[Q] diag mode?

hi i am wondering how do i put my mytouch 4g into diag mode. i want it to be in diag mode so my computer can detect is as a serial port.
thanks
Oh man,
You've been playing with your bootloader and now you think there's a diagnostic mode. This is the wrong section.
Sent from my HTC Glacier using XDA App
???
what do you mean i have been messing with my bootloader? sorry for using the wrong section
i was asking how to put it diag mode for example, when you dial ##3242# on htc evo, it goes into diag mode so i was wondering if there is a way i can get into diag mode with my mytouch

Hi, how did you fix it. My XP computer doesn't recognize my LG GW825, no matter how I've tried to install drivers. Thanks.

When trying to download an OTA for my LG-D800, I flashed TWRP but then flashed Stock Recovery, but when I tried to update it, it powered down then stayed on the LG boot up screen, and stays there, there is no white text in the corner, no download mode, and of course no recovery. Also now my laptop can't see my phone. Please help me. Thank you!

Do you tried different Usb Ports ?
If you have the Chance you should try it on a other Pc
+ I had to Use my Usb 2.0 Ports the Usb 3 ports never wanted to Recognize the phone
Its a Tricky Process and took me also a while but hey its worth it right

I could never get my cpu to recognize my phone while in recovery.
I used two different computers and couldn't get anything.
When the ROM is working.. I can.
Are you positive you can't get it into download mode?
Try this.
Power off phone completely.
Attach usb cord WHILE holding the VOL up button.
See if that gets it into download mode.
If you can... then you can do the KDZ or TOT "unbrick back to stock" method.
I tried both of those.. but none worked for me.
This one worked for me though:

When it's in the download mode it may show up in a different location in the device manager and be listed only as "android".
Do you hear any sound from the computer when you plug it in when in download mode?
What does your download screen look like?
Once these questions are answered, there may be a solution. Hopefully a CDMA device won't be different

there are two possibilities.. First, your phone is already hard bricked.. second is, your battery is absolutely dead with no power left...
Well, Have you tried to check the battery itself?

how can i check the battery? its non removeable.
thanks for helping, any ideas is appreciated!

ok, so have you tried it using different PC or laptop?
(last option if nothing else to try) if you want to check the battery :
DIY remove the case ( there are several tutorials in youtube, but of course, do it with your own risk)

It's not hard bricked/
Getting into download mode proves this.
You must get your computer to recognize your device in order to communicate with it. So I would not consider anything else until that is accomplished. PERIOD!
1. Are you using a USB 2.0 port? usb 3.0 will not work a lot of the time. (Important)
2. Have you tried another usb cable?
3. I think we discussed the drivers, I have them if needed
What operating system are you using?
If nothing here helps we can we can use "TeamViewer 9" which will give me control of your computer to help resolve this issue...

S4 doesnt get recognized by the Computer

Hey guys,
I read the other threads were people had problems but mine didn't get solved by that. I tried everything from re flashing the Rom/Gapps, taking out the Sim Card & Battery to put it back in, Restarting my phone, Using USB Debugging Mode, trying out different USB ports/cables, installing the Samsung USB Drivers/Kies 3 on my pc, etc.
But nothing I tried helped to solve this error. It started to appear recently but I didn't change anything. My Phone charges when I connect It to my PC but It doesn't show up as a device to transfer files to. Windows doesn't even detect that any device has been connected via USB... Any help is appreciated.
Try this:
dial *#0808# and select AP in USB Settings

Does it get detected when in download mode? If so, then it's either a driver on your pc or something on your phone.

If there even isn't a popup showing on your pc when connecting in download mode, then it's hardware.
Try to clean your usb port or replace the module.

Look, if it doesn't get detected while in download mode then it's:
- Not a software setting on your phone.
- Either you messed up the drivers (unlikely). Remove the drivers completely and it should detect your phone. But it doesn't according to you, so we can rule that out.
- Either you have faulty usb cables (unlikely). You tried multiple.
- Either you have faulty usb port on your pc (unlikely). You tried multiple.
That leaves hardware damage. That seems most likely to me.

Your right that makes sense.. so what do you suggest? I already cleaned the port on my phone. Its weird that it just stopped working from one second to another without me doing anything
