[Q] Unable to factory reset

Yesterday my phone started acting up. All running process crashed and not many was able to start. I had to constantly click "force close". I think this started after I installed the Google+ app, but not sure.
I have tried uninstalling all unnecessary apps, without luck. I then tried wiping to factory settings by using the Android menu, but without any changing. I then tried by holding vol+ and power, going in to recovery and wiping both to factory and app cache. This doesn't change anything either. By googling I can see some suggests to hold vol- and power, to get to a another wiping-functionality but this just boots my Nexus S to normal state - no menu appears.
Has anybody an idea of what I can do?
Edit: more info; if I click "Report" and investigate the message sent to Google, I see that error has something to do with SQLite-relatet classes. Which makes some sense, alot of my changes are reset each time the phone is rebooted. For instance did I miss a call a couple of hours before the phone went crazy - this is shown at each boot in the notification area eventhough I clear the area and/or goes to missed call section

Factory reset via menu does delete all your "custom" apps, so I'd say it's not one of the existing apps causing problems.
The way you describe function after your factory reset sounds like factory reset didn't work properly.
If you feel safe I'd recommend rather flashing 2.3.4 again using either Odin or the OTA zip from Google (requires open bootloader).

I think you're right that factory reset doesn't do what is expected. Once I click it, the phone reboots and shows the Android guy next to an unwrapping package. This lasts only 2 seconds, then it reboots itself again and goes into normal phone mode (where all the app-crashing starts again).
I have not flashed or rooted my phone before, but I will consider this now since my NS is pretty much a brick. Thank you for your swiftly response.
Edit: Shouldn't I get a menu, when I push and hold vol- button, while turning on the device? Right now it just boot as normal.

Before you use odin....try going into rom manager a reflashing clockwork! Ive had that android dude on my screeen but reflashibg via rom manager always fixed it. Try that

Wow my Nexus has totally shut me out.
I cannot use ClockworkMod unfortunately since I am not able to root my phone. It is not detectable via USA (when I use vol+/pwr and connect USB). I am unable to check the USB Debugging option on the phone. Each time I check it, go to home-screen and back to the menu, it has de-selected it again. Also I noticed when I read the info that is sent to Google for all those app-crashes I get, I see SQLiteException and error in an SQLite.java file. So it seems like some database layer is broken.
I read one could copy the ClockWork.img to my phone and use the standard recovery option to flash the img (I think). But when I go into the recovery menu, the file is gone. When I boot the phone again, it has deleted the .img file - eventhough if I copy it to several different folders, they are all gone :-(.
I feel pretty screwed at the moment. How can I else wipe all data?

I'd recommend to check if your device is correctly identified in windows. Missing USB drivers might cause problems. Get the latest drivers and a guide from here.
If you succeed booting into fastboot properly (vol up and power) you can follow this guide. Get the latest cwm recovery.img here.
Last option would be to boot into download mode (vol up + vol down + power + plugging in usb cable) and use Odin from samfirmware.com
--
All options require correctly working USB drivers.

I managed to unlock the bootloader, by quickly turning on USB-debugging (before any processes started to crash) and install the drivers from this post:
http://forum.xda-developers.com/showpost.php?p=6819751&postcount=4
A reboot later, I got this message:
"System UIDs Inconsistent
UIDs on the system are inconsistent, you need to wipe your data partition or your device will be unstable."
Right below was a button saying "Im feeling lucky" (??)
I installed ClockworkMod using fastboot and tried "Fixing permissions" with no luck. I will try some ROM later on, and hope it will bring my phone back

Normally this error happens when you have a faulty app ruining your system, formating/deleting whole sdcard does usually fix this.

I can safely mount USB-storage and format the whole bunch?
I been sweating over this stupid issue all day now, all I want is a fac-reset :´(
Edit: "format /sdcard" using CWM didn't do anything

See I'm no expert on this whole thing. At this point I'd just flash a whole new system via Odin. Prolly not the smartest or safest option, but that's what I'd do because I don't know better. If that wouldn't fix it either, I'd return the phone on warranty

I was looking at Odin from the start, since nothing else seemed to be working.
So right now I got started on Odin. Followed the .pdf steps and flashed the bootloader at first succesfully. I was asked to remove the battery and re-connect my NS. Began downloading "pda" and "phone", but at around 10% a big fat red "fail" message appeared and now I just see the Google-logo on startup. I still cant flash any roms via fastboot.
Im too tired too right now, been working with this for 14 hours straight. I will look at it tomorrow evening. Thanks for your help rentaric

Weird, you're not the first one who had trouble running Odin using their guide.
Overall it's pretty simple.
Enter download mode. Vol up vol down and power at the same time while plugging in the USB cable. Start Odin, should show a yellow colored box with a port number. Uncheck everything but reset timer and auto reboot. Unzip the correct zip file from samfirmware.com (check if you got i9020 or i9023 and get the universal Odin exe), apply file from the folder accordingly. Bootloader and bootloader. Phone and modem. Pda and pda. Csc can remain empty (will change carrier info in fastboot).
Double check md5 hash to avoid broken files.

