So I happen to see a very popular thread here in the EVO sub-forum which reveals that many EVO 4g users don't even have Sprint evdo coverage. I was a little surprised because this Sprint EVDO roaming question has been asked for years while it seems no one has posted the workaround.
Using the Alltel PRL may not be a good idea because it will always try Alltel/Verizon towers first even when you are in an area with good Sprint coverage. If you ask Sprint, they will sure tell you this is in violation of their terms of service and it is possible to get your account in trouble. And if this exploit gets abused by the public, dang, you can be sure Sprint will close the loophole and everyone's game is over.
I'd suggest to take caution and only do the roaming when it is necessary. The straight forward workaround would be doing the ##775# stuff and load a Verizon PRL when it is in need and load back the Sprint PRL other times.
This method sounds a little awkward as you have to load a different PRL each time you switch roaming. The following is an improved method for the tech savvies.
You will need to install QPST found here.
1. On your phone dial ##3424#
2. Connect your phone to the Windows PC. Install the modem driver attached.
3. Open QPST Configuration, add the com port your phone attached to.
4. Open QPST Service Programming. It will try to find your phone. Click OK to open your phone.
5. Click "Read from Phone". It will ask for SPC/MSL code. Get the code either by calling Sprint or google search "Touch Pro MSL".
6. Go to CDMA tab. Copy everything from NAM1 to NAM2 except the AOC.
7. Download Verizon PRL from here or any newer one.
8. Go to Roam tab, click NAM2, click browse, find the PRL/RLA you just downloaded.
9. Click "Write to Phone".
10. Install the attached unhide_nam2.cab. Restart your phone.
Now on your phone, Settings, Personal, Phone, Services, You will find an option "Switch NAM". Swtich to NAM2 when you need to EVDO roam onto Verizon, and switch back to Sprint when you done. The phone does not need to restart during the switch. You can even write a mortscript to automate the switching process.
Now Sprint online shows data roaming usage and "additional charge". Will this long time free gift going to be charged? Nobody knows what's going to happen next. As being said before, when it get abused, it gets closed. In such a short time. Some people just don't get it.
Several of my friends work for Sprint. They all say that Sprint usually throws on additional charges when you data roam over 300MB minimum. Usually, it's at 500MB.
dam this is pretty good! gonna give this a shot!
Work on EVO ?
Anyone know if this might work on an EVO 4G ?
my touch pro 2 has no option in qpst for NAM2...only NAM1
any ideas?
ok...so anyhow I managed to get all the NAM2 information written to the phone however whenever an internet connection is attempted from the verizon side, I get "unable to connect to #777"...
yup...you guessed it, figured that one out too after a bit. use a 4xxxx PRL.
Does anyone know if theirs a similar unhidenam2 .apk for Android phones. I'm trying to get something like this for my evo

