Old Samsung SGH-T989 as a vehicle tracking device and Mobile hotspot - T-Mobile Samsung Galaxy S II SGH-T989

I have an old US T-Mobile Samsung II, SGH-T989 phone, in good condition, running Jelly Bean.
I originally owned and used it in the USA and had installed a custom bootloader on it (CWM)
and had run Cryogen.
However when I moved back to the UK, my bank apps wouldn't run on Cryogen, and I also had to
change Telco provider. This meant that I had to revert the phone back to all it's original software,
so that T-mobile would unlock my phone from only using their SIM cards.
I managed to convert the phone back to the original bootloader and the Android Jelly Bean OS.
The phone was unlocked by T-mobile and all was well.
However at the time I didn't notice that the Mobile hotspot application on the phone was no longer working.
I have dug the phone out again with the intention of repurposing it, and would like to use the phone
as a vehicle tracking device, using (Google Find My Device) and as a mobile hotspot.
I have purchased a SIM card from a new Telco and it works fine in my other mobile phone as a mobile hotspot.
Everything would be fine, if the Mobile hotspot aspect worked in the SGH-T989 phone.
But it doesn't! The phone won't let me start the Mobile hotspot feature with my alternative SIM Card.
So, I figured I would possibly install, a new bootloader and OS, that might work and give me a hotspot on
this older phone.
Unfortunately so far, with no luck. I can't even seem to get the phone to 'Root'?
I have managed to install TWRP v2.5.0.0 but again 'No root'
Obviously the phone is fairly old, so finding solutions to this dilemma is even further frustrating.
What would be the ideal scenario, would be to 'root' the phone and put an operating system on it
that would allow remote access to the phone.
So that I could stash it in my vehicle with a USB charger cable attached and use it as a vehicle tracking device and
a hotspot router with something like 'Openwrt' LUCI running on it.
I'm not that good with computers, so I tend to use whatever prepackaged Mods are available.
If anyone could help me with just getting 'Root' on this model of phone that would be a great start.

USB Media mode Issues

Hey there XDA, ive been having an issue with my GSII T989 that i hope you can help me with.
I originally got the phone off ebay used as a replacement for my T499 that had a broken loudspeaker (couldnt hear calls or use alarm)
It came with the stock TMO version of 4.1.2. Im on the monthly 4G plan with TMO and my old phone didnt have any way to stop tethering so i was able to use it freely. I still do not feel it necessary that i should have to give TMO an extra $15 per month to use this feature, so naturally i avoided it as much as possible. in 4.1.2 the "tethering provision" app was disable-able, so i Initially planned to keep that on the phone, however the phone kept getting the update to the newest software pushed to it and i couldnt get the notification to go away. rather than upgrade to another rom that would inhibit tethering, i decided to put a custom rom on it.
After looking over a few, i decided to go with AOKP. at this point the phone was fully functional. I was able to copy all the related files to the phone over USB. I initially loaded the CWRM 4.0.4.3 and that went smoothly
of course when i attempted to load AOKP i hit a roadblock as i had not updated the Radio. i got the radio and copied the file over to the phone while it was in recovery mode, and then loaded the rom up. everything seemed to be great, until a few days later.
I tried plugging my phone into my PC to copy a photograph off of it to post online, and it wouldn't work. Initially i figured it might have been a problem with the cable i was using. Since it was used, the phone came with an off-brand cable. I tried my OE cable for my T499, still nothing.
eventually i went and enabled "USB debugging mode" in developer options, and then it worked! I thought that seemed really weird, but at least i could still get into it.
that was a few weeks ago. Now i have been thinking about trying another rom, and now i cannot get the USB media mode to work on my phone at all, on any of my PCs, whether in normal, USB Debug, or in recovery mode. I even tried converting to the touch version of CWRM to see if something was wrong with that, and it still wont connect. The PC detects the phone but it refuses to show the storage. when i Enable USB debugging mode, it connects and shows the media device, but promptly disconnects again a few seconds later for no apparent reason. It even did this with Kies running. Everything else on the phone works as it should and it has no trouble charging from a wall jack or from the usb cable.
If you guys could help that would be great
T-Mobile SGH-T989
AOKP 4.3, CWRM 4.0.4.3
32GB SDHC
I hope you've meant 6.0.4.3 CWM instead of 4.0.4.3. That's old-old-old-old-old, and 99% likely to not work with today's ROMs and etc. What I would do is try to setup ADB on your computer and use that to push/pull files from your phone for in cases like this where the phone or computer doesn't like MTP. I highly recommend using this guide to setup ADB if you're going that route.

