[HTC Inspire 4G] itzsnookums:
Ok so here goes, i have been getting pretty tired of being told that my phone sucks as a 4G phone and that it should even count as a 4G phone....So what i have been done is spend all night researching and testing ways to make the data faster...first thing i did is i needed to learn what HSDPA and HSUPA are....I found the answers here...http://en.wikipedia.org/wiki/Hsupa and here...http://en.wikipedia.org/wiki/Hsdpa.... what i found is that the stock inspire 4G comes stock set up for the release 5 version of HSDPA with max download of 14mbps.....now if you read all the column on the hsdpa page you will see the following....

Release 5	10	15	16-QAM .97	14.0---This is the stock set up

now common sense says that if i find a match that matches the HS-DSCH codes/modulation and the code rate...that category should work...right???

well after reviewing the whole page i noticed that there are two that can match the original class settings.....these two.....

Release 7	16	15	16-QAM	MIMO	.97	28.0

and

Release 9	26	15	16-QAM	Dual-Cell + MIMO	.97	55.9

now if you look at the perimeters of the categories you notice a few things....

First the HS-DSCH codes Match on all three.....=== 15

Second the Modulation matches.....=== 16-QAM

Third The code rate matches.....=== .97

Now the only things that are different between these categories are the fact that they are different releases and that they use MIMO or Duel cell and MIMO. So what i did is i went into my build.prop and i changed these values to see what kind of diffidence or even if it worked if i changed the values....Well i first tried the stock class 10 then i tried the class 16 then i tried the class 26.....there wasn't much difference between the class 10 and the class 16....they were both producing between 2-3.5mbps download....(tested using speedtest and att.com/speedtest)....Then i tried the class 26 and the results i got made me a very happy person i am now getting consistent downloads between 5-7mbps download....now tell me something why in the world is AT&T selling 4G phones that can deliver very high rates of speed but they make them so that they produce lower downloads then 3g devices????

I will be uploading numerous screenshots of the results that i have proving that these values make a difference....so try it, try changing you hsdpa values to 26 and see what results you get....

here is what your build.prop network values should look like.....

ro.ril.hsdpa.category=26---This is your download category

ro.ril.hsupa.category=7---This is your upload category

ro.ril.hsxpa=3---this enables the hsupa upload speeds

SCREENSHOTS USING THE NEW SETTINGS

HOPE THIS HELPS YOUR DATA SPEED....AND AS ALWAYS DON"T FORGET TO HIT THE THANKS BUTTON SOMEWHERE DOWN THERE UNDER THIS POST......​
[HTC Inspire 4G] trell959:
Thank you sir!!! I averaged 1 down in my room but that shot up to 3 down! Thanks!
[HTC Inspire 4G] itzsnookums:
Anytime, just thought i would help some people out....btw did you reboot twice???? you need to so that the settings take effect....don't know why but its what works...
[HTC Inspire 4G] trell959:
One reboot did it for me :)
[HTC Inspire 4G] itzsnookums:
Sweetness....glad its working for someone else then just me.....:)
[HTC Inspire 4G] scyr2355:
a noob question how do i get to the build.prop??
[HTC Inspire 4G] itzsnookums:
What you do is use a app called root explorer from you phone, you then select system then on the upper right corner there is a mount r/w, you select that the go to build.prop and it gives you a list of options, you select open in text editor then changed the values listed in the op....hope this helps...
[HTC Inspire 4G] yareally:
I hate to be a wet blanket, but true 4g speeds are what comes on LTE :)

However, it's good you found a way to maximize what you can get out of hspa+
[HTC Inspire 4G] itzsnookums:
True That....but its way better then it used to be....
[HTC Inspire 4G] shugga101:
What is everyone's current radio and ril as well as rom. This should help others who want to maximize their data speeds.

I am using the miui lastest update from the 23rd. And radio 12.59.60.26P_26.11.04.21_M

And ril HTC-RIL 2.2.0160HM (Jun 3 2011,23:41:59) and this is not giving me great speeds. I used es explorer went into my root/system/build.prop and changed the values to what was provided. I rebooted twice. I checked to see whether values are changed and they are. My speeds aren't as good as they were.

So maybe a different ril/radio combo could help or a dif rom?
[HTC Inspire 4G] Bobby.O:
First shot 5MB increase. Effing sweet thanx a lot this is amazing
[HTC Inspire 4G] heathroi:
4g speeds

Didn't see any difference in my neck of the woods.
[HTC Inspire 4G] matt3:
I think it actually slowed my phone down.
[HTC Inspire 4G] steezee:
Actually if you want to get technical LTE is 3.9G...LTE Advanced would be 4G
[HTC Inspire 4G] nhshah7:
You're all wrong. It is 4g. I'm right. Mwahahahahaahaha

gonna try this now. super pumped if it works!!

