need help with Rom flashing - Xperia Z2 Q&A, Help & Troubleshooting

hello all.
all the info out there is really confuse me.
some one please give me a valid links to here.
please correct me if im wrong somewhere in my understanding:
i own xperia Z2. my version is 5.1.1 stock.
the sound is crazy low ( after i put the max db at setting-sound...), so i searched what can i do about it, i've found there is a mod that fix this. as i understand, for that mod i should have recovery and rooted device, so i thought to myself "hey, if im gonna do root and install a recovery ill also will flash a nice rom"...
so i tried to follow some guides here but they are realy confused me.
at the links it says the root won't work for any device...
also it says it is gonna work for lockboot or something...
more over there is many methods and i dont know what is the simplest one.
there is more info that realy confused me and i want to be 100% sure im doing the correct steps...
I know i need to root and install a recovery, then i i need to pick some rom and flash it ( right?)
so please give me a links to here for what i need to flash a rom for my sony xperia z2 device ( v 5.1.1 stock).
ty for helping.

1.
The way i'd root my device on a locked bootloader is
- download flashtool and a older Firmware FTF
- FLASH the older firmware to my device and on the older firmware use a root tool to root my device
- I can now use root access to install recovery (XZdualrecovery)
- Download PRFcreator and a newer FTF with a superSU flashable zip
- Use prfcreator to make a flashable zip out of the new FW( include kernel and and all )
- copy it to device and flash it and be sure to wipe caches and data per big flash (e.g heavy FW changes)
- also google around for some things and make sure it all matches your device
(FTFs and xz recovery)
Also search for TA backup it may be useful for before you unlock your bootloader if you do
2/1. Use xda search tools to search Z2 section for root tool scripts
2. FTFs can be found in general section
3. You may want to add xz recovery to your upgrade flashable zip
4. Feel free to ask any aditional questions if you need more direction or detail
5. Unlocking your bootloader voids your warrenty (and wipes TA) if you restore your TA sony cant tell if you have unlocked your bootloader or not
(it also relocks your BL upon restoreing so be on a stock kernel)

what is FTF? is it the android version i have?
why i need an older one? i cant flash with 5.1.1?
about the steps:

is that root guide good for me?
http://www.xperiablog.net/2014/06/15/root-your-xperia-z2-with-locked-bootloader-guide/
after that i will use the next steps:

am i good to go?
what if i want diferent rom after i will flash this one?

FTF
I dont know its definition but its a full Firmware with included partitions so its essentially a factory firmware package
Kindof
Ita FW version and android verson
- Android rootkits use security exploits which google or sony may patch respectively
Rootkits dont work with newer FWs you will have to try 4.4.2 or the 55FWs
That guide looks good
After flashing if be sure to download a Newer FTF that matches your ROM version and be sure you flash only kernel
(exclude all) (some roms may not include a kernel)
To flash a rom after that one you can reboot into recovery and flash any stock based rom (and stock kernel to match Fw Version if it changes heavily)

Rootkits dont work with newer FWs you will have to try 4.4.2 or the 55FWs

what do u mean by that? i wont be able to use v5+ roms?
is there any rom's based on version 5+?
btw-what if i do something wrong, can i brick my device?
if i would, can i revert it and get it to life again?

55fws i ment the last numbers of a build number
The bugs that rootkits exploit are mostly fixed on newer Firmware versions (fw for short)
You need to downgrade to 55 or 402 fw to use some of the rootkits

i following those steps:
Flash official Sony's 4.4.2 17.1.2.A.0.314 with flashtool (http://forum.xda-developers.com/show....php?t=2162907)
Root using any method
Install NUT dual recovery (http://forum.xda-developers.com/show....php?t=2261606) or the recovery of your choice.
Reboot in recovery, Wipe Data, Cache and Dalvik Cache.
Flash the rom.
Follow AROMA Installer.
so i went to do step 1:
but there- it is written:
With this release, before unlocking first time, root your device
so? i need to do step2 first, then step1?

That comment is about unlocking you bootloader. So no step 1 then step 2.

