[Q] WiFi Not Working after Unlock and Root

I have a PrimoC phone that I unlocked and rooted then I installed TWRP and made a backup. I did not bother connecting to WiFi before doing this, but the phone was showing that it wwas receiving signal from VM. After installing TWRP with Hasoon2000's AIO and making a backup, I went to Settings so I could connect to WiFi and download MSL reader. WiFi is on, but the phone can't find any networks and it is no longer connecting to VM.
Any ideas what's wrong?
Phone is Primo C, CDMA

flash boot. img in bootloader via cmd...

Where can I get that for the stock ROM? I've flashed the boot.img of custom ROMs on other phones, but not stock.

Open up the ROM zip from a stock ROM and pull out the boot.IMG. I'm sure there's some rooted stock ROMs posted in your dev section. Or from a nandroid backup from a stock ROM, if you have one.

or the Sprint one here?

Alright, I flashed the boot.img, but it didn't make a difference. Still no WiFi or connection to VM.

Flashed boot.img a couple of times and rebooted a couple of times. No WiFi or service. What can I do?

Hi, maybe your device has lost It's IMEI. Would you mind posting the first 4 numbers of your imei found in about phone? Thanks.

I don't see an IMEI anywhere... Do you mean IMSI? If so, first 4 digits are 3100
Thanks for the help, I really appreciate it. I ported my number to P+, so I don't have a working phone until I get this to work. I flashed another one of these HTC One Vs last weekend without this problem, so I'm not sure how I ran into it this time...

I recommend using SickKernel for Sense roms. Did you flash a kernel through fastboot yet? And did you flash any module files?

No I didn't flash a kernel through fastboot, nor did I on another HTC One V that worked fine last weekend.
I unlocked the phone with this:
http://forum.xda-developers.com/showthread.php?t=1598964
rooted with this:
http://forum.xda-developers.com/showthread.php?t=1751004
Then I installed TWRP and perm rooted by following Hassoon2000's guide and while using his AIO.
This is the same process I followed last week and it worked fine then. The only difference I can think of this time was I didn't even attempt to connect to WiFi before starting this process.
Thanks for the help.

Someone on another forum gave me a .zip called "Jmz-PrimoC-kernel-ICS-20120820". I flashed the boot.img from it and now the phone boots to the VM loading screen and then turns off and continuously reboots and the process repeats.
EDIT: I flashed the .zip and still have the same problem. I'm wiping the cache, dalvick cache, and doing a factory reset and then restoring a backup.
EDIT 2: Restored the backup, it loaded up the phone normally without the reboot this time. I unlocked the phone and a second later it powered off again and now it's rebooting continuously, but it makes it to the normal screen now before doing so.
Really need a phone for work guys. Please help me.

Alright, I did this on a second phone I got for my wife to try and figure out where I went. I unlocked the bootloader and rooted by following these instructions: http://forum.xda-developers.com/showthread.php?t=1598964
WiFi worked after that and VM bars were showing up.
I then booted into Bootloader and opened Hasoon2000's HTC One V AIO Kit. I clicked on TWRP CDMA 2.1.0 and then clicked 'Flash Recovery'. The recovery flashed successfully.
I then made a backup successfully and rebooted. When I rebooted, I was getting 'No Service' and my WiFi doesn't work either.
I may have actually had WiFi and service after I flashed TWRP, but before I made the backup. I think I did, but I'm not sure. Anyways, all that is above is everything I have done with this phone since taking it out of the box. No idea what's wrong.
Please help.
EDIT: When I scan for WiFi on the 2nd phone, I am now finding my network, but strength is always poor or fair and it won't connect.

If the imei really is lost, you will not have a chance but taking it to the HTC service try flashing cwm instead of twrp, maybe that changes something

How would I know if the IMEI is lost? I just don't see anywhere it would be in the settings under about phone. Can I just flash CWM over TWRP?

I followed this:
http://www.androidauthority.com/one-v-clockworkmod-recovery-6-0-1-2-custom-recovery-115527/
and flashed CWM.
Still no WiFi or service. I don't need service with this phone, but I do need WiFi.
EDIT:
OK, so I am getting WiFi on the 2nd phone, but it's weak. When I'm right next to my router only the circle fills up on the meter and occasionally one bar will with it. Still no service though.

