Picking up a Droid 2 Global today in hopes of doing the Band unlock hack.
I understand it must be on Froyo to do this, and I am buying from a random/normal guy on Craigslist. In the off chance he upgraded to Gingerbread, could it be reverted to stock Froyo for the hack? I wanna put Hexen on it eventually.
Also, we went back and forth for a while, and he finally told me Verizon gave him the unlock code.
How do I "use" the unlock code and how can I tell if it's working or not?
So basically, it's...
- Buy Droid 2 Global
- Unlock Code
- Make sure its on Froyo and do the band unlock
- Flash Hexen
Am I missing anything? Thanks a lot!
Right.
You can still flash back form 2.3 to 2.2
Just bear in mind the "Unlock" step may prove to be hard to get. Given the fact you live in US, it is likely you could get "a hand" from a friend of yours on Verizon to get it unlocked. Just in case online unlockers can't.
Also - 2.4.xxx firmwares (Froyo) are known to have issues with HSPA connectivity - so called 'radio resets', in other words - be ready for not very fluent experience with this phone.
Personally I'd advise against going this way. Get yourself a Desire Z - much better modding capabilities and no hassle with unlocking/using it on any GSM network anywhere worldwide..
Wanted to make new thread to ensure responses, but don't wanna clutter XDA either so here goes. I'm buying a Droid 2 Global soon for my bro and wanna use with AT&T, so I have some questions
1. Does it matter what SBF or version is on it? I'm under the impression that it can all be flashed to the correct ones that I want to use.
2. Seller does not have unlock code, but he is a Verizon customer (just got iPhone 4S) and has assured me that he will get unlock code with me at meetup.
So basically, how do I reach Verizon/get unlock code (I think I can call 611 with HIS iPhone)? And how do I input it? And how do I know when its complete?
And anyone have a simple guide on how to do the process of flashing and applying the hack? I know its a search away so links would be nice (on mobile)
Thanks a lot XDA

if im unlocked, on 4.5.608 and N_01.48.00R
will the HSPA still suck?
I dont have an ATT sim right now but did the flashing, etc in case I ever did...
To get the unlock code from VZW, the phone needs to be on a Verizon line of service, and the account must be in good standing for the past 6 months.
As for firmware versions, you need 2.4.29 as the base. I'm not quite sure if it's possible to update to any other version leaving the baseband intact. 2.4.330 won't work.
And yes, HSPA will most probably still suck because it's a problem with the baseband firmware.
I followed
http://rootzwiki.com/topic/8326-d2g-gingerbread-hack-for-us-band-unlockers/
to leave the baseband but move forward for the overall rom.
I guess i'll need to get an att sim for the fun of trying out the 'bad' HSPA
I know it basically worked because I could use an available tmobile sim for a basic phone test - no att test as of yet.
Just an FYI. When I had an ATT SIM for testing I regularly pulled 6-7 Mbits tethering on it despite the so called "bad HSPDA+" radio performance of the original firmware versions.
This was freind's mother's SIM who had passed away and was an old basic feature phone plan that I added a 15/month unlimited data feature to when I borrowed it for a few months.
I used it primarily for tethering and testing various radio builds etc. when we were first working on it.
The low bars is a feature of the VZW Global phone configuration and not an actual signal issue.
The radio performance of networks outside the US may vary greatly from user reports and I have no experience with international use, but on ATT the GSM/HSPDA+ performance was generally excellent or at least quite useable.
Hi,
I'm actually not new to XDA, I 've been a member for about 3 years and used to screw with my old broken HTC G1 all kinds of ways. So ignore the newbie status, I forgot all the old login info and had to re-roll.
Anyway, so now I have a sweet shiny Droid 2 Global that I bought off a ebay for a very nice $149 buy it now in used but excellent condition.
It was listed as unlocked and obviously indeed is because I am running it on Tmobile with a tmob simcard in Dallas, tx. So, I can make calls, internet works and is ok but only on edge (2G), signal is generally pretty good overall.
My questions (after days of searching and reading up, don't tell me to search) Are these:
1. Am I already band unlocked? I can already use tmob's edge/2g, and I can see AT&T's 2g and 3g networks when I search but I can't connect to them or they don't work if I do i'm guessing because i'm on a tmobile sim and obviously can't logon to at&t.
2. If it isn't band unlocked, would doing so unlock tmobile's 3g or is that just straight up not compatible and never going to happen with or without a band unlock?
3. If not with tmobile np, can I get 3g with at&t? Especially since I already can see their 3g network when searching.
4. Wether or not I am running a custom rom or the stocker....
It says it's running 2.4.330 A956.verizon.en.us kernel android version 2.2 kernel version 2.6.32.9 build number VZW
Not sure if this is the stocker or a pre-installed XDA Rom. It boots to a clockwork recovery tool screen too before actually booting into android. Is that something added on or is it on the phone already?
Thanks in advance for any help, so happy to have a badass new phone to screw with.
1. Sure seems like it. You wouldn't be able to use the T-Mobile SIM at all otherwise.
2. T-Mobile uses 1700MHz. The D2G does not support 1700MHz. Period.
3. Yes.
4. 2.4.330 is stock Motorola Froyo firmware.
In your case it would probably be better to SBF your phone to 2.4.29 or 2.4.330, and follow the instructions in the band unlock thread to get you to Gingerbread with band unlock.

