Hi. I have a c6806 I bought from Sony Store and updated to 4.3. I downgraded back to 4.2.2 by flashing it with Flashtool. I downloaded the FTF file from the XDA forum. 14.1.B.1.532
After flashing it, I confirmed its now back to 4.2.2. However the problem is that I can no longer connect to AT&T. It doesn't have a signal. I don't know what to do. I looked under Mobile Networks and there is nothing listed under Access Point Names. Any info on what I need to do to get this to work again? Any info would be much appreciated. Thanks :good:
NVM sorry. after an hour of researching, I found out that I need to flash a newer rom and got my LTE connection back. If you downgrade back again, make sure you uncheck BANDS in Flashtool. In case someone else runs into this problem.
I'll just post this thread here in case anyone else stumbles across this thread with the same issue.

I was having exactly the same problem and was able to fix that by flashing a newer ROM

First off please let me state that I am aware that I am not any sort of expert when it comes to this sort of stuff. I might use incorrect terms and say things in a way that displays my ignorance to these extremely technical topics. I am have some good common sense and problem solving skills though so if someone were to offer me some help I can probably 'figure it out' by thinking critically.
I have a X10A with AT&T and was too impatient to wait for SE to come out with the 2.1 update here. When the Nordic update came out I was one of the people that rooted and de-branded my phone so that I could get 2.1 on it. Everything went fine and nothing else seems to be wrong with the phone except the boot loop problem. I can not seem to find a definitive answer as to how to fix this on any forums or anywhere else on the internet. I updated it with SEUS and it did not fix the problem.
Since having done this I have read that all the user data must be wiped before rooting/upgrading otherwise one can get stuck in this boot loop (http://www.xda-developers.com/androi...or-xperia-x10/). I don't know if that is what happened to me or not???? Any help someone could offer would be very much appreciated. Thank you.
So you flashed to nordic when it came out but you just now get a boot loop?
Not sure what happened but I'd say try flashing it. Since you are in a boot loop & can't power on & turn it off to get into flash mode, try THIS
I suggest 2.1.A.0.435 X10a 2.1 Global Generic, there's a nice guide HERE on how to install & optimize it. From there you can install a custom rom if you want or just wait for the 2.3 update from SE or see what our devs come up with in the meantime...
At&t will never give us an update... one of my many complaints with them... I am dropping home & cell services ASAP...
Yes I flashed to Nordic when it came out. I have been in a boot loop ever since. I am just now posting this because I have not had time to deal with it. I had insurance on the phone and just got another one instead of fixing it. I will try your suggestion and let you know how it works out. Thanks for the help!

Do you flashed the correct baseband to your ROM?
Maybe you have to install correct baseband with flashtool.

how to flash my SGY and where i be able to get firmware for my SGY? plese help me, i'm very confuse...
I loaded the P7510 root files on it (BAD IDEA for anyone reading).
I tried to "re-stock" it with the P7500 stuff and it wouldn't work. (when I get home I will try to find the right .pit file and try it again)
I tried to push a new rom with ADB and flash it and so far no joy.
If anyone has any ideas I am open to them.
if anyone has the t-mobile 10.1 tab.... CWM recovery seems to work. I need a full system backup to restore my tab. If anyone can help it would be appreciated.

What version of the CWM do you have? I found that 4.x and 5.x versions create different file types for the nandroid backup and they are not compatible.
I can create a backup for you tomorrow for any of the CWM, just tell me which one you need.
[EDIT]
I have a unbranded 10.1 3G and the backup would be from a modded Overcome ROM, but at least you would get the tab back to work.
[/EDIT]
I think it needs to be the T-Mobile ROM. I can flash stock roms for the P7500 if they are the same. Anyone else try any roms on the t-mobile tab?

Didn't the T-Mobile just release? Your the first post I have seen for it. What the model? P7500 or something else?
Also, FYI or not, this does not belong in the Dev section. Please read the rules for posting.
http://forum.xda-developers.com/announcement.php?f=1053
It was meant as a combined warning and cry for help I figured since this is where everyone comes for info on root... the warning should be here too. The model number is SGH-T859
you may need some one else to do a t-mobile rom dump, and reflash either through cwm or odin. Did you check the samsung firmware site for a recovery image? As a last resort, you could exchange it for a new one. And of course make a good backup in the future to go off of.
BTW, that is odd that your model number is so different from the normal gt-7xxx. Just to be sure, this is a galaxytab 10.1 or 8.9, right?
Yeah it is a 10.1 .... t-mobile always has a new number but it does surprise me that the p7500 stuff isn't working... I will try again tonight. If anyone has the T-Mobile 10.1 tab please send me a system backup

