Buy HTC Vogue Clean ESN CDMA Set to eaby.com . & how to Use This Phone In India in CDMA Network. pls tell
I m read another Indian forum. HTC 6800/6900 convert to tata CDMA
here is detail
SID, NID, Primay Channer A & B, Secondary Channel A & B loaded Nam 1 & Nam 2 PRL, SPC = 000000
I got all above Parameter from Tata Customer Care and they told any Foreign ESN Handset can work if you are able to change the above Parameters, After that I Get an GSK (Getting Started Kit) of Tata which have 14 Digit Activation Number, then Dialed *228 and followed the Instruction, After 2 Hours (Tipical 10 Minutes they say) Received a SMS to Restart the Phone. Voila my HTC Mogul is Working on TATA
Will load my QPST .qct file (Ready made Setting for TATA) so every buddy can easily Activate Mogul on TATA
Everybody now Welcome to World of Tata Indicom
( Attached TATA.rar contains Nam1 PRL, Nam2 PRL, and Ready made QCN file for QPST Service Programming, also have GetSPC [ Run in PPC6800 / Mogul Type the ESN in Capital and get the Service Programming Code] )
Pls Help me

Sounds interesting but I'm just wondering
OK.... can u explore more on that.
How does one go about creating/editing the PRL settings contained here if they want to use this thing on a different network than Tata?
thx

This method work on Cricket in USA and in TATA in India
Just follow the Process and Activate using *228 Loading TATA Prl is needed or else it will not catch TATA Tower range.
Go on and take it into TATA
I already have activated so many Phones
Both Cricket and TATA accept non Allocated ESN and Activate the OTA and INsert the new ESN against users Services, Here in India Reliance dont activate any phone which ESN is not pre Registered in Reliance Network

I was wondering if this will solve my issue. I have bought a touch with a bad ESN and is unable to put it on my account. Will this clear the ESN?

I used this ..so easy

so if you activated your phone for india service, would you be able to use it in the United States?

I did this for my Sprint Touch. I am still using it in the USA but my phone has been modified to support other carriers with no problem.
The steps are simple:
Here is what you need to do:
1. Download GetSPC(attached below)
2. Unzip to desktop
3. Turn off phone and remove battery.
4. Write down your HEX ESN
5. Power your device back on
6. Connect via ActiveSync or WMDC
7. Copy entire folder to main memory on device.
8. Run GetSPC.exe
9. In the top box type in your HEX ESN(make sure caps is on)
10. Click generate or whatever the button is named
11. The resulting number should be a 6 digit number, your MSL, write it down.
12. Search for, download and install Qualcomm's QPST tool.(not freeware)
THE FOLLOWING STEPS ARE VERY DANGEROUS SO MAKE SURE YOU FOLLOW MY DIRECTIONS EXACTLY.
13. Run QPST Configuration(run as admin if Vista)
14. From the Dialpad, dial ##3424#(##diag#)
15. Connect device to computer via USB(this will install drivers)
16. In QPST Configuration, click ports.
17. Continue to add ports until the QPST Configuration detects your phone
18. Under active phones it should display your phone.
19. Click Start Clients/Service Programming
20. Select phone and click ok.
DO NOT LEAVE FIRST TAB, THE SETTINGS TAB. THIS IS THE ONLY TAB WE WILL NEED TO CHANGE ANY SETTINGS
21. Under the settings tab, click Read from phone.
22. Input your MSL you got from GetSPC earlier.
23. Under codes where it says Service Programming, change this to 000000
24. Click Write to Phone
25. Wait 1 minute
26. Close Qualcomm QPST one window at a time.
27. Disconnect the USB cable from your device
28. Perform Soft reset once
29. Test new MSL(##000000#)
30. If new code does not go through, hard reset.
31. Depending on what device you have, follow the necessary steps to unlock your phone so you can flash a new ROM to it.
32. Install OEM ROM from carrier of choice or build your own custom ROM using the new carrier's information.
33. Follow instructions to flash new OS to device.
34. Call service provider and do some sweet talking to get them to activate the phone on their network. You may need to do some serious sweet talking because Sprint ESNs are not in Verizon's database and vice versa. This goes for all CDMA carriers.
Good luck.

are u then able to have both NAM1 & NAM2 on the phone?

