Recovery is gone

I have searched the threads and have not been able to find a problem like mine
I modded my Gtablet with CyanogenMod 6.14b and have also installed the Gapps and all is working great!. But I wanted to do a image backup so I powered off and then using the Pwr VOL+ keys to try and enter recovery. I get the "android" text on the screen for about 15 seconds and then it just boots into cyanogen. I have done the following but to no avail
1) copy new clockworkMod Update.zip and recovery folder to root of MicoSD
no luck
2) same as above, but to mtn/emmc (What Cyanogen now calls Internal SDCARD)
3) Changed the value in command file from --update_package=SDCARD2:\update.zip
to
--update_package=SDCARD:\update.zip
I also noted that there are folders EMMC and SDCARD listed under "/" as well as under "/MNT" they appear to be the same. Is this normal???
No mater what I do, I cannot get into recovery Mode.
Any help will most likely get you into heaven
Success!!!! Was able to restore using the recovery.img in clockworkMod Many thanks to ngorgi and ReoBeet for the help.

Did you use the clockworkmod specifically for our device and the one I use, which is .08? It sounds likely, but I wanted to confirm that.
Assuming that you did and that recovery is borked, you won't be to fix it the normal way since there's no recovery to flash recovery (if that makes sense). You might have to try either flash_image which a few people have suggested might work, or nvflash. I personally have used the latter.
If you can get APX mode working and get bekit's nvflash setup working, you can just flash partition 9 with bekit's recovery.img and that might work. I have a post on nvflash here: http://forum.xda-developers.com/showthread.php?t=861950

i Used the .08 as your surmised, My question is how did the recovery get lost?
When the PWR + VOL+ get used to enter recovery, what file is executed?
It took me several days to configure my tablet, it would be a shame to lose all that work.
But If that is my only option, then NVFlashing I will go

Try to change the value in the command file to...
--update_package=EMMC:\update.zip
Might do it... you can't point it to SDCARD unless you place the update.zip on an inserted Micro SD Card.

I'm not sure how your recovery is borked, but I'm assuming that it is. You can use nvflash to just flash recovery and nothing else - technically you shouldn't lose anything that way (but, backing up first is always a good idea).

Just Tried that (Good Idea), but no luck. I believe that the COMMAND file is only used when you execute the ZIP from recovery so It appears I am out of luck. The good news is that my Tablet is running great, just have no way to backup or restore an Image.
I may be suborn, but I believe there must be a way to get recovery working again. I do see that there is a recovery.img file on both my SDCARD and EMMS.
When I try and start recovery, I do get the Recovery Key Detected, just never goes into the recovery program.
This is an interesting problem ...

roebeet, Did not see your post until just now, I will reseach the NVFlash as I see there are a few threads on using it. I assume you can select what to flash.
Thank your

Tried the NVFLash and here is what I got

Help!!!!
BUt it still boots fine
Now on trying recovery Mode it says Booting Recovery Image after recovery key detected (So a little progress is made)

I am wondering if I need to get the specific recovery image for the recovery partition. I was just using the one that came with NVFlash. I downloaded the NVFlash_Gtablet and there are 11 image files so I do not know what Image file is for the Recovery Partition.
Am i on the right track yet???

JUST fixed this problem for myself, I'm gonna post another thread with a how-to of how I fixed this.

Recovery is image 9. There is a recovery image floating around here that can be used in place of image 9 and it will put clockwork back.

[GUIDE]NVFlash Procedure to Load ClockWorkMod (CWM)

