[PROBLEM SOLVED]
Ive been flashing back and forth to different builds trying which is better. I made sure I took the cautions not to flash builds that would brick my phone. There were 4 times that I soft bricked my phone but I was able to revive it. However, my little game has come to an end with this last one. The fault was this guide: http://forum.xda-developers.com/showthread.php?t=817186.
Little did I know, by doing a repartition and not loading anything to the NAND resulted in the bootloader not being installed. (Devices like this should have a ROM programmed to recover from these errors, think Gigabyte) Upon reset, the phone went out and didn't turn back on. ODIN reports success. Now the phone cannot turn back on, no matter what battery pull method I use, I get nothing on the screen. So much for fail-safe protocols Samsung has implemented, if there are even any. Poorly engineered!
EDIT:Thanks for all your suggestions guys. So yes this phone was definitely bricked beyond any software repair. I was going to JTAG it but I figured there MUST to be some hardware bootloader implemented. I went ahead and did the USB JIG and surprise, it booted from the hardware bootloader. I used ODIN to flash JFD and it works now. So my guess is samsung did implement a fail safe, which is the USB trick and forces the phone to boot from hardware. If that is true, this phone is brick proof, provided that all electronics still work.
EDIT 2: I am wrong about the bootloader being hardware. Some say it is flashable, so it is possible you can get a real TRUE brick and must need JTAG to revive it. Fortunately for me, I was able to use the USB JIG method to get it back up and running. Too bad, a new phone would've been nice.
Not poorly engineered, just poorly made user input.
Yes true, but samsung should have taken into account accidents like this will happen then they dont have control over who administers their update. People have bricked their phones by doing the factory update. When I design systems like these, I always make sure there is a fail safe backup that the user cannot modify. I am sure samsung has one and maybe they just dont let us access it.
I sometimes encounter the same error message but I never repartition. Luckily, i never clicked on it in Odin.
But you have to realize that most of those bricks are because people modified their phones from factory (ie. Voodoo and OCLF). Odin, a program used by internal Samsung engineers, was never meant for the public and shouldn't be used unless you know how to use it.
I agree, there should be an absolute fail safe if worse comes to worse, but the point I am making here is Samsung isn't wrong in this case.
When you violate warranties and experiment you tacitly accept responsibility for your actions. To not do so is not an act of rebellious ire...it is an act of denial.
Manufacturers do not, nor can not prepare for all scenarios because the possible number of scenario's to cover are legion. I don't see it as realistic especially for them to prepare for brick scenario's created by using a leaked internal engineering tool that the community has figured out largely through trial and error either. OTA and Mini Kies bricks they are responsible for, for obvious reasons, and Samsung and T-Mobile have taken responsibility for these scenarios because they are ones of their making.
XDA is not a place where people file warranty complaints (though some do complain). It is a place where people experiment, hack, and customize smartphones. Though some manufacturers do a better job than others at getting out of our way here (Samsung hasn't done so bad here relative to say Motorola), I don't think any of them particularly "care" about such community efforts in any meaningful sense. And why should they?
By modifying our devices aren't we quite clearly saying we're taking matters into our own hands? You have to balance your strong desire to tinker with the reality of where responsibilities lie.
These phones are some of the most difficult Android phones to brick. Anecdotally and statistically shown to be. Not impossible of course, but quite difficult. I feel for your bad experience but at least consider shouldering some of the blame.
Thank god i am too scared to use odin. The deepest i go is clockwork recovery, but good luck with your paperweight.
Too bad the SGS is so light, it wouldnt make a good paperweight, or even a brick.
but seriously, the warranty is there to protect users which this happens to, assuming it wasnt voided by hacking the phone. Are you asking samsung to take into account that you would hack the phone and provide a way back after you have a bad hack and probably make themselves liable by providing that way back in case it does not work properly?
I want to be clear that I am not blaming samsung for this but I thought samsung could have done a better job. Ill admit, this phone was the first phone that impressed me in years and as an engineer, I am hardly ever impressed; other engineers will get my point. I wish they had some soft of fail safe mechanism. For us who like to tweak things, I get we get what we deserve. But what about those who dont like to tweak and still brick their phones? i.e. those who use Kies Mini and still brick. I still have warranty on the phone and I'll try to take it up with Tmobile, hope they don know much about flashing. BTW, I tried using the other program but no go. All the drivers were installed, rebooted computer...nothing. I think it is because I have W7 64 and not 32?
Have you tried the jig method of getting into dl mode?

Keep on flashing, and eventually Odin will probably save your butt
Don't be scared of it, it works great. And it is safe to use.
========================================
I'm really sorry about your phone man, I didn't know that you had to NAND before re-partition, thank god I've never checked that but I might have in the future had you not shared this with us, so thanks a lot!
I guess your loss is everyone elses gain
No I havent tried the Jig method. The thread says that I need to have at least the samsung screen, so some kind of activity. This phone is just off, nothing comes on, no buttons, no screen...just dead. I think when I followed that guide, it told be to repartition and then reboot with the "PDA" field empty. So the phone rebooted when it finished formatting without installing anything. Now the NAND is at a "blank" state and I do not have any bootloader on there. Anyone know of a method to install a bootloader without the phone turning on?
I might be a little too far out of my element here but I think I found a guide to remove the sdcard and format it via pc one time when I was in a similar situation. I am at work currently and I also cannot remember if I have the link saved.
Maybe some phone expert in your city may help you to install the bootlaoder. I think it's called jtagging, I'm not sure though.