EDIT: *sad face* speeds went down after 2 or 3 tests. will keep this on for a while to see if it is just a network fluke. :\
[HTC Inspire 4G] Agoattamer:
Others have tried changing these values previously. There has always been mixxed results. Just face it. Depending on where you live speeds will be different. If ATT has your tower capped at 2M down then you are only going to get 2M down. Most get the same download and upload speed with 10, 6, and 2.
[HTC Inspire 4G] southygov:
Op, I went into root explorer and then system but there was no option in the upper right corner. There was an option for build.prop so I opened that, but was unable to edit the values. There was no way to edit the text for me. Tried the menu option, long pressing and so on. Any idea what it is I'm missing? Thanks
[HTC Inspire 4G] Agoattamer:
Root Explorer will allow you to edit it. Long press on buid.prop and select "open in text editor". If it says it is read only in root explorer then tap where you see highlighted up top "Mount R/W" and it will change to "Mount R/O" then you can long press on the file and try again.
[HTC Inspire 4G] southygov:
Thanks, but all it tells me is that my phone needs to be rooted. I'm not running a rooted phone so if that's the case than, oh well. But, if this can be done w/o a rooted phone than maybe there is something else I can try.
[HTC Inspire 4G] homeslice976:
Yes...you need root access to be able to mount your file system as r/w to edit these types of files.
[XPERIA X8 Q&A, Help & Troubleshooting] exebreez:
Hello,

Could anyone tell me how to change a xrecovery package like a rom or module to a CWM package, which could be flashed ?
[XPERIA X8 Q&A, Help & Troubleshooting] bxmx666:
yeah sure just search and you'll find it and install zip from x recovery

or you can have dual recovery check the multiboot thread
[Samsung Epic 4G Touch] Beejis:
Might have to return the phone until the October 7th announcement since this phone doesn't support Rev B. Sucks because I LOVE this phone, but I want it to be future proof, which by it not supporting Rev B it is NOT. The only phone out for Sprint right now that does support it is the EVO 3D.
[Samsung Epic 4G Touch] nstavr:
I agree with you. Very surprised that this phone would be released without Rev. B support if that is in fact the path Sprint decides to take. Guess we will have to wait and see what happens. Guess I will hang on to my 3D a little longer just in case!
[Samsung Epic 4G Touch] tenaciousj:
delete.....
[Samsung Epic 4G Touch] Beejis:
The Photon I believe DOES have rev B support if they do infact have the Qualcomm MDM6600 like the EVO 3D, but I can't get confirmation on that.

Very disappointed they would use an older chipset that isn't compatible with rev b....
[Samsung Epic 4G Touch] Dalmus:
Thanks for cutting costs to make that $200 contract price point, Sprint!

So now we have what was, arguably, the hottest phone in the world (besides the iPhone) and we're hampered forever by the For Now network, which loses area in the coverage map almost daily...

*sigh*
[Samsung Epic 4G Touch] Beejis:
Sadly I agree. I will be getting the Photon 4g soon, not only to compare and contrast with the E4GT, but also so I can at least have that until October 7th and see if that actually is part of Sprints big announcement.
[Samsung Epic 4G Touch] abrcrmdl23:
There was a story I read dont remdmber where that it said the evo 3d and the gs2 and the conquer have rev b support the photon was up in the air but I have both so either way I should be good.
[Samsung Epic 4G Touch] Beejis:
Also, funny how Sprint conveniently changes the trial period from 30 days to 14 when they release the E4GT then THREE weeks later they are making a 4G announcement :mad:....

---------- Post added at 06:54 AM ---------- Previous post was at 06:53 AM ----------

According to everything I have read, the chipset in the E4GT does NOT support Rev B, but the chipsets in the EVO 3D and the Photon 4G do (they both have MDM6600).
[Samsung Epic 4G Touch] Dchibro:
I made a thread on this very subject yesterday.

[Samsung Epic 4G Touch] abowlby:
So, does this mean the 3G on our devices will be rendered incapable? I get like 1.5-2 Mbps on 3G, I'm cool with that and I also live a 5 minute walk from downtown, so I'm also cloaked in 7-10 WiMax.

Could someone explain if this will make any difference to the way my device functions now?