Following is the NVFlash procedure for installing ClockWorkMod (CWM) for those
people who are having boot loop problems (or other problems) and need
to install CWM by flashing rather than by using /sdcard or a microSD card
via /SDCARD2. No apologies -- this is written so even the new folks can use it.!
1. You need to get a copy of ClockWorkMod v.8, which can best be done
by downloading through the following thread. Also, you might check the
thread for related info -- it's a good one:
http://forum.xda-developers.com/showthread.php?t=1010943
2. Once you have the CWM files, go to your NVFlash directory (or whatever
you call it) and make sure you have the right files in it.
-- Nvflash.exe and related files (nvflash_gtablet_2010110500.zip) from
the original NVFlash Recovery thread.
-- USB drivers (also from NVFlash Recovery thread. If you already are
flashing via APX you should have them installed.)
-- The file "nvflash_gtablet.bat" from the NVFlash Recovery thread.
-- The CWM .img file (next item will tell you how to get it.)
3. Next you will need to extract the CWM .img file from the .zip file you
downloaded. First, extract the files from the download -- you should get
a recovery folder and an update.zip. Now unzip the update.zip file and
you will get a file named recovery.img.
4. Rename the file "recovery.img" to "part9.img".
5. Now edit the file "nvflash_gtablet.bat to make the command line read:
"nvflash.exe" --bl bootloader.bin --download 9 part9.img
The command line above for the .bat file does require the quotes around
nvflash.exe!!!
Or you can simply leave the other .bat file alone and create a new
nvflash_cwm.bat file and put the cwm command line in it if you want to.
6. Boot your tablet into APX mode using power/volume - (you will have a black
screen). Connect the USB cable from your G-Tablet to your PC. If you check
the little USB/green check icon on the PC toolbar (bottom right corner of screen)
you see an APX connection listed.
7. Go to the NVFlash subdirectory on your PC and run the .bat file to load CWM.
8. When the flash is done, use the USB/Green Check icon to disconnect from
the PC and then disconnect from the G-Tablet.
9. Shut down and the boot the G-Tablet into Recovery Mode by pressing
Power/Volume + and hopefully you will see the word "Android" and then the
green CWM menu will appear."
Now you're ready to do whatever you need to do with CWM.
Hope this helps.

This suggest that NVflash tool is more versatile. Not only can you flash the stock ROM but also the recovery and perhaps other ROM's as well.

Thank you for the post. It worked wonderfully. It saved me from having to buy a sdMicro card that I would not need otherwise.

holzy99,
NVFlashing is most useful -- but it also is useful to have a microSD card handy.
In the Q&A forum you will find a similar post I did on how to install CWM using a
microSD card in a pinch. When you need it, you need it!!!

very nice!
just need some clarification..
where are we installing the NVFlash directory and APX drivers?
on the PC or on the Gtablet?

On your pc.

Help needed in NV Flash
Sticky thanks for putting such a detailed guide and appreciate that very much. I followed your guide and i am stuck at the NV Flash started. I believe that I had a confusion while editing the nvflash.bat. I edited the NV Flash.bat as following:
"nvflash.exe" --bct gtablet.bct --setbct --bl bootloader.bin --download 9 part9.img --create --go
@set /p batuserinput=Press enter to continue:
Please let me know if I an making a mistake here.

punjabigator,
You were very, very close. The command line needs to be \
exactly what was in the Procedure:
"nvflash.exe" --bl bootloader.bin --download 9 part9.img
Change it to that and try again.
Rev

Didnt work for me stops on
"nvflash.exe" --bl bootloader.bin --download 9 part9.img
Nvflash started
and thats it

Same here
NVFlash starts, but doesn't go anywhere. I am trying to get back to CWM after an NVFlash that has left me with arecovery kernel boot image message switching me away from CWM. Any advise?
Thank you for all you have done for everyone using these! It has been a lifesaver!

Power off
Press Power And Volume-
Start NvFlash

I am going to receive my gtablet this weekend and the first thing I was planning to do was install cyanogenmod. According to the guide on the cyanogenmod website (http://wiki.cyanogenmod.com/index.php?title=Viewsonic_G_Tablet:_Full_Update_Guide), they do not mention anything about nvflash. Is that really required. This is the first time I am modding. Thanks

still stuck in boot loop
Tried this .bat change, it did complete successfully but there were no changes.
Now I can turn it on and have SV birds/gtablet screen changing and shutting off at the end. I can use Nvflash but like I said, regular .bat or this modified didnt work.

anyone in the south Florida area , i cant get this to work right too many downloads g- tablet is driving krazy

Problems with NVFlash
Ok so I have CWM and BL 1.1 on my GTab. I would like to move to BL 1.2 so that I can install a 1.2 Honeycomb.
I also only have access to linux.
So I got the Linux NVFlash tool. I try to get into APX mode and that just boots me into the CWM recovery. NVFlash does not find my GTab.
lsusb shows:
Bus 004 Device 031: ID 0955:7100 NVidia Corp.
Then when I try ./nvflash_gtablet.sh I get:
Nvflash started
UnKnown device found
Done!
Nothing happens.
What am I missing? Has anybody found a good Linux how to?
Thanks
edit
Figured it out.
It is power and volume -

Yep same problem for me.
New gtab 2.1
Followed cyangen install instructions in the update guide and there was no mention of differences between 1.x and 2.x platforms. SO of course I put a 1.x CMW on my 2.1 platform. Cant boot into recovery. Can boot into the god aweful stock rom.
Followed the NVflash instructions. Installed drivers.
One interesting note is that after finding the apx device, pointing to the drivers, and completing the install (windows of course), there is no apx anything in my drivers lists.
Im in desperate need of getting CMW on this thing.
THanks for you help.

