Not helpful with people for ICS, why would you do this when there are so many threads like this?

This can be helpful for anyone whose ROM isn't working. It is directed to noobs who accidentally ruins their custom ROM so they can start over. Also the reason why I'm doing this is because I searched the forums and I could not find a guide that was simple for noobs to understand, which would always work no matter what you did wrong. I've used this method so many times and it has saved me countless times. I thought the least I could do was to share.
I hope I answered your questions.

Why why why do People use uploaded.to links, and feel the need to rehost files to it. Just link directly to the flashtool and use mediafire for anything else.

I collected links from different guides/threads on youtube and xda and assembled them into this full guide. I did not bother to re-upload the files because I did not find it necessary though I agree, mediafire is really good. I will change flashtool link.

Thanks for taking the time to make this guide, sadly when I was a real noob I couldn't find any guide like this...

I understand this reply is far too late but for people in the future:
You cannot upgrade to ICS when your bootloader is unlocked. You can easily lock it again using this small FTF file. When the upgrade with PC companion is complete, you can continiue modifying your phone with custom ROMs etc.

It is very hard for me to know what is causing this problem. Some minor modifications to the flashing procedure can potentially fix it. Try doing it like this: Open FlashTool, drag the FTF-file and drop it in the dialog box. Press ok and wait for the instructions to pop up. When they do, connect the USB-cable FIRST to the phone and after that hold back key while plugging it to the computer. If the battery of the phone is too low I think it can cause problems, try to charge your battery (if possible) and try again. Also make sure to flash the appropriate FTF-file, accordning to your model.

Complete guide to rooting z1 compact

Can anyone tell me what is the correct process for rooting my z1 compact!!
The DoomLord's guide for rooted kernel says to get a TA backup first, TA backup guide says to get a root first, zxz0O0's guide for easy root tool asks for some tr.apk...What is going on 'round here!! >_<

Is everything wiped after root?
Hi Guys,
I need clarification/cofirmation here as I am in a spot of bother... Let's say that my Z1C was accidentally restored to factory settings and in the process I lost all contacts and messages.
I have now set out to try and retrieve them. After checking some software, which according to the developers, is capable of doing that it turns out that I should most certainly root the phone, otherwise the program(s) will not be able to search for this data (this information is virtually on every program's website).
Since my phone is still on warranty (and will be for some considerable time to come) I am not that eager to go all the way and unlock the bootloader. So my objective is to have root access with the bootloader locked. Now, I had a long read of the thread started by Darkimmortal on how to root Z1C without unlocking bootloader forum.xda-developers.com/showthread.php?t=2634196 and before I download gigabytes and take the plunge the milion dollar question is
DO I WIPE THE WHOLE PHONE IN THIS PROCESS?
I know that in the OP it says
Take a full backup, as all phone memory INCLUDING INTERNAL SD will be wiped.
Click to expand...
Click to collapse
but then we have a catch22 situation - need root to recover data, rooting will wipe all data
So basically is there a way to root the phone without loosing the data I am after?

This doesn't wipe anything.

HERE is the easiest way to root latest firmware.

Hey there, I could use some help with this whole root thing as well...
My Z1C is still on .108, but now all the tutorials seem to be for .157 and include flashing with a .108 stock rom???
So do I have to update my Xperia first, then flash it with an older version, root it and flash it with .157???
Some tutorials seem to be removed since they "don't work with the latest firmware anymore"...
Also how do I backup my phone before I root it?
Thanks.

I hope this helps...