[Q] Tether GPS for Un-Activated Phone

I'm looking for a way to use my "retired" HTC Incredible (ADR6410LVW - there seems to be more than one model # described as "Incredible") as a GPS puck. It was my wife's phone for 2 years and the screen is cracked, the battery is in bad shape, the camera lens is smudged, and it's been mistreated by each of my children. So it's in pretty rough shape, but I got it for a good price, and it still seems to work.
Because my tablet (rooted Kindle Fire 1st edition - stock ROM) doesn't have an internal GPS, I need to tether it to the phone to get mock GPS coordinates for several mapping applications. For this purpose, the phone works with TetherGPS if both devices are on the same (external) WiFi.
The problem is that with the provided Mobile Hotspot app, the software won't allow a connection unless there is a data source (i.e. Verizon network). Since the phone is de-activated, no source exists, so the mobile hotspot won't turn on. I will be using this in vehicles far from WiFi and I have no plans to re-activate a phone just to get a GPS. Maybe there is a way to trick the app into thinking there is a data source, I'm not sure.
My Kindle Fire doesn't seem to work with WiFi Direct on the phone, but I may not have the phone app set up right. I don't want to flash a new ROM to the Kindle because I still use it with Amazon content.
I've also tried Android WiFi Tether, but I run into permission errors on the phone, and it doesn't seem to be working.
I'd prefer not to root the phone if I don't have to, but if that's the only way, I'll do it. I have not applied any RadioComm edits, and don't know why I would need to unless that's how I get the stock app working or overcome the permission errors with Android WiFi Tether.
Can anyone give me some assistance?
EDIT: I have now learned that the different Incredible model numbers mean. Mine is 6410, which means it's 4G LTE and not the same as the original Incredible, and it means that I've posted in the wrong forum. I see that this forum is is for 6300, which was discontinued more than 3 years ago. My apologies, I'll try again in the correct forum.

Unlocked G2 w/ Max WiFi Users 1 + Questions

TLDR: Unlocked LG G2 was on Sprint, now on VIVA in Kuwait, Max WiFi users when running hotspot is 1 - I want to increase it to more.
Long version:
Hello! I am a military service member deployed to Kuwait. I have a Sprint LG G2 which is rooted and running the latest UltraPop ROM. Before I left the US, my phone was activated on the Sprint network and when I would use my WiFi hotspot, I had the ability to connect up to 10 users or something. When I got to Kuwait, I had to have my phone SIM unlocked for International use to make it work with the SIM cards provided by the carrier here (it's called VIVA). My phone was not on the Sprint network when I needed to unlock so when I did the UICC unlock it did an OTA over WiFi and then I was able to use my phone on their carrier. This is all well and good.
The problem is, I want to connect my laptop, my tablet and a few other items to my hot spot - thus the appeal of the hot spot, right? LOL. Anyway, several advanced options like the radio channel, frequency, etc. have now disappeared and in addition, the most important one - the amount of users able to connect to the hotspot, went from allowing 10 to 1. I am not sure why, except maybe something to do with the OTA update when I did the UICC unlock.
I did some reading and found this article: http://forum.xda-developers.com/showthread.php?t=2718682
Quickly I tried it and restarted my phone. No change. Then I noticed there was another hack for phones that had been activated on the Sprint network, which as I explained above, believe applies to me. This article has a more complicated procedure: http://forum.xda-developers.com/showthread.php?t=2675280
I am afraid to try this method and screw things up. I suppose I could boot in TWRP and do a NANDROID back up before I try it but I am wondering if anyone thinks it will hose the only working Internet I have right now in Kuwait.
Any help is appreciated. Also, if anyone knows how to get the WiFi hotspot to allow devices to connect while running a VPN at the same time please enlighten me!
Thanks!!!
Sincerely, Lost & Confused...
OK, so I am going to resurrect my own thread here. I spent some time on and off dealing with the 1 client max for the hot spot in my Sprint LG G2. Lots of frustration. Anyway, digging deeper based on a tip another friend of mine gave, I discovered something that I thought would have helped, but no cigar.
Anyway, a variable called max_num_sta in the file /data/misc/wifi/wpa_supplicant/hostapd.conf allows the access point to have only one client. The hostapd application on Android performs almost identical to an average Linux distro, so I figured by modifying this variable I would be able to allow more than 1 client to connect to my hotspot. However, even when changing the file manually, as soon as the hot spot is enabled thru the stock interface, only 1 client is able to connect and looking at the file again shows the value of the variable has been reset.
Next step on the list, was to run the hostapd manually from an Android terminal (something like hostapd -e/data/misc/wifi/entropy.bin -BK /data/misc/wifi/hostapd.conf). The command works at the hot spot functions, but again somehow resets to 1 freaking client again!
I would really like to be able to use my G2 to connect more than one device at a time to my hot spot while I am stuck in Kuwait. It is my only source of Internet. Anyway. Is there a way to disable the stock Wi-Fi Hot Spot interface using Titanium Back-up? Remove the APK? Modify the system? Something? I'd really like to figure this out. Any info or suggestion appreciated...

