flashtool 4.0.2.A.0.62 root

Can the new flashtools root 4.0.2.A.0.62 for arcs with locked bootloaders? Already upgraded once to find out i couldn't root it. Has anyone done this successfully with a locked bootloader as I don;t fancy experimenting again.

yes mate flash the old kernel from the .58 or .42 or .283 FW by excluding baseband & system in flashtool b4 flashing after that root as normal with zergRush..

Thats what i did last time i experimented and it didnt work. i installed 62 then flashed the 42 kernel with flashtool. But zerg wouldnt root it. But i flashed the kernel only. in one of the 62 threads there were links to getting it rooted with locked bootloaders. This went to a guide with nothing about locked bootloaders in it, only unlocked.

somewhere here in the forums is a thread about CWM for locked bootloaders, with that you CANNOT flash custom kernels, but old kernels in zip format, hang on i'll get you the zip + the link for the locked BL CWM.

http://forum.xda-developers.com/showthread.php?t=1390771 this is the link for CWM: follow these instructions for the arc : 1.Run install-cwm?.cmd
install-cwm1.cmd for Xperia Arc / Neo / PLAY
2.Enable USB Debugging on device
3.Connect your device using usb data cable
4.Follow on screen instruction
and here's the kernel it's the .283 kernel

it wasn't custom, it was the stock kernel from .42 flashed to .62 and zerg refused to root it. Although apparently this worked on previous versions as i tried flashing the .42 kernel over onto .62 as a tip from one of the other members on here. but I couldn't get it rooted in the end and gave up and went back to .58.

flash that kernel via CWM

so if done with cwm mod it should work then? Whats the difference flashing the kernel with cwm as opposed to flashtool? Would have thought it be the same.

dont know the difference, but this one worked for me

cheers ill give it a go.

no problem feel free to contact me via PM if you still have problems

I have the exact same problem as you. Did you manage to accomplish anything? If yes would it be easy for you to explain to me the exact steps? If not is it possible to give me the address or send me the .58 firmware for arcs (the ftf file). I wasn't able to find it somewhere. Thanks!

upgraded to .62 then tried to install cwm but it wouldn't let me as the phone needs root permission to be able to install it. So how did you deal with this? I also flashed the .283 kernel with flash tools after updating to .62 and zerg again failed to root the device.

Ok, I'll give it a try.

Before I go back to .58, is there any rumour if Flashtool is going to support rooting on .62 firmware soon?

Nope... the zergRush exploit has been patched on .62 fw and there wont be another exploit on Gingerbread, since we're going to ICS.

is there anyway to root 62 without unlocking our bootloaders or is it nay to impossible?

So far I wasn't able to find a way, so I think I'll just go back to .58 or .42 and root, waiting for the official ICS.

The first file is the unmodified version and can be flashed with flashtool (there's no root).
The other is the exact same process as in Nut's thread, (files were created with his tutorial). Earlier you needed to flashback to 4.2.2 because there was no root on 4.3 and therefore no DualRecovery. If you have recovery, then just flash the zip, poweroff and flash the stripped ftf. Same process...nothing is different.

The official version simply flashes your phone back to stock by removing root and recovery. If I ever sale the phone, ill use that file to restore everything back to factory.
Steps for flashable version:
1 - Since you are already rooted and I assume you have recovery, upload the flashable zip on your SDCard
2 - Flash the ZIP using recovery and power off WITHOUT rebooting
3 - Flash the stripped FTF using FlashTool
Boot your phone and you're done

What if my phone is not rooted, bootloader is locked and is on .569 (4.3) version?? Thanks.

My bootloader is locked too and is unlockable (at the moment), bootloader isn't important. If you want root on your 569, you have no choice, you need to flash back a stock FTF 4.1.2 or 4.2.2. whichever version works with DoomLord's 1 click root method. Once that is done, you install recovery and flash the zip via recovery, power off phone, flash stripped FTF via Flashtool and you're back on rooted 569.

Flashback to 4.1 o 4.2?? Tried flashing the .423 kernels only buy my phone get's stuck on the boot "sony" screen. Any tips?

