[Q] Tricking the system - General Questions and Answers

Hello!
I am new to rooting my galaxy S3 device and I want to start off by saying thanks to all the developers that make owning a smart phone exciting again. I have an issue that I'm sure has been resolved previously but I have had no luck searching through the forums. I have a U.S. Cellular galaxy S3 SCH-R530U and I use my phoen for work applications. By this I mean that I have my corporate email and calendar syncing, which initially required me to give the application that controls the corporate sync pretty much 100% access to my phone.
When I first rooted, the application seemed confused and seemed to have issues which allowed me to continue using the email even though the company (they use an app called air watch) sent me an email about my device being non-compliant. There was recently an update for that software that would not let me continue until I updated. Longer story short, I used Triangle Away to try and fool the system that it was the original settings.
Is there a program that has been developed that will help me fool the program into thinking that my device is compliant?

Motorola Solutions TC55

Hello,
I have a TC55 from Motorola Solutions (i.e. the enterprise division that does not belong to Google). It is a rugged phone with a big battery (4400 mAh), but certainly not the sleekest design. Not sure if there is much interest in this kind of device, and I am certainly no developer - but in case anyone is investigating the TC55, here are two things I found so far:
It does not come with any Google apps: no Maps, no Gmail, no Play store and so on.
It is easily rooted with Framaroot using the Gandalf exploit.
(I cannot post this info into the Framaroot thread due to my low post count).
Anyway, maybe this helps someone. I will be happy to try to answer any questions about the TC55, but keep in mind I am no pro and I am not keen in messing around in its internals much more than I have done already.

I heard my company is planning to go with these soon for entry level supervisors such as myself. I'm trying to figure out exactly what it is. All the specs and brochures from Motorola keep calling it a mobile computer in a smartphone "form factor" but never actually call it a phone. I didn't see anything in any of the specs to lead me to believe for sure that it was a phone or if it was just an Android computer in a smartphone form factor.
Anyway, I just wanted to confirm, that, you're certain this is a phone, correct?
Thanks.

Yes, definitely. You can call and get called, and you can send and receive SMS. It also supports wired headsets, and it is supposed to work with Bluetooth headsets, though I do not have any to test.

Thanks for the info but it looks like mine is going to be crippled.
Sort of a let-down really. Yes, it "can" be a phone. Or without a sim card it can be a really powerful Android based mobile computer. That's what it is going to be for most of us. Only a few supervisors with area management approval are going to get units with the phone features working. Still cool. Just not as cool as I'd thought it was going to be.

I see, sorry to hear that. It sounds weird to me to do that, but then again I have no clue about this type of work.
Maybe the crippling could be worked around or undone by people with good Android knowledge - but I suppose it might not be the best idea to go against company policy.

I don't think they're doing anything all that special to cripple it. They just won't all have sim cards or a cell plan. Pretty much as simple as that.
I won't be doing anything to circumvent that though or rooting it or anything like that. It's not like it's a gift and it belongs to me or anything. After almost 22 years, I've kind of grown to like my job and getting a paycheck every two weeks.I'd kind of like to keep it for another 15 or 20 years. Who knows, maybe my manager will decide that I need cell service with mine.
I work for a large automaker in the U.S. We have over 2.8 million square feet under roof. Personally, I can be anywhere on in the plant, on the roof, in pits & sub-basements underneath or anywhere on or near the 50 acre plant site at any given time. A lot of what I need to do on a daily basis is through our intranet portal. They're putting in something like 500 new wi-fi repeaters/extenders all around the plant as well. They're purchasing these for over 300 first line supervisors at my site alone. I'm pretty sure they're doing this corporate-wide so I hate to think what they're spending on these things as a corporation. I'm sure it would bankrupt many small nations! In addition to giving us portal access away from the desk, these are meant to replace our aging industrial radio system. As expensive as these are, they're still much cheaper than $1.5 to $2k per person for a radio that has no other built-in functionality and these do seem pretty ruggedized.
Still a shame about the phone functionality though.

