Shield

Hi, same since 1st september, black screen+APX forever. I'm on Linux with nvflash version from Transformer LinuxTools.

Usually no need of drivers on linux so I give it a try. With '-r' stay on [resume mode] message, '--go' Error 0x8 and '-bl bootloader.img' Unknown device. Where did you find your nvflash version ? maybe mine is wrong or too old.

But what is fun is when I disconnect the Shield, I have a greetings from nvflash command line so Shield is alive...

Last thing I did with was playing with DS4/PS4 controller wired on usb by an app bought on store. Not rooted so I'm confuse but the Shield was plugged in charge since a week maybe the mistake. So I try to manually update/boot through APX, no way with pwr & buttons.
[Shield Tablet Q&A, Help & Troubleshooting] Deleted member 4473400:
I found them googling and I tried tegra3 and 5.1.x (that I understood it is for GPU NVidia). So I haven't tried right version i think... I don't know even which one are good for me :P I'll see on linux what happens (if I can install it)
[Shield Tablet Q&A, Help & Troubleshooting] Bogdacutu:
TDP 3.0r3/4 have nvflash and APX drivers (and I'd assume the Jetson TK1 OS images have them too). but, as repeatedly mentioned on these forums, these are all useless without the SBK that is unique to each device, and that only Nvidia knows

can you dump a copy of the bootloader and post it?

[Shield Tablet Q&A, Help & Troubleshooting] Bogdacutu:
check the factory image thread, the bootloader is included in every factory image

Okay , the bootloader = fastboot functionality or no? i have a few other lines out looking for ppl to dump parttions/blocks

what is the /dev/block/platform/sdhci-tegra.3/by-name/? for the bootloader?

[Shield Tablet Q&A, Help & Troubleshooting] Bogdacutu:
there are multiple relevant partitions included in the blob, such as EBT and BCT. however according to http://projects.pappkartong.se/a500/, the bootloader is encrypted, so dumping it is useless

Hey guys. According to what i read u are some Kind of experts?? Please halp me!!

I have the Shield Tablet deactivated by nvidia(The New one too)

I have an unlocked bootloader but not USB debugging because after unlocking bootloader the device kill switched itself..

Any hope for me?? Please by my hero!!:)
[Shield Tablet Q&A, Help & Troubleshooting] LOCKDOC_UA:
Same here. I am stuck on Nvidia boot logo. And can get into APX mode only by pressing Vol Up + Power.

But funny side is it happend not due to killswitch but (as far as I understand) but due to my stupidity )) :

- Unlocked bootloader

- Downgraded to 4.4.2

- Flashed TWRP and Rooted.

Then I wanted to completely wipe all data and choose Advance Wipe and checked all options (lets say partitions) to wipe (in TWRP). After wipe is complete I rebooted and stuck on Nvidia Logo.

My new tablet will arrive only in about one week (( So not a big deal but I will be more than happy if I can resurrect an old one.

okay the skinny, maybe xD

right now i'm trying to get fastboot written back. do you know if an sdcard [external] can be booted with a correct and correctly structured/populated partition layout on this device ?

probably not, don't see why they would bother checking anything but the internal memory

So.. Nvidia just killed my tablet for no reason and the replacement one is in indanapolis according to ups..

is there a way to retrieve my data, or the killswitch deleted that ? :(

My 2nd shield also got blacked out... I unlocked bootloader and downgraded the system with nvidia support authorization because the latest update caused a problem. Installed the first stock OTA it worked, but the problem was still there, I updated the tablet using the android update tool from the OTA and it got blacked out, had to return it for rma (this was before battery recalls).

My 3rd tablet 100% stock and official got blacked out for hours just like that. Put it to charge and didnt charge, no power button, no vol+- + pwr button nothing would make it even turn on.

After some hours it just turned ON normally with pwr button...

ps: Jeez, the device is so god damn defective that I had 3 RMA's (always got a new tablet) and the 4th from battery recall is also defective and has wireless problems. FOR F*** SAKE...

