Oh boy. I've done something ..interesting.. to my new nexus s. Could you guys help me?
Okay, So I've been running miui for about a month now, and today I decided I will try the oxygen rom, along with a new radio (K3B). I flashed the radio over miui and all was fine.
Next I wiped and installed oxygen. No service. I couldn't even view available networks. I had a play around with the service menu (*#*#4636#*#*) and changed regions etc, but no luck.
The next thing I did was to try and revert to stock, by following the unlockrs guide (http://theunlockr.com/2011/01/20/how-to-unroot-the-nexus-s/). This seemed strange to me, as it was only a nandroid backup. Now I'm on 'stock' with no cell radio and a small wifi only tablet.
So, my real question is, can I fastboot or ODIN back to complete stock (radio, system, recovery, etc) or are there any other fixes for this problem?
Thanks! I'm desperate :S
Which Nexus S you got? Which ROMs you flashed exactly? Which radio did you flash, never heared of KB3b?
I'd assume you have a i9020T (since you used the GRH78 nandroid backup)? Then you could use the ROM in my sig to flash back to stock.
However, I never flash any nandroid backup that isn't my own, especially if they are crossing release numbers, eg 2.3.5 to 2.3.3.
I have the i9020T, flahsed the XXKB3 Radio (see here: http://forum.xda-developers.com/showthread.php?t=1116884).
I don't think flashing back to stock helps too much
Go here and get yourself a flashable full ROM for the i9020t, it will include a fitting radio (and a stock recovery). Remember to wipe everything before installing the ROM via cwm recovery. I'd also format stuff in "Mount and storage" (except sdcard for obvious reasons ).
Tried that. No success. I also used ODIN to revert to stock again. No success. Tried all the radios available for i9020t, none of them work.
My IMEI is intact still, my baseband /should/ be working, I really don't see anything more I can do except assume its a hardware issue. I'll give samsung a call now and see what I can do. Thanks for your help.
Maybe your carrier banned your IMEI for w/e reason.
Sent from my Nexus S using XDA App
I've tried multiple sim cards, and even if my carrier did block me (why would they do that?) I would still be able to at least view other network operators (and mine) in the Mobile networks menu.
Well multiple sim cards NOT working in your device could mean your IMEI is banned. Carriers block IMEIs for several reasons, stolen phones, contract abuse, carrier crossing, unpaid bills, etc etc.
Contact them and ask. If they didn't block anything you're still one step closer to solving the problem, next step exchange the SIM card, final step would be to contact Samsung and have them check for faulty hardware.
I'm starting to think thats the case.. My original sim card is dead and won't work in other phones now.
What I really don't understand is why they would blacklist me. I've been with my carrier for two years, since they started up. I'm a prepaid customer, so no unpaid bills. My phone is brand new, purchased it at Best Buy in the US four weeks ago
Maybe they were mistaken? I'll call them later in the day.
Ugh. I talked to my service provider, they said they couldn't do anything and were very unsure. They handed me over to samsung, who were unbelievably unhelpful and told me to turn my phone off and on, and that they couldn't do anything more. Just sent an email to my service provider hoping I get someone more 'higher up' who can deal with it.
Hello all,
I'm planning on picking up a D2G locally to use on AT&T. So let me get this straight:
1) Buy D2G locally.
2) Flash with 2.4.29 SBF using RSD Lite.
3) I would need to unlock the phone. Can I do this without having an active Verizon account to activate the phone? I realize I can get the code from various resellers but would the phone need to be active on Verizon's network or just previously activated on Verizon's network?
4) Apply the edit cellzealot specified here: http://forum.xda-developers.com/showpost.php?p=16572174&postcount=22
At this point I should be able to use it on AT&T.
5) From what I read I should be able to install and use non-Moto ROMs.
My biggest questions are with steps 3 and 5. Could anyone clarify those steps for me? Is there anything else I should know? Any fixes for the reception issues?
Thanks!
Hi
This is what i have just got done with my D2G and it work great on att . I got 3.6 mb down and 1.8 mb up in NYC . On your step 4 you shoud do this its much easier : w w.mydroidworld.com/forums/android-hacks/8942-tbh-us-gsm-band-unlock-droid-2-global-pro-update-zip-public-release.html#post98026
Good luck !
Thanks, warlord002! I read a post mentioning that update.zip but didn't really look into it. Using the update.zip makes this whole thing a ton easier.
Any recommended ROMs?

