Cannot mount phone as disk drive - myTouch 4G Q&A, Help & Troubleshooting

This was working as early as last night. But now I cannot mount the phone and have the computer recognize it as a drive. I've swapped SD cards, formatted cards, wiped and reinstalled roms etc..
Tried other computers etc..
Is there a setting in recovery?
This all started when I flashed a fresh install using recovery 3.xxxx I've since flashed back to a 2.5 version.
However I've done the same thing on another MT4G and it connects to the computer fine...
???

Same sort of thing happened to me. I was able to use ADB still, but couldn't mount the SD card. I ended up doing the following:
- Flashed the recovery I wanted (3.0.0.6) and did a full system wipe.
- With phone plugged in, went to Control Panel >> Device Manager, and uninstalled all the drivers. Easiest way was to right-click on "Composite USB Device" and click uninstall.
- Unplugged phone and ran a program that fixes problems and errors in the registry.
- Rebooted my computer.
- Went to recovery, wiped data, wiped cache, wiped dalvik, and flashed CM7 again (because I had tried flashing back to a Froyo ROM and it didn't help).
- Plugged phone into comp and let it install the drivers.
Now it works fine. I have no idea what caused it, and I spent half the afternoon yesterday trying to make it work.

Only problem is I'm on a MAC... I have no idea how to get a 'device manager' on the MAC..
This is so frustrating as my other mT4g is working fine.

Can anyone give me a list of things to try?
Mac user
I've tried different cables, a different mac and a windows PC.
My other MT4G works fine in drive mode using the same cables, and alternate computers.
I'm rooted, first using the easy root method then using the gfree method on top.
I'm running gorilla sense 2.3
I've factory reset, wiped cache, wiped dalvik cache, facotry reset again, then installed a fresh sense 2.3 rom-- no luck.
I erased my SD card. No luck.
I put a copy of the original SD card back on and no luck. (thought maybe it was a driver on the SD card)
I have no clue what to do next.
The phone charges when connected.

stuck @ N1 logo after Gapps install,wipe & reinstall no help

I went from 5.0.8 to 6rc2 but forgot to flash google apps again
So i rebooted to Amon and installed and it got stuck at the N1 screen.
Ive selected "clear storage" under bootloader and that didn't help
Now i cant install my nandroid and it tells me to do it via ADB
what am I doing wrong?
thanks for any help
This should be under Q&A.
Anyhow, did you rename your nandroid? If so, the filename can't have spaces. Clear storage means nothing to me.. you should wipe cache and dalvik-cache, flash the gapps, then reboot. See if that fixes it for you.
Havent renamed it ill try that if 6rc doesnt work. do i have to wipe cache and dalvik-cache if Ive done a full wipe?
If your nandroid isn't working it's probably because your battery is low. Plug your phone into your computer.
connected via recovery USB and checked the Nandroid
no spaces
Battery always has a full charge before I flash ( learned that from my g1 lol)
I was tired and let the battery drain over night and tried again just now.
now it boots to the N1 logo and then i get application setup wizard has stopped unexpectedly please try again
Ive wiped and re flashed multiple times and even downloaded the files again this time from mirror sites

USB Connection Not Working

So I start with some history:
SGS i9000
Currently using 10.2.2 (just flashed) JVQ
Android 2.3.4
When I got Darky 10.2 everything seemed smooth. Problems started to occur little by little. Battery drain, always 98-95% when taking off from the charger. Strange tilts, app / screen just freezes and after a while automatic reboot. Strange slowdowns, sometimes friends can't call me...
I think it's all because of custom kernel and rom.
Now I can't connect my Samsung to my Mac. It charges but no connection. I tried different cable, flashing 10.2 to 10.2.2. Wiping everything on the phone. Nothing. Phone is in Mass Storage state, also tried USB Debugging.
It's kinda hard to reflash this thing to previous systems because how do I flash with Odin without usb connection.
Any ideas?
You might try another PC with a fresh USB driver install. I'd suggest a Windows running one.
Restart phone and comp.
@zomirp: i'm not an idiot
I've done everything one could imagine. Tried PC instead of my Mac. Different USB cable. I've reflashed, wiped all data + dalvik cache. I've tried to switch USB from PhoneUtil to Modem and back to PDA but no help.
Boot into recovery and restore your nandroid backup from known working config. You have a backup right...?
Failing that, can't you download 10.2 again on your phone, restart in recovery and install using CWM?
@dolphindos sorry to hear that your phone is misbehaving.
I had something similar, but instead of immediatly blaming the software, I decided to take a look at the hardware.
what are the odds that software changes hardware....
I think your usb connector crapped out just like mine did recently. I went to the repair center got it fixed and all's fine now.
My thoughts have a look at the hardware
Yes that is a possibility. Well I guess I need to find a way to get stock firmware flashed since I can't take the phone with Darky's to manufacturer.

[Q] Screwed up a rom install - new installs don't detect sim/battery stats - fatal?

