[Q] New O2X dead or super bricked ? - help

First of all I would like to welcome the entire XDA community.
I have searched all known forums for the rosolution of my problem with no luck.
I've bought a new P990. I have updated it with the LG update toll to the new official android version 2.3.4. After the update the phone worked ok for about an hour (just enough for me to remove all the stickers) after that it started crashing. I had to take out the battery after it froze and it started. There were still some issues with apps so I turned it off with the power switch.
Now the drama begins...
After I switched it off it went dead. I can't turn it on at all not even in recovery mode. It doesn't charge if connected (although I've checked the battery is good). After connected to the PC by original USB cable it is not seen at all.
The phone is only seen in APX mode so after finding the http://forum.xda-developers.com/showthread.php?t=1007825 I was sure I can bring it back to life. But I was wrong
It went successfuly through the whole nv flashing process a few times but the phone would still not turn on at all.
Now each time i run the flash.bat I get the following error:
C:\o2x>.\nvflash.exe --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_

I have run the nvflash on 4 different computers with different OS on different USB cables. Is there anything else I can try? Some way to fix the partition table or something?
Or maybe my O2X is physically damaged - in that case will LG honor my warranty?
I have to go abroad within 2 days so any help would be most appreciated.

Bartek

Sounds like hw. Contact LG

Send to the warranty and wait for repair

Hi bpraniuk,
it's possible that this is a hardware failure, but you should try this method:
|Download Smartflash P990:
Here
|Download Drivers:
Here
|Download Good stock ROM:
Here
I think, the good rom is:
Here
>>>>How to do<<<<
1)Install drivers
|Turn device off, remove battery, plug device in while holding volume down - you should see a software update message on screen and the COM port should be filled automatically in the flash application below after installing the drivers if required.
2)Launch SmartFlash P990
3)Unzip the zip rom
4)Select the 'ROM Copy D/L' tab
5)Ensure 'Normal Mode' is selected
6)Ensure 'Erase CAL' is NOT selected
7)Click the browse button next to 'CP Bin:' and select the .FLS file
8)Click the browse button next to 'AP Bin:' and select the .BIN file
9)Choose COM
10) Start!!
When it's done return battery and power on your phone and redo the update
If the Phone crash again go to LG SAV -_-'
Hoping to have you helped
Bye

It certainly looks like hardware failure, try to return it with warranty before you do anything else.

may be your NV file was damaged try another sources

The Smartflash won't work because my o2x is not recognized by it. The binaries for nvflash are good I have downloaded it on several locations and checked the MD5.
I guess I'll try to return it to warranty I just hope they will honor it.

Bricked Optimus2X

Hello, i think my Optimus 2x is bricked. I flashed a wrong ROM and it would "freeze" at the LG logo. So I followed a guide that said would flash the phone to stock with NVflash. Anyway the guide said that I should go back to EXT3 FIRST before flashing but I forgot and now the phone won't even boot. Nothing happens when trying to turn it on. However my PC still sees APX/Nvidia recovery whatever when i plug it in.
Help.

Try this: http://forum.xda-developers.com/showthread.php?t=1229407
Also if nvflash doesn't work, try smartflash!

There is numerous threads with title brick, bricked and etc. Little search would be nice...

It doesn't work! The phone is stuck in APX mode! Doesn't matter what I do, if i plug it Windows says APX. There has to be a way! But the phone doesn't react to any buttons, whatever I hold, or do, it's still in APX mode and dead.

install lg drivers and flash kdz firmware and then root the phone!

on the first post, i had the same problem a week ago. what fixed my phone was flash stock ROM using smartflash, with the .fls and .bin file. its just like newly bought phone after the flash. hope it helps!

Thing is, I ran xda forum end to end looking for people with same trouble as I and I could not find any help. It's like a loop! LOL
If nvflash doesn't work use Smartflash, and vice versa.... LOL :frustrated:
Anyway, I'll keep looking.

