Any idea why no rom will work? (CDMA)

I recently recieved my One V and finally decided on rooting/installing a custom rom. I came from an Optimus V and had no problems installing a custom rom in that.
However it seems that no matter what kernel/rom I use they eventually lock up within the first 5 minutes of booting and restart. I've tried practically everything and can't get them to work. I wanted to ideally run the CDMA Pacman Rom w/ the Supersick kernel. Any help would be greatly appreciated so I have can have this working before work tomorrow.

Did you do a full wipe ???

"It ain't workin" isn't enough information for anyone to troubleshoot from.
Be more specific on what you did, which instructions you followed, what ROM and what kernel, what sort of computer you're running, where you're downloading from, and the steps you are taking. If none of the ROMs are working, the problem is probably not the ROM, if you know what I mean...

Full wipe as in? (sorry, still a bit new). I did do a factory reset in CWM before installing whichever ROM I was trying at the time. I wiped all caches too.

I used the HTC One V AIO Toolkit to unlock the bootloader, get root, install CWM 6.0, create a backup and then install a kernel (I used the Super Sick JB one). From there I used CWM to gain access to my SD card and transferred over the CDMA Pacman ROM (after wiping everything clean) and then installed the ROM. It booted up successfully however as stated in a minute or so it would freeze up and restart itself. Even if I don't do anything after a reboot it'll still reboot itself anyways.
I did a bit of research and I'm thinking it could be due to the OTA Radio update from 2-3 weeks ago? I'm at my bootloader now and it says I have radio version 1.00.00.0928.
Any further help to resolve this issue would be greatly appreciated. It's worth noting that I've tried many different Kernels (repeating all the steps above with full wipes every time) and different ROMs that were supported by the kernels. I've even tried to restore my phone back to stock and it just starts skipping at the VM Boot screen.
Oh, and I'm running Windows 7.

You mean the Rom booted normally right ?? If yes then the problem is with the Rom

Pardon my ignorance but that just doesn't make sense. I've tried several different ROMs with the correct kernel's (Pacman, CM9/10, AOKP JB) and it's all the same scenario. They all boot (or occasionally don't boot and restart themselves at the boot animation) and then reboot themselves once they're pass the lock screen.
Like I said even currently if I restore my stock rom file it just loops at the VM Boot animation (which doesn't play fluidly).

Figured out the issue . It was radio version 1.00.00.0928 messing up my kernel.

[Q] Flashed Rom now Sprint activation boot loop

i flashed synergy rom r14 after rooting the device initially and everything worked out fine, then kept getting the notification for the OTA for the 4.1.2 update...being that downloading OTA while rooted is a big no no (or always was before i came to the note) i decided to check synergy for updates to the rom and sure enough it was up to r47...so i downloaded and flashed and everything went smooth but after boot up it goes through the whole hand free activation and after saying the device is activated and then going through the PRL update and that checking out, it is supposed to do the soft reset and boot up and be good to go...well on second boot up it tries to activate the phone again (again saying Activation check and PRL update check) resulting in a boot loop that never stops....where did i go wrong...every phone ive had (touch pro 2, evo, evo 3d, nexus s) has always been a pretty straight forward root/flash process...so far this one seems to be a pain....any help?

Well clearly the problem wasn't worth the rooting process because you were able to flash Synergy w/o a problem. Hopefully you have a nandroid of stock rooted. I would pull the battery and try to restore your backup. Don't forget that for this phone Recovery access is via 3 buttons: power, home and volume (I forgot if it's up or down)

its up (down goes into odin) and sadly my stupidity and eagerness led me to not have a nandroid (yes feel free to leave the backlash, i deserve it), my question is...could it possibly be i a need to flash a different kernel? another idea i had was possibly calling sprint and seeing if the could walk me through the activation process (ive had them activate rooted phones before) i cant ever find the right button sequence (ie ##xxxxxx to get into the different menus) on the web

##72786# is the code you can use in a stock based rom with stock dialer that configures the data. It establishes a connection and then runs through that whole cycle you described in the OP. I'm kinda intoxicated so IDK if I answered your question or not

So right now you are unable to get a data connection on any rom you try? If that is the case you will probably want to look in the DEVELOPMENT section for a totally stock rom that you can ODIN.

