[HTC Rezound] acejavelin:
Because this only works on phones that have specific bands/frequencies disabled in the chipset, the Rezound does not have the capability at all, simple as that .
[HTC Rezound] Snuzzo:
Do you have a Rezound? If not kind of makes you're links null as I would suggest you to test everything.

Also uncertain why you mentioned me in the post .....

[HTC Rezound] Yura80:
I've loaded WCDMA 800 and 1900 RF calibration items from Bionic. There is some improvement: phone shows decent signal level and can make calls where it previously had no service. But there is still some weird behavior, like intermittent HSPA connection loss and dropped calls.

We need a RF NV backup from a GSM/UMTS phone based on MSM8660 or MSM8260.

This is the list from Wikipedia:

- Sensation

- Evo 3D GSM

- Vivid 4G

- One S

- myTouch 4G Slide

It's easy to do with DFS:

- do steps 1-4 from the top post.

- go to NV page, click Read RF, let it finish, then click Save and share the resulting NVM file.

This file is safe to share as it contains only RF calibration data and no serial or phone numbers.
[HTC Rezound] gampt:
I've tried pulling data from vivid but ##3424 command doesn't work on it. Also no diag ports available after connecting to PC. I might be able to get a hold of sensation later today or tomorrow.
[HTC Rezound] Yura80:
Did you try to run DMCmdBroadcastReceiver from Hidden Menus app?
[HTC Rezound] Yura80:
Please also try this method or this one

There is no DMCmdBroadcastReceiver entry in hidden menus. When I dial ##3424# I get an error saying connection problem or invalid MMI code.

This shouldn't break Vzw CDMA/CMDA2000 (EV-DO)/LTE reception, right? I use an AT&T prepaid SIM when travelling, but normally use Vzw, so I'd like it enable it when I'm travelling but keep my Vzw too.

Hi Yora80. What does that line mean ?

Thanks
[HTC Rezound] siulmagic:
Yura80 im guessing you did this on a stock rom if so, i believe the only way to acces the DM mode is in a Stock based rom. i tried the command, and the hidden app menu app, and nether work, im guessing its only our stock rom that can access that menu, i will flash our stock ics rom, and let you know how it goes.

Current rom im using, is my own personal pyramid cm9 port.

edit. as i suspected the Dm mode is only available in stock roms, now im trying to use the cdma workshop, but the onyl version i can find is 3.8, and does not have the buttons or tabs that you describe on your thread, so im looking for cdma workshop 3.5, if i find it il let you know.

It's working fine on Newt Sense 4.1.

***Yuro80 : In Seattle, I can now get T-Mobile 4G/3G on ATT unlocked phone. But for some reasons I still cant get the Rezound to access 3G after modifying as shown. Any suggestion beyond this point ? Thanks

then theres a smaller box with nv-items , has 2 buttons read and write, theres is none for start or end search rages.

no im just providing it to yura, im not sure witch line contains the calibration, if any atall, me and my bro ported, the the rezound rom to his amaze, so we could get into dmcbroadcast mode. and dump the nv
[HTC Rezound] Yura80:
siulmagic,

Thanks for your help!

For some reason, there are only 4 nv items in your NVF file. Normally there should be many more. File size should be about 200-300kb.

Are you sure you clicked "SPC" button before "Read RF"?
[HTC Rezound] bedwa:
I'll take a look at the Bionic calibration this evening and what NV numbers it is. My wife is using the bionic and we may be able to use the calibration from that. We may also want to experiment with cross using this workaround with the existing GSM patch to use both chips.

Update: For some reason my connection to my wife's phone is not working for me this evening. Extremely frustrating. Will continue to probe. Be back later tonight if not tomorrow morning.
[HTC Rezound] siulmagic:
hmm i cant remeber right now, but i can grab another dump, il try and grab one before my bro sells the phone.
[HTC Rezound] bedwa:
Btw, what are the NV items for calibration? We'll need those numbers to pull the right info. ;)

(And my apologies on not noticing the info with the bionic pull.. I feel silly now.)
[HTC Rezound] siulmagic:
i tried pulling the nv file again, but it came out the same size, around 1kb~, do i need the simcard on the device, while saving the dump?
[HTC Rezound] Atruss12:
Just curious to if this only works on stock roms?
[HTC Rezound] siulmagic:
it should work on all roms, but the diag mode, can only be accessed in our stock rom, or any cdma sense4 rom,
[HTC Rezound] Atruss12:
So once done on a stock rom its done for good, even after another wipe and flash? Also, I use T-Mobile, will I be able to send and receive texts and calls?
[HTC Rezound] bedwa:
As long as the ril files are compatible and you do not change the radio files, yes.
[HTC Rezound] Atruss12:
I'm considering trading for a rezound so I wanna make sure everything works with T-Mobile lol. Can ya blame me? Appreciate the friendly help
[HTC Rezound] bedwa:
not one bit. This has got me tinkering with my Rezound again, while my wife and I use a Droid 3 and Bionic. We're all about not using phones branded for our own carrier.... lolz.
[HTC Rezound] Atruss12:
So... this will for sure work with T-Mobile haha gotta make sure before I go without a phone ;)

