its just the modem is should be fine ... i don't see why it would cause any issues

you can always revert back if there are any issues

on the razr m the modem works for both ics and jb
[RAZR HD General] radiohead7778580:
i will take a screenshots when im in a 1900mhz area and some speed test results
[RAZR HD General] seh6183:
First off this is just awesome. I wish this would have happened two weeks ago because I may not have bought this xt925 from eBay.

2 questions. What about flashing the xt925 radio so us AT&T users may be able to have LTE? Also, does anyone know what areas AT&T 1900mhz covers? Like does it blanket all the areas that they offer H+? Or is the 1900 band only in certain areas?

Great work!
[RAZR HD General] radiohead7778580:
I am not sure I will grab xt925 from work on Monday and play around with it to see if this possible :o

Love my job
[RAZR HD General] seh6183:

Do you have to do anything special to get the data to work? I flashed this on my Razr HD and popped in a Tmobile prepaid sim, I can make phone call, but no sign of data connection. Do you have to change apn or something? Thanks a whole bunch!
[RAZR HD General] radiohead7778580:
Check your APN settings

Also change from global to gsm in network settings then reboot
[RAZR HD General] yalkowni:
So this allows Verizon hd's to be used on Att/Tmobil?!?
[RAZR HD General] radiohead7778580:
Yes it does
[RAZR HD General] yalkowni:
So what is the speeds it would get it might just sell my xt925 and get a droid razr maxx HD
[RAZR HD General] seh6183:
It's crazy man. Just nuts. I spent 500 bucks on this xt925 and it just arrived yesterday. I'll sell it in a heartbeat if I knew I could at least get h+ on a maxx. Just the way it goes.

I just need to know what kind of coverage and speeds ill get with only the 1900 band. Back to the mercy of unreliable testers lol
[RAZR HD General] igwtapc:
Works Like A Charm

If anyone is wondering then not to worry. Worked great on my Razr Maxx HD.

Will post pics once I got the phone setup.
[RAZR HD General] radiohead7778580:
on t-mobile when i was getting h+ it was around 10mbps that's only with 2 bars

my friend on att is getting around 12-14mbps

you can see the t-mobile 1900mhz band coverage here

[RAZR HD General] radiohead7778580:
Awesome glad to hear it :)
[RAZR HD General] seh6183:
Just looked up the AT&T 1900 coverage map and I covers the entire United States. That's excellent news. This means it comes down to the following for using a razr hd on AT&T:

Razr HD maxx with a bigger battery and higher storage but NO lte

Razr hd xt925 with all functioning features and unlock able bootloader, just lower storage and smaller battery.

Both good options.
[RAZR HD General] an21281:

Guess I am just out of range of 1900 only getting edge at the house.

Edit: Just took it into a T-Mobile 1900 area and still got Edge :(
[RAZR HD General] radiohead7778580:
Its coming soon.. By the end if the year

Mine switches over right away when I'm in a 1900mhz area
[RAZR HD General] donwhall70:
Guess I now have a decision to make.. I have an N4 that should be showing up here in the next week... Do I use that or do I deal with edge/hspa +/wifi while waiting on the whole area to be refarmed.. Either way I am done with Verizon... Suppose I could use Straight Talk for a while.
[RAZR HD General] donwhall70:
Anyone else getting H+? I was just near the USA T-Mobile Headquarters in Bellevue and still had Edge :|
[RAZR HD General] coolbird:
You could apply the latest JB leak on top of ICS with unlock radio flashed? I tried it but the OTA leak wouldn't install. I had to go back to stock ICS 4.0.4 then update to JB OTA leak, but after flash your unlock radio, I lost root on JB. Is the "erase userdata" step necessary on your flash file?
[RAZR HD General] radiohead7778580:
you cant update with the radio flash the stock radio in the OP then flash the modified radio :)
[RAZR HD General] radiohead7778580:
Check OP there are no wipe versions

test them out please
[RAZR HD General] coolbird:
Thanks! I was able to get Tmobile pay-as-you-go sim card working, but no data. Maybe pasy-as-you-go plan doesn't allow data connection. But I have trouble with ATT sim card, I popped in a sim from Blackberry, it worked for a little bit, then stopped working. At one point, I even could get HSPA+ connection, but no luck on that any more, not even the voice working. Well ,,,
[RAZR HD General] joshw0000:

