Back ups / dual boot - Galaxy Tab Q&A, Help & Troubleshooting

From what i have read on the forums ( via search ) its not possible to dual boot ROM's on my SGT2 7 (8 GIG WIFI) . Is that true or can i dual boot ?
OK so if i can't dual boot ROM's can i do this :
If i was to make a back up of my current ROM and store it either on my SD card or on my laptop , will i have any issues if i flash another ROM on my tab and then at a later date recover from my original saved ROM ?
Whats the back up hold ? Is it absolutely everything physically on my tab such as games / game content , Appz and widgets and prefered system settings ect ?
Thanks.

No dual boot.
Yes backup backs up everything. Just make sure you flash same kernel to avoid restore issues.

Thanks for the information , appreciate it.

Hi... I hope this helps.
1. Enter *#2263# from the phone app and select only the GSM bands. This should (someone correct me if I'm wrong) only give you 2G data.
2. Hebrew comes native on 2.2 & 2.2.1 ROMS. I looked for a while to get Hebrew support while I was on stock, and I wasn't able.
4. Moving apps to SD is only available on 2.2 and higher ROMS.
5. I have no idea... can you write new files and still read them? Try reformatting the SD card or a new one.
In short... flash a 2.2 or 2.2.1 ROM. There are plenty to chose from in the development section.

how stop data eating my credit when i install new rom

Hi i am thinking of trying another rom out on my galaxy s GTi9000 .I am on pay as you go.last time i installed a new rom my phone automatically switched package data on and by the time i had set up my phone it had eaten some of my credit .Whats the best way to stop it from doing this..Can i just flash a new rom without installing my sim card and external sdcard ? I am guessing that by not having my sim installed it cannot charge me and i should be able to disable the package data setting before re installing my sim then add the sim back once set up.Is this correct.Thanks.
Yes i think so just flash rom without sim inside and then after the whole intro put your sim in.

Have always Installed Rom with Sim Inserted
Maybe down to APN Settings (always check to make sure they are configured properly for your Sim)
As well as Data Roaming option
If Pay as you go : use WiFi to save Data when ever you can

I never use my package data only wifi but when i installed a rom it switched package data on ..so i need to make sure it is off .I am thinking of installing your SAUROM GB JW9 v2 BLUE THEME version to try .I have tried xbean but had issues with media using 73% of my battery and draining it too quickly and getting really hot (apparently loads have had trouble with media when on jell bean etc ..back to stock rom on phone and it is now fine again.Have there been any issues on your rom ? i like to have loads of music files stored on my external sd card 32gb .
Just uploaded the JWB which is better in my opinion
Any issues if you have problems with the Rom let me know and just install as Stock Theme :victory:
No issues as of yet and try to fix as soon as possible
There is tweaks included and get Advanced Task manager which helps battery along with Power Schedle Basic
Both of these are very good tools.

Just follow my Guide on my signature to set it up ... word by word.
Basically Remove Samsung Kies all together on your PC if you have it (depending on what you need)
Reboot Computer
Install Samsung USB drivers
Reboot...and then open ODIN
Tick Re-Partition and put in PIT File then Follow Guide :good:
As long as its an i9000 your good to go!
If your Battery goes down fast or signal strength low just change the modem , will explain that when it happens

Thank you i understand now lol..Just out of curiosity if i was already rooted and had a different rom installed would i need to flash 2.3.6 again or would i not need to ?Thank you.
Yes starting to Flash any New Rom 2.3.6 needs to be flashed first then rooted to give you that Clean bug free Start point for installing any new Rom.
Then you need to Root it .
Doesnt matter if you allready Rooted with a JB or CM or the latest new GB rom still have to do it to be safe
Then follow guide

Have you checked Enable Debugging to connect to PC in Development?
Also did you install USB Drivers correctly
Is it ok when you dial a call?
Error when incoming call?
Using Root Explorer or other app Copy and Replace this File in to System / App Folder and then Reboot Phone

