[Q] How to backup after htcdev.com UNLOCKED SHIP S-ON - HTC Desire S

Ultimately I wish to install custom ROMs but first I would like to make sure I understand what I'm doing.
I would like to do an Nandroid backup before changing any partition, however after the official unlock my device still doesn't meet the requirements for Nandroid - the recovery I've got doesn't have adbd and busybox - and I cannot fastboot flash a new recovery unless the device is ENG S-OFF. Neither can I boot from a custom image in fastboot, it just says "FAILED (remote: not allowed)". So what are my options if I want to backup of my boot, recovery and system partitions, without having to overwrite them first.
Your comments are much appreciated.

After using HTC unlock my device was wiped clean. Didn't know before everything would be gone. Is there a way to backup before?

[Q] HBoot 2.00.0002, unlocked, S-ON and recovery destroyed !

Hello guys,
My recovery doesn't work anymore : I get stuck on the HTC logo.
Apart from that, my phone is fine : the bootloader works and I can boot my phone in normal mode.
Me being stupid, I unlocked my phone with HTCDev and though that was enough to get the phone S-OFF.
So I flash a 4ext recovery image without doing any backup (another rookie mistake). And since, I cannot launch the recovery.
The hboot is 2.00.0002, and I still have the original unrooted 3.0 Sense ROM.
I don't want to go on tinkering with my phone (ie rooting, S-OFF and install a custom rom) until I fixed the recovery.
So I have the following questions :
1) what I can do to restore/fix my recovery ?
2) do you have a backup recovery image for a French Orange HTC Desire S ?
3) what procedure should I follow to backup my phone NOW (boot, recovery, data, rom, etc...) ?
Thanks for your help,
Deckard
Flash in fastboot recovery.img
download the 4EXTRecovery_v2.1.0_saga.zip package here http://forum.xda-developers.com/showthread.php?t=1130004
rename it to PG88IMG.zip
put that file on the root of your sd card
start you phone in bootloader (hboot not fastboot)
the bootloader will ask you if you want to install recovery.img
confrim
reboot
rename the file again into something else or delete it (cause bootloader will always try to flash if a PG88IMG.zip file is on your sd card every time you boot into it)
If you are rooted, the easiest solution to get a working recovery, one that doesn't involve fastboot, hboot, multiple restarts, adb etc, is to simply download the recovery updater app (free) from 4ext.net and use the app to download and flash your new recovery (4EXT Recovery) without any reboots or jumping through hoops!!
Hope you get what you want... you have all the possible solutions now (see posts above)

The OP stated that he has HBOOT 2.00.0002 and stock, unrooted 2.3.5/Sense 3.0 ROM, so your solution will not work for him.
He will need to flash a recovery.img using fastboot.
Thanks for your answer, korenisko
The truth is that I nicked my recovery using that particular command
(fastboot flash recovery recovery.img).
I tried to flash 4ext 1.0.0.3b9.
So, I'm a little wary of it right now.
I didn't understand why it failed. Is it because my phone wasn't S-OFF ?
Because I weren't root (as far as I know, it shouldn't matter) ?
Because the downloaded file was corrupted (the zip seemed valid, though) ?
Because I unlocked my phone through htcdev ?
Do you have any idea ?
Anyway, for the time being, I am a little puzzled. And uncomfortable.
I don't want to messed up again.
I guess, I don't risk anything trying to flash another recovery....
Maybe the stable version 4ext...
Thanks for your suggestion !
Don't I need my phone to be S-OFF before I can do what you are suggesting ?

[Q] Rooted etc., then flashed RUU, now unable to install recovery or run su!