[sm-t705] build.prop question (spoofing)

Ok so my network (Three uk) disabled my unlimited wifi teathering some time ago which rendered the tablet i used at work useless.
So i went out and found myself a new big screen phone, the sm-t705, a little unwieldy as a phone but hay it works.
Only here comes the snag, when i put the sim card into the device the internet would not work, an error page tells me to put the sim card into a phone to get net, three tech support told me that my phone is a tablet and cant make phone calls .....i was using it to call them lol
Anyway, to the point, i recently read that a rooted device (i am rooted) can pretend to be another device by changing the build.prop there are tons of guilds on how to change it, though from the view point of making google play see it as a different device to install unsupported applications, seems straight forward (if a little risky) but here are my questions,
1) what sections do i need to change so the phone reports as a normal phone?
2) what phone should i spoof as? (im thinking i should spoof as a phone as close to my specs in terms of processor etc as possible to avoid installing a version of an app that may have different cpu requirements or may burn out my phones gpu)
3) anyone done this? any tips if you have?
Thanks in advance,all advice greatfully recieved.
Regarding your old tablet, have you tried Foxfi?
Foxfi doesn't need a tethering plan or root and can create a hotspot using either Bluetooth or wifi.
It works great for me.
Barnacle wifi also used to be good on older devices, but seems to have issues with newer ones.
I used it to create a hotspot on a device that didn't even support it.
All you need is Foxfi on the phone and pdanet on the tablet for the 2 to connect via Bluetooth. Foxfi provides the instructions and links to pdanet to get it up and running in minutes.
For your new tablet if the sim is detecting it is a tablet and three are blocking it from mobile data then I don't think a spoof using the build.prop will fool it as it uses the imei as far as I know.
You may be better off with an xposed module to spoof the device, even then I think your success will be limited.
It's a bit crap of three to do this. I use O2 and have no issues using my phone sim in any tablet.
Does the tablet not even make a mobile data connection?
Have you checked the apn settings are correct?

I used pdanet for a while, but would prefer to just use one device, the old tablet was sold to pay for the t705 (will part pay, damn this thing was pricy)
Does the imei reveal the device model?

It's used to identify the device, so they will know it's a tablet.
There is an xposed module called device faker, but like I say I think success will be limited as I think the sim will identify the imei from the hardware.
It's seems three don't want you using your tablet for data, do they have an explanation for this?
Maybe all you need is an updated sim card.
I have a three sim card that I can use for data, but if I want I can also make calls with it if I put credit on it.

This explains the issue better then I can,
http://www.pcadvisor.co.uk/opinion/...y-monthly-account-from-use-with-ipad-3368856/
As for why, the lady at the three shop told me the data to a tablet is different to the data to a phone as it's not the same operating system......I did my best to not laugh and asked to speak to a higher up, they told me that as it is a tablet and not a phone I would be breaching my contract if I used my simcard in it.....
The actual reason, someone who uses a tablet is more likly to use data and therefore they can get more money out of them via tablet plans with limited data... To sum up, greed.
My temporary solution is to use a bt simcard which gives me access to the world's most unstable bt WiFi network (which disconnects every 30 mins or so) I was hoping the build.prop would be the magic solution doh
I am not familiar with samsung builds, but i had this problem on my motorola phones, (tether locked and forbidden)
Ok, in motorola we have 2 prop files:
build.prop
And
cda.prop
In the cda.prop , i found a line
ro.tether.denied=true
try find this line on your device
If the line does not exists, try force to exist

