[Q] Unlocking Bootloader - Xperia Z1 Q&A, Help & Troubleshooting

Got a question about unlocking bootloader and the current state of my phone:
First up, this is the current state of my phone:
Bootloader locked
Rooted
Dual Recovery installed (??)
RomAur 4 installed
So basically the state of my phone is that I followed to guide in the RomAur post to install their ROM.
When I reboot my phone I get the extra buzz so I can hold Vol up/down to enter recovery.
I have root, but the sys partition is not mountable as R/W in RomAur 4 but I can flash zips in recovery.
I want to install iHackers v2 ROM and maybe also unlock bootloader as it seems all camera issues have been sorted (correct me if I'm wrong) (are there are reasons I should/shouldn't unlock the bootloader?).
What do I have to do to go from RomAur 4 to iHackers 2.0 with the current state of my phone? Should I bother unlocking bootloader to use a 3rd party kernel?
Are [nandroid] backups done in CWM any use at all as it seems that when flashing a ROM you then have to use flashtool to flash a kernel and radio so I'm guessing that the backups wont be able to restore these either?
Thanks for all the help and bloody hard work you guys put into developing for our phones.

As long as you save backs up on an external SD card you should be fine. I don't know what data you can restore back though. Photos, texts, apps, etc, should be okay. I'd back up with Titanium or something then just restore after. (I recommend nandroid also for your own peace of mind and hassle free experience)
Best thing to do is just do it from fresh to save you any hassle if you're going to wipe the phone anyway. It's best to wipe the phone before so nothing goes wrong.
http://forum.xda-developers.com/showthread.php?t=2539008
As it says:
Copy the ROM to External SDCard.
Install iHackers Advanced Stock Kernel.
Reboot into Recovery.
Make Sure to do a Wipe Data/Factory Reset before Installing the ROM.
Start the Installation. (Install Zip >> Choose Zip for External SDCard).
Switch Off Your Phone (Do Not Reboot). Select No to Disable Flash Recovery Confirmation.
Install Kernel.ftf for C6903 (.290) or Kernel.ftf for C6902 (.290) with Flashtool to get compatible Kernel and Baseband.
Reinstall Your Desired Kernel.
Reboot and Enjoy.

All camera issues sorted in iHackers v1.2.
Personally I'm running iHackers's PureStock.

If you want to unlock the bootloader, DON'T FORGET TO BACKUP TA partition.
You can unlock bootloader (after you have backed up TA), then install iHackers kernel, and go to Philz recovery (I believe it is volume up, but might be down), then click on wipe, then wipe for installing new ROM (or something like that), then install the iHackers ROM.zip

Why I should do that? With 4.3 still no problem unlock bootloader and I am already on 4.3 and I didn't backup anything. The only reason is Warranty.

To be honest I don't really have any 'data' on my phone that I would miss if I lost it... some photo's, MP3's.. I only do nandroid backups so that I can test a new ROM, if I don't like it or it doesn't work I can just go back to Recovery and restore the nandroid and continue as I was but that was on Samsung devices and I'm a little worried as to the usefulness of the nandroids on this phone. Why do we have to flash kernel and radio using flashtool and why can't they be installed with the .zip/ROM?
I have a backup of my TA partition; I did it as a step in rooting/flashing some other ROM but didn't really know why I was doing it but it's stored away for whatever reason I need it!
I think for the time being I'll keep a locked BL, but I want to get rid of this ROM off my phone. I really need /sys to be mounted as R/W and I'm having some WiFi issues with RomAur 4.

So far, you can't get /sys mounted as R/W with a locked bootloader, even on custom ROMs.
If you want full root, the only way is to unlock bootloader.

Dont think thats 100% accurate - you can get Root with /sys mounted as R/W on roms <4.3. I had iHackers (1.2 I think) working with r/w system partition I just got a little flash-happy when a 4.3 ROM came out and went and flashed it.
Doesn't matter now anyway.. I unlocked the BL! Flashed iHackers 2... what a pile of crap (my opinion)... installed a load of stuff I purposefully unticked in Aroma and has lost me root.. yay.
If I restore a nandroid of iHackers 1.2 from CWM will I brick my phone in any way seeing as I'm currently on Android 4.3 with all the kernels and radios that brings..? That is of course saying I can get into recovery...
[edit]
Can't get into CWM... brilliant. I guess I'm going to have to use flashtool to downgrade and root my phone or something like that now.. Wouldn't mind but I'm at work and have to download ROMs on my phone because of work proxies!

