How to make a full backup before installing roms?

Hello,
I would like to create a full stock backup, I do not care for applications or settings, the only thing I want is full non-rooter, current Gingerbread with ability to install possible upcoming OTA updates.
The reason for this is simple, I want to try out different ICS roms just for fun and then go back to original, HTC Sense 2.1 powered rom.
The question is: How do I do that? I know I can handle rooting the device and installing various things but how do I get back?
Thanks!
PS A link with instructions on how to do that would be nice, I tried searching the forums and Google but nothing legit came out.

If you have already rooted your phone and installed a recovery such as ClockworkMod or 4EXT, reboot into recovery and go to the "Backup" menu and make a full backup.
In the event of problems, you can do a full wipe or factory reset, and then go to the same backup/restore menu to restore your backup from the SD card.

But if the phone is Gingerbread (it is) I have to downgrade first, correct? To Froyo 2.2. So Basically that leaves me with a copy of 2.2 while my phone came with Gingerbread in the first place.
It basically shows that I've changed (downgraded) the software, doesn't it?

If you have ALREADY rooted it, then there is no need to be downgrading back to an exploitable firmware when you've already exploited the phone. If all you're doing is installing a custom rom on an already rooted/unlocked phone then you need only flash the roms via recovery.
You would only have to downgrade the firmware if you for some reason decided to flash the original stock firmware, hboot, etc onto the phone.
But that's least as far as the backups go.
In terms of how to get the phone back to non-root/locked state there's a sticky/wiki for that, though I would find it to be a pain in the butt to have the phone rooted and unlocked and then have to go thru the process of locking it back up only to possibly risk bricking it. The more times you mess with the firmware/radio/hboot the more likely you are to brick it.

Just to make it all clear my phone is kinda new, was never rooted, that's why I'm asking. I still can't believe that HTC doesn't have an app like Xperia has, SEUS to be exact, you can fix any phone with one click. By saying fix I mean install the latest, official rom.
That's too bad there is no other way to root Desire Z.

If never rooted there's not much of a way to make a full backup first (since most backup tools like Titanium Backup requires root).

Well there is the HTCDev unlocker from HTC themselves, but you actually have better luck following something like cyanogenmod's wiki entry.
Something like this works quite well : http://wiki.cyanogenmod.com/wiki/HTC_Vision
You just need to make sure to triple-check all the numbers and messages, someone accidentally skipping 2 or 3 steps multiple times is just asking for problems.
But once rooted (like for my G2 I followed the cyanogenmod steps, and then went another step by upgrading my radio to the latest, I just went with a different rom after being rooted) it's usually best to keep it that way even if you decide to just flash the stock rom (i.e.: still rooted and unlocked, but simply using the original software they provide you, which can be rooted simply by having the su binary and superuser app).
The voiding of warranty usually applies to software, i.e.: you bricked the phone as a result of flashing the wrong hboot. Where as if the screen or eMMC dies, it's a hardware failure and shouldn't be voided simply because the phone was rooted (unless of course they determined you fried your CPU by running the phone at 1.9Ghz constantly).

You could just download a full version of the G2 gingerbread rom from shipped-roms.com and flash that if you ever want/need to go back to stock gingerbread.

[Q] BL locked on Xperia ZL. 4.4.4 - 0.292 - What are my options?

Hello,
I have a Xperia ZL C6506 with a locked bootloader. I would like to unlock it, or at least root the phone.
Bootloader unlock allowed: No
Android 4.4.4
Kernel version: 3.4.0-perfg1bb39c2
Build Number: 10.5.1A.0.292
Country: Canada
Flashtool will not root the phone, even trying Towelroot V3.
Seems like every answer I find on XDA says something about my phone is always stopping me. Either 4.4.4 is a problem, or BL locked, or 0.292, I can't root... What am I missing?
Do I have to flash a new kernel or rom? Is it even safe to flash anything, even if it is stock, on a phone with a locked bootloader? I do not want to brick.
Thanks in advance for your help!

