Hi guys, i'm in desperate need of your help. i think my precious o3d might have been screwed.
first let me tell you what i did. as you know the internal sd card of o3d is 5gb or so and it fills up very quickly. this internal sd card is mounted as /sdcard. i have a class 10 16gb micro sd card and when i insert it, its automatically mounted as /sdcard/_ExternalSD. The applications or games, especially the ones that have external data folders which are like 1gb in size insists to be installed on /sdcard. You can't move those data folders to _ExternalSD, because then the apps doesn't work.
Then i came across this topic:
http://forum.xda-developers.com/showthread.php?t=1189701
As you can see that was exactly what i needed. I had CWM 5.0.2.0 installed so i downloaded the first .zip then copied all of the files and folders excluding the _ExternalSD folder to the external sd card then rebooted into recovery. From there i flashed the zip and rebooted again. phone booted up and all was ok and it worked. now the phone sees the external sd card as the internal one and the internal sd card was mounted as /sdcard/_ExternalSD. I then formatted the internal sd card from the settings menu because i already copied all of the stuff there to the external card. It worked fine and the internal card is formatted. After that i decided to get a nandroid backup so i opened the rom toolbox program. From the menus i selected the backup option, gave it a name, clicked ok. the phone rebooted into cwm recovery screen but nothing happened. then i noticed something was not right because there was some error lines under the cwm menus saying "E:can't mount CACHE:recovery/command" etc. Then i selected the reboot phone option but the phone rebooted right back into the CWM recovery again!! At that point i knew that i was @#?^ed.
Anyways i researched a lot and came across this thread:
http://forum.xda-developers.com/showthread.php?t=1156549
i did exactly what he said and it worked, i mean it flashed nicely. then i rebooted the phone but it booted into the recovery again!!! But this time the CWM recovery was gone and i believe this is the stock recovery screen. I can browse the menu of it and make selections but the phone boots into the recovery every time it reboots.
The recovery screen looks like this:
http://farm8.staticflickr.com/7010/6654644033_b616bc0635_z.jpg
Then i flashed the phone to the latest official firmware V21A_00, it flashed nicely but it still boots right into the recovery everytime.
Then i installed the Android SDK and tried to push the original vold.fstab file to the system using the adb command line tool but it doesn't see the phone. I think adb works only when the system boots up normally, not in the recovery mode.
I don't know if there's a way to install the CWM from the stock recovery somehow. If you know how, please tell. The CWM has more options.
I don't know what else i can do. It started to look ridiculous. If there are any experts cool enough to help please do so. I'll be waiting. Thank you...
Edit:
I also tried this:
http://forum.xda-developers.com/show....php?t=1244490
I starts just fine but get's stuck on the "RESET" command, after a while it gives "DOWNLOAD FAIL!" error. I think the phone is supposed to restart automatically but it doesn't. Manually resetting the phone doesn't work either.
I'm about to pull my hair out...
Edit 2:
I also posted on the official LG Mobile forum here:
http://www.lgforum.com/forum/boards...d-goes-into-recovery-mode-every-time-it-boots
Fingers crossed
Quite a post!
From all your post there is no mention that you formated and did a factory reset after 21a flash.
Can you please try that if you haven't?

thank you for the reply!
i tried all 4 wipe options on the recovery screen then rebooted. it's the same, i'm back at the good old recovery again
Did you try with the external sd card out?
This is strange, usually a kdz flash coupled with a format fixes the problem.
Some how it still can't find the internal SD card.
I don't have further recommendations. Sorry

Hopefully someone else on this forum can suggest a way for you to unbrick.
your problem is although you have reset your phone, somehow it can't find a partition to boot from.
or
somehow the KDZ flashing is not totally successful.
good luck
If only there could be a way to be able to use the adb command from the Android SDK then i might be able to restore the vold.fstab file to its original, if the problem is that at all. Maybe then it'll work. To be able to flash the CWM Recovery again somehow might be a good thing too because it has more options like flashing .zip format roms but i have no idea how. Does anyone know if the stock recovery can flash some specifically named file to the system, does it have that kind of functionality? I'm desperate, please share your thoughts.
.............anyone?
I am sorry to say that but there is no solution for this problem yet. I have done the exact thing that you do and tried every single solution with no luck. The only way is to send it to lg repair service. My solution was to replace the mainboard.
Dostum gecmis olsun malesef tek cozum yolu anakarti degistirmek. Uzaman sayilirim android konusunda bosuna ugrasmayasin diye soyluyorum. LG servisi bile anca anakarti degistirerek cozum sunabildi. Temel problem internal karti formatlamis olman. Partititon table'i bozuyor bu islem malesef ve bu yuzden hicbir yontem ise yaramiyor.
Gecmis olsun tekrar...
so you say that the main problem was to format the internal sd card? well if formatting the internal sd card bricks the phone then why the hell is there an option to format it in the settings menu?
well if you didn't apply the swap fix, it wouldn't be a problem to format. When you swap the sd cards and format, it is the problem.