If you're lucky, and the purchased code works, you just input it and that's all.
Sweet, thanks for the help guys.
The phone isn't for me so I'll need a stable, functional ROM. I mean stock's always an option, but if there are better ROMs out there that are just as functional I'd rather use one of those. Suggestions?
Can you please explain step two for someone that is new at cdma phone hacking.
Picking up a D2G tomorrow morning. Are there any updates regarding gingerbread and the old radio? Any GB based ROMs out?
Also any websites that can give me the correct unlock code? Seems like its hit or miss for the most part and only Verizon has them forsure. I guess I'll have to do some social engineering and get that code from them somehow.

Well, JFYI: if you're on AT&T, you aren't getting Gingerbread.
Otherwise, Gingerbread update was called off and will be released later (“soon™”).
There is the update.zip from that OTA update, which can be installed.
There are some ROMs in development, but not production ready yet (at least on GSM).
Have fun with your social engineering, mostly because VZW wants you to be on a contract for at least 6 months to get the code.
Yeah I guess I'll stick with Froyo for the timebeing.
The social engineering is failing pretty hard. Tried at least 10 reps through different numbers and they all tell me the phone needs to be active on a line. My best bet now is to add some cash to the deal and ask the seller (vzw customer) to have it unlocked for me.

Many reps are telling me they can't even generate the code if the phone isnt active on their network. How true that is I don't know...

Picked up a D2G a few hours ago. The seller was nice enough to get the unlock code for me from Verizon!
SBFed to .29, rooted, bootstrapped, radio patched, and flashed to hexen all in an hour or so. No issues whatsoever. The D2G's running great on AT&T so far!
Glad to see a few more folks using this hack. It works well despite a few bugs in the original release build.
i got my D2G this morning, and soon ordered unlock code from ebay.
the seller get me the code IMMIDIATELY, and it works!
and the TBH's band hack helps me a lot. i'm now using t-mobile happily
Pls guys help me! I've just bought MY D2G from ebay, seller send my unlock code from verizon, I put it.. but when I inserted my new t-mobile sim, phone couldn't see any GSM network.. i flashed it already to 2.4.29, so what should I do next?
PLS help me, i really like this phone and dont wanna change it to another..

Check here - one more thing to do before you can get T-Mobile on your D2G. Remember you will not be able to get 3G - only GSM, but it will work nicely (and battery life will be great). Don't forget to set the phone to GSM only in the settings - so it doesn't waste power to look for a 3G compatible network all the time.
Apparently you can rip out the radio firmware from TBH's 4.5.606 and still install it via CWM; it works with 2.4.330's baseband.
The question is whether it's possible to make a 2.4.330 update that also doesn't touch the radio firmware, so you could flash 2.4.29 SBF, update to 2.4.330 and then 4.5.606 without touching the baseband, and thus gain Gingerbread with AT&T.
Going through the exact same process! But I can't unlock my phone, I bought it on ebay, the seller said it was unlocked but its not. I tried two of the unlock sim sites with no luck -$20 and two non functioning codes .. Is there anyway to unlock my phone?
Only via Verizon.
you are supposed to be given 2 codes..just in case one of them doesnt work. i got my code form the unlock shack and no problems
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...)
Hello folks, I am having an issue and am hoping someone can help.
My J700M shows no service. I have installed Argentinian firmware from sammobile website, and have tried a few others with no luck. I unlocked phone via Octoplus (or z3x, can't recall which exactly) and for some reason there is no service. I noticed the IMEI was bad after flashing firmware and unlocking phone after I first got it, so I re-installed the IMEI cert from a backup that one of the boxes made for me. IMEI is good and checks out, but no service.
Which firmware can I flash that would allow me to get service again? I live in a zone that gets strong signal for the 4 major US players. Or is there a modem I have to flash to obtain service? I'm so confused.
Another point worth mentioning, the one thread I found that seemed like it could help me informed me to use dialer commands to pull up a menu. No dialer commands work, so I flashed another firmware and was able to get the *#06# IMEI/SN dialer command to work, but the one the thread was mentioning still does not work. I believe it was *#*#4636#*#* or something similar.
Any help please? Would like to get this issue resolved so I can re-sell the phone. Donation of 15% of phones sale price to whomever helps me resolve issue first. or 10% a piece up to 40% if multiple people contribute to resolution.
If you have any questions, I will of course be glad to answer them as soon as XDA notifies me via email that I have a reply.
Thanks in advance folks. Cheers!
Hi,
I was recently gifted an unlocked ATT S8+ (SM-G955U) which I'm trying to activate to my Verizon account. I've read conflicting information about this, and after going to the Verizon store and calling them directly I'm thoroughly confused.
The rep on the phone told me that the phone is "incompatible" with their network based on the IMEI number. From what I gather, the hardware (and model numbers) on all the major carrier's S8+s are the same and simply have different firmware. I've also read that they're interchangeable. Has anyone successfully gotten the ATT S8+ on Verizon? I'm almost feeling like it's something where I would need to jump through more hoops and speak to a manager to get them to do it, but before I did I wanted to get others input. Thanks!
I heard that the phone will work, you'll need to flash the Verizon firmware onto the AT&T phone.
Thanks Richie. Do you think that Verizon is telling me that the IMEI is "incompatible" because I may need to flash another firmware to enable CDMA? Or are some versions of the S4+ really incompatible on their network.
May there be possible success to get them to activate it anyway?

