Need help with removing custom rom - Xperia Z Q&A, Help & Troubleshooting

Hey guys,
I have an xperia Z
Model number: c6603
Android version: 4.3
Build number:10.4.1.B.0.109
I let my friend install a custom rom on phone and I do not want it anymore and want my stock firmware back so i can install official updates. I have little to no knowledge on android rooting and flashing roms, i tried searching on the forums but i just couldn't find the answer so i had to make this thread.
I do not have much idea about the rom installed too apart from that its called eXistenZ rom and the OTA updater app says
ROM version 7.0.0
OTA Updater ID: xzexistenzultra
that's pretty much all the info i can think of that i can tell you. If anything else is required let me know, i'll find it and let you know. Please guys, any help will be appreciated.
Thanks in advance.

Nope, trust me. I bricked it a lot of times and Pc companion fixed it. Just click Repair my phone, follow instructions, wait for the long download and it will do a clean install of the latest sony firmware.

Also existenz roms do a lot of stuff while maintaining the Sony aspect. Yet it can be quite unstable. I had my fair share of issues.
So restore your phone, Root it, DO NOT UNLOCK BOOTLOADER (unless you make a backup first), install Xposed framework + desired modules and you'll have most of the tweaks found in curent flagships .

I downloaded a version and I couldn't update from the update service because it says that the rom that is installed is custom... With a little search I found a guide of re branding an X10... Why to re brand a phone?

check me up on this, but the reason your ROM did not undergo its official update is probably because you have your hard SPL still installed? try re-installing your stock SPL and see if the update works. i have attached a thread with a video guide on how to go about it. numbers 4 and 5 should apply to you.
http://forum.xda-developers.com/showthread.php?t=497511
alternately, what you can do to avoid the SE update all together would be to install the R3A/B firmware. that is the firmware that the update provides, from an R2A/R1A. so installing an R3x firmware should be as good as the SE official update. you can get the R3x/R2x/R1x ROMs from this thread. my advice, go for the R3x ROM, so you dont have to waste time with the Sony Ericsson update.

why don't you update via kies? it updated my 2.2.1 to 2.3.5 without any complains and it was really fast and easy.
And uninstalling/installing a program will not make samsung mad that they brick your phone for it, so no worries mate.

Flash a stock ftf via flashtool or repair your phone via pccompanion.
thanks so much for quick reply. I have one more question tho.
Do I have to use this flash tool: http://forum.xda-developers.com/showthread.php?t=1943886, or i can use official emma flashtool?

Any problems, just let me know
Yeah I cam vouch for that, find the ICS tft, if you look on the stickied topics at the top of the q+a section and use flashtool you will have no problems going back. Once you read it make sure that you use the .195 generic and then once booted do the ota. 233 . Format the phone once installed and all good.
Best of luck mate, there is plenty of people doing it at the moment until they bring out bug fixes for jellybean.
Any problems get in touch.

this version is not rootable right now, so if you count on root to do anything, avoid this one.
but if you are pure stock person, go for it, IT IS AMAZING, damn fast, damn smooth, never felt JB like this, NOR ON MY ASUS TF300T!
go for it if rot is of no importance to you

if it you could do it over the air, you MAY keep the root using ROOTKEEPER, but this way, using PCC or SUS , it's not possible to keep root...
as i said, if you don't care about root, go for it bro, it's easy to update, and the new firmware is just amazing
hope you enjoy your TX
or if you have unlocked the bootloader just flash a custom kernel with root.
DooMKerneL is my suggestion

You didnt understand. I said I cannot update it through Wi-Fi. Its saying "your device already has the latest available system update" but in PC Companion or PC Update Service says that update is avilable. Why my TX didn't got update notification?
or this update can only be done through PC?
by the way which method u used to update? Air or PC?
Maybe because it just realease a day from now.. So maybe.no OTA for now maybe a week or month will be available via OTA.. my brother accidentally update my xTX and i was pissed because i cant root it.. But the update has noticeable changes on performance.. Battery improves too.. But wifi thetering has its issue as i read someone posting it.. But for me i dont bother by that i dont use.it.. What bothers me is i cannot have root.. without root i feel my phone is less usefull for me.. But as the previous.post if your not rooted user definitely this update is good for you..

i DID understand bro, and what i said was just an explanation, for ANY condition, i meant under ANY condition, in future, it is impossible to keep root when you update through PCC or SUS, but you MAY keep the root using rootkeeper if you update via OTA.
it's normally usual that new firmwares are first available through PCC, not OTA, it's not weird..
I myself, downloaded the FTF file from Hong Kong, then flashed it via flashtools, you don't need to unlock bootloader if you want to flash a Sony Official Firmware
don't worry about anything, this update is just fabulous even without root, it's a BIG BIG performance improvement
let me know what you do, will help you as much as i can

seems like flashing the old kernel, having root, and then flash the new kernel won't do us any good, it keeps rebooting
and if you stay on old kernel, i mean Doom Kernel v07, so you are using the old kernel not the updated one which you actually looking for
it seems that there is still no way to have root with the new kernel righ away
Thank you very much :victory:

Getting warm after 5 minutes of browsing or gaming

I'm having the latest update 4.4.4,14.4.A.0.157 and C6903 version, so when playing even simple games like Candy Crush with WI-FI or 4G turned OFF, the phones gets warm.. also with Google Chrome browsing or Facebook.
Is there a way to solve this? I don't want to send my phone to Sony service, waiting weeks to get it back...
If root can solve, this how to root my phone? Never rooted an android phone so if possible I want some detalied informations about rooting and unrooting(I don't want to lose the warranty, sometimes I would want to unroot the phone). Saw some things with CPU settings that helps Z1 to don't get warm anymore, maybe you guys knows. Thanks!
well first if you can install a custom rom with LB
if i didn't solved your problem
i recommend you to use a custom Kernel but you need ulock your bootloder in order to flash kernel

Did it was confirmed that Android 5.0 will fix the heat problem at Xperia?
And does the link you provided works for the latest version of Xperia Z1 C6903 14.4.A.0.157 with the latest update 4.4.4 KitKat ?

Flash a custom kernel for the benefit of using some power saving CPU governors / IO Scheduler / battery life hacks & modifications..