so you did exactly the same thing as me right? i mean you applied the swap fix then formatted the internal sd?
replacing the motherboard to fix this seems to be a bit nonsense to me to be honest. what does the partition table have anything to do with the motherboard?
if only there would be a .kdz format custom rom which factory resets the internal sd card during the flash process and maybe fixes the bootloader somehow, that might be the solution.
yes i did the same and the only solution was to replace the motherboard. we need a sowftware that can reach to the emmc in low-level. like omap flasher. but we also need the correct drivers which doesn't exist yet.

i don't know what the emmc is, i need to do research on that. but i still think that replacing the motherboard won't solve this issue because it seems non relevant to me. i messed up with the vold.fstab file. but after that it worked fine. i mean the internal and external cards swapped just fine. only after i decided to make a nandroid backup using rom toolbox all hell broke loose. i plan to wait a couple of days before turning the phone to LG service. i believe someone will come up with an idea.
yardım etmeye çalıştığın için teşekkür ederim bu arada
Well, there´s a new recovery for the O3D, v5.0.2.7 (I got it with ROM Manager).
It fixes 2 bugs of the previous (5.0.2.0) version: now the USB mass storage option in the mounts menu works (mount external SDCARD), and we can use ADB while in recovery. That way we can fix stuff in the phone filesystem while in recovery: we can now use ADB shell, or ADB push to replace files.
The problem is that I don´t know how to flash it to the phone while in the stock recovery. If someone can guide me on creating a signed ZIP containing this new recovery, flashable in the stock recovery, I would be glad to do that and post it here. I think these phones of you guys can be fixed using this method!

Great news! But now i need to find a way to install the new CWM. Just as you said i believe what i need is to find or make a .kdz update which includes this new CWM.
What do you think?
I know this is possible, at least for the Galaxy Ace: I have a ZIP file for this device with a custom recovery image, flashable in stock recovery!
To make one for the Optimus 3D, I need to know the following:
- How can I obtain the .IMG of the new recovery? I have found some temp files in clockworkmod folder in my sdcard. The creation date of one of them matches the exact moment I upgraded my recovery, and the file size also matches a recovery image: 5.54MB. Is it the recovery image? Can I just rename it to recovery.img? How can I extract it to ensure it´s ok?
- After I get the recovery image, I can use the Galaxy Ace ZIP as the base to build the O3D zip file. Any help on what do I have to change to make it work correctly?

I am asking this again here, as my previous thread seemed to be hijacked by someone elses question!
I recently decided to root my inspire as i am no longer using it as a phone, so i thought that it would be interesting to do and fun to play around with all of the options available (i recently did the same thing on my Nook Tablet, and that was the single best decision i have made a while!). I started out researching the manual techniques to do it, but i didn't really like the high risk factor there (i really dont want to brick my phone) so i tried Ace Hack Kit. Of course, it has to download the phone from 2.3.5 to be able to work. During this process, it has me hold volume up and power twice, and every time i do that, it flashes up really quick something about holding volume up and volume down and power, but then it skips past that. Anyway, here is where my problem comes in: It says that it should reboot in to hboot, which it does, but that hboot should run a test, then prompt me to continue by pressing volume up, and then should reboot, flashing twice, and that should be the end of it. THe problem is, it does boot in to hboot, but it is just a standard hboot screen asking to recover, load bootloader, etc. When i reboot from there it just boots in to the phone as normal. I have tried 3 different SD cards, all of which work and are recognized by my PC, my other phone and my Nook tablet. I have also inserted a working sim card, just to be sure that wasnt the issue, and i still cant make it work. Does anyone have any experience with his issue, or any idea what i might be doing wrong?
Opening multiple threads on the same issue is frowned upon. Even if someone supposedly hijacked your thread. I read it and only 7 posts ,I'd call that far from hijacked.
Now at the issue on hand. As mentioned in the other thread. Its the SD card. Also their is a hack kit irc go there. Plus pasting the output would help aswell

