[Q] R800a can not OTA update or enter fastboot, root problems? mode.

I recently purchased a R800 from someone on Craigslist. The phone is already rooted, permanantly I think since it is rooted after doing a factory restore. It is not sim locked, I believe its factory unlocked.
I tried to do the OTA update, which downloads, but fails to install. It appears to get about 3/4 of the way done, reboots and gives me an "update failed" message.
I wanted to unlock the boot loader, I got the unlock key from SE. I must of tried 10 times to get the phone to boot into fastboot mode, it NEVER does it. It simply boots up normally. I even got an app that makes it easy to reboot into restore or fastboot modes (just click an option and it reboots), however just like before the phone simply reboots normally. I even did a factory restore prior to trying the update... no go.
Should I try to remove the root access? Is this what is giving me all the problems. I was able to successfully install root explorer and titanium backup and both of those programs worked fine.

Is your phone sim locked? Sim locked phones need to be unlocked before able to unlock bootloader or fast load. After you unlock bootloader make sure you never ota update.

Your phone has a locked bootloader and a factory lockout on fastboot.
Best advice to you is flash the r800a world generic 2.3.2 root it with gingerbreak then ota update. Use a program called wontanserver as its super easy.
Dont get anyone to remove your factory locks on fastboot until you read tons of threads on these fourms from the last couple months.

Ok, lets see....

My phone is the R800a. It was my understanding that this phone was never locked (factory unlocked). It came in an official Sony Ericsson box and has no carrier branding on it what-so-ever. It was not purchased through a carrier. It does have a weird stock data APN called "Telekila"?!?!?

Doesn't wontonserver require credits to run? How expensive does this get?
I didn't know the phone could have a factory lock on the bootloader. I did go to the SE website where you get the unlock key and it was successful in giving me a key... Well I shouldn't exactly say "successful", it did give me a key code to use if and when I can unlock the bootloader, weather or not that code is actually legit remains to be seen. I'm a bit skeptical now since you said the phone is bootloader locked from the factory. I though SE was allowing their phones to be unlocked. I recently unlocked my Motorola Atrix and was expecting to do the same with this phone.
Thank you guys for the advice. I love this phone so far but I can't wait to get a custom rom on it

It uses credits but they are free.
There are currently 2 gentlemen on these forums that can remove your fastboot locks and unlock your bootloader.
Have a look for thier threads on this matter

I would like to have this done now, so gentlemen, whomever is able to do this please message me and we can work something out. Im dieing to get a new rom on this awesome phone/game console.

If you need help with unlocking your phone contact Alejandrissimo he does Unlocks

I flashed the r800a world generic 2.3.2 rooted it with gingerbreak then ota updated.I get the same thing as DMpire , reboots and gives me an "update failed" message.
Is this because I removed some of the stock apps that came on the phone after it was rooted? Anyone know about this?
Does it matter if the SD card is mounted or not?

Removing stock apps then trying to ota isnt going to happen. Reflash, root, ota, then remove your stock apps

Is there any easy way to do this? can I reflash it as it has a locked bootloader, or do I have to get the bootloader unlocked?

[Q] Phone bricking per OTA - strange

Hey Folks
I tried now 2 times to get on the new Firmwareversion 4.x for the Arc with root.
Every Time i tried to Unlock per OTA the Phone bricked. So the Bootloader must be open.
I don´t touched the Bootloader, but i think the Bootloader is open, because the Phone had SimLock and i unlocked the phone with SETools with Testpoint Methode.
How do I know if the boot loader can be unlocked on my phone?
It is possible to unlock the boot loader for certain releases of our 2011 Xperia™ phones, such as Xperia™ arc, Xperia™ neo, Xperia™ pro and Xperia™ PLAY. Your phone has to fulfill a number of requirements, for example, you can’t unlock the boot loader if you have a SIM lock protected phone. There are other requirements as well, depending on your market and the original configuration of your phone.

So the Bootloader must be open in a way am i right? But i can still update with PCC or SEUS the Firmware
Where can i check the Bootloader Status
Thanks in advance for Help Dudes

Setool would have unlocked the bootloader, so have a read of the unbrick thread in the dev section.

