Phone detected as Mobile USB Modem when in Download Mode - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi everybody,
I recently encountered a weird problem with my download mode, and I could not find a solution in any existing forum (wich of course doesn't mean it isn't there, just that I couldn't find it) so I decided to ask away . I have had three android devices over the years, and rooted them all, as well as some friends devices, so you could say that I am an experienced user. I mainly follow tutorials though, I am not a developer. Last year I bought the i9305, and rooted it almost immediately. Since then I've had more Roms than I can count on it, always using adb, fastboot and odin flawlessly.
A few weeks ago, I had nameless rom (android 5.1.1) installed, and an update did not go as expected. I ended up in a bootloop, did a cache/dalvik cache wipe, and when that did nothing, I tried full wipe, back to a previous backup, even fresh installing a version of nameless 5.1.1 I new had worked in the past, but still, bootloop. Fastboot had stopped working, but not adb or odin, so I flashed stock kitkat via odin in order to reset the mess and start over. But since then, even though I rooted again, have a custom recovery and everything running flawlessly (I could flash a custom kernel without a glitch) I simply cannot flash any custom Rom. None. Nada. As I believed a Fastboot wipe could solve the problem, I tried every driver in existence to get it to work again, but my phone still gets recognized as "SAMSUNG Mobile USB Modem" in download mode with samsung usb drivers installed.
Please Help,
Thanks a lot, I'm dying of frustration here.

Update: I think something is corrupted in the phone itself, causing it to be detected as a modem on my computer. I say this because I tried to fix it and now it's also a modem in android . ADB still works though.

What recovery are you using? I don't really get your issue. When I plug in my phone at my dad's computer with Windows 7 it's recognized as a USB Modem too but odin works just as it should. I don't use fastboot nor adb, that's why we have odin/heimdall.

Sorry for the delay, apparently xda's mail notification does not work so well. I don't have a problem with odin or Heimdall, it is fastboot I have a problem with. Since my phone got recognized as a modem fastboot stopped working, so I assumed it was related. Could you by any chance try out fastboot? just download fastboot installer here: https://drive.google.com/file/d/0B0MKgCbUM0itVVFWRC02Q0VBQnc/view and run fastboot devices, so I can know if it has something to do with the driver at all.
Thanks a lot, I really need a second point of view.
Btw, I tried several recoveries available, so I don't think that's the issue.

Can't say much about fastboot. I personally use a Mac and I never managed to get adb and its commands working with the Android SDK. Although I tried several tutorials - my S3 was never detected. I don't have access that often to my dad's computer. Otherwise I'd try it.
What could be an issue is that the Micro USB has some sort of defect. I had to replace mine after 1.5 years and if you google this issue other did have the same issue, too. Even with the normal S3. Could be a reason as well for you.
Sorry that I can't be much of a help now :/

Well my usb seems to work fine in recovery, odin and with adb, so I don't think thats the problem, but thanks for the hint, I'll look into that anyway.

I'm having the same issue with fastboot, did you get anything figured out? Sidesync, ADB, etc. all working ok, just fastboot doesn't recognize device. Device manager sees the phones as a modem when they're in download mode. Trying to use fastboot to OEM unlock my Galaxy A7 (2018), also using my S7 to test fastboot. Tried 2 differnt USB cables. Tried uninstalling & reinstalling drivers, both in device manager (uninstalling device) & programs (uninstalling Samsung & windows android USB drivers). Still nada.
I downloaded the Windows usb_drivers folder (don't recall the sources, but tried a couple) and pointing the "modem" to it for a driver, but device manager indicates no compatible driver in there.
Any thoughts?

Sto avendo lo stesso problema con fastboot, hai capito qualcosa? Sidesync, ADB, ecc. Tutto funziona bene, solo Fastboot non riconosce il dispositivo. Gestione dispositivi vede i telefoni come un modem quando sono in modalità download. Cercando di utilizzare fastboot per sbloccare OEM il mio Galaxy A7 (2018), utilizzando anche il mio S7 per testare fastboot. Ho provato 2 diversi cavi USB. Ho provato a disinstallare e reinstallare i driver, sia in Gestione dispositivi (disinstallazione del dispositivo) che nei programmi (disinstallazione dei driver USB Android Samsung e Windows). Ancora nada.
Ho scaricato la cartella Windows usb_drivers (non ricordo le fonti, ma ne ho provate un paio) e ho puntato il "modem" su di esso per un driver, ma Gestione periferiche indica che non è presente alcun driver compatibile.
Qualche idea?

