[HACK][4GHOTSPOT] 4G router as wifi hotspot with good battery life suggestions - General Questions and Answers

Hi Guys,
I am trying to have a good 4G wifi hotspot, please share your thoughts?
Some requirements:
1) I want to have a full control over the device, if able to run a linux directly will be the best or some kind of router linux, which can setup firewall , VPN etc on it.
2) Good battery life, like able to have 15-20 hours usage time.
3) Not too heavy, less than 250g.
4) Cost less than 150 USD.
Some of my thoughts:
1) Have an android phone which was able to be hacked to have full control(run linux directly etc), turn it into a 4G hotspot only, and remove the screen connection to save battery(no need to have a display).
2) Using something like "GlocalMe G3" or "GlocalMe U2", and have it hacked to have full control. (I have the U2 device, looks like it is using MSM8909, and running android, but I am not able to hack into it yet, may need some helps from you guys).
PS: not able to post the link, pls try to google "GlocalMe U2" if you want to learn more about the device.
Thank you for sharing your ideas.

I bought a device called a sapphire touch which appears to use the exact same hardware as the GlocalMe G3, I took it apart and got some pictures of the hardware and am interested in getting a better rom installed or see if I can side load some apps.
Info and pics here, please add any info, would to be able to get developer mode enabled and install a custom boot loader to start.

htc evo root and wireless tether

Hi wondering if its possible to root and use wireless tether for the new htc evo. I see they have the hotspot installed but its a monthly fee service. Can I use the wireless tether like I use to on the hero?
Thanks
much like sublimenal above, I'm new to XDA, and I'm jumping in because this is the place to be for the How-to.
Can someone direct me as to where to read up specifically on the the EVO root and tether process? Am I jumping the gun, and there is a walkthrough in development?
Regardless, thank you ahead.
Hey there, actually i just did it yesterday. It was extremly simlple, nothing like rooting the hero and took me about 3 minutes total lol. Here is the process.
1. on your phone go to http://unrevoked.com/m/
2. download the apk file
3. install the apk file and click start
4. you are rooted!
5. go to this url and scan the code with barcode scanner http://code.google.com/p/android-wi...name=wireless_tether_2_0_2-pre14.apk&can=2&q=
6. install the tether app
7 run the tether app and your solid!
foserious? Man! THANK YOU!
I'm gonna do this right now!
Yeah I couldn't believe it, the hero took me a few hours to figure out how to root/tether even with the tutorials. This was extremely simple, i guess it works for the hero as well but only if you didn't install the 2.1 update.
man, thank you so much. Everything went awesomely.
Now it's time for me to donate to these code commanders.

If you want to install custom roms dont use unrevoked root.
whats wrong.
Why is everyone's evo working on tether and mine i always have problems.If its that simple i would think mine would work.I got tether running and says limited connectivity on my laptop.Also i downloaded the tether on the market place.Could that be the wrong tether...??
please check your tether log, and post any pertinent info.
Also, does your laptop identify the connection as Ad Hoc? What IP does your laptop get if any? Are you using any features with tether like WEP?
Details plz.
Thank you..................
I want to thank everyone that has helped me figure everything out.Just a few things i need to know.
1. Can sprint find out your using tether?
2. Are there settings i can adjust so no one can use tether but me?That way not anybody can connect to it?
3.When using tether,is it best to turn on 4g or is it okay with 3g running?
4. Can i connect more then one device using tether??
Thank you all...
Step 5
Ok i clicked on the url to scan the code and the page wont load. Any suggestions, or maybe different link? I got a 502 server error.
please help..newby...
hi all..please dont be hard on too hard on me for not being a "tech wizard" but I have a couple of questions..I just bought the EVO and I am new to android OS I have always been a windows user so I am pretty clueless on how the android operating system really works my main concern is being able to tether with the EVO with my TP2 I was able to use walking hotspot which now I cant use with android and pda.net which I cant use with my Ipad unless my android device is rooted.can someone post step by step instructions on how to "root" to be able to tether and also if there is a way to "back up" my info just incase something happens.and what to do if I want to restart the phones to the original factory settings just incase I decide to return the device within my 30 day trial..I am hoping all the battery tricks work and I am able to tether with out a problem if not this baby is going back to the store..thanks and I apologize in advance for my ignorance with this topic.I have owned windows mobile devices since it was first introduced so I am clueless to anything else
I'd start by looking in the correct forum or using search.

