OK so hi guys,
after I tried, search, read tons of stuff, I finally decided to post a thread because I have no clue what else I could do.
I have have a lenovo tab4 8 plus / tb-8704x tablet by my hand and it only boots into the recovery menu like u hold volume down and power.
1. I don't know what happened to it before, I got it like it is.
2. If u plug in powe supply the red led blinks and u can only power it on by holding power for around 10 seconds, then the lenovo logo -> then recovery menu
3. Also If I hold down volume down and power it on it boots into the test app, to test if all stuff works.
4. In the test app I tested the volume buttons and recognized the up button had no response, so I took it apart and measured it. And if I press volume up then I get a good reading (peep). So the volume keys both are good.
5. The I tested flash a stock rom to test if that fixed the problem. I used TB_8704X_S001025_190606_ROW from the lenovo rescue program, but if I try to flash it inside the recovery menu over SD Card it only said wrong footer, error 21.
6. So i decided to use the qfil and the base stock rom TB-8704X_S000026_170707_ROW_QFIL. And after I always get sahara error messages if I use it only windows 10, I booted up an old win xp PC installed version .460 and the Qualcomm drivers, then hold down volume up plugged in USB, clicked the right Qualcomm com port and all went well first try no errors.
7. Then I unplugged the tablet, hold down power until it reboots but still nothing only recovery menu.
That's why I decided to post here, in hope someone can help, has new ideas or something else.
I hope all is good understandable.
//edit I uploaded to images, that's what I get if I boot f.e. the latest stock rom (named as factory_update.zip) from lenovo on an fat32 formatted sd card (exfat will give error and is not been able to mount)
Update:
I also managed to update to the latest rom from lenovo. Then it boots again in recovery mode but a different error.
For testing I've put the sd card with the same lasted update file inside. Then it starts the update process again. It starts install, tries to erase and then error and it boots again and then I'm in a boot loop until I remove the SD (because the image is named factory_update.zip so it's auto starts update process)
Pictures in attachment
Im pretty sure after all my testing, it's a hardware failure so, this thread can be closed.

Bricked IDEOS S7
If you have not already got your S7 back to working condition you may try the following. I faced similar situation(s) some time back.
Requirement: External sdcard formatted in FAT32 and with dload directory with firmware installed on the unit. Use Indonesian stock firmware Froyo 2.2.2. Search around and it is easy to find. Make sure one of the files is unlmt.cfg and not any other. No glitches and all modules work fine. Since I have been experimenting with different ROMs and some personal mods I have flashed so many times, got lost and started all over again.
It is not necessary to have a battery installed but the charger must be connected.
1. Press Back and Power button together to startup and release Power button after few seconds. You should see a white bar. Release Back button.
2. After a few sec disconnect power charger.
3. Reconnect the charger. Press power button. You will a stable IDEOS for few sec and flashing will start.
At times you may have to repeat more than once to get it going. The blinking should be slow. If suddenly flashing stops after few bars or blinking frequency jacks up disconnect and try again.
Best of luck.
Restoring of brick Huawei U8800.
All do at your own risk! I am not responsible for your machines!
Today I was able to magically (just wonderful, because it found the time at which there is a chance to run the update) to recovery from a brick Huawei U8800 (corrupted bootloader + recovery not run + in a pink screen not mounted hard drive + when trying to update the written Update failed! I spoke to a service center, they said the warranty is not the case and we must change the motherboard (the cost of 3-4 million BYR, new at the MTS salon cost 2.9 million BYR )
What and how I did:
1) To restore I'am using the firmware B162 Android.
2) Format the micro SD card that was clean (I was 8 gb, 2 class and be sure to FAT 32) and unpack "dload" folder and ".txt" file(with a strange name) from the downloaded archive to sdcard.
P.S. I say that not all flash drives can operate restore, I have like three went, normally only one.
3) Insert the micro SD into the phone and pull out the battery.
4) Hold down the Volume (+) and power up, hold and connect the phone via cable to your PC, your phone will be switched on and the logo appear, then turned off my phone (missing logo). So, when the logo will disappear (ie the phone will turn off) and immediately hold down the volume (-) the volume (+) and power up.Main that the updating process can start only one time after the logo was gone, if after a few times in a row press both the volume keys and power up, updating does not start, it is necessary to re-clamp the volume (+) and the power up, after the disappearance of the logo, both the volume and the power up of ... I have to go to the upgrade process if you wrote "Update failed!", try again (I went with 2 times).
5) After a successful update, the phone will reboot, on reboot he should loaded the standard blue recovery.
6) Turn off the phone from the computer, insert the battery, hold down the volume (-) the volume (+) and turn on, wait until you get a pink screen, release the button and connect it to your computer. You should see a new device and to define a disk drive with a folder "image". If we define - rejoice!) If not, then you need to install the driver on the internet enough to the driver, as well as the wood in my going to the Android SDK, not sure ...
7) Thus, we can assume the phone repaired) Download recovery 4.0.0.5 and unpack the archive and copy the file "recovery.img" to a folder "image" with the replacement. A man does not 4.0.0.5 recovery loaded, it is strange, but recovery 5.0.2.7 normally loaded
8.) Disconnect the phone from the computer, pull out / insert the battery and try to enter the recovery (volume (+) and power up).
9) If set, then everything is OK and can now be sewing. I still put 2.2 Geno v8.4 + software package from Google, but I recommend again read all instructions on the firmware, to avoid problems!
Good luck, hope that helped someone, he sat on the forums more than one day, but have not found a solution.
If someone has turned out, a sign of gratitude you can throw money on my phone +375297176005 (MTS, Belarus), would be very grateful
P.S.
Instructions is my and it's my first, that do not copy and paste, you can search the Internet. Do not judge strictly, if something is not designed ...
If there are people who helped, I think you can throw his hat in the description. My message is also present in our 4pda.
Hope springs eternal
Sorry for my english, I'm from Belarus and bad know it

