Hi there,
After rather stupidly changing my dpi settings to play a game on my prime, I was presented with a boot loop. After reading around I discovered that it was possible to restore by a Micro SD card. Unfortunately the slot in my device is jammed with an existing card and I can't remove it, is there any other way to restore the device to working order?
Additional information:
The device was rooted by a friend, and unfortunately I'm not very knowledgeable when it comes to using the Android SDK, is there any way of pushing a fresh build.prop to the device?
Thanks in advance, any help is appreciated.

You arent unlocked are you?
Try this
Hold your power button and Volume down key during power up, you should see some white text appear. Release both buttons and press volume down again. You should get three options. choose the one to the very left "Factory Reset"

It won't help, build.prop is in /system.
The only solution is adb, if debug option is on evidently.

Good call.
I would like to give credit to everyone who has worked on the android roms, and other guides. I have taken some of the info for this guide from the WIKI
It seemed we were due for a friendly how to guide on how to load a NAND rom on a RHOD device. I decided to write a step by step guide to help people out. This guide does provide a very basic ADB setup, but it is just enough to get you up and running. If you want to do advanced things you should get the full ADB, and learn more about it.
This guide is written for a RHOD400, Android GBX0*+3.4.26 rom, and a Win7 pc, but should be almost identical for the rest of the RHOD family, other versions of Windows, and most other roms.
It is assumed that you have unlocked your phone for custom rom loading in the past at some point. This is not the same as unlocking the sim card. This is 100% required. Please read here and/or here, and/or here if you need help with unlocking your phone.
This guide assumes that you know what a command prompt is, how to load windows drivers for a device, and can open zip files. If these things are not within your skill sets I would recommend that you find someone who understands these things to assist you.
Things you need.
1. A RHOD phone.
2. A micro SD card that is at least 512mb in size.
Tip: I suggest a sd card that is less than 4gb in size. There tends to be less compatibility issues with non SDHC cards. SDHC cards usually work, but if you have trouble this is a good thing to change. The SD card does have to be less than 64gb in size as the phone can not read cards larger than 32gb.
3. A usb based micro sd card reader. A usb based card reader is need to be compatible with the HP format tool. Some built in ones are usb based others are not. If you have one, you can try it and see if it works. It is not recommended to use your phone's sd card reader for prep work.
4. A usb cable that is known to work. Test it in WM first. On rare occasion I have seen cables that did work with WM and not Android. If you have issues, this is also something good to swap out during trouble shooting.
5. A windows based pc. *DO NOT USE USB 3.0 PORTS* Many reports about have come in about them causing issues.
The procedure.
1. Back up anything you want to keep from your phone. Everything on the phone will be wiped during this process.
2. Put the micro sd card into your USB card reader and format with the HP format tool. It needs to be a full fat32 format. Windows format is known to have issues on occasion, and this step is a work around for that problem. It is not 100% required, but if you have trouble it is 100% required during trouble shooting.
3. While this is formatting you can download the recovery (recovery_cwr_6.0.1.3.img) ***It has been found that the 6.0.1.3 recovery does not make backups correctly, resulting in md5 errors. You may use it if you are not planning on using the backup feature, or the older one by acl works fine. You can rename it to use the included scripts if you wish.***, rom (GBX0*+3.4.26 Full) , the boot loader, the needed usb android drivers, and the adb files.Gapps is optional.