Unfortunately SmartFlashTool doesn't work since the phone is running in APX and doesn't create port connection that SFT software can recognize.

Try to nvflash whole rom not just recovery. Ie pauls v10b. I hope it will work for you.

I tried both!
When I do the whole rom procedure it gives an error message, but since the cmd window closes right away i can't copy (or i am not aware of a way to retrieve the text....).
Supposedly after NVFlashing the whole ROM I should unplug the cable, install the battery and boot the phone.
At this point the phone doesn't boot, or at least nothing is showing on the screen.
Volume down+ power also doesn't work so I cannot do to CMW.
Do I need to send it to LG?
Thanks for your help anyways!

Actually I managed to keep the CMD window open and this is what I got:

Can you enter fastboot now or still stuck in apx? Just in case: Turn off the phone. Remove battery and
hold it removed for few secs. Put it back and press and hold vol - and power button. Keep it pressed and then try smartflash.

Still stuck in APX.

Thanks For Helping out!

Thats strange. Try to nvflash again without sim and sd card, different cable, different usb port (prefere those which are directly on motherboard on the back of your pc). Just a bunch of ideas.

But afterwards, it booted LG logo and sound and nothing else. I waited 20 minutes for something to happen until I removed the baterry and turned on again. and LG Logo only....
Then, I tried to battery off and volume down+data cable and i could smartflash. as result it booted once, No LG logo with blue halo but sound played, and again nothing happened for another half hour until i turned off and NVFLashed again and bricked the phone again.
So, now, back to step 1, My phone is stuck in APX and I don't think NVFlash will solve even if it works after 30 tries.

Maybe I have the solution:
Just download the right version of stock gingerbread, check this link:
http://www.todomovillg.es/elforodehomero/index.php?topic=317.0
With this .kdz file, you have to use the KDZ Updater and the LG driver.
Download the latest LG driver here and intall it right after: http://www.lg.com/ca_en/support/mc-support/mobile-phone-support.jsp
UNPLUG your phone before installing this driver.
And the KDZ Updater here: http://forum.xda-developers.com/attachment.php?attachmentid=420545&d=1287222698
When that's done, extract the KDZ Updater folder on your desktop.
1. Open it and install the msxml.msi file.
2. After that, run the KDZ_FW_UPD.exe
3. In that software, you will choose Type: 3GQCT and the PhoneMode: DIAG
4. Choose your recently downloaded .kdz file but DON'T LAUNCH SOFTWARE UPDATE yet.
5. PowerOff your phone and pull out the battery.
6. Hold Volume Down and plug in it to your computer with your USB cable.
7. Your phone must be in S/W UPGRADE Please wait while upgrading...
8. When that's done, just push the Launch Software Update button.
9. WAIT until it reboot and put your battery in.
10. When kdz updater finish, unplug your phone and Enjoy. :good:
Hope that help.

Do not use Smartflash, bro.
Use nvflash in this post, I used to have a half-brick O2X but this post saved me
http://www.modaco.com/topic/335474-25-mar-nvflash-stock-rom-release-v10b-dated-1300166062-15032011/
Good luck! Yuo will need it.

Try to use stefan's ics nvflash version, i think his thread is on page 3/4, then boot it up, if you're planning to use cm10 with the new bootloader use aio tool, or you can download the stock gb/froyo from modaco then nvflash it

Power it off, remove battery, hold vol- and insert USB cable.
If it shows something about SW Update on the screen, then just smartflash a stock ROM, then start again. Saves dicking around.

sw upgrade boot doesn't work either
Thanks for ur reply Rusty...!!
I tried SW upgrade boot also, it didn't work .. flashes lg logo and turns off... if i keep on holding vol - button, it blinks again and again.
I think i bricked my phone.. Internal sd-card /emmc,/cache)is not recognized/mounted.

It's pretty much impossible to brick it. NVFlash will fix it.
When you tried, was the phone plugged directly to the motherboard or through a hub/front ports? Direct is best.