Also check your APN settings to make sure they are correct in Mobile networks

Help Needed With OS on Galaxy S4 i9505 Bought in Bankok

Good Morning Guys
After a lot of struggle I decided to post me and my friends problem here, I know on XDA Developers there are a lot of clever guys who might help us to solve this problem. Please note that I have a Galaxy S3 which is rooted and loaded with Custom ROM WanamLite Rom, so I am familiar with the process on how to do this and we have tried all options to fix the OS on this Galaxy S4 i9505 of my friend. Here are the details:
We are from South Africa and when overseas my friend bought a Galaxy S4 i9505 in Bangkok, he had the option between the clone and an Original, so he bought the ORIGINAL rather than the clone. Now once he got back to SA he started using the phone which wasn't network locked but we noticed that the OS version was a bit funny and that the phone was already rooted out of the BOX (Strange) so we thought he bought a clone and followed all the links on the the net showing how to determine weather its a clone or not. So we came to the solution that his phone is NOT a clone but it has a weird OS on it that we cant change/load another OS on. Here is what we tried:
1) We wanted to load a new OS or Custom ROM since the phone was already rooted, so we first tried to download the stock firmware from SAMMOBILE for South Africa and copied it to the Ext SDcard and rebooted the phone in Recovery mode. There we didn't have any option to install OS/ZIP from Ext SDcard ..... Not even under advanced. There is NO Mounts & Storage nothing, it just doesn't display any External Storage options. So this made us go to step 2
2) We thought okay lets try at least and load another custom ROM since its already rooted and see if we can fix the problem the other way around. So we installed Odin on PC and connected phone in download mode to install CWM recovery, ODIN pics up the device as "Unknown" and the port in ODIN doesn't become green. We have installed/uninstalled various S4 USB Drivers and when the phone is connected to Windows 7 PC is shows Unknown Device ...... You can access the phone Sdcard & ExtSDcard through Windows although its shows Unknown Device, but when rebooting in recovery mode it doesnt see the Ext SDcard - WTF?
This is where we gave up and decided to see if any of you guys can help or have any ideas to fix this and get a proper OS working on it ...... Cause I suspect that whatever OS is on the phone wont even receive OS updates and we want to be able to update the OS/Custom ROM for new OS versions like Android v5 thats on the way. Help would be appreciated guys
Take care

All the times I had this problem I've flashed stock ROM with Odin and I can confirm that it works. Seems that sometimes is a problem of SecPhone.apk
Thanks guys, but can you point in the right direction (with flashing the stock ROM)? Like, where do I find it and stuff...
(I don't know how I managed to root my phone without breaking it in the first place xD)

I've writed how to reflash stock firmware in this thread, you can follow up to the sixth step, and if you are interested also to root and CoCore kernel go up to tenth step (after this reboot device)
EDIT: You don't need "Re-Partition" option in Odin
No SIM card (but network OK 4 bars)
Hi,
I have a 9070P (NFC) simlocked to Orange France.
I've got the very same "no SIM card" issue after upgrading to JB via Odin (3.07) (tar downloaded from samfirmware).
Network is OK (4 bars), but "no SIM card". The SIM works fine in any other phone I have tested + inserting a SIM from a different operator does not trigger the "enter unlock code" popup at startup.
My IMEI is OK and has always been (*#06#).
Note : from the many posts I've read, it is *not* stored in /efs on this phone but could be stored in CSPSA partition.
Note : I've always flashed the *right* firmwares for I9070P (not I9070).
What I have tried so far :
* restock to GB with this tutorial : http://forum.xda-developers.com/showthread.php?t=2247604
--> No SIM card
* then flashed Orange's stock firmware with Odin from samfirmware
--> No SIM card
* played a bit lot with "secret code" *#197328640# menus. It happened once that I recovered the SIM card + data connexion then it failed again after next boot. So I'm pretty sure the pb *is* software.
It's a pitty I have backed up my "efs", and "CSPSA" partitions (http://forum.xda-developers.com/showthread.php?t=2145464) after the pb occured...
I have rooted the phone, dumped and tried to analyse modem/RIL logs, but did not manage to spot the pb...
I'm used to linux, flashing and so on but not that much of Android intricaces, so if anybody is willing to help me finding the solution I'd pay him/her a bear (or two)
Questions : does anybody know how to check CSPSA partitions ? It's content might have been damaged during flashes. As I have repartitioned when downgrading, partition size should be OK, but as I have read somewhere in xda that that partition content might not be replaced when flashing a tar.md5 that contain a cspsa image (which is the case in the ROM flashed to downgrade) because it contains the IMEI encrypted.
-> is there a way to mount and explore it or to extract the content of a cspsa image from a ROM (I've tried to mount it as ext4: failure)?
Thanks in advance !
What version of Jelly Bean you have flashed the first time?
Hi!
It was this one : Germany (T-Mobile) I9070PXXLPJ grabbed from Samfirmare (I doubled checked it was the one for the "P" version)
Any known pb with those JB upgrades?

