Is anyone have a unusual battery drain even when is sitting there. And my tablet is getting so hot almost in every app. is only me ? Or is normal I'm using the WiFi version original tab.
[Shield Tablet General] Anonym323:
Same here... Battery drains very fast, no matter if I use it or the screen is locked.

Also got the problem with heat. Didn't had such problems on Kitkat.
[Shield Tablet General] gqukyo:
Solid Explorer works fine for me. I just had to give it access like all other MM apps. You can try File Explorer by NextApp.

Ampere working for anyone? I tried the old measurement method and that didn't work either. Always at 0 mA when charging.
[Shield Tablet General] GuyInDogSuit:
Same here, ridiculously fast battery drain. I'm going back to Lollipop.
[Shield Tablet General] GuyInDogSuit:
OK, this is just fantastic. After spending a few hours trying to figure this out, I'm about to give up. I went back to Lollipop, but now my SD card isn't working right. I was never able to copy anything to it on Marshmallow, so I had no issue with formatting it. However, it now says there's only 16 MB on it. I took it out and formatted it on my PC as FAT32, and it went from 16MB back to 32 GB, but then the tablet wouldn't mount it. What the hell is this and how do I fix it?
[Shield Tablet General] kimern:
Put the SD card in your PC and open command promt (cmd).

Run the command "Diskpart" and wait for it to start.

Run "List disks".

That should give you a list of all disks connected to your PC, including USB drives, SD cards etc.

Find your SD card in that list, and run "select disk your SD card". For example "Select disk 1".

Now, make damn sure you selected the SD card. The next command WILL wipe whatever you selected in the last step. It will not warn you. And i take no responsibility for anything that might happen to your system.

Run the command "clean all", making sure you have the SD card as the selected disk.

Wait for it to complete. It will take about an hour per 320 GB to finish running. Approximately 10 min for 32GBs.

Once it's done, type exit and press enter to close diskpart.

Now open Disk Management.

You should see your SD card as a Unallocated disk.

Right click it -> New simple volume.

Next -> Next -> Next -> Give your SD card a name and leave rest to the default.

Next -> Finish.

Now insert your SD card into the Shield and give it another go. Let me know if that works out for you :)
[Shield Tablet General] linuxgod05:
hi I have a quick question how do I go back to 3.1.1 ? because I am having trouble going back the system image for the stock will not flash I be-leave it has to do with the blob.img that is in it. is there another blob I need to flash to go back to normal?
[Shield Tablet General] linuxgod05:
found out how to fix it sorry please take out this post
[Shield Tablet General] ssj3hulk:
After updating my old LTE tablet, will future K1 OTA updates install? Or I have to go through this install process each time I want to install a new update?
[Shield Tablet General] sockusminimus:
We know that /system/bin/logd is causing the drain. I just made it non-executable. So far the tablet it running fine after a reboot. Not a great solution but it may work as a temporarily until an update is released. Note that this will disable logging on the system entirely. I'm going to test it over the next few days to see if anything breaks and then I will report back here with my findings.
[Shield Tablet General] sockusminimus:
So my fix does appear to be working. I opened a root terminal, remounted /system as rw, and then removed execute permissions from logd. So basically:

mount -o remount,rw /system
chmod a-x /system/bin/logd

Then I rebooted and wiped my cache partition. So far the battery drain hasn't returned.

NOTE THAT THIS WILL BREAK LOGGING!!!
[Shield Tablet General] DrPrinz:
PC shows the I an unknown device but I know it's K1 but he finds no update as I do that ..

Fastboot says waiting on device
[Shield Tablet General] GuyInDogSuit:
Thanks! That did the trick!
[Shield Tablet General] kimern:
Np! Just be aware that this should not be done too often on flash memory (SD cards, USB drives, SSD's etc.).
[Shield Tablet General] IKOB3AST:
So the ROM definitely has a settling period.... as for the battery drain issue that happens at least on the K1. Also, the Bliss M ROM also has a draining issue. But if you turn off the tablet when you're setting it down.. you'll experience the expected battery life. Its only when you go to bed or leave it sit for hours that the unusual battery drain is experienced.

Let the Tablet sit and mount the sd card as external storage, not expandable storage.
[Shield Tablet General] IKOB3AST:
Has anyone else tried this? I'll add it to the guide...?
[Shield Tablet General] sockusminimus:
Still working for me. In fact, this is the best battery life that I've had on any ROM now.
[Shield Tablet General] afilbit:
This works with Shield Tablet K1 right?
[Shield Tablet General] sockusminimus:
Correct. Shield Tablet K1 and original are both supported with this fix.
[Shield Tablet General] IKOB3AST:
This must be an issue with your install. I'd do a full wipe. All of the standard data storage features and OTA work (wouldn't use OTA).

