Hi,
Just looking for some advice on a problem with my HD2. Am having significant problems with the bluetooth, which I suspect may be caused by a fault in the phone.
Bluetooth works, but the speed of file transfers is incredibly slow. Have performed different tests, using different PC's, and different ROM's with essentially the same results.
Bluetooth file transfer speed varies, depending on the device it is connected, between 7-60 KB/s, and fluctuating wildly. The same test using a Nokia phone and same PC's yielded file transfer speeds between 90-110 KB/s. This slow performance seems to degrade the clarity of sound when using a bluetooth headset (Nokia BT-214).
I have used the latest standard HTC ROM, and the latest of Dutty's ROM's, and both produce essentially the same result. I have read that there are some problems arising out of the Widcomm stack, not working as well as the MS one, but have seen no posts indicating anyone having as significant problems as I am having.
Advice please.
I just tried and with some little tweaks from "HD2 tweaks 1.3" program, I have a sustained 110 to 120 KB/s. You can try that
Thanks for the reply, and help attempt. I tried this, and unfortunately it did not make any improvement, still very slow.
I get 90-120kB/s too, without any particular tweak.
What would be interesting to know is whether you have a particularly active WLAN in the area, wireless security cams or such around you...
As an example, if I start a BT transfer ftom the PC to the phone via BT, and then start transferring a big file from my laptop to my PC via WLAN, transfer speeds on BT will fall to 40kB/s or so.
Thanks for your thoughts on this. Just tried a file transfer with WiFi both enabled and disabled, produced exactly the same in terms of file transfer speed: 50 KB/s.
This is incredibly frustrating. I have sent a message to HTC asking them if they think it a phone fault or not, and am awaiting a reply.
Dear all,
as my Galaxy S was plagued by issues like slowdowns and GPS "jumping" I have decided to try out the JF5 firmware. It seems that the firmware indeed includes important bugfixes — GPS is way more precise now and slowdowns are basically not observable anymore.
Unfortunately, the new firmware seems to fix another bug — a bug I actually liked. I am talking about the "USB-debugging-bug" which allowed my Mac to recognize the phone as a USB storage device. After the update my Mac Book Pro is unable to either mount the Phone or see it as a modem.
Did any Apple user experience similar issues? Any solutions? Any alternatives? Any good Apps which would allow me to access the internal storage?
Thanks for your help!
Update: solved the problem. Apparently my Mac was to blame. I reloaded the USB kexts and it started working again. Sorry for false alarm
Hey guys.
I live in Australia, I have the Telstra-stock i9000T. Ended up rooting it and putting on the NZ "Telecom" version with HSDPA / NextG 850Mhz capabilities, because Telecome released 2.2 Froyo MUCH MUCH sooner than Tesltra bothered to do.
The phone has been running great ever since - and I only mentioned the above because before rooting it, i was able to watch 2GB-sized files of .mp4 videos without a hitch...now it seems i can't even TRANSFER them onto my device.
Whether i connect the USB and try and connect via 'mass storage' or 'kies' and copy/paste the video to my SD card (Sandisk 16GB SDHC, bought new), it just says it cannot copy. i USE Win7, if it gives me a timeframe to transfer (usually doesn't, so hard to tell if its working or not), it says 11-12 hours, which is insane, as at work, can take between 20-30 mins MAX to transfer a 2-3gb file. The audio file attache dis H264, or a common playback that IS normally compatable with this phone, so thats not the issue...
What its now doing, which it didn't before when i was able to transfer and play without a hitch - was it now asks to transfer and CONVERT to a playable format, or just transfer over knowing it may not work? No matter which option i select, it wont transfer over. I am still able to transfer smaller files, pictures, etc. Has anyone encountered this problem, or can suggest a way of fixing this?
PHONE DETAILS (after Telecom NZ flash)
Firmware: 2.2
Baseband: I9000TDOJP1
Kernel: 2.6.32.9
EDIT/UPDATE: Put the SDHC card into a USB reader, plugged into PC and transferred mp4 video files that way - the videos are recognised and play to perfection, so i am led to believe its an issue with Kies or the transferring of certain files to this phone when its turned on and in USB mode. The USB cable is the one that comes with my original package so i really dont know what the problem could be, i've only recently flashed a new copy of Win7 Ultimate 32 bit, so i doubt that comes into play... any thought?