I don't know if this version has the simlock, maybe your phone doesn't recognize sim card because you have updated with Odin from a simlocked GB to a non-simlocked JB or with simlock from another carrier
Hm, did you try to do factory reset? People had problems with signal if they do not do it after GB>JB.

I restocked to original ROM : still no Sim card + if the pb was simlock, it would ask for unlock code whereas it just say "no SIM card".

Yes, I did factory resets, cache wipes, dalvik cache erasure multiple times (like 20) : no dice.
Does anybody know how to activate and analyse modem and RIL logs (and manage debug level) ? I think it would help find the root cause faster than "trial and error" + decrease the risk of bricking.

Right, as you said maybe the problem is really the CSPSA because simlock infos are stored in this partition, seems that there is no way to unpack or to see the files contained in it, if you try to reflash Jelly Bean using repartition?

- Reflash Jelly Bean with repartion : already done without success + JB ROMs (I've seen until now) do not contain CSPSA partition.
But my problem is not SIM lock, it's "no SIM" at all, as I already said, if it was a Sim lock issue, I would have the "insert unlock code" dialog at logon.
- For reference : I've found the sources for CSPSA Android manager and desktop tools at : download.meego.com/live/home:/imppa/Trunk/src/[/url] (it's from the Meego project)
I think it would enable to read/write from/to CSPSA partition properly (not peeking/poking blindly).
- For now, I'm trying to analyse "adb logcat -b radio", but lots off errors seem to but "normal", I can hardly identify which ones are relevant.
Anybody reading radio logcat fluently ?
Guys, could any of you backup the 3 following partitions of their I9070P and post them somewhere to me so that I can try to restore them on my device to see if it sorts out my problems ?
The full tuto is here : http://forum.xda-developers.com/show....php?t=2145464

Hi Zakaria !
thanks for your answer.
This solution works if you have flashed a "I9070" ROM on a "I9070P". But I never did that, I have always flashed "P" ROMs.
I have checked the MD5sum of the files in my "tee" folder, they are (as expected) the same as the ones into the .zip you are recommending me (I've checked the rights too : everything is OK).
Given what I see in the radio logs (logcat -b radio), the problem appears to be under the RIL layer: modem seems OK but it replies that the SIM is "absent" when queried. It could be a hardware problem to, but as it worked well before, I don't think so.
I would really like to overwrite my CSPSA, modemFS and EFS partitions from a working I9070P to see if it would solve the pb (I've made backups of mine in the current "non working" state).
I'm just expecting someone to dump and send them to me...
Have a nice day.

I've always flashed stock ROMs from SamMobile. There are dozens of them.
As explained in a my first post in this thread, I have tried to upgrade to JB (German (T-Mobile) I9070PXXLPJ) : this is when appeared the "no SIM" problem.
Then I went back to GB (tutorial posted in xda ref. given in my 1st post) and then applied stock ROM from my Carrier: stil no SIM. (SIM card is OK in any other phone, and tried at least 3 other SIM cards from my carrier, -my phone is still SIM locked to it: no SIM).
Even if I use a SIM card from another carrier, I don't get the "Enter unlock code" popup.
If I remove any of those SIM while phone is on, I don't get the "SIM removed: reboot" popup.
I have even flashed the latest nightly CM10.1 for the I9070P.
I can past radio logcats if anybody want to have a look at it...

