How does one downgrade the firmware?

I have the Indian HTC one X rooted with 1.28.720.10 and can't find the RUU anywhere.
I've been facing a lot of problems with it - including the disk space mysteriously vanishing, (20 gigs gone in my case) and so I want to revert it to a stock unrooted state before returning it for a replacement.
Already seen this thread for the AT&T version, and the sdcard does not have a mmcblk0p23 as stated.
I have the RUU for an older version(1.26.720.2) from the RUU thread so I want to downgrade the firmware to that one.
Anyone tried a variation of the AT&T method? Or is there another way to downgrade the firmware...or am I SOL?

wrong place to ask for. for all type of question there is a veeery big Q&A thread qo and ask there

You can't downgrade the firmware once updated the hboot and radio. You'll have to wait till s- off is achieved for that. What you can do is flash a stock rom (1.26), flash stock recovery, re lock bootloader (in order) and then flash the 1.28, subsequently 1.29.x firmware update ruu. If you want to get rid of the sd space issue, why not flash one of the many 1.29.x and 2.x based roms on the forum?
Wrong section btw. Anyway, best of luck!
Thank me if I helped.... You know I'll do it again Oh, and by the way, Sent from my HTC One X

Yeah, you can't flash an RUU that would take the hboot to a previous version. A few Chinese sites mention the 1.28.720.10 RUU, but I can't translate from my phone.
As said, just install ARHD 7.1 or whatever if you're already unlocked.

Getting 5.x Lollipop Update on Rooted HTC ON M8 International

Hi all
Apologies if this is answered elsewhere but I cannot find any information on this for the life of me and it's driving me mad.
I have a notification stating that my 5.0 OTA update is ready but I can't install it due to the Custom Recovery on my device.
I followed this guide (http://forum.xda-developers.com/showthread.php?t=2701376) and flashed the 'stock' (not actually Stock - every link it CWM or TWRP) recovery but it didn't work and the update still fails. I think I read somewhere that something is different about this particular update.. that you need to have an 'untouched'/never rooted device?
Plllleeeeeeeeeeeeeease can someone steer me in the right direction so I can get this update sorted?
Thanks in advance.

have you made any system modifications to your current rom?
Also need CID and firmware version number
ALSO needs to be in Q&A (asked the mods to move)

Thanks for that.
No Mods to ROM, CID - HTC_001, Screenshots of software info:

ok so you have clean 3.29.401.9 stock rom installed, if not restore the nand available in my thread via TWRP. (may be best to do this as a fresh start)
Next install the 3.28.401.9 stock recovery.img from the first post in my thread.
hoprfully then u should be able to tale OTA automatically

every link is CWM or TWRP are stock Nandroid backup, not recovery.img
Look under Stock Recovery Images for the stock recovery

Thanks for your help, that seems to have done it.
The first time I didn't pay enough attention to my correct Software number (in my case 3.28.401.9). When I matched up my CID (HTC_001) I just picked a random link on that list which is why it didn't work.
Got it going now and back on custom recovery so thanks again for your assistance

Bricked HTC One M9 (managed to install TWRP 3.0)

Hi, forgive me if this is not the correct place for this but I am at a dead end with my struggles. I have an HTC One M9 that I managed to delete the OS & Recovery. I finally managed to get TWRP 3.0 back on it and when I try to install the OS (ViperOneM9_6.0.0) & Gapps it goes into a bootloader loop. All goes well throughout install process but I just cant get it to work. Can anyone PLEASE point me in the right direction, I've been w/o a phone for going on 3 months now.
P.S. If it helps at all it says developers edition and my carrier is MetroPCS (Tmobile)

I suspect that your firmware is out of date. Please post your OS version - that will help us know how to advise you.

Thank You. It doesn't have an OS Right now, could you be more specific about what you would need (format of the info possibly, or an example. I am fairly tech savy but have very little android internal experience)

Your OS version will come up regardless of whether you have a ROM installed. Check out the readme thread for how to use fastboot to pull the information.

this is the information of my phone :

First step of what? Are following a guide, like this one: https://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Anyway, it's not bricked (at least, probably not). It just won't boot. Did something happen to the phone that caused this condition?

You want the stock TWRP backup 6.12.111.4 from the above linked collection. It's the number on your getvar output "version main" as well as the OS number on the bootloader screen of the phone.

Hey Man , yeah it's not bricked it just got ****ed up during an update .
yes i followed the tutorial in the link u have attached and the ROM u suggested didn't work for me :/

On the bootloader screen, is the OS number in red font, or anything in parenthesis?
You might try to flash the firmware. But to do this, you will need to relock the bootloader, flash the firmware, then unlock the bootloader again, flash TWRP, and the stock TWRP backup 6.12.111.4
File for 6.12.111.4 firmware is on the following post (it's Post #5 of the same thread as before), with instructions on how to flash are at the end of the post.

No i don't think so ,

no there's no red number or parentheses as u can check here https://ibb.co/ivpY6R

Didn't work, meaning what? Stuck with no boot on HTC logo screen, or something else?

Question ROM flashing in TMO LE2127

Hello guys, I just got this phone upgrading from my OP5T and I used to flash roms and kernels with TWRP, I see things have changed and I would not like to destroy my phone. I have always liked

trying new roms and messing with my phone, would really like to be able to flash Nameless or PE. I have seen that if you get the TMobile variant things get a little tricky with firmwares and phone versions. I got my SIM unlocked and I already have my unlock file to unlock my bootloader. Havent done that because I dont really know if my ROM flash would work.
Do I need to unlock my bootloader?
Can I already flash my ROM files directly from adb or do I need to convert my phone to EU with TSM?
I have seen that people mess with modules that I need to backup, is this only needeed to convert to EU version or would I need this for Nameless
?
Do I flash firmwares via fastboot/adb or do they come with local updates? Which I do not have because of TMO.
I have already asked a couple questions in the forum but I need to clarify myself with ROM flashing and prerequerisites with my 2127 version. I would really appreciate some help about this, Ive never tried getting help from forums and looks like this phone community is pretty active.

Go to the Nameless thread and follow the instructions to the letter and you will be fine!

Is it really that easy? I do not have to do anything else before because of TMO?

No, just make sure you follow every step in sequence. Read the instructions a couple times to make sure you fully understand everything. Like are you suppose to be on Android 11 or 12 as an example.
