[Q] TWRP wont flash rom? - LG Optimus 2x

Im very new to custom ROMS so forgive my ignorance.
I used the All-in-one toolkit to flash the new ICS bootloader and TWRP recovery image onto my phone.
If i'm not mistaken, i believe having the TWRP recovery means my phone is rooted.
When i flash a custom rom ( CM10.1 - tonyp) from my external SD-card the console on TWRP reads
Checking for MD5 file
Skipping MD5 Check: no MD5 file found
Updating partition details...
Click to expand...
Click to collapse
And towards the bottom of the TWRP recover it says successful.
However when i click Reboot System, TWRP then says "No OS installed"
What am I doing wrong?

hey guys, so I've got it working.
The problem was that I had flashed the new bootloader because i had assumed that a CM 10.1 rom based off of JellyBean would require the new B.L
Put the old bootloader in and it works!
Anyways thanks guys

i cant flash CWM on recently updated phone (LG ICS V30A)

hello,
i recently updated to the official ICS for o2x, and now i wanted to flash a custom ROM again.
so i tried with ROM manager to flash CWM, but my device is not listed above in rom manager.
i tried to install manually with nvflash, and this also didnt work, every time i try to flash cwm, it gives me this error:
downloading bootloader -- load address: 0x108000 entry point: 0x108000
sending file: fastboot.bin
/ 1024992/1024992 bytes sent
fastboot.bin sent successfully
waiting for bootloader to initialize
bootloader downloaded successfully
failed executing command 14 NvError 0x120000
command failure: partition download failed
anybody has any idea how to fix this, and flash CWM?
additional info: im on the new ics layout, my bootloader is unlocked, i have root, USB debugging was on, and i have the correct APX drivers.
Use this tool to flash things ... It has correct recoveries included for old and new bootloader .... http://forum.xda-developers.com/showthread.php?t=2020737

Then you must be doing something wrong.... May be flashing something meant for old bootloader to the new bootloader ..... Bootloop at what point ??? Are you able to enter recovery ??? AIO Toolkit is a proven solution working for all P990's.... Also, which Custom ROM do you want to flash and for which bootloader, old or new?????

it gets me in the bootloop after changing the recovery image, and then booting in the recovery gets me in a bootloop. (bootloop only happens with toolkit) i tried the latest version available, and with nvflash, i tried it with cwm 5.0.2.0. im not flashing a rom cuz i cant flash cwm yet

Then you might be choosing the recovery for old (GB) bootloader ... Since you are on new bootloader, you will have to choose recovery for ICS bootloader... Use recoveries given within the toolkit itself....

[Q] broken recovery on stock 4.2.2

Dear all,
I've a tf701 with stock 4.2.2 build JDQ39.WW_epad-10.14.1.2820130827
I've been able to root it through adb/fastboot.
I tried to use the same way to flash the recovery and adb says "ok"
Problem is that when I launch RCK on fastboot; it starts normaly, not in recovery.
I'd tried to update the tf701 but update process tried to restart in recovery and it is the same thing I describe above.
I tried also rom manager to flash the recovery but the device is not superted yet.
If somebody could help me providing a recovery.img that work with JDQ39.WW_epad-10.14.1.2820130827 it would be great
Thanks in advance for tips and comments

DO NOT USE ROM MANAGER! Fastest way to brick a transformer. Lucky you didn't.
Which recovery are you trying to flash?
Have you tried upgrading to 4.3 from Asus?

I tried to flash CWM recovery, on adb it was a file called recovery.img but to my understanding it works with the asus stock 4.3 not the 4.2.2
OTA asus update dosn't work
I tried to update placing a SD card with the asus update, got a notification that my device will be updated but.... nothing the device restart (guess try to boot on recovery so fails and start normaly
still stuck there
Any ideas?

No you must go to JB 4.3 10.26.1.18 first.

Easier if you install the stock 4.2.2 recovery from that url and then put the zip inside the asus firmware zip in the root of internal or micro sd and reboot. It should update to 4.2.2 that way. I don't think you can flash asus stock roms from CWM yet.
Ok,
I flashed the recovery found at this url: http://droidbasement.com/asus/tf701t/stock/
It won't start, I boot android normaly instead of the recovery I think it is a recovery only for 4.3
The only recovery I've found for 4.2.2 id CWM

Some news; flashed several times the recovey, adb flash without errors but trying to update asus update (WW_10_26_1_18_SDupdate.zip or WW_epaduser_10_26_1_18_UpdateLauncher.zip) my tf701t restart and that's it, no do anything more and I still stuck to 4.2.2 JDQ39.WW_epad-10.14.1.28
I've contacted asus; I hope they will be able to help me to restore the recovery.
just to be sure, it is not possible to flash the stock firmware from adb console?

You have to unzip the ....UpdateLauncher.zip once which will give you a .....user.zip. That's the file you need to flash.
Yes I know, I've do that, it has detect a firmware and starts the update process but only restart the tab.
After that, when I plug again the SD card with user.zip nothing...
Firmware is no longer detected on SD card.
Still with recovery issue that's why I wonder if it is possible to flash stock ROM through adb.

Not in ADB - Android can't be running when you flash the system partition but you can flash the system blob in fastboot.

Ok thanks for the info.
I no response from asus support concerning a way to restore the 4.2.2 recovery I'll do that.
Just to be sure, I erease ell partitions (system, recovery, user data, boot, misc, cache and only flashing system (blob file) will re write every partitions?

.
The system blob contains everything: kernel, recovery and system files. It does not re-write user data naturally, and I don't think you have to wipe that partition. Doesn't sound as if your trouble is related to user data.... So you should erase system, boot and recovery. I would also erase misc and cache - can't hurt...