NAM
You have to enable dual NAMs through the registry. And use QPST or CDMA Workshop to set them up.

Thanks a million time to Shadomite
He had Cracked and changed the ESN
I have POsted the Simplified Method Just have a look

Need English Viva ROM for Vogue (MP6900SP)
Thank you for this great post. I followed the instructions without bricking my phone. I looked at the 'simpler' one linked to here, but found the one on this thread much easier to follow and use.
Now all I need is the ROM for Viva (North America or Carribbean). Where can I find this? Thanks,
WMT

Hey Hetal
can't find your post on mobile-files.com. Is there any other link.
Will this method work on reliance network too???
Thanks

[Q] Sprint TP2 on Tmobile (Android) Radio Problems

Alright, so I have a Sprint CDMA Touch Pro 2, security unlocked, and flashed with the world unlocked radio. Everything in windows mobile works great on tmobile, however when i boot into android (Froyo X) from SD card i am unable to access anything. I'm assuming android is using the CDMA radio, and I cannot find any options etc to change it to GSM, or enable world phone mode.
So, it this possible? When i search for the network, it will find Cingular and Voicestream Wire. It will only do this once, and if I attempt to search again at any time without rebooting first, the entire system will freeze, and requires a hard reset.
I do have a 3G indicator, and signal bars which change periodically, but I am unable to connect to anything.
I've done several forum searches, as well as looked through all the settings I could find.
Any help with this would be awesome!

You need to check two things in your Startup.txt file. The first is that you should have your model number in the following field instead of the "rhod100_uk."
Code:
physkeyboard=rhod100_uk
The second thing is that you need to set the following line based on whether you use your device on a GSM network or a CDMA one. If you use it with a CDMA network then change the "0" to a "1." If it is used on a GSM network then leave it as a "0."
Code:
force_cdma=0
Depending on how you installed Android, the startup.txt will normally be in either the root of the SD card or in the \andboot folder on the SD card.

Enable AWS band (3g/4g Tmobile) on ATT Note 2 stock baseband

Method 1:
Easiest method to enable AWS and DC HSPA (42Mbps) is to restore the attached qcn backup on ATT note 2. Use software download tool in QPST to restore the attached qcn file.
Restoring qcn will not change your imei, so be worry free and restore Thanks to TEKHD for sharing the T889 qcn backup.
If you face issues with data rate and stability, restore your device original qcn on top and change the value of 01877 to 115868544 in NV browser of QXDM or use 80 03 E8 06 in the text file and write it to device. DC HSPA or 42 Mbps will be disabled after this
Thanks to Arrio for helping me remove imei from qcn file. I have attached my note 2 qcn backup.
Now it should be piece of cake for all
How to posted by Joogle
1. Download and Install QPST, version 2.7 build 374 or higher
2. Go to hidden menu on phone, dial *#7284#
3. Once in Menu choose the option for USBSettingsMenu, then choose the option RNDIS+DM+MODEM.
4. Hook up the phone to the PC via USB at this time if you haven't already. This option works on STOCK TOUCHWIZ.
5. Go to your PC Control Panel. We need to get into the Device Manager to determine where your phone is being recognized as far as the COM ports. For this, go to System -> Device Manager (on the left) or System -> Hardware -> Device Manager (depends on your Control Panel setup). Anyways, scroll down to Ports (may say Ports & LTP, Serial, depends on version). Anyways, find your phone under it, and take note of the COM# (mine was COM9, yours can and probably will vary). If you have exclamation marks anywhere then install the Samsung drivers and try again.
6. Now go to Start Menu -> All Programs -> QPST -> QPST Configuration
7. Click on the Ports tab. Click on Add New Port, then add your Port# where it says Port and name it something you can remember. Hit OK.
8. Now click on Start Clients -> Software Download. Click on the Backup tab. Make sure your phone is listed under Port. If its not, hit Browse, choose the COM that is your phone, and hit OK. Now where it says QCN File, hit Browse, find a safe spot to store your backup on your PC, and name it. Hit OK. Now hit Start. Make sure backup gets to 100% with no errors.
9. Go back into QPST. Go to Start Clients -> Software Download. Click on the Restore tab. Make sure your phone is listed under Port. If not, browse to the appropriate COM port.
10. Choose the QCN backup in the first post of this thread. Click Start, let it finish. Phone should reboot. If it fails rebooting, just do a manual reboot. First boot will take a bit, let it do its thing.
Messing with NV parameters can brick your device.