Of course I did not go to bed, how should I be able to sleep with a broken phone .
The firmware suggested on samfirmware.com for my phone, was 2.3.3 and some other version (my phone was 2.3.4.2/GRJ22 or something similar, I suspect that might be the cause. Also I unchecked everything, that might also have been of importance). The flash will always fail when everything was downloaded - it then said something about "remote" and "Loke" and then fail. But as I mentioned, I had succesfully flashed boot.img (2.3.3) thus no boot occured now. I googled the correct bootloader, used fastboot and was booting succesfully again.
I began looking more into the sdcard, as error-messages was leading me this way. To compress 4 hours of investigations into a few lines, it seems as my PBA is malfunctioning as other xda-members have experinced. Only solution is sending the phone to Samsung for a PBA replacement. I purchased the phone in Bestbuy USA and the danish Samsung partners are not too joyfull about this - I will contact Samsung and hope they can help me.
I experinced the exact same thing as this poor guy - http://forum.xda-developers.com/showthread.php?t=993403
Every thing you try to do to /sdcard is worthless.
Formatting (USB/using CWM/using adb shell linux commands) says "Succes" but nothing happens.
Copying files says "Succes" but nothing happens. If I boot phone into CWM, mount usb and upload new rom/apk/whatever and try to do a "install update.zip" it fails with some mounting errors.
Im ready to go cry in a corner - I really want this to be fixable via software, but I probably have to realize that this is a hardware issue.

Apparently Samsung doesn't offer worldwide warranty for cellularphones :´(. God it sucks to pay repair-expenses on a 1 month old mobile.

My G2x seems to be dead

I'm here, requesting help, i've read (i think) almost everything. Try everything and i'm not able to recover my G2x.
I'm from mexico, and my english it's no so good, i hope that everyone can understand what i'm trying to say U_U
I brought a used T-Mobile G2x from ebay. I was SOOO happy with the phone, a good one, a kickass and it was about $250 dlls for me. I think that was a good deal. The phone was on a average/good condition.
So, i rooted it, then after, moved the rom from stock to CM7 stable.
I changed then to eaglesblood ICS, then another eaglesblood, and then again CM7.
The phone was working very good. Then, a issue appeared.
Some day, the phone was a little slow, then i rebooted it. And then started the pain...
The screen showed the LG Logo, white brilliant. And after a seconds, power off. What!?
I tried to power on again. Nothing. I did the battery pull and then worked fine. I thought that was a simple bug or something.
Later, the phone ran out of energy. I pluged on the wall charger but nothing happened. I left it for an hour and tried to turn it on. Nothing...
Then charged the battery with a multicharger and the same problem. LG Logo, nothing. Checked on the CWM Recovery and did a cleanup of battery stats, nothing. I was desperate, so i've flashed my phone with Eaglesblood again. Vuala, the phone worked... 'till froze and i had to pull the battery... Again, LG Logo... nothing.
The phone boot up by himself after leaving it for an hour or more. But i had another problem... Battery at 999% Or battery stuck at 32% and suddenly dies...
I've checked with the battery app and saw that the battery said 0 mV
I have 2 batteries, and the both with the same problem. One LG, one chinese.
So, i went with a friend of mine, i took borrowed a battery of his LGO3D, and... nothing
The phone works with APX, powers on on the recovery, i even sometimes reads ok the battery and the phone comes alive, 'till i have to reboot it because the phone is so slow after 2 or 3 weeks without a reboot... but it's so rare and random...
I even updated the phone with the 21y baseband and the new stock rom, but keeps doing the same thing...
I'm just at the point that i want to throw the phone to the wall...
There are something that i can do?
Change some piece?
I must say that when the phone read the battery and it's ok, i can charge it normally, works perfectly, usb ok, everything it's like nothing was bad. But the problem is if the phone shut's down...

Get adb working with USB and if using a windows pc open Command Prompt and run
HTML:
adb devices
....Make sure your device is found, an ID number will appear if successful....
HTML:
adb reboot
....Let the phone start rebooting. When "adb devices" works and shows the phone ID again proceed...
HTML:
adb shell
$ su
# dmesg > /sdcard/dmesg.txt
# logcat -v time -d > /sdcard/logcat.txt
# exit
$ exit
adb pull /sdcard/logcat.txt %USERPROFILE%\Desktop\logcat.txt
adb pull /sdcard/dmesg.txt %USERPROFILE%\Desktop\dmesg.txt
exit
If you get a complaint with those last 2 commands; change %USERPROFILE% = whatever your username is where your Desktop is located. (i.e. C:\Users\me\Desktop\dmesg.txt)
Then either email them to me or post them on www.pastebin.com and post links to both files.

I'm a little lost...
First of All! Thanks for the help
And i dont know... The phone must be ON to do that?
The phone right now doesn't power on, just the LG Logo, at this point, when i attach to a computer via USB Cable, the computer doesn't detect anything...
I can enter the CWM Recovery, it's enough??
And a funny thing: The phone NEVER powers ON (Not even the LG LOGO) when usb or charger it's connected.
EDIT:
Good news, i've got adb working, but i don't have su, i'm downloading it thanks
EDIT AGAIN
The last time that i've flashed to stock rom the g2x forgot to root the phone
i've already tried with adb commands, but i got errors when i try...
I guess that i need usb debugging On, and i doesn't have it...
I'm on a dead end??

