[HTC Wildfire S] MiCeltic:
Going back isn't always easy and it's made more difficult because your nephew's phone is Tesco branded. Anyway, I got some sleep, and some rest so I looked over these referenced RUUs and ROMs. I pulled the, "ROM.zip" out of both the Tesco 1.37 and Europe 2.26 RUUs, unzipped the Eu2.26 and see that it would flash hboot 1.09.0099 and the filename says radio 7.57.39.10M. You already have those on your phone per the, fastboot getvar all info, so there's really no particular reason to flash the Eu2.26 RUU and all that hardware. I would suggest that you consider flashing Crossfire77's "3) it is perfectly stock rom,not even rooted.of course odexed." ROM referenced previously, and that you just quoted in your last post, as it is based on the Eu2.26. Just re-unlock your phone, do your wipes, put it on the SD card and flash it like any custom ROM. I'd then run the, fastboot getvar all for reference. Try Crossfire77's for awhile and see if it works for you. If not, wouldn't it be great if it changed your, "version-main: 2.26.1107.1" to 2.26.401.3 like the full Eu2.26 RUU then if you still had problems and needed to flash the full stock ROM, you could do something like below to get your Tesco region (HTC__052) in the ROM and flash it...do you think there's a problem with your radio or something?

Keep in mind there's always other options like the latter part of option 1., extract and flash from recovery the boot.img, system.img, and if you want the original recovery back, recovery.img; or, downgrading the hboot, etc. Remember successes, failures, or brickings are your responsibility because you make the decision, so look and think all this over. I might have gotten too far into this and confused myself ::haha::

Here are the details of adding your cid into the ROM...if at a later time you need/want to flash the full Eu2.26 RUU pull the, "ROM.zip" as in the previously posted link. I looked in the, "android-info.txt" files and it says:

modelid: PG7610000

cidnum: HTC__001

cidnum: HTC__N34

cidnum: HTC__203

cidnum: HTC__102

cidnum: HTC__405

cidnum: HTC__Y13

cidnum: HTC__A07

cidnum: HTC__304

cidnum: HTC__032

cidnum: HTC__016

cidnum: HTC__E11

mainver: 2.26.401.3

hbootpreupdate:13

DelCache: 1

In the Tesco1.37 ROM the, "android-info.txt" file says:

modelid: PG7610000

cidnum: HTC__052

hbootpreupdate:13

mainver: 1.37.1107.2

DelCache: 1

So, since your phone and the main-version in this RUU are 2.26 all you should have to do is take that, "HTC__052" (remember there's 2 underscores) and add it in the "android-info.txt" like this:

modelid: PG7610000

cidnum: HTC__052

cidnum: HTC__001

cidnum: HTC__N34

cidnum: HTC__203

cidnum: HTC__102

cidnum: HTC__405

cidnum: HTC__Y13

cidnum: HTC__A07

cidnum: HTC__304

cidnum: HTC__032

cidnum: HTC__016

cidnum: HTC__E11

mainver: 2.26.401.3

hbootpreupdate:13

DelCache: 1

Save it and add it into the ROM.zip and run it as discussed earlier, i.e., Relock the bootloader and rename the zip to, "PG76IMG.zip", put it on your SD card and boot into the bootloader...actually should run automagically or after a yes/no prompt. Keep in mind the possibility of an error if your main-version is still: 2.26.1107.1 but either way with the region HTC__052 added into the, "android-info.txt" file in the zip it should be OK because .401 is WWE and you can see above it has lots of other provider numbers associated. I'll add to take the, "PG76IMG.zip" off the SD card after all's done! ::yikes:: don't want to do that every time you boot! ! ! Hopefully though, Crossfire77's stock ROM will work and you won't need to do all this.

I've gotta post this or I'll keep editing it. I had another, "PFM" moment last night...my monitor just died. I tried everything to troubleshoot/fix, including unplugging everything and nothing worked. So I left it all unplugged overnight, plugged it this morning and, "PFM" it's working fine. I have to catch up on stuff now. If you haven't given your OneX to your nephew got yourself a One and tossed the WFS, post what you decide and end up doing or if you need more ideas.
