Glad you guys are working on a solution for this, I've been pulling my hair on this for the past 2 months.
[Acer Iconia A500] blackthund3r:
That's very useful thank you very much. I'll look at this ASAP
[Acer Iconia A500] zozo10k:
I was pulling my hair for last ten days, because of the same problem.

And, finally I got it working by doing rollback to HC, and flashing bootloader form there... It worked flawless!

Check THIS POST for more info.
[Acer Iconia A500] kylereid:
Thanks! Going at it now!

Is there anyway you could upload the "EUU from Timmydean of 3.2.1 V4", because deposit files keeps bailing on my download. i've got to 50mb and then it quits. have tried over a dozen times.

thanks.

Edit: Tried another dozen times. THe furthest I got was 24mb of 498mb....
[Acer Iconia A500] kylereid:
thanks for the link. got everything to work perfectly!
[Acer Iconia A500] zozo10k:
HC bootloader with TWRP cwm (touch cwm) is

ONLY

for flashing HC Roms.

You should choose any other bootloader if you are flashing ICS rom.

Tip: first copy some ICS rom to sdcard, than flash bootloader
[Acer Iconia A500] kylereid:
it's all good. thanks. flexreaper is great eh! just playing around with it now
[Acer Iconia A500] steokeogh:
Issue Resolved

Using the method outlined above the issue is now resolved for me aswell I have CWM install with ICS I have a working recovery and its all working fine. Also have undated the bootloader aswell

Thanks to everybody for the help
[Acer Iconia A500] dibb_nz:
yeh fixed me too...things are working well after the rollback and reflash and no funny 'glitches'

happaz!!
[Acer Iconia A500] ereinhart:

[Acer Iconia A500] sgregory111:
Can't get anything to flash - sits on uploading image

I have spent the better part of the last 2 days trying to get my new (refurbished) A500 to have a custom recovery so I can apply a "fix" that is suppose to help my GPS issues.

I was stock ICS after several software updates.

I used ICS Root 7 for Iconia Tab (I am on windows XP Pro)

That seemed to give me root, although I had to always mount R/W when I wanted to do anything.

I was never able to go into recovery. I would always get the dead droid icon with the exclamation mark above him.

I have tried (many many times) Afterota and a500apxflash. These seemed to have problems with the APX mode.

I discovered that my Acer tablet was using a Motorola Driver. I uninstalled all Moto drivers and re installed Acer USB drivers. This seemed to really help and now I get into the APX mode with icon. I thought I had the problem resolved. But now every program I try to use to flash just sits on flashing image message. I give it a good 40-45 minutes, more the first few times, and they never get further.

Thoughts? Suggestions? Please anyone that can help I will appreciate it.

Although I am a technical person this is not my area of expertise.
[Acer Iconia A500] dibb_nz:
How did you install a recovery?

You must be reasonably 'expert' to notice the moto drivers and replace them, good for u!!!

In the apxflash link in my sig is a step by step pictorial - if you take a look at it, you might be able to spot where the problem may be - and can u explain a bit more about the "flashing image" error u get, do u get the download apx mode writing on yr tab on the tab screen

the other thing is I've never been able to use nvflash to get into bootloader mode??? so I normally start with a500 manager which gets me into apx mode

then onto entering sbk into civ's nvflash to do the actual flashing...works for me!
[Acer Iconia A500] sgregory111:
Thanks for the interest and help with my "issues".

To answer your first question, I have not been able to flash recovery. I think that is what I am trying to do.

following through your log, everything works perfect up to the point where you say "On the PC things start going crazy". A couple of screens pop up, but then it sits on

Flashing Bootloader (EBT) stage two - uploading image...

It will sit there until I finally give up. Your log shows 4-5 minutes. I have waited 40 minutes. It works so well up to that point. I getting the loading screen on the tablet. AFTEROTA works fine, able to read SBK and other info off the tablet. But whenever I try to flash it hangs on me.

UPDATE: I have tried the manual flash and think I may have found something......

This was on the screen......