[Shield Tablet Q&A, Help & Troubleshooting] Prokysoft:
You need press the right buttons... If you are in APX mode, press POWER at least 40 second to definetely shut down the tablet. Wait a moment. Now press VOLUME DOWN (the more distant volume button from that POWER button) + POWER. You can press that 2 buttons in same time, or VOLUME button first and imediately after that press POWER.

To APX mode you can get easily if you dont press them right . Just try it few more times util you try more high level actions.

If you are 100% sure that bootloader mode didnt work, theres some drivers for "APX": http://xdaforums.com/showthread.php?t=1054492

[Shield Tablet Q&A, Help & Troubleshooting] hacktrix2006:
Unlike the Tegra Note 7 which was only fixable via APX after an OEM White label released the files we are now dealing with nvidia.

So unless Nvidia releases the APX image files a signed APX driver and the ODM value for which your send to the tablet when its in APX mode you can not recover your tablets.

So the only way to fix them now is to RMA with Nvidia.

Hello guys!

I have send my motherboard to drims75 from Austria.

It was already stuck in APX mode no change to reactivate.

Today I received my motherboard back and rebuild to my tablet.

It is working now with android 7 serial number changed (fully official nvidia update no problem) also the battery type is showing now B01.

All I can say now drims75 has really done the job and is working now.

Always when I ask question to drims 75 I get very fast answer with pictures.

So please thrust him he can repair.

I made photos from my repair process if you need any information please ask!!

I am so happy!

Best regards from Austria to Drims75 and all of you!!!

[Shield Tablet Q&A, Help & Troubleshooting] Mr_Armageddon:
Looks like I have also been bitten by the Nvidia "Kill Switch". My 32GB LTE enabled Shield tablet (post battery replacement) was working fine until I went to boot it up last week...nothing.

Made sure it was fully charged, battery indicator shows on screen, but trying to boot gets... nothing.

Tried to to boot into FastBoot (Power+Vol Down)... nothing.

Pressed Power+Vol Up... USB to PC recognizes it in "APX" mode, but can't do anything from there so... nothing.

Contacted Nvidia Support, they said I am past the warranty period so "sorry", but won't fix it. Looking to the forums for help. Any ideas?

Tried that, and multiple other variations of button presses. Only thing I can get into is APX mode. Nvidia support says they can't / won't fix it, so looks like its on to a different device. :(

[MENTION=4937137]Bogdacutu[/MENTION], so finally my tablet got bricked too, tried all possible solutions, I read your reddits and found that a guy had blob which we can flash via nvflash and wheelie, but you had said it requires SBK, so now i have SBK of my device, the APX drivers are installed, the NVFlash, everything, just need a someone with immense knowledge and a helping hand, together we all can bring back the dead STs
[Shield Tablet Q&A, Help & Troubleshooting] hacktrix2006:
How have you managed to work out your SBK?
[Shield Tablet Q&A, Help & Troubleshooting] THEHOLYG0D:
Yep, went through all the Nvidia APX cases of almost 7-8 devices only to find that.

---------- Post added at 06:11 AM ---------- Previous post was at 05:46 AM ----------

For all the cases, the OEM released APX packages to flash, maybe we will have to force Nvidia for releasing it, maybe starting a petition or something...
[Shield Tablet Q&A, Help & Troubleshooting] hacktrix2006:
You do know the SBK is unique to each device, also on the shield tablets after the TegraNote 7 moved to a ODM key which only Nvidia knows as they are the only OEM for the shield tablets. The only way I can see people recovering their tablets is with a hardware programmer and hex edits after getting a dump from a working tablet. That method relies on if nvidia has allowed a low level programing on the device in the first place.
[Shield Tablet Q&A, Help & Troubleshooting] THEHOLYG0D:
[IMG=":3"]https://i.imgur.com/vBf6TWA.png[/IMG]

If this is what SBK then, I have it ..
[Shield Tablet Q&A, Help & Troubleshooting] hacktrix2006:
Since the Original Nvidia Shield Tablet the Nvidia APX now expects use of the ODM key for anything. Nvidia stopped using SBK after the Nvidia Tegra Note's.

