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.
I was wondering if someone could help me or point me in the right direction to avoid bricking my phone somehow.
First off, a bit of confirmation for anyone else out there... I have successfully moved my Verizon Galaxy S3 to Walmart Family mobile. Currently trying to (safely) rid myself of annoyances.
Bought a new device via ebay with clean ESN for Verizon (I'm unsure if it's still locked to Verizon network, see below for details)
None of the suggestions like *#1973 ... worked as my phone was on a 4.0.1 release (or so I think) I don't see any websites that would offer and unlock code and I read somewhere that the manual unlock needed something like 4.1.x or higher.
I used Odin to upgrade my device to 4.1.1 (Still couldn't find any unlocking info but..
Inserting my Family Mobile SIM card actually works (for calls and SMS) but the device still complains that it has a non-valid sim for Verizon. Going in to the Apps menu and killing the Setup Wizard 1.0 removes that message until the next reboot.
Optimally, I'd like to upgrade from 4.1.1 to 4.3 but have a few concerns.
Will an update rid me of the Verizon sim check? or is the sim checking piece not in the ROM but actually inside the bootloader itself?
I'm not highly technical (but dangerous enough I suppose).
When all is said and done I'm looking to have a 4.3 device with a Family Mobile APN that works (so far I don't believe that's occurred. Device is nice under wifi and says that cellular data is 'active' but I don't think it's working since I can't hit websites in cellular only mode.
Any suggestions for getting my device to a happy place without rooting it would be appreciated.
Thanks.
Being that I posted this for others as much as myself I'll go ahead and answer my own question.
After using Odin to bring my S3 (i535) phone up to rev 4.1.1 of Android using the Verizon image (only updating the AP, not the bootloader or other elements) I found online, I was able to cable the device in to a PC running Kies. After performing a quick backup I looked for potential firmware updates and was able to have Kies do the upgrade from 4.1.1 to 4.3. This removed most of my fear of applying something wrong (BL, AP, CP, CSC).
Once the update completed I was in fact asked to update to the new Kies 3 before restoring my backup. I can verify that running that update was smooth and the new Kies restored the backup created with the earlier version without issue.
The non Verizon SIM issue still exists on 4.3 but I continue to kill the Setup Wizard app after booting the phone and all seems OK.
I should also note that in 4.1.1 Verizon removed the ability to add APNs but that is now back in 4.3, so I was able to successfully update to the T-Mobile APN settings Walmart Family suggested.
Next month I will be attempting to move an unlocked global S3 mini GT-i8190 to Walmart Family as well. At present, the 4.1.2 OS is the latest release there. I do not intend to move that device to 4.3 at this time. I have read that it may be possible to rest the device and list is as Romanian (or some other eastern European country where Samsung did decide to offer the newest version to the public).

[I'd like to create a thread to collect information for all variants of the R530. I'll update this first post with additional information people give during discussion. Sorry it is here in the Verizon sub, but this is the closest model]
The SCH-R530 is a special flavor of the Samsung Galaxy S3 with sub-favors: (you should probably puke now)
SCH-R530U is a US Cellular variant
SCH-R530C is a Cricket variant
SCH-R530M is a MetroPCS variant
SCH-R530X is a Generic variant
I suspect these are all the same hardware, but just different ROMs. I would like to confirm this.
I would like to know and post the newest firmware versions for each. (at least the names, if not the ROM files themselves) I'd like to know if ROMs are compatible, if modem firmwares are compatible, if bootloaders are compatible. The small community of owners need to pull together as much as possible.
Model -- Hardware Version / Firmware Versions / Baseband
SCH-R530U --
SCH-R530C --
SCH-R530M --
SCH-R530X -- R530X.01 / JSS15J.R530XWWUBMK4 / R530XWWUBMK4
Please post if you can add to this information!
I'm working on my dad's SCH-R530X (Generic CDMA). It was on a regional CDMA provider that he was not happy with -- he paid $500 to them in January for the phone. Edit: Today, he's on PagePlus, but without data for some reason.
Concerns (that someone may be able to help me with):
Once you go to KK 4.4 you can not go back? Your bootloader is updated and will not boot 4.3?
I'm running 4.3, can I root -> replace recovery -> custom ROM ... without tripping the KNOX warranty void? I've read that saferoot will not trip KNOX?
This phone seems to have an odd Call Audio Quality problem. While listening during a phone call (on the R530), the other party's voice cuts out. Specifically, it cuts out when the other person isn't speaking in their mic close enough or loud enough. It's as if the R530 is filtering out anything under a certain volume level. I've turned off Call Equalizer and Noise Reduction to try to solve this problem. I believe I've read people say a firmware/ROM update from US Cellular fixed this problem.
So you can see, I have some constraints: Still in warranty and don't want to void it by tripping KNOX. Want to try a newer firmware for call audio problem. Don't want to brick phone with incompatible firmware, unless US Cellular will work on this X/Generic phone.
Help would be appreciated.
I do have the USC and Cricket variants but the USC version is soft bricked.
HW: R530C.01
Firmware: JSS15J.R530CVVUCMK3
Baseband: R530CVVUCMK3
Also fyi, this and the USC version requires a sim card.

