Realme 1 issues Android Studio - Oppo Realme 1 Questions & Answers

I recently bought the 6GB, 128 GB variant of Oppo Realme 1. I was excited in the beginning looking at the specs.
But now, I am very disappointed. Even though the phone is great, it isn't serving my purpose. The debug applications run all fine on the phone, the problem is the logcat. No matter what I do, I am unable to get this phone log the events onto to the logcat in Android Studio. I really like this phone and don't wanna just let it go for just this one thing. But at the same time, I can't get my coding done without the logs.
If there's someone with any sort of solution, please let me know.
Thank you.

have you enabled usb debugging?

Hey. Thank you for your reply.
Yes I have turned on the usb debugging..
Here's a list of things I tried..
Disabling and Renabling the usb debugging and the developer options.
Increasing and decreasing the log buffer limit on my phone.
Restarting the device several times.
Resetting the settings of the phone.
Clearing cache both on the phone and Android Studio.
Reinstalling the drivers and reinstalling Android studio.
Changing the USB cable.
Although none of these worked.
Finally, yesterday I factory reset the device and my device is all fine. It started logging again and haven't faced the issue again.
What could have been the proble?? Maybe its one time error?? Hopefully..

you just had to goto
settings->additional setting->developer options
then turn on usb debugging

See my previous reply

Yes I did..
It was just a one time problem. It's all good now..

Thanks
Thanks for the reply Sir. Now I am going to but this phone.

Also it's good to note that adb doesn't work properly when set to mode(USB for Charging)

Almost an year old thread, but can someone help me with adb commands on my realme 1?
1) Do I need unique realme 1 drivers for the device for it to be identified by my PC in the adb list? If yes, where can I get these drivers
2) Will 'minimal adb and fastboot' program work for issuing commands or do I need to get the full fledged android studio?
As of now, when I try to connect (with usb debugging on and tried the usb setting in media, ptp, charging only), it still doesn't identify my device in the list of adb devices
In windows, under device manager, the device is listed under 'other devices - adb interface'

Facing the same issue with my Realme X2 device, it worked for some time and then i tried many ways but it just doesn't show logs in android studio logcat.

Did you ever get this working? I'm having the same issues. I've tried 3 different computers and 2 different operating systems, all that I used last week without any problems. My phone is definitely not in Debug and it's definitely on Mass Storage. What gives?

I don't think it's corrosion. I see all the pins fine with no wear on both the cables and the phone.
i bricked mine awhile back...and it wouldnt connect to windows 7 but would on vista.......dont ask me why but both my wifes and mine wont connect to either pc we have....have to remove external card and move things around like that.....sucks.
Rayn1328: that's what I do right now... move stuff to sd card and then to the internal sd card....
PsychoCemia: Well if it isnt corrosion..... What would be wrong with our devices? Everyone thinks its software issues but it is a Hardware issue....
I would like somehow to help us to repair our bricks! PLEASE!

I did look around a bit more, and found out about a thing called "USB unbrick." Looks interesting, but I can't do it from work, since I don't have ADB/Kies/etc here. I'll try it out when I get home this evening.
Here's a Link.

ViewPad 7 Root

Hello Everybody i just got my viewpad 7 2.2 froyo i want to root it ... when i open superoneclick and click root it stucks and doesn't respond
According to this thread "If there is no activity for more than 30 seconds and the terminal display is stuck at 'Running rageagainstthecage....' remove the USB plug momentarily and plug back in." Hope that helps. Good Luck!

Could never get Super One Click 1.7 to work, it just hangs on "Waiting for device" each and every time, no matter what usb port I use or known good cable out of my desk.
Gingerbreak appears to work, I have SuperUser installed, but I cant connect to the device with ADB Shell. lakehousetech's guide basically comes to a halt at the stock backup phase. I cannot get ADB Shell to find any devices period.

dont forget superuser on youre viewpad ask for permission grant it hope this wil work
Its also worth noting that I cannot actually boot into a recovery mode. On my HTC phone, I press down volume and power at the same time and it will boot into a BIOS/Recovery screen. Ive read that I need to do something similar with my Viewpad, which is to press volume down, volume up and power on in order to boot into this menu, but nothing ever happens. I get the birds splash screen for a few seconds, then the screen goes black.

