Turn HSDPA mode off and "pure" 3G mode on

I've recently bought the HD2, former I ownt the TyTn II and th XDAII
Now I want to turn off the HSDPA data connection (The "H" icon appears in the taskbar) I only want to hav a "normal" 3G connection!
Can somebody help me to finnd the switch in the settings to do this!?
Cheers Chris

Why would you want to ruin your cellular data connection?

Connections > Advanced network...disable HSPA. Soft-reset.

why turn off the thing thats going to allow you to have much higher speeds?

1) If you're in an area with low to nonexistent HSPA, having it on will drain your battery immensely as it searches for signal as you're surfing.
2) Similar to #1, using EDGE or 3G will reduce battery consumption because data pulling will be less intensive.
3) if you're not doing a lot of streaming and only use your phone to read websites and/or update stock/weather/twitter/fb/etc, having it on EDGE or 3G produce similar results.
I can't believe I'm listing the options as to why the original poster would want to limit his data to just 3G, but I guess I shouldn't give too much credit to the kind of people who post on this forum.

HSDPA - isn't it working only under umts? I have EU HD2 - GSM model, should I turn it off permanently?

uhh what? Do you have an "H" symbol on your HD2? If not, then there's nothing you should be worried about.

nor really an bump but
HSDPA is not very reliable once single levels get below 100/95dbm (or 2 bars some times 3 as it does not always update in real time)
other note if H is enabled the phone will waste time trying to connect to an H signal that's not there or mite just be in range but is not
on my HTC HD1 the phone works 95% of the time with UMTS basic 3g some calls are diverted, but with HSDPA it sucks more power and more of my phone calls get diverted on an daily basis (diverts to my other network phone when phone not connectible, not stating networks as its the phones Fault for connecting to an H or 3g when it should be on stepping down to 3g then 2g due to signal) norm as i use my phone for business use i leave the phone on 2g only so (my other phone that's an htc desire i norm do use the h on it as it tends to play nice and drop to 2g when it should normally)
any way my phone is not the issue as i have the benefit to disable H speed and use 3g (umts) on the htc hd1
i have the hd2 phone here right now but the phone keeps on insisting to stay on H when single levels are poor and resulting in txt'ing only working , forcing the phone onto 2g fix's the problem but norm 3g coverage is fine
is there any way to turn off H on the hd2 like the hd1 can or is there custom firmware that adds the option or adjusts it so its less aggressive

don't know why we are bringing this up from the dead, but I get great download speeds with only 1-2 bars of hspa (+). I can't see why I would want to turn that off.
And to the poster that says edge works fine for most things, most of my updates time out trying to update on edge.

i hate edge.

the thread was never answered correctly (users posting on how good H is over 3g but from where i am its not so good as its turning the hd2/1 into an iphone 3 dropping calls wise when 3g/H is enabled) also turns the phone into an oven compared to umts mode and phone only lasts about an day with H enabled (2-3 days UMTS, 3-5 days 2g/GPRS depending on use)
3g?UMTS {most reliable for 3g} > HSDPA > HSUPA think there is an H+ as well for 7.5mb support
2g> gsm/gprs is king for keeping signal levels (EDGE unknown as I never get it but should be the same as GPRS) as there are more 2g towers then 3g or 3g/H towers, not cost affective to upgrade them all to 3g
one thing i not done yet is update the phones firmware as its still running on an 1-2 year old os this HD2 (uk t-mobile), the radio on it is 2.04 as well (my HD1 is 2 years or older) some one did post that it is in settings > adv network {was an older post that i found on google} that is missing on this currant HD2 phone i have
Most of the UK networks have not upgraded to edge around where I am so its GPRS or 3g/H

Some ROMs have the Advanced Network control panel applet in Settings/Connections where you can disable HSDPA and HSUPA.

