[Q] Possible Bricked R800i

I very recently asked for help installing CM7 onto my phone. While following a fairly simple tutorial linked to me by the author something hasn't worked and I've been left with a brick. I managed to fastboot the boot.img then when rebooting I was asked to "spam" the volume button repeatedly until it entered another mode. It did not do this. Instead it simply left me with a blank screen. No Sony Ericsson logo and no booting into another mode as the tutorial described. Someone in the thread had the same issue and basically the author just washed his hands of it and asked that guy to make a thread. I did look at the troubled users profile for said thread but for some reason this forum is saying the search is down, so hopefully someone can help me at least get my phone working. I'm done with the rooting/romming shenanigans. If there is a way to just get my phone up and running then hopefully someone can tell me. Until then it's just a brick.
Edit - Tried updating via SEUS but it says the phone has modified software and cant be updated. :-(
Would flashtool work?? I have no idea how to use it tho but am downloading it. Looking for things on here is hard work. lol.

Is your boot loader unlocked? You didn't mention if it was or not. If its not then that's why your bricked.

Its unlocked. The tutorial before the one I mentioned above was about finding out if it was or not and it had a YES next to it in the menu. Along with my IMEI number etc, so I was told I was OK to go ahead with the other tutorial.

Flashtool Guide
Oh rght this should help you, okay. The answer to your question is yes flashtool should work, it sounds like you've got a botched install that's all if you doo this you should be fine
THIS WILL ERASE ALL DATA ON YOUR PHONE BUT NOT YOUR SD CARD
Here's a quick rundown of what you need to do, Download flashtool, download an ftf file, flash the ftf file to your phone through flashtool and then as if by magic your phone should work. So let's begin
Step 1) Turn your phone off - Then leave it to the side.
Step 2) Download and install Flashtool Get flashtool from here
After it has downloaded install it but make sure you have remembered the directory where you've installed it.
Step 3) Download an ftf file. This is a package that contains the stock software that came with your phone and flashing this will therefore return your phone to factory settings or stock.
Here is a thread with a list of ftf files, download the one that corresponds with your phone.
After you've downloaded it move it the folder named firmwares in your flashtool directory. For example mine is C:\Flashtool\firmwares
Step 4) Install the drivers. Navigate to the drivers folder in your flashtool directory, for example mine is C:\Flashtool\drivers From there open the file named Flashtool-drivers.exe and install ALL of the drivers.
Step 5) Flashing the FTF. Once you have installed all of the drivers open flashtool. From there click on the flash icon in the top left corner of the screen. Select Flashmode then click OK.
Select the FTF file you downloaded and moved to the firmwares folder and then click OK.
You will then see flashtool say it is preparing files for flashing follwed by a popup. The popup will promt you to power off your phone, hold the back button, then plug the USB into your Computer.
After you have done this flashtool will begin flashing your phone. Do not remove the USB until it is finished.
Once it has finished (The log will tell you when it has) remove the USB and power on your phone.
The initial boot may take some time as needs to rebuild it's cache. Don't panic this is normal. After it has your phone shoudl now have booted and be on the stock software that came with it
Hope I helped, if you need anymore help PM me

Thanks for the help but I was just too over that phone so I sent it away for cash (even fuc*ed it was worth £32) and I've got a brand new Xperia Arc S. Thanks.

[ROM][ARC/S]JELLY SANDWICH 4.5[09.09] Sonys logo problen

Well people, I have some problens on my Xperia Arc S GSM
The problem is the rom don't out Sony's logo
I found a Answer to me Question but I don't know how to fallow him
"locked bootlaoder ?
If so you need to flash an official ICS rom with flashtool, root it again, and reinstall x-parts.
Now you should be able to enter cwm.
Then do the full wipe and format system, and flash 4.4 Jelly sandwich.
Always remember that x-parts installs a recovery in the /system folder, not in the kernel (as it is on unlocked bootloaders), so if your rom is messed up, you can't access the recovery anymore and need to reinstall x-parts again, and for this to be done, you need to flash an official rom with flashtool first then root it."
How to Flash Official ICS on flashtool ?
Please, I live in a 3 world country called Brazil, when this phone cost about US$ 700 ! and the minium wage is US$ 350
And if my father discover that I in dead!
Please, I just want to bring my phone back to life
Please HELP ME!
Sorry for my poor English, Brazilian...
:crying::crying::crying:

Try
Use sony update service to repair the phone or flash a generic ROM.
For flashing ROM:
1. You need latest flashtool. Get from here http://androxyde.github.com/Flashtool/
2. ROM (in .ftf format) - Download the ROM that you need.(Search in xda forum)
The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. Do this only if you’re capable of getting your phone back right on your own. If any damage occurs to you or your device, we won’t be held liable. You only will be responsible — you’ve been warned. Okay!
This process will clear all user data and applications.(contacts, messages, call data, apps, apps data etc.,) . Please take backup of all your data before you start.
Instructions:
1. Switch off your phone and put it aside.
2. Extract the “FlashTool_x.x.x.x.exe” file on your PC (you can just double click on it to extract)
3. Few files and folders will be extracted — the two which we’ll be using are the ‘drivers‘ folder and the ‘firmwares‘ folder.
4. Inside the ‘drivers‘ folder there’s a file named “ggsetup-2.2.0.10.exe”, double click on this file to install the proper driver on your PC.
5. Now copy the “.ftf” firmware file that you downloaded for your phone, and paste it inside the “firmwares” folder.
6. Double click the “X10FlashTool.exe” file.
7. Once the program opens — click on the “Flash” button.
8. You’ll see the firmware that you copied in Step 5 loaded on the screen — click “Ok”!
9. Now it should ask you to connect your phone to the PC. So first plug the USB cable to PC, then pick up your phone and hold the “Back” key (key at the bottom left on
your Arc), and then connect the USB cable to your phone. Remember you’ve to hold the “Back” key while connecting the USB cable to phone.
10. Once the phone gets connected — Flashtool will automatically start the flashing process.
11. Keep an eye on the Flashtool’s screen.
12. And once the process gets finished, disconnect your phone from PC and switch it ON.
13. Don’t freak if it takes longer to boot (that’s normal) as the phone has to build the cache again after flashing.
Enjoy!!!
Hit "Thanks" if anyone helped you. :good:

[Guide] Motorola Defy Mini XT320 Root

So coming from this :
http://forum.xda-developers.com/showthread.php?t=1658568&page=38
Thread i decided to create a new one to collect and focus all necessary informations for the procedure of flashing and rooting the Motorola Defy Mini XT 320.
Credits for Rooting Guide and files goe's to leos0 and i thank him very much for giving us (me) the freedom to root this Phone.
Also many thanks to coder011 he extracted the recovery.img from defy mini which is necessary for rooting :highfive:
Table of Contents:
Do i have Fastboot or not?
How to flash Firmware?
How to gain Root access?
Which Firmwareverisions have Fastboot Mode?
How to flash only older Bootloader to get Fastboot without changing Firmware?
At first, you have to know if your Phone have Fastboot or not.
The easyest Way to find out, is to boot the Phone in Recovery or (if it can) in Fastboot Mode.
Power off the Phone
Power on by pressing both Volume Buttons and the Power Button at once and hold them for 5-10 seconds
if then a screen comes up, you can see if you have Fastboot
look at the pictures below to compare
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
If you see this, then you are a happy one, because your phone has fastboot. You can directly go to the rooting procedure below. :good:
If you get this screen, you have to decide if you want to risk an flash of different SBF Firmware file as described in the next Part of Guide.
Your Phone has no Fastboot. :crying:
Due to some questions in this Thread i want to make clear, what is necessary to do all this strange stuff.

I read the guide. The only mention of installing drivers is in the flashing guide and that guide is for users who didn't have fastboot on their phone.