Go to the ROM for recovery thread in development section, follow it step by step and your phone will be 100% alive and kicking on GB 2.3.4.

If I recall you were the one who emailed me and I sent you links to NVFlash correct? Did that work for you? I'm just trying to see what your question really is. It sounded from you OP that the hardware perhaps keeps failing and no matter which ROM you flash, you eventually get stuck in bootloop like you are now. Are you just trying to get out of bootloop or is this a reocurring problem? If your stuck in bootloop then your only solution is to NVFlash a recovery and push a rom. If its reocurring then we gotta figure out why... thats where my instructions come in. So you need to tell us exactly what you're trying to do.
As for adb yes you can adb from recovery. You gotta go to Mounts and storage > Mount /system though or else the device wont show.

Ok... my first problem: Language. I don't have problem with the reading, but writing... i'll try to put my words on the right place
I don't remember, when i first flashed my G2x i did it with the Rom Manager App... the result came on a bootloop. Then i used NVFlash and flashed a correct ClockworkMod Recovery. Installed CM7 and everything was fine. Then i wanted to try ICS and flashed it again. No problem. I normally follow the guides step by step, and the phone was right. Then, one day the phone froze and was the first time that i had the bootloop with the LG Bright Logo, then dim, and then power off.
The problem not was while i was flashing a rom. Because while i was on the problem, i flashed with NVFlash the original bootloader and then restore the original firmware, and the problem still there. Right now the phone has the stock rom, updated by the LG utility, and the problem persists.
I think that is what you say. The phone doesn't pass the LG Logo screen no matter which rom i flash... What i don't understand is that the phone seems to be ok. When it powers (a week ago) it worked just fine...
I don't think that is a bootloop caused by a bad flashing... i think that is a recurring problem...
I have this 2 folders with tools for the NVFlash, i think that the both of them are right...
One-Click-G2x-recovery-flasher-04-28-12 [Folder]
One-Click-G2x-recovery-flasher-09-23 [Folder]
They have the APX drivers and NVFlash and the One-click-G2xr-recovery-flasher app...
I'll mount the /system in recovery and i will try to get that log. With the /system mounted then i think that i can root the phone...
I'm gonna try... let's see what happen...
Thanks
EDIT: I noticed (when the problem first came) that the sticker of water damage was ripped off... is not there... But i don't know if the phone was really damaged by water, because i'm not the first owner... The phone was working fine for about 6 months and now it's just like i'm explaining...

Ok, I bet your partition tables are messed up. If you can get that dmesg and logcat file it would be ideal but if you cant then we just gotta move forward.
First copy all your stuff from SDcard and internal memory into a folder on a PC. Make a backup using clockwork or whatever and also copy that onto a PC just to be safe.
Then you need to search the G2x forum for this batch utility called something like "auto-formatter partition repair tool" or something similar. If you cant find it message me.
Youll want to run that first, its going to completely wipe all of your stuff and reformat the blocks sizes. Once done youll need to NVFlash a CWM recovery again. Then push a ROM over to the phone and install with CWM. (Dont push a stock rom or anything Gingerbread. Ideally push EaglesBlood ICS since I know it works and can help you troubleshoot.
So i would do that first because i bet your upgrade when u said you attempted to install ICS corrupted the file system, which can happen if you dont format /system prior.
Get the utility, backup everything , format the partitions, NVflash CWM recovery, push ICS rom, install, install GAPPS, come back here and tell me it worked

I think thats the right one, or at least, one of many...
That utility flashes a CWM Touch, then, i installed Eaglesblood Gingerbread (because the utility said that if i don't, the sdcard will not be recognized) and the gaaps...
Turned off the phone...
Turned On...
But then again, i have the LG logo bright, then dim, then power off :/
Do you think that could be a charger flex problem? Motherboard? I should burn it?? :/

Use the batch cleanup tool, then flash stock rooted ROM. That way you cab make sure something works, and stock is going to be the safest flash. If that works, then you can go on to custom Roms

Yes thats the utility, and the post above by "rtotheichie" is correct too.
You cant flash a Gingerbread ROM. You need to either push a stock/rooted build, or an ICS build. It's that gingerbread -to- ICS thats causing the partition problem (if it even is that). So what you're doing is fixing it then messing it up again.
--> There could be any number of things going on and we can guess at anything but what good is that gonna do? ... You NEED to get that #dmesg log. I would focus on doing whatever you can to get ADB working because thats going to tell us exactly what is failing at boot time. Can you get into Recovery? I wouldn't even worry about starting the ROM, you should focus on getting into Recovery first. If you cant get into Recovery then you didn't flash it correctly with NVFlash. If you can get in, then go to Mounts & Storage > mount /system ...then get that ADB going using my 1st post above. Thats your only hope if you cant get it on your own.

No problem.
Well if you can get into recovery and if you have ADB and the drivers for the phone setup on your PC you should have no problems connecting. Try using a Windows PC if you can, it's funny but ADB is probably the only thing that is easier to get going the 1st time in Windows rather than Linux (Ubuntu).
Just keep trying and run
HTML:
$ adb devices
each time until a device ID shows up.
I've noticed you've posted this same question on like every single Android website that exists; but I'm telling you what the correct answer is and the only way you're going to be able to figure out what is going on is to get to a log file. No one has a magic trick that will automagically fix this from afar. Anything else is just guessing and checking.
In recovery, try going to Advanced > Show log ...what does that say? Also it won't hurt to try going to Advanced > Fix permissions. I doubt that will do anything for you but it won't hurt to try at this point.