I'm gonna be trying this out today sir. If it works, I won't need that trade anymore. Lol
[HTC Rezound] Atruss12:
Lol alright

Did you try using RF calibration from sensation? Please post the results.
[HTC Rezound] ehcan:
Isn't the Amaze 4G is a APQ8060 instead of a MSM8660 and use a different radio chipset?
[HTC Rezound] slavasz:
I tried it on my Rezound with Fido (Markham, GTA, Canada). First I thought it didn't work as there was no change. It was still on EDGE, while my wife's HTC One was on 4G. But, when we went today to different places in town mine started to show "3G" and "H" in most of them

Thanks!
[HTC Rezound] apocalypt077:
Any progress on this?
[HTC Rezound] anubis2k3:
So I finally got this working using a straight talk at&t sim in south California. I now get 4G and 3G connections. I used to only get Edge.

Here's screenshots for ya's...

I did this using the steps in the OP and writing the qualcom nv to the rf using dfs. Pm me if you have a question and I'll try to help out.

Thanx so much for this thread. I thought I was going to have to get rid of my rezound for another GSM phone, which I really didn't want to do. Thanx so much! :D:D:D
[HTC Rezound] anubis2k3:
UPDATE:

Ok so I got it working as stated above, but the signal is very choppy. It goes in and out all the time with either no signal at all or back to edge. Weird to say the least. May be the new radio edits from the qualcom nv file. Anyone tried tweaking it with better results? I know nothing about hex editing or changing these values, I was only following directions and trying different suggestions and got lucky.

[HTC Rezound] NilayS:
Guys any idea how to get it work on Indian GSM operators ?

I am currently using myTouch 4G Slide on GSM 900 & 1800 Bands & UMTS HSDPA on 2100mhz bands in India perfectly.

I tried following the steps written in OP, but cudn't complete first step also, I dont get any pop up for installing HTCdiag drivers when connected with Charge only mode, nor does DFS show anything to start with.

If someone can help me extract from myTouch 4G slide i can post a fully calibrated RF from it so it can help us all.

P.S. I am a noob at all this but eager to learn.

EDIT: I am using a rooted, unlocked MT4GS with Rubix ICS v5.3 custom rom which doesnt have option of HTC Sync while connecting to PC.
[HTC Rezound] gampt:
It would be interesting to compare RF dumps from different phones. Mytouch is MSM8260. It may use the same radio or it may not. Too bad OP seems to have abandoned this thread. Hope I'm wrong.

I had to run the code on sensation manually to enable diag mode. You can run it in terminal emulator. Make sure path is the same on mytouch. If it's not, correct it, otherwise ain't gonna work.

[HTC Rezound] pda2renew:
Sorry I'm a newbie, is it possible to share your nand img(just default bootup from 1st flash and radio can access 3G)? Or if radio img is enough to get the 3G signal, would you please share the radio img and let me how to flash?

Thanks!!!
[HTC Rezound] anubis2k3:
I never thought of doing that. The next time I get access to a computer I will do it.
[HTC Rezound] bedwa:
This is true. Anyone who successfully gets it to work can dump their modified radio img and it should be as simple as a fastboot flash or zip repackage for boot flashing (on s-off devices only)
[HTC Rezound] anubis2k3:
I don't know how to make it flashable. And how would I get an img of my radio? With dfs? Off to Google!
[HTC Rezound] pda2renew:
boot to recovery and nand backup to SD card(default) if you are using AmonRa recovery tool.
[HTC Rezound] anubis2k3:
I'm using twrp recovery...but even if I had amonra how would a nand backup get me the radio.img? Doesn't it only backup data, system, and boot?
[HTC Rezound] pda2renew:
You are right. I tried nand backup with original radio and flash to different radio and nand restore, but radio stays at newly flashed version. :(

Is there any way to dump out the radio img or whole rom?
[HTC Rezound] anubis2k3:
Once I can gain access to the computer that I did all this on, I will be upping my phones nv file for everyone to try and write to their phones radio using dfs.
[HTC Rezound] bedwa:
If it's a single partition, we could "dd if=/proper/partition of=/sdcard/radio.img" it that way.

