I've been dealing with SOD (Sleep Of Death) problem since official OTA ICS update. On HC everything (except calendar) was fine, but after official ICS update I was having SOD almost every sleep longer then few minutes.
Tried WiFi/sync tricks etc.
What helped ? Well..
1. hardware reset (Vol+ / Pwr / RotateLock)
2. factory reset (from Settings Menu)
3. full update via sd card (Vol- / Pwr)
OFFICIAL ROM: 7.014.16 - 041.213.01 - COM_GEN1 (ICS)
(Acer_A500_7.014.16_041.213.01_COM_GEN1_1336732099520_45282ff4.zip)
and once again:
4. hardware reset (Vol+ / Pwr / RotateLock)
5. factory reset (from Settings Menu)
...I know that hardware & facory reset are pretty much the same, but...It helped...

I have a A501 and want to get rid of this sod problem. so i took the last "Ice Cream Sandwich 4.0.3 (LEAK)" Rom from http://forum.xda-developers.com/showthread.php?t=1816560 and tried to install the update.zip file from the sd card. When i get to the recovery it starts but crashes after a few seconds. Do i habe to install a different recovery or unlock my bootloader? I'm a little bit confused...can somebody give me a short hint? Thx.

This is probably because of a couple of reasons.
1. You didn't do the incremental update. The available update files are incremental patch files, which means you have to have the others installed before you install the latest. Or at least part 1 and 2 of the original leak.
2. You didn't decrypt the file and remove the "update.zip". Generally, you can't just rename these update files to "update.zip". So the latest OTA you took, you should decrypt it "if it needs it", open in 7zip or Winzip and pull the update.zip file and copy that to your EXT SD card.
The final Official release build, was build .021. So if you still get SOD on .021, then chances are you have one of the later revision tablets, and may have to wait a long time until Acer releases another update, as the later revisions only account for a very small percentage.
Or, you can install the unlocked bootloader, and try one of the newer kernels we have.

Thanks for your replay. So what i did was to install all available OTA updates. Then i downloaded the full package Ice Cream Sandwich 4.0.3 (LEAK) from the site above, extracted the update.zip from this archive and put it on the external sd card. i think that is all i have to do. And my current build number is Acer_AV041_A501_1.021.00_EMEA_DE...so don't know exactly if "[LEAK]Acer A501 ICS (COM_GEN1). Build number 041.126.01" is the same version.
And i tried to unlock my bootloader but the next funny thing is that i tried that Afterota-Tool, but it stucks at 3/4 "Flashing recovery...".
I don't want to loose my 3G-Feature and i saw that nearly all roms are only for A500. Which kernel and rom would you recommend for me?
Looking forward for your replay. Thx a lot!

You current build is cooked my friend. Unless you want Acer repair.
Most of all OTA ICS Updates are Com Gen 1 now. Not sure what acer had in mind. But I believe it has duetch or danish language.
You have to use a 501 update if you want to use 3g and GPS.
My question, were you successful in booting to your system after installing the updates correctly? That is my primary question. If so, make sure you have USB debugging turned on.
But I need to know exactly what your tablet is in now before going further. Does it boot into the OS after running the updates?

I don't know exactly which updates you are talking about. I installed all the available ota updates and the tablet booted correctly after this. If you mean any other update via sd-card i can only tell you that i was not able to install one of them. what do you mean with "cooked"? sorry for stupid questions
My USB debugging ist turned on, firewall and uac off.

Yes, you have build .021 But I am surprised it's not WW_Com_Gen_1
This is the latest Acer build. So stay with it.
Ok, info for you, I am currently working with kernel dev's to maybe get something better as far as kernels, that may help with your SOD if you still have it.
For right now, let us work on things. This may take a few days.
As with Unlocked Bootloader and CWM recovery.
Here is what you should do.
GET YOUR UID NUMBER and write it down.
1. Make sure your Acer drivers are installed.
2. Using After OTA, only install the Patched Bootloader.
3. If you already have the patched bootloader installed (you see Skirlax_CZ bootloader text when you boot),
Did it install the patched bootloader?

So in Afterota i open the tab advanced and there i can choose "browse for custom bootloader" and i can choose between different binary files. I think "bl_ics_ac_v8.bin" or "bl_ics_pb_v8.bin" should be right. What's the difference, what's the right one?

