Hello All,
I'm not to this forum. I'm having a very strange issue. I had unlocked and flashed a scotts clean rom to my phone. This rom worked fine. It was the cleanrom standard 4.4. Everything worked fine, but I wanted to try something without sense. So I followed the instructions and ran scott's wipe program that wipes 5 times over. Then I did a wipe on the device. From there it got stuck in a loop where I would boot it into the hboot and it would try to load that weird PH89IMG file and then reboot and do the same thing.
Believe it or not I resolved this by removing the SD card then booting to recovery then slightly lifting the battery and inserting the sd card in and mounting so that I could load another rom after mounting it. Just to be safe I did perform one more wipe. I loaded the CLEANrom tapped edition. It installed and booted up just fine, only one problem. I cannot turn the wifi on.
So I cleared the cache and Dalvik cache, rebooted. still no wifi. It sits on turning on. The wifi mac address is obviously unavailable. It went to an error evetnaully, but there was no detail in it other than the word ERROR. I tried reloading the ICS kernel as well, still nothing. I didn't see anything in the forum on this issue, so I am not sure why it's isolated to my device. can you help me?
Thanks.
I know your tired of wiping and flashing but this has happened to me before on a previous Clean Rom version. Wipe then reinstall ROM. **Caution** Before you boot to Rom, boot to recovery and flash the kernel that came with the Rom. That cleared up my broken wifi. Also beware that if the Clean Rom tapped edition uses a different base ie. 3.14.605.05 or 3.14.605.10. then you have to flash the Stock Rooted RUU of 3.14.605.05 or 3.14.605.10 and then wipe and install ROM. link to stock RUU:

I have had this issue with a couple newer ICS ROMS I have tried and it all seems to come down to reflashing the Kernel. Even after updating Nils' Roms to newer versions my rezound would load up fine and everything worked except wifi. If I went back into recovery and reflash the kernel wifi would be back to normal again. Make sure you have the correct kernel designated for that ROM as I have noticed some Kernels need to be redownloaded and reinstalled seperately. Good Luck
Hello,
I am having the same problem and I am on Rezound Pure GSM sense 3.6 rom.....I am confused whether to flash the wifi modules for the new kernel from the above link....I don't wanna take any risks as I finally got my GSM working on atnt.
Thanks!!
I know there's a few posts on this, but looking for advice specific to my symptoms. The problem started off with Android media process using up a lot of cpu each time the phone was powered on. It gradually got worse and started rebooting when this happened. Started off as once or twice a day. Then got worse and worse. I had been on a bell atrix ROM (2.3.6) for about a year.
Tried flashing a number of roms, and making sure to clear caches and factory reset each time. Tried numerous versions of the CWMRecovery, no good. I notice that it noly seems to restart if it tries to communicate wirelessly (wifi or 3g seemingly). If I just leave it in cwmrecovery, it stays on fine. If I leave it at the first motoblur setup screen, without entering wifi settings, it stays on fine.
So I guessed it may be related to the radio. Installed a UK radio, bell original one and a euro one to no avail
Is there anything else I can do before I give up, or is it hardware?

just had a look around and came across this http://forum.xda-developers.com/showthread.php?t=1884381 . Forgetting the Jb reference it might be an idea to follow the steps and see if that helps.
If it were me, I would do a complete system wipe first (CWM>mounts and storage>format system,data,preinstall,osh) and then reinstall a rom (I would recomend CM7.2 to start). I also might be inclined to take the external sd card out as well before restarting phone and see if that helps (going down the corrupt media file route)
Good Luck!

Thanks for this, I never spotted the mounts and storage section for formatting before. Looks to be good to get a clean wipe
Will try now
I managed to get the MROM rom on to it, and it has stayed on for about 30mins now with wifi on.
However, it doesn't boot normally, it says 'Modem did not power up, starting RSD protocol support'. I have to choose Boot Android (no BP) to get it to boot ok. What would make it fail like this?
Is there any way to make the phone always boot android by default?
Another thing to add: I can't add any APN. If I add one and save, it doesn't save.

I can see that i am missing a boot.img to make it boot properly. Where can I download it?
A boot image always comes with any ROM, and MROM is no exception. If you sucessfully flashed the ROM, you've flashed the boot image too, I'm not sure why you think it's missing. But if you really want to reflash it, you can always extract it from the ROM's zip file.

