Hi all, im a newbie here, i bought my Xperia PRO a month ago, and rooted it on Android 4, using a great tutorial in this forum and thanks to other members i got it right and rooted it in my 4 first days of use. But, i now want to upgrade to a Custom ROM and use a custom kernel , to get my phone to a new generation.
And my question now is, how can i flash a Custom ROM (i was thinking of CM9 stable when it comes out), and flash a custom Kernel with it (i was thinking of Ultima V1.4) and then keep my old applications, or most of them.
I have CWM Recovery 5.5.0.4 installed using X-Parts , and also Titanium Backup Pro . My Bootloader is still locked and i have flashtool and all drivers for my phone installed on my PC.
I would be very thankful to anyone that is able to help me do all these, or if needed, recommend me a better Custom ROM and Kernel, and then explain how i can O/C my phone too, and keep if possible most of my apps.
Also, please tell me if i have to install anything else, or if im missing anything.
Thanks in advance.
Hi mate,
First of all, I take it that you know that you have to unlock your boot loader to install custom kernels and some custom rom's. Like CM9 and 10.
ROM Install Instructions
There are normally instructions that are in the first or second post that explain how to install. If there aren't any, I've copied the instructions from maxio1998, so all credits go to him:
1. Download .zip file and place it on SD card
2. Download and flash kernel you like (or not, if you have locked bootloader)
3. Download WiFi Modules of chosen kernel and place them on sdcard
4. Go to CWM Recovery.
5. Wipe everything! (This means everything but the SD card, or you'll use all you files)
6. Flash zip with ROM
7. Flash zip with WiFi modules
8. In CWM go to "Advance" and fix permissions.
9. Reboot and enjoy [~xDevilCharged~] and PentaPowerful~ Jelly Sandwich!

Kernel Install instructions
To keep it simple, heres a program that doomed151 made. It flashes the .img without having to use command prompt: http://forum.xda-developers.com/showthread.php?t=1551073
Right, onto keeping your apps. As you need to wipe everything to install a new ROM, you can't keep your apps without backing them up. Titanium backup is the best option, and you've bought it, even better :victory: The wipe will not delete the backups from the SD Card so just place them somewhere on there.
You can use any overclocking app from the market as long as you let it use superuser or supersu. Don't recommend passing 1.3, it gets very hot and the cpu will burn out quicker. (Yeah, I know i've overclocked mine to 1.5, but it gets very hot and runs out of battery quickly)
As you've already got CWM installed, you'd be better doing a full nandroid backup, just in case you decide to revert back to stock, you have all your apps installed
Unfortunately, I'm using the arc, so I can't recommend any kernels or ROM's to you. Sorry.
If I've missed anything you need to know, just let me know. I'll try to help
Awesome! Thank you very much my friend, very detailed and nice guide. I'll wait for CM9 stable to be released for my phone an then ill try it out.
Thanks again.
Also, I've searched enough, to believe that cyanogen mods, are the best and most recommended custom ROMs, about the kernel, I aint so sure but ill see what other user's might say.

If i remember right, CM9.1 (stable) has not yet been released for iyokan (MK16i). So that means i have to wait. Also, i can flash a ROM and use a kernel other than the ROM's default one, right? (i want CM9.1 with Ultima V1.4 Kernel)
And one more thing, i have moved all apps to the SD, what will happen to the files there? Will they remain?

I think that you have to use the cm kernel (fxp kernel). Could be wrong though, not really looked into it.
Any apps that you have installed on your phone will be deleted. You have to back them up and then restore them. It doesn't matter where they are installed

so, how can i be sure if it is possible to flash CM9 with Ultima Kernel?
Also, do i have to do anything with google apps? And flash another baseband or something like it?
And last but not least, i have installed CWM using X-Parts, will this affect anything?