Can you see what browser it comes with? Can you install (untrusted) APKs directly without rooting it?
FYI, in case anyone's wondering, there is a version with Google apps on the way (if it isn't already orderable).

Browser is a standard one, which comes with other devices. Name is Browser.apk and version is 1.0.9
It's possible to install unsigned APK's without rooting.
google account
Hi,
I got stucked with trying to get google calendars from my google account to TC55.
I found one solution to setup google account as a corporate one, but it's not available anymore due to change in google policy.
I can setup google mail via email account, but that doesn't bring me my calendars to the device.
I tried to install gapps but without success.
Is there any other way?
Thanks.
Motorola work on google apps for TC55.There is in beta.

No idea, I haven't tried. As far as I understand gapps are usually installed via flashing a zip from recovery, and the stock recovery of the TC55 does not have that option, it only allows reflashing a whole image, if I understand it correctly. Either way, I have come to appreciate the open source alternatives and do not want to get Google on my phone, so I will not try, sorry.
However, going by this thread over at the Motorola support forum, it seems it won't take long until there is official gapps support:
https://developer.motorolasolutions.com/thread/4989
Motorola has now released a TC55-firmware with Google apps. Here are the release notes:
https://atgsupportcentral.motorolasolutions.com/content/emb/docs/ReleaseNotes/Release%20Notes%20-%20%20TC55_RevAPlus_GMS_01%2074G_v10.htm
According to the support email they sent me, to get the actual release you need to perform the following arcane ritual:
Resolution Type is : Software Download
Resolution Id is  : 95562
Resolution Title is : TC55 Update Image v1.74 with GMS (Google Mobile Service) Release Note & Factory Reset & Enterprise Enabler package
restrictedSW :
T55N0JGMVRUEN17400.zip 321 MB TC55 OS Recovery Update package
T55N0JGMVAUEN17400.apf 321 MB TC55 OS update package file for deployment using MSP
If you require access to OS files for TC55 1.74 GMS then call the local Support Desk and provide following information:
a. Site ID
b. Serial #(s)
c. Phone #
d. Customer name (First and Last)
e. E-mail address

Don't ask me what the local support desk number is, or the site ID, or why they have to make this so complicated.
Hi Elanguescence,
I think I screwed up my tc55 by enabling the multiuser function without first creating the white list. Now all the users (with admin rights) does not have access to all the programs, including Applock Administrator and Multiuser administrator.
To cut things short, do you know of a way to reset the device? I don't mind setting it to factory default and start over. I've googled it and some said to launch Rapid Deployment and scan a barcode from there... but my Rapid Deployment just says "Service Not Ready, Please Wait" and get stuck there.
Any help appreciated. Thank you.
Any TC55 users here? Should be getting my unit w/ GMS soon... How do you guys like it?
Is the bootloader locked?

Hey!
I want to Buy one TC55 for me. Normally i hate Android and the Google stuff on the Phone but some Motorola Salesman told me there is a version with out.
Now i use an Sybian Device. That mean i am "offline" the hole time and when i need Internet the Phone connect the the Internet.
So how about that phone can i work "offline" to?
I will also use an VPN Tunnel to block on my backend all Connnection i dont want. Does all Data trough this VPN Tunnel ?
How about the Barcode Scanning does it work good?
I know for 2D i need to use the Cam but how works it when i am in some other Application?
Nobody?
Ok. I just bought a TC55 from a Friend and I was wondering if someone would post the update to get GSM and the Factory Reset packages. I went to the page and it requires all the information posted above before. Mine is rooted, but i am trying to install GAPS but the recovery is the basic and cannot. I manually installed Google Play and the Google Play Services but Google Play services keep crashing and the Play Store will not connect, any ideas ?
the are 2 versions one with google s... service and the other without.
So i belive you have the first?
(Can i ask you some question about that phone?)

