[Q] How to downgrade stock 14.2.A.1.136 - Xperia Z1 Q&A, Help & Troubleshooting

Can somebody help me to install iHackers V2.1 over my stock 14.2.A.1.136.
I dont have unlocked bootloared and root.
I need fast replay.

Rooting on the newest version of Android 4.3.3 isn't impossible on the Xperia Z1, it just takes you more steps than normal to actually get full root access. I have a locked bootloader as well but I was able to get a rooted version of Android 4.3.3, specifically the iHackers 2.1 ROM running Android 4.3.3 with full root access. Here's how I got full root access on the iHackers 2.1 ROM:
1) Download the .ftf file named C6903 14.1.G.1.534 Global 1277-2880_R4A or the one provided by NUT from the compiled FTF thread at this link: http://forum.xda-developers.com/showthread.php?t=2469191
This is a version of the original Stock Rom that the VROOT program will actually work on when trying to ROOT your phone.
2) Flash the ROM you downloaded using Flashtool (steps on how you can go about doing that should be in the Xperia Z1 General forum.) and now, you're ready to root your phone with it.
3) Download, install and run VROOT to root your phone. Again, more information on how to properly root your phone using VROOT can be found in the Xperia Z1 General forum. For me, I just turned on USB Debugging on my Z1, connected my phone to my computer while VROOT was running and clicked the green button until I got root access. It's extremely easy.
4) With Root Access, now you can download and install Dual Recovery for the Xperia Z1 on your phone.
5) Download the latest iHackers 2.1 ROM from the Xperia Z1 Android Development thread and copy it to your phone. This is hands down, the best ROM for the Xperia Z1 right now in terms of battery life. With the latest 4.3 update, I'm able to get over 2 Days worth of battery life on one charge. Battery life is much better on the new iHackers 2.1 ROM running Android 4.3.
6) Download the flashable Locked Dual Recovery for the Xperia Z1 here. http://nut.xperia-files.com/
The file is called XZ-lockeddualrecovery2.7.63-BETA (or newest) .flashable.zip (8.48MB), download it and copy it to your phone, preferably the same place you copied the iHackers 2.1 ROM. To make things easier for yourself, create a new folder on your phone or SD Card in your phone and name it iHackers. Copy both the iHackers 2.1 ROM and the flashable Locked Dual Recovery.zip file into this folder.
7) With both files now copied to a folder on your phone, you're now ready to go into recovery to flash the iHackers 2.1 ROM. Boot into recovery and once you're there, do a Wipe Data/Factory Reset before Installing the ROM.
The rest of these steps are now taken directly from the iHackers 2.1 download thread on the Xperia Z1 Android Development forum.
8) Install the ROM and THEN Dual Recovery. Don't make the same mistake I did, once the installer is finished, DON'T REBOOT THE DEVICE. Uncheck the "Reboot Device" box and go back to recovery to install the flashable Dual Recovery.zip file that's in the iHackers 2.1 folder.
9) Switch Off Your Phone (Do Not Reboot). Select No to Disable Flash Recovery Confirmation.
10) Install Kernel.ftf for C6903 (.136) or Kernel.ftf for C6902 (.136) with Flashtool to get compatible Kernel and Baseband. To download the kernel.ftf file, go to the original iHackers 2.1 thread to download and flash the kernel using Flashtool. You should be familiar with Flashtool at this point since if you make it to this step, you've already used Flashtool once to flash the .534 baseband version of Android.
11) Reboot and Enjoy. Now you're running the latest version of Android 4.3 on your Xperia Z1 on a Locked Bootloader WITH full Root Access. Sure, it's not the stock version but the iHackers 2.1 version of Android 4.3 is just as good, if not better. This will certainly do until there's a better way to simply root the newest Stock Version of Android 4.3.

bricked my phone while installing custom rom.

Phone Details:
- Xperia Z (T-Mobile) C6606
- Firmware or Build 10.1.1.B.0.166
I was able unbrick my phone and hope the method I used is helpful to others.
****Here's what happened.....******
Got the phone from T-Mobile had a lot of useless apps. Tried to root the phone all kinds of ways. Connected the phone to PC and opened up Flashtool. Flashtool did not detect the phone. I had to go into USB debugging and uncheck it off and check it back on, phone was detected and it says Root Access Allowed.
Installed Dual Recovery.. and installed the rom from zip. Rom instructions as follow:
Requirements: (Click on link below to get them)
1. Root - You probably don't really need this since this ROM itself also include stable and proper root package but most locked bootloader phones require root access to install recovery.
2. CWM/TWRP Recovery support - This is the real requirements. If you can access Recovery to flash this ROM, the rest should be working fine like root/busybox. Sadly you'll need either root or get custom kernel with recovery so you can forget root and be done with.
Instructions did not say install a different firmware, so I am thinking I can use my original firmware since the rom was based on a stock rom.
After installation of custom zip, cleared dalvik cache and reboot the phone. The phone bricked on me. All it did was cycle through the sony xperia boot screen and restart over and over again. I couldn't even get back to recovery(pressing vol. down on reboot) to restore my back up of my previous rom.
*****How I unbricked my phone*****
Remembered back in the day when I was flashing roms for on my previous xperia... I use Sony Companion Suite to restore my phone back to factory. Luckily it worked for my Xperia Z and now I am back with the stock rom.

