[Q] Stock Recovery

Hi all.
Getting slightly confused about which stock recovery i could use if i wanted to. Would someone kindly point me in the right direction? It feels like i have read a billion posts but i have information overload.
I am with 02 uk. I have included the getvar all below in case it is needed.
C:\adb>fastboot getvar all
(bootloader) version: 0.5
(bootloader) version-bootloader: 3.18.0.0000

Any help is appreciated..

Version-main is empty as a result of flashing a buggy TWRP and CID is superCID thus hard to tell. MID would fit for 154.401 as well as 2.22.401 recovery. To be sure a question. Are you still running stock ROM. If yes you could check setting > about phone > software information > software number. If you are running a custom ROM this information is likely not to be valid. o2 Germany stock ROM e.g. has a x.xx.207.xx version number

Hi
I am running Android Revolution HD.

If you flash Philz Recovery, you will at least be able to get your version-main back and then you'll be able to look for that version in the Stock Recovery Section.
You CID should probably either be O2___001 or O2___002..

Hi John
Can i install Philz alongside TWRP?
Also i downloaded Build prop editor and under "ro.aa.cidlist" has the following cid numbers
htc 001
htc e11
htc 102
htc 203
htc 405
etc. Are they relevant?

Philz will overwrite TWRP as you can only run one recovery at a time.
This list names CID of different carriers.

Will flash Philz shortly and hopefully that will provide me with Main version. However one last question. Will the Harman & Kardon prevent me from going back to stock?

How long ago did you get the phone, and have you done any OTA updates since you've had it.
If you bought it before March/April (ish) and haven't done any updates then it's likely that you're on the 1.12.206.17 version.
If you've done an OTA since then you'll probably be on 1.54.206.5... in which case try this, this is the stock recovery for 1.54.206.5..
There are Backups for both versions in the Stock Backups Page.
This is for the 1.12.206.17
https://docs.google.com/file/d/0B_9hxg3el0DpN2xpbkx6NGkwRE0/edit?pli=1
And this is for the 1.54.206.5
https://mega.co.nz/#F!odoimZRD!fXWN36-1i3AUdkAHcgfy_A
I'm not trying to mess you about, honest, but you'll to go back to TWRP to use them. :angel:
...John...

Definitely had ota since getting phone. Only rooted in the last 10 days. Thanks for all your help. Will use 154..... If I decide too.

HBOOT 3.18 ? You updated the OTA to latest 4.4.3?
If so then you're fresh out of luck, I don't see any 2.xx.206/207.x stock recoveries for O2(UK/German) devices. Even on the German forum they only have the 1.54.206.5/10 ones.
Only choices you have then is to either:
1) convert - Seeing as you are S-OFF
2) roll back to older version and go through update again this time taking a backup of stock recovery. Flash old Firmware, you can probably get tutorials on here somewhere on how to do it.
3) scout the mobile phone boards(locally) and see if someone can drop you a stock recovery or
4) Wait until someone uploads a stock recovery.
In order to provide these stock recoveries, we need people to upload them and share the links and as you can see, guys like you don't do it! So we're stuck with no backups to share with guys in similar position like yourself
Good Luck!

I take it they rolled out the latest 4.4.3 for the customers. Honestly I wasn't keeping tabs on whether they rolled or not. I just saw the HBOOT version and thought that he might have updated to 4.4.3 because as far as I know it only changed to 3.18 with 4.4.3 before then it was 3.16. I could be wrong though?
I suppose if the OP didn't flash any custom ROMs etc he could just go to settings > about > software information, and confirm either way

He's already on Android Revolution HD.
There's a link to the 1.54.206.5 firmware on the Android Revolution Site, but would it work with the wrong version-main in the android-info.txt
http://xda7.androidrevolution.org/db_mirror/Firmware/index.php?dir=HTC/HTC_One_M8/206/
I think the way I got my version-main back, was to flash a different version stock recovery, it wouldn't work because it was the wrong version number, it just kept dropping back to HBoot, but it did bring it back when I then reflashed CWM / Philz.