I believe the relevant registry setting is at registry key HKLM\Software\OEM\RIL - DisH (Where a value of 0 disables HSDPA/HSUPA, 1 enables HSDPA and 2 enable HSDPA/HSUPA, reboot needed)

That was very useful comment I try it when I get back home later on (should really update the firmware as well the HTC touch flow is quite unstable on it)

i dont know where the problem is.
start -> settings -> connections -> advanced network.
there u can choose "disable hsdpa / hsupa"
bling, u got no H anymore..
if u use sense, u have to go via the windows settings, u cant change that in sense settings tab i think

i have to ring him on his G1 phone, if i ring the HD2 i get 2 things that happen its not connect (5 secs then the peeps call not conencted) or he answers it and it disconnects after 2 seconds
mite flash the device i never done it my self so mite do it on my HD1 first as mine is running on winmobile 6.2
--------------
i use an blackberry 8520 as an test at this time, was only £100 for it but i am missing the touch screen but like the idea of the 9800 having both screen and slide out pad but i prefer the windows phones input calendar points (hoping the win7 way be the same or like it)

that seems to have worked, did not seem to take it on the first reboot,was set to gsm only, set to auto was doing H still, still set to auto and powered down again and pulled the bat (prob did not need to) no h any more phone has constant 2-4 bars now on 3g (before 1-2 bar or drop call, on H if the phone was picked up 4 bars idle) can use phone and internet (was an fast call test was stable an clear not breaking up) should also stop it turning into an oven as well (as my HD1 does with H enabled), 3g is fine with opera as it has the turbo feature so web pages load fast still
give you rep if i could
i am not new to these forums but i have not done any messing with rom as my HTC HD1 one is currently just an unused PDA so i will have an go with it just need to look at the updating guides (need some class 6 sd cards as well all the ones i got are class 2 and are bit slow) if
once i have played with my hd1 i update the HD2 as that is an active phone (but needs updating on both phones as the default htc touch flow is an bit of an ram or cpu hog making the phone unstable, i disabled the touch flow on my hd1 as preventing phone call answer from working after 2-3 days as i needed it for business use but i like the default windows mobile layout anyway but i also like the htc layout when it works but must work all the time)

HD2 Handset or 3G Blackspot?

Right. You might remember I had connection issues with the HD2. I sent it off for repair, and it came back, but now displaying "3G+" at the top. This was super fast and everything was working fine. Now, all of a sudden it has gone back to 3G that is REALLY slow! Now, I see other people are having this problem. According to Vodafone, I am in a 3G blackspot and there is nothing I can do. If this was the case, I would never receive 3G+ in the first place, which they just ignore when I ask them about it. Could it possibly be the phone? I personally think Vodafone are just messing me around

Only 1 view? Any reply would be appreciated, this is an ongoing problem for me...

Edited : Was being a fool

Just because people look at it it doesn't mean they are going to have an answer i have seen some threads on here go unanswered for the best part of the day until someone comes on-line that actually has an answer, so just give it time, not every member knows what everybody else knows, that's why its a forum for people to club together and help each other out.
rant over

Oh ok, I'm sorry

Ok, so now Vodafone are ignoring me, which is just great (pfft). I would appreciate ANY help if there are any tips as to any procedures I could undertake. The HSDPA I was receiving just cut out the other night, and won't budge from 3G any more, not even to G or E, which is kinda annoying.

Have you tried it in a different area? You'll not get HSDPA coverage everywhere - that's normal. The way you're talking, seems like you're just sitting in your house testing it.

Of course I've tested it elsewhere. What you need to understand is though, I was receiving HSDPA full in my house for a good few days after I got the phone back from repair, now its just gone. All of a sudden, gone. I try doing the network selection process again, and the 3G+ flickers for a millisecond at the most, and then disappears. I don't know why this is happening, I used to get brilliant HSDPA connection wherever I went in Preston

Just to give you guys a glimpse of EXACTLY how bad the connection is, I ran a speed test on my phone via speedtest.net. Here are the results:

What is wrong? that you're getting as-expected 3G speed (.38mbps is the equivalent of 384kbps 3G standard) or the fact that you're getting a 3G+ symbol but are only getting 3G speed? Just because it's showing 3G+ (im assuming that it's similar to HSPA) doesnt mean you're at the optimal cell distance to receive it. It may be VERY POOR in your case, so it bounce you down to 3G.

That's the thing, its not poor in my area. I mean, I don't think even standard 3G is as slow as I'm experiencing. A 12 second YouTube video taking a minute to buffer? www.google.com taking a LONG time to load, there's something wrong man. I feel like just selling this phone and getting a BB or something, I know the connectivity will be strong with that.

How do you verify? Do you have another vodafone nearby that you can test out?