I have the exact same problem, are at least 10 years that root all my devices for custom roms type lineage or simply for permissions, but without unlocking the OEM I find it impossible to do it

[Q] Help rooting the N-7000

Aight what I have so far is:
1) When going to Download mode please press UP on VOL afterwards so it actually loads the mode itself
2) Then ODIN recognizes it
3) Mine is a KL3, the zImage method always brings me a Permission Denied
4) ODIN now recognizes my phone for downgrade BUT i get a Write Operation Failed.
Moving from Windows 7 to XP 32bit, the Note is installing itself as a modem!
Download and install kies from Samsung.com. If the problem still exists, try another data cable may help.

Try making or buying a download mode jig
http://forum.xda-developers.com/showthread.php?t=927499
That should get you into Download mode, and then it sounds like your computer recognises the phone, so you ought to be able to flash a Gingerbread ROM with Odin and then flash back to whatever you want from there.

I tryed all options and none of all options doesn't work.
When I select 4th option it stucks on "Formatting partition 21"...
4th option is "4 - Repartition your device with preferred layout and bootloader".
Smartflash doesn't recognize my phone even I have all drivers installed.
When I connect my phone with notebook via USB pressing vol- it doesn't show me "S/W Upgrade". It shows me an android picture and I can't use SmartFlash which is the best option in this case.
Probao sam sve druze ne radi niti jedna. Cetvrta mi izgleda ona prava ali zaglavi na formatiranju 21 particije. Problem je sto kada prikljucim telefon sa racunarom dok drzim VOL- onda mi ne izadje "SW Upgrade" nego neka slika androida i ne prepoznaje mi uopste mobitel.
try other usb ports... preferably ones at the back (not usb hubs)...
see if the drivers are installed properly... etc...

P9 Bricked. (Stuck on Huawei eRecovery Mode)

Hi, I tried updated my phone to EMUI 5.0 Nougat from 4.1 on my P9. The update went wrong, I think due to a bad UPDATE.APP file and now I'm stuck in recovery mode where the only 3 options on screen are 'Reboot' 'Shutdown' and 'Download latest version and recovery' (which just tells me getting package info failed)
When I try to use the volume buttons to bring up wipe cache and factory reset it just tells me reset failed.
The only thing I seem to be able to do is hold all 3 buttons down to install update file but all the ones I try get to either 5 or 40% before failing or saying incompatible with current version.
I've been trying for 5 hours to fix it so thanks in advance for any help.
i am in the same situation...
Same here, need help.
wow! you guys should really do some reading before trying to mess with your phones. luckily, its not hard to fix. before anything, always make a nand backup through twrp. this way you can recover from whatever problems you encounter. im going to try and help with restoring back to stock.
1: your gonna need to get the srk tool found here in the p9 forum.
2: run the tool and connect the usb cable to your work station (not phone).
3: power down your p9.
4: while the power is off, hold down the volume down button and plug in the usb cable.
this should put your phone into bootloader mode. by using the srktool you can install TWRP. there are several NAND images available here that can take you back to stock or you can do a fresh install on your own. i hope this helps! oh, dont forget...... ALWAYS DO A NAND BACKUP!!!!
I got it working again.
I downloaded dc unlocker, put my phone in reboot mode with usb and used unlocker to install firmware file from the german huawei site. After tha the phone came back to recovery mode. Then I used the SD card update method with the same file. It failed at 99% hit the reboot button and phone was back to normal.

Che è successo
Ho cercato di flashare una rom e adesso se accendo mi si pianta sul brand, riesco ad entrare in fastboot ma non fa niente e con la combinazione dei tre tasti non succede nulla...
Devi mettere il firmware originale versione l09c432b136 se non ricordo male ) nella cartella chiamata dload sulla scheda SD. Appena riesci a spegnere il telefono premi i tre tasti e dovrebbe installarti il firmware originale. Io ho fatto così e ora funziona perfettamente.
ma a me non entra in erecovery
hi i have the same issue. i've looked around and cant find the firmware file that i need to put on there using twrp . could someone please help, its the ev L09

I think you need to be more specific:
* What did you had installed before flashing with FlashTool
* What did you tried to flash with FlashTool?
* What have you tried to resolve your issue (did you tried with different usb-ports, reinstall the usb-driver in Windows
* Post the output from hardbrick flash you tried (repeat and try again and then choose save logfile and attach it here.
Another thing to try is to try to repair the software with Sony PC Campanion, (I guess PC Bridge for Mac should have the same features)
Hi I saw that the usb port on the phone had a problem of welding of the blow I redone a solder that the telephone and it has well re-worked