What I meant was.. You probably had the right recovery or at least knew what one you needed.
It's a similar situation to one that I was in the other day. I had no version-main, so I didn't know which recovery to flash. So I took a guess and flashed a stock recovery for my device, it didn't work because it was the wrong one, but it did give me my version-main back in getvar all.
I then flashed back to Philz Recovery because I had no recovery. Once I knew the version main, I managed to find the recovery... :good:
...John...

To confirm I am on 4.4.3. I will see what comes along in near future. Should of read a few more posts before rooting.. Again help appreciated.

Hi Rlumby.
I was just wondering why you want to return to the stock recovery. Do you need to to send it back, so you need to return it back to it's original condition or do you want to keep it open for OTA's, etc...
Since you are S-Off and SuperCID, I don't see any reason why you couldn't flash another carriers firmware, or like BerndM14 said, maybe convert it to a Developer Edition or a GPE Edition.. It will wipe everything so if you do go down this road, make sure you back everything up first...
...John...

Hi John.
It was just an option should I choose to. Now you mention it I may go for developer edition. Will check out what's out there.

Sure you can download it and extract OR you can just go COLLECTION of Stock backup's and download the stock recovery. Both the 2.22.709.3 and 2.22.709.4 is in that thread.
Flash back the stock recovery and lock bootloader seeing as you're S-ON. Do the update and you can go ahead and do what you want again. You'll probably lose root yes, you can just get it back again no problem.
Edit: Not needed to relock bootloader as mentioned by ckpv5 :good: :victory:

There is no need to extract the stock recovery from the OTA, we have stock recovery 2.22.709.3 and 2.22.709.4 here : http://forum.xda-developers.com/showthread.php?t=2701376
There is no need to unroot as you will lose root anyway with the update, then you need to re-root
And most important is there is no need to lock bootloader. Leave it unlocked.

You beat me this time
But I need to correct one thing, there is no need to relock bootloader for OTA whether it's S-On or S-Off.
Relock bootloader for S-On is needed only when flashing signed htc firmware or run RUU

Ah ok, I can remember in the stock collection thread it was mentioned that we needed to relock if S-ON, I did see someone else say different but wasn't sure about it. That's cool then. :good:

another 2 really quick questions:
1 - My HTC wont go into debugging mode. i enable it, there is that little window popping and saying if i want to accept this computer, i checked "YES", and then nothing happends. even ADB Devices wont recognize.
2 - You guys recommend s-off? whenever HTC releases Android L, having S - Off would be good or bad?

1. make sure your ADB version is not lower than 1.0.31
2. S-Off is good and bad..
good for people who knows what he is doing
and bad for people who doesn't know what he is doing as he can easily brick his device.
When HTC release Android L... it got nothing to do with S-On or S-Off

You are not reading.....it's been said 2 times at least :
1: you do NOT have to relock for an ota !
2: what you need is
- stock rom with UNMODIFIED system (root is NO issue)
- stock kernel (boot.img)
- stock recovery
Then you can update !

It's nothing wrong, that's the stock recovery.
You're not supposed to reboot in recovery mode.
Just reboot your device, check for OTA and let the system do everything for you.
Do you have the correct stock ROM for your current firmware ?

This is the reason why you have that problem device not booting.
You can't use a very low version recovery like 2.22.709.4, it won't work.
You can use only 4.24.709.2 recovery and nandroid backup or in case you want to go lower to do OTA again, you can use only the lowest is 4.16.709.9 recovery and nandroid backup. Cannot go more than one version lower.
Do you still have the current ROM 4.24.709.2 backup ?
What was the problem with 4.24.709.2 that you seek advise from some people who simply give wrong advise ? Yours is the latest update lollipop 5.0.2 .. remember that.
You can try the one posted here : http://forum.xda-developers.com/showpost.php?p=59953829&postcount=5068
See whether you can download it or not.
If cannot, I will see whether I have time to upload my own backup for 4.24.709.2

OHHHH
I don't have any problem with 4.24.709.2 like you said I just received wrong advice
I don't have the ROM 4.24.709.2 backup, I will try to download the file with the link that you provided me, once the file was downloaded I just need to flash with TWRP is correct?