Yea, I meant it can't be done on 4.3
Well, Why don't you just flash stock ROM (4.3) then 257 then 534 and then install iHackers 1.2 without any problems.

Right, deleted last post but in summary; got root back but no Play Store and no recovery installed so did some good old fassioned searching:
Over in Original Android dev there is a discussion for Root on 4.3. The first post has links to kernels with recoveries and SuperSU by chainfire... downloaded Philz and SuperSU and now just need to figure out how to flash the two of them..
I take it something like
Code:
fastboot flash boot filename.img
will take care of flashing kernel to my UL phone so then I power on and press Vol Up, Vol down to enter recovery and flash SuperSU?
Wish me luck

Trying to install 4.4 Rom, falling at every hurdle.

Hi There,
Just wondering if anyone had any ideas why my phone refuses to co-operate!
Basically, after getting bored of the stock rom when I first got my phone, I somehow managed to install a CM based rom. That worked, but I got bored of the fact that the camera never seemed to work right, and some apps didn't work/ were graphically buggy. Assuming it was just a badly ported graphics driver or whatever, I found a way, using FlashTool, to revert to the stock rom (C6603_10.3.1.A.0.244_Generic UK to be precise). I wasn't sure exactly what it did, but it was back how it used to be. sorted.
So, since kitkat made it's way to the XZ, I thought I'd try one of those roms, being the curious bugger that I am. The process I ended up going with eventually was:
>Downgrading Kernel to a lower version because the root explot wouldn't work on 10.3.1.A.0.244
>Rooting using "DooMLoRD_Easy-Rooting-Toolkit_v18"
>Upgrading kernel to one that would accept a recovery
>Installing TWRP
>Booting into recovery, CWM appeared instead. Strange, I thought. Oddly, mount USB wouldn't work at all, so I had to boot the phone back up to transfer the kitkat rom over
>Trying to flash the rom gave me an error number 7
>Boot Loop, at which point I just flashed 10.3.1.A.0.244 again.
I've tried this twice now, first with DooM Kernel, and then once with a different one. Neither CWM or TWRP have worked properly. Any help? Or am I just cursed?
Cheers
Tried this again, did literally everything I could think of and still no dice. Help? Have I somehow forced my phone to be on stock software forever?
If you dont unlock your bootloader, you can not use any kind of custom kernel.
That means aosp or aokp based firmwares can not run over locked bootloader.
Locked bootloader checks sign of kernel, if not certificated you will stuck on bootloop.
If you want to use any kind of custom rom... basicly.
1. Backup ta partition. " so you can revert any time you want."
2. Copy firmware zip file tou your internal or external sdcard.
3. Flash custom kernel. "Most of kernel have recovery option build in".
4. Boot in recovery mod. "Mostly press volume down while booting"
5. Insall custom rom.
6.a wipe dalvik-cache
6.b factory reset
Old setting might work or not with new rom. So first try to wipe dalvik- cache. If you stuck on boot loop or any kind of problem, just boot in recovery again and run factory reset.

Hey, thanks for your reply!
I had unlocked the bootloader when I first got the phone and just assumed it would be permanent. Would flashing it back to stock firmware re-lock the bootloader?
But yes, assuming my boot loader is still unlocked ( I have tried to check and it doesn't seem to be locked) I have been through those steps basically. I am fine to flash a kernel with a recovery but the recovery never works properly/ at all. I can root the phone no problem though.
Best to extract the boot.img from the zip file of the ROM you want to flash, and flash that first. Then flash the ROM from its recovery.

