I just bought g tablet. I need some help on where to start.
I read below to use Z4 root:
http://www.androidpolice.com/2010/12/08/how-to-unleash-the-power-of-the-viewsonic-g-tablet-and-turn-it-into-the-best-performing-tablet-on-the-market/
Also read here that I have to set up ADB first then root with SuperOneClick
http://forum.xda-developers.com/showthread.php?t=827209
Is it necessary to set up ADB? Can I just use Z4 root?
Android police say next step would be installing ROM like
Cyanogen 6.1, TnT Lite or ZenPad. Which one can be recommended?
I'm not sure what all this means I just want to follow some instructions to get this tablet working better.
Is there a way to back up before I try this so I can go back?
Sorry for all the questions but this is very new to me.
Thanks for any help.
I cannot figure out how to do anything
Start with the FAQ area, in my signature. It has information / links on the alternate ROM's available. They are rooted already and can be installed using the device's own firmware update process.

A little comfort knowing I'm not alone but I want to get it working. I need a tablet this size with flash so I can watch my movie at work
I was the same way with roebeet and a few others u will be savy in no time.
Make sure u get clockeorkmod 1st installed.
Partition ur sdcard and back up frequently. You can't break this thing with those things in hand I promise.
Purchase root explore and titanium backup for the rest.

I assume I need to do root first, right?
Is there instruction somewhere for installing clockworkmod?
How do I partition the sdcard for this operation?
Thanks!
that video helped me greatly,now after doing this is there no return to the manufactures OS? And it is recommended to clear the cache and how is that done?
clockwork instruction is here

Yes you can reflash back to the original OS, like if you needed to return it or something. Once you experience something different I promise you wont want to go back

It is not a requirement to partition your card. I have not (at least not yet- unless forced to with a future rom) and have had the G for over a month now and went through all TnT versions.
Currently using TnT 2.20
The problem with the guide linked above (-http://forum.xda-developers.com/showthread.php?t=865245) is that I get stuck at step one. I simply cannot for whatever reason flash Clockwork Mod 0.8
It just gives me the giant EXCLAMATION MARK /!\ and doesn't do anything. I'm following the directions perfectly.
So is this an issue with hardware revisions or something? Because as far as I'm concerned this tablet is busted if the exact thing that works for all of you doesn't work for me.
EDIT: Finally found a different SD Card and it worked. Don't know why. The card that didn't work was a stock 1GB Sandisk, card that worked was a stock 512MB Sandisk. Weird.
You can install Clockwork and flash ROMs without rooting your tablet first. You also do NOT need an additional SDCARD in your device; I did ROMs several times before adding an SDCARD.
Your best bet is most likely TnT Lite, although VEGAn is fast becoming the best ROM available and it's still in beta.

If root is not needed to flash CW or roms why even bother rooting it?

The roms root for you, so no manual root process. Putting CW on has a bunch of advantages.
Clear cache, data and Dalvik cache
Back up entire current rom and restore with it if problems
Fix permissions
Boot into usb storage mode and access internal space, even if device will not boot up.
Break out of boot loops
No complete need for recovery folder
That is some of the main reasons it is prudent to install it. Life line