Sorry for late reply, just look up the thread again.
Best thing you could do is ask a question the Ultima Kernel thread and hope you get a response. But I think that it will be for stock only, (I think they need different things in them....) but im not a dev, I don't have the patience..... :laugh:
You might have to flash google apps. Just use CWM in the custom kernel you choose. They will be a link in the bottom of the first post to the google apps download.
No need to flash another baseband or owt like that. When you flash the full zip of CM9 in CWM it will add and edit everything you need.
CWM from X-Parts will not have any effect on anything after you flash a different kernel. It will disappear like it was never there.
Hope I'm able to help again Need anything else, just post again, I will pick it up
Good work Jon565G
Not just good, excellent work!
I did it, and flahsed the kernel and all that stuff, now i reinstalled all my apps , and O/Ced at 1.2Ghz , and everything is nice.
But, working on android stuff, makes you want more and more, and as you learn better, that makes you want even more, and now i want to mod another phone.!
I've learned a lot from your help and the help of other members of this forum, and i think i am now ready to "mod" more phone, just for fun.
I already managed to flash an x10 mini with miniCM7 and flash a nAa Kernel, and also flash another x10 mini pro with miniCM7, and probably today ill mod another friend's x10 mini. And later two x8.
Learning, is great, thank you all.
EDIT: I also found out that everything you need is Flashtool, its the best tool out there, it flashes, it installs Busybox, recoveries, it unlocks bootloaders, it roots, it flashes kernels, everything. .Ok you might also need s1tool to check about the semc lock and if you unlocked the bootloader.

I know, I'm the same. I'll want to go and buy about 10 different android devices just to have a play around and mod them. It's always nice to play around with 2 android devices (Please come back in stock Nexus 7 )
Anyway... I'm just glad that I was able to help to introduce you to the world of android modding.
Have fun, that's what it's all about :victory:
(I had to use multiple programs, my bootloader could only be unlocked my test point. Was locked to T-Mobile. Best use of flashtool is when you've bricked it and need to get it back to stock )
I hope you get back your Nexus 7 then
Yeah, i unlocked my Bootloader using testpoint method too, so i wouldnt get any bricks with FOTA updates. And, i also used to be into such electronic stuff.
And, you didnt just introduced me into Android Modding World, you made me a fanatic Android Modder
Anyway, thank you once more, and yeah, thats the point, the fun about all these stuff

well, from what I've read, in ur Xperia u can simply find out the bootloader status by dialing *#*#7378423#*#* service info> configuration
rooting status
bootloader unlock allow:Yes(if locked)
bootloader unlock:yes(if unlocked)
m havin locked bootloader, so do reply with ur status and confirm this to me and evryone else

I am not sure, but i believe, that either you have locked or unlocked bootlader, it will always say "Bootloader Unlock Allowed: Yes , or No if its not allowed).
I aint sure, because in CM9.1 i dial it, and i cant get to the Service Settings, so i cannot be sure.
And, as i've found out, you can be sure if you have locked or unlocked bootloader, by running S1tool, and pressing "IDENTIFY" , which will tell you to connect your phone in flashmode (phone off, connect USB while pressing back) , and it will give something like "loader version xXXXXXX" , where the capital X , are numbers, and the small x, is either "R" or "r". If it is a small "r" , that means its unlocked, if its a capital "R" its locked.
If you want to unlock your bootloader in the Xperia Pro, just tell me , and im sure i'll help you out, with a detailed tutorial, without having any problems.
Hope i helped.

Hi,
I have Arc S , Locked BL, still under warranty.
I have tried multiple ICS Roms, but all are very laggy,
I'm now on Stock GB and it's really smooth, but it's from 2011, and we are in 2013 !!!
I wanted to unlock BL, and install a custom kernel and rom (ICS , Jelly bean, ... ) . will these improve performance ? or should i stay on GB?
And I will use testpoint method in order to relock it back completely if i need warranty later on. is that right ?
Thanks guy
Yes certainly .
Not that I know of.

I Believe if you are advance it doesn's worth an no problem
it's awesome if you like to test ROMs... makes the process way faster as you don't have to go to flashmode first and flash stock rom and then root it and then install xparts etc etc etc...
with unlocked boot you just install kernel (), wipe stuff in CWM and install ROM and that's it.
Gives you access to try out kernels which some are better than others but all of them are better than stock...
and gives you access to try out JB roms and kernels... although for this keep in mind that HDMI does not work on JB roms because developers need Sony to release proper jb drivers.
Good luck!
one more good thing is that you can overclock (Done at your own risk), I bought a new phone and unlocked BL within hours of having it
Just remember that warranty/dmr and bravia is lost
Totally worth it man. You can adapt your phone to the kind of person you are, the kind of user you are, by customizing it 100%. And you don't loose anything though, if you want your HDMI and 720p @ 30fps and bravia, etc, back again, just flash any ICS rom or GB based, and voilà! Unlock your bootloader, Unleash your phone.
Yes it is worth it.
You may get a much better experience than you are currently getting.
Allows almost full customization the way you want it.
If not it is very easy to go back to stock.
Flashing re-flashing ROMs may look difficult at first glance, but once you do it by following guides it is very easy and so addicting that you may end up flashing something new everyday !
Thank you all for you encouragement,
I unlocked it since thursday, and I am enjoying full stuff of my phone,
I have been trying roms on locked BL since january, but all are slow.
Now with custom kernels, the same roms run much faster and smoother, and battery is longer .
Thank you guys for help

