[Q] Tattoo Bricked

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)

I used to love your ROMs for my old Touch HD.. good to see you now have a Galaxy S!
Not so sure from your posts above what method you have tried. When are you trying to connect Odin? You need to be in Download Mode first, fire up Odin, then connect your phone...
Is this what you are doing?
Also, which version of Odin you using? In Win7 you may need to right click and run as administrator?

The best way is to look on the odin how to here in forum

Brother, use Odin3 v1.7 from my signature & see if it detects? A lot of guys have recovered their phones using 1.7. trust me.

pull the battery
wait a few seconds
put the battery back in
hold vol-down + power + home
You should get into download mode
connect the phone physically to the pc
flash a ROM or a kernel or whatever you desire
I wish you good luck^^

Close any kies process running in background and try again

The jig most likely wont work if the phone is completely dead, you could try a hairdryer it seems to work sometimes. Otherwise its back to samsung.

[GUIDE] How to unbrick Acer Iconia A500

I just got from a friend an Acer Iconia a500 he says that is bricked.
I tried this method: http://forum.xda-developers.com/showthread.php?t=1572622
But I can't continue because I don't have ADB access, what should I do?.
Thanks for all and God bless you.
EDIT:
I got everything to using the secret APX mode, but now is still everything the same the Android System is still there and not charging and not touchscreen...
Go to the bottom to see how I solved this lol...
Click to expand...
Click to collapse
If your tablet Iconia 500 (ONLY ACER ICONIA A500) went crazy, and present the next symptoms (Yes it has flu...):
-flu
-Android System icon
-Doesn't want to charge (20% / 15% 12%).
-TouchScreen is not responsive.
-Always when you turn it on says Shutting down and never shuts down.
-In case you're using ICS shuts down immediately without even make you see.​
The solution is the next!:
1. Download this file: http://www.4shared.com/archive/zyP91E0C/root-321-V4.html (This is the file to put recovery in case that you don't have it).
2. Extract all the files in any folder, it doesn't matter where you put it.
3. Go to Image Folder and rename the recovery to: anyname.img.
4. Download any of the lastest recoveries for Acer Iconia a500 (it will work believe me lol).
5. Put the recovery in the Image folder (Ex. Iconia/root-3.2.1/Image/) and rename it to recovery.img
6. Now open with Administrator Rights DotNetDetecter.exe
7. Continue, continue and continue.
8. If you have ADB Active just put it and it will install it. (If you don't have it just go to 8.1)
8.1 Shut down the tablet completly, connect your USB Cable *micro* (Tablet-Computer), take a paper clip and put it on reset without release it then press the power button and count until 4 or u4ntil you hear the sound when you plug something into Windows
8.2 Now your tablet is in APX Mode and the Acer Utility should now work.
9. Put your UID with a 0 in front of all the numbers (if you don't have it go to secret step).
10. Now let everything work. After everything is done you should have recovery now.
11. Press down volume and the tablet will take you to the recovery.
12. Download some ROM 3.2 or ICS 4.0.3, install it via recovery.
13. Download this file: http://www.mediafire.com/?9svnvdk982sxrw4
14. Install the version you have choosen via Recovery.
15. Voila! Your tablet is revived right now
Press thanks button if this helped you =D
SECRET STEP TO GET UID (IS NOT SECRET THOUGH... lol)
Just go to USB tools and use USBdeview, and is done... (Remember to stay in APX Mode)

Acer Recovery from the Market should have the most recent RA Recovery, and the original GPL compliant CWM recovery.
Or if you already have the original CWM, you can get the most recent RA Recovery here. Just check the threads for the flash files.

For CWM you will need to go to tegraowners.

Problems with opening up settings to turn on usb debugging
Hi Travisantonio,
I have a question:
Did you have any problems opening up the settings when you were on the black "android system" screen?
My touch screen is completely unresponsive at the moment.

Maybe I didnt read or understand everything but with my tab USB view didnt give me my ID or it wouldnt work. Got into ADX mode but couldnt get things working. Tried ADB to list devices and would never list anything. I heard my computer beep when I would hook it up but couldnt really do or complete anything. I couldnt get the DOTNETDETECTOR (PBJUPRADE_ to work. Tried A500 APX flash utitlity. Tired nvflash and falied. Guess I should list more information but at this point I tried so many things to recover dont remember the order I did things. I originally tried to upgrade to a Rom but all things failed and actually not sure what ever got completed. Only thing I could tell my tab did besides black screen was the power button either was white(some type of one) or orange.

This helped me to recover my bricked Acer 500 tablet after a failed ICS upgrade. The Acer update seemed to go okay, but on reboot it froze at the Acer logo and had an error in the corner. Every reboot or button/reset resulted in this. It would not recover or do anything else. I was able to get the USB device ID /serial number using the USB deview 64 program in the usb folder. There were several entries for the tablet but only one had a usable number (bottom right line at the end). Then the tool wiped the tablet and reloaded 3.2.1 and booted to factory new. Thanks for the instructions and to all the other XDA-ers for the tools. I am now on ICS properly.