That's the annoying thing, I can't test out my SIM in another smartphone, as this is the only one I have. I have however tried another SIM in my phone and there is the same problem. This is the reply I get from Vodafone eForum:
Hi Faz20,
If it was a site fault that was to blame for this before, then it's highly likely to be the same sort of problem again. Issues like this are rarely ever the fault of the handset.
I have checked the postcode listed in your profile, and can see there are three possible HSDPA sites around you, none of which are showing any open faults at this moment, so we'll need to raise a case to our Faults Team for this to be investigated further.
I've emailed you so that we can start this process off
Jon
eForum Team
What is annoying me is that they keep ignoring me when I say I was experiencing fine internet connection with smooth speeds, and it just suddenly cut out. They just change the subject ALL the time when I mention it :angry:

One more to remember: you have to consider the speed AND QoS as well.
Try another site, I'd google for visualvare my speed.
If you have poor quality of service (you have veeeery long ping) that means: your phone tries to download.. then waits.. then tries again.. and some packets are lost.... so tries again... and so on.

1699ms ping is quite a lot I imagine? As my puter is only like 0.6ms, but surely the phone can't have that big a difference. Is there anything I could do to lower the ping, I don't want to flash and cooked ROM's atm as I am very inexperienced and don't want to void the warranty.

Then you're simply in a 3G blackspot. I know it's disheartening for having an HD2 and stuck with ****ty data coverage, but that's what seem to be the problem right now. You have a seriously high ping coupled that with slow transfer speed would only dictate that you're not in an ideal area where 3G coverage is plentiful.

How would that explain that I was receiving fine connection speeds before? This is where my hair is falling out

Maybe you're hallucinating that you had fast connection before? Maybe Vodafone thought that your area doesn't deserve the bandwidth and thus prioritizing the 3G speed for other, more robust, cities? Or maybe radioactive termites have run amok on the cell tower, causing you to not get fast 3G speed?
Who knows...

Nah, I can assure you I wasn't hallucinating, I stay away from the Magic Mushrooms
I just think Vodafone are a bag of s*it. All my friends with the same phone on O2, Orange are receiving HSDPA all the time. Its stupid
I'm gonna phone up Vodafone today and kinda go mad at them. The last time I phone they "escalated" the connection, maybe the reason why I was getting HSDPA all the time, wherever I went. Now suddenly its gone again. Quick question for you guys, when your phone is on 3G Full bars, how is the speeds. Are they quick and rapid? Do Internet pages load quickly? etc. etc.

Ok, so what do I get told when I ring up Vodafone. I have bad 3G coverage in my area (blatant lie). When I ask how do I resolve this? Buy Vodafone Sure Signal, £50 one off payment or £5 a month. Great way to resolve a problem, try to sell me something else, another one of Vodafone's probably bullsh*t products. Its so frustrating, having to live with a stupid network provider with such a beautiful phone!
Can I cry on someone's shoulder?

please tell me what radios you guys are using to get such good 3G speed.

I curently run android on my leo and even tho i got h indicator in my area i barely can go above 1mb/s down. I didnt test it on windows tho.
I use stock tmo radio
Just did a test with a speedtest app
1.58 down
0.8 up.
Sent from my HTC HD2 using XDA App

are you serious? how is it other phone can go up as far as 8MB and we can barely get 1?!

Hold on there. First, the android builds that can run on this phone are known to get slow 3G speeds no matter what, compared to what they should be in that location. nomadwgk would get a considerably higher speed if he was testing it through winmo.
Now, your speeds don't look right, if you're in a well-covered part of the DC area. This phone can indeed get speeds all the way up to the 7.2Mb limit, I've had mine test that fast once or twice here in bursts, but I usually get around 3-5Mb avg. So, there's something preventing your phone from getting the speeds it should.
Has it always been this slow since you first got it? How many bars are you seeing when you test it? What method are you using to test the speed exactly? This info will help us troubleshoot.