Well let me help you both with this, since I have spent around three days wasting my time figuring out how to root the Z1C which appeared later on that I have downloaded the wrong files because the thread it self was providing the kernels for Z1 and not the Z1C. So this is what I did:
It is ok to update your phone to .157 so go on with it, when done make sure your phone isn't connected and is switched off.
1- Download Flash tool from http://www.flashtool.net/downloads.php. After it downloads install it and JUST IN CASE you haven't installed the Z1C drivers go to Your C: drive and click the Flashtool folder then go to Flash tool drivers and you will find the Flashtool drivers installer. Click and install USB drivers and Fastboot drivers, scroll down and select Z1 compact drivers too.
2- Download the two required Z1C kernels and the RootTool as well from http://d-h.st/M9a make sure you Click the DOWNLOAD NOW button not the upper DOWNLOAD button because it is just a useless malware!
then place the two .ftf files in c:/flashtool/firmwares folder. Make sure you place the two '.ftf' files that are in the .zip in the firmware folders you can download them from the attachment too below.
3- Open the flash tool, Click on the flash button (top left) and choose the Flashtool method where you will find the two kernel files you placed in Firmwares folder.
4- Click once on the .108 Kernel and click flash, AFTER THAT press the volume down button on your phone while it is switched off and connect it to USB and wait for the Flash to start and end, it will take several seconds.
5- once it is done disconnect your phone and restart it by simply switching it on.
6- Unzip and place the rootkitXperia_20140719 folder better on your C: Drive. Connect your phone and run the tool by double clicking Install. bat (it might show only install as a name) and keep watching your phone screen to approve. Wait for it to be done and then restart your phone, then switch it off.
7- Follow the same method above to install the .157 Kernel again to your phone and you're done!
PM me if you needed anymore help. Sorry if my guidance is complicated a little bit, just let me know.
All the best!

Thanks for the help. I did however just root my .108 now because I really, really didn't want to unlock my bootloader and flash the kernel.

You don't need to unlock your bootloader to flash kernels or root.157

Really? Damn, must have misunderstood some of the guides. Thanks for the hint.
It's just a load of information at once, and this is my first Smartphone, so I didn't want to go overboard.
Is the .157 update even relevant in any way? And now that my phone is rooted, can't I just flash .157?

I think if you flash .157 you will lose root and will have to reroot by the method I mentioned.

I have D5503 with .157 Will I loose data using this method? If yes, is there a method to root the phone and save all data (including game saves, settings and everythink)?

No, not if you flash 108 kernel, root then flash 157 kernel back with flashtool.

When I run rootkit, it says "Waiting for device". Mobile is connected with PC companion. I have tried to install drivers, tried to change phone connect mode.... Do not know what is a problem. I do not have SD card in my device.
OK passed the "Waiting for device". Now stuck on "daemon started successfully"

So problem solved. The only problem was that the phone has hidden developer options where is USB debbuging. There is a little trick to open developer options so I have enabled USB debugging and than root works.

successfully rooted xperia z1 d5503 4.4.4
@emiratesson thanks i followed the instructions that you gave. At first im having a problem in flashing the 108 because my pc companion is ON im getting errors. I noticed that even though i flash 108 i still have firmware 157 because my current FW is 157 no changes and i tried to root it using rootkitXperia_20140719 still in 157 and a SuperSU app was created in my phone i guess that is the root app.
Current Build: xperia z1 d5503 4.4.4 firmware 157.

[Q] Restore Z1 Compact to stock firmware before sending it for warranty repair.. help

Hello XDA!
I've ran into some hardware related issues with my Z1 compact (the earphone jack is glitchy) and i want to send my phone in for repairs.
The thing is i have a modded cyanogenmod firmware on it as i preferred it over the stock rom. I also have that clockword mod thing.
As you can tell i'm not very accostumed to doing these things and i was wondering if anyone would guide me on how to restore the phone to its original stock setting?
The phone is a swedish device so i would need the scandinavian versions i'm guessing, any ideas out there?
Thanks.

You just need to find the right firmware for your region / provider.
I would recommend IaguCool's thread on Xperia Firmware Downloader & Checker, if you have flashtool installed you can make your own ftf that is exactly right for your phone. All the instructions are in the thread.
Hopefully you made a copy of your TA partition before you unlocked it and put CM on your phone? it may not matter if you have not, as long as it looks stock.

If you didn't do it, then it won't be saved anywhere on the phone. You have to physically copy it to the hard drive of your pc for safekeeping.
It doesn't matter, it won't stop you from restoring the stock rom and I don't think not having it voids the warranty. Maybe somebody could correct me on that?

