Main Version Is Older! Update Fail! Message

Hi,
Thanks in advance for anyone who tries to help me.
A few weeks ago I tried to gain root access to HTC Eris. I followed the prereq and part one of the guide but stopped there. Rebooted my phone, checked the version (2.1) and went about reinstalling apps and such.
Now I want to install a different ROM so I went back and tried to start from the beginning and put PB00IMG.zip on my phone, went to hboot, let run but then I get the message "Main Version is older! Update Fail! Do you want to reboot device?"
So when I move onto III in the walk through, I get an error on the command
adb push flash_image /system/bin
It would seem like I've lost root right? Is there anyway I can check to see if I accidentally installed the leak w/o root?
Thanks,
Nate

Easy way is to do
adb shell
if the prompt is
$
your likely on leak
if the prompt is
#
your on root.
Once your on root, flash recovery.

I am anticipating the next question, so here is your answer. If you did indeed root your phone, you should have loaded a recovery image as jcase mentioned.
First, load the new ROM onto the root of your sd card. Next, power off your phone. Then, hold down the vol up button and turn on your phone. It should boot into the recovery console. From here to load another ROM, you need to perform a wipe and then load your new ROM by flashing. You should see a Wipe and Flash from Zip menu option in recovery.
In the Wipe menu, choose the first two options in order (factory reset and cache). Wait for each to complete. Next, pressing vol down should get you back to the main menu. From here choose Flash from Zip and then select the ROM zip file you loaded onto your sd card and wait for the update to complete. Last, reboot your phone from the menu.

When you say "likely" you pretty much mean "sorry but you're non-rooted and I don't want to be the one to tell you" ?

You have 2.1 from the OTA, or on phone at purchase or from an image you flashed?

If you still have a $ then you most "likely" loaded a leak rather then root. If you get a # then you are in luck.
I don't remember if the the leak that included su had adb set to root by default.
good luck.

I followed a guide a few weeks ago that must have been for the leaked version of 2.1.

Yes, sadly you are now stuck with the Leak.
Stay tuned as the devs are still working on it.

Does anyone know what HTC says about all of this? Can I send the phone back to them and have them "restore" the phone to factory settings?

Technically, modifying your device would void warranties. Even if they could "restore" the device, it would still have the newer bootloader that is causing the rooting issue. Some people have "lost" or "broken" the device bad enough that they could get a replacement from Verizon. However, there is mixed results as to what bootloader the refurbished devices come back with.

I posted before about the safety of re-rooting my eris from 1.5 to a rooted 2.2 rom, and due to lack of responses on any forums over the web, I jumped the gun today. First off my Eris after un-rooting it, wouldn't take the OTA update for 2.1, it downloaded and verified that, but after it rebooted, it was still at 1.5 saying no new updates are available. I cannot download the eris 1 click root app as it's only for 2.1 I'm assuming because it says it's not compatible with 1.5 firmware when I download it. I tried to follow this guide [Walkthrough] From stock (1.5) to rooted 2.1 (update - new link) - xda-developers and when I installed the PB00IMG.zip it downloaded but failed to flash and the screen read "Main version is older". I tried this guide All-In-One Auto-Root Script - Page 4 - xda-developers and when it says it's flashing the root image, it goes straight to a screen with only two options "recovery" something and "fastboot". None of which are listed as options in the guides. I am just trying to root my 1.5 eris and flash the KaosFroyo V3 eris rom with Amon Ra's recovery image. Thanks if anyone can help my problem, or shed light on the situation! Sorry if there's been a fix to this problem already stated, I've desperately been browsing many forums and hundreds of replies to no avail. Thanks again.

It looks to me like you got a pretty reasonable answer to the same question over on Android Forums

I need to go back to stock recovery, but I can't find a working link for it.

Download the latest RUU from htcdev.com (should be 1.29.1540.16).
Run that file and you should be good. Once installed, it'll give you the system update notification.