Go here http://viewsonic-gtablet-for-dummies.webs.com/nvflash.htm . Do the 1.2 branch (4349) Stock Rom 1.2 brach with CWM preinstalled. Follow the instructions. One you get back to stock 1.2 branch, go the Start Here page http://viewsonic-gtablet-for-dummies.webs.com/ and do code green.

Can you expound alot!!! What rom are you on, what were you doing, what do you mean by can't boot from any media, etc. Be as detailed as you can so we can assist you.

I think I might be missing something and I apologize if you feel like you are repeating yourselves but when you edit the .bat file what exactly do you put in the file? If someone could just paste into here what it looks like that would be really helpful.
Thanks for the help

Unbrick g2x Alternative method....(xp not needed :D) WORKS ON WIN 7

This is what worked for my phone....i'm not responsible from what happens to your phone your responsible for your own action...DO THIS AT YOUR OWN RISK! THIS METHOD doesn't require XP
OK so your phone is bricked because of the update by lg and your are stuck at the s/w screen...and The other method of flashing the KDZ file and program keeps freezing and not working even on XP ...if you haven't tried that method first you should its much easier and faster if you have and it's FAILED then hopefully this will help.
EASIEST FIX!!! This is for KDZ just encase you havn't tired this first my method is below....
Credit to bullseye69....THIS WORKs FOR WIN 7 ....so i guess you could try vista...but i'm not sure.
http://forum.xda-developers.com/showthread.php?t=1183168
READ FIRST!!!!
FOR BULLSeye69 his phone was working SO he used DIAG MODE BUTTT
IF your at s/w screen OR HAVE NO BASEBAND and NO BATTERY and NO IMEI...DO everything the same EXCEPT!!!! change DIAG to CS_emergency AND IT WILL WORK...give it a couple tries ....if it doesn't work first 2 - 3 times it's ok go to task manager and Right CLICK on the LGUPDATE tool in the process list and change set priority to HIGH and it should go through. HOPEFULLY THIS FIXS IT GOOD LUCK G2x owners
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
IF the Above method Does not work after like a million tries LOL there one more at the bottom ...Scroll down
~