Yes the buttons do work (this is brand new, not even 24 hours has passed), in a normal operation mode, volume goes up and down. On my HTC phone, it was very easy to boot into this recovery mode, so this process of getting clockworkrecovery mod installed isnt totally new to me. Seems like its going to be hit or miss on this tablet.

Are you sure? Lakehousetech's guide to using Super One Click 1.7 does not mention syncusb.exe. Because of this, Im wondering if the rest fo the guide is correct, because even with my device rooted with Gingerbreak, the rest of the guide does not work.

Hello guys, I'm new here. I'm also facing the same problem in rooting my VP7. Tried different versions of SOC, stuck up on "waiting for device" and SOC stops responding. Tried also GingerBreak, installed and click Root Device and waited for ages and nothing happens. Almost followed all the guides posted here in XDA.
What am I missing? I'm about to give up. Thanks in advance.
same problems....
I am actually in Germany, have a european Viewpad7 and spent hours and days to try to root it. To no avail.
I first read the postings in forums and websites, downloaded the newest (and then the successively older) versions of SuperOneClick 2.2.3. and tried - nothing, its stuck every time before connecting to the device.
Tried different USB-ports, enabled always USB-debugging, tried it with SD-card in or out - nothing. Same result with older versions of SuperOneClick (even using the alternate ADB-parser in "Advanced") - always stuck at the same place before connecting to the device. But - Windows sees the tablet and the card, because the usual window opens (for deciding what to do with the data on the card). Copying pics or music to the card is no problem.
Then - I left the SOC-Road for Gingerbreak. Installed, SD-card removed, runnig forever (25 minutes was the longest I let it run) - nothing. No reboot, no stopping of that little wheel proving that the program is not stuck and runs.
Now, before downloading another potential program for rooting, I became member here at XDA, looking for help.
I run Froyo 2.2.2, last viewsonic update is installed on the Viewpad (bought end of december last year).
I would be glad if someone of the "gurus" here could help me, because I spent three days now and I still don't see the light at the end of the tunnel....

Okay, let's try a fresh approach to rooting the Vpad7 (does your specs. looked similar to mine under my signature below ?) What computer OS are you running - Vista, Win7 or XP Pro/SP3 like one of my older system?
Might I suggest, if you have access to/borrow one - start with a clean PC (I keep an older Dell laptop, XP Pro/SP3 with OEM drivers and basics installed and running, plus Antivirus & Firewall running (easily turned off/shut down as needed) - and easy enough to reformat or restore (if necessary) -
Setup a subfolder on the drive(s) with all the Vpad7 apps, drivers, devices, patches, etc. so that it's easily accessible; and, do the same for ADB & shell/busybox, etc. so that you can run command lines directly from the c:\ prompt (arrrh ...... the good old DOS days)
You might want to have an extra mini-usb cable (OEM or generic) available that is tested to work with similar devices - to play with "trying" out different USB 2.0 ports as needed.
It's possible that one of the self-configured/auto-installed usb drivers from the Vpad7 might be conflicting or competing as you run SuperOneClick (I sticked with v1.7x as newer ones tend to be more problematic per various posts I've read over the past 6+ months.) Turn off pc's anti-virus & firewall, etc. and do a reboot to clear the pc of any background running programs - and pay attention to any prompts, messages, beeps and alerts that pop-up as you proceed (as they often provide important clues to the likely sources of problem)
Follow the posted directions, step-by-step and do it carefully - upon initial connection, does it see a usb connection, recognize the device, attempt to use/run usb driver installation, etc. If it seemed to stalled while connecting or looking for device/drivers - try quickly removing & reconnecting the Vpad7 to the mini-usb cable, sometimes - this trick it into the "mode" to work (one of our HTC DI2 easily gained root but the 2nd. & newer one would "install" for over 3 hours, then a "clean/stock" fresh pc with the connection trick did it - rooted)
If this is still "no good" or you continue to run into problems - please post with any specific error messages or pop-up during the failed attempt, and let's see what can be done then.