Well, I did things the old fashioned way.
If I am to guess. the first one is CWM recovery included, and the second is Public Recovery included. I never used this tool
I would choose door number 1
BTW, there are other methods to install these things. But let's see what happens. Personally, I don't use these all in 1 tools. Got too many of them in the forums. But, let's see what happens.
If not successful, we'll use My method. And you will learn something in the process.

Ehhhh,,, we're gonna do it my way now.
Ok, keep in mind, it's late in Moscow, and I have a baby that will need bath (long process) and other family duties.
Let's get your computer prepared the way it should always be when dealing with the dark side of android.
Your tab is running now, and that's good. You have a .021 build. Ok. But let;s see if we can make it better.
First thing, and I hope you have Windows XP or Windows 7.
Download and install the Android SDK.
http://developer.android.com/sdk/index.html
Now, next, is the Oracle Java Platform (JDK)
http://www.oracle.com/technetwork/java/javase/downloads/index.html
After you do these 2 things, well, we can move over to the dark side.
Now, after everything is installed, I want you to do something.
Connect your tab with USB debugging on. (Never turn this off)
Open Windows explorer, go to C:\program file (x86)\Android\Android-sdk\platform tools . Open a command window here (SHIFT & Right mouse click)
Then type adb devices in the CMD window. Should show device connected and some numbers.
This tells me the drivers are installed.
If not, You have to install Acer USB drivers from the website.
Then try again.
And that, is as far as I go tonight, too late.
Tomorrow, I will give you a lesson in NVFlash and fastboot.
Rule number 1. Drivers, Drivers, Drivers. This was just to prepare your system.
To save some time, for tomorrow, shut down your tab.
Using a paper clip, or needle or something. Press and hold the pin hole button near the USB port. Hold it. Then, press and hold PWR button. Wait 4 seconds, release PWR only. 1 second later, release the pin hole.
Tab should be black. PWR button white. You may get vibrate.
This is what we call APX mode.
When you connect your tab to your PC, after a few seconds, the PC should recognize this as (Recovery Mode, APX Mode, or Download Mode)
Will need to know what it says. If it says nothing, but gives you an error in Windows device manager, then Houston, we have a problem. And the problem is the drivers. And you need to fix it. You may have to manually select from a list or tell it where the drivers are.
And that is all for tonight Mate. Baby needs bath.

Thank you very much. I installed the bootloader, the recovery and the tegraowner ics rom for the A501. It looks great and it seems that SOD is now part of the history 3G is also working. Great success :laugh:
Thanks for your help and to all developers!

Great! Was waiting to hear!
Not that I demand it, but, it's customary to hit the "thanks" button for those that help
Always remember, you have a "fastboot" bootloader, so if something happens, you can boot to the Fastboot, and do things like install boot.img's (kernels), Custom Recoveries, and some other things. That's why you installed Android SDK. Also, you have ADB capability as well.
Rock On!

In addition: Now i am using "ICS Evil Alex Unleashed Ver 2". I switched because gps is not working when using tegraowners rom. Now it seems, that all important features are working! Thanks a lot for your rom!
I have the official A500 ICS, didn't do anything other than the OTA upgrade, and it worked fine until I installed some additional apps, it started to do the SOD. Then I uninstalled the latest apps I added, more likely instagram, and the SOD went away, till now at least. So, if you can't get it to work, maybe a factory reset to clear out all the apps might help, then, add apps slowly to see find out which one actually act bad.