This is my saga thus far:
1. Followed the guide ... more or less. For some reason it wouldn't install CWM as PG58IMG.zip via fastboot automatically (it detected it, said it was parsing, then just went back to the menu), but I was able to install the img using fastboot flash recovery recovery.img (where recovery.img was the CWM img). Anyway, everything worked properly, I had the SuperUser app, I could use 'su' in the terminal, etc.
2. I flashed 4EXT Recovery. Also worked perfectly.
3. Played around a bit, whatever.
4. Did a backup via 4EXT.
5. I bought this phone used from eBay, so I wanted to ensure there was nothing malicious hiding in the system partition. So I used RUU_Pyramid_BM_1.45.666.5_Radio_10.56.9035.00U_10.14.9035.01_M_release_220007_signed.exe, which is precisely what was installed before. That was successful too.
6. Then, when I set things up, Google started "recovering" my apps, i.e., downloading a bunch of apps I had on my old phone. I was not impressed by this. So I went to Settings > Storage > Factory Reset.
7. Then I reinstalled the RUU. I'm not sure if it was necessary or not.
Now I seem to be stuck. I'm not bricked -- I can do everything an unrooted user can do. But I'm pretty sure I'm NOT rooted. The Superuser app's gone, and when I type su in the terminal, it says "permission denied" (which is interesting, shouldn't it say it can't find it at all?). In the bootloader/fastboot, it says S-OFF. It also says **LOCKED** above that. I'm not sure whether that refers to system access (i.e., root permissions) or the SIM (phone was unlocked before). But the strangest part is with ADB. When the phone is on in normal mode, I can install apps, push/pull, etc. But within the bootloader, adb's not recognizing the device at all! What's particularly weird is that the fastboot command IS recognizing it! And when I do fastboot getvar cid, it's still 11111111. But it won't let me flash a custom recovery.
So, I seem to be stuck. It seems to be S-OFF, but I can't flash a recovery. I can't even restore my backup, since I need the custom recovery to do that!
Any ideas as to what I can do to re-root my phone?
EDIT: I'm watching a YouTube vid of the phone being S-OFF'd. When he started off, his bootloader screen looked identical to mine except it said S-ON. When he finished, it said S-OFF, but it also said **Revolutionary** instead of **LOCKED**. OK, so, if I try running Revolutionary again, will it fix things, or will it do nothing or even brick my phone? Will I have to do the S-ON procedure and then start anew?
You have s-off with a locked 1.27 hboot. That's ok, at least you have s-off so you have access. Don't worry about the "locked" bootloader! adb will not connect in bootloader. That is normal. You must use fastboot when in bootloader. As far as a recovery goes, you'll need a PG58IMG with the correct mid in order for it to flash. From bootloader:
Code:
fastboot getvar mid
You can use 7zip to extract the PG58IMG and notepad++ to view the android-info.txt. Make sure your mid is listed... If it's not listed then you can add it, pack it all back up, put on root of sd and flash through bootloader.
Once you have your recovery you will have to flash superuser to regain root access.
I had this exact issue the other day on a gingerbread RUU, to fix it I ran revolutionary even though I was s off already, then rebooted the phone, and flashed this recovery from bootloader

This is the only one I managed to get to work, others just said 'parsing' then did nothing

[Q] [Help] My HTC One S not booting on after rooting

Hi Everyone,
This is the first time I am playing with a mobile software.
I did the unlock bootloader as per the instructions given in htc website, and my phone status shows unlocked, but it is still S-ON.(Hboot 2.51)
I was planning to install a custom rom either CM11 or MIUI5.
After reading many threads in xda as well as in other sites, I tried to do a S-OFF to install a custom ROM.
I tried Rumrummer, Moonshine and firewater, but nothing has made my mobile as S-OFF.
I tried to restore back to the original stock rom, and followed the process in htconeforum(how-unbrick-restore-htc-one-s-stock-relocked)
So, I tried to do an oem lock and it got relocked.
Now, I tried to do an RUU, and it didn't work with data transfer error.
Only Hboot comes on my phone with the below details
***Tampered***
***Relocked***
My Phone doesn't start now; tried pushing lot of CWM and TRWM recoveries, it got stuck in sending recovery for long time, and i exit.
Can anyone please help me and let me know, how can i restore back to htc rom or go forward and install custom rom.
Thanks,
Deepak

Stuck in sending recovery/sending zip flash
Some how , I managed to push CWM recovery to my phone.
But when I select install from zip, it says "Error mounting SDCard".
I tried the fastboot oem lock using all in one tool kit and now it says Tampered, Relocked.
So, i am trying to run factory RUU exe , it stuck at sending recovery.
I tried to push the .zip factory RUU, and it says sending and stuck there.
Even I tried the adb sideload, it says data transfer failed.
Looks like all the data on the SD card(in my case internal storage) is gone during erase and I don't have any flash zips on the device and I am not able to send any flash zips to the device.
The drivers are installed correctly, and my HBoot 2.15 says fastboot usb when in bootloader, but when i type adb devices, it gives no device.
Can some one please help me in getting my phone back.
Thanks,
Deepak

I suggest you get the OTG USB cable. Load the ROM on a Flash USB and then use TWRP to install the ROM (Remember to mount the OTG in TWRP) Check Amazon, it only cost less than $3. I've never push the ROM to the phone. Saves a lot of time when you have multiple phones.

