Thanks. I was wonderning because you said "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". :confused:

So you mean I can restore TA directly while I am on my custom ROM? --> Then the phone will be on custom ROM, Bootloader locked, TA restored?

Next I can just flash back the stock FTF and everything will just be fine?
[Xperia SP General] DooMLoRD:
well the minute u restore TA and if you are on CUSTOM KERNEL the device will no longer boot...

you need to be on signed stock kernel for device to boot :D
[Xperia SP General] Androidkeeda:
Only TA restore is enough to relock bootloader ? So we dont need to relock bootloader from flashtool blue button process??
[Xperia SP General] Siddhesh:
Ta restore will also relock ur bootloader
[Xperia SP General] infinitylook:
Good day. Who have unlocked BL here? Is the DRM bravia engine really lost? I have a Z1 COMPACT and unlocked the BL bUt DRM in walkman (download music info) and the X-reality still works. I wonder if it's the same for SP. I want to unlock my BL SP as well but wondering if those feature will be lost
[Xperia SP General] Siddhesh:
Yes it will be lost forever so take a backup with TA backup tool before unlocking bootloader
[Xperia SP General] infinitylook:
Have you unlock yours? Can you confirm to me that download music info is not working and that there is no bravia engine? Because on my z1compact there is x-reality and drm though i unlocked bootloader. In my z1 compact it seems nothing is lost
[Xperia SP General] Siddhesh:
I have locked and unlocked bootloader many times after losing drm keys only bravia engine will stop working, download music info will work without problem. I think X-reality is different from bravia engine that might be the reason it still works even if we unlock the bootloader
[Xperia SP General] infinitylook:
Oh i see thought download music info needs drm. How about track id?
[Xperia SP General] Siddhesh:
Works
[Xperia SP General] infinitylook:
Ok great i guess nothing to lose then when unlocking. Don't really care for bravia engine
[Xperia SP General] Soulblinded:
Do i have to have stock ROM or i can unlock on CM11 or eXistenZ 3.3.0 ???
[Xperia SP General] Siddhesh:
U need to be on stock just to be safe
[Xperia SP General] TheUnknownThing:
The file is uploaded but I have a problem.. I do everything exactly (BTW unlock bootloader:yes) what the guide says but I run into a problem. (Check the picture) It says oem unlock failed. I do not know why this happens, I have superuser access, everything is stock but this problem occurs. Can someone please tell me what I have done wrong? Cheers!
[Xperia SP General] TheUnknownThing:
Ignore the previous post. I fixed it some how. The IMEI number I entered was wrong (was 15 digits instead of 14) and fixed that then another code came in and did the same exact same thing except with flashtool. My phone rest (which is supposed to happen) and I'm guessing it worked because as I tried unlocking my phone through cmd, it said phone already unlocked. Phew! Now I can play with CM11!! :D

You are in the wrong forum friend, head to S4 forum, this is for xperias (xperia sp)
[Xperia SP General] [BRA] Giovani:
To confirm what I understood:

1) Backup TA and Unlock bootloader:

-Bravia Engine will not work.

but

2) Restore TA and re lock bootloader:

-Bravia Engine back to work?

relock bootloader first then restore TA

can we unlock bootloader while in custom ROM?
[Xperia SP General] Raeshabu:
I believe, yes we can.

I'm on Stock-based ROM (ArchXperia) back then when I accidentally bricked my phone.

Only option left is to unlock bootloader and install custom recovery and reflash.

So, yes. AFAIK. :D

I am using CM12 LBL version can i unlock boot loader without reverting to stock?
[Xperia SP General] sadi6801:
it's better to take a backup from your ta partition so flash stock , backup ta partition and then unlock your boot loader!
[Xperia SP General] Aadi:
My phone's warranty is gone anyway so there is no use for DRM keys. So can i directly unlock from CM 12

Just restore the TA Backup that you already have, it will relock the bootloader.

I was on the site but i cant find the Sony XSP! Can you send me the link????
[Xperia SP General] ComanderKeen:
same for me. Link to XSP is not available anymore
[Xperia SP General] Dims_Camper:
xsp section for unlocking bootloader has deleted, there is another way to unlock?
[Xperia SP General] dallivadr:
Which option you pick on the Sony site doesn't seem to matter as much as the IMEI code does. I ran into the same issue (no 'Xperia SP' in the device list) about 2 days ago, so I submitted two requests - one for the Xperia S and one for the Xperia SL. Both requests were made using my IMEI and Sony replied with the same unlock code for both requests. Running the 'oem unlock 0xKEY' command worked just fine with the returned code and the boot loader is now unlocked.

