[HTC Rezound] Yura80:
I checked RF NV calibration with QXDM and it appears that the UMTS radio is not calibrated for 850 and 1900 bands. Most of the items have never been written. The solution might be to copy WCDMA_800_* and WCDMA_1900_* nv items from a similar fully calibrated device. That's what I'm going to do next.

Another interesting finding:

I have RF NV dumps of Bionic and Thunderbolt and they seem to be fully calibrated for WCDMA 800, 1900 and even 1700, unlike Rezound.

It's not surprising that Bionic is. We already known how to make it an "unofficial" global phone. So it's highly possible that GSM/UMTS can be enabled for Thunderbolt as well, by writing NV_RF_BC_CONFIG_I and switching mode in *#*#4636#*#* menu. Anyone wants to try?
[HTC Rezound] REV3NT3CH:
my phone works perfectly fine with a gsm sim card in it...ive updated to a jelly bean rom posted and updated the radios to most recent...check ot the loinks i just posted in the "is my phone dead" q&a post and update that latest ruu and hboot as well as to a jelly bean rom...in the setting in jellybean rom make sure you go to mobile networks and enable the network mode of gsm/wcdma and put in the proper access point names (apn's) and you should have no issues with your gsm at all....if you are on older ruu or firmware your gsm capabilities will lack greatly and be very very poor
[HTC Rezound] zwolf4444:
Are you getting HSPA on AT&T? My understanding was that you needed to modify stuff as described in the OP in this thread.
[HTC Rezound] REV3NT3CH:
i have used att, tmobile and straight talk perfectly fine with the updated radios and a jelly bean rom you need to be on the 2,23 raadios with the hboot 2.28 update...if you read the link in the q&a "is my phone dead" post it explains everything....those on old radios will have major issues such as this as well as not setting your apn's for your data correctly if you search att access point names you can find them and add them in the mobile network section in the settings of your phone....also if you have an extended battery again you will have issues with its copper painted antenna on the battery door...and i posted a link on how to get better reception as well thats an instructable....my phone currently is running gsm to its full capabilities perfectly fine...
[HTC Rezound] kkozma:
I can't seem to get into diag mode anymore. I had NO issues what so ever before using the following command. Al I have done recently was upgrade to the new 2.23 radios and 2.28 HBOOT.

echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on

Now when I try that I get

root@android:/ # echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on
/system/bin/sh: can't create /sys/devices/virtual/android_usb/android0/f_diag/on
: No such file or directory
1|root@android:/ #

Anyone?
[HTC Rezound] pkopalek:
That doesn't look right.

Did your ROM change?

Is USB debugging off, instead of on? or on instead of off?

I was hoping to see some more progress in this thread for HSPA. Wish I knew how NV edits really worked!
[HTC Rezound] Ecom3000:
Flashing to new rom

Will my NV edit stay they same if i flash to a jellybean rom?
[HTC Rezound] IcyAgitator:
I have the latest Global Radios & HBoot 2.28 and on a JB Rom. When you say working perfectly fine, are you getting 3G/4G, LTE speeds on those other networks? I am not able to get anything faster than Edge on Tmo and StraightTalk.

If so, what did you do specifically to achieve this? This would be greatly appreciated for the rest of us. :)

[HTC Rezound] bendog2784:
I just did this today. I got the H for a few minutes but it went back to Edge and hasn't returned since. I tried flashing the sensation file someone else posted and it didn't seem to make a difference. This is on Straight Talk with an ATT SIM.
[HTC Rezound] REV3NT3CH:
OK I've made somewhat the fix and will get 4g on ST but same issues as previous poster...won't stick but can repeat it...I'm gonna try and go deeper so it sticks although I fear it has to do within the deep insides
[HTC Rezound] bendog2784:
Did you flash the sensation nv that was posted in here? I noticed today that my Item 1877 was something different than what's in the OP. It must have changed when I flashed the sensation and I never "corrected" it. I am back to only doing the steps in the OP and going to try it all day and see what happens.
[HTC Rezound] acejavelin:
Wait... your getting 4G on Straight Talk?!?! Do you mean REAL 4G/LTE or just HSPA+? T-Mobile or AT&T SIM?

