[Q] rooted android device - General Questions and Answers

If i have a rooted phone and install say ubuntu would i still be able to use it as a phone? i have been considering installing a different flavor of linux on my phone for a long time but that question has always stopped me. Now why i haven't asked till now is beyond me honestly but i would really like to hear input from someone that has install a new OS on there phone.

Hi, it depends on which model your phone is, and what custom OS you want to install.. for Ubuntu Phone, for example, you can check the development status for various device at this page.. https://wiki.ubuntu.com/Touch/Devices
If your device is listed there, click on the status link and there you can see which parts of the OS work and which don't , there is also a Phone/cellular section.
If your device is not listed, it means tha Ubuntu Phone cannot be installed at all.

Nextbook Next7P YF0511 series dmesg

Hi all - newb here, first post. I just picked up a pair of Nextbook Next7P tablets off eBay, cheap. One is stuck in a bootloop at the poining finger screen. It doesn't get past this screen, and when the spinning logo stops, then it just starts again, and just keeps repeating this action. The other had a black screen, and thankfully, I had already read in another post in these forums where someone suggested using a LED flashlight on the screen. I was able to see the clock on the lock screen, found the unlock icon, got it unlocked, and eventually found my way to the screen settings, and was able to adjust the backlighting. So now this one tablet is working normally.
Yesterday, I hooked this tablet up to my laptop, after setting the USB Debugging on. I was able to "pull" the system folder and the data folder, so those are now copied to my laptop. I also used the command:
adb shell dmesg > dmesg
I have attached the dmesg file here.
I don't know how to get out of the boot loop on that one tablet, and I think the answer is that I will have to load a new rom. However, since my serial number starts with YF0511, this means my tablet is an early one, and the roms do not work on this tablet.
So my goal here is to find out what specifically is different about these early models, and maybe we would be able to develop or mix a rom using the kernel or modules from this rom, and putting them into the rescue kit, or into a rooted rom.
Maybe someone with a later model could use the adb and post their dmesg file, and we can compare to see what's different. In the long run it will benefit all of us who have early tablets, we could upgrade the roms and maybe even get ICS going.
Update ...
I've made some headway since my last post above. I found a rom for the YF0811 serial number range by Finless, and I decided to go ahead and try this on my boot looped tablet. The rom worked, and appears to be the same rom as my other tablet, which is the original stock rom - never been updated.
So although my original intention was to get some kind of rom development going for the YF0511, there is really no need to do this, the YF0811 roms are the roms to use.
I have seen many posts by people with YF0511 serial numbers, and in virtually every case, they were stuck because they couldn't find a rom for their serial number range. I do hope this will help someone get their tablet working again.
help please

hello,
I am using next 7p with serial number YF0711 since I bought it I tried to unlock it but all effort has failed,can you please tell me how to unlock it and which rom to use? my email add is [email protected]
khalifat, if you check over on the freaktab forums, in the rom developers kitchen, there are some nextbook roms by Finless Bob. If you go there, you will see in the list Nextbook 7 Premium #0811 Custom Rom with Market 3.4.4 by Finless Version 1.4. I don't think I am permitted to post a link to that.
Anyways, if you get there, that custom rom should work for you. There is also on the same page, further down, a #0811 stock rom. The stock rom will also work, but of course will be lacking in any enhancements.
I have run both of these successfully on my Nextbook 7 premium, with serial YF0511... and everything was working, including wifi. I used the stock rom to get my tablet out of a boot loop, then I tried the rooted rom.
Edit: the rom download contains the rockchip flashing tool and instructions.