I would be very careful with doing an SBF to an unlocked phone. An SBF would rewrite the radio firmware and very likely undo the unlocking that's in place.
The only way that it would be safe to do so is if he still had the unlock code, then he could just re-unlock and re-apply the band unlocker after SBF'ing.
Thanks for the replies. So I guess i'm looking at switching carriers at some point for the 3g. Honestly the 2g isn't that bad though. Plus I heard that since att failed to acquire tmobile, they ended up cutting some deal to share some att tech with tmobile. So some areas will get 1900 mhz 3g at some point. Probably won't happen to me but oh well.
As for the rom, I don't think I want to update just yet. I have no unlock code since it came that way already.
If I get a code though, since it's already unlocked and rooted (i'm assuming),
Do I just toss the sbf file on an sdcard and run the update? I've installed roms on my old G1 but I don't know the exact process on the D2G yet.

SBF files are something else completely. SBF files contain images for every aspect of the phone, from Radios, to the operating system, kernel, and more. Think of an SBF file as a Windows CD. It helps to wipe the entire system clean and installs everything factory fresh.
SBF files reside on your hard drive, and they are flashed to the phone with a Windows app called RSD Lite. The current version is 5.6. There are links to it everywhere around the forums.

Not sure if you read my post at all.
I stated that the safest bet is to perform everything from the start, including the band unlock process.
Why the hell would someone need the unlock code at all on a device that was already SIM unlocked?
I bought my phone off eBay, unlocked, and I have no SIM unlock code stored anywhere. I SBF'd it at least 20 times by now.

