[Q]Flashmode with Xperia Play 800a

Hi, I was wondering if my phone is capable of entering flash mode.
I have a Xperia Play 800a phone, from Rogers
Additional Info:
Tried Gingerbreak initially to root, not knowing it wouldn't work
Moved on to FlashTools, to attempt flashmode
Then to Root MANY ANDROID! [Upd: 20.09.2012].
Afterwards, I think the option to root (zergRush) using Flashtools got enabled, clicked that, phone got rooted
Busy Box v1.19.0 installed
Android version: 2.3.4
Build number: 4.0.2.A.0.42
Baseband: -56
Kernel: 2.6.32.9.-perf
Root Access Allowed
Using FlashTools:
I've read multiple threads of how to get into flash mode (Unplug your device, power off the device, hold back button or home button (also tried pressing button consistently), I've tried pretty much every button, and then plugged in the USB cable. I even took my battery out for 5-10 seconds, still no luck.
Once I plug my USB cable back in to my phone, while still holding back button or search button, the Sony Ericsson screen pops up, I get a dundun sound from the PC, then my light turns green and the phone begins charging, no flashing/action from FlashTools begins.
This is the message I received from FlashTools
28/022/2012 17:22:09 - INFO - Device disconnected
28/027/2012 17:27:36 - INFO - Device connected with USB debugging off
28/027/2012 17:27:36 - INFO - For 2011 devices line, be sure you are not in MTP mode
Another method I attempted was going into SDK tools folder, opening cmd in the platforms-tools, using the command "adb reboot-bootloader" and it just restarts my phone normally.
fastboot commands don't work either
I've checked my phone to make sure I'm in Mass storage mode, and USB Debugging is enabled.
I visited this site as well http://unlockbootloader.sonymobile.com/instructions
Entered this number into my phone

Could this possibly mean phone isn't able to enter flashmode?

Im assuming you have the xperia play drivers installed. You can enter flashmode but you cant enter fastboot mode thats disabled because your bootloader is locked. To enter flashmode power off your xperia play (without removing the battery). As soon as your xperia play is off press and hold the back button and connect the usb cable to the pc before the xperia play boots up. If you look at the power button it should have the color green=flashmode thats what you should be looking for. Blue is fastboot mode these are indicators what mode your xperia play is in. You need green for flashmode.

When you say Xperia play drivers, what exactly are you referring to?
And yes I do follow those steps of turning off the phone, and holding the back button, and plugging the USB cable. The light still stays green, no matter what I do.
Maybe I'm missing those Xperia play drivers?

[Q] Nexus 7v 2 Bootloader cannot be unlocked

Yesterday, I have tired several time, several tools to unlock my N7v2 bootloader. However, they all freezed on UNLOCK BOOTLOADER option on my device. (The process stucked after I pressed "Yes" and cannot go back to fastboot:crying. So I guess there's a problem with my bootloader, right? Please help me

Does your tablet reboot into bootloader?
If so just go in your adb directory and type
fastboot oem unlock

And do note that after pressing yes the device wipes all data and reboots itself. This can take 5-10 minutes.

I did what you said and typed fastboot oem unlock in cmd, then, the device rebooted into bootloader and unlock bootloader screen, but the failure was shown on cmd (unknown error, code error or something), then the device freezed on Yes&No in unlock bootloader. It's really strange.

After it fails and you reboot, is the BL still locked at this point or is it unlocked already? Perhaps, it is already unlocked and you may just need to factory reset to get the device to fully boot up.
The little lock symbol on the boot screen will show a small break if the BL is unlocked.

What does "reinstalled bootloader interface" mean anyhow? You flash the bootloader again onto the device from the factory image? Or did you have to reinstall something on your computer (ie. drivers, etc...)?
Would be helpful to clarify for anyone who hits this thread in the future.

It means I reinstalled bootloader interface driver on PC while the device was stucking on UNLOCK BOOTLOADER option screen.(after selected Yes). It suddenly turned into fastboot screen and continued to finish rest of processes. I hope this would be helpful for people who hits this thread. Make sure your USB drivers are installed correctly , because they seem installed correctly but actually not. If you got stuck on UNLOCK BOOTLOADER screen, try to reinstall it or install another usb driver..

Just wanted to say that this worked for me too!
I would get to the point where I would have to pick 'Yes' on the Nexus 7 screen using the volume buttons, and then when I would press the power button to confirm, it would just freeze. The volume buttons would not respond and I had to hard reboot by holding down the power button.
I just tried jianada520's method of getting to the 'freeze' point, and then I did this:
-Keep the tablet plugged in
-Open Device Manager and right click > uninstall the Android ADB interface and remove the driver
-Install the Driver (I used the Nexus Root Toolkit and installed/repaired the Universal Driver)
-Back on the Device Manager - Scan for hardware Changes
-Nexus should be detected and some kind of driver is installed
At this point the screen went back to the Bootloader menu automatically, but it now says 'LOCK STATE - unlocked', success!
Just thought I'd add my experience as this was sending me in circles for the past 2 hours of rebooting, reinstalling drivers etc.