I found this forum: http://forum.xda-developers.com/xperia-zl/help/rooting-xperia-zl-t2994781
But,
I read this: http://forum.xda-developers.com/xperia-z1/development/newroot-z1-t2807092 it says: "Newroot work with all kitkat firmwares but doesn't work with latest kitkat *after 108) .133, .157... firmware or with old JB firmwares!!!"
This is the only thing that I have found that I have not tried, but I am hesitant to try and flash an old kernel on a phone with a locked bootloader. Is it safe to flash anything on a locked bootloader?

Yes, it is safe, as long as you know what you are doing. Put it this way: flashing the downgraded kernel will not screw you up, but doing things the wrong way might.
1. Download this. It's NOT a flashable zip! Just unzip it, and use FTF files to flash the appropriate kernels.
2. Read my post that you linked. It gives you all the steps of the process. Installing recovery is optional, but highly recommended (very useful). Use the kernels you downloaded from my link above.
That's it! A couple of notes...
- I am assuming you know how to use the FlashTool. Not the original one from Sony, but the the one by Androxide. Make sure you are familiar with it before flashing!
- Newroot DOES work with .230 kernel. I have done it many times while playing with different ROM versions, works perfectly. Make sure you enable USB debugging, and watch your phone for prompts to grant access. Your phone should reboot after successful rooting. If for some reason it doesn't work, just try again.
- When you flash .230 kernel, you may have some weird issues with your phone. You will lose WiFi. Your phone may start vibrating for no reason (mine did). Maybe something else, I dunno... Don't worry, it's only temporary. Everything will get back to normal once you flash .292 kernel after rooting. Again, tried and proven fully working many times.
- If you decide to upgrade to LP afterwards, this will also be your procedure to recover, if you screw something up in the process (been there, done that). Just flash your .292 stock ROM, then repeat the rooting process, then start with LP over again.
Happy rooting!

Thanks so much. It is crystal clear now. Always good to get some advice from someone who has done it before on the same phone.

Trying to flash and I got this error (attached pic)
I am running the newest flashtool. I didn't have any problem with the older flashtool in the past when I used to flash my older phones. Also, the older one installed completely in one folder, this one installs in 2 folders, one in C: and the other in C:/users/Me for some reason.
I installed the V1.5 driver package. Not sure what else is wrong. I unzipped the zip file, put the kernel.only.ftf into the firmwares folder, I clicked flash, selected the .ftf file and connected the phone in flashmode. No dice.

Ok, tried it again, this time it didn't get a red error, I got a different one, and my build number is still 10.5.1.A.0292...
Installed recoveries.
Pic is attached.

Okay!
So, after the first flash, the build number didn't change, but the kernel was applied. I just tried using newroot and it worked, superuser is there. Just like you said, the wifi stopped working with the new kernel. I flashed the 0.292 kernel and the wifi came back, and the phone is still rooted.
Thanks for you help kt-Froggy!

Flashing branded software

Hi guys, I've been reading a lot of different threads, but have gotten myself confused. Its been a long time since I done flashing of software, and things are completely changed since then.
Anyway,I currently have the z5 premium which was purchased in o2, however I have now moved to ee and would like the WiFi calling feature. My handset hasn't been rooted or nor can the bootloader be unlocked. Can I still download stock ee firmware and install it without any problems.

I find most branded firmware to be buggy in some way.
there is a tutorial for backing up your TA partition ( the bit that keeps your DRM keys)
https://forum.xda-developers.com/crossdevice-dev/sony/iovyroot-temp-root-tool-t3349597
and a tutorial for unlocking your bootloader, and compiling a patched Stock Kernel. from there, you will be able to install any of our great Custom roms.
https://forum.xda-developers.com/xp...oot-automatic-repack-stock-kernel-dm-t3301605
If you decide instead to keep your phone locked. you should still be able to flash a stock rom using the FTF and the flash tool. you should still backup all your data, photo's documents etc before doing anything at all with your phone.
and always try to start any new flash completely clean. and build up from there, instead of trying to retain your data, or restoring your apps.
If you want more help with backing up and rooting / unlocking your bootloader just ask. but post the exact model version of your device. as the z5p has 4 different models.

Thanks for the reply Patrick, I got all sorted. Unfortunately the bootloader can't be unlocked on my handset, so can't use custom ROMS. However, I was able to use Flashtool and XperiFirm to download EE's branded firmware, and now I have the WiFi calling feature. Thanks for your help.