Hi everyone
Not sure how, at which point and why, but I've screwed up installing new rom, and now while I can install whatever I want, latest CWM 5.5.04 installed, new roms while do start just fine, don't detect sim, battery shows at 0% full stop, etc...
It started with me wanting to update to latest Elite Rom 9.7 based on MIUI by Terramino. Tried 2 versions, multiple re-downloads, every time it would try to install from zip and just returned the install aborted, bad zip message.
At this point phone is wiped to factory reset, dalvik cache wiped, cache wiped, /system mounted and formatted, so ok, need something else...
Downloaded MIUI 2.1.20 (2.6.35 kernel like the one before reset), and that's when I noticed the problem, thought maybe didn't wipe something correctly, so again factory reset, wipe cache, format /system, retry - same issue, after that it's always the same result whether I use CM7, MIUI or whatever.
Following few threads loaded the 5.5.04 CWM in the end, and to my surprise to add to the problem - now when I mount SD card from within CWM to system - it shows with a cd icon in the system and is now read-only, so can't even add anything to it seemingly.
Booting to pink screen still gives debugging access to internal SD card of the phone via usb.
Any ideas from knowledgeable users as to how to fix this problem? Help greatly appreciated!
That elite rom is only for .32 kernel
you flashed it over official gb that's the prob

Thanks, figured that this was the case, just not sure why after trying to load back newer roms meant for .35 it's still messing it up.
Will do full reload of a kernel and get a proper rom to follow suit, hopefully it resolves the issue.

Hd2 wont propperly start anymore

I am using android NAND for a pretty long while now and it always worked great. Untill this 1 night i forgot to charge my phone and all battery is drained. So the next morning i turned my phone on with the charger in and things seemed to be ok and i went for coffee.
When i came back the screen was stuck on the startup, the black screen with "HTC" in the centre. So basically its starts up, MAGDLR does it thing and then this "black HTC" screen shows and gets stuck. Tried removing battery a couple of times and still the same.
What is the best solution for me to do now?
If losing your settings and data isn't a problem (I.e you keep a decent sync routine) then I'd do.....
Enter cwm , full backup, wipe cache and dalvik cache
Reboot,,, fixed?
No..
Into cwm, (you already backed up), wipe data factory reset,
Reboot, fixed?
Yes, see *1
No, start from beginning, full wipe, reinstall rom. Once its working, see *1.
*1 once you have the fresh unset up rom running, (and assuming you are using an ext partition) I'd go to cwm, do another full backup, and then try an advanced restore of just the SD ext partition, (then clear dalvik, since some variants of a2sd move dalvik to SD, and u don't want that restored)
If that's successfull, you will have restored all your installed apps.
If you don't have an ext partition, you could try restoring the data partition, but it'll likely restore the error too.
I did these steps as written but somehow it didnt work. Only on the first boot up it worked. So ive put another android rom on it and its working now.
Thanks for the help

Unable to use as a phone after reflashing

Ugh, I've been flashing since the HTC Touch Elf but I'm finally stuck.
I was using Bobcat, but it wasn't keeping the 3g when the screen turned off, post v13. So I flashed Phoenix which had a troubleshoot for that - which I followed and it worked. Flash the new modem zip using Odin. Thing is, without realising I didn't allow it to finish. I booted up and 3g remained connected fine, so "obviously" it worked, though I never tried to call in or out last night.
I got a voice mail this morning and found I couldn't hear anything during a call - which took forever to connect. Figuring a slow rom, I downloaded and flashed Foxhound - still no calls. So I try the modems again, letting it sit for a few extra minutes until Odor says Pass. But it still doesn't work... It's also quite slow, as Phoenix was.
Any help?
Flash the stock rom again via odin.
Get the stock rom from sammobile
Sent from my GT-I9500 using XDA Premium 4 mobile app
Not what I'd like to do, but I'll give it a try. Downloading now.
I've done it and it still doesn't work. And the camera also doesn't work... Although the camera thing only started after I flashed the I9505XXUFNC9_GSM_LTE_Modems. Not sure that would be the reason for it to work or not, but that's what happened.
I've tried the above modems and I9505XXUFNB9_GSM_LTE_Modems, flashing other firmware in recovery and reflashing the original firmware using Odin.
Have I completely naffed my phone?
Oh, and also the wifi doesn't work since returning it to EE's latest firmware...
Nobody have any ideas?
I had a similair problem. I assume you are still on the old bootloader?
This is what I did:
1. Full wipe in cwm
2. Advanced wipe > wipe /system (this will wipe everything, so it also wipes your sd card).
3. Flash the phoenix rom
4. Flash the modem (I use MJ5)
5. Make sure the modem actually flashed. Check it in settings > general > phone information.
That did the trick for me. Make sure you have proper backups and also a good backup of your efs.
As I didn't have Wifi I had to install Clockworkmod Recovery via Odin. So I wiped everything, but the option was to wipe Cache, wipe System and wipe data. There was also wipe data and data/ (SD card), but I didn't do that one as I don't think the problem was down to the memory card. I flashed Foxhound, as that's what was on my memory card already, put the XXUFNC9 modem on using Odin and booted up. It now connects to 3G and wifi.
However, I tried to call my house and it took about 30 seconds to connect, then when my wife picked up neither of us could hear each other. So it still doesn't work...
When going into download mode, it doesn't say anything about Knox, so yes I'm on the old bootloader still. I don't have a backup of my efs, but I have a complete backup of everything from using Titanium Backup before I tried flashing away from Bobcat.
I noticed something very strange. When I go to About and Phone Information, the phone number shown isn't my number. The number that showed up on the house phone was my correct phone number. Is this related?

I had the same problem as you had. The procedure that I descriped fixed them for me. My guess is there are some files on your sd card that somehow interfere.
I will try doing the same again, but with a different formatted memory card.
Flashed the new bootloader, problem solved.