Hey!
I've had my Xperia S a year and a bit and i've flashed various roms with flashtools to get it rooted. Never tinkered manually and always used official roms just prerooted.
With JB I can't seem to find a prerooted JB rom that I can flash with flashtool. Could someone point me in the right direction or recommend me a rom here that will do that job?
I don't really want to change the Sony JB much, just have it rooted again so I can use titanium backup and restore aswell as remove a lot of the apps that come preinstalled and I can't get rid of, like wisepilot, foursquare, etc. I want things to be my choice
Thanks for your help

If so, it's easy.

Ah, Plan B... You're probably not going to like it.
I believe a locked bootloader XPERIA LT26i can only be unlock in ICS and then use DooMLoRDs(or another) pre-rooted official Sony ROM to get to JB using CWM recovery.
I don't have a locked bootloader, so I'm just following a wild path that ended at the following URL.
http://forum.xda-developers.com/showthread.php?p=39498268
Have a look at it and do nothing for a while.
You may get better informed information than I'm providing in the next few posts, which could lead to a more effective path to root access on JB.
Good luck with that.
[Update]
P.S.
I see in the thread I referred you to that in the latest few posts attempts are being made to gain root access on JB. So fingers crossed if no other options came up.

Thanks for your help I appreciate your time as i'm having a crappy time with the phone haha.
Before I took at look at your link I flashed my phone a few times and remembered how I had it rooted in ICS. If I can get it rooted this way again, (I have to flash to GB then run a few .bat's and then ICS and another .bat). Is this the same as what you say? I will end up with rooted ICS then can flash the pre rooted Sony JB rom?

That's my understanding at this time, BUT...
Have a look at the last few post of the thread I refereed you to, as they're attempting to gain root access on JB, which if successful, may prove a faster route. Depend on time taken to get a successful root via JB though.
Ah its all getting complicated.
Would it be easier if I just unlocked my bootloader?

Complicated, to many options???? :laugh:
To be honest, I'd not unlock the bootloader at this time.
There is some indication that you'll lose your DRM keys in the TA partition and this is mooted to impact Bravia Engine and maybe something else I think.
There is ways to backup the partition and then restore it at a later date, but to me it sounds a little like it could end in tears.
I unlocked my bootloader ages ago as that's how I roll, and I tend to tinker and install anything that's bright and shiny... which mostly means an unlocked boot loader is required.
If you can just root ICS .55 it'll be quicker than the option I took of rooting .45 and then upgrading the kernel of 55 to retain root.
It all depends on how involved you get with different Kernels and ROMs as to whether you unlock the bootloader.
To be honest, to get a good JB experience, you just need a JB ROM, rooted, bloatware removed, something like SetCPU from Google Play Store to manage battery usage with screen-off profiles and etc and that's basically it. Stamina mode, if installed, is the laypersons option to battery management.
A good Kernel like 'what' @DooMLoRD provides is always going to improve the over-all experience with added features and etc which may be the tipping point to unlock the boot loader, but I'd wait until the need was there.
Sony is to release a new firmware 6.2.B.0.211 soon which may be worth waiting with a locked bootloader for.
You can always disable any unwanted applications in the app manager to better resources.
JB is probably(I have no idea really) the end of the line for official Sony firmware on the XPERIA S (snapdragon S3) and so to go beyond JB 4.1.2 at a later date will more than likely require an unloaded bootloader. That said, you never know.
Just thought I'd throw in a few more options for you.
Thanks for your help
I think I have got it. I rooted ICS and then applied the update.zip. JB is running and Titanium backup tells me i'm rooted! Yeehaw!
So just need to remove bloatware.. Have you got any tips regarding this? I remember trying ti on ICS but broke my phone in the process, I guess I uninstalled things that were needed or something

just one doubt, (sorry, i read the whole post.)
got the idea to root JB, but is it necessary to unlock boot loader for this to work,
because at some point we have to flash the pre-rooted kernel through CWM right? So for that the boot loader
should be unlocked also..????

Oh right. I have CWM working though, needed it for the rooted JB. I guess I can live with the apps I don't need.. unless I can still get rid of them. Titanium backup lets me uninstall such things but I guess this is dangerous?