Yes, i tried through serial port and tried with other port also, didn't enter S/W upgrade screen.. (Mine is Dell XP15 - win7 )
Have installed latest LG drivers and nvflash drivers are latest and showing up in device manager also..!!
Through nvflash it stucked - bad data or hangs for hours..!! (have tried changing data cable too)

Before giving up, borrow some time on a desktop computer, connect directly to a port on the motherboard, try again. Use a USB2 port.

Re- Use a USB2 port.
When i connect to usb3 ports, it detects APX device and 'NVIDIA USB Boot-recovery driver for Mobile devices' appears in device manager.:angel:
But when i try usb 2 port, it prompts as unkown device(usb device not recognized) -[ Lg drivers work with usb 3 ports] and not able to proceed further.
I have always used usb3 ports for rooting O2x and all- it went fine, should i still need to debug on usb2 unknown device issue ?

Nvflash worked..enters sw upgrade screen
Friends, nvflash works successfully and files sent successfully and phone enters S/W upgrade screen.
If i release usb cable, put the battery and power on with vol-down, it again enters into CWM and not S/W upgrade screen.
Need to know what are the next steps to do , also what are the files that i have to put in sdcard ?

addition to this.. adb also working..
Friends,.. now nvflash works and i am to do some basic ADB commands also..!! [Smartflash not working - due to phone not entering s/w upgrade]

Need your help - What are next steps i should do ? What are the files i need to download to make my O2x work? :fingers-crossed:

Well if you can ADB in recovery, I guess you should download a ROM, stick it on your SD card and flash it.
OR
Remove battery, hold vol down and plug in USB cable to get the S/W Update mode, then you can smartflash.

Waiting for bootloader to initializer
Hi vsnstarguy,
I have a situation like yours. My device is dead and nothing shows on screen. I've tried that methods, nvflash, smartflash but my device is realy dead and I got the same status like you:

Nothing happens after this!!!!
Hekp me!
I've opened a thread about this but nobody could help me yet!

Thing is, most people manage to get passed that point. If you've plugged directly into the motherboards USB ports, have you tried another computer?

@cl06 - nvflash and adb works..!!
@cl06 - Dude, is you phone p990 or p999 ? you seem to be trying with p999.
Nvflash p990 correctly, it will work.. (got this from Rusty thread)
or navigate it to your nvflash folder for p990 and try below command--
nvflash --bct E1108_Hynix_512MB_H8TBR00U0MLR-0DM_300MHz_final_emmc_x8.bct --bl fastboot.bin --download 14 cwm-int.img
In above nvflash command - after download for p999 it will be 5 for p990 it will be 14.
For some intermittent issues, i changed usb cable and now nvflash works but im still in bootloop for which our friends here will help us

Possible Brick NVFLASH help needed

Hello –
Thanks in advance for reading and any help you can provide..
my phone is currently dead ... I’ve managed searched xda forums/internet and downloaded various NV Flash and read a bunch of threads and guides but still need some help.
I can hold vol up and down and plug the phone in to my computer (win 7)
Windows loads the APX device (ive checked device manager and the drivers are successfully installed.
(USB Controllers reads - NVIDIA USB Boot - recovery driver for mobile devices)
Driver version 1.0.1.0
NV Flash starts and the phone changes from a blank screen to “S/W Upgrade please wait while upgrading…”
but I’m getting an error part way through the nvflash sending the system img.. see below
ive tried a couple of different system images / nvflash guides and im still struggling
sending file: 1-system.img

seems like repeating many times is good for you. its failed again but this time got a lot further.
going to keep trying.

input the battery after start is OK.

my friend,
have you tried the AIOT...link in my signature (I have used the V5 version many times...dont know about the v5.5)...read the thread and you will have more info
but, there are tools and ROMs which are based on the NVflash method....progmaq's NVflash and unbrick tool, Homero's NVflash, Stefan's NVflash ROM....
LG O2X is almost unbrickable....so try it

