Up for any suggestions/ help??

Uhm, long story short My Evo crapped out on me with the endless booting. Now before I get trolled. Yes, I have research this issue for several days now yielding little to no results. I went from only seeing a black screen to the constant reboot after the "drag to unlock screen". The phone has a mind of its own only working when ever it wants to. But after a reboot or a battery pull the cycle begins again until it decides that it wants to run again. So the cards are on the table, I'm up for any suggestions, tips and so what you want to throw at me.
What I've done:
flashing the RUU as a .exe as well as .zip file
OTA Update (gave me the black screen)
Thanks, Don

boot into recovery and wipe all the data then install the rom again?

Sorry, I forgot to mention that I was NOT rooted. But, I tried that through the stock recovery (holding volume down+ power through the recovery screen) ANd nothing. Same results.This phone will not defeat me!!

I don't know if this would help. I found this thread:
http://forum.xda-developers.com/showthread.php?t=1302172
You could download the PC36IMG zip and use the bootloader to restore the phone.
If you are not on Sprint, you could do a search for a stock unrooted ROM for your carrier.

Ok if your not a rooted user, which as you say your not, hold your volume button down and power button (after you remove your battery and put it back in), then let go when your screen turns on. You should be at a recovery, find factory reset. All this will do is put your phone back to factory defaults. All your contacts are automatically on your gmail, and will sync to your phone as soon as you sign in with it after your factory reset

Tried this too. I ended up rooting it yesterday using the revolutionary method, hoping that flashing a custom rom could possibly fix the corrupted file or w.e could be causing this, but nothing. This is ridiculous, is it possible that it could be a hardware defect?? If I ever get it booted again, ill post the hardware specs.
Thanks once again,Don.
Update:
currently I managed to get Myn's twopointtwo ROM functioning properly for the time being at least.

[Q] hc 3.2 rom?

I'm currently trying to downgrade my Acer a100 to hc 3.2 from the glitched up version of ics 4.0. I found several threads with a link to the download but the link appears to be dead. When I try to download it appears to try to fetch it but ends as download unsuccessfully. Does anyone have an answer for this? Thanks.

Have you tried just doing a factory reset on the ICS your on to see if it clears anything up?
If you need it, Here<< is the post I used to downgrade to 3.2.1, keep in mind that you will most likely need to factory reset after the tablet reboots. It might hang on the android logo. Just power down then follow the hard reset from the recovery to get it to go.

Yes. I tried the factory reset but it still hangs up when using apps, browser, email, etc. Constant hang ups. Btw, I got the from downloaded but now it will not extract. Any ideas? I've tried win zip, unrar, and archidroid to no avail.

You don't extract it. You need to rename it "update.zip" (make sure not to rename it "update.zip.zip"). Place it on the root of a freshly formatted microSD card. Then put it in the powered down tablet. Press and hold simultaneously the power button, and the volume down rocker (the one closest to the corner), until the tab vibrates. Then release, and you will see the it finding and installing the update file. After it restarts, if it hangs on the android logo (give it 5-10 minutes), perform the factory reset.

Gotcha, so there is noway to load it using the native memory or internal memory on the device? Or would that be a no-no anyways in the case it crashes during loading lol?
Thanks in advance!

You never want to flash from internal memory, if something goes wrong you'll lose the file in the middle flashing right after your stuff is formatted. It may or may not format /data but if it does all of it, there goes internal SD.
Update.zip method is run from external SD I don't think it even checks internal SD when looking.

Ok. I see. But I'm still a little confused. I've finally got the file downloaded and placed on the sd card. Which I might add was ridiculous as apparently it can't be placed on there manually without placing the file on a pc and loading it that way. Nonetheless, how exactly do I flash it now. I have it named update.zip.
Sorry for the confused remarks and questions. I'm use to Windows and have little experience with Linux based platforms. It seems as if Acer intentionally locked a lot of features on the a100 such as host usb ports, movable file systems, etc. Unless I'm dreaming here lol. Either way I like the tablet for the price.
Thanks.

Move the lock switch to lock and back a few times until it says resetting or whatever it says I forgot lol sorry

Omg, thank you so much for posting the links to get the HC 3.2 stock ROM! You are a lifesaver. I had issues after an update where the wifi on this tablet wouldn't connect to any router. I had almost given up until I found your post. Now I have ICS 4.0.3 on this thing!!!

