For Clarification Purposes Only-NaNdRoId - G1 General

-------due to the brick phones-------(and im not talking nokia)
I have started this thread to get some clarification on Nandroid back ups. Now i know there is already a thread with step by step instructions in the sticky's. But with all these G1 ones getting bricked due to the new spl incompatibility with the old radio is it safe to use. I ask this only because one of the steps is to have a recovery.img and the only recovery image i can find is for jf1.43 and one other. But none for the adp 1.5 builds. I am worried that if i were to flash a old recovery image, and it down grades my radio i may get bricked. I'm not really sure if that's how it works (if not please correct) and thats why i want to recovery image from the new builds ( i am using Dudes Cupcake 1.1)
Do they exist and if they do and i just haven't search hard enough please tell me. Or is the recovery image what i create when i do the back up. I ask all these perceivable noob questions because i really like my G1 and would hate to brick it.....
Please post some useful Replies... I think this thread could be potentially useful

Doing a nandroid backup creates a boot.img, data.img, and system.img of your phone. Flashing those three, restores your phone exactly as it was when you created the backup. As long as you do a backup of your system when it's stable, then it doesn't matter what you do to your phone. As long as you can get into fastboot, then it can be fixed in less than 5 minutes.
Dunno if that was the answer you were lookin for, but that's how I understand it. And it works....I did a nand backup of my Dude build just yesterday, and flashed over to haykuro's 6.0 to check it out...test drive it. I didn't like it, so I flashed the nandroid backup, and was back up and running in minutes.
You mentioned recovery.img....I don't know what that is or what you do with it.
Assuming you have fastboot setup, just do the steps in this post and you're golden-

the recovery.img is what the phone boots in recovery mode... the recovery.img that your referring to allows you to create NAnd backups easily with NANDroid... the recovery img is totally independent from your SPL (bootloader), Radio, and Firmware

Right on, thanks for that. Knowledge is power.
So the op says that he found the JF1.43 recover.img....That's the one we all have and the one he needs, right?

yep, they're all the same
All the recent ROMs EXCEPT for the official HTC ADP use the same recovery.img found in the previous JF ROMs (1.42, etc.). You can safely reflash the recovery image from fastboot without touching the radio, the SPL or even data, boot or system if you want and it won't hurt anything.

remember when you orig rooted your phone and the recovery mode didnt have the fractal background and you had to press alt+l to show the text? thats the OLD recovery img, the fractal bkgrnd (v1.43) one is the new one, and so far the latest "cooked" recovery.img

Like i said im kinda noobish. So after i downloaded the drivers, and the sdk for 1.5 i still need to download fastboot (to my pc) as well.

Great post. +1

correct...
the fastboot.exe is how your PC will interface with the FASTBOOT mode in the SPL
if you didnt have it DL'ed when you tried to fastboot, your computer would kickback that fastboot isnt a valid command or the like (depending on os)

so im reading all these tutorials, and im getting confused a little... to use fast boot through adb does my phone need to be at the boot loader (skateDroids) or are there commands that i would need to enter in order to get there....
I appriciate every answer i am trying to learn as much as i can. This has really spark a interest in my life and i really enjoy it.

fastboot is not part of adb, and yes your phone needs to be in bootloader to FASTBOOT, after entering bootloader plug in the usb cable and press the back button, your phone should read FASTBOOT rather than serial0
adb works almost anywhere (after splash1/g1 logo) except bootloader...
for reference ADB stands for Android Debug Bridge

I am still slightly confused how do i create a nandroid back up, i am using dudes cupcake 1.1. Is it the same as JF's alt-b

Yep. Boot your phone with home+power, then Alt+B. It'll create a folder on your sdcard called nandroid. All the .img files will be in there.

i dont think i have the right recovery image though do i just download the zip file. and do the whole rename to update.zip and install alt-s.
I only ask because i opened the file and found a recovery.img which made me ponder.

thats the Nand dump of your recovery partition... you figured it out...
if you made the backup you have the right recovery img.... the old one doesnt have it...

