GPS After ICS Upgrade - Samsung Epic 4G Touch

After upgrading from gingerbread on my phone, GPS doesn't work at all. I didn't know at the time that I had to leave the GPS locked in GB before the flash to get it to work. My question is, since flashing back to the "StockCWM-EL26.tar.md5" makes the phone not boot, I can't just go back into GB, get lock, then go out. Does anyone know what I else I can flash to get a bootable phone that I can get GPS lock on?
By the way, I had family here this weekend and two of them also have E4GT, so I did an experiment. I upgraded those two phones to ICS with GPS locked ahead of time, and both worked fine. However, there's definitely a difference in these phones that were purchased at the same time. One of them got lock within 10 second when I sat inside at the kitchen table. The other one could never lock here. Both locked outside though.I repeated this experiment several times, and it was consistent.

The safe thing would be to Odin back to EL29 and start over. I'm using stock FE22 and there is no problems with anything.

Most ROMs require you to ODIN back to Stock-Rooted-EL29 -> Get the GPS lock -> ODIN to Stock-CWM-EL26 -> Hold the volume up key while booting to get into CWM -> Clear data, wipe cache & Dalvik -> Flash your ICS ROM of choice (and Google Apps, for Maps) -> Go into Maps and see if you get a lock.
Make sure you flash back to Stock-Rooted-EL29. This is essential because it restores all of the stock settings before modification.

So it isn't necessary to ODIN to el26+CWM if I ODIN el29+CWM?

Ok get back to a GB rom either by sfhub odin or odin el26 kernel and restore an old GB rom get a lock and leave gps on then restore or install an ICS rom...

Had same problem with cm9. Downloaded agps from market, cleared GPS from the tools menu, let it run until it got a bunch of locks, then uninstalled it and my GPS has been spot on ever since

Can I use the method in the link below to get a GPS lock, then revert back to my running ROM (AOKP)?

Constant FC - Can't even make a call after going from eh17 back to ec05

I updated my stock-rooted ec05 to eh17 recently just to try out gingerbread, but it kept rebooting on me, so I tried last night to go back to ec05. I had downloaded the latest odin, I already had drivers installed, I even had another ec05 zip file with cwm 3.1.0.1 built in, and I had dg27.tar as an old standby. After many, many, many, many, many attempts, I finally managed to get the right combination of pit, tar, cable and usb port to get the old dg27 installed. It seemed to work ok, but seemed a bit slow. I did an upgrade to the latest ec05 using the built-in update tools. It was a 99mb download/update and it went fine. Then I re-rooted it with cwm 3.02.5 and updated to 3.1.0.1, but the actual phone part is just crap. It boots up ok, but then just FREEZES. It doesn't matter if I have the sd card installed or not, I can barely launch programs, I couldn't even make a phone call...the PHONE app fc'd on me... wtf??? the PHONE app fc'd on me... I can't even use my smartPHONE as a PHONE!!!! And I'm getting completely fed up with how slow it is and how it fc's 98% of the time and takes 10x's longer to do anything even when it does work. Thing is, my internet connection is only 512kb/s downstream...yes, that's only 512KB/s...so I can't just go around downloading .tar files everywhere trying each one until i find one that works. Plus, I knew the official gingerbread release is just around the corner, so I wanted to be back to stock for it. But I can't get this damn thing working to save my life and it's pissing me off to no end...I've wiped the cache and davlik cache so many times, it's not even funny. I don't want to just do a factory reset, because I have 18,000 txt msgs that takes an hour to restore and I have visual voicemail that I use and have tons of those saved and that requires using root access to copy the folder where the data and audio files are stored in the root in order to back it up.... so it's a pain each time I want to start over...
Anyone have any bright ideas? please???