Which firmware did you flash back to? 10.3.1.A.0.244
1 - Flash 244 FW
2 - Flash Kernel from 423 and reboot phone
3 - Root using "DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit"
4 - Flash back Kernel from 244
and then go on with installing recovery to perform next steps to go back on rooted 569
It has to work, I did a million times!
If your stuck on a bootloop right now, just flash back the whole 244 FTF. it will put you back on full stock.

.244 or .267 FW. I ask because I read on another thread that I had to flash the COMPLETE .267 fw. Is this accurate?? The .267 I have, where can I get the .244?
Additionally, what did you use to back up your app data on the .569 fw? Thanks again.

You can do it with the 67 as well. Process is the same so either 244 or 67.
I always use Titanium Backup to make a backup of all my apps/games, I have the paid version coz I have about 100 apps and don't feel like restoring them 1 at a time afterwards.
I just got an OTA notification about the new 10.4.1.B.0.101 on my phone. Ill probably be creating the files for this one tonight, so maybe you should wait another day before flashing the 569 .... 101 is newer. :victory:

I'm not rooted so TBU is a no go for me. What other back up method would you suggest?
The main reason for rooting now is because I also received the 101 update notification. Better to root now before stuff really gets complicated... again, thanks for the help.

Looking forward to your new. 101 fw (flashable zip and stripped ftf). Got the Ota too for 35mb but won't install, guess because I am rooted(Lb)

[SS/DS]Upgrade/Restore/UnlockBL/Root(Tested on Dual)

Hello guys, I just want to share the steps on how my Xperia M[dual] is rooted and has its bootloader unlocked for about 2weeks dating to this post. I updated my XM to 4.3 and missed the benefits of a rooted android so I found a way to root it(During that time rooting on locked BL was still impossible).But upon searching methods and asking people on how to. I discovered a way on how to root my phone and unlock my bootloader and learned something that will make you feel confident on tinkering with your device.
So basically, Im not pertaining on rooting on this thread but upon reading the steps you might learn something that I also learned
This is for those Xperia M users who upgraded to 4.3 who wants to:
Downgrade to 4.1/4.2 and UnlockBootloader
Root their XM[Unlocked Bootloader][Dual]
Create Firmwares from their own country.
Also to create backups
First. let's assume you are in 4.3(locked bootloader)and doesnt know anything about FTF's and backups and willing to do anything just to install apps that requires root permissions. Just like me
Here are the steps.
1.Make your own 4.3 FTF file from SUS. The FTF from here is for your own country
Here's the guide on how to: http://forum.xda-developers.com/xperia-u/general/guide-how-make-ftf-stock-firmware-sus-t2075736​
2.Flash a FTF file with lower android version. You can search the appropriate FTF file for your device in Xperia M android development.
Here's the guide on how to:http://forum.xda-developers.com/showthread.php?t=2697277​Step 3 will be focusing on unlocking your bootloader. You can read it (if you want to root) or just skip it (if you're only concerned on backups) and proceed to other steps
3.Root your phone while running in 4.2.2 android version and unlock your bootloader.
Search the forum on how to root 4.2.2/4.1 you need to be rooted to unlock your bootloader. Here's the guide for unlocking BL:http://forum.xda-developers.com/showthread.php?t=2484622​Note: Don't install any kernel for now just stick to stock kernel to avoid issues because we will be upgrading back to 4.3. If you read step 1 you definitely have your own FTF backup :highfive:​
4.Flash the FTF file from step 1 and now youre back to 4.3 with UNLOCKED BOOTLOADER, TA-BACKUP, 4.2.2 &4.3 FIRMWARE :highfive:
5.Optional StepThis method is strictly for XM Dual users only, because the kernel in the link provided here is the stock kernel xm dual 4.3 with CWM integration. For XM single users just search you own stock kernel with CWM if you want CWM
Follow the last 2 steps provided here:http://forum.xda-developers.com/showpost.php?p=51559161&postcount=30​
By now you have the knowledge on how to fix your own device. Example: If you got bootloop by flashing tweaks or kernels you can just flash your own FTF file to have a fresh start again. :victory:
Proof that I did this also. This is a private conversation of me and ansebovi
ansebovi said:
Tommienots said:
So ill summarize all you told me so i can proceed
my current phone version android 4.3
1. Make my own FTF file in this current version.
2. Flash FTF file with android os running 4.2.2
3. Root while in 4.2.2
4. Back up TA partition
5. Unlock Bootloader
6. Flash the ftf file from step 1
7. proceed with the steps in this link http://forum.xda-developers.com/showpost.php?p=51559161&postcount=30
upon completing these steps, am I rooted now running 4.3?
thats what i understood. correct me if im wrong.