[Completed] [Q] Several general questions about custom recovery and roms

Let me start by saying I am not completely new at this now and have unlocked, rooted, and installed some custom firmware (or is rom the preferred term?) on a few other more popular brand devices. Being as they were popular that made it super easy to find information, tutorials, and files. While I understand the basics of all the things I was doing and have learned a lot about using ADB and fastboot for instance I am still a bit lost on a couple key items.
So I recently however bought an iRulu V1 phone off of Amazon. While I was able to resolve how to root the device, which I can post about if anyone is interested, I can't seem to find enough information about custom recovery and roms. So here are some basic questions I have, which again I guess I should know since I dove in head first on my other devices, but I am still not sure when it comes to these things and really should understand them
1) Do I need a version of CWM or TWRP made for this device specifically or is there some generic that works for any device?
My device came with KitKat 4.4.2 no upgrade available form manufacturer currently to 4.4.4 or any update for Lollipop. I would love to install the latest version I can of course.
2) Similar to question #1, Is a custom rom needed to get any higher version of Android or can some generic version be installed?
3) On both question above, where does one begin to locate these generic or standard versions?
4) If there are generic versions of the recovery and/or Android rom, What are some of the caveats I might run into using them? More meaning what features might simply just not work?
5) I cannot find an image of the rom included with my phone from the manufacturer, What application or process could I use to be sure I have a complete backup I could restore should I do something stupid?
I tried an ADB backup and the image it created seemed way off in size even though I was using what I thought were proper parameters to get everything including the system.
I really have these questions as I still think of Android like one would of Linux for instance. If I have a computer Linux can run on, I can usually find a very generic ISO to get the OS installed and customize from there. I guess that is really what I am trying to do here, get as updated a version of Android as I can and then make everything work by loading modules or drivers as needed. I guess finally, Is that not really how it works with the Android OS ?
thanks so much for any answers or insight. I have thus far like many others found the info here invaluable while playing around with my various Android devices I have. I hope too that my post is falling into the proper format requested by this section, apologies if not.

Hi, thank you for using XDA Assist. You're right, there is no information about your device on XDA. In general, only flash recoveries or roms that are specific to your device. There are no general ones. Flashing something that is not specific can brick your device. Your best bet is to ask specific questions about your device here, http://forum.xda-developers.com/android/help and hope someone else with your device can help.
Sorry I can't be of more help.

Revive Soft Bricked Device through Identical 2nd? (LG l21g Destiny Tracfone)

Long story short:
How do i get my current working android device to revive an identical soft-bricked device. More challenging than you think: there is no boot menu accessible in the devices. Which means the only other choice is to use a usb connection to a PC to perform all tasks, i.e. create a rom system image backup of the working device, then use that to restore the system onto the soft-bricked one.
So is there a way to revive the s/bricked device with a rom image of the working twin?
The long story:
After using the super-sume app, my device got softbricked. Phones of my type are uncommon and are therefore not worked on by the android hacker community as much as flagship devices are. And little is known or discovered about them. So after doing more research, i've sadly come to know that there are other users here and there, having suffered the same problem as I. But enough about that.
As far as i've read and come to understand, i would need to re-flash the firmware to bring it back from it's softbrick issue easiest/safest way.
Though am not sure how the android platform would work. With PCs, i could restore a messed up system from a cloned image. What i need to confirm is if the firmware is separate from the OS (roms i believe) the same way device drivers are separate from the windows OS on PCs.
So am not sure if flashing firmware is enough and would need to stock rom too. Or is the rom considered both firmware and OS all in one?
I mentioned "restore from a clone image backup" because I have another, exact same model of my softbricked device, that functions still properly.
So i wonder if there is a way that i could use my working device to revive the soft-bricked one. In the sense that i would need to make a system image copy of my working one, to restore onto the s/bricked one.
What the problem looks like when starting the phone:
As for the softbrick appearance, the phone boots into the LG logo screen and is frozen there. It doesn't quite look like it's boot looping since the screen Never fades to black quickly just to come right back. It's just frozen there. This recovery mode screen is the only other thing i can get to besides the frozen LG screen: https://wcrates.files.wordpress.com/2015/03/lg-g3-recover-mode.jpg
I've come to learn (but may need correction on) that Tracfone devices are deliberately handicapped in a way i've never seen before. That is, their devices have no other boot type of menu besides the Recovery Menu (found before os begins boot) that is basically a factory reset. It just deletes all user data and resets system settings so that the phone works like it would at first when right out of the box. For the s/bricked device, that screen can be accessed, though executing that just resorts to the frozen boot screen again. If there is a boot menu to backup/restore from, clear cache, install from zip and what not, then please enlighten me. Because as i've tried everything, the tracfone-devices have nothing compared to non-tracfone-devices
So in order to install an updated rom, i may need to get into a type of system boot menu from where i would be able to select the option to install a rom or update it and what not. To some degree i assume that connecting the device through USB to a computer, one may do the same rom installation action through the PC, but it's in cases like these where i would need the help of and expert's first hand experience with such things or ways.
I don't mind if you want to leave a link to some tutorial some other guy has made that may closely related to (if not exactly) to help solve this issue. But i do prefer to get into contact with someone who i can report to with how the solution process is progressing. Mostly because me being a noob at this point of my android experience, but am confident since i've done this with pc's a lot.
I'm still trying to figure out what most of the android community speaks of when it comes to methods of backing up their stock roms and what kinds of software on PC or apps on the device are needed to accomplish a worthy backup. I do realize i'd need ADB and what other LG device compatible PC software out there. Here is a link where i think firmware files can be found, but since it's all in Chinese, i'm not sure how reliable the site is/can be. It's been about a month since i contacted some of their users. At this point it seems like they're no hope:
http://mobile.gaodi.net/Firmware-669539-1-1.html
I hope that i can find success so that i can post it up to help others who are in the same situation as me, and also for the many more who may yet fall into this situation.
Any help will be greatly appreciated.
Thanks.

