GB downgrade to Froyo Rom - Galaxy Tab Q&A, Help & Troubleshooting

I am looking for froyo firmware for my bell gsm p1000. I was using GB overcome rom and had some wifi and BT issues. I wanted to see if it's a GB problem. I also tried ICS, but didn't like the battery performance. I was on the samfirmware page, and there is a bunch of Froyo roms that's got no country code, I don't want to end up with a locked bootloader. Can anyone suggest a European Froyo Rom that also comes with phone software?
Went back to stock GB. Seems to be fine now.
I was on Overcome 4.1 with Red pill kernel for 2 months, then wifi started to malfunction intermittently for me.

I think you gave up too early.
Try overcome 4.1 with Red Pill kernel.

[Q] Darky's rom v 7.7 reception issue

hey guys , i have flashed several rom and i really like the look and feel of the darky's rom however i have really bad reception issue. sometimes at home where i usually have full bar i have no signals at all , or last night i was traveling to Oklahoma city with my friend who is running captivate on stock rom and he had full bar while i had no service at all ! any idea what i'm doing wrong ?
Usually better to ask in the darky thread , but anyways.
Did you flash back to stock and then upgrade to darkys or did you upgrade on top of a previous rom? If the latter, flash back to stock and reinstall.
If the former, try a different modem. I am not using the modem or kernel that came with darkys rom. I am using the kernel with speedmod and ugjl2 modem and so far I have great reception. Of course that isn't saying much as I always have great reception using my cell device (can't think of its name atm.)

You are running the I9000 version and not the captivate port. This alone wont cause problems if you have the reoriented kernel but the jpy modem you have will. I believe it does not have the 850 band. Flash a different modem from the modem thread in the development section and you should be good to go.
If im mistaken please forgive as its 7:30am and I still haven't slept yet.

thanks for your reply ! well yea i did one click odin to stock 2.1 and then flash this using this guide http://forum.xda-developers.com/showthread.php?t=868262
and http://forum.xda-developers.com/showthread.php?t=808286 flashing xcaliburinhand's latest reoriented kernel (odin version) with voodoo (I9000_reoriented_v2.3.0) so i'm not sure what is the issue here ... can you all guide me what modem should i use ? i was actually thinking about the same thing because i use to have a phone that didn't have 850 bad and i had this kind of issue ! so any help of how and where to get a modem to flash will be greatly appreciated !
I personally use JK4. A lot of people find that JL3 works better for them. Either way at the moment these are the top two modems available. Both can be found here http://forum.xda-developers.com/showpost.php?p=9134296&postcount=2 and are flashable via CWM.
Also next time you are going to flash a version of Darky's just use this thread http://forum.xda-developers.com/showthread.php?t=890429 or any one that ytt3r starts because he ports them over to the captivate and you don't have to worry about messing with kernels or anything not working properly.
thanks i'll try it next week , since i'm running Axura 2.2 and so far i like it

Questions about Bootloaders, Kernels and Modems

I am new to Galaxy S but have had experience with roms, kernels and radios from a G1.
I started with Samsung 2.2 firmware and rooted it using Cyanogenmod wiki page and flashed the latest MIUI. I know kernels change speed and include Voodoo colours and sound for Galaxy S. I also now radios can change signal and gps accuracy.
1)Are modems the same as radios and if so where do I find a list of them?
2)What is the best bootloader and why does the Gingerbread one not have sd cards work? Also what else doesn't work?
3)How can I check which radio I have and if I flash any bootloaders how do I check that?
Radio, Modem and Baseband are all the same thing. You can check which one you have by going to Settings >About Phone and checking the Baseband Version.
A new modem is easy to flash as a zip file from Recovery and you can find lots of them by searching in the Dev forum, however make sure you flash a modem that is for CM7 since you have Miui installed. For guidence you can search for Modem in the Miui or CM7 thread in the Dev forum.
As for bootloader, there is no way to check which you have, but as you installed Miui directly over 2.2 you should have the froyo bootloaders. CM7 and Miui were designed for froyo bootloaders. Some people say that GB bootloaders have better battery life but if you have GB bootloaders with CM7 you can't access you external SD card and other things may not work properly. I would suggest staying with froyo loaders for now and seeing how it goes.

