achieve APX mode and other tricks adhoc

Since this model is new, i assume all facts are new too.
- SAFE mode is started by holding Vol+ and power button at the same time at startup.(adb shell is enabled, nothing is running(single user mode?)
- FIRMWARE upgrade mode seems to be Vol- with USB cable connected at power-on.
- APX mode is started by holding Vol+ and Vol- down at the same time at power up(when pressing power).
* since we do not have a bootloader.bin yet, it will be hard to try anything. can we use htc onex bootloader.bin?
* tegra3 is also locked with a SBK, which we do not have either (i believe).
-Battery mode
Turn off mobile. attach USB cable to pc and mobile. turn on mobile.
- adb reports shell not found and some root details?
im still digging into the fastboot mode, so information can be extracted on the rom rel. etc.. maybe someone already knows?
ill keep this updated, if i find out more.

APX drivers
Do you have APX drivers for 4X ?

not yet, i assume those for asus prime should work as well?

it not work.

@Dexter_nlb
I read that Asus will release NVFlash for Asus Prime.
Do you think it will also work for us?

I believe they for a fully working apx mode since prime got a full recovery using apx mode?

recovery details added.
thanks to 911rsr

Nothing happens. Nothing shows on screen. When i hook it to computer, it makes a noise that it found some device, and in device manager shows as APX, instead of as modem or anything else....

Bricked. APX mode only
Did you find how to fix it?. I have the same issue after a failed upgrade using LG mobile support tool.
No SW upgrade mode, no screen or leds activity, no nothing. When is connected to PC, APX device is recognized. I found some drivers and the APX device is displayed now as "NVIDIA USB Boot-recovery driver for mobile devices". I'm stuck there. I was looking into NVflash utility but after the command "nvflash --sync" only get "unknow device found"
Can anybody help me please?.
How can I get into SW recovery mode or something that shows some activity from the phone?.
Thanks and regards

i guess not much can be done. sent mine to the service center and got it back 3 days later fully functional. i guess it's easier to restore for LG since they have all the tools and magic keys.

Hello!
just happened to me.
apx mode you solved anything?
one can solve?
Thank you!

NVflash doesn't work, at least after upgrade to JB.
Before give your devices as bricked, try to enter in S/W without battery a few times and after with battery on.
Sometimes stressing the device have some results.
But the best you can do is take it to service.

Thanks gingerboy92. I follow your advice and my phone is in a LG service center now. Hope they can fix it.
I think that's the only safe way to recover it. Looks like Tegra 3 devices have security keys that are unique for each processor and without them you can't go further.
Amigo ruedaslocas, I tried many times to do what you say, unsuccessfully. Thanks anyway.

[Q] Xperia T LT30at is stuck at Sony screen.[SOLVED]

The problem.
When I boot the device it just stays at the Sony screen and does not progress any further. I am still able to turn off the device by holding the power button and the volume up button, I can reset it by holding the button longer waiting for the vibration, and I can hard reset by waiting till the three vibrations.
What I was doing up to the point it happened.
I was trying to get a custom ROM on my device, I had it previously rooted so I thought I would go further. I installed CWM on my phone I wiped data, cache, and dalvick then I went to install the ROM from SD card. During the attempt at installation I got some symlink errors with a status of 7. Not sure what to do turned off the device when I decided to put back its previous I turned it back on and arrived at the problem.
What I have done to try and fix it.
I have done the soft and hard resets, I tried using the PC companions repair tool. When it asks me to turn the device off hold down the power button then plug in the device nothing happens(I have tried this several times.) I downloaded the flashtool and the correct ftf and tried using that, but it doesn't detect my device when I hold down the volume button and plug it in. So it seems that the flashboot is not working on my phone.
Any suggestions on what to try would be much appreciated and thanks in advanced.

