Pc does not recognize device - Samsung Galaxy J7 (2017) Questions & Answers

I need to flash an os (currently dont have one) but the pc does not recognize the phone. I think it is because I renamed a folder in the firmware directory, not the verinfo. If someone can please tell me the original name of the other folder (notverinfo) in /firmware. Hopefully that IS the problem otherwise ill be buying an sd card to flash an os. Please and thank you. Adb,fastboot,odin nothing will detect the device hoping this is the problem and its not a hardware issue.

rom update without PC

i have no pc with windows. can i update rom on my htc hero just from memory card like i did it with windows mobile on sony ericsson xperia? tnx
The only "official" way to update your Hero is via an HTC RUU, which requires Windows.
However, if you are able to replace the recovery image on your Hero without needing to "downgrade" your ROM, you will be able to update via a zip file on your SD card.
This is very much dependent on the version of the ROM you already have on your device.
Regards,
Dave
tnx
oh thanx! nobody else was able to answer his, i asked on many forums. thanx a lot!
so i just open the file manager on my phone, find the recovery image and replace it, then just go to settings / security / factory data reset ?
where can i find that file on phone?
where can i download the "recovery image"
..if you know, please
Have a look at this guide.
Note that it relies on you getting the APK and recovery images on to your SD card, and in the guide it mentions using a PC, but I think if you download using the browser on your phone you should be ok. However, you may need to use an Android file manager to move the recovery image to the root of your SD card.
If this doesn't work, you have no option (I believe!) but to use a PC to downgrade via an RUU before you will be able to upgrade.

Could you not do it via VM?
Yes you could, but I assume that when the OP says they don't have a PC with Windows, they mean they don't have access to any kind of PC with Windows, VM or no.
If they have access to a Mac, or a Linux PC, they'd be able to copy the APKs directly onto the SD card anyway.

or the operating system he is using... don't see the problem if he is using linux or mac, in fact any operating system that supports usb and has a compiler is suitable to do about anything you can do...

No access to my SDcard from my computer with USB

Hello all !
Everything is on the title.
However, my computer detect the phone (from the disk manager and other program).
I updated the pilots (from Kies), but nothing change =/
From the device manager, I can see a yellow triangle next to my phone : so, it's problem with the pilots.. But they are updated !
I searched a file with them, but I didn't find it..
So, a solution ?
Thanks !
PS : I have this problem since I tried to flash my phone with the last Lestatious ROM.
Have you selected the "mass storage" option?
If you have MTP driver fail then you have to update your Windows.

I'm always using the mass storage option, the begug USB is always set on.
What's MTP driver ? And what do you mean by "update your Windows" ?
Thx !
There is a known issue with old MTP USB drivers(used to connect our devices). I had it too. I looked for windows updates(not new windows version). I mean the patches. I updated them and it worked.
But is your phone recognized by KIES or ADB?
Same problem!!
Guys,
I'm having the same problem. When i use stock i5801DDJP2 and connect to mass storage everything is fine.But after flashing to Kyrillos' or Indroid's ROM with Fugumod Kernel v2.4 beta 3, when i try to connect to mass storage via USB my PC is not detecting my SD card. Don't know what to do.. Any solutions pls??...
EDIT: Sometimes Kies detects my SD card. But not always. And as for ADB, it recognizes the device as an Android device but i'm not sure what to do.

Have you got a link ?
My phone is recognized by ADB, never by Kies (and, I never use it).

Link for what? Updates are available through WIndows update service(implemented in Windows).
What rom do you have?

I always do the update through Windows Update, so..
But I think I've found something.
I'm now testing the GreenMod ROM.

If you have problem with a custom rom then it's better to ask the developer. They know the bugs and the solutions!