Great tutorial!
I have a500 with ota ICS. Rooted. Locked bootloader. And working fine, but I think it could be better..
I am used to flashing rom and kernel on my android phone, but it looks like it is a bit more difficult on this device..
If I want to try another rom, should I follow your tutorial first? Or what do I do?
Oh, and what rom do you recommend? - I need fast, reliable and everything working.. Nothing fancy is required
Sent from my A500 using xda app-developers app
I have an Acer 500a I just bought off carigslist. Initially I thought it would be fine but then I realized I was inheriting someone elses problems. I hope someone may be able to help.
Within the first few hours I was noticing google Play crashed a number of times and struggled to update from Market. Somehow the update went through but now there is a system update that won't go through. I'm able to down load it and when i restart the computer to complete installation the screen goes black and says: booting recovery kernel in the corner. I then see a picture of an android and a load bar which after 2-4 seconds the android is on his back and an exclaimation mark is coming out of his belly.
My android version is 3.2
Kernel version
2.6.36.3+
Build number
Acer_a500_7.006.01_COM_GEN2
I'm pretty sure its rooted and i think that might be why its not playing nice with google market and system updates. I called the old owner and explained the problem and he just said he had it rooted and he thought he unrooted it. There is an ap called superuser in aps. (although if it were rooted would'nt I be able to uninstal some of thecrap software it comes with like GOLF HD? -- it won't let me).
The system update is for Acer_a500_7.014.01_COM_GEN2 8.88mb
My problem is all of the force closes I'm getting and the inability to update the system. Any thoughts? I don't have a usb cord to connect it to a desktop either =(
I am a bit out of practice, but...
Should be pretty simple to fix. From what I am seeing, you are running a stock rom. Just because the superuser.apk is installed on the system does not mean it is rooted, but it probably is.
Hit the market, grab "Root Checker" - simple tiny program to let you know for sure if your tab is rooted or not.
https://play.google.com/store/apps/details?id=burrows.apps.rootchecker&hl=en
From what I understand - automatic system updates will fail when trying to apply them to a rooted or modded system. Probably why you cannot auto-update.
My advice at this point would be to:
1) Since you just bought it, just do a factory wipe on it. That will remove all the stuff the prior owner had running on it and will result in a unrooted tab that should be able to get auto updates without a problem.
2) Un-Root it. Once the tablet is unrooted, the system should update without any issue.
As for your Play Store issues - I have never heard of or personally seen any issues caused with installing apps from the store on a rooted device. I have seen a few apps that will refuse to run on a rooted device - but that does not sound like your problem.
I would go with option 1 - just factory wipe the thing. Prior owner may have made tons of changes to the OS that we will never know about, and may have handed you a unstable system. Start fresh. Wipe it out.
Hope this helps you out! Let me know if I can answer any questions.
k thank you so much for the quick reply! I downloaded the root checker and it Is rooted. I did a factory wipe as found in the settings privacy tab when I bought it. That factory reset did not unroot and only cleaned out some of the aps on the device. Is there a better or more surefire way to unroot it? If I reset with the volume down key will it hard reset it?
Thank you for you help!
Draight
Okay.
I am about a year out of practice with my a500 - but from what I am think, if a factory reset still results in a rooted device - the prior user installed a stock ROM that comes pre-rooted.
I highly doubt being rooted is causing the issues you are running into.
At this point if you just want to get back to stock you can probably just install the Acer Recovery Manager from the market and use it to reflash a stock unrooted ROM. Or I see a few guides about how to manually restore back to stock over in the dev section for the a500.
Others will correct me if I am wrong, but I think Acer Recovery Manager should take care of your problem.
Hope this helps!
(Edit: Or you can just download the official stock 4.x rom (ICS) from the dev section and flash that. 3.2 is pretty slow and wonky in my experience, you should be able to just download a 4.x ROM and flash, since you are rooted. Again, I am way out of practice. Don't do anything before reading up!)
(Edit again: I think I was making this harder then needs be. Just flash any stock 3.2 unrooted ROM, done. After you do that the automatic on the air update should kick in for you and update you to ICS)
Thanks for taking the time to work with me on this. I downloaded the program you suggested and tried to use a stock rom. When i went to reboot I had a picture of an android looking up at an exclaimation mark. It was froze like that until I restarted it. Now its back to the way it was, rooted and unupdatable.
I'm probably going to try to just wipe it all over but do i need to plug it into my computer somehow? I dont have a usb connector for the tablet, just the wall charger plugin. can i just download a rom and use the utility to try install it? when I reboot it am I supposed to be pressing the volume button?
I've read a few other forums but usually they sound pretty intense...

Hmmm..
Try the thread I linked two in my second edit of my last post. You just need to grab the stock and unrooted 3.2 - put it on a MicroSD card as update.zip - then reboot with vol rocker and power switch to get the system to flash the update.
That *should* work just fine.
(Edit: Forgot the link! http://forum.xda-developers.com/showthread.php?t=1839313 - there you go)
Thankw, I am going to try it after readingna bit more. Do I need to have clockworkmod installed for all of this?

