I don't understand these directions from the FAQ:
"Q. How to get back to stock? I need to give my phone to warranty services how do I revert to official LG rom?
A. Check this thread. It is the v10b 2.2 stock rom as a flashable zip package. If you can't access the recovery, then see if the firmware for your country is available here or use this tool. Download the firmware and use the KDZ tool to flash. You will find instructions to use the KDZ tool on this thread. For a picture guide, check this thread.
Also for official GB lovers, see this and this. It is a v20g rom in flashable zip package. Or if you'd rather flash v20c/g roms from LGMDP, the links for that can be found in this thread.
If you are on Optimus V, see http://forum.xda-developers.com/show....php?t=1025911
If you are on the Optimus T, see this post. Uses the KDZ method.
Q. How do I restore the stock recovery?
A. Download the original recovery zip file from here and flash it. (Yes, you can flash a recovery from within recovery itself)"
I have LG P500 from USA T-Mobile. I'm on V20 Baseband.
1)Is kdz the only way to go back to stock?
2)Which way is the safer and better way to get back to stock?
3)How (full instructions) to get back to stock rom for USA T-Mobile?
4)How (full instructions) to get back to stock recovery for USA T-Mobile?
yes you can flash a recovery from recovery, if it is a flashable zip
you need to stick with your phone not other variants of LG p500, O-1(Europe), O-T or O-V, dunno what is the T-mobile USA version, but is it written inside your phone under battery
1) KDZ is for flashing software in your phone, but beware, if you are unexperienced you may brick your phone for good, but you can try it, DO NOT PULL OUT BATTERY OR DO SOMETHING WHILE KDZ IS NOT FINISHED FLASHING PHONE OR YOU WILL HARDBRICK IT (but, I do not think someone at service will notice that, after a hardbrick, it just went dead and nothing else, nobody knows nothing)
2)if you do not know what are you doing, nothing is safe, anyway, as I mentioned, a hardbrick is a hardbrick and if you still have warranty, you are lucky
3)http://forum.xda-developers.com/showthread.php?t=1824618 search there
4) LG P500 doesn't have stock recovery(just bootloader)
if you do not know what to flash try to find a T-mobile rom image (MAKE A REQUEST-someone will post it), and first time when flashing a recovery is to backup original rom for what will come after
LGMDP will work like this, it upgrades rom when you have an older version, so try to flash an older custom rom, find an Froyo 2.2 and flash it as any custom rom, boot, conect your phone to PC, that means that you have LG USB drivers installed, start LGMDP and w8 to detect your phone, after that goto options & help, select country, carrier, phone, w8 to detect latest update, start update
in case that your phone is not detected, boot into recovery, goto mounts and mount USB, that will make LGMDP detect your phone, start updating

KDZ is generally discouraged . However if you can find a Nandroid back up of GB , then that would be the safest way . I went back to stock froyo with the help of this thread - http://forum.xda-developers.com/showthread.php?t=1955354

Your have V20 that is new baseband so any rom from GingerBread onwards is good for you . Stock recovery can be flashed sitting right from custom recovery . Check out this thread for custom recovery and ROM of 2.3.3 - http://forum.xda-developers.com/showthread.php?t=1309744 .

So here I am worrying about bricking my device if I go back to stock.
Here is some insight-
I have an unlocked XT1032 US retail moto g running Cyanogenmod 11 m4 snapshot. I am also running clockworkmod recovery and everything is working fine. I have heard of many people bricking their devices when they try and flash stock because the version doesnt match up with the bootloader version or something like that. My bootloader version is reported to be 4111.5 (The bootloader menu version is 41.11) from the "fastboot getvar all". So if I want to flash stock firmware what version do I need to choose. (can someone give me a link to the download?) Also is there any easier way to do this, perhaps can someone give me a clockworkmod backup of stock firmware and i can flash it via restore in the recovery. Also is there a way to get .img files of my whole phone via the dd command on the superuser shell. (Someone please give me a list of those commands to make a full image of my phone) so I can restore incase something goes wrong.
So pretty much all in all can someone please give me a link to the correct stock firmware for my phone that I can flash with NO issues and a list of commands that I can use to flash.
And just wondering what is mfastboot and how is it different from fastboot.
I should have made a backup with cwm recovery before I installed cm11 but I forgot which is why I made this thread. ALL HELP IS APPRECIATED! THANKS!
hey try downloading stock firmware from this link http://sbf.droid-developers.org/download.php?device=14&file=786

just make sure you choose firmware which is for retail US and also choose right version of android... but first try the firmware i have mentioned above...

