Not showing up in MTP - Lenovo P2 Questions & Answers

I couldn't find a thread for this particular problem I'm facing. The USB file transfer doesn't work because the phone doesn't show up. It used to before but it suddenly stopped. It appears to be a driver problem according to what Windows is showing me but I've already uninstalled and reinstalled the drivers including a reboot twice without success.
Any tips?
EDIT: Never mind, I should've taken the 5 minutes of googling instead of making this thread. Anyway, was a Windows-related problem unrelated to the P2 in particular.
In case anyone runs into the same issue, navigate to C:\Windows\INF, search for "wpdmtp.inf", right-click the file, and install.

You have saved me from all the painful downloads, reinstalls, reboots and what-nots. Thanks for coming back to post the solution! I really can't thank you enough! Your solution worked instantly after several hours of fiddling with files and looking for answers in the Lenovo Support pages. Thanks a lot!

Activesync upgrade problem

Hey everyone, this is my first post here so I'm not entirely sure this is the right place to pose this question. Earlier today, I made the decision to upgrade my Dash to WinMobile 6.1 using the resources here at this forum. The upgrade went nearly flawlessly with the excption that I need to copy the correct keyboard settings cab file still. However, I'm unable to do that because of Activesync.
I had 4.2 installed on my laptop and it never gave me any problems. Unfortunately, the phone displayed a message that I needed to upgrade to 4.5 in order to connect to the PC using Activesync. I downloaded the file from Microsoft's website and tried to run the install program. After clicking the "install" prompt, I get the following error message: "The System Cannot Open the Device or File Specified" Retry or Cancel. Retry gets me no where. I have spent at least 5 hours not trying to find a solution to this problem including a LOT of searching on Google, here, Microsoft's site and other places. NOTHING. I've seen a couple of references to this problem but no definitive solution to the problem.
A few things I have tried: Disable Firewall; uninstall Activesync 4.2 (curiously, after using the Add/Remove Program tool in the Control Paner, there was still an Activesync folder and dozens of files on my hard drive...I manually deleted as many of these as I could); Ran a file called "fixmapi.exe"; and I downloaded the upgrade file from multiple sources, all of which were suggestions I came across during the day.
I'm sooo frustrated because I can't update the keyboard map, I cant synchronize the hundreds of contacts and calendar items I have in Outlook, the phone feels completely useless to me at the moment and I cant believe that this is such an unusual problem (which is my conclusion based on such a complete lack of guidance on this issue).
anything anyone can offer will be HUGELY appreciated!

Hour 3 of unsucessfully attempting to update Rom

Alright I'm finally going to throw a post up, go ahead and get all your "use search" "it's on search" "it was in a thread" out of the way now, cause I've gone through 76 thread pages of reading and searches and I can't find an answer that works.
I am continually getting the ERROR 262 in RUU everytime I attempt to use it to flash.
- I am running Vista 64bit (not sure if that is the problem or not)
- Using WMDC 6.1
- I have uninstalled and reinstalled WMDC 6.1 a total of 7 times
- I have used every single USB port on my computer.
- I have restarted a total of 15 times, both the computer and hard resets of the phone.
- I have tried both the Unlocker (I'm not sure if I have to unlock a second time or not after my WM 6.1 update) and just the ROM Update.
- I have tried doing the forced bootloader mode (Power+Camera+Reset) and simply allowing the program to do it on it's own.
Everytime it drops into Bootloader (3 color) mode, it drops Activesync and then obviously errors out because of lost connection. I've tried simply running the program and never unplugging the USB cable, I've also tried unplugging the USB cable when the DOSprompt part of the batch tells me to. Everything I've read says to do this, but I don't remember doing this for the 6.1 WM Update. It also doesn't make sense.... if you unplug the device, it's going to drop activesync everytime....
I've just updated every program, reinstalled everything more then 5 times, done countless resets, tried every USB plug and nothing is working. Hopefully this is something easy I'm just overlooking -- or something easy like "It doesn't work with Vista 64" so I can at least get an answer.
Again, I apologize if this was answered somewhere previously. I genuinely tried for 3 hours using search, on and off XDA, so that I wouldn't have to post a question thread but never found a "fix" that worked.
Thanks in advance.

