Help! Trying to revert to stock rooted from CM10

I upgraded to CM10 from the original OS and I am using the latest version to root my phone, I am using TWRP. Anyway, Everything worked fine, I rooted the phone, I upgraded to CM10. I want to go back to the original OS. I downloaded [ROM][8/3] - Stock Rooted AT&T 2.20.502.7 - Android 4.0.4 - Odex or De-Odex, I got the ODEX version, I flashed it to my phone but its just hangs at the HTC One X Splash screen with the red lettering. What am I missing here? I can get back into recovery and I backed up my old ROM just in case.

How long are you letting it hang for? Try 2 more power downs and power ons. The first few times it took about 5 min to load.

It just shuts off and turns back on again, it basically loops. Did I download the wrong file maybe? Is there a specific ROM I need other than the one I mentioned earlier?

Factory reset, wipe system, flash ROM, wipe cache and delvik.
Any time you go from non sense to sense or vise versa you have to wipe the system and factory reset.

This was the ROM that worked when i did it.

He mentioned in another thread that he did those steps. The only other thing I would try is to flash the boot.IMG from the ROM you want to use

I still want to keep my phone rooted. This wont kill the root right?

No the ROM posted above is stock rooted
But if you made a backup as you said in the first post why are you not just restoring the backup?

Basically where I am right now. I downloaded the original OS, by following instructions, I have managed to delete my backed up rom of CM10 that i backed up earlier. I was able to FLASH the OS I wanted, I flashed the boot.img file using fastboot. I restarted the phone and now its just stuck on the HTC Quietly Brilliant screen with the red lettering at the bottom. It doesn't restart or anything, it just hangs there. What am I missing here guys? ):

I'm going to install cm10 right now them go back to stock rooted and see what's up with this

There's no issues going back and forth. You probably flashed a bad ROM

yea, your most likely just doing it wrong. you need to do a full wipe and flash boot.img
answer: oh yea cant flash the stock rom using twrp 2.3.1.0 you will need to flash twrp 2.2.2.0 then flash stock rom. that is actually most likely your problem.

What hboot are you on? If you separately flashed boot.img from CM10 via fastboot, you might need to again separately flash the boot.img from the stock ROM. Also remember that the procedure employed to root 2.20 is substantially different from the root procedure to root the previous build of stock. Not sure what software you rooted, or whether this would pose a problem, but it's a consideration.
Another option is to just restore to stock via RUU and re-unlock, re-root, if nothing else works. Getting stuck on HTC splash screen sounds like a boot.img issue. Good luck.

Really? Why is that?
Just curious, I haven't heard this before. Is this a known issue with flashing the 2.20 stock ROM? I haven't seen any cases of ROMs (stock rooted or otherwise) being sensitive to version of TWRP. At least not the case of having to use an older version (keeping TWRP updated is usually the recommendation).
Of course, just because I haven't heard of it, doesn't mean it didn't happen!

Did you fastboot flash boot boot.img?

im assuming the age of the stock rooted would have conflicts with the new twrp. i have had problems with roms not flashing with newest twrp. it is also a known problem since twrp 2.3.1.0 release.

[Q] Accidentally wiped system, how to revert back to stock without losing root?

So i accidentally wiped the system using twrp. But i got it to work by using a usb flash drive n flashing a custom rom from there (paranoif android) And now ive been getting random reboots and crashes. I also flashed franco kernel. Also some system apps will not work properly, such as the calendar app. And i was thinking maybe thats because i wiped the system. Now i want to revert back to stock kikat without losing my root and unlocked bootloader. Im quite new to flashing roms and i find it easy using twrp. So how do i go about reverting back to stock, to see if those random crashes and reboots will go away?

Try re-flashing another rom, as PA is a beta ROM, and thats where you may be having your crashed apps

You can always flash the factory images here: http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
You can flash any ROM and that should fix your issue
You will not lose your unlocked bootloader unless you flash the stock one which is in the factory images

Your bootloader will not relock unless you lock it yourself using fastboot. Flashing roms or factory images won't lock it by themselves.
And even if it somehow did, one fastboot command and you're unlocked again.
And as far as root goes....it takes 5 minutes to reroot.
So just flash whatever factory image you need and then custom recovery, and you're done. Maybe need to download superSU from play store after.

So i just flashed purity rom, and im still having the same issues, but the crashes and reboots are less yet their still there. Maybe reverting back to stock rom will do the trick?

The crashes and reboots are because you didn't wipe data/factory reset and also didn't wipe dalvic/cache...
If you're keen on using a custom rom follow these steps:
1. Head over to recovery and wipe data/factory reset and wipe dalvic/cache
2. Flash rom.zip and gapps.zip
3. Reboot!
Initial boot can take upto 10 minutes sometimes so be patient...
If you want to go fully stock then follow this thread:

Sorry if i did not include this on the op, but everytime i were to flash a rom or gapps i would wipe data/factory and dalvic/cache, since i had those issues i even wipe internal memory just to see if the problems were there.

Maybe your flashing a bad version of GApps since the force closes are on google Calander?
Are you using a 4.4.2 GApps?

Im on cataclysm now, and i believe no gapps needed since their included in the zip. Have had about 3 reboots, i believe their because of playstore downloading an update or something, and one caused by either bluetooth or hello messaging app. But who knows. Just one more thing, by me accidentally wiping the system shouldnt be the cause of my random crashes and reboots?

