Maybe the USB port of the phone is faulty.
And with the charger?

yeah could be that, but the phone charge with no problem at all. wonder what to do now

I had the same case, charging but no data transmission, I changed the USB charging connector with flexible cable and Microphone.
Relatively easy to change and inexpensive.

Thanks, do you think this kinds of thing would do the trick ? https://www.amazon.fr/RongZy-Connec...TTD9ZD8/ref=pd_lpo_2?pd_rd_i=B09TTD9ZD8&psc=1

USB Power Charging Board Connector Plug Port Dock With Mainboard Motherboard Flex Cable​.
As I said on a post above, there are several models depending on the ram.
But are you the author of this thread or another with an almost identical nickname?

I receive the official loading port in the week I will see (for my version of the phone), yes it is my other account whose identifiers I have forgotten.
After a factory reset the bootloader is supposed to be relock?
Don't know maybe my phone is just stuck with bootloader locked for wathever reason. Because the resseler of my old charging port told me that the phone should be detected soo ...

Unlucky, but not so expensive.

I think the problem is more on the motherboard side but i will see but i hope not ,
With my meager knowledge of electronics I think the flex cable is only used for charging but I could be wrong.
if so I will probably go to another brand for a future purchase

From the usb port to the motherboard it seems to me that there is only the map that connects them.

I believe you can flash a official rom without having hard SPL.
You still need to rename the .nbh file tho.

[Q][Help]Nexus S major problems

SOLVED
Well I hope my Nexus S didn't brick. Well I will start off with what happened. I've been running ICS Slim for a while and I noticed it started to become very buggy. Been busy for a few days so I havnt had time to fix anything. Well today I had some free time so I was going to just connect my SNS to my pc to transfer important files and pictures. My PC (Windows 7) kept giving me "USB Device not recognised" errors. I have correctly installed the adb drivers and have connected my SNS to the same computer. I also tried another connection usb cable to see if my original was defective but no avail. I also tried my netbook with both usb cords becuase I also had this SNS connected to the netbook before (Win7 Also) with correct adb drivers.... still nothing. I then go to rom manager download codename android and successfully install the rom. Tried everything again and still no connection. After shutting down the SNS and strating it again multiple times and trying multiple things my SNS went into "safe mode". Curious I thought there must be something wrong with some system files that don't get written over when a new rom is installed with a factory reset. I decided to turn off my SNS and turn it on one more time and I get this screen which ive never seen before.

Samsung Nexus S i9020a Koodo
FIX:
had the same problem. DEFINITELY FIXED NOW.
Whenever, I connected my Nexus S to any OS a USB Storage Mode dialogue used to pop up and once I clicked Turn On, the PC would find the mass storage. About a week ago, this functionality has stopped completely. I plug the USB cable and nothing happens but the phone starts charging.
I have read many posts about this. I have tried the removing the battery, Rebooting, Trying the boot loader screen, erasing the USB storage, resetting to factory settings, Erasing and dismounting the SD Card from the Boot loader, cleaning the USB Port, trying different USB cables (nokia, parrot, original Nexus etc)....
What has worked for me was the NEEDLE trick. Get a needle and bend the USB hub beneath the phone towards to the top. (What I realized is that it was pushed all the way to the bottom, lifting it up about 1 mm has centered it). I plug the USB and pops up the USB storage mode interface.
So, it turns out a hardware issue, probably a doggy USB port on the NEXUS easily gets disturbed. Using different cables usually helps the problem, especially cheap cables tend to damage the port easier.
So, I would recommend every one to use proper USB cables; the original nexus cable, a nokia cable or decent quality cable. (Do not use the ones from cheap car chargers etc).
Secondly, do not reset your phone for nothing.
Thirdly, keep your phone clean.
I hope this information helps someone. Thanks.

[Q][Help]USB Problems
I just removed my simcard and reinserted it again and my phone started normally.... weird...
But still at problem #1. Cannot mount usb. Windows 7 Still says "USB device not Recognised". My guess is that the usb port is broken. Its quite common apparently so i'm gunna see if Koodo will fix it.
Before I send it in should I go to a stock rom, stock baseband, and lock bootloader. or can I send it in with CyanogenMod 9?

Xperia L dead for good

Hello guys. I've ran into a trouble from nowhere with my phone. I've installed Link2SD to copy unmoveable apps to sd card, edited some things to GravityBox, pressed reboot button, and phone has had never turned on. It's not responding on fastboot nor flashmode. Battery was about 40% and phone was charging. I can't do anything to put the phone back on. It doesn't vibrate when pressing power key, it't just behaving like it has no battery inserted. Battery is good, phone is 4 months old, unlocked bloader, rooted, 1.12 stock, thunderzap 4.1-r2. If you want more info, just ask, I will provide as much as I can. Please help me
If it doesnt respond to fastboot/fastmode it might be better to take it to a service center

Buy another battery before you take it to a service center just in case but you will need to relock the bootloader and restore ta partition or they won't touch it. sounds like a hard brick corrupted boot partition

But the problem is, that I can't relock bootloader, because the device isn't responding to anything. I can't boot in flashmode, fastboot or normally. It is just dead. The PC sees the phone as USB Input Device, or as unknown device.
I've tried different systems, different computers, nothing has helped.