Dear Letitride, first of all thank you very much for trying to help. Let me answer your questions one by one.
My computer runs on Vista home, its a laptop and has all the official windows updates. Four USB-ports, all of them working (checked with my external hard drive). When plugging-in the Viewpad, the window with the options how to open the data on the SD-card immediately opens.
I do not know how to access the data on the Viewpad like you did, but I definitely have Froyo 2.2.2. and the last official update, official rom.

Sorry, I don't know anyone at the moment (as I am travelling) with another computer I could use. So I guess I have to stick with mine. But when I do a restart, all applications running before should be terminated anyway. I could also move all the data without any problem to and from the Viewpad's SD-card.

Now you lost me. Which drive? Laptop drive? Where do I get the VPad7 apps, drivers, etc? I have to have them before copying them in any subfolder (subfolder of which folder by the way?). Same question for ADB, shell, busybox. Sorry for my stupidity, I am into Windows, but not into Android....And even in Windows I must confess that I almost did not run anything from command lines. Never needed to....

I do not get any error messages - neither from the Viewpad, nor from Windows. SOC simply stops working, the window gets white and then when I try to close it, it simply states that SOC has a problem in closing. On the second click, it closes.
I hope I was a specific as possible, excuse once again my ignorance concerning android. It definitely seems that my laptop sees the storage device, but not the Viewpad itself. Changing cable or changing USB-ports did not fix that.
Thanks again. I really appreciate your help.

Edited your details to try to keep it short - it read like there some of the device drivers might be missing or need to be installed.
My laptop was reformatted last month running Vista Business & from my notes, when the Vpad was 1st. connected, it recognized the new hardware (Qualcomm USB device) and proceed to install 3 drivers, enabled a virtual CD-ROM drive with additional setup files, and when it was done including a reboot, the laptop has 6 new hardware/device drivers - and both the new virtual CD-ROM and USB removable device available & working, with USB debugging enabled and once the USB drive was turned on (default is off)
Have you tried to go to Control Panel, click & uninstall all the related USB drivers, including a PC Tools apps auto-configured by the Vpad7 ?
Then, shutdown & reboot the laptop - reconnect the Vpad and let it re-install everything from the beginning. (also, do you have a spare mSD card, an older 8GB or even 4GB mSD would be useful ?)
As for the sub/folder - I was referring to creating to making a subfolder on your laptop's drive, and saving/moving all of the vpad7 related donwloads, SOC and custom Roms, etc. to this folder (and subfolders as necessary to keep it organized.) I put the adB and busybox files, etc. here too as downloaded - in order to run adB using the command prompt per instructions - this Android & linux based "stuff" is new to many of us, but to have fun is to allocate some time to learn them. There are links here on XDA on the basics & it's worthwhile reading.
Also, did the Vpad7 install PC Tools, which is used to sync. files between the laptop & the V?

Unable to connect to G3 using adb on Tesla Rom 5.1.1 Arc_Flash 101715 release

So after flashing 10/17/15 release of Tesla Arc_Flash I am unable to connect to the phone through adb without deleting the driver and adding it as an adb device. I have installed the LG G3 Verizon drivers but I am still not able to connect. In the device manager it shows that the drivers aren't there but also that they are there as a portable device. hxxp://tinypic.com/r/30ua82f/8
Also the command prompt is below. Brand new adb server started.
hxxp://tinypic.com/r/71myr4/8
Any help would be appreciated. If you need logs or anything else I am happy to provide it. Also since I feel this may get asked... Yes I have USB Debugging turned on. Have tried with Root for adb on and off and nothing seems to work. I can get it to connect through network but I don't want to constantly have to look for the IP address and port. This was also an issue in the previous release of Arc_Flash so please let me know.
Hi! Exactly what drive did you install and where did you get it from? Here is where I get the driver from http://www.lg.com/us/support-mobile/lg-LGVS985. Try rebooting the PC (without the phone connected) after installing the driver. Using the original cable that came with it, connect the phone to a different USB 2.0 port than you had tried previously - it can take up to 10 minutes to finish loading the driver. When it's complete Device Manager should have a listing for the phone in the Modem section, which isn't currently listed in your screenshot. Until you can get that solved you won't be able to reach it with adb.
Have you searched the Tesla ROM thread to see if anyone else has had the issue, in case it's specific to Tesla?