Does that mean if we enable NV's (which basically enables AWS), we wont be able to disable AWS and go back to At&t GSM or ? Or once we enable NV we can use both at&t and T-Mobile Sims?
Also have you tested this method with T-Mobile SIM? High data speed, low data speed?
I would love to be able to use my Note with AWS band network (Wind mobile in Canada), but instructions are way beyond my understanding :laugh:. Will wait for easier instructions if they get posted.
Thanks for your work.

That's as easy as it gets, and yes it will unlock those bands permanently along side the AT&T bands.

Follow up Qs
1) Thank you so much for posting how to do this.
2) Yeah, I second ruinkhan; Do you know if AWS is still 21mbps or 42mbps like the T889?
3) Is enabling AWS on the N7100 or N7105 possible? How about on CDMA models with SIM slots and GSM support unlocked (such as Verizon i605 or US Cellular R950)?

Use of AWS can be disabled by changing one of the NV item, but all enabled parameters remain active. This does not cause any problem with the device working. It would work as any stock ATT note 2.
Yes you can use any SIM or network that support these radio bands (UMTS 1,2,4,5 and Quad band GSM)
I am using a T-Mobile sim and I do get around 8 Mbps download speed and 3 to 4 Mbps upload.
Ya I agree the instruction are bit complicated

I am working on 42 Mbps, with the posted NV backup, even 42 Mbps NV items are included. My note 2 does inform network about 42 Mbps support when enabled but I dont see any change in download speed. I guess the network does not like something.
Yes it should be possible on N7100 or N7105, as all have the same Qualcomm 9215 baseband chip. But I am not sure if they have the right RF related hardware.

the instructions for nv backup says to select rmnet+dm+modem. i do not see that option in there. are you suppose to choose a different option for the note 2? any issues of doing this on a canadian i317m?
thanks

On my ATT Note 2 I can see that option, what options do you see?

I will do this tonight with my I317, can anyone post a more clear set of instructions? I already have the T-Mobile ROM posted on the AT&T dev section as well as the AT&T ROM on T-Mobile's dev section... This is a huge discovery... I mean huge... Please, anyone care to elaborate on this... Better instructions... I have both the T889 and the I317... And I will test this as soon as there is a better guide... Thank you

Indeed this a huge plus for our At&t Note. I wasnt expecting this to be done this early, but the man did it. My hands are now itching to try this and save $50 a month by switching to AWS network. I would really love to see easier instructions [not all of us hackers ]

Yes you can select any mode with DM (Diag mode) which enables the diagnostic port to the baseband.

It allows people that have At&t Note 2 to use their device with T-Mobile's 1700 frequency band (or 2100 if there is).
In Canada its a big big plus as it allows people like me to be:
1.Free from 3 year contract
2.Have a GSM phone that can be used with AWS network as well.
3.Get a $40 Unlimited Voice/Text/Unlimited Data (10 data cap lol) plan. Of course No LTE or 42mbps speeds.

sjravi, perhaps these NV backups would be of interest for comparison purposes. I got these in the course of trying to flash back the stock modem on my T889V, which it currently bootloops with.
My phone is currently stuck with the I317M modem, has 850, 1900 and AWS HSPA in addition to LTE. Barring any inaccuracies in the Ookla Speedtest app, it also has DC-HSPA. (The phone clocked at 26 Mbps on HSPA during one of my tests.)
There's a stock T-Mobile T889, stock Videotron T889V and my post-repair, I317M modem-running T889V backup in there.

is there list? as in what lines to change?

