will it brick? soft or hard? - Xperia Z1 Q&A, Help & Troubleshooting

hi to all xda members, just want to ask something i am just curios.
i have this device with firmware .108 and upgraded to .157
what i did was at .108 i rooted and and flash dual recovery then after i connected to wifi a system uodate is available so i updated the fw, and that time i didnt lose the root so now i am on .157, so what i did is back up the system with .157 fw.
my question is if i reflashed to .108 [downgrade] rooted it and with dual recovery, is it OK if i restore the .157 fw although i am currently on .108?will it brick my device?

No Signal/IMEI After Flashing PAC Man Rom

I have searched countless of Forums and gone through Google alot and i still havnt found a solution yet, but coming from Stock Rom C6903_14.2.A.0.290 with Unlocked Bootloader and flashing PAC Man Rom in CWM succesful, but as soon as i get into the Rom, theres no Signal and i also checked my IMEI and it just says 0000000000...?? Is there anyway to restore the IMEI number to get the signal back somehow, or do i restore a Baseband or TA from another Stock Rom to get the signal/IMEI back..???

My Xperia Z1 encountered the same problem after flashing C6903 14.1.G.1.534 Generic UK 1276-0875_R9A. The IMEI was changed to 00000000000000.
Here is the solution: Flashing C6903 14.2.A.0.290 Generic AU 1277-0078_R2B via Flashtool will restore IMEI (I got back IMEI)

If you use flashtool to flash 4.3 ftf you will get problems like not having signal after flashing previous version (4.2) and the solution that worked for me is to reinstall software using SUS. After that I was able to get signal when flashing 4.2

Hi all,
Same problem here : upgrade to .290 and install the PAC ROM, the install is ok but no IMEI (so no connectivity). Is anyone know how to solve without losing the rom.
If I flash the original/stock ftf, it works again, but it's not the PAC ROM, so 1 win for 1 loss.
Thanks
Android 4.3 obviously changes something in the phone so that if you jump to another version it won't get signal or IMEI.
Anyway, the solution is simple.
Flash 290 and then 257. You'll get the signal and IMEI. If you want, you can go to 534 from 257 and then flash any ROM you want.
P.S: you don't have to flash 534, but you can do it if you want.
@Just2Cause
I unlock my BL so if I downgrade to 257, the camera will work or it will have the same "bug" as the 4.2 FW. after flashing to 257, do I need to stay on a 4.2 FW to keep the IMEI or can I flash the PAC ROM (which use a 4.3 FW) ?
Also, when I did the upgrade to .290 I use the sony companion app and it gave me no probleme (IMEI, call, sms was ok) it's specifically the PAC ROM that reset the IMEI. So I wonder what differs at low-level between the stock .290 and the PAC ROM, that can affect the IMEI
Tks
Download any .ftf (GENERIC is recommended) flash it using flashtool, and download the .ftf kernel for that specific ROM that you have flashed and flash it also using flashtool. i had the same problem downgrading from .290 to .534 i forgot to flash the kernel for .534 so i was stuck with IMEI 000000000.
Cheers

It's not the PAC ROM that resets your IMEI, I also got same problem when I downgraded from 290 to 534.
I'm afraid that you will lose camera (not sure, just maybe) after downgrading you will be able to install PAC ROM without any problem.
There must be something in Sony 4.3 firmware that needs to be ported to other ROMS so the camera gets fixed.
I got it working!
IDK if you guys have figured it out yourselves but here is what I did...
After unlocking my bootloader on .290 I flashed the latest nightly build of PAC-man. Same as you guys My IMEI number was 000000000.
So what I did was flash [NUT]'s .534 ftf for downgrading to 4.2.2 (found here: http://nut.xperia-files.com/files/C6903_14.1.G.1.534_[NUT].ftf.torrent) which brought back my IMEI number!
From there I rooted my phone again, flashed the boot.img for recovery, flashed the latest build of PAC-man and tada! Everything is working.
Flash the latest firmware(.757), flash doomlord's advanced stock kernel(not the main one), flash the rom of your choice from there that includes kernel (like PAC) and now it REALLY is working.

