Stuck in APX mode - G Tablet General

powered up with PWR and (-) key and wont come out of it

Hold the power down for at least 5 seconds. You should see the screen go completely dark (better in a semi-dark room, as it's easier to see).

still stuck
tried your solution, nothing.
let it charge overnight to make sure I wasnt being a total scrub and the battery was dead....nothing
Any other suggestions would be greatly appreciated.

skip this, finally woke it up...on to next problem thanks all

When I first tried to flash to 1.1a, something like this happened. I don't think it was the ROM -- I think something malfunctioned inside the file system.
It was in the continuous Off/VS Birds/G-TabletLogo loop and even the power switch would not turn it off!
I wound up flashing CWM, and when I got into CWM I re-partitioned and re-formatted everything and then was able to successfully re-flash to TnT 2.2.0. (With the file system fixed, I am guessing I probably could have gone back to 1.01a if I have wanted to.)
Glad you are back working.

ARGHH!!
So has anyone found a definitive way to get these devices out of APX mode? I did a full restore on new device to clean up all the partitions and such, now nothing seems to get this thing to come out of APX. I suppose I could power it up with nvflash and leave it on the nvflashing screen until the battery dies, but there had to be a better way than burning the battery down overnight...
I have tried all sorts of combinations of powering on and off, is there a magic sequence lol...

Please don't hijack threads. There are LOTS of threads about boot loops. Check out some of the boot loop threads.

I was able to finally get the device unlocked and running much better. I used the nvflash recovery to get back to stock, then used Z4Root to get the device rooted stock. The rooting seems to have un-apx'd the device, and it works fine from there. So I would recommend keeping z4root on your drive so you can install it and root the device if it gets stuck in apx mode lol. It's a dirty hack but it worked for me when nothing else did.

Both of you,
I don't see that the thread was hijacked -- both of you are/were stuck in loops. Or at least something I think have a common cause.
What I was saying in my earlier post is that I am seriously wondering if the boot loops are caused by problems with the file system. Say, the system malfunctions or a flash makes something so it can't find the files it need to start.......
From my reading, it seems like most of the loops wind with the file system having to be fixed, or a new mod flashed over it, etc.
If we could determine that, perhaps we could know if loading CWM and fixing, or some such -- might save a tablet w/o having to re-flash.
Ideas or opinions?

what worked for me is holding down the same buttons to getting into apx mode.
both +/- volume buttons and then power until the screen turns off.

May I ask how you got it started up? The only way I can get it to start is to NVFLASH. If I turn it off again, it'll be stuck in APX mode...

Black Screen After bad TNT 5.0 Lite Install

I stupidly installed TNT Lite 5.0 before reading the instructions. My gtab locked at white screen. I panicked. Did a full restore using Nvflash. That put g-tab to 2638. But when I shut off power I can get nothing but a black screen when powering on. The only way to get the tablet to function again is to flash another full restore, and then same problem occurs when I shut down. I cant update because the tablet screen goes black when attempting reboot. I've been reading posts here in the developers forum all day and I haven't come closer to solving my problem, so I need help from someone smarter please.

yes check the first post in the lite thread. It is linked as APK 3588
I downloaded it, but I am not sure how to use it with nvflash as compared to the restore which was relatively simple using the included bat file. Am I missing something or am I just a hopeless Noob?

Hmm?.. Seems there are a lot of users trying to prove the GTAB is in fact Brickable..*lol*
It is NOT!
Go here:
http://forum.xda-developers.com/showthread.php?t=861950
Yes I feel dumb about it. I did read that thread before posting. I did the restore. I can get the gtab to boot up and it is usable.......until I power down, then the only way to use it again is to reflash the restore again. I mean its usable. Not really bricked, really, but I am frustrated because it seems like I am missing the solution.
I used the nvflash from http://forum.xda-developers.com/showthread.php?t=861950 to prep my gtab for 5.0. Once it flashed and booted to the OS, I had it join wireless, then it prompted to start the update to 3588 immediately. Have you tried this?
Yes it downloads the update but to complete the update, it must reboot. When it goes to reboot then the screen goes black and then nothing The only way I can get it to work again is to nvflash it to the complete restore I have been going round in circles with it for hours and hours

Been there.......months later the tablet is still there. I can not power it off or reboot it. I bought another tablet and use "the unbootable" one at home where it sits in a dock until needed.
I have tried every nvflash recommendation out there...
There are about 4 or 5 tablets like this. Most have either been returned/swapped out or set aside and no longer used (from my reading of others with the same problem).
I can get it to boot by formatting partition 2 so if it ever goes off or I need to "update" it I turn it off.....connect it and nvflash it...holding volume + if I need to get to recovery. If not...once nvflash sends the bootloader over and formats partition 2, the device boots.
Something on mine is preventing the bootloader from booting.....the nvflash sending it over executes it and the tablet runs......