Hello, I cant find NAM 2
Can someone help me?
Hello good people of XDA! I suppose I should preface this by saying that I am indeed a noob at this; however, I have programmed a remote control before so I should be good to go .
In any case I would like to activate an EVO 3d on the Page Plus service, which uses the Verizon network. I have heard people on this forum and youtube claim that they have activated the Evo 3d on page plus, but I have not seen any instructions on how to do it. Let me also say that I don't really care about getting data to work, text + talk would be all that I really would need.
From perusing the forums I have read how people have activated this phone on other networks and how they have activated the Evo 4g on Page Plus, and I believe that I have pieced together how to go about getting this phone to work on Page Plus. However, I wanted to double check if this would work before I go out and buy it.
From what I gather I would have to:
1. Get Page Plus to add the phone's ESN to the network and have them provide me the assigned phone number (MDN) and MIN.
2. Use CDMA Workshop to set the SPC to all 0's.
3. Use QPST to enter the MIN and phone number onto the phone and an page plus PRL.
Will that work or am I missing something, o just plain dreaming? Thank you in advance.
i have a Droid DNA, s-off, bootloader unlocked, super cid and custom 4.4.2 with sense 6.0. i have 4G on my other phone (HTC One M7) and want to use my sim in the droid. i only get 3G. what can i do to connect to 4G?
It probably doesn't have the bands for your providers 4g
The only LTE band enabled by default on the Droid DNA is band 13.
You will have to enable the other bands to make it work.
1.) Install original factory ROM (You could use another ROM but I don't know how to get to Diagnostic mode in others such as CM11).
2.) Install a custom kernel. I has to be created from source, not stock.
3.) Download and install QPST and QXDM.
4.) Plug in phone, let it install the drivers
5.) Type: ##3424# and then hit send, let it install all drivers. This will take a while, ensure it completes before attempting to continue.
6.) Open a file browser and navigate to the "C:/Program Files/Qualcomm/QPST/bin" folder, and start the program "QPSTConfig.exe" (run as administrator by right clicking).
7.) I had two devices listed under the "ports" tab. Only one mentioned an ESN, it was the SURF9615.
Note: If it isn't showing up already under the "ports" tab, go to "Add New Port". Select the one that has 9k in it. You may have to untick "Show serial USB/QC Diagnostic ports only" to see it.
8.) (OPTIONAL, ***But highly recommended***) Now select the QPST Start Clients > Software download > Backup > Start. This saves a backup copy of your phone's stock NV memory to your computer in case you need it later. (I would also recommend that you write down the original values before you make any changes.)
9.) Again in the QPST Configuration program, go to the "Start clients" tab. Start "Service Programming" program. Select to load your device. Then click "read from device". This will send your SPC program code, which should be 000000. This will allow the next program to work.
10.) Next, run QXDM Professional (again, right click and run as administrator).
11.) Change the "view" tab to "NV Browser".
12.) Go to the communications tab in the menu of QXDM and tick the line that lists your device. Under "Target Port", make sure it lists the COM for the device that mentioned 9k earlier.
13.) Once it has loaded the NV items, go to the line 06828 and click "read".
14.) Click once in the box with the current value (should be 4096), and then edit it to be 0. Then, tell QXDM to "write" the value by clicking that box at the bottom right of the program.
15.) You may now click the box again and change this line to reflect whatever band(s) you want to enable.
Now, do the same for 06829.
Tip: You can calculate your own values for this or download the program called "Qualcomm NV Calculator" (It is free). If you use this program, you will use the LTE Bands Calculation tab. You will need to go to the menu in the top right corner and select "LTE Bands Calculation" and tell it that you want to "Use QXDM Notation" in order to get the right values. Enter the decimal result for the 6828 & 6829 values.
Reboot your phone. It should now have whatever bands you have selected enabled.
I know this looks tedious but literally takes about 30 seconds after doing it a few times.
Note: Other programs that you may find useful are "LTE Discovery" and "Network Diagnostics".
did it a 100 times.. with all the band combinations that i could get out of that program.. still not getting 4G signal.. so i think i won't be able to use 4G.. will stick to the 3G. by the way the bands for Romania are : 3,7,20. in NV the code is : 524356

Sorry to hear that it didn't work. Many qualcomm devices are capable of all bands, but it is possible the DNA is not. I did notice on my device that 4G seems to be disabled altogether when I did this on Verizon. So, maybe there is something I've missed.
maybe we are doing something wrong.. i see that more Qualcomm phones are able to see more lte bands (see oneplus one).. so maybe if we use a CM ROM?? i guess it could be ok, because in Diag (*#*#4636#*#*) after selecting LTE it goes back to WCDMA in a flash.. after unlocking all bands when i select LTE is says no service.. so who knows.
The 4G radio in Verizon phones is drastically different as the frequency is different. It isn't AWS like a majority of other 4G radios. Sadly it might never work without changing the hardware out which will cause major issues.

This may not be completely accurate. This method has been used on several devices it would appear: http://forum.xda-developers.com/showthread.php?t=2291589
Also, if you look down in this post, it appears that some phones require you to manually select that you want to activate the bands by dialing *#2263# (or some variation of this) and then selecting the bands that are desired: http://forum.xda-developers.com/showthread.php?t=1547114
It may* work on the DNA. In the end, this may be a hardware related issue, but is is likely just a software related one (I believe). I honestly believe this is essentially the same hardware as the Butterfly with different radios and software. It is fully capable of using the bands you are wanting. However, this is just my theory and remains to be proven.

