[Q] [XT860] - Vivo 2.3.5 vs Bell 2.3.4

Hi All,
Noticed that we finally got a new version up from Vivo (running in fastboot) 2.3.5. I was wondering what differences are there between the stock Bell ROM and the Vivo ROM?
A few key notes I'm interested in:
1) Is the camera working better? IE Bluish tint or not?
2) Has the hardware repeat key problem been fixed?
3) How is the battery life?
4) Does HSPA+ still work when using the Vivo ROM?
I'm also considering jumping ship, but not fully sure on the Bell firmware. How could I take a full backup of the entire system? Is it even possible?
Finally, I think the question we are all wondering, who do you think will get ICS first, Vivo or Bell?

I have a few questions related to this ROM:
1. Does it have the improvements that the XT862 received for radio battery life?
2. Can we root the firmware?
3. Can we use the firmware on our XT860 from Bell?
4. Is there a subsidy lock built into the firmware, or is that only Radio?

I don't know the answers to questions 1 and 4, but here are the other answers:
You can root the firmware, more information here: http://forum.xda-developers.com/showpost.php?p=18936239&postcount=66
Yes this has been tested and works, but I'm not sure about going back to the original Bell firmware yet.

I ran the following test:
1. Charged the XT860 to 80% via USB power
2. Stuck a SIM card in it, and configured my APN for Fido
3. Forced the device to only use 3G UMTS/HSDPA for data connection
4. Disabled the sync power saving options
5. Unplugged the device from USB power, and left over night (approximately 8 hours.)
Device was at 80% when the tests were complete, with Cell Standby being below other tasks on the device.

... I would imagine that the place to discuss this would be the actual rom thread here, that way we don't have 20 threads open to discuss one rom. Makes a lot more sense to me to have changes listed in the OP on that thread, maybe you could message them to the original poster as well and ask him to update the post. Good example, if you're looking for info on CM7/droid 3 you should just have to check that thread instead of scouring the forums.

The other thread has 3 ROMs for download, this thread is specifically for the Vivo thread...

I would say that all info about those 3 roms, questions regarding them should be located in that thread rather than spread around different threads, forums and subforums in multiple posts. Curious that you think the opposite.

Guide - Unlock XT862 for T-mobile/ATT

Thought I would share based on my experiences on trying to get this phone to work on t-mobile. It works on ATT 3g/T-mobile Edge, but still a pretty cool phone to have.
Also another note, this is a mod that will only go through on Windows. You will need ROOT EXPLORER app for this method to work.
1 - Make sure you are on the stock XT862 ROM, if you aren't flash it via this method found here: http://rootzwiki.com/topic/4370-sbf-droid-3-fastboot-files-55959-and-56890/
2 - Make sure your phone is rooted, if not download the following and follow the steps found here: http://www.psouza4.com/droid3/
3 - Unlock the phone. This can be accomplished by purchasing the unlock code, and later entering the code upon insertion of a sim card. (T-mobile ATT sim cards will work, but you will get an error saying UNLOCK FAILED, this is NORMAL do not freak out)
4 - Download the following files and unzip it to your desktop: http://www.mediafire.com/?y1wjw775v8itsx3
5 - Click Start and open cmd.
6 - Type in the following in cmd:
'cd desktop'
'cd fastboot'
'moto-fastboot flash radio radio.img'
ONCE it flashes, then enter:
'moto-fastboot reboot'
7 - Use root explorer to push the build.prop into the system folder
8 - Reboot, select GSM/UMTS in Network Settings.
AND BAM now it works. If there is any confusion please let me know.

Nice! Is that the XT883 radio you're flashing or a real unlocked (and signed) XT862 radio?
Also - change
Code:
ro.mot.phonemode.vzwglobalphone=1
to
Code:
ro.mot.phonemode.vzwglobalphone=0
in build.prop to get normal reading on signal strength indicator.
You can also change
Code:
ro.telephony.default_network=7
to
Code:
ro.telephony.default_network=3
so phone starts automatically in GSM/UMTS mode after hard reset.

Can anyone confirm that it's running on AT&T with 3G/4G?

Thanks man I'll reupload when I get back home with the edited bits . It is the XT883 radio.