SD card not recognized!
Hey Vermillon,
U found a solution yet? i tried everything to my knowledge(which is not much )But nothing yet. it worked when i flashed with stock i5801zhjpf. But after flashing to kyrillos the problem was back.. No luck so far. Can't connect USB storage.
I downloaded a mtp patch, but it didn't solved the problem.
News : I plugged the micro-Sdcard into my computer, and I still can't access to it.
However, my SDcard works, I can take pictures or ad files on it (thx dropbox).
So : the problem is from the SDcard ? Or from the firmware (even the stock XXJPM) which avoid the Sdcard to connect ?
OK ! I've the solution !
Use Linux to connect your phone (I'm running a live Ubuntu, and it works).
I have excactly the same Problem, but unfortunatley im not a linux user, and i dont want to install linux just to connect to the sdcard in my mobile phone.
Maybe someone finds a solution for windows users, i tried already all i could think of including the *#7284# i found in another forum.
I too have same problem. Forcing me to use card reader.

Just install Ubuntu on a USB-key, it's easy even for a newbie !
Then, just run it, not installing !

Well, if you can still use the card reader, where's the problem ? I'd say "lucky you !"
For me the SDCard Reader Solution is workling as well, but its not very comfortable to remove the SDCard from the Phone everytime i want to copy some stuff.
I'm going to try the Ubuntu Solution as well, but i think there must be another way, it seems to be a problem with the Kyrillios Rom, after i flashed it, the problem occured.

If you have wifi you can use "android manager wifi".

I had this problem after flashing Lestat 1.9...
The problem comes from the pilot : in the device manager, Windows indiquates an error code 10, which mean "can't start".
We have to follow this way...
I'm now using MyPhoneExplorer, its working as well.

[Q] SD Card not mountable during ROM Flash, update not possible

Hi guys,
I got me a Defy and wanted to flash CM7/CM9. I got a few problems:
1. What did I do until now?
I rooted with Super one click, es it didn't work with the pushing and exploting the rageagainstthecage-arm5.bin (after exploiting, if the Defy did it properly, it used to exit from shell and the phone remained offline, so no more action could be performed with adb).
Also, ClockworkMod Recovery is installed.
I used this and another push/chmod approach: Cyanogenmod Wiki /Motorola_Defy:_Full_Update_Guide
2. Problem A)
When putting the CM Update zips on the SD card and booting, it will say it can't mount the SD Card.
I mixed some things up and tried to make the SD card mountable again with this approach (last paragraph): Cyanogenmod.com /index.php?title=Motorola_Defy:_Full_Update_Guide&oldid=13776#Problems_with_Android_2.1
By typing too fast i added two incorret entries (shouldn't be a problem).
Somewhere than I read, installing CM7 is only possible with Android 2.2. My Phone says the following:
- System version: Blur_Version.2.51.1.MB525.Retail.en.DE
- Firmware version: 2.1-update1
- Kernel version 2.6.29
3. Problem B)
So I thougth, next approach should be updating to Froyo. Sadly, Motorola Software Update doesn't recognize my phone, wheter with drivers from first link above nor with the drivers that come with the Update center (frankly, I haven't tried first link driver only but Software Update only and both togheter).
Several wipes and factory resets didn't help.
Any thoughts how I could fix this and get me a CM7? Best would be without loosing garantee (I mean sticking with an official software version as downgrade possibility). Should I have updated without ClockworkMod installed? Could return the phone and get me a new one if necessary.
Thanks for your help.
Edit: Is it possible that Motorola Update doesn't work with Win7 64Bit at all?
1st of all you MUST have froyo kernel (but certainly not eclair) before you can install Cm7 properly!
2nd it seems that your SD Card could be corrupted. It's important to eject your device from Windows PC properly before unplugging it. Otherwise you can corrupt your sdcard and/or internal memory.
Here is how you fix both your SD Card and internal FAT32 memory.
1) Plug in the device to the PC.
2) In Android turn on USB
3) The removable drives will show up in Windows.
4) Do one drive at a time. Right click on the removable drive and select Properties.
5) In this screen click the tools tab. Under error checking click the check now button
6) On this screen click the box "Automatically fix errors" and click start.
7) When it finishes it will either tell you if fixed problem or not.
8) If it did fix problems then you will find on the removable drive a folder called FOUND.000, FOUND.001, etc. You can delete those as they are broken files that got corrupt and you probably can’t do anything with them anyway!
9) Now eject the drives properly and you done.
Hope that helps.
Aw, men! I used not to eject any devices from my computer
I will try repairing and the the Software Update Center again.
If not, anybody knows which SBF file from sbf.droid-developers.org/umts_jordan/list.php is the one I would get after updating? I really don't get this list at all.
Thanks.
Ok I checked the sd card and there were no problems. So I switched to "Portal and tools" to check the Defy itself. The the first time Motohelper popped up and said something like:
"Starting the software not possible. In order to start Motorola Phone Portal you have to shut down all Motorola PC software and your phone has to be in one of the following modes: PC Mode, PC Tools or Portal Tools [not readable].
Open USB connection on your device and select either PC Model, PC Tools or Portal Tools"
This message keeps poping up if USB Debugging keeps enabled. Once I disable it and select Portal and tools again no pop up happens but no software (at least visible) starts. Should there pop up something? Start Motorola Phone Portal at device plug in is enabled. Or is this a normal behaviour at all?
Thanks.
Check out device manager in your windows if you have any question marks after connecting your defy to it properly (usb debugging and phone portal on). Maybe you do need some extra drivers on this one.
Well, now i got tired of this and I flashed a SBF with Froyo. Now I`ll trie flashing CM again.
Thanks anyway!