Sprint monitors data usage, however if you look at your bill the extra $10usd that you are paying gives you unlimited data usage on 3g and 4g. Just be aware that Sprint has reserved the right to throttle down your bandwidth.

Ubuntu 11.04 advice [found related]

EDIT: Nevermind, while in the process of editing this post to narrow its scope I found a related post to watch. Thanks to readers. http://forum.xda-developers.com/showthread.php?t=1062348
Anyone here using Oneiric with their sensation have any advice for better compatibility?
I just recently upgraded from a W755 and have been running into a few troubles. A couple things I'm wondering:
USB tethering. I see options for both making the internet available to my phone from my computer and from my phone to my computer... I can't seem to tell if either are working. Anyone able to get these working (in linux/ubuntu w/unity)? (Haven't tried wifi hotspot but am guessing it works fine).
Management programs: Is there anything which allows easy management of phone information from a linux os? I had to work for 5 days to clean up all my contacts between duplicates, missed links and other problems. Would have been much nicer to do with some form of management interface on my laptop.
Other: In general could anyone offer up any advice for either a new smartphone user running linux as their only OS or things to watch out for? I'm already eager to see what cleaning up of the bloatware I can do when the thing gets unlocked (The fact that I can't uninstall a crappy bundled FPS is stupid).
Thanks in advance,
Garrett

[Q] Using hosts.allow and hosts.deny

I'm contemplating getting my 14yo daughter an Android phone for xmas. I want to be able to restrict internet access at the OS level. I've looked into the parental control apps but all of the ones I looked at are pretty easy to circumvent. I figure using hosts.allow and hosts.deny is a better solution (i.e. hopefully take her longer to figure out) but from what I can determine, Android by default doesn't use these files.
Does anyone know of a ROM or kernel that does use these files a la conventional linux?
If not, what are recommendations for restricting internet access?

[Q] Any WP7 Device as wifistick for PC´s

So here is my request and pleed:
Please create anyone an app which is possible to change the WP7 Device into a wifistick,so that you can connect your pc through your Phone to your wifi,this would be absolutely great,and if it is not possible to create an app for me and all the guy´s who have requests for this missing feature because of time,or other reasons than impossibility then please tell me anyone of you how the code must work,which api´s and so on i´ll need so that i´ll be able to create such´n app by myself,because i´ve visualstudio and can do some programming
thx for any answer
What Phone do you have ? Is it unlocked ?
The app "Mango Webserver" (in dev & hacking sub-forum) can already kind-of do this, because you can uload files using your web browser, then download them later on another computer.
If you want to create an app that is dedicated to the purpose, the first questions would be how do you want the PC to see the phone (using a browser like Mango Webserver app, or using a dedicated program, or what) and do you want this to be a marketplace app, or is using unofficial APIs OK?
So i have an unlocked Omnia 7(fullyunlock + interop(it is really interopunlocked believe me,don´t ask)) ,the way i want to use it is like a wifistick/modem or so,if it is unofficial or not therefore doesn´t interest me,but i thought that it eventually would be able to get this feature for more devices,so that it would have some more attention as only for samsung devices
so thx again for any answer
Hmm sorry, I misinterpreted your request. You want to use the phone as a WiFi network interface for the computer. ("wifistick" doesn't mean anything to me; never heard the term before.)
I don't currently know of a way to do that. You can use your phone to connect the PC to the Internet (using wired tethering), but that just turns the phone into a cellular modem. To do what you're asking, you'd need to either bridge the WiFi and ethernet-over-USB connections, or you'd need to set up Internet connection sharing between the WiFi and USB (like the official "Internet sharing" feature, except that one is between the cellular radio and the WiFi).
Yeah thats what i mean,but i think it must be possible anyway,because for wm devices that was available and also for androidphones such a function is available,why shouldn´t it work with wp7 devices?
Oh, it's possible. You'd need to use native code and probably need to have more permissions than a normal app allows, though. Just because an OS *can* do something doesn't mean that the software to do it is available.
I already listed the two most reasonable approaches to doing it. I'm not sure if WP7 supports connection bridging, so the first might not be possible. The second certainly is, though.

NO MORE SLOW.