Hopefully this helps someone out!
[Xperia SP General] Dims_Camper:
so, no matter what section that im using, the website always generate the code for unlocking bootloader? Thanks.
[Xperia SP General] dallivadr:
I haven't tried all the devices in the list, so can't say for certain, however it appears to be the case. S and SL confirmed though.
[Xperia SP General] Dims_Camper:
Xperia SP has been added again to bootloader unlock list, ggwp.
[Xperia SP General] steveglowplunk:
I want to send my phone back to warranty and I have some questions.

I have unlocked my bootloader and flashed a custom rom (and a custom kernel too). I have NOT backup my TA partition. The relock bootloader intruction in op doesn't seems to be suitable for my situation. What should I do? And where can I download the stock rom for c5303?(sorry I'm kind of noob at this)
[Xperia SP General] abdulaziz766:
The same problem

i have the some problem like u, do u find any solution?
[Xperia SP General] casouzaj:
I had a Xperia SP smartphone some years ago. In general, fastboot mode is meant for unlocked bootloaders only. Having bootloader unlock allowed stating yes in the service menu doesn't mean that your bootloader is unlocked, only that you are allowed to unlock it, if you really want.. For locked bootloaders flashmode (volume down whist plugging the USB cable in) must be used instead.

To check your bootloader status, enter the service menu and go to Service tests > Security. If ALL the DRM keys you see there have their statuses showing [Key OK][Active], then your bootloader is locked.

Anyway, both flashmode and fastboot modes are temporary. You must have the ROM or kernel or whatever other piece of software to be flashed, ready, with the connection window asking you to connect your phone in that particular state.
[Xperia SP General] jvu:
Unlock not working

Hi, i'm tryng to unloack the bootloader, I looked in Service info > Configuration > Rooting Status and it says: Bootloader unlock allowed: Yes

i tryed with cmd, other software, requesting the key with 15 digit imei and also 14, but unfortunatly the result is always the same:

(bootloader) Unlock phone requested

FAILED (remote: oem unlock failed!)

finished. total time: 0.075s

Any idea on what's the problem?

Thanks in advance

Can anyone pls suggest me the detailed way to install a Custom rom in my Xperia Sp c5302..
[Xperia SP General] skojevac:
Hi there,

Hate to bring this up, but would appreciate an answer on a questions regarding unlocked bootloader since there is no definite answer in the thread, and I did read all of it.

Now, I have a rooted phone since day one, made a backup of TA partition first thing that was available, even went that far to obtain a code to unlock bootloader, but never really got that far to actually unlock the boot loader. Right now I'm running on a 4.4.4 cyanogenmod rom.

So, the questions are

1. Can I unlock boot loader from a custom rom, since I have made back up of TA partition do I really need to downgrade?

2. Am I going to loose existing recovery and android?

3. If "yes", what should I do to flash new recovery?

Thanks in advance to anyone who can answer.
[Xperia SP General] skojevac:
To answer my own questions

1. Yes, it's possible to unlock boot loader with custom rom, there is no need to downgrade.

2. Recovery and existing rom not lost, only android is reset to fresh start.

I now experiencing battery drain and overheating issue, but that's another thing. Need to flash another rom now.
[Xperia SP General] Evilmonk100:
to relock xperia sp bootloader requires any file for relocking? or just need to flash only kernel.sin file. plz reply.

is anyone having xperia SP TA partition backup file if yes then plz share me a link so that i can download.

---------- Post added at 12:40 PM ---------- Previous post was at 12:28 PM ----------

how to restore TA using flashtool. if you had a xperia sp TA backup partition file then plz share me a link of that. bcz when i unlocked bootloder i will not taken backup of it.
[Xperia SP General] casouzaj:
Never, ever,, use a backed up TA image file taken from a phone into another phone. You will, certainly, turn it to a paperweight, and there is no known way to fix it by software means.
[Xperia SP General] Evilmonk100:
you are saying that TA backup file of one phone will not work for another phone of having same model and specification right?
[Xperia SP General] casouzaj:
Yes..The TA file contains all the DRM keys. It is unique for each device.
[Xperia SP General] Evilmonk100:
is there any way to gain lost TA backup files after unlocked bootloader and custom rom installation?
[Xperia SP General] casouzaj:
Unfortunately, not. You see, there's this thread, https://xdaforums.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672, which claims to be able to restore some functions which are affected by the loss of the DRM keys (not the keys themselves). I have never done it myself. The problem is that it is intended for the Z-series, not the SP. Perhaps you could contact the developer and get some ideas.

Hi All,

I am seeking help from you guys to fix my mobile. Pleaseeeeeeeeeeeeeeeee................

I'm new to this forum. I have read some posts on rooting/unrooting/flashing etc. But i'm at no point what to do with my mobile.

Here is my problem.

1. My display/touch screen glass was broken a month ago. But the handset was working perfectly even touch sensitivity was good. only problem was the glass damaged so badly

2. I ordered for the display/touch screen glass. Then i went into the Youtube to see how to fix the glass. I did everything as they said in that and glass was fixed

3. I was so happy that i fixed and then i switched on my phone. It took me to the Boot screen. Below are the contents showing on my screen.

hi all

[Battery %Mod & theme blue] for [Erobot V2.3P Tablet UI with MultiWindow][P6800][Deodexed]

just replace SystemUI.apk in system/app
[Galaxy Tab 7.7 Themes and Apps] edan1979:
Thanks a lot with the bat mod
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
So this mod can change the phablet UI to tablet UI in erobot v2.3P ?
[Galaxy Tab 7.7 Themes and Apps] ssaass:
no

you have to change the DPI = 176 Manually
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
Tks, is Play store working without compatible issue with this DPI?
[Galaxy Tab 7.7 Themes and Apps] ssaass:
working perfectly :good:
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
I tried as your instruction - change DPI (both ro.sf.lcd_density=213) to 176 in buildprop, overwrited the SystemUI.apk with yours, set permission - but it is not working with error message "unfortunately, systemUI has stopped"

Please tell me exactly the steps you did to make it work!?

Tks in advance.
[Galaxy Tab 7.7 Themes and Apps] ssaass:
1-Edit your build prop by adding the line qemu.hw.mainkeys=0 at the very bottom

2- Flash the P6800 V2 MultiWindow file

https://docs.google.com/file/d/0B7yxeu9x48ILZVZsaDVlQ0k4SGc/edit?pli=1

3- change DPI (both ro.sf.lcd_density=213) to 176

4- now replace SystemUI.apk in system/app

Did all the above steps but still not working. Same error "unfortunately, systemUI has stopped" & "unfortunately, TouchWiz home has stopped"! :(
[Galaxy Tab 7.7 Themes and Apps] edan1979:
You need to clear touchwiz data

anyway... out of boredom... i create a flash able zip file for it...
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
Tks so much, so we still need to follow all 4 steps as ssaass instructed, and in step 4 we flash your file instead of replace the apk?
[Galaxy Tab 7.7 Themes and Apps] edan1979:
yup... just flash the files on step 4.
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
Only flash your zip, no need step 1-3?
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
I did as step 1 - 3 and flashed your zip but no luck. Still got the error messages "unfortunately, systemUI has stopped" & "unfortunately, TouchWiz home has stopped" and didn't know how to clear the TouchWiz data without working launcher.
[Galaxy Tab 7.7 Themes and Apps] edan1979:
just swipe down to open the notification... there are setting button there... just click that... and go to application manager... go to all tab and find touchwiz and clear data...
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
Well, the SystemUI has stopped too, so there is no way to open the notification bar :(
[Galaxy Tab 7.7 Themes and Apps] edan1979:
did you use eRobot rom?
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
Yes, v2.3P
[Galaxy Tab 7.7 Themes and Apps] edan1979:
hmmm... try flash the battery files without flashing the multiwindow.
[Galaxy Tab 7.7 Themes and Apps] khangozzy:
Already tried only to flash this zip before I tried with 4 steps.

Both had same errors with TouchWiz and SystemUI. :(

[Galaxy S 4 Q&A, Help & Troubleshooting] xRyudo:
Alright, this is a frustrating issue that I've been having since day 1 with WhatsApp, and it's not even just SGS4, but with my old SGS too.

Problem:

Phone screen turns off while on WIFI, after a while of inactivity, WIFI still seems to run, but WhatsApp lost connection and takes a long time to reconnect, and usually requires a full restart of WIFI.

This does not happen on 3G for me, it only happens when WIFI is active.

Things tried:

- Turn off 3G entirely, so it only runs on WIFI.

- Reinstall WA

- Restart phone.

- Do a clean install of firmware (on my old SGS).

- Test it out on new phone~ (Brand new SGS4 i9505)

I don't know what's causing this, can anyone please help me figure this out? Let me know if you need more info.

is your router set to "always connected" or does it disconnect after sometime if no data comes in?

maybe i'm wrong but if it's only a wifi problem you maybe should look into your router settings.
