[RESOLVED] Researching how to root - Official OTA_Supersonic_1.47.651.1-1.32.651.6

This has been resolved by using the flash lite exploit to gain root access allowing the misc partition to be flashed with a downgraded main version number which allows the old leaked Eng RUU we have to be flashed!
GUI for how to root
http://forum.xda-developers.com/showthread.php?t=720565
Old and Outdated information from the Original Post listed below for historical purposes ONLY
Who is Affected: If you've flashed the official OTA update on top of a non rooted ROM or your new EVO comes loaded with it, right now it appears there is no way to obtain root...yet!
What is Patched by the OTA: Through the radio.img which the OTA flashes, it updates the Main Version in the bootloader preventing Toast's root methods from working. It also flashes back the stock recovery, removing our root access in recovery mode and ability to apply .zip files. And last of all, the OTA patches the exploit hole in /system/bin/hstools used for unrevoked1 root.
Successfully eliminating all released methods of obtaining root access.
Conclusion:
after going through all these methods with a great helpful member of the unrevoked team, joshua_, this was the final answer:
[22:34] <joeykrim> cant see to find a method to RUU the phone back down ... ive tried all the methods ive seen. any methods i missed?
[22:34] <joshua_> ok, looks like we are hosed then
[22:34] <joshua_> we have a few more tricks up our sleeve sooner or later
Future:
If you have any suggestions/ideas, please post. I might have missed a method.
We will work towards obtaining root for those with new EVOs that have the official OTA applied and those who applied the official OTA.
Details of the tested known root methods:

Modifying PC36IMG.zip - using a hex editor to attempt at changing the MainVer stored in the android-info.txt, if any bit changes, it seems to fail the validation by the bootloader.

I tried almost all of these after the OTA hit my wifes phone. No dice. Subscribed to further updates on this thread.

I created a PC36IMG.zip file which contained the .6 releases wimax image and the android-info.txt file from the new update. I was then able to successfully flash it with hboot by placing it in the root of the sdcard and doing a down volume power on boot. It found the pc36img.zip file, verified it, asked me if I wanted to flash it. When I selected yes, proceeded to do so. It then reported the flash as having been successful.
I can't tell if the flash actually worked because I don't know where to check the wimax version info...
I don't know if this worked because the phone doesn't care to check the MainVer when flashing just the wimax image or if it did it because I pulled a fast one with the android-info.txt file swap.
I extracted the wimax image from the RUU_Supersonic_1.32.651.6_Radio_1.39.00.05.31_release_171253_signed.exe file.
I wonder if it would be possible to pull the same trick with the larger subset of images from the rooting pc36img.zip files. i.e. swap out the android-info.txt files...

im guessing the only reason it allowed you to flash a PC36IMG.zip which wasn't HTC signed is because you're using the hboot from the eng build of the PC36IMG.zip which doesn't check for HTC signatures on the PC36IMG.zip file. Not sure if it looks at the MainVer or not ...
once you're on a stock hboot, the PC36IMG.zip file has to be signed by HTC in order to flash!

I think in order for this to be patched, the bootloader code needs to be disassembled between the two versions to find out what bytes were patched and then either remove the code that checks for HTC signing or find a way to circumvent it.
We had to do things like this when working with mach_kernel when we got ahold of the first developer build of OS X for Intel. It was a pain in the ass and took weeks before we cracked the kernel.
There is even more risk with this though since tampering with the bootloader can definitely permanently brick devices.

since my frien did the OTA update yesterday and "bricked" his phone i have been trying to fix the phone (i have access to bootloader so it seems to me that maybe, just maybe i can save the phone) anyways, i have been getting a lot of the same error messages anytime i try to update/load any stock rom via bootloader.
what my question is, is there a way to take a 1.47.651.1 rom/image and put it into an ruu? i have looked all over htc's website, but they don't even acknowlege the existence of the evo, at least not that i can find.

Just curious here, regarding the above step, if you had access to a phone that was already rooted, could you use your sdcard in that phone to copy the files into /data and then transfer the sdcard back to the unrooted phone to flash it then?