Hi, well I do not know the exact noun for this, but you can see it at settings, about phone, phone-identity. Sort for my bad English sometimes, I'm from Germany
Sent from my awesome HTC One V using Tapatalk 2

Under phone identity I only see Phone Name, Model Number, Device Serial Number, MEID, MEID Decimal, Phone Number, and IMSI. No IMEI. I checked a friend's working HTC One V he got on the CM sale too and he doesn't have an IMEI under phone identity and his phone works fine.
Also, I am now getting WiFi on the 2nd phone, but it's weak. When I'm right next to my router only the circle fills up on the meter and occasionally one bar will with it. Still no service though. When I go up to my room where another HTC One V running AOKP says ~35% signal, this phone drops.
Thanks for helping me.

You do have the back cover on right? Did you root both phones with Hasoons program?
Sent from my HTC One V using xda app-developers app

Strange. I've set the language of my phone to english for testing, and I'm getting this (1st screenshot).
Instead of using About Phone, you could try opening the dialpad and dialing *#06# (star pound zero six pound). Now a text box like in my 2nd screenshot should pop up. Please only tell me the first four digits, because an IMEI is unique and private.
EDIT: zmk76 is right, in the back cover is the antenna built-in, so signal drop without the back cover is normal (I have really heavy signal drops without the back cover)

[Q] Insert Sim to Access Network Service.. IMEI Null

Hey Guys,
I have an AT&T Model SGH-1317 Note 2. For use on other networks, I unlocked the phone using the *#197328640# menu option. However, the phone failed to start the hot spot stating Mobile data was unavailable or Invalid Sim. However, I am able to tether perfectly using the same sim on an another S3 so I was sure its nothing to do with the sim or network operator settings.
I looked up and found XDA website with tons of information. I assumed my phone was locked by AT&T. Hence, I rooted the phone using CF-Auto-Root, backed up complete data using Titanium and using Rom Manager I installed the Crash Aroma 4.1.2 Rom. I wiped the data and cache 3 times as suggested. However, after the boot I am unable to connect to any mobile network. A Click on Mobile Network says "Insert Sim Card to Access Network Services". Dialling for IMEI number prompt a Null.
During Installation I noticed the Crash ROM has overwritten the Radio.. and I am assuming this is were the problem lies. but I leave it you experts.. Request Help!
Sunil.

Am currently on Du - A network in Dubai, UAE. I have been reading more forum information and some suggest that this may be related to the EFS folder getting corrupted which may cause the IMEI number to fail. Some suggest that there are software to rebuild this information by using the IMEI number behind the handset..
I also noted that my phone model has also changed to GT-7100 instead of SGH-1317, Wonder if the Crash ROM was apt?
Would you suggest installing a Jedi Rom specifically built for SGH-1317... or is the damage already done?

Back Online
Since I found no replies.. I had no choice but to give it to the Pros.. I handed my phone day to one of the Unlocking experts at a mobile store… He was confident that his technicians would resolve this. But after 2 Days, they have given up.. He suggested the phone would fetch me US$ 10 if someone used it as a demo unit at a mobile shop..
I was sure this was something to do with the Modem, IMEI and the all important NV folder. I was able to find a Stock ROM for the SGH-1317 and I also found a link at XDA about using EFS pro to change the IMEI.
Using Odin software, I flashed the phone with the stock rom. Unfortunately, there was one error when it tried to communicated on com1. Having no choice, I continued. Restarting got the AT&T style boot but it again froze on the Samsung screen. Dreading the communication error, I restarted several times with no results. Finally I realised if would be due to the cache and user data. I reset the phone to factor settings wiping out the user data and Whola.. The phone sprang back up..
Lessons learnt.. Backup your rom and data before playing with custom roms. Read Read Read and don’t flash in the middle of the night..
Since I am back online, I plan to stick to the stock and crappy 4.1.1 with all the AT&T dead weight. Will live without the ability to Tether until my fingers get warmer.. It won’t be long as I am already bit by the Custom Rom Devil..
Don't Give Up Easy..:good::victory:

Please I am having the very exact same issue and can't seem to have it fixed
Using CMW I also flashed it back to stock rom, didnt have any problem or errors doing it but im still getting No SIM Inserted. I have deleted cache and user data several times... Tried flashing CM10 and CrashRom see if they made a difference and still No Sim Inserted... tried 3 different kernels and still same issue

I have the exact same problem since yesterday. I've tried everything and anything to no avail. I'm very close to returning the phone.
I would really appreciate any input.