Thanks... I'll add the info. I think I'll make a spot to record if it has a SIM slot too -- as my 530X does not have a SIM slot and was labeled with a little sticker "3G CDMA"... but the MEID starts with a "9" and LTE visible in DFS.

I have a regional version of the s3 as well, d2xar (sch-r530x) on Inland Cellular, primarily based in the north west US. as far as i can tell, i havent dissasembled my phone to see if there is a lte radio, in the original build.prop for my phone it is disabled on boot so it will not consume power since it is not being used. thus the 3g cdma only sticker. for the us cellular version i do not know if there is a kitkat firmware but if there is there is always the possiblity you will not beable to go back. as for the generic version it is only on 4.3 right now. eitherway the higher the bootloader version is better for customroms due to recoveries and features working better. as for saferoot i dont remember if it trips the warranty bit or not since ive long since written a custom recover to the device which tripped it but i do know itll make the stock rom list itself as custom in the settings after being rooted. also something to keep in mind with a custom rom is, unless you have the apns for your carrier eg, pageplus, usc, ect. you will not have mms capabilities. Im still tearing my build.prop and apn back up apart to see if i can include some of that info into a custom rom to fix mms, or a recovery that will inject it after a rom flash.
Update?

Last I checked there was a bug with the d2lte builds that break the ability to set apns... I made a cm10.2, I think, build that allowed changing the APN. Um if I remember right the physical design of the d2xar has hardware similar to the Verizon s3. I still don't know if there is an lte modem in the phone since there doesnt seem to be a sim card slot, though there maybe an integrated uicc. I haven't played with it much since I switched to using my nexus 5 on T-Mobile.

I got to the service mode settings, which oddly enough it listed GSM and CDMA. Quite weird. To get there was even weirder. Sadly the D2xar doesn't support TWRP Recovery, and the only one that works is CWM by Philz.

Yah I noticed that to when I was digging around for apns for my old carrier. As for twrp I got around that problem by building my own version using cyanogenmod and the d2lte device files. It made cyanogenmod delta updates possible on the d2lte build. Which are really nice. My source is floating around github, though you'd have to do a little digging to find everything. I do have precompiled twrp images on my webserver that I try to keep up to date for my friend who's brother has the same phone. If you go to my site its safe to ignore the certificate warnings, I have it set to force HTTPS and the reason the warning pops up is because I self signed it instead of paying for a company like verisign
Sorry for my superbly late reply. I've done a ton of digging with this phone. Turns out it only supports Evdo. So no LTE sadly. Even worse, using the Test Menu I can't bands to USA bands, only the (800 or 850?) Hz Global band. I can't get a connection. Well. The bars are listed as 2-3 generally, but it says "Roaming Indicator Off". I have the latest and only baseband, too.
(Wow. After two months of fiddling, as of typing this, I turned on cellular service, which is usually in Airplane mode, I got a " 3G" connection for the first time. Only for a second.)
I don't think I'll be able to switch this over to Straight Talk any time soon, though. I'll check your GitHub soon for that TWRP.