during flash gpt.bin it said preflash valadition failed and on the bootloader screen it said partition table downgraded. Used CWM backup to restore and my phone is functioning again but I am still not stock. Please tell me what I am doing wrong? I have attached a screenshot of the command prompt screen.
Q30: i encounter '(bootloader) Preflash validation failed' error message when flashing Firmware Image
You may have updated to Android 4.4.4 via firmware image or OTA update. In this case you now also have the latest version of the Bootloader. That is why you get the above output when attempting to flash a 4.4.2 firmware image. ==> simply flash 4.4.4 images instead.
If the error still occurs, even with a 4.4.4 firmware image, then unlocking bootloader will be necessary.

There is no 4.4.4 Retail US yet. You can flash 4.4.4 Retail EU just fine. Recovery flashable zip here:
http://forum.xda-developers.com/moto-g/development/rom-stock-motorola-rom-collection-t2854688
I have the retail us version though. She. Will the retail us 4.4.4 be available? And one important question when I do go back to stock 4.4.4 with the link you gave me via recovery, will my custom recovery get overwritten with the stock one?
XT1032 is a Global GSM model. you can flash an XT1032 ROM from anywhere in the world and it will work.
It's currently unknown when 4.4.4 US Retail will be available, but I do not think it will take too much longer.
Those zip files only include ROM and Kernel. Recovery will not be changed.
I'll be trying that tomorrow and I'll let you know if it works or not asap. But for now thanks!
You might also need to flash the 4.4.4 EU Retail radio zip available here:

I read somewhere that when you flash stock ROM even though the recovery is not being changed, the stock ROM will overwrite the custom recovery in start up.
Is this true?

Please help my phone is stuck in CWM recovery during the flash and I think the recovery is frozen. Can I hard reboot back to recovery or is my phone totaled? :crying:
This worked for me - http://forum.xda-developers.com/mot...-gpe-4-4-4-t2824377/post55768571#post55768571. Once back to 'base' you can update to 4.4.4 OTA or flash another ROM. And if you get stuck again, re-run this process. Three downloads, a few scripts to run; double-click easy.
Good luck.
Back at stock, just had to give CWM 10mins! Thanks everyone!
Hi,
It's been years that I've been living with the XT925 on CM11 JBBL and as I've been following latest developments on CM 12.1 and want to give it a try.
I've been searching for the past week on how to safely perform the bootloader upgrade so I can flash CM12.1. As it turns out there is a lot of disperse information on how to do it, followed by scary cases of soft bricked devices.
Current device status:
- Bootloader Unlocked
- Rooted
- CM11 M12 JBBL
- Everything works fine
What I already know:
- I have to Unroot my device
- Need to flash stock 4.1.2
- Must check if everything works once in stock
What I need help:
- Should I download OTA via the stock firmware?
- Should I flash stock recovery?
- Should I perform the update from the device or should I extract the OTA and change something and then flash it manualy?
- Is there any tutorial that I should've found on my searches?
On a sidenote: is there any chance of my bootloader to be relocked and/or loose any chance of future root access due to the OTA?
I believe that as people realise that CM12.1 is stable some noob friendly thread to the ancient JBBL's out there would be much apreciated.
Thanks in advance!
If I were you, I would just flash straight to KK with RSD or House of Moto. If you go this route, you won't need to flash back or reinstall stock recovery. Flashing the FXZ will reinstall stock recovery, but if you use House of Moto you can use an option to flash aftermarket recovery. Flashing shouldn't relock your boot loader, either.