Your doing better than I ever got with this, I could never get basic 3G (HSPA) to even come up, only EDGE, and I tried every trick I could find and never got anywhere and finally gave up and went to a Nexus 4 and an AT&T GoPhone SIM and sold my beloved Rezound.
[HTC Rezound] REV3NT3CH:
Its a number of things including build.prop modding and code and a few tweaks
[HTC Rezound] bendog2784:
I am getting HSPA currently with my Reezy. The speedtest app clocks me at 3 Mb down 1 up which is good enough for now. Network Signal Info shows me on a 14.4 Mbps network.
[HTC Rezound] REV3NT3CH:
ok so i have news...4g requires AT&T Compatible Micro SIM Card from straight talk with a micro sim to normal sim adapter and can be bought of walmart website and have this as its model number TF64PSIMC4MB card and can also be bought of walmart website and only works via dfs tools writing this 87 03 E8 04 00 00 02 00 or 87 03 E8 06 00 00 02 00 in nv tab mentioned method in original post....the 06 number enables 850/1900+1700...oh and still a few other modifications like enabling lte for gsm in build.prop and such....it sure pays off...will write up a good guide and make a flashable zip for the other tweaks

Edit: Weird only seems to work on a sense global rom with umts capabilities
[HTC Rezound] XAlexander_AlexanderX:
I can't believe my eyes. I think I'm still dreaming. *pinches self* So you think this can work on T-Mobile US since it activates the 1700? *excited*:D
[HTC Rezound] REV3NT3CH:
as posted above only works with that particular att sim...also have a friend who works for a big name company and apprently straight talk and att recently struck a huge deal...and then news of this new sim emerged in recent times...so after almost completely failing every chance i got on the tmobile sim....i tried this att micro sim that they released with a few edits in nv that wasnt originally posted and miscellaneous other stuff and poof....i about soiled myself too bud when i actually saw it....i havent slept much in the last 30 some odd hours and havent slept yet tonight...err morning...so i thought my eyes played tricks on me....they werent

Edit: Just note this will only work on stock rom...i tried jb roms and data with all proper settings and it wouldnt even show or connect to data
[HTC Rezound] XAlexander_AlexanderX:
Lol I know I wouldn't go to sleep either. Have you tried a micro T-Mobile sim card? and will it work on Sun_Dream's ROM (sense) since it has the UMTS option (excluding tmobile sim)? That's some awesome work you got accomplished! :highfive:
[HTC Rezound] REV3NT3CH:
so far t-mobile will not get 4g on their st sim cards and this is on straight talks side...only achievable withh the att micro sim...ill have links up soon
[HTC Rezound] bendog2784:
Are you getting LTE with this new setup?
[HTC Rezound] REV3NT3CH:
im getting anywhere between 34 to 36 mb dl speed so id say yea
[HTC Rezound] bendog2784:
Great! I look forward to your write up.
[HTC Rezound] REV3NT3CH:
Thanks [MENTION=2672755]mschluss[/MENTION] for your recent donation. It is very much so appreciated. The guide will be posted within the next few days now that i have some time off to really do alot of the image work and such
[HTC Rezound] AtomicFizzle:
So is 3G possible for T-Mobile? Also is there a way to do the NV edits that doesn't require some weird Windows program? I don't use Windows at home anymore. At the moment just crunchbang.
[HTC Rezound] REV3NT3CH:
no it isnt possibly with tmobile or any t-mobile based cards and is only achievable by doing the edits with cdma workshop...not DFS as dfs doesnt let any of the edits stick....it requires a few certain changes in hex edits....and build.prop edits....

Edit: for 4g on ST it requires a certain kind of att card as well....still working on guide....its a very critical process to get it to work right so bear with me as i am so close to being done with it
[HTC Rezound] Starfox:
I need a stock RF file from a Rezound, right now mine is acting up when selecting certain radio types.

Also, I tried getting the RF calibration from a MyTouch 4G Slide (Doubleshot), but even though I enabled the diag mode on a stock rom, I'm not getting any response from DFS when connected. Any pointers on how to get this done would be appreciated.