Having root on the device is akin to having superuser/administrator rights on your home computer. It is necessary to have for the system administrative type applications you may want to use (e.g., TitaniumBackup) to help backup and restore your data / applications.
ok at first i was just like you guys did not know how to flash any ROM, or how the tablet actually did it or the necessary files needed at the required location, first off when you first connect the tablet to your pc gotta choose turn "turn on usb storage" on tablet, than go to "my computer"(where you see all your hard-drives) and open the new storage from the tablet there you will see a bunch of files ".android_secure,.br, android" etc,etc, there also should be a Folder called "Recovery" which contains the actual command that tells the tablet to do an update. inside there should a file labeled "command" and when you open it with "notepad" it should say "update_package=SDCARD:/update.zip" this what is going to tell the tablet to put a new ROM when you do the power up holding the power and the vol. + buttons, once you verified the "recovery command" is there, copy your "update.zip" folder to the same area where you see all those other "android" and "recovery" folders after that, power down, do the power up holding the power and vol. + until you see that it is replacing the ROM
Finally got my gtablet working with TnT lite, Market, Flash After getting confidence in doing this I then root my phone(Droid Increible) and install wireless tether so I can connect my gtablet to my phone. Thanks to XDA and the great members!
I have to say this is a nice upgrade from what it was out of the box, but my issue is spending 4 hundo on something I have to mod myself to make it work, because as it is now I have voided the warranty by doing this. Any other suggestion on tablets that are better than this?
we all feel you there..
Let me first start off by saying that I am on a Mac.
I used these directions to get my phone unlocked and get ClockworkMod Recovery or whatever running on my Nexus S 4G.
I then loaded Cynogen onto my SD card, booted into Clockwork, wiped my phone, then tried to install Cynogen. It failed- it couldn't install boot.img or something.
Now, when I try to boot up my phone, it just shows the Google logo with the unlocked icon below it. It never successfully boots. I can still get into Clockwork Recovery, but below every menu section over the logo, it always shows some error like
Code:
E: failed to something something /cache
Can you guys please, PLEASE instruct me on how to get my phone working normally? I don't need it unlocked, just running the stock OS.
Anyone who can successfully help me do this on a Mac will receive a nice PayPal donation if they wish.
Thank you so much in advance.
And yeah, I know I shouldn't have been attempting this because I am such a n00b.

What version of CWM did you flash?
Pm me and we will use a chat service (aim, yahoo messenger) and I will walk u through it.
My suggestion of what I would do is this. Find a windows computer somehow. Go to the development section and look for the sticky about rooting the ns4g. Look for the link to flash the d720 back to stock. Download all those files to a flash drive. Take the drive to the windows computer and set things up then flash the phone back to out of the box stock.
Then you can go back to the Mac and do the root and 3024 cwm recovery and rename the sh file that puts stock recovery back in at boot time. After all this you can do what you want but I would suggest staying with the stock experience. This might be extreme to fix this but in my opinion, I wouldn't waste time trying to fix it, especially since you are new to this. It's like computers, yeah you could try to fix it but you could be opening a can of worms. It might take less wasted time putting it back to complete stock instead of f-ing around trying to figure out what happened and how to fix it. You could take hours trying to fix an install of windows that keeps falling on it's face, or you could format and install windows fresh and new in maybe thirty minutes. Which is easier?
CM7 will not work at the moment because it still uses 2.3.3, go find instructions for a 2.3.4 Nandroid. if you want though,i heard that supeaosp works on a ns4g.

Dude, you can't flash regular Nexus S ROMs on the Nexus S 4G.
Reflash the latest clockwork recovery.
Use fastboot flash recovery recovery.img
then...
Go to recovery, mount the USB storage, and put this zip on the usb storage:ROM
Go to recovery and flash that zip
here's the recovery that works. cwm and stock. How many times is this going to happen with new people and this phone in this forum section before a new subsection is made? We are going to be putting out a lot of these unnecessary fires with people making first time mistakes until something is done so as to not confuse them. Some don't realize that there are different versions of the same phone that aren't necessarily compatible with each other.
The way things are set up now, it isn't making this problem go away. I think that a different method should be tried if the current one isn't working too well. I'm flogging a dead horse now......
I'm looking to root my new NS4G as well -- and do it right the first time. On a Mac as well.
If the similarly-suited OP had issues I'm a bit more skeptical about my effort.
A separate forum might be necessary so people with the D720 hardware don't have near-brick experiences.