Is there any thing I can do in that firmware download mode? Forcing it to boot an image it already has? Is it similar to U-Boot from other SoC's (like in routers)? If yes, I think I could get it working.

[SOLVED] Lenovo TAB 2 A7-20F Hard Brick (Dead)

I wanted to update Lenovo TAB 2 A7-20F trough SP Flash tool since Android 4.4.2 is really old and kind of useless. I started flashing Lollipop update but after some time flash tool showed error that I can't remember. The device got bootloop. I have seen that I have putted to "Download Only" mode in flash tool instead of "Firmware Update" or "Download Only + Format All", so I tought that's the reason why my device got bricked . Now Instead of just flashing ROM again I used Format Tab in SP flash tool and formated Tablet. And now it's hard bricked. It's not charging or turning on. Not detected by PC when pluged . I tried opening it and removing battery and trying different key combo to put it in META mode since I think preloader is formated as well. If anyone has any idea how can I fix it please replay. I watched youtube tutorials that didn't help . I probably missed something so send help . I guess I have to learn hard way.

Ugh...
I think I have problem. I know for kcolo and gnd method but just take a look at this picture.
This is motherboard of my tablet. Most of points aren't labeled and bruteforcing them could damage motherboard. And there is this big heatsink I guess so , maybe it's under there...
I did find stock ROM, only problem is that it's not detected in device manager at all.
Here is the image the closeup image without heatsink.
These are all contact point I could find. There are 9 total. 4 of them near USB port , 3 near battery plug at bottom that you can't rly see but they are unlabeled , and 2 more that I am not sure about what they do. One of them is near camera and other near sd card reader. Not even sure if these are possible test points.
I was able to find and join kcolo ( volume + and volume - points in my case). Now the problem is that after installing driver and trying to flash I get error 4032 in sp flash tool. I tried older versions but they don't support it;
I tried different drivers but didn't help. If anyone can help pls replay.

Can you provide a picture or explain what you did? I cant seem to find the kcolo/colo and ground pins i need to connect. I would aprechiate it a lot if you gave me an explanation on the process!
You kinda destroyed the whole software by using the format tab. If you didn't, you could've still reinstalled the stock ROM. I have a Lenovo Tab 2 A7-10F that was bricked itself, but I have no idea what's going on

Im in a similar situation, i flashed a Lenovo Tab 2 A7-10F rom at Lenovo Tab A7-20F. Tablet wont get recognized by a computer, nor boot nor show any signs of life. Its like this for 1,5 year. Is it possible to bring it back to life?

It’s complicated. The Lenovo Tab 2 A7-10F and 20F are different tablets, so the ROMs compatible with either won’t be compatible with the other. First, make sure the battery is somewhat charged. The energy transfer should depend on the hardware, not the software. I did unbrick my 10F recently but I was able to power it on and the PC recognised it, although it took some time to find the right drivers. Assuming you’re using Windows, have you checked in Device Manager to see if the device is present? I had the same issue where I couldn’t interact with the tablet from the PC but that was because of the absence of drivers. I don’t know precisely what can be done if it doesn’t even turn on, but it could just be a dead battery (that is, if you haven’t tried to hook it up to the charger).
I was able to completely fix and update tablet to Android 5. The golden points are located at back of the motherboard:
The two points at the bottom when connected should make your device recognized in device manager.
After that you install mediatek drivers onto that device and flash stock rom with SP Flash tool.
I unbricked it more than 2 months ago but I was lazy to write this so sorry for waiting.

The energy transfer should depend on the hardware, not the software. I did unbrick my 10F recently but I was able to power it on and the PC recognised it, although it took some time to find the right drivers. Assuming you’re using Windows, have you checked in Device Manager to see if the device is present? I had the same issue where I couldn’t interact with the tablet from the PC but that was because of the absence of drivers. I don’t know precisely what can be done if it doesn’t even turn on, but it could just be a dead battery (that is, if you haven’t tried to hook it up to the charger).

Thanks for the help but unfortunately I've already lost all hope. Ive tried everything. I don't really care about the device that much so it doesn't bother me.

Have you tried the method I showed above? Maybe your drivers are not installed correctly. Windows should detect device even without drivers and you will hear the connected sound, just like you pluged your USB in.

i think that you are watching in Device manager if your poco its readed, will be like Q9008 or something like that , or if your drivers are bad you will see an 'Unknown usb decription failed"
those drivers are for test point...
i think that you are not doing well the test point.