Booting TWRP Advice

HTCDreamOn said:
A word of advice: I strongly recommend temporarily booting any images (be it recoveries or kernels) you are about to flash to your device. This is simply a case of using the command "fastboot boot blahblah.img" whether blahblah.img is a recovery or kernel.

We know you can boot to TWRP vice flash to your device by using the command:
Code:
fastboot boot twrp.img
But how do you proceed from here? Are you required to use ADB commands at this point or can you unplug your USB cable and use TWRP as if it was installed, I.E. , back up current ROM, and install new zip.

Sorry if I wasn't clear. Yes you can unplug usb and use as normal, it just means twrp isn't flashed to the device so it won't be there when you reboot.
I just recommend this step because I'm paranoid. Once you've confirmed the image works you should reboot to bootloader and fastboot flash the image, then you'll be able to boot into twrp whenever you want.

This is a good step to do, and if the device supports it it should be used... for example the Moto G (if unlocked) fully supports fastboot boot commands, devices like the HTC One M7 do NOT support this anymore...
To the OP, what is really happening here is that TWRP or the boot.img (kernel) is being loaded from USB into RAM and executed normally, instead of the standard /boot partition which is skipped when executing fastboot boot. TWRP (and recovery in general) is really just a specialized micro-sized android distribution and when started via fastboot boot is executed as if it was the boot image. Once the image is transferred into RAM, the boot continues normally per the instructions of TWRP or the boot image, and no further action via USB is required. USB is just the medium to load the image into RAM and nothing more.
fastboot boot - used to manually load a boot image (or recovery) and execute from RAM, it is not flashed to the device, on the next reboot it will return to it's previous state
fastboot flash boot/recovery - used to actually flash the boot image or recovery image to the it's appropriate partition on the device, it does not execute it. On a reboot or factory default this information will stay in the device.

Thanks. So it seems there is no reason to ever flash TWRP unless you don't want the PC dependence to use the TWRP tool.

Well, sort of... but the point is once you flash anything via twrp, you are no longer stock, so why not flash twrp to make it easier to flash other things?
The smartest thing would be to unlock, boot TWRP, make a nandroid backup before you do anything at all, then flash TWRP and do your thing...

I understand what you are saying. The only flash I planned on was SuperSU. I thought when a system upgrade is available, I could simply use SU to unroot and be ready for the update. Would this work?
If I followed your recommendation, could I feasibly, flash TWRP, then when an upgrade is ready, flash nandroid backup (which I assume removes TWRP) then accept system update, then re-flash TWRP. I could restore apps by using TB. Does this make sense? Or does TWRP remain in place after flashing nandroid backup?

TWRP remains in place after restoring a nandroid (I think, I haven't installed on my Moto G, but in most devices it doesn't backup/restore recovery), but you can easily restore the original recovery via fastboot.

Hey thanks for helping to answer this, your explanation was much better I thought it had something to do with loading into RAM but wasn't sure. I didn't know some devices don't allow fastboot boot commands though, I've always relied on them. Part of the reason I'm avoiding htc now.
@purplepizza I agree with everything acejavelin has said: essentially you really do want to make sure your have twrp flashed.
To answer your nandroid question: It basically just takes an image of the partitions you choose, usually /system, /data, and /boot (where kernel stuff is) which is the least you need to boot back with all your data. It doesn't backup recovery and when you restore it doesn't write anything to recovery, so yes twrp will still be in place. In general you should only ever flash stuff to the recovery partition whilst in fastboot mode (i.e. using fastboot flash recovery recovery.img), I know on some devices you can flash recoveries as zip files in the recovery itself but you shouldn't.
I've seen quite a few people querying about the 6.0 OTA: in short, I wouldn't worry about it because once they start rolling out, people always catch the OTA and post here on xda. You can flash that and it'll return you to stock 6.0 anyway, at which point you can reroot and everything if you want.

One more question, when making the first nandroid backup. do you just back up system and data or do you include boot as well?

So what is boot? I know I am kind of going back to my previous question, but if I restore boot, is that the boot loader? I would assume this would not commonly need restored?
And I now assume the bootloader is completely independent from recovery.

It is not the bootloader... It is the /boot partition of the phone, basically the kernel and RAM disk. If you screw things up and need to restore, you typically want to restore /boot, /system, and /data, and occasionally /cache (if you want to restore to save time and get an exact duplicate of the previous image, otherwise many people skip /cache and let it rebuild on the first boot which takes 10-15 minutes extra).