Hello, I have a problem after changing recovery.img. Now after power on only error message: Image signature verify fail. Your boot/recovery image may have an incorrect signature. Please update your image to a signature official one. You can remove battery for power down.
When I get to pink screen - no disk appears in my PC. Please, what can I do now?

Just thought I would mention it, if you connect the pink screen to Ubuntu/Linux, it will most likely mount.
Just tried this recovery method on a bricked U8800. Didn't do anything at all. Must admit that it was bricked in a way that i didn't see anything at all on the screen. Neither did i notice anything in dmesg on a linux machine.

Hello.my huawei u8800pro v.2.3.5 brick after install official ice cream sandwich.I followed the procedure and now I have a new removable but I can't go to recovery mode!!can I install a new rom?
This is a painful message to write, but I am desparate. This should be so simple!
Have a U8800 standard (at least it says only "U8800" in settings/about phone.
What have I done:
- Upgraded some time ago to 2.3.5 Rev B522 from Huawei.
- Then rooted it with SuperOneClick.
- Installed ClockWorkMod from Play Store.
- Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.
- Turned off Fast boot under settings/applications
:: What worked/happened.
- Rooting went fine, ES file explorer and others get root-permissions ok.
- But got into CWMRecovery only via CWM program (Choosing "Reboot into recovery"). Never with the holding buttons vol+ and power-button during power-on.
Figured it was that locked bootloader on B522 that was the problem.
What I did:
- Followed the instructions in http://forum.xda-developers.com/showthread.php?t=1457490 (Get your pink screen back).
- In CWM Recovery flashed "update-B518-bootloader.zip".
- Got "ok installed or something to that effect" from CWM Recovery.
:: What worked/happened.
- Still could not get into CWMRecovery via button-holding. Tried reflashing the B518 bootloader a few times, but just no difference.
Read somewhere that each Huawei firmware-release comes with it's own bootloader, so lets try to install Huawei B518.
- Only place I could find the image was here http://huaweiideosx5.blogspot.no/2012/03/u8800-b518-23-software.html
- U8800V100R001C00B518G001.zip
- Had to take out the external SD-card to get the /sdcard/dload directory on the internal SD-card.
-Seems to be important to have dload on the internal SD-card and not the external.
- Booting the phone with vol+, vol-, power did not start the downgrade, but was able to trigger it via settings/storage/software upgrade.
After downgrade to B518 (Checked version in settings/about phone):
- Deleted /sdcard/dload directory.
- Rooted with SuperOneClick
- Installed ClockWorkMod from play store again.
- Put CWM Recovery 5.5.0.4 into ./cust_backup/image again (think this was unecessary. I think it was already there but did it anyways)
- Turned off Fast boot under settings/applications.
:: What worked/happened.
- The phone is now in B518 software, but still can not get into CWM Recovery via keypressing at boot.
I hold the vol+ and power-buttons all the way to "desktop" so to say, but can not for the life of me get into CWM Recovery that way. Getting into CWM recovery 5.5.0.4 via instructing CWM application to boot into recovery works fine, though.