Why don`t you backup your user apps and data with TB and start fresh by flashing the stock image, reroot and reflash a custom rom in recovery. This will eliminate all errors and reboots.

Yes, just flash the factory image (flash-all.batt) in fastboot, reboot and setup the phone. Flash a custom recovery and flash the superSU.zip (1.94 is the latest).

(Q)How to stay up to date while rooted?

Rooted with CWM as recovery. Shield Tablet has OTA update but obviously can't install with CWM. What is the simplest way to stay up to date and keep root?
Sent from my SHIELD Tablet using xda premium

Still looking for help with this. I have a basic understanding on how things work. Is this what I need to do?
Flash original recovery
Reboot then do the OTA update
Then refresh CWM
Will I lose root?

That's not the way to go at all.
Whenever there's an update, flash the incremental OTA file HERE.
Flashing the stock recovery will not allow taking OTA's.

thank you for the link, which command do I use to flash the incremental update looks like the instructions there are for a full update. thanks again

Um, just flash it in TWRP or CWM, only need to flash cache and dalvik cache, but that's optional.

Im also sorta nooby about this. The only thing I have ever done is flash Cyanogen Mod and install TWRP on my Galaxy Note 3. I have rooted my Shield and installed Uno TWRP out of the box. Thus its not on the latest update. Just to clarify so I don't f*ck up. I just download the latest OTA, copy to my sdcard and flash in TWRP? And that will just update it without having to lose all my apps etc?
EDIT: So incremental updates take from version x.x to version x.x? Oh, and is it true that root is wiped? Im happy to re-root everytime.

Yes that's true, just make sure you flash the incremental updates and not the full OTA's. And as far as root I'm not sure if you loose it, while in recovery might as well just flash SuperSU to be safe.

Ok thanks. One more question. How would I go about checking the rom version? Unless I'm missing it I can only see the Android version, which is 5.0.
EDIT: i'm getting some sort of error when trying to flash the zips. I downloaded (for wifi) 2.0 to 2.1, 2.1 to 2.2 and 2.2 to 2.2.1. Whenever I try to flash it just fails.

Yes, because you need to flash 2.2.1 full ota via custom recovery, and wipe cache dalvik. Then flash again your custom recovery. Then supersu.
If you are rooted with custom rec (twrp, cwm, Philz) you need to flash full ota.

Wouldn't the tablet be wiped then? And if this is the case everytime can't I just keep the stock recovery and sideboard a custom one?

Nope. You just flash on top, like a dirty flash. I use TWRP and Ive done it twice and still kept everything. The only wipe you need to do is cache & dalvik after flashing full OTA.
If you keep stock rec just for the fact of being rooted incremental OTAs wont work

I just flashed full OTA via CWM and lost root.
I had to re fastboot flash recovery and then sideload supersu to root.
It sounds like TWRP is holding root.

my device (moto G (falcon) XT1032) is a GPE device.
in the last 2 days i tried to install CM 13 on my device.
i tried 3 different recoveries** - CWM, TWRP and CM recovery - to install cm-13.0-20160206-NIGHTLY-falcon (and yes, i checked before flashing, the SHA1).
in all those tryouts i always get into the sentence in the headline - Patching system image unconditionally... - and it just stays there forever.
one time i waited 40 minutes, and it still stayed on this message, and do nothing.
every time before flashing the rom, i wiped the device (dalvik cache, cache, system, Data).
i also try to flash the latest snapshot (cm-12.1-20151117-SNAPSHOT-YOG7DAO1K9-falcon) because i thought maybe there is a problem with the latest nightly.
i still stuck in the same stage(Patching system image unconditionally...).
i also try to flash stock rom 4.4.4 from motorola (from here: http://goo.gl/xAomMi) which succeeded, and then wipe device(factory reset and wipe dalvik cache, cache, system, Data) and install again cm-13.0-20160206-NIGHTLY-falcon, and it also didn't work.

No Flash Stock KitKat From Firmware via boot loader .

i think i'll pass.
i already flash kitkat and after that CM11 and it didn't help me to get into CM13.
i'm tired of flashing and restoring again and again.
thanks a lot for your help

As you wish...

I followed your steps too and i am exactly facing your problems, i am stuck in "patching system image unconditionally"...

Am I clean flashing correctly?

Hey guys I'm new to owning this device and just wanted to know if I have to reflash my firmware after clean flash?
This is what I do
Wipe System/Data/Art/Cache
From there I Flash Firmware/ROM/gapps
Is the firmware step required? Or can I just skip that step once I alreday flashed it previously?
I'm asking this question because I've been having some major issues flashing roms where they flash successfully but frankly just don't boot. I'm just not sure if I'm doing this correctly.

Clean flash involves wiping
/system /data /dalvik /cache
Then flash ROM + gapps
If you flash current firmware it should show 241 baseband in About Phone. Only need to do it once. No need to do every time you flash. CM nightlies do include firmware in their zips so by default will flash the firmware or at least check if its updated every nightly.
Use TWRP 2.8.6.0 or 3.0.0-1 which are versions known to flash firmware correctly.
If you flashed COS12.1.1 fastboot zip at any point in time your data and cache partitions will be F2FS and only certain ROMs will work with that. AOSP based ROMs most likely won't boot.

Appreciate the the reply! I'm going to restore to stock, and do it all over and update the baseband/firmware from there. Just to be safe ?
