Develop Bugs

[Q] Question needed to be answered

Hey all!
I am quite new here so yeah.. At first i post a thread about some questions but still i don't understand some.
1: How do i unlock my bootloader without SE detecting it as a unlocked bootloader. Some say use SETooL/Omnius but i am still not sure about that. I don't want SE to detect my phone's bootloader as unlock. I know if it does my warranty is as good as dead.
2: Flash? What is flash? More importantly how do i flash roms onto my LT18i? I need a clear step by step instructions. What do i need to have before flashing? ADB Drivers? PC Companion? Is there a video that can teach me how to flash roms/kernels clearly? Give me an example on how to flash using a rom that can be flashed on Xperia Arc S.
These things might be hard to answer as it is in every noobs mind. So please help me understand, these things. How? What is needed? Example? I need answers. It is hard to search for answers as i am busy with my school and i am having Common Test (Sort of an important Test that is counted in my Exams). I am willing to learn more about this Android development thing.
Thanks,

1. Contact Jinx13
2. With recovery or FlashTool

But! But! I don't get it! How about on my Arc S?! Is a free method available without removing the DRM stated in your video? Mine says BootLoader Unlock Allowed: Yes. But if i use the paid method (SETool 2) will i need to like connect the testpoints or something. This is for my Xperia Arc S

Success! After some experiments I finally unlocked my bootloader and I flashed an ICS Rom!

You Can be on the latest firmware with root ....
Update OTA after Rooting ........
a) Your Boot loader should not be unlocked (Default setting by Sony Ericsson)
b) Root your phone which is running on .42 firmware using the latest Flashtools v 0.6.8
Note :
i.First install Flash tool.
ii.Connect the phone in Flash Mode
iii.Flash it with 4.0.2.A.0.42
iv.Turn on the phone when flashing complete
v.Connect the phone with usb debbuging enabled.
vi.Open the Flashtool
vii.Then press the lock icon on flashtool.
viii.Phone will automatically reeboot after done

how can i enter sony recovery ?

hey ..
i ask about how can i log in Recovery mode for Xperia Arc LT15i without flashing kernels.
I want to enter recovery of sony , want to keep sony logo and the ability also to enter recovery without pc.

Do you have you root? If do you can install clockworkmod/cwm which will get you into recovery mode there is a link to download in the dev section or go to market and download it is free.

uhm are you using the stock rom from sony?
because i'm pretty sure .62 cant be rooted with zergRush

Like the post above you can't directly root.62 with zergrush method.
If your bootloader is locked you can use flashtools to downgrade to .42 then get root with zergrush, then you can update over the air to .62 and still keep root.
If your bootloader is unlocked do not update over the air out you will brick your phone.
Look at the stickies you will find all the tools you need.

the Bootloader is opened and i uses a prerooted kernel and Windy Ser1es 30.5 rom.
when i try to use titanium back up, it said Root : can't access. so why ? i dnt know.
now, i want to do root manually, how i can do this ?
i want to keep my opened boot loader and keep sony logo with recovery, how can i do this also ?

Flash DooMKernel to get root and then flash the other kernel to keep the Sony logo.
But why do you want to keep that Sony logo?
DooMLoRD's bootlogo looks much better

thanks for your reply.
another 2 Qs :
-what's the difference bet. CM7.2 and CM9.0 and which is better ?
-which kernel is best to use ?

CM7.2 = Android 2.3.7
CM9 = Android 4.0.4
For CM ROMs the included kernels are the best
For gingerbread from Sony I'd say go for DooMKernel

[Q] Stuck on sony screen after x-parts CWM, while installing ultimate HD

So i have searched for simmilar threads but i didn't find what i was looking for.
I have xperia arc s 4.0.4. B.O. 587 and i rooted it. I also wanted to install ultimate hd mod and followed instructions. I placed custom rom files in sd card. Then installed x-parts CWM. Chose to reboot to CWM recovery. Did all the things jadar12354 wrote (reset to factory settings, wipe system folder, wipe batery data.) and i wanted to install ultimate hd, but it just wasn't there. i chose just to reboot. And gues what :crying: MY phone f*****g froze on sony screen.
I don't know if i have a unlocked bootloader all i know is i did this root thing
Seriously, i'm kind of a noob at this, i've been reading everything over 10 times to understand. Took me 4 hours just to root the damn phone.
What i tried is connecting arc s to pc via back button and go to flashtool and flashing the kernel or something. I've found guys who said to renew the rom but i don't know how to do this.
Please help i'm anxious that the phone is done for, can you please tell me how screwed am i?

Go to the sony web page and download Sony-update app. Than run app and choose your mobile model and reinstall stock Rom. That's the easiest way to back to original rom

Not if he want's to risk bricking is phone!! He said he is not sure if his bootloader is unlocked or not.If unlocked he needs to flash a stock fft in flashtool he needs to find out if it is unlocked.

Odp: [Q] Stuck on sony screen after x-parts CWM, while installing ultimate HD
Of course he can use flashtool. He must find stock Rom download and flash. But anyway he should install Sony update which is installing all necessary drivers. For installing CWM use this https://www.box.com/s/ydn80deft19ph4c1y8yg

if he doesn't know if his boot loader is unlocked then its locked, unless he picked it up second hand.

