Just unlocked G2 (tmobile) "No service"

I just unlocked a brand new HTC G2 Tmobile phone. I used my sim card thats been active for years, Its Cincinnati Bell Wireless prepaid. Should work fine, but now its saying "No Service" and wont make calls/texts? Can anyone help plz?

Did you use gfree to unlock it? Worked fine for me. Try going into settings and manually searching for network, and restart 2-3 rimes. Worked for me.

No i went thru a service. it was unlockthatphone dot com
ill try that tho....

Well there's no need to.
And I dont want to be the one to tell you, but you might not be able to get service again, even with a T-Mo card. I've read that a lot of people had that problem with the unlock codes.

Well i couldnt figure out how to unlock it. Looked for hours and the guides here were so confusing id rather pay 30.00
How do i figure out if it will ever work again or not?
Someone mentioned I wireless might be CDMA and tmobile was not? Any clue how to check this?

As long as the carrier uses sim cards it's a GSM carrier (99% of the time, I know Verizon Global phones use simcards too.) if that's what you meant.
And for your question try some searching. I never bothered to find/read up on that since I unlocked it without a hitch.

I called the guy back that unlocked it for me, and he states "its impossible for an unlock code to damage 'ware in the phone, the guys on xda dont know what theyre talking about" and that he will work with me to fix this, he says hes pretty sure its my Baseband Version which is:
Baseband version 12.22.60.09bU_26.02.01.15_M2
Any thoughts on these?

Also this is from the HTC forums: http://community.htc.com/na/htc-forums/android/f/99/p/7564/33750.aspx

Actually I've unlocked my phone with an unlock code that Tmobile gave me. Customer Service said you just have to be paid up to date to get an unlock from them.
It may just be that the G2 is on a different carrier band than the carrier you were hoping to use.
Unfortunately, the onus is on you to look it up, I wouldn't expect the customer service for your company to know if your phone will work on their network or not.

so whats the deal ... If I unlock my G2 with a unlock code from TMobile; so I can use it when I head the Philippines on vacation ... I wont be able to get service even with Tmobile ???

There are reports of unlock codes not properly working on the phone all over the place. After entering in the unlock code, some phones simply cannot find a network no matter what SIM is inserted (even one that might have been working before). I met one dealer who said the same thing as your guy (unlock codes can't do that to a phone and people on the internet are stupid), so I had him try inputting in the code himself---the phone became messed up and all he could do was apologize. Some phones work fine though.
You can fix this weird state by running gfree to get subsidy unlock (there are at least two really long threads explaining this). Check out the wiki for instructions on how to do this.

Your phone unlock guy just wanted to get his $30. He knows full well that the carrier-unlock function in HTC VISION is ***DEFECTIVE***.
Problem is that the eMMC chip on the phone is write protected, so the unlock needs to be relayed through to a second mechanism and applied AFTER REBOOT, but it gets corrupted and instead of writing "0000" into the specified location on the eMMC chip, it will in some cases write it ***ENCRYPTED*** -- some function of your unlock code. Ends up being locked to a (most likely non-existent) random carrier, and the unlock code will no longer apply.
Once it has been damaged like this, the ONLY way to fix it is by running "gfree" on it, which would have unlocked you SAFELY and FOR FREE to begin with.
Find the button at the top of the page labeled "wiki" and find HTC VISION in there, and FOLLOW THE INSTRUCTIONS! This will cure your phone.

Wow Android is alot more extensive than windows phone. I'll try th e gfree but I really dont have that much experience on this phone. I barely temp rooted and overclocked this to 1427mHz. And barely reading all the perm root and s-off threads right now... I hope I can do it to mine and my wifes phone without messing something up. I tried abd and I cant seem to get it to work right. When I tried temp rooting. Can I do gfree without a computer can I do everything on the phone without abd???

Well for carrier unlocking, I think you can only do it with adb, but what do I know.

Ok so the one is carrier locked or whatever. I need adb to unlock it? and gfree to unlock my unmessed with one. Where do i find these programs and instructions to use them. Im PC literate but cell phone retarded. thanks in advance! I dont wanna pay to unlock these.....

Ok ive done a little more research. I have the JDK and the SDK kits installed. Im preparing to use GFREE. But now im stuck. my SDK MANAGER says the following error when i try to boot it up.
Failed to execute tools/android.bat:
The system cannot find the file specified
What am i doing wrong? im trying but its a slow process.

Navigate to the tools folder and see if there is a file inside called adb.exe. If so, download and unzip both the temp and perm gfree zip files from the wiki into that folder. You should be ready to go. When you connect your phone to the computer via usb be sure that you have the usb debugging checked (on).

Im so lost. the company is willing to refund the amount i spend to unlock the phones, so im just gonna have it done that way. Will the one with the locked carrier be able to be unlocked by a professional?