For that, you need to get into bootloader. Using fastboot, issue the command:
fastboot oem lock
But, one more thing - before you try this, are you able to get into your phone at all? Have you tried the factory reset in settings? If possible, try that first, before you lock your bootloader & run RUU.
If you do run RUU, after your system has become stable, to unlock it back, follow the instructions in "Unlock Bootloader" in htcdev.com

OK, so my phone works fine, and I can boot into recovery now, but it's CWM. If I do a factory reset will it get rid of CWM? Because that sounds much easier. Also, I'm not rooted yet.
I found this DL for the RUU as an .exe
http://www.androidruu.com/getdownload.php?file=M7/RUU_M7_UL_JB_50_BrightstarUS_WWE_1.29.1540.16.exe
If I use that, do I need to put it on the phone or do I just run it from the computer?
Thanks again for all your help.

If it is CWM that you are running, no way you are going to get the latest HTC DE update. If you want the latest HTC DE update, you are going to have to wipe out everything and put in stock.
For bringing your phone back to stock:
1. Download the RUU.exe file onto your windows computer.
2. I am assuming here that you have all the latest USB drivers installed on your windows computer. I am also assuming that you are able to get to the fastboot prompt and are able to see your device in your windows computer.
3. To check if your device is visible in windows, issue the command fastboot devices while in the fastboot prompt. To get to the fastboot prompt, keeping the volume down button pressed, press & hold the power button and do not let go until you see the fastboot screen. Then issue the above command.
4. Then issue the command fastboot oem lock. This will lock your bootloader.
5. Next reboot back into bootloader
6. Then run the RUU file from your windows pc and follow the instructions on screen.
Since I have to say this, I'm saying this:
As always, back up all your data. And do so all this at your risk. Make sure you read the various related posts and understand what your are doing. If you brick your phone, I am not to be held responsible.
There - having said all this, I think you should be okay. Good luck.

SuperCID (11111111) is often disabled for OTA updates. You need to update your CID to the one from the developer edition: BS_US001

Very strange as there is the "small" update from .16 to .17 first. And this one is out since a long time. Honestly when the CID and the rom version is correct I have no idea why it doesn't want to update. But there is always a strange logic how the auto-update works.

Can't boot to Download Mode

Yes, I've searched and worked for hours on this. I keep hitting a brick wall.
D800, rooted, TWRP, KK rom.
Even though I didn't ask for it somehow the OTA must have installed because my phone rebooted and then was stuck in recovery boot-loops. I can't boot into download mode which means I can't restore to stock or do anything. Do I have any options or is it time to head to the ATT store and try a warranty replacement?
Thanks in advance.

I cant download the firmware restore file in the op but that would be the best place to get it. if there is a way to extract the image from the restore file thats how you would get it, example is a tool called unruu for htc devices. other wise it has to be directly copied from the device. if youre lucky the file system includes a path like this
Code:
/dev/block/platform/*something*/by-name/
you can see that with a file explorer like root explorer. With in that path there should be a bunch of partitions listed by name. im not certain of the name of the one id need. it could be aboot or boot or something else.
to copy a partition for me to use, youll need adb shell or an android terminal emulator installed and root.
run terminal emulator or run adb shell
Code:
$ su
give shell root access
# dd if=/dev/block/platform/*something*/by-name/aboot of=/sdcard/aboot.img
or
# dd if=/dev/block/platform/*something*/by-name/boot of=/sdcard/boot.img
youll then have a boot.img or aboot.img on you internal sdcard. let me know if you can get those that way or by extracting it or if you can send me factory restore file and i can try to extract it myself.
I just wonder how well twrp or something will work because of verizons habit of having locked bootloaders.

it looks like the bootloader is locked, shocker right! it is verizon after all. not sure how locked down it is.

I see the issue. the line "give adb root" was a comment not something to actually run.
commands excluding the line starting with give. and replace *something* with the proper path. for the htc m9 its
Code:
/dev/block/platform/f9824900.sdhci/by-name/
If it doesnt work i can at least get the device tree started.

I know enough stuff to keep me out of trouble with adb/flashing. And based on where I would need to start to try and pull the boot file, I'm lost haha. Anything else and I'd be happy to help with!
Sent from my VK815 using XDA Free mobile app

So my tablet today prompted me to update to 11A. But since it's rooted it didn't go thru. Does anyone know what we can do with that info? Like to keep root and update?

