Hello have a small questiom, how can i backup my stock current rom without any modifications ? In case of warranty or in case i don`t like a custom rom i would like to have a backup to flash back to my device . Can i do a backup or current 2.3.3 KP5 without any root access ? Or i need to get root, install cwm and backup, and in case something goes wrong ... reinstall that backup, delete cwm somehow and un-root the device
My device is Samsung Galaxy Gio btw
If u want go back, u can flash stock rom via odin. There are versions from 2.2.1 to 2.3.5 all by samsung.

Install Odin on your computer and CWM on the phone.
Make a Nandroid backup on the phone, but also dd the images as explained in some other threads (while still in CWM), so you can flash that through Odin if Nandroid bugs for some reason.
No need for root to do all the above. (CWM has root from the start, even if your ROM doesn't.)
It would be a good idea to check your CSC files for relocking before doing your backup and either fixing them or at least writing your code inside the battery cover.
Backup stock rom
You can use the program adb to:
(google some about how to use and install adb)
Sow commands from adb to backup the rom (system)
# cat /dev/block/stl12 > /sdcard/factoryfs.rfs
ore:
#dd if=/dev/stl12 of=/sdcard/system.img (img should be rfs but did not try that output my self)
backup the recovery:
#dd if=/dev/bml9 of=/sdcard/recovery.img
backup boot image(kernel)
#dd if=/dev/bml8 of=/sdcard/boot.img (probably will have same size ash the recovery image)
You can do a nandroid backup for most easy use this app can backup/restore any nice rom that you tryed very fast. Very save program to use. It comes with ClockworkMod recovery.
Some nice partition info is here:

If I have a stock rooted gs3 currently running ICS and stock recovery, can I just download goo manager or ROM manager and use that app to install the custom recovery?
Or if I'm on stock recovery is Odin the only way to install a custom recovery?
Thanks.

you are rooted.... forget everything you know about installing recoveries and follow this instruction here:
download the clockworkmod, or any recovery you want... download it straight from it's source site, so like clockworkmod.com, wherever... you are looking for the .img file of the recovery, not the .tar....
let's assume it is named "cwm.img" ... with me so far? put that file on your sdcard of your device, not the external sd card.... and put don't put it in any folders or anything, just download it, put it on your sd card... ready? here comes the easy part
download this app... https://play.google.com/store/apps/...251bGwsMSwxLDMsImphY2twYWwuYW5kcm9pZHRlcm0iXQ..
open the app, and type these commands for successssss (after each 1 of these command lines, you must hit enter)
su (it will ask for root permission, grant it, your "$" icon will change to "#")
dd if=/sdcard/cwm.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery (you should see an output)
reboot recovery
you are now in your new recovery.
This is way too complicated. Try this --> http://forum.xda-developers.com/showthread.php?t=1999922

Maybe you could fix this by using TWRP terminal commands, and enter the following:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc

Reboot.
Good luck
Thank you for your reply!
tried to do it but after
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota i got error :
can't open /dev/block/platform/msm_sdcc.1/by-name/fota no such file or directory
any ideas?
Checked in file manager - under /dev/block/platform i have only /f9824900.sdhci and not /msm_sdcc.1 . Also under mount - system partition is not checked, when I check it and reboot it is still get unchecked. Any advise?

Copy Stock Rom (older release is better)to the phone's root, then Wipe Dalvik/Cache. Return to Stock recovery and try to flash it, maybe it will fix the boot issue.

