Guest DJHope Posted January 21, 2003 Report Posted January 21, 2003 Keen to have good backup of my SPV decided to use my (now redundant) 64MB MMC card todo a backup easy enough, turnoff, tunron holding record, says CARD FOUND, hold action button, SAVE IPSM,GSM,WINCE and BOOTLOADER, brilliant! Now i decided to have a quick look at it in HEX Workshop V3.11 from BreakPoint Software, what a great hex editor! Anyways i noticed hex workshop allows me to open a disk drive and dump the image to a bin file, it also allows me to restore this bin file back to the disk, no idea what this could be used for! The file weighs in at 61 mb. Anyways i opened this bin file and looked through, its all good, it seems to have backedup my contacts and the registry (brilliant just what i wanted) so i was wondering, will it preserve my cert unlocked state if i flash it back, anyone in the know? DJ Hope
Guest Gorskar Posted January 21, 2003 Report Posted January 21, 2003 Hm I wonder if it is possible, when the update comes through to modify the web distributed version with the unlocked version of the xml files. If it was possible then you'd have the best of both worlds, however I'm ignorant re these sorts of things so Its probably a stupid thing to say.
Guest Arisme Posted January 21, 2003 Report Posted January 21, 2003 if they haven't changed the registry checksum algorithm between both kernel versions, yes (but that'd be plain stupid, then probably no :wink:)
Guest DJHope Posted January 21, 2003 Report Posted January 21, 2003 You see the thing is i dont think if you restore the backup from you memory card it does a hard reset, i think it just puts it back to EXACTLY the way it was at the time you backed it up, in which case it would keep the cert unlocked, thats why my registry and contacts is stored on their, because the registry is stored in IPSM . I havnt tried this (restoring the backup) so i wouldnt know, i just wondered if someone had? Also something else of intrest that florin also brought up, the files system is QFS Hilter, now i know QFS is a sun microsytems file system thus i doubt their is any connection, QFS = Quick File System, oh well couldnt figure out anything else! Gorskar: Thats not such a stupid idea! Some people managed to get hold of the update installation files when they were released in switzerland maybe we could do the same when the update comes here and remove cert BEFORE installing the update. But we shall see......... Oh and i almost forgot here's the disclamer: IF YOU BACKUP YOUR DATA TO A MEMORY CARD AND REFLASH IT, ANY MODFICATIONS YOU MAKE TO THE BACKUP (HEX EDIT ETC) WILL ALMOST CERTAINLY DAMAGE YOUR PHONE (thanks florin). YOU *SHOULD* BE OKAY IF YOU *DONT* MODIFY THE BACKUP AND THEN REFLASH BUT THEN YOU ARE PLAYING WITH THE ROM RANDOM SPACE FREQUENCIES MIGHT KILL THE PROCESS ;) I HAVNT TRIED THIS HENCE THE QUESTIONS! YOU HAVE BEEN WARNED :twisted: DJ Hope
Guest DJHope Posted January 21, 2003 Report Posted January 21, 2003 Having said all that microsoft indicate that they do this all the time heres a quote from the microsoft.public.smartphone froum Subject: RE: Device Rebuilds In The Field From: Neil Enns [MS] "Round Microsoft we use MMC cards to re-populate devices with configuration setings and applications all the time." DJ Hope
Guest Monolithix [MVP] Posted January 21, 2003 Report Posted January 21, 2003 Sounds about right, if you want to test applications on phones acertain states of development it would be an arse to reset them and configure back to "normal" over and over.
Guest HelloDave Posted January 21, 2003 Report Posted January 21, 2003 Now i decided to have a quick look at it in HEX Workshop V3.11 from BreakPoint Software Is HEX Workshop free? I'm looking for a free hex editor that will let me read an SPV ROM dump from a card reader into a file on my PC so I can free up my spare MMC. I tried Win Hex but it only lets you save small files in the trial version and I'm not paying $40 just to backup my ROMs! Windows 2000 DiskProbe lets you view the ROM dumps, interestingly, but only by individual 4096 byte sector, and it won't save anything!
Guest yzbob Posted January 22, 2003 Report Posted January 22, 2003 would it be possible for someone to post a newbie's guide to backing up your rom so that we can all have the option to revert back to our old "app unlocked " phone should we update and find it is now locked again. im reading about hex editors and stuff on the post that touch on this subject but dont know what to do? thankx
Guest madu Posted January 22, 2003 Report Posted January 22, 2003 yzbob, as far as i understood from other posts if it is updated, then ROM is updated too and cannot be (at least from a memcard) restored to a previous state. so if i understand correctly there will be no easy way of reverting to your current OS after an O Update. please correct me if i'm wrong :?