[Q] Root firmware .101

Hi guys... i need root mi ZL whit firmware 10.4.1.B.0.101 but not as... i need help
Sorry for my bad bad english :crying:

You have two options
1. unlock your bootloader and flash root(warranty, DRM keys lost)
2. downgrade to 4.2.2 firmware
backup TA partition then flash a 4.3 pre-rooted stock rom
lastly restore TA partition(must be stock kernel)
stock rooted phone with warranty and DRM keys
If you don't care about the warranty, I'll suggest just go with option 1, since option 2 might be time consuming.
Option 2 is always better. Who knows when your phone is going to break.

Not the OP, but am trying to figure out how to do this. All the root threads are a year old, so I want to make sure I have my facts straight before messing anything up. I have a C6506, US Generic but I don't want to lose my DRM keys or Warranty for resale reasons, so am trying to do this the "locked bootloader" way.
1) Downgrade to 4.2.2 firmware. Do I do this with Flashtool? This doesn't require unlocking the bootloader?
2) Root it .. Doomlord method? The Flashtool website says it can "root", too, but it offers no details on which method. What's the best way to go?
3) Install custom recovery. Which one? I see Nut's thread all talk about a dual recovery, but is that necessary? Can I install just one?
4) Is there a pre-rooted 101 for the C6506 US Generic? I can't seem to find one...

deleted (doesn't work with .101)

CokeJunkee said:
If you're on .67 or .101 firmware, just flash the .423 kernel via Flashtool.
Because it is a Sony stock kernel, you do not need to unlock the bootloader for this step.
When flashing is done, close Flashtool and reboot your phone.
Enable 'unknown sources' (found in security settings) and 'usb debugging' (found in developer options).
Now use Doomlord's method to root.
When rooting is done, it's time to install a recovery to your device.
If your're going to use a custom rom based on Sonys stock fw (like ExistenZ and RomAur), I strongly recommend using [NUT]'s dualrecovery.
AOSP roms (CyanogenMod, P.A.C., Omni, etc.) bring their own cwm recovery.
After root and recovery, turn off the phone and flash either .67 or .101 kernel, corresponding to your firmware.
Now it's time to backup the TA partition.

This is extremely helpful - thank you for providing links. I am wondering why this is so different from the method laid out here:
http://forum.xda-developers.com/showpost.php?p=51612704&postcount=12&nocache=1
Seems like your version is much easier, so I wonder why someone would go through all that trouble for the same result...
Also, won't I lose root once I flash the .101 kernel? Do I get it back using recovery?
Also also: the kernels linked above are for C6503 and C6502. Can I use the full FTF files for C6506 and just deselect flashing everything expect Kernel? It looks to be the same files, except that rpm.sin is included in the full files and not in the kernel FTFs.

when i flash a .423 kernel i got bootloops, am i doing something wrong?
after flashing back the .101 it boots normal

[Q] Rooting z1 compact stock lollipop

We all have gotten a sneak peek of Sony's lollipop update onto our beloved z1 compact. Through the many ways available I for instance used an ftf file. But they do not come pre-rooted like the zip file alternatives.
The only way to root ftf I am told is to flash a kernel pre-installed with a recovery then flash SuperSU zip. I have flashed like 3 different boot.imgs only to find no TWRP/Philz/cmw recovery.
Can anyone give me a WORKING kernel that will boot into a recovery? Would really appreciate this.
Found my solution
Edit: I just found a cm11 snapshot boot.img kernel, flashed it. Booted to recovery and flashed a pre-rooted rom zip. Easy as pie.
Thanks all.

Just flash KK firmware 108, root it, install recovery latest version, and afterwards flash any customised prerooted ROM of your choice.

This is too much work. Work that I have to do. It's the only way to root this ftf. damn it

It's up to you.

I made a pre-rooted ftf using PRF creator and compiling the SUPERSU v2.37 and Z1C locked dual recovery 2.8.12 from Nuts site.
You can use Xperifirm to download the the firmware, then use Flashtool to decrypt the fileset and create the FTF, then you're good to go.