[RAZR HD General] seh6183:
Now that this has been out for a few days, can anyone with AT&T confirm how well the H+ is working? Also what state they live in? Thanks in advance. Thinking about switching to the MAXX and selling my xt925.
[RAZR HD General] coolbird:
The screen on my phone doesn't rotate at all. I flashed so many times I don't remember when it started to happen. I am not sure it is a Jelly Bean thing, or this flash and no wipe radio thing. I know that the auto rotate worked fine in ICS.
[RAZR HD General] drtrask:
Does modem flash still allow VZW connectivity?

If I were to flash the modem update so I can also use my T-mobile SIM in the phone when desired, does the modem update also retain VZW LTE connectivity?
[RAZR HD General] radiohead7778580:
no ... stock modem for Verizon and unlock modem for gsm
[RAZR HD General] pimp2xg:
modem unlock

Can anyone confirm if this will work on Straight Talk AT&T with 3G data? I tried it on t-mobile prepaid sim but got only edge :eek:(
[RAZR HD General] Germanese:
What modem/radio is this based off ?

Trying to see if we can use this same radio on our Razr M ...

We been using Aussie so far and the 3G and 4G is either non existent or shaky.

[RAZR HD General] aslomagic:
Well, I guess the right question is, if I flash this on my RAZR m, and it doesn't work, will I be able to restore it with fastboot or will I have an expensive paperweight? If I'm 100% sure that I cannot hard brick my phone, I'll just try it...
[RAZR HD General] radiohead7778580:

[RAZR HD General] donwhall70:
I really don't know.. my nexus 4 is getting +42 but my maxx hd is still getting edge.
[RAZR HD General] yalkowni:
That's because you have tmobile and the maxx hd dosent support tmo 4g bands while the nexus 4 does
[RAZR HD General] donwhall70:
Maybe I am wrong here but doesn't hspa+ run on 1900mHz in refarmed areas? Does hspa+ 42 run on the 1700mHz band as well?

Our area has been refarmed but I am still getting edge on the HD.
[RAZR HD General] trezegol:
need some help i have a razr hd verizon i flash the unlock radio and i pop in my att sim card but works for about a few mins them i cant do anything else does anyone have or know the settings so that it would work with att or what else do i need to do thanks
[RAZR HD General] Cpudan80:
Can you be more specific? What happens exactly?

- Does it revert to emergency calls only?

- Does data stop working but calls/txt keep on truckin?

- Are you set to "Global" network mode or "GSM"?

- Are APN settings still showing up under the network settings screen?
[RAZR HD General] trezegol:
i flashed the unlock radio when i use my att sim i get signal i get H+ for the first few mins i can call and text but after about 10mins i will still get signal but when i make a call doesnt riing or nothing just hangs up... but with my tmobile sim works great.. is there a setting or something that i have to make to get my att service working ? thanks for your help

data stops working to also calls and text like if theres no service

[RAZR HD General] india23:
What if set you it to "GSM" instead of "GLOBAL"

I am really interested in knowing if this works or not. I would love to get a maxx HD to use on AT&T. Please let us know if that does anything.

Thanks.

Can anyone confirm if there is a issue on at&t with this unlocked radio?

