even if you flash the damn G6 KDZ on it, maybe you never get network to work, that phone is just a music player, a internet browser, vamera, etc etc, mobile network maybe never get working if you flash this.

you can try but, i am not 100 sure it will work, maybe you brick the phone and then you have a brick, so...
even more you didnt know what variant is more close to your device and things get worse then.

kindly help me to debrand my T-MOBILE HD2

Hello everyone!
i have one t-mobile branded firmware htc hd2 which i bought it from and uk based ebay seller..its unlock..and i can recieve and make calls..
but im not able to use internet on the phone bcos it has settings for t-mobile network..
and i also tried to upgrade it through htc website but whenever im trying it says these updates are not for this serial number...
kindly help me in debranding my phone so that i can use this in australia with full functions..thanks a lot in advance..
trust me that would be a great help from you.
If this is a UK T-Mob HD, then its a contract phone and seems strange that it is up for sale so soon. Unless it has been stolen - I don't think we should help with stolen phones, unless you're willing to gvie me the IMEI number so I can check here with T-Mob.

Im not exactly sure if you want help making your internet work with your sim, or if you want help taking the tmobile rom off and putting a stock or custom one on..
If you just want help with internet settings then download the attached file and install on your phone. Then run the connection setup program in the start menu, connections screen and it should set up your internet and mms settings for the network you select (if its available).
If you want to put a custom rom on your device then follow my flashing a leo rom for noobs link in my signature to install HardSPL and then you can flash any of the roms in the rom development section to take off the tmobile branding and give you whatever you want.

What network are you trying to use it with?
I'm not too sure if you can change the connection settings easy on the T-Mobile ROM, I'd recommend flashing with the HTC unbranded ROM and then you can just select your service provider and it all works sweet.

I work for T-mobile and the only way you can change these settings is indeed to change to HTC unbranded ROM or any other ROM of your choice.

You must have flashed one of the TMobile Test Roms during your travels, which has that splash screen on it. Custom Roms dont include a splash screen so it wont be overwritten when flashing other roms afterwards.
Download the attachment and unzip to a folder on your pc. Sync using your usb cable and run the included customruu.exe file to flash back the original htc splash screen.

My Optimus got messed up, please help me!

Hello I searched all over for something like what happened to me but i didn't find anything. I bought my LG gt540 in Italy, I tried to update at the android 2.1 with the LG software but at the end of the update my phone is loading, I can hear the sound of the phone loading but nothing shows up on the display. My screen is blue.
I tried to flash it again with the v20a, v20b with KDZ UPDT but nothing is solving the situation.
I live in the USA and they already told me that they don't provide any kind of support for this phone because is not sold in the USA.
What can I do?
PLEASE HELP ME because I really don't know what to do.
The phone boot in download mode and if I touch the screen seems to me working.
I tried the update with 1notebook win 7 32bits,1 with 7 64bits, 1 with XP pro (but modded version called ICE).
I'm trying to install win xp pro on a pc just to try again.
Can anybody give me an idea?
try to flash, and flash again on several roms. phone might to work these roms.
Can anybody give me a list of rom officials or not to try that should be compatible with my cell phone?
Thank you

Just want to share bout my experience... i forgot what my firmware ver was when my gt540 still in donut (android 1.6), but then the first eclair came (baltic rom v20b) then i applied it.
After awhile a rom with my country language came, but the version is v20a.. i tried to apply it, but always get error.i tried another rom (same ver v20a), and get Linux Kernel Panic.. dont know how to fix it (cant even go to download mode), brought it to lg service centre.. only took them 20 mins to fix that, and i look the firmware ver was v20b with my country language. So i guess the ver really matter..
Now im in froyo though

well, when you bring this kind of phones in a LG center they flash it with a box, not with the software we use...I did it like job for so many years. The problem is that here in the USA nobody has this boxes because little stores that fix phones or customer centers are not existing. The LG told me that they don't support it here in USA because they don't sell it here and then they have no idea about how to fix it. If I was in Italy I was fixing in 20 mins too but the thing is that the versions that for right now I tried...don't work, 20a,20b.
What other versions could I try?
I have some news. The phone works and I understood what that is.
When is loading the android, is showing nothing but the blue screen...no logo in the boot etc etc...
The phone will stay like that until the key lock is not kicking in putting the phone in standby...When that happen i have to push the power on like if I want to turn on the display to use the phone normally and...like magic...everything show up again.
What could that be? and how can i fix this?...seems to me the boot loader but I'm not sure.
Thank you
Hi,
Did you try reset to factory defaults now, while it's working?
If that is no answer, try this
Good luck!
that's exactly the way i flashed my phone but i can't solve the problem of the standby...I resetted everything but nothing seems to solve this little problem.
Hmmmm....
Maybe you should read and try this!
Good luck.
Please post the results! (if you fix your phone like this method)

Android 5.0.2 update problem

Hi Guys ! Ireally hope you can help me !!! I purchased a lg g2 d802 on a website in germany (where i live). I updated my phone to lolipop. the update process finished without problem. now when i turned the phone on and wanted to use it, the touch screen was not properly working making the phone unusable. i processed a hard reset with the power and volume buttons but it didn t fix the problem. I messaged lg germany, with the imei number they found out that the phone is actually a version for the asian market, thing that i didn t know when i purchased the phone. i tried to get in touch with the website that sold me the phone but i can't. i don t get any answer from them. I guess the problem with the phone is that it was not made to work with the european lolipop update. does any one know, how i could fix that ? i am still a beginner with android. But i can understand technical stuffs quiet good.