Good luck!
[Shield Tablet General] IKOB3AST:
Did this to my Shield last night... Went to bed at 84% and woke up at 79%. So definitely an exponentially greater improvement on battery life. Would recommend this fix and added it to the guide.
[Shield Tablet General] drewski_1:
i don't seem to have /system/bin/logd? i just have:

/system/bin/log

/system/bin/logcat

/system/bin/logname

/system/bin/logwrapper

:confused:
[Shield Tablet General] tekilebrio:
I can't mount /system folder has rw. I'm using es file explorer and terminal without luck.
[Shield Tablet General] sockusminimus:
In terminal are you sure that you are first typing "su" so that you can run the mount command as root?

---------- Post added at 01:11 PM ---------- Previous post was at 01:09 PM ----------

Okay now that is really weird. Perhaps try running top and looking at the top of the list. That will tell you the executables using the most CPU time and where the binary resides on your filesystem. There might be Android applications that can also show you a process list. You can run that instead of top. I'm just most familiar with the command line.
[Shield Tablet General] tekilebrio:
Yes I do. I follow the instructions Bo appears error or something. Assuming everything is OK but the folder never mount rw. Is weird I know but I don't know why.
[Shield Tablet General] codemansGT:
I seem to be having problems making /system rw like some others. I can see logd in solid explorer can I modify the file to make it non-executable in solid explorer instead?
[Shield Tablet General] sockusminimus:
And your tablet is rooted and you set it to allow applications to request root access?
[Shield Tablet General] codemansGT:
of course
[Shield Tablet General] tekilebrio:
Ok I find the problem. In the recovery I have to choice allow system modify in order to get a folder system rw. Is all I do and now can modify the logd file.
[Shield Tablet General] codemansGT:
can you describe how you did this in recovery and when you did it, did you boot back into system and use a terminal emulator to use the chmod a-x on logd?
[Shield Tablet General] JamesPatageule:
Hi guys,

I justed tried that and following this guide by letter.

I finally got the marshmallow update !

But now, i lost my recovery !

I tried with VOL DOWN + POWER, and nothings appends ...

So i use the "adb reboot recovery" way, and the tablet reboot, but NVIDIA logo and then, android ...

I tried to flash again TWRP, but it's the same ...

Anyone can help me plz ?
[Shield Tablet General] teachmeluv:
What version of TRWP you have flashed? The experimental one from this guide?
[Shield Tablet General] drewski_1:
i can see logd in ES File Explorer, but not Root Explorer ?

After i changed the permissions i could see it in Root Explorer . . . Until I rebooted and then it was not visible in Root Explorer again.

But it did help tremendously with battery life!! ?

[Shield Tablet General] codemansGT:
What did you change the permissions to?
[Shield Tablet General] drewski_1:
Remove execute permissions per this post

[Shield Tablet General] tekilebrio:
1.. go to recovery mode.

2.. go to mount option

3.. and uncheck mount system partition read-only

Then you can follow the guide to fix the drain battery.

Note this is only if you have problems mounting the system folder as rw.
[Shield Tablet General] Hiznbrg:
Followed the given instructions, tablet booted fine, deleted tergraota, everything runs well except TWRP says no recovery image found and won't boot into recovery mode through TWRP or with power + volume down method. So where do I find the recovery image and how do I install it?
[Shield Tablet General] drewski_1:
there is the Experimental TWRP linked in the OP along with flashing instructions (step 11) . . . though it sounds like you're already in TWRP? :confused:
[Shield Tablet General] Hiznbrg:
Any problems with reflashing TWRP at this point?
[Shield Tablet General] drewski_1:
you should be able to re-flash with no issue.
[Shield Tablet General] Murph22:
So i just got this tablet and after hours and hours of research i think i want to go this route.. one question can i use Nvidia Grid? or Moonlight? if i do this method?
[Shield Tablet General] Djabolic:
Both will work.
[Shield Tablet General] KCKitsune:
Does anyone know if there is a better TWRP than the one in the OP? I like TWRP, but this one is so... slow. It is giving me problems with doing things like wiping the cache memory.
[Shield Tablet General] Bergdoktor:
no LTE?