Nice Guide!
I've read some people have had trouble unlocking the D3....and apparently it could be due to it being used on the Verizon network who then alter the unlock code via some update.
Anyone know if there is any truth in this? (I'm awaiting the delivery of a used D3 so would be handy to know).

Even after the update, if you restore it to the first link and then follow the steps, you will be fine. It can still be unlocked.

Awesome! I am about to try this on my friend's droid 3. Are there issues with the market (as some have mentioned in a previous thread)?
---------- Post added at 12:10 PM ---------- Previous post was at 12:00 PM ----------
I am stuck on <waiting for device> in the command prompt after telling it to flash the radio. What sort of USB connection should I be selecting?
EDIT: I'm an idiot.... I figured it out!

Is anyone else who is using this method on AT&T experiencing super slow data speeds? I have tried the sim card in an at&t branded phone and it seems to work ok. On the Droid 3, I am getting a ping of 2500~ ms, and speeds in the 15-60kbps range.

I can't seem to add an APN and connect to the 3G network. Does anyone else have this issue? I am using a Bell SIM at the moment

Follow all the steps, no luck here
When I put the unlock code, phone shows for a sec "requesting unlock" and goes back to a subsidy lock message with a discard dialog box.
After that, I followed all other steps, and still enter unlock code appears
Any ideas?
I dont have an att sim card, Im just using foreign sim cards cause Im outside US.

You can always call the carrier and make sure they are allowing your phone to connect. I'm not sure if this is the problem, but I read about another AT&T branded 4G phone (the D3 will never get 4G) getting only edge because the carrier thought it was foreign, and they just called in and gave the IMEI number to get access.
The customer service rep may not understand your problem, but just tell them the truth that you want to use your compatible device on your valid account and they should redirect you to someone who can help.
I can verify this works on T-Mobile and AT&T since I've tested it on both. Didn't test 3g on AT&T though cuz I didn't think about it lol. I know it allows the connection to umts in the settings though.
The OP poster helped me get it working on my phone just make sure you follow the directions closely and it's pretty simple. If your unlock codes aren't working because you got them off the internet, you may need to have the phone put on Verizon temporarily to get them to give you a code. Just ask a friend with a valid account to help you out.
Good luck to everyone, this is a great hack that definitely saves some money while letting us use this cool phone. I will have to edit my build.prop as mentioned above to fix the reboot network loss problem, thanks for that as well!
Droid 3 with stock xt862 ROM working on T-Mobile via xt883 radio.img & custom build.prop

If verizon changed the codes while phones are connected to his network, changes could only be stored on a new bootloader.
There is no other unwritable part on the phone.
Wonder if the original poster used an ebay code or a verizon one...

Nice job! Pretty amazing what can be done with fastboot and signed radio images!

Custom ROM
What will happen if somebody follows this procedure and unlock the phone for AT&T but afterwards flash another rom? Will the radio still be unlocked for AT&T?

As long as that ROM you're flashing does not have radio image in it, you should be fine. If you meant sim lock - once unlocked, it will remain unlocked forever.

I was asking about radio unlock, i know sim unlock is permanent. But has anyone tried to install any rom after the radio unlock and if yes which one?
thanks

Now, I haven't tried flashing another ROM since flashing the xt883 radio.img, because I really don't mind the stock ROM with some build.prop tweaks and the help of Zeam Launcher. I would assume that any ROM you flash would cause the build.prop and radio.img to be replaced with new ones, made specifically for that ROM. You should probably consult with the developer of the ROM you want to use, and ask them if the build.prop changes specific to this process will have issues with their ROM. The xt883 radio.img shouldn't have any conflicts, but I believe it will still require the custom build.prop file which is found in the OP, or at a minimum the specific changes which allow this tweak to work.