Alright, looks like I misunderstood the function of the boot.img. Any idea as to why it would not load the OS without me prompting it to boot android with no bp?
What is the best process to follow before flashing a rom?
I was doing factory reset,clearcache and clear dalvik from CWM. And I have started doing CWM>mounts and storage>format system,data,preinstall,osh now too.
Is that sufficient to get a good clean slate to start fresh?
And what's the best way to flash the radio? I have tried moto-fastboot radio radio.img, but that seems to stop the OS from loading. I assume the radio be installed after the ROM?
Tried an older gingerbread Bell rom, and same problem. I can only get it to boot by choosing boot android(no bp).
I also can't add an APN to it. I create it, save it and it doesn't save it to the list.
Found a fix here for the APN problem on ICS, but wondering if there's an equivalent on Gingerbread?
'Settings --> More... -> Uncheck 'Enable alt OEM telephony code' and 'Enable alternate getIMSI code'. Then reboot, and now you can add your own apn. '
No idea really, sorry. Kinda seems to me for some reason it's your bootloader that's having issues, not the ROM.
Still cant get it working, can't add an APN.
Replaced the SIM, same.
Noticed that the IMEI and baseband are listed as unknown, and think it's related. So I tried flashing a few radios.
Bell radio stays on about a min, then reboots phone
UK radio reboots once OS has loaded
French radio reboots once OS has loaded
I am based in Ireland, using a phone that was originally Bell Canada. Which radio should I try flashing?
Have you tried AT&T 36p or 37p radio?
No dice. What is the standard process with the radio zip? I have been extracting to a folder, then using moto-fastboot to clear the cache, then install the radio.
Am I missing a step or 2?
Why were you extracting it? Most radios come in a flashable ZIP, which means you flash it through recovery. No extracting.
I always got an error trying to install the zip in CWM. So installed img from fastboot instead. I'll try the newer zips from CWM.

I get error 'assert failed' ...status 7.installation aborted..'trying to install both ATT radio zips via CWM, and status 0 trying Bell radio zip
Update on this:
I got a new phone a few days ago, and had trouble adding an APN (same problem it wouldn't save). Problem was it was not reading the sim correctly. I had some sellotape on part of the card. Removed this, and I was able to add the APN no problem.
I have cleaned the contacts on the sim card reader, no luck.
I am convinced that this is the faulty part though. When I go to add an APN, it should automatically populate the MCC and MNC from the sim, but it doesn't.
Sorry to bump an old thread but...
I have left this Atrix aside for a few months,and wanted to try it once more before giving up entirely.
It reboots when I use 3g or wifi. If I leave it offline or in cwm mode, it stays on ok.
Any ideas? Is it definitely hardware? (Have tried about 4 different images)

Does it reboot if you put it in Airplane mode, then connect to WIFI only?
My Atrix randomly reboots if I have the cellular radio on, but if I put it in Airplane and only use WIFI, its very stable. I tried dozens of radios and ROMs, nothing seems to help, so I've chalked it up to some flaky hardware.
*READ BELOW FOR A GUIDE TO FIX*
I've had my note for over a year now and i have had it rooted pretty much the entire time. Never any problems with it up until recently it started doing this thing where it would keep restarting. It would boot up and less than a minute later just restart. Off and on for a few days it was doing this. I was still running 2.3.6 at that point. So i decided to push 4.0.4 via odin since kies didnt support the firmware. Everything was working fine for a few hours then all of the sudden "the ring of death" showing me no service. Went through the phone and noticed it was saying there is no sim inserted. Tested sim on another phone. Works fine. Since then ive figured out via kies i can recovery and update firmware. Tried that. No Bueno. Now im to the point where im on 4.0.4 with no service. I've scoured through forums trying all kinds of different things, pushing different roms and modems via odin and cwm. Still no bueno.
Baseband version
Unknown
Kernel Version
3.0.8
Build Number
IMM76D.UCLF6
If anyone can give me ideas im willing to try them out.
Thanks.
I got it working so heres a direction for anyone else who has this issue!
Replaced Sim&SD card reader-No fix
After flashing all kinds of roms & modems still same issue saying no sim inserted.
Do a hard reset through your settings.
Flash cwm and put the radio from this link on your sd card. Use cwm to flash the radio.
Flash rom http://forum.xda-developers.com/showthread.php?t=2261598 via odin.
The first try i got an error during flash and got stuck on the software download error screen.
Reflashed the JB rom.
After its flashed flash clockwork recovery.
Enter cwm and do a factory reset. Clear cache. Clear dalvik cache. Reboot system.
If you get service, turn off phone. enter cwm and do a backup.
Reboot system.
It should be working.
If not restart and make sure to do a factory reset through your settings in the phone before reflashing rom.
Got the Phone up and running for about 30 mins.
After battery removed it reverted back to no sim card inserted.
Kept reflashing rom until it worked again.
Flashed cwm.(ClockworK recovery mod)
Deleted cache, dalvik cache
Backed up via cwm
If it reverts back to no sim after that restore using the cwm backup.-it worked for me
Now for the tricky part, my phone was getting crappy service...
So heres what i did to fix it.
Settings-more settings-mobile networks-access point names-click on the apn.