Just call Tmobile and tell then that you were upgrading to froyo 2.2 using Kies mini and it froze...
I had a black screen once. I was flashing in odin and knocked the cable loose. I think I had to remove the battery, open odin, plug the usb cable in, then install the battery and possibly hold a key down on the phone. I believe the download screen then came up. Otherwise the phone would not respond nor would any lights come on

Depending on which drivers you installed (and there seem to be quite a few floating around) you might need to disable Driver Signature Checking in 64bit Windows OS's if the drivers are not signed. The easiest way I've found to do this is with EasyBCD . Install it, run it, click Advanced Options and enable loading of unsigned drivers. Do this before loading a potentially unsigned driver and you're good to go.
Just a tip, and my lengthy diatribe on responsibility was more to stem the potential tide of trolling such a thread is likely to generate than dump on you. I know what it's like to brick things. I've been bricking stuff for 30 years lol.

To disable driver signing, you ONLY need to run a single command and then reboot. And this applies to both Windows 7 and Vista.
Also to the OP.
You say you have no bootloader, but can't find ANYWHERE in this thread that says you were attempting to flash a bootloader. In fact, you can **** up partitioning, and your bootloader is still in tact. Been there, done that.
Do this. Plug the phone in, and leave it charging for about 30 minutes. Pull the phone off, hold the volume buttons, and plug the phone into a computer. See what happens. I had a ****ty situation end up happening to me, that I couldn't get the phone on for about 30 minutes. I had already even called T-Mobile for a replacement.

This "hardware" bootloader as you are calling it, is the exact bootloader that you can flash and TRULY brick your device. It is NOT a failsafe in the way in which you are referring. Please, please don't call it this. There are plenty of users on this forum that are clueless. The jig method, is a hardware jump point that Samsung has built in to allow you to get to download mode situations where the button method does not work.
As I mentioned earlier, you didn't flash a bootloader. Nor did you full on brick your device. Glad your device is back to normal now though.
my apologies then, it would be easier if samsung gave us the schematics, but that would never happen. So when we use odin to flash, we are not flashing the bootloader as well? Is the bootloader located on another ROM that is not easily accessible? I guess ROM would be the incorrect term since you stated you can "flash" the bootloader.
[ABANDONED] My worries have been aliviated by the people posting here that T-Mobile did not check for an unlocked bootloader. That's enough for me to close the issue. If someone does need to find the answer to this question, feel free to pursue it otherwise I consider this [CLOSED]
-----edit above-----
I've already searched for this EXTENSIVELY and need more help. I have a similar problem to this thread (which wasn't resolved), but didn't want to revive a dead thread from Dec '10 to ask this.
First and most important question is: WILL I NEED TO DO THIS?> Will T-Mobile check for the unlocked bootloader on a broken-screen phone and will they notice my MIUI rom? (I'm REALLY worried about this because rooting my phone does void the warranty, but honestly I didn't break it. The screen just stopped working. Really worried = the search for a solution).
Is HTC warranty a better option? (I'm actually the second owner and the original owner is going to try to do the replacement)
I've realized that I can use Android Screencast to see what the phone is showing, and touch input still works on my phone (though Android Screencast isn't letting me use my computer mouse/keyboard to use my phone). This is only available on a rom/backup with USB debugging enabled, and shows CWM Recovery (using the latest version).
Can someone please help me go through all the steps needed to restore everything to stock? I am cursed by this issue and realize that someone would need to take over an hour to figure all this out.
>>I know I'm asking for a lot, but this is a great community to be involved in and I've searched all over for help before posting.<<
__________________
P.S. I've also looked at [Guide] Remove permanent root, and I need to know what extra steps I will need to know with a broken screen. CWM 3.0+ presents a problem for stock rom, and I need one with USB debugging enabled already.
Also, fyi I used the Rage/Gfree latest version available as of Jan 24 (when I rooted). I did not flash the Engineering HBoot, which would probably help.
What i found was they dont care about the software. confirmed twice. Apparently it is a known defect in the phone that the screen stops working, they will admit it now. We have done 2 warranty replacements and the first one at the time of the post, they tried to charge me for breaking the screen (we did a better business bur Complaint) and got refunded. The second time they didnt even question it and we werent even charged.
So no they dont care, dont worry about it.
I just so happen to have the exact problem as you, i stepped on my phone leavng the screen internally broken put the touch screen still worked. I was running CM7 and i called them and just sent it in with no problems. there not there to look at the software and are not going to take the time to replace screens on all the phones they get in first to see if there rooted or not. If you cant tell its rooted by looking at the screen (i mean it is broken) then theres no way they will. Just send it in and you'll get it in about weeks time
I had this problem and submitted it to warrenty, anyway. They asked me three questions, is the screen cracked. Is there any external damage, and any water damage. All were no's, so they replaced the phone without ever checking for root.
Thanks for all the responses. All three of you have reassured me to the point that I'm not going to worry about it either. While I appreciate that T-Mobile is not going to charge me for rooting my device (which I should be able to do), I am annoyed that as a secondary owner I do not get warranty support and need to have the original owner take care of it.

Stumbled upon this a bit ago, a company called Mobile Tech is offering an "unbricking" service on all versions of the Galaxy Tab. At the time of this writing they charge $50. I have not used this service, am not in any affiliated with this company and cannot vouch for their work, so beware. Just thought someone out there might use this when other options aren't available.
They have a nifty video up on youtube showing how they do it:
it will be a good help for those who brick their tab because they ain't follow the steps .. thanks for sharing this out
I can actually vouch third party for this service. Have had two friends use it and the device was returned within a few days. If I'm not mistaken, the guy lives in the southern US, but can arrange international he says.