~edit~
I see I misunderstood the question. Duh

and when i booted in recovery mode i dont have the option alt-b. so i must have the old recovery image.
so now i need to (already have) download the recovery image zip file from jfs blog, rename it update.zip and flash it....right????

This is what your recovery mode will look like after you update it-

I can't answer your question about how to update to it though. Mine's been this way since waaay back when I flashed JF's RC33.

yea, thanks bro. mine definitely does not look like that. but now i need to know for sure how to update it.

How to restore from your backup file
1. Download one of the above signed SPL updates and rename it to update.zip
2. Copy update.zip to the root of your SD-card
3. Copy the Nandroid backup files data.img, system.img, and boot.img from your SD card to the folder C:\Android.
4. booting your Magic into recovery model
5. select [Alt + S] – Apply sdcard:update.zip
6. select [Home + Back] – reboot system now
7. After reboot it will update upgrade/downgrade your SPL version, then power off your Magic again
8. Push “Back” + “Power” to HBOOT model
9. double check your SPL version is upgrate/downgrate
10. Plug the USB cord back into your phone. The screen on your phone should say fastboot.
12. Press start, go to run and type cmd (If you are on Vista just type cmd in the search box and hit enter). The command prompt will pop up.
13. Type cd C:\android

12. After reboot your Magic, it need about 2-5 min to restore
13. then a band new original Android 1.5 is restored
Yes i have tried that, The problem is the boot.img. I cant flash it! Nandroid restore fails due to boot.img (cannot be flushed!) Thanks for the speed yresponse but still no joy

Did you follow ALL steps while rooting your 32B?
I'm almost 100% sure that you are using your 32B with a 32A radio and rom, right? Complete the rooting by following the "Revert to 32B Radio and ROM" exactly to the letter in this thread. Do not try to do something else or you'll brick it.
i followed all steps apart from using the gold card as i couldnt make one and reverted back to 32B using your steps. I also did it all again but using flashrec.apk?
try this flashrec.
worked for my 32A
http://zenthought.org/content/project/flashrec
Done the flashrec thing, Quite a few times now i have a feeling as it was repaired by htc and sent back they have made it so the boot.img cannot be written in any way, If i use a friends nandbackup of hero it fails (not that it says so) and just keeps on the splash screen untill the phone becomes so hot it switches off! Giving up on this, Gone back to standard (rooted) rom and will await the sense update (fingers crossed)
Stil lthe same problem...although it WILL let me flash sapphire boot just not a modified boot see here....
First flashed boot.img is the google ion boot off of the htc site
Second is the tattoo boot.img modified for the sapphire. Any ideas?
Anyone know where i can get the Google Ion hboot from? just wanna try one more thing before i give up!
Have you posted this in Dream Q&A? That forum is way more active and there is alot more knowlege on things like this. Maybe send David1077 a PM. I feel bad because I have looked at your post for quite a few weeks now with little help. Good luck
i would but am afraid of a ban for posting in wrong forums,ive already done that lots!
somprogress
seems lile i can fastboot boot the img but it just loops at the boot screen?as i say donut roms work fine but ANY sense ui fail at line 92

so what is the hboot?
what are you excactly asking for
The hboot is the spl, im asking for the dev one as its naturally enabled for fastboot therefore im trying to trick my phone to make it think its the dev phone (Google ion) hopefully bypassing the "REMOTE: image update error'' when writing boot.img
have you tried the one i'm on Engineering SPL 1.33.2004 by Crios
Engineering SPL 1.33.2004 by Crios is actually a hex-edit of SPL 1.33.2005 to fool updates.

