys,
I am pretty new to the rooting stuff on the Nexus.
I read the sticky threat from rootSU (http://forum.xda-developers.com/goo...urce-guides-info-threads-linked-read-t2784527) and followed his description. So I installed ADB and fastboot through the "15 sec. installer" (http://forum.xda-developers.com/showthread.php?t=2588979).
So fast so good, everything went fine. But as I tried to "check" if ADB and fastboot are recognizing my device with the command "adb devices" and "fastboot devices" in cmd, I got some strange output (look at the picture).
How can it be that ADB "sees" my device and fastboot not? What I did wrong there?
(I didn't installed the drivers with the 15 sec tool; when I plugged in my device to the computer, it downloaded the drivers itself)
Any help would be very appreciated!

Follow the next step on my thread and install the naked drivers

Okay thank you!
I'll try it tonight and report back.
I also thought of a problem with the drivers, but I thought that I messed up with installing ADB and fastboot somehow, because ADB could recognize my device.
One question again: When I uninstall the Nexus 5 drivers and I reconnect my phone to the pc, it download the driver itself.. How can I stop that to install the naked drivers?

Damn, thats it! I am so dumb! I don't know how I could forget that.. I read it some hours ago.
After I went into bootloader mode, fastboot recognized my device!
Thanks a lot guys, now I can go to the next step to root my device! =)
Btw.. another question, which is offtopic - does it makes a difference to root KitKat or Lollipop? I guess the guides around here are all made for KitKat and I don't want to mess up. :/ Thx!

@rootSU has posted some new guides on rooting Lollipop, so best read his threads in the General section

To root Lollipop you have to use Chainfire Auto Root. There is extra security in Lollipop that keeps the old root method from KitKat from working.

Oh I see..thats annoying. But thank you for your answers! I guess I'll read those threads. =)
Btw.. Can you guys tell me if I understood everything..:
To go back to the official 4.4.4., I don't have to root my device, right? I "only" have to unlock my bootloader and flash the official factory image through fastboot. And afterwards I could root my device using the guides around here on xda.

Oh, actually thats all I wanted! =)
On my old Samsung Galaxy Ace you had to root your device first, before you even could install another stock rom, thats why I thought it would be the same for the Nexus 5.
Thanks alot, I'll save my data on my PC now and start with the "downgrading"!

Yeah I think I got it now. I unlocked my bootloader and flashed the official 4.4.4. factory image from the google developers website. Afterwards I booted into the stock recovery and wiped data/factory reset and reboot. Everything is fine now!
Thank you for your help! Learned a lot of basic understandings.

To root Lollipop you have to use Chainfire Auto Root. There is extra security in Lollipop that keeps the old root method from KitKat from working.

There are multiple methods. Cf auto root is just one of them.
I documented all methods in general. There's a link to my thread from "sticky roll-up in general

I usualy root my Nexus by booting into a custom recovery (TWRP), flash the latest superSU.zip and any mod i want and reboot/done That way i keep my stock recovery.