This is cool, but I would recommend trying to go through Samsung first if you are still under warranty. I screwed up my primary bootloader and contacted them. They took care of shipping costs, fixed it up, and sent it back in about a week and a half. If Samsung hadn't fixed it I would defiantly have payed the $50 here though.
WOW, that seems like a lot of work for $50.
Thanks for the info, should I ever screw something up its nice to know there are people out there who can clean up my mess!

Hi spacemoose1
Thanks for link and as always, thanks for honeycomb port. I would like to ascertain the definition of BRICK? with your help, if I may.
(disclaimer: pls forgive my wrong terms or exagerated explanation, but most importantly, pls correct me if I'm wrong)
BRICKed = software total lost, must use JTAG to force revive it, Samsung has it, or buy from web supplier around 300 USD ??? 500 USD ???
JTAG is a device to push software into all newly borned IC. I.E. when factory make IC, it's empty software inside, hence has a special device to push voltage into all sections of the IC, then force the code in.
Another term is ???CRASH??? or ???HANG???, (I don't know) anyway is not BRICKed, hence a reflash can recover it.
Samsung uses proprietary method a lot, not follow conventional, make usb driver very complex. USB driver install EXE around 15MB to 28MB depends on version, ALL work the same.
but, when the device = sgt7 in different state/condition, the driver must RE-ESTABLISH again, or else cannot work.
I.E.
state 1 = "OPERATIONAL"device in android operation, normal use, surf web, phone call etc
state 2 = "SLEEP" device powered off, show battery big icon charging when powered by charger
state 3 = RECOVERY mode
state 4 = DOWNLOAD mode - this is one of the way to FORCE flash to recover, as long as bootloader and something still intact
state 5 = PHONE-!-PC mode
stage 6 = "COMA" device powered off, NO show of battery big icon, even when charger supplied. Don't panic, let it charge fully 4 hours from 2 amperes supply, 10 hours from PC 500mA. It will start again !!!. Battery big icon will appear around 30% battery charged, I know because that's what I saw. I didn't check when it's in 10% or 20%. The 1st time I check was already 30% up from no-boot or no respone.
User need to plug device into PC during each of the state above at least once, in order for various flashing functions to work.
i.e. when it's a newly arrived device, usually install the usb driver 1st, with device state in android OS running properly, then plug in to USB and see "new device detected" installing, pls wait. Finished.
But when flashing via Odin using state 4 = DOWNLOAD mode, user may experience no connection, no COM3 or something. Because device must be unplugged in USB, power-up in state 4 = DOWNLOAD mode, plug in USB, "new device detected" installing = RE-ESTABLISH, done. UNPLUG USB, replug in usb, then COM3 appears FLASH will be succesfull.
same goes for other state.
p.s. many users reported BRICKed but then recovered WITHOUT JTAG is misleading beginners, hence should rename the term to ???CRASH??? or ???HANG???. although some previously use "SEMI-brick", which is acceptable.
stage 3 = ClockWorkMod flashing (super convenient, especially on the move without PC)
stage 4 = Odin / Heimdall both works (still convenient and easy )
stage 5 = Odin / Heimdall both works (still convenient and easy )
???CRASH??? or ???HANG??? or "SEMI-brick" is usually SUCCESFULLY recovered via restock+PIT
(final disclaimer, incase above is correct and help and is copied, pls correct whatever mistakes found, feel free.)

Yeah, warranty repair is always a better choice. But sometimes you've already voided the warranty, lol.
I guess, if u change factory installed rom/kernel warranty gonna be history
thanx for the post ... it might gonna be the last resort...

I pretty much agree, but I might refine:
BRICK= Unit does not power up, visibly charge, reach a boot-screen of any kind including a service or "download" screen. A device in this state requires service from the manufacturer or an individual equipped with the proper tools. There is no other way to recover a device in this state.
SOFT-BRICK= Unit powers up, reaches a "download" or service screen, visibly charges but does not boot into an OS. Crashing, hanging etc. all apply here. It is easy to recover a device from this state so long as one has access to a firmware that was designed for the device and the ability to flash said firmware.
SEMI-BRICK= See soft-brick above
JTAG= Provides access to system hardware by applying the correct voltage to the correct pins in order to push software via an external program.
In regards to the usb drivers, there are only actually 4 states
1. Active userspace
2. Serial gadget mode
3. Recovery
4. USB storage mode
And there is a separate driver for each of these (except recovery) in the Samsung driver package that should install automatically when the device is plugged in during normal use on a stock rom, or with the installation package available on the web.
The rest of it you've got pretty much correct.
Money seems right, but the amount of work that guy has to go thru is amazing, so much to tare it apart, and reassemble. Then again when it is put back toether, he checks it, what if it did not take the fix... all over again.
Hardbricked Tab Save by Mobile Tech
I hardbricked my galaxy tab bought in Cambodia. My little brother open the tab trying to take the battery off and put it back on, thus void the warranty, found him on the Samsung vibrant forum, sent the tab to him got it back good as new. This person is professional, honest and good communication with his customers, you'll be happy with his work, if he can't fix it you get your money back (minus shipping and diagnosis)...Glad he is arround to help...

You should post this in Q/A thread on its own as its very helpful and maybe it will stop the 1% of people saying help my phone is bricked comments ... the other 99% don't read anyway otherwise they would discover their phone isn't bricked and if they read properly it would not have gotten to the state in the first place .. and no I never posted something like that myself >:¬}
but well done on this..