At least it gives me more to look at. Any thoughts?
[Acer Iconia A500] dibb_nz:
are u on hc bootloader?? if you are then hook yr tab to yr pc and before opening the flash tool run "adb devices" and tell me if it gives you an device ID, it it does then your drivers appear to be ok but just try running the acer driver setup again - install both sets of drivers again if you do not receive that device ID

i would also try a different 'package' i had this yesterday when flashing back to a recovery I've had installed before - it wouldnt flash at all, but another recovery did...so yeh try a different BL & recivery apex....

are u getting the white writing on your tab "entering apx mode bootloader " something like that????

when u rooted did u check the option to delete the "recovery.from.boot.p" file???

if u dont do this then your custom recovery gets overwritten every boot!! This is the normal meaning of the "dead android" - its the stock recovery

if you are positive your cpuid is correct and that you are flashing the correct pckage - then there isnt alot more I can help with - its a bit weird that none of the methods are working

You can try ARI acer recovery installer from the market and flash a reocvery that way

A hard reset (wipes ALL data) isn't gonna hurt either -
[Acer Iconia A500] sgregory111:
are u on hc bootloader? I don't know. I thought I was on ICS, but that is only because I think my tablet is on ICS. It started out as HC, but I did a bunch of OTA system updates and now it is (I assume) ICS. Does that make my bootloader ICS or HC since it started life as HC.

Build Number: Acer_AV041_A500_1.033.00_PA_CUS1

Android Version 4.0.3

Kernel 2.6.39.4+

Image Version: Acer_AC041_A500_RV05RC01_PA_CUS1

How do I run the flash tool ADB Devices?

I have installed the USB drivers many times now.

are u getting the white writing on your tab "entering apx mode bootloader " something like that???? I Sure Am!

when u rooted did u check the option to delete the "recovery.from.boot.p" file??? Yes I did

if you are positive your cpuid is correct(I don't know, can I test it?) and that you are flashing the correct pckage (I am not sure what package is correct. I am have tried both HC & ICS ones) - then there isnt alot more I can help with - its a bit weird that none of the methods are working. Don't give up on me yet!

You can try ARI acer recovery installer from the market and flash a reocvery that way, Will that work if I am ICS? Am I ICS?

A hard reset (wipes ALL data) isn't gonna hurt either -How do I do this? I would normally do this is recovery, I don't have one.

I have tested the SBK and they seem to work fine (using SBK-test)

Do you think I can roll back? I am worried I can't if I don't have a working recovery.

UPDATE: I think that after I got the Motorola drivers out of the issue my problem became those of the people who posted earlier in this thread. I think the general solution outlined for them was to roll back to HC and get a good recovery installed, then re install ICS.

I am just worried if I can still do that without what appears to be no recovery. Will study "instructions" on rolling back to HC. If anyone has a good link or instruction feel free to let me know. I think this is the next tact I should take.
[Acer Iconia A500] dibb_nz:
yep ics rom dont know about the b/l, do u have a working system? d/l acer recovery installer from the market that will tell you yr bootloader version

See Wheres my cpuid at link in my sig

the acer ones AND the adb ones - in first post of cpuid thread

sweet

its all in the cpuid thread but look for dmesg method and reboot yr tab before running it....

not until you're sorted:)

yep it'll work!!

manual hard reset:

1) Turn off your tablet,

2) Rotation lock to your left;

3) Press Vol+ (closest to rotation lock) and power on simultaneosly

4) As soon as the tablet vibrates you can release the power on button and you should start to switch rotation lock left and right till you see

Erasing Userdata...

Erasing Cache...

Vol+ is still pressed;

5) The tablet starts to format

6) Your tablet will be as clean as it can be.

yeh have a look at jazzyjames rollback thread for how to do that - just keep yr tab disconnected from yr pc UNTIL you are told to connect it -

yeh you'll be ok using the EUU to rollback with in jj thread - no recovery needed for that.....keep us posted!!!!
[Acer Iconia A500] sgregory111:
My system is working. I am doing this to improve GPS performance and because I suppose I am an old geek.

Bootloader Version is 0.03.12-ICS. I am guessing this a a locked bootloader and may be the cause of some of my recovery issues.

Checked my CPUID and it matches what I am getting form afterota tool. I never have entered my CPUID into a program, only the SBK keys.

I think I have the adb drivers now. I downloaded the Android SDK. ARI recovery indicates I need an unlocked bootloader to make recovery work. Guess that is what I will try next instead of a rollback.

