3588 running enhancements. running great for weeks. Tonight was using my tab and noticed that the battery was getting low. I powered it off, plugged it in and set it on the night stand. 10 minutes later I wanted to check something on the Internet. I turned on the tab and got several errors. magic value mismatch, bad boot device, and some hex addresses I didn't write down. I tried power/vol+, it looked like it was restoring then failed. In the end all I got was magic value mismatch. First thing I did was come here search in magic value mismatch and found posts on NVFLASH. I got the files, performed the flash and all appeared to go well. When the tab rebooted all the tapntap windows were blank. No big deal I always used classic UI anyway. Immediately I got the notice that 3588 was available. I told it to down load and apply. After the update, my tablet shut down..... Completely. It will not respond at all. Power button does nothing, power /vol+ does nothing. Any suggestions?
Did you try holding power and vol- ?
Also, you can hop in the #tegratab IRC on Freenode and more people can help you.
Yes I did
I did try power/vol- nothing happened. I was however able to do the nvflash again. It get's me back to the blank tapntap. I told it to do a factory reset. Now it will not turn back on again. Seems the only way to get the thing back on is to reflash it.
Found the problem. Corrupted system.img. Re-extracted nvflash_gtablet_2010110500.zip and sizes were different. Reflashed, and all is well. Still no idea what caused the initial Magic Value Mismatch.
Have you tried flashing a different ROM?

I hate to say it, but it sounds like your tab is doing something simitar.

It was a simple system.img corruption. He re-downloaded it and it worked fine.

Alright, allow me to summerize to you guys the series of screw ups that happened in the day that I've had my captivate.
Basically, it's like this. I got this phone from my brother (it used to be his). Now when I got it, I began basically erasing his contents and setting up mine. The Phone is on the Cognition OS and everything seemed fine.
Now, when I tried to set up my google account, it said I had to do a factory reset, I did that. Then I realized the market place app was no longer there :/
I did another factory reset, still didn't help, and started looking around for info.
I told my buddy this and he said he could fix it. So he get's the update.zip for rooting the phone, sets it up on the SD card, and goes to root the phone normally. Except when he restarts the phone after, it doesn't go to the set up screen, so he just starts it normally and enters the setup screen by holding home+volume up+power.
Then he presses the reinstall packages, and the phone seems to get to work on the update pack...
Now, every time I turn on the phone the voice says "converting data partition to optimize extension four", turns off, then repeats.
I've looked up this problem and it seems to have something to do with voodoo, but the causes in the other cases the causes were different.
Can someone please help me out here? I've also tried doing a hard reset by holding the volume down button and pressing power, but nothing seems to take me to the recovery mode.
HELP.
Did you pull the battery during this our did you let it run? Should let it run.
Does your phone boot up at all?
At&t or rogers?
Do you have a windows pc with usb drivers installed?
What its your build number, located under battery, something like 1008?
Answer these questions and we can get you back up and running
-Well after he did the reinstall thing we let it run for like 15 minutes, then he pulled the battery out.
-The phone only shows the AT&T screen, say's the "converting data partition..." thing, then goes blank and does it again. I've let it run for like 10-15 minutes before having to turn it off because I couldn't have the speech going off.
-I have a windows PC, and but I'm not sure if I have the drivers installed. I have Kies installed and when I plugged the phone in before Kies could recognize the phone (though it wouldn't fully connect, it would just say "connecting" on the kies screen).
-The Model is SGH-I897, that's the only relevant thing I see under the battery, that good enough?
Thanks a lot.
No, your phone has a build, on phone under battery, the word build is not listed. Something between 1006-1012
If we are going to do this you need to be active, I can not wait 20 minutes in between responses
Sorry the internet kinda crapped out actually.
And I see a 1007 between the bar codes, that it?
Yes
Before we get started try this
Take battery, sim, ext sd our of phone
Plug usb into pc but not phone
Put battery back in
Hold volume up and down, while holding plug in usb
Screen should come on with android with shovel
You can pull the battery again
Confirm this happened
Yep, it happened.
It may be easier if we use gtalk, log in on your pc using google id, send me an invite [email protected]. This way we know when each other respond