Same issue
I flashed crash rom 4.5, over the stock kernel and it gave me that same message. I've tried everything I could think of, which included everything in this thread to no avail... any further advice would be greatly appreciated.

Your username suggests that you have the N7100 device ??
If so. ..you are in the wrong place for support. ..As this is the SGH-I317 section.
If you are showing IMEI NULL with no baseband you may have to restore your backup image to correct the problem. .
If no backup image exists. ..you will need to flash a factory N7100 image from your section.
Look for the return to stock thread for your specific device and that should fix you up...
The CF AUTO ROOT files are device specific. ..so I hope you haven't damaged the partitions.
Good luck. ..g
Edit:
This will help. ..and will place you in the right section. ..
Just go to page 1...good

Sent from my SGH-I747M using xda app-developers app

this is a known issue with AT&T. not only the S3 but HTC's One X and several others as well. i would imagine the problem is based on network location. you could try powering down, removing the battery and sim card for a few minutes and then clearing the data and cache in the phone app once its powered back up. otherwise, give a call to customer service. cheers

Ahh right. I forgot my dad had that when he had the s3 and he traded his phone for an iPhone..lol. I panicked and thought it was because I rooted my phone so I flashed stock with Odin. Guess I'll root it back and backup my efs folder this time lol
Sent from my SGH-I747M using xda app-developers app

I recently experienced the the same issue but with a different rom. I did a clean install, everything booted up and seemed to run exceptionally well. After 30 mins or so I lost my data icon and signal bars disappeared all together. My imei showed 0 along with eri version and serial number. I panicked a little bc I was at work without access to my laptop, booted into recovery and restored a BlackJelly cwm backup. Luckily everything was seemingly normal again after that and going forward has been fine. But a couple of months prior I flashed the wrong recovery.img and completely corrupted the efs folder. None of my cwm backups worked at fixing the imei, eri and serial. Thankfully there is an amazing guide in our development forum that addresses exactly how to fix this.
Sent from my Atat S3 that now thinks its a Galaxy Nexus.....

Those darn s3's haha Lol. I don't get why it seems like restoring a nandroid is temporary but going back to stock with Odin erases the problem. I don't even know what I did wrong while flashing. I basically read how to root then started flashing things.

[Q] Sprint Galaxy Nexus; signal/3G issues

Sprint Galaxy Nexus
4.2.1
Not rooted
I performed a factory reset on my phone yesterday due to it bogging down and being rather slow. I never did a reset after getting the 4.2.1 update so I figured it was a good time. I woke up this morning, putzed around the house, and setup Tasker again. I laid my phone down for ten minutes while I got ready for work. Whenever I tried to wake my phone and nothing happened. I tried a few more times and the screen would not wake up. I pulled the battery, hard reset, reinserted battery and the phone wouldn't turn on. Then, I wiped the contact terminals (on the battery and the phone) and reinserted the battery and the phone booted up. However, since then I have had some major problems.
1. Power button does not always work properly. I have to press it several times to sleep or wake the phone. (Okay, not major, just inconvenient and probably unrelated to the issues below)
2. No data connection whatsoever.
3. In the data usage menu, there is no longer a data toggle switch.
4. Under the Network Mode option, LTE/CDMA produces absolutely no cell signal whatsoever. I have to switch to CDMA only. (WiFi works fine)
5. Toggling airplane mode, as some have suggested, does not cause the phone to connect to mobile data. Another factory reset did not restore mobile data. Rebooting did not restore mobile data.
6. All of these problems are true before and after factory reset. No new problems were created and nothing was exacerbated as a result of performing a factory reset.
I've been from one end of the internet to another looking for solutions to this problem and I have found that many are having a similar issue but toggling airplane mode or rebooting fixes it. Not the case for me. Most also seem to be having this problem after rooting. Again, not the case for me.
Any suggestions? I would prefer to not return the phone. Purchased from Radioshack and the 30-day warranty has expired. This is my second gnex already, as the first one's charging port broke. It took over a week to get this one from another store which graciously shipped it in to my store. There's also the issue of being broke and not really being able to afford another $30 activation fee on top of the deductible for a new phone.