ICS seems to be working fine except a lot of apps only seem to work in portrait mode.
[Acer Iconia A500] dibb_nz:
yah! another...errr... 'wiser' geek, the more the merrier:)

ok cool, make sure u have the adb drivers installed, then open a cmd prompt on that folder and whilst yr tab is connected to yr pc (and usb debugging is checked) type: adb devices

if u see a number there then the drivers are all ok and u should be good to go!

if no number is displayed, then they arent installed, so try again

I'd try civatos nvflash package for v6 BL and cwm 1.7 (2nd link in my sig) I think that combination has the least probs - get into apxmode first (i use a500 manager to do this)after u enter yr sbk - it should validate it by running the system information window it will show amongst other things your chip uid....

if u dont see this window then something is wrong, dont go any further until that is fixed...see thumbnail

hmmmm...guess it depends which apps you're using - mine are all pretty good, no probs
[Acer Iconia A500] sgregory111:
I assume adb drivers are OK!

---------- Post added at 09:46 PM ---------- Previous post was at 08:54 PM ----------

Maybe I need to give up, something I am not good at, but I can't get this to work. I don't think the software is ready yet. I think that is what they are talking about in post #12 & #13 or so of this thread. Then they started to talk way over my head. It seemed like there was more work to be done before this would work.

I definitely tried civatos nvflash package for v6 BL and cwm 1.7. Same results as before. I do get the system information that you attached in your thumbnail. When I am in manual mode I see the following:

It sure seems like this is my issue.

I really would like to get this to work. I would like to try some other ROMS and stuff that I know I need recovery for. But maybe Acer made it so that those of us who did OTA to ICS cant do it, at least until some developer works around there block.

I don't know, but I am getting frustrated.
[Acer Iconia A500] sgregory111:
I changed the batch file to remove the CLS so I could see what was flashing on the screen.

This seems very much like what is reported at http://xdaforums.com/showthread.php?t=1622425&page=36 Post#359.

It seems the solution is to roll back get unlocked bootloader installed then return to ICS. I just don't have the time right now. It seems like a lot of work and with some risk. Is there any other solution? Is this my best option?
[Acer Iconia A500] dibb_nz:
well, thats not looking very healthy.....can u still boot???

can u try a different choice just to rule out an issue with the recovery itself

we.re a wee bit limited to what we can do b/c of the locked BL you have...

but a downgrade is looking the more likely solution

you;re not in deep do do as u still have a working system, adb and yr cpuid so dont give up just yet:)

I OTA'ed to ICS without too many issues, but just for fun i tried out one of Official Acer stock pre rooted ICS roms from civato's thread.....m8 i couldnt believe the difference...exact same build and yet so much different and better - I'd originally had flexreaper before going back to HC and OTA

i'd suggest doing another hard reset, theres something screwy with the boot partition and im not sure flashing a rom will fix it....but try it first....
[Acer Iconia A500] sgregory111:
Hard reset did not work.

This sure seems exactly like the problem reported in http://xdaforums.com/show...622425&page=36 Post#359 and other posts earlier in this thread.
[Acer Iconia A500] Skrilax_CZ:
Partition table is bad bct.bin (for other partitioning). This is being resolved by the automatic tools atm.

Right now you have two ways: either use cygwin / linux to get your BCT, or use the "root 3.2.1 V4", that will completely wipe your tablet, but repatition it to the partition table that is supported by the tools.
[Acer Iconia A500] sgregory111:
Thanks for your post!

Let me make sure I understand what you are saying.

Your saying if I am patient and just wait a little the tools used to load boatloader will be updated to handle my bct.bin?

To use root 3.2.1 V4 I have to rollback to HC first, correct?

I like the idea of waiting, and then donating to the first developer that gets something to work. Which tools are being updated that I should keep an eye on?

Guys

I observed that there is a crack in the benzel of my sgs2. Benzel i mean The plastic lining that wraps around the front glass.

The crack is near the volume buttons.

How easy it is to replace this plastic strip ? Is it risky ?
[Galaxy S II Accessories] GuestK00450:
Pretty sure you mean bezel, not benzel.

You would probably have to replace the entire housing which is quite risky to do in my opinion. If you don't know what you are doing you could short the board or break something.
[Galaxy S II Accessories] TheSniperFan:
Happened to me too.

Is it really so bad that you need to replace it?
[Galaxy S II Accessories] DaPhinc:
Happend to me too. Seems like that part is very fragile.

I think the only way you can replace it is replacing the whole screen and touch panel.

