[ONE General] Furry.garf:
Installing OPO drivers went wrong!!

Hi, I own an SGH-I337M in Cuba, and I'm trying to unlock the 3G band for 900 MHZ which is the only band available in my country. My phone is able to connect to 2G 900MHZ, but not to 3G 900MHZ. The cuban government has recently approved and installed the 3G internet service and it's the latest news all over the country (I know, I know... we are centuries behind the technology :( :(:( ). Obviously I want to connect to internet wherever I am, as long as there is 3G, but my phone doesn't connect to it.

I followed this post (and many others) in order to do that, but every single time I try to "update" the drivers with the OPO file given here, I get the same error message from my laptop (ACER core i5 Windows 10 64bits) and it's basically that the driver is not signed and the hash is missing which means the file might be manipulated or damaged. So much for my hopes of unlocking bands for my phone!!! :rolleyes::rolleyes::rolleyes:

ANY HELP !!!!!!????????
[ONE General] Furry.garf:
Well, I already found out how to install unsigned drivers in my laptop, but I still cannot make the phone appear in the QPST Config window. I've done everything the tutorials say but I still don't get a positive response from the phone when I connect it to my computer. I read somewhere that stock roms are difficult, if not impossible, to unlock bands, and I think mine is a stock rom. It's as follows:

AP: I337MVLUGOH1

CP: I337MVLUGOH1

CSC: I337MOYAGOH1

RF Cal: 2013.04.27

HW Rev: REV0.3

I hope this info helps find out what's the problem.

IT GETS FRUSTRATING SOMETIMES TO SEE EVERYBODY CONNECTING TO INTERNET WHEN YOU CAN ONLY PLAY TETRIS. :crying::crying::crying:
[ONE General] x2bc4:
Hi Furry. I've been there already. I managed to unlock that band but with very poor signal reception. My only hope now is to find the ecuatorian version i337E to extract the qcn with the correct band calibration, because they used 900MHz too. If you find it, please let me know.

I also suspect that the original software versions of those phones had that band but were lost with the first operator's modem update. But getting a hand on any of those is even a more remote possibility.

In the meantime, try to get a hand on an pcb board from your same model because on the schematics I dont see a link to the antenna switch with that frequency. Maybe there is, and is not represented. If there isn't, we can still try to run a wire.

Good luck.

Will this method work on note4 n910v, ANDROAD 9, RR 7.0.1. trying to get baseband 28(700) LTE in Nigeria
[ONE General] whitedavidp:
I have graduated from fooling with my old Note3 (N900T) where this procedure seemed to work - at least in that the Network Signal Guru app would show the additional LTE bands I configured as present. Now I am trying to do the same with the real phone I need to get working - an Asus Zenfone Pro Max M1 (also known as an X00TD or ZB602KL).

While I was able to get the old Note 3 working without actually having to root the phone, I was not able to do so with the Zenfone. After rooting, I was able the use the adb shell command "su; setprop sys.usb.config diag,adb" and actually see my Windows 10 computer show a diagnostics 9091 com12 port and a modem 9091 on com11. I am not sure how it happened, but when I do the adb shell command "su; getprop sys.usb.config" I am shown diag,serial_cdev,rmnet,adb.

I tired running QPSTConfig.exe and things looked kind of OK but the phone showed an EIN of 0 until I slipped in some old nano SIM I had lying around. With that, I am able to run QPSTConfig.exe and things look pretty much the way they did for the Note 3 - although I did not manually add the port - it seems to have been auto-added.

In QPSTConfig.exe, I can perform Start Clients->Software Download->Backup and it seems to complete just fine - no errors and a file is written to disk. I can perform Start Clients->Service Programming then choose the Asus phone on com12 and it shows as online and looks pretty much how it did with the Note 3.

When I start QXDM.exe it shows as disconnected (while with the Note 3 it seemed connected immediately). When I went to the NV Browser all the items were grey. So I used Options->Communications and in the dialog I see that diagnostic com12 is checked and shows as active. But the Target Port field says disconnect. If I change that to the com12 it seems that the connection becomes valid - doesn't say disconnected and in the NV Browser the items are no longer grey.

But when I try to read item 06828 I get "NV Status Error Received: Item Inactive". Same for item 06829. With only a few, seemingly random exceptions, any item I try to read yields either get this error or "NV Status Error Received: Command Unrecognized".

This is using version 3.12.714 of QXDM.exe and QPST.exe 2.7, build 474. This phone is said to have Qualcomm SDM636 Snapdragon 636 processor. Is this not compatible or something?

Thanks for any suggestions.
[ONE General] gigix_xx:
Hello, i saved values with qxdm or rf_nv_manager, i read the nv again after saving, and the settings are saved, but when i reboot the phone, the nv gets back to it's default settings.. I don't get any error in qxdm when writing.. i have zenfone max msm8916 rooted by magisk.

There could be a problem with bootloader unlocker by asus, which game me a network error when unlocking.

if i use this C:\adb>fastboot oem device-info

(bootloader) Device tampered: false

(bootloader) Device unlocked: true

(bootloader) Device authorized: false

(bootloader) Device critical unlocked: false -maybe this doesn't allow me to write nv
[ONE General] Albirew:
This was why we had to patch rmt_storage on 1+1: in order to prevent nv recovery on reboot.