Nice find. For that amount of effort disassembling, and reviving, $50 is a very realistic price. I'll keep these guys in mind if I run into issues with my tab.
$50 for that much work is an absolute bargain! I wish I didn't live in a country where you get charged $200/hr for someone to pick their nose.
It's actually not that much more difficult than popping an OS install CD into a hosed computer and pressing 3 keys to let it run through the installation after flashing a corrupt motherboard BIOS. Yes, it takes familiarity with the software and hardware, but it's by no means a feat that requires a special skillset.
Granted, few people have JTAG stuff handy, so $50 is definitely worth it if you've hosed your device, but don't make it sound like he's sweating and coding the bootloader by hand, strenuously manipulating micro tools to disassemble the tablet and flipping DIP switches to restore the bootloader. You spend 5 minutes taking apart the tablet, you attach the JTAG cable, run the supplied software on your computer, and sit there recording the screen with your video recorder while the progressbar moves from 0 to 100.
Again, it's worth $50 simply because not everyone and their mother has JTAG hardware sitting around, but by no means is it hard. It's the same reason I can get away with charging $100 to clean viruses off of a computer. People either don't have the tools or don't know how to use them. That being said, I don't know a damn thing about using JTAG to restore a corrupt bootloader, nor do I have the right hardware, so I'd pay $50 if I were ever in the situation.
Edit: And yes, $100 for a virus clean is a lot, but people generally change their mind when I explain to them why they got viruses, as well as installing proper antivirus software and then instructing them on how to avoid infection in the future. I rarely get repeat business from the same customer but I get A LOT of referrals ;p They're happy paying that much when the person educates them instead of cleaning, not installing/explaining, then having to bring the computer in again two weeks later for another wallet-gouge, which most other computer 'repair people' gladly do over and over.
Everything in this world is rinse and repeat... The money comes from time spent learning to use the hardware properly, micro soldering skills (which isn't easy, no matter who you are), confidence enough to offer it as a service, not to mention the couple hundred bucks for the jtag software and hardware.
Now, the fact that if you have your device in a bricked state you likely voided the warranty, it's a 600 dollar brick if your samsung tech recognized it... 50 bucks is a steal to not deal with samsung anyway.
Try to be less pompous next time oh savoir of the hundred bone virus... Your poop stinks too, promise.

It's actually not that much more difficult than popping an OS install CD into a hosed computer and pressing 3 keys to let it run through the installation after flashing a corrupt motherboard BIOS. Yes, it takes familiarity with the software and hardware, but it's by no means a feat that requires a special skillset.
Granted, few people have JTAG stuff handy, so $50 is definitely worth it if you've hosed your device, but don't make it sound like he's sweating and coding the bootloader by hand, strenuously manipulating micro tools to disassemble the tablet and flipping DIP switches to restore the bootloader. You spend 5 minutes taking apart the tablet, you attach the JTAG cable, run the supplied software on your computer, and sit there recording the screen with your video recorder while the progressbar moves from 0 to 100.
Again, it's worth $50 simply because not everyone and their mother has JTAG hardware sitting around, but by no means is it hard. It's the same reason I can get away with charging $100 to clean viruses off of a computer. People either don't have the tools or don't know how to use them. That being said, I don't know a damn thing about using JTAG to restore a corrupt bootloader, nor do I have the right hardware, so I'd pay $50 if I were ever in the situation.
Edit: And yes, $100 for a virus clean is a lot, but people generally change their mind when I explain to them why they got viruses, as well as installing proper antivirus software and then instructing them on how to avoid infection in the future. I rarely get repeat business from the same customer but I get A LOT of referrals ;p They're happy paying that much when the person educates them instead of cleaning, not installing/explaining, then having to bring the computer in again two weeks later for another wallet-gouge, which most other computer 'repair people' gladly do over and over.

I've got to call you out on this one. Mis-connecting or shorting any wires will lead to a damaged PCB and an un-resurrectable TAB. I'm also a Systems Admin for a living so I understand where you are coming from. You must realize that I solder at levels of .1mm in spacing on the Captivate, Vibrant and Nexus S. Electrical engineers and technicians have first hand talked with me about the difficulty of doing this and is NOT something that anyone can do. You'd think twice when you burn up a phone or two valued at $500 a pop trying to JTAG them. There is more skill involved than you would think. Not to mention the liability when dis-assembling the device. JTAG software is decent but it's not fully automated. There are TCK frequencies, RTCK frequencies different PBL partition sizes, full dcc loader read/writes and the requirement of EXACT voltage from an external power supply that are needed in MANY cases. Plus, there is little to no support when fixing a device. This means that if you can't figure it out, nobody else is going to for you. I'm not trying to brag but yet point out that this isn't like plugging in your phone for an ODIN flash. I've taken hundreds of hours of time and 1000's of dollars to create what I feel is the most trusted JTAG authority online ANYWHERE. I greatly appreciate having the opportunity to help the community and enthusiasts in this community. If this was as easy as you are claiming, you could get JTAG hardware and a manual at Best Buy. I have to say you put it best when you said you don't know anything about JTAG... Ok end of rant I was just a bit bothered by your post.
Ok with that being said, thanks for the personal testimonies and compliments. I will be here whenever anyone needs JTAG assistance in the future or around the forums to help answer Q&A when it doesn't require JTAG. Here is a Nexus S promo to realize how tiny some of these things are

