[Q] Bootloop on stock 3.2 - Eee Pad Transformer Q&A, Help & Troubleshooting

Is there any way out? TF boots, flashes locked screen for a second and reboots.
I can shut it down with holding Power+Volume Up for 10 sec, I tried to "cold boot" it with Power+Volume Down but no luck, it just goes into the loop again. Maybe I've done it wrong when there were two shapes on the screen - "Wipe data" and "Anrdoid", volume down seem to toggle them. I think I tried both.
Will this "Wipe data" lose ALL my downloaded apps etc? Will I have to reenter a million of passwords again?
Wifi sometimes shows "No internet connection", sometimes "SMC" - my home network, the icon is gray with occasional little symbols on it, too.
I tried turning the router off and starting TF with wifi tether on my phone and it should remember the settings but it just shows "No internet connection" and reboots.
I took the microSD out, too.
I once saw an Anrdoid Robot with a big orange exclamation mark but it didn't do anything for a while so I just shut it down again. Should I wait a bit longer? I can't find the combination that got me into that screen again, too.
It doesn't actually reboot per se, it shows the "Asus, perpetual perfection" with a running gear screen.
All other threads about boot loop here are about rooted Transformers, not surprisingly, and the solution is to flash a better Rom or to do it properly.
What about unrooted device? What is the proper way to recover the tablet?

Had to wipe in the end.
Yesterday it happened again, so I wiped it again.
This time I rooted and installed Titanium Backup, at least recovering will be easier.
So I guess that is the answer.
Pure, "one-click" root, as per
http://forum.xda-developers.com/showthread.php?t=1198303
still keeps OTAs coming in case Asus figures the solution

[Q] My TF101 stuck at EEE Pad Blue Bar screen!!!

Hi All,
I had ICS installed on my TF101. However yesterday it totally discharged when it was asleep and I had trouble turning it on. I never had this happen with HC. So I decided to go back to HC. I had my tablet rooted and su backed up. Had recovery installed.
I flashed official US HC fw and everything went fine until I tried to reboot the tablet. It's now stuck at the EEE Pad loading logo with the blue bar approximately half filled in. No amount of button combinations does anything. I can't enter Vol + & Pow button to enter ADB, and when I try to enter recovery mode, the white text shows up saying searching for OTA recovery and that's it, still gets stuck at the blue bar.
Any ideas or ways to get to my recovery before I return my 2nd tf101? Thanks!!
(Btw, I'm not a newbie, I would NEVER do this whole thing if ICS was stable and worked like it's supposed to, but I refuse to own a 390$ half working tablet that crashes, has battery drain issue and gfx glitches after the FORCED ICS update!)
Have you tried cold-booting it? (power + vol-, wait untill you get the option to cold boot or wipe)
Also, I dont understand what you mean by "forced ics update". I ran my TF for several days without updating (albeit, with the annoying icon in the notification area).
Although I guess you bought the tablet new and recently Im still going to ask. Whats your serial number (3 first)?

Hi Goatshocker!
I have tried to cold boot it, but it does not allow me to get to the 2 icons you're talking about. When I hold down Vol - & Pow, it shows the regular white letters from bootloader, and gets stuck at the blue loading bar EEE Pad screen.
What I meant by force, is that after 4 delays of the update, ICS will install itself automatically! Even when the tablet is in sleep mode. That's what mine did.
In order to avoid this, the user would have to root his tablet and use Titanium Backup Pro, and disable certain system update processes. Which is NOT for the casual user or for anyone who wants to keep warranty intact.
The s/n I have starts with C2O.

Fighting a lost cause?

