Unable to Connect phone to PC or OTG! - Android Q&A, Help & Troubleshooting

Hello Dear Community!
I tried lately to flash a custom rom to my Mi 10T using OrangeFox Custom Recovery.
The Problem is the flashing operation didn't complete successfully, and a result the system partition is empty. in other words there is no rom installed, as many of you are thinking right now - Okey bro flash another rom - , The Problem is my phone do not connect to pc - I tried many Cables and many PCs - and I changed the charging port with new one many times , so I am sure it's a Software issue.
if anyone can help I will be grateful.

Micromax A52 (ROM Backup Generic)

Hi friends,
I recently bought Micromax A52. Thought of rooting it and after looking on xda i figured that existing root methods didn't enable root privilege in Micromax A52. Thinking of trying the manual way to root ( Creating own methods to root).
I need your help in getting basic idea of few things.
I dont know/find where i can download A52 stock OS. Pleas guide me the process of backing up stock.
After stocking original os as we can easily restore to it, would like to proceed with the rooting steps. Wondering how a rooting softy (Superoneclick or z4root etc) works based on which i will be able to give a shot on it.
I know the queries here are silly but if you help me i could learn to master ..
Thanks

Thank you sharmad247. I tried them but failed. First of all it was because of MT65xx Preloader failed driver at boot and later in Factory boot mode identified the chip is MT6575 and searched for that particular driver. (Tried rooting as well)
Got the drivers from

and installed successfully.
Now started Smart Phone Flash Tool again and configured Readback.
Disconnected phone from Data Cable.
Clicked on Read Back button on Flash Tool.
Switched off phone. Removed battery.
Connected Data Cable.
Inserted Battery.
Press and Hold on Vol - UP / Down button. (Tried both ways)
Flash tool detected the driver (showed on status bar) and popped up the error attached.
Please try and let me know when you are successful in making backup (I can understand where i went wrong), Also please share backed up rom.
If you also want to root, I tried lots of possibilities but seems i missing some steps and rooting not successful yet.
Thanks

No luck with me too
This seems to be 'Download Mode' error which our phone does not support or does not have it. But has a recovery mode with limited options.
I too tried this on Ubuntu 11.04, but no luck.

[Q] help after installing miui rom cubot phone hustle

hi! i have cubot s208(a) . i rooted,yes. my problem with the phone was it was slow and laged specially watching videos. everyday i could do nothing but restart it. so i thought nice hardware but the problem must be rom or kernel so i decided i install custom rom. but there are no for this phone exept i found on this site miui v5. i did some backup with MTKdroid tools.(image is still on my pc,but unfortunatelly not on my phone) i put miui rom on internal card,i went to cwm there i wiped cache and data...install miui zip file all no problem,but after reboot on cubot logo some funny colours and then just black screen...nothing else happens. i went to cwm again tried restore but no backup there.i tried install backup with MTKdroid tools,but phone wont be recognized. i tried put images from pc to sd card but it wont work.i tried flash tools,i downloaded 2 firmware stock roms (unfortunately they aint zip) but again flash tools wont work because it wont connect with phone.(with usb cable) if i just connect phone with pc it auto turns him on.i tried zipping those 2 roms,but after trying in cwm it says install aborted (way i figured i need real stock rom but in zip file) funny no way i can find it.only roms that i can use with flashtools.
so...anyone knows what can i do please say
edit
i fixed it
somehow i suceeded installing mobistel cynus driver (for usb) then i went to sp flash tools. there was other problems... but there i first format phone.then just flash preloader.then everything else.et voila!only problem left is invalid imei.but i guess it will be easy to fix,right now i go to sleep.last 30 hours i slept 6 hours,other time i spent on pc.hope i help somebody.dont forget to backup your phones!
good night and good fight!

[Q] Phone is dead; can't flash ROM nor recovery!

Hello
I bought a Lenovo p780 from a Chinese website 6 months ago (4gb), rooted.
I faced a problem with the signal of sim cards "invalid imei", so I tried to install TWRP recovery using a tutorial I saw online to use the recovery to install a new "modem" file. I used Mobileuncle app to do this but this step caused my phone to enter a bootloop, and the only way to get rid of this loop is to press the reset button whenever you want to turn the phone on! I tried to install other recoveries using Mobileuncle but nothing has changed too!
I also tried to flash a stock rom using sp flashtool but it just didn't work!! I tried many stock roms versions and many versions of the flash tool programs but when I press "firmware upgrade" or "download" nothing happens! believe me I tried everything to make this happen, I even tried to do this on different computers (win 7 and win 8.1) but I got the same result: nothing! No need to mention that I've already installed all the USB drivers on my computers. I read every single word in every single tutorial I found (including tutorials from this forum), but it's always the same failure!
I tried to change the modem file using Root Explorer but I missed with some folders and now even the Wifi doesn't work. All I need now is get my phone functions as normal with stock rom or with a custom rom.
I would be very appreciated if you can tell my what's wrong and why I can't flash a rom to my phone although it's not bricked at all and I can turn it on!

problem flashing recovery lenovo golden warrior note 8 (a935)

Hi everyone !
just got this phone from my friend and the official rom is terrible , slow and having all this chiniese apps.
so i wanted to start by flashing custom recovery with sp flash tool but with no success , the download wont start.
im having windows 10 , may be a driver issue ? (the phone have to be off and connected to the usb cable and i think that the computer dont recorgnize it that way)
Any ideas of how to make it work ?

xiaomi mi note pro only fastboot

hello i have i mi note pro that has been bricked for a while and im trying to fix it.
i think it has 2 problems that has to be solved but im not sure.
first thing that i tried to fix was that the device only started up when i was charging it from an adapter. when i connected it to the computer it just flashed the red dot with second in interval. i searched for a solution in forums and found out that similar problems had been solved by pulling the battery out and putting it in again after some minutes, but it did not fix the problem. and thats when i get to the second problem.
2nd prob is that, when i get my device started ( by having it connected to the adapter) it only flashes the mi logo. And i realized that i could start fastboot, and then quickly while fastboot is on connect to my computer. when i write sudo command "fastboot devices" i can see that it recognizes the device. (fastboot is unlocked also if that is to any importance.)
When i last used the phone i had a twrp and an unofficial ROM installed and it got bricked because i tried to install a new twrp or ROM, i cant remember.
I have a feeling that i tried install either a twrp or rom that wasnt compatible with what i had. i had marshmallow 6.x on the device and i think i tried installing something older or probably newer like nougat 7.x
i was wondering if i could some how install a new clean TWRP and ROM on my device trough fastboot so i can continue using this device again.
i would be grateful for any response or help

hey, thanks for the reply! i did try that tutorial on unbricking my phone. but i only have an laptop with linux on it and, 2 of the steps are not possible for me to do (install MiFlash and finding any Qualcomm HS-USB QDLoader 9008 drivers for linux).
i've tried to install a new rom through an unofficial tool that i found here on XDA - https://forum.xda-developers.com/android/software/tool-miflash-linux-t3708847 . But i haven't had any success with it yet.
maybe if you would know how i can force install a new ROM on my phone through the terminal on my computer the problem might get fixed?