I have no idea about that backup whether it is for TWRP or CWM. But backup is for restore not flash. Unzip on PC and transfer to custom recovery backup folder. Boot to recovery then restore the transferred backup
I don't understand why you flashed the wrong stock recovery when your latest ROM has no problem.

[Q] CM11 M9 to Stock

Hi,
I have an UK HOX which is running CM11. I am giving it my father and want to revert to stock beforehand. I don't have a nandroid backup & can't seem to find one which will work. Is this possible or will I be stuck on CM?
I'm currently on HBOOT 1.36 & radio 5.1204 (not sure if that's relevant). Please let me know if there's more info I can provide.

Hi just read the thread properly, I have confused you in my pm, Thant is right, your on hboot 1.36 so you need my nand not glenbrownies. This is the stock nand from before the jb update which has the hboot version 1.1? You will need to update in settings about phone check for updates and you'll then have sense 5 installed.
You can install a nand which has a lower hboot version but not a nand that has a higher hboot version.

No worries. Thanks a million for the help
Can I just get one last noob question out the way - in the nandroid backup folder, are they both the stock boot.img and recovery.img I need to flash after restoring? Or do I need to find a separate stock boot & recovery img?

I've successfully reverted back to stock. Only issue I have now is that the official OTA update won't install. It downloads and boots into the stock recovery, then about a third of the way up the progress bar the process stops and the recovery icon changes to the red triangle with the exclamation mark in it.
I've also tried it again after doping a factory reset with no luck. Any experience with this happening?

Just flashed the recovery from the firmware.zip file & the OTA update fails at same stage.
My bootloader is unlocked, should it be relocked for this to work?
Edit: Relocked bootloader & tried with the same result. I noticed the hboot img file in the 'firmware' zip is a higher version than mine (1.36) ... Would it be worth flashing this then trying again?

don't use the recovery from OTA update use previos one or this for your main version and must be recovery for your main version
other way is to lock the bootloader flash firmware.zip then flash custom rom or stock nandroid backup. But you need to see your main version again after flashing the zip

Awesome, that's worked! Got the JB update restored, runs great! It does say there's another update to install but I get an HTC error saying basically the device is rooted (I installed the new recovery & relocked bootloader, it's def not rooted anymore) but I don't care to be perfectly honest.
Thank you guys so much for all your help!

I will use also Helium to backup application, and I will backup all my files on a cloud.
Mod:
Which are the steps (and relative howTo) for modding the M8?
Install bootloader, recovery, root, going s-off, install rom...
Restore:
For returning S-ON, I have to buy a Sunshine License, right?
For restore a nandroid backup? What could I do?

Hi. There are a lot of topics that cover exactly what you need. Look for them. You can start here...

I can't move in all those guide. I'm a bit confused ...

ckpv5's file is useful, yes. The other files, NO. Reason being, you can't downgrade to a lower software number (2.22 is lower/older than 3.31) unless you have s-off.

Mod:

In summary:
1) Backup personal data by method(s) of your choice. Helium is fine.
2) OTA update to Lollipop (version 4.something)
3) Unlock bootloader by HTCDev.com
4) Install current version TWRP
5) Backup your stock ROM by making a TWRP (nandroid) backup
6) Flash custom ROM
As long as you take the OTA to Lollipop as indicated (to update the firmware - otherwise current ROMs will not run correctly on your phone), you don't need s-off to flash a ROM.

Restore:

As mentioned, you don't need s-off to flash a ROM.
To make the phone s-off, you would have to had already done sunshine, so going back to s-on, its a foregone conclusion that you already paid for sunshine.
To restore a nandroid backup (one you created, per the above step 5) you just boot into TWRP and select RESTORE, and select the desired backup file.