Edit: Another question, if the ET hadd the 3D's chipset, would we be having the same signal woes?
[Samsung Epic 4G Touch] nate420:
I need hard proof... Not saying your lying but look at the 3d "1080p" picture and video recording advertisement misshap

unless sprint comes out and says it im not returning it... And if they go past my 30 days (I traded in the photon so I still have the 30 day thing) I will make sure im leg out of my contract for a obsolete radio in this phone (if that's the case

Phone scoop says it supports the 800 mHz band:

http://www.phonescoop.com/phones/phone.php?p=3301
[Samsung Epic 4G Touch] Beejis:
That it does, but what good is a BRAND NEW phone if it isn't future proof for the next 2 years (now that there are no more premier upgrades and assuming that is Sprints announcement obviously). I will wait it out for another week (literally) and see if there are any leaks to the big announcement, but I will be returning the phone come next week just so I can delay some more for the announcement.
[Samsung Epic 4G Touch] Vegasden:
Yes. And if you click on the FCC link you'll see the phone does, in fact, receive in the 800MHz band.

[Samsung Epic 4G Touch] jake21:
Are we 100% sure the epic touch uses the 6085 ? This link sez the chip # was covered. Did he actually remove the label ?

http://www.ifixit.com/Answers/View/64642/Qualcomm+QSC6085+CDMA+Processor
[Samsung Epic 4G Touch] BlueGoldAce:
But is that all that is required for rev b?
[Samsung Epic 4G Touch] strung:
Not sure. There is EVDO advanced which is speeds beyond rev B. I suspect with the SDR's on the netowrk vision they will be able ot do it.

The CDMA radio image on phones is a real time operating system that fits into around 22MB. (The wimax chipset also runs a real time operating system.) I don't see why these couldn't be upgraded with a flash to support rev B or beyond, or why wimax couldn't be flashed to run LTE protocol.
[Samsung Epic 4G Touch] Beejis:
I'll get a screenshot up myself soon but enter ##33284# and click on configuration.
[Samsung Epic 4G Touch] BlueGoldAce:
Would be nice if there was a sure way to know. The phone is not really worth keeping if they didn't even bother with updating the radio.
[Samsung Epic 4G Touch] Loki047:
I guess that settles that. Unless she was wrong.. (cue dramatic music)

I just got this back from Samsung.

You are now chatting with 'Keisha'. There will be a brief survey at the end of our chat to share feedback on my performance today.

Your Issue ID for this chat is LTK5640145207X

Keisha: Hi, thank you for contacting Samsung Technical Support. How may I help you today?

MATT: I have a question about the Galaxy S2 on sprint. Does this phone support EVDO rev b?

Keisha: I understand that you want to know EVDO is supported by your phone, am I correct?

MATT: Yes but i jknow it already supports EVDO rev A. I was wondering if it supports EVDO rev b.

Keisha: Thank you for confirming.

Keisha: Let me check the information fore you.

Keisha: Let me check the information for you.

MATT: okay thank you

Keisha: Would you mind if I place you on hold for 3 minutes while I pull up the details?

MATT: That is fine.

Keisha: Thank you.

Keisha: Thank you for holding.

Keisha: Evdo feature is supported by your phone.

Keisha: But there is no information regarding EVDO rev A and EVDO rev b features.

MATT: Okay thank you for your time

Keisha: I would suggest you contact our voice support team for further assistance.

Keisha: I don;t want to provide you with the wrong information.

Keisha: You can contact our dedicated Galaxy S phones voice support team at 1-877-EZ2GALAXY (1-877-392-4252).They are available 24/7. You will need to registered to avail 24x 7 service.

Keisha: It's a toll free number.

Keisha: You're welcome. Is there anything else I can assist you with?

MATT: I appreciate that and thank you again.

MATT: That will be everything.

Keisha: You are welcome.
[Samsung Epic 4G Touch] bl4ckcontact:
Yeah, I gave that number a call after I got off that chat and spoke with someone. He gave me the same response that Keisha gave you... I asked him if there was anyone else that I could speak to that would be able to confirm for a fact whether or not it supports rev. b. He said his product analyst manager would be able to, but he is on lunch. He took down my email address and told me he would email me with more information once he was back in his office. Here's hoping that he actually follows through!
[Samsung Epic 4G Touch] ace0603:
Okay I just got off the phone with Samsung Level 2 support. I asked 2 times to confirm that this phone supports EVDO rev b. Both times he confirmed that it does support EVDO Rev b. This is the best we are going to get.
[Samsung Epic 4G Touch] Dalmus:
The whole reason Sprint's 3G network has gone to hell over the past year or two is because the roaming agreements with AlllTel expired, and Verizon, the new owners, refuse to allow 3G data roaming, except at huge cost.