I got the same problem. I can only power my gtab by doing nvflash, and if i reboot, it only goes into apx mode.
Ouch. That has stopped me in my tracks. It's really bad news.
"Something on mine is preventing the bootloader from booting.....the nvflash sending it over executes it and the tablet runs......"
That's my problem exactly. My wife is going to be very upset. I thought I could keep her gtab updated without bricking it. Oh jeez that's exactly what I've done..........
Suggestion? don't do the update after you nvflash.. let the device boot up normally and put a different ROM zip file on the SD via USB.
Calkulins new ROM is based in TnT is super smooth.
http://forum.xda-developers.com/showthread.php?t=985705
From there try to reboot into recovery mode with an app like quick boot AniReboot and flash the different rom.
It may be the ROM you're trying to flash is corrupt.
I did the same too. . An didn't read the fine print. After getting the info
on how to fix my bricked gtab. Also, I had to do some Googling on apx
USB drivers for windows 7.
Long story short.. had a few pints. .. got it back to stock and installed tntl 5
The next day.. I'm using it now and I'm happy. Time for another pint.
I thought I bricked my GTab, after several hours of tweaking I was
able to flash it and run TnT Lite 5.0 now. Here is the procedure I did:
a. nvflash to stock rom. download the usb driver for windows 7 here and install (link from post by syntrix) : http://developer.download.nvidia.com/tegra/files/os/tegra_ventana_froyo_20110207.msi
b. grab the stock rom from the post by roebeet, choose "nvflash_windows_20100500.zip" and ""nvflash_gtablet_2010110500.zip": http://db.tt/Wm25t7U
c. following roebeet's instruction, put Gtab to APX mode (volume down + power on), run nvflash_gtablet.bat, should flash the rom fine.
d. boot the Gtab after flashing, should be able to run the original stock rom.
e. download the 3588 stock rom from this thread:http://forum.xda-developers.com/showthread.php?t=842000
f. run recovery (volume up + power on) to upgrade to 3588 rom, remember to make a "recovery" folder with "command" (check the prefix and see if is name "sdcard") and rename the downloaded 3588 rom to "update.zip". Put both to the root of the sdcard.
g. now you should have 3588 rom after the recovery
h. download tnt lite 5.0 rom and run a recovery. you will get stuck at a black screen. Just reboot and enter recovery mode again (volume up + power on). do a "wipe data" and reboot. Then you will be able to run TnT lite 5.0. In the recovery mode, the "power" button is "enter", not the "home" button in CWM 0.8. Anyway, just follow the instruction on screen for button layout.
Thanks. I have actually done those and would do them all but G-Tab will only boot once after flash (step d) after that if I power down, I gotta black screened brick until reflashing original ROM again. It is impossible for me to do step "F" from Gaspra post
and with that I give up. I ordered another G-Tab, and I'm using the old one as a plant stand. Who said this can't be bricked? I managed to do it.
Send it to me. I'll pay shipping.

