[Q] Question about reset switch

Hey, all.
What does the internal reset button actually do? I was expecting it to reset to factory settings, but fortunately for me it didn't do this. I'm actually happy it didn't, as it means I didn't lose any of the customizations I had done or applications I had installed.
I just cracked open the case on my gTablet and pressed what I assumed to be the reset button, a tiny little white switch in the center of the unit. After pressing and holding it for about 3 seconds, the tablet immediately powered back on and returned to its previous state. Everything appears to be functioning perfectly normally and exactly as it was before.
What does the reset button actually do? Do I need to worry about battery meter not being accurate or any other weird side effects? I only mention that because the battery gauge is showing 100%, but the external red charge light is still on.
I'm not sure what prompted it, but earlier today, my gTablet went blank and wouldn't turn back on at all. My son had been playing Angry Birds for an hour or so and I had been using it heavily showing it off to my in-laws, so I thought perhaps the battery had simply gone dead. I had not plugged in the charger the night before, so it seemed to be a reasonable explanation.
I plugged the charger in and the external red light was visible, so I let it charge for a little while, then tried turning back on. I could press any number of different key combinations (power & vol+, power & vol-, holding button for long time followed by short press, etc.) but I got nothing but a black screen. There was no indication whatsoever that anything was happening.
I was assuming something had gone quite awry, but didn't panic. My wife was not quite so calm, but I reassured her that I would be able to find the answer on the XDA forums. Thanks to everyone who has contributed to this great community, by the way!
First, I tried plugging in the USB cable to my Windows 7 laptop and heard the distinctive 'bing-bing,' notifying me that hardware was recognized, so I knew it wasn't dead. But, it didn't show up anywhere, so I checked the Device Manager. Interestingly, there was no yellow exclamation mark anywhere, as I expected from reading some other posts about NVFlash. I finally found it listed under the 'Disk Drives' section as: 'NVIDIA Tegra 2 USB Device.'
I remembered reading about people experiencing problems with the unit going into APX mode, but I also remembered reading about the internal reset button on the gTablet. So, I figured before I attempted to use NVFlash, I would try the reset button first. Fortunately, these devices were designed well and the case was very easy to pop off.
By the way, I was running the stock ROM, but with the TNT 3588 Enhancement Pack (Gapps with nVidia Drivers) provided by edirector. I had also installed the z4root application. I used the default ROM for the first day, but was comfortable with the idea of flashing othe ROMs, as I've done it with my HTC Aria phone. I flashed roebeet's TNT Lite 4.40 and used that for several days before going back to the factory ROM with the enhancement pack.
Thanks in advance,
Calvin

Well,
I've been reading these forums since last November and I don't know of anyone who
has really reported on "pushing" the reset button before!!!
Usually when people crack the case to push the reset button or unplug the battery
for 10-15 seconds it is a situation where they can't get the machine to start and
literally have nothing to loose.
Sounds to me (in terms of 30+ year of different computers) that you did a hardware
reset and boot. I assume something was locked up inside and the reset key released
it to restart.
Glad for you!!!

[Q] Nexus S i9020A Bricked due to failing power button - Odin seems the last hope?

Hi everyone,
INTRO:
So the power button on my Nexus S broke. No big deal, I remapped it to the search button and used the volume rocker to wake the device; an option that was embedded in Cyanogenmod9.
Then I upgraded to CM10... since I did that on top of CM9, my volume rocker option was still enabled, but the option is no longer in CM10's GUI.
I had some annoying issue and thought maybe I should wipe my phone; which I did.
Sadly, I realized that my "wake using volume rocker" option was no longer enabled, and there is no GUI to turn it back on.
I then found a .zip package that was supposed to enable the option but, I guess I went too fast, now my phone is stuck on a bootloop.
THE PROBLEM:
Since my power button is broken, I cannot navigate in the fastboot menu to recovery and fix the ROM.
Worst, since the power button is somehow shorted (i.e.: it powers on automatically when I insert the battery) Fastboot is not working properly and my PC never sees my phone, so you can forget about fastboot boot recovery.img
So: boot loop, power button broke, no recovery, no fastboot. =(
I searched quite a bit and found out you could get the Nexus S in download mode and get it to work with ODIN using a USB JIG.
I made myself such a JIG and successfully put the phone in some kind of download mode where my PC sees it, fastboot devices yields nothing *but* ODIN sees the phone!
So a glimmer of hope except for the fact that finding the .tar files for the Nexus S seems impossible...
Thoughts? Suggestion? TIA!

