[Q] SGH-T849 T-Mobile to Gingerbread and back to Froyo: Honeycomb?

1.5 years ago I bought in the US a T-Mobile Galaxy Tab 7" with Froyo as standard. Last year I decided to upgrade to unlock it and then to upgrade to Gingerbread by following the guides on the sire, all good. A few weeks ago unfortunately I poured a glass of red wine over it, and the Galaxy entered in a boot loop with serious issue on the on/off buttons. After trying to revive it I brought it to a Samsung service where very nicely they cleaned it and gave it back to me in T-Mobile Froyo status, all free of charge. I would like now to reunlock it and upgrade it, so question:
- can I upgrade to Honeycomb? from what I read here not that stable plus my tablet not powerful enough
- If not, is there what is the most stable Gingerbread release in order to be able to make phone calls? I've searched extensively on the site but I'm still confused at all the options.

wow. how generous the service center is.
There is no Honeycomb for our tab. There was an RC version but I think all links are dead.
There is CM9 ICS if you want to try, it is still a Work In Progress, you can try one of the nightly builds.
For stable GB there are plenty. Overcome 4.1 is very popular. I am using Acudroid. There is also Hyperdroid.
I have a T-mobile tab using JPZ modem, but I am in Australia. I can use voice call and 3G.
But if you use this modem in T-mobile network, if I am not mistaken you can make call but with 2G data only.
If you keep your original modem, it will be no call but you get 3G (that is my understanding)

Definitely!

Thanks priyana, major differences between Overcome & Acudroid?

Well, I live in the UAE, so not really care about T-Mobile. I searched a little bit online, am I correct to assume that Overcome is basically a 2.3.6 Gingerbread with improvements and very stable?

Yes. Very stable.
Somehow I got unexplained batt drain on Overcome 4.1 no matter what I do to recond the batt.
Just switched to acudroid and it is fine, although acudroid doesn't have it's own kernel.
Btw, what is UAE's gsm/hsdpa freq.
Here I have like europe and SE Asia. And JPZ modem is suitable for it.

At the end I followed your first advice, and installed Overcome. Have to admit that the instructions are fairly easy (apart from the link to the pics which are outdated), and it seems quite stable.

JPZ is also good here, I reflashed that modem after finishing installation with Overcome, and now making calls works fine (haven't tested data via 3G yet, but don't really use it, you got wi-fi everywhere).

It is always good to try out Overcome.
From there it will be easy to try out CM9 or AOKP ROMs.
Have fun.

[Q] Help with 3G connectivity issue

Hey I need help with my phone's network compatibility
My sister gave me her old Galaxy S I9000 and everything worked fine with her she never lost reception
But when she gave it to me i immediately came to this forum and flashed it to ice-cream sandwich 4.0.4 the Extraordinary kernel i think
And i noticed i could only get 2G signals
i then flashed the rom to aosp same problem then aokp same problem
i now have Slim because i prefer that but it still has the same issue
i looked online about this problem i haven't found any solution
i did find one tutorial that enabled you to change the S to pick up a different band of network that was previously locked or something
i tried that and it didn't work i couldn't open the settings to it
any help is greatly appreciated thanks in advance

[Q] costum roms and slow wifi speed?

this thing bugs me a lot. why costum gb roms have slow wifi speed? i tried cyanogenmod 7 - slow wifi, then tried cm9 - wifi is ok. but games are very laggy so i'm back at gb with gamerz rom but wifi is slower again, but acceptable. so i'm thinking about restoring original wifi drivers/settings to have normal speed wifi but i don't know is it possible and which files i need to overwrite. to mention i don't have slow wifi, it's 1 MB/sec download, and it needs a few secs to load google, when i'm at ics or stock gb it loads instantly.

Its strange you should mention this as I only got this phone today and I flashed a custom rom and my hsdpa speeds were awful , like 15 k a second max, I tried a few others same result, im now back on stock and its flying, i know it isn't WiFi but its got to be related in weird way !

Custom Rom uses modem that might not always be the best for your region. If you think your stock Rom has better speed, try to download the modem file for that rom and flash it after you flash the custom rom.

Yes I think that must be true ,I found some interesting information and modem files here http://forum.xda-developers.com/showthread.php?t=1548815&page=46 its seems there isn't anything or any problem that somebody hasn't solved lol, I love this site !

ok, i'll try first that modem from nexus s, if it won't work better then i'm going to flash original modem files
edit: it says for ics, cm7/9 and miui. wil it work on gb? i'm not planing to migrate to ics.
edit 2: nope, nexus s modem not working, gives me error.

Yes these are only for cyanogenmod roms and ics I believe, I'm not sure if the modems can be extracted from the original firmware for use with gingerbread but hopefully there will be a guru who can tell us if it can be done and how to do it, maybe there are some modems for 2.3 on here somewhere, I will have a look as this is something I would like as well ! I would migrate to ics but my data speeds are awful on it!

The guru phone god xsenman has got more collections of phone software than samsung and apple and nokia combined lol and he has posted a really useful link

i'm back to stock gb modem. maybe i will try again cm7 with nexus s modem. maybe. now it's near perfect. good network signal, fast wifi, and most games don't lag. nice.
only thing that lure me back to cm7 is bottom status bar. i like that.

Network Signal Low since 4.3

Hello,
I have a Samsung Galaxy s3 and ever since going to 4.3 my signal strength for mobile is weak, very weak.
I have re booted phone, taken battery out, tried different modems but all with no luck.
Has anyone else had this issue and successfully fixed it?
Cheers

Got the same issue, as I flashed the new Alliance Rom on my S3 LTE. Most time I had just one of five network points.
So I did another Full Wipe, and used the Boeffla Kernel with stock modem.
Got slight better results, but there are always lil interferences while talking. Probably its the bad network by german T-Mobile.
Regards

I have the australian optus version and signal where I live is really crappy on 4.1.1 I upgraded to 4.3 the newest one from hong kong (the one my rom is based off) and now I have found that the modem and ril driver in that version is giving me stronger 3g and 4g signal

I am in Hong Kong with the following
JB 4.3 XXUEML8 rxtreme JB 4.3-V2.0
Hong kong modem ZHUCMK1
Stock kernel of XXUEML8
My house is at 35/F of a building, my phone will have signal as stated below:
LTE/WCDMA/GSM signal with 2-3 out of 4 bar
WCDMA/GSM signal normally full 4 bar

Hey everyone I am back developing again haha Noticed this myself with 4.3 so I have looked into it and noticed something very different with 4.3GSM RIL class files. They are are all reverted to the standard GSM ril type files, where as on all previous generations have used QMI based RIL.
I have created a patch that I am about to test and if I have any luck I will upload it here for you guys to try out for your selves. It should work for other countries as well so long as you have noticed a difference in the RIL types between 4.3 and 4.2 or earlier? If not then I would suggest leave things as they are and flash a new modem.
I am on Optus and I am comparing the first 4.3 release to a stock Optus Android XXALI5-OPS, does anyone know what the version number is called from the OTA update for Optus?

I have the same problem. My wife has an I9305 and I have an I9300, both with 4.3, my signal is way better and usually get H+ internet and she just gets Edge.
Any progress on the fix? I would love to have the patch, or even just the information on which files to change and what to change.
Thanks