Nope. Just snag the stock unrooted 3.2 ROM - place it in the root of the MicroSD card as update.zip
Power down.
Power up with VOL + and POWER key held at the same time (you can let the vol rocker go when you see text appear in the upper left corner)
Should be all you need to do. Worst case; it does not work and returns you back to where you are now. Worth a shot.
If that does not work, let me know so I can do a few mins of homework and help you further. Been a long time since I have changed ROMS or had any issues with my a500.
I have bricked it twice by not following directions all the way or just making simple mistakes, but from what I have found there is always a way to recover.
Just tried it. I copied the boot zip to sd card and renamed update.zip and reset..It looked like it was going to download after showing some text in the corner and then an exclamation mark appeared above the androids head... I left it and after a few.min it rebooted back

Hmmm. Odd.
Like I said, I am rather out of practice.
Someone more experienced them me: please help me point Draight in the right direction here?
Thanks for trying to help. =(
I wish that my tablet wasn't having such issues. I;m going to try to scramble around the forums and see if I can find some advice...If anyone has a suggestion please let me know.
Thanks again entropy,
Draight
Update:
So I've been tinkering around with it a bit more and I found a usb cord that plugs it into my computer. I keep finding boken links on this site so Im struggling to find an update I can use to flash to. I downloaded a different super user program which allowed me to temporarily unroot my device. I then restarted it and no root checker says its no rooted and I cannot find the superuser program. I think I have somewhat unrooted it -- but I think the real issue now is the recovery tool. I keep reseting it - hard reset, or factory reset and it wipes everything away but when i try to update it gets about 1/3 of the way up the bar then it stops with an '!' Mark above the droid. Im kind of annoyed at this point and hoping for some new links or some ideas on how to repair the recovery piece.

Go to the Dev section, and grad a couple of the ICS Update roms. You will see them listed for the a500. Make sure they are the FULL update roms. Should be about 3-400mb. These contain a FULL ICS Update Rom, and not a patch file.
http://forum.xda-developers.com/showthread.php?t=1816560
Then, go to the Themes and apps forum. You'll see a sticky that has the Acer Update Decrypter.
http://forum.xda-developers.com/showthread.php?t=1869505
Now, unpack the decrypter, and select one of the ICS Updates. Then hit Start. Take a couple minutes, but you will have a duplicate file with the word "decrypted" added to it.
Wait, you are not done yet.
Using a program like 7zip, or even Winzip, open the decrypted file. DO NOT EXTRACT, just open it and pull the update.zip to your PC's desktop.
Copy that update.zip file to your Ext SD Card of the tablet. Don't be putting it in any folder, just copy it to the root of the card.
Now, you still ain't done.
With the tablet off. Press and hold Vol+ and then PWR. Hold them both untill you start to see text about installing blah blah blah, then release the buttons.
If it completes, and you can reboot into ICS, then you are good to go.
If something fails during installation, then decrypt the other update Rom file you downloaded, and do the same procedure. Usually one of the 2 or three should work for you.
Note these are for the a500, and not the a501.
One more thing. It's advisable you get your UID number before doing these things. You probably won't need it, but it's nice to have written down in case you need it in the future. Inf to get it is at;

Thanks! I am downloading a few of the FULL ICS roms:
*Acer_A500_1.031.00_WW_GEN1 : http://d-h.st/uAy
Acer_A500_1.031.00_PA_CUS1: http://d-h.st/idO
Acer_A500_1.041.00_WW_CUS1: http://d-h.st/Yt5

*Acer_A500_7.014.16_041.206.01_COM_GEN1: https://docs.google.com/file/d/0B_bk...hVc1RVcHc/edit
The I downloaded the ones ending with Gen1. Once they are downloaded I will continue with the instructions. Thank you so much for your help! I will post how it goes later tonight.
Draight
I just decrypted both:
*Acer_AV041_1.054.00_WW_GEN1:
*Acer_A500_1.031.00_WW_GEN1
Both get get to the third bullet quickly and the bottom says DONE! It takes like 4 seconds. I don't think the Decryption key of $12 is working
[*] Opening file: Acer_A500_1.031.00_WW_GEN1.zip
[*] Decrypting using key $12
[*] Writing decrypted file: Acer_A500_1.031.00_WW_GEN1_decrypted.zip
I try to extract something from the decrypted file and it says the file was not downloaded properly and I should try redownload it...it says its not a proper archive
wahoo!
So that worked! I down loaded the file Acer_AV041_A500_1.033.00_PA_CUS1 and extracted the update. I palced the update on the sd card and booted with the power and sound volume pressed down. it went through the installation procedure and restarted twice before saying it was upgrading my aps and BOOM its got ICS and everything looks great. Thank you so much for your help and I hope that this paper trail is able to help someone in the future
My problem is that I'm on ICS and I'm rooted, but I just can't download a custom recovery. I've tried, and I haven't gotten anywhere

