[Q] Rooting issues - 4.3, IMEI, not actually rooted etc.... - Xperia Z1 Q&A, Help & Troubleshooting

Hi All
So firstly I should say I only have myself to blame. I'm quite a techy guy so I just assumed i'd be able to root my phone without any issues and pick it up as I go. What i've quickly found out is i'm in way over my head and i'm an absolute noob!
Any advice would be greatly appreciated from those guys out there that actually know what they are doing. I have read many forums but i'm still lost.
My story is as follows:
- I have a Z1 that was locked on stock firmware 4.4
- I read that it would be a good idea to unlock the bootloader so i did this
- I wanted to root my phone but from what I read I could see I would have to downgrade the firmware to 4.2. So this is what i did.
- By doing this I lost my IMEI number, got very worried i'd ruined my phone. I tried many things to restore it, there were a variety of different solutions online, none of them worked. I eventually flashed a 4.3 firmware i found on this forum which restored my IMEI.
- I then read through a few posts of people who had similar issues and advice was given to downgrade again (if i wanted to root) but this time exclude the baseband etc. I did this, but lost my IMEI again! the advice didn't work
- So I then went and updgraded again! to 4.3 to restore my IMEI and network access
- There doesn't seem to be a way to root on 4.3 so my phone isn't rooted, that's ok. But when i try to use my banking apps they don't work! they say my phone is rooted even though it isn't! I have checked with root checker
- Like an idiot, i didn't back up the phone when i first started doing all of this, i didn't really know what i was doing so I am now in a situation where i have the worst of both worlds. They are, i can either 1. downgrade the firmware to 4.2, root my phone but not have a valid IMEI and network access or 2. stay on 4.3, have a valid IMEI and not be rooted but certain apps think i'm rooted so i can't use them.
So all in all i've just messed things up and i'm in way over my head. I would really appreciate some advice
Thanks

Yes you are right.
Also, there is no issue with losing IMEI when downgrading, it happens to everyone, but it comes back when you upgrade.
Also, if you unlock the bootloader there is no need to downgrade, that is a locked bootloader method of rooting
You should root before unlocking the bootloader in order to backup the TA partition, but you are too late now...
Solution
1) Use flashtool to relock the bootloader
2) Use pccompanion to update to latest firmware
3) Unlock the bootloader again with flashtool
4) Flash a custom kernel for stock based ROMs
5) Install SuperSU from the play store.
DONE!

The video by shem is for locked bootloaders, he needs an unlocked bootloader method

I don't think so, the unlocked bootloader method is very generic and there are hundreds (if not thousands) of guides and probably as many videos.

Hi Greg, can you give me a bit more advice please.
i'm just looking at the tutorial to relock by bootloader. It says "before u relock bootloader u have to be on pure stock kernel (flash only the kernel.sin using flashtool), else the device WILL NOT BOOT after relock"
The problem is i'm already flashed on to an FTF image that was on this site. From so by doing this am i going to brick my phone? i'm confused and i don't want to make things work so your advice would be apprecaited
thanks

You can't root this version directly.
You have 2 options.
1) Unlock bootloader.
2) Downgrade to 4.2, root via vroot then upgrade.
More details here.

You can always use nut method for upgrade but it doesn't support this version i guess.
or you can always go for a custom rom which is prerooted.

i know there is a method will sure work.
-use flashtool flash custom kernel
-go to cwm flash a zip file (update_supersu.zip) provided by someone in xda, credit to tat person!
-finally flash stock ftf with only kernel.
-done! rooted!
@chunlianghere, @thalada, What are you doing People? From all the links just one is correct, for .290. Also NEVER give advice to Unlock Bootlader because users cannot be aware of the risk doing this like lose Permanently DRM Keys and Warranty, FOREVER. Because if you do not advice of the risk someone can Unlock the Bootloader then lose DRM keys and if so it will NEVER be relocked and warranty will be void permanently, so before give advice learn what is all about!
@SpawnCube, the .136 cannot be rooted directly but can be Rooted with the method by NUT for Locked Bootloader. If your Model is C6903 you can downgrade directly to .534 with FW provided by NUT to not lose IMEI, then Root with Bin4ry, then Update to .290 with the instructions given HERE, when you have .290 rooted you are ready to update to .136 with the same method HERE.
For different Models the downgrade have to be done differently, downgrade to .257 FW First, then to .534 FW to not lose IMEI, but you will update anyway so there is no problem even if you will lose it.
Watch the Video Tutorial How To in the first Link for .290. It will explain all.