Hi all,
Need help with my phone... :\
So I wanted to install ICS on my phone today (http://forum.xda-developers.com/showthread.php?t=1492957) and I looked at the instructions, obviously you have to have a stock ROM installed first before going for the ICS update. At this time I had CM7.1 installed. So I chucked the files on my SD Card to install (the ICS and Stock) and went ahead into clockwork recovery to try and install the stock ROM first. This didn't work, as at the time I didn't know you have to install it via the pink screen and extract the zip folder and put the dload folder in the root of the sd card. So when I tried to install it, it said starting installation, and then would say installation aborted, I had no idea why, so I tried another couple of times, still didn't work. I then updated my clockworkmod recovery to the latest version for the U8800 and it still didn't work (as I was obviously doing it wrong...). I also happened to have an update for CM7 on the SD card that I never got around to installing (7.1.0.1), and so I tried to install that and again it said installation aborted (not sure why that didn't work, should of...). So then I thought, that's odd, nothings working, betcha the ICS ROM won't install either, see if something else is wrong, so I pressed install... and it started installing... not exactly what I wanted or was expecting. So it seemed to install alright with no errors, so I did a reboot out of recovery. It then stuck on the white Huawei logo screen and just stayed there... some folders got created on my SD card (apps that I had installed on CM7), no idea why, it didn't seem to boot, left it for 5 minutes and still just the white logo screen.
So I then did some more reading and learnt that I needed to put the official ROM's dload folder to the root of the SD card and install it via the pink screen. I tried this, unpacks it fully and completes step 1, but it gets to step two, and 5 seconds later after it starts attempting to install the ROM it says, Installation Failed.
So I was looking around for people who had a similar problem as me, and found some, they found a way to fix it which was to put the dload folder in the root of the internal SD card, unfortunately I have no idea how to get to that when the phone doesn't boot up into the OS. I tried putting it in the internal storage via the pink screen, but that's only 200-250MB in size, and the file needs around 300MB, so there wasn't enough room. I tried repartitioning the storage hoping this would increase it, or return it to normal (as I had partitioned it before to the 1.42GB/1.12GB partition that others had posted up previously) and it didn't change a thing. So I have no idea how to get to internal storage D:
Not having fun so far... so I thought I might try and install CM7 again, and then go to stock, and then to ICS, or maybe just leave it on CM7 and give up for now. Unfortunately the version of CM7 I had isn't available anymore, and the newer version you have to have stock ROM installed first, so I decided to grab oxygen instead. Downloaded it and chucked the zip folder onto my SD card and tried to boot into recovery (Power+VolUp) and now it won't even go into that! It goes to the pink screen (Power+VolUp+VolDown) without any issue and I can connect to the computer and access the files on there.
So basically, I've bricked my phone and I would love it so much if you could help me get it back, I really don't want to have to go back to my old Nokia 2760 (http://www.gsmarena.com/nokia_2760-1975.php) where the speaker doesn't even work, so if I make/receive a call, I have to put it to loud speaker or headphones to actually hear their voice... would be much appreciated.
Thanks,
Gunny
I think you have some hope left if you can go in the pink screen mode. You should find some istructions from general section and Q&A section. If you can go to pink screen you should be able to install official Huawei rom.

I finally got it all sorted, if it wasn't for that pink screen, I'd be stuffed!
I had to go back to a 2.2.1 ROM before it would finally accept it and install. Had a bit of cache and corruption, but android eventually cleared/cleaned itself and put itself back to normal. Now I've got the official version of Gingerbread on my phone, and I'm not sure if I should upgrade to the official version of ICS or whether I should upgrade to Aurora's (http://forum.xda-developers.com/showthread.php?p=22682229#post22682229) version of ICS. Thoughts? And don't worry, this time I won't screw it all up!
Thanks all!
Alright, just discovered my official ICS ROM is for the U8800 pro, not the standard one, so I guess I will be going for Aurora!

No kidding, I don't live there either, but to help, we need some more information.
You are probably on the HC bootloader, which is why your roms won't install.
Check the bootloader Install sticky in the dev forum. You need to upgrade it to the V8 bootloader.
Then you can install the ICS and CM10 roms.

I have a similar problem. Bootloader V8 installed fine. But when I flashed different ROMs through CWM (install zip from SD card inside recovery), it hung at the screen "CZ's Bootloader V8, booting primary kernel" forever. Scratched my head for a couple of nights now, wondering what the glitch was. I even tried Bad Sector's V8 green. Same result. Help!!!!
Edit: I can still downgrade by flashing EUU (though not TD's V4, which installs fine but won't boot back up once I turn it off and on again???). Anyway, running HC 3.0.1 does make you feel like a Neanderthal. A clear instance of cruel and unusual punishment, I'd say. Even HC 3.2 won't stick! WTH?