[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:

(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

Here it is:http://forum.xda-developers.com/showpost.php?p=51733368&postcount=423

Xperia Z not booting anymore

Hi People,
I'm new here and I do have a problem over, as the title says, my Xperia Z (C6603) won't boot up anymore.
Yesterday I unlocked my bootloader, I also rooted my phone and installed Cyanogenmod 12 afterwards using TWRP, this was working perfect and stable.
Today I found out my phone wasn't rooted at all after I installed Cyanogenmod 12. So I wanted to start over again using this way (http://forum.xda-developers.com/xperia-z/general/guide-how-to-root-10-5-1-0-283-t2872873).
So what I've basically done, I installed Xperiaz_10.5.A.0.230_kernel_only.ftf over the CM12 mod, after this my phone doesn't want to boot anymore, getting stuck at the the 'Sony' logo.
Tried to do TWRP -> Factory reset, but it didn't work.
Should I install a full .zip stock rom again instead of the FTF file to restore my old rom?
Kind regards,
xChillz
My root guide and the files provided there are for rooting the 2 stock roms in the thread title only.
You cannot flash a stock kernel onto a custom rom. This is why your device isn't booting.
You can get your device booting in a couple of ways:
1. Extract the boot.img from the Cyanogenmod rom zip and flash it using fastboot. This should allow you to boot into your CM12 rom again.
2. Flash a stock FTF. This will bring your phone back to complete stock. How to package and flash stock roms in FTF format

Thanks for the quick reply!
Could you tell me where I can get a 10.5.A.0.230 stock FTF or can I just Google it?
xChillz.
Thanks bro,
Installed the 10.5.A.0.230 stock FTF, then I installed CM12 and it works!

Stock ROM for Pre-root and installing Mx ROM V8.0.0

Hi everyone,
I'm interested on installing the ROM developed by MXNICE :
http://forum.xda-developers.com/xperia-z1/development/rom-z5mx-rom7-5-0extended-battery-t3224245
What I understand is that I'm gonna need a pre-rooted LP version of android, and I have lots of doubts....!
I have been working on rooting and doing some mods on my xperia z1 but only on KK...so I'm not experienced on LP
What I did in KK is: install version .108 with flashtool, rooted, installed CWM recovery, DEODEXed, Camera Mod, and other minor mods... and that is is what I'm using right now. I did not touch the bootloader so I understand I have locked bootloader.
Now, this custom ROM looks awesome but installation procedure is not clear for me. I have read all the entire thread (64 pages!), and I understand that I have to install this ROM through the recovery and doing a "clean Install"
Post #341 (by arvinaquio) on that thread is:
By the way, I did a very clean installation of this ROM by reinstalling .108. Rooted it and installed Dual Recoveries. Then created a pre-rooted .368 fw through PRFCreator then full wiped and cleared cache before installing the latest fw then power off, turned on the device manually then reconfigured(Unknown Sources, USB debugging) then rebooted to Recovery then full wiped and cleared cache and installed the ROM. Rebooted it and it turned on smoothly without experiencing any error reported recently from other pages. Always do a clean installation to avoid encountering error. Good luck guys and happy modding to all of us!

So now, I have to create a pre rooted LP stock ROM, I found the tutorial on the internet on how to do it, but...
1) My xperia z1 model is C6943, I understand it is compatible with C6903 (i lose TV function, which I don't care)... how can I be sure I won't have a problem if I put: KK .108 stock Custom AR for C6943, pre-rooted LP.216 Custom BR (.236 not available for C6943), and then flash MxROM which is Chinese C6903 ? (Edit: is Chinese C6903 version .236)
2.a) When creating the pre rooted LP .216 should I choose the same recovery (CWM) or can I use another (I want to change to dual or TWRP)??
2.b) And also I want to change from "superuser" to "SuperSU".? Can I make those change or should I stick to CWM and superuser?
2.c) If I can't, means I should start again from KK and root installing dual recovery and superSU?
3) Once I get the pre rooted firmware, should I install it over KK firmware using recovery or using flashtool? should I wipe data, cache, and dalvik ?
Of course I already did a backup of my actual system with CWM. I just want to be sure of what I'm going to do next and avoid bootlooping or bricking my phone.
thank you all !

3) the pre rooted firmware you get from prf creator is a zip file. This file is only flashable with the help of a custom recovery.
Don't mix up ftf files and zip files. Ftf => flashtool to get it on phone, zip => custom recovery to get it on phone.
So what I did Was: flash to stock Sony v. 108 firmware for C6943, rooted with easy root tools, download superSU from playstore and installed the dual recovery using install.bat file.
Then rebooted to recovery and made a backup.
When I flashed to lollipop using the pre rooted file I made, the phone went into bootloop. So I restored the backup and installed a pre rooted version that I downloaded from this forum, it was Central Europe for C6903. (in both cases I previously wiped data and cache).
Once I got lollipop working, checked it was rooted and with the dual recovery installed, I enabled USB debuggibg and allow install from external sources. Then entered recovery and made again a backup.
I previously checked that superSU and dual recovery included in the flasheable lollipop zip were the same version I used when I installed them on the stock kitkat rom, dont know if that was necessary, but just in case.
After that I entered recovery again, wiped data and cache and installed the custom rom.
It worked like a charm, and runs very smooth