Sorry for the long multi quote, there are quite a few good ideas and I wanted to make sure I explored each of them as far as the original poster intended.

interesting ... circumventing the HTC signature check would be perfect and essentially give us an eng build bootloader.
in the RUU.exe rom.zip files, the android-info.txt indicate the MainVer along with a separate hboot.img file. the official OTA didn't have an hboot.img file. It only had a radio.img file which must have updated the MainVer value.
Not sure where on the phone this MainVer value is stored? in the radio?
you're suggesting, compare the bootloader, which is obviously stored somewhere in radio.img as thats the only file being flashed thru the OTA which increments the bootloader version number, against an older radio.img to attempt and find which bytes were changed for the version number?
The radio.img files are all around 22mbs ... ugh
if we're able to find the change in version number on the radio.img, not sure how it would help in flashing over it?
i was kind of thinking down these lines...since the bootloader checks the version number of any file it attempts to flash, the version number is going to be the key.
if we're able to increment (or temp change) the main version number in the file being flashed w/o messing up the htc signature, that could work.

very clever concept!
i'm not 100% sure on all the different approaches in the suggestion, but here are the ones it prompted me to explore.
unfortunately, every time the /sdcard is mounted on the phone, its mounted as noexec, meaning no files located on the /sdcard can be executed like programs.
also the /sdcard is mounted with uid=1000 and gid=1015 meaning all files mounted on the /sdcard have their uid/gid overwrote so none of them are allowed root ownership.
without being able to "su" to root access, we aren't able to run any programs with root access.
trying to chownto flash_image to any reference file as root results in:
chownto flash_image /system/bin/chown
Can't change user/group to root!
chown root flash_image
Unable to chmod flash_image: Operation not permitted
if i missed the suggested approach, could you elaborate?

Oh boy...... I thought I was alone in this. I try everything I can and now gave up. Any one can rooted this new OTA please let me know. I really need to downgrade from this.

Made me think of a problem that happened with the Directivo a few years back...
ht t p://dealdatabase.com/forum/showthread.php?t=22154
I was looking around, trying to figure out some way to hack the hdvr2 w/o modifying the prom. I recalled something from the xbox-linux team's presentation for CCC, which was something close to "once you break the chain of trust, the box is forever compromised." I thought to myself: "self, if we can load one kernel via BASH_ENV, why can't we load a second kernel?"

So, is there a way we could compromise the kernel? If so, then...

Not really interested in rooting until froyo is working, and I could really use the wifi fixes this OTA is supposed to offer, but I'll hold off installing it until we know it can eventually be rooted.

i read thru the thread. im not clear on how they used BASH_ENV or any other method to load a 2nd kernel.
unfortunately, i think we have an extra layer of security that they dont. thanks HTC!
without nand unlocked on the kernel partition no data can be stored there including a 2nd kernel.
appreciate the link and info. perhaps the ideas or concepts will spur some innovation!

the thing about winmo ruu's (here's a topic i DO know well) is that they are always in a zip. you decompress the zip and have access to all the files. one of them will be the ruu, the rest are all the supporting files/images/rom. all of the android ruu's seem to come as on large exe that doesn't allow access to the files, it merely runs itself. in the winmo days if you got a rom with no ruu, and didn't want to flash from SD, you just took someone elses ruu and dumped the rom image in to the decompressed folder containing the ruu.
i appreciate the help joey, obviously you are busy with your own problems and a lot of people around here just throw you the old "SEARCH BUTTON" response. any help is greatly appreciated!

interesting again .. so the RUU .exe files for android, do have a payload stored in a rom.zip file which is dumped to a temp directory after the RUU .exe starts and before it finishes.
now, the rom.zip files have been pulled and posted in each of the two RUU .exe threads we currently have. these rom.zip files do contain all .img files which are flashed to the phone. the catch is though, just as the PC36IMG.zip files used in root, these rom.zip files seem to have a special HTC signature (checksum?) in their header.
if you open these rom.zip files from the RUU in winzip, it will error out, but using 7zip, they open just fine.
im new to HTC, this is my first HTC android phone and its almost been 4 weeks so this is as much as i know. it seems, if we're able to alter these rom.zip files either used in the RUU .exe or naming them PC36IMG.zip flashed thru the bootloader and the phone excepts them, we would be golden!
to help save you some searching and let you see what im talking about, here is the latest RUU rom.zip file

Subscribed, I was able to Order my EVO today so I will be watching for development. I pledge my donations to whoever is able to figure it out. I really appreciate the efforts of this community.

I second that pledge for donations! I, like many others here, updated while knowing that I probably shouldn't have. I knew better...

