{Q} Do I have a R800x Verizon brick now? Advice please - FIXED W/O UNLOCKING !

Hi,
So I think I made a brick. Here is what I did to mess up my Xperia Play. I had rooted my device, and installed Cola ROM via recovery Nandroid method. Everything was fine after I did a small mod to make the gamepad work properly. Months later, my phone started running slow and I decided(yesterday) I wanted to go back to stock. I booted into CWM via an installed app on phone. When I was in recovery, I made a new nandroid, then I went to restore. I chose advanced restore and only restored system. :crying: I don't know why I did this, I thought it might end up bad. The process completed and the phone rebooted, into a bootloop. Its all it does now. When I plug in the charger, the phone turns on right away and goes to boot looping. I never get a light on, on the power button. When the sony ericsson appears on the screen, and I have it plugged into the PC USB, I get a mounted drive, until it reboots again. Sometimes when it boots/reboots it vibrates, most of the time it does not vibrate when it boots/reboots. Trying to boot to CWM, holding or tapping back/vol down/search, but from what I understand is I don't really have a permanent version of CWM and can't unless I am unlocked.
I am an exclusive HTC user other than this device.
So I was going to try this flashtool http://androxyde.github.com/ program, but I don't think that will work unless erither A)boot the phone and install an app, or B)be unlocked
Is it possible to unlock the device, in its current state?
I am updating the Android SDK right now, but I do not think that flashboot is going to help either, unless I am unlocked.
Is there not some type of RUU(phone flash tool) for Sony devices like there is for HTC devices?
I hope I don't have to try and get a war rep. I have a custom Zagg full body and I really like it.
Any suggestions?
Thanks,
~thehoovie

Use Flashtool, and you'll be fine. Install stock 2.3.3. http://forum.xda-developers.com/showthread.php?t=1351299
And you have to pay $24 to unlock the phone.

I was going to try to get the http://www.sonymobile.com/global-en/software/phones/xperia-play/ update, but I was worried it might install some newer OS version and then I would not be able to root(w/o unlocking), I tried Flash Tool first before this and it worked! I did try a few ways to get into CWM, including xrecovery, but none worked. Maybe if I had a found a CWM image for use in Flash Tool, but I haven't yet.
I tried a few ways to fix this, but everything I tried before using the ftf wanted me to be booted into the system, with USB debugging on, and/or rooted, which I couldn't get booted.
I was having a bit of trouble learning where to get images for Flash Tool and what folders it wanted them in, my previous experience with HTC devices, and Samsung ODEN tool helped.
What ended up working was installing Flash Tool v 0.9.0.0 , then the C:\Flashtool\drivers , then dragging the R800x_3.0.1.E.0.88_Verizon.ftf to the main window. I followed the on screen instructions, with the device off, I held search (and didn't let go until the process ended), and plugged in via USB.
Now working to root and remove bloat!
I am still going to unlock, I think it is a good idea to do so anyway.
Thanks again!

[Q] [SOLVED] Tried installing CM 10.1.0 RC5 Odin now the screens just black

Well, after a series of rooting and trying to get CWM recovery on my Xperia ZL and getting SuperSU I decided it was time to update to CM 10.1.0 RC5 Odin I didn't unlock my bootloader cause I don't know how, to my knowledge of a video I saw online if your phone says that you cannot unlock your bootloader than you can't. So I just thought it was okay to install CM 10.1.0 and did so, now my phone is stuck in infinite reboot without any sort of logo and just stuck at a black screen. I was wondering if any of you guys can help me solve this :\ thanks!

If you can still access CWM Recovery you can try to restore a backup of your old system. Otherwise you will have to flash an FTF using Flashtools.
(You can find the FTF that belongs to your phone here: http://forum.xda-developers.com/forumdisplay.php?f=2094).
If it is your first time using Flashtools you can search here in xda for guides, there are many that explain how to flash a FTF
And, as I said in another post before, every rom that needs to flash a Kernel (CM10.1, PAC, ReVolt, etc) you must have an unlocked bootloader unless it's tagged as a stock based rom.