Try another computer. It does work with Vista 64 (I've done it many times), but there's no point in beating your head against the wall for this. There are so many things that it could be you might as well try another computer so that you at least now it is the computer and not your Vogue.

You phone is not unlocked and you are trying to flash a custom ROM.
Try following the instructions in this thread found about halfway down the first page of the forum.

Be it locked or unlocked is beside the point. As I stated before, I unlocked it once for the WM 6.1 upgrade and being as I wasn't sure if I had to do it again, I attempted to do it again.
Regardless of if it's trying to flash the ROM, or use the Unlocker, the same thing always happens. Windows Mobile Device Center (ActiveSync) drops connection once the phone goes to the Bootloader (3 color screen), and it errors out 262 (Connection Lost).
I have attempted to give as much information as possible so I can get input on if I'm missing a step or if it's simple bugging out. I will try what gt! suggested and attempt this on a different computer. However, from the information I've given can anyone confirm that I'm at least doing the correct steps -- there's just some gremlin popping up keeping me from completing it?
Thanks again.
Flash via SD card. There are instructions in CodyBear's FAQ thread.
From experience...use a blank or backed up card.

CONNECTION DROPS BUT............ it should be installing new drivers.
When i flash my phone on windows 7 it loses connection when it enter bootloader just like you.
And by the time the drivers for the qualcomm chip on my htc touch vogue gets installed (this is the recognized driver when your phone is in bootloader)
the RUU rom updater/installer times out.
After it times out for me i make sure that the driver for the qualcomm chip (the driver that is seen by windows when your phone is in bootloader) is installed, i run the updater again.
Now it should run through smoothly again.
Alternate method:
Flash by ur sd card.
or
Try a different computer.
start it up on serial mode then plug it in to USB, go to device manager make it search for new devices. Driver should start loading and start RRU, if all else fails use the SD CARD for The Flash
Alright, well now I guess a second question looms. I was going to take everyones advice and attempt to flash with the MicroSD Card, but now I'm having problems with that one as well.
Yes it has to be 2GB or less and formatted FAT32
I always find my original 512MB works perfect for flashing from
as to how to get it to your card...
Extract the ROM you want to use
Find the largest *.NBH file and copy it to your desktop
at the desktop rename it to VOGUIMG.NBH (I believe the caps in naming is important)
Copy that file to the root of your formatted FAT32 2GB or less SD Card
enter bootloader mode and it should go from there.
Click to expand...
Click to collapse
Those are the directions on the FAQ. I have the original 512mb card, formated to FAT32. I went into the Unlocker RAR, found the Voguimg2.nbh, renamed it to VOGUIMG.NBH as instructed in the FAQ. Placed the file on the freshly formatted MicroSD Card, put it in the phone and went to bootloader mode and... nothing.
I attempted putting the card in, then going to Bootloader. I tried going to bootloader, then putting in the card. I tried putting it from USB to Serial and vica versa. Tried hitting all the buttons. Nothing happens, it just hangs out on the 3 Color Screen.
Am I missing something, or am I just cursed to not flash my phone more then once? Heh. Thanks again for all the help.
[EDIT] For clarification, since I don't know if I have to unlock before every flash or not, I'm just attempting to unlock it again and hense only using the Unlocker ROM. It was previously flashed for the 6.1 update, but I figured it couldn't hurt to try the unlocker again so that's been the ROM I've been trying to run currently.