Keep reading and understanding until you get comfortable with the terms, procedures, etc.
I know it can be intimidating (and some guides have some outdated info). But its important you properly learn and understand before undertaking the activities you described. Being spoonfed the steps is doing you no favor, as it shortcuts the learning process; and just leaves you will enough knowledge to screw things up.
If you have specific question, just come back here and ask (as you already have); and we'll be happy to help.
But you are not any different for anyone else here. We all had to start at the same point at one time.

Before you do anything else, do OTA to update your device software version to 4.20.901.3 first.
If you need 4.20.901.3 stock backup and 4.20.901.3 stock recovery, they are available here : http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860

No problem as long as you keep it on KitKat. You can't install any lollipop based custom ROM.

It is advisable to revert everything to stock with no root (that's why a stock backup is there) to avoid problem when going through OTA process.

Then, to OTA update, for example, to Android 6.0, I have to restore my Nandroid Backup or I have to use your file, right?

Then, do you advice me to OTA update, unlock bootloader, install recovery, execute a nandroid backup, install a modded rom?

To do OTA to Android 6.0, you still need to do OTA to lollipop first because your current one is KitKat. Doesn't matter using your own nandroid backup or mine as long as the nandroid backup is non-rooted.

As most of the modded ROM are lollipop base, you need to do OTA to lollipop, unlock bootloader, install latest TWRP 2.8.7.0 recovery, make a nandroid backup (you need this for next OTA) then install custom ROM.

Firmware.zip - seems no one uploaded them, reason is I believe firmware.zip has no real purpose. Most of the time, people use the firmware.zip only to extract out the recovery.img
And I don't see why you need to use firmware.zip

Running android 4.4.3 with root; how to upgrade to latest Marshmallow and retain root

As per the headline, I've got an HTC M8 that I rooted shortly after purchasing in 2014. When the Lollipop OTA upgrades came out, I was reading mixed reviews about battery life and system performance, so I used a quarantine app to freeze the auto-update app so that it would stop bothering me to upgrade all the time. Now that Marshmallow has been out for a few months, the reviews seem positive and say that battery life is improved and the device is just as responsive as it used to be, so now I want to upgrade my device to Marshmallow.
I'm more or less an android / phone newbie - I mainly just use my phone for email, web browsing, driving directions, taking photos and the occasional app like banking, I'm not into heavy customisation but would like to retain root for the ability to uninstall shovel-ware, freeze programs and so some minor customizations.
Anyway, since I have 4.4.3 Android rooted, which process should I follow to get Marshmallow rooted, while retaining all the current data on my phone (apps, phone contacts, etc)? Do I need to do an OTA upgrade to Lollipop, and from there do an upgrade to Marshmallow?
My phone is an unlocked HTC M8; it's not a GPE or other branded vendor phone. I live in New Zealand and I bought it parallel imported, I think it was originally from Hong Kong.
I already have some of the bootloader/recovery stuff sorted out from when I rooted it the first time. Going into bootloader this is what prints out for me:

Please upgrade your firmware first through RUU to flash other ROMs.

Would this be the same as stock OTA?
Also wouldn't flashing a ROM destroy all my apps and data?

No the ROM won't be same as stock OTA,there are more or less modification in every ROM.The way you can exactly stock update by flashing RUU.
And yes all your apps and data will be wiped.Why don't you try titanium backup?you can backup all apps and app data with it.

First off, you need to update your recovery. Go with TWRP 2.8.7.0 or higher.
Secondly, you can update and keep all of your data. Make a nandroid backup with your new recovery, then run the appropriate RUU to update, or go back to complete stock and take the OTAs that will get downloaded to your phone, then restore your nandroid. The new firmware won't get overwritten by restoring your backup. That partition isn't included in the backups.
Hook up your phone to your PC, get into fastboot, and enter the command fastboot getvar all. Post the results here (minus your IMEI & serial# ~ that's private info) and I or someone else here will direct you on the easiest way for you to update.