OK, as i have stated, i have tried a new SD card (2, actually, with the same results.) as far as an output screen, there is none. Ace Hack Kit goes through the whole downgrade process, my phone gets in to hboot, but it is just a standard hboot screen, and it doesn't downgrade. When my phone restarts, it restarts like i just did a factory reset.
There is an output,copy what ever it says. There probably is something you missed
As too the SD card ,try adifferent one again. Your SD cards are corrupt and you need to find one that works with the kit
Also since your on a sense 3.0 did you do the changing of the boot img before running the kit?

by changing the of the boot img do you mean downgrading it? That is what i am trying to do. The kit is supposed to do it automatically. If that is not what you mean, please explain!
As to the output, copy thing, no, there is none of that. I have followed the instructions about 20 times. After starting the downgrade process, the phone restarts and comes up with a red triangle. At that point i am supposed to hold volume up and power, and it goes and reboots and i do the same thing again. At this point, i am told that the phone will boot into hboot and check the boot image. When it is done, i am supposed to hit volume up to confirm, and then the phone will reboot, this time in to the down graded image. That is where my problem comes in. Instead of checking the boot image, it just goes to a standard hboot screen. There are no error messages or warnings, and i have followed the instructions to the letter.
As far as the cards are concerned, the maker of the kit suggested a 2 or 4gb Sandisk series 4 or 6 SDHC card, so i bought 2 of the series 6 4gb, along with the 2 others that i already have. I also have 2 series 4 4gb and 2 series 4 2gb Sandisk cards, as well as an 8gb and 2 4gb PNY cards. All of the cards recognize in my phone and PC, and the older cards also recognize in my Nook (and were used to root and load custom roms on several other devices), i have not loaded the new cards in to any other devices besides my laptop and the phone for fear of corrupting it. So i find it difficult to believe that the cards could be the problem.
I know what the kit says. What I'm saying is In the command prompt it spits out a lot of info. For example it will say stuff about zergrush and or taco root. THATS the important stuff, this is what is used to allow the downgrade to be possible. If their a failure in the process it would state it there. That's why I keep asking for it. Don't understand your reluctance to do a simple copy and paste
The changing of the boot img is something that is different and you should read about it on attn1 site. Version 3.20 has a slightly different method

I appreciate the attempt to help (the reason why i didn't post a direct copy paste was simply as i was in no position at the time to take one, not any reluctance to ultimately do so...) In my recent attempt to provide you with a full copy paste of the process, i was able to figure out what i was doing wrong. For anyone who may have the same or similar issue: format the SD card while it is in the phone from your PC right before starting the process. Thats all it took. Even for a card that was brand new and untouched, or formatted before putting it in the phone, i couldn't get it to work, but it worked doing it that way, and i am now happily rooted and ready to install CM9!
Glad you got it figured out. Formatting the SD card in the phone is a must, since the phone puts important files on the card after formatting.

Wrong. There's no need to format the sdcard to run the Hack Kit, unless your sdcard is not in fat32 system file format. The only requirement is that your sdcard must not be corrupted to work as a goldcard. Corruption of the boot partition of the sdcard can not be solved by formatting and is produced by improper dismount of it.

I'm just speaking from experience. Every SD card I've put in my phone I had to format in the phone because it was giving me problems. After, no problems. Maybe it's just my phone. or the cards weren't FAT32.
You're last sentence is probably where most people screw it up. You can't just yank an SD card out of whatever device it's in, which I think a lot of people do. But I have fixed cards that were removed without unmounting by formatting. Maybe other parts were corrupt but not the boot partition?