I want to put my RAZR HD on straight talk using at&t towers
[RAZR HD General] donwhall70:
Guess I will ask one last time.. Can anyone other than the OP confirm that they have working 3G on T-Mobile? I talked to t-mobile today and I am dead smack in the middle of a refarmed area in Seattle, WA and I am still getting edge only. I am going to fastboot my device and see if that does anything but I doubt it will.... Looks like I will just keep the N4 and sell my Maxx HD... I had really high hopes for keeping it on T-Mobile :(
[RAZR HD General] lreeb1:
I got my razr HD today. I flashed the radio and inserted my T-Mobile sim. I am only getting Edge for the most part but twice I have seen it switch to 3g and H+, but only for a second, then it switches back to Edge. I am in Houston and also have the refarmed 1900. The APN settings are the same as the ones I used for my N4. I've tried various network types, too, from dialing *#*#4636#*#*.

Sorry, this won't help you, but mainly just confirm what you/re seeing. I still have a little bit of hope since I have seen it switch to 3g.
[RAZR HD General] donwhall70:
I guess you are lucky as you have seen it actually go to 3G lol
[RAZR HD General] lreeb1:
I saw the radio for the xt925 posted on here somewhere. Do you think it's a possibility or worth flashing? I don't mind trying, if flashing back won't be an issue.

Update: I flashed the Rogers radio but I'm still only getting Edge with T-Mobile prepaid. Trying to get my hands on an AT&T sim card to see how it works.

Update 2: I was only getting Edge with the Rogers radio and T-Mobile, but I just left my office to go to an AT&T store to try their microsim and all the sudden I am getting H+ and 12mbs download on T-Mobile. But as soon as I got back to the office, Edge only. To clarify, with the nexus 4 I was getting H+ at my office, too. While at the AT&T store trying out their simcard I was able to get H+ but I don't know how reliable it is since I only used it while sitting at their store.

I'm feeling confident that 3g and H+ should work with AT&T, I'm just waiting for a straight talk simcard to thoroughly check.
[RAZR HD General] pimp2xg:
Tested tonight with a straight talk sim using AT&T's network. I get Edge,then it switches to H+ then to H. At one point it switched to 3G. But it keeps switching back and fourth. The only stable connection it will sit at is edge. Is there something wrong with this radio not accepting 3g?
[RAZR HD General] pimp2xg:
Does anyone have a fix for this? Is this a fast dormancy issue or something else?
[RAZR HD General] vuphongkkk:
So far i got two issues on the razr maxx hd with this radio.

1. Landscape mode doesn't work

It seems to work a little better but I am still only getting a consistent Edge connection. If I set it to Global or GSM/UMTS it will show H,H+ for about 3 or 4 mins then it will switch back to Edge again. I'm on Jelly Bean 4.1.1 and using my Straight Talk AT&T sim. Any ideas of what could be wrong? I live in a 1900 MHZ 3g area
[RAZR HD General] radiohead7778580:
i will take a look...

i dont live in a 1900mhz area i only get h+ at work so i will look into it tomorrow

Just went outside of my house and look what's working... Nice

Tmobile 1900mhz band
[RAZR HD General] mengder:
thanks again for the hard work. the old no wipe worked great on my tmobile sim, except data stays edge most of the time,

i wonder if there'll be a no wipe option on this 12/15 update
[RAZR HD General] radiohead7778580:
yeah i can do that.. but i did the wipe so it would fix the rotate issue
[RAZR HD General] radiohead7778580:
OP UPDATE

no wipe added
[RAZR HD General] mengder:
you are awesome! sorry have to ask, what's is the rotate problem?

and sometimes i get this message when i open settings, "just wait fro a moment while we prepare for this application ", below it the circle goes for a while, then a alert msg with red triangle popup, "sorry, we're having trouble connecting. make sure you have a good signal and try again. if you still can't connect, call us at 800-922-0204. error code 1001"

can i disable this msg?
[RAZR HD General] radiohead7778580:
for some people auto rotate stop working...

i will see what i can do about that message that you are getting
[RAZR HD General] pimp2xg:
I tested it tonight again and i'm only getting edge on Global or GSM/UMTS. The only time I will see H and H+ pop up is when I set it on LTE/CDMA/Evdo/GSM/WCDMA. It connects to H, H+ for about 5 minutes at most then I will lose signal and it will go back to edge. I know I have AT&T 3G on Straight Talk in my area because I had Straight Talk on my Iphone 4s a while back
[RAZR HD General] vuphongkkk:
Thank you for your hard work.

