[SOLVED] Can't flash RUU's?

Sorry for creating a lot of help threads, but things just don't wanna work my way.
Yesterday I wanted to flash a RUU to see exactly how HTC does things and if it's easy or hard. Anyway. I come from a Galaxy S3 and if I wanted to go back to stock from any other rom, I simply flashed a stock rom tar with a program called Odin, but it doesn't seem to be as simple with HTC.
I downloaded a RUU for the Europe region as it seemed the most obvious thing to do, but my CID is Nordic (HTC__Y13). Here's how it went:
Being on a 4.2.2 custom rom:
I tried running the RUU when I was on a 4.2.2. custom rom (InsertCoin 2.0.2), and I fired up the RUU file and followed the instructions. Then it said my phone isn't supported and that I need another RUU file.
Being on a stock odexed 1.29 rom:
I then installed a stock 1.29 rom from Mike1986. and then fired up the RUU. I followed the instructions and it seems the flashing started. It sent me to the RUU mode (the HTC screen) and began the flashing process. It said it wiped the data and that it sent some signature keys, I think. Three minutes later, the RUU window disappeared. I could see the program was still running but the window disappeared. It quickly flashed for about half a second and I could see some text saying that my phone isn't supported, but why the hell did it commence the flashing?
I pulled the cable, long-pressed the power button and let it boot, it hadn't wiped a thing.
Let it be known that before I opened the RUU's, I made sure I was bootloader locked and S-ON (with the revone method).
Is it because I have the Nordic CID and I had a RUU for the European region? If so, I looked anywhere and everywhere for a Nordic RUU but there's none to be found.
Any help is appreciated.

You can only use an RUU which is the same or newer than the firmware on the phone, e.g. if your last official update was 1.29.401.13 you could only use an RUU that version or above UNLESS you're S-OFF, in which case you can use an older one if you have Super CID and a locked/relocked bootloader

So what you're saying, is:
If I acquire Super CID, then flash a Europe RUU and then set my CID back to what it originally was (or maybe even set it to HTC__001) and then reflash the RUU, and it'll work beautifully? I'm S-OFF, btw.

Where you S-Off or S-On when you ran the RUU?

S-ON with the bootloader locked. I wanted to see if it was possible.
I'm not really looking to revert to unrooted stock, at least not now. I just want to know that it's possible without too much work for when it would be necessary or when I want to try out unrooted stock again. It's always nice to have a fallback.

As far as I'm aware, you can only run a RUU that is relevant to you device whilst you are s-on and only one that is equal to or above the firmware that you are running.
The only way to return to official un-rooted stock is, again, to run a RUU for your device or install a completely stock nandroid backup of your device or one running the same version as yours.

OK, full example...
You originally get an unbranded One from the EU and you get the OTA to 1.29.401.13. From this point on, with an S-ON/Locked phone with CID HTC__001 you can ONLY flash an RUU which is 1.29.401.13 or higher. This will never change. If you get an RUU from a specific carrier you cannot flash it as it doesn't match your CID.
If you unlock the bootloader, but stay S-ON, you cannot flash an RUU at all - you HAVE to relock the bootloader first but you can still only flash an RUU matching your CID and is the same or newer than your current version.
If you S-OFF and change the CID to 11111111 you can flash ANY RUU you want, even those older than your current version, e.g. 1.28.401.7. You still have to have a locked/relocked bootloader but you can stay S-OFF and flash the RUU. As the only RUU available at the moment for the unbranded One is 1.28.401.7 it means you can flash that and then get the OTA updates in sequence to get to the latest version
Once back at the older version using the RUU you could change your CID back to HTC__001 if you wanted but I don't think it matters

Ah, thanks for the clarification! If I do this (Super CID plus flash the RUU), should I change back to the HTC__Y13 cid or change to something like HTC__001 to get the updates for the Europe region? I heard Europe gets OTA's faster than other regions.
One more thing, why does the bootloader have to be locked? Does the RUU check for this?

If you wish to get ota's you will need to have a cid which is relevant to the RUU you have run. Either of those cid's should work for a x.xx.401.x RUU. Not sure about the bootloader locking for an RUU.

The bootloader doesn't need to be locked to flash a RUU. A guy over at Swedroid flashed a Europe RUU (401 device) (after setting Super CID) coming from a carrier-branded One and the RUU did flash perfectly.
I would of course want OTA's, but the thing is, I heard Europe gets them faster than the Nordic region.

Not necessarily. As with the s3, releases seem pretty random from country to country in Europe. I had the one x with HTC__001 cid and was one of the last to be updated.
Sent from my Nexus 7 using xda premium

Locked the bootloader and went into fastboot and started the RUU. It is now flashing :victory:
After it's done, I will turn the CID back to HTC__Y13 and reflash the RUU.