4. Make sure your battery is at least 50% charged. I recommend a 100% charge. A dead battery in the middle of flashing can brick your phone.
5. Copy the RHODIMG.NBH, rom (GBX0*+3.4.26 Full), and the gapps (optional) files to the sd card and put it in your phone with the phone turned off.
6. Press the hold down the volume down button while pressing the power button. This will bring up the tri colored screen. It will then automatically go to the white rom update screen.
7. Follow the directions (press the power button on the RHOD400) to start the update. This should take less than 1min.
Troubleshooting tip:
If the phone sits at loading 0%, and never moves after 10 min you may not have unlocked your phone or there is an issue with your RHODIMG file. Verify that you have unlocked your phone (you can try loading a WM custom rom), format the SD card, re-download the RHODIMG file, and try again. Also try another SD card and SD card reader.
8. If the phone reboots automatically, that is fine. Otherwise when the phone says Update Success you can pull the battery to shut it off.
9. Turn the phone back on. You should see a blue miniPooploader screen with a lot of white text scrolling for a moment. When it gets done, pull the battery to shut it off. Then replace the battery (it should still be off)
10. Connect the usb cable between the phone and the PC, and turn the phone on. The PC should see the device, and may or may not assign drivers to it.
11. Install the USB/fastboot driver for the phone. On Win 7 the phone showed initially as android device under other folder in the device manager. After the driver is installed it should be called My HTC.
12. Open the ADB Tools zip file, and put the platform-tools folder on c:\
13. Open a command prompt and go to c:\platform-tools\.
Once there type:
Code:
fastboot devices
You should get a response similar to this:
C:\platform-tools>fastboot devices
HT04TM300704 fastboot
If this is not working stop now and troubleshoot.
14. Now to wipe the phone in prep for loading (or reloading) the android rom.
There is a wipe.bat file I have included. You may run it, or you may type the following commands.
Code:
Fastboot erase recovery
Fastboot erase boot
Fastboot erase misc
Fastboot erase system
Fastboot erase userdata
Fastboot erase cache
15. Place the recovery (recovery_cwr_6.0.1.3.img) file into c:\platform-tools.
16. Now load the recovery image. If it is named recovery_cwr_6.0.1.3.img you may use the reload_recovery.bat or type:
Code:
fastboot flash recovery recovery_cwr_6.0.1.3.img
to load the recovery image then
Code:
fastboot boot recovery_cwr_6.0.1.3.img
to boot the recovery image.
17. Install the rom.
Using the volume keys highlight 'Install zip from sdcard' then press the call button to select it.
Highlight 'choose zip from sdcard' and press the call button to select it.
Highlight the rom file (GBX_3.4.26_Full.zip) and press the call button to select it.
Highlight yes and press the call button to select it.
The rom will now install. This will take a few minutes.
18. (optional) Install Gapps.
Using the volume keys highlight 'Install zip from sdcard' then press the call button to select it.
Highlight 'choose zip from sdcard' and press the call button to select it.
Highlight the gapps file (probably gapps-gb-20110828-signed.zip) and press the call button to select it.
Highlight yes and press the call button to select it.
Gapps will now install. This will take a few minutes.
19. Press the back arrow, and select reboot system now.
The phone should reboot into the Android rom now. It will take about 10min the first time. If you have waited more than 30 something has gone wrong. You should troubleshoot and try again.
At this point you have the basics all in place, and can start using your phone.
If you want to do basic ADB tasks (along the lines of installing apps remotely/side loading or pushing/pulling files) you will need to install the adb windows driver.
20. Press the thanks button if you liked this guide.
P.S.
If you have issues getting adb to work later, download and use USBDeview.exe to remove the HTC driver entries and then install pdanet for android to get the correct adb drivers installed.