The IMEI thing and Verizon not provisioning your phone to activate on their network is the ONLY obstacle you have.
All the US S8/S8+/Note8 variants are identical and can be cross-flashed to whatever carrier you want. You can easily grab the VZW firmware and flash it on to your AT&T device, fully converting it, however the IMEI won't be in Verizon's system since your particular phone wasn't sold by Verizon.
Somehow get around that and your phone will be fully compatible on VZWs network.

Don't worry about what Verizon reps are telling you because most often than not they are following a standard procedure. And they only Input your IMEI into a service like this one:https://www.verizonwireless.com/bring-your-own-device/#checkDevice
As your IMEI is for an AT&T phone, the brand model has an A appended at the end (as in AT&T).
However, you should still investigate this issue and try the steps recommended by the other guys. You will be able to use your phone with a VZV sim without reaching to Verizon

I have an AT&T S8 + on Verizon's network, had to unlock the phone, I did flash VZV firmware.
Works for me.
Thanks all for the responses! So it does look like I can do it then, but I just need to get Verizon to activate the new SIM. Think if I could find another phone that's compatible, throw the SIM in, activate, then switch the SIM to the S8+ it would work? (Assuming I've flashed the Verizon firmware on it).
Also, I'm trying to find out how to flash the phone properly. I don't really need root, but I'll take it if its easy. Thinking in my scenario, I'd follow this thread, correct?

Yes, if you can get VZW to activate a nano SIM then all you have to do is pop it in your S8+, and it will work perfectly.
You don't HAVE to flash the Verizon firmware, but you'll won't be able to use certain features such as VoLTE and WiFi calling with the ATT firmware, so I recommend it. Not a necessity though.
To change carrier firmware, follow this thread:

This is great information! I'll call back Verizon and knowing all this I have something to back myself up with to at least try to convince them to activate the SIM (if not, I'll find a temporary phone to activate).
Thank you (and everyone else) for all the help!
I was able to get Verizon to activate the SIM and IMEI of the new S8. When I checked my account online to verify, it shows the correct numbers. Unfortunately, the phone is still not able to make calls or connect to the mobile network.
Following this, I rooted and flashed a deodexed stock ROM/firmware that is compatible with all carriers. This made no difference in the issue.
On the status bar, normal reception for my area is shown. There is no data (LTE/3G, etc.) connection, however. In looking at the APN settings, there are multiple Verizon options to choose. "Verizon Internet" (VZWINTERNET) is what is selected. Under the network operators, Automatic is selected. I tried changing it to Manual, but I do not get an option to select Verizon. Only ATT or T-Mobile. Under SIM Card Status, It's says that I'm on an unknown network.
Any ideas on what I could do to diagnose this? Sorry for all the questions, but I want to be able to get this phone to work so bad!
Thanks!
Success! I was about to give up, but decided to try a few more things.
1) To register a new SIM on VZW, it needs to initially go into a VZW based phone to work correctly. Once doing this, I saw some changes:
- I could now see my phone number.
- Verizon was an option under the network operators setting.
This did not solve my problem, however, as I still could not connect to the network. When selecting VZW, the request would fail and say to try again later. So onto the next (and last!) thing I did...
2) Download VZW firmware and flash via ODEN (The Comsey version, but I don't think that matters). I added the BL, AP, CP & CSC (included in the zip file) using the default options. I found this firmware at the below link and grabbed the latest version. The download was very slow for me (I had to run it overnight), but numerous posters stated that they are a reliable source so I took a chance.

I'm just so glad everything is working now. Thank you so much to all who have responded to the thread to guide me in the right direction! Hope this helps someone else who may be having the same trouble.