Plus, how strong of a signal did you have? From what I gather, a 4 bar signal will outperform a 2 bar signal.

i don't know how you guys get such a fast connection. every time i test it using dslreports i only get about 100-130 kbs. on a 400k test. and that's on a strong 3G connection in the middle of the city.
Its says my RR Turbo gives me 339 kbit/sec 1MB test. wifi connections on android, :::checking windows::::

There's a couple of factors at play here...first, you'll probably want to test with another site that uses a larger test file. I recommend www.speakeasy.net/speedtest...it works in IE but not opera, but it's the best mobile test site I've found.
Second, I learned from a T-Mobile engineer recently that the HSDPA speeds are actually dynamic, and load-dependent. In other words, the higher speeds won't fully kick in until you're transferring a larger amount of data at once...otherwise you'll get regular 3G speeds (or less) while just pushing a small amount of data (like weather updates, etc). So, you may not be able to measure the full speed you can get, until you're transferring a large enough file. That site I mentioned above seems to use a big enuogh test file to get full-speed results from the network.

Same problem
i live in vegas by the strip so OF course its gunna be good service,
I have 4 bars on "H" some times it will change to "3g" but it will still have 4bars... and my internet speed is like not even close to a MB, i took your advice about higher file transfer so i hooked up my xbox to my internet through my phone it worked, but it was really SLOW!
how can i fix the internet speed.

I didn't assume you were using android, I was just letting you know his results definitely weren't indicative of what the phone is capable of.
I use the radio you'll see in my signature below, it may make a difference, I don't know...it's the only one I've ever used on this phone.
You might want to double-check these three things:
1) Go to settings (WM settings, not Sense settings), and in the "connections" folder, choose "advanced network". Make sure "Enable HSDPA/HSUPA" is selected on the first tab there.
2) Also in the connections folder, choose the "connections" icon. Choose "manage existing connections" under the "T-Mobile Data" heading. On the "Modem" tab, make sure the T-Mobile Data connection shows "epc.tmobile.com" under the "Number" header.
3) On the Proxy Settings tab there, make sure "This network uses a proxy server..." is unchecked.

[Q] mobile network connection failed on wcdma, but works on gsm only

hey all, i've been a longtime lurker of the xda forums and always appreciated the fantastic work everyone here does. i searched the forums for this problem but saw many discontinued threads with no answer which is why I'm bringing it up (apologies if i wasn't thorough enough) .I was running the latest iced glacier rom 1.1.6, i checked that thread but found nobody with the same problem, making me think it was most likely my mistake and not a glitch in the rom. i was running wifi all day so i didn't notice until tonight that i can't connect to the mobile network when set at the "auto gsm/wcdma" and "wcdma only" setting, and only connects to "gsm only". its only when i connect to "gsm only", turn on mobile network and then go to the settings and select "auto gsm/wcdma" that it will connect me to 3g data . everything else gets me a "connection failed". I punched in the APN to no avail. I'm glad i found the way around the problem but I'd rather not have the problem at all. i did a factory reset and put the APN again to make sure, but still the same problem. does anyone have some insight into this problem and can help me? much appreciated

Hmm weird. Same thing happened to me today but it happened to me a different way. I was running CM Nightlys Build #3 and decided to do a nandroid that was from 2.x. After doing that Nandroid i ended up getting into a bootloop. So i figure okay, i'll just wipe everything and reflash CM since it was in my internal SD. Everything booted up fine but then i had no access to my data. Couldnt even connect to wifi. I then tried to go back to stock by installing the Pd5.img thats in the develop. forum and it returned me back to stock fine. Now my Wifi works but the data on my phone is still broken. I try to check and uncheck the Mobile Network and it just keeps saying Connection Failed. What do i do?

This is weird but I must live between several towers because I have a solid 2-3 bar H signal but my phone will drop to E aka edge at times and phone download speed takes a nose dive.... however if I change phone settings to connect only to wcdma the speed stays constant and super fast...
I have only noticed this happening at my home and no place else....
Anyone else ran into this?!

yes, my phone connected to data today LOL. damn that sux, i stayed up an extra 3 hours till 8am when i only usually stay up till 5am. almost made me late for work lol. data connects fine now but s is still on. maybe i'll re-root and then retry it to take it off. i need to return the phone and buy it elsewhere for cheaper.

I have been having the same problems even after changing out the phone. I believe it to be a problem with the software that runs the radio or the radio itself. It switches to different bands on it's own. I hope someone can address this with HTC or T-Mobile or both...