Definitely didn't do it then. Hopefully they won't give me any trouble for rooting it, it's worth a shot anyway.
I've downloaded the firmware but it doesn't come in the same sort of package as cyanogenmod, are there any guides you can recommend on how to apply this firmware to the phone?

and don´t forget to relock the bootloader with flashtool!

You'll need a copy of flashtool and the adb drivers.
Flashtool will turn the downloaded files into a tft file, but all the instructions are in the thread.
If you get lost then XperienceD's AIO thread will guide you in the right direction

I downloaded flashtool from sonys website and it actually listed stock firmwares in a list which i could apply to my phone so i did.
Now the phone boots into what seems to the be stock firmware, however i was going to go into recovery just to check that was restored too and not the clockworkmod i had previously installed but it seems i cannot boot to recovery anymore, what can i do? Where can i find the "stock recovery" that these phones comes with? I want the phone to seem as it was never rooted/changed on the software level

You have flashed the Sony rom, so now it is stock, with no root or recovery. There isn't a stock recovery. Your work is done.

Isn't there a menu you can boot to that gives you the option to wipe cache partition and do some various other stuff? Perhaps this is only for samsung devices, sorry for the confusion and thanks for the help!
Hopefully the service goes as planned!

Is still the way to do it or is there any new ways ?? I have bought a Z1 Compact for my son who is 8 and he wants it back to stock. It has CyanogenMod now.....cant recall what version though since i dont have the phone with me.

Question No Software update available Globaleea-a2 - user

Hi,
It seems like there is no update for my device, since I bought it. I have checked manually on the phone and in Xperia companion as well.
In general I am not really interested in updates, but as I read the "Green tint" issue is solved by software upgrade, so it would be great to have it.
These is the current one:
Phone software revision:
62.0.A.3.28
GLOBALEEA-A2 - user
I also don't know what the "-user" means here. As I see other forum member got the update for GLOBALEEA-A2 (without the "-user" if I understood well).
Is it something I can do for getting the upgrade, or should I just wait (I am aware of upgrades can come later for different CDAs)?
Thank you in advance.

I would recommend you to try reflashing your phone via Sony's official flashing tool Emma. It does often help with software-related problems such as this.

Thanks,
I will do so.
Is flashing with Emma voids warranty? Is it deletes user data (like factory reset)?
Thanks and Merry Christmas

You need to unlock bootloader which voids the warranty. So unfortunately yes.
But you can always relock it afterwards which may make your warranty show as non-void.
It does delete all user data as you are flashing the firmware and overwriting the full storage.
Happy holidays.

First you can try Xperia companion, if that doesn't work you can use XperiFirm to download the firmware and then use Newflasher to flash it. You should remove persist file from the firmware before flashing. This method requires no bootloader unlock.
Otherwise there's EMMA as mentioned.

Thanks, update works after repair software

The same to me, I bought an Xperia 10 III directly from the Sony store, that is no brand, with software version 62.0.A.3.28 GLOBALEEA-A2 - user. I tried several times to get updates, both from the device and from PC (Xperia Companion), with no luck.
At the end, I backed up the phone twice, first time manually connecting it the my PC, second time via Google One, than I used the Xperia Companion to make a Software Repair, now I have 62.0.A.3.163. This way is rather boring since I had to manually re-set several apps, which weren't correctly restored from the backup(s).
I hope I will able to get updates in the future, if this is not the case I will try the XperiFirm + Newflasher way in order to try to keep my data.

I've flashed the 10 III and 5 II (using Newflasher) for the same problem mentioned here in the thread, unfortunately. Many Xperia are afflicted by this problem with no OTA updates and i don't know why.

For me, re-locking the bootloader helped. It is possible that the unlocked bootloader is blocking updates.

According to the Newflasher thread on XDA you will lose attest keys if you do, which might affect functionality.

really thanks guys. I'm not an expert in the modding, and every info can help me to better understand the situation.
What can i do to see if the Bootloader is locked/unlocked on my Xperia? There is a code to put in the dialer perhaps?