I've got a rooted (Super SU, but the original root manager was Superuser) LG C800 that I was having problems with. To be specific, I installed some apps on to the system. Some of these apps would be Titanium Backup for root, Avast Mobile Security, ROM Tool Box Lite, Super SU, and a quite a few others. From day one they seem to be kicked right back to my S.D. card, but not all at the same time, and some would stay on the system. I read where I should move the apps back to my S.D. card and try to re-install them on the system minus the data. When I did, the phone went nuts. Now it stays in a restart mode but never fully boots up. Can I salvage it, and if so, please tell me how?! I have tried the hard reset/recovery boot where you hold down the power button, volume, and a few other keys, but it did not work. I'm a broke college student and can't really afford to buy a new phone. I used this one for everything including tethering it to get my assignments done at home and turned in on time. Please help! I'm open to suggestions....... My phone will be completely off. When I plug it into my computer, via U.S.B., it automatically turns it on whether I want it to be on or not. Then it starts off in "reboot recovery" mode, will boot all the way to the point to where the home screen would normally turn on, but then it starts in that "boot loop" all over again but never fully boots up before going back to the beginning of that "boot loop" yet again. I can't even get it to register on my laptop as being plugged in. The reason I took the apps I placed on the system off was because sometimes when I'd re-boot the system the apps would be on the system and sometimes back on my S.D. card without my involvement of any kind other than rebooting my phone. Is completing a Nandroid recovery or re-installation of my ROM even possible with my computer no longer recognizing it as even being plugged in? From what I can tell it won't be. Am I fighting a lost cause or is it salvageable?
Rooted myTouch Q 4G, a.k.a. LG C800
I believe it has a 2.3.4 GRJ22-perf, and then something like 2.6.35.7? I can't remember off the top of my head, and I can't pull it up on my phone anymore or else I'd double check.
Have you tried booting into recovery?
(More about my phone from the original post) Honestly.........I'm not what you may consider technologically inclined. I have however done about as much research online concerning this matter as any one person can do. I've looked it up on all major sites, and many smaller ones too, that post remedies for phone, or "human" if you'd rather, malfunctions. They all talk about still being able to reach a home screen or doing the whole holding the power and volume decrease buttons until I "reboot recovery" screen appears (if that's what you're referring to as doing a recovery reboot as). Don't forget the one where you hold hold the power and volume decrease buttons along with the "A" and "F" keys as well. I even tried one from here where you're supposed to push the genius button after the Android figure leaves the screen. My phone won't allow me to do either. Basically if it's online, I myself, or this girl that's been staying with me, have tried it without any results. On the initial boot the Android figure and the box with the arrow coming out of it show up and it boots until just about the point that it use to switch over to the home screen and it will start the whole "boot loop" over again. The thing is though that the Android figure and box aren't there any other time after the first boot, and with every boot loop it makes after that, the time is reduced from the beginning of the loop to the end when it starts all over again. The phone won't shut off unless I remove the battery and even though my laptop no longer recognizes the device, when I plug my phone into it or another power source and it's off, it automatically turns itself on and begins that boot loop all over again. there is one thing I have yet to try. I read on one site where I could download a custom ROM on my S.D. and then try reboot it, but it never makes it to the point in which the files on my S.D. card are ran, much less scanned. I am still 100% open to any and all suggestions in the diagnosis of this issue. I may record and place a video on one of the more popular "tube" sites to better show or further explain what's happening and then come back on here to post the link?! Feel free to reply back if it's possible you can help before I'm able to complete that later this evening. And thanks for any and all help in advance to everyone.

So my Nexus 5 died after hard-reseting after OTA update to 5.0

Hey there.
So today, after waiting what seemed like forever for the OTA update to reach my phone, it finally did!
I got some lollipop on my Nexus phone finally.
It installed no sweat, although it took a while since I have so many apps installed.
So, I had planned to reset the phone after I updated it. I made backups of all relevant data and proceeded to hard-reset it through settings menu.
It started the process, took a while longer than I expected, and then out of nowhere... it crashes, or at least I think it did. The "working" android animation with the "Erasing..." message changed into one with a Red exclamation mark on top of it.
I waited for a while... nothing.
So I powered it down.
Power back on and it goes into the Erasing operation again... except now I don't think it's actually doing anything since it's taking forever.
I've went into the "hard reset" menu that you get into by pressing volume + & - and the power button while turning it on, tried the recovery... nothing. It restarts the phone and shows the "erasing" animation again.
Did I manage to brick my phone while using just stock "tools" ?!
Any advice?
Phone was all stock, no root, no unlocked bootloader, nothing.
Why did you reset it during
Because it apparently crashed mid-way.
The "working" animation changed into one where's a droid with a open stomach with a red exclamation mark over it.
I waited for a long time and it didn't move along so I restarted it.
Anyway, it took forever but it completed it now.
Guess I "just" had to be patient. Didn't expect this to take 40minutes or so with a simple reset =|

[Q] DESPERATE HERE: Phone won't boot after soft reset?