Why not try reflashing the stock image and updating again to 4.2.1?

Not at all. You'd use Odin . Myself I have very spotty sprint signal in my home. Spoke to a corporate executive and they mailed me an AirRave free . Never have less then full bars 3g all around home. You should a- flash to stock using Odin following posts in sprint sextjon . b - call up and try to get an airavana.

Excellent. I will give it a shot at some point today or tomorrow and then let you know how it worked out. Thanks!

So, I restored the phone to stock. Signal is still non-existent on LTE/CDMA mode. Cannot perform Profile or PRL updates. Still no mobile data. I'm guessing hardware failure?
Also, on setup it asks for a SIM card. And at the bottom of the drop-down menu, it says "No SIM card|Sprint" or "No SIM card|No Service" depending on if I am in CDMA or LTE/CDMA.
Also, in the Status menu:
My phone number
Unknown
MIN
Unknown
PRL Version
Unknown
ICCID
Unknown
Seems a little odd to me.
Attempted fully rooting and flashing radios. No luck there either. It's also not wanting to update. Tells me my phone is up-to-date (connected via WiFi). Downloading Cyanogen now to see if it will work in the morning.

And while attempting to flash a new ROM, got the famous "can't copy anything to the device ever, under any circumstances" error.

Update: Got CM10 installed. Still "No SIM" error, no 3G, no data, no LTE. Found some more information on this No SIM error. Apparently a few others have had this same problem and in the end had to get a new phone.
Anyone know anything?

You should a- flash to stock using Odin following posts in sprint sextjon

I've been back to stock twice now. The first thing I did was flash to stock. Then I played around a bit and now I'm back to stock again.
Is there a difference between using Odin and Nexus Root Toolkit to return to stock?

Bump

Wow, one day and my thread is buried!
After battling for about a day, I got updated to JB 4.2.1, I can do profile and PRL updates again, but there is still no 3G/mobile data, and I still have zero bars on LTE/CDMA and have to use just CDMA. I am currently stock but the bootloader is unlocked, no root.
If anyone has heard any solution, please help. Also, if there's a difference between flashing to stock with Odin vs NRT, please say so.

Try fastboot flashing your LTE and CDMA radios again. As far as I know, fastboot commands do NOT require root. I had a similar issue.
Edit: link to post with directions http://forum.xda-developers.com/showthread.php?p=39446679
Sent from my R2-D2 unit on the far side of the moon

Indeed, fastboot does not require root. I've flashed my radios several times now in various different ways. I even flashed different versions. I attempted again but with no luck. I have normal service when using CDMA but nothing on LTE/CDMA. Still no data, still "No SIM card" error.
Pretty sure I'll have to get it replaced. I've gone from stock JB back to stock ICS, rooted, CM10, back to stock ICS, rooted, back to stock JB unrooted, and flashed three different radios. I'm surprised I haven't managed to brick it yet.

UPDATE: Sprint is sending me a new phone, for free.

Radio issues with 4.2 Roms

Hi all, I am again posting about having radio issues. (NO T-Mobile signal) Any 4.2 Rom I try to install, I am unable to obtain phone service. (signal)
Here is what I did:
1. Start from scratch, total erased phone and sd card and micro card.
2. Odin flash stock Rom and Odin flash latest TWRP
3. Copy Rom to SD card and flash. (flash is fine)
4. No signal, flashed newest UVM6 radio, all kind of wipes.
My phone is SGH-T989 T-Mobile. I even changed the APN, but still only pick up AT&T which still having no signal bars. I tried flashing all radios available with no help at all. I am able to use certain 4.1.2 Roms such as Infamous 3. I even tried different kernels, different wipes and just can not get any T-Mobile signal service. I have tried searching for any and all radio issues for this phone. NOTHING works for me. Can anyone or does anyone have same problem that came up with a solution to get a signal for T-Mobile for these Roms? I am currently using the Infamous 3 Rom using Arc kernel. Actually the only other Rom I can use it the stock deodexed rooted base. Very frustrated not being able to use these great looking Roms, HELP please! Thanks for any information or solution. BTW, I have tried everthing and every type of wipe to no avail.

do you still have your IMEI or does it shows blank and unknown ??

