Hello,
I tried to update the radio and the SPL version on my Tattoo. Everything went fine until I had to reboot my phone. It shut down alright, but it never powered on again.
These are the following problems I am having with my Tattoo at the moment:
Cannot power on phone.
Cannot boot into recovery mode.
Cannot boot into FastBoot.
When I connect it to my computer via USB, nothing happens.
The only thing that it's responding to is when I connect my it to my charger.
Does anyone have a solution or is my phone dead forever?
Thanks ahead!
bump? anyone?
Send it back to HTC. If anyone can do anything about it they can. There's nothing else you can do. Sorry
boo.. that sucks..
Well, thanks anyway
Ehm, I don't want to post a New Thread so I'm gonna ask here:
Does anyone have the pinout for the Tattoo?
Take a look at this. I guess they fix such things (but you never know if they just are after your money. http://www.ort-jtag.com/index.php
Yeah I saw that already. Also, there is a file name Tattoo Jtag on their website in the Support section. However, to access that section you have to enter your products serial number (which is I'm guessing the phone's serial number). I have tried several serial numbers (including mine) and all of them were 'invalid' so I never checked the files out.
Also, they only have one thing in the shop which is a kit and it costs $330 so no thanks
I have a similar problem, I would like to share my knowledge although I must be completely out of way.
My experience is based on the BeagleBoard and Angstrom so I really don't know the HTC HW and Android at all...
- The device boots from an xloader that instructs the device how to proceed with the boot
- the bootloader takes place (great u-boot in the beagleboard ?? in the HTC phone) the bootloader allows for ROM or kernel+rootfs flashing and much more
- now the kernel is loaded.....
User mode applications do not allow to have access to the memory area where xloader and u-boot lie so they should be safe all the time to allow for device reflashing.
So we should have access to the device via bootloader anytime if we knew how... maybe somebody can help us further.

Same here...Exact same issue...No Recovery mode...No USB Connectivity, Screen turns on but is blank, alhough I did see Tattoo popping up initially but not any more...All I can see is the LCD back light turns on...Battery does charge...Also when I try to enter Recovery mode screen keeps blinking as if it is trying to restart again and again...Someone help
similar problem here, but i get absolutely no response from the phone, it doesn't even recognize the charger. do i just throw it away and buy a decent one or is there a solution?
Sparky the only way for now to fix that click is to bring it to some service point that have that ort jtag, because only way to fix that is to writte new boot sector on phone . Im sure that i know at least 2 services that have ort jtag in Novi Sad . Look for marvel *Miroslav in Ns, or send me private message
same thing happened to me
just this morning, and in desperation I tried hard to remove the batt cover (prob pressed some of buttons, I felt a jerk and ho it was back in amon ra`s recovery, nect time I just removed the battery waited for 30 secs, then press off&home and hold it till recovery came back) but for good half hour NO REACTIONS , ABSOLUTE BRICK, nothing when I put the usb in PC or in socket, dead screen, no sounds and no reaction to ANY combination of keypress. I guess you could call me lucky (in last few days I flashed at least 3 versions of froyo roms, this afternoon I bought =8GB class4 Kingston, formated it in PC FAT32 default size, copied EVE. from my 2gig rom then just turned it down (yes I am brave) and put the 8gig in tattoo, it works like a charm (finger crossed it will continue)
So is there an available Jtag for the Tattoo yet?
I'm in the same situation. No recovery no fast boot, Damm!
I`ve update psfreedom with psgroove_hermes_v4 zip file then my tattoo reboot and now I only get the Tatto title screen but nothing happends.
Somebody have clue to give back life my phone.
Thanks!
if you can get to the title screen, that means you can connect it to your pc via USB and recover from a backup (I hope you made one)
Hello, I connect my tattoo to my pc, but usb connection is not available yet.
Is There is a way to activate usb when my phone blocks in tattoo logo??
Thanks for reply.

You have to enter in fastboot.
Hold volume down and turn on phone.

