TWRP 2.8.6.0 attached on 1° post

I installed TWRP 2.8.6.0, linked at first post, but I do not see available the mount function esternal storage (eg. SD)

There because this function is missing in this TWRP version or is missing in the hardware tablet?

Hi. I'm new. I don't speak Inglish very well.

I have a GT-P7510 (16GB) whit Android 4.0.4. Would you recomend me this ROM for my tablet?

My question is the same, what files do I download, to put the Lollipop Rom on my Samsung Galaxy Tab 10.1 GT-P7510

Thanks you all for helping us!!

First Install:

1.Install TWRP 2.8.5.0 or newer

2.Do a Factory Reset

3.Wipe Cache and System

4.Install the ROM

5.Install gapps

6.Reboot into the ROM (The first boot will take longer than Android 4.4.4 and older ROMs. Android Runtime (ART) is slower than Dalvik at optimizing applications the first time.)

Looks like sideload is not working in TWRP 2.8.6.0. It's been a while since I've used sideload so I don't know which is the last one that works.

Unless there was some previous TWRP for this tablet could mount external storage then something changed between then and now that made it not work. Otherwise I have no clue. I don't have any external storage accessory to try.

The Linux driver is similarly closed source and abandoned by NVidia. So it's probably no different than the Android driver.

Yours is the p4. The p4tmo is the p4 from t-mobile. It's just slightly different.

[Galaxy Tab 10.1 Android Development] decatf:
I don't have any criteria for calling it beta or stable. It is only a setting on the forum Edit Project page. The remaining things that are not working are harder to fix. So if anyone considers those necessary for stable status then it will not be stable anytime soon.

One feature that I would consider beta is F2FS. That is still a continuing work in progress by the F2FS developers. As of this moment I've been using the current version of F2FS for 2 months without any problems. I plan to update it as new versions are pushed into the mainline kernel so the stability of that will change over time.

Probably yes. If the previous Kitkat ROMs have worked then this should work too. Instructions on how to install are in the first post.

[Galaxy Tab 10.1 Android Development] Sharky444:
I think one of the reasons why this tablet is so slow is no TRIM support in the (any) kernel. The flash is probably at 20% speed compared to the initial state, especially when writing.
[Galaxy Tab 10.1 Android Development] Sharky444:
Which tool are you using to overclock? I'm using CPU Control Free, but it crashes often. Also it doesn't survive a reboot.
[Galaxy Tab 10.1 Android Development] rtiangha:
I see what he means. The option to mount external storage doesn't appear in the TWRP menu (I assume it should be under Mount?). I don't know if it's supposed to appear when a USB storage device is attached and otherwise hide itself if not, or if the option is always supposed to be there.

HOWEVER!

I have an OTG adapter and was able to test and I *can* mount it manually using the TWRP terminal by typing

mount /dev/block/sda1 /sdcard/SOMEDIR

So it is possible to mount external storage within TWRP and we can at least rule out the problem being a missing driver. Note that this is on my p4tmo device, and I don't know if it's different in terms of built-in drivers and other options compared to how the other device kernels are built.

Hope that at least helps a little, and I'm happy to test things if you need me to since I do have a couple of devices with built in 30 pin Samsung OTG connectors (one a combo cardreader and USB port, another a straight up USB OTG cable). Just let me know.

EDIT: It's also the same sort of problem when running the rom. It doesn't automount when you plug in the storage device but the system still detects it. You can still mount it manually via the command line and if you install Chainfire's Stickmount program, that'll give you the option to mount it or have it automount it in the future.

Hi there. Once again, you can use noFrillsCPU for that. Piece of cake :cool:
[Galaxy Tab 10.1 Android Development] rtiangha:
I'm using noFrills from F-Droid to overclock myself but it's weird. I have pattern lock and if I unlock the tab right away as soon as the lock screen appears on boot up, things are fine and I see the noFrils overclock toast notification. If I wait like 10 seconds and then log in, I don't and no matter what I do in the app to try to overclock the CPU, it doesn't work even though the app says it does. The only way I can get it to work again once I've gotten to that point is to reboot the tab. Not sure if that's a bug in the rom or the app.

Thou the performance was quite promising in latest tests, you should consider it BETA for now. Don't use it to store any data you're not prepared to lose - so BACKUPS are mandatory! If you wanna give it a try anyway, you can convert /cache and /data. Here are some hints for the migration.

[Galaxy Tab 10.1 Android Development] decatf:
Is there even a working method for running Ubuntu on this tablet?

One possible way to boot other OS is using Multirom but I've tried implementing Multirom months ago and couldn't get it to work. I haven't seen any Tegra 2 device that had Multirom working.

I have not done a performance comparison with the current version. I used Androbench if you want to test it yourself.
[Galaxy Tab 10.1 Android Development] DE52:
Back in the days, you could run a reduced version of Ubuntu on this tab via an emulator. I had installed it, but it was obviously slow and didn't have 100% functionality, but it did work. You just needed a bluetooth keyboard and mouse to use it since the touchscreen couldn't be used. Here's the link to a youtuber's article about it + instructions : Tabuntu Edit: it is from ICS days, so it is outdated obviously just like the rest of this tab lol

guys a friend gave me his old GT-P7510 will this work on it? it's wifi only model (this thing stuck on ICS! WOW)

TWRP in Odin which option do I tick in Odin for Recovery?

EDIT: I found out but after flashing recovery it's stuck in black screen any ideas why?
[Galaxy Tab 10.1 Android Development] Prowler665:
First of all your tab is a p4wifi so make sure you are using the right versions of TWRP/ROM.

The md5-hash for twrp2860-20150419-p4wifi.tar.md5 should be d9a70bd44abd3a11db9793218983fa24

If you can still get the tab into download-mode simply try again to flash the recovery in odin. Make sure only "Auto Reboot" and "F. Reset Time" are checked. Check PDA and select twrp2860-20150419-p4wifi.tar.md5...