[Q&A][Root]Rooting with Locked Bootloader - NO OTA Method

After much tampering I managed to identify a procedure to root our phone(s) leaving the Stock ROM intact (addition of rooting apart, sure). This will remove the requirement to do an OTA update, which in the future could remove the rooting if any update will be available (Lollipop maybe?).
The process is very straightforward and has been tested in both OS X and Windows. Here it follows:
THIS SHOULD WORK FOR ALL XPERIA PHONES WITH KITKAT INSTALLED WHICH HAD A PREVIOUS ROM VULNERABLE TO TOWELROOT.
If your phone started with KitKat 4.4.4 or later and you want to keep the locked bootloader you may be doomed.​
GENERAL GUIDELINES:
Be sure to have the full FTF for the stock ROM you are currently running
Flash only the kernel of a ROM for your phone vulnerable to the Towelroot exploit unchecking the wipe checkboxes
Reboot the phone:
The phone will bootloop, but it doesn't matter. The Linux kernel and adb are alive and thus the "Towelroot" vulnerability is exploitable by rootkitXperia
Run rootkitXperia. After the rooting it should get stuck when trying to reboot the phone(*). Interrupt it with CTRL-C
Flash back the kernel for the ROM in your phone
Reboot the phone
Manually run the command to have the RIC permanently disabled:
Code:
adb shell "su -c /data/local/tmp/install_tool.sh"
(*) In some phones (Xperia Z?) rootkitXperia may not get stuck. If the phone reboots the rooting should be complete. Just flash back your original kernel and it should be done (untested).
The following section will explain in great detail every single step needed. It also includes all the links to the SW and procedures needed:
COMPREHENSIVE TUTORIAL:
PREPARATION:
Have your phone updated to the last ROM
Download Flashtool: link
Download rootkitXperia: link
Have adb installed: Suggested links: OSX/Linux - Windows
- Windows only: Install the phone drivers (probably using Sony PC Companion. I dunno, I don't use that Windows junk )
Enable the USB debugging: HowTo
In Settings/Security enable "Unknown sources"
Make it sure Flashtool/adb can connect to the phone: just try "adb shell" from the terminal.
Download a Jelly Bean stock ROM for YOUR phone: link for D2303
Otherwise for D2303 (but it is confirmed working with the M2 Aqua D2403 as well) you can use the attached FTF (kernel only)
From Flashtool download the FTF of your latest ROM (Menu "Devices/Check Updates" at least in OS X). Be sure to use the same ID
You may want to make a full backup using the Sony system app "Backup and restore" (or equivalent in other languages)
ROOTING:
Launch Flashtool in your Mac/PC
Power off the phone
While holding the Volume Down key connect the phone to the Mac/PC via USB
The phone top led should blink red and then green
Flashtool should report that the phone is connected in flash mode
Select the JB FTF of your choice (full RoM/kernel only).
In OSX Flashtool is glitched. You may need to select an FTF and then move upward with the arrow keys
Exclude all but the kernel. Uncheck the wipe checkboxes
Proceed with the kernel flashing . The blu icon with a thunder
After the flashing has terminated disconnect the phone from the USB
Start the phone:
This is the tricky part. Android now will bootloop. But we don't care, because the underlying Linux is well alive!! adb works and so it does the Linux kernel/OS.
And that is all we need, because rootkitXperia exploits the Towelroot vulnerability but without the need of launching the graphical interface. Just hurry a bit because it may or may not last forever.
Connect the phone via USB
From the terminal cd into the rootkitXperia directory
Launch the script: install.sh in OSX/Linux - install.bat in Windows
When the script gets stuck at the phone reboot terminate it (CTRL-C)
At this point, with the phone still in bootloop, you may check if the rooting has been successful. Just type the command:
Code:
adb shell "su -c id"
which should report
Code:
uid=0(root) gid=0(root) context=u:r:init:s0
If it doesn't something went wrong (it shouldn't).
DISABLE THE RIC (enable /system read/write):
Disconnect the phone
Power it off
Hold the Volume Down key and connect it to the computer
In Flashtool flash the kernel of your latest ROM.
Like before exclude all but the kernel, no wipe needed
Also there is an issue with 18.3.1.C.1.15 installed via PC Companion/Sony Bridge for Mac. One should flash (thus not excluding it) the "BOOTBUNDLE" as well as shown in this post
Disconnect the phone from the USB and reboot it
Connect the phone
Manually run the command:
Code:
adb shell "su -c /data/local/tmp/install_tool.sh"
Reboot and enjoy your rooted phone!
What to do next:
Press "Thanks!"
Backup your TA partition: link for OS X
Put a copy in your most favorite Cloud service (Dropbox/iCloud/Google Drive/Whatever). It's better be safe than sorry.
Update SuperSU binary and apk
Install adaway to get a rid of those annoying commercial
Anything else you rooted your phone for!
Unrooting/Recovery
You may need to use the OFF button near the SIM card slot if anything went wrong (like if you forgot to uncheck the wipe flags). That shuts down the phone. You would need a needle (or something very small) to push it. (**)
Flash with Flashtool the kernel and system from the ROM you previously downloaded to keep your data - or -
Rebuild the ROM with Sony Bridge For Mac/PC Companion
(**) Thanks to Vino Kulafu for the tip.
JB Kernel from the Xperia M2 D2303 FTF attached:
It's confirmed working with the following devices:

Yap, I have just test it and everthing is working fine. I was using Windows. And i could also update su binary without any problem. Thank you for sharing us this method which reduce a lot of wasted time.

Successfully rooted Generic Philippine D2303 4.4.4 KK firmware, with full R/W access using the above instructions.
However, I suggest that the above steps be updated for clarity. Happy rooting guys; this is a much more convenient way to root, albeit complicated.
This should be moved to General section or Android Development section so people can see this thread easily.
:good:

Do you mean to make a short version? I mean, as it is now it's a full guide, from A to Z. I was thinking about making a section with the 4-5 steps for the skilled users. Too bad I didn't think about reserving the second post. Is there any way to have it added? Otherwise I'll put it in the bottom with a reference on the top.
EDIT: Added a generic procedure on the top.

yeah, I was thinking about making a thread there pointing to this one as well. The process is quite generic, although I think in the Xperia Z rootkitXperia does reboot the phone disabling the RIC.

No need to make a short version, my friend; it's good enough. Here are some suggestions though:
1. I think the portion about holding the up volume key is wrong since it boots the phone into fastboot mode while we need to go to flash mode.
2. Kindly stress the importance of unchecking the wipe checkboxes in flashmode. If not unchecked, you could end up with a bootlooping phone wherein the root kit will not function since the adb debug setting has been reset, which leads to #3.
3. Make use of the OFF button near the sim card slot when faced with the situation described in #2. Just flash back the original kernel and repeat.
My experience was this:
I didn't wait for reboot; I cancelled the procedure when it hung in the reboot part. Then I shut the phone off using the OFF button near the sim card slot, then flashed back stock KK kernel only. Afterwards, I proceeded to the disabling RIC then reboot again. Presto, all is well.
:laugh:

Ok, let me see:
1. Crap. I always get confused. It is Volume down, then, I just checked. I'll fix it.
2. Oh, I didn't think it could get so bad. I just unchecked the boxes to avoid to lose my data.. Well, yes, thinking about that it makes sense now.
3. I'll add it. Thanks.

As i know, with Locked bootloader even if you hold volume up (+ button) it will reject the connection with phone. Otherwise great guide and you should contact someone of moderators to move this in General section.
Thanks

how the Xperia M2 Aqua (D2403) ?
Is there a solution root for D2403 with locked bootloader ?
sorry bad my language

No, no. One just needs to hold Volume Down. WIth the locked bootloader we can flash all FTF we like as long as they are from Sony.
I also made a new thread in the general section just with the "General Guidelines" also pointing to this one. But thanks.
Actually it made the portal!

If it had a Jelly Bean ROM just download the FTF (don't ask me from where) and follow this guide.

sorry .. no I do not understand
after successful with rootkitxperia , so need to flash back stock kernel before?

Yes, you need flash back stock KK kernel. After doing that, the phone should boot properly. Then you can proceed to disabling the RIC module steps.

Why is this?
anyone can help ?

sorry

You're welcome!
So, let me understand: did you flash my attached JB kernel for the M2 D2303 in the M2 Aqua D2403? I'd like this to be confirmed so in the case I will add it to the guide.

The kernel I attached in the main post works for the D2403 as well. I updated the guide confirming it. Download it and follow the instruction step by step.

After flashing latest kernel , phone just shows sony then blank screen...but adb can detect the device...
any fix??