Yeah, just of now I've been unable to re-acquire the "3G" that caused me to have a boost of hope. Now even when I attempt calling which it usually would bring me to the Verizon automated system, asking to make a collect call, since around here is primarily Verizon, I can't even get it to call. It now states that no mobile network is available, even when I have 2-3 bars.
You have no "3g" because your keys are wrong. Y'all need some QPST and see the whole logon process and baseband messages. Then you can really troubleshoot your phone.
I have a Verizon Samsung Galaxy S3 on the Straight Talk network. I check for software updates and it tells me the software is up to date however it says my phone is running off of 4.4.2 instead of the Lollipop or the one just under. Does anyone know if Lollipop 5.0 or 5.1 has reached the S3 yet? Or how to manually update my phone software so its not so low?

I do not know. I'd love to take the chance, but the risk of totally bricking the R530C is there . . . heck, let me try it.
I just pulled the trigger on a refurbished SM-P905 (Verizon) tablet. I would like to have the option of sticking my phone's SIM card in it and use the tablet as my phone (with an ear piece, of course).
What would I need to do to the tablet in order to make that work? Root? Install additional apps? Would CM12 work?
Assume that I have a Verizon cell phone that I would pull the SIM from and put into the tablet when I needed to use it as such.
Thanks!
I have the international version of the note pro SM-P905
from my previous knowledge,
any android tablet can be used as a phone except that phone calls will be heard through the speaker unless you use an ear piece.
I already have a phone sim installed on my note pro and it is working fine out of the box
I use it the sim for data and I made a few phone calls without any problems
no need for root or anything else
I don't know about Verizon note pro model but it is suppose to be the same
Thanks! I was concerned that the tablet wouldn't have the necessary phone apps and background software that it would need right out of the box.
I have the P905V as well.
I haven't tried a phone sim on I cant say for sure on the phone calls themselves.
however I am using a T-mobile tablet sim with text messaging and the text messaging does not seem to work on this tablet.
Verizon and sprint use CDMA for voice, SMS and 3G data
When they moved to LTE (Which is a GSM technology) they basically just added a sim card slot for data on top of the existing CDMA hardware.
Some Verizon phones also have the Sim slot enabled for GSM calling for people that travel internationally.
unfortunately most tablets (and even a lot of phones) dont have that feature and only use it for LTE
I suspect that this is the case here.
there is chance it might make calls if activated under Verizon though you would need a dialer installed. (Perhaps someone with one activated with Verizon could chime in if they have tried it)
The best option I've found on an alternate carrier is to use your google voice number in the hangouts app to make VOIP calls.
it works great for that and you basically have calling coverage anywhere you have data.
Groove IP also works pretty good and doesnt use much data.
unfortunately VOIP is the only option I know of.
On a side note, as stated above the international version has the full phone features in GSM format, this is often the case with international versions of tablets.
Sadly the US only versions often have things stripped out by the carrier, sometimes out of necessity and sometimes to push people to use their service etc.
Thanks for the info! That's exactly what I was afraid of, that the Verizon version of the OS on this tablet wouldn't include the phone/texting software. So I'm wondering if the CM12 rom does..?
Unfortunately while the Verizon version is rootable on android 4.4 there are no custom roms for it currently.
Also note that they released the 5.1 update for the Verizon model but its not yet rootable.
I've kept mine on 4.4 for this reason but a lot of people have opted to give up root for the newer software.
I know this all sounds like bad news but this is really an amazing tablet, I actually use it exclusively and no longer use windows at home.
I also often use it for calls over VOIP.
but unfortunately if custom roms and voice calls are what you are looking for in a tablet the international version would have likely been the better choice.
The Verizon Version does have a few perks due to the snapdragon 800 processor, charging faster being the biggest.
Thanks! I just purchased mine and its supposed to get here tomorrow. I'm probably going to send it back. I don't want to be stuck on 4.4 just so I can have root, and I don't want to deal with not even having root on 5.1. Then add-on that you can't unlock the bootloader on the Verizon version, and it's a no-go.
I'd like to get Wifi calling, Visual Voicemail, and 4g on an unlocked A515F.
As of now the phone reports itself as this:
Baseband A51FXXU3BTH5
Service provider (stuff) TPA TPA TPA TPA
Network AT&T
Moble network state disconnected
Service in service
IMS not registered
Mobile voice LTE
Mobile data LTE
VoLTE seems to be on? I thought this doesn't work on unlocked phones.
Being new to this the providers are all over the map on all kinds of stuff regarding unlocked phones. (AT&T rant I'm sure many of you have been here Grrrr.)
Network mode auto is LTE/3G/2G, there is no 4G option (as I believe in my research is how it is with unlocked phones)
So, I suppose the question is, if I follow the steps outlined in this thread:
https://forum.xda-developers.com/galaxy-a51/how-to/guide-how-to-change-csc-a51-t4129243