A couple of months back I decided to root my device. I did this using the unlocking the bootloader method. As a result, I lost my DRM keys, and I managed to restore DRM function by following the methods detailed here: http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
I had to download the stock Android 4.4.4 from online, which I flashed my phone with - no problems. Things ran smoothly from then for about a month, and then I realised that my cellular network started to malfunction, and I couldn't access apps like YouTube and Snapchat on the cellular network. This prompted me today to do a "soft reset" of my phone, by holding the power button and volume up button simultaneously for about 3 seconds - under the impression that it would restore my phone settings back to the factory default.
Much to my horror, the worst case scenario happened. When I performed the soft reset, my phone vibrated 3 times and switched off. When I tried to turn it back on, it would show the boot-up screen indicating "SONY", followed by the next screen indicating "powered by android", and then it would show the blue screen with the wavy lines. It stayed on this screen for about 20 minutes. I figured something was wrong, and I tried to soft reset it again, only to be stuck at the blue screen once again. I decided to let it stay that way for 2 more hours, in order to drain the battery. When the battery drained, I turned it back on, and it was still stuck at the blue wavy screen.
I don't know a whole lot about Android phones, and I have no idea why this is happening, but it is causing me an immense amount of frustration - I have invaluable data on that phone, and to lose it would just be devastating. I can't even begin to describe it. I'm using TWRP recovery, and I'm also using TitaniumBackup which is backed up onto my phone's internal storage, and I can't access any of the files on my phone from my computer, because it doesn't recognise my phone.
This has been a long one, thanks for bearing with me. I've got a few questions:
1. What's the problem that's preventing my phone from booting?
2. How do I fix it?
3. If it's unfixable, how can I retrieve my data from my phone?
Really, really hoping someone can help me out on this - I'm completely lost and am desperate here. Thank you in advance!
Can you boot into TWRP's recovery mode using the volume down key?
Just press volume down when you see the green light on your notification led upon powering on your phone
Well something keeps the phone to boot, try to clean cache in recovery, it might help.
But to restore data on internal storage, count it as unpossible.

Please Help! Stuck at boot screen...

Hello. Sorry in advance if this is the wrong thread. I own a pretty old 1 year old tablet that currently has a problem.
Important info: Android 5, No access to a computer for 2 weeks (vacation), slightly cracked screen (still works), I had to install a Play Store apk as the one I had previously was corrupt. Tablet was functioning fine until the moment of the incident (except for the play store apk, which I later fixed).
Minor detail: Once the screen turns on after a restart the pixels near the top of the screen seem to turn purple for a second when I tilt the tablet.
Here is the story:
I was watching a YouTube video and suddenly my tablet froze. I thought: "Uhh, another freeze how annoying," and waited for it to load. I did not unfreeze. I thought: "Well, I guess I'll be fine if I turn my tablet off and on. This is where I got worried. My Power key was not responding. I tried the volume keys. Nothing. I tried connecting a mouse and moving it around. Still nothing. I thought "Ok, lets try restarting it" I did that by holding the Power key down for 10 seconds. To my relief, it turned off. But when it was turning back on again, it was at the loading screen for a little to long. It usually takes 5 seconds to get past the loading screen and enter the boot screen. I decided to wait. 1 minute: nothing. 5 minutes: nothing. I got worried. I tried restarting the tablet again. I restarted successfully but was stuck at the loading screen again. The was no movement on the screen. Only the loading screen. I decided to try the restart backup button which I could activate by putting a pin in a small hole at the back. It had the same effect holding down the power key had. I decided to ue my backup plan: recovery mode. I successfully entered recovery mode. I chose the option "clear cache" and tried to boot again. No changes. I did a scan for any root errors. it said that there were 5 errors, but there was nothing I could do about that. I tried doing a factory reset, then booting up. The reset was successful, but I got the same effect as always. No changes. I gave up and tried to google a solution on my phone. Most of them told me to install a PC program, but one told me to do the same thing I already did: reset, restart. So I decided to let the tablet sit with the boot screen for 2 hours. When I came back, there was no change at all. I tried searching again for a solution. A YouTube video said that the boot time after factory resets may be long, so I decided to reset and let it sit for a bit. 20 mins later, no changes at all. Finally, I gave up and now try to ask for help here.

Was your device rooted? Did you have TWRP custom recovery installed? If you don't have either of these two things then your only option is to flash the stock firmware via PC.
Do a google for:
"Return to stock (your model number)"
If what you need is out there somewhere, that woll find the instructions, the tools and the file(s) you need.