OTHER METHOD : ONLY use this IF KDZ methods did not WORK (again at ur own risk)
hopefully this method will help you....(tried to be noob friendly as possible) READ THE WHOLE AT Thing LEAST ONCE
(PS download all those files they tell you to download because you will need them and i take no credit for those programs and files just this method on how i used them)
OK my phone condition was (2.2) s/w update screen....and was able to boot into cwm(clockwork recovery but not stock) using the ONE CLICK RECOVERY (internal sd flash)
So on stock 2.2 stuck on s/w update screen
my first mission is to just get past the s/w screen since i tried flashing a nandroid backup which i downloaded and it didn't work. (ps download the nandroid file "LG-P999-V10f.rar" credit to the dude who uploaded it )
Extract it using winrar or whatever program.
Now once you have the nandroid file you should see one md5 file and 6 .img files like recovery, system, etc....
so we gotta flash each one at a time....pain in the *** but if it works you'll thank me
OK so i was thinking like this kdz flash thing didn't work for me so i want to do everything manually ...alot of work but i have a 500$ paper weight...tough to figure the language but give it a little time.
LIST OF WHAT YOU NEED
One click recovery
Drivers installed
Nandroid file
so (assuming you have all the programs downloaded and installed) take all the img files (not the md5 one) and paste them into the nvflash folder of
the one click recovery folder.
Now open command prompt (type in search cmd)
we will used Command prompt next take battery out and press and hold up AND down volume buttons together and plug in your phone
(Apx driver should be recongized if drivers are installed)
Command i found to use (again credit to who made the command)
normally command promt (cmd) it starts with "c:\user\user"
so change this to where you saved the oneclick file...(easier to save the one click and other file right on c drive not into other folders)
For example my file is save in C:\oneclick\nvflash
SO this means i saved the file in c drive, and i need acess to "nvflash" folder inside "one click" since the nvflash program is in that
folder...
So change the location to where you want to access type in
cd C:\oneclick\nvflash (this is my file location obviously)
command language
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 8 .android_secure.img
NOW UNDERSTAND THE LINE SO YOU CAN FIGURED IT OUT EASIER...i'll try to be noob friendly as possible
"nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --"
this line for you noobs out there (not trying to insult lol) is just copy paste ok BUT
the second part ""download 8 .android_secure.img""" download is standard so that's also copy that
but SEE the 8 that number is the partion number ...bascially divsions on a harddrive so the 6 img (image)
file goes in their own number...so i'll post where .img file went in which partition but you may have to play
with the number to find ur phone's particular number...i'll explain futher
SO partiton number 8 is where my android_secure.img flashed and went throught without an error
so now i'll post the command for each img file that worked for me hopefully works for your G2x
(REMEMBER!!! after each command goes through the phone will turn on to the S/w screen , Once it says SUCCESSFUL (on CMD) unplug and plug back in hold the 2 volume keys)
for the android secure img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 8 .android_secure.img
for the cache img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 9 cache.img
for the boot img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 11 boot.img
for the system img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 7 system.img
for the data img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 15 data.img
~**NOTE IT IS BROUGHT TO MY ATTENTION THAT its possible that by COPYING PASTING ADDITIONAL SPACES MAY have been enter into the line so double check there are no extra spacing because then the command line becomes useless and doesn't work~****
NOW if they show an error like NV 120000 000 or something like partition error... then the NUmbers of your partition of where
these files go are different on your phone So it's not the END OF THE WORLD just play around with the numbers they are usually
very close so if number 15 doesn't work for the data.img then try 13, 14 or 16 they should be just one or two numbers away from
mine. (sometimes if says nvflash started and nothing happens you just have to unplug and plug again holding the 2 buttons)
Trial and error is how i obtained these numbers.
once all these files are sucessful goes through do a test but putting in your battery and going into recovery or just try booting (you not suppose to be plugged in for this)
it normally if it shows LG logo and goes to another LG logo with a LOading bar at the bottom wait for it may reboot,
IF it doesn't reboot it's OK because (after the normal boot) the S/w screen doesn't show up you have SUCCESS because the nandroid file SHOULD
work.
(IF your S/w screen has not gone away YOU Might HAVE TO wipe everything using CWM(Recovery holding power and down) and i mean everything format everything for every option that
(you get in CWM (recovery) go through what i did ....but THAT's only if you cannot get rid of the s/w screen )
(and then try again from the begining REMEMBER WIPING = LOSS in BASEBAND aka calling connectivity so through CWM make a backup of your file and save to your computer you may need later)
OK so we don't need cmd (command pompt) anymore you got your s/w screen to go away.
Now use NVflash and click the "one click recovery" button
(plug in the phone again (no battery) holding 2 volume buttons) and flash CWM to INTERNAL SD (not external)
IT's the first Button on the left (you should see 3 buttons to click on )
once it goes successful you can close the window and unplug.
pop in battery reboot holding POWER AND DOWN VOLUME KEY ...KEEP HOLDING till you see ANDROID RECOVERY (has like pictures of apps falling or something)
then the menu should pop open go to the mounts and storage and then all the way at the bottom (use volume keys to go up and down) mount usb storage option
and (make sure usb plugged in now) hit power button to open STAYY!! in that menu to acess the Storage on the phone...don't exit or hit unmount
nothing will happen if you do by accient exit...just it's easier to explain this way lol
now you should see on the PC (in my computer or automatically open the drive storage for your phone) in there you should see your folders and one of them is clockworkmod
in that there should a folder called "backup" if not make one, all small letters "backup" in there copy the whole LG-p999-v10f file you extracted into the backup folder.
now on the phone (once it transfered the file) hit unmount or hit go back using power button and go back to the first menu
above the mounts and storage option there should be the "backup and restore" option ...open that and hit the restore option and
you should see the LG-p999-v10 file there and hit power on that and go down to yes option and hit open and let it run should take roughly 5 mins.
let it go till it comes to the menu again... now hit reboot system...phone should turn off...if it doesn't turn on within 2-3 mins you can turn it on
your self and android should up and running YAY!!!!
(This is for only people who did a full format when they couldn't get rid of the S/W screen)
Now i have had some battery/signal issues....Thats because i did the full wipe of everything some people may or may not have this same problem hopefully someone can post a radio file zip or something ....cyogenmod is another option but i haven't tested it yet
will post result of the battery issue later
EDIT:I have put cyanogen mod (credit to cyanogen mod guy lol) on and seemed to fix the battery reading issue.
EDIT:
IF NO BASEBAND AND NO BATTERY TRY METHOD 1 again at top of the page
KDZ in CS_emergency mode ...and if on windows 7 setup the KDz as in the link above (bulleye69) then proceed to flashing it in CS_emergency mode
HOPEFULLY THIS HELPS ALL THE REST G2x semi-bricked owners....DON"T FORGET TO HIT THE THANKS BUTTON!!!!!