[Q] Reboots once at start up

The last few weeks I've noticed something odd which as far as I can tell is harmless but would like to understand. When I restart my Note 2 it goes through the entire start up process to the point of being on the lockscreen (perhaps a little further as I can get to home screen). It then spontaneously reboots itself! After that reboot everything appears to be running fine. Any explanation as to why this might happen and how to correct. My device is rooted. Use philz kernal 4.87. I also tried going down to 4.65 but no change.
Thanks!

Hi. The kernel is from this thread.
http://forum.xda-developers.com/showthread.php?t=2028103
It has many nice features. I'm struggling to recall when this all started. It was before I upgraded to 4.12 via kies. I actually have not done a lot of mods as I reserve my tinkering for my Note 1 and use the Note 2 for my daily drive. But on the Note 2 I first used chainfire scheme to root. Shortly after that I used the Xposed framework to have unlimited apps in multiview. Then a bit later flashed the Philz kernal (Used mobile odin to do that the first time).The other thing I use that depends on root is linux on android and titanium backup. I look at this as rather modest mods.
I'm considering starting again from scratch but if you have some suggestions I might give it a go. I'm still learning about android (here is another opportunity!) coming from a N900. It seems there is a possibility it is a bit sensitive as it is booting up such that if an app is attempting something before the boot up is completed it triggers it to reboot. (Sorry if that is vague sounding). Is there a system log I can check to possibly track this down? Let me know if you need any specific information and I'll try to provide it. Thanks!

Thanks again. You're right. That work by Philz is recovery not kernal. I've gotten into a bad habit of calling it a kernel. I think the title in the thread used say kernal but I see it has changed. I've since removed 4 or 5 apps and since then I haven't seen the extra reboot take place. So far I've rebooted 7 times today. Doesn't mean the problem is solved but it is certainly happening less frequently! If I spot it happening again I will give mrRobinson's rom a go.

[Q] Wifi/4g problems

I rooted my SGH-I317 awhile ago using galaxynote2root method. I have CWM recovery v6.0.1.4. I have flashed multiple roms including JellyThunder, Diaphanes and now I'm running Clean Rom.
I dont believe it's rom related because its happened on multiple roms but my problem started on Diaphanes and has continued on Clean Rom. When I am connected to wifi I am almost always not in service and I cannot send or receive messages. I know that I am in an area where I usually get excellent service so I'm not sure what is causing this problem.
I am still learning but I've come a long way thanks to some of you guys and any help would be awesome!

Have you done a full device wipe and restore to stock at any point to test ?
The symptoms you describe sound like something is missing. ..
It's too early to assume a hardware issue. ..
And a stock rom restore that includes the files known to function properly would be a good idea.
I suggest a full wipe, and an Odin restore of a rooted stock build. ...then report the findings. ..g

Could you point me in the right direction for such tasks?
All I found was Imnuts guide for such a thing but that is for SGH-I605 I believe.

So maybe my brain was malfunctioning...
Are you saying that I just need to flash a stock rom as I found here...http://forum.xda-developers.com/showthread.php?t=1986556
I thought you meant back to an unrooted version but then I reread it.
I always do a full wipe when I flash roms, so I'd just do that like normal?

What Modem you running? You might not have to flash back to stock.
Try flashing a different modem like the MC3, thats the latest one

I've never messed with my modem so I'd assume its as its always been. Can you link me to it? Is it the same as flashing a rom? Does it matter what rom im on?
Edit: I believe I found the download for mc3. So I just dl, reboot to recovery and flash it?

Yes, just reboot to recovery and flash it. There have been some significant improvements for some people after they upgraded to the newest modem. My data speeds over LTE almost doubled after the update.
Hope you get it working.

Very sorry for the late response ...
The thread link you posted is very old ....as we have much newer versions of rooted stock roms.
The latest is UCAMC3....and is available in the development section in several different configurations.
In an attempt to simplify the return to stock, look at the web site in the link you posted. "Scottsroms.com" is found in the developers signature line.
The site contains a rooted, deodexed stock rom that is flashable from recovery, and will produce the desired results while side stepping the need to use Odin.
Simply download the rom to your SD card, then boot to your recovery.
Wipe data/factory reset the device, and flash the new build.
Your original radio image will remain untouched, and once booted, the device will be clean and ready to be set the way you wish.
Ultimately, a simple fresh start is the logical next step....g

You are likely missing the correct APN settings. ..
Not all roms contain the pre-loaded configuration. ..
Check them in your network settings and enter then save the correct entries. ..
The APN lists can be found in the development section. ...g

New Modem...
Alright guys I tried to take the easy way out and simply flashed the CM3 modem. It has failed me. I've been on it for a few days now and run in to the same problems and maybe even worse.
I just flashed the CA4 modem to try that out (mainly because I have to go to work and dont have time to try a permanent fix right now), so I'll see how it goes. Other than that I believe I will be hitting up scottsrom.com and doing what you mentioned to side step a few of the steps for returning to stock.
I do have 1 question.....I'm on Clean Rom 4.8 and I am aware that there is an updated 4.9. Does it come with a modem? Even if not is it possible that updating would help my problem?
I appreciate the help.