As explained in Cody's FAQ, once your phone is unlocked to flash, it stays unlocked. The only thing you MIGHT want to do other than just flash the new ROM is to flash a stock ROM, then the new ROM.
Go ahead and try putting the VOGUIMG.NBH from the ROM on the card and see what happens. From what I remember, you should have the card in the phone then put it into boot mode. I believe that was what I did for my first flash ever.
What method did you follow when you flashed to 6.1? Has anything changed about what you are doing now?
Also it might be important to know that when flashing via USB on a 64-bit machine the RUU program will give you an error about not working on a 64-bit computer. Just ignore the error and click ok, it will pop up a few times just keep hitting ok and it will work. That error pops up even though it's false.
when i first tried flashing a custom rom, i extracted the downloaded file and when i clicked on the ruu i had the same error... i then tried just running the downloaded file without extraction and it worked fine.
same thing happend 2 me Just run the RUU do not extract files!!!!!!!((-;
Barogi44, JFive1182 -- You are both princes among men.
The Unlocker will only run on the first auto-extract of the file. You cannot run the batch from the extraction folder afterwards, eventhough all it does is auto-extract the contents and then auto-run the batch file.
Out of curiosity... and being infuriated I went and tested this again just to see. On 3 other computers the same thing happened. I have no clue why it would bug out that way... or if it was written that way that's a pretty bad design.
In any case, someone should put that in the FAQ. You have to let it start the process from the auto-decompressing RAR, you can't start it again after the fact by running the batch file from the extracted folder. If it said this anywhere, the 3 guides I read never mentioned that (nore the unlocker's thread at ppcgeeks) so I didn't catch it.
Thanks again for everyone's input, and obviously JFive1182 & Barogi44 for actually letting me know how to make it work!
your welcome

Bump for emphasis. I had the same problem.
Tutorial said this: "Use WinRAR and extract both the files into separate folders,"
ONLY extract the NFSFAN rar.

zune if FUBAR

i have tried installing/reinstalling zune software on my windows 7 64-bit OS and every time it opens and then locks up my entire computer. i can't click on anything nor does ctrl+alt+del work at all. i have to physically restart the PC. this is obviously a big problem for someone with a windows phone. does anybody know what's going on? i wasn't having any problems for months until about a week ago.
They just did an update recently which is my guess, your problem. Did you reboot when you uninstalled, before you reinstalled?
How long do you wait for your pc to become responsive again? I have the same OS and same problem with Zune, I either wait for the pc to start responding again or ctrl-alt-del and eventually kill the process and start it again, which seems to fix it most times.

tried that. it is freezing everything immediately. i finally got to task manager and shut it down, but i cannot physically do anything in zune at all. any other suggestions?
it might sound weird but have you tried installing the 32 bit version of Zune?
there is no such thing as zune 32-bit. you download the installer and there is only one file that does the installation for any OS.

Run the installer in compatibility mode for XP... thats what my wife had to do on her laptop
Wow, I'm running Win7 64bit with no problems, have you tried doing a system restore back to when it WAS working? In case a system file got corrupt somewhere?
Clear out the Zune cache in your user profile. There's something in there that it's trying to load and locking up your computer. I'm not near my machine now, but it's somewhere in the AppData section.

i would give you a huge hug if you were around. i did a windows 7 search and found the appdata folder. clicked on microsoft and then right clicked on the zune folder and deleted all. i did not uninstall zune while i did this, but i did have it closed. after the appdata cache was deleted, i restarted zune and it works perfectly without any hiccups.
thanks so much!! i have never had problems with software so badly!!

true that, i actually went back to all 4 websites where i posted this question and made a point to paste in my resolution. one of the damnedest things about the internet is when people post problems on message boards, figure them out and then never post the answer.

Asus Zenfone 2 ZE551ML - tried to change firmware from CN to WW, huge problem.

