Currently i'm on trinity rom. And now i want to unlock it without flash the stock ftf. Is it safe ?

It is wise to use stock ROM but i believe it is possible to unlock it while on custom one. Just remember to backup TA partition

Unlocking your boot loader wipes all user data on the internal memory. Back this up too.

Hey Guys,

Till date, I am unable to get root.
I'm looking at using my Carrier's stock firmware.
Build: 9.1.A.0.490
Carrier: M1, Singapore

Downgrade to ics, Root, then follow the instruction s to upgrade whilst keeping root

Yes it is, just flash an ICS ftf

EDIT,
Sorry my mistake, now I am at my PC I can see you have a V.
In which case rooting is easy..just unlock you rbootloader and flash an insecure kernel.

I think that app should be patched directly on device you want to install it. Or maybe you had installed "normal application" on xsp first, didn't work, patched and tried to update? I had a problem with gta:sa where obb files blocked me from installing patched app. Deleted it and it worked just fine.

There are threads in dev section. I think custom fw is worth trying as well. Even better than stock. I didn't want to dabrand my phone when i got it and later go away from stock rom, but now i'm sure cfw are being done to be greater than stock. There you can find detailed instructions

Yes you will lose root and you will neednto re root unless you flash a pre rooted ROM and yes your bootloader will still be unlocked the only thing that can relock the bootloader is restoring the TA partition

When facing with this problems, it is recommenddd to immediately flash stock firmware upon shutdown of device. Use flashtool and flash ur device's stock firmware to your device quickly

Which Williams kernel? Cm ones cannot be used on existenz
Sent with the XDA Premium Application for the XPERIA SP running CM11s
I 100% guarantee it was the stock based kernel. Anyways, as it is still early in the morning here, I am just gonna write down some steps here. 1. Flash CWM for locked bootloader
2. Restore previous backup
3.See if it works?
4. Factory reset if it works
5. See if bootloader unlock allowed changed from yes to no and if yes unlock bootloader
6. Flash existenzultra