Upgrading from .42 to .62

I have a UK Xperia Play on .42 firmware with CWM recovery and root provided by Zerg Rush.
I've heard that I need .62 to install some of the custom firmwares.
.42 appears to be the latest firmware I can get OTA. I'm not sure the best way to upgrade to .62, do I need to go via .58 or similar.
Does it matter that I have a UK phone?
Is it possible to preserve my settings?
Will I need to re-root at any time?
In the long run I am looking to install DooMKerneL and probably something like Jokawild.

You have to flash the ftf file for your phone
Here is a link to 99% of them
http://forum.xda-developers.com/showthread.php?t=1589399

If you install a new firmwares. Maybe you'll need to root it again..
But since the devs makes the pre-rooted custom ROMs, you don't need to root it anymore

I don't have an unlocked bootloader. Is this required to install a custom ROM even if I have root?
Is there any disadvantage to unlocking the bootloader?

No unlocked bootloader = no custom kernels/ very limited to roms
Only disadvantage is it voids your warranty, but being that you have root, you have no warranty anyway lol

I was in the same position as you. I wanted to get a custom ROM and be able to overclock my phone. After a few annoying errors, I finally got it up and running
Basically, your going to have get your phone into flashmode and then flash the .62.ftf file on your phone. Congratualtions you now have .62FW (although youve lost root).
To get root on .62 FW, your going to have to flash a custom kernel (I did DoomKernel v14). To flash a kernel, your going to have to unlock your bootloader. After unlocking and flashing the kernal, your phone is now rooted.
And plus the positive side Ive heard is that you CANNOT brick your sony eircsson phone. (well you probably could but there is a very very slim chance of that happening).

Thanks.
It seems I can't unlock via the regular Sony way as Unlock Bootloader is set to no.
I think I need S1Tool or something similar (maybe something I have to pay for) to get my bootloader unlocked. I'll check the forums a bit before I ask any questions that haven't been asked before

i did it via omnius and it work great, i just payed 19.76 for one single unlock credit on gsmserver

not sure why people say that root voids warranty.
i have ATT play 4g and it was having hardware issues, so i flashed the stock ATT software back and took it to the store. i got a "new" one in the mail two days ago.

I also sent my rooted xperia play that had the slider broken to CLARO El Salvador and they repaired it (They flashed their ROM again XD)
Now i have unlocked bootloader but who cares i have premium insurance

Any modification to the software voids the warranty..

Update:
I downloaded s1tool and connected the test point to the ground. Everything seems to have worked so I am guessing my bootloader is unlocked. Is there anyway I can verify this, or should I just attempt to install a kernel?

Try to put the phone in flash mode (green light) if it recognizes it, it's unlocked. I think there is a sequence or symbols/numbers you can do to check it, but idk what that is since im a r800x

To check your unlocked bootloader you need to dial: *#*#7378423#*#* , then go under, Service info > Configuration > Bootloader unlock allowed: Yes/No.

Problem with Recovery Mode

Hello,
I have a Sony Ericsson Xperia Play and I'm starting in the android world, I've read a lot here on the forum already informed me about what I do to boost my smartphone, I wanted to install a new ROM, and follow what the most part of the posts say, I started by installing the most current Baseband, do Root (all this through FlashTool), install the X-Parts, put the CWM for Stock GB, but when I restart in recovery mode it always starts in normal mode, never enters the recovery, nor with the selection keys or through the X-Parts.
The Smartphone has a locked bootloader, and did what they say on the website that Sony only in internal settings says that this smartphone is not entitled to have the bootloader unlocked.
Can you tell me what I'm doing wrong? Or if there is no solution without the Bootloader Unlocked?
Thank you for availability
Best regards,
Cristóvão Guerra

Search for xparts on here and download one of the older versions. For some reason xparts v5 from the play market doesn't work. Also what version of Xperia play do you have? R800x (Verizon) or do you have GSM version and if it says you can't unlock boot loader you'll have to pay 20 dollars to get it unlocked from an unlock site. Also you can install stock based roms while you're bootloader is locked if you donf want to pay to unlock it.
Please press thanks if I helped.

Do what abdel12345 said for the CWM. If you have an r800x Xperia Play it is unlockable i think. My phone said it couldn't be unlocked either but when i went through the steps i came out with an unlocked bootloader so i think verizon just wants to trick the r800x users.

i have a R800i, v. 2.3.4, baseband 4.0.2.A.0.58, so can you tell me who I have to talk to unlock the bootloader?