You probably didn't install the ADB drivers. Install them from the Flashtool folder (use the ones for TX) and then try flashing your stock FTF again. Remember to put the device into Flashmode.
Basically what happened was that while flashing your ROM the script that flashes everything deletes everything from the /system partition, then you got an error and the installation was incomplete, therefore there is no proper system to boot into. You could have easily avoided what happened by flashing a different ROM had you not powered off.

Thank you for response, I went and used the Flashtool-driver.exe and installed the Flashmode drivers, Fastboot drivers and the TX drivers. But it does not seem to have changed anything. To enter flash mode on the phone one has to hold down the volume down button while plugging the phone into the usb when it is powered off, right? Flash tool just sits at the instruction animation titled Wait for Flashmode. When I try to enter flashmode I do not get a response from either the program or the phone. Any more suggestions would be welcomed.
Thank you for taking the time to help.

Yes, that is how you enter flashmode. Turn off phone, and keep volume down button pressed while you connect the USB cable; the LED light should turn on with a green light. If you're phone is not entering Flashmode, then you might have a faulty USB cable, or there might be problems with your USB ports, either on your computer or your phone (try with different cables/computers).
Also, check your Device Manager (while phone is connected) to make sure the drivers are properly installed. If you have Windows 8, you should have had to turn of Driver Signature Checking in order for the drivers to install properly.

Yeah I turned off the Driver signature checking on my computer when I did it. I'll go buy a new cable and try a friends windows 7 computer. Hopefully there is nothing wrong with the USB port in my phone. Thank you for your help I'll let you know how it goes.

Thank you everybody for your support. My phone is now working. After my phones battery died I was able to get it charging, when it had enough energy it booted itself to the Sony screen so I turned it off and grabbed my new micro USB cable and was able to get it into flash mode. Everything is now working great. I wish a special thanks to Antiga Prime for taking the time to help me.

Hello! My LG P880 was Cyannogen CM11 mod, but was a little slow. So I decided to downgrade it to CM 10 I lowered the phone settings, installed it, but when it restarted was giving infinite loop. Now the phone does not go into recovery mode, it is not recognized in the PC USB. When I put the usb cable in pc it tries to recognize but gives blue screen and the pc restarts. Already reinstalled the driver on the PC but not accomplish anything. Trying to install the original rom by LG flash tools but it does not recognize. I tried to get into recovery mode but nothing. Help please !!:crying::crying::crying:

Weird how your phone makes you get a blue screen of death.
Can you say what it writes in blue screen? And also try your luck on another PC.My sister's laptop could not recognize my phone no matter what I did.
Blue screen is most likely due to some broken software/hardware on your PC rather than a problem with your phone itself.So do try it on another PC.
Can you also say, how it doesn't go into recovery mode? When you hold vol - plus power, does it make the phone reboot, vibrating but still stuck on LG screen or does it not even vibrate?

don't worry, the problem is your PC not your phone
try this 2 fix your pc:
start CMD with administrator privilege -->
chkdsk /f /r -->press enter --> Y
restart the computer, if you lucky it will fix you pc and you will be able 2 fix your phone
(the fix/test take 1-2 hours, depending on how big your HD and if you have errors/bads ectors)
if you r not lucky, you probably have driver collision and it more tricky 2 explain how 2 fix.
anyway, if you in a hurry do it in another computer

its very strange that u got blue screens in both computers.....
the error code that u gave usually points that something wrong with mscorsvw.exe and/or NET framework.
i would recommend to update to the latest NET framework or even uninstall it and install it again.
Another good idea is 2 install the Android SDK (it installs a universal usb driver), this might help - ill try this before reinstalling NET frame.
i hope it helps...

Can't enter in flash mode

Hello to all,
I would like to install a custom ROM but unfortunately my phone doesn't want to enter in flash mode! Once switched off, I plug it to my computer while keeping vol down button pressed but instead of entering in flash mode, it displays the battery charging icon.
I hard reset the phone but the problem still remains. Any idea.
Thanks, have a nice day!