And another thing. I've checked my PM's, and saw that i've never send a PM to you. And no, i'm not flooding the entire www with my question. But i think that i should have used a diferent question to describe my problem. This is the first time that i ask for help, after reading and reading on the web, and almost everyone says: "send it back to t-mobile", but that's not an option for me. And my first choice (and olny) for asking help of course it's xda.
I remember that once clicked "show log" and an error pop out, but i didn't try the fix permissions options.
This is the video. Sorry for my bad english.

I saw the video.
Take out the battery > then put it back in.
Press and hold BOTH the [Power] and [Volume Down-] at the same time and keep holding them.
Keep them both pressed while the "LG logo" appears; shortly after you should see the white logo change to a BLUE logo... once you see that you can let go.
Does that work and get you into Recovery? ...let me know.
One other thing to try...
Plug your USB cable into the Computer ONLY ---Not the phone.
Take out the battery, do NOT put it back in.
Now (with the battery still removed), Press and Hold [Volume Up+] and [Volume Down-] together. Do not press the Power button.
While still holding both Volume buttons together, insert the USB cable into the phone.
Now wait a second or two, does the phone Power On into a "Download mode screen"?
If not, let go of the Volume buttons and unplug the USB from the phone.
Now plug the USB back into the phone. Press and hold the [POWER] Button for several seconds (still with NO battery in, just the USB).
Does that turn the phone on?
P.S. - This might be good to have as well:

Now (with the battery still removed), Press and Hold [Volume Up+] and [Volume Down-] together. Do not press the Power button.
While still holding both Volume buttons together, insert the USB cable into the phone.
Now wait a second or two, does the phone Power On into a "Download mode screen"?
If not, let go of the Volume buttons and unplug the USB from the phone.
Now plug the USB back into the phone. Press and hold the [POWER] Button for several seconds (still with NO battery in, just the USB).
Does that turn the phone on?
P.S. - This might be good to have as well:

Ok, i tried the first thing. The phone gets on recovery mode. All good.
On the second thing to try:
-I followed the steps just as you said: vol+ and vol- and connect usb cable. It makes a sound of connected device, checked and windows detects a NVIDIA USB Boot-recovery driver for Mobile devices, but the phone screen never powers up or show a download mode screen. When i flash anything with NVFlash it shows the Download mode screen...
-I plugged the phone without battery, and pushed the power button. The phone does not power on. Not even the LG logo or anything.
I'm still trying to get that logcat. But everytime that i want to type "su" on the adb shell says that cannot found su...
Now i'm on recovery.

Whats the status on this are you still dead? Looks like you need to do that partition formatter script now... appears your partitions are messed up. What ROM is on there now?

Sorry, i didn't get the mail of new post...
Yeah, it's still dead...
Today, i put the battery on the phone and it started right away. Battery status ok, everything working fine. But i didn't put a sim card, so i turned off the phone and it's dead again.
I don't know if i'm getting a GOOD partition formatter. But i've already used one... and the result it's the same...
And even tried a crazy method of one guy that put the phone on the fridge for 10 mins and then NVFlashed-it to a stock gb...
And nothing U_U
Power up, show a bright LG logo, then a less bright one... power off...
Thanks for your help...
EDIT:
Today i opened the phone, extracted the logic board and watched everything. A VERY SMALL bga chip (i don´t know wich) had a little crack on it, i cleaned with a soft brush and a little piece came off... Now the phone doesn't boot at all, not even the LG logo... i think that's the end...
If someone can indicate me where i can buy a new mainboard it would be very appreciated. Thanks.

lg mytouch c800 bricked?

hi im pretty new here a friend of mine gave me her lg c800 mytouch to try and fix it for her.. not sure what she did she said she rooted the phone and the root was successful but i have a good idea that she doesnt know what she was doing..i will post a pic of the error screen im getting. but it says
E:Cant find misc
E:cant find misc
Finding update package...
E:unknown volume for path [sd:/download/adb_fastboot_and_other_tools.Zip]
E:Cant mount SDCARD:/download/adb_fastboot_and_other_tools.zip
Installation aborted
facory reset failed
restart factory reset..
now im far from a pro at this i know a lil more about computers and Ios devices..but ive rooted a few phones and to me it looks like she unzipped adb fastboot on her phone from her sd card??
ive tried holding F..A..vol down..and power..Nothing..
ive tried volume up .volume down and power still nothing..
BUT if i hold E..vol UP and power it brings me to a white screen that says S/W update
the big problem is the phone wont stay on long enough to do anything on the computer it stays on 3 sec. then reboots to same screen (computer says phone is unplugged) then phone just keeps restarting.
but the phone WILL stay on when i put it on the S/W update screen..but computer wont recognize the phone at all on that screen
ive tried the adb and fastboot commands but the phone wont stay recognized..it will recognize the phone and say thats its in recovery mode but when phone restarts it dont see phone no more..
well thanks ahead of time if anyone has any input or solution
and hopefully all this will make sense to someone lol
i think this pic will work.. if not ill try again

any ideas please?? or am i completely out of luck?