When you tried the EUUS did you follow the flowchart in the second post of this thread? http://forum.xda-developers.com/showthread.php?t=1816560
I just ran a EUUS fine following the flowchart - But had a result similar to yours when I didn't unzip the EXE and fill in the CPUID.txt file.
I'm in the same situation, no way to get the v8 UNL BL, stops at stage 2 (BT's apxflashtool) and "3/4 recovery" with AfterOTA TOOL.
I shall try the EUUS flashing (will delete your internal memory), but now I'm very busy so I renounced..
The EUSS file flashing should help

Couple of ideas to try...
Make sure that when that screen comes up there is not a second window it spawned hiding behind it... For me when it got to that screen I saw another window pop, and it was hidden behind the main, the popup window walks you thru the next steps of setting APX mode, plug in cable, hit ok......
Another thing to try is Right click the PBJ20upgrade.exe and choose "Run as Administrator"
Finally download a new copy... when you unzip it you should end up with Several files and then two folders /Image and /usbpcdriver. The /Image folder has all the img files it needs to install. In the root there is a file called version.cfg that when I view inside it seems to have the info that the program uses to tell what version it is going to install... Hazzard a guess that if that file is missing it might not know what its going to install.

[Q] [Fastboot] Can't flash Stock ROM

Hello there!
I have a Nexus 7 Device, I rooted it using a toolkit, everything was working great, then I messed up a little and I need to restore it using a Factory Image (a.k.a Stock ROM)...
The problem is, when I try to flash the .zip, it gives me the following error:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
According to some tutorials, you type the following commands to flash a ROM:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot -w update ROM.zip
Click to expand...
Click to collapse
Because I'm afraid of something going wrong, I didn't erased any partition, so if for some reason the flashing procedure stops, I have the old data/partitions working because I didn't erased any, I just used the following command:
fastboot -w update ROM.zip
Click to expand...
Click to collapse
So, the questions are:
Do I need to erase the partitions first before trying to flash the Stock ROM?
Should I try flash each .img separately?
Additional Information:
Android is working, I'm able to boot with success.
Bootloader unlocked.
I didn't flashed any custom Bootloader/Recovery/ROM, everything is from Factory/Stock.
I have tested flashing the ROM under Windows and Linux (Ubuntu), it gives me the exact error.
The .zip I'm using isn't corrupted. (And it's directly from developers.google.com)
If flashing without erasing the partitions worked, I would erase them (To delete ALL data/trash) and flash it again...
P.S: First post!
I'm pretty sure the script erases those anyway... You could open it up and check though. Don't worry about the .sig files; that's normal. Check inside the .zip to make sure the system.img is actually in there. If it is, then extract it and try flashing it by itself.
In fact, if you just were trying to fix something you messed up, all you need is the system image anyway.

Hello!
Thanks for the answer, I tried to flash system.img and it worked, fastboot automatically erases the system partition.
I have now a clean system, thanks!
For other people with the same problem as me:
1 - Enter Fastboot Mode
2 - Extract system.img
3 - Run "fastboot flash system system.img"
4 - Enter Recovery Mode and do a "Factory Reset" (Optional, I guess)
5 - Enjoy!

I wouldn't jump to that conclusion quite so readily.
It merely overwrote whatever contents were already there.
More or less the same result though, excepting some possibly inconsequential trash in the partition slack space.

I believe fastboot really erased the partition, there's no "SuperSU" anymore and I have attached a screenshot of fastboot erasing the partition.
Cheers!
I wouldn't have believed it until I saw the picture... and now I believe! My bad!
I could swear I've done the same thing on other devices for a couple years now without the implicit erase happening. I wonder if it is a fastboot version difference.
If you don't mind me asking, what version of fastboot is that?

Android SDK Manager says "Rev. 16.0.1" (Platform-tools), maybe fastboot erased the partition first because I used "fastboot flash" instead of "fastboot update"...
A little off-topic:
I tried to root manually my Nexus and it's really easy, I might make an updated tutorial soon on how to root it manually
Have a good day!
Edit: I tried to flash TWRP (Recovery) and it didn't erased the partition first.

