If installing a custom rom, follow the guide from the rom developer. A no-system file is just the firmware with system partition removed, reason for it is decreased (a lot) file size and less errors noobs can make.

The easiest way to use root and custom roms is with unlocked bootloader, yes.
[Xperia Z1 Compact General] lskyr3l:
I got the same problem. How can i avoid it?
[Xperia Z1 Compact General] Nikito27:
same problem here!
[Xperia Z1 Compact General] zxz0O0:
Check hashes. If the hashes are correct, uninstall flashtool and remove the folder C:\Flashtool (save the ftf files). Then reinstall it.
[Xperia Z1 Compact General] Nikito27:
they are correct, but stil not working
[Xperia Z1 Compact General] camaro322hp:
Thanks for this guide zxz0O0. I finally got up the guts and the time to do this, and it worked great the first time. I would fall into the noob category here, but it was fairly straight-forward. Took about 45 minutes start to finish. One small glitch around step 14, somehow the driver got hosed up along the way and my computer wouldn't recognize my phone when connected, so I had to uninstall the z1f driver from device manager, and then re-install the z1c driver in device manager. After that, smooth sailing.

Thanks again zxz, great guide. :good:

What firmware is installed?

Hello,

I want to unlock and root my z1c and so I have found this guide.

About the older firmware to install (to unlock the phone), I've seen there is a UK version but alod De and FR versions.

I'd like to know what version is on my phone right now, where can I find this.

The only thing I can find in 'about the phone' is the buildnumber which is 14.3.0A.0.757.

I live in Belgium, I ordered the phone in the Netherlands and the phone was delivered with user guides for Hungary, Bosnia and Serbia, so I don't know what country I will have for the firmware.

Hi all,

i got a question plz. i just got a brand new z1c and i want to root it, but just root and nothing else. no recovery, no other kernel.

i have last firmware installed.

can you plz tell me, if only installing Z1C-lockeddualrecovery(...)installer.zip (point 14 from guide) and then super su it is enough to have root?
[Xperia Z1 Compact General] coolkoushik07:
Without dual recovery u cant mount system partition as rw.. That means ur root is pretty much useless with any recovery..

If anyone can help me ...

How do I unlock the bootloader Hisense E860

Or how to change splahscreen?
[Xperia Z1 Compact General] gpietron:
many thanks for the guidelines in this thread - and to TQuest for files in post #146 - rooted, TA backed up, bootloader unlocked. TQuest's JB files tested.

All this to try KK and find out that for now I am happier with Sony JB ROM, plus Xposed and GravityBox & MinMinGuard installed.

Sony added some nice touches, for example to Email app (thread view, tasks sync etc.). Also, I have a problem with corporate mail in KK, in which Contacts/Calender sync initially but then periodically get reset and re-sync from scratch, don't know why (had the same issue on HD2 - let me know if anybody knows why or a workaround ...).

The only mistake I made with the guide was to force shutdown of Z1C after successfully unlocking the bootloader, before disconnecting the cable. Got a bootloop afterwards and had to repeat the whole procedure once again.

cheers,
[Xperia Z1 Compact General] TQuest:
thanks for the feedback, i did test the D5503_14.3.A.0.681_EURO LTE.ftf firmware but never really used it, because it was know to be full of bugs,

i also made a version of D5503_14.3.A.0.757_EURO LTE.ftf that i like and use. however, i didn't upload it because i thought sony would release an update after just a few weeks like they did with 681 and 757...

if you are interested in that version let me know and i'll upload it.
[Xperia Z1 Compact General] gpietron:
thanks for the offer, yes I might try it to see if my corporate Contacts/Calendar sync issue would still exist. They are breaking on KK for some reason - probably not a fault of Z1C ROMs (the same was happening on HD2). Not immediately as all working very nice, but I might test it in free time during a weekend :) .

I have the phone rooted and also Philz touch 6.0.4? Could a backup done with philz be restored if I mess up the update to 757 firmware? Would it put my phone in exactly the same state as when the backup is made. Reading here I saw that some people had problems restoring?
[Xperia Z1 Compact General] darkmystel:
I'm now totally screwed :/

Wasn't able to flash super su

Then I tried wipe which was showing data wiped but unable to do anything with mounts n I tried reset which also failed n rebooted now all I see is Sony n no led lights even
[Xperia Z1 Compact General] isimsizkullan:
is flashing the stock rom (ftf) via flashtool enough for the unroot and stock recovery?
[Xperia Z1 Compact General] zxz0O0:
Generally, yes that's what the backup is meant for. But I made a backup on Philz and it gave me an error on restoring data partition so I advise you not to use Philz for backup.

Restart from the guide.

Yes.
[Xperia Z1 Compact General] mihaid:
What should I use then?
[Xperia Z1 Compact General] zxz0O0:
You can for example use TWRP recovery. If you're using dualrecovery, you can boot into TWRP by holding Volume Down (instead of Up).