Sorry but as i said before, I can't access to recovery menu neither fast boot menu.
I bought an Acer a500 tablet a few days ago not knowing how broken it is.
After loads of research and attempting different techniques I still haven't had any progress.
The software issue:
When booting up the tablet, it goes to the black screen with "android system" at the top and power off/ shutting down in the middle of the screen.
Fixes I've tried:
1.
Since I don't know anything about what operating system is on this tablet, I have been blindly flashing different "stock" (from Vache) versions of HC.
--The android logo with gears shows up, the green bar loads but freezes when it gets 1 cm away from finishing.
--After turning off the tablet and booting it up again, "updating bootloader shows up on the upper left hand corner of the screen. Then a message pops up saying "apk installer: all pre processes complete". Then it returns to the black screen.
2.
The tablet will not go into apx mode (using the reset botton at the bottom).---Fixed. I didn't execute the steps properly. Apx mode works fine.
3.
I plugged the tablet into an older windows laptop and the computer could not install the correct drivers to sync with the tablet. Again also my lack of knowledge. I installed drivers from Acer.com
4.
These two guides seem to be exactly what my problem is but I can't seem to make sense of them:
http://forum.xda-developers.com/showthread.php?p=24531880#post24531880
http://forum.xda-developers.com/showthread.php?t=1572622
This is as far as I've gotten.
Other complications:
--The battery is dead. I have to use it while plugged in by the charger.
--Most of the thread that I have looked at use Megaupload as the source of downloading their files.
--The original owner of the tablet will not help me out. As I stated before, I don't know what version android OS was on here before it was bricked and on top of that the original owner won't answer my questions. As far as I know though, this tablet is not rooted or has anything "non-OEM" installed in it. The story goes that this tablet was bricked when the owner tried to "update" it. Before that, it was functioning perfectly.
-----It looks like Darvis is having the same issue and frustrations I'm having but reading his threads makes me think that this tablet is a dead end.

First off......I hope u didn't pay much for the tablet.
Secondly the guide above looks pretty straight forward but maybe this is one of the ones that has files at megaupload?
I know that the ra recovery and timmydean's files are accessible as I have downloaded both of them.
Maybe someone who has done this previously will chime in and get you the other file if it is indeed unreachable.

I would suggest trying to connect the tab to a Windows 7 PC after installing the USB drivers from ACER. Then check if your device appears in the device manager. As long as you have its UID you can flash the tab from the PC with one of the EUU tools - check my signature on "how to revert to 3.0.1" or TimmyDean's thread which offers an EUU with rooted HC 3.2.1 (it's linked in my thread as well).
How exactly did you try to get into APX mode?
p.s. I have the EUU files if you can't access them from the threads links. I can send them to you.
getting into apx mode
When I perform the steps (hold reset + power for 3 secs then release power); the tablet turns on as it usually does. It goes to the Acer screen, then android and back to the black home screen. My computer responds by saying that it is "installing drivers" but it "fails to install drivers". At the same time I have the DND.exe open and it does not recognize my tablet.
I'm trying to follow the instructions from the root 3.2.1 v4 file.
I can't perform the first step where it instructs me to turn on Usb debugging. The problem is that I can't open the settings by clicking the clock. Nothing happens.
I realize that one complication of my tab is that it will not charge. The battery power is below 15% so none of these fixes might not be effective for me. That might be the ultimate problem?
CyaN1de-
I paid $100 for the tablet. As of this moment I feel like I paid too much.
Thank you both for you quick replies. I have to say that most of the problems that I'm having is because of my lack of experience but I'm learning. I hope I fix this tab soon.
if this dont fix it, i'll give you what you paid for it;0
someone posted a while back that a hard reset fixed the android systems screen error
not sure where you're at now but no harm in trying it
Try using hard reset:
1) Turn off your tablet,
2) Rotation lock s to your left;
3) Press Vol+ (which is next to rotation lock) and power on simultaneously
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.
Thanks for the suggestion but I didn't accomplish anything by hard resetting it. I've done this many times and nothing has changed.
I haven't given up on unbricking this tablet yet and even though it's frustrating I'm learning from the process. If I decide to sell it, I'll contact you Dibb.