Ok, thank you for your interest.
I confirm that with recovery CWM for stock 4.2.2 it is not possible to flash the firmware provided by Droidbasement.
got the error message:
assert failed getprop ("ro.product.device") == "tf701t" || getprop ("ro.build.product") "tf701t"

I tried to go back to stock recovery but the one provided on droidbasement doesn't work; when "RCK" selected on fastboot mode, it says "booting recovery kernel" and restart the tab; that's all.
Same thing when tried to update asus stock firmware placing the update on SD card it's only reboot the tab.
To my understanding the stock recovery image provided by droidbasement works only with 4.3 stock not 4.2.2 stock.
So I'm able to flash a recovery CWM for 4.2.2 but can do nothing with it and not able to go back to a workable stock recovery
When I try to flash the stock recovery on droidbasement, it just restart the tab, still stuck at this step since 1 week.
I'm waiting a response from asus support I asked them a recovery image for stock 4.2.2
If they are not able to help me, I'll considere to flash the blob in fastboot.
Obviously if someone get tips to help me I'll reconsidere my plans

Yes, you are right, asus support just tell me a kind of **** you...
As asus blob file get everything including the recovery, I've downloaded the 4.2.2 update from asus and unpack the blob to get the recovery.img
unpacking blob file I've got:
blob.BC1
blob.BCT
blob.EBT
blob.PT
Anybody knows where is the recovery file and how can I do to make it flashable?
EDIT: I guess recovery is not in the blob file but in a recovery folder containing recovery-from-boot.p

[Q] stuck in TWRP recovery with empty phone

hi i was trying to root a new o4x, and after everything went right. i unlocked my bootloader by going into bootloader mode and putting "fastboot oem unlock" command, and then chose "unlock it" it said my bootloader is unlocked.
after that i installed cwm touch latest .4.5 ver recovery, and booted in v20a rom, copied vanir rom into my internal sdcard and booted into cwm recovery and tried to flash vanir 4.4.2 rom into it,
after flashing vanir rom, it booted perfectly, but when i connected it to pc, it didn't show my files on internal sdcard which i coppied on it in v20a, i mean there was no vanir rom zip into my internal sdcard, but when i go into recovery and see in "install zip" n go to internal sdcard, it shows vanir rom zip in my internal sdcard.
i thought it's a problem of recovery, so i installed TWRP recovery, i wiped everything including system, and then tried to flash vanir again, and now it's not flashing vanir or any other roms, it says zip successfully installed in recovery, but no rom boot up,
whichever thing i change in TWRP it reset it after rebooting into recovery,
i think TWRP is not able to write anything into system or other drives,
now i'm stuck, i don't know what to do here, i can't flash anything, and my phone is already empty
please help me,

Flash back to Jelly bean just to ensure that all is okay with your phone and start the process of CWM and installing custom rom again.
There is some tut in General section going back to stock via offical LG Flash tool.
Good Luck.

Cannot install original firmware

Hello all,
Since my TF701T returned from RMA (touch screen issues), it has drained the battery like hell.
So I decided to flash original firmware again (done that before sending it), only to find out it now failed with this error:
Verifying update package...
E:failed to open /sdcard/T4_SDUPDATE.zip (No such file or directory)
So I renamed the zip to that file, but it didn't help.
This package is for "K00C" devices; this is a "tf701t"
In custom recovery log, one can find this:
ro.build.product=tf701t
ro.product.device=tf701t
Installed CWM, then flashed 2 custom ROMs (CROMbi KK and last AOKP), either system is stuck on boot or systemui fails permanently preventing using the tablet.
Then I flashed the original firmware with CWM instead of stock recovery, system stuck on boot-loop, except with 11.4.1.17, boot up but systemui fails again.
It's like the tablet Asus sent me back is not really a TF701T ?
Any help would be highly appreciated as the tablet is unusable at the moment, only boot-loader and stock/custom recovery are accessible.
Can you provide a logcat of the boot process from an adb connection please. Also the recovery.log from cwm (it's in /tmp/recovery.log so adb pull /tmp/recovery.log recovery.log)
It sounds like your system partition is not getting setup correctly or /data is corrupted somehow.
Also for stock you have to flash the zip inside the zip - you did do that right?
Let me get this straight:
You are on the 11.4.1.17 bootloader? That would mean you had the latest stock 4.4.2 firmware installed right?
The T4_SDUPDATE.zip is WW JB 4.3 firmware, is it not? You tried to flash that in stock recovery?
I read about one user who tried to downgrade from 4.4.2 to 4.3 yesterday and that also failed.
Another user contacted Asus support and they told him a downgrade is not possible from 4.4.2. No idea if that is true. The Asus reps are not always well informed....

Thanks for replying. Turns out I made a series of misleading mistake
First: custom recovery was installed, so it would not install an original firmware (device identifier incorrect, k00c while expecting tf701t).
Second: tried installing a custom ROM using Aroma, but the full wipe option didn't worked and ROM would boot loop!
Third: started using a modified ZIP of the original firmware without device identifier check, which was not allowed to install in stock recovery.
Bootloader was still on 10.26, however the closest thing to work was to flash original 11.4 firmware in CWM
At the end I use the original firmware ZIP and copied it to /sdcard/S4_SDUPDATE.zip, flashed stock recovery, and it installed flawlessly. That's when I realized the full wipe never occurred, all data where still there!

I need help 😞

i flash stock MOB31E rom using official TWRP 3.0.2.2 after i flash it my boot recovery was gone and only appeared is broken android with exclamation point

Probably your device's recovery replaced by stock recovery.
Inorder to prevent this , you shouldve uncheck mount system read-only.
Anyhow, now you can still root your phone and install a custom recovery with a tool!
if you wish I'll link it here!
BTW, your device isn't booting now?
Pls its ok to me but i dont have a pc