I can't think of anything to do but reload. I would back up my sdcard. Wipe everything 3x. Reformat the sdcard. Install Deca's Deodexed EH17 twice in a row without rebooting and see if that works for you. I have been using it with no problems. If you are set on EC05 than Odin EC05 instead. I would not go to DG27 and then up to EC05. Just go straight to EC05.
@crawrj, I'm serious man, GB is shifting the partions around some how, and not getting fixed when going back to froyo.
A lot of EH17 data is not compatible with EC05 that is why you are having so many FCs. A factory data reset is your best bet to get your stability back. Restore only data that you absolutely have to have. I had a buzzing in EG22 today from a EH17 downgrade that I couldn't find so did a reset myself today. But my phone is superfast and smooth again with no errors, so totally worth it. Restore your texts when you go to bed and will be done when you wake.

Not sure what that could be. I went from EF02 back to EC05 without any problems. I went back to Gingerbread on EG22 and have been here since.

Its random when it errors out but when it does, it can be bad to the point of having to Odin. Sometimes flashing a Froyo ROM fresh fixes it but sometimes it doesn't. I can't explain why it doesn't happen every time but I have been flashing 2 to 3 ROMs a day the past week and about 25% of the time, if I don't Odin, it can't be resolved

Yup, something was changed in that EH17. I have to redo my email accounts rather than restore the accounts and data.
I been going back and forth between GB and Froya. everytime i go up and down i use odin. if you want to make sure that your phone goes back to the manufactory settings then you need to have (Phone EFS Clear) checked. that will bring back everything to the first day you bought your phone then you can start again with whatever you want.
as far as backup up the files, first root your phone and go to 4shared.com and download (my backup pro .apk) this will allow you to backup and restore everything you have at one shot.
i hope any of that help
If you wipe everything 3x, reflash a ROM and reboot, it will usually (but not always) eliminate the problem. Then wipe everything 3x and restore a nandroid. You should be good. If it doesn't work after a clean ROM install then Odin is necessary

I ran into a similar issue, went from EH06 back to my daily driver EC05 that I had a nandroid of. wound up having to wipe everything, do the full EC05 rom install, kernel flash, and then run the restore to get it to boot. Not sure what the deal there was, but still got it working.
I recently jumped back to EC05, I just wiped 3x, flashed my ROM and then restored my APKs (never the data) brought back my call log, sms, mms, alarms and dictionary and have had no issues.
I tried, Bamboozle (EF02), Go Green (EG22), Osprey (EG22), Hawk v1 and 2 (EG22) and Vendetta (EH17)
I got tired of the rebooting in the leaks, I like being back to like 3-4 days on my ext battery with midNight 5.3
10/10 sat in GPS with 2.6m acc (using EH17 modem too)
Is Midnight EXT 4 based? I'm still on Stock EC05 RFS, but wondering if flashing the EH17 modem would be better...not all that impressed with the EC05 modem.

This +1
For me the EH17 modem has been the best I have used... but as with everything YMMV!!
I do agree that the EH17 modem is good, but the GB ROM that comes with it is broken. I got a lot of FC all over the place out of nowhere with the ROM. Since then, I've changed the ROM but kept the Modem and things are running much smoother.
GB leaks have many issues still and I think its still wrong to make them the everyday driver, in addition to that, we are not getting much benefit on having GB right now, many apps that were GB only are running perfectly fine on Froyo... My suggestion is, test the leaks if your feeling adventurous but expect issues.

running last cm9 nightly...still no gps...tried some fixes...

Am running CM9 nightly (9.16) and everything works great except I can't get GPS to lock on..just sits there with "searchign for GPS"...
What I've done so far:
- "GPS Fix" flashed from CWM....no help
- "nexusmodempatchcm9.1" flashed from CWM...no help
- "ns4g-radio-KL2" flashed from CWM...no help
- tried the temporarty boot method here http://www.youtube.com/watch?v=g2r7anSiI5I but that was for the Epic Touch and it didn't work or maybe I didn't do something right....it would just hang and couldn't get into CWM after reboot
- finally Odin'd back to stock, ran the GPS fix from the App store and got GPS to lock
- flashed my saved CM9 image from the day before, downloaded the GPS fix from the App store and still got no GPS lock
Is my image from the day before the problem? I thought the GPS fix done from stock would've carried over to the GPS in CM9...at least that's what I thought was the point of that...
Would just flashing CM9 again work? (but then I'd have to restore my apps from Titanium Backup..also from a day before saved)
*confused*
Thanks
Yes. Your image has bad GPS data. From stock with GPS on and locked flash CM9 and do not restore anything and test GPS.

