My wonderful wife gave me an Acer a500 for Christmas. Awesome gift. I had rooted it immediately with no problems, since all of my phones and families phone are rooted, it just seemed to be the natural thing to do.
As someone that "plays" with their android a lot I did all of the backups. Well, the time came to have my tablet "approved" for use at my company and also have the appropriate "encryption" software and keys added. Just as a precaution I decided to restore the original backup and unroot the tab.
All was going well until I received the update message. I went ahead and downloaded the update and ran it. During the install process it froze. I thought it was just busy so I left it for a good 20 minutes and finally realized it was frozen. I rebooted and it went through a couple of reboots and finally settled on the lock screen. But now I find the touch screen unresponsive.
I plugged in a mouse and keyboard in hopes that I could get back into it and start over, but, although, the mouse shows up, it is jumpy sluggish and will not grab the lock to slide open and eventually freezes.
I have tried all of the "update.zip" files I could find and they all fail at one point or another.
ADB allows me to explore in shell but since I unrooted, I cannot get su privileges.
Acer is of course, useless and the vendor it was purchased from is worthless.
I have been through every thread I could find and tried every trick I could come up with. Now I'm just stuck.
Any help is appreciated
I've had this a couple of times already. Usually just turning the screen off and on a couple of times does the job (the issue seems to be with the driver, also on various custom roms). Just try it after each off-on cycle, most of the time it takes no more than two or three tries, though there are exceptions.
Thanks, but it has been rebooted many many times since it's demise.
Decided to skip sleep tonight and keep plugging away.
I found an update.zip recovery file for an a501. Figured I can't do much worse so I went ahead and ran it.
It froze at about 95% but.........
Good News:
The tablet is responsive and touch panel works again.
Bad News:
It boots straight into system settings and although you can open the settings menu, nothing actually launches.
Decided to try all of the old update.zips and still everything fails.
No more ADB response.
When you originally unrooted your device did you revert back to the stock recovery or did you leave cwm on your device?? If you left cwm on your device that may be the problem with the update.zips and OTAs.
You are sooo right. I've never gone back to a stock rom before and I completely forgot about reverting to the stock recovery.
As a matter of fact, I was on Civato's Flexstriker 3.2.1 rom with the new CWM before I reverted back to the stock rom.
Well, at least we've determined my stupid mistake, but now the question lies: "How do I get back to any working rom?"
Here's an update. I did find an update.zip file that also begins to load but does not finish. It stops at 95% still.
I will attach the photos in case someone notices something otherwise I am at a loss. In addition to all of the above, I tried everything I could to get into APX mode but nothing. I am willing to try almost anything at this point, so all suggestions are appreciated.
Something I noticed was the recovery for the a501 was android with gears spinning in the body. The recovery I have now is a package with an arrow. The recoveries are different. The current update file is Acer_A500_1.145.05_COM_GEN1
So this brings me to a question: Can I put Thor's 1.6 CWM back on the a500 and at least work from there? I do have my original backups and thought I might be able to get somewhere that way.
FIX AVAILABLE!!
I bought my TF about 15 days ago, rooted it and installed CWM recovery, and it was running just great. Then, the ICS update came along and i just waited for the CWM package to update mine. No problems in the update process, but the random reboots started happening, so i thought the problem was that i updated without wiping, so i did this. No dice, still getting (not so) random reboots. So, i thought maybe it was the CWM package. I downgraded to HC via NVFlash, then let it update via FOTA. Even then, the random reboots persisted. Then, i noticed the tablet never rebooted while in use, but only while in deep sleep state. The "No Sleep" widget is the current workaround, but then, you risk getting a SOD.
So, from what i could gather until now, the following things are NOT the cause for the RRs:
1. Updating without wiping.
2. Updating via CWM.
3. Rooting.
Well, i got really sick of this problem, so it's time to do something about it. I am trying to gather as much info as possible to try and narrow down the possible cause for the random reboots, so i need everyone that is facing the same issue to give me the following info:
1. Serial number of your Transformer
2. Firmware region (TW, US or WW)
3. Logcat before the reboot
For number 3, you need to open Terminal Emulator, and do this:
# su -
# logcat > /sdcard/logcat.txt
Then you just turn off the screen and let your tablet go to deep sleep. After it reboots, post here the info above and attach logcat.txt.
Please, only use this thread to post the info i asked. Thanks!
Update: Some users contacted ASUS and it seems they are aware of the problem. A fix is supposed to released soon, in the form of another OTA update.
Update2: Very good knews for rooted users. The test13 version of guevor's kernel is able to let the TF deep sleep and not reboot. Link to his thread:

THANK YOU, GUEVOR!
Good idea. Mine just randomly shuts down during sleep, as opposed to rebooting. Shall I contribute too?
Have you tried a factory reset?