Hope this helps anyone else having this issue.
I believe I've read something like this before. I think they fixed it by starting over from scratch. Try returning to stock thru Odin. Then root and flash rom of choice.

GB stands for Gingerbread which was the first version of the OS that came with the phone. I believe the number was 2.3.6 (you can take a look in the about section in the settings and it'll tell you what you're currently running). ICS is Ice Cream Sandwhich which for our phone was 4.0.4 i believe. Jelly bean just came out today which you can use Kies to upgrade to and that I believe is 4.1.2. The numbers don't really mean a think, just the classification of what the OS is so if your phone reads something else (say 2.3.4) assume your phone is right and I'm wrong. I can't remember OS versions to save my life haha.
But you can use Kies to do an emergency recovery and I THINK it'll install Gingerbread. that's where I'd start, then test it, and then move to ICS and test, and then move to JB and test. I know long tedious process, but sometimes it's necessary. Imagine how fun I am to talk to on the phone while troubleshooting a computer :laugh:

what I use to migrate, and I between roms at least once a week with a full wipe because I rely on my phone being stable.
SMS and call logs: SMS Backup + (saves your call logs and sms to your gmail account. Makes a label for it and everything, pretty sweet. You can also restore from it. it takes about an hour for me to restore at 7000+ text messages).
pictures/media: stored on SD card
apps: if rooted and rommed I use titanium backup and run 2 sets. those which I want to keep my data like sms backup + to make restore easier and those I don't care about the data like google voice. If you're stock, just remember to check the little box in the beginning saying backup this phone to google (or something like that) and the next time you have to restore tick the box that says restore from google (or something like that) and it'll reinstall your apps. Mind you not the info, but it'll give you a head start.
As with your issue with installing roms. If you're using CWM i highly recommend switching to TWRP, not saying it's better in fact I like CWM better, but TWRP is the best for our roms and phone. If you have no clue what I mean by CWM or TWRP, read the all info sticky about how to rom thy phone.
I hope that helps.
Thanks OG. Yes, I know CMW and TWRP. I used to switch ROMs a lot. Finally stuck with Collective's latest (the orange one) pretty happy with it except that it's major glitch seems to be reboots whenever an app updates. So I figured unchecking auto update in Gstore should handle that.
You're saying I should try rooting w Odin again, install Superuser, then use TWRP to flash with? I'll be happy to read another 4 hrs of posts/stickies if that'll get me sorted out. I don't expect people like yourself to spend your day helping me. I'm very thankful for your tips here.
I've poured thru the "All things Gnote" threads and Noob Guides. They can be confusing as they always link out to many different threads. There is hardly ever a "Here are the steps 1. 2. 3. 4. 5.
Thanks again OG.

No problem always happy to help. since you're used to this sorta thing you don't need to use odin again and reroot. What you can do is either install TWRP through CWM using this file here:
http://goo.im/devs/OpenRecovery/sgh-i717/openrecovery-twrp-2.5.0.0-quincyatt.zip
Or you can install Goo manager, click settings and select Install OpenRecoveryScript (though that's only 2.4.4.0 the link above is 2.5.0.0)
That should change you over to TWRP. and like always do a nandroid backup and then flash to your heart's content!

i have the same issue.....i kn0w its n0t an hardware issue....my ph0ne is fairly new never dr0pped and this started happening 3 days after i p0rted black star jb alpha
I have this same issues ive tried flashing everything ive tried a new sim and replaced the card reader.
What works consistently for me if to flash the latest modem everytime i have to reboot or boot the note. Its my daughters phone now and she drains the battery regularly if it boots after charging or it needs to be rebooted for whatever reason it will come up with the no sim card error. If i flash the modem thru recovery it will work for that boot but only as long as I dont reboot or shut the phone off, then i will have to flash the modem again.
Not fixed
All. This is not fixed. I am having the same issue and if you follow the guide, it works for a day maybe regardless of what rom is loaded or what modems. Has anyone found a real solution to this yet??
i717 running stock GB or ICS or JB roms...
Thanks!