Why do you all quote the entire previous posts? It's obvious who you're replying to, so what's the point of that?
Anyway, I have somewhat of a similar problem, but haven't spent time trying to track the cause.. It might be related to wifi or maybe not, but at some random time after turning off my wifi, I will lose complete mobile network connectivity. No data will download or upload at all, until I reset my phone which seems to be the only way of fixing the problem.
I'm running Iced Glacier 1.1.5.1

Anyways, as far as my phone goes, its gone all day with no problem. Re rooted and restored so im 100. Never doubt that your local t mobile signal could be going through some maintenance.

Location, Mobile Networks, GSM vs WCDMA, etc.
I was about to post a new topic on this, but the nifty little Ajax monkey robot showed me this thread matched my keywords.
So I'm one of those d-bags that uses Facebook Places (Check-in). Not a lot and I don't frickin' check-in everywhere I go. I hate it when people do that. (Thanks for letting all of Facebook know you're not at home, so we can go break-in to your house.) I do use it though, as well as Yelp.
While I'm out, I'll go to check-in and it just spins its wheels - i.e. no Places load. I can be outside, clear sky and have GPS enabled and it still can't find my location. I noticed the same with Yelp, but Yelp actually errors out and tells me it cannot determine my location and prompts to go to my Location settings. Even with GPS enabled, Yelp still cannot determine my location. I noticed this here in Orlando/Longwood, FL and all the way down and through Ft. Lauderdale.
Obviously, if I enable WiFi my location can be determined instantly - e.g. Facebook Places finds it, Yelp finds it, etc. I'm not on WiFi all the time, so I don't really want to only be able to check-in at home.
I checked my APN and it has't been touched, it's at the default. I am on Ice Glacier, so I was willing to believe something could be different, but APN is correct. I also checked my stock ROM (Nandroid backup) AND my fiancee's phone, which is running stock (rooted).
I'm thinking it's got to be something to do with how my/our device(s) are registered on the network. So I look at the Network Mode and notice the default on my/my fiancee's phone is GSM/WCDMA Auto.
Just for giggles, I decided to knock it down to GSM Only. The radio restarts and then no H comes back - only Edge. I'm not just talking about the icon, I'm talking about the actual speed. Here's the cool part - once I went down to Edge (forced by being on GSM Only), guess what? Locations work perfectly now. Albeit a bit slower, but Facebook Places loads Check-ins immediately and Yelp is able to find my location now.
If I switch back to the original setting, the radio restarts, I get H back and for anywhere between a few minutes to a few hours, my location can be found. After a bit of time, I'm back to the same boat - location cannot be determined by mobile network.
I tried this on my ROM, my stock ROM and my fiancee's MT4G running stock - I can reproduce this 100% of the time.
I figured next, I'd try WCDMA Only...

To my surprise, location works perfectly now, 100% of the time. I switched to WCDMA Only last night and I have been able to use any/all apps that determine location by mobile network.
I will record a video of this, as again, it is 100% reproducible on multiple MT4G's and various ROMs. Our signal strength and network speeds in this area are amazing (Orlando/Longwood, FL). I consistently get 7-9 mbps down and never go below 6. My battery life is fantastic, as my radio is never switching between network types (note: In other cities, like in south Florida, battery can die super quickly because it's constantly jumping from Edge to H and back again).
Even better, when I use the Speedtest app, my server list no longer only has Atlanta or Washington, D.C. as my closest servers. I now have a ton of servers here in Florida, out by the coast, etc.
So there's my brain dump for now. I am not saying I have a fix, but I am saying there is definitely an issue w/ how these devices are registered on the network. I'm not saying I should be on WCDMA Only either, but I can say that in our area, my connection is perfect and now I have no issues with location via mobile network.
What the heck could the issue be? Why wouldn't the device be able to be found on the network when on GSM/WCDMA Auto? Edge does location flawlessly (when forced via GSM Only) and WCDMA Only does location flawlessly as well.
I'll do my best to record the video this weekend and show this top to bottom, but I figured I'd share what I could to see if A) this would help anyone with this issue and B) to see if anyone could shed any light on all of this.

Bump,
Did you resolve the issue? I'm having the same problem.

mine works fine on cm7 and set to GSM/WCDMA Auto. It might be the towers in the area, call TMO support and tell them your problem and your fix. They'll send a tech out there to check the tower

That's exactly what I was thinking, but I wanted to see others' opinions.
I'll let ya know what TMO says...

Its the towers. I am returning my mytouch today. Already switched to Verizon

GSM signal dropping and then disappearing?