Those aren't Verizon variants. Those are phones that were built with AWS in mind. The DNA is a CDMA phone with a few GSM bands built into it because Verizon told HTC they wanted a global phone and told them the bands they wanted and the ones they wanted excluded from the phone. There have been ex DNA and ex Rezound (another HTC global phone for Verizon) users who have tried for quite awhile in trying to get these "magical hidden" radios to work and it all came down to that they aren't there in these variants.
You can search and dig up old DNA and rezound threads from years ago and see the amount of work done.
Edit: Checked the old threads. The GSM bands for the DNA is as below. It doesn't support the 1700/2100 (ul/dl scheme) of AWS LTE as it is missing the 1700 in its radio altogether. The phone would need both 2100 and 1700 in UTMS to allow the correct 1700 up link and 2100 down link connections. This phone just lacks the hardware.
It wasn't made to be a GSM only phone. It was initially meant to be used on Verizon and work on international carriers when going on holiday.

I appreciate your input, but did you read the OP or my posts fully?
If you did, you should realize that I fully understand that the Butterfly isn't a Verizon variant, it is the other way around. I was suggesting that there is a possibility that the phone might be able to unlock additional bands because it is basically the same phone as other GSM variants only branded and modified for Verizon as you can see here: http://www.gsmarena.com/htc_butterfly-5118.php
This has been done in the past with other devices including Verizon devices such as the GS5, LGG3, etc as discussed here: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
While, I expect you already know this... It all boils down to the fact that R&D cost money. It's often cheaper for manufacterers to slap the same hardware in a device and modify the software to the liking of carriers such as by limiting the bands.
By the way, if you read the OP you would know that band 4 LTE is useless to the OP because he is trying to the phone in Europe, where there is no carrier using that band. You list the bands that the phone has been approved for, but as I mentioned above but other variants of this phone exist that utilize the bands the OP is looking for and there is a strong chance those variants share the same hardware. As mentioned above, this has been true for many other devices. I researched the topic and never found any conclusive proof that they can't be unlocked, so I felt like it might be worth his/her time to give it a shot since the method I listed is pretty easy and safe.
The Rezound is a much different device. It has no GSM radio. I would never have expected it to work on any GSM network...anywhere...ever. About the only things they have in common are that they are both produced for the Verizon carrier and use (different) snapdragon processors by HTC.
I do appreciate your input.