Came here looking for the same. There's a chance that even after update could root, possibly like g4, but no guarantees. And without ever having a recovery, the only possibility would be with flash fire, but still no guarantees. And we would need for someone to upload a system image to rip for that...

Has anyone found a recovery that works on the VK815 on 5.0.2?

I am wondering if anyone has found a way back to stock so that we can take the upgrade to 11A

I figured since its a Verizon tablet, the boot loader would be locked and I lack the knowledge and experience to bypass it. However I could still get a device tree started

Wouldn't 'dd' with root privileges be enough? It might not be script friendly but ... I've used CM with the stock boot loader before on other phones and the boot loader wasn't a show stopper.
Anyway, it you need an image from me; I'll work it in the schedule.

I think everyone is being cautious knowing how Verizon likes to censor things. Yes, censor is the correct word. They are trying to tell VK815 owners what they can and cannot put on the VK815 owner's VK815.
I'd like to see a dedicated version of linux for the VK815. Later today I plan on emailing LG on that and a few other things.

To obtain the image yes that's sufficient, its when you try to replace the recovery or rom is where the locked bootloader causes issues.

I was thinking that with root privileges one could 'dd' over the boot loader with a new one.
Have you (or do you know anyone who has) been able to compile android-5.1.0-r1 with the LGVK815_Lollipop_Android.tar.gz added on? My attempts fail with a "make: *** No rule to make target `out/target/product/generic/obj/STATIC_LIBRARIES/libtune2fs_intermediates/export_includes', needed by `out/target/product/generic/obj/EXECUTABLES/updater_intermediates/import_includes'. Stop." I'd feel better if I could successfully compile the stock version.

BootLoader Unlock (both ZE551ML and ZE550ML)

Congrats to all ( both ZE551ML and ZE550ML users), bootloader has been unlocked without connecting to ASUS servers.
2.19.40.20 is also unlockable
New update 2.19.40.20 can be unlocked as well and Asus did not patch the hole. Thanks to @oxydius7 for confirming this here
Bootloader of both ZE550ML and ZE550ML can be unlock if rom is on 2.19.40 or 2.19.40.20
Lets discuss, problems and unlocking related experience here.
How to unlock bootloader:
1. Update to 2.19.40.18 or 2.19.40.20
2. root it
3. make sure adb is insatlled and working
4. enter the following commands in cmd
adb shell (press enter)
su (press enter)
getprop ro.isn > /factory/asuskey ( press enter)
reboot bootloader ( press enter )
Phone will restart in bootloader and after updating itself phone will restart again and ASUS splash screen will be white ( locked bootloader has black screen, you will see difference by yourself)
5. download black splash screen for 551 from here
https://mega.co.nz/#!IlMGiZ7I!kepXRFda7cgNPWHQovkCZaMaD2zVF4UufAJT6YEDU3k
or for 550 from here
http://forum.xda-developers.com/attachment.php?attachmentid=3376376&d=1435127302
6. navigate to adb folder open cmd and type the following commands
adb reboot bootloader (press enter)
fastboot devices (press enter)
see if device is listed, write following
fastboot flash splashscreen splashscreen.img (press enter)
restart your phone and now black splash screen is back. Congrats your bootloader is now unlocked.
If you follow my steps there would not be any data loss from internal memory and sd card, but i will advice to take a backup in case if you are out of luck

Great news. Looking forward to start Breaking this baby.

Is it possible to do this on 2.18? My phone just refuses to update to 2.19 no matter what I try.

I dont belive so, the needed files are part of the 2.19 update. I also had a problem with the update so I had to reset phone, then sideload a full copy of 2.18 and then sideload the 2.19 update and reroot phone.

Alright, I will try this right now and see if it updates, thank you for responding. This is the only phone that I have been having problems consistently with. It is kind of making me feel like I should of went the extra money and buy a device from LG or Sony.

same here i always bought samsung since s2, i can understand how this phone messes and waste a lot of timw with small things which can be done in seconds

I can reconfirm this process works with latest update. Thank you!!

Followed the instructions, works like a charm, nothing got wiped out.
:good::good:

Wow. The amount of work achieved by XDA members never ceases to amaze me!

thank you very much to all of the developers who helped unlocking the bootloader!