I'm having the same problem. There seems to be no set way to get it back to working. Basically any reboot of the phone produces a no sim card error. I have tried flashing the modem through recovery as it was mentioned that will fix the problem. That did not work for me. What does work, sometimes, is one of the following:
1. Full wipe and reinstall
2. Restore backup from Recovery
3. Fix permissions
I just keep doing one of the above listed and eventually it works. However if the phone reboots then it's back to the carousel of trying these options to get it back to working.
I'm running Padawan JB V2
I honestly have no idea what's causing it. I haven't tried to fix permissions before to fix this issue, but if I go into recovery and install the modem again and reboot, it works fine for a while (and by a while, I mean like a few hours at max).
Just started having this issue, myself...after flashing Tmo_SGH-T989_VKL1_radio_ATTNOTE.zip modem on my phone...restoring from a prior backup...
Restoring a backup will not change your modem.
I'm using the up-to-date version of TWRP 2.5.0.2. I followed the instructions to flash Hyperdrive exactly (3x wipes, wipes, install, rebooting, etc). My phone works after the first reboot, but after I reboot the second time after 10 minutes my phone consistently bootloops every time after that. Does anyone have any idea what's going on?
I'm running the RLS3 right now because I was tired of being afraid to reboot my phone lol. It's pretty stable, the only problem is that I find I can't make a nandroid backup- the data partition is ludicrously large at 2 TB, and I can't figure out why.
Anyone have any ideas? Thank you!

You can try and switch the kernel and see if the problem still there. I would go with KT Kernel http://forum.xda-developers.com/showthread.php?t=2294083

Hello all.
New poster here, been coming here for some time though for the loads of great information and generally helpful people.
I'm having an issue with my Honor 5x, and I seem to be the only one i can find on this forum having this issue.
The issue that I am having is that I lose the ability to connect to the cellular networks (I am actually running dual-sim) when I load a custom ROM after the first reboot.. The first time this happened, it even lost the IMEI numbers (WTF). I restored from the backup I made, and tried again. I got the same result, after the first reboot, it can no longer find the cellular networks, and when i try to search for network providers, it gives me an error simply saying "Error searching for networks." Restore backup again, flash resurrection rom to see if maybe CM13 is just being stupid with my phone, got no signal right off the bat, and could not find networks.
At this point, I restored the stock recovery, and let it recover my phone to stock, which is where I am at the moment, since it works. Also noteworthy, that every time I restored from backup, the phone had no problems at all connecting to the cellular networks. as well, it never had an issue through all of this with connecting to WiFi.
Relevant Information:
Phone Model: KIW-L24
Build Number: KIW-L24C567B331
Emui Version: 4.0
Android Version: 6.01
Kernel Version: 3.10.49-g472a5b3
Location: United states
Carriers: Cricket, MetroPCS
Bootloader is unlocked
I have not restored root access
I have Flashed TWRP and made a full backup (again)
I'm getting the feeling that it is due to to something that I have forgotten, but I can't seem to think of anything.
Help?
So close, but no cigar.
Still having issues, here's what Ive done so far:
Restored phone completely to stock, leaving only an unlocked bootloader.
Loaded the latest version of TWRP
Re-Rooted the phone
Made a complete backup of the phone, with no partitions left unchecked, in case of a catastrophic failure
Used TWRP to wipe Dalvik/ART, Cache, System, & Data
Loaded the latest CM13 nightly build
Loaded GApps pico version (I don't use many of the Google apps, so I prefer to download the ones that I want)
Wiped Dalvik/ART
Rebooted Phone
At this point, the phone went about its first boot business, loading stuff in the background, optimizing apps for the first use.
I skipped almost all of the first-time setup stuff, no sense in setting it all up if it didn't work this time as well, but connected to WiFi, selected the primary SIM, and activated data on that SIM. This is all normal from my other attempts as well.
Rebooted the phone, when it came back up, I had signal on my phone, and it successfully sent and received messages.
Added my Google account, rebooted again, not getting signal. checked network operator settings, and I get the message stating "Error searching for networks" for both SIM cards.
Removed Google account, changed SElinux settings to permissive, soft reboot, no change.
In the past, I did try wiping Dalvik/ART & cache once this happened, but the only thing that changed is that it caused the process com.android.phone to crash on me repeatedly.
Currently digging around on the net some more to see if maybe there's something that I missed.
Try 1 Sim? Its some bug with dual sim i guess
I will try that when I get a chance, I am currently trying to restore the phone back to stock again after another failed attempt.
Also noteworthy, I had it completely lose the sim cards on me after a restore to the working stock backup that i made earlier in the day yesterday, I had to completely revert to stock (Restore stock recovery, let it rest the phone to stock) then the SIM cards started working again.
This is starting to get rather frustrating.
I'll keep you updated, as I've kinda decided to make this a log of sorts of my experience with this.

Im having the exact same Issue, All roms loose the SIM card so I loose all signal and basically everything... a restart sometimes helps it, tried installing different ROMS, going back to STOCk 5.0.1 or 6.0.1 nothing Helps... NO clue what to do.
Same issue here. Happens on every Rom.
EDIT: Using KIW-L21 (UK)
Unlocked, single sim.
Maybe the it has something to do with modem.img