4.9 does not contain a modem...
None of the roms do...with the exception of stock Odin builds...
Seriously. ..I would consider an Odin restore to stock...
You'll get all of the needed files. ..and the issues may resolve. ...g

Samsung Galaxy S4 Problem

Hello everyone,
I really need your help with my wife's Metro PCS Samsung GS4 M919N.
The thing is, we are now living outside the US so I had to unlock her phone. After ordering the unlock codes, I decided to root the phone and use a custom ROM while waiting for the codes.
That is why I found this guide here: androidforums.com/metropcs-galaxy-s4-all-things-root/790899-metropcs-galaxy-s4-all-things-root-guide.html
So while reading the guide, I aimed to have the following accomplished at the end:
Recovery: TWRP
Custom ROM: CyanogenMod 10.2.1
I then started doing the guide for the TWRP recovery by using Odin. I got the message saying that the flashing passed and went ahead to restart to recovery to install CM 10.2.1 as a custom ROM. The thing is that I keep on restarting to the stock recovery not TWRP. So I went to YouTube and found a video showing how to flash TWRP using GooManager. After following that guide, I went to restart to recovery and I successfully got into TWRP.
Now, to achieve my goal, all that's left to do is to flash CyanogenMod 10.2.1 (jfltetmo).
Before doing that, I decided to make a backup. After using TWRP to do a backup, I proceeded to installing the custom ROM + gapps (wiped with the default settings). Everything was working I think (I handed the phone to my wife so she was he one testing it). After some time, she decided she wants the stock ROM instead so I decided to download the androidforums.com/metropcs-galaxy-s4-all-things-root/783769-rom-recovery-flash-able-stock-m919nuvuamf2-rooted-deodexed-rom.html ROM.
I flashed the newly downloaded ROM + gapps (same file). This time, I couldn't get the gapps to work probably because it was meant for another version. So I decided to just restore from the backup I created earlier.
So, the usual stuff. Wipe. Restore. Restart.
Seems to be going smoothly because my wife was happy to see the old ROM she was used to.
Until the phone started to restart on it's own. (It's pretty much downhill from here on out).
At first I thought it was just a random thing that probably would never happen again. I was wrong as it became more frequent as days went by.
Recently I can't just restart the phone, I would have to remove the battery and then restart it. Now, it's getting really hard to restart the phone. Please help me fix this. I prefer to leave the phone rooted, but if the fix unroots the phone then so be it, anyway my wife prefers the stock ROM so only the unlocking was necessary.

Recovery:
TWRP 2.6.3.1

VERY GOOD THREAD!
this is how threads should be done. Very descriptive, organized, told us everything you did and asked for help! Good job man! Only negative is it prolly should have gone in Q&A section but irregardless very good thread!
About your issue, I recommend flashing stock Odin tar file to everything back to stock and reroot and start over. Flashing stock will not lock it again it will remain unlocked. But should get you back up and fresh. Just be aware it will erase all your data and all of the internal SD card.

I agree with Elesbb. If the goal is jus tto get back to stock, just do an odin flash of the stock ROM. Be advised if you flash the latest Kit Kay update you will nto be able to go back to Jelly Bean. From your post it seems like you are partial to Jelly Bean. So if that's what you want, but sure you use the stock 4.3 ROM. You can find it around here on XDA somewhere with a quick search to make sure you have the right one.
As Elesbb said, you won't loose the 'sim unlock'. But you will lose root. However you can root the stock ROM just fine.
You might also consider one of the myriad of TouchWiz based custom ROMs. They are look just like TouchWiz that your wife wants, but have a lot of optimizations and options in them. Those should flash just like any ROM. If you still get the reboot issue then do the Odin back to stock, reroot, then flash the custom TW roms.