I was able to caught one of the reboots (it's freeze on the ASUS logo) and when i hard reboot it, during boot sequence appear some message saying that was finalizing update (this was after the FOTA and after other 2 random reboots. I did reboot the device after the update at least twice before experiencing the 1st Random Reboot).

Every kind of update method that you can think of was tried. In that case, yes, it was wiped. Several times, in fact.
Please, post just what i asked. I want this info to investigate the issue. Post on another thread if you want to share theories or something else.

Mine was never rooted, 100% stock, took the ICS OTA on Friday moring, ran great all day, I woke up Saturday morning (I had docked it and put the doc on the charger friday night when I went to bed) and it was stuck in a boot loop. Now I'm looking at how to NVFLASH it back to honey comb to recover it, might as well root it now.

still waiting to freeze or reboot ... for now 493K of logcat

This is going to be a problem in the kernel like it has been on previous releases. When kernel source is released then the kernel devs will fix it and then asus will fix it. My SODs are caused by a kernel panic so until we get an updated kernel we need to get asus to release source.
I am mostly a longtime lurker/user of XDA but I thought I should contribute to this thread.
Bone Stock 16g TF101-A1, Refurb purchased last week from online vendor. Still getting used to the tablet format but I also purchased a TF101 Dock.
I noticed yesterday that I had a couple of random re-boots. Didn't know if it was related to an update or why this particular tablet was "refurbished." About 7 hours ago, this morning, I got multiple re-boots. Splash screen then power off and on again. I saw at least 15 re-boots before I started looking around for solutions. I tried the stock rom (downloaded from Asus) and re-boot to recovery w/o any success. Re-booted and wiped (hard reset) multiple times as well.
Still no complete boot but I had two separate and distinct paths that displayed:
1. it would boot with an android bot asking for a password and the keyboard displayed
2. It would cold boot into the "Start" screen like a normal set up.
I did manage to get the recovery started only to reach the bot with the exclamation point and no further progress at recovery.
In either case, typing a password of any kind did nothing, and hitting start and beginning the set up process did nothing but continue the re-boots/splash screen/power up/power down.
Finally connected to my laptop and it succeed in a complete boot and I was able to set up and connect to my wireless. It did not re-boot for several moments and I was able to observe the "About" page from the settings. I was still running
HTK75.US_epad-8.6.5.21-20111216
I also noticed that it was actively downloading a "firmware update" I went through several more re-boots until it finished the download and then I installed the firmware w/o any further trouble. In watching the download, I noticed re-boots at 31%, 32%, 41% "download completion", and one or two more before it fully downloaded. Of course, it did re-boot upon completion of the upgrade.
I am now running Android version: 4.0.3 Build number: IML74K.US_epad-9.2.1.11-20110221
Everything has been stable for an hour or so of moderate use including installation of multiple apps.
FWIW, I think that the reason my problem started is that I had my WiFi set to turn off when screen is off. I believe my incomplete download started the re-boots and my settings "may" have contributed to the incomplete downloads that started the rest of my issues.
Thanks to all of the "regulars" around here that are busy helping us customize our devices. This may not be my first post, but I think I have less than 5 posts right now. Hope this helps in discovering the causes of the re-boots.
ICS OTA on Saturday, 2 reboots already, stock rom, 100% original, Italy. Should i contact Asus?

I have experienced a single random reboot since applying the OTA ICS upgrade to my US B70 TF101.
That was then...
Now the tablet is virtually unuseable. Not only are there random reboots, but lags and freezes ad nauseum. I am NOT a happy camper
I don't believe this has been mentioned before.
I just saw my device go into random reboot in sleep. However, this time the device completed the boot up sequence instead of getting stuck on the Asus loading screen...
All I did different was changing WIFI sleep policy from "never" to "on during sleep", which I don't think is the cause of the change.. I guess it all depends on luck weather the device gets stuck or complete the boot up sequence.
So perhaps the problem is caused by a combination of a bug in the deep sleep state and the CPU governor?... This is purely my speculation.

