[Q] What happens when I upgrade to lollipop - rooted, locked phone - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hi, would like to know if it is possible to upgrade to lollipop using pc companion. I am currently rooted, locked bootloader, custom recovery. Build no. 14.4.A.0.157. If so, will I have a stock official rom with no root and stock recovery? Thanks. I would like to return back my phone to stock with latest updates.

There will be no root. I'm not sure what about the custom recovery though. Also I think SuperSU or Superuser won't be deleted.

in general there will be NoRoot.
And if you want to update to an official android version I suggest to download the ftf of it and flash with flash tool that would be easier

Something easy is flash your new firmware and use a kernel like "Advanced Stock ICS Kernel" to root and finally reflash your stock kernel if your want its improvements, you can unlock your bootloader anytime, and the best custom room is Cyanogen, it just needs to flash an file in recovery mode.

root/twrp to official JB update

Hi
My brother have sg3 from rogers,.. i did root on it and installed twrp ,.. we were thinking about flashing custom JB ROM, but official came out yesterday.
can we safely do OTA update, or we have to un-root it and get rid of twrp (even though i dont know how yet) )
Thanks
Not sure if you need to be unrooted, but you definitely need to be on stock rom and stock recovery.
ROM is stock, but have twrp ,... hmmm
how can i get back to stock recovery?
There is an odin package that has just the stock recovery over in dev section

Root + Original Bootloader

To root the phone I had to install CWM as the bootloader and then run a zip file to obtain root.
Because I installed a custom bootloader, I can't receive OTA updates anymore so I can't get the S3 Premium Suite update.
How can I revert to the original bootloader and maintain my root? Can I just flash the original bootloader with Odin?
Any advice would be appreciated.

No you installed a custom recovery not a boot loader.
Because you installed a custom ROM you can't get updates
To get the original RECOVERY you need to flash a stock ROM thru Odin, and to update anything stock you need to remove root to get any Kies updates or else youll get errors.
And even so I don't think the ATT S3 has had the update to Premium Suite.
(Anyone can correct me on this one)
I think only international S3 has been updated to Premium suite

you are correct on all this, jayRokk.
OP, there is an unroot video guide near the bottom of post #2 in the link in my thread. the stock, unrooted firmware can be located in the android development section.

[Q] bootloader question

Im on stock image 4.3 with root. I just installed TWRP 2.8.6.0 version for 4.3 . As I was looking at the rom's the majority of them want me to be on bootloader 4.2 or 4.4 before I can use the rom. What is the safest and easiest way to get there? the last time I modded a phone was with my HD2.
sorry for the noob question. I have been out of the loop for a while.
Thanks

If I goto sammobile to download N900TUVUENK3 and flash it with odin would that give me the boat loader I need? also would I need to upgrade twrp at that point? is there a document that covers this? any help would be appreciated.
Yes just be total stock 4.3 then flash the N900TUVUENK3 rom using odin and you will be able to flash any 4.2, 4.4, or 5.0 rom available. You just have to be 100% stock to do it including recovery. After you install the new rom then you can root it and install any custom recovery you want. Thats what I did. Revert to total stock, flashed the NK3 rom, rooted, then installed recovery. After that you will have a 4.2. bootloader and will be to install any rom out there. Hope this helps you out.

New here

Hi guys
I m new here, i dont know much about this stuff.
So i have lg g3 d851 t mobile version which is previously unlocked (i dont know which tool was used). The problem is the phone lack some base app like radio and update center ect and its unstable, so i want to flash it.
Phone statue:
+ android version 4.4.2
+ rooted
+unlocked
+bloatloader i think locked
+stock recovery
My question is
Can i install costom rom without losing the unlock? If no can i install stock rom like 5.1 or even 6.0? do i need install 5.1 before 6.0 ?
Pls help
The bootloader isn't unlockable per se. You obtain a custom recovery by downgrading to an earlier android version with vulnerabilities you can exploit to obtain root access. Then you use the root access to flash a custom recovery. You can do whatever you want (whether it be flashing a custom ROM or a stock ROM through lgup), you can always re-root. You'll never lose the unlock since technically it doesn't exist.
With that said, since the phone already has root, you can flash twrp recovery using terminal or adb and flashing any ROM from there. You can also flash the latest stock ROM on a PC using LGUP or lg flashtool or in recovery using the stock ROM by mesa.
Read through the guides here and decide what exactly you want to do based on your preferences. You can always re root if you lose it in the process.
As a side note, there's no radio app for this model as there's no FM transmitter in this device.
Hope this helps.