Need Little Help

Hey guys,I own optimus one and I m used to rooting and stuff but my brother owns xperia mini pro so I need to install cyanogenmod (9 or10) whichever is stable.I had gone through various guides and stickies yet I want to be dead sure that I don't mess up my brothers handset. Its kinda new coz bootloader needs to be unlocked and also kernel image needed to be flashed separately unlike in optimus one.
Now I want help of you guys in the following manner like:-
1. My brothers mini pro is on ICS 4.1.B.0.587 and the rooting tutorial provided here for the said firmware
http://talk.sonymobile.com/thread/41119?start=0&tstart=0 is not clear to me coz it says that first I need to install some kernel [only mini mentioned here] then next I need to flash another kernel according to firmware. Can someone explain what is being done in this and why rooting is so complicated in this.
2. Certain ROM's say that you need to flash kernel first using flashtool
My query is that all ROM's that I flashed till now on optimus one included kernel and I only needed to flash ROM zip through cwm.. So do I need to flash kernel everytime I flash ROM!! and isn't there flashable zip for kernel too!!
3. FXP ROM's do not contain things like what's working and what's not, it only has issue tracker so it become difficult for new comer to know the bugs in ROM. Can anyone tell me the least bugs cm9 & cm10 ROM and what are the bugs present.
4. Lastly, should I proceed like this!!
i. Root device (though method isn't clear to me)
ii. unlock bootloader
iii. install cwm (I guess I can do this using flashtool)
iv. backup current ROM along with kernel (for future use,I know its optional)
v. flash kernel using flashtool
vi. flash ROM through cwm.
I m a quick learner and I just need some guidance on this new device (double checking coz its my bro's device) . Looking forward for support. Thanks

You needn't root first if you want to unlock bl, just unlock bl and flash a custom kernel (in most custom kernels cwm is included).
Backup your rom and install the rom...
hmmm....
1. Unlock Bootloader........
2. Flash Custom Kernel (all custom kernel is per-rooted and have CWM).......
3. Boot into CWM and Flash CM9 or CM10 (factory format/wipe dalvik/cache).....
4. Boot into Fastboot And Flash FXP kernel for CM9 or CM10.....
xperia phones aren't like sammy, lg or htc where recovery is a separate partition from kernel. in fact, by default xperia phones doesn't even have "stock recovery" like on other phone. by that we integrate cwm in kernel ramdisk.
and to answer the question:
1- flash custom kernel mean't for your phone only, never ever flash kernel intended for other phone. and its done via fastboot and should be flashed before flashing rom.
2- like i said u can't compare xperia phone with other phone like sammy etc, its different. kernel must be flash via fastboot.
3- for cm10, bugs that i notice is slow accelerator, but fixable with some text editing, and non working front camera for lww and minipro.
4- should be like this, according to order:
- unlock bootloader.
- flash kernel via fastboot.
- boot into cwm.
- backup rom if u want.
- wipe data, cache and dalvik cache. don't wipe system partition or u will get error when flashing rom later.
- flash rom, and gapps if its cm/aokp/pa rom.
- profit :good:
thank you guys.... this made me clear...
one last thing :- which kernel should I flash on stock 4.1.B.0.587 which is pre rooted and have cwm after unlocking bootloader.I mean the one compatible with above firmware and also do I need to do anything with baseband or will it be compatible. After this m ready to enter the custom xperia world
Remember to backup your stock rom before unlocking the bootloader as everything will be wiped clear.

No, i just meant that backup up your contacts, messages, apps (can be done through astro file manager) etc, before unlocking your bootloader because unlocking will wipe your data.

[Q] Custom Rom's

I did a search but did not exactly what I wanted.
Have a few questions in mind:
1.Can I Flash any custom Rom with my stock kernel?
2.Will doing the above cause any problems?(brick,bootloops,buggy rom)
3.Also unlocking the bootloader(is it necessary?Please a Noob here)via the official method(sk17i)I heard we would loose access to certain company features(track.id etc)would I loose access to official update of firmware from them?
4.Most of the Rom's featured here have not specified which kernel to be used with them could anyone suggest one which can handle most Rom's?