Hello. Anyone? How about Mockba the Great? I'll do more than thank. I'll grovel at your feet (lol); or fly to your city vodka bottle in hand. Be compassionate and tell me something. Anything. Like my tablet is shot beyond salvage, so I can put it to rest. Why is it that I can flash EUU and use without problems but not any other upgrades? Is it possibly because of physical bad sectors lying in the path of data from the new roms (sizably larger than HC)? Or automatic remapping of NAND shot to hell? There's got to be some explanation.

I am not sure, but, I have the same problem. If I flash the EUU (Acer stock 3.01) , I can spend a couple of hours following the upgrade path all the way to ICS 4.03, then it seems no matter the boot loader/recovery combo I flash, I either end up stuck in APX, or I get the new boot loader/recovery, and the original Rom boots fine, but when I try to flash using fast boot I end up with the android on his back with the red exclamation.
It may or not be related, but the very first time I tried flashing a new ROM, I ended up stuck in APX, & the only way I could find to get out was to use Badsector. The next Rom I flashed left me again in APX, so, the first thing I went back to was BadSector, & it would not work. (Can't remember what the error was, but it wouldn't get far before stopping.) So, I tried APXFlash & it worked perfect. (Before I ran BadSector the first time I could not get APXFlash to work at all.)
Now I can flash as often as I want, but still can't get anything to work right. (Except Stock stuff????)

This is my guess: I was able to get someone with the right equipment to probe into the NAND and scan. The result shows random bad sectors all over the place. The scan lasted for more than a day without finishing, so eventually remapping could not be executed. If the capability of the NAND to remap is exhausted then depending on your luck, if the ROM data fits into good sectors, you get to use the unit. If the cache partition has black holes in it, you'll get errors and operational aberrations. If I'm right, then this is purely a hardware issue which will come back to haunt sooner or later. Makes sense?
Since the NAND is soldered onto the Main Board, there is little chance of replacing the NAND, if you can find one, that is. Darn it!

I had similar issue in the weekend, flashed Thor's JB romv17.....stuck on same screen as you, had a heck of a job getting things working again.....
So tdv4 installed without errors but wouldn't boot, is that correct? What screen did it get stuck at? With the earlier versions of timmydeans EUU u must boot straight to cwm and "fix permissions" in the "advanced" menu options (I think its in that option)
Other than that I can't offer u any further suggestions I'm afraid....