Thread cleaned.
Rather than bashing a ROM or user let's keep on topic and help the OP resolved the problems he's having. Arguing over the virtues of a ROM doesn't help anyone.
Thank you,
Rwilco12

Before posting this thread I sent the aforementioned guide's poster (arocker). He sent me a reply saying not to use gapps as the stock ROM for Metro PCS already comes with Google apps. I'll try his suggestion first and see if the phone still reboots a lot.
If the problem persists, I will try the solutions mentioned here. Thanks a lot!

After trying arocker's suggestion to not flash gapps, the phone still reboots. So now, I am going to try your solution guys.
But before I do, I want to make sure that I am on the correct paths/links.
Here's what I found for the following:
ODIN
forum.xda-developers.com/galaxy-s3/themes-apps/27-08-2013-odin-3-09-odin-1-85-versions-t2189539
I've had a couple of chances to use ODIN but only using specific functions like flashing a recovery file while the phone is in download mode. I don't however have any experience using ODIN to put the phone back to stock where the phone gets unrooted. Having the phone unrooted is fine by me as I only needed to have the phone unlocked.
Any step-by-step guides for using ODIN for this specific purpose guys? I don't want to mess this up again.
Thanks and sorry for the trouble.

Hello PanchoPlanet,
Thanks for the link. I went ahead and tried to unroot without Windows (Mobile Odin) as per the instructions on the link. I downloaded everything and went ahead to install the Mobile Odin APK. When I ran it to install the Flash Kernel, the app told me that the device is not supported.
To my understanding the guide is for M919 devices but should work for my wife's device as well (M919N - Metro PCS). I would like to try the guide for using Windows but I'm not really expecting for it to work or I might mess it up more. I'll try to search some more and provide the links where this forum will lead me to. But if you have any ideas, please let me know asap. Thanks!

It seems like the perfect thread for what I am trying to achieve. Will let you guys know if it is successful. But it will have to wait for tomorrow. Gonna catch some sleep.

Okay, I'm running out of options. I was able to flash the stock ROM using Odin 3.07. The recovery looks like it came back to the stock recovery as I no longer have TWRP installed. When I install Root Checker, I see that I am no longer rooted. That's good.
But my original problem is still here. The phone reboots a lot. The phone is so unstable that it is barely usable.
I am now going to try one more thing.
I have a Galaxy S4 (I337M) from Rogers Canada (my wife has Metro PCS M919N). Mine got rooted and has CyanogenMod 10.2.1 as a custom ROM. My phone is working perfectly while hers reboots a lot. I was thinking it was because of a faulty battery. So I am doing an experiment by swapping the batteries. So far no reboots have occurred, but I will continue to monitor this.
Any ideas why the battery is kinda messed up?

This thread talks about battery stuff and reboots:

Batteries can go bad a lot of ways. Extreme temperature, factory defect, phone drops, moisture, etc.

And 100% of the time, they eventually just get old.

That's a wierd situation, by swapping batteries you basically performed a battery pull, which acts as a reset, that in it self may have cleared your issue.
Now if battery is bad that could be an unusual problem. Maybe just replacing the battery will be the end of your mystery.

The battery should be brand new as the phone was just recently purchased this April.
Anyways, so far no reboots have happened and any instability has not been shown at all. Everything looks ok, yet.
Anyone know if it is safe to swap batteries? Our phones have different S4 models. I'm not sure what the implications would be. Also what is this battery pull which acts as a reset? We've been pulling the battery a lot of times but the reboot still happens but not when we swapped batteries.

The batteries are all the same. Don't worry about that.
Even if its a new battery if could have just been bad. A manufacturing defect perhaps.

This battery thing is wacky, anyway swapping batteries should not be a problem, it's just an energy storage container. Pulling the battery isn't like powering down the phone or resetting/rebooting ,sometimes devs request a battery pull to get the proper wipe effect that reboots can't provide.
You inadvertently solved your problem by accident. That's a good thing.

I have quite literally solved the vast majority of my problems this way.
Its a preferred method.

Sometimes it's that "total disconnect "of power that kind of gets all the ducks lined up in a row and everything flows in the dynaflow.
Good.

its very important topics and it might seen for every galaxy s4 users.just wonderful topics.

This exact same thing happened on my mother's 6-month old S3. If you're still wondering, you could try putting the old battery and running a CPU stress test app. It should increase the current draw and trigger a shutdown.
EDIT: whoops, sorry to kind of zombie. Didn't check the date.