Edit: try /dev/block/mmcblk0p17 for the if=portion. Post or pm the modem. I would prefer to be the first to try. Please also let me know your exact modem name from your settings. Thanks!

Edit3: forgot to mention. Download android terminal emulator, type su, then the dd if= of= command above with the proper partition provided.
[HTC Rezound] gampt:
Don't you want mmcblk0p19 which is radio_config partition?
[HTC Rezound] bedwa:
Then let's go with that one. You have a valid point.

Edit: scratch that. I'm sure if you pull partition 19 you'll have an 8 meg file of all 0s.both my backup on the rezound and my pull from the amaze 4g were all 0s.
[HTC Rezound] anubis2k3:
Sent you a pm.
[HTC Rezound] anubis2k3:
Hey bedwa, did you have success with that IMG I sent you?
[HTC Rezound] bedwa:
Sorry. I forgot my Rezound over the weekend and just now got to try it out. It pulled signal after the replacement, but no 3G. I have another idea I'm going to try in the next few days and will get back with you on this.....
[HTC Rezound] rockingondrums:
Any word on this?

Giving my Rezound to my roommate, who wants to get off his iPhone and off AT&T. He's pretty set on using Straight Talk. We're in Norcal.

Believe me, I've done a lot of searching. Most of the information I find is old or inconclusive. Honestly, I'm sure he won't care which MVNO he's on, as long as he can get 3G. I want his first Android phone experience to be a good one. He has the TF101 so he's been using Android for awhile. Just want to make sure his phone doesn't let him down. Voice/sms/mms/3G data are essential to the user experience :D
[HTC Rezound] ddas8888:
Will this method work for lg spectrum vs 920? Both of them sharing same chipset? Can anyone confirm?
[HTC Rezound] sshaar:
Anyone know if this will work with a Straight Talk AT&T sim? I'm wanting to move to straight talk and keep this phone, but it would be nice to get the higher speeds.
[HTC Rezound] el Filou:
Hi guys, would a dump from a european EVO 3D (MSM8260) be useful, or wouldn't it provide any more info than the Sensation dump from gampt?

I'm also wondering: could this same method be used to try and change the LTE band on the MDM9k chip?

My operator uses 1800 MHz for LTE (Band 3), I suspect it wouldn't work very well if the radio is calibrated for 700 MHz but I wouldn't mind trying it anyway. ;)
[HTC Rezound] aaronandshag:
I wouldn't mind that either! I have AT&T and a rezound and would love to try and test it out as well. I'd also be happy to host the file if needed. Thanks!
[HTC Rezound] raymond36136:
I got the band changed successfully but still stuck on edge. Any suggestions?
[HTC Rezound] KileakX:
The tutorial worked perfectly, thanks :thumbup:

At the first attemp with the rom Rezound Maister 2.0 Sense 4.1 did not work the code to show the Diag Mode with Hidden Menus.apk then restore a nandroid backup with Sense 3.6 and everything worked perfect.

Very weak signal but i got H and 3G intermittently :D
[HTC Rezound] KileakX:
After modify the baseband for UMTS that currently has my cel (2.22.10.0801r - 2.22.10.0803r) presents some interesting details:

1.- If i restore a nandroid backup from another ROM (Sense 3.6 or 4.1) UMTS/HSPA data not working, only EDGE.

2.-. With factory reset also lost UMTS/HSPA data only EDGE.

Note that the baseband is still listed as modified in DFS CDMA Tool for UMTS/HSPA (87 03 E8 04 00 00 02 00).

What do you think happens, some tied file?

google translate, sorry :p
[HTC Rezound] bedwa:
I think it's a ROM/Baseband combined mod that's enabled by the DMPortRead.apk. Without it, I don't think it will work as I was enabling the edit another way to no success.
[HTC Rezound] I_SAY:
Do you think this will work on the LG VS920?, both use the same chipset so is it possible?
[HTC Rezound] bedwa:
I would highly doubt it.
[HTC Rezound] anubis2k3:
I've been running with hspa going good no matter what rom I use. I've flashed roms even used different recoveries. This doesn't sound rom based, at least from my own experiences.