Well in this case, this is good knowledge to have. I presumed that an SBF would essentially erase a SIM Unlock because it rewrites essentially every bit of data stored in the phone.
Looks like there's something else going on in these phones when they get SIM unlocked. It's nice to know that SIM unlocks are truly permanent.
I am getting a prompt now for the new OTA update. Will this be safe to do in my phone's current state then? I just keep putting it off for now because I don't want to lose any of the sim unlock or my data ability.
I know it doesn't do much, but I think it might help my battery life which drains 90% every day with only very light use and only 2g data.
It appears that I am going to be stuck on tmobile until 2013 but I can probably deal, or trade it... So I want it to be the best it can be without being fast on data obviously.
SIM lock state doesn't change.
If you're on T-Mobile USA, you definitely have the US band unlock hack performed and if you update you will lose it with no way to rollback to 2.4.x baseband.
90% battery spent per day is normal for Froyo. I get 26 to 32 hours with light use on 3G with WiFi and GPS enabled on stock 4.5.608, used to get 16 hours on 2.4.330.
Hmm, well can I flash the new one. I was reading this earlier:
http://forum.xda-developers.com/showthread.php?t=1437177
Would that do the trick?
Otherwise, is there a way to stop it from promting me from updating?
If you flash the 4.5.608 SBF image, you'll lose your US band unlock.
To disable OTA:
Rename /system/app/BlurUpdater_VZW.apk, /system/app/BlurUpdater_VZW.odex, and /system/etc/security/otacerts.zip by adding .bak to their names (e.g. otacerts.zip.bak).
Ok, I will rename those for now. I was using Astro and it said permissions no allowing me to rename so so I am going to try another browser app.
So is there nothing I can do to get this update done and get back on tmobileusa? There's a way to band unlock it again isn't there?
How many times needs one to repeat that
USA GSM BAND UNLOCK IS ONLY SUPPORTED ON THE BASEBAND FIRMWARE THAT COMES WITH 2.4.29 AND 2.4.330 FIRMWARE
?
Well that's retarded, thanks motorola/verizon for steering me away from ever purchasing one of you phones again. Looks like I will be trading or selling my phone after all. I had an offer to trade for a samsung vibrant which can be flashed to gingerbread and has a bigger, nicer looking amoled screen that I think I will go ahead and do that. Way to screw up your customer base motorola. I USED to like you guys.
Did you mean: “OMG I'm a US GSM user and I wanted to use a Motorola CDMA handset made exclusively for Verizon on my GSM network and Motorola are such jerks because they won't let me”?

Seriously. I have no idea why he's being such a big baby about this. The phone was designed to Verizon's specifications by Motorola. It was designed to not work with Tmo/ATT from the very start. This was known by everyone at the time of the phone's release.
We were lucky in the first place to even get the ATT/Tmo hack. If someone isn't willing to put in the work to accommodate the requirements of the hack then this phone isn't for you.

I'm not, man. I already know why this is and have known since about 5 posts ago. BTW I bought this phone off of ebay a month ago and it was 'listed as unlocked for att&t, tmobile etc' WTF am I supposed to think when I read that? Stop projecting your in-depth knowledge onto all people like it's 'common' knowledge. It's not. That's like saying I should know Obama's favorite food or whatever the hell else for example. I don't know that nor do the vast vast vast majority of people. You know who does know that? Somebody who looked it up!
The only way somebody would know that this phone is locked out of tmob's 3g is by looking that up specifically. I would like to point out that I had the phone for at least a week prior to posting at all, all the while reading up on how to get my 3g before the kind folks on the 1st page answered the final question I had about that (which is the only way I know that now). So it took at least a week of researching to discover this.... We should really close and lock this thread since it's just wasting space with my displeasure about this phone purchase. $5 says this whole ordeal is the very reason the guy was selling the phone in the first place!! (He said he was currently using it on tmobile when I asked if it was unlocked for tmob...)
Is it okay to install a custom rom on a network locked Galaxy J4+? Like, my phone is under an internet plan and I'm afraid that if I'll install a custom rom I would encounter signal problems that's fixable on ordinary J4+ but cannot be fixed on a network-locked J4+. Should I backup NVRAM?
I've never heard about network locked J4+. You mean your phone can only use a specific carrier? Those variants usually only exist on popular series (like the S series on US region).
If your phone can be used with other carriers (just like my J415F) then it's safe to flash a custom ROM (LineageOS 17 recommended for now). Internet plan doesn't matter.

Yes my phone can only use data network from my internet plan. My phone can read other sim but I can't connect to it's internet. I was afraid to root this I might encounter signal problems because I found a folder in the root directory called /odm which contained the files from my carrier

Thank you by the way.
Sorry, I can't help you further as I don't have any phone that is network locked. You may want to take a look at other forums on XDA, especially on Samsung S series that I mentioned earlier. There may be a (universal) way that can also be applied to unlock your network locked J4+.
Based on your earlier post I can say that you're experienced enough to do that kind of stuff. Just make sure to backup everything and download your models stock ROM in case something gone wrong. Good luck.
Oh and I'm curious, where did you buy that phone? Because like I said before, network locked variants usually only exist on popular series. It's just (very) unusual to have a network locked J4+.