I deleted a folder in /data that had some installed software in it. Once I deleted it, the N7 immediately began spitting FCs at me, Aldiko keystore, the WinnIME app, some .pngs, all FCs.
I rebooted and it hangs on the Google screen. I can get into the bootloader by holding volume down, but the menu usually navigated by volume buttons stays on Start and the power/enter button does nothing. No recovery, obviously.
Most depressing, fastboot and adb do NOT work. The closest analogs to this problem I have found through this search is people who accidentally erased their bootloader. It looks like mine may be corrupted, which could end up being no better.
I am out of town and away from my primary Android computer. The one I have with me is Windows, with an Ubuntu VM that has the SDK and confirmed working ADB and fastboot usually. No dice now, like I said.
When I plug in the tablet through USB, the Windows host attempts to install MTP drivers and fails. I would try and install the Windows SDK and try to get a connection through some of the Windows drivers, but the internet where I am cannot take it.
Any ideas? I am thinking the device is toast, but since I would be the first I have heard of to be able to get into the bootloader and still brick, I thought I would open it up to the community.
Details: I HAD CWM, no more. Stock, rooted only.
is there no nv flash for this device.. this is what you need. to boot into nv flash and flash the boot-loader.. .. I think this is the only way. There is another thread that talks about this.. Not sure if they managed it or not but they were very close i think..

Yeah. I used NVflash on the wife's transformer 101. I saw that thread, but i think the resolution was that they finally got close enough to find out they didn't know what they were talking about.
That sounds worse than I intended it. I mean that they simply weren't very experienced NVflash users and so they didn't know what they were missing until they worked at it. Seems a while away, if ever.
I have a second Nexus 7, i am wondering if i can do something with the hardware, maybe. Is all of the storage in one chip? I have the 16 gig, i seem to remember the 8 gig has n actual emmc.
I am going to try and stay away from devices with virtual sdcards from now on. This was just a folder in storage, WTF? I am not even sure how this is possible. Hardlink mayhem, presumably. The device had only ran stock.

yea there is only one storage device inside the nexus.. its all symlinked
If you could get the driver going, send a adb reboot-bootloader command, the bootloader should work then.
Will the next nexus have a longer screen?
Same problem here.

Hi, everyone!
I've got the same problem with my Motorola Razr D3 (XT920). After a system update, something bad happen while the system tried to install the last patch realeased by Motorola. I still can access the bootloader but nothing is working.
So I wonder if any of you guys have figured out how to reinstall the bootloader.
(I hope this is the right forum, if not please direct me to the right place as I was really unsure where to go since this device does not have it's own forum)
Diablotek 2 Tablet D2-721
Hi, I recently got a D2 tablet from Micro Center. I know it is a cheap tablet and I am not expecting great things, I just want to be able to customize it a touch so that things run a bit smoother.
I have already rooted the device, removed bloatware and installed Google Play, so I have things going a bit. I was just wondering if anyone knew of some custom ROMs for this device and/or a way to change the resolution/screen density. I have found some places for these things but only for the slightly older models that are running ICS (not JB) and have slightly different hardware specs, so I know it can be done I just cannot find any for the newer versions.
Any help is greatly appreciated and many thanks in advance!

[Edit] Also, does anyone know how to reboot this device into a Recovery Mode.
Did you try < adb reboot recovery syntax > ?
No, I have not but thank you for the information I will get around to doing that and let you.
Many thanks!
Device is not being found, but the computer does recognize it when I plug it in and My Computer will show it if I Turn on USB Storage.
The recovery command returns the message "error" device not found"
The device command returns a list with nothing showing up.
Any ideas? I have found a couple of ROM's but I need to be able to flash a Recovery mod and/or get into recovery to do anything. Trying to boot into recovery through any app just sends the device into the Android error logo upon boot and I cannot do anything.
Also, does anyone know how I would go about changing the screen resolution and/or density? Or perhaps can point me to some material that can show me how to do this?
I still need to get this tablet into recovery and find a custom ROM for it but most of my problems would be alleviated by adjusting my screen.
Well, I used the LCD app to adjust the density. It is more of a workaround than a fix but it will do for now.
Now, about getting this thing to boot into some sort of Recovery. It seems like this might be tied to the boot loader? Is anyone aware of a bootloader I could flash for this? Or can this be adjusted by modifying a system file? Or am I way off base and need to go about completely differently?
Well, the LCD app put the device into a boot loop and without a way to get into a recovery mode I am at a complete loss.
All the boot loop fixes I found require booting into recovery mode. ADB will not recognize the device while in a boot loop and neither will any other utility that I have found. Even the manufacturer's utility for flashing the stock firmware will not recognize the device in a boot loop.
Does anyone, anyone, have any idea of what my options here are? I have been searching and digging through forums for hours but to no avail. Any help is greatly appreciated, thank you.
Deleted, somehow this got posted on the wrong topic. Sorry for the inconvenience.
same problem
Hey, dont feel bad, Im in the same boat. I dont understand how the D2-721 doesn't have a volume -/+ keys, Ive probably skimmed through 5 different forums, spending about 1 1/2 hrs on each one, just reading. Trying to find out how to install custom recover and root on both my d2 pads, I have the 721 and 912, with no luck, the root script for the 721 wont even recognize the tablet, but the debug is working. ugh