i've seen the 2 methods u described but i've not seen anyone else have success with it apart from the OP'ers - seems OTT to me but hey if it works for ya...
I've used timmydeans method ALOT on HC it never failed to work and that includes reverting back to HC from ICS - if it doesnt work for your issue then id be tempted to use blackthund3rs APXFlash Tool and civato's HC_ICS_Bootloader zip to flash a new bootloader and rom package on yr tab - but for the moment we'll run with td'sv4 - if drivers fail to install then believe me, its a good sign
try this:
I know you-ve probly done it but u need to do it again:
reboot everything, then reinstall acer drivers (yeh i know)
fire up ya tab but dont connect to yr pc just yet -as you said you
doubt usb debugging in enabled so we'll try another way around it
run the prgb20.exe it will scan for the new image but not find it becos youre disconnected...thats good....
after maybe 5 -7 minutes of scanning for the new image - it will show a
window "cannot detect yr iconia tab"
and instructions for getting into apx mode - go ahead connect usb put the tab into apx BUT don't click next until....
the drivers will try to install, dont let windows search but let me choose
(off memory) choose device and adb or android ph should show up here
the acer boot/recovery drivers should install...maybe even under USB Controllers
once they do and only when they do click next to put tab into:
acer download mode.......
as i said this is worth a go,,,,how about the update.zip have u tried that.....
else the only other way i know is apx flash....ya still need to get into apx
mode and if u cant then ???? sometimes youll try something over and over
and then out of the blue it will work...you'll swear you never did anything different , it jsut worked this time.....
hope you find some joy
Thanks Dibb for your words of wisdom. I've put it aside for now but I'm going to pick it up in the morning.
As addition to what dibb_nz said - Windows 7 would do the trick - I'm almost 100% sure you'll be able to connect in APX mode with the drivers properly installed. Then use one of the EUUs.
Drained battery really looks like the ultimate problem now because as far as I know you cannot charge the tab in APX mode - haven't tried that. Eventually I would suggest to crack the tab open, remove the battery and charge it somewhere - I don't know alternative ways but...may be another tab or you own charger with proper connector ...
http://www.youtube.com/watch?v=xvXihNIdQ1M
p.s. 15% power ... seems enough to flash through the PC...but who knows - don't waste them and get everything you need before starting the procedure.
no probs m8 hope u have better luck tomorrow
if u wanted to try the EC method i have those files if you want them
good luck m8

So I went through all these steps and the TD's V4 tool finishes updating the tab. But then it continues to the same black, android systems screen. And afterwards the tablet won't connect with the computer.
I am currently downloading the update.zip so i'm going to see if that will work.

do u get on yr tab the big 'PASS' in white leetters or "entering download mode" at all???
think we're beyond update.zip if EUU failed but you can try it -
you can get to apx which is a start - getting a new boot/recovery image on there is the main priority I think...as i posted earlier i've only ever seen a fix for this problem work for 2 people, so on new ground here....
But anyway check out the APXFlash method/walkthru in my sig....all the info is in there and the links to the required files ....do we know if you're on HC or ICS B/L????
I got the word pass; now using recovery mode to flash a rom.
not sure which bootloader I have.
I am using:
Acer_A500_7.006.01_COM_GEN2: http://vacheandroid.com/files/Acer_...1_COM_GEN2.zip
But after it says install from sdcard complete it also give me the message:
E: Can't mount/ dev/block/mm....
E: Can't mount Cache: recovery/log
E: can't mount open cache: recovery/log
E: Can't mount /dev/block/mm...

dibb_nz said:
yes if you're talking about the stock roms from vaches thread, you need the full rom package - you cant just use an 'update' package as they need a full rom to work properly....
for instance my original HC3.2.1 Stock build is 7.014.15_COM_GEN1
and theres no FULL Rom for 3.2.1, so i have to use the HC 3.2 FULL instead
.....Acer_A500_7.006.03_COM_GEN1.zip
Once flashed, thankfully I recieve the 2 small OTA Updates to get up to 3.2.1 again
Another couple of days the ICS OTA d/l'ed and installed with no probs....
is that clearer or am i making things worse????