...do you mean that you can successfully communicate with the phone over USB, but you only have 3 seconds? What way is the phone recognized? Is it visible to adb/fastboot?

Yes In Adb device list it shows the phone and then says recovery..but after that I don't have enough time to type any other commands ..the phone is also recognized in "my computer" as removable device then when the phone restarts seconds later it says device unplugged ..and just keeps restarting on its own till I remove the battery...I just read on the forum in a post that Adb will recognize the phone if it's off but I remove the battery and put it back in and plug in USB and phone turns on and keeps restarting won't even let me turn it off!! I'm losing patience with this thing lol
But I don't get why the error mentions fastboot? Not my phone so if it's not fixable I don't really care but I'm just the stuborn type when it comes to fixing electronics ..again thanks ahead of time to anyone that helps cuz I'm completely lost on this one

Have you tried timing it to send a quick "adb reboot recovery"? If you can use fastboot, you can tell it to boot off a new, custom recovery img, without actually flashing it.

i have the same problem

i used an app on the market to remove bloatware. i removed slacker and the app stated that after two reboots that everything would be fine and the app would be gone. after one reboot the phone has the same screen this gentlemans lady friend has. it looks like the app its looking for is no longer zip aligned properly. someone told me to rename a recovery image the error message to trick the bootloader into thinking the missing app is there. hes an app dev so i figured he knows whats what. ive tried everything the gentleman in this post said and more. hell i have two of these phones and rooted the other and made a backup of that phone and dragged the backup to an sd card and rebooted to see if any of the backed up system apks would trigger a successful reboot but to no avail. i have all the drivers i need and adb commands but nothing works because the phone doesnt stay connected to my pc long enough for anything. please reply with some knowledge. ive been scouring the web for at least a month. i was so happy when i came across this. i actually became a member just to post about this erroer (look up diabolus ae in the forum search field. my post is about 3 days old with a better pic of the screen message. i bought a galaxy s II but i want to give the lg to my son. please help or respond:cyclops:

Normally, if you want to flash a custom recovery through fastboot, people will tell you to run 2 commands:
fastboot flash recovery nameofimagefile.img
fastboot reboot recovery
Since you don't have time to execute those 2 commands, you can tell it to just boot from the .img file, without flashing over your current recovery. (This is actually proper form, as you can test if the .img file works properly without damaging your existing recovery.) The way you do that is to 1st copy a recovery .img file to the root of your SD card, then execute the following 1 command:
fastboot boot nameofimagefile.img
Since you only have ~3 seconds, type the command in, and wait for the right instant to hit enter on the keyboard. If the command is successfully sent to the phone, it will reboot into that .img.
See if that works for you. Good luck.

help- bricked it, no recovery, what now?

Hey yall. I had the phone for 6 days before I bricked it. I am wondering if there is any stock recovery mode or anything or what I shsould do? I think something went wrong due to using the root toolbox pro app. I have done some backups within the ap as well as Titanium Backup but now the phone will not boot up and I dont know if/how to put it in factory recovery mode. Soft reset does nothing. The Motorola logo will show on startup but then the screen just blacks out forever, not off, just colored black.
A few details, the phone was rooted with Motofail2go, with no recovery and bootloader still locked as far as I know.
Should I take it to Sprint for a factory reset? Is this even an option? What are my other options?
Next time I will probably use the Moto unlock key so I can open the bootloader all legit like and have a recovery mode...

Try holding power button and the down volume key to power off. Once you power off press and hold them again. This should boot you into fastboot, Motorola's adb shell basically. This can take a couple tries, make sure the phone is powered down completely before hitting volume down and power button to get into fastboot. If you can boot into fastboot you can unlock using this guide: http://www.droid-life.com/2012/08/20/how-to-unlock-the-motorola-photon-q-bootloader/
Once unlocked flash the custom recovery of your choice (I like twrp). You can boot into custom recovery by holding volume up and the power button from a powered down state. Here is the link for instructions on how to flash twrp:
http://forum.xda-developers.com/showthread.php?t=1887070
Then you can download one of the stock backups for the Q posted in the development section and restore them using the custom recovery. Most of the ones I have seen have been compatible with twrp.
The only way to download the stock rom backups is to remove the sd card from your phone, plug your sd card into a PC or other device with a card reader, download the stock backups, and place the stock backup rom files on your sd card. Finally place the sd card with the stock backup downloads into your phone.
These backups and information on how to go through this process can be found in this thread on page 2: http://forum.xda-developers.com/showthread.php?t=2001226
The key is to make a backup of your existing rom with twrp and then move the stock backups from your sd card to the twrp/backups/yourdeiceserial/ directory. That creates a backup directory which twrp knows to look for backups in.
Don't feel bad, I've been in that state several times since getting the Q, live and learn.

If that does not work you could drop it in water or something. You have not officially unlocked boot loader so you still have warranty. Or you could just tell sprint it quit working and act completely clueless. At least its bricked with warranty still intact.