J4 Plus is popular here in our place when it was first released. Carriers then began selling them through installment with internet plan. Our phones cannot use data network from other carriers while the contract is still ongoing but we can insert other sim only for calls and texts. Data network is for the default sim only. I've had this for one year already and my contract ends this December 2020. I've had enough of Samsung's stock rom One UI it lags a lot right now. Seeing LOS 17 for our device hyped me up cause there's no bloatware and it's on Android Q.

So I am having remorse about going from stock Tmobile firmware to Global. The 5G connection just does not work well. I cant get standalone 5G and do not want to root to get this.
This is unfortunate because i like the way the global works with dual sim and less bloat but the lack of good 5G is not acceptable. I have tried to enable standalone 5G and it just does not work. I even flashed a tmobile modem and the phone would not boot so i had to flash the global modem back.
What is the easiest way to back to stock rom and if possible not wipe all my data?
Obviously i am unlocked but not rooted.
I am on Global 11.0.6.8.KB05AA and want to eventually get back to the current stock Tmobile as i received from the tmobile store when i bought the device. is MSM tool the only way? or can i revert back using a local upgrade assuming that the tmobile update is newer than what I have now? And where would I get a full rom of tmobile?
I am also on KB2007.
when I screwed up root and completely janked my boot partition the only remedy was MSM tool.
I could not find any images for the 2007 variant.
That was a month or so ago so maybe someone has pushed them out since, but im not aware of an offical repository of 2007 images.
I would love to see one if it existed though.
I did find the MSM tool while unnerving as I thought I had bricked my phone at the time surprisingly simple and effective to use.

I believe msm is the only way but I'm kind of in the same boat as you. As much as I like the global for the fact it has less bloat, i feel like the data connection in general was affected.
MSM is the way to go. I did it yesterday.
On global I could not connect to the 5G signal. The funny thing is at my location the 5G speed test is 1/2 speed of the LTE! Oh well!!!
It's been stated on various forums for various phones that 5G is not always faster than LTE. It all depends on where you are located, what phone you have, and what carrier you are on. 5G is still overrated for the next few years.

Hi
Have Samsung galaxy 2 fold at&t unlock
Can I change Carrier from att to t-mobile I flashing T-Mobile firmware or can I just Flash csc??
if your phone is sim-unlocked, once you insert a t-mobile simcard it will change the phone to t-mobile. no need to flash anything.

Yes, it works for making phone calls, texts, even 5g. But you won't get OTA updates. At least that's what I was told. I'm typing from a purchased AT&T unlocked Fold 2, with a TMobile sim inside. It works fine, just no updates. Still on One UI 2.5, and android 10. I'm actually here hoping to change this by flashing a TMobile rom. I did a little research last night, and it seems a little scary with the danger of bricking the phone. Back in the PPC hayday of flashing roms, I was all over it. I even flashed a few roms on my s6 years ago, so I have some experience with Odin, but it still seems nerve wracking because I can't return this phone if I brick it. Bought it used.

@vinscuzzy I feel you because I understand what you're going through. I used to flash my devices back in the day. I haven't flashed or rooted in a long time but like you, I also have an unlocked AT&T branded Z Fold2. It seems easy enough. Any reason why you would install the T-Mobile firmware rather than the U1 Unlocked version?

Theoretically I would think the unlocked version would be better because when theres an update, I'm guessing, we wouldn't have to wait for the carriers to do their stuff to it. But I'm not 100% sure if that's how it works anymore. The last truly unlocked phone I had was a Nokia 1520.3, with windows mobile, and it was great, BUT if I remember correctly I had trouble with wifi calling, visual voicemail, and tethering. I actually asked @zimgir124 the same thing in the other thread about which one is more beneficial, but haven't heard back yet.
Well, I just found another thread on how we can go back to AT&T in case we need to.
If it's running well now I would not be concerned with updates. You could well end up with a less functional device by updating.