I could never get mine into apx mode with the usb cable plugged in. So try that if you haven't. And it is literally hold reset, then press power, without letting up on the reset, release the power button after 3 seconds (use a watch or timer!) then one more second before you release the reset... It does work, but the timing has to be close. It must have a tenth of seconds or less tolerance. Very picky... I've done it on 2 different a500s so far and I am heading to do another tonight. If it doesn't work I'll be right back!!!

Crikey just as I finished typing "....land"
Back to more important matters..... whr u at m8????
None of the roms I've tried to flash go to completion. I'm stuck at trying to flash different roms from recovery mode. Not much luck with what I've tried but I'm going to try more before I give up.
Are there any particular roms I should try more than once?
Or why am I getting the "error" messages stated earlier?

recovery mode???
u need a new boot and recovery image on that thing
the HC EUU based flash arent working even tho u got a PASS on screen after TDv4
So HC based methods arent up to it. You need nvflash/fastboot.
We need ICS with the unlocked bootloader it has access to another level below where HC worked because HC b/l is and always has been locked down.
If ICS cant fix it, I have no idea what will and my offer to buy is off the table!!!!
check out civatos guide and ready yourself for nvflash via zip files in that post or blackthund3rs APXflash tool, with a complete tutorial for using it, all links in my sig.
good luck
Just to chime in with a tip on getting google drivers to work.
When getting any device not recognized, or driver error, generally I go into windows device manager, select the unknown or offending device, update driver, only I choose which driver to use, and ignore the error message where it says "may not be compatible with your device", and use it anyhow.
I get that occassionally when swapping back and forth between devices.
Also, battery not charging and display errors, are usually a sign of EC Power control. So you were on the right track about that. Once you get a rom up and running, if the batt don't charge, then there are some EC flash's you can do from CWM.
Back at it again using BT's nvflash tool. And tablet is still bricked.
I've tried a few different bundles and none allow me to operate the tablet. Everything goes smoothly and I get "pass" at the end of the process. When I go to reboot the tablet, it gets stuck at the black start up screen.
Found another lead: http://forum.xda-developers.com/showthread.php?t=1579490
Sounds like he was in the same situation as I am but has a bit more skills and knowledge dealing with problem solving.
You say you were able to flash roms. So apparently recovery is working OK. Have you tried flashing civato's flexreaper? It has code that will detect whether you bootloader is HC or ICS. You may just be flashing a rom that doesn't match your bootloader... I know I'm jumping into the middle of this, but it's just a thought.
Also, when you did the hardware reset with the rotation lock switch did you get the confirmation that it was, in fact, being wiped?
Failing all that, I'd be willing to take it off your hands for spare parts...

