Hello
My device is bricked on bootloader, and I've tried all the ROM that can be me shipped ROM and not worked.
Then I read in a post in this forum that could be a damaged CID sector. And it could be restored....if I have a backup, I don't have it.
Also the post says that it can be re-calculated from IMEI, but my ebay vendor removed the IMEI stick, then I haven't.
I have the posibility of Use an CID obtained from another device, but if it depends of IMEI, can be a problem with mine??
Know anybody a solution for this?? thank you!!
Im in a rush so im going to make this quick, I tried to root my htc one m8 and it got suck in a boot loop. I then made the foolish mistake, of wiping the whole thing after getting into TWRP. So now im pretty sure there's no longer an OS on it. It's S-on and unlocked. Help?
If you phone was on Marshmallow, your mistake was probably using an old version of SuperSU (which was not updated to root MM). Bootloop or no boot is a common result of this.
You can restore the OS by finding the appropriate (for your CID) stock TWRP backup from the collection, and restoring it. Needed files and instructions here: http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
Or alternately, if an RUU exists for your version, relock the bootloader and RUU back to stock.
If you need more help on any of this (such as determining what version), when you have more time do fastboot getvar all, and post the results (delete IMEI and serial number before posting).
I bought my HTC one (m8 ) last week and have been trying to upgrade from android 4.4.3 kitkat using OTA but it says that my phone is up to date, which I know is not right. I tried to do it manually by downloading some zips from htcdev which didn't work. The one which came closest to working gave an error after verifying the package saying that it does not detect 4.4.4. I want to update to lollipop and would really appreciate if you told me which zip exactly I need to do that coming from 4.4.3. My imei is 352628060356880, my software number is 2.22.401.5. Boot loader locked, (S-Off), stock recovery.
You should bump your other thread, not start a new one.
First .. delete that imei no., never post them on open forum.
Second .. post fastboot getvar all result without serial & imei no. This will help people to identify your problem to help you.

Hi guys, I am writing this from Bogota Colombia, My problem as mentioned before its that I cant update my phone cuus I bought it here in Bogota. I have spoken with customer service for Latam and they told me I have one HTC One M9 from sprint. My phone have the S-OFF and its locked. They tell me that I have to restore the security back ON and then I may download a RUU from sprint to be able to update it. But that its something I dont really want to do, as I dont want to set the S back ON nor do I want to update from Sprint. Anyone know of an international ruu I can use, or perhaps one for South America?
I read that i have to root my phone to be able to download some RUU that I can use here but to be able to do that I have to unlock the loadboot I have the unlocktoken from HTCDev but before I use it I want to ask you guys for advice as what should I do. I read that its a good idea to back up the EFS file (for obvious reasons) but not sure how to do it.
Here in Bogota I haven`t found anyone able to help me.
Thanks for any help and please dont mind any spell and grama errors.

You can keep S-OFF. There is no need to revert to S-ON since RUUs and OTAs don't check the security status of the phone. Either download the latest 651 RUU from HTC and use the *.exe file or head to the ReadMe thread, extract the *.zip from the *.exe and flash it via the SD card method that is described in that thread.
Be aware that you have no choice when it comes to picking a RUU. Sprint is a CDMA carrier and the CDMA variants of the M9 have a different partition layout than the GSM versions. You can't even flash other CDMA RUUs (e.g. from Verizon) without damaging your phone.

Thanks for the advice, I will download the RUU and see if it works, but one question what should I do to be able to recover my phone in case anything goes wrong? What would you suggest to use for back up my phone? i mean the efs files so I dont lose my IMEI and other data? thanks
You don't need to unlock your bootloader or root your phone for being able to flash a RUU. And to be honest, I never had to backup any efs files. That might be necessary for other Android devices but not for HTC ones.
Edit: Oh, and be aware that a RUU will erase all personal data on your phone. So backup important messages, contacts, pictures, etc...

Just to let you know that it worked pretty well, I have now one update HTC One M9 thanks to you! .
Can you please provide me with a link for a stock rom image of the verizon prepaid model because I have looked everywhere and cannot find it. I am running latest TWRP and bootloader is unlocked but also I will add that big country RUU is not flashing. I get an error 219, etc please help thank you
Also, when HTC sync attemps to repair my phone, it says that it cannot locate any software so that's out of the question.
Can you please tell me how you originally unlock the bootloader and install TWRP? Or provide a link to the instructions you followed?