I got the temp loaded, the ADB loaded, the tools loaded. But this is what comes up

Ok guys. Im desperate. Here is what Id be willing to do.
Im offering $20 to whomever can help me. Heres what I need.
I have 2x HTC G2 That need the FULL UNLOCK. Not the code, THE UNLOCK.
Im told its done thru this GFREE program. I am NOT smart enough to figure this out after days if trying. If someone can do the following thing for me, Ill donate that money straight to your paypal account.
-Send me a ZIP file with ALL THE NECESSDARY folders, with ALL THE NECESSARY files already placed in them, I plug in USB unlock phones, u get paid.
(I need ADK files, JDK files, all gfree files, EVEYRTHING i know itll be a big zip, but im payin so i dont mind)
I am unable to figure out these files, I am either installing the SDK files wrong or something, but I just need the files ALREADY placed in a file and just use them since im too stupid to do so desite reading many guides. Sorry ive tried. Now i just wanna use my phones.

[Q] Is my i927 partly-unlocked? (wanna update to ICS, hence asking)

Well, first things first...
I am a noob, and this is the first time I am using an android phone (moving from the Nokia N97 and Nokia C6). So please be patient (and tolerant).
The dealer I got this phone from wasnt sure if it was soft-unlocked (the ones which get locked if you update OS) or otherwise, and he most certainly didnt have (or give me) the unlock code.
The phone has been a delight for the past 3 months, and I love the the stunned look on the faces of everyone around, when I slide open the keyboard!! However, after doing a google search I discovered that there's an ICS update for the i927. And that has resulted in me googling to find out the likelyhood that my phone will re-lock to ATT.
To my surprise (or inability), I couldnt find a definite answer/guide as to what users of unlocked i927s, who do not have the unlock code, should do exactly, to "safely" update to ICS.
I have downloaded most of the tools (Odin 3.07, EFS 2.0.7 and the "I927UCLJ3_I927ATTLJ3_ATT" stock from samfirmware). And I had KIES and the drivers installed from day 1.
But the problem is that I dont have a road-map. Or a troubleshooting guide, in case I encounter unanticipated errors/crashes.
The other thing is uncertainty about the phone getting "re-locked". Some mobile repair guys say I should flash the update with my eyes closed (it wont re-lock to ATT, they say). However, the other side disuades me, and I have yet to find an across-the-counter shop which will give me an unlock code.
Of course, I think I can live without the update if I have to. But, I was hoping for a bit of help (or a step-by-step or link-by-link guide).
The other thing I want to know is whether flashing the ATT ICS update can also corrupt my IMEI details (and hence the need to back up with EFS)??
Finally, I would like mention that my phone is an un-rooted i927 (ATT) running Android 2.3.6.
Any help would be really be appreciated.

Not sure what to make of this..
The lack of replies has made me (even more) doubtful if a noob like me would be able to update my i927. I hope someone can tell me if my i927 is "updateable" or is the ICS update preferably for only the "authentic" i927 handsets??

If you have a SIM card from something not using the AT&T network, put it in. That will tell you if your phone is SIM unlocked or not (I think that's what you're asking).
In theory, applying the ICS update may re-lock your phone; it depends on how it was SIM unlocked in the first place.
My recommendation is:
1) Update to ICS (it's worlds better than GB)
2) If the phone re-locks to AT&T, then just buy and unlock code for a few dollars

I am already using a local SIM card on the phone (Airtel) since the day I bought the phone. All the features are working on the phone, except the WiFi tethering, which is also the biggest reason for my doubts (and reluctance) about flashing the ICS update. The WiFi tethering feature does not recognise my Airtel data connection (2G), making me to believe some features are still AT&T specific (like the ringtones feature).
The other thing is, re-locking is a significant concern, but its not the biggest concern (for me). Since I first visited the "Captivate Glide" section on this forum, I have read about problems like the IMEI number (or other important phone data) corrupting, bricking my phone (which I know no one in the world can guarantee against), or the phone getting stuck in the start up mode (read it somewhere here, although I dont know if it was an OS update related failure).
Anyways, I hope that clears up the current status of my i927, and thanks for replying.

