I have a 7" tab that was given to me by work, for work. I use is mostly for the 3g hotspot, but I've noticed that the internet lags pretty badly. It constantly hangs, and freezes up. I have a samsung fascinate that I'm running miui on, and when tethered to it the internet runs great. I'm wondering if this is a radio issue on the tab, or if I maybe need to flash another kernel to fix the lag that I am experiencing with the stock software. I don't want to flash any roms, as I don't really use the tab for anything other than as a 3g hotspot. Any help would be greatly appreciated.
Ok, I see that there is an EC011 modem available. Is that compatible with the stock froyo, or is the stock froyo the issue? I'm starting to think that the modem isn't the issue, and I'm going to need to flash GB or a custom froyo rom to fix the issue. Anybody else have this issue besides me?
So.....I've decided to flash the 2.3.4 leak. It's my first time using heimdall, so I want to make sure I have the method straight and have all of the items i need. I just need to unzip the file, then select the appropriate files. Then, I need to select a modem and recovery. Do I use the zImage for the kernel and the recovery, and is the EC011 modem compatible with the gb leak? Any help before I mess something up would be greatly appreciated. Thanks in advance.
the modem (which you call a radio) should have little to no impact on the rom itself.
most kernels should have the recovery built into the zImage file, so only put it in the zimage slot in heimdall. Only put something in recovery if there is an actual recovery file in the tar you have extracted.

Yeah...I was at work, and got my terms mixed up. I ended up flashing the stock gb leak with heimdall, then flashed the modem.....soft bricked it somehow, then reflashed the rom. All came up well, but the 3g hotspot was still slow and buggy. I decided to try barnacle wifi, which I use on my phone, and that solved all of my issues i was having. I'm guessing the 3g hotspot verizon app is just flawed. After installing barnacle, I ran a few speed tests. I consistently hit 2.5mbps down with almost a meg up. With the 3g hotspot app I hit 300-400k down, and 500-600k up.

I recently updated and the 3g performance seems incredible slow compared to the stock rom. Is ther a reason for this or is there a stock rom dl out there that I could go back to?
Thanks

It's because of the MODEM.. Use a different MODEM.. Try UGJL2
ok im a total noob to andriod. I can pretty much do anything with a computer.. SO is it the modem driv er on the flash that isnt playing well with the hardware? How does one update the modem settings?
Thanks

Good place to find some if the modems that are available. You want modems that are cwm updates.
Down load modem, move file to internal sd of phone
Boot into recovery
Install zip from sd
Choose zip
Select the modem file
I would suggest jk4
ok loaded jk4.... no change if not worse.... Where can i dl the original fl6 for cwm.... This really sucks.. im thinking i never should have flashed

The downloads are all zips. You flash the entire zip. Did you pull the modern from the zip?
Get into recovery by long poss on power select recovery from extended power menu
Try putting your phone in airplane mode, then restoring service
well that didnt work either. the jk6 jacked up phone calls too. heres the current incarnation on ATT
firmware 2.2
baseband i897ucjj4
kernel 2.6.32.9
cognition 3.04
Market is dog slow... if it will dl at all... I cant use the original stock modem with the 2.2 upgrade can i.
jk4 not jj4. That is not the modem I said to try
Jk4
i did use jk4. that was the one that hosed everything up. i couldnt call out but could txt. i went to jj4 just to get it working again i cant find the original modem rom anywhere
Like the others said. When you download the modem it will be a zip file. Leave it as is and copy it to your phone. Boot into recovery, choose install zip from sd, choose zip file, navigate to where you saved it it and flash.
Be careful changing modems. I9000 modems dont play well with captivate kernels. Cog is pure captivate, so if you flash jk4 modem you should probably flash another kernel, ie, Firebird or speedmod.
I can assure you that if you are in a good service area, Cog 3.04 kernel/modem combo are great. I would personally flash back to stock and start fresh.