Yeah I was trying that only :p after a while only I found that the USB cable wasn't connected :p :D

There was a contradiction between the video and the audio and the overlaid instructions

at 4:28 the C6903 file downloaded from the link from video did not have any entries whatsoever in Wipe window so I could not untick anything, flashed it anyway.

at 2:26 the caption says z1c 44 uk flashable but on the screen you can see z1c 44-14....757 uk flashablezip. being copied to the sd card. I had a copy of 757 from somewhere else so I flashed that not z1c44 uk.

Please help
[Xperia Z1 Compact General] zxz0O0:
Yes, it worked perfectly. Somehow I lost my content on internal sd card (photos, videos), not sure if that's related though.

I advise you to upgrade to a rooted stock firmware following this guide: http://xdaforums.com/showthread.php?t=2688933

It's best to take the same firmware as you made the TA backup (e.g. if you used 4.3 to take TA backup, flash 4.3 now). Then restore the TA backup with the program Backup TA to lock your bootloader.
[Xperia Z1 Compact General] kezown:
Thanks for helping me out with this but following that link just makes me even more confused (because it has links within links and I am a total noob when it comes to flashing phones). I went to this link because I have an unlocked bootloader with CM11 on it:

hey tried the easy root tool both in Mac and windows ,in Mac it says ALL DONE,DeVICE REBOOTING but it doesnt reboot or anything,in windows partion it say 'The system cannot find the path specified'.

what am I doing wrong ? Does the phone needs to be in normal switched on mode or any other?
[Xperia Z1 Compact General] zxz0O0:
You should be using the latest version (currently v6). It never throws the message you're describing so you are doing something wrong. Phone needs to be booted normally and then just run the tool.

The screen can be unlocked! Thank you anyway, at least you took the time to respond and mock me! :p

hello sir, I'd like to ask your help

anyone can tell me how to unlock after relock bootloader without TA :(

I've succeed unlock through FT but it's said bootloader status "unknown", I've lost my mac address too, doesn't work when flashing custom kernel too...... but when I relocking again through FT it's succeed and I gain my BL locked again with mac address working
[Xperia Z1 Compact General] EpicLPer:
Stupid question now but: How do I get my Z1C completely back to a "like out of the package" state so I can send it in for warranty?

Story: I made some underwater photos/videos and on the 3rd day of doing so (never had it more than 30 minutes or 1,5 meters under water) water leaked into the phone somehow, not trough the lids, checked them many times AND also checked them if they are wet after I saw the issue, they werent leaking.

Anyways, as said, I want to completely go back to the beginning like taking the phone out of the box. Now, how do I do that? What are the steps for this? Do I have to flash the stock ROM first? If so how exactly? Because as I think restoring the TA Backup first won't let me flash anything else anymore because of the locked Bootloader.

Thanks many times for replies already! :D

(Also if possible please really make an easy step by step instruction, it not only will help me but also future guys having the same problem :) )

PS (Edit).:

The phone still fully works, but one part of the Touchscreen doesn't anymore. I can still use an USB mouse tho, no problem there!
[Xperia Z1 Compact General] zxz0O0:
1. Flash stock firmware you used for TA backup and root it (e.g. if you used Jelly Bean to take TA backup, flash Jelly Bean)

2. Restore TA backup with Backup TA (this will also relock your bootloader)

3. Flash stock firmware (preferably from your original cust# but it's not so important) and check wipe everything
[Xperia Z1 Compact General] EpicLPer:
Is there any way to verify what version I used for the TA backup? I mean I'm 99% sure which one I used, sure the latest one, yet I just wanna be 100% sure to not buck things up ;)
[Xperia Z1 Compact General] zxz0O0:
Go to Backup TA folder, open folder backup/ and extract your TA backup. Open TA.img in hex editor (or text editor probably also works) and search for "NEW_VERSION" (first occurence), shortly after that there should be "fs_version:" (e.g. mine is fs_version:EURO-LTE_14.2.A.1.114 => so I would use 14.2.A.1.114 to restore my TA backup)
[Xperia Z1 Compact General] EpicLPer:
Wow, thanks for the fast reply! I'll do this now :) Have some "Thanks" from me! :D

---------- Post added at 08:57 PM ---------- Previous post was at 08:40 PM ----------

One more question to this tho: With Step 1 do you mean flashing it via Recovery (ZIP) or Flashtool? Because Step 3 is the same. Also "cust#" confuses me a bit right now, sorry :eek:

After messing up several times I managed to get everything right with the root and TA backup. I had to use the work around to install the recovery manually since install.bat failed.

Only remaining problem is that Google Play keep giving me a 403 error and refusing to download anything. I've tried removing my account and clearing the apps, but no success, I still can't get Play to download any apps.

I'm using a Swedish Telia one.

Try flashing it again. If it doesn't work you may try on a (physical) Windows machine.

And check the file hash it should be:

It was exactly like described in in this post discussing the other guide. Now thinking about it, I might have mixed up the downloads from the two guides. I assumed the files downloaded properly, since everything else seems to work.

Thanks for the tip. I'll give it a try.