Hi Ken,

I am not sure if you already found an answer to your question.

I had the same problem.

Turns out that the option you're looking for is only available in the p4wifi ROM, not in the p4.

I just flashed the p4wifi as I do not use the SIM card option.

[Galaxy Tab 10.1 Android Development] Prowler665:
SetCPU and NoFrills are known to work, but most others might work just as well. Just don't use the DeviceControl-app since it has a, let's say, not so bright history on this tab.

If you are into undervolting, or setting voltages at all, SetCPU is the only way to go since afaik only SetCPU is supported for this.

Nice ROM, thanks to the dev

Quick question:

Are you able to connect an usbdrive?

When I connect an usbdrive, it is detected but it is empty.
[Galaxy Tab 10.1 Android Development] rtiangha:
You need to install something like Stickmount from the Play Store for the drive to mount automatically; the rom doesn't seem to do it itself. If you're good with the command line, you can also mount it manually through a terminal.
[Galaxy Tab 10.1 Android Development] Reggy Noble:
Thanks but...

Stickmount does not make any difference.

As mentioned, the usbdrive is mounted (detected) but there is no content (it's empty)

With other ROMs I can use it no problem.
[Galaxy Tab 10.1 Android Development] rtiangha:
Mounted and detected are two different things. Mounted means the contents of the drive are linked to a directory (which doesn't seem to be the case for you) while detected means the rom senses it has a drive attached (which does seem to be the case).

The only thing that I can think of (other than going into Stickmount to verify that it mounted the drive) is missing drivers. It works on mine with a drive formatted in fat32 but what is yours formatted in? Exfat? NTFS? HFS+? I haven't tried those myself but if yours is different, I could try to replicate the result on mine.
[Galaxy Tab 10.1 Android Development] juniper1982:

[Galaxy Tab 10.1 Android Development] rtiangha:
Not sure how you can root your Tab if you can't connect to your PC, but assuming you can obtain root access, you could flash the Odin version of TWRP through Mobile Odin then the rom through TWRP.

Hi,

First of all, thanks, it's seams a very good work and amazing to see my "old" device with new Android.

I would like to know if there is an app to set the GPU frequency, like for the CPU. I see that the kernel has the settings to reach the 1.6Ghz but by default the device is set to reach only the "standard" 1Ghz Frequency. I used antutu to set the max CPU frequency at 1.2Ghz, but I'm bored about youtube experience, I don't know why from one month ( more or less ) it's impossible to watch a video from youtube official APP unless set to 360p!!!! . Thanks in advance for support!

I use Kernel Adiutor and have my max set at 1.5ghz.......I can watch youtube at 720p with less then %1 stutter.....Give it a shot...480p runs like butter...I get solid 1800 score on AnTuTu...I know thats not much, but is way better then stock:good:

At the risk of sounding boring, this happens to me as well. Previous versions of this ROM have been stable with G+. Also have a problem with BBC iPlayer, live streaming. After a few seconds, there is a click and the screen goes black. Sound continues.
[Galaxy Tab 10.1 Android Development] DE52:
I have no idea what the problem might be as I don't use G+ on my tab lol, but from what I can see, you and 2 other people have the issue, so must be either a common mistake (as in the Gapps used for example) or something else. Maybe one of you could get a logcat of when the crash occurs? (unless the dev tries on his tab and gets the same issue)
[Galaxy Tab 10.1 Android Development] timgoodwin:
This does not seem to be an issue with Gapps - have flashed the version specified and the problem persists. G+ will sometimes work for several minutes, but when it crashes it then crashes quickly again.

lollipop tuning guide for older, slower platforms

I ran across this writeup while trying to bring some snap back to my nexus 7 (2012) running stock 5.1.1:

On docs.google.com/document/d/ -- file:

1--5lhynOduiDDB61Zh1hECY6tYzJA852wGFbQa2pK1E/pub

Some items are nexus 7 specific but many settings apply to our tab 10.1 such as google's many background defaults. I'd be curious about other decatf users experience after applying these settings; my perception is all positive (knock wood), even if marginal. Every bit helps on this old slab.

Also, I still suspect enabling fstrim in the kernel would help many with full-ish flash. The BrickBug issue is largely understood at this point and at least my tab has an eMMC controller that is not brick bate (Type SEM16G, FwRev 0x90).

Check your own and see (use eMMC Brickbug Check from the play store).

USB not working.

I don't know if i'm posting this in the right thread. Does this rom have like a bugg rapport thread or something?

I have successfully installed this rom onto my p4WiFi, it works great but as the title says, the usb won't work with my laptop.

I use CWM and have had CM 10.1 installed previous.

After flashing the zip for the rom and the gapps my computer (Windows 7, 64-bit) doesn't recognize the device. I have the usb drivers for this device installed since i rooted it but all that happens is that I can hear the usual "connected device beep", first i get a "USB device not recognized" (Translation...? it's from swedish...) but at the second try windows tries to install drivers for "MTP" and "p4WiFi", but the drivers won't install correctly. "p4WiFi" fails and after some seconds the "MTP" driver changes name to "p4WiFI" as well. This one installs successfully and for a second the dialog where i can choose to browse files, etc appears, but just to vanish the next second. And then it just appears as an unidentified usb device in the device manager.

The device does not appear in the adb list either ("adb devices" command from the platform tools in the sdk... [ am i even doing this right... idk...] usb debugging is ofc on :silly: )

I'm not totally new to rooting and custom roms, and definitely not to Android overall, but i'm still learning SO PLZ don't call me dumb or anything...

I don't know if this made any sense, but does anyone else have this problem? Someone knows how to fix it?