OK
For anyone who needs it more clear.
For everything that is more than using the Phone as USB Mass Storage, you need to install the Drivers.
What the PC doesn't know, he cannot deal with it.
Drivers are (nearly in everything you do) absolutely mandatory.
And if anything doesn't work on a computer, the first thing you be asked is "Have you installed the drivers?".
Defy Drivers:
http://www.motorola.com/consumers/v/index.jsp?vgnextoid=2cff07f8ef573210VgnVCM1000008806b00aRCRD
Install the Drivers and connect your Phone with USB Debugging enabled or bootet in Fastboot Mode (Power up with holding Volume + and - Buttons for 5-10 seconds).
If the Drivers are installed correct your Phone was shown in device Manager like this:
For flashing other Firmware your Phone must connected as Flashing device.
Power it up with Volume - and Camera Button pressed. You see then an Black screen with some white Text.
Connect Phone and let Drivers install.
If your Phone is connected correct it will be schown in Device Manager like this:
Only after you have installed all drivers and your Phone is recognized by your PC as shown above, you will be able to work with ADB or RSD-Lite.
At first, my Guide to flash your Phone with different ROM if your ROM didn't have Fastboot.
Flashing Guide:
And you have to download RSD Lite:
http://www.chip.de/downloads/RSD-Lite_49139659.html
Defy Drivers:
http://www.motorola.com/consumers/v/index.jsp?vgnextoid=2cff07f8ef573210VgnVCM1000008806b00aRCRD
Install Drivers and RSD-Lite.
Start RSD Lite and load SBF File.
Then shut down the Phone and Boot up by holding Camera + Volume- (down) and Power Buttons.
If you done right, you see an black screen with white Text, telling you the Device is in flashing mode.
Connect Phone to PC and let Drivers install (after that RSD Lite shows an "Connected" Message in App.
Click on "Start" in RSD-Lite
Flash begins and you see a lot of Message Lines for everey Flash Step.
At the End of the Process Phone reboots.
Now you cann deconnect and close RSD Lite, ignoring the Message that it is still in Progress.
BUT NOT BEFORE THE PHONE REBOOTS!!
Sometime there is an Error and the Flash fails at first try.
You have then to pull the Accu and to repeat flash Procedure.
Warning!!!
You can brick your Phone!!
In some cases the Phone loses IMEI and Connection to SIM and is broken!!
If you do this, you do it at your own risk!
To prevent this and/or to recover your IMEI and unlocked SIM follow this Guide:
[Important] Backup and Restore Defy Mini IMEI and NV Data
Additional Hint.......
If you can't find an ROM of your native carrier which is rootable, search for a ROM of an Carrier from your Continent which supports eventually your Language and Carrier.
E.g. i found Brazil ROM which is rootable but have no German Input and Language. So i testet some European ROM's and found one from Spain which is rootable and have native German Support and APN in it.
So now i don't need to test further because all works great and have German Phone UI.
The ROM i use at the Moment:
http://hotfile.com/dl/184330128/2d4ce8b/TNBST_4_0A.1F.0ERPS_flex_WE_Orange_Spain.zip.html
(you have to register before you can download, ZIP Password is "mod2xtreme.com" but be aware, that the Site is sometimes down)
And feel free to donate to the Board for their excellent Service to offer us this ROM's. :good:
If you have an ROM with Fastboot, follow this Guide to Root (Original Post from leos0 here):
Important!!
Some prerequisits:
Download and extract the View attachment root_xt320.zip to the Root of your Harddisc. Best place is C: so it has to be in
Code:
C:\root_xt320
.
If you place it in any other place, adjust the Path variables from next advices to your needs.
Open Command prompt on PC.
Type in
Code:
cd C:\root_xt320
and hit Enter
Now you are in correct folder to do the next steps
Okey, so, rooting You have to download this : ( it contains fastboot adb recovery.img and update.zip [ I think it is the right one, becourse
i was applying a few of them at one time to save my time xd ] )
0. Copy update.zip to /sdcard/
1. You need to boot into fastboot (NOT RECOVERY, F A S T B O O T ). You can use:
a)
Code:
adb reboot-bootloader
or
b)turn off the phone, then hold POWER+VOL UP+VOL DOWN for 5-10 sec.
2. Now you need to use fastboot. use:
Code:
fastboot boot recovery.img
3.Now CWM TOUCH will boot. There is small problem, it doesn't look as it should, some options are somewhere else etc.
But it works! In normal CWM Recovery i was unable to choose any option, but there everything "works" And you should use
keys on your phone ( POWER to execute, vol. keys to move ), not screen to choose things ( it crashed once when i was using screen )
4. Install zip from sd..(second option)-->choose zip from sdc..)--> ...choose...--> Yes - Install --> Reboot --> back
For commands in [.code] marker you need to use cmd. I hope it will work for you guys You are doing everything on your own so if something dont work its not my fault.
If you want to repost it somewhere, please, just write who invented it You should also thanks coder011 becourse he extracted the recovery.img from defy mini which was very helpful
Enjoy