I, personally, would relock the bootloader purely to cover yourself. As for CID, it's up to you. Using HTC__001 might not get it the second an OTA comes out but I'm sure you're patient enough to wait a few days

I just want back to stock for a few days. I'm a bit tired of custom roming yet I can't stay away from it!

I've done the same with my Nexus 4, and shall do the same with my One when I get it next month. I want S-OFF purely because the only RUU we have is an older than what I'll likely get on my phone. This way I can always go back to stock (unless a newer RUU leaks that is!)

How awfully peculiar, though. After I flashed to stock (the 1.28 something RUU), I got an update to 1.29.401.12. My brother, whom also have a One in the same region as I, has the 1.29.401.16 update (I am four decimals behind him ).
I thought I would get an update to .16, or am I just being too impatient?
I know I had .16 before custom roms though.

I read all, very useful conversation,saved me lot of time
Only a thing i havent understand
Im now S-OFF,unlocked with superCID ( runnind a branded italian rom with (now old)TIM__041(if i rememeber right)cid)
What i need to do to have a stock unbranded european RUU
Do i need to relock bootloader Before flashing or not matters?

[Q] Trying to get the latest OTA update

Hi, I'm s-off and CID 11111111 and I'm in Canada, I flashed this

What wrong here? can't I get the update this way?
Thank you...

at the very least, its because you have a custom recovery. Thats why the OTA failed

Where can I download stock recovery? and if i got it what i did should work in theory right?

If after you've flashed ruu, didn't flash anything .You already have stock recovery!
Other words ,after RUU you at the stock recovery.
What your MID?
"RUU_M7_UL_JB_50_HTC_Europe_1.28.401.7_Radio_4A.13. 3231.27_10.31.1131.05_release_310878_signed" seems for 0710000 MID.
More likely,the reason of fault OTA - you are unable to meet mid OTA update.

Oh, I see thank you for the help.. My MID is PN0712000

You are trying to flash the OTA to htc__y13 cid/0710000 mid on phone with 07120000 mid - it's a bad idea.
What to do?
1) You can change mid, but I strongly DO NOT advise - this is a dangerous procedure.
2) You can flash the RUU for your mid and just wait for the OTA update will come to you - it is good

My Origianl CID is BM___001, and got it s-off for ever

Unfortunately, I don't oriented to the North American operators,and I do not know what is BM .
And therefore can't advise the exact RUU
OK, let's go through the first way, under your current state change your mid to European
type:* fastboot oem writemid PN0710000
Stop stop! Before change mid type here your : fastboot getvar all

I did not find your BM RUU from here
http://forum.xda-developers.com/showthread.php?p=39588860
and here
http://www.androidfiles.org/ruu/?developer=M7
Only a nandroid backup ,but I think it is not full stock, at least a stock recovery is missing and I'm afraid something else.
Time you were already flashed by the European RUU, let will change MID to European. And you will be have completely European unbranded phone.
if you decide do it .. print here " fastboot getvar all" (without your imei) I'll check your current state.

But before downgrading hboot, check what RUU are available for ATT. I think there is a 3.xx.502.x RUU that works with hboot 1.55

yes that's the one and on a side note theirs a decrypted version RUU.zip of it that will work with your current MID and CID with a small alteration to the android-info.txt
http://www.htc1guru.com/dld/ruu-zip-m7_ul_jb43_sense50_mr_cingular_us_3-17-502-3-decrypted-zip/
Instructions for Flashing RUU Zip Files:
Download the RUU.zip file and place in your ADB/fastboot folder. I would recommend renaming the zip file to something simple like ruu.zip.
Boot your phone into the bootloader by holding the power and vol up/down buttons at the same time until you see the bootloader screen or if you have your phone booted you can use the ADB command:
adb reboot-bootloader
Now use these fastboot commands:
fastboot oem rebootRUU
Should see the Silver HTC logo. Now issue this command to flash your phone using the ruu.zip file:
fastboot flash zip ruu.zip
Now the first time you issue a command to flash firmware/ruu in fastboot it only prepares the flash. You have to issue the exact command again:
fastboot flash zip ruu.zip
The green status bar usually does not reach the 100% mark. When the output in the command window is complete, you can reboot:
fastboot reboot
**Notes about the RUU.zip method. You still need to have the proper CID for the RUU. You can run the RUU.zip with super CID, but you will have to lock your bootloader first. If you are running the RUU.zip as base to downgrade all your firmware because you are going to then going to restore a stock Nandroid so the RUU might not be made for your MID, so you may need to edit the android-info.txt inside the ruu.zip to include your MID or CID.