Please put a warning in the OP that LTE isn't working with this rom. I almost already went through with the update before I read about lack of LTE support somewhere in this thread.
[Shield Tablet General] Trafalgar Square:
Problem

Hello,

I flashed all IMG's and my NVIDIA Shield Tablet is booting into system. I tried to boot into recovery but it's not working. My Shield stucks at the NVIDIA Logo.

Please help me. Thanks!
[Shield Tablet General] KCKitsune:
Did you keep the experimental TWRP from the first post?

I know it the experimental one is a pain in the butt, but that's the only you can use. If you flash another one, then Recovery won't boot.
[Shield Tablet General] Trafalgar Square:
Hi,

thanks :)

I flashed the experimental now again. I had to wait 30 seconds and then the Shield booted into recovery. Using Bliss 6.0.1 now.
[Shield Tablet General] KCKitsune:
You're welcome.

I'm just waiting for a better version of TWRP. The current one works... to a point. I just wish it wasn't lagging so badly. I almost accidentally did a factory reset, and only due to fast fingers was I able to avert catastrophe.
[Shield Tablet General] skooter32:
Will this method work on nvidia k1 and will the battery drain fix fix mm on the k1?m

Thanks in advance
[Shield Tablet General] drewski_1:
No need for this method. This is based on the Official for K1 [emoji6]

The battery fix should work on the K1 too, but as stated you will lose logging.

[Shield Tablet General] skooter32:
Logging?
[Shield Tablet General] drewski_1:
if you're asking, you probably won't miss it ;)

until you report a bug and the dev asks for logs :eek:
[Shield Tablet General] skooter32:
Ha thought it was that but normally by the time a get round to report a bug someone already has cheers bro
[Shield Tablet General] MarkyparkyMeh:
It worked! Many thanks.

Problem is, even after installing the Stylus launcher app it doesn't show up when I remove the stylus from the tablet. I also can't seem to enable the two extra buttons that are supposed to show up when the stylus is removed (the one that allows a lasso screen capture and the other that makes the screen stylus-only.) Checking the box for this does nothing.
[Shield Tablet General] fards:
Make sure the settings are correct. You can't add Apps to the launcher, but it opens (it isn't designed for marshmallow. )

The lasso is a function of framework, you are using a rom designed for a tablet that didn't have that functionality. It won't work
[Shield Tablet General] Murph22:
WOW!!!! Thank you! This is amazing.
[Shield Tablet General] s4shield:

[Shield Tablet General] linuxct:
I'm shocked - I did all of this tutorial during saturday on my Testing ("flamable") Original Shield Tablet, and all went fine (thanks OP & all crowd involved), but, now, I'm receiving Shield K1 OTA 1.1, so this proves we can even receive the K1 OTAs now? Shall I try to do it or will it just break everything up? Hehehe.
[Shield Tablet General] KCKitsune:
Do a nandroid back up of you're current setup, transfer that backup to a USB drive (always a good idea) and then flash it and let us know.

If it breaks, then re-flash TWRP and restore.

If it works, let us know how it works. :D
[Shield Tablet General] linuxct:
After receiving the notification about the OTA, I turned off the modded, flamable tablet while I tried to update my replacement (which is still with LBL), but, somehow, it always returned an Error while trying to fetch the OTA update. I turned back on the flamable one and, voilà, update gone. I think Nvidia pulled it out, didn't they?
[Shield Tablet General] Zanther_Sera:
So I did this and everything works beautifully. I then put in my 64GB Samsung Evo Micro SD, try to format it as internal storage and it hangs at 20%. I have rebooted several times, tried it several times. I have formatted using my PC, then I insert it and the tablet says its corrupted and tries to format it and fails again at 20%. I have searched around and have yet to find an answer. Can anyone help with this problem? Please?
[Shield Tablet General] adrain:
is this compatible with my Nvidia Shield Original LTE RoW version?
[Shield Tablet General] zarish:
Only if you want to lose LTE functionality. The official version was released and you should use that. This is a modified image from the K1 to function on the Original Shield done by some really smart folks before there were Official ROMs for the Original Shield tablets.

Everything you need for the Original Shield Tabled update to Official NVIDIA 4.0 Android 6.0 is in the below threads:

[Shield Tablet General] Arturo777:
Hello everybody. i just have one doubt about this part of the tutorial:

Battery Drain Fix

Thank you to [MENTION=7171813]sockusminimus[/MENTION] for finding this fix. What you need to do is be rooted and open a terminal emulator and issue these commands in order:

• su

• mount -o remount,rw /system

• chmod a-x /system/bin/logd

• Go wipe cache in TWRP

I'm up to that point of the process and i certainly want to get rid of the battery drain, i downloaded material terminal and entered the commands manually in order, first SU then enter

then mount.... and enter...

the chmod... and enter...