My device never gets stuck in the ASUS logo, it always completes the boot process, and the wifi policy is the default one, so i don't think it's related to it. But it's probably something to do with the kernel and deep sleep state. Even with the wifi policy set to never turn off, the device enters DS.

reboot cant have anything to do with the apps (like google earth) as those will simply FC on fault and are not capable of taking system down. this must be a kernel or driver issue.
transformer prime got ota update recently that was supposed to fix reboots and it contained new wifi driver. so possibly this is something to do with wifi.
my wifi sleep policy setting is to be always on when on power and sleep when screen is off on battery.
never had a reboot when plugged in, had a few always on battery power - so it might be related to wifi beign powered on in sleep to do periodical email check. just a guess.
I am running stock unrooted atm. I reverted back from rooted to stock before the ota update.
I generally get one random reboot each day. They happen when my transformer is in sleep mode always. It'll be st next to me asleep and then I notice the screen turn on and it is rebooting. My "Keep Wi-Fi on during sleep" is set to "Always".
I removed root as I wanted to see what stock performance was like. Apart from these reboots I'm totally happy.
2.6.39.4 and WW_9.2.1.11
Not sure how much help that'll be to others, but there you go.
I had these random reboots aswell on my device but since yesterday morning it stopped.
- Removed SetCPU
- Forced 2D rendering to the GPU.
Still testing it but so far no reboots
Stock ICS + Root
Getting the same exact thing, froze during boot up one time.
Running S/N BBO
Tossed a ticket into Asus letting them know, hopefully I get a response back soon.
I had random reboots the first day after updating,
but have set
1. the wifi to be off when the screen is turned off (in wifi settings), and
2. have turned off the location service that uses your wifi to aid positioning (in location settings).
and this seems to have stopped the reboots.
Hope this helps someone.
I successfully rooted my Tab from ICS to JB 4.1.2 a few days ago and it has been working fine. It suddenly froze in GMail app this evening. Held down power and attempted reboot. All fine until several revs of the CyanogenMod circle then it froze for a few seconds and then blank screened and rebooted with the Samsung Galaxy Tab 10.1 logo before going back to the CyanogenMod circle. Only stops the looping if I power from the mains. Battery is at about 55% and charging.
I have CWM-based Recovery v6.0.1.5 and I installed JB from cm-10-20121112-EXPERIMENTAL-p4wifi.zip
Can anyone help? I'm new to rooting etc..
Many thanks,
Stuart
Try booting into recovery and doing a full wipe of everything.

Many thanks for the reply SouthPhilly. It didn't work
There seemed to be a problem with formating /data. It just stopped when I tried it. Also stopped if I tried restore. The good news is that I did eventually overcome the problem by following qbking77's excellent info on
How to Unroot / Unbrick the Samsung Galaxy Tab 10.1 - Latest at www dot youtube dot com/watch?v=KYBs98R9rTs with file info at
www dot qbking77 dot com/samsung-galaxy-tab-1012.html
which results in a stock original unrooted GT-7510. From there I rooted back into CWM recovery and reflashed CM10 so I'm back with a working version of 4.1.2
I hope this info may help others unfortunate enough to get stuck like me.
I'm now happy again.
Best wishes to all.
Stuart G3SNA (QTHR)
Well perhaps not quite so happy!
For some strange reason I could not get the USB port to work. It did with my first attempt at flashing to CM 10 - JB 4.1.2 days ago but not now. I have tried all ways several times so eventually I returned to the qbking77 version of the stock 3.2, copied my CWM backups back to the sdcard, then reinstalled CWM recovery and restored from the backup. I now have what appears to be a fully working tab with USB connectivity running 4.0.4 ICS again. I'll stay with this untill JB gets a bit more stable. You never know, pink pigs may fly and Samsung may issue an OTA update :laugh:
Why didn't you flash a nightly instead of a ROM thats dated last month? The latest one runs fine on my p7510
http://get.cm/?device=p4wifi
Sent from my GT-I9100
I didn't know where to find the nightly files when I first did the root and rom flash. I just followed the links I could find using google. The whole thing looked good to start with and I ran it for the best part of a week before it froze up on me. I learned a lot in the last few days and now feel confident in what I'm doing. I did download last night's nightly this morning and flashed the rom. When I connected the usb cable to my pc failed to connect so I reverted to my original zip file thinking the nightly had an issue. Low and behold the usb cable connection failed with this as well. In both cases I did all the wipes and formats just like the first time. After that I gave up and decided to try to put my Tab back to ICS using the CWM backup I made as recommended before I started the first time. I'm no novice as far as computing is concerned but I haven't rooted an android device before.
If you take a look around the forums here you will find I am not the first to fail to find the nightly files. Perhaps a sticky with the link would be useful?
well here we go again. i push installed "gl tron" from the play store on my pc to my tablet. it showed it installed successfully. i then went to play "samurais vs zombies" and it crashed as it sometimes does for me. so i went to restart my tablet and now its stuck on the android logo with gears moving. last time it did this i tried random fixes and just made it worse and practically bricked it and some good guys here helped me get it up and running again. is there any easy fix for this not to lose all my data or make the issue worse? if not, what should i do to get it to work even if i lose my data? from what i understood last time was i had an issue in the data/media directory causing the issue. is that the case most likely this time? was it from the push install as i suspect, because it is very similar to what happened last time? i never got to do a proper cwm backup of my rom and data as i got an error and never fiddled with it again. some ideas or pointing in the right direction would be very helpful. i also would like info on how this could happen and how android works in order to avoid this in the future. thanks so much.