Have questions regarding apps and Google Play

A few months ago I purchased a product that included an android device that is used to operate the main electronic. I was having several issues with the main electronic and the android device so I began posting my concerns on a different forum that several employees of the main electronic frequently visited. I was told to return the electronic and everything seemed okay with the new product. A few weeks after receiving and setting up everything and update was sent out for the android device and the main app on the device used to control the main electronic. However, after the updates I began noticing features that I posted about were not working. I found this to be extremely odd and contacted customer service who just gave me the run around and told me to try downloading the app on a different device so I did and had the same results. I ended up trying 4 different android and apple devices, 2 of which I downloaded the app at home and 2 were brand new so I downloaded the app away from my house on public wifi. The 2 new devices worked flawlessly until I updated the app later on at home. Now if I remove the app and re-download it on any of the devices it won't work. How is this possible? I'm simply at a loss and need the app to work. The main android device that came with the product has the app built in so I rooted it and deleted the app but I'm still having the same issue regardless of where I download the app. At first I thought I was dealing with a virus but after downloading the app from other places I'm not sure. I desperately need some help from you guys getting something figured out and I'm sorry for being so vague regarding the product but I don't want to ruffle any feathers and just in case this situation can be used in a law suit I don't want to give out more information than what's needed. Anyway, how can they target me specifically at my house and how can I delete all the app information from the main android device and basically start fresh. I did use titanium to delete the app after root but I don't think it worked because after downloading it again I'm left with the same situation. Also while using titanium I accidentally deleted the update apk and didn't make a backup beforehand so I'm out of luck with that I guess unless someone knows how to get it back. Thanks and I hope to hear some input from you guys.

Kid's first phone to turn off internet connectivity (mobile & Wi-Fi) : Mod old Verizon Galaxy S5 or Gabb Wireless?

Experienced heartbreak in purchasing slider & flip phones off of eBay, which worked for seller only days before, but then learning that Verizon will not activate any new lines for 3G, slider, flip, CDMA devices. This has always been a great way to give kids a first phone, a phone that will only do call & text. So, turned to old family inventory or new companies that specialize in a modern phone with internet or social media interaction. Enter Gabb Wireless or Pinwheel. Landed on Gabb Wireless, but my bride wants me to try to mod an old Verizon bone stock Galaxy S5. Of course...& I'm sure many of you have been there...some guy we know was able to do it with his kid's phone...so now I should be able to do it. Never mind this guy is a software dev and most likely using an iOS phone. So, gauntlet thrown down, challenge issued. I've been doing a lot of digging & don't know if this can be done with this build. Here's what we have:
G900V, bone stock Verizon
Build number = MMB29M.G900VVRU2DQL1
Security patch level = 8/1/17
Let me know if any other specs would be helpful.
Thank you kindly.

Not sure why you don't just go buy a burner flip phone from Walmart? I thought those could still be activated.
If not, you'd have to disable the portion of the kernel that handles data. Let's be honest, this is a ~10 year old device so you won't find much assistance unfortunately.
Oh yeah, forgot, this is Android 6.0.1.
As for the query, you're right...I could do the burner/fip/slider thing, perhaps...but, truly, it appears all carriers across the board are throwing off 3G devices as fast as they can. I did see some of the rough service basic phones have 4G capability, but can't justify price on those things. Tough balance to strike as we're doing some traveling where VZW is the only network that's really reliable...& trying to get a child the best camera possible on the devices we have, so they can take pics of stuff they may never see again. Old basic phones are pretty challenging to text on, too. Anyway, we have an old iPod Touch someone threw away, plus the S5. S5 has the better cameras. But it's one of the last builds they sold for Verizon...and I don't ever remember there being a way to unlock the bootloader on that build...the G900V. But, regardless, I still can't find a way to shut down mobile & Wi-Fi on it. I think they have a Verizon family app that will let you shut down the web, but it is extra per month, of course. Appreciate the feedback, for sure. This is just the DIY kinda life, I reckon: constantly trying to refurb, reuse the old stuff, fix stuff yourself, do without...all to live w/in your means & save dinero.