I have read this:
http://forum.xda-developers.com/showpost.php?p=9579987&postcount=11945
but I don't know if it still JPP is the best radio as this was back in December. For people in the UK what would be the best overall radio?
can anyone answer me which is the best CM7 modem for ORANGE ROMANIA? tks
Try jvp or jpy, I'm on orange uk, insanity cm and they both work fine for me don't forget you need cm7 modem, there are 2 threads in dev for this

About bootloaders
I have a SGS GT-I9000, and following
directions from ROM kitchen, I installed a Froyo 2.2.1 version.
It's I9000XXJPY with 2.6.32.9 [email protected] #22 kernel
and it says Rom kitchen v11.1-ZSJPK.
I wanted to install a Gingerbread version from ROM kitchen as well, but it says I have to make sure I have at least JVH bootloaders. Ummm, do I ? And what to do so i could install a gingerbread to my SGS ?
I installed a 2.2.1 froyo also from ROM kitchen I9000XXJVO with 2.6.32.9 [email protected] #22, build number XWJSD, hoping i'll install newer bootloaders with it.
But, i had problems with messaging so i'm gonna have to revert to previous one.
Do i have proper bootloaders or not and what could happen if i tried to install Gingerbread and don't have proper bootloaders.
Thanks in advance

[i9000m] kernels for 2.3.3 on canadian firmware

Can I flash a kernel meant for i9000 international to my i9000M?
If yes, why would speedmod kernel give me a boot loop?
Is there a solution for the boot loop?
If not, are there currently any kernels that work with I9000M gingerbread? I'm on 2.3.3 UGKG3.

See the discussion in the general thread on moving to jvr and using kg3 as modern and csc. Tornado kernel and rom will work for you.

Please don't take this the wrong way Igsshedden, but if people ask about kernels for KG3, they don't want to be told about custom ROMs. I have been following the discussion in the general thread, and many times the question has come up about custom kernels for KG3, and you respond with "try the tornado kernel".
I want to let you know that I have tried it, and it does not work. It bootloops my i9000m. Why? Because I am still running the KG3 PDA, and don't want to switch to something else like a leaked/custom JVR. There are many valid reasons for wanting to stay on the official KG3 Rom, and not to flash a custom Rom.
Perhaps in the future, when the question comes up, perhaps you could respond with a little more information so as not to confuse people. Please don't mention the tornado kernel as an option without mentioning that it requires a custom rom to be installed as well.
For example, "Currently there is no custom kernel that will work on UGKG3, except for the rooted stock kernel. If you want advanced features like CWM recovery, Overclock, Undervolt, or lagfixes, you may want to switch to a 2.3.4 ROM, like JVR or custom, that have kernels designed for the rom.".
I'm sure that would give people enough information, without confusing them about compatibility.
For example, "Currently there is no custom kernel that will work on UGKG3, except for the rooted stock kernel. If you want advanced features like CWM recovery, Overclock, Undervolt, or lagfixes, you may want to switch to a 2.3.4 ROM, like JVR or custom, that have kernels designed for the rom.".
very well worded: my replies were not meant to confuse anyone and I appreciate your clarification. I had conflated the question with a solution and not supplied the intermediary explanation.
One point of clarification, however, JVR is not a leaked, beta nor a custom rom but an official samsung firmware. Hence, given the accepted difficulty in rooting or using a kernel for KG3 my suggestion (consistent) has been that users of the KG3 modem and CSC move to the latest available official firmware, namely JVR.
Should they then wish to add a custom kernel or custom rom to root that stock JVR, my suggestion has been that Tornado would do that.
Also, to further clarify, use of the Tornado kernel does not require use of a custom rom but can indeed be used with stock JVR Samsung rom.
Eventually, Bell will catch up to the rest of the Samsung user base and 2.3.4 will be released in Canada: but why wait?
Why wait?
I can't tell you a reason, other than that I boot loop when I try and flash. I can't flash any i9000 international version without a boot loop, in fact.

