Galaxy Exhibit 2 4G HELP!! - General Questions and Answers

So I got an exhibit 4g the other week, and yesterday all of a sudden in went into ramdump mode...took my battery out for 30 seconds like the idiots at tmobile said to do and now when I go to turn it on, it gets stuck at the screen that said: samsung exhibit 4g tmobile, and then turns off....i did some research and tried doing an odin flash of the stock firmware (I am familiar with Odin from the galaxy s 4g) but still the same thing happens. What's even more strange is when I try and throw the phone into recovery mode, it just shuts off as well!! Any help on where to go from here would be GREATLY APPRECIATED! Thanks!

[Q] Odin fail at CDMA modem

Hey guys, earlier today i lost service in my house, which has never happened. I flashed the new EP1Q modems a couple days ago and they have been working well until now. Figured something must have happened with the modem so i went to reflash it, but the flash failed during the CDMA modem part. Tried flashing EE4 modems, same thing happened. Followed imnuts guided to fixing phone, but both roms included got stuck at same spot while flashing. Anyone know how to fix this?

did they actually fail? I know the CDMA modems take quite a while to flash in which it looks like Odin is 'stuck'

might have been a bad file, maybe download again and try over? what Odin version 1.3, 1.7, or 1.8x?

Flashing with the battery in or out? When you're flashing, does the text on the screen of the phone change when it gets to cp_modem.bin?
using odin v1.82. I'll redownload the modems and give it another shot.

Flashing with the battery in. But since this happened i can no longer get my phone into download mode without putting the battery in first. I have a progress bar on the phone until that step, then the progress bar goes away, and all that's left on the screen is the "VIA" message that's always there. I forget what it says though.
To be more specific, here is the process i took today to try to fix the problem (Repeat of last night). Tried to flash EP1Q modems through odin: Failed during cp_modem. Tried to flash EE4 modems: failed during cp_modem. Redownloaded EE4 modems: same failure. FLashed the pit file and re-partitioned phone: successful. Flashed the ED1 package in OP: I get a progress bar until completion of lte modem, then progress bar goes away, screen says VIA reset done. Odin acts like it's fllashing the modems, then fails after about 1 minute. Tried different full odins, same result. Hope being more specific helps things. Should mention my phone does boot into what appears to be stock ED1, but now there is a SIM card error as well as the no service problem.

damn, worst case scenario you may have fried your radio or 4G sim if its not flashing anything properly and you get no service... if its really stock (so they don't suspect foul play) i'd take it into VZ and see what they have to say

Well, took my phone into VZW to have them take a look at it. Luckily, the sales rep. i got knew less about the phone than my little sister. Turns out i was getting a sim card error because i put it in upside down *DERP*. However, it did give me an excuse as to why i wasn't getting any service. Rep. started messing with settings and screwed things up worse. Long story short, new phone will be here monday. =) Thanks for the help. Think i'm going to wait a while before i root this one, seems like my kind of luck to have something like this happen to me.
*Edit: Did some more research, looks like you were right anoninja. The CDMA radio is fried. But lte seems to be working. Too bad the nearest lte area is 3 hours away. haha.
Same thing happened to me on my first Charge. The bad part is that it didn't happen with Odin...it was the OTA stock EE4 update that did it. It installed, then after the reboot, I didn't have voice or 3G service, but I was getting LTE, and the About Phone screen reported "Unknown" radio version for CDMA radio. Verizon replaced without any resistance, but the phone was basically brand new at the time. Not sure how they'd be now, two months later.

Verizons got tons of issues with 3G/4G combo phones and the signal handoff between the radio and 4G sim. This is most likely due to these phones being the 'first gen' of 4G, we are kind of almost unpaid beta testers for it. As much as it sucks tbh I'm not surprised to see how many people have had to get new sim cards or replacements due to bad radios

I have a rooted Galaxy S3 with the Hyperdrive ROM. It was working fine for a few hours until it froze and randomly rebooted with the Verizon LTE load up screen.

[Q] Metropcs Galaxy Mega

Hello guys I have the Samsung Galaxy Mega from Metro flashed with CM11 and it very unstable. I have the cm-11-20140519-UNOFFICIAL-meliusltexx and my phone seems to not get calls and when I dial it takes around 20secs to get a tone. Also I get really low signal. I live in Vegas and normally 4g is good around here. Is this normal for the phone or is it just Metro? Also the phone doesn't even say Metropcs anymore it says T-Mobile. Thank you for any help or suggestions ~J Paez
