Hey guys,
I need help. I just realized that I couldn't restore from CWM backup. I have several backups and I even tried diff version of CWM but all keep saying MD5 checksum match error.
What should I do?
Thanks

have you changed the name of them??
They need to be left exactly as the phone makes them
They don't, but you can't have spaces in the name of the folder.
If all else fails, recreate the checksum:
Code:
md5sum *.img > nandriod.md5

Run it via adb shell/terminal in the folder the backup is in
thanks rusty
Hi guys. I flashed a new baseband for my Optimus 2x. After that, I wanted to restore my backup and I get a MD5 Mismatch. How come? I didn't rename my backup or changed the recovery. Nothing!
hey, i had this not so long ago, its nothing more than a bad nandroid backup, nothing will fix it, you gotta reflash another backup or start over (i started over cuz other backups were too old)
You may be able to solve it with these steps:
1. Go to the directory of the backup.
2. Delete nandroid.md5
3. Recreate nandroid.md5 of all images with 'md5sum'.

This will allow you to flash a corrupt image, and is therefore not recommended
I got one just today, really annoying..
@kiljaken any idea why it happens, or how it can be avoided?

Not really no. All it takes is one changed bit in either file
My guess is you renamed the folder with a space, if so, try without it, if not then recreate the md5 as mentioned the MD5 with md5sum * > nandroid.md5
I always have this issue when I make the back up through Rom Manager. So I always make it now in clockwork recovery mode.

Works!!! Thank you..
1) rename folder (no spaces)
2) inside the folder, type "rm nandroid.md5"
3) then type "md5sum * > nandroid.md5

****ty. I don't know if there is a way to fix that. Do you happen to have the tweaked safestrap that allows flashing the nonsafe

If yes to my last question, just flash the stock bell 2.3.6 rom located in the dev forum. If no then you have 2 options. First it follow the steps in this thread http://forum.xda-developers.com/showthread.php?t=1404608
Or
Use motofastboot to flash a system.img, this will restore the /system, reroot, install bootstrap and then flash the already deodexed stock bell rom I previously mentioned to restore your /system, remove bootstrap, install safestrap and flash either that rom, or the rom of your choice into safe system and use safe system from now on.

You can manually find the MD5s on a computer and edit the MD5 file manually to make it work, its dangerous but it works... I've done it before

I've had that same problem in the past. How do you manually edit the md5 and how do you know what to change it to. Would I just run the md5 command in terminal and then unzip the backup and modify it?

The back up should just be a folder, open the folder, and run the MD5 Command in the Terminal on each of the backup archives (eg cache.ext3.tar, system.ext3.tar) and put them into nandroid.md5
The nandroid.md5 file should hopefully be laid out easily and just replace the hashes (random letters and numbers) with the ones you generated with the correct file's hash
And Restore away!

Method- Manually Altering MD5 Sums (Windows) (This guide might be off, Windows is not my home OS anymore...)
1. Plug your SD card into your computer.
2. Open up the directory where your back ups are should be /safestrap/backup/BACKUPNAME
3. Download this tool: http://www.pc-tools.net/win32/md5sums/
4. Drag system.ext3.tar and drop it on top of the applications icon
Write down that MD5
5. Drag data.ext3.tar and drop it on top of the applications icon
Write down that MD5
6. Drag cache.ext3.tar and drop it on top of the applications icon
Write down that MD5
7. open up nandroid.md5 with a text editor it should look something like this:
Code:
2ce2ec3c4beac74ba3fba94fb290ea21 cache.ext3.tar
12296836011615c7f2611e19c9390a78 data.ext3.tar
0589700a289739c448b6ff2e317d7951 system.ext3.tar
Replace the hash next to cache.ext3.tar with the one you generated, and repeat this for the other files...
IF nandroid.md5 does not exist, create it and do as mentioned above.
Then... Restore!
Sorry, I know this isn't the easy reflash you wanted but it's the only guide I can write at this time
(This guide was written going off of safestrap 1.08 you may have to change some titles of files)
Thanks and/or donate if I helped