Guest DJHope Posted January 22, 2003 Report Posted January 22, 2003 Thats not quite true, it backs up the bootloader, wince, ipsm and GSM effectively backing up everything INCLUDING the rom , http://xda-developers.com confirms this. How else do you think MS update to an under development rom which dosnt work correctly and get their spvs back to wokring order? They use MMC cards of course ;) Their is one area that nothing can touch (excect connection via serial) and that contains the unlock code ! DJ Hope
Guest Monolithix [MVP] Posted January 22, 2003 Report Posted January 22, 2003 I would imagine the phone would stay de-certified, you aren't re-provisioning the provxml files. You going to try it now? :)I would imagine the phone would stay de-certified, you aren't re-provisioning the provxml files. You going to try it now? ;)
Guest neilg Posted January 22, 2003 Report Posted January 22, 2003 anyone have any luck with using this method as a quick and easy way to repeat de-certification. Unfortunatly I have to reboot my phone so much it is becoming a pain to apply the patch. I am also incredibly lazy so if it works can someone post the MMC/SD card image so I can just rob it :?: :!:
Guest DJHope Posted January 22, 2003 Report Posted January 22, 2003 Not likely mate it stored everything, including all my personal data and contacts infomation, passwords THE LOT, this isnt a half-arsed backup! So it appears that it will restore my SPV exactly the way it was when i backedup nice, now am i gonna try it and reload it!?!! The only problem with this is i like my SPV as it is maybe if something goes wrong i will have a reason to!!!! What it backs-up *ALMOST* EVERYTHING Example's Contacts/passwords/registry (EVERYTHING IN IPSM), BOOTLOADER AND ROM, WINCE, GSM (RADIO PART) What it dosnt backup, unlock codes and secret stuff in the ROM. How it works: 1- Start up the SPV in bootloader mode WITH at least a 64mb mmc card inserted which you dont mind loosing the data on (Switch off, Switch on Holding Record Button, Hold Down Action Key When Requested) 2- Goto SAVE ALL (BOOTLOADER+GSM+WINCE+IPSM) 3- When finished (this takes a long time its writing 61mb's of info here). goto end (press left twice), and the phone will reset at this point take out the MMC/SD card otherwise when it gets into windows it will ask you format the card (we dont want it to!) Optional 4-Open the memory card in a hex editor such as breakpoint softwares HEX Workshop. Optional 5-Tell it to save to a file Optional 6-When saved you should have a nice new .bin file containing your rom. TO RESTORE THE BACKUP Optional 1-Open the .bin file you created in Hex Workshop and restore it to the card. 2-Start up the SPV in bootloader mode WITH the 64mb mmc card you created (Switch off, Switch on Holding Record Button, DONT HOLD THE ACTION KEY THIS TIME). 3-It *should* (assuming you did this correctly) come up with: C a r d F o u n d BOOTLOADER IPSM WINCE GSM Press any key to restore. That should restore the backup, i havnt had reason to restore mine yet so ive no idea if it works, IT WILL REFLASH BACK THE ROM, so their is a risk it will die (as i said before you gotta hate those random space frequencies). If you f*ck with the backup you will destory your phone, no if's or but's YOU WILL DESTORY YOUR PHONE! CHEERS PEOPLE DJ HOPE
Guest Precognisant Posted January 22, 2003 Report Posted January 22, 2003 Worked a treat backup / restore from SD. Even tried editing some files with breakpoint. Would not like to push things too far in that direction though!
Guest DJHope Posted January 22, 2003 Report Posted January 22, 2003 Thanks for trying brilliant, now i can have a decient backup and i never have todo a bloody hard reset again! Did it keep all your settings and cert unlocked? DJ Hope
Guest Monolithix [MVP] Posted January 22, 2003 Report Posted January 22, 2003 Heheh sorted then, back up every week and any updates Orange provide will be surmountable. Assuming they don't edit the "secret" part of the ROM, or the bootloader "restore" option. Can this be done remotely?
Guest DJHope Posted January 22, 2003 Report Posted January 22, 2003 Depends how you mean remotely i *BELIEVE* it would be possible to talk to the bootloader via a serial cable but as yet not one has tried it, as for remotely via activesync or such method, most definately not this is something which is HTC's baby and HTC's alone, however i imagine microsoft have some way of reading the backup's file system which we dont ;) DJ Hope
Guest Monolithix [MVP] Posted January 22, 2003 Report Posted January 22, 2003 So a backup pre-update can be got round by MS, but is probably too much hasstle for say, Orange ;)
Guest DJHope Posted January 22, 2003 Report Posted January 22, 2003 Yeh but i bet 64mb mmc cards are cheep as chips for companies like microsoft and orange, they probably get passed around like floppys back in the day! Also as fars as i can tell orange and microsoft have a special version of "Orange Update" which is able to recieve pre-release updates, someone from MS Reading said that they all got smartphones and are being used as guinea pigs DJ Hope
Guest Monolithix [MVP] Posted January 22, 2003 Report Posted January 22, 2003 Heheh, "and we aren't?"
Guest madu Posted January 23, 2003 Report Posted January 23, 2003 DJ Hope, florin_m has managed to connect via serial and read that part of ROM (for sure!), and I would think the mobilelocksmiths or whatever the site was called have managed that too since they unlock SPVs.. PS: Some great posting from you recently :wink:
Guest DJHope Posted January 23, 2003 Report Posted January 23, 2003 Flattery will get you everywere hehe, thanks madukrainian, i wasnt sure if florin_m had done the serial trick i think it was kinda obvious that it'd work, although HTC did try to remove backing up things to the mmc card on the xda makes me wonder why they didnt on smartphone, but then i supose they could in a future update. For now though its an excelent way of backing up your phone for those who are willing to try it id prefer to do this over a hard reset anyday of the week! ;) DJ Hopre
