I am using a R800at on T-Mobile, stock (though it is sim unlocked). If AT&T actually ever releases any updates for the R800at, will I be able to get those OTA or will I have to use PC Companion or SEUS? If I did have to use one of those programs with a PC, will it keep my apps/settings, or will it wipe everything during the update process? Thanks!

Hi I have a Canada Rogers R800a running R800i firmware bootloader unlocked with doomloards kernel on AT&T USA network and was wondering if when someone releases the official R800at firmware will I be able to flash it to my R800a because some of the stock apps I can use like the uverse app.
Thanks,

Honestly, it's anyone's guess, but it's likely as long as you are able to unlock the bootloader.
how did you do it
i was on the idea that the bootloader of the r800a from rogers was not unlockable du to rogers decision to this day i dint manage to unlocked it and i flash a lot of phone like the nexus i cant put my xperia in fastboot mode
If and when the r800at firmware is made into a .ftf, it's very likely you will be able to use it on your r800a because they're both GSM. It's hard to know if all the stock apps will work correctly since some may have problematic DRM though
Well, it's available. I'm running the R800a 2.3.4 FW on my R800at so I'm pretty sure you can run the R800at FW on the R800a. The thing is, you will be giving up a lot of extra features (screenshot, tethering, etc).
OK I have a Rogers Play. I flashed my Rogers Play to stock UK 2.32 to get root because i lost it after i updated to 2.3. So then i did the over the phone update and i had 2.3. now it's asking me to update to 2.4. If i update to 2.4 would I be loosing the UK version of the firmware and going back to Rogers firmware?
If your on the UK firmware you'll still be on UK firmware after the ota update. I'm on Rogers too but I haven't been on their firmware pretty much since I bought it when it came out they too slow with updates. And now I've unlocked my bootloader so I don't ever worry about not having root

did you use Flashtool? Does UK version work on Rogers Play perfectly (differences between US-r800a and UK-r800i versions)?
I'm planing on flashing my arc, but I've a few questions first.
the method I'm using is via wotan because I heard is the easiest one (I know i've to paid, but is just 1.99 euro).
I have a xperia arc lt15a 2.3.4 firmware .62, directly from my carrier, ICS hasn't been out for my country yet, I want to flash to the Generic Trade US (4.0.4) (LT15a) once that I flash to that version via wotan it will be compatible with my carrier?? my carrier is from central america and my bootloaders are locked and I dont want to "lock" my phone. I dont care if I will still be only compatible with my carrier, but I just want to make sure that I would still be able to make and receive calls...
another question is: if I dont like it ( ICS ), can I go back using PCC?? or from now on I just have to use tools like flashtool or wotan to change version??????
You can flash 4.0.4 with flashtool, it's free.
And no , after you flash ics you can't go back to gb by pc companion , because your phone will be debranded, so pc companion will say that you have the latest firmware in your phone.
You can get back to gb , by flashing a gb rom by flashtool or using wotanserver.
but by flashing via wotan or flashtool it will not lock my phone and make it unable to detect my carrier (make calls, sms, etc..)??? because this happen to me once with my iphone that the jailbreak update the baseband and got myself a very expensive ipod

better flash generic global world version ftf via flashtool.
its simfree & no problems.
I purchased an experia play r800at and it came already sim unlocked. I decided I wanted to go further so I use the paid method to have my bootloader unlocked as well. After all is said and done I install a custom rom and my phone does not recognize my sim card as if it's not even there. I tried a few different custom roms and they all did the same thing. When I go back to stock rom though I have no issues at all. I had also purchased a r800i white phone, but with my white phone I went through sony's way to unlock the bootloader instead of the unofficial way I used with my blue one. I now can do what ever I want with the r800i without any problems, but am still stuck with using the stock rom with my r800at. Does anyone have any advice on how I can fix this? The white phone is only a 2G phone so I gave it to someone else to use cause the blue one is 4G and I need that more. I would really like to install an ICS rom on my r800at so if anyone has any ideas I would love to hear them and try them out. Thanks:cyclops:
So you want to install a ICS official and you have the bootloader locked?
Yes you are sim unlocked. BUT you need to have your bootloader unlocked as well. They are both clearly 2 different things. In order for you to intall customs rom your bootloader needs to be unlocked not sim.
How do I unlock the phone? I currently have Cm11 on it.
I want to ditch rogers (terrible service) so what do I need to do to unlock it?
side note, when I got the phone it was via future-shop warranty and they gave me a fido version and put my rogers sim in it, did they unlock it then?

Since Fido is really owned by Rogers, your Rogers SIM may work in the phone if it was originally locked to Fido. To check whether it's unlocked or not, try putting in a non-compatible SIM (like Bell or Telus) and see whether it prompts you for an unlock code. If it does, you would need to purchase a code online or request one from the carrier. If it wasn't on Android 4.3 prior to the CM11 installation, you may be able to install stock Android 4.1.1 and free unlock. Either way, whether you are free unlocking or using an unlock code, you have to be on a stock ROM for it work. You can check your phone's settings and see what baseband and bootloader versions you have. This will tell us know whether you should flash stock 4.1.1 or 4.3

Baseband is I747MVLUEMK5 bootloader I have no idea, I just used odin to flash CWM.
I'm open to flashing 4.1 to get a free unlock then going back to CM11

I747MVLUEMK5 is ver. 4.3 and you almost certainly have the 4.3 bootloader as well. With this, unfortunately, you can't downgrade to 4.1.1 where the free unlock option is available as any attempt to do this could brick your phone. You would need to request an unlock code from the carrier, if eligible, or purchase one online. There have been reports also that the unlock codes don't work when you are on a custom ROM so if you buy one online and it doesn't work, you will have to flash stock 4.3.

ok, which carrier would I have to talk to, it was a fido phone as mentioned previously. Also is their a possibility I could downgrade to 4.1, or is it a guaranteed brick?

You would need to contact Fido since it was originally on their network. I'm afraid nobody has yet posted a method to allow you successfully downgrade to 4.1.1 and still preserve the free unlock functionality. You could follow some instructions posted in this forum to downgrade to 4.1.1. However, this wouldn't allow you downgrade the bootloader/modem which is required for the unlock.

I found a way to downgrade from 4.3 to 4.1.1 or 4.0.4 stock. (for Bell).
I bought and used Mobile Odin (available on the play store). Anyhow, it flashes the stock rom and not the old bootloaders. Once you're on 4.1.1 or 4.0.4 the problem is that *#197328640# no longer works. Basically when you type that ServiceMode comes up, but all the options are gone. I believe this is because they locked those features on the new bootloader (which is still on the phone after the Mobile Odin downgrade...)
Unlocking this phone has become a major pain in the ass.

You are quite right. Sam and the networks are winning this time. You can indeed use Mobile Odin to downgrade the system (ROM). However, there hasn't been any reports of a successful downgrade of the bootloader. Therefore, even if you downgrade without bricking the phone, you can't free unlock. Tough but you will need a carrier unlock code.