Have you gone back to stock and then reflashed? Seems like some files are getting corrupted. Because you have a voodoo kernel I would follow these steps. Make sure to back up.
1. Use Odin to flash a non vodoo kernel.
2. Flash stock rom and master clear
3. Reflash rom of choice if it is 2.2
3a. If you want 2.3 follow the tut on it.
4. Breath a sigh of releive lol
So I've had the G-Tab for a month now (stock 1.1) and decided to change the rom to Vegan-Tab and followed these steps.
1. Installed CWM fine no problems.
2.Repartitioned, again fine no problems.
3. Tried installing Vegan-Tab appeared to work fine until after re-boot the tab got stuck on the three birds.
4. Realised I should have run NVFlash before installing new Rom so ran NVflash, again appeared fine until re-boot. This time I was not able to turn the Tab on (Power Button not working)
So now the only way I can turn on the device is to run NVflash (tried with and without CWM) and leave it on all day.Power button works fine for entering sleep mode or for turning Off but just will not turn the Tab on. Any time I try to install a new Rom I get through all phases until the re-boot, then nothing. Guessing I am maybe stuck in APX but how do I fix?
Yes... you're in an APX loop. Try the following...
1) Do an nvflash to start it up and immediately do a datawipe. If the resultant restart doesn't fix it...
2) Goodintentions has a GTablet for Dummies website with known good nvflash images. Follow his instructions carefully.
3) If none of that has worked... Sometimes the only way out of these loops is to force the tablet to reload a stock bootloader. The following procedure will do that:
http://forum.xda-developers.com/showpost.php?p=13474033&postcount=114
This guy has already tried all those tricks. I was the one who sent him here. Anyone else know how he could fix his gtab? I ran out of ideas.
If that's the case I'd be interested in seeing it. Ive never seen one that failed all of the above... Perhaps a hardware problem?
Logs would help...
Any error messages during nvflash?
Any other odd behavior?
Be happy to help if you can supply more info.
Hey, yo, try my new code detox in the home page. Can't believe I forgot about that.
http://viewsonic-gtablet-for-dummies.webs.com/
Thx for your input guys, especially goodintentions. Ended up contacting Viewsonic and sending unit back. If they repair/replace it great, if not and I get it back I will try your detox. Either way next time I will follow your directions to the letter and won't get carried away this time. I will also be sending a donation/beer money your way! You guys are great for us dummies.