My only guess for the reason why is because the original file was leaked by OEM's, thats why you see only Nvidia versions not Advent EVGA etc. The ODM Key on the other hand is not unique to each device but like a Master Key to which only Nvidia has access to it.

I said this at the beginning of the thread seeking an SBK key is useless your need the ODM key or a Hardware Programmer to see if JTAG/UART Programming is enabled on the SOC chip so you can dump the whole SOC's storage setup edit the areas that need editing to flash back to a bricked device.

I've had the same thing happen over the past few days. I restored all the way back to stock unrooted and still have random reboots. Wondering if it could be a recent framework update - or maybe battery related? I've had my G2 for 18 months with no trouble up until the last week.
[G2 Q&A, Help & Troubleshooting] DaveTN:
same thing happened a few weeks ago to my Wifes Verizon G2. They sent her a new one and within a week or so it was doing the same thing. Random shut downs, reboots and lockups. Sometimes even doing a simulated battery pull would not restore it unless we pulled the sim card first. Got the lollipop update and still had the problem so we took it back to Verizon and they replaced it again. First replacement was a refurb, second was a brand new phone. No explanation as to what was the cause.

[Nexus 5 General] apatel321:
When I start my day with my phone my ultimate goal is to get the most out of my battery. I have a Nexus 5 which is great phone but one downside is that the battery which is 2300mah can barely get you through the day. One way to help this issue is to under volt your CPU, the nexus 5 has a snapdragon 800 CPU clocked at 2.26GHz which is power CPU but at times it can run a bit hot and use more juice than it needs. By Under Volting your CPU your device will run much cooler without losing performance. (Warning if you go too low with the voltages your device will freeze and randomly reboot. ). The voltages than the nexus 5 ships with are a bit high I've been able to under volt up to -75mah without losing any performance however your experience may be different. To under-volt your device you need to have a rooted phone with a custom kernel installed. Franco, ElementalX, and Codeblue are few a few of the many kernels you can use with the nexus 5. I've been using ElementalX as my kernel for a while now, although Franco is also a good one. I use the ElementalX kernel app to manage my voltages, its a paid app but its definitely worth it. you could also use the Kernel tweaker app to manager voltages as well. I've set the governer to elementalx and i set the max cpu freq to 1574MHz, and the max screen off frequency is set to 729MHz. Don't go to extremes take small steps. Please let us know your results here.

This is what i have so far.

300MHz = 650mV

422MHz = 650mV

652MHz = 700mV

729MHz = 720mV

883MHz = 740mV

960MHz = 750mV

1036MHz = 760mV

1190MHz = 780mV

1267MHz = 790mV

1497MHz = 830mV

1574MHz = 845mV

1728MHz = 875mV

1958MHz = 945mV

2265MHz = 1000mV

Edit:

my pvs is 2

300MHz = 650mV

422MHz = 650mV

652MHz = 700mV

729MHz = 710mV

883MHz = 730mV

960MHz = 740mV

1036MHz = 750mV

1190MHz = 770mV

1267MHz = 780mV

1497MHz = 835mV

1574MHz = 840mV

1728MHz = 875mV

1958MHz = 965mV

2265MHz = 975mV

Just remember in a couple weeks if you notice stability issues or your phone rebooting, it's probably because of these changes.

Personally I value 100% stability, and I'm already able to achieve the same battery lifeout of default clocks and voltages as well as stock ROM and kernel. Such as these 5-6 hour SoT examples using 40% Adaptive Brightness.

[Galaxy Note 4 Q&A, Help & Troubleshooting] thedicemaster:
it depends on what you consider being able to root and unroot.

a Samsung service rep told me you can unroot once through a Samsung service centre to keep your full warranty.

there's no limit to how often you can root and unroot your phone yourself, but unrooting your phone yourself doesn't restore (full) warranty.

as mentioned above, the counter is only there to give an indication of how many times you've modified the software, it's not going to self-destruct once it reaches a certain value.