Yeah exactly ! I don't like to be cheated out
ok, i have another question : now i got another lg g2 on android 4.4.2, it was working perfectly, this time i made sure that it was an european variant before i process any update then i did update the phone and i had exactly the same problem like i had with the other phone. after the update is completed, the phone has touch screen problem. i read a lot of infos on internet and learned how to flash firmwares. i first flash my lg to android 5.0.2, it succeeded but still this screen problem, then i flashed it back to android 4.4.2 and still have this touch screen problem. i wonder now if it s not because i use windows 10 !!! could it be ??

Zenfone 5 Bootloader Freeze

Hey guys, i new here soh, i don't know if its allow to post thinghs that probably had another post about but here we go.
Sorry for asking this but i've searching for a solution for days and guess ? i don't found nothing clear to give me an answer.
Ok, i had my zenfone 5 for almost 2 years, than lately he start to lag and stuff, soh i decide to change de rom. I unlock the bootloader and install the CM 13.1, the first hour seems to looks good, but some minutes after the phone just freeze and reboot, than i try another roms, RR( many Builds), the problem still going =/, now i'm using the Leopard black, and guess ? Yes the freeze still going.
after read like an animal for hours and don't find any clear information about this, i went here, and my question is: First, can i use any rom that its not the stock rom whit xposed and root, and berfore that lock the bootloader ? or its real necessary ?
Second, this freeze problem have a real solution?
Third: If all that i answer is no, some advice ? because i really don't want to use the stock rom...
Thanks Guys, and sorry for my bad english...
Sorry there is no solution for screen freeze issue as zf5 have different types of motherboard. You won't be able to boot(usb sign) if you lock the bootloader and have a custom rom or stock rom with custom kernel.
As I'm also facing the same issue my advice is flash stock rom (.540 kitkat is good as battery backup is nice) and lock the bootloader.

It doesn't make sense friend... i don't think that is something related to the batery....
i forget to reply before, i had open the phone to verify that possibility to had some kind of hardware problem, but no, seems to be all fine.
Soh, i back to the stock rom BUT, the DANM FREEZES still going... of corse they happen less often but still happening, that link you post here hpgramani, it do not work, and i search and found an tutorial to get back to stock rom, i made it, block the bootloader but as i said the problem still happen.

Hey there, if you are still facing freezing issues and have install stock rom then your device's bootloader is not properly relocked. I also faced same issues but after re-lock my zf5 is working fine... I will be needing following details so as to assist you further...
1. Current android version with firmware no. like .540
2. Fastboot version, to open fastboot type
adb reboot bootloader
Few months ago I was also planning to buy a new phone like you due to freezing issue... But I relocked the bootloader and now my zf5 is working fine, so I won't recommended you to buy a new phone if you are able to use zf5 more.
As buying a phone with major technological change is highly recommended but the phones available now and zf5 do not differ majorly.
But still if you need to buy a new phone(which I don't think is necessary) reply with following details
1. Your country
2. Your budget
3. Your typical usage

LGUP - now no radio - how do I fix it

Hi I followed lots of guides for the new Oreo update as it wasn't downloading automatically.
Got latest KDZ from here:
https://lg-firmwares.com/lg-vs995-firmwares/firmwares/
Flashed it with LGUP - now I have no phone radio - though wifi and bluetooth are working.
Any idea how I can fix this ?
Did I use the right version of LG UP ? I have tried downgrading KDZs but these also dont have working radios ?
Any idea how I can fix this ?
Thanks,
Rob
Could this be because my phone is VS995S
- when I check IMEI.
Rom I have installed is VS995
I have tried to install others with LGUP - but downgrades dont seem to work.
Ideas ? Anyone have an S qho can share a ROM ?
Anyone?
I don't think the S means anything special regarding firmware. I believe that just means the phone is the silver Verizon version.
Someone correct me if I'm wrong...

what comes up when you check IMEI, *#06#? is it correct?

It says can't find your current country.
What does this mean ?
If I go into settings the IMEI is correct.
I suspect problem might be as I am in the UK and this phone was obtained from an e-bay seller in Asia I think they flashed something strange which is why it wouldnt update to oreo by itself and why the standard kdz broke it.
Still would like to fix it so it works as a phone again.
i95swervin said:
They probably modified the partitions a bit. My guess is they used a modem from another carrier to get it working.
My advise is for you to downgrade back to nougat and see if the problem persists.
Using a carrier branded usa phone outside of its network brings it's own problems if your carrier doesnt support the proper bands needed.

I tried that, and the problem does persist.