i just picked up this tablet...and finally figured out how to get play store on it....and...now i am too wondering how to install a custom recovery.
I have an app called EzRecovery on my s3 that falshes recoverys, but that says its for the s3...guessing it wont work on this tablet
Yeah, I searched far and wide but this just isn't a popular tablet so there isn't a whole lot of customizations for it. The few that I did find were for the slightly older ones which would not work for this one. I was able to root and install Google Play but I never could find a custom ROM for it and I never could get a recovery mode for it.
Be VERY wary because without a custom recovery it is easier to brick this tablet than most Android devices. Which is exactly what happened to me. I took it back to the store and got the next tier up which was +$50 more, a Lenovo tablet. Heed my advice and be careful, good luck to you both.

How did u root and install Google play?
If anybody bricks his/her device and has only the APX mode available or is trying to get an nvflash utility for a Tegra Note 7, now the solution can be found: the Advent company has published a full package including a nvflash working with the Tegra Note 7. Moreover, the package contains a signed bootloader and bct and all the other parts of the entire storage (including the system partition for a 4.3. JellyBean).
It can be downloaded from their website of adventcomputers.co.uk in the downloads section (I can't post links yet), select Product range: "Advent"; Product type: "Tablet"; and then choose "ADVENT Vega Tegra Note 7", do not be mystified by the "driver" type and download the "Advent Vega Tegra Note Factory Image (4.3)" (about 641 MB package)
Many thanks to the dev and support guys at Advent (Dixons retail plc), because they have put the final cherry on the top of the cake. The Nvidia Tegra Note 7 is now not only a top of the top devices regarding its power, but this package renders it into an unbrickable device.
(note: I'm NOT affiliated with any of the companies, I just bricked my device and had no other mode available than the APX mode. I'm posting this post due to the abovementioned reasons, because I find this quite and important source for further hacking(orig. meaning) of the devices. In fact I regard this as an utlimate source for development on this platform.)
I have tried the package (including the batchfile, that does the automation), it works for me on my Advent Vega Tegra Note 7, however Im not sure if it will work on others (EVBA for example), so please feel free to test and post your experience underneath here.

Thanks for the heads up. I tried it on my bricked dodgy manufactured tablet and I was able to get the device to a new level but it still crashes trying to boot the system partition. Least now I have fastboot.
With the nvflash recovery tools you can replace the images to suit say bat-recovery or latest boot.img with menu options the older version doesn't have.
Wait what?! Why havent I been notified?! And subscription to my own thread has been lost?!?! O__o ill take a look at this!!!!

HEhehee. This nvflash recovery is only new to the scene so I didn't get time to check it out then inform you Shaky.
In my opinion our community can rehash these tools and make a better recovery.

Reopening a closed thread?
There is a thread I would like you to reopen, since the state of things has heavilly changed. The post I would like to post is an quite important one, while it may contain a link to a commercial site, it also points to an nvflash utility working with Tegra Note 7, including signed bootloader and BCT. Moreover, the (non-purchase and registration free) download package is made by a commercial partner of nVIDIA with (AFAIK from their support) full consent of nVIDIA. For the Tegra Note it is the last missing bit for the full controll of the device starting from APX mode up to the various other run-modes.
Im not affiliated with neither of the abovementioned companies, I just bricked my device and had no way to recover it since APX was the only rescue, so they published the whole package (for 4.3 JB). I think mentioning this as well the link to the package is worthwhile the post, but I do not feel that starting a new thread would be correct.

