official builds are builded on lineage servers and they have ota support.

andis unofficial builds are builded by him self. he use unofficial builds for testing new stuff. unofficial have no ota support.

the prefered filesystem is ext4.

you can overclock lineage if you build your own OC kernel. all sources are free to use. no OC support from android-andi

[Galaxy Tab 2 Q&A, Help & Troubleshooting] Android-Andi:
I hope I am right here with my question:

How does it come people use stuff from other devs as base and don't ask for permissions?

I mean, everything is opensource and can be compiled without trouble...

Best i have seen here recently: remove one app, add 2 other apps, sell as own work...

Don't get me wrong, I love open source and that's why I pushed everything we did on tab2 to omni, cm/lineage and Slim official.

Another note:

IMO there's no need to use android kitchen and such stuff to bring N on Tab2. And if you are going to do so: test your stuff before it goes public to user...

It is not a boot loop, it looks like dead battery to me.

Hello everyone, I haven't used the device in forever and got into maintaining roms, I was curious as to what dependencies should be added to my roomservice.xml to build the rom so it doesn't end up in a bootloop like my RR 5.8.2 build. Any suggestions? and is there any specifically new files i need to flash (like a new bootloader for instance). i am trying to narrow down to get a working nougat build going. thanks. ^^
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Android-Andi:
[MENTION=5917244]smart-t78[/MENTION] compiles RR already.

About N in general:

There is different reasons why there are no public N builds beside UA yet. Some examples: there is no need for 20 different Roms with a bunch of big bugs. We concentrate on UA to get a stable base.

I am working on fixing major bugs before all source goes public.

At the moment slim7 and omni7 both end in a softrebootloop once you connect to wifi. Same happens on Lineage 14.1 once gapps are flashed. I spend almost 1 week fixing it without luck and i am going to drop it if i dont find the reason for it soon. Logs dont give enough information... Same on 3.0 and 3.4 kernel...

Be patient and if no stupid ETAs start there is a chance seeing one or the other N Rom which source you can use.

Found this old tab at my parents house its a p5100 currently in the version 4.2.2. I've been reading the forums but i only find threads on how to root the tab in specific older versions like 4..0.4. Does the same method apply to the version 4.2.2 or do i need to do something different?

It would be great if someone could point me in the right direction thanks
[Galaxy Tab 2 Q&A, Help & Troubleshooting] smart-t78:
android N for our tab works only with 3.4 kernel at the moment. you are building with the 3.0 kernel source. thats the cause why your builds are not bootable.

Which one should i use?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Hawaiihemd:
It has been a long time since the stock rom days for me but I would do it as follows:

1) install common twrp by Android-Andy via Odin http://andi34.github.io/recoveries_tab2.html

Make sure auto-reboot option in Odin is DISabled!

2) Reboot directly to recovery via holding volumedown + power button for about 7 seconds

3) Backup efs, system and data partitions to a microSD card

4) flash recovery flashable zip of SuperSU from http://www.supersu.com/download

5) have fun

Oh one more thing: I would suggest you update to a more recent android version for productive use. An android version that old has so many security related bugs it's not even funny.

LineageOS 13 by Android-Andy as well is a very good replacement imho.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] twilighttony:
That's understandable. I hope so though because i would to help in any way I can. I am trying to get really into development rather than just maintaining and helping would teach me alot as well as maybe even keeping this project alive for even longer time. Can you pm me if that is alright?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] noobexplorer:
Thanks a lot man, worked like a charm :good:.

Could you help me with that Custom roms business, can you recommend one or is it against the rules? By the way can this tablet Run OC kernels or is it a bit to much to handle?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Hawaiihemd:
Sure, in any way I can...

As this is a general q&a section rom suggestions are just fine imho.

I personally have only used CM and now LineageOS builds by Android-Andy. I for one can say that I have found them to be among the best custom roms I have ever tested on various devices. Andy just doesn't do public beta testing ;) Rock solid stuff... Serves me well.