Subscribed.
Thanks for all the effort and work. I hope ya'll get it figured out.

dang, I just got my evo yesterday and got the update message so I thought it'd be ok to update it as I thought it might have been old.
Came home and was excited to do all my customization and tweaks, but w/ no prevail

So my local best buy will not give the phone to the customer without pushing the new OTA to it :/
Apparently all of the stores will be doing this per Sprint and HTC's request.

Try calling them ahead of time before picking it up and asking if you can just swing by and pick it up yourself and call Sprint to activate yourself. Tell them you are in a rush, make up a story, and see if they just let you pay for it and run.

Help with ftf extraction for 6.0 ROM.

Hi guys, I'm fairly new to this whole ftf system so I am having a bit of trouble extracting the boot.img out of it. I am working on a pure stock 6.0 ROM but need the boot.img extracted, I already got the system just need boot. I have tried using flashtool to convert the boot.sin to a boot.img and it tried making a 450 terabyte file when I clicked dump data. Any advice would be great. I also just tried renaming extension but that yielded a black screen upon immediate boot.
As a side note I don't think this is even going to work because starting from 6.0 and above the file system changed from system folder to the new format with the .dat files and that really makes things even more complicated than they already are.

DISCLAIMER: Since this is a third-party supplied file, flashing this file places any and all outcomes on YOU, the flasher (get your mind out of the gutter, thanks.) This file, though supplied by Samsung Kies 3, may cause issues or have undesirable effects. What these effects are, I have no clue. If you have a custom recovery, it will be overwritten with the stock recovery. Again, if you use this, you are the one responsible for any negative outcome.
​This the official stock ROM flashable via Odin. This took me a few hours to download several times and locate the temp directory that housed it. It is a 2.12 gig tar.md5 file. Since Samsung does not have an open source copy for us to download, I used Kies 3 to download it.
FLASHING INSTRUCTIONS:
Using the most recent Odin, put the file in the AP section and flash it.

Thank you so much it fixed my bricked device!

Thank you so much - Accidentally upgraded firmware and lost root and could not re-root. Worked like a charm and used kingroot to gain root again. You rock!

It downloads as a .RAR file if converted to .TAR, ODIN can not load it. How can the .rar file be used by ODIN?

The flashable .Tar file that you will use to restore your device via Odin, is located inside the .RAR provided in the download link. Once the .RAR file has been unrared/unzipped using 7zip, you will have your restore .Tar file that you're referring to. If you need to, you can Google 7zip and download it. The program is free and open-source, and it supports .RAR .TAR .ZIP etc. Happy Restore!

@jaywillsoul Please add to the OP that this firmware will wipe the device.
Thanks again for the firmware!

I downloaded the firmware, began to flash and Odin wrote "FAIL", and the screen after turning on is "Software update failed. Your device didnt update successfully. Use the Verizon Software Repair Assistant on a computer to repare your device and complete the update." But the Verizon Software Repair Assistant after this can not find the phone.

Thank you for this wonderful gift to the underdeveloped Core Prime! :good: worked for me and I was able to root afterwards!

Camera is broken.

Hello,
My device is the Mate 9 (MHA-L29C185B110) and I seem to have a problem with the camera.
When pressing the button to take a photo, the camera app restarts itself. I try again, but didn't work, to no avail.
I also tried to record a video. It seems to work, but the camera freezes but it's still counting, otherwise recording.
I have just recently flashed a custom recovery img (TWRP), the boot img on another thread that prevents the device from being automatically encrypted, and SuperSU root.
Do any of you have a solution to this problem?
Would this be because I haven't flashed Public_data.zip and Full_HW_data.zip?
And will this problem fix if I completely install the MHA-L29C185B172's firmware?

It could be a problem if you flashed a boot image for a different model. You need boot image for C185B110. It should work without hw and Public zips, but a lot of other things break without flashing those. Updating to C185B172 will fix it.
By the way, which supersu did you use?
If the one from the "Decrypt" thread in Guides you don't need to flash a pre-decrypted boot image, the installer does it for you.

As for the SuperSU, I think I took it from the full root guide w/o decrypt img, but obviously I had to use a decrypt img because of stock
SUPERSU-2.79-MATE9-init.d_support
For the boot (No force encryption boot)
This is probably where things went wrong. I flashed the wrong build image.