Do you have adb/fastboot drivers installed? If not: https://forum.xda-developers.com/showthread.php?t=2317790
When you have that installed, boot into TWRP then tap on the Reboot button and then on the Bootloader button.
Plug in USB and open a command prompt, type the following command:
fastboot oem get-build-number
Post the result here
i solved this issue just today, i didn't get lucky with stock rom kept boot looping. What i did is get fromfuture mate 9 custom rom, place the zip in twrp folder and install zip from there.
The update.zip wouldn't install this way. At least my phone is working now.
Thanks
Edit: I also tried to flash update.app image components after extraction, using fastboot. It didn't work, I don't recommend this method.
The custom rom is life saving.

Ah, then you're on Nougat.
The reason I asked about fastboot was to find out what build/fw you were on, then go from there to install stock firmware.
You could update to Oreo using: https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108
hey thanks!
The reason why im statisfied with this is that when flashing stock rom, it worked the first time (no bootloop), but the camera was not working, neither developper mode. Thats why i wiped, reflashed and got stuck in bootloop, no idea why. Also i could only flash a few of the images in update.app, very few. So it was not ideal, other images would yield an error in fastboot when flashing (command failed), i read online and figured this is perhaps due to a bad unlocking in the bootloader (if i understood correctly) at this point i felt that i could no longer process and learn info in android world, after all it was only one day that i'm into android and i felt tired, so i took the ladt chancd and decided to try the custom rom, im now satisfied with results, but many question marks are still in my head.

It's because you can't flash everything from fastboot with just phone unlocked.
You can flash: System, vendor, boot (ramdisk and kernel for oreo), recovery (recovery_ramdisk, recovery_vendor, recovery_vbmeta for oreo), cache, userdata. (I think those are it)
Flashing anything else requires you to unlock bootloader, but it needs a special code which none of us normal people have. :/

Can you give a hand, please ?
I unlocked the bootloader and flashed the recovery, the system booted successfully.
I tried to flash a ROM after that, it showed errors and didn't complete the flashing. since that time the phone has bootloop.
Unlocked bootloader and FRP
fastboot oem get-build-number : MHA-L29 8.0.0.374(C185)
I can access the TWRP recovery and erecovery and bootloader&fastboot
what I have already tried :
1-Fastboot flash ramdisk and kernel .
2-Tried to flash the stock firmware via TWRP.
3-Tried HurUpdater0.3
4- Extract update.app & HOWTA
5-Flash ramdisk and kernel from inside TWRP

Make sure you have unlocked the bootloader AND unlocked critical partitions, then flash the latest factory image found on essentials support page. DO NOT flash TWRP or anything like that.

How do I unlock critical partitions? Also I have already flashed TWRP. If I try to push the factory image without TWRP it tells me not enough space.
I suspect you need to change the slot that's loading... I had a similar thing recently. .. Try going into fastboot and typing "fastboot --set-active=slot" where slot is "a" or "b", depending on where you flashed TWRP (you need to load the opposite slot).
If that doesn't work, flash the original boot file in fastboot and keep everything crossed...!

My slot b has been fleshed with TWRP and a with the original os. I still can’t get it to boot. Is there anyways that I can just flash everything back to factory setting? I don’t care about personal data. I even tried flashing both slots with the os and still no luck
flash OTA via adb sideload , it will fix your issue
Just do the fastboot flashall from the Essential download page and start over. I flashed the october update the other day and my phone has been running so much better since then.

Instructions are on the Essential website where you can grab the downloads. Basically download the fastboot image, unzip it and run the flashall script inside the unzip. Easier if your fastboot path is setup properly. It will flash stock to both slots and away you go.
You NEED to unlock critical partitions to flash all of them.

You can see it flash both slots and all the images? Should be able to get a screen grab of it.
If your environment is setup correctly and you say it flashes I can't be of much help unfortunately.
