[Q] AP/CP USB Switching? - This one goes to the developers - LG Optimus Black

Hey there,...
i got a bad problem with my OB. When i plug in the usb cable the droid does not offer to mount the microsd for the pc. under "phone info -> status" the batterie status also says that it is discharging - thats not true batterie is charging.
i cant connect with adb to my phone but usb debugging is enable. on the original rom i was able to active "AP USB" in the AP CP USB Switching menu in the hidden menu (3845#*970#). After that i were able to mount microsd for pc again and connect with adb etc.
i already reflashed phone with:
v10a
v10c
Nova 5
Nova 7
Nova 8
Problem still not solved. When the USB Cable is plugged in and i reboot my phone it instantly goes to the "S/W Upgrade" Mode WITHOUT holding the volume key. Looks like a flag. this is freaky... could someone explain me what AP/CP USB Switching really does?
Sry for bad english - im a german fool x:

Defective cable?

Hey,
thanks for reply.
Already did the following things:
- Tested Cable with other phone = no problem
- Changed cable = issue still alive
- Changed PC = issue still alive
Must be something wrong with my phone. I dont think that it is a physical defect because when i switch the ap thing everything works fine?
Greets

Damn... Wrong thread...
excuse

Hm,
i think there is no real solution.
Last question:
is it possible to port the lg hidden menu into nova? i really love nova rom and with the hidden menu i could use the AP USB workaround to mount the microsd for my pc.
maybe there is no need for the hidden menu if i could do the same via the terminal...
some ideas? alternatives?
ty for help
PS.: OMG... Hidden Menu is already implemented...

Do you solve this isuue...?

did anybody solve this?
I flashed a lot around today and found this issue with Zeus Rom 6.2*, Marvel 9, Supressed Rom and with rooted v20o (root achieved with smart flash tool).
When I do an emergency recovery and play around with this settings battery starts to load again and after some time micro sd USB drive is also offered. I think that the problem comes from the patched v20o...

Imo this is hardware problem. If you didnt mess around with the hodden menu prior to the problem you phone is failing. So take it to service center.
Btw i remember at least 2 people having their p970 in service center because of failed socket.

Faulty hardware was my first thought. Since I am still on warranty I did an emergency reco to get back to factory defaults to send the device back. After doing this and running on stock V20o without root everything is working as desired - battery recognizes the charger, and when connected via USB I am offered USB mass storage
As soon as I put another ROM in place battery loading and USB storage are a pitty and I have to tweak each time for this to function...
Today I also tested with Zeus V20n branch. Same thing here.

Same story with ac and usb?

[Q] [q] USB BRICK - Devs PLZ HELP!!!

I have a USB BRICK and wishing that someone could help me fix it
[STORY]
My phone was working perfectly until a few days ago when I noticed that USB connection to PC stopped working. I was running imilkas CM9 v2. USB used to work perfectly and then randomly, it just stopped working, I don't have a clue what caused it because I did not flash anything on the phone.
When I connect my Phone to the Computer via USB cable, my phone start charging and nothing else happens. My computer does not even show that I connected a USB device.
I've tried 3 other computers with the drivers and the same issue (1 comp with xp and the others with win 7). Also, not to mention, I've tried multiple USB cables, including the original. I've tried USB Debugging on and off, doesn't make a difference.
I've tried ADB and it does not recognize the device either.
In CWM when I mount USB storage, it does not work.
In download mode, when I plug in the cable, nothing happens, odin does not detect any connection.
USB connection to the computer is Dead and it does nothing but charge my phone. I've searched this issue and I believe its called a USB BRICK
[THINGS I'VE TRIED THAT DID NOT FIX THE ISSUE]
1. Factory Reset.
2. Used Mobile Odin, reverted to my Phone's Stock GB ROM (KK2). On stock GB, I tried Kies Air and that worked fine, but USB connection had the same issue. Also tried Stock ICS via Mobile Odin
3. Formatted the Internal Storage
4. Removed the SIM Card and Micro SD card, still no luck.
5. re-installed CWM manually (without pc)
6. Tried various different roms in the development section
7. Called Samsung... They said they wont service my phone because I'm located in Canada and I have the International Note. They told me I'd have to take it to the country I bought it from.
8. Replaced the micro USB hardware component inside the phone (bought it from ebay)
9. Tried a Jig to see if it recognizes that and it booted me into download mode but doesn't recognize the USB connection to PC.
I've been struggling with this issue for the past 2 months and have gotten sick of this issue.:crying: I've tried all that was possible based on my knowledge and now I need some serious help. I've posted this issue in the Q&A before and about 3 people responded with suggestions that I had already mentioned in thread. I believe this issue might be caused by a file that has gotten corrupted on the phone because i've even replaced the hardware (usb port) and it didn't change anything. If anyone can offer any help/suggestions that would be great. Sorry for making this such a long post but I really need some help and wanted to give as much info as possible.
Thanks in advance.
I had that same problem before, it's really frustrating having tried so many stuff before finally I gave up and went to service center to replace the usb hardware module, which solves the problem. When I asked them why it happened and how to prevent that same thing to happen again, they didn't answer.