Thanks for your response. I didn't intend to imply that JVR was a leaked Rom. Initially when it came out, it was a "leaked" rom from darky's team, and has the JVQ CSC. Eventually it was released for Swisscom mobile with a specific CSC for SWC region. So, I do understand that it is an "official" rom.
However, I'm still concerned that it doesn't seem to follow the naming convention for official roms. In fact, the only ones that seem to follow the naming conventions are the Bell KC1 and KG3 roms from this year. They start with "K", the 11th letter of the alphabet, to represent 2011. The second letters were "C" and "G", the 3rd and 7th letters of the alphabet, to represent March and July (the months in which the roms were made).
So, if this is the convention that roms used, then why do the european roms still start with J, if the first letter J is supposed to signify 2010? Any thoughts on this?

I have a sneaking suspicion that Bell will never get a 2.3.4 or 2.3.5 rom on the SGS. Remember, we never got 2.2.1 either and were stuck on 2.2 since December 2010

I've seen in other people's signatures, that they have the i9000m with a JVR rom, and KG3 CSC/Modem. So if you're bootlooping, it may be an incompatibility with the bootloaders and/or kernel. Honestly, I'm not 100% sure of the process when you are flashing over KG3. Since you already have gingerbread bootloaders, I'm not sure if the rom that you are flashing via odin must have bootloaders in it or not. Like I said, it may be an incompatibility with the i9000m bootloaders vs. i9000 bootloaders.
This is one of the big reasons that I have withheld flashing a non-i9000m rom onto my phone. I try to avoid changing the bootloaders when I flash roms, since that's the only sure way to truly brick your phone if something goes wrong. Maybe I'll just try to make my own rooted kernel with CWM for it, if I can figure it out.

I9000M Questions

I have a Bell (Unlocked running on Telus) I9000M SGS and I have tried many different ROMs to try to get the GPS to work, but there is always something about the ROM that makes me change.
I have tried ICS as well, but that didn't work at all. I have tried ROMs from Europe (JVR and JVS) and while the GPS did work, the phone didn't have the reception it should have had. I am now back on stock GB 2.3.3 - UGKG3.
Has anyone ever solved the GPS problem with the Bell ROMs? Has anyone used any other ROM that worked as well as the stock ROM, but with working GPS? For those with an I9000M, what is the best ROM/kernel you have used.
Another thing, I have had the M/B replaced due to the dreaded internal memory problem and with the non-existent GPS and the lack of Android updates to Canada, will you get another Samsung phone? I would love the Note, but can I trust Samsung?
Thanks for the info,
Ian
I have a i9000m through lleb and I have been using this modem i9000 ugjl2 and my gps is perfect.
And if your using google map I also find if you change yout scripts from N-America to europe you'll also get a faster gps find.

Upgrading from Froyo to ICS

So my old phone is no used by my sister and is still running Fusion ROM on Android 2.2. For some reason the wifi is no longer working and I figure I would upgrade to ICS since I am redoing things anyway. I read another thread where a guy flashed straight from Froyo to ICS and is running ok, but I remember going from Android 2.1 to 2.2 was a pain and I had to wipe, flash back to stock, flash new bootloaders, and then the Froyo ROM. I would assume going all the way to ICS which has major changes would also require something complex but just want to be sure about the process. So am I supposed to use Odin to flash stock Gingerbread and bootloaders before I upgrade to ICS? Or is it really fine and all will work if I just flash an ICS based ROM from where I am right now?
I am thinking of flashing the SlimICS ROM unless someone can tell me a reason why that ROM is not very good?
Currently the phone has the 2.2 firmware, i897UCKB1 baseband, 2.6.32.9 kernel, and is running Fusion 1.9.8 ROM. I am not sure on the bootloader version, but I have a file on my PC from a long time ago called "galaxys-bootloader-JVB.tar.md5" that I think I probably used to update the bootloader all that time ago when I moved to Froyo.
See TRusselo's "[Guide] How to flash ANY Captivate Rom from Stock (including ICS)" that is a stickied thread in the Q&A Forum...

So, your saying I should flash to stock and then flash to gingerbread before moving to ICS then?
Nope. Just Read the OP of that Guide and all will be clear... Just Read the 1st sentence of that OP...Lol
