galaxy tab downgrade to froyo pre-rooted no bootloaders - Galaxy Tab Q&A, Help & Troubleshooting

can anyone help me find either the jmk froyo software that i can put onto my galaxy tab gt-p1000 that does not have the bootloaders or. . .
try and find the correct files to install the final release of overcomes froyo so i can put the overcome 1.4.4 or it may be 1.4.7 onto my tab.
the issue i'm having is battery life on the tab is a bit rubbish! if trying froyo does not solve the issue then i'll sell it and buy the galaxy s instead, i've tried battery calibration and different gingerbread roms but the battery life is not good enough.

[Q] Galaxy S ROM + Lag fix

Hi guys,
I have the Galaxy S on T-Mobile and have come to the conclusion T-Mobile will never release the 2.2 Froyo update - I'm looking to root it instead and put on one of the lag-fix's.
Can you guys recommend me the best guides for the following :-
Rooting the Galaxy S
Updating firmware to 2.2
Lag-Fix
Thanks in advance,
Gav

If you really want 2.2, best options are:
Firmware JP6
Voodoo lagfix pre-3
CF Root
In my opinion anyway!
If you can live with 2.1, then JM9 or even JM8 with voodoo lagfix beta 5 is your best bet.
With both, I like Tatuyama's ROM, I find it the most stable. The only competition really is DocRambone.
and this has what todo with DEV?
Firmware JPA
CF Root
Voodoo lagfix pre-3
here is what i am using now

[Q] Flash XXJPY Darky to XXJVK Stock

Hi,
I currently have Darkyy's ROM on my Galaxy S but I'm not very happy with it (bluetooth doesnt work and so on...).
So I want to install a stock firmware... 2.3.3 to be exactly.
I just found the Link in the Thread "Stock Firmwares..." but the filename is "I9000XXJVK"... my current firmware is "I9000XXJPY" - so is this a problem?
Would be nice to get an answer soon!
Thanks!
Which Darky Rom are you at? You should realy try 9.5 its the best ROM Darky has ever made.
But back to your topic, you should flash the JVK with bootloaders I guess or you will have a creapy screen at the boot. Stock JVK isn't a final Gingerbread. Its still beta but very stable.
Sent from my GALAXY S 2.3.3 using XDA App
no problem. just remove the lagfix and follow the procedure step by step.
if you want to be extra safe, you could flash back to stock samsung rom, with repartition and pit file, and then go to JVK - gingerbread.
aslong as you follow the instructions to a Tee, you wil be fine.
I'm running 9.3 and it doesnt work for me right. Bluetooth doesnt work, my music player starts random and much more...
Oh and I thought that JVK is the official one by Samsung.. so should I try it or should I change to the MIUI Rom for example (looks also good and is 2.3.x)?
i am running MIUI rom now and i have to say. ITS FRIKKIN AWESOME.
its so customisable, so completely different from samsung roms. i would highly recommend it, i have been thru every rom going, but MIUI is definately one to stick to.
quick updates, very helpful devs, issues fixed asap. overall 10/10
Sounds good so far
So I'm going to try MIUI, thanks azzledazzle!

[Q] Gingerbread Undervolting?

I am new to sgs (bought yesterday ), yesterday I have installed darky's rom v10 rc5.3.
I have read that on sgs u have to change the kernel to apply an undervolting, so i was looking for a right kernel to do this...but it seems that there are no stable kernels compatible with gingerbread with the uv capabilities, is that true?
thanks
One needs to ask Darky about his rom .
Remember Gingerbread is BETA so far .
jje
thank you, perhaps i'll go back to 2.2.1
keep on ginger
Gingerbread is a more elaborate rom, in general it works much better than any froyo rom, not to mention the battery usage. I was using gingerbread stock beta 2.3.3, and from yesterday on, gingerbread 2.3.3 ColdMod.
Yesterday I went back to 2.2.1 (darky 9.5) and I didn't see any great difference with 2.3.3 (just the browsing experience while loading pages), the main reason for this going back is trying undervolting kernel and also that for the moment there's not italian swype (that i much appreciate). Anyway thanx for the advice
Have you a problem of battery drain?

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.

Best combination in my opinion
Etc/gps.conf then edit n.america.or whatever it says there and replace with europe.pool