Already tried 13s official. Also tried to restore from system backup... still twrp bootloops...
Hi all,
First of all be carefull, Nobody will be responsible for bricking your device but yourself.
I compiled twrp 3.0 for blu advance 4.0 l2 (A030U) https://drive.google.com/open?id=0Bw48RaTkRMm_eTRXVk84aWJTUjA here the sources https://github.com/contrerasojuanc/device_blu_advance_l2_A030U, thanks to @Dees_Troy and its guide on https://forum.xda-developers.com/showthread.php?t=1943625. So, in order to install it on this device, we will need to unlock bootloader (Factory reset needed), and flash TWRP recovery on recovery partition.
Settings -> About device -> Compilation number click multiple times to get new developer options menu.
Enable Unlock OEM.
On terminal:
Code:
adb reboot bootloader
On terminal:
Code:
fastboot oem unlock
On terminal:
Code:
fastboot flash recovery twrp_a030u.img
On terminal:
Code:
fastboot reboot
(Immediately press and hold Volumen + on device until custome recovery shows up.)
In order to achieve root on this device, we need to install from TWRP a Supersu system-mode, available thanks to @mauam, it can be get at https://forum.xda-developers.com/apps/supersu/v2-64-2-66-supersu-mode-t3286120 (I used SR3-SuperSU-v2.79-SYSTEMMODE.zip).
Note that maybe /system need to be mounted as writeable, so first mount System and then, on TRWP's terminal:
Code:
/system/bin/mount -o remount,rw /system
Hope, it can be useful somehow. Any questions, please let me know.
I did everything right but I can not get root
Could you give more detail on how you installed supersu in system mode? I used the command mount -o remount,rw /system (replacing /system with the actual system folder path I found using the mount command in twrp temrinal) BUT discovered system remained read-only and everywhere I searched says you need to have root access to mount it as re-writeable.
I installed the zip you used anyways but am now stuck at the BLU logo screen. What should I do now?

The command I used for get writable /system was
Code:
/system/bin/mount -o remount,rw /system
exactly that one, remember that if you are in TWRP you have root access in recovery partition, so /system can be set as writeable from there. Probably you need to flash recovery and system partition again. I have those partitions from my stock device, let me know if want to give it a try.
Did you type any commands before that? I get the error "sh: /system/bin/mount: not found".
It would be great if you could link the stock partitions.

No command before, this is what I did:
1. In TWRP tap Mount menu, then check "Mount system partition read-only" then check "System", then middle bottom button (Home). (So now we have /system partition mount but as RO)
2. Tap Advance menu, Terminal and type
Code:
/system/bin/mount -o remount,rw /system
3. Now if all goes alright, we should have /system writeable.
4. With /system writeable, tap on Install menu, select the Supersu file (Only this worked for me SR3-SuperSU-v2.79-SYSTEMMODE.zip).
5. Deviced rooted.
Ok, I'll try to upload the partitions tonight, while you could search the rom in web.

Yes, what you describe is exactly what I did on a previously stock device, but with the same issue on terminal I posted before. After ignoring that, and sideloading the supersu .zip you used, the device gets stuck on the second BLU logo screen on boot, no hope getting back to system. Hopefully it works the second time around with stock partitions...

Hi, the only way I know would be to flash stock partitions of that device. If you manage to find them in the web, I could tell you how to flash it.

thank you for your attention, I'm already trying your recommend, but no success yet. I have the stock, sp-flash and drivers (for win). I think it is any problem with drivers or sp-flash (v5.1712)...
Not working
Hi, I have a BLU Advance 4.0 L2 (A030U) and the TWRP doesn't work in my phone, it boots but the touchscreen isn't working, any suggestion?
UPDATE: I was booting twrp from fastboot because I wasn't able to flash it like is explained here, I think that is why my touchscreen wasn't working, anyways I managed to flash it through SP Flash Tools and It worked but now the root doesn't work, it softbrick the phone everytime I try, I'm able to mount system and all that stuff, everything is successfull but the phone does not boot.
Thank you
.It successfully helped root my Advance 4.0 L 2 A030L in yesterday.
I bad English.
I tried flash superuser.zip(superuser.phh.me_2016-09-23), Magisk-v14.0.zip, SR3-SuperSU-v2.79-SYSTEMMODE.zip, they could root my A030L(stock-V05_GENERIC）
if not fastboot reboot"(Immediately press and hold Volumen + on device until custome recovery shows up.)" , devices will replace your custom recovery automatically during first boot.
Other unimportant: Recovery in A030L also need remount / system, there is not read SDcard (update.zip can be imported in TWRP or OS to internal storage),can't backup userdate.can't input password to read userdate after Encrypted.

Ver-V05 can root both ok. Ver-V12 look like something wrong in boot.img,it can only root by Magisk. Maybe you should flash boot.img from ver-V05 if you want use V12.
i have a030u v12 rom. v5generic not work, after install result crash bootlogo loop same make option format... recovery not work! same press up button! after all process not enter in twrp. i test magisk not work customize boot.img flash to sp flash result crash boot! mtk droid not detect my phone too please help me.... very hard root this device!