Trying to recover a bricked acer a500, I just have a black screen on boot with no boot logo, vibration or letters or words on the screen
trying to enter recovery/update mode doesnt work
Im up to the step where is says put in your UID into the program
Just go to USB tools and use USBdeview, and is done...

I did this and found the device but where exactly is the UID located?
looking at other threads, the serial number is the UID however the serial number entry is blank for this device

how did u get yr tab like this???
if u have total black screen - is the power button lite on?????
what bootloader version are u on
have you had a custom recovery on there
to get your cpuid follow the first link to a guide in my signature - you need to follow steps in the guide if you have any probs then post in the guide thread

the previous owner said he tried to install a custom rom and I think it crashed and this is the result
the power light turns on (white)
if I just power it on, the backlight turns on however its just a black screen, nothing else happens
apx mode seems to be the only thing working right now, I thought this method would be my only chance to get the recovery mode working again
I dont know anything else about the tablet, bootloader ect...

ok thats cool, apx mode works!!!
well try this first - using hard reset:
1) Turn off your tablet,
2) Rotation lock on your left;
3) Press Vol Up closest to rotation lock and power on simultaneously
4) As soon as the tablet vibrates you can release the power button and you should start to switch rotation lock left and right till you see
Erasing Userdata...
Erasing Cache...
Vol Up is still pressed;
5) The tablet starts to format
6) Your tablet will be as clean as it can be.
otherwise plan B!!!
do u know whether tab was running HC or ICS?
u need some package files and a flash tool either apxflash or nvflash
if u start the tools and then connect your tab via usb cable to your pc
there are links to guides in my sig
my cpuid guide shows u what u need and where to get it, info about your cpuid too and drivers - altho you wont need to worry too much seeing as youre in apx
civatos guide has all the links to the packages and all the info you need to patch the bootloader, then you can flash one of the ics roms and youre all good!!!
the process is simple enough - but if you get it wrong it can be frustrating as heck!!!!

tried that method, get no vibration, devices just turns on to the black screen like normal
the only problem right now, I cant retrieve the uid
adb
when I type adb devices, nothing shows up
A500 manager
tried to the use the uid retriever tool however it just stays blank, same for the bootloader
it says it detects the A500 in apx mode
usbdevice view
shows no serial number for this device
I see there is a A500 motherboard on ebay (cant link to outside links...)
"Acer Iconia A500 Tablet Replacement Parts - MainBoard - 32GB MB, H6000 001 PBJ20"
"Complete with Android 4.x installed, 32GB memory and ready to install and boot."
could I get that and just replace the whole mobo and it will work fine?

OK just clarify - black screen, that is, nothing at all displayed AND Power Light ON??
IF u r in apx mode then
U have a couple of options
EUU flash back to HC 3.2.1 or
apxFlash to ICS
Everything you need for doing this is in my cpuid guide link in my sig.
open apxflash tool do not connect your tab Yet
Go as far as the enter apx mode
Now connect your tab to yr pc
Windows should install apx drivers
Once installed. try clicking blue arrow first
If u don't see the do u want to flash window then
You'll need to click on the "enter apx mode " button instead then
Click blue arrow
Hopefully the PC and tab are feeling pretty friendly and decide to take each other on
The tab should flash the bl and install recovery.....u should be good to go from there!!!
EDIT you can try cmd prompt on nvflash folder
Run a500.bat or.bat file that should kick you to bootloader mode
its really important that your screen display something in white letters!!
Entering Acer download mode OR
Entering apx mode
The flash will fail if u don't see something like this. This holds true for all methods

Wayyyy outta my league m8. Sum1 else will know....

yes, its just a black screen, no vibration, no boot logo, no letters or words on the screen, backlighting for the screen is on, and the power light is on
when I press the blue arrow in a500 apx flash tool it asks me for my SBK, going to that generator site it then asks for my UID which I cant retrieve

if you do not have your cpu id and
if you do not have access to adb and
you're stuck in apx mode
then things are looking grim.....
the only way to get into your tab without yr cpuid is fastboot
but you need adb working for that
someone else was stuck in apx mode a day or two ago, try a search...maybe...

I'm sorry guys I was a little off of this thread .
I will be glad to help you guys to get your UID or any problem that you have even though I don't have the Tablet anymore.
Thanks for all and God bless you all.

There is no way to fastboot the tablet in that mode, the only way is to get the UID and then decode it and NVFlash the Bootloader after it is done then put ICS or HC and the EC_ROM files and the tablet will be working again.

I'm gonna throw in the towel and just buy a new mobo for cheap, it seems im screwed without the UID and cant retrieve it either
I wish the previous owner would have gotten the UID beforehand
thanx for the all the help though

[Solved] Mystery bricked tablet. Black "android systems" screen

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????

What I've learned from this whole process is that all of the obstacles I'm facing are due to my lack of knowledge. Thanks for sticking with me Dibb. I can't thank you enough.

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!!!

Hi m8 Hwya goin - just got home - what's the lay of the land???
Holey motley we just had a good shake....thort was gonna carry on thank fk it stooped, phew, just been awhile since we had one like that, scary
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.

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...

Any chance to grabe cpuid after brick?

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.