Oh BTW:
-Yes I saw the other posts, but none of them mention the odin files
-Yes, I know fastboot is better; but it's not working and:
-No, I can't see the device on 3 different PCs using 3 different OSes and 3 Different cables when in fastboot mode
I mean by that last line that *nothing* shows in device manager in Win7 or XP and *nothing* shows in lsusb on ubuntu
So unless someone has an idea it looks like Download mode is the only way my PC sees my phone...

My power button done the same thing, I googled around and found a solution that worked for me.
It's somewhere here on xda but I don't got the link, basically everytime I booted into the bootloader I couldn't move the cursor with the volume button because the phone thought I was holding the power button, so I carefully tapped the casing around the power button and rebooted the bootloader and eventually I had control, it took 5-6 attempts to get it going but it did fix the power button for me.
I think it's something to do with the micro switches giving out after a certain number of uses.
Also it started screwing about recently so I just blew into the casing through the power button and it's behaved ever since.
In short, tap it until it works, once you have control of fastboot plug the usb in and your pc should detect it
Hope this helps, Good Luck

Hey MuckyFox thanks for your reply!
Unfortunately, that would've worked back when the power button was flimsy and still working once in a while... I did try the tapping thing but really nothing works... the button seems entirely dead and shorted. I guess at this point I might've to bring it in for repair... if the power button isn't broken then I'll be able to easily fix everything in recovery or fastboot. Sucks because I feel like I'm so close to getting it to work without spending money XD I just can't find the files for odin even though they really do seem to exist.

Allright so I found some odin files which were said to work with the i9020a
I flashed them... at some point it said "RESET!" and then odin no longer saw the device. The device is now not booting at all. FML

So this thread is going to end up like every other similar thread: I went and bought a Galaxy Nexus ;P
For posterity, these are the files you shouldn't flash on i9020A:
BOOTLOADER : Bootloader_I9020XXJK1.tar
PDA : PDA_SOJU_GRH78_85442_SIGNED.tar
PHONE:
CSC : CSC_I9020_EUR.tar

My power button started failing over the last couple of days. First when I would set the phone to standby it would ask me if I wanted to switch off the device, then later on it wouldnt respond at all.
Really weird solution - boot into recovery, factory restore, clear dalvik cache, voila, works good as new! (aside from losing all my settings)
Note, I barely managed to get into recovery. The power button fully stopped working halfway through and I had to take the battery out and try it a couple of times.
Oddly, even during this uber-broken phase, the power button would always switch on the device when fully switched off (not just standby) indicating to me that it wasnt just a physical broken connection.

I've mentioned this before, but a full casing for the phone with all the buttons is around $10 on eBay

You need stuff for SOJUA, and just the fact CSC has EUR meaning Europe in it would scare the crap out of me. Possible you just flashed stuff meant for i9020T and not i9020A.

In case anybody comes back here, I'm just gonna drop this in.

Request: Surface 2 Recovery USB. Won't boot, flashing 'Surface' every 8 seconds

Hi, so yesterday after powering my Surface 2 down (it was working fine), it no longer boots up. Instead, it will show the 'Surface' on the screen for about a second, and then the screen will go black for 8 seconds, and repeat until I turn it off or the battery dies.
I've been having a hard time finding other people with this problem, but the few I did said that sending it to MS (and getting a new one) is what they had to do. One person did say that they were able to fix the problem with a bootable Surface 2 recovery USB. I have a lot of work on my surface that I don't have copies of, and would really like to be able to save those files.
Things I have tried: Holding the power button with a combination of volume rocker/home key. Holding the power button for 20 seconds followed by 2 seconds off and on. I have fully charged it and know it has enough battery.
Help would be greatly appreciated.