My suggestion is to try another rom or flag back to stock
That's what i think im going to have to do. I just got a full titanium backup done. Stupid question is there any way to flash back to original config with cwm or rom manager
Yes and no. you can flash the jh7ota package that can be found in the development section.
If you were going to do so you must didable lag fix first. I am not suggesting this though.
If you are going back to stock, I would use odin. Do you know what build phone you have, located under battery, something like 1008
sn r1xzc87098a no 1008 anywhere under battery
It will be anywhere from 1006 to 1012
ok gutting it and doing a reflash to 3.04... will see what happens.
odin
get odin 3 1 click downloader. put your phone in download mode. then click Start. that will reflash back to stock JF6 firmware. then once booted back up. put it back into usb debugging then hit master clear. that will completely wipe out sd and put stock firmware back on. its too easy. Now if you sent phone back in to samsung they will still know you hacked it. Because in october ATT sent a firmware update to JH7 2.1 update 1. to get it back on to be COMPLETE out of box. download samsung kies. and it will update it for you. poof. now there is an odin 3 one click for leaked captivate froyo. it looks like stock but has more options and its froyo. uses ji6 modem. works very good for me. just have to get super one click root 1.6.5 to root phone and enable app side loading.
New to android roms and accidently a I9000 rom (Ultimate) onto my I9000M. It now boots showing "Galaxy S GT-I9000M" and then changes to show "Galaxy S GT-I9000" and then stops there.
I am able to get it to boot into clockwork and have tried the restore all. But it is still messing up when booting.
How can I fix this? I am currently on a linux box, will I need a windows box with Odin?
Flash a i9000m rom, you can use heimdall instead of odin probably
Good I9000M roms?
Ok I have Heimdall and am still reading up on it. But looks straight forward enough.
Now to find a stable I9000M rom. Every reference to a I9000M rom I can find seems to be controversial, can anyone with a I9000M vouch for a rom? Is there a list of I9000M roms somewhere? Is there a link to the rom files of the official BMC 2.2 release? 2.1 is fine too don't really care just want to get back onto something stable for now.
i9000m is bell right ?? canada ?? if so try this http://forum.xda-developers.com/showthread.php?t=845558
that should do the trick
You can install I9000 roms on the I9000m, I have done with no problem maybe you install just got corrupted, reinstall the stock rom then flash the one you want over it. I know that darky and Docs roms work very well with our phones, I m on Darky's 9.2 with bells JL2 modem and it works fantasticaly.
Sent from my GT-I9000 using XDA App
azzledazzle, yup it's a Sasktel phone but they get all their phones from Bell Canada anyways.
So downloading the I9000UGJK3.tar right now. I guess what I am still not understanding is what all would have been overwritten by the Ultimate firmware when I flashed it in ClockWork Recovery? And what all am I going to need to overwrite to get back to working? I was on stock 2.1 when I flashed Ultimate. I900UGJK3 is a 2.2 rom as far as I can tell.
From what I have found the firmware would replace all sections of the PDA/Code: rootfs, kernel, param.lfs and the recovery partition.
Are the PIT files some kind of partition table? And would Ultimate have touched them?
Still can't find a good explanation of the CSC. Anyone help me out on what that actually is?
I am unclear if the boot loaders would have been overwritten at all? At least one of the went unwritten as I still have clockwork recovery. Is the ClockWork Recovery contained in one of the boot loaders or does it get a separate partition that the boolader just points to?
Modem is the radio firmware, I assume.
stock firmware will erase any traces of modifications including root lagfix apps anything you have done... if the firmware your downloading comes in 3 files use PIT and Re PARTITION in ODIN, this will completely restore the phone to the day it was made.
if it doesnt come in 3 files and only comes in 1 PDA file DO NOT USE PIT OR REPARITION.
but flash anyway and see what happens, ideally you will be needing a 3 file firmware.
but i only use I9000 I have no idea how the other SGS spinoffs work sorry.
Here is a link to JL2, the latest 2.2 ROM for the I9000M. I use it and I am very happy.
Working again
Ended up on JL2. Thanks to everyone for responding.
There were actually 6 files when I untarred (rootfs, zImage *kernel, param.lfs, secondary bootloader, CSC cache and modem). But it was pretty obvious how to load it into Heimdall. Turns out that part of the update was the second bootloader. Probably what was giving me the issues before.
Still curious if there is a developer or some documentation that can put a little bit more of an explanation of exactly what the param.lfs, Sbl.bin and cache.rfs (CSC) all do. I want to learn and become less of a button pushing monkey.
My LG E400 shut down and won't turn back on
hello
i think i had installed a wrong rom so my phone turned off and dont want to open again even in recovery mood
any help please
I have successfully installed the Roto/JMI v2 Rom on my Verizon Galaxy Tab.
It seems to work, but somehow I lost my modem. Where can I find the CSC/Phone firmware to reflash using Heimdall?

did you roto back first before anything?
Here is the modem.bin file extracted from my Verizon GTab. It worked to fix my modem when I mistakenly placed the zImage file in modem slot for Heimdall.
Used 7z to compress. Just uncompress and use Heimdall to update.
Let me know if this works for you...
when I use that modem.bin, heimdall with go to install it then sit at 100% but doesn't actually install it. It locks up, when I restart I get the phone exclamation mark computer error picture.