I had to use above link because I couldn't flash SuperSU since I don't have an external sd to extract it from (Since you have to format your data before flashing it)
I couldn't find the hw and public zips for C185B110, so if you have it, a link would be generous.
Would flashing stock boot img for MHA-L29C185B110 fix it?
and what would happen if i flash stock boot.img?
and do you have a decrypt boot.img for C185B110?
Thanks!

It would probably fix it yes, but no boot image or hw/public exist for B110 so I'm guessing it shipped with that build.

although it is not clear.
On manual update step A, do you need to download all three?
the base, the OS(windows) and the model?
and where do i put these files?
and on b and c on update zip
do i have to download two update.zip?
for example, C185B110 and C185B172
do i also need to download full ota instead of just ota? fullota is incompatible, says firmware finder on mobile

Yes, download base, os and MHA. Extract all to the same folder. You should only have one folder named HWOTA and the files/folders in that. If it extracts to a folder with the same name as the zips, enter the folders and copy hwota folder then go back one folder and paste/merge so you end up with one folder named HWOTA. Easiest way is putting it directly in C:\hwota\, if your windows version allows it. Else place it on desktop. (long file paths or a path containing spaces might make hwota not function correctly).
You need to download all 3 files (fullota update.zip, hw zip and Public zip), easiest way is using firmware finder to download. Either mobile or the pc version. For pc go to the common base tab and search for your model and then download the build you want including public and HW zips.
You only need to download the fullota update, hw and Public zip of the build you're updating to. If you're on b110 and going to update to B172 you only need to download B172.
Rename the files according to the guide (update.zip, update_all_hw.zip and update_data_public.zip), place them in either hwota/update folder or make a HWOTA folder on your sdcard and put the renamed files there.
When running hwota, select script update folder or sdcard update folder depending on where you put the files. Select same model update.

One last question:
Does it have to be FULLOTA, not just OTA?

Question (SOLVED) OnePlus 9 LE2115 C.62 Bootloop

Hey all,
I have an LE2115 OnePlus 9, running the C.62 version of ColorOS 12. I followed a guide I had found and seen posted by members here to root my OnePlus 9. I originally was trying to boot into TWRP to perform a full backup, however someone here mentioned that TWRP no longer works for this device. I followed this guide exactly step by step, however now my phone will show the splash screen, vibrate and show it once more, and then boot into recovery. The boot reason states: "fs_mgr_mount_all". Just to clarify, I patched the boot.img and vendor_boot.img via Magisk on my device, and flashed the two boot files along with the vbmeta.img, as shown in this guide.
Is there any hope getting my data back? I am aware I can use MSM tool to restore functionality to my device, but I am much more concerned about the data as I have a lot of important 2FA information on here. Any help would be insanely appreciated!!
Edit:
After 7 hours of flashing different images and trying different methods, I finally got it to boot again! I had been trying many things, but for some reason it worked after I repeated something I had done many times already. I simply flashed dtbo.img, then vendor_boot.img, and lastly boot.img, and it magically worked! I used the C.62 images created with this amazing tool! The issue was that I flashed the C.48 images, which were provided in the article. They didn't consider some people might be running on C.61-C.62.

If it isn't a bother, can you explain what kind of commands did you run to extract files from the incremental OTA? I already have python and the latest PIP for it, I also downloaded the tool folder you linked but have no idea which commands to run and where do I put the OTA payload.bin. This tool isn't as simple as the one I've been using to extract from full OTA zips back in the OnePlus 6 days.

Yes of course. I used the OnePlus OS Update Tracker to get the downloads for the firmware.
C.48
C.61
C.62
Dump the C.48 payload and place the dumped images into a folder called "old" in the update_payload_extractor tool. I ran this on Linux so it made me remove the .img extension from each image, but it might be different for you. Place the payload.bin of the C.61 firmware into the root of update_payload_extractor, and perform
Code:
py extract.py payload.bin
After it finishes, you will have a new folder called output. which contains the upgraded C.61 images. In my case, some of the upgraded images were 0 bytes. Copy all of the files that have a normal size from output, and paste them into the "old" folder again, overwriting the C.48 images from earlier. Then place the C.62 payload.bin into the root again, and run the same command. Now the output folder will have the C.62 images!
You can repeat these steps if you have C.63, simple copy from output -> old and extract the new payload.