Edit: Fixed it. Got the suggestion to name my new phone in Google Play's website and that did the trick. Instant working downloads...

A bit of problem as well guys, My Win 7 says it's unable to install the MTP drivers for the phone at step 13. Consequently, I cannot move on now.

Edit: Changed USB ports and it worked.
[Xperia Z1 Compact General] zxz0O0:
Yes. After you get the confirmation that your device is rooted, power off your phone (unplug from usb and make sure it's off).

After the phone is off, you start it again in flashmode (hold volume down and plug in your USB cable). Then you can continue with step 15.
[Xperia Z1 Compact General] avec_style:
Do I need to put all the necessary files on an SD card? (don't have any with me at the moment)

Or can I just put the files on the internal memory?
[Xperia Z1 Compact General] zxz0O0:
It might work on internal storage but I think you'll have to do it after step 9 then. Please report back if you tried.
[Xperia Z1 Compact General] avec_style:
Maybe I still can get an SD card before I start rooting. If I don't I will let you know.

In the Meantime I have another question. What if something goes wrong in the middle of the proces? How can I get my device back to its old state?

(Do I need to make some backup? and how should I do it?)
[Xperia Z1 Compact General] zxz0O0:
What do you mean with 'old state'? Your data will be wiped during the process. If you mean by 'old state' the firmware you had when you bought the phone you can look here http://xdaforums.com/showthread.php?t=2631291

If the firmware you have is not in the list, there is a method to create a flashable ftf of your firmware: http://xdaforums.com/showthread.php?t=2311211 and http://xdaforums.com/showthread.php?t=2188129 (first one is easier, but might not work).

Even if you do something wrong, you should still be able to get in flashmode (I had to start 3 times again because I did some steps wrong).
[Xperia Z1 Compact General] avec_style:
thanx, that was usefull info that I needed.
[Xperia Z1 Compact General] munjeni:
There is a better solution to restore your stock rom. Steps is:

adb push busybox /data/local/tmp/

disconnect usb cable

open terminal emulator and do:

cd /data/local/tmp

chmod 755 busybox

./busybox tar pczvf /storage/removable/sdcard1/system.tar.gz /system

now you have full system backup in your external sdcard. Ater rooting, simple do:

cd /

busybox mount -o remount,rw /system

busybox tar xzvf /storage/removable/sdcard1/system.tar.gz

reboot

done :)

Another thing. Any one confirm - current rooting status is safe??? Are you 100% sure??? Did you checked bootloader version, version of the other things...etc, are you sure something is not broken by flashing xperia z1 firmware, for example did your phone got touchscreen firmware flashed from z1, any strange thing after all that...???
[Xperia Z1 Compact General] zxz0O0:
I haven't noticed anything bad.

In software info it says:

S1 Boot Version: 1270-3115 S1_Boot_MSM8974_LA1.04_15

Touch Firmware Version: e

I have unlocked the bootloader btw.
[Xperia Z1 Compact General] :
Step one is giving me trouble. Here are some problems I found:

- I can easily install drivers without an exe file, but the instruction doesn't mention which device should show in the Device Manager. It's showing 3 devices without drivers for me here, but none of them will accept the drivers downloaded from Sony.

- The phone shows up normally with drivers installed in the Device Manager and Windows won't replace them with the ones from Sony's site, saying that the best driver is already installed.

- Because the computer recognized the phone, I assumed this step wasn't really necessary and didn't find anything on the instructions saying otherwise.

I am using Windows 7 64bit. Every other step worked until I hit step 13, which doesn't work because now the program doesn't find the phone, even though Windows keeps making that noise whenever I unplug and plug the phone back in. What can I do from here?
[Xperia Z1 Compact General] zxz0O0:
I don't remember anymore what the device name is, I think it was just D5503.

It's weird that your phone is not recognized in step 13, what you can try though is that you plug in your phone to your computer after step 10 (after you enabled usb debugging) and check that the device is recognized (also check device manager).

And try changing the usb port.
[Xperia Z1 Compact General] moesus:
Rooting and backing up TA-Partition went fine and everything works perfectly. Now, just a quick question. When Sony brings out the 4.4 Update, will I be able to update OTA (with a locked bootloader btw) and if so, will it undo the root access??:confused:
[Xperia Z1 Compact General] zxz0O0:
As far as I know you can do it OTA (not with an unlocked bootloader though) and yes I'm pretty sure it will unroot the device.
[Xperia Z1 Compact General] :
It only took me a total of 8 hours of frustration, but I figured it out. I did all steps before installing the recovery at least 10 times until it finally worked. I think one of the many roms and USB modes made the computer install the necessary drivers somehow. I noticed that the recovery installation did recognize my phone, but it takes some 15 to 30 seconds after hitting 3.

My next problem was that CWM, for some weird reason, did not have access to the internal or external storage. It kept saying "can't mount /sdcard" and there was no way around it. I eventually decided to try holding volume down when booting and using TWRP instead. From there, everything worked fine. I was able to format /system and flash the other files without problems.