I am well versed in replacing hardware components myself. The usb module I bought from ebay does exactly the same thing as the original one. It too charges but does not recognize PC connectivity which means it wasnt the usb module which was defective, its something else!
I would love to send it in for repair, but Samsung WON'T service my phone because I live in Canada and they do not sell the international Note here. When I called them they told me to take it to where I bought it from (which was in UAE). Since I am not going there and have no plans to go there, I am stuck with a phone that can't be warrantied!
Any one know how to fix this issue?
Maybe what you need is just to replace the usb cable... Who knows? (trying-to-help mode).

I've tried multiple different cables, including the original, in multiple different usb ports! nothing works.
I appreciate the suggestions tho
Try another set of driver from Samsung.
The set in the file from link below works perfectly for me:

If it does not work then, maybe, try to change rom. Load a custom rom.zip to external sdcard and flash using CWM.
cheers.
I had the somewhat similar problem, few days back and started a thread.
http://forum.xda-developers.com/showthread.php?t=1732686
Ok here is the solution. It worked for me. Hope it helps someone
1. download latest version of kies for PC
2. uninstall previous kies (if any) and install new one.
3. On the cell phone, dial the following number: *#7284#
Once the last # is hit, the PhoneUtil application is launched. Choose USB -> Modem and then USB -> PDA mode. (Even if the mode is PDA, switch to Modem and then back to PDA.)
4. Plug the USB cable.

Hmm it looks like your issue was different.. at least you were getting some sort of message that you connected your phone. When I connect it to the computer, its as if nothing happened. I've even tried linux and its just that the phone isnt recognizing its connected to a computer, it thinks its connected to a charger.
I tried your suggested solution, still no avail!

I faced a similar problem a few days ago. Here's what I did :
Try cleaning micro usb port by rubbing alcohol using paper strips. They should be thin enough so that you can clean both top and bottom part of the port.Then let it dry under the sun or by itself.Make sure that you don't blow any air into the port else condensation may occur.
By the way, is it monsoon season there in Canada ?

Almost same situation here from the highlighted above. when I plug my charger in the usb it just charge the phone and PC cannot detect it. Also, it only charge the phone when i reboot it. If I unplug the charger while the phone is on, and plug the charger back, it will not charge. However, when I insert the usb cable in my phone, there is a notification in my phone which says "usb connector connected" but the PC cannot detect my phone for mass storage, as well as for Kies and Odin.
My usb port was already replaced by Samsung but same problem still occurs. It could be a software/configuration related issue. Or could it be a usb brick? Pls help.
have you tried to put the phone in download mode and checked if odin is able to detect the phone.. what rom are you on.. have you tried to flash a stock rom ?

LG Optimus black P970 USB Bricked

Please can someone help me, I have an LG P970 but the USB port seems to be bricked. The phone charges when connected to the computer but nothing else. When connecting the phone to the computer, the computer does not see the phone and the phone does not come up with any usb connection mode.
For this reason I rooted my phone and updated it to the latest version of Zeus rom, but this didn't fix the problem. The phone still just charges on the computer but that's all it does.
I think the phone USB drivers are faulty or need resetting. Is there any software APK I can download to fix my phone.
Thanks for any help.

The problem is that when I go into '>> mounts and storage' the only option available to me is - unmount. There is no 'mount usb option'
By default I select unmount - to which as you say nothing happens.
Happy to try further options if you have any?

You most likely have problem with your pc LG drivers.
Download drivers by finding the link for LG driver on this page: http://forum.xda-developers.com/showthread.php?t=1448803

Hi thanks for this. However, the link to the usb drivers is broken. I have installed the usb drivers from the lg website and I know they work fine because I have now tried connect a friend's LG optimus black to my computer and the computer and phone both recognise each other. So I know it's not the usb cable or usb drivers on the PC. I have also installed the LG usb drivers on my laptop and spare computer, however again I have the same problem - phone only charges.
When this problem initially occured about a year ago I sent the phone back to LG and they did some sort of software refresh, which solved the connection problem for a few months, but then things went back to the way they were. I then thought it may be a PC issue so I downloaded drivers and connected my phone to the laptop and everything worked well. However, again, a few weeks later, things reverted back to the same problem. The phone only charges on both PC and laptop now.
Hope you can understand my frustration.