I have had my HD2 since March 2011. It is unlocked, HSPL 2.08 and radio 2.15.50.14. Apart from the known issues with the Phone Canvas with later WM6.5 builds it has been fine. I have been cooking ROMs since my Wizard and then the Blackstone so I am reasonably experienced. I currently have my own custom build installed based on 5.2.23568.
For about a week now it seems to have developed a fault in that the GSM signal just drops off and then goes 'searching'. If I soft-reset the phone it will usually come back and then start to drop off again. If I disable the GSM radio and then re-enable it sometimes it won't enable immediately and might take three goes at the slider going green and then it asking for my PIN.
I have hard-reset, installed various different radios and recently re-flashed but the issue remains. I have also taken the case off the phone and ensured the 'touch' connecters are making contact with the antenna in the case housing. I ahave also reflashed te stock ROM and still the issue remains.
I have now reverted back to my Blackstone as it has become intolerable.
At the moment I have the Blackstone and the HD2 sat next to each other (both with Vodafone SIM cards installed) and the Blackstone has all 4-bars displayed and the HD2 has the 'Martini glass' searching symbol displayed.

Its an eBay purchase but is more or less immaculate - it isn't something I can get my carrier to repair if it is a hardware fault.....
Any ideas

First (not trying to be rude) have you swopped sim cards to ensure its not a sim issue?
Next (I read on you trying different roms) task 29 and reinstall a stock win mo rom, its been known that on occasions failures are resolved by doing this, if it works they put your rom back on.
sadly thats the best I can offer

Like above check sim card fully & network for issues.
I had a very similar issue on my old Touch Pro, signal would go weak & sometimes overnight would loose conection & I would need to toggle flight mode & then all would be ok.
I started think that was likely hardware after calling network & tech support was convinced my device, well turned out was network prob & only linked to that one sim & how it registered to tower !
So check it out well.
Also you could try padding the back of the sim with some tape in case it is a sim contact issue ... & perhaps flash a stock ROM from SD so everwrite HSPL,Radio & also rilphone.dll will all be paired as should be !
All long shots but not much else left ... Good luck ...

I have similar problem. The phone has weak signal and it looses signal on weaker spots where other phones have full signal.
I have HD2 from US and I am in Europe. Maybe I should put some Europe RAdio?
Also sound is very low.

Take CARE when flashing radios as non compatible versions on a US T-Mobile HD2 could result in HD2 paperweight.
My HD2 seems on par with other devices I have compared it for reception strength & I use it in some weak areas without issues.
Have seen a few posts on weak reception so it is either a particular SPL Radio & ROM combo is to blame or hardware issue if unlucky ...

Thanks for the replies it's much appreciated.
Firstly I have swapped SIM cards around (Vodafone Contract SIM & Vodafone Pay&Go SIM) and the fault follows the HD2. I think it has to be hardware or somthing 'unique' with my IMEI number and it registering?
It seems bizzare as I can sit here and watch the signal bars gradually drop off and then it go to 'searching' whilst the Blackstone just sits there happily with 3-bars and never budges.
I am unsure how to approach Vodafone about it as its my own phone (not supplied on a contract) and I think they would be able to give me some technical information as to what's happening with the registrations.

I would recommend try other network sims or a foreign sim & you can then connect to various networks (roaming) & test signal reception.
That is how I got evidence that it was my network (DTAC) at fault, luckily my network main Office is near my work office so I turned up & pushed the issue until they produced a technical individual with the required knowledge & gumption to help resolve the issue.
The Phone Techies are useless unless you get lucky & we are talking national lottery lucky here.
Chances of hardware are quite high too as a few threads along same issue as yours are around on HD2 reception.

It gets more bizzare - Since the Leo is just better than the Blackstone I decided to take both with me and keep the Blackstone as 'fallback'. Tuesday & Wednesday I worked in Hull and the Leo worked just fine. Went out to the pub last night and the Leo just wouldn't register. Over a period of about 15-minutes I tried soft resetting, taking the battery out etc but nothing. I gave up and left the phone on the bar whilst I was talking to someone and then 5-minutes later I get a text - check the phone and its got 3-bars of signal? I sent a text reply and then the phone seemed to be OK.
Today the phone has been in the same position at home where I took the photo above and its not lost connection all day (so far).
I don't know what to think but I still believe it isn't fixed....