I flashed the new radio . It fixed the rotate problem.

I found some spot that have strong 1900mhz and it showed H+, but most of other place that I had H+ on my xt910, this one show edge.

[RAZR HD General] vuphongkkk:
No. I never rooted it
[RAZR HD General] mengder:
i have edge most of time to, and don't know if it's just coincidence, when i try to use the edge in some area, the H/H+ shows for a short moment, then the phone lost signal for a few seconds, then back to normal.
[RAZR HD General] projektorboy:
Holy crap. I did not know this hack existed for the Developer Razr HD. I think I may need to buy one now so I can monkey around on T-Mobile.

Verizon Razr Maxx HD

Hi Radiohead,

Please can you give step by stepp of how to go about this please.

From what I understand:

1. I should flash in rsd lite to wipe data

2. Then Unlock with this download link

Modem Unlock:

Not allowed to post links cos i'm pretty new on this forum

3. Flash again and Insert sim card?

Sorry, i'm pretty new in this but I have an IT knowledge as a web programmer. I just need each clear step to do this. (I know i'm doing it on my own risk)

I will be glad if you can help me with the steps clearly

Thanks
[RAZR HD General] seh6183:
Its pretty unreliable man. You probably won't even get 3G. And if you do it will drop randomly or texts wont go through and what not.
[RAZR HD General] jckunle:
Yea I don't mind, just wanna try it first and if its too much of a problem I will flash it back.

Can you states the steps please

Thanks
[RAZR HD General] seh6183:
Download the 12/15 WIPE .zip

Extract the zip

Open RSD lite 6.0

Point the tool to the .zip folder that you just extracted

Select the .xml file

Click start and let it flash the radio

When the phone boots go to settings>mobile networks>and change the type to GSM/UMTS

At the very bottom it will let you search for networks, click that and select MARITIME 3G

Thats it

The service is very unreliable and will come and go. Also you may want to enable roaming, it may be necessary as well.
[RAZR HD General] jckunle:
Thanks so much I will do that.
[RAZR HD General] jckunle:
Actually everything works fine for me. I have E, H and H+ both inside and outside. Works really fine. At first I had problem with it but I changed some settings on my mobile APN and started working fine immediately I saved it
[RAZR HD General] seh6183:
I tried the standard Cingular APN as well as the PTA APN. Which did you use? You're saying your connection is flawless and doesn't drop and all?
[RAZR HD General] jckunle:
Yes My connection was fine. No dropping at all, Maybe its because I'm using Simple Mobile but then Simple Mobile runs on T Mobile tower so I don't see why it won't work fine on T Mobile and AT&T.

They only disappear when I activate wi-fi setting for my wireless usage. What are you APN settings

I wish there is a way I could show you the the screen inside and outside.
[RAZR HD General] seh6183:
Well I'm using AT&T. I'm pretty sure T-Mobile fairs better with this modem than AT&T does.
[RAZR HD General] jckunle:
Is it any of this specification:

Android 4.0 & 4.1 (Ice Cream Sandwich & Jelly Bean)

Android 1.6 – 2.3.4 (Gingerbread
[RAZR HD General] radiohead7778580:
I Will make some more modem files and you guys can check what works best for you

do you guys prefer wipe or no wipe or both?

Also this helps a lot with stability and to keep H+

change this in the build.prop

ro.mot.ds.fastdormancy.disable=true

telephony.lteOnCdmaDevice=0

ro.telephony.default_network=3