As far as I am concerned the boot partition can not be restored by formatting. SDCARD should always be dismounted properly.
Hello everydody, I am experiencing some difficulties with my Samsung, model GT-I9003-phone which "dropped off a lorry" somewhere next to my relatives somewhere in Asia. When I goth the device, it was in a non-working condition, except a boot-loop and the download-mode. Back then, I had the package of the phone where the exact version ( I don't know if this is what is called "Baseband" or at least is called baseband at my wife's GT-I5003) was specified. So, back then, I was able to find the exact ROM for the device. Unfortunately, the box with the version number now is - somewhere.
After flashing a stock-rom, I managed to enter recovery-mode where I read something about the internal memory being corrupt. As far as I can recall, I then mounted the external SD-Card and somehow managed to reboot the system back to almost normal operation. Even reboots appeared to work normal, besides the fact I had no memory access, neither to internal nor to external sd. In addition, GPS malfunctioned, too.
Unfortunately, even this state didn't last for long time. After several weeks of now-and-then-use, the system just broke down again into a boot-loop. After some time of flashing a variety of stock roms, I managed to flash clockworkmod recovery which works perfectly well. Unfortunately, I didn't manage to root the phone before it "collapsed" again. Besides the possibility, I'd guess this could be a resaon for CWM being unable to flash a custom rom? Otherwise, I'd just test my way through the varieties of versions .
Basically, I do have two questions: 1. is there a possibility to find out if internal memory has failed - and if yes: How?
2. Is it possible to install any version of CM on that phone in the condition it is in?
Thanks a lot in advance for any answers
Hello everybody, I finally found the box . It reads GT-I9003MKDTHL. Is my assumption right that there are no such things as basebands in the GT-I9003 any more and I should be able to flash pretty much any firmware? Furthermore, today I tried to format what is specified as "sd-card ext" in CWM fir GT-I9003 and it gives me an error-message. When I flash "sd-card", my external sd-card gets formatted. So, I'd presume the internal sd is just fried. I read about a workaround for GT-I 9000, where someone installed Androd on a partitioned external SD. Is there somebody who knows someboy having heard about somthing similar working with the GT-I9903?
One step forward...
Hello everybody, I finally managed to get some light into my issues as I once again figured out how to get a software installed and running . It's this one:
http://forum.xda-developers.com/showthread.php?t=2329200
Thanks a lot to the guy who just posted it somewhere where id could do good...
By the way, I figured out that this software actually includes the Baseband.
As in this version, the original recovery system is running and giving me an error message when I start it without external SD-card, I am now quite sure that the internal memory has just failed as this error message was specified in another posting of someone who had a similar issue with a GT-I9000.
The biiiig "Outch" is, that I am unable to install any CWM Recovery System with that Baseband..This results in me not being able to upgrade the software to ICS, where - as far as I read some troubleshoot-information - will enable me to mount an additional partition on my SD-Card as Data-Partition which isn't possible yet (i.e.: I can't access my SD for storing data or whatever - it's just specified as "not there").
I tried to install the XXKPE-Baseband to be able to go for KPQ which would enable me to install CWM Recovery. I also installed Bagarias CWM-normalboot-image via Heimdall - but I was unable both to boot the OS and to find any trace of a zip-file on the SD-card.
Edit: I managed to install the right CWM - it's mentioned in the post where I've got the firmware from... now, I only have to figure out how to deal with the fact that "officially" there is no SD-card inserted - or, better, that this SD-card is now flagged as "internal SD" - and how that machine can find the zip-file on it
Thanks for every bit of help with that issue
Try Aroma File Manager with Terminal
For SDCard issue you could probably switch them in vold.fstab in /system/etc

