I have ruu version of stock rom but cant install them. It is some problem with phone driver for windows 8.1

Well you can find it as a PC10IMG.zip and place it on SD, you can flash a stock based ROM from recovery which there are many of, you can use a different PC to flash with fastboot, or you can get the drivers working
I have used fastboot many time on 8.1, an easy way for you is discussed in this thread

use ODIN to flash your phone with stock ROMS.
How do we get ODIN?
Sent from my PG86100 using XDA App
where to get odin.can any one send me link.
you do NOT use odin with htc phones. you can run .exe RUU files on your pc(similar concept to odin),or you can flash IMG files in HBOOT.
there are a couple things you can do:
1)flash a new rom in recocovery. remember youll have to flash GAPPS seperately with most AOSP roms. look for custom roms here: http://forum.xda-developers.com/forumdisplay.php?f=559&order=desc
2)flash a stock rom in HBOOT or as an RUU. shipped roms can be found here: http://www.shipped-roms.com/index.php?category=android&model=Passion (Nexus One)

[Q] Samsung S3 (cyanogenMod) unlock

Hi,
I bought a locked Samsung S3 (At&t). It is rooted with cyanogenMod 10.2 Android 4.3.1. All i was trying to do is unlock it so i can use it with other carrier. So i bought the unlock codes for 30 bucks but later i found out that the unlock codes only work with Stock rom. I am not an expert at this Root, Custom Rom...stuff, but not idiot either i can follow step by step directions if anyone knows how to make this work. I would like to use the custom rom though, so do i have to recover in stock rom, unlock the phone using the code and than install the custom rom again?
Plz help

Yes, that is what you will need to do. As you can only enter an unlock code on a stock ROM (or one of the numerous custom ROM based on the stock one), you won't be able to make it work on CyanogenMod or any AOSP derivatives. You will have to revert back to stock, then (if you want to try a cutom ROM) install another custom ROM of your choice, be it CM or anything else.
Though if you currently have CM installed in your device, you most certainly already have a custom recovery (TWRP, CWM, PhilZ Touch...), which make it even easier for you to flash ROMs at your will -- the step of installing a custom recovery is already done. So browse the AT&T SIII Android Development forum, choose a stock-based ROM, install it -- pay close attention to the installation instructions in the ROM's thread --, unlock your phone; then repeat those steps to install another ROM if you want to.

Could you please direct me to how to unroot? I am able to go into the recovery mode but not really sure how to go on from there. I appreciate the help.

Before you flash a stock ROM, you would need to check what bootloader your phone is currently on as flashing the wrong one could cause your phone to brick or become unusable. Custom ROMs like the CM you currently have do not have their own bootloaders but rely on manufacturer's bootloader to run. The bootloader, quite simply, is a small application that loads the operating system and all other applications & systems required for the phone to run once it is powered on. Therefore, with a faulty bootloader, your phone can not gather all the resources required to power on successfully. If your phone is running on the 4.3 bootloader which would be the case if it was on 4.3 before the update to a custom ROM, then you would have to return to stock Android 4.3 which is the latest OS available for the AT&T GS3. However, if it has an older bootloader, then you can flash Android 4.1.1 via Odin.
There are different sets of instructions for either system so I would suggest you check your phone's settings and advise the OS parameters you can see there so we can steer you in the correct direction.

Did the phone originally have 4.3? or did it have an older version before you installed CM 10.2. This would determine how you would go about it.
Also is there a custom recovery like clockworkmod installed?

[Q] Can I restore back my Z1 Compact to stock using a custom recovery?

Hi guys! I want to get back to stock firmware without using Sony's flash tool. I am on Ubuntu and I believed that there is a version of flash tool available for it, but the problem is my laptop doesn't recognize the phone at all. Tried a lot of things already but it still doesn't detect my phone.
I am running CM12 and I have a TWRP installed. Can I revert back to stock even w/o using flash tool? If yes, can you guide me how to? I am pretty new in the world of flashing so please bare with me. :angel:
Well... A custom ROM is a custom ROM. It is the exact opposite of stock.
If you really want to go back to stock (which means unroot and clean install without modification) then you have to go with the flash tool. Where is the problem there? It is really easy to use and there are plenty of guides.
If you just want a stock based ROM (which means custom ROM with the feeling and interface of stock Sony) then you can flash one. There are severals here on XDA. Just look in the dev sections.
Not recognizing phone means lack of drivers.
Seek forum, it was described for sure, myself i added drivers too then it is not mystery.

Question

Tired of waiting for the MM OTA, I decided to convert my HTC M8 to developer edition.
I've already unlock/root/custom recovery and i got stuck at the s-off. I found out that i need to pay for that and I decided to stop my journey.
Now I'm thinking of flashing a 6.0 MM custom rom based. My question is : What should I do before I flash any custom ROM?
I'm thinking to go back to stock soon and I don't want to mess it up forgeting something.
You need an unlocked bootloader
You need latest lollipop firmware at least when there is no MM firmware yet for your device version - it is a 4.xx.xxx.x firmware
You need to install TWRP 2.8.7.0
You need to install custom ROM (either lollipop or MM base)
Thanks but I think you misunderstand me.
My HTC is already prepared to flash custom rom. I was wondering if i need something to do before i flash my first custom. Something that will help me to go back to stock when i need it.
Make a non-rooted nandroid of your stock ROM. You need it to revert to stock for future OTA or simply back to stock reason.
If you not yet done it, seems it is too late for you because you already root your stock ROM as stated on post #1.
Check my thread link in my signature to see whether there is one non-rooted backup for you.
Yeah, I've already root it
But I found this http://forum.xda-developers.com/showthread.php?t=2265618.
I think maybe this will help me .
Your thread help me too.
Thanks
Err... that link is for M7 ... don't know whether that helps.

Downgrade from LP to KK

Can't seem to find anything on this and hoping someone could help me. I'm looking to downgrade from LP 5.1.1 back to KK. Can I just flash a KK rom or do I need to go back to complete stock and then upgrade to KK?
If your rooted and its a custom rom you should be able to bounce back and forth. I am running 4.x now but install the 5.x and 6.x roms to try them often and have no problems.

alright well give it a try.. just didn't want to brick the device. thanks.
I haven't bricked one yet and if anyone has that kind of luck it's me. Make sure your modem is upgraded.
The LP on the phone must be a custom ROM rather than a stock ROM as there is no stock LP ROM and custom ROMs do not touch the modem or bootloader during the flash process so flashing a KK custom over an LP custom should not be an issue.