Please read the sticked threads, everything should be explained there
1. Yes, custom roms for locked bootloader
2. It can cause bricks or bootloops, roms where something's not working can be buggy
3. Unlocking the bootloader is necessary for nearly all custom roms like Cyanogenmod, AOKP, etc. You will loose your DRM (who needs them?) and track id won't work, but if you download the latest version it should work! You can't update via PC Companion, but you can flash official updates using flashtool :good:
4. All the kernels like Rage Kernel, kernel panic, x kernel, if you look in the kernel thread there should be explained for which software version they are...
That's it, but should be explained in the sticked thread, too

But if done properly they would run properly right? Without Bricking the device? Also should I be in ICS(stock) to install any ICS Roms(custom)? Or does the requirements for each Rom different?

Yes if u do it properly as instructed there should be no problem..U dont need to be in ICS to flash ICS custom roms. Just read the instruction properly in the rom threads

A bit too late. How to fix the loop? Should I use flashtool to flash the stock rom?:crying:
Or should I use the Sony PC companion to "repair it"
(Note I'm in stock Kernal With root, So will doing it via Sony PC cause more problems?Also since I have root will I be able to use the official updates and Repair options?)

i would suggest u nt to use Sony PC companion after rooting, unlocking BL as FOTA updates may brick ur device
(when u unlock BL its quoted there that not to do FOTA update after unlocking BL)
I dont know it brick device or nt bt why take risk?
Did u make a cwm backup??? If yes just restore it or flash the official ftf using flashtool....
I think I may have BRICKED it!!....stuck at SE logo at start-up cant enter CM recovery!!....I did make a backup in the SD card but since I could not enter recovery no use. I tried to flash the official firmware via PC(flashtool) but it says USB debugging is disabled!
Have I officially BRICKED my device? is there any way to get back to the good old GB and stock Rom?:crying::crying::crying:
Use Flashtool, Flash the Stock FTF and all should be come good again
Or Use SEUS/PCC and try The Repair Option

[Q] Totally confused.

Hi guys I am sorry I've been reading a gazillion articles today and I simply got very confused with all this things. All I want to do is install CWM and then install CM10 or 10.1 on my ST15i. Bootloader is already unlocked with official Sony guide and Bootloader code I didn't know if it had to be done before root but I did it anyway. I tried many MANY options including Flashtool, RecoverX and some other things. I do have everything setup but I think I am having problem with my baseband. It's 4.0.2.A.0.84 and I don't see 84 anywhere. Can you please just at list point me on where I can find 84 root instructions or may be downgrade to other baseband cause I do see some older baseband rooting instructions in here.
Thank you very much. I really can use some help.

though u don't need anything else if u have an unlocked bootloader,
download the rom, and gapps
extract to pc and copy to sd
flash boot.img in fastboot
boot into cwm(u'll have after you flash kernel)
flash zip from sd card, romm and gapps.
Okay this is what I call "From last dying breath" I found this life saving post. I was be able to downgrade to 42 using flashtool 0.9.10.1, then root device with same tool, then use RecoverX to install CWM and ...well then I did backup of my current system and that's it.
Thank you guys for bringing all this knowlege I guess if you search long and hard enough you'll do it cause it's out there. In my case it was just that I didn't see that baseband and android version have nothing to do with each other ...like 4.x.x should be ICS right ? ,,,,no it still showing Android 2.3.x
Anyhow thanks a lot !