LG service center? you've pretty much tried all I would've
Last time I took the phone there, I was told it might have been the phone port software corrupted. Whatever that mean. If I can't find a fix to this I will need to somehow unroot the phone and try to get it back in its unrooted state to LG (not sure if that is possible) else they probably won't fix it.
I'll keep looking,
thanks for your help.
You are using the the proper usb cord. I know I have a couple. The one will charge only.
Yes I am using original cables, I have three of them. They all work on my Friend's OB but not on mine. I am convinced it's a phone software issue. This has happened with three different computers - when you first install LG software on the computer, the phone connects okay for a few weeks and then loses connection, and I can never get it connected again.
When LG refreshed the phone software for me the phone worked properly for a little while and then reverted back to charging mode only.
I need a way of reinstalling the USB software or port software onto the phone itself via some type of APK if such a thing exists.
Maybe a developer here can develop one???
hey man
if you have disabled the "android platform usb modem" in peripherals manager, enable it first (phone must be plugged)

this means it must be the result of an intervention by a third party thing, by yourself, or another program. If you have a kind of a software which manages ports or consumption (on phone as well as on Win), uninstall them, then uninstall all LG drivers, reboot, then reinstall them. if that doesn't solve your issue, you may have to reinstall windows. that's radical, but it should do it
Try connecting the usb while doing pressure between the LG logo on screen and the back of the phone, like squeezing something . I had this issue and it was an internal connector issue....
Check if you hear the "tada" sound in windows or any message about a new device.

Hi, thanks for this, I'm not sure what you mean by "disabled the "android platform usb modem" in peripherals manager". I am using XP. I have had a look to see if there is any software remotely associated with port consumption etc and have uninstalled these and also reinstalled LG drivers. But situation is still the same.
Please note: I have an LG GT540 and this connects fine to the computer. I have also connected another LG optimus black and this also connects fine to the computer. On the basis of deduction, it must be a phone issue, somehow interacts with the computer fine and then fails after a little while. Also I haven't installed anything on the phone itself which might manage consumption or port. The computer has a usb host controller but not sure that means anything useful.
I do agree and have feeling that if I reinstall windows I bet the phone would start working again, possibly again for a few months. This means I reinstall windows on my pc and laptop and hope it all resolves without actually getting to the bottom of the problem.
What I need is another laptop to try this on. If I try another computer or laptop and it recognises the phone. What do I make of everything??? Any ideas.
ps also tried holding pinching usb lg cable as suggested but nothing different.
Thanks for all your efforts.
Further update to this, I installed LG drivers on a fresh dell laptop. Again nothing happened, the phone only charges. I am even more convinced that phone software is corrupt. How do I reinitialise phone USB software?? If there is such a thing.

Make sure the cable is properly connected. Check for dust that might prevent it going in properly. Try a different cable. What OS are you using? I found where bootloader is dmg or incomplete Windows fails to detect it. Linux on the other hand detects it. Can't use it but you can detect it.
Can you connect to SW Update Mode? Battery out and plug into PC while holding vol up button.
If nothing works try taking it into the shop.

You can root your phone from there. If you have SW Update. I recommend taking it into the shop if you are still under warranty, If you don't have warranty then you can go ahead and root. Just install a patched bin and fls with Smart Flash Tool. It's one of the stickies (How to unbrick, I think)
hi
new to Android nation
I have the same issue when connecting to USB...
And I managed to flash with custom firmware (latest ZEUS version) and I rooted but the issue with USB connection is still there...
Anyway, I wiil try connecting it to Linux to check if that would work with USB connecting
UPDATE:
OK after some digging, I managed to (at least temporally) solve the issue... After fresh installing official 2.3.4 firmware I booted to recovery and from there formatted the system folder and then installed Zeus v7 firmware... anyway, USB connection and charging indicator work fine at first booting to system... As soon as I reboot the OS USB connection (and charging) get unstable, and after third reboot it completely goes away and the device does not recognize anything: if I connect USB cable it does not show any sing (charging indicator does not show battery charging, nor the device offers me to connect in mass storage, windows recognizes only modem but not the USB storage) and when I connect charger, battery indicator does not flash as charging... Battery monitor tool shows that "battery is discharging" even though the battery capacity seems to increase (according to growing percentage of battery capacity)... Is there a some kind of USB server... I am a total noob to Androiid OS (used to be Symibian from its beggining )so I hope you won`t mind if I used wrong terms in my explanation/comment...
I hope my explanation is not confusing
Cheers
UPDATE 2:
After installing Zeus v7.01 update, battery charging recognition got fixed using both USB cable and wall charger...
Anyway, USB recognition by PC problem still exists... But when in recovery mode I can successfully mount SD card to PC in Mass storage mode...
Will keep you updated... :victory:

[Q] I9000 Screen Shattered - Need Data Recovered

Hi everyone. I have searched the forums with no luck. I have a I9000 that has a shattered screen and as a result there is no image on the screen nor will touch work at all....I know, big surprise right? My goal is to get the data off of the phone. The phone is booting as I can hear the sounds and responds to Doanload/Recovery Mode commands etc. Before I would plug it into PC via USB and I would have to select one of three options on how the USB should behave. One of those options would enable Kies to access the phone. Because the screen is damaged, how can I force the phone to connect with Kies, or the computer for that matter?
All help is greatly appreciated.
Chris
hi, it will depend on what the usb is set to, if you switch the phone on and connect to the PC you should be able to use it as an external disk. If not start Kies then connect and it should connect, then you can recover your files

Hi thanks for the reply. Kies actually doesn't recognize the phone and suggests that I turn on Developer Mode (if I remember correctly).
I read of a way to recover the data by activating the Recovery Mode and plugging in to USB. The issue there is I would almost need screenshots of the menus to try and navigate through and mount the device since the screen is unusable.

Strange experience, you can also try some of these options:
(i) Can use the TV out cable so that the screen is displayed on an external display [Use the 3.5mm TV out cable, even Nokia TV out cable works]
(ii) For using recovery, you should know the cwm/kernal that was installed, as the menu options vary? if not, what last ROM version you had installed, this may also help you get the exact recovery menu options.

I will try that with a 3.5mm to RCA that I have from a digital camera and see if that works. I have never rooted the phone so it's stock and whatever the latest Android version for that phone is. I THINK its 2.3.1 but not sure.

[Q] Problem with connecting LG P970 to PC

Hello people
I'm new here, in terms of asking questions and seeking help
I have the LG Optimus P970
A few days ago I made ​​the update to ICS, and by proceeding with this page, hackmyandroid.com/optimus-black-p970-official-ics-update/3299
After that, not impossible to connect the phone to a PC, even the software update mode, it can not recognize, anyway to connect it just throws a slow charging.
Is there someone who knows what it is.
I'd love to go back to the old software, but there is no way to detect it pc
Sorry for my bad english
Thanks in advance
I forgot to say, before the update, and my computer still recognize the phone, connecting it over sony usb cable, now it is no longer recognized by the Sony USB cable, and I do not have original LG USB cable.
Perhaps this is the reason why a computer will not recognize the phone

Your problem can be the non original cable or........reinstall the drivers and try again

I have the original cable, but still the same problem.
I have all drivers installed, I can transfer files between the phone and the pc, I can use the LG suite,
But I can't see my phone on the ADB console, I can't use smartflashtool cause the phone isn't recoginized.
yesterday I tried with lg cable, and wall charger, in both cases, said slow charging the battery, I tried on three different computers, I tried to reinstall the drivers, like the software blocked communication with the phone, just charge the battery.
If there was a way to put the software through SD card, it might solve the problem.
even the software update mode, the computer does not see the phone
Bro! For the softwaretool like smartflash, You need to boot into download mode i.e., You need to switch off the phone, plug in the USB cable connected to the PC and instantly press the volume up button. Then the tool will recognise Your phone. Try it and check once!
I tried it, nothing happens,
I go to download mode, but computer does not recognize it again
behaves as if the port is destroyed

Try to boot your PC with disabled driver signatures, or use a 32bit windows system.
try entering download-mode the following way:
disconnect your phone from pc
remove battery
press and hold Vol-up
connect the usb-cable (still without battery)
Now the phone should be detected as a serial-cable device an you can use the smart flash tool.
would have to be sound,
no sound when I connect the phone to the PC
Solved my problem.
Seems like windows automatically installs driver to the phone, but it partially works.
Unistall all drivers for the phone, or try on a new computer.
Plug the phone and cancel the driver search by windows
Install drivers for LG (unplug the phone before)
Turn it off
Plug the cable and enter download mode
And there is the phone recognized on smartflashtool.
I'm flashing a new one right now, thank you.
You do not understand the problem
there's no sign, no sound when I connect the phone to a computer, any computer, drivers were or were not.
As if something in the phone blocked communication between the PC and phone

Connection Problem with Mackay 2.999
Hey Guys,
first of all, sorry for my not so good English
I'am at Mackay 2.999 with last Kernel of his build and can't connect the Phone to the Computer.
It only install the LGE Mobile Composite USB Device, the LGE Mobile USB Serial Port and the LGE Mobile USB Modem on connecting to the Workstation.
I had test it on many Computers but the Problem is all the same: I can't get on my Memory or ADB.
I also had testet all modes under the setting point (MTP/PTP/mass storage device) and with debbuging on and off.
On my Workstation is the Last Version of ADB (1.0.31) installed.
Did anyone know the problem?
Did no one know a result to this problem
Hmmm my PC also can't read my storage what I did is go to cwm and plugged in usb cable and pressed mount storage it seems to solve my problem. I also did a cache and dalvik cache wipe.
Hey, I have found the result to this problem. You must flash another Baseband. Use from Nooby the V30 Baseband and it is solved.
