[Q] Downgrade from 9.30 - RAZR HD Q&A, Help & Troubleshooting

I would like to try the kitkat leak but when I try to sbf back to 9.16 rsdlite says it can't downgrade. How do I proceed? I have an unlocked bootloader.

use the 1.21 utility from the dev forum. otherwise you need to edit the sbf file before it will work in rsd.

Trying to revert to stock hboot

I tried following this guide:
thunderboltforums.com/forum/htc-thundebolt-hacking-guides/2849-how-restore-stock-rooted-non-rooted-users.html
I successfully flashed MR1, now when I go to flash the bootloader using the same PG05IMG.zip method it says bypassed. I checked the md5 hash, it checked out okay. What would cause this?
This is for a warranty replacement, I just need the phone to be stock again!
Just find the latest unrooted gingerbread rom that leaked and flash it, it will go back to stock. check here or android police for the download....

Thanks, I will give that a shot.
If you originally used the Revolutionary root method, its not just flashing a new hboot, as its a hboot that doesn't allow it to be easily overwritten. This stops you from accidentally flashing a s-on hboot at a time you didn't mean to (most likely through ruu). If you did that, you have to adb some files to your phone to put a stock s-on hboot on. If you did the old downgrade root method, i would try downloaded the files from somewhere other than where you did this time, and try again.

This is exactly what I needed to know.
For people in the same boat this is what I did (sorry for the links, apparently I don't have enough posts)
Follow this guide to flash a different hboot:
thunderboltforums.com/forum/htc-thundebolt-hacking-guides/5427-rs-guide-how-return-stock-revolutionary-root.html
Then flash the PG05IMG from here:

so to get back to stock, if you didnt use the rev root method, what exactly do you flash? could someone link me?

What I outlined above should get you to stock.
even if i rooted the normal way and not rev?

2/3 of the way down under this section "Putting current stock firmware and s-on back onto the phone"
This will put you back to STOCK / S-0N from the old downgrade root method. If you just want a stock rooted rom, flash one. Unless you are taking it in for service or returning it, there really isn't a need to unroot it just to put a stock rom on.

bootloader help

After updating to ICS firmware my phones bootloader wont let me downgrade to h-Boot1.17 from 1.2 and everytime i get a "MODEL INCORRECT" and even when I try to reflash ICS firmware still says "INCORRECT".....any help?
You need to complete the super cid step in the android dev section guide. That then allows you to flash any ruu.

RUU as a zip file? returning back to stock

hi
this zip file in this thread http://forum.xda-developers.com/showthread.php?t=2123337
was the latest version of the software i was running before i unlocked the bootloader and installed a custom rom
in the thread the zip is listed as an ruu how do i use this to get back to stock?
in the zip file is meta-info , system ,firmware.zip,fotaboot and skin_fota
That is not a RUU, its a OTA file. RUU is an executable (.exe) file.
An OTA will not return you back to stock, either. For instance, it will no return you to stock recovery (which RUU will do). Better off to find and run the appropriate RUU for your version (if one exists).

You can technically flash the recovery.img from the OTA and then flash the OTA through stock recovery though I can confirm that evenso, the phone is not returned to 100% stock. The htc splash screen and I'm sure other things do not get flashed. I have run an OTA a few times though and never had any problems.
RUU IS the best way to return to 100% stock though.
thanks for the ultra quick replies
i am really struggling to find an ruu for my phone
i am correct in that i cannot flash a lower ruu?
if i go supercid can i flash any ruu?

Based on this, it doesn't seem that there is an RUU for the HK Jellybean stock ROM.

If S-on, correct, you cannot flash a previous version RUU (usually hboot version check is what prevents this).
SuperCID will allow you to flash an RUU for another region, but still will not allow an RUU with previous version hboot to be installed (SuperCID bypasses carrier/region check, not version check). You also need to be really careful with SuperCID; since with SuperCID and S-on, some Jellybean RUUs will brick the device.
S-off bypasses all security checks, and will allow you to flash a previous RUU.

I'm unrooted, locked bootloader and on 9.30. Can I SBF back to an older verssion?

I know there isn't a root or unlock bootloader exploit for 9.30, but can I use RSD lite and SBF back to a rootable firmware?
no you cant.

2.20 RUU to 3.18 OTA, ok if unlocked?

ok so I have a ATT one x phone that I just RUUed to 2.20. I am successfully unlocked and rooted, twrp is installed and I am ready to flash a custom ROM. right now I am S-on.
Can I accept the OTA to 3.18 without consequence? should I S-off and then update? I would like the new firmware and radio and then just flash a custom jellybean ROM, or I can just do it manually afterward.
I have no problem just applying anew ROM but if I can get the newest radio/firmware first it would just save a few steps.
Don't take the OTA, you can't install an OTA on a modified device. Plus, even if it did work it would undo all the work you've done. The best way to update your firmware is via the 3.18 RUU, but you must get s-off first or you'll brick. So get s-off then run the RUU. Don't worry about relocking your bootloader, that isn't required. Once you've run the RUU just flash TWRP again and you'll be good to flash a ROM.