hboot 1.55 introduced an interesting patch, when going from S-Off to S-On, after a few reboots it comes back with "tamper detected - rebooting", and then TAMPERED is back in bootloader.
NB: i cannot confirm this to be 100% true, but i've seen more than a few posts that confirm, even after a full signed ruu etc etc etc, this has happened.
only way to avoid it was to go s-on before updating to 1.55 (hence my guide says to downgrade to lowest version)

[Q] Going back to Sense from GPE

Hi all.
Last week, after i soft bricked my phone (HTC ONE M7 EU with no carrier , bough directly from ) trying to update it to the latest version (i had mine unlocked and rooted to solve previous battery problems), i finally fixed it with the help of an user of this community
I have now an S-off HTC One GPE with 4.4.4 (via OTA update after flashing a RUU zip)
I kinda not like GPE and i think i should back to Sense .
Can anyone point me to the correct RUU thread and/or instructions or presequisites i shoult take account to do this process?
Thanks in advance

considering you are s-off,
very little, but even with s-off, you will first need to downgrade hboot to same or lower version than the signed ruu.exe/ruu.zip
on the other hand, a decrypted ruu.zip doesn't have that restriction

So my process will be...
1. Downgrade hboot to 1.44
2. Change back my cid to HTC__002 (when i flashed the RUU from the GPE i changed it to GOOGL001)
3. Flash the RUU zip
Is that right?

you don't have to go back to hboot 1.44
If your RUU is 4.xx flash a 3.xx firmware first
or 3.xx RUU a 3.xx or 2.xx firmware will work.
you may also need the MID change tool if you changed it also

The 1.28.401.7 is Jelly Bean it's equal to a 3.xx.xxx.x RUU
So the Firmware you would want is this http://xda7.androidrevolution.org/db_mirror/Firmware/HTC/HTC_One/401/2.24.401.8.zip

Htc One AT&T trying to upgrade to lollipop using official RUU - get error 155

Have a Htc One (AT&T, but unlocked) and it is running Android 4.4.2 . I see there is an update for lollipop in form of the RUU officially from HTC (7.23.502.9).
http://www.htc.com/us/support/htc-one-att/news/
I attempted to install it but get an error 155.
Using Windows 10.
Drivers are installed.
Tried several RUU's but with same result. Tried it on 2 laptops (both windows 10), have no accesss to windows 7 or windows xp at the moment to try anything else.
Attaching a screenshot of the bootloader screen of my phone.
Any help is appreciated.
Thank you,

Your phone need to be at least on hboot 1.57 (6.xx.502.x) to use a 7.xx.502.x RUU.
Since your phone is S-OFF you can esiliy update your firmware and flash the RUU.
Btw, are you still using the AT&T network ? If not, it would be the right time to flash a de-branded ruu version (like 7.19.401.51) to get rid of at&t's bloatware...

Thank you for your time and response. I will think about what RUU is best for me. I am currently on the T-Mobile network with this phone and so far there is no indicator that will change anytime soon. I will try and post my response.
Thank you again!

Unfortunately I am still hunting for an RUU that will bring the hboot to version 1.57. All the ones I tried either fail with error 155 or they leave me on the same version of hboot. Trouble finding an appropriate RUU... If you know where I can get one that will upgrade the hboot to 1.57 please guide me in the right direction.
Thank you!

You don't need to flash a RUU to update your hboot, just update your firmware (flash a firmware.zip) like this one. Make sure that your CID and MID are listed in the android-info.txt file, if not, edit the android-info.txt file so your CID and MID are listed (Better to use notepad++).
Code:
fastboot oem rebootRUU
fastboot flash zip firmware.zip
fastboot flash zip firmware.zip
fastboot reboot-bootloader
Then you can flash a 7.xx.xxx.x RUU (don't forget that your CID and MID must match the RUU you want to flash (You can easily change your CID and MID when S-OFF)

Thank you very much, I will attempt to do this and I will post my results once I had a chance to try it.
One more thing, isn't having a super CID an advantage?! Is 11111111 a super CID?!
Thank you!

Yes, supercid is 11111111 so your CID isn't a problem. Just make sure that your MID also match the ruu you want to use (or change it if needed). If you MID is still the original, it should be PN0712000 so you can either use an AT&T or Developer Edition RUU (x.xx.1540.x). Otherwise if you want to use the WWE version (x.xx.401.x) You'll have to change your MID to PN0710000.

It worked. For a moment the output in the command window seemed like it was giving errors (unfortunately it was very late and I did not copy the output) but in the end I realized it updated the hboot and I was able to flash a different RUU.
Thank you for all your help!