How to remove BootLoader unlocked notification from boot screen

Hey all. I'm in a bit of a pickle. My Tmobile LG g4 has stopped fast charging. When I plug in any cable, I do NOT get the USB notification which allows me to connect to my PC. Enabling the MTP option in the Dev options still does not allow the device to be connected to the PC to flash back to stock for warranty support.
Is there any way for me to save something to the SD card to reset back to stock? Do I have to connect it back to stock or at least relock the boot loader?
I've tried multiple PC's and multiple cables with no success to get the device connected. When connecting to a PC, I get. The device has malfuntioned on my machine.

does it go into download mode.? phone off vol up key and connect usb.?
if you want to remove unlocked bootloader follow this comands
UPDATE:
I was able to Lock the bootloader.
1. I connected the phone to my PC
2. Powered on the Phone (it took a few tried of pulling the battery and powering on)
3. Check the box for OEM Unlock in Dev. Option
4. Use Minimal ADB and Fastboot and type in
Quote:
adb devicecs
- you should see the phone listed as one of the devices in the command line window
Quote:
adb reboot bootloader
- phone should reboot and you shouold see 3 lines of text on top
Quote:
fastboot oem lock
- nothing will happen on the phone, but on in the commandline it should say that it is done
Quote:
fastboot reboot
Phone reboots and the boot screen does not show the unlocked bootloader message anymore

Unfortunately, the computer will NOT detect the phone. No computer will. Using a USB cable that came with it , no luck either. Any ideas?

so basically theres no comunication with phone. not really. unless you go and exhcnage it to tmobile, so you cant remove bootloader unlocked message either. if you lucky and tmobile doesnt check for it then you may be able to get it exchanged. as it not recognized in any computer ill say its hardware problem. good luck.

Question Download mode issue

Hi everyone. Ive got my first samsung smartphone. I followed guides to get root, but unfortunately I had no oem unlock button in settings, I used date tweak, and button appeared, until I closed settings window. However in download mode, I still dont have any option to unlock bootloader, only use vol+ to enter download mode, or vol- to reboot. I ve tried to unlock it from adb, but no luck I just get my phone restart while trying to acces fast boot with adb reboot bootloader. Please help, phone is cool, and I dont want to refund

If the oem unlock isn't in the settings app you can't root it.

Go to Download mode like this :
Turn off the phone
Hold volume + and - and then plug in a USB cable ( already connected to a PC )
Then you should see that "unlock bootloader" option

Bootloading Kyocera DuraXV Extreme

Hello, I'm having some serious trouble bootloading my Kyocera DuraXV Extreme (AOSP)
I've went into developer options and activated USB debugging and allowed OEM unlocking.
But I get stuck on rebooting into bootloader mode. I've tried different approaches:
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".
2. adb reboot bootloader command
Both options reboot the phone without going into bootloader mode.
Seems Kyocera decided to somehow lock the bootloader mode. Anyone know of a workaround here?

My comments below are based on the belief that you are trying to unlock the bootloader.
I am not familiar with this phone but generally the two steps mentioned by you are not enough to unlock the bootloader. After those steps, you'll have to issue a command via adb to unlock the bootloader and if successful, then you can boot into it for further operations. The command will vary between devices, so search and profit.

Thanks, this cleared it up a bit, you are right, I'm trying to unlock it.
I'm trying the command fastboot flashing unlock but only getting the message < waiting for any device >. I read somewhere that I might need some USB drivers but I don't know where to find them. I have the latest version of the standard USB drivers for the phone, but as I understand it I need special drivers for this?

I'm trying to follow the steps here: https://www.ifixit.com/Guide/How+to+unlock+the+bootloader+of+an+Android+Phone/152629#s317298
I get stuck on the step:
Enter the command adb reboot bootloader
Wait a couple seconds until your device rebooted into the bootloader, then enter the command fastboot flashing unlock
My phone isn't "rebooted into the bootloader", it just reboots. It gives the message "< waiting for any device >" when I write fastboot flashing unlock

It should be a driver issue. When the phone is on and you connect it to the PC/laptop and send the command 'adb devices', does it show an alphanumeric value? Likewise, when you are booted into the bootloader by key combination and send the command, 'fastboot devices', does it show the same alphanumeric response? If so, the drivers are installed properly. If not, either you don't have the correct drivers or they are not installed properly. Try installing the drivers again after disabling driver signing in Windows on your PC (search for it on Google).

Hello, can you clarify what you mean by "booted into the bootloader by key combination"?
My problem is I cannot boot into bootloader at all.
Any attempt at doing so results in a normal boot of the device.

Are you sure that the key combination for booting into bootloader is what you described in the first post?
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".

I see Power plus Volume Up as the suggested one from a Google search. Try that.
If you can't even boot into the bootloader with the correct key combination, I don't know how to help you further since we are starting to go in circles. I am sorry.

Hello, thank you so much for trying to help me. It seems I can't boot into bootloader. Volume up + power gives the same result as what I did before.: It opens a "Recovery" menu where I can choose reboot to bootloader, but this option just reboots the phone.
I've been in contact with Kyocera and they say:
Thanks for contacting the Kyocera Customer Support. We will be more than happy to assist you with your concern
In this case allow us to inform you that since this device is a basic phone , it doesn't have the option to activate fastboot mode. By installing something that will change the way the phone works , that will void the warranty that came with the phone. We as manufacture can not help you to modify the software that came with the phone.
So the phone's fastboot mode has been deactivated. But since it's an android I guess it should still be possible with some workaround. I just don't know whee to start, I've been researching for a week with no result.

Something interesting ehre, maybe someone with more coding knowledge can tell what's going on.
I found the source code for the phone and located a file called recovery.c which I guess handles the menu I see when I press volume up + power button. Maybe some clue to why the phone isn't going into fastboot mode?