Can you go to recovery. "clean up tab" then reinstall your ROM?
This won't touch your data and - may - get you running again.

i went to recovery but could not find a "clean up" selection. am i missing something? last time this happened, i tried to do a factory reset and all i got afterward was a droid with exclamation mark on his chest. from what i understood is that my a500 did not have a proper recovery partition which left my tablet nearly bricked. that's what i surmised from the info i read. thanks ta-wan.
wiped data/media and it set me back to honeycomb. i rebooted into recovery and installed lightspeed 4.8. lost all data but whatevs, my fault for not backing up. wont happen to me again...
OK first, I will say that I have been reading for days and days and am getting nowhere at all. I am running out of time as I am leaving Monday backpacking from OKC to Portland to meet a friend, then proceeding immediately to about 35 national parks. I HAVE to get this thing functional so that I can depend on it on the road for communication. Its current state makes me nervous. I got this tablet already rooted, custom stock rom, and with an unlocked ICS boot loader version 0.3.11. The only problems with it were the common charger/screen response issue. For $100, I can deal with that.
I flashed the Lightspeed from from the main list, everything went well... Until it rebooted the first time. Since then, directly after the bootloader screen, it briefly shows what looks like semi-colorful TV static, then shows boot animation and boots into the OS. It has never frozen on either screen.
I decided Lightspeed was not at all what I wanted, so I flashed CM10. I have yet to find anywhere in the Aroma installer where I can choose the apps installed, ONLY THEME CUSTOMIZATION. After the flash, it kept the boot animation from CM, and loaded right back into what looked like Lightspeed, and shows Lightspeed in the about menu also. I reflashed it, choosing a different boot animation to test, and did the same thing again, except it loaded ZERO extra apps at all, not even the stock bloatware. Nothing from any of the 3 roms. I reflashed Lightspeed, same thing again. No extra apps and just bare basic stuff. EXCEPT SUPERUSER. THAT DID LOAD ONTO IT EACH TIME. I haven't lost root access, the recovery works fine.
I flashed the V8 bootloader, and tried the above again. Same issues still. All of them. I have read until I'm blue in the face. If there is a way to fix this without using a PC, that would be grand. I have very limited PC access.
Anyone have any ideas? I have followed every single step 100%, I'm positive. I'm not new to rooting, flashing, and jailbreaking (doesn't apply here I know),"so lay it on me.
EDIT- I downloaded the 4.0.4 FLEX-Reaper rom and going to try that now and then I give up for the night. Tomorrow is the last day I have to mess with this before I leave. I tried to upload screenshots of the problems, but it won't let me attach them. Maybe that is another problem. Ugh who knows. Help
EDIT- That rom bricked my tablet. Through that brick, I found a working solution for the SoD, found a way to recover without files on external SD, *THIS FIXES THE BRICKS CAUSED BY CM10 AND REFLEX!!!* and I didn't lose anything. This thing is back in pristine order. I can finally sleep! Will post later on how I did it. I need sleep now.