right now I can access twrp 2.1.8 from a bootable sd card and it'll run any rom thats put on the sd card we just want it to operate the way its supposed to
Ok, I have searched high and low to try and solve this issue without having to post it on the forums. There are several old threads about the Micro SD having issues here, and many many more across the net. At any rate let me start from the beginning.
So, I decided to root my stock tf300t and try the KatKiss 6.0 rom. Micro SD working excellent at this time. I also installed TWRP recovery image 3.0.2.0. Then for some simple reason ( read it somewhere) I dropped back to TWRP 2.5 and Micro SD still working excellent at this time. So, everything is great up to now.
I had found out that I had not formatted to f2fs and somehow with my big hand while doing so on the bootloader screen my pinky brushed the wipe data button. Yep, I lost it all and was stuck in the splash screen or TWRP 2.5 If I booted to recovery. My Micro SD and my TF300T's system files (all of them) showed 0mbs across the board. My file partitions were a mess to say the least. --- I posted about it in another thread.
Finally with the help of forum member gs-crash-24-7 I was able to flash the factory rom back to my TF300T and got my tablet back, with the exception of the fact my Micro SD no longer shows in my Tablet or on my pc when plugged in via the data cable. Now when placed in a card reader on the pc all my files were shown on the MicroSD< so I saved them elsewhere and using SDFormatter did a complete format and complete overwrite. (currently in fat32 mode - but have tried them all) Put a file on it and the pc reads it like a charm.
So, I went installed KatKiss 6.0 again in hopes the MicroSD would magically show up, also installed Kang TWRP 2.8.7.2, pico gapps, and supersu 2.52 to gain root access. But to no avail, I still have a Micro SD card that works great in my Galaxy S5, TF101, and my pc. I tried several different Micro Sd Cards as well, from a 128mb to 8gb one, which is the card I use in the Tf300T.
Ok, throughout my search of the net I found a similar issue that had been solved by adding a few lines of code to their phones permissions/platform.xml file. I have not tried this (honestly it was late and I forgot to bookmark where it was posted. lol Anyway, I did however go into my platform.xml file and did not find very much code in there at all and nothing mentioning External Storage R/RW etc etc ..... so Now I am wondering if I should revert back to JB 4.2.1 and start over in hopes it will restore my files and Micro SD. what are your opinions????? Open to suggestions.
Or if someone who has an Asus TF300T with a custom rom or factory rom (with a working MicroSD, could possibly take a look at their Platform.xml file and see if what is mentioned in it about External Storage etc .... I really feel like something somewhere that got deleted/wiped was not rewritten during the unbricking of my TF300T.
I Thank you in advance for any help or suggestions you may have to offer.
Flash back to stock 4.2.1 JB and still the card does not show up when inserted.
If I add the following lines into my system/etc/permissions/platform.xml file do you think it would bring back the ability to see my External Micro SD?
Code:
<permission name="android.permission.READ_EXTERNAL_STORAGE" >
<group gid="sdcard_r" />

Anyone ever try this?
BTW, my Micro Sd was working just fine in the tablet until the accidental data wipe. I am stuck here, I would really like to get the ability to use the Micro SD card/cards again.
Thank you in advance.

It seems there is an unknown issue remaining after things you have done in the past. Please start your TWRP and "Format /Data". It may take one hour plus. Wait patiently until it finishes. After that your system is clean. So you can clean install the ROM of your choice. Simply follow the install instruction given by Timduru carefully!!! Finally the SD card issue should be solved.
Thanks will give it another try.
Several attempts at this using the latest stock rom and my own twrp backup (from when the sd card was showing up) and still not showing up. Tried to change files system in twrp and got this e:block device not present, cannot wipe ext_sdcard .... only close reference I found so far was in the following thread and according to post #16 my sd card partitions are not correct???
https://forum.xda-developers.com/tr...kang-twrp-tf700t-2-8-x-xarea51-t3049395/page2
also, according to twrp manager:
Storage Info
External SD Location
/Removable/MicroSD
But of course it does not show up in file manager. Thoughts?

This thread deals with Data2SD. That's not your problem. The SD card should be FAT32.
However what's the result of Format /Data? Has it been accomplished successfully? Does your TWRP finally show the external SD card?
No, I have yet to get it to show any SD from 128mb to my 8gb card, I have tried them all. The card is formatted in fat32 (I have tried all formats though). The only time TWRP seems to see it is if I want to fix or change the file system, (now when I was in twrp 3.0.2.0 was the last time it worked) TWRP shows it as vfat. If I try to change it I get the error string below (red text).
All of this started when I corrupted the partitions in the tablet and had to flash a factory rom on to get it going again. Since then no SD card, well actually no SD card while it was corrupted either only before the mess I made.
I feel confident that the SD card issue has something to do with where it's actual path or permission might be placed or written. As the card works excellent in my galaxy s5 and Tf101 and Windows. just not the tf300t. Attached several images maybe one of them will give a clue. Keep in mind under mount, when I choose the Ext SD it just greys out and will not accept a check mark for selection, same when I choose where I want to install a file from.
Again thank you for your help.
Well I have tried going back to the latest stock rom and now I am flashed to the latest KatKiss 7.1, but still no luck. is it possible that somehow when I messed up my file partitions that it, that they just will not clear up completely for some reason? Grasping here I know.
This happened to me and I am still currently dealing with this. I believed that there is a problem with that device recognizing the SD card, as in the card is not making contact with the device. The SD card comes up as corrupted when the ROM is running. I had to side load the last few time through TWRP to get a new ROM flashed because I wiped everything. On this last try I was able to get the device to recolonize the SD card by pushing and hold the SD card all the way in and holding it there for the duration of the flash. I went through all the same as you did including flashing back to stock. Sorry you are dealing with this.
Thanks, I will give that a try also when I load my next rom.