Relock US Xoom Tiamat 1.4.4 resulted in hanging at Motorola logo

Hey guys I was having some problems with my xoom's wifi on Tiamat's 1.4.4 so i decided to relock the device and use stock.
It's a US model and had build HMJ37 but i decided to follow this thread
http://www.xoomforums.com/forum/mot...4600-thinking-about-unrooting-read-first.html
I downloaded img build HRI66 and followed all the steps and it was ok. Then, i rebooted and now my device is at the motorola logo's dual core screen. Everytime i manually reboot with power and volume up it automatically reboots the device instead of shutting it down, it literally won't shut down and keeps hanging at the moto logo. It just keeps rebooting and getting stuck at the motorola logo. I then unlocked again, and performed the same process with the HRI39 img and still got the same problem
So im stuck. Please help me out guys, i'm in serious ****.
So you have gone as far as the "fastboot erase cache" and "fastboot oem lock" right? This is kind of funny because I tried to install Tiamat 1.1 ROM tonight and ended up going through this HUGE loop of problems.
Here's the problem I had: some time ago I installed ROMManager from the market. I thought it would be easier. It SHOULD be easier. I let it update my recovery to its own version 4.something. It allowed me to SORT OF install the ROM, but I wound up with some persistent system files that weren't getting wiped and a bcm4329.ko version mismatch.
This stumped me for a long time because all I could see was an "Error" message where I was supposed to be able to toggle the wifi on and off. I tried rolling back to my previous ROM. No go. And the culprit the whole time was ROMManager's CWM.
I tried rolling back my recovery.img file to the Tiamat version recommended in this forum. I kept getting all of these crazy "could not mount" errors for pretty much EVERYTHING. I thought my recovery partition was effed. So I rolled back to stock. Followed pretty much the same instructions you linked to.
From there I was able to boot into the stock OS. WiFi worked. I breathed deeply for a minute or two then dove right back in.
If I was in your position I would (and I did, though not from a boot loop) boot into fastboot and unlock the bootloader again. You can do it by holding the Vol down key as the device boots. When fastboot loads type "fastboot oem unlock". Press the Vol down key then the Vol up key. Do that again. Your device is unlocked now! Hooray!
Now you need to install a recovery.img. (I just did this too.) Get the .img file here: http://forum.xda-developers.com/showthread.php?t=1074979
Boot into fastboot again. Put the recovery img file you downloaded into the same directory as your adb and fastboot executables (if you haven't already linked to them in your PATH). Type "fastboot flash recovery recovery-lotsofstuffhere.img". Type "fastboot reboot". 2 seconds after the Motorola logo pops up press the Vol Down key. Then press the Vol Up key to enter recovery.
Ok, here's where I found out what a dumbass I was. I got all of the stupid "can't mount anything" errors again. I thought, HOLY ****. I just did all of that work, spent hours troubleshooting and reformatting and bringing it back to stock and flashing the custom recovery all over again just to run into the SAME error. I really thought I was screwed. Then I found some forum where a guy was complaining about the same error. He realized he was getting it because his sd card was half-way out. I thought - "SD CARD?!?" Some guys told me I needed one earlier too, but the ROMManager CWM didn't require it. It just screwed up my system files. So I popped one in and rebooted. Voila. Everything's kosher. If YOU have the same problem, make sure you've got an SD card in.
Ok, so now you're in recovery. You'll need to flash an OS of course. If you haven't already got it, get Tiamat 1.1 rom. Put it on the sd card. Wipe data/factory reset. Install zip from sd card. You're golden. At least I was. 5 hours later.
-Mike
Hey Mike I'm gonna give this a go. Just when i downloaded the img file to flash through fastboot i got an error saying battery was too lower to perform the recovery....damn it! The xoom isn't able to charge at the moment so i have to wait until it dies i guess (or i hope at least) and then charge it up and try again later.
Thanks again dude, hope i sort this out too. I'll download tiamat 1.1 in the meantime.
DUDE YOU'RE MY ****ING HERO!!!! I got it running can't say if everything is 100% just yet but the fac tthat im back in is enough to thank you so very much Mike!!! What a guy!
It worked? Great that's excellent news. Just out of curiosity - did you get there because you had ROMManager's ClockWorkMod? Or maybe you didn't do a full wipe before flashing a new rom? Or maybe you restored some WiFi settings with Titanium Backup after a new flash? How did you wind up with tthe problem in the first place - you know, for posterity.
well to be honest i am not 100% sure. I think the source of the problem msut have come from my previous installation of tiamat's 1.4.4 rom, it was always actin up on me and i don't believe i wiped the mod before i updated it and that may have done it. I wish i could give you more than just a pseudo answer.

Normally, I'd agree but in this rare case, he actually needed it to fully drain because he couldn't get it to power off using any normal method. Weird! so, it seems his only shot was to let it die to finally kill the screen and then start over. Very odd...

You are right...I had forgotten that from the OP. Very strange indeed.
Yeah I dunno why, my xoom was just acting up. It's fantastic now, albeit the wifi still has a couple kinks but android market issues have been resolved, i get much better streams and with tiamat 1.1 everything is already built in and with a quickboot option =)
Xda...where would i be without you!

