Hello:
I have two questions for the users of Tecno phones.
My first question has to do with registering on the Tecno forum.
I've found it impossible to register, because when I attempt it, I find two captcha fields. The captcha can only be filled out in one box.
If I fill in the captcha in to the other box it is invalidated.
I thought the other box is for verification. But no verification code is sent to my phone number.
So, the question is: what am I doing wrongly. What exactly is the problem.
The second issue is this:
I've just obtained a Tecno Pop3 phone, running Android Oreo 8.01.
I found in the specification information for the phone that it has OTG technology.
I also learnt from another source that the OTG can be enabled by going to the settings and then conective devices. Here I find only bluetooth and the name of the phone, Tecno Pop3. I don't find anything that says eanable OTG.
I also found out again that it can be enabled by going to more settings. Unfortunately, I cannot find the more settings menu anywhere on the phone.
So, please how can I then enable OTG on my phone, so that I can connect my USB keyboard to it and type.
I hope my questions are clear, and are well understood.
Please do kindly respond to both questions.
Thanks for your help.

If phone supports USB OTG out of the box - what depends on various factors (e.g. Android/Kernel version, availability of USB OTG drivers, hardware support), then it should be enabled by default.
If not then take note that phone's Android must be rooted to change this.

hey guys came across an interesting discussion! i cant post in dev boards yet... however, this guy provides some answers, maybe some of the elders may want to take a look. EDIT: i cant even post an outside link read code box i guess...
Code:
Hi All,
I've spent some time today dithering on the Nexus S and host mode and I think the way to approach this is different from the Nexus 1 host driver hack.
The Nexus S uses a Fairchild USB switch (fsa8480) to detect device connections. I believe the point is to allow the device to handle multiple functions like charging, UART and USB access simultaneously.
The Switch will detect OTG connections. Plugging in a microB to A convertor with pin 4 grounded to 5 causes the fas9480 driver to wake up and report an OTG attachment. It also calls into the S3C_UDC_OTG driver to configure it up and create a vbus session. (start charging)
The problem is that in the Nexus S kernel, this driver is device mode only. There is no code to put it into Host mode and the chip can only be in Host or device mode. It can't do both at the same time. Also, the few people that have tried to use host drivers have found that they must disable the device code (including charging capability) to get the hubs to enumerate.
It appears that the OTG core in the samsung part is from DesignWare. There are synopsis reference drivers up here:
*************check edit reason for driver link*****************
The register map appears the same, and the code supports host and device mode as well as dynamic switching based on HNP negotiation.
It seems like the best way to approach this would be to integrate this code and use the fsa9480 discovery as the hook to force host mode (when OTG is detected) or device mode when other devices are detected.
The demo we were under the gun to support will probably just use Nexus one, however I thought the rest of you guys would want to see this. I think if done right, you could have host mode, gadget mode and charging all in the same kernel.

Hi folks, apologies in advance if I've posted this in the wrong place.
I'm newish to smartphones and Android, although I've been a successful business software developer on mainframes and PCs for decades. I'm looking for good advice and/or directions to good advice regarding my phone:
Model: Samsung Galaxy 3 GT-i5800
Firmware version: 2.1 update 1
Baseband version: I5800XXJG3
Build number: ECLAIR.XWJH7
This phone has been liberated from Vodafone, and I'm now using Yoigo as my service provider.
I have 2 problems that I'd like to resolve:
The first problem is that the USB connection to PC (Kies or otherwise) does not work. The USB icon does not appear, or if it does, then it does not disappear upon cable removal. Samsung Kies can't find it, so in order to load music or retrieve photos or whatever, I must open it up and remove the Mini SD card.
I've read somewhere else about fixing the USB problem using the code *#7284# but I simply get a "Rejected" message. Perhaps that means that the device is not "rooted", which is another subject I want to explore.
The second problem, which I hope may be fixed just by fixing the USB issue, is that I would like to use USB tethering to supply an Internet connection to my laptop when I'm out & about, away from a free WiFi. I've installed EasyTether Lite on the phone and the corresponding client software on the PC, but they don't seem to communicate. I assume it's down to the USB problem above. Even so, perhaps there's a better way to achieve a good tether connection for this device?...
All thoughts, advice, pointers etc will be very welcome.
Cheers, James
Hi,
You should try the usb cable in another port.
You should root your phone and get proper drivers.
For the second problem you can use PdaNet.
Hope it helped .
I have a device that's evidently called an Edge Mini tablet purchased from the prison system while I was incarcerated. Known issues are battery explosions as mine did. All I have is a circuit board in which Device Manager on pc recognizes something briefly and disappears.
I spent nearly $2k on music and would like to find help on retrieving it somehow.
All I know is that it has a custom Android build and and i cannot view the device on its screen, however thr computer reads it.
Much help needed!