we will used Command prompt next take battery out and press and hold up AND down volume buttons together and plug in your phone
(Apx driver should be recongized if drivers are installed)
Command i found to use (again credit to who made the command)
normally command promt (cmd) it starts with "c:\user\user"
so change this to where you saved the oneclick file...(easier to save the one click and other file right on c drive not into other folders)
For example my file is save in C:\oneclick\nvflash
SO this means i saved the file in c drive, and i need acess to "nvflash" folder inside "one click" since the nvflash program is in that
folder...
So change the location to where you want to access type in
cd C:\oneclick\nvflash (this is my file location obviously)
command language
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 8 .android_secure.img
NOW UNDERSTAND THE LINE SO YOU CAN FIGURED IT OUT EASIER...i'll try to be noob friendly as possible
"nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --"
this line for you noobs out there (not trying to insult lol) is just copy paste ok BUT
the second part ""download 8 .android_secure.img""" download is standard so that's also copy that
but SEE the 8 that number is the partion number ...bascially divsions on a harddrive so the 6 img (image)
file goes in their own number...so i'll post where .img file went in which partition but you may have to play
with the number to find ur phone's particular number...i'll explain futher
SO partiton number 8 is where my android_secure.img flashed and went throught without an error
so now i'll post the command for each img file that worked for me hopefully works for your G2x
(REMEMBER!!! after each command goes through the phone will turn on to the S/w screen , Once it says SUCCESSFUL (on CMD) unplug and plug back in hold the 2 volume keys)
for the android secure img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 8 .android_secure.img
for the cache img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 9 cache.img
for the boot img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 11 boot.img
for the system img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 7 system.img
for the data img file:
nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 15 data.img
NOW if they show an error like NV 120000 000 or something like partition error... then the NUmbers of your partition of where
these files go are different on your phone So it's not the END OF THE WORLD just play around with the numbers they are usually
very close so if number 15 doesn't work for the data.img then try 13, 14 or 16 they should be just one or two numbers away from
mine. (sometimes if says nvflash started and nothing happens you just have to unplug and plug again holding the 2 buttons)
Trial and error is how i obtained these numbers.
once all these files are sucessful goes through do a test but putting in your battery and going into recovery or just try booting (you not suppose to be plugged in for this)
it normally if it shows LG logo and goes to another LG logo with a LOading bar at the bottom wait for it may reboot,
IF it doesn't reboot it's OK because (after the normal boot) the S/w screen doesn't show up you have SUCCESS because the nandroid file SHOULD
work.
(IF your S/w screen has not gone away YOU Might HAVE TO wipe everything using CWM(Recovery holding power and down) and i mean everything format everything for every option that
(you get in CWM (recovery) go through what i did ....but THAT's only if you cannot get rid of the s/w screen )
(and then try again from the begining REMEMBER WIPING = LOSS in BASEBAND aka calling connectivity so through CWM make a backup of your file and save to your computer you may need later)
OK so we don't need cmd (command pompt) anymore you got your s/w screen to go away.
Now use NVflash and click the "one click recovery" button
(plug in the phone again (no battery) holding 2 volume buttons) and flash CWM to INTERNAL SD (not external)
IT's the first Button on the left (you should see 3 buttons to click on )
once it goes successful you can close the window and unplug.
pop in battery reboot holding POWER AND DOWN VOLUME KEY ...KEEP HOLDING till you see ANDROID RECOVERY (has like pictures of apps falling or something)
then the menu should pop open go to the mounts and storage and then all the way at the bottom (use volume keys to go up and down) mount usb storage option
and (make sure usb plugged in now) hit power button to open STAYY!! in that menu to acess the Storage on the phone...don't exit or hit unmount
nothing will happen if you do by accient exit...just it's easier to explain this way lol
now you should see on the PC (in my computer or automatically open the drive storage for your phone) in there you should see your folders and one of them is clockworkmod
in that there should a folder called "backup" if not make one, all small letters "backup" in there copy the whole LG-p999-v10f file you extracted into the backup folder.
now on the phone (once it transfered the file) hit unmount or hit go back using power button and go back to the first menu
above the mounts and storage option there should be the "backup and restore" option ...open that and hit the restore option and
you should see the LG-p999-v10 file there and hit power on that and go down to yes option and hit open and let it run should take roughly 5 mins.
let it go till it comes to the menu again... now hit reboot system...phone should turn off...if it doesn't turn on within 2-3 mins you can turn it on
your self and android should up and running YAY!!!!
Now i have had some battery/signal issues....Thats because i did the full wipe of everything some people may or may not have this same problem hopefully someone can post a radio file zip or something ....cyogenmod is another option but i haven't tested it yet
will post result of the battery issue later
EDIT:I have put cyanogen mod (credit to cyanogen mod guy lol) on and seemed to fix the battery reading issue.
EDIT:
IF NO BASEBAND AND NO BATTERY TRY METHOD 1 again at top of the page
HOPEFULLY THIS HELPS ALL THE REST G2x semi-bricked owners....