Both of the methods above are very effective. When I had the first photon I bricked it and just dropped it in water and did a claim. Depending on the insurance you have that way may cost you $100. The other method should work. When I first got this phone I did the exact same thing and to go back and unlock then flash twrp and in stall a stock backup someone had posted.

Thanks for the response. Is there anything extra extra special about getting into factory fastboot mode? I can't seem to get it done. Is there an official set of instructions anywhere? Does the phone need to be plugged into the PC? It was always my understanding (for the last week) that Power and Vol Down was the soft reset mode which reboots the phone. Therefore it always tries to reboot in normal mode. This is what keeps happening. It never powers completely down using this method.
Anyhow, once I follow your instructions, the Moto logo appears, no Sprint logo appears, the phone "powers on" but the screen is blacked out (not off). After waiting for a while at the blank/black screen, or holding down several buttons like vol or camera I get the first attachment: "Process system is not responding. Would you like to close it?" When I wait nothing happens. When I push OK nothing happens. By chance, I held down power during the notification and the power menu came up behind the ANR notice (second/third attachments). So obviously there are some things working but the main system isn't booting up. And either factory fastboot is nuked or I can't figure it out. When I power down from this accessible power menu and try to do the fastboot (Power / Vol Down) I still havent gotten it to work.
Any other ideas before I take drastic measures?
Since I bought it from Amazon would that be my best route for return or should I go thru a Sprint store?
Thanks in advance.

Hi again yall. You know once I got to thinking about it, I decided to check out the return policy on Amazon Wireless. They will accept any device under warranty for the first 30 days and it is up to Moto for the next 11 months of warranty coverage. They email me a packing label and it ships out 1 day and they ship out the new phone 1 day shipping. Hard to beat, just takes 2 days of shipping and some more fun times with my Epic, 10.1CM style, in the meantime.
Who's to say it wasnt some sort of hardware or software glitch that bricked the phone rather than my screwing around? Nobody knows and it isn't up to the consumer to prove his innocence. I bought everything legally, all the apps at the app store, and only ran the motofail2go root method. Wasn't running any custom Roms, Mods, or anything. I don't feel bad after they got me for another 2 grand for 24 months, and since I have been with Sprint for 10 years;l I have spent well over 10k or 15k with them lifetime.
If any other method pops up between now and when I ship it out I may give it a shot but if not, ah well, capitalism.

Try using adb. If your computer has drivers on it for phone you might able to get into fast boot. If that does not work I would try Sprint store first. Have locked my phone up several times while hacking wife off in progress and have used adb every time. Only time i have been truely scared is when i soft bricked my nexus 7. had to stay at work for two hours after i got off to get it to recover because i was scared of her lol.
---------- Post added at 02:05 PM ---------- Previous post was at 01:57 PM ----------
If you get adb to recognize device you could take chance and officially unlock boot loader. Then flash twrp. There is a thread in general section about having trouble getting official update. It has a stock recovery in it. Trick would be moving files to recovery section of twrp

I have gotten the phone to soft power down and get into fast boot and custom recovery. It's a bit tricky with timing, I usually wait for the screen to go black after soft reset, let go, and immediately hold power and volume down. If you can not boot into fastboot I honestly don't know what you can do either than return the phone.

Thanks for the help Unicron. I think Brandons method might be my only alternative... but you know what? I already have the box packed up to ship back to Amazon! I am still a noob; I dunno if I could go the distance on this one. I have been updating my Android SDK files since I got the phone but I never got it to recognize boot up thru ADB fastboot. disclaimer* I havent tried it in a couple days since all teh SDK updates completed.
I dunno though I am a big time DIYer when possible. If it werent for the massive amount of tape I put on the box and packing label I would already be trying this method. I can't convince myself just yet. Amazon makes it too easy. I could have the *new* phone by Friday. Then I wouldn't be wasting my remaining work week trying to hack into my personal Christmas present in order to make it function...........................................
Edit - Yes I'm impatient. My job is too demanding and I am trying to set a good precedent for 2013. Wasting the first 3 work days on a phone is not how I intend to start off the year. There is probably a valuable lesson to be learned from this as far as hacking experience and to be honest with the responses here I think I could get it to boot up from PC in SDK/ADB mode and go from there. I just didnt know if that was possible until after I made the claim with Amazon. I still have an entire day today and tomorrow if I want to indulge myself. It doesnt matter if I mail the package today or Wednesday, I can still get it by Friday. I believe this thread is still valuable because we have patterns of repeating past failures and I may find use of it when I recieve my new phone and, darn it, it mysteriously bricks as well. in the same fashion.... the only thing I was really trying to do was get all my apps on my SD card... sad huh?
Edit 2 - Opened up the box, tried fastboot and adb, nothing. Off she goes.

I don't blame you, it sounds easier to exchange in your case any way. The main suggestion I have is if you are getting into any type of build.prop or operating system tweaks that have potential to lead to boot loops or cause the phone not to boot, then unlock the bootloader and install custom recovery.
The Moto-fail method seems limited to only be able to run apps that require root. For me this has no use as I want to be able to have complete control over all aspects of the Android OS. There is not a huge mod community for the Q as yet but I believe Cyanogen will be a reality as Interloper continues working on it. I came from an Epic with Cyanogen and soft-bricked it a minimum of 50 times. CWM was very forgiving on that phone, the Q is a lot more finicky and frustrating.
If you have insurance through the carrier then you are going to pay $150 for a refurb if something goes wrong and you hard brick the phone. If you unlock bootloader and install custom recovery then you have a fail-safe in the form of nandroid backups and restores. Then you can mod away with little fear.
Good luck on the new phone and I hope you don't give up after six days of modding with the Q!