Hi guys, I have a big problem with my Asus Zenfone 2 ze551ml. I bought it from china so I didnt have Google Play and I used to download every app I needed from Aptoide. But yesterday I decided to give it a try and change the firmware. I read every article on "how to", most of them were saying the same steps, so I started by downloading everything I needed, the WW firmware from asus site, the usb drivers, the adb program etc. Everything was going great, and I came to that point that you just have to send via adb the package with the WW firmware and... my laptop(which is an Asus, lol) stopped recognising my phone. Then I started reading tons of threads on how to fix that problem but nothing. I did everything.
Download the intel usb drivers for android- done
Manually install the usb drivers from Asus- done
Uninstall everything and trying one driver at a time- done
Usb debugging-MTP, all these things again and again- done
Tried every single usb cable and port- done
Tried 3 different computers- done
Wipe cache partioning and try all the above steps again- done
Wipe all user data back to default- done
And nothing.. I mean nothing, my phone is invisible to any computer. Is anything else I can do? What's left? To throw my phone away? Now everything in my phone is tiny, the app icons are tiny, the fonts are tiny, even the fb messenger bubble is tiny.. pls help me.. :crying:
my problems and solution for you
Hellooo, not all hope i lost...
Firstly the problem I have similar to you is that my ZF2 runs on CN firmware, which is the biggest struggle ever trying to find the only working APK app files, I was happily trying to install WW firmware (even though it had the playstore, as it was some sort of modded brand new phone front eBay) and I accidely pressed the button which wipes everything :') So I go 3 days figuring out how to make my phone start as another issue had arrised, I fix it with some 3rd party bootloader...and ever since January I've been living this almighty stuggle.
FUNNY THING IS...I KNOW EXACTLY HOW TO FIX IT...but my Acer laptop has an old version of the ADB driver which I cannot get rid of OR UPDATE and I have no access to another pc
As for your issue, by some miracle you read this...
1) make sure you're using a data cable (one that shows you're phone in the Windows library list n all)
2) if you're not seeing or hearing what I said...go in your phones setting punch the fu...I mean tap the "about " option right at the bottom 7 times, and you should now have unlocked the Dev Options...
Now, back to the settings list, press Dev Options which is above the about option, scroll down a little and enable "USB Debugging" press yes/allow...what ever the **** comes up and looks good and wulluh.
3) Now, if actually you've already done step 2 and have tried 3 laptops :0...try step 1 again
4) If you followed step 3s very very complex instructions to a level of hope that binning the phone or suicide are options then by all means set it on fire then throw it at your ex gf...if you have one...concidering you bought an Asus phone lol, mug
5) try this other thing that works but is just as hopeless by finding it on YouTube, searching "Asus ZenFone2 Flash" with the "past month" filter there should be a video with the thumbnail of an Indian man with a blue shirt and glasses, click on it...watch closely n stuff.
Hope it works out and that you found my profecional instructions helpful - Lewis

That's his issue, same for me, ADB does not show in device manager. Unless you mean installing the driver by right clicking on the phones name?

USB Mounting Issue - Work Around

Challenge / Background:
I recently rooted my Sprint HTC 10 to Viper v10 3.5.0 with SuperUser v2.74-2. This was my second root and I had a couple hiccups along the way that required me to re-flash during the process to make sure I did it right....ended up being something different. Everything works though as expected with the exception that I noticed tonight that my Windows 7 laptop does not recognize my phone. After multiple tries trying to update drivers on my laptop (can see it in device manager, but error) and that type of thing, I gave up and tried to work the problem from my phone. But, the only solution I could find online was regarding ensuring that the USB tethering option was on. Additionally, when booted to TWRP v3.0.2-6 I also was unable to mount my phone as a USB storage device.
Temporary work around:
I will still be looking for a permanent solution, and if anyone has ideas please let me know, but if others have this problem, an option that worked for me was utilizing "USB Tethering" in lieu of "(USB) File Transfers". In order to do this, I downloaded the below app from Google Play and followed the instructions. Its a little slow moving from folder to folder, but works as a temporary solution for the moment, or until I try to reflash again in case I mistakenly selected the wrong option in Viper.
I utilized the MTP-Alternative USB Drive application by ClearEvo located in the store for free.
Hope this helps.