and flash the AT&T firmware, will I get 4G, Visual voicemail, and WiFi calling? As well as whatever the heck ATT disables for unlocked devices.
Will this require another trip to the store and a 4G SIM put in there?
New to this, but I have tried to research this as much as I could. Thanks for all the info.
Steve
Forum?
Have I put this in the wrong sub forum? Should it be in the firmware flashing forum?
First don't need to flash anything unless you want to waste your time with bloatware.
What you have to look into for your service desires, is do you have wifi in your service plan? If yes, did you activate it on the A51 you are using? (Also make sure your sim card is sim 1)
Also you don't have to use any provider's visual voicemail to get it for your phone. I've used YouMail for about 2 decades.
As far as lte & 4G. My phone is from same csc TPA TPA/TPA. I've seen both 4G & 4G LTE on my service. So your question about that was a little vague. But U.S. providers (at&t or tmo) won't tell you 90% of the time that you have to get 4G LTE sim card & pay for a 4G LTE service plan on order to get it.
Thanks for the reply.
It's sim 1. IMS not registered my be the issue, ill call ATT tomorrow.
I've been able to get visual voicemail back by installing the APK. The play store says it is not compatible with my device, APK was fine. I will check and try what you suggested.
Yeah, it might get a few chuckles here but i've had a S5 for years, and replaced it 3 times with ebay s5's. Love it. Initally i just popped my old iphone 4 sim in there and used it forever. I never had wifi calling and when i attempted to enable it it said the sim was the problem.
Imagine my surprise after going to the store and getting the proper sim i see the 4g icon appear and wifi calling, etc. All these were ATT firmware phones, on power the logo pops up, bloatware, etc on the S5's. Miss it already. What am i going to do with all these batteries and chargers?
This has been a different thing. Being in the States, not traveling overseas (at this time i believe no one will have us anyway) and this unlocked phone. As far as bloatware goes, its still kinda there in one way or another. Clicking on a link within chrome forces samsung internet every once in a while. Yeah, there is no real extra stuff on the device as it is. Its just weird.
Getting a sim for this at the store took a little more time then I thought it would. The employee was checking out the phone for a little longer then just handing me a sim.
I've changed the APN, possibly to the incorrect settings, to get 4g and wifi calling bacK. But that seemed to knock out any mobile data. Granted I may have entered the wrong settings. I'll look for others.
What's really confusing is the lack of these things. Is this phone cabible of 4g in the hardware? Wifi calling seems to be a forced ATT unlocked thing.
Sorry, long winded. This article states that when I am seeing the 3g lte it is really 4g.
Egads, link without 10 posts wont let happen. It's the B&H photo article regarding unlocked phones.
The wireless calling is not happening. Is this inherent to unlocked phones on ATT? VoLTE is on as far as the settings tell me. I'll poke around some more.
Many thanks
Steve
4g was on the S5 so i would assume it was part of the plan. Switching to the nano sim A51 should not knock that out.
I've read so many posts here, as i know my questions are pretty basic compared to other discussions, so thanks again.
If you'd like to discuss the numerology hidden in octal permissions let me know
If there was a screenshot of the mobile networks
Data roaming off
VoLTE SIM1 On
LTE/3G/2G (auto connect) checked
3G/2G (auto connect)
3G only
2G only
Yeah, I just bricked it ish. Tried the A51U-1 At&T firmware USA. I'm downloading the Italian Samsung firmware to get it back I hope. "Only official binaries are allowed".
The phone was in emergency mode and showing the PIT error with the A51U1 firmware.
The Italian firmware set uploaded fine. Now only it only shows a white circle with the little lightning bolt inside if connected to a usb cable. Computer wont recognize it. Resetting it vol down and power/bixby key turns the display off for a sec but it comes right back to the same thing. This is bricked huh. Any ideas?
Holy cow I held the vol down buxby bixby button down as I removed the usb cable I am getting the factory data reset screen. Maybe there is hope.
Yeah same thing again. If anyone has this issue you can at least get back to factory reset by holding the buttons and quickly yanking the USB cable out when the charging logo disappears.
-edit again
Recovery mode vol down + power. When it blanks keep the power button down and push vol up.
I wonder what to try in the choices.
Wipe cache?
Reboot to bootloader?
Im looking at the last log there is a whole lot going on. At about 80% of it is shows a ******FILE SYSTEM MODIFIED****, then it looks like its setting the octal permissions on a bunch of stuff, then it looks like it cant find /etc/firmware/calliope_sram.bin and from a bunch of other places in the filesystem.
After about 87% it looks like it is basically describing how it is displaying the recovery mode screen.
Displayed is samsung/a51nsxx/a5111/RP1A.200720.012/A51FXXU4EUC8
The phone came as an A51F. Was trying to flash to A51U1(ATT).
-Edit again.
I have hope for this but I am aware I am a flippin second from bricking the device. Any input is highly appreciated.
Steve
I will attempt this if I can find the download screen,
[RECOVERY] TWRP For Samsung Galaxy A51 SM-A515F One UI 3.0 DUB1 Android 11
Assalom-o-Alaikum! How to Root and Flash TWRP on Samsung Galaxy A51 SM-A515F Android 11 – Build number DUB1 – Android security patch level: February 1, 2021. The TWRP version is 3.5.0 developed and brought to you by [email protected] senior...