For the few who remain using these tablets (and the even fewer who bought a 2015 shield controller like me) I have the final nail in the coffin for performance. Without custom OS. Allowing you to use your very specific (criminally underused) 2015 Shield controller wirelessly. Welcome to the end of your woes (performance not guaranteed, this crap worked for me though). I still haven't checked if battery usage has improved, but it has certainly let me depend on this and use my controller again as opposed to using a CustomOS (previously used AEX 6.7, good performance, but bad video playback and lack of wifi controller support).
Required thingys:
TWRP
This awesome script (JournalingDisabler.zip) (thnx very much skynet28): https://forum.xda-developers.com/t/...urnaling-in-internal-ext4-partitions.1252028/
Developer Options
Snacks? Drinks? This is gonna take some time, don't pass out halfway through lol
Boost 1: DISABLE JOURNALING.
Y'all. This is the good stuff. the nitro. This will make your tablet feel new (again, if everything goes right and I'm not some insane fluke). I only got the idea from an offhand comment from m0nt3s. I thought they were talking about one of the writing apps at first, but once I learned what it was, my brain imploded. Did a quick google search, and found skynet28's solution right away. It's a script designed to disable an ext4 logging service that eats up memory and processing power. I didn't think it would be compatible (but my chaotic neutral mind said why not), but it works:
1. Install TWRP using adb and prayer (that's what it feels like the first time around lol)
2. Download the zip (JournalingDisabler.zip) to your tablet.
3. Use the install button in TWRP, navigate to the zip, and install away.
It should show text saying journaling is disabled if all went well. The gains should be immediately noticeable on your next boot. I didn't notice any issues or side effects, but I also have the benefit of not having important/sensitive data on it, so just to play it safe, back up your data in case issues crop up later.
Boost 2: BACKGROUND PROCESSES
This one will be a touch more noticeable, especially if you multitask on this tablet, but it can definitely stop a lot of the hitching. This one will be in the bottom of the developer options. If you don't have dev options, go into the about tablet section and tap the build number until you become a dev. Setting it to 1 or 2 is decent, but setting it to none will have the biggest impact.
Boost 3: DON'T USE APP OPTIMIZATION
Seriously. Don't know who dropped the ball. But just turn it all off. It's not even a boost, it's just a negative having it on.
Boost 4: SYNCING
If anything is syncing, be it Gmail, your YouTube notifications, or a news feed, turn it off. Any time apps struggle and fight for WIFI, your experience sucks. If you aren't using it as a main (i'm using it in my car as a head unit)
Boost 5: Color Correction
Must have been the same peeps who dropped the ball on app optimization. With the gains you get above, you might not need to, but if you're trying to max it out this will do it.
That's it for me! This is what I've done to get my tablet feeling smooth again. Let me know how it goes?
I can attest that a lot of the above is what needs to be done to save the last days of this tablet. I did not now about the journal part- will have to try this. Related, I just flashed the original OTA's for the Wifi edition on my Shield LTE. By doing this I got a insane boost in battery life. The LTE (H+) does not work but I don't need it and there are other devices that have much better connectivity .

This works! Every bit of OP is legit.
I used current TWRP as of today, twrp-3.6.1_9-0-shieldtablet.img, from https://twrp.me/nvidia/nvidiahshieldtablet.html using fastboot install method on a fully updated Android 7 Nvidia Shield Tablet model p1761w.
Thanks, much respect!
It is important that those who still do not install TWRP should know that to enter fastboot, they must use the official nvidia drivers "SHIELD_Family_WHQL_USB_driver_201801"
This method helped me to lighten but it becomes impossible to install applications, the google services together with those of nvidia cause the ram to collapse and the system cannot manage correctly.
I strongly recommend you to change to a custom rom, you will finally feel the fluidity of the system
At this moment I use lineage 15.1 (android 8.1) + google services minimum (pico)
No chrome app - no Gmail app + facebook and instagram full app. and the system remains light.

I really wish a developer(s) would take one more look at this device. If there was way to bump up the android version but retain the NVIDIA features it would breath a few more years into these . These tablets are still pretty good for mid range emulation and now that everything has changed with cloud gaming, they are not as irrelevant as it would seem . I've been having pretty good performance on my LTE 32GB that I flashed the original "WiFi edition " stock ROM on. I get great battery life now and use the tablet almost daily for gaming and light use. The sound is also still pretty impressive and I like the stylus functionality as I can't really afford a Samsung device.
What is "journaling"? Is it the same as the logging by logcat? You can set the buffer size to 0K or 64K (setting it to 0 still logs at 64K).