This gives hope. With TD V4, it stops at power on - power lights on (white LED), but screen remains dark. Thanks for sharing your experience, I will definitely try when I get back to it at the end of the month. So if I'm slow in posting the outcomes, you know why. One more favor to ask: what do you do after fixing permissions while on earlier EUU (I remember seeing that option somewhere in the recovery menu)? Should I proceed to flash V4, then move up from there? If I install V8 Bootloader while on V4's ROM, would that hinder further flashings in any way? Many thanks again. And what is going on now with your JB ROM? And Happy Thanksgiving to all the Yanks in here!
Ok, so here's a little info for you folks. Not sure if it helps you or not, but might clear up some of the mess that's been going on concerning bootloader versions VS Roms.
So you run one of the RUUs files. That's fine. Essentially you should be back on an HC bootloader running an HC rom. At this point, all your partitions should be back in place, especially if you used TD's tool.
While you are in HC, and everything is running fine, you should make a note of your current UID number. Because, after upgrading to ICS, your UID number will probably change. (the converted SBK number should be the same with both). But the RUUs seem to mostly want an HC UID number.
The issue, is when upgrading to ICS. If you do this the normal way via OTA, you should eventually get to ICS with a stock ICS bootloader. At this point, I would leave it alone for a few days, just to make sure it runs normally. Again, get your new UID number.
Now, here may be what you folks are missing.
With the introduction of ICS, Acer pulled a fast one on us. They introduced a little file called recovery-boot.p, and also a recovery.sh file.Both reside in /system (not sure exactly which folder for one of them, might be /system/etc or /system/bin.)
The issue, is that if you NVFlash V8 bootloader, and let's say Thor CWM 1.7.2 or 1.7.3, without deleting those aforementioned files, when you boot your tab, guess what? Hasta La Vista CWM, and mr android is on his back deader than a doornail. Not to mention you might screw up a partition or 2 along the way. And then it's back doing the whole thing again, sorta like groundhog day.
If you get Skrilax_CZ's bootloader running, then there's no real reason why you can't load a compatible CWM to flash roms.
Personally, I don't like the little 1-app-does-all. I prefer the old fashioned way. NVFlash from a command line. This way, you can see if there's errors coming up. Also, you may have better luck trying one of the older packages for the V3 or V4 bootloader. If you guys are interested, I can research my other drives in a day or so, and come up with one of the original packages. Am sure I saved it somewhere.
But if you get the V8 loaded, then you can boot it into fastboot mode. From here, you can fastboot a good CWM image. And at this point, I strongly advise CWM 1.7.2 or 1.7.3. After you fastboot it, boot immediately into CWM recovery. Do not pass go, do not collect $200, and do your wipes and formats and immediately install a custom rom. If you boot back into your stock rom, sianara..... This is why it's best to already have your custom rom.zip on your SD card.
Now, roms, kernels and bootloaders. The rom you choose to install, is pretty important. It needs to be recent, and designed for the ICS bootloader (V8). Using some of the earlier roms with kernels is asking for trouble. HC based roms WILL NOT run on an ICS bootloader. Remember that also, and vica-versa.
It's possible, however unlikely, that one of you may have unrecoverable corrupt data on your chipset. It has happened, but it's rare. Generally, you will find this when you can't get anything running. Period. Or in the case I know, the user could not migrate from HC to ICS. But only 1 or 2 people I know have had this. Oh, 3. I forgot Civato who totally cooked his internal memory (more than likely while inventing his own version of TWRP)
Wipes and formats. Again, I can't stress this enough. There have been issues using TWRP when it comes to wipes and formats. It seems, sometimes, things don't get fully wiped. So, as I always do with CWM, remember those versions I quoted), always
Wipe Data/factory reset
Wipe Cache
Wipe Dalvak
Wipe battery stats (optional)
Goto Mounts and Storage
Format System
Format Flexrom
As we say, be nice, wipe twice.....
Then install the custom rom (not a stock rom, remember the 2 recovery files?)