-- Starfox
[HTC Rezound] REV3NT3CH:
Dfs won't let anything stick on the rez...use CDMA workshop
[HTC Rezound] REV3NT3CH:
new update...reading through nv files and such can be a real pain...and using ones that wont brick your device is even more hair pulling....however....once fully done with att guide...i plan on possibly working on t-mobile 4g nv edits....i've come a long way since the start but may have some tricks...just need testers in the future....im pretty much done on the ATT guide and will be posted within the next 48 hours....just have a few more lines to add and proofread every step carefully...havent made any flashables so this is a do it yourself at your own risk guide for now
[HTC Rezound] XAlexander_AlexanderX:
You got a T-Mobile tester right here lol
[HTC Rezound] REV3NT3CH:
My big guess is if its possible with at&t its possible to an extent with tmobile though i have heard horror stories about it....ive learnrd alot about nv items the last couple of weeks and i spotted a flaw in mine....once i leave my area of within a few miles ill lose 4g and only have hspa speeds at around 14mb's which could just be a refarming issue....theres a little more coding in the nv besides what was posted....item 1878 as well as quite another few need them...such as removing a 1 and replacing it with a zero....to enable that frequency where as its been disabled by default....i think i found a method where ill have you guys download a free program and just write the nv text file through it so there is less of a hassle of doing each one individually....i do however want to thank the OP and people who have worked with him to get to the point they did....without it i would never have been able to make it this far....

HUGE EDIT: i also found out how to enter band mode in phone...in nove launcher i select shortcuts>activities>settings and in the long list it will say band....gives me many options...but says unsuccesful everytime
[HTC Rezound] mschluss:
For those having problems getting connection errors for diag mode try this:

Reboot your phone attached to PC. Dial ##3424# as soon as possible and bf sum card is recognized.

Also best to use stock from or ruu.

Finally windows 7 is required to get the HTC drivers installed automatically.

Hope that helps.
[HTC Rezound] bendog2784:
Any update on the guide?
[HTC Rezound] REV3NT3CH:
still working on some hex code for t-mobile users...cant guarantee 4g will work on t-mobile based cards though....ive found there are quite a few bands that are completely locked in the rezound....more than likely done by big red or fcc themselves...aside from doing this guide ive also been helping on and building my own version of KitKat made for gsm users only as gsm requires a few seperate settings and quite a few other commits and cherry picks such than what verizon global offers
[HTC Rezound] greensmurfet:
Just got my Rezound a few days ago from my brother. I was using the Vivid on ATT. I"m still on ATT and now I'm s-off running the 4.03.605.2 RUU. Waiting on this guide to unleash 3G/4G capabilities. Edge sucks, lol. It may be completely useless at this point since you seem to have everything you need already but if I can help by getting any calibrations off of my Vivid, let me know. People were talking about the same chip being on the I717 but I only have access to the Note II and its on Verizon anyways.

Also, question: should I wait to update to the 4.05.605.14 RUU until you are done with the guide?

Thanks for all your help and to everyone else in the thread that contributed. I read through the whole thing. Pretty interesting stuff.
[HTC Rezound] REV3NT3CH:
if you follow the guide at the begginning you will get 3g.....and there is no such thing as 4.05.605.14 RUU.....only the OTA PH98IMG.zip file
[HTC Rezound] twfs:
Many are still not able to get 3g with this edit alone. The bionic on tmobile thread that the original post refers to talks about there being 3 different hardware versions and one of them the nv edit works one version you have a 50/50 chance of it working and the last one no luck at all. Beginning to wonder if there is different hardware version of the resound is why some can get it and others not. Also have not seen any posts of build prop edits anywhere. Best of luck
[HTC Rezound] REV3NT3CH:
google gsm build.prop edits or even look for a device with very similar specs that uses gsm...trust me there are a few msm8660 devices...and from original post...instead of using DFS as that program doesnt work and does not make the edit stick there is a free nv reader writer program based off cdma workshop....that program makes it stick....also instead of 87 03 E8 04 00 00 02 use 87 03 E8 06 00 00 02....im guaranteeing you the reason it is NOT working for some rezounds is because DFS doesnt stick error and i have noted this pages back in this thread...i have 2 rezounds that are two different boards....trust me ive done the research....and the edit works for both to get 3g/hspa....must also be on stock rom and ive suggested using kw6ke's global.....also make sure you have the proper APN's for your carrier.....att especially has an apn for each seperate band...ie 4g/3g/2g where as some others do not.....to get 4g requires more nv edits in other areas than posted in OP as the other bands are locked in hex way further down the line....with a wife and kids at home plus work reviewing each hex code is very time consuming....as i stated i did get it to temporarily fix but have issues with a few certain things....like loosing reception alltogether until i change a few things in the *#*#4636#*#* code and do a reboot
[HTC Rezound] twfs:
I have the exact minisim that you are suggesting to use in one of your earlier posts. I have tried 87 03 E8 06 00 00 02 00 and 87 03 E8 04 00 00 02 00 in nv line 1877. Have sent and verified with cdma NV-items reader_writer v1.0 and DFS cdma tool. On stock rom selected gsm/umts and selected umts only..... Also have downloaded Radioswitcher app from playstore to make sure WCDMA is selected turn off and on radio and still have no signal.Can change to global or gsm and get edge data only.I am not doubting that you have made this work but is there something here that I am missing? Thank you
[HTC Rezound] REV3NT3CH:
the nv reader writer is all you will need you have to send spc code in nv reader writer to push and pull nv's properly.....i may just make a quick youtube video on what you need to do....DFS does not work....on the stock global rom i provided in my s-off guide is what ive done it on...you do not need any app to switch to cdma....in dialer type *#*#4636#*#* what my major guess is is that you are putting your apns in correctly for the 3g...im using straight talk dont know which exact one you are using.....you also need to make sure you are on fsm and umts mode....not just one or the other...and set the apn's in the gsm / umts options.....what apns are you using currently...also with the micro sim....not mini sim did you get the micro sim adapter as i suggested
[HTC Rezound] greensmurfet:
Dropping calls and signal loss