I searched the ROM thread but found nothing matching what I am experiencing but I followed everything even close to it. I installed those drivers just now and restarted both computer and phone. Still comes up as an unknown driver. There is no modem section inside of the computer still. I can manually add the drivers but it still doesn't seem to help.
Also to add. I also have tried to add it as a modem and it gives Windows Error code (10) that it can not start the driver. I forgot to mention. Windows 10.
Well, I've connected to my phone via adb and used the LG flash tools on Windows 10 last week or the week before, although I have my insider updates set to Fast Ring and I kinda regret it because there was a recent huge push of a beta Windows, and they've broken how I had my video associations set up and I can't get my subtitles to work any more either. Sorry for off topic. My point is since Windows 10 is considered a constant "change in progress", and especially for people like me who joined to get "insider" builds, it's hard to tell what makes things not work. My main reason for even being on Windows 10 is to see what they come up with in their insider builds, but I guess when it mucks with my video enjoying ability, I start losing my patience.
I would seriously consider trying a different PC, or if you have the capability of performing a fresh Windows installation, even of Windows 10, that very possibly would fix it. Or if you just recently, within the last 30 days, upgraded from an earlier Windows to Windows 10, and didn't perform a clean installation, you can revert the upgrade through the the Windows settings. No idea if reverting would solve the problem, either, though.
As @bweN diorD pointed out in another similar thread just yesterday or the day before, when someone in your situation ends up trying a different PC, then everything goes smoothly. As far as the cause, there's too many variables.
If you can't use anyone else's PC, there's an outside chance that you could even do it at a library computer, as long as you don't reboot the PC (which I usually recommend after initially installing the driver, but sometimes things work fine without that). Rebooting a library PC usually undoes all changes, putting it back exactly the way it was.
Let us know how you make out.

