Hey everyone,
I have a cracked and blacked screen on a Galaxy S. It turns on, vibrates, and makes noise when the USB is connected.
The phone has files I am trying to recover, which is an issue because the phone was not in debugging mode when it was smashed.
I put the phone in recovery/download mode and tried to ADB to recover the files. ADB will not recognize the phone and kies says "Unsopported connection mode alert" (but does recognize the phone)
Am i missing something here? The phone can use ADB while in recovery mode right? Any help is greatly appreciated and I did a fair amount of searching and couldn't come up with much... Thanks in advance!

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.

Hi all,
I rooted my phone and unclocked bootloader.
My rom is a stock rom.
I managed to install CWM recovery using lg-optimus-4xhd-recovery-v1.0.apk but something happened.
I rebooted my phone in recovery mode and it is always locked to LG logo.
Pressing Volume up and power I can see normal android system recovery, wiping cache and factory reset don't work.
I haven't usb debugging enable so my computer can't see the phone connected with usb cable, and it's impossible for me flashing the phone with kdz rom methods.
What can I do?
Thx in advance for your answers
No one can help me?
Flashing with kdz results in "phone was not found", is there a way to resolve? I've tried with ubuntu, OS (adb) only see my phone if usb debugging is enabled and it isn't, and with a laptop running win8, installing LG drivers and so on, nothing works.
This is salvagable
If you can get the stock recovery mode, all is not lost, all of the important bits are still functioning.
Power down. Hold VolDn and insert the USB cable. If you get the Software Update screen with a green icon you CAN recover the phone. It may require a battle with Windows to get it to play nice, Windows and USB is always a hit or miss affair; but the phone is ok if that screen appears. Do not use the VolUP + Power LG Recovery mode, there isn't a known tool for that in the wild.
I don't normally run Windows and the couple of times I have booted it to do this it required some hassle and usually skipping the nice way since I had never installed the bundled LG Desktop stuff before things went wrong. So just do what I did, pick the Emergency mode that requires inputting the IMEI instead of letting it detect your phone and then let it fix things for you.

Many thanks for your answer, I resolved the problem late at night, yes, after a hard battle with windows.
I installed windows 7 32 bit, I tried a lot of Lg drivers, 3.8.1 maybe the best, after inserting the USB cable with SW Update screen some LG peripherals were recognized but the result in KDZ_FW_UPD was always "phone was not found", then I tried connecting USB cable with the Phone in Android recovery mode ( power & Vol up), and OS added a couple more peripherals, and attempting again with SW Upgrade mode worked.
Dear All,
after a week of struggle i concluded that i may need to go for qhsusb mode for my Lg-F160s, my phone is able to communicate through ADB via lg emergency recovery mode, but i cant do any thing here as download mode is not get detected by PC. when i turn it on normally there will be lg logo flashed twice and then nothing only purple screen but still it will be detected by pc win 7 under com ports and modems,
so can some one tell me about...Test Point guidance for LG-F160s to enter qhsusb_dload mode.
i will be thankful

Well, I'd like to say that I know little English. And I'm using google translator.
The problem is the following
I have a Galaxy S3 LTE I9305T. It was working perfectly. Then I installed a custom rom. I installed a custom recovery then went to the custom rom, the device rebooted and worked normally. The problem came next.
I decided to test some adb commands. I installed all the drivers on the computer. The cell was recognized on the computer as an ADB device. And then I went to do the test, with the command adb reboot download ... then the device went into download mode ... great worked ... it goes out that way ... then I tried the recovery mode, to see if the device I was directed to the personalized recovery of the cell phone ... that's when the problem happened ...
After the adb reboot bootloader command ... the device did not work anymore. When and connected it is only on the screen Samsung Galaxy SIII GT-I9305T, and it is in infinite loop until discharge the battery.
Already tried to get into downloader mode. Power button + homer + volume button down and nothing happens besides continuing on the screen. Trying the keys to recovery mode same problem ...
With the cell phone turned off when I plug in the charger, does not appear charged signal, connects directly to the SAMSUNG GALAXY boot screen, when USB cable on the pc, do not hear the connected noise, just the same problem the screen on and off written Galaxy SIII...
Odin does not work because the cell phone is not recognized when connected in the computer, nor in the charger, but the screen turns on at boot. All drivers are installed
@magogm
That doesn't sound promising....
Firstly, you wanted to reboot to recovery, why didn't you use "adb reboot recovery"? AFAIK, and I might be wrong, but I don't think "adb reboot bootloader" works on Samsung phones anyway. I don't think it should have broken anything though.
If you can't enter system, recovery, or download mode, the next thing I would try is a usb jig to try to force the phone into download mode. If that works, try flashing the stock rom for the region from where the phone is from originally. That is the only thing I can think of that might work considering the device is not recognized by your pc in any state.....
You can get usb jigs cheap on ebay or amazon or elsewhere and instructions if you search. Good luck
Hi to all!
I have a Cherry Mobile One G1, pure stock (Android N, not rooted, no recovery and USB Debugging DISABLED), been with me for almost 2 years bought brand new. What happened was I was going to download a movie then suddenly the phone restarted and its stuck on bootloop. The only thing I can do with it is boot it to fastboot. It can be detected by my pc's device manager as Android Bootloader Interface but ADB terminal cant seem to detect it. Is there anything I can do to revive it? If there is, can any genius mind help me out?
My dilemma now is trying to turn USB debugging via fastboot which is not possible since adb could not even detect my device. If only I can have it enabled, I would know how to fix the rest.
Any help would be very much appreciated. Thank you and God Bless!
This happened to me before. factory reset via stock recovery fixed it. If you can't boot to recovery try removing the sd card first. It will take a while to reset, don't take the battery off while it does and make sure it's charged.