Well, I did as REV3NT3CH said. I'm running on the latest radio (2.23) and software (4.05.605.14 710RD). I did as the first post stated except I left the setting on GSM and UMTS because I wasn't getting signal otherwise. I'm getting 3G and H in town but not at my house. Also, seems like my phone has been dropping calls and having random signal loss after I did this.

I wouldn't mind going through all the code if I had the right device to compare handy. Also, online I'm finding discrepancies on which devices actually use the MSM8660 depending on which site you go to. Need a little more time to check but so far seems like the Note I and the Pantech Burst (I'm on ATT) would work. The HTC Vivid has a different chipset.

Also, I used the APN from my last phone which was the HTC Vivid and there was only one APN. Seems to be working fine with just the one on my Rezound. I can send/receive calls and texts and sms although it does sporadically refuse to send texts.
[HTC Rezound] twfs:
First off I would like to thank you both for replying.By minisim I was meaning the medium size one because I am under the impression that the nanosim is the smallest. The apn setting that I am using is the same that works in my Inspire 4g and get HSDPA signal with so I don't think there is anything wrong with my apn with the same sim. I'm sure it is probably something that I am missing or maybe it just such a weak signal that I can't get it were i'm at. Will put in sim again then at work tomorrow were my current phone is usually maxxed out with signal see what happens.I am on same rom and radio as greensmurfete and have the sim adapter.Thanks again.

Boot loop

Hi, i'm using my rezound in Mexico and it's supposed to be the same steps (I think) but after restrarting my phone it constantly reboots, and cannot change from gsm/umts to cdma. Any idea what i did wrong?
[HTC Rezound] REV3NT3CH:
well for one DFS doesnt work for the rezound...for 2 the reboots depend on which ROM you are currently using
[HTC Rezound] kitcostantino:
Hey REV3NT3CH ! A few things...first, thank you for making my TWRP so awesome with the red masque theme., Next, thank you for all your work on this. Also, thank you in advance for the possibility of a KK GSM Rezound rom. (rocking Carbon 2/9 right now on VZW) I have put several Bionics on ATT Straight Talk using CellZealot's help and the Bionic Tri-fecta thread. I have a Rezound that I want to do the edits for Straight Talk with the ATT sim on. The Bionics I have used radio comm on never get anything but Edge or HSPA+. The reception range for HSPA+, as mentioned, is very short. I was wondering if UMTS/ATT 3G works with better *signal quality*. Where I work, my buddy/tester/st att subscriber, gets 4 bars of HSPA+. 2 miles up the road at his apartment, Edge only. (on his Bionic I hacked) I am trying to figure out if the 3g referenced as working is the HSPA that he gets or if this works for the full range of ATT's ST network with better reception than the Bionic. Obviously, the Rezound has better frequency ranges. I just was uncertain if UMTS worked or not. (doesn't on Bionic for sure) Sorry to be so caffeinated, man....I work in EMS and am 3 cups in. THANK YOU>
[HTC Rezound] REV3NT3CH:
hspa+ is 4g ...hspda is 3g...UMTS does work but as stated most actual radio frequencies are locked in hex code...i have all the files pulled on my pc and even have a qcm file to edit...im honestly still amateur at hex coding but have gotten close...in due time i will have a rom for rezound but the edits will have to be made in nv or qcm to get 4g to work...wont be just a flash and expect to fully work thing....with those frequencies that lets say att or tmo is calling for being locked all the current hex on here does is slightly bypass the frequencies the rez does have unlocked to use it...and is pretty short range because of it...id love bringing this thread back to life with help....either that or it will be awhile
[HTC Rezound] kitcostantino:
I get where you are coming from man. The bionic had to have the nv edits and there were/are only 3 ROMs pre-configured with the build.prop edits, (and they sucked). Maybe a tweaked hacked version of carbon 2/9 if snuzzo would be cool with his work being used. As far as hex, it may aswell be gGreek to me. I do want to expound upon my knowledge though. At this point, I couldn't compile if I had to. Soi am handicapped a good bit. But I do have a Rezound with a bad charging port I don't mind bricking. ;) let me know what I can do/when/how I can help man.
[HTC Rezound] REV3NT3CH:
yea sure....the best to start with being able to do the nv edits is latest global stock rooted rom....as we need that for a certain menu....also after nv edits are made you can actually use it on any rom you want so long as one does build.prop edits after boot to ensure its full potential...i actually noticed a few things in source code as well that will really help the gsm users when made