Ok, I need some help if anyone can.
I erased the boot file on my Nvidia EVGA Tegra Note 7 P1640 tablet and now I'm stuck. I had set usb debugging on in the tablet and as far as I know, it's still on. I have tried everything I can think of and nothing works. First, there are 3 driver_install.bat files in the Vega7\usbpcdriver folder. Being that I'm running windows 7 64bit with an AMD processor, I select driver_install_amd64.bat and it fails wanting $P4ROOT$ to be set. I may be wrong, but I set it to D:\Android\Vega7 (in the install_driver_amd64.bat). Please correct me if I'm wrong. Second, if I set p4root to D:\android\vega7 (where the Vega7 folder is), it fails with "NT DDK at //sw/tools/ddk/nt6/6001.18002/... is not synced" and fails. I have no idea what to do about this. If I goto the vega7 directory and click on flash_signed.bat, it stops at >SN.txt and just sits there. I thought I was fairly computer savy, but apparently I'm not.
I've followed the instructions as written up to the point it freezes up on me, however there is no info on what to do if the batch files fail.
I can get the tablet into APX mode in the device manager, but the drivers are not loaded. I can load the drivers in the usbpcdrivers folder, which installs "Nvidia USB Boot-recovery driver for Mobile devices", but still can't get the flash_signed.bat to go any farther than >SN.txt. (I turned echo on in the bat file so I could see what was happening)
So please, anyone, help. I've only got one hand full of hair left and it's about to go too.
Always use usb without option for power charging.
Change USB port if not try on different computer, I was stuck on my one when I try do flash, go on my girlfriend laptop and done without any problems.

Can't use usb without power. The tablet will not stay turned off now and because of that, the battery won't charge enough to usb without power from usb.
I've even plugged in the charger and gone into boot-loader and clicked on shut down, but it still won't stay off or take a decent charge.
I have tried a different computer as well as different ports with the same results.
btw, thanks for replying.
As I reread the posts, I noticed rheingold's post at the bottom says he's not sure if this will work on the (I believe he meant EVGA) model. Can anyone verify it works on EVGA?
Solved. Bad USB cable. Unbelievable! I guess the original cable only works when it wants to. Used usb cable from old kindle with complete success. Fully restored to 4.4.2, rooted, and sd card fixed. I'm back in business. Gotta love those rootjunkys super tools.

Nice work mate. I am speaking with Nvidia too see if they will do factory images like the Shield but waiting on a response for that.
Also OTA 2.4 is now Live as of 5 minutes ago.
It seems the USB cables are not of high quality just like the ports.

Having the same issue here.. anyone?
I have a copy if its needed still.
Today, panic stations as I thought I had bricked my Advent Vega Tegra Note 7.
I had updated yesterday to KitKat along with additional OTA updates, but decided
to go back to 4.3 to capture the update after main KitKat update (2nd of 6 updates [EDIT: forgot to cap that one]).
I unlocked bootloader via fastboot, then flashed system.img (4.3 from Advent) and then the TWRP
recovery.img EDIT: Also locked bootloader..
On boot, it got itself stuck Powered ON at the TEGRA NOTE (white on black) screen, all was doom and gloom.
I finally figured out that holding down Volume+ then pressing the power button quickly and then
pressing again (whilst still holding the volume+ button down), I could get into the recovery menu
to access TWRP. In TWRP I did a factory reset and hoped for the best.
On reboot, all was still doom and gloom. So I thought maybe it might be necessary to have the
appropriate boot image (rather than the 4.4 boot image), and so flashed that, and Voila,
everything is hunky dory again.
I seem to have lost ability to use nvflash (APX mode) after original 4.3 flashing (which I could access
on the device doing the same dance as above but pressing both volume up and volume down keys before power).
My USB driver Vender ID and Product ID's below, I seem to have two Fastboot Id's, presumably one for stock recovery
and the other for TWRP (I blanked last 5 digits with x's just in case they could be used for nefarious deeds).

Anyway, perhaps above is all known to you old salts, but for a newbie like me, is perhaps of use.
Also, thanks for the link
You can access APX by pressing Power plus Volume down and Volume UP at the same time and holding them.
Thanx hacktrix, I could access APX OK (was stuck with power on, ie could not power off, the dance described allowed me the access both fastboot and APX).
The problem was nvflash via flash_signed.bat.