Moving to General
Not surprised the model number is different considering the LTE from Verzion is different as well.
ok so I got it to work with the 002001-Overcome_CWM_Recovery_v5.1.2.3.tar here
I am making a backup. I couldn't get the "re-stocking" part to work. It looks like we need a .pit file. But if you want the CWM recovery that should work.
So far my wifi hasn't come back :'(
I am going to try a few more things and report back
Wish I'd seen you're posts sooner. I pretty much followed you right off the same cliff. I was hoping that an easy solution was at hand. I'm much more a noob at this stuff, and am having trouble communicating with the tablet at all, much less doing anything to problem solve it. I do have CWM v4.0.1.4 working and would be happy just getting the stock kernal back on it. Guess I have a lot of reading and learning to do this week.
If anyone can help, I'd (we) would really appreciate it. I have a long hospital stay coming up on the 14th and this tablet was going to make it a bit more bearable. Is there a way to remove CWM so I could do a return to T-Mobile? Just a thought...
Thanks for any input.
Hmmm this is for the new 10.1 4G model? I have a stock one I had been waiting to root til I could find out if existing methods worked or not
can u pls send me your stock boot.img?
would like to add support for it.
thx.

Yeah, don't root it yet. The current root methods don't support it. Man, if you could provide pershoot with an image and/or me with a nandroid backup that would be fantastic. I don't mind waiting for the excellent developers here on XDA to do their stuff (it's always worth it), but I've got about a week to get mine up and running again.
Thanks for whatever you can do.
I got mine to root just fine, using the process in the stickie. I used odin and then cwm to install root. Stayed on stock rom and used Ti backup to uninstall bloatware. I am happy as can be

point me to the recovery image you used, I'll dump a nand and upload it (asking for link just to ensure you get exactly what you need)
HI
Hi, I have a model like yours, t-mobile model: SGH-T859, if you send me a step by step I can send the files you need to get your table
Anyone has a solution for this right now?
I am stuck with the same problem
Thanks
Thanks for posting this info, I am sure this post has saved a lot of ppl from jumping off the same cliff.
Hi All,
I'm totally new to rooting and to be honest I never planned to get into it and especially not in this way.... please read on....
I bought a 2nd hand S3. The original owner told me it had been unlocked from Vodafone UK, but no further modifications.
So the phone arrives and I turn it on and the first thing I notice is UltimaROM asking to download their latest v9 ROM. I see other apps installed like SuperuserSU, Headphones shortcut for SGS3, S Note etc... so I suspect the device has indeed been modified. Seller tells me it's only been unlocked and nothing else. Also, comparing to a work colleague's stock S3, my phone has a different appearance (different battery % icon amongst others...), I see Nexus 4 wallpapers are available, JaiThemes etc... all looks a bit fishy to me.
Also phone does boot into recovery mode into CWM...
So I start reading a little bit, I've downloaded Rootchecker - says phone is not rooted.
All I ever wanted was a stock S3, no interest in rooting for now. Could someone please advise what I can do to get back to stock and have it unlocked? I know there are guides to un-root a phone, but rootchecker says my phone is not rooted, and I have no original backup, so I don't know where to go from here....
Any help or guidance is appreciated here...
Check the basics, there's a guide on flashing a stock ROM.
The seller is definitely lying to you

Thanks for the reply.
If I find a Vodafone UK stock ROM, will I then lock the phone back to Vodafone?
Thanks
Don't think so, but why would you get a vodafone ROM? Just get a universal one

Thanks for that, I will look for a universal one.
I've been looking for a bit, but I can't find the 'basics' section you mention in order to flash a stock ROM.
I have searched the forums, and people have mentioned ' I flashed a stock ROM' but I need to know the steps to do this...
Also - has my warranty been affected? If yes and it is now invalid, will flashing a stock ROM solve this?
Again, any help is really appreciated here.

hey Nikhil Dhand!
thanks for offering to help buddy i greatly appreciate it.i finally fixed it following this
http://forum.xda-developers.com/showthread.php?t=2679600 post #3
and did a factory reset WITHIN the phone itself and im back up and running.im usually pretty good about keeping up to date on ota updates,rooting,flashing etc.... just been busy with the house and got out of the loop and paid the price.
again i greatly appreciate you trying to help me out.
Hey everyone, first post here so please take it easy .. I've read a few older posts but having trouble knowing I have the most correct updated files.
I'm generally not the worst with techy stuff but I'm needing some basic walk through to flash my phone to the unlocked version of someone can help me out.
I have a US cellular branded s9+. I recently transferred it over to total wireless.. And it seems I've gotten most things working for the most part. However, I lose Data when making phone calls. So even though my volte setting is turned on it appears it's glitchkng up... I'm assuming because it's the uscc firmware. Based in what I've read on reddit it seems flashing to u1 is the best bet to fix issues like this.
I've read some threads and I'm not really sure which version of Odin I need and which firmware is correct.. If anyone can help this rookie out I'd be greatly appreciative.. And maybe confirm flashing is the correct way to go about this??
Thanks in advance!
All u need to do is flash to TMobile and your all good to go. I was using a sprint variant of it and I would also lose data.
Flashed it and now I have all the perks Wifi Calling / VoLte