Hello to all good guys in xda-developers forum.
This is my very first post and I really feel desperate and need your kind help.
New Acer iconia with stock firmware 3.2.1 was nicely running this morning until I tried to root the device.It was supposed to be very simple process and not to get into dirty complicated procedures but the gingerbreak.apk did not work as expected so I tried alternative methods.What I read in various forums was that the gingerbreak application is not able to root the new firmwares version so I tried to downgrade the firmware to 3.0.1.
Downloaded the Acer stock recovery firmware EUUs_SBK_Acer_A501_0.017.01_PA_ATT.exe and attempted to flash onto my tablet .I think I did all necessary pre-installation checks.The process started but it stopped on 10 percent for about 30 minutes without any progress.Only Acer logo was displayed and 'entering file downloading mode' at the top of the screen.
After long time no change I finally gave up and unplugged the device from the USB port and restarted but nothing works since then.
1. No vibration on Start
2. Black screen
3. No new USB device appear on my PC
4. No sign of any activity other then power button light
I guess the original firmware was wiped but the new firmware was not flashed...for whatever reason...perhaps the worst scenario.
I will really appreciate If anybody may give me advice how to fix it.
So it turns on but does not display anything? Have you tried to hold the power button and volume down button at the same to when you turn it on to try to get it into recovery. Also there is a little reset button on the side you can try to push.

Acer or the store did not brick it
i THINK If you mess with the rom on your tablet and... BRICK your device .. you should tough it out and fix yourself... Acer or the store is not responsible for this .But then you could also argue that if they had not locked the bootloader this type of bricking would not happen..
So i say go above and beyond to try to fix it from the help on here.. if that fails.. THEN Maybe exchange it.. Its wrong to brake something then expect someone else to foot the bill. Yes im to honest for my own good at times... Acer has also been known to repair .
If you bought a extra warranty all of the above in my book is out the window.. Make them replace it ..
GIGGLES..
Good luck on getting it repaired ..and be more careful next time..
Piece of cake to fix if you kept you USB serial number (from the downgrade tool)???
===== If you have your USB serial number ====================
1. Lets assume you know your USB serial number. If not, then you might be able to get it from your registry.
2. Download my flashing tool at http://forum.xda-developers.com/showpost.php?p=20680452&postcount=137
a. Open up the readme.pdf for the instructions on how to flash
3. KEEP your acer unplugged and run the program
4. The program will install the APX flash drivers and will tell you to plug in the USB. Ignore this step. It will not work. In the instructions skip steps 3, 8, 9, 10.
5. Eventually the flashing tool will timeout because you do NOT have the tablet connected. It will then display a message box telling you how to use a paperclip and the power button to get you into APX mode. THIS IS THE secret to getting the tool to flash your ACER. However, once you get it into APX mode you will need your USB serial number (without it, you are fubar).
a. Plug in the tablet to your computer with the USB and paperclip yourself to fastboot.
6. Now in step 11, enter your USB serial number
7. Now just follow the rest of the instructions.
====== NO USB Serial number ==========
If you do not have your USB serial number than you are going to be out of luck, unless you have ever connected the device to your computer. If you did, then your registry will have a history containing your serial number.
Google usbdeview tool and download it. This will show the serial number of any USB device you've connected to your computer.
===== No Serial number, never connected it, what to do ==========
If you have no serial number and cannot get it, then hopefully you can get to recovery mode (power & volume) and flash using a signed update.zip from ACER. Download one of the update.zip's and put it on your external SDCard and then boot to recovery.
=== Bricked and No serial number, never connected, and you fubar'ed the recovery image ===
If you never connected your table to the USB and your computer to get the USB serial number then you are NOT going to be able to flash it to fix it.
If you fubar'ed the recovery image then you won't be able to get into recovery to run the ACER update zip.
At this point, you can still get your tablet into APX fastboot mode using a paperclip and the power button. But I know of NO way to flash it without the USB serial number and I know noway to get the USB serial number from the APX driver. I've tried and looked at getting the serial number from just APX mode, but I cannot determine how to get it. Someone out there might know.
Hope this helps,
TD
Your CPUID can also be found in the uid.txt file in your cwm backup folder - /mnt/external_sd/clockworkmod/backup/ - just remember to drop the 0x when you need to enter it

Honestly if more people returned bricked phones/tablets etc... they would quit locking them down... the you broke it you fix it because they want to keep people from doing things they should be able to do with THEIR system they bought... In other words I completely don't agree with this at all.. If everything was unlocked and such then I would support the you fix it, but then again we wouldn't be running into these issues now would we. But then again Most people need people to babysit them and tell them what they can and can't do with what they own..