I tried the command method cause KDZ keep force closing halfway and after that i flashed clockworkmod. When i restarted it still has the stock recovery, i got rid of the s/w but the problem now is that it gets stuck on lg logo with blue line and the menu buttons light up. I tried going into apx mode and s/w but the phone doesn't, it boots to the lg logo and the the blue lines.
Is there's any way to fix this?

Check the rom for recovery thread in Dev section, it will nvflash your phone to 2.3.3 gb rom. It will basically fix any brick and is our saving grace, huge props to iluha for creating it!

ok so you got passed the S/w screen at boot from my understanding and assuming that you manually flashed each file into it's partition...so now you used NVflash to flash and get clockworkmod recovery ? ok what happens when you pressed and held both the power and volume down what do see rather?

Ummm when does it say this exactly? like when manually flashing?

What did I do wrong? I tried the kdz method but it never worked after many, many, tries. My phone was stuck on the S/W Upgrade screen so I have to use the 2nd method.
I pressed the volume up/down buttons and put the usb cable in, waited for the driver to load (NVIDIA USB Boot-recovery driver for Mobile devices), let go of the two buttons, and I ran the first line "nvflash --bct 1108_Hynix_512MB_H8TBR00U0MLR0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin--" (without the quotes) and the cmd window stuck at "Nvflash started" but didn't budge and the S/W Upgrade screen didn't appear so I pulled out the USB cable and in the command window it stated "uid read failed"
Here's the cmd window info:
C:\Users\Toshiba M4001050\Desktop\WIND and T-Mobile LG Optimus 2X (T-Mobile G2X)

Now it doesn't boot at all, no S/W Upgrade appears, nada. *Update I got the S/W Upgrade screen back after reinstalling CWM.

Ummmm usually the if it says that it started and nothing happens you just do it again (unplug it & close program (battery is not in) press up/down volume buttons plug it in ..then thingy pops up as verified let go...and open program and try) now I couldn't help but notice your file name...but just make sure your phone is LG G2x not LG optimus 2x.... right?

Restoring the G2x to stock GB through nvflash

Since I've not seen this done here, and lately I had to do some research on how to pull this off I'll post it here for everyone's benefit.
I had an issue, where the phone would only boot to the recovery. Any recovery that I flashed with nvflash... and even when I flashed a perfectly good ROM image from ClockWorkRecovery, it would still boot into the recovery.
First of all, this will reformat the phone's internal storage, so get your precious data off the phone or make backups.
This method is utilizing nvflash program, which is available on both windows and Linux, to get your phone into the special mode where nvflash can talk to your phone you need to:
- have APX USB drivers installed if you are on windows
- disconnect your G2x from everything, and remove the battery (don't put it back)
- holding both Vol+ anf Vol- buttons, plug in the USB cable connected to your computer (where you have nvflash and the required files)
You can search the web for "APX" "nvflash" to get some more perspective on these things.
I'm not going to explain how to make backups of the partitions with nvflash. Suffice to say that there is --help option in nvflash and look for "--read N filename"
What saved my chops (and allowed me to wipe the partitions and bring everything to stock) was:
1) The files from the first post in http://forum.xda-developers.com/showthread.php?t=1248644
2) you can use this to restore your phone to stock:
Code:
sudo ./nvflash --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct --setbct --bl fastboot.bin --configfile android_fastboot_emmc_full.cfg --create --go