A bit more help please...
I know I asking basic noob questions about updating, but I was hoping for a bit more guidance actually...
Like what do I do with the I927UCLJ3_I927ATTLJ3_ATT.zip file?? Do I unzip it, or just copy it the phone memory and reboot into Odin??
The other thing is I started the EFS app on my PC and connected my phone to it, but the IMEI and other numbers are just all 0s. So, I am thinking, I did something wrong there as well...
I am well aware that no one in the world can guarantee against bricking a phone. I just want to have a proper guide on how to update, so that I have the best odds possible

1. It seems you're trying to upgrade your Glide via Odin. Unzip the zip, get all the files, put them in Odin folder (NOT the SD card, Odin is a PC-based tool) in the forums to proceed.
EDIT: Google is man's best friend. This is the Odin guide I followed when just a week ago I'm still new to my Glide: http://androidromupdate.com/2012/11/10/i927uclj3-new-ics-4-0-4-for-samsung-sgh-i927-captivate-glide/
2. Your EFS may already be dead Or I don't know, never used that tool before.
Sent from Samsung Captivate Glide @ I927UCLJ3

Okay I'll still advice you use the efs tool to. Back up your efs foder,then put your phone in download mode, using Odin flash the stock ICS ROM when its through flash any of the recovery through Odin again then allow the phone to reboot. you can now flash any of the ROMs I prefer the lite ROM anyways.
Good luck.

Unlocking the Bootloader

Hi all,
As usual I realized problems later then I made a purchase and own a SEA version of LG G4 815, after spending couple of days with the official unlock site I figured out few things and realized I can not unlock this phone by myself. Originally even the adb and fastboot were not working for me, finally I used minimal ADB and fastboot and manage to get the device ID but this time the LG said my phone is not suitable for unlocking.
So my question is how different are the official "unlock.bin" files are? Is there any way to analyze these files and see what is different for each device and possibly make custom bin files for the unfortunate devices. Possibly someone already thought about this and there is an obvious problem with it that I can not see but if it is possible to change the unlock.bin and customize it, I might still have a chance to unlock it.
Thanks in advance for all that can help.

I guess unblock.bin contains unique device identifiers such as IMEI. Encrypted.
It would take decrypting, replacing IMEI, and encrypting again. Using a private key we don't have.

That is probably why we dont have this around. Oh well I will wait for a while but already start thinking to sell this phone. Should have gone with the HTC

By the way cant we use the bin files with known IMEIs to figure out the encryption?

JTAG G4?

Alright, let me preface this with a few things... I am FAR from new to android, rooting, linux, exploits, or almost anything embedded (UART, JTAG, SPI, I2C, etc...). I am by no means a guru though...
I am attempting to root this device; it is an unlocked LG G4 US Cellular branded, MM 6.0 lgus991 22a rollback 2, and I am so far at a total impasse... I'll explain my situation.
No fastboot.
Bootloader is locked, and I cannot unlock it. If I try and check "Enable oem unlock" it unchecks itself, and reading through the dmesg it references a file stating two errors; one for lack of permissions, and another for no file(same filename though; likely trying to create the file, being denied, then trying to edit a non-existing file). I forget the exact file name but I have the name of it saved somewhere(persis1234 or something like that, I just don't remember the exact path, I can post it later if it makes a difference).
I have had minor success with the dirtycow exploit, but mostly just replacing files and nothing getting anywhere, or the phone quickly reboots if I replace certain system files(ifconfig, toybox, toolbox, etc...) When it works,it says I have root, but it is VERY limited due to selinux, and the context. Also unable to get a root shell open.
Selinux is protected and I haven't been able to find a way to make it permissive as of yet. Past attempts of editing the recovery or init have resulted in "secure boot error 1003"; phone reboots, and then still stock...
If I grenade this thing, I will only slightly give a f**k. I am not above pulling this thing apart and trying to JTAG my way in if I need to, as it is not my only device. Which seems to me to be the only way at the moment aside from finding another kernel exploit like dirtycow or rowhammer... Unless someone else has another idea, but for now I am going to pursue the JTAG route.
Would something that I already own like a buspirate, RPI, or Arduino Mega, be enough or would I need something like a busblaster? I just don't want to spend more than I need to. I'd rather spend the money on a new phone than something like a medusa pro or something like that.
Any help is appreciated

Why not to flash TOT and then proceed with unlock through lg unlock tool? Maybe it fix the fastboot issue.

I am new to LG devices so perhaps this is a bit different(had mostly Samsung or HTC). But from what I can find, that won't help unless it's pre-rooted or my bootloader is unlocked. And I am unable to find a pre-rooted TOT. Unless I am just completely missing something here...
I am not trying to go to stock, the device is already stock and functions mostly alright(aside from the inability to add a Verizon APN, so I'm stuck with 3g). But also attempting to have a bit of a failsafe if I wanton flash something I shouldn't have and still have a recovery option. Which is why I brought up the JTAG option, as I'm sure I would use it in more than just this device.

Not sure why you are attempting to reinvent the wheel with a device that has been out for 2 years....
LG devices are very different from Samsung and HTC. You should read up on the LGUP tool to flash .kdz and .tot file to put the device as close to stock as possible before any further attempts.
Could also look at entering hidden menu options via the dialer in order to select/modify apn settings.
TWRPinFish can be found here in the development section. Will likely be your only option if you cannot fully unlock the bootloader.
Since the Tmo and ATT/international versions allowed bootloader unlock, other variants didn't see as much support. Was easy for us... Sorry to say(for you).
Wish ya the best of luck though

Just a quick remark could jtag be used in such a way to make the boolloader thinks it is something else and maybe trick it in to doing something?????

