Hi everyone, I in korea now and looking for a new phone. SKTelecom have HTC Desire, but i wonder if:
1)Can i flash custom roms on it, saving compability with SKTelecom (SKT doesnt use IMEI, also have sim-lock)
2)And most important, if it can be used in China with other carrier. (Be unlocked from SKT and hardware compatible with standard WCDMA2100, China Unicom)
After a lot of investigating in another thread we found the Korean HTC desires without IMEIs infact do, but they are not on the label and hidden in rom. It is accessible by going to the debug menu ( forgot it, hopefully another helpful member van provide it)
Regarding custom Roms, I think it should be possible to flash a custom Rom on that phone as long as you use unrevoked or the gold cars methods.
I expect you can and would need to to unlock (if they can get rid of all parts of the Rom that deal with imei they can get rid of the parts needed for unlocking.(HTC desire's in the UK on Orange have a quirk where you are unable to unlock until you install a custom or debranded Rom.))
Sent from my HTC Desire using XDA App
Thank you!
Well, another question: Is it possible to make 100% dump of SKT rom and flash it back? (Guarantee issues)
I have an A5_UL and I want to downgrade to ROM version just one point before it went to Lollipop. First of all, I can't find my carrier nor country/region on HTC's RUU Site, can I just flash an European RUU with HTC as a carrier? I do live in Europe but my carrier certainly isn't HTC. Also, which version was the stock ROM before it upgraded to Lollipop. I know it started with android 4.4.2. but I'm sure there were some updates in between that I don't want to miss.
Note: I am S-OFF
Thanks upfront!
Nobody?

There were several 4.4.2 updates. for most devices, the last one before Lollipop(2.34) would be 1.58. RUU is usually not available for most variants. you can root your phone and restore a Nandroid backup of 1.58 but you'll need to find such backup specific to your device here. If you're S-OFF thenyou wqon't be limited to certain CIDs/regions but you should still watch for MIDs

So if I'm S-OFF, I can flash the RUU for any carrier and region as long as I flash the Desire 816 ones? Also, on the HTC's site there is no mention of any carrier or model ID's so even if I determine the one for my phone it still wouldn't mean much when choosing a RUU to flash.

Mids are important; you may be able to install anything because you're S-off, but That's exactly the reason that you should be extra careful because there are no safety measures to prevent you from damaging your device. Devices with different Mids may have slightly different hardware/ antenna , so installing a different RUU may damage your device

I understand but I can't find any information related to MIDs on the HTC's site from where I intend to download the RUUs. How do I discern which one will work on my phone?

I think it has. If you hover over download links in the last column, you will see that file names begin with variant names.
I guess it would be easier to just find the most recent kitkat nandroid backup of A5_UL around the net, but I wouldn't know for sure as I haven't looked for it

Is the last part MID? Do I even need it? The download says it's for A5_UL and my phone is A5_UL. I'm pretty sure the minor differences between the phones are differentiated by UL, DUG, DWG (and so on...) so if I flash UL to UL, I should be okay? I found the nandroid backups for my phone but I prefer not to use someone's backup as a primary way of restoring the phone.

I don't know about the last part but generally, if it's A5_UL and you're S-off, then it's possible and it will be OK (fingers crossed); although I'm not sure if these files are really RUUs (more like kernels and other stuff for developers) and flashable. you can always try.
nandroid backup is a good idea; they're usually untouched, and you can always do advanced wipe and factory reset afterwards to revert them backup to original.
good luck anyways

Downgrade HTC A5-DWG India
Hello Experts...
I was looking for a tutorial to downgrade my HTC 816 Dual Sim [DWG India] from Lollipop 5.0.2 to Kitkat 4.4.4 as i was having issues with WiFi after restoring a Lollipop update via A5_DWG Lollipop TWRp Backup Indian Users
And i have located my v.4.4.4 MR file from HTCdev...
Can some one plz help me to install the downloaded MR file so that i can make my WiFi working and go back to KitKat version safely....
A step by step guide will be most welcomed as i m not an expert in this...
And my handset is now S-ON, ***TAMPERED***, ***UNLOCKED***

I'll probably go with the nandroid backup method because I really need something failsafe - this is still a new phone and I don't want a three month old paperweight. Regarding wiping data and cache, yes that is good but someone could still easly modify the system apk's before backing up. I'm not saying that method isn't valid, I just try to avoid it for security reasons. Also thanks for digging up that code list, it doesn't help me but it might help someone else.
And you, @chikkus5088, you can't downgrade by RUU unless you're S-OFF so just get a TWRP/CWM kitkat backup like said above for your model and you're good to go.