Cheers, I'll give that a go - I was under the impression that you weren't supposed to flash kernels that weren't designed for the currently installed ROM though? It just seems that any kernel I flash isn't working properly so I didn't think doing that would play any nicer with the phone

You're not actually going to boot into your current rom after flashing the kernel.
Flash the kernel via fastboot, then boot into recovery and flash the rom.
All this should be covered in the installation instructions of whatever rom you're trying to flash in any case....
Sent from my C6603 using Tapatalk
Well, that seems to have done it! Thanks very much for your help.
So, I guess the moral here is that if you're on stock and need a recovery to flash a new ROM, always use the boot.img from the ROM you'll be using.
Thanks again - I'd never seen that said before but quite possibly I wasn't paying attention!

[Q] will i lose root while upgrading to 12.1.A.1.201 from 12.1.A.0.266?

Hi,
I'm currently running stock 4.3 (12.1.A.0.266). My phone is ROOTED, but have LOCKED BOOTLOADER. I have
My question is simple: will I lose root? Or any apps/data/sms/etc for that matter?
I just don't want to do all the stuff all over again. 12.1.A.0.266 is buggy but still is tolerable. >.>

Yes, you'll lose root if you update via OTA or flashing stock.
However, I think OTA does not wipe data, so you'll probably have your data. Do back them up just in case (can't remember since it's been a while since I last update via OTA ).
If you want rooted .201, install either of these roms:
http://forum.xda-developers.com/showthread.php?t=2704312
(v1.1 looks and works like 201)
http://forum.xda-developers.com/showthread.php?t=2658043
(v2 is a much "improved" version of the above)
I have installed the first one and loved it.
A few days ago I installed the second one and loved it even more.
Whatever you do, do a nandroid backup of your .266 (and preferably, add titanium backup of your apps and data/sms/contacts)
my mobile vibrating only after reboot!!!!!
My mobile was a rooted onewith .266 verson and i was trying to put the new rom and screwup!! ias you told i installe i downloaded the new rom v2 and super user,and dual recovery files... i ectracted from sd card all as you tol one by one ...while reboot...i saw sony logo and vibrating freequently only...not opening....!!!!!!!!!!! i tried to reset..same thing.....screwed up?!!!!!

Yup - screwed up somewhere in the process but no worries.
The process is almost the same way you got your .266 root.
To get new root and recoveries:
a. Flashtool - choose .257, then follow prompt to hook in your usb cable while pressing the Vol-down button
b. Once complete, close flashtool, unplug your device and reboot device
c. Once loaded and past the minor set up, turn on usb debugging and check "unknown sources" (all under settings)
d. Assuming you have all adb drivers installed (through flashtool installation), hook up your device to the PC and install Doomlord's exploit V18 and recoveries
Install new root 201
Boot into recoveries and flash the said .201 rom+SU+recovery (all zip files) using TWRP. Make sure you wipe cache/dalvik cache/data first. After flashing the zip files, select reboot from TWRP, and let the phone run a bit as it sets itself up (android and sony) during the booting process.
Note:
Ultimate purexsp V2.1 zip is simply an update file (not the full rom) - don't flash this one yet.
Somewhere within the thread you'll find the V2 full rom <663MB in size (as seen in my ext SD card). Flash this one and ignore the other versions

Congratz and enjoy the new fantastic rooted rom!

Need a bit of help, not sure what to do

So I was running Ultimate PureXSP v2.1 and it was starting to get really bogged down and slow so I figured id try and reinstall the ROM over the existing install, so I went into TWRP and installed it, the install said failed but because of the touch debug messages, I couldnt see the error message.
Anyway, TWRP has always had erratic screen movements and general weirdness, it would keep going back to the homescreen when trying to flash. So I rebooted and it got stuck in a bootloop!
I used flashtool to put a stock 201 firmware on and now its runnning okay again. But I have lost root and recovery and I dont think 201 can be rooted unless I downgrade first but I will probably run into data problems, I cant use titanium backup or a nandroid to back up my data.
What should I do? I dont have any backup software that works without root and I cannot root without downgrading and losing data.
Can I unlock the bootloader from 201 and then add recovery and root? I already have a TA backup and my unlock key.
Any help would be great!
Sent from my C5303 using XDA Premium 4 mobile app
Yup, that's what I did.
Unlocked the bootloader. Then can flash any custom kernel. I flashed DoomLord's Adv Stock kernel, which has an inbuilt recovery. Then flash chainfire's SuperSU update through recovery to get root. Then can install any other recovery and flash stock .201 kernel back. One problem though.. [highlight]YOU WILL LOSE ALL YOUR DATA (INCLUDING WIPING OF INTERNAL SDCARD) WHEN UNLOCKING THE BOOTLOADER.[/highlight] So, do you have any cwm data backup done before?
Edit: Backup&Restore app that comes with stock Rom is supposed to backup and restore data without root. But it never worked for me when restoring things. Other option is to use 'ADB backup' commands from a pc. It also didn't do restore properly for me. Can try those as last resorts.