Help needed with TWRP file manager

Hello everybody,
since i am new here i hope this post is in the correct category...
I have an old Galaxy S5 with custom rom, TWRP and Magisk Root.
Since a few months the phones screen starts flickering if the brightness goes below the value 20. So my idea was to set the minimum value to 25...
I found a tutorial on how to set the brightness minimum value and followed it. I edited the framework-res.apk and after that i copied the new one to system/framework. That was a mistake. The phone instantly rebooted and is now stuck on the Samsung screen. Because I have problems to connect the phone to a computer (since the last windows 10 update the phone doesnt get recognized because of the driver (i tried everything to install it but no solution in sight)) i tried to move the new framework-res.apk to a sd card and then copy it via TWRP file manager over to system/framework. Sadly everytime i get an error 1.
cp "external_sd/framework-res.apk" "/system/framework" process ended with Error: 1
I am happy about every hint on how to get this phone running
Thank you very much.

No issue here to connect my Samsung S5 (SM-G901F) to the PC (Win10 Pro 64-bit) and in turn to use Odin. Did you try to install the latest Samsung Android USB Composite Device Driver (e.g. from here)? Alternatively, you can install Samsung Switch on your PC that automatically also installs the driver. Afterwards, simply uninstall Switch; the driver remain installed. If you keep Switch installed ensure it's not running when you use Odin.
And regarding TWRP: Did you mount /system prior to the attempt to move the file?

After the last Win Update it worked. Windows found the driver instantly. I think it was a temporary problem.
I connected the smartphone via ADB and pushed the file to system. Since the space of system was full i deleted a font and pushed the framework res again. Now its up and running. Thank you.

I *may* have bricked my 1+6T

I was moving quickly the other day, and I ended up with a 1+ 6T that does NOT appear on my PC when plugged in. It has a copy of TWRP running and Linage, but I can't seem to change anything. Msm and Adb seem to have no connection, I have gotten the fastboot program to occasionally see the device, and on occasion I see it in my windows explorer. I am trying to get this back to a 'good' state where I can change to OS or make any changes. I am uncertain is both A / B partitions are loaded with Linage. I had this working recently, but made some dumb mistakes.
I am also unable to see the SD partion on the windows explorer any more
How do I fix this mess?
Thanks
Ray

So what is your goal then? I would reinstall latest oos on both slots because who knows what base oos rom was on there. Then put whatever rom on. As far as the PC seeing it maybe the port is dirty or wire is bad I've had that problem. If PC doesn't recognize with mtp enabled in twrp then either your drivers are wrong on PC or the wire or port are bad.
Thanks for your reply. Pretty sure the culprit was a funky windows driver. I finally got MSM to work and restored everything to original. but since then have been having a bear of a time to load anything. More and more thinking that my machine has a problem. I may look at switching over to a different machine.
Thanks
Ray
