[Q] extremely slow USB transfer speeds - Galaxy S II Q&A, Help & Troubleshooting

Hello,
Like the title says, I'm getting extremely slow transfer speeds with my USB connection ~1 Mbps. previously it worked fine got speeds like ~9-10 Mbps. but somewhere along the road this issue started occurring.
I've changed many roms, currently using CM10.2 nightly. did a clean install with complete factory/data wipe, reinstalled USB drives but still same issue. Also i use wondershare mobilego and it is also having trouble connecting, always says the device is sleeping.
Can anyone point me in the right direction as im lost with this one?

try a diff kernel like 'Dorimanx v9.41' and see if it helps u

Nightlies can have some pretty strange errors. But are you transfering big files or lots of small files? i.e. Transfering 300 files making up 1GB will take longer than transfering 20 files making up 1GB.

actually i've always been using CWM recovery. Previously it was some v5.x and when this issue occurred (dont know exactly when or why), later i updated to v6.0.3.8 . so i doubt changing kernel would help, but i might try it as a last resort as i dont want to waste too much time on it.

yes I know this one but even with a 2Gb file transfer rate is only 1Mbps max. it took hours to transfer my data to sd card, same on internal mem. i've also tried a lot of nightlies including CM 9.1, 10.1, 10.2 and various others, but still same..

All I can think of now is have you tryed different cables?

Could also be USB issue. Try a different USB port, preferebly the one on the backside of the motherboard.

I have / had the same problem with CM 10.1.3. After flashing the custom kernel Dorimanx-9.41 (http://dorimanx.shine.sk/ ) and setting the kilobytes to read-ahead to 1024 kB in STweaks (IO) the transfer goes from 2 Mbps to 15-20 Mbps.

[SOLVED]
Ok. so i updated the kernel to Kernel_Dorimanx-V9.41-[15-19]-[23-09]-JB-SGII-PWR-CORE . Now the transfer speeds are ok. 8-12 Mbps and wondershare mobilego can also successfully connect. It also comes with a lot of tweak options and display colors are much more vibrant now.
thanks.

Good News!
DorimanX-9.41 kernel is very customizable but I went back to original CM-10.1.3 kernel because my music stutter with Dorimanx-9.41 and CM in standby mode.

Upload speed after installing custom Rom.... Slower?

So, stock I ran the speedtest app and managed around 32 down on 4G - since installing a custom Rom however, it seems anything based on the .9 release, uploads seem capped at around 5. Anyone else have this problem?
Sent from my ADR6400L using XDA App
Ya my upload speeds were right around 24mbps stock. After root, kernal and rom i dont get above 4mbps up. Strange. Also speed test app says I'm closest to DC. Even though I'm in Florida.. could be GPS fail.
Sent from my ADR6400L using XDA App
Guys.. you arent actually getting those speeds. LTE does about 15 down, 5 up. The buffer on the phone lies about your speed because the file being sent is smaller than the buffer size. If you want a REAL number, tether to your desktop computer and run speakeasy.net

so once you root the packet being sent changes size when rooted??? i did a few trys before and after rooted at the actual speedtest.net not the app and there was a difference so im sure there is something else goin on

Something about this doesn't pass the smell test though - using the same app, same hardware with only the underlying framework changed the numbers it reports should be identical..... even if they are flawed and way inaccurate. I know in reality it isn't 30 something up, that's a little rediculous, however I would expect a custom rom to report the same error the stock rom reports, or if it doesn't have an explanation as to why it doesn't, and why the number it reports is more correct... it's just confusing otherwise. Thanks for the replies guys, it's been bugging me

poor data speeds

I got my vibrant back in september, and since then the data speeds have dropped significantly.
I remember being able to reach around 10-13 mb/s on wifi and around 4 or 5 on 3g.
now I'm lucky to reach 6mb on wifi, and 3g is rarely above 1.5/s
has this happened to anyone else? any tips on how I could fix it?

There are codes to change settings for your data settings on the phone, have you tweaked those?

Are you talking about the codes that you can see from using SGS Tools? If so, I haven't messed with those.
Only thing I've changed manually sometimes are the APN settings, since randomly the T-Mobile US one liked to disappear on me before. But I checked online and the APN settings are fine.
Which cm7 nightly are you using?
currently on #26, but it might be cm7 as a whole. i don't remember my data speeds on cm being as good as they were on Team Whiskey's roms, and seemed like stock jfd/touchwiz data when i first got the vibrant were the best.
any ideas?

[Q] SGSII Internet connection problem

Hey XDA
I've a problem with my SGSII.
I've tried a lot different roms like CM7, CheckRom, Oxygen, miui to find the perfect rom to fix my battery usage(my phone usally last for MAX 1 day, even on low usage. (Is this normal??, my friend get like 5 days with his SGSII)
Anyway, on pretty much all of the ROMs above I've occurred a problem with my internet connection - When my phone is idle for a while I looser internet connection and then I have to restart my phone to fix it.
Anyone with similar problem?
Is my phone defect?
Any way to fix this?
Thanks in advance.
This is my first thread on XDA, I hope I did it correctly (I've checked out suggested threads btw)
the problem with the internet connection is because of the signal is not resetting itself. You can use signalreset (market) app as a solution otherwise flash a stock firmware ROM from sammobile and see whether the problem is solved!
My Wi Fi stops working the same way too. All I do is that I reconnect WiFi from the notification bar.