After that one little crack and that mysterious burn mark right next to it (damn alcohol :p) i finally decided to buy a case ;)
[Galaxy S II Accessories] sachinaik:
Its not so bad. But there is an another minor crack on the exactly other side of the benzel where power button is present !

Is it because of overheat ? I use my phone while charging and battery temps are at 46 celcius when I do that.

I never dropped my phone.

If I go for a new benzel then will I have to pay for new screen too ? Is the benzel glued to the screen ?
[Galaxy S II Accessories] sachinaik:
Buying a case is not an option for me. I nvr dropped my phone. I use it very carefully , I love my sgs2.

Why would I have to replace screen also ?
[Galaxy S II Accessories] jpbl1976:
You can probably have it replaced at an official Samsung repair center. I'm pretty sure they carry one or two sets -- or can order one for you -- but it'll probably set you back a little.
[Galaxy S II Accessories] DaPhinc:
I am not sure about this. But looking at the screen replacement tutorial (http://xdaforums.com/showthread.php?t=1253969) it seems like screen+touchpanel+bezel is a single part. I guess it is somehow glued together. But again, that is just a guess.
[Galaxy S II Accessories] m2smoe:
just put a little glue in the crack
[Galaxy S II Accessories] sachinaik:
went to samsung service center.

They said they will replace the Glass panel, Pled screen and benzel.

Oh what the hell, I'll get a new Oled screen. Will go for SGS4 directly :)
[Galaxy S II Accessories] DaPhinc:
I guess it is not covered by warranty, is it? How much do they charge you for replacing it?
[Galaxy S II Accessories] sachinaik:
Approximate 6000Rs I.e, 120$
[Galaxy S II Accessories] Hanafubuki:
yeah I noticed a crack on my bezel above the volume button. You can kind of see it on the enclosed picture.
[Galaxy S II Accessories] the_chinaman:
I've got a crack in almost exactly the same place as the above pic, slightly closer to the top of the volume button.

Mine has been in an official flip case since day one and has never been dropped. I only noticed the crack when I looked after reading this thread (just like the plastic cover over the home button thread!).

I wouldn't have noticed the crack because of the case. So, is this a design fault? Is it heat or flex that is causing the crack?
[Galaxy S II Accessories] sachinaik:
The benzel is the most fragile part I think.

I must be because of heat. As the processor, gpu and antenna are near camera module. The top portion gets a lot hotter when accessing 3G.

On top of that if any pressure you put on it going to worsen it. Putting it in a tight jeans and then when u try to remove it out of pocket, u tend to grab the benzel a lot.

All in all, I would go for a metal/polycorbonate benzel in my next phone. That disqualifies SGS3.

Obviously I dont want to pay a hell lot of amount just to get a thin plastic strip (benzel) to be replaced.

Just because samsung did stupid move to glue them together and chose a cheap plastic for benzel I now have to pay a lot.

Waiting for HTC One XL(unibody) with S4 chipset. At least it would come for 3 yrs rather than breaking within 11 Months.

End of rant. Sh**ty cheap plastic Samsung.
[Galaxy S II Accessories] Huck33:
same issue for me

i discovered that few weeks after buying the device

i kept the device with that crack but i worried about it

"happy" to see that i'm not the only one
[Galaxy S II Accessories] Pepski:
Incredible! Saw this thread and wondered what the hell a 'benzel' was. After reading that it had happened to more people, I just checked my phone and it has the same crack. :D

Had never noticed this until now. Fortunately mine is a black phone, so not as noticeable as the white.

also the bezel scratches easy is there any point in replacing it when you could pay to have it fixed then drop the phone or scratch it against something??

wear marks are never good to see but they do happend
[Galaxy S II Accessories] sachinaik:
This isn't a crack on the benzel. Unrelated to this thread.
[Galaxy S II Accessories] rustyguy:
I attpted to replace my bezel recently. Everything is a breeze except for when you remove the screen. It eventually worked however I used a paint stripper to heat up the glue and overheated the screen. As a result the oled screen began to separate from the glass at the top of my screen.

The bezel is a cheep replacement, but in my opinion, not worth the risk. Getting the screen off the old one is a huge pain while trying not to damage it.
[Galaxy S II Accessories] sachinaik:
Seem to me that all SGS2 benzel is bound to crack within an year.

Nobody noticing it. Because of back cover or protecting leather pouch etc
