LOS Workaround

Found this workaround to a problem many users are having with LOS then not reacquiring. Simply put the phone in airplane mode, open the task manager (long press home), go to RAM and clear the memory, take the phone out of airplane mode and it should now be good to go. This or reboots will have to do until a fix is released
Just airplane doesn't fix the issue and rebooting is a drag since apps and everything need to be restarted.

I had this issue since day one of flashing Max's kernel so after a week and a couple kernel changes and even a flash to StarBurt ROM i finally got my phone to stay connected.
I flashed back to stock kernel. After resetting I pulled the battery for about a half minute then once it connected again I did the ##72786# and reset the phone again. Make sure you have your MSL number for that. Once I had connection I then updated the profile. rebooted After it reset I found I still have root, still have Starburt ROM and have stock kernel and no more LOS on either Wifi or network. For a week I couldnt keep a signal on either one and it was frustrating trying to use the phone to upload or use Nav. Its been about 4 hours now and I have yet to loose anything so maybe this can help someone else who is in the same boat.

Could you confirm that this is still working?

Ive had it running for about 8 hrs now and havent had a loss of signal on Wifi or 3G. When I was having issues with Wifi, the wifi signal would only be 1 or 2 bars. Now I have all bars in WiFi and no issues as of yet. Using 3g has been good to but in my area I usually only get 3 bars so so far so good.

I had the los just after I flashed max's kernel too but flashed the stock kernel and then rooted, then updated the profile and rebooted. So far no los for two days

[Q] Data and Phone network connectivity problem

My Verizon GN is having difficulty connecting to my phone and data networks. It all started on the day of the outage this week. I assumed it would all fix itself, but it has not. I've snooped around the board quite a bit and it seems all other users have had their connections restored.
I first noticed the problem on Thursday morning. My data status in notification bar would drop to display no "bars." It does not switch over to 3G. I figured this problem would resolve itself once Verizon fixed its network.
Then I tried to send a text and it couldn't be sent. I tried to call someone and it would not dial out.
But these loss of connections are not persistent. Eventually, the 4G works for a bit then disconnects again.
The phone network seems to be doing this as well. Sometimes I can call/text, other times I can't.
I was considering wiping my phone and flashing a new ROM or getting the stock ROM from google to flash. However, I seem to be having trouble with clockwork mod. When I try to reboot into recovery mode it takes me to what I assume is download mode (shows an android knocked over on his side with, I think, a red X).
Is there something simple I can do to fix my data/phone network connection?
If I have to flash back to complete stock, then how do I do this without being able to access recovery?
If all else fails, will I be able to do a factory reset considering the current scenario? I assume I would need to do this before bringing it to Verizon for service.
I appreciate any help provided. Here are some other details that might help.
Rooted with stock ROM
4.0.2
Baseband I515.09 V.EK05 / I515.EK02
Kernel 3.0.8-gaaa2611
Build ICL53F
/edit/
I should have mentioned I had the most up-to-date version of CWM. I just reflashed it with ROM Mgr and it booted into recovery, so that's good.
Well ****. I went into CWM - Advanced - Fix Permissions. I thought hitting Fix Permissions would bring up another menu. Instead it fixed permissions. Hopefully I didn't do something stupid that I don't understand.

I flashed the GummyNex Rom hoping it was a kernel issue or an issue resolved by going from 4.0.2 to 4.0.3. It's been a little better it seems, but it did drop both networks once already and it's only been 15 minutes or so.

The new ROM definitely did not solve anything. I don't know what to do. I need to find a way to get back unrooted, unlocked, stock. Unfortunately, I'm running Mac OS X 10.4.11 which current SDK doesn't seem to support.

[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.