Well if you have not listed all your trouble shooting steps, you will not get help from anyone. Our physic abilities are lacking these days.
Also posting specific questions in the thread about the rom you are trying to install will have a higher chance of getting useful feedback.

Well if you have done all necessary things, then your phone must not be compabtiable.
Maybe if you provided a list of your troubleshooting steps we might be of more help... Otherwise we have no choice, but to bow to your knowlage of having done all necessary things.

Thank you WizardKnight for replying me.
This is the steps i use to do.
1. I use RhodiumWUnlocker to unlock my rhod500 , to get any rom loaded with it
2. I copy RHODIMG.NBH, GBX_3.4.24_Full, recovery_cwr_6.0.1.3 all to my 4gb SDard
3. Vol- + PWR and phone turns to the tri color screen, then the phone started to load the image files
4. I press PWR butt to start the update, within a couple of seconds the phone update successfully
I press resest button for the phone to boot up to see if it will go to the fast boot screen.
But i was unlucky always the phone restart itself within some seconds.
This is my Prb

Sounds like you just need to flash CWM... the CWM recovery image doesn't go on your SD card, you flash that from your computer using the "fastboot flash" command...
You can also try "fastboot boot <recovery.img>" - w/o the < >. Remember, this is done on your computer. That's why you need the fastboot drivers...

You Mean This .
9. Turn the phone back on. You should see a blue miniPooploader screen with a lot of white text scrolling for a moment. When it gets done, pull the battery to shut it off. Then replace the battery (it should still be off)
My Phone doesn't bring this window

I have a rhod400. I have been messing with OMGB as my daily phone OS since July 2012 and just installed this one about a week ago.
I have two questions/issues
1) Every time I try to reboot, it freezes. When I try to power off, it sometimes freezes, but usually reboots.
2) I can't seem to make persistent changes to the hosts file. After every reboot, it's set to the same old generic "127.0.0.1 localhost"
During boot, does the OS unpack a .img or something with the hosts file packed inside it? If so, where is it?
Thanks, guys. Other than these 2 issues, this flavor of android for rhodium is pretty solid. i like it.

Please put rom specific questions in that rom's thread.
If you are running a newer than.27 kernel the reboot and power off functions do not work properly in any rom.
I believe that the host file is overwritten by the ram disk/boot.img on boot every time. Any changes will not stick.
There is a chance these issues may be fixed on the next release of GBX, but no promises.

This isn't enough information to help you.
If you're not going to provide detailed information on what is happening, no one will be able to help you.
Perhaps NAND is not for your device. Flash back to WinMo.

Can you still get into Recovery mode (hold down Power and Volume Down at boot)? What about Windows mode?

You can access to boot menu with Power&Volume+
Also, if you plug an USB keyboard and press esc at boot, you can access the BIOS, it also have a boot menu.
I have tried many times with many different builds (this latest time with the 08-30 build), but I can't get Remix OS for PC to boot on my tablet (Teclast X16 Power, Intel z8700).
The problem is that after the install process, the Remix OS boot selection does not show up in the Windows 10 boot menu.
I have attached a zip file that has a screenshot of my boot configuration (from EasyUEFI).
Suggestions?
Easy UEFI doesn't show you the boot menu. That's just the boot order - if you want the RemixOS entry to load move it to the top [top button in the middle]
OK, so how do I create a boot menu entry (in the Windows 10 boot selection menu) on an UEFI based tablet?

I did some more experimentation....
If I go into the UEFI BIOS and manually select Remix OS in the BIOS boot selection menu, it does start the Remix OS boot process.
I did run into 2 problems:
1> It brings up a boot selection menu that does not respond to touch screen or anything like that, so I had to connect a ketboard to my tablet just to boot it. It would be very helpfull of that boot menu either detected touchscreen into, or perhaps also support the volume up/down buttons and the power button for menu selection (the way old Android phones did). Or better yet, just have an entry in the Windows 10 touchscreen boot menu, the way that PCs with BCD based boot does.
2> The Remix OS boot process only mad it as far as the following prompt " ANDROID [email protected]_x64:/0# ". At that point it seemed frozen, and the system needed to be rebooted. I tried it a few times but couldn't get past that prompt, so I had to boot back to Windows 10.

EasyUEFI shows the same list that you see in the BIOS - so moving it up in that would make it default.
On 1> Best you can do is modify the grub.cfg to autoboot and add another Windows entry [maybe add a safe boot one] and see if you can get to Advanced settings ==> Use a device. If you wanted the volume keys you'd need either an updated BIOS with vol button support [probably not going to happen] or perhaps someone can compile a version of gummiboot to work.
On 2> Not sure how supported cherrytrail is: hopefully someone has some grub args you can try
