[Q] non-rooted MT3GS stuck in boot loop

Tried the offical froyo update and it got my phone stuck in bootloop...
I was not planning on rooting this device but i will, if i have to, to fix it. I see there are many different ways to root it so i was hoping someone, more familiar with the device, could send me in the right direction to root this phone.
Basically, the device wont boot into android.
i can access the HBoot.
Options:
Fastboot
Recovery
Clear Storage
Simlock
Is there anyway to flash a new rom onto this without being able to boot into the OS?
what do you think? thanks for any help!

Well, after a few hours of messing around with this... I finally posted the [Q] to yall looking for help, then figured it out a few minutes later!
If anyone has this problem in the future:
1. pull battery
2. replace battery and boot device WHILE HOLDING volume down. This will access "Hboot"
3. use the volume down button to hover over option 3 Clear storage
4. select using the power button
5. hit yes using volume up
enjoy your working device with official froyo update.
Disclaimer: you may or may not enjoy official update

That's how it always goes, you get frustrated and desperate enough to ask a question, after hours of trying everything you can think of, reading countless posts, then two minutes after posting your question, the answer falls in your lap. Can't tell you how many times the same has happened to me lol

Cyanogen Mod stuck at splash screen after flashing

Just a quick post to all of you who are having this issue. This may be a repost, but I'll give the solution anyway.
If you have this issue after flashing Cyanogen Mod 6.1 or 7 just perform these simple steps to correct it.
First (if you haven't already), remove your battery, it won't hurt anything.
Second, replace the battery, hold down the volume down bottom and press the power button once.
(You may release the volume button once the bootloader screen appears)
Third, wait until it checks the MicroSD card for an update file, then using the volume down button, highlight "Clear Storage" and hit the power button once.
Once it reboots Cyanogen should load right up. Hope this helps someone!

Just wanted to say I believe its volume down + power to access the bootloader. Hope this helps.

Your absolutely correct! That was my mistake. Thanks for the warning.

No problem. Good info to know though. I've never really had any problems with CM7 but I've wondering if clearing data in bootloader as opposed to recovery might work as well.

I know a lot of people have had this problem. But not all, I guess its subjective.
But I have definitely had this problem, both with version 6.1 and with 7.
I love the Cyanogen Mod! What a difference that makes with Android.
The main reason I switched was because I wanted ad-hoc network options.
I soon realized it was so much more than that though!

I have followed these instructions but it either takes me back to the HTC Incredible splash screen (and hangs again) or to a Clockwork menu (black background with orange text). Either way my Incredible is still not booting back up. Help?

I'll be glad to help you. I don't have an Incredible anymore, but this is fairly universal.
Okay, so what have you done so far, give me the steps you used to flash CM.
Also what version of Clockwork and Cyanogen Mod are you using?

Do i need to wipe before flashing rom?
I have tried miui and CM7 both and after it gets down it gets stuck running the bootloader image. I just got the phone rooted and want to try a rom out, but i am having troubles...

Is good Rom cyanogen?,have htc sense 3.5?

Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

Key integral information would be what ROM and software you're using now. Some launchers have extra settings, that can inhibit the Android security settings if they conflict.
Also, you might find the answer by posting to the Thread where you've gotten your custom ROM...you might even find the answer (drum roll & dramatic pause for effect) searching.

currently i am using original firmware 2.3.6 from tmobile;
i restore by using: SGH-T989_TMB_1_T989UVKL1_CL799405_REV00
i will try to post my question there too

and did you make sure you didn't use titanium back up to remove or freeze something you shouldn't had? I accidentally did that b4 and caused something to not work until I defrosted it

[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] Welcome screen and Lock screen missing after flashing STOCK ROM

Hey! Need some help if possible. I was messing around with my Captivate Glide. Tried to install some other ROM's but all of them made the phone lost the baseband and IMEI (EFS). I tried restoring the EFS using EFS Pro Tool, but my phone is not being recognized while on CM 11. I decided just to flash back to stock, using the I927UCLJ3_I927ATTLJ3_ATT (which was the only ROM that was showing up the IMEI and got connectivity).
Something that's been bugging me is that after doing all this, the phone boots normally, but there was no welcome screen, it just jumped straight to the main menu without asking for the google account. On top of that, the power button no longer shows the options it did before (reboot, power off). With one press it powers off the screen. If I press it for 2 seconds the phone turns off. There's no even a lock screen on my phone. I've been unable to set lock screen security options. Any options that I select are useless. They do show up under settings, but they don't do anything.
I've been trying everything to get this options back, but I'm not sure how to. I've already flashed my phone to stock, tried with other ROMS, using the same I927ATTLJ3 as reference (since it's the only one that shows the IMEI for me) but nothing. It was showing on CM11 though, all power options where working, as well as the lock screen options. I'm desperate now.
Any help on this?

Have you factory reset your phone? That described things can happen especially when switching between ROMs