I am drooling at the thought of ICS Aurora, but I don't dare before I can reliably get into CWM Recovery via keypress.
Sorry if this is very stupid post, but I have tried so much.
Maybe the volume buttons are faulty? Turn off the phone and try this: hold down volume up; while holding press power button as long as the logo comes up. Release power button but continue holding volume up. If it did not work, try doing same with volume down.
Yeah, do what Blefish advised you but do it while the phone is off and charging. I have a kinda broken power key and with this 'trick' it boots faster and more reliable. Keep holding the 3 buttons until you see the recovery.
Sent from my U8800
Thank you both for trying to help me here!
Unfortunately I have had no luck with your suggestions.
Re: Broken keys.
Power and volume-buttons seems to work well when the phone is on. Also when I boot into recovery through the CWM program, navigate to advanced/key-test, the vol+, vol- and power button seems to work well there too.
On pressing the power-button, CWM-R reports Key: 116
On pressing the vol+-button, CWM-R reports Key: 115
On pressing the vol--button, CWM-R reports Key: 114
So I think the keys must be ok, right?
Blefish: I did what you suggested, as I understood it.
When the phone boots, there are three stages of logos.
1. A static logo of Huawei's red "fan?".
2. A short "comet" animation.
3. An animated logo of Huawei's "fan", where some highlight flashes from left to right over the fan.
I hold the power-button in until I see the first static logo, then let go of the power-button and hold the volume-key(s).
Is this the same stage in the boot-process that you were thinking of?
I have tried vol+, vol- and both vol+ and vol-, together with releasing the power-button at that point.
Have not had any success with that, and ended on the "desktop" each time.
AceDroidX: I tried your suggestion as well.
I did this:
1. Shut down the telephone
2. Plugged in the power.
3. A "fan"-logo appears which is replaced by an animated battery.
4. Upon seeing the animated battery, I tried the various key-hold variants.
- vol+ and power : Ended up at desktop.
- vol- and power : Ended up at desktop.
- vol+ and vol- and power : Ended up at desktop.
So not much success either.
I am out of ideas... Can it be that B522 bootloader that still lingers in there, not replaced by installing the B518 software?
Well, idk what else to suggest.. Maybe your problem is here?
Downloaded CWM Recovery 5.5.0.4 stable from xda and placed the file into the /.cust-backup/image folder via Remount.

I remember that when i mount my phone in linux, there was a partition with just the image folder. Some files like boot.img and recovery.img where there. Try to put the recovery image in there and see if it makes any difference.
I'd like see your versioninfo, can you upload a screenshot?
You can check mine from B528
AceDroidX: When I use Remount, I am able to mount that partition as read/write so that I can copy CWM's Recovery image in there. I think it is identical as mounting it up remotely, as you do. I am after all able to boot into CWM-Recovery, just not by key-pressing? I suppose I could boot into Linux and try to mount up the partitions as you do.
Hi kilroystyx: I can not figure out where to find a similar-looking page as the one you have in your picture.
I have the settings/about phone, if that is an older version of what you have there?