And your carrier will nevermore be able to remotely set your device again forcing by a init.d script or putting this command in /system/bin/debuggerd:

Tethering isn't really the issue, it's that three block my simply from data access when I put it in my sm-t705 so I was hoping to make 3 think my sm-t705 was infact a Xperia z3 for example

Yes and no
Any page you try to access goes straight to a page three has to say that your sim card won't work in this device and to put it back in a phone, so while technically you have data you can't use it, no apps can use it either

So you actually do get a mobile data connection it's just any data sent is blocked.
Have you tried using a vpn, this can circumvent most carrier restrictions.
DotVPN is free and very good, available on play.
There is also TouchVPN, but DotVPN is better as its truly anonymous.
I use these to circumvent Sky's stupid restrictions.
Worth a go.
Vpn? He will have to use vpn? Forever?, i believe your carrier is denying access due to fake id. . .return to yor real roots, or you will get troubles,
Example , is imposible, strictly forbidden change IMEI number of mobiles,
So i may able to SHOW a fake IMEI for really nonsense apps that NEVER interest my IMEI. THAN THE CARRIER.
The carrier, will recognize my real IMEI EVER.
If i change the code inside the IMEI,
They will suspend the services.
So. . .

They already have suspended his services and no he doesn't need to use a vpn forever, he can always update his plan.
What's wrong with a vpn anyway? I use one all the time and he only needs to use it for mobile data not wifi.
We're looking for solutions here to unreasonable restrictions not statements to the obvious.
Sadly what I use most of my data for is Netflix, I work as night security. A vpn would be bad.
To chap further up, nothing is spoofed at the minute, three detect the sm-t705 when I have thier sim in it and block data access, put the sim in my phone and the block is lifted, I'm looking for a way to make three think my sm-t705 is saying Xperia z3 and leave my data along
Your IMEI correspond to your device model number.
If You change or reformat your IMEI partition with a new number and device model number and id, the carrier will blacklist and suspend your device, simcard.
Is imposible to fake IMEI to carrier provider
I am able to spoof IMEI to all that i judge nonsense apos, minus the carrier...

Question Is this phone incompatible with others for transferring settings and data?

I have been having some trouble with transferring settings and data from myGalaxy S7 to this V+5g. The tmobile store said they'd do it for me, probably to get me to take the phone?
Then, they couldn't do it. They installed Samsung Switch and then discovered that they couldn't use it! So they tried transferring something via BT. Then they discovered that nothing would transfer, beyond one simple Google identity, which I could have set up by simply entering my ID and password. So they switched to plan B: Ignore me when I came in to the store to complain that I cant actually use this phone!
So they left me to complain by phone, where they could ignore me ad infinitum! For this reason, when I found out that I was locked into a 2 year contract with this phone I cant use, I put a complaint in to the FCC.
MEANWHILE I tried to install some programs individually. Firstly Doubletwist. Then I discovered some idiosyncrasies of this phone. I need to get 60GB of music onto this phone. But the music wont go onto the phone. Firstly, if I can get the phone seen by my MacBookPro (by enabling debugging, enabling File Transfer by USB and by starting doubletwist on the phone and computer), the music will transfer, excruciatingly slowly! And it does seem to go onto my 128GB SD card. But it does stop every two GB or so. Then, it simply wont restart. Nothing I can do will get the Revvl seen again by DT on the MBP.
Does anyone think that t his inability to get this phone to transfer data or files might be something actually wrong with the phone? I discovered that tmobile were thrilled to get rid of this phone (10 minutes before the Revvl VI 5G came out?) but I am not sure yet that a Revvl VI 5g would be any more compatible with my Samsung Galaxy S7 than this model V 5g? So I am wondering if this problem which I have had and which the Tmobile store also had is the same problem with the phone itself? Especially where the store were so insistent that they didnt want to help me. After which TMobile were careful to tell me that they couldn't take the phone back because I had got it from a store!
Since closed down!
Or has anyone else had these problems?