You might NOT be on your last 2 year contract, because, if I remember correctly, the FCC ruled that Verizon (cell carriers in general, actually) had to allow "reasonably priced" 3G roaming.

Verizon will fight it for a while, but then will probably end up compromising.
[Samsung Epic 4G Touch] BlueGoldAce:
What's level 2? Did he know what you were referring to instantly? Or did he seem clueless?
[Samsung Epic 4G Touch] ace0603:
He knew right away. And had an answear in less than a minute.
[Samsung Epic 4G Touch] Wizard220:
Well here is how my call went.

Called 1-877-392-4252 spoke with a Mr. Allen. He then asked me what my phone number was ( cell ). He then proceeded to register my phone with the Samsung Warrenty Program.

I then proceeded to ask the question if this phone supports EDVO Rev B or not. He did not know the answer and placed me on hold for almost 3 minutes ( yes I timed it ).

Upon his return and according to his data sheet it does NOT mention EDVO Rev B support for this phone. He had no other info regarding the Rev B support question I asked. He then instructed me to get in contact with Sprint to see if this support can be added by a OTA update.

So what do we have, we have a few different outcomes in the phone calls that were made. Guess we all will have to sit down and buckle up and wait until Sprint announces it.
[Samsung Epic 4G Touch] ericdabbs:
The only prevalent bug that I experienced was the silent call issue and yes it was fixed in a timely manner. To assume that the Epic 4G Touch is a perfect phone without bugs is ignorant as well. The question is how long will it take Samsung before they release and update to fix these issues.

You are wrong about the hardware limitation is obselete nowadays. If it can't support it, it won't be. That is like saying someone can take a EVDO chip from 2004 with Rev 0 support and somehow convert it to support Rev B. Sorry it just can't be done. If it was so easy to convert old hardware to future hardware then why would anyone buy the new stuff?
[Samsung Epic 4G Touch] 1BadHEMI:
Here's the funny thing about this whole situation. You are all acting like September 7th after Sprints announces there future 3G technology, magically they are going to run into the back room and flip a switch, and poof! EvDO Rev B is going to be turned on the same day. Its going to be MONTHS BEFORE it is implemented! There is a lot of backend work that has not even been started yet, and contracts are still being sent out for bidding. With that said, even if the EpTouch doesn't support Rev B, by the time its actually turned on in most areas, you'll be close to your upgrade. Hell, by this time next year, the SIII will be out and everyone will be jumping from the SII to that!

Bottom line, would I ditch this phone if it didn't support Rev B? Hell no! Again, the network is no where near ready to be lanuched, and by the time it does, if its still within my current contract term, I'll go by the next greatest out right just like I did for both my EpTouch and my wife's!

This entire thread is USELESS until an official word comes from either Sprint or Samsung. All this thread is doing is taking what is the BEST phone out at this current time and trying to trash it, for a technology that isn't even launched yet, and will take months to deploy!
[Samsung Epic 4G Touch] james33440:
Couldn't agree more....
[Samsung Epic 4G Touch] ace0603:
Was this the first person you talked to or did you ask for Level 2 support? This sounds like what the first person I talked to said. I thenm asked to be transfered to a higher level of support. He transfered me after about a hold of 3 minutes. Finally someone answeared and he knew right away what I was talking about. After he confirmed that this phone works on rev b. I assked 2 more times "So you are confirming that the Epic Touch 4g Samsung Galaxy S2 works on E V D O revision B." Both times he said yes. Take it as you will. I know I did and I still don't think this is what the anouncment is for. I just am sick and tired of seeing all of the Epic Touch forums flooded with this issue. Enjoy the phone as is or return it for a lower end phone if you don't like it. How about the Iphone 5 anyone?
[Samsung Epic 4G Touch] Wizard220:
Not trying to trash it at all. I have so stated in my posts that I adore this phone and yes I do think its the best thing out right now. But the fact of the matter is this, all I want is a stright answer if this phone supports Rev B and that is all.

And yes I do relize that it will be months to even over a year or more before this system is deployed and activated.

But again if this isnt such a big deal then why not just come out and say yes or no to the questions ask regarding this phone.
[Samsung Epic 4G Touch] psone:
I think most of us who are fretting about this are in a 3G only city/area and the hope of rev. B is a big reason we bought this phone. Our cities were left out of the WiMax expansion and we most likely won't see true 4G for 24-36 months. Rev. B was just a little more bandwidth to make life on these beautiful phones bearable. Think how it is to have a nice screen, fast processor and then wait and wait for a simple web page to load up.
[Samsung Epic 4G Touch] bl4ckcontact:
EXACTLY. I'm getting a variable speed test result anywhere from .03 Mbit to .3Mbit on a good signal... with full bars. This is flat out unacceptable.