Can anyone explain how or why this patch is supposed to work? I'm having no luck with a Snapdragon S5 from T-mobile. Thanks
[ONE General] Albirew:
the "patch" was actually an old version of the file from before cyanogen team add the "reset nv values at boot" functionnality.

see the commit witch add this "functionnality" if you have sources for your model and plan to edit and build your own version...
[ONE General] x2bc4:
Sorry. No source code. But maybe there is another way. Since not all nv values are reset, I guess I need to find the origin of the default values and edit them. Thanks

Actually, i wrote "Tested only on kitkat and below" but it should read as "Working only on kitkat and below" as 1+ has locked NV write ability and rmt_storage patch was a file from old version from before they patch NV... File witch, just in case, changed drastically in later android versions

Hi guys! Anybody know..is this method works for Russian networks? I mean..Maybe I (or anybody from Russia) shouldn't do this "unlocked method"?

From Russia with love :)
[ONE General] jtchinoy:
What bands does Russia use?
[ONE General] maxim.m:
For WCDMA: Band 1 (Freq 2100)

For LTE: Band 7 (Freq 2600) and hardly ever Band 20 (Freq 800)

I'm asking because I think(or maybe I hope) this method will resolve issue with sometimes loss of network connection. Because I tried to install all of modems in the nearby thread and no one didn't help me :( :rolleyes:

Also I used "LTE/WCDMA" and "WCDMA preferred" modes. May be you know which of modes should be used for the better network connection?
[ONE General] jtchinoy:
Band 20 I dont know if this unlocks it. I do know my WCDMA and LTE up time is higher now compared to before modifying the values. You can give this a shot. It doesnt take much time. Just note your origina settings in case it doesnt yield you favorable results.

This is great work, has anyone looked at an OPPO Find 7, coz I'd like to know how the bands look.

The Find 7 is almost identical to the OnePlus One, both using the 8974-AC, but no Band 20 lte on the OPO

Keep up the good work.
[ONE General] fards:
Loss of connection seems to be more about power than modem band.
[ONE General] Lctwisk:
It would be very nice if someone manages to unlock LTE band 20 :)

I am willing to test if someone figures it out. (Although I am not sure how to test it since my provider also uses band 3 and 7 for LTE which are already supported).

In my area I've only bands 20, so if anyone find, I can test it. I've also an HTC one which support band 20 and in this place it had LTE. Opo doesn't.
[ONE General] jtchinoy:
According to phone arena, the Find 7a uses an 8974-AB, also I saw the S5 uses an MSM8974-AC, while the OPO uses an 8974-AC. I don't know what the differences are, but I've been trying to find which ones use the exact same processor. On the qualcomm website, the S5 and OPO supposedly use the same processor.

[ONE General] BlackSoulxxx:
Anyone pls check it....

Use QXDM to write it into NV (make sure every items is stick after write, someone forget to double check and spamming my PM box :p )

If my works was right, then OPO will use the band below:

GSM: DCS-1800/P-GSM/E-GSM/GSM-850/Railways-900/PCS-1900

WCDMA: Band I to XI

LTE:Band 1, 2, 3, 4, 5, 7, 8, 13, 17, 19, 20, 21 (no 23 at this time)

P/S: Some band will cant be use because OPO hardware lack of support it...

And QXDM is works normally here with Win 8.1 Update 1 +August update. So I don't understand why people cant make it works....
[ONE General] fards:
mine have stopped sticking after reboot, using the latest cm11 nightly, will investigate.
[ONE General] jtchinoy:
Do you know of any apps that let me scan for bands? i cant find a good app that tells me what band I'm using.
[ONE General] ck064:
Just for clarity, the Find 7 uses the MSM8974-AC and has 3Gb of ram, the Find 7a has the MSM8974-AB and 2Gb of ram.

This makes the Find 7 the twin of the OPO, they are even made on the same line I think, but with slightly different battery, screen, etc. This is why I believe that the lte band settings from the Find 7 hold the key here.
[ONE General] jtchinoy:
Do all of the 801 cpu have msm in their names?

Also, confirmed the Find 7 also has FDD-LTE band 20

If Find 7 have band 20, can you ask one of their owner to get nv 6828 so we can use confirmed value and not other value from other phone........

You have to get inside "hidden" menu to look at the band. I dont know if OPO had one........

I had all sorts of trouble trying to install all of this on Win8.1 (update 2)

Previously, I have used adb to upgrade ColorOS to CM11s on this system.

But trying to install the HTC Modem, Windows tells me that the .cat file has been modified, and it blocks the installation. Also, when I enter *#*#8778#*#* to go into Diagnostic Mode, nothing happens (that I can see). Only the code disappears from the dialer screen. Is this due to CM11s?

What am I missing here?

In device manager, I get the 2x A0001 devices, but I can't install the HTC Modem. And the adb shell keeps telling me that no device is connected, without MTP or PTP switched on.

I would really like to see LTE Band 28 become active on this phone. It is about to come live in Australia over the next couple of months, and will have better signal strength inside buildings. It would be nice to be able to access.

For Windows 8 you need to go to the advanced startup options and disable driver signature enforcement (F7). Then you will be able to install the driver.