Will VS replace the unit even though you flashed a ROM to it. I was wondering if I should send mine in. I NVFlashed it and now I get nothing. no screen, no recovery mode, no APX mode. It is not recognized by Windows when plugged in nothing but that little red glowing light when I plug in the power jack.
If you can't turn it on, then they can't turn it on.
I'm guessing what you have is a hardware issue. Just a coincidence that it happened as you flashed in something else.
I suspect it's a software problem and not related to the hardware models. We have htc inspires though.
Wife and I have identical phones. She came home from work and told me hers crashed; she said she charged it on her way in to work and when she reached to use it saw the root/boot/recovery/whatever screen. (She described it and then when it came up when I looked at it, confirmed that was the screen she'd seen.)
We've got android 2.2.1, if that helps.
Anyway, the phone crashed and won't restart. I pulled the battery out, waited, and popped it back in, and nothing happened. Pulled it out, waited, popped it in, tried the method described here *edit: apparently too new to post links. it was at the htc community.* of trying to bring up the recovery menu. Looks like we have fastboot enabled, which a mod describes as being a known thing. I do the keystroke method as described here, and it brings the menu with the 4 options - reboot, recover, factory reset, and something else, but it doesn't let me navigate with the volume key the way the site and the bootscreen on the phone tell me I should be able to.
So - what went wrong, how can I fix it? I'd rather not have to schlep out to an AT&T store if I don't have to, especially if we can figure it out here. I'd rather not have to do a factory reset, as probably nothing is backed up or saved to the sim, but at this point, I'm worried that's not even an option I can select.
Cliffs:
1. Android phone crashed and won't reboot.
2. Can't make selections in the boot menu using the volume key as I'm supposed to
3. Phone runs through fastboot and fails to start up - I tried the thing I'm supposed to do in response to that as described here *edit: apparently too new to post links. it was at the htc community.*
4. This should be an easy fix / probably something someone here has encountered before.
edit: Don't know if this means anything diagnostically, but while the phone should be fully charged right now, it reads as at 0% when I plugged it in. I figured the utility that measures that probably isn't available at this level in the start-up?
edit2: She mentioned just now that it looked normal when she got up for work. Was at work and tried to use it but it was in airplane mode and she hadn't put in airplane mode herself. She clicked the airplane mode icon to switch out of it and the icon animation just sort of hung. She put it back on her belt like that, it sounds like. When she picked it up again it was in that root menu.
We're not rooted, and these should be vanilla installations.
If this is the wrong place to ask about this, can someone direct me to the right section? I wasn't quite sure where to post this. I reviewed the instructions and did a quick search... but my search-fu might suck.
So heres the story....wife has had lg g2 since it came out with 0 issues. About 3 days ago the phone starts doing some crazy ****, flipping through screens by itself, opening and closing apps, deleting things, rebooting, changing system settings. This was after earlier in the day she had downloaded some random games for my son to play (not sure if this was the cause/is at all relevant, just trying to be as detailed as possible).
My first though was that one of the games may have had some virus/malware **** going on, so did a factory reset. The reset was successful, however the issues continued. Next though was to root/unlock/install custom rom. (I have done this to all my phones, with minimal issues, so i felt fairly confident in doing so) So i rooted, installed twrp 2.7.0.0, and flashed this rom - ATT-stock-rooted-D80020K.zip - and all seemed well. Phone booted and behaved normally for the rest of the day (12 hours or so). Plugged in charger, went to sleep.
Next morning, wake up, grab phone, and its showing the LG logo (like when you first power it on). Restart (power button long press) and it boots into TWRP, and i go looking for the rom file to reflash, and its gone. All files are gone. In the file explorer in TWRP, i can see the files,(data, system, boot, and so on) but when i click on them there in nothing in any folder. All downloads gone. Everything.
But i can still get into TWRP, so i thought ok, ill just plug into pc, mount the phone, copy appropriate files, reflash rom, and all will be good. WRONG. I cannot get TWRP to mount the phone, and at this point ive got a pretty expensive paperweight.
All my unlock/flash/root experience has been on HTC devices up to this point, and i have never had an issue like this.
If anybody can advise what to do next, Im listening. Ive exhausted my knowledge on the subject at this point and NEED HELP PLEASE.
Thanks in advance.
Good day, this would be a pretty lengthy post. I'd like to describe my experience clearly since I don't know what I possibly skipped over as I am very positive that my efforts have been correct basing on prior XDA forums. I even made this account solely for posting this to ask for help formally along with archiving this problem I'm having for those having a similar experience.
I've been working on my mom's phone this whole day and there are fruits of my current hard work. I am immensely stressed and despairing with my situation.
The Problems
Infinite boot looping
Can't access the recovery menu (power, volume+, even with home button)
Can access the ODIN / Download menu
Can't turn off either (holding down power button has no effect)
What I've done so far
I read XDA forums about similar experiences. Can't really access the recovery menu so I've factory reset.
We live in the Philippines and this phone is open line, so I went with those requirements while searching stock ROMs.
I downloaded the stock ROMs of the phone model via galaxyfirmware.com which was positively shared in the forums.
Did trial and error with it and eventually got the right one. I have formed a level of understanding with the filenames and eventually knew which is compatible.
Used Odin3 to Flash the BL, AP, CP, CSC, and even go Nand Erase and got the PIT file inside the CSC (Opened it using winrar)
The flashing is actually successful and quite fast to be honest.
The phone reboots itself and shows that it is still sadly boot looping.
Also, despite the several files used for the Flash, still can't access the Recovery Menu.
With that said, I have also tried using Frija which automatically downloaded the stock ROMs based on the model name and CSC type. Placed it in ODIN again and no changes, still boot looping.
I also can't put the TWRP I got here because of the FRP Lock, which can be undone via the settings of the phone. But since it's boot looping, I can't really do much about installing a custom ROM.
Currently, my dad is letting the phone drain its battery, since we can't really turn it off. The phone model doesn't have easily detachable battery as well, unlike the old days.
For some additional notes of what happened prior to this incident
My mom was just playing with her phone as her usual days went on. That day, she installed a new hotel-themed game she saw on Google Play. As I assume that it's from the app itself and not on some shady apk website, I saw no problem with it and didn't think it was the cause of all this. I went with the theory anyway and with the flashing, using CSC instead of HOME_CSC (which apparently saves the existing data on the phone from wiping), and even used the Nand Erase in the end. It's still stuck at boot looping.
I would appreciate anyone's reply to this discussion. I am truly desperate to fix this for my mom. If worse comes to it, I'll save money to buy her a brand-new phone.
You don't have a working android, so you won't remove the RFP. TWRP will not help you with this.
The symptoms you describe indicate a defective power button.
You manage to enter download mode because the power button is constantly on.
Because of the constantly on power button, you have no way to turn off the phone. Bootloop can also be the result of a constantly on power button.
To sum up, you should fix the power button.
1. The easiest way is to blow with compressed air and press the edge of the button with your fingernail, rapidly releasing the pressure. Perhaps the fuzz has blocked the button. Unfortunately, this rarely works.
2. Take the phone to a local service center.
Hi ze7zez! Me and my dad greatly appreciates your insight and we were definitely enlightened on this angle.
We didn't really think that the power button was stucked pressed on because you can clicking sounds when you press on it. The phone never had problems with the buttons along the 6 years it accompanied us, perhaps its age does start to show.
We're going to look into it tomorrow. Thank you very much! You gave us the idea that it may be shorted inside or some sort. Thank you again!
A bit of update.
I pried open only the back case of the phone so I can see and clean up the power button. I used tools specifically for it and made no damage on the phone during the process.
We couldn't really see anything busted from there. The buttons on the circuit still do the neat clicking sounds on it. Battery still looks the same.
Testing out the theory that the power button was stuck on:
We tried to only press and hold the volume down and power button. It didn't go to the download menu. We needed to press down all three together to access it. It is confusing since we believe it would be a power button issue too, as the phone instantly turns on by itself when plugged to a power source (it's completely drained by now and we still can't turn it off manually)
Perhaps it's an internal circuit problem with the power button? It's confusing with the fact we still have to press on it to access the ODIN menu if it was like "on" the entire time it's looping.
Thank you in advance for further insights.
Try restarting by pressing home, power and volume up all at once.
Hi Pranav2406,
I have tried that as well in order to access the Recovery menu to factory reset, but no luck.
We have given up on repairing the phone and went out yesterday to buy a new one in a rush.
We will still send this broken phone to a repairman.
If he fixes it, I'd ask what he did on it so I can post an update on this problem as well.
It's better to let the expert troubleshoot it.
I do suspect the problem in the phone's hardware. I'm pretty confident with all the stock ROM flashing I've done so it's not a software problem.
Thank again for everyone's insights.
Perhaps this case is too much for an amateur to fix.