Nexus 9, no OS, only TWRP, and can't connect to PC

So... now that I think with hindsight, I did something pretty stupid, and I'm going to need some help, since I have no idea what to do.
I have a Nexus 9 tablet, and I never liked it. The OS is just so slow and laggy, and it overheats, and it has many other problems. Quite a couple of times, I installed custom ROM's and so on, and I never had a problem. Let me explain what I did now.
Around a month ago, while looking on the internet, I heard this thing that if I install the original software, but with no encryption, it would work better. It sounded cool at the time, so I downloaded the Nexus Root Toolkit, and did it.
Everything went well. But then I heard about a custom ROM that was apparently working even better, Dirty Unicorns, so using the same toolkit, I installed it. For the first time, my Nexus 9 actually worked the way it is supposed to work, but the custom ROM still had its problems, it crashed from time to time. I was thinking about possibly returning or selling the tablet, so that's why using the Toolkit, I reinstalled the original software. But, if I went all the steps, and also locked the OEM, my device then showed a flag saying that it was a development device, while booting up. So, after messing around with the settings of the Toolkit a little, I decided to reinstall the software, but leave the bootloader unlocked.
But after some time, I reinstalled my Windows, and I also reinstalled the Toolkit. But that's when I started to have problems. My tablet wouldn't connect to my laptop anymore. I used the toolkit and uninstalled drivers, reinstalling others quite a couple of times, and that's where I think that I messed something up. I managed to eventually connect my tablet, and I rooted it, after rooting it, I connected it again. But adb wasn't working for some reason. A little annoyed, I simply copy pasted the zip file of CM13 into my tablet's internal storage, and I rebooted it to the recovery, TWRP. But the recovery failed to flash it, saying something about an Error 7.
Now that I think about it, I was stupid, since after that, I performed a complete factory reset, resetting my TWRP backup too. I tried to connect it again, nothing. It didn't connect at all. I plug it in, my computer doesn't even recognize that something is plugged in. No Nexus 9, no Android Device, no anything. I booted it in fastboot mode, and it worked, my computer recognized it, and after I downloaded a ROM zip file again, I tried to connect the tablet back and flash it manually, but nothing. It didn't recognize anything anymore.
I tried to reinstall the drivers countless times. I deleted what I had, reinstalled it, nothing. I uninstalled and reinstalled the Toolkit. But strangely, now, even if I know that I installed the Google USB drivers, and the ADB drivers, as I even installed Android SDK, if I use USB Deview, it doesn't show me any of them. I can't see any Google or ADB drivers, although I tried installing them multiple times. So now, I'm stuck with a tablet with TWRP and no OS, which I can't connect to my PC, and I can't use ADB or fastboot.
Is it something from my laptop? I can't check to see if it will connect to another PC right now, so I don't know for sure. Is there any way to delete all the traces from my (failed) attempts at reinstalling the drivers, and to install them again properly? Or is it something from the tablet itself? I don't have an OS, so I can't enable USB debugging.
So, shortly, I have no idea what's happening. And I'm quite obviously a noob in all of these. Can anyone help me? Please?
If you boot into the bootloader and from a command prompt type fastboot devices you don't get anything?
Sent from my Nexus 9 using XDA-Developers mobile app
I still couldn't get ADB to work, but I managed to work out fastboot. It may be something from my USB cable, it works perfectly.
I flashed the original software back, and I'll go to check my cable, although I feel kinda stupid that I didn't think about that in the first place.
Thanks for the help anyway.
If fastboot is working and bootloader is unlocked, you can still install a factory image.
Depending of your device download for wifi Version:
https://dl.google.com/dl/android/aosp/volantis-mob30p-factory-2cb57a1b.tgz
If you habe the LTE variant:
https://dl.google.com/dl/android/aosp/volantisg-mob30p-factory-ae9ce05a.tgz
Extract the files and put them into the same directory link fastboot and execute the flash-all.bat
WARNING: Any data will be erased!!! Also TWRP
Now it should boot up with stock firmware.
If you want your device decrypted install twrp. format the internal storage and flash the pure nexus rom which i can highly recommend and is decrypted by default. Dont forget do flash gapps
my issue is same
what if someone USB- debug is not enabled , is there any possibility to do that , i have a device nexus 9 , rooted it it went into bootloop then i factory reset it , and now my adb is not communicating , if there is any options?

Use fastboot, not adb.
what if fastboot isn't working, either?

Yup. I can boot into the bootloader, and from there (or from TWRP) into fastboot, but no computer I've connected it to (and I've tried many) will recognize it. Doesn't show up in Device Manger or lsusb, doesn't show up from either "adb devices" or "fastboot list devices" (the latter just hangs there saying "Waiting for any device"). The USB on the tablet itself is fine, and I even replaced the USB daughter-board just to be safe.

Hi, uberSkeptic...
Just a quick thought... Have you tried a different USB cable?
Rgrds,
Ged.
Edit & Additional...
The command is not fastboot list devices... it's fastboot devices
One last point... Ensure your Nexus 9 is definitely booted into fastboot mode and not just HBOOT (the bootloader). Take a look at the two screenshots below - your Nexus 9 should look like the screenshot on the right, the one with my green explanatory text.
Apologies for the poor image quality; there's no way of taking a screenshot in the bootloader, so I had to take photographs instead.
Hope this helps and good luck.
Thanks for the advice and going so far as to photograph the hboot/fastboot screens, but unfortunately I have indeed tried multiple USB cables, including the OEM's and I've definitely successfully gotten the tablet into fastboot but it doesn't show on the computer with either fastboot command (devices or devices list).

I'm out of ideas then.
One of my first thoughts was possible Windows driver problems, but as you mentioned you'd tried it on several different computers, that didn't seem to be a likely cause of the problem - I mean, you'd expect at least one of 'em to work! Maybe somebody else can help with a solution.