Your mileage may vary though. Just try out some roms to see what's best to fit your needs. Just always have a good backup and you'll never lose.

As for OC... I have no idea if there is an up to date kernel that has it. But there is a new thread out there explaining how to roll your own kernel and add features. If I just had the time...

I'm new to tab 2 10.1 P5100wifi. I got it from a relative and rooted it and installed twrp. Every custom rom I install has no audio on any streaming apps.

[Galaxy Tab 2 Q&A, Help & Troubleshooting] smart-t78:
sounds that you installed the wrong rom-variant.

p5100 = espresso3g

p5110 or p5113 = espressowifi
[Galaxy Tab 2 Q&A, Help & Troubleshooting] cityneversleepz:
yes but check this out. when I look at about phone on the stock rom, it says it's Model Number GT-P5100. Okay, so I install espresso3g roms and I get TWRP message that my device is espressowifi. And the 3g rom will not install.

[Galaxy Tab 2 Q&A, Help & Troubleshooting] tetakpatak:
P5100 is a 3G tablet. If your tablet has no SIM card, you must have flashed with Odin P5100 recovery.

If so, you can revert it back if you flash a P5110/P5113 recovery (it is the same file) as tar file with Odin 1.85 or 3.04 or 3.07

I have my grandma's old Galaxy Tab 2 10.1 so I can replace the battery and install a version of Android that isn't packed full of bloatware. I can get to those later; first, I have to solve a bigger issue. The tablet isn't detected by any computer I have plugged it into. By "not detected", I mean it doesn't show up in Windows Device Manager -- and I can't find it when I use my Linux machine either. I have also tried a few different 30-pin cables, and it doesn't work on any of them. At this point, I think the USB port on the device might be dead, but I doubt it because the device can still charge. Would someone please help me figure this out?

Did you do a full wipe? I would reboot to twrp, make a data backup (to an external sd card) and wipe system, data and internal storage. Then install whatever custom rom you want and see if it boots. Remember to be patient on first boot.

Hi folks.

My head is swimming at this point trying to sort through to assess which procedures would likely help me to achieve a good customization with my tablet. I'm willing to continue reading of course, but am hoping for some direction to help me sift al through a bit of it.

I have a

Build- JDQ39.P5113UEUCMK3

Since this tablet is an older one, my first question is whether it is reasonable to think that I can use any of the files listed on this site pertaining to my tablet model to root and flash my tablet to rid it of most bloatware and end up with a tablet that streams youtube LIVE video without crashing ? I try using "Desktop mode" since I get errors when using the youtube app (Ive had no success with various browsers along with side-loading adobe Flash. I get crashes and/or "Your browser does not support HTML5 format video)

I generally use my tablet for:

1. Streaming live video on youtube (in desktop mode so that I can avoid the automatic commercials that interrupt when using YT's app, and cue past any others).

2. To search and surf pages for info.

3. To stream/view live video,and play embedded video on C-span, for example.

No chats , email, shopping, etc.

So, I'm hoping that someone can point me in the direction of a good ROOT and a tried and well functioning zippy ROM for this tablet and my habits.

I've searched specific to my model and gleaned bits of info but am in information overload and unsure of how to sift through to find what is useful to my objective.

---------- Post added 16th August 2017 at 12:03 AM ---------- Previous post was 15th August 2017 at 11:26 PM ----------

I think, Ill probably choose RR as an OS. Do I understand correctly that I do not need to take other steps before following the instructions at the link you provided? ie; download samsung drivers for the Tab and use my PC in conjunction (As I have read in other posts) ? NOR unlock my bootloader? That the procedure is as simple as what is posted there? One more clarification, once that is done my android version is complete because this replaces it, no need to upgrade to Marshmallow, etc ; ?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] guest4711:
You need to have a custom recovery (TWRP) installed. If you don't like to use your PC for downloading and installing, you should put the files on sdcard and install from there. If your tab is rooted, you may use TWRP-app to install the custom recovery. Otherwise you should use USB for installing the recovery (see the various threads about installing a custom recovery on tab2).

If you own the WiFi-only version of the tab, you

should not need to update the stockrom first...

Good luck and have fun!
[Galaxy Tab 2 Q&A, Help & Troubleshooting] lenolver:
Thank you.

I do own the wi-fi only.

I am not opposed to using the PC in fact, would prefer to do my downloads there. I was just asking that because I'm trying to solidify what is prerequisite to do and what I don't need to do., as I'm in information overload from reading but fear not having all steps necessary in their proper order. I'll do that reading ;)
[Galaxy Tab 2 Q&A, Help & Troubleshooting] lenolver:
So, I've done a ton of reading and think that I'm getting a better general sense of what I need to do. May I get some "Tech check " on what I gather so far? I know, I'm not ready to go for sure and what I've listed below I'm still refining in my mind what order they should be used in the process but, I'll appreciate any feedback to help me get perspective and re-target what I need to search and read further., where I'm over-thinking and under-thinking.

I gather , that to achieve ResurrectionRemix on my tablet (from it's unrooted state) using my PC that: I do not need to root my device, I do need ODIN to flash with, a custom recovery (TWRP), samsung usb drivers, RR ROM, and gapps.

1. Make sure that I have Samsung Tab 2 usb drivers installed on my PC

2. Download ODIN to PC

3.Download TWRP (I'm still not sure which file is best in my instance. Just when I think I've found the right one, I read something in a post that indicates it isn't the right one or I find a newer one and become unsure if I should use the latest, or a specific ".tar .img or .zip. )

4.Download the Resurrection Remix ROM specific to my device to my PC (Seems to be this one? https://www.androidfilehost.com/?fid=385035244224398612 )

5. Download gapps ? *I'm not quite grasping yet, which gapps file I need and when in the process to install this.

6. Transfer both TWRP and RR by usb to my SD card in my tablet ? Or , will ODIN access them fine from my PC desktop to flash them to the tablet ?
[Galaxy Tab 2 Q&A, Help & Troubleshooting] john99ap:
First, you will use odin to flash the twrp recovery. Then, you will boot your tab in twrp and from there you will install the rom and gapps. You need to transfer to your sd the RR rom and the gapps zip.

Twrp link: https://twrp.me/devices/samsunggalaxytab2wifiunified.html , download the .tar file.

RR rom link: https://www.androidfilehost.com/?fid=745425885120747564 , this is currently the latest build. There might be new in the future, check the dates.

For gapps, download opengapps. The difference between the various versions is the apps they contain (eg pico contains the absolute basics like play store, nano some more than that etc). I suggest to install pico and if you need some extra app just get it from play store.

To install both the rom and the gapps just boot into twrp and select Install --> find the zip you want to install --> swipe the bar to the right.
[Galaxy Tab 2 Q&A, Help & Troubleshooting] Hawaiihemd:
Just to make a few details clear (again)

1. The drivers are all bundled up, i.e. not device specific here: http://developer.samsung.com/galaxy/others/android-usb-driver-for-windows

6. You need the .img.tar file of TWRP and ODIN on your PC(!) -> start ODIN (I recommend v3.11.1 here: https://bin.samsung-firmware.org/bin/odin-3-11-1.zip) put the img.tar file in "AP" in ODIN.

This is correct. BUT since you (lenolver) are unrooted you have to REMOVE the "auto-reboot" checkmark in odin options and then - after the flash of twrp - reboot to recovery (TWRP) manually via holding Power+VolDown for a few seconds.

If you do not uncheck that "auto-reboot" box, an thus allow the unrooted system (stock samsung system) to boot, it will overwrite the new twrp recovery you flashed 2 seconds before...

This is the point where I believe many confusion comes from. If you root first, any recovery you flash will not be overwritten. That is - I think - why many tutorials/tips say you must root stock first before installing a custom rom, which is simply not true.
