[Q] PROBLEM!!! Can't flash anything bellow ics

Hi! I have an lg OB running ics 4.0.4(V30B). The phone it's rooted and I have CWM installed from Rom Manager. I can acces Recovery from Rom Manager and with the phone off ( VOLUME PLUS + G KEY). The problem is that I can't flash any Rom bellow ics (not even with Smart Flash Tools) without getting bootloops. I can flash Roms based on ics and above( IZS,CM10.1,NAMELESS ROM NIGHTLIES 4.4.4).
Could someone help me?

I was hoping you fixed the issue. I don't know what to do.
It's a matter of unlocking the boot loader. Once you do that, you can jump back and forth between ICS-based ROMs and everything else.
Gingerbread ROMs include the boot loader (marvel and Huexxx).

Man I can flash ICS-based ROMs .JB and KK, I can't flash GB stock or GB-based ROMs, not even with SFT.
I think the bootloader it's unlocked because I can acces CWM from switch off phone(key combo)....I am confused because i read many tutorials but they are contradictory
That happends also with me 2 times.
Just flash CWM recovery again.

Try toii install a ROM right after rebooting from flash.
What I did is: Install a JB ROM, After, I reinstall CWM with ADB, reboot and then I could install any rom.

Did you unlocked the bootloader first? can you put a link with your froyo and SFT?
I am from Romania so I need an Europe Open
No, I don't tried to unlock bootloader, but like you , I got the bootloops every time I downgrade from ICS, Nameless or cyanogen roms . I use original Froyo - flashed with SFT , then upgrade to GB with Cwm recovery patch- flashed with SFT, then boot to recovery and install Nameless. I will give you the links, once I uploaded to my dropbox.

It's not working. Don't know what to try
UP! When I use the bootloader unlocker app the flashing process take about 2-3 seconds and the app closing by itself without any message like "succes". I even tried to flash a u-boot img uploaded by huexxx and at the second reboot the phone stucks on lg logo without flashing leds

Did you already try the alternative way without the app? Which means load the files to your sdcard and afterwards type the dd if=xxxx of=xxxx? This could show if it works or fails. And did you ever flash the LU5900 port? So the early ICS ROM released by Redy, Gabwerkz and me. Try the manual unlock first.

As written in the thread, type it into terminal emulator (an app). Read the thread carefully please.

OK I have the terminal emulator on my phone.
I've read the thread and it says "Move this two files, bootloader and recovery to the root of memory sdcard;
Enter in the command line
su
dd if=/sdcard/u-boot.img of=/dev/block/mmcblk0p2
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p4
And reboot or reboot recovery."
I have downloaded all on my laptop(bootloader recovery and su) but I am confuse....what's with that "su"?
Do I have to put it on the root of the sdcard too?
Sorry for my noob question

Stuck at reboot after flashed the new version of twrp

I have flashed the 3.2.1.0 version of twrp recovery but it stucks at reboot when i reboot the system well i don't know what to do if i flash the old versin 3.1.1.0 is it would be problem. Now i am on stock rom and recovery. Open for suggestions.
It may be a kernel problem. I had the same thing happen on stock. I fixed it by downloading a ROM then installing TWRP. After install go right into recovery after you disconnect from Odin and clean flash the new ROM. No problems after that.
Any errors on screen as it boots?

I used the latest TWRP and immediately flashed the Teleteam s8n8 ROM after installing TWRP. You can find the ROM on here with a quick search.

I have tried this method to solve my nvram err=0x10 , but it doesnt work . I did follow all the steps . Any alternative ? I'm facing wifi intermittent drop now . It's annoying
I tried the above method , reboot and it become nvram err=0x02 , why ? Any other solution ?

Also tried this , but it doesnt work also
If you don't have an nvram backup you can flash this zip:
https://www.needrom.com/download/nvram-imei-fix-for-k3-note/
It will give you a new shared IMEI (illegal technically) so here is a nice tutorial on how to change your IMEI manually:

I have broken pretty much every aspect of this K3 but it keeps on going, what a great phone.

Weird, what rom are you running? I get nvram error on every rom I flash now and this always fixed it. I'd say go back to the stock Lenovo rom via flashtools and try to fix the error from there, make a backup and then clean flash everything.

Depending on how you formatted can cause serious problems, I broke my last phone because I was messing around on flashtools and formatted the wrong thing. I am running dotOs and got nvram error and that fix I posted earlier solved it. Can you try that rom from needrom?

problem with twrp

Hi I screwd up when flashing roms and returned to stock so everything is clean I have flashed twrp again and whenever I try to flash a zip file whether it's a rom or gapps twrp reboots itself back into recovery I'm all out of ideas. I might have to stay in stock if I can't go fully custom again

Camera not working after some flashing

So basically I unlocked my mi 8 and tried some of the roms and kernels. First I flashed the twrp recovery. I flashed two roms. After that I forget about the zip that disables the verification, I got the popular issue where the recovery doesn't open after flashing it. Then I found the solution and installed the official rom via fastboot, then I flashed the recovery the proper way. Everything was fine, I flashed the official pie 9 rom again, I also flashed the eXtremeKernel V2. Later I noticed that when I open the camera it doesn't show anything on it. I tried using a third party camera app (OpenCamera) it didn't worked either. I'm sorry for the way I wrote it (it's a bit unlogical) but I hope someone can help me out with this. Thanks
Flash last official rom via mi flash (!!!!!! CHANGE CHECKBOX FROM CLEAN ALL AND LOCK TO CLEAN ALL!!!). Load installed ROM and open camera, if it's working go to flash costum ROM. And it's should work without problems.
Thanks for help I tried that but it's not working :/