XZ1 Compact - Pie to Oreo downgrade

Hi all,
I'm in need of some guidance with regards to a downgrade that I'd like to perform.
About 1 week ago the phone updated itself OTA. I don't remember which version was last before this update .. but what I remember is that the download was quite consistent (over 1G) and then the update took a while. Everything went by without any errors, but at the end I got Android Pie ... and I don't like it.
Reading through the forums I found that flashing a Xperia is doable .. with the right care and tools. So I started to get acquainted with newflasher and Xperifirm - but for now not connecting the phone and / or trying anything and here are the questions for anyone who might guide me a bit:
1. the phone is warranty (about 4-5 months old in fact). I believe the latest firmware that it was running with Oreo was 47.1.A.16.20-R6B. Reference = h**ps://xpericheck.com/cda/1310-4373. I don't see that version in Xperifirm => how can I get access to it for re-flashing?
2. as far as I read, I don't need to root it or unlock the boot loader. Just flashing would be enough to go back one firmware "edition".
3. backing up user data does not interest me so much. I have a list of all apps that are currently installed and within a few hours of tinkering I could get them all re-installed.
4. Would the process of downgrading be visible afterwards? - i.e. warranty would be "bye-bye", right?
.. any other comment / note / reference or observation is highly appreciated.
Best wishes!

Hello,
Thanks for the quick reply.
For sure it confirms my understanding of the process.
Would there by any chance to find my Oreo 8 previous firmware (47.1.A.16.20) but for my "Customized DE" version?
It intrigued me that Xperifirm has just the latest one.

I don't think there will be any difference between customised DE and customised UK, there will be VoLTE and fingerprint enabled.
If you have to start asking other xda users for historical firmware then you can't guarantee its validity.
All the firmwares on Xperiafirm are direct from Sony servers.

I secured the Oreo firmware (customized UK) and the Pie firmware (customized DE) .. using xperifirm. I downloaded Pie just to have the current release that's running on the phone nearby, in case any of my attempts go bad and I'd need to restore it.
By chance, I have for about 2 weeks the possibility to have a non-branded original "Customized UK" XZ1c. As far as I've seen, there 1 app only that's different compared with my original customized DE. I might flash this one to Oreo and back to Pie ... just to learn the process ... and only afterwards to get to work on mine.
I also took my time to look around the web before jumping into flashing.
There are topics which I don't quite grasp yet .. like DRM .. or attest keys.
The thing is that I don't want to break anything in doing this downgrade to Oreo. I don't need to root it, to unlock the boot loader, to break any X-Reality or other functionality. I'm truly amazed by the battery life, btw: I get 3 1/2 days plus with Stamina activated non-stop. The phone is very snappy even with Stamina ... and that's another issue: by downgrading, I wouldn't like to ruin anything of the battery management internal apps / features.
Another thing is this: i don't intend to preserve any data. Whatever I have as apps, currently, will be backed-up and re-installed from scratch + restore of personal data.
I'm now at the point of going through:
1. flashing with flash tool + xperifirm
OR
2. flashing with newflasher.
Basically, I'm trying to understand what the differences (risks) are and what's the safest to use.
Any advice from the XDA community is welcome on this one.
Best wishes,

@metalik download the firmware with xperifirm and from settings select to decrypt/decompress (don't remember how it is). Then delete all .ta files from the folder and persist*.sin (to avoid losing android attest keys and flash with newflasher.
Flashtool has some problems with newer phone models so it's not recommended for xz1c.

the right question would be, how to get the latest security patches but staying with oreo?

gentlemen,
your input is highly appreciated.
aside from the persist*.sin and all .ta files .. should I take care of anything else?
P.S. I followed this tutorial (link) and it clearly indicates that warranty would not be voided if I would attempt such a re-flashing. Is it true?
P.S. the last question in the thread remains valid: how to apply the upcoming patches on top of Oreo? .. can those be obtained and flashed in a similar way? ... I doubt it would be a good approach because Sony is supposed to take the Google patches and make sure they integrate properly in their Android customization ...