Dude, you totally rock.
You are about to install pre-rooted, JB. Do you have your install buddy? :silly:
So, when you get to the following and can tick all the boxes, you're ready to install a pre-rooted JB ROM
[ requirements ]
BOTH LOCKED & UNLOCKED bootloader!
Previously on stock .45/.50/.55 ICS ROM or roms based on that [since baseband of the official JB ROM is same as ICS ] supplied ROM
Any existing recovery!
Then progress to the following URL and install JB ROM
[ROM] Official Sony JB 6.2.B.0.200 ROM Pre-Rooted CWM
You may lose root access directly after the install, but that can easily be restored by flashing DooMLoRDs SuperSU and Busybox zip from flash recovery after the ROM install.
Titanium backup is only dangerous in the wrong hands.
I'd start with apps like WisePilot(if you're not using it) and etc by doing a Titanium backup and then uninstall the app.
You can freeze an app too, as a first stage to later removal.
There are probably lists of safe to remove apps on an XPERIA S as the system apps are not much different to ICS 4.0.4
Just remember, don't get to busy removing system apps, as Sony firmware 6.2.B.0.211 is coming soon and you'll have to start all over again.

I got it all running... Is that rom meant to come with games like Block Breaker and Modern Combat? I can't seem to uninstall them, they don't appear in the titanium backup list.

That's true, it's a stub for the game download.
You can use a file manager such as "Root Explorer" or "ES File Manager" with root access enable (i.e r/w access to system partition)
I deleted(cut and paste to /sdcard/appbackup/jb200/app folder) the apk, and it was in either of the following two folders.
/system/etc/product/applications/
/system/etc/customization/applications/
Titanium Backup is probably not looking further than /system/app
I can seem to access my mobile network when using a custom ROM: It always says no service.
If I go back to stock, then I can access it but the moment, I install a ROM, it is no longer available.
Background info:
I got a brand new Xperia Play a couple of months ago and successfully installed Pacman Rom on it.
I then recently switched to Racing XPLAY. I then wanted to try out some of the other ROMs and so installed them using the excellent CyanLabs tool.
At first everything worked fine. However, after a while, each time I would install a ROM, I would get stuck in a bootloop.
Eventually, it got so bad, I had to flash an FTF, using the ones in this thread.
Since doing that I can't access my mobile network on any custom rom. Additionally, I am unable to use Cyanlabs to install roms automatically, and have to do it manually.
I would appreciate any pointers. Thanks!
Not being on here long but I've done a lot of reading since I have.. From what I can understand there's two types of ROM's, CDMA and GSM, you might be custom installing the wrong type to your phone *(R800/800i need GSM, R800a/800x need CDMA), also from what I've read some may need extra modules installed to correctly run certain parts of hardware. Try another Stock rom for customising, (big list here) Also, loads of people here favour Flashtool to install Rom's, maybe trying that instead?
As I've seen mentioned lots of times on here... Read, re-read and read again, your probably missing something so simple that'll be stopping it working 100%
*I'm sure someone will correct me if I'm wrong.. Newbie and all that.

Thanks for your help. I live in the UK and have a R800i, so I have only being installing GSM roms.
I have also tried via, flashtool, but same problem.
It's weird, if I FTF back to stock, it works fine. It's just when I install a custom rom.
I've searched really hard, but haven't found anything that helps.
I really would appreciate help, as I don't want to be stuck on stock!

If you game a lot your best bet for good gaming performance is stock debloated. I have tried many a custom GSM roms here and as much as I appreciate and have the utmost respect for the devs here I always come back to stock debloated as it gives the best performance.
The FTF I am using is the generic UK one. Is that the correct one to use?
I tried going back to a backup I had made before all this started, but its the same problem (no mobile networks). Does this mean it is a kernel issue?
BASEBAND?
I did also face this issue when i flashed a ftf with incompatible basebands.
I had baseband 54 by default, then i flashed an ftf while baseband was unchecked in flash tool, and bang, cellular networks, data, etc were giving issues.
I would recommend 2 things, check if you have a sim locked phone, in which case you will need to sim unlock it
secondly, search the android development section for krisdee's Xperia NXT, which has a link to firmware 4.0.2.A.0.58(enhanced). flash it. I think it has baseband 64 which is good as per my experience. Then flash any ftf with baseband unchecked in flash tool.
Thanks,

Got this working!
You have to download and Flash R800i_4.0.A.2.368_World--stock firmware WORLD in this thread:

It works perfectly then!