That sound like you try to be smart without know anything about it. So then you should go back to read the whole Xperia section before Post.
If you Unlock Bootloader you will lose DRM Key permanently and you warranty will be void forever. To avoid that You have to Backup TA, to Backup TA you need Root, but if you Unlock Bootloader before have root you will lose DRM. It is clear NOW?
I think only Samsung lose IMEI? Read again the whole Xperia section and Rooting Section.
If you love Samsung because is not so complicated then you are in wrong section.

actually i dont care much about DRM key anyway. send for warranty only if hardware is spoilt. the most ask them do last warranty repair.
if DRM key n warranty is so much important, than sony would hav "Bootloader unlocked: NO" for all phone in the world
actually sony doesnt do the warranty n repair. it depends on the company in tat particular country. like example for doomlord, his one is only flap damage, but can get 1 to 1 exchange. tat shows tat how good the company is in tat country.
unlocking bootloader n rooting is pretty much standard.
technology n software is improving at a fast rate. the most i get a latest newer phone.

Ok, here you are right but you have to understand that, what is not important you, it may be important for others, especially when we talking about Warranty.
We are here to give advice, then we should do this in the right way and inform users of any risk.

hey eclyptos, hope you still around this thread.
i quite agree with you, since i am one of those who care about warranty.
I hope it's fine to make a question about rooting here 'coz i can't make post on there. anw, i've been trying to follow the steps on here, but i find some trouble.
My status is :
Device : Xperia Z1 C6903
Build number : 14.2.1.136
what I did was :
Installing Flashtool 9.13 on PC
Download C6903_14.2.A.0.290.flashable.zip and put it on my first page of SDcard on device
Download C6903_14.2.A.0.290.Stripped.tft inside flashtool/firmwares folder on PC
Install TWRP on my device (can’t be used, root needed), can’t create a backup *step 5 failed*
XZDualRecovery Question : I’ve download it, connect my device to PC then enable USB debugging mode. Execute the install.bat from XZDualRecovery and choose number 2. Does anything really happened? *step 6 failed?*
Then I install the flashmode and fastboot drivers from flashtool folders. Tried to flashmode C6903_14.2.A.0.290 Brand Generic NCB but it stopped halfway.

The Video Tutorial on that thread explain very well what you should do, did you watched it?
You have to downgrade via Flashtool to .534 FW provided by NUT to not lose IMEI, Root the Firmware with Bin4ry, when you are rooted instal Dual Recovery, then follow the instruction to update directly to .136 from HERE.
All the files you find in .290 thread, Post #3, Watch the Video, then follow .136 thread.

My Sony Xperia Z1 C6902 is not detecting sim cards

Hi,
I wanted to root my phone but I was running Android 4.3 JB with firmware 14.2.A.136 - which, through a certain amount of research, found that is not possible to be rooted unless and until it is downgraded to the previous version.
Accordingly, I took the help of C4E Tech's video on youtube for downgrading my software from 4.3. I followed all the steps shown in the video using flashtool application. The firmware to which i downgraded was C6902_14.1.G.1.534_Generic IN.ftf as I live in India and mine is the 3g version.
However, on completion of this process, I found that my phone booted all right, but it did not detect my Sim card, and instead threw a status on the lock screen saying Invalid sim.
Request you to please help me ASAP as I am stuck with no way out and have tried all ways using flashtool application to fix this issue but in vain. Thanks in advance.
Also, when the flashing process was going on, a warning message was shown in the log, which said, this file is ignored simlock.ta, I dont know whether this has anything to do with what's happened. Please help

This is 100% normal. When you go from 4.3 back to 534, your IMEI shows up as all zeros. Just root 534, install recovery and follow [Nut]'s inductions for flashing his pre-rooted 136 ROM. After you do this your IMEI will be back and your SIM will work fine

However, how do I unlock my bootloader considering that my IMEI number's gone. Because to unlock bootloader you need to send the IMEI number to Sony right, after which they send a mail to me with a key. Can you please tell me how you unlocked the bootloader of your phone after facing such a problem??:crying:

Here you go: http://forum.xda-developers.com/showthread.php?t=2628185. A note: in the thread it says you must be on 290 rooted to do this. It isn't really true, you can do this if you are on 534 rooted. Just follow the same instructions. (To get from 534 to 290 rooted you do the same thing as you do from 290 to 136 basically, so you can skip the extra step and just go from 534 directly to 136).
Just wait until you're on the 136 rooted ROM and have your IMEI back and then unlock the bootloader. Just make sure you do a TA backup first!

But how do i flash 136 rooted ROM without unlocked bootloader ? I am very confused, please help. To flash a ROM, you need to have a custom recovery installed right ?, and for custom recovery to be installed, you need to have the bootloader unlocked right?, But i am unable to unlock the bootloader because of non availability of IMEI:crying::crying:

No, no, and no. All you need is root to install recovery. If you even did any research on the link I sent you would see that the recovery recommended says in huge letters at the top that it is for both locked and unlocked bootloaders.
With a locked bootloader you can flash any ROM with a stock kernel, which the one I linked has.

One click unroot?

