[Q] Stock recovery (NoCWM) - GT540 Optimus General

I've search the forums and couldn't find what I'm looking for.
what I want to do is restore my LG GT540 bac to 2.1 so that I won't have fastboot or CWM recovery.
is this possoble?

You can use cwm to recover and boot into fastboot. Now you flash boot appsboot.mbn of official ROM (kdz file). It is safe than kdz update. Sorry for bad English.

or flash any 2.1 stock rom and use mur4iks bootloader builder to remove recovery and fastboot

[Q] Forgot to reboot after oem unlock - now stuck at boot

Hi
Please help! I unlocked the bootloader by using
fastboot unlock oem
after that I forgot to reboot and installed
fastboot flash recovery twrp.name.file
now I'm stocked at bootup and twrp is asking for password.
How can I fix this?
Could I flash the stock boot.img again?
ROM is stock OTA 4.4.2.
I know about flashing a factory image. I would like to find a way to save my data first, if possible.
Many thanks for your help!!!!!!!

Wipe cache from twrp, this is happened to me too But for the password i don't know...maybe reflash twrp, boot.img is the kernel so in my opinion flashing it wouldn't help you
Did you flash straight from 4.2.2 to after installing twrp? I did the same thing. I had to flash back to stock 4.2.2, install twrp, connect the phone to my computer, choose accept at RSA message, and fastboot flash to 4.4.2.

[Q] Eclair 2.1 rom

I was looking for a light 2.1 rom and found this one: http://forum.xda-developers.com/showthread.php?t=1038337 (Lite edition)
Being a beginner, i got a few questions.
Do i need my phone flashed to V20E using .kdz beforehand? My current is V20B + fastboot.
There is kernel img provided, but iam not sure how to use it.
Which clockwork recovery do i need? As i understand 2.1 roms can only be flashed with old recoveries, such as 2.5.x.x . My current version is 3.0.2.4.
Thanks.
Img files can be flashed via fastboot commands:
on your PC type:
fastboot devices (makes sure its recognized)
fastboot -w (wipes data, cache)
fastboot erase boot
fastboot erase system
fastboot flash system system.img
fastboot flash boot boot.img
fastboot reboot
You'll need the fastboot drivers to be installed of course
Tnx for fast reply.
But do i need V20E.kdz rom specifically and flash my phone with KDZ updater? I couldnt find working links for V20E.kdz, only A,B&C.

You tried to install a factory stock ROM with twrp recovery? I should read some more threads before you start flashing ROMs. You can only flash factory stock ROMs with your PC and fastboot/adb drivers installed and software like rsd lite.

System delete..

Hello! I have an P8Lite ALE-L21 unlocked and by mistake I delete the system.. Now I don't have OS to boot
What can I do now to have back?
Download the rom for your phone then install the rom using the recovery system op the phone.
If that doesn't work try flashing the rom through fastboot.

I tried both but it dosen't work
I don't find source with system.img
Use this http://forum.xda-developers.com/showthread.php?t=2433454&page=31 to extract the system.img
- Fastboot flash boot boot.img
- Fastboot flash recovery recovery.img
- Fastboot flash cust cust.img
- Fastboot flash system system.img
- Fastboot reboot
Use those commands and I hope it will be fixed.

Moto X Pure XT1575 Stuck at bootloader unlocked screen and stuck at twrp logo

So i was recording a video, when it entered a state where I had to reboot the phone. I did so, and it got stuck. I did a hard reset. The phone then gets stuck at bootloader unlocked. I entered fastboot, selected recovery, and it gets stuck at the twrp logo. Any ideas? I also re-flashed twrp and it still get stuck.
Can you boot TWRP with 'fastboot boot twrp.img' and do anything? (Replace 'twrp.img' with your TWRP image filename)
If not, try fastboot flashing back to stock, but it kind of sounds like your emmc (internal storage chip) might have take a dump. Very unusual, but not unheard of.

I used a restore-to-stock tool. It didn't actually restore me to stock. I have NO CLUE what it did, but suddenly i saw my custom boot animation again, and was able to boot into twrp, altough my nandroids are gone. I flashed a rom, and it didn't recognize the sim card. I flashed a new rom, and it recognizes the card, but i get no service (in my house where i always get service). Any ideas?

This is why one-click tools are bad... You need to flash the full stock image manually, and not downgrade, you must use the same or newer version of stock firmware than you device last had installed.

No, I don't think so, but you could do it like this:
Code:
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot flash bluetooth BTFM.bin (optional)

Only with twrp you can save your data.
What version did you used? Try with another, maybe don't flash - only boot.
"fastboot boot NameOfTwrp.img"
If it boot copy your data to pc.
Stock you can flash with fastboot, here is "how to", download and flash the highest version for you model:

Read carefully, don't lock bootloader.