Hi!
I want to revert to JB 4.3 from KK 4.4.2. Partly because of battery life, RAM use but also because I'm using an external SD card - which basically is pointless from 4.4. on as I've understood... Yes, I can store media files there, but I cannot move 3rd party apps from my internal storage (which I want to keep "clean"); e.g. I cannot move a Kindle book from the internal storage and on to the external SD card.
Also, I've noticed that when I take a picture it is stored on my SD card as I've chosen in the options, but if I edit it the edited version is saved on the internal storage... and uses precious space there. And the only program I can use to relocate it to where it belongs is FileCommander, which isn't the file manager of my choice, to put it that way...
The reason I chose this phone rather than i.e. an iPhone 32GB was, apart from it's (at least supposed to be ) waterproof, is (or rather was, at the moment) the option of using an external SD card to augment the somewhat abysmal storage capacity of 16 GB. With Google's new policy that only 1st party apps can write to it, the point of having an SD card becomes quite debatable...
So, basically - I want to go from Sony KitKat 4.4.2 back to Sony JellyBean 4.3 - nothing more.
And then, the questions I need to ask - and hopefully receive answers to. Perhaps people in the Nordic countries - and specifically Norway are best suited to help me.
1) I was thinking of simply using the approach in this video: http://www.youtube.com/watch?v=zNE3eZnlHIw
Which is basically using an official Sony 4.3 flash and use that and flashtool to overwrite 4.4.2 on the phone. ...or did I miss something?
I've noticed that I do not have any Developer options under my settings, but it seems that USB debugging is on by default.
a) Will this require that I unlock the bootloader (and perhaps void my warranty - living in Norway)? I can do so (unlock bootloader says "yes").
b) Should I root the device - do I need to back up the TA partition? Also because of potential warranty issues... I cannot understand why, as the phone had JB 4.3 when I got it anyway...
2) Is this 4.3 ftf usable for me, living in Norway? http://forum.xda-developers.com/showthread.php?t=2657610
I've noticed that some have expressed a little irritation since this ROM is in Chinese... Which I of course can't use. Is this usable anyway? Or are there any other more or less official ROMs I can download - I'd be happy enough even if from Sony itself?
I think that's all - at least for now. Hope some guru out there is able to help me.
You can use any ftf (Z1 compact firmware of course), but I don't recommend the one you linked as it's a chinese firmware. Check here for firmwares: http://forum.xda-developers.com/showthread.php?t=2631291
You don't need root or an unlocked bootloader to flash stock firmwares.
As for developer options, go to Settings => 'About phone' and press 7 times on 'Android Build'. This will unlock the Developer options in Settings.

OK, perhaps this is better then? I see that's older than the Chinese ROM....
http://forum.xda-developers.com/showthread.php?t=2633924
This and the Chinese ROM mentioned in my OP are the only I can think of "match" my phone, as the other two appear to be UK and Germany specific, respectively...? Remember, I was thinking of going from KitKat back to Jelly Bean...
That is from 14.3.A.0.757 to 14.2.A.1.142 (or maybe I have to settle for 14.2.A.1.114).
Also, if any one has good arguments for keeping KitKat or perhaps know of work-arounds for my main issues (file management and OS and app RAM usage), I'm all ears.
As I said you can use any firmware. The UK and german are not specific for that country, they just have a different customization. For example the UK version has the 4G icon and the option to enable national roaming. The pre-installed apps are also not the same.
I don't know any work-arounds as I've not experienced any problems since I upgraded to KitKat. There is a fix though for the SD card but it requires root.

OK, wasn't thinking of going there originally, but JUST IN CASE I want to try that... Could you give me a pointer as to the procedure? That would be most helpful.
EDIT: Is it about rooting "only" (will probably be challenging enough...), and then installing this one: "SDFix: KitKat Writable MicroSD" ?
(forum rules prevent me from using an external link it seems, sorry)
Yes, that's the fix I was talking about. I'm not using it because I didn't face any problems yet with KitKat's SD policy.
Sorry, but one thing remains somewhat unclear for me.
If I decide to stick to KitKat, is it enough if I root the phone (and keep the stock installed 757 OS) and then install the SD Card KitKat fix? Or do I also have to unlock the bootloader?
I'd be very happy if I don't have to do the latter, I must admit... I don't like the idea if I screw up totally while unlocking the bootloader and void my warranty and DRM rights, as it seems to me now that I've read a bit about this that unlocking the bootloader is what can really cause trouble... If I've understood everything correct.
Bootloader unlock is only required if you want to use custom kernels.

In other words, this should work just fine?

Yes, you can just do the rooting part. I recommend to upgrade to the latest KitKat firmware after rooting ( http://forum.xda-developers.com/showthread.php?t=2688933 )