looks like is TPA for Panama, Downloading firmware through Samsung firmware downloader. But I would like the USA ATT firmware so I can have 4g and wifi calling. OMG Im gonna brick this thing.
Reboot computer and phone reboots into Cyrillic I find this rather funny at this point. But it is the phone setup screen and routine.
edit-- Hilarious. Didn't even install the Panama TPA firmware unless Samsung Firmware Downloader did it by itself while I was taking a nap. Cyrillic boot? looks like it is on the network at least I think can talk to someone been a lonely couple of days.
edit again== This is a linux computer that can make phone calls. WTF is the deal here. Really? All this stuff? I'm exploring all the custom ROMs and whatnot here in the forums. All I wanted was 4G and wifi calling. That is what my S5 did and I loved it. The S5. Flippin old phone but a fun one. Thousands of dollars to ATT over the years and they wont turn this phone to 4g on for me?
Thanks for everyone that has put effort into this that is amazing I really cant thank you enough.
edit yet again. Maybe flashing the firmware I have to wait for a couple of hours for it to fire up? I am assuming everything I am doing is wrong.
Can do... https://forum.xda-developers.com/t/guide-how-to-change-csc-on-a51.4129243/

No bloatware but the Yandex stuff.
No ATT logo on startup.
Again thanks for all your work and knowledge on this stuff, I'll poke around some more and see what firmware is actually on there. It says SM-A515F/DS.
Oh! A515FXXU4EUC8.
SER/SER,SER/TPA
Again thanks - ramblings form a newbie.
SER CSC, well that explains Yandex.

First don't need to flash anything unless you want to waste your time with bloatware.
What you have to look into for your service desires, is do you have wifi in your service plan? If yes, did you activate it on the A51 you are using? (Also make sure your sim card is sim 1)
Also you don't have to use any provider's visual voicemail to get it for your phone. I've used YouMail for about 2 decades.
As far as lte & 4G. My phone is from same csc TPA TPA/TPA. I've seen both 4G & 4G LTE on my service. So your question about that was a little vague. But U.S. providers (at&t or tmo) won't tell you 90% of the time that you have to get 4G LTE sim card & pay for a 4G LTE service plan on order to get it.

Consider myself lucky running SER TPA firmware?
Am I about to trip Knox?
Welp, getting the 3G going away feb 2022 messages from ATT even though it does display the little 4G icon at times. Called Att they say they can see the imei. They say sending a new phone. Not an a51 who knows. Most likely some thing that up the account to $100 a month.
Be warned the you will loose everything is real on firmware flashing but weird. Thought i copied the entire filesysyem but things dropped out
.
This is an old model phone so i understand and my first shot at flashing it. Probably try again as i think i did not flash the u1 correctly. Still can talk, text, whatever. Frustrating, old phone, who cares.
Ah they sent me a S10e for free no complaints. Ill try the att a51 firmware again nothing to loose at this point see what happens and follow the guides.