First take a screenshot of your current keystore status by typing this in the dialler *#*#7378423#*#*, then go to Service tests or Service info -> Security
I used newflasher since it's the last updated software for flashing.
Extract your ftf if required, put only the required files to downgrade in newflasher's folder. For me I only used kernel, system, userdata and cache.
Boot to flash mode, flash using newflasher, reboot and done! Make sure your keystore is intact by comparing the status of all keys with your screenshot.
I've used this method to downgrade temporarily, get temp root, backup my TA partition and then go back to current firmware. All keys intact.

I would flash everything else but the .ta and persist*.sin to ensure it works as intended with all files from the firmware you're using. Of course that resets all your userdata, but I guess a downgrade would require that anyway.
Warranty should be just fine - you're still just using official Sony firmware without any modifications to the device or system.
I don't think it will be possible to stay in official Oreo fw with locked bootloader and get recent security patches.
Sony will most probably implement the new patches only into the latest fw version - and that's Pie.
And if someone would make a custom rom with the latest patches on Oreo, you won't be able to install it with a locked bootloader.

Hello again,
what's the impact of flashing persist*.sin ... I believe that's connected with the attest keys, right?
Later edit: I downgraded from Customized DE Pie to Customized UK Oreo. I used newflasher, deleted all *.ta from the root & boot folder ... but by mistake I forgot about the one small persist*.sin file.
Long story short: yes, leaving persist*.sin file in the folder and flashing with newflasher destroyed the Attest keys (I get them as NOT provisioned).
The phone seems to work without problems nevertheless. I re-flashed to an older Customized DE Pie and got the last valid OTA update. Going back to Customized UK Oreo did remove everything from the Service Tests > Security (it showed "none"). But on that the Xperia Companion did the trick (software repair). So it's back on the initial Customized UK Oreo - just attest key shows NOT provisioned ... so
Lessons learned: /*.ta + /persist*.sin + /boot/*.ta must be removed before flashing with newflasher.

Great! I have also been searching desperately for a G8441 47.1.A.16.20 firmware. The country doesn't matter.
If either of you are able to send a zip, I would love to host it on my drive for anyone else who comes looking.

@cynthi4 Customized NOBA (nordic/baltic) latest Oreo: http://aeitis.org/xz1c/
It's downloaded and decrypted via xperifirm and zipped.
I'll keep it there for a while, but might remove soon.

Hello, I just got a xz1c and I'm on 47.1.a.2.281. I haven't updated because of reported battery drain issues. Should I stick with this? Do you recommend pie at all? If not, what's the most stable build you'd recommend?

Unless you have any specific issues with Oreo or see some advantage with upgrading to Pie, I wouldn't. I am not a big fan of Pie and went through this downgrade to 47.1.A.16.20 to avoid it. If you're interested in custom ROMs, I am running LineageOS 15.1 on my xz1c and it's been great!

That's strange. Being still happy with my locked device, I've always regretted switching to pie so today I actually did the whole process to restore Oreo: downloaded the latest Costumized NOBA oreo the user few posts above linked, deleted *persist.sin and every *.ta files in the folder (even the one inside boot folder), run newflasher and then reboot. Too bad I found stock camera broken
I re-checked multiple times searching for those *.ta files to be sure to avoid this issue, but that's it: I got Oreo but now I have lost stock camera and who knows what else.
Does it mean I've lost those functionality forever? Is there any way to restore stock camera? Happy to see this thread still active

Backing up everything or restoring partitions to original state

Hi I've always tinkered with my phones but with the One Plus 7t Pro nothing ever gave me a reason to root until now (quick step) but so far there has always been a reliable method to go back to full stock whether it's fastboot on nexus device with the official google images or Odin on Samsung devices. So I've been documenting myself and trying to understand the different partitions. My understanding is that one plus on it's website only offers system images so if I ever came to loose my other partitions what would I be able to do ? I've seen a tutorial with EDL mode but where does the firmware come from ? MSM tools only restore boot.img and system.img right ?
Also how could I go about backing up my persist partition.
So basically before I root I wanna be sure that I can go back to partitioning my phone exactly to how it was before with official firmware or if there is no official one, backing up mine before rooting.
Any clarification would be appreciated !
Thanks,