The Rezound does have a GSM radio. A number of users including myself have used it on other networks. Me personally, I tested it on T-Mobile and AT&T and got edge speeds. You are discussing a carrier who purposely burned out the FM radio in the Verizon M7 so it would not be functional. While you are right, HTC might have allowed the bands be made on the radio, it is highly unlikely. Others have tried. Some have even tried doing NV edits and didn't get it to work. This isn't the first time this subject has come up. The DNA can get some HSPA bands, some have tried to get some HSPA+ to work, some have tried getting 4G to work, one actually burned out his radio doing an incorrect NV edit. It has been tested before. HSPA in the US can only work on the refarmed areas. This has been talked about. HSPA will work in other countries that use the above bands specified.
If you are dealing with a carrier that will purposely tell the manufacturer to burn out an FM radio to force internet music streaming, why wouldn't they tell them to make a special radio for their variant? The reason the SGS5 and HTC One M8 work is because of the processor used, this phone is too old to work.
LTE in Europe
Hi, I live in Europe and in my coutry my carrier provides LTE, I've done the radio change with QPST and QXDM as described in post #3, I've enabled all the bands, but without luck.
I've the latest radio and hboot, tried some build.prop file tweas for LTE as described here, still no luck.
May be it's just a matter of some other setttings in buld.prop, but after many trials I think it has to be the radio, what blocks other LTE bands.
I had a bad idea to flash the radio made for HTC J Butterfly (HTL21), but I'm afraid of it (hardbrick), rather to find out, if it is the radio, what causes the problem and if it is, than figure out, how to edit the original radio (if it's possible).
Have anybody tried edit the radio or just able to read out something useful from it?
Somebody created a custom radio for Samsung devices as described here so I think it could be possible for DLX to.
I've been trying for over two weeks to root my LG Enact (Verizon branded), with no luck. This is not the most popular phone out there, but I like my QWERTY keyboard, I can't help it. It's an 8GB phone, the stock ROM is KitKat, it's a capable little device. So I'm going to keep at it until I find a solution. But I could use some help.
Unfortunately, I've tried just about every tethered AND untethered method out there, and nothing is working. The root-by-adb scripts run into a brick wall if they boot the phone into recovery, because the phone refuses to communicate that way, the computer says "Device not recognized" once recovery starts. (And all of those drivers are as up-to-date as I can make them.) The ones that use Download Mode (such as the LG One-Click Root method I tried, from this forum) get a little further, but they never complete the process. There are several apk methods that claim to be able to root without the adb connection, like framaroot, towelroot, kingoroot, etc., but none of these works either. I think I've tried them all. (And I'm going to have to do some hefty virus-scanning on my computer, after all the shady places I've wound up, from following bogus links while looking.)
The phone's stock ROM seems to have been set up with an extra layer of security which most devices don't have, which is one problem. We all know the "Allow installation of apps from unknown sources" option in the Security menu; mine also has a choice below it to "Disallow or warn before installation of apps that may cause harm", which of course I leave UN-checked. In Developer Options, grouped with USB Debugging, there is another "option" to "Verify apps over USB -- Check apps installed via ADB/ADT for harmful behavior", which is automatically checked when Debugging is enabled, but the "option" is grayed out and cannot be changed. So it's likely that NO tethered method will ever root this phone, because anything I attempt to install that way will be flagged as "harmful behavior".
Sorry this is growing so long, but you need to know what I've already explored, which explains my next question: there MAY be a way to run a root exploit directly from the phone, if I can find a way to manually place the file (such as the zipped ioroot exploit) in a folder which recovery can access, and this is where I'm asking for help. The stock recovery has two other selectable options, besides "Apply update from ADB" (which is where some file would be sideloaded, if the phone didn't stop communicating here) -- there is also "Apply update from cache", and "Apply update from external storage". I already have the appropriate file on the SD card, but when I try that option, the phone says it "Cannot mount SD card, no CSI structures installed", or something like that... which renders the SD unusable during recovery. If I look at the "Apply from cache" selection, it gives me four choices, which are "backup/", "fota/", "lost+found/", and "recovery/". The problem here is, none of those "cache" folders are in a location I can access... they must be in a system partition which I can't even see, without root.
So if anyone has ANY thoughts on this -- either how to force the phone to leave the SD mounted during recovery, or how to move a file to an invisible partition -- would be greatly appreciated.
Have you tried kingroot not kingoroot?
Tried them both, no dice
I used kingroot on Verizon LG VS890 (fx3q) running Android 4.4.2 to successfully achieve root. Saferoot and others did not work for me.
Rooted with NewKingrootV4.50_C120_B220_xda_release_2015_09_02_105243.apk installed with ES file explorer.
Thank you!!! That method finally worked for me.
Verizon
Glad I was able to help you.
Where you able to activate your phone on a new different provider? Even after rooting I wasn't able to get the Verizon VS890 to register on Canadian provider (Wind).
Thanks

Rooting would have nothing to do with activating this phone on another network. The LG VS890 (Enact) does not support GSM. The SIM slot is strictly for VZW LTE. This phone was not classified as a world phone, thus not needing to be unlocked like other VZW phones, and/or was produced before they were required to have their phones unlocked, but either way, it's not working on a GSM network.

Thanks for the reply, but Wind mobile is CDMA not GSM.

In the US, Verizon is mainly a CDMA network, although you can get Verizon phones that are capable of either type of network. If you have a CDMA network in Canada, the phone should work. I have mine set up with StraightTalk Wireless, which is run by WalMart (don't laugh, the service is CHEAP and very reliable). The procedure was NOT very straightforward, and their telephone support is ridiculous (very poor English, had to explain things several times, took three attempts to get it done, etc.), but perseverance paid off. Don't give up.
The thing I'm having trouble with now, is finding custom ROMs for the phone. It's running KitKat, so it's not ancient, and if I can't use anything but the stock ROM, so be it. But I'm dying to try flashing Lollipop or even Marshmallow. It has to be a very specific ROM for that phone, because of the keyboard... the wrong firmware won't function properly. And there are a lot of bogus sites out there which want you to "complete a survey" or "sign up for one of these offers", but they never give you the download, it's just an endless circle of phishing sites.

I'm not even from Canada and I know that is not correct. Wind Mobile is certainly GSM. It uses the same frequenices and bands as the American T-Mobile network.