[Completed] Wacom Cintiq Companion Hybrid ( DTH-A1300L ) android needs custom rom or stock bad

I have a Wacom Cintiq Companion Hybrid ( DTH-A1300L ) android version needs help in so many ways. I bought it because I really need one for one of my jobs, yet can't really afford the crazy overpriced insanity that is a new Wacom so the reason it was so cheap was "can't connect to the Play Store. I know, hella foolish, I thought I could fix it by rooting it, but this thing is like level 10 as there is so little info as no one wanted to touch them it seems. I did find one guy on this forum that at one point rooted I am fair to average at rooting and the understanding of all that surrounds it. I have happily and successfully rooted my phones and tablet but I am no pro and fairly good at having gaping invisible holes in my info or logic when it comes to things like this.
Most frustrating is this thing is stuck on android 4 . 1 . 1 for no good reason I can imagine. It has dev tools installed after factory data reset but no google apps. (It arrived factory data reset)
I tried the relevant framework and store and the delete the cache trick to no avail. It can not update and can not even get to the Play Store.
Sooo the bad news is; no Google apps. No updates offered and stuck on some weird what looks like not stock version of 4 .1 .1 Jellybean.
When I plug it into my PC via USB it does not even show up in device manager.
The good news is I rooted it. Checked with root checker (unfortunately for now its Kingroot)
1. I have no idea how to make a back up from here. (no USB connection to PC issue)
or
2. what rom will work as my device is not listed on any of them. It would be great to find the stock rom as I am afraid this things cool and weird cintiq mode, pen function like abilities may be disabled or rendered useless with just any android rom.
Is there anyway to somehow find the stock OS on my device through boot loader? A place to find my stock or like rom. A clever work around?
Thanks in advance. for any who take up the challenge and offer any help or thoughts.
Cheers

Excuse my noobness. Flashify looks good, I installed it, but don't I need some image from somewhere either the stock OS or a new one for it to work? Not sure how to get Gapps from there.
It did I think, find something, a "restore kernel" and "stock recovery" I am unsure did it find my stock kernel and recovery and or ROM and I should boot from that? ( again apologies a-lot of new info and its getting a bit swirly) In otherwords since my device is not listed any where and at this point any working Android version will do, I am wrong to try and reboot from this? These devices are supposed to come stock on 4.2.2, so I am hoping perhaps incorrectly it will go back to that? That would be ideal at this point.
So I can work again whatever works.
Also I a bit concerned about the "date" I posted from on one of these. I think I posted from the Wacom. Perhaps the problem in deeper than I thought as that is Linux time 0?
I think it self corrected but originally it said I posted on Jan 1 1970...
As for custom ROM, I probably wont be able to make my own custom ROM, even though I would love to take to the time to learn, for now I have too many art and work related deadlines.
I was hoping for one that already existed that would work with my device.
Perhaps I misunderstood something about how all this works? Also I do not have Unbuntu. I should as I support an open internet, but WINE really does not run the Adobe products I need for work so
I am stuck with Windows.