Anyone at all?

This is happening to me, now I am unable to flash and my phone is messed up now.
I havent got to that point myself, probably should look into this next. I'm selling it shortly in favour of the SGS2.

No one else?
I would dump/remove kies and then just install the latest/correct USB drivers, unless you have a real need for kies?
I would turn on USB debugging and connect to my PC that way. It's much simpler than trying to go via Kies (which I don't bother using any more).

I might uninstall and reinstall the drivers, the problem still occurs whether i use Kies ir not, i prefer not to use the software either - its easier directly dealing the the files in question.

Has anyone tested how fast files can be transferred between the N7 and a PC over USB?
I guess I'd be mostly interested in write speed to load the device up before taking it somewhere. The OTG stuff sounds cool for long trips but most of the time I will probably just want to put a few GB of things on the internal memory.
I know the wifi will max out at 3 MB/s or less, I'm hoping the USB can do at least 10 MB/s? That is what I can effectively do currently with my SGS by using a card reader to load up a class 10 microSD card, which obviously won't work here.
How do you know wifi will be 3MB or less?
Hoping this is faster than the Playbook, which was around 5MB/sec or so. Not that big a deal at night but was a bit of a problem when trying to quickly load videos on it before leaving for work. iPad and A100 were much quicker to move videos onto.

It is only 20 MHz channels which means no higher than 65 or 72 Mbps theoretical which only delivers about 25-30 Mbps real throughput. Could get maybe 3.5-4 MB/s but no way higher than that.
No mobile devices are getting 40 MHz 802.11n channels until they start using Broadcom BCM4334 or similar wifi chip, the BCM4330 that the Nexus 7, Iphone 4S and Ipad 3 are all using doesn't do it, so I'm skeptical that anyone gets more than 3-4 MB/s over wifi with any of them.
So far... Way slower vs. Galaxy Nexus (via adb push)
bump...
~3000 KB/s vs ~1000 KB/s
Pushing the exact same file (MP4).
Anyone else getting less than stellar USB transfer speed performance?
certainly not a scientific test, but when transferring a 350mb MP4 to my phones class 10 msd and then also to the N7, it seemed faster on the N7.
I didn't time it or anything
seeing this thread got me curious though. Maybe i'll test it out this weekend
I seem to be getting about 1.25 MB/s via adb push, using Ubuntu on my PC. Is it just me who's getting such a slow speed?
And MTP mode is weird.. I mounted it with $ mtpfs, and I copied my whole old /sdcard/ directory from my Transformer to my N7. It took a loong time.
And then I copied my music folder, 1.9GB or something.. and after another loong time, I went to my MIUI music app [can't have anything other than Folder music apps ], and only .aac files were showing. I couldn't figure out why but all my .mp3 files [in 10s of subfolders] were dumped directly into /sdcard/ [instead of /sdcard/Matt/music/*/*/*].
Anyway, does anyone know why I'm getting such slow transfer speed over adb? I can test the MTP's speed, but I doubt it's any faster. at all.
edit: I guess I should mention I am also not using the stock MicroUSB cable, I am using a generic 6' cable from Amazon. I wonder if that has anything to do with it? Maybe I'll try with the asus cord.
edit 2: check latest post, #8
MTP and ADB transfers are generally slower then using USB Mass Storage mode (which I guess is gone on newer devices and Android OS's), but the exact reasoning for this I don't know.