On nut.xperia-files.com there is no 534 rom for c6902 its only have c6903
Is it fine if i flash C6903_14.1.G.1.534_nut to my c6902...
I also have the problem with network. Not with this particular build, but with all AOSP roms. "Formatting boot, system, cache, data, and everything you see" will help my phone not recognizing (or invalid) sim? Are there network drivers I can flash from zip? Sorry for asking this, but I don't want to flash again and spend 3+hours figuring stuff out and then finding out later I can't call.. I need network to work as calling is what makes my device a phone, not a tablet. Help would really be appreciated.
I've used...

-Paranoid Android BETA7
-Slimkat
-AOKP kitkat
My current rom in use: 14.3.A.0.757 (NUT). I start the process by flashing 14.1.G.1.534 (NUT) then adding root (Bin4ry) and dual recovery (NUT) before going to AOSP roms.
Model number - C6903
Sim card - Tmobile pre-pay.
Quote from a Thread in XDA:
01. if u are coming from stock to AOSP then Downgrade to 4.2 .534 FW having Root and a Recovery ( but i think if u downgraded to 4.3 .290 FW then also it will do the trick )
02. Follow the instruction in OP with the recommended instructions - "After 5th point in Recovery go to mounts and storage and then Format boot, format system, format catche, format data, format everything u see.. Except SDcard1 (ofc).. And then move to 6th point."
If u flash .757 before coming to PA or any other AOSP ROM's then u might have trouble
As u have already done Step 01 then do a Clean reflash again with step 02.. hopefully it will solve ur problems

Flashing from .757 gave me a bootloop. There are no more links to .290. Hmm...

[SOLVED] Z1 brand new with .136 (4.3) Can I downgrade to .518 (4.2.2) stock?

My phone brand new came with firm .136 (4.3) so I can't root. Is there any problem if i downgrade to .518 (4.2.2) to root and install dual recovery? Would I brick the device or lose IMEI?
Well I just downgraded it and works perfect, I didin't lose IMEI, my phone is a C6906 branded Telcel MX

You are mostly right
You need a to be rooted, I suggest you use the 23.0.A.2.93 firmware to do this (4.4.4 - kitkat)
Have a custom recovery (click links to go to the posts)
Then flash a pre-rooted lollipop firmware
Sadly in lollipop they fixed the SuperSU Survival mode so the only way to get root is to flash a pre-rooted firmware

You will loose root if you update through OTA or through computer
You will keep root if you flash a pre-rooted firmware after gaining root on KK

Stock recovery lost!

Hi all, as the title I lost my Xperia Z1 stock recovery!
I had 4.4 with 14.3.A.0.757 firmware rooted and dualrecovery, and I updated to 5.0.1 Lollipop with PcCompanion. Then my Z1 became pretty slow so I wanted to flash this ROM http://forum.xda-developers.com/xperia-z1/development/5-0-rockz1lv1-1-deodex-advanced-mods-t3090064 on my phone, but I recognized I had not any recovery installed! So i flashed the 14.5.A.0.242 Lollipop firmware thinking I'll get back a recovery, but still don't!
How can I fix this?
Thanks

From taking what you have wrote, when you were on 4.4 kitkat you rooted your phone and put dual recovery on, your mistake was to upgrade to lollipop using the PC companion instead of finding a pre-rooted lolliop on these forums, hence the reason you lost recovery, the only way to get it back would be to go back to kit kat and then root your phone put dual recovery on flash the firmware you want from recovery.

Xperia Z1 Lollipop root

'Ello! I wanted to ask, is there a way to root the Xperia Z1 C6903 Lollipop 5.1.1 without having to downgrade it to KitKat? Or is there a way for me to downgrade and then upgrade back to 5.1.1 without loosing the root?
Thanks for the replies in advance.
Tip
Hi. There's a specific root tool for easy rooting called rootkitXperia, you can check here:
http://forum.xda-developers.com/crossdevice-dev/sony/root-how-to-root-5-0-lollipop-t3212108
But it supports only 14.5.A.0.270 and 14.3.B.0.310 (*Japanese model) firmwares. Flash one of these firmwares, root with this tool, install XZDualRecovery. then download .368 firmware pre-rooted version. Then flash pre-rooted firmware zip using twrp/cwm, it's your choise. You can choose wipe memory or not to wipe. Up to you.
Hope it helps

You can downgrade to KK 4.4.4, root it, install custom recovery, and use a pre-rooted 5.1.1 firmware to go back to 5.1.1. Or downgrade to LP 5.0.2, root it, install custom recovery, and use a pre-rooted 5.1.1 firmware to go back to 5.1.1