[Q] Lost IMEI now stuck in boot loop after ODIN to stock

Hello,
I'm having a lot of difficulty getting my Note II (SGH T889V) in working order . I'll try to explain the situation in an organized way. Thank you for your time and kind help!
Background
I have a Note 2 from Wind Mobile in Canada - SGH T889V. I got it 2.5 months ago. It was rooted, was running TWRP and I only loaded one ROM, flashed once, on it - 4.1.2 modified touchwiz ROM. Never once had an issue. The ROM was super stable and in great working order.
I got it unlocked about 2 weeks ago because I was visiting the states. When I got to the states, I put in a T-Mobile sim card which was working great for a few days. One afternoon during my vacation I was having slow data issues, so I thought to change the modem/radio from a Wind Mobile radio to a T-Mobile radio. That gave me 4G data speeds but killed my calls. So I tried to go back to the Wind Radio and that had my phone complaining that there was no SIM card. I went back to the T-Mobile radio and I got calling back but only 2G data.
My IMEI was corrupted - it showed up as zero. I left the T-Mobile radio on the phone when I got back. My home network wouldn't recognize me and thought I was still roaming.
Attempted Fixes
Tried a basic factory reset. Tried a different ROM. Tried wiping all internal data.
I got home and tried to flash to stock ROMs found on XDA for Wind Mobile phones. That didn't solve the issue. The IMEI remained null. The phone would reboot automatically every few minutes unless I turned Airplane Mode on. I figure the phone was looking for a signal and couldn't because of the IMEI problem.
So I looked around on the net and found a link about injecting the IMEI back using QPST (http://forum.xda-developers.com/showthread.php?t=1206275) but I couldn't get the program to detect my phone so I gave up and thought I could just get my binary count to 0 and stock and I'll just take it back for warranty.
I tried Triangle Away but I couldn't get the counter to go to 0 even with stock ROM and recovery. So I thought I would take it to a cell repair shop locally. I took it there and all they did was cause an issue on the phone to make it appear that KIES firmware upgrade failed so that it would be repaired under warranty. You would see a emergency firmware upgrade error the minute you turned the phone on. However, download mode still showed the custom binary count at 1, they didn't get it down to 0.
I spoke with my carrier and with Samsung anonymously, they said the counter would be an issue if I sent it in.
I came back home and tried doing the following, with the hopes of trying Triangle Away again:
1. Installed TWRP via ODIN and ran the restore on the backup I created in TWRP when I first got the phone. I restored everything including EFS. Phone boots to the stock samsung rom but it would restart automatically every few minutes. Even with Airplane mode on, it would still reboot on it's own.
The KIES error message doesn't appear anymore.
2. Went back to ODIN. It was getting stuck on SYSTEM in ODIN version 3.07 when flashing a stock rom. So I switched the USB port on my computer and used ODIN 3.04 then the flashes went through properly with no hang ups.
So I tried to flash a prerooted (http://forum.xda-developers.com/showthread.php?t=1975560&highlight=wind) stock ROM
and
also a basic stock ROM (http://forum.xda-developers.com/showthread.php?t=2061031), along with a stock recovery
Both just get stuck in a bootloop. I tried going to the stock recovery and wiping data, cache, factory reset several times. No luck - still boot loops. Wont go into the ROM.
I did not try "Re-partition" in ODIN. I'm not sure if that'll hard brick the device but maybe that way I can repair all of the partitions? - http://forum.xda-developers.com/showthread.php?t=860432&page=2
__________
Im hoping to get back into a prerooted ROM or stock ROM to try this Triangle Away Method - http://forum.xda-developers.com/showthread.php?t=2272966 to get the custom binary down to zero.
I tried to use the Triangle Away ODIN method but it doesnt go through in ODIN, it just gets stuck.
If I can get into the ROM without it boot looping or rebooting automatically- I think I can fix my IMEI like this person did - http://forum.xda-developers.com/showthread.php?t=2145967
Outcomes Im hoping for
To stop the bootlooping/ automatic reboots, then
1. To get the custom Binary count to 0 so I can send it back in for warranty to Samsung or my carrier, Wind Mobile. The binary says Samsung Official. - http://forum.xda-developers.com/showthread.php?t=2068156
or
2. To get the phone to working order so I can try this persons method - http://forum.xda-developers.com/showthread.php?t=2145967
The phone is still responding and it's still working with ODIN. It makes me think the issue is software or partition related and not hardware related per se. If it is hardware, I just want to get this phone back to Samsung but I need to unroot/clear the binary counter.
The phone has never been dropped or damaged physically. I've really babied the phone. This is my third Samsung Galaxy phone (I've had a Vibrant and S2x before this one.)
This has really ruined my week. I need my phone for work. I greatly appreciate any kind help or guidance. I know the collective genius here at XDA will be able to find a solution.
Thank you so much!