Hi guys,
after three days of reading and reading and many hands on - thank u all for all the usefull posts here - i need a definitely answer:
- is it possible to grab the acer a500 cpuid under APX Mode or not?
Scenary:
- tablet prompts every day for an update. My friend at last accepted it and then the reboot came and then some problems like restarting, crashes, etc. (I suppose a simple hard reset would fix it and he'd have a clean and workfull update. But he took to a assistence shop near his home and as i can figure it out they tried to flash it instead cos stuck in android after acer splash. And if tried to go into recovery mode only a layed down droid with that red exclamation.
- in my turn first tried to grab cpuid as i read here - thank u all - but all i got 0123456789ABCDEF. Then tried to flash with an update.zip grabbed from some rom version i cant remember after such many readings... No longer, sorry - and after updating completely the TABLET CONFIGURING screen comes out then reboots and BOOT VERIFIED FAILED. I tried also others update.zip but this one is the only one wich can "works". All the others one i tried stop around 33% and the droid lays down again.
That´s why i need an answer to my question cos i think it´s the only way to have a succesfull flashing via APX mode. Am right?
After so much brain stormings i have seen around here about this issue will someone still try to gimme a help?
Thank u all in advance.
Rgds,
If the device is booting into APX mode you should just need to do a read of 8 bytes, this should give you the UID.
I posted some C code for doing this with libusb before.
And this should be posted in Q&A.
I have followed many threads but cannot find a working solution. I will outline what I have done as briefly as possible.
While streaming to TV with HDMI, the screen switched to the android robot on his back with red triangle and "!".
I put Acer_A500_1.031.00_WW_GEN1 on a SD and tried to reboot, showed robot working and then on back with "!" again.
Put in fastboot and used ADB command lines to try to put Thor recovery on, stated device locked on screen.
Entered cmd to unlock, got positive response, tried thor again, same result.
powered down, re-installed asus drivers, connected it did not connect as APX so rolled back drivers and was able to connect as APX.
Ran AFTEROTA, cannot find device
Ran Blackthund3r manager, stated a500 connected in APX mode, but when trying to get Serial program runs but returns nothing. And when trying to get logs returns "no device found" but at the bottom still shows connected in APX Mode.
I am unable to get the CPUID and the device does not boot for me to put in USB development mode so I am unsure where to go from here. Again I have spent several hours following everystep in multiple threads and I keep getting stuck. Any help in helping me return my A500 to working condition would be great. Also, before crash I was running ICS OTA stock.
v/r
i also have the same problem & also try almost everything of what you did but mine is not rooted a virgin tablet running on latest ics . i can also get into apx mode but cannot generate the uid.. i know there is a solution to this using ubuntu but i dunno how to use ubuntu or libusb or visualc+ as what it stated to generate the uid & was hoping that some1 might try to make a step by step thread in using linux or winusb in windows

heck you are in a bit of a pickle m8!!!
i think you can only use an update.zip (no cpuid required)
have a look at jdgM3NTL's thread " revert to factory stock the easy way" http://forum.xda-developers.com/showthread.php?t=1839313
IF this doesnt work you'll be in for the long haul - you will need to use linux as that is the only other way to get yr cpuid - have you checked out the cpuid thread (u only need to read the OP)
there are at least 7 different methods for retrieving yr cpuid, u might try usbdeview

Thank you for your reply.
In response to some of your questions. Yes I meant to type Acer and not Asus, I do in fact own the Acer A500.
About my initial attempt to flash the stock ROM, I never had an unlocked bootloader, before the tablet was bricked I was running Stock ICS OTA and had never done any modifications.
I tried using USBDeview but the serial number is blank. It looks like I will have to try the Linux method. Again thank you for your help.

And this is WHY IM DONE following or using XDA THREADS. Most of the time someone experienced helps for a bit than leaves people hanging. I just unbricked my a500 when no one answered for my help. This guy here responded back and no o e help him. Hit and miss here. Go to another forum if you canr find your solution aleeady poSted. Cause if you reply or start NEW THREAD, no answer 90% time. Mine was bricked And rooted. Stuck on acer screen. Tried everything I could. No answers fron this sites threads. But I did it on my own, simple fix for apparent hard brick a500, but it was not really hard bricked. All symptons showed hard bricked. You wanna know what really fixed my tab without changing main board...?? Hint.. xbox red ring.....xda, you suck, no support for newbies here. Out. Unsubscribed..deuces. .
Hey guys, looking for some assistance here as I am at a complete loss.
Decided tonight to root my 4.2.2 Nexus 10 using the Nexus Rootkit v1.6.3 and the aid of a YouTube video. All went swimmingly up until the TWRP wipe. The video I followed failed the wipe attempt and the guy showed how to get the N10 out of the bootloop and do a 'wipe data/factory reset' via Recovery Mode in the Bootloader and then restart.
Problem is, my wipe never failed like his did in the video (great I thought!) and so I restarted after that and now I find my N10 booting up to the Google Logo (with the padlock at the bottom) and it just sits there. Doesn't even get to the 'X' logo which should come after.
I've tried a few things including the manual wipe data/factory reset from the bootloader and restart but everytime it gets stuck at the Google Logo. I am also now at the point where my N10 doesn't show in Device Manager as it did before. It now shows under 'Portable Devices' as a 'MTP USB Device'.
I am really at a loss here and searching various solutions is just confusing me even more and would appreciate it if someone could help me out, even just getting back to stock for now. That's if it isn't goosed?
Thanks in advance
Have you tried using a different usb port on the PC, and rebooting the PC?

