Yeah, Ill go to ATT tomorrow and get a new one, had a red light after doing the softbrick recover steps but as soon as it hit minimum level black screen and no response again

I am getting a new Ion sent to me from ATT, the rep I had from warranty, Nicest lady EVER they even waived the 1-2 day shipping fee because Im away on business. Now Some may read this and say I am abusing the warenty system by lieing to get a new phone I broke it I should pay. Well being an ATT customer for about 10 years I do pay but also, I saved many people from trying this on their own by risking my device for the community :)
[Sony Xperia S, Acro S, Ion] namila007:
Can we unlock (bootloader ) any ver of ion models? i mean LT28i , LT28h, versions?
[Sony Xperia S, Acro S, Ion] Spectre51:
Yes the LT28i (non Rogers version) and LT28h can be unlocked.
[Sony Xperia S, Acro S, Ion] trf000:
To be clear, only if your phone came with those roms. if you have the lt28at or the lt28i Rogers version and you flash another rom like the lt28h or lt28i non Rogers, your bootloader is still locked.

Some people, not you Spectre51, still seem confused by this.

I have a LT26i and its bootloader is unlocked, but is it posible to lock it again and get o official rom and kernel to it?

bl unlock problem

Hey there everyone,

I've got a lt28h and in Service Info>Configuration it shows 'Bootloader unlock allowed - Yes'. I followed these steps, went in to fast boot and installed the driver, but after I open the command prompt and type in the first set of strings to see if the device is connected, I get the <waiting for device> string and nothing happens. The blue led does come on, but doesn't stay for very long. All this on a Windows 8 Pro 64bit Alienware machine.

What am i doing wrong? :(
[Sony Xperia S, Acro S, Ion] Levopron:
Thank you.!
[Sony Xperia S, Acro S, Ion] wicozani:
I suspect you may not have USB Debugging checked under Settings>Developer options (if you have ICS OS).
[Sony Xperia S, Acro S, Ion] superage:
I think I have the same problem like user:siddip

I turned my Xperia ION while pressing Vol+ then I can see blue led lit for few seconds, I connect USB to PC.

My PC pop up to install the driver for fastboot device, but before I select the driver, its already given status device unplugged, so I have no time to install the driver.

Any one have an idea ? Thanks.
[Sony Xperia S, Acro S, Ion] Spectre51:
Right click the inf file (driver file) and choose install before trying g to get into fast boot. I did that and had no issues.

bootloader unlock sony ion lt28i

Thinking of tryng this on my Ion lt28i even though it says - Rooting Status: Bootloader unlock allowed: No - Sony website has it listed as one of the phones and from the post id says this is promising, before i take the plunge - Any thoughts suggestions or advice?
[Sony Xperia S, Acro S, Ion] Spectre51:
It will not work. If it says bootloader unlock allowed NO it means NO. You will get a code from the Sony site just fine but you can't enter fastboot mode to use that code.
[Sony Xperia S, Acro S, Ion] explorerbrett:
thanks for the fast reply

thanks for the fast reply kind sir! I hope its ok i ask another question,

If the bootloader (lt28i) cant be unlocked, i need to root this device, ive tried Root_with_Restore_by_Bin4ry_v18: - with out any success, its not a matter of procedure as i was successful with a friends lt28i

Any suggestions are greatly appreciated - thanks again
[Sony Xperia S, Acro S, Ion] thanitos:
Use flashtool it works better for some, same procedure as binary just click the pad lock icon
[Sony Xperia S, Acro S, Ion] Spectre51:
What firmware version are you on? What happens when you try rooting? I take it you have a branded LT28i?
[Sony Xperia S, Acro S, Ion] explorerbrett:
When rooting, it all goes well and I hit restore on the device but nothing happens - My service providers is mts allstream this is the second one of the same type of device I've tried I believe the first had the initial ics update that sony released and this has both - the intial Lt28i was ics 4.0.1 and mine is ics 4.0.4 - I hope that was enough info? Is There A Specific flashtool or something else you can suggest? Maybe a way to go back to 4.0.1? - -

Thanks again, you guys are awesome !!!!!!!
[Sony Xperia S, Acro S, Ion] thanitos:
I used the. Bat binary released it worked once then I reset my phone to stock and it never worked again. I just download the new version flashtool is on you'll still need the backup and restore app like you did for binary and just plug your phone in open flashtool then click the pad lock and follow the steps on screen

Go to Settings - > About phone and tell me what build number it says.
[Sony Xperia S, Acro S, Ion] explorerbrett:
build number 6.1.e.3.4
[Sony Xperia S, Acro S, Ion] Spectre51:
Okay that would be why root isn't working for your ion. Anything past 6.1.E.2.68 has had the root exploit fixed. You need to flash back to 6.1.E.2.68, then use bin4ry's tool to root then OTA update to 6.1.E.3.4. That will keep root.

If I can get a ftf file of 6.1E.3.4 I can make a prerooted version for everyone.

We still haven't had anyone release a 6.1.E.3.4 ftf for the LT28i....been looking for it. What region are you in? Does your phone come with stock carrier apps?
[Sony Xperia S, Acro S, Ion] explorerbrett:

i am quite puzzled.

i followed every step but i cannot get the phone into fastboot mode (xda & sony guide). Bootloader unlock allowed says Yes.

windows says that it cannot install drivers and quits the installation. i only push the volume up button and plug in the usb plug.

i have had an motorola atrix and a galaxy s before and there the fastbootdrivers where installed automatically. i have no root yet.

what am i doing wrong?

edit:

actually windows finds a fastboot device shorty. but a few seconds afterwards the sony emblem on the smartphone shows up and then it is displayed as "android" in windows under devices...

after reading a bit i find a little help. so i found out that i have to be quick with the manual install of the driver.

does it actually matter which firmware version i am running on? i have the newest on a international device.

i don't understand -- i've triple checked everything yet it still keeps failing....sony's website no longer allows you to put in 15 characters for the IMEI so i chopped off the last one and entered it in after it gave me an error message at first for inputting the full imei.