Hi!
It seems like your usb ports dont like your phone. I have the same problem. Every time I try to flash full nvflash rom or flash stock rom or basbeband with smartflash it keeps failing. Nvflash showes the same error which you have and smartflash always write time out errors. I dont know why is this keep happening. The only solution for me is using usb3 ports. Strange, isn't it?
So if you have usb3 port try that. If you dont have usb3 port download aio-toolkit from the development section and use it to repartitionate your phone then flash a custom rom. I think aoi-toolkit should work because it does not take too long, so the timeout error will not happen

Hi guys, thanks for the replies
I've tried the AOI toolkit that got me so far, before i used that i couldn't even get anything on the phone screen
I've resolved the issue now - but for those who come across this thread bitdomo was kinda correct with my phone and USB. heres the stuff i tried before it finally worked
tried every usb port on my laptop
the same port multiple times
using the LG cable which came with my phone and other usb cables -
it finally worked when i used a new cable which came with my nexus 4 in one of the USB port at the side of my laptop.
not sure what the problem was but i know some usb cables arent the same as others - and some can provide more power - why the cable which came with my phone didnt work i dont know.
Thanks

TF701T NvFlash Unbrick Solution(tested)

TF701T NvFlash Unbrick Solution(tested)
(continue of the threadhttps://forum.xda-developers.com/showthread.php?t=2655888)
Charge tab before unbricking.
Connect tab to PC.
If your tab not started already in APX mode, then run APX mode by pressing button combination Vol+ and Power.
Insall drivers from "usb_drivers" if needed.
If there is a problem with the installation of drivers, use Google to search- how to install unsigned drivers.
When device installed correctly run "tf701t_flash.bat".
If flash process interrupts with error like ...read\write error..., then probably EMMC memory chip is damaged and need to replace.
If flash process complete, then we ready to next step.
Prepare fat32 formatted microSD card.
Download from ASUS site update package.
https://www.asus.com/us/Tablets/The_New_ASUS_Transformer_PadTF701T/HelpDesk_BIOS/
It _MUST_ be Version V10.14.1.47, SKU(region)- of your choice.
The downloaded file will look like **_epaduser_10_14_1_47_UpdateLauncher.zip
There will be another archive inside that archive.
Extract it, and rename it to t4_sdupdate.zip
Put t4_sdupdate.zip in root of microSD card.
Insert microSD card in tab, then start tab in recovery mode by pressing Vol- and Power key combination.
Follow onscreen instructions to complete recovery process.
After all you tab must be restored to factory state JB Android.
Now you may update firmware version using OTA or sdcard.

What is this? A covert ad campaign for Mega? How about hosting the file somewhere that does not force you to download an app, open an account and all that cr***? I'd be really curious to see the code, but not like this.....

Where did you see the ad or need to register, or requirement of install the program for downloading?
Just checking in IE and FF.
I see a big red button- "download", no ads, and no requirements.
Ok, for those who have problems with mega.nz added a mirror for download.

TF701t - Hard Reset Fails ...
Dear Community,
I wanted to hard reset my TF701t to delete my data and give it to another one.
But now it stucks in "deleting data" ... that endures a minute then a dead android is on the screen.
When I want to reboot it, the hard reset comes again and want to delete everything, but the dead android is coming back :/
I can't go in Recovery Mode (Volume-down + Power)
Connection to APX works but, see pic below ...
I don't know what I could try anymore ...
Hope somebody have an idea.
Best greetings,

Link to the picture is broken, so we cannot see what result you got...
What's your situation: Bootloader unlocked? Custom recovery? I guess not since you get the dead Android?

link to screenshot ok.
as i can see- problems begin after trying access to EMMC chip.
"Taking backup of EKS"
unfortunately with 90% certainty i can say that the EMMC chip damaged.

In that state the EMMC chip can be tested with the special equipment like EasyJtag box.