FWIW, pressing vol down + power til it resets then pressing the camera button + power once the screen is black gets you to the Boot Mode Selection Menu, where you can start recovery, fastboot, BP tools (still not sure what that is entirely) and some others. Seems to be a fairly reliable/easy method for getting to both recovery and fastboot from any point.

It does work without any recovery mode and I believe it still works without the bootloader being unlocked, I didn't know about this myself until after I had already unlocked it. Sorry I couldn't help out sooner.

Awesome, I am wanting to do the backdoor root method again but, of course, may brick it. I dont think Amazon will keep sending me new ones.... but maybe!

For anyone concerned, I knew it would only be a matter of time until bricking my new device. This damn Root Toolbox Pro did it to me again, and on a simple, menial task. I am going to be working thru the motions on getting this to work.
Using the instructions quoted I did get stock recovery to work or at least flash on the screen for a split second. Seems like there is a timer on the recovery screen. I am having trouble with the fastboot prompt though on the PC. Do I do it in the "platform-tools" folder which contains fastboot or in the "tools" folder of the main SDK directory? I am really a noob, can you give me the cliff notes of how to get into ADB, fastboot, etc on the Photon Q in order to do a factory reset? I already have Android SDK installed and completely up to date so that is done. And Fastboot is installed. I'm just having trouble crossing the finish line here... I can get the fastboot page opened in the stock recovery but from there I'm lost. I dont know what to type into the command prompt, in what directory, or what.... Also when I open the command prompt in the SDK folder on the PC with fastboot in the directory and type "adb reboot bootloader" it says "device not found". Maybe (surely) that is the wrong prompt?
FWIW my phone is showing the dead android guy. I didnt do anything besides try and clear up my Play Store download list which required a reboot. The phone never started back up. I dont know how much damage was done or info was lost or whatever, but seeing as how I was rooted but still locked, I had no custom recovery. So no back ups. Is there anything to restore or am I looking at a full wipe and restore?

I dont know how much damage was done or info was lost or whatever, but seeing as how I was rooted but still locked, I had no custom recovery. So no back ups. Is there anything to restore or am I looking at a full wipe and restore?

As abnormal as it seems, your situation seems pretty normal... at least from my shoes. I went through the same scenario... I didn't know what adb was, or fastboot, etc. So, here's what I know
the fastboot commands work even if adb doesnt see it in the list of devices attached. Somehow it just works (as long as the phone is in fastboot mode).
If you're able to get to the fastboot mode, things should be okay. Just open a windows explorer window to the Platform-Tools, hold the shift key and right click on a blank space within the window, then click open command window here.
you should be able to pass any adb (if the phone is on and recognized) or fastboot (if phone is in fastboot mode) commands from that command prompt.
Also, if you have a stock recovery, CMW, or TWRP image, this is the folder to copy those .img files to. Once you get your phone into fastboot mode and its plugged into the computer, just type into the command prompt:
Code:
fastboot flash recovery recovery.img
If you're just looking to reboot the phone into recovery
If you have a CWM or TWRP recovery just replace the recovery.img with whatever the .img file that you have. Also, as a tip instead of writing the entire file name, just press the first couple letters then press the tab key within the command prompt, it should fill in the rest. keep pressing tab until you get to the .img file name you want.
To avoid doing this again, maybe I can help... what were you trying to do to begin with? From the sound of it, you were trying to root the phone with the Root Toolbox Pro but it bricked, and then you tried to reboot into recovery and then got the red android... ?

Thanks for the response. So, all I have to do is: go to fastboot and flash a stock recovery image file and it will automatically wipe the phone, cache, everything, and restore the operating system? Sounds awfully easy! I found some stock files in this post : http://forum.xda-developers.com/showthread.php?t=2001226&page=2 Are these the ones you used before?
Last question: I can flash CWM or TWRP but wont be able to access them if my bootloader is locked, correct? So flashing a stock recovery will allow me to have my stock phone back again, locked and un-rooted? I guess if I cant get it to work with the stock recovery then I can unlock the bootloader and do a CWM or TWRP recovery and then flash the stock .img files?
Thanks again for your help. I already had root with the motofail2go method which I like using but seems like when I try and use some generic root feature from apps from the app store that it will crash/brick the phone cuz obviously those apps are generalized and likely to brick certain percentage of devices....

Ok what does this mean? Something with the bootlaoder obviously. Does it need to be unlocked?
Code:
C:\Program Files (x86)\Android\android-sdk\platform-tools>fastboot flash recover
y qrecovery1.img
(bootloader) Variable not supported!
target reported max download size of 31457280 bytes
sending 'recovery' (5962 KB)...
OKAY [ 0.479s]
writing 'recovery'...
(bootloader) Preflash validation failed
FAILED (remote failure)
finished. total time: 0.755s
C:\Program Files (x86)\Android\android-sdk\platform-tools>
And on the phone screen it says "invalid image size for partition recovery" twice for both times I tried this method.