Sorry, my bad it's just late totally fried in here.
Just flash any pre rooted kernel with cwm and then no need to root it again. Anyways if u want to root.84, then follow the same method that is for .62 and u might be successful. Please let me know if u cud do it
Press THANKS if I helped,
Best Regards,
AJ
the .84 baseband is GB based ...you will need .587 ICS baseband(Baseband 77) for CM 9.1,10,10.1
Upgrade to ICS .587 (there are bunch of ftf here and there )
then follow this instructions
http://wiki.cyanogenmod.org/w/Install_CM_for_smultron
Get the release wither from CM or from FXP ..Both are same usually ...FXP is weekly ...
Root is not needed to flash ROMs with unlock Bootloader ..The fastboot kernel has recovery and is prerooted usually
The problem is .431 and .587 are on ICS bootloaders (Baseband 77)\
and 0.62 and 0.84 is on GB bootloader ..(Baseband 84)
.84 may be newer firmware but it is still GB ..
Upgrade to ICS for CM

wt19a kernal rom compatibility

hi.
i have a "lww". im root. my model is wt19a 4.0.4 build 4.1.B.0.431 kernel [email protected] # 1.
can i flash any kernal for my phone? if no, does it have to be compatible by build or model?
First of all to install custom kernel You need to unlock bootloader. Not every phone can be unlocked, cause it depends if Your phone's bootloader unlock status is yes or no. You can check this in service menu (in dialer tap *#*#7378423#*#* [ *#*#SERVICE#*#* ] ) and go to Service Info and Configuration. There should be rooting status.
It's also good to make .FTF files from Your ROM to use them in flashtool BEFORE any modifications. Just in case http://forum.xda-developers.com/showthread.php?t=2075736

Thanks for the reply.
my bootloader says yes. now i thought the whole thing witht the bootloader was for rooting. like i mentioned before i am rooted. i have already made a backup of my stock rom if thats what you mean by making my own .ftf file. dude where is the thank you button?
Nope, rooting Your device will give You access to system partition, but it doesn't allow to change kernels.
Backup in .zip is fine, but I suggest to make a .ftf. It will help You to "unbrick" Your phone if something bad happen (cause if it's problem with ROM U have to flash any working ROM anyway, but if U unlock Your bootloader SUS and PC Companion won't work, so the only solution is to flash it using flashtool). Also .ftf will allow You to revert software to stock one, with branding, customization etc. (if U would like to use warranty for any purpose stock ROM and branding are necessary).
So if bootloader unlock status is yes - then U are able to unlock Your bootloader and install any custom kernel. Check this thread, it will help You with everything. http://forum.xda-developers.com/showthread.php?t=2148684

i found that thread last night thats why i posted this question.
my boot loader says yes. i also flashed cwm using recoverx.
just to be sure. with my phone software the i mentioned above ^^. using lets say flashtool i can flash any kernal rom combination even if it .587, or for lets say or the wt19i?
thanks again for the help.
No, not every combination will work And flashtool is used to repair phone, not to flash custom ROMs. There are some ROMs working on stock kernel (which U have now) - mainly based on stock .431 or .587 software. U can flash them using recovery (which U have now). To be honest I don't know what are the differences between wt19i and wt19a. But as a experiment (lol) I flashed baseband from SK17a into my SK17i and everything was ok. That's why I told U to create a ftf package, which will allow U to flash stock ROM if something went wrong.
So, for now:
If U would like install any ICS ROM (based on original Sony .431 or .587 compilation - You can try it right away.
If U would like to flash CyanogenMod ROMs (CM7.2 [android 2.x GingerBread], CM9 [android 4.0.x IceCreamSandwich], CM10 [android 4.1 JellyBean], CM10.1 [android 4.2 JellyBean], CM10.2 [android 4.3 JellyBean] ) and other based on it, U will have to unlock bootloader at the first place and then flash kernel suitable for Your device (LWW is coded as coconut) and then flash ROM.

im sorry i asked so much. as your aware im a noob. till now i only rooted/flashed a galaxy 5 (not s5). it was so easy.
i assume im going to use cwm to flash the kernel, am i wrong?
if not a tutorial link will be fine and ive got all the points. and this is one hard phone to customize. but i wanted the 1.ghz processor.
thank you like in a big way man.
CWM is used to backup Your ROM and install custom ROMs. To flash kernel U will have to use fastboot mode, and it has nothing in common with CWM. Check this thread, 2nd post: http://forum.xda-developers.com/showthread.php?t=1730874