Hello Mr Bin, registered an account just to say thank you...
You have no idea.. was helping a friend to update, but the guy who sold it(tf701) had bought it from different region and turned it to US, so we ended up hard bricking it.
Long story short, we hard bricked it.
Thank you for your hard work in making the fix, and a big THANK you for sharing it...
Perfect fix, its better than before because it got updated to .47 (we couldnt update, no OTA no manual, too old version for custom recoveries)
Again.. thanks :good::good:

Thanks.
But, after clicking to RCK, shows Android with blue procesing line and after few seconds android with open door and red triangle !. After few minutes bootloop....nothing more.
What can i doing again?

Wow! It's back!
Hi.
First of all: Thank you very much! I was sure my tablet was a goner... It is actually back. One tip I'd like to add: I had to try around a bit to get into APX mode. But essentially I just had to connect the tablet to my PC and then push "Volume up" and power at the same time - and ignore that the screen did not light up ...
Again: Thanks a lot!

Mr.Bin,
You have resurrected my TF701T! Thank you SOOOO MUCH! You are an actual genius! Thanks!

Help w installation
I have the same problems although i have not installed any custom OS but after few months of not using it didnt load up and ended in APX mode.
Tried this solution, installed the driver, started the .bat file and ended up here :

I would be very thankful for any information you could read from this. Just would like to know if i even have a chance of getting it back on.

So, I was running fine with CROMi-X KitKat, but wanted to upgrade to Marshmallow (to install sw not supported in KitKat), so decided to try KatKiss 6.0. It's been years since I've played with flashing ROMs, but I did a little reading to refresh my memory. Then I rebooted into recovery (ClockworkMod), backed everything up, then wiped everything, formatted /data, and tried flashing the KatKiss zip file. At that point, it just sat there forever at the ASUS logo screen:
I've tried several times to boot back into recovery by holding the Vol+ and Power buttons, but it either doesn't boot, or boots to the above screen. I've connected it to my Mac w/ the Android SDK Platform Tools, but adb doesn't see any device listed. [I've got an old Windows laptop (XP?)] I could use if it will do something the Mac can't.]
Any advice on how I can save this tablet?

This method can be apply to tft300t?

Hi! What a great thread! After lurking on this forum for many years, i've registered to expose my issue with an old tf701 that was given to me by a friend. He say me he installed esexplorer and deleted file to clean space. Next day he rebooted and never been able to boot system. Now tablet is in bootloop ending with blackscreen and backlight on. Im able to open in fastboot and talk with minimal adb and fastboot. RCK update ending with fallen robot, Wipe data/cache ending with fallen robot. APX mode also working and ive run mr.bin's Nvflash unbrick tool with this result:

Hello. These commands for nvflash make a backup and installation of the system.
REED
@cls
@nvflash.exe --blob blob.bin --bl bootloader.bin --read 9 recovery.img --read 11 boot.img --read 12 system.img
@pause
WRITE
@cls
@nvflash.exe --blob blob.bin --bl bootloader.bin --download 9 recovery.img --download 11 boot.img --download 12 system.img
@pause
Thanks mr.bin for a great tool

Important information who uses nvflash!
3 files (ABTxxxxxxxxxxxxxxxx.bin, EKS_xxxxxxxxxxxxxxxx.bin, PER_xxxxxxxxxxxxxxxx.bin, which are created after running nvflash, must be flashed again. Otherwise, it will be impossible to unlock the tablet again and the serial number will be lost. Save in a safe place and then rename the files to EKS, ABT, PER.
To do this, create a second file with the bat extension. In a text editor, type these lines
Code:
nvflash --wait --blob blob.bin --bl bootloader.bin --download 7 ABT --download 21 EKS --download 18 PER --go
If these files are saved on the unlocked tablet, then after their firmware unlocking will be restored.
Also, using nvflash, you can resize partitions, flash a bootloader with file system markup, recovery.

There is no way to load an unlocked bootloader in this process ??