I am facing a dilemma here.
I want to root my phone (probably using towelroot)
But sometime in the future I want to return it to the exactly unrooted state.
The problem is, for that,
I must unlock bootloader
Install CWM and backup my phone in case things go wrong
Maybe install a rom.
BUT.
If I root my phone, how will I go back to exactly the old stock state, because I am creating a backup 'After' rooting?
So If I restore using CWM, the bootloader remains unlocked and still rooted?
If i want to relock bootloader, I need root.
If I want to unroot I need an unlocked bootloader.
Im so confused. Please help.
That brings me to my qn. Any one click restore to stock?
Newbie, have mercy
Why will you unroot? (Or if you don't know exactly what it means: read, read, read and ask)
You can always go back if you flash KDZ file (unroot en relock bootloader -> see thread)

I thank you for the links.
But can you clarify 1 doubt?
How To backup your phone before rooting? (Because CWM requires an unlocked bootloader. An a to unlock bootloader, I must be rooted. Isnt it a paradox?)
Or must I root before backup?

If you read the links you'll get the answer at your questions.
In any case you don't need to backup before rooting.
Just read and understand all links plus this one "Frequently Asked Questions"

There is no danger in rooting, only the (wrong) use of root can be dangerous.

Hello all! Im new in xda forum, so i will be greatefull if you help me with my Sony Z1 phone. I have Z1 c903 on android 5.0.2., and I was mad on sony becouse they didnt make update to 5.1, so i was looking on forum how to root and install some custom rom and make my phone updated. So i find on some thread that i should unlock bootloader, and i followed instructions and unlocked it, but without making some backup or anything else. So i have seen that there is official update for sony and i want to get back to lock bootloader. But when i enter flashtool and enter "blu" i click on relock bootloader, and start phone type *#*#service#*#* it say that my bootloader is still unlocked. How should i get back to locked bootloader or make official update to 5.1. Please make it more clear becouse i am pretty noob for android development and rest.

I have Z1 c903 on android 5.0.2., and I was mad on sony becouse they didnt make update to 5.1, so i was looking on forum how to root and install some custom rom and make my phone updated. So i find on some thread that i should unlock bootloader, and i followed instructions and unlocked it, but without making some backup or anything else. So i have seen that there is official update for sony and i want to get back to lock bootloader. But when i enter flashtool and enter "blu" i click on relock bootloader, and start phone type *#*#service#*#* it say that my bootloader is still unlocked. How should i get back to locked bootloader or make official update to 5.1. Please make it more clear becouse i am pretty noob for android development and rest. Also i want to add that i have not rooted my phone or install some custom rom or other, i just have unlock bootloader and thats all. Could i get back my "DRM keys" and could i get back my ofiicial android. Thanks in advance.

oh dear, you lost your drm keys.... thats not good....all sony own camera features (bionz, noise reduction...) are lost now. So without your drm keys, you dont get an advantage of locking bl again. SImply flash official sony 5.1.1 and here you are
Tutorial?

[Help] Failed to root and cant boot but still can enter recovery mode.

Hello, Im really2 noob about these and just tried to root last night and failed, now my phone cant boot, but it still can enter recovery mode which is (CWM - based Recovery v6.0.4.7 so I have discover so many step and now become confused which one should I do, plus all the new terms I never heard before like flash rom, image, bootloader...
What Ive done since last night (after the problem occur) I download a ROM (maybe) which is http://forum.xda-developers.com/z3-compact/development/d5803-23-2-1-62-slim-t3127115
So I put it in sd and install the zip file through recovery mode I mentioned and reboot but still nothing happen..and also I do the same way to super SU.zip file, install it from recovery and yeah still like before cant boot, stuck at logo, just can enter recovery mode.
Hope any of you can help.
Sincerely, Noob.
Download stock firmware using XperiFirm and then flash that firmware with Flashtool,there is over 1000 guides on how to do that,and as well this will completely wipe your phone so if you didn't backup basically all of your data is gone.
Then try to root again,put recovery and flash that ROM.

I would stop trying to flash random roms while the phone still works and concentrate on following a proper guide on how to root and back up your TA partition.
You will need flashtool. Once installed look inside for a folder called Drivers, run the exe in that folder, this will give you flashtool drivers. If you are on windows 10 then installing these drivers is a bit complicated. You will also need Z3 compact drivers.
Follow the instruction on the above thread to downgrade your firmware to 23.0.A.2.93 or older. You will then be able to root very easily, then recovery and supersu are a couple of clicks away.
Once you have working recovery then you can choose a good MM build and flash that
Check that the rom you are trying to flash supports locked bootloader [STOCK] and if you are tempted to unlock your bootloader, then just take a minute to read through the Q&A thread bellow your question looking at all the DRM questions and why you'll never get your camera working properly again.

you need to place the firmware in c:\Users\%username%\.flashtool\firmwares
Then start the flashtool and it will show up