Domestic Unlock of 4.3 & 4.4.1 (NAE) galaxy s4

Okay, I just got through doing this myself and it seemed that nowhere was this all said at once, or at all. So I thought I'd whip up a quick tutorial concerning how to Domestic Unlock the Samsung Galaxy S4 on any of the newer bootloaders/firmwares/modems. (Knox-enabled)
I did this on both a 4.4.1 galaxy and a 4.3 galaxy- one one NAE and one on MK2
First, for anything to work your modem must be an older one, like version MDL. Download the file SPH-L720_MDC_Modem.exe which is a one-click
Odin .exe that will flash ONLY your modem to MDL.
Steps- put into download mode by taking the battery out and putting it back in. Hold the volume down button, the home buttone and then press the power button. When it vibrates, let go. Press volume up.
Run the SPH-L720_MDC_Modem.exe odin one-click installer.
Connect the usb to computer from phone
when com[24] or whatever shows up, press start.
Now, for the domestic lock to work you first need to do the international unlock @ http://forum.xda-developers.com/showthread.php?t=2415587
It's real easy and explained well at the link above, but I'll run through it quickly anyways.
Download the s4unlocker installer from the post linked above.
Put your phone into diag mode by dialing ##3424#. Press Qualcom button and select the bottom selection.
connect (if it wasn't already) usb from phone to PC
You already installed the proper samsung drivers, right? If not, you'd better do that now.
Okay, now run the s4unlocker and press the scan and unlock button, then wait for the phone to reboot.
Now for the Domestic Unlock part.
Follow the directions at http://forum.xda-developers.com/showthread.php?t=2530610
I'll run through it real quick, too because there were a few things I wanted to mention.
dial *#0011# (or #*0011#, I can't remember)
when it comes up "No service", press the menu key on the bottom left of your phone. This brings up a menu (wow!), on which you should press "back"
Now press the menu key again and in the menu select "key input" A box will open up asking for you to type in something- enter a "1" and then press the enter key BEFORE hitting the OK button. Mine would not work unless I did this.
Now wait, sometimes it takes a good couple of seconds to give you the menu. Follow the rest of the directions from the above link, setting all the settings to what is stated. EXCEPT where he says to set all the preferences to WCDMA ALL, GSM ALL and LTE ALL. When I selected one, however, an asterisk appeared after my selection leading me to believe that you can only select one of these and so I set mine to GSM ALL and left the others alone. This worked for me, so I thought I'd mention it.
Now that you've manually rebooted after following the directions, you still have to edit your build prop to allow you to edit the apn settings. To edit your build.prop you must be rooted so root with CF auto-root http://autoroot.chainfire.eu/ download the proper one for the galaxy s4.
It's just an odin flash, so enter download mode
load up odin 3.x
hit the pda button and select the cf auto root tar
hit start.
After rooting I found that one time I had to do some of the service mode settings again and one time I did not, so I mention it here even though I think I had to because of some other error I had made at the time.
Go to play store and download build.prop editor and APN settings Shortcut
Load the build.prop editor and add these two lines to the end of the file
ril.sales_code=LOL
ro.csc.sales_code=LOL
Now reboot manually
add the apn settings widgit to the main screen and open it
click on menu and add an apn
Enter the apn settings for your carrier here. They're all different,(the carriers) but you can find them(the apn settings) easily with google, since they (carriers) all post their apn settings on their webpages.
Don't forget to save the apn settings.
Now select it.
Now reboot, since it couldn't hurt, right?
If you've done everything right you should now have an domestic and international unlocked Sprint galaxy s4. Enjoy.
I suppose you could now reflash the new modem back onto the phone, but I don't have firsthand knowledge whether this works or not- I've only read that others have said that it works. Remember, ONLY FLASH THE MODEM, the rest isn't necessary and will probably knox you all up
All I did was list these things- credit goes to all those who were linked in the above post. Thanks for all you do.

On stock 4.3 and higher you can go into settings and change your APN, so there's no reason to root and mess around with build.prop editor.

Every time i try this i cant get my wifi back up when i flash back to the nae modem. If i could get pass that then I'll definetly be do that.

I have read that the modem itself cannot be downgraded. You can run older android versions and such on the newer modems, but the modem itself cannot be rolled back. I believe it has been like that since MJA.

You can downgrade modem, but can not downgrade bootloader (aboot)

I completed both the international & domestic unlock. I believe I was successful in each. I have a T-Mo sim card inserted but am not getting a mobile data connection. I do have 2 bars of service though. So I have gotten past the red X on the bars.
I am on 4.4.2 with the MDC modem. I did not do the build.prop stuff, instead opted to just access the APN's from the default menu.
A few things in my menu were different than the OP (probably because of 4.4) such as:
I dont have any roaming menu options
I dont have WCDMA.. just CDMA and LTE/CDMA. I currently have it set to LTE/CDMA
In my APN edit info there was not a place to put in MMS protocol: WAP 2.0
Also under About Device "my phone number" is wrong.
Am I missing something to get this t-mo working?