thanks for the reply....a couple of more questions pls:
- when i flash back to stock, will i lose root and/or cwm? am assuming no
- if i titanium backup my apps again now, can i restore without a problem since i am backing up from within cm9 and not any cm7 rom

Yes when you Odin to stock you will not have root but you are only testing your GPS. Then leave it on with a lock, Odin cwm 5.0.2.7 with reboot unchecked, when it completes pop battery out and in, 3 finger to CWM and flash CM9 and gapps. Start phone and test GPS. If it works then yes you can restore Titanium Backup stuff but no system data.
GPS works on CM10 without GPS Fix.

This. Went from various Gingerbread updates straight to CM10 mainly for GPS stability actually. Had trouble keeping lock on GPS all the time and used phone heavily for multihour navigation; for like 2 years.... Since CM10 have had 0 issues. It was almost a religious experience.

Do You Ever Go Back To Stock?

I personally think stock is filled with a bunch of nonsense that I never used. I am absolutely in love with jellybean and I'm never turning back. For a fresh install I just use el26.
Yes I always keep a stock 1 click on my laptop to update prl and profile then get gps lock. It also cane in handy when I installed a bad zip and my nandroid was corrupted. I only had about 5 minutes before I had to leave the house to gwt the phone back up and ran stock all day that day.
I stay on stock rooted, its safest, great battery life and I still have 4g

Odd data issue after switching from rooted JB to ICS

I was having issues with my GPS not working so I Odin'd back to rooted ICS and fixed it using the dialer wipe option from one of the threads here. That Odin flash also flashed the LG1 modem back onto my phone. I then restored my AOKP 4.2 nandroid and everything was cool, but I noticed my data would never switch from 3G (UMTS:3) to H+ (HSPA:15) sometimes leaving me without a data connection because my area is weird about stuff like that.
After realizing is was back on LG1 modem I flashed the JK3 modem and my phone would connect to H+ again.
Just wondering if anyone else had this happen to them or know why it would happen. FYI, back on LG1 before the JB release my data was fine without any issues.

If you want rooted stock ICS download one of the root injected Odin images from the no trip root thread. If you don't want root, then download a stock image from the stock images thread. Pretty simple, but you will have to wipe data or you will get bootloops or force closes.

Download EL26 safe recovery
Download GB Blazer ROM
Download EL26 Modem
Download the ROM you will install + Gapps if necessary.
Download the modem you will use for the ROM of your choice.
If you are using MobileODIN his will be much easier.
1. Flash EL26 safe recovery
2. Once in recovery mode, wipe user data, wipe cache, wipe dalvik 2 times each.
3. Flash GB BLAZER ROM
4. Flash EL26 MODEM
5. Reboot and run the ROM, immediately go to maps and get a LOCK on GPS.
6. While LOCK on GPS, reboot into recovery (It should be Clockwork Mod recovery 5.0.2.7)(if not go back into the phone and flash the recovery from ROM manager app, if it was already installed [I can't remember])
7. Perform a backup.
++++
Now it's time to install your ROM.
++++
8. Wipe the 3 things above on #2(1 time only).
9. Flash your ROM of choice + Modem of choice +Gapps (last) if necessary.
10. Reboot phone and immediately check GPS.
Hopefully his was helpful.
I will tell you it's a hardware issue the way the GPS runs thru the Processors cache, or something like that. When we wipe it clears the GPS and it's hard to get a LOCK.
I read that.
Let me know if you cant get a hold on anything listed above.