Hmm, that shouldn't happen. How long did you wait? Heimdall will wait quite some time (sometimes 5 minutes or more) for the phone to respond. If the phone doesn't respond in this time then you should see an error message.
Anyway if the modem flash did actually make it to 100% then you should be able to use the command line tool directly to just get rid of the phone exclamation screen:
heimdall close-pc-screen

Thanks for your response. I ended up re-flashing the Stock Firmware, and it worked.

Golden422 - How did you do this, what files did you use?
I have the exact same problem you were having, no luck for me.
I still stuck on airplane mode with no GPS.
If it means anything, under "About device" I have unknown Baseband and Hardware versions.
Thanks in advance.

Same. I have no 3G network. I am also stuck at the 100% loading screen. Help would be awesome.
You guys should check out the Gingerbread leak for VZW that Oldmacnut posted in the development section. It's a full stock GB rom. Otherwise I'd recommend his Better Than Life rom. The stock GB should get you back up and running, then you can figure out what you want to do from there. There's also a stock Froyo rom floating around here for the VZW tabs as well. The Sprint rom breaks the VZW tab's 3g, known issue. You always want to try and get the stock rom for your specific tab.
The Sprint install breaks my modem? How unfortunate. Anyway how do I put a band-aid on it to fix it? Lol
Hope I don't have to send it back to get it fixed...

Oldmacnut is my hero! Love the GB release too.
I'm running Overcome currently. Is it possible to flash to a stock system from Clockworkmod, such that the system I'm running is stock?
I don't need the tablet itself to be bone stock, but I'd just like to switch back to the stock system, with none of the Overcome modifications.
Ideally, I'd love to be able to keep Clockworkmod and still use Clockworkmod to flash modified kernels. Even more ideally, being able to stay on ext4 would be great.
The reason I ask is I've been seeing some weird bugs lately, mainly with my AT&T wireless account mysteriously breaking down and not working until I reselect the APN and reboot, as well as 30 second hanging on boot, and I'd like to try stock again to see if those problems go away.
I think you can apply Clockworkmod afterwards, if you have already successfully applied Overcome. This means that you have Odin ready on your PC, drivers for USB ready and your tablet is rooted.
I applied stock_safe ROM included in Odin package to fix my freezing tablet. Lost CWM, but right now I am looking how to apply it separately of Overcome.
edit: I think I have just found it on the market, you have free and premium version. I think this guy deserves free coffee, so let's buy premium.
For my at&t tab i use JQ1, which is stock gingerbread, then i applied the CF-Root v3.3 to have root and CWM. Then I flashed Dip7 kernel for speed improvements.
I was having the lag issue too so I reverted to this set up, and I really like it.
As for the connection issue, you have your apn correct, but remind me what modem you have? Maybe an experiment is in order.

Okay, so I can flash to Overcome's stock safe (which will change me back off of ext4), and then using Odin flash one of the stock firmwares, and then apply CF-Root to get root/CWM. Does that sounds right?
It's actually pretty disappointing that AT&T still hasn't released or even announced its own Gingerbread update yet, which I hadn't realized while typing this, since I had really wanted to flash back to stock to fix the AT&T connection issue, but it may still work on other firmwares. Going back to Froyo seems like too much of a step backwards.
I'm currently on the KM2 modem. What do you recommend?
Flash stock safe then flash CF root, overcome kernel (only kernel), or Koxudaxi or dip7 or whatever pleases you then flash the modem that works best for you.
So my mom is using my "old" Captivate. When she was on the beta version of Android 2.2, the data and cell connection kept turning off and she would have to restart the phone in order for it to work again.
I updated the phone by flashing Android 2.3.5 (I897 UC KK1). It was working totally fine and then it started to have the same issues as before.
I was wondering if anyone could be kind and help out.
If a new modem needs to be flashed, how do I do that?
As of now, there is NO root on my mom's phone since she doesn't care about that stuff.
All help is much appreciated!
PLEASE? Someone has to know......
You can try other modems. You need CWM to do that. Flash a kernel with CWM and then flash from the huge list of modems that can be found at Oxicottin's thread
I believe you could also extract the modem.bin from those zip files. You could then place that modem.bin in the PHONE slot within ODIN and just flash the modem itself without ever changing the kernel.
Please someone correct me if I am leading him wrong. This would require him to only flash with ODIN once and still keep his stock kernel.
You are right that can be done as well.

It's been so long since I did it that way I was trying to remember if I was correct. I've been spoiled by all the DEVS making CWM packages.