An Online Chat With Sprint Just Now....

Pay attention to the last bolded line of correspondence....

3:16:46 PM : Connected to sprint.ehosts.net

3:16:46 PM : Session ID: 3770313

3:16:46 PM : Jim Fenton: Initial Question/Comment: As we now have only a 14 day window for returns, I have a question which I need answered. Is the Epic Touch 4G able to fully utilize EVDO REV B with all of it's benefits? It appears that the Qualcomm chip in this device is an older chip and the specifications do not show it being able to supprt EVDO REV B. Could you get me a definitive answer please?

3:16:56 PM : Joan P has joined this session!

3:16:56 PM : Connected with Joan P. Your Reference Number for this chat session is 3770313.

3:16:56 PM : Thank you for contacting Sprint. My name is Joan P.

3:17:07 PM : Jim Fenton: Howdy Joan :)

3:17:26 PM : Joan P: Hi Jim

3:17:26 PM : Joan P: I am happy to assist you with locating that information.

3:17:31 PM : Joan P: Please hold a moment while I access your account.

3:17:36 PM : Jim Fenton: No problem

3:19:26 PM : Joan P: Thanks for waiting.

3:19:50 PM : Jim Fenton: Certainly

3:22:11 PM : Joan P: As per the status of the phone that we have:

3:22:56 PM : Joan P: The phone has the following Processor/Chipset: Samsung Exynos™ 1.2GHz dual-core processor / S5PC210 that will support (EVDO Rev A.)

3:23:36 PM : Joan P: That is the 3G download speed and peak download speed will be 3.1 mbps.

3:23:45 PM : Jim Fenton: So you have no indication that it can utilize EVDO REV B?

3:24:46 PM : Joan P: There is no update regarding the REV B. However, I am sure about the REV A and that is the latest update regarding the phone that I have to share with you.

3:25:28 PM : Jim Fenton: I'm not looking for any information regarding updates and I appreciate the fact that you folks can't give them out till they become reality anyway.

3:25:47 PM : Jim Fenton: What I really need to know is if the phone has the hardware to support EVDO REV B?

3:27:16 PM : Joan P: No, the phone is not with the hardware configuration that will support REV B.

3:27:28 PM : Jim Fenton: OK Joan...

3:27:35 PM : Jim Fenton: Thanks for the information.
[Samsung Epic 4G Touch] Rattor:
Maybe because no one official has gotten wind of the fact that people are asking this question? Do you expect them to just make an announcement with no prompting? "Oh, btw, the E4GT supports EVDO Rev B. That is all." Who do you want to come out and say yes or no to the questions? Who are we asking that has the power to send out a press release to this question that a few tech heads are asking?

The fact is this isn't a huge deal to anyone except us few here. No one knows we're asking these questions. No one thinks this is an issue at all. It's like you expect either Sprint, Qualcomm, or Samsung to automatically know that we here at XDA are asking these questions and for them to announce the answers that Wizard220 is demanding. Calm down. Take some breaths. Wait for an official announcement one way or the other.

---------- Post added at 02:35 PM ---------- Previous post was at 02:33 PM ----------

No offense, but that lady is probably going only by spec sheets that she's given. It makes no mention of Rev B, so in her world, the phone has no Rev B support. Period. Sprint 1st level online chat support is hardly the most reliable of sources for tech info.
[Samsung Epic 4G Touch] jfenton57:
I don't disagree with you at all. Somebody somewhere must know for sure if the phone does or doesn't have the hardware to fully utilize EVDO REV B?

Question becomes, what is the correct source to get this information from?
[Samsung Epic 4G Touch] Wizard220:
Ok then please point us all in the direction of any spec sheet on the net that says the QSC6085 chip supports Rev B.
[Samsung Epic 4G Touch] jfenton57:
I'm going to ask a dumb question as I honestly don't know the answer....

When I look up the specs on the Samsung 1.2hgz chip, it states that it supports EVDO REV A.

Does that by default mean that the main processor can't support EVDO REVB?
[Samsung Epic 4G Touch] Dchibro:
I'm not sure where you're seeing anything about EVDO on the Exynos 4210 SOC. Cellular voice and data capability is handled by a separate chip in this phone.