I am having the same issue. It does show my imei # though. How do I fix this?

Oh boy.....again.
K....here is about everything. If none of this is your problem, since you say you've checked everything....and yes, I have read your other thread....in which you repeatedly say you tried everything, then you have a hardware issue, or are simply doing something wrong and telling us you did it right.
Not getting a signal.....
- not using latest T-Mobile or Telus radio. Maybe you flashed it, but is it actually showing as that radio in settings??
- APN settings are wrong or don't exist. Lets pause here. You said you checked apn and only pick up at&t. Or am I misreading that. If you don't have the correct T-Mobile apn settings, then you wont get a signal or data. Period. This has to be correct before bothering with anything else. You said you checked. Against what?? I've seen plenty of apn settings when Googling it, some simply don't work. Maybe they are old settings, wrong phone, whatever. I'm Telus, so can't help you with the settings for T-Mobile.
- what has already been posted above needs to be correct.
- maybe radio file you flashed was wrong one or corrupt. Perhaps try the Telus one. Should work too. Since T-Mobile radio works on Telus.
- restoring any system data after a flash? Huge no no.
- wrong mobile band selected?
- and a possibility .....simply no signal where you are. Or it's a weak signal, and your assuming it doesn't work?? Ignore this if you have a very strong signal usually where you live. 4.1.2 to 4.2.2 shouldn't affect signal much if any.
Anyway.....that's about all there is to it if you are CLEAN flashing roms and following instructions to the letter. I am confident you will say all the above is good....and if so....I am afraid you will probably find no answers like your other thread. Meaning you have an extremely rare issue. Or a wierd hardware issue, sim card maybe....tho before you dismissed that as a cause. Another possibility is that you aren't correct when you say apn is fine, or the radio you flashed is fine. Not accusing you of misleading anyone, just saying perhaps you are innocently wrong when you tell us this or that is fine when it is not.. I've done tech support.....happens all the time! !!
So, good luck. Hope you find a solution ......tho this is your second thread on same issue....so you may have some rare issue....and may be boned.

He's got something wrong for sure. Or he's got a strange phone that won't work with 4.2. And I doubt that very much.
He's got wrong radio, or wrong or missing APN settings.
Or wrong phone, sim or carrier.

- and a possibility .....simply no signal where you are. Or it's a weak signal, and your assuming it doesn't work?? Ignore this if you have a very strong signal usually where you live. 4.1.2 to 4.2.2 shouldn't affect signal much if any.
Anyway.....that's about all there is to it if you are CLEAN flashing roms and following instructions to the letter. I am confident you will say all the above is good....and if so....I am afraid you will probably find no answers like your other thread. Meaning you have an extremely rare issue. Or a wierd hardware issue, sim card maybe....tho before you dismissed that as a cause. Another possibility is that you aren't correct when you say apn is fine, or the radio you flashed is fine. Not accusing you of misleading anyone, just saying perhaps you are innocently wrong when you tell us this or that is fine when it is not.. I've done tech support.....happens all the time! !!
So, good luck. Hope you find a solution ......tho this is your second thread on same issue....so you may have some rare issue....and may be boned.

Thanks for helping and I think your right about being boned or hardware issue. I have tried different downloads of radios, both Telius and Tmobile and copied APN settings from working stock Rom. Maybe bad Sim, anyway I will have to stay with what I have until I get new phone, which is soon. Thanks again!

Stumbled across this. I've never heard of this particular issue before, but sure sounds the same as your issue. Try this fix if you haven't already.

i had this problem with slim too. i thought something went wrong with my phone or my area. but nope. what you need to do is go to mikeyman777 cm10.1 thread and find the uvmc6 tar file, then use odin to flash it. apparently just flashing the newest radio with twrp isn't enough because it's missing some files or something like that lol.
anyways i haven't had signal problems since flashing radio tar file. i've lost signal like once. before i was losing it everyday. hope this helps.