Thanks MD

Ok, so here's a little info for you folks. Not sure if it helps you or not, but might clear up some of the mess that's been going on concerning bootloader versions VS Roms.
So you run one of the RUUs files. That's fine. Essentially you should be back on an HC bootloader running an HC rom. At this point, all your partitions should be back in place, especially if you used TD's tool.
While you are in HC, and everything is running fine, you should make a note of your current UID number. Because, after upgrading to ICS, your UID number will probably change. (the converted SBK number should be the same with both). But the RUUs seem to mostly want an HC UID number.
The issue, is when upgrading to ICS. If you do this the normal way via OTA, you should eventually get to ICS with a stock ICS bootloader. At this point, I would leave it alone for a few days, just to make sure it runs normally. Again, get your new UID number.
Now, here may be what you folks are missing.
With the introduction of ICS, Acer pulled a fast one on us. They introduced a little file called recovery-boot.p, and also a recovery.sh file.Both reside in /system (not sure exactly which folder for one of them, might be /system/etc or /system/bin.)
The issue, is that if you NVFlash V8 bootloader, and let's say Thor CWM 1.7.2 or 1.7.3, without deleting those aforementioned files, when you boot your tab, guess what? Hasta La Vista CWM, and mr android is on his back deader than a doornail. Not to mention you might screw up a partition or 2 along the way. And then it's back doing the whole thing again, sorta like groundhog day.
If you get Skrilax_CZ's bootloader running, then there's no real reason why you can't load a compatible CWM to flash roms.
Personally, I don't like the little 1-app-does-all. I prefer the old fashioned way. NVFlash from a command line. This way, you can see if there's errors coming up. Also, you may have better luck trying one of the older packages for the V3 or V4 bootloader. If you guys are interested, I can research my other drives in a day or so, and come up with one of the original packages. Am sure I saved it somewhere.
But if you get the V8 loaded, then you can boot it into fastboot mode. From here, you can fastboot a good CWM image. And at this point, I strongly advise CWM 1.7.2 or 1.7.3. After you fastboot it, boot immediately into CWM recovery. Do not pass go, do not collect $200, and do your wipes and formats and immediately install a custom rom. If you boot back into your stock rom, sianara..... This is why it's best to already have your custom rom.zip on your SD card.
Now, roms, kernels and bootloaders. The rom you choose to install, is pretty important. It needs to be recent, and designed for the ICS bootloader (V8). Using some of the earlier roms with kernels is asking for trouble. HC based roms WILL NOT run on an ICS bootloader. Remember that also, and vica-versa.
It's possible, however unlikely, that one of you may have unrecoverable corrupt data on your chipset. It has happened, but it's rare. Generally, you will find this when you can't get anything running. Period. Or in the case I know, the user could not migrate from HC to ICS. But only 1 or 2 people I know have had this. Oh, 3. I forgot Civato who totally cooked his internal memory (more than likely while inventing his own version of TWRP)
Wipes and formats. Again, I can't stress this enough. There have been issues using TWRP when it comes to wipes and formats. It seems, sometimes, things don't get fully wiped. So, as I always do with CWM, remember those versions I quoted), always
Wipe Data/factory reset
Wipe Cache
Wipe Dalvak
Wipe battery stats (optional)
Goto Mounts and Storage
Format System
Format Flexrom
As we say, be nice, wipe twice.....
Then install the custom rom (not a stock rom, remember the 2 recovery files?)

Can't thank you enough MD, and dibb_nz too. Can't wait to get back to the tablet. Hopefully things will work out. When they do, I'll post the results for the perusal of similarly situated members.

This gives hope. With TD V4, it stops at power on - power lights on (white LED), but screen remains dark. Thanks for sharing your experience, I will definitely try when I get back to it at the end of the month. So if I'm slow in posting the outcomes, you know why. One more favor to ask: what do you do after fixing permissions while on earlier EUU (I remember seeing that option somewhere in the recovery menu)? Should I proceed to flash V4, then move up from there? If I install V8 Bootloader while on V4's ROM, would that hinder further flashings in any way? Many thanks again. And what is going on now with your JB ROM? And Happy Thanksgiving to all the Yanks in here!

Well after u fix permissions u boot straight back into cwmand flash the v8 and civatos cm 10 flex, which is exactly what I did after getting it up n running again. edit: no, u need the latest tdv4 - ...I'll post the link for it shortly....
I'd definitely uninstall the Acer drivers and reinstall them. When u connect to yr PC , windows will try to install the drivers....don't let it search windows updates, u have to be quick to cancel it....then it should install the drivers from the acer folder on yr PC which u just reinstalled....is that clear as mud, lol???
One more thought, u could get round all this driver business if u know linux at all....
But will w8 till u get a chance to spend some quality 'tab time'

So, this might seem kind of obvious, but I want to be sure. I found the Recovery-from-boot.p file easily enough, and I found a file called "Install-recovery.sh" in the etc folder, which seems to call another file called "system/bin/sh".
So, do I delete (or possibly just re-name??) "recovery-from-boot.p" and "Install-recovery.sh"? And do I need to do anything with the "SH" file in "system/bin"? (Like delete or re-name?)
Thanks for this much clearer (but still not 100% clear) info about these files. I had read mention of "recovery-from -boot.p" in another post, but it didn't make clear where to find it, just that you needed to deal with it. This excellent post makes it much more obvious which files & where to find!

Just those 2 files
This will prevent overwriting your custom recovery on boot.

I had similar issue in the weekend, flashed Thor's JB romv17.....stuck on same screen as you, had a heck of a job getting things working again.....
So tdv4 installed without errors but wouldn't boot, is that correct? What screen did it get stuck at? With the earlier versions of timmydeans EUU u must boot straight to cwm and "fix permissions" in the "advanced" menu options (I think its in that option)
Other than that I can't offer u any further suggestions I'm afraid....

I was able to follow MD's instructions and installed Re-Flexxx Rom. As to dibb-nz's advice, I couldn't find earlier versions of TD (there was a link that led to some silly software instead - hijacked?). So I reflashed V4 which after the first reboot took me to the setup part fine. However, a second reboot resulted in a dark screen with nothing doing. I tried accessing recovery in vain. I'm not sure earlier TD versions would yield differently. If I recall correctly, V4 only differs from V3 in that TD added XP drivers. Why the tablet behaved thus is beyond me. I intended this superfluous info as a warning to such possibility, however absurd it might appear.
Anyway, thanks to those who came to the rescue, and Merry Xmas to all.

can u provide a link 2 the tdv4 u used i will check it.....seems couple folks having yr issue, i wanna make sure the zip isn't corrupt...
ALSO: there are 2 ways to use the EUU -
1) as an upgrade tool - used to upgrade from one HC build to the next - just open and run with usb connected and
2) as a downgrade too - used to downgrade from the ICS back to HC - you run it by not connecting your usb cable and force apx mode
Im curoius as to why folks are getting stuck with the black screen - this happened couple months back too
and tho i have been stuck with it myself - i have never been able to replicate the issue..and believe me when i say i've done some crazy things with my tab in the process of trying... so would like to rule out a bad file...just in case its me causing all the problems, lol....feedback would be appreciated....

I'm almost sure I downloaded from the link provided in this thread, though I'd appreciate your not quoting me on it (lol). I remember downloading twice but cannot tell now which is which. Either way, I "upgraded" from HC 3.1 to 3.2, which is the version included in V4. Beyond that, I'm not sure what other information would help sort things out. Oddly enough, the first automatic reboot after flashing works fine and takes me through the whole setup process glitchlessly. It only happens on the following reboot. You can get into recovery 1.5, but fixing permissions won't do.

ok thanks for that - the v0-v2 required all sorts of jumping thru hoops to get root/cwm installed....when u finished the first flash you would end up with a LNX check sum error in red text on your tab and have to boot straight to recovery and fix checksum errors (not permissions as i said earlier)
v3/v4 now comes pre-rooted with cwm 1.5, which is what may be corrupting things if you are still have the v8 bootloader - altho in saying that, a few of us have been on HC3.01 with v8 and had no probs flashing a compatible ICS v8 rom from there...maybe it was just a fluke who knows...One thing I do know is you should really have a compatible recovery with the v8 - which is why all the flash packages come pre-loaded with a custom recovery....as MD said above you need to make doubly sure your rom/reocvery/bootloader are all compatible with each other. this applies whether they be stock or custom 'whatevers'....

and you have completed all the wipes as MD suggested, including toggling /data/media erase in cwm?
I realise you may have done everything correctly, this is more for the benefit of those folk "trying" to follow along
this is on 3.2?? you run the EUU ok, boot to android, and run thru the setup wizard, then the next reboot goes awry??

I was initially on 3.1 stock. I went to stock recovery which proceeded to erase whatever, then showed the android belly up with the triangle exclamation mark and so forth (The sd card contained no ROM at this point). I rebooted, then flashed V4 directly from inside 3.1 with debugging on. It "PASS" uneventfully, rebooted on its own to the setup wizard. Things function normally within that capsule (it showed HC 3.2 I believe). I turned it off after setup was done, then on again to experience the black SOD. I then went to Recovery 1.5, erase everything a few times, then rebooted. Same result. Eerily dead.
Then came the V8 Bootloader and Thor V20, and the tablet was resuscitated. Works fine now.
