[Tutorial] How to write IMEI to HTC using fastboot
(19-08-2018, 10:25 PM)X3non(19-08-2018, 08:43 AM)murch Aft first it seems to work (if I check imei using getvar it does show the changed imei, adfter having used the command fastboot oem writeimei), but as soon as I exit flashboot and boot the phone regularly, the IMEI gets changed back automatically... Any ideas why / how to fix this? thanks a lot!
is the IMEI of your device invalid?
(20-08-2018, 10:10 AM)murch No, I'm trying to restore my original IMEI.
I know it's very strange but it did change automatically somehow and phone that was working until 2 hours earlier (I was abroad on vacation, used the phone normally also with data roaming, made phone calls, etc..) as soon as I got back to my homecountry and switch off flight mode (I was really on an airplane) the same phone and sim card that worked perfectly both in my homecountry and abroad 'til 2 hourse earlier, suddenly stopped being able to register on my carrier's network due to "suspicious" IMEI (according to my carrier), so I checked my phone's imei with the imei written both on the back of the phone behind the battery and on the original phone's box - which I still have, and my phone's "current" imei has actually changed to a weird 35XX9500000017 instead of my original and correct: 35506XXXXX826X1 [Xs inserted by myself of course) . With all those zeros that Imei seems something artificial used perhaps by some dev while coding / developing roms to randomly assign imei to a device, I really don't know...
I've been using this phone with different carriers in different countries for years and never had any problem until some days ago....
Please help me out to fix this. It's like when I input the fastboot oem writeimei command and then reboot the phone, there's some kind of protection on bootloader (imei section?) that restores the previous imei / doesn't allow for actual permanent change...

try flashing stock rom first then s-off then root then retry restoring IMEI
see if that works
(21-08-2018, 10:22 AM)murch Thanks, so basically I should unroot the device / s-on and relock bootloader, flash stock rom (with RUU?) then re unlock bootloader / s-off and re-root the phone and retry the fastboot command oem writeimei ?
From what you suggesting you think there's something wrong with hboot / fastboot commands not working properly, correct? So you reckon there's no protection preventing imei from being changed (for instance on NV partitions / modemst1, modemst2, fsg)?
Again, thank you very much!

from what i suggested, you'll be able to eliminate causes i.e whether some form of protection or just an OS fluke

Any ideas on how to solve this / other methods to unlock bootloader beside HTCDev?
Thank you very much

(27-08-2018, 10:38 PM)murch I've managed to unlock bootloader (had to flash a firmware that had unlocked 1.27 hboot), then tried again command fastboot oem writeimei XXXXX (correct imei). At first seemed to have worked, but as soon as I rebooted phone and checked imei by dialing *#06#, still got the wrong imei.... Any advice on what to do?
Thanks

After writing IMEI in fastboot, did fastboot getvar imei reflect the new IMEI before you rebooted?