@wade7919. You clearly have never worked in IT support on a hardware level.
Or maybe, I am barking up the wrong panty-leg?
If you bought a high dollar corvette, GM will support it. If you add an aftermarket chip, and your engine blows, do you expect GM to fix it? No. I wouldn't expect it either. Not their problem. Just because you can add a chip, doesn't mean you should do it.
That's why they try to lock bootloaders. To prevent users from doing things they shouldn't. Unlock them, and it opens a whole world of issues based on "open source". God help us if they unlock bootloaders.....
Not sure what you are getting at. I am under the belief, if you broke it, you fix it. Take responsibility for one's own actions. Shouldn't take the panzy pussyass way (no offence Erica and werecaltf), and return it for replacement. Suck it up, and learn from experience. Otherwise, the next device, you'll do the same stupid thing again.
I like things the way they are. Difficult, but not impossible. That separates the people with balls (again Erica and wercatlf, no offense), from the sheep.
But if you fubar the device, own up to it, and fix it. Don't pawn it off to somebody else (return it). And if you don't have the brain cells to have a backup plan before you start... Well, don't shed tears over it. Own up, throw the testosterone in the garbage disposal, and fix it.
Somebody give me a zanex...
And people, stop using Gingerbreak!!!!!!
Why locking a bootloader will cost ACER billions
Moscow and wade7919, you both make good arguments.
But it is what point of view you're coming form. If I bought a car and changed the RIM's on all 4 wheels and the engine blew up, would GM refuse to honor the warranty?
However, if I put jet fuel and alcohol in for gasoline and blew the engine why would they honor the warranty?
So, the question here is does rooting a device cause actual damage to the device thereby preventing rooting saves them warranty issues? Or is the device also considered to include the software and is covered under warranty?
I'm not taking sides here, but you both are making very good points but with different examples at different points of view.
So, lets look at other items and see if we can draw a parallel. If I buy a brand new Dell computer and send it in for Warranty and there is nothing wrong with the hardware they charge me (correct?). So if I fubar the OS or load something that caused the damage I pay for it or fix it. If there is actually a hardware failure then they cover it under warranty.
So, why does an Android MFG take the warranty one step further and include the OS and take steps to lock it so you cannot change it? Well, this is because nobody owns the OS (it's open source) therefore they take ownership of the build. Because there's no Microsoft to blame, they lock the software and consider it to be part of the overall device (Apple claimed this in their lawsuit). So, in the MFG's mind, there is no difference from the screen, keyboard, or the firmware & software.
So the question is what do you think should be covered under warranty? Most people think it should be just the hardware like a PC. Others see the whole device which includes the OS.
My point of view:
What follows is my rant and my opinion (you are warned )
In my opinion, I had NO problem until they decided to lock the bootloader. I have no problem with them claiming warranty from A-Z and if I change anything they won't warranty it. No problem, I understand that and accept full responsibility. But by ACER locking the bootloader they went too far.
To me this would be like GM welding the hood shut on my car. Better yet, it would be like me waking up one morning and opening my garage to get in my car and discover that during the night GM welded the hood shut. This, in my opinion, is illegal. Matter of fact, in my opinion, it violates US Federal hacking laws because they enter a system and destroyed data. I eventually think OEM's will get a class action suit filed on them for this.
Secondly, Windows 8 is going to be the game changer. OEM's can now make a hardware device and sit behind only warranting the hardware. You have a problem with the OS, call MS. Also, there is a HUGE (I mean HUGE). Did I mention HUGE, demand for tablets in business. Businesses will NOT put a device that has all these consumer games and social networking loaded into the workforce. There are billions in business applications that can be made, but you cannot sell them if they only run on a tablet that cannot have games removed etc.
Example might help: Medical field <- Think of all the applications a tablet can be used to save costs in hospitals. Do your really want your doctor or nurse etc using this tablet on facebook? Insurance company's, law firms, retailers, traveling sales, etc etc (Government). The list goes on.
Developers will see this huge opportunity and will write applications because they can sell them to A-Z and the business buying them will buy them because they can remove facebook and gmail from their company owned tablets. Now, as more and more developers move to Windows they'll drop Android. Want another example, read about Netflix and the issues they have had supporting a fragmented Android OS. So, business applications will move to Windows, but you might say so what, the consumer market is still there. True, but all you need is one killer application that everyone will want and for that to only be on Windows 8. Want some examples, here's my list, NFL (or sports), Netflix, Skype (gee owned by MS now isn't it?), or something new.
Bottom-line is this, if ACER and the others want to lock their bootloaders then they have just taken themselves out of the game for any business sales. Can you imagine walking into a boardroom showing the Government how your new VA application will save the VA Hospitals millions next year alone and improve veterans healthcare. Your application runs on any HC Android tablet. Everything is smoking, going great, as you hand your tablets, ACER a500', around the room. They are loving it. You just hit 'pay-dirt', then someone says hey I see these ACER's have gmail, facebook, blah blah. We cannot have government employees using tablets with those applications loaded, your installer removes them doesn't it? Silence enters the room, all eyes are focused on you. Your mind see millions escaping which were just within your grasp, you pause, you think, and you say YES General as you grab your Motorola Xoom and say 'that's why we recommend you buy nothing but Motorola.'. ACER just kissed millions in sales goodbye (oh and this is a true story).
i do believe acer should lock the bootloader on there devices.
However thee are things I would be doing with my tab if it were not locked.
Acer should give us the ability to flash the bootloader and not use the proprietary software. Lock that software to there bootloader.for there protections.
Give us a wway to unlock it..AT OUR OWN RISK..
So it should be locked but have a way to unlock it with the end user understanding they are totally on there own ..
I would be OK with voiding my warranty.
@Dean,
"So if I fubar the OS or load something that caused the damage I pay for it or fix it. If there is actually a hardware failure then they cover it under warranty."
Yes, that is true. Bootloaders are locked, to prevent completely stupid idiots, from doing things they absolutely no idea what the sam hell they are doing.
The issue is, should we be able to return a device, after we fubarred it? Against warranty? To say, Hey, your weakness allowed me to do it.
Just because the ability to do it exists, and we can quote a thousand instances, It doesn't mean we should, and to shirk responsibility. And pass it off to the main individual.
The fact is, the policies and regulations are there, and we should abide. And if we don't, we have to own up and deal with it.
And if we don't, then we are no better than the low life of the world. The scum.