Rootable Firmware List

TNBST_4_0A.1D.22RPS_flex_WE_RTIT
TNBST_4_07.26.11RPD_flex_LATAM_RTL_Brazil
TNBST_4_0A.1F.10RPS_flex_WE_Retail_CEE

Some additional "special" Procedures to have mor Options
Option to flash only older Bootloader with Fastboot enabled without changing your current Firmware and have the Option to root after that.
Some "special" Method posted by Alin Razvan, member of droiddevelopers forum.
Let me explain how i got this working a good sbf flash with a lower bootloader version.
First step you are about to do, is downloading a compatible sbf version that you like !
2nd step flash it with RSD Lite 5.7
3rd step after flashing it go into recovery menu by pressing both volume keys + - and power up .
4th step -> Clean Cache -> Clean User Data , after cleaning select reboot
5th step Let it reboot normally , set it up , connection etc , google account and so on .
6th step Download TNBST_4_0A.1F.0ERPS_flex_WE_Orange_Spain.sbf
Power off the phone , remove battery , pres camera button + volume down+power insert usb (if doesn't power up attach battery but only for a second than remove it) , now you should be in boot mode .
Open RSD Lite 5.7 select the TNBST_4_0A.1F.0ERPS_flex_WE_Orange_Spain sbf file and (read bellow).
Here comes the tricky part !!!
Be carefull and fast otherwise you got to flash again your favorite sbf ,and follow the upper steps again !
Before pressing start button take your phone on your right hand , grab with your left hand the usb cable because you are about to pull it back quickly after you see
Flashing Modem (mdm) or something like i reallly don't remember how the text really was but what you need to do is let it flash some reboot files it takes up 3 seconds after pressing start button to flash those files so you got to be fast boot ) i know it sounds awkward but this **** really works !
After removing usb cable your phone will instantly shut down because it doesn't have the battery on , i did it without battery because i wanted the phone to shut down instant !
So the next step is to power up the phone by pressing both volume buttons + - and power up button , now you should see fastboot menu YaY!
After that, you can switch to the rooting Procedure as described above.

Alin's method consists of loading an older bootloader version. In theory you don't even have to flash an SBF if the one you're using (original or already flashed) is working for you (meaning no simlock). You just go from step 6 onwards.
You put the phone in flash mode by holding camera+vol down and powering the phone. You should see a screen with the following:
MBM Flash-mode.
TinBoost
version: 06.0a --> (versions may vary)
Bootloader USB Init SECURE BOOT ENABLED
Now you have to use an SBF with an old version of bootloader. I don't know up to which version the bootloader has fastboot, but I used the SBF TNBST_4_07.1D.20RPS_flex_LATAM_VIVO. This one has fastboot.
So, you open RSD Lite and use this SBF. When you click start first it will update (in this case downgrade) the bootloader version. It will run some stuff and then you will see the same screen from above again (but now with different version - 01.0a if you use the SBF I mentioned) and it will start the flashing process. That's when you have to unplug the battery or USB cable to stop the flashing. All you wanted was to install the bootloader.
After that you just have to follow the procedures as if your phone had fastboot since the beginnig! That was a very smart move by Alin.