Things needed:
1> NV back up tool from this post: http://forum.xda-developers.com/showthread.php?t=1804117
2> NV backup from my note 2 attached in this post (without IMEI: nv item 550)
3> NV backup of your device
Its also good to take NV backup using QPST tool before changing anything on the device.
First take a NV backup of your device using the tool mentioned above. NV parameters from 0 to 7225 are needed.
Compare NV param file in this post with your device's to find the needed NV parameters for AWS.( I do not have original NV backup of my device else I would have posted the list. If someone is interested to make a list, it can be added to the post.)
Before restoring nv backup, the AWS NV parameters should to be enabled/B]
The additional NV's that are needed, to enable AWS band are disable/not present and the nv tool does not write these even if the restore file has them. This is what I noticed when I tried to restore. So had to enable all the required parameters using NV browser in QXDM.
Once the NV's are enabled, it cannot be disabled so be careful.
To enable just select the NV item and click write in NV browser and this has to be done for all the needed nv parameters.
Does anybody know a work around to avoid this manual work?
Once all the parameters are enabled the NV file in this post can be restored on to your device to enable AWS.
Messing with NV parameters can brick your device.

NV manager is very old tool and not supported by note 2, so you cannot use it.
Use NV browser in QXDM (last version found online 3.12.724), which you can google to get it.
Once you have installed it. Run QXDM professional
Go to Options > Communications: Here you should see 2 ports for the phone one is modem port and the other diagnostic port.
Select diagnostic port. Check out the attached screenshots
After you have the NV browser open. Select the NV item that needs to be enabled and click "write" this will write the value "0". Hope this helps.

p607t lte/wcdma not working

I have received a p607t tablet, it was flashed by smb. to p905 firmare (with no imei). i re-flashed it with stock P607TUVUBOI2 firmware (4 files, so-called "service" firmare), imei is back (to what is printed at the back-side) but mobile networking *still* doesn't work: no connection. I'm using not t-mo sim-card, but looks like the tablet was already unlocked
From service menu *#0011#:
SERVICE : LIMITED
NETWORK : UNBLOCK
IMEI Certi: PASS, 1
From Advanced Signal Status:
Carrier:
Network Type: Unknown
Signal info: n/a
Neighboring CID: no neighboring cells --- wtf? >> other devices work ok with this sim in lte and 3g modes<<
GSM service: emergency calls only
GPRS service: disabled
Any ideas?

OK, so, what is done with p607t to the moment:
1) reflashed CP (modem/RF??) to latest stock (P607TUVUBOI2)
2) reflashed AP/PDA (core system??) and CSC (consumer stuff??) to P605XXU1EOI5 (from p605, have one right here - it never had network-lock from factory)
3) using qpst and qxdm changed nv parameters (extended lte bands, enabled gsm rf-bands - there were none in stock at all, only wcdma)
now the tablet sees my local gsm network with this sim-card, signal is 4/5 bars, but still no internet connection - WTF??
p.s. when trying manually to register in my local network - it fails with "try again later"
p.p.s.: what is i find weird, in service menu *#0011#:
NETWORK : UNBLOCK
- this line exists only on p607 - is this the key?
Then, i insert this sim into p605 (completely stock P605XXU1EOI5) - it works like a charm
need some help - where to dig next? point direction plz

UPDATE. i've been tweaking 607t nv items with qxdm, making it alike that ones 605 has. practically everything is alike now, but still it doesn't even try to establish data connection with cell...((
btw, 605 does not have "esf embedded file system", while 607t has one (can be seen through qpst-esf explorer)
also, some nv-items present in one model, some present in another

I had to flash back to the original kitkat firmware and take OTA to upgrade to lollipop. There is a known issue with the 607t losing data after roms are flashed. Some had luck with flashing the same rom twice but it never worked for me. Used Sam mobile to pull original and went from there. Good luck

I performed "device init and reflash" with Keis. The device is back to stock completely, except:
- nv items data
- esf embedded file system data
so... my guess - i need to restore these in order to have mobile networking working.
could someone post a qcn-file with factory esf-data?

ok, let's take another way: how can i get some gsm-module debug-output or log to understand, what's going on it?

i'm trying to write some custom modem.bin to /dev/block/mmcblk0p2, but after reboot data in there is reverted to stock modem.bin - how come?? is that bootloader doing? where is the stock-one stored?

cannot get LTE communication with S4mini plus (i9195i)