Very well put.I do know of a few people who have sent there device to acer after messing it up installing rom and telling acer.acer still fixed it free.
Honesty is always best
The evils of rooting
I'm still missing something here, why locking a bootloader does anything. Go get a Mortorola Xoom (not the FE) and you run the unlock OEM. It tells you that you are unlocking it. It tells you that you unlock it at your own risk. You cannot relock it until it is 100% back to stock. It asks you three times are you sure.
Locking the bootloader and treating everyone as an idiot is the problem. Just do what Motorola does, and stop being everybody's keeper. If they want to 'Police' this then you should have to call ACER and they fax you a form. You give DNA to prove who you are and fax it back. Then you go to a mandatory rooting class, that lasts for 5 days, where ACER preaches to you the sins of rooting. Then you have to take and pass a test. Then and only then, after passing the test you get a certificate. Then you call back, give them your certificate ID. Now they give you the secret key to unlock only your tablet.
That's the ticket,
TD
Bottom-line, it's not that they locked the boatloader, it's that you cannot unlock it. Like I said, go out to your driveway some morning and find that GM welded the hood to your car shut because they think you are stupid and shouldn't be opening the hood. Mind you that YESTERDAY, and at the time your bought it, it was not welded shut. That ladies and gentlemen is what ACER did with their OTA.

Okay comparing A Tablet or PHone to a car is stupid... Compare it to a Desktop Computer or Laptop... Companies do not lock them down so you can not use different OS's now do they.. They offer Backups to restore the system back to how it was with recovery partitions dont they? or they offer the choice to buy whatever OS you want to install correct? they don't limit you to say just Windows or *NIX do they? But we don't see laptops or desktops locked down to where you can't upgrade your system yourself or anything else... and any dumdass can do that without an issue most of the time. and there is more issues with viruses and crap on computers than phones or tablets...
So before you start making statements like compare this to that learn what to compare to first. If you mess something up on a hardware level sure pay for it.. if you mess something up on a software level because they decided to Babysit people its their fault. and if you think its the persons fault because they decided to open up a PRODUCT that they bought and own then you are one of the people that need babysitting and like everyone telling you what to do and how to do it. Go to an apple product then.

I still like my car comparison
I make the car comparison to illustrate a point, because when I compare tablets to a PC everyone piles on *****ing about MS.
Bottom-line it doesn't matter if it's a blender or a PC. I own it, you own yours and I can do what I want with mine as you can with yours. Now, again I have a BIG(did i mention BIG issue with them changing it on me after I bought it.
To get back on topic, is the original poster still out there?? Has any of this helped? Are you still bricked?? Give us an update so we know if anything worked or you still need help.
The device was returned and accepted for replacement by the shop.Got new one and feel very nervous to start rooting procedure over.I was really lucky that they did not charge me anything but I really want to know what I did wrong so I don't brick my new device again.
I will provide further details soon about my computer OS and firewall settings and perhaps we may figure out what I did wrong.
To all good guys who send me them suggestions and solutions I wanna say big THANK YOU !!!
Your help is really priceless and thrilled me deeply. Will update topic soon
Happy New Yer to all Android fans!!!
So...Back on the subject.
My device was purchased in Japan and its current firmware version is
Acer_A500_7.009.03_AAP_CUS6JP
Q1. Can I flash US or World Wide firmware version on that device.
Q2. Does anybody know the Acer's ftp download server address for Japan
Q3. I think its a good idea to dump my original stock firmware but it seems there is no way doing that prior rooting.So..kinda stuck .any suggestions appreciated.
P.S. I'm thinking about flashing the latest Rooted rom 3.2.1 V3 by timmiDean (thanks for your hard work) I read the instructions very carefully and I think that everything will go smoothly but just in case (considering the specific Japanese firmware version)
would appreciate any further directions by the author.
Thanks
Anyone owning a Fire 7 needs to stop drop and roll...literally. Please go to your tablet and with a file explorer (i don't know if you need root) in the root directory please try in whatever way possible to read the contants of all files (theres like 3 or 4) with 'fstab' in the file title. Look for ANY properties ANYWHERE that have to do with 'acm'. I am fairly certain, without root you can persist this property in ADB. Get your tablet, plug into PC and open ADB window and type:
Code:
adb shell setprop persist.sys.usb.config mtp,adb,acm
Your PC will light up like a christmas tree with new drivers for the tablet. If it does, then the chances are VERY high that you will be able to root and unlock your fire 7.

Can you explain what is the acm mode, its bootrom download mode? I do not understand what we can do with the tablet in ACM mode. If we do not get the tablet to enter the BootROM Download Mode this mode will not help us at all.
How does the computer detect the tablet when it is in ACM? I tried it on my Fire 7 and it does not install any driver ...
EDIT: I read this:
Code:
Before Download mode can be entered, the Preloader has to find out if a host is connected via USB or UART and running the MTK SP Flash Tool. It does this by configuring a virtual CDC ACM discipline on USB, so both lines are in fact serial ports and behave similarly.
The USB port will assume that the tool is connected if it receives a “set line coding” (configures baudrate etc.) CDC message. It then sends the string READY to the tool and waits for the reception of a token of eight bytes.
After successful detection, the tool can send the special Start command sequence (0xa0 0x0a 0x50 0x05) to enter a special mode that is only available via USB. It interprets the following commands (I left the ones marked with “legacy” out):

Anyone owning a Fire 7 needs to stop drop and roll...literally. Please go to your tablet and with a file explorer (i don't know if you need root) in the root directory please try in whatever way possible to read the contants of all files (theres like 3 or 4) with 'fstab' in the file title. Look for ANY properties ANYWHERE that have to do with 'acm'. I am fairly certain, without root you can persist this property in ADB. Get your tablet, plug into PC and open ADB window and type:
Can you explain what is the acm mode, its bootrom download mode? I do not understand what we can do with the tablet in ACM mode. If we do not get the tablet to enter the BootROM Download Mode this mode will not help us at all.
How does the computer detect the tablet when it is in ACM? I tried it on my Fire 7 and it does not install any driver ...
EDIT: I read this:

ACM allows a device to emulate ports. Example: the tech doesn't have a usb port to connect the tablet. ACM can be used so the tablet emulates a different port other than USB. In our case, ACM appears to be the God mode.