I have never heard of the device that you are using, after doing a quick google search it seems that you should probably contact a business called the keefe group. They are the distributors and provide support for that proprietary device.
https://www.keefegroup.com/home/contact-us-105
Here is the User manual: https://fccid.io/2AHUC-EDGEMINI-AA/User-Manual/User-manual-3073167
If all you have is the circuit board , then most likely your chances are recovering encrypted data are not good at all.
Ideally, you would need to boot into the system and enter developer options, turn on USB debugging, allow an external device MTC connection etc., which allows you to connect to your PC.
On the other hand, its an older Operating system, with less secure software. Perhaps, for a technicians easy access the steps I listed above have already been setup. If so, try downloading the USB driver for that device, and then reboot your PC. If the issue is a driver issue, you should now have access to the internal storage and will be able to copy over your files, by connecting the board to your desktop, using the usb power cable. If the PC reads the device, you should be able to see the internal storage by going to this PC, and it would be under device and drives.
Are you sure that your files are not backed up to a server that you can remotely access? Worst case, I would look into that option.
Good luck.
My Samsung A30 has a broken screen, I’m attempting to transfer all my files unfortunately the phone does not have the file transfer mode enabled so when I plug it in to my PC it’s recognised as a modem.
I’ve attempted to use https://github.com/Genymobile/scrcpy to display my phone so I can perform transfer operations unfortunately it requires USB debugging enabled which I don’t have.
I’ve also attempted connecting my phone to my TV via a USB hub though the phone model does not support HDMI output.
The phone is running as it is receiving calls with it vibrating.
Any thoughts on anything else I can attempt? I’ve already bought a new phone so not too keen on getting the screen replaced especially given there could be other issues.

If the screen is broken and you did not have USB debugging enabled before it was broken, there is nothing you can do to retrieve your data except repair the screen or find a tech shop that has the tools and the knowledge to pull your data directly from the hardware chip itself.
You will not solve this yourself using only software.
Use a USB Type C to HDMI cable to your TV.
The Samsung A30 apparently supports it.
HDMI Alt Mode doesn't go through a hub.
Enable ADB and download.
@Droidriven thanks, fair enough, I've ordered a screen and will attempt to replace it myself.
@Renate To enable ADB I need to enable USB debugging. Also doesn't seem like Samsung A30 supports HDMI output https://www.samsung.com/au/support/mobile-devices/connect-samsung-device-to-tv-via-hdmi/
Oh, sorry, my bad. The internet will give you an answer to any question, usually wrong.
Is there any chance that you can find the hardware serial console on internal test points?
Then you just need to:
Code:
# settings put global adb_enabled 1
If your ADB was previously enabled, then you won't have to deal with the invisible acceptance screen.
If not you'll have to echo the public key into /data/misc/adb/adb_keys
(I just did this on my B&N Glow '21 when it factory reset and it blocked me with a mandatory OOBE setup.)

For one, your solution is not a software solution, which is what I said, that they would not solve this with software alone. That is true and that is all I was saying.
Second, this solution is a hardware approach that the typical user has no experience with, which is why I didn't present them with an option that I am certain they are not comfortable with or experienced enough to attempt, as demonstrated by their attempts with software and unsupported HDMI and then stopping there to ask for help. An answer that more than likely seems more like a risk to them than a solution, isn't really helpful to them. I've helped with users dealing with this issue for years, I've learned that the vast majority of them are not comfortable with resorting to solutions that people like you and I would. With most of them, you may as well be telling them that they can solve their issue by biting a tiger on his ear, they are afraid of the solution. But, I understand, you have a proven, working solution, so you posted it, that is actually good, thank you.
That is why I said to repair the screen or take the device to a tech shop that has the experience and the tools(which requires opening the device to implement a hardware solution, as your posted solution also requires opening the device to implement a hardware solution) to retrieve the data for them(if repairing the screen is not their preferred solution, which obviously isn't). Also, Samsung isn't as simple as B&N hardware, Samsung has some tricky stuff when it comes to hardware, especially their Qcom versions, such as Qfuse(on some nodeld)and other tricky hardware designed to make tampering a real pain or even kill the device with built in components intended to kill the device if triggered. Their bootloader is pretty hard to get past without breaking into the hardware itself also.
Yeah, I know about Samsung, which is why I don't buy it.
In any case, if it's booted to Android, then Android generic solutions will work.
I don't have any idea if a serial port is accessible, but if it were, that would be an easy option.
thanks for the advice guys, @Renate your solution is probably probably beyond my expertise though thanks for your comment, hopefully I can understand it better in future. I'm hoping to use this screen replacement as an entry point into mobile phone repair.
The Touchscreen on my device is entirely unresponsive, which leads me to believe that the digitizer broke (the display is fine and i already tried disconnecting and reconnecting the displays ribbon cable). I already bought a new device but this old phone has some data that i would like to access. I have tried to connect both keyboards and mice to it but it seems to not accept USB connections before entering the password. I tried 2 OTG adapters that work on other devices but not with this one. I can't connect with adb either. is there a way for me to enter my password and gain access to my data?
The OPPO Find X2 Lite has OTG support. Keep trying.

i assumed that it supports OTG, but since my devices didn't connect i thought the phone might reject usb connections before it's unlocked. is this false? i also noticed that it supports otg 1.3 and 2.0, but my otg device is 3.0 . could that be the reason it didn't work?
*edit: it also connects the keyboard in recovery mode
i tried using OTG 2.0 and it didn't work either. predictable but still disappointing.
In order to use OTG you must enable it first in settings every time you want to use it, but with no digitizer you can't do it.. oppo messed up things by not doing this automatically or at least gave us the option to have it always enabled..