ATT Guide

I've been looking for your guide but can't find it. Can you point me in the right direction? Thanks

Edit: I'm on the Global_OTA_Blue_v2 rom. Should that be ok?
[HTC Rezound] REV3NT3CH:
cause i dont have one...everyone just pm me if you need help for now...
[HTC Rezound] scottww2622:
The main thing is how do I enter the new code in CDMA Workshop or NV Reader Writer? Do I read NV and replace the HEX code in the .txt file and write it back or do I need a hex editor to write the new code. I can't find the same settings/options when following the instructions in OP.

Also, my computer seems to connect to multiple com ports but both read NV but both files are different sizes.
[HTC Rezound] afishyate:
To anyone on a non Sense ROM having trouble flashing the latest 4.05 ROM for DM mode, I found that TWRP was unable to flash it directly while Amon was. You can temporarily boot it by using "fastboot boot amonrecovert.IMG". This completely avoids having to relock and use RUUs. If you're S-on you'll obviously have to flash the boot.IMG. I already have the latest radios though, even though I've only ever installed 4.03 before, so you may need to relock for that.

Looking forward to the full guide. Would love the draft right now. I may be able to help with the T-Mobile testings since my wife has a SIM, unless there is a 4g SIM.
[HTC Rezound] DarkRazorZ:
Is it possible to enable the 2100 band? I find myself returning to the Rezound because my HTC One hard bricked. Order the M8 HTC one but will have to wait a few weeks for it to get here. I get voice and texting but no data currently, not even when trying the trick mentioned in the OP. All help appreciated
[HTC Rezound] acejavelin:
I am assuming you mean T-Mobile's 1700 AWS bands (1700/2100Mhz)? Not possible, the Rezound doesn't have hardware support for that, on T-Mobile you will only get 2G/Edge network.
[HTC Rezound] DarkRazorZ:
Or possibly the 800/1800 bands, I'm not entirely sure what exact bands KT Olleh supports but I know my HTC One worked with HSPA on it
[HTC Rezound] acejavelin:
Ah... OK, that's a little different. KT Olleh is a Korean carrier, the cellular market is a little different there... There is no more 2G service according to several online sources, I am surprised you get any, but I did find this:

Olleh

2G Voice: 1.8Ghz CDMA2000 1x (currently not available, support ended in 2010)

2G Data: 1.8Ghz CDMA2000 1x Ev-DO rev.0 (currently not available, support ended in 2010)

3G Voice: 2.1Ghz WCDMA

3G Data: 2.1Ghz WCDMA HSDPA/HSUPA/HSPA+

4G Voice: 1.8Ghz LTE (Only in case of VoLTE voice call)

4G Data: 1.8Ghz LTE

I don't know if the 2.1Mhz WCDMA is supported in the Rez or not, if you change modes to WCDMA (Preferred) and put in your APN information it should either work or not.

There is much discussion on how this is a "world" phone but it really isn't... look here might be of some help: http://xdaforums.com/showthread.php?t=1421341
[HTC Rezound] DarkRazorZ:
Eh, it must be 2100 WCDMA then, I'l tinker with it some more but if the data still doesn't work then I suppose I'll just have to wait the week or two for my One M8 to get here, thank you for the help
[HTC Rezound] Anseri:
I know this thread I'd old, but is the information still valid? Or has something else been done that makes this obsolete?

Edit: Also, can this be done with a Linux machine? As that's my main Dev machine and the wife won't let me mess around with her windblows.