You didn't unlock it. If you were on NAE modem while unlocking then you failed miserably because you're not able to get into the most important part of the unlock...The service menu. If you did indeed downgrade the modem then you're going to need to follow the domestic unlock guide again. If it's showing CDMA/LTE you didn't do it right. It should show WCDMA only and WCDMA only isn't an option you can just select. It gets put there by the service menu.

I said I wasn't on NAE, I am on MDC. I did get into the service menu. I did everything in the process without issues. My service menu did NOT have a WCDMA only option. It had LTE/WCDMA and that's what i chose. I just went to the t-mobile store and they verified my APN settings were correct. I am unsure of what to do at this point other than just start all over and do it again.
Anyone else?

I apologize. Long work day. Follow the guide. When it comes to where it says select LTE, GSM, and WCDMA all, ONLY select WCDMA all. At no point should you see your Sprint phone number in about phone. Also you should see IMEISV in about phone as well if you've successfully unlocked it. It'll help if you posted the steps you've gone through. Otherwise were just shooting in the dark.

Imeisv visible, definitely unlocked as i can make calls texts and use edge data on redpocket mobile (att mvno)
But in phone number I still see my sprint number and I can't get hspa (picking the wcdma all gives me red x no bars, picking gsm all gives me full bars and edge data)

From the S5 thread and now here we meet again in a revisit in time. Since I know you own and understand the L720 more than I do, could you please explain to me if this will work on a 4.4.2 NAE rom? I picked up an L720 (bad esn) for $100 and its in pretty great shape. Now I'm looking to unlock it but my experience with Samsung devices are very mild. It came on CM10.2 (4.3.1) and ive slowly caught up with things. So i understand that sadly there is no such thing as downgrading from KK to JB, I was trying to get it stock on JB with no cigar. Elsewhere I found out that you must flash something identical or above. So im planning on flashing an NAE 4.4.2 stock rom (custom recovery flashable) I found in order to attempt to unlock it cause I can't seem to find a 4.4.1 as mentioned in the OP. I flashed the MDC modem and it stuck, so with little knowledge I am assuming that it will stick once I flash this new rom? Correct me if I am going down the wrong path...
EDIT: Great nobody ever mentioned anywhere that the software used on the international unlock is for 64bit only...

The software works on 32 bit too. Actually you can even perform the international unlock WITHOUT the tool if you know how to use QPST or DFS. Anyway...
Flash full NAE. Flash MDC modem. International unlock. Domestic unlock. Win.

Must be an issue with my PC, nothing new...
And I know a thing or two about QPST. I still have it on my computer from a few days ago from when I was fixing a horribly corrupted IMEI on a G2 a friend of mine bought. I'm assuming I have to use a NAE stock tar with ODIN, because I tried a ROM of it and it lags and stays on black screens for seconds and WiFi doesn't work im sure because of the fact that the modem is older than the rom. Let's see if that works cause ive been trying to flash back to any stock ROM since I got this thing yesterday.

(Almost there...)
NEVER MIND. Got the international part working perfectly by using the Windows Vista partition on my PC. Now reading on, OP mentions that next the domestic unlock must be done, a link is provided there to another thread with domestic unlock instructions. Heres the question. The OP in the other thread mentions to hop onto 4.3 via odin. How can I get to 4.3 to domestic unlock if Odin doesnt let you downgrade?

Read the specifics. You cannot downgrade boot loaders but you CAN downgrade modems.
Unlock just requires MDC or MDL modem.

Yeah I remember that part but from what I was understanding, that's for the international. Domestic requires messing with some files and done. I already got the international part by tossing CM10.2 along with the MDC modem because stock Touch wiz would cause lag and reboots and non working wifi I'm assuming because of the mismatched combo. I DO know that obviously we need a TW rom in order to unlock domestic.
EDIT: I finally got the hint and got it to work. But I only get Edge instead of 3G. Does anyone know where I may be able to find that T-Mobile rom made for us? When I Google it I end up on the T-Mobile side.