Unfortunately, Zero, he's right. The "official" list of CDMA networks operating in Canada is small, and dwindling. Telus Mobility and Sasktel Mobility have CDMA through sometime in 2016, while Bell Mobiility plans to keep it through 2017. SogoTel is the only one which seems intent on staying CDMA, but they "roam" on Bell, so your coverage may be restricted after the 2017 cutoff. All depends on where the CDMA towers are located.
If you have WalMart up there, and you probably do (we call it "UberMart" down here), you may be able to get Straight-Talk like I have, which contracts to use both sets of towers as needed. Check their website, it should tell you if it's available in your area. Just be prepared to pull teeth to do it -- they will send you an "activation kit" for something like $4.99, which has a couple different sizes of SIM card (which the phone needs to operate correctly, just not for GSM access). Online activation may fail, and you'll have to spend a few hours talking with someone from India with very minimal training who will ask you the same questions over and over, assume it's a defective SIM card and send you a second one, all before finally getting the picture that it's NOT a GSM phone and has to be activated as CDMA. Worth the struggle, for the price. ($45/month, unlimited talk/data/text)... as long as your towers give you adequate CDMA coverage.
I appreciate everyone's input. I am an avid HTC user since the Hermes, slide out versions. Currently using a HTC M8 on Rogers, here in Canada. I stick with HTC because I've always been able to root and run custom roms, firmwares with the awesome support of this board.
I was trying to help out my little brother with his phone, despite my advice he just had to have a horizontal slide out keyboard so he ordered this phone. Big brothers job was to make it work.
We did our homework, and compared network specs, so technically this phone should work on Wind network (CDMA to CDMA same bands) but I didn't bother calling in for technical support. Perhaps if I had called in they may have pressed the correct buttons to activate the phone. The phone did accept the Wind SIM but never activated/registered.
He sent the phone back for refund so I can't play around with it anymore. Again, many thanks for everyone's help, input. Right or wrong, all appreciated. ZS
Hi all,
I tried searching xda forums but didn't find a place to ask the question. I have Verizon Palm phone 2018 model, but since Palm released this phone as standalone and sells on their website. I wanted to find out if anyone knows where or when can I find a firmware for the device, as I want to debrand it.
Any info about this? Really want to flash my Verizon branded Palm 2018 to an unlocked firmware
There seems to be very little discussion on the Palm Phone PVG100 here on XDA. We should start to see a lot more people on here looking to customize it, since it's a bargain (1/4 retail) as a refurb on eBay. I just picked one up and am curious if anyone has unlocked the bootloader, loaded TWRP, and rooted this thing.
I too am looking for a rom for this. I picked one of these up from verizon, and have been using it on tmobile with no problem, but want to get rid of the Verizon apps and branding.
Also, there seems to be MUCH room for improvement on battery life if the ROM is cleaned up.
It's a really nifty little device, just needs some TLC.
I was able to get to the bootloader via typical ADB commands, but can't locate any kind of ROM dump for these. I'm really surprised there isn't more discussion about these little buggers.
Palm PVG100
Hi everyone
I'm trying to modify my Palm too and it's curious to see that no information nor material is available online anywhere
I've started a new thread:
https://forum.xda-developers.com/android/help/palm-pvg100-pepito-development-t3971141
I was able to do something, but I still need help with what i say in my thread.
Basically I would like to take a full backup image of the device before starting tinkering with it, but I can't figure out how to make QPST software (Qualcomm Product Support Tool) show the content of the eMMC memory...
Anyone's help or collaboration for this project would be appreciated a lot!
Thanks!
We're you actually in the bootloader or recovery? I haven't been able to get into bootloader on mine. Any success unlocking bootloader?

I was able to get to the bootloader via typical ADB commands, but can't locate any kind of ROM dump for these. I'm really surprised there isn't more discussion about these little buggers.

Are you sure you want to use QPST. I have used it before to unlock LTE bands on a watch, but not for anything with the images / backups. I think the progression is unlocked bootloader, twrp compiled and loaded, then root. I also haven't seen the Pepito source code anywhere. Without that I'm not sure you will get far. I think the biggest hurdle right now is unlocking bootloader.
I've tried many root tools, nothing works.