You should be able to reboot the device using vol up + power, then holding vol down and vol up until it says "Cold booting Linux.....".
This should do the same as letting the battery drain, plugging it in and turning it on.
DeeJay - dunno if you've done this already, but if you haven't you should go back to the Tiamat 1.1 thread and find the Modpack. It fixes the Market update issue and gives you built-in screenshot capabilities and an option to reboot into recovery from the power off menu. It's in there - you just have to scroll down a bit before you find it.
Also - what issues are you having with WiFi?
Thanks for that important tidbit, solarnz. I'm going to file it away for future use.
OMG!!!! Dude you just saved my life! I thought my baby was out the window. I had the exact same problem as you did. I was trying everything from every thread that had anything to do with this problem. I just finished installing and it booted. WHEWWW!!!
Thank u thank u thank u!!
Glad it helped. I'm seeing all kinds of posts in here about the ROMManager CWM. Not good.

[Q] UK 3G Xoom - Possible brick? Bootloop after Moray update.

Never like to have to resort to posting myself but I've had a decent look around the web and can't seem to find a solid solution to my problem so I'm hoping to get some specific help
So I have a UK MZ601 3G Motorola Xoom which was happily running Moray 2.2.1 and had been rooted using the universal root method. Decided to update to 2.2.2 and now my Xoom is stuck in a boot-loop on the custom rippling water boot animation.
The tablet hangs on the first line when trying to boot into recovery so for all my efforts cannot access CWM and perform a hard reset and fresh rom install.
I've tried - and I'm assuming I'm correct in thinking this means I cannot get the Xoom to any stage where I can use adb to attempt to get in to recovery or push files to the system etc. this way.
From what I've read on other forum posts - booting holding volume up and power puts the device into an 'RSD' state which is another method of reflashing the device? I've read this requires an 'SBF' file - which I have seen for download - but believe it only works for the US models?
I've left the boot screen looping overnight - so its not an issue of it just being slow. Because of the custom boot screen I obviously can't return it to the shop as I presume its an obvious warranty void?
Would massively appreciate any help in bringing whats looking increasingly like a £500 paper weight back to life.
Thanks

When you press volume up and power, and hold it, it reboots, yeah? Then you wait about three seconds on dual core screen and tap volume down...what happens then? Do you see android recovery in upper left? Or starting fastboot protocol? Where does it hang? Just trying to see where things are going wrong. If you can get into starting fastboot protocol you are in good shape. If you can get into cwm recovery you should be in great shape. Check out the Xoom Heaven thread in General for some info on recovery.
You are most likely far from bricked...almost all of us have recovered from worse situations than you are in now so just keep cool.

Thanks for your reply - tried numerous times getting into recovery - get stuck with one line of 'starting fastboot protocol' and seems to hang there.
Have experience rooting and flash etc. and have obviously used adb in the past.
If I could just get to recovery - or a state where I could use adb I would be fine. But as I said in my first post - looks like I can only access an 'RSD' state.
Is there any other way of getting adb access from my PC? All the help for bricked xooms seems to concern US models - and don't want to try anything that will completely write it off!
Thanks again for your help.
Quick update -
Have retried Fastboot - stuck on 'Starting Fastboot protocol support'

If you are still rooted and all, just for safety's sake, make sure to do another nandroid backup and save it to your micro sdcard. Backup, backup, backup. Then also make sure that you have a compatible cwm recovery installed, that will let you access your microsd card. It sounds like you're alright, so, cool.

[Q] Boot Loop with no recovery mode

Ok so I'm new to the thread and basically to android tablets, so please forgive my ignorance if it should become prevalent.
I bought a Galaxy Note Pro 12.2 32GB wifi and had it for about one day. I performed a factory restore on the device in which it froze for about 2 hours. (this is probably the stupid part) I turned it off since it was not progressing after a long time and it booted up as a new device. After about 5 minutes of use, it randomly restarted and went into a boot loop. About every 15 or so boot screens, it sometimes boots up, then freezes and goes back into a boot loop. The longest it stayed active without resetting was about 10 minutes. After hours of research, I have done the following
Tried to boot into recovery to no avail. It just continuously pops up the device name screen
I have tried to flash the device with a stock rom in odin 3.9.
It recognizes the device but hangs at the Initialization stage. Sometimes it will give me a fail notice saying that it couldn't open the COM port
I've tried it on another computer, changed usb ports, powered on and off multiple times and nothing changes.
please let me know if i've forgotten anything. Any help will be appreciated.
Also I live in Japan, so if I can fix it myself that would be nice since this device isn't sold here yet, I'm not able to get support from a store. I'd like to avoid waiting a month sending it back to america, replacing it, and getting it sent back. Thanks in advance ^_^
Make sure you have the correct and latest Samsung drivers for your tablet.
If you have an SD card installed, try removing it and see if you can boot up and get it stable.