But didn't see anything indicating if i did that right (except when i enter SU it asked for permission of root which i granted of course) But how can i be sure if it worked? Nothing happened at all and i'm eager to get rid of the battery drain. Also, can i remove execute permission from a program like ES explorer or total commander but how can i do that? Hope you can help me thanks.
[Shield Tablet General] drewski_1:
Try the official 6.0 update. I'm getting much better battery life, and actually getting some Doze on it which never worked on the K1 original 1.0 release.

Assume it's also been addressed in K1 1.1 update
[Shield Tablet General] Arturo777:
I tried the 1.1 update, the February one but still had Miscellaneous, i believe the reason was that i had installed like 50 apps, my usual apps. To me that didn't solve the constant drain. So i rolled back to lollipop, and even there i had the nasty drain. The only instance in which i had not seen the drain is by only using the stock apps, or some up-to-date google apps. So my solution was no gaming no nothing. SO i wanted to return to this solution of the logd to see if it makes a difference. SO right now i'm rooted on 1.0 (2.0) Marshmallow and i wanted to try this. In the same way, i'm try app by app of my usual apps to see which triggers the bug in such a nasty way. (Drain of 5% per hour non-stop on standby)
[Shield Tablet General] koop1955:
For what it might be worth the same thing happened to me. As it happens, I have (had now) the same 64GB Micro SD, which now seems useless. Formatted successfully on PC, still fails in the tablet. At 20%.

I tried several utilities, no luck.

Curious to see if anyone comes up with a solution.

I'll also confess that, after trying MM, I went all the way back to Kit-Kat. That is just me and how I use my tablet.
[Shield Tablet General] Arturo777:
So have you tried that solution? Did it work for you?

Could you help me please in those questions i made? it'll be appreciated. I can no longer get the 1.1 update since nvidia pulled it.
[Shield Tablet General] Heartspan:
I just have a few questions, since I feel a bit rusty doing these stuff. My last tinkering was with the 3.0 update..

1. Do I need to update first to 3.1.1 before I upgrade to 4.0?

2. IIRC, this will remove all my installed apps, right?

3. Will the battery drain fix and consequent break of system logging affect the tablet in a big way?

Thanks for this guide, very much appreciated :D
[Shield Tablet General] lofas33:
Can I ask, I have pyrotab and I'm really scared that nvidia will kill it. Now I'm on stock update 3.1.1 (Android L) rooted without TegraOTA.apk. Can I upgrade to update4.0 (Android M) without killing my shield? Is it same as in 3.1.1 just delete TegraOTA.apk or its more complicated? Thx a lot for answers.
[Shield Tablet General] fards:
1 no

2 not unless you factory reset.

Although that's not a bad idea on any significant change.

It will wipe your sdcard. So back it up

3 not seen the new for that fox on the new release
[Shield Tablet General] Heartspan:
Thanks for answering! But for the sdcard, afaik, it'll only get wiped if I use it as part of the internal memory. Correct me if I'm wrong, though :)
[Shield Tablet General] drewski_1:
i think he was meaning the Internal memory when he said SDCard, not External
[Shield Tablet General] Heartspan:
I see. Another question, can I do this guide with a locked bootloader or should I unlock first? If I unlock, my data will be gone for sure..
[Shield Tablet General] marvi0:
Figured it out,thanks for the guide.
[Shield Tablet General] junkinternetmail:
Perplexed...

I was able to update and unlock the MM boot loader.

Then had an issue with flashing TWRP v2.8.7.0 to TWRP v3.0 (i wish i understood what caused this problem better)

I finally flashed a proper SU and the rom below was boot-able.

Additionally, attempts to flash Bliss-v6.0-shieldtablet-OFFICIAL-20160116-1724.zip leaves me stuck at Patching System Unconditionally.

I read that TWRP v3.0 is being fixed so I'll wait on that issue for now.

OTA update is broken so I can flash nightlies for awhile.

Thanks to OP and all people helping in this thread. Very helpful information and informative posts.
[Shield Tablet General] diafebus:
The update from nvidia is already out, does anybody have the IMG?
[Shield Tablet General] diafebus:
hey, one question, I'm trying to install the Official OTA update, but I did this one first.…… and I can't the other one to work, it just stays at the install zip menu forever, any reason for that?