Hello
Here is my issue: I buy a second hand S4 mini plus (i9195i - serrannoveltexx) for its compact size and by considering the simple usage I make of my phone. So far I do not use so much data so I don't care about used network, but recently I start using more data and I notice I never get LTE. I change carrier because I was thinking LTE-cover was the problem, but not. I still have no LTE. So below, is more or less everything I tested:
at beginning, I was few months on stockrom. Then I go to LineageOs 14.1 (thank to dev for the work). In both case I'm almost sure I had no LTE (I checked APN and 4g/3g/2g enable in network menu. And I start to check LTE-cover of each carrier . And I very start to check band used by the different carrier).
I change carrier and I check APN once more : still no LTE.
I come back to stockrom (just in case) : still no LTE
I switch SIM card : my sim card in Oneplus One get LTE and sim-card of my friend do not get LTE with my phone. (So I try copying manually the exact same APN : not working)
I try to flash old stockrom and let OTA update make the work : no LTE
I make necessary to have CSC=XEF as I am in France.
I try flash with pit-file and re-partition.
At the end, the best thing I succes to get was H+ (and for some reason I have it when I clear and restore the NV in 'service menu'), so :
-I contact samsung and they recommend me to go to one of their after-sales office.
-I contact my seller and he tells me that LTE works in germany.
Does someone has an idea how to solve this issue ? something that could block LTE ?
Next step I have in mind :
-I read some topic where double-flash within wipe and clear factory could help (but I have the feeling that will not work because it is more or less what have done to change CSC)
-I would check the activated LTE bands (but in 'service menu', I find a LTE band hexa-value that meet with explanation of binary description (another thread in XDA - thanks to people who write this tuto))
-I am considering go back to LineageOS but 15.
-I am considering to change LTE antenna (this is part of middle frame - I notice if I enable Data when i have 'service menu' opened, the phone seems to looking for LTE first, so I am not sure this is only SW problem ... do you think it is possible that only LTE part of such a SystemOnChip could die ?)
Thank by advance for your help
Best regards

Hello
Here is my issue: I buy a second hand S4 mini plus (i9195i - serrannoveltexx) for its compact size and by considering the simple usage I make of my phone. So far I do not use so much data so I don't care about used network, but recently I start using more data and I notice I never get LTE. I change carrier because I was thinking LTE-cover was the problem, but not. I still have no LTE. So below, is more or less everything I tested:

Some older Samsungs eg Note 1 had reception problems due to poor connection (possibly oxidised contacts) that could be fixed by simply tightening the screw a fraction that secures the pcb or antenna so it was grounded (from memory) properly, though of course it could be your actual antenna that has failed. (possible cleaning contacts might be worth a shot if tweaking screw doesn't fix)
(or modem/baseband issue if software, try flash again or try another version, backup your baseband radio settings first with twrp or an app)
edit: also try reset network settings before paying for new antenna (edit: though suppose flash with pit etc should have done this)

Hello,
Some news on the topic:
I try to tighten the screw and I also try to clean LTE antenna contacts : I use very very thin sandpaper (usually used to polish) to be sure there is no oxidation
I also make the mistake to erase all EFSs and EFS_Backup
Reminder : in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'NV backup test' / 'Erase all EFS 1/2/3' => So never do this if you have no backup
After this, I lost my IMEI... no way to restore it with IMEI tool... What a pity because I was hoping to only set my IMEI in order to test with completely clear EFS. Finally I restore my IMEI thank to my very first TWRP backup (thank to TWRP team that it works for me because it seems not always the case)
I try 3 times consecutive reset factory : 2 in recovery and 1 in settings.
I try to activate new LTE band but it seems that as I am in StockRom, update is not properly done.
In fact just after the work with QSPT and QXDM, I can find the nez band in service menu (*#0011#), then 'UE Setting & Info' / 'Setting' / 'System' / 'LTE band & CA combination. but after reboot I lose it. Probably I'll make the work one more time after coming back to LineageOS.
One last thing I want to try is going in front of 4G antenna and check signal power seen by the phone but I'm thinking this is not the true problem. I explain:
service menu (*#0011#) start to show Basic network information and if I force LTE_only (in service menu), I can observe these information. strange thing I see are sometime state goes to 'TAU_init' (and also 'deregistr' or 'register'). Some other time MCC-MNC goes to 151515-1515. I have the feeling the phone is trying to connect but something goes wrong and I do not know what...
if someone has an idea, I am still looking for.
Best regards