Sadly, me too. I even tried using a flash drive with a micro-USB connector on it, which I used to use to do nandroid backups, but now TWRP doesn't even "notice" that the USB drive is there (or any USB drive connected via an OTG cable).
Too bad, too - the tablet is otherwise in great condition and even has a custom-painted backplate (long story).
Thanks for trying to help, though!

Mmm... (scratches head, raises eyebrow quizzically)...
If I was Hercule Poirot and this was a murder case, and with all the suspects gathered in one room, prior to revealing a brilliant deduction... I'd be casting very dark glances in the direction of your Nexus 9's USB port right now as the likely culprit here.
Think about it. Different computers. Different USB cables. An OTG cable... And none of them work. What's the one thing they all have in common?
Answer: The USB port on the Nexus 9 itself, and where you've replaced the USB daughter-board.
Maybe, possibly, that replacement don't go so well. Maybe there's some unknown problem with it. I can't comment too much on this, 'cos it outside the scope of my knowledge - I'm a software guy; circuit boards and dismantling devices to fix 'em isn't something I'm comfortable with. I always think I'm going to damage something or rip a wire out somewhere, so I bow to your superior knowledge in this area, as I may be talking complete cobblers here. It certainly wouldn't be the first time.
Anyway... Sorry I wasn't able to help find a working solution for you. If anything occurs to me that might help, I'll be sure to let you know.
Rgrds,
Ged.
I would be suspect if the replacement as well if it weren't for the fact that I did it only AFTER the other symptoms/problems appeared. Hence the replacement (which is known good because the battery charges no problem). There cables and everything inside the tablet tests just fine... It feels like the firmware for USB is somehow corrupt or something.
Thanks for all the advice, though. ?
So I can't believe I didn't think of this before, but when I run "dmesg" from the terminal app included w/ TWRP, I see that there a TON of errors, mostly referencing problems accessing the recovery image. I could screenshot it, if anyone at all might be able to tell me a little more specifically what the dmesg log is trying to tell me...

Android Stuck in Charging only mode - No connection to computer

Hello Everyone
I am putting my problem in this general section with the hope to ask for help to more people compared to the Mate 8 section where not a lot of people go these days.
Since a while I am not able to connect my phone to a laptop. If I connect it to a laptop it just starts charging but nothing else. I have tried everything like:
Changing Cables (tried more than 5. I dont have the original anymore)
Changing Laptops
Changing the USB port of the phone itself
Updating Drivers
Installing Hisuite (current version 5.0.3.300)
Restore phone to factory settings
Complete formatting
Updating to the latest version (Current version Nxt-L29C185B582)
Changing the USB debugging/ Connection (MTP/PTP/etc)
And what not
The problem is, it doesnt get detected on the computer and cant connect to adb as well. All I want is to unlock bootloader and Install TWRP and Magisk. I have the unlock bootloader code but no way to unlock it since I cant connect.
Can anyone help me in fixing this stupid problem ? It is getting frustrating. If there is a hardware issue, what part needs to be replaced? Any help would be appreciated.

Go to the Settings of your phone---> About phone----> Build number tap this 7 to 8 times-----> Developers option is enabled----> back to settings ----> go to developers option ----> enable USB debugging.
When you connect to the phone to the laptop you will find an icon on top of the screen of your phone with a USB mark "like a trident", pull down the top menu and find the USB connection tab, (like changing the sim card if you intend to call through a specific card) e.g quoted, double tap the USB tab to obtain options ---> 3 options 1) MTP 2)PTP 3) USB charging only----> select the first option MTP (Media transfer protocol).
Now connect to the laptop you will find exclamation marks in the device manager of your laptop. Load the appropriate drivers on your computer and viola! this will establish connection with the device you are having. if you find difficulty in installing USB drivers, search the thread "Attempt to load USB drivers for Micromax E484 on win XP is a fiasco" in this forum. You will find the solution for USB drivers