I also have the same problem no one can answer.

OK. Finally got it... I think. Here's what I had to do. Because the rom download kept faulting out randomly on download, I ended up using my laptop to download a program called download accelerator plus (dap) from old version.com. I then used its download manager to complete the download. I know... crazy, but it did the trick. The rest was per the directions given by other users on xda.

Hey, really sorry to post in a dead thread, but I can't find a working download link for 3.2 anywhere; it appears that the site is down. You guys seem to have downloaded it successfully though, so I was wondering if maybe one of you could put it on rapidshare or something? I very much need it, and I would appreciate a working download link. Thanks.

This one is 3.2.1. Remember if you are gong from 4.0 to 3.2, after the update goes through and it reboots, it might hang on the android logo. You need to factory reset to get it back.
1. Place the rotation lock switch in the up position
2. Press and hold the Volume down button, which is located farthest from the rotation lock
3. With the Volume down button held, press and hold the Power button for 3 seconds then release it. Continue holding the Volume down button.
4. Once the tablet vibrates, switch the rotation lock on and off repeatedly while still holding the Volume down button.
5. Release the Volume down button and stop switching the rotation lock once the "Erasing Userdata..." message appears in the upper left corner of the screen
6. Once the factory reset has been completed your tablet will load to the Welcome screen.
7. Your Factory Data Reset has completed now follow the onscreen steps to setup your tablet.

It will work on any ROM, its built into the boot process, so yeah, use it on anything installed it'll reset.
Edit: I was assuming you meant the reset thing, not the process of downgrading.

[q] need help

I bought the kids A100's last year for Christmas. I ended up un locking the bootloader because the ICS update was WAY too slow for my liking. Two weeks ago my sons decides that the unlock pattern is not going to work. You can get the screen to respond in a couple of spots and then go from there but the lines are jittery. I figure that it might need to have a hardware reset. Do that and get a screen with the bootloader info instead of erasing cache..
Find the sd card I had all the info on and tried to do a master rest. NO go. Brings me back to ICS and his lock pattern. I cannot remember how I unlocked the bootloader, did not add it to my favorites or anything else. Now I am stuck. If I am looking at this right the bootloader is unlocked and needs to be locked before I can do a recovery? Is that correct and how do I get that done and do a factory hardware reset?
Worried that if I call ACER with this I will void his warranty.

Power off, then hold power + furthest from the lock switch, press and hold power then toggle the lock switch a few times when the screen turns on to reset. It didn't reset if there is still a lock screen there.
Edit: forgot to mention, holding volume - while powering on will boot into recovery which if its twrp or cwm you can factory reset there, install a new ROM etc.

You definetly need to find out what you have done. As in if the bootloader is definetly unlocked and if you have a custom recovery. Just because it is not neccesary to do anything (ie: root, unlock or recovery) if you just wanted to flash a leaked ICS or the official.
Like Pio said, if you have a custom recovery, boot to it and factory reset/wipe data from there, or flash another rom/reflash. I'm not sure how the tab will react if you do a stock factory reset with the button sequence when you are rooted, unlocked bootloader, and custom recovery.
If the screen only responds in a few places, and is gittery in others, it could be a problem with the digitizer. Digitzer problems are reletively common on the A100. It would covered under warranty if you still have one. If it turns out nothing fixes it, I would restock it though with this concern. They may ***** if they can see it was flashed, if it was bricked it would be a different story.

I used a post on here to go from HC to ICS. Basically It was rolling the HC back first to get the update to push from Acer. I tried to find the post but am having a hard time finding it, and my dumb ass didn't subscribe to it.
This was about in April of this year.
Now when I try to do a hard reset (power + vol down + switch lock) it goes to a black screen with USB bootloader info in the top right corner (near the vol switch). I don't have it with me so I cant tell you right now exactly what it says.
I would have posted sooner, but didn't get emails that there were responses.
Thanks for everyone trying to help. I will try to get back on this this afternoon.