I love you so much man, thanks a lot. I'm going to try out a couple of methods to at least restore the phone to 4.1.2. Do you have any advice on how to unlock the bootloader or any roms that doesn't require an unlocked bootloader?
Edit: By the way, I can't access CWM I wish I could, but I tried pressing the hard OFF button on the back of the phone and I tried pressing every button as well, it doesn't connect to my laptop or computer at all. Any way I can connect it to reset it?

Actually all Stock Roms (Found here: http://forum.xda-developers.com/forumdisplay.php?f=2094) don't require an unlocked bootloader, but if you want to unlock it so you can install Custom Roms (Found here: http://forum.xda-developers.com/forumdisplay.php?f=2095) that are not Stock based here is a very nice Tutorial about how to do the Unlock Bootloader procedure: http://forum.xda-developers.com/showthread.php?t=2153261

You are the boss man, thanks a bunch I was so worried about my phone. I just got it and was about to unlock it for a company that's super cheaper than all the other phone companies. I'm currently flashbooting it so I can restore it. I will take a peak at the bootloader unlocking procedure and I'm going to thank you again for your help.
Edit: My phone is being recognized in Flashmode only and randomly disconnects and reconnects. I hope I can flash it when the .zip is done downloading. I'll keep you posted.
Edit 2: I'm stuck on FlashTools "Reading Device Information" :\ now I'm stuck at 7% of Flashing Data and it hasn't moved

I would recommend you to flash this FTF first because you need to recover your android system first so you can move files in and out, install recoveries, etc. After doing so you can continue with that rom

Do a hard reset on it (using the button on the back), don't turn it on and follow the Flashtools flashing process
1.- Open Flashtools
2.- Flash mode > Flashmode > Select the FTF you just downloaded (The one of 700+MB) > Flash
3.- Connect your Phone if Flash mode (It will start flashing).
4.- Boot your phone and you're ready to go.
When selecting the FTF just select it and leave everything as it is and make sure that you have installed the drivers for flashing (
They are where found you installed Flashtools
In a folder called Drivers, open the .exe and Install these:
- Fastboot drivers
- Flashmode drivers
- Xperia Z and SO-02E drivers
If stills doesn't works I can't help any far as that, but I would suggest you that If you are able try to flash it on another computer (It might sound silly but It could actually work ), also make sure that you're running the latest Flashtool which is v0.9.11.0 and can be found here: http://androxyde.github.io/

Alright perfect, thanks again for all the help! I'm going to try the flash and I'll be back to hopefully say it worked !
I finished flashing it, once I did it told me to unplug my phone and turn it on. It still hasn't turned on but the light has started actually flashing and staying on now compared to before. Hmmmm...
Edit: Nevermind I got it, thank you so much!!! I'm so happy!

Xperia arc S Ultimate HD 3.0.1 HARD BRICK WON'T BOOT WON'T CONNECT

Hello everyone. I know that before I should create a thread I should search the site more to see if there are similar threads. I have but unfortunately I've only found a few with no solutions.
This is about my phone which I flashed Ultimate HD 3.0.2 last June(mid). Everything was going well. I didn't have to restart my phone as much as when I had cyanogenmod. Last Sunday while trying to take a photo my phone died because of low battery. When I got home I charged it but would only get stuck at the Sony logo. To sum it up.
- When turned on/charged, the arc s would only get stuck at the Sony logo(no red LED light). The screen would get brighter, then dimmer, then blank, then go back to the Sony logo. I 'd gladly boot to CWM but nothing happens no matter what button I press. (Maybe I'm doing it wrong? No one clearly knows how to boot into bloody CWM. Almost everyone seems to say, errrr keep pressing back/menu/volume down/power after the Sony logo appears. If someone could clear it up on how to really boot into CWM, that would be great thanks)
- Tried Flashtool, PC companion, SEUS, but the phone also seems to have connectivity problems with the pc. It would slightly detect it then disconnect again. I try to flash a different kernel using Flashtool, the phone's LED turns blue(clearly indicating that it's in fastboot mode), but when I select a kernel, flashtool claims that I have to be in fastboot mode even when my phone's LED is blue.
I can't use any of the 3 tools(SEUS, PC, Flashtool) because it can't even be detected by the pc.(BTW I've fully charged the battery using an independent charger)
I fear this is a hardware problem but I hope it can be fixed. I'd really appreciate help. I've missed college to fix my phone just like I have before but this one won't budge. Thanks.