Ive been trying to figure out how to go about rooting my tablet but since I am new at this stuff I just want to make sure I dont **** up
My questions are:
1. My tablet is 5.0.2 atm, as far as I know I have to downgrade to be able to root?
2. If I need to downgrade I believe I need a FTF file, I have a LTE version which is bought in sweden. Do I need a specifik FTF file for my country or can I use http://forum.xda-developers.com/showthread.php?t=2741233to downgrade my tablet?
3. Can i still use this guide http://forum.xda-developers.com/showthread.php?t=2792056 to root my device after I downgraded the firmware or is it outdated? If its outdated is there any updated guide I can use?
Any help is appreciated!

1. There is this: http://forum.xda-developers.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461. But it ain´t give proper root and there is also some security concerns with it but your decision.
2. Yes. You need FTF file which is 4.4.2 firmware for you device. Latest rootable is 17.1.2.A.0.314. Here is download link for SGP 521 if you want. https://mega.co.nz/#!cN5ykLrL!0w38j4lWIHFm1rZdwexScG9Cpz2BghrSZPpLRkyTcL8 . However your link should work also. If you only use it for rooting it don´t have to be for your region.
3. Your link would work for rooting properly. However there is other methods too.
4. After you achieved root just install custom recovery for you device and flash latest prerooted firmware for your device with it and you are good.

Alright mate would this work for me as I took it that I need to unlock the bootloader to install a custom recovery?

There is no need to unlock bootloader if you just want to root your device. Bootloader unlocking is needed if you want to try custom kernels or roms that use custom kernels. And yes this work for your device also.

OK so with a locked bootloader I can downgrade to 4.4.2 for my region model root using kingroot..? Then install a custom recovery without having an unlocked bootloader then flash Pre rooted ftf lollipop ROM build. Is the updated kernel and firmware in the Pre rooted stock ROMs? Thanks.

Yes you can downgrade to 4.4.2 firmware with locked bootloader. After that you don´t need kingroot to root your device because @[NUT]´s dualrecovery pc installer can root your device before it install custom recovery. After that you can flash prerooted firmware (= .zip file) with custom recovery. Usually prerooted stock roms has whole firmware including kernel. Their also include SuperSu and custom recovery. And there is no need to unlock your bootloader in any step for this unless you want to do that.
OK so I flashed a ftf file from this thread http://forum.xda-developers.com/showthread.php?t=3061431 I don't think its right as its for HK etc. A 4.4.2 ftf. 17.1.a.2.402 HK/sa/as/kw.
I was on 23.1.A.1.28 in the UK as O2 UK being the 4g network. But according to that thread the 23.1.a.1.28 I was on is generic HK so I'm confused. How can I get back to my original then? Thanks

I have tried both ways. Including ta partition and excluding it. Both works just fine for me.

OK thanks I did it without the ta partition like suggested but wasn't sure if it was 100% correct. Should all be fine though. I'm currently now rooted and all fine but what I want to do is have a Pre rooted flashable zip of my ftf I've made so it is my actual stock ROM I'm running. I've looked into the prfcreator but don't wanna do it and run the risk of bricking my z2 tab. Have you used prfcreator? I guess all I need is my ftf file to use. The most update supersu zip I want. And then I need to somehow have the xzdualrecovery.zip but not sure if that's all I need or if I need the current Sony signed kernel or what. Thanks

Must admit reading up more looks pretty straight forward as I just use NUTz xzdualrecovery flashable zip as the recovery zip. I'm just unsure on whether I would need to check kernel otakernel modem and ltalabel for our device. Thanks

Depending what you want but if you include everything else but signing you end up to fully functional prerooted firmware.

Sorry mate if I use my ftf and super su.zip and xzdualrecovery.flashable.zip then add all checks do I also have to get it signed? Or I can do all checks and not need signing and it will be fine...? Sorry mate first time and all just trying to work out different things thank you.

No need to be sorry. You don't need to sign your zip because TWRP can handle unsigned zip files just fine. There is nothing wrong to sign your zip file but some times it can cause problems. Your choice.