I have yeah. Left my PC off overnight and went back to it again this morning and same issue.
Plug it into the PC (this time using a USB port on the back) and it initially comes up 'installing device driver software' quickly followed by 'device driver software was not installed successfully', quickly followed by 'installing device driver software' again and that's when it shows up in Device Manager as 'MTP USB Device' under Portable Devices, whereas before during the root attempt it was show as 'Nexus 10'.
When I first read the subject line I thought it was "another one of these" where OP hadn't searched on the existing boards. But when I read OP I see you did try "the usual suggestions". Hoping a more seasoned pro jumps in here to help...
I can say that on the handful of "really bad" posts like this that I've seen they usually end with the person saying something like "well I don't know what happened I just kept trying all the power button / charge recommendations and finally it worked" - so don't underestimate the effectiveness of repeatedly trying it like a mad man!
Some random suggestions I have that may help:
-Can you leave it on, on the Google screen, to where the battery 100% drains, maybe this could act as a "battery pull"
-Try a different USB cord
-Try rebooting it via the power buttons while the device is plugged into the wall charger
-Download the Android SDK, then use its "update manager" to update its USB drivers to today's definitions
-Try another PC
Good luck!
Thanks for the suggestions bigmatty, I'll certainly give them a go when I get in later.
I think my biggest concern is that there doesn't seem to be any OS on it, possibly to do with the wipe during TWRP and then I rebooted - was I supposed to reboot at that stage? That's where I got into this loop. And now it doesn't detect it as 'Nexus 10' in my Device Manager on my main PC. Only this MTP USB Device - sometimes showing a conflict warning triangle, sometimes not and no longer showing as a storage device in My Computer.
I did connect it to my Netbook (Running XP) earlier and it detected it as an 'Android Device' under Other Devices in Device Manager. Tried installing it with the naked drivers on the Android SDK and it now lists it under 'Android Device' in my Netbook's Device Manager as a 'ADB Device' (I think, would need to double check as I'm not on it at the moment.)
I just want to find some way of getting it back to factory settings and stock OS if possible and then take it from there again. Don't fancy at £319 paperweight! I'm usually alright with these things too.
Thanks again (And if anybody else has any other input in the meantime I would be grateful - I'll try anything at this stage!)
I'd say its a good thing that the PC exhibits varying behavior - because that means there is still hope!
It really boils down to if you can open an adb.exe shell to the device. Can you? It would not be when its showing as MTP but it would be when its showing as adb in Device Manager. If you can then here is a thread where I explain (pretty good, I think) how to get back to stock:

Now I realize Im not clear on a second avenue - can you still get into TWRP?

Can't really get into much on the Tablet itself. It boots up, gets to the Google logo (with the padlock symbol at the bottom suggest it has been partially rooted (?)). I can get into the Bootloader by holding down the Power + 2 vol buttons. Once in the Bootloader I have the options of Start/Power Off/Recovery Mode/Restart Bootloader.
When I go into Recovery Mode I can get access to the blue menu where I get the options to restart/something about adb/wipe data/factory reset/delete cache partition (paraphrasing here).
Don't know how many times I've tried the wipe data/factory reset option and reboot but always get sent back to the same loop.
I'll give you're other idea a shot as well later. Thanks again.

bigmatty, you the man!
Managed to get back to factory stock following yours and styckx's guidelines. Couple of little teething problems along the way but nothing I couldn't get around.
I now have a fully functioning Tablet again and I thank you for it.
Might give the Rooting a miss for now but if I come back around to the idea I'll be sure to follow the guides on here this time instead.
Thanks a bunch again for taking your time out to reply to my thread and get me back up and running again. :good:
