Error file_contexts.bin

Hello,

After flashing my gtp 7500 3g with wcm, when installing the nougat version I have an error message that says this:

"No file_contextsTarget: samsung/GT-P7500/GT-7500:4.0.4/IMM76D/XXLQ8:user/release-keys "

Do you know how to fix the problem.

open_gapps-arm-7.1-pico-20170119.zip

P7500-open_gapps-arm-7.1-pico-20170119.zip​

These 2 links in the original post lead to the same file. Is one of them meant to go to the 7510 version?
[Galaxy Tab 10.1 Android Development] viktak:
These links do point to the same file, but that should not bother you: there are no separate versions for the 7500 and 7510.

I don't know why the duplicate links though.

I got an error flashing P7500-open_gapps-arm-7.1-pico-20170119.zip

from https://github.com/opengapps/arm/releases/tag/20170119

Are they exactly the same thing as well? Anyway seems to all be working - except in Google Maps (the latest non-NEON version) the map picture sometimes goes blank, even though the navigation directions work.

Yes, that's the one to flash. I used the same as well, and it works without any FCs.

Anoying play services restart

First of all... thanks ! It's very useful and environment friendly can still using this 10.1 tab.

Then, I have a problem: I follow the steps and configured Play Store to not auto-update anything.

But play services updated anyway and then continuously appear an advice: "restart the app" and is impossible to use it.

Any idea ?

Thanks in advance
[Galaxy Tab 10.1 Android Development] viktak:
I have this one installed: http://www.apkmirror.com/apk/google...ogle-play-services-10-2-98-release/#downloads (search for "10.2.98 (430-146496160)") on the page.

It is not auto updating and works flawlessly.

Earlier in the comments this version was recommended - you can try it too: http://www.apkmirror.com/apk/google...s-10-5-42-430-149175906-android-apk-download/

I just want to say a BIG thank you to decatf and everyone else's help for putting new life into our old tabs to work with Nougat. I'm very sad to see this project coming to an end and I really hope someone makes Android O for it in the future that's if it's possible, now that everything has issues with older phones/tabs. I have followed the advice and everything works perfectly now (No more force closes). I only have a issue with candy crush saga and I can not play it at all. Not sure why it keeps flickering when it starts but other than that I'm very happy with this ROM. :D

Ideally, you have downloaded it to your device. If not, transfer it to it, then start a file manager, like this, navigate to the APK file, then launch it (tap it).

Would you mind bundle Adaway and phh superuser inside your ROM?

I suppose their EULAs allow them to be distributed as far you (or any other developer) changes them.

It would be easier and much more convenient ;)

SwiftKey

Sorry, no success. I have the same problem. Using Swiftkey as soft keyboard there are no keys but only the word suggestions. Has somebody any solution?
[Galaxy Tab 10.1 Android Development] UncleDick:
Installed Fleksy Keyboard. This keyboard seems to work fine. Can switch between AOSP and Fleksy (and back) over and over. Unfortunately, Fleksy does not appeal to me, as I use SwiftKey on my phone.

Conclusion: the issue may lie with SwiftKey rather than with the ROM, although there have been stories about SwiftKey working with Nougat emoji, which would seem to imply that SwiftKey is known to work on Nougat. I may try a couple of other keyboards. The more that work correctly, the more likely it is that SwiftKey has a problem.

[Galaxy Tab 10.1 Android Development] UncleDick:
Installed three more keyboards. They all work correctly. Switch among them over and over.

SwiftKey is the only keyboard so far that "displays no keyboard" and is thus unusable. (sigh)

---------- Post added at 10:52 PM ---------- Previous post was at 10:08 PM ----------

I just ran some quick "Ookla SpeedTest" using my Netgear router attached to Time-Warner cable Internet. There is nothing "exact" about Ookla reports.

. ..................... Down - Up

HP Desktop (hard wired) 70.00 5.88

Windows 10 Laptop @ 2.4 42.01 5.97

KitKat Phone @ 2.4..... 45.94 5.92

KitKat Phone @ 5G...... 70.51 5.90

p4wifi Nougat @ 2.4.... 29.64 6.33

p4wifi Nougat @ 2.4.... 28.91 6.04

p4wifi Nougat @ 5G..... 24.51 6.42

p4wifi Nougat @ 5G..... 21.90 6.27

HP Desktop (hard wired) 70.86 5.95

Upload speed on my Time-Warner service is capped at about 6MB/Sec, so it appears all devices are able to drive the network link at full speed.

Was surprised that my ancient Droid Mini running KitKat was able to drive the 5G connection as fast as the hardwired desktop computer. Just over 40MB/Sec seems to be the throughput limit on the 2.4GHz router link. Nougat on the p4wifi appears definitely slower than my old laptop or Droid Mini. (The last test was to verify that my network had not changed dramatically between the start of the test and the end.)

Conclusion: Yes, the p4wifi running Nougat appears to be considerably slower on the network than the two other wifi devices at my disposal. This is not much of a surprise since it is "older" than they are. What was more of a surprise was that the p4wifi performs worse on the 5G network than on the 2.4. When I do a WiFi scan, my 2.4 band is littered with nearby routers and my own house has over 20 devices connected at 2.4. My 5G band has no nearby routers and I have few devices connected to the router. Maybe the early 5G network code wasn't fully developed when old tablet came out?

However, I'm not sure it's fair to call the tablet's network speed "poor". It will drive my router at more than 20MB/Sec, which is faster than most of us could have hoped for only a couple of years ago (and many people do not have yet.)

Dear all,

this is my first post here - total newbie. So today I got the idea to finally update my 4 year old GT-P7500 and read all the ncessary steps here in the forum.

Here the steps I preformed:

1. Installed thru ODIN - twrp3020-20160911-p4.tar.md5

Worked perfectly - Wipe cache, dalvik cache, system, data

2 Installed ROM - aosp-7.0-p4-20160929

After Installation I did a reboot into TWRP

3. Installed Kernel - p4_kernel-aosp-7.0-20161002

After Installation I did a reboot into TWRP

4. Installed gapps - open_gapps-arm-7.0-pico-20161008

Reboot started my Android

After 5-8 min showing in written form "android" the tab started. When I wanted to insert my account data "...services has stopped"

Alright went to menu started google play again "services has stopped", updated the apk to version 7.0.18 still same error.

Altogether found the following erros:

- Google play 7.0.18 immediately after start - "...services has stopped"

- Google Chrome 53.0.2785.124-278512402 immediately after start - "...services has stopped"

- Internal Internet Browser is working but if I want to download a file "...services has stopped"

I also Wipe cache, dalvik cache, system, data and did the installation of gapps again - still the same errors.

Any ideas what could be wrong, also I delted the cache of the play store - did not help? I created for help the "logcat" (delted the entries before 10-09 01:58:20.892) and it can be downloaded here in the attachmend files.

Question - if this Rom is still making trouble, which really stable rom (please with a link) can you recommend me for the time until I try it again with this rom?

- [ROM][Unofficial][AOSP] Android 6.0.1 Marshmallow

- [ROM][Unofficial][AOSP] Android 5.1.1 Lollipop

- ... ??

Thank you very much for your help and feedback !!!
[Galaxy Tab 10.1 Android Development] UncleDick:
More senior people will have better technical answers for you. Until they have time to respond, it might be useful to point out a few things:

Any time you wipe system, you need to flash the ROM again. i.e. you cannot wipe system and then flash only GApps.

It is perfectly OK to flash several zip files together. For example, I usually flash the ROM, GApps, and supersu at one time. (Just keep 'adding' them to the flash.)

Many of the programs provided by Google have begun using the "NEON" instruction set, which the ARM chip in our tablet does not support. Chrome, for example, will not work after version 49. (Get it from the APK mirror web site.) The Google search application which comes with any GApps larger than 'pico' also uses NEON and doesn't work. Also the YouTube app.

About 1,000 people have downloaded the 7.0 ROM. Most of us are using it successfully. So, "which is more stable" (for me) is "all of them are the same. They all work." I used 5.1.1 for months, 6.0.1 for months, and now 7.0 for several weeks. I don't mean to make light of the frustration. (I once wiped "internal storage", which was NOT a good idea!) There is no harm in downloading and flashing Marshmallow. A working tablet on Marshmallow is better than a brick on Nougat. If Marshmallow installs for you, then you're "back in business."

p.s. Being only slightly ahead of you on the learning curve, I often think I know more than I do. Answering questions is a way to prompt people who know more to point out things that I misunderstand.

Good Luck!

Thank you for your advise, but unfortunately it doesn't work for me. If I flash ROM and GAPPS this way tablet doesn't boot at all (shows only "Galaxy Tab 10.1").

Somebody wrote about battery issue - after charge with stock adapter battery level doesn't get full. In my case, after reboot battery level shows properly.
[Galaxy Tab 10.1 Android Development] viktak:
If you haven't modified the partitions then you don't need the pit file. The easiest way is to go back to stock (with Odin), then start all over.

[Galaxy Tab 10.1 Android Development] Andargor:
Thank you for this! I followed the instructions, and installed the recommended APK versions.

However, after a certain while I'm seeing a lot of CPU activity, up to the point where the tablet is no longer responsive. Rebooting makes it snappy for a while, and then it degrades again. I basically use it to view PDFs and browse with Chrome (latest stable as mentioned here, 49)

7.1.1 seems to have removed the "Show CPU activity" option in the developer tools, so I'm unsure what is causing it. Any ideas?
[Galaxy Tab 10.1 Android Development] viktak:
Try this in twrp: advanced wipe-> system, cache, dalvik cache, data

If it doesn't help, I'd suggest starting from the beginning. These are the steps I did, and I don't experience the performance degradation you mention.
[Galaxy Tab 10.1 Android Development] Andargor:
Thanks, I'd actually followed your steps when installing, except for superuser. I'll do it again, except with superuser this time, and see whether I can see what's eating the CPU if it happens again.
[Galaxy Tab 10.1 Android Development] Tankmanbrad:
Great ROM! Smooth.

Titanium Backup reports only 63MB clearance with way over 500MB as overhead System ROM, and TWRP 3.0.x shows that near a same amount used as system image besides system ROM 500+?

Is there a way to reclaim that? I think 5.1.1 AOSP showed 109MB clearance, so its running smaller. Or does it make a diff, or umder what circumstances would it? Not 3D modelling Broadcast HD video with it or anything...

Desktop base is a Mac with Android File Transfer app, not sure if it would show root level if I factory wiped and unrooted, if that seems to be the only way. Otherwise nice to just drag and drop into the P7510 with installs... I jinked into root level via android file manager app, initing the ROM+Recovery loads way back before this app, i think.