I managed to fix it with sony pc companion repair. Now i rooted my phone again. But i want to ask one more question:
How can i install custom rom? Should i install kernel first? And how to tell if my bootloader is unlocked because i checked and i saw that my provider allows it.
BTW isn't it called "bricked" when you're stuck on sony logo?

It's locked you woud not have been able to repair it with Sony if it was unlocked! You can't flash a kernal if bootloader locked you need to unlock it.

Odp: [Q] Stuck on sony screen after x-parts CWM, while installing ultimate HD
I have locked bootloader an I'm using Xperia ultimateHD 2.0.3 . After rooting you should install CWM from my link above and copy ultimateHD to your sd card and flash it. Check how on ultimateHD thread. After that probably you need flash stock Wi-Fi modules.

Don't touch /system. Don't wipe it, don't delete it, just DO NOT TOUCH IT.
And you will be fine

Your bootloader is locked by default, you have to unlock your bootloader.
Stock ROMs generally can be used with stock kernel but with non stock-based ROMs installing a custom kernel (that requires an unlocked bootloader) is a must.

Odp: [Q] Stuck on sony screen after x-parts CWM, while installing ultimate HD
You can install Xperia ultimateHD on locked bootloader, and you don't need to flash any kernels. Just tick "locked bootloader" in aroma and done. Everything work perfectly.

Aroma its a graphic rom installer, like windows or linux installer. If you have rooted phone use CWM installer from here :https://www.box.com/s/ydn80deft19ph4c1y8yg . Copy rom to your sd card .Boot to CWM (Keep pressing the Volume Down key after the Sony logo appears)
Wipe Data/Factory Reset
Mounts and Storage --> Format /System
Advanced > Wipe Battery Stats
Install zip from SD card > Choose Xperia Ultimate HD
Follow on screen instructions on AROMA.
After Complete Installation untick "reboot" and select reboot in CWM
And that's it :highfive:

Flashtool
Try flashing a stock firmware in Flashtool, good luck.

Now downloading the stock firmware using sony update service, will update about the situation when it is done

Update Service with an unlocked bootloader is a bad idea.

Try this.
http://developer.sonymobile.com/services/flash-tool/how-to-download-and-install-the-flash-tool/
Official flashtool to go back to stock rom.
And as the guy above told you, SEUS on unlocked bootloader is a bad thing.

Hi. I have same problem.
Just flashed FreeXperia rom and gapps. Phone wont to power up. Just geting blue led or green.
Any clue? My bootloader is locked.
tried to use official xperia update tool but it wont to recognise my phone (maybe i doing sth wrong :/)

No it's not. If you have root you can push cwm via adb.

I'm talking about Cyanogen Mod (CM) not CWM. Next time read carefully.

Dude,
As the others have said you cannot install FXP CM10 on a device with a locked bootloader.
As such your device will not boot, your options are to either.
1) use flashtool to flash a stock rom - instuctions how to use flashtool can be found on the forum
2) use Sony update service to flash back to stock - This is the easier option, but all your data will be wiped.
Once the device will boot up, if you still want to use FXP roms then unlock the bootloader first, or try a rom for locked bootloaders.
Either of the above should work for you.

yea phone works again fine on the stock

At least you show others, do not flash custom ROM if it's only for unlocked bootloader.
If you have locked bootloader you can't flash custom kernel and you will stuck in bootloop.

Unable to flash JB ROM by CWM

Hi there,
I am using Xperia Arc (LT15i - Rogers edition)
Current ROM: https://docs.google.com/file/d/0B_d8uWGbkaetcWIzcFJzdkVwUXc/edit?pli=1
4.0.4 ICS 4.1.B.0.587

Installed CWM 5.0 by RecoveryX

Bootloader: locked.
I was able to get into CWM to select JB ROM to install.
I've tried 2 different ROMs:
Racing Bean
SuperJB
However, when installing, the installation aborted and couldn't continue.
I cannot do anything with it.
Any solution you may suggest me?
Thank you very much.
(Extra info, *#*#7378423#*#* to access the service menu.
Service info > Configuration > Rooting Status. Bootloader unlock allowed: No with the ROM via Google Docs)

I'm pretty sure you need an unlocked Bootloader for those ROMs

Oh yes, thanks for pointing it out.
But as I've tried unlocking by following this topic
Bootloader unlocking
I cannot do Step 9
I've flashed lots of HTC phones but non of Sony phones I can do by this way

What happens if you do step 9? Are you sure you are in the right folder? Are the drivers correctly installed?
Maybe the guide on FreeXperiaProject Homepage explains it a bit better (cant post link since I have less than 10 posts)
There are also some good youtube videos (for example the one in the thread you posted)

The only thing it says was "Waiting for device" and never went through.
Also, the LED didn't become "blue" It's just like regular chagring, no matter how hard I tried
So,
I guess if there is someone's nice enough to make FTF version by their phone then I can enjoy JB on my Arc lol

Are you sure you are holding the Menu Button when you plug in the usb cable?
In the past i was always pressing Home Button and was wondering why the LED isnt blue

Yes, Menu one is on the right.
I kept it for so long but it's not turning blue ><

You press the menu button before connecting your switched off phone to the cable...
Also, do you have drivers?

Don't forget that on Sony phones you have to flash ROM and kernel separately.
ROM in CWM and kernel in fastboot.
JB ROMs need custom kernels and to flash a custom kernel you need to unlock your bootloader.