I downgraded from latest bootloader on 4.4.2 or was it 4.4.4? Down to 4.3 which is the absolute best ROM version for service mode menu. It got me into service mode menu on first try by selecting menu back and input of 1. What I did was first install cf autoroot to root then cwm and used cwm to flash the 4.3 stock deodexed, I only used Odin for flashing modem. Odin gave me an error when flashing modem and phone got stuck in kies mode but i got it to get unstuck by just flashing cf auto root again to make the kies mode error thingy think odin flash has went well. Turns out MDC modem flashed despite odin error.
Anyways. While on 4.3 and MDC modem I noticed no WiFi but I had sound. I followed the international and domestic unlock instructions and WiFi was still broke when I got back to 4.4.2 but I had unlock and sim card working and got bars. I am on aosp 4.4.4 now and the nae modem I finally flashed works well with this ROM but soon I gotta go to touchwhiz 4.4.4. If I go to 4.4.4 touch whiz WiFi and all else will work fine just as they do on slim aosp . 4.4.2 touchwhiz is still not giving me wifi on NAE modem. Update NAE 4.4.2 stock deodexed rooted rom i got from xda android thread did the trick and all works well now. All is perfectly working after i flashed it in cwm.
For aosp lovers. aosp requires additional things to do so aosp dialer can make and receive calls fine. I can call but there are issues until I follow another guide on xda that resolves those issues on aosp ROMs using sprint s4.

If you see system slow, no wifi, no audio and lockscreen being nearly impossible to unlock, its due to you being on a higher ROM than the modem was meant for.

[Q] Non textbook problem finding ROM file for GT-P1000

Hi,
I've already been through the thread
[30.03.2012][CF-Root 4.4] J-P/S/Q-*,JV-1KBHIOPQRSTAUV,JVU,JW4 - su+bb+2e/CWM-rfs+ext4
which has links to all the ROM files to be used with CWM in recovery mode (and explanations about their names).
I don't have a standard production phone. Mine has a build name of: FROYO.eng.eunju81.hong.201000831.205407 therefore I can't go by the names of the ROM files which are based on build names like FROYO.xxJP (P obviously referring to "Production"). Does the date of that build have any significance to you experts (Aug 31, 2010)? Does this narrow down what ROM file I can download?
Also, my phone is a pretty standard 512MB, ARM processor phone for that era (I'm guessing, since it was given to a journalist for review who gave it to me when she was done reviewing it).Will I have to use ODIN to flash it? I WAS able to root it (the Chinese made Eroot succeeded where all else failed) and install ROM Manager AND CWM but I then downloaded all three ROM types for my phone (the phone part isn't active I only use the WIFI so I tried the Galaxy Tab ATT, T-Mobile and Verizon but they all gave errors when I tried installing them). I read that it's imperative to have the right file, but with my funky build number, that doesn't seem possible. Am I going to be able to do with this without "doorstopping" my phone? (sorry. I like "doorstop" better than "brick" .

Wrong forum, this is S2/I9100 Q&A, not Tab Q&A which is here (we have device specific fora).
I've asked mods to move your thread, sit tight until they do.

One other thing;
I forgot to mention: Kies updated the firmware to the latest version if that helps you "axe spurts" figure this puzzle out. Thanks in advance!!! :fingers-crossed:

Is the LG-Firmwares 10Q KDZ Verizon only?

I had an unlocked (formerly from Sprint) LG40 on the last available Android update, which was 9.
I had trouble using Red Pocket's GSMA (ATT) sim, so -- at the direction of the LG official website chat (wtf!!!) -- I tried updating to 10 Q using the instructions that LG provided and the firmware at lg-firmwares.com.
I was able to get 10 Q running on the device, but it will not use the cell or data from either the Red Pocket ATT SIM or a T-Mobile SIM.
Reading a prior post, it sounds like the 10 Q KDZ's on that site may only be for Verizon. Is that right? Is there a way to get this phone on 10 (or higher) and ATT?
Thanks.

Whelp. Looks like I found the answer in the ROMs section:
You'll never find a kdz, they don't make it available. I think Sprint is another carrier that doesn't make it available, but vzw does.
There are bkups of both at&t 9 and 10 people have made available, but you'll have to use qfil or bkerlers edl python to restore it. This is a link to my bkup, use it and one of the previous mentioned utilities to restore.

If anyone knows of either: (A) a ROM I can flash to get ATT working or (B) a place to find a backup of ATT 10 (the link above is dead), please post back?
Thanks.