I take it you did the process of going back to HC already and now you can't boot? If its saying its boot loader info in the right corner then its certainly not an ICS boot loader, thats in the upper left corner. It also says ICS in it. Let us know what its actually saying when you boot and we can go from there.

I will. I also turned on the email instant notification that I know that there are responses. Can't believe that I didn't do that before.

OK top left of the screen where the volume button reads:
Bootloader v0.03.13-ics: Starting Fastboot USB download protocol
This time I was able to do the erase user data. Got to the Welcome screen with the language and Country. Cant get the screen to respond.I am guessing at this point that the screen is shot and needs to be replaced (under warranty) however I need to make sure that this is set to Factory specs so that I don't have to worry about voiding the warranty.

It sounds stock to me. From what you have said, I think all you did was revert back to a HC version to get the ICS update ( which some did bck when ics came out if their version wasnt getting the update). If you did this a few months ago, you are just running a stock ICS version.

If that is the case is something missing from the ROM that I cannot get it to reconfigure everything automatically? I thought that it should go directly to the recovery information and reflash the entire tablet (may have the terminology screwed up).

If your talking about Google's sync. If you have it turned on and sync'ed prior to a factory reset, and turned on after. It will sync some stuff, it may restore your desktop wallpaper, contacts, WiFi info and some apps. But it will not restore it perfectly. Either way if your screen is still messed up, I think your OK to warranty it. IMO. Verified if your bootloader is locked, and under settings > about tablet, you are running ICS version 4.0.3 with a stock Acer build number.

I cant get there though. The screen will not respobd to input. I was going to try a bt mouse and keyboard but not having screen inputs puts a damper on that.
And about reconfiguring I was refering to the os and stock software not yhe stuff from play.

Ah I think you mean a factory reset. It doesn't flash anything, it erases /cache and /data (not /data/media but that's another story) and let's the system purge any settings apps or data causing issues.
The system itself is left untouched, if its rooted it stays rooted, if something is corrupted or damaged or missing, it stays that way through a reset.
To replace the system itself you'll need to attempt to flash a stock ROM zip named update.zip on the root of your external SD card and powering on holding the volume - key closest to the lock switch.

[Q] How to enter recovery mode using key combination?

I can use "adb reboot recovery" to enter TWRP 2.7 recovery mode, but I want to use key combination, please tell me how to that.

Hold Power + Vol Down > Wait until LG Logo pops up and release from both buttons > quickly hold Power + Vol Up + Vol Down again
It will pop up with some message about reset to factory settings, but it's all a bluff.
Hit Power x3 times to confirm and you'll get to TWRP recovery

Thanks, it works.
actually I enter this factory reset mode before, but i just don't know it a "fake".

so will this erase all data or not?

That will depend on whether you've installed TWRP or not.
If you've still got the original recovery it will wipe it like it says it will, if you've got a custom recovery it will take you to it.
The standard recovery isn't a recovery like you're expecting it to be, if just has a way of resetting things to default without allowing you to do anything extra. OEM don't like giving people options but want a way to reset to defaults that the customer can use before needing to return a faulty unit which might not be faulty. If that makes sense.

From what I can tell, it's not a "bluff". It seems that the stock recovery partition would just automatically do a factory reset, so it warns you before booting the recovery partition. Seeing as you're non-stock, it just boots into TWRP/CWM. It's a valid warning that's simply set up in a weird way.

You don't.
We'll you might be able to but you're going about it the wrong way.
First you need to find the right forum for your device, then you read, followed by more reading.
At some point you've hopefully discovered that you should have done all this reading before you reset your device.
Also before pressing the post button on your next post, read it first to make sure it makes sense.

Thank you very much, I tried other combinations found on some web pages that failed. This one worked!

Install LG software on your computer first. Then with the tablet completely off, hold VolUp and plug the tablet into the computer. That will enter LG download mode. Use the LG software on your PC to install the latest firmware available for your device. From there you can use the guides on this forum to go custom if you so desire.

[SOLVED] How do I boot into stock recovery?

From a full power off, how do I boot into stock recovery? I've tried multiple button configurations and none work.
EDIT:
I called T-Mobile and they said:
1. Power off
2. Press and hold the Vol - and Power button until the LG boot screen appears.
3. Release the Power button ONLY. Do not release the Vol - button.
4. After 1 second, press and hold the power button again. You should see the white recovery screen.
Use the Vol+/- to navigate and Power to select.