You're gonna have to do the leg work to get the files and programs I mention because finding and linking while on my fine is a pita.
There is another option, the easiest of all, however it will remove you from the bell update path as we have no way currently of returning to the stock bell firmware. You can grab rsdlite and a fastboot package from the dev forum and flash that, it will fix it up but you are no longer on bell firmware. Up to you if you can live with that.
The other way is to grab motofastboot (google it) and a fastboot package from dev forum. Unzip the fastboot package into a folder and put motofasboot in the same folder. Motofastboot is a command line utility, it has no user interface. Open a cmd prompt (start button, run, cmd) and type cd C:\your\path\to\aforementioned\folder then run
moto-fastboot flash system system.img (I have the 32 bit version so mine is moto-fastboot32) I dont use windows, onlinux I have to precede the command with ./ so for me it would look like
./moto-fastboot32 flash system system.img
Your phone will now boot
Find zergrush easy root utility and follow the directions for it to root your phone, then install a bootstrap(or the tweaked safestrap that allows nonsafe flashing and then go grab the stock bell rom from dev forum and flash that. It is already deodexed.
this will keep you stock bell

First i 'ant to thank you
when i open my nandroid.md5 it was empty
i do the exact method, and create the 4 hash (cache, data, system, systemorig) on nandroid.md5 put it back on the phone, try to restore but ...no success. Still receive MD5 mismatch
when I return the SD carde to the pc, the nandroid.md5 empty again!

Linux or Windows? Esure you are safely ejecting (windows) or unmounting/ejecting (Linux) before removing the SDCard, I've noticed file changes sometimes don't stick if you don't safely eject.
I'm not sure if the method I'm giving is a soloution anymore with the reflash (That's not a bad thing!)
How can one go about modifying an OTA update? I see there is an updater-script file in-particular that checks the ckecksums of system files before loading the OTA... can this file be modified and what would be the procedure? Thanks in advance.
I'd like to modify the checksum values listed in this file to have it accept certain modified system files... What is used to calculate the checksum values?
Should be in Q&A. Reported.
Moved to Q and A
I found that sha-1 is used to create the checksums values in the updater-script file. In the assert check_patch lines the first value is the new file and the last value is original file. In the assert apply_patch lines same is true except middle value is size of new file in bytes.
Beyond this it looks as if the CERT.RSA, CERT.SF, and MANIFEST.MF files in the META-INF folder of your update.zip may be the next obstacle... I know this thanks to jhankinson thread on the topic.
I don't know if jhankinsons solution to simply deleting these and resigning would work on the Bionic? (I'm total noob in this regard.)
Perhaps we can edit the checksum values in these files. I found that in the MANIFEST.MF file checksums are simply SHA-1-BASE64.
Anyone know what is used for the values in the CERT.SF file? (it says it's sha1-digest but i'm using fsum-frontend with no luck getting a match)
And would I need to do anything with the CERT.RSA file? (Again total noob to how these are signed)
Hi,
I hope this is the write location for my post.
I have a HTC ONE rooted, android 4.3
I have a problem with my GPS: it doesn't lock any satellite. Reading on forum, I found that the problem may be the setting of gps.conf file in /system/etc.
In fact, checking it, I found that the NTP_SERVER set was for north.america, while I'm in Europe.
I would like to modify or replace it, but I'm experiencing some problem. Using Root Browser it seems to be able to modify it, but after rebooting the device it is exactly the same before the editing. I tried using other editors as ES File Explorer, but when I try to modify the file, it says "read only file system".
It makes me thing that also the other editor is not able to modify the file, since after reboot it is actually un-edited.
What do you think? how can I actually write in file system and actually modify gps.conf?
Thank you in advance
Let me add another detail: I tried to create a new empty file in the same folder with Root Browser. It seems to be able to create it, but after rebooting the device it desappears..so I guess I actually can't modify/write in the file system..

You need an unsecured kernel (/system writable) to write to /system partition of the htc one, not only root.. Otherwise, all changes will be reverted at reboot like you are experiencing.
Kernels for htc one here
And note that modifying/deleting files in /system will probably prevent you to install future ota unless you revert the change you have made. There is a md5 checksum of many files in /system before the ota installs. If the md5 cheksum doesn't match then the ota will not install. This might not apply to the .conf file you want to edit but just in case, make a backup of that file before. So if the next ota fail, you'll know why.