In order to flash straight to KK I need to obtain it via OTA download while in Stock JB.
I haven't found any KK image laying arround, so this might be the only route.
Any other advices will be much apreciated RikRong.
Can you find the firmware on MotoFirmware.com, when it's actually up?
Try this: http://motofirmware.center/files/

The only one firmware for xt925 available is from Canda Retail, here is the link
Hi,
I´m a neewbie to Samsung. My phone is a S6 SM-G920F, Baseband G920FXXU1AOCW
I came form an HTC and I´ve seen that flashing things are very different. So here are my questions:
1. I think, my bootloader is unlocked but I didin´t know for sure. So how can I check this?
(My HTV showed me this by using fastboot, didn´t know if there is fastboot with Samsung and how to start it - only know the download-mode and how to enter TWRP recovery)
2. Flashing firmware via Odin (i. e. from sammobile.com) means to loose my root again, right?
3. If I loose root, where do I get custom Firmwares and how do I flash them (if this is possible)?
4. If not, is it enough to flash bootloader and modem through Odin?
All answers are appreciated. Thanks in advanced.
Maybe someone can link me to an step to step instruction...
Fastboot is android doesn't matter who makes the phone.
If you flash a rom from sammobile then you will go to whichever stock you pick.
Other ROMs are available here. The phone is new. There aren't many yet. Cyanogen mod isn't available yet.
Root is available by flashing cfautoroot with Odin. You will need to get the specific one.
You can replace the recovery by flashing twrp team win recovery project with Odin.
You can flash boot loader and modem. Make sure you get the right region. The modem frequencies are different in different places.
You may find flashing a whole ROM even stock will fail. This is because the partitions are not the same size for all s6 stock ROMs. Don't ask me why. You can open the tar find which file stopped the flash delete it from the tar and flash again.

Thanks for answering. My questions had an other intention, I think.
My S6 is already rooted and I have a custom recovery (TWRP) :good:
I would like to know if you have to flash a whole firmware or only bootloader/modem? Because I didn´t seen a post here for a full firmware yet.
I am not familiar with the differences between htc whole firmware and samsung bootloader/modem
Actually I am on Firmware G920FXXU1AOCW. But there are newer ones like XXU1AOE3 or XXU1AOE4.
In the days of my htc you couldn´t flash only bootloader or modem, you had to flash a whole firmware (like radio, drivers, bootloader, modem etc.)
Flashing only modem and bootloader will it update i. e. touchscreen drivers? If not, where do I get this ones? You know, because of root I don´t get OTA´s anymore...
The modem just controls how your phone hardware connects to carrier towers etc.
The boot loader is a tiny thing that tells the processor where and how to load the OS.
The software for pretty much everything is in /system.
Many of these releases are the same software, region specific. The dates are fairly unimportant for the same version number. They generally reference the time when they were uploaded by someone. Not that they have updates and fixes.
Just wanted to know can I change my phone logo MetroPCS to say T-mobile with all the T-mobile add on. I have a Samsung Galaxy s6 by MetroPCS
I have a D800, recently unbricked by shorting pins, and i have managed to install TWRP and download mode is working. I can't run any rom. I need to flash a KDZ through download mode.
But all the KDZ are of 10a/10b etc , does any body know where I can find a 30x KDZ or how to upgrade without flashing numerous FOTAs?
or will my phone boot up if i install http://forum.xda-developers.com/devdb/project/dl/?id=13450? i think not, but still need to know.

The AT&T D800 uses a TOT file to flash back to stock. Are you in the right section? If you have a D800 you can use this to go back to KK and it's just one FOTA thru AT&T to go to LP. http://forum.xda-developers.com/showthread.php?t=2663369
I got the phone from eBay and it has been rooted when it came out of the package. However, I failed to activate it to Sprint. The Sprint customer service representative told me to flash the original stock ROM. The current rooted software version is ZV6. I downloaded the ZV5.tot file and ZV6.img file from this forum, however I don't know how to flash them.
It seems tot file is from LG and the img file is from 3rd party, so I prefer to use tot file. However, someone in this forum said you would brick your device if you flash different version. Maybe to flash img file is safer.
Any helps will be appreciated.
Do not flash that phone with the TOT file. You will hard brick it!! Follow this guide to flash back the stock system.img, but make sure you flash the correct version! You MUST flash version ZV6. Once you flash the stock image, you can reflash with the rooted image. Although I can't see the rooted image keeping you from authenticating with Sprint... seems to work fine for me. But I would give reflashing ZV6 system.img a try. Should work fine. (I have done this process many times with no issues)