This brought up a Factory data reset menu on my H815.

Brings up factory reset on T-mo version H-811

That is the LG factory recovery.

thank you this worked

With a Verizon model, I had to keep holding both Power and Vol - until the recovery screen appeared. If I released and then re-held Power, as described above, it did not work.

When I hold down power and vol down, it boots to an IMEI display screen. It shows a long barcode. Can't get to recovery with the hold, release and hold down again the power and volume down buttons. Frustrating.

I love you so much right now. It boots into what appears to look like a default LG G4 factory reset page. For me, i clicked reset, and then yes, and surprisingly it brought me to where i wanted to go. TWRP Recovery.

THANK YOU!!!

The difference was that you have twrp recovery and he didn't. The question pops for both, but for those that have the original recovery it will do the factory reset.

I love you!
Your comment just saved me from doing a complete factory reset!
I never clicked "Yes" in the Factory Reset phone option because I thought it would do just that. Instead it took me to TWRP!!

And I get a factory reset as well on my H811, even though TWRP was already installed and working on the recovery partition.
Something else funny going on, the OS seems to kill TWRP after the next one or two boots tho. Maybe I need to set the TWRP option to allow change of the system partition to read/write? (Since apparently it writes something there that prevents the OS from killing the custom recovery after it's been installed)

I've learned a lot with LG phones over the past few weeks.
The biggest thing is.. when you first flash over TWRP, you HAVE to reboot into recovery before you try rebooting the system, or else the bootloader will overwrite the TWRP install and replace it with the factory recovery.img. (You probably already know this.) To make sure it boots into TWRP first, since fastboot doesn't have a "reboot-recovery" command.. I just pull the battery then do the button combination to boot directly into TWRP. Doing this allowed me to say "YES" to the question "Do you want to factory reset the phone".
I don't know how many times I've wiped my phone because of this:
1. flash TWRP.
2. reboots (tries to hold the finger combo but failed - and didn't know it)
3. gets asked question - "do you want to factory reset the phone"
4. I hit YES expecting it to take me to TWRP - but instead it wipes the phone and puts stock recovery back on.
Just do this:
1. flash TWRP.
2. PULL THE BATTERY
3. Use finger combo to boot recovery.
4. When asked "do you want to factory reset the phone" - hit YES
5. TWRP boots in like 5 seconds.
This has worked now for my G4 and my V10 since they both have this issue. The V20 however does not (my current phone) - so hopefully LG is done with this crap!!
Good luck!

What was happening on my H811 was that it was either corrupting the recovery partition afterwards or just invalidating it or something because instead of getting back the stock recovery, I'd get the scary "broken robot" screen when trying to boot into recovery.

The technique I've learned to appreciate (which apparently is a new thing, and is now the suggested method for installing via fastboot according to the twrp.me website) is to load a copy of TWRP into RAM to do the flashing and rebooting. ("fastboot boot [TWRP_IMAGE_NAME]")
I try to avoid battery pulls as much as possible but I have never relied on them on a phone the way I have done over the last week (just had my G4 for about a week now) due to these funky mechanisms that LG has for getting into recovery/bootloader/download mode.

TBH I am fearful of even trying it now. (Especially since I just read about how a nandroid backup done from TWRP doesn't backup anything on the /data partition, either.. )
Which makes me even more appreciative of LineageOS's "advanced reboot" power button menu. :good:
One of the problems in my view with this LG system is that it can be very difficult to reliably press both the power and volume at the same time on this phone due to it's unusual placement of those buttons. Much harder than on a phone with those buttons on opposite sites of the device. Not to mention this silly "press both these, then release one, then 1s later press that one again" stuff.
And due to the way they designed these sequences, which among other things often have no way to easily escape them (can you imagine having this on a phone with a non-removable battery?? ), but worse, have defaults that progress to another state without any user interaction (because of the limitations of this control logic - eg, if you boot to bootloader but can't escape and don't do anything in 2 minutes, the device automatically reboots), I personally have to wonder if this doesn't make a significant contribution to the infamous bootloop issues that lots of people are having with recent LG's like the G4, G5, V20, etc.