Nope. Doesnt happen
When i connect with the laptop, my laptop doesnt even make that sound for the connection.
What is the model and OS version of the device and the model and OS version of the computer? According to your symptoms your phone appears to be in option 3) USB charging only. The phone will not be detected by your laptop or the like(Computer) in this mode. Merely remains in a charging state. Are you certain the option 1) is picked MTP? If the phone is not detected there appears to be some hardware failure, try another USB port to connect to the laptop. if all else fail a service technician will pinpoint the fault. It may perhaps be a data transmission failure of the devices port to the interior of the phone. This is merely an assumption.
best remedy would be a service technician.
Hope this helps

I have tried changing the usb charging only to all possible options but it still is the same. I tested in Linux and when I connect the phone nothing shows up in the logs. It's like it's not being connected . I have tried changing the usb port itself from the phone but it remained the same.. can the flex cable be a problem ? Mate series was never launched in India so I don't have any help from the service centre. I have to order the spare from eBay.com so there is no qualified technician who can help.. that's why I have to fix it myself somehow..
Thank you for your help

I quite doubt the cable will be the culprit as your device charges the battery while in an established connection with the laptop. As you state the phone USB port was replaced, it could be a some glitch before the USB port in the device where there is an interruption in the data transmission signal that cannot be detected by your laptop.
Could you boot your device, computer and connect the two and take a snapshot of your device (whilst connected to the laptop) and paste the same in the forum?
Perhaps visual cue could be better at dealing such mishaps.

Your USB trident icon is not indicated on the device, If you were to receive power from the laptop the trident would be displayed on top of the screen, even for charging the battery. The power source for your device appears to from other than the laptop.
I have pasted my device after connecting to the computer and the second icon from the top left is the USB Trident icon indicating connection with my laptop. Have taken the snapshot of the menu that I was describing .
I strongly feel you have a hardware failure rather than a simple fix and would require the help of a technician (ordinary if professional is unavailable). Am skeptic you could mend that on your own unless you are proficient in electronics. This mishap is not due to flashing wrongly too, unless you have changed the stock ROM with some custom ROM which has some bug that affect the USB alone.
Take the assistance of a technician whether professional or less is my counsel

I can do basic electronics but the if the problem lies in Mobo .. then nothing can be done .. as I don't have the spares available in India. But I would hate to lose this phone as it was a perfect fit for my needs

If you do not have spares is best left alone rather than tampering with it and rendering the device useless if any untoward incidents tends to occur.
But I would hate to lose this phone as it was a perfect fit for my needs
Send to the vendor directly if you have warranty for the device stating its complaints or request your relative or friends who live in the area where you bought your phone to hand it to the vendor or service technician and bear its expenses

Is there a way to unlock bootloader somehow without connecting to usb ? That would also solve the purpose.. I want to root it for some of the things to work and with the latest upgrade to latest version I lost the unlocked bootloader and root.. if somehow I can unlock and root .. I should be fine without the usb connection to computer.. but I have ran out of ways
Does Kingroot work for you?
I mean did u try it or u just want magisk?
If u didn't, kingroot may be able to root ur device and unlock ur bootloader, then u can flash TWRP using rasher.. & make a backup BTW...
After that, try using the adb sideload in TWRP to test ur connection with ur computer.
TWRP for ur device : (q.gs/DxuAH)
There is a way to unlock bootloader without USB via developers option.
Go to settings-----> About phone-----> Build number ( Tap this option around 7 or 8 times) till developers option is enabled------> go back to settings-----> developers option-----> OEM unlock option (Enable this option) to unlock the bootloader.

There is no FRP unlock, to circumvent FRP you need to factory reset or flash your firmware. The above quotation was to unlock the boot loader as you cannot access through your computer. Your sole option to unlock boot loader was through the above directions.
Moreover, King root application never ask for boot loader to be unlocked. Although a little unstable this is the initial program to root any device. Once you have the TWRP setup then you could switch to Super Su etc. according to your preference.
Could you paste your developers option snapshot here...

when i try to boot to TWRP phone stay on " your device is booting now..."
Your phone has not installed TWRP duly, therefore it boots straight to the system. Search again in this XDA forum, with your pnone name and model number to obtain instructions