I don't really see this as reinventing the wheel as right now there is no root for this device, I am looking for a way to do it though. Which is why I was asking about JTAG/eMMc programming as a viable option to do this, especially if I may have a few borked flash attempts, it would be a nice fail-safe.
Most dialer codes do not work, and the few that do, pop up a menu saying "This program does not work on your phone"; even though I can see some info behind the toast, I cannot scroll and as soon as I click ok, it closes.
TWRPinFIsH is a no-go, need to be rooted and be able to disable SELinux, neither of which I can do.

The name of the file that stores the "oem unlock" seems to be /dev/block/platform/soc.0/f9824900.sdhci/by-name/persis1234
Would someone that is able to oem unlock be able to tell me what the contents of that file are?

Unrooting S20 Plus

Hi all
Hope this is the correct area...
My hubby bought me a S20 plus for my birthday through a local dealer.
I noticed a few issues like not being able to use biometrics or install certain apps.
I've since found out the phone has been rooted.
I've tried to do a factory reset, but this hasn't helped.
I've downloaded root checker and it confirms the phone is rooted. I've downloaded SuperSU yet is won't work as ver 2.82 claims it's for an older Version of Android.
I've downloaded solid explorer to delete the root access files such as Busybox and SU however I cannot find these files in the system folder or the system/bin folder.
Can anyone advise on how I can unroot my phone? I am unable to install certain needed apps due to this.
Phone details below. Sorry am unable to upload pics.
UI Version = 1
Android Version = 10
Let me know if other info is needed.
I've even tried calling the Samsung Center and they are unable to assist...
Thanks all

You will need to get hold of the stock firmware from somewhere like Sammobile and flash back to stock using ODIN. There's tons of guides knocking about on here for the step by step. The damage is done though as far as any Knox related features go, it's like a fuse that blows when you root and you can never fix that.
Having said that, biometrics should have never been affected by rooting so that's a bit unusual. Flash stock and set up from scratch then go from there, could be faulty also

Thanks for the guidance Dave. I'll search the forums for the steps.
For clarity, when I say biometrics didn't work, it works allow me to record etc, but when I tried to enable it, like on my banking app, it wouldn't allow me. This is how I eventually figured out my phone was rooted. While I know the benefits of being rooted, a normal everyday user like myself, certainly won't benefit from it.
I've had a Samsung my entire life, and always saw the secured by knox logo... When you say damage has been done, does this mean that all my security in the device, such as my banking details etc, may be compromised?
Jees. I hope not. As this would really freak me out...

Ok so Finding the firmware wasn't to difficult. Sanmobile quite easy to navigate.
Just a query please... My phone base band version lists g985fxxu1atb2 however the closest I could find to this is G985FXXU1ATBM
Is this ok or does it have to be the exact same description?
Shoo. Lol. Really hope I'm going to be able to get this right **insert nervous smile emoticon here**

The last letters are the region/operator of the Rom. Not necessarily has to be the exact description, the really important are the first that indicate model number.

Ok. So have downloaded Odin and am busy downloading the flash firmware.
May I please be so bold as to ask someone on here to please share a link tot he step by step guide that I will need to follow in order to flash my phone back to the original boot thingie :silly::silly::silly:
I have tried to search but seem to only come up with a nexus thread with no mention of Odin.
~Sorry to ask, but little overwhelmed LOL and want to make sure I do this properly and not screw up my phone.
REAL noob here, so apologies if I come across lazy and getting others to do the work, but am really grateful for the help.
Maybe I'm searching incorrectly???

I found this somehow....

**fingers crossed**

Can you unlock your phone with biometrics? Im guessing only the banking apps don't work because it's rooted. If i remember correctly most banking apps and maybe Google pay(not sure about that) stop working after rooting because the phone is "compromised" and it's not safe. You have to hide your root status from these apps and they will work properly then. Maybe someone else can help you with that because i do not remember how to do it.

Hi Marto
Yes, biometrics does work, although not really good. But that's probably due to the hectic screen protector.
Correctly so, it's mostly the banking / payment apps that won't work, and I can't check or download any software updates... Although I belive this can also be done manually....
But wow, there's an app that hides the root status? That might be a whole lot easier than re flashing. Truthfully I'm Sh!tting myself at the thought of attempting this ????

if the phone was bought as new, go back to the dealer and demand a new one that is not rooted.
could also be that your husband rooted the phone and installed software that keep tabs on what you do.