No, a nandroid is a backup that is made by recovery (TWRP). It can back up the stock ROM, and user data (which is the goal in the above posted suggestion). After you update, you can restore the user data (but you don't want to restore the old ROM, since the goal is to get to MM - that part wasn't clear in the previous post).

Since you rooted, you can't simply unfreeze the updater and OTA.
OTA requires restoring the stock ROM (never rooted, unrooting does not work) and stock recovery (you have TWRP now, which is a custom recovery). RUU is an easy way to restore the whole phone to stock condition.

Ok, so if I'm understanding this correctly:
* To use the OTA updates, I need to have a stock ROM, as well as a stock recovery (not TWRP)
* I can make a nandroid backup of user data in TWRP, and then use RUU to go back to a completely stock phone
* From there I can do OTA upgrades to get up to MM
* Then I can install the TWRP recovery and restore my user data
Another approach might be:
* Backup the user data using TWRP
* Use an appropriate RUU, or series of RUU's, to upgrade to MM, without using any OTA updates at all
* Restore user data
It seems like path 2 would be easier and less risky of making a mistake. So what RUU's do I need? The output of "getvar all" is available a few posts up.
Also is there an easy guide somewhere for how to upgrade to a newer version of TWRP?

Yes, path 2 (RUU) would be easier in your case. But unfortunately, I don't think you version has RUU. You'd be looking for an RUU for 6.12.709.4
That being the case, you need to resort to path 1 (return to stock and OTA updates).

Fastboot install method is simple and reliable. Instructions and TWRP files here: https://twrp.me/devices/htconem8gsm.html
Since you already have fastboot working, just put the TWRP .img file in the same folder as wherever fastboot.exe is located, then connect the phone, and run the command:
fastboot flash recovery twrp.img

Right, I've just sat down to try and do this, and realised that I'm still not clear on what I actually need to do.
It seems there is no RUU for my phone for MM, which would be RUU for 6.12.709.4.
So instead I need any RUU that suits my phone for Kitkat or Lollipop, and then do OTA upgrades from there? So what RUU versions should I be looking for, since 6.12.709.4 does not exist?

There is no RUU for your device version. You can only restore to stock ROM and do OTAs up to the latest.
Your main mistake (I remember you have the same problem before) is restore your backup data after OTA done. Restoring old data that removed your apps like calculator & flashlight.
What you need to do (correctly):
1. Don't use that TWRP 2.7.0.2 .. install 2.8.10 or 2.8.3.0
2. Make a TWRP backup of your current data/system/boot
3. Restore non-rooted backup 2.22.709.3 (boot and system only - use your current data)
4. Install 2.22.709.3 stock recovery
5. Do multiple OTAs up to the latest 6.20.709.2
You'll upgrade your ROM and firmware but still have all your data intact.
All files needed are here : http://forum.xda-developers.com/htc-one-m8/help/tutorial-how-to-stock-stock-twrp-t3086860
If you happen to wipe all data & system before restore 2.22.709.3 (as per step 3), you can restore data only from your own backup before step 4 ... remember to restore your own data before OTA, not after OTA (if not you'll have your old problem again)

I know this is an old thread but just for info, I found RUU for this particular CID HTC__621 on another site
Source: Removed to avoid confusion
RUU Link - Removed | Wrong file, was not an RUU
Though I'm not sure whether it is official or not (signed or not) as the name of the file is really small.

That's not RUU ... it's a ROM flashable zip. Maybe you better remove the link so it won't confused others.

Right, I've finally gotten around to doing this, and the process was pretty straighforward. Thanks very much for your excellent help ckpv5.
So I'm now on 6.20.709.2, but I don't have root. How can I root this phone?

Install latest TWRP 3.0.2-0 - https://dl.twrp.me/m8/
Install latest stable SuperSU 2.65 in recovery - https://download.chainfire.eu/921/SuperSU/UPDATE-SuperSU-v2.65-20151226141550.zip
It's better to install custom kernel as custom kernel has system write protection disabled.