To OP: Does the phone go into flashmode or fastboot mode? Do you have the drivers installed properly?

From my experience, if you install CWM on a rooted phone but with a locked bootloader it uninstalls as soon as you flash a new ROM and you have to reinstall CWM over again every time you do so.

Not exactly uninstall, the CWM for locked bootloader is installed on /system partition. This partition is wiped every time a new ROM is flashed, therefore removing CWM from your phone.

Some (if not most) ROMs, which are available for locked bootloaders, also include recovery already on the /system partition. At least I have seen custom recovery files listed in AROMA installation files for locked bootloader options.
I have not tested it myself (the freedom of unlocked bootloader ), so I am not sure though

Boot it holding the volume up button. This should get you into so-called "recovery" where you can, among other things, restore it to defaults.
If recovery also doesn't work (which would be unusual), boot it holding volume DOWN button. This will get you into a "download" mode where you can use ODIN to flash new recovery (such as CWM recovery which is very nice and powerful), or even flash entire firmware from scratch.
Good luck, let us know how it goes ~
[edit] oh and do all that while having it connected to USB power, in case the battery is empty.

still doesnt work

Anything doesn't work , When I boot while holding HOME and volume up (recovery) appears the blue advice in the upper left corner and about 2 segs after the cellphone restart again, again and so on, When I boot with the down (download) the process on kies working good but when ends the cellphone restart again, again and so on. I'm start to think that something in the hardware is damage :crying:

looks like you messed something up there...
Anyway, if your phone is rooted, and/or you don't care about warranty you can get it in download mode (you said it works fine with kies until reset, so I suppose it means that download mode is at least accessible).
And after that use Odin to reinstall the stock rom completely.
Or, again with Odin install custom recovery, and then whatever ROM you like.
While working with odin, be sure to stick to the guides here on XDA. (for a custom recovery see: http://forum.xda-developers.com/showthread.php?t=2364980)

If you're not entirely stock you'll have trouble using Kies.
I myself had trouble when tried to revert to stock ROM from CM.
It failed to restore NANDroid backup every time, and I also didn't succeed in flashing the stock image with Odin as well.
In the end, I succeeded with this ROM (which is modified stock TW), usin ODIN. You can try this, just read and understand the instructions in the thread before you do anything.
Ironically, after a couple of days after reverting to stock rom I was so annoyed by the speed decrease compared to CM, that I reinstalled CyanogenMod back, found TouchWiz stuff I missed via separate apps, and I'm pretty happy with it ever since.
Bottom Line: anyways, if you already on custom stuff with altered warranty, you must get custom recovery working first, then it will be simple.

[Q] flashed tmo on att d850 HELP!

I just flashed a rom on my d850 and now the screen wont turn on the phone is completely unresponsive I don't know what to do I can't even get the phone to boot some one help me im sure I just bricked the phone..

First, what rom did you flash and how did you flash it?
Try this as well:
Pull the battery, press the power button for a few seconds. Put the battery back in and press the power button again. Pop the battery out a 2nd time and then put it back in. See if it turns on.
If that doesn't work, pull the battery and hook the phone up (without the battery) to a computer and again see if it turns on and shows up in device manager.
Flashing the wrong rom should only result in a non-booting situation. If you have a custom recovery installed, you should be able to still get into that. The d850 has some serious issues with successfully rebooting in general (which can be resolved by the two suggested procedures above), so I would suspect that before worrying about a brick.
Lastly, the d850 requires bumped ROMs to get by the locked bootloader. The d851 (T-Mobile version) does not have a locked bootloader, so the roms are not bumped and will of course fail to boot.
Once you get back into recovery, just wipe all partitions except for internal storage/sd card and install a correct rom.

When you say you got the phone on, what do you mean?
If it is on and showing up as a phone in Windows, why not just use the LG recovery tool and flash back to stock, then start over?

Give the lg firmware flash and recovery tools a go then. There are several threads on here dealing with unbricking phones that detail what you need to do.