Thank you for such a great and fast answer!
I will check out Signalreset asap, however if it just en/disable flightmode I am not sure if it helps. Because when it happened I always try en/disable flightmode, without luck - I have to restart to make it work :-/
Soo... it's a generel failure in some deeper laying hard- or software, that's not dependent of the generel software-version.
I'm starting to hate my phone, as it is loosing connection again and again, but only after updating to KI8_NEE. There has not been ANY problems with KI3_NEE, which worked perfectly and rocksolid - and solved the same problem from the previous versions... KI8 may be smoother, but i prefer stability over this generel failure (there's a lot of generel faults, not just lost data-connection).
If that the case, i'm going to smash this phone, or put KI3 back on it... i have been so happy with it, but after upgrading to KI8 - i'm starting to develop a hate-relationship with it...
My old HTC might be slow - but it is dead-on stable...
After trying the signalreset it still doenst work properly.
Any suggestions?

What baseband are you on?
I'm on XWKI1 on AT&T in south Florida and my connection is rock solid now.
That was not the case when I first got the phone with the factory ROM and baseband.

No I dont, I've tried Juice Defender but it didnt help my battery life so I uninstalled it..
I've tried a few days with the stock unrooted and the problem didnt occur, however the internet was still extremely slow, even when I had full signal.
Is there an application to boost signal/speed and/or fix problems?

[ROM] Unofficial RandomROM Falcon v 1.1

If you want to try another flavor of ROM based off of ICS 4.04, AOKP MIlestone 6, try this:
RandomKing's RandomROM Falcon v 1.3
I like it and would not have known about it except that it showed up as a compatible ROM in GooManager.
NOTE!: I AM NOT THE DEVELOPER, NOR CAN I ANSWER ANY QUESTIONS ABOUT IT. I'M JUST INFORMING THE COMMUNITY IT EXISTS.
I found it the same way and have been using it myself for about a week now . no problems the only thing i changed were the e-mail and contacts back to standard rather than inverted black and white . plus i like the ability to have sound with my boot animation an option that is not available with the regular Nightly or the AOKP&CM9Remix by SGA .
How does it compare to the other roms in term of smoothness and performance?
Just flashed this rom and I'm liking it.
Trebuchet should be taken out though if Nova launcher is included.
Ran AnTuTu OCd @ 1.78ghz and got a score of 7317 and the highest FPS on the men in armour was 57fps
After having the various CM9 nightlies I am trying out the 1.1 version of this ROM. So far so good... seems pretty snappy. I haven't found anything that doesn't work so far. I chose Nova as the default launcher (seemed to have come with Nova pre-installed?).
Question... how do you change the default email color scheme. Its hard to read. Thanks!

Give this ZIP a try in TWRP/CWM:
http://db.tt/Dp221gce
It's a universal inverted Gapps that I use in most of the ROMs I install on the TP. If need be, you could always extract the gmail APK from the ZIP and push it to /system (after changing permissions, of course).
Let me know if this helps you out - I'm curious about this build - and I would like to give it a go, too.

Thanks! The universal inverted GAPPs works great and solved the problem. Many thanks.
Btw, so far I have been able to run all apps I would before using the CM nightlies including youtube , Netflix. No lag at all between screens and everything things to work as fast as before. I believe the dev focuses on battery length but so far it seems to last about the same as my experience with most of the more recent nightlies. Unfortunately wifi is also about what I experienced under CM9 (and weaker than webOS).
I will stay with this a while and see if it continues to be problem free and if any apps have a prob under the new ROM.
Again, thanks for your help, and let me know if I can answer any more questions.

Goo is a decent website, and you can go to my space to download. Goo Manager can tell you when a new version is released, which I find pretty useful. 1.1 is currently the newest version, and I've finally updated the website to reflect the proper link. I agree, Goo Manager itself is a little slow and its easier to download straight from the site. I will not provide support outside of my page for this particular rom, but seeing more than 250 downloads on the latest version, I will continue to improve the rom whenever I can.

I gave this try and found out compared to cm9 9/30th it does have a higher battery drain while asleep.. ~-800 vs -45 avg
Both roms connect to my WiFi 5ghz
Other than that the rom seems decent to use if you don't mine the heavy battery drain.
Understand that I clear everything after I made my backup to try the rom, so to say it was on a nearly clean install.

Interesting. I just checked mine and while asleep mine ranged from a low of -43 mA to to an outlier high of -74 mA, and most of the between -46mA and -48mA. Once I wake it up it varies greatly... -122mA to -820mA, but I am guessing that is dependent on what I am doing (I was watching a lot of Clapton and Knopfler YouTubes) . Are these numbers more in line with what you were thinking RandomKing? Any other battery stat I can provide that might help?

Using Battery Monitor app. When I switch to %/hr state it appears to fluctuate between 0% to under 2% loss/hr. I'd guess it would average to around 1% per hour.
Btw I am pretty happy with battery on this ROM, not as good as webOS and definitely less than iOS but pretty good for Android and I think better than CM9. Now, if I could somehow I improve my wifi I'd be golden...

One thing to check, under wifi > advanced > wifi on all the time only when plugged in. Another easy and cheap fix is downloading RootDim from Play Store, which allows you to lower screen brightness way lower than stock. The TP has a very bright display so lowering it down to below 25% is still plenty bright. There are lots of other battery tweeks I am sure including apps that automate the process but the two I suggested are easy. Hope this helps!

if i put it a little bit further, it is dropping to 0 ( not in range )
i usually put it on my computer desk which is aprox. 50 cm from the router and it only gets one bar wifi signal.
when i first bought this phone, at my room get 3 to 4 ( full ) signal strength, now its not even in range.

It is kernel related problem, if it is not gaining signal in any of the kernel you are changing, then that should be a hardware problem. Give the phone to repair...