I have tested Alin's Method today.
My biggest Problem was, that my Phone is not able to Power on only with USB Cable connected. I also have to insert Accu (very loose) and to pull Cable and shake out the Accu the same time immediately as the Message of "Modem flashing" (or something like this) comes up on Screen.
I now have newest German ROM ( TNBST_4_0A.21.0CRPS_flex_WE_RTDACH ) with Bootloader (Fastboot enabled) from Spanish ( TNBST_4_0A.1F.0ERPS_flex_WE_Orange_Spain ) ROM and rooted.
Great thing.
Big thanks to Alin and afadel for this!!

Moved to General

TNBST_4_0A.1D.22RPS_flex_WE_RTIT
This is the ROM my phone came with (Italian retail), it has fastboot and it's not sim locked.

Sorry Guy, have you read the above Guide?
This is exactely what i wrote.
But without all the Pull of Accu and USB and, and, and...
Because it is simply not necessary.
Flashing is much mor simple. Just two steps.
And why should anyone flash two times?
First with an SBF of his Wish. And then (by completely overwriting this Firmware in the Phone) with the one you posted?
And exactely this is also the one i used and wroted in my Guide.
But a lot of Asian and Latam Users cannot use this because it is not containig their Languages.
So this is why i asked anyone who have rooted his Phone to write here with which SBF he does it.

No bro, you do not flash 2 times.
First time you flash some sim unlocked firmware that works for you, than you flash the one with bootloader, but not the whole firmware, just modem stuff, and then you cancel the flashing by disconnecting the phone so you still have YOUR old firmware, but now it has new firmware's bootloader.
I hope i made it more clear now.

OK.
My fault.
I'm to tired to read conscious. Last 8 days in job was to busy.
Will give it a try.
But i am not sure if i will do it really, because i am very satisfied with my current state. I have installed the TNBST_4_0A.1F.0ERPS_flex_WE_Orange_Spain.sbf by flashing it completely and have set up Link2SD and all works like a charm with constantly mor than 120mb free internal Memory also after installing a lot of Apps. :highfive:
But.
If you agree, i will include your advice in "my" (not really mine, have only made a summary) Guide.

Sure, just write that the original creator of that method is Alin Razvan, member of droiddevelopers forum.

Congrats for the initiative!

[Q][Xperia Arc][LT15i] Clear threads on rooting and flashing custom ROMs?

Hi, I have a sister who uses Sony Ericsson Xperia Arc LT15i, Android 2.3.3, build version 2.6.32.9-perf, but I haven't tweaked with Sony Ericsson phones before so I don't know anything about her Arc's kernel and stuff.
She has problems with her device lately (lagging, response is slow etc.) and wants to root and flash it with a stable ROM, preferably as new and as fast. I tried helping her by finding threads on this forum, but there are too many stuff need looking through, and my eyes hurt just by looking at them builds and codes (too many broken links and complicated instructions).
Anyone can redirect me to a thread where it has clear and simple instructions as well as availability of downloads to links and software needed for the root/flash?