My guess is either the USB cable (did you use the OEM cable?) or the drivers (does windows recognize your phone?). Removing the SD card or first entering recovery were suggested earlier (http://forum.xda-developers.com/xperia-l/help/update-volume-connect-doesnt-t2613733). But more experiences Z3c owners may have better ideas...

Using flashtool:
Turn phone off completely.
Start flashtool, choose flashmode and choose which firmware you are going to use. Tick Exclude TA.. Click on flash.
It will start preparing the build and after a few seconds it will ask you to connect the phone.
Plug the phone in while holding volume down, as soon as flashtool starts doing something, you can let go.
If you don't know how to use flashtool then I urge caution, Sony's aren't like flashing a Samsung, it is actually possible to brick your phone with flashtool. There are lots of questions on 'how do I fix my phone?' in this Q&A thread from people who didn't read up on what they were doing.
Recommend you read bilboa1's great guide on what to do, starting with backing up your TA partition..

Thanks for your answers but I think the mini usb from my phone must be dead.
About Flashtool, I can't use it because I can't go into Flash mode! Moreover, my phone is not recognized by windows. I tried with several usb cables and computers when I plug it, I don't have any MTP or PTP choice, it can only charge..
On Windows 10, devices is not recognized and Window 7 see it as a 5880!
And I tried to remove SD and SIM cards..

If the USB lead was dead you wouldn't get the charging icon on your phone.
Have you installed the Sony drivers.
You also need to run exe in the Drivers folder within Flashtool, to make sure you have correct flashomde drivers available. Installing these drivers is very difficult in Windows 10 and it require restarting the machine in safe mode, and going into the advanced settings to disable driver signature checking, this how to video is for windows 8, but you'll get the idea
Have you installed ADB?
Sonys PC Companion should set you up with the correct connection to your PC

Have you tried other USB cables?

Yes, I've installed PC Companion, adb drivers but nothing appears when I use command "adb devices". I've also installed flashtools drivers but deactivating drivers signatures in Windows. But when I try to flash, flashtool ask me to turn my device in flash mode (switch off then volume down + power) but I can't do that.
I've tried several usb cables. Some are charging my devices, some are aren't but none of them allows me to data transfer!
I've also tried to force MTP or PTP usb transfer in developper option, it doesn't work more..

Do you have any warranty on your phone, you could be right that the usb socket is damaged somehow, but it's strange that you can still get a charge through it.
Your only chance at moving to a custom rom change is flashfire
This should let you flash a rom without recovery.
Edit: Flashmode is just holding down just - volume button, not volume+power
Obviously your chances of rescuing a failed install are going to almost zero without recovery and flashtool, so be very very careful about what you try and flash in flashfire. Read up completely that the rom you want to flash is going to work pushed on top of whatever you are running at the moment.

For anyone who might be interested, sometimes you have to try a USB 2.0 port or just a different port. I had the same problem while using a usb 3 port, switched to 2.0 worked like a charm.

Try to open the back of the phone and removing/unplugging the battery wait 5 seconds and then put it in again. Then try holding down the volume down button while you connect a usb cable.

[Q] Boot loop for no reason

I left my Lumia 928 charging on the wall for the night and first thing in the morning while taking it off I noticed it was stuck in a boot look at the "NOKIA" screen. Seems like bootloader got corrupted for no good reason.
I can make it start Flash mode though and also Mass Storage mode with WP Internals.
Is there some way I can restore boot other than flashing original firmware and losing all my data???
Any help attempt is appreciated

I have just got this problem on my lumia 730. I have used Windows Recovery Tools to repair my phone. connect your phone to your computer by a USB cable. open WRT, if it don't detect your phone, hit the button My phone was not detected, choose your your device family and press power button + volume down button until it detected. if this doesn't work, try it again or you can use Nokia Recovery Tools. Hope this work for you

Yes, I am probably going that way. Thing is I wanted to retrieve some data in the phone first. I managed to enter flash and mass-storage modes. But can only acces system files in mass-storage mode