Hi everyone
I'm trying to modify my Palm too and it's curious to see that no information nor material is available online anywhere
I've started a new thread:
https://forum.xda-developers.com/android/help/palm-pvg100-pepito-development-t3971141
I was able to do something, but I still need help with what i say in my thread.
Basically I would like to take a full backup image of the device before starting tinkering with it, but I can't figure out how to make QPST software (Qualcomm Product Support Tool) show the content of the eMMC memory...
Anyone's help or collaboration for this project would be appreciated a lot!
Thanks!

If you do boot into recovery, do not run Emergency Download Mode. You'll have to let the battery slowly die before you can do anything with your device.
Clarifications
Ok, thank you for your comments, guys, I really appreciate it.
Please feel free to correct me at any time, because I might make mistakes.
Just to make things clear:
I don't know exactly what you mean by "getting into the bootloader"; what I can tell you is that I was able to get into recovery and that in Settings->System->Developer Options (I'm sure you know that they are unlocked by tapping many times on the buid number), the Palm PVG100 (Pepito) has a switch that says "OEM Unlocking (Allow the boot loader to be unlocked)"; can you please comment on this?
It's not mandatory to use QPST, any solution is good for me (by the way, ONE OF THE PURPOSES FOR WHICH I WANT TO HACK INTO THE PHONE IS TO UNLOCK ITALIAN BANDS LIKE YOU!), but, as you say, no ROM exists on the web, so we have to find a way to extract the phone ROM and to decompile it (do you agree?).
TWRP doesn't exist for this phone, but, to compile it we need to extract protected files from the phone, right? (Please let me know if you know of a method to compile it without root access, nor ROM files)
In my opinion FIRST STEP IS TO HAVE A BACKUP IN CASE OF A BRICK, BEFORE STARTING TINKERING WITH RECOVERY, BOOTLOADER, PARTITIONS, ROM, FLASHERS AND ROOTING! (No?)
About EDL mode the problem is non-existent, I found out that, while in EDL mode, the Pepito can be restarted 100% of the time keeping the power button pressed for 2 minutes (120 seconds) (you can use a tight rubber band for this or any other trick), please test it
I've just had an idea, which requires strong reverse engineering skills. I have 2 Pepito phones; the first one has the most recent version of the software (1AGN), while the second one has the PREVIOUS ONE (1AGL) (see following link: https://www.verizonwireless.com/support/knowledge-base-221025/ )
This update must be doing something at an elevated privilege level. What if one sniffs what tnis update is doing when I force the update or reverse engineers the package obtained from the mother company as soon as it gets downloaded? Might it have information on how to sign software to make stock recovery ADB sideload fuction accept them? Or maybe provide us with information on how to enable write operation on protected partitions?
Ok. I can answer some of your questions here.
1. You haven't been in the bootloader, I'm not sure if there is one.
2. The OEM unlock bootloader in Dev options doesn't do anything but allow your phone to function (from that image) if you do unlock it. It's a security thing.
3. You unlock bootloader using fastboot commands, but Verizon is known for really locking down the bootloader.
4. I also have 2 phones on the different os versions as you have for a similar reason. I was hoping the root tools (kingroot, kingoroot, etc..) would be able to root one of them. Not the case. Both are solid from the standpoint of using standard root tools. I haven't seen many of them succeed after Android 7.1 anyhow.
5. Are you sure your bands are not already unlocked? Even if you get QPST to unlock the bands, it may not contain any data. So you will need to find another device with those bands unlocked to copy the data from (and that still may not work well). At this point I stopped my unlocking of bands project, as I'd didn't want to make a mistake and cook my brain. There has been very little success with band unlocking unless those bands already contained the data to function. Be careful with QPST.
6. I'm not a developer, so I can't really help with anything you are looking to do, but this is an amazing device and deserves the attention it needs to be rooted for at the very least better power management. Maybe underclocking.