Wow, you rooted (void warranty) on a day old tablet on a platform that is new to you? I've been rooting Android devices for over 3 years now and have had mine for a week now without root. Don't get me wrong, I have a list of things I want that require root and it will be happening but I figured I should at least run it for a couple weeks to make sure no defects pop up before I void the warranty. Good luck to you!

If you have an SD card installed, try removing it and see if you can boot up and get it stable.

I've installed drivers a few times. No go.
I'm on it now and the boot loop seems to have stopped, but I still get random restarts. But each time it restarts, it's from factory, so it doesn't save anything I download or any settings such as enabling debugging in the developer settings.

Wow, you rooted (void warranty) on a day old tablet on a platform that is new to you? I've been rooting Android devices for over 3 years now and have had mine for a week now without root. Don't get me wrong, I have a list of things I want that require root and it will be happening but I figured I should at least run it for a couple weeks to make sure no defects pop up before I void the warranty. Good luck to you!

I didn't root, and I haven't voided my warranty. I can still get into download mode and my flash counter is still at 0. I never tried to root, I simply wanted to flash to stock, from stock.
[Edit] I'd also like to mention that Odin has not successfully done anything, Every time I tried to flash it was done with a stock ROM, and everything that has gone wrong has occurred on nothing but the stock ROM
Is it possible that I need a pit file for the device since no version of Odin will get past initialization? ....if so where can I get one for the this model?

If you are not rooted and you have a boot loop I'd be returning the device for a new one...

I hate to agree since you would have to wait for a while to get the replacement, however the device sounds to be defective. just my two cents as a developer, if you flash anything to the device, root, a new image, or even the factory software, Knox will be tripped and the counter will go from zero to a one. My advice would be to get a replacement for the defective one.
Developers don't need no stinkin' signature!

Huge 3rd.
Device should just plain WORK out of the box. There shouldn't have been a need to flash stock to begin with.
One last suggestion, factory reset from recovery. From complete power off, hold volume up+home button+power and after a few seconds let go until it boots into recovery. From there wipe cache, wipe davlik, and factory restore. Good luck!

Yeah, it's unfortunate, but I have to suck it up and just pay the shipping back to Ameica....then again for it to come back. Just wanted to do everything I could before I had to send it. Thanks for the input though. I guess I learned quite a bit researching processes and terminology which will be helpful in the future. ^-^

Tried many times. The device pretty much gives me the finger by going blank and repeatedly showing the boot up logo when I hold the buttons down.

I voided my warrant after having mine for about an hour (though not new to Android). I did all my random "OCD does it work as I expect/want" tests and it passed, so I rooted. Had it for one week now, and I absolutely love everything about this tablet.

IMO, it will be worth it. This is my fourth tablet, and is the first one I've not had buyer's remorse with. Luckily with the gift credit for Google I was able to get the non-Tegra equivalents of some of my favorite games, too.

After doing research, I think that even if I get a new one, I want to root it. With the problems I've read about for kitkat 4.4.2 I need to know how to fix problems, and start with a fresh install of roms and know how to use custom recovery. I haven't done anything yet, but I was wondering...
Since I'm stuck in a boot loop with no stock recovery, can I flash a custom recovery to fix my issues, flash the stock rom that is on sammobile.com and then root after that? From what I understand this is a soft brick since I can still sometimes access the device. I worked out why I couldn't access the device with adb and now it shows the device as listed. It stays on long enough to where I could flash a recovery before it restarts itself. I'm not trying to do anything stupid, just getting information before I pay the shipping for it back to the states. I've checked the knox counter in download mode, and it is still set to 0, so I haven't voided the warranty yet.
Any input would be greatly appreciated.
It's odd that a new device would not have recovery. I don't want to insult you, but just making sure we covered the basics, volume up+home+power gets you to recovery. The boot logo will flash about three times, make sure you're still pressing all three buttons, then let go after the 3rd flash of the boot logo then you should be in recovery. Volume down+home+power takes you to download mode, this is where you flash roms and recovery. I read in another post about someone not being able to get in recovery after numerous times, it turned out that he was hitting the volume down button instead of volume up. Just to be clear, if you do flash recovery, you will definitely trip knox, at this time there is no way around that.