I mean there is a way to unlock the bootloader if you look on XDA. https://forum.xda-developers.com/t/...ootloader-using-dev-bootloader-kk-mm.3337909/ The Verizon S5 was the worst model out of all of the US carrier variants.

I know this thread is almost a year old, and I'm sorry I'm late to the party, but I had the same idea!
My kids had been using Gabb Wireless for a while, and we were mostly happy with the service, but I wanted the option to install other useful apps on their phones without giving them access to the web. So, I bought a couple of old Galaxy S5 SM-G900V (Verizon version) phones, and I think I've succeeded in modifying them in a way that will prevent the kids from surfing the internet or installing their own apps. I thought I'd post my method here, in case anyone is still interested. Here's what I did:
Install Safestrap Recovery. (Follow this guide, up to and including the step where you install Safestrap. Skip the remaining steps in the guide.)
Boot into Safestrap Recovery and flash jrkruse's “slightly de-bloated” stock Marshmallow rom from here.
Use either ADB or Safestrap to remove any system apps that would allow kids to browse the web or download their own apps. (To delete unwanted system apps using Safestrap recovery, click Mount and make sure the system partition is mounted. Also make sure the “Mount system partition read-only” box is unchecked. Then go back and click Advanced > File Manager, and edit or remove system files as desired.) The web browser is already removed from jrkruse's rom, but I also removed the following apps:
from /system/app:
Gmail2
SamsungSetupWizard
SecEmail_K
InteractiveTutorial [This is the Samsung Help app.]
SamsungAppsWidget_Phone_Carrier_VZW
from /system/priv-app:
Velvet [this is the Google search app]
SamsungUpdates [this includes the Samsung Apps store and “Galaxy essentials,” which would allow kids to download and install their own apps]
GoogleOneTimeInitializer
SetupWizard
from /data/app:
com.android.vending-1 [this is the Google Play Store]
Edit the settings APK file to disable the option to remove the option to install apps from “uknown sources” (Settings > Security > Uknown Sources) so that users can’t enable that option. This will prevent kids from installing apps by sideloading (e.g. copying apps from a friend's phone via SD card.) Apps can still be installed via recovery or ADB, but most kids won't know how to do that.
To edit the settings APK properly, you could follow this guide, but I used a much hackier method and basically just sabotaged the security_settings_misc.xml file inside SecSettings.apk, so that the settings app crashes if the user tries to open and modify those settings.
I've attached my modified settings file. You can put it on the phone's SD card, then use Safestrap to copy it to system/priv-app/SecSettings. Save the original settings file first (or just rename it and change the filename extension) so that you can restore it later if needed.

Is my Girlfriend is a computer hacker?

Hi, I am not new to computers phones and development but it's been years and a lot has changed. I went to school for software design and I learned on Visual Studio 6.0. So for anyone in there 30's and older you all remember how 6.0 was. Well alot has changed since 6.0 but regardless I know when someone has been messing with my phone a s or computer. I am going to try and post all of my syslog that I have saved and any new that I see. Also ibam going to try and post what open source software that I notice my phone now has licenses for. I am on a Samsung Note 10 plus 5G. And I am almost positive that my girl is responsible for the modifications done to my phone but she screams that she only knows how to play games call and text. I need someone to review my information and any information that anyone needs and tell me if my phone has been modified and if everything could have been done remotely. My ultimate question is could this all have been done remotely or would any of it and I mean even the smallest thing have to be done locally on the phone. If every single modification could all have been done remotely then maybe she's telling the truth but if just one thing had to of been done locally then she's responsible somehow. And then I need to know how to fix all of this and set up secure to prevent it from happening again.
you claim you're developer but provide logs as screenshots... seriously, if you can't trust your girlfriend what you need help is a couble care course or psychotherapist.
I doubt your Samsung Galaxy Note10+ bootloader locked device secured by Knox is tampered in any kind at all
What i'm seeing here is you using your phone with samsung packages working. It's mostly sounds running, you unlocking the device, setting an alarm ect.
Bare in mind google and apps use location alot so the location is i would say the norm. The more apps the more times location is called.
if you are concerned get dmr checker and check security levels, has the device been rooted and displays the true code? Really worried check all your apps then disable location or use odin to fully wipe the device but from what i can tell this is possibly paranoia
Whether your girlfriend can be trusted or not is not the problem. Maybe she is really hacking your phone or maybe you are just paranoid, I can't tell. Either way you two should break up before you break each other.
.. or just a week digital detox