loose imei, not detect sim card

Hello,
I'm french, excuse my langage...
I have 2 note 8, an N950F (single sim) and an N950FD (double sim). I specify immediately that the 2 have already worked and that I have only one sim (one being for me and the other as a gift for my wife lol)
- On the N950F, install via odin 3.14 of twrp 33.1.2, then hadesrom 12 then magisk 20.4 => everything is ok
- Purchase of the N950FD, hassle with installing twrp because I had to put my sim in it to change the time and have access to the usb options, in short, it works, then same as hades and magisk => everything is ok
I have well customized the N950FD, I made a full save (all partitions) with twrp and I said to myself I do a full install on the N950F ...
At the time I did not watch out ...
I calmly use the N950FD and then, I still hack the N950F, I install other custom roms to see, lineage 17, etc etc and all that I do it without sim, with the dex dock connected in ethernet, in me saying that when I'm done, my wife will just put her sim there ...
And then something bothers me, it's a small prohibition logo at the top left instead of the network. I tell myself that this is normal because I did not put a sim, so I take that of my N950FD and there bah it is not recognized ...
I do not panic, I tell myself that I made a false manipulation, I wipe, I reinstall hadesrom and same concern, I take another custom rom and same concern ... I redo a full install with twrp and same concern .. .
I take a stock rom (the last, then the first, always in 4 files either with the csc or with the home-csc), I flash with odin 3.14 and 3.13 and always the same problems, the rom remains blocked on the screen samsung, the first with "samsung note 8 powered by android". So I tried the last rom with 3.14 and 3.13 then the first and still the same problem, it does not start (I waited 5 minutes roughly) despite the wipes ...
Since I no longer have twrp, I reflash, it works, I tell myself that the custom was still installed and I reflash via twrp hades (I tried the stock rom file but it didn't work) and again same concern, the sim is not recognized ...
I try the flash of the hades kernel, it works but the sim is still not recognized ...
When I go to the phone * # 06 # I do not have imei, but a black screen, when I go to parameter / connection / sim card manager => black screen with the message "com-android-phone does not respond" ...
I looked a little on the net, but nothing conclusive, I specify that all my files come from XDA but that given my English I prefer to try to find an answer in French ...
I do not have a backup of the N950F it would have been too simple, I tried another sim than mine but ditto it is not recognized and before making a tablet I would like to try everything to recover it. ..
It would seem that flashing a stock rom solves the problem ... But as said above, my phone remains stuck on the samsung logo despite the wipes
I still tried other things like just flashing parts of a stock rom but I still have the same problem ...
I also tried the flash of a stock with the extra pit and the nand erase and distribution options ... and similar, no start ...
I even reinstalled twrp after a stock, save it, "mix" it with another backup I had (efs and modem from the stock and the rest of the custom) but then again, it doesn't work, such reboots well but still no network access and no recognized sim card ...
Finally, I looked at chimera tool, but no tutorial in French so no way to see how it works or if it will meet my need ... taking an exclusive samsung license on chimera does not cause me any concern IF it allows me to do other things than what I have already tried ...
I also looked at the prog to change the imei because there is nothing left, not even 0, no no, a black page just like when I go to the sim card settings, I have a black page. ..
I also flashed several custom roms from different countries but it didn't work ...
By cons I observed that I had the location for 2 sim, still inactive ...
How to put the note 8 in single sim and recover imei and then the network ???
there, I block ... if you have ideas I am taker, thank you all ...