So I am following your advice. I booted to TWRP, made Nandroid backup.
Rebooted and flashed TWRP, see below:
Code:
sudo fastboot flash recovery twrp.img
target reported max download size of 268435456 bytes
sending 'recovery' (7772 KB)...
OKAY [ 10.635s]
writing 'recovery'...
OKAY [ 0.141s]
finished. total time: 10.776s
All seems OK.
Scrolled to recovery, selected recovery. TWRP was there. I then powered down.
After that I held power and volume down, system boots to dead Android with message “No command” Held power then volume up, I see stock boot loader. Is TWRP flashed somewhere or is it gone? So what did I do wrong.

Any recommendations how to proceed?
I also need help with my soft bricked moto g3
Moto g3 (xt 1550, Indian dual sim 16 gb version)
I officially upgraded to 6.0.0 via ota and my objective was to root my phone and use xposed modules. I am not interested in any other custom rom (I'd rather keep stock rom just for moto display and ota upgrades) or custom recovery like twrp(I'm afraid it may cause ota upgrades to fail).
I used the method described here in the question- http://android.stackexchange.com/qu...rsu-using-play-store-versus-a-custom-recovery
So I first successfully unlocked my bootloader using the official motorola method.
I then proceeded to use google's backup settings to re-install all the apps that were uninstalled due to unlocking the bootloader. I also put supersu.zip version 2.46 on internal sd card.
I then proceeded to (without rebooting) enter fastboot where i used minimal adb to temporarily boot into twrp version2.8.7 r5 (link - http://forum.xda-developers.com/2015-moto-g/orig-development/twrp-twrp-moto-g-2015-t3170537 ).
Once in twrp, I located and flashed the supersu.zip. It flashed successfully. I procceded to clear dalvik cache and then after clearing cache I tried to reboot my phone using twrp.
However, it did not go beyond the "Warning - Bootloader Unlocked" screen that you get on unlocking a motorola bootloader. I left it for over 10 minutes (usb was still plugged in, I had >80% battery) but it did not proceed.
Long -pressing the power button causes the phone to vibrate and again attempt to boot, stuck at the same initial screen. Adb quite understandably does not work here.
I can press vol down+power and enter fastboot , where adb works fine.
I can enter stock recovery from the fastboot sceen too.
Using adb in fastboot, I am able to boot twrp . In fact, I tried to re-install supersu.zip. I retried version 2.46 and then tried version 2.56. On all occcassions, it was able to successfully flash it, but gets hung on the initial boot screen.
USB Debugging is also enabled, and I have a backp of my sd card data.
I tried taking a backup of the system and apps in twrp (3 gb in total) and tried to reflash it, but it still hangs at the same screen.
Is there any way I can unbrick my device and- (in decreasing order of preference)
1. Keep my stock rom and recovery?
2. Keep stock rom with twrp? (It should not be a problem)
3. Custom rom with custom recovery - perhaps official cm. Least preferred as I want Moto Display and stock/vanilla android.
Also, is SELinux involved anywhere with my phone getting bricked? I also read that a custom kernel is required for rooting 6.0, which I don't have. Supersu Version 2.56 is said to prevent soft bricks if the kernel is incorrect (systemless root), yet even after flashing the newer one it is still bricked. Where am I going wrong? What should I do? Thanks in advance! :good:

Try the flash again? Sorry, but I don't really know help... if you are successfully rooted, perhaps try to flash TWRP image with Flashify? (select your file, don't let it auto-grab an image)

I have not rooted yet. I guess I can try by booting TWRP then flashing SuperSU.
Can you think of any reasons not to try fastboot again the re-flash TWRP?

Backup persist partition without unlocked bootloader?

I've read advice to backup persist partition before making any changes to the device but I can't seem to access that partition without root(?) or something like a custom recovery, both of which require unlocked bootloader (even if only to run the recovery and not flash it).
Is there any way to back up persist partition on a locked bootloader? Does it matter if I never set up my fingerprint?

try MSMtool readback function. google it pls
Although it does require bootloader unlock, I found it is possible to backup the persist partition without rooting and without installing anything by using TWRP:
* find a TWRP that is compatible with your phone
* fastboot boot <twrp.img>
Even though that's not a root tool, it makes partitions available such as boot, recovery and persist partitions for backup either via the "dd" command (in adb shell) or by "adb pull"