I understand the skepticism. Yeah, I tried the button combination, usb in, usb out. I can power off the device completely only when it is plugged into power. When I hold the recovery combo from power on, the screen goes black with no flashing of the boot logo, looks as if it wants to go to recovery, and then then the boot logo comes up again, but just continues to the boot animation and continues the boot loop, even if i'm still holding down volume up and home buttons. It will sometimes boot up, then freeze after a couple of seconds, and return to boot loop. On rare occasions it will boot up, but turns me to setup like it's a brand new device. I can access everything for about 10 minutes, and then it will randomly restart and continue to boot loop again after that. I tried update/initialization in kies, but it would restart before the downloading and decompressing of binary could finish. It finished one time and then switch to a downloading screen (although it didn't say odin since you have to manually go there) but the update would freeze at 0 percent no matter how long I left the device there. It's all pretty lame ><

[Q] Android won't boot...

Hey folks...I'm running into a problem I was hoping someone might be able to help with.
Earlier today I pulled my phone out of my pocket at work and saw that it was off...I thought that the battery must have died sooner than I thought. I started charging it in the car on the way home and it wouldn't boot up like normal. It would get to the google or "dots" screen and then reboot. I again thought that the battery might just be really low. After getting home and charging the phone all the way I still can't get it to boot up. As of now, one of 3 things will happen...
1-The phone will turn on, get to the google screen and bootloop (usually when plugged in).
2-The phone will turn on, get to the google screen and freeze.
3-Get to the "dots" screen and either swirl forever or eventually reboot and do one of the above again.
I've read some threads where people suggest this is a faulty power button, that doesn't seem to be the case for me though because I can get into fastboot and it won't select anything or turn off without me doing it.
I've used WugFresh NRT and wiped/reflashed android. I'm running out of ideas. Do you have any others?
I was running the stock 5.0.1, unlocked, not currently rooted.
Thanks!

Did you try flashing factory images?

Yeah, that was what I flashed :/
If you can get into fastboot you "should" be able to flash stock images... Obviously this will revert any root and you will need to flash TWRP/CWM recovery after.
I assume you have a Windows PC with fastboot/adb setup and all drivers etc..
- Download latest "stock" hammerhead images (I cannot post links due to XDA rules... so: "developers.google.com/android/nexus/images#hammerhead"
- Extract the .tgz archive contents on your PC into a folder
- Boot the N5 into fastboot and plug USB cable from phone into your PC
- Go to the folder with the extracted files and run the "flash-all.bat" script on Windows
**Hopefully at this point your device will start to respond.. I.e, on fastboot screen, at the bottom you will see "writing" or something, as the script runs on the command window on your PC.**
If this works, you should be able to reboot once complete and then wait to see if you can get back into your phone.. then you can fastboot again and flash custom recovery, and then whatever rom.
If however you have a hardware issue (i.e, even after the above process it fails) then I am not sure what you could do... I guess ensure it has a complete charge. If you can get into fastboot and the buttons are responsive then it should not be a faulty power button.
Hope this helps :good:
Have you tried a simple factory reset? Reason I ask is it was working fine so sounds like something needs "flushing out" clear cache etc.

Did you choose the right model and firmware before you flash in WugFresh NRT?
The above could be right, however when I've used it, it's pointed out if I made that mistake. Having used his software dozens of times I've found it will bring any Nexus 5 back to life.

Hello! I am apologize for that I didn't read the OP carefully. This happened to me once in that particulary way, but it was immediately after flashing. OP says that it happened suddenly, without reason. So now I am the one, who doesn't read, right? Sorry for that.
Regards, Zagor
Thanks for the responses, but I'm still having trouble.
I have been able to successfully write the newest stock android 3 times (1 without full wipe, 2 with) and the phone still can't boot up and goes through one of the three issues above.
I've also been able to get to the system recovery from the bootloader and I've tried wiping the cache and doing a factory reset from there and the problem remains.
I'd contact google, but I bought it at launch so I don't think they'll do anything for me since it's been 1+ years.

Sounds like you have a bad nand sector. From fastboot try:
Code:
fastboot oem lock
Then reboot into fastboot and check if it's locked or not. If the device isn't locked your emmc is corrupt and there is nothing you can do. If that is the case call Google and they will most likely help you out with a RMA.

I was actually able to relock the phone.
Luckily I called google and they're going to send me a replacement.
If anyone else has any other ideas, I'll still take them...I'd rather not be without a phone for the next week!
You won't be without a phone - they are sending a refurbish unit to you , putting a block on your credit card and waiting for you phone to arive at them. Once that happens they will release the funds.
