Jeremy Phan: The Universal Rooting Tool should already support it. Flash, run the tool.
Mayank Kumar: Can I Update my xperia Ion at&t locked bootloader jell bean with this method ?
Jeremy Phan: It's already in the description and links.
heartthrob85: are you going to post a video about how can we update the lt28at to jelly bean by flashing an international firmware like a lt28h or lt28i with ICS and then we can use Sony PC companion/update service to update it to jelly bean, cause you break it down really well:-)
Jeremy Phan: Build #. Every region/carrier/build has a specific #, including generics.
If Build ABCD has a Jelly Bean update then installing Build ABCD's ICS version will get updated. You can look up your SI # in the *#*#SERVICE#*#* menu.
heartthrob85: whats SI build?
Jeremy Phan: Only if that generic build has an update to JB available (SI build).
The JB FTF has been posted. Description's updated.
heartthrob85: Hey Jeremy, i have a sony xperia ion lt28at with a locked bootloader running ICS and is rooted using your method....my question is i still havent got the JB update, so can i flash a generic firmware lt28i onto my phone using the xperia flashtool and then is it possible that i get the update?
Jeremy Phan: If the first link doesn't work, you have to use recovery, as stated in the description. You have to downgrade to ICS and flash through recovery.
Saul Fdz: Hi...i have a sony xperia ion LTE (LT28at) on AT&T with ICS 4.0.4 (6.1.C.1.111) with LOCKED BOOTLOADER!! How root my phone??
Jeremy Phan: 1. Wait for it to be released.
2. Download the FTF.
3. Flash your phone using FlashTool.
Chandrasekhar Jena: how can w e install latest JB . still waiting for firware from sony.
but wanted to flash without ATTfirmware not sure whether they will release.
please suggest or will you include any new video?
Jeremy Phan: What do you need? The processes are all the same and interchangeable.
Jeremy Phan: Can't be done. Needs to go to a service center.
CheezDaBarber: What can I do once the phone is hard locked (too many wrong unlock tries) ... I have right network unlock code from At&t, but phone is past attempted tries. How do I unlock to enter proper network unlock ...?
brian so: Hey again I know this is off topic but do you have videos for the xperia tl? Was supposed to go ion but they don't carry them anymore
Jeremy Phan: Flashing software onto your phone doesn't void the warranty. Only when you unlock the bootloader... which can't be done for carrier-branded phones.
brian so: hi i am looking to upgrade to the ion. i was wondering will this void my warranty? in case my phone gets messed up
Jeremy Phan: 1. READ the DESCRIPTION. There are direct root methods now.
2. If this video still applied, you'd still have to flash your HSPA kernel.
TheMCPlayer12: And I'm on wind so I don't LTE so do I still have to flash it?
TheMCPlayer12: Will this work on Ice cream sandwich 4.0.4?
Jeremy Phan: It's out yet. When it is, download the FTF and flash it.
Root hasn't been published yet since the firmware isn't out.
MEGA F4IL: Can you make a tutorial for updating Xperia Ion LTE to Jelly Bean with Root with locked Bootloader?
Jeremy Phan: Power off.
Use Update Service or FlashTool to wipe/reinstall the firmware.
dedeclarke: I'm just trying to find a hacking software to hard reset my xperia ion lt28at. this phone was given to me with a password on it one they conveniently don't remember. The phone is useless with this pattern lock. Any clue how to do this?
Jeremy Phan: Something that has ADB is running. e.g. FlashTool. Close it.
Open Task Manager and terminate all ADB processes.
Jorge Luis Torres: try it but I get the adb is out of date, you can tell me why it happens?
Jeremy Phan: Nope. SIM/network unlocking has NOTHING to do with the software/flashing your phone.
Pay for an unlock code.
diego quan: Hello, i want to know if rooting the phone and upgrading will also unlock my phone?
its a LT28at..
Jeremy Phan: H = HSPA only, Asian frequency bands. e.g. 900 Mhz.
at and i are North American LTE: 1,700, 1,900 and 2,100.
According to T-Mobile support, unlocked AT&T LTE phones work on their network so it should work. (Google msg #183640.)
Quailallstar1: Thanks for the reply. Looked up their tool and they don't list the LT28H in their database. They only show the LT28at & LT28i; what's the difference between all these three models?
Jeremy Phan: T-Mobile uses 1,700, which should work.
Use their compatibility check tool. "t-mobile compatibility check"
Jeremy Phan: What won't work? You can flash any firmware onto the phone. What's happening? Which firmware are you trying to flash? Need more info...
Quailallstar1: Great video. Do you know if this phone will work with tmobile and their LTE when it goes live?
rebecablacksucks: When i try to flash it to downgrade it, it will not work. any help?
Jeremy Phan: Sorry, but if you can't follow a detailed, step-by-step video guide on rooting your specific device, you shouldn't be messing with custom anything.
Read the description and all the links.
Anthony Pyrtle: im a lil confused on how to download the cusom roms n how to do clockworkmod recovery n all that i need help
Anthony Pyrtle: i cant figure out how to download custom roms how to put clockworkmod recovery r anything i need a lil bit of help
Jeremy Phan: There are custom ROMs built upon OEM/Sony firmwares that work with locked bootloaders.
Anthony Pyrtle: if it says my bootloader cant be unlocked does that mean i cant put a custom rom on it and all that

xXSickSippXx: Has anyone tested this on LT28at? I don't want to brick my phone.