If you have flashed the tmobile modem you will now have to keep the tmobile one in order to get your phone to boot. Flashing a t889v modem will cause loops. Dont know of any way to get back to t889v modems.

Hey, don't worry, you aren't the first to experience this problem. Many users have reported that the T889V will bootloop with the T889V modem after flashing another modem. Many have also restored IMEI and service to their phones, so there is a solution. I don't have the specifics, but there are many threads about this problem with solutions. I have quickly searched for one and I believe it has everything you need to fix it.

Thank you. I'm going to give that a shot. I'll install CWM then install a T889 TMobile Radio to see if it boots.
I'll report back. Fingers crossed.

Thank you all!
I got the boot loops to stop by flashing CWM recovery, then flashing a TMobile Radio.
From there, I followed the QPST instructions of installing a QCN file on the phone to reenable the AWS spectrum. Then I used the IMEI creator and NV Writer programs and I was back.
Data seems alright, getting alright speeds on Wind right now. I just found my bluetooth a little hard to hear in the car this morning.
So with this process, I should stick with a Tmobile radio from now on right? If I flash a Wind/ T889V modem it'll boot loop?
Have you guys noticed any signal or performance issues after restoring the phone this way? I'm wondering if it's worth the trouble to get the custom binary counter to clear and return this phone for warranty. Seems to be working for the most part so far.
Thank you so much again! I thought I was going to have to pay $100 to get it JTAGed.

Glad to here your back and running.
I have a t889v using it on telus, and since I am stuck on tmobile modem I get lower phone signal but never loose signal. On a plus I now get lte speeds.

First day back it seems good for the most part.
Only issue I had was Bluetooth in my car would cut out at a high rate of speed (when I was on the highway). It worked really well while I was on local roads but once I hit the highway I couldn't hear the other side at all pretty much. I had to put them on speaker to hear them. They could hear me really well, better than before when I was driving on local roads.
Never occurred in the past. Could it be a radio issue? Signal seemed okay and I was able to continue the conversation over the phone speaker on the highway.

I noticed I have serious data issues when the network goes into HSPA+ mode. I get really good data for a minute then it'll cut out totally for like an hour. I tried rebooting, tried battery pulling. It seems the T-Mobile radio doesn't interface well with Wind's HSPA+ . I had full bars but the internet wouldn't load. It was pretty non-functional for most of the day.
It works decently when it's not on HSPA+
Tried switching to a Wind modem, went into boot loops. Went back to T-Mobile radio. Should I try a different T-Mobile radio?

how to fix your T889v if you accidentally overwrite the radio
If you get stuck with no IMEI, in my case, flashed omnirom 4.4.1 t0ltetmo, which uses Tmobile radio... it killed the Wind Mobile radio... restoring form nandroid did not help.
solution:
flash omnirom t0lte (not t0ltetmo) and your problems are gone!

[q] lost my 3g

I can't seem to fix my signal after flashing a ROM anymore. only get 1x which is only better than no signal at all. At one time in the earlier releases of M.O.A.R I was getting LTE and 3G with no problems then later releases I've lost both. I unrooted and went back to stock and my 3G was back and rooted again, went back to MOAR and still no 3G. So now I'm on beenstalk and still cant get a signal. I love both of these ROMS hands down and would like to fix this issue without experimenting with every ROM in the forum. Has anyone else had this issue? I've resetted radios flashed different modems (except MK3) and I still end up with bad network. I need help

Open the dialpad, and then ##72786# . The Device will reboot a few times. Just let it do it's thing. It will go through the Handsfree Activation Process. This will reset your Data.