Going back to stock from cm

how to revert to stock from cm. i dont have ta. please help asap.

am on unlocked bootloader. no problem ryt??
dosent matter mate.
I bought this phone, backed up ta partition, unlocked bootloader, installed cm11, then iHachers ROM 4.1 (with dual recovery - CWM and TWRP). How can I return to stock, lock the bootloader and restore ta partition? (make it like it was when I bought it)
When I backed up the the ta partition, I accidently deleted it, so i recovered the deleted file with Recuva. I only managed to recover a ZIP called TA-backup-20140717... .zip, which has 6 files in it. Is this the only file needed to restore ta partition and (it is 188 KB) is it corrupt ?
I know I should use Flashtool, but I do not know which FTF to select. If I restore the phone with Sony PC Companion, will the device get bricked? Because it is rooted with custom recovery and unlocked BL.
Thanks :good:

Pc companion will not even start to update your phone since it its rooted and bl uncloked.
Anyway, you need to flash FTF for your device (ex. C6903), best is Generic World latest one.

I didnt understand first one, so i will not answer to this, i dont want make any confusion.
Yes, if you flash everything your phone will become like new, and if you flash wrong "ftf" worst case scenario is that you will need to download new FTF and flash it again with correct one.

[Q] Few questions about unlocking bootloaders

I'm really sorry if these questions have been posted before but I couldn't find them anywhere. I am rooted on an Xperia Z1 C6902 with a locked bootloader. I have read that unlocking bootloader wipes your phone as well as sd card. So, here are my questions:-
1)I made a TA backup as suggested but I want to know what it will do when I restore it, will it be like a factory reset or will I retain my apps, or something else?
2)I backed up my apps using free version of titanium backup and I've read that it stores the backup on sd card. So after unlocking bootloader, won't these backups be deleted as well?
3)Is there a way to transfer said titanium backup backups to my computer for easy restoration later?
4)I've also read that restoring titanium backup while on a different rom will cause problems. Does this mean I have to start over if I get an AOSP ROM or Cyanogenmod(I really want one of these)?
5)Can I just take the sd card out of the phone while unlocking bootloader so that it's not wiped? Then restore apps from titanium backup?
6)Will unlocking bootloader using flashtool install a custom recovery as well?
I understand these are noob questions but please help me out I'm really confused
Please answer with the corresponding question number please
Sorry for too many demands/questions

1)when you restore the TA backup,your bootloader status goes back to locked,it will be like you never even touched the bootloader.But,the device wont boot up if you still have a custom kernel installed,so you have to flash back the stock kernel
2)I dont know about titanium backup
A better alternative is: Install XZDualRecovery(on locked bootloader) and make make a backup using your recovery of choice of /data(which contains all the apps/configurations/saved passwords blah...blah)onto the /sdcard.
Then unlock the bootloader and then restore the /data backup after.so everything including your apps and settings will be restored
5) as far as i know ,the sd card WON'T be wiped but you might as well take it out just to be safe
6)No,unlocking using flashtool will not install a recovery,the recovery is stored on the kernel(or not , if you flash a recovery image to the FOTAKernel Partition).