And then something bothers me, it's a small prohibition logo at the top left instead of the network. I tell myself that this is normal because I did not put a sim, so I take that of my N950FD and there bah it is not recognized ...
I do not panic, I tell myself that I made a false manipulation, I wipe, I reinstall hadesrom and same concern, I take another custom rom and same concern ... I redo a full install with twrp and same concern .. .
I take a stock rom (the last, then the first, always in 4 files either with the csc or with the home-csc), I flash with odin 3.14 and 3.13 and always the same problems, the rom remains blocked on the screen samsung, the first with "samsung note 8 powered by android". So I tried the last rom with 3.14 and 3.13 then the first and still the same problem, it does not start (I waited 5 minutes roughly) despite the wipes ...
Since I no longer have twrp, I reflash, it works, I tell myself that the custom was still installed and I reflash via twrp hades (I tried the stock rom file but it didn't work) and again same concern, the sim is not recognized ...
I try the flash of the hades kernel, it works but the sim is still not recognized ...
When I go to the phone * # 06 # I do not have imei, but a black screen, when I go to parameter / connection / sim card manager => black screen with the message "com-android-phone does not respond" ...
I looked a little on the net, but nothing conclusive, I specify that all my files come from XDA but that given my English I prefer to try to find an answer in French ...
I do not have a backup of the N950F it would have been too simple, I tried another sim than mine but ditto it is not recognized and before making a tablet I would like to try everything to recover it. ..
It would seem that flashing a stock rom solves the problem ... But as said above, my phone remains stuck on the samsung logo despite the wipes
I still tried other things like just flashing parts of a stock rom but I still have the same problem ...
I also tried the flash of a stock with the extra pit and the nand erase and distribution options ... and similar, no start ...
I even reinstalled twrp after a stock, save it, "mix" it with another backup I had (efs and modem from the stock and the rest of the custom) but then again, it doesn't work, such reboots well but still no network access and no recognized sim card ...
Finally, I looked at chimera tool, but no tutorial in French so no way to see how it works or if it will meet my need ... taking an exclusive samsung license on chimera does not cause me any concern IF it allows me to do other things than what I have already tried ...
I also looked at the prog to change the imei because there is nothing left, not even 0, no no, a black page just like when I go to the sim card settings, I have a black page. ..
I also flashed several custom roms from different countries but it didn't work ...
By cons I observed that I had the location for 2 sim, still inactive ...
How to put the note 8 in single sim and recover imei and then the network ???
there, I block ... if you have ideas I am taker, thank you all ...

If you didn't take a backup of your /efs folder which is where all of the phones important information is stored such as your IMEI then you are screwed because you can't flash any other phones EFS FOLDER.. However if you have a backup efs folder, restore it.
the concern is that I do not have a backup of the efs file ...
is it possible to put an efs file of another note 8 n950f and where to find this file on the net?

MrMike has already answered this, you can't share or use any other EFS.
The fact you can flash a custom rom and it will boot tells me you don't have a hardware issue, try flashing stock again as this can sometimes fix the EFS file, it has done for me in the past and a few others users. Although I can't tell you why you get stuck after flashing stock, this is the best way for you to hopefully resolve your issue as you don't have a EFS backup.
Except by flashing a stock, is there a way to restore the n950f to factory condition?
because with odin, if I flash the last stock, it does not start even if I make the wipes and if I try an old stock, odin blocks ...
can the chimera program allow me to find an original n950f?

Not that I am aware of, I am only aware of restoring by flashing stock with Odin or by using Samsung smartswitch.
You can't flash older filmware than what is already on the phone, that is why Odin is blocking that, but when you flash the latest filmware does Odin give you the green pass?
I am not familiar with the Chimera program so can't speak on that.
Yes with odin I have the green pass, but then the note 8 does not start, it remains blocked on the logo, even if I do the wipe ...
I even tried to save right after with twrp and recover the efs but it does not work ...
If I find a broken Note 8 can I recover the efs file by saving it and then putting it on my own?

Thanks for your help, how to start it in stock rom?
I specify that it starts in custom rom ...
the first photo is before the installation of the stock rom with odin, the second is at the end of the installation (odin ok, pass in green), the third is after the restart which has not worked (blocking on samsung note 8)

Could you please explain to us all in here how you're going to fix his /efs folder when he never made a backup of it.. Where are you planning on getting him an /efs folder that held all of his phone's information when he accidentally deleted it?

By root device and download Root Explorer, browse to the efs folder the delete everything EXCEPT the 'FactoryApp' and 'prov_data' folders it should restore IMEI