Based on the screenshots your installation is fine.
Just one last shoot based on what AceDroidX says, with phone off press Vol+ and hold then connect USB cable to PC or charger and stay holding Vol+ then wait...wait and what you see?
hi all,
i'm using some ics roms and it seems ics supports natively vol++power button to take screenshots but it doesnt work for me... do you know if there are some custom ics rom where it will work?
thank you
Wow.. It is hard to believe.. but I have actually ... eventually found a way to get into that CWM-Recovery every time.
It is a combination of your suggestions.
I have been doing variations, trying to figure something out and eventually there is a method.
What I must do, on this phone, in order to get into CWM-R is this:
1. If the charging cable is in, then unplug first.
2. Turn the phone off.
3. Take out the battery and put it back in.
- This makes a difference on my phone, at least. I am not able to get into CWM-R wihtout taking the battery out first.
4. Press and hold Vol+
5. With Vol+ being pressed continously, insert the charging-cable.
6. Wait for the Fan-animation to finish and the "battery-charging" animation to start.
7. When the battery-charging animation is running and the screen eventually goes black, keep holding the Vol+ button for some time.
- Sometimes it works to keep holding the Vol+ button for only a second or two. Sometimes I must hold it up to 30 seconds.
7. Press and hold the power-button in addition to the Vol+
8. Wait for CWM-Recovery to start.
Thank you very much for your help.
Now I think I can try for ICS!

What's your build number what version of supersu did you try to flash?
Shutdown your device, put your current build onto 'dload' folder in the sdcard and press the following key combo: POWER, VOL-UP & VOL-DOWN, it should enable automatic update process

Man, your phone is badly bricked. If you don't have at least access to fastboot, then you're screwed.
Good for me to I have the same problem. I was trying to get to stock ( I have made it several times), but the last time was a fail... The whole process of sending firmware was ok. then a reboot and brick.
Now the huawei screen and the short vibration appears and shutdown.
I was trying everything.
In device manager the phone is displayed as mobile devices \ volume f:\ (drive letter)
in connected devices the phone is detected as
hi6210sft
Phone is not detected in fastboot or ADB.
I met this problem yesterday(I hope the identical ). Because I have two booting animations, one from Vodafone, I guess I shutdown early during installation. It just froze. Then it didn't boot and stock recovery didn't help
My solution needs some recovery software like twrp. Press three buttons at the same time until twrp mode. Copy zip file for SuperSU to phone or sdcard, then flash it. After that my phone works again.
You mentioned that you cannot start recovery. Try more. After installing twrp, starting it is quite annoying. Sometimes it just doesn't start or stock recovery starts. An alternative way is to go to whatever mode, and try adb or fast boot to reboot to recovery. Pressing button requires techniques which j don't have
I can't enter TWRP non combination is working for me. Installing firmware using dload from sd card also.
okay if non of these worked you can try flashing the whole update.app file by fastboot..
tools you will need
1- download the official huawei firmware from the official site
2- download Huawei Update Extractor
3- download minimal adb and fastboot
check the unbricking chapter of this thread
Note: to get in fastboot make sure you connected your phone to computer and press the vol down and power down buttons.. if none of these worked your phone is hard bricked .-. .. try opening the phone and reconnecting the battery worked with someone
if you need any help just pm me or replay on this thread hope that help you
Ok thx. I have already opened the phone to reconnect the battery
And then I was trying the combinations;
Battery connected vol- +power - Huawei logo and vibration and shutdown, no fastboot
Battery disconnected, vol-+power and connecting cable to phone - the same
Battery disconnected combination vol + vol - + ppwer, with sd card dload, the same
Battery connected combination vol + vol - power, sd card dload, the same
Any other suggestions?
The phone is recognized in Windows in device manager as mobile device as volume with a letter, I cant change the drivers to the right ones. I can't enter the storage it's unrecognized format.
Any other suggestions?

it is easy to suggest others.. I too advised you.. but today i am facing the same problem...
what I tried:
Reinstalling the same ROM using dload method
Upgrading to other ROM (using both dload and flashing 4 image method)
Downgrading
Restoring from the backup
At one point, the phone booted up all well except the Wifi Module... So I flashed another ROM and stuck again...