Thanks anyway, but unfortunately this way doesn't update the baseband/RADIO..only returns the stock ROM with same existing baseband/RADIO..
I have searched a lot, but is there any way to update baseband/RADIO?
(have tried KDZ flashing and LG updater it doesn't work)
Thanks

Boot Loop (Stock Rom) NV Flash no Option

Hi there,
Tried the search a bit, but nothing really fits my problem.
To make it short:
TF 101 -> Stock 3.0.1 ROM
Downloaded Update @ Asus Website (to get 3.1 / 3.2)
Put on SD Card
Installation aborts (Android with yellow/black "!" Picture)
Since that only Boot Loops
Serial is B70, so NV Flash would not help, right?
Is there something I can do to get this wonderful device to work again?
Some background info:
Bought it off "used" from a marketplace. Told me he was on Revolver Rom before. But he unrooted and went back to stock (3.0.1 and Asus Recovery) to sell it. After I checked for software updates since the version was 3.0.1 (and i know that 3.2 is out)but the System told me "No Update Available", I wanted to manually update (Asus Site /SD Card). I made sure the version was the correct one (DE). After aborting installation I also tried the WW Version.
Thanks for any help!
adios

Some B70 are NVFlash compatible. Just try it, might work might not.

Thanks for the answer!
After installing the USB Driver and setting APX Mode I got this:
(sidenote: when I run the download.bat via explorer it closes instantly)
is there maybe another method that I´m missing?
Thanks a lot

If I am not mistaken, the rcm version 0x4 means you have SBK2, which can't be recovered with nvflash, this is what I got when I tried my new TF101.
this brings the question: What is the Stock Asus recovery useful for? can't it recover a stock rom from the sdcard?

Can you get back into recovery mode? i would suggest downloading another coy of the stock ROM, place it on your SD card name it WW_epad-user-8.6.5.19.zip (or whatever the name of the firmware version is, but I would recommend this version) and try to get bck into recovery again..worth a shot

Thanks for all posts!
Tried different Firmwares from Asus so far. 8.6.5.(21 & 13 ) DE and WW (just in case even US)
8.6.5.19 is missing on Asus Site
None of them worked. -> Short unpacking animation -> Android with "!" Sign
I put the device into Stock Recovery (Power + Vol Down)
Option 1:
Hit no Button -> Wipe User Data (when I chose this the TF101 stucks after "This could take a few minutes...")
or - Cold Start Device (changes nothing)
Option 2:
Hit Volume Up (within 5 Secs)
Booting Recovery Kernel Image
-> Android with Exclamation Mark Sign (even if no SD is inside)
The curious thing is. The Eee Pad will not stay off anymore. After holding the Power Button it just fires up again and stucks at Boot Logo.
I wonder why this all happens to a "non" root device with Stock ROM(´s)
Thanks to all you guys!

You are extracting the files after downloading correct?

What I get after downloading is a .zip (e.g. UpdateLauncher_US_epaduserV8_6_5_13)
After extracting with winrar 4.0 (x64) there is "Asus\Update\WW_epad-user-8.6.5.13 (.zip)"
put WW_epad-user-8.6.5.13 on root on MicroSD
(like on every tutorial found woth google)
(tested it also with Folder Structure (Asus\Update\ or Update\)
Nothing worked for me.
But I will try something using another extraction tool. good idea.
Thanks! -> downloading with another browser and using 7zip changed nothing
Edit: Someone got a link to 8.6.5.19 Firmware?
When I rename the Update into "EP101_SDUPDATE" the installation bar shows up and runs a while. but after a few seconds again Android with exclamation mark

Any news here? I have the exact same problem..
I bought my new TF101 (B70) a couple of months ago. Never rooted it nor istalled anything strange (just 100k+ downloaded apps from stock market). Last week it started crashing.. Got it boot looped but wiping data did the trick. Now it is boot looped again and wipe data doesn't work anymore ... any ideas?