Edit: spell correction made me say "I've flashed bands..." fixed now. Meant to say roms.
[HTC Rezound] bedwa:
Very interesting. What does your baseband say? I'm curious which one you have.
[HTC Rezound] anubis2k3:
Although this could be true, the rest was achieved by me just editing my radio in dfs using the files provided in the thread. If I can pull those from my phone then it would be easy for everyone I think. Anyone in north San Diego county reading this thread that has a computer I can use hit me up! :D
[HTC Rezound] gampt:
Do you mind revealing which NV items did you edit?
[HTC Rezound] bedwa:
Please refer to the OP. It's the same process anubis2k3 used.
[HTC Rezound] gampt:
Did you just edit item 1877 as per OP or did you use sensation.nvf file provided in the thread and edited more items?
[HTC Rezound] bedwa:
Nv 1877 is the correct route.
[HTC Rezound] gampt:
And why is it exactly that you're answering for anubis2k3? What is he incapacitated or something?
[HTC Rezound] bedwa:
I'm quite sure he's not, but all the info is here on what has worked for others and I've been in this thread since the early posts. Plus, if you look below my avatar, I've earned a little bit of clout to be able to point people in the right direction. I'm not always right as I am human, but I do know a little bit more of this situation than you do.
[HTC Rezound] gampt:
Frankly I don't give a damn what your avatar says. And I don't care if you know more or less than I do. You're not pointing anyone in the right direction by saying to refer to the OP and guessing what anubis2k3 meant. You're very funny guy.
[HTC Rezound] GrayBoltWolf:
I sense some flaming coming on......
[HTC Rezound] bedwa:
Not from me. Not worth the time or the headache.

A little history on me. I've built multiple kernels, been trying to tinker with basebands of this and the Samsung Note N7000, am using a Droid Bionic on AT&T and my wife has a Droid 3. Just trying to point someone in the right direction must not be enough anymore. I'll continue to be here, but I wish gampt best of luck as between a 40+ hr per week job and a family with myself, my wife, and two children, I don't have time to argue with those who do not help themselves. If clarification of instructions are needed, that's what we are all here for, not petty bickering.

My 2¢
[HTC Rezound] anubis2k3:
Just to set things straight, editing nv item 1877 with the values provided did nothing for me. It wasn't tell I started incorporating the nv files provided on page 4 and 5 that I was successful at getting 3g and hspa enabled and working...kinda, lol.
[HTC Rezound] bedwa:
That makes even more sense now. You overwrote the nv table, as when I was looking at available nv values in the QPST utility and it wasn't there. By you rewriting the table, it's available again and modifiable. Nice.
[HTC Rezound] El Schisne:
What is meant by "kinda"? What problems are you having?
[HTC Rezound] anubis2k3:
By "kinda", what i mean is, its very unstable switching from 3g/4g. In fact, i rarely see a stable 3G connection. Although, on the other hand, HSPA seems to be stable enough in areas where signal is good. I really dont know enough about hex editing and such to modify what i did, thats the area i need help in. :p
[HTC Rezound] KileakX:
I have it working with the instructions on the first post, only modify the baseband once in stock hboot 2.27 then downgrade hboot and baseband:

I agree mate :)
[HTC Rezound] anubis2k3:
So were you able to update hboot to the latest after the modification of your nv table?
[HTC Rezound] KileakX:
My Rezound is S-Off, had the stock hboot 2.27 and radio 2.22.10.0801r / 2.22.10.0803r (from latest RUU 4.03.605.2) where modify the baseband but UMTS not work.

Then downgrade, as I described above.

I think I can upgrade to the latest HBOOT and radios. UMTS will work this time? I doubt it :p

Note: With radio 1.22.10.0310r / 1.22.10.0308r i got many many random reboots :eek:
[HTC Rezound] anubis2k3:
well if your willing to try it then that would be cool. Otherwise it doesn't really matter I guess, unless roms that come out later on down the road require the latest hboot, as that has been the case in the past. Thanx for sharing your findings. Gets us closer to narrowing down why everyone is having issues achieving this when I and few others (yourself included) are the only successors with this hack. :cool:

their Hey guys. poking around and noticed that one of the note 1 variants has the msm8660 and runs on art 4g. Is there anything we can get and use from one of their radios. I know they are readily available and is we could compare them maybe something could make it easier to get the 1900 band live.
[HTC Rezound] Israelleite:
It's working in Brazil !

I'm able to use the phone WCDMA ONLY here in Brasil using CLARO, this is the only way I could get 3G or HSPA+.

If I choose global mode, the phone only get EDGE. :-/

I set us the phone using the NETMONITOR from PARIZENE .

[HTC Rezound] anubis2k3:
You either didn't read through the whole post right or I'm missing something. We have been successful (well some have been :rolleyes: ) at enabling the 1900mhz band for 3g/HSPA by using other GSM based phones NV tables. Now we are trying to not only narrow down exactly how its done so everyone can do it, as well as, trying to make the connection more stable.
[HTC Rezound] johny101010:
I understand but there are too many issues (weak signal, data drops, etc). I think some of the reasons include the fact that we are using calibration for a MSM8260, the I-717 is 8660, and that we do not have Nv-data and RF-data.

If someone has a i717 please try to get those for us. I can not guarantee anything but I believe it will make things much better. I can try to walk someone through if they have the note1.
