3 weeks ago I finally spent the $20.00 and replaced the defected battery in my Sanei N78 tablet. During the week that followed I had no trouble that is till a week later.
After using my Tablet till the battery ran down and shut it self off I plugged it in to recharge. This time however, instead of getting the Android opening screen, I got nothing. So I pressed the power button till the Sanei's logo spinning color wheel page appeared. But, instead of continuing booting on in to the Android opening screen, it just stayed stuck on that spinning color wheel.
Since this has happen to me before I proceeded to use what I call the reset command (pressing the power and up volume buttons simultaneously).
Yet, instead of giving me a choice to reset or not, all I got the Android logo laying on its back with its access panel open and an exclamation point in a red triangle. Which after a few minutes returns to the spinning color wheel page?
I keep trying difference combinations of the power/volume up/volume down buttons; however, all I get is the "dead" Android logo or the spinning color wheel.
I have also tried disconnected the battery and let the Tablet sit unpowered for the next 48 hours - It didn't work:crying:
What has gone wrong?
Has the “drive” containing the Android operation system failed? Has Android itself become corrupted? Is there a fix?
When I asked this question to a site that sell only Sanei tablets I was told to hold the power button for 5 to 10 seconds. Well, I have and nothing changes. I was also informed that another answer is to reinstall the firmware.
As for the latter, I would like to try, but, the only way I could is to download it to a thumb drive from the computer I am using to post this message and either run it off that or use my home Win98 OS computer (BTW: I have connected the tablet to my home computer and while 2 drive icons do appear in My Computer any attemp to open them give me a "drive not ready" message. This because this public computer that I am using will not premit under any cirsumstances a tablet to be connected to it
Is this possible?
If not, then I have another paperweight for my desk

I have a problem with my Galaxy Tab 10.1, yet can't seem to figure out where to start troubleshooting.
Having the Tab since it was released, until now, I had yet to experience any problems whatsoever. But upon turning (or trying) to turn my Tab on, all that welcomed me was a black screen. I know the various button combinations, screen rub trick, and holding the power button long enough to help boot the Tab up but none of this worked. I thought maybe my battery was dead (even though I has seen it at about 60% before the problem) and decided to plug it in.
Once plugged in, the battery charging indicator came on and looked like it was about to show the battery filling up. Instead, the screen turned off immediately one second later and then popped up again with the battery icon. It would then just go on and off. Holding the power button would result in the "Samsung Galaxy Tab 10.1" welcome screen, but this would transition back to the battery icon, and turn off as usual.
I was able to access the two icons (box with an arrow and android; and android with download underneath) by holding power and vol. down. Clicking on the first icon with the box would just turn off the Tab and restart the battery icon. But clicking on the android that has the word download underneath takes me to a screen that I don't know what to do with.
This all happens while plugged in to the charger, and goes away immediately (turns off) if I take out the cord. I have tried to use the NVflash method but am basically stumbling in the dark because my computer doesn't recognize the Tab when I plug it in. It does say installing device when plugged in, but I cannot find it under devices.
Any help would greatly be appreciated!
P.S. My Tab (32 GB) has an unlocked bootloader, but the unlocked sign does not show up when I plug it in and and the Samsung welcome screen breifly pops up.
I am not a developer, so ultimately someone else will help you more than I, however the fact that you can get to ODIN means you will be able to save your tablet. There are some posts in the development section about using ODIN (that’s where you go after selecting the icon on the right), but you will be able to flash everything you need to in order to get back on your feet from within ODIN.
Hey there everyone.
I've been an short term Android user (almost a year now), and I've fell in love with the customization and the flexibility of the platform.I had only recently delved into rooting and ROM-ing on my GS2, which I bought about two months before purchasing the Galaxy Tab 10.1 When the GTab received the OTA, I noticed that ICS with the TouchWiz overlay is either somewhat smooth, or downright laggy. YouTube performance lagged Honeycomb, and that's saying something. Finally, I decided to root my GTab and install CM9/10. I went to the first source I saw (http://forum.xda-developers.com/showthread.php?t=1239185), and to my surprise, I was stuck on step two.
It won't go into download mode. I tried 5 times, each time trying in vain the right volume+power and all three. No luck. (Insert: WTF). Is there something wrong? Everytime I enter the volume down+power, it goes into the Galaxy Tab 10.1 Splash Screen (As it should), and then nothing else. Then it appears again. And then disappears. And Appears. In this infinite loop, with no two icons showing up. If I let go of the buttons, it boots up regularly.
What do you guys think of the problem? Software (Most likely, huh?), or hardware (buttons work flawlessly in use). If not, is there a alternative way to root the device without going into download mode?
Thanks in advance,
Andrew
Power Button and the Volume Down Button pictured here! With Tab completely turned off and the plug not connected hold the power button and the button directly next to it " The left volume button" for up to 10 sec!
Hello,
I think I might be at the end of the road with my tablet. I've never rooted it or tampered with it in an way, however yesterday it locked up so I did the usual soft reset (hold power and vol+ for 10 seconds) I then turned it back on and the sony logo popped up, but there it just hung. If I press and hold the power button it switches off, a brief press on the power button brings it back on in the same state. So I go Googling, including looking at threads on this site, all seemed to advise to try to get the Android recovery menu up. on the Sony this is done by holding the power and vol+ and then releasing the power button (only) when the son logo appears (this process to be started when the tablet is off) so I did this, and no response at all. Worse than that, where it would turn on and instantly hang, it now doesn't turn on at all. Hooking it up to my PC I can see the device in device manager, but it tells me my usb device has malfunctioned.
At the moment, my thoughts are to open it up, to:
1. Check that the power/volume buttons aren't stuck in some way (preventing the boot command being given correctly)
2. Remove and resolder if necessary internal battery to force a power cycle.
3. Bin it and get something new (it is 2.5yrs old so no big loss i suppose)
Any ideas where to look or similar experiences?
Thanks
Hi,
My Zenithink c93 decided not to boot. It gets stuck at the android logo with three horizontal white lines above it going across the screen as soon as I turn it on. I've tried pretty much every button combination (power, back, vol up and vol down), but it didn't work. The only combo that gives a different result is power button + back, which shows the android logo with the words "Upgrading" directly beneath it, then turns off after about 2 seconds. I can't even get into the recovery menu so I'm really stuck. Also, the tablet is not rooted.
Things I've tried:
Wait at the android logo screen for 15 minutes.
Desolder the battery for 10 seconds and solder it back again.
Copy zt-update.zip to the micro-SD card and tried doing the upgrading process.
They all did not solve the problem. How do I fix this?
anyone?!!!
After leaving the tablet to charge overnight, I found that it was stuck on the wave animation. Holding the power button fixed it and gave me the ability to use it again. Unplugged charger and thought tablet was ok. After a while I find that it's stuck in the animation again, so I figure a restart would do it good, after holding the power button for who knows how long I manage to restart it, but it gets stuck at the "restarting" message. After a while it falls asleep and when I wake it up, it is once again stuck in the animation. I hold power button, but this time nothing happens, so I open the micro SD thing next to the charger thing, and press the tiny red thing beside the black thing(sd card?) and it shuts down. Holding the power button to start it takes it first to the Sony text, then some more Sony text, but after that it gets stuck in the wave animation. Another thing to note is that I was using about 90% of it's storage so was thinking this is a reason.
Anyone know of a fix?
I'm open to installing a custom ROM or factory resetting it, don't really have anything important that I want to recover, just want to turn it into something usable again.
A link to one of these guides would be helpful.
When plugging it into PC via USB I cannot get it to show up in xperia Companion. It does show up in Devices I think, but I can't use it for anything.