Question FRP Lock on A22 5G

Hi folks,
a family friend inherited an A22 from a deceased friend, but she did not have the password for it.
As I had never heard of FRP before, I advised her to reset the phone, which is how the FRP took effect. I now feel guilty for giving obviously wrong advice and would like to fix it.
I guess there is no proof of purchase for the phone anymore and all the passwords from the documents didn't work. A Vodafone employee advised me to scrap the phone, but I don't think so.
I found the software "**** your FRP" here in the forum and tried it, but the A22 is not on the list of Knox-compatible devices. Therefore, the code #*0#* does not work either and I can't get any further.
I got a little further with the talkback function. I was able to open the Google Assistant and navigate to Chrome or the settings. Unfortunately, I could not activate the developer options, couldn't navigate to the app settings or allow the installation of apps from unknown sources.
After about 8 hours and several attempts, I am at my wit's end. I have the deceased's email address and name. Unfortunately, this was not enough to reset the password. If I am informed correctly, his number has also been deactivated, so I can no longer receive SMS. I don't have the SIM card either, but I might be able to get it.
I hope you guys can help me.
Best regards,
Felix
Contact Samsung service / a phone service.
You could so it yourself, but the time needed will be too much
As I said, the people at Vodafone said you can only scrap it. I had read that you can get the device unlocked with the help of the proof of purchase, but no one knows exactly where the receipt could be.

I'm not in a hurry, I'm just looking for a tool to do this with, or instructions on how to bypass the FRP.
I can forget Google, as 99% of the results are scam and the remaining 1% did not work.
Ive heard that YouTube has just the right type of guide for almost exactly those probs, and by all accounts very very simple to follow, as I did recently on my sister's device she left at home, no longer wanted, ditched for an apple contraption. I will add, no one with nefarious reasons, stolen devices should use the helpful tools there. Getting a job and buying a device the bloody deviants should....damn the swines.

The problem with YouTube videos is that Samsung (and pretty much every other major manufacturer) has teams of employees whose sole job is to look through the internet for how-to videos and posts, make a note of how the trick/bypass works, and submit it to the software development team to be fixed in the very next update. That's why the how-to videos are full of comments saying "this didn't work for me" or "I don't have that option on my device".
There's a professional 3rd party business that I've used for things like this before. Discussion of paid services isn't allowed in the forums, but anyone who wants a recommendation can DM me
I completely agree mate, it's hit and miss, there are plenty of other sources out there. Just coincidentally, I found myself reading a comment that was the exact situation I was in yesterday. Obviously, not wanting the member to be struggling I gently nudged him towards a simple and 100% idiot's guide that will put him right. Admittedly a large majority of these things are countered/blocked or absolute bollox as I have encountered many times lmfao

Also mate, getting to chrome is most of it done. 4 files to download, 2 through the galaxy store which allows them to install, then through those, sorry, plus ios14 launcher allows you to activate unknown sources etc..it's not difficult. Worked like a charm. Just find the Samsung a22 5g frp unlock, activate unknown sources how to.