Thank you very much for your post, it sheds some lights on the subject.
Well, you say "I'm not sure there is a bootloader", but bootloader is a mandatory piece of the boot chain followed by any device or computer able to boot operating systems, so every device has one; the device might not have a fastboot interface implemented, which is different...but yet annoying...
Standard root tools don't work, I agree, that's why we are looking for developer or board tinkerers help here
I'm 100% sure those bands are not unlocked, because my Italia Samsung Galaxy S5 sees LTE connection, while the Palm doesn't. Also see Palm specs here:
https://www.gsmarena.com/palm_palm-9290.php
It states:

Speed

You can see Italian LTE bands here:

It states:
LTE

Interface
B3 (1800 +)
LTE
B7 (2600)

I also contacted Palm support for the bands, requesting to unlock them in the firmware and they told me "Support for those bands is a hardware limitation, rather than something we can control in firmware. Unfortunately, those phones can't be made compatible with some 4G networks."...BUT DO YOU BELIEVE THEM?...
So, yes, I do have another device with those bands unlocked if needed.
With QPST there's no need to be careful until I find a way to make it communicate in read/write with the Palm :laugh::laugh: (just kidding)
Maybe if someone has opened a Palm phone and seen the internal board and knows how to perform electronic tampering, he can tell us what hardware components are involved in LTE communication (I think its embedded in the CPU...Qualcomm MSM8940 Snapdragon 435 (28 nm)...see the following link: http://phonedb.net/index.php?m=processor&id=658&c=qualcomm_snapdragon_435_msm8940&d=detailed_specs ...it states:

So I don't see why it doesn't support Italian bands, it makes no sense to me.
An electronic board tinkerer would help us a lot, possibly shorting some JTAG pins inside, maybe to disable read/write protection and, maybe, enable Emergency Download Mode with COM port in 9006 mode or some Diagnostic modes (not the 9008 mode, which was the only one I was able to achieve!)
)
In this forum where do you ask if you want to ask someone to help you connecting remotely to your phone to do live operations on it, using remote COM port software or remote control software (like TeamViewer) or if you need someone able to tinker with board circuitry?
I'm cooking my brain too and I would like to perform the operations you need too for battery life improvement and for my personal cullture, to possibly become of some help for this community, if someone teaches me these things..

Wow, thanks, interesting documentation!
Excuse me, looking at the FCC documentation, is there a way to find out if the phone hardware supports Italian LTE bands or not? Please explain exactly what information to look at for understanding this.
Thanks!
This signed at the bottom of the fcc page:
This device contains GSM/WCDMA/LTE functions that are not operational in U.S. Territories. This filing is only applicable for 700 MHz MBS, 850 MHz Cell, 1700 MHz AWS and 1900 MHz PCS operations

That is even if it has other bands (and it does have them), they weren't tested by FCC.

So Palm probably told me a lie and the hardware supports other bands
There is one additional thing for which I wanted to gain access to the ROM, to root and to custom ROMs and recoveries. Maybe you can help me with this.
I wrote to Palm company, asking:
Good morning
My Palm PVG100 receives Whatsapp messages only when I tap on the Whatsapp icon to open the application, but it's of utmost importance for my job to receive notifications when the phone is locked and to hear the corresponding sound, like it happens with SMS.
How can I achieve this?
Please tell me all steps in detail
Thank you very much in advance!
Francesco
They gave me a list of useless suggestions:
If you are a WhatsApp user and would like to sync your WhatsApp messages between your Palm and another device, you can use WhatsApp Web on one of your devices. WhatsApp allows an account to be signed into the mobile app on one device and another device on WhatsApp Web simultaneously. To setup WhatsApp Web, visit web.whatsapp.com to get started.

Hi Francisco,
I'm sorry for my unclear response. Are you using WhatsApp on another mobile device, in addition to your Palm?
Have you tried whitelisting the app in the Life Mode advanced menu? Try this out: https://palmsupport.zendesk.com/hc/en-us/articles/360021806871-I-am-having-issues-with-notifications
Then I sent them various screenshots showing the settings under which the problem still occurs; I attach a zip file with all the screenshots to this message, can you please have a look at it and help me with your experience, since Palm is not responding?
The behavior is like Whatsapp service gets killed from the background or notifications are held, because notifications come in if they come some seconds after I lock the screen, but if I wait, nothing comes in
When lifemode is on and screen is off, my assumption is everything is off. If you read the 'whitelisting' in lifemode only allows notifications to work in those apps when the screen is on.

the snapdragon chip will always have all the bands! The only limitation for enabling a disabled band I've seen is 'lack of antennas' no clue exactly what that means, I guess there can be different antenna lengths for different bands. Also as I've seen the lack of data for the bands to operate in qpst
Did you manage to access band data of the Palm in QPST?!
No, I haven't used QPST with the palm. you should try it.