If you can find the rxact OTA or firmware for your device, I can guide you on how to fix your wifi problem in lollipop. otherwise, listen to CrashBandicootX and find a suitable Nandroid backup (CWM/TWRP)

I'd always do the wipe. Ofcourse, make a Nandroid backup beforehand, just in case.
Bad news for all, HTCDev doesn't distribute RUU's after all. Why does no company do this? Anyways - thank you @seekfind for taking the time to help us all. I'm about to flash the nandroid backup I've found on the net but before I do that, is there a way to backup my applications and data from the Lollipop version? I know Lollipop always runs ART so all of my apps that get backed up are already precompiled making them unusable with Dalvik VM - can I switch the stock HTC's Kitkat rom to ART or did they disable that?

Who has the USA version of the ZE551ML rooted that can extract the baseband (radio) and send it to me so I can flash it in my ZF2 CN version. I will sacrifice my ZF2 and see if that way we can get different LTE bands from different region phones. See the method below, I will need the Radio Partition as a radio.img file.

Hey thanks, I will appreciate it. Sorry I didn't answer back earlier. I am going in a trip and being super busy trying to get everything together. Apparently is not so obvious on the Zenfone 2 where the radio firmware reside. All mayor manufacturers have a separated partition for the radio, asus does not atleast not with an apparent name. The phone have around 18 to 20 partition. Chech this thread for what some people that are trying to backup the modem and EFS have found http://forum.xda-developers.com/zenfone2/general/investigation-efs-t3153154. The guide for dumping partitons is this one http://forum.xda-developers.com/showthread.php?t=2450045 I will appreciate if you help me out. I will contact you once I get back. thanks in advance.
I'm curious about the same. Bought a Zenfone 2 (551ml) in Taiwan only to find it doesn't work in europe :/
I wonder what the reason is segregating the frequencies, my galaxy s2 has been al over europe and asia without problems. Yet this brandspanking new phone won't even connect to the cellular network.
Hello, I want to downgrade my LG G4 (Software Version: H81220U) from Marshmallow to Lollipop so that I can root my phone. Could anybody guide me to achieve a downgrade AND a root? My carrier is Telus/Koodo in case it's relevant information.
Thank you in advance

first you need to nkow if tou can as in some models antirollback changes and makes it imposible to downgrade. so first make sure that antirollback versions they are if the same then you may if different then youll hard brick phone.
Hi @syphlect
Did you manage to downgrade it?
Have searched all the forums, did not find a way to root the LG G4 H1220u Koodo version.
let me know if you found any links
Use ...
Use ... LGUP - NEW ( https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803 ) to downgrade from MM to LP. You want H81210 for your Lollipop KDZ. Once you've done that, you can install a pre-rooted image (easier) or root your own extracted KDZ. Note: You will not be able to obtain root through any of the Root-Apps - check out the link in the next paragraph for the general how-to for the H812, if you have not already done so.
Refer to [Canadian Guide] - Complete Source for the LG G4 H812. Linux VM/Root/Tools&Files at: https://forum.xda-developers.com/g4/general/canadian-guide-complete-source-lg-g4-t3212449 for the how-to on rooting the H812.
Follow the Root ANY LG G4 Variant 100% Success Directives | Root Injection | Less Bricks (https://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586) ONLY for installing the rooted image and use the command for the H812 model in the 2nd post here: https://forum.xda-developers.com/g4/...ot-lg-t3164765 found in the following box: Command to Flash System.img (All Variants):
Once done, because you still will have a locked bootloader, you will not be able to install a regular version of a custom recovery or flash a custom rom (that may come eventually when efidroid is managed to be ported to the locked LG4's). However, you will be able to install a non-regular version of a custom recovery with TWRP-in-FisH that has been tested on the H812 and is working just fine with Version 3 Beta 4 and 5 (you can find those links in the later posts in that site): [LOCKED][G4][TWRP][UNOFFICIAL] TWRP-in-FIsH for all locked G4 devices at https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048

Koodo is on the ... Telus network. You can use Telus KDZ's (doesn't specifically have to be H81210Z and they seem to be available (check the Canadian Guide) - others have indicated you can use other Canadian providers (read the Canadian guide). I can't confirm this personally.
Use LGUP-NEW for sure as you are less likely to brick from what I understand if an anti-rollback provision has been put in on the latest firmware upgrade.

Read through everything carefully. You'll find everything you need if not in the OP, in the member posts. You cannot upgrade to MM and keep root and you cannot install any custom rom at this stage as the H812 has a locked bootloader that cannot be officially unlocked.
With steadfasterX's TWRP-in-FisH (https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048) you can install a customized version of TWRP recovery that will allow you to back up your complete phone.

You will find most of ... the questions you are asking in the Canadian Guide I provided the link to. Try the search function for the site posts
You are looking for an H81210 for Lollipop. I would suggest H81210N or higher for your rooted image as it has the latest Stagefright vulnerability security update. You can however use for your stock Lollipop image a lower version, e.g. H81210H before flashing your rooted image. The only caveat is that you may want to use Rogers/Fido firmware if that is your carrier, otherwise you will lose voLTE.
Again, I suggest you read through the posts, search for answers in the Canadian Guide. It's all been covered there.
Addendum: Koodo is on the Telus network.