This is recalling from memory and the links that I have saved. I'm not going to go about doing searches to verify stuff for you, but the steps I've outlined below should sufficiently deal with the queries that you have.
A) Unlock the bootloader. Follow the instructions.
http://unlockbootloader.sonymobile.com/
B) Download and install Flashtool.
http://androxyde.github.com/index.html?1363797001000
C) Install the drivers in the "drivers" folder under the Flashtool installation directory (c:\flashtool). Tick the XPERIA Arc option, and tick Fastboot (should be at the end).
D) Download stock .587 ICS firmware. Place it into the "firmwares" folder in the Flashtool directory.
http://xperiadev.wordpress.com/flashtool/xperia-ftf-firmwares/
E) Download the following kernel. Place it into the "firmwares" folder in the Flashtool directory.
http://forum.xda-developers.com/showthread.php?t=1838916
F) Start Flashtool. Power off your phone. Keeping the "back" button (the first button from the left) pressed, connect your phone to your computer using a USB cable. Let the drivers install. Once your device shows up as connected in Flashtool, click the "Flash" icon, select Flashmode, and select the .587 firmware that you've downloaded. Wait till you get the message that the software's been flashed to your phone.
G) Start your phone. See if the firmware's been installed and everything is working fine. If so, power it off again. Then, keep the menu/shortcut button (the first from the right, whatever the hell it is called) pressed and connect your phone to the USB port of your computer. Let the drivers install. Once you get the message that your phone's been connected in Fastboot mode, click the "Flash" icon, select Fastboot, click "Select kernel to flash," select the kernel you've downloaded earlier, and let the software flash it to your phone.
H) Power up your phone, see if everything's working. If so, you're done and ready to flash some custom ROMs. The instructions on how to do that will be clearly outlined in the ROM's thread.
I) If the phone doesn't start, then congratulations! You have a brick and a very angry little sister. Better run and hide!

Hmmm..
The link in part D is not functioning. Any other links available to this?

Was working fine yesterday. Anyways, you can download the firmware from here:

[Q] Help unlocking bootloader, root and flash.

Hello guys, i have a xperia ZQ C6503 Brazil, i want to unlock the bootloader , install a recovery and a stable cyanogen mod , but the cyanogen installer shows the device is not supported ( they are not equal the ZL ? ) , i want a correct step-by-step for this things i want, i am confused with tons of topics with differents things..
So i want a how-to Unlocka bootloader, install a custom recovery, how to root, and how to install the cyanogen mod without the windows installer if possible. thanks.

ZQ it's exactly the same of ZL, I don't know why Brasil changed the name, I have a ZQ and installed the cyanogenmod 11 for ZL and everything works, don't worry about that. I can see you're a little insecure, so I suggest READING MORE TOPICS. And make sure that you're installing everything for xperia ZL (ODIN) and not for the Z (yuga) or Z1.

AFTER READING DOOMLORD'S TOPIC: IF it's not clear, you can read http://techglen.com/2013/11/28/install-android-4-4-kitkat-on-xperia-zl-with-cm-11/# and http://wiki.cyanogenmod.org/w/Install_CM_for_odin
Suggestion: Use flashtools to install the custom kernel (connect the phone in fastboot mode, click on the lightning, choose fastboot mode and choose install/flash custom kernel) it's way easier than using terminal.
After installing adb drivers, sony drivers, fastboot drivers, and etc ...
1) unlock bootloader
2) download the last cm11 nightly and google apps for android 4.4.2 (search on the cyanogen site)
3) on the phone: put the .zip on the root of sdcard ........... on the pc: extract the .zip on desktop (you're just gonna use boot.img)
4) shutdown the phone, plug the cable on the phone pressing VOLUME UP ( + ) , a blue led should appear
5) open flashtools, click on the lightning and choose fastboot mode, after choose install/flash custom kernel and choose the boot.img that you placed in the desktop
6) Unplug the cable and reboot the phone (or it'll reboot by itself) WHEN SONY LOGO APPEARS (A PINK LED WILL APPEAR, this is the phone telling you that you can press volume up (+) to open recovery), so, when the pink led appear push the volume up (+)
7) Now you're in clockworkmode recovery, wipe cache/data/dalvik, flash the rom, flash the gapps, flash the supersu.zip(if you want it rooted)
8) Reboot (it may take a while, up to 5 minutes)
9) Have fun
