flashing a FTF will remove the custom recovery and root but not lock the bootloader, but you can lock it with flashtool or by restoring the TA bckup

Thanks alot
So that means I don't need to unlock the phone to flash FTF?

[Q] Xperia neo cant root or unroot

hi,
i have xperia neo and i rooted it before using DooMLoRD_v3_ROOT-zergRush-busybox-su
i updated software using pc companion to 4.0.2.A.62 i lost root but superuser was still installed
i tried to unroot it and root again but no luck superuser.apk is read only and all rooting methods don't work for me
please help i tried everything even factory reset but the superuser is still there and i can't remove it to root again
P.S: is there any way without needing to flash rom ?
Build .62 is currently unrootable so when you updated the firmware it probably broke it. I think the only way to fix it is to flash the rom.
Sent from my MT15i using xda premium
yea you are right..
you must downgrade to .42 for root option..
Thanks guys for the reply.
the problem was solved after i downgraded to .42 and then used FlashTool to root the device if someone had the same problem and wanted to solve it
unfortunately the firmware i downloaded from the form is international version and doesn't have the Arabic language user interface, i will just have to live with it
.62 is rootable, using recovery. You need to flash RootXperia.zip with recovery for locked bootloaders.
Cheers.

Ita not required root man, just usb debugging on and unknown sources on.

I've tried that and it doesn't work.
When you try to install CWM it says that you need allow root access on the screen, but nothing will happen since you don't have root yet.
I had to downgrade.

Have you tried it? It does ask for root

Installing incorrect ROM version caused this problem, for example installing Mini Pro(SK17) when you actually have Mini(ST15).

Get back to the original ROM using SEUS or flashtool. I think that could help.

Install stock firmware, lock bootloader and try SUS. Which way did you unlock?

If you unlocked the official way, then use the Relock_bootloader.ftf file and flash it via Flashtool.
If you didn't use S1Tool, then don't use it now either.

its not important if your device is rooted or not. (relocking)
but you should know that you have to use a stock kernel when your bootloader is locked!

re-locking doesn't wipe anything!
just unlocking will erase data partition.
Ok thanks, im on stock ics using advanced kernel (ics11.elf) for using cwm—recovery, so now how do i gain ics stock kernel after i relock?will relock automatically put me back to stock kernel or will i have to flash stock kernel separately before/after relock?

you can:
1) flash stock kernel with flash tool( select your ftf 4.0.4 rom & use exclude option)
2) re-lock bootloader
its not important when u flash the kernel! but the device with custom kernel & lock bootloader cant boot.
So by using flash tool on stock ics rom ftf will surely give me the options to only flash (kernel) without flashing the hole ftf rom by selecting (exclude)??

[Q] Rooting, Unlocked Bootloader, Custom Recovery

So I I finally rooted, backed up my TA partition, unlocked the bootloader, and flashed CWM/TWRP. Took me forever to do on windows 8, but finally figured it out.
My question is, what effect does flashing OTA updates and/or ftf's have? Will I just lose root? Or will I lose custom recovery as well? Just want to make sure since i'm sure the B.2.257 ftf will be posted shortly and I will want to flash it!
Similarly, if I were to change the CDA to get B.2.257 OTA, would I just lose root? or would I lose recovery as well?
I don't know about ota but flashing a ftf makes you recovery and root go bye bye.

Thanks for the reply. Bootloader remains unlocked correct? So just re-root and reflash?

Yes. Only way to relock is by restoring your probably backed up TA partition.

Afaik seus might brick your phone as your bootloader is unlocked.. Best is to use flashtool and flash .587 firmware and sell it bck..

If you're using flashtool, then there's no need to lock the bootloader.

yes you can relock the boot loader, but you don't have to, you can reinstall the stock os without relocking the boot, no you don't have to relock to use stock os