Hi John,
What was the solution to fi this problem?
I encounter the same problem.
Regards,
Hans

You should be saving your stuff to your OneDrive...anywho
If you have a USB recovery drive, you could try booting from it and doing a refresh,(NOT a reset) that would keep your files.
If you don't have a USB recovery drive you could make one using the 8.1 RTM ISO, I wrote a how-to guide here;
http://forums.wpcentral.com/microso...w-install-windows-rt-8-1-rtm-surface-2-a.html
or you could download one here;
https://onedrive.live.com/?cid=203A62CBEDC78BA2&id=203A62CBEDC78BA2!6247&authkey=!AIcBVsLygTfpZxQ
(I think that one is for the UK, but that shouldn't matter, just do a full reset from your recovery once you get your files off)
Hope this helps.

[Q] Recovery mode for Kurio 7S

Hello, I have read a good amount of threads on this site, most have proved helpful in my problems, yet at this time I have not found any thread similar to my needs.
I have a Kurio 7S that needs fixing, it is stuck in a bootloop, I would use the recovery mode to reboot it or reset it if need be, but the power button had stopped working a few days after I had gotten it, we had used the usb port and reset button to turn it on. Now though, none of that is helpful.
I wanted to know if there was a way to use a computer program to open up recovery mode and install a rom, can Android Multi Tool accomplish this?

Not that I've found, but it does seem these cheap tabs have that issue.
The two my nephew's had both had that issue.
I have three press the power button close to the front edge, first plug it in a big of a charge, any different charging cables to rule out bad, and just try listening the plastic to press in you should hear the soft click of the button when it meets up.

Surface RT stuck at surface screen - Normally an android guy

A co worker had her surface rt crash on updating and now its stuck at the booting surface screen.
I tried the steps I could find fiddling with the volume button and power button but it gets no where.
Honestly I have zero experience with these and normally use android.
Is there a way to connect this thing to a PC and push recovery files to it as it doesnt seem to want to see the recovery USB at all. It does know its there cause the power/reading light on the USB drive lights up.
Im trying another attempt at downloading and remaking the recovery USB just to see if I got a bad download but honestly wondering if this thing is toast. Just really trying to help them out cause it just ran out of warranty and MS wants to charge them 200$ to repair it.
Thanks

Hello there,
I would like to propose again this question, I summarize the problem of a Surface,
in my case a Surface 2 with Windows 8.1 RT stuck at the 'Surface Screen' and looping
in reboots alternating with the screen of 'preparing automatic repair', and then stuck.
If I reboot by holding down power button for 10 or 30 seconds, nothing changes and
the loop restarts by telling 'there is a problem screen', automatic reboot, 'Surface screen' and stuck.
I've tryed with 2 versions of the recovery image, an old one and one new, with two different
usb sticks. I've booted with "volume down" etc, the usb light flashes a couple of times but
the loop described above does not change.
Seems that many people out there suffer from the same problem, with almost all versions of the Surface, up to the Pro 4.
Many of them solved it with the usb recovery, but also a lot of them still have the same problem. Maybe we do something wrong
with the recovery files?
Any help is welcome, thanks for reading.

Try to keep the device on charge and leave it running for some hours, does it still stay stuck?

Hello Kephax,
I tried several times many strategies, even the one you suggested, nothing to do, always the same loop.
Hence I contacted Microsoft on 15th december, the support was very polite and efficient, in a week I was able to pack my device and give the pack to UPS. After 3 days, they returned me a new Surface2 for free.
I must say mine was only 6 months old, so warranty was still valid. On 24th december I was playing with the new device, so the whole procedure took 9 days. I am very happy.
However, I cannot say what was the fault of my Surface, a hardware problem or some updated went wrong? that's the question, I'm frightened that it was an update problem and that it can happen again to the new device. I can only guess it was a hardware problem because of the experience with the new device, less laggy, more fluid for graphics animations. Also the battery lasts longer.
I hope that this experience can help other user with same problem.
Best wishes for a happy new year,
dott_mat

Create a surface rt 8.1 bootable usb and boot from usb device.
If USB Device bootable, then first connect usb device, then press and hold vol down button, then press and release power button, when surface logo appears then release vol down button.
If all successful then surface will boot into recovery or directly boot from usb drive.