Had this device before. Got a new phone and gave it to my brother. But can you explain a bit, just entering those acm commands wont give you root, I know but what after that?
Will check this method when I go to my brother's.

ACM is a proprietary function mediatek uses to emulate the USB port as a different port so they can access their devices using various hosts. It's also a way for them to access the device without modifying the firmware or system. It's a clean, legit way an oem should access a device. This explains a lot of my discovery that kicked off this whole process. We could see all this happening in the HD 10 binary files, but we couldn't see how this access was happening or where it was coming from. My theory was Amazon used a back door and a mode or user ID greater than super to access devices without the use of private keys. Of course that was crazy talk and impossible and I can't blame any one of you for not believing me. I however never imagined this going beyond Amazon. I'm honestly in total disbelief that any of this is happening and even more so that my crazy cat lady theory was right from day one. I'm just greatful and honored that the few of you who didn't think I was crazy, took it to the next level. If it weren't for all of you, my theory would have been buried and forgotten. In the 3 years since I started all this I never imagined it would come to this. All of you are amazing!!!

ACM isn't a proprietary function from mediatek. TtyACM is typically used for modem-devices, but in the end it's just a serial-connection.
And the ACM you are enabling using this command has nothing to do with the ACM of the BOOT-ROM.
Also this has nothing to do with amazon or backdoor-keys or any super user access.
It is an exploit of the mediatek boot-rom which is part of the SOC and cannot be changed.
They are totally different things.

Does that mean the 2015 Fire 7 in (5th gen) may be able to be rooted? If so, do we have to do the thing where the back of the tablet needs to be opened and the pins have to be grounded?

If device is running FireOS 5.3.1 or lower it can be rooted via software hack. Otherwise, you'll need to crack open the case and play the pin shunt game.

Don't have to open the case! Need to start by bricking with 5.0.1 sideload, then you can talk to 5.0.1 preloader as in here:
https://forum.xda-developers.com/amazon-fire/development/downgrade-fire-7-2015-softbrick-t3894671
It'll be bricked with 5.0.1, but preloader with get into Bootrom via a button push, and that's all you need.

Yes it already does. A bit limited by the current low knowledge of the hardware but it will improve with time
and some software tool to help less skilled people avoid to have to do with a soldering iron and/or disarm the tablet.

Well that's an interesting approach and one I would not advise to the faint of heart. That said, it's probably the path I'd pursue on a personal device that I would be willing to sacrifice. Advantages of 5.0.1 bootloader outweigh other considerations in my world where simplicity, stability and minimal maintenance outweigh redirected blood flow.

Why not advice? Definitely safer than opening it up and poking around with a paperclip
But sure, if you have a rootable OS and that's all you desire both methods aren't for you.
That said the tablet is now basically unbrickable

It can need a paper clip and opening the device as well.
"With older preloader-versions you can then simply hold the left volume-button while pluging the device in.
If you have a newer version, you will have to open the device and remove the metal-shielding (it is clipped on)"

Most of my varied devices are bootloader unlocked which affords full control over hardware and flexible recovery from all but the most aggregious flubups. Not my first stroll through the turnip patch. That slobber lined path is far removed from experiences of the common user. Intentionally bricking a working device is not guidance I would give lightly during the early stages of exploit exploration. Same goes for blindly probing around the circuit board with metal objects. Die hards will eagerly take the plunge regardless of risk and share their experiences, good and bad, with the community. Tip of the hat to those bold adventures. Only after the liabilities and rewards are fully understood would I reconsider guidance for non card carring members of the geeks-r-us society. Seen plenty of noobs go down in flames naively following supposedly 'easy' instructions to nirvanaville.
Simply put .... a suggestion for the novel user poking around in the hardware is enough as a sign of being helpful.
Why should we insist trying to make them stay away from the world of electronics ?
I just suggest to start using a resistor about 1kohm when shorting test points or pads on the motherboards working from 3V to 5V.
This gives them a minimum margin of safety and potentially avoid or makes it less probable they burn some components on the PCB.
Later on they can try to lower that resistor value to a value from 100ohm to 200ohm if they didn't had the expected results and retry.
Many will burn some of their stuff, yeah ... why not, they are used to it. They paid for it and deserve to do what they want with it.
My view though, everybody has the right to express different point of view.

Agree with all the above including the sensible cautions. If one understands the basic function of an electrical resistor and the units involved then there is probably both interest and knowledge to proceed. Now we've addressed the 5% club I submit the rest should stay on the sideline until more is known. Same for the brink-n-revive suggestion that started this exchange. I hold no power over what individuals do with their devices. I can only provide guidance based years of experience that extends well beyond hand held gizmos.

I agree with both of you, all I'm saying is for those who have made up their mind and want to do this, I think bricking intentionally and then using the exploit is the safer route, since it's a software-only solution.
With poking around on the mainboard there is more things that could go wrong, I've seen people shorting VBAT to ground.