Tried the hold the Micro SD card in deal, didn't work for me.
So now I am currently on a clean install of KatKiss 6.0 with same results. Micro SD card not being recognized.
My install process:
Wiped everything then formatted data
Even fastboot erased everything again just in case via fastboot:
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 reboot bootloader
Flashed KANG TWRP 2.8.7.2
Wiped davlik and cache, then changed data to F2FS file system
Rebooted to Bootloader then entered RCK / KANG TWRP where I did a TWRP BACKUP (it will not backup I know this) so I would have the TWRP folder it would create, so I could load my zips etc, once I was no longer in fastboot. Once in Twrp, you can see internal files then like the TWRP folder, where transferred my zips via the pc to. (now I have a place to load them from)
Loaded the Micro SD just in case with my zip files and also copied them from my pc to the TWRP folder in tablets internal storage.
disconnected from pc and loaded MicroSD into tablet slot.
rebooted into recovery (TWRP still would not load Micro SD ... so plan b) from internal storage via the TWRP folder that was created I flashed all my zip files together:
Flash KatKiss 6.0 rom
Flash the SuperSU 2.52 zip
Flash gapps nano
Wipe cache/dalvik
Reboot
Everything was done per Timduru's instructions, except where I had to load my files via the internal TWRP folder, and I use the Nano gapps over the pico. Also, one tablet reboots to the system i updated the SuperSu Binary.
Some of the Erasing was probably overkill, but I was trying to clean as much as I could in hope my Micro SD would show back up.
Tablet is working fine, in fact very fluid and speedy. I just do not have access to my Micro SD card, except via a usb adapter when used on the pc, which does me no good lol.
At any rate If you do not have a Micro SD card, maybe my process will help someone do a clean install at least.
I hope a solution appears. I just upgraded from cyanogenmod 4.4 to katkiss 6.0 today, and have the same problem . microsd was there for the install, but after booting, ES file explorer doesn't see it. Can see the usb drive plugged into keyboard, but not microsd. frustrating. was thinking of trying to reflash everything but what I am reading in this thread, it seems like that won't help. (btw, there was also issue of tf300 not rooted after install. I reflashed superSU, and after a few reboots and attempted binary updates, suddenly root appeared. I don't know really what fixed it)

What version of TWRP are you running? .... I also had a problem at first with root, but none since and I have flashed every katkiss rom and my back up of JB 4.2.1 and even the fresh stock Asus JB rom with no success as of yet. But I have yet to stop messing with it, going to keep on til I break it, fix it or possibly shoot it. lol
Also, mine still does not work at this time. I actually went online with lj50036 and went through lots of force load commands etc etc and it still never showed up. Crazy thing was at one point it was showing I has 2 Internal Storage folders both with the exact same file size and files within it. I suppose there is a possibility that the card slot stopped functioning in my tablet, but I just keep coming back to my original issue before the card disappeared (corrupted file partitions). I don't know why, but I just feel something somewhere is still fubarred with the file partitions dealing with external storage. Plus with all the research I have done on the issue and such close to it, there seems to be an issue with happening with many devices and custom roms and recovery.
I wish you luck and if I do find a solution I will most definitely post it here.
Issue solved:
Turns out one of the SD Slot connecting pins was broken in the back of the card slot. Oh well, at least it's a 32gb tablet.
Many thanks goes out to Josh lj50036 and the others who tried helping me.
I installed (4 th install, 3 with 6.1) kat kiss naugetella, 7.1. microsd card is now seen. I have no idea what was different about this install other than the 7.1 and different supersu, version 2.79.
still not having keyboard recognized during sleep. previously I could wake the tablet by hitting the keyboard sleep key. No more. have to use the tablet power button.