I'm really sorry if these questions have been posted before but I couldn't find them anywhere. I am rooted on an Xperia Z1 C6902 with a locked bootloader. I have read that unlocking bootloader wipes your phone as well as sd card. So, here are my questions:-
1)I made a TA backup as suggested but I want to know what it will do when I restore it, will it be like a factory reset or will I retain my apps, or something else?
2)I backed up my apps using free version of titanium backup and I've read that it stores the backup on sd card. So after unlocking bootloader, won't these backups be deleted as well?
3)Is there a way to transfer said titanium backup backups to my computer for easy restoration later?
4)I've also read that restoring titanium backup while on a different rom will cause problems. Does this mean I have to start over if I get an AOSP ROM or Cyanogenmod(I really want one of these)?
5)Can I just take the sd card out of the phone while unlocking bootloader so that it's not wiped? Then restore apps from titanium backup?
6)Will unlocking bootloader using flashtool install a custom recovery as well?
I understand these are noob questions but please help me out I'm really confused
Please answer with the corresponding question number please
Sorry for too many demands/questions
Thank you!

1) the TA backup returns the DRM keys to your default ( what you backed up) which means makes your phone untouched like its first day ( only about bootloader status,kernel,some DRMs like xreality and ... )
_____________________
2)the titanium backup , saves the backups in the folder TitaniumBackup placed in sdcard(internal storage). you can copy the entire folder in your pc or external storage to save it from deleting and put it back whenever you need it
sdcard/TitaniumBackup
_____________________
3) as i said in 2 yes. you can save the folder everywhere you want and replace it whenever you need your backups( u can also save just one or some of your backups if you want by saving the files in the folder)
_____________________
4)it depends on the app you are about to restore.. most of third party apps will not have any problem.even from device to device.. but the story is totally different for system apps
_____________________
5)yes you can do that..
_____________________
6)as i know,no.. it depends on your custom kernel...just flash a custom kernel and you will have the recovery:laugh:
and my friend! unlocking the bootloader it self, will not erase any of your data !! none of those! its a procedure that makes your phone able to accept and operate from a custem kernel instead of pre-installed kernel.. but if you change your ROM or flash a new ftf file(official roms from sony) , your internal and your personal data such as appdata,contact & ... will be erased . and you can select whether wipe the internal or not!(thats depends on your choice) and your ex-sdcard will be safe unless you select to format it!
and be very careful and good luck
Haha well I decided to go ahead and do it anyway
I got the apps and data back so nothing bad happened. I want to know how I can get clockworkmod on my device.
Android ROM manager says no official version of clockworkmod is supported for xperia z1. But then in a menu it also lists TWRP and clockworkmod as already installed on the system and asks if ROM manager can use those for its purposes. So that's why I asked if flashtool installs custom recovery as well.
Whenever I try to boot into recovery to make a backup, it boots normally instead. I hold down the volume up/down buttons and press them quickly on boot, the phone vibrates multiple times but no recovery mode, which leads me to believe there is no custom recovery installed, but ROM manager refuses to download clockworkmod and says there are two installed already! Neither of which can be accessed(if they even are on the system).
Sorry for this convoluted message
Any more help is greatly appreciated

To get a recovery on your phone,You have to A) Flash A Kernel using fastboot commands or B) Install XZDualRecovery
Since you have already unlocked your BL,flashing a new kernel would be the best option as it give you tons of new features like DoubleTap2Wake and Overclocking(or underclocking!!).Check out the android developement section for kernels and roms!

Could you please point out a thread to me that shows how to flash a custom kernel without a custom recovery in place?
Does this mean all xperia users have to install a custom recovery through commands?

All the kernels for the Stock Sony Roms for the z1 come with a recovery bundled in it(just basic cwm,not fun at all).I think some CM/AOSP based kernels lack recoveries(but i dont know for sure)!!
See,other phones have separate stock recoveries on dedicated partitions(only for software updates,no custom ****) and you can flash a custom recovery into that recovery partition and load it up.But sony....oh no...sony doesnt load a usable true-ish-recovery into its phones nor do xperias have a real partition for the recovery...so we have to get by with these tricks.....
Well the best you can do is you can install a custom kernel and then flash a recovery to the FOTAKernel partition.then the kernel will the load the recovery from the fotakernel instead.