If you just want to be able to install apps from the playstore then this is a simple alternative
https://www.xda-developers.com/unshackle-your-device-from-the-google-play-store-with-apkupdater/
If your phone is rooted then flashify can flash zips like gapps without the need for a custom recovery. If you are serious about trying to make your own rom/recovery then use a virtualbox in windows. http://www.osboxes.org/ has plenty of prebuilt virtual linux machines that will run on windows
Regards

I appreciate all your help. I got the "google of every kind from Gapps on has stopped" is over, which was intense as it popped up every few seconds, I somehow got that to quit by reloading the proper one from the APK Pure app which was an odd work around but nothing else was working. Still have this unsettling bare bones screen and none of the stock apps as well as it being stuck in 4.1.1. This device was made for 4.2. and I assume it was on here at one point.
I wonder if that alone could cause hardware issues. I thought about taking out the battery, until I realized that thing is inaccessible as a thing can be without wrecking the industrial glues and taking the entire thing apart which sounds
like an accident waiting to happen and possible making things worse. I imagine that is last case scenario.
Like I said I would love to make my stock reload, at this point that would be great as this thing seems unstable and no trick makes the play store work or allow me to sign into the device with my google email.
I think you are saying to make my own recovery/ROM of my own device I need to do the virtual box thing. Correct? Or is that for writing your own custom ROM? I can try that; make my own recovery that is, as it is not on CWM or TWRPs supported devices list so I have no choice and all in all would prefer the thing to load as if it was fresh out of the box not this 4.1. One serious hiccup I have found trying to use my PC is my device is not recognized as a storage device or otherwise. Not sure if this is due to the weird settings of Cintiq mode or simply because the thing is in a very weird state of 4.1.1. So that may make making changes via computer impossible. I am not the type to give up. Thanks again Saw
Here also is a sum up I added to a the just basic question of Can you find the Stock from a recovery device. Basically is there any way to return a device to stock with no ROMs available to do so, as in extract if from the device itself.
Additional backstory if helpful.
"I have a Wacom Cintiq Hybrid running Android 4.1 that is ( now ) rooted..
This is a very bad thing. The Real Stock ROM has palm rejection and all the drivers to make it work as a tool. So stock is the ideal but it is clearly not stock as my device supposedly came in the
box running 4.2 and with software and drivers to make it work properly with the pen. This has nothing. No software and the smallest amount of apps possible. Worse this is no custom ROM its on ( I think) as it would be the worst one ever and it was not rooted on arrival. I have no idea what happened before I got it. I may have made the mistake of rooting it really as I found out to my dismay there is no ROM support. So back to square one. I bought it ( very cheap for one of these ) "stuck and unable to go to the play store" and I did not realize until I got it, on a version of Android it was not meant for. Wacom is totally and woefully unhelpful in every way. They seem to want to quietly put this device behind them at the expense literally of their customers."

QS5509A (Axia from AT&T) Boot Help

Hello, I just got a new phone. It's probably my first actual phone in many years, as I'm mostly a PC kind of guy. I have been having trouble getting it booted for a while now. Someone informed me that it might be an Axia phone from AT&T, but I don't know the validity of that. It says Q-Innovations every time I use it on Google stuff. Does anyone here know of the phone or know how to boot one?
Thanks a lot in advance!

The model number seems to be the AT&T version of that phone.
When you say that you can't get it booted, what do you mean exactly? What is the device doing when you try to boot it?
Have you tried holding volume up+power(let go when you see the splash screen) to boot into recovery, then factory reset and wipe cache partition?
Some devices have to hold volume down+power, then at the bootloader menu, choose the recovery option.

What do you mean? I didn't think it was that easy to boot a phone? I wanted to put Linux on my phone instead of the current android version or even put them both on there.

I think you need to do some research to get familiar with how android devices actually work. Android devices are not like PC, you can't just install whatever OS you want, android devices are not "generic" like that. Operating systems for android devices have to be built specifically based on the hardware in the device, down to the kernel level, the kernel has to be specific to the device. You need to do some reading about how android stock recovery and custom recovery actually work , you also need to research how android stock firmware and custom operating systems are flashed on android devices.
It is "possible" to remove android and install Linux on an android device, but only certain devices can do it, depending on the security built-in to the bootloader that is installed on the device. There isn't a universal way to install Linux on android.
It is also possible to install Linux on top of android in a sort of emulator/VM then use a VNC to .
There are some apps to install linux on top of android, such as:
1) Linux Deploy
2) Complete Linux installer
3) UserLAnd
I installed and tested UserLAnd last night. Try this and see what you think.
https://github.com/CypherpunkArmory/UserLAnd
View the README.md for instuctions to set it up.