yes, mine too... or I could say flashing succeeds but there's some problem with the boot partition... will get my phone today from the Customer Care and try again (if they can't repair).
you can try removing the back cover and unplugging the battery... that is one of the few things I will do today as I get my phone back..

ok made it back.. just flashed the boot.img from b594 (the one I was using when my mobile got bricked)... somehow made it back. But now I am having a problem with the battery. It doesn't charge when the device is switched on, only when the device is switched off... will see for few days, if there's problem will take it back to service centre again
I have already removed back cover and was trying to reconnect the battery to do clear run. But the only thing is discovered in windows is a driver for storage and I can't change the driver to ADB or FASTBOOT
Now I have connected phone w PC on adb devices I see only emulator-5554 device. In Device manager I see the storage as a Mobile Device.
Nope it was Bluestacks

Switch off your device and then connect it to PC but just hold the volume- key.. that should get you in fastboot mode... I did that and then flashed the boot.img of the current ROM. This should boot it up...

Hi,
I'm not very experienced with those root things and followed a tutorial to do so.
I unlocked the bootloader, had TWRP installed and root. This worked. Now I wanted to remove Root and TWRP and go back to the original state. I couldn't find the stock recovery file, so I installed the P996A04V1.3.0B13_MR2_sd_ssl.zip via TWRP from the SD Card. Till here it worked. I could enter the stock recover and boot the phone.
Then Android wanted to install a security update. I allowed it and this is where the problem started.
The install process stood still on 25% for minutes. I thought it stuck and pressed and hold the power button to reboot that I can wipe the memory. But nothing happened. But the installation Process continued suddenly. I had the feeling that this power key worked like a skip key. So maybe it didn't install a file where it was stuck.
After the installation reached 100% the screen switched to black and nothing worked anymore. I couldn't restart the phone or anything but I think the phone was doing something cause it consumed electricity. When I checked the phone hours later I noticed it was empty.
I can reach the unlocked bootloader now, but none of the selections works. Doing nothing to boot or select Recovery lead to black screen and stuck. Then I have to wait until the battery is empty again. Fastboot, Power Off just restart the phone and I end in the Bootmenu again. I can't even fully charge the phone. As soon as it has enough power to start the Bootmenu appears. So I don't see the display of the charging process.
I don't understand how this could happen. I tried different key combinations when the phone had enough electricty to start. The phone always restarts and end in the bootmenu. Only when I press all three keys it's standing still on the ZTE Logo screen but as soon as I release the keys I end again in the bootmenu.
How can I force another Update?
regards
Let' start with the basic questions:
Do you have proper backup of your data?
Which Android Version did your Axon had before it went unusable?
You could try to reflash TWRP.
Boot your phone into bootmode.
Download a proper TWRP Image on your PC (https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547)
Open a cmd shell (press the windows key and type 'cmd' -> press enter)
Navigate to the folder where the TWRP Image is stored ('
Code:
cd C:\Users\[I]YOUR_USER_NAME[/I]\Downloads\
')
Type: '
HTML:
fastboot flash recovery [I]TWRP_IMG_NAME.img[/I]
'
Afterwards you could try to reboot into recovery mode.
I don't have a backup. But there isn't something imortant on the phone that I want to keep. I can do a full reset and reinstall, too.
Android must have been the latest offical availabe what's in the file. Was it Android 8? V1.3.0B13
The fastboot mode doesn't work. The screen turns black and the LED blinks red but only for a moment. Then the phone restarts and I'm in the bootmenu again. Windows doesn't recognize it as device.
Is there a way to force it to do an update from my SDCard without it needed to be connected to a PC?

I don't know of any.
But you could boot into EDL Mode (Press and hold Both Volume button and then press the power button) and flash a Stock EDL rom from the Download Center i have linkd before.
It's not visible for the PC. The only thing I see is the charging screen when its total empty and you can't even boot as. As soon as it has enough power to switch to the normal screen the bootloader appears and when I do nothing the screen turns black and nothing happens. I don't even know if it is charging. The LED is off.
Follow this guide to unbrick it and then use MiFlash and flash an EDL ROM