I'm from the UK but I used the "Customized US" version. It works all the same, I've put together a UK one now but I'll need to wipe data before I can use it.
I'd share if I didn't have awful internet. The file is massive, unfortunately.
You'll find multiple threads on how to do different parts.
You need to create your pre-rooted firmware, then you'll need to download KK with Xperifirm (probably .108) and flash it with Flashtool.
Root KK using Easy Root Tool and install XZDualRecovery using the desktop client.
Once you're rooted with SuperSU/SuperUser and Recovery you can install the pre-rooted firmware (PRF) as a flashable zip within Recovery itself.
There's also work arounds for Xposed which you can find too, I've used them and it's all working as it should for now.
I also have a locked bootloader, so don't worry about unlocking it. I'll have a look around for the threads I used and post any I find.

I'll leave you to find your own SuperSU or SuperUser zip, same with XZDualRecovery as they're frequently updated so you're better off finding the latest versions.

But how can you flash 108 if you are already on 242 and you have a locked bootloader? You must unlock it first...

OK, there seems to be some loss in translation somewhere. Hope this will clear up some stuff:
1. Flash KitKat (kernel, system, everything).
2. Root it.
3. Install recovery (here)
4. Since you don't want to make your own pre-rooted firmware, here. Click on 'Google Drive' for the zip, and FTF. You need both.
5. Put the zip in your SD card/internal.
6. Boot into recovery and clear all data (dalvik, system, data, everything).
7. Flash the zip. DO NOT REBOOT.
8. Shutdown and use Flashtool to flash the .ftf you downloaded. Check System and Baseband on the 'exclude' column.
9. Have fun!

@dazzerfong OK,first of all thanks for your answer. What I'm asking is how did you do the first step with locked bootloader.
Flashtool->Flashmode->KitKat 157 FTF->Then root it blah blah?
Are these steps correct or not? Im about to try today cos I really miss root on my phone.
If you are already on Lollipop and your bootloader is locked you can get root this way.
1.Download the correct KitKat (.157) ROM for your country/operator using Xperifim.
Convert it to FTF using Flashtool. (there are tutorials,search)
2.Flash the FTF you created using Flashtool's Flashmode. Include everything.
3.Root your KitKat (.157) using the forum's tutorials and also install [NUT]'s recovery.
4.Boot into recovery and flash your pre rooted ROM in flashable zip format.
(There are also tutorials on how to create this with Xperifim and PRF programs).
5.Enjoy rooted Lollipop with locked bootloader.

@dazzerfong OK,first of all thanks for your answer. What I'm asking is how did you do the first step with locked bootloader.
Flashtool->Flashmode->KitKat 157 FTF->Then root it blah blah?

Yep! All done with locked bootloader (or, if you want, unlocked, but you're wasting your time if you're unlocked). So, first you flash the FTF of a KitKat ROM.
Rooting, use Towelroot or something. No idea why, but Towelroot refuses to play with my TWRP (recovery), so I used the old method.

@dazzerfong
One last question cos I just did all the steps but I couldnt reboot into Lollipop after flashing my pre rooted rom zip file.
6. Boot into recovery and clear all data (dalvik, system, data, everything).
7. Flash the zip. DO NOT REBOOT.
8. Shutdown and use Flashtool to flash the .ftf you downloaded.
Check System and Baseband on the 'exclude' column.

On step 8 which FTF you mean exactly? I assume you mean the FTF from which you created
your pre rooted zip initially? In my case the Customized GR version?
N.

You should have downloaded 2 things so far: the zip, and the FTF. That FTF is Lollipop stock: doesn't matter where it's from. Flash that in Flashtool, but remember to check 'System' and 'Baseband' in the 'Exclude' column.

How did you downgrade really?
You just flashed the 157 FTF in flashmode? It's doable?

Downgrade to .108 (with flashtool) in order to directly root the phone, whereas with .157, you'll have to flash an older kernel with flashtool in order to get root.
Once rooted, just get yourself a flashable prerooted firmware (zip file) and flash it from the recovery (after a wipe factory reset; wipe data; wipe cache; wipe Davilk Cache and Wipe System).