I wonder if it's possible to enable mass storage mode somehow? preferably without flashing a new rom..
Anyway.. Okay. So I was surprised to find out, but I just did a test on MTP, [via mounting with mtpfs on linux] and I copied a file at 14MB/s with MTP instead of 1.25MB/s with adb push.
O_O
The weird thing is, cp says it's done copying way before it actually finishes. It also says it cannot preserve timestamps:
"cp: preserving times for `/mnt/Matt/05.The Three Days of the Hunter Job.avi': Function not implemented
Command exited with non-zero status 1"
So I cp a file to /mnt/Matt/ [/mnt/ is my nexus 7 MTP mount location], and in 10 seconds it says it is finished, copying 349MB. So I check with adb shell and $ du -h {FILENAME}, and the size keeps going up! Until of course, it reaches 349MB.
So anyway, it's good to know I can now transfer at 14MB/s instead of 1.25 MB/s.
But I really wish Android had kept the Mass Storage Mode, just as an extra failsafe mode [and for people like me who don't like the MTP jazz, I like Mass Storage Mode]... oh well
Something I have noticed....
I have tried different cables, adb push, Ubuntu, Windows 7, Debian, USB 3.0 vs USB 2.0 and get the same results with all those different variables.
The biggest problem seems to be with multiple smaller files, such as mp3's or the blobs from nandroid backups. With large files like movies, or bzip2/tar files I get pretty consistent 15-20/MBs on all my systems.
My suggestion if it's reasonable for your situation, is to tar whatever you going to send over USB then untar once on the device. Taring should only ad about 1-2 minutes to the total process, but will still be faster than waiting for ultra slow tranfers speeds. I don't recommend compressing, as this will ad a significant amount of time for not much gain.
My Problem:
Copying a Nandroid backup, the blobs folder has a lot of smallish files and when I tried to copy the folder to my Nexus via usb, I got a ridiculous transfer speed of 750 KB/s! That is ubearable for 800 MBs of data, when I tarred the backup folder I got my much nicer speed of about 15MB/s. For my situatuion I was looking at least 18 minutes to transfer the data. With the tarred file it copied in under 1 minute + 2 minutes ( tarring/untarring)=much hapier me
the easiest way for me to untar was via 'adb shell'; busybox installed of course. Not sure if there is an app or tool for android that integrates extracting files like this with a gui format, that would make this even easier...hope this helps a little

I've have the same "problem", if you can consider as problem...also with my old N95 and the micro sd card copying a backup I got ridiculoas speed...so i'm not surprised very much...
However, copying normal files like mp3 pdf etc i reach the max speed of 15 MB/s...

700KB/s USB speed is actually a problem. MTP suffers from this problem. Phones/tabs with micro SD on older Android devices didn't Use MTP so you may not have had the same issue. I have never had anything transfer this slow on my older Android phones whether it was a lot of small files or big ones.

Well I was getting 1.25mb/s on big files too I think with adb (but my nexus burned in a house fire so I don't have to worry about it for now).

Sorry to hear about the fire,
Not sure why data was so slow. I guess I should add that I'm using Trinity kernel and system tuner to apply a couple sd tweaks. Maybe that has helped with my transfer speeds.

Hey guys,
I will return home in a few days and want to root my OP5 then.
What I wanted to ask is which ROM(s) is/are the best?
What is a must have?
And I have read that using Windows 10 causes problems. Is that true? Shouldn't I prefer using Windows 7 or are there fixes for whatever the problems are with Windows 10?
Thanks in advance
There is no real "best" ROM, you just have to try a few out and see what you like best.
As for potential issues on Windows 10, just try it out and see how things go. If you run into issues, search through these forums and I'm sure you'll find possible fixes. I haven't gotten around to even unboxing my 5 yet so I can't say any of this from personal experience...yet.
I'm currently on Freedom, with Boeffla.
As for the Windows 10 issue/myth - can't say I've experienced any issues. Phone connects to computer as soon as I plugged the USB cable in.