You will need to flash the system image as well if you want those, as the recovery image will only flash the recovery. The files in that link are for twrp only... so you'll have to be able to get there first.
With the custom recoveries, I'm not 100% sure whether or not you will be able to use them without being unlocked. I would wait to see if anyone else can answer that question for you, but if you did try it without an unlocked bootloader, you at least have the stock recovery to fall back on if needed.

I'm thinking it could either be that your phone is full and the image you're flashing is too large to fit on the space available...
Or you're trying to flash custom software on a locked phone.
Hopefully someone is able to answer that a little better...

You can't alter the stock recovery (flash a custom recovery like twrp or cwm) in fastboot without having the bootloader unlocked. Your options are to unlock your bootloader, flash custom recovery, create a backup of your current setup, download one of the stock working backups, place it in the backups folder for twrp on your external sd card, and restore one of the known working backups in the development section (befrosty linked to one). Or you could use RSD lite to return to stock using a stock factory firmware flash. That involves connecting your phone to your PC and flashing the phone back to factory stock. Information on RSD Lite and links to the FXZ's can be found here.

Pro tip: Don't bumb old threads like this. You might not even have similar problems. Instead create a new thread regdaring your issue.
Now, post your tablet info HERE:
Root staus?
Can you boot in recovery? If yes what recovery do you have?

Root Status = ROOTED
I cannot boot into recovery mode (but when i try i get this, look in pic 2&3)
Tablet Type = HKC (NOT HTC) p776a
ANDROID Version I think (98% shure) is 4.1.1 beta JB
What happened = A few years ago 2013 i think a got this tablet then i learned about rooting, roms, and such so i spent the next year or two trying to root the tablet. I finally got it rooted with a chinese root program and all was well (i don't remember the name of the program) then there was a update for su and i pressed the twrp/cwm mode on accident (I think I was talking to someone at the time) and now it does what is shown in the image 1 it is on some boot loop. When I try to access the hboot menu it does what is shown in these images 2&3. Also my tablet has a MicroSD card slot and the battery can not be taken out. the regular bootloop picture is image file 1 that is what it looks like when it does its continuous bootloop and P.S. the tablet turns off and on automatically during the bootloop. To try and fix it i have let it do its bootloop for hours on end turn it on and off tried looking for a compatible rom (to no avail) and let the battery completely die that is about it.

Okay. Just a few more questions.
Does your tablet boot into recovery (picture 1) even if you try to boot normally? (fastboot maybe)
Can you boot into anything else other than recovery? (try different button combinations)
Does ADB recognise your tablet when it's in recovery mode? (if you don't know about this, just post your computer OS and if you have ADB/Fastboot drivers installed on your PC)
If the anwser the the first question is no:
Does ADB recognise the device while it's in the bootloop.

sorry, i forgot to clarify the hboot. it pops up the "words" or whatever then automatically reboots there is no way to select options or keep the device on so i cant use fastboot unless there is a way i dont know of. P.S. the tablet restarts automatically so it is on for like 25 maybe 30 seconds then shuts off then turns back on and repeats till the battery is dead. My thought originally to fix it was to get a rom put it on the sdcard and see if that works but the manufacture does not supply the rom for my model only the p771a. and the only physical buttons are the home, power, the pinhole reset button, the volume and such buttons are virtual on the screen when it is fully on. And picture 1 i dont fully know what that screen symbol is the hboot one is similar but not that but yes it does but to picture 1 nomadder what i do even if i try to get to hboot menu. Sorry if this is a "little" scattered having explaining it. If it would help i can make a video and rar it and upload it here.

1. Download fixcache.bat.zip on your computer. Extract cachefix.bat from the file.
2. Run it. It should say just "Waiting for device..."
3. Now reset your tablet with the reset button and QUICKLY plug it into the computer and wait a few minutes.
Now try to get to that text in picture 1 and tell me what happends.
Also post the text you see on the computer from the file I sent you.
Tell me if

Umm, you said there is a reset button on the tablet so pressing that would probably reset it.
The error you are getting is because adb is not installed on your PC. Use this simple adb installer to instal adb. When installing just press yes to everything. MAKE SURE THE PHONE IS PLUGGED IN THE COMPUTER WHILE INSTALLING AND THAT IT'S ON!
Now run the file again.

If you want to know what is happening:
You are in what's called a recovery bootloop. It's when you can't get out of the recovery. What is happening in this case is that Superuser app tried to install it's binaries via recovery. Because some people don't know how to install binaries manually, the app puts a file on the cache partition so the recovery automaticly installs the zip upon booting. Now, this would be good so you don't mess up your device, but the zip file it's trying to install is faulty so it just breaks the device.
My attept at fixing this is to delete the /cache/recovery folder so it doesn't just install the file, and instead boots into a working recovery.

That would be great but i cant keep my tablet on for more than like 30 seconds before it auto shuts off and it automatically tries to go into recovery when i add power to the device it wont just boot to the OS

30 seconds is more than enough. Especally with an automated script like the one I sent you.
The first thing we have to do to fix your tablet is to establish a working ADB connection. Use the ADB installer i sent you. And look up on how to install Google USB driver for ADB.
